[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model provides a technical solution: a blade clearance monitoring device that is easy to install, comprising: a blade clearance monitoring device body 1, a T-shaped block 101 fixedly connected to the top of the blade clearance monitoring device body 1, a triangular fixing groove 102 extending through one side of the T-shaped block 101, a chamfer 103 on one end of the surface of the T-shaped block 101, a handle 104 fixedly connected to the other end of the T-shaped block 101, a quick installation and disassembly assembly 2 provided on the surface of the T-shaped block 101, and an easy installation assembly 3 provided on one side of the quick installation and disassembly assembly 2.

[0026] Specifically: Two bolts 307 are inserted into the bolt mounting holes 305 and hexagonal bolt fixing slots 306 at both ends of the fixing clamp 2 302. Then, the surfaces of the two bolts 307 are embedded into the bolt mounting holes 305 at both ends of the fixing clamp 1 301. Two nuts 308 are installed on the surfaces of the bolts 307 and tightened for fixation. This design facilitates the installation of the blade clearance monitoring device. Under the action of the spring force of the spring 211, the triangular column 209 moves downward into the inner cavity of the triangular fixing slot 102 to fix the T-block 101. When disassembling, one hand holds the handle 210 and pulls it upward, and the other hand can pull the handle 104 to pull the T-block 101 out of the inner cavity of the T-slot 1 202. This design facilitates the installation and disassembly of the blade clearance monitoring device. The blade clearance monitoring device body 1 is an existing wind power blade clearance monitoring device. The specific structure is not described here.

[0027] In one embodiment, the quick-installation and disassembly assembly 2 includes an installation block 201. A T-slot 202 is provided on one side of the installation block 201. A triangular column movable groove 203 is provided at the top of the inner cavity of the T-slot 202. A plurality of connecting rod movable grooves 204 are provided at equal intervals through the top of the inner cavity of the triangular column movable groove 203. A plurality of sleeves 205 are fixedly connected at equal intervals to the top of the inner cavity of the triangular column movable groove 203. A T-slot 206 is provided at the bottom of each of the multiple sleeves 205. The multiple T-slots 206 communicate with the inner cavities of the multiple connecting rod movable grooves 204. A spring 211 is fitted on the surface of each of the multiple sleeves 205. The top of the multiple springs 211 is fixedly connected to the top of the inner cavity of the triangular column movable groove 203.

[0028] Specifically, such as Figure 4-6 As shown: The triangular post 209 and the sleeve 205 cooperate to limit the upward movement of the connecting rod 207 and prevent the limiting plate 208 from disengaging from the inner cavity of the T-slot 206 and the connecting rod movable slot 204.

[0029] In one embodiment, connecting rods 207 are movably embedded in the inner cavities of multiple T-slots 206, and limiting plates 208 are fixedly sleeved on the surfaces of multiple connecting rods 207. The surfaces of multiple limiting plates 208 are movably fitted into the inner cavities of multiple T-slots 206. Triangular posts 209 are fixedly connected to the bottom ends of multiple connecting rods 207, and gripping rods 210 are fixedly connected to the top ends of multiple connecting rods 207. The bottom ends of multiple springs 211 are fixedly connected to the top ends of triangular posts 209. The surfaces of multiple connecting rods 207 are movably embedded in the inner cavities of multiple T-slots 206. The surfaces of triangular posts 209 are movably fitted into the inner cavities of triangular post movable grooves 203 and triangular post 209 are movably fitted into the interior of triangular fixed grooves 102.

[0030] Specifically, such as Figure 4-6 As shown: The limiting plate 208 and the second T-slot 206 cooperate to ensure that a portion of the surface of the triangular post 209 is always partially embedded in the inner cavity of the triangular post movable slot 203, so that when the T-block 101 is inserted into the first T-slot 202, the triangular post 209 can be embedded in the inner cavity of the triangular fixed slot 102.

[0031] In one embodiment, the easy-to-install component 3 includes a first fixing hoop 301 and a second fixing hoop 302. Anti-slip pads 303 are fixedly connected to the inner sides of both the first fixing hoop 301 and the second fixing hoop 302. Mounting plates 304 are fixedly connected to both ends of the first fixing hoop 301 and the second fixing hoop 302. Bolt mounting holes 305 are opened through the sides of the four mounting plates 304.

[0032] Specifically, such as Figure 1-3 As shown: Anti-slip mat 303 can increase the friction between the object and the contact surface, and prevent the displacement of fixing hoop 1 301 and fixing hoop 2 302.

[0033] In one embodiment, a hexagonal bolt fixing groove 306 is provided at one end of the inner cavity of the two bolt mounting holes 305 at both ends of the fixing hoop 2 302. The four mounting plates 304 are arranged in pairs of opposite sides. Bolts 307 are movably embedded in the inner cavity of both sets of mounting plates 304. The surfaces of one end of the two bolts 307 are movably fitted into the inner cavity of the two hexagonal bolt fixing grooves 306. Nuts 308 are threaded onto the surfaces of the two bolts 307.

[0034] Specifically, such as Figure 3 As shown: Bolt 307 and nut 308 are commonly used fastening structures that can fasten fixing clamp 301 and fixing clamp 302. The opening size of mounting plate 304 is slightly larger than the size of the main body surface of bolt 307, but smaller than the size of the nut 308 and the surface of one end of bolt 307.

[0035] In one embodiment, the surface of the T-block 101 is movably embedded inside the T-slot 202.

[0036] Specifically, such as Figure 1-2 As shown: The chamfer 103 facilitates the alignment of the T-block 101 with the inner cavity of the T-slot 202.

[0037] In one embodiment, one side of the mounting block 201 is fixedly connected to the surface of one side of the fixing hoop 301.

[0038] Specifically, such as Figure 1 As shown: Fix the mounting block 201 to the surface of the fixing hoop 301 to fix and support the mounting block 201.

[0039] Working principle: In the initial state, fixing clamp 1 301 and fixing clamp 2 302 are separated, and there is no fixing by bolt 307 and nut 308.

[0040] Insert two bolts 307 into the bolt mounting holes 305 and hexagonal bolt fixing slots 306 at both ends of the fixing hoop 2 302. Then place the fixing hoop 2 302 in a suitable position in the upper part of the wind turbine tower. Embed the surfaces of the two bolts 307 into the bolt mounting holes 305 at both ends of the fixing hoop 1 301. Install two nuts 308 on the surfaces of the bolts 307 and tighten them with a nut installation tool. Then, insert the T-shaped block 101 on the top of the blade clearance monitoring device body 1 into the T-shaped slot 1 202 to install the blade clearance monitoring device body 1.

[0041] This design eliminates the need for welding or drilling on the tower to install the blade clearance monitoring device, making the installation of the blade clearance monitoring device easier.

[0042] When the T-block 101 is inserted into the inner cavity of the T-slot 202, the triangular post 209 is pressed by the T-block 101 into the inner cavity of the triangular post movable groove 203 and moves upward. The spring 211 is deformed by the force. When the triangular fixing groove 102 of the T-block 101 moves to the bottom of the triangular post 209, the triangular post 209 loses the limit of the T-block 101. Under the action of the elastic force of the spring 211, the triangular post 209 moves downward into the inner cavity of the triangular fixing groove 102 and fixes the T-block 101, thus completing the installation of the blade clearance monitoring device.

[0043] During disassembly, hold the handle 210 with one hand and pull it upward. The connecting rod 207 and the triangular post 209 move upward with the handle 210. The triangular post 209 compresses the spring 211, causing the spring 211 to deform until the triangular post 209 is completely disengaged from the inner cavity of the triangular fixing groove 102. After the triangular post 209 is no longer restrained, the other hand can pull the handle 104 to pull the T-block 101 out of the inner cavity of the T-slot 202, thus completing the disassembly of the blade clearance monitoring device.

[0044] This design facilitates the installation and removal of the blade clearance monitoring device, and also makes it easier to replace the blade clearance monitoring device in the future.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
