Description
Technical Field
[0001] The invention relates to the technical field of fuel quality detection, and in particular to a vehicle fuel quality detection device. 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 there is a pungent, 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 that the quality is stable. On the contrary, blackening may mean that the oil is deteriorating. It is usually not convenient to directly observe the fuel stored in the fuel tank. When the tank pipe mouth is directly opened for sampling, a large amount of air is easy to enter the tank. If static electricity occurs, combustion is easy to occur, which is not conducive to the safe detection of fuel. In addition, when sampling the fuel, it is not convenient to sample fuel at different depths, resulting in inaccurate sampling results.

The top column 224 is vertically arranged on the plate surface of the push plate 1 223, and the end of the top column 224 contacts the wall of the float 30.
[0030] More specifically, an escape opening is provided at the top of the accommodating groove 150 of the blocking plate 10, and a trigger block 227 is matched and arranged at the escape opening of the accommodating groove 150.

[0031] 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. The liquid suction shell 310 is provided with multiple and evenly spaced along the length direction of the float 30. The wall of the liquid suction shell 310 is connected with a 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. The air bag 120 on the outer periphery of the sealing plate 10 contacts the inner wall of the pipe mouth of the oil tank, thereby blocking the pipe mouth of the oil tank. The air bag 120 contacts the inner wall of the pipe mouth of the oil tank. When the airbag 120 is squeezed, the gas in the airbag 120 pushes the trigger block 227 to move upward, thereby driving the guide plate 228 to move upward, and 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 toward the support plate 221, and the top column 224 cancels the clamping of the float 30, and then the float 30 moves downward, and 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 shell 310 can be determined according to the pressing amount, and then the pump body is opened, and the liquid suction shell 310 absorbs the fuel.
[0032] 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 relatively to each other, and the installation method of the push rod 1 330 and the push rod 2 340 is the same, and the top of the sealing 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 relatively to each other, and a tooth block 131 is provided on the plate surface of the vertical plate 130, and a plurality of tooth blocks 131 are provided and are evenly spaced along the length direction of the vertical plate 130, and 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, and the tooth blocks 131 and the tooth blocks 2 141 are staggered.
[0033] More specifically, a mounting plate 341 is provided on the wall of the floating body 30, and the push rod 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 344 and a limiting rod 345 are vertically fixedly provided on the wall of the mounting plate 341. The limiting rod 344 is located directly above and close to the connecting shaft 342, and the limiting rod 345 is located on one side of the connecting shaft 342. In the initial state, the connecting rod 343 contacts the limiting rod 345, pressing the floating body 30 and moving the floating body 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 tooth block 1 131, and the end of the push rod 2 340 touches the end surface of the tooth 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 tooth block 1 131 and the tooth block 2 141, thereby driving the float 30 to swing left and right, thereby shaking the float 30 and shaking off the fuel on the wall of the float 30.
[0034] like Figure 6 As shown, a storage shell 160 is provided at the bottom of the sealing 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. When the sealing plate 10 is placed in the pipe mouth of the oil tank, the deoxidizer in the storage shell 160 can remove the oxygen in the oil tank, thereby reducing the risk of fuel combustion and improving the safety of fuel quality detection.
[0035] like Figure 2 As shown, a handle 110 is provided on the top of the sealing plate 10 to facilitate pressing the sealing plate 10 into the pipe opening of the oil tank.
[0036] Working principle: 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 pipe mouth of the oil tank, and then the blocking plate 10 is pressed, and the airbag 120 on the outer periphery of the blocking plate 10 contacts the inner wall of the pipe mouth of the oil tank, thereby blocking the pipe mouth of the oil tank. When the airbag 120 contacts the inner wall of the pipe mouth 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 toward the support plate 221, and the top column 224 cancels the clamping of the float 30, and then the float 30 moves downward, and 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 pump body is opened, the suction shell 310 sucks the fuel, presses the float 30 and places the lower section of the float 30 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 tooth block 1 131, and the end of the push rod 2 340 touches the end surface of the tooth block 2 141, thereby driving the push rod 1 330 and the push rod 2 340 to deflect. When the fuel liquid is taken, 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 tooth block 1 131 and the tooth block 2 141, thereby driving the float 30 to swing left and right, thereby making the float 30 shake and shake off the fuel on the wall of the float 30. When the sealing plate 10 is placed in the pipe mouth of the oil tank, the deoxidizer in the storage shell 160 can remove the oxygen in the oil tank, thereby reducing the risk of fuel combustion and improving the safety of fuel quality detection.
