Description

Technical Field

[0001] The utility model relates to the technical field of fluid machinery, in particular to an intelligent oil-electric hybrid water pump. Background Art

[0002] Traditional water pumps typically rely on a single power source, either electricity or fuel. This results in high energy consumption, poor fuel economy, and non-adjustable pumping flow. Furthermore, these pumps often require manual flow adjustment or water addition during the pumping process, making operation cumbersome and inefficient. While some water pumps with simple control functions have emerged on the market with the advancement of intelligent technology, these products still struggle to meet users' urgent needs for precise pumping flow control, optimized fuel economy, and convenient operation.

[0003] Therefore, it is necessary to develop an intelligent oil-electric hybrid water pump to solve the above problems existing in the prior art. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technologies and provide an intelligent oil-electric hybrid water pump.

[0005] To achieve the above objectives, the present invention provides an intelligent oil-electric hybrid water pump, comprising: a hybrid power controller, an electric drive system and an unpowered water pump, the electric drive system comprising an engine, a forward-stepping generator, a battery, a forward-stepping motor, and a power monitor, the power monitor being used to monitor the power status of the battery, the engine being transmission-connected to the forward-stepping generator, the forward-stepping generator, the battery, and the forward-stepping motor being electrically connected in sequence, and the forward-stepping motor being transmission-connected to the unpowered water pump; the hybrid power controller acquiring real-time status information of the electric drive system, and sending control instructions to the electric drive system based on the acquired real-time status information.

[0006] Furthermore, it also includes a control panel, which is electrically connected to the hybrid power controller. The control panel automatically displays the optimal fuel consumption economy pumping flow value A0 and prompts the user to set a reasonable flow A value. The flow A value satisfies 0<A≤A0.

[0007] Furthermore, in order to speed up the pumping speed, the control panel automatically displays the maximum pumping flow rate A1 value and prompts the user to reasonably set the flow rate A value. The flow rate A value satisfies: A0 <A≤A1

[0008] Further, when the engine operates at the highest thermal efficiency to drive the stepping generator to continuously supply power to the battery, the output power P1 at the output end of the battery and the power generation power P0 of the engine driving the stepping generator at the highest thermal efficiency satisfy P1 > P0. To maximize the provision of the pumping function, the engine directly drives the non-powered water pump, and the control panel automatically displays the maximum pumping flow rate A2 value and prompts the user to reasonably set the flow rate A value, where the flow rate A value satisfies: 0 < A ≤ A2

[0009] Further, when the user sets a reasonable flow rate A value, the flow rate A value satisfies 0 < A ≤ A0, and at this time it is a stable pumping flow rate. The engine operates at the highest thermal efficiency to drive the stepping generator to supply power to the battery. The output power P1 at the output end of the battery and the power generation power P0 of the engine driving the stepping generator at the highest thermal efficiency satisfy P1 ≤ P0. At this time, power is supplied from the battery to the stepping motor via the hybrid controller to drive the non-powered water pump. By the hybrid controller, the engine is kept operating at the highest thermal efficiency to drive the stepping generator to continuously supply power to the battery. By automatically adjusting the working power of the stepping motor and satisfying P1 = P0, the water flow is stable, and the optimal fuel consumption economy pumping flow rate value A0 is automatically measured. At this time, it is prompted that the fuel economy is the highest when the user sets 0 < A ≤ A0. On the premise of maintaining the battery power at 20 - 30% all day long, the engine is cyclically operated at the highest thermal efficiency to drive the stepping generator to ensure the best fuel economy in the user-set flow rate range.

[0010] Further, when the user sets the flow rate A value, the flow rate A value satisfies A0 < A ≤ A1, and at this time the output power P1 at the output end of the battery and the power generation power P0 of the engine driving the stepping generator at the highest thermal efficiency satisfy P1 > P0. The hybrid controller issues an instruction to make the engine directly drive the non-powered water pump, and at this time the stepping generator and the stepping motor stop working. An instruction is sent to the engine through the hybrid controller to automatically adjust the stable pumping flow rate, and the maximum flow rate A1 value is measured by automatically adjusting the throttle to the maximum. At this time, it is prompted that the user sets 0 < A ≤ A1.

[0011] Further, when the user sets the flow rate A value, the flow rate A value satisfies 0 < A ≤ A2, and at this time the stepping generator and the stepping motor stop working. The hybrid controller issues an instruction to make the engine directly drive the non-powered water pump, and the maximum flow rate A2 value is measured by automatically adjusting the throttle to the maximum. At this time, it is prompted that the user sets 0 < A ≤ A2.

[0012] Furthermore, the forward-stepping motor can be connected to an external power grid to directly drive the unpowered water pump. At this time, the maximum output power P2 of the engine and the maximum power P3 of the forward-stepping motor satisfy P2≤P3. The hybrid power controller automatically measures the maximum water outlet flow Amax, and prompts the user to set 0<A≤Amax.

[0013] Furthermore, in order to facilitate adding water to the water suction pipe of the unpowered water pump, the intelligent oil-electric hybrid water pump also includes a small electric water pump, which is arranged at the end of the water suction port of the unpowered water pump.

[0014] Furthermore, the battery is further provided with an external discharge module, and the external discharge module is provided with a socket, and the battery supplies power to other external devices through the socket.

[0015] Advantages of this utility model: This utility model provides an intelligent hybrid water pump. By integrating a hybrid controller with an electric drive system, it significantly enhances the pump's intelligence, enabling precise control of water flow and optimized fuel economy while enhancing operational convenience. Furthermore, the ability to connect the forward-stepping motor to an external power grid broadens its application range, while the inclusion of a small electric water pump further improves pumping efficiency. Overall, this utility model brings significant technological innovation and advancement to the water pump industry. BRIEF DESCRIPTION OF THE DRAWINGS
