[0044] The detection mechanism 6 includes a pressure detector one 61 installed on one side of the pipe body 1, one side of the high-pressure tank 22 is installed with a pressure detector two 62.

[0045] The top of the high-pressure tank 22 is fixed with a controller 7, the controller 7 is electrically connected with the pressure detector one 61, the pressure detector two 62 and the motor 51.

[0046] Working principle:

[0047] The pressure detector one 61 obtains the gas pressure in the pipe body 1 and transmits it to the controller 7, after the gas pressure exceeds the specified value, the electric valve is started to open the connection channel with the high-pressure tank 22, the gas will enter between the extrusion plate 35 and the gas blocking plate 36, then the gear 52 is driven by the motor 51 to rotate forward, the gear 52 forward rotation meets the rotation direction of the one-way gear one 33 to drive the reciprocating screw one 32 to rotate, the reciprocating screw one 32 rotation makes the L-shaped push rod 34 push the extrusion plate 35 to move to the direction of the gas blocking plate 36, compresses the gas between the two, because the pressure between the extrusion plate 35 and the gas blocking plate 36 gradually increases, the sealing plate two 314 will be tightly pressed against the extrusion plate 35 to close the gas passage two 311, so that the gas on the other side of the extrusion plate 35 cannot open the sealing plate two 314, the gas pressure of the gas compressed by the extrusion plate 35 will increase, after the gas pressure increases, it will push the sealing plate one 310 on one side of the gas blocking plate 36 to pull the spring one 39 to open the gas passage one 37 to enter the other side of the gas blocking plate 36, then the spring one 39 pulls the sealing plate one 310 to close the gas passage one 37 to avoid gas leakage;

[0048] After the extrusion plate 35 is attached to the gas blocking plate 36, the L-shaped push rod 34 moves to the tail of the screw thread at one end of the reciprocating screw 32, and the reciprocating screw 32 continues to rotate to make the L-shaped push rod 34 pull the extrusion plate 35 to reset. When the extrusion plate 35 resets, negative pressure is generated between the extrusion plate 35 and the gas blocking plate 36, so that the second sealing plate 314 pulls the second spring 313 to open the second gas passage 311, and the extrusion plate 35 resets. In the process of resetting, the gas (the gas enters when the extrusion plate 35 pushes the gas to the other side of the gas blocking plate 36) between the extrusion plate 35 and the side plate 23 enters the extrusion plate 35 and the gas blocking plate 36 through the second gas passage 311. After the extrusion plate 35 moves to the tail of the screw thread at the other end of the reciprocating screw, the extrusion plate 35 continues to push the gas between the extrusion plate 35 and the gas blocking plate 36 to the other side of the gas blocking plate 36. The pressure detector 62 detects the gas pressure pushed to the other side of the gas blocking plate 36. When the internal gas pressure reaches a fixed value, it has reached the limit of the pressure storage of the high-pressure tank 22, and the pressure of the pipe body 1 cannot be further compressed to relieve the pressure.

[0049] When the gas pressure in the pipe body 1 becomes smaller, the motor 51 drives the gear 52 to reverse, and the gear 52 reverses to meet the rotation direction of the reciprocating screw 42 driven by the one-way gear 42, so that the reciprocating screw 41 moves the push plate frame 43 to the tail of the screw thread at one end of the reciprocating screw 41, and the back-shaped plate 44 pushes the rammer 45 to insert into the inside of the gas passage 37 and pushes the first sealing plate 310 to stretch the spring 39 to open the gas passage 37. The previously compressed gas returns to the pipe body 1 through the gas inlet pipe 21, compensates the pipe body 1, and also reduces the pressure of the high-pressure tank 22, which is convenient for storing and relieving the pipe body 1 when the gas pressure is too high.

[0050] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
