Description

Technical Field

[0001] The present invention relates to the technical field of fluid machinery, in particular to an oil-electric-water hybrid power water pump which integrates an unpowered water pump, electric drive, hydroelectric power generation, gasoline generator power supplementation and modular design. Background Art

[0002] In the field of fluid machinery technology, water pumps, as key equipment, are widely used in agricultural irrigation, urban water supply, drainage systems, industrial cooling and other fields. Traditional water pumps usually rely on a single form of energy, such as electricity or fuel engines, which to some extent limits their energy efficiency, environmental adaptability and operational flexibility.

[0003] Although electric-driven water pumps are energy-saving and environmentally friendly, their operation is limited in areas with unstable power supply or in remote areas. Although fuel-driven water pumps can provide stable power, they consume a lot of fuel, have high operating costs, and emit exhaust gas that pollutes the environment.

[0004] In recent years, with the continuous advancement of energy technology and the enhancement of environmental awareness, people have begun to explore the combination of multiple energy forms to improve the energy efficiency and environmental adaptability of water pumps. For example, some hybrid water pumps combine two power sources, electricity and fuel engines, and switch working modes according to actual needs. However, this type of water pump has a complex structure, high cost, and fails to make full use of natural energy.

[0005] In addition, most existing water pumps are fixed in design, which makes it difficult to flexibly adjust according to the water flow rate and work requirements. In an environment where the water flow rate varies greatly, the working efficiency of the water pump is often low and it is easy to waste energy.

[0006] Therefore, developing a water pump that can automatically adjust the working mode according to different water flow speeds has become an urgent problem to be solved in the current field of fluid machinery technology. Summary of the invention

[0007] In order to solve the problems existing in the prior art, the present invention proposes a modular oil-electric-water hybrid power water pump, which is characterized by combining the natural pumping capacity of the unpowered water pump, the flexible adjustment of the electric telescopic rod, the energy recovery of the synchronous generator and the auxiliary drive of the asynchronous motor, so as to realize automatic adjustment of the working mode according to different water flow speeds and improve energy utilization efficiency. At the same time, the gasoline generator is used to supplement electricity for pumping water, expanding the application scenarios of the water pump.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A modular oil-electric-water hybrid water pump, comprising an unpowered water pump;

[0010] The power sources of the front and rear ends of the central rotating shaft of the unpowered water pump are automatically selected and connected to the first power fan blade and the asynchronous motor power through the second and third electric telescopic rods and the transmission shaft, and two groups of pumping fan blades are arranged in the pumping chamber of the unpowered water pump;

[0011] The unpowered water pump is equipped with a PLC controller, an asynchronous motor, a synchronous generator, three electric telescopic rods and a battery pack. A flow control switch connected to the PLC controller is provided at the water outlet at the bottom of the unpowered water pump; the first power fan blade is directly connected to the front end of the central rotating shaft of the unpowered water pump through the third electric telescopic rod and the transmission shaft as a source of water pumping power; the asynchronous motor is directly connected to the rear end of the central rotating shaft of the unpowered water pump through the second electric telescopic rod and the transmission shaft as a source of water pumping power; the asynchronous motor is directly connected to the first power fan blade through the second and third electric telescopic rods and the transmission shaft, and is electrically connected to the battery pack as a participant in the charging function; the forward-stepping motor is directly connected to the first and second power fan blades through the first and third electric telescopic rods and the transmission shaft, and is electrically connected to the battery pack as a participant in the charging function; the synchronous generator is connected to the second power fan blade through the first electric telescopic rod and the transmission shaft, and is electrically connected to the battery pack, which only participates in the charging function and does not serve as a water pump power source;

[0012] The asynchronous motor, the synchronous generator, the battery pack, the three electric telescopic rods are connected to the PLC controller;

[0013] The unpowered water pump is also equipped with a gasoline generator, which is connected to a PLC controller and assists in pumping water with the asynchronous motor.

[0014] Furthermore, the PLC controller is also connected to a user interface, which includes a display screen and input buttons for setting and displaying the working parameters, status information and fault alarms of the water pump; the PLC controller has an internal networked remote control device, which can set the pumping flow value on the mobile phone according to the user's ideas, or stop pumping and hydropower generation.

[0015] Furthermore, the unpowered water pump, synchronous generator, and asynchronous motor are all modularly designed, and the modules are connected through standard interfaces and can be independently replaced or upgraded to adapt to different working environments and requirements.

[0016] Furthermore, the direction of river water flow is from the first power fan blade to the second power fan blade.

[0017] Furthermore, gasoline generators can be used to supplement electricity for water pumping, expanding the application scenarios of water pumps.

[0018] Regarding the drawings in the specification Figure 2The oil-electric-water hybrid pump has specific operation logic of internal components according to different scenarios:

[0019] Remark:

[0020] (1) The synchronous generator gear and the electric telescopic rod 1 have a matching gear rod, which can be movable;

[0021] (2) The asynchronous motor gear matches the electric telescopic rod 2, and the gear rod is movable;

[0022] (3) The gear connecting the power fan blade 1 and the electric telescopic rod 3 are matched with each other, but they are movable;

[0023] (4) The gear connecting the power blade 2 and the electric telescopic rod 1 are matched with the wheel rod, which can be mobile;

[0024] The gear distance of the unpowered water pump is now set as K value, and the rated water flow rate is set as A value

[0025] 1. Operation of the electric telescopic pole without mains electricity or gasoline generator

[0026] (1) High-speed water flow: When the water outlet flow rate is greater than or equal to value A, the three electric telescopic rods are not activated. If the water outlet flow rate is kept around value A, the synchronous generator and the asynchronous generator will generate electricity together and supply power to the battery pack. When the power is at 95%, the power will be supplied to the grid.

[0027] (2) Medium-speed water flow: When O < water flow < A value, the three electric telescopic rods are not started. The synchronous generator supplies power to the battery, and the battery drives the asynchronous motor to form a parallel mode with the power fan 1 to pump water.

[0028] (3) Low-speed water flow: When the outlet flow rate is less than 0. The electric telescopic rod 1 is not started, the electric telescopic rod 3 is pushed to the right by k / 4, and the electric telescopic rod 2 is pushed to the left by k / 4. The gears are matched, and the asynchronous motor uses the power fan blade 1 to directly generate electricity, and together with the synchronous generator, it supplies power to the battery. When the power reaches 95%, the electric telescopic rod 1 is not started, the electric telescopic rod 3 is pulled to the left by k / 2, and the electric telescopic rod 2 is pulled to the right by k / 4. At this time, the dynamic fan blades 1 and 2 jointly drive the synchronous generator to generate electricity, and the asynchronous motor uses the battery to directly pump water. When the power is less than 30%, pumping stops and power generation continues until the power is full of 95%.

[0029] (4) If water is not pumped, the power grid is powered: the electric telescopic rod 1 is not started, the electric telescopic rod 3 is pushed to the right by k / 4, the electric telescopic rod 2 is pushed to the left by k / 4, and the asynchronous motor and the synchronous generator generate electricity together.

[0030] 2. Operation of the electric telescopic pole with mains power and gasoline generator

[0031] (1) High-speed water flow, medium-speed water flow, mains or gasoline generator is not transmitting power, and the three electric telescopic rods are not started. In the absence of mains or gasoline generator, the system automatically maintains the pumping water flow rate A value.

[0032] (2) Low-speed water flow, in the absence of mains electricity and gasoline generators, there is a periodic pumping situation. The electric telescopic rod 1 is not started, the electric telescopic rod 3 is pushed to the right by k / 4, and the electric telescopic rod 2 is pushed to the left by k / 4. The gears are matched, and the asynchronous motor uses the power fan blade 1 to directly generate electricity, and together with the synchronous generator, it supplies power to the battery. Before the battery power is less than 95%, the external power supply directly drives the guide motor to pump water, stabilizing the water flow value A. After the battery power reaches 95%, the external power supply is cut off, the electric telescopic rod 1 is not started, the electric telescopic rod 3 is pulled to the left by k / 2, and the electric telescopic rod 2 is pulled to the right by k / 4. At this time, the first and second power fans jointly drive the synchronous generator to generate electricity through the electric telescopic rod 1, and the asynchronous motor uses the battery to directly pump water. Until the battery power is less than 30%, the external power supply is directly connected, and the synchronous generator continues to generate electricity.

[0033] (3) If water is not pumped, the mains or gasoline engine stops transmitting electricity, and the electricity is supplied to the grid. The electric telescopic rod 1 is not started, the third electric telescopic rod is pushed to the right by k / 4, and the second electric telescopic rod is pushed to the left by k / 4. The asynchronous motor uses the first power fan blade to directly generate electricity, and supplies power to the grid together with the synchronous generator.

[0034] (4) The power fan blades, battery pack, synchronous generator, and electric telescopic rod can be removed, and the power is transmitted by the mains or gasoline generator. The asynchronous motor and the unpowered water pump 10 are relied on to stabilize the water flow value>A (there is water but no water flow).

[0035] Beneficial effects of the present invention:

[0036] 1. High efficiency and energy saving: Automatically adjust the working mode according to the water flow speed, maximize the use of natural energy and electrical energy, and reduce energy consumption.

[0037] 2. Environmentally friendly: Reduce dependence on traditional energy and reduce carbon emissions through hydropower generation.

[0038] 3. Intelligent control: PLC controller realizes precise control and improves system stability and reliability.

[0039] 4. Flexible application: Modular design makes it easy to adapt to different scenario requirements and is easy to maintain and upgrade. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] Example:

[0049] The modular oil-electric-water hybrid power water pump of the present invention comprises:

[0050] The power source of the unpowered water pump 10 is automatically selected to be connected to the power of the first power fan blade 20 and the asynchronous motor 40 through the second electric telescopic rod B, the third electric telescopic rod C and the transmission shaft transmission connection. Two sets of pumping fan blades are arranged in the pumping chamber of the unpowered water pump;

[0051] The unpowered water pump 10 is equipped with a PLC controller 30, an asynchronous motor 40, a synchronous generator 50 and a battery pack 60. A flow control switch 12 connected to the PLC controller 30 is provided at the water outlet 11 at the bottom of the unpowered water pump 10; the asynchronous motor 40 is connected to the transmission shaft of the second electric telescopic rod B and is connected to the battery pack 60; the synchronous generator 50 is connected to the second power fan blade 21 through the first electric telescopic rod A and the transmission shaft, and is electrically connected to the battery pack 60, that is, the second power fan blade 21 can only drive the synchronous generator 50 to generate electricity exclusively, and does not involve direct driving of the unpowered water pump 10; the first power fan blade 20 is connected to the front end gear of the unpowered water pump 10 through the third electric telescopic rod C and the transmission shaft, that is, the first power fan blade 20 can directly drive the unpowered water pump 10. According to different water flow rates, the asynchronous motor 40 can automatically switch the output power source or power generation mode, and the battery plays the charging and discharging function of the asynchronous motor and the forward-stepping generator;

[0052] The asynchronous motor 40, the synchronous generator 50, the battery pack 60, and the electric telescopic rods (A, B, C) are all connected to the PLC controller 30;

[0053] The unpowered water pump 10 is also equipped with a gasoline generator 80 , which is connected to the PLC controller 30 and is used together with the asynchronous motor 40 to assist in pumping water.

[0054] As a further improvement of this scheme,

[0055] The PLC controller is also connected to a user interface, which includes a display screen and input buttons for setting and displaying the working parameters, status information and fault alarms of the water pump. The PLC controller has an internal networked remote control device, which can set the pumping flow value or stop pumping on the mobile phone according to the user's ideas, and the hydropower generation power supply network.

[0056] The unpowered water pump, synchronous generator, asynchronous motor and electric telescopic rod are all modularly designed. The modules are connected through standard interfaces and can be replaced or upgraded independently to adapt to different working environments and needs.

[0057] The direction of river water flow is from the first power fan blade to the second power fan blade.

[0058] Working Mode:

[0059] Set the minimum value of the outlet flow control switch parameter to A

[0060] 1. No electricity or gasoline generator

[0061] (1) High-speed water flow: the first power blade 20 directly drives (direct drive mode) the shaft of the non-powered water pump 10 through the electric telescopic rod C; the second power blade 21 directly drives the synchronous generator 50 through the electric telescopic rod A to generate electricity for the battery pack 60. At this time, the water outlet flow rate is greater than the A value, and the battery pack 60 powers the asynchronous motor 40, forming a parallel mode with the first power blade 20, driving the gears of the non-powered water pump 10 to pump water. At this time, the water outlet flow rate is much greater than the A value. If you want to keep the water outlet flow rate around the A value, the asynchronous motor 40 uses the gears of the second electric telescopic rod B and the third electric telescopic rod C to connect to make the first power blade 20 participate in power generation, and the battery pack 60 is powered by the mains at 95%; when pumping stops, the asynchronous motor 40 and the synchronous generator 50 participate in powering the mains;

[0062] (2) Medium-speed water flow: the first power blade 20 directly drives the shaft of the non-powered water pump 10 through the electric telescopic rod C. At this time, 0 < water outlet flow < A value, the second power blade 21 uses the synchronous generator 50 to generate electricity for the battery pack 60, and the battery pack 60 forms a parallel mode with the first power blade 20 through the asynchronous motor 40 to keep the water outlet flow around A value; when pumping stops, the asynchronous motor 40 and the synchronous generator 50 participate in power supply, and the power supply is from the city power.

[0063] (3) Low-speed water flow, the first power blade 20 directly drives the shaft of the non-powered water pump 10 through the electric telescopic rod C. At this time, the water outlet flow rate is less than 0, the first power blade 20 stops pumping water, and drives the asynchronous motor 40 to generate electricity through the transmission shaft transmission connection of the second electric telescopic rod B and the third electric telescopic rod C. At the same time, the second power blade 21 continues to drive the synchronous generator 50 to generate electricity; when the battery pack is fully charged to 95%, the first power blade 20 drives the synchronous generator 50 to generate electricity in the battery pack 60 through the transmission shaft transmission connection of the first electric telescopic rod A and the third electric telescopic rod C, and the second power blade 21. The battery pack 60 supplies power to the asynchronous motor 40, and the asynchronous motor 40 directly drives the non-powered water pump 10 to form a series mode to keep the water outlet flow rate around the value A; when the power is less than 30%, stop pumping water and continue to generate electricity until the power is fully charged to 95%. Stop pumping water, and the asynchronous motor 40 and the synchronous generator 50 participate in power generation to supply city power.

[0064] (4) Stop pumping, and the asynchronous motor 40 and the synchronous generator 50 will generate electricity to supply the city electricity. Specific operation principle: The first power fan blade 20 uses the transmission shaft of the second electric telescopic rod B and the third electric telescopic rod C to drive the asynchronous motor 40 to generate electricity. At the same time, the second power fan blade 21 continues to drive the synchronous generator 50 to generate electricity.

[0065] 2. When there is city electricity and gasoline generator

[0066] (1) High-speed water flow, medium-speed water flow, the mains or gasoline generator stops transmitting electricity. The PLC controller 30 uses the water flow rate to autonomously adjust the working state of the three electric telescopic rods to maintain the water flow value A; pumping stops, and the asynchronous motor 40 and the synchronous generator 50 participate in power generation to supply the mains.

[0067] (2) Low-speed water conservancy: in the absence of mains electricity and gasoline generators, during the periodic charging time, the mains electricity or gasoline generator 80 directly acts on the asynchronous motor 40 to drive the unpowered water pump 10; at this time, the first power fan 20 drives the synchronous generator 50 to generate electricity through the first electric telescopic rod A and the third electric telescopic rod C transmission shaft transmission connection and the second power fan 21. When the battery pack 60 is fully charged to 95%, the mains electricity and gasoline generator 80 stop supplying power, and the battery pack 60 continues to supply power to the asynchronous motor 40. The asynchronous motor 40 drives the unpowered water pump 10 through the second electric telescopic rod B to keep the outlet flow rate at about value A; pumping stops, and the asynchronous motor 40 and the synchronous generator 50 participate in power generation to supply mains electricity.

[0068] (3) The power fan blades, battery pack 80, synchronous generator 50, and electric telescopic rod can be removed, and the mains or gasoline generator 80 transmits power. The asynchronous motor 40 and the unpowered water pump 10 are used to stabilize the water flow value>A (there is water but no water flow).

[0069] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
