Bidirectional water supply and inlet tank for river model test

Abstract

The invention discloses a bidirectional water supply and inlet tank for a river model test. The bidirectional water supply and inlet tank comprises a water tank body. The water tank body straddles andis positioned in the width direction of a simulated river channel. Water in the water tank body can simultaneously flow to the two sides of the simulated river channel. Multiple water outlet holes are uniformly formed in a set of opposite side plates, facing the simulated river channel, of the water tank body. Water inlet holes are formed in side plates, positioned on banks on the two sides of the simulated river channel, of the water tank body. Water inlet pipes are fixedly connected into the water inlet holes. The water inlet pipes communicate with the interior of the water tank body. The water is delivered into the water tank body from the water inlet pipes, flows out from the water outlet holes, enters the simulated river channel and simulates the water flow in the river channel. By the adoption of the bidirectional water supply and inlet tank for the river model test, the control test effect is particularly remarkable for the same model, simultaneous water supply and simultaneouswater cut off can be realized, meanwhile data are acquired, the obvious control value is provided, the interference of other relevant factors is eliminated, and the test result is more convincing.

Description

technical field [0001] The invention relates to a two-way water supply inlet box for a river engineering model test, and belongs to the technical field of river engineering model tests. Background technique [0002] The water supply of the water tank is one of the key technologies of the river engineering model test. Any river engineering model test needs water supply to carry out relevant tests. Therefore, the water tank for the model test is directly related to whether the river engineering model simulation can be carried out normally. [0003] During the river engineering model test, if the pipeline is directly connected to the model river bed, it will seriously interfere with the actual water level and flow velocity of the river and other hydrodynamic parameters, and it will also cause scour to the river, which will directly lead to the failure of the model test. In a normal model test, the upstream will maintain a slow overflow or a uniform flow close to no flow velocit...

Problems solved by technology

Especially for multiple tests at the same time, higher requirements will be placed on the water volume of the reservoir. If the water volume in the reservoir is small, only one model can be tested. If the water volume in the reservoir is large, it will place greater requirements on the overall structure of the laboratory. Increasing the capacity of the reservoir, increasing the power of the water pump, increasing the diameter of the pipeline, etc., will cause a series of structural modifications, which will greatly increase the cost of the test

However, most of the laboratories were built in the last century, and their age is relatively long, so it is difficult to shape and transform the structure.

The progress of the river engineering model test will be slow due to the difficulty of water supply for the test
