Description

Technical Field

[0001] The present invention relates to a portable high-voltage wire obstacle removal drone combination device, belonging to the technical field of power system transmission line maintenance equipment. Background Art

[0002] In the power system, high-voltage transmission lines are widely distributed and exposed to the natural environment for a long time. Various obstacles, such as plastic bags, kite strings, and tree branches, often wind around the wires. These obstacles not only affect the normal operation of the transmission line but also may cause safety accidents such as short circuits and tripping, seriously threatening the stability and safety of power supply. Currently, the following methods are mainly used for high-voltage wire obstacle removal: 1. Manually climbing the electric pole for obstacle removal: This method has a high labor intensity, low work efficiency, and the operators need to work at high altitude, facing great safety risks. Especially in bad weather conditions, the operation difficulty and danger are further increased. 2. Using an insulating rod for obstacle removal: The length of the insulating rod is limited, and it is difficult to reach obstacles at higher positions or farther distances, so the obstacle removal range is greatly limited. 3. Traditional drone for obstacle removal: The existing obstacle removal drones are large in size, inconvenient to carry and transport, and it is difficult to quickly reach the operation site in some areas with complex terrain or inconvenient transportation; moreover, the obstacle removal functions of some drones are single, and the removal effects on different types of obstacles are not good. Summary of the Invention

[0003] To solve the above technical deficiencies, the present invention provides a portable high-voltage wire obstacle removal drone combination device to solve the problems existing in the existing obstacle removal methods, such as high labor intensity, high safety risk, limited obstacle removal range, and inconvenient carrying, and to achieve efficient, safe, and convenient high-voltage wire obstacle removal operations.

[0004] The present invention is achieved by the following measures:

[0005] A portable high-voltage wire obstacle removal drone combination device includes a drone and a square box body. The box body includes a box bottom and a box cover. The box bottom includes a long central bottom plate extending along the central axis and side bottom plates symmetrically hinged on both sides of the central bottom plate. The bottom of the drone is fixed above the central bottom plate. A hollow window is left in the middle of the side bottom plate, and a clamping component and a fusing component are detachably connected in the window;

[0006] The clamping component includes a ejector rod and a connecting rod that can be threadedly connected. A plurality of elastic claw strips are axially extended at the top of the ejector rod, arranged in a circle, and the ends can open outwards. A limiting ring is fixed on the ejector rod below the elastic claw strips. A gathering sleeve is slidably sleeved on the ejector rod between the limiting ring and the elastic claw strips. A compression spring is sleeved on the ejector rod between the limiting ring and the gathering sleeve. An electromagnetic chuck is arranged on the ejector rod below the limiting ring. A sliding ring that can be adsorbed by the electromagnetic chuck is slidably sleeved on the ejector rod between the electromagnetic chuck and the limiting ring. A plurality of pulling ropes are connected between the sliding ring and the gathering sleeve, and the pulling ropes movably penetrate through the limiting ring; when the electromagnetic chuck adsorbs the sliding ring, the gathering sleeve is pulled down to the lower end of the sliding stroke and the elastic claw strips open outwards; when the electromagnetic chuck does not adsorb the sliding ring, the gathering sleeve is bounced to the upper end of the sliding stroke by the compression spring and the elastic claw strips gather towards the center inside the gathering sleeve; the fusing component includes a support rod and a mounting rod that can be threadedly connected. A fusing heating wire is arranged at the top of the mounting rod; a storage battery is arranged on the central bottom plate, and the storage battery is connected to the electromagnetic chuck and the fusing heating wire through wires. A connecting sleeve that can be threadedly connected to the connecting rod and the support rod is arranged at the end of the central bottom plate.

[0007] Four support rods are axially extended at the top of the above-mentioned mounting rod, arranged evenly in a circle, and the ends can open outwards. The lower ends of the four support rods are hinged to the mounting rod, and a tension spring that can pull the support rods outwards is connected between the upper ends of the four support rods and the middle part of the mounting rod. A fusing heating wire is connected between the upper ends of two opposite support rods.

[0008] Slots are opened at the edges of the side bottom plates at both ends of the above-mentioned window, and the ends of the ejector rod, connecting rod, support rod, and mounting rod are stuck in the slots.

[0009] The central bottom plate and the side bottom plates are hinged and provided with a locking mechanism. The box cover is buckled on the box bottom, and a lock is arranged between the box cover and the box bottom.

[0010] The beneficial effects of the present invention are as follows: 1.

Detailed implementation manners

[0018] The following further describes the present invention in detail with reference to the accompanying drawings:

[0019] As Figure 1-6 shown, a portable high-voltage wire obstacle clearing unmanned aerial vehicle combination device includes an unmanned aerial vehicle 7 and a square box body. The box body includes a box bottom and a box cover 1. The box bottom includes a long strip-shaped central bottom plate 2 extending along the central axis and side bottom plates 3 symmetrically hinged on both sides of the central bottom plate 2. The bottom of the unmanned aerial vehicle is fixed above the central bottom plate 2. A hollow window is left in the middle of the side bottom plate 3, and a clamping component 4 and a fusing component 5 are detachably connected in the window.

[0020] The clamping component 4 includes a ejector rod 4.2 and a connecting rod 4.1 that can be threadedly connected. At the top of the ejector rod 4.2, several elastic claw strips 4.9 are axially extended in a circle and the ends of which can open outwards in all directions. A limiting ring 4.6 is fixed on the ejector rod 4.2 below the elastic claw strips 4.9. A gathering sleeve 4.8 is slidably sleeved on the ejector rod 4.2 between the limiting ring 4.6 and the elastic claw strips 4.9. A compression spring 4.7 is sleeved on the ejector rod 4.2 between the gathering sleeve 4.8 and the limiting ring 4.6. An electromagnetic chuck 4.3 is arranged on the ejector rod 4.2 below the limiting ring 4.6. A sliding ring 4.4 that can be adsorbed by the electromagnetic chuck 4.3 is slidably sleeved on the ejector rod 4.2 between the electromagnetic chuck 4.3 and the limiting ring 4.6. Several pulling ropes 4.5 are connected between the sliding ring 4.4 and the gathering sleeve 4.8, and the pulling ropes 4.5 movably penetrate through the limiting ring 4.6; when the electromagnetic chuck 4.3 adsorbs the sliding ring 4.4, the gathering sleeve 4.8 is pulled down to the lower end of the sliding stroke and the elastic claw strips 4.9 open outwards in all directions; when the electromagnetic chuck 4.3 does not adsorb the sliding ring 4.4, the gathering sleeve 4.8 is bounced to the upper end of the sliding stroke by the compression spring 4.7 and the elastic claw strips 4.9 gather towards the center and are within the gathering sleeve 4.8.

[0021] The fusing component 5 includes a support rod 5.1 and a mounting rod 5.2 that can be threadedly connected. A fusing heating wire 5.5 is arranged at the top of the mounting rod 5.2; a storage battery is arranged on the central bottom plate 2, and the storage battery is connected to the electromagnetic chuck 4.3 and the fusing heating wire 5.5 through wires. A connecting sleeve 6 that can be threadedly connected to the connecting rod 4.1 and the support rod 5.1 is arranged at the end of the central bottom plate 2. Four support rods 5.4 that are evenly arranged in a circle and the ends of which can open outwards in all directions are axially extended at the top of the mounting rod 5.2. The lower ends of the four support rods 5.4 are hinged to the mounting rod 5.2, and a tension spring 5.3 that can pull the support rods 5.4 outwards is connected between the upper ends of the four support rods 5.4 and the middle part of the mounting rod 5.2. The fusing heating wire 5.5 is connected between the upper ends of two opposite support rods 5.4. Card slots 8 are formed at the edges of the side bottom plates 3 at both ends of the window, and the ends of the ejector rod 4.2, the connecting rod 4.1, the support rod 5.1, and the mounting rod 5.2 are stuck in the card slots 8. The central bottom plate 2 and the side bottom plates 3 are hinged and provided with a locking mechanism. The box cover 1 is buckled on the box bottom, and a lock catch is arranged between the box cover 1 and the box bottom.

[0022] The drone adopts a foldable frame design. The frame is made of lightweight and high-strength carbon fiber material, which reduces the overall weight while ensuring the structural strength. Each arm of the frame is connected to the fuselage through a rotatable joint. When stored, the arms can be folded near the fuselage, reducing the overall volume of the drone and making it convenient to carry. It is equipped with multiple high-performance brushless motors and propellers. The motors are installed at the ends of the arms, providing flight power for the drone. The motors are electrically connected to the control system, and the rotation speed of the motors is adjusted through the control system to achieve flight postures such as takeoff, landing, hovering, forward movement, backward movement, left and right movement of the drone.

[0023] When in use, open the box cover 1 to expose the drone, and then remove the clamping component 4 and the fusing component 5 from the window position. According to the need, use the clamping component 4 or the melting point component to remove obstacles. When using the clamping component 4, thread the ejector rod 4.2 and the connecting rod 4.1 together and install the end of the connecting rod 4.1 on the connecting sleeve 6, and then connect the battery to the electromagnet suction cup 4.3 through a wire. The side bottom plate 3 is folded downwards and locked. At this time, the two side bottom plates 3 act as landing gears to support the drone. Moreover, since there is a hollow window in the middle of the side bottom plate 3, the weight can be reduced. When the drone flies near the high-voltage line, control the on-off of the electromagnet suction cup 4.3 through the switch. When the electromagnet suction cup 4.3 is energized, the electromagnet suction cup 4.3 adsorbs the sliding ring 4.4 downwards. The sliding ring 4.4 slides the gathering sleeve 4.8 downwards to the lowest end through the pulling rope 4.5. At this time, the compression spring 4.7 is in a compressed state, and the elastic claw strips 4.9 are also in an open state. When the obstacle hanging on the high-voltage line is located between the elastic claw strips 4.9, the electromagnet suction cup 4.3 is powered off, and the electromagnet suction cup 4.3 loses magnetism. Under the action of the compression spring 4.7, the gathering sleeve 4.8 slides up to the top, and the gathering sleeve 4.8 gathers the elastic claw strips 4.9 into the gathering sleeve 4.8, thereby clamping the obstacle. When using the fusing component 5, thread the support rod 5.1 and the mounting rod 5.2 together and install the end of the support rod 5.1 on the connecting sleeve 6, and then connect the battery to the fusing heating wire 5.5 through a wire. When the drone approaches the obstacle on the high-voltage line, use the fusing heating wire 5.5 to fuse the obstacle. After use, land the drone on the ground, then retract the side bottom plate 3, and clamp the ends of the ejector rod 4.2, the connecting rod 4.1, the support rod 5.1 and the mounting rod 5.2 in the card slots 8 on the edge of the window, so as to store the clamping component 4 and the fusing component 5. Finally, buckle the box cover 1 to facilitate handling and avoid collision damage to the drone during handling. The box body is made of high-strength plastic and has the functions of waterproof, dustproof and shockproof. The box cover 1 and the box bottom can be fixed together in the form of elastic straps or buckles.

[0024] A flight controller, an obstacle detection sensor, and a wireless communication module are set in the drone, and a ground control terminal is matched. The flight controller is the core control component of the drone, responsible for processing data from various sensors and instructions from the ground control terminal, and controlling the flight attitude of the drone and the actions of the obstacle clearing device. The obstacle detection sensors are installed at the front end and around the drone. By combining lidar and cameras, they can detect obstacle information in front of and around the drone in real time and transmit the data to the flight controller. The wireless communication module enables communication between the drone and the ground control terminal. The ground control terminal can be a mobile phone, a tablet computer, or a dedicated remote control. Through the ground control terminal, the operator can monitor the flight status and obstacle clearing situation of the drone in real time and send control instructions. The frame of the drone body is made of T700-grade carbon fiber material, which has the characteristics of high strength and low density, and can reduce the weight while ensuring the strength of the frame. Assemble each component according to the design requirements to ensure firm connections and normal electrical connections between components. After assembly, conduct a comprehensive commissioning of the drone, including flight attitude commissioning, obstacle clearing device action commissioning, sensor calibration, etc., to ensure the normal operation of all functions of the drone.

[0025] The above are only the preferred embodiments of this patent. It should be noted that for those of ordinary skill in the art, without departing from the principle of this patent technology, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of this patent.
