[0043] The technical features of the present invention are further described below in conjunction with 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 to carry materials 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 the water and can float in the 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 in a plate shape.

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

[0047] In this embodiment, the connecting member includes a first component and a second component that can be engaged. The first component and the second component are respectively arranged at opposite ends of two adjacent floating plate units 1. Among them, the first component of one floating plate unit 1 and the second component of the other floating plate unit 1 of the two adjacent floating plate units 1 are engaged together to achieve the connection of the two floating plate units 1. Among them, the connecting member is a hinged member, which allows the floating plate to move to a certain extent on the basis of achieving a stable connection of the structure to adapt to different working conditions.

[0048] A plurality of turbine generators 302 are arranged in the floating bridge body, and turbine generators 302 are arranged 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 type OWC power generation device also includes an oscillating water column type 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 type power generation device and the inflation of the airbag 2.

[0050] The deck of the floating bridge of the present application is strong and can pass 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 laying requirements of rivers or oceans of different lengths, and is convenient for construction.

[0051] In this embodiment, the floating board unit 1 of the floating bridge body adopts an inflatable floating board. When installing the floating bridge body, it only needs to be placed on the water surface, and the floating bridge will be automatically inflated slowly, and then it can be put into use after the inflation is completed. When responding to weather disasters, the floating bridge can be quickly inflated and put into use, and a certain section of the bridge component can be used alone as a floating board, and connected to a motorboat to rescue people trapped in the flood.

[0052] The oscillating water column type power generation device 3 comprises an air chamber 301 and a turbine generator 302. The air chamber 301 is columnar, and both ends of the air chamber 301 have openings and the two 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 opening 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 the present application generates electricity. In the river, vehicles walking on the bridge deck will cause the bridge deck to float up and down, thereby causing 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 wave crests and troughs advance alternately, causing the water in the air chamber 301 to oscillate up and down, compressing and expanding the gas in the air chamber, thereby generating reciprocating airflow to push the air so that the turbine generator 302 works and generates electricity, realizing functions such as lighting and reducing turbulence.

[0056] At least some of the floating plate units 1 are connected to the airbag 2. In actual use, the airbag 2 can be connected to one of two adjacent floating plate units 1 or all of the airbags 2 can be connected to the lower parts of two adjacent floating plate units 1. An airbag connecting member is provided between the airbag 2 and the floating plate unit 1, and the airbag 2 and the floating plate unit 1 are connected by the airbag connecting member.

[0057] The airbag connecting component includes a slide rail 4 and a sliding member 5, and the sliding member 5 is slidably inserted in the slide rail 4. The top of the sliding member 5 is provided with 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 sliding member 5, and the other end of the damper 7 is fixed to the lower surface of the floating 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 are in contact with the sliding member 5 and the lower surface of the floating bridge body respectively.

[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. 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] There is a gas communication channel between the power input end of the turbine generator 302 and the air inlet of the airbag 2, and a closable valve device is provided in the middle section of the gas communication channel. In this embodiment, a through hole connected to the air inlet of the turbine generator 302 can be provided at the lower part of the floating plate unit 1, and then a through hole penetrating the sliding member 5 is constructed inside the sliding member 5, and a second through hole penetrating the sliding rail 4 is constructed in the groove of the sliding rail 4, and the air inlet of the airbag 2 can cooperate with the second through hole. After the installation is completed, the through hole at the lower part of the floating plate unit 1, the through hole of the sliding member 5, the second through hole of the sliding 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; utilize the reciprocating airflow of the oscillating water column 301 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 hole, close the power generation device, and the gas of the oscillating water column power generation device all 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 hole. 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 coming out, 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. The lighting devices are arranged on both sides of the bridge deck of the floating bridge body and are electrically connected to the power output end of the turbine generator 302. The turbine generator 302 provides power for the lighting devices. Fences can be added on both sides of the bridge deck, and light bulbs are installed on the fences as lighting devices.

[0065] The end of the air chamber 301 connected to the power input end of the turbine generator 302 has 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 fabrics spliced ​​into a closed container with an air inlet. The high-strength PVC coated fabric is wear-resistant and corrosion-resistant, has strong UV resistance, is light in weight and high in strength, and can meet the strength and reliability requirements of long-term work at sea.

[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 protection scope of the present invention.
