[0002] With the rapid development of the solar photovoltaic industry, the cleaning of photovoltaic modules has become an important link. For areas with cold climates, sandstorms are prone to occur in winter, and the modules need to be cleaned more frequently, which causes ice and freezing on the surface of the modules, affecting the efficiency of the modules in absorbing solar energy and reducing the power generation performance of the modules. The traditional method of cleaning photovoltaic modules is usually to manually clean the modules, which is time-consuming, labor-intensive, and very costly, and the modules cannot be dried. Therefore, it is of great significance to develop an efficient, environmentally friendly, and low-cost integrated device for cleaning and drying photovoltaic modules.

[0003] In the prior art, the water outlet structure of the photovoltaic module cleaning equipment includes a water outlet pipe body, and the length of the water outlet pipe body is fixed.

[0028] Applying the technical solution of this embodiment, the cleaning device of the photovoltaic module includes a mobile vehicle 10, a mechanical arm 20 arranged on the mobile vehicle 10, a water tank 30 arranged on the mobile vehicle 10, a cleaning structure 40 and a first driving structure 50. The position of the mechanical arm 20 is adjustable. The cleaning structure 40 includes a mounting member 41 and a water outlet structure 42, the water outlet structure 42 is connected to the water tank 30, the mounting member 41 is connected to the mechanical arm 20, and the water outlet structure 42 is telescopically arranged on the mounting member 41. The first driving structure 50 cooperates with the driving of the water outlet structure 42, and the first driving structure 50 can drive the water outlet structure 42 to be telescopic. Through the above-mentioned arrangement, the mobile vehicle 10 can drive the mechanical arm 20 to move, and the mechanical arm 20 can also drive the cleaning structure 40 to move, so that it is convenient for the cleaning structure 40 to move to different positions, thereby realizing the cleaning of different positions of the photovoltaic module. The water outlet structure 42 is retractable, so that the water outlet structure 42 can adapt to photovoltaic modules of different widths, making the cleaning device more adaptable, and also making the water outlet structure 42 adjustable in length according to the width of the photovoltaic module, avoiding wasting water resources when the length of the water outlet structure 42 is greater than the width of the photovoltaic module. Therefore, the technical solution of this embodiment effectively solves the problem of poor versatility of the water outlet structure of the cleaning device in the related art.

[0029] The mounting member 41 includes a mounting plate 411 .

[0030] The robot arm 20 can adopt the robot arm in the prior art, and the length and angle can be freely adjusted.

[0031] The cleaning device of this embodiment is an integrated device for cleaning and drying photovoltaic modules.

[0032] like Figure 1 and Figure 2As shown, in this embodiment, the water outlet structure 42 includes a plurality of water outlet pipes 421, the cross-sectional areas of the plurality of water outlet pipes 421 are different, the plurality of water outlet pipes 421 are nested, and a water outlet hole 4211 is provided on the side wall of each water outlet pipe 421. Water can be discharged through the water outlet hole 4211 to achieve cleaning of the photovoltaic module. The plurality of water outlet pipes 421 are nested, so that the water outlet structure 42 can occupy less space when not in use.

[0033] like Figure 4 and Figure 5 As shown, part of the plurality of water outlet pipes 421 is disposed at a first end of the mounting plate 411 , and another part of the plurality of water outlet pipes 421 is disposed at a second end of the mounting plate 411 .

[0034] A first slide groove 4111 is provided at the first end of the mounting plate 411. An outlet pipe 421 closest to the mounting plate 411 among multiple outlet pipes 421 arranged at the first end of the mounting plate 411 can be slidably disposed in the first slide groove 4111 at one end of the outlet pipe 421 close to the mounting plate 411.

[0035] A second slide groove 4112 is provided at the second end of the mounting plate 411. An outlet pipe 421 closest to the mounting plate 411 among multiple outlet pipes 421 arranged at the second end of the mounting plate 411 can be slidably disposed in the second slide groove 4112 at one end of the outlet pipe 421 close to the mounting plate 411.

[0036] In the direction from the second end of the mounting plate 411 to the first end of the mounting plate 411, the lengths of the plurality of water outlet pipes 421 located at the first end of the mounting member 41 are successively reduced. In this way, the water outlet pipes 421 away from the mounting plate 411 can extend to a smaller length, thereby making the overall rigidity of the water outlet structure 42 better, and preventing the water outlet pipes 421 from extending to a large length, resulting in the water outlet pipes 421 being bent under the action of gravity.

[0037] The first driving structure 50 includes a guide hole 51 and an elastic return member 52 .

[0038] The multiple water outlet pipes 421 disposed at the first end of the mounting plate 411, except for the one water outlet pipe 421 farthest from the mounting plate 411, are all provided with a third slide groove 4212 at one end of the other water outlet pipes 421 away from the mounting plate 411, so that the water outlet pipes 421 can slide smoothly. The one water outlet pipe 421 away from the mounting plate 411 of the two adjacent water outlet pipes 421 can be slidably disposed in the third slide groove 4212 of the one water outlet pipe 421 close to the mounting plate 411. The multiple water outlet pipes 421 disposed at the second end of the mounting plate 411 are also provided in the same manner.

[0039] The guide holes 51 include a plurality of guide holes.

[0040] A guide hole 51 is provided at one end of each water outlet pipe 421 close to the mounting member 41, so that the water in the water outlet pipe 421 can be sprayed out, that is, sprayed into the third slide groove 4212 of the adjacent water outlet pipe 421, and under the action of water pressure, each water outlet pipe 421 can move in a direction away from the mounting member 41.

[0041] In two adjacent water outlet pipes 421, the diameter of the guide hole 51 gradually decreases from the water outlet pipe 421 far from the mounting plate 411 to the water outlet pipe 421 close to the mounting plate 411. In this way, water can exert a greater impact force on the third chute 4212 when spraying out.

[0042] The elastic return member 52 is disposed between the water outlet pipe 421 and the inner wall of the third chute 4212 of another water outlet pipe 421 adjacent to the water outlet pipe 421 and located at one end of the water outlet pipe 421 close to the mounting plate 411. After water is not supplied to the water outlet pipe 421, the elastic return force of the elastic return member can pull the two adjacent water outlet pipes 421 to move toward each other.

[0043] The elastic return member 52 includes a tension spring.

[0044] By providing the guide hole 51 and the elastic reset member 52, the use of structures such as the motor can be reduced, thereby reducing the overall weight of the cleaning structure.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, there are multiple water outlet holes 4211 on each water outlet pipe 421, and the multiple water outlet holes 4211 arranged on one water outlet pipe 421 are arranged at intervals.

[0047] The plurality of water outlet holes 4211 include a plurality of hole groups.

[0048] The plurality of hole groups are arranged at intervals along the length direction of the mounting member 41 .

[0049] The water outlet holes 4211 in each hole group are arranged at intervals along the width direction of the mounting member 41 .

[0050] The axes of the multiple water outlet holes 4211 in one hole group are arranged crosswise. The axes of the multiple water outlet holes 4211 are compared to one point.

The water absorption structure 70 can absorb the moisture on the photovoltaic module, reduce the moisture remaining on the photovoltaic module, and prevent the moisture from freezing and causing damage to the photovoltaic module.

[0054] It should be noted that the support rod 60 is rotatably disposed at the second end of the robot arm 20 .

[0055] The water outlet hole 4211 is disposed on a side of the water outlet pipe 421 away from the support rod 60 .

[0056] like Figure 1 and Figure 2 As shown, in this embodiment, the water absorption structure 70 includes a storage box 71 and a flexible water absorption member 72. The storage box 71 is arranged on the support rod 60. The length direction of the storage box 71 is arranged parallel to the length direction of the mounting member 41.

When the water absorbing structure 70 is in the water removal state, the push plate 73 is stationary, and when the water absorbing structure 70 is in the water squeezing state, the second driving structure drives the push plate 73 to move to squeeze the flexible water absorbing member 72. When the push plate 73 moves, it can squeeze the flexible water absorbing member 72, and then squeeze out the water in the flexible water absorbing member 72, so that the flexible water absorbing member 72 can be used again.

[0059] The second driving structure includes a first driving member and a screw rod drivingly matched with the first driving member, and the screw rod is threadedly matched with the push plate 73 .

[0060] The screw rod is rotatably disposed on the accommodation box 71 .

[0062] The first driving member includes a first driving motor.

[0063] like Figure 1 and Figure 2 As shown, in this embodiment, the cleaning device also includes a drying structure 80 arranged on the support rod 60, and the drying structure 80 includes a heater, a hot air gun and an air outlet pipe 81. The heater and the hot air gun are arranged on the mobile vehicle 10, and the air outlet pipe 81 is arranged on the support rod 60. The hot air gun is connected between the air outlet pipe 81 and the heater, and a plurality of air outlet holes are arranged on the air outlet pipe 81. The hot air gun can blow out the heat generated by the heater, and then the heat flows out through the air outlet pipe 81, thereby blowing hot air to the photovoltaic module, so that the residual moisture on the photovoltaic module can evaporate.

[0064] like Figure 1 and Figure 2 As shown, in this embodiment, the cleaning structure 40, the water absorbing structure 70 and the air outlet pipe 81 are sequentially arranged along the length direction of the support rod 60, the length direction of the support rod 60 is arranged at an angle with the length direction of the mounting member 41, and the cleaning structure 40, the water absorbing structure 70 and the drying structure 80 are all movably arranged along the length direction of the support rod 60. Such an arrangement enables the relative distance between the cleaning structure 40, the water absorbing structure 70 and the drying structure 80 to be reduced when the cleaning device is not in use, so that the cleaning structure 40, the water absorbing structure 70 and the drying structure 80 are convenient for storage.

[0065] The length direction of the support rod 60 is perpendicular to the length direction of the mounting member 41 .

[0066] The cleaning device also includes a control system.

[0067] The control system includes a computer, a touch screen and a control panel, which can realize the control of the mechanical arm 20 and the mobile vehicle 10.

[0068] The cleaning device is also equipped with a variety of sensors and detection equipment, which can automatically identify dirt and moisture on the surface of photovoltaic modules, and perform precise cleaning and drying according to actual conditions.

[0069] The cleaning device also has autonomous navigation and obstacle avoidance capabilities, and can move and work autonomously in different terrain environments.

[0070] The cleaning device can be remotely controlled and monitored via the Internet.

[0071] The cleaning device adopts advanced energy-saving technology, which can effectively reduce energy consumption and noise and reduce the impact on the environment.

[0072] After the cleaning device detects the humidity through the humidity sensor, it adjusts the position of the air outlet pipe 81 to perform accurate drying. After the drying is completed, the cleaning structure 40 and the drying structure 80 are closed, and the control system is started to monitor and manage the working status.

[0073] The cleaning device also includes a second driving member and a third driving member.

[0074] The second driving member and the third driving member are both disposed on the accommodating box 71 .

[0075] The second driving member is drivingly matched with the mounting member 41 to adjust the distance between the cleaning structure 40 and the water absorbing structure 70 .

[0076] The third driving member cooperates with the drying structure 80 to adjust the distance between the drying structure 80 and the water absorbing structure 70 .

[0077] When the cleaning device is used, the second driving member can drive the cleaning structure 40 to move toward the direction close to the water absorption structure 70, and the third driving member can drive the drying structure 80 to move toward the direction close to the water absorption structure 70, so that the cleaning structure 40, the water absorption structure 70 and the drying structure 80 occupy less space, which is convenient for the storage and transportation of the cleaning device.

[0078] The second driving member is a first cylinder.

[0079] The third driving member is a second cylinder.

[0080] The cleaning device further includes a plurality of stop structures, and the plurality of stop structures are arranged in one-to-one correspondence with the plurality of water outlet pipes 421 .

[0081] Each stop structure includes a fourth driving member and a stop member drivingly matched with the fourth driving member.

[0082] The stopper is movably disposed in the water outlet pipe 421 .

[0083] The stopper is provided with a conducting hole.

[0084] The stopper has an on position and a stop position.

[0085] When the stopper is in the conducting position, the conducting hole is connected to the guide hole, and water can flow through the guide hole to the third chute of the water outlet pipe adjacent to the guide hole.

[0086] When the stopper is at the stopping position, the conducting hole and the guide hole are arranged in a staggered manner, that is, the stopper can block the guide hole.

[0087] The fourth driving member is the third cylinder.

[0088] The stopper comprises a stopper plate, and the conducting hole is arranged on the stopper plate and penetrates through the thickness direction of the stopper plate.

[0089] The computer is signal-connected with the second driving member, the third driving member and a plurality of fourth driving members.

[0090] When the cleaning device is running, the two stop structures farthest from the mounting plate 411, and the fourth driving members of the two stop structures controlled by the computer are both running, so that the stop members are switched from the conduction position to the stop position, so that under the water pressure, the two water outlet pipes 421 farthest from the mounting plate 411 are moved in the direction away from the mounting plate 411.

[0091] When the distance that a water outlet pipe 421 away from the mounting plate 411 of two adjacent water outlet pipes moves in the direction away from the mounting plate 411 reaches the maximum, the fourth driving member of the stop structure on a water outlet pipe 421 close to the mounting plate 411 operates to switch the stop member from the conduction position to the stop position.

[0092] The water outlet pipe is located on a portion of the structure within the third chute 4212 and is provided with a top plate.

[0093] A fourth chute is also arranged in the water outlet pipe.

[0094] The fourth chute is connected to the third chute.

[0096] A fifth slide groove is arranged on the side wall of the first slide groove 4111, and a trigger button is arranged on the inner wall of the second end of the fifth slide groove away from the mounting plate 411 to enable a switch member on a water outlet pipe closest to the mounting plate 411 to be opened.

[0097] The water pressure in the plurality of water outlet pipes 421 gradually increases from the outermost water outlet pipe 421 farthest from the mounting plate 411 to the closest water outlet pipe 421 to the mounting plate 411, so that the relative positions of the water outlet pipe 421 farthest from the mounting plate 411 and the water outlet pipe 421 close to the mounting plate 411 can remain unchanged.

[0098] When the cleaning device of this embodiment is in use, the switch on the water outlet pipe 421 farthest from the mounting plate 411 is opened, water flows out through the multiple water outlet holes 4211, and flows through the guide hole 51 into a water outlet pipe 421 adjacent to the water outlet pipe 421 farthest from the mounting plate 411, so that under the action of water pressure, the water outlet pipe 421 farthest from the mounting plate 411 can move in a direction away from the mounting plate 411.

[0099] Except for the water outlet pipe 421 farthest from the mounting plate 411, the rest of the water outlet pipes 421 move according to the following steps: one of the two adjacent water outlet pipes 421 is a first water outlet pipe and the other is a second water outlet pipe, and a part of the structure of the first water outlet pipe is located inside the second water outlet pipe. When the top plate on the first water outlet pipe contacts the trigger button on the inner wall of the fourth chute of the second water outlet pipe, the computer receives the signal of the trigger button to switch the stopper provided on the second water outlet pipe to the conducting position, and to open the switch on the first water outlet pipe, so that water can be sprayed out, and at the same time, the stopper on the first water outlet pipe is switched to the stopper position, so that the first water outlet pipe can extend out of the second water outlet pipe, and the first water outlet pipe can stably discharge water.

[0100] When the water outlet pipe 421 closest to the mounting plate 411 moves to the top plate and contacts the trigger button in the fifth slide slot, the switch member arranged on the water outlet pipe 421 closest to the mounting plate is opened.

[0101] When the cleaning device stops running, multiple switch components are closed.

[0102] The cleaning device of this embodiment can complete the cleaning and drying of photovoltaic modules at the same time, and has the characteristics of high efficiency, environmental protection and low cost.

[0103] The device can realize intelligent operation through an automated control system, reducing labor costs and operating difficulties, while also improving cleaning and drying effects.

[0104] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0105] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0106] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
