Description

Technical Field

[0001] The utility model relates to the technical field of solar panels, in particular to a self-cleaning bracket for a solar panel. Background Art

[0002] Solar panels are devices that use the photovoltaic effect of semiconductor materials under light conditions to directly convert solar energy into electrical energy. When solar panels are placed outdoors for a long time, they will inevitably accumulate dust, fallen leaves, and even plastic bags. In northern areas, they are also easily covered with snow. Dust or accumulation will reduce light transmittance or partially block it, which will seriously reduce power generation efficiency at the least, and cause local overheating or even burn solar panel components at the worst. In order to keep the surface of solar panels clean, general staff will clean them regularly.

[0003] For example, the public document with application number 202322201310.7 discloses a self-cleaning bracket for solar panels. The utility model opens an upper support rod inside the rainwater storage chamber, and then arranges a rainwater receiving plate, a T-shaped metal transmission pipe, a transmission metal branch pipe, etc. to transfer the collected rainwater to the inside of the liquid extraction pipe for storage, thereby making full use of the internal space of the rainwater storage chamber. While increasing the quality of the rainwater storage chamber, it ensures the stability of the rainwater storage chamber when supported, and can store rainwater, thereby fully improving the utilization rate of the rainwater storage chamber. Then, in conjunction with the flushing liquid temporary storage pipe and the spray gun arranged on the top of the solar panel and the drive of the pump body, automatic control is realized to regularly flush the upper surface of the solar panel, thereby realizing the function of automatically cleaning the solar panel of the bracket. However, if the water stains on the surface of the solar panel are not wiped dry in time by flushing with water, the self-cleaning bracket of the solar panel will leave a large number of water stains and dust marks on the surface of the solar panel, which is difficult to clean, and only one side of the panel can be cleaned, while the other side of the panel cannot be fully cleaned.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a solar panel self-cleaning bracket is proposed. Utility Model Content

[0011] Preferably, an insert block is provided at the lower interior of the slot, and a universal ball is rotatably provided on the surface of the insert block close to the inner surface of the slot, and the opposite side of the insert block is fixedly connected to the left and right ends of the solar photovoltaic panel.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a screw rod, a guide rod, a driving motor, a pulley, an adjustment plate and a soft cleaning roller. The driving motor drives the rear screw rod to rotate. Under the transmission of the pulley using a synchronous belt, the front screw rod rotates synchronously.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 2 As shown, a solar panel self-cleaning bracket comprises a mounting frame 1, wherein protrusions 2 are fixedly mounted on the upper and lower ends of the front and rear sides and the left and right sides of the surface of the mounting frame 1, and screw rods 3 are rotatably arranged between the upper and lower corresponding protrusions 2 on the right side through bearings, and guide rods 4 are fixedly arranged between the upper and lower corresponding protrusions 2 on the left side, the upper end of the screw rod 3 on the right rear side of the mounting frame 1 passes through the protrusion 2 and a driving motor 5 is arranged, the lower end of the screw rod 3 passes through the protrusion 2 and a pulley 501 is fixedly mounted, and the front and rear pulleys 501 are connected by a synchronous belt, and the surfaces of the screw rod 3 and the guide rod 4 are provided with adjustment plates 6, and the adjustment plates 6 are threadedly connected to the screw rod 3 and are slidably connected to the guide rod 4, and soft cleaning rollers 7 are rotatably arranged at the middle parts of the opposite ends of the two adjustment plates 6 on the same side of the mounting frame 1 through bearings, a solar photovoltaic panel 8 is arranged in the middle part of the mounting frame 1, and the soft cleaning roller 7 is fitted on the front and rear side surfaces of the solar photovoltaic panel 8.

[0023] Furthermore, the pulleys 501 are respectively assembled with the bottom ends of the front and rear screw rods 3 and connected through a synchronous belt. The driving motor 5 only needs to drive one screw rod 3 to make the two screw rods 3 rotate synchronously, thus reducing the waste of energy consumption of the motor drive components.

[0024] Furthermore, the adjustment plate 6 is connected to the soft cleaning roller 7 so that the left and right ends form a whole with the connection points of the screw rod 3 and the guide rod 4 respectively, and then when the screw rod 3 rotates, the guide rod 4 can limit the adjustment plate 6 on the same side, ensuring that the adjustment plate 6 can use the thread pushing force to move up and down stably, thereby driving the soft cleaning roller 7 to automatically clean the solar photovoltaic panel 8.

[0025] Furthermore, structures such as the soft cleaning roller 7, the adjustment plate 6, the screw rod 3 and the guide rod 4 are symmetrically arranged in two identical groups along the installation frame 1, which can simultaneously clean both sides of the solar photovoltaic panel 8 and improve the cleaning efficiency.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, a slot 9 is provided on the opposite side of the surface of the vertical rod body of the mounting frame 1, and a recessed groove 10 is provided above the inner surface of the slot 9, a thrust spring 11 is fixedly installed on one side of the inner surface of the recessed groove 10, and a stopper 12 is fixedly installed on the end of the thrust spring 11 close to the slot 9, and one end of the stopper 12 is located inside the slot 9, and an inclined surface is set above the surface, and the end of the stopper 12 away from the slot 9 is located on the inner side of the thrust spring 11. A pull rod 13 is fixedly installed, and one end of the pull rod 13 slides through the mounting frame 1, and an insert block 14 is provided at the lower part of the slot 9, and a universal ball 15 is rotatably provided on the surface of the insert block 14 close to the inner surface of the slot 9, and the opposite side of the insert block 14 is fixedly connected to the left and right ends of the solar photovoltaic panel 8, and support frames 16 are rotatably provided on the left and right sides of the surface of the mounting frame 1 through bearings, and a locking motor 17 is fixedly installed on the right side of the surface of the right support frame 16, and the rotating shaft end of the locking motor 17 passes through the support frame 16 and is connected to the mounting frame 1.

[0027] Furthermore, the upper surface of the block 12 is set as an inclined surface, so that the insert block 14 can push the block 12 to converge into the groove 10 through the inclined surface, and then stably insert it into the slot 9, while the lower surface of the block 12 is a plane, and thus cannot be pushed and contracted from the bottom up. After the insert block 14 is fully inserted, the stable installation of the solar photovoltaic panel 8 can be ensured.

[0028] Furthermore, the universal ball 15 rolls on the surface of the insert block 14 , preferably in contact with the inner surface of the slot 9 , thereby reducing the friction between the slot 9 and the insert block 14 .

[0029] Furthermore, the pull rod 13 passes through the mounting frame 1 and is connected to the block 12 , and the block 12 can be retracted into the sink 10 by pulling the pull rod 13 , thereby opening the upper end of the slot 9 and disassembling the solar photovoltaic panel 8 .

[0030] Furthermore, the locking motor 17 can directly drive the mounting frame 1 to rotate, thereby driving the solar photovoltaic panel 8 to adjust the light irradiation angle, so that the solar photovoltaic panel 8 can fully absorb light energy.

[0031] Working principle: When using the solar panel self-cleaning bracket, first, insert the solar photovoltaic panel 8 into the slot 9 through the plug blocks 14 on both sides. The plug block 14 uses the upper side slope of the block 12 to push the block 12 into the sink 10. When the plug block 14 is fully inserted into the bottom end of the slot 9, the thrust spring 11 can push the block 12 to extend and re-block the upper socket of the slot 9, and the bottom end of the block 12 is a horizontal plane, so it cannot be pushed and contracted, so that the solar photovoltaic panel 8 and the mounting frame 1 are stably assembled, and then the whole device is fixed by the support frame 16, and the mounting frame 1 is driven to rotate by the locking motor 17 to change the angle of the receiving surface of the solar photovoltaic panel 8, so as to fully absorb light energy and be placed for long-term use. The solar photovoltaic panel 8 has dust on its surface, and the rear screw 3 is driven to rotate by the driving motor 5. The front screw 3 rotates synchronously under the transmission of the pulley 501 using the synchronous belt. The horizontal whole composed of the same-side adjustment plate 6 and the soft cleaning roller 7 is limited by the left guide rod 4, so that the adjustment plate 6 will drive the soft cleaning roller 7 to move up and down along the front and back sides of the surface of the solar photovoltaic panel 8, and automatically clean the solar photovoltaic panel 8. When the solar photovoltaic panel 8 needs maintenance and replacement, the stopper 12 can be retracted into the sink 10 by pulling the pull rod 13, and the plug block 14 can slide out of the slot 9 to disassemble, maintain and replace the solar photovoltaic panel 8. This is the working principle of the solar panel self-cleaning bracket.
