DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present application and, in conjunction with the accompanying drawings, further description of the technical solutions of the present application is provided, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided solely to assist in a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, for clarity and brevity, descriptions of known functions and configurations have been omitted.

[0031] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0032] Drainage equipment can be hydraulically driven. However, the heat dissipation design of the engine and hydraulic system of some drainage equipment is not perfect. On the one hand, the engine and hydraulic system need to dissipate heat independently, and the heat dissipation design still has room for improvement. On the other hand, the engine's rain protection is poor. To this end, the present embodiment provides a power system for mobile drainage equipment that can be used to improve the above-mentioned problems. The power system provided in the present embodiment is described in detail below with reference to the accompanying drawings.

[0033] refer to Figures 1-4 The power system includes a housing 10, an engine 20, a hydraulic pump 30, a radiator 40, and a cooling fan 50. The housing 10 includes an engine compartment 11 and an air intake chamber 12, which is located at the front of the engine compartment 11. The engine compartment 11 is provided with an air outlet, and the air intake chamber 12 is provided with an air inlet 13. The engine 20 is housed in the engine compartment 11. The hydraulic pump 30 is connected to the engine power and driven by the engine. The radiator 40 is installed in the hydraulic pipeline to dissipate heat from the hydraulic oil. The radiator 40 is located between the engine compartment 11 and the air intake chamber 12. The cooling fan 50 is located on one side of the engine compartment 11 near the air intake chamber 12 and is aligned with the radiator 40. When the cooling fan 50 is in operation, it drives the airflow in the air intake chamber 12 through the radiator 40 and into the engine compartment 11. When the engine 20 is running, its drive shaft drives the hydraulic pump 30 to operate. When the hydraulic pump 30 is in operation, it draws oil from the hydraulic oil tank and pressurizes and outputs the pressurized oil to the oil supply pipeline.

[0034] The cooling fan 50 of the engine 20 is one of the core components of the vehicle cooling system. Its main function is to assist the radiator in cooling down and ensure that the engine operates within an appropriate temperature range. When the cooling fan 50 is running, the external air flows into the air intake cavity 12 from the air inlet 13, and the air flow in the air intake cavity 12 passes through the radiator 40 and enters the engine compartment 11. Finally, the air flow in the engine compartment 11 is discharged from the air outlet. In this way, the external air passes through the air inlet 13, the air intake cavity 12, the radiator 40, the engine compartment 11, and the air outlet in sequence, thereby taking away the heat from the radiator 40 and the engine 20 and discharging it. The radiator 40 is installed in the hydraulic pipeline for heat dissipation of hydraulic oil. Therefore, the cooling fan 50 can dissipate heat for the engine 20 and the hydraulic system at the same time. In addition, the housing can protect the engine and other components, and the above heat dissipation channels are set based on the housing 10.

[0035] Because the radiator 40 is positioned between the engine compartment 11 and the intake chamber 12, air from the intake chamber 12 must pass through the radiator 40 when entering the engine compartment 11, dissipating heat from the radiator 40. It should be noted that the radiator 40 is installed in the hydraulic line to dissipate heat from the hydraulic oil, and its temperature is significantly lower than that of the engine. Therefore, placing the radiator 40 between the engine compartment 11 and the intake chamber 12 does not significantly affect engine heat dissipation. In this structural design, the engine's cooling fan 50 is utilized to dissipate heat for both the engine and the hydraulic system, reducing the need for hydraulic system heat dissipation, resulting in lower costs and a more compact structure.

[0036] In one embodiment of the present application, the cooling fan 50 is mounted on the engine and driven by the engine. Specifically, the cooling fan is directly connected to the engine crankshaft via a belt, operating synchronously with the engine, and its speed varies with the engine speed. In one embodiment of the present application, the cooling fan 50 is driven by an electric motor, operating independently of the engine and controlled by a controller, resulting in higher efficiency.

[0037] The engine compartment 11 is provided with an air outlet. In one embodiment of the present application, the air outlet includes a first air outlet 14, which is arranged at the top of the casing of the engine compartment 11. A first rain shielding structure 16 is provided on the first air outlet 14; the first rain shielding structure 16 includes a plurality of first strip-shaped baffles 161; from the highest first strip-shaped baffle 161 downward, the height of the first strip-shaped baffles 161 decreases successively and gradually covers the first air outlet 14 in the horizontal direction. There is a height difference between adjacent first strip-shaped baffles 161 and they partially overlap in the horizontal direction, and water can flow from high to low between the first strip-shaped baffles 161 until it flows to an area outside the first air outlet 14.

[0038] When the cooling fan 50 is running, airflow from the engine compartment 11 is discharged through the first rain shield structure 16, preventing rainwater from entering the engine compartment 11 and protecting the engine and other components. On the one hand, the height difference between adjacent first strip baffles 161 allows airflow to pass through the gaps between adjacent first strip baffles 161 and be discharged outside the engine compartment 11, without affecting engine heat dissipation. On the other hand, adjacent first strip baffles 161 partially overlap horizontally, guiding water flow from high to low between each first strip baffle 161, directing water flow to an area outside the first air outlet 14.

[0039] refer to Figure 4 and Figure 5 In one embodiment of the present application, the height of the first strip baffles 161 decreases from the highest position toward the sides, gradually covering the first air outlet 14 area on both sides in the horizontal direction. Furthermore, the first strip baffles 161 on both sides of the highest first strip baffle 161 are arranged symmetrically. With this structure, rainwater can flow along the first strip baffle 161 at the highest position in the middle to the sides, toward the edges of the first air outlet 14, and then be discharged outside the first air outlet 14.

[0040] In one embodiment of the present application, the first strip-shaped baffles are arranged in a descending order from one edge of the first air outlet to the other edge thereof, gradually covering the first air outlet in a horizontal direction. This structure is not shown in the accompanying drawings. With this structure, rainwater can flow from one edge of the first air outlet to the other side, thereby being discharged outside the first air outlet.

[0041] An exhaust duct is arranged on at least one side of the engine compartment 11; the exhaust duct is formed with a second air outlet 15 on the top of the casing on the side of the engine compartment, and the second air outlet 15 is provided with a second rain shield structure 17; the second rain shield structure 17 includes a plurality of second strip baffles; from the second strip baffle at the highest position downward, the height of the second strip baffles decreases successively and gradually covers the second air outlet 15 in the horizontal direction, and there is a height difference between adjacent second strip baffles and partially overlaps in the horizontal direction, and the water flow can flow from high to low between each second strip baffle until it flows to the area outside the second air outlet 15.

[0042] When the cooling fan 50 is running, airflow within the engine compartment 11 is discharged through the second rain shield structure 17, preventing rainwater from entering the engine compartment 11 and protecting the engine and other components. On the one hand, the height difference between adjacent second strip baffles allows airflow to pass through the gaps between them and be discharged outside the engine compartment 11, without affecting engine heat dissipation. On the other hand, adjacent second strip baffles partially overlap horizontally, guiding water flow from high to low between them, directing water flow to an area outside the first air outlet 14.

[0043] In one embodiment of the present application, the height of the second strip baffles decreases from the highest position toward the sides, gradually covering the second air outlet area on both sides in the horizontal direction. In this structural form, rainwater can flow along the second strip baffle at the highest position in the middle to the sides to the edges of the second air outlet, and then be discharged outside the second air outlet.

[0044] In one embodiment of the present application, the second strip-shaped baffles are arranged in a descending order from one edge of the second air outlet to the other edge thereof, gradually covering the second air outlet 15 in the horizontal direction. In this structural form, rainwater can flow from one edge of the second air outlet to the other side, thereby being discharged outside the second air outlet.

[0045] An embodiment of the present application also provides a mobile drainage device, including the power system provided in the above part.

[0046] The powertrain system includes a housing, an engine, a hydraulic pump, a radiator, and a cooling fan. The housing houses an engine compartment and an air intake chamber, located at the front of the engine compartment. The engine compartment has an air outlet, and the air intake chamber has an air inlet. The engine is housed within the engine compartment. The hydraulic pump is connected to the engine power source and driven by the engine. A radiator is installed in the hydraulic pipeline to dissipate heat from the hydraulic oil. The radiator is located between the engine compartment and the air intake chamber. The cooling fan is located within the engine compartment, near the air intake chamber, and aligned with the radiator. When the cooling fan is in operation, it drives air from the air intake chamber through the radiator and into the engine compartment. When the engine is running, its drive shaft drives the hydraulic pump, which draws oil from the hydraulic oil tank and pressurizes it to the oil supply pipeline. The radiator is installed in the hydraulic pipeline to dissipate heat from the hydraulic oil. Its temperature is significantly lower than that of the engine. Therefore, placing the radiator between the engine compartment and the air intake chamber does not significantly affect engine heat dissipation. This structural design utilizes the engine's cooling fan to dissipate heat for both the engine and the hydraulic system, reducing the need for hydraulic system cooling, resulting in lower costs and a more compact structure.
