[0002] With the increasing public awareness of environmental protection and the rapid popularization of photovoltaic power generation technology, more and more households, enterprises, and power plants have begun to lay power generation systems based on photovoltaic panels. Photovoltaic panels are generally laid on the tops of urban buildings or in desert areas with good sunshine conditions. The surface is easily covered with dirt such as dust, fallen leaves, bird droppings or stains. If the dirt cannot be cleaned up in time, the power generation efficiency of the photovoltaic panels will drop sharply. Therefore, in order to improve the power generation efficiency of solar panels, cleaning robots are generally placed on photovoltaic panels, and the dirt on the photovoltaic panels is cleaned according to a certain time frequency and a predetermined walking trajectory.

[0003] Existing cleaning robots used for cleaning photovoltaic panels often adopt a horizontal design, and their cleaning methods mainly include dry cleaning and wet cleaning.

[0004] For dry cleaning, if the photovoltaic panel is severely contaminated or the stains are highly adherent, the horizontal cleaning robot cannot clean such dirt.

[0005] Most wet cleaning methods use spraying, brushing, scraping, etc. to effectively clean the photovoltaic panels, and have a good cleaning effect on difficult-to-clean dirt such as bird droppings. However, for wiping dust, such as the cleaning robot described in invention patent CN110681622B, the belt rag 11 can only wipe the photovoltaic panel in a linear motion back and forth, which can easily cause secondary pollution to the surrounding photovoltaic panels that have been cleaned.

[0006] In addition, most of the existing horizontal cleaning robots are not equipped with a secondary water circulation system, and the secondary wastewater generated by the cleaning of photovoltaic panels is not fully utilized, thus causing a certain amount of water resource waste and being not environmentally friendly.

[0026] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figures 1 to 4As shown, this embodiment provides a horizontal cleaning robot, including a cleaning mechanism 1 and a walking mechanism 2 for driving the cleaning mechanism 1 to move along a cleaning surface, the cleaning mechanism 1 includes a rag that can rotate back and forth and a cloth washing assembly 12 for washing the rag, the rag elastically abuts against the cleaning surface and rotates in one direction to clean the dirt on the cleaning surface, and in each reciprocating rotation cycle of the rag, the cloth washing assembly 12 cleans the dirty part of the rag that has been in contact with the cleaning surface.

[0028] In this embodiment, the cleaning surface is the surface of the photovoltaic panel, and the dirt on the cleaning surface includes dust, fallen leaves, bird droppings or stains.

[0029] The cleaning mechanism 1 also includes the driving assembly, which includes a driver 131, a driving wheel 132 and a driven wheel 133 that cooperates with the driving wheel 132. Specifically, the driver 131 is a motor, and the driving shaft of the motor is connected to the driving wheel 132 through a belt drive to drive the driving wheel 132 to rotate.

[0030] The specific rag is a belt rag 11, and the belt rag 11 is arranged between the driving wheel 132 and the driven wheel 133 to form a transmission connection, thereby ensuring that the belt rag 11 reciprocates in one direction, and the belt rag 11 will not cause damage to the photovoltaic panel while cleaning the photovoltaic panel.

[0031] The rag is elastically abutted against the cleaning surface and rotated in one direction to effectively clean the dirt on the cleaning surface. In each reciprocating rotation cycle of the rag, the dirty part of the rag that has been in contact with the cleaning surface is cleaned by the cloth washing component 12 to avoid the contaminated rag from contacting the cleaning surface again, so as to avoid secondary contamination of the surrounding cleaning surface that has been cleaned, thereby ensuring the cleaning effect.

[0032] Of course, in other embodiments, the rag can also be divided into multiple independent parts, and the multiple independent parts are arranged at intervals and attached to the outside of the conveyor belt between the driving wheel 132 and the driven wheel 133 in sequence. This can also avoid secondary contamination of the surrounding cleaning surface that has been cleaned.

[0033] In another preferred embodiment, Figure 2 As shown, the belt rag 11 is equipped with an elastically retractable roller unit 14, and the roller surface of the roller unit 14 can elastically retract to abut the inner side of the belt rag 11 to drive the outer side of the belt rag 11 to abut against the cleaning surface and apply pressure to the cleaning surface in the direction of the cleaning surface. The elastic retractability of the roller unit 14 can realize adaptive adjustment of the pressure, thereby realizing close contact between the belt rag 11 and the cleaning surface, so as to ensure effective cleaning of the dirt on the cleaning surface.

[0034] More specifically, the cleaning mechanism 1 and the walking mechanism 2 are both mounted on a frame 3, the roller unit 14 is provided with a mounting frame 15, the roller unit 14 is rotatably mounted on the mounting frame 15, the frame 3 is provided with a guide member 32 for cooperating with the mounting frame 15 to rise and fall, an elastic connecting member 16 is provided between the mounting frame 15 and the frame 3, so that the roller unit 14 forms an elastically retractable arrangement, and as Figure 3 The mounting frame 15 shown is restricted by the guide member 32 so that the mounting frame 15 can be raised or lowered along the restricted direction of the guide member 32 .

[0035] During specific implementation, there are multiple elastic connectors 16 , and the specific elastic connector 16 is a spring, the upper end of the spring is connected to the bottom of the frame 3 , and the lower end of the spring is connected to the top of the mounting frame 15 .

[0036] The roller unit 14 includes a plurality of rollers, which are installed in sequence at intervals at the bottom of the mounting frame 15 and can freely rotate in a circumferential direction on the mounting frame 15 to ensure that they move together with the belt rag 11 .

[0037] like Figure 3 As shown, there are multiple guide members 32, and the multiple guide members 32 are respectively fixedly installed on the four sides of the mounting frame 15. The mounting frame 15 has a guide column that cooperates with the guide member 32. The guide column can be raised and lowered and inserted into the guide groove of the guide member 32 so that the guide column is restricted by the guide groove of the guide member 32, thereby ensuring that the guide column of the mounting frame 15 can only move up and down in the guide groove of the guide member 32, thereby ensuring that the roller unit 14 assembled on the mounting frame 15 will not be accidentally offset or misplaced when rolling on the cleaning surface, thereby ensuring that the belt rag 11 will not cause additional damage or scratches to the photovoltaic panel.

[0038] In addition, the frame 3 is equipped with a rotating bolt 151, which passes through the frame 3 and forms a threaded connection with the frame 3. Then, the rotating bolt 151 passes through the end of the frame 3 and is fixed on the mounting frame 15.

[0039] By rotating the bolt 151, the mounting frame 15 is driven to rise or fall, that is, the roller mounted on the mounting frame 15 is driven to move upward or downward, thereby adjusting the pressure between the roller unit 14, the belt rag 11 and the photovoltaic panel, so as to be suitable for cleaning dirt on photovoltaic panels with different degrees of pollution.

[0040] Further preferably, Figure 2As shown, the belt rag 11 is equipped with a matching tensioning roller 17 and a guide roller 18. The tensioning roller 17 is used to adjust the tightness of the belt rag 11, and the guide roller 18 is used to guide and squeeze the belt rag 11, so as to ensure the transmission effect of the belt rag 11 and squeeze out the water contained in the belt rag 11 to further clean and squeeze the belt rag 11.

[0041] In another preferred embodiment, Figure 2 The cloth washing assembly 12 shown includes a water tank 121, a shower head 122, and a diaphragm pump 123 installed between the water tank 121 and the shower head 122. The water outlet of the water tank 121 is connected to the water inlet of the diaphragm pump 123 through a water pipe, and the water outlet of the diaphragm pump 123 is connected to the water inlet of the shower head 122 through a water pipe.

[0042] The shower head 122 is suspended above the belt rag 11, and the water spraying direction of the shower head 122 is toward the dirty part of the belt rag 11, so that the water sprayed from the shower head 122 is sprayed toward the dirty part of the belt rag 11, so as to effectively remove the dirt stained on the belt rag 11, thereby ensuring that the part of the belt rag 11 that has been cleaned again is rotated toward the cleaning surface again, and the cleaning surface is repeatedly cleaned with the clean part of the belt rag 11.

[0043] In this specific embodiment, a water level sensor for sensing the water level is disposed in the water tank 121 to ensure that the water in the water tank 121 does not overflow.

[0044] The water in the water tank 121 is pumped to the water inlet of the shower head 122 through the water outlet of the water tank 121 by the diaphragm pump 123, so that the shower head 122 can spray and clean the dirty parts of the belt rag 11 that have come into contact with the cleaning surface.

[0045] In another preferred embodiment, a filter 124 for filtering dirty water is provided between the shower head 122 and the diaphragm pump 123. The water sprayed from the shower head 122 flows back to the water inlet of the water tank 121 through a reflux groove 31. Specifically, the reflux groove 31 is connected to the water inlet of the water tank 121, that is, the reflux groove 31 and the water tank 121 together form an integrally formed water collecting box to ensure that all the water sprayed from the shower head 122 falls into the reflux groove 31.

[0046] In this embodiment, the water outlet of the water tank 121 is equipped with a quick connector that is easy to install, so that the water pipe connected to the diaphragm pump 123 can be quickly installed on the quick connector at the water inlet of the water tank 121.

[0047] The reflux groove 31 is connected to the water tank 121 so that the reflux groove 31, the water tank 121, the diaphragm pump 123, the filter 124 and the shower head 122 together form a complete secondary water circulation system to ensure the repeated use of water resources and meet environmental protection requirements.

[0048] like Figure 4 As shown, when the horizontal cleaning robot is cleaning the photovoltaic panel, the sewage returned from the reflux tank 31 passes through the water tank 121, the diaphragm pump 123 and the filter 124 in sequence, and is filtered and purified by the filter 124 to remove dirt in the sewage, and the filtered clean water is transported to the shower head 122 again to clean the belt rag 11, and it is recycled in this way to achieve repeated utilization of water resources.

[0049] When the capacity of the water tank 121 is large enough and has a secondary water circulation system, it can ensure that the horizontal cleaning robot of this embodiment can clean a large area of ​​photovoltaic panel sites at one time, so as to further improve work efficiency.

[0050] Of course, the water inlet of the water tank 121 can also be opened manually to replenish water from an external water source into the water tank 121 .

[0051] Further preferably, the filter 124 is a Y-type filter, and the Y-type filter is equipped with a solenoid valve for controlling the discharge of dirt formed by filtering.

[0052] The solenoid valve is opened or closed to discharge dust generated in the Y-type filter and realize self-cleaning of the Y-type filter.

[0053] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
