[0033] See also Figure 8 A fixing clamp ring 11 is provided on the outer edge of the tank mouth 1, and a fixing buckle ring 224 is provided at the lower end of the sliding buckle seat 22. The lower end of the fixing clamp ring 11 is an inclined surface inclined upward from the outside to the inside, and the upper end of the fixing buckle ring 224 is an inclined surface inclined upward from the outside to the inside. The lower end of the fixing clamp ring 11 and the upper end of the fixing buckle ring 224 are matched with each other. When the sliding buckle seat 22 moves toward the center of the cover plate 21, the fixing buckle ring 224 is buckled with the bottom of the fixing clamp ring 11.

[0034] The working principle and use process of this utility model:

[0035] When the tank mouth 1 is not connected to the movable component 2, the opening and closing conical ring 52 and the sliding buckle seat 22 are abutted by the auxiliary roller 221, and several fixed protrusions are abutted and buckled with the bottom of the clamping buckle, and the lifting motor 31 drives the lifting seat 34 to descend. After the cover plate 21 abuts against the tank mouth 1, the clamping cylinder 42 retracts, and the lifting clamp block 44 is driven away from the clamping buckle, and the lifting clamp block 44 is disconnected from the clamping buckle, and the opening and closing cylinder 51 retracts, driving the opening and closing conical ring 52 to rise. Due to the action of the tension spring 223, the sliding buckle seat 22 will move toward the center of the cover plate 21, and the fixed buckle 224 is buckled with the bottom of the fixed clamp ring 11. At this time, the cover plate 21 completely covers the tank mouth 1 and the sliding buckle seat 22 can fix the position of the cover plate 21 on the tank mouth 1, so that the tank mouth 1 is closed, and the lifting motor 31 drives the lifting seat 34 to retract.

[0036] When it is necessary to open the tank mouth 1, the lifting motor 31 drives the lifting seat 34 to descend and reach above the cover plate 21, the opening and closing cylinder 51 extends, and the opening and closing conical ring 52 abuts against the sliding buckle seat 22 through the auxiliary roller 221, and moves the sliding buckle seat 22 in the direction away from the center of the cover plate 21, and the fixed buckle ring 224 and the fixed clamp ring 11 are disconnected, the clamping cylinder 42 extends, and the lifting clamp block 44 is driven close to the clamping buckle ring, and the lifting clamp block 44 abuts against the bottom of the clamping buckle ring to realize the connection between the clamping assembly 4 and the cover plate 21, and the lifting motor 31 drives the lifting seat 34 to retract, and the cover plate 21 leaves the tank mouth 1, and finally the tank mouth 1 is opened.

[0037] This structure is self-locking. Even if the power is lost, the buckling between the lifting clamp block 44 and the clamping buckle will become tighter and tighter due to the gravity of the cover, which is safer. Since the tank mouth 1 will expand or contract due to the air pressure in the tank body, the fixed clamp ring 11 will be subjected to positive pressure or negative pressure from the tank mouth 1. When subjected to positive pressure, the fixed clamp ring 11 and the fixed buckle 224 are buckled tighter and tighter. When subjected to negative pressure, due to the gravity of the tank body, the fixed buckle 224 can still ensure that the fixed clamp ring 11 is buckled.

[0038] In order to further limit the descending stroke of the opening and closing assembly 5 and the clamping assembly 4, in this embodiment, the lifting seat 34 is provided with a limit column 36 and a limit sensor. The limit column 36 slides within the limit position on the lifting seat 34. The upper end of the limit column 36 is connected to the connecting seat 32 through a reset spring, and the lower end is fixedly connected to the limit sensor.

[0039] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
