[0023] refer to Figure 4 and 6 , details the embodiment of focusing light:

[0024] A photovoltaic assembly includes the above-mentioned photovoltaic cell, and also includes a plurality of guide rods 22 fixedly connected to the upper part of a card frame 21, at least two of the guide rods 22 are slidably connected with a condenser 31, and a plurality of springs 32 are arranged between the condenser 31 and the card frame 21 and are sleeved on the outside of the corresponding guide rods 22. The condenser 31 can gather sunlight to enhance the light intensity, so that even in insufficient light, the photovoltaic cell can be charged through the light gathering effect of the condenser 31, and the condenser 31 can be fully buffered by absorbing power through the elastic deformation of the plurality of springs 32 when contracting to absorb power.

[0025] refer to Figure 2 , 5 , 7 and 8, detailed description of the embodiment of the quick installation card frame 21:

[0026] The clamping sleeve II 24 is clamped on the support frame 41. The middle part of the clamping sleeve II 24 is a circular bayonet. The upper part of the support frame 41 is a round rod. The clamping sleeve II 24 can be quickly clamped on the round rod through the opening. The clamping sleeve II 24 can rotate on the round rod of the support frame 41, so that the inclination angle of the clamping frame 21 on the clamping sleeve II 24 can be adjusted. When installing the photovoltaic cell, the inclination angle of the photovoltaic cell can be adjusted according to the use requirements, so that the photovoltaic cell has the maximum light incident angle, and can make more full use of the sun, so that the light is vertically irradiated on the photovoltaic cell for a long time. The support frame 41 is fixed. Connected to the rectangular frame 42, the rectangular frame 42 is detachably connected to the bottom plate 61, the middle part of the bottom plate 61 is rotatably connected to the limiting plate 62, the bottom plate 61 is used to be fixed to the ground or other fixed buildings, and can be quickly spread, installed and fixed over a large area. A rectangular groove coupled with the rectangular frame 42 is processed on the bottom plate 61 for placing and positioning the rectangular frame 42, and then after the bottom plate 61 is installed, the rectangular frame 42 is placed in the rectangular groove, the limiting plate 62 is rotated, and the limiting plate 62 is rotated to press down on the rectangular frame 42 to fix the rectangular frame 42. The upper part of the limiting plate 62 is an elliptical plate. The long opposite side of the limiting plate 62 can be set in the direction of the diagonal of the rectangular frame 42, and the positioning of the rectangular frame 42 can be achieved after the limiting plate 62 is rotated.

[0027] refer to Figure 5 , 6 , 7 and 8, detailed description of the embodiment of adjusting the inclination angle of the card frame 21:

[0028] The middle of the rectangular frame 42 is fixedly connected to a base frame 43, and rotating frames 51 are fixedly connected to both sides of the base frame 43. The rotating frames 51 can rotate relative to the base frame 43. Two cylinders I 52 are fixedly connected to each rotating frame 51. A sleeve rod 53 is fixedly connected to the cylinder rod of each cylinder I 52. A connecting rod 54 rotatably connected to the corresponding sleeve rod 53 is clamped on each sleeve I 23. When multiple cylinders I 52 are started, the cylinder rods of multiple cylinders I 52 drive the corresponding sleeve rods 53 to extend and retract, and the sleeve rods 53 distributed on both sides drive the two connecting rods 54 to move. The cylinder rods of multiple cylinders I 52 on both sides They extend and retract synchronously. When the cylinder rods of the multiple cylinders Ⅰ52 on one side extend, the cylinder rods of the multiple cylinders Ⅰ52 on the other side retract. The rotation of the two rotating frames 51 prevents motion interference when adjusting the tilt angle of the card frame 21, thereby ensuring the adjustment of the card frame 21. When the card frame 21 needs to be removed, the cylinder rods of the multiple cylinders Ⅰ52 on both sides are started synchronously and extended synchronously. The two connecting rods 54 rise synchronously to push the card sleeve Ⅱ24 out of the support frame 41. Then, the connection between the multiple card sleeves Ⅰ23 and the connecting rod 54 is disassembled to realize the disassembly of the card frame 21, which is convenient for the rapid disassembly, maintenance and replacement of the photovoltaic cells.

[0029] refer to Figure 8 , an embodiment of installing multiple bottom plates 61 is described in detail:

[0030] The four corners of the bottom plate 61 are processed with a quarter-circle groove, so that the bottom plate 61 can be installed by pressing down the four corners of the bottom plate 61 with gaskets and bolts.

[0031] refer to Figure 7 , an embodiment of preventing the sleeve II 24 from sliding on the support frame 41 is described in detail:

[0032] The support frame 41 is fixedly connected with a limiting slide plate for limiting the sliding of the ferrule II 24 , so that the sliding of the ferrule II 24 is limited by the limiting slide plate, thereby ensuring that the position of the ferrule II 24 is fixed.

[0033] refer to Figure 4 , an embodiment of buffering the moving condenser 31 is described in detail:

[0034] Buffer blocks are fixedly connected to the upper and lower sides of the position where the condenser 31 is connected to the guide rod 22, so as to provide buffering during the sliding process of the condenser 31 to prevent the condenser 31 from rigidly colliding with parts and causing damage to the condenser 31.

[0035] refer to Figure 4 , an embodiment in which the condenser 31 fully focuses light is described in detail:

[0036] The length of the condenser 31 is greater than the length of the card frame 21, and the width of the condenser 31 is greater than the width of the card frame 21, thereby ensuring that the condenser 31 can completely cover the photovoltaic cell, thereby fully enhancing the light and increasing the utilization rate of the photovoltaic cell for light.
