[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Please refer to Figures 1-8As shown in the figure, the present invention provides a technical solution: a gantry-type adaptive photovoltaic panel cleaning device, including a cleaning mechanism 1, on which an adjusting mechanism 2 is provided. The adjusting mechanism 2 includes a servo electric cylinder 201, two chutes 202 and a double-hole plate 206. A slider 203 is slidably connected inside each chute 202. A connecting rod 204 is installed on the top of one of the sliders 203. Rectangular holes 205 are formed at the bottom of one of the sliders 203 and on one side of the other slider 203. Round rods 207 are rotatably connected inside the two through holes of the double-hole plate 206 through bearings. An electric push rod 208 is installed on the lower inclined surface of the double-hole plate 206. One end of the telescopic end of the electric push rod 208 is installed with a rectangular plate 209. A baffle 210 is fixed on the lower inclined surface of the rectangular plate 209. Two symmetrically arranged mounting blocks 211 are fixed on the surface of the double-hole plate 206. A laser distance sensor 212 is installed on the surface of each mounting block 211. One end of the telescopic end of the servo electric cylinder 201 is installed with the top of the connecting rod 204. The connecting rod 204 is inside one of the chutes 202. The two round rods 207 are respectively fixed inside the two rectangular holes 205. The laser emission ends of the two laser distance sensors 212 respectively penetrate through the surface of the mounting block 211 movably. The cleaning mechanism 1 includes a bracket 101 and a cylindrical hole 112. Four universal wheels 102 are installed at the bottom of the bracket 101. A controller 111 is installed on one side of the bracket 101. The servo electric cylinder 201 is installed on the top of the bracket 101. One end of the telescopic end of the servo electric cylinder 201 penetrates through the top of the bracket 101 movably. The servo electric cylinder 201 is electrically connected to the controller 111. One of the chutes 202 is opened on one side of the inner wall of the bracket 101, and the other chute 202 is opened on the top of the inner wall of the bracket 101. The two laser distance sensors 212 are both electrically connected to the controller 111. The electric push rod 208 is electrically connected to the controller 111. The water inlet ends of the two spray heads 110 are respectively fixed and penetrate through the lower inclined surface of the rectangular plate 209. The cylindrical hole 112 is opened on the lower inclined surface of the double-hole plate 206.

[0022] In this embodiment, when it is necessary to adjust the angle of the cleaning component in the gantry-type photovoltaic panel cleaning device, first connect the controller 111 to an external power supply. Then, with the cooperation of the four universal wheels 102, move the bracket 101 to a suitable position (the photovoltaic panel to be cleaned is inside the bracket 101, and the surface of the photovoltaic panel faces the inner wall side of the bracket 101). Next, use the controller 111 to simultaneously start the servo electric cylinder 201 and the two laser distance sensors 212. At this time, the started servo electric cylinder 201 will drive one of the sliders 203 to slide inside one of the chutes 202 with the cooperation of the connecting rod 204. The sliding slider 203 will, with the cooperation of the two rectangular holes 205, two bearings, two round rods 207, and the double-hole plate 206, cause the other slider 203 to slide inside the other chute 202. At the same time, with the cooperation of the two sliding sliders 203, two rectangular holes 205, two round rods 207, and two bearings, the inclination angle of the double-hole plate 206 will be changed. At the same time, the two started laser distance sensors 212 will continuously measure the distance between their detection ends and the surface of the photovoltaic panel and transmit it to the controller 111 in the form of an electrical signal. The controller 111 will compare the distance data transmitted by the two laser distance sensors 212 received each time. When the distance data transmitted by the two laser distance sensors 212 received by the controller 111 are different, the servo electric cylinder 201 will continue to start. When the distance data transmitted by the two laser distance sensors 212 received by the controller 111 are the same, the controller 111 will directly turn off the servo electric cylinder 201, that is, the lower inclined surface of the double-hole plate 206 is parallel to the surface of the photovoltaic panel. At the same time, under the action of the electric push rod 208, the rectangular plate 209 and the baffle 210 can both complete the angle adjustment operation.

[0023] Embodiment 2: According to Figures 1-4 、 Figure 6 and Figure 8As shown in the figure, the cleaning mechanism 1 includes a bracket 101 and a cylindrical hole 112. Four universal wheels 102 are installed at the bottom of the bracket 101. A water tank 103 is installed at the top of the bracket 101. A water pump 104 is installed at the top of the bracket 101. An auxiliary block 105 is installed at a position near the top of the front surface of the bracket 101. A connecting pipe 106 is installed at the water inlet end of the water pump 104. A hose 107 is installed at the water outlet end of the water pump 104. A sealing plug 108 is provided at the water inlet end of the water tank 103. A tee pipe 109 is installed at the water outlet end of the hose 107. Sprayers 110 are installed at both water outlet ends of the tee pipe 109. A controller 111 is installed on one side of the bracket 101. The water inlet end of the connecting pipe 106 is installed with the water outlet end of the water tank 103. The hose 107 is movably sleeved inside the auxiliary block 105. The water outlet end of the hose 107 is movably sleeved inside the cylindrical hole 112. The water pump 104 is electrically connected to the controller 111. A rubber strip 3 is adhesively connected to the front surface of the baffle 210.

[0024] In this embodiment, when it is necessary to clean the surface of the photovoltaic panel, first, with the cooperation of the prepared lifting equipment, the sealing plug 108 is removed. Then, an appropriate amount of water is injected into the water tank 103. Next, the sealing plug 108 is reset to its original position. After that, with the cooperation of the controller 111 and the adjusting mechanism 2, the rubber strip 3 is moved until the lower inclined surface of the rubber strip 3 is at the same horizontal plane as the surface of the photovoltaic panel. Then, the controller 111 is used to start the water pump 104. At this time, the started water pump 104 will, with the cooperation of the connecting pipe 106, pump out the water inside the water tank 103 and transport it into the hose 107, and then into the tee pipe 109, and then be divided and transported into the two sprayers 110. Then, it is sprayed onto the surface of the photovoltaic panel in a fan shape from the water outlets of the two sprayers 110 (the water pressure of the water sprayed by the sprayers 110 is within a suitable range and will not damage the surface of the photovoltaic panel). Then, with the cooperation of the four universal wheels 102, the bracket 101 is moved. At this time, the moving bracket 101 will, with the cooperation of the adjusting mechanism 2, drive the rubber strip 3 and the two sprayers 110 to move together. Thus, with the cooperation of the two moving sprayers 110, the surface of the photovoltaic panel can be cleaned. When the lower inclined surface of the rubber strip 3 contacts the surface of the photovoltaic panel, the residual water on the surface of the photovoltaic panel can be scraped off under the action of the moving rubber strip 3, that is, the cleaning operation of the surface of the photovoltaic panel is completed.

[0025] The effects achieved by the entire mechanism and its working principle are as follows: When it is necessary to clean the surface of the photovoltaic panel, first, with the cooperation of the prepared lifting equipment, the sealing plug 108 is removed. Subsequently, an appropriate amount of water is injected into the interior of the water tank 103. Then, the sealing plug 108 is reset to its original position. After that, the controller 111 is connected to an external power supply. Then, with the cooperation of the four universal wheels 102, the bracket 101 is moved to a suitable position (the photovoltaic panel to be cleaned is inside the bracket 101, and the surface of the photovoltaic panel faces the inner wall side of the bracket 101). Next, the controller 111 is used to simultaneously start the servo electric cylinder 201 and the two laser distance sensors 212. At this time, the started servo electric cylinder 201 will drive one of the sliders 203 to slide inside one of the chutes 202 with the cooperation of the connecting rod 204. The sliding slider 203 will, with the cooperation of the two rectangular holes 205, two bearings, two round rods 207, and the double-hole plate 206, cause the other slider 203 to slide inside the other chute 202. At the same time, with the cooperation of the two sliding sliders 203, two rectangular holes 205, two round rods 207, and two bearings, the inclination angle of the double-hole plate 206 will be changed. Meanwhile, the two started laser distance sensors 212 will continuously measure the distance between their detection ends and the surface of the photovoltaic panel and transmit it to the controller 111 in the form of an electrical signal. The controller 111 will compare the distance data transmitted by the two laser distance sensors 212 received each time. When the distance data transmitted by the two laser distance sensors 212 received by the controller 111 are different, the servo electric cylinder 201 will continue to start. When the distance data transmitted by the two laser distance sensors 212 received by the controller 111 are the same, the controller 111 will directly turn off the servo electric cylinder 201, that is, the lower inclined surface of the double-hole plate 206 is parallel to the surface of the photovoltaic panel. Subsequently, the controller 111 is used to start the electric push rod 208. At this time, the started electric push rod 208 will drive the rectangular plate 209 to move. The moving rectangular plate 209 will drive the baffle 210 to move. At the same time, the moving baffle 210 will drive the rubber strip 3 to move. When the lower inclined surface of the rubber strip 3 is at the same horizontal plane as the surface of the photovoltaic panel (the lower inclined surface of the rubber strip 3 does not contact the surface of the photovoltaic panel), at this time, the controller 111 is used to first turn off the electric push rod 208 and then start the water pump 104. The turned-off electric push rod 208 will cause the rubber strip 3 to stop moving. At the same time, the started water pump 104 will, with the cooperation of the connecting pipe 106, pump out the water inside the water tank 103 and transport it into the hose 107, and then into the tee 109, and then be divided and transported into the two spray heads 110. After that, it is sprayed onto the surface of the photovoltaic panel in a fan shape from the water outlets of the two spray heads 110 (the water pressure of the water sprayed by the spray heads 110 is within a suitable range and will not damage the surface of the photovoltaic panel). Next, with the cooperation of the four universal wheels 102, the bracket 101 is moved,At this time, the moving bracket 101 will drive the rubber strip 3 and the two spray heads 110 to move together under the cooperation of the two chute grooves 202, the two sliders 203, the two rectangular holes 205, the two round rods 207, the two bearings, the double-hole plate 206, the electric push rod 208, the rectangular plate 209 and the baffle plate 210. Then, under the cooperation of the two moving spray heads 110, the surface of the photovoltaic panel can be cleaned. When the lower inclined surface of the rubber strip 3 comes into contact with the surface of the photovoltaic panel, the residual water on the surface of the photovoltaic panel can be scraped off under the action of the moving rubber strip 3, thus completing the cleaning operation of the surface of the photovoltaic panel.

[0026] Among them, the bearing is a common part in real life.

[0027] Among them, the laser emission ends of the two laser distance sensors 212 are on the same plane, and the plane where they are located is parallel to the lower inclined surface of the double-hole plate 206.

[0028] Among them, the controller 111 (PLC controller), the water pump 104, the servo electric cylinder 201, the laser distance sensor 212 and the electric push rod 208 are all prior arts, and their working principles are all public technologies. Their models can be selected according to actual situations and will not be explained in detail here.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
