In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] Embodiment 1

[0030] like Figure 1-8 As shown, a detection device for the liquid level of a methanol vehicle fuel tank includes a connecting component, wherein both upper and lower ends of the connecting component are fixed to the side of the fuel tank and are connected to the inside of the fuel tank, a magnetic float 19 is slidably connected inside the connecting component, a magnetic flip component is rotatably connected to the outside of the connecting component, and a plurality of magnetic flip columns 15 are rotatably connected inside the magnetic flip component, and the plurality of magnetic flip columns 15 are all magnetically connected to the magnetic float 19;

[0031] The working principle of the above technical solution is as follows: the interior of the fuel tank is connected with the interior of the connecting component, methanol is injected into the fuel tank, the methanol liquid level inside the fuel tank is level with the methanol liquid level in the connecting component, the methanol in the connecting component lifts the magnetic float 19, and as the methanol liquid level continues to rise, the magnetic float 19 continues to move upward in the connecting component, the magnetic float 19 is magnetically coupled with the magnetic flip column 15, driving the magnetic flip column 15 to flip, different colors are set on both sides of the magnetic flip column 15, and the rising position of the magnetic float 19 can be intuitively viewed after flipping, which corresponds to the position of the connecting component and the methanol liquid level in the fuel tank. The connecting component is rotatably connected to the magnetic flip component, and the magnetic flip component can be rotated to change the direction facing the magnetic flip component, thereby adapting to different positions to view the position of the methanol liquid level through the flipping of the magnetic flip column 15.

[0032] Embodiment 2

[0033] like Figure 1-8 As shown, the fuel tank comprises a box body 1, a connecting pipe 2 is fixed on the side of the box body 1, a connecting elbow 9 is arranged on the box body 1, a ball valve 3 and a ball valve 10 are arranged in the connecting pipe 2 and the connecting elbow 9 respectively, and the connecting pipe 2 and the connecting elbow 9 are fixedly connected to the connecting component;

[0034] The working principle of the above technical solution is as follows: methanol is added into the tank body 1, and the methanol in the tank body 1 enters the connecting component through the connecting pipe 2. The gas space above the tank body 1 without methanol is connected to the gas space above the connecting component through the connecting elbow 9, so that the air pressure above the tank body 1 is the same as the air pressure above the connecting component. The connecting elbow 9 is located at the upper end of the tank body 1 to prevent methanol from entering the connecting elbow 9, and isolates the gas space above the tank body 1 from the gas space above the connecting component, resulting in the formation of a sealed space in the gas space above the connecting component, and the liquid level in the connecting component cannot rise, resulting in the methanol liquid level in the tank body 1 and the methanol liquid level in the connecting component cannot be level, thereby affecting the accuracy of methanol level detection in the tank body 1.

[0035] Embodiment 3

[0036] like Figure 1-8As shown, the connecting component includes a detection tube 5, the upper end of the detection tube 5 is fixedly connected to the connecting elbow 9 through a connecting tube 3 8, and the lower end of the detection tube 5 is fixed to the connecting tube 1 2 through a connecting tube 2 4, and the axis of the connecting tube 1 2 and the connecting tube 2 4 is higher near the side of the box body 1 than near the side of the detection tube 5;

[0037] The working principle of the above technical solution is: methanol is added into the box body 1, and the methanol in the box body 1 enters the detection tube 5 through the connecting tube 1 2 and the connecting tube 2 4. The gas space above the box body 1 without methanol is connected with the gas space above the connecting component through the connecting tube 3 8 and the connecting elbow 9, so that the air pressure above the box body 1 is the same as the air pressure above the connecting component. The connecting tube 1 2 and the connecting tube 2 4 form a combined tube. The combined tube is not in a horizontal state, and is lower on the side close to the box body 1. Because the combined tube is thin, it is easy to be blocked. If the combined tube is placed horizontally, methanol flows through the combined tube for a long time, and the sediment in the methanol is easy to accumulate in the combined tube, causing the combined tube to be blocked. The combined tube is placed at an angle, and the sediment inside it flows back to the box body 1, thereby reducing the risk of blockage of the combined tube.

[0038] Embodiment 4

[0039] like Figure 1-8 As shown, the outer sides of the connecting pipe 1 2, the connecting pipe 2 4, the connecting pipe 3 8 and the connecting elbow 9 are all provided with reinforcing ribs;

[0040] The working principle of the above technical solution: the reinforcing ribs can increase the strength of the connecting pipe 1 2, the connecting pipe 2 4, the connecting pipe 3 8 and the connecting elbow 9 to prevent the connecting pipe 1 2, the connecting pipe 2 4, the connecting pipe 3 8 and the connecting elbow 9 from being easily bent.

[0041] Embodiment 5

[0042] like Figure 1-8 As shown, a cleaning pipe 6 is provided at the lower side of the connecting pipe 2 4, a liquid outlet pipe 7 is provided at the lower end of the detection pipe 5, an air pipe 20 is provided at the upper end of the detection pipe 5, and valve bodies are provided in the cleaning pipe 6, the liquid outlet pipe 7 and the air pipe 20;

[0043] The working principle of the above technical solution is as follows: when there are impurities in the detection tube 5 that affect the magnetic measurement accuracy, close the ball valve 10, open the valve body in the air pipe 20, and add ammonia gas into the detection tube 5, so that the air pressure inside the detection tube 5 increases, and then squeeze the methanol inside the detection tube 5 to flow back into the box 1, so as to prevent the detection tube 5 from retaining methanol and causing methanol waste. After the methanol inside the detection tube 5 flows back into the box 1, close the ball valve 3, open the valve body in the cleaning tube 6, and inject cleaning liquid into the detection tube 5 through the cleaning tube 6 and the connecting tube 2 4, open the valve body in the liquid outlet pipe 7, and release the cleaning liquid and impurities from the liquid outlet pipe 7, so as to clean the impurities inside the detection tube 5 without removing the detection tube 5.

[0044] The valve body can be selected from a ball valve, a solenoid valve, and a butterfly valve.

[0045] Embodiment 6

[0046] like Figure 1-8 As shown, a support plate 12 is fixed at an upper position in the detection tube 5, and a plurality of through holes are provided on the support plate 12. A center column 13 and a spring 14 are fixed at the lower end of the support plate 12, and a magnetic float 19 is slidably connected to the center column 13;

[0047] A curved surface 21 is provided at a lower position inside the detection tube 5;

[0048] The working principle of the above technical solution is as follows: the methanol liquid level in the detection tube 5 rises, driving the magnetic float 19 to slide upward on the central column 13. The central column 13 limits the magnetic float 19 to prevent the magnetic float 19 from shaking randomly during the upward movement. After the magnetic float 19 moves up to a preset height, it returns to the spring 14, driving the spring 14 to compress. The spring 14 plays a buffering role to prevent the magnetic float 19 from hitting the support plate 12 and causing damage to the magnetic float 19. The multiple through holes provided on the support plate 12 can facilitate the gas in the detection tube 5 to communicate with the gas in the box 1.

[0049] When there is methanol in the box 1 , the magnetic float 19 moves down and gets stuck on the arc surface 21 under the action of gravity. When the methanol in the box 1 is emptied, the arc surface 21 facilitates the methanol in the detection tube 5 to flow down along the arc surface 21 , thereby reducing the residual methanol in the detection tube 5 .

[0050] Embodiment 7

[0051] like Figure 1-8 As shown, the magnetic flip component includes a shell 11, the shell 11 is rotatably connected to the outside of the detection tube 5, and multiple magnetic flip columns 15 are rotatably connected to the inside of the shell 11. A glass panel 16 is provided on the side of the shell 11, and scales 17 are provided on both sides of the glass panel 16;

[0052] The working principle of the above technical solution is: when the magnetic float 19 moves up or down in the detection tube 5, the magnetic flip column 15 closest to the magnetic float 19 will flip over, and the glass panel 16 can be used to check the flipping of the magnetic flip column 15. The scale 17 corresponds to the position of the flipped magnetic flip column 15, and then corresponds to the position scale of the methanol liquid level.

[0053] Embodiment 8

[0054] like Figure 1-8 As shown, two groups of magnetic isolation grooves 18 are provided in the housing 11, and the two groups of magnetic isolation grooves 18 are respectively located on both sides of the magnetic flip column 15, and the magnetic isolation grooves 18 are filled with magnetic isolation materials;

[0055] The working principle of the above technical solution is: the magnetic isolation groove 18 is filled with magnetic isolation material, which can reduce the interference of the external magnetic field on the magnetic flip column 15 and increase the accuracy of its detection. The magnetic isolation material is one of plastic, ceramic and wood.

[0056] Embodiment 9

[0057] like Figure 1-8 As shown, a toothed disc 22 is provided at the upper end of the housing 11, and the toothed disc 22 rotates outside the detection tube 5, and the toothed disc 22 is connected with a clamping block 23, and a limiting column 24 is fixed on the clamping block 23, and the clamping block 23 and the limiting column 24 are both slidably connected with a limiting shell 26, and a spring 25 is provided on the outer sleeve of the limiting column 24, and one end of the spring 25 is fixed on the clamping block 23, and the other end of the spring 25 is fixed on the limiting shell 26, and the limiting shell 26 is fixed on the detection tube 5;

[0058] The working principle of the above technical solution is: rotate the shell 11, the shell 11 and the detection tube 5 rotate, drive the toothed disc 22 to rotate with the shell 11, drive the block 23 and the limit column 24 to move up, drive the spring 25 to be compressed, and under the elastic force of the spring 25, the block 23 is stuck in another slot position of the toothed disc 22 until the shell 11 rotates to a preset position. The block 23 has a certain limiting effect on the toothed disc 22 to prevent the shell 11 from rotating automatically and arbitrarily. At this time, the direction of the glass panel 16 is changed, which is convenient for people in other directions to observe the flipping of the magnetic flip column 15 in the glass panel 16, and then determine the position of the methanol liquid level.

[0059] Embodiment 10

[0060] like Figure 1-8 As shown, a methanol vehicle comprises a methanol vehicle fuel tank liquid level detection device as described in any one of the above items.

[0061] The working principle of the above technical solution is: by detecting the methanol liquid level in the methanol vehicle through the methanol vehicle fuel tank liquid level detection device, the amount of methanol added in the methanol vehicle can be controlled to prevent excessive methanol filling and methanol overflow, resulting in methanol waste.
