[0032] The working principle of a landfill gas detection and collection device provided by the utility model is as follows: by setting an adjustment structure 4, first press the air pump 405, and the air pump 405 inflates the balloon 409 through the air pipe 404. During this process, the volume of the balloon 409 increases and props up the piston 410. The piston 410 and the sealing ring 411 move along the inner wall of the circular tube 1 toward the direction close to the cover plate 3. The piston 410 drives the round rod 412 to slide along the bottom plate 2. The spring 413 is always in a stretched state. Continue to operate the air pump 405 until the piston 410 fits the cover plate 3 to fully discharge the gas in the circular tube 1. Then operate the handle 406 to move the circular tube 1 to the designated area. Then pull the air pump 405 to separate the air pump 405 from the air pipe 404. The gas in the balloon 409 flows out through the air pipe 404. The spring in the stretched state The spring 413 gives the piston 410 an elastic force in the opposite direction, so that the piston 410 moves in the direction away from the cover plate 3. During this process, the piston 410 and the sealing gasket cooperate to draw the landfill gas at the designated location into the regulating tube through the installation tube 401, and then the regulating tube is retracted, and the round cover 402 is closed on the installation tube 401. Subsequently, the detection tube on the detector is connected to the installation tube 401, and the air pump 405 is operated to inflate the balloon 409 to discharge the landfill gas from the regulating tube and input it into the detector through the detection tube. Among them, the round cover 402 is tied to the cover plate 3 by the connecting rope 403, which can effectively prevent the round cover 402 from being lost. The air pipe 404 is limited to the side of the handle 406 by two support frames 407, which makes the overall look neater and more convenient for arrangement and operation. The anti-slip pad 408 increases the friction of the arc surface of the handle 406, which is convenient for users to operate the handle 406.

[0033] By setting the auxiliary structure 5 and rotating the bidirectional screw 52, the bidirectional screw 52 drives the two moving frames 53 to move along the auxiliary frame 51 in a direction approaching each other by means of the thread. During this process, the moving frame 53 drives the clamping ring 54 to move. Continuing to rotate the bidirectional screw 52 until the two clamping rings 54 move in a direction approaching each other and clamp and fix the detection tube on the installation tube 401. Among them, the two moving frames 53 are further limited by the sliding rod 55, so that the moving frame 53 is more stable when moving along the auxiliary frame 51. The friction at both ends of the bidirectional screw 52 is increased by the anti-slip protrusion 56, which facilitates the user to rotate the bidirectional screw 52.
