[0002] Underground pipelines are pipes laid underground for the transportation of liquids, gases or loose solids. In ancient China, underground drainage pipes made of fired clay were already used. In the Ming Dynasty, when Beijing was the capital, bricks and stone strips were used extensively to build underground drainage pipes. The width was about 1 meter and the height was about 2 meters. There are many types of modern underground pipelines, including circular, elliptical, semi-elliptical, multi-center, oval, rectangular (single hole, double hole and multi-hole), horseshoe and other cross-sectional forms. They are built with materials such as steel, cast iron, concrete, reinforced concrete, prestressed concrete, brick, stone, asbestos cement, clay, plastic, fiberglass (reinforced plastic) and so on.

Four sets of wire reel casters 16 are evenly installed on the bottom of the wire reel box 15 and a flap bracket 17 is movably connected to the top. A lithium battery 18 is also provided at the tail of the wire reel box 15 and a push-pull handle 19 is installed at the front end. The wire winding mechanism includes a wire winding roller 20 built into the wire reel box 15 and a manual handle 21 installed on one side of the wire winding roller 20. A wiring head 22 is installed at one end of the wire winding roller 20. The wiring head 22 is connected to the cable 12 and a reciprocating shaft 23 is rotatably provided on one side. A driving motor 24 is installed at one end of the reciprocating shaft 23. A reciprocating structure 25 is movably provided on the reciprocating shaft 23 and a wire pressure wheel 26 is provided in parallel on the outside. The cable 12 passes through the reciprocating structure 25. The lithium battery 18 is also connected to a power switch 27, a jog button 28 and an emergency stop button 29.

[0024] Further improvement, such as Figure 2 As shown: the protection rod 11 is arranged in a ring shape outside the front camera 5. The protection rod 11 is made of steel material, which can achieve the purpose of protecting the front camera 5.

[0025] Further improvement, such as Figure 2 As shown: the lifting connecting rod 7 is composed of an electric push rod, which is arranged in an inclined shape and the end of the electric push rod is connected to the front high beam lamp 6. The front high beam lamp 6 is driven by the electric push rod to adjust its height.

[0026] Further improvement, such as Figure 1 As shown, two groups of wire stoppers 14 are arranged in parallel, and the cable 12 is inserted between the two groups of wire stoppers 14 to facilitate the guidance of the cable 12.

[0027] Further improvement, such as Figure 3 As shown: a charging socket 30 and a discharging socket 31 are respectively installed on the lithium battery 18, and the charging socket 30 is located below the discharging socket 31 for charging and discharging processing.

[0028] Further improvement, such as Figure 2 As shown: the tires 4 can be installed in four or six groups, and several groups of tires 4 have the same specifications and the same height, and can be selected according to needs.

[0029] Further improvement, such as Figure 4 As shown: the power output end of the driving motor 24 is connected to the reciprocating shaft 23, and the surface of the reciprocating shaft 23 is a threaded structure, which is designed to facilitate the reciprocating shaft 23 to drive the main board 32 to move.

[0030] Specifically, the reciprocating structure 25 includes a main board 32 and a threading opening 33 provided on the main board 32.

The reciprocating shaft 23 is driven to rotate by the driving motor 24. During the rotation process, the reciprocating shaft 23 drives the main board 32 to move back and forth along the slide groove 35 through the threaded structure on the surface, thereby driving the upper cable 12 to move synchronously, so that the cable can be wound up at different positions of the winding roller 20.

[0031] When in use: When the robot pipeline detection of the present invention is carried out for underground pipeline construction, firstly Figure 1 The robot 1 shown is placed in the manhole, and the cable reel 2 is opened. The robot 1 is placed in the construction position in the manhole. During the construction process, the camera 1 is first placed as shown in FIG. Figure 2Move forward as shown, replace the tire 4 according to the size of the pipe diameter, and adjust the front high beam 6 to raise or lower it according to the diameter of the pipe. Before operation, plug in the aviation plug 4 and push the wire drum roller 1. The motor installed at one end of the wire winding roller 20 can be driven by the lithium battery 18 to drive the wire winding roller 20 to rotate for automatic winding and relaxation. It can also be manually driven by the manual handle 21 to press the wire through the wire pressing wheel 26. After the construction is completed, unplug the aviation plug 13 and put the aviation plug 13 with wire into the special plug on the wire winding drum 2. The robot 1 is disconnected from the cable reel 2 by pressing the inching button 28, or manually reeling the cable during the construction process. If there is any special situation, please press the emergency stop button 29 to stop the cable. After the completion, the air plug 13 returns to the designated position of the air plug, so that the operator can know the status of the cable reel 1 at any time. The pipeline inspection robot is a mechanical, electrical and instrument integration that can automatically walk along the inside of the pipeline, with a variety of sensors and operations or computer automatic control to perform pipeline operations. The system consists of a controller, a crawler, a camera, a cable turntable and a display. The crawler is equipped with a high-definition integrated camera. The pipeline robot is a set of CCTV and camera detection equipment that comprehensively detects the underwater part of the pipeline. The pipeline robot is small and exquisite, and one person can complete the operation, improve work efficiency, and enhance quality. It can be used to detect pipelines with diameters ranging from 300mm to 2000mm; the crawler and the camera adopt a waterproof design with good sealing performance, and the IP68 level can be used for underwater detection (under positive pressure). The battery life of the large-capacity lithium battery is more than 8 hours. During the inspection process, defect images can be quickly captured, and the inspection report can be obtained immediately after the inspection is completed. In addition, the slope curve of the pipeline can be obtained in real time during the inspection process to determine the internal deposition of the pipeline. It is connected to the control system through a cable reel. The high-precision cable reel does not affect the retracting and releasing lines. It can be used for 200-meter-long cables and is suitable for pipe diameters of 300mm--3000mm. The operating screen control system controls the following functions, such as: forward, backward, turning, stopping, speed adjustment of the crawler; lifting, lowering, and lighting adjustment of the lens mount; horizontal or vertical rotation, focusing, zooming, etc. of the lens, front and rear view switching, etc. After verification by a large number of customers, it has been widely used in pipeline inspection, mine inspection, tunnel acceptance, fire rescue, disaster support, high temperature, toxic environment, etc. During the inspection process, the control system can display and record the images sent back by the lens and the status information of the crawler in real time, and can enter notes through the touch screen. We independently developed the model and used a digital camera. The built-in camera resolution reaches 3 million pixels to 5 million pixels. The higher the camera resolution, the stronger the robot's ability to distinguish various defects such as blockage, collapse, dislocation, and cracks inside the pipeline. The 6-wheel drive and imported motor enable the CCTV robot to have the ability to climb a slope of less than 30°, overcome obstacles of 15cm, and carry a load of 80Kg.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
