Description

Technical Field

[0001] The utility model relates to the technical field related to moisture-proofing of generators, and in particular to a moisture-proof device for a wind generator. Background Art

[0002] A wind turbine is a device that converts wind energy into electrical energy. It is mainly composed of blades, generators, mechanical parts and electrical parts. According to the different rotating axes, wind turbines are mainly divided into two categories: horizontal axis wind turbines and vertical axis wind turbines. When the wind turbine is in use, a large amount of water vapor may accumulate on the outside of the operation control box in rainy and snowy weather. The water vapor entering the operation control box may cause moisture, which in turn leads to corrosion and damage of internal components. The moisture-proof structure of existing wind turbines is usually a simple desiccant. When this method is used, its overall moisture-proof effect is limited, and the operation control box cannot be fully and quickly moisture-proofed during use.

[0003] Therefore, we propose a moisture-proof device for a wind turbine to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When the utility model is in use, the hot air in the operation control box can be guided into the shell by the action of the arranged guide fan. At the same time, in the process of guide, the dust and impurities in the air can be filtered through the filter to prevent the dust and impurities from entering the shell. And through the folding design of the protective plate, the rain and snow can be guided to quickly fall off from the outside of the generator during rain and snow. At the same time, the hot air generated in the operation of the generator can be quickly guided by the cooperation of the guide groove and the guide hole, and then the protective plate can be heated to dry the rain and snow on the upper side, so as to reduce the water vapor that may exist around the generator and prevent the water vapor from entering the operation control box and causing moisture.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A moisture-proof device for a wind turbine generator comprises a shell 1. The shell 1 is designed in an inverted trapezoidal shape as a whole. A connecting frame 2 is connected to the lower end surface of the shell 1. The outer wall surface of the connecting frame 2 is covered with a sealing ring structure. A group of mounting plates 201 are connected to the side walls of the connecting frame 2, which is convenient for connecting the connecting frame 2 of the device with an operation control box of an external generator, so as to guide hot air into the shell 1 while dissipating internal heat. A folding protective plate 3 is arranged on the upper side of the shell 1, and a group of guide fans 4 are installed on the lower side of the shell 1. A group of through holes 401 that penetrate inside and outside are opened on the lower end surface of the shell 1. The guide fans 4 are installed in the through holes 401. The operation of the guide fans 4 drives the circulation of hot air.

[0025] A filter 5 is provided in the inner cavity of the shell 1 located on the upper side of the guide fan 4. The filter 5 can filter dust and impurities in the air to prevent dust and impurities from entering the shell 1. Installation grooves 501 are opened on the side walls of the shell 1 on both sides of the filter 5. A collection box 502 is installed inside the installation groove 501. An electric push rod 601 is connected between the cleaning plate 6 and the inner wall of the shell 1. A brush 602 is connected to the lower end surface of the cleaning plate 6. The brush 602 is in contact with the filter 5, which increases the overall cleaning efficiency of the cleaning plate 6 and ensures the cleanliness of the filter 5.

[0026] A group of cleaning plates 6 are arranged on the upper side of the filter 5, a guide groove 7 is opened on the inner wall of the protective plate 3, a group of guide holes 701 are opened on the side wall of the guide groove 7, and the outer ends of a group of guide holes 701 extend to the outside of the protective plate 3. By utilizing the cooperation of the guide groove 7 and the guide holes 702, the hot air generated during the operation of the generator can be quickly guided, thereby heating the protective plate 3.

[0027] A group of baffles 8 are arranged in the inner cavity of the shell 1 located on the lower side of the protective plate 3. In the normal state, the baffles 8 block the guide grooves 7 and the guide holes to prevent air exchange between the inner cavity space of the shell 1 and the external environment. A reset mechanism 9 is arranged between the group of baffles 8 and the inner wall of the shell 1. The reset mechanism 9 includes a main shaft 901 connected to the inner wall of the shell 1, and a sleeve 902 is connected to one end of the baffle 8 close to the main shaft 901. A reset spring 903 is connected between the main shaft 901 and the inner wall of the sleeve 902. The force of the coil spring 903 can drive the baffle 8 to rotate quickly, and then return to its original position to close the inner cavity space of the internal shell 1, thereby preventing external air from flowing into the shell 1 during normal circulation.

[0028] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

[0029] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
