Description

Technical Field

[0001] This disclosure relates to the field of fluid power technology, and specifically to an underwater power system. Background Technology

[0002] The Earth possesses abundant hydropower resources, with oceans covering approximately 71% of the surface. Seawater in different regions, influenced by factors such as wind and temperature differences, forms stable ocean currents that move regularly in certain directions, with flow speeds ranging from 0.5 to 2 meters per second. In some strong current areas, such as the Gulf Stream and the Kuroshio Current, these speeds can reach 3 to 4 meters per second. Furthermore, numerous large rivers flow continuously throughout the world, with flow speeds reaching 2 to 3 meters per second or even higher. These flowing water bodies contain enormous amounts of green energy, and utilizing this energy for work or electricity generation can bring significant benefits to human society.

[0003] Most existing methods of using water flow to generate electricity involve intercepting the water flow and then using the potential energy generated by the height difference to drive a turbine to rotate. These devices are commonly found in dams or tidal power stations. Another type involves fixing a turbine generator below the water flow, using the water flow to drive the turbine mounted on the generator to rotate, and then the turbine drives the generator to produce electricity.

[0004] However, most dams are built in mountainous areas where rivers flow through significant elevation differences. This not only results in long construction periods and huge investments, but also causes significant, even catastrophic, impacts on the surrounding ecosystem and climate. Tidal power stations, a low-head, high-flow-rate power generation method, also suffer from complex construction, huge investments, and low annual utilization hours. Stationary turbines, limited by their size and structural characteristics, often have lower power output and poor adaptability to changes in water flow. Utility Model Content

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and beneficial effects of the embodiments in the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely in the following with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present disclosure.

[0042] Embodiment 1

[0043] This embodiment provides an underwater power generation system. The system is directly installed underwater and uses the kinetic energy of water to perform work or generate electricity. It does not produce greenhouse gas emissions or noise pollution, making it environmentally friendly. Furthermore, it can utilize the natural topography of the water body to perform work and generate electricity without the need for damming or other large-scale infrastructure construction. It has fewer environmental restrictions and high efficiency in utilizing the kinetic energy of water.

[0044] like Figure 1 As shown, the underwater power generation system in this embodiment includes a power generation module located underwater and a working platform 100 for controlling it. The working platform 100 can be a floating island or a platform supported by a tower that is fixed to the water by anchor chains. It is used to carry the power generation or power generation equipment and the necessary control equipment 101. The working platform 100 also includes necessary cable guide pulleys 102 for smoothly connecting equipment outside the platform.

[0045] The working module includes a guide mechanism 200 extending underwater for a certain distance. The guide mechanism 200 can be a wear-resistant and corrosion-resistant rope or a metal slide rail. The guide mechanism 200 is configured to autonomously adjust its direction according to the water flow direction and maintain a suitable working angle, thereby obtaining the maximum water kinetic energy. One end of the guide mechanism 200 is connected to the working platform 100, and the other end is connected to the balancing module. The balancing module includes a balancing umbrella 203 with a central opening and a counterweight 204.

[0046] The central opening of the balancing umbrella 203 not only keeps the umbrella stable but also allows fish or other debris in the water to pass through smoothly without damaging the umbrella. Under the action of the water flow, the balancing umbrella 203 is in the normally open state and provides a pulling force F1 biased towards the water flow direction. The counterweight 204 provides a pulling force F2 that is roughly along the direction of gravity and slightly biased towards the water flow direction. The resultant force of F1 and F2 pulls the guide mechanism 200 at a certain angle towards the bottom of the water flow.

[0047] A working umbrella is mounted on the guide mechanism 200, or several working umbrellas 500 are connected in series at certain intervals. The working umbrellas 500 can be circular flat umbrellas or symmetrical polygonal configurations. The guide mechanism 200 passes through the opening at the top of the working umbrella 500, and the working umbrella is connected to the working rope 300.

[0048] One end of the work rope 300 is connected to the work-generating or power-generating equipment installed on the work platform 100, and is controlled by the work platform 100 to reciprocate along the guide mechanism 200. It is pulled by the work umbrella 500 using water flow power to perform work or generate electricity. The work platform controls the retrieval of the work rope. A single work umbrella or a ladder formation of several work umbrellas captures the kinetic energy of the water flow, thereby generating a huge tensile force on the umbrella rope. This tensile force is transmitted to the work platform through the work rope, driving the mechanical equipment on the platform to perform work or generate electricity.

[0049] The work module further comprises a work rope limiting mechanism for limiting the work rope 300 so that it does not disengage from the guide mechanism 200 when doing reciprocating motion. In the preferred embodiment, a first limiting mechanism 502 corresponding to each work umbrella 500 is arranged below the umbrella perimeter of the work umbrella 500.

[0050] Reference Figure 2 In the exemplary embodiment, the center of the first limiting mechanism 502 is provided with a first channel 5021, and the guide mechanism 200 passes through the first channel 5021 so that the first limiting mechanism 502 can slide reciprocally along the guide mechanism 200 under force. A second channel 5022 is arranged around the outside of the first channel 5021, the second channel 5022 is connected in series on the work rope 300, and the distal end and the proximal end of the second channel 5022 are respectively provided with limiting clamps for limiting the work rope. A plurality of first tether accessories 5023 are arranged around the outside of the second channel 5022, and the umbrella perimeter of the work umbrella 500 is uniformly connected to a plurality of first umbrella ropes 501, and the ends of the first umbrella ropes 501 are respectively connected to the first tether accessories 5023.

[0051] In a more preferred embodiment, the first tether accessories 5023 are arranged on a first rotating mechanism 5024, and the first rotating mechanism 5024 can freely rotate around the first limiting mechanism 502 (also around the guide mechanism 200). When the work umbrellas 500 are opened, all the work umbrellas 500 capture the kinetic energy of the water flow and pull the work rope 300 together, and the work rope 300 drives the equipment on the working platform to do work or drives the generator to generate electricity. The second channel connected in series with the work rope 300 is non-rotating, avoiding entanglement of the work rope 300 with the first umbrella rope 501.

[0052] In the preferred embodiment, the center of the umbrella top opening of each work umbrella 500 is also provided with a second limiting mechanism 503 corresponding thereto, and the arrangement of the second limiting mechanism 503 can be referred to the first limiting mechanism 502. The center of the second limiting mechanism 503 is provided with a third channel 5031, and the guide mechanism 200 passes through the third channel 5031 so that the second limiting mechanism 503 can slide reciprocally along the guide mechanism 200 under force. A fourth channel 5032 is arranged around the outside of the third channel 5031, the fourth channel 5032 is connected in series with the control rope 400, and the distal end and the proximal end of the fourth channel 5032 are respectively provided with limiting clamps for limiting the control rope, and one end of the control rope 400 is connected to the rope container winch of the working platform 100, and the working platform 100 controls the winding and unwinding of the control rope 400.

[0053] A plurality of second tie accessories 5033 are arranged around the outer side of the fourth channel 5032. The umbrella top opening edges of the working umbrella 500 are uniformly connected to a plurality of second umbrella ropes, and the ends of the second umbrella ropes are respectively connected to the second tie accessories 5033. The appropriately sized openings at the top of the working umbrella 500 can also be used to maintain the stability of the umbrella body, while allowing fish or debris to pass through smoothly, avoiding damage to the umbrella body.

[0054] The second tie accessories 5033 are arranged on the second rotating mechanism 5034, which can freely rotate about the second limiting mechanism 503 (and also freely rotate about the guide mechanism 200). The fourth channel of the series-connected control rope 400 is non-rotating, avoiding entanglement with the second umbrella ropes.

[0055] In this embodiment, when the working umbrella 500 is opened to work, the control rope 400 is continuously in a rope releasing state. Since a certain pulling force can also be provided at the umbrella top to act on the control rope 400 through the second umbrella ropes and the second limiting mechanism 503, the rope releasing stage does not require or only requires a small amount of energy to be consumed by the winch to achieve smooth rope releasing.

[0056] In the preferred scheme, the guide mechanism 200 is provided with an initial stopper 201 near one end of the working platform 100 and an end stopper 202 at the other end. The first limiting mechanism 502 and the second limiting mechanism 503 are limited to slide between the initial stopper 201 and the end stopper 202.

[0057] The working system of this embodiment uses water flow power to drive the working umbrella to automatically open and close, which not only has high efficiency and stable working state, but also does not require additional energy consumption. Moreover, water has high density and stable flow rate, and its energy density is about 800 times or more than that of wind at the same flow rate. By cascading a plurality of working umbrella groups, a considerable amount of water flow kinetic energy can be captured, and the output power can be much higher than that of ordinary ocean current turbine generators.

[0058] Compared with other similar umbrella-type working systems, such as high-altitude wind energy working systems, the underwater working system in this embodiment does not require the use of long working ropes, and the complex walking drive is also omitted, greatly simplifying the balance system and other modules. Not only does this significantly reduce the system cost, but it also makes operation more convenient, safe and reliable.

[0059] Embodiment 2

[0060] This embodiment provides an underwater working method, which is performed in the underwater working system in Embodiment 1.

[0061] Reference Figures 3-5 The method of this embodiment is performed according to the following steps:

[0062] a. Reference Figure 1When the working umbrella 500 closest to the working platform 100 is retracted by the winch mechanism to the initial stopper 201 of the guide mechanism 200, the working rope is locked, the control rope 400 is released, and the control rope is in a releasing state. Under the impact of the water flow, the second limiting mechanism 503 at the top of each working umbrella 500 will slide forward along the guide mechanism 200, and the shape of the working umbrella 500 will change, so that the working umbrella 500 quickly ends the overturning state and recovers to Figure 1 the opening state shown and captures the kinetic energy of the water flow;

[0063] b. Unlocking the working umbrella, at this time, the working umbrella 500 moves along the guide mechanism 200 under the action of the water flow, thereby driving the working umbrella 500 to drive the working or power generation equipment to work or generate power;

[0064] c. Referring to Figure 3 When the working umbrella 500 at the end of the working rope 300 moves to the end stopper 202 of the guide mechanism 200, the second limiting mechanism 503 at the top of the working umbrella 500 is limited at this position, and at this time, the working platform's rope-containing winch immediately locks the control rope 400 and stops releasing the control rope 400 (the working platform 100's rope-containing winch can also adjust the upper limit of the working stroke through the releasing length and confirm the control rope 400 in time). Thus, the second limiting mechanism 503 of all working umbrellas connected in series on the control rope stops moving on the guide mechanism 200. Under the impact of the water flow, each working umbrella 500 will overturn forward and continue to drive the first limiting mechanism 502 and the working rope 300 forward for a certain distance through the first umbrella rope 501, and then quickly lose power and no longer move forward;

[0065] d. Referring to Figure 4 When the working umbrella 500 loses power and no longer moves forward, the control device 101 controls the synchronous recovery of the working rope 300 and the control rope 400, which can quickly pull all the working umbrellas 500 back to the initial stopper 201 near the end with only a small amount of energy consumption;

[0066] e. Repeat steps a to d.

[0067] In the preferred scheme, referring to Figure 5 When performing step d, when the first limiting mechanism 502 of the working umbrella 500 closest to the working platform 100 approaches the initial stopper 201 of the guide mechanism 200, the recovery of the control rope 400 can be stopped but the recovery of the working rope 300 can be continued, at this time, each working umbrella 500 will quickly end the overturning state and convert to the open umbrella working state, which is easier to achieve than relying solely on the release of the control rope 400.

[0068] The embodiment utilizes water flow energy, through cooperation of work ropes and control ropes, utilizes underwater umbrella ladder group to drive work or power generation equipment to work or generate power, and realizes efficient and stable energy conversion.

[0069] The above-mentioned embodiments and application examples are only exemplary descriptions of the present disclosure, and do not limit the scope of the present disclosure. Without departing from the design spirit of the present disclosure, various modifications and improvements of the technical solutions of the present disclosure made by those skilled in the art shall fall within the protection scope of the present disclosure.
