Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Referring to attached drawing 1-4, the present invention provides a kind of hydroelectric installation, packet generating sets, hydroturbine rotor portion
Point and pressure spray part, hydroturbine rotor part includes runner 2-1 and one group of wheel blade 2-3, and wheel blade 2-3 number is with 3 ~ 4
Good, diametrically different hollow cylindrical, one group of wheel blade 2-3 heart coaxial with runner 2-1 are fixedly connected one group of wheel blade 2-3
In the ipsilateral of runner 2-1；Pressure spray part includes water inlet line 3-2 and one group of nozzle 3-3, nozzle 3-3 and water inlet line 3-2
It is connected, the whole arrangement in a ring of one group of nozzle 3-3 is equally spaced in the annular groove that one group of wheel blade 2-3 is formed,
Form wheel blade 2-3 and the opposite staggered cross structure of nozzle 3-3.Certainly, the annular groove quantity that wheel blade 2-3 is formed is not required and is sprayed
Quantity when mouth 3-3 annular arrangement is completely the same, can lack one, and as shown in Fig. 1, the annular that as wheel blade 2-3 is formed is recessed
Slot number one fewer than the quantity of nozzle 3-3 annular arrangement；The wheel blade at least one side is equipped with double wedge 2-3.2, preferably
All there is double wedge 2-3.2 on two sides, and to improve the utilization to water kinetic energy, the nozzle 3-3 includes water containing chamber 3-3.1 and ejection section 3-
3.2, the ejection section 3-3.2 are column type flat structure, the length direction of ejection section 3-3.2 and the axle center place of wheel blade 2-3
Straight line parallel, ejection section 3-3.2 are tilted by certain design angle, for example, water spraying direction be it is clockwise, when water flow is from water inlet
3-1 enters, and enters nozzle 3-3 by water inlet line 3-2, impacts ejection section 3-3.2 on double wedge 2-3.2 when spraying water, thus
