Description

Technical Field

[0001] The present invention relates to the technical field of fuel quality detection, and in particular to a device for detecting the quality of automobile fuel. Background Art

[0002] Fuel quality testing is an important part of ensuring engine performance and vehicle safety. High-quality gasoline should be colorless or light yellow, clear and transparent. If the color is too dark or turbid, it may mean that the fuel contains impurities or other undesirable components. Normal fuel should have a slight gasoline smell. If it has a pungent or unpleasant odor, it may be of poor quality. If a small amount of gasoline is left for a period of time and there is no color change, it means the quality is stable. Conversely, blackening may mean that the oil has deteriorated. It is usually not convenient to directly observe the fuel stored in the fuel tank. When the tank pipe mouth is directly opened to take a sample, a large amount of air can easily enter the tank. If static electricity occurs, combustion is likely to occur, which is not conducive to the safe detection of the fuel. In addition, it is not convenient to sample fuel at different depths when sampling the fuel, resulting in inaccurate sampling results. For this reason, a kind of automotive fuel quality testing equipment is needed. Summary of the Invention

[0040] like Figure 4-Figure 7 As shown, a liquid suction shell 310 is provided in the float 30, and the liquid suction shell 310 is close to the bottom of the float 30. There are multiple liquid suction shells 310 and they are evenly spaced along the length direction of the float 30. The wall of the liquid suction shell 310 is connected to the liquid inlet pipe 320, and the end of the liquid inlet pipe 320 passes through the wall of the float 30. A pump body is provided in the liquid suction shell 310. When the quality of the fuel in the oil tank is tested, the sealing plate 10 is placed in the pipe mouth of the oil tank, and then the sealing plate 10 is pressed.

When the fuel tank 22 is lowered, ...

[0041] like Figure 6-Figure 8 As shown, the wall of the float 30 is provided with a push rod 1 330 and a push rod 2 340, and the push rod 1 330 and the push rod 2 340 are arranged opposite to each other, and the installation method of the push rod 1 330 and the push rod 2 340 is the same. The top of the blocking plate 10 is vertically provided with a vertical plate 130 and a vertical plate 2 140, and the vertical plate 130 and the vertical plate 2 140 are arranged opposite to each other.

A tooth block 2 141 is provided on the plate surface of the vertical plate 2 140, and a plurality of tooth blocks 141 are provided and are evenly spaced along the length direction of the vertical plate 2 140. The tooth blocks 131 and the tooth blocks 2 141 are staggered.

[0042] More specifically, a mounting plate 341 is provided on the wall of the float 30, and the push rod 2 340 is rotatably connected to the mounting plate 341 through the connecting shaft 342. A connecting rod 343 is fixedly provided on the circumference of the connecting shaft 342. A limiting rod 1 344 and a limiting rod 2 345 are fixed vertically on the wall of the mounting plate 341. The limiting rod 1 344 is located just above and close to the connecting shaft 342, and the limiting rod 2 345 is located on one side of the connecting shaft 342. In the initial state, the connecting rod 343 contacts the limiting rod 2 345, pressing the float 30 and moving the float 30 The lower section is placed below the fuel liquid level. During the downward movement of the float 30, the end of the push rod 1 330 touches the end surface of the gear block 1 131, and the end of the push rod 2 340 touches the end surface of the gear block 2 141, thereby driving the push rod 1 330 and the push rod 2 340 to deflect. When the fuel liquid is taken out, the float 30 is lifted. During the upward movement of the float 30, the ends of the push rod 1 330 and the push rod 2 340 respectively contact the lower end surfaces of the gear block 1 131 and the gear block 2 141, thereby driving the float 30 to swing left and right, thereby causing the float 30 to shake and shake off the fuel on the wall of the float 30.

[0043] like Figure 6 As shown, a storage shell 160 is provided at the bottom of the baffle plate 10, and a breathable plate 161 is matched at the bottom of the storage shell 160. A deoxidizer is stored in the storage shell 160.

[0044] like Figure 2 As shown, a handle 110 is provided on the top of the blocking plate 10 to facilitate pressing the blocking plate 10 into the pipe mouth of the oil tank.

[0045] Working principle:

[0046] During use of the present invention, when the quality of the fuel in the oil tank is inspected, the blocking plate 10 is placed in the nozzle of the oil tank, and then the blocking plate 10 is pressed. The airbag 120 on the outer periphery of the blocking plate 10 contacts the inner wall of the nozzle of the oil tank, thereby blocking the nozzle of the oil tank. When the airbag 120 contacts the inner wall of the nozzle of the oil tank, the airbag 120 is squeezed, and the gas in the airbag 120 pushes the trigger block 227 to move upward, thereby driving the guide plate 228 to move upward. Then the guide plate 228 drives the push plate 225 to move away from the support plate 221, thereby driving the push plate 1 223 to move towards the support plate 221. The top column 224 cancels the clamping of the float 30, and then the float 30 moves down. The bottom of the float 30 contacts the fuel liquid surface and floats on the fuel liquid surface. At this time, the downward movement of the float 30 is recorded, and then the float 30 is pressed. The liquid extraction depth of the liquid suction housing 310 can be determined according to the pressing amount. When the fuel tank is fully filled, the fuel tank 310 is lifted up and the fuel tank 310 is in a state of being lifted and discharged.
