Description

Technical Field

[0001] The invention relates to a cleaning device, in particular to an insulator cleaning device. Background Art

[0002] Insulators play a vital role in the power system. They can ensure the insulation between power transmission lines and supporting structures such as poles and towers, and ensure the safe and stable operation of the power system. However, insulators exposed to the outdoor environment for a long time are susceptible to the adhesion of pollutants such as dust, oil, bird droppings, and salt. These pollutants will reduce the insulation performance of the insulators. In severe cases, they may cause faults such as insulator flashover, affecting the reliability of power supply. Traditional insulator cleaning methods mainly include manual wiping and water flushing, but these methods have problems such as low efficiency, high labor intensity, difficulty in cleaning insulators with complex structures, possible damage to insulators, and difficulty in operation in certain special environments (such as mountainous areas and high-voltage line towers).

[0003] There are several forms of insulator cleaning device design schemes that have been proposed so far. One form is that the cleaning brush head is fixedly arranged, and the cleaning of different parts of the insulator is achieved by rotating the cleaning device. Another form is that the cleaning brush head is arranged on the cleaning device according to a specific motion track, and the cleaning of different parts of the insulator is achieved by driving the cleaning brush head to move around the insulator. In the method of driving the cleaning brush head to move, independent power sources are used to drive the movement of the cleaning brush head and the rotation of the cleaning brush head itself. The cleaning brush head is usually arranged on a retractable mechanism and driven by a fixed power source. On the one hand, this structure has more power sources, is heavy, and is not convenient for handheld use. On the other hand, the telescopic mechanism does not provide sufficient support for the cleaning brush head, and it is easy to shake during use. Summary of the invention

[0006] The driving shaft passes through the arc guide rail mechanism and is fixedly connected to the driving gear, and cleaning heads are connected to both ends of the driving shaft.

[0007] The driving motor is an outer rotor brushless DC motor, the driving shaft passes through the driving motor and is driven to rotate by the driving motor.

[0008] The driving motor is arranged on a motor seat, and a restraining guide wheel cooperating with the arc guide rail mechanism is arranged on the motor seat.

[0010] One end of the driving shaft passing through the guide rail plate is provided with a positioning guide wheel, and the base is provided with a guide groove matched with the positioning guide wheel.

[0011] Position sensors for limiting the moving position of the cleaning mechanism are provided at both ends of the arc guide mechanism, and the position sensors are connected to a controller for controlling the reversing of the driving motor.

[0012] The arc-shaped guide rail mechanism is provided with a conductive rail for supplying power to the drive motor, and the motor seat of the drive motor is provided with a conductive wheel connected to the wiring port of the drive motor and matched with the conductive rail.

[0013] The supporting component is provided with two cleaning components, which are rotatably connected to the supporting component, so that the cleaning components can be folded together by rotation to surround the insulator, or separated from the insulator by rotation to separate.

[0014] The supporting component includes a connecting seat and a supporting rod. The connecting seat is fixed at one end of the supporting rod and is rotatably connected to the cleaning component. A first slider is provided at one end of the supporting rod close to the connecting seat and is connected to the cleaning component through a first connecting rod to drive its rotation. A second slider is also provided on the supporting rod and is connected to the first slider through a second connecting rod.

[0015] The beneficial effects of the present invention are: the driving motor of the cleaning mechanism is used to drive the cleaning head to rotate on the one hand, and on the other hand, the driving gear and the arc-shaped rack are used to drive the cleaning mechanism to move along the arc-shaped guide rail mechanism. One driving motor is used to simultaneously realize the self-rotation of the cleaning head and the revolution along the arc-shaped guide rail mechanism, thereby reducing the use of motors and reducing the weight of the equipment. The cleaning mechanism can always be supported by the arc-shaped guide rail mechanism during the movement process, thereby ensuring the stability of the cleaning mechanism during the insulator cleaning process.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings and specific implementation methods. The specific contents listed in the following embodiments are not limited to the technical features necessary for the technical problems to be solved by the technical solutions recorded in the claims. At the same time, the enumerated embodiments are only part of the present invention, not all embodiments.

[0024] like Figure 1 As shown, the insulator cleaning device of the present invention comprises a supporting component 1 and a cleaning component 2. The supporting component 1 is used to support the cleaning component 2 so that the cleaning component 2 can reach the position of the insulator to be cleaned. In the illustrated embodiment, the main body of the supporting component 1 is a supporting rod 102, and a connecting seat 101 is fixed at one end of the supporting rod 102. The cleaning component 2 is installed on the connecting seat 101 to clean the insulator. In order to clean various parts of the circumference of the insulator, the cleaning component 2 is preferably able to surround the insulator, such as Figure 1 and 2In the illustrated embodiment, two cleaning components 2 are rotatably connected to the connection seat 101 of the support component, so that the cleaning components can be closed by rotation to surround the insulator, or separated by rotation to separate from the insulator. The closing degree of the two cleaning components 2 is controlled as required to adapt to insulators of different sizes.

[0025] like Figure 1 and 2 As shown, the cleaning components 2 are each connected with a first connecting rod 103, and the first slider 104 at one end of the support rod 102 near the connecting seat can be, for example, in the form of a sliding sleeve on the support rod. One end of the first connecting rod 103 is connected to the first slider 104, and the other end is connected to the cleaning component 2. When the first slider 104 moves, the cleaning component 2 can be driven to deflect by the first connecting rod 103. In order to facilitate the rotation of the cleaning component 2, a swing arm connected to the first connecting rod 103 can be provided on the cleaning component 2. A second slider 106 is provided on the support rod, and the second slider 106 is connected to the first slider through the second connecting rod 105. The second slider 106 can be arranged at a position close to the handheld position on the support rod, so as to facilitate the closing and opening of the cleaning component 2 by the second slider 106. A handle that is convenient for people to operate can be provided on the second slider 106, and a locking mechanism that locks the position after being adjusted in place can also be provided, such as a locking bolt or other compression locking structure.

[0026] like Figure 2 As shown, the cleaning component 2 includes an arc-shaped guide rail mechanism 3 and a cleaning mechanism 4, wherein the arc-shaped guide rail mechanism 3 is rotatably connected to the supporting component, and the cleaning mechanism 4 is arranged on the arc-shaped guide rail mechanism 3 and can move along the arc-shaped guide rail mechanism. After the arc-shaped guide rail mechanism 3 surrounds the insulator, the cleaning mechanism 4 is controlled to move along the arc-shaped guide rail mechanism to clean various circumferential parts of the insulator.

[0027] like Figure 1 , 2As shown in Figure 3, the cleaning mechanism includes a cleaning head 401, a drive motor 402 and a drive shaft 403 driven by the drive motor. In the illustrated embodiment, the drive shaft 403 is coaxial with the motor shaft of the drive motor 402, is an extension of the motor shaft, or is coaxially connected to the motor shaft. The cleaning head 401 can be a brush head with a brush, which is fixedly or detachably mounted on the drive shaft. The cleaning head 401 is driven to rotate by the drive shaft 403 to clean the insulator. In the illustrated embodiment, the drive shaft 403 passes through the drive motor and is driven to rotate by the drive motor. The drive motor 402 adopts an outer rotor brushless DC motor, which has the characteristics of high torque and low speed. In addition to ensuring that sufficient power is provided to drive the cleaning head to rotate, the weight and volume are reduced as much as possible to achieve miniaturization and lightweight of the product. In an embodiment without drawings, the drive shaft can be set independently of the motor shaft of the drive motor 402, but another transmission component is added, such as a gear pair that transmits between the motor shaft and the drive shaft.

[0028] like Figure 3 As shown in FIG. 5 , a driving gear 6 is also fixedly connected to the driving shaft 403, and an arc-shaped rack 5 extending along the arc length direction is fixedly installed in the arc-shaped guide mechanism 3. The driving gear is meshed with the arc-shaped rack, and the driving motor drives the cleaning head 401 to rotate through the driving shaft, while the rotating driving shaft can drive the driving gear 6 to rotate. Since the arc-shaped rack 5 is fixed, the driving gear 6 meshed with it will move along the arc-shaped rack 5 when it rotates, so that under the action of the arc-shaped rack 5, the driving gear drives the cleaning mechanism 4 to move along the arc-shaped guide mechanism 3. Through this structure, the driving motor can simultaneously drive the cleaning mechanism 4 to revolve around the insulator and the self-rotation of its own cleaning head to complete the cleaning of the circumference of the insulator. The arc-shaped rack 5 can be set on the outer ring as shown in the figure, and the driving gear 6 is meshed with the teeth on the inner arc surface of the arc-shaped rack 5. The arc-shaped rack 5 can also be set on the inner ring, and the driving gear 6 is meshed with the teeth on the outer arc surface of the arc-shaped rack 5.

[0029] The arc guide mechanism 3 includes a guide plate 301 and a base 302 fixed below the guide plate, the base includes two arc side plates connected to the bottom of the guide plate 301, and an arc cavity formed between the two arc side plates. The cleaning mechanism 4 is arranged above the guide plate 301. The "above" and "below" mentioned above are the directions shown in the figure, which do not limit the direction of the actual product. In actual application, they can be reversed. The guide plate 301 is provided with an arc groove 303 for the drive shaft to pass through. The arc groove 303 is connected to the top of the arc cavity, and the drive shaft passes into the arc cavity from the arc groove. The arc rack 5 is fixed to the inner wall of the arc cavity by locating pins, screws and other structures. The driving gear 6 on the driving shaft 403 is located in the arc cavity and meshes with the arc rack 5.

[0030] like Figure 3As shown in FIG. 5 , the driving motor 402 is arranged on the motor seat 404, and a constraint guide wheel 7 is respectively provided on both sides of the motor seat. The wheel axle of the constraint guide wheel extends toward the arc guide rail mechanism 3, so that the two constraint guide wheels are respectively located on both sides of the arc guide rail mechanism 3. An annular groove is provided on the circumferential surface of the constraint guide wheel, and the annular groove is engaged with both sides of the guide rail plate 301 of the arc guide rail mechanism 3. The motor seat 404 is supported above the guide rail plate 301 by the constraint guide wheel 7, and can be guided to move along the arc guide rail mechanism 3 by the cooperation between the constraint guide wheel 7 and the guide rail plate 301.

[0031] like Figure 4 and 5 As shown, one end of the driving shaft 403 passing through the guide rail plate 301 is provided with a positioning guide wheel 8, and the base 302 is provided with a guide groove 304 that cooperates with the positioning guide wheel 8. Specifically, the lower ends of the two arc-shaped side plates can be arranged to protrude toward the arc-shaped cavity to form a guide groove 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.

[0032] The driving shaft 403 of the cleaning mechanism 4 continues to extend after passing through the arc-shaped guide rail mechanism 3, and after passing through the arc-shaped guide rail mechanism 3, a cleaning head 401 is fixedly mounted on the passing part. Figure 4 As shown, the drive shaft 403 can pass through the drive motor 402 and the arc guide mechanism 3 at the same time, and the cleaning heads 401 are connected to both ends of the drive shaft. In this case, the drive motor is placed in the middle, and the cleaning heads are located on both sides of the motor. Of course, as needed, the drive shaft 403 can also pass through only one direction and connect the cleaning head.

[0033] like Figure 2 and 3 As shown, mechanical limit mechanisms are provided at both ends of the arc groove 303 of the arc guide mechanism 3, for example, buffer pads fixed at the ends of the arc groove 303 are used. The maximum movement stroke of the cleaning mechanism 4 is limited by the mechanical limit mechanism. The arc guide mechanism 3 is also provided with a position sensor 9 for detecting the moving position of the cleaning mechanism 4. The position sensor 9 can be a proximity switch or a device with similar functions, which is arranged at both ends of the arc groove 303. When the cleaning mechanism 4 moves to a predetermined position along the arc groove 303, the position sensor 9 detects the cleaning mechanism 4 and transmits the detection signal to the controller, which controls the driving motor of the cleaning mechanism 4 to commutate, so that the cleaning mechanism 4 moves in the reverse direction.

[0034] like Figure 2 , 3As shown in Figure 5, the arc guide mechanism 3 is provided with a conductive rail 10 for supplying power to the drive motor, and the motor seat of the drive motor is provided with a conductive wheel 11, which is connected to the wiring port of the drive motor on the one hand and contacts and cooperates with the conductive rail on the other hand. The conductive rails 10 on the arc guide mechanism 3 are two arranged in parallel, which can be respectively arranged on both sides of the arc groove 303, or on the same side as shown in the figure. Two conductive wheels are provided on the motor seat, which are respectively connected to the two wiring ports of the drive motor. The two conductive wheels contact and cooperate with the two conductive rails accordingly. The two conductive wheels can be installed on the same side of the motor seat, or can be installed on both sides of the motor seat as shown in the figure. The conductive rail 10 is connected to a power supply for supplying power to the drive motor through the conductive wheel 11. When the drive motor needs to be reversed, the relevant circuits can be controlled by a controller to switch the polarity of the two conductive rails 10.

[0035] The driving motor can be powered by a battery as a power source. When the support component 1 adopts the method of holding the support rod 102, the battery can be set at the handheld end to balance the weight of the two ends of the support rod 102, so as to facilitate stable holding. After the cleaning component 2 is sent to the position of the insulator by the support component 1, after the cleaning head 401 of the cleaning mechanism 4 contacts the insulator, the driving motor, on the one hand, drives the cleaning mechanism 4 to revolve around the insulator along the arc guide mechanism 3 through the cooperation of the driving gear and the arc rack, and on the other hand, drives the cleaning head 401 to rotate outward along the direction of revolution, removes surface impurities from the insulator, instead of accumulating at the root of the skirt of the insulator, which is better than the effect of cleaning by surface friction alone. Because when it rotates and revolves around the periphery of the insulator, the two superimposed motions produce an outward parabolic curve, which not only has a good cleaning effect, but also leaves no cleaning dead corners. In order to improve efficiency, two cleaning components 2 are set on both sides of the insulator so that the two cleaning components 2 are closed around the insulator. The center line of the cleaning heads 401 of the two cleaning components 2 is always kept at the maximum, and the cleaning mechanisms 4 of the two cleaning components 2 are controlled to always revolve in the same direction to prevent the bristles from getting tangled. Since the cleaning heads rotate clockwise and counterclockwise around the insulator, their rotation is not constant and can rotate forward and backward. In this way, there is no need to worry about the problem that part of the brush head is always compressed and deformed on one side and cannot be restored.

[0036] The above description of the specific implementation mode is only used to help understand the technical concept and core idea of ​​the present invention. Although the technical solution is described and illustrated using a specific preferred embodiment, it should not be understood as a limitation of the present invention itself. Those skilled in the art may make various changes in form and details without departing from the technical concept of the present invention. These easily conceived changes or substitutions should all be included in the protection scope of the present invention.
