Description

Sea wave power machine

One, the technical field

The invention mainly applies mechanical principle, hydraulic dynamics and power generation knowledge, in particular to the following wave power machine power generation system which takes the fluctuation of waves as power.

Second, background Art

The development of wave power technology has lagged far behind wind power technology because there is no adequate way to absorb and convert the kinetic energy of the waves into electrical energy.

The ocean occupies 71% of the earth's surface area, the energy of the ocean is much greater than that of wind due to the large density of the seawater (seawater density 1.02, air density 0.00129, 1.02/0.00129 ═ 790), the sea wave is a pure green energy source which is granted to our ' four nothing ' (gratuitous, endless, pollution-free and environmental destruction) by nature, and the energy of the sea wave is enough to meet the demand of human beings on the energy source.

Third, the invention

1. Floating disc type sea wave power machine

The power generation aims at solving the problem of utilization of sea waves, and a floating disc type sea wave power machine capable of fully utilizing sea wave energy is manufactured.

In order to achieve the purpose, a floating disc which floats on the sea surface is manufactured according to the Archimedes principle and the Pascal law, when sea waves come, the floating disc is subjected to buoyancy force to rise, and the buoyancy force is the weight of the seawater with the same volume which is discharged by the part submerged below the sea surface; when the sea wave leaves, the floating disc can fall down automatically due to the self weight. The buoyancy is used when ascending, the falling is self gravity, because of the surging of sea waves, under the dual action of buoyancy and self gravity, the floating plate will fluctuate continuously, a piston is connected with a piston rod below the floating plate, the piston is arranged in a fixed piston cylinder, due to the up-and-down motion of the floating plate, the piston can do up-and-down reciprocating motion in the piston cylinder, in order to make the motion form of the piston closer to a conventional reciprocating pump, namely, the pushing and pulling forces output outwards when ascending and descending are equal, the buoyancy received when ascending and the gravity received when descending are equal, the adjustment is carried out by increasing and decreasing the balance weight in the floating plate, so that the buoyancy is equal to 2 times of the sum of the weight of the floating plate, the balance weight, the piston weight and the piston rod weight, and the mathematical expression is as follows: the buoyancy is 2 (the weight of the floating plate + the counterweight + the weight of the piston rod + the weight of the piston), so that the floating plate type sea wave power machine has the advantages that: firstly, the fluctuation kinetic energy of sea waves is changed into a power source; secondly, the size of the floating disc is artificially designed, the size of the buoyancy can be completely set according to the requirement, the buoyancy is small and is a rubber ball, the buoyancy is large and is floating on the water surface, and the required buoyancy can be obtained only by reasonably arranging and matching mechanisms such as the floating disc, a piston and the like, so that enough energy can be obtained from sea waves; thirdly, the buoyancy of the mechanism is artificially set to be equal to 2 times of the self-gravity, so that the thrust and the pull of the floating disc on the piston are equal, and the mechanism can work as a common reciprocating pump.

2. Seawater pressurizer

The floating disc type sea wave power machine needs equipment matched with the floating disc type sea wave power machine to fulfill the aim of absorbing and converting energy, and in order to fully exert the efficiency of the equipment, the seawater pressurizing machine matched with the floating disc type sea wave power machine for pressurizing seawater is specially manufactured, and the function of the seawater pressurizing machine is to convert the kinetic energy of a piston into pressure energy.

The preparation method comprises the following steps: the sea wave pressurizer is characterized in that a valve group is composed of a one-way water inlet butterfly valve and a one-way water outlet ball valve, two groups are used, one group is arranged at the lower part of a piston cylinder of a floating disc type sea wave power machine, and the other group is arranged at the upper part of the piston cylinder.

The working principle is that the piston moves downwards: because the piston cylinder is fixed, the seawater at the lower part of the piston in the piston cylinder is pressed, under the action of pressure, the water inlet one-way butterfly valve at the lower part of the piston cylinder is closed, the one-way water outlet ball valve at the lower part of the piston cylinder is opened, the seawater at the lower part of the piston cylinder is squeezed out of the one-way water outlet ball valve by pressure, and the pressurized seawater is output to the output pipe; when the piston moves downwards, the seawater on the upper part of the piston cylinder forms negative pressure, under the action of the negative pressure, the one-way water inlet butterfly valve on the upper part of the piston cylinder is opened, the seawater enters the upper part of the piston cylinder, and the water outlet one-way ball valve is closed by the negative pressure; the result of the piston descending is: the seawater enters the upper part of the piston cylinder, and the lower part of the piston cylinder outputs the pressurized seawater outwards, namely pressure energy is output. Then the piston goes up: the seawater at the upper part of the piston in the piston cylinder is pressurized, under the action of the pressure, the water inlet one-way butterfly valve at the upper part of the piston cylinder is closed, the one-way water outlet ball valve at the upper part is opened, and the pressurized seawater is output to the output pipe from the one-way water outlet ball valve; the piston is when going upward, and the sea water of piston cylinder lower part forms the negative pressure, and under the negative pressure, the one-way butterfly valve of intaking of piston cylinder lower part is opened, and the sea water gets into piston cylinder lower part, and one-way ball valve of going out is closed, and the result that the piston went upward is like this: the seawater at the upper part of the piston cylinder is output under pressure, and enters the lower part of the piston cylinder. The end result from the heave of the float is: no matter the piston goes up or down, the seawater enters from the one-way water inlet butterfly valve, flows out from the one-way water outlet ball valve after being pressurized, and the pressurized seawater is output to the output pipe.

Due to the adjustment of the balance weight, the thrust and the pulling force on the piston are equal, the pressure transmitted to the seawater by the piston in the piston cylinder is equal, the sea wave is continuously generated at one time when the sea wave is endless, the system can continuously apply pressure to the seawater, and the seawater with constant pressure energy can be continuously output. The sea water pressurizer has the function of utilizing sea waves to continuously generate pressure energy and then utilizing the pressure energy to do work (generate electricity).

3. Hydraulic circulation

As described above, it can be seen from the working process of the sea wave pressurizer that, for seawater, pressure energy is applied to the seawater entering the piston cylinder, and energy is released to do work (generate electricity) after the seawater exits the piston cylinder, the amount of seawater in this process does not change, a certain amount of seawater enters the piston cylinder, an equal amount of seawater exits the piston cylinder, the amount of seawater in the working process after exiting the piston cylinder does not change, the seawater is only a carrier for energy transfer, and then the seawater in the whole process can be completely processed and then circulated in a closed manner, and even the seawater can be replaced by a special liquid in the system, for example: hydraulic oil in a hydraulic system, so that the system is not corroded and impurities cannot invade.

4. Piston type sea wave power machine

The mechanical energy output by the floating disc type sea wave power machine can be matched with other machines for use, so that the linear motion is changed into circular motion, and then the generator is driven to generate electricity. In order to facilitate use and expand the application range, the floating disc type sea wave power machine is simplified by combining a piston and a floating disc (containing a balance weight) into a whole, transplanting the functions of floating and balance weight adjustment of the floating disc to the piston, namely the floating disc type piston, namely the floating disc can be cancelled, directly installing the floating disc type piston in a piston cylinder, manufacturing the cylinder wall of the piston cylinder into a plurality of holes in order to ensure that the seawater can be more smoothly discharged and enters, and adjusting the buoyancy by using the balance weight to be like the floating disc type sea wave power machine, namely the piston type sea wave power machine.

5. Ratchet planetary machine

As mentioned above, the amount of fluctuation of sea waves is not ideally fixed, and there is uncertainty that it is difficult to form a circular motion with a fixed diameter in the process of converting the linear motion into mechanical rotation, which can be accomplished by mechanical conversion with variable diameter, such as: a gear lever simple pendulum mechanism mode, a head knocking machine mode and the like, but the controlled conditions are too many in use and are difficult to popularize. The special machine-ratchet planetary machine capable of overcoming the difficulties is specially developed and invented, and has the advantages that no matter the rack moves upwards or downwards, even if the stroke length is different, the linear motion can be completely and smoothly changed into circular rotation motion within the designed stroke. The preparation method comprises the following steps: a double-sided straight plate rack is arranged at the lower part of the piston, a ratchet group is respectively arranged at the left side and the right side of the rack, the ratchet group consists of a ratchet wheel and a gear, and an inner gear ring shared by the ratchet groups at the left side and the right side is arranged at the outer side of the ratchet groups at the left side and the right side, so that a ratchet planet wheel is formed; the working principle is as follows: when the rack moves upwards, the ratchet wheel on the left side rotates anticlockwise, the ratchet wheel is opened to drive the gear to rotate anticlockwise, the gear pushes the inner gear ring to rotate anticlockwise, the ratchet wheel in the ratchet wheel group on the right side rotates clockwise while the rack moves upwards, but the function of unidirectional torque transmission of the ratchet wheel is closed, so that the ratchet wheel idles, torque is not transmitted to the gear, the inner gear ring is shared by the left ratchet wheel group and the right ratchet wheel group, at the moment, the inner gear ring rotates anticlockwise under the action of the left ratchet wheel group, the inner gear ring acts on the gear of the right ratchet wheel group in a reaction mode, the gear of the right ratchet wheel group also rotates anticlockwise, but the function of the ratchet wheel in the right ratchet wheel group is closed, and the anticlockwise rotation of the system is not influenced, so that the rack moves upwards to. In the same way, the rack moves downwards, the working process of the left side ratchet wheel set is the same as that of the rack moving upwards, the same work doing method is repeated on the left side by the right side ratchet wheel set, and as a result, the inner gear ring of the ratchet planet wheel rotates anticlockwise. In this way, the shared inner gear ring is finally rotated anticlockwise no matter the straight plate rack moves upwards or downwards. The straight plate rack moves up and down, so that the left and right groups of ratchet wheels transmit torque alternately, the inner gear ring pauses instantly when the rack changes the movement direction, the stable operation of the system is influenced, and the pause phenomenon can occur when the torque is output outwards. A straight rod is arranged on the ratchet planet wheel and is connected with a generator through a wave spring ring, so that a power generation system taking wave fluctuation as power is formed, and the ratchet planet wheel machine is the ratchet planet wheel machine.

the fifth embodiment is as follows:

1. floating disc type sea wave power machine

The structure and the working principle of the power generation are described in the following with the attached drawings: as shown in fig. 1, a floating plate 4 is made, and in order to make the working state of the floating plate more ideal, the floating plate can work like a reciprocating pump, the sum of the self gravity of the system, which is 2 times the buoyancy force received by the floating plate, is designed, namely the buoyancy force is 2 (the weight of the floating plate + the weight of a counterweight + the weight of a piston rod + the weight of a piston), so as to ensure that the buoyancy force received by the floating plate 4 in the fluctuation of sea waves is equal to the gravity when the floating plate falls, and the method is to add a counterweight 5 in the floating plate 4 to adjust the above formula.

A piston rod 3 is arranged below the floating disc 4, a piston 2 is arranged below the piston rod 3, and the piston rod 3 and the piston 2 are arranged in the fixed piston cylinder 1. Therefore, due to the fluctuation of sea waves, the piston 2 can reciprocate up and down in the piston cylinder 1, and the mechanism which is composed of the floating disc 4, the balance weight 5, the piston rod 3, the piston 2 and the piston cylinder 1 is the floating disc type sea wave power machine. When the machine is placed in sea water, the machine can output power with equal thrust and pull force outwards like a reciprocating pump along with the fluctuation of sea waves.

2. Sea wave pressurizer

The method specially manufactures a seawater pressurizing machine matched with the floating disc type sea wave power machine, and comprises the following steps: a one-way water inlet butterfly valve 6 and a one-way water outlet ball valve 7 are used as a group, two groups are used, one group is arranged at the upper part of a piston cylinder 1 of a floating disc type sea wave power machine, the other group is arranged at the lower part of the piston cylinder 1, and then outlets of the two one-way water outlet ball valves 7 and inlets of the two one-way water inlet butterfly valves are respectively connected by pipelines, as shown in figure 2, the sea water pressurizer is the sea water pressurizer, and under the action of sea waves, the working principle is as follows: when the piston 2 moves upwards, negative pressure is formed in the piston cylinder 1 at the lower part of the piston 2, the negative pressure enables the one-way water inlet butterfly valve 6 to be opened, seawater enters the lower part of the piston cylinder 1, and the one-way water outlet ball valve 7 at the lower part of the piston cylinder 1 is closed; the piston cylinder 1 on the upper part of the piston 2 forms positive pressure, under the action of the pressure, the one-way water inlet butterfly valve 6 on the upper part of the piston cylinder 1 is closed, the one-way water outlet ball valve 7 is opened, and the pressurized seawater is extruded out of the piston cylinder 1 and is output to the connecting pipe. Then the piston 2 moves downwards, the piston 2 basically works in a reverse direction with the upward movement of the piston 2, and the seawater at the lower part of the piston cylinder 1 is pressurized, so that the one-way water outlet ball valve 7 at the lower part of the piston cylinder 1 is opened, the pressurized seawater is output through a connecting pipe outside the ball valve, and the pressure causes the one-way water inlet butterfly valve 6 at the lower part of the piston cylinder to be closed; meanwhile, negative pressure is formed on the upper portion of the piston cylinder 1, the negative pressure enables the one-way water inlet butterfly valve 6 on the upper portion of the piston cylinder 1 to be opened, seawater enters the piston cylinder 1, and the negative pressure enables the one-way water outlet ball valve 7 to be closed. The final result of the wave fluctuation motion is that no matter the piston 2 goes up or down, the result is that seawater enters the piston cylinder 1, and meanwhile, the seawater is extruded and then output through the output pipe, and the wave fluctuation is continuous, so that continuous pressurized seawater can be obtained, and the power can be used for power generation.

3. Piston type sea wave power machine

In order to enable the floating disc type sea wave power machine to be suitable for more occasions and more conveniently do work, the floating disc type sea wave power machine is improved in a simplified mode, namely the floating disc 4 and the piston 2 are combined, the floating and counterweight functions of the floating disc 4 are moved into the piston 2, the floating disc 4 is omitted, and the combined piston is the floating disc type piston 8, as shown in figure 4. In order to make the up-and-down reciprocating motion of the floating disc type piston smoother, the wall of the piston cylinder 1 is made into a porous piston cylinder 9, and the improved floating disc type wave power machine is a piston type wave power machine.

4. Ratchet planetary machine

The power output by the piston type sea wave power machine is an uncertain stroke and reciprocating linear motion, the uncertain stroke is because the fluctuation quantity of sea waves is not a fixed value, therefore, a set of ratchet planet wheels are manufactured and a generator is installed to form the ratchet planet machine which is specially used for power generation, and as shown in figure 4. Manufacturing a ratchet planet wheel: a straight plate double-sided rack 11 is connected below the piston 1, a ratchet wheel 12 is respectively arranged on the left and the right of the rack, each ratchet wheel is respectively provided with a gear 13 in a matched manner, a ratchet wheel set is formed by the ratchet wheel 12 and the gear 13, an inner gear ring 15 shared by the left and the right ratchet wheel sets is arranged on the outer side of the ratchet wheel set, the rack 11, the ratchet wheel 12 set and the inner gear ring 15 jointly form a ratchet wheel planet wheel, as shown in fig. 5, under the action of wave fluctuation, the wave comes, and the working process is promoted to be: the rack 11 moves upwards, the unidirectional torque transmission function of the left ratchet wheel 12 is started to drive the gear 13 to rotate counterclockwise together, the gear 13 pushes the inner gear ring 15 to rotate counterclockwise, the right ratchet wheel 12 is also acted by the rack 11 at the moment, but the unidirectional torque transmission function of the ratchet wheel 12 is closed, no torque is transmitted outwards, the inner gear ring 15 rotates counterclockwise, the inner gear ring 15 reversely pushes the right gear wheel 13 to rotate counterclockwise, the inner gear ring 15 rotates counterclockwise, the unidirectional torque transmission function of the right ratchet wheel 12 is closed, the inner gear ring 12 and the matched gear 13 idle relatively, no torque is transmitted, the mutual influence and the work of the inner gear ring 15 are not influenced, and the result that the inner gear ring 15 rotates counterclockwise when the rack 11 moves upwards is realized. And then the sea wave retreats, the working process of the sea wave retreats in the same working mode as that of the sea wave ascending, only the right-side ratchet wheel 12 group pushes the inner gear ring 15 to rotate anticlockwise when descending, and the right-side ratchet wheel 12 group pushes the inner gear ring 15 to rotate anticlockwise when descending. The end result is: the ratchet planet wheel enables the inner gear ring 15 to rotate anticlockwise no matter the sea wave starts to be in a volt state.

Because the rack 11 does reciprocating motion one above the other, the motion direction will be changed continuously, and as a result, the inner gear ring 15 will be stopped continuously in the rotation process, so that the system is not stable in operation, and the solution is: the connecting rod 10 for outputting torque externally is provided with a wave spring 14, and then is connected with a generator 16, and the wave spring 14 can absorb and relieve the pause phenomenon, namely a ratchet planetary machine, and can be used for generating power. Fig. 6 is a schematic diagram of a piston type wave power machine and a ratchet planetary machine combined for power generation. Of course, since the piston type wave power machine is a power source and can also drive other machines to convert kinetic energy into electric energy, fig. 7 is a schematic diagram of the piston type wave power machine and the gear lever simple pendulum mechanism combined to generate electricity.

The above description is only for the purpose of illustrating the general principles of the present invention, and is intended to cover such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
