Automatic cleaning device for water floating photovoltaic array

Abstract

This invention discloses an automatic cleaning device for floating photovoltaic arrays, belonging to the field of photovoltaic power generation technology. This floating photovoltaic array automatic cleaning device, through the setting of a drive mechanism and a cleaning mechanism, allows liquid to flow along the second conduit on both sides and the first control valve when cleaning of the photovoltaic panels is required. When liquid enters the sealed shell, it contacts the drive fan blades, and the friction and pressure generated by the flowing liquid synchronously drive the drive fan blades, sleeve, and cleaning plate to rotate, thereby achieving the wiping effect on the photovoltaic panels. Simultaneously, the liquid flows along the drainage component connected to the surface of the sleeve to the bottom of the cleaning plate, allowing the device to spray liquid onto the photovoltaic panels while wiping them. This improves the cleaning effect of the device on the photovoltaic panels and avoids incomplete cleaning due to dust adhering too firmly to the surface of the photovoltaic panels, thus improving the cleaning efficiency of the device.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic power generation, in particular to an automatic cleaning device for a water-floating photovoltaic array. BACKGROUND

[0002] Water photovoltaic power generation belongs to a new type of energy storage, and a water photovoltaic power generation platform is generally constructed on the sea surface. Compared with the ground, the sea surface is sunny and flat, which is more conducive to the construction of a photovoltaic power station and avoids land occupation.

[0003] The current water photovoltaic power generation panel is floating on the water surface and has the characteristics of fluctuating with waves. The cleaning device of a land photovoltaic power station cannot be used for water. If a manual cleaning method is used, it is not only difficult to force on the water surface, but also difficult to clean. If the force is too large, the photovoltaic panel may be deflected or even damaged. In addition, the photovoltaic panel is located on the water surface, and the humid water vapor will firmly stick the dust on the photovoltaic panel after the dust falls on the photovoltaic panel, resulting in poor cleaning effect of the spray washing method and difficulty in ensuring the cleaning efficiency of the photovoltaic panel.

[0049] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0050] Example 1

[0051] like Figures 1-3 and Figure 6 As shown, the present invention provides a technical solution: an automatic cleaning device for a floating photovoltaic array, comprising,

[0052] The frame mechanism 100 includes a frame horizontal plate 101, connecting rods 102 connected to both sides of the frame horizontal plate 101, frame vertical plates 103, and drain ports 104. There are two frame vertical plates 103, each located at one end of a connecting rod 102. The drain ports 104 are located on the front and back of the frame vertical plates 103.

[0053] The drive mechanism 200 includes a water tank 201, a water pumping pipe 203, a drain pipe 206 connected to the water tank 201, and a water pump 207b. The water pump 207b is positioned below the frame cross plate 101, and the water tank 201 is positioned above the frame cross plate 101. The water pump 207b is connected to the water tank 201.

[0054] The cleaning mechanism 300 includes a connecting component 301, an adjusting component 302 communicating with the connecting component 301, a pressure component 303 disposed below the adjusting component 302, and a rotating component 304, wherein the connecting component 301 is connected to the driving mechanism 200, and the rotating component 304 is disposed within the pressure component 303.

[0055] Furthermore: the two ends of the frame horizontal plate 101 are fixedly connected to the opposite ends of the two connecting rods 102, and the opposite ends of the two connecting rods 102 are fixedly connected to the opposite ends of the two frame vertical plates 103. Several drain ports 104 are provided on the front and back of the two frame vertical plates 103. Several drain ports 104 located at the front of one side are controlled by the same regulating valve 105, and several drain ports 104 located at the rear of one side are controlled by the same regulating valve 105.

[0056] Because it is equipped with a sliding sleeve 302a, a piston plate 302c, and a through hole 302d, when liquid rapidly flows into the sliding sleeve 302a, the pressure inside the sliding sleeve 302a will rise rapidly. Due to the small size of the support in the through hole 302d, the pressure will accumulate rapidly inside the sliding sleeve 302a. At this time, the piston plate 302c will move downward under the pressure, thereby squeezing the sliding rod 302b and the cleaning plate 307a to fit against the photovoltaic panel. This allows the device to clean photovoltaic panels of different heights, thus improving the applicability of the device.

[0057] A filter plate 202 is fixedly connected inside the water tank 201. A water suction pipe 203 is provided on the back of the water tank 201. The water tank 201 is connected to the top end of a telescopic pipe 204 through the water suction pipe 203. The bottom end of the telescopic pipe 204 is connected to the top end of a connector 205. The water suction pipe 203 is located above the filter plate 202. A drain pipe 206 is fixedly connected to the back of the water tank 201. The drain pipe 206 is located below the water tank 201. The water tank 201 is fixedly connected to the top of the frame cross plate 101. The other end of 6 is connected to the water pump assembly 207. The drain port of the water pump assembly 207 is connected to the flow guide assembly 208. The water pump assembly 207 is fixedly connected to the bottom of the frame horizontal plate 101. The water pump assembly 207 includes a mounting bracket 207a. A water pump 207b is fixedly connected inside the mounting bracket 207a. The inlet of the water pump 207b is connected to the drain pipe 206. The drain port of the water pump 207b is connected to the flow guide assembly 208. The mounting bracket 207a is fixedly connected to the bottom of the frame horizontal plate 101.

[0058] In this embodiment, by setting up a driving mechanism 200 and a cleaning mechanism 300, the photovoltaic panel is wiped. At the same time, the liquid flows along the drain assembly 308 connected to the surface of the sleeve 304a to the bottom of the cleaning plate 307a. This allows the device to spray liquid onto the photovoltaic panel while wiping it, thereby improving the cleaning effect of the device on the photovoltaic panel and avoiding incomplete cleaning due to dust adhering too firmly to the surface of the photovoltaic panel. This improves the cleaning efficiency of the device on the photovoltaic panel.

[0059] Example 2

[0060] Combined with appendix Figure 2 and attached Figure 4It is concluded that: the flow guiding component 208 includes a first conduit 208a, one end of which is connected to a four-way connector 208b. Both ends of the four-way connector 208b are connected to two second conduits 208c, and each of the two second conduits 208c is equipped with a first control valve 208d. One end of the back of the four-way connector 208b is connected to a branch pipe 208f via a second control valve 208e. The left and right ends of the branch pipe 208f are connected to two third conduits 208g, and the other ends of the two third conduits 208g are connected to two frame vertical plates 103. One end of the first conduit 208a is connected to the drain outlet of the water pump 207b. One end of the connecting component 301 is connected to the adjusting component 302, which adjusts... The bottom end of component 302 is located inside pressure component 303. Rotating component 304 is sleeved inside pressure component 303. A transmission fan blade 305 is fixedly connected to the top end of rotating component 304. A drive gear 306 is fixedly connected to the outside of rotating component 304. The bottom end of rotating component 304 is connected to cleaning component 307. A drain component 308 is fixedly connected to the outside of rotating component 304. Rotating component 304 is connected to cleaning component 307 through drain component 308. A wind component 309 is externally connected to drive gear 306. Wind component 309 is snapped under frame horizontal plate 101. Adjusting component 302 is fixedly connected inside frame horizontal plate 101. One end of connecting component 301 is connected to second conduit 208c.

[0061] The connecting assembly 301 includes a tee 301a, one end of which is connected to a connecting pipe 301b, the other end of which is connected to an elbow 301c, and the other end of the tee 301a is connected to a second conduit 208c. The other end of the elbow 301c is connected to an adjusting assembly 302. The adjusting assembly 302 includes a sliding sleeve 302a, a sealing ring 3010 fixedly connected to the outside of the sliding sleeve 302a, a sliding rod 302b slidably connected inside the sliding sleeve 302a, and a piston plate 302c fixedly connected to the top end of the sliding rod 302b. The top of both the piston plate 302c and the slide rod 302b has several through holes 302d. The upper part of the piston plate 302c is fixedly connected to the spring 302e. The top of the spring 302e is fixedly connected to the upper part of the inner wall of the slide sleeve 302a. The bottom end of the slide rod 302b is connected to the drain cover 302f. The drain cover 302f is located inside the pressure assembly 303. The upper part of the slide sleeve 302a is connected to the corresponding end of the elbow 301c. The slide sleeve 302a is fixedly connected inside the frame crossbar. The lower part of the slide sleeve 302a is fixedly connected to the telescopic bracket 3011.

[0062] In this embodiment: When the water pump 207b is running, it draws liquid from the water below through the suction pipe 203 and the telescopic pipe 204, filters it through the water tank 201, and discharges it into the first conduit 208a. When the forward button is pressed, the second control valve 208e opens simultaneously. At this time, the liquid is discharged into the frame vertical plate 103 along the first conduit 208a, the four-way valve 208b, and the third conduit 208g, and discharged through several drainage ports 104 at the rear. Due to the reaction force when the liquid is discharged, the device moves forward slowly, allowing the device to quickly adjust its position. In use, the device can be controlled simply by turning on the water pump 207b and activating the forward or backward button, which greatly reduces the difficulty of using the device.

[0063] Example 3

[0064] Combined with appendix Figure 5 and attached Figure 6 It is concluded that: the pressure component 303 includes a sealing shell 303a, a first bearing 303b is snapped into the sealing shell 303a, the upper part of the sealing shell 303a is fixedly connected to the bottom end of the telescopic bracket 3011, the sealing shell 303a is fixedly connected to the outside of the slide rod 302b, the rotating component 304 is sleeved in the first bearing 303b, the rotating component 304 includes a sleeve 304a, a plurality of liquid inlet holes 304b are opened on the outside of the sleeve 304a, the liquid inlet holes 304b are located inside the sealing shell 303a, the sleeve 304a is opened in the outside of the sleeve 304a, the transmission fan blade 305 is fixedly connected to the top end of the sleeve 304a, the drive gear 306 is fixedly connected to the outside of the sleeve 304a, the drain component 308 is sleeved in the connecting groove 304c, and the bottom end of the sleeve 304a is fixedly connected to the cleaning component 307;

[0065] Because the diameter of the driving gear 306 is larger than that of the driven gear 309c, the transmission gear will still be in a high-speed rotation state when the driving gear 306 rotates at low speed, thus ensuring the rotation speed of the exhaust fan blade 309e and the drying effect on the photovoltaic panel.

[0066] The cleaning assembly 307 includes a cleaning plate 307a, a cleaning groove 307b below the cleaning plate 307a, and a sealing sleeve 307c below the cleaning plate 307a. The cleaning plate 307a is fixedly connected to the bottom end of the sleeve 304a. The cleaning plate 307a is connected to the drainage assembly 308, which includes a connecting sleeve 308a. Several guide tubes 308b are fixedly connected to the outside of the connecting sleeve 308a, and the other ends of the guide tubes 308b are all connected to the connecting shell 308c. The sleeve 308a is fitted into the connecting groove 304c. The drain shell is connected to the cleaning plate 307a. The wind power component 309 includes a second bearing 309a. A rotating shaft 309b is fitted inside the second bearing 309a. A driven gear 309c is fixedly connected to the bottom end of the rotating shaft 309b. The driven gear 309c is fixedly connected to the exhaust fan blade 309e below through the connecting shaft 309d. The second bearing 309a is snapped into the bottom of the frame cross plate 101. The driven gear 309c is connected to the driving gear 306 for transmission.

[0067] In this embodiment: when the sleeve 304a rotates synchronously with the rotation of the transmission fan blade 305, it can drive the cleaning plate 307a to clean the photovoltaic panel. On the other hand, it can drive the driven gear 309c to rotate through the drive gear 306, so that the driven gear 309c drives the exhaust fan blade 309e to rotate rapidly through the connecting shaft 309d. At this time, the exhaust fan blade 309e will accelerate the air flow rate on the surface of the photovoltaic panel and the cleaning plate 307a, thereby accelerating the evaporation efficiency of the residual liquid on the surface of the photovoltaic panel and avoiding the adsorption of dust on the photovoltaic panel due to liquid adhesion, thus ensuring the cleaning effect of the device on the photovoltaic panel.

[0068] The working principle of this invention is as follows: When using this device, the docking slots set on both sides below the frame vertical plate 103 need to be docked and installed with the external underwater track mechanism. After installation, the water pump 207b, the first control valve 208d, the second control valve 208e and the regulating valve 105 can be controlled by the external signal controller.

[0069] When the position of the device needs to be adjusted, simply start the water pump 207b via the external signal controller and press the forward button. At this time, the control valve will close several drain ports 104 at the front and open several drain ports 104 at the rear. As the water pump 207b is running, it will draw liquid from the water below through the suction pipe 203 and the telescopic pipe 204, filter it through the water tank 201, and discharge it into the first conduit 208a. When the forward button is pressed, the second control valve 208e will open simultaneously. At this time, the liquid will be discharged into the frame vertical plate 103 along the first conduit 208a, the four-way valve 208b, and the third conduit 208g, and discharged along the several drain ports 104 opened at the rear. Due to the reaction force when the liquid is discharged, the entire device moves forward slowly.

[0070] When cleaning the photovoltaic panel is required, the stop button and the forward button should be pressed, and the cleaning button should be pressed. At this time, the second control valve 208e will close, and the liquid will flow along the second conduit 208c and the first control valve 208d on both sides. When the liquid flows along the first conduit 208a, it will be injected into the four connecting pipes 301b and the sliding sleeve 302a respectively. At this time, the pressure in the sliding sleeve 302a will rise rapidly, and some liquid will enter the sealing shell 303a along the lower sliding rod 302b and the through hole 302d opened above the piston plate 302c. Then, it will be discharged along the liquid inlet hole 304b on the surface of the sleeve 304a to the bottom of the cleaning plate 307a. When liquid enters the sealing shell 303a, it will contact the drive fan blade 305. As the liquid flows, the friction and pressure will synchronously drive the drive fan blade 305, the sleeve 304a and the cleaning plate 307a to rotate, thereby achieving the effect of wiping the photovoltaic panel.

[0071] When the sleeve 304a rotates synchronously with the rotation of the drive fan blade 305, it can drive the cleaning plate 307a to clean the photovoltaic panel. On the other hand, it can drive the driven gear 309c to rotate through the drive gear 306, so that the driven gear 309c drives the exhaust fan blade 309e to rotate rapidly through the connecting shaft 309d. At this time, the exhaust fan blade 309e will accelerate the air flow rate on the surface of the photovoltaic panel and the cleaning plate 307a, thereby accelerating the evaporation efficiency of the residual liquid on the surface of the photovoltaic panel.

[0072] When liquid rushes into the sliding sleeve 302a, the pressure inside the sliding sleeve 302a will rise rapidly. Due to the small size of the through hole 302d support, the pressure will accumulate rapidly inside the sliding sleeve 302a. At this time, the piston plate 302c will move downward under the pressure, thereby squeezing the sliding rod 302b and the cleaning plate 307a to fit with the photovoltaic panel through the piston plate 302c.
