Background
Ocean energy (including tidal energy, wave energy, ocean current energy and the like) is a clean and pollution-free renewable energy source, is abundant in reserves and wide in distribution, and has excellent development prospect and value. The ocean energy is mainly used for power generation, and the working principle of the ocean energy is similar to that of wind power generation, namely, the mechanical energy of seawater is converted into electric energy through an energy conversion device. Specifically, firstly, seawater impacts a water turbine, the water turbine captures kinetic energy of the seawater, then the kinetic energy of the seawater is converted into rotary mechanical energy, and the mechanical energy drives a generator to generate electricity through a mechanical transmission system, and finally the electricity is converted into electric energy.
In the last century, many large-scale enterprises in the world, including GE, lausley, altaston, siemens, germany, IHI, japan, and the like, have invested large amounts of manpower, material resources, and capital in the development of marine power generation. At present, the most advanced tidal current energy unit in the world is jointly developed by three international great heads of GE, Lauslesi and Alston, and the longest continuous power generation grid connection time is only 113 days.

Detailed Description
As shown in fig. 1, a first embodiment of the present invention provides an ocean power generating apparatus 100, which includes a first sealed cabin 1, a second sealed cabin 2, a horizontal axis hydraulic generator 3, an inspection and sealing system 4, and a braking system 5.
The first capsule 1 is rotatable and the second capsule 2 is stationary. Specifically, when the ocean power generating apparatus 100 is operated to generate power, the first sealed cabin 1 always rotates along with the hub 31, and when the ocean power generating apparatus 100 is to be overhauled, the first sealed cabin 1 stops rotating and enters a static state. The second sealed cabin 2 is in a relatively static state regardless of whether the ocean power generating apparatus 100 is operated or not. "stationary" in this application is a relative condition where sloshing up and down the apparatus caused by sea water shock is ignored.
The horizontal shaft hydro-generator 3 includes a hub 31 and a generator 32. In this embodiment, the hub 31 is located in the first sealed cabin 1, and the generator 32 is located in the second sealed cabin 2. In the present embodiment, the horizontal-axis hydro-generator 3 further includes a main shaft 33, i.e., a drive shaft. The main shaft 33 has one end connected to the hub 31 and the other end connected to the generator 32, and the main shaft 33 transmits mechanical energy generated by the hub 31 to the generator 32.
In this embodiment, ocean power generation facility 100 still includes installation axle 6, and the one end intercommunication second sealed cabin 2 of installation axle 6, the other end of installation axle 6 are located above the surface of water P, and maintainer or maintenance machine can directly enter into in the second sealed cabin 2 through installation axle 6. Specifically, the mounting shaft 6 has a certain inner diameter width to have a sufficient space so that a service person or a service machine can enter the second hermetic chamber 2 through the mounting shaft 6, and finally, inspection, maintenance (oil replacement), repair, or the like of the electrical components in the second hermetic chamber 2 is performed. In addition, the inside of the installation shaft 6 may be arranged with lines and drains.
In the embodiment, the gear box, the speed increasing box and the generator are uniformly distributed in the second sealed cabin 2 instead of the first sealed cabin 1, and one advantage is that the volume of the sealed cabin 1 is reduced as much as possible, so that the rotating resistance of the first sealed cabin 1 is smaller, and the kinetic energy capture rate of seawater is improved; the second benefit is that the reduction of the volume of the first sealed cabin 1 helps to improve the underwater pressure resistance and sealing performance of the first sealed cabin 1; the third benefit, because the high-speed shaft of the gear box connected with the generator is easy to wear, needs to be checked and replaced regularly, and the bearings used in the gear box, the speed increasing box and the generator also need to be replaced regularly, and for the electric parts which need to be overhauled regularly, the electric parts are arranged in the second sealed cabin 2, so that the maintenance is more convenient. Specifically, the maintenance personnel can directly enter the sealed cabin 2 from above the water surface through the installation shaft 6 for maintenance without entering the first sealed cabin 1 again. In particular, the related art that the service personnel can enter the first sealed cabin 1 is never disclosed in the prior art, so the prior art cannot allow the service personnel to enter the first sealed cabin for service, and only the device can be lifted out of the horizontal plane for service.
However, the present invention is not limited to the position of the generator 32. In other embodiments, the generator 32 may be disposed within the first capsule 1. In this case, the main shaft 33 having one end located in the first capsule and the other end located in the second capsule may be omitted. In another embodiment, the generator 32 may be disposed above the water surface, and the mechanical energy of the water turbine is transmitted to the generator 32 above the water surface in a manner of changing direction by 90 degrees through a variable angle transmission system (not shown), so that the maintenance is more convenient, and the maintenance difficulty and cost are reduced.
In the present embodiment, the horizontal axis hydro-generator 3 includes a plurality of blades 34. The blade is a core component of the water turbine for capturing ocean energy. The pitch angle of the blade can be adjusted, and the blade is divided into a fixed pitch and a variable pitch. The fixed pitch has the advantages of no pitch change and simple structure. However, the ocean energy has the periodic characteristics of reciprocation and flow rate change, and the fixed pitch has the defects of poor controllability, incapability of realizing high-school conversion and profit of the ocean energy and the like, so that the waste of ocean energy resources and the cost rise of the ocean energy power generation device are finally caused.
Compared with a fixed pitch, the variable pitch has two main advantages: firstly, according to the reciprocating characteristic of ocean energy, the pitch angle of the blade can be adjusted in real time, so that the blade is opposite to the incoming direction of tidal current to capture the maximum kinetic energy, the water turbine is easier to start, the starting flow rate is reduced, and the high-efficiency operation can be realized during the rising tide and the falling tide; and secondly, when the tidal current flow rate exceeds the rated flow rate, the pitch angle is adjusted to reduce the kinetic energy captured by the blades so as to ensure that the water turbine works efficiently (cannot exceed the load) under the rated power. In conclusion, the starting characteristic and the operation reliability of the ocean energy water turbine can be improved by adjusting the pitch angle, power can be generated in flood tide and tide, the working time in one tide period is prolonged, and the total energy obtaining efficiency and the power generation efficiency are improved.
In this embodiment, each blade 34 is pitch-variable connected to the hub 31, i.e. each blade 34 can rotate to the angle of the water surface according to the change of the water flow direction or speed, thereby increasing or adjusting the generated power. However, the present invention is not limited thereto. In other embodiments, the turbine may be a conventional horizontal axis turbine with blades that do not pitch.
With the need to adjust the pitch angle, it is necessary to provide a pitch system 35 (this element is shown simply in FIG. 1) within hub 31. The pitch system 35 is a core component of the entire generator set. The control system, the lubrication system and the like which are matched with the lubricating device all need to be maintained and repaired regularly. The seals of the blades also need to be replaced periodically to ensure safety. In the prior art, a part of ocean power generation devices directly operate without considering the problem, and finally the whole generator set can be scrapped in a short time. Some people pay attention to the problem, the generator set is lifted out of the sea periodically to be maintained and repaired, so that the cost is greatly increased, the power generation time is shortened, and the commercial application of the whole power generation device is finally influenced. In this embodiment, the pitch system 35 is located inside the first capsule 1.
As shown in fig. 2, in the present embodiment, the service sealing system 4 includes at least one gas filled seal 41 and at least one metal seal 42. By providing a metal seal instead of a rubber seal, the service life of the seals in the service seal system 4 is extended. The sealing performance is ensured by arranging at least two seals, so that the safety of maintainers is improved. Preferably, the inflatable seal 41 is multi-pass. The inflatable sealing material is made of high polymer materials, and each inflatable sealing is independently operated. When the maintenance sealing system 4 works, the plurality of inflatable seals are inflated respectively to be expanded to fit the sealing surfaces, so that a channel isolated from the outside seawater (namely, a third sealing cabin 8) is formed between underwater equipment. Then, the servomotor 421 attached to the metal seal is operated to drive the metal seal to reach a set position, so that the sealing performance of the third sealed cabin is further ensured. Even if the air-filled seal is used for a long time, the sealing performance is reduced, even the seal completely fails, but the isolation of the subsequent channel and the external seawater can be kept due to the existence of the metal sealing ring.
In this embodiment, the service seal system 4 is disposed in the second capsule 2. Since the second capsule 2 is closer to the control system on the water surface than the first capsule 1 and circuit arrangement is easier, it is more preferable that the service sealing system 4 is provided in the second capsule 2. However, the present invention is not limited thereto. In other embodiments, the service seal system 4 may be disposed within the first capsule 1. The control circuit can be arranged through the main shaft 33, so as to control the maintenance sealing system 4 in the first sealing chamber 1 to operate.
In this embodiment, the first capsule 1 has a first access door 11 and the second capsule 2 has a second access door 21. The first and second access doors 11 and 21 may be sized to allow an access person or an access machine to pass therethrough. An escalator or a step (not shown) for the maintainers to climb can be arranged between the access door and the bottom of the corresponding sealed cabin. When no service is required, both access doors are closed. The access door can be opened or closed by manual or automatic control, and the utility model discloses do not limit to this. In this embodiment, the first access door 11 corresponds to the second access door 21, so as to reduce the sealing space after the subsequent third capsule 8 is formed as much as possible, and reduce the sealing difficulty and requirement.
In this embodiment, the service seal system 4 is disposed at a specific position of the second capsule 2 such that the main shaft 33 between the second capsule 2 and the first capsule 1 is also located within the third capsule 8. Specifically, as shown in fig. 1, the service seal system 4 is disposed around the entire diameter of the second capsule 2 (the service seal system 4 is seen in a cross-sectional view at the uppermost and lowermost ends of the second capsule 2). Through the arrangement, after the maintenance sealing system 4 works, the main shaft 33 between the second sealed cabin 2 and the first sealed cabin 1 is also in a sealed environment, and a maintenance worker can replace the sealing ring on the main shaft 33 (if the main shaft 33 is not in the sealed environment, seawater can be filled from the main shaft 33 by directly replacing the sealing ring).
However, the present invention does not limit the installation position for repairing the sealing system 4. In a second embodiment, as shown in fig. 3, the service sealing system 4 may be arranged only one turn around the service door. Therefore, the space required to be sealed is reduced, and the sealing difficulty is reduced.
In this embodiment, the ocean power generating apparatus 100 further includes a drainage device 7, and when the service sealing system 4 is operated to form a third sealed compartment 8 between the first service door 11 and the second service door 21, the drainage device 7 is operated to drain water in the third sealed compartment 8. However, the present invention is not limited to this, and in other embodiments, if there is no drainage device 7, after the third sealed cabin 8 is formed, the second access door 21 is opened first, and the seawater in the third sealed cabin 8 will flow into the second sealed cabin 2 from the second access door 21. Since the volume in the second sealed cabin 2 is relatively large and the amount of seawater in the third sealed cabin 8 is not much, the influence is not great. Due to gravity, the seawater flowing into the second sealed cabin 2 will gather at the bottom (a water storage tank may be specially arranged or not). Can set up the water pump in addition in second sealed cabin 2, take out the sea water that flows into in second sealed cabin 2 and discharge more than the surface of water (the drain pipe is arranged through installation axle 6 inside).
In this embodiment, the braking system 5 includes an electric brake device 51 and a manual brake device 52, both located in the second sealed compartment 2. The positioning of the braking system 5 in the second capsule 2 is preferred, since the second capsule 2 is closer to the control system on the water surface than the first capsule 1 and the circuit arrangement is easier. However, the present invention is not limited thereto. In other embodiments, the manual brake device 52 may still be disposed in the second capsule 2, and the electric brake device 51 may be disposed in the first capsule 1. The control circuit may be inserted through the main shaft 1 to control the electric brake device 51 located in the first capsule 1 to operate.
In practice, the manual brake 52 may be a mechanical latch brake. The electric brake device 51 is operated by a brake to keep the transmission system (including the main shaft 33) stationary, so that the wheel hub 31 is kept stationary, and finally the first capsule 1 can be kept stationary. If the impact force of the water flow on the impeller is very large in a sea area where the water flow is very turbulent, this time corresponds to the pressure increase of the brake of the electric brake device 51, and when the pressure exceeds the braking force, the brake may be disabled, thereby causing the first capsule 1 to continue to rotate. If personnel enter the overhaul at this time, accidents can happen. In order to ensure the personal safety of the maintenance personnel, a manual braking device 52 is additionally arranged, and the first sealed cabin 1 can be kept in a static state when maintenance is carried out through a conventional mechanical mode.
In this embodiment, the ocean power generating apparatus 100 further includes an observation window 9, and the observation window 9 is disposed on the second sealed cabin 2 and is used for allowing a maintainer to observe whether the first sealed cabin 1 is stationary under the action of the braking system 5. Particularly, observation window 9 can set up in the one side of second sealed cabin 2 towards first sealed cabin 1 to make the maintainer can see directly perceivedly whether first sealed cabin 1 is still rotating, further improve maintainer's security, avoid the occurence of failure of braking system to endanger maintainer life safety's accident.
The maintenance method of the ocean power generation device according to the embodiment is specifically described below.
When the electrical components in the second sealed cabin 2 need to be overhauled, the searching personnel or the overhauling machine can directly enter the second sealed cabin 2 through the installation shaft 6 for overhauling. When electrical components in the first sealed cabin 1, such as a motor and a sealing ring of a pitch system, need to be overhauled, an overhaul person or an overhaul machine may enter the second sealed cabin 2 through the installation shaft 6. The electric brake device 51 is activated to start operating first, so that the rotating first capsule 1 is stationary. In order to ensure the safety of the service personnel, a double insurance is provided, and the service personnel then activate the manual braking device 52, further ensuring that the first capsule 1 does not suddenly rotate during the service.
The service person then observes through the observation window 9 to verify whether the first capsule 1 is really stationary. And after the stillness is confirmed, starting the maintenance sealing system 4. When the inflatable seal 41 and/or the metal seal 42 of the service seal system 4 are/is activated (both are activated to ensure the sealing performance), the drainage device 7 works to drain the seawater in the third sealed chamber 8. In particular, a part of the drain pipe of the drain device 7 may be provided as a sight pipe 71, and whether water flows in the drain pipe is observed through the sight pipe 71 to check whether the sea water is completely drained. After the air is completely exhausted, the first access door 11 and the second access door 21 are respectively opened, so that an overhaul person or an overhaul machine can enter the first sealed cabin 1 through the second sealed cabin 2 to overhaul. And after the maintenance is finished, closing the maintenance door, and also closing the braking system and the maintenance sealing system.
As shown in fig. 4, a third embodiment of the present invention provides an ocean power generating apparatus 300, which includes a first sealed cabin 1, a second sealed cabin 2, a horizontal axis hydraulic generator 3 ', a braking system 5 and a main shaft 33'. The first capsule 1, the second capsule 2 and the braking system 5 are shown in the first embodiment and will not be described in detail here. Only the differences will be described below.
In the third embodiment, one end of the main shaft 33 'is located in the first sealed cabin 1, the other end is located in the second sealed cabin 2, two access doors or two access ports 331, 332 are provided on the main shaft 33', and the two access doors or two access ports 331, 332 are located in the first sealed cabin 1 and the second sealed cabin 2, respectively. When the elements in the first sealed cabin 1 need to be overhauled, the brake system 5 works to make the rotating first sealed cabin 1 static, and an overhaul person or an overhaul machine penetrates into the first sealed cabin 1 from the second sealed cabin 2 through the inside of the main shaft 33' for overhauling. By providing a main shaft 33' that can be passed by a service person, the provision of a service seal system can be eliminated. The structure is simpler, the installation difficulty is lower, and the cost is reduced. In addition, in the present embodiment, the generator portion of the horizontal axis hydro-generator 3' may be located in the first containment chamber 1 instead of the second containment chamber 2.
The utility model discloses the relevant characteristic in the embodiment of each application can carry out the independent assortment combination according to actual need, and these are all in the utility model discloses the within range that will protect. For example, the ocean power generation device 300 in the third embodiment may also have the service sealing system 4 in the first embodiment, and although in the ocean power generation device 300, a service person does not need to enter the first sealed cabin through the service door in the first embodiment, by providing the service sealing system 4, the main shaft between the two sealed cabins is in a sealed environment after the service sealing system 4 works, and the service person may also replace the sealing ring on the main shaft.
The problem of sealing is a crucial issue for the long term stable and efficient power generation of marine power generation devices, but is easily ignored by those skilled in the art. Because the prior art can not consider that the maintainer enters the water to directly overhaul, the problem of replacing the sealing element under the water is never considered. In the prior art, after the sealing element is used for a period of time, the whole ocean power generation device needs to be lifted above the water surface periodically (for example, 6 months), so that the sealing ring is completely replaced.
The utility model discloses a marine energy power generation facility pioneering ground lets maintainer or machine, can enter into first sealed under-deck through the second sealed under-deck, overhauls the components and parts in the first sealed under-deck, for example change the sealing element in the first sealed under-deck, the motor in the first sealed under-deck is maintained or is changed machine oil etc.. The problem that in the prior art, a person skilled in the art neglects to overhaul the electronic components in the first sealed cabin underwater is solved, and the defect that in the prior art, the whole ocean energy power generation device must be lifted out of the sea surface to repair the electronic components in the first sealed cabin is also overcome. The ocean energy power generation device is directly overhauled underwater, so that the overhauling cost of the existing overhauling method is greatly reduced, the overhauling efficiency is improved, and the ocean energy power generation device can be really applied in a commercialized mode. And the maintainers are all overhauled inside the device, so that the overhauling operation is convenient, and the safety is high.
Although the present invention has been described with reference to the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of other modifications and variations without departing from the spirit and scope of the invention as defined by the appended claims.
