Specific embodiments

[0023] Referring to Figures 1 to 9 a pollution - prevention sampling device for an oil storage tank shown, which includes a closing component 1. A closing plate 109 is provided on the closing component 1. The closing component 1 mounts the closing plate 109 on the base 101 to ensure the sealing of the oil tank. At the same time, a first pressing column 103 and a second pressing column 104 are provided on the closing component 1. The second pressing column 104 ensures that the rotating block 105 will not loosen during transportation, ensuring the sealing of the oil tank. A sampling component 2 is detachably provided on the base 101. The sampling component 2 samples the oil liquid in the oil tank, and a filter box 202 is provided on the sampling component 2. The sampling component 2 recovers and treats the oil and gas leaked during sampling through the filter box 202.

[0024] The closed component 1 includes a base 101. A locking column 102 is rotatably arranged on one side of the base 101. Threads are provided on the locking column 102. A rotating block 105 is slidably arranged on the locking column 102. The rotating block 105 is threadedly connected to the locking column 102. When the rotating block 105 is rotated, the rotating block 105 slides on the locking column 102. One end of the locking column 102 away from the base 101 is provided with a first pressing column 103. A second pressing column 104 is slidably arranged in the first pressing column 103. A third spring is arranged between the first pressing column 103 and the second pressing column 104. A pressing disc 110 is arranged on the second pressing column 104. The pressing disc 110 is rotatably connected to the rotating block 105. A pressing rod 106 is rotatably arranged at the other end of the base 101. A pressing groove 108 is arranged at one end of the pressing rod 106. A foot pedal disc 107 is arranged at the other end of the pressing rod 106. A closing disc 109 is detachably arranged on the base 101. A top plate 111 is slidably arranged inside the closing disc 109. A first spring 112 is arranged between the top plate 111 and the base 101. The first spring 112 is rotatably connected to the pressing rod 106. When the pressing groove 108 is inserted into the locking column 102, the rotating block 105 is twisted to move, so that the rotating block 105 approaches the pressing groove 108 and presses the pressing groove 108. At this time, the third spring presses the second pressing column 104, and the second pressing column 104 drives the pressing disc 110 to press the rotating block 105, preventing the rotating block 105 from loosening during the transportation of the oil tank. When the pressing rod 106 is pressed, the pressing rod 106 drives the top plate 111 to move, and the top plate 111 presses the first spring 112. At this time, the fixing of the closing disc 109 is completed. When it is necessary to open the closing disc 109, the rotating block 105 is twisted to reset, and then the locking column 102 is rotated to remove the locking column 102 from the pressing groove 108. The staff operates the foot pedal disc 107, and the foot pedal disc 107 drives the pressing rod 106 and the closing disc 109 to be removed from the base 101. At this time, the base 101 is opened, facilitating the sampling component 2 to sample the oil liquid in the oil tank.

[0025] The sampling assembly 2 includes a sampling housing 201. A set of clamping plates 203 are slidably arranged on both sides of the sampling housing 201. A second spring 204 is arranged between the clamping plates 203 and the sampling housing 201. When driving the clamping plates 203 to move, the clamping plates 203 squeeze the base 101, and the sampling housing 201 is fixed to the base 101. Filter boxes 202 are also arranged on both sides of the sampling housing 201. The filter boxes 202 communicate with the sampling housing 201. During sampling, the filter boxes 202 recover and process the leaked oil and gas in the oil tank. A winding roller 206 is rotatably arranged on the sampling housing 201. A lifting cable 207 is wound around the winding roller 206. A sedimentation plate 210 is arranged at the lower end of the lifting cable 207. An adsorption plate 211 is arranged on the sedimentation plate 210. A sampling box 205 is arranged on the sampling housing 201. The sampling box 205 is connected to the adsorption plate 211 through a hose. A pumping pump is arranged in the sampling box 205. When driving the pumping pump, the pumping pump samples the oil liquid in the oil tank through the hose and the adsorption plate 211. When driving the winding roller 206 to rotate, the winding roller 206 drives the lifting cable 207 to move, and the lifting cable 207 drives the sedimentation plate 210 and the adsorption plate 211 to enter the oil tank. A support plate 208 is arranged inside the sampling housing 201. The hose and the lifting cable 207 pass through the support plate 208. A scraping head 209 is also arranged inside the sampling housing 201. The scraping head 209 scrapes the surface of the lifting cable 207 to prevent the oil liquid contaminated on the lifting cable 207 from leaking.

[0026] Working principle: When it is necessary to close the base 101, rotate the pressing rod 106, and the pressing rod 106 drives the closing plate 109 to cover the base 101. Rotate the locking column 102, and the locking column 102 is inserted into the pressing groove 108. Rotate the rotating block 105 so that the rotating block 105 moves towards the pressing rod 106. The rotating block 105 presses the pressing rod 106. At this time, the pressing rod 106 presses the top plate 111, and the top plate 111 presses the closing plate 109 to fix the closing plate 109 on the base 101. When the rotating block 105 moves, the second pressing column 104 presses the pressing plate 110 through the third spring, and the pressing plate 110 presses the rotating block 105 to prevent the rotating block 105 from loosening during the transportation of the oil tank.

[0027] When it is necessary to sample the oil fluid in the base 101, rotate the rotary block 105 to rise. The rotary block 105 drives the pressing disc 110 and the second pressing column 104 to move. The second pressing column 104 retracts into the first pressing column 103. Rotate the locking column 102, and the locking column 102 disengages from the pressing groove 108. Rotate the pressing rod 106, and the pressing rod 106 drives the closing disc 109 to be removed from the base 101. Place the sampling shell 201 on the base 101, drive the clamping plate 203 to slide on the sampling shell 201. When the two groups of clamping plates 203 approach each other, they clamp the sampling shell 201 and fix the sampling shell 201 on the base 101. Start the filtering box 202, and the filtering box 202 absorbs the leaked oil and gas in the oil tank. Subsequently, drive the winding roller 206 to rotate. The winding roller 206 drives the lifting cable 207 to rotate, and the lifting cable 207 drives the sedimentation disc 210 into the oil tank. After immersing the adsorption disc 211 in the oil fluid, drive the extraction pump in the sampling box 205 to work. The oil fluid enters the sampling box 205 through the adsorption disc 211 and the hose, completing the sampling of the oil fluid.

[0028] When the sampling of the oil fluid is completed, drive the winding roller 206 to rotate. The winding roller 206 winds the lifting cable 207 on the lifting cable 207. When the lifting cable 207 passes through the scraping head 209, the scraping head 209 scrapes the residual oil fluid on the lifting cable 207 to prevent the leakage of the residual oil fluid on the lifting cable 207.

[0029] The present utility model is not limited to the above specific embodiments. Those skilled in the art in the technical field can make various transformations without creative labor starting from the above concepts, and all fall within the protection scope of the present utility model.
