Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit liquid detection, and particularly relates to a liquid detection device. Background Art

[0002] Rail transit refers to a type of transportation means or transportation system in which operating vehicles need to run on specific tracks. Common rail transits include traditional railways (ordinary railways, intercity railways, and suburban railways), subways, light rails, and tramways. In addition, there are new types of rail transits such as maglev track systems and monorail systems. When rail transit conducts security checks, passengers usually place their luggage on the security inspection machine. The checked luggage and items are sent into the crawler-type channel by means of a conveyor belt, and the items to be inspected are irradiated with a small dose of X-rays, and the simulated images of the items in the luggage bag are presented on the display screen. The liquids carried need to be manually detected by a liquid detection device to determine whether they can be carried. Generally, the liquid detection device is inside the luggage security inspection and sorting device, and passengers need to find an open space to take out the liquid for detection after passing through the security check; or passengers are already holding the liquid, but they need to pass through the security gate by themselves and then give the liquid to the security inspector for detection, which prolongs the security check time and is extremely easy to cause congestion at stations with a large flow of people. Content of the Utility Model

[0003] Aiming at the problems raised in the above background art, the purpose of the present utility model is to provide a liquid detection device.

[0004] To achieve the above technical purpose, the technical solution adopted by the present utility model is as follows:

[0005] A liquid detection device includes a bottom support. One side of the bottom of the bottom support is provided with an opening. An outlet guiding sleeve is installed above the opening inside the bottom support. A collection box is installed on the other side inside the bottom support. A detection seat is installed on the top of the bottom support. A detection through groove is provided at the center of the detection seat. A flat plate is provided at the bottom of the detection through groove. Rotating rods are installed on both sides of the flat plate. Bearing seats are installed on the outer sides of the rotating rods. The bearing seats are fixedly installed at the bottom of the detection seat. One of the rotating rods is also connected to a driving motor. A liquid scanner is also installed on one side inside the detection seat. A support frame is installed at the outer bottom of the bottom support. The support frame is connected to a conveyor belt. The conveyor belt is arranged directly below the opening.

[0006] Further defined, the outlet guiding sleeve and the collection box have the same size and structure, and are both installed in the bottom support by screwing. Such a structural design facilitates subsequent disassembly, assembly, and maintenance.

[0007] Further defined, a step groove matching the top of the bottom support is provided at the bottom of the detection seat. Such a structural design facilitates the connection between the detection seat and the bottom support.

[0008] Further defined, positioning grooves are provided on both sides of the bottom of the detection base. A positioning spring is installed in the positioning groove. The free end of the positioning spring is connected to a limit seat. A positioning bead is slidably installed in the limit seat. A through hole is also provided on the side wall of the positioning groove. The limit seat is slidably arranged in the through hole. The bottom tray is provided with a positioning hole corresponding to the positioning bead. One side of the positioning bead is arranged in the positioning hole. Such a structural design achieves the connection and positioning effect between the detection base and the bottom tray.

[0009] Further defined, a detachable cover plate is also installed on the outside of the liquid scanner on the detection base. Such a structural design achieves a sealing and protective effect on the liquid scanner.

[0010] The beneficial effects of the present utility model are as follows: The present utility model scans and detects the liquid in the container through the liquid scanner. If it is a dangerous liquid, the driving motor drives the rotating rod to rotate in the bearing seat and at the same time drives the flat plate to tilt to the right, so that the container slides along the tilted flat plate and enters the collection box for centralized collection. If it is not a dangerous liquid, the driving motor drives the rotating rod to rotate in the bearing seat and at the same time drives the flat plate to tilt to the left, so that the container slides along the tilted flat plate and is guided by the discharge guiding sleeve and then falls onto the conveyor belt. The conveyor belt conveys the normal liquid out. In this way, when the passenger picks up the luggage bag, the liquid can be taken away at the same time, reducing the security inspection time and preventing congestion at the station.
