Description

Technical Field

[0001] The invention relates to a foreign matter cleaning device, in particular to a foreign matter cleaning device for a distribution network line applied in the technical field of distribution network maintenance. Background Art

[0002] A distribution network refers to an electric power grid that receives electrical energy from a transmission network or a regional power plant and distributes it locally or step by step according to voltage to various types of users through distribution facilities. The lines of the distribution network are erected at high altitudes. There are many kinds of foreign objects on the lines of the distribution network, including kites, plastic bags, and other textile fragments. The presence of foreign objects will affect the safe operation of the lines and easily cause safety accidents such as fires.

[0003] The specification of Chinese invention patent CN202111445047.5 discloses "A robot for cleaning foreign objects from agricultural distribution network lines". Through the robot's live operating machine, the target foreign object capture device and the target foreign object ranging device, the target foreign object can be identified and located, which improves the working efficiency and quality, helps to reduce the labor intensity and danger of grassroots employees, and improves the degree of automation of agricultural distribution network operations.

[0004] Most of the existing distribution network lines are cleaned manually, and the removal of foreign objects is troublesome, and high-altitude operations carry potential safety hazards. Therefore, the market is beginning to use unmanned remote equipment to clean high-altitude lines. The above invention uses an unmanned robot to use a cleaning saw disk to cut and clean foreign objects. Since foreign objects are suspended on the surface of the line and are in close contact with the line, it is easy to cause incomplete cleaning of foreign objects. Direct cutting of foreign objects is easy to cause damage to the line, affecting the cleaning effect of foreign objects. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that since foreign objects are suspended on the surface of the circuit and are in close contact with the circuit, it is easy to cause incomplete cleaning of the foreign objects, and directly cutting the foreign objects is easy to cause damage to the circuit, affecting the cleaning effect of the foreign objects.

[0006] In order to solve the above problems, the present invention provides a foreign body cleaning device for distribution network lines, comprising an unmanned aerial vehicle body and a line, wherein a cleaning frame is fixedly connected to the bottom of the unmanned aerial vehicle body, the cleaning frame is placed on the top of the line, both ends of the cleaning frame are fixedly connected to fixed pad knives, the fixed pad knives correspond to the axis of the line, and both ends of the unmanned aerial vehicle body are rotatably connected to rotating scissors, the rotating scissors correspond to the fixed pad knives;

[0007] The left and right ends of the middle part of the cleaning frame are movably connected with telescopic frame clamps, the middle part of the telescopic frame clamp is rotatably connected with the line running wheel, both ends of the telescopic frame clamp are rotatably connected with grabbing wheels, the grabbing wheels correspond to the fixed pad knife, the end of the grabbing wheel close to the fixed pad knife is fixedly connected with a claw rod, the middle part of the grabbing wheel is fixedly connected with a transmission wheel, a driving belt is rotatably connected between the two transmission wheels, and the bottom of the line running wheel is fixedly connected with a transmission gear, which meshes with the driving belt.

[0008] In the above-mentioned distribution network line foreign object cleaning device, an unmanned aerial vehicle is landed on the line and used to walk for cleaning. During the walking process, the grabbing wheels lift the suspended foreign objects, so that the top of the foreign object is separated from the line, making it easier for the top of the foreign object to rise to the fixed pad knife, effectively improving the cutting effect of the foreign objects, thereby effectively improving the thorough cleaning effect of the foreign objects on the line.

[0009] As a further improvement of the present application, the blade end of the fixed pad knife is arranged in an inclined surface, and the bottom of the blade end of the fixed pad knife is fixedly connected with a guide rib, the guide rib corresponds to the fixed pad knife shaft, and the guide rib is made of rubber material. The guide rib is inserted between the top of the foreign object and the line, which facilitates the foreign object to rise along the inclined blade of the fixed pad knife, effectively improving the shearing effect of the foreign object.

[0010] As a further improvement of the present application, a stopper is fixedly connected to the root of the fixed pad knife, a shear trigger module is fixedly connected to the middle part of the stopper, and the output end of the shear trigger module is connected to the driving end of the rotating scissors. The stopper is used to prevent foreign matter from rising excessively to prevent the foreign matter from being stuck at the root of the fixed pad knife, and the shear trigger module is used to detect the accumulation of foreign matter on the fixed pad knife, so as to facilitate the shearing of the foreign matter by the rotating scissors and the fixed pad knife.

[0011] As a further improvement of the present application, the shear trigger module is composed of a pressure pad and a pressure sensor. The pressure sensor is fixedly installed on the back of the pressure pad. The pressure pad is hinged to the block. The accumulation of foreign matter causes the pressure pad to rotate, compressing the pressure sensor to trigger the shear trigger module.

[0012] As another improvement of the present application, the claw rod is fixedly connected to the outside with side claws, and both the claw rod and the side claws are made of elastic rubber material. The side claws effectively improve the claw rod's ability to grasp foreign objects, and the claw rod and the side claws have excellent elastic effects, which facilitates the claw rod and the side claws to bend and detach from foreign objects.

[0013] As another improvement supplement of the present application, the left and right ends of the bottom of the cleaning frame are rotatably connected to a rotating shaft, and both ends of the rotating shaft are fixedly connected to comb teeth. The comb teeth and claw rods correspond to each other in an alternating manner. The claw rods rotate through the comb teeth to leave foreign matter on the upper surface of the comb teeth.

[0014] As another improved supplement of the present application, an attachment hook is fixedly connected to the upper surface of one of the two comb teeth, and the comb teeth with the attachment hook are distributed at the left and right ends of the cleaning frame. The attachment hook is made of stainless steel material, and the comb teeth are used to hook the cut foreign matter, effectively preventing the foreign matter from falling, making it convenient for the foreign matter to be recovered together with the device.

[0015] As another improvement of the present application, grooves are provided at both the front and rear ends of the top of the cleaning frame, a wire hole is provided at the top of the groove, a connecting wire is inserted inside the wire hole, the two ends of the connecting wire are respectively fixedly connected to the two comb teeth at the same end, the middle part of the connecting wire is in contact with the line, and the two comb teeth are restricted by the connecting wire. When the cleaning frame is placed on the line, the connecting wire is lifted up by the line, and the comb teeth are pulled to rotate to the claw rod position.

[0016] As another improvement supplement of the present application, a protective tube is fixedly connected to the inside of the groove, both ends of the protective tube correspond to the wire holes, the protective tube is made of wear-resistant textile material, and the connecting wire is made of tensile fiber material. The protective tube is used to wrap the connecting wire and guide the connecting wire to be stored in the groove, thereby effectively reducing the friction effect of the connecting wire on the line.

[0017] To summarize, the present invention carries the cleaning frame to the top of the line through the unmanned aerial vehicle, and retracts the line wheels to clamp the line through the telescopic frame clamp, so that the cleaning frame can move on the line, effectively avoiding the high risk and difficulty of manual climbing of the line, thereby effectively improving the safety of work, and the grabbing wheels rotate synchronously, and the claw rod is used to pick up the suspended foreign objects upward, and the claw rod that can bend elastically deformed effectively avoids any damage to the line during the picking process. After the foreign objects are picked, they are separated from the line to produce a gap into which the fixed pad knife can be inserted, thereby facilitating the rotating scissors and the fixed pad knife to cut off the foreign objects, and the subsequent rotating claw rod continues to provide downward pulling to the cut foreign objects, so that the cut foreign objects are convenient to be separated from the line, effectively improving the thorough cleaning effect of foreign objects on the line, and reducing the occurrence of line failures and safety accidents caused by foreign objects.

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-2The figure shows a device for cleaning foreign matter in a power distribution network line, comprising an unmanned aerial vehicle 1 and a line 101, wherein a cleaning frame 102 is fixedly connected to the bottom of the unmanned aerial vehicle 1, and the cleaning frame 102 is placed on the top of the line 101, and both ends of the cleaning frame 102 are fixedly connected to fixed pad knives 103, and the fixed pad knives 103 correspond to the axis of the line 101, and both ends of the unmanned aerial vehicle 1 are rotatably connected to rotating scissors 104, and the rotating scissors 104 correspond to the fixed pad knives 103, and the blade end of the fixed pad knives 103 is arranged in an inclined surface, and a guide rib 105 is fixedly connected to the bottom of the blade end of the fixed pad knives 103, and the guide rib 105 corresponds to the fixed pad knives 103 axially, and the guide rib 105 is made of rubber material, and the guide rib 105 is inserted between the top of the foreign matter and the line 101, so that the foreign matter can rise along the inclined blade of the fixed pad knife 103, thereby effectively improving the shearing effect of the foreign matter;

[0035] Figure 2-3 It is shown that a stopper 106 is fixedly connected to the root of the fixed pad knife 103, a shearing trigger module 3 is fixedly connected to the middle of the stopper 106, the output end of the shearing trigger module 3 is connected to the driving end of the rotating scissors 104, the stopper 106 is used to prevent foreign matter from rising excessively, so as to prevent the foreign matter from being stuck at the root of the fixed pad knife 103, and the shearing trigger module 3 is used to detect the accumulation of foreign matter on the fixed pad knife 103, so as to facilitate the shearing of foreign matter by the rotating scissors 104 and the fixed pad knife 103, the shearing trigger module 3 is composed of a pressure pad 301 and a pressure sensor 302, the pressure sensor 302 is fixedly installed on the back of the pressure pad 301, the pressure pad 301 is hinged to the stopper 106, the accumulation of foreign matter causes the pressure pad 301 to rotate, and the pressure sensor 302 is compressed to trigger the shearing trigger module 3;

[0036] When the fixed pad knife 103 is inserted between the foreign object and the line 101, the foreign object gradually rises to the root of the fixed pad knife 103. When the foreign object rises along the blade of the fixed pad knife 103, the foreign object can also be cut off and blocked by the block 106. The block 106 is provided to prevent the foreign object from being stuck at the root of the fixed pad knife 103. Subsequently, as the cleaning frame 102 continues to move, the foreign object applies pressure to the shear trigger module 3, causing the pressure pad 301 to rotate, and the compression pressure sensor 302 triggers the shear trigger module 3, so that the rotating scissors 104 and the fixed pad knife 103 are closed to cut off the foreign object, effectively realizing the complete cutting off of the foreign object, thereby effectively improving the thorough cleaning effect of the foreign object.

[0037] Figure 4-7As shown, the left and right ends of the middle of the cleaning frame 102 are movably connected with a telescopic frame clamp 2, the middle of the telescopic frame clamp 2 is rotatably connected with a line running wheel 201, and both ends of the telescopic frame clamp 2 are rotatably connected with a grab wheel 202, the grab wheel 202 corresponds to the fixed pad knife 103, and the end of the grab wheel 202 close to the fixed pad knife 103 is fixedly connected with a claw rod 203, and the middle of the grab wheel 202 is fixedly connected with a transmission wheel 204, and a driving wheel 204 is rotatably connected between the two transmission wheels 204. The bottom of the belt 205 and the line wheel 201 is fixedly connected with a transmission gear 206, which meshes with the driving belt 205. The outside of the claw rod 203 is fixedly connected with a side claw 207, and the claw rod 203 and the side claw 207 are both made of elastic rubber material. The side claw 207 effectively improves the ability of the claw rod 203 to grasp foreign objects, and the claw rod 203 and the side claw 207 have excellent elasticity, which facilitates the claw rod 203 and the side claw 207 to bend and detach from foreign objects;

[0038] When the line wheel 201 drives the cleaning frame 102 to move towards the foreign matter, the transmission gear 206 at the bottom of the line wheel 201 synchronously drives the transmission wheel 204 through the drive belt 205, so that the grabbing wheel 202 rotates together, so that the claw rod 203 is used to pick up the suspended foreign matter, so that the top of the foreign matter is separated from the line 101 to create a gap for the fixed pad knife 103 to extend into, so that the foreign matter can be accurately raised to the blade of the fixed pad knife 103, so that the rotating scissors 104 and the fixed pad knife 103 can cut off the foreign matter, effectively improving the thorough cleaning effect of the foreign matter on the line 101, and the rotating claw rod 203 continues to provide downward pulling on the cut foreign matter, so that the cut foreign matter can be separated from the line 101, further effectively improving the thorough cleaning effect of the foreign matter.

[0039] When cleaning foreign objects in the distribution network, the staff operates the unmanned aerial vehicle 1 to fly over the line 101 where the foreign objects exist, and slowly lowers the cleaning frame 102 onto the line 101, then the telescopic frame clamp 2 retracts the line running wheel 201 to clamp the line 101, and stops the flight of the unmanned aerial vehicle 1, and then uses the line running wheel 201 to drive the cleaning frame 102 to move toward the foreign objects on the line 101, driving the fixed pad knife 103 to extend between the foreign objects and the line 101, and then closes the rotating scissors 104 and the fixed pad knife 103 to cut off the foreign objects, thereby achieving the removal and cleaning of foreign objects on the line 101, and effectively improving the effect of thorough cleaning of foreign objects.

[0040] The second implementation method:

[0041] Compared with the first embodiment, this embodiment mainly adds a rotating shaft 4 and a comb tooth piece 401. The specific newly added structure is as follows, and the remaining structure is consistent with the first embodiment.

[0042] Figure 8-10As shown, the left and right ends of the bottom of the cleaning frame 102 are rotatably connected with a rotating shaft 4, and both ends of the rotating shaft 4 are fixedly connected with comb teeth 401, the comb teeth 401 and the claw rods 203 correspond to each other in an alternating manner, and the claw rods 203 rotate through the comb teeth 401 to leave foreign matter on the upper surface of the comb teeth 401, and the upper surface of one of the two comb teeth 401 is fixedly connected with an attachment hook 402, and the comb teeth 401 with the attachment hook 402 are distributed at the left and right ends of the cleaning frame 102, and the attachment hook 402 is made of stainless steel material, and the comb teeth 401 is used to hook the cut foreign matter, which effectively prevents the foreign matter from falling, and facilitates the foreign matter to be recovered together with the device;

[0043] When the claw rod 203 continues to provide downward pulling on the cut foreign matter, the claw rod 203 passes through the comb teeth 401, and the foreign matter is retained on the comb teeth 401, effectively preventing the foreign matter from continuing to move with the claw rod 203, facilitating the subsequent use of the claw rod 203, and hooking the foreign matter by the attachment hook 402, effectively preventing the foreign matter from falling from the comb teeth 401, and the subsequent unmanned aerial vehicle 1 brings the unmanned aerial vehicle 1 back to the ground, facilitating the recovery of the foreign matter along with the device, and facilitating the harmless disposal of the foreign matter.

[0044] Figure 10-12 As shown, grooves 5 are provided at both the front and rear ends of the top of the cleaning frame 102, and a wire hole 501 is provided at the top of the groove 5. A connecting wire 502 is inserted into the wire hole 501. The two ends of the connecting wire 502 are respectively fixedly connected to the two comb teeth 401 at the same end. The middle part of the connecting wire 502 contacts the line 101. The two comb teeth 401 are restricted by the connecting wire 502. When the cleaning frame 102 is placed on the line 101, the connecting wire 502 is lifted by the line 101, and the comb teeth 401 are pulled to rotate to the position of the claw rod 203. A protective tube 503 is fixedly connected to the inside of the groove 5. Both ends of the protective tube 503 correspond to the wire hole 501. The protective tube 503 is made of wear-resistant textile material, and the connecting wire 502 is made of tensile fiber material. The protective tube 503 is used to wrap the connecting wire 502, guide the connecting wire 502 to be stored in the groove 5, and effectively reduce the friction effect of the connecting wire 502 on the line 101.

[0045] When the unmanned aerial vehicle 1 slowly lowers the cleaning frame 102 onto the line 101, the cleaning frame 102 is hung on the line 101, and the gravity of the cleaning frame 102 is used to tighten the connecting wire 502 of the line 101, so that the connecting wire 502 pulls the comb teeth 401, and the comb teeth 401 rotates to the position of the claw rod 203, which is convenient for the interlaced operation of the comb teeth 401 and the claw rod 203. When the unmanned aerial vehicle 1 subsequently carries the cleaning frame 102 away from the line 101, the connecting wire 502 is relaxed again, and the comb teeth 401 droops again due to gravity, which is convenient for the cleaning frame 102 to be separated from the line 101.

[0046] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
