Description

Technical Field

[0001] The utility model relates to the field of agricultural photovoltaic planting, in particular to a water collection structure for photovoltaic modules in an integrated agricultural and photovoltaic plant factory type. Background Art

[0002] In the current practice of agricultural-photovoltaic complementary projects, to maximize land use efficiency and ensure dual outputs of energy and agriculture, organized large-scale crop planting is carried out under photovoltaic arrays.

[0003] However, this layout poses specific challenges under rainfall conditions: when rain falls, it flows downward along the vertical spacing between photovoltaic panels, forming water droplets that directly drip onto the crops below. This non-uniform and difficult-to-control drip irrigation method interferes with the precise regulation of conventional irrigation systems, making the crops likely to encounter overwatering or local overwetness, which is not conducive to maintaining appropriate soil moisture and the health of crop roots; if the crops are fertilized with nutrient solution, the rainwater dripping will mix with the nutrient solution, resulting in a change in the originally carefully formulated nutrient solution concentration. The diluted nutrient solution may not meet the specific nutrient ratio required for crop growth, affecting its normal metabolism and yield. Frequent rainwashing may also cause the loss of some nutrient elements, increasing the complexity and cost of fertilizer management; long-term and concentrated exposure to the rain impact dripping from the gaps between photovoltaic panels may cause physical damage to the ground in the planting area. The continuous impact force of rainwater may cause the surface structure of the soil to become loose, leading to soil erosion, affecting soil air permeability, water retention capacity and fertility, and thus affecting crop root growth and overall yield. In addition, the increase in surface runoff may also erode field roads and other infrastructure. Therefore, a water collection structure for photovoltaic modules in an integrated agricultural and photovoltaic plant factory type is proposed to solve the above problems.

Detailed implementation mode

[0029] As Figures 1-11 shown, a water collection structure for photovoltaic modules in an integrated agricultural and photovoltaic plant factory type includes a multi-span greenhouse 1 (or a simple plant factory based on a photovoltaic project). The multi-span greenhouse 1 is composed of multiple greenhouse units 11 and a water collection trough unit 12 arranged between the arches of multiple greenhouse units 11. The characteristics are as follows: The greenhouse unit 11 includes a support frame 110. The water collection trough unit 12 is arranged on the outermost two rows of support columns of the support frame 110. A conical support main frame 111 is arranged at the top of the support frame 110. Both ends of the conical support main frame 111 are connected to the water collection trough unit 12. In this embodiment, the support frame 110 is composed of three rows of support columns. The conical support main frame 111 is erected on the three rows of support columns. The conical support main frame 111 is composed of a cross bar, a vertical bar and a diagonal brace, and its top forms a cone, meeting the support conditions of the photovoltaic module 112 and the covering conditions of the plastic film. The water collection trough unit 12 is fixed between the support columns and the conical support main frame 111 by bolts.

[0030] A photovoltaic module 112 is arranged on the inclined surface on one side of the conical support main frame 111, and a transparent film 113 is arranged on the inclined surface on the other side. The transparent film 113 is a plastic film. The separated ends of the photovoltaic module 112 and the transparent film 113 are both connected to the water collection trough unit 12. The transparent film 113 can seal the gap between each column of photovoltaic modules 112 to prevent rainwater from dripping onto the crops planted below, and at the same time, the transparent plastic film will not affect its normal lighting condition. The inclined photovoltaic module 112 and transparent film 113 can guide rainwater into the water collection trough unit 12, so as to realize the diversion of rainwater by using the water collection trough unit 12.

[0031] In this embodiment, the photovoltaic modules 112 are continuously laid, and waterproof treatment is performed at their joints.

[0032] The water collecting tank unit 12 includes a tank body 121. Drain pipes 122 are communicatively arranged at both ends of the tank body 121, and the drain pipes 122 discharge the water in the tank body 121. Folding plates 123 and docking grooves 126 are respectively arranged along the upper edges of the left and right side plates of the tank body 121. The transparent film 113 extends along the folding plate 123 into the angle between the folding plate 123 and the side plate of the tank body 121. A plurality of clamping assemblies 124 for fixing the transparent film 113 are arranged outside the folding plate 123. The docking groove 126 is used to dock the bottom edge of the photovoltaic module 112. The folding plate 123 and the docking groove 126 facilitate the connection of the tank body 121 to the transparent film 113 and the photovoltaic module 112, enabling rainwater to flow smoothly into the tank body 121.

[0033] It should be noted that the tank body 121 can be integrally formed or assembled by fixing multiple segments with bolts. In addition, a transparent film 113 for enclosing the multi-span greenhouse 1 can be arranged around the perimeter.

[0034] In a preferred embodiment, the clamping assembly 124 includes two symmetrically arranged clamping plates 1241. One end of the two clamping plates 1241 is connected by a first soft rubber 1242, enabling the two clamping plates 1241 to adjust the spacing at will. After the transparent film 113 is folded into the angle between the folding plate 123 and the tank body 121, the two clamping plates 1241 are clamped on the upper and lower sides of the folding plate 123, and the transparent film 113 is fixed by the clamping of the two folding plates 123. A plurality of threaded counterbore holes 1243 close to the first soft rubber 1242 are arranged on the upper clamping plate 1241. A clamping stop lock 1245 is threadedly installed in the threaded counterbore holes 1243. A stop lock hole 1244 corresponding to the threaded counterbore holes 1243 is arranged on the other clamping plate 1241. A plurality of stop lock catches 1246 are arranged on the inner wall surface of the stop lock hole 1244. In this embodiment, two groups of stop lock catches 1246 are arranged, and the number of each group of stop lock catches 1246 is not less than two, and they are annularly and equidistantly distributed on the inner wall surface of the stop lock hole 1244. The end of the clamping stop lock 1245 passes through the stop lock hole 1244 and is engaged with the stop lock catches 1246, thereby locking the spacing between the two clamping plates 1241.

[0035] Among them, the clamping lock 1245 includes a screw 1247 threadedly connected to the threaded counterbore 1243. An integrally formed insertion rod 1248 is connected to the end of the screw 1247. A plurality of trapezoidal locking rings 1249 are arranged outside the insertion rod 1248. The diameters of the insertion rod 1248 and the trapezoidal locking rings 1249 are smaller than the diameter of the screw 1247, facilitating the smooth passing of the insertion rod 1248 and the trapezoidal locking rings 1249 through the threaded counterbore 1243. The locking buckle 1246 includes a trapezoidal block adapted to the trapezoidal locking ring 1249. The inclined surfaces of the trapezoidal locking ring 1249 and the trapezoidal block are arranged in parallel. A connecting block connected to the inner wall surface of the locking hole 1244 is arranged at the end of the trapezoidal block. A gap for contraction is reserved between the trapezoidal block and the inner wall surface of the locking hole 1244. When the insertion rod 1248 is inserted into the locking hole 1244, the trapezoidal locking ring 1249 contacts the trapezoidal block through the inclined surface, causing the trapezoidal block to expand and contract under the action of the gap, enabling the trapezoidal locking ring 1249 to pass through the locking buckle 1246. Then, the locking effect is achieved by the straight edges where the trapezoidal locking ring 1249 and the trapezoidal block are in contact. Thus, when locking, it is only necessary to relatively press the two clamping plates 1241. The arrangement of a plurality of trapezoidal locking rings 1249 can achieve the effect of locking different spacings.

[0036] In a preferred embodiment, a plurality of corresponding through holes 1250 are further provided on the two clamping plates 1241. A screw nut 1251 is penetrated through the through holes 1250, and the clamping assembly 124 can be further locked by using the screw nut 1251.

[0037] In a preferred embodiment, end plates are provided at both ends of the groove body 121. The end plates seal both ends of the groove body 121. A notch 125 is provided at the upper edge of the side plate of the groove body 121. Hinge holes 1211 are provided on the end plates at the positions of the notches 125. Rotating shafts 1261 rotatably connected to the hinge holes 1211 are provided at both ends of the docking groove 126. Thus, the docking angle of the docking groove 126 can be adjusted by rotating the docking groove 126 in the notch 125 to adapt to the laying angle of the photovoltaic module 112. In this embodiment, the groove body length of the docking groove 126 is adapted to the laying length of the photovoltaic module 112. In addition, a sealing ring can be provided at the docking position between the photovoltaic module 112 and the docking groove 126 to achieve a sealing effect.

[0038] In a preferred embodiment, arc-shaped chutes 1212 are provided on the inner sides of the end plates. Sliders 1262 slidably connected to the arc-shaped chutes 1212 are provided at both ends of the docking groove 126. By using the sliding of the sliders 1262 in the arc-shaped chutes 1212, the stability of the docking groove 126 during rotation is improved.

[0039] In a preferred embodiment, a second soft rubber 127 is provided between the tail of the docking groove 126 and the upper edge of the side plate. The reserved length of the second soft rubber 127 adapts to the rotation angle of the docking groove 126, thereby sealing the notch 125 through the second soft rubber 127.

[0040] In a preferred embodiment, a road photovoltaic greenhouse 2 is arranged on the road with a row spacing between multiple multi-span greenhouses 1. The road photovoltaic greenhouse 2 has the same structure as the multi-span greenhouse 1. The road photovoltaic greenhouse 2 can protect the road between multiple multi-span greenhouses 1, prevent the road from being damaged by rainwater, and at the same time increase the laying area of the photovoltaic modules 112. The support structure of the road photovoltaic greenhouse 2 is set according to the width of the road.

[0041] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
