Description

Technical Field

[0001] The utility model belongs to the technical field of wind power generation equipment, and in particular relates to a wind turbine box. Background Art

[0002] A wind turbine is a system that converts the kinetic energy of wind into electrical energy. Wind energy is a clean and renewable energy source. It is not only safe and environmentally friendly, but also contains huge energy. Therefore, wind power generation is also very widespread. In a wind power generation system, a wind turbine includes a wind rotor and a generator. The wind rotor contains blades, a hub, and reinforcements. It has functions such as the blades rotating under wind power to generate electricity and the generator head rotating. Usually, this type of generator set is installed in a wind turbine box for stable protection. Since wind turbines generate heat when working, ventilation holes are usually opened in the box to ensure that airflow can circulate and achieve normal heat dissipation. However, the ventilation holes of existing wind turbine boxes are mostly directly exposed. Although airflow can be ensured for auxiliary heat dissipation, rainwater can be directly affected by wind and enter the box directly, which will have a certain impact on the equipment. In the long run, it is easy to increase the failure rate of the equipment and reduce its service life. Utility Model Content

[0011] Furthermore, a protective cover is fixedly connected to the connection between the groove and the ventilation slot.

[0012] Through the above technical solution, the protective cover can provide secondary protection for the ventilation slot, effectively ensuring the ventilation effect while isolating rainwater, thus providing safety protection for internal equipment.

A collection groove 12 is provided at the bottom of the inner wall of the groove 11, and an extended groove 12 is provided on the side wall of the collection groove 12. The drainage port 13 extending to the outside of the box body 1 can be conveniently discharged by discharging the rainwater collected in the collection tank 12; the protective frame 10 is provided with an active port 16 of the same height as the groove 11, and a filter screen 17 is arranged in the active port 16; the protective frame 10 is provided with an installation port 18 at a position corresponding to the active port 16, and a filter frame 19 is arranged in the installation port 18 through a fixing mechanism, and an adsorption layer 20 is arranged in the filter frame 19; a plurality of ventilation slots 14 connected to the active port 16 are arranged on the side wall of the groove 11, and a protective cover 15 is fixedly connected to the connection between the groove 11 and the ventilation slot 14. The protective cover 15 can provide a secondary protection effect for the ventilation slot 14, effectively ensuring the ventilation effect while isolating rainwater, and providing a safety protection effect for the internal equipment.

The setting of the groove can create a buffer space between the ventilation groove and the vent, which can prevent outdoor wind and rain from sweeping into the vent directly into the box. At the same time, rainwater entering the groove will enter the collection tank.

[0026] In the utility model, the fixing mechanism includes an inner groove 21 provided inside the upper end of the filter frame 19 and a positioning convex groove 25 located above the inner groove 21 and arranged on the inner wall of the installation opening 18. A movable block 22 and a spring 23 are respectively arranged in the inner groove 21. The lower end of the spring is fixedly connected to the bottom of the inner groove 21.

[0027] When using the wind turbine box, when rainwater is carried by wind through the vent 9 into the groove 11, the protective cover 15 can shield the ventilation groove 14 where the airflow flows, and also enable the rainwater entering the groove 11 to flow downward steadily and be concentrated in the collection groove 12, and finally be discharged through the drain port 13. The air enters the inner cavity 2 through the ventilation groove 14 and is filtered through the filter 17, which can remove some impurities in the air. At the same time, when the air passes through the adsorption layer 20, it can automatically adsorb and filter the moisture in the air, thereby reducing the impact of moisture entering the inner cavity 2 on the wind turbine equipment, and having a good protective effect. Through the setting of the fixed structure, the filter frame 19 can be easily disassembled, thereby facilitating regular cleaning or replacement of the adsorption layer 20 and the filter 17.
