The photovoltaic matrix is ​​composed of multiple photovoltaic panels spliced ​​together, and the surface of the photovoltaic matrix is ​​rectangular.

[0003] Since the photovoltaic matrix is ​​exposed to the natural environment for a long time, dust or debris will accumulate on the surface after long-term use, so a photovoltaic cleaning robot is usually configured to regularly clean the surface of the photovoltaic matrix.

[0004] However, the existing photovoltaic cleaning robots use a large-span frame to adapt to the width of the photovoltaic matrix. The frame is spliced ​​with bolts, which has a complicated process and poor assembly accuracy. In addition, the frame integrates a motor, a transmission mechanism, and a cleaning mechanism. The overall weight of the frame is heavy. During long-term use, the connection may become loose due to vibration, which may seriously affect the normal operation of the photovoltaic cleaning robot.

[0053] Embodiment 1

[0054] See also Figure 1 and Figure 2 , this embodiment provides a frame structure 100 for a photovoltaic cleaning machine, hereinafter collectively referred to as the frame structure 100 .

[0055] In this embodiment, the frame structure 100 includes a beam frame 110, and both ends of the beam frame 110 in the length direction L are provided with a first mounting vertical plate 120, that is, two first mounting vertical plates 120 are provided. The middle part of the beam frame 110 may be provided with a second mounting vertical plate 130 according to design requirements. Of course, if the installation requirements of the roller brush device are met, the second mounting vertical plate may not be provided. This embodiment is described by taking the example of providing a second mounting vertical plate 130 in the middle part of the beam frame 110.

[0056] In some embodiments, two, three or other numbers of the second mounting vertical plates 130 may be provided according to the length of the beam frame 110. It should be understood that the above is only an example and is not intended to limit the scope of protection of the present application.

[0057] Furthermore, the beam frame 110, the first mounting vertical plate 120 and the second mounting vertical plate 130 are welded together. The first mounting vertical plates 120 have first mounting holes 121 for mounting the drive device 300 on opposite sides, and the second mounting vertical plates 130 have second mounting holes 131 for mounting the bearing seat.

[0058] It can be understood that in this embodiment, the frame 110, the first mounting plate 120 and the second mounting plate 130 are welded into an integral frame structure 100, so that the integrity of the frame structure 100 is improved. In addition, the first mounting plate 120 and the second mounting plate 130 are reserved for mounting holes for the drive device 300 and the bearing seat (the corresponding first mounting hole 121 and the second mounting hole 131), which can realize the modular assembly of the drive device 300 and the roller brush device 400 in the photovoltaic cleaning machine, simplify the installation structure and assembly process, and greatly reduce the manufacturing and assembly costs. At the same time, the use of welding connection and modular assembly can also reduce the weight of the whole machine and realize lightweight design. Since there is no problem of loose connection, the structure is more reliable.

[0059] In order to more clearly describe the technical solution of the present application, the rack structure 100 provided in this embodiment is described in detail below:

[0060] Please also read Figure 3 , Figure 4 and Figure 5 The first mounting vertical plate 120 is provided with a first positioning convex plate 122 at the top, and a first positioning step 123 is formed between the first positioning convex plate 122 and the top of the first mounting vertical plate 120. The first positioning convex plate 122 is clamped in the beam frame 110 and is welded and fixed to the inner peripheral wall of the beam frame 110, and the first positioning step 123 is abutted against the bottom surface of the beam frame 110 and is welded and fixed.

[0061] It can be understood that when welding the first mounting vertical plate 120, the first positioning protrusion 122 can be first inserted into the beam frame 110, and the first positioning step 123 can be abutted against the bottom surface of the beam frame 110. In this way, the first mounting vertical plate 120 can be initially positioned for welding to facilitate subsequent welding and ensure welding accuracy and quality.

[0062] In this embodiment, the first vertical mounting plate 120 and the first positioning protruding plate 122 are integrally formed structures, such as by bending or stamping.

[0063] In some embodiments, the first vertical mounting plate 120 and the first positioning protruding plate 122 may also be welded into an integral structure.

[0064] Furthermore, the inner peripheral wall of the beam frame 110 includes two end wall surfaces located in the length direction L and two side wall surfaces 1110 located in the width direction W.

[0065] In this embodiment, the first positioning protrusion 122 is an "L"-shaped bent plate, and the first positioning protrusion 122 has a vertical plate portion 1220 and a horizontal plate portion 1221 that are connected as one body (for example, bent or welded as one body), the vertical plate portion 1220 is connected to the top of the first mounting vertical plate 120, and the horizontal plate portion 1221 is located on the side of the vertical plate portion 1220 away from the first mounting vertical plate 120.

[0066] The two ends of the vertical plate portion 1220 and the two ends of the horizontal plate portion 1221 are respectively abutted against the two side wall surfaces 1110 and fixed by welding, and the long side of the horizontal plate portion 1221 is abutted against the corresponding end wall surfaces and fixed by welding.

[0067] It can be understood that the vertical plate portion 1220 and the horizontal plate portion 1221 are provided on the first positioning protrusion 122. On the one hand, the contact surface with the beam frame 110 can be increased to improve the reliability of positioning; on the other hand, the welding area is increased to improve the stability after welding. On the other hand, the strength of the crossbeam at the end of the beam frame 110 (i.e., the first crossbeam 112 described below) can be strengthened by welding the vertical plate portion 1220 and the cross plate portion 1221 to the beam frame 110, thereby improving the structural strength and stability of the frame structure 100.

[0068] Furthermore, at least one first through hole 1222 is provided on the vertical plate portion 1220, and a hollow hole 1230 is provided on the first positioning step 123. It can be understood that the provision of the first through hole 1222 and the hollow hole 1230 can facilitate the passage of the wire harness and the installation of the detection element on the one hand, and can save materials and reduce the weight of the first mounting vertical plate 120 on the other hand, so as to realize the lightweight design of the frame structure 100.

[0069] Furthermore, the first mounting vertical plates 120 at both ends of the beam frame 110 are provided with avoidance grooves 124 for avoiding the driving device 300 on opposite sides. The avoidance grooves 124 are formed by bending the first mounting vertical plates 120 and are used to accommodate the motor shaft and the mechanical transmission mechanism in the driving device 300. The mechanical transmission mechanism can be a pulley transmission mechanism, a gear transmission mechanism or a sprocket transmission mechanism.

[0070] It should be noted that in the prior art, the driving device 300 is designed with necessary protection in order to ensure the connection strength with the frame structure 100, that is, it is equipped with a box and an inspection hatch, which not only increases the design difficulty, but also makes the entire photovoltaic cleaning machine heavy at both ends and light in the middle, increasing the risk of cracks at the edge of the photovoltaic panel. In this embodiment, a avoidance groove 124 is set on the first mounting vertical plate 120 to accommodate the motor shaft and mechanical transmission mechanism in the driving device 300, and the side of the first mounting plate facing away from the second mounting plate is a whole plate structure. Therefore, after the driving device 300 is installed, the avoidance groove 124 can provide protection for the motor shaft and the mechanical transmission mechanism (equivalent to the box specially configured for the driving device 300 in the prior art), preventing rainwater, dust and debris from entering and affecting the normal operation of the driving device 300. In this way, in this embodiment, the setting of the avoidance groove 124 in the first mounting vertical plate 120 reduces the weight of the photovoltaic cleaning machine at both ends, thereby reducing the impact of the photovoltaic cleaning machine on the edge of the photovoltaic panel.

[0071] See also Figure 2 , Figure 6 and Figure 7 A second positioning convex plate 132 is provided on the top of the second mounting vertical plate 130, and a second positioning step 133 is formed between the second positioning convex plate 132 and the top of the second mounting vertical plate 130. The second positioning convex plate 132 is clamped in the beam frame 110 and is welded and fixed to the two side wall surfaces 1110 of the beam frame 110 in the width direction W, and the second positioning step 133 is abutted against the bottom surface of the beam frame 110 and is welded and fixed.

[0072] It is understandable that when welding the second mounting vertical plate 130, the second positioning convex plate 132 can be first inserted into the beam frame 110, and the second positioning step 133 can be abutted against the bottom surface of the beam frame 110, so that the second mounting vertical plate 130 can be initially positioned for welding, so as to facilitate subsequent welding and ensure welding accuracy and welding quality. Furthermore, the provision of the second positioning convex plate 132 and the second positioning step 133 can increase or decrease the contact area between the second mounting vertical plate 130 and the beam frame 110, increase the welding area, and improve the stability of the second mounting vertical plate 130 after welding. On the other hand, the welding of the second positioning convex plate 132 and the beam frame 110 can strengthen the auxiliary support function of the beam frame 110, thereby improving the structural strength and stability of the frame structure 100.

[0073] In some embodiments, the second positioning lug 132 can also be designed in an "L" shape, which can increase the structural strength and bending resistance of the second positioning lug 132 and enlarge the welding area.

[0074] In this embodiment, the second mounting vertical plate 130 and the second positioning lug 132 are of an integrally formed structure, such as bending forming or stamping forming.

[0075] In some embodiments, the second mounting vertical plate 130 and the second positioning lug 132 can also be welded into an integral structure.

[0076] At least one second through hole 1320 is provided on the second positioning lug 132, and a third through hole 1330 is provided on the step surface of the second positioning step 133. It can be understood that the arrangement of the second through hole 1320 and the third through hole 1330 can facilitate the passing of the wire harness and the installation of the detection element on the one hand, and can save materials and reduce the weight of the first mounting vertical plate 120 on the other hand, so as to realize the lightweight design of the frame structure 100.

[0077] Please refer to Figure 1 、 Figure 5 and Figure 7 , the above beam frame 110 includes two longitudinals 111 arranged in parallel, two first cross beams 112 arranged in parallel, and at least one second cross beam 113. The end parts of the two longitudinals 111 are respectively connected to the corresponding first cross beams 112. At least one second cross beam 113 is arranged on the beam frame 110 along the length direction L, and the two ends of each second cross beam 113 are respectively connected to the corresponding longitudinal 111. The first cross beam 112 is welded and connected to the corresponding first mounting vertical plate 120. The mounting structure of the first mounting vertical plate 120 has been introduced above and will not be elaborated here.

[0078] In this embodiment, the longitudinal 111 and the first cross beam 112 are of a hollow tube structure, the second cross beam 113 is a "冂"-shaped bent plate, and at least one fourth through hole 1130 is provided on the second cross beam 113. In this way, on the one hand, the weight of the entire beam frame 110 can be reduced, and the overall structural strength of the beam frame 110 can be increased through the second cross beam 113; on the other hand, the "冂"-shaped second cross beam 113 has better anti-bending ability and mechanical strength; on the third hand, the fourth through hole 1130 on the second cross beam 113 can facilitate the passing of the wire harness and the installation of the detection element.

[0079] Furthermore, the above longitudinal 111, first cross beam 112 and second cross beam 113 are fixed by welding to ensure better stability of the entire frame structure 100.

[0080] Embodiment 2

[0081] Please refer to Figures 1 to 9, this embodiment provides a photovoltaic cleaning machine. The photovoltaic cleaning machine applies the frame structure 100 provided in the first embodiment above.

[0082] The photovoltaic cleaning machine further includes an electric control box 200, a driving device 300, and a rolling brush device 400. Among them, the electric control box 200 is placed on the top of the beam frame 110, the driving devices 300 are arranged on both first mounting vertical plates 120, and a rolling brush device 400传动连接的滚刷装置400 is arranged between each first mounting vertical plate 120 and the second mounting vertical plate 130. That is to say, each driving device 300 drives the corresponding rolling brush device 400 to perform cleaning operations. It should be noted that the driving device 300 is also used to drive the photovoltaic cleaning machine to walk on the photovoltaic panel to be cleaned.

[0083] Please refer to Figure 1 and Figure 2 , further, the photovoltaic cleaning machine further includes a photovoltaic cover plate 500, and the photovoltaic cover plate 500 is arranged on the top surface of the beam frame 110. Among them, the long sides of the photovoltaic cover plate 500 are fixed on the beam frame 110 through clamping components 600.

[0084] It should be noted that the brush in the rolling brush device 400 is generally made of plastic. Prolonged exposure to sunlight and rain immersion will accelerate the aging of the brush. Thus, in the prior art, a cover plate is provided on the top of the beam frame 110 to shield the brush, and at the same time, a solar photovoltaic panel is laid on the cover plate, which increases the weight of the robot and is not conducive to lightweight design. In this embodiment, the photovoltaic cover plate 500 is used to replace the top cover plate of the entire photovoltaic cleaning machine. On the one hand, the photovoltaic cover plate 500 can supply power to the photovoltaic cleaning machine; on the other hand, it can solve the problem of the cover plate blocking sunlight, rain, and sundries to prevent the aging of the rolling brush device 400 and internal components; on the other hand, reducing the cover plate components can reduce the weight of the whole machine.

[0085] It should also be noted that the above photovoltaic cover plate 500 can be one or more. Further, in order to improve the clamping stability of the photovoltaic cover plate 500, multiple clamping components 600 can be arranged at intervals along the long sides of each photovoltaic cover plate 500 for clamping.

[0086] Please refer to Figure 8 and Fig. 9 , the above clamping component 600 includes a clamping block body 610 and a clamping adjustment member 620. Among them, the clamping block body 610 is in a "冂" shape. Named in its use state, the "冂" - shaped clamping block body 610 includes an upper clamping plate 611, a connecting plate 612, and a lower clamping plate 613 that are connected as a whole, and the clamping adjustment member 620 is arranged on the lower clamping plate 613.

[0087] It should be noted that the part "传动连接的滚刷装置400" in the original text seems to be incomplete or incorrect in expression. I have translated it as best as possible according to the context. If there are any inaccuracies, please adjust according to the correct content.When in use, the upper clamping plate 611 contacts the upper surface of the photovoltaic cover plate 500, and the lower clamping plate 613 is located at the bottom of the longitudinal beam 111 of the beam frame 110, that is, the photovoltaic cover plate 500 and the longitudinal beam 111 are located between the upper clamping plate 611 and the lower clamping plate 613. The clamping adjustment member 620 is used to adjust the clamping force of the clamping assembly 600 on the photovoltaic cover plate 500 and the longitudinal beam 111.

[0088] Furthermore, the clamping adjustment member 620 can be selected as a bolt, which passes through the lower clamping plate 613 and abuts against the longitudinal beam 111. The bolt and the lower clamping plate 613 are threaded. The bottom of the longitudinal beam 111 is provided with a positioning hole for positioning the bolt. In this way, the photovoltaic cover 500 can be clamped and positioned, and the clamping assembly 600 can be prevented from loosening and deviating, thereby ensuring the fitting and pressing effect between the photovoltaic cover 500 and the longitudinal beam 111.
