DETAILED DESCRIPTION

[0020] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0021] Embodiment 1

[0022] like Figures 1 to 3As shown, a hatch hingeless wind turbine hub hatch cover includes a base body 1 installed on the wind turbine hub and a cover body connected to the base body 1, and the cover body is provided with a plurality of limiting coaxial handles 4, and the locking blocks 41 of the plurality of limiting coaxial handles 4 cooperate with the locking edges 11 of the base body 1 for connecting the cover body and the base body 1.

[0023] Compared with traditional hatch covers, the hatch cover provided in this embodiment eliminates the hinge between the base body 1 and the cover body, and uses multiple limiting coaxial handles 4 to achieve multi-point limiting of the base body 1 and the cover body, so that there is no fixed connection between the two. The elimination of the traditional hinged structure can avoid space occupation inside the base body 1, which has outstanding advantages under the requirement of long hub channel. In addition, in the production and assembly links of the hatch cover, the hinge-free design can reduce component costs and assembly costs.

[0024] Among them, the bottom of the seat body 1 is provided with a low edge connected to the wind turbine hub, the locking edge 11 is arranged on the inner wall of the seat body 1, and the top of the seat body 1 is provided with a limiting edge 12 for limiting the cover body. Specifically, the seat body 1 is a thin-walled rotary structure, the locking edge 11 is a protrusion on the inner wall of the seat body 1, and the limiting coaxial handle 4 is preferably a handle with application number CN202221095760.1. When in use, the locking block 41 can be rotated by stretching or pressing along the axial direction, which has the effect of preventing accidental opening. The close contact between multiple locking blocks 41 and the locking edge 11 fixes the cover body to the seat body 1, and the number of limiting coaxial handles 4 is not less than two. In particular, the seat body 1 is preferably a circular structure because the force effect of the circle is better during rotation, but it is not limited to a circle, and other structures that meet the requirements of the hub are also acceptable.

[0025] A sealing gasket 5 is provided between the seat 1 and the cover, and the sealing gasket 5 is mounted on the cover, and the sealing gasket 5 matches the limiting edge 12. In addition to sealing the gap, the sealing gasket 5 also increases friction to prevent the cover from rotating and stabilizing the contact point between the locking block 41 and the locking edge 11.

[0026] The cover body includes a central through plate 2 and a rainproof wind cap 3 installed on the central through plate 2, the rainproof wind cap 3 is connected with the central through plate 2 to form an air duct, a plurality of limit-type coaxial handles 4 are evenly distributed on the central through plate 2, and a sealing gasket 5 is arranged on the central through plate 2. The cover body combines the rainproof wind cap 3 with the central through plate 2, so that the hatch cover has the function of ventilation and heat dissipation.

[0027] The rainproof wind cap 3 includes a rainproof seat 31 and a ventilation cover 32. The rainproof seat 31 is installed on the central plate 2, and the ventilation cover 32 is covered on the rainproof seat 31. A tortuous ventilation path is formed between the rainproof seat 31 and the ventilation cover 32. The tortuous ventilation path has an advantage in rainproofing, so that the hatch cover has good heat dissipation capacity while having rainproof and dustproof effects.

[0028] A handlebar turning mark is provided on the position-limiting coaxial handle 4. The handlebar turning mark is used to indicate the opening and locking direction of the position-limiting coaxial handle 4 to avoid accidental opening of the handle.

[0029] In particular, a connecting belt may be provided between the base body 1 and the cover body to limit the separation distance of the cover body and prevent it from being accidentally lost.

[0030] Embodiment 2

[0031] This embodiment is an improvement on the cover structure in the first embodiment. Specifically, the cover of this embodiment includes a blind plate 6 and a gripping handle 7 mounted on the blind plate 6. A plurality of coaxial limit handles are evenly distributed on the blind plate, and a sealing gasket 5 is arranged on the blind plate 6. In places where a higher sealing level is required, a plate-shaped cover can be selected.

[0032] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
