Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and in particular relates to a cleaning mechanism and a photovoltaic power generation device with the cleaning mechanism installed on top. Background Art

[0002] Solar photovoltaic power generation is a new type of green renewable resource that is widely used in production and life. During the use of existing solar photovoltaic modules, impurities and garbage on the surface of the photovoltaic modules will accumulate on the surface of the solar photovoltaic panels if they are not cleaned for a long time, affecting the energy absorption and power generation effect of the solar photovoltaic modules. Therefore, it is necessary to clean the impurities and dust accumulated on the surface of the photovoltaic modules during use to keep the surface of the solar photovoltaic panels clean.

[0003] For example, CN115632610A discloses a photovoltaic panel cleaning device. When the photovoltaic panel cleaning device is working, the rotating disk first drives the first connecting rod to move the first connecting frame relative to the photovoltaic panel. During this process, the rotation direction of the position where the first brush roller contacts the photovoltaic panel is the same as the movement direction of the first brush roller, which can greatly increase the force of the first brush roller on the dust, thereby enhancing the cleaning effect, so as to ensure that the surface of the photovoltaic panel is continuously kept clean, thereby improving the photovoltaic panel to have a high working efficiency under the condition of long-term unattended management. When the first brush roller is used to clean the surface of the photovoltaic panel, dust will be adsorbed on the first brush roller, and then when it rains during use, the dust adhered to the first brush roller will agglomerate, thereby causing the first brush roller that causes agglomeration to lose its cleaning function during use. At the same time, as the first brush roller moves back and forth on the surface of the photovoltaic panel, the dust remaining on the first brush roller will re-attach to the surface of the photovoltaic panel, thereby causing the photovoltaic panel to be not thoroughly cleaned during use.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0036] like Figure 1-2 As shown in Figure 10, the present invention provides a photovoltaic power generation device. When installing the photovoltaic power generation device, a foundation 100 is formed by pouring concrete on the installation ground in advance, and then a supporting structure 2 is fixed on the foundation 100. Finally, the solar cell module array 1 is installed on the top of the supporting structure 2, and the solar cell module array 1 is kept in an inclined state as a whole after installation. A cleaning mechanism 5 and a dust detection module for detecting dust on the surface of the solar cell module array 1 are provided on the upper surface of the solar cell module array 1. The dust detection module and the cleaning mechanism 5 are both connected to a controller. When it is detected that there is enough dust on the surface of the solar cell module array 1 during use, the cleaning mechanism 5 is controlled to move up and down parallel to the upper surface of the solar cell module array 1, and then the cleaning mechanism 5 is used to clean the dust on the surface of the solar cell module array 1.

[0037] Specifically, Fig.10 The supporting structure 2 includes a supporting column 20, the top of which is connected to a supporting structure formed by a longitudinal beam 21 and a transverse beam 22; a tie rod 23 is connected between two adjacent supporting columns 20; and the solar cell assembly array 1 adopts a solar cell panel layout of M rows and N columns, and the bottom end of the supporting column 20 is fixed on a concrete foundation 100.

[0038] Specifically, in order to facilitate the control of the cleaning mechanism 5 to move up and down along the upper surface of the parallel solar cell assembly array 1, a traction mechanism connected to the cleaning mechanism 5 and used to drive the cleaning mechanism to move up and down along the upper surface of the parallel solar cell assembly array 1 is also provided.

[0039] In order to facilitate the control of the cleaning mechanism 5 to move up and down along the upper surface of the solar cell module array 1 under the action of the traction mechanism, the present invention installs a supporting main beam 3 on the supporting structure 2 located on both sides of the solar cell module array through pillars, and the supporting main beam 3 is parallel to the upper surface of the solar cell module array 1 and protrudes from the upper surface of the solar cell module array 1. A rectangular hole 301 is opened on one side of the supporting main beam 3 along its length direction, such as Figure 4, rectangular grooves A302 are respectively provided on the opposite side walls of the rectangular hole 301; at the same time, the cleaning mechanism 5 includes a U-shaped groove plate 51, and the two ends of the U-shaped groove plate 51 are respectively connected to a slider 57 through a connecting column 56, and the slider 57 extends into the rectangular hole 301 and can slide along the length direction of the rectangular groove A302, and a brush structure including a strip brush 541 is provided on the inner side of the U-shaped groove plate 51, so that when in use, the U-shaped groove plate 51 can be used to move up and down parallel to the upper surface of the solar cell component array 1, and the dust on the upper surface of the solar cell component array 1 can be cleaned by using the brush structure.

[0040] Based on the above, it should be noted that in the process of using the brush structure to clean the dust on the surface of the solar cell module array 1 for a long time, dust will adhere to the bristles of the brush structure. The dust adhered to the bristles will agglomerate when it rains, and then due to the agglomeration of water absorption or too much dust adhering to the bristles, the solar cell module array 1 will not be cleaned thoroughly when the brush structure is used again to clean. In order to solve the above problem, a downwardly inclined U-shaped cover 4 is fixed between the tops of the two supporting main beams 3. A scraper 6 is fixed between the tops of the two supporting main beams 3; the U-shaped cover 4 is used to shield the brush structure during use to prevent rainwater from soaking the bristles and causing dust and other lumps to adhere to the bristles; at the same time, the scraper 6 is set to control the brush structure to move up and down near the scraper during use, and then the scraper 6 is controlled to contact and rub the brush structure back and forth, thereby removing dust adhered to the bristles during the cleaning process; that is, in the present invention, the U-shaped cover 4 and the scraper 6 are set to maintain the cleanliness of the brush structure itself and improve the cleaning effect.

[0041] Specifically, the scraper 6 includes a rectangular plate body, and a plurality of protrusions are evenly distributed on the scraper 6. When in use, the protrusions are used to pass through the gaps between the bristles to clean the brush structure.

[0042] It is known that if Figure 7 In order to improve the cleaning effect of the cleaning mechanism 5 on the dust on the surface of the solar cell module array 1 during use, a water spray pipe 52 and an air jet pipe 53 are respectively arranged on the two outer side walls of the U-shaped groove plate 51, and a plurality of water spray nozzles 521 and air jet nozzles 521 are respectively arranged along the length direction of the water spray pipe 52 and the air jet pipe 53 close to the solar cell module array 1; and the water flow and air flow directions of the above-mentioned water spray nozzles 521 and air jet nozzles 521 are both gathered toward the middle part of the U-shaped groove plate 51.

[0043] Specifically, based on the settings of the water spray pipe 52 and the air jet pipe 53, it is possible to choose whether to use the water spray pipe 52 to impact the upper surface of the solar cell component array 1, or to use the air jet pipe 53 to purge the upper surface of the solar cell component array 1 according to actual cleaning needs during use, and then use the purge to blow away the dust brought up by the brush structure, thereby improving the cleaning effect of the dust on the upper surface of the solar cell component array 1 during use.

[0044] It should be noted that when the brush structure is used to clean the dust on the upper surface of the solar cell module array 1, when the water flow of the water spray pipe 52 is used to impact the upper surface of the solar cell module array 1, the water flow formed at this time is easy to directly impact the brush structure. Therefore, when the water flow of the water spray pipe 52 is used to impact the upper surface of the solar cell module array 1, it is necessary to control the brush structure to be stored in the U-shaped groove plate 51. For the purpose of secondary storage needs, such as Figure 5 , female buckles 511 and male buckles 512 of mutually cooperating press-type spring buckles are respectively arranged on the opposite sides of the U-shaped groove plate 51 and the base plate 54, and a plurality of telescopic cylinders 42 are arranged on the inner side of the U-shaped cover 4 below the U-shaped groove plate 51, and the ends of the telescopic cylinders 42 are connected to the movable push plates 43; after the telescopic cylinders 42 are extended, the movable push plates 43 abut against one side of the base plate 54 located between the two strip-shaped brushes 541, and the brush structure includes a rectangular strip-shaped base plate 54, and both sides of the lower surface of the base plate 54 are A strip brush 541 is fixed, and a number of elastic telescopic modules 55 are connected between the inner bottom side of the U-shaped groove plate 51 and the base plate 54; when in use, when the telescopic cylinder 42 is controlled to extend for the first time, the male buckle 512 is controlled to be inserted into the female buckle 511, and the brush structure is controlled to be stored in the U-shaped groove plate 51; when the telescopic cylinder 42 is controlled to extend for the first time again, the male buckle 512 is detached from the female buckle 511, and the brush structure is controlled to protrude from the open end of the U-shaped groove plate 51.

[0045] The elastic telescopic module 55 includes an inner sleeve body and an outer sleeve body which are connected to each other, and a return spring is connected between the inner sleeve body and the outer sleeve body; when it is in a natural state, the cleaning mechanism 5 is stored in the U-shaped cover 4; and after completing a cleaning of the solar cell assembly array, the cleaning mechanism 5 is controlled to move up and down near the scraper 6.

[0046] It can be known that in order to facilitate the control and driving of the cleaning mechanism 5 to move up and down along the upper surface of the parallel solar cell assembly array 1, the present invention provides a through hole at both ends of the supporting main beam 3, and the opposite sides of the slider 57 are respectively connected to the traction rope A31 and the traction rope B32 connected to the traction mechanism, such as Figure 2-3The traction mechanism provided at the same time includes a motor 106 and a rotating rod 102 arranged just below the bottom of the solar cell module array 1, and a guide sleeve 33 arranged just below the top of the solar cell module array 1; the ends of the two traction ropes B32 are respectively connected to counterweight columns 38, which are located in the guide sleeve 33 and move up and down along the inner wall of the guide sleeve 33; the ends of the two traction ropes A31 are respectively connected to two winding drums 103, and the two winding drums 103 are respectively fixed at the two ends of the rotating rod 102, and the middle of the rotating rod 102 is fixed There is a gear A104; the motor 106 is installed on one side of the rotating rod 102, and the output shaft of the motor 106 is connected to a gear B107 that cooperates with the gear A104 for transmission. When the driving motor 106 is rotated during use, the winding drum 103 is used to wind up the traction rope A31, so as to facilitate the control and drive of the U-shaped groove plate 51 to move downward; when the control motor 106 stops rotating, under the action of the counterweight column 38, the U-shaped groove plate 51 is pulled upward until the cleaning mechanism 5 is stored in the U-shaped cover 4.

[0047] It should be noted that when using the above-mentioned cleaning mechanism 5 to clean the upper surface of the solar cell module array 1, it is necessary to control the cleaning mechanism 5 to reciprocate up and down multiple times along the upper surface of the solar cell module array 1 parallel to complete the cleaning of the upper surface of the solar cell module array 1. In this process, it is necessary to detect whether the cleaning mechanism 5 has moved to the topmost position and to limit the maximum extent of the downward movement of the cleaning mechanism 5. A detection module 41 for sensing whether the cleaning mechanism 5 has moved to the topmost position is provided on the inner bottom side of the U-shaped cover 4; the detection module 41 includes an outer sleeve and an inner guide rod that cooperate with each other, a spring A is connected between the outer sleeve and the inner guide rod, and a pressure sensor is provided on the bottom side of the outer sleeve through a convex column, that is, when the pressure sensor detects a pressure signal, it indicates that the cleaning mechanism 5 has moved to the topmost position.

[0048] At the same time, in order to limit the downward movement of the cleaning mechanism 5 to the maximum extent, and to control the brush structure to perform multiple up and down movements near the scraper, such as Figure 6A support ring 332 is provided on the top inner wall of one of the guide sleeves 33, and an inner guide sleeve 333 is connected to the inner wall of the support ring 332. The top peripheral side of the inner guide sleeve 333 is fixed to the top inner wall of the guide sleeve 33 through a connecting block 331, and the traction rope B32 passes through the inner guide sleeve 333; two through holes 334 are provided on the support ring 332, and the bottom side surface of the support ring 332 located at the two through holes 334 is connected to a T-shaped push rod 36 through a spring B37; a convex block 34 is provided on the inner wall of the guide sleeve 33 located directly above the T-shaped push rod 36, and the bottom side surface of the convex block 34 is connected to an elastic telescopic member 341, and the ends of the two elastic telescopic members 341 are respectively connected to a contact sensor A342 and a contact sensor B343; when the spring B37 is in a natural state, the top of the two T-shaped push rods 36 are at a distance of L1 and L2 from the contact sensor A342 and the contact sensor B343, and L2>L1.

[0049] Based on the above settings, when the driving motor 106 rotates during use, the U-shaped groove plate 51 is controlled to move downward until the U-shaped groove plate 51 is located above the scraper 6. At this time, the contact sensor B343 detects a signal, which indicates that the U-shaped groove plate 51 has completed the cleaning of the upper surface of the solar cell assembly array 1 during the downward movement; when the driving motor 106 continues to rotate, the U-shaped groove plate 51 is controlled to move downward until the U-shaped groove plate 51 is located below the scraper 6 until the contact sensor A342 detects a signal.

[0050] Then, in the above, the U-shaped groove plate 51 is controlled to move within the signal area alternately generated by the contact sensor A342 and the contact sensor B343.

[0051] Specifically, the motor 106 is installed on the foundation 100 through the motor seat 105 , and a plurality of bearing seats 101 for installing the rotating rod 102 are also provided on the foundation 100 along the length direction of the rotating rod 102 .

[0052] At the same time, in order to facilitate intelligent control, the contact sensor A342 and the contact sensor B343 are both connected to the controller, and the controller is connected to the motor 106, the air intake pump, the water intake pump, and the pressure sensor; the air intake pump and the water intake pump are respectively connected to the jet pipe 53 and the water spray pipe 52.

[0053] It can be understood that in a possible implementation manner, since the overall length of the U-shaped groove plate 51 is relatively long, the U-shaped groove plate 51 is prone to bend in the middle during use. Therefore, in order to support the middle part of the U-shaped groove plate 51 and avoid bending, a supporting sub-beam 8 is provided on the upper surface of the solar cell assembly array 1 protruding upward on the supporting structure 2 located between the two supporting main beams 3, and the length direction of the supporting main beam 3 and the supporting sub-beam 8 are the same.

[0055] Specifically, Fig. 9 The movable structure includes a first component and a second component which are formed in cooperation with each other, and the first component includes a vertical plate A71, and a horizontal plate A711 and a base block A715 are respectively arranged at both ends of the vertical plate A71, and a step portion A712 is arranged at the end of the horizontal plate A711 to abut against the end of the U-shaped groove plate 51, and a connecting plug plate 713 is arranged at the end of the horizontal plate A711 to cross the open end of the U-shaped groove plate 51; the second component includes a vertical plate B72, and a horizontal plate B724 and a base block B725 are respectively arranged at both ends of the vertical plate B72. 721, a socket A for connecting the plug plate 713 is provided at the end of the base block B721, a plug block 724 is provided at the end of the cross plate B724, and a socket B for inserting the plug block 724 is provided on the end face of the base block A715; and the cross plate A711 and the base block B721 are both fixed with a movable slider 73 that slides along the rectangular slide groove B81, and then based on the above, the first component and the second component are controlled to be assembled for convenient use, and the normal use of the cleaning mechanism is not affected after assembly.

[0056] Specifically, Fig. 9 The base block A715 is also provided with a locking bolt A716 for fixing the insert block 724. The vertical plate A71 and the vertical plate B72 are respectively threaded with a locking bolt B714 and a locking bolt C723 whose ends abut against the two sides of the U-shaped groove plate 51.
