Heat removal device for sleeves for rail fastening testing with efficient airflow removal

Abstract

The invention discloses a heat-removing device efficiently guiding out airflow for a sleeve used for rail fastener detecting. The sleeve is a hollow cover-shaped body; a heat-removing part is arranged on the corresponding sleeve; one end, which is communicated with an opening formed in a heat-resisting slot further from an airflow channel, of the heat-resisting slot is greater than other parts of the heat-resisting slot; and one end of a baffle plate is provided with a bent part extending towards a first hollow chamber. The heat-removing device avoids the problems that connection is unstable due to the fact that the heat-removing device also heats and deforms along with much heat emitted when video acquisition equipment works, the heat-removing device is complex in structure and inconvenient to erect, only partial heat-removing can be achieved, a communicated structure is more complex, hot airflow generated can repeatedly flow only by virtue of external force, externally-unheated heat exchange gas is not liable to enter the channel, the heat easily and quickly attacks an outer wall, airflow transmission efficiency is low and airflow guiding-out efficiency is low.

Description

technical field [0001] The utility model belongs to the technical field of rail fasteners, in particular to a heat removal device for a sleeve used for rail fastener detection, which can efficiently lead out air flow. Background technique [0002] In the device used for track fastener detection, as an important part of video acquisition, the video acquisition equipment is often hung on the road patrol vehicle, and the line conditions are collected along with the vehicle. The video acquisition equipment is set in the road patrol vehicle, and the specific settings The method is that a frame for positioning the video capture device is provided in the road patrol car, and the video capture device also extends out of the bottom of the car body of the road patrol car for video collection. [0003] In order to facilitate the connection, the sleeve is usually put on the outside of the video capture device and then connected to the frame. Since the sleeve is made of metal material, i...

AI Technical Summary

Problems solved by technology

It avoids the large amount of heat emitted by the video acquisition equipment during work, which causes itself to heat and deform, making the connection unstable, the complex structure of the heat removal device inconvenient to erect, and only partial heat removal. The connected structure is more complicated and requires External force can repeatedly make the generated hot air flow, the external heat exchange gas is not easy to enter the passage, the heat is easy to invade the outer wall very quickly, the air transmission efficiency is low, and the air flow export efficiency is low
