Description

Technical Field

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

[0002] A power transmission tower is a device used for overhead laying of cables and is widely used in the field of power transmission; power transmission towers are tall structures. In China, power transmission towers are mainly made of hot-rolled angle steel. With the continuous growth of power demand in China, the towers tend to be larger in size and have heavier loads, so there is a risk of being broken by strong winds including typhoons, and such accidents have occurred many times; generally, to improve the wind resistance of existing towers, the bases and bottoms of the towers are strengthened. However, from the analysis of accidents where existing power transmission towers are broken by strong winds such as typhoons, most of the positions where the towers are broken are in the middle of the towers, and there are almost no cases where the tower foundations are uprooted or damaged by typhoons; for this reason, Chinese Patent Grant Publication No.: CN113463968B discloses a lifting and folding wind-resistant power transmission tower, which can lower the crossbeam carrying fittings to the lower tower body of the power transmission tower, and at the same time can rotate and lower the upper tower body of the tower relative to the lower tower body to the side of the lower tower body, thereby reducing the center of gravity and height of the tower and achieving the effect of wind resistance; another example is Chinese Patent Grant Publication No.: CN217353795U, which discloses a lifting and folding wind-resistant power transmission tower. This structure fixes the foundation through the bottom fixed claw frame and the concrete base, then strengthens 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 the telescopic rod connects the top layer and the bottom layer, improving the stability of the middle layer, thereby improving the stability performance of the entire device; however, once the power transmission tower is put into use, it is necessary to support and tow the cables. If the crossbeam of the fittings and the tower body are lifted and lowered for wind resistance, the lifting load is large and it is easy to pull the cables, 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 transmission tower. The tower body and the tower base of the tower are integrally fixed, and the wind resistance of the tower can be enhanced through the lifting wind-resistant component.

[0004] The lifting wind-resistant component of the present invention includes: An arch decomposition unit, the arch decomposition unit includes an upper wind-resistant module and a lower wind-resistant module; both the upper wind-resistant module and the lower wind-resistant module include: A table board, and swing grooves are opened at the four corners of the table board; A wind-resistant force-bearing arm, the wind-resistant force-bearing arm includes a wind-resistant swing arm hinged to the inner side of the swing groove, a clamping seat is hinged to the end of the wind-resistant swing arm away from the table board, and a sliding cylinder is fixed on the clamping seat; the wind-resistant swing arms of the upper wind-resistant module are inclined upwards, and the wind-resistant swing arms of the lower wind-resistant module are inclined downwards; Damping decomposition unit, the damping decomposition unit includes hinge seat plates fixed to the top and bottom surfaces of the middle part of the wind-resistant swing arm, and first magnetorheological fluid dampers are hinged to the top and bottom of the hinge seat plates; the other ends of the first magnetorheological fluid dampers are hinged to end seats, and the end seats are respectively fixed to the top and bottom surfaces of the platen; a strong spring is sleeved outside the telescopic end of the first magnetorheological fluid damper, and both ends of the strong spring respectively abut between the end of the first magnetorheological fluid damper and the hinge seat plate; Wind-resistant lifting assembly, the wind-resistant lifting assembly includes a main telescopic rod fixedly opposed to the middle of two platens, and an oil cylinder is fixed between the outer cylinder and the inner column of the main telescopic rod; Lifting guiding unit, the lifting guiding unit includes wire seats fixed to the inner sides of the angle steels of the iron tower, and a wire body is fixed between the wire seats; the sliding cylinder is slidably installed on the wire body; upper and lower limit platforms are fixed on the wire body; the bottom of the sliding cylinder of the upper wind-resistant module abuts against the top of the upper limit platform, and the top of the sliding cylinder of the lower wind-resistant module abuts against the bottom of the lower limit platform; The arched decomposition unit is hoisted and fixed at the center of the iron tower.

[0005] When the lifting and wind-resistant component is in use, the arched decomposition unit is set in the wind protection area of the iron tower, the wind-resistant swing arms of the upper wind-resistant module are tilted upward, and the wind-resistant swing arms of the lower wind-resistant module are tilted downward; the sliding cylinder is pressed onto the angle steel of the iron tower. When the iron tower needs to be protected, the wind-resistant lifting component acts, the oil cylinder retracts, driving the outer cylinder and the inner column of the main telescopic rod to contract, thereby driving the two platen plates to approach each other; the sliding cylinder slides along the wire body; when the bottom of the sliding cylinder of the upper wind-resistant module is restricted by the upper limit platform and the top of the sliding cylinder of the lower wind-resistant module is restricted by the lower limit platform; at this time, the oil cylinder continues to retract, and a certain output current of the first magnetorheological fluid damper is set according to the wind speed. At this output current, when the wind-resistant swing arm continuously presses against the angle steel, during the pressing process, the inner shaft of the first magnetorheological fluid damper can overcome the damping force and travel one stroke, so as to ensure that the wind-resistant swing arm and the angle steel form a complete arched structure. Especially for the area of the iron tower that is narrow at the top and wide at the bottom, it can be fully adapted. That is, when the oil cylinder continuously retracts, the upper wind-resistant module or the lower wind-resistant module is pre-tightened in advance. At this time, the position of the outer cylinder or the inner column corresponding to this end is fixed. When the oil cylinder continues to retract, the fixed position end remains stationary or overcomes the damping force to perform a 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 of the upper wind-resistant module and the lower wind-resistant module and the angle steel form a local arched structure, and the overall anti-deformation of this area is carried out through the tension of the arch, and the damping force is adapted at both ends of the arched structure according to the wind speed; the deformation amount at the contact position is decomposed and consumed through the damping force; the anti-deformation ability 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 expand and contract; then, the oil cylinder extends and resets, and the inner shaft of the first magnetorheological fluid damper is extended and reset by the strong spring, avoiding that the first magnetorheological fluid damper cannot be extended after being pressed in position due to fluctuations; in addition, it is also convenient for the second precise locking of the wind-resistant swing arm during the clamping action of the oil cylinder.

[0006] Further, a plurality of outer telescopic rods are fixed outside the main telescopic rod on the two platen plates, and an oil pipe perforation is provided at the center of the inner column; through the oil pipe perforation, it is convenient for the oil supply pipe and the oil return pipe of the oil cylinder to enter and exit the outer cylinder.

[0007] Further, the hoisting member includes a hoisting frame fixed to the angle steel of the iron tower by flanges or welding, and the hoisting frame is fixed to the top surface of the platen plate by a plurality of hoisting wires; when installing the hoisting member, first fix the hoisting frame to the iron tower, and then hoist the hoisting frame and the platen plate by the hoisting wires. When hoisting, the hoisting space for the upper wind-resistant module and the lower wind-resistant module needs to be reserved.

[0008] Furthermore, the hoisting member includes a plurality of telescopic stay cables. One end of each telescopic stay cable is hinged to the angle steel of the iron tower through a hinge seat; the other end of each telescopic stay 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 platen; the hinge seat is fixed to the angle steel of the iron tower by a flange or welding; the telescopic stay cable includes screw barrels with opposite thread directions, and an adjusting screw is screwed inside each screw barrel; when installing the hoisting member, first integrally assemble the iron tower, the telescopic stay cables and the second magnetorheological fluid damper. After the assembly is completed, rotate the adjusting screw to tension and install the second magnetorheological fluid damper. When the upper wind resistance module and the lower wind resistance module need to be lifted and adjusted, adjust the damping force of the second magnetorheological fluid damper. When the upper wind resistance module and the lower wind resistance module are lifted and lowered, the second magnetorheological fluid damper can achieve anti-damping telescoping. After the lifting and adjusting are completed, the second magnetorheological fluid damper locks the position.

[0009] Furthermore, a semi-circular cavity tube is integrally formed between the upper limit platform and the lower limit platform. Tapered anchor holes are provided at one end of the upper limit platform and the lower limit platform close to each other; tapered anchor holes are provided at one end of the two wire seats away from each other; two wire bodies are provided. One end of each of the two wire bodies passes through the upper limit platform and the lower limit platform, and the other end passes through the wire seat respectively; after prestress is applied to both ends of the two wire bodies, the outer part of the wire body clamps the anchor head and is respectively embedded in the upper limit platform, the lower limit platform and the wire seat; after the installation of the anchor head is completed, unload the prestress; The upper limit platform and the lower limit platform can limit the upper wind resistance module and the lower wind resistance module. When installing the lifting and guiding unit, prestress is applied to the wire bodies through a prestress application device, and the position of the prestressed wire bodies is locked through the anchor heads. And because the wire bodies are prestressed in advance, the wire seats and the angle steel form a bow arm structure with micro-deformation, and the wire bodies form a bowstring structure. When local deformation occurs in the iron tower, the structure formed by the wire seats, the angle steel and the wire bodies can offset the shear force of the local deformation; in addition, the wire bodies can be used as guiding members for the lifting and lowering actions of the upper wind resistance module and the lower wind resistance module.

[0010] Furthermore, the outer diameter of the sliding cylinder is larger than the outer diameters of the upper limit platform and the lower limit platform; the inner diameter of the sliding cylinder is smaller than the outer diameters of the upper limit platform and the lower limit platform; the inner diameter of the sliding cylinder is 1.5 - 3 times the outer diameter of the wire body.

[0011] 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 iron tower; the wind speed transmitter monitors the wind speed in real time, and according to the wind speed and current correlation table preset in the controller, the controller obtains the current matching the wind speed, and then, the controller controls the current of the first magnetorheological fluid damper, regulates the rheological characteristics of the magnetorheological fluid through the magnetic field, obtains the corresponding damping force, and realizes the absorption and dissipation of the energy brought by the wind force.

[0012] Further, a winding motor is fixed on the steel wire seat; both ends of the steel wire body are wound and fixed on the winding motor; the hoisting member includes an I-shaped sliding sleeve slidably disposed outside the main telescopic rod, and a plurality of spring seats are fixed on the upper and lower portions of the sliding sleeve; the spring seats slide through guide rods, and the guide rods are fixed to the sliding sleeve; a spring body is disposed between the guide rods and the sliding sleeve and the spring seats; a plurality of telescopic arms are disposed on the sliding sleeve, and electromagnets are fixed to the ends of the telescopic arms; a plurality of cassette inclinometers are fixed to the iron tower from bottom to top; the electromagnets are attracted to the angle steel of the iron tower.

[0013] During operation, when the cassette inclinometer monitors that the deformation amount at a certain height of the tower body exceeds the set value, the controller gives a power-off signal to the electromagnet and synchronously triggers the action of the winding motor. The winding motor at the bottom pays out the wire, and the winding motor at the top winds up the wire until the arched decomposition unit travels to the set height. At this time, the electromagnet is powered on, and the electromagnet is attracted to the angle steel of the iron tower. The arched decomposition unit can be supported by the telescopic arms and the spring body; then, after the winding motor at the top pays out the wire to the set number of turns and locks, then, the winding motor at the bottom winds up the wire to realize the tensioning of the steel wire body, and reserve a stroke for the upper wind resistance module and the lower wind resistance module to approach each other; then, the arched decomposition unit operates to realize the wind resistance and anti-deformation at the corresponding position of the iron tower.

[0014] Further, there are four groups of the telescopic arms, which are fixed to the sliding sleeve in an X shape; the telescopic arms are disposed opposite to the inner wall of the angle steel of the iron tower.

[0015] An anti-wind power transmission tower includes one or more groups of lifting anti-wind components, and also includes an iron tower. The lifting anti-wind components are fixed to the middle and lower part, the middle part or the upper part of the tower body of the iron tower. Through the lifting anti-wind components, an arched support structure can be provided for the easily deformed position of the iron tower under the action of wind, and damping can be established at both ends of the I-shaped support structure; the wind shear force can be decomposed and unloaded.

[0016] Compared with the prior art, for the lifting wind-resistant component and the wind-resistant power transmission tower of the present invention, the tower adopts a fixed structure, which avoids the swinging and pulling of cables caused by the lifting of the tower, and can prevent the shear fracture of the lifting part of the tower; when it is monitored that the tower is affected by a certain level of wind force, the first magnetorheological fluid damper can output a matching resistance to achieve nearly rigid support between the angle steels of the tower body. When the angle steel is locally deformed under the shear force, an arch structure is formed in the deformed area through the upper wind-resistant module and the lower wind-resistant module to form a reaction force against the shear force, which can resist local deformation. At the same time, since the first magnetorheological fluid damper matches the wind force level and the upper wind-resistant module and the lower wind-resistant module provide nearly rigid support for the angle steel, when the tower is in the full output state of this wind force level, the toughness of the tower acts on the first magnetorheological fluid damper, allowing the first magnetorheological fluid damper to be slightly stretched under force, avoiding the end deformation at the contact position between the upper wind-resistant module and the lower wind-resistant module and the angle steel; the micro-stretching amount of the first magnetorheological fluid damper does not exceed half of the operating deformation amount of the tower, and the overall wind resistance of the tower is strong.

[0026] When the lifting and wind-resistant component is in use, the arched decomposition unit is set in the wind protection area of the iron tower, and the wind-resistant swing arm 2 of the upper wind-resistant module is tilted upward, and the wind-resistant swing arm 2 of the lower wind-resistant module is tilted downward; the sliding cylinder 4 is pressed against the angle steel 13 of the iron tower. When the iron tower needs to be protected, the wind-resistant lifting component acts, the oil cylinder 12 retracts, driving the outer cylinder 10 and the inner column 11 of the main telescopic rod 9 to contract, thereby driving the two platen plates 1 to approach each other; the sliding cylinder 4 slides along the steel wire body 15; when the bottom of the sliding cylinder 4 of the upper wind-resistant module is restricted by the upper limit platform 16, and the top of the sliding cylinder 4 of the lower wind-resistant module is restricted by the lower limit platform 17; at this time, the oil cylinder 12 continues to retract, and a certain output current of the first magnetorheological fluid damper 6 is set according to the wind speed. At this output current, when the wind-resistant swing arm 2 continuously presses against the angle steel 13, during the pressing process, the inner shaft of the first magnetorheological fluid damper 6 can overcome the damping force and travel a stroke, so as to ensure that the wind-resistant swing arm 2 and the angle steel 13 form a complete arched structure. Especially for the area of the iron tower that is narrow at the top and wide at the bottom, it can be fully adapted. That is, when the oil cylinder 12 continuously retracts, the upper wind-resistant module or the lower wind-resistant module is pre-tightened in advance. At this time, the position of the outer cylinder 10 or the inner column 11 corresponding to this end is fixed. When the oil cylinder 12 continues to retract, the fixed position end remains stationary, or overcomes the damping force to perform a micro-displacement. 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 2 of the upper wind-resistant module and the lower wind-resistant module and the angle steel 13 form a local arched structure, and the overall anti-deformation of this area is carried out through the tension of the arch, and the two ends of the arched structure adapt the damping force according to the wind speed; the deformation amount of the contact position is decomposed and consumed through the damping force; the anti-deformation ability 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 6 is released. At this time, the inner shaft of the first magnetorheological fluid damper 6 can freely expand and contract; then, the oil cylinder 12 extends and resets, and the inner shaft of the first magnetorheological fluid damper 6 is extended and reset through the strong spring 8, so as to prevent the first magnetorheological fluid damper 6 from being unable to extend after being pressed into the position due to fluctuations; in addition, it is also convenient for the second precise locking of the wind-resistant swing arm 2 during the clamping action of the oil cylinder 12.

[0027] A plurality of outer telescopic rods 18 are fixed outside the main telescopic rod 9 on the two platen plates 1, and an oil pipe through hole 19 is opened at the center of the inner column 11; through the oil pipe through hole 19, it is convenient for the supply oil pipe and the return oil pipe of the oil cylinder 12 to enter and exit the outer cylinder 10.

[0028] The hoisting member includes a hoisting frame fixed to the angle steel 13 of the iron tower by flange or welding. The hoisting frame is fixed to the top surface of the platen plate 1 by a plurality of hoisting steel wires 20; when installing the hoisting member, first fix the hoisting frame to the iron tower, and then hoist the hoisting frame and the platen plate 1 through the hoisting steel wires 20. When hoisting, the hoisting space for the upper wind-resistant module and the lower wind-resistant module needs to be reserved.

The upper limit platform 16 and the lower limit platform 17 can limit the upper and lower wind resistance modules. When installing the lifting and guiding unit, prestress is applied to the wire bodies 15 by a prestress application device, and the position of the prestressed wire bodies 15 is locked by the anchor heads 26.

[0034] During operation, when the cassette inclinometer monitors that the deformation amount at a certain height of the tower body exceeds the set value, the controller gives a power-off signal to the electromagnet 32 and synchronously triggers the action of the winding motor. The winding motor at the bottom pays out the wire, and the winding motor at the top takes in the wire until the arched decomposition unit moves to the set height.
