Furthermore, a plurality of second bolts are uniformly arranged on the upper cover plate and the lower cover plate of the component in the circumferential direction and do not contact with the periphery of the plastic pipe of the component. Strengthen the fixed action of apron about the subassembly on the one hand, on the other hand for the kickboard subassembly when reciprocating, a track is decided to the frame, prevents that the kickboard subassembly from overturning when reciprocating.
Furthermore, a circle of boss is arranged on the inner surface of the lower cover plate along the water outlet, and a sealing ring is arranged on the outer edge of the boss. The boss is used as a device for installing the sealing ring to strengthen sealing.
Further, the specific gravity of the floating plate assembly is controlled to be 1.05-1.2. The specific gravity of the water is 1, so that the floating plate assembly can automatically sink in the water.
When the device is used, the water outlet of the device is connected with the water inlet of the steel cylinder. At the moment, the water inlet sealing device can sink in water along with the steel cylinder. When the air pressure in the steel cylinder is communicated with the atmospheric pressure (namely when the steel cylinder needs to be filled with water), water enters from the water inlet of the device, and when the water enters, the upward pressure of the water pushes away the floating plate assembly, and the water flows into the water inlet of the steel cylinder through the water outlet of the device so as to flow into the steel cylinder (because the steel cylinder sinks into the water and a pipe (a gas release switch) for communicating the atmosphere is arranged in the cylinder, the normal atmospheric pressure is achieved in the steel cylinder, as shown in figure 2). When the air pressure in the steel cylinder is not changed, water can continuously flow into the steel cylinder from the water outlet after flowing in from the water inlet of the device. Therefore when the surface of water is not level with the outer surface of water of steel cylinder in the steel cylinder (the pressure that the surface of water outside the steel cylinder produced is greater than the inside atmospheric pressure of steel cylinder), water can be ceaselessly from the water inlet inflow, and water pressure can withstand the kickboard subassembly always and not let the kickboard subassembly sink to the water inlet that leads to the device is open state always. When the water level in the steel cylinder is flush with the outer water level of the steel cylinder (because the steel cylinder is immersed in water to work at ordinary times, the steel cylinder is filled with water at the moment, namely the water level in the steel cylinder is actually arranged in a plurality of pipelines at the top of the steel cylinder), the external water stops flowing into the device from the water inlet at the moment. At the moment, because the specific gravity of the floating plate component is greater than that of water, the floating plate component automatically sinks in the water to block the water inlet of the device. Then when compressed air is input into the steel cylinder through the pipe with air (the process requires that the air inlet switch is opened and the air outlet switch is closed), the floating plate assembly is blocked at the water inlet of the device, the water pressure in the cylinder is raised at the moment, the water pressure is increased on the floating plate assembly, and the sealing ring arranged on the water inlet can be completely sealed under the pressure. This is an ideal sealing device, which can repeat the water inlet process when there is no water in the cylinder.

Detailed Description
A sealing device for rapid water inlet is shown in figure 1 and comprises a cylinder body (02), an upper cover plate (01), a lower cover plate (04) and a floating plate assembly (03) arranged in the cylinder body (02); the top of the cylinder body (02) is sealed by an upper cover plate (01), the bottom of the cylinder body is provided with a lower cover plate (04) with a water inlet, and the side wall of the cylinder body (02) comprises a water outlet. Referring to fig. 2, the floating plate assembly (03) comprises an upper cover plate (03-01) and a lower cover plate (03-01) of the assembly and a plastic pipe (03-02) of the assembly, wherein the upper cover plate (03-01) and the lower cover plate of the assembly seal the upper end and the lower end of the plastic pipe (03-02) of the assembly. As shown in fig. 3, a plurality of first bolts (a circle of bolts on the outer ring in fig. 3) are uniformly arranged on the upper cover plate (01) and the lower cover plate (04) in the circumferential direction and do not contact with the periphery of the floating plate assembly (03). A plurality of second bolts (a circle of bolts of an inner ring in figure 3) are uniformly arranged on the upper cover plate (03-01) and the lower cover plate of the component in the circumferential direction and are not in contact with the periphery of the plastic pipe (03-02) of the component. As shown in FIG. 4, a circle of bosses are arranged on the inner surface of the lower cover plate (04) along the water outlet, and sealing rings are arranged on the outer edges of the bosses. The specific gravity of the floating plate assembly (03) is 1.1.
The using method comprises the following steps: as shown in figure 5, the water outlet of the device is connected with the water inlet of the steel cylinder. At the moment, the water inlet sealing device can sink in water along with the steel cylinder. When inside atmospheric pressure of steel cylinder and atmospheric pressure UNICOM (when the steel cylinder needs to intake promptly, there is pipeline and atmospheric pressure UNICOM in the steel cylinder this moment), water gets into from the water inlet of the device, and during the entering, the ascending pressure of water pushes away the kickboard subassembly 03, and thereby water passes through the delivery port of the device, flows in the water inlet of steel cylinder and flows in the steel cylinder (gassing switch 05 is opened, air inlet switch 06 closes, is normal atmospheric pressure in the steel cylinder). When the air pressure in the steel cylinder is unchanged, water can continuously flow into the steel cylinder from the water inlet of the steel cylinder after flowing into the water inlet of the device. Therefore, when the water surface in the steel cylinder is not level with the outer water surface of the steel cylinder (the pressure generated by the water surface outside the steel cylinder is greater than the atmospheric pressure inside the steel cylinder), water can continuously flow into the water inlet of the device, and the water pressure can continuously support the floating plate assembly 03 so as not to enable the floating plate assembly 03 to sink, so that the water inlet of the device is always in an open state. When the water level in the steel cylinder is level with the water level outside the steel cylinder (because the steel cylinder is sunk into the water for working at ordinary times, the water level in the steel cylinder is actually the water level in a plurality of pipelines at the top of the steel cylinder), the external water stops flowing into the device from the water inlet at the moment. After outside water does not flow into the device from the water inlet, the pressure generated during water flowing is lost, and at the moment, because the specific gravity of the floating plate component 03 is greater than that of water, the floating plate component 03 automatically sinks in the water to block the water inlet of the device. When compressed air is input into a pipe communicated with the atmosphere on the steel cylinder (at the moment, the air inlet switch 06 is opened, the air outlet switch 05 is closed, the water outlet 07 is filled with water and is equivalently closed), the floating plate component 03 is blocked at the water inlet of the device, at the moment, the pressure of the water surface in the cylinder is increased by the compressed air in the air inlet switch 06, and the pressure is applied to the floating plate component 03 through water conduction. The sealing ring arranged on the water inlet can be completely sealed under pressure. Therefore, water in the steel cylinder is pressed out of the steel cylinder from the water outlet 07 by high-pressure gas, and when no water exists in the steel cylinder, the device can repeat the water inlet process.
