Description

Technical Field

[0001] This utility model relates to the field of cable spraying technology, and more specifically, to a high-voltage line insulating paint spraying device. Background Technology

[0002] To address the problem of short circuits in power transmission lines caused by severe weather and to improve the safety and stability of the power grid, the application of insulating varnish to high-voltage lines is of particular importance.

[0003] However, existing high-voltage line insulation varnish spraying technologies have many shortcomings. On the one hand, while liquid extrusion insulation materials are widely used, their problems cannot be ignored: First, this method relies on heavy high-pressure extruders, increasing the difficulty of equipment handling and installation; second, the insulation material is prone to hardening, resulting in slow extrusion speeds and significantly limiting construction efficiency. On the other hand, while direct spraying of insulation varnish improves construction flexibility to some extent, it requires precise control of drones to drag the spray nozzles, demanding extremely high operator skills and making it difficult to ensure uniform spraying, thus leading to significant material waste. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a high-voltage line insulating paint spraying device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] Furthermore, in order to enable the entire device to move on the high-voltage cable, the drive walking mechanism includes a support plate installed inside the protective housing, a drive motor is installed on one side of the support plate, a reducer is installed at the output end of the drive motor, and walking rubber wheels are rotatably installed on both sides of the drive motor.

[0008] Furthermore, in order to provide power for the movement of the traveling rubber wheel on the high-voltage cable, the output end of the reducer rotates through the support plate and is connected to the driving roller, and the central shaft of the traveling rubber wheel rotates through the support plate and is connected to the driven roller. The driving roller and the driven roller are connected by a transmission belt.

[0009] Furthermore, in order to achieve automatic application of insulating varnish to the surface of the sprayed cable, the paint application mechanism includes a positioning frame connected to one side of the protective housing. A limiting open ring is rotatably installed inside the positioning frame. Limiting grooves are opened at both ends of the limiting open ring. Multiple limiting rollers are rotatably installed at both ends of the positioning frame, and the limiting rollers are rotatably installed in the limiting grooves.

[0010] Furthermore, in order to provide power for the rotation of the limiting open ring, gear rings are connected to both sides of the limiting open ring, and transmission rods are rotatably installed on both sides of the positioning frame. Drive gears are connected to both sides of the transmission rods, and the drive gears mesh with the gear rings. One end of the transmission rod rotates through the positioning frame and is connected to a transmission roller.

[0011] Furthermore, in order to ensure that the sprayed insulating varnish is evenly applied to the high-voltage cable by rotating the limiting open ring, a second drive motor is installed inside the positioning frame. The output end of the second drive motor is connected to a second drive roller. A second drive belt is installed between the second drive roller and the first drive roller. Support frames are connected to both sides inside the limiting open ring of the drive motor. An application roller is rotatably installed on one side of the support frame.

[0014] Furthermore, to facilitate the installation of the entire device on the high-voltage cable, a guide plate is connected to one side of the center of the protective housing.

[0015] Furthermore, in order to capture images of the coating of insulating varnish on the high-voltage cables, a high-definition camera is installed on the top side of the protective housing, and a zero-position sensor is installed on the inside side of the protective housing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] According to an embodiment of the present invention, a high-voltage line insulating varnish spraying device is provided.

[0029] like Figures 1-5 As shown, a high-voltage line insulating varnish spraying device according to an embodiment of the present invention includes a metal protective shell 1. The protective shell 1 serves as a carrier for the internal structure of the device, providing support and physical protection. The outer surface of the protective shell 1 is coated with a layer of insulating varnish. A carrier box 2 is connected to the bottom of the protective shell 1. A paint storage tank 3 is installed inside the carrier box 2 to store the insulating varnish. A high-pressure diaphragm pump 4 is installed on the top of the paint storage tank 3. The output end of the high-pressure diaphragm pump 4 is connected to a spraying pipe 5. The high-pressure diaphragm pump 4 can extract the insulating varnish from the paint storage tank 3 and spray it onto the surface of the high-voltage cable through the spraying pipe 5. A storage battery 6 is installed on one side of the high-pressure diaphragm pump 4 to provide power to the various electrical components inside the device. A drive mechanism 7 is provided on one side of the interior of the protective shell 1 to drive the entire device to move automatically on the cable. A paint application mechanism 8 is provided on the other side to evenly apply the sprayed insulating varnish onto the high-voltage line.

[0030] like Figure 5 and Figure 6As shown, the driving walking mechanism 7 includes a support plate 701 installed inside the protective housing 1. A drive motor 702 is installed on one side of the support plate 701. A reducer 703 is installed at the output end of the drive motor 702 to increase the torque output by the drive motor 702. A pair of walking rubber wheels 704 are rotatably installed on both sides of the drive motor 702. By placing the walking rubber wheels 704 on the cable to be sprayed and rolling them, the entire device can be moved on the cable. The output end of the reducer 703 rotates through the support plate 701 and is connected to the main... The driving roller 705 and the two traveling rubber wheels 704 have a central shaft that rotates through the support plate 701 and is connected to the driven roller 706. The driving roller 705 and the driven roller 706 are connected by a transmission belt 707. The driving roller 705 is driven to rotate by a transmission motor 702 and a reducer 703, which in turn drives the two driven rollers 706 to rotate via the transmission belt 707. This causes the traveling rubber wheel 704 at one end of the driven roller 706 to move on the high-voltage cable, thus realizing the automated movement of the entire device on the high-voltage line during the spraying of insulating varnish.

[0031] like Figures 2-7 As shown, the paint application mechanism 8 includes a positioning frame 801 connected to one side of the protective housing 1. A limiting open ring 802 is rotatably installed inside the positioning frame 801. Limiting grooves 803 are formed at both ends of the limiting open ring 802. Multiple limiting rollers 804 are rotatably installed at both ends of the positioning frame 801, and are rotatably installed within the limiting grooves 803, providing rotational support for the limiting open ring 802. A pair of gear rings 805 are connected to both sides of the limiting open ring 802. A pair of transmission rods 806 are rotatably installed on both sides of the positioning frame 801. Each transmission rod 806 has a drive gear 807 connected to both sides, meshing with the gear rings 805. One end of the transmission rod 806 rotatably passes through the positioning frame 801 and is connected to a transmission roller 808. The positioning frame 801 contains... A second drive motor 812 is connected to a second drive roller 813 at its output end. A second drive belt 809 is installed between the second drive roller 813 and the first drive roller 808. Support frames 810 are connected to both sides of the inner side of the limiting open ring 802. An applicator roller 811 is rotatably mounted on one side of the support frame 810. A sponge sleeve is installed on the surface of the applicator roller 811. The second drive motor 812 drives the second drive roller 813 to rotate, which in turn drives the first drive roller 808 and the drive rod 806 to rotate. In turn, the drive rod 806 drives the gear ring 805 and the limiting open ring 802 to rotate through the drive gear 807 on its surface. After the limiting open ring 802 rotates, the applicator roller 811 on the support frames 810 on both sides inside it can rotate around the high-voltage cable to evenly apply the insulating varnish sprayed on the high-voltage cable.

[0032] like Figures 1-6As shown, a control box 9 is connected to one side of the support plate 701. A microcontroller 10 is installed inside the control box 9 for automated control of various electrical components within the device. A wireless communication module 11 is installed on one side of the microcontroller 10. This wireless communication module 11 is a 4G / 5G communication module, capable of wireless transmission of control signals. A lifting block 12 is connected to the top of the protective shell 1. An electric telescopic rod 13 is installed on one side of the lifting block 12. A limit hole 14 is opened on the surface of the lifting block 12. The end of the electric telescopic rod 13 cooperates with the limit hole 14. When the entire device needs to be lifted and transported to the high-voltage cable by a drone, the drone's hook is placed inside the lifting block 12, and then the end of the electric telescopic rod 13 is extended to install the limit hole 14. Within the limiting hole 14, the hook is used to limit the movement of the drone. A guide plate 15 is connected to one side of the middle of the surface of the protective shell 1. When the entire device is hoisted by the drone, the high-voltage cable can enter the entire device along the guide plate 15 and contact the walking rubber wheel 704 inside the protective shell 1. A high-definition camera 16 is installed on the top side of the protective shell 1. It is used to take pictures of the cable after it has been coated with insulating varnish and transmit the images wirelessly through the wireless communication module 11, so as to facilitate real-time observation of the coating on the cable surface. A zero-position sensor 17 is installed on one side of the inside of the protective shell 1. When the entire device is removed from the high-voltage cable, the limiting opening ring 802 can rotate to the initial point, so that the drone can hoist and remove the entire device through the opening.

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] In practical use, the entire device is hoisted onto the high-voltage cable using a drone, causing the two traveling rubber wheels 704 inside the protective housing 1 to roll into contact with the high-voltage cable. The high-voltage diaphragm pump 4 is started via the wireless communication module 11, drawing insulating varnish from the paint storage tank 3 and spraying it onto the surface of the high-voltage cable through the spraying pipe 5. The drive motors 702 and 812 are then started, driving the active roller 705 to rotate via the drive motor 702 and reducer 703. This active roller 705, through the drive belt 707, drives the two driven rollers 706 to rotate, thus causing the driven rollers... The traveling rubber wheel 704 at one end of 706 moves on the high-voltage cable, realizing the automated movement and spraying of the entire device on the high-voltage cable during the spraying of insulating varnish. While moving and spraying, the transmission motor 812 drives the transmission roller 813 to rotate, which in turn drives the transmission roller 808 and the transmission rod 806 to rotate. This causes the transmission rod 806 to drive the gear ring 805 and the limiting open ring 802 to rotate through the surface drive gear 807. After the limiting open ring 802 rotates, the coating rollers 811 on the internal two side support frames 810 can rotate around the high-voltage cable to evenly coat the insulating varnish sprayed on the high-voltage cable.
