Abstract
The invention discloses a cascade multi-stage hydraulic turbine, which belongs to the field of water energy utilization and mainly solves the problem that the hydraulic turbine can only be arranged at a lower port of the tail end of a water passage in order to achieve high fall and large potential energy and the strong potential energy of the water flow during flow in the delivery water passage is neglected, so that the strong potential energy of the water flow is scattered and damaged after one-time impact at the tail end to cause loss of reutilization value. According to the cascade multi-stage hydraulic turbine, upper rollover hydraulic turbines are repeatedly arranged on a semi-open water passage in a cascade type multi-stage manner; the water flow characteristic is utilized by the structure; the descending potential energy of the water flow is not scattered or damaged during work; conditions are created for repeated use of the potential energy, so that the hydraulic turbines can be repeatedly arranged at multiple stages; the operation direction of blades of the hydraulic turbines are consistent with the water flow impact direction, so that the output loss is effectively reduced; further, a flow regulating valve is arranged in front of each stage of hydraulic turbine, so that the water flow of the blades can be effectively regulated, an ideal operation state is obtained, and the overall descending potential energy of the water flow is not affected.
Description
Technical field
The present invention relates to water and can utilize field, specifically, relate to a kind of ladder-type multi-stage water turbine.
Background technique
Prior art is for asking high drop, large potential energy all water turbine can only be placed in to water channel end end opening, ignored the powerful potential energy of current in carrying the water channel flow process, this potential energy is dispersed after the end one-shot destroy and loses the value reused and run off, form the situation that loss is large, efficiency is low, cost is high, this situation is more aobvious outstanding today at energy-intensive.
Therefore design a kind of can utilize to greatest extent streaming potential and the high water turbine of the little efficiency of loss required for people.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of ladder-type multi-stage water turbine.According to flow characteristics and application, need to adopt the semi open model water channel, its upside with respect to water (flow) direction is the water channel of open state, can save to a certain extent water channel and consume with material.Main structure of the present invention is to be on this semi open model water channel that ladder-type is multistage and to repeat to arrange to put the rolling type water turbine, being about to the rolling type water turbine is arranged on water channel, specifically, on put the rolling type water turbine and comprise the transmission shaft that is connected with the semi open model water channel by bearing support and be arranged at the wheel blade on transmission shaft, and be provided with the gap of passing through for the adjusting current between wheel blade and semi open model water channel.The traffic direction of its wheel blade is consistent with the water impact direction, and this structure can effectively reduce output loss, and during this arrangement works, when the wheel blade rotating speed is synchronizeed with flow rate of water flow, can not disperse or destroy the descending potential energy of current.Can be in optimal operational condition for effectively guaranteeing at different levels to put the rolling type water turbine, the spy arranges in its place ahead respectively and adjusts the stream door, for effectively regulating the current that impact wheel blade, do not affect again its whole descending potential energy, created condition for reusing this potential energy, repeated so step by step to realize designing requirement of the present invention.
The accompanying drawing explanation
Fig. 1 is the structural representation of facing of the present invention.
Fig. 2 is side-looking structural representation of the present invention.
In above-mentioned accompanying drawing, the component names that reference character is corresponding is as follows:
1-semi open model water channel, 2-adjusts stream door, 3-bearing support, 4-transmission shaft, 5-wheel blade.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
As depicted in figs. 1 and 2, this ladder-type multi-stage water turbine adopts semi open model water channel 1, this water channel is open state with respect to the upside of water (flow) direction, the shape of water channel can adopt circular or square or other shapes, should not be considered as the restriction to its structure, and be on the semi open model water channel that ladder-type is multistage and repeat to arrange and put the rolling type water turbine.Putting the rolling type water turbine on being somebody's turn to do comprises the transmission shaft 4 be connected with the semi open model water channel by bearing support 3 and is arranged at the wheel blade 5 on transmission shaft.Specifically, be that the bearing support 3 of putting the rolling type water turbine on this is arranged on to edge on the water channel both sides, make to put the rolling type water turbine and be cross-placed on water channel, and make transmission shaft 4 vertical with the water channel sidewall, consistent with flow direction with the sense of rotation that guarantees wheel blade 5.Wheel blade traffic direction effectively reduce output loss consistent with the water impact direction.And the transverse dimension of wheel blade is slightly less than this semi open model channel width, with reserved corresponding space gap between this water channel and wheel blade, for regulating current, pass through.Putting rolling type water turbine the place ahead at different levels arranges and adjusts stream door 2, by regulating the opening angle of this tune stream door, effectively regulate the current that impact wheel blade, guarantee at different levels that putting the rolling type water turbine can move in the ideal situation, and current can not be dispersed or destroy after impacting wheel blade, still can keep its potential energy to continue descending.Regulate to adjust the opening angle of stream door also can not affect the descending potential energy of integral body of current, therefore this potential energy can be repeatedly used, impact successively at different levels and put the rolling type water turbine and make its operation.Adopt the present invention to utilize to greatest extent streaming potential, effectively reduce loss, raise the efficiency, greatly reduce production costs.
In addition, in concrete application of the present invention, can utilize on water impact and put the rolling type water turbine and generated electricity and export electric energy.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
According to above-described embodiment, just can realize well the present invention.What deserves to be explained is; under prerequisite based on the said structure design, for solving same technical problem, even some that make in the present invention are without substantial change or polishing; the essence of the technological scheme adopted is still consistent with the present invention, also should be in protection scope of the present invention.
