DETAILED DESCRIPTION

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-5 As shown, an integrated oil unloading device for railway oil unloading includes an extraction pipe 1, a main sealing ring 2 installed on the outside of the extraction pipe 1, and a sealing gasket 3 fitted on the inner wall of the main sealing ring 2. Furthermore, sealing blocks 4 are provided on both sides of the sealing gasket 3. With this arrangement, when the main sealing ring 2 is screwed to the sealing gasket 3 and tightly attached to the oil tank, the sealing gasket 3 can be deformed by the setting of the sealing blocks 4, which further improves the sealing effect. During oil unloading, the extraction pipe 1 is inserted into the oil tank, and the main sealing ring 2 is screwed to tighten the main sealing ring 2 with the opening of the oil tank, thereby allowing a part of the extraction pipe 1 to be inserted into the oil tank, and the oil in the oil tank is extracted through the extraction pipe 1.

[0025] An adsorption sheet 5 is installed on one side of the main sealing ring 2. The adsorption sheet 5 can adsorb the liquid around the main sealing ring 2. The material of the adsorption sheet 5 can be non-woven fabric or other materials. Multiple humidity sensors 6 are installed on the adsorption sheet 5. A controller is also installed inside the main sealing ring 2. A solenoid valve 7 is installed inside the extraction tube 1. The solenoid valve 7 is installed in the section of the extraction tube 1 that is inserted into the oil tank. When it is necessary to shut down the oil extraction in an emergency, the solenoid valve 7 can be shut down, thereby canceling the oil extraction of the extraction tube 1. The controller is electrically connected to the humidity sensors 6 and the solenoid valve 7.

[0026] When oil leaks, it can be adsorbed by the adsorption sheet 5. Once the adsorption sheet 5 adsorbs the oil and is detected by the humidity sensor 6, the humidity sensor 6 will shut off the solenoid valve 7 through the controller, thereby urgently canceling the oil extraction.

[0027] See attached document Figure 3 A sliding groove 12 is provided on the outer side of the main sealing ring 2, and an auxiliary sealing ring 8 is slidably connected in the sliding groove 12. A driving mechanism is installed on the main sealing ring 2 to drive the auxiliary sealing ring 8 to move. Furthermore, a gasket 13 is provided on one side of the auxiliary sealing ring 8. The gasket 13 allows it to fit tightly against the oil tank and deform upon contact, thereby sealing the oil tank. (Refer to the attached document.) Figure 3 and attached Figure 4 The drive mechanism includes a mounting plate 9 fixed on the outside of the main sealing ring 2. A motor 10 is mounted on one side of the mounting plate 9. An abutment block 11 is fixed to the output end of the motor 10. When the abutment block 11 rotates, it drives the auxiliary sealing ring 8 to move.

[0028] When the oil body leakage is detected by the dry and wet sensor 6, the motor 10 can be simultaneously driven by the controller, so that the output end of the motor 10 drives the abutting block 11 to rotate, when the abutting block 11 rotates, the auxiliary sealing ring 8 is first abutted, after the contact, the abutting block 11 continues to rotate and drives the auxiliary sealing ring 8 to move, until the auxiliary sealing ring 8 contacts with the oil tank, so that the auxiliary sealing effect is achieved.

[0029] Refer to the drawings Figure 5 The extraction pipe 1 and the side of the electromagnetic valve 7 are provided with a mounting groove 14, the inside of the mounting groove 14 is slidably connected with a moving piece 15, the mounting groove 14 is further assembled with a spring 16, and the spring 16 is connected with the moving piece 15.

[0030] When the electromagnetic valve 7 is closed, a large amount of oil body continues to move along the extraction pipe 1, at this time, the impact force of the oil body moving to the surrounding of the electromagnetic valve 7 can be buffered by the spring 16 through the setting of the moving piece 15, so that the oil body impacts the moving piece 15, thereby achieving the pressure relief effect of the electromagnetic valve 7.

[0031] The above is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the technical field, without departing from the principle of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application. The structure, device and operation method not specifically described and explained in the present application, if no special description and limitation, are implemented according to the conventional means in the art.
