[0020] 3. The present invention provides an elastic scraper, a water spray hole, a flushing pipe and a second driving mechanism. The sediments attached to the inner wall of the fuel tank body are subjected to ultrasonic high-frequency vibration, which effectively reduces the adhesion between the sediments and the inner wall. The sediments are then mechanically scraped off by the elastic scraper and flushed through the water spray hole to effectively remove the sediments, thereby increasing the effective volume of the methanol fuel tank and avoiding methanol contamination or deterioration.

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 vibration rod 3, and the vibration rod 3 with high frequency vibration keeps the methanol fuel in a uniform mixed state at all times, avoids the occurrence of precipitation and stratification, and can also promote the natural circulation of the methanol fuel in the tank, which helps to maintain the uniformity of the fuel, makes the temperature distribution in the tank more uniform, reduces the situation of local overheating or overcooling, and reduces the risk of chemical reaction or deterioration of methanol.

[0034] like Figure 4As shown, a vibration output terminal 401 for providing a vibration source to the transmission member 5 is provided at the top of the ultrasonic generator 4, and the shape of the vibration output terminal 401 can be presented as a cylindrical protruding structure; an ultrasonic transmitting terminal 402 for measuring the height of the methanol liquid level in the fuel tank 1 is provided at the bottom of the ultrasonic generator 4, and the ultrasonic transmitting terminal 402 and the vibration output terminal 401 are integrated on the same ultrasonic generator 4, so that the ultrasonic generator 4 has the functions of vibration driving and liquid level measurement at the same time, reducing the complexity of the equipment and the occupied space.

The first driving mechanism 7 can be released, and under the reset force of the first spring 604, the slider 601 moves along the strip-shaped through hole 201 toward the inner wall of the fuel tank body 1 until the vibration rod 3 contacts the inner wall of the fuel tank body 1, and the vibration rod 3 vibrates at a high frequency driven by the ultrasonic generator 4, effectively reducing the adhesion between the sediment and the inner wall, so that the sediment on the inner wall can be scraped off more easily.

[0039] The bottom of the mounting plate 2 is provided with an elastic sealing sleeve 202 for sealing the strip-shaped through hole 201 to prevent the methanol volatile gas from affecting the components above the mounting plate 2.

Based on needs, if the fuel tank body 1 needs to be cleaned, the vibration rod 3 can be adjusted to the inner wall of the fuel tank body 1 to vibrate and clean the deposits on the inner wall.

[0041] In order to ensure that all parts of the inner wall of the fuel tank 1 can be processed by the vibrating rod 3 and the deposits can be scraped off by the vibrating rod 3, Figure 1-Figure 2As shown, a ring body 101 for supporting the rotation of the mounting plate 2 is provided at the upper end of the inner part of the fuel tank body 1; a fixing plate 102 is fixedly provided on the inner wall of the fuel tank body 1 above the ring body 101, and a second driving mechanism 10 for driving the rotation of the mounting plate 2 is provided on the fixing plate 102, and the second driving mechanism 10 comprises a motor 1001 and a connecting frame 1002 fixed on the output shaft of the motor 1001, and the bottom of the connecting frame 1002 is fixedly connected to the mounting plate 2. The motor 1001 drives the connecting frame 1002 to rotate, and the connecting frame 1002 drives the mounting plate 2 to rotate along the ring body 101, and the mounting plate 2 drives the vibration rod 3 thereon to rotate, so as to vibrate various parts of the inner wall of the fuel tank body 1 and scrape off the sediment.

[0042] Embodiment 3

Figure 8 As shown, the outermost vibration rod 3 is provided with an elastic scraper 301 for scraping off the material attached to the inner wall of the fuel tank 1 and a water spray hole 302 for flushing; a flushing pipe 9 for supplying flushing water is provided above the vibration rod 3, and the flushing pipe 9 includes an annular pipe 901 fixed at the bottom of the fixing plate 102, and a connecting hose 902 for connecting the annular pipe 901 and the top of the vibration rod 3 is provided. The external flushing water enters the annular pipe 901, is distributed to each connecting hose 902 through the annular pipe 901, and then is transported to the internal cavity of the vibration rod 3 through the connecting hose 902, and finally sprayed out from the water spray hole 302; ultrasonic vibration can help remove the sediment on the inner wall, and the high-pressure water column spray can effectively clean it. Combining the advantages of vibration and spraying, it helps to keep the fuel tank 1 clean. The scraping function of the elastic scraper 301 and the cleaning function of the water spray hole 302 can timely remove the materials on the inner wall that may cause corrosion, such as moisture, impurities and corrosive chemicals, and further enhance the corrosion resistance of the inner wall of the fuel tank 1.
