Description

Technical Field

[0001] The utility model relates to the technical field of power transmission iron towers, in particular to a wind and sand prevention device for power transmission iron towers. Background Art

[0002] Transmission towers serve as the support points for overhead lines. A single-circuit transmission tower is a single-circuit tower, while a double-circuit tower is a double-circuit tower. Transmission towers are tall structures that are highly sensitive to tilt and deformation and require high tolerance for uneven ground settlement. Common foundation structures for transmission towers include independent foundations, expanded foundations, and pile foundations. Transmission towers are primarily steel structures, and after a certain period of service, they require fixed support.

[0003] For example, a transmission tower reinforcement device with publication number CN219061008U has a technical solution comprising: a main body and a fixed column, a fixed column being provided in the middle of the main body, a reduction motor being installed in the middle of the top of the fixed column, a rotating shaft being installed in the middle of the fixed column where the output shaft of the reduction motor is located, a moving column being sleeved in the middle of the outer surface of the fixed column, a positioning seat being installed in the fixed column on one side of the moving column, a fixing rod being sleeved in the middle of the positioning seat, a gear B being installed on the side of the fixed rod close to the rotating shaft, a gear A being installed on the outer surface of the rotating shaft on the side of gear B, and gear A being meshed with gear B. A transmission tower reinforcement device solves the problem that most existing transmission tower reinforcement mechanisms have limited overall reinforcement effects on transmission towers, have poor reinforcement effects, and have poor effects on improving the supporting performance of transmission towers, thereby improving the overall support effect of transmission towers and thus increasing the service life of transmission towers.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that although the above device can improve the overall support effect of the transmission tower to a certain extent, in actual use, the transmission tower is exposed to the outside all year round. When encountering windy and sandy weather, it is easy to erode the surface of the supporting steel, thereby causing the rigidity of the steel to decrease. The above device lacks effective wind and sand protection capabilities, and is likely to affect the service life of the supporting steel to a certain extent when used.

[0005] Therefore, in order to solve the above problems, a wind and sand protection device for a transmission tower is proposed. Utility Model Content

[0006] The technical problem to be solved by the present invention is that the existing technology has the disadvantage of lacking effective wind and sand protection capability. For this reason, we propose a wind and sand protection device for a transmission tower.

[0007] The technical solution adopted by the utility model to solve the technical problem is: a wind and sand protection device for a transmission tower, comprising a tower body; surfaces around the tower body are movably connected with plates, the surfaces of the plates are fixedly installed with a frame, both sides of the frame are provided with through holes, the inner sides of the through holes are movably installed with a rotating rod, the inner side of the rotating rod is fixedly installed with a covering plate, and one end of the rotating rod is fixedly installed with a limit plate.

[0008] Preferably, threaded holes are provided on the surfaces of the plate and the tower body, and fixing bolts are installed on the inner threads of the threaded holes.

[0009] Preferably, an outer control plate is fixedly mounted on the other end of the rotating rod, and a control rope is movably connected to the surface of the outer control plate.

[0010] Preferably, a supporting rope is fixedly installed on the surface of the control rope, and a tightening wheel is fixedly connected to the bottom end of the control rope.

[0011] Preferably, a driven wheel is fixedly mounted on the outer side of the tightening wheel, and the inner end of the tightening wheel is fixedly connected to the frame.

[0012] Preferably, the inner side of the driven wheel is meshedly connected to the driving wheel, the inner side of the driving wheel is fixedly connected to the driving motor, and the inner end of the driving motor is fixedly connected to the frame.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model facilitates the installation of the overall wind and sand prevention device on the periphery of the tower body through the arrangement of the sticking plates, and provides a space for the installation and rotation of the covering plates through the arrangement of the frame. The covering plates installed inside the frame are held up by the rotating rods on both sides and will not fall off easily. Moreover, due to the existence of the rotating rods, the covering plates can rotate freely. When the overall device is in use, under normal weather conditions, the covering plates are in an open state and will not affect the flow of natural wind. When windy and sandy weather comes, the control rope can be pulled downward by the tightening wheel. Under the pressure of the supporting rope, the overall covering plates are rotated downward, so that the space between the covering plates is covered, thereby forming a sealed state on the surface of the tower body. The wind and sand can only invade the covering plates but not the tower body, thereby achieving the effect of preventing the tower body from wind and sand.

[0015] 2. The utility model facilitates enhancing the installation stability between the overall wind and sand protection device and the tower body through the provision of threaded holes and fixing bolts. Through the provision of the external control plate, it is convenient for the control rope and the supporting rope to control the covering plate, so that it can be freely flipped. Through the provision of the tightening wheel, it is convenient for the user to drive one end of the control rope downward. A counterweight block is attached below the other end of the control rope, which can generate a downward falling force on the other end of the control rope, so that the covering plate can naturally return to the open state. Through the provision of the driven wheel and the driving wheel, it is convenient to transmit the rotational force of the driving motor. Through the provision of the driving motor, it is convenient to provide tightening power for the tightening wheel. BRIEF DESCRIPTION OF THE DRAWINGS
