Detailed ways

The utility model will be further described in detail below in conjunction with specific embodiments.

An intelligent photovoltaic power generation brick for buildings, as a green building material that integrates power generation and heat collection, has multiple functions such as wall sound insulation, noise reduction, heat preservation, and heat insulation.

The structure of the power generation brick 1 is shown in Figure 2 and Figure 3, including a rectangular parallelepiped brick body 11, a number of photovoltaic cells 12 are laid on the front of the brick body 11 facing outwards, and a photovoltaic unit composed of a plurality of photovoltaic cells, In the utility model, the two ends of each photovoltaic cell are provided with bypass diodes 15 in parallel, which can bypass the photovoltaic cell when the photovoltaic cell is blocked, so as to prevent hot spots on the module and prevent It affects the power generation of other photovoltaic cells and greatly increases the power generation of the components; the back of the brick body 11 facing the building is fixedly provided with a terminal 14 connected to the photovoltaic cells, which is more convenient for plugging in, which facilitates the output of direct current to the grid and saves energy. The cables of traditional components are eliminated, the construction speed is improved, and the construction cost is greatly reduced.

There is a collection tank 17 inside the brick body, and the collection tank is set corresponding to the photovoltaic cells. The back of the brick body is provided with a via hole connecting the collection tank and the outside, and a heat collection pipeline 3 communicating with the indoor heat collector 2 is installed on the via hole. . The setting of the collection tank can collect the heat generated by the photovoltaic module during power generation in winter, and transfer it to the indoor heat collector for recycling through the heat collection pipeline. While generating heat, it also increases power generation.

In the present utility model, the photovoltaic unit and the brick body are connected through the ventilation grid 16, and the ventilation grid forms a channel connecting the brick collection tank and the outdoor. The setting of the ventilation grid allows air to enter the collection tank through this channel. In summer, the outdoor cold air enters the collection tank through the ventilation grid on the side of the collection tank. Due to the internal and external pressure difference, the back of the photovoltaic panel is quickly The heat is taken away to achieve the function of cooling the photovoltaic module, increasing the power generation of the photovoltaic module and prolonging the service life; at the same time, the heat taken away enters the indoor collector and is used to heat cold water for washing with domestic water. Of course, it can also be used Through the temperature sensing device, the excess heat can be discharged directly to the outside.

In order to improve the heat collection capacity of the collection tank, several protrusions 13 are arranged on the rear end surface of the collection tank corresponding to the back of the brick body. The shape of the protrusions is set as a pyramid, which can prolong the flow time of the air and greatly increase the cross-sectional area of the air flow , to achieve the purpose of strengthening the heat collection capacity of the collection tank.

The utility model can be used alone as an independent power supply unit, and can be spliced and used according to the area of the building wall. When used in splicing, magnets can be respectively embedded inside the side walls around the brick body to ensure the stability of the connection between bricks.

When the utility model is manufactured, the battery slices are firstly welded, and the battery slices are selected first. In the process, the color of the battery slices must be consistent, and the appearance problems such as edge collapse and missing corners of the battery slices cannot occur; when welding, each battery slice is connected in parallel. Weld a diode; after installing the adsorption magnet on the side wall of the collection tank, install the ventilation grid around the top; then connect the cables of the solar panel to the prefabricated terminals of the collection tank, and finally install the packaged power generation unit to the top of the collecting tank, ensuring a tight fit.

When building a wall, assemble the Qin bricks according to the building area. After the wall is completed, connect the terminals to the power grid through cables, and connect the heat collection pipeline of the power generation bricks to the indoor heat collector, as shown in Figure 3 shown. After the installation is completed, turn on the heat collector, and the air will pass through the ventilation grid and enter the collection tank. When the sun shines on the surface of the battery sheet, the battery sheet will start to generate electricity, and a certain amount of heat will be generated while generating electricity. The hot gas will pass through the pyramids one by one. The bumps flow in the collection tank, and enter the heat collector along the heat collection pipeline, as shown by the arrow in Figure 3, and then deploy and use it in different seasons through the temperature sensing and control device of the heat collector.
