Description

Technical Field

[0001] The present invention belongs to the field of photovoltaic panels, and in particular relates to a microgrid photovoltaic panel corridor cleaning system and a control method thereof. Background Art

[0002] Photovoltaic panels are devices that can convert solar energy into electrical energy. They are widely used in power supply for household roofs, commercial buildings, public facilities, and remote areas. Traditional maintenance of photovoltaic panels usually involves manual wiping and cleaning. With the development of technology, equipment that automatically cleans photovoltaic panels has also emerged. However, in order to facilitate the collection of dirt generated by cleaning, for tilted photovoltaic panels, photovoltaic panel automatic cleaning equipment usually uses a top-down method to reciprocate and clean the photovoltaic panels. The cleaning efficiency is low, and it is impossible to use one set of equipment to achieve continuous cleaning of the entire photovoltaic panel corridor. Summary of the invention

[0003] The present invention provides a microgrid photovoltaic panel corridor cleaning system and a control method thereof, so as to solve the problem that the cleaning efficiency of the current photovoltaic panel automatic cleaning equipment is low and the overall continuous cleaning of the photovoltaic panel corridor cannot be achieved by using a set of equipment.

[0004] According to a first aspect of an embodiment of the present invention, a microgrid photovoltaic panel corridor cleaning system is provided, comprising a photovoltaic panel corridor, a detection device, a driving device, a dust forming component and a water washing cleaning component, wherein when cleaning along the corridor direction, the dust forming component is located in front of the water washing cleaning component and behind the detection device, wherein a direction perpendicular to the corridor direction and parallel to the photovoltaic panel is a first direction;

[0005] The controller is respectively connected to the detection device, the driving device, the dust forming component and the water washing and cleaning component. After receiving the cleaning instruction, the controller controls the driving device to drive the detection device, the dust forming component and the water washing and cleaning component to move synchronously and continuously in the direction of the corridor, and controls the water washing and cleaning component to start cleaning at the same time, controls the dust forming component to move in the first direction so that the dust on the photovoltaic panel is formed during the movement of the dust forming component, and determines the position of the adhesion block according to the current position of the detection device when the detection device detects the adhesion block. When the dust forming component is about to move to the adhesion block, the controller controls the movement of the dust forming component in the first direction so that the adhesion block on the photovoltaic panel is removed during the movement of the dust forming component, and the formed dust body and adhesion block are pushed to the end of the photovoltaic panel by the dust forming component for collection, and the sewage generated by the water washing and cleaning component flows to the lower end of the photovoltaic panel for collection.

[0006] In an optional implementation, the detection device includes a first motor, the shaft of which is arranged along the first direction and the bases at the upper and lower ends are respectively clamped on the guide rails at the upper and lower ends of the photovoltaic panel corridor, so that the first motor can slide along the direction of the corridor. The first motor is also provided with a detection plate, which is spaced apart from the photovoltaic panel corridor, and a distributed pressure sensing optical fiber is arranged on the first and second surfaces of the detection plate facing and away from the end of the photovoltaic panel, wherein the distributed pressure sensing optical fiber on each surface is composed of a plurality of connected optical fiber segments, each optical fiber segment is parallel to each other and each optical fiber segment is arranged along the first direction, a free end of the distributed pressure sensing optical fiber is connected to the sensing component, in an initial state, the detection plate is arranged perpendicular to the photovoltaic panel corridor, the direction on the detection plate perpendicular to the first direction is the second direction, and the detection plate extends along the second direction and can pass through the shaft of the first motor; the base of the first motor is also fixedly connected to a first water spraying mechanism arranged along the first direction, and the first water spraying mechanism is arranged behind the first motor.

[0007] In another optional implementation, the controller is connected to the first motor, the sensor assembly and the first water spray mechanism respectively. When the sensor assembly determines that the detection piece detects pressure on the optical fiber segment on the first side facing the end of the photovoltaic panel, it means that the adhesive block is detected. At this time, the position of the adhesive block in the direction of the corridor is determined according to the current position of the first motor; the height of the adhesive block is determined according to the position of the optical fiber segment on the first side where the pressure is detected in the second direction, and the position and width of the adhesive block in the first direction are determined according to the position and length of the part on the optical fiber segment where the pressure is detected in the first direction;

[0008] After the adhesive block is detected, the driving device is continuously controlled to drive the detection device to move a corresponding distance along the direction of the corridor, and the viscosity of the adhesive block is determined according to the pressure change detected by the optical fiber segment on the first surface during this process;

[0009] Thereafter, the first motor is controlled to rotate in a direction opposite to the adhesive block until the optical fiber segment on the second surface of the detection sheet away from the end of the photovoltaic panel detects pressure, and the length of the adhesive block is determined according to the position of the optical fiber segment on the first surface that detects pressure in the second direction, the position of the optical fiber segment on the second surface that detects pressure in the second direction, and the distance from the detection of the adhesive block to the current end of the movement of the first motor;

[0010] Determine the volume of the adhesive block according to the height, width and length of the adhesive block;

[0011] According to the position of the adhesive block in the direction of the corridor and the length of the adhesive block, it is determined whether the first water spraying mechanism moves to the middle position of the adhesive block. When the first water spraying mechanism moves to the middle position of the adhesive block, a corresponding amount of water is sprayed according to the volume and viscosity of the adhesive block.

[0012] In another optional implementation, while continuing to control the driving device to drive the detection device to move a corresponding distance along the direction of the corridor, if the adhesive block has a low viscosity to the photovoltaic panel, the adhesive block will be peeled off during the movement of the detection device along the direction of the corridor, and the pressure change detected by the optical fiber segment on the first surface is 0;

[0013] If the adhesive block has a high viscosity to the photovoltaic panel, the adhesive block will always act on the optical fiber segment on the first surface, and the pressure detected by the optical fiber segment on the first surface is always greater than 0. In view of the fact that the pressure detected by the optical fiber segment on the first surface is always greater than 0, the viscosity of the adhesive block is further determined based on the magnitude of the detected pressure change: when the detected pressure increase is large, it means that the adhesive block has a small viscosity and a large hardness; when the detected pressure increase is small, it means that the adhesive block has a large viscosity and a small hardness.

[0014] In another optional implementation, when determining the position of the optical fiber segment on the first surface where the pressure is detected in the second direction, the distance between the position and the axis of the second motor in the second direction is H1, and when determining the position of the optical fiber segment on the second surface where the pressure is detected in the second direction, the distance between the position and the axis of the second motor in the second direction is H2, and the distance moved by the second motor from the detection of the adhesive block to the current end is H3, then the length of the adhesive block is equal to

[0015]

[0016] In another optional implementation, when the detected pressure increase is large, it means that the viscosity of the adhesive block is small and the hardness is large. When a corresponding amount of water is sprayed according to the volume and viscosity of the adhesive block, the amount of water sprayed is increased; when the detected pressure increase is small, it means that the viscosity of the adhesive block is large and the hardness is small. When a corresponding amount of water is sprayed according to the volume and viscosity of the adhesive block, no water is sprayed or the amount of water sprayed is reduced.

[0017] In another optional implementation, the dust forming assembly includes a scraper, an electric telescopic rod, and a first telescopic rod arranged opposite to the electric telescopic rod, the scraper is a sawtooth structure parallel to the photovoltaic panel gallery and arranged along the first direction, the sawtooth structure is formed by connecting a plurality of sawtooths with the same structure, and a water immersion pipe is arranged on the back of the sawtooth along the path where the sawtooth is located, and an opening is provided in the recess in each tooth in front of the sawtooth structure facing the end of the photovoltaic panel, so that the water immersion pipe can immerse water into the front recess of the sawtooth through the opening;

[0018] The bases of the electric telescopic rod and the first telescopic rod are respectively clamped on the guide rails at the upper and lower ends of the photovoltaic panel corridor, and are respectively fixedly connected to the upper and lower ends of the scraper, and the two are used to control the movement of the scraper in the first direction; the electric telescopic rod is also connected to the driving device. After receiving the cleaning instruction, the controller controls the driving device to drive the electric telescopic rod to move continuously in the direction of the corridor, and controls the electric telescopic rod to drive the scraper to move in the first direction, so that the dust scraped from the photovoltaic panel by the scraper gradually gathers toward the front depression of the sawtooth structure, and the gathered dust is formed under the action of immersion in water.

[0019] In another optional implementation, when the dust forming assembly is moving along the corridor, except when it is about to move to the adhesion block, the controller controls the electric telescopic rod to extend and retract by the same length, so that the scraper moves back and forth in the first direction;

[0020] The controller determines whether the plane where the front tooth tips of the sawtooth structure are located is in contact with the adhesion block. If so, it is determined that the dust forming component is about to move to the adhesion block. At this time, the electric telescopic rod is first controlled to extend and retract to drive the sawtooth structure to move in the first direction, so that the adhesion block is located in the corresponding sawtooth, and the lower tooth tip of the sawtooth abuts against the lower end of the adhesion block in the first direction; then, according to the width of the adhesion block, the electric telescopic rod is controlled to drive the sawtooth structure to move downward in the first direction until the upper teeth of the sawtooth abut against the upper end of the adhesion block. During this process, the dust scraped off by the sawtooth structure will adhere to the adhesion block, so as to facilitate the peeling of the adhesion block from the photovoltaic panel and avoid the adhesion block from adhering to the photovoltaic panel again during the peeling process; finally, the electric telescopic rod is controlled to drive the sawtooth structure to move in the first direction, and the adhesion block is peeled off from the photovoltaic panel by the lower teeth of the sawtooth, and the peeled adhesion block is gathered toward the front depression of the sawtooth, so as to avoid the adhesion block from sliding out from the lower end of the photovoltaic panel during the peeling process.

[0021] In another optional implementation, the water-washing and cleaning component includes a cleaning piece, a second motor and a second water spraying mechanism, the cleaning piece wraps around the rotating drum of the second motor and abuts against the photovoltaic panel, the second motor can drive the cleaning piece to rotate and the rotating shaft is arranged along the first direction; the upper and lower ends of the second motor are respectively clamped on the guide rails at the upper and lower ends of the photovoltaic panel corridor, the upper and lower ends of the second water spraying mechanism are respectively fixed on the base of the second motor and are used to spray water on both sides of the second motor, the driving device is fixedly connected to the base of the second motor, and is used to drive the second motor and the cleaning piece and the second water spraying mechanism thereon to move in the direction of the corridor; the controller is respectively connected to the second motor and the second water spraying mechanism, and is used to control the second water spraying mechanism to spray water on both sides of the cleaning piece when the water-washing and cleaning component starts cleaning; and when the cleaning piece moves a corresponding distance along the corridor direction, the second motor is controlled to rotate a corresponding angle so that other positions of the cleaning piece abut against the photovoltaic panel.

[0022] According to a second aspect of an embodiment of the present invention, a control method for the above-mentioned microgrid photovoltaic panel corridor cleaning system is also provided, including:

[0023] Step S100, after receiving the cleaning instruction, the controller controls the driving device to drive the detection device, the dust forming component and the water washing cleaning component to move synchronously and continuously in the direction of the corridor, and at the same time controls the water washing cleaning component to start cleaning, and controls the dust forming component to move in the first direction, so that the dust on the photovoltaic panel is formed during the movement of the dust forming component;

[0024] Step S200, determining the position of the adhesion block according to the current position of the detection device when the detection device detects the adhesion block, and controlling the movement of the dust forming component in the first direction when the dust forming component is about to move to the adhesion block, so that the adhesion block on the photovoltaic panel is removed during the movement of the dust forming component, and the formed dust body and adhesion block are pushed to the end of the photovoltaic panel by the dust forming component for collection, and the wastewater generated by the water washing and cleaning component flows to the lower end of the photovoltaic panel for collection.

[0025] The beneficial effects of the present invention are:

[0026] 1. The present invention not only has a water-washing and cleaning component, but also has a detection device and a dust-forming component. The dust on the photovoltaic panel is formed by the dust-forming component, and the movement of the dust-forming component in the first direction is controlled according to the state of the adhesion block on the photovoltaic panel detected by the detection device, so that the adhesion block is removed from the photovoltaic panel. The formed dust body and adhesion block are pushed to the end of the photovoltaic panel by the dust-forming component for collection, and the sewage generated by the water-washing and cleaning component flows to the lower end of the photovoltaic panel for collection. Since the dust-forming component is located in front of the water-washing and cleaning component, the present invention performs triple cleaning, the first is to form and clean the dust, the second is to remove and clean the adhesion block, and the third is to wash and clean the remaining dirt on the photovoltaic panel. It can be seen that the present invention greatly improves the cleaning effect; since the cleaning direction of the present invention is the direction of the corridor, Therefore, the cleaning of the entire photovoltaic panel corridor can be completed by using a set of equipment for one cleaning, and the cleaning efficiency is high; because the present invention has undergone two-step cleaning when washing the dirt on the photovoltaic panel, the water resources consumed during washing and cleaning are greatly reduced; in the present invention, the dust body and the adhesion block as solid are pushed to the end of the photovoltaic panel for collection, and the sewage as liquid flows to the lower end of the photovoltaic panel for collection, which can reduce the amount of dirt dissolved in the water, reduce the difficulty of sewage treatment, and improve the environmental protection of photovoltaic panel cleaning; in addition, the detection device, dust forming component and water washing cleaning component of the present invention move synchronously and continuously in the direction of the corridor, and the positional relationship between the three is fixed, so that the current position of the detection device can be accurately determined, thereby accurately determining the position of the adhesion block and whether the dust forming component is about to move to the adhesion block;

[0027] 2. The present invention can detect the position of the adhesive block in the corridor direction and the first direction respectively by setting a detection device, and can determine the length, width and height of the adhesive block, thereby determining the volume of the adhesive block. Thereafter, the amount of water provided to the adhesive block by the first water spraying mechanism can be determined according to the volume and viscosity of the adhesive block. When determining the amount of water sprayed, the present invention still controls the first motor to move a corresponding distance along the corridor direction after detecting the adhesive block. In this way, when the viscosity of the adhesive block is low, it can be directly peeled off. When the viscosity of the adhesive block is high, the viscosity of the adhesive block can be determined according to the pressure change detected by the optical fiber segment on the first surface of the detection sheet. If the detected pressure is If the force increase is large, it means that the viscosity of the adhesive block is small and the hardness is large, but the detection sheet acts on the adhesive block and still cannot make the adhesive block peel off from the photovoltaic panel. At this time, the water spraying amount can be increased according to the volume and viscosity of the adhesive block (by increasing the opening of the water spray valve in the first water spraying mechanism, etc.); if the pressure increase detected is small, it means that the viscosity of the adhesive block is large and the hardness is small, but the detection sheet still cannot make the adhesive block peel off from the photovoltaic panel. At this time, water spraying is not required or the water spraying amount is reduced. The present invention provides a precise amount of water to the adhesive block, which can reduce the waste of water resources while ensuring that the adhesive block can be peeled off under the action of the subsequent dust forming component;

[0028] 3. The present invention can scrape dust off the photovoltaic panel by setting a dust molding component and can shape the scraped dust by controlling the movement of the dust molding component. In addition, when peeling off the adhesive block, by further controlling the movement of the dust molding component, the adhesive block can be more easily peeled off and the peeled adhesive block can be wrapped by dust, which can prevent the adhesive block from adhering to the photovoltaic panel again.

[0041] See also Figure 1, which is a structural schematic diagram of an embodiment of a microgrid photovoltaic panel corridor cleaning system of the present invention. The microgrid photovoltaic panel corridor cleaning system may include a photovoltaic panel corridor 1, a detection device 2, a drive device 3, a dust forming component 4 and a water washing cleaning component 5. When cleaning along the corridor direction, the dust forming component 4 is located in front of the water washing cleaning component 5 and behind the detection device 2. Each photovoltaic panel in the photovoltaic panel corridor 1 can be tilted and located on the same plane, wherein the direction perpendicular to the corridor direction and parallel to the photovoltaic panel is the first direction; the controller can be connected to the detection device 2, the drive device 3, the dust forming component 4 and the water washing cleaning component 5 respectively, and after receiving the cleaning instruction, it controls the drive device 3 to drive the detection device 2, the dust forming component 4 and the water washing cleaning component 5 to move synchronously and continuously in the corridor direction, At the same time, the water washing and cleaning component 5 is controlled to start cleaning, and the dust forming component 4 is controlled to move in a first direction perpendicular to the direction of the corridor, so that the dust on the photovoltaic panel is formed during the movement of the dust forming component 4, and the position of the adhesion block is determined according to the moving position of the detection device 2 when the detection device 2 detects the adhesion block. When the dust forming component 4 is about to move to the adhesion block, the movement of the dust forming component 4 in the first direction is controlled, so that the adhesion block on the photovoltaic panel is removed during the movement of the dust forming component 4, and the formed dust body and adhesion block are pushed to the end of the photovoltaic panel by the dust forming component 4 for collection, and the sewage generated by the water washing and cleaning component 5 flows to the lower end of the photovoltaic panel for collection.

[0042] In this embodiment, the upper and lower ends of the photovoltaic panel corridor 1 can be respectively provided with mutually parallel guide rails 11. Figures 2 to 4As shown, the detection device 2 may include a first motor 21, the rotating shaft of the first motor 21 is arranged along the first direction and the bases at the upper and lower ends are respectively clamped on the guide rails 11 at the upper and lower ends of the photovoltaic panel gallery 1, so that the first motor 21 can slide along the direction of the gallery, and the first motor is also provided with a detection piece 22, the detection piece 22 is spaced apart from the photovoltaic panel gallery 1, and a distributed pressure sensing optical fiber 23 is arranged on the first surface and the second surface of the detection piece 22 facing and away from the end of the photovoltaic panel, wherein the distributed pressure sensing optical fiber on each surface can be composed of a plurality of connected optical fiber segments, each optical fiber segment is parallel to each other and each optical fiber segment is arranged along the first direction, a free end of the distributed pressure sensing optical fiber is connected to the sensing component 24, in the initial state, the detection piece 22 is arranged perpendicular to the photovoltaic panel gallery 1, the direction on the detection piece 22 perpendicular to the first direction is the second direction, and the detection piece 22 extends along the second direction through the rotating shaft of the first motor 21. The base of the first motor 21 is also fixedly connected to a first water spray mechanism 25 (such as a water spray pipe with multiple water spray holes and a water spray valve connected to the water spray pipe) arranged along the first direction, and the first water spray mechanism 25 is arranged behind the first motor 21.

[0043] The controller is connected to the first motor 21, the sensor component 24 and the first water spray mechanism 25 respectively. When the sensor component 24 determines that the optical fiber segment on the first side of the detection piece 22 facing the end of the photovoltaic panel detects pressure, it means that the adhesive block 6 is detected. At this time, the position of the adhesive block 6 in the corridor direction is determined according to the current position of the first motor 21, the height of the adhesive block 6 is determined according to the position of the optical fiber segment on the first side that detects pressure in the second direction, and the position and length of the part on the optical fiber segment that detects pressure in the first direction are determined according to the position and length of the part in the first direction where the pressure is detected. width; after detecting the adhesive block 6, continue to control the driving device to drive the detection device 2 to move a corresponding distance along the direction of the corridor, and determine the viscosity of the adhesive block according to the pressure change detected by the optical fiber segment on the first surface during this process (in this process, if the viscosity of the adhesive block to the photovoltaic panel is low, the adhesive block will be peeled off from the photovoltaic panel when the detection device moves along the direction of the corridor, and the pressure change detected by the optical fiber segment on the first surface is 0; if the viscosity of the adhesive block to the photovoltaic panel is high, the adhesive block will always act on the optical fiber segment on the first surface, and the pressure detected by the optical fiber segment on the first surface is always greater than 0, and for the first In the case where the pressure detected by the optical fiber segment on one side is always greater than 0, the viscosity of the adhesive block can be further determined based on the magnitude of the detected pressure change. When the detected pressure increase is large, it means that the viscosity of the adhesive block is small and the hardness is large. When the detected pressure increase is small, it means that the viscosity of the adhesive block is large and the hardness is small). Thereafter, the first motor 21 is controlled to rotate in the direction opposite to the adhesive block 6 until the optical fiber segment on the second side where the detection sheet 22 is away from the end of the photovoltaic panel detects pressure. At this time, according to the position of the optical fiber segment on the first side that detects pressure in the second direction, the pressure on the second side detected by the optical fiber segment The length of the adhesive block 6 is determined by the position of the optical fiber segment where the pressure is measured in the second direction and the distance from the detection of the adhesive block 6 to the current end of the movement of the first motor 21; the volume of the adhesive block 6 is determined according to the height, width and length of the adhesive block 6; according to the position of the adhesive block 6 in the corridor direction and the length of the adhesive block 6, it is determined whether the first water spraying mechanism 25 has moved to the middle position of the adhesive block 6. When the first water spraying mechanism 25 moves to the middle position of the adhesive block 6, a corresponding amount of water is sprayed according to the volume and viscosity of the adhesive block 6 to make it possible for the adhesive block 6 to be peeled off.

[0044] Combination Figure 5As shown, the solid line shows the position of the detection device when the adhesion block is detected, and the dotted line shows the current position of the detection device. Since the detection piece passes through the rotating shaft of the first motor after being extended, the distance between the free end of the detection piece and the axis of the first motor in the second direction is constant. It is assumed that when determining the position of the optical fiber segment that detects pressure on the first surface in the second direction, the distance between the position and the axis of the second motor in the second direction is H1. When determining the position of the optical fiber segment that detects pressure on the second surface in the second direction, the distance between the position and the axis of the second motor in the second direction is H2. The distance moved by the second motor from the detection of the adhesion block to the current end is H3. Then the length of the adhesion block can be equal to

[0045] The present invention can detect the position of the adhesive block in the corridor direction and the first direction respectively by setting a detection device, and can determine the length, width and height of the adhesive block, thereby determining the volume of the adhesive block. Thereafter, the amount of water provided to the adhesive block by the first water spraying mechanism can be determined according to the volume and viscosity of the adhesive block. When determining the amount of water sprayed, the present invention still controls the first motor to move a corresponding distance along the corridor direction after detecting the adhesive block. In this way, when the viscosity of the adhesive block is low, it can be directly peeled off. When the viscosity of the adhesive block is high, the viscosity of the adhesive block can be determined according to the pressure change detected by the optical fiber segment on the first surface of the detection sheet. If the detected pressure is If the increase is large, it means that the viscosity of the adhesive block is small and the hardness is large, but the detection piece still cannot make the adhesive block be peeled off from the photovoltaic panel. At this time, the water spraying amount can be increased according to the volume and viscosity of the adhesive block (by increasing the opening of the water spray valve in the first water spraying mechanism, etc.); if the detected pressure increase is small, it means that the viscosity of the adhesive block is large and the hardness is small, but the detection piece still cannot make the adhesive block be peeled off from the photovoltaic panel. At this time, water can be stopped from being sprayed or the amount of water sprayed can be reduced. The present invention provides a precise amount of water to the adhesive block, which can reduce the waste of water resources while ensuring that the adhesive block can be peeled off under the action of the subsequent dust forming component.

[0046] Combination Figure 6 and Figure 7 As shown, the dust forming assembly may include a scraper 41, an electric telescopic rod 42 and a first telescopic rod 43 arranged opposite to the electric telescopic rod 42, the scraper 41 is a sawtooth structure parallel to the photovoltaic panel corridor and arranged along the first direction, the sawtooth structure is connected by a plurality of sawtooths of the same structure, along the path where the sawtooth is located, an immersion pipe 44 is arranged on the back of the sawtooth, and in front of the sawtooth structure facing the end of the photovoltaic panel, an opening 45 is provided in the recess in each tooth, so that the immersion pipe 44 can immerse water into the front recess of the sawtooth through the opening 45.

[0047] The bases of the electric telescopic rod 42 and the first telescopic rod 43 are respectively mounted on the guide rails 11 at the upper and lower ends of the photovoltaic panel corridor 1, and are respectively fixedly connected to the upper and lower ends of the scraper 41, and the two are used to control the movement of the scraper 41 in the first direction; the electric telescopic rod 42 is also connected to the driving device 3. After receiving the cleaning instruction, the controller controls the driving device 3 to drive the electric telescopic rod 42 to continue to move in the corridor direction, and controls the electric telescopic rod 42 to drive the scraper 41 to move in the first direction, so that the dust scraped from the photovoltaic panel by the scraper 41 gradually gathers toward the front depression of the sawtooth structure, and the gathered dust is formed under the action of immersion in water. In the process of the dust forming component moving along the corridor direction, except when it is about to move to the adhesion block, the controller controls the electric telescopic rod 42 to extend and retract the same length each time, so that the scraper 41 reciprocates in the first direction.

[0048] Combination Figure 8 As shown, in order to determine whether the dust forming component is about to move to the adhesion block, the controller can determine whether the plane 46 where the front tooth tips of the sawtooth structure are located is in contact with the adhesion block 6. If so, it is determined that the dust forming component is about to move to the adhesion block. At this time, the electric telescopic rod 42 is first controlled to extend and retract to drive the sawtooth structure to move in the first direction, so that the adhesion block is located in the corresponding sawtooth, and the lower tooth tip of the sawtooth abuts against the lower end of the adhesion block in the first direction, as shown in FIG. Figure 8 (a); then, according to the width of the adhesive block, the electric telescopic rod is controlled to drive the sawtooth structure to move downward in the first direction until the upper teeth of the sawtooth abut against the upper end of the adhesive block, as shown in FIG. Figure 8 As shown in (b), during this process, the dust scraped off by the sawtooth structure will adhere to the adhesive block, so as to adjust the external viscosity of the adhesive block, thereby facilitating the peeling of the adhesive block from the photovoltaic panel and preventing the adhesive block from adhering to the photovoltaic panel again during the peeling process; finally, as shown in Figure 8 As shown in (c), the electric telescopic rod is controlled to drive the sawtooth structure to move in the first direction, and the adhesive block is peeled off from the photovoltaic panel using the lower teeth of the sawtooth, and the peeled adhesive block is gathered toward the front recess of the sawtooth, thereby preventing the adhesive block from sliding out from the lower end of the photovoltaic panel during the peeling process.

[0049] The present invention can scrape dust off the photovoltaic panel by setting up a dust molding component and can shape the scraped dust by controlling the movement of the dust molding component. In addition, when peeling off the adhesive block, by further controlling the movement of the dust molding component, the adhesive block can be more easily peeled off and the peeled adhesive block can be wrapped by dust, which can prevent the adhesive block from adhering to the photovoltaic panel again.

[0050] In addition, if Fig. 9As shown, the water-washing and cleaning component may include a cleaning member, a second motor and a second water spraying mechanism, the cleaning member wraps around the rotating drum of the second motor and abuts against the photovoltaic panel, the second motor can drive the cleaning member to rotate and the rotating shaft is arranged along the first direction; the upper and lower ends of the second motor are respectively clamped on the guide rails at the upper and lower ends of the photovoltaic panel corridor, the upper and lower ends of the second water spraying mechanism are respectively fixed on the base of the second motor and are used to spray water to both sides of the second motor, the driving device is fixedly connected to the base of the second motor, and is used to drive the second motor and the cleaning member and the second water spraying mechanism thereon to move in the direction of the corridor; the controller is respectively connected to the second motor and the second water spraying mechanism, and is used to control the second water spraying mechanism to spray water to both sides of the cleaning member when the water-washing and cleaning component starts cleaning; and the second motor is controlled to rotate a corresponding angle every time the cleaning member moves a corresponding distance along the corridor direction, so that other positions of the cleaning member abut against the photovoltaic panel.

It can be seen that the present invention greatly improves the cleaning effect; since the cleaning direction of the present invention is long The photovoltaic panel corridor is in the direction of the corridor, so the cleaning of the entire photovoltaic panel corridor can be completed by using a set of equipment for one cleaning, and the cleaning efficiency is high; because the present invention has undergone two-step cleaning when washing the dirt on the photovoltaic panel, the water resources consumed during washing and cleaning are greatly reduced; in the present invention, the dust body and the adhesion block as solid are pushed to the end of the photovoltaic panel for collection, and the sewage as liquid flows to the lower end of the photovoltaic panel for collection, which can reduce the amount of dirt dissolved in the water, reduce the difficulty of sewage treatment, and improve the environmental protection of photovoltaic panel cleaning; in addition, the detection device, the dust forming component and the water washing cleaning component of the present invention move synchronously and continuously in the direction of the corridor, and the positional relationship between the three is fixed, so the current position of the detection device can be accurately determined, thereby accurately determining the position of the adhesion block and whether the dust forming component is about to move to the adhesion block.

[0053] In addition, if Fig.10 As shown, the present invention also provides a control method for the above-mentioned microgrid photovoltaic panel corridor cleaning system, which may include:

[0054] Step S100, after receiving the cleaning instruction, the controller controls the driving device to drive the detection device, the dust forming component and the water washing cleaning component to move synchronously and continuously in the direction of the corridor, and at the same time controls the water washing cleaning component to start cleaning, and controls the dust forming component to move in the first direction, so that the dust on the photovoltaic panel is formed during the movement of the dust forming component;

The dust on the photovoltaic panel is formed by the dust forming component, and the movement of the dust forming component in the first direction is controlled according to the state of the adhesion block on the photovoltaic panel detected by the detection device, so that the adhesion block is removed from the photovoltaic panel, and the formed dust body and adhesion block are pushed to the end of the photovoltaic panel by the dust forming component for collection, while the sewage generated by the water-washing and cleaning component flows to the lower end of the photovoltaic panel for collection. Since the dust forming component is located in front of the water-washing and cleaning component, the present invention performs triple cleaning, the first stage is to shape and clean the dust, the second stage is to remove and clean the adhesion block, and the third stage is to wash and clean the remaining dirt on the photovoltaic panel. It can be seen that the present invention greatly improves the cleaning effect; since the cleaning direction of the present invention is long The photovoltaic panel corridor is in the direction of the corridor, so the cleaning of the entire photovoltaic panel corridor can be completed by using a set of equipment for one cleaning, and the cleaning efficiency is high; because the present invention has undergone two-step cleaning when washing the dirt on the photovoltaic panel, the water resources consumed during washing and cleaning are greatly reduced; in the present invention, the dust body and the adhesion block as solid are pushed to the end of the photovoltaic panel for collection, and the sewage as liquid flows to the lower end of the photovoltaic panel for collection, which can reduce the amount of dirt dissolved in the water, reduce the difficulty of sewage treatment, and improve the environmental protection of photovoltaic panel cleaning; in addition, the detection device, the dust forming component and the water washing cleaning component of the present invention move synchronously and continuously in the direction of the corridor, and the positional relationship between the three is fixed, so the current position of the detection device can be accurately determined, thereby accurately determining the position of the adhesion block and whether the dust forming component is about to move to the adhesion block.
