Description

A water hammer effect power system TECHNICAL FIELD

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

[0002] The earth is very rich in water resources, nearly 70% of the surface is covered by water, but the water power generation is less than 17% of the total global power generation. The traditional water power generation has the characteristics of high water level and large flow, and the construction of dam becomes a necessary procedure, but how many places can we build dams? The construction of dam needs a large amount of manpower, financial resources, material resources and a long construction period, which causes irreparable great impact on the environment. The traditional water power generation needs state-level or huge financial groups due to the extremely large cost and great construction difficulty. The above factors are deadlocks, which seriously hinder the further development of water power generation.

[0003] The present invention of "a water hammer effect power system" opens up a broad prospect for further development of natural water energy, which is inspired by the water hammer phenomenon of a broken faucet.

[0004] More than ten years ago, the kitchen faucet of the inventor's home was broken. After turning off the water source, the faucet emitted a strong vibration accompanied by a small amount of dripping water, the vibration spread throughout the building along the pipe hanging on the outer wall, especially in the night and early morning. After repeated observation, it was found that the vibration and water leakage occurred after the water source was suddenly turned off, if the water source was slowly turned off, this phenomenon would not occur, which obviously was the "water hammer phenomenon", and the 38g faucet accessories were subjected to the impact of water hammer.

[0005] Water hammer phenomenon: the front of the water flow in the pipe is suddenly blocked, and the water behind continues to press forward, which will produce an impact force of tens to hundreds of times of normal water pressure. The water hammer phenomenon of the broken faucet is a demonstration of another way to obtain natural water energy from nature.

[0006] The inventor repeatedly observed and tested the phenomenon of the broken faucet, and found that it was very stable. In three tests, the water discharge collected by one hundred vibrations was 150g, 150g and 130g respectively, and the average water discharge per vibration was 1.5g. The 1.5g water discharge can make the whole building restless, which is the powerful power of water hammer energy.

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

[0008] Many people are also full of expectations for the energy generated by water hammer phenomenon, and there are some records in patent literature data, but so far no one has been able to demonstrate the basic conditions for making water hammer effect have the power of power. If the water hammer energy obtained is low, there is no value in further development as a power source.

[0009] 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", and the other is "effective impact". Continuous is the basis, and without continuous, there is no power condition. Effective impact is the fundamental value of power, and only effective impact has the great value of becoming a power source. Water hammer effect can produce energy up to 200 times the original water pressure, and if we can make water hammer effect produce energy 30-40 times the original water pressure with an acquisition rate of 70-80%, it has great value in developing into a power source, which is the connotation of effective impact. Whether it is the energy generated by water hammer effect or the acquisition rate, it will continue to improve with technological progress.

[0010] The water hammer phenomenon of a bad faucet can cause the entire building to be in an uproar with only 1.5 grams of water per vibration. With a 1.5 gram displacement per vibration, the faucet fittings can be impacted by 38 grams. How can such a high-efficiency vibration effect be achieved? The inventor has observed and thought constantly and has realized the "leakage type drainage technology" solution, which solves the problem of continuous and effective impact. This has found a high-efficiency, simple and inexpensive method for further development of natural water power, and future hydroelectric power generation will become a project that general enterprises can undertake.

[0011] There are many places in nature with a large drop but no dam conditions, or high water levels but not so much flow, which are good places for water hammer power devices to flourish. There is no need to build a dam, and the main infrastructure is to lay pipes, which can save a lot of manpower, financial resources, material resources and construction period, and has minimal impact on the environment. The current rise of pumped storage power generation can be increased by tens of times if water hammer power devices are used. Based on pumped storage, a pit can be dug anywhere with water to generate electricity. Based on pumped storage, any place with a certain amount of water can obtain a continuous source of power.

[0012] The water hammer effect in the prior art has low efficiency and cannot form continuous and stable power output. SUMMARY

[0013] In view of the deficiencies in the prior art, the water hammer effect power system is provided, which releases pressure water in the system after the loose ring and the water release collection ring on the inner wall of the cylinder release water and pressure, so that the piston quickly returns to the position without impact and compression, and then enters the next compression stroke of the piston.

[0014] In order to achieve the above-mentioned purpose, the technical scheme is adopted as follows:

[0015] The water hammer effect power system comprises a pressure cylinder connected with a pressure water pipe, a pressure branch pipe is arranged on the pressure water pipe, an explosion valve is installed on the pressure branch pipe, the pressure cylinder is provided with a hollow chamber, a piston is slidably installed in the hollow chamber, a piston rod is installed on the end of the piston away from the pressure water pipe, the piston rod penetrates to the outside of the pressure cylinder and is slidably connected with the pressure cylinder, a water release cavity is arranged in the hollow chamber, the water release cavity comprises a loose ring and a water release collection ring, a water release opening is formed in the water release collection ring, a dense ring is arranged close to the loose ring, the dense ring is arranged on the inner wall of the cylinder body and close to the pressure water pipe, and the piston is in sealing sliding contact with the dense ring.

[0016] As a preferred technical scheme of the present application, the pressure cylinder comprises a cylinder cover and a cylinder body, and the cylinder cover and the cylinder body are connected by cylinder bolts.

[0017] As a preferred technical scheme of the present application, the hollow chamber comprises a stroke cavity, a water release cavity and a stroke cavity connected in sequence, and the water release cavity comprises a loose ring surrounding the piston; the diameter of the stroke cavity is smaller than the diameter of the piston, the diameter of the loose ring is greater than the diameter of the piston, and the piston reciprocates in the stroke cavity.

[0018] As a preferred technical scheme of the present application, the loose ring comprises a loose ring and a water release collection ring in communication with each other, one end of the loose ring close to the stroke cavity is kept at a relative distance from the end of the piston, and the diameter of the water release collection ring is greater than the diameter of the loose ring.

[0019] As a preferred technical scheme of the present application, a water release opening is formed in the bottom of the water release collection ring.

[0020] As a preferred technical scheme of the present application, a plurality of blind holes are formed in the end of the stroke cavity away from the piston, springs are installed in the blind holes, and the springs abut against the piston.

[0021] As a preferred technical scheme of the present application, the free end of the piston rod is connected to the crankshaft through a connecting rod, and the crankshaft is connected to the generator.

[0022] As a preferred technical scheme of the present application, the pressure water pipe and the cylinder cover are sealingly and fixedly connected through a flange plate.

[0023] As a preferred technical scheme of the present application, the input end of the pressure water pipe is connected to a high-pressure water interface.

[0024] As a preferred technical scheme of the present application, the detonation valve is a quick-closing butterfly valve, a gate valve, or an electromagnetic cut-off valve.

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

[0026] 1、In the present application, a pressure water source is connected to the input end of the pressure water pipe, and the front part of the hollow chamber is filled with water having pressure; when the detonation valve is opened to flow out the pressure water and then suddenly closed, due to the inertia of the water flow, a transient pressure wave is generated, which will impact the piston and the pipe wall like a hammer, generating a water hammer effect; the generated water hammer effect impacts the piston, so that the piston moves rapidly away from the pressure water pipe; when the piston moves to the position of the loose ring, the pressure water in the pressure water pipe and the hollow chamber rapidly leaks out of the loose ring; at this time, negative pressure is generated at the front end of the pressure water pipe and the hollow chamber, and under the auxiliary action of the spring, the piston and the piston rod move together towards the pressure water pipe; when the pressure in the pressure water pipe and the hollow chamber is greater than the bearing capacity of the piston, the piston moves away from the pressure water pipe, and the above actions are repeated to generate reciprocating motion; the piston rod generates stable linear reciprocating motion along with the piston, which is beneficial to generate stable kinetic energy output. The function of the special structure of the loose ring in the present application can maximize the energy generated by the water hammer, so that the water hammer effect has the condition of becoming continuous and stable power.

[0027] In the present application, the water hammer phenomenon is caused by the sudden closing of the detonation valve after opening, the water hammer hits the piston, and the piston moves from the first position (the end of the piston is close to the cylinder cover) to the second position (the end of the piston is away from the cylinder cover). According to the principle of mechanics, the greater the impact force, the greater the opposite force, which acts on the water body and prevents the subsequent water pressure from advancing while driving the piston to move back to the first position. At the same time, the water hammer makes the device in a state of no force after a round of impact, so even if the piston is on the loose ring in the second position, the contact between the piston and the pressure cylinder is relatively close, and the residual water between the piston and the cylinder body is enough to prevent air from entering the cylinder body. According to the principle of vacuum, the piston will be tightly attached to the water body and move back to the first position. In addition, the water in the container will drift in the opposite direction after being hit by the external force against the container wall, which is the "reverberation" of water, which helps the piston to return to the first position. Therefore, the piston moves back to the first position from the second position, which is the combined effect of multiple factors, allowing the piston to smoothly 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 to hit again. This continues, and the device produces continuous and stable power output.

[0028] 2、The loose ring of the water discharge chamber in the present application is adjacent to one end of the stroke chamber and maintains a relative distance from the end of the piston, the diameter of the water discharge collection ring is greater than that of the loose ring, and the bottom of the water discharge collection ring is provided with a water discharge port. The loose ring is arranged close to the outer wall of the piston and is arranged in the axial direction of the piston; the water discharge collection ring communicates with the loose ring, and the diameter of the water discharge collection ring is greater than that of the loose ring, so that the water discharge collection ring can quickly collect the water discharged from the loose ring;

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

[0037] In Figures 1-4, a water hammer effect power system includes a pressure cylinder 12 connected with a pressure water pipe 17, the pressure water pipe 17 is provided with a pressure branch pipe 15, the pressure branch pipe 15 is installed with a detonation valve 16, the pressure cylinder 12 is provided with a hollow chamber 19, the hollow chamber 19 is slidably installed with a piston 25, the piston 25 is installed with a piston rod 26 at an end away from the pressure water pipe 17, the piston rod 26 penetrates to the outside of the pressure cylinder 12 and is slidably connected with the pressure cylinder 12, the hollow chamber 19 is provided with a loose ring 21, a water collection ring 22 in communication with the loose ring 21 is provided with a water outlet 13; a dense ring is provided adjacent to the loose ring 21, the dense ring is located on the inner wall of the cylinder body 10 and is close to the pressure water pipe 17, the piston 25 is in sealing sliding contact with the dense ring.

[0038] Wherein, the input end of the pressure water pipe 17 is connected with the pressure water source 14, when the water source is connected, the front part of the hollow chamber 19 is filled with water with pressure; when the detonation valve 16 is opened to flow out the pressure water, and then suddenly closes the detonation valve 16, due to the inertia of the water flow, a transient pressure wave is generated, which will impact the piston 25 and the pipe wall like a hammer, and the water hammer effect is generated; the generated water hammer effect impacts the piston 25, so that the piston moves away from the pressure water pipe 17, when the piston moves to the position of the loose ring, the pressure water in the pressure water pipe 17 and the hollow chamber 19 is quickly discharged from the loose ring, at this time, the front end of the pressure water pipe 17 and the hollow chamber 19 generates negative pressure, and the piston 25 and the piston rod 26 move together towards the pressure water pipe 17; when the pressure in the pressure water pipe 17 and the hollow chamber 19 is greater than the bearing capacity of the piston 25, the piston 25 moves away from the pressure water pipe 17, and the reciprocating motion is generated repeatedly, the piston 25 can be continuously and effectively impacted, and the piston rod 26 can convert the reciprocating linear motion into the circular motion, and further drive the generator to generate electricity.

[0039] The inventor has explored the way to further develop natural water energy for more than ten years: from 2014 to the present, the inventor has been thinking about a new method for extracting water energy since seeing the phenomenon of a bad water faucet, and has recorded the process from infancy to maturity, and has experienced hardships along the way. After ten years of exploration, the inventor has now determined that developing water hammer power is the most promising direction, and hopes to provide modern equipment for the development of natural water energy, just as people invented steam engines after seeing the phenomenon of boiling water.

[0040] In order to make the water hammer phenomenon into power, it is necessary to solve the problem of continuous and effective impact. There are two problems: one is "continuous", and the other is "effective impact". Continuity is the basis, and without continuity, there is no condition for power. Effective impact is the fundamental value of power, and only effective impact can have great value as power. The water hammer phenomenon of a bad water faucet can cause the whole building to be in an uproar with only 1.5 grams of water per vibration, and the 1.5 grams of water per vibration can impact 38 grams of water faucet accessories. How can such a high-efficiency vibration effect be achieved? The inventor has observed and thought constantly, and has realized the "leakage type drainage technology" scheme, which solves the problem of continuous and effective impact. Many times, "seeing" will not produce much value, and "enlightenment" is the source of creativity.

[0041] The water hammer power is expressed in the form of intermittent impact phenomenon, and the power is obtained in the form of wave by wave. The water hammer needs to be released after the impact, and there is no next round of impact without the release. How does the application solve the release problem of the water hammer power? To make it clear, the following compares the gas piston:

[0042] The gas piston generates power by explosion, and the water hammer phenomenon generates energy by impact. Although the two are not the same, both explosion and impact are instantaneous bursts. The instantaneous burst must be released after the energy is generated to have the next round of perfect burst. However, the water hammer power is different from the gas piston. The gas piston is fuel, and the exhaust gas is exhausted to have the next round of full explosion. Exhausting the exhaust gas is the release way of the gas piston. The water hammer phenomenon is different. If the exhaust is exhausted, where is the impact? This is a contradiction. Without exhaust, there is no next round of impact. Without the opportunity of this impact, how to do? The solution is to use a leaky drainage way. Why use a leaky drainage way? The water hammer power is generated by impact, and the more power obtained by the exhaust will be discounted. Therefore, as much as possible, the energy generated by the water hammer is obtained, and the water hammer is released to a certain extent. It is the key to master the water hammer power technology. Through the leaky drainage technology, the release problem can be solved, and the impact intensity of the water hammer is not affected.

[0043] The application can continuously form effective impact through the leaky drainage technology. The key to this is the double-layer design inside the pressure cylinder 12.

[0044] The inside of the pressure cylinder 12 includes two parts of the dense ring and the loose ring. The dense ring is arranged at the front end position of the pressure pipeline (the dense ring is the part of the inner wall of the cylinder body 10 close to the pressure water pipe 17), which is relatively short, and the function is to better convert the energy generated by the water hammer into the power to drive the piston. The loose ring is followed. The loose ring is much longer than the dense ring, and extends from the rear end of the dense ring to the second position of the piston movement. The annular structure of the loose ring is slightly larger than that of the dense ring.

[0045] The loose ring is the soul of the "leakage drainage technology", and its mystery lies in the structure, which affects the conversion rate of water hammer energy. On the surface, the energy generated by water hammer can become a better power to drive the piston under the action of the dense ring, but if the loose ring does not control, the real power obtained will be greatly discounted, and it will also affect the energy generated by the next round of water hammer. Therefore, the design of the loose ring plays a decisive role in the function of the whole device. It is necessary to handle the tightness between the piston and the pressure pipeline. If it is too tight, it will not achieve the effect of leakage, and if it is too loose, it will leak in the case where it should not leak. Therefore, it must be mastered that it will not cause the device to leak under normal water pressure, and only when the water hammer hits will it leak out. In this way, the energy generated by the water hammer can be effectively converted into power, and the effect of releasing water hammer energy can be achieved.

[0046] The looseness of the loose ring is relative, that is, relative to the tightness of the dense ring. The inspiration for this design comes from the water hammer phenomenon of a broken faucet (the broken faucet is still preserved). The broken faucet is like this. Under normal circumstances, it does not leak, and only when the water source is suddenly closed after being opened, it will leak out a small amount of water under the impact of water hammer. This does not affect the energy generated by the water hammer, and the energy generated by the water hammer is released to a certain extent, creating conditions for the next round of impact.

[0047] Regarding the drainage mode of the piston in operation, the piston is impacted by the water hammer effect and starts to move from the first position. At the beginning, the piston is in the dense ring in the pressure cylinder. At this time, no matter how the water hammer is pressed, it cannot leak. However, the dense ring is relatively short, and the piston soon enters the loose ring. The looseness of the loose ring is relative, that is, relative to the tightness of the dense ring. Under normal circumstances, normal water pressure is not enough to cause the loose ring to leak. However, under the impact of water hammer energy, a small amount of water is squeezed out. Because the amount of water discharged is very small, the energy generated by the water hammer can be maximized. This is the secret of the invention to obtain high-efficiency water hammer energy. More importantly, the discharge of this small amount of water is sufficient to release the energy generated by the water hammer, because this release puts the water near the piston in a relaxed state, creating good conditions for the effective impact of the next round of water hammer.

[0048] Further, the pressure cylinder 12 comprises a cylinder head 11 and a cylinder body 10, and the cylinder head 11 and the cylinder body 10 are connected by a cylinder bolt 29.

[0049] As shown in FIGS. 2 and 3, 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 connects the cylinder body hole 28 through the cylinder head hole 27, which is beneficial to the disassembly and installation of the pressure cylinder 12 and the replacement of the components inside the pressure cylinder 12.

[0050] Further, the hollow chamber 19 comprises a stroke chamber 20, a water release chamber and a stroke chamber 23 connected in sequence, the water release chamber comprises a loose ring 21 surrounding a piston 25, the loose ring 21 releases the pressure water inside the water release chamber; a compact ring is arranged on the inner wall of the hollow chamber close to the loose ring 21, the diameter of the stroke chamber is smaller than the diameter of the piston 25, the piston 25 is arranged in close sliding contact with the compact ring, the diameter of the loose ring 21 is larger than the diameter of the compact ring, and the piston 25 reciprocates inside the stroke chamber 23.

[0051] As shown in FIG. 2 and FIG. 3, the diameter of the loose ring 21 is larger than the diameter of the piston 25, the inner wall of the cylinder body 10 on both sides of the loose ring 21 and the water release collection ring 22 is arranged in close sliding contact with the piston 25, when the end of the piston 25 is displaced from the position of the loose ring 21, the pressure water is discharged from the water release port 13 connected with the loose ring 21; when the end of the piston 25 is away from the position of the loose ring 21, that is, the end of the piston 25 is in close contact 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 the sealing state.

[0052] The cylinder body 10 comprises a compact ring (the compact ring is the part between the displacement loose ring on the inner wall of the cylinder body 10 and the cylinder cover 11), the compact ring is arranged in close contact with the piston 25, and is relatively short, and the function is to convert the energy generated by the water hammer into the power for driving the piston. Then, the loose ring is arranged, the axial length of the loose ring is greater than 3 times the axial length of the compact ring, and the ring structure of the loose ring extends from the rear end of the compact ring to the second position of the piston movement, and the diameter of the ring structure is greater than the diameter of the compact ring.

[0053] Further, the water release chamber comprises the loose ring 21 and the water release collection ring 22 connected with each other, the end of the loose ring 21 close to the stroke chamber 20 is kept at a distance from the end of the piston 25, and the diameter of the water release collection ring 22 is greater than the diameter of the loose ring 21. Further, the bottom of the water release collection ring 22 is provided with the water release port 13.

[0054] As shown in FIG. 2, FIG. 3 and FIG. 4, the loose ring 21 is arranged in close contact with the outer wall of the piston 25, and the loose ring 21 is arranged in the axial direction of the piston 25; the water release collection ring 22 is communicated with the loose ring 21, and the diameter of the water release collection ring 22 is greater than the diameter of the loose ring 21, so that the water release collection ring 22 can quickly collect the water released from the loose ring 21; in the present application, the loose ring 21 is arranged to be long and narrow, which is beneficial to the stable and long-time water release of the loose ring 21 during the compression of the piston 25, and increases the stroke of the piston 25 on the loose ring 21; during the water release of the loose ring 21, the water film is always attached between the piston 25 and the cylinder body 10, which prevents the external air from entering the inside of the pressure water pipe 17, and is beneficial to the reciprocating movement of the piston 25.

[0055] Further, the stroke cavity 23 is provided with a plurality of blind holes 30 at the end away from the piston 25, and a spring 24 is arranged in each blind hole 30 and abuts against the piston 25.

[0056] As shown in FIG. 4, the stroke cavity 23 is provided with a plurality of blind holes 30, and a spring 24 is arranged in each blind hole 30. The blind holes 30 limit the spring 24 to avoid radial displacement or excessive bending of the spring, which affects the reciprocating motion of the piston 25.

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

[0058] The piston 25 and the piston rod 26 together produce reciprocating motion, which is converted into circular motion by the connecting rod and the crankshaft, and the continuous circular motion is converted into kinetic energy by the generator.

[0059] Further, the pressure water pipe 17 is sealingly and fixedly connected to the cylinder cover 11 through a flange plate 18.

[0060] As shown in FIGS. 1 and 2, a sealing gasket (not shown in the figure) is arranged at the connection between the flange plate 18 and the cylinder cover 11, which facilitates the smooth passage of the pressure water.

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

[0062] As shown in FIG. 1, the high-pressure water interface 14 can be a source of pressurized water or a source of water falling from a high place, which generates pressure inside the pressure pipe and facilitates the generation of water hammer effect.

[0063] Further, the detonation valve 16 is a quick-close butterfly valve, a gate valve, or an electromagnetic cut-off valve.

[0064] In the water hammer effect, the sudden stop of the flowing pressure water is an important condition for starting the water hammer effect; the detonation valve 16 is a quick-close butterfly valve, a gate valve, or an electromagnetic cut-off valve, and the gate valve is preferred.

[0065] When the detonation valve 16 is opened and then closed suddenly, water hammer is caused by the sudden interruption of water flow, and the water hammer hits the piston 25, which moves from the first position (the end of the piston 25 is close to the cylinder cover 11) to the second position (the end of the piston 25 is away from the cylinder cover 11). According to the principle of mechanics, the greater the impact force, the greater the equal and opposite reaction force. The reaction force acts on the water body, and prevents the subsequent water pressure from advancing while driving the piston to move back to the first position. At the same time, the water hammer makes the device in a state of short-term stress after completing a round of impact. Even if the piston 25 is on the loose ring in the second position, the contact between the piston 25 and the pressure cylinder 12 is tight, and the residual water between the piston 25 and the cylinder 10 is enough to prevent air from entering the cylinder 10. According to the principle of vacuum, the piston 25 will be tightly adsorbed on the water body and move back to the first position.

[0066] Water has an important feature that is often overlooked: after being hit by an external force against the wall of the container, the water in the container will drift in the opposite direction, which is the "reverberation" of water. The reverberation of water is very important, which helps the piston to move back to the first position. Therefore, the movement of the piston 25 from the second position to the first position is the combined effect of multiple factors, which enables the piston 25 to smoothly complete the movement back.

[0067] The piston 25 moves back to the first position, and the water body disappears. The subsequent high water pressure hits the piston 25 again, causing water hammer to occur again. This process continues, and the device can operate normally.

[0068] The energy generated by the water hammer effect is very strong, with a maximum energy of 200 times the original water pressure. In the present application, the water hammer effect is continuous and effective, and the water in the pressure pipe is not transported or used for other purposes, but only for generating water hammer effect and hitting the piston. From the perspective of energy conversion, the energy utilization rate of the present application is higher, and the efficiency of the piston reciprocating motion is higher.
