Description

Technical Field

[0001] This utility model relates to insulator cleaning equipment, specifically a cleaning brush guide device. Background Technology

[0002] Insulators play a crucial role in power systems, ensuring insulation between power transmission lines and supporting structures such as towers, thus guaranteeing the safe and stable operation of the power system. However, insulators exposed to the outdoor environment for extended periods are susceptible to contaminants such as dust, oil, bird droppings, and salt. These contaminants can reduce the insulation performance of the insulators and, in severe cases, may lead to insulator flashover faults, affecting the reliability of power supply. Traditional insulator cleaning methods mainly include manual wiping and water rinsing, but these methods suffer from problems such as low efficiency, high labor intensity, difficulty in cleaning complex insulator structures, potential damage to the insulators, and operational difficulties in certain special environments (such as mountainous areas and high-voltage towers).

[0003] Several design schemes for insulator cleaning devices have been proposed. One scheme involves a fixed cleaning brush, with different parts of the insulator being cleaned by rotating the cleaning device. Another scheme involves cleaning brushes set along a specific trajectory on the cleaning device, with cleaning achieved by driving the brushes to move around the insulator. In the latter scheme, the cleaning brushes are typically fixed to a telescopic mechanism. However, when the telescopic mechanism extends, the cleaning brushes lack stable support and are prone to wobbling during use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cleaning brush guide device to improve the stability of the cleaning brush during use.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cleaning brush guiding device, including an arc-shaped guide rail mechanism and a slide seat movably disposed on the guide rail mechanism. The motor of the cleaning brush is fixed on the slide seat. A constraint guide wheel is provided on each side of the slide seat. The wheel axle of the constraint guide wheel extends toward the guide rail mechanism, so that the two constraint guide wheels are respectively located on both sides of the guide rail mechanism. An annular groove is provided on the circumferential surface of the constraint guide wheel. The annular groove engages with both sides of the guide rail mechanism, so that the slide seat is supported on the guide rail mechanism by the constraint guide wheel.

[0006] The guide rail mechanism includes a guide rail plate and a base fixed to one side of the guide rail plate, and the annular groove of the constraint guide wheel engages with the side of the guide rail plate.

[0007] An arc-shaped groove extending along its arc length is provided on the guide rail plate, and the drive shaft of the motor passes through the arc-shaped groove.

[0008] The drive shaft has a positioning guide wheel on one side that passes through the arc-shaped groove, and the base has a guide groove that cooperates with the positioning guide wheel.

[0009] The two ends of the arc-shaped groove are provided with mechanical limiting mechanisms to restrict the movement position of the drive shaft.

[0010] Sensors for detecting the movement position of the cleaning brush are provided at both ends of the arc-shaped groove.

[0011] The base includes two arc-shaped side plates connected to the guide rail plate. The arc-shaped cavity formed between the two arc-shaped side plates is connected to the arc-shaped groove above. The drive shaft passes through the arc-shaped groove into the arc-shaped cavity.

[0012] The lower ends of the two arc-shaped side plates protrude toward the arc-shaped cavity, forming guide grooves that cooperate with the positioning guide wheel.

[0013] The arc-shaped cavity is provided with an arc-shaped rack that is fixedly connected to an arc-shaped side plate on one side, and the drive shaft is provided with a drive gear that cooperates with the arc-shaped rack.

[0014] One end of the drive shaft of the motor extends upward through the motor, and the other end extends downward through the arc-shaped groove. Brush heads are provided at both ends of the drive shaft.

[0015] The beneficial effects of this invention are as follows: the motor of the cleaning brush is movably mounted on the guide rail mechanism via a slide block, and the constraint guide wheels on the slide block engage with both sides of the guide rail mechanism, supporting the slide block and the cleaning brush on the guide rail mechanism. The cleaning brush is always supported and constrained by the constraint guide wheels and the guide rail mechanism during movement, ensuring stability during use. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. The specific contents listed in the following embodiments are not limited to the technical features necessary to solve the technical problem described in the claims. Furthermore, the listed embodiments are merely a part of this utility model, and not all of them.

[0020] like Figure 1 As shown, the cleaning brush guiding device of this utility model includes a guide rail mechanism 1 and a slide 2. The guide rail mechanism 1 is arc-shaped, enabling it to guide the cleaning brush to move along the circumference of the insulator to be cleaned. The slide 2 is mounted on the guide rail mechanism and can move along the guide rail mechanism. The motor 4 of the cleaning brush 3 is fixed on the slide, and a brush head (not shown in the figure) is mounted on the drive shaft 401 of the motor 4. As the motor 4 moves along the guide rail mechanism 1 with the slide 2, the brush head cleans the circumferential surface of the insulator.

[0021] like Figure 1 and 2 As shown, a constraint guide wheel 5 is provided on each side of the slide 2. The axle of the constraint guide wheel extends toward the guide rail mechanism 1 (extending downwards in the figure), so that the two constraint guide wheels 5 are located on both sides of the guide rail mechanism 1. An annular groove 501 is provided on the circumferential surface of the constraint guide wheel. The annular groove 501 engages with both sides of the guide rail mechanism, so that the slide 2 is supported on the guide rail mechanism by the constraint guide wheel 5, and can move along the guide rail mechanism by being guided by the engagement of the constraint guide wheel 5 with the guide rail mechanism.

[0022] exist Figure 1 and 2 In the illustrated embodiment, the guide rail mechanism 1 includes a guide rail plate 101 and a base 102. The annular groove 501 of the constraint guide wheel 5 engages with the side of the guide rail plate 101. The base 102 is fixed to one side of the guide rail plate, specifically the lower side of the guide rail plate in this embodiment. The base 102 includes two arc-shaped side plates 1021, the upper ends of which are connected to the guide rail plate 101, and the lower ends extend downwards, forming an arc-shaped cavity 1022 between the two arc-shaped side plates. The guide rail plate 101 has an arc-shaped groove 103 extending along its arc length direction. The arc-shaped groove 103 communicates with the upper part of the arc-shaped cavity 1022. The drive shaft 401 of the motor 4 passes through the arc-shaped groove 103 and enters the arc-shaped cavity 1022. A positioning guide wheel 6 is provided on the side where the drive shaft 401 passes through the arc-shaped groove, and a guide groove 104 that engages with the positioning guide wheel 6 is provided on the base 102. The guide groove 104 can be formed by a protruding portion of the inner wall of the arc-shaped cavity 1022. For example, a flange protruding towards the arc-shaped cavity 1022 can be provided at the lower end of the two arc-shaped side plates 1021 to form a guide groove 104 that cooperates with the positioning guide wheel. The positioning guide wheel cooperates with the guide groove to play the role of positioning and bearing radial force.

[0023] The drive shaft 401 of motor 4 passes through the arc-shaped cavity 1022 of base 102 and continues to extend, passing through the guide rail mechanism 1, and then a fixed brush head is installed on its protruding part. For example... Figure 1 As shown, the drive shaft 401 can pass through both the motor 4 and the guide rail mechanism 1. One end of the drive shaft of the motor 4 extends upward through the motor, and the other end extends downward through the arc-shaped groove 103. Brush heads 301 are provided at both ends of the drive shaft. In this case, the drive motor is positioned in the middle, and the cleaning heads are located on both sides of the motor. Of course, if needed, the drive shaft 401 can also extend in only one direction and connect to the brush head.

[0024] like Figure 1 and 2 As shown, an arc-shaped rack 9 is fixedly installed inside the arc-shaped cavity 1022, and the arc-shaped rack 9 is fixedly connected to one of the arc-shaped side plates 1021. A drive gear 10 is installed on the drive shaft 401, and the drive gear 10 meshes with the arc-shaped rack 9. When the motor 4 drives the brush head to rotate through the drive shaft 401, the rotating drive shaft can drive the drive gear 10 to rotate. Since the arc-shaped rack 9 is fixed, the drive gear 10 meshing with it will move along the arc-shaped rack 9 when it rotates, so that under the action of the arc-shaped rack 9, the drive gear drives the motor 4 and the brush head to move along the guide rail mechanism 1. Through this structure, the motor can simultaneously drive the cleaning brush 3 to revolve around the insulator and rotate its own brush head to complete the cleaning of the circumference of the insulator. The arc-shaped rack 9 can be set on the outer ring as shown in the figure, and the drive gear 10 meshes with the teeth on the inner arc surface of the arc-shaped rack 9. Alternatively, the arc-shaped rack can be set on the inner ring, and the drive gear meshes with the teeth on the outer arc surface of the arc-shaped rack.

[0025] like Figure 1 As shown, the guide rail mechanism 1 has mechanical limiting mechanisms 7 at both ends of the arc-shaped groove 103, such as buffer pads fixed to the ends of the arc-shaped groove 103. The maximum travel of the cleaning brush 3 is limited by the mechanical limiting mechanisms. The guide rail mechanism 1 is also equipped with sensors 8 for detecting the moving position of the cleaning brush 3. The sensors 8 can be proximity switches or similar devices, and are respectively arranged at both ends of the arc-shaped groove 103. When the cleaning brush 3 moves to a predetermined position along the arc-shaped groove 103, the sensors 8 detect the cleaning brush 3 and transmit the detection signal to the controller. The controller then controls the motor of the cleaning brush 3 to reverse, causing the cleaning brush 3 to move in the opposite direction.

[0026] As the cleaning brush 3 revolves around the insulator and rotates on its own axis under the guidance of the guide rail mechanism 1, the two superimposed movements generate an outward parabolic curve. This not only provides a good cleaning effect but also eliminates cleaning dead spots. Since the cleaning brush rotates clockwise and counterclockwise around the insulator, its rotation is not constant and can rotate in both directions. This eliminates the problem of some brush heads being deformed on one side due to constant pressure, which could lead to irreversible deformation.

[0027] The above description of specific embodiments is only for the purpose of helping to understand the technical concept and core idea of ​​this utility model. Although specific preferred embodiments have been used to describe and illustrate the technical solution, they should not be construed as limiting the utility model itself. Those skilled in the art can make various changes in form and detail without departing from the technical concept. These easily conceived changes or substitutions should all be covered within the protection scope of this utility model.
