Description

Technical Field

[0001] The invention relates to the technical field of live working tools for power transmission lines, and in particular to a transmission line foreign matter removal device based on hot-melt technology. Background Art

[0002] In today's power industry, ensuring the safe and stable operation of transmission lines is a vital task. However, transmission lines have long been plagued by various foreign objects. Foreign objects such as kites, plastic bags, and branches often get entangled in transmission lines, which not only affects the beauty of the lines, but more seriously, they may cause line short circuits, tripping and other faults, posing a huge threat to the normal operation of the power system.

[0003] At present, the traditional method of removing foreign matter from power transmission lines is mainly to manually climb the tower to clean it, or use some simple tools to handle it. However, this background technology has many obvious disadvantages.

[0004] First of all, manual climbing of the tower to remove foreign objects is extremely unsafe. Operators are working at high altitudes and are at risk of falling at any time. Moreover, the transmission line itself carries high voltage electricity, and operators are also at risk of electric shock. In severe weather conditions, such as strong winds, thunderstorms, etc., manual cleaning work is more difficult to carry out, and safety hazards are further increased. Once a safety accident occurs, it will not only bring great pain to the operators and their families, but also cause serious damage to the image and reputation of the power company.

[0005] Secondly, the efficiency of manual cleaning of foreign objects is extremely low. Cleaning work requires a lot of time and manpower. For some foreign objects that are high and difficult to reach, cleaning is more difficult and takes longer. This not only affects the speed of power system recovery, but may also lead to prolonged power outages, causing huge economic losses to users and society.

[0006] Furthermore, there are great limitations in using simple tools for cleaning. These tools can only handle some smaller and lighter foreign objects, and are not effective for larger, heavier or tightly entangled foreign objects. Moreover, the operating range of simple tools is limited and cannot meet the needs of foreign object removal in complex situations. When faced with some special foreign objects, such as metal products, large billboards, etc., traditional cleaning methods are often helpless.

[0007] Finally, the cost of manual cleaning of foreign objects is high. Manual cleaning requires a lot of manpower and material resources, including the wages of operators and the investment in safety protection equipment. At the same time, due to the low cleaning efficiency, it may lead to prolonged power outages, which will also cause great economic losses to users and society. In addition, in order to ensure the safety of operators, a lot of training and safety management work is required, which also increases the cost burden of enterprises.

[0008] In summary, the traditional method of removing foreign matter from transmission lines can no longer meet the needs of modern power systems, and there is an urgent need for a safer, more efficient and intelligent foreign matter removal device to ensure the safe operation of transmission lines. Summary of the invention

[0009] The purpose of the present invention is to provide a power transmission line foreign body removal device based on hot melt technology, which can quickly and effectively remove foreign bodies on the power transmission line by hot melt technology of resistance wire. After the resistance wire is energized, it generates high temperature, which can efficiently process foreign bodies of different materials, greatly improving the efficiency of foreign body removal to solve the above problems.

[0010] To achieve the above object, the present invention provides the following technical solutions: A power transmission line foreign body removal device based on hot melt technology includes an inverted V-shaped bracket. The inverted V-shaped bracket plays a major supporting role in the entire device. The top of the inverted V-shaped bracket is hollowed out at the front and back. This design can reduce the weight of the entire device on the one hand, and is also convenient for the layout and heat dissipation of the internal lines on the other hand. Side plates are fixedly installed in parallel on both sides of the top of the inverted V-shaped bracket. Travel wheels are rotatably clamped between the front and rear ends of the side plates on both sides. The travel wheel is a key component for the movement of the device on the transmission line, which can bear the weight of the device and travel smoothly on the transmission line. The side plate is coaxially driven and installed with a travel motor on the outer side with the travel wheel. The travel motor provides power for the travel wheel, and is coaxially installed with the travel wheel to ensure the efficiency and stability of power transmission. A rotating base is fixedly installed on one side of the front end of the side plate. The rotating base is the installation base of the rotating bracket, and the rotating base is installed to rotate the rotating bracket in the horizontal direction. The rotating bracket can rotate in the horizontal direction, so as to adjust the position of the hot melt bracket and the resistance wire, so as to better remove foreign bodies on the transmission line. The rotating bracket is made of high-strength alloy material and has good rigidity and corrosion resistance. A rotating motor is fixedly installed on the upper end of the rotating base. The rotating motor provides power for the rotation of the rotating bracket and is fixedly installed on the upper end of the rotating base. A hot melt bracket is installed at the front end of the rotating bracket. The hot melt bracket is V-shaped and extends outward. Its design shape can better adapt to the shape of the power transmission line, increase the contact area between the resistance wire and the foreign matter, and thus improve the efficiency of foreign matter removal. The resistance wire is installed horizontally at the farthest end of the hot melt bracket. The resistance wire is the main tool for foreign matter removal. It generates high temperature by powering on and hot melts and removes foreign matter on the transmission line. An electric vortex spray is fixedly installed on the lower side of the front end of the rotating bracket. The electric vortex spray can generate a strong airflow to blow the hot-melted foreign matter away from the power transmission line. A pair of parallel guide plates are set on one side of the inverted V-shaped bracket. The function of the guide plate is to provide guidance for the sliding of the battery to ensure that the battery can move smoothly on the inverted V-shaped bracket. The battery is slidably installed between the guide plates. The battery provides power support for the entire device. The sliding installation design of the battery allows its position to be adjusted as needed to balance the center of gravity of the device. The battery displacement motor is installed in the battery side linkage. The battery displacement motor provides power for the movement of the battery and is installed in linkage with the battery to ensure that the battery can move smoothly between the guide plates.

[0011] The electric-controlled claw hook mechanism is fixedly installed at the top center of the inverted V-shaped bracket. The electric-controlled claw hook mechanism is a key component for connecting the device to the drone. It is fixedly installed at the top center of the inverted V-shaped bracket to ensure the stability and reliability of the connection. The electric-controlled claw hook mechanism cooperates with the forked hook installed at the bottom of the drone. The electric-controlled claw hook mechanism cooperates with the electric-controlled claw hook mechanism to achieve rapid connection and separation between the device and the drone.

[0012] The top front end of the inverted V-shaped bracket is fixedly mounted with a pan head base. The pan head base is the installation base of the camera pan head, which is fixedly mounted at the top front end of the inverted V-shaped bracket to ensure that the installation position of the camera pan head is accurate and stable. Connecting ears are arranged on both sides of the pan head base, and the camera pan head is connected to the connecting ears by rotation. The camera pan head can be rotated in the horizontal and vertical directions to adjust the shooting angle of the camera, so as to better observe the foreign matter on the transmission line.

[0013] A pan head motor is installed on the outside of the connecting ear, and the pan head motor drives the camera pan head. The pan head motor provides power for the rotation of the camera pan head and can control the rotation angle of the camera pan head.

[0014] The power transmission line foreign body removal device based on hot melt technology is characterized in that a rack extends from the side of the battery, the teeth of the rack face the V-shaped bracket and are meshed and connected with the gear on the top of the rotating shaft of the battery displacement motor.

[0015] The battery and the rotating bracket are respectively located on both sides of the inverted V-shaped bracket. This layout design can better balance the center of gravity of the device and improve the stability and reliability of the device.

[0016] The electric-controlled claw hook mechanism includes an electric-controlled claw hook bottom plate. A vertical axis extends upward from the center of the upper end of the electric-controlled claw hook bottom plate, and several horizontal axes extend outward from the upper part of the vertical axis. A claw hook with an upward opening is installed on the top of the horizontal axis. The upward opening design of the claw hook enables it to be quickly connected and separated from the bottom of the drone.

[0017] The bifurcated hook has several bifurcated shafts arranged outwardly, and the number of bifurcated shafts is equal to the number of claw hooks, which ensures that the connection between the device and the drone is stable and reliable.

[0018] The walking motor, rotating motor, resistance wire, electric turbojet, battery displacement motor and pan / tilt motor are all connected to the battery through internal circuits. The internal circuits use high-quality wires and cables to ensure the high efficiency and stability of power transmission.

[0019] The battery displacement motor and the rotating motor are started in association. This associated start design can better balance the center of gravity of the device and improve the stability and reliability of the device.

[0020] When the battery displacement motor is activated to rotate the rotating bracket outward, the battery displacement motor is activated to displace the battery toward the bottom of the inverted V-shaped bracket, and vice versa. This design can automatically adjust the position of the battery according to the working state of the device, ensuring that the center of gravity of the device is always kept within a reasonable range.

[0021] The bifurcated hook is a retractable structure that can be retracted and driven up and down. The design of the retractable structure makes the connection between the device and the drone more flexible and can adapt to different working environments and work requirements.

[0022] The device is equipped with a remote control component to achieve remote control. The remote control component adopts advanced wireless communication technology to achieve remote control of the device and improve work efficiency and safety.

[0023] The drone places the device on the transmission line, and the walking wheels between the side plates on both sides of the top of the inverted V-shaped bracket are clamped on the transmission line. The walking motor is started, and the walking wheels are driven coaxially with the walking wheels to provide power for the walking wheels, so that the device can move smoothly on the transmission line. During the movement, the camera head located at the front end of the top of the inverted V-shaped bracket can be driven by the pan-tilt motor to rotate in the horizontal and vertical directions, and the shooting angle of the camera installed on the camera head can be adjusted to observe the foreign objects on the transmission line in real time and transmit the picture back to the operator. When foreign objects are found, the rotating motor is started to drive the rotating bracket on the rotating base to rotate horizontally. The hot melt bracket at the front end of the rotating bracket extends outward in a V shape, and the resistance wire installed horizontally at its farthest end approaches the foreign object as the rotating bracket rotates. At the same time, since the battery displacement motor is started in conjunction with the rotating motor, when the rotating bracket rotates outward, the battery displacement motor is started to displace the battery toward the bottom side of the inverted V-shaped bracket to balance the center of gravity of the device. Conversely, when the rotating bracket rotates inward, the battery also moves in the opposite direction accordingly.

[0024] When the resistor wire is energized, it generates high temperature, melting the foreign matter on the transmission line. At the same time, the electric vortex sprayer fixed at the front end of the rotating bracket generates a strong airflow, blowing the melted foreign matter away from the transmission line, ensuring the thorough removal of foreign matter.

[0025] Compared with the prior art, the present invention has the following beneficial effects: The use of resistance wire hot-melt technology can quickly and effectively remove foreign objects on the transmission line. The resistance wire generates high temperature after being energized, and can efficiently handle foreign objects of different materials, greatly improving the efficiency of foreign object removal. In particular, the use of filamentary resistance wire has the characteristics of fast heating and small deformation. After power is turned on, the temperature can reach 450 degrees within 3 seconds, the expansion rate is only 7.8%, and it can be reused 100 times. The price of each resistance wire is only 6.2 yuan.

[0026] With the powerful airflow generated by the electric vortex spray, the foreign matter after heat melting is blown away from the power transmission line in time, ensuring the thoroughness of the foreign matter removal and avoiding the further harm of the residual foreign matter to the power transmission line.

[0027] The device moves on the transmission line through the travel motor to drive the travel wheel, which can quickly reach the location of the foreign object and improve work efficiency. At the same time, the position of the device can be adjusted at any time according to needs, which is convenient for handling foreign objects in different positions.

[0028] The rotating bracket can rotate in the horizontal direction, and can accurately adjust the position of the resistance wire and the electric vortex spray to better adapt to foreign objects of different shapes and positions, and improve the accuracy of the cleaning effect.

[0029] Driven by the pan / tilt motor, the camera pan / tilt can rotate in the horizontal and vertical directions, observe the foreign objects on the transmission line in real time, and provide accurate information to the operator for precise operation control.

[0030] The battery displacement motor is started in conjunction with the rotation motor. When the rotating bracket rotates, the battery is displaced accordingly, thereby automatically adjusting the center of gravity of the device to ensure the stability of the device during operation. This design avoids the device from tilting or falling due to an unstable center of gravity, and improves work safety.

[0031] The design of the inverted V-shaped bracket and the reasonable layout of various components provide a stable support structure for the device, enabling it to maintain smooth operation on the transmission line.

[0032] The device is connected to the drone through a retractable and electrically controlled claw hook mechanism. The connection method is simple and reliable, making it easy for the drone to carry the device to quickly reach the working position. The retractable structure makes the connection more flexible and adaptable to different working environments.

[0033] The remote control components are installed, and the operator can realize remote control, which greatly improves the convenience and safety of work. The operator does not need to approach the transmission line in person to operate, which reduces the risk of work. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solutions in the embodiments of the present invention will be fully described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] like Figure 1-3 As shown, a power transmission line foreign body removal device based on hot melt technology includes an inverted V-shaped bracket 1, and the top and back of the inverted V-shaped bracket 1 are hollowed out. It is characterized in that side panels 2 are fixedly installed in parallel on both sides of the top of the inverted V-shaped bracket 1, and a walking wheel 21 is rotatably clamped between the front and rear ends of the side panels 2 on both sides. A walking motor 211 is installed on the outer side of the side panel 2 coaxially with the walking wheel 21, a rotating base 61 is fixedly installed on one side of the front end of the side panel 2, and a rotating bracket 62 is rotatably installed on the rotating base 61 in the horizontal direction, and a rotating base 61 is fixedly installed on the upper end of the rotating base 61. Motor 65, a hot melt bracket 63 is installed at the front end of the rotating bracket 62, and the hot melt bracket 63 is V-shaped and extends outward, and a resistance wire 64 is installed horizontally at its farthest end, and an electric turbojet 8 is fixedly installed at the lower side of the front end of the rotating bracket 62; a pair of parallel guide plates 11 are arranged on one side surface of the inverted V-shaped bracket 1, and a battery 5 is slidably engaged between the guide plates 11, and a battery displacement motor 52 is installed next to the battery 5; an electric-controlled claw hook mechanism 3 is fixedly installed at the top center of the inverted V-shaped bracket 1, and the electric-controlled claw hook mechanism 3 cooperates with the forked hook 4 installed at the bottom of the drone.

[0037] A pan head base 71 is fixedly installed at the front end of the top of the inverted V-shaped bracket 1, and connecting ears are arranged on both sides of the pan head base 71. The connecting ears on both sides are rotatably connected to the camera pan head 72, and a pan head motor 73 is installed on the outer side of the connecting ears. The pan head motor 73 drives the camera pan head 72.

[0038] A rack 51 extends from the side of the battery 5 , and the teeth of the rack 51 face the V-shaped bracket 1 and mesh with the gear on the top of the rotating shaft of the battery displacement motor 52 .

[0039] The battery 5 and the rotating bracket 62 are respectively located on two sides of the inverted V-shaped bracket 1 .

[0040] The electric-controlled claw hook mechanism 3 includes an electric-controlled claw hook bottom plate 31 , a vertical axis extends upward from the center of the upper end of the electric-controlled claw hook bottom plate 31 , a plurality of horizontal axes extend outward from the upper part of the vertical axis, and a claw hook 32 with an upward opening is installed on the top of the horizontal axis.

[0041] The forked hook 4 has a plurality of forked shafts 41 arranged outwardly, and the number of the forked shafts 41 is equal to the number of the claw hooks 32 .

[0042] The walking motor 211, the rotating motor 65, the resistance wire 64, the electric turbojet 8, the battery displacement motor 52, and the pan / tilt motor 73 are all connected to the battery 5 via internal circuits.

[0043] The battery displacement motor 52 is started in conjunction with the rotating motor 65. When the battery displacement motor 52 is started to rotate the rotating bracket 62 outward, the battery displacement motor 52 is started to displace the battery 5 toward the bottom side of the inverted V-shaped bracket 1, and vice versa.

[0044] The bifurcated hook 4 is a telescopic structure and can be telescopically driven up and down.

[0045] The device is equipped with a remote control component to achieve remote control.

[0046] The specific working mode of the power transmission line foreign body removal device based on hot melt technology is as follows: First, the drone carrying the device is controlled by the remote control component to fly near the power transmission line. The retractable forked hook 4 at the bottom of the drone is connected with the electric-controlled claw hook mechanism 3 at the top center of the inverted V-shaped bracket 1 to ensure that the device is stably suspended under the drone. Among them, the several forked shafts 41 of the forked hook 4 arranged outward correspond to the claw hooks 32 of the electric-controlled claw hook mechanism 3 to achieve quick connection.

[0047] The rotating bracket 62 will block the inverted V-shaped bracket 1 from being placed on the transmission line. In order to solve this problem, an operation of rotating the rotating bracket 62 to one side is designed.

[0048] When the device needs to be placed on the transmission line, the rotating motor 65 is controlled to start, driving the rotating bracket 62 to rotate to one side, making room for placing the inverted V-shaped bracket 1 on the transmission line. At the same time, since the battery displacement motor 52 is started in conjunction with the rotating motor 65, when the rotating bracket 62 rotates, the battery displacement motor 52 is started to displace the battery 5 in the corresponding direction to change the center of gravity of the device and keep it stable.

[0049] When the rotating bracket 62 rotates outward, the battery displacement motor 52 starts to displace the battery 5 toward the bottom of the inverted V-shaped bracket 1. Ensure that the center of gravity of the device is always kept within a reasonable range during the adjustment of the position of the rotating bracket 62, and the device will not lose balance or become unstable due to the change in the position of the rotating bracket 62.

[0050] When the device is placed on the transmission line, the travel motor 211 is started to drive the travel wheel 21 to move smoothly on the transmission line. During the movement, the pan / tilt motor 73 drives the camera pan / tilt 72 to rotate, adjust the shooting angle of the camera, observe the foreign matter on the transmission line in real time, and transmit the picture back to the operator.

[0051] Once a foreign object is found, the rotating motor 65 is started, driving the rotating bracket 62 to rotate in the horizontal direction, so that the resistance wire 64 installed laterally at the farthest end of the hot melt bracket 63 is close to the foreign object. At the same time, since the battery displacement motor 52 is started in conjunction with the rotating motor 65, the battery displacement motor 52 causes the battery 5 to move toward the bottom side of the inverted V-shaped bracket 1 to balance the center of gravity of the device.

[0052] After the resistance wire 64 is energized, it generates high temperature to heat-melt the foreign matter on the transmission line. Then, the electric vortex spray 8 fixedly installed at the front end of the rotating bracket 62 generates a strong airflow to blow the hot-melted foreign matter away from the transmission line to ensure that the foreign matter is completely removed.

[0053] During the entire working process, the operator can adjust the operating status of each motor, as well as the working parameters of the resistance wire 64 and the electric vortex spray 8 at any time through the remote control component to ensure that the foreign matter removal work is carried out efficiently and safely.
