Description

Natural drop hydroelectric ship

technical field

The utility model relates to a hydroelectric generating device, in particular to a hydroelectric generating ship.

Background technique

Conventional hydropower stations need to build dams to raise the water level and head. The river water is stored in the reservoir area by the large embankment and becomes static water. Under the hydrostatic pressure of the high water level in the reservoir area, it flows to the breakthrough that can release the pressure, that is, the water diversion chamber, which becomes dynamic flowing water. Pressure pipes are installed in the dam to create a designed water drop for power generation. At present, there are very few domestic and foreign hydroelectric power plants with medium and high heads developed, and they may have an impact and damage on the ecological environment of rivers, lakes, and sea basins and the earth's surface crust.

Contents of the invention

The purpose of the utility model is to provide a natural drop hydropower ship with simple structure, low cost and easy installation.

The utility model is completed by the following technical solutions:

The utility model relates to a natural drop hydropower ship, which is composed of a flow gathering port, a diversion chamber, a drop pipe, a water turbine, a conical circular pipe, a draft pipe, a generator, a bearing seat, and a pontoon type hull. The water wheel mechanism, gearbox and generator are all installed in the hull. There is a converging port at the bow, the concentrating port is round or square, the diversion chamber is connected behind the diversion port, and the diversion chamber is connected to a backward-sloping drop pipe. The cross-section of the drop pipe can be circular or square, and the drop The pipe is connected with a conical circular pipe, and a tubular turbine is installed in the conical circular pipe, and a water inlet butterfly valve is provided between the tubular turbine and the drop pipe. The cross-section can be circular or square. A tailwater butterfly valve is provided at the rear of the draft tube, and the tubular turbine is connected to the generator and bearing seat in the hull. There are windlass, anchor piles, power control room and working room on the deck, and lightning rods, signal lamps and water tanks are installed on the top of the working room.

When the natural flow water enters the concentrating port and is pressurized, the density and speed of the water are significantly increased. After flowing into the water diversion chamber, due to the continuous extrusion of the water flow, it falls into the square drop pipe (pressure pipe), and its flow state becomes a rapid flow. When the inertial force and potential energy increase, the hydraulic turbine is driven to rotate and do work, and the energy is transmitted to the generator through the transmission shaft to generate electric energy. After the water flow done by the hydraulic turbine flows out of the cone pipe in a state of gradual flow and falls into the draft tube, the released uniform flow water mixes with the natural flow water and flows downstream together.

The utility model utilizes the floating box type hull as the carrier of the power station. It is constructed with cement or steel plates, and then a low-head tubular hydroelectric generator set is placed in it, and fixed in suitable and reasonable rivers, lakes, and seas to generate electricity. It can make full use of water resources and provide cheap electricity. The utility model also has the characteristics of simple structure, low cost, safety, reliability and high efficiency.
