Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel cleaning equipment technology, specifically a structure for cleaning sand and dust from photovoltaic panels used in new energy photovoltaic and wind power. Background Technology

[0002] Photovoltaic power generation, as an important component of new energy, has been widely used in deserts, Gobi and other areas with abundant sunshine but frequent sandstorms. However, the deposition of sand and dust on the surface of photovoltaic panels is one of the core issues affecting power generation efficiency. Sand and dust blockage will lead to a decrease in light transmittance, which can cause power generation loss in severe cases. Therefore, regular cleaning of sand and dust on the photovoltaic panel surface is a necessary part of the operation and maintenance of photovoltaic power plants.

[0003] Currently, dust removal from photovoltaic panels mainly relies on brush roller contact cleaning equipment, which involves rotating brushes or rollers to directly contact the surface of the photovoltaic panel, brushing the dust off the panel, and then using negative pressure suction or natural airflow to carry away the dust. However, the existing cleaning equipment mentioned above poses a risk of scratching. The surface of the photovoltaic panel is made of glass, and the dust particles contain hard minerals such as quartz. When the brush roller pushes the dust to slide on the panel surface, it is equivalent to the abrasive grinding the glass surface. After long-term use, micro-scratches will appear on the panel surface, and the light transmittance will continue to decrease. In addition, the problem of secondary dust generation during the cleaning process is serious. Only a portion of the dust stirred up by the brush rollers is collected by the dust suction port. A considerable proportion of the dust diffuses and escapes, then re-settles in the cleaned area or adjacent panels, causing secondary pollution. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a dust cleaning structure for photovoltaic panels used in new energy photovoltaic and wind power, which has the advantages of not damaging the photovoltaic panel surface, eliminating secondary dust generation, providing good cleaning effect, and being suitable for the operation and maintenance of new energy photovoltaic equipment.

[0005] (II) Technical Solution The above-mentioned technical objective of the present invention is achieved through the following technical solution: a dust cleaning structure for photovoltaic panels used in new energy photovoltaic and wind power, including a walking track fixedly installed on the frame of the photovoltaic panel and a walking frame installed on the walking track. Dust collection boxes and compressed air sources are respectively installed at both ends of the top of the walking frame, and a dust cleaning mechanism is installed inside the walking frame. The dust removal mechanism includes a negative pressure suction pipe and two blowing pipes installed inside the walking frame. The two blowing pipes are symmetrically distributed on both sides of the negative pressure suction pipe. A dust collection channel is provided at the top of the blowing pipe. Two arc-shaped guide plates are fixedly connected to both ends of the dust collection channel, forming a guide channel between adjacent guide plates. The negative pressure suction pipe has multiple series-connected contraction sections along its length. Several suction pipes are spaced apart at the top of the dust collection channel along its length. The other end of each suction pipe is connected to a contraction section. A mounting plate is fixedly connected above the dust collection channel. Multiple spaced vibration stripping components are bolted to the front side of the mounting plate along its length.

[0006] By adopting the above technical solution, a dust removal mechanism is set up. Compressed air is supplied to two purging pipes. The airflow in the purging pipes blows the dust away from the panel surface and is guided by the arc-shaped guide plates at both ends of the dust collection channel. The airflow containing dust passes through the guide channel between the two guide plates and enters the dust collection channel, where it is sucked away by the negative pressure suction pipe. At the same time, the vibration peeling component applies high-frequency micro-amplitude vibration to the panel surface to help loosen and fall off the dust. Through this cleaning method of vibration pre-peeling, airflow guidance, and distributed negative pressure suction, non-contact dust removal of photovoltaic panel surface is achieved without secondary dust generation. It has the advantages of not damaging the photovoltaic panel surface, no secondary dust generation, good cleaning effect, and suitability for operation and maintenance of new energy photovoltaic equipment.

[0007] The invention is further configured such that: the vibration stripping assembly includes a mounting frame, a flexible pad is provided at the bottom of the mounting frame, a plurality of vibration springs are provided between the flexible pad and the mounting frame, a housing is bolted to the top of the mounting frame, an end cap is bolted to the left side of the housing, a rolling groove is provided inside the housing, a central column is provided inside the rolling groove, a track ring is fixedly fitted on the surface of the central column, a ball is provided inside the track ring, and the surface of the ball contacts the rolling groove and the track ring respectively, and an air inlet groove and an air outlet groove are provided at the top of both ends of the housing respectively, and the air inlet groove and the air outlet groove are both connected to the rolling groove.

[0008] By adopting the above technical solution, a vibration stripping component is set up. Compressed air enters the rolling groove inside the housing through the air inlet groove, driving the balls in the track ring to circulate at high speed along the rolling groove. The balls generate high-frequency vibration during the rolling process, which is transmitted through the housing to the mounting bracket and flexible pad, and finally to the surface of the photovoltaic panel. The vibration spring buffers and adjusts the vibration amplitude, so that the vibration energy transmitted to the panel surface is moderate. This can effectively strip away sand and dust without causing impact damage to the photovoltaic panel, thus achieving the effect of loosening and removing sand and dust.

[0009] The present invention is further configured such that: an air inlet pipe and a silencer are respectively provided at the top of both ends of the housing; the air inlet pipe and the silencer are respectively connected to the air inlet slot and the air outlet slot; a branch pipe is fixedly connected to the left end of the purging pipeline; and the end of the air inlet pipe near the branch pipe is fixedly connected to the branch pipe.

[0010] Using the above technical solution, the purging pipeline supplies air to the vibration stripping component through branch pipes and air inlet pipes, so that the vibration stripping and purging dust collection share the same compressed air source, eliminating the need for an independent power source. The silencer effectively reduces the noise of the vibration stripping component during operation and improves the working environment.

[0011] The present invention is further configured such that: a connecting frame is provided on the top of the mounting frame, the mounting frame is bolted to the mounting plate through the connecting frame, and a plurality of damping vibration isolators are provided between the mounting frame and the connecting frame at intervals along the length direction.

[0012] By adopting the above technical solution, the vibration of the vibration stripping component is isolated from the walking frame by the damping vibration isolator, so as to avoid the vibration from interfering with the stable operation of the walking mechanism, while reducing the fatigue damage of vibration to the frame and other components, and extending the service life of the equipment.

[0013] The present invention is further configured such that: a plurality of bidirectional lead screws are provided inside the walking frame, adjacent bidirectional lead screws are bolted together, and two first internal thread blocks are threaded onto the surface of the bidirectional lead screws. A connecting rod is rotatably connected to the bottom end of the first internal thread block, and the other end of the connecting rod is rotatably connected to the mounting plate.

[0014] Using the above technical solution, the drive motor pre-installed inside the walking frame drives the bidirectional lead screw to rotate, causing the two first internal thread blocks on the bidirectional lead screw to move towards or away from each other. The first internal thread blocks drive the mounting plate to rise and fall through the connecting rod, thereby adjusting the distance between the dust cleaning mechanism and the photovoltaic panel surface to adapt to the cleaning needs of photovoltaic panels of different thicknesses or different installation heights. Furthermore, adjacent bidirectional lead screws are bolted together to achieve synchronous rotation, ensuring that the two ends of the mounting plate rise and fall synchronously.

[0015] The invention is further configured such that: the dust removal mechanism also includes a dust separation component disposed within a dust collection box; the dust separation component includes a collection cylinder; a spiral dust discharger is disposed on the left side of the collection cylinder, and the other end of the spiral dust discharger extends to the outside of the dust collection box; a conical separation cylinder is fixedly connected to the top of the collection cylinder; a connecting pipe is fixedly connected to the left end of the negative pressure suction pipe; the other end of the connecting pipe is connected to the tangential inlet pipe of the conical separation cylinder; a central pipe is disposed at the top of the interior of the conical separation cylinder; the top of the central pipe extends to the outside of the conical separation cylinder and is connected to a clean air outlet pipe; the other end of the clean air outlet pipe is connected to the air inlet of a compressed air source; and a secondary separation unit is disposed inside the central pipe.

[0016] By adopting the above technical solution, and by setting up a dust separation component, the dust-laden airflow enters the connecting pipe through the negative pressure suction pipe, and then enters the conical separation cylinder through the tangential inlet pipe. The dust-laden airflow rotates at high speed inside the conical separation cylinder, and larger dust particles are thrown against the cylinder wall under the action of centrifugal force, spiraling down along the wall and entering the collection cylinder. It is then discharged from the dust collection box by the spiral dust discharger. The clean airflow after primary separation rises into the central pipe, and after further purification by the secondary separation unit, it flows back from the clean air outlet pipe to the air inlet pipe of the compressed air source. This achieves the separation and collection of dust, avoiding environmental pollution and photovoltaic panel surface pollution. Furthermore, the clean air flowing back to the compressed air source reduces the consumption of compressed air and improves energy utilization efficiency.

[0017] The invention is further configured such that: the secondary separation unit includes a perforated plate rotatably connected inside the central tube; an annular filter screen is fixedly disposed at the bottom of the perforated plate; an annular dust guide plate is disposed on the inner side of the annular filter screen; the bottom end of the annular dust guide plate is flush with the central tube, and an annular dust guide gap is formed between the annular dust guide plate and the inner wall of the central tube; a rotating shaft is bolted to the bottom of the perforated plate; a rotating blade is bolted to the bottom end of the rotating shaft; a bracket is bolted to the inner side of the annular dust guide plate; the bracket is rotatably mounted on the surface of the rotating shaft; a plurality of striking rods are distributed circumferentially at the top end inside the annular dust guide plate; the striking rods are slidably connected to the annular dust guide plate; a tension spring is sleeved on the surface of the striking rod; the two ends of the tension spring are respectively connected to the striking rod and the annular dust guide plate; the end of the striking rod near the annular filter screen contacts the annular filter screen; and a plurality of protrusions are disposed circumferentially at the bottom end of the inner side of the annular filter screen, and the protrusions cooperate with the striking rods.

[0018] By employing the above technical solution, a secondary separation unit is set up. The airflow after primary separation enters the central tube, driving the rotating blades to rotate. The rotating blades drive the perforated plate and annular filter screen to rotate via a rotating shaft, ensuring that the annular filter screen makes full and comprehensive contact with the airflow, allowing the annular filter screen to perform secondary filtration of residual fine dust in the airflow. Simultaneously with the rotation of the rotating shaft, the protrusion at the bottom inner side of the annular filter screen periodically pushes the striking rod to slide outward. The striking rod rebounds under the action of a tension spring, striking the annular filter screen and shaking off the dust adhering to the filter screen, which is then discharged through the annular guide gap between the annular dust guide plate and the central tube. This secondary separation component utilizes the kinetic energy of the airflow itself to drive the rotating blades to rotate, thereby rotating the annular filter screen for secondary filtration. No additional power source is required, and the cooperation between the striking rod and the protrusion enables online self-cleaning of the filter screen, avoiding filter screen clogging and ensuring the continuous effectiveness of secondary separation.

[0019] The invention is further configured such that: a drive wheel walking mechanism is bolted to the bottom of both ends of the walking frame, the drive wheel walking mechanism is located inside the walking track and works in conjunction with it, and a support wheel is bolted to the middle of the front and rear sides of the walking frame, the support wheel being located on the edge of two adjacent photovoltaic panels.

[0020] By adopting the above technical solution, the precise guidance of walking is ensured by the cooperation between the drive wheel walking mechanism and the walking track, while the design of the support wheel straddling the frame of the adjacent photovoltaic panel allows the walking frame to smoothly cross the gap between the panels, ensuring walking stability.

[0021] The present invention is further configured such that: both ends of the walking frame are rotatably connected to screws, the surface of the screws is threaded with a second internal thread block, both ends of the second internal thread block are fixedly connected to a sliding frame, the bottom end of the sliding frame is fixedly connected to a limit wheel, and the limit wheel is in rolling contact with the walking track.

[0022] Using the above technical solution, the operator rotates the screw, driving the second internal thread block to move along the screw axis. The second internal thread block drives the sliding frame and the limit wheel to move synchronously, adjusting the contact position and pressure between the limit wheel and the traveling track, ensuring the stable operation of the traveling frame on the track, and preventing travel deviation or shaking caused by poor contact.

[0023] The present invention is further configured such that: a guide post runs through the interior of the sliding frame, and both ends of the guide post are fixedly connected to the inner wall of the walking frame.

[0024] By adopting the above technical solution, the guide post through the sliding frame can provide linear guidance for the sliding frame, ensuring the linearity and stability of the movement of the limit wheel.

[0025] (III) Beneficial Effects Compared with the prior art, the present invention provides a structure for cleaning sand and dust from photovoltaic panels used in new energy photovoltaic and wind power, which has the following beneficial effects: This new energy photovoltaic and wind power photovoltaic panel dust cleaning structure adopts a completely non-contact cleaning method that combines vibration peeling and pneumatic conveying. The vibration peeling component uses high-frequency micro-vibration to pre-peel the dust on the panel surface, and the air curtain formed by the blowing pipe blows the dust away from the panel surface. Finally, the negative pressure suction pipe and dust collection channel suck the dust into the dust collection box and dust separation component, thereby avoiding the abrasion and scratch problem caused by the brush roller pushing the dust to slide on the panel surface, effectively protecting the light transmittance and power generation efficiency of the photovoltaic panel. By setting up a sand and dust separation component, dust-laden airflow can be separated and collected. After cleaning, the air flows back to the air inlet of the compressed air source, realizing the recycling of compressed air. The separated sand and dust are discharged from the dust collection box through a spiral dust collector, eliminating the need to replace the filter element and reducing maintenance costs.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1 Please see Figure 1-6 A dust removal structure for photovoltaic panels used in new energy photovoltaic and wind power includes a walking track 1 fixedly installed on the frame of the photovoltaic panel and a walking frame 2 installed on the walking track 1. Dust collection boxes 3 and compressed air sources 4 are respectively installed at both ends of the top of the walking frame 2. A dust removal mechanism 5 is installed inside the walking frame 2. The dust removal mechanism 5 includes a negative pressure suction pipe 51 and two blowing pipes 52 installed inside the walking frame 2. The two blowing pipes 52 are symmetrically distributed on both sides of the negative pressure suction pipe 51. A dust collection channel 53 is provided at the top of the blowing pipe 52. Two arc-shaped guide plates 54 are fixedly connected to both ends of the dust collection channel 53, forming a guide channel between two adjacent guide plates 54. The negative pressure suction pipe 51 has multiple series-connected contraction sections 55 along its length. Several suction pipes 56 are spaced apart at the top of the dust collection channel 53 along its length. The other end of the suction pipes 56 is connected to the contraction sections 55. A mounting plate 57 is fixedly connected above the dust collection channel 53. Multiple spaced vibrating devices are bolted to the front side of the mounting plate 57 along its length. The stripping component 58, through the sand and dust cleaning mechanism 5, supplies air from the compressed air source 4 to the two blowing pipes 52. The airflow from the blowing pipes 52 blows the sand and dust away from the panel surface and is guided by the arc-shaped guide plates 54 at both ends of the dust collection channel 53. The airflow containing sand and dust passes through the guide channel between the two guide plates 54 and enters the dust collection channel 53, where it is sucked away by the negative pressure suction pipe 51. At the same time, the vibration stripping component 58 applies high-frequency micro-amplitude vibration to the panel surface to assist in loosening and falling off the sand and dust. Through this cleaning method of vibration pre-stripping, airflow guidance, and distributed negative pressure suction, non-contact, dust-free photovoltaic panel surface cleaning is achieved. It has the advantages of not damaging the photovoltaic panel surface, no secondary dust, good cleaning effect, and is suitable for the operation and maintenance of new energy photovoltaic equipment.

[0030] The vibration stripping assembly 58 includes a mounting frame 581, a flexible pad 582 at the bottom of the mounting frame 581, and multiple vibration springs 583 between the flexible pad 582 and the mounting frame 581. A housing 584 is bolted to the top of the mounting frame 581, and an end cap 585 is bolted to the left side of the housing 584. A rolling groove 586 is formed inside the housing 584, and a central column 587 is provided inside the rolling groove 586. A track ring 588 is fixedly fitted onto the surface of the central column 587, and a ball bearing 589 is provided inside the track ring 588. The surfaces of the ball bearings 589 are in contact with the rolling groove 586 and the track ring 588, respectively. The tops of both ends of the housing 584 are respectively provided with... Air inlet 7 and air outlet 8 are connected to rolling groove 586. By setting up vibration peeling component 58, compressed air enters the rolling groove 586 in the housing 584 through air inlet 7, driving the ball bearings 589 in the track ring 588 to circulate at high speed along the rolling groove 586. The ball bearings 589 generate high-frequency vibration during the rolling process, which is transmitted through the housing 584 to the mounting bracket 581 and flexible pad 582, and finally to the surface of the photovoltaic panel. The vibration spring 583 buffers and adjusts the vibration amplitude, so that the vibration energy transmitted to the panel is moderate, which can effectively peel off sand and dust without causing impact damage to the photovoltaic panel, and achieve the effect of loosening and falling off sand and dust.

[0031] The housing 584 has an air inlet pipe 9 and a silencer 10 at the top of each end. The air inlet pipe 9 and the silencer 10 are connected to the air inlet slot 7 and the air outlet slot 8, respectively. The left end of the blow-off pipe 52 is fixedly connected to a branch pipe. The end of the air inlet pipe 9 near the branch pipe is fixedly connected to the branch pipe. The blow-off pipe 52 supplies air to the vibration stripping assembly 58 through the branch pipe and the air inlet pipe 9, so that the vibration stripping and the blow-off dust collection share the same compressed air source 4, eliminating the need for an independent power source. The silencer 10 effectively reduces the noise of the vibration stripping assembly 58 during operation and improves the working environment.

[0032] The mounting frame 581 is equipped with a connecting frame 11 on its top. The mounting frame 581 is bolted to the mounting plate 57 through the connecting frame 11. Multiple damping vibration isolators are provided between the mounting frame 581 and the connecting frame 11, which are spaced apart along the length direction. The vibration of the vibration stripping component 58 is isolated from the walking frame 2 by the damping vibration isolators, so as to avoid vibration interference with the stable operation of the walking mechanism, reduce the fatigue damage of vibration to the frame and other components, and extend the service life of the equipment.

[0033] The walking frame 2 is equipped with multiple bidirectional lead screws 12, which are bolted together. Two first internal thread blocks 13 are threaded onto the surface of the bidirectional lead screw 12. The bottom end of the first internal thread block 13 is rotatably connected to a connecting rod 14. The other end of the connecting rod 14 is rotatably connected to the mounting plate 57. The bidirectional lead screw 12 is driven to rotate by a drive motor pre-installed inside the walking frame 2, which causes the two first internal thread blocks 13 on the bidirectional lead screw 12 to move towards or away from each other. The first internal thread blocks 13 drive the mounting plate 57 to rise and fall through the connecting rod 14, thereby adjusting the distance between the dust cleaning mechanism 5 and the photovoltaic panel surface to meet the cleaning needs of photovoltaic panels of different thicknesses or different installation heights. Furthermore, the adjacent bidirectional lead screws 12 are bolted together to achieve synchronous rotation, ensuring that both ends of the mounting plate 57 rise and fall synchronously.

[0034] The bottom of both ends of the walking frame 2 is bolted with a drive wheel walking mechanism 15. The drive wheel walking mechanism 15 is located inside the walking track 1 and works in conjunction with it. Support wheels 16 are bolted to the middle of the front and rear sides of the walking frame 2. The support wheels 16 are located on the edges of two adjacent photovoltaic panels. The cooperation between the drive wheel walking mechanism 15 and the walking track 1 ensures precise guidance of the walking. The design of the support wheels 16 spanning the edges of adjacent photovoltaic panels allows the walking frame 2 to smoothly cross the gaps between the panels, ensuring walking stability.

[0035] The walking frame 2 is rotatably connected to both ends of a screw 17. A second internal thread block 18 is threaded onto the surface of the screw 17. A sliding frame 19 is fixedly connected to both ends of the second internal thread block 18. A limit wheel 20 is fixedly connected to the bottom end of the sliding frame 19. The limit wheel 20 rolls in contact with the walking track 1. When the operator rotates the screw 17, the second internal thread block 18 moves axially along the screw 17. The second internal thread block 18 drives the sliding frame 19 and the limit wheel 20 to move synchronously, adjusting the contact position and pressure between the limit wheel 20 and the walking track 1 to ensure the stable operation of the walking frame 2 on the track and prevent walking deviation or shaking caused by poor contact.

[0036] The sliding frame 19 has a guide post 21 running through it, and both ends of the guide post 21 are fixedly connected to the inner wall of the walking frame 2. The guide post 21 running through the sliding frame 19 can provide linear guidance for the sliding frame 19, ensuring the linearity and stability of the movement of the limit wheel 20.

[0037] Working principle of this embodiment: When the dust removal mechanism 5 is working, the walking frame 2 moves along the walking track 1 on the photovoltaic panel frame to the starting position of the cleaning. The compressed air source 4 is started, supplying air to the two blowing pipes 52 symmetrically distributed on both sides of the negative pressure suction pipe 51. At the same time, air is supplied to the housing 584 of the vibration stripping component 58 through the branch pipe and the air inlet pipe 9. The compressed air enters the rolling groove 586 in the housing 584 through the air inlet groove 7, driving the ball bearings 589 in the track ring 588 to circulate at high speed along the rolling groove 586. The ball bearings 589 generate high-frequency vibration during the rolling process, which is transmitted to the mounting frame 581 and the flexible pad 582 through the housing 584, and finally to the surface of the photovoltaic panel. The vibration spring 583 buffers and adjusts the vibration amplitude, so that the vibration energy transmitted to the panel surface is moderate. Under the action of continuous high-frequency micro-amplitude vibration, the adhesion interface between the dust and the panel surface undergoes fatigue damage, and the dust loosens and falls off. At the same time, the two blowing pipes 584... 2. The output airflow flows along both sides of the cleaning area and is guided by the arc-shaped guide plates 54 at both ends of the dust collection channel 53, forming a directional air curtain on the photovoltaic panel surface. The dust that has been shaken off is guided from both sides to the central dust collection area. The airflow containing dust enters the dust collection channel 53 through the guide channel between two adjacent guide plates 54. The negative pressure suction pipe 51 is provided with multiple series-connected contraction sections 55 along its length. Each contraction section 55 is connected to the dust collection channel 53 through an independent suction pipe 56. When compressed air flows through each contraction section 55, a local negative pressure is generated in the contraction section 55. The dust-laden airflow in the dust collection channel 53 is sucked into the negative pressure suction pipe 51 through the suction pipe 56. Each contraction section 55 generates negative pressure independently without interfering with each other, so that the suction force of the negative pressure suction pipe 51 is uniform throughout its entire length. Finally, the dust-laden airflow is transported to the dust collection box 3 through the negative pressure suction pipe 51 for subsequent separation processing, completing the cleaning and collection of dust on the photovoltaic panel surface.

[0038] Example 2 refer to Figure 7-8A dust removal structure for photovoltaic panels used in new energy photovoltaic and wind power also includes a dust separation component 6. The dust separation component 6 includes a collection cylinder 61, with a spiral dust collector 62 located on the left side of the collection cylinder 61. The other end of the spiral dust collector 62 extends to the outside of the dust collection box 3. A conical separation cylinder 63 is fixedly connected to the top of the collection cylinder 61. A connecting pipe 64 is fixedly connected to the left end of a negative pressure suction pipe 51. The other end of the connecting pipe 64 is connected to the tangential inlet pipe of the conical separation cylinder 63. A central pipe 65 is located at the top of the conical separation cylinder 63. The top of the central pipe 65 extends to the outside of the conical separation cylinder 63 and is connected to a clean air outlet pipe 66. The other end of the clean air outlet pipe 66 is connected to the air inlet of a compressed air source 4. The central pipe 65... The unit is equipped with a secondary separation unit 67. Through the sand and dust separation component 6, the dust-laden airflow enters the connecting pipe 64 through the negative pressure suction pipe 51, and enters the conical separation cylinder 63 from the tangential inlet pipe. The dust-laden airflow rotates at high speed in the conical separation cylinder 63. Larger sand and dust particles are thrown towards the cylinder wall under the action of centrifugal force, spiral down along the wall and enter the collection cylinder 61. They are discharged from the dust collection box 3 by the spiral dust discharger 62. The clean airflow after primary separation rises into the central pipe 65. After further purification by the secondary separation unit 67, it flows back from the clean air outlet pipe 66 to the air inlet pipe 9 of the compressed air source 4, realizing the separation and collection of sand and dust, avoiding pollution of the environment and photovoltaic panel surface. Moreover, the clean air flowing back to the compressed air source 4 reduces the consumption of compressed air and improves energy utilization efficiency.

[0039] The secondary separation unit 67 includes a perforated plate 671 rotatably connected inside the central tube 65. An annular filter screen 672 is fixedly installed at the bottom of the perforated plate 671. An annular dust guide plate 673 is installed inside the annular filter screen 672. The bottom end of the annular dust guide plate 673 is flush with the central tube 65, and an annular dust guide gap is formed between the annular dust guide plate 673 and the inner wall of the central tube 65. A rotating shaft 674 is bolted to the bottom of the perforated plate 671, and a rotating blade 675 is bolted to the bottom end of the rotating shaft 674. A rotating blade 675 is bolted to the inner side of the annular dust guide plate 673. A bracket 676 is rotatably mounted on the surface of a rotating shaft 674. Several striking rods 677 are spaced circumferentially at the top of the inner surface of the annular dust guide plate 673. The striking rods 677 are slidably connected to the annular dust guide plate 673. A tension spring 678 is sleeved on the surface of each striking rod 677, with both ends connected to the striking rod 677 and the annular dust guide plate 673, respectively. The end of the striking rod 677 closest to the annular filter screen 672 contacts the annular filter screen 672. Multiple protrusions are circumferentially arranged at the bottom inner side of the annular filter screen 672. The device works in conjunction with the striking rod 677. Through the secondary separation unit 67, the airflow after primary separation enters the central tube 65, driving the rotating blade 675 to rotate. The rotating blade 675, via the rotating shaft 674, drives the perforated plate 671 and the annular filter screen 672 to rotate, ensuring full and comprehensive contact between the annular filter screen 672 and the airflow, allowing for secondary filtration of residual fine dust in the airflow. Simultaneously with the rotation of the rotating shaft 674, a protrusion at the bottom inner side of the annular filter screen 672 periodically pushes the striking rod 677 outwards. Under the action of the tension spring 678, 677 rebounds and strikes the annular filter screen 672, shaking off the dust attached to the filter screen and discharging it through the annular guide gap between the annular dust guide plate 673 and the central tube 65. This secondary separation component uses the kinetic energy of the airflow itself to drive the rotating blade 675 to rotate, which in turn drives the annular filter screen 672 to rotate for secondary filtration. No additional power source is required, and the cooperation between the striking rod 677 and the protrusion enables the filter screen to self-clean online, avoiding filter screen clogging and ensuring the continuous effectiveness of secondary separation.

[0040] The working principle of this embodiment is as follows: The dust-laden airflow enters the connecting pipe 64 through the negative pressure suction pipe 51, and then enters the conical separation cylinder 63 through the tangential inlet pipe. The dust-laden airflow rotates at high speed tangentially inside the conical separation cylinder 63, generating a centrifugal force field. Larger dust particles are thrown against the cylinder wall under the action of centrifugal force and spiral down along the wall into the collection cylinder 61, where they are periodically discharged from the dust collection box 3 by the spiral dust discharger 62. The clean airflow after primary centrifugal separation rises into the central pipe 65, driving the rotating blade 675 to rotate. The rotating blade 675 drives the perforated plate 671 and the annular filter screen 672 to rotate synchronously through the rotating shaft 674. The annular filter screen 672 performs secondary filtration of residual fine dust in the airflow and also acts as an annular dust guide. Plate 673 guides the filtered dust to the annular dust guide gap for discharge; when the rotating shaft 674 rotates, multiple protrusions arranged circumferentially at the bottom inner side of the annular filter screen 672 periodically push the striking rod 677 to slide radially outward. The striking rod 677 rebounds rapidly under the action of the tension spring 678, applying high-frequency knocking to the annular filter screen 672, shaking off the dust attached to the filter screen. The shaken-off dust is discharged through the annular dust guide gap between the annular dust guide plate 673 and the inner wall of the central tube 65, realizing online self-cleaning of the filter screen; the clean air after secondary separation enters the clean air outlet pipe 66 from the top of the central tube 65 and flows back to the air inlet of the compressed air source 4, realizing the recycling of compressed air.
