Stop-log type gate water outlet tank for river work model

Abstract

The invention discloses a stop-log type gate water outlet tank for a river work model. The stop-log type gate water outlet tank comprises a tank body, wherein the top of the tank body is opened. A water outlet pipe is arranged at one side of the tank body. One end of the water outlet pipe is fixed to the tank body and communicates with the interior of the tank body, and the other end of the water outlet pipe penetrates a model basin and extends to a drainage system. Multiple gates are arranged at one side of the tank body and are in sequential sealed head-to-tail connection and arrangement in the longitudinal direction. By means of the stop-log type gate water outlet tank, panels the same as those of the model basin can be used; materials are convenient to select; the production process is also the same as that of the model basin; the water level of the water outlet tank can be controlled in real time, precisely, easily and conveniently; latex tubes are used, and by means of the effect of the gates and the hydrostatic pressure, good sealing performance can be achieved; by means of a water release control valve, fine adjustment of the water level can be achieved; by means of triangular plates for support, the entire stress of the gates is increased; and meanwhile, energy dissipation can be conducted on water outlet, water can flow out steadily, and damage of impact to a pipeline is reduced; and by means of the stop-log type gate water outlet tank, the effect that the water level of the water outlet tank for a river work model test is adjusted stably can be well achieved.

Description

technical field [0001] The invention relates to a water outlet box for a stacked beam gate of a river engineering model, and belongs to the technical field of river engineering model tests. Background technique [0002] Adjusting the water level of the outlet tank is one of the key technologies for river engineering model tests. Most of the model tests roughen the model by controlling the water level of the outlet tank, and measure the upstream water level changes by adjusting the water level of the outlet tank during the test. The adjustment of the water level of the water tank is better controlled by the stacked beam gate. Other ways of adjusting the water level of the outlet tank include outlet pipe gate control and electronic control gate etc. at present. The outlet pipe gate and electronic control gate control have high requirements on the material of the outlet pipe, the manufacturing cost is high, the design of the outlet pipe gate control is complicated, it is diffi...

AI Technical Summary

Problems solved by technology

The outlet pipe gate and electronic control gate control have high requirements on the material of the outlet pipe, the manufacturing cost is high, the design of the outlet pipe gate control is complicated, it is difficult to operate underwater, it is difficult to find out whether there is damage such as water leakage, and the water surface is disturbed during operation. , it is difficult to balance the water surface of the water tank, it is difficult to control the electronic gate stably, the electronic data changes instantaneously, and the water level may fluctuate, which will take more test time
