Abstract
The utility model provides a steam turbine or hydraulic turbine turbine blade, the portion increases mobilizable additional blade through the end at the blade, consequently can avoid because of meetting the shut down phenomenon that impurity appears, the utility model provides a novel steam turbine or the hydraulic turbine are closed structure, and owing to design into the inner wall of the cyclic annular casing of turbine and turbine blade's outward flange inseparable laminating and enable turbine blade can free rotating -structure, are similar to the piston structure, consequently make the water that gets into the novel steam turbine or the hydraulic turbine or steam can fully drive turbine blade rotatory and make the energy lost fall to minimum to improve the acting efficiency of water or steam.
Description
Technical field
The utility model relates to the turbine blade of a kind of Novel steam turbine or water turbine and employing thereof.
Background technique
Traditional water turbine is divided into two kinds, and one is impact, a kind of impact type.To be water drive water wheels to rotate from flowing away between blade to impact; Impact type is water slug water wheels.Because between impulse water wheel and outer casing underpart, space is large; water is flushed on water wheels and just falls in lower drain port; water homenergic material is caused to flow away between turbine blade and shell; and then cause loss and the waste of energy; if and gap is little; then easily there is shutdown phenomenon because running into impurity, and then break down, occur danger.
It is all solid matter flabellum that steam turbine is produced, cost of production height not easy care, and steam flows away between flabellum, and drive turbine rotor to rotate, steam is walked between flabellum, causes energy to run off.
Model utility content
For above deficiency, the utility model provides a kind of Novel steam turbine or water turbine and turbine blade thereof, can prevent turbine blade from occurring the phenomenon that knock gently stops because running into impurity, and then avoid the generation of fault, save the energy simultaneously, reduces energy consumption.
The technical solution of the utility model: steam turbine or water turbine turbine blade, comprise the blade body be made up of some blades, the rear flank of each blade is connected with additional blades by rotating shaft, wherein additional blades is blocked by the end of blade is spacing along sense of rotation, and additional blades can rotate around rotating shaft against sense of rotation.
Described additional blades is divided into three parts, lays respectively at terminal part and two sidepieces of blade, and is connected on the rear flank of blade respectively by rotating shaft.
A kind of Novel steam turbine or water turbine, have employed described steam turbine or water turbine turbine blade, turbine blade is installed on and forms in closed cavity by circular shell and both sides end cap, the inwall of additional blades outward edge and circular shell and both sides end cap rotates fits, a place on closed cavity is provided with energy inlet, and another place relative with energy inlet on closed cavity is provided with energy outlet.
The beneficial effects of the utility model: the steam turbine that the utility model provides or water turbine turbine blade, by increasing mobilizable additional blades at the terminal part of blade, therefore can avoid the shutdown phenomenon occurred because running into impurity; In addition, the Novel steam turbine that the utility model provides or water turbine are enclosed construction, and due to the inwall of turbine circular shell and the outward edge of turbine blade are designed to fit tightly and can enable the free rotational structure of turbine blade, be similar to piston structure, therefore make to enter that the water of Novel steam turbine or water turbine or steam can fully drive turbine blade to rotate and that energy dissipation is dropped to is minimum, thus improve the mechanical efficiency of water or steam.
Accompanying drawing explanation
Fig. 1 is the structural representation one of the utility model turbine blade.
Fig. 2 is the structural representation two of the utility model turbine blade.
Fig. 3 is the structural representation of the utility model steam turbine or water turbine.
Embodiment
Embodiment one:
Steam turbine as illustrated in fig. 1 and 2 or water turbine turbine blade, comprise the blade body 1 be made up of some blades, the rear flank 4 of each blade is connected with additional blades 2 by rotating shaft 3, wherein additional blades 2 is blocked by the end of blade is spacing along sense of rotation, and additional blades 2 can rotate around rotating shaft 3 against sense of rotation.Described additional blades 2 is divided into three parts, lays respectively at terminal part and two sidepieces of blade, and is connected on the rear flank 4 of blade respectively by rotating shaft.
Working principle: additional blades 2 is blocked by the end of blade is spacing along sense of rotation, and namely additional blades 2 is attached on the rear flank 4 of blade; When additional blades 2 run into impurity stopped time, additional blades 2 can be upspring action around rotating shaft 3.
Embodiment two:
A kind of Novel steam turbine or water turbine, have employed described steam turbine or water turbine turbine blade 5, turbine blade 5 is installed on and forms in closed cavity by circular shell 6 and both sides end cap, the inwall of additional blades 2 outward edge and circular shell 6 and both sides end cap rotates fits, a place on closed cavity is provided with energy inlet 7, and another place relative with energy inlet 7 on closed cavity is provided with energy outlet 8.
During work, water or steam enter into the dihedral mouth of turbine blade from energy inlet 7, fit because the outward edge of additional blades 2 and the inwall of circular shell 6 rotate, therefore water or Steam Actuation turbine blade 5 rotate, when water or steam rotate to energy outlet 8 along with turbine blade 5, water or steam are discharged, and complete acting process.
