When conducting segmented testing, since the gas content of each tunnel segment is different, one side needs to test each tunnel segment. However, after the existing detection device is installed, if its installation position has a certain error, it will not be located at the center of the current segment or cannot be installed due to structural influences. The inability to move and adjust the detector body will lead to an unsatisfactory and inaccurate detection structure. Utility Model Content

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Combine the following Figures 1 to 4 The utility model is described in detail.

[0024] A gas concentration detection device for a gas tunnel comprises a main body 1, a detector 2 is connected to one side of the main body 1, a detection rod 201 is connected to the top of the detector 2, a folding tube 202 is connected to one side of the detector 2, a contraction groove 203 is provided on one side of the detector 2, a stabilizing component is connected to one side of the contraction groove 203, and the stabilizing component is deflected and closed along a circular axis.

[0025] First, the main body 1 is connected to various places in the gas tunnel, and then the air in the tunnel is collected by the detection rod 201 on one side of the detector 2 and transported to the main body 1 for detection and collection of data for observation, so as to know the gas content in the tunnel.

[0026] Furthermore, the detector 2 is connected to the main body 1 through a folding tube 202, and the stabilizing component includes a folding rod 2031, a sleeve ring 2032, a limit block 2033 and a deflection shaft 204. The folding rod 2031 is connected to the middle top of the contraction groove 203, the sleeve ring 2032 is arranged at one end of the folding rod 2031, the limit block 2033 is arranged on the inner wall of the sleeve ring 2032, the deflection shaft 204 is connected to the middle of the sleeve ring 2032, and the folding rod 2031 is provided with two connections in the middle of the deflection shaft 204, and one end of one of the folding rods 2031 is connected to the main body 1, the folding rod 2031 is telescopically arranged, and the limit block 203 is a trapezoidal block connected by a spring in the groove on the inner wall of the sleeve ring 2032.

[0027] After the detector 2 is installed, when it is necessary to detect the area near the detector 2, the detector 2 can be separated from the main body 1 by applying a certain force to pull the detector 2. During separation, the folding tube 202 is extended to cooperate with the separation of the detector 2, so that the detector 2 will remain connected to the main body 1 after separation, so that different positions can be quickly detected without moving the main body 1, avoiding the situation where the main body 1 is fixed and cannot be conveniently disassembled when detecting the gas content in the tunnel in sections. The spacing between the detectors can be adjusted by moving the detectors 2, so that the tunnel can be detected in sections more accurately, and the detectors 2 can be directly moved to the tunnel structure where they cannot be installed for detection.

[0028] Furthermore, the deflection shaft 204 also includes a connecting ring groove 2041 and a limiting groove 2042. The connecting ring groove 2041 is an annular groove on the side wall of the deflection shaft 204. The limiting groove 2042 is a plurality of trapezoidal grooves around the connecting ring groove 2041. The connecting ring groove 2041 cooperates with the sleeve ring 2032. The limiting groove 2042 is a plurality of grooves that cooperate with the limiting block 2033.

[0029] At the same time, when the detector 2 is separated from the body 1, the two connected folding rods 2031 on the deflection shaft 204 will be pulled to deflect, so that the folding rods 2031 will rotate along the connecting ring groove 2041 on the deflection shaft 204 through the sleeve ring 2032, so that the two folding rods 2031 will expand and separate in a triangular shape to follow the separation of the detector 2 and the body 1. When the folding rod 2031 deflects along the connecting ring groove 2041, the limit block 2033 on the inner wall of the sleeve ring 2032 will move along the connecting ring groove 2041. When the detector 2 is separated from the body 1 to a suitable position, the limit block 2033 will be reset through the reset engagement of the spring at one end. At the same time, both ends of the folding rod 2031 are connected by the deflection shaft 204, so that both ends of the folding rod 2031 are limited by the engagement of the limit block 2033, so that the two folding rods 2031 will deflect automatically when deflecting, separating and extending. At the same time, due to the trapezoidal setting of the limit block 2033, when deflection or reset is required after engagement, the inclined surfaces on both sides will be squeezed when subjected to force so that it can shrink back for deflection, and when the folding rod 2031 is closed and reset, it will shrink into the shrinkage groove 203, so that the detector 2 and the main body 1 can be closed together.

[0030] The following is a specific implementation process of the utility model. First, the main body 1 is connected to various places in the gas tunnel. Then, the detection rod 201 on the detector 2 on one side collects the air in the tunnel and transports it to the main body 1 for detection and collection of its data for observation, so as to know the gas content in the tunnel. After the detector 2 is installed, when it is necessary to detect the area near the detector 2, the detector 2 can be pulled with a certain force to separate the detector 2 from the main body 1. During separation, the separation of the detector 2 is coordinated by the extension of the folding tube 202, so that the detector 2 will remain connected to the main body 1 after separation, so that different positions can be quickly detected without moving the main body 1, avoiding the situation that when the gas content in the tunnel is detected in sections, because the main body 1 is connected and fixed and cannot be conveniently disassembled and assembled, the spacing between the detectors can be adjusted by displacing the detectors 2, so that the segmented detection in the tunnel can be more accurately performed. At the same time, when the detector 2 is separated from the main body 1, the two connected folding rods 2031 on the deflection shaft 204 will be pulled to deflect, so that the folding rods 2031 will pass through the sleeve ring 20 32 rotates along the connecting ring groove 2041 on the deflection shaft 204, so that the two folding rods 2031 will expand and separate in a triangular shape to follow the separation of the detector 2 and the body 1. When the folding rod 2031 deflects along the connecting ring groove 2041, the limit block 2033 on the inner wall of the sleeve ring 2032 will move along the connecting ring groove 2041. When the detector 2 and the body 1 are separated to a suitable position, the limit block 2033 will be reset and engaged into the corresponding limit groove 2042 through the reset of one end spring. At the same time, both ends of the folding rod 2031 are The connection is made through the deflection axis 204, so that both ends of the folding rod 2031 are limited by the engagement of the limit block 2033, so that the two folding rods 2031 will deflect automatically when deflected, separated and extended. At the same time, due to the trapezoidal setting of the limit block 2033, when deflection or reset is required after engagement, the inclined surfaces on both sides will be squeezed when subjected to force so that it can shrink back for deflection, and when the folding rod 2031 is closed and reset, it will shrink into the shrinkage groove 203, so that the detector 2 and the main body 1 can be closed together.
