Description

Technical Field

[0001] This utility model relates to the field of livestock equipment technology, and in particular to a sheep pen ventilation device. Background Technology

[0002] There are many techniques for raising sheep, such as pen-raising. Pen-raised sheep consume less energy and gain weight very quickly. They can be fed pasture and hay in normal times, and a small amount of concentrate can be added during late pregnancy and breeding season. In winter, when the grass is dry, they can be fed bean stalks, sweet potato vines, corn stalks, etc., which can meet the nutritional needs of sheep and promote the growth of lambs.

[0003] Ventilation in sheep pens plays a crucial role in the healthy growth of sheep. Good ventilation effectively removes harmful gases such as ammonia and hydrogen sulfide produced inside the pen, reduces humidity, and minimizes the growth of bacteria and viruses, thus creating a suitable growing environment for the sheep. However, in practice, most existing sheep pens are designed with a closed bottom and an open top, resulting in poor ventilation. Especially during the rainy season, dampness easily breeds bacteria, and a poor growing environment is detrimental to sheep farming, thereby reducing the practicality of the sheep pens. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies in the existing technology by proposing a sheep pen ventilation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sheep pen ventilation device includes a protective frame and a suction fan. The suction fan is disposed within the protective frame and has an upward-facing air outlet. A telescopic pipe is provided at the air outlet. A transition chamber is provided at the top of the telescopic pipe. The transition chamber is connected to an air outlet pipe. An exhaust port is provided at the end of the air outlet pipe and extends outside the sheep pen.

[0007] Furthermore, the protective frame includes a base plate, side frames, and an opening / closing cover. The side frames are fixedly connected to the base plate and form a receiving cavity. The opening / closing cover has a circular opening for the passage of the telescopic tube.

[0008] Furthermore, the opening and closing cover includes two sets of symmetrically arranged movable plates. The edges of the movable plates are hinged to the side frame. The movable plates are provided with semi-circular openings. The semi-circular openings on the two sets of movable plates form a circular opening. An arc-shaped positioning plate is fixedly connected above the semi-circular opening.

[0009] Furthermore, mounting holes are provided at the four corners of the base plate, and shock-absorbing rubber pads are provided in the mounting holes. Threaded steel sleeves are embedded in the shock-absorbing rubber pads, and support columns are threadedly connected to the threaded steel sleeves.

[0010] Furthermore, the side frame is provided with a vertically arranged slot, and a filter plate is detachably installed in the slot. Reinforcing rods are fixedly connected around the filter plate.

[0011] Furthermore, an air quality sensor is installed inside the transition chamber. The air quality sensor is electrically connected to the control module of the suction fan. The air quality sensor is used to monitor the concentration of ammonia and hydrogen sulfide in the air inside the transition chamber and automatically adjust the speed of the suction fan according to a preset threshold.

[0012] Furthermore, a hanging ring is fixedly connected to the top of the transition compartment, and the hanging ring is used for hoisting onto the roof of the sheep pen. Beneficial effects

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Reference Figures 1-3 A sheep pen ventilation device includes a protective frame 5 and a suction fan. The suction fan is installed inside the protective frame 5 and has an upward air outlet. A telescopic pipe 4 is installed at the air outlet. A transition chamber is installed at the top of the telescopic pipe 4. The transition chamber is connected to an air outlet pipe 3. An exhaust port 1 is installed at the end of the air outlet pipe 3 and extends out of the sheep pen.

[0024] The protective frame 5 and the suction fan are placed in the lower middle position of the sheep pen. The suction fan efficiently exhausts the polluted air in the lower middle of the sheep pen. The suction fan is set inside the protective frame 5, which can effectively isolate the sheep pen. This protective structure can also prevent the sheep from accidentally touching the suction fan, thus improving the safety and stability of the equipment operation.

[0025] The upward-facing exhaust vent of the suction fan, together with the telescopic pipe 4, transition chamber, exhaust pipe 3, and the vent 1 extending outside the sheep pen, forms a ventilation path. The telescopic pipe 4 can be flexibly adjusted in length according to actual installation needs, making it easy to adapt to different sheep pen layouts; the transition chamber allows airflow to be buffered within it and provides installation space for the exhaust pipe 3; the exhaust pipe 3 and vent 1 efficiently exhaust polluted air from the sheep pen, effectively reducing the concentration of harmful gases such as ammonia and hydrogen sulfide in the sheep pen, improving air circulation efficiency, and creating a fresh and healthy growing environment for the sheep.

[0026] In his preferred embodiment, the protective frame 5 includes a base plate, a side frame, and an opening and closing cover. The side frame is fixedly connected to the base plate and forms a receiving cavity. The opening and closing cover has a circular opening for the telescopic tube 4 to pass through.

[0027] Specifically, the opening and closing cover includes two sets of symmetrically arranged movable plates. The edges of the movable plates are hinged to the side frame. The movable plates have semi-circular openings. The semi-circular openings on the two sets of movable plates form a circular opening. An arc-shaped positioning plate is fixedly connected above the semi-circular opening.

[0028] The opening and closing cover uses two sets of symmetrically arranged movable plates, the edges of which are hinged to the side frame. Opening and closing is achieved by rotation. This structure allows operators to easily access the suction fan without disassembling the entire protective frame 5, simply by opening the movable plates, greatly simplifying the installation and maintenance process and saving manpower and time costs.

[0029] The semi-circular openings on the movable plate are spliced ​​together to form a circular opening, which is suitable for the telescopic pipe 4 to pass through. The arc-shaped positioning plate above the semi-circular opening can accurately position and limit the telescopic pipe 4, preventing it from shaking or shifting during the operation of the device, and ensuring the stability of the ventilation system connection.

[0030] Specifically, mounting holes are provided at the four corners of the base plate, and shock-absorbing rubber pads are installed in the mounting holes. Threaded steel sleeves are embedded in the shock-absorbing rubber pads, and support columns 6 are connected to the threads inside the threaded steel sleeves.

[0031] The installation of shock-absorbing rubber pads effectively absorbs the vibrations generated by the suction fan during operation. In sheep pen environments, the continuous operation of the suction fan produces high-frequency vibrations. If these vibrations are directly transmitted to the ground, they not only cause noise and disrupt the normal activities of the sheep, but may also lead to loosening of equipment components and wear of connections. The shock-absorbing rubber pads, through their elastic deformation, buffer vibration energy, significantly reducing the transmission of vibrations to the sheep pen floor. This effectively reduces operating noise, creating a quiet growing environment for the sheep, while also extending the equipment's lifespan and reducing maintenance costs due to vibration-induced malfunctions.

[0032] Specifically, a vertically arranged slot 8 is provided on the side frame, and a filter plate 7 is detachably installed in the slot 8. Reinforcing rods are fixedly connected around the filter plate 7.

[0033] The filter plate 7 is detachably installed in the slot 8, facilitating daily maintenance. The filter plate effectively filters the air entering the ventilation system. Sheep pens contain a large amount of wool, dust, and feed debris. If these impurities directly enter the suction fan or ventilation ducts, they can easily cause blockages, affecting the fan's operational efficiency and even damaging components. The filter plate 7 intercepts these impurities, purifying the air entering the system, ensuring stable operation of the suction fan and ventilation system, and reducing pollutants released into the outside air, thus minimizing the impact on the surrounding environment.

[0034] In his preferred embodiment, an air quality sensor is installed in the transition chamber. The air quality sensor is electrically connected to the control module of the suction fan. The air quality sensor is used to monitor the concentration of ammonia and hydrogen sulfide in the air in the transition chamber and automatically adjust the speed of the suction fan according to a preset threshold.

[0035] The air quality inside sheep pens changes dynamically with time, sheep activity, and feed feeding, making it difficult for traditional ventilation systems to flexibly adjust ventilation intensity according to actual needs. This design, however, uses preset thresholds to immediately transmit signals to the exhaust fan control module when ammonia or hydrogen sulfide concentrations exceed safe levels. The control module automatically increases the exhaust fan speed, boosting ventilation and quickly expelling polluted air from the sheep pen. When the concentrations drop to a safe level, it automatically reduces the exhaust fan speed, maintaining the ventilation system in an appropriate operating state. This dynamic and precise adjustment of ventilation intensity ensures consistently good air quality inside the sheep pen.

[0036] In his preferred embodiment, a hanging ring 2 is fixedly connected to the top of the transition compartment, and the hanging ring 2 is used for hoisting onto the ceiling of the sheep pen. By hoisting the transition compartment onto the ceiling of the sheep pen using the hanging ring 2, there is no need for complex foundation construction on the ground or drilling holes in the walls. Only ropes, hoisting straps and other tools are needed to connect the hanging ring 2 to the fixed point on the ceiling, which can quickly complete the installation and positioning of the transition compartment, greatly shorten the installation time, reduce the labor and material costs of installation and construction, and also reduce the interference with the normal breeding activities of the sheep pen during the installation process.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
