Description

Technical Field

[0001] This utility model relates to the field of wind and rain protection technology for energy storage power stations, specifically to a wind and rain protection device for photovoltaic energy storage power stations. Background Technology

[0002] A photovoltaic-storage-charging integrated energy storage station is a charging facility that combines photovoltaic power generation and energy storage technology. It uses solar photovoltaic panels to generate electricity and stores the electricity for charging the power grid or electric vehicles. The core components of this type of charging station include photovoltaic modules and energy storage equipment. This system can make full use of solar energy resources and, through energy storage equipment, balance the peak and valley differences in electricity supply, thereby improving the stability of power supply.

[0003] In order to make reasonable use of solar energy resources, existing integrated photovoltaic-storage-charging stations install solar panels on the top of the station to allow direct sunlight to fully convert solar energy and supply it for storage. However, the solar panels of this structure are always exposed to the external environment. How to protect the solar panels and energy storage boxes in windy or rainy weather, thereby extending the service life of the station and ensuring that photovoltaic energy storage can still work effectively, and improving the efficiency of photovoltaic energy storage stations, is a problem that urgently needs to be considered by those skilled in the art.

[0004] Therefore, it is necessary to invent a windproof and rainproof device for photovoltaic energy storage power stations to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a wind and rain protection device for photovoltaic energy storage power stations. While protecting the photovoltaic energy storage power station, it can also improve the efficiency of photovoltaic power generation, fully supply the stored energy, and play a role in balancing peak and valley differences, thereby maximizing its safety and economy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A windproof and rainproof device for a photovoltaic energy storage power station includes an energy storage box with an open top and multiple energy storage power stations inside, and a base plate that is vertically lifted and installed inside the energy storage box. A photovoltaic panel assembly with an adjustable light-receiving angle is rotatably installed on the top of the base plate. Supports are detachably installed at the two corners of the top of the energy storage box. A frame is snapped between the bottom ends of the two supports. A protective plate that can close or open the top opening of the energy storage box is rotatably installed on one side of the frame.

[0008] When the protective plate rotates to abut against the top of the energy storage box, the protective plate completely closes the top opening of the energy storage box; when the protective plate rotates to be parallel to the support, the top opening of the energy storage box is completely open.

[0009] As a preferred embodiment of this utility model, the top ends of the two brackets are rotatably equipped with pulleys controlled by a motor, the pulleys are wound with steel wire, and the other end of the steel wire is detachably connected to the end of the protective plate away from the frame.

[0010] As a preferred embodiment of this utility model, the bottom end of the frame abuts against the top end of the energy storage box, and a hidden motor capable of driving the pulley to rotate is installed inside the frame.

[0011] As a preferred embodiment of this utility model, a fixed port is rotatably installed at each of the two corners of the top of the base plate, and a telescopic lever is slidably inserted through the top of the fixed port. The other end of the telescopic lever is rotatably connected to the two corners of one side of the bottom of the photovoltaic panel assembly, and the other side of the bottom of the photovoltaic panel assembly is rotatably connected to one side of the base plate.

[0012] As a preferred embodiment of this utility model, an entrance door is rotatably installed on one side wall of the energy storage box.

[0013] As a preferred embodiment of this utility model, protruding plates are installed on both sides of the bottom end of the protective plate, and grooves are provided on both sides of the top end of the energy storage box for the protruding plates to be engaged.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention stores the energy collected by photovoltaic (PV) panels in an energy storage power station within an energy storage box. This allows for the storage of excess generated electricity, reducing the curtailment rate of PV panels and thus improving energy storage efficiency, reducing energy consumption and costs. It is adaptable to various scenarios and can be flexibly configured. In scenarios with ample sunlight, the protective plate rotates to a parallel position with the support frame, fully opening the top of the energy storage box. By driving the PV panels to rotate on the top of the base plate, the PV panels adaptively adjust their angle of illumination according to changes in the sunlight angle, maximizing energy collection. In windy or rainy weather, the protective plate rotates to a position where it contacts the top of the energy storage box, completely sealing the top opening and preventing the internal PV panels from being directly exposed to wind and rain. This protects both the PV panels and the energy storage box from wind and rain, extending the lifespan of the power station. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] This utility model provides, for example Figure 1-Figure 3 The photovoltaic energy storage power station windproof and rainproof device shown includes an energy storage box 1 with an open top and multiple energy storage power stations inside, and a base plate 10 that is vertically lifted and installed inside the energy storage box 1. A photovoltaic panel assembly 7 with an adjustable light-receiving angle is rotatably installed on the top of the base plate 10. Supports 3 are detachably installed at the two corners of the top of the energy storage box 1. A frame 5 is snapped between the bottom ends of the two supports 3. A protective plate 6 with an adjustable opening at the top of the energy storage box 1 is rotatably installed on one side of the frame 5.

[0023] When the protective plate 6 rotates to abut against the top of the energy storage box 1, the protective plate 6 completely seals the top opening of the energy storage box 1; when the protective plate 6 rotates to be parallel to the bracket 3, the top opening of the energy storage box 1 is completely open.

[0024] Two brackets 3 are rotatably fitted with pulleys 4 controlled by motors at their top ends. The pulleys 4 are wound with steel wires, and the other end of the steel wires is detachably connected to the end of the protective plate 6 away from the frame 5. The bottom end of the frame 5 abuts against the top end of the energy storage box 1, and a hidden motor is installed inside the frame 5 to drive the pulleys 4 to rotate. The hidden motor drives the pulleys 4 to rotate, which in turn pulls the protective plate 6 through the steel wire to achieve the closing and opening of the protective plate 6, that is, to complete the closing and opening of the opening at the top of the energy storage box 1. The protective plate 6 is made of acrylic material, which has high transparency, excellent weather resistance, high surface hardness and surface gloss, as well as good high temperature performance, meeting the required protection and light transmission functions.

[0025] Fixed ports 11 are rotatably installed at the two corners of the top of the base plate 10. A telescopic lever 12 is slidably inserted through the top of the fixed port 11. The other end of the telescopic lever 12 is rotatably connected to the two corners of the bottom side of the photovoltaic panel 7. The other side of the bottom of the photovoltaic panel 7 is rotatably connected to one side of the base plate 10. The telescopic lever 12 actively extends and retracts, thereby changing the height of one end of the photovoltaic panel 7, that is, driving the photovoltaic panel 7 to rotate above the base plate 10 to adapt to the adjustment of the illumination angle and the light receiving angle.

[0026] An entrance door 2 is rotatably installed on one side wall of the energy storage box 1 to facilitate staff access for maintenance.

[0027] The protective plate 6 has protruding plates 9 installed on both sides of its bottom end. The top of the energy storage box 1 has grooves 8 on both sides of its top end for the protruding plates 9 to be engaged. When the protective plate 6 contacts the top of the energy storage box 1, the protruding plates 9 are fully engaged in the grooves 8 to prevent the protective plate 6 from moving.

[0028] In this invention, the energy collected by the photovoltaic panel module 7 is stored in the energy storage power station inside the energy storage box 1. This allows for the storage of excess power generation, reducing the curtailment rate of the photovoltaic panel module 7, thereby improving the utilization efficiency of energy storage, reducing energy consumption and costs, and adapting to different scenarios with flexible configuration. In scenarios with sufficient sunlight, the protective plate 6 rotates to a position parallel to the support 3, at which point the top opening of the energy storage box 1 is fully open. By driving the photovoltaic panel module 7 to rotate on the top of the base plate 10, the photovoltaic panel module 7 adaptively adjusts its angle of light reception according to changes in the angle of sunlight, thereby maximizing energy collection. In windy and rainy weather, the protective plate 6 rotates to a position where it abuts against the top of the energy storage box 1, thereby completely sealing the top opening of the energy storage box 1. This prevents the internal photovoltaic panel module 7 from being directly exposed to wind and rain, and avoids the photovoltaic panel module 7 being constantly exposed to the external environment. In other words, the photovoltaic panel module 7 and the energy storage box 1 are protected by the protective plate 6 in windy and rainy weather, thereby improving the service life of the power station.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
