Abstract
Description
Technical Field
[0001] This application relates to ventilation and cooling technology for cattle sheds, and more particularly to a ventilation and cooling device for cattle sheds. Background Technology
[0002] In summer, cattle sheds need to be well ventilated and cooled to prevent the air temperature inside the shed from exceeding 28°C, which can cause heat stress in cattle. Overheating can lead to decreased appetite, weakened physical condition, or even heatstroke and coma in cattle.
[0003] In northern livestock farming, the ventilation and cooling devices used in cattle sheds are usually axial flow fans. When the temperature is too high, a sprinkler system is used to spray water on the ground to cool it down. However, the water sprayed by the sprinkler system falls to the ground quickly and cannot cool the air temperature inside the cattle shed rapidly, resulting in poor cooling effect during the midday high-temperature period. Utility Model Content
[0004] This application provides a cattle shed ventilation and cooling device to solve the problems of slow adjustment speed and poor cooling effect of existing cattle shed ventilation and cooling devices.
[0005] This application provides a ventilation and cooling device for cattle sheds, including a top frame and a column. A fan blowing air vertically upwards is fixed on the column. Below the fan is a box embedded in the ground and a pre-embedded main pipe. The top of the box is covered with a perforated plate. A branch pipe is horizontally fixed inside the box. The branch pipe has a through hole for discharging water mist. The main pipe connected to a water source is sequentially connected to an ultrasonic atomizer inside the box. The mist outlet of the ultrasonic atomizer is connected to the branch pipe.
[0006] Optionally, a guide plate is fixed to the bottom surface of the orifice plate above the branch pipe, and the guide plate is arranged along the length direction of the branch pipe.
[0007] Optionally, the bottom of the box is a slope, and a drain pipe connected to a sewage pipe is provided at the lowest point of the slope.
[0008] Optionally, the ground around the perimeter of the enclosure is provided with upward-protruding retaining rings.
[0009] Optionally, one end of the fan is rotatably connected to the column, and the other end of the fan is rotatably connected to a fixed plate suspended on the top frame. A servo motor for rotating the fan is installed on the fixed plate.
[0010] The cattle shed ventilation and cooling device provided in this application first uses a fan to blow air upwards along the columns, forming an upward airflow. Then, an ultrasonic atomizer atomizes water into tiny droplets, which are then discharged from a perforated plate. The water mist discharged from the perforated plate absorbs heat and converts into water vapor as it rises with the airflow, and is then discharged from the top of the cattle shed by the fan. While ventilating and cooling the cattle shed through the fan, the addition of water mist to the airflow generated by the fan, through the housing and ultrasonic atomizer, not only increases air humidity but also absorbs and carries away heat from the air inside the cattle shed, further enhancing the cooling effect.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0020] like Figures 1-5 As shown, one embodiment of this application provides a ventilation and cooling device for cattle sheds, including a top frame 1 and a column 2. A fan 3 that blows air vertically upwards is fixed on the column 2. Below the fan 3, there is a box 4 embedded in the ground and a pre-embedded main pipe 7. The top of the box 4 is covered with a perforated plate 5. A branch pipe 6 is horizontally fixed inside the box 4. The branch pipe 6 is provided with a through hole for discharging water mist. The main pipe 7, which is connected to a water source, is sequentially connected to an ultrasonic atomizer 8 inside the box 4. The mist outlet of the ultrasonic atomizer 8 is connected to the branch pipe 6.
[0021] When in use, fan 3 is turned on. The upward-blowing fan 3 creates a negative pressure for synchronous air intake below, forming an upward airflow along the column 2. Simultaneously, water is introduced into the ultrasonic atomizer 8 through the main pipe 7. The ultrasonic atomizer 8 atomizes the water into tiny droplets, which are then discharged from the through-holes on the branch pipe 6. The water mist discharged from the branch pipe 6 overflows from the perforated plate 5 and rises with the airflow. As the tiny water droplets rise, they absorb heat from the air and convert into water vapor, which is then blown out of the cattle shed by fan 3.
[0022] In this embodiment, the fan 3 first blows air upwards along the column 2 to form an upward airflow. Then, the ultrasonic atomizer 8 atomizes water into tiny droplets, which are then discharged from the perforated plate 5. The water mist discharged from the perforated plate 5 absorbs heat and converts into water vapor as it rises with the airflow, and is then discharged from the top of the cattle shed by the fan 3. While the fan 3 ventilates and cools the cattle shed, the water mist added to the airflow generated by the fan 3 through the housing 4 and the ultrasonic atomizer 8 not only increases air humidity but also absorbs and removes heat from the air inside the cattle shed, further enhancing the cooling effect.
[0023] In one possible implementation, a guide plate 9 is fixed to the bottom surface of the orifice plate 5 above the branch pipe 6, and the guide plate 9 is arranged along the length direction of the branch pipe 6.
[0024] The baffle 9 is used to block and protect the through holes on the branch pipe 6 along its length, preventing the through holes on the branch pipe 6 from being blocked by debris entering the housing 4. The water mist discharged from the branch pipe 6 can bypass the two sides of the baffle 9 and rise to overflow from the orifice plate 5.
[0025] In one possible implementation, the bottom of the box 4 is a slope, and a drain pipe 10 connected to a sewage pipe is provided at the lowest point of the slope.
[0026] The sewage entering the box 4 flows into the sewage pipe 10 through the inclined surface, and finally enters the sewage pipe through the sewage pipe 10 and is discharged from the cattle shed.
[0027] In one possible implementation, a retaining ring 11 protruding upwards is provided on the ground around the edge of the housing 4.
[0028] The upward-protruding baffle ring 11 can effectively prevent most of the sewage from entering the tank 4.
[0029] In one possible implementation, one end of the fan 3 is rotatably connected to the column 2, and the other end of the fan 3 is rotatably connected to the fixed plate 12 suspended on the top frame 1. The fixed plate 12 is equipped with a servo motor 13 for rotating the fan 3.
[0030] The servo motor 13 can rotate the fan 3 along the shafts at both ends to adjust its blowing direction and tilt angle, or after the ultrasonic atomizer 8 is turned off, the fan 3 can be rotated to blow air downwards to directly cool the cattle in the barn.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
