An electrical fire monitoring device

Abstract

The invention relates to an electrical fire monitoring device, which comprises a mounting box. First vents are opened in a left side wall of the mounting box. Second vents are opened in a right side wall of the mounting box. A rotating shaft is rotatably connected onto the left side wall in the mounting box. Negative pressure blades are fixed on the rotating shaft. A stepping motor is fixed in themounting box. An output shaft of the stepping motor is fixedly connected with the rotating shaft. A temperature sensor for controlling the power of the stepping motor is fixed in the mounting box. Acooling water pipe is fixed in the mounting box. A slide valve is mounted on the cooling water pipe. A starting mechanism for opening the slide valve is mounting on the mounting box. Compared with theprior art, the scheme improves the cooling efficiency through the arrangement of the cooling water pipe, the negative pressure blades, the starting mechanism and the stepping motor; also achieves adjustment of the cooling efficiency in the mounting box; and further achieves the cooling mode switching of the air cooling to the combination of air cooling and water cooling.

Description

Technical field [0001] The invention belongs to the field of monitoring equipment, and particularly relates to an electrical fire monitoring equipment. Background technique [0002] Electrical equipment is mostly expensive, and it is not guarded by anyone outside, and often becomes a target for criminals to steal; and due to the influence of unstable voltage, high temperature, or rain and water, if it cannot be cleaned or cut off in time, electrical equipment May be damaged or cause a fire; therefore, during the operation of outdoor electrical equipment, electrical fire monitoring equipment needs to be used to monitor its safety hazards. The structure of electrical fire monitoring equipment generally includes a mounting box, which is installed in the mounting box. The dedicated hardware for monitoring functions can make the entire electrical fire monitoring equipment run by energizing the hardware. [0003] When the electrical fire monitoring equipment is running, the entire elect...

Problems solved by technology

[0002] Most of the electrical equipment is expensive, and it is placed outdoors without anyone guarding it, so it often becomes the target of criminals stealing it; and due to the influence of factors such as unstable voltage, high temperature, or rain and water, if it cannot be cleaned in time or the power is cut off, the electrical equipment will be damaged. It may be damaged or cause a fire; therefore, during the operation of outdoor electrical equipment, it is necessary to monitor its potential safety hazards through electrical fire monitoring equipment. The structure of electrical fire monitoring equipment generally includes an installation box, which has a Special hardware for monitoring function, by powering on the hardware, the entire electrical fire monitoring equipment can be operated

[0003] When the electrical fire monitoring equipment is running, the entire electrical fire monitoring equipment will generate a lot of heat, so it is necessary to dissipate heat from the electrical fire monitoring equipment. In the past, the way to dissipate heat from the electrical fire monitoring equipment was to directly open cooling holes on the installation box , dissipate heat through the heat dissipation holes, the problem of this heat dissipation method is that the heat dissipation efficiency is slow, and if the power of the electrical fire monitoring equipment is large, if the heat cannot be dissipated in time, it is easy to damage the hardware in the electrical fire monitoring equipment, causing unnecessary loss
