Description

Technical Field

[0001] The utility model relates to a floating bridge type OWC power generation device, belonging to the field of floating bridge equipment. Background Art

[0002] Currently, floating bridges are bridges supported on the water surface by buoyancy, primarily used for short-term or emergency purposes. Floating bridges have the advantages of rapid construction, temporary design, and high adjustability, making them widely used in warfare, disaster relief, and other areas. The following are several existing floating bridge technology solutions:

[0003] Catenary floating bridges: These bridges consist of steel cables and wooden decks suspended above the water. Their advantages are rapid construction and the ability to support vehicle traffic. However, their disadvantages include a low load-bearing capacity and poor suitability for long spans across water.

[0004] Floating pontoon bridges consist of bulk pontoons, decking, and connectors. The pontoons are filled with gas or foam, allowing the decking to float on the water. Advantages include ease of construction, adaptability to long spans and high-flow rivers, and wide applicability. Disadvantages include high design, processing, and assembly requirements, resulting in higher costs and unsuitability for use in tidal and rough waters.

[0005] The main disadvantages of existing floating bridges include:

[0006] Poor stability: At sea, affected by wind and waves, the pontoon is prone to shaking, affecting its use and safety.

[0007] Poor durability: Seawater corrosion and severe weather conditions can cause damage to the components of the pontoon, requiring frequent repairs and replacements.

[0008] Low energy efficiency: Traditional floating bridges can only be used as a means of transportation or venue, and are unable to utilize natural resources such as waves and tides for energy.

[0009] With the development of floating bridge technology, more and more floating bridges are appearing. However, few are using marine energy for power generation or stability enhancement. Existing floating bridge power generation systems all utilize built-in turbines to generate hydropower. However, these systems suffer from shortcomings such as low head, high flow velocity requirements, low power generation efficiency, and high construction costs. Furthermore, their application is limited to inland rivers. In the ocean, seawater can severely corrode turbine blades. Utility Model Content

[0043] The technical features of the present invention are further described below with reference to the accompanying drawings and specific embodiments.

[0044] As shown in the figure, the present invention discloses a floating bridge type OWC power generation device, which can provide a floating board for transporting supplies and lighting in the absence of a generator in disaster relief and other situations. The present application includes a floating bridge body, which has buoyancy in water and can float in water.

[0045] In the present application, the floating bridge body includes a plurality of floating plate units 1, and the floating plate units 1 are plate-shaped.

[0046] All the floating plate units 1 are connected in sequence, and there is a connector between two adjacent floating plate units 1. The two adjacent floating plate units 1 are connected through the connector.

[0047] In this embodiment, the connector includes a first and second engaging components. The first and second components are disposed at opposite ends of two adjacent floating plate units 1. The first component of one floating plate unit 1 and the second component of the other floating plate unit 1 engage together to connect the two floating plate units 1. The connector is a hinged joint that allows for a certain amount of movement of the floating plates to adapt to varying operating conditions while maintaining a stable connection.

[0048] A plurality of turbine generators 302 are provided in the floating bridge body. Turbine generators 302 are provided in at least some of the floating plate units 1. Each turbine generator 302 is connected to at least two air chambers 301.

[0049] The floating bridge OWC power generation device also includes an oscillating water column power generation device 3. The floating bridge body of the present application has a certain buoyancy when thrown into the water to ensure the floating state, and then obtains more buoyancy through the oscillating water column power generation device and the inflation of the air bag 2.

[0050] The deck of the floating bridge of the present application is strong and can accommodate vehicles and pedestrians. The deck of the floating bridge is connected by various floating plate units 1 through connectors, which ensures the stability of the floating bridge connection and can adapt to the paving requirements of rivers or oceans of different lengths, making construction convenient.

[0051] In this embodiment, the floating bridge's pontoon unit 1 is an inflatable float. To install the bridge, simply place it on the water surface, where it will automatically inflate and be ready for use. To respond to weather disasters, the bridge can be quickly inflated and deployed, with individual sections of the bridge used as floats, connected to motorboats, to rescue people trapped in floodwaters.

[0052] The oscillating water column power generation device 3 comprises an air chamber 301 and a turbine generator 302. The air chamber 301 is columnar, with openings at both ends thereof, and the openings at both ends of the air chamber 301 are connected. In this embodiment, the turbine generator 302 is an impulse turbine.

[0053] In this embodiment, the turbine generator 302 is arranged inside the floating plate unit 1 to realize the power generation function, and batteries are installed inside the floating bridge body to store electrical energy.

[0054] The air chamber 301 is a cylindrical air chamber. One of the openings of the air chamber 301 is connected to the power input end of the turbine generator 302, and the other opening of the air chamber 301 is located below the floating bridge body.

[0055] The oscillating water column wave energy power generation floating bridge of this application generates electricity. When traveling on a river, vehicles on the bridge deck cause the bridge deck to rise and fall, which in turn causes the water in the air chamber 301 to oscillate up and down, compressing and expanding the gas in the air chamber 301. On the sea surface, the alternating crests and troughs of the waves cause the water in the air chamber 301 to oscillate up and down, compressing and expanding the gas in the air chamber 301. This in turn generates a reciprocating airflow that propels the air, causing the turbine generator 302 to operate and generate electricity, thus achieving functions such as lighting and reducing turbulence.

[0056] At least some of the float units 1 are connected to airbags 2. In actual use, an airbag 2 can be connected to one of two adjacent float units 1, or to the lower portions of both adjacent float units 1. Airbag connecting members are provided between the airbags 2 and the float units 1, connecting the airbags 2 and the float units 1 via the airbag connecting members.

[0057] The airbag connecting member includes a slide rail 4 and a slider 5, which is slidably inserted into the slide rail 4. The top of the slider 5 has a buffer device. In this embodiment, the buffer device adopts a damping anti-impact mechanism. The buffer device includes a damper 7 and a spring 6. One end of the damper 7 is fixed to the top of the slider 5, and the other end of the damper 7 is fixed to the lower surface of the pontoon bridge body. In this embodiment, the damper 7 adopts a piston sleeve damping device. The spring 6 is sleeved on the damper 7, and the two ends of the spring 6 respectively contact the slider 5 and the lower surface of the pontoon bridge body.

[0058] In this embodiment, the airbag 2 is an inflatable structure, the turbine generator 302 is arranged inside the bridge deck 3, the air chamber 301 is connected to the turbine generator, and the electricity can be stored in the battery 12. When electricity is used, it is discharged through the battery 12.

[0059] The airbag 2 provides additional buoyancy for the floating plate unit 1 and even the entire floating bridge body, and can be inflated manually and automatically. In addition, the airbag 2 and the floating plate unit 1 are connected by a slide rail, and different types of airbags can be replaced according to the carrying capacity to meet different transportation requirements.

[0060] A gas communication channel is established between the power input of the turbine generator 302 and the air inlet of the airbag 2, with a closable valve device in the middle of the gas communication channel. In this embodiment, a through hole is provided at the bottom of the floating plate unit 1 to connect to the air inlet of the turbine generator 302. A through hole is then formed within the slider 5, extending through the slider 5. A second through hole is then formed within the groove of the slide rail 4, extending through the slide rail 4. The air inlet of the airbag 2 can mate with the second through hole. After installation, the through hole at the bottom of the floating plate unit 1, the through hole of the slider 5, the second through hole of the slide rail 4, and the air inlet of the airbag 2 are connected to form a gas communication channel.

[0061] When generating electricity, close the valve at the airbag end and the one-way valve b9 of the bridge deck vent 8. At this time, the vent can both take in and exhaust air; the reciprocating airflow of the oscillating water column 301 is used to drive the impulse turbine to achieve power generation.

[0062] When inflating, open the valve 10 and the one-way valve a11 at the airbag end, open the one-way valve b9 of the bridge deck air inlet, close the power generation device, and the gas of the oscillating water column power generation device enters the airbag 2 through the gas connecting channel, and continuously absorbs the outside air into the airbag 2 through the bridge deck air inlet. Then, when the inflation is completed, close the one-way valve b9 in the bridge deck vent 8, and then the airflow in the air chamber 301 becomes a reciprocating airflow to drive the air turbine device to rotate and generate electricity.

[0063] The one-way valve a11 prevents the gas entering the airbag 2 from escaping, and the one-way valve b9 prevents the air in the bridge deck vent 8 from entering the pipe. The two valves work together to allow the oscillating water column device to inflate the airbag 2.

[0064] The present application may also include lighting devices. These lighting devices are installed on both sides of the bridge deck and are electrically connected to the power output of the turbine generator 302, which provides power for the lighting devices. Fences can be added on both sides of the bridge deck, with light bulbs installed on the fences as lighting devices.

[0065] The end portion where the air chamber 301 is connected to the power input end of the turbine generator 302 is provided with a breathable waterproof membrane. The breathable waterproof membrane can ensure that water will not surge into the air turbine generator through the air chamber and cause damage to the air turbine generator.

[0066] The airbag 2 is made of high-strength PVC-coated fabric, forming a closed container with an air inlet. High-strength PVC-coated fabric is wear-resistant, corrosion-resistant, and UV-resistant, while being lightweight and high-strength, meeting the strength and reliability requirements for long-term offshore operation.

[0067] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the scope of protection of the present invention.
