Description

Side plate connection structure of combined transformer box for wind power generation

technical field

The utility model relates to a power generation device, in particular to a box body of a combined transformer for wind power generation.

Background technique

Wind power generation equipment is a device that provides human beings with usable energy by doing work through air flow, and can provide human beings with green and environmentally friendly new energy sources. Wind power generation requires high wind power. The equipment is generally built in beaches, deserts, grasslands and other places where there are few people and high wind speed. Therefore, the wind power generation equipment itself is required to have high environmental adaptability. Among them, the protection level of the outer box of the wind power combined transformer is required to reach IP54, so as to have a reliable sealing system, and its doors, windows and vents are all Measures shall be provided to prevent dust, animals and insects from entering, and prevent seepage and rainwater leakage. The inner wall and partition of the box shall be made of highly anti-corrosion metal materials. The inclination angle of the top cover of the box must be greater than 3°, and a defensive sealing cover and rain-proof eaves are required.

At present, the protection level of the outer box of wind power combined transformers in the industry is difficult to meet this requirement, especially the side plate structure adopted on the side of the box is connected to the channel steel base to fix the entire box. , its structure is shown in Figure 1, the side plate 1 and the channel steel base 2 are provided with an inner flange for matching and fixed together by bolt locking, so that at the junction of the side plate 1 and the channel steel base 2, There will be a slight gap, and the gap directly leads to the electrical components inside the box. In rainy, snowy and sandy weather, the gap may seep into water, snow or sand, causing damage to the electrical components in the box. .

Contents of the invention

In view of the above problems, the utility model provides an improved connection structure for the side plate and the channel steel base of the wind power combined transformer box, so as to effectively prevent rainwater, snow or wind sand from entering the box.

The technical scheme that the utility model adopts for solving its technical problem is:

The side plate connection structure of the combined wind power transformer box includes a side plate and a channel steel base. The inner wall of the side plate is welded and fixed with a welded plate with a folded edge, and the folded edge of the welded plate is combined with the upper side of the channel steel base. The side plate covers the junction of the welded plate and the channel steel base.

The beneficial effects of the utility model are: the utility model adopts a welding plate as an intermediate connecting piece to fix the side plate and the channel steel base, so that the side plate can extend downwards and cover the connection gap directly leading to the inside of the box body , In this way, rainwater, snow or dust will not easily enter the box through the gap, and then damage the electrical components, so that the electrical components in the box are well protected, and the protection level meets the requirements.

Description of drawings

Further explanation is carried out below in conjunction with accompanying drawing and specific embodiment:

Fig. 1 is the connection structure schematic diagram of side plate and channel steel base in the prior art;

Fig. 2 is a schematic diagram of the connection structure between the side plate and the channel steel base of the utility model.

Detailed ways

As shown in Figure 2, the side plate connection structure of the wind power combined transformer box provided by the utility model includes a side plate 1 and a channel steel base 2, wherein the inner wall of the side plate 1 is welded and fixed to the welded plate 3, and the lower end of the welded plate 3 An inwardly folded right-angle flange 31 is provided, and the position of the flange is just connected and fixed to the upper side of the channel steel base 2, and the fixing method can preferably be realized by using bolts 4, and the bolts 4 penetrate the flange 31 and the channel steel base 2 The upper side 21 of the upper side of the box, and locked together; in this way, the tight joint between the flange 31 and the upper side 21 of the channel steel base 2 is directly connected to the gap of the electrical components inside the box, in order to achieve a good For protection effect, in the utility model, the side plate 1 is extended downward to cover the junction of the flange 31 of the welded plate 3 and the channel steel base 2 on the outside, so as to become a structure for blocking and protecting. When in use, there is a turning point from the covering portion extending downwards from the side plate 1 to the joint gap between the flange 31 and the channel steel base 2, so that rainwater, snow or dust will enter the flange 31 and the channel steel base 2 It is necessary to go up a certain distance along the covering part of the side plate 1. In the natural environment, this situation is difficult to happen. In order to achieve a better protection effect, the covering part of the side plate 1 is preferably the same as the channel steel The outer side of the base 2 is closely fitted, so that the gap is minimized and the protective effect is better.

It can be seen that the utility model uses a relatively simple structure, so that the electrical components in the box are well protected, and the protection level meets the use requirements. It is a technical solution that is very suitable for popularization and application.
