Abstract

A high-rise tap water fluid power generation system is a system which utilizes high pressure tap water from a high-rise water supply pipe to impact impeller vanes to drive a generator to generate electricity. The high-rise tap water fluid power generation system is characterized in that the vanes of a cylindrical water turbine are installed in a tap water pipe, high-rise high pressure tap water is utilized to impact the impeller to rotate to drive a fluid generator to generate electricity and directly transfer generated electricity to user units or store the electricity in an energy storage device. The cylindrical water turbine is composed of a sealing cover, a bearing, a water sealing device, an impact chamber, a cylindrical casing, a spindle and the impeller. The impeller is located in the impact chamber, and the spindle penetrates through the cylindrical casing through the bearing. The cylindrical casing is composed of two lateral planes and a circumferential cylindrical face, a water inlet and a water outlet are arranged on the circumferential cylindrical face of the cylindrical casing, and openings are all located on one side of the axis of the cylindrical casing. Two ends or one end of the spindle stretches out of the cylindrical casing to be connected with the fluid generator through a coupler. The integral structure design of the cylindrical water turbine facilitates installation arrangement of the power generation system.

Description

High building tap water fluid power-generation system

Technical field:

The invention belongs to field of energy-saving technology, particularly utilize high building tap water fluid power-generation.

Background technique:

Along with the high speed development of China's economic and the quickening of urbanization process, ever-increasing urban population and Limited Land resource contradiction increasingly sharpen.In the face of this problem, under the condition of land limited, fully extend the idea of utilizing space resources and obtain the approval of government and adopt.So high building has been brought into play great function in solving ever-increasing urban population and this contradiction of limited urban land resource.But along with floor is more and more higher, the mode of high-order water tower water-feeding has obtained effective utilization and has obtained significant practical effect.With pump, water being delivered in the water tower of roof under the condition of not considering energy loss, is the gravitational potential energy with electric energy conversion Cheng Shui.So, in the situation that do not disturb only normal water supply, from the process that roof flows down, these energy can utilize fully and not affect normal water supply at water.

Through consulting as can be known, present high building running water generating device is mainly axial flow, be that current are parallel with rotatingshaft, this kind device comes with some shortcomings: (1) tap water pressure does not reach when driving the axial flow blade rotation, generator does not generate electricity, this has just increased the narrow limitation of this electricity generating device, has seriously reduced high building water use efficiency from the beginning.(2) owing to there being larger gap between axial blade and tube wall, have leakage phenomenon between axial blade thereby make, the tap water energy can not take full advantage of.(3) blade and axle are arranged on pipeline center, cross-section of pipeline is amassed reduce, and affect the tap water flow.(4) the blade main shaft on the pipe interior center line, can only can stretch out pipeline and be connected with generator in the elbow, or takes other complicated transmission ways, with main shaft power output, the mounting point of having limited generator.

Summary of the invention:

In order to overcome present the problems referred to above, the present invention designs a kind of gravity type fluid generator that adopts the global design of cylindricality water turbine and fluid generator composite structure form, be convenient to be arranged on and adopt eight or ten or 12 rectangular paddle on water supply pipe, symmetry is arranged on rotary main shaft, individual blade length and width are slightly larger than the water supply pipe diameter, blade outer surface and cylindrical outer cover internal surface all need be done surface treatment, guarantee its gap all in 0.5mm, reduce tap water as far as possible and leak.Current are vertical with rotatingshaft, stretch out outside cylindrical outer cover bi-side the main shaft one or both ends can connect fluid generator, fluid generator can be arranged on any position of pipeline, and this device can take full advantage of the energy of roof tap water, has solved the deficiency of axial flow running water generating device.

Advantage of the present invention: the potential energy of (1) tap water and kinetic energy can drives impeller rotate, drive fluid generator generating: between (2) impeller blade and cylindrical outer cover internal surface, very little gap is only arranged, have hardly leakage phenomenon, the tap water energy is fully used; (3) single impeller blade area is long-pending greater than cross-section of pipeline, does not affect the tap water flow; (4) cylindricality impeller global design, install any position of being convenient on water supply pipe, also can on a pipeline, a plurality of electricity generating devices be installed simultaneously, utilizes to greatest extent the tap water energy; (5) the cylindricality hydraulic turbine structure is simple, and strong adaptability also can be applicable to high building drainage pipeline and urban sewage discharge pipeline, has greatly improved the urban water system capacity usage ratio.
