Description

Technical Field

[0001] This utility model relates to the field of utility pole technology, specifically a novel series-connected composite utility pole. Background Technology

[0002] As a crucial supporting structure for power transmission, utility poles are a vital component. Types of utility poles include wooden poles, concrete poles, steel tower poles, and composite material poles. Among these, wooden poles have relatively low strength and poor durability.

[0003] For example, the polyurethane composite series pole and its connection method disclosed in publication number "CN118481400A" uses a perforated pole body prepared with a special process and special bolts. During installation, it can be completed simply by connecting the poles and fixing them with special bolts. Its connection structure is simple, which can greatly simplify construction and improve assembly efficiency. Finally, the simple glue injection process can further improve the connection strength and construction quality. However, in this polyurethane composite series pole and its connection method, the upper pole body is connected to the lower pole body, and the holes of the upper and lower pole bodies are not easy to align, requiring a long time to complete the connection and fixing of the upper and lower pole bodies. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the upper pole section is sleeved onto the lower pole section, the holes of the upper pole section and the lower pole section are not easy to align, and it takes a long time to complete the series connection and fixing work of the upper pole section and the lower pole section. Therefore, a new series-connected composite pole is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel series-connected composite pole is designed, comprising a lower pole body and an upper pole body, wherein the lower pole body and the upper pole body are fitted together. The lower pole body has an internal mounting structure, which includes a limiting block and limiting posts. The outer wall of the limiting block is inserted into a limiting groove, and the inner wall of the limiting block is machined with a first through hole. Multiple limiting posts are inserted into limiting holes, and the limiting groove is machined in the middle of the inner wall of the lower pole body.

[0007] Preferably, the plurality of limiting holes are machined at the edge of the inner wall of the lower section rod, and bolts are provided inside the first through hole and the second through hole.

[0008] Preferably, the upper ends of the limiting block and the limiting post are both fixedly connected to the upper section of the rod.

[0009] Preferably, the second through hole is machined on both sides of the inner wall of the lower section of the rod, and a rubber pad is sleeved on the outer wall of the bolt.

[0010] Preferably, the rubber pad is pressed against the lower rod and the nut on both sides, and the inner wall of the nut is threadedly connected to the bolt.

[0011] This utility model proposes a novel series-connected composite pole, which has the following advantages: through the cooperation of the lower pole body, the upper pole body, and the installation structure, the limiting block enters the limiting groove, and multiple limiting pins are inserted into the limiting holes. This allows the first through hole and the second through hole to be quickly aligned. After insertion, the bolt can be directly rotated to pass through the first and second through holes. Then, a rubber pad is placed on the end of the bolt, and the nut is rotated. When both sides of the rubber pad are tightly against the lower pole body and the nut, the rotation of the nut is stopped. This achieves the goal of quickly aligning the first and second through holes through the cooperation of the limiting block and the limiting groove, and the fixing of the upper and lower pole bodies can be completed in a short time.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figure 1-5 In this embodiment, a novel series-connected composite pole includes a lower pole body 1 and an upper pole body 3. The upper pole body 1 and the lower pole body 3 are glass fiber reinforced polyurethane composite poles. The lower pole body 1 and the upper pole body 3 are attached together. The lower pole body 1 is provided with an installation structure 2. The installation structure 2 includes a limiting block 201 and a limiting post 202. The outer wall of the limiting block 201 is inserted into the limiting groove 203. The inner wall of the limiting block 201 is machined with a first through hole 205. Multiple limiting posts 202 are inserted into limiting holes 204. The limiting groove 203 is machined in the middle of the inner wall of the lower pole body 1.

[0020] Multiple limiting holes 204 are machined on the inner edge of the lower section rod 1. Bolts 4 are provided inside the first through hole 205 and the second through hole 7. The upper ends of the limiting block 201 and the limiting post 202 are fixedly connected to the upper section rod 3. The second through hole 7 is machined on both sides of the inner wall of the lower section rod 1. A rubber pad 5 is sleeved on the outer wall of the bolt 4. The two sides of the rubber pad 5 abut against the lower section rod 1 and the nut 6 respectively. The inner wall of the nut 6 is threadedly connected to the bolt 4.

[0021] Working principle:

[0022] When using the new series-connected composite poles:

[0023] The operator inserts the upper rod 3 into the lower rod 1 (both the upper and lower rods 1 are fiberglass-reinforced polyurethane composite poles), causing the limiting block 201 to enter the limiting groove 203 and the multiple limiting posts 202 to enter the limiting holes 204. This allows the first through hole 205 and the second through hole 7 to be quickly aligned, thus completing the connection between the upper rod 3 and the lower rod 1. After insertion, the bolt 4 can be directly rotated to pass through the first through hole 201 and the second through hole 7. Then, the rubber pad 5 is placed on the end of the bolt 4, and the nut 6 is rotated. When the two sides of the rubber pad 5 are respectively pressed against the lower rod 1 and the nut 6, the rotation of the nut 6 is stopped, thus fixing the upper rod 3 and the lower rod 1 together. Finally, glue can be injected at the connection between the bolt 4 and the lower rod 1 to improve the strength after connection.
