Description

Technical Field

[0001] The present invention belongs to the field of floating breakwaters, and particularly relates to an adjustable floating breakwater suitable for long waves. Background Art

[0002] Generally, the main body of a floating breakwater is composed of a box body with a certain draft depth and a floating raft. The box body and the floating raft are connected to an anchor chain fixed at one end of the seabed and thus float on the water surface. Its wave dissipation principle is to use the floating body to prevent the wave from propagating or to break the wave, and the movement of the floating body under the action of the wave interferes with the movement of the water particles in the wave, so as to achieve the purpose of wave dissipation and energy reduction.

[0003] The advantages of the existing floating breakwaters are mainly reflected in: having good water quality exchange ability, low cost, strong applicability, short construction period, convenient installation and disassembly, etc. Its disadvantages are that the ordinary configuration has limited wave dissipation effect on long-period waves, and the overall safety and reliability are lower than those of fixed breakwaters.

[0004] The applicant retrieved a Chinese invention patent with the publication number: CN113718708B and the name: A floating breakwater for offshore photovoltaic porous multi-stage attenuating wave energy, which discloses a fixed seat and an offshore photovoltaic support platform. Fixed plate assemblies are installed below both sides of the fixed seat, and a chain winding drum assembly is arranged inside the fixed seat. By the impact of sea waves on the one-way valve plug rod inside the circular through hole, and then driving the limit spring to move, the slow-flow function is achieved through the movement of the limit spring, and the water flow enters the interior of the offshore side wave storage tank cylinder through the circular through hole and is pushed out by the offshore wave pushing plate. When the undercurrent passes through the connecting chain, it contacts the downwelling wave interception net for buffering.

[0005] However, the above technical solution cannot effectively utilize wave energy, and at the same time, it cannot stabilize itself well. Summary of the Invention

[0017] Beneficial effects: Compared with the prior art, the remarkable technical effects of the present invention are as follows: (1) By providing a front floating box and a rear floating box, and respectively installing a front water injection tank and a rear water injection tank at their upper ends. At the same time, water pumps are installed on the right sides of the front water injection tank and the rear water injection tank. Connecting plates are connected between the front floating box, the rear floating box and the front water injection tank, the rear water injection tank, so that the front and rear can form an integral body. At the same time, water can be injected into the front water injection tank, the front floating box, the rear water injection tank and the rear floating box respectively through the water pumps to adjust and increase the weights on the front and rear sides, so as to increase the self-weight of the breakwater and improve stability. At the same time, the first electric hydraulic cylinder can drive the sliding rod to move up and down, so that the sliding rod slides in the guiding slide rail, and then drives the water guide plate to rotate up and down to adjust its inclination angle. When the wave scours the water guide plate, different impact forces can be generated, so as to effectively drive the small turbine generator set to operate and generate electricity, and store the generated electric energy in the battery pack. The electric energy stored in the battery pack can also be supplied to each control device, the first electric hydraulic cylinder, the second electric hydraulic cylinder and the water pump. At the same time, after the wave passes through the small turbine generator set, part of it can be discharged through the water guide groove and the drain port, and part of it is guided to rush upward to the water guide arc plate. Due to the arc-shaped setting of the water guide arc plate, an upward thrust can be generated on the water guide arc plate, further offsetting the pressure of the wave scouring the water guide plate and increasing the overall stability of the device; (2) At the same time, when the long-wave wave rushes onto the water guide plate, a downward pressure will be generated on the front floating box. At the same time, when the wave passes through the small turbine generator set, part of the residue will still rush onto the water guide arc plate. Due to the arc-shaped setting of the water guide arc plate, an upward thrust can also be generated on the front floating box to overcome the pressure, making the whole more stable. At the same time, when the thrust generated by the water guide arc plate and the wave is not enough, the second electric hydraulic cylinder can extend to push the second pin seat forward, and then drive the water guide arc plate to rotate more forward through the rotating plate, so as to generate enough thrust. During the process of the second pin seat moving forward, the L-shaped side plate will also pull the pull rope to drive the wire reel and the lead screw to rotate, and then drive the threaded sleeve and the rack sleeved on the lead screw to move to one side. Through the meshing connection between the rack and the gear, the rotating shaft and the diversion plate are driven to rotate, and the angle formed by the diversion plate and the oncoming flow is adjusted, so as to reduce the overall sway of the floating breakwater and improve stability; (3) The device is convenient to adjust, can effectively reduce long-period waves, use long waves for self-generation and use the self-generated electricity to control the components on the breakwater, and at the same time improve the stability of the floating breakwater itself.

[0045] At the same time, after the waves pass through the small turbine generator set 32, part of them can be discharged through the water guiding groove 31 and the drain port, and part of them are guided to wash upward against the water guiding arc plate 4. Due to the arc-shaped setting of the water guiding arc plate 4, an upward thrust can be generated on the water guiding arc plate 4, further offsetting the pressure of the waves washing onto the water guiding plate 3, and increasing the overall stability of the device.

[0046] Please refer to Figures 1-6The present invention provides a technical solution: the adjustable mechanism includes: an L-shaped side plate 81, a third pin shaft seat 82, a screw rod 85, a winding wheel 84, and a threaded sleeve 86. The left and right sides of the second pin shaft seat 74 are fixedly connected to the L-shaped side plate 81, and the rear end of each L-shaped side plate 81 is fixedly connected to a pull rope 83.

The gear 102 and the rack 103 fixedly connected to the upper end of the rotating shaft 101 are at the same height.

[0047] When the water guide arc plate 4 and the waves are not sufficient to generate sufficient thrust, the second electric hydraulic cylinder 71 can be extended to push the second pin shaft seat 74 forward, and then the water guide arc plate 4 can be driven to rotate further forward through the rotating plate 72, thereby generating sufficient thrust. During the forward movement of the second pin shaft seat 74, the pull rope 83 will be pulled through the L-shaped side plate 81 to drive the winding wheel 84 and the screw rod 85 to rotate, and then the threaded sleeve 86 threaded on the screw rod 85 and the rack 103 are driven to move to one side, and the meshing connection between the rack 103 and the gear 102 drives the rotating shaft 101 and the guide plate 5 to rotate, and the angle formed by the guide plate 5 and the incoming flow is adjusted, thereby reducing the overall shaking of the floating breakwater and improving stability.
