Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-4The utility model provides a technical solution: a fuel tank anti-wave plate structure, including a fuel tank anti-wave plate structure main body 1, a mounting plate 2 is arranged on the fuel tank anti-wave plate structure main body 1, and the mounting plate 2 is a bent part, the two sides of the mounting plate 2 are bent to form a bent positioning plate 203, and the bottom of the mounting plate 2 is bent to form a bent support plate 205, the mounting plate 2 and the bent positioning plate 203 and the bent support plate 205 all form an L-shaped structure, and the bending parts of the mounting plate 2 and the bent support plate 205 are also provided with a second weight-reducing hole 206, and the bent support plate 205 is provided with a circular hole, the second weight-reducing hole 206 of this structure also reduces the weight of the mounting plate 2, the bent support plate 205 is supported at the bottom of the fuel tank, and the bent support plate 205 can be screwed with the fuel tank through the circular hole The first wave-breaking plate 6 and the second wave-breaking plate 7 are fixed by bolts, and the bent support plate 205 can also be welded and fixed to the oil tank. Since the first wave-breaking plate 6 and the second wave-breaking plate 7 are installed and positioned by the guide column 3, the installation method is simple, so that the oil tank wave-breaking plate structure main body 1 can be quickly assembled in the oil tank. Two second mounting holes 204 are provided on the bent positioning plate 203, and the second mounting holes 204 are distributed longitudinally, and the second mounting holes 204 correspond to the positions of the guide columns 3 at both ends respectively. The second mounting holes 204 of this structure are used in the same way as the first mounting holes 202. The guide columns 3 fixed on the bent positioning plate 203 are positioned through the second mounting holes 204 to ensure the stable installation of the second wave-breaking plates 7 at both ends. Since the mounting plate 2 and the bent positioning plate 203 form an L-shaped structure, the first wave-breaking plate 204 can be fixed to the oil tank by the guide column 3 fixed on the bent positioning plate 203. The wave plate 6 and the second wave-breaking plate 7 are perpendicular to each other, and can perform wave-breaking treatment on oil waves caused by bumps in different directions to achieve the purpose of noise reduction. First wave-breaking plates 6 are respectively provided on both sides of the mounting plate 2, and second wave-breaking plates 7 are respectively provided at both ends of the mounting plate 2. Through holes are provided on the first wave-breaking plate 6 and the second wave-breaking plate 7, and guide columns 3 are respectively penetrated in the first wave-breaking plate 6 and the second wave-breaking plate 7. A first weight-reducing hole 201 and a first mounting hole 202 are provided on the mounting plate 2, and three first mounting holes 202 are provided. The first mounting holes 202 are arranged horizontally, and the first mounting holes 202 correspond to the positions of the guide columns 3 on both sides, respectively. This structure enables the mounting plate 2 to perform large-area weight reduction treatment through the first weight-reducing hole 201, while ensuring the structural strength of the mounting plate 2 Under the circumstance, the weight of the mounting plate 2 is greatly reduced, and the first mounting hole 202 also reduces the weight of the mounting plate 2.

A compression spring 4 is respectively passed through the guide column 3. The limit end 301 plays a positioning role for the compression spring 4 at the outer end. Then, the first wave-breaking plate 6 and the second wave-breaking plate 7 are respectively passed through the guide column 3 through the ball guide sleeve 5. Then, a compression spring 4 is sleeved on the guide column 3, so that both sides of the first wave-breaking plate 6 and the second wave-breaking plate 7 have a compression spring 4. Then, the guide column 3 is passed through the first mounting hole 202 and the second mounting hole 203.
