Description

Technical Field

[0001] The utility model relates to a laser rangefinder cooling technology, in particular to a laser rangefinder cooling device. Background Art

[0002] Laser rangefinders are mainly used to detect the thickness of sintered material surfaces. The temperature of sintered materials is high during on-site production. For existing laser rangefinders, if the temperature on site is high during use, the laser rangefinder will be in a high temperature environment for a long time, which will damage the internal components of the laser rangefinder, thereby affecting the accuracy of the measurement. Moreover, if the temperature of the object being measured is very high, such as molten metal, the object being measured will generate strong thermal radiation to the laser rangefinder, which will also damage the laser rangefinder. Therefore, a laser rangefinder cooling device was developed. Utility Model Content

[0006] As a further improvement of the present invention, cooling gas is passed through both the first air intake pipe and the second air intake pipe.

[0007] As a further improvement of the present invention, the cooling gas is nitrogen.

[0008] As a further improvement of the utility model, a cooling space is formed between the sealing cover and the shell of the laser rangefinder to facilitate the passage of cooling gas.

[0009] As a further improvement of the utility model, a mounting plate is fixed in the sealing cover, the laser rangefinder is arranged on the mounting plate, and a plurality of air holes are opened on the mounting plate. The arrangement of the mounting plate not only facilitates the fixation of the laser rangefinder, but also can increase the residence time of the cooling gas in the first air inlet pipe and the second air inlet pipe in the sealing cover, increase the cooling effect of the cooling gas on the laser rangefinder, and at the same time can reduce the amount of cooling gas used, saving costs.

[0010] As a further improvement of the present invention, the ventilation holes are circular holes or polygonal holes.

[0011] The beneficial effects of the utility model are as follows: the utility model uses nitrogen gas to cool down the laser rangefinder by inflow and outflow in a closed space, and at the same time, performs temperature detection according to the temperature measuring thermal resistor, and can control the flow of nitrogen gas at any time, saving nitrogen gas during shutdown and maintenance. The setting of the sealing cover is not only convenient for cooling down the laser rangefinder, but also can protect the laser rangefinder. BRIEF DESCRIPTION OF THE DRAWINGS
