Ship lock floating access door device and automatic sinking and floating control method

Abstract

The invention discloses a ship lock floating access door device and an automatic sinking and floating control method. The device is provided with a central water cabin, side water cabins and adjustingwater cabins, all the water cabins are communicated through pipelines below the cabins, the central water cabin is used as a main water supply cabin of other water cabins, the floating and sinking and sinking depth of the device can be controlled by adjusting the water level in the adjusting water cabins through a control device, the posture of the device is sensed through a posture sensing device, and the flow and the speed entering each adjusting water cabin are controlled by adjusting the opening and closing degree of each electric adjusting valve. During drainage, a drainage pump is usedfor draining water to enable the device to float, the whole floating and sinking process and the posture control are automatically completed through the control device, the posture and the floating and sinking speed of the device can be accurately controlled, the situation that the device overturns due to inaccurate manual adjustment is avoided, and the safety and the automation degree are greatlyimproved.

Description

technical field [0001] The invention relates to the field of ship lock maintenance, in particular to a ship lock floating maintenance door device and an automatic sinking and floating control method. Background technique [0002] When large-scale navigable ship locks are suspended for inspection and maintenance, they will be shut down and closed, and the accumulated water in the lock room will be drained before construction operations. Usually, due to water leakage of the upstream and downstream maintenance water retaining facilities during the operation, the upstream and downstream storage sections and transportation The continuous flow of water in the water corridor makes it difficult to repair the working gate of the ship lock and the damaged repair of the hydraulic structure of the corridor. It is necessary to carry out water retention and drainage to form a local dry area for maintenance. The construction of traditional earth-rock cofferdams consumes a lot of manpower a...

[0002] When large-scale navigable ship locks are suspended for inspection and maintenance, they will be shut down and closed, and the accumulated water in the lock room will be drained before construction operations. Usually, due to water leakage of the upstream and downstream maintenance water retaining facilities during the operation, the upstream and downstream storage sections and transportation The continuous flow of water in the water corridor makes it difficult to repair the working gate of the ship lock and the damaged repair of the hydraulic structure of the corridor. It is necessary to carry out water retention and drainage to form a local dry area for maintenance

The construction of traditional earth-rock cofferdams consumes a lot of manpower and time, the construction environment on site is poor, and more or less pollutes the water body, which does not meet the requirements of rapid maintenance and environmental protection construction of ship locks

[0003] The ship lock floating maintenance door is a water retaining facility, mainly used to isolate the lock chamber from the water body of the downstream approach channel, so as to facilitate the drainage of the lock chamber, and provide a working surface for the implementation of the ship lock chamber maintenance project, which is suitable for the ship lock chamber maintenance , but the current floating inspection door cabins are rough and only set up sinking and floating cabins, which is not conducive to the attitude adjustment of the inspection door, and the valves are switched manually. A slight improper operation will cause the floating inspection door device to overturn. Precise control of the attitude and ups and downs of the lock's floating access door can greatly improve the operability of the floating access door, making it easy to use, safe and feasible
