Water supply device with different-temperature water layering flowing simulation function

Abstract

The invention relates to a water supply device with a different-temperature water layered flowing simulation function. The water supply device comprises a water supply front pool, and the water supply front pool is provided with an overflow weir and a water flow actuator. The water flow actuator is connected with a layered partition plate box and comprises two flow guide plates and a vertical water spraying pipe and a water inlet grating. The water spraying pipe is provided with a plurality of water-permeable holes; the water inlet grating is composed of a plurality of plate faces and strip plates, wherein the plate faces are vertically arranged downwards from the water surface side by side, and the strip plates are arranged in the direction perpendicular to the water flow direction; horizontal partition plates are arranged in the layered partition plate box and are evenly distributed in the vertical direction. Due to the adoption of the water flow actuator formed by the water spraying pipe and the flow guide plates, water can flow smoothly because the water can flow out of the multiple vertical holes of the water spraying pipe, and the influence on water in a heating region is small. The water flow actuator can effectively push the water to flow downstream, and the two sides of water around the water-permeable holes are prevented from turning and rolling to affect downstream flowing of heated water. The water supply device effectively solves the problems that the work amount of a stable-layering non-mixing water adding device is large and dynamic adjustability is poor in the prior art.

Description

technical field [0001] The invention relates to a water supply device for simulating the stratified flow of water temperature, which is a water supply device for an environmental protection ecological hydraulic experiment system, and a simulation experiment system for water flow from shallow to deep in reservoirs and deep-water rivers and water temperature changes water supply unit. Background technique [0002] Using the water temperature layered physical model test method is a widely used and very effective technical means to study the problem of layered water intake. The existing physical experiment of water temperature stratification adopts the method of slowly layering and injecting water of different temperatures into the water body in the test pool. Due to the difference in the density of the water body, the cold water submerges and the hot water floats up, finally forming the condition of water temperature stratification. However, in the actual operation process, it...

Problems solved by technology

Although this patent solves the problem of water temperature mixing to a certain extent, when there are many layers of water temperature, the engineering quantity is large and the dynamic adjustment is poor.

In addition, although the above method can form the vertical distribution of water temperature in the initial stage, once the water intake starts and the flow state is formed in the reservoir, the vertical distribution of water temperature will change again, and at the same time, the water body in the reservoir will gradually decrease.

During the simulation process, the water temperature-flow field cannot reach a stable state, and the duration is relatively short. Therefore, it is still impossible to simulate the continuous stratified flow process caused by water intake at the water inlet in large-scale water temperature stratified reservoirs, that is, it is impossible to simulate the dynamic flow field for a long time Stable stratified temperature field variation in
