Detailed Description
In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:
as shown in fig. 1, the present embodiment provides a vertical fluctuation range slowing device, which mainly comprises a floating island module 1, a constant water level water tank 2, a rubber water bag 3, a communicating pipe 4, a PLC automatic control system, and the like.
The floating island is typically made up of a plurality of reinforced concrete or steel floating island modules 1. The floating island module 1 is divided into upper and lower cells by a diaphragm. The space between the upper and lower cells is sealed and watertight, the top of the upper cell is closed, the bottom of the lower cell is open, and the bottom of the lower cell is provided with a grid plate 5.
The constant water level water tank 2 is arranged in the upper grid chamber, and the constant water level water tank 2 is provided with an overflow hole and is connected with the drainage pipe 6 through the overflow hole. The liquid level in the constant water level water tank 2 is constant, and when the water stored in the constant water level water tank exceeds the constant liquid level, the water is discharged from the overflow hole through the water discharge pipe 6.
The liquid level meter 7 is further arranged inside the constant water level water tank 2, and the liquid level meter 7 can be fixedly installed on the side wall of the constant water level water tank 2 and used for measuring the water level in the constant water level water tank 2 in real time. The liquid level meter 7 is in signal connection with the first PLC controller 8, and the first PLC controller 8 is in signal connection with the water pump 9.
The rubber water bag 3 is arranged in the lower grid chamber, and water is filled in the rubber water bag 3. The rubber water bag 3 is communicated with the constant water level water tank 2 through a communicating pipe 4, and the communicating pipe 4 can enable water in the rubber water bag 3 and water in the constant water level water tank 2 to mutually circulate. The rubber water sac 3 is a sac structure made of high-elasticity rubber, can be internally filled with water and has high elasticity.
The top of the rubber water bag 3 is also provided with an air pressure tester 10, and the air pressure tester 10 can be fixedly installed at the bottom of the diaphragm plate of the floating island module 1 and is used for monitoring the air pressure at the top of the rubber water bag 3 in real time. The air pressure tester 10 is in signal connection with a second PLC (programmable logic controller) 11, and the second PLC 11 is in signal connection with a vacuum pump 12.
Under the operating condition of vertical fluctuation range retarding device:
rubber water pocket 3 is full of water and lay in lower part check indoor, works as great wave action force and is used for 3 bottoms of rubber water pocket, and rubber water pocket 3 receives hydrodynamic force and strikes and compress, and the water pressurized in the rubber water pocket 3 is extruded by communicating pipe 4, gets into in the constant water level water pitcher 2. When the water in the constant water level water tank 2 is increased to a constant water level, the water flows out of the overflow hole and is drained by the drain pipe 6. When smaller wave action force acts on the bottom of the rubber water bag 3, the water power is reduced or disappears, the rubber water bag 3 is compressed and deformed to recover, and water in the constant water level water tank 2 flows into and supplies the space in the rubber bag from the communicating pipe.
The water level in the constant water level water tank 2 is measured by the liquid level meter 7 in real time, the first PLC 8 receives the current water level signal transmitted by the liquid level meter 7 in real time, and converts the current water level signal into a current water level value which is compared with a designed water level value p 0.

When the second PLC controller 11 determines that the current air pressure value is greater than 0, which indicates that air exists in the rubber water bag 3, the second PLC controller 11 transmits a signal to the vacuum pump 12 to start the vacuum pump 12. The vacuum pump 12 pumps air existing in the rubber water bag 3 until the second PLC 11 judges that the current value is 0, which indicates that the air pumping is finished, and the second PLC 11 sends a signal to the vacuum pump 12 to close the vacuum pump 12.
