Description

Technical Field

[0001] This invention relates to the field of high-strength composite pole technology, specifically to high-strength composite material poles and their preparation methods. Background Technology

[0002] Utility poles are supporting poles used in overhead power transmission lines to support the transmission lines. During use, a cabinet is usually equipped on one side of the pole. The circuit components inside the cabinet are connected to the communication lines on the pole via wires. Common types of utility poles include wooden poles, concrete poles, and composite material poles. Concrete poles are made of concrete and steel bars or wires, and there are prestressed and non-prestressed types. Composite material poles are a new type of pole that, compared to traditional concrete poles, have good insulation, corrosion resistance, and heat resistance.

[0003] Because composite material poles are large in size, they are usually divided into several sections during the initial installation process to facilitate transportation. After the sections of composite material poles are transported to the designated location, they are then installed. The traditional installation method has poor structural stability and the installation steps are relatively complicated. Summary of the Invention

[0004] This invention proposes a high-strength composite material pole and its preparation method, which solves the problems of poor structural stability and cumbersome installation steps in the traditional installation method of composite material poles in related technologies.

[0005] The technical solution of the present invention is as follows: High-strength composite material poles, including: First subject; A plurality of second bodies are provided, one end of the first body and one end of the plurality of second bodies are provided with a snap-fit ​​groove, and the other end of the plurality of second bodies is provided with a snap-fit ​​protrusion. The first body and the plurality of second bodies are connected in sequence, and the snap-fit ​​protrusion is located in the snap-fit ​​groove, and the shape of the snap-fit ​​protrusion matches that of the snap-fit ​​groove.

[0006] As a further technical solution, both the first body and the second body are cylindrical, and the snap-fit ​​protrusion includes: The cylindrical portion, the projection of which is located within the projection of the first main body or the second main body.

[0007] As a further technical solution, the snap-fit ​​protrusion also includes: Several plates are disposed on the columnar portion, and the plates are arranged along the circumference. The plates are rectangular.

[0009] As a further technical solution, it also includes: The base has an opening slot, and the first main body is rotatably mounted on the base and located in the opening slot. After the first main body is rotated, the first main body and several second main bodies are arranged vertically.

[0010] As a further technical solution, the first main body has a rotating shaft portion, the base has a bearing hole, the rotating shaft portion is disposed within the bearing hole, the width of the bearing hole is greater than the diameter of the rotating shaft portion, and further includes: Two support members are movably disposed within the support hole. After the two support members move, they move closer to or further away from each other. A pivot groove is formed between the top of the two support members and the inner wall of the support hole. A pivot sliding groove is formed between the two support members. The two support members are configured to move closer to or further away from each other after the first body rotates.

[0011] As a further technical solution, there are multiple connecting rods, with one connecting rod slidably disposed within each channel.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-8 As shown, this embodiment proposes a high-strength composite material pole, including: First subject 1; A plurality of second bodies 2, one end of the first body 1 and one end of the plurality of second bodies 2 each have a snap-fit ​​groove 3, and the other end of the plurality of second bodies 2 each has a snap-fit ​​protrusion 4. The first body 1 and the plurality of second bodies 2 are connected in sequence, and the snap-fit ​​protrusion 4 is located in the snap-fit ​​groove 3. The snap-fit ​​protrusion 4 and the snap-fit ​​groove 3 are shaped to match.

[0019] In this embodiment, as Figures 1-3As shown, the segmented pole is divided into a first main body 1 and several second main bodies 2, which are connected sequentially to complete the installation of the entire high-strength composite material pole. During installation, they are first connected horizontally in sequence, as shown below. Figure 2 As shown, after installation, using a crane or other device, after the base 7 is installed, the second main body 2, which is away from the base 7, is lifted to control the entire high-strength composite material pole to be arranged vertically, and finally fix the position of the first main body 1 at the bottom inside the base 7, for example, by using some stop blocks with threaded connections to restrict movement.

[0020] Furthermore, to ensure a stable connection between the first main body 1 and the second main body 2 or between two second main bodies 2, the design includes a snap-fit ​​groove 3 at one end of the first main body 1 and at one end of several second main bodies 2, and a snap-fit ​​protrusion 4 at the other end of several second main bodies 2. This connection is achieved by using snap-fit ​​protrusions 4 with matching shapes to snap-fit ​​grooves 3.

[0021] Furthermore, both the first body 1 and the second body 2 are cylindrical, and the snap-fit ​​protrusion 4 includes: The cylindrical portion 401 is projected within the projection of the first main body 1 or the second main body 2.

[0022] Furthermore, the snap-fit ​​protrusion 4 also includes: Several plates 402 are disposed on the columnar portion 401, and the plates 402 are arranged along the circumference. The plates 402 are rectangular.

[0023] In this embodiment, as Figure 2 , 3 As shown in Figure 6, utility poles are typically cylindrical. To further define the snap-fit ​​structure and improve connection stability, the snap-fit ​​protrusion 4 is designed to include a cylindrical portion 401 located at the center and several plates 402 arranged circumferentially around it, forming a cross-like structure. At the same time, the snap-fit ​​protrusion 4 and the snap-fit ​​groove 3 are interference-fitted. To further prevent the position of the plates 402 from being occupied by the cylindrical portion 401, the projection of the cylindrical portion 401 is set to be located within the projection of the first main body 1 or the second main body 2. The snap-fit ​​is achieved by splicing and interference fit, improving the convenience of rapid installation in the early stage.

[0024] Furthermore, both the first body 1 and the second body 2 have a channel 5, which penetrates the cylindrical portion 401 and communicates with the snap-fit ​​groove 3, and further includes: Connecting rod 6, which is disposed within the channel 5.

[0025] In this embodiment, since the entire high-strength composite material pole is a multi-segment connection, its overall structure still needs to be a through-type structure to further improve stability. Using a principle similar to reinforced concrete, channels 5 are opened in all the first main body 1 and the second main body 2, and connecting rods 6 are installed through the channels 5. In order to avoid the cylindrical part 401 located in the center of the snap-fit ​​protrusion 4 from obstructing the use of the connecting rods 6, the channels 5 also need to pass through the cylindrical part 401. The use of connecting rods 6 improves the stability of the entire high-strength composite material pole.

[0026] Furthermore, it also includes: The base 7 has an opening groove 701. The first body 1 is rotatably mounted on the base 7 and located in the opening groove 701. After the first body 1 is rotated, the first body 1 and several second bodies 2 are arranged vertically.

[0027] In this embodiment, as Figure 2 , 7 As shown, a base 7 is installed to first stabilize the foundation. At the same time, in order to facilitate the use of cranes and other equipment to lift the entire high-strength composite material pole and distribute it vertically, the first main body 1 is set to rotate in the opening slot 701 of the base 7. First, the foundation position of the base 7 is fixed. Finally, when using the crane, only one end of the crane is needed to ensure that after the first main body 1 rotates, the first main body 1 and several second main bodies 2 are arranged vertically, thus completing the installation of the pole.

[0028] Furthermore, the first main body 1 has a pivot portion 8, the base 7 has a bearing hole 702, the pivot portion 8 is disposed within the bearing hole 702, the width of the bearing hole 702 is greater than the diameter of the pivot portion 8, and further includes: Two support members 9 are movably disposed within the support hole 702. After the two support members 9 move, they move closer to or further away from each other. A pivot groove 10 is formed between the top of the two support members 9 and the inner wall of the support hole 702. A pivot sliding groove 11 is formed between the two support members 9. The two support members 9 are configured to move closer to or further away from each other after the first main body 1 rotates.

[0029] In this embodiment, as Figure 7 , 8As shown, the rotation of the first main body 1 is achieved through the rotating shaft 8, which is rotatably installed in the bearing hole 702 of the base 7. This shaft 8 provides stable support and, by utilizing the pressure exerted on the base 7 after the entire high-strength composite material pole is arranged vertically, controls the sliding of the connecting rod 6 within the channel 5, thus allowing it to pass through the entire channel 5 and improving stability. Therefore, to coordinate with the movement of the connecting rod 6, two movable bearing members 9 are designed within the bearing hole 702, which can move closer to or further away from each other. During the initial horizontal installation, the weight acting on the base 7 is only that of the first main body. 1. At this time, the rotating shaft 8 can rotate stably in the rotating shaft groove 10 formed between the top of the two bearing members 9 and the inner wall of the bearing hole 702. When the entire high-strength composite material pole is arranged vertically, the pressure increases, which in turn squeezes the two bearing members 9 apart, causing the rotating shaft to slide downward in the rotating shaft sliding groove 11. During this process, the protrusion 12 located at the bottom of the base 7 will contact and act on the connecting rod to achieve the entire through. The movement of the two bearing members 9 can be achieved by elastic members. As long as a spring with appropriate elasticity is arranged in advance, it can be ensured that the bearing members 9 move stably in the bearing hole 702.

[0030] Furthermore, there are multiple connecting rods 6, with one connecting rod 6 slidably disposed within each channel 5. The length of the first body 1 is equal to the length of the second body 2. The length of the connecting rod 6 is the sum of the length of the first body 1 and the depth of the locking groove 3. It also includes: A protrusion 12 is disposed at the bottom of the base 7 and located within the opening groove 701. The protrusion 12 is used to push the connecting rod 6 to slide.

[0031] In this embodiment, as Figure 7 , 8 As shown, the connecting rod 6 is divided into several parts. To ensure the above functions can be achieved, a connecting rod 6 is slidably installed in a channel 5. The length of the first body 1 is equal to the length of the second body 2. The length of the connecting rod 6 is the sum of the length of the first body 1 and the depth of the locking groove 3. This ensures that the protrusion 12 plays its role. When the locking protrusion 4 is locked in the locking groove 3, a part of the connecting rod 6 is just locked into the channel 5 of the adjacent body, completing the connection. At the same time, the connecting rods 6 in the adjacent body will also continue to move under the action of the corresponding connecting rod 6, quickly completing the overall connection and improving the convenience and stability of the overall installation.

[0032] Furthermore, the plate 402 has a gap 403 and also includes: The locking component 13 is slidably disposed within the channel 5 of the cylindrical portion 401. The locking component 13 has a locking part 14 located within the gap 403. After the connecting rod 6 slides, it drives the locking part 14 to slide.

[0033] Furthermore, both the first main body 1 and the second main body 2 are made of fiberglass.

[0034] In this embodiment, the entire high-strength composite material pole is made of fiberglass, which has advantages such as lightweight, high strength, corrosion resistance, insulation, wind resistance, and low installation cost. To further utilize the sliding action of several connecting rods 6 to simultaneously improve the connection stability of adjacent main bodies, gaps 403 are opened on the circumferentially arranged plates 402, and a clip 13 and a clip 14 that are simultaneously clipped into the gap 403 are slidably installed in the channel 5 of the cylindrical part 401. When the connecting rod 6 slides, it will first act on the clip 13, and then act on the connecting rod 6 of the adjacent main body. When acting on the clip 13, the clip 13 continues to slide, driving the clip 14 to continue into the gap 403. Due to the overall fiberglass material and the interference fit, the connection between adjacent main bodies is more stable. The sliding of the connecting rod 6 can improve both the overall stability and the connection stability of adjacent main bodies.

[0035] The manufacturing method of high-strength composite material poles, using high-strength composite material poles, includes the following steps: S1, Fixed base 7; S2. Connect the first main body 1 and several second main bodies 2, and snap-fit ​​protrusion 4 is snapped into snap-fit ​​groove 3; S3. Rotate the first main body 1 and fix the position of the first main body 1.

[0036] The above are merely preferred embodiments of the present invention and are 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.
