[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Example, refer to Figures 1-5 A ventilation device for sheep farming includes a mounting bracket 1 and a ventilation pipe 2 mounted on the mounting bracket 1. A negative pressure fan 5 is installed inside the ventilation pipe 2, and a wire mesh 4 is installed on the inner wall of the ventilation pipe 2. The wire mesh 4 can block birds and some large insects. It also includes: an opening and closing mechanism 6: the opening and closing mechanism 6 is installed inside the ventilation pipe 2; and an adjustment mechanism 3: the adjustment mechanism 3 is connected to one end of the ventilation pipe 2.
[0024] The opening and closing mechanism 6 includes a vertical plate 600 on the inner wall of the ventilation pipe 2. Opening and closing plates 601 are hinged to both sides of the vertical plate 600. A slot 604 is formed in the side wall of the vertical plate 600. A sliding rod 605 is fixed to the inner wall of the slot 604. A slider 606 is sleeved on the outer wall of the sliding rod 605. A spring 607 is sleeved on the outer wall of the sliding rod 605. One end of the spring 607 is connected to the inner wall of the slot 604, and the other end of the spring 607 is connected to the side wall of the slider 606. Both sides of block 606 are hinged with connecting rods 603. One end of each of the two sets of connecting rods 603 is hinged to the side wall of the two sets of opening and closing plates 601. The opening and closing plates 601 are semi-circular in shape. The two sets of opening and closing plates 601 cooperate with the inside of the ventilation pipe 2, so that when the opening and closing plates 601 are closed, the ventilation pipe 2 can be sealed, thereby preventing mosquitoes from entering the ventilation pipe 2 and avoiding the accumulation of a large number of mosquito corpses on the blades of the negative pressure fan 5, thus improving the ventilation effect.
[0025] It should be noted that the opening and closing mechanism 6 can automatically open when ventilation is needed and automatically close when ventilation is not needed, forming a physical barrier to block the entry path of mosquitoes and prevent a large number of mosquito corpses from adhering to the blades of the negative pressure fan.
[0026] The ventilation duct 2 has two sets of limiting plates 608 on its side wall. Each set of limiting plates 608 has an electromagnet 609 on its side wall. Each set of opening and closing plates 601 has a magnet 602 on its side wall that cooperates with the electromagnet 609.
[0027] It should be noted that the limiting plate 608 can limit the opening and closing plate 601. With the cooperation of the electromagnet 609 and the magnetic block 602, the opening and closing plate 601 can be tightly attached to the limiting plate 608, further improving the sealing performance. The electromagnet 609 and the negative pressure fan 5 are both electrically connected to an external controller (this is prior art). When the controller controls the negative pressure fan 5 to work, the electromagnet 609 is de-energized, so that the negative pressure air force can open the opening and closing plate 601 to achieve ventilation. When ventilation is not needed, the controller controls the negative pressure fan 5 to stop working. At this time, the electromagnet 609 is energized. When the spring force of the spring 607 drives the opening and closing plate 601 to reset and close, the magnetic block 602 can quickly attract the electromagnet 609, which can quickly close the plate. At the same time, it can avoid the problem of the opening and closing plate 601 rotating back and forth due to the spring force of the spring 607, thus improving the stability of the closure.
[0028] The regulating mechanism 3 includes a regulating pipe 300 at one end of the ventilation pipe 2, a connecting block 301 on the side wall of the regulating pipe 300, and an electric telescopic rod 302 hinged to the side wall of the mounting bracket 1. One end of the electric telescopic rod 302 is hinged to the side wall of the connecting block 301. The regulating pipe 300 is a corrugated telescopic hose and is made of nylon material.
[0029] It should be noted that the regulating pipe 300 can be bent without being damaged, thus enabling the electric telescopic rod 302 to work. The electric telescopic rod can adjust the tilt angle of the regulating pipe 300, thereby flexibly adapting to the complex environment within the farm.
[0030] The working principle of this ventilation equipment for sheep farming is as follows: The ventilation pipe 2 is installed at the appropriate ventilation opening of the farm using the mounting bracket 1, with one end of the ventilation pipe 2 facing the external environment. During ventilation, the negative pressure fan 5 generates strong suction through high-speed operation, expelling polluted air from the farm. At this time, the electromagnet 609 is de-energized, allowing the expelled air to compress the opening and closing plate 601. The opening and closing plate 601 then compresses the connecting rod 603, which in turn moves the slider 606 on the outer wall of the slide rod 605. The slider 606 compresses the spring 607, opening the ventilation pipe 2 and enabling ventilation. When ventilation is not needed, the controller stops the negative pressure fan 5. The electromagnet 609 is then energized. When the spring 607 causes the opening and closing plate 601 to reset and close, the magnetic block 602 quickly adheres to the electromagnet 609, quickly closing the plate and forming a physical barrier to block mosquitoes from entering and prevent a large number of mosquito carcasses from adhering to the blades of the negative pressure fan 5.
[0031] The extension and retraction of the electric telescopic rod 302 can cause the regulating pipe 300 to bend, thereby adjusting the tilt angle of the regulating pipe 300 and changing its orientation, so as to flexibly adapt to the complex environment in the farm.
[0032] It should be noted that the specific models and specifications of the negative pressure fan and electromagnet need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.
[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
