[0002] Gas fire extinguishing cylinders are a key component in gas fire extinguishing systems, used to store fire extinguishing agents such as carbon dioxide, heptafluoropropane, etc. When a fire occurs, the fire extinguishing agent is quickly released through pipes and nozzles to extinguish the fire. Gas fire extinguishing cylinders are usually made of high-strength steel with good pressure resistance and sealing to ensure that the fire extinguishing agent will not leak during storage. A pressure gauge is installed on the cylinder to monitor the internal pressure and ensure that the fire extinguishing agent is in a normal state.

[0003] In addition, gas fire extinguishing cylinders need to be regularly inspected and maintained to ensure their safety and effectiveness. Inspections include appearance inspection, pressure test, leak test, wall thickness measurement, water pressure test, internal inspection, valve and component inspection, etc., to ensure that the cylinders can work normally when a fire occurs, release the fire extinguishing agent in time, and effectively extinguish the fire.

[0004] In the above technology, when the gas fire extinguishing cylinder is subjected to various tests, the cylinder is generally placed in different testing locations and tested item by item using different testing instruments.

[0008] By adopting the above technical scheme, an air injection pipe and a water injection pipe are arranged on the inspection table. The water injection pipe is connected to the inside of the steel cylinder so that water can be injected into the steel cylinder for leakage test, and the air tightness and pressure test of the steel cylinder can be completed by injecting gas into the steel cylinder through the air injection pipe. The two baffles are rotated by the driving mechanism to cover the inspection slot, and water or air can be injected into the inspection slot through the water injection pipe or the air injection pipe to complete the water pressure test and air pressure test of the steel cylinder.

[0013] By adopting the above technical solution, when it is necessary to drive the two baffles to close the detection slot, the first driving cylinder is started to drive the driving plate to rotate. After the driving plate rotates to a horizontal state, the second driving cylinder is started. The second driving cylinder is started to drive the baffle to move. Under the action of the second driving cylinder, the baffle is pressed against the detection table and blocks the opening of the detection slot. When it is necessary to open the detection slot, it is only necessary to start the first driving cylinder and the second driving cylinder to move the driving plate and the baffle back to their original positions, thereby completing the baffle movement work.

[0025] By adopting the above technical solution, when the second connecting ring is moved to be plugged into the first connecting ring, the second connecting ring is first rotated so that the second limit block on the second connecting ring is aligned with the through hole on the first limit block, and then the second limit block is moved to contact the inner bottom wall of the connecting groove. After the second limit block is located between the first limit block and the inner bottom wall of the connecting groove, the electromagnet block starts to adsorb the second limit block. The second limit block moves and presses against the electromagnet block under the action of the electromagnet block, thereby completing the fixing of the position of the second limit ring by clamping the second limit block between the first limit block and the inner bottom wall of the connecting groove.

The two baffles 16 not only seal the detection slot 11, but also reduce the probability of the cylinder rupturing under various pressure tests and causing harm to the staff. In summary, the cylinder can complete the appearance inspection, pressure test, leakage test, water pressure test and other inspections in the detection slot 11 of the inspection table 1, without the need to frequently change the inspection site, which greatly improves the work efficiency of the inspection.

A circular arc-shaped guide surface 18 is provided on the side surface of the part of the second limiting block 36 that passes out of the sliding groove 38 near the inner bottom wall of the connecting groove 34.

[0056] Reference Figure 2 and Figure 3 , the electromagnet block 37 is fixedly mounted on the inner bottom wall of the connection groove 34, and the electromagnet block 37 can adsorb the second limit block 36 after being energized.
