Description

Technical Field

[0001] This utility model relates to the field of excavator technology, and in particular to a detachable fuel tank insulation sleeve, fuel tank, and excavator. Background Technology

[0002] For mining excavators operating in extremely cold regions, the diesel fuel tanks, being almost entirely made of metal, exhibit excellent thermal conductivity and convection, leading to significant heat loss. Diesel fuel at low temperatures is prone to waxing, resulting in poor flowability and increased fuel inlet resistance, affecting normal engine fuel supply and smooth power output. During operation, not all diesel fuel enters the engine and is burned; a considerable portion returns to the fuel tank after being heated. For example, a certain type of V12 engine has a maximum inlet flow rate of 510 L / h and a maximum return flow rate of 304 L / h. Therefore, in addition to using low-temperature diesel fuel that matches the ambient temperature, minimizing heat loss from the fuel tank during operation is crucial for protecting the engine's fuel supply. In hot summer months, excessively high fuel inlet temperatures can also affect engine operation. Besides using an independent fuel radiator, auxiliary heating devices for the diesel fuel tank should be shut down, and the fuel tank insulation sleeve should be removed promptly.

[0003] To overcome this problem, existing technologies have proposed methods to increase diesel fuel temperature by connecting various external auxiliary heating devices. These heating devices can effectively reduce the viscosity of diesel fuel, ensuring normal engine operation in low-temperature environments.

[0004] However, most auxiliary heating devices currently on the market are designed primarily to directly heat diesel fuel to maintain its temperature, with less attention paid to heat loss due to conduction and convection between the fuel tank and the outside air. This design strategy not only increases the cost of the equipment but also hinders energy conservation because it requires a continuous supply of additional energy for heating. Furthermore, auxiliary heating systems typically consist of multiple parts and complex piping, making installation complicated and requiring the removal of numerous excavator attachments and connecting pipes for maintenance, significantly increasing maintenance costs and time. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a detachable fuel tank insulation sleeve, fuel tank and excavator, which can solve the problems of low energy utilization and high installation and maintenance costs caused by setting auxiliary heating devices.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A detachable fuel tank insulation sleeve, comprising:

[0008] The first plate component includes a first plate body and a second plate body, the first plate body and the second plate body are connected in an L-shape, and the first plate body and the second plate body are integrally formed.

[0009] The second plate includes a third plate, a fourth plate, and a fifth plate, wherein the third plate, the fourth plate, and the fifth plate are sequentially connected in a U-shape, and the third plate, the fourth plate, and the fifth plate are integrally formed.

[0010] Third plate component;

[0011] The second plate has its two ends respectively attached to the end faces of the third plate and the fifth plate, and the second plate, the third plate, the fourth plate and the fifth plate form a rectangular enclosure with openings at both ends. The first plate covers one end of the rectangular enclosure, and the third plate covers the other end of the rectangular enclosure to form a cavity for accommodating the fuel tank. The first plate, the second plate, the third plate, the fourth plate, the fifth plate or the third plate are provided with clearance holes for the fuel tank's filler neck to communicate with the outside.

[0012] Furthermore, one or all of the first plate, the second plate, the third plate, the fourth plate, the fifth plate, and the third plate are composed of a flame-retardant coated cloth layer, an aluminum silicate fiber layer, and a carbon fiber cloth layer, wherein the aluminum silicate fiber layer is located between the flame-retardant coated cloth layer and the carbon fiber cloth layer, and the carbon fiber cloth layer is located on the side closer to the fuel tank.

[0013] Furthermore, the clearance hole is provided on the first plate, and the first plate has a first reserved opening.

[0014] Furthermore, the third plate is provided with a second reserved opening for the oil tank outlet to communicate with the outside.

[0015] Furthermore, the first plate, the second plate, the third plate, the fourth plate, the fifth plate, and the third plate are all provided with connecting holes for screws to pass through the connecting holes and connect to the oil tank.

[0016] Furthermore, the first plate is provided with a flange.

[0017] This utility model also provides an oil tank, including the above-mentioned detachable oil tank insulation sleeve and oil tank body;

[0018] The first plate, the second plate, the third plate, the fourth plate, the fifth plate, and the third plate respectively wrap around the six sides of the fuel tank body, and the first plate, the second plate, the third plate, the fourth plate, the fifth plate, and the third plate are fitted to the outer surface of the fuel tank body, and the first plate, the second plate, the third plate, the fourth plate, the fifth plate, and the third plate are provided with protrusions or depressions that conform to the outer surface of the fuel tank body.

[0019] Furthermore, the top surface of the fuel tank body is provided with a plurality of connecting lugs, and the first plate body is provided with a first reserved opening in both number and position corresponding to the connecting lugs, so that all the connecting lugs can pass through the first reserved opening.

[0020] This utility model also provides an excavator, including the above-mentioned detachable fuel tank insulation sleeve.

[0021] In summary, the detachable fuel tank insulation sleeve, fuel tank, and excavator provided by this utility model have the following technical effects:

[0022] 1. By completely enclosing the fuel tank within a cavity consisting of a first plate, a second plate, and a third plate, the direct contact between the fuel tank and the outside cold air is effectively reduced, thereby reducing heat loss caused by heat conduction and convection. This helps to better maintain the diesel temperature inside the fuel tank, prevents the diesel viscosity from increasing due to low temperatures, ensures normal fuel supply to the engine under cold conditions, and allows the first, second, and third plates to be easily removed when the temperature is high to ensure heat dissipation of the fuel tank.

[0023] 2. By disassembling the insulation jacket into a first panel (L-shaped), a second panel (U-shaped), and a third panel (flat panel), these components can be manufactured independently and then quickly assembled into a complete insulation jacket on-site or in the factory. This modular design simplifies the production and assembly process, reduces installation time and complexity, and improves work efficiency.

[0024] 3. Since the insulation jacket is made up of multiple panels rather than a single structure, it can be easily processed by bending a single panel.

[0025] 4. If a problem occurs in a certain part or adjustments are needed according to specific requirements, only the corresponding panel needs to be addressed, without disassembling the entire insulation sleeve. Attached Figure Description

[0035] See Figures 1-4This utility model discloses a detachable fuel tank insulation sleeve, comprising a first plate, a second plate, and a third plate 6. The first plate includes a first plate body 1 and a second plate body 2, which are connected in an L-shape and are integrally formed. The second plate includes a third plate body 3, a fourth plate body 4, and a fifth plate body 5, which are sequentially connected in a U-shape and are integrally formed. The second plate body 2... The two ends are respectively attached to the end face of the third plate 3 and the end face of the fifth plate 5, and the second plate 2, the third plate 3, the fourth plate 4 and the fifth plate 5 form a rectangular enclosure with openings at both ends. The first plate 1 covers the opening at one end of the rectangular enclosure, and the third plate 6 covers the opening at the other end of the rectangular enclosure to form a cavity for accommodating the oil tank. The first plate 1, the second plate 2, the third plate 3, the fourth plate 4, the fifth plate 5 or the third plate 6 are provided with clearance holes 11 for the oil tank's filling port to communicate with the outside.

[0036] Specifically, the first plate component includes a first plate 1 and a second plate 2. The first plate 1 and the second plate 2 are connected in an L-shape and are integrally formed. The first plate 1 has a clearance hole 11 for the fuel tank's filler neck to communicate with the outside. The second plate component includes a third plate 3, a fourth plate 4, and a fifth plate 5. The third plate 3, the fourth plate 4, and the fifth plate 5 are sequentially connected in a U-shape and are also integrally formed. The two ends of the second plate 2 are respectively attached to the end faces of the third plate 3 and the fifth plate 5, forming a rectangular enclosure with openings at both ends. The first plate 1 covers one end of the rectangular enclosure, and the third plate 6 covers the other end of the rectangular enclosure, thus forming a complete cavity together with the first plate 1 to accommodate the fuel tank. The cavity formed by the first, second, and third plates 6 effectively reduces direct contact between the fuel tank and the outside cold air, minimizing heat loss, maintaining diesel fuel temperature, preventing increased diesel viscosity due to low temperatures, and ensuring normal fuel supply to the engine. Generally, the third plate 6 is a flat plate, while the corresponding first plate is L-shaped and the second plate is U-shaped. Both can be manufactured using conventional plate bending techniques, making this protective sleeve easier to produce and transport compared to a one-piece molded sleeve. Furthermore, the insulation sleeve is not a single piece fitted over the fuel tank, but rather assembled from three U-shaped, L-shaped, and flat plates, greatly simplifying the assembly process and allowing for better adaptation to existing fuel tanks of different shapes and sizes.

[0037] In some embodiments, one or all of the first plate 1, the second plate 2, the third plate 3, the fourth plate 4, the fifth plate 5, and the third plate 6 are composed of a flame-retardant coated cloth layer, an aluminum silicate fiber layer, and a carbon fiber cloth layer, wherein the aluminum silicate fiber layer is located between the flame-retardant coated cloth layer and the carbon fiber cloth layer, and the carbon fiber cloth layer is located on the side closer to the fuel tank.

[0038] Specifically, the first plate 1, second plate 2, third plate 3, fourth plate 4, fifth plate 5, and third plate 6 can be composed of one or all of the following layers: a flame-retardant coated cloth layer, an aluminum silicate fiber layer, and a carbon fiber cloth layer, as needed. The flame-retardant coated cloth layer, located on the outermost layer, possesses flame-retardant properties, effectively preventing fire risks. It also provides additional wear resistance and waterproofing, protecting the internal materials from external environmental influences. The aluminum silicate fiber layer, located in the middle layer between the flame-retardant coated cloth layer and the carbon fiber cloth layer, is a highly efficient thermal insulation material with a low thermal conductivity, significantly reducing heat transfer and maintaining a stable temperature inside the tank. The carbon fiber cloth layer also maintains its physical properties over a wide temperature range. The carbon fiber cloth layer, located on the innermost layer, is in direct contact with the tank surface. It is not only high-strength and lightweight but also has excellent thermal conductivity, helping to quickly conduct heat from the tank surface to the aluminum silicate fiber layer, further improving the insulation effect. In addition, carbon fiber cloth is corrosion-resistant and can be used for a long time in harsh environments without easily being damaged. Placing the carbon fiber cloth layer on the innermost side closest to the fuel tank allows heat to be captured more effectively by the aluminosilicate fiber layer, while the high strength of the carbon fiber resists physical impacts or abrasion that may come from outside the fuel tank.

[0039] In some embodiments, the clearance hole 11 is provided on the first plate 1, and the first plate 1 is provided with a first reserved opening 12.

[0040] Specifically, the clearance hole 11 is provided on the first plate 1 to ensure that the user can easily access the fuel tank filler neck. This allows the operator to easily perform refueling operations without obstruction even when the first plate is assembled. The first reserved opening 12 is designed to accommodate the connecting lug 82 on the fuel tank, especially the diesel tank of an excavator, which usually has a connecting lug 82 on the top. The first reserved opening 12 facilitates the installation of the first plate without being affected by the protruding connecting lug 82, and it does not affect the connection between the connecting lug 82 and other components. Furthermore, the first reserved opening 12 is designed to fit the size of the connecting lug 82. After the connecting lug 82 is inserted into the first reserved opening 12, it will also engage with the first reserved opening 12, thus also playing a certain positioning role.

[0041] In some embodiments, the third plate 6 is provided with a second reserved opening 61 for communicating the oil outlet of the oil tank with the outside.

[0042] Specifically, the main function of the second reserved port 61 is to ensure that the fuel tank outlet can be smoothly connected to an external fuel supply system (such as an engine or other fuel-using equipment). This ensures that diesel fuel can flow from the fuel tank into components such as the engine, supporting the normal operation of the machinery. Even without the second reserved port 61, communication with the outside during fuel use can still be achieved through the clearance hole 11.

[0043] In some embodiments, the first plate 1, the second plate 2, the third plate 3, the fourth plate 4, the fifth plate 5 and the third plate 6 are all provided with connecting holes 7 for screws to pass through the connecting holes 7 and connect to the oil tank.

[0044] Specifically, the main function of the connecting hole 7 is to securely fix the various plates of the insulation sleeve to the surface of the oil tank with screws, ensuring that the insulation sleeve will not loosen or fall off due to mechanical vibration or external impact. Through multiple connection points, the insulation sleeve can fit tightly against the oil tank, improving the stability and reliability of the overall structure and preventing displacement or deformation caused by external factors.

[0045] Alternatively, when the screw passes through the connecting hole 7 to connect with the oil tank, a pressure plate and a washer can be installed on the screw to enhance the stability of the connection and prevent the screw from retracting during the vibration of the excavator.

[0046] In some embodiments, the first plate 1 is provided with a flange 13, and a flange plate is detachably provided on the flange 13, thereby facilitating manual cleaning and inspection of whether the internal oil tank is normal.

[0047] This utility model also provides an oil tank, including the above-mentioned detachable oil tank insulation sleeve and oil tank body; the first plate 1, the second plate 2, the third plate 3, the fourth plate 4, the fifth plate 5 and the third plate 6 respectively wrap the six sides of the oil tank body, and the first plate 1, the second plate 2, the third plate 3, the fourth plate 4, the fifth plate 5 and the third plate 6 are set to fit the outer surface of the oil tank body, and the first plate 1, the second plate 2, the third plate 3, the fourth plate 4, the fifth plate 5 and the third plate 6 are provided with protrusions or depressions that conform to the outer surface of the oil tank body.

[0048] Specifically, the first plate 1, second plate 2, third plate 3, fourth plate 4, fifth plate 5, and third plate 6 completely wrap around all six sides of the fuel tank body, ensuring complete coverage for optimal insulation. These plates fit snugly against the outer surface of the fuel tank body, eliminating any noticeable gaps or voids and minimizing heat loss. Furthermore, to better conform to the shape of the fuel tank body, the first plate 1, second plate 2, third plate 3, fourth plate 4, fifth plate 5, and third plate 6 feature protrusions or recesses that mimic the shape of the outer surface of the fuel tank body. This design not only improves the fit between the insulation sleeve and the fuel tank but also effectively disperses external impact forces, protecting the fuel tank from damage.

[0049] In some embodiments, the top surface of the fuel tank body is provided with a plurality of connecting ears 82, and the first plate 1 is provided with a first reserved opening 12 in number and position corresponding to the connecting ears 82, so that all the connecting ears 82 pass through the first reserved opening 12.

[0050] Specifically, the connecting lugs 82 are located on the top surface of the fuel tank body, mainly for facilitating the hoisting or fixing of the fuel tank body. The number and position of the connecting lugs 82 are adjusted according to the specific structure and usage requirements of the fuel tank body. The number of first reserved openings 12 on the first plate 1 is exactly the same as the number of connecting lugs 82 on the top surface of the fuel tank body, ensuring that each connecting lug 82 has a corresponding first reserved opening 12, and ensuring that there will be no deviation during installation.

[0051] This utility model also provides an excavator, including the above-mentioned detachable fuel tank insulation sleeve.

[0052] Specifically, the excavator is equipped with the aforementioned detachable fuel tank insulation sleeve. This sleeve consists of multiple plates (first plate 1, second plate 2, third plate 3, fourth plate 4, fifth plate 5, and third plate 6), which completely enclose the fuel tank body, ensuring that the fuel tank can maintain a stable diesel temperature even in cold conditions. Each plate of the insulation sleeve fits tightly against the outer surface of the fuel tank body and features contoured protrusions or recesses to adapt to the irregular shape of the fuel tank body, ensuring optimal insulation performance and mechanical strength.

[0053] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
