Description

A streamlined blade water turbine

technical field

The utility model relates to a water turbine, in particular to a streamline blade water turbine capable of working in wind force and various natural fluids.

Background technique

At present, the whole world is looking for green, clean and sustainable energy to replace the thermal energy that affects the atmospheric environment. Using wind power and hydropower to generate electricity can reduce the annual pollution to the atmosphere, which is the research direction of various countries. Taking the water-driven turbine as an example, its main structure is basically divided into bucket type, jet type and turbine type. A hydroelectric power station must build a dam reservoir, and then use the potential energy of water to drive the water turbine to drive the generator set to generate electricity. The water turbine of above-mentioned structure has following weak point: (1) large-scale water turbine unit also needs potential energy embankment except self and supporting equipment expensive cost, and its investment is very huge; It also wastes a lot of water conservancy resources, and like the Three Gorges, the resource storage site of Gezhouba can not be found casually; (3) the entrance and exit of potential energy water are fixed.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Referring to accompanying drawings 1 and 2: the streamline blade water turbine consists of a base 1, an output shaft 2 and a water wheel 3. The gist of the utility model is that the water wheel 3 has been technically improved, that is: the water wheel 3 is composed of two shell plates 8 and at least three blades 4, and the blades 4 are installed on the two shell plates through the rotating shaft 5. 8, the blade 4 can rotate around the rotating shaft 5, on the two shell plates 8 on the same side as the rotating shaft 5, starting from the outer edges of the two shell plates 8, an outer limit that limits the rotation angle of the blade 4 around the rotating shaft 5 is sequentially installed and fixed. Position rod 6 and inner limit rod 7.

The blade 4 is a wing-shaped streamlined body plate structure.

The rotating shaft 5 can be fixed between two shell plates 8, and the blade 4 is hinged to the rotating shaft 5; or the blade 4 is fixedly connected to the rotating shaft 5, and the two ends of the rotating shaft 5 are clamped by the two shell plates 8 to form a hinge.

No matter in which direction the fluid flows, the streamline blade turbine always rotates in one direction, and if the water wheel is turned 180 degrees around the horizontal axis, the streamline blade turbine always rotates in the other direction.

Whether it is gas or liquid, as long as there is a certain flow rate, the streamlined blade water turbine can be driven to drive the generating set to generate electricity, or do other things.

How it works: First, it is assumed that the fluid flows in a fixed direction. When the front of the blade 4 is pushed by the fluid, the blade 4 rotates, and its tail moves closer to the inner limit rod 7 and is supported. At this time, the fluid exerts pressure on the blade 4, and this pressure pushes the water wheel 3 to rotate in a fixed direction , when the water wheel 3 continues to rotate, the water-facing surface of the blade 4 changes. When the water wheel 3 rotates to a certain angle, the back of the blade 4 faces the water. Part rotates outward limit rod 6 and obtains the support of outer limit rod 6. The blade 4 does not produce any resistance to the water wheel 3 during the above-mentioned rotation process. The water wheel 3 continues to rotate, and because the blade 4 is a wing-shaped streamlined body plate structure, as the wings of an airplane, it generates lift in the fluid, so the water wheel 3 does not produce any resistance. The water wheel 3 continues to rotate, and the blade 4 is brought to the position narrated at the very beginning again, and the rotation of the next cycle is started.
