Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a spraying device. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] In the field of photovoltaic equipment technology, photovoltaic panels are important components for photovoltaic equipment to generate electricity. The amount of power generated by photovoltaic equipment is affected by the amount of light received by the photovoltaic panels. Usually, in order to improve the problem of reduced light efficiency of photovoltaic panels after long-term use, a coating liquid is usually sprayed on the surface of the photovoltaic panels to increase the service life of the photovoltaic panels and ensure the light efficiency of the photovoltaic panels. Therefore, the coating liquid is evenly sprayed on the surface of the photovoltaic panels before they leave the factory.

[0004] However, the actual use environment of photovoltaic panels is generally in Gobi, desert and other areas, which are far away from the factory. During transportation, multiple photovoltaic panels are usually stacked and transported, which will cause friction on the coating on the photovoltaic panels, accelerating the damage of the coating layer of the photovoltaic panels. Furthermore, photovoltaic panels are affected by their use environment. During use, the surface of photovoltaic panels will be affected by sand and stone scratches and wind erosion from the environment, and the coating on its surface will also age rapidly, resulting in a decrease in the light intake efficiency of the photovoltaic panels. Therefore, in order to extend the service life of the coating of photovoltaic panels, factories usually have professional spray engineers who arrive at the installation site of the photovoltaic panels and use professional equipment to spray the photovoltaic panels to be installed, so as to reduce the chance of the coating of the photovoltaic panels suffering from non-use wear. At the same time, if the coating of photovoltaic panels that have been used for a long time ages and falls off, the staff of the photovoltaic power station will usually wait until the coating of most photovoltaic panels has failed, and then notify the photovoltaic panel manufacturer to send engineers to unload multiple photovoltaic panels, clean them, and then re-spray them with professional equipment. This operation requires the professional equipment to be arranged according to the actual on-site environment, which requires more preparation processes, seriously affecting the operating efficiency of the photovoltaic power station.

[0005] In response to the above problems, if it is necessary to spray the installed photovoltaic panels, for example, by using walking devices such as mobile robot vehicles, since these walking devices only walk on the photovoltaic panels, they do not consider the uniformity and solidification time required for the film spraying. Therefore, when these walking devices turn, they will cause torsional friction scratches on the photovoltaic panels, affecting the spraying effect; the walking paths of these walking devices will also cause the sprayed film layer to be repeatedly crushed before it solidifies, destroying the spray layer, and these walking devices will also have dead angles for spraying when moving along the set path; at the same time, without considering the walking device, only using high-altitude spraying devices to spray the installed photovoltaic panels, due to the limitation of the operating angle of the operating machinery, it is impossible to achieve the effect of uniformly spraying the film layer on the photovoltaic panels.

[0006] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely explaining the technical solution of the present utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present utility model.

[0047] As Figure 1 and Figure 2 shown, this utility model provides a spraying device, and the spraying device includes:

[0048] A skeleton structure 1, on which a spraying assembly 4 is provided, and a first moving structure 11 capable of moving along a first direction A on a working surface is provided at the bottom of the skeleton structure 1;

[0049] A line-changing structure 2, which is movably arranged on the skeleton structure 1 up and down, and a second moving structure 21 capable of moving along a second direction B on the working surface is provided at the bottom of the line-changing structure 2, and there is an included angle between the first direction A and the second direction B;

[0050] Switching structure 3, the switching structure 3 is connected between the skeleton structure 1 and the line feed structure 2, the switching structure 3 can push the line feed structure 2 to move between a first position and a second position in the vertical direction. When the line feed structure 2 is at the first position, the first moving structure 11 abuts against the working surface, and the second moving structure 21 is separated from the working surface; when the line feed structure 2 is at the second position, the second moving structure 21 moves down to abut against the working surface, and the first moving structure 11 is lifted up to be separated from the working surface.

[0051] The spraying device provided by the present utility model can realize that the spraying device can travel in two directions through the skeleton structure 1 and the line feed structure 2, that is, after traveling along the spraying direction on the working surface of the photovoltaic panel, there is no need to turn on the photovoltaic panel, and the line feed structure 2 is directly used to move to another photovoltaic panel, avoiding the problem that the traveling structure generates friction on the surface of the photovoltaic panel when turning, and also avoiding the problem that the traveling structure damages the already sprayed but unstable coating layer due to turning.

[0052] In this embodiment, the spraying assembly 4 is arranged on the peripheral side wall of the skeleton structure 1. In other embodiments, the setting position of the spraying assembly 4 is not specifically limited. In this embodiment, a first moving structure 11 is arranged at the bottom of the skeleton structure 1, the first moving structure 11 can abut against the working surface of the photovoltaic panel, and the first moving structure 11 can drive the skeleton structure 1 to move along the first direction A on the working surface. In this embodiment, the first direction A is set as the length direction of the photovoltaic panel, that is, the spraying assembly 4 can perform spraying operations on the working surface of the photovoltaic panel in the first direction A.

[0053] In this embodiment, the line feed structure 2 is arranged on the skeleton structure 1 so as to be movable up and down. In one embodiment, the line feed structure 2 passes through the internal cavity of the skeleton structure 1, and the line feed structure 2 can pass out through the opening at the bottom of the skeleton structure 1; in another embodiment, the line feed structure 2 can also be arranged on the side wall of the skeleton structure 1, and no specific limitation is made thereto; in this embodiment, a second moving structure 21 is arranged at the bottom of the line feed structure 2, the first moving structure 11 can abut against the working surface of the photovoltaic panel, and the second moving structure 21 can drive the line feed structure 2 to move along the second direction B on the working surface of the photovoltaic panel. There is an included angle between the first direction A and the second direction B, that is, the first direction A and the second direction B are different directions.

[0054] In this embodiment, a switching structure 3 is provided between the frame structure 1 and the line feed structure 2. The switching structure 3 can push the line feed structure 2 to move between a first position and a second position. In this embodiment, the line feed structure 2 is disposed inside the frame structure 1. The first position is located in the internal cavity of the frame structure 1. In the state where the line feed structure 2 is at the first position, the second moving structure 21 at the bottom of the line feed structure 2 is separated from the working surface. In a specific embodiment, the second moving structure 21 is also located inside the frame structure 1. In another specific embodiment, the second moving structure 21 is suspended above the working surface and does not enter the inside of the frame structure 1. No specific limitation is made thereto. In this embodiment, the line feed structure 2 is at the first position under the push of the switching structure 3. The spraying device is supported and abutted against the working surface through the frame structure 1 and the first moving structure 11, and the spraying device is moved through the first moving structure 11. In this embodiment, the switching structure 3 can also push the line feed structure 2 to move to the second position. The second position in this embodiment is a position where the second moving structure 21 is relatively below the first moving structure 11 with respect to the first moving structure 11. That is, in the state where the line feed structure 2 is at the second position, the second moving structure 21 abuts against the working surface, and the switching structure 3 lifts the frame structure 1, thereby driving the first moving structure 11 to be lifted upward in the vertical direction, and the first moving structure 11 is separated from the working surface.

[0055] In this embodiment, the switching structure 3 switches the line feed structure 2 between the first position and the second position, so as to realize the switching between the modes of the spraying device moving along the first direction A or moving along the second direction B. The spraying device can freely switch the moving direction according to the progress of the current spraying operation; at the same time, it can also avoid excessive frictional damage to the working surface, which is beneficial to ensuring the integrity of the coating layer.

[0056] In this embodiment, the switching action of the switching structure 3 can be manual operation by an operator or can also be electrically controlled. That is, the switching structure 3 is a high-pressure gas telescopic cylinder controlled by a solenoid valve, and the operator can control the switching structure 3 to execute the instruction of switching the line feed structure 2 between the first position and the second position through a remote controller.

[0057] As Figure 1 and Figure 2 shown, in a specific embodiment, the first direction A and the second direction B are in the same plane, and the included angle is greater than 0° and less than 180°.

[0058] In this embodiment, the included angle between the first direction A and the second direction B can be set according to the direction required by the spraying device, that is, it can be set according to the path of the spraying operation or the structure of the photovoltaic panel. In this embodiment, the included angle between the moving direction of the first moving structure 11 and the moving direction of the second moving structure 21 is fixed, that is, the included angle between the first direction A and the second direction B is fixed. In other embodiments, the included angle between the moving direction of the first moving structure 11 and the moving direction of the second moving structure 21 is adjustable, that is, the included angle between the first direction A and the second direction B is adjustable, and no specific limitation is made thereto. In this embodiment, both the first direction A and the second direction B are located in the same plane, that is, the working surface of the photovoltaic panel.

[0059] As Figure 1 and Figure 2 shown, in a specific embodiment, the included angle is 90°.

[0060] In this embodiment, the first direction A and the second direction B are perpendicularly arranged, that is, the moving direction of the first moving structure 11 and the moving direction of the second structure are perpendicular. After the spraying device sprays along the first direction A, it is switched by the switching structure 3 so that the second moving structure 21 abuts against the working surface. Further, the spraying device moves from one photovoltaic panel to another along the second direction B to realize a serpentine spraying path.

[0061] As Figure 1 and Figure 2 shown, in a specific embodiment, the first moving structure 11 has a plurality of first moving members 111, and the plurality of first moving members 111 are correspondingly arranged at the vertex positions and / or edge positions of the bottom of the frame structure 1;

[0062] The second moving structure 21 has a plurality of second moving members 211, and the plurality of first moving members 111 are correspondingly arranged at the vertex positions and / or edge positions of the bottom of the frame structure 1.

[0063] For the spraying device provided by the present utility model, by arranging the first moving members 111 of the first moving structure 11 at the vertex or edge positions of the bottom of the frame structure 1, the frictional damage to the photovoltaic panel during the movement of the first moving members 111 can be further reduced. At the same time, the contact between the first moving members 111 and the already sprayed photovoltaic panel can be minimized, thereby reducing the damage to the coating layer by the first moving structure 11. Meanwhile, by arranging the second moving members 211 of the second moving structure 21 at the vertex or edge positions of the bottom of the line-changing structure 2, the frictional damage to the photovoltaic panel and the damage to the coating layer during the movement of the second moving members 211 can also be reduced.

[0064] In this embodiment, the bottom of the frame structure 1 is a cubic structure. A plurality of first moving members 111 of the first moving structure 11 can be respectively arranged at the four vertex positions of its cube. The bottom of the line-changing structure 2 is also a cubic structure. A plurality of second moving members 211 of the second moving structure 21 can be respectively arranged at the four vertex positions of its cube, so as to avoid the problem that the first moving structure 11 and the second moving structure 21 have too many rolling friction areas on the surface of the photovoltaic panel during the moving process, and avoid affecting the solidification and stability of the coating layer after the spraying device sprays the working surface of the photovoltaic panel. In other embodiments, a plurality of first moving members 111 of the first moving structure 11 can be respectively arranged on the edge side parallel to the first direction A at the bottom of the frame structure 1, that is, the rolling area of the plurality of first moving members 111 on the surface of the photovoltaic panel during the moving process is a straight line parallel to the first direction A, so as to minimize the rolling area of the first moving members 111 on the photovoltaic panel; similarly, a plurality of second moving members 211 of the second moving structure 21 can be respectively arranged on the edge side parallel to the second direction B at the bottom of the line-changing structure 2, that is, the rolling area of the plurality of second moving members 211 on the surface of the photovoltaic panel during the moving process is a straight line parallel to the second direction B, so as to minimize the rolling area of the second moving members 211 on the photovoltaic panel.

[0065] As Figure 1 and Figure 2 shown, in a specific embodiment, the first moving structure 11 further has an auxiliary moving member 112 capable of moving along the first direction A. The auxiliary moving member 112 is connected to the first moving member 111, and an annular groove 113 is formed between the auxiliary moving member 112 and the first moving member 111, so that at least one side edge of the working surface is clamped into the annular groove 113.

[0066] The spraying device provided by the present utility model is provided with an auxiliary moving member 112, which can improve the moving stability of the spraying device on the photovoltaic panel. That is, the auxiliary moving member 112 can clamp the spraying device on the side edge of the photovoltaic panel. In the actual installation site where the photovoltaic panel is installed obliquely, during the moving process of the spraying device, relying on the auxiliary moving member 112 to be clamped on the side edge of the photovoltaic panel at a higher position to avoid the photovoltaic panel from slipping. At the same time, by using the auxiliary moving member 112, the bottom area of the spraying device can be further reduced, that is, it is not necessary to set the bottom of the spraying device to the same size as the width of the photovoltaic panel to realize the spraying operation. It can be clamped on the edge of the photovoltaic panel at a higher position with a smaller size, and the spraying operation of the photovoltaic panel can be realized by lengthening the spraying assembly 4.

[0067] In this embodiment, the diameter of the auxiliary moving member 112 is larger than that of the first moving member 111. The auxiliary moving member 112 is attached to the outer end face of the first moving member 111. In other embodiments, there are no restrictions on the specific installation position and size of the auxiliary moving member 112. In this embodiment, the auxiliary moving member 112 and the first moving member 111 form an annular groove 113, and at least one side edge of the working surface is clamped into the annular groove 113. The annular groove 113 in this embodiment is composed of the moving surface of the first moving member 111 and the inner end face of the auxiliary moving member 112. Among them, the moving surface of the first moving member 111 abuts against the working surface, and the inner end face of the auxiliary moving member 112 abuts against one side edge of the working surface, realizing the clamping of the spraying device so that the spraying device can be stable on the working surface when spraying along the first direction A.

[0068] As Figure 1 and Figure 2 shown, in a specific embodiment, the first moving member 111, the second moving member 211, and the auxiliary moving member 112 are all rollers;

[0069] The radius of the auxiliary moving member 112 is larger than that of the first moving member 111. The auxiliary moving member 112 and the first moving member 111 are coaxially arranged, and one end face of the auxiliary moving member 112 is connected to one end face of the first moving member 111 to form the annular groove 113 between the auxiliary moving member 112 and the first moving member 111.

[0070] The spraying device provided by the present utility model, by adopting the structural form of rollers, can reduce the pressure exerted by the first moving structure 11 or the second moving structure 21 on the working surface of the photovoltaic panel. At the same time, adopting the structure of rollers can also ensure that the working surface will not be subjected to too much extrusion force and friction force when being clamped into the annular groove 113.

[0071] In this embodiment, the inner end face of the auxiliary moving member 112 is connected to the outer end face of the first moving member 111, and the first moving member 111 and the auxiliary moving member 112 are coaxially arranged. Since the radius of the auxiliary moving member 112 is larger than that of the first moving member 111, the annular groove 113 is composed of the rolling side surface of the first moving member 111 and the inner end face of the auxiliary moving member 112. Among them, the moving surface of the first moving member 111 abuts against the working surface, and the inner end face of the auxiliary moving member 112 protruding from the first moving member 111 abuts against one side edge of the working surface, realizing the clamping of the spraying device.

[0072] In this embodiment, the drive motor is arranged at the top of the line-changing structure 2, and the drive motor is respectively connected to the first moving member 111 or the second moving member 211 through a belt, which can better ensure the reliability of power transmission and the stability of power output. At the same time, in order to solve the problem that the rollers of the first moving member 111 or the second moving member 211 do not rotate during the walking process of the equipment, a belt is used to connect the first moving member 111 or the second moving member 211 through the power wheel of the drive motor, which can ensure that all rollers can be driven by the drive motor to operate, and prevent the rollers from rubbing against the surface of the photovoltaic panel after locking, resulting in damage to the surface of the photovoltaic panel.

[0073] In this embodiment, the battery is arranged at the top of the line break structure 2, and the battery is electrically connected to the drive motor. The drive motor can be controlled by a remote control, thereby controlling the spray device to move along the first direction A or along the second direction B. At the same time, the automatic operation program of the spray component 4 can also be set. After the parameters of the automatic operation program are set on the remote control, the remote control can be used for one-button operation.

[0074] like Figure 4 As shown, in a specific embodiment, the spray assembly 4 has at least one spray pipe 41, and the spray pipe 41 has a plurality of nozzles 411, and the plurality of nozzles 411 are arranged at intervals along the axis of the spray pipe 41;

[0075] The axis of the nozzle 41 is parallel to the working surface and perpendicular to the first direction A.

[0076] The spraying device provided by the utility model is configured such that the nozzle 41 is parallel to the working surface and perpendicular to the first direction A, so that the nozzle 41 can be perpendicular to the first direction A to evenly spray the coating liquid, thereby forming a stable and uniform coating layer on the photovoltaic panel.

[0077] In this embodiment, the nozzle 41 is provided with a plurality of nozzles 411, which are arranged at intervals along the axis of the nozzle 41, and the opening direction of the nozzle 411 is set vertically downward, and the nozzle 41 is always parallel to the working surface, so that the liquid sprayed from each nozzle 411 needs to move the same distance to reach the working surface, so that the liquid spraying effect is more uniform. At the same time, the nozzle 41 is set perpendicular to the first direction A, so that the area sprayed by the nozzle 41 can be uniformly moved along the first direction A, avoiding the problem that the spraying device reaches one end of the photovoltaic panel and there are still some areas that are not sprayed.

[0078] like Figure 2 and Figure 3 As shown, in a specific embodiment, there are multiple nozzles 41 , and the multiple nozzles 41 are respectively arranged on opposite sides of the skeleton structure 1 .

[0079] The spraying device provided by the utility model can achieve complete spraying of the photovoltaic panel by arranging multiple spray pipes 41 and respectively arranging the multiple spray pipes 41 on opposite sides of the frame structure 1. That is, when the spray pipes 41 are usually installed only on one side of the spraying device, there will be a situation where when the spraying device reaches one end of the photovoltaic panel, there is still an area of the photovoltaic panel at the bottom of the spraying device that is not sprayed. By respectively arranging multiple spray pipes 41 on opposite sides of the frame structure 1, when the spraying device is about to reach one end of the photovoltaic panel or when the spraying device is about to start moving from one end of the photovoltaic panel, the spray pipes 41 on the other side can be turned on in advance, and the area at the bottom of the spraying device can be sprayed, improving the spraying efficiency and spraying working ability of the spraying device, and solving the problem that the last or the first solar panel cannot be sprayed.

[0080] In this embodiment, multiple spray pipes 41 are respectively arranged on opposite sides of the frame structure 1, that is, multiple spray pipes 41 are respectively arranged on the front and rear sides of the frame structure 1 when it moves along the first direction A, so as to spray the photovoltaic panel surface in the moving direction of the spraying device. In another embodiment, multiple spray pipes 41 can also be arranged on the same side of the spraying device, and the multiple spray pipes 41 are axially connected and communicated, and no limitation is made thereto.

[0081] As Figure 2 and Figure 3 shown, in a specific embodiment, the spraying assembly 4 has a wind shield 42, and the wind shield 42 covers the upper part of the spray pipe 41.

[0082] The spraying device provided by the utility model can avoid the problem that the coating liquid sprayed by the spray pipe 41 is affected by strong wind or gust in the outdoor environment, resulting in uneven distribution of the coating liquid sprayed on the photovoltaic panel during the spraying operation by arranging the wind shield 42.

[0083] In this embodiment, the wind shield 42 covers the upper part of the spray pipe 41, which can avoid the wind from top to bottom or the wind from the left and right sides of the spray pipe 41.
