DETAILED DESCRIPTION

[0021] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0022] Embodiment 1

[0023] An endoscopic inspection device for wind turbine blades, such as Figure 1 As shown, the vehicle includes a body with wheels symmetrically arranged on both sides. The wheels are driven by a drive motor inside the vehicle body. There are three wheels on each side of the vehicle body to ensure that the vehicle body travels stably inside the wind turbine blade. Multiple bullseye wheels are distributed in a circular array on the outer side of the wheels. The bullseye wheels are similar to omnidirectional balls installed on the side of the wheels, which can reduce the friction when the wheels contact the inside of the wind turbine blade. Specifically, the bullseye wheels can also be provided on the sides of the front and rear wheels on both sides of the vehicle body.

[0024] Front and rear cameras are installed at the front and rear ends of the vehicle body, respectively. The front and rear cameras collect video images to complete the inspection and patrol inside the wind turbine blades. The collected images are connected to the machine vision software and processing hardware platform on the host through cables to perform real-time analysis and locate the fault location.

[0025] At the rear of the vehicle body, below the rear-facing camera, is a hinged base. An aviation socket is hinged within the hinged base, and a hinge ear is connected to the end of a connecting sleeve. The hinge ear and the hinged base are rotatably connected via a pivot, and a tightening screw is located on the hinged base near the pivot to secure the hinge ear. The angle of the aviation socket can be adjusted via the pivot. Because there are many positioning blocks inside the wind turbine blade, to prevent collisions with these blocks when the vehicle reverses, before entering the wind turbine blade, the aviation socket is raised 10°-15° by the pivot. Then, the tightening screw secures the hinge ear, raising the aviation socket to a certain angle and fixing it in place. This avoids collisions with the positioning blocks inside the wind turbine blade, preventing damage to the aviation socket and extending its service life.

[0026] Rear low beam lights are located on both sides near the rear camera, and a rear high beam light is located on one side near one of the rear low beam lights. The front camera is an illumination camera, which, together with the rear low beam lights and the rear high beam lights, can illuminate the internal environment of the wind turbine blades.

[0027] The aviation socket includes a connecting sleeve, a connector mounting base that is threaded to the connecting sleeve, and a socket body mounted on the mounting base. The socket body is connected to the host cable to enable power supply and information transmission.

[0028] The upper end of the vehicle body is provided with an upper cover, the periphery of the upper cover is fixed on the vehicle body through screws, the vehicle body is convenient to overhaul and maintain by disassembling the upper cover, the upper end of the two sides of the vehicle body is respectively provided with a support rod, a rotating ring is rotatably sleeved on the support rod, a handle is connected to the rotating ring, the inner contour of the handle is matched with the outer contour of one side of the upper cover, the handle can be clamped on the periphery of one side of the upper cover when the handle is placed down, the upper end of the handle is flush with the upper surface of the upper cover, the whole vehicle body can be lifted and moved through the handle, the handle is clamped on one side of the upper cover when the whole device works in the inner cavity of the wind power blade, so as to avoid occupying the narrow inner space of the wind power blade when the vehicle body works.

[0029] Embodiment 2

[0030] A wind power blade endoscopic detection device, as shown in Figure 2 The difference between the embodiment 1 and the embodiment 2 is that the support rod is two, the hexagonal screw universal ball is connected to the outer end of each support rod, and the two support rods are located above the adjacent two wheels. When the vehicle body moves in the wind power blade and deviates, the universal ball on the hexagonal screw will contact the inner cavity of the wind power blade, so as to reduce the friction between the vehicle body and the inner wall of the wind power blade.

[0031] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
