Description

Technical Field

[0001] This utility model belongs to the field of fuel tank technology, and specifically relates to a fuel tank. Background Technology

[0002] Existing fuel tanks have numerous shortcomings in terms of structural design and ease of maintenance. Traditional fuel tanks typically have core components such as pumps, valves, and pipelines installed separately inside or outside the tank, resulting in a dispersed layout and low integration. For example, the oil pump is often directly mounted on the bottom or side wall of the tank, while pressure valves, outlet pipes, interface modules, and other components are connected to the tank interior through complex piping. This design necessitates the disassembly of numerous components or deep penetration into the tank's reservoir to access critical parts during maintenance, making the process cumbersome and time-consuming, increasing labor costs and downtime. Furthermore, repairing the pressure regulation system or pipeline connections may require complete disassembly of the tank or frequent disassembly of multiple components, which can easily lead to seal failure or component damage due to repeated disassembly and reassembly, thus increasing the risk of secondary malfunctions.

[0003] In summary, existing fuel tanks have significant shortcomings in terms of ease of maintenance, efficiency in troubleshooting, and structural integration. There is an urgent need for a technical solution that can simplify the maintenance process and reduce operational complexity through modular integrated design.

[0004] Therefore, based on some of the situations in the prior art described above, this application has made further designs and improvements. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0006] An oil tank includes a tank body, a cover plate mounted on the top of the tank body, a bracket mounted on the bottom of the cover plate, an oil storage chamber provided inside the tank body, the bracket located inside the oil storage chamber, an oil pump mounted on the bracket, an oil suction port and an oil pumping port provided on the pump body, an oil outlet pipe connected to the oil pumping port, and the oil outlet pipe mounted on the cover plate.

[0007] Furthermore, a pressure valve is installed on the housing, and a return oil pipe is connected to the oil outlet pipe. The oil inlet of the pressure valve is connected to the return oil pipe, and the oil outlet of the pressure valve leads to the oil storage chamber.

[0008] Furthermore, the pressure valve is mounted on the cover plate.

[0009] Furthermore, the pump body is connected to an interface module, which is fixed to the cover plate.

[0010] Furthermore, a handle is provided on the top of the box, which is manufactured as a single piece with the box, and the handle is hollow inside.

[0011] Furthermore, a filter is connected to the oil inlet of the pump body.

[0012] Furthermore, a heat dissipation module is installed on the side of the enclosure.

[0013] Furthermore, a refueling cap is fitted on the top of the container.

[0014] Furthermore, the enclosure is made of plastic or corrosion-resistant metal.

[0015] The fuel tank of this application has the following beneficial technical effects:

[0016] 1. The core components, including the pump body, interface module, oil outlet pipe, and pressure valve, are centrally assembled on the top cover of the tank, forming a quickly detachable integrated module. During maintenance, only the cover needs to be removed to directly access all critical components, eliminating the cumbersome process of traditional tanks requiring complete disassembly or deep internal repairs. This design significantly shortens maintenance time, reduces labor costs, and minimizes the risk of secondary failures due to complex disassembly and assembly, making it particularly suitable for industrial scenarios requiring frequent maintenance or rapid on-site repairs.

[0017] 2. By connecting a return oil pipe to the outlet pipe and installing a pressure valve connected to the oil storage chamber, a closed-loop pressure regulation system is formed. When the pump output oil pressure exceeds the set threshold, the pressure valve automatically opens, allowing the high-pressure oil to flow back to the oil storage chamber through the return oil pipe. This effectively prevents safety hazards such as pipeline leakage, pump damage, or fuel splashing caused by excessive pressure. This design not only ensures the stable operation of the oil circuit system but also avoids energy waste, achieving the dual goals of dynamic pressure balance and safety protection.

[0028] Reference Figures 1 to 4 An oil tank includes a tank body 100, a cover plate 200 mounted on the top of the tank body 100, a bracket 210 mounted on the bottom of the cover plate 200, an oil storage chamber 101 disposed inside the tank body 100, the bracket 210 located inside the oil storage chamber 101, an oil pump 220 mounted on the bracket 210, the pump body having an oil suction port and a pumping port, the pumping port being connected to an oil outlet pipe 221, the oil outlet pipe 221 being mounted on the cover plate 200. The tank body 100 is made of plastic or corrosion-resistant metal. A handle 102 and an oil filler cap 110 are disposed on the top of the tank body 100, the handle 102 being integrally manufactured with the tank body 100, and the handle 102 being hollow inside. This design integrates key components such as the pump body onto the cover plate 200, forming a fully detachable integrated module. During maintenance, only the cover plate 200 needs to be removed to directly inspect all core components, significantly reducing the complex process of disassembling the tank body 100 or going deep into the cavity required by traditional oil tanks, thus reducing labor costs and improving maintenance efficiency.

[0029] To achieve pressure safety control, a pressure valve 230 is installed on the housing 100. A return oil pipe 222 is connected to the outlet pipe 221. The inlet of the pressure valve 230 is connected to the return oil pipe 222, and the outlet of the pressure valve 230 leads to the oil storage chamber 101. The pressure valve 230 is mounted on the cover plate 200. An interface module 223 is connected to the pump body and fixed to the cover plate 200. When the output pressure of the oil pump 220 exceeds a preset threshold, the pressure valve 230 automatically opens, allowing high-pressure fuel to flow back to the oil storage chamber 101 through the return oil pipe 222, forming a closed-loop pressure regulation system. This structure effectively prevents pipeline leakage, pump overload, or accidental fuel splashing, while avoiding energy waste and ensuring the system maintains stable pressure under dynamic operating conditions. Furthermore, a filter 224 is connected to the pump body's inlet to intercept impurities in the oil storage chamber 101, extending the service life of the pump body and pipelines.

[0030] Furthermore, a heat dissipation module 120 is installed on the side of the tank 100 to reduce fuel temperature by enhancing air convection or heat conduction structures, ensuring the reliability of the fuel tank in high-temperature environments. The bottom of the bracket 210 rests against the bottom wall of the fuel storage chamber 101. Reinforcing ribs 103 are provided on the side of the tank 100. The reinforcing ribs 103 and the bracket 210 work together to improve the overall structural strength and impact resistance.

[0031] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
