Abstract
The utility model relates to a movable-blade water turbine with an intermediate fixed blade, and rotatable movable blades are arranged on one side plate of a water turbine. An intermediate fixed blade fixed without motions is arranged between the blades and a main shaft, the intermediate fixed blade is sheathed on the main shaft, the movable ends of the blades are contacted with the intermediate fixed blade in the working area, and a water storage cavity is formed from the blades, the intermediate fixed blade and the side plate. The working curve of the intermediate fixed blade contacted with the blades is an extended involute. When the water flow impulses the blades, the ejecting water flow impulses the intermediate fixed blade instead of impulsing the rotating subassemblies. No reversal impulsing force is generated, the blades cling with the outer edge of the water turbine in the returning area, so the resistance of the air to the blades is decreased, and the efficiency of the water turbine is improved by 10-20%.
Description
This utility model relates to a kind of water turbine, the moving vane water turbine of stator in the middle of particularly a kind of having.
The water turbine of prior art is made up of housing, main shaft and water wheels.Water wheels are installed on the main shaft, and fixing blade is arranged above it.Blade drives whole water wheels and main axis rotation under water impact, all parts in its rotating locus line all rotate with blade synchronization.The water turbine of Chu Shouing all is so on the market.Can produce reflection during according to dynamic law water impact blade, produce reverse impact power thereby the current of reflection always impact the parts that rotate later.This reverse impact power has reduced the efficient of water turbine, and this is the shortcoming of prior art water turbine.
Task of the present utility model provides a kind of like this water turbine, and its reflective water flow is not impacted rotary component, eliminates the reverse impact power of reflective water flow basically, improves the efficient of water turbine.
Task of the present utility model realizes as follows: rotating moving vane is installed on the former of water wheels, between blade and the main shaft, overlapping main shaft a fixed middle stator is being installed, the movable end of blade contacts with middle stator in the working area that is subjected to water impact, like this when the water impact blade, stator in the middle of its reflective water flow rushes at, can not produce reverse impact power to rotary component, return when district when entering after the blade drain charge, be close to the water wheels outer because of the centrifugal force relation, can reduce the resistance of air blade.Can improve water wheels efficient 10～20% like this, this is an advantage of the present utility model.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model work schematic representation.
As shown in Figure 1, (1), (14) are former; (2), (10), (12) are housing; (3) be fixed cover; (4), (8), (15), (16), (17) are bearing; (5) be main shaft; (6), (7), (9), (18) are gear; (11) be middle stator, (13) are blade.
Rotatable blade (13) is housed between two formers (1), (14), between blade (13) and the main shaft (5), is overlapping main shaft (5) a middle stator (11) is housed, middle stator (11) is fixed on the fixed cover (3).Fixed cover (3) is fixed on the housing (12), and its endoporus can pass through bearing (15) and be connected with main shaft (5).Preceding former (14) is fixed on the main shaft (5), and back former (1) can pass through bearing (17) and be connected with fixed cover (3).In order to strengthen the stability of water wheels, can on back former (1), fix a gear (18), gear (18) meshes with the gear (9) that is installed on the housing (12), and drives the gear (6) that is fixed on the main shaft (5) by the in-line gears (7) of gear (9).
As shown in Figure 2, (13a) be the blade of working area; (13b) for returning the blade in district; (11) be middle stator, thereby arrow A is represented can not produce reverse impact power to middle stator reflection behind the water impact blade.The movable end of the blade of working area (13a) is formed reservoir with middle stator (11) contact and with two formers under water impact.Blade after the drain charge (13b) is close to water wheels wheel outer because of centrifugal force relation returning the district, can reduce air and the spray resistance to blade.Under water impact, blade drives former and drives main axis rotation by former.
The working curve that middle stator (11) contacts with blade can be a prolongation involute, and its Base radius is 1/4～3/4 of a water wheels radius, preferably 1/3～2/3.Base radius and length of blade sum are slightly larger than the water wheels radius.
Claims (3)
1, a kind of water turbine is made up of housing, main shaft and water wheels, it is characterized in that: rotatable blade (13) is arranged on water wheels former (1), (14); A fixed middle stator (11) that is enclosed within on the main shaft (5) is arranged between blade (13) and the main shaft (5); The movable end of blade (13) contacts with middle stator (11) in the working area.
2, according to the water turbine of claim 1, it is characterized in that: the working curve that middle stator (11) contacts with blade (13) is one and prolongs involute, and its Base radius is 1/4～3/4 of a water wheels radius, preferably 1/3～2/3.
3, according to the water turbine of claim 1 or 2, it is characterized in that: middle stator (11) is fixed on the fixed cover (3), fixed cover (3) is fixed on the housing (12), preceding former (14) is fixed on the main shaft (5), back former (1) is connected with fixed cover (3) by bearing (17) and afterwards is fixed with a gear (18) on the former (1), gear (18) meshes with the gear (9) that is installed on the housing (12), and drives the gear (6) that is fixed on the main shaft (5) by the in-line gears (7) of gear (9).
