Description

A type of fracture-resistant composite reinforced concrete pole Technical Field

[0001] This utility model relates to the technical field of transmission towers, specifically to a fracture-resistant composite reinforced concrete pole. Background Technology

[0002] Electricity poles are the most basic infrastructure for power transmission. Traditionally, electricity poles were made of wood. However, due to their short lifespan, insufficient strength, and the increasing scarcity of materials, they have been gradually replaced by concrete and iron poles. Concrete poles are mainly formed by concrete and a steel reinforcement frame.

[0003] According to Chinese Patent Publication No. CN206616923U, a concrete utility pole is disclosed, comprising a pole body, reinforcing bars, a steel ring, a support slot, an inner cavity, a base plate, a grounding connector, an installation pit, and a support column. The reinforcing bars and steel ring are interwoven and formed by concrete molding to create a pole body with an inner cavity. The cross-section of the pole body is an isosceles trapezoid, and a grounding connector is fixedly provided on the upper side of the pole body.

[0004] In the above scheme, by burying the main body of the pole underground and using support columns to increase the support strength, the following disadvantages occur: In actual use, the pole is easily affected by wind and sways to a certain extent. Relying solely on the bottom installation mechanism, it is difficult to ensure that the pole does not tilt in the long term. Summary of the Invention

[0005] The purpose of this invention is to provide a fracture-resistant composite reinforced concrete pole to solve the problem that poles are easily affected by wind and sway to a certain extent during actual use, and it is difficult to ensure that the poles do not tilt in the long term by relying solely on the bottom installation mechanism.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a fracture-resistant composite reinforced concrete pole, comprising a pole body, the pole body being detachably mounted on a cement pier, a balancing steel cable fixed to the inner top surface of the pole body, a balancing block fixed to one end of the balancing steel cable, several counterweights fixed to the outer wall of the balancing steel cable, a buffer steel cable fixed to the bottom end of the balancing block, the buffer steel cable being eight centimeters long, the maximum diameter of the pole body being thirty centimeters, a first universal joint rotatably connected to one end of the buffer steel cable, a conical groove being formed on the top surface of the cement pier, a second universal joint rotatably connected to the inner bottom surface of the conical groove, two connecting plates being provided inside the conical groove, several fixing sleeves and several insert rods being fixed to the two adjacent sides of the two connecting plates respectively, the insert rods being slidably inserted into the interior of the fixing sleeves, a tension spring being fixed between one end of the insert rod and the fixing sleeve, and the first universal joint and the second universal joint being rotatably connected to the two distant sides of the two connecting plates respectively.

[0007] Preferably, the pole body is provided with a concrete layer and a graphene fiber frame from the outside to the inside, and the concrete layer is cast on the graphene fiber frame.

[0008] Preferably, the pole body is a tapered structure, and the pole body includes an upper pole section, at least one middle pole section, and a lower pole section from top to bottom. The upper pole section is connected to the middle pole section, the middle pole section is connected to each other, and the middle pole section is connected to the lower pole section using flanges.

[0009] Preferably, threaded rods are embedded in the four corners of the top surface of the cement block, and an installation base is fixed to the outer wall of the lower section of the pole. The four corners of the top surface of the installation base are provided with installation holes. One end of the threaded rod passes through the installation hole and extends to the top surface of the installation base. Two nuts are threaded to the outer wall of the top end of the threaded rod.

[0010] Preferably, a first limiting ring is fixed inside each of the plurality of fixed sleeves, and a second limiting ring is fixed on the outer wall of each of the plurality of insert rods.

[0011] Preferably, a plate is fixed to the bottom end of the middle section of the pole.

[0012] Compared with existing technologies, a fracture-resistant composite reinforced concrete pole employing the above-mentioned technical solution has the following beneficial effects:

[0013] 1. During use, by setting a balance block inside the pole body and connecting a buffer mechanism to the bottom of the balance block, the pole body is relieved from swaying by wind, and the balance block is also effectively prevented from colliding with the inside of the pole body, thereby reducing the risk of pole body breakage and tipping.

[0014] Second, in use, by replacing the traditional steel pipe structure with a graphene fiber frame, the overall weight of the pole body is reduced while the overall strength of the pole body is improved. In use, the pole body is composed of an upper section, a middle section, and a lower section, which facilitates the transportation of the pole body and increases the overall compressive and torsional resistance of the pole body.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] As shown in Figures 1-5, a fracture-resistant composite reinforced concrete pole includes a pole body 1, which is detachably mounted on a cement pier 2. A balancing steel cable 3 is fixed to the top surface inside the pole body 1. A balancing block 4 is fixed to one end of the balancing steel cable 3. Several counterweights 5 are fixed to the outer wall of the balancing steel cable 3. A buffer steel cable 6 is fixed to the bottom end of the balancing block 4. The buffer steel cable 6 is eight centimeters long. The maximum diameter of the pole body 1 is thirty centimeters. One end of the buffer steel cable 6 is rotatably connected to a first universal joint 8. The first universal joint 8 is an existing structure and will not be described in detail here. The top surface of the mud mound 2 is provided with a conical groove 7. The bottom surface of the conical groove 7 is rotatably connected to a second universal joint 9. The second universal joint 9 is an existing structure and will not be described in detail here. The inside of the conical groove 7 is provided with two connecting plates 10. Several fixed sleeves 11 and several insert rods 12 are fixed on the two sides of the two connecting plates 10 that are close to each other. The insert rods 12 are slidably inserted into the inside of the fixed sleeves 11. A tension spring 13 is fixed between one end of the insert rod 12 and the fixed sleeve 11. The first universal joint 8 and the second universal joint 9 are rotatably connected to the two sides of the two connecting plates 10 that are far apart from each other.

[0023] In use, a balance block 4, pulled by a balance steel cable 3, is installed inside the pole body 1, and multiple sets of counterweights 5 are installed to balance the weight of each section of the steel cable 3. When the pole body 1 is affected by wind and sways, the balance block 4 and the counterweights 5 are subjected to the force at the top of the pole body 1 and oscillate in a circular motion inside the pole body 1, thus damping the sway of the pole body 1. At the same time, a buffer steel cable 6 with a length of eight centimeters is installed. When the balance block 4 oscillates inside the pole body 1, and the angle between the balance steel cable 3 and the vertical line of the pole body 1 is greater than fifteen degrees, the buffer steel cable 6 becomes taut and pulls the connecting plate 10, causing the insertion rod 12 to pull the tension spring 13. At this time, the tension spring 13 generates a reverse pulling force, which dampens the sway of the balance block 4, preventing the balance block 4 from hitting the inner wall of the pole body 1 and preventing damage to the pole body 1. By setting a balance block 4 inside the pole body 1 and connecting a buffer mechanism to the bottom surface of the balance block 4, the pole body 1 is relieved from swaying by wind, and the balance block 4 is also effectively prevented from colliding with the inside of the pole body 1, thereby reducing the risk of breakage and tipping of the pole body 1.

[0024] As shown in Figures 2-5, the pole body 1 consists of a concrete layer 1001 and a graphene fiber frame 1002 arranged sequentially from the outside to the inside. The concrete layer 1001 is poured on the graphene fiber frame 1002. The pole body 1 has an overall conical structure. From top to bottom, the pole body 1 includes an upper pole section 101, at least one middle pole section 102, and a lower pole section 103. The upper pole section 101 is connected to the middle pole section 102, the middle pole section 102 is connected to each other, and the middle pole section 102 is connected to the lower pole section 103 using flange connections. Next, threaded rods 14 are embedded in the four corners of the top surface of the cement block 2. The outer wall of the lower section pole 103 is fixed with a mounting base 15. The four corners of the top surface of the mounting base 15 are provided with mounting holes 16. One end of the threaded rod 14 passes through the mounting hole 16 and extends to the top surface of the mounting base 15. Two nuts are threaded to the outer wall of the top end of the threaded rod 14. The inside of several fixing sleeves 11 is fixed with a first limiting ring 17. The outer wall of several insert rods 12 is fixed with a second limiting ring 18. The bottom end of the middle section pole 102 is fixed with an insert plate 19.

[0025] In use, by replacing the traditional steel pipe structure with a graphene fiber frame 1002, the overall weight of the pole body 1 is reduced while its overall strength is improved. The pole body 1 is composed of an upper section 101, a middle section 102, and a lower section 103, which facilitates transportation and increases the overall compressive and torsional resistance of the pole body 1. The mounting base 15 uses a threaded rod 14 and a nut to install it onto the concrete pier 2, ensuring the installation strength of the pole body 1. The first limiting ring 17 and the second limiting ring 18 can limit the insertion rod 12 at its maximum stroke, preventing it from detaching from the fixing sleeve 11. When the middle section 102 and the lower section 103 are installed, the insertion plate 19 is precisely inserted into the middle section 102 and the lower section 103, thereby increasing the strength of the pole body 1's installation structure.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
