Working principle: When using the rice fish pond water monitoring and sampling device, according to Figs. 1 and 2, the housing 1 is moved by the universal self-locking wheel 2 to the position where sampling is required, and the bolt 4 is loosened and the first hand is rotated Wheel 3, so that the first hand wheel 3 drives the drum 5 to rotate and relax the first connecting chain 6, the first connecting chain 6 no longer pulls the fixing rod 7, and the fixing rod 7 will pop out and expand under the action of the compression spring 9 The block 10 drives the telescopic block 10 to expand and contract. After determining the area to be sampled by rotating the first hand wheel 3, the bolt 4 can be locked to prevent the first hand wheel 3 from moving. At this time, the cylindrical block 8 reaches the required position. Sampling area

When the area to be sampled is reached, according to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the second hand wheel 12 on the support block 11 is rotated to cause the second hand wheel 12 to drive the fixed column 13 to rotate to the second connection chain. 14 relax, under the action of gravity, the sampling box 15 will drive the second connection chain 14 to slide downward to achieve the purpose of lowering the sampling box 15. When the sampling box 15 enters the pool water, the water will enter from the water inlet 16 to Inside the sampling box 15, at this time, the buoyancy of the airbag 21 will be greater than the force of the return spring 22 to drive the fixed block 20 to slide upward, so the fixed block 20 will drive the blocking plate 19 to slide upward to expose the collection bin 17, and water will enter from The collection bin 17 is filtered by the filter plate 18 to achieve the collection of the water filtered by the filter plate 18 and the unfiltered water quality for convenient water quality detection. Then, the second hand wheel 12 is rotated, so that the second connection chain 14 will The sampling box 15 is pulled up. When the airbag 21 is no longer subjected to buoyant force, the return spring 22 will cause the fixed block 20 to drive the blocking plate 19 to slide down and block the collection bin 17 to prevent the overflow of the collection bin 17 and achieve good Collection effect, increase Overall practicality.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the invention is defined by the appended claims and their equivalents.
