A power-off protection system of a hypobaric chamber

Abstract

The invention provides a power-off protection system of a hypobaric chamber. The system comprises a chamber body; a cabin is arranged inside the chamber body; a first air pipe, a second air pipe and athird air pipe are penetrated through the chamber body; a solenoid valve is arranged on the first air pipe; a portion, inside the chamber body, of the second air pipe is provided with a first hand-operated valve; a portion, outside the chamber body, of the third air pipe is provided with a second hand-operated valve; and the solenoid valve is electrically connected with a power supply system. According to the invention, the three air pipes are arranged; one of the three air pipes is provided with the solenoid valve; and the other two are provided with the hand-operated valves. In the power outage, the solenoid valve is automatically opened, and the hand-operated valves can be manually opened inside and outside the chamber body, separately, to form multiple protection on users of the chamber body.

Description

technical field [0001] The invention relates to a low pressure cabin, in particular to a power-off protection system for a low pressure cabin. Background technique [0002] The hypobaric chamber is a device that can form a hypobaric and hypoxic environment. It relies on the pumping device to create a hypobaric and hypoxic state in the chamber, and can adjust the air pressure in the chamber as needed to simulate a high-altitude environment. Oxygen endurance; especially for mountaineering enthusiasts and soldiers, allowing them to experience high-altitude environments at low altitudes. [0003] At present, with the improvement of science and technology and the change of research direction, researchers have found that the hypobaric chamber can not only simulate the high-altitude environment, but also has many benefits to the human body, such as improving the oxygen transport function of vascular tissue and improving cardiopulmonary function. Wait. [0004] Because the current...

Problems solved by technology

[0004] Because the current low pressure chamber is not widely used, its structural characteristics are often designed to deal with professionals and soldiers, and its protection measures are not perfect. Therefore, how to make the low pressure chamber suitable for ordinary people, especially in the How to ensure the safety of users is the content that needs to be studied under the condition of electricity
