After the alcohol test is performed on the person to be detected and the person to be detected leaves the device, the PLC controls the ultraviolet lamp tube 32 to be started, the air blowing cover 15 is irradiated with ultraviolet rays, the air outlet cover is sterilized through the ultraviolet rays, and the situation that the use of the device is affected by bacteria on the air outlet cover is avoided.

When the device for preventing drunken construction is used, the intercepting components on two sides of the top plate 2 respectively act on the inlet position and the outlet position of a construction channel, the initial state of the device is realized, two intercepting plates 5 in the intercepting components on the inlet position are far away from each other, so that people can conveniently enter between two vertical plates 4 for inspection, the two intercepting plates 5 in the intercepting components on the outlet position are close to each other, the condition that people do not finish inspection and pass through the device is prevented, when the inspection is carried out, the driving components act on the lifting components on two sides to drive the two detecting plates 10 to move up and down, the camera 11 is utilized to shoot images, the device can conveniently carry out face recognition, and judge whether people carry articles, the alcohol test is conveniently carried out on people through the alcohol test unit, whether an operator is in a drunken state is judged, when the identity of a person to be detected and the person is not drunken, prevent that other personnel from contacting construction machinery, and two interception boards 5 keep away from each other in the exit interception subassembly, the operating personnel who is convenient for legal contacts construction machinery and carries out safe construction operation, and when the testing result is that the identity is illegal, perhaps the identity is legal but operating personnel is in when drunk or carrying article, then the interception board 5 position that leans on together in the exit interception subassembly is fixed, blocks people and contacts construction machinery, and then has guaranteed safe construction.

Compared with the prior art, this device of preventing drunk construction can carry out authentication, drunk test and judge whether to carry article to the personnel between two risers 4 through detection mechanism to through interception mechanism cooperation operation, the legal operating personnel of identity that conveniently does not carry article and not drunk contacts construction machinery and carries out safe construction, and to other personnel's interception, avoids contacting construction machinery, and then guarantees the safe construction of job site, has improved the practicality of this equipment.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
