It features high portability, mobility, and adaptability to complex environments, allowing for rapid deployment to various work sites. It has been widely used in firefighting and emergency rescue, engineering and field operations, municipal and urban maintenance, agricultural and forestry machinery, and industrial equipment repair.

[0003] Current hydraulic power units suffer from unreasonable spatial structure design, which is not conducive to improving space utilization. As a result, the overall structure is too large, which is not conducive to reducing the space occupied, thus affecting the placement and movement during use. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a hydraulic power station that can improve space utilization, reduce the space occupied by the hydraulic power station, and facilitate placement and movement during use.

[0005] This utility model discloses a hydraulic power station, including: a chassis, a power output component and a fuel tank disposed on the chassis, wherein the fuel tanks are disposed on both sides in the width direction of the chassis so that the power output component is located between the two fuel tanks, the width of the fuel tank is less than 1 / 6 of the width of the chassis, and the fuel tank extends in a direction perpendicular to the plane of the chassis; wherein the fuel tank is connected to the engine of the power output component.

[0006] Optionally, the chassis is further provided with a hydraulic oil tank, which extends along the plane of the chassis; the power output assembly also includes a hydraulic pump connected to the engine, which is connected to the hydraulic oil tank.

[0007] Optionally, the front end of the chassis is connected to a caster wheel, and the rear end of the chassis is connected to a track wheel, wherein the diameter of the track wheel is larger than the diameter of the caster wheel.

[0008] Optionally, the fuel tank includes a first cavity and a second cavity that are interconnected. The first cavity and the second cavity are arranged in an L-shape. The first cavity extends along the length direction of the chassis, and the second cavity extends along the height direction of the chassis. The second cavity is fixedly connected to the chassis.

[0009] Optionally, a heat dissipation duct is provided at the connection between the first cavity and the second cavity. The bottom of the heat dissipation duct is detachably connected to the chassis. A latch is also provided on the heat dissipation duct, which can be engaged with the bottom of the first cavity.

[0010] Optionally, the bottom of each of the two second cavities is provided with a connection port, and the two connection ports are connected by a connecting pipe.

[0011] Optionally, the top of the first cavity is provided with an extension plate, which extends inward to facilitate connection with the vehicle body of the hydraulic power station. An oil filling port is provided on the extension plate of the first cavity, and the oil filling port communicates with the first cavity.

[0012] Optionally, a flow guide groove is also provided on the first cavity, the flow guide groove is located on one side of the first cavity, and the oil filling port is connected to the first cavity and the flow guide groove respectively.

[0013] Optionally, the top of the fuel tank is provided with a cover, and the two sides of the cover in the width direction respectively connect with the tops of the two fuel tanks.

[0014] Optionally, the cover includes a first cover and a second cover that are rotatably connected, and the first cover and the second cover are connected by a hinge.

[0015] Compared with the prior art, the beneficial effects of the hydraulic power station provided by this utility model embodiment are as follows: By placing the fuel tanks on both sides of the chassis width and centering the power output component, this symmetrical distribution rationally plans the space in the chassis width direction. This allows the core component, the power output component, to be properly surrounded by the fuel tanks on both sides, avoiding a cluttered distribution of components on the chassis and making the overall chassis layout more compact and orderly. The fuel tank width is less than 1 / 6 of the chassis width, meaning that a single fuel tank occupies less space in the chassis width direction, and the total width occupied by the two fuel tanks is also relatively narrow. This provides sufficient lateral space for the power output component in the middle, facilitating its installation and layout, while preventing the overall chassis width from becoming too large due to excessively wide fuel tanks. Furthermore, the fuel tanks extend vertically, expanding the space in the height direction. Without increasing the chassis footprint (i.e., the chassis's projected area on the horizontal plane), the volume of the fuel tanks is increased, making full use of the vertical space and improving space utilization. This layout allows for control over the overall lateral dimensions (chassis width) of the hydraulic power unit, improving space utilization. It avoids excessive width due to the arrangement of the fuel tank and power output components, thus reducing the space occupied by the hydraulic power unit. This makes the unit more flexible in movement, facilitating placement and relocation, especially in confined spaces. For example, in fire and emergency rescue scenarios, rapid deployment of equipment may be necessary in narrow corridors and alleys; the narrower chassis width and compact layout make it easier for the equipment to pass through and park.

Detailed Implementation

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a hydraulic power station 100, including: a chassis 110, a power output assembly 120 and a fuel tank 130 disposed on the chassis 110. The fuel tanks 130 are disposed on both sides of the chassis 110 in the width direction, so that the power output assembly 120 is located between the two fuel tanks 130. The width of the fuel tanks 130 is less than 1 / 6 of the width of the chassis 110, and the fuel tanks 130 extend in a direction perpendicular to the plane of the chassis 110. The fuel tanks 130 are connected to the engine of the power output assembly 120.

[0025] Specifically, the fuel tank 130 is connected to the engine of the power output assembly 120 to supply fuel to the engine. The width of the fuel tank 130 can be flexibly set according to the overall size of the hydraulic power unit 100; for example, it can be set to 1 / 6, 1 / 7, or 1 / 8 of the width of the chassis 110.

[0026] The hydraulic power unit 100 provided in this application embodiment, by placing the fuel tanks 130 on both sides of the width of the chassis 110 and centering the power output component 120, rationally plans the space in the width direction of the chassis 110. This allows the core component, the power output component 120, to be reasonably surrounded by the fuel tanks 130 on both sides, avoiding a cluttered distribution of components on the chassis 110 and making the overall layout of the chassis 110 more compact and orderly. The width of the fuel tanks 130 is less than 1 / 6 of the width of the chassis 110, meaning that the space occupied by a single fuel tank 130 in the width direction of the chassis 110 is small, and the total width occupied by the fuel tanks 130 on both sides is also relatively narrow. This leaves sufficient lateral space for the power output component 120 in the middle, facilitating the installation and layout of the power output component 120, while also preventing the overall width of the chassis 110 from becoming too large due to the fuel tanks 130 being too wide. The fuel tank 130 extends vertically, expanding space in the height direction. Without increasing the footprint of the chassis 110 (i.e., the projected area of ​​the chassis 110 on the horizontal plane), the volume of the fuel tank 130 is increased, making full use of vertical space and improving space utilization. This layout allows for control of the lateral dimensions of the entire hydraulic power station 100 (width of the chassis 110), improving space utilization. It prevents the fuel tank 130 and power output component 120 from becoming too wide, thus reducing the space occupied by the hydraulic power station 100. This makes the hydraulic power station 100 more flexible in movement, facilitating placement and relocation, especially in confined spaces. For example, in fire and emergency rescue scenarios, rapid deployment of equipment may be required in narrow corridors and alleys. The narrower chassis 110 width and compact layout make it easier for the equipment to pass through and park, and it also has wider applicability in other scenarios.

[0027] like Figure 2 As shown, a hydraulic oil tank 140 is also provided on the chassis 110, and the hydraulic oil tank 140 extends along the plane of the chassis 110; the power output assembly 120 also includes a hydraulic pump connected to the engine, and the hydraulic pump is connected to the hydraulic oil tank 140.

[0028] Specifically, the fuel tank 130 utilizes space vertically, while the hydraulic oil tank 140 extends horizontally. These two components expand space in different dimensions, further optimizing the spatial layout of the chassis 110. This allows for a more rational distribution of components on the chassis 110, fully utilizing both planar and vertical space and improving overall space utilization. The hydraulic pump is connected to the engine, which provides power. The hydraulic pump is then connected to the hydraulic oil tank 140, forming a complete hydraulic power transmission system. The hydraulic oil tank 140 supplies hydraulic oil to the hydraulic pump, which converts the engine's mechanical energy into hydraulic energy to power the various actuators of the hydraulic system. This arrangement makes the storage and transmission of hydraulic fluid smoother. The rational layout of the hydraulic oil tank 140 ensures sufficient hydraulic oil reserves, and its proximity to the hydraulic pump reduces the distance and resistance of oil transmission, improving the efficiency and stability of the hydraulic system. For example, in engineering and field operations, the hydraulic system needs to work continuously and stably. The proper setting of the hydraulic oil tank 140 and the effective connection between the hydraulic pump and the oil tank can ensure that the hydraulic system maintains good performance during long-term operation, reduce failures caused by oil supply problems, and improve the working reliability and efficiency of the hydraulic power station 100.

[0029] like Figure 1 and Figure 2 As shown, the front end of the chassis 110 is connected to a caster wheel 150, and the rear end of the chassis 110 is connected to a traveling wheel 160, and the diameter of the traveling wheel 160 is larger than the diameter of the caster wheel 150.

[0030] Specifically, the front swivel casters 150 make the equipment more flexible and convenient to turn, enabling it to turn on the spot or make small-radius turns in confined spaces, improving its maneuverability in complex environments. The rear travel wheels 160 have a larger diameter, providing better passability when traversing uneven, muddy, or obstacle-filled surfaces compared to smaller diameter wheels. The larger diameter reduces the likelihood of the wheels getting stuck in the ground and allows for better crossing of small obstacles during movement, reducing equipment vibration and ensuring stability during movement. For example, in agricultural and forestry machinery operations, the ground may contain potholes, grass, small stones, and other complex terrain. The larger diameter travel wheels 160 allow the equipment to pass through these areas more smoothly, reducing movement difficulties caused by wheel issues and improving the equipment's applicability and operational efficiency. Simultaneously, the different configurations of the front and rear wheels create a reasonable support and drive structure. The front swivel casters 150 are responsible for flexible steering, while the rear travel wheels 160 provide primary support and propulsion, making the equipment move more smoothly and efficiently, reducing the operator's workload and improving ease of use.

[0031] like Figure 2 and Figure 3As shown, the fuel tank 130 includes a first cavity 132 and a second cavity 134 that are interconnected. The first cavity 132 and the second cavity 134 are arranged in an L-shape. The first cavity 132 extends along the length direction of the chassis 110, and the second cavity 134 extends along the height direction of the chassis 110. The second cavity 134 is fixedly connected to the chassis 110.

[0032] Specifically, the first cavity 132 extends along the length of the chassis 110, making full use of the space in the longitudinal direction of the chassis 110, while the second cavity 134 extends along the vertical direction, utilizing the space in the vertical direction. This three-dimensional layout allows the fuel tank 130 to maximize its volume within the limited space of the chassis 110, without occupying too much of the chassis 110's planar area. The two interconnected second cavities 134 ensure the flow of fuel throughout the entire fuel tank 130, ensuring that the engine can stably obtain fuel. The second cavities 134 are fixedly connected to the chassis 110, improving the stability of the fuel tank 130's installation and preventing the fuel tank 130 from shaking or shifting due to bumps or other reasons during equipment movement, thus ensuring the reliability of fuel supply.

[0033] like Figure 2 As shown, a heat dissipation duct 170 is provided at the connection between the first cavity 132 and the second cavity 134. The bottom of the heat dissipation duct 170 is detachably connected to the chassis 110. A latch 172 is also provided on the heat dissipation duct 170, which can be engaged with the bottom of the first cavity 132.

[0034] Specifically, the cooling duct 170 is designed to help dissipate heat from the hydraulic oil in the hydraulic tank, as the hydraulic oil generates a large amount of heat during operation, and excessively high temperatures can affect the stability of the hydraulic drive. The cooling duct 170 is located at the connection between the first chamber 132 and the second chamber 134, utilizing the space around the fuel tank 130 to form a heat dissipation channel. This allows outside air to enter the internal space of the hydraulic power station through the cooling duct 170, carrying away a significant amount of heat and ensuring the hydraulic oil temperature remains stable within a suitable range. The bottom of the cooling duct 170 is detachably connected to the chassis 110, and combined with the engagement of the latch 172 with the first chamber 132, it facilitates the disassembly of the cooling duct 170 during maintenance of the hydraulic power station 100. This allows for inspection, cleaning, and repair of the engine or the cooling duct 170 itself, reducing maintenance costs and complexity.

[0035] like Figure 4 As shown, the bottom of each of the two second cavities 134 is provided with a pair of interfaces 1342, and the two pairs of interfaces 1342 are connected by a connecting pipe.

[0036] Specifically, the two fuel tanks 130 are connected via an interface 1342 and a connecting pipe, enabling free flow of fuel between them. This effectively combines the two fuel tanks 130 into a larger fuel storage system. The connecting pipe can be a flexible hose. This balances the fuel quantity in the two fuel tanks 130, preventing situations where one tank consumes fuel too quickly while the other still has a lot of fuel. This ensures the engine can obtain fuel evenly from both tanks, improving fuel efficiency and stability. Simultaneously, the interconnected structure allows for effective utilization of the total volume of the fuel tanks 130, preventing a reduction in usable volume due to uneven fuel distribution in any single tank.

[0037] like Figure 3 As shown, the top of the first cavity 132 is provided with an extension plate 1322, which extends inward to facilitate connection with the body of the hydraulic power station 100. An oil filling port 1324 is provided on the extension plate 1322 of the first cavity 132, and the oil filling port 1324 is connected to the first cavity 132.

[0038] Specifically, the extension plate 1322 provides a reliable structure for the connection between the fuel tank 130 and the vehicle body. The inward extension design makes the connection more compact, better matching the vehicle body structure, improving the stability of the fuel tank 130 installation, reducing relative shaking between the fuel tank 130 and the vehicle body during movement, and ensuring the stability of the fuel tank 130. The filler neck 1324 is located on the extension plate 1322 of one of the first chambers 132. Its relatively high position makes it easy for operators to locate the filler neck 1324 when refueling, improving refueling convenience. Simultaneously, the filler neck 1324 communicates with one of the first chambers 132, ensuring that fuel can smoothly enter the fuel tank 130, and the connecting pipe enables interconnection of fuel lines.

[0039] like Figure 3 As shown, a flow guide 1326 is also provided on the first cavity 132. The flow guide 1326 is located on one side of the first cavity 132, and the oil filling port 1324 is connected to the first cavity 132 and the flow guide 1326 respectively.

[0040] Specifically, the main function of the flow guide 1326 is to guide the flow of fuel during refueling, preventing fuel from overflowing outside the fuel tank 130. When refueling through the filler neck 1324, if the refueling speed is too fast or the operator is careless, fuel may splash out. The flow guide 1326 allows fuel to smoothly enter the fuel tank 130, reducing the possibility of overflow due to excessively fast refueling. In addition, since the width of the fuel tank 130 is relatively small, it is not convenient to directly set the filler neck 1324 on the top. By setting the flow guide 1326 to cooperate with the filler neck 1324, the orthographic projection of the filler neck 1324 can correspond to the first cavity 132 and the flow guide 1326 respectively, which facilitates the setting of the filler neck 1324 and improves the smoothness of refueling.

[0041] like Figure 1 and Figure 2 As shown, a cover 180 is provided on the top of the fuel tank 130, and the two sides of the cover 180 in the width direction respectively connect with the top of the two fuel tanks 130.

[0042] Specifically, the cover 180 and the fuel tank 130 are connected and combined to form the outer shell protection system of the hydraulic power unit 100, providing all-round physical protection for the hydraulic power unit 100, reducing the intrusion of external dust, debris, and rainwater, and thus protecting the hydraulic power unit 100. At the same time, the cover 180 and the fuel tank 130 work together to have sound insulation and noise reduction functions, which can significantly reduce the noise generated during engine operation, reduce the propagation of noise, and thus reduce the overall noise of the hydraulic power unit 100.

[0043] like Figure 2 As shown, the cover 180 includes a first cover 182 and a second cover 184 that are rotatably connected, and the first cover 182 and the second cover 184 are connected by a hinge 186.

[0044] Specifically, the first cover 182 and the second cover 184 are connected by a hinge 186, making the opening and closing of the cover 180 more convenient and flexible. When it is necessary to inspect, maintain, or refuel the fuel tank 130, the corresponding first cover 182 or second cover 184 can be opened as needed without removing the entire cover 180, thus improving operational convenience. When it is necessary to repair the power output assembly 120, only the corresponding first cover 182 or second cover 184 needs to be opened.

[0045] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
