Description

Technical Field

[0001] This utility model relates to the field of high-voltage transmission line emergency repair technology, and in particular to a chute structure for tower repair using drones for high-voltage transmission lines. Background Technology

[0002] There are usually two methods for assembling emergency repair towers. First, after the emergency repair tower is assembled, it is erected as a whole using a drop-down A-frame support. Second, it is assembled by disassembly and reassembly, that is, the emergency repair tower is assembled from top to bottom, first the tower head, then the tower body, and finally the tower legs, until the entire tower is assembled. This is the reverse of the assembly sequence of other disassembly and reassembly methods.

[0003] Before selecting either of these two erection methods for tower construction, a detailed construction plan must be developed based on the structural characteristics of the emergency repair tower, the site terrain, and available equipment. Generally, these two methods have a longer construction period, require relatively high-quality site terrain (generally unsuitable for mountainous or forested areas), and involve a relatively large number of construction tools and personnel. When natural disasters damage power facilities and require the rapid erection of emergency repair towers to restore power transmission, the aforementioned traditional construction techniques cannot fully meet the requirements. Summary of the Invention The technical problem to be solved by this utility model is to provide a chute structure for tower repair using drones for high-voltage transmission lines. This overcomes the shortcomings of traditional tower erection methods, which have long construction cycles, relatively high requirements for site terrain, and a large demand for construction tools and personnel. This invention provides a modular and rapid assembly technology for drone-based tower repair.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a chute structure for tower repair using drones for high-voltage transmission lines, including a chute structure, a support structure at the bottom of the chute structure, and a base structure at the bottom of the support structure. The chute structure includes a four-sided pyramidal chute with a top opening larger than the bottom opening. The bottom of the four-sided pyramidal chute is provided with an installation frame, which is detachably connected to the top of the support structure by a first fastening bolt.

[0005] In a preferred embodiment, the support structure includes four first right-angle support plates, and adjacent first right-angle support plates are fixed together by second right-angle support plates and multiple second fastening bolts.

[0006] In a preferred embodiment, the base structure includes one or more detachable support frames, which are fixed together by a third right-angle support plate, a support frame, and multiple sets of third fastening bolts. The base structure is detachably connected to the bottom of the support structure by the third fastening bolts.

[0007] In a preferred embodiment, multiple corner brackets are mounted on the support frame via multiple third fastening bolts.

[0008] In a preferred embodiment, the quadrangular pyramidal chute is provided with multiple sets of weight-reducing slots. In a preferred embodiment, the quadrangular pyramidal chute is provided with multiple sets of reinforcing support plates.

[0009] In a preferred embodiment, the reinforcing support plate is drilled with lug holes for lifting.

[0010] In a preferred embodiment, the quadrangular pyramidal chute is made of stainless steel.

[0011] In a preferred embodiment, the inner wall of the quadrangular pyramidal chute is coated with polytetrafluoroethylene.

[0012] In a preferred embodiment, the surface of the polytetrafluoroethylene coating is polished.

[0013] The present invention provides a chute structure for high-voltage transmission line UAV emergency repair, which has the following advantages: (1) The time flow of module docking and installation work for a single emergency repair is greatly reduced. Compared with the traditional method, the manpower requirement is greatly reduced and the work efficiency is greatly improved.

[0019] Example 1: like Figure 1-4 This invention discloses a chute structure for high-voltage transmission line tower repair using drones. Specifically designed for drone-based tower repair scenarios, this structure enables precise transport and positioning of repair materials, effectively solving the problem of inconvenient material transfer during traditional tower erection. It includes a chute structure 1, which serves as the core channel for material transport, primarily receiving and guiding repair materials, such as connectors and small components required for tower assembly, delivered by the drone to the site. This ensures the materials slide stably along a pre-set path to the designated assembly position. A support structure 2 is installed at the bottom of the chute structure 1, acting as a bridge connecting the chute structure 1 and a base structure 3. This support structure 2 also provides stable vertical support to the chute structure 1, preventing tilting or displacement when carrying materials. The base structure 3 is directly in contact with the ground, distributing the weight of the entire chute structure evenly across the ground, enhancing the stability of the overall structure in complex terrain and adapting to diverse ground conditions at the repair site. The chute structure 1 includes a pyramidal chute 4 with a larger opening at the top than at the bottom. This pyramidal design expands the material receiving area at the top, facilitating accurate material delivery by the drone. Simultaneously, the smaller opening at the bottom allows for concentrated material output, preventing spillage during transport. The bottom of the pyramidal chute 4 is equipped with a mounting frame 5, a ring-shaped frame structure. The inner side of the frame is fixedly connected to the bottom edge of the pyramidal chute 4, while the outer side has connection holes adapted to the top of the support structure 2. The mounting frame 5 is detachably connected to the top of the support structure 2 via a first fastening bolt 7. This detachable design allows for rapid assembly and disassembly on-site according to actual needs, reducing transportation and storage difficulties, and also facilitating later maintenance or replacement of individual components.

[0020] In a preferred embodiment, the support structure 2 includes four right-angled support plates 9, which are symmetrically distributed to form the main frame of the support structure 2. The two right-angled sides of each right-angled support plate 9 are respectively arranged along the horizontal and vertical directions to ensure good load-bearing capacity and deformation resistance. Adjacent right-angled support plates 9 are fixed together by second right-angled support plates 9 (presumably a supplementary description, where the second right-angled support plate is structurally compatible with the first right-angled support plate to enhance the connection strength between adjacent right-angled support plates 9) and multiple second fastening bolts 11. The multiple second fastening bolts 11 are evenly distributed along the length of the second right-angled support plates 9, making the connection between adjacent right-angled support plates 9 more secure, effectively improving the overall stability and load-bearing capacity of the support structure 2, and preventing the support structure 2 from shaking or being damaged when carrying materials in the chute structure 1.

[0021] In a preferred embodiment, the base structure 3 includes one or more freely detachable support frames 12. Each support frame 12 is a rectangular frame structure, and the number of support frames 12 can be flexibly selected and combined for installation according to the site area, terrain undulations, and overall structural load-bearing requirements to adapt to different emergency repair site conditions. Multiple support frames 12 are fixed together via a third right-angle support plate 13, a support frame 16, and multiple sets of third fastening bolts 15. The third right-angle support plate 13 is connected to the corners of adjacent support frames 12, and the support frame 16 is arranged along the length or width of the support frame 12, forming a mesh reinforcement structure in conjunction with the third right-angle support plate 13. Multiple sets of third fastening bolts 15 pass through the connection holes of the third right-angle support plate 13, the support frame 16, and the support frame 12, achieving a tight connection between the multiple support frames 12 and ensuring the overall integrity and stability of the base structure 3. The base structure 3 is connected to the bottom of the support structure 2 by the third fastening bolt 15, which facilitates the adjustment of the connection position between the support structure 2 and the base structure 3 according to the on-site assembly height requirements, and also facilitates disassembly and transportation later. In a preferred embodiment, multiple corner brackets 14 are installed on the support frame 12 by multiple third fastening bolts 15. The corner brackets 14 have a right-angled triangular structure, and their two right-angled sides are fixedly connected to the adjacent frame of the support frame 12, which can enhance the structural strength at the corners of the support frame 12, avoid stress concentration at the corners of the support frame 12 when bearing weight, which may lead to deformation or breakage, and further improve the durability of the base structure 3. In the preferred embodiment, the quadrangular pyramidal chute 4 is provided with multiple sets of weight-reducing slots 6, which are evenly distributed on the four sides of the quadrangular pyramidal chute 4. Under the premise of ensuring that the structural strength of the chute meets the usage requirements, the overall weight of the quadrangular pyramidal chute 4 can be effectively reduced, the load on the supporting structure 2 can be reduced, and it is also convenient for operators to handle and assemble the chute structure 1, thereby improving on-site construction efficiency. In a preferred embodiment, the quadrangular pyramidal chute 4 is provided with multiple sets of reinforcing support plates 8. The reinforcing support plates 8 are spaced apart along the height direction of the quadrangular pyramidal chute 4, and at least one set is provided on each side. One end of the reinforcing support plate 8 is fixedly connected to the inner wall of the quadrangular pyramidal chute 4, and the other end extends to the edge of the chute opening. This can enhance the deformation resistance of the quadrangular pyramidal chute 4, avoid problems such as side wall dents and bending during material impact or long-term use, and extend the service life of the chute structure 1. In the preferred embodiment, the reinforcing support plate 8 is drilled with ear holes for lifting. The ear holes are located at the ends of the reinforcing support plate 8 and are symmetrically distributed, which makes it convenient for operators to use lifting equipment (such as small cranes, hand chain hoists, etc.) to lift the chute structure 1. Especially when the chute structure needs to be installed at a higher position at the repair site, lifting through the ear holes can reduce the difficulty and safety risks of manual handling and improve the ease of assembly. In the preferred embodiment, the quadrangular pyramidal chute 4 is made of a material with good wear resistance and corrosion resistance. This material can resist the damage to the inner wall of the chute caused by rainwater, dust and material friction that may exist at the repair site, ensuring that the chute can be used stably in different environments and reducing the later maintenance costs. In a preferred embodiment, the inner wall of the quadrangular pyramidal chute 4 is provided with a coating having a low coefficient of friction. This coating can reduce the friction between the material and the inner wall when the material slides down in the chute, prevent the material from being stuck in the chute due to excessive friction, ensure that the material can slide smoothly to the designated position, improve the material conveying efficiency, and at the same time reduce the friction loss between the material and the inner wall of the chute, protecting the material and the chute structure. In a preferred embodiment, the coating surface is polished, which further reduces the roughness of the coating surface, making the resistance when the material slides down less. It also facilitates the later cleaning of dust or material debris remaining on the inner wall of the chute, keeping the inside of the chute clean and preventing residual debris from affecting the subsequent material conveying. Example 2: like Figure 1-4 The working principle of this utility model is as follows: Based on the terrain conditions at the repair site, the location of the tower assembly, and the material delivery requirements of the drone, the support frame 12 of the base structure 3 is first assembled and installed using the third right-angle support plate 13, the support frame 16, and the third fastening bolt 15 to ensure that the base structure is in stable contact with the ground and that the weight is evenly distributed. Subsequently, the four first right-angle support plates 9 of the support structure 2 are assembled into the main frame through the second right-angle support plates and the second fastening bolts 11. The top of the support structure 2 is then connected and fixed to the mounting frame 5 at the bottom of the chute structure 1 through the first fastening bolts 7. At the same time, it is ensured that the bottom of the support structure 2 is tightly connected to the base structure 3 through the third fastening bolts 15. This completes the on-site assembly of the entire chute structure. The installation height and position of the chute structure can be adjusted using lifting equipment through the ear holes on the reinforcing support plate 8. Based on the emergency repair needs, the drone carries the materials required for tower assembly (such as connectors, small components, etc.) and flies to the top of the chute structure 1, precisely dropping the materials into the four-sided pyramidal chute 4. Because the top opening of the four-sided pyramidal chute is large, it can effectively receive the materials dropped by the drone, preventing them from scattering. The inner wall of the chute is coated with a polished low-friction coating, allowing the material to slide smoothly down the inner wall of the chute under its own gravity, reducing the problem of stagnation caused by friction; the smaller opening at the bottom guides the material to the designated position for tower assembly, allowing construction workers to quickly pick it up for tower assembly operations. During material conveying, the first right-angle support plate 9 and the second right-angle support plate of the support structure 2 cooperate to provide stable vertical support for the chute structure 1, preventing the chute from tilting due to material impact or its own weight; the support frame 12 and corner support plate 14 of the base structure 3 enhance the overall structure's resistance to deformation, evenly transferring the weight of the entire chute structure to the ground, ensuring that the structure remains stable even in complex terrain; the reinforced support plate 8 on the four-sided pyramidal chute 4 further improves the chute's resistance to deformation, while the weight-reducing chute opening 6 reduces the structural weight while ensuring strength, reducing the support burden, and together ensuring the continuous stability of the material conveying process, helping the emergency repair tower to be quickly erected to restore power transmission.

[0022] The beneficial effects of this utility model are: the time flow for module docking and installation in a single emergency repair is greatly reduced, the manpower requirement is greatly reduced and the work efficiency is greatly improved compared with the traditional method; the prefabricated components are easy to disassemble and assemble, and can be flexibly prefabricated according to the needs of existing modules, with strong combination flexibility; the overall structure of the device is reliable and stable, convenient to disassemble and use, and highly practical.
