Description

Technical Field

[0001] The present invention specifically relates to a lifting wind-resistant component and a wind-resistant power tower, and belongs to the technical field of wind-resistant power towers. Background Art

[0002] The power tower is a device for overhead cables, which has been widely used in the field of power transmission. The power tower is a tall structure. my country's power tower is mainly made of hot-rolled angle steel. With the continuous growth of my country's electricity demand, the tower tends to be larger and the load is getting heavier. Therefore, there is a risk of being blown down by strong winds including typhoons, and such accidents have occurred many times. The existing towers are generally strengthened to improve their wind resistance by strengthening the base and bottom of the tower. However, from the analysis of the accidents of the existing power towers being blown down by strong winds such as typhoons, the position where the tower is blown down is mostly the middle of the tower, and there is almost no situation where the tower foundation is pulled up or damaged by the typhoon. For this reason, China Patent Authorization Announcement No.: CN113463968B discloses a lifting and folding wind-resistant power tower, which can lower the horizontal frame carrying hardware to the power station. The lower tower body of the power tower can be rotated and lowered relative to the lower tower body to the side of the lower tower body, thereby lowering the center of gravity and height of the tower to achieve a wind-resistant effect; for example, China Patent Authorization Announcement No.: CN217353795U discloses a lifting and folding wind-resistant power tower, which fixes the foundation through the bottom fixed claw frame and the concrete base, and then reinforces the stability of the top layer through the connection between the second sliding rod, the first connecting rod, the second connecting rod, the third connecting rod and the tower top plate, and finally connects the top layer and the bottom layer with the telescopic rod, so that the stability of the middle layer is improved, thereby improving the stability performance of the entire device; but once the power tower is put into use, it needs to support and pull the cables. If the cross frame and tower body of the hardware are lifted and lowered for wind resistance, the lifting load is large and the cables are easily pulled, and the support stability of the entire tower is poor. Summary of the Invention

[0003] To solve the above problems, the present invention proposes a lifting wind-resistant component and a wind-resistant power tower, the tower body and tower base of the tower are fixed in an integrated manner, and the wind-resistant ability of the tower can be enhanced by lifting the wind-resistant component.

[0004] The lifting and wind-resistant assembly of the present invention comprises:

[0005] The arch decomposition unit includes an upper wind-resistant module and a lower wind-resistant module; the upper wind-resistant module and the lower wind-resistant module each include:

[0006] A table top, wherein the four corners of the table top are provided with swing grooves;

[0007] The wind-resistant force-bearing arm includes a wind-resistant swing arm hinged to the inner side of the swing groove, the wind-resistant swing arm is hinged to a clamping seat at one end away from the table, and a slide is fixed on the clamping seat; the wind-resistant swing arm of the upper wind-resistant module is tilted upward, and the wind-resistant swing arm of the lower wind-resistant module is tilted downward;

[0008] A damping decomposition unit, comprising an articulated seat plate fixed to the top and bottom surfaces of the middle portion of the wind-resistant swing arm, wherein the top and bottom of the articulated seat plate are hingedly connected to a first magneto-rheological fluid damper; the other end of the first magneto-rheological fluid damper is hinged to an end seat, and the end seats are respectively fixed to the top and bottom surfaces of the table; a strong spring is sleeved on the outside of the telescopic end of the first magneto-rheological fluid damper, and the two ends of the strong spring are respectively abutted between the end of the first magneto-rheological fluid damper and the articulated seat plate;

[0009] A wind-resistant lifting assembly, comprising a main telescopic rod fixed between the two platform plates, with an oil cylinder fixed between the outer tube and the inner column of the main telescopic rod;

[0010] The lifting guide unit includes a steel wire seat fixed to the inner side of the angle steel of the iron tower, a steel wire body is fixed between the steel wire seats; the slide is slidably installed with the steel wire body; an upper limit platform and a lower limit platform are fixed on the steel wire body; the bottom of the slide of the upper wind-resistant module abuts against the top of the upper limit platform, and the top of the slide of the lower wind-resistant module abuts against the bottom of the lower limit platform;

[0011] The arched decomposition unit is hoisted and fixed to the center of the iron tower.

[0012] When the lifting wind-resistant assembly is in use, the arch decomposition unit is set to the wind-protected area of the tower, and the wind-resistant swing arm of the upper wind-resistant module is tilted upward, and the wind-resistant swing arm of the lower wind-resistant module is tilted downward; the slide is pressed onto the angle steel of the tower. When the tower needs to be protected, the wind-resistant lifting assembly is actuated, the oil cylinder retracts, and the outer tube and inner column of the main telescopic rod are driven to retract, thereby driving the two platforms closer to each other; the slide slides along the steel wire; when the bottom of the slide of the upper wind-resistant module is restricted by the upper limit platform, the top of the slide of the lower wind-resistant module is The oil cylinder continues to retract, and a certain output current of the first magnetorheological fluid damper is set according to the wind speed. Under the output current, when the wind-resistant swing arm continues to press the angle steel, during the pressing process, the inner shaft of the first magnetorheological fluid damper can overcome the damping force and travel a stroke, thereby ensuring that the wind-resistant swing arm and the angle steel form a complete arch structure, especially for the area where the tower is narrow at the top and wide at the bottom, it can fully adapt to the situation, that is, when the oil cylinder continues to retract, the upper wind-resistant module or the lower wind-resistant module is pre-completed. The pre-tightening is achieved. At this time, the position of the outer cylinder or inner column at the corresponding end is fixed. When the oil cylinder continues to retract, the fixed position end remains stationary, or overcomes the damping force to perform micro-displacement, and the upper wind-resistant module or the lower wind-resistant module in the active position quickly completes the following action to achieve rapid pre-tightening. At this time, the wind-resistant swing arms and angle steels of the upper wind-resistant module and the lower wind-resistant module form a local arch structure, and the overall deformation of the area is resisted by the tension of the arch, and the two ends of the arch structure adapt the damping force according to the wind speed; the contact position is achieved by the damping force The deformation of the setting is decomposed and consumed; the deformation resistance of the entire iron tower is enhanced. When the wind speed is lower than the set value within a certain period, the damping force of the first magnetorheological fluid damper is released. At this time, the inner shaft of the first magnetorheological fluid damper can freely extend and retract. Then, the oil cylinder extends and resets, and the inner shaft of the first magnetorheological fluid damper is extended and reset through a strong spring, so as to prevent the first magnetorheological fluid damper from remaining in the pressed position and unable to extend after being affected by fluctuations. In addition, it also facilitates the precise locking of the second wind-resistant swing arm during the oil cylinder clamping action.

[0013] Furthermore, the two platforms are fixed with multiple outer telescopic rods outside the main telescopic rod, and an oil pipe perforation is opened at the center of the inner column; the oil pipe perforation can facilitate the oil supply pipe and oil return pipe of the oil cylinder to enter and exit the outer cylinder.

[0014] Furthermore, the hoisting parts include a hoisting frame fixed to the angle steel of the iron tower by flange or welding, and the hoisting frame is fixed to the top surface of the table plate by multiple hoisting steel wires; when the hoisting parts are installed, the hoisting frame is first fixed to the iron tower, and then the hoisting frame and the table plate are hoisted by the hoisting steel wires. During hoisting, hoisting space for the upper wind-resistant module and the lower wind-resistant module needs to be reserved.

[0015] Furthermore, the hoisting component includes a plurality of telescopic inclined cables, one end of which is hinged to the angle steel of the iron tower through an articulated seat; the other end of the telescopic inclined cable is hinged to the second magnetorheological fluid damper; the telescopic end of the second magnetorheological fluid damper is fixed to the top surface of the table; the articulated seat is fixed to the angle steel of the iron tower through a flange or welding; the telescopic inclined cable includes a screw barrel with opposite thread directions, and an adjustment screw is screwed inside the screw barrel; when the hoisting component is installed, the iron tower, the telescopic inclined cable and the second magnetorheological fluid damper are first assembled into one body, and after the assembly is completed, the adjustment screw is rotated to tighten the second magnetorheological fluid damper and install it. When the upper wind-resistant module and the lower wind-resistant module need to be raised and lowered, the damping force of the second magnetorheological fluid damper is adjusted. When the upper wind-resistant module and the lower wind-resistant module are raised and lowered, the second magnetorheological fluid damper can achieve anti-damping extension and contraction. After the lifting and adjustment is completed, the second magnetorheological fluid damper is locked in position.

[0016] Furthermore, a semicircular cavity tube is integrally formed between the upper limit platform and the lower limit platform, and a conical anchor hole is provided at one end of the upper limit platform and the lower limit platform close to each other; a conical anchor hole is provided at one end of the two wire seats away from each other; two steel wire bodies are provided, one end of the two steel wire bodies passes through the upper limit platform and the lower limit platform, and the other end passes through the wire seats respectively; after prestressing is applied to both ends of the two steel wire bodies, the anchor heads are clamped on the outside of the steel wire bodies and are respectively embedded in the upper limit platform, the lower limit platform and the wire seats; after the anchor heads are installed, the prestressing is unloaded;

[0017] The upper limit platform and the lower limit platform can limit the upper wind-resistant module and the lower wind-resistant module. When the lifting guide unit is installed, prestress is applied to the steel wire body through the prestressing device, and the position of the prestressed steel wire body is locked by the anchor head. Since the steel wire body is prestressed in advance, the steel wire seat and the angle steel present a micro-deformed bow arm structure, and the steel wire body presents a bowstring structure. When the iron tower is locally deformed, the structure formed by the steel wire seat, the angle steel and the steel wire body can offset the shear force of the local deformation. In addition, the steel wire body can serve as a guide for the lifting and lowering actions of the upper wind-resistant module and the lower wind-resistant module.

[0018] Furthermore, the outer diameter of the slide is larger than the outer diameters of the upper and lower limit platforms; the inner diameter of the slide is smaller than the outer diameters of the upper and lower limit platforms; the inner diameter of the slide is 1.5-3 times the outer diameter of the steel wire body.

[0019] Furthermore, the first magnetorheological fluid damper and the oil cylinder are connected to a controller, and the controller is connected to a wind speed transmitter on the tower; the wind speed transmitter monitors the wind speed in real time, and according to a wind speed and current correlation table preset in the controller, the controller obtains a current that matches the wind speed. Then, the controller controls the current of the first magnetorheological fluid damper, regulates the rheological properties of the magnetorheological fluid through the magnetic field, obtains a corresponding damping force, and realizes the absorption and dissipation of energy brought by the wind.

[0020] Furthermore, a winding motor is fixed on the wire seat; both ends of the steel wire body are wound and fixed on the winding motor; the hoisting part includes an I-shaped sliding sleeve slidably arranged on the outside of the main telescopic rod, and the cylinder seat is fixed with multiple spring seats on the upper and lower parts of the sliding sleeve; the spring seat slides through the guide rod, and the guide rod is fixed to the sliding sleeve; the guide rod is provided with a spring body between the sliding sleeve and the spring seat; multiple telescopic arms are provided on the sliding sleeve, and electromagnets are fixed to the ends of the telescopic arms; multiple box-type inclinometers are fixed on the iron tower from bottom to top; the electromagnet is attracted to the angle steel of the iron tower.

[0021] During operation, when the box-type inclinometer detects that the deformation of the tower body at a certain height exceeds the set value, the controller sends a power-off signal to the electromagnet and synchronously triggers the winding motor to move. The winding motor at the bottom pays out the wire, and the winding motor at the top reels in the wire until the arch decomposition unit reaches the set height. At this time, the electromagnet is energized and the electromagnet is attracted to the angle steel of the tower. The arch decomposition unit can be supported by the telescopic arm and the spring body. Then, the winding motor at the top pays out the wire to the set number of turns and then locks it. Then, the winding motor at the bottom reels in the wire to tighten the steel wire and reserve a stroke for the upper wind-resistant module and the lower wind-resistant module to approach each other. Then, the arch decomposition unit moves to achieve wind resistance and deformation resistance at the corresponding position of the tower.

[0022] Furthermore, the telescopic arms are provided in four groups and are fixed on the sliding sleeve in an X shape; the telescopic arms are provided facing the inner wall of the angle steel of the iron tower.

[0023] A wind-resistant power tower includes one or more lifting and wind-resistant components and an iron tower. The lifting and wind-resistant components are fixed to the lower middle part, the middle part or the upper part of the tower body. The lifting and wind-resistant components can provide an arched support structure for the parts of the iron tower that are easily deformed by wind, and establish damping at the two end points of the I-shaped support structure; the wind shear force can be decomposed and unloaded.

[0024] Compared with the prior art, the lifting and wind-resistant component and wind-resistant power tower of the present invention adopt a fixed structure for the tower, which avoids the cable swinging and being entangled due to the lifting of the tower, and can avoid the lifting part of the tower being sheared and broken; when it is monitored that the tower is subjected to a certain level of wind force, the first magnetorheological fluid damper can output a matching resistance to achieve a nearly rigid support between the angle steels of the tower body; when the angle steel is locally deformed by the shear force, an arch structure is formed in the deformation area by the upper wind-resistant module and the lower wind-resistant module, forming a reverse force to the shear force, which can resist local deformation; at the same time, since the first magnetorheological fluid damper is matched with the wind force level, the upper wind-resistant module and the lower wind-resistant module are in a nearly rigid support for the angle steel; when the wind force level is fully output, the toughness of the tower acts on the first magnetorheological fluid damper, allowing the first magnetorheological fluid damper to be slightly stretched and contracted under force, thereby avoiding endpoint deformation at the position where the upper wind-resistant module and the lower wind-resistant module contact the angle steel; the micro-stretching amount of the first magnetorheological fluid damper under force does not exceed one-half of the deformation amount of the tower during operation, and the tower has a strong overall wind resistance.
