[0044] See attached Figure 1 and Figure 2The embodiment of the present application provides a multifunctional photovoltaic panel cleaning robot, including a mobile carrier 1, a flushing assembly 2, a cleaning assembly 3 and an automatic guiding system 4, wherein the flushing assembly 2, the cleaning assembly 3 and the automatic guiding system 4 are all arranged on the mobile carrier 1 and move with the mobile carrier 1. The automatic guiding system 4 is used to provide guidance for the mobile carrier 1, so that the cleaning robot can complete the cleaning work of the photovoltaic panel according to the planned path, the cleaning assembly 3 is used to clean the photovoltaic panel to achieve a dry cleaning effect, and the flushing assembly 2 is used to spray and flush the photovoltaic panel to achieve the purpose of water washing.

[0045] It can be understood that the multifunctional photovoltaic panel cleaning robot provided in the embodiment of the present application, by equipping the mobile carrier 1 with a flushing assembly 2, a cleaning assembly 3 and an automatic guiding system 4, uses the automatic guiding system 4 to plan the movement path of the cleaning robot, and can select a reasonable cleaning method according to the on-site conditions. For example, if the photovoltaic panel is thinly dusted, the dry cleaning mode can be selected, and the cleaning assembly 3 can be used to brush the dust; if the photovoltaic panel is thickly dusted, the cleaning work is completed by water washing. If water washing cannot flush away the dust on the photovoltaic panel, the cleaning assembly 3 can be used to complete the dust removal by combining dry cleaning and water washing, so as to reasonably allocate resources and avoid wasting resources.

[0046] Specifically:

[0047] like Figure 1 to Figure 2 As shown, the mobile vehicle 1 includes a frame, wheels and a travel motor, the travel motor is fixed on the frame, the wheels are assembled on the frame, the wheels are equipped with tracks, the travel motor is connected to the wheels by transmission, a housing is fixed on the frame to seal the components on the frame, and the mobile vehicle 1 can be driven by the travel motor to achieve smooth movement. At the same time, lighting lamps are arranged on the front and rear sides of the frame, and light strips 5 are arranged on the left and right sides of the frame to serve the purpose of warning and lighting.

[0048] Further, such as Figure 1 and Figure 2 As shown, the flushing assembly 2 includes a flushing water drain 201, which is fixed to the mobile vehicle 1 through a water drain bracket 202, and the water drain bracket 202 is fixed to the mobile vehicle 1 through bolts. The water drain bracket 202 includes a pair of bent claws, and the flushing water drain 201 is clamped into the claws and fixed by tightening bolts. A water inlet flange pipe 203 and a plurality of spray heads 204 are provided on the flushing water drain 201. The water inlet flange pipe 203 is used to connect a water pipe to provide a water source for the cleaning robot to wash the photovoltaic panels. The spray head 204 is obliquely downwardly aimed at the ground to spray water on the photovoltaic panels.

[0049] Among the above, Figures 1 to 4As shown, the cleaning assembly 3 includes a cleaning brush 301, a cleaning motor 302, a dust suction pipe 303 and a dust collection box 304. The cleaning brush 301 is fixed to the mobile vehicle 1 through a front lip frame 305. The front side frame and the vehicle frame are integrally formed. The cleaning motor 302 is fixedly mounted on the front lip frame 305, and the output end of the cleaning motor 302 passes through the front lip frame 305 downwardly through a bearing connection and is transmission-connected to the cleaning brush 301. There are multiple cleaning brushes 301. This embodiment uses two examples. Each cleaning brush 301 is equipped with a cleaning motor 302, and the rotation directions of adjacent cleaning brushes 301 are opposite, so that dust can flow backwards from between the two cleaning brushes 301. The cleaning brush 301 includes a brush seat and bristles. The brush seat is connected to the output end of the cleaning motor 302 in a key-to-keyway connection manner. The bristles are fixed on the brush seat, so that the cleaning brush 301 can be easily replaced after the bristles are used. At the same time, a dust suction pipe 303 is arranged at the back of the midpoint of the line connecting the adjacent cleaning brushes 301 and at the belly of the mobile vehicle 1, and the inlet of the dust suction pipe 303 faces the side of the cleaning brush 301, and the dust brushed by the cleaning brush 301 is sucked into the dust suction pipe 303. The dust suction pipe 303 leads to a dust collecting box 304, which is fixed to the vehicle frame. The motor assembly 10 is arranged in the dust collecting box 304, and the motor assembly 10 includes a fan for sucking dust into the dust collecting box 304.

[0050] In order to prevent the wet air from being sucked into the fan and causing a short circuit in the combination of dry cleaning and water cleaning, in a preferred embodiment, Figure 4As shown, a dust removal component 7, a water removal component 8 and a drying component 9 are also provided in the dust collection box 304. The dust removal component 7 includes a dust removal chamber 701 and a dustproof net 702. The dust removal chamber 701 is located inside the dust collection box 304, and the dust removal chamber 701 is provided with an air inlet and an air outlet. The air inlet is detachably connected to the dust suction pipe 303 by means of threads, and the air outlet is connected to the water removal component 8. The inner diameter of the dust removal chamber 701 gradually increases from the air inlet side to the air outlet side, and a plurality of dustproof nets 702 are arranged in the dust removal chamber 701 at equal intervals from the air inlet side to the air outlet side. The dustproof nets 702 can be installed in the dust removal chamber 701 by means of screw fixing, and the pores of the dust removal nets gradually increase from the air inlet side to the air outlet side. It can be found that, since the cross-sectional area of ​​the dust removal chamber 701 is small on the side facing the dust suction pipe 303, the cross-sectional area inside the dust removal chamber 701 gradually increases from the air inlet side to the air outlet side. According to the Bernoulli principle, under the action of the motor assembly 10, the air flow rate is greater towards the air inlet side of the dust removal chamber 701, so that the dust can be well sucked into the dust removal chamber 701. After the air enters the dust removal chamber 701, the inner diameter of the dust removal chamber 701 gradually increases, and the dust distributed per unit area tends to decrease, so that the dustproof net 702, which is arranged with a gradually increasing size and a gradually decreasing pore from front to back, can avoid excessive dust accumulation and the need for frequent cleaning or replacement of the dustproof net 702. Of course, since the dust suction pipe 303 is threadedly connected to the dust removal chamber 701, and the dust removal net is screwed to the dust removal chamber 701, it is convenient to replace and clean the dustproof net 702.

[0051] Further, such as Figure 4 As shown, an inner convex shoulder and an outer convex shoulder are provided on one side of the air outlet of the dust removal chamber 701.

[0052] The water removal component 8 includes a closed outer cavity, a breathable inner cavity 802 and a water tank 806, wherein the closed outer cavity is installed on the outer convex shoulder in a threaded connection manner, and a sealing ring can be used to ensure the sealed connection, and the breathable inner cavity 802 is arranged in the closed inner cavity, and is also installed on the inner convex shoulder in a threaded connection manner, and is sealed by a sealing ring. The inside of the breathable inner cavity 802 is provided with a water-absorbing material 804, and the water-absorbing material 804 can be a water-absorbing sponge. The top of the breathable inner cavity 802 is provided with a breathable hole 803, and the bottom of the breathable inner cavity 802 is provided with a drain pipe 805. The water tank 806 is arranged at the bottom of the closed outer cavity, and the drain pipe 805 is connected to the water tank 806. It can be imagined that most of the dust is removed from the air filtered by the dust removal assembly 7. After the wet air enters the breathable inner cavity 802, it contacts the water-absorbing material 804, absorbs most of the water and overflows from the top air holes 803. After the water-absorbing material 804 absorbs water, the water falls due to gravity from the drain pipe 805 at the bottom into the water tank 806 for buffering. The water tank 806 is provided with a water valve connected to the outside of the dust box 304 to discharge the sewage. Of course, the closed outer cavity and the breathable inner cavity 802 are fixed in a threaded connection, which is convenient for disassembly and assembly to facilitate the replacement of the water-absorbing material 804.

[0053] The drying component 9 further includes a guide air pipe 901, a heating coil 902 and a thermostat 903. The guide air pipe 901 is connected between the dewatering component 8 and the motor component 10 in an S shape. One end of the guide air pipe 901 extends into the sealed inner cavity and fits with the non-air-permeable hole 803 side of the air-permeable inner cavity 802. The airflow inlet 904 of the guide air pipe 901 is arranged in a direction, and the air flowing out of the air-permeable hole 803 enters the guide air pipe 901. A plurality of heating coils 902 are installed along the guide air pipe 901, and the heating coils 902 are electrically connected to the thermostat 903. It can be imagined that the water content in the air that absorbs a large amount of water through the water-absorbing material 804 is significantly reduced, and then through the guide air pipe 901 arranged in an S row, a good drying effect can be achieved, thereby preventing the air entering the motor component 10 from being mixed with water. Of course, in order to ensure the dryness of the air, a humidity sensor can be installed on the air flow outlet side of the air guide pipe 901 to detect the air humidity, thereby regulating the heating coil 902.

[0054] Of course, for convenience, an openable box cover is provided on the top of the dust box 304 to facilitate maintenance.

[0055] Based on the above content, it can be understood that when a cleaning method combining water washing and dry cleaning is adopted, the motor assembly 10 will suck the wet air mixed with dust into the dust removal chamber 701, and use the dustproof net 702 to remove the dust in the air. The wet air then enters the breathable inner cavity 802 and contacts the water-absorbing material 804. After absorbing most of the moisture, it overflows from the top into the guide air duct 901 for drying and then enters the motor assembly 10. During the whole process, the wet air cannot directly contact the motor assembly 10, thereby avoiding the motor assembly 10 from short circuiting due to contact with the wet air.

[0056] In addition, it can be understood that in order to facilitate communication and charging, the mobile vehicle 1 is equipped with an aviation plug 6 to complete the relevant communication and charging connection functions.

[0057] In summary, a multifunctional photovoltaic panel cleaning robot proposed in the embodiment of the present application includes a mobile carrier, a flushing assembly, a cleaning assembly and an automatic guiding system, which can enable the cleaning robot to complete the cleaning work of the photovoltaic panel along a preset path, and can adopt a variety of optional methods such as dry cleaning, water washing and a combination of dry and water washing to clean the photovoltaic panel. It has various functions, which can not only ensure the cleaning effect, but also adopt reasonable cleaning methods to allocate resources according to the environment to avoid waste of resources.

[0058] Finally, it should be noted that the cleaning robot in this application is not only suitable for cleaning photovoltaic panels, but can also be used in other scenarios, such as the ground, glass curtain walls, etc.

[0059] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
