Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-washing drone technology, specifically a landing buffer device for water-washing drones. Background Technology
[0002] Transmission lines operate outdoors for extended periods, and the numerous ordinary suspension insulators, anti-pollution insulators, and tempered glass insulators used on these lines accumulate contaminants due to electromagnetic fields, rainwater erosion, and wind. These contaminants adhere to the insulator surface, and in foggy or drizzly weather, the contaminants become damp, forming continuous conductive paths and reducing the creepage distance of the insulators. Several flashover accidents due to pollution have occurred within the system. To ensure that the lines do not experience reduced insulation performance and trigger pollution-induced tripping due to these contaminants, it is essential to clean the line insulators according to the actual site conditions.
[0003] Previously, cleaning was carried out by tying ordinary towels to the end of the insulated operating rod, which was not only inefficient but also ineffective. By using a more technologically advanced unmanned aerial vehicle (UAV) equipped with a water gun and a pure water tank, and keeping the operator away from live parts, the cleaning method can not only improve the safety of the operation but also greatly improve the efficiency of the operation.
[0004] The water tank filled with pure water fixed to the drone increases the weight of the entire drone. Therefore, when the drone lands, it will be subject to a certain impact force when it comes into contact with the ground, which may cause internal parts to loosen or even be damaged, thereby reducing the service life of the drone. In addition, when the water tank moves with the drone, the pure water in the tank will slosh around, making it difficult to ensure the stability of the drone during flight. Utility Model Content
[0005] To address the aforementioned issues, this invention proposes a landing buffer device for water-washing drones. It first absorbs some of the impact force during drone landing using a shock-absorbing pad, and then absorbs the overall impact force of the device during landing using a second buffer component located in the first and second grooves. The second buffer component in the first groove can also absorb some of the impact force of the drone on the landing support during landing, thereby mitigating the impact force during drone landing and extending its service life. Simultaneously, multiple first buffer components are provided at the top and bottom of the water tank to reduce the impact of pure water sloshing in the tank on the drone's stability during movement.
[0006] The technical solution adopted is as follows:
[0007] A landing buffer device for a water-washing drone includes a water-washing device, a drone, a landing support, and a buffer assembly, wherein the buffer assembly includes a first buffer and a second buffer.
[0008] The drone is equipped with a water rinsing device mounting platform at its bottom, and the water rinsing device is fixed on the mounting platform.
[0009] The water rinsing device includes a water gun and a water tank. The water tank is connected to the water gun. The water gun is set above the water tank and fixedly connected to the drone. The bottom and top of the water tank are fixed to the installation platform by multiple first buffers. Second buffers are fixed around the installation platform and connected to the landing support.
[0010] In a further preferred embodiment of the present invention, the installation platform includes fixed rods arranged around the bottom of the drone and a base plate fixedly connected to the four fixed rods. One fixed rod is fixedly connected to a first buffer component, and the base plate is fixedly connected to multiple first buffer components respectively; used to fix the water rinsing device.
[0011] A further preferred embodiment of the present invention includes a first upper plate, a first lower plate, and multiple dampers. The multiple dampers are symmetrically arranged between the first upper plate and the first lower plate and are fixedly connected to the first upper plate and the first lower plate respectively. Each damper is fitted with a first spring, which is fixedly connected to the first upper plate and the first lower plate respectively. This is used to reduce the impact of pure water sloshing in the water tank on the stability of the drone.
[0012] A further preferred embodiment of the present invention is that the fixing rods around the base plate each have a first groove with an opening facing outwards, and the second buffer is disposed in the first groove; this is used to reduce the impact force of the drone on the landing support when the drone lands.
[0013] A further preferred embodiment of the present invention includes a second upper plate, a second lower plate, a second upper spring, a second lower spring, and a sliding rod. The two ends of the sliding rod are fixedly connected to the second upper plate and the second lower plate, respectively. The landing bracket, the second upper spring, and the second lower spring are respectively sleeved on the sliding rod. The second upper spring is positioned above the second lower spring, and the landing bracket is positioned between the second upper spring and the second lower spring, respectively abutting against the second upper spring and the second lower spring; used to absorb the impact force when the UAV lands.
[0014] A further optimization of the technical solution of this utility model is that shock-absorbing landing feet are provided at the bottom of the four sides of the landing bracket, and the landing bracket is connected to the shock-absorbing landing feet through a second buffer; this is used to reduce the impact force of the whole device on the shock-absorbing landing feet when the UAV lands.
[0015] A further preferred embodiment of the present invention is that the shock-absorbing landing foot includes a landing foot and a fixing block. The fixing block is fixed to the top of the landing foot, and a second groove is provided on the inner side of the fixing block. A second buffer is fixed in the second groove. This is used to fix the second buffer, so that the landing bracket can move on the fixing block, thereby reducing the impact force.
[0016] A further optimization of the technical solution of this utility model is that a shock-absorbing pad is provided at the bottom of the landing foot to absorb part of the impact force when the drone lands.
[0017] Compared with the prior art, the advantages of this utility model are:
[0018] 1. This utility model first absorbs part of the impact force when the drone lands through the shock-absorbing pad, and then absorbs the impact force of the whole device when the drone lands through the second buffer set in the first groove and the second groove. The second buffer in the first groove can also absorb part of the impact force of the drone on the landing support when the drone lands, thereby reducing the impact force when the drone lands and extending its service life.
[0019] 2. This utility model reduces the impact of pure water sloshing in the water tank on the stability of the drone during its movement by providing multiple first buffers at the top and bottom of the water tank. Attached Figure Description

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Example
[0025] like Figure 1-3 As shown, this embodiment of a water-washing drone landing buffer device includes a water-washing device, a drone 1, a landing support 7, a buffer assembly, and a shock-absorbing landing foot 8; the buffer assembly includes a first buffer 5 and a second buffer 66, and the water-washing device includes a water gun 3 and a water tank 4, with the water gun 3 connected to the water tank 4.
[0026] In this embodiment, an installation platform 2 is fixed around the bottom of the drone 1. The installation platform 2 includes a fixing rod 21 and a base plate 22 arranged around the bottom of the drone 1. One end of the fixing rod 21 is fixedly connected to the drone 1, and the other end is fixedly connected to the base plate 22.
[0027] In this embodiment, a partition 9 is provided above the water tank 4. The partition 9 is fixedly connected to four fixed rods 21. Multiple first buffers 5 are provided at the bottom of the partition 9 and the top of the base plate 22. The first buffer 5 at the bottom of the partition 9 is fixedly connected to the top of the water tank 4, and the first buffer 5 at the top of the base plate 22 is fixedly connected to the bottom of the water tank 4. When the pure water in the water tank 4 tilts along with the movement direction of the drone 1, the stability of the water tank 4 is ensured as much as possible, thereby reducing the impact of the pure water in the water tank 4 shaking on the drone 1. At the same time, since the water gun 3 is continuously outputting water, the weight of the water tank 4 is constantly changing. The multiple first buffers 5 at the bottom of the partition 9 and the top of the base plate 22 can reduce the impact of the reduction of water volume in the water tank 4 on the drone 1.
[0028] like Figure 2 As shown, in this embodiment, the first buffer 5 includes a first upper plate, a first lower plate 52, and four dampers 53. The four dampers 53 are symmetrically arranged in pairs between the first upper plate and the first lower plate 52 and are fixedly connected to the first upper plate and the first lower plate 52 respectively. Each damper 53 is fitted with a first spring 54, which is fixedly connected to the first upper plate and the first lower plate 52 respectively.
[0029] The first upper plate of the first buffer member 5, which is located at the bottom of the partition 9, is fixedly connected to the bottom of the partition 9, and the first lower plate 52 is fixedly connected to the water tank 4. The first upper plate of the first buffer member 5, which is located at the top of the base plate 22, is fixedly connected to the water tank 4, and the first lower plate 52 is fixedly connected to the base plate 22.
[0030] In this embodiment, the water gun 3 is disposed between the partition 9 and the drone 1. The top of the water gun 3 is fixedly connected to the drone 1, and the bottom is fixedly connected to the partition 9.
[0031] In this embodiment, the fixing rods 21 arranged around the base plate 22 each have a first groove with an opening facing outward, and the second buffer 66 is arranged in the first groove.
[0032] like Figure 3As shown, the second buffer 66 includes a second upper plate 61, a second lower plate 62, a second upper spring 64, a second lower spring 65, and a slide rod 63. The two ends of the slide rod 63 are fixedly connected to the second upper plate 61 and the second lower plate 62, respectively. The landing bracket 7, the second upper spring 64, and the second lower spring 65 are respectively sleeved on the slide rod 63. The second upper spring 64 is located above the second lower spring 65. The landing bracket 7 is located between the first upper spring and the second lower spring 65 and abuts against the second upper spring 64 and the second lower spring 65, respectively.
[0033] The second upper plate 61 of the second buffer member 66, which is located in the first groove, is fixedly connected to the upper groove surface of the first groove. The second lower plate 62 of the second buffer member 66, which is located in the first groove, is fixedly connected to the lower groove surface of the first groove. The bottom of the second upper spring 64 and the top of the second lower spring 65 of the second buffer member 66, which is located in the first groove, respectively abut against the top of the landing bracket 7.
[0034] In this embodiment, the landing support 7 consists of four links. Each link has extension blocks at both ends with opposite extension directions. The extension block at the top of the link has a through hole that is slidably connected to the slide rod 63, and the extension block at the bottom of the link has a through hole that is slidably connected to the shock-absorbing landing foot 8.
[0035] In this embodiment, the shock-absorbing landing foot 8 includes a landing foot 81 and a fixing block 82. The fixing block 82 is fixed to the top of the landing foot 81. A second groove is provided on the inner side of the fixing block 82, and the second buffer 6 is fixed in the second groove.
[0036] In this embodiment, the second upper plate 61 of the second buffer member 6 disposed in the second groove is fixedly connected to the upper groove surface of the second groove, the second lower plate 62 of the second buffer member 6 disposed in the second groove is fixedly connected to the lower groove surface of the second groove, the slide rod 63 of the second buffer member 6 disposed in the second groove passes through the through hole on the extension block at the bottom of the connecting rod, and the second upper spring 64 and the second lower spring 65 of the second buffer member 6 disposed in the second groove abut against the bottom of the connecting rod.
[0037] In this embodiment, the second upper spring 64, the second lower spring 65, and the slide rod 63 of the second buffer member 6 disposed in the second groove can all be directly fixedly connected to the second groove.
[0038] In this embodiment, the bottom of the shock-absorbing landing foot 8 is provided with a shock-absorbing pad; this is used to perform initial shock absorption on the shock-absorbing landing foot 8, while increasing the friction between the shock-absorbing landing foot 8 and the ground.
[0039] The specific usage method of the landing buffer device for a water-washing drone in this embodiment is as follows: When the drone 1 lands, the shock-absorbing landing foot 8 first contacts the ground, and the shock-absorbing pad first reduces part of the impact force of the ground on the drone 1. Then, the landing bracket 7, under the action of the second buffer 66 in the first groove and the second groove respectively, offsets most of the impact force. Finally, the drone 1, under the action of the first buffer 5 in the first groove, offsets part of the impact force, thereby reducing the impact force of the drone 1 when it lands and extending the service life of the drone 1. At the same time, when the drone 1 lands, the pure water in the water tank 4 will continuously shake, causing the drone 1 to be unstable. The first shock-absorbing component can reduce the impact of the pure water shaking in the water tank 4 on the stability of the drone 1.
