Description

Technical Field

[0001] This invention belongs to the field of line acceptance technology, and in particular relates to a cleaning device for power distribution line acceptance. Background Technology

[0002] After the construction of power distribution lines, dust, debris and other pollutants are easily attached to the surface. If they are not cleaned during acceptance, they will reduce the insulation performance of insulators, obscure component defects, interfere with the accuracy of insulation resistance testing, accelerate the corrosion of hardware, and fail to meet the commissioning acceptance standards. Therefore, cleaning is required during the acceptance phase.

[0003] In the acceptance and cleaning of high-altitude power distribution lines, although traditional high-pressure flushing technology is widely used, it has significant technical shortcomings due to the limitations of the working environment and technical characteristics. On the one hand, because the lines are located at high altitudes, the spray range of the flushing medium is easily limited by gravity and distance, and can only effectively act on the bottom area of ​​the line. It is difficult to achieve full circumferential cleaning coverage of components such as conductors and insulators, and cannot meet the comprehensive requirements for line cleanliness during the acceptance stage. On the other hand, this technology is highly dependent on the working terrain. In complex terrain areas such as mountainous areas, river crossings, and hills, the entry and installation of ground flushing equipment is difficult, and the feasibility and efficiency of the operation are greatly reduced.

[0004] To address these issues, high-altitude spraying technology using drones has emerged as a crucial technological direction for high-altitude power line inspection and cleaning. However, during operation, it is essential to precisely control the drone's spray nozzles to move along the power line to ensure effective cleaning. Power lines, due to their weight and sag effect, naturally sag rather than being perfectly straight. This places extremely high demands on the drone's flight control precision, path planning capabilities, and the professional skills of the operators, significantly increasing the difficulty of operation and potentially leading to discontinuous or incomplete cleaning, thus affecting the overall quality and efficiency of the inspection work. Summary of the Invention

The movable ends of the two connecting belts slide through the bottom of the hollow winding plate. An upper encoder is fixed to the end of the hollow winding plate, and the rotating end of the upper encoder is fixedly connected to the rotating shaft. The winding motor, the electromagnetic clutch, and the upper encoder are all electrically connected to the cleaning controller. A tension monitoring component is installed on the connecting belt, and the connecting belt is connected to the top of the drive mechanism through the tension monitoring component.

[0013] Preferably, the driving mechanism includes a slotted plate, and a lead screw drive assembly is installed inside the slotted plate. The lead screw drive assembly drives two semi-circular clamping plates on the same side to move. A lower encoder is fixed to the side wall of the slotted plate, and the rotating end of the lower encoder is connected to the rotating end of the lead screw drive assembly. The lead screw drive assembly and the lower encoder are electrically connected to the cleaning controller. A pushing assembly is installed on both slotted plates.

[0014] Preferably, the tension monitoring component includes a tension sensor fixed to the top of the slot plate, and a connecting strip is fixed to the top of the tension sensor. The movable end of the connecting strip is fixedly connected to the top of the connecting strip, and the tension sensor is electrically connected to the cleaning controller.

[0015] Preferably, the pushing assembly includes connecting rings fixed to the sidewalls of two opposing slot plates, and an electric push rod is fixed between the two connecting rings. The electric push rod is electrically connected to the cleaning controller.

[0016] Preferably, the liquid supply flushing unit includes a high-pressure pulse cleaning pump fixed to the bottom of the hollow substrate. A fixing block is fixedly sleeved at the water outlet of the high-pressure pulse cleaning pump. A docking hollow block communicating with the water outlet of the high-pressure pulse cleaning pump is provided below the fixing block, and a cleaning controller is fixed at the bottom of the docking hollow block.

[0018] Compared with existing technologies, the advantages of a cleaning device for power distribution line acceptance are:

The cleaning method can be adjusted according to the curvature of the power distribution lines to facilitate wrapping and washing of the lines. In addition, the distance between the drone and the cleaning end can be flexibly adjusted to reduce the difficulty of drone operation.

[0020] 2. The tension monitoring component can automatically adjust the distance between the drone and the cleaning end based on changes in tension. The push component can make the cleaning end move automatically along the line without relying on the traction force of the drone, which effectively improves the stability between the cleaning end and the line and helps to improve the cleaning effect.

[0021] 3. By setting up a docking locking component, the lock between the drone and the cleaning end can be automatically released when the drone falls out of control, thus preventing the drone from affecting the power distribution line and reducing losses when it falls accidentally.

Detailed Implementation

[0031] 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 present invention, and not all embodiments.

[0032] like Figures 1-8As shown, a cleaning device for power distribution line acceptance includes a drone 1 and a water tank 2 installed inside the drone 1. A cleaning controller 3 is provided below the water tank 2. The device also includes a hollow base plate 4, which is located below the water tank 2. A suspension assembly 5 connected to the hollow base plate 4 is installed on the water tank 2. The suspension assembly 5 includes an upper stainless steel hose 51 fixedly connected to the bottom of the water tank 2, and a lower stainless steel hose 52 fixedly connected to the top of the hollow base plate 4. The upper stainless steel hose 51 and the lower stainless steel hose 52 are connected to each other through a pipe connector 53. Suspension steel ropes 54 connected to the bottom of the pipe connector 53 are fixed at the four corners of the top of the hollow base plate 4.

[0033] Two winding adjustment units 6 are installed at the bottom of the hollow substrate 4. A drive mechanism 7 is installed at the movable end of each winding adjustment unit 6. Each winding adjustment unit 6 includes a hollow winding plate 61 fixed to the bottom of the hollow substrate 4. A winding motor 62 is fixed to the side wall of the hollow winding plate 61. An electromagnetic clutch 63 is installed at the output end of the winding motor 62, and a rotating shaft 64 is fixedly connected to the rotating end of the electromagnetic clutch 63. Two winding wheels 65 are fixedly sleeved on the rotating shaft 64, and both winding wheels 65 are wound with connecting belts 66. The movable ends of the two connecting belts 66 slide through the bottom of the hollow winding plate 61. An upper encoder 67 is fixed to the end of 61, and the rotating end of the upper encoder 67 is fixedly connected to the rotating shaft 64. The winding motor 62, the electromagnetic clutch 63, and the upper encoder 67 are all electrically connected to the cleaning controller 3. The connecting belt 66 is equipped with a tension monitoring component 10, and the connecting belt 66 is connected to the top of the drive mechanism 7 through the tension monitoring component 10. When the electromagnetic clutch 63 is energized, its moving plate engages with the stationary plate to ensure the effective transmission of the rotational driving force of the winding motor 62. The winding motor 62 is a self-locking motor. When the electromagnetic clutch 63 is de-energized, the moving plate separates from the stationary plate, and the rotating shaft 64 can rotate freely.

[0034] Both sets of semicircular clamping plates 8 are located below the winding adjustment unit 6. The drive mechanism 7 drives one set of semicircular clamping plates 8 on the same side to move. The drive mechanism 7 includes a slot plate 71. A lead screw drive assembly 72 is installed inside the slot plate 71. The lead screw drive assembly 72 drives the two sets of semicircular clamping plates 8 on the same side to move. A lower encoder 73 is fixed to the side wall of the slot plate 71, and the rotating end of the lower encoder 73 is connected to the rotating end of the lead screw drive assembly 72. The lead screw drive assembly 72 and the lower encoder 73 are electrically connected to the cleaning controller 3. The two slot plates 71 are jointly equipped with a push assembly 11. The push assembly 11 includes a connecting ring 111 fixed to the side wall of the two slot plates 71 facing each other. An electric push rod 112 is fixed between the two connecting rings 111. The electric push rod 112 is electrically connected to the cleaning controller 3.

[0035] The tension monitoring component 10 includes a tension sensor 101 fixed to the top of the trough plate 71, and a connecting strip 102 fixed to the top of the tension sensor 101. The movable end of the connecting strip 66 is fixedly connected to the top of the connecting strip 102. The tension sensor 101 is electrically connected to the cleaning controller 3. The threshold of the tension sensor 101 can be preset according to parameters such as the structural weight of the trough plate 71 and the other components located at the movable end of the connecting strip 66.

[0036] The liquid supply rinsing unit 9 is installed at the bottom of the hollow substrate 4, and sprays the cleaning agent in the water tank 2. The liquid supply rinsing unit 9 includes a high-pressure pulse cleaning pump 91 fixed to the bottom of the hollow substrate 4. A fixing block 92 is fixedly sleeved on the water outlet end of the high-pressure pulse cleaning pump 91. A docking hollow block 93 connected to the water outlet end of the high-pressure pulse cleaning pump 91 is provided below the fixing block 92. The cleaning controller 3 is fixed to the bottom of the docking hollow block 93. Four connecting stainless steel hoses 94 are fixed to the side wall of the docking hollow block 93. A semi-circular hollow plate 95 is fixed to the side wall of the semi-circular clamp 8 near the docking hollow block 93. The semi-circular hollow plate 95 is connected to the stainless steel flexible hose 94. Several water spray holes 96 are opened on the inner side wall. The top of the docking hollow block 93 is fixed with a lower conductive contact 97. The bottom of the fixing block 92 is opened with a groove that matches the lower conductive contact 97. The upper conductive contact 98 is fixed inside the groove. The docking hollow block 93 is equipped with a docking locking assembly 12 connected to the fixing block 92. Through the lower conductive contact 97 and the upper conductive contact 98, the drone 1 battery can power the cleaning controller 3 during normal operation. When the drone 1 crashes out of control, the backup battery of the cleaning controller 3 provides temporary power to the lead screw drive assembly 72 and other components.

[0037] The docking locking assembly 12 includes support blocks 121 fixed on both sides of the top of the docking hollow block 93. An elastic telescopic rod 122 is fixedly inserted into the side wall of the support block 121, and a locking block 123 is fixed to the movable end of the elastic telescopic rod 122. An inclined bevel is opened at the lower end of the side wall of the locking block 123. A locking groove 124 matching the locking block 123 is opened on the side wall of the fixed block 92. The elastic telescopic rod 122 includes components such as a fixed cylinder, a telescopic rod, and an elastic element, so that the fixed block 92 can be smoothly separated from the docking hollow block 93 when the UAV 1 is out of control.

[0038] The operating principle of this invention is explained as follows: The fixing block 92 is aligned with the docking hollow block 93, allowing the locking block 123 to be inserted into the corresponding locking groove 124. At this time, the water outlet of the high-pressure pulse cleaning pump 91 is connected to the docking hollow block 93, and the upper conductive contact 98 is connected to the lower conductive contact 97. Then, the upper stainless steel hose 51 and the lower stainless steel hose 52 are connected and fixed using a pipe connector. Simultaneously, an appropriate amount of cleaning agent is poured into the water tank 2. The entire device is then inspected. After all preparations are complete, the flight parameters of the drone 1 are pre-set according to the path and altitude of the power distribution line. Then, the drone 1 is controlled by the drone's remote controller to take off and fly above the power distribution line to be inspected, positioned at the starting point of the power distribution line inspection. The drone 1 moves the semi-circular clamp 8 close to the power line. Based on the curvature of the line at the starting end, the remote control operates the winding motor 62 on the same side as the lowest point of the line, causing the connecting tape 66 on the same side to be released. At this time, the semi-circular clamps 8 on both sides begin to tilt. After the tilt is roughly matched with the line, the winding motor 62 stops working. Then, the control screw drive assembly 72 is started. The screw drive assembly 72 drives the two semi-circular clamps 8 on the same side to move towards each other. The screw drive assembly 72 detects the number of rotations of the screw through the lower encoder 73. After rotating to the set number of rotations, the screw drive assembly 72 stops working. At this time, the semi-circular clamp 8 will clamp the power line. After pressing the cleaning button on the remote control, the cleaning work can be started.

[0039] After the cleaning operation is started, the drone 1 will fly according to the preset flight parameters, and the cleaning controller 3 will control the high-pressure pulse cleaning pump 91 to work. The high-pressure pulse cleaning pump 91 will extract the cleaning agent inside the hollow substrate 4 and deliver it to the interior of the semi-circular hollow plate 95 in a pulse manner through the docking hollow block 93 and the connecting stainless steel hose 94. It will then spray the cleaning agent onto the surface of the power distribution line through various water spray holes 96, thereby washing and cleaning the dirt on the surface of the power distribution line. The cleaning agent inside the water tank 2 will be replenished into the interior of the hollow substrate 4 through the upper stainless steel hose 51 and the lower stainless steel hose 52.

[0040] After the cleaning operation is started, the cleaning controller 3 controls the lead screw drive assembly 72 on the lower side of the line to rotate for 2 seconds, so that the semi-circular clamp 8 on that side is detached from the line. Then, the electric push rod 112 is activated to release the connecting belt 66 on that side. Since the semi-circular clamp 8 on the other side is still clamped and fixed to the line, the semi-circular clamp 8 that has detached from the line will move along the line when the electric push rod 112 is working. After the electric push rod 112 finishes a single stroke, the cleaning controller 3 controls the lead screw drive assembly 72 on that side to work again, so that the semi-circular clamp 8 clamps and fixes the line again. At the same time, it controls the semi-circular clamp 8 on the other side to detach from the line. Similarly, the semi-circular clamp 8 on the other side will also move along the line. Through the alternating work of the lead screw drive assemblies 72 on both sides, the semi-circular clamp 8 can be moved along the line, so that the line can be fully covered and fully wrapped for cleaning. Moreover, the structure of the cleaning end does not require the drone 1 to be pulled and moved, so the operation difficulty of the drone 1 can be reduced.

[0041] Secondly, when the semicircular clamp 8 moves, the groove plate 71 moves synchronously. At this time, the groove plate 71 will pull the connecting belt 66 through the tension sensor 101. The tension sensor 101 will increase, and the electrical signal strength fed back to the cleaning controller 3 by the tension sensor 101 will increase synchronously. The cleaning controller 3 will then control the winding motor 62 to release the connecting belt 66. At the same time, when the tension sensor 101 decreases, the cleaning controller 3 will wind up the connecting belt 66 to keep the tension sensor 101 within the tension threshold range. Similarly, during the flight of the drone 1, if the altitude of the drone 1 changes, the tension sensor 101 will also detect the change in tension, and the cleaning controller 3 will control the winding motor 62 to perform corresponding actions to prevent the change in altitude of the drone 1 from dragging the power line through the semicircular clamp 8, further reducing the difficulty of precise control of the drone 1. The drone 1 only needs to fly according to the preset flight parameters.

[0042] If the drone 1 falls out of control during use, due to the weight of the drone 1 plus the water tank 2, it will exert a large pulling force on the hollow substrate 4 when it is below the height of the hollow substrate 4. Since the semi-circular clamp 8 is fixed to the line, the pulling force on the tension sensor 101 will increase rapidly. At this time, an alarm message will pop up on the remote control. The operator can press the release button on the remote control, and the cleaning controller 3 will control the electromagnetic clutch 63 to de-energize. At this time, the rotation of the shaft 64 is no longer restricted by the winding motor 62 and can rotate freely, allowing the connecting belt 66 to be released freely. Therefore, the drone 1 will not cause excessive pulling on the line when it falls, avoiding damage to the line. Secondly, when the tension sensor 101 detects that the pulling force has reached its maximum value, the cleaning controller 3 will automatically control the electromagnetic clutch 63 to de-energize, without requiring manual pressing of the release button, ensuring that the connecting belt 66 is released smoothly. In addition, after the electromagnetic clutch 63 is de-energized, due to the pulling force exerted on the hollow substrate 4 by the falling drone 1, the hollow substrate 4 will be cleaned by high-voltage pulses. The cleaning pump 91 and the fixing block 92 move synchronously. At this time, the groove of the fixing block 92 will squeeze the inclined bevel of the locking block 123. Due to the excessive pulling force of the falling drone 1, the squeezing force will overcome the elastic support force of the elastic telescopic rod 122, thereby causing the locking block 123 to disengage from the groove. At this time, the fixing block 92 and the docking hollow block 93 can be smoothly separated. During normal operation, the docking of the fixing block 92 and the docking hollow block 93 can ensure that the cleaning agent can smoothly enter the interior of the docking hollow block 93 and can pass through the upper conductive contact. 98 and the lower conductive contact 97 are connected, and the battery of the drone 1 supplies power to the electric push rod 112, the lead screw drive assembly 72, etc. When the drone 1 falls and the tension detected by the tension sensor 101 exceeds the threshold, the electric push rod 112, the lead screw drive assembly 72, etc. are powered by the backup battery inside the cleaning controller 3. After the drone 1 falls, the lead screw drive assembly 72 can be controlled by the remote control to drive the semi-circular clamp 8 to disengage from the circuit, so that the semi-circular clamp 8 can be disengaged from the circuit after the drone 1 falls out of control.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
