Description

Technical Field

[0001] This utility model relates to the field of cable insulation coating technology, and in particular to anti-icing coating spraying equipment for 35kV and below uninterrupted power supply operation based on UAV. Background Technology

[0002] Insulation coating robots are important equipment in the power industry. They can perform insulation coating on cables without power interruption. During operation, operators can remotely control them from the ground. They are not limited by complex terrain, are lightweight and convenient, and effectively prevent power accidents caused by exposed wires or aging wire insulation.

[0003] For high-voltage power transmission cables, such as 110kV and above transmission lines, high-viscosity insulating coatings are typically used. High-viscosity coatings adhere better to the cable surface, forming a thicker insulation layer and preventing insulation breakdown. For low-voltage power cables (such as household wiring), lower-viscosity coatings are usually used to ensure insulation performance while maintaining a certain degree of flexibility for easier wiring within buildings. Therefore, there is an urgent need for equipment that can quickly change the coating according to different operating scenarios. Utility Model Content

[0023] Example

[0024] Reference Figures 1-5 This embodiment provides an anti-icing coating spraying device for 35kV and below uninterrupted power operation based on UAV, specifically including a housing 1 and a material rack 2 connected to the housing 1. The material rack 2 is used to place the material cylinder. A spraying mechanism 3 is provided on one side of the housing 1. A pump assembly 4 is provided at the bottom of the housing 1 for conveying the coating in the material cylinder to the spraying mechanism 3. A walking mechanism 5 is provided inside the housing 1. When the device is attached to a cable, the walking mechanism 5 is used to drive the device to move along the cable.

[0025] Pump assembly 4 includes a pump body 401 and a connector 402. The pump body 401 is detachably connected to the housing 1. One connector 402 is connected to the material cylinder, and the other connector 402 is connected to the spraying mechanism 3. The spraying mechanism 3 includes a first electric push rod 301 fixedly connected to the housing 1. A push rod base 302 is fixedly connected to the output end of the first electric push rod 301. A second electric push rod 303 is mounted on the top of the push rod base 302. An L-shaped rod 304 is hinged to the output end of the second electric push rod 303. A nozzle 305 is fixedly connected to one end of the L-shaped rod 304. At least two nozzles 306 are provided on one side of the nozzle 305. There are two spraying mechanisms 3, which are arranged in a mirror symmetrical manner. A rotating shaft 307 is provided on the top of the push rod base 302. The rotating shaft 307 is rotatably connected to the L-shaped rod 304. When the second electric push rod 303 extends or retracts, the L-shaped rod 304 rotates around the rotating shaft 307, causing the two nozzles 305 to move closer or further apart.

[0026] The top of the material rack 2 extends into the housing 1 and is fixedly connected to the housing 1. The bottom of the material rack 2 is horizontal and is used to place the material cylinder. The material rack 2 and the material cylinder are connected by bolts for easy replacement and disassembly. The pump body 401 draws the paint in the material cylinder and supplies it to the two nozzles 305 through the three-way connector. Finally, it is sprayed out by the nozzle 306.

[0027] The first electric push rod 301 is fixedly connected to the part of the material rack 2 located inside the housing 1. A through hole is provided at the bend of the L-shaped rod 304, and the rotating shaft 307 is located inside the through hole.

[0028] Determine the required coating properties (viscosity) based on the work scenario. Simply replace the corresponding barrel and pump assembly 4. It is convenient, quick, and has a wide range of applications.

[0029] The walking mechanism 5 includes at least two walking wheels 501 and fixed plates 502 disposed on both sides of the walking wheels 501. The two walking wheels 501 are driven by a chain, and one of the walking wheels 501 is connected to the output end of a motor 504 through a bevel gear 503. The motor 504 is fixedly connected to the fixed plate 502. A mounting rod 6 is fixedly connected to the top of the housing 1. A camera 7 is provided on the top of the housing 1.

[0030] The fixed plate 502 is fixedly connected to the housing 1. The fixed plate 502 is provided with a bearing. The walking wheel 501 is provided with a walking shaft that works with the bearing. There are two bevel gears 503 that mesh with each other. One of them is fixedly connected to the walking shaft, and the other is fixedly connected to the output end of the motor 504.

[0031] The mounting pole 6 is used to facilitate the drone to mount and transport the equipment, and the camera 7 is used to observe the mounting and transport situation in real time, so that the operator can make adjustments at any time.

[0032] Working principle: First, the equipment is assembled. A drone is used to lift the equipment and transport it directly above the cable. The second electric push rod 303 is operated to open the two nozzles 305. Then, the equipment is slowly lowered so that the cable passes through the area between the two material racks 2 and finally contacts the bottom of the traveling wheel 501. Then, the drone is operated to disconnect from the equipment and the equipment is stably hung on the cable. The first electric push rod 301 and the second electric push rod 303 are operated to position the cable in the middle of the nozzle 306. Then, the motor 504 is started. Through the transmission of the bevel gear 503 and the chain sprocket, the two traveling wheels 501 rotate synchronously. The friction force makes the equipment move along the cable. At the same time, the pump body 401 is started to deliver the paint in the material cylinder to the nozzle 305 and then spray it out through the nozzle 306 to achieve the coating work of the cable.

[0033] Importantly, although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible without substantially departing from the subject matter described in this application, such as changes in the size, structure, shape, and proportion of various elements, as well as variations in temperature, pressure, installation arrangement, material use, color, orientation, etc.; for example, an element shown as integrally formed may be composed of multiple parts or elements, and the position of the elements may be inverted or otherwise altered; therefore, all such modifications should be included within the scope of this invention, and other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments without departing from the scope of this invention.
