Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of breeding, and in particular to a ventilation and cooling device for a cattle shed. Background Art
[0002] In terms of cattle house management in breeding technology, maintaining good ventilation and appropriate cooling measures is one of the most important maintenance measures, which is not only related to the health and well-being of cattle, but also directly affects the economic benefits of breeding. In warm or hot seasons, cattle will generate a lot of heat, especially under high-density breeding conditions. Cows are close to each other and their body heat is superimposed on each other, causing the temperature in the cattle house to rise rapidly. The high temperature environment will increase the heat stress of cattle, causing their metabolism to accelerate, breathing to increase, and feed intake to decrease, which in turn affects the milk production of dairy cows and the growth rate of beef cattle. In severe cases, it may also cause heat stroke, endangering the lives of cattle.
[0003] At present, in economical cattle farms, ventilation and cooling measures usually adopt an open cowshed combined with fans to cool the cattle. Fans are installed in the cowshed, and the strong wind flow generated by the wind accelerates the evaporation of sweat on the surface of the cattle, thereby taking away the heat. However, cattle will feel uncomfortable if they are directly exposed to the wind for a long time, and may even develop respiratory problems such as colds, which will affect the health of the cattle. How to invent a cowshed ventilation and cooling device to improve these problems has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

[0021] Example, see Figure 1-Figure 3 A cowshed ventilation and cooling device comprises a base 1, a water storage tank 6 and a plurality of vertical frames 2 are fixedly connected to the top of the base 1, a cowshed roof 3 is fixedly connected to the top of the cowshed roof 3, a plurality of water blocking plates 4 are fixedly connected to the top of the cowshed roof 3, a sunshade layer 5 is fixedly connected to the top of the plurality of water blocking plates 4, the sunshade layer 5 blocks sunlight to prevent the temperature of the cowshed roof 3 from rising rapidly under direct sunlight, a water spray pipe 7 is fixedly connected to the top of the cowshed roof 3, one end of the water spray pipe 7 is sleeved with a water pump 8, the other end of the water spray pipe 7 is closed, and the water pump 8 is fixedly connected to the water blocking plate 4, A water pipe 9 is fixedly connected to the bottom of the water spray pipe 7, and the water pipe 9 is connected to the water spray pipe 7. A cooling structure is arranged on the lower side of the cowshed roof 3. A plurality of water spray holes 10 are opened on the outer wall of the water spray pipe 7. The water spray holes 10 are arranged on both sides of the water spray pipe 7. The water spray holes 10 correspond to the cowshed roof 3, so that the water flow evenly covers the surface of the cowshed roof 3. After the water pump 8 pumps water into the water spray pipe 7, it is sprayed onto the top of the cowshed roof 3 from the water spray holes 10. The water flows on the surface of the cowshed roof 3, and continuously evaporates to take away the heat on the cowshed roof 3, so that the temperature of the cowshed is always lower than the outside temperature.
[0022] Reference Figure 1-Figure 5The cooling structure includes a ventilation pipe 11, which is fixedly connected to the bottom of the cowshed roof 3 through a first bracket, a water pipe 9 is connected to the ventilation pipe 11, and a motor 12 is fixedly connected to the inner wall of the ventilation pipe 11 through a second bracket. The output end of the motor 12 is sleeved with a fan blade, and a water absorption net 13 is fixedly connected to the inner wall of the ventilation pipe 11. The water absorption net 13 uses a water-absorbing material to keep the inside of the mesh moist, providing a precondition for water vapor cooling. The water absorption net 13 is located directly below the water pipe 9, and the ventilation pipe 1 1 is fixedly connected to the outer wall of the cowshed 1, and the multiple air expansion ports 14 are connected to the ventilation pipe 11. A return pipe 15 is fixedly connected to the bottom of the ventilation pipe 11, and the return pipe 15 is connected to the ventilation pipe 11. The multiple air expansion ports 14 are evenly distributed on both sides of the ventilation pipe 11, and the air expansion ports 14 are arranged in a trumpet shape, so that the wind blown out of the ventilation pipe 11 is blown in a diffused manner, which is more gentle. The bottom of the cowshed top plate 3 is fixedly connected to multiple return pipes 16, and the return pipes 16 are connected to the cowshed top plate 3. The bottoms of multiple return pipes 16 and return water pipes 15 are connected and communicated through a collecting pipe 17. The collecting pipe 17 is fixedly connected to the water storage tank 6 and communicated. The water in the water spray pipe 7 is absorbed by the water absorption net 13. The fan blades driven by the motor 12 blow the wind through the gaps in the water absorption net 13, and blow the wind containing water vapor into the ventilation pipe 11 and blow it out from the air expansion port 14. The gentler wind blows the water vapor to the surface of the cattle's body. The evaporation of the water vapor takes away the heat from the surface of the cattle's body, preventing the cattle from catching a cold or other respiratory problems due to being directly blown by the strong wind from the fan.
[0023] The working principle of the ventilation and cooling device for a cowshed is as follows: in summer, the temperature of the top of the cowshed rises due to direct sunlight. The cowshed roof 3 is protected from direct sunlight by the sunshade layer 5. The water pump 8 is started to inject water into the water spray pipe 7. The water in the water spray pipe 7 is sprayed from the water spray hole 10 to the top of the cowshed roof 3 under the action of pressure. The water flow continues to flow and evaporates to take away the heat of the cowshed roof 3. The water in the water spray pipe 7 also flows into the ventilation pipe 11 through the water pipe 9 and is absorbed by the water absorption net 13. The motor 1 is started. 2. The motor 12 drives the fan blades to blow air in the direction of the water absorption net 13. The wind passes through the gap of the wet water absorption net 13, blows into the ventilation pipe 11 with a large amount of water vapor, and blows to the cattle below through the air expansion port 14. The water vapor evaporates and takes away the heat from the surface of the cattle body. The water used for cooling on the top of the cowshed roof 3 flows into the collecting pipe 17 through the return pipe 16, and the excess water inside the ventilation pipe 11 flows into the collecting pipe 17 through the return pipe 15. The water in the collecting pipe 17 flows into the water storage tank 6 to complete the collection of water flow.
[0024] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0025] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
