Description

Water level measuring device of inland river ship lock

Technical Field

The utility model relates to a water level measuring device technical field specifically is a water level measuring device of inland river ship lock.

Background

Ship lock, refers to a kind of "navigation building". In natural rivers, because of the regulation of flow, canalization navigation and the restriction of topographic conditions and water surface gradient on the canal, a step-shaped vertical section is required to form a concentrated water surface drop. The vessel must be moved directly through the drop by means of a special navigable building. Modern navigable buildings are most commonly used in ship locks. It is a box-shaped structure, consisting of upstream and downstream navigation channels and upstream and downstream gate head connecting chambers. The lock chamber is a box-shaped chamber for parking ships (or fleets), and the water level in the lock chamber is adjusted by means of water filling or draining in the lock chamber, so that the ships vertically ascend and descend between upstream and downstream water levels, and the water level fall of a concentrated channel is passed. When boats and ships went upstream by the low reaches, indoor water level falls to flushing with the low reaches water level, then opens the gate of low reaches lock head, and the lock room is gone into to the ship, closes the gate, and the watering is waited that the water level rises to flush the back with the upper reaches water level, opens the lock head gate of upper reaches, and the ship can go out the floodgate and navigate to the upper reaches through upper reaches approach channel. When the ship runs from upstream to downstream, the brake-passing operation procedure is opposite to the brake-passing operation procedure.

One of the ship lock opening conditions is that the water level reaches the certain degree, consequently need measure the ship lock water level, mainly carry out liquid level indication through level sensor or buoy cooperation liquid level scale at present, but above-mentioned two kinds of modes are when carrying out actual water level measurement, receive the influence of surface of water wave easily, lead to level sensor's detection data unstable, perhaps reciprocating motion about the buoy, lead to unable accurate instruction liquid level scale, such measurement mode leads to influencing the liquid level to a certain extent and detects.
