Description

Technical Field

[0001] This utility model belongs to the field of wind power generation technology, and in particular relates to a wind turbine generator cover structure that is easy to inspect, disassemble and install. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which then drives the rotor to rotate and ultimately outputs alternating current. The wind turbine's cover and the connecting flange are detachably connected by bolts, and the connecting flange is then welded to the protective shell for fixation.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] Existing technology uses bolts to fix the wind turbine cover. However, the cover and the connecting flange are subjected to external forces such as vibration and wind during operation, which can easily cause the bolts to loosen, affecting the stability and sealing of the connection. Moreover, when disassembly is required, multiple bolts need to be removed with tools, which is a troublesome process. Therefore, a wind turbine cover structure that is easy to inspect and disassemble is proposed to solve the above problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a wind turbine generator cover structure that is easy to inspect, disassemble, and install. It has the advantage of convenient disassembly and can overcome the above-mentioned problems or at least partially solve the problem that the generator cover and the connecting flange are subjected to external forces such as vibration and wind during operation, which can easily lead to loosening of bolts, affecting the stability and sealing of the connection. Moreover, when disassembly and installation are required, multiple bolts need to be removed with the help of tools, which is a rather troublesome process.

[0006] This utility model is implemented as follows: a wind turbine generator cover structure that is easy to inspect, disassemble and install includes a generator housing, a cover body and a mounting groove. The top of the generator housing is movably connected to the bottom of the cover body, and the mounting groove is opened on the rear side of the generator housing.

[0007] The bottom of the mounting slot is provided with a moving hole, and positioning components are provided on the left and right sides of the inner cavity of the mounting slot.

[0008] A linkage component is disposed within the inner cavity of the mounting slot.

[0009] As a preferred embodiment of this utility model, a sealing groove is provided on the top of the generator housing, and a sealing ring is inserted into the inner cavity of the sealing groove. The top of the sealing ring is fixedly connected to the cover. By setting the sealing groove and the sealing ring, after the generator housing is connected to the cover, the sealing ring will be inserted into the sealing groove, and the connection can be sealed, so that rainwater will not enter the generator housing.

[0010] As a preferred embodiment of this utility model, the generator housing has insertion slots on both the left and right sides of its inner cavity. An L-shaped plate is inserted into the inner cavity of the insertion slot. By setting the insertion slot and the L-shaped plate, after the generator housing is connected to the cover, the L-shaped plate is inserted into the insertion slot, which fixes the position of the cover and prevents the cover from detaching.

[0011] In a preferred embodiment of this invention, the linkage assembly includes two movable plates, each with an L-shaped rod fixedly connected to an opposite side. The bottom of the L-shaped rod passes through a movable hole and is fixedly connected to an L-shaped plate. A tension spring is sleeved on the surface of the L-shaped rod, and the side of the tension spring closest to the movable plate is fixedly connected to the movable plate. By setting a positioning assembly, after the L-shaped plate is inserted into the insertion slot, the tension spring applies force to the movable plate, thus preventing the movable plate from pulling the L-shaped plate off.

[0012] As a preferred embodiment of this utility model, a positioning plate is fixedly connected to the top of the mounting groove, and the number of positioning plates is six. The positioning plate has a positioning hole on the side near the L-shaped rod that cooperates with the L-shaped rod. The L-shaped rod is movably connected to the inner cavity of the positioning hole. The tension spring is fixedly connected to the positioning plate on the side near the positioning plate. By setting the positioning plate and the positioning hole, when the movable plate moves the L-shaped rod, the positioning plate and the positioning hole can control the movement position of the L-shaped rod and the movable plate, so that the movable plate will not move randomly when it moves.

[0013] In a preferred embodiment of this invention, the linkage assembly includes two rotating plates. The bottom of each rotating plate is rotatably connected to the inner wall of the mounting groove via a rotating shaft. The top of each rotating plate has a pressing hole, and a pressing rod is movably connected to the inner cavity of the pressing hole. The top and bottom of the pressing rod are fixedly connected to the movable plate. By setting the linkage assembly, when it is necessary to move the two movable plates closer to each other, the pressing plate will press the two rotating plates closer to each other and rotate them. The rotation of the rotating plates will press the pressing rod through the pressing hole, and the movement of the pressing rod will move the two movable plates closer to each other.

[0014] In a preferred embodiment of this invention, control slots are provided on both the left and right sides of the mounting groove cavity. Control blocks are movably connected to the inner cavities of the control slots. Extrusion plates are fixedly connected to the opposite sides of the two control blocks. The side of the extrusion plate closest to the rotating plate contacts the rotating plate. By providing control slots, control blocks, and extrusion plates, pushing the extrusion plates can drive the two rotating plates to rotate. The control blocks and control slots can control the movement position of the extrusion plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model utilizes a positioning component, a linkage component, a sealing groove, a sealing ring, a plug groove, and an L-shaped plate in combination. When the L-shaped rod drives the L-shaped plate out of the plug groove, the cover is pulled up, causing the sealing ring to disengage from the sealing groove. At this point, the cover can be disassembled to repair the devices inside the generator housing. This solves the problem that during operation, the generator cover and the connecting flange are subject to external forces such as vibration and wind, which can easily cause the bolts to loosen, affecting the stability and sealing of the connection. Furthermore, disassembly and assembly require the use of tools to remove multiple bolts, which is a cumbersome process. Attached Figure Description

[0022] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown in the figure, the present invention provides a wind turbine generator cover structure that is easy to inspect and disassemble, including a generator housing 1, a cover 2 and a mounting groove 3. The top of the generator housing 1 is movably connected to the bottom of the cover 2, and the mounting groove 3 is opened on the rear side of the generator housing 1.

[0025] The bottom of the mounting slot 3 is provided with a moving hole 4, and positioning components 5 are provided on the left and right sides of the inner cavity of the mounting slot 3.

[0026] Linkage component 6 is located inside the mounting slot 3.

[0027] refer to Figure 2 and Figure 4 A sealing groove 7 is provided on the top of the generator housing 1, and a sealing ring 8 is inserted into the inner cavity of the sealing groove 7. The top of the sealing ring 8 is fixedly connected to the cover 2.

[0028] Using the above solution: By setting a sealing groove 7 and a sealing ring 8, after the generator housing 1 is connected to the cover 2, the sealing ring 8 will be inserted into the sealing groove 7, which can seal the connection and prevent rainwater from entering the generator housing 1.

[0029] refer to Figure 3 and Figure 4 The generator housing 1 has insertion slots 9 on both the left and right sides of its inner cavity, and L-shaped plates 10 are inserted into the inner cavity of the insertion slots 9.

[0030] Using the above solution: By setting the plug-in slot 9 and the L-shaped plate 10, after the generator housing 1 is connected to the cover 2, the L-shaped plate 10 is inserted into the plug-in slot 9, which can fix the position of the cover 2 so that the cover 2 will not detach.

[0031] refer to Figure 4 The linkage component 6 includes two movable plates 51. An L-shaped rod 52 is fixedly connected to the opposite side of each of the two movable plates 51. The bottom of the L-shaped rod 52 passes through the moving hole 4 and is fixedly connected to the L-shaped plate 10. A tension spring 53 is sleeved on the surface of the L-shaped rod 52. The side of the tension spring 53 closest to the movable plate 51 is fixedly connected to the movable plate 51.

[0032] Using the above solution: After the L-shaped plate 10 is inserted into the insertion slot 9 by setting the positioning component 5, the tension spring 53 applies a pulling force to the movable plate 51, so that the movable plate 51 will not cause the L-shaped plate 10 to detach.

[0033] refer to Figure 4 The top of the mounting groove 3 is fixedly connected to a positioning plate 11, and there are six positioning plates 11. The positioning plate 11 has a positioning hole 12 on the side near the L-shaped rod 52, which is used to cooperate with the L-shaped rod 52. The L-shaped rod 52 is movably connected to the inner cavity of the positioning hole 12. The tension spring 53 is fixedly connected to the positioning plate 11 on the side near the positioning plate 11.

[0034] By adopting the above solution: by setting the positioning plate 11 and the positioning hole 12, when the movable plate 51 drives the L-shaped rod 52 to move, the positioning plate 11 and the positioning hole 12 can control the movement position of the L-shaped rod 52 and the movable plate 51, so that the movable plate 51 will not move randomly when it moves.

[0035] refer to Figure 4The linkage component 6 includes two rotating plates 61. The bottom of the rotating plate 61 is rotatably connected to the inner wall of the mounting groove 3 via a rotating shaft. The top of the rotating plate 61 is provided with a pressing hole 62. The inner cavity of the pressing hole 62 is movably connected to a pressing rod 63. The top and bottom of the pressing rod 63 are fixedly connected to the movable plate 51.

[0036] Using the above solution: By setting the linkage component 6, when it is necessary to move the two movable plates 51 closer to each other, the extrusion pull plate 15 will extrude the two rotating plates 61 closer to each other and rotate them. The rotation of the rotating plates 61 will extrude the extrusion rod 63 through the extrusion hole 62. The movement of the extrusion rod 63 will move the two movable plates 51 closer to each other.

[0037] refer to Figure 4 Control slots 13 are provided on the left and right sides of the inner cavity of the mounting slot 3. Control blocks 14 are movably connected to the inner cavity of the control slots 13. Extrusion plates 15 are fixedly connected to the opposite sides of the two control blocks 14. The side of the extrusion plate 15 closest to the rotating plate 61 contacts the rotating plate 61.

[0038] The above scheme is adopted: by setting up control groove 13, control block 14 and extrusion pull plate 15, when the extrusion pull plate 15 is pushed, it can drive the two rotating plates 61 to rotate. Control block 14 and control groove 13 can control the moving position of extrusion pull plate 15.

[0039] The working principle of this utility model:

[0040] When in use, grip the squeeze plate 15 and push it forward. The squeeze plate 15 will squeeze the two rotating plates 61 closer together and rotate them. The rotation of the rotating plates 61 will squeeze the squeeze rod 63 through the squeeze hole 62. The movement of the squeeze rod 63 will drive the two movable plates 51 closer together. The movement of the movable plates 51 will drive the L-shaped rod 52 to move and pull the tension spring 53. After the L-shaped rod 52 drives the L-shaped plate 10 to disengage from the insertion groove 9, pull up the cover 2 and drive the sealing ring 8 to disengage from the sealing groove 7. At this time, the cover 2 can be removed to repair the device inside the generator housing 1.

[0041] In summary, this wind turbine cover structure, which facilitates maintenance and disassembly, utilizes a combination of positioning component 5, linkage component 6, sealing groove 7, sealing ring 8, insertion groove 9, and L-shaped plate 10. When the L-shaped rod 52 pulls the L-shaped plate 10 out of the insertion groove 9, the cover 2 is pulled up, causing the sealing ring 8 to disengage from the sealing groove 7. At this point, the cover 2 can be disassembled to repair the devices inside the generator housing 1. This solves the problem that during operation, the generator cover and connecting flange are subject to external forces such as vibration and wind, which can easily cause bolts to loosen, affecting the stability and sealing of the connection. Furthermore, disassembly and assembly require the use of tools to remove multiple bolts, which is a cumbersome process.
