Description
Technical Field
[0001] This utility model relates to the field of fuel supply equipment technology, and more specifically, to a yacht fuel tank structure. Background Technology
[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.
[0003] As a high-end water recreation and sports tool, the yacht's endurance and operational reliability are key indicators for measuring its quality. As the energy heart of the yacht, the performance of the fuel tank directly determines the yacht's range and the stability of its power output. When sailing in water, yachts need to cope with complex conditions such as long-distance and high-speed cruising, which requires the fuel tank to have large capacity and reliable characteristics. Therefore, the scientific design of the fuel tank structure is not only related to the yacht's economy and efficiency, but also a core link in ensuring the safety of passengers and protecting the water environment, and is of extremely high importance.
[0004] Currently, the mainstream yacht fuel tanks on the market are usually sealed containers made of corrosion-resistant, high-strength materials, such as polyethylene plastic or aluminum alloy. Their shape is designed according to the space of the hull, such as cube, cylinder or other irregular shape. They mainly consist of the tank body, which is used to store fuel. A refueling port is opened on the top or side wall of the tank body. The tank body is equipped with a fuel system, mainly including fuel outlet pipe and fuel return pipe, so as to replenish the fuel inside the tank.
[0005] However, the aforementioned technologies have the following drawbacks: during refueling, the filler neck serves the dual function of filling the tank with fuel and facilitating the exchange of gases between the inside and outside of the tank. When a large amount of fuel is rapidly injected, the air inside the tank needs to be quickly expelled to balance the pressure inside and outside the tank. However, when the air is expelled, the gasoline inside the tank will evaporate into the air, causing environmental pollution. At the same time, the evaporated gasoline also poses certain safety hazards, thus affecting the user experience. Utility Model Content

The elastic modulus of the second elastic element is greater than that of the first elastic element.
[0011] In some possible embodiments, the bottom of the cover plate is provided with a sliding groove, and a slider is slidably disposed in the sliding groove.

[0016] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:
[0017] 1. By opening a vent hole on the side wall of the fuel filler pipe and connecting it to the vent pipe, efficient exchange of gases inside and outside the fuel tank is achieved during refueling. When fuel is injected quickly, the air inside the fuel tank is smoothly discharged through the vent pipe, effectively balancing the internal and external pressures. This avoids rapid gasoline evaporation to a certain extent, reduces gasoline evaporation in a short period of time, and thus improves environmental benefits. At the same time, it avoids the problem of reduced refueling speed caused by air resistance in traditional designs, ensuring continuous and rapid fuel filling, significantly shortening refueling time, and further shortening the time window for gasoline evaporation. This not only improves environmental benefits but also enhances the yacht's endurance preparation efficiency to a certain extent. It is especially suitable for long-distance sailing or frequent refueling scenarios, thereby optimizing the overall energy replenishment process.
[0018] 2. The sealing assembly, through the synergistic action of the vent hole and vent pipe, prevents abnormal increases in internal air pressure during refueling, avoiding potential damage to the fuel system or fuel leakage due to pressure buildup. The limiting and positioning components of the cover plate ensure a tight seal at the fuel inlet, preventing accidental opening due to vibration or impact during navigation, further reducing safety hazards, ensuring the stable operation of the yacht, and reducing potential threats to the environment and occupants, in compliance with high safety standards.
[0019] 3. The rotating design of the cover plate, combined with a limit mechanism, makes opening and closing operations simpler. The cover plate can be fixed or released with a simple action. The coordinated work of the limit block and the positioning component ensures the stability of the cover plate in the closed state, avoiding loosening or repeated adjustments due to improper operation. It also reduces the cumbersome steps in the refueling process, improves the user's operating comfort and satisfaction, and is in line with the functional positioning of the yacht as a high-end leisure tool.
[0020] 4. The design employs a combination of T-grooves and T-slider, with embedded ball bearings to reduce friction, ensuring smooth movement of the limit block within the groove and reducing component wear. The rational configuration of the first and second elastic elements provides necessary buffering and reset functions, enhancing the reliability and adaptability of the overall structure. The abutment design between the limit strip and the fixed block further strengthens the connection stability, enabling the fuel tank structure to maintain stable performance even in harsh marine environments, reducing maintenance frequency and costs.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0030] The following is for reference Figures 1 to 7 The present invention will be described in further detail below.
[0031] Reference Figure 1 and Figure 2 A yacht fuel tank structure includes a tank body 1, with an oil inlet 11 on the top of the tank body 1, and the oil inlet 11 communicating with the interior of the tank body 1.
[0032] Reference Figure 1 and Figure 2 The housing 1 is provided with a sealing component 2, which is used to open or close the oil inlet 11. As one embodiment of this utility model, the sealing component 2 includes a mounting part 21, an oil injection pipe 22 and a cover plate 23.
[0033] Reference Figure 2 and Figure 3 The mounting part 21 is provided on the oil inlet 11, and the mounting part 21 is provided with a mounting plate. The oil injection pipe 22 is provided through the mounting plate and passes through the oil inlet 11. The side wall of the oil injection pipe 22 is provided with a vent hole 24, and a vent pipe 25 is connected to the vent hole 24. The cover plate 23 is rotatably mounted on the mounting part 21.
[0034] Reference Figure 4 and Figure 5 A limiting member 3 is provided on the mounting part 21, which is used to limit the position of the cover plate 23 on the mounting part 21.
[0035] As one embodiment of this utility model, refer to Figure 3 , Figure 4 and Figure 5 The limiting member 3 is set as a limiting strip. The bottom of the cover plate 23 is slidably provided with a limiting block 31 in the horizontal direction. The top of the mounting part 21 is provided with a limiting groove 32 for the limiting block 31 to be inserted. The limiting strip is fixedly set on the inner wall of the limiting groove 32 along the length direction of the limiting groove 32. A fixing block 33 is provided on the limiting block 31. The top of the fixing block 33 is used to abut against the bottom of the limiting strip. A first elastic member 34 is provided on the cover plate 23. The first elastic member 34 acts on the limiting block 31 to make the limiting block 31 move away from the limiting strip. A positioning member 4 is provided on the mounting part 21. The positioning member 4 is used to limit the position of the limiting block 31 in the limiting groove 32.
[0036] Reference Figure 5 and Figure 6 The positioning element 4 is configured as a positioning block. A through hole 41 is provided on the side wall of the mounting part 21. The through hole 41 communicates with the limiting groove 32. The positioning element 4 is slidably disposed in the through hole 41 in the vertical direction. A first inclined surface 42 is provided at one end of the positioning element 4 located in the limiting groove 32. The first inclined surface 42 is inclined towards the direction close to the limiting block 31. A second inclined surface 43 is provided at the bottom end of the side of the limiting block 31 close to the positioning element 4. The second inclined surface 43 abuts against the first inclined surface 42. The inclination angle of the second inclined surface 43 is adapted to the first inclined surface 42. A second elastic element 44 is provided on the mounting part 21. The second elastic element 44 acts on the positioning element 4 so that the positioning element 4 has an upward movement tendency. The elastic modulus of the second elastic element 44 is greater than the elastic modulus of the first elastic element 34.
[0037] Reference Figure 5 The bottom end of the limiting block 31 near the limiting strip is provided with a third inclined surface 45. The third inclined surface 45 is inclined towards the limiting strip and is used to slide and contact the limiting strip.
[0038] In actual use, after refueling the tank, flipping the cover plate 23 causes the limiting block 31 to insert into the limiting groove 32. At this time, the limiting block 31 is positioned under the action of the first elastic element 34. Figure 5 At the far right of the middle sliding groove 5, the projections of the fixing block 33 and the limiting strip in the vertical direction do not intersect. As the cover plate 23 is fastened, the limiting block 31 is inserted into the limiting groove 32. The second inclined surface 43 at the bottom of the limiting block 31 abuts against the first inclined surface 42. Since the elastic modulus of the second elastic element 44 is greater than that of the first elastic element 34, the elastic deformation generated by the second elastic element 44 is much smaller than that generated by the first elastic element 34. Therefore, under the action of the first inclined surface 42 on the positioning element 4, the limiting block 31 moves towards... Figure 5 The device moves to the left and eventually positions the fixing block 33 at the bottom of the limiting block 31. During this process, the third inclined surface 45 will abut against the limiting strip. Since the position of the limiting strip is fixed and cannot move, the positioning member 4 will be forced to move downward under the action of the limiting block 31, thereby causing the second elastic member 44 to produce greater elastic deformation and store greater elastic potential energy. At this time, the cover plate 23 continues to deflect towards the installation part 21 under the manual control of the operator. The limiting block 31 moves further in the limiting groove 32, eventually positioning the fixing block 33 at the bottom of the limiting strip. At this time, the second elastic member 44 releases elastic potential energy, and the second inclined surface 43 abuts against the first inclined surface 42. Similarly, since the elastic modulus of the second elastic member 44 is greater than that of the first elastic member 34, the position of the limiting block 31 in the limiting groove 32 is limited and will not move to the right. At this time, the position of the cover plate 23 is deflected into place, completing the installation of the cover plate 23.
[0039] When it is necessary to open the cover plate 23, the operator moves the positioning part 4 downwards, so that the positioning part 4 is disengaged from the limiting block 31. At this time, the limiting block 31 is disengaged from the limiting strip under the action of the first elastic part 34, and the cover plate 23 can be opened for fuel filling. The operation is simple and convenient.
[0040] Reference Figure 5 The bottom of the cover plate 23 is provided with a sliding groove 5, and a slider 51 is slidably arranged in the sliding groove 5. The bottom of the slider 51 is fixedly connected to the top of the limiting block 31. The first elastic element 34 is arranged in the sliding groove 5. The first elastic element 34 is a compression spring. One end of the first elastic element 34 is fixedly connected to the inner wall of the sliding groove 5, and the other end is fixedly connected to the side wall of the slider 51.
[0041] In one embodiment of this utility model, reference is made to... Figure 6 The slide 5 is a T-shaped groove, and the slider 51 is a T-shaped block adapted to the slide 5. Ball bearings (not shown in the figure) are embedded on the side wall of the slider 51. The ball bearings are used to roll and contact with the inner wall of the slide 5.
[0042] Reference Figure 6 and Figure 7 A strip groove 6 is provided vertically on the side wall of the mounting part 21. A strip block 61 is slidably disposed in the strip groove 6. A sliding plate 62 is fixedly disposed on the side of the strip block 61 away from the strip groove 6. The top of the sliding plate 62 is fixedly connected to the end of the positioning member 4 away from the limiting block 31. A second elastic member 44 is disposed in the strip groove 6. The second elastic member 44 is configured as a compression spring. One end of the second elastic member 44 is fixedly connected to the side wall of the strip block 61, and the other end is fixedly connected to the inner wall of the strip groove 6.
[0043] Reference Figure 7 Anti-slip texture 63 is fixedly provided on the side wall of the slide plate 62 away from the mounting part 21. The anti-slip texture 63 is made of silicone rubber, which has good anti-corrosion and anti-slip effects.
[0044] As one embodiment of this application, in actual use, this application can balance the gas pressure inside and outside the fuel tank and improve refueling efficiency. On the other hand, it can also prevent a large amount of gas inside the fuel tank from being emitted into the air during refueling. Compared with the traditional structure, it is more environmentally friendly during refueling and has significant environmental benefits.
[0045] The implementation principle of the yacht fuel tank structure proposed in this embodiment is as follows:
[0046] By opening a vent hole 24 on the side wall of the fuel filler pipe 22 and connecting it to a vent pipe 25, efficient exchange of gases inside and outside the fuel tank is achieved during refueling. When fuel is rapidly injected, the air inside the fuel tank is smoothly discharged through the vent pipe 25, effectively balancing the internal and external pressures. This avoids rapid gasoline evaporation to a certain extent, reduces gasoline evaporation in a short period of time, and thus improves environmental benefits. At the same time, it avoids the problem of reduced refueling speed caused by air resistance in traditional designs, ensuring continuous and rapid fuel filling, significantly shortening refueling time, and further shortening the time window for gasoline evaporation. This not only improves environmental benefits but also enhances the yacht's endurance preparation efficiency to a certain extent, making it particularly suitable for long-distance voyages or frequent refueling scenarios, thereby optimizing the overall energy replenishment process.
