Description

具有发电功能的双水轮机式分散输水系统Double-turbine decentralized water delivery system with power generation function

技术领域 technical field

本发明涉及一种具有发电功能的双水轮机式分散输水系统，具体地说是在传统分散式输水系统的基础上，进行必要的改进，通过新安置的两台水轮机并配合不同的阀门启闭方案，使得船闸在正常运行过程中兼顾发电功能，从而在保障闸室具有良好的船舶停泊条件的同时，充分利用了上下游较大水位差中所蕴含的能量。 The present invention relates to a distributed water delivery system with double water turbines with the function of generating electricity. Specifically, on the basis of the traditional distributed water delivery system, the necessary improvements are made, and the two newly installed water turbines are used together with different valves to start the system. The closure scheme allows the lock to take into account the power generation function during normal operation, so that while ensuring good berthing conditions for ships in the lock chamber, it makes full use of the energy contained in the large water level difference between the upstream and downstream.

背景技术 Background technique

在船舶过闸的过程中，上游大量水体经船闸输水廊道直接排泄至下游，导致这部分水体所蕴藏的能量处于流失状态。考虑到巨大的船舶过闸日流量和年流量，这部分水体所蕴藏的能量则相当可观。如果对其加以合理开发利用，使其转化为对生产生活有益的电能，在传统能源日益枯竭而需要大力发展新能源的今天，具有重大的战略意义。 During the process of the ship passing the lock, a large amount of water from the upstream is directly discharged to the downstream through the water delivery corridor of the ship lock, resulting in the loss of energy contained in this part of the water. Considering the huge daily flow and annual flow of ships passing through the lock, the energy contained in this part of the water body is quite considerable. If it is rationally developed and utilized to convert it into electric energy that is beneficial to production and life, it will be of great strategic significance today when traditional energy sources are increasingly exhausted and new energy sources need to be vigorously developed.

与此同时，随着高水头、大型船闸在实际中的运用越来越广泛，分散输水系统以其能够适应较高的水头、具有较高的输水效率和良好的船舶停泊条件等优点，在实际的工程中得到越来越多的应用。 At the same time, as high water heads and large ship locks are more and more widely used in practice, the decentralized water delivery system has the advantages of adapting to higher water heads, higher water delivery efficiency and good ship berthing conditions. It has been applied more and more in practical engineering.

由于分散式输水系统适用于高水头船闸，水头越高就意味着上述的这种水力资源越丰富，就越具有开发利用的价值，若不加以合理地开发与利用，对于这种水力资源来说是一种极大的浪费。 Since the decentralized water delivery system is suitable for high-head ship locks, the higher the water head, the richer the above-mentioned hydraulic resources, and the more valuable they are for development and utilization. If they are not developed and utilized reasonably, the water resources will be Said to be a great waste.
