A variable track pulley type ultrasonic ship lock sill wear detection device

Abstract

The invention discloses a track-variable pulley vehicle type ultrasonic ship lock sill abrasion detection device and belongs to the technical field of measurement. The track-variable pulley vehicle type ultrasonic ship lock sill abrasion detection device comprises a starting point fixing block, an end point fixing block, a starting point fixing block pulley device, an end point fixing block pulley device, a starting point track groove, an end point track groove, a pulley, a pulley middle connecting shaft, a level gauge device, a pulley vehicle track groove, a suspending rod, an ultrasonic detection system, a probe and a control cabinet body, wherein a system power supply, a speed control system, a data acquisition system, a data analysis system and an output system are arranged in the control cabinet body. According to the track-variable pulley vehicle type ultrasonic ship lock sill abrasion detection device, the basic principle of ultrasonic ranging is adopted, and a pulley vehicle detection device body is composed of two pulleys. The invention further discloses a detection method of the detection device. According to the detection method of the detection device, the degree of abrasion of any point on the surface of a ship lock sill in the transverse direction or in the longitudinal direction can be detected, and the problem that the degree of underwater abrasion of the lock sill is difficult to detect is solved.

Description

technical field [0001] The invention relates to a variable track pulley type ultrasonic ship lock sill wear detection device, which can be widely used in various ship lock sill wear detection fields. Background technique [0002] The lock sill is a piece across the bottom of the lock entrance, for the gate to close against. In recent years, due to the lack of legal awareness of the crew, the drive of economic interests and the lax control of the source, the number of ships with drafts exceeding the limit has continued to increase. When a ship with an overdraft enters or exits the lock chamber, the bottom of the ship will have a strong abrasion effect on the lock sill, and some lock sills have even been ground flat, seriously affecting the safety and maintenance of the lock. [0003] The detection and evaluation of the sill of the ship lock is of great significance to the safety of the ship lock. However, because the sill is located underwater and the turbidity of the water ...

Problems solved by technology

However, when a ship with an overdraft enters or exits the lock chamber, the bottom of the ship will have a strong abrasion effect on the sill, and some sills have even been ground flat, which seriously affects the safety and maintenance of the lock.

[0003]The detection and evaluation of the lock sill is of great significance to the safety of the ship lock. Due to the complexity of the water quality and flow conditions in the approach channel, the underwater cameras are often unable to perform the task of underwater sills

In the previous detection methods, the method of artificially diving into the bottom of the water is mostly used, but this method is difficult to operate and dangerous, and it is impossible to accurately determine the position and size of obstacles
