Abstract
Description
Technical Field
[0001] The utility model relates to a power generation water pumping device, belonging to the technical field of water pumping facilities. Background Art
[0002] The traditional water turbine pump is an energy-saving and environmental protection water pumping machine driven by water power. It combines the functions of a water turbine and a centrifugal pump. The water flow drives the water turbine to rotate, and then drives the impeller of the water pump to rotate, realizing the lifting of water. The water turbine pump has a simple structure, convenient operation, and does not require external energy. It directly uses the natural head of water to work, with significant energy-saving and environmental protection advantages. It is widely used in fields such as farmland irrigation, urban water supply, and aquaculture, providing strong support for the efficient utilization of water resources. With its unique operation mode and economic and environmental protection characteristics, the water turbine pump has become an indispensable part of modern water conservancy project construction.
[0003] The water turbine pump generates centrifugal force through the rotation of the impeller, and uses this force to lift water from a low place to a high place, realizing continuous water delivery operations. The kinetic energy generated only by the head difference of the water turbine pump itself cannot drive the water turbine pump to rotate, and the kinetic energy generated only by the head difference cannot make the water turbine pump work efficiently. The existing small head difference leads to a small water flow, and the water does not have enough flow velocity to drive the impeller in the water turbine to rotate quickly, and water pumping cannot be carried out.
[0004] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of implication that this information constitutes the prior art already known to those of ordinary skill in the art.

[0020] Compared with the prior art, the beneficial effects achieved by the present utility model:
[0021] Based on the traditional water turbine pump, while pumping water with the water-lifting device designed in this application, the kinetic energy of the water is converted into electrical energy and stored; when it is necessary to increase the water-lifting volume for irrigation, the generated electricity is used to drive the water pump to lift water through an electric motor, inheriting the green and environmental protection characteristics of the traditional water turbine pump, while increasing the water-lifting efficiency and lift, solving the problem of low utilization efficiency of water kinetic energy, and having strong practicability.
[0022] Our device solves the problem that the small water flow caused by the small existing water level difference (the small flow rate means the small flow velocity). Without sufficient flow velocity of the water, the impeller inside the water turbine cannot be driven to rotate rapidly, so water cannot be lifted. This is an installation diagram of a water turbine pump without the power generation part. There is a height difference in the device itself, but the water level difference formed by the height of the device itself is sometimes not enough for water lifting. Most of the time, a water dam or water retaining facility needs to be built above the water source to increase the water level drop, and in this way, the flow velocity of the water is increased. When our device is added with the power generation part, when the water volume is sufficient, electricity can be generated and stored for use in the dry season when the water volume is small and the flow velocity of the water is small, and then an electric motor is used to lift water.
[0023] So it solves the problem of installing water retaining facilities upstream. BRIEF DESCRIPTION OF THE DRAWINGS

The main shaft of the water turbine pump 10 drives the driving wheel 6 to rotate, and the driving wheel 6 drives the driven wheel 7 to rotate through the transmission belt 8, so that the driven wheel 7 drives the gear box 3 and the rotating shaft of the generator 2 to rotate, so that the generator 2 generates electricity and is transmitted to the power storage device 4 through the first wire. The electricity stored in the power storage device 4 is used to supply the motor 5 through the second wire to drive the driving wheel 6 to drive the water turbine pump 10 to rotate, so as to solve the problem that when the water flow speed acting on the water turbine pump 10 is small, the main shaft of the water turbine pump 10 is driven to rotate by the motor 5, thereby completing water pumping.
[0031] Optionally, a clutch 9 is provided on the output shaft of the motor 5, and an on-off switch is provided on the second wire. The clutch plate and the friction plate on the clutch 9 cooperate to control the rotation of the output shaft of the motor 5. That is, the on-off operation is performed, and the power storage device 4 provides power support for the motor 5. At this time, the clutch plate and the friction plate are combined, and the motor 5 starts to rotate. When the on-off switch is turned off, the motor 5 stops rotating.
[0032] Optionally, the power generation and water pumping device further includes a seal 11, which is tightly sleeved on the main shaft of the water turbine pump 10 and fits tightly with the top of the water turbine pump 10. This prevents water from overflowing from above the main shaft of the water turbine pump 10 and soaking various components in the power generation box 1 arranged above, thereby increasing the service life of various components in the power generation box 1 and reducing the frequency of maintenance and replacement.
[0033] Optionally, the generator box 1 and the water turbine pump 10 are screwed together by a plurality of screws, so as to facilitate the separation of the water turbine pump 10 and the generator box 1 .

The motor 5 is sleeved in the fixing ring 14 and fixedly connected to the fixing ring 14 by welding.
[0035] Optionally, an insertion groove is provided on the outer side of the fixed ring 14, and the top ends of the support rods 15 are respectively inserted into the corresponding insertion grooves, which facilitates the quick removal of the motor 5 from the power generation box 1.
[0036] Optionally, the left mounting bracket 12 includes a fixing plate 16, side rods 17 and support columns 18. The fixing plate 16 is fixed between the two side rods 17. The top ends of a plurality of support columns 18 are respectively fixedly connected to each side rod 17, and the bottom ends of the plurality of support columns 18 are fixedly arranged at the bottom inside the power generation box 1. Among them, the right mounting bracket 13 and the left mounting bracket 12 have the same structure and will not be repeated here.
[0037] Optionally, an assembly hole is provided on the fixing plate 16 of the left mounting bracket 12. The rotating shaft of the generator 2 passes through the assembly hole on the fixing plate 16 and is fixedly connected to the input shaft of the gearbox 3 below.
[0038] Optionally, a plurality of arc-shaped limiting blocks 19 are provided on the fixing plate 16 of the left mounting bracket 12. The generator 2 is installed within the arc-shaped limiting blocks 19 to limit the movement of the generator 2. The arc-shaped limiting blocks 19 not only play a role in restricting the displacement of the generator 2, but also can guide maintenance personnel to install and replace the generator 2 at the corresponding position before installation, improving the maintenance and replacement efficiency. Two vertical limiting blocks 20 are spaced apart on the fixing plate 16 of the right mounting bracket 13. The motor 5 is inserted between the two vertical limiting blocks 20 to limit the motor 5 and prevent it from moving. In addition, it can also guide maintenance personnel to install and replace the motor 5 at the corresponding position.
