Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbine tower protection technology, and in particular to a wind turbine tower protection device that can be disassembled at the edge. Background Technology
[0002] As the core supporting structure of wind turbine generators, the reliability of the wind turbine tower directly affects the operational safety and lifespan of the unit. In practical applications, the tower is usually assembled from multiple sections, and the protective performance of the joints between these sections is crucial. While existing technologies use anti-corrosion coatings to waterproof the joints, these coatings are susceptible to cracking, peeling, or failure due to long-term ultraviolet radiation, temperature variations, and rainwater erosion. This exposes the metal substrate at the joints, exacerbating electrochemical corrosion. Furthermore, traditional sealing measures are insufficient to completely prevent insects and small reptiles from entering the tower through gaps, potentially damaging internal equipment cables, lubrication systems, and other components.
[0003] Furthermore, with the widespread deployment of wind power projects in outdoor and mountainous areas, towers face safety risks from human or wild animal climbing. Existing tower surfaces lack effective anti-climbing technologies, failing to effectively protect against structural damage and equipment malfunctions caused by unauthorized personnel approaching the equipment on top of the tower or animals climbing.
[0004] In response to the problems of joint protection (corrosion prevention and insect prevention) and anti-climbing safety protection in the above-mentioned multi-section assembled wind turbine towers, there is an urgent need to design an integrated solution that combines long-term sealing protection and active anti-climbing function to improve the environmental adaptability and operational safety of the tower. Utility Model Content
[0005] The purpose of this utility model is to provide a wind turbine tower protection device that is easy to disassemble, while achieving sealing protection and anti-climbing effects at the connection of tower pipe sections.
[0006] In accordance with the above objectives, this utility model provides a wind turbine tower protection device that is easy to disassemble, comprising two mutually cooperating protective plates. The two protective plates are fixedly spliced on the outside of the connection between adjacent tower pipe sections. Semi-circular sealing rings are provided on the upper and lower sides of the two protective plates. An installation ring is provided on the outer side of the protective plate between the two sealing rings. Multiple outwardly rotatable conical plates are provided on the installation ring along the circumferential direction.
[0007] Furthermore, the mounting ring is provided with a transmission assembly for driving the cone plate to rotate. The transmission assembly includes a transmission screw and a linkage unit. The transmission screw is rotatably mounted on the mounting ring and is parallel to the axis of the protective plate. A lifting plate that cooperates with the middle position of the transmission screw is slidably mounted on the outer side of the protective plate along its axial direction. The lifting plate drives the cone plate to flip through the linkage unit.
[0008] Furthermore, the linkage unit includes multiple racks corresponding to the cone plate, the racks extend into the interior of the mounting ring and are slidably connected thereto, the interior of the mounting ring is provided with a return spring that abuts against the bottom end of the rack, and the inner end of the cone plate is fixedly connected with a gear that meshes with the rack.
[0009] Furthermore, limit rods are symmetrically fixedly installed on both sides of the transmission screw on the mounting ring, and pressure plates are provided on the outer side of the sealing ring. The pressure plates are slidably installed on the limit rods, and the pressure plates are connected to the end of the transmission screw for transmission.
[0010] Furthermore, the outer surface of the sealing ring has a conical structure, and protrusions are fixedly connected at equal intervals along the circumferential direction on the outer surface of the sealing ring.
[0011] Furthermore, both sets of protective plates are provided with connecting plates at the joint, and the connecting plates of the two sets of protective plates are connected by bolts.
[0012] Furthermore, the inner side of the protective plate is provided with a sealing gasket.
[0013] Furthermore, a handle is provided on the outer side of the lifting plate.
[0014] Furthermore, a locking rod is installed through the lifting plate, and threaded holes that mate with the locking rod are symmetrically opened on the outer side of the protective plate near the mounting ring.
[0015] Furthermore, the threads at both ends of the transmission screw rotate in opposite directions.
[0016] The technical solution of this utility model uses two protective plates spliced and fixed to the outside of the tower pipe section connection. With the semi-circular sealing rings on the upper and lower sides, it can form a full-enclosed sealing protection for the splicing gap. Compared with traditional anti-corrosion coatings, it can effectively resist the effects of rainwater erosion, ultraviolet aging and temperature difference deformation, and prevent the exposed metal substrate at the joint from rusting. At the same time, it can prevent mosquitoes and small reptiles from entering the tower through the gap. The outer side is installed with a circumferentially set outward flip-out conical plate to form a physical barrier against climbing around the tower. The sharp structure formed after the conical plate flips outward can effectively prevent people or animals from climbing, improve the safety of tower operation, and the overall structure design is easy to disassemble, which is conducive to quick disassembly and assembly during later maintenance and repair. It has the dual functions of sealing protection and active anti-climbing. Attached Figure Description

[0027] Example 1
[0028] like Figures 1-5 As shown, this utility model provides a wind turbine tower protection device that is easy to disassemble, including two mutually cooperating protective plates 1. Each of the two sets of protective plates 1 is provided with a connecting plate 8 at the splicing point. The connecting plates 8 of the two sets of protective plates 1 are connected by bolts. The two protective plates 1 are fixedly spliced on the outside of the connection point of adjacent tower pipe sections through the fixed connection of the connecting plates 8.
[0029] Both protective plates 1 are provided with semi-circular sealing rings 2 on the upper and lower sides. The outer side of the sealing ring 2 is a conical structure. In order to enhance the sealing effect, protrusions 15 are fixedly connected at equal intervals along the circumference on the outer side of the sealing ring 2. Correspondingly, a pressure plate 5 is provided on the outer side of the sealing ring 2 for pressing the protrusions 15 by sliding. The two pressure plates 5 that are spliced together can be connected into a ring shape by screws to enhance the pressing effect on the protrusions 15.
[0030] An installation ring 3 is provided on the outer side of the protective plate 1 between two sealing rings 2. Multiple outwardly rotatable cone plates 6 are provided on the circumferentially arranged on the installation ring 3. A transmission assembly for driving the cone plates 6 to rotate is provided on the installation ring 3. The transmission assembly includes a transmission screw 9 and a linkage unit. The transmission screw 9 is rotatably mounted on the installation ring 3 and is parallel to the axis of the protective plate 1. A lifting plate 10 that cooperates with the middle position of the transmission screw 9 is slidably installed on the outer side of the protective plate 1 along its axial direction. A handle is provided on the outer side of the lifting plate 10. By sliding the lifting plate 10 up and down, the transmission screw 9 can be rotated, and the lifting plate 10 drives the cone plates 6 to rotate through the linkage unit.
[0031] The linkage unit includes multiple racks 13 corresponding to the cone plate 6. The racks 13 extend into the interior of the mounting ring 3 and are slidably connected thereto. The interior of the mounting ring 3 is provided with a return spring that abuts against the bottom end of the rack 13, so that the rack 13 has the ability to return to its original position when it is not subjected to the pressure of the lifting plate 10. The inner end of the cone plate 6 is fixedly connected with a gear 14 that meshes with the rack 13. Accordingly, in order to prevent the rack 13 from sliding out of the mounting frame, a corresponding limiting structure should be provided.
[0032] To ensure the pressure of the pressure plate 5 on the sealing ring 2 and the stability of the sliding, limit rods 4 are symmetrically fixed on both sides of the transmission screw 9 on the mounting ring 3. The pressure plate 5 is slidably mounted on the limit rods 4. The pressure plate 5 is connected to the end of the transmission screw. The threads at the two ends of the transmission screw turn in opposite directions. When the transmission screw rotates, the pressure plates 5 at both ends slide towards one side of the mounting ring 3 at the same time, thereby squeezing the sealing ring through the protrusion 15 on the sealing ring to enhance the sealing effect.
[0033] The inner side of the protective plate 1 is equipped with a sealing gasket to further enhance the sealing effect, prevent rainwater and dust from entering, protect the safety of the internal equipment, and at the same time prevent the tower body 7 from being invaded by external crawling insects during use, thus improving the protective performance.
[0034] In order to fix the rotating shaft of the cone plate 6, a locking rod 11 is installed through the lifting plate 10. The outer side of the protective plate 1 is symmetrically provided with threaded holes 12 that cooperate with the locking rod 11 near the mounting ring 3. When the lifting plate 10 presses the rack 13 to drive the cone plate 6 to rotate, the locking rod 11 is turned to connect with the threaded hole 12 on the outer side of the protective plate 1, thus keeping the cone plate 6 in the open state.
[0035] During installation: Place two protective plates 1 at the joint of the tower tube section and splice them together. Fix the two sets of connecting plates 8 with bolts. The sealing gasket between the two protective plates 1 can achieve a seal. Then, push the lifting plate 10 downward with the handle. The lifting plate 10 drives the transmission screw 9 to rotate through the screw nut pair. The transmission screw 9 then drives the two pressure plates 5 to move inward through the screw nut pair. During the movement, the pressure plates 5 squeeze the protrusion 15 on the outside of the sealing ring 2, squeezing the protrusion 15 against the outer wall of the tower body 7. This makes the sealing ring 2 fit tightly against the outer wall of the tower body 7, thereby achieving a tight seal at the assembly joint of the tower body 7. This prevents rainwater and dust from entering, protects the safety of the internal equipment, and prevents external crawling insects from entering the assembly joint of the tower body 7 during use, thus improving the protective performance.
[0036] Furthermore, during the downward movement of the lifting plate 10, multiple racks 13 can move downward synchronously, causing the racks 13 to rotate through meshing, thus flipping the cone plates 6 outward and preventing human or animal climbing, thereby further improving the protective performance of the tower body 7. After the lifting plate 10 is pushed downward, the locking rod 11 is screwed into the threaded hole 12 on the protective plate 1 to fix the lifting plate 10.
[0037] In practical use, this device can be installed in multiple sets according to the joints of multiple tower sections, and the number of sets can be increased or decreased as appropriate according to the actual situation.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
