Water energy storage and distribution device, water energy storage equipment and water energy storage control method thereof

Abstract

The invention discloses a water energy storage and distribution device, water energy storage equipment and a water energy storage control method thereof. The water energy storage and distribution device comprises a water distribution pipe, a water distribution deceleration groove suspended below a port of the water distribution pipe and facing the port from the open side, a flow speed control plate located on the open side of the water distribution deceleration groove and arranged at the end of the water distribution pipe in a sleeving mode, and a flow deflector connected to the periphery of the open side of the water distribution deceleration groove; the flow speed control plate can slide back and forth in the axial direction of the end part of the water distribution pipe; and an annularwater passing opening for water to enter and exit from the water distribution deceleration groove is formed between the periphery of the flow speed control plate and the open side of the water distribution deceleration groove. The water energy storage and distribution device is used in an energy storage water tank, control over the flow speed of water flow is achieved, the problem that turbulent flow occurs in the energy storage water tank due to the fact that the flow speed cannot be controlled is avoided, the flow speed of water flowing into or out of the energy storage water tank through apipeline can be effectively reduced, the height of a thermocline of the energy storage water tank is reduced, and the energy storage efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water energy storage, in particular to a water energy storage distribution device, water energy storage equipment and a water energy storage control method thereof. Background technique [0002] In the existing field of water energy storage technology, its water distribution technology is the key to ensuring the efficiency of energy storage and discharge. The common forms of water distribution and piping in the water energy storage system adopted by energy storage manufacturers in the existing market mainly include: octagonal cloth Water dispenser, radial disc water distributor, linear water distributor. For the specific forms of water distribution involved, each company has developed products with independent intellectual property rights based on its own technology. Most of them adopt the form of water distribution pipes to open holes to form line water distribution, and some use the form of point water ...

AI Technical Summary

Problems solved by technology

Although many energy storage cases have been implemented in the domestic market, the success of the project is sometimes closely related to the manufacturer and individual technical personnel and there are certain uncontrollable conditions, resulting in uneven situations. The key is the water flow into the project. Or when flowing out of the energy storage tank (tank), the flow rate control is out of control, which is easy to cause disturbance to the energy storage and discharge piston movement of the cold storage tank (tank), especially the key control parameters closely related to water distribution. The Froude number (Fr) and If the Reynolds number (Re) is not well controlled when storing and discharging energy, it will cause a large thermoclinic layer and reduce the available cold heat, thereby reducing the efficiency of cold storage and discharging, and the expected effect cannot be achieved
