Description

Technical Field

[0001] The utility model relates to the technical field of temperature control of cattle sheds, in particular to a cooling system for air inlets of cattle sheds. Background Art

[0002] Tunnel ventilation cowshed is a new type of livestock building. It improves the air quality of the living environment of cattle by building a tunnel ventilation system under the cowshed. Tunnel ventilation cowshed generally installs a tunnel fan on the gable at one end, and the other end is set as an air inlet. The fan generates negative pressure, so that the air flow is sucked into the cowshed from the air inlet. The air inlet of the cowshed is usually equipped with a wet curtain to cool the air in the cowshed. When the air flows through the moist curtain, the water evaporates and absorbs heat, resulting in an increase in air temperature. The cooled air is transported to the inside of the cowshed by negative pressure, forming a longitudinal tunnel ventilation belt along the cowshed, and finally discharged by the fan. This can provide fresh air for the cows, and make full use of the air flow rate, reduce the surface temperature of the cows, reduce the heat stress reaction of the cows, and improve the growth efficiency and milk production of the cows.

[0031] The terms used in the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "the" and "said" used in the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0032] Tunnel-ventilated cowsheds usually have tunnel fans installed on the gable at one end, and the other end is set as an air inlet. The fan generates negative pressure, so that the air flow is sucked into the cowshed from the air inlet. The air inlet of the cowshed is usually equipped with a wet curtain to cool the air in the cowshed. When the air flows through the moist curtain, the water evaporates and absorbs heat, resulting in a high air temperature. The cooled air is transported to the inside of the cowshed by negative pressure, forming a longitudinal tunnel ventilation belt along the cowshed, and finally discharged by the fan. This can provide fresh air for the cows, and make full use of the air flow rate, reduce the surface temperature of the cows, reduce the heat stress reaction of the cows, and improve the growth efficiency and milk production of the cows.

[0033] However, the wet curtain has a short service life and high maintenance cost, and the curtain pieces are prone to moss growth, thereby blocking the air inlet, resulting in poor ventilation and cooling effects in the cowshed, affecting the growth of cattle. Based on this, the present application provides a cooling system for the air inlet of a cowshed.

[0036] A spray device, wherein the spray device comprises a plurality of spray pipes 2, each of which is movably arranged on the top of the cowshed 1, and each of which is provided with a plurality of atomizing nozzles 21, and each of which is arranged toward the air inlet 11 of the cowshed 1;

[0037] The cold water supply device comprises a water chiller 4 and a pressure pump 3 , the water outlet of the water chiller 4 is connected to the water inlet of the pressure pump 3 , and the water outlet of the pressure pump 3 is connected to the spray pipe 2 .

[0038] Specifically, a plurality of air inlets 11 are provided on one side of the cowshed 1 , and the plurality of air inlets 11 are arranged on the cowshed 1 along the width direction of the cowshed 1 ; and a plurality of induced draft fans are provided on a side of the cowshed 1 away from the air inlets 11 .

[0039] The induced draft fan and the air inlet 11 correspond to each other. When the induced draft fan is working, air flows from the air inlet 11 to the induced draft fan, forming a ventilation tunnel between the induced draft fan and the air inlet 11, which can provide fresh outside air for the cowshed 1.

[0040] The chiller 4 of the present application can be connected to an external tap water source. The chiller 4 reduces the temperature of the tap water by exchanging heat with the tap water, so that the cooled low-temperature water enters the spray pipe 2 and is sprayed out from the atomizing nozzle 21, providing low-temperature cold water for the cowshed 1 to control the temperature of the cowshed 1.

[0041] In a more preferred embodiment, the chiller 4 of the present application provides cold water of 2°C-6°C for the spray pipe 2, and the cold water flowing out of the water outlet of the chiller 4 is pressurized by the pressure pump 3 and sent to the spray pipe 2, so that the cold water is sprayed from the atomizing nozzle 21. The atomizing nozzle 21 of the present application adopts a high-pressure atomizing nozzle 21.

[0042] The above-mentioned cooling system for the air inlet of the cowshed, the cowshed 1 is provided with an air inlet 11, the cooling system includes a spray device and a cold water supply device, the spray device includes a plurality of spray pipes 2, each spray pipe 2 can be movably arranged on the top of the cowshed 1, each spray pipe 2 is provided with a plurality of atomizing nozzles 21, and each atomizing nozzle 21 is arranged toward the air inlet 11 of the cowshed 1.

The cooling system can spray atomized cold water at the air inlet 11 of the cowshed 1 through the atomizing nozzle 21, so that the cold water supply device produces cold water in the form of mist and sprays it at the air inlet 11 of the cowshed 1. The atomized cold water flows through different positions of the cowshed 1 with the wind, and can cool down the cowshed 1, effectively control the temperature of the cowshed 1, reduce the impact of high temperature on the cattle, reduce the stress response of the cattle, and ensure the growth efficiency and milk production of the cattle. In addition, the spray pipe 2 of the present application can also be moved. During use, the spray pipe is moved to the corresponding position according to the position of the cattle, which is highly targeted and can achieve rapid cooling of the cowshed 1.

[0043] In a more preferred embodiment, a plurality of guide rails 12 are arranged on the top of the cowshed 1, each of the guide rails 12 is arranged along the width direction of the cowshed 1, and the guide rails 12 are parallel to each other. At least one spray pipe 2 is arranged on each of the guide rails 12, and the spray pipe 2 is slidably matched with the guide rail 12.

[0044] The guide rail 12 is arranged along the width direction of the cowshed 1. The guide rail 12 is arranged on one side of the air inlet 11, so that the movement of the spray tube 2 is arranged along the direction of the air inlet 11, so that the spray tube 2 can be arranged at the air inlet 11 on different sides.

[0045] The present application also provides a matching method between the guide rail 12 and the spray tube 2. Specifically, a card slot 121 is provided at the bottom of the guide rail 12, and the card slot 121 is provided along the length direction of the guide rail 12; a card strip 23 is provided at the top of the spray tube 2, and the card strip 23 and the card slot 121 are adapted to each other;

[0046] The spray pipe 2 is arranged on the guide rail 12 through the cooperation between the clamping strip 23 and the clamping slot 121;

[0047] The cowshed 1 is provided with a plurality of driving cylinders 6 , each of which corresponds to one of the guide rails 12 . A connecting plate 22 is provided at one end of the spray pipe 2 , and a piston rod of the driving cylinder is fixedly connected to the connecting plate 22 .

[0048] When the driving cylinder 6 starts working, the expansion and contraction of the piston rod drives the spray tube 2 to move on the guide rail 12, so that the spray tube 2 can move to the air inlet 11 at different positions.

[0049] In one embodiment, the air inlet 11 is arranged on the right side of the cowshed 1, and the induced draft fan is arranged on the left side of the cowshed 1. A plurality of air inlets 11 are arranged on the right side of the cowshed 1 and are evenly distributed along the front-to-back direction of the cowshed 1. During application, if most of the cattle are at the front side of the cowshed 1, the spray pipe 2 is moved to the front side of the cowshed 1 so that the atomizing nozzle 21 sprays atomized cold water at the air inlet 11 at the front side of the cowshed 1; if most of the cattle are at the back side of the cowshed 1, the spray pipe 2 is moved to the back side of the cowshed 1 so that the atomizing nozzle 21 sprays atomized cold water at the air inlet 11 at the back side of the cowshed 1. The movable spray pipe 2 can spray atomized cold water at different positions in a targeted manner during use, so that different positions of the cowshed 1 can be quickly cooled down in a targeted manner, and the cooling effect on the cattle is better.

[0050] Specifically, a plurality of the atomizing nozzles 21 are arranged at intervals on the spray pipe 2, and the distance between two adjacent atomizing nozzles 21 is 1 meter to 1.5 meters. The atomizing nozzles 21 arranged at intervals can ensure that each position of the spray pipe 2 sprays atomized cold water uniformly, thereby ensuring the cooling effect on the cowshed 1.

[0051] Furthermore, the cowshed 1 also includes a controller. A plurality of temperature detectors 13 are also provided in the cowshed 1. The temperature detectors 13, the cold water supply device and the induced draft fan are all electrically connected to the controller.

[0052] The temperature detector 13 is used to detect the temperature of the cowshed 1, and the controller controls the operation of the chiller 4 according to the temperature data fed back by the temperature detector 13. If the temperature fed back by the temperature detector 13 is too high, the chiller 4 operates at a higher power to provide cold water at a lower temperature.

[0053] More specifically, a water distribution pipe 7 is further provided on the top of the cowshed 1 , and the water distribution pipe 7 is connected to the water outlet of the pressure pump 3 , and the water distribution pipe 7 is connected to the spray pipe 2 through a hose 71 .

[0054] The water distribution pipe 7 can be detachably fixed on the top of the cowshed 1 . The water distribution pipe 7 serves to evenly supply cold water to different spray pipes 2 , while the setting of the hose 71 will not affect the movement of the spray pipe 2 .

[0055] In a more preferred embodiment, a filter 5 is provided at the water inlet of the chiller 4, and the filter 5 includes a shell 51, in which a filter channel 52 is formed, one end of the filter channel 52 is connected to the water inlet of the chiller 4, and the other end is connected to an external water source; the present application filters the external water source through the filter 5 to improve the cleanliness of the water source used for cooling, thereby preventing the cooling water from polluting the cowshed and affecting the health of the cattle.

[0056] Along the flow direction of the water flow, the filter channel 52 is provided with a plurality of filter layers. Specifically, the plurality of filter layers include a pre-filter layer 54, a PP cotton filter layer 55 and an activated carbon filter layer 56 which are sequentially arranged along the flow direction of the water flow. The pre-filter layer 54 uses a filter screen with a larger aperture (such as 30 to 50 microns) to remove large particles of impurities in the water to extend the service life of the subsequent filter element. The PP cotton filter layer 55 can effectively remove impurities larger than 1 micron in the water. The activated carbon filter layer 56 is used to remove odors, organic matter and microorganisms in the water, and is usually placed after the PP cotton to further purify the water quality.

[0057] Furthermore, a mounting port is provided at the top of the shell 51, and the mounting port is connected to the filter channel 52; a plurality of snap-in positions are provided in the filter channel 52, and the snap-in positions include two relatively arranged clamping blocks 53, and the clamping blocks 53 are fixed in the shell 51, and a filter layer is provided in each of the snap-in positions.

[0058] The clamping block 53 is provided with a groove, and a clamping position capable of clamping the filter layer is formed between the grooves of the two clamping blocks 53.
