Description

Technical Field

[0001] The utility model relates to the technical field of renewable energy, in particular to a photovoltaic device that utilizes a drawer guide mechanism to achieve high efficiency and retractability, aiming to improve the space utilization rate and flexibility of photovoltaic panels through innovative mechanical structure design, so as to meet the power generation requirements under different lighting conditions, and at the same time reduce the installation and operation and maintenance costs. Background Art

[0002] Photovoltaic power generation, as a green energy source, has great limitations in use. The energy per square meter is less than 1 kW, and the power generation efficiency of photovoltaic panels is only about 20%. Therefore, the floor area of any form of photovoltaic power generation system is quite considerable.

[0003] At present, the working scenarios of large-scale ground photovoltaics are basically limited to the ground and rooftops. For various transport vehicles in urgent need of power, due to the limited available area, it is very difficult to use photovoltaics. The problem faced is how to increase the installed capacity as much as possible on a limited installation area. Currently, the relatively feasible methods are: 1. Using high-efficiency batteries, such as gallium arsenide; 2. Reducing the vehicle weight to increase the installed solar area; 3. Using retractable or foldable photovoltaic panels to expand the light-receiving area. No matter which method is used, compared with ground and rooftop photovoltaics, the cost is extremely high.

[0004] In contrast, using retractable photovoltaics is relatively feasible. Photovoltaic panels must use rigid solar components, that is, traditional components encapsulated in glass. The weight of the glass components makes the retractable mechanism have to be designed to be bulky and complex. For example, to extend a 20-kilogram (about 200 W) photovoltaic panel parallel to the fulcrum by one meter, the bearing moment is about 200 Newton-meters. Coupled with the requirements of wind resistance, compressive resistance and safety factors, the moment should be 400 Newton-meters. Currently, the designs of retractable photovoltaic panels on the market usually use bulky frames, slide rails and bottom plate brackets, including various load-bearing rollers and supports. For example, CN113225010A discloses a structure using multi-stage pulleys and load-bearing frames, load-bearing wheels and supports; CN207399093U discloses a retractable column rod device supported under the photovoltaic panel; CN209134349U discloses a structure of a fixing plate, a support frame, a rotating block and a connecting block at the bottom end of the battery panel; CN218733987U discloses a box structure using an electric slide rod. Some previous researchers have also noticed the difficulties brought by the bulky glass-encapsulated photovoltaic components to the design of retractable photovoltaic panels. CN107640037A discloses a lightweight photovoltaic panel made of carbon fiber backplane synthesis to manufacture a retractable wing-type solar charging device for vehicles. Its retractable structure uses a chute on the inner side of the shell and the outer frame of the drawer-type retractable photovoltaic panel, which is still relatively bulky and costly.

[0005] Patents CN2019101094511 and CN2019101094526 disclose a lower plate type crystalline silicon photovoltaic module and a method for manufacturing a long-life thin photovoltaic module using cold packaging, that is, a method for manufacturing a lightweight rigid module. The photovoltaic module manufactured using the two patents has a weight of only about 20% of the traditional module with the same rigidity. The methods given in the above patents create conditions for the preparation of telescopic photovoltaic panels for vehicle use. A 4 kg (200W) photovoltaic panel prepared using the above two patents is extended parallel to the fulcrum by one meter. Its load-bearing capacity is about 50 Newton meters. In addition to the requirements of wind resistance, pressure resistance and safety factors, the maximum torque requirement is 100 Newton meters. The design requirement of this mechanical torque just falls within the load-bearing range of relatively cheap drawer rails that have been used on the market for decades and have very mature technology. Drawer rails are a mature product on the market. Contents of utility model

The moving parts of the linear drive mechanism are fixedly connected to the corresponding mobile photovoltaic panel through the connecting block. The fixed rail of the vertical drawer guide is fixedly connected to the vertical inner wall of the support frame.

[0021] After adopting such a structure, when the linear drive mechanism is started, the movable photovoltaic panel is driven to move along the preset trajectory through the connecting block. At the same time, the vertical drawer rail and the horizontal drawer rail provide guiding and supporting functions, ensuring that the movable photovoltaic panel moves smoothly without shaking during the movement. By adjusting the position of the movable photovoltaic panel, the adjustment of the sun's position at different time periods can be realized, thereby maximizing the power generation efficiency of the photovoltaic panel.

[0043] The two movable photovoltaic panels and the two sets of telescopic components are in a one-to-one correspondence relationship and can move along a preset trajectory to adjust their relative positions, thereby optimizing the area for receiving sunlight. The two movable photovoltaic panels are the first movable photovoltaic panel 310 and the second movable photovoltaic panel 320 respectively.

[0046] The structure and composition of the second telescopic component 500 are substantially the same as those of the first telescopic component 400. The second telescopic component 500 also includes a linear drive mechanism, a vertical drawer guide rail, a horizontal drawer guide rail, etc. The linear drive mechanism and the vertical drawer guide rail of the second telescopic component 500 are also fixed on the support frame 100. The horizontal drawer guide rail of the second telescopic component 500 is located above the first moving photovoltaic panel 310. The horizontal drawer guide rail is fixed to the upper side of the vertical drawer guide rail 430 of the first telescopic component 400 by bolts. The connecting block of the second telescopic component 500 is an L-shaped connecting block 510. The upper end of the L-shaped connecting block 510 extends above the upper side of the first moving photovoltaic panel 310. The second moving photovoltaic panel 320 is fixedly connected to the vertical drawer guide rail of the second telescopic component 500 through the L-shaped connecting block 510. The second moving photovoltaic panel 320 remains horizontal. The second moving photovoltaic panel 320 can move along the vertical drawer guide rail and the horizontal drawer guide rail of the second telescopic component 500 to the outside of the support frame 100. The telescopic trajectory of the first telescopic component 400 is opposite to the telescopic trajectory direction of the second telescopic component 500.

The remote control component includes a transmitting module and a receiving module. The control circuit controls the fixed photovoltaic panel 200 and the two moving photovoltaic panels to charge the battery 610. The battery 610 can also supply power to the control circuit, the linear drive mechanism of the first telescopic component 400, and the linear drive mechanism of the second telescopic component 500. The control circuit and the receiving module are both placed in the control box 620. The control box 620 is fixed to the support frame 100.

[0048] The receiving module receives the action signal sent by the transmitting module, and the receiving module sends the action signal to the control circuit. The control circuit controls the start, stop, forward, and reverse actions of the linear drive mechanisms of the first telescopic component 400 and the second telescopic component 500 according to the instructions sent by the transmitting module.

[0049] Limit switches 631 for sensing the position of the nut 413 of the induction lead screw motor 410 are respectively provided at the start and end of the telescopic trajectory of the first telescopic component 400; similarly, limit switches 631 for sensing the position of the nut of the induction lead screw motor are respectively provided at the start and end of the telescopic trajectory of the second telescopic component 500.

[0053] The difference between this embodiment and Embodiment 1 is only that the telescopic photovoltaic device manufactured using drawer rails is also arranged on the roof of a new energy vehicle, but the telescopic directions of both the first telescopic assembly and the second telescopic assembly are consistent with the length direction of the vehicle.

[0054] The above are only two implementation manners of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several variations and improvements can be made, and these should also be regarded as belonging to the protection scope of the present utility model.
