[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] like Figure 1 An intelligent multi-power system shown includes an engine 1, a generator set 2, a heater set, and a fuel tank set 4.

[0037] in:

[0038] The engine 1 is used to drive the vehicle to travel and rise and fall, and the generator set 2 is used to drive the action of the actuator on the vehicle; the oil inlet and outlet of the engine 1 and the generator set 2 are connected to the fuel tank group; the heater group is connected to the cooling water cylinder body of the engine 1 and the generator set 2, and is used to heat the cooling water of the engine 1 and the generator set 2.

[0039] In this embodiment: the heater group includes a first heater 30 and a second heater 31. The first heater 30 is connected to the cooling water cylinder of the engine 1, and the second heater 31 is connected to the cooling water cylinder of the generator set 2. Since they are used to heat the cooling water of the engine 1 and the generator set 2 respectively, the first heater 30 and the second heater 31 are heaters with different powers. The first heater 30 and the second heater 31 are both fuel heaters, and the first heater 30 and the second heater 31 are both connected to the fuel tank group 4, and the fuel tank group 4 provides fuel for the operation of the first heater 30 and the second heater 31.

[0040] In a preferred implementation manner of the present embodiment: the first heater 30 and the second heater 31 are configured with a water pump and an oil pump. The first heater 30 and the second heater 31 are connected to the cooling water cylinder of the engine 1 and the generator set 2 through the water pump. The first heater 30 and the second heater 31 are connected to the fuel tank group 4 through the oil pump. The water pump and the oil pump can provide sufficient power for the extraction of cooling water and fuel.

[0041] In this embodiment, the fuel tank group 4 adopts a composite fuel tank, which includes a first fuel tank 40 and a second fuel tank 41. The first fuel tank 40 is provided with an oil outlet 400, an oil return port 401 and an exhaust port 402. The oil inlets of the engine 1 and the generator set 2 are connected to the oil outlet 400 of the first fuel tank 40, and the oil outlets of the engine 1 and the generator set 2 are connected to the oil return port 401 of the first fuel tank 40. The second fuel tank 41 is only provided with an oil outlet 410, and the first heater 30 and the second heater 31 are connected to the oil outlet 410 of the second fuel tank 41. Since the second fuel tank 41 provides energy for heating the first heater 30 and the second heater 31, the fuel provided by the second fuel tank 41 will be consumed, and the second fuel tank 41 does not need to be designed with an oil return port.

[0042] In a preferred implementation manner of the present embodiment: the engine 1 and the generator set 2 are respectively connected to a first fuel tank 40, the first heater 30 and the second heater 31 are respectively connected to a second fuel tank 41, that is, the fuel tank group 4 is provided with four fuel tanks, two first fuel tanks 40 and two second fuel tanks 41, each of which is configured with a dedicated fuel tank and does not affect each other.

[0043] The system further includes a heating controller 5, which is used to control the start and stop of the heater group, such as stopping heating when the temperature of the cooling water in the engine 1 and the generator set 2 is heated to a set temperature. Of course, the heating controller 5 can be integrated into the control system of the vehicle.

[0044] like Figure 2The transport vehicle shown includes a frame 60, a lifting suspension 61, a suspension drive component (not shown in the figure), wheels 62, a wheel drive component (not shown in the figure), an actuator 63, and an intelligent multi-power system 64. Among them:

[0045] The lifting suspension 61 is connected to the bottom of the frame 60, the suspension driving component is connected to the lifting suspension 61, and is used to drive the lifting suspension 60 to lift and lower, the wheel 62 is connected to the lifting suspension 61, the wheel driving component is connected to the wheel 62, and is used to drive the wheel to move, the intelligent multi-power system 64 is connected to the bottom of the frame 60, the engine 1 is connected to the suspension driving component and the wheel driving component, and is used to provide power to the suspension driving component and the wheel driving component, and the generator set 2 is connected to the actuator 63, and is used to provide power to the actuator.

[0046] Example:

[0047] Transport vehicle: flatbed truck;

[0048] Engine 1: 368kw Cummins engine;

[0049] Generator set 2: 50kw generator set;

[0050] The first heater 30: 15kw fuel heater;

[0051] The second heater 31: 5kw fuel heater;

[0052] First fuel tank 40: three-way oil float;

[0053] Heating controller 5: arranged in the cab 65;

[0054] Suspension drive components: hydraulic cylinder;

[0055] Wheel drive components: wheel motor;

[0056] Actuator 63: landing gear, the landing gear is arranged on the frame.

[0057] The 368kw Cummins engine is the main power source of the flatbed truck. The engine 1 drives two variable hydraulic pumps 66 to rotate through a coupling. One variable hydraulic pump 66 drives the wheel-side motor to rotate, driving the wheels 62 to rotate, so that the entire vehicle can move; the other variable hydraulic pump 66 drives the lifting and lowering of the suspension cylinder, thereby lifting and lowering the entire flatbed truck; the 50kw generator set is the power source of the landing gear. The generator set 2 drives the lifting and lowering motor to rotate to realize the lifting and lowering of the landing gear.

[0058] When transporting on a flatbed truck in a low temperature environment (-25°~-40°):

[0059] When the engine 1 fails to ignite, the start button of the 15kw fuel heater is pressed, and the water pump of the first heater 30 draws water from the hot water inlet of the engine 1. At the same time, the oil pump of the first heater 30 draws oil from the second fuel tank 41 to burn to heat the cooling water. The heated cooling water enters the cylinder water channel through the cold water inlet of the engine 1. When the water temperature of the cooling water in the engine 1 reaches 80°, it is automatically shut down, and then the engine 1 is ignited and started.

[0060] When the generator set 2 fails to ignite, press the start button of the 5kw fuel heater, the water pump of the second heater 31 draws water from the hot water inlet of the generator set 2, and at the same time the oil pump of the second heater 31 draws oil from the second fuel tank 41 to heat the cooling water, and the heated cooling water enters the cylinder water channel through the cold water inlet of the generator set 2. When the water temperature in the generator set 2 reaches 80°, it automatically shuts down, and then the generator set 2 is ignited and started.

[0061] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
