detailed description

The present invention is not limited by the following embodiments, and a specific implementation manner can be determined according to the technical solution and actual situation of the present invention.

In the present invention, for the convenience of description, the description of the relative positional relationship of each component is described in accordance with the layout of FIG. 1 in the specification, such as the positional relationship of front, back, up, down, left, and right. It is determined according to the layout direction of the drawings of the specification.

The present invention is further described below with reference to the embodiments and the accompanying drawings:

As shown in FIG. 1, the SF6 gas cylinder heating device includes a cart, a heating cylinder, a heating belt 1, a temperature controller 2 and a temperature sensor 3. The cart includes a bottom plate 4, a push arm and a roller 5, and a bottom plate 4 A roller 5 is provided, and a hand pushing arm is provided on the bottom plate 4. The heating cylinder includes a left half cylinder 6 and a right half cylinder 7 which are vertically placed on the bottom plate 4. The front and back sides of the left half cylinder 6 are respectively right and right. The front and back sides of the half-cylinder 7 are detachably connected together by a lock 8; the right half-cylinder 7 is fixedly connected to the bottom plate 4; the inner wall of the left half-cylinder 6 and the inner wall of the right half-cylinder 7 are provided with heating vertically. Band 1, the inner wall of the right half cylinder 7 is provided with a temperature sensor 3, the push arm is provided with a temperature controller 2, the heating belt 1 and the temperature controller 2 are electrically connected, the temperature controller 2 and the temperature sensor 3 are electrically connected, and the temperature A power cord is connected to the controller 2. As required, the lock 8, the heating belt 1, the temperature controller 2 and the temperature sensor 3 can all adopt the existing known technology. For example, the heating belt 1 can be produced by Nanjing Feituo Electrical Engineering Co., Ltd. (zr) zbr-j The heating belt 1, temperature controller 2 and temperature sensor 3 can be integrated. The model is ai-516d7e7 rail-mounted temperature control module (with digital display) card rail type pid produced by Xiamen Yudian Automation Technology Co., Ltd. The regulator and the heating cylinder are detachably docked together by the left half cylinder 6 and the right half cylinder 7 through the lock buckle 8 to facilitate the access to the sf6 cylinder. The setting of the cart not only facilitates the movement of the device, but also facilitates Transport sf6 gas cylinders, which solves the problem of time and effort when manually transporting sf6 gas cylinders, and improves the work efficiency of the gas filling operation. When in use, remove the left half cylinder 6 first, put it in the sf6 gas cylinder, and then install the left The half-cylinder body 6 is then connected to the power supply line on the temperature controller 2 to heat the SF6 gas cylinder at a low temperature. The structure of the invention is simple and convenient to use.

According to actual needs, the above sf6 gas cylinder heating device can be further optimized or / and improved:

As shown in FIG. 1, two heating belts 1 are provided on the inner wall of the left half-cylinder 6 at intervals, three heating belts 1 are provided on the inner wall of the right half-cylinder 7, and five temperature controls are provided on the temperature controller 2. Switch, the five heating bars are electrically connected to the five temperature control switches one by one respectively. Specifically, the temperature controller 2 is manufactured by Xiamen Yudian Automation Technology Co., Ltd. The model is ai-516d7e7 rail-mounted temperature control module (with digital display) card rail pid regulator. The setting of five heating belts 1 not only ensures sf6 gas. The bottle is evenly heated, and the number of working strips of the heating belt 1 can be selected according to the outdoor temperature to prevent insufficient heating or overheating problems.

As shown in FIG. 1, the push arm includes two vertical rods 9, two horizontal push rods 10, a vertical connection plate and a horizontal connection plate. The two vertical rods 9 are vertically fixed on the right side of the bottom plate 4 in the front-to-back direction. A vertical connection plate is connected between the rods 9, the outer side wall of the right half cylinder 7 and the vertical connection plate are fixedly connected, and the left ends of the two horizontal push rods 10 and the tops of the two vertical rods 9 are fixedly connected to each other one by one, two A horizontal connection plate is connected between the horizontal push rods 10, and a temperature controller 2 is installed on the horizontal connection plate. The connection strength between the right half cylinder 7 and the cart is strengthened by the setting of the vertical connection plate, the push cart is facilitated by the setting of the vertical rod 9 and the horizontal push rod 10, and the temperature controller is facilitated by the setting of the horizontal connection plate. 2 installation.

The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect, and may add or remove non-essential technical features according to actual needs to meet the needs of different situations.
