[0031] like Figures 1-6 As shown, a mechanical valve opening and closing device includes a floating device and a tubular structure 6. The floating device includes a float 12, a guide rod 7, an upper push rod 8, a lower pull rod 9, and a limiting guide 11. One end of the tubular structure 6 is connected to an annular structure 10, which is located between the upper push rod 8 and the lower pull rod 9. The other end of the tubular structure 6 is linked to a valve 3 on the outlet pipe 2 via a gear assembly. The tubular structure 6 only needs to rotate less than 30° to fully open and close the ball valve 3. The middle part of the tubular structure 6 is fixed on a bearing 17 and rotates around the bearing 17. The device is externally connected to an inlet 1. When the device is in use, the valve 3 on the outlet pipe 2 is opened and closed instantaneously by the vertical displacement of the floating device. During use, the valve 3 will not open and close repeatedly when closed.

[0032] The guide rod 7 is located on the float 12 and is arranged longitudinally. An upper push rod 8, a lower pull rod 9, and a limiting guide 11 are mounted on the guide rod 7. The upper push rod 8 is located below the lower pull rod 9, and limiting guides 11 are provided on the upper and lower sides of both the upper push rod 8 and the lower pull rod 9. The up-and-down movement of the float 12 causes the upper push rod 8 and the lower pull rod 9 on the guide rod 7 to push and pull the annular structure 10 up and down, thereby controlling the movement of the tubular structure 6. The device operates through the coordinated operation of its components, making it more convenient to use.

[0033] The tubular structure 6 is provided with a metal ball, one side of the outer wall of the tubular structure 6 is provided with a push rod 14, the push rod 14 is connected with a gear assembly, and the control gear assembly is linked with the tubular structure 6. The gear assembly comprises a gear a4 and a gear b5, the gear a4 is linked with the gear b5, the diameter of the gear a4 is larger than that of the gear b5, the gear a4 is installed on a shaft 13, the gear a4 is provided with a push rod 15, the push rod 15 is arranged in close contact with the push rod 14 and below the push rod 14. The gear a4 is connected with the valve 3 on the water outlet pipe 2, the bottom end of the water outlet pipe 2 extends to the bottom of the device and is arranged close to the bottom of the device. The shaft 13 is fixedly installed on a bearing 17 at the bottom of the tubular structure 6. The tubular structure 6 of the device is driven by the floating device to rotate around the bearing 17, and the gear assembly is driven by the push rod 14 to link, the device structure is stable, and the practicability is good.

[0034] When the device is used, liquid enters the device from the water inlet 1, and after reaching a certain liquid level, the upper push rod 8 of the floating device pushes the annular structure 10 to move upwards, drives the tubular structure 6 to rotate, and when the tubular structure 6 exceeds the horizontal line, the metal ball in the tubular structure 6 rolls to the left, the push rod 14 of the tubular structure 6 drives the push rod 15, the push rod 15 and the gear a4 rotate around the gear center, drive the gear b5 connected with the valve 3, so that the valve 3 is opened, the liquid in the device is discharged through the water outlet pipe 2, and the floating device moves downward with the liquid level. When the liquid level is lowered to a certain position, the lower pull rod 9 pulls the annular structure 10 to move downwards, drives the tubular structure 6 to rotate, and when the metal ball rolls to the right after passing the horizontal line, the tubular structure 6 continues to rotate to the right, the push rod 14 of the tubular structure 6 drives the gear a4 to rotate, and the gear a4 drives the gear b5 to close the valve. The device is operated in the above cycle.
