[0037] like Figure 1As shown, the photovoltaic panel film 1 spraying device includes a fixed carrier 2, which is in the shape of "L" with a vertical surface and a bottom plane as shown; a movable carrier 3 is arranged on one side of the vertical surface of the fixed carrier 2, and the movable carrier 3 is arranged opposite to the vertical surface of the fixed carrier 2, and the movable carrier 3 can slide on the bottom plane of the fixed carrier 2 to approach or move away from the vertical surface of the fixed carrier 2; a plurality of telescopic supports 4 are rotatably connected between the vertical surface of the fixed carrier 2 and the movable carrier 3 with variable length, and the telescopic supports 4 can be stretched or shortened following the movement of the movable carrier 3;

[0038] A spraying mechanism 7 is arranged on the movable carrier 3, and the spraying mechanism 7 has a spraying path on the truss 8 fixed on the fixed carrier 2, and further, the spraying mechanism 7 includes input and output parts, the input part is fixed on the movable carrier 3, and the output part is fixed on the truss 8, so that the movement of the movable carrier 3 does not drive the input part, and does not interfere with the movement of the output part, so that no matter how the movable carrier 3 moves, the spraying path of the output part can cover the spacing width between the vertical surface of the fixed carrier 2 and the movable carrier 3, so that the output part sprays the photovoltaic panel film 1 on the plurality of telescopic supports 4 between the fixed carrier 2 and the movable carrier 3, preferably for coating the reflective coating;

[0039] An adjusting mechanism 6 is arranged between the fixed carrier 2 and the movable carrier 3, and the adjusting mechanism 6 drives the movable carrier 3 to move on the fixed carrier 2.

[0040] As shown in the figure, Figure 2 The plurality of telescopic supports 4 are arranged as shown in the figure, that is, three telescopic supports 4 are arranged on each side, and the specific arrangement of the plurality of telescopic supports 4 is not limited, only the photovoltaic panel film 1 passing through the plurality of telescopic supports 4 in turn can form a flat coating surface 5 on the top between the fixed carrier 2 and the movable carrier 3, and the coating surface 5 is shown on the top in the figure, but it can also be formed on the two side positions to adapt to the layout of other structures such as the spraying mechanism 7, so that the spraying device can move the photovoltaic panel film 1 between the plurality of telescopic supports 4 with the rolling force provided by the winding roller (not shown in the figure), and the moving photovoltaic panel film 1 drives the plurality of telescopic supports 4 to rotate between the fixed carrier 2 and the movable carrier 3, so that the spraying mechanism 7 sprays the reflective coating on the coating surface 5 of the continuously moving photovoltaic panel film 1, and in order to avoid the contact between the one side of the photovoltaic panel film 1 with the telescopic supports 4 before the coating is dry, the moving speed of the photovoltaic panel film 1 between the plurality of telescopic supports 4 is less than the natural air drying time required for coating, or it is used with a fast drying component (not shown in the figure).

[0041] As shown in the figure, Figure 3As shown, each of the plurality of telescopic supports 4 comprises a first sleeve 41 and a telescopic tube 42, the first sleeve 41 is rotationally connected to the fixed carrier 2 and sleeved outside the telescopic tube 42, one end of the telescopic tube 42 is rotationally connected to the movable carrier 3, a limiting structure is arranged between the first sleeve 41 and the telescopic tube 42, and the limiting structure is used to rotate the telescopic tube 42 along with the rotation of the first sleeve 41;

[0042] The limiting structure is composed of at least two limiting grooves (one end of the limiting groove is communicated with the end of the first sleeve 41) opened on the first sleeve 41 and at least two convex strips fixed on the outer surface of the telescopic tube 42, the convex strips are matched in size with the limiting grooves, and the convex strips are located in the limiting grooves;

[0043] The movable carrier 3 moves to pull or push the telescopic tube 42 to move in the first sleeve 41, so that the length of the part of the telescopic tube 42 protruding outside the first sleeve 41 is lengthened or shortened, when lengthened, the overall length of the telescopic support 4 is adjusted to increase, when shortened, the overall length of the telescopic support 4 is adjusted to shorten, and under the connection limitation of the limiting groove and the convex strip, only telescopic movement is allowed, and the telescopic tube 42 cannot rotate in the first sleeve 41, or the first sleeve 41 cannot rotate outside the telescopic tube 42, but the first sleeve 41 and the telescopic tube 42 rotate under the mutual force.

[0044] As shown in Figure 4 and Figure 5 The adjusting mechanism 6 comprises a connecting frame 61, a second sleeve 62, a screw rod 63 and a hand wheel 64, the connecting frame 61 is fixed on one side of the hollow part of the movable carrier 3, the second sleeve 62 is fixed on the middle part of one side of the connecting frame 61 and has an internal thread inside, the screw rod 63 is threadedly connected inside the second sleeve 62, one end of the screw rod 63 is rotationally connected to the middle part of the fixed carrier 2 and protrudes a part, and the hand wheel 64 is fixed on the part of the screw rod 63 protruding outside the fixed carrier 2;

[0045] The screw rod 63 is rotated by the hand wheel 64, and the second sleeve 62 threadedly connected with the screw rod 63 does not rotate along with the rotation of the screw rod 63 due to being fixed with the connecting frame 61, but the screw rod 63 rotates inwardly or outwardly away from the second sleeve 62, but due to the rotational connection of one end of the screw rod 63 with the fixed carrier 2, the second sleeve 62 moves forward or backward outside the screw rod 63 under the rotation of the screw rod 63, so as to pull or push the movable carrier 3 to move on the fixed carrier 2 through the connecting frame 61, so as to change the distance between the fixed carrier 2 and the movable carrier 3.

[0046] As shown in Figures 6-9The spraying mechanism 7 includes a paint tank 71, a high-pressure pump 72, a three-way valve 73, two hoses 74, two coating spray heads 75 and two linear modules 76. The paint tank 71 is fixed on one side of the connecting frame 61, the high-pressure pump 72 is fixed on one side of the paint tank 71, the inlet of the high-pressure pump 72 is communicated with the outlet of the paint tank 71, the three-way valve 73 is installed on the outlet of the high-pressure pump 72, one end of the two hoses 74 is respectively communicated with the other two interfaces of the three-way valve 73, the other end of the two hoses 74 is respectively communicated with the two coating spray heads 75, the two linear modules 76 are connected end to end along a straight line and are fixed on the top of the truss 8, and the two coating spray heads 75 are respectively fixed on the reciprocating moving parts of the two linear modules 76.

[0047] The paint tank 71 stores the paint used for spraying to form a reflective coating, and the paint enters from the inlet on one side of the top of the paint tank 71. The high-pressure pump 72 is a device that can increase the pressure of a fluid, usually compressing a low-pressure liquid mechanically to produce high pressure. When the high-pressure pump 72 is connected to the paint in the paint tank 71, it will compress the paint liquid so that it can flow quickly and at high speed in the hose 74, until it flows to the coating spray head 75 at one end and is sprayed out. The paint passing through the coating spray head 75 will be atomized into tiny droplets and sprayed out, the spraying shape expands outward in a fan shape and adheres to the to-be-coated surface 5 of the photovoltaic panel film 1. Since the coating spray head 75 is provided on the reciprocating moving part of one linear module 76, it drives the coating spray head 75 to move on the to-be-coated surface 5 of the photovoltaic panel film 1, so that the sprayed paint can cover the to-be-coated surface 5 without leaving dead angles.

[0048] The linear module 76 is a mechanical device that realizes linear motion, mainly including synchronous belt drive type and screw drive type. In this embodiment, both types can be used, and preferably the linear module 76 is provided with a flexible closed cover based on the above two types. The flexible closed cover can drive the slide of the linear module 76 to reciprocate without limitation, and can avoid the sprayed paint from entering the linear module 76 as much as possible, and can reduce the corrosion of the driving parts in the linear module 76 as much as possible. In addition, the linear module 76 uses a servo or stepping motor that can rotate forward and backward as a driving source. The motor is controlled by a controller to control the stroke of the slide to reciprocate. Therefore, when the photovoltaic panel film 1 with a width equal to or less than the movement stroke of one linear module 76 needs to be sprayed, the controller controls the stroke of the slide to be consistent with the width of the photovoltaic panel film 1, and the three-way valve 73 is closed to communicate with the other hose 74 and the high-pressure pump 72, so that the compressed paint can only communicate from one hose 74. In this way, the photovoltaic panel film 1 with the width can be sprayed, so as to avoid the sprayed paint from the coating spray head 75 from spraying on other parts on both sides of the photovoltaic panel film 1, or to avoid the attachment of paint near both sides of the photovoltaic panel film 1.

[0049] When the width dimension of the photovoltaic panel film 1 greater than one or equal to two linear module 76 movement stroke needs to be sprayed, first, the controller controls the reciprocating movement of the slide of the linear module 76 to be consistent with the width dimension of the photovoltaic panel film 1, that is, the movement stroke of the two linear module 76 slide coating spray head 75 is consistent with the width dimension of the photovoltaic panel film 1, and the three-way valve 73 is used to communicate the two hoses 74 with the high-pressure pump 72, so that the coating can be moved reciprocally with the two coating spray heads 75, that is, the coating can be attached to the surface 5 to be coated of the width dimension of the photovoltaic panel film 1 without dead angle and a small amount of overflow on other parts.

[0050] It should be noted that as shown in Figure 1 The sliding member is provided between the movable carrier 3 and the fixed carrier 2 and between the movable carrier 3 and the truss 8, the movable carrier 3 can move between the fixed carrier 2 and the truss 8 through the sliding member, and the movable carrier 3 moves to drive the length of the plurality of telescopic supporting members 4 to be stretched or shortened.
