The counterweight boxes 2 are loaded with sand. A feed port is opened on the top of the counterweight box 2, and a discharge port is opened on the side of the counterweight box 2. The electric push rod 5 is located between the two counterweight boxes 2. The counterweight boxes 2 can be used to increase the counterweight of the electric cart 1 to ensure the stability of the electric cart 1 when moving.

[0032] As a technical optimization solution of the present invention, an installation groove is opened on the side of the installation block 20 away from the multi-stage electric telescopic rod 11, and a mounting seat is installed in the installation groove. The gas concentration monitoring probe 21 is installed on the mounting seat. The mounting seat can facilitate the installation of the gas concentration monitoring probe 21, and the installation groove can facilitate the installation of the mounting seat on which the gas concentration monitoring probe 21 is installed.

[0033] When the present invention is used and the underground gas concentration needs to be monitored, first, the electric push rod 5 is started, and the piston rod of the electric push rod 5 pushes the mounting plate 6 upward until the mounting plate 6 is moved to the center of the mine and then stops.

[0034] At this time, the two multi-stage electric telescopic rods 11 are started at the same time, and the piston rods of the multi-stage electric telescopic rods 11 push the strip plate 12 to move away from the fixed plate 10 until the distance between the two strip plates 12 is 20 cm smaller than the diameter of the mine hole and then stops.

[0035] When the strip plate 12 moves away from the fixed plate 10, several mounting blocks 20 thereof move away from the fixed plate 10 at the same time, and the distance between two adjacent mounting blocks 20 gradually increases, and the distance between every two adjacent mounting blocks 20 is equal. The elasticity of the spring 24 can be used to make several mounting blocks 20 move away from the fixed plate 10 at the same time, and at the same time, the coordinated use of the spring 24, the guide rod 23 and the sleeve 22 can make the distance between several mounting blocks 20 equal, and then unfold several mounting blocks 20, and then unfold several gas concentration monitoring probes 21 installed on the sides of several mounting blocks 20, so that several gas concentration monitoring probes 21 are unfolded in a uniformly distributed state, and the distance between each gas concentration monitoring probe 21 is equal.

[0036] At this time, start the motor 8, and the output shaft of the motor 8 drives the mounting plate 9 to rotate. The rotation of the mounting plate 9 can drive the fixed plate 10 to rotate, and the fixed plate 10 drives the two multi-stage electric telescopic rods 11 to rotate. The piston rod of the multi-stage electric telescopic rod 11 drives the strip plate 12 to rotate, thereby causing a number of mounting blocks 20 to rotate, and then causing a number of evenly distributed gas concentration monitoring probes 21 to rotate, so that during the rotation of a number of gas concentration monitoring probes 21, the gas concentration at that location in the mine can be rotated to monitor the gas concentration in the mine. It utilizes a number of gas concentration monitoring probes 21 to be evenly distributed laterally, and during the rotation of a number of gas concentration monitoring probes 21, the gas concentration in the mine is monitored, which can comprehensively monitor the gas concentration of the mine at that location, and the positions of a number of gas concentration monitoring probes 21 rotate in real time, which can comprehensively monitor the gas concentration at that location in the mine, thereby improving the comprehensiveness of gas concentration monitoring in the mine.

[0037] In addition, the electric cart 1 can move in the mine tunnel, so that the electric cart 1 can move along the mine tunnel to conduct a thorough and comprehensive monitoring of the gas concentration in the mine tunnel.

[0038] When several gas concentration monitoring probes 21 monitor the gas concentration in the mine, when the piston rod of the multi-stage electric telescopic rod 11 pushes the strip plate 12 to move away from the fixed plate 10, the strip plate 12 can pull the elastic cloth 14 to unfold it. The unfolding of the elastic cloth 14 can make several suction fans 15 located behind several gas concentration monitoring probes 21. When the suction fans 15 are started, the suction fans 15 can inhale the air in the mine, and then the air in the mine can flow toward the gas concentration monitoring probes 21, which is convenient for the gas concentration monitoring probes 21 to quickly monitor the gas concentration in the air in the mine, and the gas in the mine can flow toward the suction fans 15. When the gas flows in the direction of the gas concentration monitoring probes 21, the gas passes through several gas concentration monitoring probes 21. Several gas concentration monitoring probes 21 can be used to monitor the passing gas, and then the gas concentration in the air is monitored, thereby ensuring the efficiency of gas concentration monitoring in the mine.

[0039] And the multi-stage electric telescopic rod 11 is used to push the strip plate 12 to move away from the fixed plate 10, so that a plurality of gas concentration monitoring probes 21 are deployed. The distance between the two strip plates 12 can be adjusted according to the diameter of the mine hole, so that mine holes of different diameters can be used and the gas concentration in mine holes of different diameters can be comprehensively monitored.

[0040] After the gas concentration monitoring in the mine is completed, the multi-stage electric telescopic rod 11 is started again, and the piston rod of the multi-stage electric telescopic rod 11 drives the strip plate 12 to move closer to the fixed plate 10, so that the two strip plates 12 move closer to each other, and the several deployed gas concentration monitoring probes 21 can be folded up. The deployed gas concentration monitoring probes 21 can be folded up to reduce the occupied space, and when the two strip plates 12 move closer to each other, the deployed elastic cloth 14 can be folded up, and then the deployed suction fan 15 can be folded up to avoid the elastic cloth 14 and the suction fan 15 occupying too much space. When the device is not in use, the several deployed gas concentration monitoring probes 21 and the elastic cloth 14 can be folded up to reduce the occupied space, making the device convenient and flexible to use.

[0041] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
