Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation devices, and more specifically, to an outdoor portable photovoltaic power generation device. Background Art

[0002] Photovoltaic power generation systems are based on the photovoltaic effect of semiconductor materials, efficiently converting solar energy into electricity. They offer advantages such as high reliability, long service life, environmental friendliness, and the ability to generate electricity both independently and in conjunction with the grid. They can generate electricity locally without the need for fuel or transmission lines.

[0003] Since outdoor use requires portability, the solar panels of photovoltaic power generation devices are relatively small. However, the power generation efficiency of a solar panel is closely related to the amount of sunlight it receives. A smaller area means less light energy is captured, which directly limits the power generation efficiency of the device. In addition, some photovoltaic power generation devices lack tracking devices, resulting in low power generation efficiency. If manual intervention is required, the operation is relatively cumbersome. In addition, in the wild, debris such as leaves may be blown down by the wind and block the solar panels. If not cleaned in time, the power generation efficiency will be reduced. This further reduces the power generation efficiency of portable photovoltaic power generation devices with weaker power generation capabilities. Summary of the Invention

[0004] The present invention aims to overcome the defects of the prior art and provide an outdoor portable photovoltaic power generation device.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a photovoltaic power generation device, including a box body, a control box, a mounting frame, a connecting plate hinged to the mounting frame, an intermediate mounting plate fixedly connected to the connecting plate, a first mounting plate hinged to the intermediate mounting plate on one side, a side ridge fixedly connected to the intermediate mounting plate, and a second mounting plate hinged to the side ridge on one side; the mounting frame is hinged to a support rod, and a plurality of support blocks cooperating with the support rods are fixed to the back of the intermediate mounting plate; the intermediate mounting plate, the first mounting plate, and the second mounting plate all have mounting grooves, and solar panels are installed in the mounting grooves.

[0006] Furthermore, the control box is fixed in the box body.

[0007] Furthermore, the mounting bracket is mounted on the box body and can rotate within the box body.

[0008] Furthermore, the support blocks are arranged in a row with equal intervals, and a support slot into which the end of the support rod is embedded is formed between two adjacent support blocks.

[0009] Furthermore, the cross section of the support block is triangular.

[0010] Thereby, the support rod can realize support, and the angle of the middle mounting plate can be adjusted.

[0011] Furthermore, a strip-shaped convex plate is fixed on the back of the second mounting plate, and a rotatable first rotating plate and a rotatable second rotating plate are installed on the back of the middle mounting plate. The first rotating plate can be used to support the first mounting plate, and the second rotating plate can be used to support the second mounting plate.

[0012] Furthermore, there are two of each of the first rotating plates and the second rotating plates.

[0013] Thereby, better support for the first mounting plate and the second mounting plate can be achieved.

[0014] Furthermore, when there is no external force, the relative position between the first rotating plate and the intermediate mounting plate will not change.

[0015] Furthermore, when there is no external force, the relative position between the second rotating plate and the intermediate mounting plate will not change.

[0016] Therefore, the first rotating plate and the second rotating plate are mounted on the middle mounting plate by using a device having a damping structure, so that the first rotating plate and the second rotating plate will not rotate at will.

[0017] Furthermore, there are two strip-shaped convex plates.

[0018] Therefore, the second rotating plate can provide better support for the two strip-shaped convex plates.

[0019] Furthermore, when the middle mounting plate, the first mounting plate and the second mounting plate are unfolded, the back of the middle mounting plate, the back of the first mounting plate and the surface of the strip convex plate are flush, the first rotating plate abuts the back of the first mounting plate, and the second rotating plate abuts the surface of the strip convex plate.

[0020] Furthermore, an electric winding device is installed in the box body, and the mounting frame includes two hinged seats, a connecting rod, and a rotating rod hinged with the support rod; a fan unit is hingedly connected to the front of the connecting plate, and a first semicircular ring and a second semicircular ring are respectively fixed on both sides of the fan unit, a third semicircular ring is fixed at the connecting plate, a through-hole is provided at the connecting rod, and a fourth semicircular ring is fixed at the rotating rod, an elastic pull rope is connected between the first semicircular ring and the third semicircular ring, a connecting pull rope passing through the through-hole is connected between the second semicircular ring and the fourth semicircular ring, the connecting pull rope has a circular portion passed by the connecting pull rope, and the winding pull rope is connected between the electric winding device and the circular portion; a guide hole is provided at the rotating rod, and a guide column is provided in the guide hole, and an abutment plate that abuts the box body is fixed to the bottom end of the guide column, and a spring passed by the guide column is provided between the abutment plate and the rotating rod; a limiting plate that can abut the fan unit is fixed at the connecting plate.

[0021] Furthermore, the connecting rod connects the two hinged seats.

[0022] Furthermore, one end of the rotating rod is fixedly connected to the connecting rod, and the other end is hinged to the supporting rod.

[0023] Furthermore, when the electric winding device reels in the winding rope, the mounting bracket can be rotated only after the fan unit abuts against the limit plate and the winding continues.

[0024] Therefore, when the electric winding device reels in the rope, it first drives the fan unit to rotate. When the fan unit abuts against the limiting plate and cannot rotate, it further drives the mounting frame to rotate.

[0025] Furthermore, the heat dissipation fan includes a fan housing having an air inlet hole and an air blowing opening.

[0026] Furthermore, a heating unit is provided in the fan housing.

[0027] This enables faster drying when the solar panel is dried using the fan unit.

[0028] Furthermore, there are two of each of the guide hole, the guide column, the abutment plate and the spring.

[0029] Furthermore, the lower surface of the abutment plate has an anti-slip pad or an anti-slip coating.

[0030] Therefore, due to the friction between the abutting plate and the box body, the mounting bracket will not be easily rotated.

[0031] Furthermore, the photovoltaic power generation device can be in an expanded state and a stored state. In the expanded state, the support rod and the support block cooperate to support the intermediate mounting plate, the first rotating plate abuts the back of the first mounting plate, and the second rotating plate abuts the strip-shaped convex plate; in the stored state, the intermediate mounting plate, the first mounting plate and the second mounting plate are all stored in the box body, and the first mounting plate is located between the intermediate mounting plate and the second mounting plate.

[0032] Furthermore, in the deployed state, the fan unit can be swung while the mounting frame is kept stationary by taking in and releasing the rope of the electric winding device; in the deployed state, the fan unit can be abutted against the limit plate while the mounting frame is rotated by taking in and releasing the rope of the electric winding device; in the stored state, the fan unit can be swung while the mounting frame is kept stationary by taking in and releasing the rope of the electric winding device.

[0033] Furthermore, the connecting plate is hinged to two hinge seats, each hinge seat is connected to a slider, the box body has two arc-shaped slide grooves, the two sliders cooperate with the two arc-shaped slide grooves, and each slider is embedded in one of the arc-shaped slide grooves.

[0034] Therefore, the cooperation between the slider and the arc-shaped slide groove makes the rotation of the mounting bracket more stable.

[0035] Furthermore, a rotating shaft is fixed to the connecting rod, and the rotating shaft is installed on the box body through a bearing unit.

[0036] Thereby, the rotation of the rotating frame is made more stable.

[0037] Furthermore, a control unit, a battery and a Bluetooth unit are installed in the control box, and a charging socket is provided at the control box.

[0038] Thus, the photovoltaic power generation device can realize Bluetooth communication and can be conveniently charged using a charging socket, and the battery can supply power to the control unit, the Bluetooth unit, the electric winding device and the fan unit.

[0039] Furthermore, the cross section of the box body is U-shaped, and the box body includes a base plate and two side plates connected to the base plate; the side plates are provided with strip-shaped slots.

[0040] Furthermore, it also includes a box cover, and both sides of the box cover are provided with bar-shaped insertion rails that cooperate with the bar-shaped slots.

[0041] Therefore, the box cover and the box body can better cooperate to accommodate the middle mounting plate, the first mounting plate and the second mounting plate.

[0042] Beneficial effects:

[0043] 1. The photovoltaic power generation device of the present application can accommodate various mounting plates in the box when stored, and can be unfolded and stably supported when used outdoors, thereby facilitating portability and use.

[0044] 2. The photovoltaic power generation device of the present application has a rotatable mounting frame, so that the solar panel has a light-chasing function, thereby achieving efficient power generation.

[0045] 3. The photovoltaic power generation device of the present application can actively clear obstructions such as fallen leaves to avoid a reduction in power generation efficiency due to obstruction of solar panels.

[0046] 4. The photovoltaic power generation device of the present application, after being stored, if the photovoltaic power generation device is wet, can be dried in the stored state. BRIEF DESCRIPTION OF THE DRAWINGS

An abutment plate 3.6 is fixed at the bottom end of the guide post 3.5, which abuts the box body 1. A spring is located between the abutment plate 3.6 and the rotating rod 3.3, through which the guide post 3.5 passes. A limiting plate 4.2 is fixed to the connecting plate 4, which can abut the fan unit 14. There are two of each of the guide hole, guide post 3.5, abutment plate 3.6, and spring. The lower surface of the abutment plate 3.6 has an anti-slip pad or anti-slip coating. The photovoltaic power generation device can be in an expanded state and a stored state. In the expanded state, the support rod 9 cooperates with the support block 5.1 to support the intermediate mounting plate 5, the first rotating plate 11 abuts the back of the first mounting plate 6, and the second rotating plate 12 abuts the strip convex plate 8.1; in the stored state, the intermediate mounting plate 5, the first mounting plate 6 and the second mounting plate 8 are all stored in the box body 1, and the first mounting plate 6 is located between the intermediate mounting plate 5 and the second mounting plate 8.In the deployed state, the fan unit 14 can be swung while the mounting frame is kept stationary by taking in and releasing the rope of the electric winding device 13; in the deployed state, the fan unit 14 can be brought into contact with the limit plate 4.2 while the mounting frame is rotated by taking in the rope of the electric winding device 13; in the stored state, the fan unit 14 can be swung while the mounting frame is kept stationary by taking in and releasing the rope of the electric winding device 13.

[0065] The connecting plate 4 is hinged to two hinged seats 3.1, and each hinged seat 3.1 is connected to a slider 3.7. The box body 1 has two arc-shaped slide grooves 1.3. The two sliders 3.7 cooperate with the two arc-shaped slide grooves 1.3, and each slider 3.7 is embedded in one of the arc-shaped slide grooves 1.3. A rotating shaft is fixed to the connecting rod 3.2, and the rotating shaft is installed on the box body 1 through a bearing unit; a control unit, a battery and a Bluetooth unit are installed in the control box 2, and the control box 2 has a charging socket. The cross-section of the box body 1 is U-shaped, and the box body 1 includes a base plate 1.1 and two side plates 1.2 connected to the base plate 1.1; the side plates 1.2 have a strip slot 1.4. In addition, the photovoltaic power generation device of the present application also includes a box cover (not shown in the figure), and both sides of the box cover have strip rails that cooperate with the strip slots 1.4.

[0066] Working principle: The photovoltaic power generation device of the present application, in the storage state, the middle mounting plate, the first mounting plate and the second mounting plate can be stored in the box body, which is convenient for carrying. When used outdoors, the second mounting plate and the first mounting plate can be unfolded and supported by the first rotating plate and the second rotating plate, and the middle mounting plate can be lifted to a suitable angle according to the height of the sun's sunshine and supported by the support rod. When in use, the middle mounting plate can be oriented toward the angle of sunlight (for example, in the morning, so that the middle mounting plate is oriented toward a position close to the east), and then, for example, every hour, the middle mounting plate can be adjusted to a certain angle using an electric winding device. And in this process, every 5 minutes (or other times), the electric winding device can be used to drive the fan unit to rotate from the side close to the first semicircular ring toward the direction of the limit plate, and the fan unit blows air during the rotation, so that if there are leaves blocking the solar panel, they can be blown away in time. Because the spring forces the abutment plate against the base surface of the housing, the mounting bracket cannot be easily rotated. Consequently, when the electric winding device reels in the cord, the winding cord pulls on the annular portion, which in turn pulls on the connecting cord, driving the fan unit to rotate toward the stop plate. When the electric winding device releases the cord, the elastic cord forces the fan unit to return to its original position. To adjust the mounting bracket's angle, the electric winding device reels in the cord. During this process, the fan unit first abuts the stop plate. As the electric winding device continues to reel in the cord, the connecting cord drives the mounting bracket to overcome the friction of the abutment plate and rotate toward the electric winding device (the mounting bracket only needs to rotate a small angle at set intervals).

[0067] And after use, if the photovoltaic power generation device is wetted by rain and not stored in time, after storage, since the solar panel is installed in the installation groove, there is a gap between the middle installation plate, the first installation plate and the second installation plate. At this time, the fan unit can be used to blow air, and the angle of the fan unit can also be adjusted by the electric winding device, so as to achieve rapid drying of the photovoltaic power generation device.

[0068] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
