However, this device cannot adjust the airflow speed and temperature according to the temperature and humidity inside the livestock shed, thus failing to provide suitable air conditions for livestock to survive. Therefore, the inventors have provided an adjustable livestock pen ventilation device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable ventilation device for livestock pens, which can adjust the ventilation mechanism according to the different temperatures and humidity inside the livestock pens.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An adjustable livestock pen ventilation device includes a livestock pen, a controller installed on the rear side of the interior of the livestock pen, and a ventilation mechanism installed on the exterior of the livestock pen. The ventilation mechanism includes an air inlet pipe embedded and fixed on the left side of the livestock pen, an air inlet fan installed inside the air inlet pipe, and an air outlet pipe embedded and fixed on the right side of the livestock pen, an air outlet fan fixedly installed inside the air outlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This adjustable livestock pen ventilation system uses temperature and humidity sensors to detect the temperature and humidity inside the livestock pen. When the humidity and temperature exceed the set values, the controller starts the intake and exhaust fans via an external power source. Outside air enters the intake duct after being filtered through a filter. When the air temperature inside the livestock pen is low or the humidity is high, the controller can start the electric heating coil via an external power source. As the incoming air passes through the electric heating coil, the air temperature increases, and the warm air is discharged into the livestock pen, gradually increasing the air temperature and decreasing the humidity inside the livestock pen. This achieves the effect of regulating the temperature and humidity inside the livestock pen. At the same time, the exhaust fan rotates to expel the stale air from inside the livestock pen, thus achieving the effect of adjusting the ventilation mechanism according to the different temperature and humidity inside the livestock pen.

[0013] In addition, this adjustable livestock pen ventilation device starts a second motor through an external power supply. The output end of the second motor drives the second threaded rod to rotate, thereby driving the moving block to move up and down. At the same time, the moving block slides along the surface of the sliding rod, which guides the movement of the cleaning brush and drives the cleaning brush to move in the same direction, brushing away the dust and impurities on the surface of the filter screen, ensuring the cleanliness of the filter screen surface, and allowing the filter screen to pass through normally, thereby achieving the effect of cleaning the filter screen surface.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] like Figure 1-3 As shown, an adjustable livestock pen ventilation device includes a livestock pen 10. A controller 11 is installed on the rear side of the interior of the livestock pen 10. The controller 11 has a built-in temperature sensor and a humidity sensor. A ventilation mechanism 20 is provided on the exterior of the livestock pen 10. The ventilation mechanism 20 includes an air inlet pipe 201 embedded and fixed on the left side of the livestock pen 10. An air inlet fan 204 is installed inside the air inlet pipe 201. An air outlet pipe 211 is embedded and fixed on the right side of the livestock pen 10. An air outlet fan 212 is fixedly installed inside the air outlet pipe 211. The air inlet fan 204 and the air outlet fan 212 are electrically connected to the controller 11.

[0021] During operation, temperature and humidity sensors detect the temperature and humidity inside the livestock shed 10. When the humidity and temperature exceed the set values, the controller 11 activates the intake fan 204 and the exhaust fan 212 via an external power supply. The intake fan 204 draws outside air into the livestock shed 10, while the exhaust fan 212 expels stale air from inside the shed, thus achieving ventilation. The controller 11 can also control the output speed of the fans as needed to regulate the ventilation rate of the livestock shed 10. Furthermore, the controller 11 can periodically ventilate the livestock shed 10 to ensure fresh air inside, significantly reduce the concentration of harmful gases such as ammonia and hydrogen sulfide, improve air quality, and enhance animal comfort, reduce disease incidence, and increase production efficiency.

[0022] Preferably, a filter screen 202 is fixedly connected to the left side of the air inlet pipe 201, and an electric heating coil 203 is fixedly installed inside the air inlet pipe 201. The electric heating coil 203 is electrically connected to the controller 11. A folded flexible hose 205 is fixedly connected to the right side of the air inlet pipe 201, and an air inlet box 206 is fixedly connected to the right side of the folded flexible hose 205.

[0023] When air is introduced, the filter 202 can filter out sand and dust impurities in the air. When the air temperature inside the livestock shed 10 is low or the humidity is high, the controller 11 can start the electric heating coil 203 through an external power supply. When the incoming air passes through the electric heating coil 203, the air temperature increases. The warm air is discharged into the livestock shed 10, which gradually increases the air temperature inside the livestock shed 10 and gradually decreases the humidity inside the livestock shed 10, thereby achieving the effect of regulating the temperature and humidity inside the livestock shed 10.

[0024] Furthermore, an adjustment box 207 is fixedly connected to the left side of the interior of the livestock shed 10. The interior of the adjustment box 207 is hollow and open on the right side. The upper and lower sides of the interior of the adjustment box 207 are rotatably connected to a first threaded rod 209. An L-shaped block 210 is threadedly connected to the outside of the first threaded rod 209. The L-shaped block 210 includes a horizontal bar and a vertical bar that are vertically connected. The top of the vertical bar is fixedly connected to the air inlet box 206. A first motor 208 is fixedly installed on the top of the adjustment box 207. The output end of the first motor 208 is fixedly connected to the first threaded rod 209. The first motor 208 is electrically connected to the controller 11.

[0025] In use, the controller 11 starts the first motor 208 through an external power supply. The output end of the first motor 208 drives the first threaded rod 209 to rotate, thereby causing the L-shaped block 210 and the air inlet box 206 to move up and down. The folded hose 205 will stretch or contract accordingly as the air inlet box 206 moves, thereby achieving the effect of adjusting the position of the air inlet box 206. The adjustable air inlet box 206 can be adjusted according to actual needs to optimize the ventilation path. By reasonably arranging the air inlets, it can be ensured that fresh air can enter the required area evenly and effectively, improving ventilation efficiency. This helps to improve indoor air quality, reduce the accumulation of air pollutants, and provide people with a healthier and more comfortable living environment.

[0026] refer to Figure 4 A cleaning mechanism 30 is provided on the outer side of the filter screen 202. The cleaning mechanism 30 includes a pair of mirror-arranged connecting boxes 301 fixedly connected to the left and right sides of the front of the filter screen 202. The upper and lower sides of the left connecting box 301 are rotatably connected to a second threaded rod 302. A moving block 303 is threadedly connected to the outer side of the second threaded rod 302. A cleaning brush 305 is fixedly connected to the rear side of the moving block 303. The rear side of the cleaning brush 305 contacts the surface of the filter screen 202. A second motor 304 is fixedly installed on the top of the left connecting box 301. The output end of the second motor 304 is fixedly connected to the second threaded rod 302.

[0027] Preferably, the upper and lower sides of the inside of the right-side connecting box 301 are fixedly connected to a sliding rod 306, and the sliding rod 306 is slidably connected to the moving block 303.

[0028] In use, the second motor 304 is started by an external power supply. The output end of the second motor 304 drives the second threaded rod 302 to rotate, thereby driving the moving block 303 to move up and down. At the same time, the moving block 303 slides along the surface of the sliding rod 306, which guides the movement of the cleaning brush 305 and drives the cleaning brush 305 to move in the same direction, brushing away the dust and impurities on the surface of the filter screen 202, ensuring the cleanliness of the surface of the filter screen 202, and allowing the filter screen 202 to pass through normally, thereby achieving the effect of cleaning the surface of the filter screen 202.

[0029] The working principle of this utility model is as follows: During use, the temperature and humidity sensors detect the temperature and humidity inside the livestock shed 10. When the humidity and temperature exceed the set values, the controller 11 starts the intake fan 204 and the exhaust fan 212 through an external power supply. Outside air enters the interior of the intake duct 201 after being filtered by the filter screen 202. When the air temperature inside the livestock shed 10 is low or the humidity is high, the controller 11 can start the electric heating coil 203 through an external power supply. When the incoming air passes through the electric heating coil 203, the air temperature increases, and the warm air is discharged into the livestock shed 10, causing the air temperature inside the livestock shed 10 to gradually increase and the humidity inside the livestock shed 10 to gradually decrease, thereby achieving the effect of regulating the temperature and humidity inside the livestock shed 10. At the same time, the exhaust fan 212 rotates to discharge the stale air inside the livestock shed 10, thereby achieving the effect of ventilation and air exchange in the livestock shed 10. Furthermore, the controller 11 controls the output speed of the above-mentioned fans as needed to achieve the effect of regulating the ventilation rate of the livestock shed 10.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
