Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic panel cleaning, and in particular relates to a multifunctional cleaning robot for photovoltaic panels. Background Art

[0002] Photovoltaic panels, also known as solar photovoltaic panels, are power generation devices that generate direct current (DC) electricity when exposed to sunlight. They consist of multiple solar cells that convert sunlight into electricity. When sunlight strikes a panel, the semiconductor material in the cells absorbs the light energy, stimulating electrons to generate an electric current. This electricity is then transmitted via wires to the power grid or stored in batteries for future use.

[0003] With the vigorous promotion of new energy technologies, the application of photovoltaic panels is increasing. Photovoltaic panels absorb sunlight to store energy. Excessive dust and dirt on the surface of photovoltaic panels can seriously affect their energy storage efficiency. Therefore, regular cleaning of the surface of photovoltaic panels is necessary.

[0004] In existing technology, the surfaces of photovoltaic panels are mostly cleaned manually by flushing. However, simple flushing can only remove surface dust, while high-pressure flushing poses the risk of damaging photovoltaic devices. Currently, those skilled in the art have proposed using cleaning robots to clean the surfaces of photovoltaic panels. However, most existing robots lack a secondary cleaning function. Typically, the robot performs a primary cleaning operation on the panel surface using a cleaning brush while the robot is moving. If any residual dirt remains on the panel surface, manual cleaning or restarting the robot for another cleaning operation is required, resulting in low cleaning efficiency. Summary of the Invention

[0026] Example 1

[0027] like Figure 1 As shown, a multifunctional cleaning robot for photovoltaic panels includes a driving trolley, a primary cleaning mechanism and a secondary cleaning mechanism 7. The primary cleaning mechanism and the secondary cleaning mechanism 7 are respectively installed at the front end and the rear end of the driving trolley. A ranging and positioning device is installed on the top of the driving trolley. The ranging and positioning device plans the movement trajectory of the driving trolley through the laser radar ranging principle, and targets special stains such as bird droppings on the photovoltaic panels. In the process of driving the trolley, the primary cleaning mechanism cleans the dust on the surface of the photovoltaic panel, and the secondary cleaning mechanism 7 performs a secondary cleaning on the surface of the photovoltaic panel by locating special stains through the ranging and positioning device.

[0028] like Figure 1 As shown, the primary cleaning mechanism includes a connecting rod 3, an adjustment box 4, a cleaning roller 5 and a self-cleaning roller 6, wherein a plurality of cleaning rollers 5 are provided, and a self-cleaning roller 6 is arranged at the top center between adjacent cleaning rollers 5. The cleaning roller 5 is used to clean the surface of the photovoltaic panel, and the self-cleaning roller 6 is used to clean the surface of the cleaning roller 5 to keep the surface of the cleaning roller 5 clean and tidy, thereby improving the cleaning effect of the cleaning roller 5 on the photovoltaic panel.

[0029] The ends of the cleaning roller 5 and the self-cleaning roller 6 are respectively connected to the regulating box 4, and the other end of the regulating box 4 is connected to the connecting rod 3. The connecting rod 3 is installed on the main vehicle body 1. The regulating box 4 and the connecting rod 3 can move relative to each other, so that the cleaning roller 5 and the self-cleaning roller 6 can move up and down with the regulating box 4. When the cleaning roller 5 moves downward to contact the photovoltaic panel, the photovoltaic panel is cleaned. The interior of the regulating box 4 is equipped with a drive assembly for driving the cleaning roller 5 and the self-cleaning roller 6 to rotate. Any drive assembly structure that can achieve synchronous rotation of the cleaning roller 5 and the self-cleaning roller 6 in the prior art is applicable and will not be described in detail here.

[0030] like Figure 2 As shown, in this embodiment, two cleaning rollers 5 are provided and one self-cleaning roller 6 is provided. The self-cleaning roller 6 is located above the cleaning roller 5. The line connecting the centers of the two cleaning rollers 5 and the center of one self-cleaning roller 6 is a triangle. A cover plate 8 is mounted on the top of the cleaning roller 5 and the self-cleaning roller 6. The cross-section of the cover plate 8 is arc-shaped. Drainage parts 9 are respectively provided on both sides of the cover plate 8. The tip of the drainage part 9 contacts the surface of the cleaning roller 5. In order to avoid damaging the cleaning roller 5, the drainage part 9 is made of soft and elastic materials such as rubber.

[0031] Specifically, the cleaning roller 5 and the self-cleaning roller 6 are both cylindrical. Specifically, the self-cleaning roller 6 includes a brush portion 601 and a water reservoir 602. The brush portion 601 has a cleaning brush on its surface for cleaning dust and hair from the surface of the cleaning roller 5. The water reservoir 602 is hollow and stores clean water. The surface of the water reservoir 602 has a plurality of through holes arranged in an array.

[0032] When the cleaning roller 5 and the self-cleaning roller 6 rotate, the cleaning roller 5 contacts the photovoltaic panel to clean the photovoltaic panel, and the brush portion 601 of the self-cleaning roller 6 contacts the surface of the cleaning roller 5 to clean the cleaning roller 5 .

[0033] The clean water inside the water storage part 602 of the self-cleaning roller 6 is thrown out under the action of the centrifugal force generated by the rotation, splashes to the inner wall of the cover plate 8, and flows to the surface of the cleaning roller 5 by relying on the arc structure of the cover plate 8 and the drainage effect of the drainage part 9. Due to the rotation of the cleaning roller 5, the clean water passing through the drainage part 9 can drip evenly to the surface of the cleaning roller 5.

[0034] In addition, when the water storage part 602 rotates to the bottom of the brush part 601, the clean water inside the water storage part 602 can drip onto the photovoltaic panel through the gap between two adjacent cleaning rollers 5, and the surface of the photovoltaic panel can be regularly sprinkled with water to improve the cleaning effect.

[0035] Example 2

[0036] like Figure 3As shown, the structure of this embodiment is basically the same as that of the first embodiment, except that the secondary cleaning mechanism 7 in this embodiment includes an installation box 701, a screw 702, a driving member 1 703, a slider 704, a connecting plate 705, a lifting member 706, a driving member 2 707, a lifting plate 708, a cleaning turntable 709, a rotating rod 7010, and a transmission member 7011.

[0037] The installation box 701 is installed on the outer wall of the main vehicle body 1, and the screw 702 is arranged inside the installation box 701. The screw 702 is driven to rotate by the driving member 1 703. The two ends of the screw 702 are connected to the installation box 701. The slider 704 is sleeved with the screw 702. The slider 704 is connected with a connecting plate 705. The connecting plate 705 is installed with a lifting plate 708 through a lifting member 706. The interior of the lifting plate 708 is hollow and is installed with a rotating rod 7010. One end of the rotating rod 7010 extends out of the lifting plate 708 and is installed with a cleaning turntable 709. A cleaning cloth is sleeved on the cleaning turntable 709. The rotating rod 7010 is driven to rotate by the transmission member 7011 and the driving member 2 707.

[0038] In one embodiment, the lifting member 706 can be a telescopic rod. In another embodiment, the connecting plate 705, the lifting member 706, and the lifting plate 708 form a lifting platform structure. The primary purpose of both embodiments is to drive the cleaning turntable 709 up and down. Furthermore, the transmission member 7011 includes a transmission chain and a transmission gear. Through the cooperation between the transmission chain and the transmission gear, the second driving member 707 can drive the rotating rod 7010 to rotate.

[0039] When the ranging and positioning device detects special stains that require secondary cleaning, the screw 702 is driven to rotate by the driving member 703, which drives the slider 704 to move and adjust the horizontal position of the cleaning turntable 709. The lifting member 706 then drives the lifting plate 708 to move and adjust the vertical position of the cleaning turntable 709, so that the cleaning turntable 709 accurately falls into the position on the photovoltaic panel that requires secondary cleaning. The driving member 707 and the transmission member 7011 cooperate to drive the rotating rod 7010 to rotate, so that the cleaning turntable 709 can drive the cleaning cloth to wipe the surface of the photovoltaic panel.

[0040] Example 3

[0042] Among them, the transverse mechanism 12 is installed inside the main vehicle body 1, the slide 13 is slidably connected to the transverse mechanism 12, and a receiving plate 15 is connected to the slide 13. One end of the receiving plate 15 is connected to the cleaning box 16, and the other end of the receiving plate 15 is connected to the counterweight block 14. The receiving plate 15 moves back and forth on the transverse mechanism 12 with the slide 13, driving the cleaning box 16 to extend out of the main vehicle body 1 and move to the bottom of the installation box 701.

[0043] like Figure 5 As shown, when the cleaning box 16 is located inside the main vehicle body 1, one end of the receiving plate 15 is mounted on the side wall of the main vehicle body 1 to improve the stability of the cleaning box 16. Figure 4 As shown, when the cleaning box 16 moves to the bottom of the installation box 701 , the balance weight 14 ensures the stability of the cleaning box 16 .

[0044] Specifically, such as Figure 3 As shown, a partition 17 and a nozzle 18 are installed inside the cleaning box 16. There are multiple nozzles 18, some of which are located on the side walls of the cleaning box 16, and others are located at the bottom of the cleaning box 16. They are used to spray clean water on the cleaning cloth on the cleaning turntable 709 in an all-round manner. The partition 17 is a grid structure and is located above the nozzle 18 at the bottom of the cleaning box 16. On the one hand, the partition 17 is used to receive the rinsing action of the cleaning turntable 709 in the secondary cleaning mechanism 7, and on the other hand, it is used to protect the nozzle 18 inside the cleaning box 16.

[0045] After the secondary cleaning mechanism 7 completes the secondary cleaning operation of the photovoltaic panel, the position of the cleaning turntable 709 is adjusted to the rinsing position, and the cleaning box 16 is moved to the bottom of the secondary cleaning mechanism 7. After the cleaning turntable 709 is moved downward into the cleaning box 16, the cleaning cloth is sprayed through the nozzle 18. At the same time, the cleaning turntable 709 rotates and moves up and down, and the rinsing operation is achieved by squeezing with the partition 17 to complete the cleaning of the cleaning cloth.

[0046] like Figure 1 As shown, the driving trolley includes a main body 1 and suction cup tracks 2. The suction cup tracks 2 are installed on both sides of the main body 1. The suction cup tracks 2 enable the main body 1 to move on the smooth and inclined photovoltaic panels. Specifically, the main body 1 includes an upper box body and a lower box body. The driving structure of the suction cup tracks 2 is installed in the lower box body, which will not be described in detail here. A waste water tank 10 and a clean water tank 11 are installed in the upper box body; in addition, a cleaning liquid tank can also be installed in the upper box body of the main body 1. The waste water tank 10 is connected to the cleaning tank 16 to receive the waste water inside the cleaning tank 16; the clean water tank 11 is connected to the self-cleaning roller 6 to transport clean water to the water storage part 602 of the self-cleaning roller 6; the cleaning liquid tank is connected to the nozzle 18 to spray cleaning liquid onto the cleaning cloth on the cleaning turntable 709 to facilitate the removal of special stains.
