The invention discloses a stable
laboratory monitoring device which comprises a mounting box, a partition plate, a first motor, a transmission rod, a limiting block, cooling fan blades, a first fixingplate, a telescopic rod, a second fixing plate, an anti-skid pad, a protection device
whole body, a second motor, a rotating shaft, a monitoring device main body, a pin hole, a ventilation opening and a
pressure reduction spring. According to the invention, the mounting box and the protection device are integrally arranged, so that the problems that in the prior art, the monitoring device is prone to failure due to power failure or other factors in a laboratory in special environments such as high temperature,
high pressure or ultralow temperature, vacuum, strong
magnetism, microwaves,
radiation,
high voltage and high rotating speed, and then the monitoring alarm effect of an Internet-of-Things computer connected with the monitoring device fails are solved. And through arrangement of a first motor and heat dissipation fan blades, an effective heat dissipation effect on the monitoring device main body is achieved, so that the service life of the whole device is prolonged.
