Description

Technical Field

[0001] The present application belongs to the technical field of photovoltaic panel cleaning, and in particular, relates to a photovoltaic panel cleaning device. Background Art

[0002] With the continuous development of photovoltaic technology, there are more and more photovoltaic power stations. The power generation of photovoltaic power stations is affected by many factors. In addition to the photovoltaic power station's own photoelectric conversion efficiency, the impact of the external environment on the photovoltaic power station is also particularly important. The dust in the external environment blocks the photovoltaic panels and has a great impact on the power generation of photovoltaic power stations. Therefore, photovoltaic panel cleaning equipment came into being.

[0003] Most existing photovoltaic panel cleaning equipment uses a water-gas combination method to clean the dust on the surface of the photovoltaic panel. The dust on the surface of the photovoltaic panel is cleaned by high-pressure gas and / or high-pressure water to reduce the phenomenon that the dust in the external environment blocks the photovoltaic panel and causes the power generation of the photovoltaic power station to decrease. However, cleaning the photovoltaic panel by a water-gas combination method cannot effectively clean the floating dust on the photovoltaic panel caused by electrostatic adsorption of floating dust, nor can it solve the adsorption effect of static electricity on the photovoltaic panel on floating dust in the environment after cleaning. Moreover, when cleaning the photovoltaic panel by a water-gas combination method, the photovoltaic panel cleaning equipment needs to be equipped with a water tank and a gas tank at the same time, resulting in a large load and volume of the photovoltaic panel cleaning equipment, which is likely to affect the endurance and flexibility of the photovoltaic panel cleaning equipment.

[0038] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] See also Figure 1 , Figure 1 It is a front view of a photovoltaic panel cleaning device provided in one embodiment of the present application.

[0040] The embodiment of the present application provides a photovoltaic panel cleaning device 100, which includes a drone 10, a hanging component 20, a gas cylinder 30, an ion generator 40, an ion nozzle 50 and a controller (not shown). The hanging component 20 is detachably mounted on the drone 10, and the hanging component 20 is located below the drone 10. The hanging component 20 includes a mounting frame 21 and a joint module 22, and the mounting frame 21 is mounted on the drone 10, and the joint module 22 is connected to the mounting frame 21. The gas cylinder 30 is detachably mounted on the mounting frame 21 of the hanging component 20, and the gas cylinder 30 is used to eject gas. The ion generator 40 is connected to the gas outlet of the gas cylinder 30, and the ion generator 40 is used to generate positive ions or negative ions according to the type of floating dust on the photovoltaic panel, and the ions generated by the ion generator 40 can be ejected from the ion outlet with the gas ejected from the gas cylinder 30. When the photovoltaic panel is positively charged floating dust, the ion generator 40 is used to generate negative ions to neutralize the positively charged floating dust on the photovoltaic panel. When the photovoltaic panel is negatively charged dust, the ion generator 40 is used to generate positive ions to neutralize the negatively charged dust on the photovoltaic panel. The ion nozzle 50 is installed on the joint module 22 of the lower hanging component 20, and the ion nozzle 50 is connected to the ion outlet of the ion generator 40. The ion nozzle 50 is used to spray the gas ejected from the gas cylinder 30 and the ions generated by the ion generator 40 onto the photovoltaic panel together to clean the charged dust gathered on the photovoltaic panel. The controller is used to control the movement of the joint module 22 of the lower hanging component 20 according to the installation angle of the photovoltaic panel, so that the ion nozzle 50 installed on the lower hanging component 20 is adapted to the inclination angle of the photovoltaic panel installation. The controller is also used to control the flow rate of the gas ejected from the gas cylinder 30 according to the charge amount of the dust gathered on the photovoltaic panel, so that the gas and ions ejected from the ion nozzle 50 can completely neutralize the charged dust on the photovoltaic panel, so as to thoroughly clean the dust gathered on the photovoltaic panel.

[0041] The photovoltaic panel cleaning device 100 provided in the present application, in the first aspect, the drone 10 drives the lower hanging component 20 to move, so that the gas cylinder 30, the ion generator 40 and the ion wind nozzle 50 installed on the lower hanging component 20 can move to the position where the photovoltaic panel is located, so that the gas and ions ejected by the ion wind nozzle 50 can clean the photovoltaic panel. A photovoltaic panel cleaning device 100 can clean photovoltaic panels at different positions, without installing a cleaning device on each photovoltaic panel, which is conducive to reducing the cleaning cost of the photovoltaic panel. In the second aspect, the ion wind nozzle 50 can be connected by the gas cylinder 30, the ion generator 40 and the ion wind nozzle 50, and the ion wind nozzle 50 can spray the gas ejected by the gas cylinder 30 and the positive ions or negative ions generated by the ion generator 40 onto the photovoltaic panel. When the floating dust on the photovoltaic panel is caused by electrostatic adsorption of floating dust, the ion generator 40 can generate positive ions or negative ions according to the type of floating dust on the photovoltaic panel, so as to achieve the effect of neutralizing the static electricity of the photovoltaic panel and the floating dust on the photovoltaic panel, thereby reducing the adhesion of the floating dust on the photovoltaic panel. At the same time, the gas ejected from the gas cylinder 30 acts on the floating dust on the photovoltaic panel, which can more efficiently and thoroughly clean the floating dust accumulation caused by electrostatic adsorption of floating dust on the photovoltaic panel, which is beneficial to improving the photoelectric conversion efficiency of the photovoltaic panel. Moreover, since the static electricity on the photovoltaic panel is also neutralized by the ions generated by the ion generator 40, the adsorption force of the cleaned photovoltaic panel on the floating dust in the environment can be reduced, which is beneficial to delay the progress of floating dust accumulation and occlusion after the photovoltaic panel is cleaned, thereby ensuring the photoelectric conversion efficiency of the photovoltaic panel for a period of time after cleaning. Thirdly, since the photovoltaic panel cleaning device 100 is sprayed onto the photovoltaic panel by the gas ejected from the gas cylinder 30 and the positive ions or negative ions generated by the ion generator 40, there is no need to configure a water tank or other structure to hold the cleaning liquid, which can reduce the load and volume of the photovoltaic panel cleaning device 100, which is beneficial to improving the endurance and movement flexibility of the photovoltaic panel cleaning device 100. Fourthly, the controller controls the joint module 22 to drive the ion nozzle 50 to move according to the installation angle of the photovoltaic panel, so that the spray angle of the ion nozzle 50 is adapted to the tilt angle of the photovoltaic panel, which can make the photovoltaic panel cleaning device 100 more intelligent, and improve the cleaning quality and cleaning efficiency of the photovoltaic panel by the ions and gas ejected by the ion nozzle 50. The controller controls the flow rate of the gas ejected from the gas cylinder 30 according to the amount of charge carried by the floating dust on the photovoltaic panel, so that the ions ejected from the ion nozzle 50 can completely neutralize the static electricity on the photovoltaic panel, thereby making the photovoltaic panel cleaning device 100 clean the photovoltaic panel more thoroughly and efficiently.

[0042] See also Figure 1 and Figure 2 , Figure 2 It is a partial assembly of a photovoltaic panel cleaning device provided in an embodiment of the present application Figure 1 .

[0043] In the photovoltaic panel cleaning device 100 provided in this embodiment, the ion generator 40 is connected and fixed to the gas outlet pipe 31 of the gas cylinder 30, and the ion generator 40 is connected to the gas outlet pipe 31 of the gas cylinder 30 to form a structure in which the gas cylinder 30, the ion generator 40 and the ion air nozzle 50 are connected in sequence. Among them, the gas cylinder 30, the ion generator 40 and the ion air nozzle 50 are connected in sequence through a deformable pipe (not shown in the figure). As a result, the gas ejected from the gas cylinder 30 through the gas outlet pipe 31 can drive the ions generated by the ion generator 40 to move, and finally the ions and gas are ejected together through the ion air nozzle 50 and act on the photovoltaic panel. It can be understood that in some other embodiments, the gas cylinder 30 and the ion generator 40 are both fixedly mounted on the mounting frame 21 of the lower hanging component 20, and the air outlet pipe 31 of the gas cylinder 30 and the ion generator 40 are respectively connected to the ion wind nozzle 50, that is, the gas ejected from the air outlet pipe 31 of the gas cylinder 30 is directly ejected through the ion wind nozzle 50, and the ions generated by the ion generator 40 flow into the ion wind nozzle 50 and are ejected from the ion wind nozzle 50 together with the gas generated by the gas cylinder 30. The present application does not impose any restrictions on this.

[0044] See also Figure 1 and Figure 2 In the photovoltaic panel cleaning device 100 provided in this embodiment, a gas cylinder 30 is provided with a gas outlet valve 32, and the controller controls the flow rate of the gas ejected from the gas cylinder 30 by controlling the opening and closing degree of the gas outlet valve 32, thereby controlling the number of ions contained in the gas ejected from the ion air nozzle 50. When the controller controls the gas outlet valve 32 of the gas cylinder 30 to be opened more, the flow rate of the gas ejected from the gas cylinder 30 is larger, thereby driving more ions to be ejected from the ion air nozzle 50. When the controller controls the gas outlet valve 32 of the gas cylinder 30 to be opened less, the flow rate of the gas ejected from the gas cylinder 30 is smaller, thereby driving fewer ions to be ejected from the ion air nozzle 50. In this way, the controller can control the gas flow rate ejected from the gas cylinder 30 and the number of ions ejected from the ion air nozzle 50.

[0045] See also Figure 1 The photovoltaic panel cleaning device 100 provided in this embodiment cleans the photovoltaic panel, and at least includes the following steps:

[0046] Step 1: The drone 10 drives the photovoltaic panel cleaning device 100 to fly from the base to the air above the photovoltaic panel. The drone 10 drives the photovoltaic panel cleaning device 100 to fly from the base to the air above the photovoltaic panel. The drone 10 can cooperate with the photovoltaic panel cleaning device 100 by cruising, and the operator can remotely control the drone 10 to drive the photovoltaic panel cleaning device 100 to accurately fly from the base to the air above the photovoltaic panel.

[0047] Step 2: The controller controls the joint module 22 of the lower hanging assembly 20 to move according to the tilt angle of the photovoltaic panel, so that the spray angle of the ion air nozzle 50 is adapted to the tilt angle of the photovoltaic panel. The controller controls the joint module 22 to rotate, so that the spray angle of the ion air nozzle 50 is adapted to the tilt angle of the photovoltaic panel.

[0048] Step 3: The controller controls the gas flow rate of the gas cylinder 30 according to the charge of the floating dust on the photovoltaic panel, so as to further control the number of ions ejected from the ion nozzle 50, so that the number of ions ejected from the ion nozzle 50 can completely neutralize the charge of the floating dust on the photovoltaic panel. The controller controls the flow rate of the gas ejected from the gas cylinder 30 by controlling the opening and closing degree of the gas outlet valve 32 of the gas cylinder 30.

[0049] Step 4: The drone 10 drives the photovoltaic panel cleaning device 100 to move relative to the photovoltaic panel, and ensures that the distance between the ion nozzle 50 and the photovoltaic panel is always constant, and ensures that the spray angle of the ion nozzle 50 is always adapted to the tilt angle of the photovoltaic panel. The drone 10 can drive the photovoltaic panel cleaning device 100 to move relative to the photovoltaic panel along the length direction or width direction of the photovoltaic panel.

[0050] Step 5: The drone 10 drives the photovoltaic panel cleaning device 100 to fly from the photovoltaic panel to the return base.

The cruise drone 10 can cooperate with the photovoltaic panel cleaning device 100, and the operator can remotely control the drone 10 to drive the photovoltaic panel cleaning device 100 to accurately fly from the base to the sky above the photovoltaic panel. Moreover, when the photovoltaic panels of multiple different base stations need to be cleaned, after the fourth step, the drone 10 can drive the photovoltaic panel cleaning device 100 to fly from one base station to another.

[0051] See also Figure 1 and Figure 3 , Figure 3 This is an assembly diagram of a lower hanging component provided in one embodiment of the present application.

[0052] In one embodiment, the photovoltaic panel cleaning device 100 also includes a sensor, which is used to sense the inclination angle of the ion nozzle 50 relative to the photovoltaic panel and form a first sensing information, and is used to sense the amount of charge on the photovoltaic panel and form a second sensing information. The controller controls the movement of the joint module 22 according to the first sensing information so that the spray angle of the ion nozzle 50 adapts to the inclination angle of the photovoltaic panel. The controller is also used to control the flow rate of the gas sprayed from the gas cylinder 30 according to the second sensing information. It should be understood that in the photovoltaic panel cleaning device 100 provided in this embodiment, the sensor can be installed on the mounting frame 21 of the lower hanging component 20, or it can be installed on the surrounding side of the ion nozzle 50, and this application does not limit this.

[0053] The photovoltaic panel cleaning device 100 provided in this embodiment obtains the first sensing information and the second sensing information through the sensor, so that the first sensing information and the second sensing information are more accurate, so that the controller can more accurately control the movement of the joint module 22 and the flow rate of the gas sprayed from the gas cylinder 30, so that the spray angle of the ion wind nozzle 50 and the tilt angle of the photovoltaic panel can be better adapted, and the flow rate of the gas sprayed from the gas cylinder 30 can thoroughly clean the floating dust accumulated on the photovoltaic panel, and can also neutralize the number of ions sprayed with the gas cylinder 30 and the charge on the photovoltaic panel. Therefore, under the premise of saving the gas consumption of the gas cylinder 30, obtaining the first sensing information and the second sensing information through the sensor is conducive to improving the cleaning quality of the photovoltaic panel by the photovoltaic panel cleaning device 100, and then improving the photoelectric conversion efficiency of the photovoltaic panel.

[0054] See also Figure 1 In the photovoltaic panel cleaning device 100 provided in this embodiment, the controller is installed on the mounting frame 21 of the lower hanging component 20, and the controller can be directly electrically connected to the sensor to obtain the signal sent by the sensor. It can be understood that in some other embodiments, the controller can be a remote control structure configured by the operator, and the operator processes the signal sent by the sensor and makes the controller remotely control the photovoltaic panel cleaning device 100, and this application does not limit this.

[0055] See also Figures 1 to 3 The photovoltaic panel cleaning device 100 provided in this embodiment includes a position sensor (not shown) and a charge sensor (not shown). The position sensor is at least used to obtain the tilt angle of the photovoltaic panel and the spray angle of the ion wind nozzle 50 to form the first sensing information. The controller controls the movement of the joint module 22 according to the first sensing information to adjust the spray angle of the ion wind nozzle 50 to match the tilt angle of the photovoltaic panel. The charge sensor is at least used to obtain the amount of charge after the floating dust gathers on the photovoltaic panel to form the second sensing information. The controller controls the opening and closing degree of the outlet valve 32 of the gas cylinder 30 according to the second sensing information, so that the number of ions sprayed by the ion wind nozzle 50 can completely neutralize the charge after the floating dust gathers on the photovoltaic panel.

[0056] It can be understood that in some other embodiments, the sensor also includes an image sensor, which is at least used to obtain the degree of dust accumulation on the photovoltaic panel to form third sensing information. The controller can control the opening and closing degree of the outlet valve 32 of the gas cylinder 30 based on the third sensing information, so that the gas sprayed from the ion wind nozzle 50 can completely blow away the dust accumulated on the photovoltaic panel. The present application does not impose any restrictions on this.

Taking the photovoltaic panel as a rectangular plate structure as an example, the controller controls the joint module 22 to adjust the position of the connecting rod 23 relative to the photovoltaic panel, including the joint module 22 adjusting the rotation of the connecting rod 23 relative to the joint module 22, so that the connecting rod 23 is parallel to one side of the photovoltaic panel.

The number of the ion air nozzles 50 of the photovoltaic panel cleaning device 100 is multiple, and the multiple ion air nozzles 50 are arranged in sequence from the first end 231 to the second end 232 of the connecting rod 23. The photovoltaic panel cleaning device 100 also includes multiple adjustment components 60, each of which is connected between an ion air nozzle 50 and the connecting rod 23, and the adjustment component 60 is used to adjust the position of the ion air nozzle 50 relative to the photovoltaic panel so that the spray direction of each ion air nozzle 50 is perpendicular to the photovoltaic panel. After the controller controls the joint machine module to adjust the connecting rod 23 to a state parallel to the photovoltaic panel, the controller controls each adjustment component 60 to adjust the position of the ion air nozzle 50 connected thereto relative to the photovoltaic panel so that the spray direction of each ion air nozzle 50 is perpendicular to the photovoltaic panel.

[0059] The photovoltaic panel cleaning device 100 provided in this embodiment, in the first aspect, controls the joint module 22 through the controller to adjust the connecting rod 23 so that the connecting rod 23 is arranged parallel to the photovoltaic panel. Moreover, a plurality of spaced ion nozzles 50 are arranged on the connecting rod 23 in the direction from the first end 231 to the second end 232 of the connecting rod 23. Thus, when the drone 10 drives the connecting rod 23 to move in a direction parallel to the photovoltaic panel and perpendicular to the connecting rod 23, the plurality of ion nozzles 50 can spray gas and ions to clean the entire surface of the photovoltaic panel, which is beneficial to improving the cleaning efficiency of the photovoltaic panel cleaning device 100 for the photovoltaic panel. In the second aspect, an adjustment component 60 is connected to the connecting rod 23 and an ion nozzle 50, and under the action of the adjustment component 60, the spray direction of each ion nozzle 50 is perpendicular to the photovoltaic panel. Thus, it is beneficial to improve the cleaning quality of the photovoltaic panel by the ion nozzle 50 spraying gas and ions, reduce the residual floating dust on the photovoltaic panel, and thus improve the photoelectric conversion efficiency of the photovoltaic panel.

[0060] See also Figure 1 It can be understood that in some other embodiments, in order to prevent the gas and ions ejected from the ion wind nozzle 50 from blowing floating dust to the cleaned area of ​​the photovoltaic panel, the ejection direction of the ion wind nozzle 50 and the flight direction of the drone 10 are at an obtuse angle, that is, the ejection direction of the ion wind nozzle 50 is inclined relative to the photovoltaic panel, and the present application does not impose any restrictions on this.

[0061] See also Figures 1 to 5 , Figure 5 yes Figure 4 An enlarged schematic diagram of the photovoltaic panel cleaning equipment at point A is shown.

[0062] In one embodiment, the adjustment component 60 of the photovoltaic panel cleaning device 100 includes a connecting member 61 and a first movable member 62, wherein the connecting member 61 is fixedly connected to the connecting rod 23, the first movable member 62 is rotatably connected to the connecting member 61 around the first axis L1, and the ion air nozzle 50 is fixedly connected to the first movable member 62. The first axis L1 is parallel to the direction from the first end 231 to the second end 232 of the connecting rod 23. After the controller controls the joint machine module to adjust the connecting rod 23 to a state parallel to the photovoltaic panel, the controller can further control the first movable member 62 to rotate relative to the connecting member 61 around the first axis L1, thereby adjusting the inclination angle of the spray direction of the ion air nozzle 50 relative to the photovoltaic panel.

[0063] The photovoltaic panel cleaning device 100 provided in this embodiment can rotate around the first axis L1 relative to the connecting member 61 through the first movable part 62 of the adjustment component 60, so that the adjustment component 60 can adjust the spray direction of the ion nozzle 50, and then the ion nozzle 50 can adapt to different inclination directions of the photovoltaic panels, which is beneficial to improving the cleaning effect of the gas and ions sprayed by the ion nozzle 50 on the photovoltaic panels, and improving the compatibility of the photovoltaic panel cleaning device 100 for cleaning photovoltaic panels with different inclination angles.

[0064] See also Figures 1 to 6 , Figure 6 It is an assembly diagram of an ion air nozzle and an adjustment component provided in one embodiment of the present application.

[0065] In a specific embodiment, the connecting member 61 of the adjustment component 60 is provided with an annular groove 611 extending circumferentially around the first axis L1, and the annular groove 611 penetrates the connecting member 61 along the direction of the first axis L1. The first movable member 62 is provided with a fixed portion 621 and a movable portion 622. The fixed portion 621 is rotatably connected to the connecting member 61, and the connection between the fixed portion 621 and the connecting member 61 is located on the first axis L1. The movable portion 622 is penetrated by the annular groove 611 and can move circumferentially around the first axis L1 in the annular groove 611, so that the first movable member 62 can rotate around the first axis L1 relative to the connecting member 61, thereby facilitating the adjustment component 60 to adjust the inclination angle of the ion nozzle 50 relative to the photovoltaic panel. Among them, the fixed portion 621 and the connecting member 61 are detachably connected, and the movable portion 622 is detachably connected to the annular groove 611. At the same time, in order to reduce the overall weight of the adjustment component 60, a weight-reducing hole can be provided on the connecting member 61, and a weight-reducing hole can be provided on the first movable member 62.

[0066] See also Figures 1 to 8 , Figure 7 Schematic diagram of the assembly of the connecting member and the first movable member provided in one embodiment of the present application Figure 1 , Figure 8 Schematic diagram of the assembly of the connecting member and the first movable member provided in one embodiment of the present application Figure 2 .

[0067] In some embodiments, the connecting member 61 and the first movable member 62 at least partially overlap along the first axis L1. In the overlapping portion of the connecting member 61 and the first movable member 62, a first positioning portion 612 is provided on the connecting member 61, and a second positioning portion 623 is provided on the first movable member 62. When the first positioning portion 612 is aligned with the second positioning portion 623, the first movable member 62 is in a zero-point positioning state relative to the connecting member 61. At this time, the movable portion 622 is located in the annular groove 611 and can rotate clockwise or counterclockwise around the first axis L1.

[0068] Specifically, the first positioning portion 612 is a through hole provided on the connecting member 61, and the second positioning portion 623 is a through hole provided on the first movable member 62. When the first positioning portion 612 is aligned with the second positioning portion 623, the first positioning portion 612 and the second positioning portion 623 can be clamped by a clamping member to keep the first movable member 62 in a zero-point positioning state relative to the connecting member 61. At this time, the movable portion 622 is in the middle position of the annular groove 611, that is, the angle of the movable portion 622 rotating clockwise around the first axis L1 in the annular groove 611 is equal to the angle of the movable portion 622 rotating counterclockwise around the first axis L1 in the annular groove 611. In other words, the annular groove 611 includes a first wall surface 6111 and a second wall surface 6112 which are relatively arranged along the circumferential direction of the first axis L1. When the first movable member 62 is in a zero-point positioning state relative to the connecting member 61, in the circumferential direction of the first axis L1, the distance between the movable portion 622 and the first wall surface 6111 of the annular groove 611 is equal to the distance between the movable portion 622 and the second wall surface 6112 of the annular groove 611.

[0069] The first positioning portion 612 is provided on the connecting member 61, and the second positioning portion 623 is provided on the first movable member 62. When the first positioning portion 612 is aligned with the second positioning portion 623, the first movable member 62 is in a zero-point positioning state relative to the connecting member 61. At this time, the movable member 622 is located in the annular groove 611 and can rotate clockwise or counterclockwise around the first axis L1, and the angle of the clockwise rotation of the movable member 622 around the first axis L1 in the annular groove 611 is equal to the angle of the counterclockwise rotation of the movable member 622 around the first axis L1 in the annular groove 611. Therefore, when the photovoltaic panel cleaning device 100 needs to clean photovoltaic panels with different tilt angles, based on the tilt angle of the photovoltaic panel corresponding to the zero-point positioning, it is only necessary to design the clockwise rotation angle of the movable member 622 in the annular groove 611 and the counterclockwise transmission angle of the movable member 622 in the annular groove 611 to make the ion nozzle 50 adapt to photovoltaic panels with different tilt angles. When the movable part 622 is controlled by the controller, it is also convenient to simplify the program algorithm design of the adjustment component 60 for adjusting the rotation angle of the ion nozzle 50, and make the program stability of the adjustment component 60 for adjusting the rotation angle of the ion nozzle 50 better.

[0070] See also Figures 1 to 6In a specific embodiment, the adjustment component 60 also includes a rotating member 63 and a second movable member 64, the housing 631 of the rotating member 63 is fixedly connected to the second movable member 64, the output shaft 632 of the rotating member 63 is connected to the second movable member 64, the rotating member 63 is used to drive the second movable member 64 to rotate around the second axis L2, and the ion wind nozzle 50 is fixedly connected to the second movable member 64. Among them, the rotating member 63 provided in this embodiment is a servo, and the second axis L2 is perpendicular to the direction from the first end 231 to the second end 232 of the connecting rod 23. After the controller controls the joint machine module to adjust the connecting rod 23 to a state parallel to the photovoltaic panel, the controller can further control the rotating member 63 to drive the second movable member 64 to rotate around the first axis L1, so as to adjust the inclination angle of the injection direction of the ion wind nozzle 50 relative to the photovoltaic panel.

[0071] The photovoltaic panel cleaning device 100 provided in this embodiment, on the one hand, can rotate around the second axis L2 through the second movable member 64 of the adjustment component 60, so that the adjustment component 60 can further and more accurately adjust the spray direction of the ion wind nozzle 50, and then the ion wind nozzle 50 can adapt to the different tilt directions of the photovoltaic panel, which is beneficial to improve the cleaning effect of the gas and ions sprayed by the ion wind nozzle 50 on the photovoltaic panel, and improve the compatibility of the photovoltaic panel cleaning device 100 for cleaning photovoltaic panels with different tilt angles. On the other hand, in the process of the photovoltaic panel cleaning device 100 cleaning the photovoltaic panel, the rotating member 63 can drive the ion wind nozzle 50 to rotate around the second axis L2 to adjust the spray direction of the gas and ions sprayed by the ion wind nozzle 50, so that the area between two adjacent ion wind nozzles 50 can also be cleaned by gas and ions, which is beneficial to improve the cleaning quality of the photovoltaic panel by the photovoltaic panel cleaning device 100.

[0072] See also Figures 1 to 8 In some embodiments, at least parts of the first movable member 62 and the second movable member 64 overlap along the second axis L2, a third positioning portion (not shown) is provided on the first movable member 62, and a fourth positioning portion (not shown) is provided on the second movable member. When the first positioning portion 612 is aligned with the second positioning portion 623, the injection direction of the ion nozzle 50 installed on the second movable member 64 is perpendicular to the extension direction of the connecting rod 23. At this time, the rotating member 63 can drive the second movable member 64 to rotate clockwise or counterclockwise around the second axis L2.

[0073] In a specific embodiment, the third positioning portion is a through hole provided on the first movable member 62, and the fourth positioning portion is a through hole provided on the second movable member 64. When the first positioning portion 612 is aligned with the second positioning portion 623, the third positioning portion and the fourth positioning portion can be clamped by a clamping member to keep the second movable member 64 in a relatively fixed state relative to the first movable member 62. At this time, the spraying direction of the ion wind nozzle 50 is perpendicular to the photovoltaic panel, and the angle at which the rotating member 63 drives the second movable member 64 and the ion wind nozzle 50 to rotate clockwise around the second axis L2 is equal to the angle at which the rotating member 63 drives the second movable member 64 to rotate counterclockwise around the second axis L2. The design principles of the third positioning portion and the fourth positioning portion are the same as those of the first positioning portion 612 and the second positioning portion 623, and will not be elaborated here. The designer can flexibly design the third positioning portion and the fourth positioning portion according to the design principles of the first positioning portion 612 and the second positioning portion 623.

[0074] It should be understood that since there is a certain spacing distance between the ion wind nozzle 50 and the photovoltaic panel, in order to prevent the rotating member 63 from driving the second movable member 64 and the ion wind nozzle 50 to rotate at too large an angle, resulting in the spraying direction of the ion wind nozzle 50 being parallel to the photovoltaic panel and unable to clean the floating dust on the photovoltaic panel, a limit portion (not shown) can be provided on the first movable member 62. The limit portion is used to limit the rotation angle of the second movable member 64 around the second axis L2, thereby ensuring that the angle between the spraying direction of the ion wind nozzle 50 and the photovoltaic panel is not equal to 0.

[0075] The photovoltaic panel cleaning device 100 provided in this embodiment has a third positioning portion provided on the first movable member 62 and a fourth positioning portion provided on the second movable member 64. When the first positioning portion 612 is aligned with the second positioning portion 623, the spray direction of the ion nozzle 50 installed on the second movable member 64 is perpendicular to the extension direction of the connecting rod 23. At this time, the rotating member 63 can drive the second movable member 64 to rotate clockwise or counterclockwise around the second axis L2. Therefore, when the ion nozzle 50 of the photovoltaic panel cleaning device 100 needs to clean the photovoltaic panel at different tilt angles, based on the tilt angle of the photovoltaic panel corresponding to the spray angle of the ion nozzle 50 when the third positioning portion is aligned with the fourth positioning portion, it is only necessary to design the clockwise rotation angle of the rotating member 63 driving the second movable member 64 around the second axis L2 and the counterclockwise transmission angle of the rotating member 63 driving the second movable member 64 around the second axis L2, so that the ion nozzle 50 can clean the photovoltaic panel at different tilt angles. When the rotating member 63 is controlled by the controller, it is also convenient to simplify the program algorithm design of the adjustment component 60 for adjusting the rotation angle of the ion nozzle 50, and make the program stability of the adjustment component 60 for adjusting the rotation angle of the ion nozzle 50 better.

[0076] See also Figures 1 to 9 , Fig. 9It is a structural diagram of a first movable part provided in one embodiment of the present application.

[0077] In a specific embodiment, the first movable member 62 has a first receiving chamber 624, and the first receiving chamber 624 is in a "C" shape. The shell 631 of the rotating member 63 is received in the first receiving chamber 624. The first receiving chamber 624 of the first movable member 62 is in a "C" shape, so that the shell 631 of the rotating member 63 can be received and fixed in the first receiving chamber 624. When the first movable member 62 rotates around the first axis L1 relative to the connecting member 61, it can drive the rotating member 63 to rotate around the first axis L1, and then drive the ion wind nozzle 50 to rotate around the first axis L1 relative to the connecting member 61. In addition, the second movable member 64 has a second receiving chamber 641, and the second receiving chamber 641 is in a "C" shape. The second receiving chamber 641 includes a first inner side wall and a second inner side wall that are relatively arranged along the second axis L2. The output shaft 632 of the rotating member 63 is arranged along the second axis L2, one end of the output shaft 632 of the rotating member 63 is fixedly connected to the first inner wall, and the other end of the output shaft 632 of the rotating member 63 is fixedly connected to the second inner wall, so that the rotating member 63 drives the second movable member 64 to rotate around the second axis L2.

[0078] The photovoltaic panel cleaning device 100 provided in this embodiment is "C"-shaped through the second receiving cavity 641 of the second movable part 64, so that the output shaft 632 of the rotating part 63 can be accommodated in the second receiving cavity 641, and the opposite ends of the output shaft 632 of the rotating part 63 are respectively and fixedly connected to the first inner side wall and the second inner side wall, so that the second movable part 64 can drive the ion nozzle 50 to rotate around the second axis L2 when rotating around the second axis L2, and thus the injection direction of the ion nozzle 50 can be adjusted to a direction perpendicular to the photovoltaic panel.

[0079] It is understandable that in some other embodiments, the first receiving cavity 624 may be in a “mouth” shape so that the housing 631 of the rotating member 63 is fixed in the first receiving cavity 624 with better stability, and the present application does not impose any limitation on this.

[0080] See also Figures 1 to 6In a specific embodiment, the size of the first movable member 62 along the second axis L2 is smaller than the size of the second receiving cavity 641 along the second axis L2. When the rotating member 63 drives the second movable member 64 to rotate around the second axis L2, the rotation interference between the first movable member 62 and the second movable member 64 can be avoided, which leads to the rotation angle of the second movable member 64 being limited. As a result, the second movable member 64 can rotate around the second axis L2 at a larger angle, so that the rotating member 63 can drive the ion nozzle 50 to rotate around the second axis L2 at a larger angle. The ion nozzle 50 can adapt to more photovoltaic panels with different tilt angle designs, which is conducive to improving the cleaning compatibility of the photovoltaic panel cleaning device 100 for photovoltaic panels with different tilt angle designs. At the same time, the rotating member 63 can drive the ion nozzle 50 to rotate around the second axis L2 at a larger angle, which can make the spray angle range of the ion nozzle 50 larger. The gas and ions ejected by the ion nozzle 50 can completely cover the area between the two adjacent ion nozzles 50 corresponding to the photovoltaic panel, which is conducive to improving the cleaning quality of the photovoltaic panel cleaning device 100 for the photovoltaic panel.

[0081] See also Figures 1 to 6 In a specific embodiment, along the direction of the second axis L2, a part of the ion air nozzle 50 is stacked and fixedly connected with the second movable part 64, and another part of the ion air nozzle 50 is suspended. Moreover, the part of the ion air nozzle 50 fixedly connected to the second movable part 64 is spaced apart from the connecting member 61. As a result, when the ion air nozzle 50 rotates around the second axis L2 under the action of the rotating member 63, the rotational interference between the ion air nozzle 50 and the connecting member 61 can be avoided, which leads to the limitation of the rotation angle of the ion air nozzle 50. The rotation angle of the ion air nozzle 50 around the second axis L2 can be larger, so that the ion air nozzle 50 can adapt to more photovoltaic panels designed with different inclination angles, which is beneficial to improve the cleaning compatibility of the photovoltaic panel cleaning equipment 100 for photovoltaic panels designed with different inclination angles.

[0082] See also Figures 1 to 10 , Fig.10 It is a structural diagram of a second movable part provided in one embodiment of the present application.

The second part 643 is in the shape of a plate, the second part 643 is coplanar with the first plate 6421, the second part 643 is spaced apart from the first part 642, and another part of the ion nozzle 50 is fixed to one side of the second part 643. The third part 644 is in a plate shape, one side of the third part 644 is fixedly connected to the outer side wall of the second plate 6422, and the other side of the third part 644 is fixedly connected to the side of the second part 643 away from the ion nozzle 50. It can be understood that in some other embodiments, the first part 642, the second part 643 and the third part 644 of the second movable member 64 can be an integrated structure, and the present application does not limit this.

[0084] The photovoltaic panel cleaning device 100 provided in this embodiment is arranged coplanarly with the first plate 6421 of the second part 643 and the third part 644, so that the ion nozzle 50 can be installed on the first part 642 and the second part 643. At the same time, the second part 643 is suspended relative to the first part 642, one side of the third part 644 is fixedly connected to the outer side wall of the second plate 6422 of the first part 642, and the other side of the third part 644 is fixedly connected to the side of the second part 643 away from the ion nozzle 50, so that the third part 644 forms a support for the second part 643, which is conducive to improving the stability of the ion nozzle 50 installed on the second part 643.
