Abstract

The utility model relates to a generating unit, in particular to a vessel-anchored hydroelectric generating unit and solves the problems that the existing hydroelectric generating unit is high in cost, large in cycle length, destructive to ecological environment and the like. The vessel-anchored hydroelectric generating unit comprises an anchor cable anchored to both sides of a river, and a pontoon. A water tank, a generator and a gearbox are disposed on the pontoon, wherein the generator and the gearbox are disposed at the top of the water tank. The top of one end of the water tank, on the upstream side, is provided with a water inlet. The bottom of the other end of the water tank, on the downstream side, is provided with a water outlet. A horizontal water pipe and a slanting water pipe connected end to end are disposed between the water inlet and the water outlet. An impeller and an impeller shaft are disposed in the slanting water pipe. The impeller shaft extends out of the water tank, and the tail end of the impeller shaft is connected with an output shaft for the generator and the gearbox through a thrust bearing. The vessel-anchored hydroelectric generating unit is low in investment, responds fast, is friendly to ecological environment, is suitable for various rivers, has low requirement on river potential, enables water power resources to be fully utilized, and is simple in structure, easy to implement and effective to use.

Description

Anchor ship hydroelectric installation

Technical field

The utility model relates to a kind of electricity generating device, is specially a kind of anchor ship hydroelectric installation.

Background technique

The energy is human lives and economic development breath of life, along with the development of economic society, the consumption of the energy will get more and more, and row's carbon is also more and more, greenhouse effect also can faster development, so clean energy resource has been exactly the top-priority thing of we Earthian.

At present, utilizing waterpower to generate electricity nearly all is to adopt building to block dykes and dams to flood, and it is lower that water is rushed down from a high position, leans on the vane rotary of the impact force pushing generator of water, thereby reach the purpose of generating.The advantage of prior art is to build powerful power station, but the addressing that its shortcoming one is the power station is subjected to the restriction of landform, the place that must have sufficient natural head, particularly in the downstream of rivers, physical features is more smooth, the flow velocity of water is lower, can't Store water, and this part energy can not well utilize so far; The 2nd, it is expensive large to build the dam, and the cycle is long; The 3rd, Store water along with the raising of water level, is destroyed the original ecology in dam district, causes the natural disasteies such as landslide, and many troubles such as immigrant's resettlement etc.

Summary of the invention

The utility model provides a kind of anchor ship hydroelectric installation in order to solve problems such as having the hydroelectric installation addressing is subjected to landform to restrict, cost greatly, the cycle is long, destruction ecotope now.

The utility model is to adopt following technological scheme to realize: anchor ship hydroelectric installation, comprise the anchor cable that is anchored at the two sides, river, the pontoon that is connected with anchor cable, pontoon is provided with water tank and is positioned at the generator of tank top, gearbox, on water tank one end face and a side roof part that is positioned at upper river have water intake, on the water tank other end and a side bottom that is positioned at lower reaches of river have water outlet, be provided with horizontal segment overflow pipe and tilting section overflow pipe that head and the tail connect between water intake and the water outlet; Impeller and impeller shaft are installed in the tilting section overflow pipe, and impeller shaft stretches out outside the water tank, and end is connected by the output shaft of thrust-bearing with generator, gearbox.

The water tank one end both sides that are positioned at upper river are respectively equipped with telescopic flow-stopping plate, and two telescopic flow-stopping plates are open type angle structure, and this structural design can further increase speed and the flow of flowing water.

Adopt structural design of the present utility model, after being fixed on pontoon in the river that the water flows gently, current are entered in the water tank by water intake, and pass through successively horizontal segment overflow pipe, tilting overflow pipe, are finally discharged by water outlet, in this process, current promote to be arranged in the vane rotary of tilting overflow pipe, and impeller shaft rotates through the output shaft that thrust-bearing drives gearbox, then drive the generator amature rotation, the kinetic energy of water in the river is passed to generator, thereby realize hydroelectric purpose.

Compared with prior art, since do not need to build the retaining dam, little investment, instant effect, can not destroy ecotope yet, because it can be made into single ship unit group, single ship multicomputer or many ships multicomputer according to the flexible in size layout of area and the flow velocity of water, this device is suitable in the various rivers, potential energy to the river requires less, can take full advantage of waterpower resourses, simple in structure, easy enforcement, using effect is good.
