DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-7 The present invention provides a technical solution: a device for repairing the inner lining of an urban underground pipeline, comprising: a winding device 2, a large light chain 1, a small light chain 4 and a control console 3, wherein the end of the large light chain 1 is connected to the winding device 2 by a wire, and the small light chains 4 are provided with eight and connected end to end, and the small light chains 4 at the end are connected to the winding device 2 by a wire, and the control console 3 is installed on one side of the winding device 2;

[0023] The headlight chain 1 includes a symmetrically arranged telescopic plate 7 and a lifting rod 12, the lifting rod 12 is rotatably connected to the telescopic plate 7 and the end of the lifting rod 12 is connected to a roller 5, a camera 6 is installed on the surface of the telescopic plate 7 at the front end of the headlight chain 1, a motor housing 10 is installed on the surface of the telescopic plate 7 at the rear end of the headlight chain 1, a motor is installed inside the motor housing 10, an aviation plug 9 is arranged at the end of the motor housing 10, an angle adjustment screw 11 is connected to the power output end of the motor, and the end of the angle adjustment screw 11 is connected to the telescopic plate 7 at the front end of the headlight chain 1, and the construction range of the headlight chain 1 is 150mm-600mm;

[0024] The small light chain 4 includes a pressure wheel mounting plate 33, a light chain connecting pipe 34, a connecting pipe seat 35, a universal joint 37, a universal joint joint 38, a light tube 39 and a navigation socket 40. A pull ring 43 is installed at the end of the small light chain 4, a draw hook 30 is installed at the front end of the small light chain 4, a fixing block 32 is installed at the front end of the small light chain 4 arranged at the front end, and a camera 6 is installed at the front end of the fixing block 32. The construction range of the small light chain 4 is 150mm-600mm;

[0025] The control console 3 includes a control box 24, a display screen 28, a wireless receiver 27 and control buttons. The control buttons and the display screen 28 are respectively installed on the surface of the control box 24. The wireless receiver 27 is vertically installed on the top of the control box 24. The control buttons include three, namely a start button 25, a jog button 26 and an emergency stop button 29. The control console 3 is connected to the winding device 2 and can control the construction status. It is equipped with a 19-inch display screen and wireless network communication equipment.

[0026] Further improvement, such as Figure 2 As shown: the universal joint 38 and the universal joint 37 are installed at the front end of the small light chain 4, and the universal joint 37 of the rear small light chain 4 is connected to the pull ring 43 of the front small light chain 4, and a temperature sensor 41 is installed at the tail of the small light chain 4 at the end.

[0027] Further improvement, such as Figure 2 As shown: the light chain connecting tube 34 and the light tube 39 are connected between the pressure wheel mounting plate 33 and the connecting tube seat 35. There are three light chain connecting tubes 34 in total and they are distributed in a ring shape with the light tube 39 as the center. Small light chain pressure wheels 36 are respectively installed on the pressure wheel mounting plate 33 and the connecting tube seat 35.

[0028] The ultraviolet lamps on the light chain trigger the light-sensitive factors in the ultraviolet lining material, so that the resin in the lining material reacts to form a solid tube lining, effectively blocking and repairing damaged pipes, forming a solid "tube in a tube". Two 2-megapixel cameras are installed at the front and rear ends of the light chain, equipped with low-beam and high-beam LED bulbs, to clearly see various adverse conditions inside the pipeline. Each section of the light chain is divided into three wheels with equal circumferences so that the light chain can slide smoothly into the pipeline. Flexible connection methods are adopted between each section so that the light chain can achieve a relatively large curvature. Each section of the light chain uses several sensors to collect the temperature in the pipeline. 600mm-2000mm can be telescopic according to the size of the pipe diameter through embedded screws and connections and connecting legs to meet the different requirements of pipe diameters.

[0029] Further improvement, such as Figure 2As shown: the winding device 2 includes a bracket 19, a winding drum 18, a rocker cross bar 15, a manual rocker arm 22, a driving sprocket 23 and a motor reducer 20.

A motor connected to the motor reducer 20 is also installed on the bracket 19. The motor reducer 20 is connected to the driving sprocket 23 using a sprocket chain 13, and the motor reducer 20 is also connected to the manual rocker arm 22 through a sprocket chain 13.

[0030] The winding device 2 realizes the integrated function of mechanical winding and manual winding and releasing. It is provided with a rotating shaft with an axis inside, a rotating drum sleeved on the outside of the rotating shaft, and a manual rocker 22 at the end of the rotating shaft, which is connected to the aerial plug through a slip ring; the cable is fixed by a back and forth screw rod to bend the wire parallel to the winding drum 18, and there is a wire release counting sensor at the output end, which is transmitted to the control desktop through the sensor to know the length of the current output line. In this embodiment, after the transmission line is pulled out, the sprocket and the motor can be used to limit the position and use the winding drum 18 to wind the line, which improves the shortcomings of the prior art that buttons need to be set and motors need to be installed. The winding device 2 also includes a wire drum bracket 19 placed outside the winding drum 18, which can be installed on a construction vehicle. This embodiment is set to prevent the cable from wear and tear and extend the service life. The wire is rolled into the wire drum through the wire drum bracket 19 to make the construction site clean and convenient. The transmission line is connected to the aerial plug and wound around the rotating drum. The automatic cable reel comprises a frame and a cable drum rotatably mounted on the frame, a driving mechanism for rotating the cable drum, and a clutch mechanism arranged in the inner cavity of the axial bracket. The communication and power-on performances are enhanced by arranging a rotating shaft, a rotating drum and a wiring plug, thereby ensuring the functional basis of transmitting electric energy and winding the cable reel. The sprocket at the end of the rotating drum is used in a reduction ratio with the output of the motor, thereby overcoming the shortcomings of the electric cable reel in the prior art in terms of power consumption and high cost, and achieving the technical effects of free cable extension and retraction, simple structure and energy saving.

[0032] Further improvement, such as Figure 2 As shown: a damper 17 is also installed on the side wall of the bracket 19, and a clutch handle 21 is also installed at the bottom of the front end of the bracket 19.

[0033] Specifically, the console 3 is also provided with input and output channels, a network interface, an audio and video interface, an alarm input and output interface, and a TF card storage interface. Images and sounds are transmitted in real time through wired and wireless networks. A digital processor with faster computing speed is used, which can quickly compress larger and clearer images. An advanced operating system and audio and video compression algorithms are used to make image transmission smoother, clearer and more delicate.

[0034] 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.
