Description

Technical Field

[0001] This application belongs to the field of photovoltaic panel cleaning technology, and in particular relates to a photovoltaic panel cleaning device. Background Technology

[0002] With the continuous development of photovoltaic technology, photovoltaic power plants are becoming increasingly common. The power generation of photovoltaic power plants is affected by many factors. Besides the photovoltaic conversion efficiency of the power plant itself, the impact of the external environment is also significant. Dust in the external environment that obstructs the photovoltaic panels has a substantial impact on the power generation of photovoltaic power plants. Therefore, photovoltaic panel cleaning equipment has emerged.

[0003] Existing photovoltaic (PV) panel cleaning equipment primarily uses a combination of water and air to clean dust from the PV panel surface. This involves using high-pressure gas and / or high-pressure water to remove dust and reduce the shading effect of external dust, which can lead to a decrease in PV power generation. However, this water-air method is ineffective at removing dust caused by electrostatic adsorption, and it also fails to address the issue of static electricity on the PV panels attracting dust from the environment after cleaning. Furthermore, this method requires both a water tank and an air tank, resulting in a large load and size, which can negatively impact the equipment's endurance and flexibility. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a photovoltaic panel cleaning device that can improve the cleaning quality and efficiency of cleaning photovoltaic panels that are blocked by floating dust due to electrostatic adsorption, and can also reduce the adsorption effect of static electricity on floating dust in the environment after cleaning.

[0005] This application provides a photovoltaic panel cleaning device, comprising:

[0006] Drones;

[0007] The undermount assembly includes a mounting frame and a joint module, wherein the mounting frame is mounted on the drone and the joint module is connected to the mounting frame;

[0010] An ion nozzle, installed on the joint module, connects to the gas cylinder, the ion generator, and the ion nozzle. The ion nozzle is used to spray the gas ejected from the gas cylinder and the ions generated by the ion generator onto the photovoltaic panel.

[0011] The controller is used to control the movement of the joint module so that the spray angle of the ion nozzle is adapted to the tilt angle of the photovoltaic panel, and to control the flow rate of the gas ejected from the gas cylinder according to the charge of the dust floating on the photovoltaic panel.

[0012] In one possible implementation, the photovoltaic panel cleaning equipment further includes a sensor for sensing the tilt angle of the ion nozzle relative to the photovoltaic panel and generating first sensing information, and for sensing the amount of charge on the photovoltaic panel and generating second sensing information; the controller controls the movement of the joint module according to the first sensing information so that the spray angle of the ion nozzle is adapted to the tilt angle of the photovoltaic panel; the controller controls the flow rate of the gas ejected from the gas cylinder according to the second sensing information.

[0013] In one possible implementation, the hanging assembly further includes a connecting rod, which has a first end and a second end disposed opposite to each other. The joint module is connected at the midpoint between the first end and the second end. The joint module is used to adjust the position of the connecting rod relative to the photovoltaic panel so that the connecting rod is parallel to the photovoltaic panel. The ion nozzles are multiple in number and are arranged at intervals along the first end to the second end. The photovoltaic panel cleaning equipment further includes multiple adjusting components, each of which connects one ion nozzle to the connecting rod. The adjusting components are used to adjust the position of the ion nozzle relative to the photovoltaic panel so that the spray direction of each ion nozzle is perpendicular to the photovoltaic panel.

[0014] In one possible implementation, the adjustment assembly includes a connector and a first movable member; the connector is fixedly connected to the connecting rod, the first movable member is rotatably connected to the connector about a first axis, and the ion nozzle is fixedly connected to the first movable member; wherein, the first axis is parallel to the direction from the first end to the second end of the connecting rod.

[0015] In one possible implementation, the connector is provided with an annular groove extending circumferentially around the first axis; the first movable member is provided with a fixed part and a movable part; the fixed part is rotatably connected to the connector, and the connection between the fixed part and the connector is located on the first axis; the movable part passes through the annular groove and is capable of circumferential movement around the first axis within the annular groove, so that the first movable member can rotate relative to the connector around the first axis.

[0016] In one possible implementation, the adjustment assembly further includes a rotating member and a second movable member; the housing of the rotating member is fixedly connected to the second movable member, the output shaft of the rotating member is connected to the second movable member, the rotating member is used to drive the second movable member to rotate around a second axis, and the ion nozzle is fixedly connected to the second movable member; wherein, the second axis is perpendicular to the direction from the first end to the second end of the connecting rod.

[0017] In one possible implementation, the first movable member has a first receiving cavity, which is C-shaped, and the housing of the rotating member is housed in the first receiving cavity; the second movable member has a second receiving cavity, which is C-shaped, and includes a first inner sidewall and a second inner sidewall disposed opposite to each other along the second axis; the output shaft of the rotating member is disposed along the second axis, one end of the output shaft of the rotating member is fixedly connected to the first inner sidewall, and the other end of the output shaft of the rotating member is fixedly connected to the second inner sidewall, so that the rotating member drives the second movable member to rotate around the second axis.

[0018] In one possible implementation, the dimension of the first movable member along the second axis is smaller than the dimension of the second receiving cavity along the second axis.

[0019] In one possible implementation, along the direction of the second axis, a portion of the ion nozzles are stacked and fixedly connected to the second movable component, while another portion of the ion nozzles are suspended in the air.

[0020] In one possible implementation, the second movable member includes a first part, a second part, and a third part; the first part includes a first plate, a second plate, and a third plate connected in sequence, the first plate and the third plate being arranged opposite each other along the second axis, the first plate, the second plate, and the third plate forming the second receiving cavity, and a portion of the ion nozzle being fixed to the outer side wall of the first plate; the second part is plate-shaped, the second part being coplanar with the first plate and spaced apart, and another portion of the ion nozzle being fixed to one side of the second part; the third part is plate-shaped, one side of the third part being fixedly connected to the second plate, and the other side of the third part being fixedly connected to the side of the second part opposite to the ion nozzle.

[0021] The photovoltaic panel cleaning equipment provided in this application has two main aspects. First, by using a drone to move the lower-mounted modules, the gas cylinders, ion generators, and ion nozzles installed on the modules can be moved to the location of the photovoltaic panels. This facilitates the cleaning of the photovoltaic panels by the gas and ions sprayed from the ion nozzles. One photovoltaic panel cleaning device can clean photovoltaic panels at different locations, eliminating the need to install a separate cleaning device on each photovoltaic panel, thus reducing cleaning costs. Second, by connecting the gas cylinders, ion generators, and ion nozzles, the ion nozzles can spray the gas from the gas cylinders and the positive or negative ions generated by the ion generator onto the photovoltaic panels. When dust accumulates on the photovoltaic panels due to electrostatic adsorption, the ion generator can generate positive or negative ions according to the type of dust on the photovoltaic panels, neutralizing the static electricity of the photovoltaic panels and the dust, thereby reducing the adhesion of the dust to the photovoltaic panels. Simultaneously, the gas sprayed from the gas cylinders acts on the dust on the photovoltaic panels, cleaning the dust accumulation caused by electrostatic adsorption more efficiently and thoroughly, which helps to improve the photoelectric conversion efficiency of the photovoltaic panels. Furthermore, since the static electricity on the photovoltaic panel is neutralized by ions generated by the ion generator, the adsorption of dust from the environment by the cleaned photovoltaic panel can be reduced. This helps to delay the re-accumulation of dust and the formation of shading after cleaning, thus ensuring the photovoltaic conversion efficiency of the photovoltaic panel for a period of time after cleaning. Thirdly, because the photovoltaic panel cleaning equipment sprays gas from a gas cylinder and positive or negative ions generated by the ion generator onto the photovoltaic panel, there is no need for a water tank or other structure to hold the cleaning fluid. This reduces the load and size of the photovoltaic panel cleaning equipment, improving its endurance and operational flexibility. Fourthly, by controlling the joint module to move the ion nozzle according to the installation angle of the photovoltaic panel, the controller adapts the spray angle of the ion nozzle to the tilt angle of the photovoltaic panel. This makes the photovoltaic panel cleaning equipment more intelligent and improves the cleaning quality and efficiency of the ions and gas sprayed from the ion nozzle. The controller adjusts the flow rate of gas ejected from the cylinder based on the charge carried by the dust on the photovoltaic panel, so that the ions ejected from the ion nozzle can completely neutralize the static electricity on the photovoltaic panel, thereby making the photovoltaic panel cleaning equipment more thorough and efficient in cleaning the photovoltaic panel.

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Please see Figure 1 , Figure 1 This is a front view of a photovoltaic panel cleaning device provided in an embodiment of this application.

[0040] This application provides a photovoltaic panel cleaning device 100, which includes a drone 10, an undermount assembly 20, a gas cylinder 30, an ion generator 40, an ion nozzle 50, and a controller (not shown). The undermount assembly 20 is detachably mounted on the drone 10 and is located below the drone 10. The undermount assembly 20 includes a mounting frame 21 and a joint module 22. 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 undermount assembly 20 and is used to spray gas. The ion generator 40 is connected to the gas outlet of the gas cylinder 30 and is used to generate positive or negative ions depending on the type of dust on the photovoltaic panel. The ions generated by the ion generator 40 can be ejected from the ion outlet along with the gas sprayed from the gas cylinder 30. When the dust on the photovoltaic panel is positively charged, the ion generator 40 generates negative ions to neutralize the positively charged dust on the photovoltaic panel. When the dust particles on the photovoltaic panel are negatively charged, the ion generator 40 generates positive ions to neutralize them. An ion nozzle 50 is installed on the joint module 22 of the undermount component 20. The nozzle 50 is connected to the ion outlet of the ion generator 40 and sprays the gas from the gas cylinder 30 and the ions generated by the ion generator 40 onto the photovoltaic panel to clean the charged dust particles accumulated on it. A controller moves the joint module 22 of the undermount component 20 according to the installation angle of the photovoltaic panel, adapting the ion nozzle 50 to the tilt angle of the photovoltaic panel. The controller also controls the flow rate of the gas from the gas cylinder 30 based on the charge of the dust particles accumulated on the photovoltaic panel, ensuring that the gas and ions from the ion nozzle 50 completely neutralize the charged dust particles, thus thoroughly cleaning the accumulated dust.

[0041] The photovoltaic panel cleaning equipment 100 provided in this application, in the first aspect, uses a drone 10 to move the lower-mounted component 20, enabling the gas cylinder 30, ion generator 40, and ion nozzle 50 installed on the lower-mounted component 20 to move to the location of the photovoltaic panel. This facilitates the cleaning of the photovoltaic panel by the gas and ions sprayed from the ion nozzle 50. One photovoltaic panel cleaning equipment 100 can clean photovoltaic panels at different locations, eliminating the need to install a cleaning device on each photovoltaic panel, thus reducing the cleaning cost. In the second aspect, the gas cylinder 30, ion generator 40, and ion nozzle 50 are connected. The ion nozzle 50 can spray the gas sprayed from the gas cylinder 30 and the positive or negative ions generated by the ion generator 40 onto the photovoltaic panel. When dust accumulates on the photovoltaic panel due to electrostatic adsorption, the ion generator 40 can generate positive or negative ions according to the type of dust on the photovoltaic panel, thereby neutralizing the static electricity of the photovoltaic panel and the dust on it, and reducing the adhesion of the dust to the photovoltaic panel. Simultaneously, the gas ejected from cylinder 30 acts on the dust on the photovoltaic panel, more efficiently and thoroughly cleaning the dust accumulation caused by electrostatic adsorption, which helps improve the photovoltaic conversion efficiency of the photovoltaic panel. Furthermore, since the static electricity on the photovoltaic panel is neutralized by ions generated by ion generator 40, the adsorption force of the cleaned photovoltaic panel on environmental dust is reduced, which helps delay the re-accumulation of dust and the formation of shading after cleaning, thus ensuring the photovoltaic conversion efficiency of the photovoltaic panel for a period of time after cleaning. Thirdly, since the photovoltaic panel cleaning equipment 100 sprays gas from cylinder 30 and positive or negative ions generated by ion generator 40 onto the photovoltaic panel, there is no need for a water tank or other structure to hold the cleaning fluid, which reduces the load and volume of the photovoltaic panel cleaning equipment 100, and improves its endurance and maneuverability. Fourthly, by controlling the joint module 22 to move the ion nozzle 50 according to the installation angle of the photovoltaic panel, the controller adapts the spray angle of the ion nozzle 50 to the tilt angle of the photovoltaic panel. This makes the photovoltaic panel cleaning equipment 100 more intelligent and improves the cleaning quality and efficiency of the ions and gas sprayed by the ion nozzle 50 on the photovoltaic panel. The controller also controls the flow rate of the gas sprayed from the gas cylinder 30 according to the charge carried by the dust on the photovoltaic panel, ensuring that the ions sprayed by the ion nozzle 50 completely neutralize the static electricity on the photovoltaic panel, thus making the cleaning of the photovoltaic panel by the photovoltaic panel cleaning equipment 100 more thorough and efficient.

[0042] Please see Figure 1 and Figure 2 , Figure 2 This application provides a partial assembly of a photovoltaic panel cleaning device according to one embodiment. Figure 1 .

[0043] The photovoltaic panel cleaning equipment 100 provided in this embodiment includes an ion generator 40 connected and fixed to the gas outlet pipe 31 of a gas cylinder 30, with the ion generator 40 and the gas outlet pipe 31 communicating to form a structure in which the gas cylinder 30, the ion generator 40, and the ion nozzle 50 are sequentially connected. The gas cylinder 30, the ion generator 40, and the ion nozzle 50 are sequentially connected via a deformable pipe (not shown in the figure). Thus, the gas ejected from the gas cylinder 30 through the gas outlet pipe 31 can drive the movement of ions generated by the ion generator 40, and finally, the ions and gas are ejected together through the ion nozzle 50 and act on the photovoltaic panel. Understandably, in some other embodiments, both the gas cylinder 30 and the ion generator 40 are fixedly mounted on the mounting frame 21 of the lower assembly 20. The gas outlet pipe 31 of the gas cylinder 30 and the ion generator 40 are respectively connected to the ion nozzle 50. That is, the gas ejected from the gas outlet pipe 31 of the gas cylinder 30 is directly ejected through the ion nozzle 50, and the ions generated by the ion generator 40 flow into the ion nozzle 50 and are ejected from the ion nozzle 50 together with the gas generated by the gas cylinder 30. This application does not limit this.

[0044] Please see Figure 1 and Figure 2 The photovoltaic panel cleaning equipment 100 provided in this embodiment has an outlet valve 32 on the gas cylinder 30. The controller controls the flow rate of the gas ejected from the gas cylinder 30 by controlling the opening and closing degree of the outlet valve 32, thereby controlling the number of ions contained in the gas ejected from the ion nozzle 50. When the controller controls the outlet valve 32 of the gas cylinder 30 to open more, the flow rate of the gas ejected from the gas cylinder 30 is greater, thus driving more ions to be ejected from the ion nozzle 50. When the controller controls the outlet valve 32 of the gas cylinder 30 to open less, the flow rate of the gas ejected from the gas cylinder 30 is smaller, thus driving fewer ions to be ejected from the ion nozzle 50. In this way, the controller can control the flow rate of the gas ejected from the gas cylinder 30 and the number of ions ejected from the ion nozzle 50.

[0045] Please see Figure 1 The photovoltaic panel cleaning equipment 100 provided in this embodiment includes at least the following steps during the cleaning process of the photovoltaic panel:

[0046] Step 1: The drone 10 moves to propel the photovoltaic panel cleaning equipment 100 from the base to the airspace above the photovoltaic panels. The drone 10 can coordinate with the photovoltaic panel cleaning equipment 100, allowing the operator to remotely control the drone 10 to accurately propel the equipment from the base to the airspace above the photovoltaic panels.

[0047] Step 2: The controller controls the movement of the joint module 22 of the lower-mounted component 20 according to the tilt angle of the photovoltaic panel, so that the spray angle of the ion nozzle 50 matches the tilt angle of the photovoltaic panel. Specifically, the controller controls the rotation of the joint module 22 to match the spray angle of the ion nozzle 50 with the tilt angle of the photovoltaic panel.

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

[0049] Step 4: The drone 10 drives the photovoltaic panel cleaning equipment 100 to move relative to the photovoltaic panel, ensuring that the distance between the ion nozzle 50 and the photovoltaic panel remains constant, and 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 equipment 100 to move relative to the photovoltaic panel along the length or width of the photovoltaic panel.

[0050] Step 5: The drone 10 propels the photovoltaic panel cleaning equipment 100 from the photovoltaic panel to its return base. The drone 10, in conjunction with the photovoltaic panel cleaning equipment 100, flies from above the photovoltaic panel to the base. This can be achieved through remote control of the drone 10, which can precisely guide the cleaning equipment 10 from the base to the photovoltaic panel. Furthermore, when cleaning is required for photovoltaic panels at multiple different base stations, after step 4, the drone 10 can propel the cleaning equipment 100 from one base station to another.

[0051] Please see Figure 1 and Figure 3 , Figure 3 This is an assembly diagram of a hanging component provided in one embodiment of this application.

[0052] In one embodiment, the photovoltaic panel cleaning device 100 further includes sensors for sensing the tilt angle of the ion nozzle 50 relative to the photovoltaic panel and generating first sensing information, and for sensing the amount of charge on the photovoltaic panel and generating second sensing information. The controller controls the joint module 22 to move according to the first sensing information, so that the spray angle of the ion nozzle 50 adapts to the tilt angle of the photovoltaic panel. The controller is also used to control the flow rate of the gas ejected 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 sensors can be installed on the mounting frame 21 of the lower assembly 20 or on the periphery of the ion nozzle 50; this application does not limit this.

[0053] The photovoltaic panel cleaning equipment 100 provided in this embodiment acquires first and second sensing information through sensors to make the first and second sensing information more accurate. This allows the controller to more precisely control the movement of the joint module 22 and the flow rate of the gas ejected from the gas cylinder 30. This ensures that the spray angle of the ion nozzle 50 is better matched with the tilt angle of the photovoltaic panel, and that the flow rate of the gas ejected from the gas cylinder 30 can thoroughly clean the floating dust accumulated on the photovoltaic panel. It also allows the number of ions ejected from the gas cylinder 30 to neutralize the charge on the photovoltaic panel. Therefore, while saving gas consumption of the gas cylinder 30, the acquisition of the first and second sensing information through sensors helps to improve the cleaning quality of the photovoltaic panel cleaning equipment 100, thereby improving the photoelectric conversion efficiency of the photovoltaic panel.

[0054] Please see Figure 1 In this embodiment, the photovoltaic panel cleaning equipment 100 has a controller mounted on the mounting frame 21 of the lower component 20. The controller can be directly electrically connected to the sensor to obtain the signal emitted by the sensor. It is understood that in some other embodiments, the controller can be a remote control-like structure configured for the operator. The operator processes the signal emitted by the sensor and remotely controls the photovoltaic panel cleaning equipment 100 by operating the controller. This application does not limit this.

[0055] Please see Figures 1 to 3 The photovoltaic panel cleaning equipment 100 provided in this embodiment includes sensors including a position sensor (not shown) and a charge sensor (not shown). The position sensor is used at least to acquire the tilt angle of the photovoltaic panel and the spray angle of the ion nozzle 50 to form first sensing information. The controller controls the joint module 22 to move according to the first sensing information, so as to adjust the spray angle of the ion nozzle 50 to match the tilt angle of the photovoltaic panel. The charge sensor is used at least to acquire the amount of charge after the floating dust accumulates on the photovoltaic panel to form second sensing information. The controller controls the opening and closing degree of the gas cylinder 30's outlet valve 32 according to the second sensing information, so that the number of ions sprayed with the ion nozzle 50 can completely neutralize the charge after the floating dust accumulates on the photovoltaic panel.

[0056] Understandably, in some other embodiments, the sensor also includes an image sensor, which is at least used to acquire the degree of dust accumulation on the photovoltaic panel to form third sensing information. The controller can use the third sensing information to control the opening and closing of the gas outlet valve 32 of the gas cylinder 30 so that the gas ejected from the ion nozzle 50 can completely blow away the dust accumulated on the photovoltaic panel. This application does not limit this.

[0057] Please see Figures 1 to 4 , Figure 4This application provides a partial assembly of a photovoltaic panel cleaning device according to one embodiment. Figure 2 .

[0058] In one embodiment, the hanging assembly 20 of the photovoltaic panel cleaning equipment 100 further includes a connecting rod 23. The connecting rod 23 includes a first end 231 and a second end 232 disposed opposite to each other. A joint module 22 is connected at the middle position of the first end 231 and the second end 232. A controller controls the joint module 22 to adjust the position of the connecting rod 23 relative to the photovoltaic panel so that the connecting rod 23 is parallel to the photovoltaic panel. Taking a rectangular plate-shaped structure of the photovoltaic panel as an example, the controller controlling the joint module 22 to adjust the position of the connecting rod 23 relative to the photovoltaic panel includes 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 controller controlling the joint module 22 to adjust the position of the connecting rod 23 relative to the photovoltaic panel also includes 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 the plane on which the photovoltaic panel is located. The photovoltaic panel cleaning equipment 100 has multiple ion nozzles 50, which are arranged at intervals along the first end 231 to the second end 232 of the connecting rod 23. The photovoltaic panel cleaning equipment 100 also includes multiple adjusting components 60. Each adjusting component 60 connects one ion nozzle 50 to the connecting rod 23. The adjusting component 60 is used to adjust the position of the ion nozzle 50 relative to the photovoltaic panel so that the spray direction of each ion nozzle 50 is perpendicular to the photovoltaic panel. After the controller controls the articulated motor module to adjust the connecting rod 23 to a state parallel to the photovoltaic panel, the controller controls each adjusting component 60 to adjust the position of the connected ion nozzle 50 relative to the photovoltaic panel so that the spray direction of each ion nozzle 50 is perpendicular to the photovoltaic panel.

[0059] The photovoltaic panel cleaning equipment 100 provided in this embodiment, in a first aspect, uses a controller to control the joint module 22 to adjust the connecting rod 23 so that the connecting rod 23 is parallel to the photovoltaic panel. Furthermore, multiple spaced-apart ion nozzles 50 are provided on the connecting rod 23 along the direction from the first end 231 to the second end 232. Thus, when the drone 10 moves the connecting rod 23 in a direction parallel to the photovoltaic panel and perpendicular to the connecting rod 23, the multiple ion nozzles 50 can spray gas and ions to clean the entire surface of the photovoltaic panel, which helps improve the cleaning efficiency of the photovoltaic panel cleaning equipment 100. In a second aspect, an adjustment component 60 is connected to the connecting rod 23 and one ion nozzle 50. Under the action of the adjustment component 60, the spray direction of each ion nozzle 50 is perpendicular to the photovoltaic panel. This helps improve the cleaning quality of the photovoltaic panel by the gas and ions sprayed by the ion nozzles 50, reduces residual dust on the photovoltaic panel, and thus improves the photoelectric conversion efficiency of the photovoltaic panel.

[0060] Please see Figure 1 It is understood that in some other embodiments, in order to prevent the gas and ions ejected by the ion nozzle 50 from blowing dust onto the area of ​​the photovoltaic panel that has been cleaned, the spray direction of the ion nozzle 50 is at an obtuse angle to the flight direction of the drone 10, that is, the spray direction of the ion nozzle 50 is set at an angle relative to the photovoltaic panel. This application does not limit this.

[0061] Please see Figures 1 to 5 , Figure 5 yes Figure 4 The diagram shows an enlarged view of the photovoltaic panel cleaning equipment at point A.

[0062] In one embodiment, the adjustment component 60 of the photovoltaic panel cleaning equipment 100 includes a connector 61 and a first movable component 62. The connector 61 is fixedly connected to the connecting rod 23, and the first movable component 62 is rotatably connected to the connector 61 around a first axis L1. An ion nozzle 50 is fixedly connected to the first movable component 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 articulated module to adjust the connecting rod 23 to a state parallel to the photovoltaic panel, the controller can further control the first movable component 62 to rotate relative to the connector 61 around the first axis L1, thereby adjusting the spray direction of the ion nozzle 50 relative to the tilt angle of the photovoltaic panel.

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

[0064] Please see Figures 1 to 6 , Figure 6 This is an assembly diagram of an ion nozzle and adjustment assembly provided in one embodiment of this application.

[0065] In one specific embodiment, the connector 61 of the adjusting assembly 60 is provided with an annular groove 611 extending circumferentially around a first axis L1, and the annular groove 611 penetrates the connector 61 along the direction of the first axis L1. The first movable member 62 is provided with a fixed part 621 and a movable part 622. The fixed part 621 is rotatably connected to the connector 61, and the connection between the fixed part 621 and the connector 61 is located on the first axis L1. The movable part 622 passes through the annular groove 611 and can move circumferentially around the first axis L1 within the annular groove 611, so that the first movable member 62 can rotate relative to the connector 61 around the first axis L1, thereby facilitating the adjusting assembly 60 to adjust the tilt angle of the ion nozzle 50 relative to the photovoltaic panel. The fixed part 621 is detachably connected to the connector 61, and the movable part 622 is detachably connected to the annular groove 611. Simultaneously, to reduce the overall weight of the adjusting assembly 60, the connector 61 and the first movable member 62 can be provided with weight-reducing holes.

[0066] Please see Figures 1 to 8 , Figure 7 This is a schematic diagram of the assembly of the connector and the first movable member according to an embodiment of this application. Figure 1 , Figure 8 This is a schematic diagram of the assembly of the connector and the first movable member according to an embodiment of this application. Figure 2 .

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

[0068] Specifically, the first positioning part 612 is a through hole provided on the connector 61, and the second positioning part 623 is a through hole provided on the first movable part 62. When the first positioning part 612 and the second positioning part 623 are aligned, a retaining member can be used to hold the first positioning part 612 and the second positioning part 623 in place, so as to keep the first movable part 62 in a zero-point positioning state relative to the connector 61. At this time, the movable part 622 is in the middle position of the annular groove 611, that is, the angle of clockwise rotation of the movable part 622 around the first axis L1 in the annular groove 611 is equal to the angle of counterclockwise rotation of the movable part 622 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 arranged circumferentially opposite each other along the first axis L1. When the first movable member 62 is in a zero-point positioning state relative to the connecting member 61, the distance between the movable part 622 and the first wall surface 6111 of the annular groove 611 in the circumferential direction of the first axis L1 is equal to the distance between the movable part 622 and the second wall surface 6112 of the annular groove 611.

[0069] A first positioning part 612 is provided on the connector 61, and a second positioning part 623 is provided on the first movable part 62. When the first positioning part 612 and the second positioning part 623 are aligned, the first movable part 62 is in a zero-point positioning state relative to the connector 61. At this time, the movable part 622 is located in the annular groove 611 and can rotate clockwise or counterclockwise around the first axis L1. Moreover, the angle of clockwise rotation of the movable part 622 around the first axis L1 in the annular groove 611 is equal to the angle of counterclockwise rotation of the movable part 622 around the first axis L1 in the annular groove 611. Therefore, when the photovoltaic panel cleaning equipment 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 part 622 in the annular groove 611 and the counterclockwise rotation angle of the movable part 622 in the annular groove 611 to make the ion nozzle 50 adaptable to photovoltaic panels with different tilt angles. When the active part 622 is controlled by the controller, it can also simplify the program algorithm design for adjusting the rotation angle of the ion nozzle 50 by the adjustment component 60, and make the program stability of the adjustment component 60 adjusting the rotation angle of the ion nozzle 50 better.

[0070] Please see Figures 1 to 6In one specific embodiment, the adjustment assembly 60 further includes a rotating component 63 and a second movable component 64. The housing 631 of the rotating component 63 is fixedly connected to the second movable component 64, and the output shaft 632 of the rotating component 63 is connected to the second movable component 64. The rotating component 63 is used to drive the second movable component 64 to rotate around the second axis L2, and the ion nozzle 50 is fixedly connected to the second movable component 64. In this embodiment, the rotating component 63 is a servo motor, 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 articulated module to adjust the connecting rod 23 to a state parallel to the photovoltaic panel, the controller can further control the rotating component 63 to drive the second movable component 64 to rotate around the first axis L1, thereby adjusting the tilt angle of the spray direction of the ion nozzle 50 relative to the photovoltaic panel.

[0071] The photovoltaic panel cleaning equipment 100 provided in this embodiment has two aspects. First, by adjusting the second movable part 64 of the adjustment component 60, it can rotate around the second axis L2, allowing the adjustment component 60 to more precisely adjust the spray direction of the ion nozzle 50. This enables the ion nozzle 50 to adapt to different tilt directions of photovoltaic panels, improving the cleaning effect of the gas and ions sprayed by the ion nozzle 50 on the photovoltaic panel and enhancing the compatibility of the photovoltaic panel cleaning equipment 100 in cleaning photovoltaic panels with different tilt angles. Second, during the cleaning process of the photovoltaic panel cleaning equipment 100, the rotating part 63 can drive the ion nozzle 50 to rotate around the second axis L2, adjusting the spray direction of the gas and ions sprayed by the ion nozzle 50. This allows the area between two adjacent ion nozzles 50 to also be cleaned by the gas and ions, improving the cleaning quality of the photovoltaic panel cleaning equipment 100 on the photovoltaic panel.

[0072] Please see Figures 1 to 8 In some embodiments, at least a portion of the first movable member 62 and the second movable member 64 overlap along the second axis L2. The first movable member 62 is provided with a third positioning part (not shown in the figure), and the second movable member is provided with a fourth positioning part (not shown in the figure). When the first positioning part 612 and the second positioning part 623 are aligned, the spray direction of the ion nozzle 50 mounted 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 one specific embodiment, the third positioning part is a through hole provided on the first movable member 62, and the fourth positioning part is a through hole provided on the second movable member 64. When the first positioning part 612 and the second positioning part 623 are aligned, the third and fourth positioning parts can be locked by a retaining member to keep the second movable member 64 in a relatively fixed state relative to the first movable member 62. At this time, the spray direction of the ion nozzle 50 is perpendicular to the photovoltaic panel, and the angle by which the rotating member 63 drives the second movable member 64 and the ion nozzle 50 to rotate clockwise around the second axis L2 is equal to the angle by 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 and fourth positioning parts are the same as those of the first positioning part 612 and the second positioning part 623, and will not be elaborated here. Designers can flexibly design the third and fourth positioning parts according to the design principles of the first positioning part 612 and the second positioning part 623.

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

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

[0076] Please see Figures 1 to 9 , Figure 9It is a structural diagram of a first movable member provided by an embodiment of the present application.

[0077] In a specific embodiment, the first movable member 62 has a first receiving cavity 624, and the first receiving cavity 624 is in a "C" shape. The housing 631 of the rotating member 63 is received in the first receiving cavity 624. Due to the first receiving cavity 624 of the first movable member 62 being in a "C" shape, it is convenient for the housing 631 of the rotating member 63 to be received and fixed in the first receiving cavity 624. So that 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 further can drive the ion air nozzle 50 to rotate around the first axis L1 relative to the connecting member 61. Moreover, the second movable member 64 has a second receiving cavity 641, and the second receiving cavity 641 is in a "C" shape. The second receiving cavity 641 includes a first inner wall and a second inner wall that are oppositely 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] For the photovoltaic panel cleaning device 100 provided by this embodiment, due to the second receiving cavity 641 of the second movable member 64 being in a "C" shape, it is convenient for the output shaft 632 of the rotating member 63 to be received in the second receiving cavity 641, and it is also convenient for the opposite ends of the output shaft 632 of the rotating member 63 to be respectively and fixedly connected to the first inner wall and the second inner wall, so that when the second movable member 64 rotates around the second axis L2, it can drive the ion air nozzle 50 to rotate around the second axis L2, and further can make the spraying direction of the ion air nozzle 50 be adjusted to a direction perpendicular to the photovoltaic panel.

[0079] It can be understood that in some other embodiments, the first receiving cavity 624 can be in a "mouth" shape, so that the housing 631 of the rotating member 63 has better stability when fixed in the first receiving cavity 624. The present application does not limit this.

[0080] Please refer to Figures 1 to 6In one specific embodiment, the dimension of the first movable member 62 along the second axis L2 is smaller than the dimension of the second receiving cavity 641 along the second axis L2. During the process of the rotating member 63 driving the second movable member 64 to rotate around the second axis L2, rotational interference between the first movable member 62 and the second movable member 64 can be avoided, thus preventing the rotation angle of the second movable member 64 from being limited. Therefore, the rotation angle of the second movable member 64 around the second axis L2 can be larger, which in turn allows the rotating member 63 to 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 angles, improving the cleaning compatibility of the photovoltaic panel cleaning equipment 100 for photovoltaic panels with different tilt angles. Simultaneously, the larger rotation angle of the ion nozzle 50 driven by the rotating member 63 around the second axis L2 allows for a wider spray angle range of the ion nozzle 50. The gas and ions sprayed by the ion nozzle 50 can completely cover the area between two adjacent ion nozzles 50 corresponding to the photovoltaic panel, improving the cleaning quality of the photovoltaic panel cleaning equipment 100.

[0081] Please see Figures 1 to 6 In one specific embodiment, along the direction of the second axis L2, a portion of the ion nozzles 50 are stacked and fixedly connected to the second movable member 64, while another portion of the ion nozzles 50 are suspended in the air. Furthermore, the portion of the ion nozzles 50 fixedly connected to the second movable member 64 is spaced apart from the connecting member 61. Therefore, during the rotation of the ion nozzles 50 around the second axis L2 under the influence of the rotating member 63, rotational interference between the ion nozzles 50 and the connecting member 61 can be avoided, thus preventing a limitation on the rotation angle of the ion nozzles 50. The rotation angle of the ion nozzles 50 around the second axis L2 can be larger, allowing them to adapt to photovoltaic panels with different tilt angles, thereby improving the cleaning compatibility of the photovoltaic panel cleaning equipment 100 for photovoltaic panels with different tilt angles.

[0082] Please see Figures 1 to 10 , Figure 10 This is a structural diagram of a second movable component provided in an embodiment of this application.

[0083] In one specific embodiment, the second movable component 64 includes a first part 642, a second part 643, and a third part 644, which are separately arranged and connected sequentially. The first part 642 includes a first plate 6421, a second plate 6422, and a third plate 6423 connected in a "C" shape. The first plate 6421 and the third plate 6423 are arranged opposite each other along a second axis L2, and the first plate 6421, the second plate 6422, and the third plate 6423 surround to form a second receiving cavity 641. A portion of the ion nozzle 50 is fixed to the outer side wall of the first plate 6421. The second part 643 is plate-shaped, coplanar with the first plate 6421, and spaced apart from the first part 642. Another portion of the ion nozzle 50 is fixed to one side of the second part 643. The third part 644 is plate-shaped, with one side fixedly connected to the outer wall of the second plate 6422, and the other side fixedly connected to the side of the second part 643 opposite to the ion nozzle 50. It is 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 may be an integral structure, and this application does not limit this.

[0084] The photovoltaic panel cleaning equipment 100 provided in this embodiment has its first plate 6421 of the second part 643 and the third part 644 arranged coplanarly to facilitate the installation of the ion nozzle 50 on the first part 642 and the second part 643. Simultaneously, 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 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 opposite to the ion nozzle 50, so that the third part 644 provides support for the second part 643, which helps improve the stability of the ion nozzle 50 during installation on the second part 643.

[0085] The above are some embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
