Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of livestock and poultry houses, and particularly relates to a ventilation system for livestock and poultry houses. Background Art
[0002] In the existing ventilation systems for livestock and poultry houses, the tunnel ventilation mode and the precision ventilation mode are usually adopted. There are practical problems in the traditional tunnel ventilation mode, such as a large proportion of ineffective ventilation and a relatively low wind speed in the activity area of the pig group. However, the advantage of its large ventilation volume makes the temperature in the pig house significantly lower than that in the precision ventilation pig house. Especially, the wind speed in the personnel activity area is obvious, which is relatively friendly to the staff. Although precision ventilation can effectively increase the wind speed in the activity area of the pig group and relieve the heat stress of the pigs, the overall ventilation volume decreases, resulting in a relatively high temperature in the house. Especially, there is no wind speed in the personnel activity area, and it is a gathering place for dirty air, which makes the pig houses in the precision ventilation mode resisted by the breeding personnel.
[0003] In addition, to ensure the uniformity of the incoming air in winter for tunnel ventilation, ceiling air inlets are usually added, which damages the integrity of the ceiling. In summer ventilation, the hot air in the ceiling chamber can enter the pig house through the gaps of the ceiling air inlets, affecting the temperature conditions in the pig house. For precision ventilation, to ensure the uniformity of the exhaust air, many normally open exhaust holes are opened in the ceiling, which is not conducive to heat preservation in summer and heat insulation in winter.
[0004] Therefore, there are respective drawbacks in using only the tunnel ventilation mode or the precision ventilation mode alone, and the ventilation efficiency of the ventilation systems for livestock and poultry houses in the prior art is relatively poor.
[0005] Therefore, the prior art needs to be further developed. Content of the Utility Model
[0006] The purpose of the utility model is to overcome the above technical deficiencies and provide a ventilation system for livestock and poultry houses to solve the technical problem of relatively poor ventilation efficiency of the ventilation systems for livestock and poultry houses in the related technologies.

One end of the traction rope is connected to the piston rod of the driving cylinder, and the other end of the traction rope is fixedly arranged on the side wall of the livestock house body.

Detailed implementation manners
[0028] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0029] According to an embodiment of the present invention, a ventilation system for a livestock and poultry house is provided. Please refer to Figures 1 to 6 , including: a livestock and poultry house body 1, the interior of the livestock and poultry house body 1 includes a pen 2 for livestock and poultry; an air inlet 3, the air inlet 3 is communicated with the interior of the livestock and poultry house body 1 to form a ventilation space 4 inside the livestock and poultry house body 1; an air supply duct 5, the air supply duct 5 is communicated with the air inlet 3, the air supply duct 5 is provided with an air supply opening 51, the opening of the air supply opening 51 faces the pen 2, and a wind blocking member is provided at the air supply opening 51, and the wind blocking member is movably arranged relative to the air supply opening 51 to adjust the flow direction of the air flow output from the air supply opening 51.
[0030] Specifically, tunnel ventilation can be realized in the livestock and poultry house through the ventilation space 4. By setting the air supply duct 5 and the air supply opening 51, accurate air supply to the pen 2 is realized, reducing ineffective ventilation and reducing the heat stress of livestock and poultry such as pigs. The movable design of the wind blocking member can adjust the flow direction of the air flow output from the air supply opening 51, so that the flow direction of the air flow can be adjusted according to different ventilation requirements; on the basis of tunnel ventilation, adding the air supply duct 5 and the air supply opening 51 to realize accurate air supply, the two sets of air supply systems can be regulated according to different seasonal requirements. The two sets of ventilation systems can be combined with each other or can be separately turned on, thus making up for the deficiencies of a single ventilation mode, improving the ventilation efficiency in the livestock and poultry house, realizing the common use in winter and summer, providing a more comfortable and healthy growth environment for livestock and poultry, and solving the technical problem of poor ventilation efficiency of the ventilation system in the livestock and poultry house in the related art.
[0031] It can be understood that the heat-sensitive area of livestock and poultry such as pigs is located at the head and neck. Therefore, when the livestock and poultry house ventilation system in this embodiment is applied to livestock and poultry houses such as pig houses, the air supply duct 5 can be installed directly above the pen, and the air supply port 51 can accurately blow the air flow towards the head and neck of the pigs, thereby achieving effective ventilation and effectively alleviating the heat stress of the pigs.
[0032] In some embodiments, considering the influence of the horizontal wind speed, to ensure that the air flow from the air supply port 51 can accurately blow to the head and neck positions of livestock and poultry such as pigs, for example, the opening of the air supply port 51 can be offset 240 mm from the head and neck position of the livestock and poultry.
[0033] In the livestock and poultry house ventilation system of this embodiment, referring to Figure 2 , the wind blocking component includes: a wind blocking plate 6, the wind blocking plate 6 is arranged opposite to the air supply port 51; a traction device, the traction device is connected to the wind blocking plate 6, and the traction device is used to traction the wind blocking plate 6 to move, so as to block or expose the air supply port 51. When the air supply port 51 is exposed, the air flow output from the air supply port 51 blows towards the pen 2. Through the above settings, the wind blocking plate 6 can be tractioned to move back and forth, thereby adjusting the direction of the output air flow. When the air supply port 51 is exposed by moving the wind blocking plate 6, the air flow output from the air supply port 51 blows towards the pen 2, and the air flow is accurately blown towards livestock and poultry such as pigs. When the air supply port 51 is blocked by moving the wind blocking plate 6, the air flow output from the air supply port 51 will no longer directly blow towards the pen 2, and the air flow will reach the pen 2 in a dispersed state, avoiding the cold air blowing directly on livestock and poultry such as pigs.
[0034] It can be understood that the size of the wind blocking plate 6 must be able to cover the air supply port 51. For example, the wind blocking plate 6 can be set to 200 mm * 200 mm.
[0035] In the livestock and poultry house ventilation system of this embodiment, referring to Figure 1 , the traction device includes: a driving cylinder 71 and a traction rope 72. The wind blocking plate 6 is strung on the traction rope 72.

Through the above settings, the wind blocking plate 6 can be automatically controlled to move back and forth by the driving cylinder 71, realizing automatic control.
[0036] In some embodiments, at the end far from the driving cylinder 71, the traction rope 72 is fixed on the side wall of the livestock and poultry house body 1 through a return spring 74, thereby realizing the rapid reset of the wind blocking plate 6.
[0037] Specifically, the extending direction of the traction rope 72 is parallel to the extending direction of the air supply duct 5.

Through the above settings, the air intake flow rates of the tunnel ventilation mode and the precision ventilation mode can be controlled separately, or the opening and closing of the tunnel ventilation mode and the precision ventilation mode can be controlled separately.
[0042] In some embodiments, an adjustable louver is installed at the first air inlet 31, and the opening degree of the louver can be adjusted according to requirements. In addition, a window opener can be added and connected to the controller to automatically control the louver.
[0043] In the ventilation system of the livestock and poultry house in this embodiment, refer to Figure 1 , a fan 321 is provided at the second air inlet 32, and the outlet of the fan 321 faces the air supply duct 5. By controlling the opening degree of the fan 321, the air intake flow rate of the precision air supply mode can be controlled, and by controlling the opening and closing of the fan 321, the opening and closing of the precision air supply mode can be controlled.
[0044] In some embodiments, to ensure the uniformity of the incoming air in the house, the fan 321 is placed above the air inlet louver to ensure that the air inlet louvers are evenly distributed; in addition, the fan 321 is frequency-controlled to facilitate adjusting the air outlet speed and air volume.
[0045] In the ventilation system of the livestock and poultry house in this embodiment, refer to Figure 6 , the interior of the livestock and poultry house body 1 includes a plurality of pens 2, and the plurality of pens are arranged in parallel; a plurality of air supply openings 51 are correspondingly formed on the air supply duct, and the plurality of air supply openings 51 are arranged in one-to-one correspondence with the plurality of pens; the baffle plates 6 include a plurality, and the plurality of baffle plates 6 are arranged in one-to-one correspondence with the plurality of air supply openings 51. Through the above settings, precise air supply can be achieved in each pen 2.
[0046] In some embodiments, the interior of the livestock and poultry house body 1 includes multiple rows of pens 2, and correspondingly, multiple air supply ducts 5 are provided to ensure that precise air supply can be achieved for each row of pens.

By providing the traction track 73, it can be used to support the plurality of windshields 6 and at the same time guide the moving direction of the plurality of windshields 6, preventing the windshields 6 from tilting when they do not receive sufficient support, which affects the shielding effect on the air supply opening 51.
[0048] In the ventilation system of the livestock and poultry house in this embodiment, refer to Figure 1 The ventilation system of the livestock and poultry house includes an exhaust fan 81, and the exhaust fan 81 is located at the air outlet of the livestock and poultry house body 1. By providing the exhaust fan 81, the exhaust rate of the livestock and poultry house body 1 can be controlled, further improving the ventilation efficiency of the livestock and poultry house body 1.
[0049] In the ventilation system of the livestock and poultry house in this embodiment, refer to Figure 1 The ventilation system of the livestock and poultry house includes a wet curtain 82. The wet curtain 82 is arranged before the air inlet 3 so that the air flow entering the livestock and poultry house body 1 first passes through the wet curtain 82 to increase the humidity of the air flow. Specifically, by providing the wet curtain 82, the temperature of the air flow entering the livestock and poultry house body 1 can be reduced, ensuring that the fresh air sent to the pig position in summer is cold air.

[0052] The ventilation system of the livestock and poultry house in this embodiment cancels the ceiling air inlet window, ensuring the integrity of the ceiling, and can be used in both winter and summer: in summer conditions, the driving cylinder 71 is used to uniformly open the windshields 6 to ensure vertical air outlet; in winter conditions, the driving cylinder 71 is used to adjust the windshields 6 to directly below the air supply opening 51, ensuring that the adjustment angle of the windshields 6 makes the air outlet horizontal, and fully mixing and preheating with the hot air in the house before reaching the pig activity area, avoiding direct cold air blowing on the pigs.
[0053] When applying the ventilation system of the livestock and poultry house in this embodiment to livestock and poultry houses such as pig houses, the control method of the ventilation system of the livestock and poultry house is as follows:
[0054] ① Refer to Figures 4 - 5, when the temperature in the pigsty is lower than 20 °C (the lower limit of the comfortable temperature in the pigsty), the intake air louvers are closed, the fan 321 is turned on, the driving cylinder 71 adjusts the wind deflector 6 to face the air supply outlet 51, and as the temperature drops, the rotational speed of the fan 321 decreases, and the rotational speed of the exhaust fan 81 decreases synchronously;
[0055] ② When the temperature in the pigsty is higher than 20 °C, the fan 321 is turned off, and at the same time the intake air louvers are opened. As the temperature rises, the opening degree of the louvers increases and the rotational speed of the exhaust fan 81 increases;
[0056] ③ When the temperature in the pigsty reaches 27 °C, the wet curtain 82 is turned on;
[0057] ④ Refer to Figures 1 - 3 , when the temperature in the pigsty is still higher than 27 °C after the wet curtain is turned on, keep the wet curtain 82 and the louvers open, turn on the fan 321, and the driving cylinder 71 adjusts the wind deflector 6 to deviate from the air supply outlet 51. After that, as the temperature in the pigsty rises, the rotational speed of the fan 321 increases.
[0058] When applying the ventilation system for livestock and poultry houses in this embodiment to pigsties and other livestock and poultry houses, the advantages of better temperature conditions in the tunnel ventilation house and obvious wind speed in the personnel activity area are combined with the advantage that precise air supply to pig positions can effectively relieve the heat stress of pigs.
