Abstract

The purpose of the present invention is to provide a full-pressure hydroturbine, and the technical problem which needs to be resolved is to increase the water energy conversion rate of the hydroturbine. The following technical scheme is adopted: the full-pressure hydroturbine comprises an enclosure, a water inlet, a main shaft and a water wheel; wherein, the water inlet is arranged on one side of the enclosure; the water wheel is arranged on the main shaft; a big rotating wheel, which is arranged on the outer edge of the water wheel, partitions the water wheel into an upper chamber and a lower chamber; in the upper and the lower chambers, the middle part of the big rotating wheel is respectively connected with equantly arranged movable blades through blade shafts; and a blade-positioning shaft is arranged between each two movable blades. Compared with the prior art, because the movable blades are utilized to form a pressure cavity to push the rotating wheel to rotate, the load speed, which fluid dynamic energy encounters, is eliminated, the fluid refraction force generated by resistance aggravation is eased, as a result, the refractive idle flow loss of water dynamic energy is avoided, the efficiency of converting water energy into mechanical energy is greatly increased, and thereby, the water energy efficiency is increased by 40 percent to 50 percent as against the water energy efficiency of conventional hydroturbine.

Description

Full voltage type hydroturbine
Technical field
The present invention relates to a kind of water turbine, particularly a kind of blade can be around the full voltage type hydroturbine of its core rotation.
Background technique
Existing water turbine, as the patent No. is 87215132.8, open day is a kind of full voltage type hydroturbine of Chinese model utility on March 22nd, 1989, form by casing, main shaft and water wheels, its water wheels middle part is a wheel disc, rotating two groups of blades are installed in the wheel disc both sides, blade and main shaft diameter between the wheel chamber on two sprues are housed respectively, sprue is fixed on the casing.Form two dynamic seal (packing) chambeies respectively by casing, main shaft, wheel disc and two groups of blades and two sprues, current only promote the movable drive of blade water wheels rotation and do not produce scattering current and meander after entering Seal cage, make the efficient of water turbine bring up to 80~90%.But, when this full voltage type hydroturbine is worked, owing to the reason of blade structure, still there is the empty stream consume of refraction of hydrodynamic(al) energy, thereby reduced the efficient of water turbine, the efficient of water turbine is only reached about 80~90%, can not effectively utilize water turbine to greatest extent.
Summary of the invention
The purpose of this invention is to provide a kind of full voltage type hydroturbine, the technical problem that solve is to improve the water energy conversion ratio of water turbine.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of full voltage type hydroturbine, comprise casing, be located at water intake, the main shaft on casing one side and be located at water wheels on the main shaft, the outer of described water wheels is provided with great wheel, described great wheel is separated into upper chamber and lower chambers with water wheels, the middle part of described great wheel moving vane that branch is provided with such as connects respectively in upper chamber and bottom chamber by sharf, is provided with the blade positioning shaft between described two moving vanes.
Sharf of the present invention is located on 1/3rd the position of moving vane.
The inner tail of moving vane of the present invention is provided with to sheet and blade positioning shaft suitable.
The radian of moving vane of the present invention is identical with the external diameter radian of great wheel.
Upper chamber of the present invention and bottom chamber, water inlet are respectively equipped with the water blockoff piece.
The upper end of upper chamber of the present invention and lower chambers is respectively equipped with end cap.
The present invention compared with prior art, the pressure chamber that utilizes moving vane to form, the rotation of promotion runner, eliminated the load speed that fluid dynamic energy runs into, the resistance that slows down increases the weight of the fluid refracting power that produced, and then the empty stream consume of the refraction of having avoided the hydrodynamic(al) energy, improve water greatly and can be converted into mechanical energy efficient, make the water energy efficiency improve 40~50% working efficiency than traditional water turbine.

Embodiment
Below in conjunction with embodiment the present invention is described in further detail.
As Fig. 1, shown in 2, full voltage type hydroturbine of the present invention comprises casing 1, be located at the water intake 10 on casing 1 one sides, main shaft 2 and the water wheels 4 that are located on the main shaft 2, one side of described casing 1 is provided with water intake 10, the center of described casing 1 is provided with main shaft 2, described main shaft 2 is provided with water wheels 4, the outer of described water wheels 4 is provided with great wheel 3, described great wheel 3 is separated into upper chamber 41 and lower chambers 42 with water wheels 4, need five equilibrium and be respectively equipped with a plurality of moving vanes 5 by design in described upper chamber 41 and the lower chambers 42, the radian of described moving vane 5 is identical with the external diameter radian of great wheel 3, be provided with blade positioning shaft 8 between two moving vanes 5, described moving vane 5 is coupling on sharf 6, described sharf 6 is located on 1/3rd the position of moving vane 5, described moving vane 5 is provided with to sheet 51 with the inboard of the same side of blade positioning shaft 8, described suitable to sheet 51 and blade positioning shaft 8, and it is inconsistent when the leaf tail of moving vane 5 resets, describedly between blade positioning shaft 8 and water wheels 4, be provided with water blockoff piece 7, this water blockoff piece 7 is located at respectively in upper chamber 41 and the lower chambers 42, on one side of water intake, the upper end of described upper chamber 41 and lower chambers 42 is respectively equipped with end cap 9, described end cap 9 fixing and sealing moving vanes 5, end cap 9, water blockoff piece 7 and casing 1 form cubic pressure chamber, between described moving vane 5 and the blade positioning shaft 8, leave movable matching gap between moving vane 5 and the casing 1.
When pressure water source enters water wheels 4 by water intake 10, impact moving vane 5, the leaf tail of moving vane 5 is flared on the external diameter of water wheels 4, this moment, moving vane 5 moved in the cubic pressure chamber that end cap 9 and water blockoff piece 7 form, because water can form pressure official post moving vane 5 and move continuously in whole pressure chamber, thereby promote water wheels 4 rotations, can effectively avoid the generation of current scattering and meander phenomenon like this and to the reverse impact power of a back moving vane, and reduce hydrodynamic(al) can the empty stream consume of refraction.When this moving vane 5 turns over above-mentioned pressure chamber section, then enter drain charge chamber section, and the next moving vane 5 in rotating continues to enter the work of pressure chamber section, 5 of the moving vanes of drain charge chamber section under the water wheels action of centrifugal force, the leaf tail of moving vane 5 resets, and conflicts and identical being integral with blade positioning shaft 8, and then turns between the slit of casing 1 and water blockoff piece 7, reenter the pressure chamber section, thereby can work again and again.
The structure of moving vane of the present invention has avoided current in the problem of impacting blade generation part potential energy, also effectively reduced reverse impact to the rotary component generation of back, eliminated the load speed that fluid dynamic energy runs into, the resistance that slows down increases the weight of the fluid refracting power that produced, and then the empty stream consume of the refraction of having avoided the hydrodynamic(al) energy, improve water greatly and can be converted into mechanical energy efficient, thereby further improved the efficient of water turbine, make the efficient of water turbine improve 40%~50% again on the basis of traditional water turbine, this full voltage type hydroturbine also can be used on the steam turbine.
