[0029] A frame assembly 2 is mounted on the fuel tank 1;
[0030] A drive assembly 3 is mounted on the frame assembly 2, the drive assembly 3 comprises four rotating shafts 31, two sprockets 32 are mounted on each rotating shaft 31, eight sprockets 32 are evenly divided into two groups and symmetrically arranged at positions close to both ends of the rotating shaft 31, a chain 33 is arranged between each group of sprockets 32, and the chain 33 has a mouth-shaped structure;
[0031] An anti-wave assembly 4 is provided in multiple numbers and is equally spaced between the two chains 33, the anti-wave assembly 4 comprises an anti-wave plate 41, a plurality of flow guide holes 42 are provided through the anti-wave plate 41, a rod sleeve 43 is mounted on both sides of the anti-wave plate 41, a shaft rod 44 is rotatably arranged inside the rod sleeve 43, a connecting block 45 is mounted at both ends of the shaft rod 44, and the connecting block 45 is fixedly connected with the chain 33.
[0032] Specifically, a plurality of anti-wave plates 41 are equally distributed between the chains 33, when the chains 33 move, since the connecting block 45 fixes the shaft rod 44 with the chain 33 and the shaft rod 44 can rotate in the rod sleeve 43, the movement of the chain 33 can be smoothly converted into the up-down movement of the anti-wave plate 41, the flow guide holes 42 on the anti-wave plate 41 can reduce the flow resistance of the fuel while playing a certain buffering and dispersing role on the fuel surge, through this connection mode and structural design, the anti-wave plate 41 can be flexibly adjusted in height in the fuel tank 1 according to the different positions of the chain 33, that is, according to the driving condition of the drive assembly 3, so as to adapt to the requirements of the anti-wave effect under different fuel quantities, effectively suppress the fuel surge phenomenon, and ensure the stable operation of the fuel tank.
[0033] Figures 1-6 The second embodiment is shown, the main difference from the first embodiment is that the frame assembly 2 comprises a mounting plate 21, and the mounting plate 21 is detachably connected with the fuel tank 1 by bolts, the bottom surface of the mounting plate 21 is symmetrically provided with side plates 22, and the side plates 22 can be placed inside the fuel tank 1 through the mounting hole 11.
[0034] Specifically, the mounting plate 21 is detachably connected with the fuel tank 1 by bolts, which facilitates the installation, maintenance and replacement of the entire adjusting mechanism on the fuel tank 1.
[0035] In this embodiment, two limiting plates 24 are mounted on the opposite side surfaces of the two side plates 22, for maintaining the stability of the chain 33.
[0036] Specifically, the limiting plate 24 limits the chain 33 laterally during the movement of the chain 33, effectively constrains the movement track of the chain 33, and makes the chain 33 always run within the predetermined range, avoiding abnormal conditions such as the chain 33 escaping from the sprocket 32 or colliding with other components, winding, etc., thereby ensuring the stability of the wave prevention assembly 4.
[0037] In the embodiment, a plurality of crossbars 23 are installed between the opposite side surfaces of the two side plates 22 near the bottom, for maintaining the stability of the structure of the two side plates 22.
[0038] Specifically, the crossbars 23 are connected between the two side plates 22, enhancing the overall structural strength of the side plates 22.
[0039] In the embodiment, the driving assembly 3 further comprises a motor 35 installed on the top surface of the mounting plate 21. The output shaft end of the motor 35 is movably penetrated through the top surface of the mounting plate 21 and extends downward. The end of the rotating shaft 31 is rotatably arranged on the side plate 22. The output shaft end of the motor 35 is provided with a second bevel gear 36. The first bevel gear 34 is engagedly connected to the second bevel gear 36, and the first bevel gear 34 is fixedly sleeved on the outer wall of one of the rotating shafts 31.
[0040] Specifically, the second bevel gear 36 at the output shaft end of the motor 35 is engagedly connected to the first bevel gear 34, realizing the steering and transmission of the power of the motor 35, so that the rotating shaft 31 can stably rotate under the support of the side plate 22, thereby driving the movement of the sprocket 32 and the chain 33.
[0041] Meanwhile, the contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.
[0042] When the height-adjustable built-in fuel tank wave plate is working, the motor 35 is started. The second bevel gear 36 at the output shaft end of the motor 35 drives the first bevel gear 34 engaged therewith to rotate, thereby making the rotating shaft 31 fixedly sleeved therewith rotate. When the rotating shaft 31 rotates, the sprocket 32 drives the chain 33 to move. Thus, during the movement of the chain 33, the wave plate 41 can rise or fall with the chain 33, realizing height adjustment to adapt to the requirements of different fuel quantities on the wave prevention effect and effectively suppressing the fuel surge phenomenon.
