Description

Technical Field

[0001] This utility model relates to the field of wind cover installation technology, and in particular to a convenient disassembly and assembly structure for a backflow prevention wind cover for livestock fans. Background Technology

[0002] In the livestock farming industry, a good ventilation system is one of the key factors to ensure the healthy growth of livestock. By installing fans for ventilation, the temperature, humidity and air quality of the farming environment can be effectively controlled. In summer, there are many mosquitoes and flies. When the fans are turned off, they are the most likely channel for mosquitoes and flies to enter, leading to an increase in indoor mosquitoes.

[0003] Currently, the air-collecting duct cover is fixed to the main frame of the fan by adhesive. Under the action of return air, the cover will stick tightly to the outer opening of the air-collecting duct, greatly reducing the entry path of mosquitoes and flies.

[0004] However, using the above method, large-scale breeding farms have a large number of fans, and each maintenance or replacement of the covers requires a lot of manpower and time costs, which is not conducive to the efficient management and operation of breeding farms. Utility Model Content

[0005] The purpose of this utility model is to provide a convenient disassembly and assembly structure for the anti-return air cover of livestock fans, which aims to solve the problem that in the existing technology, large-scale breeding farms have a large number of fans, and each maintenance or replacement of the cover requires a lot of manpower and time costs, which is not conducive to the efficient management and operation of the breeding farm.

[0006] To achieve the above objectives, this utility model provides a convenient disassembly and assembly structure for a livestock fan's anti-return air cover, including a fan main frame and an installation connection unit. The installation connection unit includes a right-angle plate, a slide rail, an arc-shaped seat, a trapezoidal rod, a threaded rod, a knob bracket, protective components, and support components. The installation connection unit is connected to the fan main frame. The right-angle plate is fixedly connected to the fan main frame and located on the outer wall of the fan main frame. The slide rail is fixedly connected to the right-angle plate and located on the inner wall of the right-angle plate. The arc-shaped seat is slidably connected to the slide rail and located on the inner sidewall of the slide rail. The trapezoidal rod is fixedly connected to the arc-shaped seat and located above the arc-shaped seat. The right-angle plate has a threaded hole, which is threadedly engaged with the threaded rod. The knob bracket is fixedly connected to the threaded rod and located above the threaded rod. The threaded rod has a trapezoidal hole, which is rotatably engaged with the trapezoidal rod. The protective component is disposed on the inner sidewall of the fan body frame, and the support component is connected to the fan body frame.

[0007] In use, the anti-backflow cover is placed on the outer wall of the main frame of the blower. Rotating the knob bracket drives the threaded rod to rotate in the threaded hole. Utilizing the characteristics of the thread, the threaded rod is extended. At this time, the trapezoidal hole, in conjunction with the trapezoidal rod, converts the axial rotation of the threaded rod into a driving force that resists the downward displacement of the arc-shaped seat until the anti-backflow cover is clamped. During this process, the support component is used to assist the arc-shaped seat in fixing the anti-backflow cover. This method facilitates the installation of the anti-backflow cover by workers, reduces the manpower and time costs associated with the maintenance and replacement of the anti-backflow cover, and is beneficial to the efficient management and operation of the breeding farm.

[0008] The protective assembly includes a mounting ring, screws, and a protective cover. The mounting ring is detachably connected to the main frame of the fan and is located on the inner side wall of the main frame of the fan. The screws are threadedly connected to the mounting ring and the main frame of the fan in sequence. The protective cover is fixedly connected to the mounting ring and is located on the inner side wall of the mounting ring.

[0009] The mounting ring is secured with the screws, which improves the ease of installing the protective cover. The protective cover can prevent the return air from entering the fan main frame when the return air is drawn back, reducing the occurrence of safety incidents, improving the safety of the fan main frame, and extending the service life of the return air cover.

[0010] The protective component further includes a limiting ring, which is fixedly connected to the main frame of the fan and located on the inner side wall of the main frame of the fan.

[0011] The limiting ring assists in fixing the mounting ring, reducing the workload of installers, improving the installation efficiency of the protective cover, and also sharing the pressure generated by the airflow when the protective cover is working.

[0012] The support assembly includes a convex ring and multiple protrusions. The convex ring is fixedly connected to the main frame of the fan and is located on the outer side wall of the main frame of the fan. The multiple protrusions are respectively fixedly connected to the convex ring and are respectively located on the outer side wall of the convex ring.

[0013] The protrusion above the convex ring can increase the frictional force of the contact with the surface of the arc-shaped seat, thereby enhancing the clamping and fixing force, preventing loosening during use, and improving the clamping stability.

[0014] The convex ring has a rounded chamfer.

[0015] The rounded chamfer is used to prevent sharp edges from scratching operators and the backdraft cover, ensuring the safety of staff and the integrity of the backdraft cover, and reducing maintenance costs.

[0016] This utility model discloses a convenient assembly and disassembly structure for a backflow prevention cover for livestock fans. The backflow prevention cover is fitted onto the outer wall of the fan's main frame. Rotating the knob bracket drives the threaded rod to rotate within the threaded hole. Utilizing the characteristics of the thread, the threaded rod extends. The trapezoidal hole, in conjunction with the trapezoidal rod, converts the axial rotation of the threaded rod into a driving force that resists the downward displacement of the arc-shaped seat until the backflow prevention cover is clamped. During this process, the support assembly assists the arc-shaped seat in fixing the backflow prevention cover. This method facilitates the installation of the backflow prevention cover by workers, reducing the significant manpower and time costs associated with its maintenance and replacement, and promoting efficient management and operation of livestock farms.
