Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the protection scope of the present application.

[0032] Embodiment 1

[0033] Please refer to Figures 1-6 .

[0034] The present application provides a photovoltaic panel 1 dust removal device, mainly solves the problem in the prior art that the dust on the photovoltaic panel 1 is removed by static electricity, which is inconvenient to clean, has high energy consumption and low integration of equipment, and often causes some uncleaned parts to be cleaned during cleaning, which requires repeated operation of the cleaning equipment to clean the dust in a certain area of the photovoltaic panel 1; in order to solve the above problem, the technical scheme sets the static generator, a plurality of static conductive members and a plurality of groups of rolling brush assemblies in the rack 2, the rack 2 is welded from a plate material, and the inside is provided with a horizontal rod and other components for mounting the static generator; walking mechanisms 3 are arranged at both ends of the rack 2; the walking parts of the walking mechanisms 3 are arranged on the outer frame of the photovoltaic panel 1 or the outer wall of the photovoltaic panel 1 and drive the rack 2 to move along the installation direction of the photovoltaic panel 1;

[0035] The static electricity generator is installed in the rack 2; a plurality of groups of rolling brush assemblies are arranged in the rack 2; a plurality of static electricity conductors are correspondingly arranged in the rolling brush assemblies and connected with the static electricity generator; in this way, when the device works, the dust adhered to the photovoltaic panel 1 is first brushed by the rolling brush assembly; when the dust is broken and loosened by the rolling brush assembly, the static electricity generator randomly applies static electricity to the static electricity conductors, and the static electricity also acts on the bristle part of the rolling brush assembly, so that the dust is gradually adhered to the bristles of the bristle part; because the bristles in the rolling brush assembly are always in a rotating state, the dust will be as much as possible to be adsorbed by the bristle part, avoiding the problem that the single grid or electrode cannot be adhered again after covering the surface of the dust cover, and improving the dust removal efficiency; the number of the rolling brush assemblies is at least 8, so that at least 8 groups of rolling brush assemblies can seamlessly connect to clean the same surface of the photovoltaic panel 1 when the transmission assembly rotates in the rack 2; and the rotation direction of the transmission assembly is perpendicular to the installation direction of the photovoltaic panel 1, which can increase the friction between the rolling brush assembly and the photovoltaic surface, so as to remove more stubborn dust stains and improve the cleaning effect.

[0036] Further, the specific structure of the walking structure includes a fixed frame, the fixed frame is fixed on both sides of the rack 2 through bolts; two walking wheels are rotatably arranged in the fixed frame, the walking wheels are provided with a track in a sleeved manner, the track is made of rubber material, the walking ability of the device on the photovoltaic panel 1 can be improved, and the surface of the photovoltaic panel 1 will not be damaged, and a servo motor is installed on the fixed frame, the servo motor is connected with one of the walking wheels through a coupling, so that the device can provide strong power for movement on the photovoltaic panel 1.

[0037] Further, the static electricity generator is composed of a static electricity emitter (rod) and a direct-current high-voltage power supply. The direct-current high-voltage power supply provides negative (or positive) high voltage to the static electricity emitter (rod), so that the static electricity emitter (rod) emits negative (or positive) electricity and then charges the object (workpiece) (artificial charging). The higher the voltage, the larger the effective range.

[0038] In some technical solutions of the present application, the rolling brush assembly comprises an installation frame 8, a plurality of cleaning rollers 14 are rotatably arranged in the installation frame 8, and a bristle sleeve 18 is sleeved on the side wall of the cleaning roller 14. The installation frame 8 is square, hollow, and made of steel. The number of cleaning rollers 14 is at least 3, and the three cleaning rollers 14 are rotatably arranged on the inner wall of the installation frame 8 through rotating shafts. In this way, the cleaning rollers 14 in the installation frame 8 can rotate by themselves under the friction force when they contact the photovoltaic panel surface, ensuring the dust treatment capacity of the rolling brush assembly, without the need for additional driving force, simplifying the structure and saving energy. When the bristle sleeve 18 contacts the outer glass of the photovoltaic panel 1, it will not scratch the glass, and it has good static electricity conduction ability.

[0039] In some technical schemes of the present application, a partition plate 20 is installed between any two adjacent cleaning rollers 14, and the partition plate 20 is connected with the inner wall of the mounting frame 8. The partition plate 20 is arranged between any two adjacent cleaning rollers 14 in the same mounting frame 8, which can avoid the bristles of the bristle sleeve 18 on the cleaning roller 14 from being entangled with each other, so that the bristle sleeve 18 that has been covered with dust will shake off the dust, affecting the dust processing capacity of the device. When the roller brush assembly does not enter the dust collecting sleeve 9, the electrostatic conductor is always in an energized state.

[0040] In some technical schemes of the present application, the transmission assembly includes a mounting frame 10, a transmission belt 7 and at least two groups of transmission rollers 6. The mounting frame 10 is arranged in the rack 2, and the two groups of transmission rollers 6 are rotatably arranged at the two ends of the mounting frame 10. The transmission belt 7 is connected at the head and tail and is in transmission connection with the two groups of transmission rollers 6. A plurality of roller brush assemblies are equidistantly arranged on the outer side wall of the transmission belt 7 along the transmission direction of the transmission belt 7. The transmission belt 7 is a flexible rubber transmission belt 7. The mounting frame 8 is fixed on the outer circumferential wall of the transmission belt 7 by bolts. The mounting frame 10 is fixed on the inner wall of the rack 2 by bolts. The transmission roller 6 is rotatably arranged in the mounting frame 10 through a shaft and a shaft sleeve. The transmission belt 7 and the transmission roller 6 are in transmission connection through friction. When at least 8 groups of roller brush assemblies make circumferential movement in the rack 2, the surface of the photovoltaic panel 1 can be seamlessly cleaned, and the cleaning effect of the same area of the photovoltaic panel 1 can be improved.

[0041] Further, the rotation direction of the cleaning roller 14 is the same as the transmission direction of the transmission belt 7.

[0042] Further, the transmission roller 6 is internally provided with a motor, which can ensure normal operation of the transmission roller 6 in the rack 2.

[0043] Further, the transmission speed of the transmission belt 7 is different from that of the cleaning roller. The rotation speed of the cleaning roller 14 is higher than that of the transmission belt 7. In this way, the friction between the roller brush assembly and the photovoltaic panel surface can be increased, so that more stubborn dust stains can be removed, and the cleaning effect can be improved.

[0044] In some technical schemes of the present application, the electrostatic conductor includes a plurality of electrostatic conductive rods 19 corresponding to the cleaning roller 14. The cleaning roller 14 is hollow, the electrostatic conductive rod 19 is arranged in the cleaning roller 14, and the electrostatic conductive rod 19 is connected with the electrostatic generator. The electrostatic conductive rod 19 is arranged in the mounting frame 8 and placed in the interior of the cleaning roller 14. The axis of the electrostatic conductive rod 19 is coaxial with the axis of the cleaning roller 14. The electrostatic conductive rod 19 is fixed on the outer side wall of the mounting frame 8 through a fixing plate. The electrostatic conductive rod 19 is electrically connected with the electrostatic generator through a power receiving assembly.

[0045] The power receiving assembly comprises a conductive ring body 22 arranged at the bottom of the inner wall of one side of the rack 2, the static conductive rods 19 in the same static conductive element are connected in parallel, and then abut against the conductive ring body 22 arranged at the bottom of the inner wall of one side of the rack 2 through the fixing member, and the conductive ring body 22 and the fixing member 21 (copper sheet) can slide relative to each other, the fixing member 21 has a certain elasticity, and is similar to a spring sheet structure. The output end of the static generator 23 is also electrically connected to the conductive ring body 22 through a cable. The conductive ring body 22 comprises a vertical section and two circular arc sections, the two circular arc sections are integrally formed with the vertical section, and a part of one of the circular arc sections is arranged in the integrated sleeve 9, and the other arc section is a quarter of a circle in length. The vertical section is located at the lower side of the inner wall of the rack 2, and is used for ensuring that the static conductive rods 19 in the static conductive element at the working surface receive stable output voltage. When the transmission belt drives the roller brush assembly to move counterclockwise, one of the plurality of roller brush assemblies arranged at the bottom of the rack moves to the top of the rack under the driving of the transmission belt, the fixing member 21 on the roller brush assembly is separated from the conductive ring body 22, at this time, the static conductive rod 19 is not electrically connected to the static generator 23, so that the dust attached in the roller brush assembly can be cleaned in the later period. Conversely, when one of the plurality of roller brush assemblies in the rack top moves to the two sides of the rack under the driving of the transmission belt, the fixing member 21 on the roller brush assembly is in contact with the conductive ring body 22, so as to provide a continuous and stable voltage for the static conductive rod 19. Through the above structure, the transmission belt can also move in the rack 1 in the opposite direction of the initial movement direction, at this time, the static conductive rod 19 is also electrified, can repeatedly rub the more stubborn stains, and improves the stain treatment effect.

[0046] In some technical solutions of the application, a pressing assembly for pressing the brush sleeve 18 in the roller brush assembly against the photovoltaic panel 1 is arranged between the transmission belt 7 and the roller brush assembly.

[0047] In some technical solutions of the present application, the lower pressing assembly comprises a frame body mounted on the outer side wall of the conveying belt 7, a fixed clamping seat 15 is arranged in the frame body, a mounting plate 17 is mounted on the telescopic end of the fixed clamping seat 15, and a plurality of limiting springs 16 are arranged between the mounting frame 8 and the mounting plate 17. The lower pressing assembly is arranged to facilitate the closer contact between the roller brush assembly and the photovoltaic panel 1, i.e. the fixed clamping seat 15 pushes the mounting frame 8 to move in the direction of the photovoltaic panel 1; a downward pressure is applied to the roller brush assembly, so that the brush sleeve 18 is in better contact with the photovoltaic panel 1, thereby improving the dust cleaning capacity of the device; in addition, the mounting plate 17 mounted on the telescopic end of the fixed clamping seat 15 is ball-hinged with the mounting frame 8, so that the movement range of the mounting frame 10 is increased, and the hard contact between the brush sleeve 18 in the mounting frame 8 and the panel surface of the photovoltaic panel 1 is avoided; the photovoltaic panel 1 is protected; and at least four limiting springs 16 are arranged between the mounting frame 8 and the mounting plate 17, so that the mounting frame 8 can float in space and adaptively contact the panel surface of the photovoltaic panel 1, thereby applying a downward pressure to the dust accumulated on the photovoltaic panel 1, increasing the ability of the device to break up dust blocks, and achieving dust removal efficiency on the panel surface of the photovoltaic panel 1 under different working conditions.

[0048] Further, due to the action of the limiting spring 16 in the lower pressing assembly, the fixed part 21 on the mounting frame can be in better contact with the conductive ring body 22 under the downward pressure of the lower pressing assembly, so as to ensure the stable voltage output of the electrostatic conductor; and the fixed part and the conductive ring body can achieve adaptive contact.

[0049] In some technical solutions of the present application, the rack 2 is provided with a cleaning assembly for collecting dust in any one of the roller brush assemblies.

[0050] In some technical solutions of the present application, the cleaning assembly comprises a negative pressure device 5, a dust collecting bin 4 and a dust collecting sleeve 9 which are mounted in the rack 2 and sequentially communicate; and the conveying belt 7 extends outward after penetrating through the dust collecting sleeve 9.

[0051] The negative pressure device 5 is arranged on the top of the rack 2, the dust collecting bin 4 communicates with the negative pressure device 5, the dust collecting bin 4 is also fixed on the top of the rack 2, the dust collecting sleeve 9 is arranged on the conveying belt 7, the dust collecting bin 4 is provided with an inverted funnel 11, the large-diameter end of the funnel 11 communicates with the dust collecting sleeve 9 through a pipeline; the small-diameter end of the funnel 11 is provided with a one-way valve 12; the one-way valve is an electronic one-way valve which can be opened when the device cleans dust in the roller brush assembly; and when one of the roller brush assemblies is arranged in the dust collecting sleeve 9, the electrostatic conductor in the roller brush assembly will not be electrically connected with the electrostatic generator, at this time, the cleaning roller 14 will continuously rotate to throw the dust on the brush sleeve 18 as far as possible, so that the suction force generated by the negative pressure device 5 can suck the dust into the dust collecting bin 4, so as to ensure that the roller brush assembly is in a relatively clean state, thereby facilitating the next operation, i.e. cleaning the next panel surface of the photovoltaic panel 1.

[0052] Further, a plurality of cleaning parts 24 are arranged on the inner top wall of the dust collecting sleeve 9, and the cleaning part 24 is a protruding or obliquely arranged scraper, which can actively clean the dust on the brush sleeve 18 of the cleaning roller 14.

[0053] Further, the two ends of the mounting frame are open, and the transmission belt is also hollow, so that the dust can enter the dust collecting sleeve 9, and the negative pressure equipment can process and adsorb the dust discharged from the brush sleeve 18, thereby improving the dust processing effect of the equipment.

[0054] Further, a gas curtain composed of brushes is arranged at the output end of the dust collecting sleeve 9, which can discharge the dust from the dust collecting sleeve 9, and can also clean the dust attached to the transmission belt, thereby avoiding the pollution of the cleaned photovoltaic panel surface.

[0055] In some technical solutions of the present application, the outer periphery of the rack 2 is provided with a negative pressure channel 13 connected at both ends, the negative pressure channel 13 is provided with an inlet and an outlet on the side wall opposite to the photovoltaic panel 1, and the negative pressure channel 13 is in communication with the negative pressure equipment 5. The negative pressure channel 13 connected at both ends and in a ring shape is fixed on the outer peripheral wall of the rack 2 by buckling, and the negative pressure channel 13 can first adsorb and remove the dust on the photovoltaic panel 1 by the rolling brush assembly, and when the stubborn dust attached to the photovoltaic panel 1 cannot be adsorbed by the negative pressure channel 13, the dust is cleaned again by the rolling brush assembly cooperating with the static electricity conducting piece, and a plurality of rolling brush assemblies can also clean the same area of the photovoltaic panel 1 for multiple times, thereby improving the cleaning effect of the photovoltaic panel 1. Such arrangement can also avoid the dust cleaned by the rolling brush assembly from splashing out of the cleaning area, thereby avoiding the pollution of the cleaned photovoltaic panel 1 surface area.

[0056] The above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes.
