In one embodiment of the present utility model, as shown in fig. 1-2, a concentrating device is provided that combines solar photovoltaic power generation and heat generation, comprising a concentrator 100, an energy storage mechanism 200, and a plurality of monocrystalline silicon panels 300.
The concentrator 100 is for concentrating sunlight.
The energy storage mechanism 200 is connected to the condenser 100, and the heat collected by the condenser 100 is transferred to the energy storage mechanism 200 and then stored by the energy storage mechanism 200.
The monocrystalline silicon panel 300 is disposed on the surface of the condenser 100, for realizing solar photovoltaic power generation and storing electric energy.
Specifically, the single crystal silicon panel 300 is attached to the surface of the condenser 100.
In another embodiment of the present utility model, the single crystal silicon cell panel 300 is disposed on the condensing surface of the condenser 100. The monocrystalline silicon panel 300 is a solar cell using high-purity monocrystalline silicon as a raw material, and has the functions of photovoltaic power generation and electric energy storage. When sunlight irradiates the condenser 100, the single crystal silicon panel 300 positioned on the condensing surface receives solar energy to perform photovoltaic power generation.
In another embodiment of the present utility model, as shown in fig. 1, the concentrator body 100 includes a concave pan 110 and a heat collecting assembly 120. The heat collecting assembly 120 is connected with the pan body 110, and the heat collecting assembly 120 is also connected with the energy storage mechanism 200. The concave inner side surface of the pan body 110 is covered with a mirror surface for reflecting sunlight, so that the concave inner side surface of the pan body 110 faces the sunlight to form a condensing surface. Sunlight is reflected by the mirror surface of the collecting surface of the pan body 110 and collected to the heat collecting assembly 120. The single crystal silicon cell plate 300 is disposed on the surface of the mirror surface. When the sunlight irradiates on the inner side surface of the recess of the pan body 110, the mirror surface reflects the sunlight, so that the sunlight is concentrated and finally irradiated on the heat collecting assembly 120. Specifically, the larger the inner surface area of the concave portion of the pan body 110, the more sunlight can be emitted to the ground by the concentrator body 100, and thus the more heat can be collected by the heat collecting assembly 120.
Further, as shown in fig. 3, the monocrystalline silicon battery plates 300 are arranged in a spiral shape, so that more monocrystalline silicon battery plates 110 are arranged on the limited surface area of the pot body 110 as much as possible, thereby increasing the power generation amount of the utility model, and simultaneously, the appearance of the pot body 110 is more regular and beautiful.
In another embodiment of the present utility model, as shown in fig. 4, the single crystal silicon cell plates 300 are arranged in a plurality of concentric circles having different diameters from each other.
In another embodiment of the present utility model, as shown in fig. 2, the concentrator body 100 includes a recessed pan 110, a heat collecting assembly 120, and a mounting plate 400. The heat collecting assembly 120 is connected with the pan body 110, and the heat collecting assembly 120 is also connected with the energy storage mechanism 200. The concave inner side surface of the pan body 110 is covered with a mirror surface for reflecting sunlight, so that the concave inner side surface of the pan body 110 faces the sunlight to form a condensing surface. Sunlight is reflected by the mirror surface of the collecting surface of the pan body 110 and collected to the heat collecting assembly 120. The mounting plate 400 is connected to the outer side surface of the pot 110. The single crystal silicon cell plate 300 is disposed on a side of the mounting plate 400 adjacent to the condensing surface of the condenser 100. Specifically, the mounting plate 400 may be connected to the top end of the outer side surface of the pot body 110, and may also be disposed around the edge of the pot body 110, where the monocrystalline silicon battery plate 300 mounted on the mounting plate 400 performs photovoltaic power generation on the premise of not affecting the heat collecting effect of the pot body 110.
In another embodiment of the present utility model, as shown in fig. 1-2, the single crystal silicon cell plates 300 are each in a square sheet shape, and the single crystal silicon cell plates 300 are arranged at equal intervals. A certain space is left between each single crystal silicon cell plate 300, which is beneficial to heat dissipation of the single crystal silicon cell plates 300.
In another embodiment of the present utility model, as shown in fig. 1-2, the heat collecting assembly 120 includes a plurality of heat conductive rods 121 and a light collecting block 122. One end of the heat conducting rod 121 is connected to the pan body 110. The light condensing block 122 is connected to the other end of the heat conducting rod 121. The light-gathering block 122 is connected to the energy storage mechanism 200. The heat conducting rod 121 mainly serves to connect the condensing block 122 of the pan body 110. By adjusting the orientation of each heat conducting rod 121, the light condensing block 122 may be located at a converging point of the sunlight, so that the light condensing block 122 may fully obtain the sunlight reflected by the pan body 110. The heat conducting rod 121 is made of a material with good heat conducting performance. In this embodiment, the heat conducting rod 121 is made of silicon carbide. Therefore, the heat conducting rod 121 has good heat conducting performance, and heat generated by sunlight irradiated on the heat conducting rod 121 can be well transferred to the light condensing block 122, so that heat acquired by the light condensing block 122 is increased to a greater extent. Specifically, the light-gathering block 122 is made of a composite material of paraffin and expanded graphite, and has a strong heat storage capacity.
In another embodiment of the present utility model, as shown in fig. 2, the energy storage mechanism 200 includes a heat storage tub 210. The heat storage barrel 210 is connected with the condensing block 122, and the heat storage barrel 210 is used for storing heat collected by the condensing block 122. It should be noted that, how the heat storage barrel 210 stores the heat of the sunlight is already a mature technology. Those skilled in the art can directly store the solar heat and convert the solar heat into other heat for storage, and those skilled in the art should know and understand the method of storing solar heat and the related structure of storing heat in the heat storage barrel 210 and how the heat storage barrel 210 is connected to the condensing block 122, so the details will not be described herein.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
