Description

Technical Field

[0001] The invention relates to the technical field of circuit maintenance, and in particular to a cleaning device for circuit maintenance. Background Art

[0002] Insulators are devices installed between conductors of different potentials or between conductors and ground potential components. They can withstand voltage and mechanical stress. Dirt on the surface of insulators can cause power outages. Therefore, it is necessary to clean the dirt on the surface of insulators regularly. The existing cleaning method is generally live cleaning, which can quickly remove various static electricity, dust, oil, charged particles and other comprehensive pollutants, reduce the corrosion of the insulation layer, and protect the anti-pollution flash layer.

[0003] The existing live cleaning method mainly utilizes a water pump, a water pipe and a water gun, so that the live cleaning agent is sprayed out by the water gun to wash away the dirt on the surface of the shed, thereby realizing the cleaning function of the insulator. However, due to the limited position of the staff on the high-voltage line rack, the insulator can only be washed from one direction, resulting in the back of the insulator not being easily washed, so that the insulator cleaning is not thorough enough. In addition, since the structure of the shed of the suspension insulator is that the upper surface is in the shape of an arc, the bottom surface is flat and has a plurality of folds, it is not easy for the water gun to wash the dirt on the bottom surface of the suspension insulator and the inner side of the folds, which further reduces the cleaning quality of the insulator by the existing washing equipment. Therefore, a cleaning device for circuit maintenance is proposed to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, the position of the workers on the high-voltage line rack is limited and they can only flush the insulator from one direction, which makes it difficult to flush the back of the insulator, and the particularity of the shed structure of the suspension insulator makes it difficult for the existing flushing equipment to flush the bottom surface of the shed. A cleaning device for circuit maintenance is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The handheld assembly comprises cross-arranged handheld articulated cranks, which are articulated with each other. When the handheld articulated cranks are closed with each other, a clamping function for one end of the insulator is realized. A locking member for realizing a locking function is arranged on the handheld articulated cranks.

[0008] The driving assembly includes a driving screw shaft threadedly connected to the handheld articulated crank and a connecting sleeve slidably connected to the top of the driving screw shaft, an energy storage spring is rotatably arranged between the inner wall of the connecting sleeve and the top of the driving screw shaft, a lifting driving gear is fixedly connected to the top of the connecting sleeve, and an inner semi-conical gear ring is arranged at the top of the lifting driving gear;

[0009] The rotary lifting and flushing mechanism comprises an external rotating semi-toothed ring slidably arranged on the side wall of the inner semi-conical gear ring and a servo motor installed on the side wall of the external rotating semi-toothed ring, a support ring is fixedly connected to the motor housing surface of the servo motor, a storage sleeve is rotatably arranged on the inner side of the support ring, one end of the storage sleeve is fixedly connected to a rolling bevel gear meshing with the inner semi-conical gear ring, and the rolling of the rolling bevel gear is used to drive the rotary lifting and flushing mechanism to make a circular motion along the inner semi-conical gear ring, and at the same time, the lifting drive gear is driven to rotate through the external rotating semi-toothed ring, thereby driving the driving screw shaft to rotate, so that the driving screw shaft moves downward and stretches the energy storage spring to store energy, so as to prepare for the downward movement of the cleaning nozzle and the layer change;

[0010] A sliding opening is provided inside the rolling bevel gear, a cleaning nozzle is slidably arranged inside the sliding opening, and the cleaning nozzle extends between adjacent umbrella skirts to facilitate flushing the bottom surface of the umbrella skirts.

[0012] Preferably, a circumferential driven gear is fixedly connected to the surface of the storage sleeve, and a circumferential driving gear meshing with the circumferential driven gear is fixedly connected to the output end of the servo motor.

[0013] Preferably, the cleaning agent replenishing assembly includes a cleaning agent storage box, a micro pump is provided at the bottom end of the cleaning agent storage box, a cleaning agent butt joint is fixedly connected to the top end of the cleaning agent storage box, a sealing ring is fixedly connected to the inner wall of the cleaning agent butt joint, a leak-proof sealing plug is provided on the inner side of the sealing ring, the leak-proof sealing plug is connected to the sealing ring via a sealing spring, and a guide conical disc is provided on the surface of the cleaning agent butt joint.

[0016] Preferably, the magnetic attraction force between the force-applying magnetic ring and the fixed magnetic ring is greater than the tension of the sealing spring, so that the contact extension tube can push the leak-proof sealing plug downward to inject the cleaning agent into the interior of the cleaning agent storage box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This scheme is provided with a rotating lifting cleaning mechanism and a driving component. The driving component is used to drive the rolling bevel gear to rotate, so that the rolling bevel gear drives the cleaning nozzle to make a circular motion. At the same time, the micro pump delivers the cleaning agent to the inside of the storage sleeve. Under the action of water pressure, the cleaning nozzle moves out of the storage sleeve and extends between adjacent sheds.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Reference Figure 1A cleaning device for circuit maintenance includes a handheld component that is convenient for workers to take and a rotating lifting and flushing mechanism for cleaning sheds. The handheld component is connected to the rotating lifting and flushing mechanism through a driving component. The driving component controls the rotating lifting and flushing mechanism to rotate and move vertically along the insulator, so that the bottom wrinkles and arc surfaces of each shed on the insulator can be fully and thoroughly flushed to ensure the cleaning quality of the insulator;

[0033] The handheld assembly comprises cross-arranged handheld articulated cranks 1, which are articulated with each other; when the handheld articulated cranks 1 are closed with each other, a clamping function of one end of the insulator is realized, and a locking member 9 for realizing a locking function is arranged on the handheld articulated cranks 1;

[0034] It should be noted that the cross-arranged hand-held articulated cranks 1 are similar to scissors in structure;

[0035] It is worth noting that the locking member 9 is made of elastic plastic and has the elasticity to realize the snapping and removal functions of the handheld articulated crank 1; the handheld articulated crank 1 can realize the stable clamping function of one end of the insulator, helping the device to be stably installed on the insulator, thereby reducing the load on the staff holding the device.

[0036] Reference Figure 1 and Figure 8 The driving assembly includes a driving screw shaft 3 threadedly connected to the handheld articulated crank 1 and a connecting sleeve 32 slidably connected to the top of the driving screw shaft 3, an energy storage spring 31 is rotatably arranged between the inner wall of the connecting sleeve 32 and the top of the driving screw shaft 3, a lifting driving gear 41 is fixedly connected to the top of the connecting sleeve 32, and an inner semi-conical gear ring 5 is arranged at the top of the lifting driving gear 41;

[0037] It should be noted that: the servo motor drives the circumferential driving gear 72 to rotate, the circumferential driving gear 72 drives the circumferential driven gear 71 to rotate, the circumferential driven gear 71 drives the storage sleeve 7 to rotate, and the storage sleeve 7 drives the rolling bevel gear 73 to rotate, so that the rolling bevel gear 73 rolls on the semi-conical gear ring 5, which can drive the cleaning nozzle 6 to do a circular motion, and then the umbrella skirt can be fully cleaned;

[0038] It should be noted that: since the driving screw shaft 3 is threadedly connected to the handheld articulated crank 1, when the driving screw shaft 3 rotates, the driving screw shaft 3 will rotate downward and stretch the energy storage spring 31. When the cleaning nozzle 6 rotates one circle and the micro pump 81 is closed, the cleaning nozzle 6 is reset and separated from the umbrella skirt under the action of the reset spring 74. Under the downward pull of the energy storage spring 31, the semi-conical gear ring 5 and the external rotating semi-gear ring 4 drive the cleaning nozzle 6 to move downward and change layers, thereby cleaning each layer of the umbrella skirt layer by layer.

[0039] It is worth noting that: under the control of the controller, the micro pump 81 is turned off once every rotation, and then turned on again after a period of time.

[0040] Reference Figures 2 to 3 The rotary lifting and flushing mechanism includes an external rotating semi-toothed ring 4 slidingly arranged on the side wall of the inner semi-conical gear ring 5 and a servo motor installed on the side wall of the external rotating semi-toothed ring 4. A support ring is fixedly connected to the motor housing surface of the servo motor. A storage sleeve 7 is rotatably arranged on the inner side of the support ring. One end of the storage sleeve 7 is fixedly connected to a rolling bevel gear 73 meshing with the inner semi-conical gear ring 5. The rolling of the rolling bevel gear 73 drives the rotary lifting and flushing mechanism to make a circular motion along the inner semi-conical gear ring 5. At the same time, the lifting drive gear 41 is driven to rotate through the external rotating semi-toothed ring 4, thereby driving the driving screw shaft 3 to rotate, so that the driving screw shaft 3 moves downward and stretches the energy storage spring 31 to store energy, so as to prepare for the cleaning nozzle 6 to move down and change layers;

[0041] It should be noted that: the servo motor drives the circumferential driving gear 72 to rotate, which in turn drives the circumferential driven gear 71 to rotate, which in turn drives the storage sleeve 7 to rotate, the storage sleeve 7 drives the rolling bevel gear 73 and the cleaning nozzle 6 to rotate, the rolling bevel gear 73 drives the external rotating half-toothed ring 4 to rotate, and the external rotating half-toothed ring 4 drives the driving screw shaft 3 to rotate through the lifting drive gear 41.

[0042] It is worth noting that when the hand-held articulated crank 1 needs to be closed, the end surface of the external rotating half gear ring 4 needs to be flush with the end surface of the inner semi-conical gear ring 5, so as to facilitate closing the hand-held articulated crank 1 through 9;

[0043] Reference Figure 1 and Fig. 9 A sliding opening is provided inside the rolling bevel gear 73, and a cleaning nozzle 6 is slidably provided inside the sliding opening. The cleaning nozzle 6 extends between adjacent sheds to facilitate washing the bottom surface of the sheds.

[0044] It should be noted that: the cleaning nozzle 6 extends between adjacent sheds, and the cleaning nozzle 6 rotates while performing a circular motion, so that the cleaning agent can be sprayed in all directions and the spraying direction is directly facing the bottom surface and the arc surface of the shed, so that the dirt on the arc surface and the bottom surface folds of the shed can be washed well, thereby improving the cleaning quality and efficiency;

[0045] Reference Figure 1 and Fig. 9 One end of the cleaning nozzle 6 is fixedly connected to a piston block which is slidably connected to the inner wall of the storage sleeve 7. A water hole is provided at the center of the piston block. A reset spring 74 which helps the cleaning nozzle 6 to reset is fixedly connected between the piston block and the inner wall of the storage sleeve 7.

[0046] A circumferential driven gear 71 is fixedly connected to the surface of the storage sleeve 7 , and a circumferential driving gear 72 meshing with the circumferential driven gear 71 is fixedly connected to the output end of the servo motor.

[0047] It should be noted that: the servo motor drives the circumferential driving gear 72 to rotate, and then drives the circumferential driven gear 71 to rotate, the circumferential driven gear 71 drives the storage sleeve 7 to rotate, the storage sleeve 7 drives the cleaning nozzle 6 and the rolling bevel gear 73 to rotate, so that the external rotating half-toothed ring 4 rotates, and then drives the lifting drive gear 41 to rotate, and under the action of the driving screw shaft 3 and the energy storage spring 31, the rotating lifting flushing mechanism moves downward.

[0048] Reference Figure 3 to Figure 4 The other end of the storage sleeve 7 is rotatably provided with a cleaning agent replenishing assembly, which includes a cleaning agent storage box 8, a micro pump 81 is provided at the bottom end of the cleaning agent storage box 8, and a cleaning agent docking tube 82 is fixedly connected to the top of the cleaning agent storage box 8, and a sealing ring 84 is fixedly connected to the inner wall of the cleaning agent docking tube 82. A leak-proof sealing plug 86 is provided on the inner side of the sealing ring 84, and the leak-proof sealing plug 86 is connected to the sealing ring 84 through a sealing spring 85. A guiding conical disc 83 is provided on the surface of the cleaning agent docking tube 82, and a cleaning agent replenishing tube 2 connected to an external water pump is provided at the hinge of the hand-held articulated crank 1. A fixed magnetic ring 22 is fixedly connected to the pipe mouth of the cleaning agent replenishing tube 2, and a resisting extension tube 23 is provided on the inner side of the fixed magnetic ring 22.

[0049] It should be noted that: during the docking process between the cleaning agent replenishing tube 2 and the cleaning agent docking tube 82, the abutting extension tube 23 will first contact the guiding conical disc 83, so that the abutting extension tube 23 moves upward and retracts into the inner side of the cleaning agent replenishing tube 2. When the abutting extension tube 23 rotates to the top of the cleaning agent docking tube 82, under the action of the magnetic attraction between the force-applying magnetic attraction ring 21 and the fixed magnetic attraction ring 22, the end of the abutting extension tube 23 is inserted into the cleaning agent docking tube 82 and the leak-proof sealing plug 86 is pressed down, so that the cleaning agent can be injected into the cleaning agent storage box 8, thereby playing the cleaning agent replenishment function;

[0050] Reference Figure 4 At the same time, under the limiting effect of the internal volume of the cleaning agent storage box 8, the quantitative use function of the cleaning agent can be realized to avoid wasting the cleaning agent. The amount of cleaning agent stored in the cleaning agent storage box 8 is just the amount of cleaning agent sprayed after the cleaning nozzle 6 rotates one circle.

[0051] Reference Figure 4The end of the resisting extension tube 23 is spherical, and a spray hole is opened at the end of the resisting extension tube 23. The top of the resisting extension tube 23 is fixedly connected with a force magnetic ring 21 which is magnetically attracted to the fixed magnetic ring 22. The magnetic attraction force between the force magnetic ring 21 and the fixed magnetic ring 22 is greater than the pulling force of the sealing spring 85, so that the resisting extension tube 23 can push the leak-proof sealing plug 86 downward to inject the cleaning agent into the cleaning agent storage box 8.

[0052] It should be noted that the end of the abutting extension tube 23 is spherical, and when the abutting extension tube 23 continues to make a circular motion along with the cleaning agent replenishing tube 2, the abutting extension tube 23 can be separated from the cleaning agent docking tube 82 under the squeezing effect of the sealing ring 84.

[0053] When the present invention is used, the hand-held articulated crank 1 is closed to each other to achieve the clamping function of one end of the insulator. The device can be sleeved on the outside of the insulator, and the locking member 9 is clamped with the handle area of ​​the hand-held articulated crank 1, so that the hand-held articulated crank 1 can achieve the stable clamping function of one end of the insulator, helping the device to be stably installed on the insulator, thereby reducing the load on the staff holding the device;

[0054] Then, the servo motor is turned on, and the servo motor drives the circumferential driving gear 72 to rotate, and then drives the circumferential driven gear 71 to rotate, and the circumferential driven gear 71 drives the storage sleeve 7 to rotate, and the circumferential storage sleeve 7 drives the cleaning nozzle 6 and the rolling bevel gear 73 to rotate. Under the action of the inner semi-conical gear ring 5, the rolling bevel gear 73 drives the cleaning nozzle 6 and the external rotating semi-toothed ring 4 to rotate, and then drives the cleaning nozzle 6 to make a circular motion, and at the same time makes the cleaning nozzle 6 rotate. During this period, the micro pump 81 is turned on to transport the cleaning agent to the inner side of the storage sleeve 7. Under the water pressure of the cleaning agent, the cleaning nozzle 6 is gradually pushed out, so that the cleaning nozzle 6 gradually approaches the center of the umbrella skirt, and the bottom wrinkles and arc surface of the umbrella skirt can be fully and comprehensively washed, thereby improving the cleaning efficiency of the insulator and the cleaning quality;

[0055] When the external rotating half-toothed ring 4 rotates, it will drive the lifting drive gear 41 to rotate, and then drive the driving screw shaft 3 to rotate, so that the driving screw shaft 3 moves downward and stretches the energy storage spring 31 to store energy. When the cleaning nozzle 6 rotates one circle, the micro pump 81 is closed; when there is no water pressure, under the action of the reset spring 74, the cleaning nozzle 6 will be reset and separated from the arc surface of the shed. Under the elastic force of the energy storage spring 31, the semi-conical toothed ring 5 and the external rotating half-toothed ring 4 drive the cleaning nozzle 6 to move down and change layers, and then the micro pump 81 is turned on again to input the cleaning agent into the inner side of the storage sleeve 7. Under the action of water pressure, the cleaning nozzle 6 is pushed out again, and then the above cleaning operation is repeated until the cleaning operation of all sheds on the insulator is completed.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
