The sampling switching mechanism 32 includes a plurality of accommodating chambers 3211 and a rotation mechanism 321. The sampling bottle 31 is received. In the accommodating chamber 32111, the rotary mechanism 321 intermittently drives the sampling bottle 31 to selectively communicate with the outlet 3312 of the water pump. The inlet of the water pump 33 is connected to a pipeline. One end of the pipeline is immersed in the water to be sampled. The water in the sampling water area is pumped out and pumped into the sampling bottle to realize the collection of water samples in the sampling water area. After the sampling is completed, the hull moves to the next sampling water area for sampling. At this time, the sampling switching mechanism 32 is used to switch to the next sampling bottle. Similarly, the water sample in the sampling water area is injected into the sampling bottle through a water pump. Then, if one sampling is performed according to one sampling point, five sampling bottles in this embodiment can sample five sampling points, which greatly improves the sampling capability and the work efficiency.

Specifically, the slewing mechanism in this embodiment includes a slewing platform 3211 and a slewing drive assembly 3212. The accommodating cavities 32111 are uniformly distributed on the slewing platform 3211, and the slewing platform 3211 is fixed to the output end of the slewing drive assembly 3212. Motor or servo motor, reducer is set at the output of stepper motor and servo motor to reduce the speed of the output of stepper or servo motor. At this time, the rotary platform is fixed on the output shaft of the reducer. The rotation angle can be calculated by the number of rotations of the stepper or servo motor and the reduction ratio of the reducer.

Since the sampling assembly of this embodiment has multiple sampling bottles, how to inject the water sample drawn by the pump into the sampling bottle is a problem that needs to be solved. For this reason, this embodiment also includes a water injection mechanism 34, and the inlet of the water injection mechanism 34 It is in communication with the outlet of the water pump. The outlet of the water injection mechanism 34 is located at the water injection station. Each rotation of the slewing mechanism 321 can move the storage chamber located at the water injection station out of the water injection station, and at the same time, the rear storage chamber can enter the water injection station. Work station; during the interval of the slewing mechanism, the outlet of the water injection mechanism communicates with the sampling bottle in the containing cavity.

Specifically, a connecting piece 323 is fixed at the opening of the accommodating cavity in this embodiment. The connecting piece 323 closes the opening of the accommodating cavity 32111. The outer end of the connecting piece 323 has a smooth first sealing plane 3231. The sealing plane 3231 is provided with a water injection channel 3233, and the water injection channel 3233 communicates with the sampling bottle 31 in the accommodating cavity 32111. The outlet end of the water injection mechanism 34 has a second sealing plane 342 adapted to the first sealing plane 3231. When the cavity 32111 is located at the water injection station, the first sealing plane 3231 is in contact with the second sealing plane 342, the water injection channel 3233 is opposite to and connected to the outlet of the water injection mechanism 34, and passes through the water injection channel 3233 and the outlet of the water injection mechanism. The first sealing plane and the second sealing plane are closely adhered to form a seal, so that water does not leak during the water injection process. Preferably, the accommodating cavity 32111 is disposed through so that the accommodating cavity has a first opening 321111 and a second opening 321112, the connecting member 323 is fixed to the first opening 321111 of the accommodating cavity, and the collection bottle 31 is inserted into the container through the second opening 321112. The receiving cavity 32111 specifically includes a fixing member 324, and the upper end of the fixing member 324 is screw-connected with the connecting member 323. The fixing member is provided with a sampling bottle receiving cavity 3241, and the sampling bottle is inserted into the sampling bottle receiving cavity. It should be noted that, in order to realize that the first sealing surface plane and the second sealing plane have a longer life, it is preferable that the connecting member 323 in this embodiment may be metal or ceramic, and of course, it may also be a composite structure of the two.

Further preferably, in order to prevent the sampling bottle and the water injection channel from leaking, so that the sampling water leaks, the inner end of the connecting member 323 preferably has a groove 3234, the groove 3234 communicates with the water injection channel, and the groove 3234 is provided inside There are seals. The mouth 311 of the collection bottle is inserted into the seal. The seal fills the gap between the mouth 311 of the collection bottle and the groove 3234 to prevent leakage. Preferably, the bottle mouth of the collection bottle has a flange, and the outside diameter of the flange is larger than the outside diameter of the sampling bottle, so that the bottle mouth can be tightly wrapped by the sealing member, thereby further improving the sealing effect.

The bottle mouth 311 of the sampling bottle is fixed with a fixing piece 325, and a check valve is provided in the fixing piece 325. The check valve can only allow the fluid in the water injection channel to enter the sampling bottle, so that the sampling bottle can be prevented from being taken out and accommodated. Cavity or leakage during transportation.

Further, if the sampling liquid is directly injected into the sampling bottle and the air in the sampling bottle cannot be eliminated, Zhejiang will cause air blocking problems, which makes it difficult to inject the sampling liquid into the sampling bottle. For this reason, it is preferred in this embodiment that the sampling bottle 1 It includes an exhaust component, which exhausts the air in the sampling bottle when the sampling fluid is injected into the sampling bottle.

Specifically, the exhaust assembly includes an exhaust valve, which is fixed on the bottom of the sampling bottle 31. The first end 3131 of the exhaust valve faces the sampling bottle, and the second end 3132 of the exhaust valve communicates with the atmosphere. Specifically, a vent 312 is provided at the bottom of the sampling bottle (the end away from the opening 311 of the sampling bottle). When the sampling water is injected into the sampling bottle, the pressure in the sampling bottle rises and reaches the pressure at which the exhaust valve opens. The valve disc in the exhaust valve is opened, and the first end and the second end of the exhaust valve are communicated. Since the bottom of the sampling bottle faces vertically upward in this embodiment, the air in the collection bottle is passed by the exhaust valve. The vent hole 312 is discharged into the atmosphere, thereby solving the problem of difficulty in collecting water due to an increase in pressure in the sampling bottle during the water injection process.

s1. Place the water quality inspection boat in the water to be inspected, and use the terminal to connect with the signal through the control module;

s2. Control hull cruise through the terminal;

s3. The water area will be sampled when the designated sampling point is reached;

s4. The hull reaches the sampling points set in sequence and samples the waters at the sampling points;

s4. The hull returns to submit the sample, and the sample is tested by the inspector.

It should be noted that the hull control and remote control in this application are prior art, and this application merely borrows the hull control and remote control method or control circuit in the prior art to coordinate the actions of the hull and various agencies in this application, and can With reference to the application number cn201910391046.3, the name is a hull control and remote control method in a remotely controllable water quality inspection vessel.

Example two

In the actual implementation of the above embodiment, a water sample remaining in the water pump and the pipeline after the last sampling point is taken over, then this residual water sample will be mixed into that point when sampling at the next sampling point. In the sampling solution, contamination of the water sample at the next sampling point results in inaccurate detection and obvious deviations. In order to solve this problem, this embodiment further includes a first solenoid valve 333 and a second solenoid valve 334. The inlet ends of the solenoid valve 333 and the second solenoid valve 334 are connected in parallel with the outlet 3311 of the water pump. The outlet of the first solenoid valve 333 is connected with the inlet of the water injection mechanism 34. The outlet of the second solenoid valve 334 is directly connected to the outside; After that, the second solenoid valve opens synchronously with the water pump, and the first solenoid valve is closed; after a set time delay, the first solenoid valve opens and the second solenoid valve closes, so that the water pump and the remaining The water sample at a sampling point is discharged, and the delay time is sufficient to discharge the water sample at the previous sampling point, thereby solving this problem.
