[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-5 As shown, this embodiment is a wind turbine unit fault detection device, including:

[0031] Unit components, the unit components including fan housing 100 and detection housing 101;

[0032] The folding component includes a support frame 200, an inner groove 201, a rotating shaft 202, a groove 203, a limiting groove 204, a pin frame 205, a baffle 206, a handle 207, a limiting plate 208, a pin plate 209, and a vertical plate 210. The inner groove 201 is provided in the middle of one side of the outer surface of the fan housing 100. The rotating shaft 202 is connected to the lower part of the inner surface of the inner groove 201. The support frame 200 is rotatably connected to the outer surface of the rotating shaft 202. A set of grooves 203 are symmetrically provided at both ends of the inner surface of the inner groove 201. The baffle 206 is connected to the inside of the groove 203. A set of pin frames 205 are symmetrically connected to the bottom of the support frame 200. The pin plate 209 is connected to one side of the outer surface of the baffle 206 and inserted into the inside of the pin frame 205.

[0033] After the test is completed, the test housing 101 is disassembled. The support housing is rotated and folded inside the inner groove 201 via the rotating shaft 202. The upright plate 210 is pushed so that the baffle 206 blocks the outside of the support frame 200. At the same time, the pin plate 209 is inserted into the pin groove to fix it, thus fixing the folded support frame 200.

[0034] Limiting grooves 204 are provided at the top and bottom of the inner surface of the tank 203, and limiting plates 208 are connected to the top and bottom of the baffle 206. The limiting plates 208 are movably connected inside the limiting grooves 204.

[0035] When the clamping plate 302 is pushed, the limiting plate 208 moves inside the limiting groove 204 at the same time, which can play a supporting role.

[0036] The other end of the outer surface of the baffle 206 is connected to the upright plate 210, which is connected to both ends of the outer surface of the fan housing 100. The handle 207 is connected to one end of the outer surface of the upright plate 210, and the detection housing 101 is located on the inner surface of the support frame 200.

[0037] The upright plate 210 blocks the outside of the fan housing 100, and the pin plate 209 blocks the inside of the inner groove 201, which can cause instability when it is pulled out or pushed out.

[0038] The working principle is as follows: First, when the fan casing 100 needs to be inspected, the support frame 200 is rotated and unfolded via the rotating shaft 202. The support frame 200 is supported at the bottom of the inner surface of the inner groove 201. The inspection casing 101 is placed inside the support frame 200 for inspection. After the inspection is completed, the inspection casing 101 is disassembled. The support casing is rotated and folded inside the inner groove 201 via the rotating shaft 202. The upright plate 210 is pushed and moves inside the limiting groove 204 via the limiting plate 208, so that the baffle 206 blocks the outside of the support frame 200. At the same time, the pin plate 209 is inserted into the pin groove to fix it, thus fixing the folded support frame 200. This achieves the folding and storage of the support structure, avoiding the problem of occupying space and improving the versatility and flexibility of the support structure.

[0039] Please see Figures 1-5 As shown, this embodiment, based on the above embodiment, further includes a fixing component. The fixing component includes an internal threaded ring 300, a positioning plate 301, a clamping plate 302, a snap-fit ​​groove 303, a snap-fit ​​block 304, a slider 305, a support rod 306, a spring 307, a turntable 308, a threaded rod 309, and a handle 310. The internal threaded ring 300 is connected to the middle of one side of the outer surface of the support frame 200. The threaded rod 309 is connected inside the threaded ring. The handle 310 is rotatably connected to one side of the threaded rod 309. The turntable 308 is connected to the other side of the threaded rod 309. The positioning plate 301 is connected to one side of the turntable 308 and clamps the outer side of the detection housing 101.

[0040] After the testing housing 101 is placed inside the support frame 200, the threaded rod 309 is rotated to push the positioning plate 301, so that the positioning plate 301 is clamped on the outside of the testing housing 101.

[0041] The positioning plate 301 has clamping plates 302 symmetrically connected to both ends of one side of its outer surface. A slider 305 is connected to one side of the clamping plate 302. The positioning plate 301 has symmetrically opened grooves inside. The slider 305 is movably connected inside the groove. The support rod 306 is connected inside the groove. The spring 307 is wound around the outer surface of the support rod 306 and located at both ends of the outer surface of the slider 305.

[0042] The spring 307 generates elastic force, which can stretch the clamping plate 302. The spring 307 rebounds, so that the clamping plate 302 is clamped at both ends of the detection housing 101.

[0043] One end of the outer surface of the clamping plate 302 is connected to a snap-fit ​​block 304, and the two ends of the outer surface of the detection housing 101 are provided with snap-fit ​​grooves 303, and the snap-fit ​​block 304 is inserted into and connected to the inside of the snap-fit ​​groove 303.

[0044] When the clamping plate 302 is clamped at both ends of the testing housing 101, the snap-fit ​​block 304 is simultaneously fixed inside the snap-fit ​​groove 303.

[0045] The working principle is as follows: First, the spring 307 generates elastic force, pulling the clamping plates 302 at both ends. After the detection housing 101 is placed inside the support frame 200, the threaded rod 309 is rotated to push the positioning plate 301, so that the positioning plate 301 is clamped on the outside of the detection housing 101. The spring 307 rebounds, so that the clamping plates 302 are clamped on both ends of the detection housing 101. The snap-fit ​​block 304 is fixed inside the snap-fit ​​groove 303, which can position the detection housing 101. This can avoid the problem of insufficient stability of the detection device in complex environments, and ensure that the faults of the wind turbine unit can be continuously and accurately monitored and diagnosed under various complex working conditions.
