[0027] As shown in the drawings, a wet curtain cooling device comprises a wet curtain frame 1 and a core plate 2 fixedly installed inside the wet curtain frame 1. Figures 1-4

[0028] ​In this embodiment, the core board 2 is made of highly absorbent corrugated fiber paper or plastic, which has properties such as corrosion resistance and mildew resistance.

[0029] In this embodiment, the surface of the core plate 2 is formed with a large area of ​​honeycomb-shaped pores, which increases the contact area between air and cooling water and improves evaporation efficiency.

[0030] A pressure frame 3 is provided on each side of the wet curtain frame 1.

[0031] In this embodiment, the fixing structure between the pressure frame 3 and the core plate 2 (not shown in the figure) adopts common snap-on fixing structure, frame fitting fixing structure, bolt-reinforced fixing structure, etc., which are all existing technologies and will not be described in detail here.

[0032] Preferably, the pressure frame 3 is a rectangular frame, which is formed by two horizontal telescopic plates 31 and two vertical telescopic plates 32 connected end to end in sequence, and the horizontal telescopic plates 31 and the vertical telescopic plates 32 are perpendicular to each other.

[0033] In this embodiment, both the horizontal telescopic plate 31 and the vertical telescopic plate 32 include an intermediate plate, and a sliding plate is slidably installed at each end of the intermediate plate. The sliding plate can slide along the length of the intermediate plate to realize the adjustment of the length of the entire telescopic plate.

[0034] In this embodiment, the detailed structure and telescopic principle of the horizontal telescopic plate 31 and the vertical telescopic plate 32 constitute the prior art and are well known to those skilled in the art, and will not be described in detail here.

[0035] An adjustment mechanism is installed between the pressure frame 3 and the wet curtain frame 1. The adjustment mechanism is used to adjust the fixed dimensions of the pressure frame 3 in the height and width directions.

[0036] In this embodiment, the height and width of the pressure frame 3 are arbitrarily adjusted by the adjustment mechanism, so that the pressure frame 3 can seal and press the core board 2 of various sizes, thereby improving the applicability of this utility model.

[0037] like Figure 1 As shown, the adjustment mechanism includes a height adjustment component 4 and a width adjustment component 5. The height adjustment component 4 is installed between one end of the horizontal telescopic plate 31 and the wet curtain frame 1, and the width adjustment component 5 is installed between one end of the vertical telescopic plate 32 and the wet curtain frame 1.

[0038] In this embodiment, a height adjustment component 4 is provided at both ends of the horizontal telescopic plate 31, and similarly, a width adjustment component 5 is provided at both ends of the vertical telescopic plate 32.

[0039] In the embodiment, when the edge position of the core plate 2 is curled or the like, causing the cooling effect of the wet curtain to be greatly reduced, the worker can first dismount the core plate 2 and modify the edge thereof, then adjust the fixed size of the pressing frame 3 to a proper value through the adjusting mechanism, and then mount the core plate 2 into the wet curtain frame 1, so that the temporary emergency repair of the wet curtain is realized, so as to ensure that the cooling effect of the wet curtain can meet the minimum cooling requirement, and then the farm can customize a new wet curtain to replace the same.

[0040] As Figures 1-4 As shown in the drawings, the height adjusting assembly 4 and the width adjusting assembly 5 each include a first connecting rod 41, an intermediate connecting rod 42 and a second connecting rod 43 which are sequentially hingedly installed together, one end of the first connecting rod 41 away from the intermediate connecting rod 42 is hingedly installed on the side wall of the wet curtain frame 1, one end of the second connecting rod 43 away from the intermediate connecting rod 42 is hingedly installed on the pressing frame 3, and the adjusting screw rod 44 is jointly installed between the first connecting rod 41 and the second connecting rod 43.

[0041] In the height adjusting assembly 4, the upper end of the first connecting rod 41 is hingedly installed on the outer wall of the wet curtain frame 1, the lower end of the first connecting rod 41 is hingedly connected with the upper end of the intermediate connecting rod 42, the lower end of the intermediate connecting rod 42 is hingedly connected with the upper end of the second connecting rod 43, and the lower end of the second connecting rod 43 is hingedly installed on the outer wall of the horizontal telescopic plate 31.

[0042] In the width adjusting assembly 5, one end of the first connecting rod 51 is hingedly installed on the outer wall of the wet curtain frame 1, the other end of the first connecting rod 51 is hingedly connected with one end of the intermediate connecting rod 52, the other end of the intermediate connecting rod 52 is hingedly connected with one end of the second connecting rod 53, and the two segments of the second connecting rod 53 are hingedly installed on the vertical telescopic plate 32.

[0043] The adjusting screw rod 44 corresponding to the height adjusting assembly 4 extends along the width direction of the horizontal telescopic plate 31, the adjusting screw rod 44 is provided with two thread segments 45 with opposite screw directions, the nut seat 46 is threadedly installed on the thread segments 45, and the nut seat 46 is hingedly installed on the first connecting rod 41 and the second connecting rod 43 corresponding to the height adjusting assembly 4.

[0044] In the embodiment, when the height of the pressing frame 3 is adjusted by the height adjusting assembly 4: the adjusting screw rod 44 is rotated, the rotation of the adjusting screw rod 44 drives the two nut seats 46 on the adjusting screw rod 44 to move in the direction of approaching or moving away from each other, the movement of the nut seat 46 drives the first connecting rod 41 and the second connecting rod 43 to rotate synchronously, so that the first connecting rod 41 and the second connecting rod 43 are folded or stretched, thereby driving the two horizontal telescopic plates 31 to approach or move away from each other, and the two vertical telescopic plates 32 are elongated or contracted, so that the height of the pressing frame 3 is freely adjusted.

[0045] The adjusting screw 44 corresponding to the width adjusting component 5 extends along the width direction of the vertical telescopic plate 32. The adjusting screw 44 is provided with two threaded sections 45 with opposite spiral directions. Nut seats 46 are threadedly installed on the threaded sections 45. Nut seats 46 are hingedly installed on the first connecting rod 51 and the second connecting rod 53 corresponding to the width adjusting component 5.

[0046] In this embodiment, when adjusting the width of the pressure frame 3 using the width adjustment component 5: rotating the adjustment screw 44 causes the two nut seats 46 to move synchronously in the direction of approaching or moving away from each other. The movement of the nut seats 46 causes the first connecting rod 51 and the second connecting rod 53 to rotate synchronously, causing the first connecting rod 51 and the second connecting rod 53 to fold or extend, thereby causing the two vertical telescopic plates 32 to move closer or further away from each other, and the two horizontal telescopic plates 31 to extend or retract, thus realizing the free adjustment of the width of the pressure frame 3.

[0047] The adjusting screws 44 are all rotatably mounted on the mounting base 11 at the end near the wet curtain frame 1, and the mounting base 11 is fixedly mounted on the wet curtain frame 1.

[0048] In this embodiment, an adjustment handle is fixed to one end of the adjusting screw 44 that extends out of the mounting base 11, for rotating the adjusting screw 44.

[0049] The wet curtain frame 1 is provided with a sliding cavity 12, and one end of the pressure frame 3 extends into the sliding cavity 12 and is slidably connected to the wet curtain frame 1.

[0050] A water inlet cavity 13 is formed between the inner top wall of the wet curtain frame 1 and the top of the core plate 2, and a water distribution pipe 14 is installed inside the water inlet cavity 13.

[0051] A water outlet trough 15 is formed between the inner bottom wall of the wet curtain frame 1 and the bottom of the core plate 2. A circulating water pump (not shown in the figure) is installed between the water outlet trough 15 and the water distribution pipe 14.

[0052] In this embodiment, the inlet end of the water distribution pipe 14 is connected to a water tank for storing cooling water. A circulating water pump is installed between the outlet of the water tank and the water distribution pipe 14 to pump the cooling water in the water tank into the water distribution pipe 14. The inlet of the water tank is connected to the outlet trough 15 so that the cooling water in the outlet trough 15 can flow into the water tank for recycling.

[0053] Meanwhile, evaporators and condensers can be added to the cooling water recycling loop to ensure the low temperature of the cooling water.

[0054] The installation location and operating principle of the evaporator and condenser are existing technologies and will not be elaborated here.

[0055] In this embodiment, a negative pressure fan can be installed opposite the wet curtain to increase air circulation.

[0056] In this embodiment, the workflow for cooling the interior of the breeding shed using evaporative cooling pads is as follows:

[0057] The first step is to pump the cooling water in the water tank to the water distribution pipe 14 at the top of the wet curtain, and spray the cooling water onto the surface of the core board 2 through the evenly distributed nozzles or drip holes on the water distribution pipe 14.

[0058] The second step involves cooling water penetrating downwards along the capillary action of the corrugated fibers on the core plate 2, forming a uniform water film and ensuring that all pore surfaces are covered.

[0059] The third step is to start the negative pressure fan installed opposite the wet curtain, which creates negative pressure inside the breeding house. The high-temperature air outside is drawn in and forced through the wet curtain. During this process, the low-temperature water molecules contained in the water film come into full contact with the high-temperature air and evaporate.

[0060] The fourth step involves sending the cooled, humid air into the breeding shed through a negative pressure fan. After mixing with the hot air inside, the air is then exhausted from the breeding shed by the fan, creating a continuous cooling cycle inside the shed.

[0061] Fifth, the unevaporated cooling water flows back to the water tank through the water outlet 15 at the bottom of the wet curtain. After simple filtration and cooling, it is recycled again, realizing the efficient use of water resources.

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
