Description

Technical Field

[0001] This utility model relates to the field of drainage pipeline inspection technology, specifically to an urban drainage pipeline inspection device. Background Technology

[0002] Drainage pipes refer to the systems of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. Urban drainage pipes are usually underground, and over time, solid waste accumulates inside, causing blockages. Regular dredging is necessary. Due to the complex internal environment of the pipes, detection devices are required to obtain images, determine the cause of the blockage, and then develop a reasonable dredging plan.

[0003] When inspecting vertical sections of urban drainage pipelines, wireless inspection equipment is mostly used for image acquisition. However, due to the long downward extension of some pipelines, the wireless inspection equipment may experience signal instability or interruption during image acquisition, affecting the pipeline inspection efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an urban drainage pipeline testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an urban drainage pipeline inspection device, comprising a housing, a support installed inside the housing, an operation screen provided on one side of the housing, the support being a U-shaped component, a retractor installed at the bottom of the support, a top rod provided at the bottom of the housing, a first inner rod sleeved inside the top rod, a second inner rod sleeved inside the first inner rod, a wire group provided on the outer surface of the retractor, one end of the wire group extending from the outer surface of the retractor to one side of the retractor and connecting to the operation screen, the other end of the wire group extending through the housing to the bottom of the second inner rod, and a detection probe being connected to the bottom of the wire group and the bottom of the second inner rod.

[0006] Preferably, the outer surface of the top rod is provided with a collar, and three extension frames are equidistantly arranged on the circumferential surface of the collar. Each of the three extension frames is hinged with a support leg. When the urban drainage pipeline inspection equipment is placed on top of the pipeline, the three support legs are opened so that the bottom of the three support legs contacts the ground to support the top rod, so that the top rod can be vertically inserted into the urban drainage pipeline without the need for manual removal of the equipment.

[0007] Preferably, a movable clamp is provided on the outer surface of the top rod below the collar. Three adjusting rods are circumferentially arranged on the circumferential surface of the movable clamp. The bottom of the three adjusting rods is respectively hinged to the corresponding support leg. When the support leg needs to be opened, first turn the screw of the movable clamp to loosen the top rod. Then press down on the movable clamp. The movable clamp pushes the top of the adjusting rod, so that the hinge position between the adjusting rod and the support leg is pushed, causing the support leg to open. When the support leg is opened to a certain angle, turn the screw of the movable clamp to lock the top rod and support the support leg, ensuring that the opened support leg will not close.

[0008] Preferably, a counterweight is provided inside the second inner rod near the detection probe. The counterweight increases the weight at the bottom of the second inner rod. When the top rod is inserted into the pipe, the second inner rod can extend downward under the influence of the weight of the counterweight when the retractor unwinds the wire, thereby driving the detection probe to extend into the pipe.

[0009] Preferably, a drive motor is provided on one side of the retractor, and the drive motor contains a reducer. The drive motor drives the retractor to rotate for unwinding or winding operations.

[0010] Preferably, the wiring harness consists of a waterproof layer, a reinforcing layer, and a signal line. The signal line is located in the middle position, wrapped with a reinforcing layer, and then wrapped with a waterproof layer. The signal line is used to transmit image information of the inside of the drainage pipe collected by the detection probe. The reinforcing layer is made of carbon fiber tape, which has extremely high strength and rigidity. The waterproof layer is made of waterproof adhesive, forming a protective layer outside the reinforcing layer to prevent the signal line from absorbing water molecules and causing a short circuit.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This urban drainage pipeline inspection equipment uses a cable assembly with a waterproof layer, a reinforcement layer, and a signal line on the outer surface of the retractor, which works in conjunction with the top rod, the first inner rod, and the second inner rod. During urban drainage pipeline inspection, the first and second inner rods can extend into the pipeline from inside the top rod, allowing the inspection probe to detect the internal condition of the pipeline. The signal is transmitted directly through the cable assembly, which is more stable than radio transmission and will not cause signal interruption, thus improving inspection efficiency.

[0013] 2. This urban drainage pipeline inspection equipment features expandable or retractable support legs, making it easy to place and retrieve. It is simple to operate and can quickly perform pipeline inspections. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 5As shown, this embodiment of an urban drainage pipeline inspection device includes a housing 1, with a bracket 8 installed inside the housing 1. An operation screen 2 is located on one side of the housing 1, containing a controller for controlling a drive motor 9. The bracket 8 is a U-shaped component, and a retractor 11 is installed at the bottom of the bracket 8. The retractor 11 is rotatably connected to the bottom of the bracket 8 and can rotate. A top rod 3 is located at the bottom end of the housing 1, with a first inner rod 14 sleeved inside the top rod 3. A second inner rod 15 is sleeved inside the first inner rod 14. A wire group 10 is provided on the outer surface of the retractor 11, with one end of the wire group 10 extending from the outer surface of the retractor 11. One side of the cable group 11 is connected to the operation screen 2 to extend the detection length. The other end of the cable group 10 extends through the housing 1 to the bottom of the second inner rod 15. The bottom of the cable group 10 and the bottom of the second inner rod 15 are connected to the detection probe 7. The first inner rod 14 can extend out of the top rod 3, and the second inner rod 15 can extend out of the first inner rod 14, driving the detection probe 7 to extend into the depth of the pipe to collect image information. The detection probe 7 is equipped with a supplementary light to provide illumination in the dark environment of the pipe. The image information collected by the detection probe 7 is transmitted to the operation screen 2 through the cable group 10 for storage. The inspection personnel can understand the internal condition of the drainage pipe through the collected image information.

[0023] Specifically, the outer surface of the top rod 3 is provided with a collar 4, and three extension frames 12 are equidistantly arranged on the circumferential surface of the collar 4. The three extension frames 12 are all hinged to the inside of the support legs 5. When the urban drainage pipe detection equipment is placed on the top of the pipe, the three support legs 5 are opened so that the bottom of the three support legs 5 contacts the ground to support the top rod 3, so that the top rod 3 can be vertically inserted into the urban drainage pipe without the need for manual removal of the equipment.

[0024] Furthermore, a movable clamp 6 is provided on the outer surface of the top rod 3 below the collar 4. Three adjusting rods 13 are arranged circumferentially on the circumferential surface of the movable clamp 6. The bottom of the three adjusting rods 13 are respectively hinged to the corresponding support legs 5. When it is necessary to open the support legs 5, first turn the screw of the movable clamp 6 to loosen the top rod 3, and then press down on the movable clamp 6. The movable clamp 6 pushes the top of the adjusting rod 13, so that the hinge position between the adjusting rod 13 and the support leg 5 is pushed, causing the support leg 5 to open. When the support leg 5 is opened to a certain angle, turn the screw of the movable clamp 6 to lock the top rod 3, support the support leg 5, and ensure that the opened support leg 5 will not close.

[0025] Furthermore, a counterweight 16 is provided inside the second inner rod 15 near the detection probe 7. The counterweight 16 increases the weight at the bottom of the second inner rod 15. When the top rod 3 is inserted into the pipe, the retractor 11 unwinds the wire group 10, and the second inner rod 15 can extend downward under the influence of the weight of the counterweight 16, so as to drive the detection probe 7 into the pipe.

[0026] Furthermore, a drive motor 9 is provided on one side of the retractor 11. The drive motor 9 contains a reducer and drives the retractor 11 to rotate for unwinding or winding operations.

[0027] Furthermore, the wiring harness 10 consists of a waterproof layer 101, a reinforcing layer 102, and a signal line 103. The signal line 103 is located in the middle and is wrapped with the reinforcing layer 102. The reinforcing layer 102 is wrapped with the waterproof layer 101. The signal line 103 is used to transmit the image information inside the drainage pipe collected by the detection probe 7. The reinforcing layer 102 is made of carbon fiber tape, which has extremely high strength and rigidity. The waterproof layer 101 is made of waterproof adhesive and forms a protective layer on the outside of the reinforcing layer 102 to prevent the signal line 103 from absorbing water molecules and causing a short circuit.

[0028] The usage method of this embodiment is as follows: When using the urban drainage pipe inspection equipment, first turn the screw of the movable clamp 6 to loosen the top rod 3, then press down on the movable clamp 6. The movable clamp 6 pushes the top of the adjusting rod 13, causing the hinged position between the adjusting rod 13 and the support leg 5 to be pushed, thus opening the support leg 5. When the support leg 5 is opened to a certain angle, turn the screw of the movable clamp 6 to lock the top rod 3, supporting the support leg 5 and ensuring that the opened support leg 5 will not close. Then, insert the bottom of the top rod 3 into the top of the pipe to be inspected, so that the three support legs 5 are supported on the ground. Then, operate... When the detection probe 7 is turned on, the inside of the pipe is illuminated by the supplementary light contained in the detection probe 7. This allows the probe to collect image information of the environment inside the pipe and transmit it to the operation screen 2 for storage via the cable group 10. If the vertical section of the pipe is long, the drive motor 9 can be turned on through the operation screen 2. The drive motor 9 causes the retractor 11 to unwind. At this time, the bottom of the cable group 10 on the outer surface of the retractor 11 extends downward. Through the counterweight block 16 set inside the second inner rod 15, the second inner rod 15 and the first inner rod 14 are driven to extend into the pipe, thereby driving the detection probe 7 to detect the inside of the pipe.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
