[0037] Please refer to Figure 1 and Figure 2 In a preferred embodiment of the present application, a tea garden photovoltaic system comprises a support frame 100, photovoltaic panels 200 and a sliding driving mechanism 300.

[0038] A roof 110 is installed on the upper end of the support frame 100, and the roof 110 is provided with a light inlet. The photovoltaic panels 200 are provided in multiple groups, and the multiple groups of photovoltaic panels 200 are slidingly installed on the roof 110 in the front-rear direction and parallel to the roof 110. The multiple groups of photovoltaic panels 200 are staggered in the height direction of the photovoltaic panels 200 to enable different groups of photovoltaic panels 200 to slide to an overlapping state. The sliding driving mechanism 300 is used to drive the photovoltaic panels 200 to slide and adjust the position. It can be understood that the connecting line of the photovoltaic panels 200 connected with the external circuit equipment has a redundant length to adapt to the change of the sliding position.

[0039] The tea garden photovoltaic system effectively combines the functions of photovoltaic power generation and light regulation, the roof at the upper end of the support frame is provided with a light inlet, a light-transmitting plate 111 is installed, the transmission of natural light is ensured, meanwhile, the photovoltaic panel 200 is slidingly installed along the roof 110, the position is adjusted through a sliding driving mechanism, dynamic control of the light condition is realized, when the tea tree needs sufficient light, the photovoltaic panel is adjusted to the position to make it as much as possible not to fold the light to irradiate the tea tree, when the tea tree needs to be folded, the photovoltaic panel can effectively shield; and through the staggered arrangement of the photovoltaic panel and the function of sliding to the overlapping state, the photovoltaic panel can be overlapped together when light is needed, the shielding of the tea tree light is reduced, and the growth requirement of the tea tree is ensured. When hail is encountered, the photovoltaic panel can also shield the light inlet and protect and shield the tea tree. This design not only improves the light efficiency of the tea garden, but also provides clean energy for the system through photovoltaic power generation, and reduces the energy consumption. Overall, the system realizes the effective combination of agricultural light and clean energy, improves the production efficiency and economic benefit of the tea garden.

[0040] It can be understood that, in order to shield rainwater for internal electrical equipment, in some embodiments, the light inlet is provided with a light-transmitting plate 111, the light-transmitting plate 111 is made of glass or acrylic material, in order to ensure the structural strength and facilitate installation, the light inlet and the light-transmitting plate 111 are arranged in a matrix, so that the size of the light inlet is not too large due to the single light inlet.

[0041] In some embodiments of the present application, a self-cleaning assembly is further included for cleaning the upper surface of the photovoltaic panel 200, so as to improve the light energy utilization rate of the photovoltaic panel 200 and reduce the frequency of manual maintenance.

[0042] Referring to Figure 2 , Figure 5 , Figure 6 and Figure 8In further embodiments of the present application, the self-cleaning assembly comprises a first brush plate 400 and a second brush plate 410, the first brush plate 400 is installed on the bottom of the photovoltaic panel 200 at least higher than a group of photovoltaic panels 200 to brush the photovoltaic panel 200 below it; it can be understood that the first brush plate 400 is installed on the bottom of all photovoltaic panels 200 except the lowest group of photovoltaic panels 200, and the first brush plate 400 is installed on the bottom of the photovoltaic panel 200 only when there are other photovoltaic panels 200 below the sliding path of the photovoltaic panel 200, that is, the multiple groups of photovoltaic panels 200 comprise a group of low photovoltaic panels in the lowest position and high photovoltaic panels above the sliding path of the low photovoltaic panels, the high photovoltaic panels are at least two groups and are staggered in the height direction, and the first brush plate 400 is installed on the high photovoltaic panels. Since there are other photovoltaic panels 200 below the photovoltaic panel 200 on which the first brush plate 400 is installed, when the upper and lower adjacent photovoltaic panels 200 slide and cross, the first brush plate 400 can brush the photovoltaic panel 200 below to brush the dust and impurities on the photovoltaic panel 200, that is, the passive cleaning of the photovoltaic panel 200 is realized by using the activity of the photovoltaic panel itself, and the active cleaning system of the photovoltaic panel can be omitted.

[0043] The second brush plate 410 is arranged above the ceiling 110, and the second brush plate 410 is above the sliding path of the uppermost group of photovoltaic panels 200 to brush the uppermost group of photovoltaic panels 200, and the bottom of the first brush plate 400 and the second brush plate 410 is provided with a brush structure 401 to brush the photovoltaic panel 200 sliding below it, and the brush structure 401 can be a brush, a scraping strip or the like. When the uppermost photovoltaic panel 200 passes through the second brush plate 410, the second brush plate 410 can brush the surface of the passing photovoltaic panel 200 to scrape the impurities and dust on the surface of the photovoltaic panel 200, thereby making up for the problem that the first brush plate 400 cannot brush the uppermost photovoltaic panel 200. Through the arrangement of the first brush plate 400 and the second brush plate 410, all photovoltaic panels 200 can be irradiated, and the relative movement between the upper and lower photovoltaic panels 200 can realize the cleaning of the photovoltaic panels 200, which can effectively reduce the frequency of manually or mechanically cleaning the photovoltaic panels 200 and reduce the cleaning and maintenance frequency.

[0044] Referring to Figure 6 In further embodiments of the present application, the first brush plate 400 comprises a horizontal plate 420 and a vertical plate 430, the vertical plate 430 extends in the sliding direction of the photovoltaic panel 200, and the vertical plate 430 is perpendicular to the horizontal plate 420 and arranged in the sliding direction of the photovoltaic panel 200, thereby avoiding the large area and weight of the first brush plate 400, and the arranged vertical plate 430 can realize multiple brushing in one stroke during brushing, thereby improving the brushing effect.

[0045] Referring toFigure 3 And Figure 7 In further embodiments of the present application, the upper end of the support frame 100 is provided with mounting plates 120 on both sides of the photovoltaic panel 200, and the mounting plates 120 are provided with sliding grooves 121 for the side edges of the photovoltaic panel 200 to be inserted and extend along the sliding direction of the photovoltaic panel 200, so as to guide and limit the sliding of the photovoltaic panel 200 by the sliding grooves 121, so that the sliding position of the photovoltaic panel 200 is accurate, and there is no collision between the upper and lower photovoltaic panels 200. It can be understood that the photovoltaic panels 200 in the same group are arranged in the left and right directions, and the mounting plates 120 correspondingly have a plurality of mounting plates arranged in the left and right directions.

[0046] Referring to Figure 3 , Figure 6 And Figure 7 In further embodiments of the present application, the photovoltaic panel 200 is provided with sliding bars 210 on both sides of the sliding groove 121, and the top wall, bottom wall and vertical outer wall of the sliding bar 210 are provided with rollers 211, and the vertical outer wall of the sliding bar 210, i.e. the outer wall of the sliding bar 210 facing away from the photovoltaic panel 200 and vertically, and the rollers 211 on the top wall, bottom wall and vertical outer wall are in rolling contact with the top wall, bottom wall and vertical side wall of the sliding groove 121, so as to change the sliding of the photovoltaic panel 200 into rolling, reduce the frictional resistance of the movement, and also leave a gap between the sliding groove 121 and the side edge of the photovoltaic panel 200. Even if the sliding groove 121 accumulates a small amount of impurities, it will not significantly hinder the sliding of the photovoltaic panel 200.

[0047] Referring to Figures 1 to 3 In further embodiments of the present application, the ceiling 110 is inclined upward from front to back, the front end of the sliding groove 121 is provided with a blocking block 122, and the rear end is provided with an opening, so that when installing, the photovoltaic panel 200 can be inserted from the rear end opening of the sliding groove 121, and the blocking block 122 at the front end of the sliding groove 121 can also prevent the photovoltaic panel 200 from tilting out of the sliding groove 121 and falling due to gravity when not controlled or damaged, and the blocking block 122 can effectively prevent the photovoltaic panel 200 from sliding out of the front end of the sliding groove 121, thereby improving the stability of the device.

[0048] Referring to Figure 1 And Figure 2In further embodiments of the present application, the top and bottom of the front and rear edges of the ceiling 110 are provided with pulley racks 130, the pulley racks 130 are provided with a plurality of pulleys 131, the plurality of pulleys 131 are staggered in the height direction to correspond to a plurality of groups of photovoltaic panels 200, the plurality of pulleys 131 are arranged outwardly inclined in a direction away from the ceiling 110, so that the pulleys 131 are staggered in the horizontal direction, the plurality of pulleys 131 on the pulley racks 130 on the same side are one-to-one corresponding, and all the center lines connecting the centers of the two pulleys 131 on the same side on the upper and lower pulley racks 130 are not intersected. The photovoltaic panels 200 are connected with pull ropes 220 at both ends, the pull ropes 220 are wound around the corresponding pulleys 131 and extend below the ceiling 110 and are connected with the sliding drive mechanism 300, the sliding drive mechanism 300 is used to wind and unwind the pull ropes 220 to pull the photovoltaic panels 200 to rotate. That is, the plurality of pulleys on the upper pulley rack 130 are arranged outwardly inclined in a direction from bottom to top, the plurality of pulleys on the lower pulley rack 130 are arranged outwardly inclined in a direction from top to bottom, and the plurality of pulleys on the front pulley rack 130 are gradually arranged away from the edge of the ceiling 110 in the front direction, the plurality of pulleys on the rear pulley rack 130 are gradually arranged away from the edge of the ceiling 110 in the rear direction. For example, the plurality of pulleys 131 on the upper pulley rack 130 on the front side are arranged outwardly inclined in a direction from bottom to top and in the front direction, so that the pulleys 131 gradually move away from the ceiling 110 in the front direction with the direction away from the ceiling 110, so that the pulleys all extend out of the edge of the ceiling 110 and the pulleys 131 on the same pulley rack 130 are staggered in the horizontal direction, so that the center lines of the plurality of pairs of pulleys 131 are not intersected, the pull ropes 220 wound around the two corresponding pulleys 131 do not intersect with the pull ropes 220 on other pulleys 131, so that the movements of the pull ropes 220 of the photovoltaic panels 200 at different heights do not interfere with each other. As shown in Figure 2 and Figure 4 The photovoltaic panels 200 are provided with three groups, each pulley rack 130 is provided with three pulleys 131, the upper and lower pulley racks 130 on the same side have six pulleys 131, there are three pairs of corresponding pulleys 131, and the two pulleys 131 in the same pair are used for the pull rope 220 of the corresponding photovoltaic panel 200 to be wound around, as shown in Figure 9 The upper and lower corresponding two pulleys 131 are vertically aligned. Thus, the pull rope 220 is wound around the ceiling 110 to be connected with the sliding drive mechanism 300 by using the upper and lower pulley racks 130. As shown in Figure 8As shown, the support frame 100 is vertically arranged with multiple mounting platforms 140 under the ceiling 110 for mounting the sliding drive mechanism 300 corresponding to different groups of photovoltaic panels 200. The sliding drive mechanism 300 is a rotary drive mechanism, such as a motor or a winch. For example, the sliding drive mechanism 300 can be a winch, and the pull rope 220 is connected to the winch. A winch can be provided corresponding to each photovoltaic panel 200. The pull ropes 220 at both ends of the photovoltaic panel 200 are wound on the drum of the winch, and the winding directions of the pull ropes 220 at both ends of the photovoltaic panel 200 are opposite. When the winch rotates in one direction, one pull rope 220 is tightened and the other pull rope 220 is unwound, thereby realizing the rotary drive of the photovoltaic panel 200. Of course, in other embodiments, a winch is separately provided corresponding to each pull rope 220 at both ends of the photovoltaic panel 200, and the winch is connected to the pull rope 220, thereby realizing independent control. Compared with the traditional telescopic drive mechanism such as a lead screw and a pneumatic cylinder, the driving mode of the rope, the pulley and the winch has a smaller size, and the arrangement position of the sliding drive mechanism 300 is more random, so that the photovoltaic panel 200 and the overall structure are more compact, and the ceiling can also shield and protect the sliding drive mechanism 300.

[0049] In addition, it can be understood that in other embodiments, the sliding drive mechanism 300 can also be other driving modes, such as a lead screw on the output shaft of the motor matched with the nut of the photovoltaic panel 200 to realize the sliding drive.

[0050] It can be understood that a group of photovoltaic panels 200 can be arranged in multiple numbers in the left-right direction, and the photovoltaic panels 200 in the same group can be controlled synchronously by the same set of sliding drive mechanisms 300, or each photovoltaic panel 200 can be independently controlled by the independently arranged sliding drive mechanism 300.

[0051] Referring to Figure 6 In further embodiments of the present application, the front and rear side edges of the photovoltaic panel 200 are provided with pull hanging holes 230 for connecting the pull rope 220, thereby facilitating the connection of the pull rope 220 and the photovoltaic panel 200. It can be understood that the outer side of the photovoltaic panel 200 is a metal frame structure, and the pull hanging hole 230 is arranged on the metal frame structure.

[0052] In some embodiments of the present application, the pulley bracket 130 is located on the sliding path of the photovoltaic panel 200 for limiting the sliding stroke of the photovoltaic panel 200. The pulley bracket 130 can be fixedly installed on the ceiling by fasteners. The pulley bracket 130 limits the photovoltaic panel 200 so that it does not completely leave the sliding groove 121. Especially when the sliding groove 121 is inclined upward toward the back, the pulley bracket 130 on the back side limits the sliding of the photovoltaic panel 200 toward the back, so that it does not move toward the back to leave the sliding groove 121 and fall off.

[0053] The above merely describes the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
