[0002] Natural gas, as a clean energy source, has been widely used globally. With the rapid development of the natural gas industry, the safe operation of natural gas transmission and distribution systems has become particularly important. Especially in the stages of natural gas extraction, processing, and transmission, the inspection and maintenance of gas pipelines are crucial. Gas pipeline inspection equipment is a key tool for ensuring the safe operation of natural gas extraction, gathering, and transmission stations. This equipment can perform regular inspections of gas pipelines, identify potential leaks and corrosion areas, and assess the overall health of the pipelines. By detecting and repairing problems early, serious safety accidents such as explosions and fires can be prevented, while also ensuring the efficient transmission of natural gas.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] An embodiment of this utility model provides a gas pipeline detection device, which includes:

[0032] Detection assembly 1 includes a toothed ring 11 and a detection element 12. The toothed ring 11 can be fitted over the gas pipeline, and the detection element 12 is disposed on the toothed ring 11 with the detection direction facing the inside of the toothed ring 11; and

[0033] The traveling assembly 2 includes a traveling mechanism 21 that can be installed on the gas pipeline and move along the axial direction of the gas pipeline, and a connecting mechanism 22 disposed on the traveling mechanism 21.

[0034] The connecting mechanism 22 includes an assembly groove 221 and a gear 222 disposed in the assembly groove 221. An assembly gap is formed between the gear 222 and the groove wall of the assembly groove 221. The gear ring 11 passes through the assembly gap and meshes with the gear 222.

[0035] Specifically, the detection device of this utility model mainly includes two parts: a detection component 1 and a walking component 2. As shown in the attached diagram. Figure 1 As shown, the detection component 1 consists of a toothed ring 11 and a detection element 12. The diameter of the toothed ring 11 matches the gas pipeline to be detected, allowing the toothed ring 11 to be fitted over the gas pipeline. The detection element 12 is mounted on the toothed ring 11, with its detection direction facing the inside of the toothed ring 11. That is, when the toothed ring 11 is fitted over the gas pipeline, the detection direction of the detection element 12 faces the gas pipeline. The reason for using the toothed ring 11 to mount the detection element 12 is to achieve comprehensive coverage of all locations on the gas pipeline in conjunction with the traveling component 2.

[0036] Specifically, the traveling component 2 includes a traveling mechanism 21 and a connecting mechanism 22 disposed in the traveling cabinet. The detection component 1 is connected to the connecting cabinet, so that the detection component 1 can detect different positions in the axial direction of the gas pipeline as the traveling cabinet moves. In addition, the connecting mechanism 22 forms an installation structure for the gear ring 11 with the gear 222 through the assembly groove 221. That is, the gear 222 is disposed in the assembly groove 221, which is constructed as a channel, so that the gear ring 11 passes through the assembly gap between the tooth surface of the gear 222 and the groove wall of the assembly groove 221. In this way, the gear ring 11 and the gear 222 mesh with each other, and the gear ring 11 can rotate based on the meshing structure with the gear 222. That is, it can rotate along the axial direction of the gas pipeline to adjust the position of the detection element 12, thereby detecting different positions in the circumferential direction of the gas pipeline.

[0037] Therefore, based on the structural design of this utility model, by utilizing the cooperation of the toothed rings of the walking component and the detection component, the position of the detection element can be adjusted in the axial and circumferential directions of the gas pipeline, thereby achieving full coverage of all positions of the gas pipeline by the detection element, which can ensure the comprehensiveness and accuracy of the detection.

[0038] In one embodiment, the detection element 12 includes an adjusting screw 121 that passes radially through the gear ring 11, and a detection head 122 is installed at one end of the adjusting screw 121 corresponding to the radial inner side of the gear ring 11.

[0039] Specifically, as shown in the attached diagram. Figure 4 As shown, the detection element 12 is configured to be adjustable relative to the gear ring 11. Specifically, the detection element 12 includes an adjusting screw 121 threadedly engaged with the gear ring 11 and a detection head 122 disposed at one end inside the adjusting screw 121. The adjusting screw 121 passes radially through the gear ring 11, and the distance between the detection head 122 and the gas pipeline can be adjusted radially by rotation based on the threaded engagement structure to meet different needs. Depending on the detection requirements, the detection head 122 can be configured as a gas sensor for detecting gas leaks or a flaw detection scanning head for the pipeline itself.

[0040] In one embodiment, the gear ring 11 is constructed as a semi-circular arc, and detection elements 12 are respectively provided at both ends of the semi-circular gear ring 11.

[0041] Specifically, as shown in the attached diagram. Figure 1 As shown, the toothed ring 11 is designed in a semi-circular arc shape to balance comprehensive detection with ease of assembly and disassembly. Firstly, detection elements 12 are installed at both ends of the semi-circular toothed ring 11, allowing the toothed ring 11 to completely cover the gas pipeline circumferentially by rotating 180° in both directions. Secondly, the semi-circular toothed ring 11 can be fitted radially around the gas pipeline, facilitating easy assembly and disassembly of the toothed ring relative to the gas pipeline.

[0042] In one embodiment, the connecting mechanism 22 further includes a connecting rod 223, one end of which is fixed to the walking mechanism 21 and the other end is provided with an assembly groove 221, which extends through the end of the connecting rod 223 in a direction perpendicular to the axis of the connecting rod 223.

[0043] Specifically, as shown in the attached diagram. Figure 1 As shown, the main body of the connecting mechanism 22 is the connecting rod 223, the assembly groove 221 is constructed at one end of the connecting rod 223, the through direction of the assembly groove 221 is perpendicular to the axial direction of the connecting rod 223, and the other end of the connecting rod 223 is fixedly connected to the shaped cabinet.

[0044] In one embodiment, a turntable 224 coaxial with the gear 222 is provided on the end face of the connecting rod 223. A limiting rod 2241 extending radially is provided on the outer circumferential surface of the turntable 224. A limiting member 225 cooperating with the limiting rod 2241 is also provided on the end face of the connecting rod 223. The limiting member 225 can lock or unlock the limiting rod 2241 in the rotation direction of the turntable 224.

[0045] Specifically, as shown in the figure Figure 1 and Figure 3 As shown, a turntable 224 is provided on the end face of the connecting rod 223. The turntable 224 is coaxial with the gear 222, meaning that one end of the shaft containing the gear 222 extends out of the mounting groove 221 for the turntable 224 to be installed. In this way, the turntable 224 and the gear 222 can rotate synchronously. A limit rod 2241 is fixed on the circumferential surface of the turntable 224. The limit rod 2241 can engage with the limit member 225 on the end face of the connecting rod 223. That is, the limit member 225 can lock or unlock the limit rod 2241 in the rotation direction of the turntable 224. In this way, the engagement state of the limit member 225 and the limit rod 2241 can control the rotation state of the gear 222 through the turntable 224. The rotation of the gear 222 can be locked or unlocked as needed, thereby locking or unlocking the rotation of the gear ring 11 as needed.

[0046] In one embodiment, the limiting member 225 includes a limiting groove 2251 formed on the end face of the connecting rod 223, a limiting block 2252 disposed in the limiting groove 2251, and an elastic member 2253 disposed between the limiting block 2252 and the bottom of the limiting groove 2251. The limiting block 2252 includes two limiting portions spaced apart from each other. The limiting rod 2241 can be engaged between the portions of the two limiting portions that extend out of the limiting groove 2251, and the limiting block 2252 can be completely retracted into the limiting groove 2251 when pressed.

[0047] Specifically, as shown in the attached diagram. Figure 3 As shown, the main body of the limiting member 225 is a limiting block 2252, which includes two spaced-apart limiting parts. When the limiting rod 2241 is engaged between the two limiting parts, the rotation of the limiting rod 2241 can be restricted, thereby restricting the rotation of the turntable 224. To achieve this effect, in the structural design, the limiting block 2252 is placed in the limiting groove 2251 on the end face of the connecting rod 223, and an elastic element 2253 is provided between the limiting block 2252 and the bottom of the limiting groove 2251. In its natural state, due to the elastic force of the elastic element 2253, the limiting block 2252 partially extends out of the limiting groove 2251, so that the limiting rod 2241 can be engaged between the two limiting parts of the limiting block 2252, thereby locking the limiting rod 2241, and thus locking the gear 222 and the gear ring 11. When it is necessary to unlock the gear 222 and the gear ring 11, press the limiting block 2252 into the limiting groove 2251 to compress the elastic element 2253, so that the limiting block 2252 is completely retracted into the limiting groove 2251. In this way, the limiting part and the limiting rod 2241 are separated from each other, thereby unlocking the limiting rod 2241.

[0048] In one embodiment, the walking mechanism 21 includes a frame 211, a connecting mechanism 22 fixed to the frame 211, and two opposing walking wheels 212 are provided on the frame 211. The two walking wheels 212 can respectively clamp onto both sides of the gas pipeline, and at least one of the walking wheels 212 is connected to a drive motor 213.

[0049] Specifically, as shown in the attached diagram. Figure 1 and Figure 2 As shown, the main body of the walking mechanism 21 is a frame 211, on which two opposing walking wheels 212 are mounted. The walking wheels 212 are preferably constructed in an hourglass shape with larger diameters at both ends and a smaller diameter in the middle, allowing them to grip the gas pipeline from both sides. At least one of the walking wheels 212 is equipped with a drive motor 213 to provide the power for movement. Furthermore, the rotation of the gear ring 11 in the circumferential direction of the gas pipeline can be manually driven.

[0050] In one embodiment, the frame 211 includes a telescopic rod 2111 and two mounting frames 2112 connected by the telescopic rod 2111. Two wheels 212 are respectively mounted on the two mounting frames 2112, and a spacing adjustment member 214 is provided between the two mounting frames 2112.

[0051] Specifically, as shown in the attached diagram. Figure 1 and Figure 2 As shown, the frame 211 includes two mounting brackets 2112, a telescopic rod 2111 connected between the two mounting brackets 2112, and a spacing adjustment component 214. One end of the connecting rod 223 of the connecting mechanism 22 is vertically connected to the middle of the telescopic rod 2111. The spacing adjustment component 214 is used to adjust the distance between the two mounting brackets 2112, so as to facilitate the assembly and disassembly of the frame 211 relative to the gas pipeline and to accommodate gas pipelines of different diameters within a certain range. The telescopic rod 2111 can extend and retract in coordination with the spacing adjustment component 214 to adjust the distance between the two mounting brackets 2112.

[0052] In one embodiment, the spacing adjustment member 214 includes two threaded rods 2141 with opposite thread directions. The ends of the two threaded rods 2141 that are far apart from each other are respectively fixed to the corresponding mounting brackets 2112, and the ends of the two threaded rods 2141 that are close to each other are threadedly engaged with the same threaded sleeve 2142.

[0053] Specifically, as shown in the attached diagram. Figure 2As shown, the two threaded rods 2141 of the spacing adjustment component 214 are fixed to the corresponding mounting brackets 2112 respectively. The ends of the two threaded rods 2141 that are close to each other are threadedly engaged with the two ends of the threaded sleeve 2142. Since the thread directions of the two threaded rods 2141 are opposite, the two threaded rods 2141 can be moved closer or further apart by rotating the threaded sleeve 2142, thereby adjusting the spacing between the two mounting brackets 2112.
