Description

Technical Field

[0001] The present invention relates to the technical field of drain pipe detection, and particularly to a detection device for building water supply and drainage pipes. Background Technique

[0002] Water supply and drainage pipes are key components of the internal drainage system of buildings. Regular inspection can ensure that the drainage pipes are unobstructed. If problems such as blockage or leakage occur, it may lead to water disasters and cause serious damage to the building. By inspecting the drainage pipes, potential problems can be detected and repaired in a timely manner to prevent water disasters and damage.

[0003] Generally, when detecting whether there is blockage, corrosion or cracks inside the drainage pipe, it is basically through a walking device with camera detection to conduct real-time shooting and detection inside the pipe. When detecting the in-use drainage pipe, due to the presence of a large amount of sludge or foreign objects inside the drainage pipe, it is easy to cause the camera area to be attached with sludge during the walking detection. Generally, it is necessary for the staff to frequently stop the machine and retract this device, and then frequently wipe and clean the surface of the camera to reduce the influence of sludge attachment on detection. This detection method greatly reduces the detection efficiency of subsequent detection due to the need to frequently stop the detection and retract for cleaning. Summary of the Invention

[0012] Further, the lifting assembly includes a hollow cylinder II rotatably connected to the side of the sliding plate away from the electric push rod. A plurality of rectangular grooves are formed on the outer surface of the hollow cylinder II. Two sliding shafts are slidably connected inside the hollow cylinder II. A plurality of inclined grooves are formed on the outer surface of the sliding shaft.

[0013] Further, the pushing assembly includes two rotating plates arranged inside the hollow box.

[0014] Further, the transmission assembly includes a serrated plate meshed with the outer surfaces of a plurality of the serrated blocks. The side wall of the serrated plate is slidably connected to the side wall of the camera; Wherein, one side of the serrated plate away from the elastic sleeve is fixedly connected with a spring rod. One end of the spring rod away from the serrated plate penetrates through the side wall of the mounting plate and extends to the outside of the mounting plate.

[0015] The present invention has the following beneficial effects: 1. In the present invention, when sludge adheres to the camera and causes the image to be unclear, the electric push rod will drive the transparent belt to slide backward through the sliding plate and the hollow cylinder II, so that the adsorption end of the hollow piston rod adsorbs to the side wall of the transparent belt. Under the continuous adsorption of the suction pump, it will directly act on the hollow piston rod, and drive the transparent belt to rotate cyclically under the action of the adsorption force. When the transparent belt rotates cyclically, the sludge attached to the transparent belt can be moved out of the shooting range of the camera. At the same time, the cleaning section on the transparent belt will be replaced. At the same time, the side wall of the hollow box will clean the sludge attached to the transparent belt, ensuring that the detection area of the camera is always in a clean area, reducing the situation that this device needs to be frequently stopped and retracted for cleaning due to the attachment of soil in the detection area during walking detection, and reducing the time for detection interruption due to frequent stops and cleaning, thereby improving the detection efficiency and convenience of the detection work.

[0016] 2. In the present invention, when the transparent belt drives the two hollow cylinders II to rotate synchronously, the stepped plate on the fixed plate will drive the sliding shaft to slide up and down reciprocally under the block of the fixed frame during rotation. When the sliding shaft slides upward, it will extrude the spring block outward through the inclined groove on its surface and drive the spring block to slide upward at the same time. When the spring block slides outward, it will squeeze the transparent belt to make the tension of the transparent belt increase and be in a taut state. When the spring block slides upward, it can slide from the side wall of the transparent belt to its edge, reducing the situation that the transparent belt rotates with uneven tension or the edge of the transparent belt generates large friction with the side wall of the mounting plate during rotation, resulting in uneven force and friction on the transparent belt during rotation, and thus causing creases. This design can reduce the generation of creases and avoid the situation that the flatness of the transparent belt changes due to creases during subsequent camera detection, resulting in blurred or uneven brightness of the camera image. It can improve the clarity of the camera detection field of view while also improving the clarity and accuracy of the detected image data.

[0017] 3. In the present invention, when the sliding plate slides backward, it squeezes both ends of the elastic sleeve to cause a shrinking deformation. When the elastic sleeve deforms, it will closely contact the side wall of the transparent belt. At the same time, the rotation of the fixed plate will periodically squeeze the spring rod through multiple short rods and slide on the serrated block on the elastic sleeve. When the short rod disengages from the spring rod, the spring rod will drive the elastic sleeve and the transparent belt to rotate, enhancing the rotational force of the transparent belt and reducing the situation that the transparent belt is blocked, interrupted, discontinuous or jumps between the hollow piston rod due to the increased tension of the transparent belt under the extrusion and sliding of the spring blocks at both ends. Thus, it can avoid the problem that the hollow piston rod cannot connect to drive the transparent belt to rotate and the sludge on the transparent belt is not easily rotated and replaced by the cleaning section on the transparent belt. At the same time, it can avoid the situation that the transparent belt does not rotate at the expected speed and mud or foreign objects continue to adhere in front of the camera. While enhancing the cleaning effect of the imaging area, it can also enhance the stability of the transparent belt rotation cleaning, and further enhance the detection effect.

[0018] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The connection component 11 includes a connecting rod 111 rotatably connected to the top of the main body 1, and a traction plate 112 is rotatably connected to the outer surface of the connecting rod 111; The flipping member includes a hollow box 1201 rotatably connected to the side of the reversing frame 101 away from the main body 1. The camera 4 is installed at the front end of the hollow box 1201. The side of the hollow box 1201 close to the reversing frame 101 is rotatably connected to the side of the connecting rod 111, and hollow plates 122 are bolted to both sides of the hollow box 1201; The rotating assembly 12 includes a turning plate 121 hinged to the top of the hollow box 1201, and two mounting plates 123 are detachably connected inside the hollow box 1201; Among them, two fixing frames 124 are arranged inside the hollow plate 122. One side of the bottom fixing frame 124 close to the hollow box 1201 is fixedly connected to the side wall of the hollow box 1201, and one side of the top fixing frame 124 close to the mounting plate 123 is fixedly connected to the side wall of the mounting plate 123. First, connect the signal transmission line to the main body 1, then connect it to the traction plate 112 through the traction rope, and then place this device inside the drainage pipe to be detected. After that, control this device to move through the controller 102, and at the same time, control the driving motor 103 to drive the reversing frame 101 to rotate through the controller 102 and drive the rotating assembly 12 to move through the reversing frame 101.

[0028] The suction assembly 21 includes a suction pump 211 fixedly connected to the side wall of the hollow box 1201. The output end of the suction pump 211 is fixedly connected to a communication pipe 212. One end of the communication pipe 212 away from the suction pump 211 is fixedly connected to a hollow cylinder I 213. The side wall of the hollow cylinder I 213 is fixedly connected inside the hollow box 1201, and the suction pump 211 is electrically connected to the controller 102.

[0029] A hollow piston rod 214 is slidably connected inside the hollow cylinder I 213. A filter is installed at the adsorption end of the hollow piston rod 214. A return spring is fixedly connected to the outer surface of the hollow piston rod 214. One end of the return spring close to the hollow cylinder I 213 is fixedly connected to the side wall of the hollow cylinder I 213. An inclined plate 215 is fixedly connected to one side of the hollow cylinder I 213 close to the return spring; The moving assembly 22 includes an electric push rod 221 fixedly connected to the inner wall of the hollow box 1201 close to the main body 1. The output end of the electric push rod 221 is fixedly connected to a sliding plate 222. Two short shafts are fixedly connected to the top of the sliding plate 222, and the electric push rod 221 is electrically connected to the controller 102.

[0030] The lifting assembly 23 includes a hollow cylinder II 231 rotatably connected to the side of the sliding plate 222 away from the electric push rod 221. A plurality of rectangular grooves are formed on the outer surface of the hollow cylinder II 231. Two sliding shafts 232 are slidably connected inside the hollow cylinder II 231. A plurality of inclined grooves are formed on the outer surface of the sliding shafts 232. A transparent belt 235 is sleeved on the outer surfaces of the two hollow cylinders II 231 together; The spring member includes a tension spring 236 fixedly connected to one side of the sliding shaft 232 near the middle of the hollow cylinder II 231. The tension spring 236 is fixedly connected to the inner wall of the hollow cylinder II 231. A spring block 234 is fixedly connected to the side of the rectangular groove away from the middle of the hollow cylinder II 231. Wherein, one side of the sliding shaft 232 away from the middle of the hollow cylinder II 231 is fixedly connected with a fixing plate 233. A plurality of stepped plates are fixedly connected to the side of the fixing plate 233 close to the hollow cylinder II 231. A plurality of short rods are fixedly connected to the outer surface of one of the fixing plates 233.

[0031] The two hollow cylinders II 231 are synchronously rotated by the transparent belt 235. While the hollow cylinder II 231 is rotating, the stepped plates on the fixing plate 233 will drive the sliding shaft 232 to slide up and down reciprocally under the block of the fixed frame 124.

[0032] When sludge adheres to the camera 4 and causes the image to be unclear, the electric push rod 221 will drive the transparent belt 235 to slide backward through the sliding plate 222 and the hollow cylinder II 231, that is, in the direction close to the reversing frame 101, and make the adsorption end of the hollow piston rod 214 adsorb to the side wall of the transparent belt 235.

[0033] When the spring block 234 slides outward, it will squeeze the transparent belt 235 to make the tension of the transparent belt 235 become larger and be in a taut state. At the same time, when the spring block 234 slides upward, it can slide on the side wall of the transparent belt 235 towards its edge, which can reduce the situation that the transparent belt 235 is subjected to uneven forces and frictions during rotation due to changes in tension or large friction between the edge of the transparent belt 235 and the side wall of the mounting plate 123 during rotation, resulting in creases.

[0034] The pushing component 31 includes two rotating plates 311 arranged inside the hollow box 1201. A push rod 312 is rotatably connected to the side of the rotating plate 311 away from the hollow cylinder II 231. An elastic sleeve 313 is slidably connected between the two push rods 312. A plurality of serrated blocks are fixedly connected to the top of the elastic sleeve 313. Wherein, a vertical rod is fixedly connected to the top of the rotating plate 311, and the top of the vertical rod is rotatably connected to the side wall of the mounting plate 123.

[0035] When the sliding plate 222 slides backward, it will push the side wall of the rotating plate 311 through the two short shafts at the top and squeeze the two ends of the elastic sleeve 313 through the push rod 312. After the two ends of the elastic sleeve 313 are squeezed, a shrinking deformation will occur. When the elastic sleeve 313 deforms, it will be in close contact with the side wall of the transparent belt 235.

[0036] The transmission assembly 32 includes a serrated plate 321 meshed and connected to the outer surfaces of a plurality of the serrated blocks, and the side wall of the serrated plate 321 is slidably connected to the side wall of the camera 4; Wherein, a spring rod 322 is fixedly connected to the side of the serrated plate 321 away from the elastic sleeve 313. One end of the spring rod 322 away from the serrated plate 321 penetrates through the side wall of the mounting plate 123 and extends to the outside of the mounting plate 123. When the fixing plate 233 rotates, it will periodically squeeze the spring rod 322 through a plurality of short rods. After the spring rod 322 is squeezed, it will slide on the serrated blocks on the elastic sleeve 313. When the short rod is disengaged from the spring rod 322, the spring rod 322 will reset under the elastic force of the spring.

[0037] During use, first connect the signal transmission line to the main body 1, then connect it to the traction plate 112 through the traction rope, place this device inside the drainage pipe to be detected, then control the movement of this device through the controller 102, and at the same time control the driving motor 103 through the controller 102 to drive the reverse frame 101 to rotate and drive the rotating assembly 12 to move through the reverse frame 101, so that the camera 4 can take pictures and detect the inside of the drainage pipe. At this time, the camera 4 will transmit the data of the shooting and detection to the background to complete the detection.

[0038] When the device starts the suction pump 211 during walking detection, and then during walking, when sludge adheres to the camera 4 and causes the image to become unclear, the electric push rod 221 is started. When the electric push rod 221 works, it will drive the sliding plate 222 and the hollow cylinders II 231 at both ends of the sliding plate 222, and then drive the transparent belt 235 to slide backward. When the hollow cylinder II 231 drives the transparent belt 235 to slide backward, the adsorption end of the hollow piston rod 214 will adsorb to the side wall of the transparent belt 235. At this time, a sealed space will be formed between the hollow piston rod 214 and the hollow cylinder I 213. After that, when the suction pump 211 continuously sucks inside the hollow cylinder I 213, the suction force generated by the suction pump 211 will directly act on the hollow piston rod 214, causing the hollow piston rod 214 to slide inside the hollow cylinder I 213 under the action of the suction force. When the hollow piston rod 214 slides, it will drive the transparent belt 235 and the sludge attached to the transparent belt 235 to rotate cyclically. When the transparent belt 235 rotates cyclically, the sludge attached to the transparent belt 235 can be moved out of the shooting range of the camera 4, and at the same time, the cleaning section on the transparent belt 235 will be replaced. The side wall of the hollow box 1201 will clean the sludge attached to the transparent belt 235, ensuring that the detection area of the camera 4 is always in a clean area, reducing the situation that the device needs to be frequently stopped and retracted for cleaning during walking detection due to the attachment of soil in the detection area, and reducing the time for detection to be interrupted due to frequent stops and cleaning, thereby improving the detection efficiency and convenience of the detection work.

[0039] When the hollow piston rod 214 moves to the end of the hollow cylinder I 213 under the action of the suction force, the inclined plate 215 on the hollow cylinder I 213 will be inserted between the hollow piston rod 214 and the transparent belt 235 when the hollow piston rod 214 drives the transparent belt 235 to slide, so that the hollow piston rod 214 no longer adsorbs the transparent belt 235.

[0040] When the hollow piston rod 214 is driven by the suction force of the suction pump 211 to drive the transparent belt 235 to rotate on the two hollow cylinders II 231, the rotation of the transparent belt 235 will drive the two hollow cylinders II 231 to rotate synchronously. When the hollow cylinder II 231 rotates, it will drive the two sliding shafts 232 to rotate synchronously. When the sliding shaft 232 rotates, the stepped plate on the fixed plate 233 will be blocked by the fixed frame 124 during rotation, causing it to drive the sliding shaft 232 to slide up and down reciprocally. When the sliding shaft 232 slides upward, it will extrude the spring block 234 outward through the inclined groove on its surface. At the same time, the spring block 234 will also slide upward synchronously with the sliding of the sliding shaft 232 under the extrusion of the inclined groove. When the spring block 234 slides outward, it will squeeze the transparent belt 235, making the tension of the transparent belt 235 increase and thus enter a taut state. Moreover, when the spring block 234 slides upward, it can slide from the side wall of the transparent belt 235 towards its edge, thereby reducing the situation where the transparent belt 235 is subjected to uneven forces and friction during rotation due to changes in tension or large friction between the edge of the transparent belt 235 and the side wall of the mounting plate 123 during rotation, resulting in creases. This design can reduce the generation of creases and avoid subsequent changes in the flatness of the transparent belt 235 due to creases during camera detection, which may lead to blurred or uneven brightness of the camera image. It can improve the clarity of the detection field of view of the camera 4 while also improving the clarity and accuracy of the detected image data.

[0041] When the sliding plate 222 slides backward, that is, in the direction close to the reversing frame 101, the sliding of the sliding plate 222 will push the side wall of the rotating plate 311 through two short shafts at its top. After the side wall of the rotating plate 311 is pushed, it will squeeze both ends of the elastic sleeve 313 through the push rod 312. When both ends of the elastic sleeve 313 are squeezed, a contracting deformation will occur. When the elastic sleeve 313 deforms, its side wall will be in close contact with the side wall of the transparent belt 235. At the same time, when the fixing plate 233 slides backward with the sliding plate 222, multiple short rods on the fixing plate 233 will contact the spring rod 322. When the rotation of the transparent belt 235 drives the fixing plate 233 to rotate, the rotation of the fixing plate 233 will periodically squeeze the spring rod 322 through multiple short rods. When the spring rod 322 is squeezed, it will slide on the serrated block on the elastic sleeve 313. When the short rod disengages from the spring rod 322, the spring rod 322 will reset under the elastic force of the spring on its surface. When the serrated plate 321 resets, it will drive the elastic sleeve 313 to rotate through the meshing serrated block. When the elastic sleeve 313 rotates, it will drive the transparent belt 235 to rotate through the fit between the elastic sleeve 313 and the side wall of the transparent belt 235, enhancing the rotational force of the transparent belt 235 and reducing the situation where the transparent belt 235 is blocked, interrupted, discontinuous or jumps due to the increased tension of the transparent belt 235 under the extrusion and sliding of the spring blocks 234 at both ends, thus avoiding the problem that the hollow piston rod 214 cannot connect to drive the transparent belt 235 to rotate and the sludge on the transparent belt 235 is not easily rotated and replaced by the cleaning section on the transparent belt 235. At the same time, it avoids the situation where the transparent belt 235 does not rotate at the expected speed and mud or foreign objects continue to adhere in front of the camera 4. While enhancing the cleaning effect of the imaging area, it can also enhance the stability of the rotation cleaning of the transparent belt 235, thereby enhancing the detection effect.
