Problems solved by technology

[0003] However, the laboratory ventilation currently on the market has different requirements for ventilation due to different experiments. Those with low ventilation requirements are usually carried out on ordinary experimental tables with a large operable area, which is easy to operate, and those with relatively high ventilation requirements need to be carried out in a fume hood. When conducting multiple experiments, the experimental operation will be affected due to the limitation of the volume of the fume hood, which will affect the progress of the experiment.

Abstract

The invention discloses a telescopic ventilation system based on laboratory ventilation. A telescopic exhaust assembly is installed at the bottom end of a ventilation pipe, a sliding plate is connected with a guide rail through a sliding connection assembly, a ventilation plate is installed at the bottom end of a connecting pipe, and rubber rings are embedded in the positions, corresponding to thin ropes, of a folding curtain. A precise ventilation assembly is installed at the position, corresponding to the bottom end of the connecting pipe, of the bottom end of the ventilation plate, rotating shaft pipes are installed at the joints of a top pipe, a middle pipe and a bottom pipe in a penetrating mode, and an emergency fire extinguishing assembly is installed at one end of the top face of the ventilation plate. Adjustment and splicing of the telescopic exhaust assembly are utilized to form a ventilation cabinet structure with an adjustable range, and an experiment is facilitated. The precise ventilation assembly further strengthens the small-range ventilation effect, large-range ventilation and small-range ventilation are switched, the sliding connection assembly is used in cooperation with the telescopic exhaust assembly, maintenance is facilitated while movement is smoother, the emergency fire extinguishing assembly effectively extinguishes fire and prevents harmful gas diffusion, and therefore safety is improved.

Description

technical field [0001] The invention relates to the technical field of ventilation systems, in particular to a telescopic ventilation system based on laboratory ventilation. Background technique [0002] Laboratory ventilation is a technology to study and control the influence and damage of laboratory harmful substances on the indoor and outdoor air environment. The ventilation system can be divided into natural ventilation and mechanical ventilation. Mechanical ventilation can be divided into comprehensive ventilation and local ventilation. A way to ventilate the room as a whole. Local ventilation refers to the ventilation method that controls the range of ventilation in places where harmful substances are concentrated, or in local areas where staff often move, such as fume hoods and universal exhaust. Fume hood, atomic absorption hood, etc. [0003] However, the laboratory ventilation currently on the market has different requirements for ventilation due to different expe...
