Description

Technical Field

[0001] The present invention relates to the field of photovoltaic power generation, and in particular to a photovoltaic power supply device and method with adjustable photovoltaic panels. Background Art

[0002] Photovoltaic panel components are power generation devices that generate direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon).

[0003] The solar AC power generation system is composed of solar panels, charge controllers, inverters and batteries, while the solar DC power generation system does not include inverters. In order for the solar power generation system to provide sufficient power for the load, it is necessary to reasonably select various components based on the power of the electrical appliances.

[0004] Since the sun is in a different position in each time period, the direction of sunlight is also different. A photovoltaic panel adjustment device is disclosed through search, with announcement number: CN115149894A;

[0005] The adjustment of photovoltaic panels is usually to adjust the pitch angle and direction, but the main adjustment components of the current photovoltaic panel adjustment device are relatively large in size, and the installation position occupied during installation is also relatively large, which leads to relatively recurring problems during maintenance;

[0006] Secondly, after the photovoltaic panels have been stationary for a certain period of time, a certain amount of dust will adhere to the surface, causing the contact surface of the photovoltaic panels to be exposed to sunlight. Most of the existing ones do not have corresponding cleaning mechanisms, including the invention provided above. The few devices equipped with cleaning mechanisms are only cleaned once at a specific time and cannot be cleaned synchronously while adjusting. Of course, this can be achieved through servos and programming, but the cost of this method is relatively high and not practical. In addition, this type of power supply equipment needs to draw power from the storage battery of the photovoltaic panel, resulting in a waste of electricity, and the service life of this type of equipment under wind and sun is relatively low.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0049] For example, see Figures 1 to 11 , a photovoltaic power supply device with adjustable photovoltaic panels, comprising a photovoltaic panel body 1, a bracket 101 is fixed at the bottom of the photovoltaic panel body 1, and further comprising:

[0050] A mounting plate 2, on which a support member 16 is fixed, a transmission disc 15 is arranged on the top of the support member 16, a limiting ring 1502 is coaxially fixed on the transmission disc 15, the transmission disc 15 is rotatably connected to a limiting groove 1601 provided on the top of the support member 16 through the limiting ring 1502, an adjustment component is installed on the transmission disc 15, and the adjustment component is connected to the bracket 101;

[0051] A transmission assembly is installed in the support member 16, and the transmission assembly is connected to the adjustment assembly;

[0052] A driving assembly, the driving assembly is mounted on the mounting plate 2, and the driving assembly is connected to the transmission disc 15;

[0053] An energy storage component is installed on the mounting plate 2 , and the energy storage component is connected to the photovoltaic panel body 1 and the driving component.

[0054] In an embodiment of the present invention, the electric energy generated when the photovoltaic panel body 1 is working is stored in the energy storage component, and the energy storage component is used to supply power to the driving component and other equipment requiring energy. When the driving component is working, the transmission disk 15 is driven to rotate, and when the transmission disk 15 rotates, the transmission component is driven to work, and the adjustment component is driven to work through the transmission component. Through the rotation of the adjustment component and the transmission disk 15, the photovoltaic panel body 1 is driven to change the angle of the component while rotating, so that the photovoltaic panel body 1 is in the optimal working direction and pitch angle all day long.

[0055] The adjustment assembly includes a screw rod 6 installed on the transmission disk 15, and a threaded sleeve 601 threadedly matched with the screw rod 6 is sleeved on the screw rod 6. A transmission plate 9 is hinged on the threaded sleeve 601, and the transmission plate 9 is hinged to the bracket 101 at one end away from the threaded sleeve 601. A follower assembly is installed on one side of the screw rod 6, and the follower assembly connects the threaded sleeve 601 and the transmission assembly.

[0056] In the embodiment of the present invention, the follower assembly is driven to work by the transmission assembly, and the threaded sleeve 601 is driven to rotate when the follower assembly is working. When the threaded sleeve 601 rotates, it is vertically raised / lowered by cooperating with the thread of the screw rod 6. When the threaded sleeve 601 rises / falls, the photovoltaic panel body 1 is driven to flip through the transmission plate 9. The flipping is used to adjust the pitch angle of the photovoltaic panel body 1 so that the working surface of the photovoltaic panel body 1 is adjusted to the optimal working angle.

[0057] Among them, the principle of adjusting the pitch angle of the photovoltaic panel body 1 through the transmission plate 9 is similar to the opening and closing principle of an umbrella. This adjustment method has higher stability because the screw rod 6 and the threaded sleeve 601, the transmission plate 9, and the bracket 101 are always in a triangular state, and the triangle has the characteristic of stability. In addition, this adjustment method has a simple structure. The simpler the structure in design, the lower the possibility of failure.

[0058] The follower assembly includes a No. 1 transmission rod 5 that penetrates the transmission plate 15 and is rotatably connected thereto, a transmission sleeve 501 is slidably sleeved on the No. 1 transmission rod 5, a plurality of transmission bars are equidistantly fixed on the No. 1 transmission rod 5, and the transmission bars are slidably matched with transmission grooves provided on the inner wall of the transmission sleeve 501;

[0059] A follower plate 702 is rotatably mounted on the transmission sleeve 501, and the follower plate 702 is rotatably connected to the threaded sleeve 601. The first transmission rod 5 and the screw rod 6 are rotatably connected via a stabilizing plate 7, and two guide rods 701 are fixed at the bottom of the stabilizing plate 7, and the guide rods 701 are slidably matched with the follower plate 702;

[0060] The transmission sleeve 501 and the threaded sleeve 601 are also connected via a gear set 8, and the gear set 8 includes two mutually meshing gears, and the two gears are coaxially fixed to the transmission sleeve 501 and the threaded sleeve 601 respectively;

[0061] The first transmission rod 5 is connected to the transmission assembly.

[0062] In the embodiment of the present invention, when the transmission assembly is working, the No. 1 transmission rod 5 is driven to rotate. When the No. 1 transmission rod 5 rotates, the transmission sleeve 501 is driven to rotate along with the No. 1 transmission rod 5 through the cooperation between the transmission bar and the transmission groove, so that the No. 1 transmission rod 5 drives the transmission sleeve 501 to rotate synchronously while the No. 1 transmission rod 5 rotates, and the transmission sleeve 501 can slide along the axial direction of the No. 1 transmission rod 5, that is, vertically slide;

[0063] When the transmission sleeve 501 rotates, the gear set 8 drives the threaded sleeve 601 to rotate. When the threaded sleeve 601 rotates, the threaded sleeve 601 is driven to rise / fall by the threaded cooperation with the screw rod 6. When the threaded sleeve 601 rises / falls, the follower plate 702 drives the transmission sleeve 501 to follow the rise / fall, thereby achieving that the threaded sleeve 601 will not be separated from the transmission between the transmission sleeve 501 when rising / falling to any height. In addition, the angle of the photovoltaic panel body 1 is adjusted by threaded transmission, and the adjustment accuracy is relatively high, and the required driving force is relatively small. Because the power of the driving component is based on the energy storage component, and the energy storage component stores the electric energy generated by the photovoltaic panel body 1, the energy storage component can store more electricity by adopting a smaller power driving device;

[0064] The sliding fit between the follower plate 702 and the guide rod 701 is to improve the stability during the above movement.

[0065] The transmission assembly includes a third gear 18 coaxially fixed to the end of the first transmission rod 5, and the third gear 18 cooperates with a second gear ring 1801 fixed to the inner wall of the support member 16;

[0066] A first gear 17 is coaxially fixed to the third gear 18 , and the first gear 17 is meshed with a second gear 1702 rotatably mounted on the bottom of the transmission plate 15 , and the second gear 1702 cooperates with a gear ring 1701 fixed to the inner wall of the support member 16 .

[0067] In the embodiment of the present invention, when the driving assembly is working, the transmission disc 15 is driven to rotate, and when the transmission disc 15 rotates, the first transmission rod 5, the screw rod 6, the photovoltaic panel body 1 and other related components are correspondingly driven to rotate;

[0068] The first transmission rod 5 and the lead screw 6 are both installed at the eccentric position of the transmission disc 15, so when the transmission disc 15 rotates, the first transmission rod 5 and the lead screw 6 both rotate around the center of the transmission disc 15. When the first transmission rod 5 rotates around the center of the transmission disc 15, it drives the third gear 18 to rotate synchronously. When the third gear 18 rotates, it drives the third gear 18 and the first transmission rod 5 to rotate through the engagement with the second gear ring 1801. In short, the first transmission rod 5 and the third gear 18 rotate around the center of the transmission disc 15 while rotating on their own.

[0069] Among them, the second gear ring 1801 is not a full tooth. It can be seen from the figure that when the third gear 18 is disengaged from the second gear ring 1801, the second gear 1702 is engaged with the gear ring 1701, and the second gear 1702 is driven to rotate with the rotation after the engagement. When the second gear 1702 rotates, it drives the first gear 17, the third gear 18, and the first transmission rod 5 to rotate in the opposite direction by engaging with the first gear 17 (the third gear 18 and the second gear ring 1801 are already disengaged at this time);

[0070] The effect achieved by the above state is: the driving assembly drives the transmission disc 15 to rotate continuously in one direction, and when the transmission disc 15 rotates, the No. 1 transmission rod 5 is driven to rotate, and after the transmission disc 15 rotates 180°, the No. 1 transmission rod 5 is driven to rotate in the opposite direction without changing the direction of rotation of the transmission disc 15, and the rotation of the No. 1 transmission rod 5 corresponds to the adjustment of the pitch angle of the photovoltaic panel body 1;

[0071] Furthermore, in the morning, the angle of the photovoltaic panel body 1 is about 160°, and with subsequent adjustments, it is finally adjusted to about 120°. When the photovoltaic panel body 1 is at 120°, the sun has set, and the photovoltaic panel body 1 is not working during this time period. At this time, the photovoltaic panel body 1 has also rotated 180°, and when the subsequent rotation is 180°, the pitch angle of the photovoltaic panel body 1 will be adjusted from about 120° to about 160°, and then the photovoltaic panel body 1 will be readjusted to 160° when the sun goes up the next day, and the process is repeated to achieve automatic angle and pitch angle adjustment of the photovoltaic panel body 1.

[0072] The driving assembly includes a motor bracket 14 fixed on the mounting plate 2 , a motor 1401 is fixed on the motor bracket 14 , a driving gear 1402 is coaxially fixed on the output shaft of the motor 1401 , and the driving gear 1402 is meshed with a driven gear ring 1501 coaxially fixed on the transmission disc 15 .

[0073] In the embodiment of the present invention, when the motor 1401 is working, the output shaft thereof drives the driving gear 1402 to rotate, and when the driving gear 1402 rotates, the driving gear 1402 drives the transmission plate 15 to rotate through the meshing with the driven gear ring 1501;

[0074] The driving gear 1402 in the present invention is a small gear, and the driven gear ring 1501 is a large gear. The small gear drives the large gear to reduce speed and increase torque, so that the torque required by the motor 1401 is smaller.

[0075] The energy storage assembly includes a storage battery 1101 fixed on the mounting plate 2 . The storage battery 1101 is coaxially arranged with the transmission disc 15 . The storage battery 1101 is connected to the photovoltaic panel body 1 via a wire 11 . The storage battery 1101 is electrically connected to the motor 1401 .

[0076] In the embodiment of the present invention, the electric energy generated by the photovoltaic panel body 1 during operation is transmitted to the storage battery 1101 through the wire 11 for storage, and the storage battery 1101 supplies power to the motor 1401 and required equipment.

[0077] A protective shell 3 is also installed on the mounting plate 2 . The protective shell 3 is sleeved on the outside of the storage battery 1101 and the support member 16 . A baffle is provided on the protective shell 3 . The baffle is coaxially arranged with the protective shell 3 .

[0078] In the embodiment of the present invention, there are two implementation modes, as follows:

[0079] Embodiment 1: The protective shell 3 is rotatably mounted on the mounting plate 2, the storage battery 1101 is fixed to the inner wall of the protective shell 3, and the protective shell 3 rotates with the transmission disk 15. The protective shell 3 is fixed to the transmission disk 15 through a connecting rod. When the transmission disk 15 rotates, the storage battery 1101 and the protective shell 3 rotate with the transmission disk 15. At this time, the wire 11 will not be entangled due to the rotation of the transmission disk 15;

[0080] In the second embodiment, the protective shell 3 and the storage battery 1101 are fixed on the mounting plate 2, and the wire 11 is rotatably connected to the photovoltaic panel body 1. The rotatable connection prevents the transmission disk 15 from getting tangled when rotating. This method is more complicated to implement, and the first embodiment is preferred.

[0081] The photovoltaic panel body 1 is also rotatably mounted with a scraper 4, and a plurality of scraper strips 401 are fixed on the scraper 4 facing the photovoltaic panel body 1, and a plurality of nozzles 402 are also arranged on the scraper strips 401 facing the photovoltaic panel body 1, and the scraper 4 is connected to the screw rod 6 via a transmission member;

[0082] Four storage boxes 13 are fixed on the back of the photovoltaic panel body 1. The four storage boxes 13 are fixed by connecting blocks 1302, and the four storage boxes 13 are also connected by a No. 1 connecting pipe 1303 and a No. 2 connecting pipe 1304. One of the storage boxes 13 is connected to the scraper 4 through a conveying pipe 1301.

[0083] An air pump 12 is also fixed to the back of the photovoltaic panel body 1 , and the output end of the storage box 13 is connected to the storage box 13 .

[0084] In the embodiment of the present invention, when the screw rod 6 rotates, the scraper 4 is driven to rotate through the transmission member, and the surface of the photovoltaic panel body 1 is cleaned through the scraper bar 401 when the scraper 4 rotates, and when the storage box 13 works, air is pumped into the storage box 13, and the cleaning liquid in the storage box 13 is transported to the scraper 4 through the delivery pipe 1301 through the air pressure in the storage box 13, and is sprayed out through the nozzle 402. When the scraper 4 rotates, the cleaning liquid is sprayed through the scraper bar 401 and the nozzle 402 to clean the surface of the photovoltaic panel body 1;

[0085] In another implementation of this embodiment, a delivery pump is fixed on the back of the photovoltaic panel body 1, and the input end of the delivery pump is connected to the storage box 13, and the output end of the delivery pump is connected to the storage box 13. The effect achieved is the same as that of the above-mentioned implementation, which can be selected according to actual production and is not specifically limited by the present invention.

[0086] The transmission member includes a transmission frame 1004 rotatably mounted on the threaded sleeve 601, and a transmission shaft 1002 is also rotatably mounted on the transmission frame 1004. Universal joints 1001 are coaxially fixed to the transmission shaft 1002 and the rotating shaft of the scraper 4, and the two universal joints 1001 are connected by a second transmission rod 10;

[0087] Two relatively arranged incomplete bevel gears 1005 are coaxially fixed on the threaded sleeve 601 , and a full bevel gear 1003 is coaxially fixed on the transmission shaft 1002 . The full bevel gear 1003 is located between the two incomplete bevel gears 1005 and cooperates with the two incomplete bevel gears 1005 .

[0088] In the embodiment of the present invention, when the threaded sleeve 601 rotates, it drives the two incomplete bevel gears 1005, and the rotation of the incomplete bevel gears 1005 drives the full bevel gear 1003 to rotate back and forth. When the full bevel gear 1003 rotates back and forth, it drives the transmission shaft 1002 to rotate synchronously, so that when the transmission shaft 1002 rotates, the scraper 4 is driven to reciprocate through the universal joint 1001 and the second transmission rod 10;

[0089] The transmission frame 1004 is used to limit the transmission shaft 1002 so that the transmission shaft 1002 can rise / fall along with the threaded sleeve 601;

[0090] The effect produced is: each rotation of the threaded sleeve 601 corresponds to an angle adjustment of the photovoltaic panel body 1, and each rotation of the threaded sleeve 601 drives the scraper 4 to reciprocate to achieve a cleaning of the photovoltaic panel body 1. Because the photovoltaic panel body 1 will maintain a certain direction and a pitch angle for a certain period of time, during this process, a certain amount of dust or mud may adhere to the photovoltaic panel body 1 to affect the electrical energy generated by the photovoltaic panel body 1 when it is working. The pitch angle adjustment and direction adjustment of the present invention are synchronized. Through this embodiment, the surface of the photovoltaic panel body 1 can be cleaned once during each adjustment, so that the photovoltaic panel body 1 always maintains the best working direction, the best pitch angle, and a clean surface.

[0091] Further description of the two incomplete bevel gears 1005 driving the full bevel gear 1003 to reciprocate, for the convenience of description, the two incomplete bevel gears 1005 are named as the first wheel and the second wheel, the first wheel and the second wheel rotate synchronously, and the toothed part of the first wheel is on the left side, and the toothed part of the second wheel is on the right side, and the first wheel and the second wheel are a complete bevel gear when they overlap;

[0092] When the toothed portion of the number one wheel meshes with the full bevel gear 1003, the full bevel gear 1003 is driven to rotate, and when the number two wheel meshes with the full bevel gear 1003, the full bevel gear 1003 is driven to rotate in the opposite direction, and at the same time, the number one wheel is disengaged from the full bevel gear 1003;

[0093] It should also be noted that the second transmission rod 10 includes a transmission cylinder and a transmission rod, the transmission cylinder and the transmission cylinder slide axially relative to each other, and the structure is the same as the first transmission rod 5 and the transmission sleeve 501.

[0094] The present invention also provides a photovoltaic power supply method with adjustable photovoltaic panels, using the photovoltaic power supply device with adjustable photovoltaic panels, comprising the following steps:
