The water turbine has the advantages of simple structure, reliable operation and high efficiency, and can be arranged on a river with wide river surface and gentle river flow, so that the flow of the water is converted into the rotation of the water turbine to be output. When the water turbine is arranged, the river bottom can be reinforced and the river bank can be surrounded at the riverway provided with the water turbine, so the flow velocity of the water within the riverway is improved and power is generated by the rotation of the water turbine.

Description

A kind of water turbine

Technical field

The utility model relates to a kind of water turbine, particularly a kind of water turbine of using on the water surface that flows.

Background technique

The machine that carries out the mechanical energy conversion between the water of liquid and solid machinery is called hydraulic machinery, the water turbine that the kinetic energy of current is converted to mechanical energy is called impulse turbine, in the water power plant, water in the upper pond is guided water turbine into through aqueduct, the rotation of promotion rotary wheel of water turbine drives generator for electricity generation.The pressure of current is constant in the working procedure, mainly is the conversion of kinetic energy; The water of finishing merit then passes through the tail water row of conduits downstream.Head is high more, flow is big more, and the output power of water turbine is also just big more.

Water turbine has main shaft, main shaft is a pto, main shaft upper edge main shaft has axially uniform, equal-sized blade, blade have runner outward, and runner has spiral case outward, water turbine is installed on the river surface, the blade of water turbine is subjected to the impact rotation of current, thereby drives engine revolution, and motor can send electric current.This water turbine is also referred to as impulse turbine.This water turbine is installed in normally that river surface is narrower, on the river that The turbulent river crashes its way through, or in the turning in river, the place that flow velocity is fast, the impact that utilizes current converts the kinetic energy of current to electric energy, in the prior art, be not installed in the river surface broad, the water turbine on the river that the water flows gently.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind ofly can be installed in the river surface broad, the water turbine on the river that the water flows gently.

The utility model is realized with the following method.

Water turbine has main shaft, there is circular end plate the both sides of main shaft, the spindle nose at main shaft two ends stretches out from end plate, on the main shaft, be evenly equipped with four the long strip blades parallel between two circular end plate with the axial direction of main shaft, the outside of long strip blade is on the outer peripheral surface of circular end plate, angle between the adjacent blades is 90 degree, also be evenly equipped with four long strip half vanes along the circular end plate circumferencial direction between two circular end plate, the outside of half vane is on the outer peripheral surface of circular end plate, angle between each half vane and adjacent two the long strip blades is 45 degree, the width of half vane is 1/2nd to 1/3rd of a blade, is with steel wire in the outside of long strip blade and half vane and strengthens hoop.

The utility model can be erected on the mobile water surface, the fixing earlier bearing support that matches with main shaft on the water surface that flows, axis between the bearing support is parallel with horizontal plane, the axis between the bearing support and the flow direction of water are perpendicular, the spindle nose of main shaft is installed on the bearing support, allows circular end plate insert next section of the water surface, the degree of depth of insertion is less than the radius of circular end plate, water can promote the utility model and rotate when flowing, the spindle nose of main shaft can be rotating output.

The utility model is simple in structure, and is reliable, efficient is high, can be installed in the river surface broad, above the river that the water flows gently, the mobile rotation that converts water turbine to of water exported away.When the utility model is installed, can reinforce the river bed in the river course that model utility is installed and crowd around the riverbank, improve the flow velocity of water in the river course, utilize the rotation generating of this water turbine.

Embodiment

Among Fig. 1, water turbine has main shaft 1, there is circular end plate 2 both sides of main shaft, circular end plate can be that circular dull and stereotyped end plate also can be circular spoke plectane, the spindle nose 3 at main shaft two ends stretches out from end plate, on the main shaft, be evenly equipped with four the long strip blades 4 parallel between two circular end plate with the axial direction of main shaft, the outside 5 of long strip blade is on the outer peripheral surface of circular end plate, angle between the adjacent blades is 90 degree, circumferencial direction along circular end plate between two circular end plate also is evenly equipped with four long strip half vanes 6, the outside 13 of half vane is on the outer peripheral surface of circular end plate, angle between each half vane and adjacent two the long strip blades is 45 degree, the width of half vane is 1/2nd to 1/3rd of a blade, is with steel wire in the outside of long strip blade and half vane and strengthens hoop 13.

Among Fig. 2, circular end plate is circular dull and stereotyped end plate 7.

Among Fig. 3, circular end plate is circular spoke end plate.Circular spoke end plate has cylindrical chow ring 8 and spoke 9.

Distance between two bearing supports of water turbine can be corresponding with the width of river surface.If on the river of river surface broad, set up, need the main shaft of water turbine very long, long main shaft is easy to generate bending deflection, on the very wide river of river surface, set up for convenience, long strip blade and half vane between the circular end plate at the utility model two ends can be divided into multistage, have between every section at interval, an end of every section is connected with the sectioned plate identical with circular end plate.On the main shaft between two sectioned plates middle bearing bracket can be installed, the supporting frame of upright middle bearing bracket in the river course.The foundation of segmentation be allow main shaft can not produce bigger bending deflection.

In the circle 4, long strip blade between the circular end plate and half vane can be divided into two
