Problems solved by technology

It is inert, colorless, odorless, non-corrosive, non-flammable, and has extremely low temperature. Due to these characteristics, it has potential for fire protection. However, most of the existing methods of using liquid nitrogen are through pipeline injection. The effect is not good, the amount of liquid nitrogen that can be produced is small, and the rapid local fire extinguishing function cannot be achieved, and there is a certain risk of use

Abstract

The invention discloses ejection type high-pressure liquid nitrogen fire rescue equipment. The ejection type high-pressure liquid nitrogen fire rescue equipment comprises a fire rescue assist device,a bottom space is formed in the fire rescue assist device, an ejection space communicating the bottom space with the external space is formed in the upper side of the bottom space, an ejection mechanism is arranged in the bottom space, the ejection mechanism comprises a lifting block, a moving space with an upper opening and a lower opening is formed in the lifting block, and an electromagnet is fixedly arranged in the moving space. According to the ejection type high-pressure liquid nitrogen fire rescue equipment, by means of an ejection mode, a high-pressure liquid nitrogen tank body can beejected out to be used for building a fire rescue channel, liquid nitrogen is ejected out through cooperation of eight ejection pipelines and rotation of the liquid nitrogen tank body, the liquid nitrogen is ejected out quite rapidly, a better local fire extinguishing effect is achieved, a certain ejection stroke can be kept according to adjustment of a shooting angle, safe and stable use of the liquid nitrogen fire rescue equipment is guaranteed, the stable rotating speed of the liquid nitrogen tank during shooting can be guaranteed, and use is quite safe.

Description

technical field [0001] The invention relates to the field related to liquid nitrogen, in particular to an ejection type high-pressure liquid nitrogen fire rescue equipment. Background technique [0002] Liquid nitrogen, liquid nitrogen. It is inert, colorless, odorless, non-corrosive, non-flammable, and has extremely low temperature. Due to these characteristics, it has potential for fire protection. However, most of the existing methods of using liquid nitrogen are through pipeline injection. The effect is not good, the amount of liquid nitrogen that can be produced is small, the function of rapid local fire extinguishing cannot be achieved, and there is a certain risk of use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ejection type high-pressure liquid nitrogen fire rescue equipment to overcome the above-mentioned situation. [0004] The present invention is achieved through the following technical so...
