Detection device and method for accurate butt joint of ship chamber and lock head of ship lift

Abstract

The invention discloses a detection device and method for accurate butt joint of a ship chamber and a lock head of a ship lift. The device comprises a channel water diversion filtering unit, a channelwater depth reflecting unit and a ship chamber position detection unit. The channel water diversion filtering unit comprises a water diversion pipeline and a water containing cylinder. The water diversion pipeline is connected with the water containing cylinder, and a manual valve is arranged on the water diversion pipeline. The channel water depth reflecting unit comprises a connecting pipelineand a glass tube; and the water containing cylinder is connected with the glass tube through the connecting pipeline, and a magnetic floater is arranged in the glass tube. A signal transmission unit comprises a plurality of magnetic switches, induction surfaces of the magnetic switches are right opposite to the magnetic floaters, the magnetic switches are connected with the signal transmission unit, and the signal transmission unit is connected with a signal processing unit. According to the detection device and method for accurate butt joint of the ship chamber and the lock head of the ship lift, accurate detection of opposite positions of the ship chamber and the lock head can be achieved, an equipment failure rate is reduced, and butt joint efficiency of the ship chamber and the lock head is improved. The detection device has the advantages of a simple structure, a high adaptability, safety, reliability and the like.

Description

technical field [0001] The invention relates to a detection device and method for accurate docking of a ship lift cabin and a lock head, and relates to the technical field of ship lift cabin docking control. Background technique [0002] At present, the detection device for the accurate docking of the ship lift cabin and the lock head is composed of a photoelectric switch and a floating marker mirror system. The photoelectric switch has poor adaptability to bad weather and is easily disturbed by natural factors such as rain and snow; the floating sign mirror system is composed of floats, wire ropes, servo mechanisms, fixed pulleys, reflectors, counterweights, etc., and has a complex structure. Various types of faults such as wire rope broken strand jamming, servo motor damage, etc. often occur in the system, and the response of the servo mechanism lags behind the change of the water level. When the above-mentioned failures occur in the equipment, the ship lift cabin and the...

Problems solved by technology

The photoelectric switch has poor adaptability to bad weather and is easily disturbed by natural factors such as rain and snow; the floating sign mirror system is composed of floats, wire ropes, servo mechanisms, fixed pulleys, reflectors, counterweights, etc., and has a complex structure. Various types of faults such as wire rope broken strand jamming, servo motor damage, etc. often occur in the system, and the response of the servo mechanism lags behind the change of the water level

When the above-mentioned faults occur in the equipment, the ship lift cabin and the lock head cannot be accurately docked, which seriously affects the efficiency of ships passing the dam
