[0002] Solar power generation refers to a power generation method that directly converts light energy into electrical energy without going through a thermal process. It includes photovoltaic power generation, photochemical power generation, photoinduction power generation and photobiological power generation. Photovoltaic power generation is a direct power generation method that uses solar-grade semiconductor electronic devices to effectively absorb solar radiation energy and convert it into electrical energy. It is the mainstream of solar power generation today.

[0003] The Chinese utility model patent with publication number CN208569405U discloses a new energy lifting device, including a fixed plate, a rotating shaft, a positioning gear, a support rod, a fixed cavity, a bolt, an arc pressure plate and a screw rod. The fixed plate is fixed on the rotating shaft, and a solar panel is installed on the upper end surface of the fixed plate. The rotating shaft is installed on the fixed block, the positioning gear is fixed on the right end of the rotating shaft, and the support rod is installed in the sleeve. This design achieves the effect of easy and simple adjustment of the position of the solar panel. The fixed cavity is installed on the upper end surface of the base, the bolt is installed in the right end of the fixed cavity, the arc pressure plate is arranged in the fixed cavity, the electric telescopic rod is fixed on the left end of the arc pressure plate, and the screw rod is fixed on the lower end surface of the fixed cavity; the utility model achieves the effect of saving time and effort in installing and fixing the electric telescopic rod.

[0004] However, the above utility model still has some shortcomings:

[0005] 1. During the use of the above utility model, the solar panel is installed on the upper end surface of the fixed plate, and the fixed plate is installed in the fixed block by rotating the shaft. When the positioning gear drives the shaft and the fixed plate to rotate and adjust the angle, a gap will be generated between the fixed plate and the placement box.

[0039] See also Figure 1-5 The present invention provides a technical solution: a lifting device for solar power generation, including a protective box 1, a top of the protective box 1 is provided with a protective cover 2 that is opposite to each other, a mounting groove 3 is provided on the protective cover 2, a flip assembly 8 is arranged in the mounting groove 3, the flip assembly 8 is fixedly installed on the side wall of the protective box 1, and the flip assembly 8 and the protective cover 2 are fixedly connected.

[0040] like Figure 1 As shown, a notch is provided at the joint of the two opposing protective covers 2, and the two notches correspond to each other and can fit together, so that multiple curved gaps can be formed when the two protective covers 2 are combined, which can effectively prevent rainwater from entering the protective box 1 through the gap between the opposing protective covers 2;

[0041] A mounting groove 3 is provided on the side wall of the protective cover 2 away from the notch, and a trapezoidal block 4 is arranged in the mounting groove 3. The trapezoidal block 4 is fixedly connected to the top of the side wall of the protective box 1, and its lower end is close to the mounting box 81, so that when rainwater falls into the mounting groove 3, it can flow out of the mounting groove 3 along the slope of the trapezoidal block 4 to avoid entering the protective box 1 through the gap; or the top of the protective box 1 at the mounting groove 3 is made inclined, which can also prevent rainwater from entering the protective box 1 through the gap between the protective cover 2 and the protective box 1.

[0042] Furthermore, a lifting assembly 6 is installed at the bottom of the protective box 1, and the lifting assembly 6 is connected to the flip assembly 8 through the linkage assembly 7. The lifting assembly 6 controls the solar panel 5 to rise and drives the flip assembly 8 through the linkage assembly 7 to control the protective cover 2 to flip open.

[0044] Furthermore, the plate portion of the rack plate 71 is fixedly connected to the bottom of the mounting plate 64, a fixing plate 72 is oppositely connected to the inner wall of the protective box 1, and gear 1 73 is rotatably connected between the fixing plates 72 through a rotating member; a placement groove 75 is opened on the inner wall of the protective box 1, and gear 2 74 is rotatably installed in the placement groove 75 through a rotating member.

[0045] like Figure 3 As shown, the left and right inner walls of the protection box 1 are fixedly connected with oppositely arranged fixing plates 72, and a rotating member (such as a rotating rod, a fixing rod and other columnar objects) is rotatably connected between the fixing plates 72, and the gear 1 73 is sleeved on the side wall on which the rotating member is installed. Similarly, the gear 2 74 is rotatably installed in the placement groove 75 (the placement groove 75 is provided on the side wall where the protection box 1 and the installation box 81 are connected, that is, the placement groove 75 connects the protection box 1 and the installation box 81); the left and right side walls of the gear 1 73 are respectively meshed with the gear 2 74 and the toothed part of the rack plate 71;

[0046] When the rack plate 71 moves in the vertical direction, the chain 82 can be driven by the gear 1 73 and the gear 2 74 to transmit the power.

[0047] Furthermore, the lifting assembly 6 includes a lifting motor 61, which is installed at the inner bottom of the protective box 1. The output shaft end of the lifting motor 61 is connected to a threaded rod 62, a threaded sleeve 63 is screwed on the side wall of the threaded rod 62, and the top of the threaded sleeve 63 is fixedly connected to a mounting plate 64.

[0048] Furthermore, a movable groove 66 is opened on the inner wall of the protective box 1, and a limit strip 65 is fixedly connected to the side wall of the mounting plate 64, and the limit strip 65 is snapped into the movable groove 66; a rotating assembly 15 is installed on the top of the mounting plate 64, and the solar cell panel 5 is installed on the rotating assembly 15.

[0049] Specifically, the setting of the limit bar 65 and the moving groove 66 limits the installation plate 64 from rotating in the horizontal direction, ensuring that when the threaded rod 62 rotates, the threaded sleeve 63 can drive the installation plate 64 and the rack plate 71 to move in the vertical direction.

[0050] Furthermore, the flip assembly 8 includes an installation box 81, which is fixedly installed on the outer wall of the protective box 1. A chain 82 is arranged inside the installation box 81, and the outer side of the chain 82 is transmission connected to the gear 2 74; the inner side of the chain 82 is transmission connected to two sprockets 83, and the sprockets 83 are mounted on the side walls of the connecting rod 84. The two ends of the connecting rod 84 located at the top pass through the side walls of the installation box 81 and are fixedly connected to the protective cover 2, and the two ends of the connecting rod 84 located at the bottom are rotatably connected to the inner wall of the installation box 81.

[0051] Specifically, the connecting rod 84 located at the top and the installation box 81 are rotationally connected. When the chain 82 is transmitting, the sprocket 83 located at the top rotates to drive the corresponding connecting rod 84 and the protective cover 2 to rotate, and the sprocket 83 located at the bottom has a tensioning effect on the chain 82, that is, to ensure that the chain 82 is taut for transmission.

[0052] Furthermore, the rotating assembly 15 includes a rotating motor 151, which is installed on the top of the mounting plate 64. The output shaft end of the rotating motor 151 is connected to a rotating rod 152, and the rotating rod 152 is obliquely installed with a connecting plate 153. The solar panel 5 is installed on the top of the connecting plate 153.

[0053] Specifically, the solar panel 5 is installed on the top of the inclined connecting plate 153, so that the inclined solar panel 5 can receive more light, thereby improving the utilization efficiency of sunlight; the rotating motor 151 controls the rotating rod 152 to drive the connecting plate 153 and the solar panel 5 to rotate, which can cater to the sunlight according to the sunrise time, thereby ensuring that the solar panel 5 can receive more light, thereby further improving the utilization efficiency of sunlight.

[0054] Furthermore, a dustproof plate 9 is rotatably connected to the side wall of the mounting plate 64 , and a plurality of heat dissipation holes 10 are provided on the top of the dustproof plate 9 .

[0055] Specifically, the setting of the dustproof plate 9 allows the mounting plate 64 to provide dust protection for the internal structure of the protective box 1 when the solar panel 5 is lifted out of the protective box 1, thereby reducing the entry of dust into the protective box 1 and preventing larger foreign objects from entering the protective box 1. The setting of the heat dissipation holes 10 can ensure the heat dissipation of the internal components of the protective box 1. In addition, the dustproof plate 9 can also be rotated to take out the internal components of the protective box 1.

[0056] Furthermore, a regulating fan 11 and several batteries 12 are installed at the inner bottom of the protective box 1, and a temperature sensor 13 and a humidity sensor 14 are installed at the bottom of the mounting plate 64; the lifting motor 61, the rotating motor 151, the regulating fan 11, the temperature sensor 13 and the humidity sensor 14 are all connected to the battery 12 through lines; the temperature sensor 13 and the humidity sensor 14 are all connected to the regulating fan 11 through lines.

[0057] Specifically, the solar panel 5 is connected to the battery 12 through a line, so that the electric energy converted from solar energy can be stored in the battery 12, and the battery 12 is also connected to external electrical appliances through a line to provide electric energy;

[0058] The temperature sensor 13 detects the temperature inside the protective box 1. When the temperature exceeds the set value, the regulating fan 11 is controlled to blow out cold air for cooling; when the temperature is lower than the set value, the regulating fan 11 is controlled to blow out hot air to protect the normal operation of the internal components; the humidity sensor 14 detects the humidity inside the protective box 1, and controls the regulating fan 11 to blow out cold air or hot air according to the detected temperature of the temperature sensor 13.

[0059] The working principle and use process of the present invention: After the present invention is installed, the opposing protective covers 2 are fitted on the top of the protective box 1, covering the entire protective box 1 below to prevent rain and snow;

[0060] When the sky clears, the lifting motor 61 controls the threaded rod 62 to rotate, so that the threaded sleeve 63 drives the mounting plate 64, the rotating assembly 15 and the solar panel 5 to move upward. In this process, the mounting plate 64 synchronously drives the rack plate 71 to move upward, and drives the chain 82 through the transmission of the gear 1 73 and the gear 2 74. The sprocket 83 drives the corresponding connecting rod 84 and the protective cover 2 to gradually flip outward, ensuring that the solar panel 5 will not be restricted by the protective cover 2 during the upward movement and receive the sunlight.

[0061] As the sunshine time increases, the rotating motor 151 controls the rotating rod 152 to drive the connecting plate 153 and the solar panel 5 to rotate gradually, so as to ensure that the solar panel 5 can receive more light.
