Description

Portable water turbine device

Technical Field

The invention relates to the technical field of hydroelectric power generation equipment, in particular to a portable water turbine device.

Background

As is well known, hydroelectric power generation has the characteristics of low power generation cost, small investment scale, quick response, no environmental pollution and the like. The current running mode of water turbine power generation is as follows: the combined-flow, axial-flow, diagonal-flow and through-flow impact turbines using water flow pressure energy and kinetic energy and the pelton, diagonal-flow and double-impact turbines using water flow energy, wherein the turbines commonly used in China mainly comprise axial-flow, mixed-flow and pelton, which have advantages respectively, but are rotated by impact force generated by high-level gravitational potential energy of water, and have similar disadvantages: on one hand, a high water head is needed, so that a water storage dam needs to be built to raise the water level, and the investment is large; on the other hand, because the water flows out at the nozzle, the potential energy conversion efficiency of the water is low due to the excessively wide nozzle, so that the river with small flow rate has no commercial development value; in the third aspect, the water bucket is smooth, water rushing into the water bucket directly rushes out of the water bucket, the water retaining pressure of the water bucket is small, and partial gravitational energy and water head impact potential energy are offset.

At present prior art's pelton turbine when the operation, the resistance that the bucket can receive rivers when leaving the sleep, moreover, remain in the water bucket can fall into the below when the whereabouts in, thereby just so reduced the rotational speed of runner great influence the generating efficiency of the hydraulic turbine.

Disclosure of Invention

The present invention is directed to a portable water turbine apparatus to solve the above problems.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a portable hydraulic turbine device, includes runner and water bucket, the water bucket is bowl dress structure, the rear end wall of water bucket still passes through reinforcing plate and runner fixed connection, still be provided with a plurality of water conservancy diversion walls on the rear end wall of water bucket, arbitrary two are adjacent constitute the water conservancy diversion canal between the water conservancy diversion wall, the transversal trapezium structure of personally submitting of water conservancy diversion canal, the water conservancy diversion layer has still been seted up on the rear end wall of water bucket, be linked together through the round hole between water conservancy diversion layer and the water conservancy diversion canal.

Preferably, the reinforcing plate is connected with the central point of the rear end wall of the water bucket, and the included angle between the reinforcing plate and the rotating wheel is smaller than ninety degrees and larger than forty-five degrees.

Preferably, the width of the diversion layer is half of that of the water bucket, and the diversion layer is arranged at one end far away from the rotating wheel.

Preferably, a plurality of round holes are formed in any one of the diversion channels along the extension direction of the diversion channel.

Preferably, the number of the water buckets is a plurality, and the water buckets are distributed on the outer wall of the rotating wheel in an annular structure.

Compared with the prior art, the invention has the beneficial effects that: when the water bucket is separated from the water surface, the reinforcing plate forms an inclined included angle with the water surface so as to facilitate the water flow to flow down, and then the water flow can be dispersed through the flow guide channel and the flow guide wall, so that the resistance is reduced; secondly, the diversion layer below the diversion channel can also better help the bucket reduce the impact force between the rear end wall of the bucket and the water flow when the bucket operates in water, thereby better improving the power generation efficiency.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a portable hydraulic turbine device, includes runner 1 and bucket 2, bucket 2 is bowl dress structure, the rear end wall of bucket 2 still is through reinforcing plate 3 and 1 fixed connection of runner, still be provided with a plurality of water conservancy diversion walls 4 on the rear end wall of bucket 2, arbitrary two are adjacent constitute water conservancy diversion canal 5 between the water conservancy diversion wall 4, the transversal trapezium structure of personally submitting of water conservancy diversion canal 5, water conservancy diversion layer 6 has still been seted up on the rear end wall of bucket 2, it is worth noting, the width on water conservancy diversion layer 6 is half of bucket 2, just water conservancy diversion layer 6 sets up the one end of keeping away from runner 1, be linked together through round hole 7 between water conservancy diversion layer 6 and the water conservancy diversion canal 5.

It is noted that the reinforcing plate 3 is connected with the central point of the rear end wall of the water bucket 2, and the included angle between the reinforcing plate 3 and the runner 1 is less than ninety degrees and more than forty-five degrees.

It should be noted that a plurality of circular holes 7 are formed in any one of the diversion channels 5 along the extending direction of the diversion channel 5.

It is worth noting that the number of the water buckets 2 is a plurality, and the water buckets 2 are distributed on the outer wall of the rotating wheel 1 in an annular structure.
