[0017] 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 implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0018] Example
[0019] See also Figure 1-3 , as shown in the figure: This embodiment is a preferred implementation of the technical solution, a double-glass polycrystalline silicon solar cell module, including a photovoltaic module 1; the photovoltaic module 1 includes a bottom plate 11, a side plate 12 fixed to the upper side edge of the bottom plate 11, a power supply compartment 14 movably arranged in the middle of the side plate 12, a photovoltaic panel 19 embedded in the upper straight section of the power supply compartment 14, an arc groove 18 opened at the edge of the upper straight section of the power supply compartment 14, an arc cover plate 15 movably arranged inside the arc groove 18, and a motor box 13 fixed to the upper part of the outer side of the side plate 12, a heat dissipation area 16 is arranged at the edge of the lower straight section of the power supply compartment 14, and a central control area 17 is arranged in the middle of the lower straight section of the power supply compartment 14;
[0020] It should be noted that: in the photovoltaic module 1 involved in the present application, its photovoltaic panel 19 adopts a double-glass polycrystalline silicon solar panel. The photovoltaic module 1 realizes the protection function of the photovoltaic module 1 by setting an arc cover 15 to shield the photovoltaic panel 19. During specific use, when the photovoltaic panel 19 is in a working state, the arc cover 15 is located in the arc groove 18 at the upper edge of the straight cut surface on the upper side of the power supply compartment 14. Conversely, when the photovoltaic panel 19 is in a non-working state, or in bad weather, the arc cover 15 is manually pulled out of the arc groove 18, and its edge is buckled in the arc groove 18 at the lower edge of the straight cut surface on the upper side of the power supply compartment 14 to limit the arc cover 15, and the arc cover 15 shields the photovoltaic panel 19 to reduce the possibility of damage. In addition, the power supply compartment 14 is controlled by the motor inside the motor box 13 to achieve angle rotation, thereby realizing the adjustment of the working angle of the photovoltaic module 1 to cater to the light in different time periods to improve the power conversion of the photovoltaic module 1.
[0021] Among them Figure 1 As shown, the edge of the bottom plate 11 is provided with a mounting hole, and the middle portion of the bottom plate 11 is hollowed out;
[0022] It should be noted that the mounting holes arranged at the edges of the bottom plate 11 are used to fix the bottom plate 11 to an external mounting structure, while the hollowing out of the middle of the bottom plate 11 is to facilitate the installation of a reinforcement structure on the bottom plate 11 .
[0023] The motor box 13 has a built-in motor, and its motor output shaft is connected to the middle of one side of the power supply compartment 14, and a shaft is fixed to the middle of the other side of the power supply compartment 14, and its shaft is connected to the bearing embedded in the middle position of the upper part of the side plate 12;
[0024] It should be noted that the motor built into the motor box 13 is used to drive the rotation of the power supply compartment 14. During the rotation of the power supply compartment 14, the shaft at the other end thereof rotates relative to the bearing to cooperate with the rotation adjustment of the power supply compartment 14. Since the rotation requirement of the power supply compartment 14 is small, the rotation angle of the output shaft of its motor is small, and a reduction mechanism can be optionally added.
[0025] Among them Figure 2 and Figure 3 As shown, the interior of the power supply compartment 14 is arranged as a cavity, and the power supply compartment 14 has a built-in power storage element, and the power storage element is connected to the central control area 17; the central control area 17 has a built-in communication unit and an execution unit, the communication unit of which is wirelessly connected to the management terminal, and the execution unit of which is connected to the power storage element and the motor;
[0026] It should be noted that: the cavity structure inside the power supply compartment 14 is used for the installation of relevant photovoltaic accessories, and the conversion and storage of the solar energy absorbed by the photovoltaic panel 19, etc. This technology is currently a relatively mature technology and is not described restrictively here. After the communication unit built into the control area 17 is wirelessly connected to the management terminal based on the Internet of Things technology, the working state, power storage and power consumption of the photovoltaic component 1 can be monitored in real time through the management terminal, and the above information will also be fed back to the screen of the central control area 17. At the same time, the management terminal can also control the execution unit operation through the communication unit, further control the changes in the working state of the motor and the power storage element, and realize remote control;
[0027] The heat dissipation area 16 is communicated with the interior of the power supply compartment 14, and a filter structure is embedded in the heat dissipation area 16;
[0028] It should be noted that the heat dissipation area 16 is a grid-like structure, which is used for air exchange and circulation between the inside of the power compartment 14 and the outside world, and assists in the dissipation of heat generated by the internal components of the power compartment 14 when working. At the same time, in order to prevent external dust and other fine particles from entering the power compartment 14, a filter structure is set to isolate dust and other substances. The filter is a relatively conventional structure at present and is not described in further detail here. In addition, the heat dissipation area 16 and the central control area 17 are both located in the lower position of the power compartment 14, which is used to protect the screen of the central control area 17, and also prevent rainwater from entering the heat dissipation area 16.
