Description

Technical Field

[0001] The invention relates to the technical field of water hammer power, and in particular to a power system of water hammer effect. Background Art

[0002] The earth is rich in water resources, with nearly 70% of its surface area covered by water, but hydropower accounts for less than 17% of the world's total electricity generation. Due to the high water level and large flow of traditional hydropower, building dams has become a necessary procedure, but how much space do we have for building dams? Building dams requires a lot of manpower, financial resources, and material resources, as well as a long construction period, which has an irreversible and great impact on the environment. Traditional hydropower is extremely expensive and difficult to build, so it generally requires national or large consortiums to be involved. The above factors are deadlocks, which seriously hinder the further development of hydropower.

[0003] The "power system of water hammer effect" invented by me has opened up a broad prospect for further development of natural water energy. It is a solution that was inspired by the water hammer phenomenon caused by a broken faucet.

[0004] More than 10 years ago, the faucet in the kitchen of the inventor's home was broken. After turning off the water source, a small amount of water dripped and the faucet vibrated strongly. The vibration spread throughout the entire building along the pipes hanging on the outer wall, especially at night and early in the morning. After repeated observation, it was found that the faucet vibrated and leaked only after the water source was suddenly turned off. If the water source was turned off slowly, this phenomenon would not occur. This was obviously a "water hammer phenomenon" and the 38-gram faucet accessories were being hit by the water hammer.

[0005] Water hammer phenomenon: When the water flow in the pipe is suddenly blocked, but the water behind continues to squeeze forward, it will produce an impact force of dozens to hundreds of times the normal water pressure. The water hammer phenomenon caused by a broken faucet is another way for nature to show us how to obtain natural water energy.

[0006] The inventor has repeatedly observed and tested the phenomenon of bad faucets and found that it is very stable. In three of the tests, the amount of water discharged after 100 vibrations was 150 grams, 150 grams, and 130 grams respectively, with an average of 1.5 grams of water per vibration. This 1.5 grams of water discharge can make the entire building restless, which is the powerful power generated by water hammer energy.

[0007] Based on this, if we use one kilogram of displacement, we can get more than 600 times the vibration effect. What if we expand it to 10,000 times? However, this 10,000 times displacement is only 15 kilograms. What can this 15 kilograms of water do if it is used in a hydraulic turbine? From this point, we can see the great potential of developing water hammer power.

[0008] Many people are also full of longing for the energy generated by the water hammer phenomenon. There are some records in the patent literature data, but so far no one has been able to show that the water hammer effect can have the basic conditions to be used as power. If the water hammer energy obtained is low, it will not be worth further developing into power.

[0009] In order to turn the energy generated by water hammer into power, we must solve the problem of continuous and effective impact. There are two problems: one is "continuous"; the other is "effective impact". Continuity is the foundation. Without continuity, there is no condition for power. Effective impact is the root of the value of power. Only when it can be effectively impacted can it have great value as power. The water hammer effect can generate energy up to 200 times the original water pressure. If we can currently make the water hammer effect generate 300 to 40 times the energy and the acquisition rate can reach 70 to 80%, it will have great value to be developed into power. This is the connotation of effective impact. Regardless of the energy generated by the water hammer effect or the acquisition rate, it will continue to improve with the advancement of technology.

[0010] The water hammer phenomenon caused by a broken faucet can cause a stir in the entire building with only 1.5 grams of water discharged per vibration. How can such a high-efficiency vibration effect be achieved with 1.5 grams of water discharged each time to hit the 38-gram faucet accessories? After continuous observation and thinking, the inventor realized the "leakage drainage technology" solution, which solved the problem of continuous and effective impact. It has found an efficient, simple and cheap method to further develop natural water. In the future, hydropower generation will become an engineering project that general companies can undertake.

[0011] There are many places in nature with huge drop in water level but no conditions for building dams, or high water level but not that large flow, which are all good places for water hammer power devices to show their functions. There is no need to build dams, and laying pipelines is the main infrastructure, which can save a lot of manpower, financial resources, material resources and construction period, and has little impact on the environment. The currently popular pumped storage power generation can increase the efficiency many times if water hammer power devices are used. Based on pumped storage, power generation can be achieved by just digging a pit where there is water.

[0012] In the prior art, the water hammer effect is produced with low efficiency and long intervals, and cannot form a continuous and stable power output. Summary of the invention

[0013] In view of the deficiencies in the prior art, the present invention provides a power system for the water hammer effect. After the loosening ring and the water drainage collection ring on the inner wall of the cylinder body drain the pressurized water inside the system, the piston is quickly restored to a position without impact and compression, and then enters the next stamping stroke of the piston. Compared with the prior art, the time for impact, compression and return of the piston is shortened, the efficiency of water hammer impact is increased, and continuous and stable power output is generated.

[0014] In order to achieve the above object, the present invention adopts the following technical solution:

[0015] A power system for water hammer effect, comprising a pressure cylinder connected to a pressure water pipe, a pressure branch pipe being arranged on the pressure water pipe, a detonation valve being installed on the pressure branch pipe, a hollow chamber being arranged on the pressure cylinder, a piston being slidably installed inside the hollow chamber, a piston rod being installed on the end of the piston away from the pressure water pipe, the piston rod penetrating to the outside of the pressure cylinder and being slidably connected to the pressure cylinder, a water drainage chamber being arranged in the hollow chamber, the water drainage chamber comprising a loosening ring and a water drainage collecting ring, a water drainage port being opened on the water drainage collecting ring; a dense ring being arranged adjacent to the loosening ring, the dense ring being located on the inner wall of the cylinder body and close to the pressure water pipe, and the piston slidingly sealingly when in contact with the dense ring.

[0016] As a preferred technical solution of the present invention, the pressure cylinder comprises a cylinder head and a cylinder body, and the cylinder head and the cylinder body are connected by cylinder bolts;

[0017] As a preferred technical solution of the present invention, the hollow chamber includes a stroke chamber, a drain chamber and a stroke chamber connected in sequence, the drain chamber includes a loose ring surrounding the piston; the diameter of the stroke chamber is smaller than the diameter of the piston, the diameter of the loose ring is larger than the diameter of the piston, and the piston reciprocates inside the stroke chamber;

[0018] As a preferred technical solution of the present invention, the loosening ring includes a loosening ring and a drain collecting ring which are interconnected, one end of the loosening ring adjacent to the stroke chamber maintains a relative distance from the end of the piston, and the diameter of the drain collecting ring is greater than the diameter of the loosening ring;

[0019] As a preferred technical solution of the present invention, a drain port is provided at the bottom of the drain collection circle;

[0020] As a preferred technical solution of the present invention, a plurality of blind holes are provided at the end of the stroke chamber away from the piston, and springs are installed inside the blind holes, and the springs abut against the piston;

[0021] As a preferred technical solution of the present invention, the free end of the piston rod is connected to a crankshaft through a connecting rod, and the crankshaft is connected to a generator;

[0022] As a preferred technical solution of the present invention, the pressure water pipe and the cylinder head are sealed and fixedly connected via a flange;

[0023] As a preferred technical solution of the present invention, the input end of the pressure water pipe is connected to a high-pressure water interface;

[0024] As a preferred technical solution of the present invention, the detonation valve is a fast-closing butterfly valve, a gate valve, or an electromagnetic shut-off valve.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, a pressure water source is connected to the input end of the pressure water pipe, and the front part of the pressure water pipe and the hollow chamber are filled with pressurized water; when the detonation valve is opened to discharge the pressure water, and then the detonation valve is suddenly closed, an instantaneous pressure wave is generated due to the inertia of the water flow, and this pressure wave will impact the piston and the pipe wall like a hammer, thereby generating a water hammer effect; the generated water hammer effect impacts the piston, causing the piston to move rapidly in a direction away from the pressure water pipe, and when the piston moves to the position of the loosening circle, the pressure water inside the pressure water pipe and the hollow chamber is rapidly discharged from the loosening circle, at this time, negative pressure is generated at the front end of the pressure water pipe and the hollow chamber, and with the assistance of the spring, the piston and the piston rod move together in the direction of the pressure water pipe; when the pressure inside the pressure water pipe and the hollow chamber is greater than the bearing capacity of the piston, the piston moves in a direction away from the pressure water pipe, and the above actions are repeated over and over again, thereby generating reciprocating motion, and the piston rod generates a stable linear reciprocating motion along with the piston, which is conducive to generating a stable kinetic energy output. The present invention can obtain the energy generated by the water hammer to the maximum extent through the function of the special structure of the loosening circle, so that the water hammer effect has the conditions to become a continuous and stable power.

[0027] In the present invention, the detonation valve is suddenly closed after being opened, and the water hammer phenomenon is caused due to the sudden interruption of the water flow. The water hammer hits the piston, and the piston moves from the first position (the end of the piston is close to the cylinder head) to the second position (the end of the piston is far away from the cylinder head). According to the principle of mechanics, the greater the impact force, the greater the reaction force, the equal but opposite reaction force will be. This reaction force acts on the water body, and while instantly preventing the subsequent water pressure from advancing forward, it drives the piston to move back to the first position. At the same time, after completing a round of impact, the water hammer puts the device in a short state of no force. In this way, even if the piston is on the loose circle of the second position, the contact between the piston and the pressure cylinder is relatively close, and the sticking effect of the residual water between the piston and the cylinder body is sufficient to prevent the outside air from entering the cylinder body. According to the principle of vacuum science, the piston at this time will be tightly adsorbed on this water body and move back to the first position with this water body. In addition, after the water in the container is hit by an external force against the container wall on one side, it will drift in the opposite direction. This is the "reverberation" of water, and the reverberation of water helps to return the piston to the first position. Therefore, the piston moves back from the second position to the first position due to the combined effect of multiple factors, which enables the piston to successfully complete the return stroke. The piston moves back to the first position, and the subsequent pressure water hits the piston again, causing the water hammer impact again, and this reciprocating process continues, and the device produces continuous and stable power output.

[0028] 2. The loosening ring of the drain chamber in the present invention is close to one end of the stroke chamber and maintains a relative distance from the end of the piston. The diameter of the drain collection ring is larger than the diameter of the loosening ring, and a drain port is provided at the bottom of the drain collection ring. The loosening ring is arranged close to the outer wall of the piston, and the loosening ring is arranged along the axial direction of the piston; the drain collection ring is connected to the loosening ring, and the diameter of the drain collection ring is larger than the loosening ring, and the drain collection ring can quickly collect water leaked from the loosening ring;

[0029] In the present invention, the loosening ring is set to be narrow and long, which is conducive to the stable and long-term water discharge at the loosening ring during the compression of the piston, and increases the stroke of the piston on the loosening ring; during the water discharge of the loosening ring, the water film is always attached between the piston and the cylinder body, preventing the external air from entering the inside of the pressure water pipe, which is conducive to the reciprocating motion of the piston, and further promotes the device of the present invention to produce stable and continuous power output. After the loosening ring and the water discharge collection ring on the inner wall of the cylinder body discharge the pressure water inside the system, the piston is quickly restored to the position without impact and compression, and then enters the next stamping stroke of the piston; compared with the prior art, the time for impact compression and return of the piston is shortened, the efficiency of generating water hammer impact is increased, and continuous and stable power output is generated.

[0037] Figure 1-Figure 4A power system of water hammer effect includes a pressure cylinder 12 connected to a pressure water pipe 17, a pressure branch pipe 15 is arranged on the pressure water pipe 17, a detonation valve 16 is installed on the pressure branch pipe 15, the pressure cylinder 12 is provided with a hollow chamber 19, a piston 25 is slidably installed inside the hollow chamber 19, a piston rod 26 is installed on the end of the piston 25 away from the pressure water pipe 17, the piston rod 26 penetrates to the outside of the pressure cylinder 12 and is slidably connected to the pressure cylinder 12, a loosening ring 21 is arranged in the hollow chamber 19, and a water leakage collecting ring 22 which is interconnected with the loosening ring 21 is provided with a water leakage port 13; a dense ring is arranged adjacent to the loosening ring 21, the dense ring is located on the inner wall of the cylinder body 10 and close to the pressure water pipe 17, and the piston 25 slides in a sealed manner when in contact with the dense ring.

[0038] The input end of the pressure water pipe 17 is connected to the pressure water source 14. When the water source is connected, the pressure water pipe 17 and the front part of the hollow chamber 19 will be filled with pressurized water. When the detonation valve 16 is opened to let out the pressurized water and then the detonation valve 16 is suddenly closed, an instantaneous pressure wave will be generated due to the inertia of the water flow. This pressure wave will impact the piston 25 and the pipe wall like a hammer, resulting in a water hammer effect. The generated water hammer effect impacts the piston 25, causing the piston to move quickly away from the pressure water pipe 17. When the piston moves to the position of the loose circle, the pressure water pipe 17 is opened. The pressurized water inside the pressure water pipe 17 and the hollow chamber 19 is quickly released from the loosening circle. At this time, negative pressure is generated at the front end of the pressure water pipe 17 and the hollow chamber 19, and the piston 25 and the piston rod 26 move toward the pressure water pipe 17 together; when the pressure inside the pressure water pipe 17 and the hollow chamber 19 is greater than the bearing capacity of the piston 25, the piston 25 moves in the direction away from the pressure water pipe 17, and reciprocating motion is generated over and over again. The present invention can continuously and effectively impact the piston 25, and the piston rod 26 can convert the reciprocating linear motion into circular motion, thereby further driving the generator to generate electricity.

[0039] The inventor has been exploring the road to further develop natural water energy for more than ten years: since the broken faucet phenomenon was seen in early 2014, he has been thinking and brewing new methods to extract water energy, "vibration hydroelectric power generation technology" in 2017, "a water energy conversion device" in 2019, and until today, recording the process from infancy to growth and maturity, and it has been a difficult journey. After more than ten years of exploration, the most promising direction of developing water hammer power has been identified. It is hoped that just like people saw the phenomenon of boiling water and invented the steam engine, it can provide modern equipment for the development of natural water energy.

[0040] For the water hammer phenomenon to become a driving force, it must be solved that effective impact can occur continuously. There are two problems in this: one is "continuous"; the other is "effective impact". Continuity is the foundation. Without continuity, there is no condition for it to be a driving force. And effective impact is the root of the value of being a driving force. Only when it can be effectively impacted can it have the great value of becoming a driving force. The water hammer phenomenon caused by a broken faucet can cause the whole building to be restless with only 1.5 grams of water discharged per vibration. How is such a high-efficiency vibration effect achieved? After continuous observation and continuous thinking, the inventor realized the "leakage drainage technology" solution, which solved the problem of continuous effective impact. Many times, "seeing" does not produce much value, and "understanding" is the source of creativity.

[0041] The manifestation of water hammer power is intermittent impact phenomenon, which obtains power in waves. Water hammer needs to be vented after impact. Without venting, there will be no next round of impact. How does the present invention solve the problem of venting water hammer power? For a clear explanation, the following is a comparison with a gas piston:

[0042] Gas pistons generate power through explosions, and water hammer generates energy through collisions. Although the two are not exactly the same, both explosions and collisions are instantaneous explosions. Instantaneous explosions must be released after generating energy before the next round of perfect explosions can occur. However, the difference between water hammer power and gas pistons is that gas pistons are fuel oil, and only after exhausting the exhaust gas can there be the next round of full explosions. Exhausting the exhaust gas is the way for gas pistons to vent. The water hammer phenomenon is different. If it is exhausted, where will the collision come from? This is a contradiction. If it is not exhausted, there will be no next collision. If it is exhausted, there will be no chance of collision this time. What should I do? The solution is the leakage drainage method. Why use the leakage method? Water hammer power is generated by collision. The more you drain, the less power you can get. Therefore, it is the key to master the water hammer power technology to obtain as much energy as possible from the water hammer and to vent the water hammer to a certain extent. The leakage drainage technology can solve the release problem without affecting the impact strength of the water hammer.

[0043] The present invention can achieve both continuous and effective impact through the leakage type drainage technology, and the key to this is the double-layer design inside the pressure cylinder 12.

[0044] The pressure cylinder 12 includes two parts, a compact ring and a loose ring. The compact ring is set at the front end of the pressure pipe (the compact ring is the part on the inner wall of the cylinder body 10 close to the pressure water pipe 17). It is relatively short and its function is to better convert the energy generated by the water hammer into the power to push the piston. Next is the loose ring, which is much longer than the compact ring. It extends from the rear end of the compact ring to the second position where the piston moves. Its annular structure is slightly larger than the compact ring.

[0045] The loosening ring is the soul of the "leakage drainage technology". Its secret lies in the structure, which affects the conversion rate of water hammer energy. On the surface, the energy generated by the water hammer can be used as the power to push the piston under the action of the dense ring. However, if the loosening ring is not checked, the actual power obtained will be greatly reduced, and it will also affect the energy generated by the next round of water hammer. Therefore, the design of the loosening ring plays a decisive role in the function of the entire device. This requires the tightness between the piston and the pressure pipe to be properly handled. If it is too tight, the leakage effect cannot be achieved. If it is too loose, water leakage will occur when it should not leak. Therefore, it is necessary to ensure that the device will not leak under normal water pressure, and will only leak and discharge when the water hammer hits. In this way, the energy generated by the water hammer can be effectively converted into power, and the effect of releasing the water hammer energy can be achieved.

[0046] The looseness of the loose circle is relative, and is compared with the density of the dense circle. This design is inspired by the water hammer phenomenon of a broken faucet (the broken faucet is still preserved). The broken faucet is like this. It does not leak water under normal circumstances. Only when the water source is turned on and suddenly closed, a very small amount of water will leak out when it is hit by the water hammer. This does not affect the acquisition of the energy generated by the water hammer, but also allows the energy generated by the water hammer to be released to a certain extent, creating conditions for the next round of impact.

[0047] Regarding the drainage method during the operation of the piston, the piston is hit by the water hammer effect and starts to move from the first position. Initially, the piston is in the dense circle in the pressure cylinder. At this time, no matter how the water hammer is squeezed, no leakage will occur. However, the dense circle is relatively short, and the piston quickly enters the loose circle. The looseness of the loose circle is relative, relative to the density of the dense circle. Under normal circumstances, normal water pressure is not enough to cause leakage in the loose circle. However, only a small amount of water is squeezed out under the impact of the water hammer energy. Because the amount discharged is very small, the energy generated by the water hammer can be obtained to the maximum extent. This is the secret of the present invention that can obtain efficient water hammer energy. More importantly, the discharge of this small amount of water is enough to release the energy generated by the water hammer, because this release allows the water body near the piston to be in a relaxed state, creating good conditions for the effective impact of the next round of water hammer.

[0048] Furthermore, the pressure cylinder 12 includes a cylinder head 11 and a cylinder body 10 , and the cylinder head 11 and the cylinder body 10 are connected via cylinder bolts 29 .

[0049] Figure 2 and Figure 3 As shown in FIG. 1 , the inner diameter of the cylinder head 11 is smaller than the diameter of the piston 25, and the front chamber of the hollow chamber 19 is located inside the cylinder head 11. The cylinder bolt 29 passes through the cylinder head hole 27 and connects to the cylinder body hole 28, which is convenient for disassembly and installation of the pressure cylinder 12 and replacement of components inside the pressure cylinder 12.

[0050] Furthermore, the hollow chamber 19 includes a stroke chamber 20, a drain chamber and a stroke chamber 23 connected in sequence, the drain chamber includes a loose ring 21 surrounding the piston 25, and the loose ring 21 releases the pressurized water inside the drain chamber; a dense ring is arranged on the inner wall of the hollow chamber adjacent to the loose ring 21, the diameter of the stroke chamber is smaller than the diameter of the piston 25, the piston 25 is slidingly arranged in contact with the dense ring, the diameter of the loose ring 21 is larger than the diameter of the dense ring, and the piston 25 reciprocates inside the stroke chamber 23.

[0051] Figure 2 and Figure 3 As shown in the figure, the diameter of the loose ring 21 is larger than the diameter of the piston 25, and the inner walls of the cylinder body 25 located on both sides of the loose ring 21 and the water drainage collection ring 22 are tightly fitted and slidably arranged with the piston 25. When the end of the piston 25 moves to the position of the loose ring 21, the pressurized water is discharged from the water drainage port 13 connected to the loose ring 21; when the end of the piston 25 leaves the position of the loose ring 21, that is, the end of the piston 25 is closely fitted with the inner wall of the cylinder body 10, the piston 25 prevents the water in the pressure water pipe 17 from flowing out, and maintains a sealed state.

[0052] The cylinder body 10 includes a compact ring (the compact ring is the part between the displacement loose ring and the cylinder head 11 on the inner wall of the cylinder body 10), which is closely fitted with the piston 25 and is relatively short, and its function is to convert the energy generated by the water hammer into the power to push the piston. Next is the loose ring, the axial length of which is greater than 3 times the axial length of the compact ring, extending from the rear end of the compact ring to the second position where the piston moves, and its annular structure is greater than the diameter of the compact ring.

[0053] Further, the drainage chamber includes a loosening ring 21 and a drainage collection ring 22 which are connected to each other, and one end of the loosening ring 21 adjacent to the stroke chamber 20 maintains a relative distance from the end of the piston 25, and the diameter of the drainage collection ring 22 is larger than the diameter of the loosening ring 21. Further, a drainage port 13 is provided at the bottom of the drainage collection ring 22.

[0054] Figure 2 , Figure 3 and Figure 4As shown in the figure, the loose ring 21 is arranged close to the outer wall of the piston 25, and the loose ring 21 is arranged along the axial direction of the piston 25; the water leakage collection ring 22 is communicated with the loose ring 21, and the diameter of the water leakage collection ring 22 is larger than the loose ring 21, and the water leakage collection ring 22 can quickly collect the water leaked from the loose ring 21; in the present invention, the loose ring 21 is set to be narrow and long, which is conducive to the stable and long-term water leakage at the loose ring 21 during the compression of the piston 25, thereby increasing the stroke of the piston 25 on the loose ring 21; during the drainage of the loose ring 21, the water film is always attached between the piston 25 and the cylinder body 10, preventing external air from entering the inside of the pressure water pipe 17, which is conducive to the reciprocating motion of the piston 25.

[0055] Furthermore, a plurality of blind holes 30 are formed in the stroke chamber 23 at the end away from the piston 25 , and a spring 24 is installed inside the blind hole 30 , and the spring 24 abuts against the piston 25 .

[0056] Figure 4 As shown in , a plurality of blind holes 30 are provided inside the stroke chamber 23 , and a spring 24 is installed inside the blind hole 30 . The blind hole 30 limits the spring 24 , thereby preventing the spring from generating radial displacement or excessive bending, which would affect the reciprocating motion of the piston 25 .

[0057] Furthermore, the free end of the piston rod 26 is connected to a crankshaft via a connecting rod, and the crankshaft is connected to a generator (not shown).

[0058] The piston 25 and the piston rod 26 generate reciprocating motion together, and the piston rod 26 can be converted into circular motion through the connecting rod and the crankshaft, and the continuous circular motion is then converted into kinetic energy through the generator.

[0059] Furthermore, the pressure water pipe 17 and the cylinder head 11 are sealed and fixedly connected via a flange 18 .

[0060] Figure 1 and Figure 2 As shown in FIG. 1 , a sealing gasket (not shown) is provided at the connection between the flange 18 and the cylinder head 11 to facilitate the smooth passage of pressurized water.

[0061] Furthermore, the input end of the pressure water pipe 17 is connected to the high-pressure water interface 14 .

[0062] Figure 1 As described in the above, the high-pressure water interface 14 can be a pressurized water source or a water source falling from a high place, which generates pressure inside the pressure pipe and is conducive to generating a water hammer effect.

[0063] Furthermore, the detonation valve 16 is a fast-closing butterfly valve, a gate valve, or an electromagnetic shut-off valve.

[0064] Figure 1In the water hammer effect, stopping the flowing pressure water suddenly is an important condition for starting the water hammer effect; the detonation valve 16 adopts a fast-closing butterfly valve, a gate valve, or an electromagnetic cut-off valve, preferably a gate valve.

[0065] After the detonation valve 16 is opened, it is suddenly closed. At this time, the water flow is suddenly cut off, which causes the water hammer phenomenon. The water hammer hits the piston 25, and the piston 25 moves from the first position (the end of the piston 25 is close to the cylinder head 11) to the second position (the end of the piston 25 is away from the cylinder head 11). According to the principle of mechanics, the greater the impact force, the greater the reaction force will be. The reaction force acts on the water body, and while instantly preventing the subsequent water pressure from advancing forward, it drives the piston back to the first position. At the same time, after completing a round of impact, the water hammer puts the device in a short state of no force. In this way, even if the piston 25 is on the loose circle of the second position, the contact between the piston 25 and the pressure cylinder 12 is relatively close, and the sealing effect of the residual water between the piston 25 and the cylinder body 10 is sufficient to prevent the outside air from entering the cylinder body 10. According to the principle of vacuum science, the piston 25 at this time will be tightly adsorbed on this water body and move back to the first position with this water body.

[0066] Water still has an important characteristic that is often overlooked: after the water in the container is hit against one side of the container wall by an external force, it will drift in the opposite direction. This is the "reverberation" of water. The reverberation of water is very important, and it helps the piston return to the first position. Therefore, the piston 25 moves back from the second position to the first position due to the combined effect of multiple factors, so that the piston 25 can successfully complete the process of moving back.

[0067] The piston 25 moves back to the first position, at which time the water phenomenon disappears, and the subsequent high water pressure hits the piston 25 again, causing the water hammer impact to occur again, and this reciprocating process continues, and the device can operate normally.

[0068] The energy generated by the water hammer effect is very powerful, up to 200 times the original water pressure. In the present invention, the water hammer effect is made both "continuous" and "effectively impacting". The water inside the pressure pipe is not transported or used for other purposes, but only to generate the water hammer effect and impact the piston. From the perspective of energy conversion, the present invention has a higher energy utilization rate and makes the piston more efficient in generating reciprocating motion.

[0069] The present invention illustrates the technical concept of the present invention through the above embodiments, but the present invention is not limited to the above embodiments, that is, it does not mean that the present invention must rely on the above embodiments to be implemented. Those skilled in the art should understand that the relevant improvements to the present invention fall within the protection scope and disclosure scope of the present invention.
