Abstract
Description
Technical Field
[0001] This invention relates to a device for segmenting and investigating line losses in power distribution areas and its usage method, belonging to the field of power maintenance equipment. Background Technology
[0002] When inspecting power transmission line damage, the equipment is usually mounted on the power transmission line using wheelsets and slid along the line so that the camera on the equipment can be used to observe whether there is any damage to the power transmission line.
[0003] In northern winters, snow accumulates on the upper part of power transmission lines, causing them to bear a heavy load. The snow also obscures the lines, making it difficult to observe surface damage during routine inspections. In late winter and early spring, the large temperature difference between day and night, with rising daytime temperatures causing some snow to melt and nighttime temperatures dropping below zero, causes the melted snow to form an ice layer on the surface of the power transmission lines. This also hinders inspections and is extremely difficult to handle. Therefore, it is necessary to improve these methods. Summary of the Invention
[0004] The purpose of this invention is to solve the above-mentioned problems existing in the background art by providing a transformer substation line loss segmentation and investigation device and its usage method.
[0005] The present invention achieves the above objectives by adopting the following technical solution: A device for segmenting and investigating line loss in a transformer substation includes a frame, a connecting frame, and two cleaning devices. The frame has an opening on one side, a cross groove on the side of the frame near the opening, and a slide rail on the inner wall of the side of the frame away from the opening. The connecting frame is interference-fitted with the slide rail. One side of each of the two cleaning devices is fixedly connected to the connecting frame, and the other side is slidably fitted with the cross groove.
[0006] A method for using a transformer substation line loss segmentation and investigation device, the method comprising the following steps: Step 1: Move the frame to the side of the corresponding power line using a drone, then move the drone laterally so that the power line passes through the opening and moves between the two cleaning devices; Step 2: Control the drone to move upwards. The drone will drive the frame upwards, causing the two cleaning devices and power lines to move downwards relative to the frame and disengage from the opening. Step 3: Start the motor and control the drone to fly along the direction of the power line to clear the snow and ice covering it. Compared with the prior art, the advantages of this invention are: this invention can not only clear the snow on the power line, but also, through the movement of the movable rod, pierce the ice layer, causing it to break, and shake it off through vibration to ensure normal inspection.

Detailed Implementation
[0008] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0009] Specific implementation method one: as follows Figure 1-10 As shown in the figure, this embodiment describes a transformer area line loss segmentation and inspection device, including a frame 1, a connecting frame 2, and two cleaning devices 3; one side of the frame 1 is provided with an opening 18, a cross groove 17 is provided on the side frame near the opening 18, and a slide rail 13 is provided on the inner wall of the side frame away from the opening 18; the connecting frame 2 is interference-fitted with the slide rail 13; one side of the two cleaning devices 3 is fixedly connected to the connecting frame 2, and the other side is slidably fitted with the cross groove 17.
[0010] Each cleaning device 3 includes a slider 32; the slider 32 slides in conjunction with the cross groove 17, and a shaft 33 is connected inside the slider 32 via a bearing; one end of the shaft 33 is connected to the side of the connecting frame 2 via a bearing, and the other end of the shaft 33 is fixedly connected to the output shaft of the motor 31; multiple rollers 331 are provided on the outer circular surface of the shaft 33, and the rollers 331 contact the inner circular surface of the inner cylinder 35; one end of the inner cylinder 35 is fixedly connected to the connecting frame 2; a limit rod I 343 is fixedly connected to the outer wall of the inner cylinder 35, and the other end of the limit rod I 343 is fixedly connected to the inner wall of the outer cylinder 34. Driven by a drone, the outer cylinder 34 cleans the snow accumulated on the power transmission line 4.
[0011] Multiple centrally symmetrical arc-shaped strips 332 are fixedly connected to the outer circular surface of the shaft 33; both the inner cylinder 35 and the outer cylinder 34 are provided with through holes, and movable rods 352 that slide with them are provided in the through holes; the movable rods 352 are provided with through grooves 353, and elastic telescopic rods 355 are fixedly connected to the inner wall of the through grooves 353 near the shaft 33; the free end of the elastic telescopic rods 355 is fixedly connected to a connecting rod 354 that slides with the through grooves 353; both ends of the connecting rods 354 are fixedly connected to the inner wall of annular baffles 356 that are sleeved on the outside of the movable rods 352. By repeatedly moving the movable rods 352, the free end of the movable rods 352 strikes the power transmission line 4, causing it to vibrate and shake off some of the accumulated snow and ice.
[0012] The limiting rod I 343 is a telescopic rod with an elastic reset component, which is always in a compressed state; the limiting rod II 341 is fixedly connected to the inner wall of the outer cylinder 34, and the limiting rod II 341 is arranged opposite to the movable rod 352.
[0013] The movable rod 353 has a wheel 351 at one end near the shaft 33. The wheel 351 contacts the outer circular surface of the arc-shaped strip 332 and the shaft 33. The wheel 351 reduces the wear and tear on the arc-shaped strip 332, the shaft 33, and the movable rod 352.
[0014] When the baffle 356 abuts against the inner wall of the outer cylinder 34, the elastic telescopic rod 355 is in a compressed state.
[0015] When the wheel 351 contacts the arc-shaped bar 332, the movable rod 352 moves away from the shaft 33.
[0016] The lower end of the connecting frame 2 is fixedly connected to an electromagnet I 21, and an electromagnet II 14 that cooperates with the electromagnet I 21 is provided in the slide rail 13 inside the frame 1; a power supply 16 is fixedly connected to the bottom of the frame 1, and a protective shell 15 is provided on the outside of the power supply 16; a support rod 22 is fixedly connected to the side of the connecting frame 2.
[0017] The upper end of the frame 1 is provided with a connecting ring 11, and a transmission rod 12 is provided on the connecting ring 11 and can rotate relative to the connecting ring 11; the upper end of the transmission rod 12 is connected to the bottom of the drone.
[0018] A method for using a transformer substation line loss segmentation and investigation device, the method comprising the following steps: Step 1: Move the frame 1 to the side of the corresponding power line 4 using the drone, and then move the drone laterally so that the power line 4 passes through the opening 18 and moves between the two cleaning devices 3. Step 2: Control the drone to move upward. The drone will drive the frame 1 to move upward, causing the two cleaning devices 3 and the power transmission line 4 to move downward relative to the frame 1 and disengage from the opening 18. Step 3: Start motor 31 and control the drone to fly along the set direction of power line 4 to clear the snow and ice layer 5 covering power line 4.
[0019] The working principle of this invention is as follows: When using this device, the drone drives the frame 1 to move to the side of the corresponding power line 4, and then moves the drone laterally so that the power line 4 passes through the opening 18 and moves between the two cleaning devices 3 (the gap between the two outer cylinders 34 is the same as the diameter of the power line 4). Control the drone to move upward, the drone drives the frame 1 to move upward, so that the two cleaning devices 3 and the power transmission line 4 move downward relative to the frame 1, that is, the sliders 32 on the two cleaning devices 3 move into the cross groove 17 and disengage from the opening 18. Start motor 31 and control the drone to fly along the direction set by power transmission line 4. During the drone's flight, because the elastic reset component inside limit rod I 343 is in a compressed state and neither the outer cylinder 34 nor the inner cylinder 35 can rotate, therefore... Figure 1 In the state shown (the limiting rod I 343 of each cleaning device 3 pushes the outer cylinder 34 towards the direction of the support rod 22, so that the distance between the two outer cylinders 34 is fixed and they are attached to the outer surface of the power transmission line 4), the drone flies and drives the cleaning device 3 to move together to clean the snow covering the power transmission line 4. Simultaneously, after the motor 31 starts, it drives the shaft 33 to rotate. The shaft 33 then drives the arc-shaped strips 332 on its outer surface to rotate together. Since there are multiple arc-shaped strips 332 arranged in a centrally symmetrical manner, when the shaft 33 rotates, the multiple arc-shaped strips 332 will contact the wheel 351 respectively, pushing the wheel 351 to move. This causes the wheel 351 to drive the corresponding movable rod 352 to move away from the shaft 33. Figure 8In the state shown, the baffle 356 is blocked by the outer cylinder 34 and cannot move further downward, which compresses the elastic telescopic rod 355, and causes the end of the movable rod 352 away from the shaft rod 33 to strike the power transmission line 4, causing the power transmission line 4 to vibrate, so as to shake off some of the snow and ice. When encountering ice layer 5, because ice layer 5 covers the outside of transmission line 4, the overall thickness of transmission line 4 and ice layer 5 increases. When outer cylinder 34 moves to the outside of ice layer 5, due to the increased overall thickness of transmission line 4 and ice layer 5, the two outer cylinders 34 move in opposite directions, further compressing the limiting rod I 343, thereby increasing the distance between the two outer cylinders 34 to accommodate the increased thickness of transmission line 4 and ice layer 5. Subsequently, motor 31 drives shaft 33 to rotate, and movable rod 352 moves according to the above process. However, because the distance between the two outer cylinders 34 increases, when movable rod 352 moves away from shaft 33, it will be exposed outside the outer cylinder 34, that is, in contact with the ice layer 5 outside the outer cylinder 34 (e.g., Figure 10 As shown in the diagram, the ice layer 5 is broken by striking it. During the rotation of the shaft 33 driven by the motor 31, the drone's flight speed is slowed down, increasing the dwell time of the movable rod 352 at the position of the ice layer 5, so as to fully contact the ice layer 5 and crush the ice layer. The drone can also hover or move laterally perpendicular to the power line 4 to drive the frame 1, connecting frame 2 and cleaning device 3 to rotate around the power line 4, so as to strike the ice layer 5 on the side of the power line 4, making the ice layer 5 cleared more thoroughly. After the ice layer 5 is broken, the movable rod 352 strikes the power line 4 in the above manner to generate vibration, and the entire ice layer 5 is shaken off, completing the cleaning.
