The invention relates to a positive-pressure air film protection holder and belongs to the technical field of monitoring and sampling device. The holder comprises a holder seat and a holder pole. The holder pole is inserted into an upper shell and fixedly connected with the top end of the upper shell; a through hole is arranged at the tube wall of the holder pole which is arranged in the upper shell; an air inlet tube is arranged at the side direction of the holder pole; a lower shell with an upward opening is arranged in the upper shell and a window is arranged at a base disk of the lower shell; a universal rotating mechanism which is in hinged connection with a connecting arm is arranged at the lower end of the holder pole, a connecting rod is arranged at the connecting arm and the connecting rod is arranged at a bracket at the base disk. The positive-pressure air film of the invention is formed by externally-supplied relatively clean air current and has effective corrosion and dust resistance capabilities for probes.
Description
technical field [0001] The invention belongs to the technical field of monitoring and sampling devices, and relates to a device that uses a positive pressure air film to effectively prevent dust, prevent corrosion and self-clean the video or other probes that must be placed in harsh environments and can be rotated as required. Background technique [0002] Modern monitoring and detection technology has made great progress, and its application is becoming wider and wider, which also brings about some problems that need to be solved as a result of technological progress. If there are harsh environments such as corrosive gas and dust, video or other probes, hereinafter referred to as monitoring the corrosion, dustproof and self-cleaning of the sampling device are more prominent problems. Usually these devices used for on-site real-time monitoring and sampling do not have a high protection level. Even if there are some high protection levels such as waterproof and dustproof, the...
