In one embodiment, the temperature-reducing device 30 contains hydrophilic groups in an amount such that the first contact angle θ of the temperature-reducing device 30 with water is achieved₁Less than 60 degrees, the hydrophilic group includes polyoxyethylene group, hydroxyl group, phenolic hydroxyl group, silicon hydroxyl group, carboxyl group, carboxylate group, amino group, alcohol amino group, amide group, alcohol amide group, quaternary ammonium group, zwitterion group, phosphate groupOne or more of sulfate group, sulfonic group and sulfonate group.

Referring to any one of fig. 2 to 4, fig. 2 to 4 respectively illustrate three different embodiments of the drainage cooling device 30. FIG. 2 is a schematic diagram illustrating the structure of an embodiment of a hydrophilic sheet sheared to form two drainage cooling devices 30; FIG. 3 is a schematic structural view showing a connection mode of the drainage cooling device 30 according to another embodiment; fig. 4 shows a schematic structural diagram of the drainage cooling device 30 and the film pressing rope 50 according to yet another embodiment. In one embodiment, the drainage cooling device 30 includes a plurality of drainage wires 31 and a connecting wire 32 connected to the plurality of drainage wires 31. The first hydrophilic surface is disposed on the drainage wire 31. The drainage wire 31 is arranged to cross the connection wire 32.

The crossing arrangement means that the drainage wires 31 and the connecting wires 32 cross each other when the drainage cooling device 30 is unfolded or installed on the cover 20. The crossing angle of the drainage wire 31 and the connecting wire 32 is not limited, and may be, for example, 90 ° or other angles.

It should be noted that the cross section of the drainage wire 31 perpendicular to the length direction thereof is, for example, circular, rectangular, triangular, pentagonal, hexagonal, etc., or the drainage wire 31 is in the form of a long strip, etc., and is not limited herein. Similarly, the cross section of the connecting wire 32 perpendicular to the length direction thereof is, for example, circular, rectangular, triangular, pentagonal, hexagonal, etc., or the connecting wire 32 is in the form of a long strip, etc., and is not particularly limited herein.

Specifically, the drainage wire 31 is fixedly connected to the connecting wire 32. Alternatively, the drainage wire 31 and the connecting wire 32 are fixedly connected at the crossing portion by means of adhesion, hot melt lamination, stitching, riveting or integral molding.

It should be noted that the connecting wire 32 is mainly used to connect a plurality of drainage wires 31 together, that is, the connecting position of the connecting wire 32 on the drainage wire 31 is not limited, and may be any position on the drainage wire 31.

Referring to fig. 2 and 3, as an example, the connecting wire 32 is connected to the upper end of the drainage wire 31, i.e. the expanded shape of the drainage cooling device 30 is comb-shaped.

Referring to fig. 4, in detail, the greenhouse 100 further includes a film pressing rope 50 disposed on the covering 20. When the greenhouse is used, for example, the connecting wires 32 are arranged between the covering 20 and the film pressing ropes 50, so that the drainage cooling device 30 is fully contacted with water on the covering 20, the surface tension of the water is damaged, and the water hidden in the concave part where the film pressing ropes 50 are contacted with the covering 20 is prevented from flowing to the ground on the side edge of the greenhouse 10 without being sucked and drained by the drainage wires 31. The lower ends of the diversion wires 31 extend out of the side edges of the shed frame 10 and extend to the preset area 40; two of the drainage wires 31 adjacent to the squeeze film string 50 straddle the squeeze film string 50. In this manner, water is drained from the cover 20 into the predetermined area 40.

Wherein, the upper end of the drainage wire 31 means that after the drainage cooling device 30 is installed on the covering 20, the end of the drainage wire 31 farthest from the ground, and the lower end of the drainage wire 31 means the end closest to the ground.

Referring to fig. 7 and 8, fig. 7 shows a schematic structural view of a drainage cooling device 30 and a hydrophilic drainage device 70 disposed on a cover 20 according to an embodiment of the present invention, and fig. 8 shows a schematic structural view of a drainage cooling device 30 and a hydrophilic drainage device 70 disposed on a cover 20 according to another embodiment of the present invention. Fig. 8 differs from fig. 7 in that the drain cooling device 30 illustrated in fig. 8 is, for example, two, and two drain wires 31 are arranged one above the other. In one embodiment, the drainage wire 31 and/or the connecting wire 32 and the squeeze film rope 50 are bound together by the binding member 33 at the contact part of the drainage wire 31 and/or the connecting wire 32 and the squeeze film rope 50. Specifically, the binding member 33 is, for example, a binding rope, a clamping member, an adhesive member, and the like, and can be selected according to actual requirements. Thus, the connecting wire 32 at the upper end of the drainage wire 31 can be stably attached to the surface of the cover 20, the connecting wire 32 is hardly separated from the cover 20 due to the pulling of the lower end, and water can be prevented from leaking to the ground at the side of the canopy frame 10 along the concave portions of the film pressing rope 50 and the cover 20.

Referring to fig. 4 and 5, fig. 5 is a schematic structural view illustrating the drainage cooling device 30 of fig. 4 mounted on the cover 20. In one embodiment, the drain cooling device 30 further includes a lower tie bar 34. The number of the connecting wires 32 is at least one, one connecting wire 32 is connected to the upper end of the drainage wire 31, and the lower ends of the drainage wires 31 are connected with the lower pull ribs 34. Thus, the lower pull ribs 34 stretch the drainage cooling device 30 to be straight, so that water flows along the drainage cooling device 30. It should be noted that the connecting wire 32 connected to the upper end of the drainage wire 31 is not limited to one, and may be two, three, four or more.

Referring to fig. 2, in one embodiment, the drainage wire 31 has a through hole 311 at the lower end thereof, and the lower pull rib 34 is inserted into the through hole 311. Thus, the lower tie bar 34 (e.g. the lower tie bar 34 shown in fig. 4 or fig. 5) can be sequentially inserted into the insertion hole 311 of the drainage wire 31, and the drainage cooling device 30 can be stretched by pulling the lower tie bar 34 downward. Wherein, the in-process that lower lacing bar 34 passed through every through-hole 311, lower lacing bar 34 for example can twist 90 degrees or penetrate behind the several multiples of 90 degrees around drainage silk 31, can make the gap (fretwork) between the drainage silk 31 change like this through lower lacing bar 34. So, make into canopy hot air and the water film layer contact distance of drainage silk 31 elongated, do benefit to aeration cooling.

Referring to fig. 4 or 5, in one embodiment, the lower tie bar 34 is tensioned at both ends and anchored to the ground anchor at both ends of the predetermined area 40; weights 62 such as bricks and stones are arranged on the lower lacing wires 34 at intervals, so that the drainage cooling device 30 is transversely and longitudinally tightened. The weights 62 are connected to the lower pull rib 34 by, for example, a weight string 63, and the number of the weights 62 is not limited and may be set according to actual needs.

In one embodiment, the drain cooling device 30 can be laid upside down on the cover 20, i.e.: laying the connecting wire 32 on the preset area 40; the lower tie bar 34 is disposed between the cover 20 and the squeeze film string 50 and passes through the insertion hole 311.

In one embodiment, the material of the lower pull ribs 34 includes: the curtain supporting line, the vine hanging rope, the tearing rope, the strip-shaped film pressing line, the circular film pressing line, the galvanized iron wire, the plastic-coated iron wire, the stainless steel wire, the steel wire rope, the wooden stick bamboo pole or the steel pipe and the like can be selected according to actual requirements, and are not limited.

Referring to fig. 3, it can be understood that, in the process of fixedly connecting the connecting wire 32 and the drainage wire 31 together, in order to ensure that the connecting wire 32 and the drainage wire 31 are stably connected, as an example, the connecting wire 32 is crosswise arranged at a certain position of the drainage wire 31, and then the end of the drainage wire 31 is reversely folded, so that the drainage wire 31 is distributed at two sides of the connecting wire 32, that is, at least two positions of the drainage wire 31 and the connecting wire 32 are in contact with each other, and the at least two positions are connected by a fixed connection manner such as adhesion, hot melt compounding, sewing or riveting, so that the fixed connection between the drainage wire 31 and the connecting wire 32 is firmer.

It should be noted that the certain part can be any position on the drainage wire 31, for example, the middle position of the drainage wire 31, so that the drainage wire 31 is folded in half and then fixedly connected with the connecting wire 32, and the drainage cooling device 30 laid in two layers is formed, and has a better drainage cooling effect; of course, other positions of the drainage wire 31 are also possible, and are not limited herein, and may be set according to actual requirements.

In one embodiment, the number of the connecting wires 32 is not limited to one, and may also be two, three, four or more, and two adjacent drainage wires 31 and two adjacent connecting wires 32 intersecting with the drainage wires define a void (not shown in the figure), the void is permeable to high temperature air, and a water film formed on the surface of the drainage wire 31 can better reduce the temperature of the high temperature air.

In one embodiment, the connecting wire 32 includes a first connecting wire 321 disposed at an upper end of the drain wire 31 and a second connecting wire 322 disposed at a lower end of the drain wire 31. The adjacent two drainage wires 31 and the first connecting wire 321 and the second connecting wire 322 enclose an aperture.

When the film pressing device is used specifically, according to the position of each film pressing rope 50, the second connecting wires 322 are sequentially cut at the corresponding positions aligned with each film pressing rope 50, and a plurality of first cut 3221 are formed; and the first connecting wire 321 is laid between the covering 20 and the film pressing rope 50, each drainage wire 31 is pulled out of the side edge of the shed 10, and the drainage wires 31 at the two sides of the first cut 3221 straddle the two sides of the corresponding film pressing rope 50. And then the lower lacing wires 34 are inserted into the lower edges of the holes defined by the fixed connection of the second connecting wires 322 and the drainage wires 31, so that the drainage cooling device 30 can be stretched and straightened through the lower lacing wires 34. Thus, the second connecting wires 322 connected and arranged at the lower ends of the drainage wires 31 can avoid messy knotting of the drainage wires 31; and the lower pull ribs 34 do not need to be threaded around each drainage wire 31, and only need to be threaded in a plurality of holes between two adjacent first shearing mouths 3221 for a few times, so that the laying and installation labor amount is remarkably reduced, and the laying and installation efficiency is remarkably improved. In addition, at the overlapped part of the drainage cooling device 30 and the film pressing rope 50, each connecting wire 32 extending out of the film pressing rope 50 is sequentially cut off, so that the lower part of the drainage cooling device 30 can be pulled out of the greenhouse and extended to the preset area 40. Because the connecting wire 32 is fixedly connected with the drainage wire 31, the first cut 3221 is not disconnected, thereby substantially avoiding influencing the longitudinal tensile strength of the drainage cooling device 30.

Further, a third connecting wire 323 is provided between the first connecting wire 321 and the second connecting wire 322. As in the above embodiment, the first connecting wire 321 may be disposed between the film pressing rope 50 and the covering 20, and the second connecting wire 322 and the third connecting wire 323 may be cut to extend out of the side of the canopy frame 10 to be laid in a single layer; or the third connecting wire 323 is arranged between the film pressing rope 50 and the covering 20, the first connecting wire 321 and the second connecting wire 322 are cut off and hang down to extend out of the side edge of the shed frame 10, and the double-layer laying is carried out.

Referring to fig. 4, the specific structural form of the drainage wire 31 is set according to actual requirements, and is not limited herein. As an example, the drainage wire 31 is a single wire or two wires, etc., and for example, the drainage wire 31 is formed by connecting a plurality of drainage wire segments in series. In one embodiment, different drainage wire segments may be disposed above and below the third connecting wire 323, the interfaces between the drainage wire segments are located on the third connecting wire 323, and the interfaces may be overlapped, leveled, staggered, or form a fracture; the water falls from the section of the drainage wire above the third connecting wire 323, through the third connecting wire 323, and onto the section of the drainage wire below the third connecting wire 323. In one embodiment, a plurality of the discharge wire segments can also be connected in parallel or in series.

As an optional scheme, the through holes 311 do not need to be arranged on the drainage wire 31, but a plurality of through holes 311 are arranged on the second connecting wire 322, the lower tie bars 34 sequentially pass through the through holes 311, the lower tie bars 34 are tightened, and the drainage cooling device 30 can also be stretched flat.

As an alternative, when the drain cooling device 30 is mounted on the cover 20 in an inverted position, the first connecting wires 321 and the second connecting wires 322 can be arranged in an inverted position.

In one embodiment, two sides of the upper end of the drainage wire 31 are fixedly connected with one connecting wire 32, that is, two connecting wires 32 are fixedly connected with the upper end of the drainage wire 31 to form a 'three-ply board' structure. Similarly, both side surfaces of the lower end of the drainage wire 31 are fixedly connected with a connecting wire 32, that is, the two connecting wires 32 are fixedly connected with the lower end of the drainage wire 31 to form a three-ply board structure. Therefore, the connection part of the drainage wire 31 and the connecting wire 32 is stable and not easy to break. Of course, in order to further enhance the structural stability of the joint of the drainage wire 31 and the connecting wire 32, the top end of the drainage wire 31 can be folded reversely and clamped outside the connecting wire 32 on one side to form a four-ply board structure; the connecting wires 32 can be supplemented, and the diversion wires 31 can be folded reversely again to be fixedly connected to form a 'five-ply board' structure, a 'six-ply board' structure and the like; the specific connection mode of the connecting wire 32 and the drainage wire 31 and the selected combination number can be set according to actual requirements, and are not limited herein. Or two drainage wires 31 which are closed together, the upper ends of the drainage wires are tightly clamped between the two connecting wires 32 to form a four-ply board structure; and the lower extreme centre gripping respectively forms two sets of "three ply board" structures between two sets of respectively two relative connecting wire 32 that set up to fixed connection forms the drainage heat sink 30 that is used for double-deck stack to lay. Or the upper ends of the two drainage wires 31 are arranged between the two connecting wires 32 side by side to form two tandem three-ply boards; the lower extreme centre gripping respectively forms two sets of "three ply board" structures between two sets of each two relative connecting wire 32 that set up to fixed connection forms the drainage heat sink 30 that is used for double-deck stack to lay. In the same way, the drainage cooling device 30 with three layers of layers, four layers of layers and the like can be fixedly connected.

In this embodiment, because the connecting wire 32 is fixedly connected with the drainage wire 31, the required length of the drainage cooling device 30 can be arbitrarily cut according to the length of the greenhouse 100, which is convenient for standardized production with uniform specification. The partial drainage cooling device 30 longer than the greenhouse can be folded back to form a partial double-layer structure.

As an example, multiple induced-cooling devices 30 can be used in series, parallel, or series-parallel on the same greenhouse 100. Namely: a plurality of the drainage cooling devices 30 can be spliced and used in parallel on the same greenhouse 100; or, a plurality of drainage heat sink 30 also can set up on covering 20 superposedly, and two adjacent laminated drainage heat sink 30 are equipped with the layer clearance, can be used for the drainage of the great water of flow, and successive layer evaporation and heat exchange cooling advance the canopy hot-air and cool down step by step between the layer.
