Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cowshed cooling and ventilation, in particular to a cowshed intelligent ventilation and cooling combined device. BACKGROUND

[0002] Livestock industry, especially dairy and beef cattle breeding, its production efficiency and animal health are closely related, and the environment in the shed is a key factor affecting animal health. In the hot and humid summer, a large amount of heat and moisture is easily accumulated in the cowshed, and at the same time, high-concentration harmful gases such as ammonia and hydrogen sulfide are produced in the process of livestock breathing, manure fermentation, etc. This harsh environment is extremely easy to cause heat stress in livestock, which shows a series of problems such as reduced appetite, decreased immunity, slow growth, and reduced milk production, etc., which brings huge economic losses to the breeding industry.

[0003] At present, the traditional cowshed environment control mainly relies on the following technical means: Fixed ventilation system: usually install several axial flow fans on the side wall or roof of the cowshed for forced ventilation. However, such fans are fixed in position, with limited ventilation range, and are easy to form air flow dead angles in the shed, making it difficult to effectively and uniformly exhaust the dirty air and harmful gases at the bottom. In addition, the single-direction ventilation mode is difficult to adapt to the environmental regulation needs under different seasons and weather conditions.

[0004] Local cooling measures: common cooling methods include installing ceiling fans, spray heads or wet curtain-fan systems in the shed. Ceiling fans can only promote air flow and cannot effectively reduce temperature; fixed-position spray systems are easy to cause over-wetting in the spraying area, while other areas are still hot and dry, the cooling is uneven, and it is easy to cause water resource waste and ground environmental pollution; although the wet curtain-fan system has obvious cooling effect, its initial investment and operation cost is high, and it has high requirements for water quality, the wet curtain is easy to block and damage, and the maintenance workload is large.

[0005] Manual control mode: the start-stop and adjustment of the existing system mostly rely on manual experience judgment, lacking closed-loop linkage control with real-time environmental parameters. This extensive management mode has a lagging response, and it is difficult to achieve precise environmental regulation, and increases the labor cost. SUMMARY

[0016] Preferably, the transmission ratio between the gear one, the gear two, the gear three, the worm and the worm wheel is set as 5:10:10:10:1.

[0017] Preferably, the left and right sidewalls inside the cowshed body are provided with guide rails distributed along the length direction thereof, and the guide rails on the two sides are both internally provided with a guide assembly connected with the ventilation and cooling mechanism.

[0018] Compared with the prior art, the present application provides a cowshed intelligent ventilation and cooling combined device, which has the following beneficial effects: Efficient and accurate environmental control, significantly improving livestock welfare Active directional ventilation: through the symmetrical arrangement of the arc-shaped air suction hood and the exhaust fan, the humid, hot and dirty air gathered at the bottom of the cowshed (livestock activity area) can be forcedly discharged accurately and efficiently. This "from bottom to top" ventilation mode is more in line with the distribution law of harmful gases and heat, and the ventilation efficiency is much higher than that of traditional natural ventilation or top fan, which can quickly reduce the concentration of harmful gases such as ammonia and hydrogen sulfide, and protect the respiratory health of livestock.

[0019] Evaporative cooling and uniform humidification: the transversely arranged atomizing spray system is moved in cooperation with the mechanism to take away a large amount of heat while evaporating water, achieving rapid and uniform cooling effect. The 45-degree deflection design of the spray head further expands the water mist coverage range, avoiding local over-wetting or dryness, and creating a cool and comfortable microclimate environment for livestock, effectively relieving heat stress and improving feed intake and production performance.

[0020] Intelligent and automatic operation, improving management efficiency: the device is linked with the environmental sensor and the control unit, which can monitor the temperature, humidity and air quality parameters in the cowshed in real time, and automatically start, stop and adjust the operation state accordingly. It realizes the leap from "experience management" to "data-driven management", greatly reducing manual intervention and labor intensity.

[0021] Scanning type without dead angle operation: the ventilation and cooling mechanism can reciprocate along the length direction of the cowshed under the action of the driving part, like a "moving environmental purification station", ensuring that the entire cowshed space, especially the corners that are difficult to cover by traditional fixed equipment, can be uniformly ventilated and cooled, eliminating the environmental control blind area.

[0022] The structure is designed ingeniously, and the operation is stable and reliable Integrated design: The ventilation, cooling, driving, guiding and other functional modules are highly integrated on a movable gantry structure, which is compact in structure and does not occupy additional ground space, facilitating the modification and installation in the existing cowshed.

[0023] Smooth driving and precise guidance: The screw nut transmission is adopted, and the multi-stage gear-worm gear reducer system is matched, which not only provides sufficient driving force, but also realizes low-speed, smooth and precise movement control, avoids shaking and impact. The introduction of the guiding assembly (guide column and sleeve) effectively resists the lateral force that may be generated during the movement of the mechanism, ensures the stability and straightness during long-distance operation, prevents jamming and deviation, and prolongs the service life of the equipment.

[0024] Optimization of energy and resource utilization, economic and environmental protection Synergistic energy saving: The ventilation and cooling processes are carried out simultaneously, and the negative pressure environment created by the exhaust fan helps to accelerate the evaporation and diffusion of water mist, improving the cooling efficiency; at the same time, the evaporative cooling also reduces the sensible heat load of the air, so that the energy consumption of ventilation is relatively reduced. The two work together to achieve the energy saving effect of "1+1>2".

[0025] Efficient use of water resources: The atomizing spray head is used to break the water into fine beads, greatly increasing the contact area between water and air and improving the evaporation efficiency, and the water consumption is far less than that of traditional spraying or water curtain systems, saving water resources. The intelligent ventilation and cooling combined device for cowshed successfully builds an efficient, stable and energy-saving cowshed environment control solution through the movable integrated design, the synergistic effect of ventilation and evaporative cooling and the intelligent control based on environmental perception. It not only can significantly improve the air quality and thermal environment in the shed, directly improve the health status and production efficiency of livestock, but also through automation and precision operation, reduces the labor cost and management difficulty of the farm. The device has reasonable structure and reliable operation, realizes the double improvement of animal welfare and production efficiency, and also embodies the trend of modern livestock equipment towards intelligence, refinement and green environmental protection, which has high popularization and application value.

[0032] The cowshed intelligent ventilation and cooling combined device of the embodiment mainly comprises a cowshed body 1, a roof 2, a support column 3, a ventilation and cooling mechanism 5 and a front and rear driving member 6.

[0033] The cowshed body 1 is the main structure of the device. The roof 2 is fixedly installed above the cowshed body 1 through a plurality of support columns 3. A gap is left between the roof 2 and the two side walls of the cowshed body 1, so that a continuous ventilation window 4 is formed on each side of the cowshed in the length direction. The ventilation and cooling mechanism 5 is in the form of a gantry structure and is arranged in the internal space of the cowshed body 1. The front and rear driving member 6 is fixedly installed at the bottom of the roof 2 and is in transmission connection with the top of the ventilation and cooling mechanism 5, and is used to drive the mechanism to move along the length direction of the cowshed (i.e. the front and rear direction). Specifically, the ventilation and cooling mechanism 5 comprises an arc-shaped air suction cover 51, an exhaust fan 52, a spraying horizontal pipe 53, a spraying head 54 and a liquid supply assembly 55. The arc-shaped air suction cover 51 is provided with two arc-shaped air suction covers 51 which are symmetrically fixed to the two side walls near the inside of the cowshed body 1. The exhaust fan 52 is installed on the outer cover wall of each arc-shaped air suction cover 51, and the exhaust fan 52 is opposite to and located at the ventilation window 4 on the same side. The spraying horizontal pipe 53 is horizontally arranged between the top ends of the two arc-shaped air suction covers 51.

The liquid supply assembly 55 is provided with two sets of liquid supply assemblies 55 which are correspondingly installed on the left and right sides of the top of the spraying horizontal pipe 53 and are in fluid communication with the inside of the spraying horizontal pipe 53, and is used to supply liquid to the spraying horizontal pipe 53.

[0034] Further, in order to uniformly suck the air in the cowshed, a plurality of air inlet holes 511 are uniformly arranged on the inner cover wall of each arc-shaped air suction cover 51.

[0035] The specific structure of the liquid supply assembly 55 comprises a liquid storage tank 551, a liquid pumping pump 552 and a liquid guide pipe 553.

[0036] In order to optimize the spraying effect, the installation angle of each spraying head 54 is deflected by 45 degrees relative to the vertical center line. Preferably, all the spraying heads 54 are mist spraying heads which can generate fine mist. Embodiment two:

[0037] On the basis of embodiment one, the front and rear driving member 6 is described in detail in this embodiment.

[0038] The front and rear driving members 6 comprise a mounting seat 61, a screw rod 62, a screw rod sleeve 63 and a rotary driving member 64. The mounting seat 61 is provided with two, respectively fixedly installed at the front and rear end positions of the inner surface of the bottom of the roof 2. The screw rod 62 is rotatably supported between the front and rear two mounting seats 61 through a bearing. The screw rod sleeve 63 is threadedly sleeved on the screw rod 62, and the outer side thereof is fixedly connected with the top center position of the ventilation and cooling mechanism 5. The rotary driving member 64 is installed on the mounting seat 61 at the front end and is in transmission connection with the front end of the screw rod 62, for driving the screw rod 62 to rotate forward and backward.

[0039] A preferred structure of the rotary driving member 64 comprises a motor 641, a gear one 642, two gears two 643, two gears three 644, two worm rods 645, a worm wheel 646, a shaft coupling 647 and a worm rod mounting plate 648. The motor 641 is fixedly installed on the mounting seat 61 at the front end. The gear one 642 is directly sleeved on the output shaft of the motor 641. The gear two 643 is provided with two, respectively symmetrically engaged on the left and right sides of the gear one 642. The gear three 644 is also provided with two, respectively engaged with the left and right two gears two 643. The worm rod 645 is provided with two, rotatably installed between the front and rear end provided worm rod mounting plates 648 through bearings.

The shaft coupling 647 is used for connecting the center shaft of the worm wheel 646 with the front end shaft of the screw rod 62.

[0040] In order to obtain appropriate transmission speed and torque, the transmission ratio between the gear one 642, the gear two 643, the gear three 644, the worm rod 645 and the worm wheel 646 is preferably set to 5:10:10:10:1. Embodiment three:

[0041] On the basis of the embodiment one or two, this embodiment further increases a guide structure to ensure the stability of the movement of the ventilation and cooling mechanism 5.

[0042] On the left and right side walls inside the cowshed body 1, each is fixedly installed with a guide rail 11 extending along the length direction of the cowshed. Inside each guide rail 11, a set of guide assembly 7 is arranged. The guide assembly 7 is connected with the same side of the bottom of the ventilation and cooling mechanism 5.

[0043] Specifically, the guide assembly 7 comprises a guide column 71 and a guide sleeve 72. The guide column 71 is fixedly installed inside the guide rail 11. The guide sleeve 72 is slidably sleeved on the guide column 71. The inner side wall of the guide sleeve 72 is fixedly connected with the corresponding side of the ventilation and cooling mechanism 5 (specifically the bottom of the arc-shaped air suction hood 51).

[0044] Specific working steps: Start-up and command receiving: The system starts up, and the control unit (not shown in the figure, but necessary for the intelligent system) receives signals from the environmental sensors inside the cowshed (such as temperature, humidity, and harmful gas concentration sensors) or preset program instructions. Drive mechanism start-up and positioning: When it is necessary to start the ventilation and cooling function, the control unit issues an action command to the front and rear drive members 6.

[0045] The motor 641 in the rotary drive member 64 starts up.

[0046] The motor 641 transmits power and motion to the lead screw 62 through a multi-stage transmission system composed of gear one 642, gear two 643, gear three 644, worm 645, worm gear 646, etc., to drive the lead screw to rotate.

[0047] The rotary motion of the lead screw is converted into linear motion by the lead screw sleeve 63, thereby driving the entire ventilation and cooling mechanism 5 to move along the length direction of the cowshed to the target working area or to start scanning movement.

[0048] Ventilation process (synchronized with movement): At the same time that the ventilation and cooling mechanism 5 moves, the exhaust fan 52 starts up.

[0049] The exhaust fan 52 operates, and through the air inlet holes 511 on the inner cover wall of the arc-shaped air suction cover 51, it sucks the humid and hot air, dirty air (with a higher density) accumulated at the bottom of the cowshed into the cover.

[0050] The sucked air is forced by the exhaust fan 52 to be discharged to the outside of the cowshed through the ventilation window 4.

[0051] This process forms a negative pressure in the cowshed, prompting fresh air from the outside to enter from the other end or the lower air inlet of the cowshed, achieving air exchange and ventilation.

[0052] Cooling and humidification process (synchronized with movement): At the same time, the liquid supply assembly 55 starts working. The liquid pump 552 extracts cooling liquid (usually water) from the liquid storage tank 551.

[0053] The liquid is pumped into the spray horizontal pipe 53 through the liquid guide pipe 553.

[0054] The liquid is sprayed out from the spray heads 54 evenly distributed at the bottom of the spray horizontal pipe under the action of pressure.

[0055] Since the spray heads 54 are set as mist spray heads and are deflected at an angle of 45 degrees, the sprayed liquid forms a water mist with a wide coverage and fine and uniform distribution.

[0056] The water mist mixes with the air in the cowshed, absorbs a large amount of heat through evaporation of water, effectively reduces the environmental temperature in the cowshed, and increases the air humidity.

[0057] Movement and guidance: During the whole working process, the front and rear driving members 6 continuously work, so that the ventilation and cooling mechanism 5 slowly and stably moves along the length direction of the cowshed.

[0058] The guiding assembly 7 works synchronously: the guiding sleeve 72 fixed to the bottom of the ventilation and cooling mechanism slides along the guiding column 71 fixed to the side wall guiding rail 11 of the cowshed, so that the mechanism does not deviate or be stuck during the movement, and stably runs.

[0059] Cyclic work and stop: The ventilation and cooling mechanism 5 reciprocally moves in the cowshed (for example, moves from one end to the other end and returns) under the action of the driving members, so that the ventilation and cooling are performed without dead angle in the whole cowshed space.

[0060] When the environmental sensor detects that the environmental parameters in the cowshed reach the set target value (for example, the temperature is reduced to the appropriate range) or the preset working time is reached, the control unit issues a stop instruction.

[0061] The exhaust fan 52, the liquid pump 552 and the driving motor 641 are sequentially stopped, and the ventilation and cooling mechanism 5 can be stopped at the initial position or the standby position.

[0062] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0063] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
