Description

Technical Field

[0001] This utility model relates to the field of insulator cleaning technology, and in particular to an automatic cleaning device for insulators of power supply and distribution lines. Background Technology

[0002] Pollution flashover is a common accident in power systems. It is mainly caused by the decrease in insulation performance due to the accumulation of dirt on the surface of insulators after they become damp, resulting in flashover. Cleaning insulators can effectively reduce the accumulation of dirt on the surface, thereby reducing the probability of pollution flashover accidents and ensuring the safe and stable operation of power lines and equipment. Cleaning insulators requires the use of cleaning devices.

[0003] Existing cleaning devices mostly use brushes to clean insulators. To ensure that the upper and lower adjacent ceramic insulating discs on the insulator can be cleaned simultaneously at one time, the components for installing the brushes are mostly placed between the upper and lower ceramic insulating discs. However, the brush mounting components are mostly integrated and fixed to the structure on which they are installed. This results in the brushes being restricted to the narrow and cramped space between the two ceramic insulating discs, making it inconvenient to disassemble and replace them. Utility Model Content

[0004] In view of this, the present invention provides an automatic cleaning device for insulators of power supply and distribution lines to solve the problem that cleaning brushes are inconvenient to disassemble and replace.

[0005] The technical solution proposed by this utility model is: an automatic cleaning device for insulators of power supply and distribution lines, specifically including a U-shaped retaining frame, wherein the U-shaped retaining frame is rotatably installed on the insulator, and the insulator is integrally formed by a row of ceramic insulating discs and a column core at the center position;

[0006] A row of cleaning plates is inserted through the U-shaped retaining frame at equal intervals. Brushes are fixed on both the upper and lower sides of the main body of the cleaning plate. The main body is inserted between two adjacent ceramic insulating discs. The two brushes rub against the opposite side of the two ceramic insulating discs. Two sliding components are symmetrically slidably installed on the U-shaped retaining frame. The sliding components are composed of three U-shaped sliding sleeves and four vertical connecting rods symmetrically fixed between the three. A row of T-shaped positioning parts is fixed to the two sliding components at equal intervals. The vertical insertion shaft of the T-shaped positioning part is inserted and engaged with the protruding part of the tail end of the cleaning plate of the corresponding height.

[0007] Furthermore, the tail end of the cleaning plate is integrally formed with two symmetrically arranged limiting blocks. The vertical support side plate of the U-shaped retaining frame has a row of assembly slots that are adapted to the shape of the limiting blocks at equal intervals. The two limiting blocks are inserted into the assembly slots of corresponding heights.

[0008] Furthermore, the U-shaped sliding sleeve slides into the edge of the vertical support side plate of the U-shaped retaining frame, and the two ends of the horizontal part of the T-shaped positioning member are respectively fixedly connected to two vertical connecting rods or two U-shaped sliding sleeves at corresponding positions.

[0009] Furthermore, a tightening bolt is threaded through and installed on one of the upper U-shaped sliding sleeves, with the head end of the tightening bolt abutting against the vertical support side plate of the U-shaped retaining frame.

[0010] Furthermore, a driven gear ring is fixedly provided on the U-shaped retaining frame, and the driven gear ring is concentrically arranged with the column core.

[0011] Furthermore, rotating rings are fixedly connected to the two horizontal side plates of the U-shaped retaining frame, and the two rotating rings are rotatably engaged with the upper and lower ends of the column core.

[0012] The swivel consists of two semicircular rings bolted together, with one of the semicircular rings fixedly connected to the first end of the horizontal side plate of the U-shaped retaining frame.

[0013] Furthermore, an L-shaped support rod is fixedly installed on the insulator, with the first end of the L-shaped support rod fixedly connected to the top part of the column core, and a motor fixedly suspended at its tail end;

[0014] A drive gear is fixedly mounted on the motor shaft, and the drive gear meshes with the driven gear ring for transmission.

[0015] The automatic cleaning device for insulators of power supply and distribution lines provided by this utility model has the following beneficial effects:

[0016] 1. The cleaning plate is the brush mounting component, and the U-shaped retaining frame is the mounting structure for the brush mounting component. The cleaning plate is installed by sliding through and fitting into the U-shaped retaining frame. When the vertical insertion shaft of the T-shaped positioning piece is inserted into the protruding part at the tail end of the cleaning plate, the cleaning plate can be positioned on the sliding component. The cleaning plate can be released simply by sliding the T-shaped positioning piece away from the cleaning plate, allowing it to be pulled out from the narrow space between the U-shaped retaining frame and the two adjacent ceramic insulating discs. This allows for simple and quick tearing, disassembly, and replacement of the brush. Compared to the existing technology of integrating and fixing the brush mounting component to the mounting structure, this avoids the brush being restricted in the narrow space between the two adjacent ceramic insulating discs along with the integrated and fixed brush mounting component, which would hinder the tearing and disassembly of the brush. This helps to improve the convenience of brush disassembly and replacement operations.

[0017] Second, a row of T-shaped positioning pieces and two sliding components together form a sliding kit. Simply sliding this sliding kit up and down will drive the row of T-shaped positioning pieces to slide up and down synchronously, and control the vertical insertion shaft of the row of T-shaped positioning pieces to synchronously insert and release with the row of cleaning plates. This efficiently completes the insertion, locking and unlocking operations of the row of cleaning plates in one go. This eliminates the trouble of locking and unlocking the row of cleaning plates step by step before and after replacing the brushes, which is convenient to operate and helps to simplify the brush replacement process as a whole.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] Please refer to Figures 1 to 6 Example 1:

[0037] This embodiment proposes an automatic cleaning device for power supply and distribution line insulators, including a U-shaped retaining frame 2, which is rotatably mounted on the insulator 1. The insulator 1 is integrally formed by a row of ceramic insulating discs 102 and a column core 101 at the center position.

[0038] A row of cleaning plates 6 are inserted through the U-shaped retaining frame 2 at equal intervals. Brushes 602 are fixed to the upper and lower sides of the main body of the cleaning plate 6 by Velcro. The main body is inserted between two adjacent ceramic insulating discs 102. The two brushes 602 respectively rub against the opposite side of the two ceramic insulating discs 102. Two sliding components 5 are symmetrically slidably installed on the U-shaped retaining frame 2. The sliding components 5 are composed of three U-shaped sliding sleeves 501 and four vertical connecting rods 502 symmetrically fixed between the three. A row of T-shaped positioning parts 503 are fixed to the two sliding components 5 at equal intervals. The vertical insertion shaft of the T-shaped positioning part 503 is inserted and engaged with the protruding part of the tail end of the cleaning plate 6 at the corresponding height.

[0039] Preferably, the tail end of the cleaning plate 6 is integrally formed with two symmetrically arranged limiting blocks 601. The vertical support side plate of the U-shaped retaining frame 2 has a row of assembly slots 203 that are adapted to the shape of the limiting blocks 601 through it in an equidistant manner. The two limiting blocks 601 are inserted and engaged with the assembly slots 203 of the corresponding height.

[0040] Preferably, the U-shaped sliding sleeve 501 is slidably engaged with the edge portion of the vertical support side plate of the U-shaped retaining frame 2, and the two ends of the horizontal portion of the T-shaped positioning member 503 are respectively fixedly connected to two vertical connecting rods 502 or two U-shaped sliding sleeves 501 at corresponding positions.

[0041] Preferably, a tightening bolt 5011 is threadedly installed through a U-shaped sliding sleeve 501 on the upper side, and the head end of the tightening bolt 5011 abuts against the vertical support side plate of the U-shaped retaining frame 2.

[0042] Preferably, a driven gear ring 202 is fixedly provided on the U-shaped retaining frame 2, and the driven gear ring 202 is concentrically arranged with the core 101.

[0043] Preferably, a rotating ring 201 is fixedly connected to each of the two horizontal side plates of the U-shaped retaining frame 2, and the two rotating rings 201 are rotatably engaged with the upper and lower ends of the column core 101. The rotating ring 201 is composed of two semi-circular rings 2011 connected by bolts, and one of the semi-circular rings 2011 is fixedly connected to the first end of the horizontal side plate of the U-shaped retaining frame 2.

[0044] Preferably, an L-shaped support rod 3 is fixedly installed on the insulator 1. The first end of the L-shaped support rod 3 is fixedly connected to the top part of the column core 101, and a motor 4 is fixedly suspended at its tail end. A drive gear 401 is fixedly mounted on the rotating shaft of the motor 4, and the drive gear 401 meshes with the driven gear ring 202 for transmission.

[0045] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0046] The electrical control box 7 is set separately from the insulator 1 and installed far away from the insulator 1. The electrical control box 7 is equipped with a time controller and an intermediate relay for controlling the start and stop of the motor 4. The time controller is electrically connected to the intermediate relay, and the intermediate relay is electrically connected to the motor 4.

[0047] It is worth noting that the U-shaped retaining frame 2 and the auxiliary components installed on it, the cleaning plate 6 and the limit plug 601 are all made of insulating material; the selection of the model of the time controller and the intermediate relay, their installation and wiring methods, and their control principles are all existing technologies for those engaged in the electrical automation transformation, design and maintenance of equipment in this field, so they will not be described in detail here.

[0048] The following section provides a detailed explanation of the working principles, specific details, implementation steps, functions and interrelationships of each feature, and their roles in realizing this technical solution:

[0049] Through the meshing transmission of the driving gear 401 and the driven gear ring 202, the motor 4 can drive the U-shaped retaining frame 2 and the row of cleaning plates 6 mounted on it to rotate around the core 101, cleaning the dust accumulated on the upper and lower end surfaces of the row of ceramic insulating discs 102. When the row of cleaning plates 6 rotates around the core 101, the brushes 602 on its upper and lower sides respectively rub against the upper and lower end surfaces of the row of ceramic insulating discs 102, thereby achieving the sweeping and cleaning of the row of ceramic insulating discs 102.

[0050] The cleaning plate 6 is a brush mounting component, and the U-shaped retaining frame 2 is the mounting structure for the brush mounting component. The cleaning plate 6 is fitted and installed in a through-sliding manner with the U-shaped retaining frame 2. When the vertical insertion shaft of the T-shaped positioning member 503 is inserted and engaged with the protruding part at the tail end of the cleaning plate 6, the cleaning plate 6 can be positioned on the sliding component 5. The cleaning plate 6 can be released simply by sliding the T-shaped positioning member 503 away from the cleaning plate 6, and the cleaning plate 6 can be pulled out from the narrow and confined space between the U-shaped retaining frame 2 and the two adjacent ceramic insulating discs 102. This allows for a simple and quick tearing, disassembly, and replacement of the brush 602. Compared with the existing technology of integrating and fixing the brush mounting component to the mounting structure, this avoids the brush 602 being restricted in the narrow and confined space between the two adjacent ceramic insulating discs 102 along with the integrated and fixed brush mounting component, which would hinder the tearing and disassembly of the brush 602. This helps to improve the convenience of disassembly and replacement of the brush 602.

[0051] A row of T-shaped positioning pieces 503 and two sliding components 5 together form a sliding kit. By simply sliding the sliding kit up and down, the row of T-shaped positioning pieces 503 can be driven to slide up and down synchronously, and the vertical insertion shaft of the row of T-shaped positioning pieces 503 can be controlled to synchronously insert and insert with the row of cleaning plates 6. This efficiently completes the insertion, locking and unlocking operations of the row of cleaning plates 6 in one go. This eliminates the trouble of locking and unlocking the row of cleaning plates 6 step by step before and after replacing the brush 602. The operation is convenient and helps to simplify the replacement steps of the brush 602.

[0052] When the cleaning plate 6 is removed to disassemble and replace the brush 602, the two limiting blocks 601 are pulled away from the assembly slot 203 and the assembly slot 203 is exposed. The brush 602 can pass through the vertical support side plate of the U-shaped retaining frame 2 through the exposed assembly slot 203 and follow the cleaning plate 6 to be removed and disassembled normally and smoothly.

[0053] The working principle of this embodiment is as follows: The time controller can set an intermittent start-stop program, which can control the motor 4 to start once every certain period of time and stop automatically after running for a period of time. This can control the motor 4 to start periodically in the form of intermittent start-stop, and drive the control ring frame 2 and a row of cleaning plates 6 to rotate, automatically sweeping and cleaning the insulator 1.

[0054] The control process for intermittent start-stop of motor 4 is as follows: When the waiting time for motor 4 to stop reaches the preset waiting time of the time controller, the time controller turns on the power of the intermediate relay and controls the intermediate relay to engage. After the intermediate relay engages, it supplies power to motor 4. After motor 4 is powered on, it drives the U-shaped retaining frame 2 and a row of cleaning plates 6 to rotate and clean the insulator 1. When the running time of motor 4 after starting reaches the preset continuous running time of the time controller, the time controller cuts off the power of the intermediate relay. The intermediate relay disconnects and cuts off the power supply to motor 4. Motor 4 stops due to power failure. By repeating this process, the intermittent start-stop control of motor 4 can be achieved.
