Background technique
The water wheels unit is a kind of device that water flow dynamic energy is converted to mechanical energy.It mainly comprises the runner that is arranged in current, and a plurality of blades are installed on the runner, by the impact of current to blade, drives the runner rotation, and by with the output mechanism of the coaxial setting of runner mechanical energy being exported.Existing water wheels unit is generally horizontal, and blade generally is designed to be beneficial to streamlined that current pass through, when increasing current by blade to the impact force of runner circumferencial direction.Though the water wheels unit technology of this form is ripe, the part that but comes with some shortcomings, as, need continually could drive the runner rotation than big water quantity, its application is restricted etc.
At the problems referred to above point, before the applicant a solution has been proposed, this scheme is designed to arc with the blade profile on the runner, makes blade form the cavity volume that can collect current, no matter water yield size all can drive the runner running after holding full water in the cavity volume.This scenario-frame is simple, even also can work wide accommodation under little water yield situation.The claimant also with this scheme application patent, this number of patent application is 2007200536902.But this scheme still has deficiency, and after turning to below the straight horizontal radial line with runner when filled with water in the blade, the water in the blade can slowly flow out and this blade is reduced the active force of runner, and the potential energy of current is not fully utilized.
The model utility content
The technical problems to be solved in the utility model provide a kind of structure simpler, to the sufficient combination type water turbine group of the potential energy utilization of water.
According to above-mentioned technical requirements, the utility model is realized by the following technical solutions:
A kind of combination type water turbine group, comprise frame and be installed on runner in the frame, power is connected between runner rotating shaft and the generator, the runner periphery is evenly equipped with blade, be provided with guide groove on the runner next door, guide groove is obliquely installed, and the guide groove upper end is positioned at runner straight horizontal radial line below, lower end next door is provided with the auxiliary runner mechanism that the current that flow out in the guide groove are utilized again, and power is connected between auxiliary runner mechanism output shaft and the generator.
Above-mentioned auxiliary runner mechanism comprises two synchronizing wheels that are installed on up and down on the frame, and two synchronizing wheels connect by band synchronously, in band arranged outside synchronously the sheet that collects that docks with the guide groove lower end is arranged.Synchronizing wheel is connected with generator power with rotating shaft with runner by connecting band and steering gear group.Simultaneously, be arc with blade with collecting the sheet cross section, form the cavity volume that collects current.After current entered runner bucket, runner began to rotate, when blade goes to runner straight horizontal radial line when following, water on the blade slowly flows out from blade and flows in the guide groove, flow to along guide groove again and collect on the sheet, and drive band and synchronizing wheel action synchronously, form the power output of rotation.
In order to make full use of the water that flows out from runner bucket more, above-mentioned guide groove is be arranged in parallel a plurality of, each guide groove upper end edge runner arc shooting.
In order to eliminate the adverse effect of outside current to runner and auxiliary runner mechanism, the guide plate that the outside current of guiding accurately impact runner bucket is installed on the frame above the runner, and auxiliary runner mechanism is provided with the baffle plate that prevents the auxiliary runner mechanism of outside current reverse impact.
The utility model can directly be set up auxiliary runner mechanism in existing water wheels unit, make, install simple, and the potential energy of water is utilized more fully, has improved the conversion efficiency of energy, and practicability is stronger.
Description of drawings
Accompanying drawing 1 is the utility model embodiment internal structure schematic representation.
Embodiment
For the ease of those skilled in the art's understanding, will tie specific embodiment and accompanying drawing below the utility model structural principle will be described in further detail:
As shown in Figure 1, the water wheels unit utilization of resources that this programme disclosed is abundant, can improve the conversion ratio of streaming potential to mechanical energy to greatest extent.The water wheels unit of this programme comprises frame 1, and runner 2, two synchronizing wheels 41 and the guide groove 3 between synchronizing wheel 41 and runner 2 by rotating with 42 connections synchronously are installed in frame 1.The periphery of runner 2 is evenly equipped with blade 21, two synchronizing wheels 41 and vertically installs, and is evenly equipped with blade 21 be arranged in parallel with 42 outsides synchronously and collects sheet 43.Guide groove 3 tilts to install, and the upper end is arranged in blade 21 belows and is used to collect the water that drops from blade 21, and the lower end connection collects sheet 43, is used for being directed at from the water that blade 21 flows out collecting the sheet 43.Blade 21 is an arc with collecting sheet 43 cross sections, forms water containing cavity volume.After water enters from frame 1 top, press down blade 21 and make runner 2 rotations, there is certain water yield in blade 21 cavity volumes simultaneously.When blade 21 rotates to runner 2 straight horizontal radial lines when following with runner 2, blade 21 tilts gradually, water in the blade 21 flows out to fall into after the guide groove 3 to flow to collect sheet 43 and drive along guide groove 3 is with 42 and synchronizing wheel 41 actions synchronously, and synchronizing wheel 41 rotates and forms power output.
In order to be more conducive to collect the water that flows out in the blade 21, guide groove 3 is a plurality of for what be arranged in parallel up and down, each guide groove upper end edge runner 2 arc shooting.Move downward the process below runner 2 straight horizontal radial lines at blade 21, the water that spills from blade 21 can be received by guide groove 3, and is more abundant to the utilization of water.
In this programme, the power of runner 2 and synchronizing wheel 41 is all by same rotating shaft output, because the sense of rotation of runner 2 and synchronizing wheel 41 is opposite, be connected by steering gear group 6 between synchronizing wheel 41 and the runner 2, steering gear group 6 is made up of two pitch wheels, two gears are connected with synchronizing wheel 41 with runner 2 by connecting band 5 respectively, realize the transmission of power.
Enter frame 1 and accurately impacted blade 21 on the runner 2 in order to be beneficial to outside current, frame 1 is provided with guide plate 11, simultaneously, collects sheet 43 in order to prevent the current reverse impact, is provided with baffle plate 12 in the frame 1 of synchronizing wheel 41 top positions.
The utility model promptly can be applicable in the large-scale water generating unit, also can be applied in the small-sized energy conversion device, in Compact Power Plant and the medium equipment of industrial circulate water.
Such scheme is one of preferable implementation of the utility model; in addition; also there are other mapped structures in the utility model, need to prove, is not breaking away from any conspicuous modification done under the present utility model design prerequisite all within the utility model protection domain.
