An environment-friendly smoke exhaust device based on building fire protection

Abstract

The invention discloses an environment-friendly smoke exhaust device based on building fire protection, and relates to the technical field of building fire protection. The invention comprises a shell and a wind guide window, a support plate is fixedly connected to the inner wall of the lower end of the shell; a mounting groove is arranged on the front side plate of the shell above the support plate, and at the same time, a connecting groove is connected to the rear side plate of the shell above the support plate. Exhaust duct; the outer wall of the exhaust duct is fixedly sleeved with a solar panel; wherein, an air guide window is fixedly arranged in the installation groove; the air guide window includes an air guide plate, a connecting plate and a linkage plate, and the air guide plate is vertically A plurality of them are arranged side by side in the direction. The present invention is provided with a series of structures and the mutual cooperation between the structures, so that the device can quickly exhaust smoke in a large range in the building during use. The device has an independent power supply system and has high working stability. It can be used to cool down and extinguish fire protection, play a very good role in protecting itself, and ensure normal use.

Description

technical field [0001] The invention belongs to the technical field of building fire protection, and in particular relates to an environment-friendly smoke exhaust device for building fire protection, which is mainly used for smoke exhaust inside buildings. Background technique [0002] The smoke exhaust device is mainly used for timely discharge when a fire occurs inside the building and a large amount of smoke is generated, so as to avoid excessive smoke inside the building causing a lot of damage to the people inside the building, and to buy a certain time for rescue operations. First of all, the existing The air inlets of the smoke exhaust devices are all fixed, and can only exhaust smoke in fixed areas in the building, and the smoke exhaust efficiency is low. Secondly, most of the power systems of the existing smoke exhaust devices are connected to the building power system, but In the event of a fire, it is necessary to cut off the power of the entire building, which w...

Problems solved by technology

[0003] The purpose of the present invention is to provide an environment-friendly smoke exhaust device based on building fire protection. The expansion and contraction of the electromotive force telescopic rod can drive the synchronous linkage of the whole wind deflector, and then automatically adjust the angle when exhausting smoke to achieve large-scale and rapid smoke exhaust. The setting of the solar panel can convert the light energy into electric energy and store it in the storage battery, which is used for the power consumption of the electrical components in the device to form an independent power supply system. The setting of the liquid carbon dioxide in the carbon dioxide storage tank can damage the device in case of fire When damage is caused, carbon dioxide is ejected to extinguish the fire and cool down, which solves the problem that the existing smoke exhaust device cannot quickly exhaust smoke in a large area in the building, the power system is unstable, and the fire will cause damage to the smoke exhaust device itself, making it unusable The problem
