[0021] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a pipeline gas detection device that is easy to disassemble and assemble, comprising: a pipeline main body 1, a mounting seat 2 is fixedly installed on the upper part of the outer periphery of the pipeline main body 1, two limit grooves 7 are arranged in the mounting seat 2, and the two limit grooves 7 are centrally symmetrically distributed along the axial direction of the mounting seat 2; a connecting pipe 5, the connecting pipe 5 is arranged in the mounting seat 2, a main machine 4 is fixedly installed on the top of the connecting pipe 5, and a solenoid valve 8 is fixedly installed on the lower part of the inner periphery of the connecting pipe 5; a quick disassembly and assembly mechanism 3, the quick disassembly and assembly mechanism 3 includes an installation cavity 36, the installation cavity 36 is centrally symmetrically arranged on the outer periphery of the connecting pipe 5, and limit blocks 35 are slidably installed in the installation cavity 36, and the limit blocks 35 are mutually away from the middle of one end. A limit pin 37 that is compatible with the limit groove 7 is fixedly installed, and a return spring 34 is arranged in the installation cavity 36. When the connecting pipe 5 is inserted into the installation seat 2, the limit pin 37 will abut against the limit groove 7, and the limit pin 37 will move into the installation cavity 36. At the same time, the return spring 34 will be compressed. When the limit pin 37 moves to the bottom of the limit groove 7 with the connecting pipe 5, the connecting pipe 5 is rotated. Since the limit groove 7 is L-shaped and the depth of the bottom groove of the limit pin 37 is greater than the upper part of the limit groove 7, the limit pin 37 will cooperate with the return spring 34 to engage in the limit groove 7, so that the connecting pipe 5 can be quickly installed, reducing the use of fixing bolts and improving the installation efficiency of the gas detection device.

[0023] A micro fan 6 is fixedly installed on the upper part of the outer periphery of the connecting pipe 5, and the host 4 is electrically connected to the micro fan 6 and the solenoid valve 8 respectively. The host 4 can open the solenoid valve 8 by controlling the solenoid valve 8. At this time, the host 4 controls the micro fan 6, and cooperates with the connecting pipe 5 to suck the gas in the pipeline body 1 into the host 4. The gas detection sensor in the host 4 can detect the gas. Here, the gas sensor can use one or more of a combustible gas sensor, a toxic gas sensor, a harmful gas sensor, etc. The gas detection sensor can detect the gas in the pipeline body 1 and transmit the detection result to the staff through the external network, which is beneficial for the staff to detect the gas in the pipeline body 1. One end of the reset spring 34 is fixedly installed on the limit block 3 on the same side. 5 is away from the middle of one side of the limiting pin 37, and the other end of the reset spring 34 is fixedly installed in the middle of the inner wall of the mounting cavity 36 on the same side. A fixed plate 31 is fixedly installed on the upper part of the outer periphery of the connecting pipe 5, and a compression spring 32 is fixedly installed on the lower part of the fixed plate 31. A movable plate 33 is fixedly installed on the bottom end of the compression spring 32, and the movable plate 33 is slidably installed on the lower part of the outer periphery of the connecting pipe 5. The limiting grooves 7 are all L-shaped. When the connecting pipe 5 is installed in the mounting seat 2 through the quick disassembly mechanism 3, the compression spring 32 cooperates with the fixed plate 31 and the movable plate 33, and the movable plate 33 can be tightly sleeved on the mounting seat 2. Since a sealing gasket is provided in the mounting seat 2, the airtightness between the detection device and the pipeline body 1 can be improved, and the gas in the pipeline body 1 can be prevented from leaking during the detection process.

[0024] During actual use, the staff will insert the connecting pipe 5 into the mounting seat 2, at which time the limit pin 37 will abut against the limit groove 7. When the limit pin 37 moves to the bottom of the limit groove 7, the connecting pipe 5 is rotated 90° clockwise, and the detection device can be quickly installed with the help of the reset spring 34. In addition, the compression spring 32 cooperates with the movable plate 33 and the fixed plate 31 to tightly sleeve the detection device on the mounting seat 2, thereby increasing the airtightness of the detection device. Then the host 4 can control the solenoid valve 8 and the micro-blower 6 to draw the gas in the pipeline body 1 into the host 4. The gas detection sensor in the host 4 will detect and analyze the gas in the pipeline body 1. When the detection device needs to be disassembled, the staff will rotate the connecting pipe 5 90° counterclockwise. Since the limit groove 7 and the limit pin 37 are chamfered, at this time, the limit pin 37 can move upward along the limit groove 7, and the staff can remove the detection device from the pipeline body 1.

[0025] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
