Background

The high-temperature weather in summer seriously affects the pig raising production, so that the feed intake of the pigs is reduced, the feed utilization rate is reduced, the growth speed is retarded, the pigs are dead, and the economic benefit of a pig farm is seriously affected. The heat inside and outside the pig body needs to be removed in a certain way, wherein the main heat dissipation modes comprise radiation heat dissipation, conduction heat dissipation, convection heat dissipation and evaporation heat dissipation. At present, radiation heat dissipation, conduction heat dissipation and convection heat dissipation in a high-temperature high-humidity environment cannot achieve a good effect on cooling of pigs, evaporation heat dissipation is an effective way for cooling of most animals, but the effect heat dissipation is not ideal for the pigs, and scientists propose various evaporation heat dissipation ways for enhancing the evaporation heat dissipation capacity of the pigs. For example, most pig farms adopt cascade fan system to cool down the colony house, and this mode has certain effect to the heat stress of alleviating the pig, but uses the cascade to cause the colony house humidity too high easily, causes the pig body to feel the high temperature, influences the growth state of pig.

There is the literature to disclose to spray water to pig body surface, only dispel the heat to the pig through the cooling mode that sprays, the temperature of face water often is less than pig body surface, pass to the aquatic with body surface temperature through the conduction mode and take away a partial heat of pig, the temperature of pig body surface is taken away in the evaporation of these moisture of on the other hand, use the fan to improve the evaporation that the wind speed can accelerate moisture, thereby reach the cooling effect, the experiment shows, the body surface temperature that the cooling can effectual reduction pig is sprayed, maintain the normal body of pig and feel the temperature, and the production efficiency is improved.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, but the following description of the embodiments is only for the purpose of helping understanding the principle and the core idea of the present invention, and is not intended to limit the scope of the present invention. It should be noted that modifications to the present invention may occur to those skilled in the art without departing from the principles of the present invention and are intended to fall within the scope of the appended claims.

Example 1

A fattening pig house is shown in figures 1, 2 and 3, and comprises an underground water pool 9, wherein the underground water pool 9 is positioned below the pig house, and is positioned 5-10 meters below the ground surface (the temperature of the position 5-10 meters below the ground surface is not changed along with the change of outdoor environment temperature, so that the water temperature in the underground water pool 9 is maintained at 15-17 ℃ throughout the year), a water spraying device 1 arranged at the top of the pig house and a spraying device 4 arranged in the pig house are arranged, and the water spraying device 1 and the spraying device 4 are respectively connected with the underground water pool 9.

In this embodiment, the eaves of the pigsty is provided with the water collecting tank 3, and the water collecting tank 3 is communicated with the underground water pool 9 through the backflow pipeline 5. A part of water sprayed from the water spraying device 1 on the top of the pigsty is evaporated, and the other part of water is recycled to the underground water pool 9 through the water collecting tank 3 and the return pipeline 5 for reuse.

In this embodiment, the return pipe 5 is provided with a filter 6, and the water replenishing pipe 16 is also provided with a filter 6.

In this embodiment, the water inlet pipes of the spraying device 4 and the water spraying device 1 are respectively provided with a voltage boosting stabilizer, and the voltage boosting stabilizer 8 on the water inlet pipe of the spraying device 4 is located on the vertical pipe section. The spray nozzle of the spray device 4 is positioned at the drinking side of the pigs in the pigsty, so that the other side is ensured to be dry, and the pigs can have lying rest.

Because the too big influence cooling effect of humidity in the pig house also causes easily to the persistence water spray, causes the waste of water simultaneously, consequently need calculate the water spray volume and the water spray time through the body surface area and the moisture evaporation efficiency of calculating every pig, the water spray is usually to spray water in the pig body table in the short time, and pig heat is taken away in the moisture evaporation of subsequent body surface. Under the normal condition, the water spraying amount of weaned pigs is 65 m/h/head, the water spraying amount of 100kg fattening pigs is 300mL per hour when the temperature is higher than 27 ℃, the water spraying amount is 1min, and the ventilation drying treatment is carried out for 29 minutes.

In this embodiment, the pig house lateral wall is provided with negative pressure ventilation portion 12, is provided with window 15 at the pig house lateral wall of negative pressure ventilation portion 12 offside, and window 15 department is provided with sliding baffle 14 and screen window, controls opening and shutting of window 15 through sliding baffle 14, adjusts the degree of opening and shutting of sliding baffle 14 and can control the amount of wind that gets into in the pig house, prevents the mosquito and fly through the screen window. The double-layer glass windows are arranged on the other two side walls of the pigsty, so that the pigsty is guaranteed to have sufficient illumination and simultaneously is insulated as far as possible.

In this embodiment, the bottom plate of pig house adopts slatted floor 7, is provided with the collection manure pit in the pig house below, is provided with in the collection manure pit and scrapes excrement device 13.

In this embodiment, water jet equipment 1 still includes the controller and sets up the temperature sensor at the pig house top, and when temperature sensor sensed the temperature and is higher than 30 ℃, water jet equipment 1 started the water spray, and when temperature sensor sensed the temperature and is less than 30 ℃, water jet equipment 1 closed.

In this embodiment, the aperture of the nozzle of the spraying device 4 is 100-300 μm. Because too big drop of water sprays the easy landing of pig body surface, the drop of water of undersize is vaporific is difficult for adhering to pig body surface, can spread in the colony house on the contrary, and these two kinds of circumstances all cause the interior humidity of pig house too high easily. The spray head with the head aperture of 100-300 mu m can reduce the waste of water on one hand, and can avoid the problem of overlarge humidity in the pigsty caused by excessive water spraying on the other hand, and meanwhile, the spraying time and the temperature need to be strictly controlled. In the use process, when the water level in the underground water tank 9 is lower than the warning line, the water is stored in time, and the water storage capacity of the underground water tank 9 is ensured to be sufficient.

The low-temperature water led out of the underground water pool from the pigsty cools the pigsty from the top of the pigsty on one hand, and sprays the pigs from the pigsty on the other hand, so that the body surface temperature of the pigs can be effectively reduced, the temperature of the pigsty can be effectively controlled, and the low-temperature water has an excellent cooling effect; this pig house both can realize the cyclic utilization of water resource, and the using water wisely can avoid too much water spray to lead to pig house humidity too big again, can also effectively improve pig body and feel the temperature.
