[0028] The convenient mechanism includes a docking strip 5 and a matching opening 6. The docking strip 5 is fixed to the bottom of the reflector 4, and matching openings 6 corresponding to the position of the docking strip 5 are opened on all sides of the support shell 1. The matching openings 6 are slidably connected to the docking strip 5. Through the docking of the docking strip 5 and the matching openings 6, the reflector 4 and the support shell 1 can be quickly connected.

[0029] The convenient mechanism also includes a fixed box 7, a guide groove 8, a force applying rod 9, a compression spring 10, a movable bar 11 and a through-carrying rod 12. The fixed box 7 is fixed on all sides of the support shell 1. A guide groove 8 is opened on one side of the fixed box 7. The guide groove 8 is connected to the inner side of the fixed box 7.

The movable bar 11 is slidably connected to the inner side of the fixed box 7. A compression spring 10 is fixed to the bottom of the movable bar 11. One end of the compression spring 10 is fixed to the inner side of the fixed box 7. Two through-carrying rods 12 are fixed to the top of the movable bar 11. The through-carrying rod 12 is assembled and connected with the docking bar 5. When the force applying rod 9 is pulled, the movement trajectory of the force applying rod 9 can be guided by the setting of the guide groove 8.

[0030] The bottom of the docking strip 5 is provided with two anti-slip grooves 13 corresponding to the position of the through-carrying rod 12. The anti-slip grooves 13 are slidably connected to the through-carrying rod 12. Through the setting of the through-carrying rod 12 and the anti-slip grooves 13, the docking strip 5 is conveniently limited in the matching opening 6.

[0031] The bottom of the supporting shell 1 is provided with heat dissipation fins, and the heat dissipation of the supporting shell 1 is facilitated by the provision of the heat dissipation fins.

[0032] Example 2

[0033] Embodiment 1 is further optimized, specifically, as Figure 5As shown, the auxiliary mechanism includes a bearing plate 14, a rotating column 15, a supporting foot 16, a track groove 17, a threaded rod 18, a force-applying horizontal plate 19 and a transmission rod 20.

Because the threaded rod 18 is threadedly connected to the moving block, the moving block is slidably connected to the track groove 17, and the moving block is fixed to the force-applying horizontal plate 19, the moving block can drive the force-applying horizontal plate 19 to move along the inner side of the track groove 17, so that the force-applying horizontal plate 19 pushes the support shell 1 to rotate through the transfer rod 20, thereby realizing the adjustment of the angle of the photovoltaic panel 2.

[0034] From the above, we can know that:

[0035] The utility model aims at the technical problem that although the power generation efficiency of solar photovoltaic panels can be improved by using reflective panels, since the reflective panels are fixed on the support plates and are generally made of reflective materials, when the reflective panels are damaged and need to be replaced, the operation is relatively cumbersome; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0036] When the reflector 4 needs to be replaced, the force-applying rod 9 is pulled downward, so that the force-applying rod 9 drives the movable bar 11 to move along the inner side of the fixing box 7, so that the compression spring 10 is squeezed and contracted, and then the movable bar 11 drives the through-carrying rod 12 to move downward until the through-carrying rod 12 is separated from the anti-slip groove 13, and then the reflector 4 is pulled so that the docking strip 5 is separated from the mating opening 6;

[0037] Then replace the new reflector 4 so that the docking strip 5 is inserted into the matching opening 6. At this time, the force rod 9 is released, and the elastic force generated by the compression spring 10 pushes the movable strip 11 to move and reset, so that the movable strip 11 drives the penetrating carrying rod 12 to be inserted into the anti-slip groove 13, thereby achieving fixed limit of the docking strip 5 and completing the quick replacement of the reflector 4.

[0038] In the prior art, the CSP system is combined with the photovoltaic panel 2: This technical solution combines the CSP system with the photovoltaic system to share the same solar energy collection system. By adding a collector to the photovoltaic module, the photothermal and photoelectric effects of sunlight can be utilized at the same time to improve the power generation efficiency of the system.

[0039] Application of thermal storage system: Thermal storage technology plays an important role in the solar-thermal synergy system. Using thermal storage tanks or molten salt storage technology, excess thermal energy can be stored when there is sufficient sunlight, and continue to provide heat or electricity at night or under low radiation conditions. This technical solution can achieve a stable supply of energy and improve the reliability and flexibility of the system.

[0040] Combined heat and power system: The combination of the solar-thermal synergy system and the combined heat and power system can realize the joint supply of electricity and heat energy. The combined heat and power system meets the building's electricity demand and heating, hot water and other thermal energy needs through solar-thermal power generation and heat energy extraction. This technical solution can improve energy utilization efficiency, reduce energy waste, and has relatively significant energy-saving and environmental protection effects.

[0041] At the same time, in the prior art, a transparent shell and a copper-graphene-paraffin composite phase change material are used. The copper-graphene-paraffin composite phase change material has excellent thermal conductivity and light absorption, and can effectively utilize the heat generated by the photovoltaic panel and the light energy passing through the transparent shell.

[0042] In the prior art, during the day, sunlight shines on the surface of the system. The photovoltaic power generation system directly performs photovoltaic power generation and generates heat. At the same time, the phase change material absorbs heat and absorbs solar energy through the transparent insulation layer, and the temperature rises. At this time, the phase change material stores thermal energy and works together with the heat dissipation fins to form a temperature gradient on the surface of the thermoelectric sheet, thereby driving the temperature difference power generation system to generate electricity. During the day, the two systems operate simultaneously to achieve efficient energy utilization. At night, due to the lack of sunlight, the photovoltaic power generation system cannot work. However, the phase change material has accumulated a large amount of thermal energy during the day, so that the temperature difference power generation system can continue to operate at night, achieving continuous and stable power output. The two methods of solar photovoltaic power generation and solar thermal power generation are organically combined, and solar energy is directly used for photovoltaic power generation. The solar energy is also concentrated and converted into thermal energy through the concentrator, which further improves the utilization efficiency of solar energy.

[0043] In the prior art, phase change energy storage materials are used as heat sources to absorb and store heat energy converted from solar energy during the day, and release heat at night for the thermoelectric power generation part to continue working. This heat storage method not only ensures the efficient use of solar energy during the day, but also realizes continuous power generation at night, prolongs the power generation time, and improves the overall power generation efficiency. It reduces the space volume and simplifies the system design. Copper graphene paraffin composite phase change materials are used to replace thermal energy conversion equipment and thermal energy collection equipment. The design structure of photovoltaic panels, transparent shells, copper graphene paraffin composite phase change materials, thermoelectric power generation sheets, heat dissipation fins, etc.

[0045] 1. The utility model adopts a convenient structural design to make it easy for the support shell 1 and the reflector 4 to be quickly disassembled and assembled when the reflector 4 is damaged, thereby speeding up the work efficiency and improving the high efficiency of the device.

[0046] 2. The utility model uses the structural design of the auxiliary mechanism to enable the device to adjust the angle and orientation of the photovoltaic panel 2 to improve the efficiency of the photovoltaic panel 2 in receiving sunlight, thereby achieving good use effect.
