Abstract
The utility model discloses a near suspension type impeller. Blades of the impeller is formed by two rectangular plates with an inclined angle of 30 degrees to 150 degrees or two triangular plates with an inclined angle of 30 degrees to 150 degrees, preferably, the inclined angle of the two rectangular plates or the two triangular plates ranges from 40 degrees to 60 degrees, at least one reinforcing support is arranged between the two rectangular plates or the two triangular plates, the impeller density is smaller than or equal to the water density, so that the impeller is enabled to suspend or float in water. According to the impeller, side plates are not arranged at two side ends of the blades, therefore water is convenient to flow out from two sides of the blades, and the efficiency for converting tidal energy into a rotational energy is high; and additionally, the impeller is simple in structure and convenient to process.
Description
Technical field
The utility model relates to hydroelectric installation, especially a kind of nearly floating type impeller.
Background technique
Tidal energy is not only a kind of energy of cleaning, and aboundresources, and energy is huge.To the development and use of tidal energy, be the great research topic of the world today at energy field.Yet, in the existing technology, utilizing the tidal power generating device of tidal power, the blade of its impeller basically all is a propeller type, the defective of its existence is: the efficient that tidal energy is converted into rotation function is not high.
I proposed a kind of impeller at own authorized " tidal power generating device " in (ZL201120133570.X), and on this basis, the utility model has carried out further improvement again.
The model utility content
The purpose of the utility model is: a kind of nearly floating type impeller is provided, and it is simple in structure, and is easy to process, and it is higher that tidal energy is converted into the efficient of rotation function.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
A kind of nearly floating type impeller of the utility model, the blade of said impeller are to be that the rectangular plate of 30-150 degree constitutes by two angles, or are that the triangular plate of 30-150 degree constitutes by two angles.
The angle of said two rectangular plates or two triangular plates is 40-60 degree, between said two rectangular plates or two triangular plates, is provided with a reinforcement support at least.
The density of said impeller is less than or equal to the density of water, it is in water suspends or floating condition.
The beneficial effect of the utility model is: technique scheme, the blade of impeller are to be that the rectangular plate of 30-150 degree constitutes by two angles, or are that the triangular plate of 30-150 degree constitutes by two angles; Preferred angle is 40-60 degree, the blade of this structure, and two side ends is not established side plate; Being convenient to water flows out from the both sides of blade; Utilize the efficient of tidal energy best, and it is simple in structure, easy to process.
Further beneficial effect is again: impeller is nearly floating type impeller; The density of impeller is less than or equal to the density of water; Impeller is in water suspends or floating condition, this structure makes impeller be in the state of minimum drag all the time; All or part of is worked in water, makes the energy that utilizes morning and evening tides that device can maximal efficiency.
Description of drawings
Fig. 1 is the structural representation of the nearly floating type impeller of the utility model;
Fig. 2 is the A-A generalized section of nearly floating type impeller among Fig. 1;
Fig. 3 is first kind of blade structure schematic representation of nearly floating type impeller among Fig. 1;
Fig. 4 is second kind of blade structure schematic representation of nearly floating type impeller among Fig. 1.
Embodiment
To shown in Figure 4, a kind of nearly floating type impeller of the utility model, the blade 0151 of its impeller 015 are to be that the rectangular plate of 45 degree constitutes by two angles, between said two rectangular plates, are provided with two and strengthen supporting 0152 like Fig. 1.The density of impeller 015 is less than or equal to the density of water, it is in water suspends or floating condition.The blade 0151 of this structure, two side ends is not established side plate, is convenient to water and flows out from the both sides of blade 0151, utilize the efficient of tidal energy best, and it is simple in structure, and is easy to process.Impeller is nearly floating type impeller, and promptly the density of impeller is less than or equal to the density of water, impeller is in water suspends or floating condition; This structure; Make impeller be in the state of minimum drag all the time, all or part of is worked in water, makes the energy that utilizes morning and evening tides that device can maximal efficiency.
The above; Preferable case study on implementation for the utility model; Be not that the utility model is done any restriction, everyly any simple modification that above embodiment did, change and equivalent structure changed, still belong to the protection domain of the utility model according to the utility model technical spirit.
Claims (3)
1. nearly floating type impeller is characterized in that: the blade (0151) of said impeller (015) is to be that the rectangular plate of 30-150 degree constitutes by two angles, or is that the triangular plate of 30-150 degree constitutes by two angles.
2. nearly floating type impeller according to claim 1 is characterized in that: the angle of said two rectangular plates or two triangular plates is 40-60 degree, between said two rectangular plates or two triangular plates, is provided with a reinforcement support (0152) at least.
