Description

Pipe type spiral hydraulic power machine

Technical Field

The utility model relates to a hydraulic power device, in particular to a tubular spiral hydraulic power machine.

Background

The existing water turbine is mostly horizontal, namely, water flow enters the water turbine and pushes blades to rotate in the horizontal direction, and power is output outwards by blade shafts. Most hydroelectric generators as they exist are of this type of construction. The water turbine with the structure has the problems that hydraulic power is not fully converted into mechanical power, hydraulic resources are not fully utilized, and a considerable part of water energy remained in water flow from the generator is wasted. Because the flowing water flow flows from a high place to a low place, besides kinetic energy, pressure energy generated by the weight of the fluid is also generated, and the angle is horizontal, the flowing water flow cannot do work outwards. There is a need for an improved structure.

Disclosure of Invention

Therefore, the utility model provides a tubular spiral hydraulic power machine, make it can fully utilize rivers can outwards do work to improve the energy conversion efficiency of current hydraulic power machine, in order to overcome prior art's not enough.

The purpose of the utility model is realized by the following means:

a tubular spiral hydraulic power machine is composed of machine frame, fixed axle, central tube, external tube and spiral plate, and features that the fixed axle is vertically installed between machine frame and axle seat, the central tube is installed to the fixed axle, the spiral plate is connected between central tube and external tube to rotate around the fixed axle, the upper end of external tube has water inlet hopper, and the external tube has power output wheel.

The spiral plate is 1-3 parallel spiral plates.

The number of turns of the spiral plate is 1-3.

The shaft seat of the fixed shaft is a pier-shaped seat, the upper end of the shaft seat extends into the outer pipe, and a water collecting bucket is arranged around the pier-shaped seat so as to lead the outlet water to downstream hydraulic equipment for further work. The water collecting bucket and the pier-shaped seat can be connected by spokes.

The water collecting hopper is connected with a water inlet pipe of the hydroelectric generator.

The water inlet hopper is of a funnel structure, and a bottom opening is welded at an upper end opening of the outer pipe.

The power output wheel can be a belt pulley, and can also be a gear or a chain wheel.

The upper end of the fixed shaft can be fixedly arranged on the frame through a flange plate, a shaft clamp and a shaft sleeve.

The fixed shaft is matched with the central pipe through a bearing.

The working principle of the utility model is as follows:

the natural water flow is introduced into the water inlet hopper from the direction of the spiral plate and flows through a spiral channel enclosed between the spiral plate and the central pipe and the outer pipe, the spiral plate rotates around a fixed shaft together with the central pipe and the outer pipe under the action of water flow speed and self gravity, and the power output wheel on the outer pipe barrel body transmits power to a working machine such as a generator. After water flows out of the outer pipe, the water falls into a water collecting hopper at the pipe opening, and then flows into a downstream water turbine and other devices to further do work.

Because the water flow flows in a vertical spiral shape, the kinetic energy and the pressure energy generated by the self weight of the water body also play a role in working when the spiral plate is pushed to rotate, so that the natural water power is more fully utilized.

The utility model discloses can independently install and promote the generator work, also can insert the anterior segment of ordinary generating set's inlet tube, reach the purpose of make full use of hydroenergy.

The utility model discloses simple structure, simple to operate is swift, easy popularization.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1-3, the fixed shaft 10 is a vertical shaft made of steel bar, the lower end of the fixed shaft is inserted into the shaft seat 12, the upper end of the fixed shaft is fixed to the frame 1 by a flange 2, or the fixed shaft can be fixed to the frame 1 by a fitting such as a shaft sleeve. As mentioned above, the axle seat is a mound-like structure to securely hold and keep the dead axle vertical. The two ends of the central tube 9 are provided with clapboards, and the bearing 6 is sleeved on the fixed shaft and fixed at the clapboards and sealed and fixed by the bearing cover plate 5 and the bearing cover screws 4.

The outer pipe 7 is concentric with the central pipe 9, and the two pipes are connected and fixed by a spiral plate 8. The spiral plate 8 can have 1-3 strands which are parallel to each other, the spiral plate is preferably screwed for 1-3 circles, unnecessary resistance is generated, and the spiral plate, the central pipe and the outer pipe are connected into a whole in a welding mode. The water inlet hopper 3 is an open funnel shape, and the bottom opening and the upper end opening of the outer pipe are welded together to form a whole. Maintaining concentricity and dynamic balance is important because it is guaranteed to rotate with the outer tube, otherwise, large eccentric forces would wear parts during operation.

The power output wheel 13 is directly fixed on the outer tube body, and can be a gear, a belt pulley or a chain wheel, and can be determined according to the connection and transmission convenience and requirements with the working machine.

The water collecting bucket 13 is fixed on the ground and can be connected with the shaft seat through a spoke structure, namely, the shaft seat is supported and fixed on the water collecting bucket through spokes without influencing water outlet. The frame 1 is generally made of steel by welding.

The parts and reference numerals not mentioned are as described above.
