detailed description

As shown in Figure 1, Figure 2 and Figure 3, a marine tidal energy telescopic cylinder water pump of the present invention includes a lower base cylinder 3, an upper buoy water inlet and drainage control valve 5, an upper buoy 6, a telescopic cylinder water inlet control valve 7, an upper buoy Vent pipe 8, upper support cylinder 10, telescopic cylinder and telescopic cylinder drainage control valve 9, telescopic cylinder is composed of two flanges 11 and telescopic cylinder body 12, telescopic cylinder body 12 is located between the two flanges 11, telescopic The two flanges 11 of the cylinder are respectively connected with the upper supporting cylinder 10 and the lower base cylinder 3 by bolts and nuts. The volume of the telescopic cylinder increases when it is stretched, and its volume decreases when it is compressed. The lower base cylinder 3 is located below the telescopic cylinder assembly 11 , the lower base cylinder 3 has a drain port 1 , and the drain port 1 has a telescopic cylinder drainage control valve 9 . There is a floating body assembly above the telescopic cylinder, and the floating body assembly includes an upper support cylinder 10, a plurality of hollow upper buoys 6 and a telescopic cylinder water inlet control valve 7, and a plurality of hollow upper buoys 6 are connected with the upper support cylinder 10, The top of the upper buoy 6 has an upper buoy vent pipe 8, and the bottom of the upper buoy 6 has an upper buoy water inlet and drain control valve 5, so as to discharge water at a high tide level and a low level, so as to ensure that the cavity of the upper buoy is filled with water during the ebb tide of the ocean. The seawater under the gravity of the buoy makes the buoy drive the telescopic cylinder to float up to a high position during the high tide of the ocean. The bottom of the lower base cylinder 3 is fixedly connected with a base plate 2, and the base plate 2 is fixed with a support column 4. The support column 4 passes through the edge of the lower base cylinder 3 and the edge of the upper support cylinder 10. With the progress of the ocean tide, the buoyancy of the upper buoy, Under the action of gravity, the floating body assembly can move up and down in the vertical direction along the support column 4 .

This kind of marine tidal energy telescopic cylinder water pump moves the ocean tidal energy telescopic cylinder water pump to the ocean when in use, and can connect the bottom plate with the seabed, and utilize the drop of ocean tides to increase the intake and drainage buoys by controlling the upper buoy to enter seawater at high tide. The overall weight realizes that during the ebb process, the compression of the telescopic cylinder causes the seawater in the lower base cylinder to generate high pressure (the water inlet control valve of the telescopic cylinder is closed during this process), forcing the water in the lower base cylinder to be discharged through the drain on the cylinder; During the high tide process (the water inlet control valve of the telescopic cylinder is opened during this process), the seawater is discharged through the upper buoy at low tide, and the buoy increases the buoyancy, driving the telescopic cylinder to stretch and float up to the high tide level, and then enter the ebb process. Along with the continuous progress of ocean tides, the above-mentioned processes are repeated continuously to realize the pumping of seawater into high-altitude reservoirs, water storage for power generation, seawater desalination, seawater farming, seawater drying and other applications.
