Through various technical means, such as sound detection, pressure monitoring, liquid detection, etc., pipeline leakage accidents can be effectively prevented. When a water supply pipeline leaks, water overflows under pressure and generates a kind of noise, which will spread along the pipeline to both sides. The device judges the leakage position through the sound.

Detailed implementation mode

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1:

[0030] As Figures 1-4 shown in the technical solution, the present invention provides the following technical solutions: To solve the problem of low assembly efficiency of the detection device, a clamping mechanism is disclosed:

[0031] It includes a first connecting seat 1. The bottom of the first connecting seat 1 is connected to a second connecting seat 2. Both the side surfaces of the first connecting seat 1 and the second connecting seat 2 are connected to support rods 3. The bottom of the support rod 3 is provided with rollers 4. Sound sensors 5 are connected inside both the first connecting seat 1 and the second connecting seat 2. A first rotating block 101 is fixed to the back of the first connecting seat 1, and a second rotating block 102 is fixed to the back of the second connecting seat 2. A telescopic groove 103 is opened in the front of the first connecting seat 1. A first spring 104 is connected inside the telescopic groove 103. The bottom end of the first spring 104 is connected to a sliding block 105. The sliding block 105 penetrates and slides inside the telescopic groove 103. An engaging groove 106 is opened at the top of the sliding block 105. A connecting block 107 is fixed to the front of the second connecting seat 2. A rotating block 108 is rotatably arranged inside the connecting block 107. An engaging block 109 is fixed to the inner side of the rotating block 108. A clamping mechanism for merging and connecting with the second connecting seat 2 is connected to the side surface of the first connecting seat 1. Fixed blocks 110 are fixed to both the side surfaces of the first connecting seat 1 and the second connecting seat 2. An adjusting mechanism for more stable contact with the pipeline is arranged inside the fixed block 110;

[0032] The first rotating block 101 and the second rotating block 102 are rotatably connected. The sliding block 105 and the second rotating block 102 form a telescopic structure through the first spring 104. The engaging groove 106 and the engaging block 109 are engaged. The rotating block 108 and the connecting block 107 are rotatably connected, and there are two groups of connecting blocks 107 that are centrosymmetric about the center of the sliding block 105. When the detection device is in use, move the first connecting seat 1 to the side of the pipeline. Pushing the second connecting seat 2 can drive the second rotating block 102 and the first rotating block 101 to rotate. When the second connecting seat 2 rotates to the side of the first connecting seat 1, it pushes the rotating block 108. When the rotating block 108 is pushed, it can rotate through the connecting block 107. When the rotating block 108 rotates, it can drive the engaging block 109 to rotate. When the inclined surface of the engaging block 109 rotates to the side of the sliding block 105, it can be extruded. When the sliding block 105 is extruded, it can slide through the telescopic groove 103. At the same time, the sliding block 105 can stretch the first spring 104. After the sliding block 105 stretches to a certain position, the engaging block 109 can be extruded into the engaging groove 106. At this time, the sliding block 105 can be reset under the pulling force of the first spring 104. When resetting, it can drive the engaging groove 106 and the engaging block 109 to be engaged and fixed. When the engaging block 109 is fixed, it can drive the first connecting seat 1 and the second connecting seat 2 to be connected to the surface of the pipeline. The sound sensor 5 inside the device can detect the leakage position of the pipeline through the signal transmitted by the leakage sound, which is convenient for the device to be quickly assembled and used.

[0033] Embodiment 2:

[0034] As Figure 5 and Figure 6 shown in the technical solution, the present invention provides the following technical solution: To solve the problem that the support rod of the detection device is not convenient to adjust and difficult to adapt to different pipelines, an adjustment mechanism is disclosed:

[0035] The adjusting mechanism includes a sliding groove 111, and the sliding groove 111 is opened at the top of the fixed block 110. A double-headed motor 112 is installed inside the sliding groove 111. Threaded rods 113 are fixed at both ends of the double-headed motor 112. A guiding block 114 is threadedly connected to the side of the threaded rod 113. The guiding block 114 slides inside the sliding groove 111. A first rotating shaft 115 is fixed to the top of the guiding block 114. A rotating rod 116 is rotatably connected inside the first rotating shaft 115. The left end of the rotating rod 116 is rotatably connected to a second rotating shaft 117, and the second rotating shaft 117 is fixed to the bottom of the support rod 3. A third rotating shaft 118 is fixed to the top of the fixed block 110. The support rod 3 is rotatably connected inside the third rotating shaft 118. A telescopic mechanism is provided at the end of the support rod 3. When the device is in use, the output end of the double-headed motor 112 can drive the two threaded rods 113 to rotate. When the threaded rods 113 rotate, they can drive the guiding block 114 to perform threaded sliding. When the guiding block 114 performs threaded sliding, it can push the first rotating shaft 115 to move. When the first rotating shaft 115 moves, the rotating rod 116 can push the second rotating shaft 117, and the rotating rod 116 can rotate through the second rotating shaft 117 and the first rotating shaft 115. When the rotating rod 116 rotates, it can push the support rod 3 to rotate inside the third rotating shaft 118. When the support rod 3 rotates, it can drive the roller 4 to rotate. The roller 4 can adjust to a suitable angle according to the size of the pipeline. Moreover, due to the inclined surface shape of the roller 4, it can better fit the wall surface of the pipeline, facilitating movement. At the same time, the two double-headed motors 112 save the cost of the device and facilitate the detection device to adapt to pipelines of different sizes.

[0036] Embodiment 3:

[0037] As Figure 5 shown in the technical solution, the present invention provides the following technical solution: To solve the problem of the low passability of the roller 4, a telescopic mechanism is disclosed:

[0038] The telescopic mechanism includes a guiding rod 119. The guiding rod 119 penetrates and slides inside the support rod 3. A roller 4 is fixed to the bottom end of the guiding rod 119. A second spring 120 is sleeved on the surface of the guiding rod 119. When the detection device moves on the pipe wall surface, when the roller 4 encounters a small obstacle, it can directly squeeze it. When the roller 4 squeezes, it can drive the guiding rod 119 to move. When the guiding rod 119 moves, it can slide through the support rod 3 painfully. And the roller 4 can drive the second spring 120 to squeeze the support rod 3. When the second spring 120 is squeezed, it can contract, thereby raising the moving range of the roller 4 and improving the passability of the detection device.
