[0002] The fuel power system of construction machinery has high energy consumption and poor comfort and economy. Electrification or partial electrification has become a development trend.

[0003] At present, the relevant technology generally adopts a conventional fuel engine layout, with an external PTO power take-off connected to a dedicated generator. The dedicated generator stores electrical energy in a battery pack for use by a stirring component, a water washing component, and an external parking air conditioner.

[0004] However, the addition of a PTO to the engine adds related accessories and a transmission chain, which takes up a lot of space, resulting in high engine power system costs and reduced thermal efficiency. Moreover, the dedicated generator has overlapping functions with the engine's own small generator, resulting in functional redundancy. Utility Model Content

[0005] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0006] To this end, a first aspect of an embodiment of the utility model provides a power system.

[0007] A second aspect of the embodiments of the utility model provides a pump truck.

[0009] The power system provided by the embodiment of the utility model includes a pumping component, a driving component, a generator and an energy storage device. Specifically, the driving component is connected to the pumping component, that is, the driving component can drive the pumping component to work.

[0010] The generator is connected to the drive component. It can be understood that under the drive of the drive component, the generator can generate electrical energy. The generator is connected to the energy storage device, and the energy storage device can store electrical energy. That is, the generator can store the generated electrical energy in the energy storage device so that the energy storage device can power the load.

[0011] The load includes the operating system and the on-board electrical components. In other words, the electrical energy generated by the generator is used to power the operating system and the on-board electrical components through the energy storage device.

[0012] It is understandable that in the related art, a pump truck is generally provided with a dedicated generator connected to the engine through a power take-off, and the dedicated generator supplies power to the operating system through a battery pack. The small generator that comes with the engine supplies power to the on-board electrical components through a battery.

[0013] Since the generator is connected to the energy storage device, and the energy storage device is connected to the operating system and the on-board electrical components, that is to say, one generator and one energy storage device are used to power the operating system and the on-board electrical components at the same time, that is, the special generator connected to the power take-off and used to store electrical energy in the battery pack and the small generator of the engine are integrated into one generator. At the same time, the battery pack and battery in the related technology are integrated into one energy storage device, which can significantly reduce the functional redundancy of the power system, improve the structural integration of the power system, and simplify the structure of the power system.

[0014] Moreover, since the generator is connected to the drive assembly, the power take-off in the related technology is eliminated, which effectively solves the problem of the power take-off in the related technology occupying a large space when taking power, reduces the power system-related accessories, power transmission chain and control program, reduces the layout space, reduces the manufacturing cost of the pump truck, improves the transmission efficiency, reduces energy consumption, and thus effectively improves the thermal efficiency of the pump truck.

Even if the pump truck is waiting for materials and the engine stops working, the air-conditioning device can still run to adjust the temperature in the cab, thereby eliminating or reducing the use of an external parking air-conditioner in the related technology. That is, by using an air-conditioning device with an electric compressor, the air-conditioning device of the pump truck can work in any state, which solves the problem of affecting the cab layout due to the external parking air-conditioner and reduces the manufacturing cost of the pump truck.

[0021] Moreover, since the air-conditioning compressor in the related technology is replaced with an electric compressor, the transmission structure used to drive the air-conditioning compressor in the related technology can be eliminated, the transmission structure of the power system can be optimized, and the structure of the power system can be simplified, the transmission efficiency can be improved, and the manufacturing cost of the pump truck can be reduced.

And the generator can generate electrical energy. It can be understood that the electrical energy generated by the generator can be stored in the energy storage device to power the load.

[0032] Since the air-conditioning compressor in the related technology is replaced with an electric compressor, the step idler wheel connected to the generator and the belt connected to the step idler wheel and the air-conditioning compressor in the related technology are eliminated, thereby further reducing the related accessories, power transmission chain and control program of the power system, optimizing the transmission structure of the power system, thereby improving the transmission efficiency, reducing the manufacturing cost of the pump truck, reducing energy consumption, and effectively improving the thermal efficiency of the pump truck.

[0058] The power system 100 provided in the embodiment of the utility model includes a pumping component 110, a driving component 120, a generator 130 and an energy storage device 140. Specifically, the driving component 120 is connected to the pumping component 110, that is, the driving component 120 can drive the pumping component 110 to work.

[0059] The generator 130 is connected to the drive component 120. It can be understood that, under the drive of the drive component 120, the generator 130 can generate electrical energy. The generator 130 is connected to the energy storage device 140, and the energy storage device 140 can store electrical energy. That is to say, the generator 130 can store the generated electrical energy in the energy storage device 140 so that the energy storage device 140 can power the load 180.

[0060] The load 180 includes an operating system 170 and an onboard electrical component 190. That is, the electrical energy generated by the generator 130 is used to power the operating system 170 and the onboard electrical component 190 through the energy storage device 140.

[0061] It is understandable that in the related art, a pump truck is generally provided with a dedicated generator connected to the engine through a power take-off, and the dedicated generator supplies power to the operating system through a battery pack. The small generator that comes with the engine supplies power to the on-board electrical components through a battery.

[0062] Since the generator 130 is connected to the energy storage device 140, and the energy storage device 140 is connected to the operating system 170 and the on-board electrical components 190, that is to say, one generator 130 and one energy storage device 140 are used to power the operating system 170 and the on-board electrical components 190 at the same time, that is, the dedicated generator connected to the power take-off and used to store electrical energy in the battery pack and the small generator of the engine are integrated into a generator 130 in the related technology, and at the same time, the battery pack and the battery in the related technology are integrated into an energy storage device 140, thereby significantly reducing the functional redundancy of the power system 100, improving the structural integration of the power system 100, and simplifying the structure of the power system 100.

[0063] Moreover, since the generator 130 is connected to the drive assembly 120, the power take-off in the related art is eliminated, which effectively solves the problem of the power take-off in the related art occupying a large space when taking power, reduces the related accessories, power transmission chain and control program of the power system 100, reduces the layout space, reduces the manufacturing cost of the pump truck, improves the transmission efficiency, reduces energy consumption, and thus effectively improves the thermal efficiency of the pump truck.

[0066] The air conditioning compressor in the related art is generally connected to the engine through a belt, that is, when the pump truck is waiting for material, that is, when the engine stops working, the air conditioning compressor also stops working. Generally, an additional parking air conditioner is required to start when the pump truck is waiting for material.

[0067] The air conditioning device 150 includes an electric compressor 151, which is specifically connected to the energy storage device 140. That is, the energy storage device 140 supplies power to the electric compressor 151, so that when the pump truck is waiting for material, the electric compressor 151 can still work due to the power supply of the energy storage device 140.

[0068] That is, the air-conditioning compressor in the related art is replaced with an electric compressor 151. Even if the pump truck is waiting for materials and the engine 121 stops working, the air-conditioning device 150 can still run to adjust the temperature in the cab, thereby eliminating or reducing the use of an external parking air-conditioner in the related art. That is, by using an air-conditioning device 150 with an electric compressor 151, the air-conditioning device 150 of the pump truck can work in any state, which solves the problem of affecting the cab layout due to the external parking air-conditioner and reduces the manufacturing cost of the pump truck.

[0069] Moreover, since the air-conditioning compressor in the related technology is replaced with an electric compressor 151, the transmission structure in the related technology used to drive the air-conditioning compressor can be eliminated, the transmission structure of the power system 100 can be optimized, and the structure of the power system 100 can be simplified, the transmission efficiency can be improved, and the manufacturing cost of the pump truck can be reduced.

[0073] Since the generator 130 is connected to the energy storage device 140, and the energy storage device 140 is connected to the operating system 170 and the on-board electrical components 190, that is to say, one generator 130 and one energy storage device 140 are used to power the operating system 170 and the on-board electrical components 190 at the same time, that is, the dedicated generator connected to the power take-off and used to store electrical energy in the battery pack and the small generator of the engine are integrated into a generator 130 in the related technology, and at the same time, the battery pack and the battery in the related technology are integrated into an energy storage device 140, thereby significantly reducing the functional redundancy of the power system 100, improving the structural integration of the power system 100, and simplifying the structure of the power system 100.

[0074] Moreover, since the generator 130 is connected to the drive assembly 120, the power take-off in the related art is eliminated, which effectively solves the problem of the power take-off in the related art occupying a large space when taking power, reduces the related accessories, power transmission chain and control program of the power system 100, reduces the layout space, reduces the manufacturing cost of the pump truck, improves the transmission efficiency, reduces energy consumption, and thus effectively improves the thermal efficiency of the pump truck.

The generator 130 can generate electrical energy. It is understood that the electrical energy generated by the generator 130 can be stored in the energy storage device 140 to power the load 180.

[0080] Since the air-conditioning compressor in the related art is replaced with an electric compressor 151, the step idler wheel connected to the generator and the belt connected to the step idler wheel and the air-conditioning compressor in the related art are eliminated, thereby further reducing the related accessories, power transmission chain and control program of the power system 100, optimizing the transmission structure of the power system 100, thereby improving the transmission efficiency, reducing the manufacturing cost of the pump truck, reducing energy consumption, and effectively improving the thermal efficiency of the pump truck.

[0089] Specifically, the engine 121 is a fuel engine. When the fuel engine is working, the fuel combustion drives the piston to move. The piston is connected to the connecting rod, thereby driving the crankshaft to rotate through the connecting rod. Under the action of the idler pulley 220 and the first tensioning pulley 210, the first belt 1222 drives the generator 130 and the pumping assembly 110 to work. Under the action of the second tensioning pulley 230, the second belt 1223 drives the fan pulley 161 to work, thereby driving the fan to work and generate airflow.
