SI22869A - Immersion pump with automatic drive - Google Patents

Abstract

Subject of the invention is an immersion pump with automatic drive which during fastening to the bottom of the watercourse receives the driving energy from the dynamic force of water mass movements which it is immersed to. Its entity consists of a pumping part and a system of driving shovel-blades attached on top of it. Half of these shovel- blades constantly keep turning their maximum surface towards the water current, while the other half keeps turning a several times smaller surface against the water current, which results in their common rotation and continuous automatic pumping by the immersion pump.

SUBMERSIBLE PUMP WITH AUTOMATIC DRIVE

The subject of the invention is a self-propelled submersible pump which utilizes the hydrodynamic energy of a moving water mass as a propellant. According to its technical design, the pump can be any of the known technical solutions: piston, peristaltic, with integrated diaphragm, or even centrifugal with the added multiplier to increase the speed required by such a pump. The only technical requirement that the pump must meet is that it must be adapted to long-term operation below the water level. The submersible pump is mounted on a concrete or other base, which is fixed to the bottom of the watercourse whereby the pump is driven by a built-in system of rotating and only adjustable pairs of blades, which the flow of water pushes into rotation, automatically changes their limited operating angle and causes one the sides of the blade turn towards the water

-2their largest surface, while the opposite blades turn their smallest surface at the same time towards the water stream. The invention belongs to class F 01D 7/00 of the international patent classification.

A technical problem that is successfully solved by the invention is the continuous automatic drive of the pump submerged in water without an external mechanical, electrical or other known drive source, since the pump uses solely the propulsion energy taken from the moving water mass. In addition to the energy benefits at an adequate depth of watercourse that can be as deep as ca. 1 meter to 10 meters, and the pump performance is not affected by fluctuations in the water level. It is also easy to manufacture and reliable to operate. From an ecological point of view, the new pump must be able to preserve the natural outward appearance of the watercourse and the landscape, must not pollute the environment and, while operating at the bottom of the watercourse, must not pose a risk to the fish embryo or for the flora and fauna of the watercourse. A particular technical problem that a submersible pump according to the invention has to solve is the pronounced slow rotation of its propeller blades, which must not allow more than one revolution for a maximum of 4 or 6 seconds, regardless of the possible increase in the speed of running water, whereby the pump would start operating at a very low water speed of ca. 0.1 m / sec, and the energy-optimal operation is expected to have a pump at a water velocity in the watercourse of approx. 5.5 m / sec. Due to the risk of injury to living persons or animals, even at extremely high water speeds of approx. 12 m / sec, the speed of rotation of the drive blades should not exceed one revolution in 3.5 seconds.

-3 The submersible pump according to the invention solves the technical problem by receiving a propulsion from its system of radially rotating at least two pairs opposite to the blades which are connected to the common axle in pairs and drive the pump in continuous operation with its common center. whereby, depending on the technical design of the pump itself, the drive connection between the drive blades and the pump is made to a suitable or. technically known way.

I will explain the invention in more detail based on embodiments and corresponding figures, of which:

Fig. 4/4 Side view of a submersible piston pump pump with two pairs of drive blades from whose common axis the drive torque is transmitted to the piston rod and pump piston via a built-in eccentric system.

-4 The self-propelled submersible pump according to the invention, shown in Figures 1/4 and 2/4 in the first embodiment, is peristaltic and is fixed to a concrete or other substrate 8, with its outlet 4 and inlet 5 connections being freely accessible for connecting pipes. At least double-spaced major axes 15 of the peristaltic pump 1, axially 13, 14 bearing the drive blades 11, 11 'on one axis 14 and 12, 12' on the other axis 13, both radially mounted above the pump, crosswise and at different heights rotating the angle defined by the stops 10, the blades 11, 12 being shown in an elevated position relative to the water surface and the direction of the water flow. In the described position of the drive blades and the water flow direction of the blades 11 and 12 shown, they create a large obstacle to the water flow, which causes them to rotate together with the axis 15 of the peristaltic pump in the opposite direction to the clockwise rotation. By rotating the blades 12, 12 'across the direction of the water flow direction, the water flow pushes the blade 12 down and simultaneously raises the blade 12'. From here on until the 180 ° rotation, the blade 12 'will be in active mode and the blade 12 will rotate in reverse direction with minimal water resistance as the flow of water flows. The same will happen with the blades 11, 1T when the entire blade configuration rotates more than 90 ° relative to the position shown in Figure 2/4.

In Figs. 1/4 and 2/4, the peristaltic pump shown may have two pairs of drive blades attached to its main axis 15 or, with less suitable hydrodynamic conditions, may also have three or more pairs of drive blades, which always provide reciprocal connection blades that causes them to synchronize

-5 radial rotation on the horizontal support axes 13 and 14 to which they are mounted.

In order to increase the capacity of the peristaltic pump 1 at its small outer diameter, two or three peristaltic pumps can be mounted on the axis 15 above each other.

In the first embodiment, the pump and drive blades can also be mechanically separated and a submersible peristaltic pump immersed together with a waterproof electric motor mounted on a solid surface, instead of a suitable waterproof protected generator for the production of electrical power to supply the motor of the pump to the main vertical axis 15.

Figure 3/4 shows another embodiment or example. lateral view of submersible pump 2 of centrifugal type and with two pairs of drive blades 11, 1Γ and 12, 12 ', whose common vertical axis 15 is transmitted torque to the centrifugal pump via a rotation multiplier attached to pump 2, which with slow rotation of the drive blades system centrifugal pump significantly increased speed. The drive part of the centrifugal pump with the vapor coupling system works in the same way as described in the first embodiment, the example shown in Figures 1/4 and 2/4.

In the third embodiment, Figure 4/4 shows a side view of a submersible pump 3 of the piston design, in which cylindrical shut-off valves 7 are mounted on the cylinder, one of which enables

-6 water intake into the cylinder and the other water outlet from the cylinder. This self-propelled submersible pump is driven by an eccentrically positioned channel 9 attached to the vertical axis 15 of the drive blade system, which, in the described case, also operates in the same manner as described in the first embodiment, except that the obtained torque moves the piston rod via the eccentrically positioned channel 9. 16 of the piston pump 3, thereby moving the piston to the front or rear position in the pump cylinder, causing water to enter and exit the cylinder.

In the third embodiment shown, several submersible pumps 3 can be erected which simultaneously receive an automatic actuator generated by the dynamic force of movement of the water mass through the eccentrically produced channel 9. Instead of a self-propelled submersible reciprocating pump 3, a suitable diaphragm pump or several diaphragm pumps adapted for continuous operation below the water surface may be installed in its place.

In all embodiments, a self-propelled submersible pump may have two, three or even more pairs of drive blades installed.
