Two obstacle-crossing devices are provided, located on both sides of the mobile device. The lower device includes a lower base 201 and a positioning mechanism. The obstacle-crossing device includes a side column 301, which is fixedly installed with the lower base 201.

[0030] like Figures 3-5 As shown, the walking mechanism includes a mobile motor 102 fixedly mounted on the upper seat 101, a motor gear 103 fixedly mounted on the motor shaft of the mobile motor 102, three actuating wheels 105 rotatably mounted on the upper seat 101, and walking gears 106 fixedly mounted on the actuating wheels 105. A transmission belt 107 is wound around the motor gear 103 and the three walking gears 106.

[0031] like Figures 3-5 As shown, three traveling wheels 108 are rotatably mounted on the upper seat 101. The traveling wheels 108 are located below the actuating wheel 105. The outer wall of the traveling wheels 108 is provided with teeth. The traveling wheels 108 mesh with the actuating wheel 105 through the teeth on the outer wall. The traveling wheels 108 are in contact with the outer wall of the pipe 5.

[0032] like Figures 3-5As shown, an upper detector 104 is installed on the upper base 101, and a lower detector 208 is installed on the lower base 201. The upper detector 104 and the lower detector 208 can use existing CCTV pipeline inspection robots, pipeline detectors, ultrasonic thickness gauges, and leak detectors to detect pipeline faults. This is existing technology and will not be described in detail. The upper base 101 is provided with four insertion holes 112.

[0033] like Figures 3-5 As shown, four corner posts 109 are provided on the upper seat 101. A docking post 110 is slidably installed inside the corner posts 109. The top of the docking post 110 is hemispherical. An inner spring 111 is provided behind the docking post 110 and the corner posts 109.

[0034] like Figures 6-8 As shown, the lower device includes three lower top columns 203 that are slidably mounted on the lower base 201.

The upper surface of the lower top block 204 is an arc surface.

[0035] like Figures 6-8 As shown, the lower base 201 is provided with three sliding grooves 209, and a lower wheel 202 is slidably installed in each set of sliding grooves 209. The lower wheel 202 can rotate in the sliding groove 209 and is in contact with the lower top block 204.

[0036] like Figures 6-8 As shown, the positioning mechanism includes a pedometer 207 and a beacon 206. The pedometer 207 is fixedly installed on the lower base 201, and the beacon 206 is fixedly installed inside the lower wheel 202 located in the middle of the lower base 201. The specific process of positioning using the beacon 206 and the pedometer 207 is prior art and will not be described in detail here.

[0037] The side column 301 and the cross frame 303 are fixedly connected. The cross frame 303 is connected to the upper seat 101 through the trapezoidal block 304. The upper seat 101 drives the lower seat 201 to move together through the side column 301. The lower wheel 202 is in contact with the pipe 5. The lower wheel 202 rotates to assist in the movement. The lower top spring 205 ensures that the lower wheel 202 is always in close contact with the pipe 5 when the lower seat 201 moves. The beacon 206 passes in front of the pedometer 207 once, and the pedometer 207 records once. With the help of the two upper detectors 104 and the lower detector 208, the location of the fault in the pipe 5 can be determined.

[0038] like Figure 9 , Figure 10 As shown, the obstacle-crossing device includes two rotating frames 302 rotatably mounted on the side column 301. A cross frame 303 is fixedly mounted on the side column 301. The rotating frames 302 are provided with six docking holes 306, which cooperate with the docking column 110.

[0039] like Figure 9 , Figure 10 As shown, a trapezoidal block 304 is slidably mounted on the crossbeam 303. The front of the trapezoidal block 304 has a slope. A retaining spring 305 is provided between the trapezoidal block 304 and the crossbeam 303. The trapezoidal block 304 forms a sliding fit with the insertion hole 112. The crossbeam 303 is connected by the insertion of the trapezoidal block 304 into the upper seat 101 and the engagement of the mating hole 306 and the mating post 110.

[0040] The working principle of the pipeline fault detection device disclosed in this utility model is as follows: When in use, the upper seat 101 is placed above the pipeline 5, and the three traveling wheels 108 are in contact with the pipeline 5. The moving motor 102 drives the motor gear 103 to rotate, which drives the three traveling gears 106 and the actuating wheel 105 to rotate through the transmission belt 107, thereby driving the three traveling wheels 108 to rotate, so that the upper seat 101 moves along the pipeline 5. The upper detector 104 and the lower detector 208 are used to detect the surface and interior of the pipeline 5. The upper seat 101 moves together with the lower seat 201 via the side column 301. The lower wheel 202 is in contact with the pipe 5. The rotation of the lower wheel 202 assists in the movement. The lower top spring 205 ensures that the lower wheel 202 is always in contact with the pipe 5 when the lower seat 201 moves. The beacon 206 passes in front of the pedometer 207 once, and the pedometer 207 records the step. With the help of the two upper detectors 104 and the lower detector 208, the location of the fault in the pipe 5 can be determined.When the fault detection device moves in front of the boom 4, the two rotating frames 302 in front first contact the boom 4. Under the action of the boom 4, the rotating frames 302 begin to rotate, and the docking hole 306, which originally cooperated with the docking post 110, disengages from the docking post 110. Then, the next docking hole 306 rotates to the docking post 110, causing the docking post 110 to descend first, compressing the inner spring 111. Subsequently, when the docking hole 306 is directly above the docking post 110, the inner spring 111 rebounds, causing the docking post 110 to insert into the docking hole 306. During this obstacle-crossing process... All four trapezoidal blocks 304 are located in the insertion holes 112, and the two rear rotating brackets 302 are engaged with the docking column 110, while the crossbeam 303 will not detach from the upper seat 101. Subsequently, the two front trapezoidal blocks 304 come into contact with the hanger 4. Under the action of the hanger 4 (there is a slope on the trapezoidal block 304; when the slope encounters the hanger 4, the hanger 4 contacts the slope on the trapezoidal block 304, but the hanger cannot move, so it pushes the trapezoidal block 304 outward, creating a force separation. The hanger 4 applies force in a direction perpendicular to the slope of the trapezoidal block 304, resulting in an outward force). The force pushes the trapezoidal block 304 outward, compressing the locking spring 305 and causing the trapezoidal block 304 to disengage from the insertion hole 112. After the trapezoidal block 304 passes the boom 4, the locking spring 305 rebounds, causing the trapezoidal block 304 to re-insert into the insertion hole 112. During this obstacle-crossing process, the two rear trapezoidal blocks 304 are both located in the insertion hole 112, and the four rotating frames 302 at the front and rear maintain cooperation with the docking column 110. The crossbeam 303 will not disengage from the upper seat 101. The rear trapezoidal blocks 304 and rotating frames 302 cross in the same way. When the lower wheel 202 moves to the hanger 4, it slides down the slide groove 209 under the action of the hanger 4, which compresses the lower top spring 205. After the lower wheel 202 passes the hanger 4, the lower top spring 205 rebounds, so that the lower wheel 202 re-fits with the pipe 5. Only one lower wheel 202 passes the hanger 4 at a time, while the other two lower wheels 202 remain in contact with the pipe 5. In the end, the fault detection device passes the hanger 4, so that the fault detection device can move along the entire pipe 5 and automatically detect the pipe 5.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope of the present utility model based on the technical solution and the inventive concept of the present utility model should be included within the protection scope of the present utility model.
