The conical elastic A positioning rod 12 is fixedly installed on the side of the blocking block 10 away from the gas storage tank 100, wherein a connecting block is adhesively fixed on the side of the conical elastic blocking block 10 away from the gas storage tank 100, and the connecting block is fixedly connected to the corresponding positioning rod 12, and a positioning sleeve 11 is slidingly sleeved on the positioning rod 12, wherein a limiting hole is provided on the inner wall of one side of the positioning sleeve 11, and a limiting block slidingly connected to the corresponding limiting hole is fixedly connected to one side of the positioning rod 12, and the limiting block cooperates with the corresponding limiting hole to limit and prevent the positioning rod 12 from falling off, and the positioning sleeve 11 cooperates with the corresponding positioning rod 12 to vertically guide the conical elastic blocking block 10.

In addition, when the gas leaks accidentally, it can timely alarm to remind personnel to carry out maintenance work, thereby improving the timeliness of maintenance.

[0026] Working principle: during use, when the protective cover 3 is not installed, gas can be directly supplied to the gas storage tank 100 through the gas inlet valve 104, and the gas inside the gas storage tank 100 can be discharged through the gas outlet valve 105. When protecting the gas inlet valve 104 and the gas outlet valve 105, the conical elastic blocking block 10 is sleeved in the corresponding connecting pipe 8, and then the two protective covers 3 are respectively sleeved on the gas inlet valve 104 and the gas outlet valve 105, and the protective cover 3 drives the corresponding elastic sealing ring 15 to contact with the mounting plate 4, and then the corresponding T-shaped quick-fix bolt 6 is rotated forward, and the T-shaped quick-fix bolt 6 rotates in the corresponding fixing block 7 and moves into the threaded sleeve 5.

[0027] When the protective cover 3 moves, the corresponding positioning sleeve 11 is also squeezed, and the positioning sleeve 11 slides on the corresponding positioning rod 12. When the positioning sleeve 11 moves, the corresponding compression spring 13 is compressed, and the compression spring 13 squeezes the conical elastic block 10 through the corresponding connecting block, so that the conical elastic block 10 is in close contact with the inner wall of the corresponding connecting pipe 8, thereby achieving effective blocking of the connecting pipe 8, and by blocking the connecting pipe 8, a secondary blocking effect is achieved. When the gas leaks through the inlet of the gas inlet valve 104 and the outlet of the gas outlet valve 105, the connecting pipe 8 is blocked by the corresponding conical elastic block 10 at this time, so that the gas will not leak out, which can effectively reduce the risk of gas leakage caused by leakage of the gas inlet valve 104 and the gas outlet valve 105.

[0028] When the gas leaks accidentally, the gas will enter the protective cover 3, and the gas detection sensor 9 will detect the situation inside the corresponding protective cover 3. When the gas is detected, the gas detection sensor 9 will transmit the signal to the controller 1, and the controller 1 will control the corresponding sound and light alarm 2 to send out sound and light alarm to remind the personnel. By timely reminding the personnel when the gas leak is detected, it is convenient for the personnel to perform maintenance operations in time after hearing the alarm, thereby improving the timeliness of maintenance;

[0029] In addition, since the protective cover 3 protects the outer sides of the gas inlet valve 104 and the gas outlet valve 105, the gas will not leak into the external environment, thereby effectively reducing the impact of gas leakage on the environment and improving the safety of use;

[0030] When it is necessary to supply gas to the inside of the gas storage tank 100 or release the gas in the future, the T-shaped quick-fix bolt 6 can be rotated to separate it from the corresponding threaded sleeve 5 to release the fixation of the protective cover 3, and the protective cover 3 can be directly removed. When the protective cover 3 is removed, the blocking of the positioning sleeve 11 is released, so that the compression spring 13 in the compressed state is gradually reset. When it is fully reset, the positioning sleeve 11 can be pulled out of the connecting pipe 8 through the corresponding compression spring 13 to remove the blockage, and the external gas pipeline can be connected through the mounting ring 14, and the gas inlet valve 104 or the gas outlet valve 105 can be opened to realize the gas supply or gas release operation.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
