Description

Technical Field

[0001] This utility model relates to the field of hybrid vehicle technology, and more particularly to a hybrid vehicle. Background Technology

[0002] As a crucial component of fracturing equipment, the mixing truck continuously mixes and pressurizes fracturing fluids before delivering them to downstream equipment. It offers advantages such as ease of use and immediate injection, leading to its widespread application in oil and gas field production enhancement. Existing mixing trucks typically use diesel engines as their power source, employing mechanical and hydraulic transmissions for transport and operation. Diesel engines suffer from poor fuel economy, significant air and noise pollution, low transmission efficiency, and high maintenance costs.

[0003] In recent years, the petroleum equipment industry has widely carried out research and development of electric fracturing equipment to adapt to the trend of green and environmentally friendly development. To meet the requirements of construction, electric fracturing equipment needs to be connected to the power grid, but most well sites are far from towns and cities, facing problems such as lack of supporting facilities and limited power supply. Therefore, in order to improve the above situation, we propose a hybrid vehicle. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art and provide a hybrid vehicle.

[0005] The technical solution of this utility model is:

[0006] A hybrid vehicle includes a mixing tank and a chassis. The chassis includes a chassis and multiple wheels. The mixing tank is located above the rear of the chassis. A driver's cab is located at the front of the chassis. The vehicle also includes a power supply system, a hydraulic station, a control center, and a working mechanism installed on the chassis. The power supply system is responsible for supplying power to all electrical appliances in the vehicle. The hydraulic station drives the working mechanism. The control center controls the working mechanism and displays various data of the working process.

[0007] To carry and provide power, the chassis is equipped with an engine, a gearbox, and an AC permanent magnet synchronous motor. The AC permanent magnet synchronous motor and the engine are connected in parallel and work together to output power to the gearbox. The gearbox drives multiple wheels to rotate to achieve the movement of the whole vehicle. The engine does not carry any other loads and is only responsible for transmitting power to the gearbox. The gearbox has a power take-off port to output power to the hydraulic station.

[0008] To ensure the stable and efficient operation of the vehicle, the power supply system includes a hydrogen fuel cell system, a power battery, and a power management module. The hydrogen fuel cell system includes a gas source system, a hydrogen fuel cell stack, and a water and thermal management system. The power battery is a commonly used automotive power battery. The input and output terminals of the power battery are electrically connected to the power management module and are charged and discharged as needed. The power management module regulates the gas source system and the water and thermal management system according to the status of the hydrogen fuel cell system, the power battery, and the load to ensure the stable and efficient operation of the hydrogen fuel cell stack.

[0009] To ensure the normal operation of the hydrogen fuel cell stack, the gas supply system provides the necessary hydrogen and oxygen to the stack, enabling it to generate direct current. The gas supply system includes a hydrogen supply system and an air supply system. The hydrogen supply system is connected to a hydrogen storage tank, and the hydrogen in the tank is processed by the hydrogen supply system before entering the anode of the fuel cell stack. The air supply system draws in air from the atmosphere and supplies it to the cathode of the stack. Both the hydrogen supply system and the air supply system are electrically connected to the power management module.

[0010] To maintain the temperature of the hydrogen fuel cell stack within a suitable range, the hydrothermal management system is electrically connected to the power management module. The hydrothermal management system includes a radiator, a heater, a thermostat, and a water pump. The hydrothermal management system exchanges heat with the hydrogen fuel cell stack through coolant.

[0011] To be compatible with grid connection, the power management module can be connected to an external power source, and all the required power can be provided by the external power source alone.

[0012] To facilitate the driving of the working mechanisms, the hydraulic station includes a transfer case and a hydraulic pump. The transfer case is connected to the gearbox via a coupling, thereby driving the hydraulic pump to drive the various working mechanisms.

[0013] To efficiently complete various operations, the operating mechanism includes a dry addition system, an intake manifold, and an exhaust manifold. The dry addition system is mounted on the chassis and located in front of the mixing tank, while the intake manifold and exhaust manifold are arranged on both sides of the dry addition system.

[0014] The present invention adopts the above structure and has the following advantages:

[0015] 1. It adopts a hybrid power system of hydrogen fuel cell and diesel engine, and uses the same hydraulic system as traditional hybrid vehicles as the transmission method, which has the advantages of wide application range, low modification difficulty and compact structure;

[0016] 2. Hydrogen fuel cells generate electricity through electrochemical reactions. They operate without pollution and with low noise, effectively reducing vehicle energy consumption and emissions, and achieving clean energy substitution in the blending process. Attached Figure Description

[0021] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0022] like Figure 1 and Figure 2 As shown, a hybrid vehicle includes a mixing tank 7 and a chassis. The chassis includes a chassis and multiple wheels. The mixing tank 7 is located above the rear of the chassis. A cab 1 is located at the front of the chassis, where the operator can control the vehicle by accelerating, braking, and steering. The hybrid vehicle also includes a power supply system, a hydraulic station 14, a control center 10, and a working mechanism installed on the chassis. The chassis is equipped with an engine, a gearbox 8, and an AC permanent magnet synchronous motor. The AC permanent magnet synchronous motor and the engine are connected in parallel and jointly output power to the gearbox 8. The gearbox 8 drives multiple wheels to rotate, thus moving the entire vehicle. The engine does not carry any other loads and is only responsible for transmitting power to the gearbox 8. The gearbox 8 has a power take-off port, which is connected to the hydraulic station 14 through a coupling to output power to the hydraulic station 14, thereby driving the working mechanism to complete the mixing operation.

[0023] The power supply system is responsible for supplying power to all electrical appliances in the vehicle and completely replaces the function of the traditional 12V battery in a car, reducing the burden on the engine.

[0024] The hydraulic station 14 is installed between the gearbox 8 and the hydrogen fuel cell system 3. The hydraulic station 14 includes a transfer case and a hydraulic pump. The transfer case is connected to the gearbox 8 through a coupling, thereby driving the hydraulic pump to drive the various working mechanisms to work.

[0025] like Figure 3 As shown, the control center 10 controls the operating mechanism and displays various data of the operating process;

[0026] The power supply system includes a hydrogen fuel cell system 3, a power battery 13, and a power management module 9. The hydrogen fuel cell system 3 includes a gas source system, a hydrogen fuel cell stack, and a water and heat management system. The power battery 13 is a commonly used vehicle power battery 13. The input and output terminals of the power battery 13 are electrically connected to the power management module 9 and are charged and discharged as needed. The power management module 9 regulates the gas source system and the water and heat management system according to the status of the hydrogen fuel cell system 3, the power battery 13, and the load to ensure the stable and efficient operation of the hydrogen fuel cell stack. The power management module 9 can be connected to an external power source and is equipped with a power interface, which can be connected to the power grid for pure electric drive.

[0027] The gas supply system provides the necessary hydrogen and oxygen to the hydrogen fuel cell stack, enabling the stack to generate direct current. The gas supply system includes a hydrogen supply system and an air supply system. The hydrogen supply system is connected to a hydrogen storage tank 2. Hydrogen from the storage tank 2, after being processed by the hydrogen supply system, enters the anode of the hydrogen fuel cell stack at a specific flow rate, pressure, temperature, and humidity. The air supply system draws air from the atmosphere and supplies it to the cathode of the hydrogen fuel cell stack at a specific flow rate, pressure, temperature, and humidity. Both the hydrogen supply system and the air supply system are electrically connected to the power management module 9, which transmits flow rate, pressure, temperature, and humidity information to the power management module 9 for power supply and regulation. When starting the hydrogen fuel cell stack, the power management module 9 draws power from the power battery 13 to perform the startup operation.

[0028] The hydrothermal management system is electrically connected to the power supply management module 9. The hydrothermal management system includes a radiator 4, a heater, a thermostat, and a water pump. The hydrothermal management system exchanges heat with the hydrogen fuel cell stack through coolant to maintain the temperature of the hydrogen fuel cell stack within a suitable range.

[0029] The working mechanism includes a dry mixing system 5, an intake manifold 11, and an exhaust manifold 12. The dry mixing system 5 is mounted on the chassis and located in front of the mixing tank 7. The intake manifold 11 and the exhaust manifold 12 are arranged on both sides of the dry mixing system 5, with the intake manifold 11 located on the passenger side and the exhaust manifold 12 located on the driver side. The dry mixing system 5 is equipped with an auger drive motor. The intake manifold 11 is equipped with an intake centrifugal pump drive motor. The exhaust manifold 12 is equipped with an exhaust centrifugal pump drive motor. The mixing tank 7 is equipped with an agitator drive motor 6. All of the aforementioned motors are connected to the hydraulic station 14 via oil pipes.

[0030] During startup, the power management module 9 calls the power battery 13 to start the hydrogen fuel cell stack until the hydrogen fuel cell stack can output power stably. When the load is low, the hydrogen fuel cell system 3 charges the power battery 13 to maintain a certain amount of stored power. When the load changes suddenly or there are power fluctuations, because the dynamic response of the hydrogen fuel cell is slow, the power battery 13 assists the hydrogen fuel cell system 3 in supplying power to the motor to provide a stable and sufficient power supply.

[0031] Specifically, the power consumption strategy of the power battery 13 is as follows: when the hydrogen fuel cell system 3 is in a shutdown state, the power battery 13 performs the start-up action or serves as a temporary power source; secondly, because the dynamic response of the hydrogen fuel cell stack is slow, it cannot provide sufficient power in time when the load changes, so the power battery 13 discharges to meet the load requirements; the power supply management module 9 sets a lower limit for the power battery 13's charge, and when the lower limit is reached, the hydrogen fuel cell stack uses excess power to charge the power battery 13 to meet the subsequent usage needs of the power battery 13;

[0032] The power management module 9 integrates the electrical energy from the hydrogen fuel cell system 3 and the power battery 13 and outputs it to the AC permanent magnet synchronous motor and all electrical appliances in the vehicle. It also adjusts the power consumption strategy in real time according to the status of the hydrogen fuel cell system 3, the power battery 13 and the load to ensure a sufficient and stable power supply. The power management module 9 is also equipped with a power interface, which can be connected to the power grid for pure electric drive.

[0033] It should be noted that the mixing process mentioned above is an application of existing technology.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0035] All equivalent changes and modifications made to the scope of this utility model patent application shall fall within the technical scope of this utility model.
