Description

Strong tracking float suitable for prototype observation of flow velocity distribution in the gate area of navigation hub

technical field

The invention relates to the field of water body monitoring, in particular to a strong tracking float suitable for prototype observation of the flow velocity distribution in the gate area of a navigation hub.

Background technique

After the construction of water conservancy, hydropower and avionics projects in natural rivers, in order to ensure navigation, navigation structures such as ship locks or ship lifts are often set up. At the entrance and exit of navigable buildings, that is, the entrance area where the approach channel on the upper and lower reaches of the lock is connected with the river (or canal), the water flow in this area is generally composed of two parts: the oblique water flow and the return flow, which is the way for ships passing through the lock to enter and exit the approach channel. throat. It is located at the junction of the flowing water of the river and the still water of the approach channel. Due to the particularity of this arrangement, the mouth gate area is affected by the boundary conditions such as the discharge structures and the navigation diversion structures in the hub, and the upstream mouth gate is the river channel. The section narrows, and the channel section for the downstream gate is widened. Therefore, when the water flow in the channel is in the condition of shrinking (to the upstream) and expanding (to the downstream), the water flow is bent and deformed, resulting in a flow velocity gradient and an oblique water flow. Due to the action of the oblique water flow, backflow and separation-type small vortices are generated. The cross-flow and backflow cause the sailing ship to drift and twist, and in severe cases, it will be out of control, and even marine accidents will occur, affecting the navigation. Therefore, it is of practical significance to understand the mechanism that affects the water flow conditions in the mouth area, the relative position of the ship lock in the hub, and various measures to improve the water flow conditions in the mouth area, and to summarize experience.
