Technical Field

[0001] The invention relates to the technical field of wind turbine generator sets, and in particular to a grounding tripping protection device for a wind turbine terminal tower drop insurance. Background Art

[0002] The terminal tower drop fuses of wind turbine generator sets that were put into operation earlier mostly adopt ordinary wind-proof design. In addition, due to their long years of operation, their wind-proof performance has declined and they are prone to fall off in windy weather. At the same time, due to design and selection issues, the drop fuse fuse tube is relatively long, and it is easy for the fuse tube to touch the tower cross-arm angle steel during free rotation, causing the collector line to ground and trip. Summary of the Invention

[0003] The present invention provides a grounding tripping protection device for a wind turbine terminal tower drop insurance, aiming to solve the problems in the prior art.

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] A device for preventing ground tripping when a wind turbine terminal tower falls includes a baffle and two fixing mechanisms. The two fixing mechanisms are relatively distributed and are respectively used for detachable connection with the wind turbine terminal tower; the baffle is distributed between the two fixing mechanisms, and its two ends are respectively connected to the two fixing mechanisms.

[0006] The beneficial effects of the present invention are as follows: during assembly, the baffle is connected to the wind turbine terminal tower using two fixing mechanisms, and the baffle blocks the fuse and the wind turbine terminal tower, thereby avoiding short circuits and being safer and more reliable.

[0007] The present invention has a simple structure and a reasonable design. The protection device achieves grounding protection by creating a sufficient insulation distance and insulating medium with the tower crossarm in a suspended state after the drop insurance is disconnected. At the same time, the device is very easy to assemble, which can meet the actual situation of easy installation on site, saving time and effort.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, each of the fixing mechanisms includes a fixing bracket and a clamping plate assembly, wherein the fixing bracket is fixedly connected to the end of the baffle; the clamping plate assembly is connected to one end of the fixing bracket, which is located on one side of the baffle and is used to clamp the L-shaped steel on the wind turbine terminal tower.

[0010] The beneficial effects of adopting the above further solution are simple structure and reasonable design. The clamping components connected to the two fixed brackets are used to clamp the L-shaped steel on the wind turbine terminal tower respectively, thereby realizing rapid assembly and disassembly of the baffle, facilitating on-site operations, saving time and effort.

[0011] Furthermore, the clamping plate assembly includes an upper clamping plate and a lower clamping plate, one end of the upper clamping plate is fixedly connected to the fixed bracket and forms a gap between the upper clamping plate and the fixed bracket for clamping one end of the L-shaped steel on the wind turbine terminal tower; the lower clamping plate is distributed below the other end of the upper clamping plate, and is movably connected to the other end of the upper clamping plate through an operating assembly, and is used to clamp the other end of the L-shaped steel on the wind turbine terminal tower.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that the structure is simple and the design is reasonable. The gap formed between the upper splint and the fixed bracket is used to clamp one end of the L-shaped steel, and then the lower splint is used to cooperate with the other end of the upper splint to clamp the other end of the L-shaped steel, thereby realizing rapid assembly and disassembly of the baffle, facilitating on-site operations, saving time and effort.

[0013] Furthermore, the upper splint is a Z-shaped plate structure.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that the structure is simple, and it is more reasonable to use a Z-shaped plate for the upper splint, which can not only realize rapid assembly with other components, but also cooperate with the fixed bracket and the lower splint to clamp the L-shaped steel, thereby realizing rapid assembly of the baffle, easy disassembly and assembly, convenient on-site operation, saving time and effort.

[0015] Furthermore, the lower clamping plate is a flat plate structure, which is parallel to the other end of the upper clamping plate.

[0016] The beneficial effects of adopting the above further solution are simple structure, reasonable shape design of the lower clamping plate, easy to cooperate with the upper clamping plate to clamp the other end of the L-shaped steel, and easy assembly.

[0017] Furthermore, the operating component includes a pull rod and a spring, the pull rod is perpendicular to the other end of the upper splint, it passes through the other end of the upper splint, and the two ends of the pull rod are respectively coaxially fixed with limit plates; the lower splint is sleeved on the lower end of the pull rod, and can rotate around the pull rod; the lower splint is located between the other end of the upper splint and the limit plate located at the lower end of the pull rod, and is fitted with the corresponding limit plate; the spring is coaxially movably sleeved on the pull rod, it is located above the other end of the upper splint, and the two ends of the spring are respectively abutted against the other end of the upper splint and the limit plate located at the upper end of the pull rod. Under the elastic force of the spring, the pull rod can move and drive the lower splint to move to clamp the other end of the L-shaped steel on the wind turbine terminal tower with the other end of the upper splint.

[0018] The beneficial effect of adopting the above further solution is that during assembly, the lower clamping plate is manually rotated to make room for the L-shaped steel to be assembled; then one end of the L-shaped steel is inserted into the gap between the fixed bracket and one end of the upper clamping plate, and then the lower clamping plate is rotated so that it and the other end of the upper clamping plate clamp the other end of the L-shaped steel, which is convenient for assembly. At this time, the elastic force of the spring ensures that the lower clamping plate always clamps the L-shaped steel;

[0019] When disassembling, pull down the pull rod to release the lower splint from the L-shaped steel, and then rotate the lower splint to make room for disassembling the L-shaped steel, so that the entire baffle can be disassembled. The operation is very simple and convenient for on-site operation. At this time, the spring is in a compressed state.

[0020] Furthermore, one end of the pull rod close to the lower clamping plate is connected to a pull ring.

[0022] Furthermore, the pull ring is rotatably connected to the corresponding end of the pull rod.

[0023] The beneficial effect of adopting the above further solution is that the structure is simple, and the corresponding ends of the pull ring and the pull rod are connected in a rotational manner, which is more reasonable and easy to operate.

[0024] Furthermore, the baffle is a long strip-shaped plate structure.

[0040] During assembly, the baffle 1 is connected to the wind turbine terminal tower using two fixing mechanisms. The baffle 1 blocks the drop insurance (equivalent to a switch) and the wind turbine terminal tower to avoid short circuits, making it safer and more reliable.

[0041] Furthermore, a platform is fixedly mounted on the wind turbine terminal tower, and the aforementioned drop safety device is mounted on the platform. Under normal circumstances, the drop safety device is closed on the platform and does not come into contact with the wind turbine terminal tower. When the drop safety device is open, it can come into contact with the wind turbine terminal tower, causing a ground short circuit. Therefore, the baffle 1 provided in this embodiment prevents the drop safety device from coming into contact with the wind turbine terminal tower.

[0042] This embodiment has a simple structure and a reasonable design. The protection device achieves grounding protection by creating a sufficient insulation distance and insulating medium with the tower crossarm in a suspended state after the drop safety is disconnected. At the same time, the device is very easy to assemble, which can meet the actual situation of easy installation on site, saving time and effort.

[0049] This solution has a simple structure and a reasonable design. It uses the gap 12 formed between the upper clamping plate 4 and the fixed bracket 2 to clamp one end of the L-shaped steel 3, and then uses the lower clamping plate 5 to cooperate with the other end of the upper clamping plate 4 to clamp the other end of the L-shaped steel 3, thereby realizing rapid assembly and disassembly of the baffle 1, facilitating on-site operations, saving time and effort.

[0053] Alternatively, the upper splint 4 may also adopt other suitable geometric shapes, such as an arc-shaped structure, to ensure that one end of the upper splint 4 can clamp one end of the L-shaped steel 3 together with the fixed bracket 2, while the other end of the upper splint 4 can cooperate with the lower splint 5 to clamp the other end of the L-shaped steel 3.

At this time, the elastic force of the spring 7 makes the lower clamping plate 5 always clamp the L-shaped steel 3;

[0061] During disassembly, pull down the pull rod 6 to release the lower splint 5 from the L-shaped steel 3, and then rotate the lower splint 5 to make room for disassembling the L-shaped steel 3, so that the entire baffle 1 can be disassembled. The operation is very simple and convenient for on-site operation. At this time, the spring 7 is in a compressed state.

[0062] Preferably, in this embodiment, the pull rod 6 is preferably a cylindrical rod.

[0063] In addition, the two limiting plates 8 are preferably circular plates.

[0064] Example 7

[0065] On the basis of Example 6, in this embodiment, one end of the pull rod 6 close to the lower clamping plate 5 is connected to a pull ring 9 .

[0066] This solution has a simple structure and a reasonable design. The pull ring 9 is used to pull the pull rod 6, which is easy to operate and saves time and effort.

[0074] Example 10

[0075] On the basis of the above embodiments, in this embodiment, a pair of mounting holes 10 are respectively provided at both ends of the baffle 1, and a connecting bolt 11 is respectively installed in each pair of the mounting holes 10, and each pair of the connecting bolts 11 is fixedly connected to the corresponding fixing mechanism.

[0076] This solution has a simple structure. Both ends of the baffle 1 are connected to two fixing mechanisms via connecting bolts 11, respectively, and is easy to assemble.

[0083] Under normal circumstances, the wind turbine terminal tower fuse is always in the closed state. However, the fuse may fall off during operation or in an accident. When the fuse falls off, it is easy for it to come into contact with the wind turbine terminal tower and cause grounding, resulting in a short circuit.

[0086] The wind turbine terminal tower drop insurance anti-grounding tripping protection device provided by the present invention has the following advantages:

[0087] This device achieves grounding protection by creating sufficient insulation distance and insulating medium with the tower crossarm in the suspended state after the drop insurance is disconnected;

[0088] In order to avoid the loss of the collector line caused by the installation of protective devices, the device is designed with a spring-type locking fixed structure for easy installation, which ensures the firmness of the device and meets the actual situation of easy installation on site.

[0089] The elastic potential energy of the spring ensures the 360-degree steerability of the locking mechanism, facilitating on-site installation.
