Background technique

All pay much attention to utilization both at home and abroad to water resources; As many water power plants and water-control project have been built in succession; But generally the height of water is required more than 40 meters, and some water power plants, dam Pentium and the high-velocity flow that goes out can not get utilizing preferably, and the leeway that these water resourcess still much can be utilized in addition again; And the reason that these water resourcess can not get effectively utilizing is that present hydraulic turbine structure still haves much room for improvement, and this improvement is imperative.

Summary of the invention

To above-mentioned situation; For overcoming the defective of existing technology; The purpose of the utility model just provides a kind of the flat towards the water resistance type hydraulic turbine generator of anti-swelling pipeline that have, and can effectively solve some water power plants, dam Pentium and problem that the high-velocity flow that goes out can not get utilizing preferably.

The technological scheme of its solution is, comprises pipeline, impeller and fixed base, and laterally an end of aqueduct leads to the bottom of the eminence water surface; The other end of horizontal aqueduct leads to fixed base; Vertically in the aqueduct axis is housed, fixed base is equipped with in the bottom of axis and pipe tunnel on the lower water surface, under water axis below the fixed base, impeller is housed; Fixed base is equipped with in the underpart of axis in the below of impeller, and axis is connected with electricity generating device above fixed base.

The utility model novel structure is unique, advantages of simple, and cost is low, and is easy for installation, low to the water-head requirement, can utilize water resources fully, and good economic and social benefit is arranged.

Description of drawings

Fig. 1 is the structural drawing of the utility model.

Embodiment

Explain further details below in conjunction with the embodiment of accompanying drawing to the utility model.

Provide by Fig. 1; A kind of have the flat towards the water resistance type hydraulic turbine generator of anti-swelling pipeline, comprises pipeline, impeller and fixed base, and laterally the end of aqueduct 1a leads to the bottom of the eminence water surface 2; The other end of horizontal aqueduct 1a leads to fixed base 3a; Vertically in the aqueduct 1b axis 4 is housed, fixed base 3b is equipped with in the bottom of axis 4 and pipe tunnel 1b on the lower water surface 6, under water axis 4 below the fixed base 3b, impeller is housed; Fixed base 3c is equipped with in the underpart of axis 4 in the below of impeller, and axis 4 is connected with electricity generating device 11 above fixed base 3a.

In order to guarantee using effect, described horizontal aqueduct 1a and vertical aqueduct 1b are connected to form aqueduct.

Anti-swelling pipeline is housed on the described horizontal aqueduct 1a; Anti-swelling pipeline is by being connected to form for two sections with the laterally anti-swelling pipeline 5b parallel with horizontal aqueduct 1a with the vertical vertically anti-swelling pipeline 5a of horizontal aqueduct 1a; Vertically anti-swelling pipeline 5a one end communicates with horizontal aqueduct 1a, and the other end communicates with laterally anti-swelling pipeline 5b.

Axis 4 in described vertical aqueduct 1b is separately fixed on

fixed base

3a, 3b and the fixed base 3c through bearing support and bearing, and vertically aqueduct 1b is for fixing, and axis 4 can rotate.

Described impeller comprises some groups of sub-propellers 8 and a main impeller 9, is contained in successively on the axis 4 up and down.。

Described main impeller 9 be circle shape box, axis 4 is positioned at the central authorities of main impeller and links to each other the water intake that the top of main impeller 9 has opening to make progress with main impeller 9; Identical with the bore of vertical aqueduct 1b, and dock with vertical aqueduct 1b, on the edge of main impeller 9, be provided with water outlet; The opening direction of water outlet is identical with the tangent direction at the edge of main impeller 9, is communicated with through water channel between water intake and the water outlet, and water channel is 2～10; Be from top to bottom one section helical arc from the inside to the outside.

Described sub-propeller 8 is that the baffle plate of around main impeller 9 water outlets, setting up ring-type constitutes.

The use condition of the utility model is during use, two kinds of methods to be arranged; The water that the first is discharged the water power plant utilizes again; Can the utility model be installed on the water orifice place in water power plant, connect, electricity generating device is installed on the place of barrage below away from dam through pipeline; The water power plant is neither influenced the generating of normal main water turbine, can the current of ejection be utilized again again; It two is self-built barrages, and the aqueduct of the utility model is led to the bottom of barrage, and electricity generating device is installed on the barrage below or away from the place on dam, directly utilizes the water of barrage to generate electricity.Water gets into vertical aqueduct 1b through horizontal aqueduct 1a, and anti-swelling pipeline plays the effect that prevents that swelling is stifled, and water finally gets into the water intake of sub-propeller 8; Water outlet through sub-propeller 8 gets into the water intake of main impeller 9 again, and water passes through water channel in the water outlet flow process by water intake in sub-propeller and main impeller, and water is when water outlet flows out; According to momentum conservation and active force reaction force principle, the water of ejection produces a kind of reaction force under the effect that receives smooth water resistance; Under the effect of reaction force; Promoted the rotation that sub-propeller and main impeller reach fixing axis on it, axis finally drives the rotation of electricity generating device, thereby realizes generating.
