Description

Technical Field

[0001] The present invention relates to the field of photovoltaic cleaning, and in particular to photovoltaic intelligent cleaning equipment. Background Art

[0002] Photovoltaic power station is a green energy project. Multiple photovoltaic panels are installed in the photovoltaic power station. When the photovoltaic panels are exposed to the sun, they will generate electric current to achieve the effect of power generation. However, the photovoltaic panels are exposed to the air for a long time and are prone to accumulate excessive dust. The dust on the photovoltaic panels needs to be scraped and cleaned to increase the service life of the photovoltaic panels. At present, in the existing photovoltaic panel cleaning equipment used in photovoltaic power stations, it is necessary to manually adjust the angle of the photovoltaic panels, and it is also necessary to manually scrape the dust and clean the dust and impurities on the photovoltaic panels, which increases the labor intensity of the workers. In addition, the equipment cannot be well positioned, and the stability is poor, causing the equipment to shake easily, affecting the working efficiency of the photovoltaic panels, and other problems.

[0003] The currently disclosed Chinese patent CN114453294A discloses an automatic cleaning device for photovoltaic panels used in photovoltaic power station construction, which includes: a support frame; universal wheels, which are symmetrically rotatably provided on both sides of the bottom of the support frame; a buffer plate, which is slidably provided in the middle of the top of the support frame; a first spring, which is symmetrically provided between the lower side of the buffer plate and the upper side of the inner part of the support frame; a placement plate, which is rotatably provided on the top of the buffer plate; a scraper, which is slidably provided on one side of the top of the placement plate; an adjustment component, which is provided between the placement plate and the support frame; a water spray component, which is provided between one side of the top of the support frame and one side of the placement plate; and a clamping component, which is provided on the placement plate.

[0004] According to the above-mentioned patent, the scraper and the brush move back and forth up and down, and the scraper can scrape off the impurities on the photovoltaic panel. The rotation of the first gear will drive the brush to rotate, so that the brush cleans the photovoltaic panel, achieving the effect of automatically scraping off impurities and automatically cleaning. However, the patent cannot adjust the cleaning pressure for cleaning the photovoltaic panel. If the pressure is too high, the photovoltaic panel will easily dent, and if the pressure is too low, the dirt on the photovoltaic panel cannot be completely cleaned.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figure 1-Figure 6 As shown, the photovoltaic intelligent cleaning equipment includes a shell 1 arranged on the surface of the photovoltaic panel 8 and a support frame 2 for supporting the photovoltaic panel 8, the shell 1 is provided with a brush 3 and a sponge roller 4 parallel to each other, the support frame 2 is provided with a moving component 21 for driving the shell 1 to move along the edge of the photovoltaic panel 8, a nozzle 11 and a scraper 12 are respectively provided on both sides of the moving direction of the shell 1, the brush 3 and the sponge roller 4 can move synchronously in the shell 1 along the direction of the photovoltaic panel 8, a lifting frame 5 connected to the brush 3 and the sponge roller 4 is provided in the shell 1, the lifting frame 5 is provided with a driving component 51 for synchronously driving the brush 3 and the sponge roller 4 to operate, upper pressure control components 6 for controlling the downward pressure of the lifting frame 5 are provided on both sides of the shell 1, and a lower buffer component 7 for buffering the photovoltaic panel 8 is provided on the support frame 2.

[0032] The moving assembly 21 includes a guide rail 211 fixedly connected to the support frame 2 and an electric control guide wheel 212 rotatably connected to the housing 1. The electric control guide wheel 212 mainly includes a driving motor, a guide wheel and a bracket. The guide wheel is driven by the motor to rotate, so that the guide wheel rotates, and the electric control guide wheel 212 rolls on the guide rail 211, and the housing 1 translates along the photovoltaic panel 8, so that the brush 3 and the sponge roller 4 move together to brush the photovoltaic panel 8; The driving assembly 51 is provided with a pulley 511 coaxially fixedly connected with the brush 3 and the sponge roller 4, a belt 512 is connected between the pulley 511 of the brush 3 and the pulley 511 of the sponge roller 4, a synchronous wheel 513 connected to the belt 512 is provided between the two pulleys 511, and the synchronous wheel 513 is connected to the driving motor, and the driving motor drives the synchronous wheel 513 to rotate; A battery 13 is provided in the housing 1, and the battery 13 is connected to a control board 131, and the control board 131 is connected to the moving component 21 and the driving component 51. A photovoltaic panel is provided on the top of the housing 1 to provide power to the battery 13, and the battery 13 can also be charged externally to directly charge the battery 13; When the photovoltaic panel 8 needs to be cleaned, the housing 1 is driven by the moving component 21 to move along the surface of the photovoltaic panel 8. During the movement, the nozzle 11 sprinkles water on the surface of the photovoltaic panel 8 to moisten the surface of the photovoltaic panel 8 and wet the sundries dried on the surface of the photovoltaic panel 8, thereby improving the cleaning effect on the surface of the photovoltaic panel 8. The driving component 51 drives the brush 3 and the sponge roller 4 to rotate synchronously. The brush 3 is closely attached to the surface of the photovoltaic panel 8 for brushing, and the sponge roller 4 wipes off the water stains to ensure that the surface of the photovoltaic panel 8 is in a dry state after cleaning. The scraper 12 further scrapes the dirt on the surface of the photovoltaic panel 8. In order to achieve the cleaning effect and prevent some difficult-to-remove dirt from remaining on the surface of the photovoltaic panel 8, in order to ensure that the photovoltaic panel 8 is subjected to stable pressure from the brush 3 and the sponge roller 4, the upper pressure control component 6 is used to control the lifting frame 5 to approach the support frame 2 until the brush 3 and the sponge roller 4 are adjusted to a state of stable pressure against the photovoltaic panel 8. In order to prevent the photovoltaic panel 8 from being deformed by pressure, the lower buffer component 7 is used to buffer the pressure on the photovoltaic panel 8. Under the action of the upper pressure control component 6 and the lower buffer component 7, the brush 3 and the sponge roller 4 can stably squeeze the photovoltaic panel 8 to achieve an effective cleaning effect.

[0033] See also Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, the upper control pressure assembly 6 includes a guide rod 61 and a sleeve 62. The guide rod 61 is fixed on the shell 1 in a vertical state. The sleeve 62 is slidably mounted on the guide rod 61. An extension plate 621 is fixedly connected between the sleeve 62 and the lifting frame 5. A sliding opening for the extension plate 621 to slide is vertically opened on the shell 1. A first compression spring 611 mounted on the guide rod 61 is fixedly connected between the sleeve 62 and the lower end of the guide rod 61. A positioning member 63 connected to the extension plate 621 is provided on the outer side of the shell 1. When the first compression spring 611 is in a normal state, the brush 3 and the sponge roller 4 are in a state of moving out of the lower end of the shell 1. A second compression spring 612 mounted on the guide rod 61 is provided between the sleeve 62 and the upper end of the guide rod 61. The lower end of the second compression spring 612 is fixedly connected to the sleeve 62, and the upper end of the second compression spring 612 is connected to an extrusion member 64.

[0034] When the shell 1 has not passed the photovoltaic panel 8, the brush 3 and the sponge roller 4 are in the shell 1 under the control of the positioning member 63. The first compression spring 611 is in a stretched state. As the shell 1 passes the photovoltaic panel 8, the positioning member 63 releases the restriction on the lifting frame 5, so that the first compression spring 611 gradually returns to a normal state. At this time, the brush 3 and the sponge roller 4 are supported on the surface of the photovoltaic panel 8. As the shell 1 continues to move, in order to ensure that the brush 3 and the sponge roller 4 have a stable pressure on the photovoltaic panel 8 and to ensure that the surface of the photovoltaic panel 8 is effectively cleaned, pressure is applied to the second compression spring 612 through the extrusion member 64, and the pressure on the second compression spring 612 is transmitted to the sleeve 62, thereby maintaining the lifting frame 5 in a stable state relative to the photovoltaic panel 8, providing cleaning force, and improving the cleaning effect.

[0035] See also Figure 7-Figure 9 As shown, the positioning member 63 is provided with a side plate 631, which is slidably arranged on the outer side of the shell 1, and the sliding direction of the side plate 631 is parallel to the sliding direction of the shell 1. The side plate 631 is provided with a plane groove 6311 and a bevel groove 6312 for the extension plate 621 to slide and engage therein, and the plane groove 6311 and the bevel groove 6312 are in a connected state. Specifically, a horizontal section and an inclined section are provided on the side plate 631, and the plane groove 6311 and the bevel groove 6312 are opened on the upper surface of the horizontal section and the inclined section, so that the extension plate 621 moves along the upper surface of the horizontal section and the inclined section. When the extension plate 621 is in the position of the plane groove 6311, the first compression spring 611 is in a stretched state and the brush 3 and the sponge roller 4 are in the shell 1. When the extension plate 621 is in the position of the bevel groove 6312, the first compression spring 611 is in a gradually returning to a normal state so that the brush 3 and the sponge roller 4 move toward the outside of the shell 1.

[0036] The housing 1 is provided with a screw 632 for pushing the side plate 631 to slide. One end of the screw 632 is fixedly connected to a driving motor to drive the screw 632 to rotate. A slider 6321 is threadedly sleeved on the screw 632. The housing 1 is provided with a slide rail 6322 for the slider 6321 to slide. The slider 6321 is fixedly connected to the pushing side plate 631. As the extension plate 621 is supported on the flat groove 6311 of the side plate 631, the first compression spring 611 is in a stretched state. When the outer shell 1 passes through the photovoltaic panel 8, the side plate 631 moves, causing the extension plate 621 to move along the inclined groove 6312. The first compression spring 611 gradually returns to a normal state until the side plate 631 is away from the extension plate 621. The brush 3 and the sponge roller 4 are thereby supported on the surface of the photovoltaic panel 8, thereby achieving effective pressure of the brush 3 and the sponge roller 4 on the photovoltaic panel 8, thereby avoiding the situation where the brush 3 and the sponge roller 4 are blocked by the side of the photovoltaic panel 8 when the outer shell 1 passes by.

[0037] See also Figure 7-Figure 9 As shown, the extrusion member 64 includes a sleeve 641, which is slidably mounted on the guide rod 61, and the lower end of the sleeve 641 is fixedly connected to the second compression spring 612. The housing 1 is provided with an electric push rod 642 for pushing the sleeve 641 to move.

[0038] When the brush 3 and the sponge roller 4 are supported on the surface of the photovoltaic panel 8, the second compression spring 612 is in a normal state, and the sleeve 641 is pushed on the guide rod 61 by the electric push rod 642 to approach the sleeve 62, thereby gradually compressing the second compression spring 612 and the first compression spring 611 below. The compression force of the second compression spring 612 is transmitted to the sleeve 62, thereby achieving the effect of stable pressure of the brush 3 and the sponge roller 4 on the photovoltaic panel 8, controlling the distance of the sleeve 641 close to the sleeve 62, thereby controlling the pressure of the brush 3 and the sponge roller 4 on the photovoltaic panel 8, and ensuring that the surface of the photovoltaic panel 8 is effectively cleaned.

[0039] See also Figure 7-Figure 9 As shown, a swing rod 643 is provided on the side of the sleeve 641, one end of the swing rod 643 is rotatably connected to the housing 1, and the other end of the swing rod 643 extends toward the sleeve 641. The middle part of the sleeve 641 has a convex shaft 6411 extending outward, and the end of the swing rod 643 extending toward the sleeve 641 is provided with a groove 6431 for clamping the convex shaft 6411 therein, and the output end of the electric push rod 642 is opposite to the upper surface of the swing rod 643. When the sleeve 641 moves following the sliding sleeve 62, the swing rod 643 is in a swinging state together.

[0040] When the sleeve 641 moves with the sliding sleeve 62, the sleeve 641 is connected with the slot 6431 on the swing rod 643 through the convex shaft 6411, so that the movement of the sleeve 641 drives the swing rod 643 to swing, until the swing rod 643 stops swinging, and then the swing rod 643 is pushed by the electric push rod 642, so that the swing rod 643 swings downward, thereby driving the sleeve 641 to approach the sliding sleeve 62, and the second compression spring 612 is gradually compressed, and the extrusion force is controlled by the electric push rod 642.

[0041] See also Figure 7-Figure 9 As shown, a pressure sensor for detecting the pressure level of the second compression spring 612 is provided between the sleeve 641 and the sliding sleeve 62 .

[0042] Since the pressure sensor is a prior art, the pressure sensor is not shown in the figure. When the first compression spring 611 is relaxed, the first compression spring 611 gradually returns to a normal state, allowing the brush 3 and the sponge roller 4 to contact the surface of the photovoltaic panel 8. The first compression spring 611 provides pressure. In order to further control the pressure of the brush 3 and the sponge roller 4 on the photovoltaic panel 8, the second compression spring 612 is squeezed by the extrusion piece 64, and the pressure of the second compression spring 612 is transmitted to the sleeve 62. The pressure on the sleeve 62 is then transmitted to the brush 3 and the sponge roller 4. The pressure level of the second compression spring 612 is known through the pressure sensor, and the extrusion force of the extrusion piece 64 is controlled to ensure that the photovoltaic panel 8 is subjected to stable pressure, thereby improving the cleaning effect.

[0043] See also Figure 2 and Figure 3 As shown, the lower buffer assembly 7 is provided with a cushion layer 71 laid on the top edge of the support frame 2 for supporting the photovoltaic panel 8 .

[0044] The cushion layer 71 reduces the wear of the photovoltaic panel 8 and provides buffering and supporting forces, which helps to keep the photovoltaic panel 8 in a compressed and buffered state during the cleaning process, improves the cleaning effect of the photovoltaic panel 8, reduces the risk of damage, and makes the cleaning of the photovoltaic panel 8 safer and more reliable.

[0045] See also Figure 2-Figure 4 As shown, the lower buffer assembly 7 is also provided with a central axis 72 and a sliding frame 73, one end of the central axis 72 is fixedly connected to the center of the support frame 2, the other end of the central axis 72 extends downwardly in a manner perpendicular to the support frame 2, the sliding frame 73 is slidably mounted on the central axis 72, the sliding frame 73 is parallel to the support frame 2, the lower end of the central axis 72 is sleeved with an anti-slip ring 721, and a buffer spring 722 sleeved on the central axis 72 is fixedly connected between the anti-slip ring 721 and the sliding frame 73, and a suction cup 731 is provided around the sliding frame 73 for keeping the photovoltaic panel 8 in a stable state.

[0046] The photovoltaic panel 8 is supported by a cushion layer 71. Since the cushion layer 71 is a soft structure, in order to ensure the stability of the photovoltaic panel 8, suction cups 731 are arranged around the support frame 2 to maintain the stability of the photovoltaic panel 8 and prevent the photovoltaic panel 8 from shaking. The sliding frame 73 is slidably arranged on the central axis 72, which limits the range of movement of the sliding frame 73 and can only maintain a vertical movement state with the support frame 2. Through the setting of the buffer spring 722, the pressure of the brush 3 and the sponge roller 4 on the photovoltaic panel 8 can be buffered, thereby providing the best cleaning effect and protecting the photovoltaic panel 8 from damage.

[0047] See also Figure 5 As shown, a water tank 111 is provided in the housing 1 for providing water to the nozzle 11 , and a water pump 1111 is connected between the water tank 111 and the nozzle 11 .

[0048] When the shell 1 moves along the surface of the photovoltaic panel 8, the water tank 111 provides water to the nozzle 11, and the water pump 1111 ensures that the nozzle 11 can obtain sufficient water pressure to effectively clean the surface of the photovoltaic panel 8, and combines with the brush 3 and the sponge roller 4 to ensure that the surface of the photovoltaic panel 8 is effectively cleaned.

[0049] See also Figure 6 and Fig.10 As shown, the length direction of the scraper 12 is perpendicular to the moving direction of the shell 1, and both sides of the scraper 12 have an axial connection portion 121. The shell 1 has an axial connection seat 1211 for connecting the axial connection portion 121. A torsion spring 122 is fixedly connected between the axial connection portion 121 and the axial connection seat 1211. When the torsion spring 122 is in a normal state, the scraper 12 is in a drooping state.

[0050] When the shell 1 moves along the surface of the photovoltaic panel 8, the scraper 12 contacts the surface of the photovoltaic panel 8. At this time, the torsion spring 122 is in a torsion state. The torsion spring 122 provides the scraper 12 with a resistance force on the photovoltaic panel 8, ensuring that the scraper 12 can scrape off the dirt on the surface of the photovoltaic panel 8, thereby improving the cleaning effect of the surface of the photovoltaic panel 8.

[0051] The present invention controls the pressure of the brush 3 and the sponge roller 4 on the photovoltaic panel 8 through the upper pressure control component 6, and reduces the pressure of the brush 3 and the sponge roller 4 on the photovoltaic panel 8 through the lower buffer component 7, so that the photovoltaic panel 8 can achieve an effective cleaning effect without being damaged, improves the cleaning effect, ensures the quality of the photovoltaic panel 8, and thus ensures that the use effect of the photovoltaic panel 8 remains normal after cleaning.

[0052] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
