Description

Technical Field

[0001] This invention relates to the field of power transmission tower technology, specifically to a power transmission tower resistant to strong winds. Background Technology

[0002] Power transmission towers are structures used to support and maintain power transmission lines. Their function is to elevate power lines to ensure the stability and reliability of power supply. Power transmission towers are usually made of steel or aluminum alloy, which have good strength and stability, and are treated with anti-corrosion to extend their service life. However, power transmission towers are usually made of triangular steel. Although triangular steel can increase the structural stability of the assembly, the direction of wind is not fixed. When assembling and installing triangular steel, the direction of the corner ends cannot always be kept outward. The corner ends of the triangular steel are used to break the wind and reduce the impact of wind resistance on the overall structure. Summary of the Invention

[0003] The purpose of this invention is to provide a power transmission tower resistant to strong winds, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A strong wind resistant power tower includes four symmetrical fixed seats. Each fixed seat is provided with several sets of tower plates. A connecting seat is provided between two adjacent tower plates in the vertical direction. A horizontal tie rod is provided between two connecting seats on the same horizontal plane on the left and right sides. An oblique tie rod is provided between two connecting seats that are staggered vertically on the front and rear sides. A traction component is provided above each of the tower plates at the top. The traction assembly includes a reinforcing rod and a positioning pin connected to the end of the reinforcing rod. The bottom of the positioning pin is provided with a pull ring, and a steel wire rope is wound and fixed on the pull ring. The bottom of the steel wire rope is provided with a traction seat. The connector has slots at both the top and bottom ends, and arc plates on both sides of the connector. Several positioning holes are provided on the arc plates, and several through holes are symmetrically provided on the outer wall of the connector.

[0005] Furthermore, the fixing base is shaped like a frustum, the top of the fixing base is fixedly connected to the bottom of the bottom tower plate, and the bottom of the fixing base is buried in the ground.

[0006] In this invention, the frustum-shaped fixing base increases the contact area with the ground, increases the friction during installation, and is deeply embedded in the concrete of the ground, thereby increasing the stability of the tower foundation installation.

[0007] Specifically, the cross-section of the tower plate is triangular, and the corners of the tower plate are arranged outwards. The width of the outer wall of the tower plate is adapted to the width of the inner wall of the slot.

[0008] In this invention, the tower plate is made of triangular steel with the triangular corners distributed outwards, which helps to break up the incoming wind, reduce the impact of wind resistance, and increase the wind resistance of the tower plate.

[0009] It should be noted that the tower plate has symmetrical fixing holes at both ends. The fixing holes are matched with the diameter of the through holes. The through holes are equipped with fixing bolts, which pass through the through holes and fixing holes in sequence, and the ends of the fixing bolts are equipped with nuts.

[0010] In this invention, two sets of fixing holes are fitted at both ends of the tower plate. With the fixing bolts passing through the through holes and fixing holes, and with the cooperation of the nuts, the tower plate and the connecting seat can be stably assembled.

[0011] Furthermore, the cross section of the horizontal tie rod is triangular, and the horizontal tie rod and the first hinge seat are integrally formed. The first hinge seat is inserted and rotated with the arc plate. The corner ends of the horizontal tie rod are all arranged outward. The first hinge seat is provided with a connecting hole, the diameter of which is adapted to the diameter of the positioning hole. A fixing bolt is provided in the positioning hole. The fixing bolt passes through the positioning hole and exits from the connecting hole, and the end of the fixing bolt is connected to a nut.

[0013] It is worth noting that the cross-section of the diagonal tie rod is triangular, the diagonal tie rod and the second hinge seat are integrally formed, the second hinge seat is inserted and rotated with the arc plate, the corner ends of the diagonal tie rod are arranged outwards, the second hinge seat is provided with corresponding connection holes, the fixing bolt passes through the positioning hole and out of the connection hole, and the end of the fixing bolt is connected to the nut.

[0014] In this invention, multiple diagonal tie rods are combined and fixed with the two intersecting connecting seats on the front and rear sides, respectively, with the second hinge seat in cooperation. The fixing bolts pass through the positioning holes and connecting holes in sequence to realize the assembly and fixing of the diagonal tie rods and connecting seats, thereby increasing the structural stability between adjacent tower plates. Furthermore, the diagonal tie rods on the front and rear sides are arranged in parallel and intersecting directions to realize the staggered connection and fixing of the tower plates between the front and rear sides, thereby increasing the tensile strength.

[0015] Furthermore, the reinforcing rod and the socket are integrally formed, the width of the outer wall of the socket is adapted to the width of the inner wall of the slot, and a pin hole is also provided at the end of the reinforcing rod, and the positioning pin is inserted into the pin hole.

[0016] In this invention, the positioning pin is inserted into the pin hole, and the limiting plate at the top of the positioning pin restricts the position of the positioning pin on the reinforcing rod, thereby increasing the stability of the installation.

[0017] In addition, the pull ring is rotatably connected to the bottom of the positioning pin, the top of the wire rope is wrapped and locked with the pull ring and fixed with bolts, the bottom of the wire rope is fixed to the traction seat with bolts, and the traction seat is inserted into the ground with pins.

[0018] In this invention, the pull ring and the positioning pin cooperate to facilitate the top winding assembly of the wire rope. The wire rope extends to the ground, increasing the stability of the connection between the reinforcing rod and the ground. With the cooperation of the traction seat, the wire rope is fixed to the corresponding tower plate. The four sets of traction components correspond to the four sets of fixing seats and tower plates, which enhances the overall stability of the ground fixation and further increases the wind resistance.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves tower frame assembly by setting multiple connecting seats with arc plates, which connect two adjacent tower plates, and the arc plates on the connecting seats on the left and right sides are connected by horizontal tie rods to enhance connection stability, and the arc plates on the connecting seats on the front and rear sides are fixed by diagonal tie rods. With the cooperation of four sets of traction components and steel wire ropes, the stability of the tower assembly with the ground is further increased, and the overall wind resistance is increased.
