[0024] The recycling structure 9 comprises an air pump 901 fixedly connected to the right side of the semi-hollow block two 4, an air pipe one 902 fixedly connected between the air pump 901 and the semi-hollow block two 4, an air pipe two 903 fixedly connected to the output end of the air pump 901, an air tank 904 movably connected to the other end of the air pipe two 903, a square slot 905 formed in the right side of the shielding plate 8, two square slots 905 provided, a square block 906 arranged inside the square slot 905, the square block 906 and the shielding plate 8 being slidingly connected, the square block 906 and the air tank 904 being fixedly connected, a rotating slot 907 formed in the right side of the shielding plate 8, two rotating slots 907 provided, a rotating shaft 908 arranged inside the rotating slot 907, a blocking block 909 fixedly connected to the right end of the rotating shaft 908, the rotating shaft 908 and the shielding plate 8 being rotatably connected, the blocking block 909 and the square block 906 being slidingly connected, and the blocking block 909 and the shielding plate 8 being slidingly connected. Before the pipeline gas is transmitted, the space formed by the semi-hollow block one 3 and the semi-hollow block two 4 is usually pumped to a vacuum state by the vacuum pump 11. When the gas leaks and the buzzer 10 rings, the air pump 901 is started, the gas is transported into the air tank 904 through the air pipe one 902 and the air pipe two 903, when the air tank 904 is full of air, the air pipe two 903 connected to the air tank 904 is first disassembled, the gas inlet of the air pipe two 903 is provided with a one-way valve, which only allows gas to enter and does not allow gas to exit, then the staff rotates the blocking block 909 to move the air tank 904, and at the same time, the square block 906 is slid out of the square slot 905, then the gas in the air tank 904 is handled, the blocking block 909 is rotated out, the square block 906 of the empty air tank 904 is slid into the square slot 905, then the blocking block 909 is rotated to block the square block 906 from moving randomly, then the air pipe two 903 and the air tank 904 are connected, and the semi-hollow block one 3, the semi-hollow block two 4, the sealing structure 5, the gas sensor 7, the shielding plate 8 and the recycling structure 9 are arranged, so that the pipeline gas leakage can be detected in time, and the leaked gas can be recycled into the air tank 904 for secondary use, thereby reducing the waste of gas.

[0025] Working principle: Workers connect and secure pipes 1 and 2 using flanges. Then, semi-hollow blocks 3 and 4 create a space at the pipe connection. A sealing structure 5 prevents gas leakage. Before gas transmission, a vacuum pump 11 evacuates the gas from the space formed by semi-hollow blocks 3 and 4 through gas pipe 12, creating a vacuum. When gas leaks, gas sensor 7 detects gas being transmitted through the pipe within the space formed by semi-hollow blocks 3 and 4. Buzzer 10 sounds to alert staff of a gas leak at the gas connection. Simultaneously, the recovery structure 9 is activated to draw gas into the gas tank 904. Then, staff stop gas transmission. When gas sensor 7 detects that there is no more gas being transmitted from the pipe in the internal space, buzzer 10 stops sounding, and air pump 901 stops starting. Then, staff open sealing structure 5, repair the leak at the pipe connection, and then close sealing structure 5 again. The space formed by semi-hollow block 1 3 and semi-hollow block 2 4 is then vacuumed. Gas transmission resumes, and if buzzer 10 does not sound, the repair is complete. During this process, solar panel 6 provides power, saving energy and protecting the environment.
