[0031] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0032] Embodiment 1

[0033] In order to solve the problem that methanol in the existing methanol fuel tank will precipitate and stratify after standing in the fuel tank for a long time, affecting the supply stability and combustion efficiency of the fuel, please refer to Figures 1 - 3, the fuel tank of the methanol engine provided by the present utility model includes a fuel tank body 1 and a mounting plate 2 located at the upper end inside the fuel tank body 1. The mounting plate 2 is provided with at least two circles of strip-shaped through holes 201 evenly distributed along the circumference. A sliding member 6 is arranged in the strip-shaped through hole 201, and a vibrating rod 3 with its bottom end extending to the bottom surface of the fuel tank body 1 is fixedly arranged through the sliding member 6. A center of the mounting plate 2 is fixedly provided with an ultrasonic generator 4 for driving a plurality of vibrating rods 3 to vibrate at a high frequency. A transmission member 5 for transmitting vibration is arranged between the top of the ultrasonic generator 4 and the top end of the vibrating rod 3. The transmission member 5 can be a pull rope or other objects that can achieve the effect of vibration transmission. The ultrasonic generator 4 can drive a plurality of transmission members 5 to vibrate, and the transmission member 5 then transmits the vibration to the corresponding vibrating rod 3. The methanol fuel can be kept in a uniform mixing state all the time through the vibrating rod 3 vibrating at a high frequency, avoiding precipitation and stratification. Moreover, it can also promote the natural circulation flow of the methanol fuel in the tank, help to maintain the uniformity of the fuel, make the temperature distribution in the tank more uniform, reduce the situation of local overheating or overcooling, and reduce the risk of chemical reaction or deterioration of methanol.

[0034] As Figure 4 shown, a vibration output end 401 for providing a vibration source for the transmission member 5 is arranged at the top of the ultrasonic generator 4. The outer shape of the vibration output end 401 can be presented as a cylindrical convex structure. An ultrasonic emission end 402 for measuring the height of the methanol liquid level in the fuel tank body 1 is arranged at the bottom of the ultrasonic generator 4. The ultrasonic emission end 402 and the vibration output end 401 are integrated on the same ultrasonic generator 4, so that the ultrasonic generator 4 has both the functions of vibration drive and liquid level measurement, reducing the complexity and occupied space of the equipment.

[0035] In order to enhance the vibration of the transmission member 5 and optimize the vibration transmission efficiency for more effectively transmitting vibration, as Figure 3 and Figure 7 shown, at least one resonance component 8 for enhancing vibration transmission is arranged below the transmission member 5. The resonance component 8 includes a base 801 fixed on the top of the mounting plate 2. Two metal sheets 802 distributed on both sides of the transmission member 5 are arranged in a top groove of the base 801. A second spring 803 is arranged between the metal sheet 802 and the inner wall of the groove. Both of the two metal sheets 802 tightly abut against the transmission member 5 through the second spring 803. When the transmission member 5 vibrates, the second spring 803 will generate a telescopic movement according to its own elastic characteristics, thereby providing an additional resilience force for the transmission member 5. This resilience force interacts with the driving force of the ultrasonic wave to enhance the vibration amplitude and frequency stability of the transmission member 5.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, in order to solve the problem that in the long-term use process of the existing methanol fuel tank, impurities, sediments or viscous substances generated by methanol oxidation will gradually accumulate on the inner wall. The attachments will not only affect the effective volume of the methanol fuel tank, but also easily cause methanol pollution or deterioration problems. As Figure 3 shown, a first driving mechanism 7 for driving a plurality of vibrating rods 3 to move radially along the mounting plate 2 is further provided at the top of the ultrasonic generator 4, so that the outermost vibrating rod 3 moves to the inner wall of the fuel tank body 1 and vibrates to remove the substances attached to the inner wall.

[0038] As Figures 4 - 5 shown, the sliding member 6 includes a slider 601 slidably disposed in the strip-shaped through hole 201 and an elastic block 602 fixedly penetrating through the slider 601; the vibrating rod 3 is fixedly penetrated through the elastic block 602, and a movable rod 603 movably inserted into the mounting plate 2 is fixedly provided at one end of the slider 601, and a first spring 604 is sleeved on the movable rod 603. When the first driving mechanism 7 is released, under the reset force of the first spring 604, the slider 601 moves along the strip-shaped through hole 201 towards the inner wall of the fuel tank body 1 until the vibrating rod 3 abuts against the inner wall of the fuel tank body 1. The vibrating rod 3 vibrates at a high frequency driven by the ultrasonic generator 4, effectively reducing the adhesion force between the sediment and the inner wall, so as to more easily scrape off the sediment on the inner wall.

[0039] An elastic sealing sleeve 202 for closing the strip-shaped through hole 201 is provided at the bottom of the mounting plate 2. To prevent methanol volatilized gas from affecting the components above the mounting plate 2.

[0040] As Figure 6 shown, the first driving mechanism 7 includes a gear ring 701 rotatably disposed on the top of the ultrasonic generator 4 and four uniformly distributed support columns 702 fixed on the top of the gear ring 701; a circular plate 703 is fixedly provided at the top ends of the four support columns 702, and a circular hole 703a for the transmission member 5 to pass through is provided on the circular plate 703, and a plurality of rollers 703b uniformly distributed along the circumference are provided at the edge of the circular hole 703a; a rack 704 meshing with the gear ring 701 is provided on the side of the gear ring 701, and an electric push rod 705 for driving its movement is provided at the end of the rack 704. During use, the electric push rod 705 drives the rack 704 to move, the rack 704 drives the gear ring 701 to rotate, the gear ring 701 drives the support columns 702 to rotate, the support columns 702 drive the circular plate 703 to rotate, the circular plate 703 drives the transmission member 5 to twist, and the transmission member 5 drives the vibrating rod 3 and the sliding member 6 to slide along the strip-shaped through hole 201, so that the position of the vibrating rod 3 in the fuel tank body 1 can be adjusted. Based on needs, such as when the fuel tank body 1 needs to be cleaned, the vibrating rod 3 can be adjusted to the inner wall of the fuel tank body 1 to vibrate and clean the sediment on the inner wall.

[0041] In order to enable all parts of the inner wall of the fuel tank 1 to be processed by the vibrating rod 3 and scrape off the deposits through the vibrating rod 3, such as Figures 1 - 2 As shown, a ring body 101 for supporting the rotation of the mounting plate 2 is provided at the upper end inside the fuel tank 1; a fixing plate 102 is fixedly provided on the inner wall of the fuel tank 1 above the ring body 101, and a second driving mechanism 10 for driving the mounting plate 2 to rotate is provided on the fixing plate 102. The second driving mechanism 10 includes a motor 1001 and a connecting frame 1002 fixed on the output shaft of the motor 1001.

The motor 1001 drives the connecting frame 1002 to rotate, the connecting frame 1002 drives the mounting plate 2 to rotate along the ring body 101, and the mounting plate 2 drives the vibrating rod 3 thereon to rotate, vibrating all parts of the inner wall of the fuel tank 1 and scraping off the deposits.

[0042] Embodiment III

[0043] On the basis of Embodiment I and Embodiment II, in order to further improve the cleaning effect of the deposits on the inner wall of the fuel tank 1, such as Figure 8 As shown, elastic scraping strips 301 for scraping off the substances attached to the inner wall of the fuel tank 1 and water spraying holes 302 for flushing are respectively provided on the outermost vibrating rods 3; a flushing pipe fitting 9 for supplying flushing water is provided above the vibrating rods 3. The flushing pipe fitting 9 includes an annular pipe 901 fixed to the bottom of the fixing plate 102, and a connecting hose 902 for connecting the two is provided between the top end of the annular pipe 901 and the vibrating rod 3. External flushing water enters the annular pipe 901, is distributed to each connecting hose 902 through the annular pipe 901, then is transported to the inner cavity of the vibrating rod 3 through the connecting hose 902, and finally sprays out from the water spraying holes 302; ultrasonic vibration can help remove the deposits on the inner wall, and the high-pressure water column spraying can effectively clean. Combining the advantages of vibration and spraying helps to keep the fuel tank 1 clean. The scraping function of the elastic scraping strips 301 and the cleaning function of the water spraying holes 302 can timely remove the substances that may cause corrosion on the inner wall, such as moisture, impurities, and corrosive chemical substances, etc., further enhancing the corrosion resistance of the inner wall of the fuel tank 1.

[0044] An electric heating wire for heating methanol fuel is also provided inside the vibrating rod 3. To maintain a suitable storage environment inside the fuel tank 1, avoid the influence of too high or too low temperature on the quality of methanol fuel, and integrating the electric heating wire inside the vibrating rod 3 can greatly improve the heating uniformity and efficiency.
