DETAILED DESCRIPTION

[0013] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0016] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] like Figures 1-6 As shown, a large ship powered by a water hammer pump comprises a water inlet 1, a motor 101, a rack 102, a circular valve 103, a filter 104, a water inlet pipe 105, a wiper 106, a large centrifugal pump 2, a water lifting pipe 3, a one-way valve 4, a first piston connecting rod mechanism 5, a water discharge cylinder 6, a tailwater pipe 7, a tailwater pushing pipe 8, a water cylinder 9, a second piston mechanism 10, and a mechanical energy generator 11. Figure 6, a one-way valve 4 is provided at the water lifting pipe 3, the wall of the drain cylinder 6, and the tailwater push pipe 8. The one-way valve 4 is used to prevent water from flowing back; the first piston-connecting rod mechanism 5 includes a small piston 501. The first piston-connecting rod mechanism 5 is used to output mechanical energy for power generation; the drain cylinder 6 includes a drain valve 601 and a connecting rod mechanism. Tailwater holes are provided around it and communicate with the water cylinder 9; the tailwater pipe 7 is distributed around the tailwater cylinder; the tailwater push pipe 8 can recycle and desalinate seawater; a switched reluctance generator set is also provided at the large centrifugal pump 2; the second piston mechanism 10 includes a large piston 1001, a crankshaft 1002 and an air spring 1003; the air spring 1003 is used to provide power for the return stroke of the large piston 1001; the wiper 106 can remove marine life and other debris.

[0018] The one-way valve 4 of the tailwater pipe 7 is installed vertically upward. When the large piston 1001 pushes the tailwater, the one-way valve 4 is instantly pushed open and discharged upward for seawater desalination. When the large piston 1001 returns, the one-way valve 4 is instantly closed under the gravity of the tailwater. This prevents the tailwater from returning to the water cylinder. Other one-way valves 4 are installed around the wall of the drain cylinder 6 and are connected to the water cylinder 9 by pipes. When the large piston 1001 is in motion, the one-way valve 4 is closed, pushing the tailwater out through the tailwater pipe 7 and undergoing seawater desalination. When the large piston 1001 returns, the one-way valve 4 on the wall of the drain cylinder 6 is sucked open, sucking the water in the drain cylinder 6 into the water cylinder 9. When the large piston 1001 is in motion, the one-way valve 4 on the wall of the drain cylinder 6 is instantly closed.

[0019] Preferably, the mechanical energy power generation device is a high-pressure boiler boiling water power generation device 12, which includes a vacuum insulation chamber 13. The vacuum insulation chamber 13 includes a high-pressure pump 1301, a metal tungsten wire resistor 1302, and a steam turbine generator set 1303; the melting point of the metal tungsten wire resistor can reach above 3000°C; the volume of the vacuum insulation chamber is 5 meters × 5 meters × 5 meters, and it uses insulating and high-temperature resistant materials, and is connected to positive and negative direct current; the high-pressure boiler boiling water power generation device has no greenhouse gas emissions and can achieve carbon neutrality.

[0020] Preferably, the steam turbine generator set 1303 is connected to a hemispherical container 14 , which includes a condenser 1401 and a semipermeable membrane 1402 .

[0021] Preferably, the mechanical energy power generation device 11 is a supercritical carbon dioxide power generation device 15, which includes a CO2 collection chamber 1501, an air chamber 1502, a water pool 1503 and a generator set 1504; the CO2 collection chamber is located above the air chamber; the supercritical carbon dioxide power generation device is a scaled-down version of the supercritical carbon dioxide power generation device.

[0022] When using: Initially, the water inlet is closed. Once a large vessel is launched, a motor activates the rack and circular valve, allowing seawater to rapidly enter the ram pump. This also activates the large centrifugal pump and switched reluctance motor, acting as both a motor and a generator, regulating the speed and flow of water. This constant force converts linear motion through the crankshaft into circular motion, a repetitive cycle that generates mechanical energy and generates electricity. When the vessel is first launched, its power comes from the shore grid. Once the ram pump generates electricity, the shore grid is disconnected, eliminating the need for any onshore energy.

[0023] During operation, the piston-connecting rod mechanism does not contact the pump body, preventing any contact. The water inlet pipe and pump body are made of thick, pressure-resistant, vibration-free materials, resulting in silent operation. The water hammer pump operates by creating a water hammer effect when rapidly flowing water is suddenly obstructed. The water hammer force can reach over 10 MPa. This force is used to propel the piston back and forth, generating mechanical energy that drives the generator set. Since aircraft carriers, large and medium-sized ships, and other vessels at sea are mobile and in urgent need of mobile energy, the use of water hammer pumps for power generation offers a short construction period, low cost, and low maintenance, contributing to the development of a modern marine industrial system and the marine economy.

[0024] There are three parts that can generate electricity. Among them, the switched reluctance speed control motor of the centrifugal pump is both a generator and an electric motor, which is used to adjust the speed and flow of water. The size of the water inlet pipe and the pump body can be enlarged to a diameter of about 2 meters, and it needs to be made of strong materials that can withstand a pressure of more than 20 MPa; the centrifugal pump originally pumped water from downstream to upstream, but this application uses it in reverse, sending water from upstream to downstream. The best installation position is 15 meters of the 30-meter length of the water inlet pipe, which has both a drop and avoids the impact of the return force of the water hammer effect; the large piston is used to provide electricity while recycling tail water and pumping water for seawater desalination, which can obtain fresh water at low cost. Among them, the switched reluctance speed control motor is equipped with a large exciter, which has many advantages such as large torque, no cutting of magnetic lines of force, and high power generation efficiency. Example

[0025] The high-pressure boiler-boiled water power generation device 13 generates electricity. Water is pumped in by a high-pressure pump 1301, then heated by a metal tungsten wire resistor 1302, boiling the water and evaporating it into steam. This steam drives the steam turbine generator set 1303 to generate electricity. Waste heat from the steam turbine enters the condenser, where it is recovered and fed back into the high-pressure boiler. During this process, the second piston mechanism 10 is a large piston 1001, with a stroke retaining the dimensions of a diesel engine. The water inlet pipe and pump body are enlarged to approximately 2 meters and can be replaced according to actual needs. This process achieves high energy density, and after energy boosting, the boiled water reaches a supercritical state. The steam turbine generator set can generate millions of kilowatts of clean energy, providing power for large-scale mobile power plants and ships. The semipermeable membrane 1402 also recycles and filters pumped water and tailwater, achieving the technical effect of producing desalinated seawater. This can also be used in water conservancy projects within the external water tower distribution network to address inland water shortages.

[0026] Based on existing technology, this application eliminates the need for hyperbolic cooling towers, saving significant construction costs and freshwater resources, reducing commercial operating costs and floor space. Assembling the system on ships makes it suitable for confined spaces, using only gravity to generate electricity around the clock, outputting clean energy and achieving carbon neutrality. Integrating the entire water hammer system and semipermeable membrane desalination device on a ship creates a mobile power plant while also providing access to desalinated river water, addressing freshwater resource issues on land and in industrial cities. Example

[0027] A scaled-down supercritical carbon dioxide power generation device 15 generates electricity. A piston compresses the gas and passes it through a heating zone to push another cylinder or multiple pistons to generate power. The discharged carbon dioxide gas is desalinated via pumped water and tailwater. The cooled carbon dioxide is then recovered and returned to the compressed carbon dioxide cylinder to achieve infinite cycle power generation without the need for carbon dioxide replenishment. A water hammer pump provides power to drive the second piston mechanism 10 to compress the CO2 and flush it into the CO2 collection chamber 1501. The temperature in the air chamber reaches over 1000°C. The compressed CO2 achieves a pressure of 20 MPa and is then heated to over 1000°C to obtain supercritical CO2. Because the present invention is a scaled-down supercritical carbon dioxide power generation device, its critical point is very low and high efficiency is easily achieved. It is not restricted by weather or region, and does not require energy storage, allowing for all-weather operation. The water hammer effect combines with the piston motion principle to output mechanical energy through cyclical repetitive motion, achieving the technical effect of all-day power generation and also recovering pumped water and tailwater.

[0028] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
