AI Technical Summary
[0003]现有技术中传统喷涂设备依赖人工操作或固定轨迹,人工操作时易因手臂抖动导致喷涂偏差,出现局部漏喷;固定喷涂机对不规则设备的凹陷部位无法精准覆盖,涂层厚度偏差较大,影响绝缘性能
[0016]This invention utilizes a micro-motor in the adjustment assembly. The output of the micro-motor drives a fixedly connected threaded rod to rotate. The threaded rod, through its own threaded structure, forms a threaded transmission with the inner wall of the adjustment block. The bottom of the adjustment block is fixedly connected to the spray guide tube, and the left side of the spray guide tube is slidably connected to a guide groove opened in the inner wall of the guide tube via a limiting slider. The guide groove provides linear movement guidance for the limiting slider, preventing the spray guide tube from deflecting when the threaded rod rotates. Therefore, when the threaded rod rotates, the adjustment block will move linearly along the axis of the threaded rod, simultaneously driving the spray guide tube to slide along the guide groove via the limiting slider, realizing the extension and retraction adjustment of the spray guide tube inside the guide tube. This allows the paint to be directly atomized and sprayed out through the first atomizing nozzle on the surface of the guide tube, covering the corresponding area of the equipment to be sprayed; another part of the paint enters the interior of the spray guide tube and is atomized and sprayed out through the second atomizing nozzle on the surface of the spray guide tube and the third atomizing nozzle at the end away from the limiting slider. The extension and retraction length of the spray guide tube is adjusted by a micro-motor: when the spray guide tube extends outward, the spraying range of atomizing nozzles two and three expands away from the guide tube, covering larger electrical equipment; when the spray guide tube retracts inward, atomizing nozzles two and three approach the guide tube, suitable for precise spraying of small equipment such as small terminals. Simultaneously, atomizing nozzles one, two, and three all employ a high-pressure atomization design, atomizing the insulating coating into uniform microparticles, ensuring a continuous and dense insulating coating on the surface of the electrical equipment, improving insulation protection, and enabling multi-angle spraying. Coating thickness deviation is controlled; even for irregularly shaped parts, adjusting the extension and retraction length of the spray guide tube allows the nozzles to be close to the surface to be sprayed, avoiding missed areas and ensuring the integrity and uniformity of the insulating coating.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying device technology, and in particular to a high-voltage insulation spraying device for power protection. Background Technology
[0002] High-voltage insulation spraying equipment is mainly used in power systems, especially for the insulation protection of high-voltage power equipment. With the continuous development of the power industry and the advancement of power grid construction, high-voltage equipment faces higher insulation requirements in daily use. High-voltage power equipment, especially in high-voltage transmission lines and substation equipment, is exposed to harsh environmental conditions for extended periods, such as high humidity, strong ultraviolet radiation, and pollutants. These factors can lead to aging, cracking, and even breakdown of insulation materials. Therefore, effective additional protection is needed for these devices to extend their service life and ensure the safe operation of the power system. To improve the safety, reliability, and service life of equipment, high-voltage insulation spraying technology has become an effective solution.
[0003] In existing technologies, traditional spraying equipment relies on manual operation or fixed trajectories. When operating manually, arm tremors can easily cause spraying deviations and result in localized missed spraying. Fixed spraying machines cannot accurately cover the recessed areas of irregular equipment, resulting in large deviations in coating thickness and affecting insulation performance. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a high-voltage insulation spraying device for power protection.
[0005] This utility model is achieved by the following technical solution: a high-voltage insulating spraying device for power protection, including a guide pipe, an adjusting component is provided inside the guide pipe, and a connecting component is provided at the bottom of the guide pipe.
[0006] The adjustment assembly includes a guide groove formed on the inner wall of the guide tube. A limit slider is slidably connected to the inner wall of the guide groove. A spray guide tube is fixedly connected to the right side of the limit slider. An atomizing nozzle is provided on the surface of the guide tube. An atomizing nozzle is provided on the surface of the spray guide tube. An atomizing nozzle is provided at the end of the spray guide tube away from the limit slider. An adjustment block is fixedly connected to the top of the spray guide tube. A threaded rod is threadedly connected to the inner wall of the adjustment block. A micro motor is fixedly connected to the end of the threaded rod away from the adjustment block.
[0007] As a further improvement to the above solution, the outer wall of the spray guide tube is slidably connected to the inner wall of the guide tube, the bottom of the micro motor is fixedly connected to the top of the guide tube, and several guide grooves are provided.
[0008] The above technical solution activates the micro motor in the adjustment assembly. The output of the micro motor drives the fixedly connected threaded rod to rotate. The threaded rod forms a threaded transmission with the inner wall of the adjustment block through its own threaded structure. The bottom of the adjustment block is fixedly connected to the spray guide tube, and the left side of the spray guide tube is slidably connected to the guide groove opened in the inner wall of the guide tube through a limiting slider. The guide groove provides linear movement guidance for the limiting slider, preventing the spray guide tube from deflecting when it rotates with the threaded rod.
[0009] As a further improvement to the above solution, the connecting component includes a connecting seat, the outer wall of which is slidably connected to the surface of the guide tube, and a limiting groove is formed at the bottom of the connecting seat.
[0010] As a further improvement to the above solution, a connecting slider is slidably connected to the inner wall of the limiting groove, the connecting slider penetrates the inner wall of the limiting groove and extends therethrough, and a high-pressure air pipe is threadedly connected to the outer wall of the connecting slider.
[0011] As a further improvement to the above solution, a sealing groove is provided at the top of the high-pressure air pipe, a positioning hole is provided at the bottom of the inner wall of the sealing groove, a sealing ring is provided in contact with the inner wall of the positioning hole, and the outer wall of the sealing ring is provided in contact with the inner wall of the sealing groove.
[0012] As a further improvement to the above scheme, an air inlet is provided at the end of the high-pressure air pipe away from the guide pipe, and a feed inlet is provided on the surface of the high-pressure air pipe.
[0013] As a further improvement to the above solution, a positioning groove is provided on the surface of the guide pipe, a positioning block is slidably connected to the inner wall of the positioning groove, and the outer wall of the positioning block is fixedly connected to the inner wall of the connecting seat.
[0014] Through the above technical solution, the outer wall of the connector of the connecting component is slidably connected to the surface of the guide tube. During the sliding process, the positioning block fixed on the inner wall of the connector slides along the inner wall of the positioning groove opened on the surface of the guide tube. The cooperation between the positioning groove and the positioning block restricts the circumferential rotation of the connector when it moves along the axis of the guide tube, ensuring that the connector always maintains coaxial positioning with the guide tube, and avoiding the risk of leakage caused by interface misalignment during subsequent docking.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention utilizes a micro-motor in the adjustment assembly. The output of the micro-motor drives a fixedly connected threaded rod to rotate. The threaded rod, through its own threaded structure, forms a threaded transmission with the inner wall of the adjustment block. The bottom of the adjustment block is fixedly connected to the spray guide tube, and the left side of the spray guide tube is slidably connected to a guide groove opened in the inner wall of the guide tube via a limiting slider. The guide groove provides linear movement guidance for the limiting slider, preventing the spray guide tube from deflecting when the threaded rod rotates. Therefore, when the threaded rod rotates, the adjustment block will move linearly along the axis of the threaded rod, simultaneously driving the spray guide tube to slide along the guide groove via the limiting slider, realizing the extension and retraction adjustment of the spray guide tube inside the guide tube. This allows the paint to be directly atomized and sprayed out through the first atomizing nozzle on the surface of the guide tube, covering the corresponding area of the equipment to be sprayed; another part of the paint enters the interior of the spray guide tube and is atomized and sprayed out through the second atomizing nozzle on the surface of the spray guide tube and the third atomizing nozzle at the end away from the limiting slider. The extension and retraction length of the spray guide tube is adjusted by a micro-motor: when the spray guide tube extends outward, the spraying range of atomizing nozzles two and three expands away from the guide tube, covering larger electrical equipment; when the spray guide tube retracts inward, atomizing nozzles two and three approach the guide tube, suitable for precise spraying of small equipment such as small terminals.

Coating thickness deviation is controlled; even for irregularly shaped parts, adjusting the extension and retraction length of the spray guide tube allows the nozzles to be close to the surface to be sprayed, avoiding missed areas and ensuring the integrity and uniformity of the insulating coating.
[0017] This invention features a connecting component whose outer wall is slidably connected to the surface of a guide tube. During sliding, a positioning block fixed to the inner wall of the connecting component slides along the inner wall of a positioning groove on the surface of the guide tube. The cooperation between the positioning groove and the positioning block restricts circumferential rotation of the connecting component when it moves along the axis of the guide tube, ensuring that the connecting component remains coaxially positioned with the guide tube and avoiding the risk of leakage due to interface misalignment during subsequent docking. A connecting slider is slidably connected to the inner wall of a limiting groove at the bottom of the connecting component. The connecting slider passes through the limiting groove and extends to the outside, with its outer wall threadedly connected to a high-pressure air pipe. By rotating the high-pressure air pipe, quick assembly and disassembly of the connecting slider can be achieved, facilitating the replacement or maintenance of the high-pressure air pipe. The sliding connector aligns with the high-pressure air pipe, enhancing the device's adaptability to external equipment. A positioning hole is located at the bottom of the sealing groove at the top of the high-pressure air pipe. The inner wall of the positioning hole contacts the sealing ring, and the outer wall of the sealing ring fits against the inner wall of the sealing groove. After the high-pressure air pipe and connector are aligned, the sealing ring undergoes elastic deformation under the pressure of the sealing groove and connector. This fills the threaded gap between the high-pressure air pipe and the connector, and also achieves radial positioning of the sealing ring through the positioning hole, preventing displacement caused by high-pressure gas or coating impact. This effectively blocks the leakage path of high-pressure gas and insulating coating, ensuring pressure stability and operational safety during spraying. An air inlet at the end of the high-pressure air pipe away from the guide pipe connects to an external high-pressure gas source, such as an air compressor, to supply high-pressure gas into the device. A feed inlet on its surface connects to external coating supply equipment, such as a coating tank, allowing insulating coating to enter the high-pressure air pipe. High-pressure gas is transported through the high-pressure air pipe to the connector, and then enters the connecting channel between the connector and the guide pipe. The design features double sealing and quick assembly / disassembly, solving the problems of poor compatibility, easy leakage, difficult maintenance, and short lifespan of traditional connection structures. It provides a stable, safe, and flexible material and power transmission channel for high-voltage insulation spraying devices. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Example:
[0028] Please combine Figure 1-6 The high-voltage insulation spraying device for power protection in this embodiment includes a guide pipe 1, an adjustment component 2 is provided inside the guide pipe 1, and a connecting component 3 is provided at the bottom of the guide pipe 1.
[0029] The adjustment component 2 includes a guide groove 201, which is formed on the inner wall of the guide tube 1. A limit slider 202 is slidably connected to the inner wall of the guide groove 201. A spray guide tube 203 is fixedly connected to the right side of the limit slider 202. An atomizing nozzle 1 204 is provided on the surface of the guide tube 1. An atomizing nozzle 205 is provided on the surface of the spray guide tube 203. An atomizing nozzle 3 206 is provided at the end of the spray guide tube 203 away from the limit slider 202. An adjustment block 207 is fixedly connected to the top of the spray guide tube 203. A threaded rod 208 is threadedly connected to the inner wall of the adjustment block 207. A micro motor 209 is fixedly connected to the end of the threaded rod 208 away from the adjustment block 207.
[0030] The outer wall of the spray guide tube 203 is slidably connected to the inner wall of the guide tube 1, the bottom of the micro motor 209 is fixedly connected to the top of the guide tube 1, and several guide grooves 201 are provided.
[0031] The connecting component 3 includes a connecting seat 301, the outer wall of which is slidably connected to the surface of the guide tube 1, and a limiting groove 302 is formed at the bottom of the connecting seat 301.
[0032] A connecting slider 303 is slidably connected to the inner wall of the limiting slide groove 302. The connecting slider 303 passes through the inner wall of the limiting slide groove 302 and extends thereto. A high-pressure air pipe 304 is threadedly connected to the outer wall of the connecting slider 303.
[0033] A sealing groove 305 is provided at the top of the high-pressure air pipe 304, and a positioning hole 306 is provided at the bottom of the inner wall of the sealing groove 305. A sealing ring 307 is provided in contact with the inner wall of the positioning hole 306, and the outer wall of the sealing ring 307 is provided in contact with the inner wall of the sealing groove 305.
[0034] An air inlet 308 is provided at the end of the high-pressure air pipe 304 away from the guide pipe 1, and a feed inlet 309 is provided on the surface of the high-pressure air pipe 304.
[0035] The surface of the guide tube 1 is provided with a positioning groove 310, and a positioning block 311 is slidably connected to the inner wall of the positioning groove 310. The outer wall of the positioning block 311 is fixedly connected to the inner wall of the connecting seat 301.
[0036] The implementation principle of the high-voltage insulation spraying device for power protection in this embodiment is as follows: By activating the micro motor 209 in the adjustment component 2, the output end of the micro motor 209 drives the fixedly connected threaded rod 208 to rotate. The threaded rod 208 forms a threaded transmission with the inner wall of the adjustment block 207 through its own thread structure. The bottom of the adjustment block 207 is fixedly connected to the spraying guide tube 203, and the left side of the spraying guide tube 203 is slidably connected to the guide groove 201 opened in the inner wall of the guide tube 1 through the limiting slider 202. The guide groove 201 provides linear movement guidance for the limiting slider 202, preventing the spraying guide tube 203 from deflecting when it rotates with the threaded rod 208. Therefore, when the threaded rod 208 rotates, the adjustment block 207 will move linearly along the axis of the threaded rod 208, synchronously driving the spraying guide tube 203 to slide along the guide groove 201 through the limiting slider 202, realizing the extension and retraction adjustment of the spraying guide tube 203 inside the guide tube 1. The coating material can be directly atomized and sprayed out through the atomizing nozzle 204 on the surface of the guide tube 1, covering the equipment to be coated in the corresponding area of the guide tube 1; another part of the coating material enters the interior of the spray guide tube 203 and is atomized and sprayed out through the atomizing nozzle 205 on the surface of the spray guide tube 203 and the atomizing nozzle 206 at the end away from the limiting slider 202. The extension and retraction length of the spray guide tube 1 is adjusted by the micro motor 209: when the spray guide tube 203 extends outward, the spraying range of the atomizing nozzles 205 and 206 expands away from the guide tube 1, which can cover larger electrical equipment; when the spray guide tube 203 retracts inward, the atomizing nozzles 205 and 206 move closer to the guide tube 1, which is suitable for precise spraying of small equipment such as small terminals. Meanwhile, atomizing nozzles 204, 205, and 206 all employ a high-pressure atomization design, atomizing the insulating coating into uniform microparticles. This ensures a continuous and dense insulating coating on the surface of the power equipment, enhancing insulation protection and enabling multi-angle spraying. Coating thickness deviation is controlled; even for irregularly shaped parts, adjusting the extension length of the spray guide tube 203 allows the nozzle to be close to the surface to be sprayed, preventing missed areas and ensuring the integrity and uniformity of the insulating coating. The outer wall of the connecting seat 301 of the connecting assembly 3 is slidably connected to the surface of the guide tube 1. During sliding, the positioning block 311 fixed to the inner wall of the connecting seat 301 slides along the inner wall of the positioning groove 310 on the surface of the guide tube 1. The cooperation between the positioning groove 310 and the positioning block 311 restricts the circumferential rotation of the connecting seat 301 when it moves along the axial direction of the guide tube 1, ensuring that the connecting seat 301 remains coaxially positioned with the guide tube 1, avoiding the risk of leakage due to interface misalignment during subsequent docking.A connecting slider 303 is slidably connected to the inner wall of the limiting groove 302 at the bottom of the connecting seat 301. The connecting slider 303 passes through the limiting groove 302 and extends to the outside. Its outer wall is threadedly connected to the high-pressure air pipe 304. By rotating the high-pressure air pipe 304, quick assembly and disassembly with the connecting slider 303 can be achieved, facilitating the replacement or maintenance of the high-pressure air pipe 304. This allows the sliding connecting slider 303 to align with the high-pressure air pipe 304, improving the adaptability of the device to external equipment. A positioning hole 306 is provided at the bottom of the inner wall of the sealing groove 305 at the top of the high-pressure air pipe 304. The inner wall of the positioning hole 306 contacts the sealing ring 307, and the outer wall of the sealing ring 307 fits against the inner wall of the sealing groove 305. After the high-pressure air pipe 304 and the connecting slider 303 are aligned, the sealing ring 307 undergoes elastic deformation under the compression of the sealing groove 305 and the connecting slider 303. This deformation fills the thread gap between the high-pressure air pipe 304 and the connecting slider 303, and... The sealing ring 307 is radially positioned via the positioning hole 306, preventing displacement of the sealing ring 307 due to impact from high-pressure gas or coating. This effectively blocks the leakage path of high-pressure gas and insulating coating, ensuring pressure stability and operational safety during spraying. The air inlet 308 at the end of the high-pressure gas pipe 304 away from the guide pipe 1 is used to connect to an external high-pressure gas source, such as an air compressor, to deliver high-pressure gas into the device. The feed inlet 309 on its surface connects to external coating supply equipment, such as a coating storage tank, through which the insulating coating enters the high-pressure gas pipe 304. High-pressure gas is transported through the high-pressure gas pipe 304 to the connecting slider 303, and then enters the connecting channel between the connecting seat 301 and the guide pipe 1. Through a double-sealed, quick-disassembly design, the problems of poor compatibility, easy leakage, difficult maintenance, and short lifespan of traditional connection structures are solved, providing a stable, safe, and flexible material and power transmission channel for the high-pressure insulating spraying device.
