Technical Field
[0001] This utility model relates to the field of aquaculture technology, and in particular to a ventilation and air exchange control device for sheep sheds. Background Technology
[0002] With the rapid development of the livestock industry, the improvement of modern breeding environment has become one of the key factors to improve animal production efficiency and ensure animal health. In the breeding process, especially in sheepfolds and other human livestock breeding sites, the regulation of the environment has an important impact on animal growth, health and breeding efficiency. As one of the core components of sheepfold environmental control, the ventilation system is directly related to key indicators such as air quality, temperature and humidity and carbon dioxide concentration in the shed.
[0003] The existing sheep sheds are not built with dedicated ventilation devices and rely on cross-ventilation through windows. This ventilation method cannot effectively remove the polluted air from the sheep shed in windless weather. In addition, the sheep beds inside the sheep sheds are generally installed on the ground, which cannot provide good ventilation, causing manure to accumulate and exacerbating the odor inside the sheep shed.
[0004] Existing patent (publication number: CN215873001U) discloses a sheepfold ventilation and deodorization device, comprising a sheepfold body, which includes walls and a roof. Inside the sheepfold body, a sheep bed is installed. A manure-guiding ramp is located at the center of the bottom of the sheepfold body below the sheep bed. Strip-shaped channels are respectively provided between the two sides of the manure-guiding ramp and the inner wall of the wall. Rapid manure removal mechanisms are rotatably installed inside each strip-shaped channel. Ventilation and deodorization components are evenly distributed on the wall below the sheep bed. This utility model has the advantage of good ventilation, which can quickly discharge manure from inside the sheepfold body and reduce odor generation.
[0005] Existing patents offer solutions to the above problems, but they have limitations such as not being able to deliver cool or warm air into the sheepfold when the temperature is high or low, and not being able to control the ventilation system in a closed loop.
[0006] Therefore, a ventilation and air exchange control device for sheep sheds is proposed. Utility Model Content
[0007] The purpose of this utility model is to provide a ventilation and air exchange control device for sheep sheds, which can solve the problems of existing sheep shed ventilation and deodorization devices that cannot deliver cool or warm air into the sheep shed when the temperature is high or low, and that cannot perform closed-loop control of ventilation and air supply.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a ventilation and air exchange control device for sheep sheds, comprising a sheep shed body, the sheep shed body comprising a frame and a roof, air intake mechanisms being provided on both sides of the frame, and an exhaust mechanism being provided on the top of the roof;
[0009] The air intake mechanism includes a U-shaped tube with its two ends located on both sides of the frame. The bottom of the U-shaped tube is located inside the soil below the frame. An air intake hood is provided at one point of the U-shaped tube, and a blower is provided inside the air intake hood. The air intake hood is located on the outside of the frame, and a closing component is provided at one end of the U-shaped tube.
[0010] Preferably, the closing assembly includes a top cover disposed at one end of the U-shaped tube, a first electric push rod is bolted to the top of the top cover, a T-shaped disk is fixedly connected to the output end of the first electric push rod, the T-shaped disk is movably disposed at one end of the U-shaped tube, and the T-shaped disk is movably disposed at one end of the air intake shroud.
[0011] Preferably, the exhaust mechanism includes a vertical pipe disposed in the middle of the roof, inclined pipes fixedly disposed on both sides of the vertical pipe, exhaust fans disposed at the bottom of the vertical pipe and the bottom of the inclined pipes, and a protective component disposed at the top of the vertical pipe.
[0012] Preferably, the protective component includes a rainproof canopy disposed on the top of the vertical pipe, the rainproof canopy being umbrella-shaped, and a plurality of arc-shaped filters being embedded in the top of the vertical pipe.
[0013] Preferably, a filter cylinder is sleeved on the bottom of the T-shaped disk, and a limiting head is threadedly connected to the bottom of the T-shaped disk, with the side wall of the limiting head in contact with the filter cylinder.
[0014] Preferably, a booster fan is provided at the end of the U-shaped tube away from the air intake hood, and an electric heating wire is provided in the middle of the U-shaped tube.
[0015] Preferably, the top of the U-shaped tube is provided with a protective top, and the top of the U-shaped tube is provided with a protective mesh.
[0016] Preferably, a second electric push rod is bolted to the bottom of the rainproof roof, and a baffle is fixedly connected to the output end of the second electric push rod.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application incorporates an air intake mechanism. During this process, the soil layer pre-treats the incoming air. The bottom of the U-shaped pipe is buried inside the soil, utilizing the natural temperature buffering effect of the soil to regulate the temperature of the incoming air (preheating in winter and pre-cooling in summer). This allows for the delivery of low-temperature airflow into the sheep pen in summer and warm airflow into the sheep pen in winter. A first electric push rod drives the T-shaped plate to move up and down, opening or closing the connection port between the U-shaped pipe and the air intake hood. In this way, fresh air is automatically delivered into the sheep pen. By deeply burying the bottom of the U-shaped pipe in the soil, the pre-cooling / preheating of the air by the soil is utilized to deliver low-temperature or warm airflow into the sheep pen, reducing the energy consumption of traditional temperature control equipment and lowering breeding costs. At the same time, the closure control of the top of the U-shaped pipe controls the ventilation.
[0019] 2. This application utilizes an exhaust system. A vertical pipe located in the center of the roof serves as the main exhaust channel, while two inclined pipes on either side act as auxiliary exhaust channels. Exhaust fans are installed at the bottom of all three systems, vertically drawing hot air from the top of the sheepfold. Utilizing thermal buoyancy, the airflow is accelerated upwards. Through the action of these three exhaust fans, polluted air inside the sheepfold is discharged through the vertical pipe. The gas passes through an arc-shaped filter. The extension and retraction of a second electric push rod moves a baffle above or below the arc-shaped filter. When the baffle is below the filter, the vertical pipe is closed, preventing air from escaping from the sheepfold, especially in winter, thus avoiding the loss of hot air. This automated process discharges polluted air from the sheepfold, reducing the concentration of harmful gases such as carbon dioxide and ammonia. Simultaneously, it controls the closure of the vertical pipe to prevent the loss of hot air from the sheepfold at low temperatures. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1 to 5 This utility model provides a technical solution:
[0030] A ventilation and air exchange control device for sheep sheds includes a sheep shed body 1, which includes a frame 2 and a roof 3. Air intake mechanisms 4 are provided on both sides of the frame 2, and an exhaust mechanism 5 is provided on the top of the roof 3.
[0031] The air intake mechanism 4 includes a U-shaped tube 41, with both ends of the U-shaped tube 41 located on both sides of the frame 2. The bottom of the U-shaped tube 41 is located inside the soil below the frame 2. An air intake hood 42 is provided at one point of the U-shaped tube 41. A blower 43 is provided inside the air intake hood 42. The air intake hood 42 is located on the outside of the frame 2. A closing component 44 is provided at one end of the U-shaped tube 41.
[0032] Specifically, such as Figure 3 As shown, the closing assembly 44 includes a top cover 441 disposed at one end of the U-shaped tube 41. A first electric push rod 442 is bolted to the top of the top cover 441. A T-shaped disk 443 is fixedly connected to the output end of the first electric push rod 442. The T-shaped disk 443 is movably disposed at one end of the U-shaped tube 41 and at one end of the air intake cover 42.
[0033] Specifically, such as Figure 3As shown, a filter cylinder 6 is sleeved on the bottom of the T-shaped disk 443, and a limiting head 7 is threadedly connected to the bottom of the T-shaped disk 443. The side wall of the limiting head 7 is in contact with the filter cylinder 6.
[0034] Specifically, such as Figure 3 As shown, a booster fan 8 is provided at the end of the U-shaped tube 41 away from the air intake hood 42, and an electric heating wire 9 is provided in the middle of the U-shaped tube 41.
[0035] Specifically, such as Figure 3 As shown, a protective top 10 is provided on the top of the U-shaped tube 41, and a protective mesh 11 is provided on the top of the U-shaped tube 41.
[0036] During use, the soil layer pre-treats the incoming air. The bottom of the U-shaped pipe 41 is buried in the soil, utilizing the natural temperature buffering effect of the soil to regulate the temperature of the incoming air (preheating in winter and pre-cooling in summer). This allows for the delivery of low-temperature airflow into the sheep pen 1 in summer and warm airflow into the sheep pen 1 in winter, reducing energy consumption. The blower 43 inside the air intake hood 42 draws outside air into the U-shaped pipe 41, and the booster fan 8 further increases the airflow pressure, ensuring that air can be delivered into the sheep pen 1 through the U-shaped pipe 41, overcoming the problem of insufficient power in traditional natural ventilation. The filter cartridge 6 fitted at the bottom of the T-shaped plate 443 filters the air and intercepts particulate matter. The electric heating wire 9 provides auxiliary heating for the incoming air in winter, preventing cold air from directly entering the sheep pen 1 and causing stress to the sheep. The protective top 10 and protective mesh 11 on the top of the U-shaped pipe 41 block rainwater and debris. To prevent pests and insects from entering the pipes and to avoid contamination or equipment damage, when the U-shaped pipe 41 and the air inlet hood are closed, the first electric push rod 442 drives the T-shaped disk 443 to move up and down, opening or closing the connection port between the U-shaped pipe 41 and the air inlet hood. When the electric push rod retracts, the T-shaped disk 443 moves away from the port of the U-shaped pipe 41, opening the air intake channel. When the electric push rod extends, the T-shaped disk 443 is located below the air inlet hood, sealing the U-shaped pipe 41 to prevent rain, snow, and pests from entering the pipes, while also reducing heat loss in winter. In this way, fresh air from outside is automatically delivered to the interior of the sheepfold 1. The bottom of the U-shaped pipe 41 is buried deep in the soil, and the soil is used to pre-cool / preheat the air, thus delivering low-temperature or warm airflow into the interior of the sheepfold 1, reducing the energy consumption of traditional temperature control equipment and lowering breeding costs. At the same time, the closure control of the top of the U-shaped pipe 41 controls the ventilation.
[0037] Specifically, such as Figure 4 As shown, the exhaust mechanism 5 includes a vertical pipe 51 located in the middle of the roof 3, with inclined pipes 52 fixedly installed on both sides of the vertical pipe 51. Exhaust fans 53 are installed at the bottom of both the vertical pipe 51 and the bottom of the inclined pipes 52, and a protective component 54 is installed at the top of the vertical pipe 51.
[0038] Specifically, such as Figure 5As shown, the protective component 54 includes a rainproof top 541 disposed on the top of the vertical tube 51. The rainproof top 541 is umbrella-shaped, and multiple arc-shaped filters 542 are embedded in the top of the vertical tube 51.
[0039] Specifically, such as Figure 5 As shown, a second electric push rod 12 is bolted to the bottom of the rainproof top 541, and a baffle 13 is fixedly connected to the output end of the second electric push rod 12.
[0040] In use, the vertical pipe 51, located in the middle of the roof 3, serves as the main exhaust channel, while the two inclined pipes 52 on either side serve as auxiliary exhaust channels. Each of the three is equipped with an exhaust fan 53 at its bottom, which vertically draws hot air from the top of the sheepfold 1, using thermal buoyancy to accelerate the airflow upwards. Through the action of the three exhaust fans 53, polluted air inside the sheepfold 1 is discharged through the vertical pipe 51. The gas passes through the arc-shaped filter 542 before being discharged. A rainproof roof 541 protects the top of the vertical pipe 51, and the arc-shaped filter 542 prevents external insects from entering the interior of the vertical pipe 51. The extension and retraction of the second electric push rod 12 causes the baffle to move to the upper and lower positions of the arc-shaped filter 542. When the baffle is below the arc-shaped filter 542, the vertical pipe 51 is in a closed state, which can prevent the air inside the sheepfold 1 from being discharged. Especially in winter, it can prevent the loss of hot air inside the sheepfold. In this way, the polluted air inside the sheepfold 1 is discharged automatically, thereby reducing the concentration of harmful gases such as carbon dioxide and ammonia inside the sheepfold. At the same time, the vertical pipe 51 is closed to prevent the loss of hot air inside the sheepfold 1 at low temperatures.
[0041] By adopting the above technical solution, the problems of existing sheepfold ventilation and deodorization devices being unable to deliver cool or warm air into the sheepfold when the temperature is high or low, as well as the inability to perform closed-loop control of ventilation and air supply, have been solved.
[0042] Working principle: In use, the soil layer first pre-treats the incoming air. The bottom of the U-shaped pipe 41 is buried in the soil, utilizing the natural temperature buffering effect of the soil to regulate the temperature of the incoming air (preheating in winter and pre-cooling in summer). This allows for the delivery of low-temperature airflow into the sheep pen body 1 in summer and warm airflow into the sheep pen body 1 in winter, reducing energy consumption. The blower 43 inside the air intake hood 42 draws external air into the U-shaped pipe 41, and the booster fan 8 further increases the airflow pressure, ensuring that air can be delivered to the sheep pen body 1 through the U-shaped pipe 41. When the U-shaped pipe 41 and the air intake hood are closed, the first electric push rod 442 drives the T-shaped disk 443 to move up and down, opening or closing the connection port between the U-shaped pipe 41 and the air intake hood. When the electric push rod retracts, the T-shaped disk 443 moves away from the U-shaped pipe 41. Port 1, air intake channel open, electric push rod extended, T-shaped plate 443 located below air intake hood, to block U-shaped pipe 41, vertical pipe 51 located in the middle of roof 3 as main exhaust channel, and two inclined pipes 52 on both sides as auxiliary exhaust channels, all three are equipped with exhaust fans 53 at the bottom, vertically drawing hot air from the top of sheep pen body 1. Through the action of the three sets of exhaust fans 53, the polluted air inside sheep pen body 1 is discharged through vertical pipe 51. The gas passes through arc-shaped filter screen 542 and is discharged. Through the extension and retraction of the second electric push rod 12, the baffle moves to the upper and lower positions of arc-shaped filter screen 542. When the baffle is below arc-shaped filter screen 542, vertical pipe 51 is in a closed state, which can prevent the air inside sheep pen body 1 from being discharged, especially in winter, to avoid the loss of hot air inside sheep pen, thus realizing the ventilation operation of sheep pen body 1.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 utility model.
