Liquid level detection device and box body with same

Abstract

The invention discloses a liquid level detection device and a box body with the same. The liquid level detection device is provided with two electrode columns inserted into liquid, a preset conductivegap is formed between the two electrode columns, and floating bodies floating up and down along the electrode columns sleeve the two electrode columns. Conduction parts are arranged at the lower endsof the floating bodies and are positioned in the conductive gap; a conduction pin is formed at the tail end of each electrode column, and the width of the bottom of each conduction part is larger than the distance between the two conduction pins so that the electrode column can be conducted. The liquid level detection device disclosed by the invention is used in the box body; a problem that perfluoro(2-methyl-3-pentanone) volatilizes at the high temperature of 49 DEG C under the normal pressure condition can be effectively solved in cooperation with a moisture-proof one-way ventilation assembly; no internal pre-stored pressure feedback is realized in a normal pressure state, and gas leakage after perfluoro(2-methyl-3-pentanone) is volatilized is effectively prevented; and meanwhile, whenthe medicament is reduce due to starting of a fire extinguishing power device, external air enters the box body through the valve body to supplement the pressure, the moisture content of the enteringair is reduced, the volume of the medicament is effectively monitored, and the purpose of monitoring the liquid level in real time is achieved.

Description

technical field [0001] The invention relates to the technical field of new energy fire suppression, in particular to a liquid level detection device and a box having the same. Background technique [0002] Perfluorohexanone is an emerging fire suppression agent in recent years. It is a clear, colorless, odorless liquid and has the characteristics of no environmental pollution, so it has been rapidly promoted. Perfluorohexanone has a boiling point of only 49°C and cannot be mixed with water, which has become the main reason affecting its storage, production and other processes. [0003] The perfluorohexanone fire suppression products currently appearing in the market all adopt the filling, storage and production mode of traditional fire extinguishers that are supercharged with nitrogen, that is, use the sealing technology and pre-pressurization technology of traditional fire extinguishers to complete the relevant production process . The feedback device feeds back the pre-p...

AI Technical Summary

Problems solved by technology

The disadvantage of this kind of product is that once it is started, the whole bottle of agent is sprayed at one time, and the demand for fire extinguishing is completed with a large margin.

Although this invention can realize the measurement of various information such as liquid level, temperature, density, etc. in the filling and storage equipment, it has certain limitations in the liquid level detection inside the small-sized structural box, and its own structure and installation method are complicated, so it cannot be applied small storage tank
