The working principle is as follows: when the device is used and crude oil after testing needs to be collected, the crude oil is poured into the tapered hole 1, the crude oil in the tapered hole 1 passes through the filter screen 2 to extrude the sealing gasket 4 and the plugging plate 3, the plugging plate 3 moves downwards due to the extrusion force, the tension spring 11 is stretched when the plugging plate 3 rotates, the plugging plate 3 drives the sealing gasket 4 to rotate downwards, the plugging of the tapered hole 1 is removed when the sealing gasket 4 rotates, at the moment, the crude oil passing through the filter screen 2 enters the sampling box 100, when crude oil completely enters, the impact force on the plugging plate 3 disappears, at the moment, the elasticity of the tension spring 11 in the stretching state drives the plugging plate 3 to rotate upwards for resetting, the plugging plate 3 drives the sealing gasket 4 to rotate upwards for resetting to automatically plug the tapered hole 1, therefore, the purpose of automatically and timely plugging the tapered hole 1 after crude oil is poured is achieved, and the phenomena of crude oil splashing and odor overflowing are reduced;

if the impact force of petroleum on the plugging plate 3 is small, the plugging plate 3 cannot be driven to rotate downwards, at the moment, crude oil can be poured in, simultaneously, the push rod 8 is manually pressed downwards, the push rod 8 drives the extrusion rod 6 to move downwards, the push rod 8 moves downwards and simultaneously compresses the first spring 7, the extrusion rod 6 drives the extrusion roller to extrude the plugging plate 3 downwards, the extrusion force enables the plugging plate 3 to rotate downwards, the plugging plate 3 drives the sealing gasket 4 to rotate downwards to remove plugging of the tapered hole 1, crude oil in the tapered hole 1 enters the sampling box 100, after the crude oil completely enters, the pressing force on the push rod 8 can be released, at the moment, the elastic force of the first spring 7 in a compressed state drives the extrusion rod 6 to move upwards through the push rod 8, the extrusion rod 6 drives the extrusion roller to release the extrusion force on the plugging plate 3 upwards, at the moment, the elastic force of the tension spring 11 drives the plugging plate 3 to automatically return upwards to plug the tapered hole 1, by manually extruding the plugging plate 3, the phenomenon that the plugging plate 3 cannot rotate downwards due to the impact force of crude oil can be effectively avoided, and the stability of crude oil sample collection is improved;

when the plugging device is used for a long time, the phenomenon that the elastic fatigue elasticity of the tension spring 11 is weakened can be caused, and then the plugging stability of the tapered hole 1 is influenced, when the elasticity of the tension spring 11 needs to be adjusted, the forward rotation knob drives the screw rod 15 to rotate, under the effect of the threaded hole formed in the rectangular block 14, the screw rod 15 rotates to drive the rectangular block 14 to move upwards, the rectangular block 14 drives the moving block 10 to slide upwards in the first rectangular groove 9 through the moving rod 12, the moving block 10 upwards stretches the tension spring 11, and the part with the weakened elastic fatigue elasticity of the tension spring 11 can be offset in a mode of adjusting the stretching degree of the tension spring 11, so that the elasticity of the tension spring 11 can be improved, and further the stability of rotary plugging of the plugging plate 3 is improved.
