Butterfly door regulating device with self-adaption regulating function

Abstract

The invention discloses a butterfly door regulating device with a self-adaption regulating function. The butterfly door regulating device comprises a supporting frame, a left butterfly door, a right butterfly door and a wind collection barrel. Supports are arranged at the upper end and the lower end of the supporting frame correspondingly. A cushion plate is fixed to each support. The left butterfly door and the right butterfly door are symmetrically arranged between the cushion plates. The left butterfly door and the right butterfly door are connected through a spring and the supporting frame. The wind collection barrel fixed to the supporting frame is arranged on the outer circle of the left butterfly door and the outer circle of the right butterfly door. A nylon rope is arranged between the left butterfly door and the right butterfly door. One end of the nylon rope is fixed to the cushion plate at the upper end, and the other end of the nylon rope penetrates a through hole located in the lower end of the wind collection barrel, extends to the exterior of the wind collection barrel and is pressed through a rope pressing buckle. The butterfly door regulating device is simple in structure, low in production cost and convenient to maintain and clean in the later period; the butterfly doors which are symmetrically arranged are regulated through the nylon rope, and therefore the air volume can be controlled; the plug-in type design is adopted for the wind collection barrel, and cleaning and maintaining in the later period are facilitated.

Description

technical field [0001] The invention relates to a butterfly door adjusting device with self-adapting adjusting function. Background technique [0002] At present, in the intensive, large-scale, and automated standard chicken house farming, the temperature inside the chicken house has become the decisive factor for the success of the breeding. At present, the temperature in the chicken house is mainly reduced by the wet curtain and the 50-inch butterfly fan. The 50-inch butterfly fan plays an extremely important role in the ventilation and cooling of the chicken coop, and is the key factor determining the success or failure of the breeding. At present, the 50-inch butterfly fan on the market generally has the problem that the two butterfly doors cannot fit together when the fan is running, resulting in a certain angle between the butterfly doors, which reduces the ventilation area of ​​the fan, thereby reducing the ventilation volume of the fan. According to the actual test,...

AI Technical Summary

Problems solved by technology

[0003] The existing 50-inch butterfly fan does not comprehensively consider the influence of the airflow inside and outside the chicken house and the rebound airflow between the butterfly doors on the butterfly door, and cannot rely on the fan itself for self-adaptive adjustment, and cannot fundamentally solve the problem that the butterfly door cannot be fitted
