[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a fault detection device for power generation equipment, comprising: Support rod 1, with an anti-slip handle 11 fixedly installed at the end of support rod 1; The turning adjustment mechanism 2 is mounted on the support rod 1 and is used to turn and adjust the detection position. Fault detection mechanism 3 is installed on the turning adjustment mechanism 2 and is used to perform fault detection work. The adjustment mechanism 2 includes a supporting frame 21 and a sliding sleeve 24. The supporting frame 21 is fixedly installed at the end of the support rod 1. A rotating seat 22 is rotatably connected to the inner wall of the supporting frame 21, and a gear 23 is rotatably connected to the outer wall of the supporting frame 21. The end of the rotating seat 22 is fixedly connected to the side of the gear 23. The sliding sleeve 24 is slidably connected to the outer wall of the support rod 1. A connecting arm 25 is fixedly installed on the outer wall of the sliding sleeve 24, and a rack 26 is fixedly installed on the connecting arm 25. The top of the rack 26 meshes with the bottom of the gear 23. The adjustment mechanism is adjusted by the length of the support rod 1 itself. The increased distance between the main body 39 of the leakage current detector and the user's hand facilitates fault detection of the power generation equipment from a greater distance. The anti-slip handle 11 design makes it easy for the user to hold the device. The sliding sleeve 24 slides on the outer wall of the support rod 1, and the rack 26 can be moved by the connecting arm 25. Since the rack 26 meshes with the gear 23, the rotating seat 22 can be rotated inside the supporting frame 21. This allows the position of the main body 39 of the leakage current detector to be bent and adjusted, making it easier to carry out fault detection work in a space-constrained environment.

[0018] As one implementation method in this embodiment, such as Figure 3 As shown, the turning adjustment mechanism 2 also includes a fixing kit 28, which is fixedly sleeved on the outer wall of the support rod 1. A limit rod 281 is fixedly installed on the outer wall of the fixing kit 28, and a sliding sleeve 282 is slidably connected to the outer wall of the limit rod 281. The sliding sleeve 282 is slidably connected to the outer wall of the support rod 1, and an elastic element 284 is fixedly installed on the outer wall of the sliding sleeve 282. One end of the elastic element 284 away from the sliding sleeve 282 is fixedly installed on the outer wall of the fixing kit 28. In the initial state, the sliding sleeve 282 can be pulled by the tension of the elastic element 284, causing the sliding sleeve 282 to fit against the middle of the limit rod 281 for positioning. At this time, the main body 39 of the leakage current detector is located on the straight line of the support rod 1. Pushing the sliding sleeve 282 away from the fixing kit 28, the sliding sleeve 24 is pushed by the transmission of the connecting rod 27, thereby bending and adjusting the position of the main body 39 of the leakage current detector.

[0019] As one implementation method in this embodiment, such as Figure 3 As shown, a first positioning bolt 283 is threadedly connected to the outer wall of the sliding sleeve 282. A connecting rod 27 is fixedly installed on the outer wall of the sliding sleeve 282. The end of the connecting rod 27 away from the sliding sleeve 282 is fixedly installed on the outer wall of the sliding sleeve 24. If it is necessary to temporarily lock the leakage current detector body 39 in a bent state, tighten the first positioning bolt 283 so that its threaded end fits against the outer wall of the limit rod 281 to lock it.

[0020] As one implementation method in this embodiment, such as Figure 4 As shown, the fault detection mechanism 3 includes a cylinder 31, which is fixedly installed on the outer wall of the rotating seat 22. An extension rod 33 is slidably connected to the inner wall of the cylinder 31. By sliding the extension rod 33 in the inner cavity of the cylinder 31, the distance between the main body 39 of the leakage current detector and the support rod 1 can be adjusted, which facilitates the smooth progress of fault detection.

[0021] As one implementation method in this embodiment, such as Figure 4 As shown, a second positioning bolt 32 is threadedly connected to the outer wall of the cylinder 31. The threaded end of the second positioning bolt 32 is in movable contact with the outer wall of the extension rod 33. The end of the extension rod 33 is detachably connected to a clamping frame 34. After sliding and adjusting the extension rod 33 inside the cylinder 31, tighten the second positioning bolt 32 to make the threaded end of the second positioning bolt 32 fit against the outer wall of the extension rod 33 for positioning. The extension rod 33 and the clamping frame 34 are assembled by four evenly distributed bolts. Users can replace the clamping frame 34 of different sizes as a whole.

[0022] As one implementation method in this embodiment, such as Figure 4 As shown, a threaded part 35 is threadedly connected to the inner wall of the clamping frame 34, and a rotating handle 36 is fixedly installed at the end of the threaded part 35. The design of the rotating handle 36 makes it convenient for the user to rotate the threaded part 35.

[0023] As one implementation method in this embodiment, such as Figure 4 As shown, a pad 37 is rotatably connected to the end of the threaded part 35 away from the handle 36. A rubber pad 38 is fixedly connected to the outer wall of the pad 37. The leakage current detector body 39 is detachably connected to the side of the rubber pad 38 away from the pad 37. The leakage current detector body 39 is placed between the two rubber pads 38. The handle 36 is then rotated to drive the threaded part 35 to rotate, which causes the rubber pad 38 to abut against the outer wall of the leakage current detector body 39, thus completing the installation of the leakage current detector body 39. The installation of the leakage current detector body 39 can be completed by rotating the handle 36 in the opposite direction. This design facilitates the replacement of different leakage current detector bodies 39 by the user. Different leakage current detector bodies 39 refer to other existing fault detection fixtures used in power generation equipment.

[0024] Working principle: In use, one hand holds the device from the anti-slip handle 11. Through the overall design of the turning adjustment mechanism 2 and the fault detection mechanism 3, combined with the length of the support rod 1, the distance between the main body 39 of the leakage current detector and the user's hand is increased, facilitating fault detection. In environments with limited space, if it is necessary to bend and adjust the main body 39 of the leakage current detector, push the sliding sleeve 282 away from the fixed assembly 28. Through the transmission of the connecting rod 27, the sliding sleeve 24 is pushed, and the connecting arm 25 can drive the rack 26 to move horizontally. Since the rack 26 meshes with the gear 23, the rotating seat 22 can be rotated inside the supporting frame 21, thereby bending and adjusting the position of the main body 39 of the leakage current detector. If it is necessary to temporarily lock the main body 39 of the leakage current detector in the bent state, tighten the first positioning bolt 283.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
