Abstract
The utility model discloses one horizontal water turbine small flow electricity generating device in dry season, comprise runner (1), described runner (1) is provided with flow channel (2), is one along water (flow) direction horn mouth (3) from large to small at the entrance point of described flow channel (2).The utility model has ingenious, the simple advantage of structure of design, by simple improvement, water turbine set can be met and generate electricity under the streamflow regime of low water head, small flow, extend generating dutation, saved water resources, improve economic benefit.
Description
Technical field
The utility model relates to a kind of small flow electricity generating device, particularly one horizontal water turbine small flow electricity generating device in dry season.
Background technique
At present; in the horizontal unit of routine; when arriving dry season, because incoming flow reduces, head is low, flow is few; be difficult to the requirement ensureing that unit normally runs; power station can only be shut down, and causes these part current to waste to drain, reduce the utilization ratio of unit generation; waste precious water source, have impact on the economic benefit in power station.
Model utility content
The purpose of this utility model be just to provide a kind ofly meet low water head, small flow carries out the horizontal water turbine small flow electricity generating device in dry season that generates electricity.
The purpose of this utility model is realized by such technological scheme, one horizontal water turbine small flow electricity generating device in dry season, comprising runner, described runner is provided with flow channel, is one along water (flow) direction horn mouth from large to small at the entrance point of described flow channel.
Wherein, described runner comprises runner pressed on ring and runner band, and the exterior edge face of described runner pressed on ring is made up of cambered surface and inclined-plane A, and the exterior edge face of described runner band is an inclined-plane B, and described inclined-plane A and inclined-plane B correspondence forms horn mouth.
Owing to have employed technique scheme, the utility model has ingenious, the simple advantage of structure of design, by simple improvement, water turbine set can be met generate electricity under the streamflow regime of low water head, small flow, extend generating dutation, saved water resources, improve economic benefit.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, and horizontal water turbine small flow electricity generating device, comprised runner 1, described runner 1 was provided with flow channel 2 a kind of dry season, is one along water (flow) direction horn mouth 3 from large to small at the entrance point of described flow channel 2.
Further describe, described horn mouth is formed like this: described runner 1 comprises runner pressed on ring 4 and runner band 5, the exterior edge face of described runner pressed on ring 4 is made up of cambered surface 6 and inclined-plane A7, and the exterior edge face of described runner band 5 is an inclined-plane B8, and described inclined-plane A7 and inclined-plane B8 correspondence forms horn mouth 3.
When in the dry season, when current enter into horn mouth 3 place of runner, due to narrowing of horn mouth 3, cause current to become anxious, impact force becomes large, so just makes current have enough strength and impacts runner, rotate.
Claims (2)
1. one kind dry season horizontal water turbine small flow electricity generating device, comprise runner (1), described runner (1) is provided with flow channel (2), it is characterized in that: be one along water (flow) direction horn mouth (3) from large to small at the entrance point of described flow channel (2).
2. as claimed in claim 1 dry season horizontal water turbine small flow electricity generating device, it is characterized in that: described runner (1) comprises runner pressed on ring (4) and runner band (5), the exterior edge face of described runner pressed on ring (4) is by cambered surface (6) and inclined-plane A(7) form, the exterior edge face of described runner band (5) is an inclined-plane B(8), described inclined-plane A(7) and inclined-plane B(8) corresponding formation horn mouth (3).
