Immersion type boiling scene video monitoring device with active cooling function

Abstract

The invention provides an immersion type boiling scene video monitoring device with an active cooling function. The immersion type boiling scene video monitoring device includes a flange provided witha communicating hole, and a flange cover which is fixedly connected with the flange through a bolt, wherein a glass cylinder is fixed between the flange and the flange cover; a protective shell is mounted in the glass cylinder; a communicating opening is formed in the end, facing the flange, of the protective shell; a camera is installed in the protective shell; an image collecting part of the camera faces the same direction as the communicating opening; and a cooling pipe is further installed at the side end of the protective shell, and the other end of the cooling pipe extends out of the flange, and the inner space of the protective shell communicates with the outside through the cooling pipe. The immersion type boiling scene video monitoring device solves the problems that an existingboiling monitoring device is poor in pressure bearing capacity, and the end face sealing performance is poor and the monitoring working condition is single in the prior art, and injects compressed cooling gas into the cooling pipe to absorb heat and then discharged the heat, so as to enable the camera in a protective shell to continuously and accurately monitor, and meanwhile, the whole device canmonitor boiling scenes at different positions by moving the cooling pipe.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, in particular to an immersion-type boiling scene video monitoring device with active cooling. Background technique [0002] In various fields such as thermal power, nuclear power, and chemical industry, it is necessary to observe the boiling scene of liquid under high temperature and high pressure conditions, and it is also necessary to observe the boiling scene for extreme conditions such as corrosive liquids. [0003] The existing boiling monitoring device has poor pressure bearing capacity and poor sealing performance of the end face, so it cannot be used under high temperature and high pressure conditions, and the existing visualization device can only be used to study the boiling scene of a given heat transfer situation and a given heat transfer tube. At the same time, a separate observation window needs to be set up, which is extremely troublesome to install. The monitoring device ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an immersion-type boiling scene video monitoring device with active cooling to solve the poor pressure bearing capacity of the existing boiling monitoring device proposed in the above-mentioned background technology. , the sealing performance of the end face is poor, and the existing visualization device can only be used to study the boiling scene of a given heat transfer situation and a given heat transfer tube. At the same time, it is necessary to set up a separate observation window, which is very troublesome to install. The tube is fixed as a whole, which is inconvenient to move the monitoring device, and it is inconvenient to observe the boiling scene under unknown working conditions in real time
