Power-free rapid ventilation system of workshop

Abstract

The invention discloses a power-free rapid ventilation system of a workshop. The power-free rapid ventilation system of the workshop comprises a ventilator, a wind-driven wheel, a wind direction plate, a main shaft, a bevel gear a, a bevel gear b, a supporting frame, a rotary disc, a driving shaft, a transmission mechanism c and a going barrel. The ventilator is installed in a ventilation passage at the top of the workshop. The bevel gear b is installed on a ventilator shaft and engaged with the bevel gear a. The rotary disc is arranged at a top end outlet of the ventilation passage, and the bottom surface of the rotary disc is provided with a guide groove corresponding to the ventilation passage. The supporting frame is arranged on the rotary disc. The wind-driven wheel is installed on the main shaft. The main shaft is installed on the supporting frame through a bearing. The wind direction plate is arranged on the supporting frame and on the side symmetric to the wind-driven wheel. The two ends of the transmission mechanism c are connected with a transmission shaft and the main shaft correspondingly. The going barrel is arranged between the driving shaft and the transmission shaft, and the two ends of a spring shaft are connected with the transmission shaft and the driving shaft correspondingly through an overrunning clutch. The bevel gear a is installed on the driving shaft. The work area of the wind-driven wheel is large, and the wind-driven wheel can be driven to rotate by even small natural wind.

Description

technical field [0001] The invention relates to the technical field of factory building exhaust equipment, in particular to a powerless rapid ventilation system for a factory building. Background technique [0002] Some harmful gases will be produced during the industrial manufacturing process in the workshop. If these gases cannot be discharged in time and thoroughly, they will pollute the air in the workshop and endanger people's health. Therefore, a properly designed exhaust system needs to be installed in the workshop. The existing non-powered fan is a device that uses the principle of natural wind and air convection to accelerate and transform the air flow in the parallel direction into a vertical air flow from bottom to top, so as to improve the indoor ventilation effect. It can effectively discharge the hot, dirty or dusty air in the workshop, the indoor temperature will drop, naturally cool down and convert fresh air, so as to achieve the effect of adjusting tempera...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem that the existing unpowered fan cannot meet the working requirements, the present invention develops a fast unpowered ventilation system for a factory building. Even in the case of poor wind conditions, the ventilation system can maintain the speed of the ventilation fan and ensure the air inside the factory building. quality
