[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy and distributes electric energy. Substations in some special areas, such as desert areas, are often located in areas with strong winds and sand, so the buildings and equipment in the station area are often eroded by wind and sand, causing great damage to the buildings and equipment in the station area.

[0003] For this reason, we design a windproof sofa power supply structure here. Utility Model Content

[0008] Compared with the prior art, the utility model provides a windproof sofa charging structure, which has the following beneficial effects:

[0009] The array device used for wind and sand protection and power generation in substations is implemented by setting a row of vertical axis fans on the substation fence. When the wind and sand pass through the spiral blades of the fans, the fans can absorb the kinetic energy of the wind and sand and reduce its flow rate to reduce the invasion of the wind and sand on the substation. At the same time, the generated electricity can be used by electrical equipment in the station area. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1 and Figure 2In this embodiment: a windproof sofa power generation structure includes a vertical axis fan 1, the vertical axis fan 1 includes a vertical central axis 1-1, two spiral blades 1-2 are installed on the side of the central axis 1-1, the blade cross-section of the spiral blade 1-2 is arc-shaped, the use of the spiral blade 1-2 can increase the contact area between the blade and the wind and sand, the two spiral blades 1-2 are distributed in a ring array with the central axis of the central axis 1-1, and six pairs of reinforcing rods 1-3 distributed at equal intervals up and down are arranged on the side of the central axis 1-1, each pair of reinforcing rods 1-3 is respectively fixedly installed between the inner edges of the two spiral blades 1-2 and the central axis 1-1, and the spiral blades 1-2 are fixedly fixed on the central axis 1-1 alone. In an environment with strong wind and sand, the spiral blades 1-2 may be bent and deformed, or even directly broken. By setting the reinforcing rods 1-3, the spiral blades 1-2 can be reinforced to prevent the spiral blades 1-2 from deforming, so that the spiral blades 1-2 can withstand greater wind and sand. The bottom end of the central axis 1-1 is provided with a hairpin The rotor of the motor 1-4 and the generator 1-4 is fixed to the bottom end of the central shaft 1-1. When the wind and sand pass through the spiral blades 1-2, the central shaft 1-1 can be driven to rotate, so that the central shaft 1-1 drives the rotor of the generator 1-4 to rotate, so as to absorb the kinetic energy of the wind and sand, thereby reducing the flow rate of the wind and sand, so as to reduce the erosion of the buildings in the substation by the wind and sand. At the same time, the electric energy converted from the kinetic energy of the wind and sand can be supplied to the equipment in the substation. A column 1-5 is installed at the bottom of the generator 1-4, and a base 1-6 is installed at the bottom of the column 1-5. A circle of mounting holes is reserved on the base 1-6. When installing the vertical axis fan 1, it is only necessary to fix the base 1-6 to the installation area with bolts. Multiple vertical axis fans 1 are installed side by side on the top of the fence 2. Multiple vertical axis fans 1 are arranged side by side to block the wind and sand blowing towards the substation in a large area. The spacing between two adjacent vertical axis fans 1 is equal. The specific spacing between the two vertical axis fans 1 is determined according to the actual situation to ensure that the vertical axis fans 1 do not interfere with each other.

[0015] The working principle and use process of the utility model are as follows: when sandstorms come, the sandstorms will first pass through a row of vertical axis fans 1 arranged on the top of the fence 2, and the sandstorms will knock down the spiral blades 1-2, and the spiral blades 1-2 will drive the central shaft 1-1 to rotate, so that the central shaft 1-1 drives the rotor of the generator 1-4 to rotate. At this time, part of the kinetic energy of the sandstorms will be absorbed, and the flow rate of the sandstorms will be greatly reduced, thereby reducing the erosion of the substation by the sandstorms. At the same time, the electric energy generated by the generator 1-4 can be used by the equipment in the substation.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
