Description

Technical Field

[0001] The utility model relates to the technical field of beef cattle breeding, in particular to a cattle shed ventilation and cooling device for beef cattle breeding. Background Art

[0002] Temperature has a great impact on beef cattle production. High humidity environment will aggravate the impact of high temperature on cattle. In summer, when the temperature inside the house or shed is higher than that outside the house, ventilation can bring the heat inside the house or shed out of the house, and can also increase the speed of air flow inside the house or shed. When passing through the body of beef cattle, it takes away the dissipated heat and promotes the evaporation and heat dissipation of the beef cattle.

[0020] Reference Figure 1-3A ventilation and cooling device for a cattle shed for beef cattle breeding comprises a cattle shed 1, wherein the cattle shed 1 is composed of a floor 1-1, a plurality of support columns 1-2 and a shed roof 1-3, wherein the cross section of the shed roof 1-3 is in a herringbone shape, with both sides inclined downward, and the shed roof 1-3 is arranged parallel to the top of the floor 1-1, and the plurality of support columns 1-2 are evenly divided into two groups, wherein the plurality of support columns 1-2 in each group are arranged in a straight line and equidistantly, and the two groups of support columns 1-2 are symmetrical to each other, and the top ends of the plurality of support columns 1-2 are respectively fixedly installed on both sides of the lower end of the shed roof, and the lower ends of the plurality of support columns 1-2 are fixedly connected to the floor 1-1, and a vent is formed between every two adjacent support columns 1-2 on both sides and the floor 1-1 and the shed roof 1-3;

[0021] In this embodiment, a plurality of strip slits 1-4 are provided at the edges of both sides of the roof 1-3, and the plurality of strip slits 1-4 are respectively provided directly above the plurality of vents, and a water retaining frame 4 is fixedly installed on the upper end surface of the outer circle of the roof 1-3, and the water retaining frame 4 is used to retain the water above the roof 1-3 on the edges of both sides of the roof 1-3, that is, the water above the roof 1-3 is gathered above the plurality of strip slits 1-4 through the water retaining frame 4.

[0022] In this embodiment, a strip groove body 2 is fixedly installed in the middle of the water retaining frame 4, and the strip groove body 2 is fixedly installed at the middle end protrusion of the roof 1-3. A number of densely and evenly arranged drainage holes 3 are provided at the lower end edges on both sides of the strip groove body 2, and the drainage holes 3 and the lower end of the inner cavity of the strip groove body 2 are connected to each other.

[0023] In the present embodiment, a mesh curtain 5 is provided in each of the strip slits 1-4, and the upper end of the mesh curtain 5 is fixedly installed in the strip slits 1-4. The lower part of the mesh curtain 5 is used to block the vents below, which can provide sunshade and heat insulation to prevent the beef cattle raised in the cowshed 1 from being directly exposed to the sun on sunny days. A plurality of densely distributed small holes are provided on the mesh curtain 5. The plurality of densely distributed small holes are used for light transmission and for easily forming a water film to increase the surface area of ​​clean water, thereby increasing the evaporation rate of the clean water and utilizing the evaporation absorption of the clean water to absorb heat and cool down. The mesh curtain 5 in the present application specifically adopts a bamboo curtain.

[0024] It should be added that the present application also needs to utilize the water pump in the prior art to extract clean water and stably transport it to the inner cavity of the strip trough body 2, so as to stably maintain a certain height of clean water in the inner cavity of the strip trough body 2, and the clean water accumulated in the strip trough body 2 flows out at a uniform speed through a number of drainage holes 3, and gathers at the two side edges of the roof 1-3 along the inclined surfaces on both sides of the roof 1-3, and guides the clean water to flow downward along the mesh curtains 5 in the strip seams 1-4 to form a water curtain, and forms a water film on both sides of the several small holes in the mesh curtains 5, and when the clean water flows through the roof 1-3, the roof 1-3 can also form a water curtain with the clean water flowing downward, accelerate the evaporation of the clean water, and cool the roof 1-3.

[0025] In this embodiment, fans 6 are arranged between the mesh curtains 5 on both sides. The upper ends of the fans 6 are fixedly installed under the ceiling 1-3 through hangers. The air outlets of the fans 6 and the mesh curtains 5 are parallel to each other. The fans 6 are connected to an external power supply through wires.

[0026] It is further supplemented that the several mesh curtains 5 in the present application are respectively arranged on the north and south end surfaces of the cowshed 1, that is, one side of the several mesh curtains 5 faces the sun and the other side faces the shade. When the sun shines on the several mesh curtains 5 facing the sun and the roof 1-3, the sun can accelerate the evaporation and absorption of clean water on the roof 1-3 and the several mesh curtains 5 facing the sun, and the air outlet of the fan 6 faces the mesh curtain 5 facing the sun, that is, the several fans 6 are used to extract cool air on the shady side through the several mesh curtains 5 on the shady side, and blow the air in the cowshed 1 to the several mesh curtains 5 on the sunny side, thereby driving the gas to pass through the water film formed on the mesh curtain 5, accelerating the evaporation of the water film and absorbing heat and cooling, and reducing the temperature around the cowshed 1.

[0027] The utility model firstly forms a water curtain on the roof 1-3 and a plurality of mesh curtains 5. The water curtain increases the surface area of ​​clean water, accelerates the evaporation and heat absorption of clean water around the cowshed 1, thereby realizing cooling of the area around the cowshed 1 by the water curtain, and then draws the air cooled by the water curtain into the cowshed 1 for air cooling through the fan 6. When the fan 6 is working, it can also accelerate the air to pass through the small holes of the mesh curtain 5 to form a water film, accelerate the evaporation of the water film, and accelerate the cooling of the cowshed 1. That is, the evaporation of the water curtain formed on the roof 1-3 and the plurality of mesh curtains 5 and the acceleration of air circulation by the fan 6 assist each other, and the cooling effect is better.
