Description

Technical Field

[0001] The utility model relates to the field of wind power generation, and particularly relates to a battery cabinet of a wind turbine generator. Background Art

[0002] The structure of the battery cabinet of the traditional wind turbine generator adopts the structure of a battery pack. The battery pack is designed according to the size of the battery cabinet, covering the entire battery cabinet, and then leaving a very small space for the charger. The main reason is that the traditional battery pack adopts a symmetric design. Its length will match the battery cabinet to ensure installation, but its width is very short while ensuring symmetry. The charger is in the gap at the symmetric center of them. Such a design has the following problems: the installation efficiency of the battery pack is low each time; the battery pack and the charger need to be installed with the cabinet separately; due to space limitations, only small-sized chargers can be selected for the charger specifications.

[0003] To solve the above problems, a series of improvements have been made. Content of the Utility Model

[0004] The purpose of the utility model is to provide a battery cabinet of a wind turbine generator to overcome the above-mentioned drawbacks and deficiencies of the prior art.

[0005] A battery cabinet of a wind turbine generator includes: a cabinet body, a bottom plate, a capacitor bracket, a capacitor and a charger. The bottom plate is connected to the bottom of the cabinet body. The capacitor bracket and the charger are connected to the bottom plate. The capacitor is arranged in the capacitor bracket.

[0006] Among them, the capacitor bracket includes: side plates, a back plate, a mounting plate, avoidance holes, mounting holes and handling openings. The side plates are symmetrically arranged at both ends of the mounting plate. The side plates are of an L-shaped structure. Avoidance holes and mounting holes are provided at the front ends of the side plates. Handling openings are provided on both sides of the side plates. The back plate is connected to the side plates and the mounting plate. Mounting holes are provided on the back plate. The front ends of the side plates and the back plate are connected to the capacitor through the mounting holes. The mounting plate is connected to the bottom plate.

[0007] Advantages of the Utility Model

[0008] Compared with the traditional technology, the utility model realizes an integrated installation structure of the capacitor and the charger through the bottom plate; and avoids the problem that the capacitor cannot be installed through the capacitor bracket. Description of the Drawings

[0018] The following further illustrates the present utility model in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0019] Embodiment 1

Figure 3 It is a structural schematic diagram of the capacitor bracket. Figure 4 It is a structural schematic diagram of a traditional battery cabinet for a wind turbine generator. Figure 5 It is a structural schematic diagram of partial improved effects of a traditional battery cabinet for a wind turbine generator.

[0021] As Figure 1-2 shown, a battery cabinet for a wind turbine generator includes: cabinet body 100, bottom plate 200, capacitor bracket 300, capacitor 400 and charger 500. The bottom plate 200 is connected to the bottom of the cabinet body 100. The capacitor bracket 300 and the charger 500 are connected to the bottom plate 200. The capacitor 400 is arranged inside the capacitor bracket 300.

[0022] As Figure 3As shown in the figure, the capacitor bracket 300 includes: side plates 310, a back plate 320, a mounting plate 330, avoidance holes 340, mounting holes 350, and a handling opening 360. The side plates 310 are symmetrically arranged at both ends of the mounting plate 330. The side plates 310 are L-shaped structures. Avoidance holes 340 and mounting holes 350 are provided at the front ends of the side plates 310. Handling openings 360 are provided on both sides of the side plates 310. The back plate 320 is connected to the side plates 310 and the mounting plate 330. Mounting holes 350 are provided on the back plate 320. The front ends of the side plates 310 and the back plate 320 are connected to the capacitor 400 through the mounting holes 350. The mounting plate 330 is connected to the bottom plate 200.

[0023] The present utility model has the following innovative improvements compared with the traditional battery cabinet of a wind turbine:

[0024] First of all, the present utility model adds a bottom plate 200, and a capacitor 400 and a charger 500 are installed on the bottom plate 200. That is to say, on the one hand, the capacitor 400 and the charger 500 can be disassembled and assembled integrally. Only by separating and connecting the bottom plate 200 and the cabinet body 100 can the disassembly and assembly be realized, and the worker can perform the installation when the bottom plate 200 is outside, which improves the efficiency.

[0025] As Figure 4 and Figure 5 shown in the figure, secondly, the battery pack is improved. The battery pack is improved into a capacitor 400 structure, and the performance of the capacitor 400 is equivalent to that of the traditional battery pack. In this way, a large amount of space can be saved, and a charger 500 with higher efficiency and larger size can be selected to improve the performance of the overall battery cabinet. After removing the battery pack from the cabinet body, we tried to install the replaced capacitor 400 on the additional bottom plate in the cabinet in a conventional vertical manner. Since the height of the capacitor 400 is much greater than the height of the battery pack, the height of the capacitor will exceed the cabinet body. After all, it is not originally designed for the battery cabinet. Although the performance is improved in this way, there is a problem that it cannot be adapted for use.

[0026] Therefore, to solve this problem, we added a capacitor bracket 300 to the capacitor 400. The designed capacitor bracket is in the shape of a "square" with an open top surface. The side plates 310, the back plate 320, and the mounting plate 330 wrap around its two sides, the back, and the bottom respectively. In this embodiment, after laying down two groups of capacitors 400, they are placed into the capacitor bracket 300 from top to bottom. The bottom feet of the capacitor 400 and the back plate 320 of the capacitor bracket 300 are fixed through the mounting holes 350 with bolts and nuts. An avoidance hole 340 is provided at the front end of the side plate 310 of the capacitor bracket for a tool to extend in for use. Then, the capacitor 400 and the front end of the side plate 310 of the capacitor bracket 300 are fixed through the mounting holes 350 with screws. There are four handling openings 360 with square openings on the left and right sides of the side plate 310, which not only reduce the weight but also provide handling gripping points. Then, the mounting plate 330 of the assembled capacitor bracket 300 is installed on the bottom plate 200 with nuts. Finally, the bottom plate 200 is installed into the cabinet 100 with nuts.

[0027] Compared with the traditional technology, the utility model realizes an integrated installation structure of the capacitor and the charger through the bottom plate; and avoids the problem that the capacitor cannot be installed through the capacitor bracket.

[0028] The specific implementation manners of the utility model are described above, but the utility model is not limited thereto. As long as it does not depart from the purpose of the utility model, the utility model can have various variations.
