Description

Technical Field

[0001] The present invention relates to the technical field of floating breakwaters, and particularly to a floating breakwater for protecting deep - sea cages. Background Technique

[0002] A deep - sea cage is a kind of offshore aquaculture facility, and its release environment requires a relatively stable water area environment. Laying a breakwater around the deep - sea cage can defend against the invasion of waves, forming a hydraulic structure required for a sheltered water area, providing a stable and safe operation water area, and protecting the aquaculture environment from being damaged by huge waves.

[0003] Existing floating breakwaters are mostly in the form of plates or combined tubes, which break the wave structure to achieve the wave - proof purpose. There are also those that use ocean energy to consume wave energy to achieve wave - proofing. However, the layout range of the breakwater is usually very wide, and this design has problems such as complex structure, high production cost, and high maintenance cost, and is not suitable for large - scale promotion. Therefore, we have proposed a floating breakwater for protecting deep - sea cages. Summary of the Invention

[0004] The object of the present invention is to provide a floating breakwater for protecting deep - sea cages, which solves the problems raised in the background technique.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A floating breakwater for protecting deep - sea cages, including a connection frame, floating tubes, upper wave - dissipating tubes, and lower wave - dissipating tubes. A number of the connection frames are placed parallel to each other and are penetrated and connected by two front - and - rear floating tubes. The upper sides of the connection frames are connected by upper wave - dissipating tubes, and the lower sides of the connection frames are connected by lower wave - dissipating tubes. A wave - proof mechanism is arranged in the middle of the connection frame and between the two floating tubes.

[0006] The wave - proof mechanism includes a mounting plate, impact tubes, floating components, and wave - shielding components. The mounting plate is installed in the middle of the connection frame and between the two floating tubes. The impact tubes are installed on the mounting plate, and the inlets of the impact tubes point in the wave direction to receive waves. A number of floating components are arranged on the mounting plate at equal intervals. The floating components are powered to float by the impact tubes guiding the water flow. The wave - shielding components are arranged on the mounting plate and between adjacent floating components, and are driven by the floating components to float and unfold to block waves and consume their energy.

[0007] A number of partition plates are fixedly connected to the inner wall of the impact tubes to partition the water flow of the waves; The floating component includes a riser pipe, a floating rod, a floating ring, elastic ribs, a strip-shaped notch and a wave-breaking rod. The riser pipe is fixedly installed in a hole on the mounting plate and penetrates through the impact pipe. The floating rod is inside the riser pipe. The floating ring is fixedly connected to the floating rod. After the water flow of the wave impacts into the riser pipe, the floating rod can move upward under the buoyancy of the floating ring. The wave-blocking component is connected to the floating rod and can be driven by the floating rod to move upward and unfold. The bottom end of the floating rod is connected to the bottom end of the riser pipe through an elastic rib. A strip-shaped notch is formed on the side wall of the riser pipe. A plurality of wave-breaking rods are fixedly connected to the elastic rib from top to bottom, and the wave-breaking rods are located in the strip-shaped notch. When the floating rod moves upward, the elastic rib is stretched to expand the gap between adjacent wave-breaking rods, and the water flow is disturbed by the wave-breaking rods; The wave-blocking component includes a wave-blocking net. The wave-blocking net is arranged between adjacent floating rods, and the wave-blocking net can be unfolded when the floating rod moves upward.

[0008] Preferably, the cross-section of the impact pipe is in a trumpet shape, and its larger opening is the inlet, and the dividing plate is located at the outlet of the impact pipe.

[0009] Preferably, the floating component further includes a water inlet and a sealing ring. A water inlet is formed on the side wall of the riser pipe and is communicated with the inside of the impact pipe, and the water inlet points to the inlet direction of the impact pipe. A sealing ring is fixedly installed on the inner wall of the riser pipe and below the water inlet. The floating rod is movably connected in the sealing ring through a linear bearing. The floating ring is located above the water inlet, and the water flow of the wave can impact into the riser pipe through the water inlet.

[0010] Preferably, the wave-blocking component further includes a storage box and a box cover. The storage box is fixedly connected to the upper surface of the impact pipe and is located between adjacent riser pipes. The box cover is at the upper opening of the storage box. The bottom end of the wave-blocking net is fixedly connected to the bottom wall of the storage box, and the other end of the wave-blocking net is fixedly connected to the lower surface of the box cover. The top end of the floating rod is fixedly connected to the box cover through a connecting rod. When the floating rod moves upward, it drives the box cover to move upward and unfold the wave-blocking net.

[0011] Preferably, a partition plate is fixedly connected inside the upper wave-dissipating pipe to divide the upper wave-dissipating pipe into upper and lower parts. The top of the upper wave-dissipating pipe is communicated with the inside of the riser pipe through a communicating pipe. A plurality of drainage holes are formed on the partition plate. A plurality of telescopic pipes are fixedly communicated with the lower surface of the partition plate corresponding to the positions of the drainage holes. The bottom ends of the telescopic pipes are fixedly communicated with a drainage pipe. The drainage pipe is inserted into a socket at the bottom of the upper wave-dissipating pipe, and the socket is opposite to the drainage holes. The bottom end of the drainage pipe is closed, and a drainage opening is formed on the side wall of the drainage pipe.

[0012] Preferably, a shielding ring is fixedly connected to the upper wave-dissipating pipe, and the drainage pipe is inserted into the shielding ring.

[0013] By adopting the foregoing technical solutions, the beneficial effects of the present invention are: 1. The floating breakwater for deep-water cage protection utilizes the design of a wave-breaking mechanism, which can utilize floating components to transfer and consume wave internal energy, and at the same time, link wave-shielding components to shield and divide the raised waves, thereby destroying the wave shape to achieve the purpose of wave protection. The structure is simple and easy to maintain, which solves the problems raised in the background technology.

[0014] 2. The floating breakwater for deep-water cage protection uses an impact pipe to divert and destroy waves. A part of it is split and released by the dividing plate, and a part of it works toward the floating rod, converting kinetic energy into gravitational potential energy. At the same time, the design of the spillway pipe is used to release and divert the direction of the water flow, pushing the spillway to extend out of the upper wave-breaking pipe to spray water to form a water curtain to buffer the impact of waves, and the extension of the elastic tendons is used to deploy the wave-breaking rod to destroy the wave impact under the water surface.

DETAILED DESCRIPTION

[0017] See also Figures 1-8, the present invention provides a technical solution: a floating breakwater for deep - water cage protection, including a connection frame 1, floating pipes 2, upper wave - dissipating pipes 3 and lower wave - dissipating pipes 4. A number of connection frames 1 are placed parallel to each other and are penetrated and connected by two floating pipes 2 in the front and back. The breakwater should also be equipped with an anchoring assembly for fixing the position of the breakwater on the water surface. Please refer to Figure 1 , an anchoring assembly is arranged on the connection frame 1, mainly including an anchor rope and a counterweight. As a well - known technology, it is not marked in this application and is only shown without further elaboration. The upper sides of each connection frame 1 are connected by upper wave - dissipating pipes 3, and the lower sides of each connection frame 1 are connected by lower wave - dissipating pipes 4. A wave - preventing mechanism 5 is arranged in the middle of the connection frame 1 and between the two floating pipes 2.

[0018] In the attached drawings of this specification, only the structural form of a single connection frame 1 is shown. This breakwater should be a continuous structure formed by multiple connection frames 1 arranged in parallel in cooperation with floating pipes 2, upper wave - dissipating pipes 3 and lower wave - dissipating pipes 4. The floating pipe 2 is in a sealed hollow structure, providing buoyancy and floating on the water surface. The lower wave - dissipating pipe 4 stabilizes the center of gravity, and the anchoring assembly on the connection frame 1 is used for position anchoring.

[0019] Please refer to Figures 1-3 , FIGS. 5 - 8, the wave - preventing mechanism 5 includes a mounting plate 51, an impact pipe 52, a floating assembly 53 and a wave - shielding assembly 54. The mounting plate 51 is installed in the middle of the connection frame 1 and between the two floating pipes 2. The impact pipe 52 is installed on the mounting plate 51, and the inlet of the impact pipe 52 points to the wave direction for receiving waves. A number of floating assemblies 53 are arranged equidistantly on the mounting plate 51. The floating assembly 53 is powered to float by the impact pipe 52 guiding water flow. The wave - shielding assembly 54 is arranged on the mounting plate 51 and between adjacent floating assemblies 53, and is driven by the floating of the floating assembly 53 to unfold and block the waves to consume their energy.

[0020] Please refer to Figure 1 、 7 , the cross - section of the impact pipe 52 is in a trumpet shape, and its larger opening is the inlet. A number of partition plates 6 are fixedly connected to the inner wall of the impact pipe 52 near its outlet for dividing the water flow of the waves.

[0021] Please refer to Figures 1-3, 5 - 8, the floating component 53 includes a riser pipe 531, a water inlet 532, a sealing ring 533, a floating rod 534 and a floating ring 535. The riser pipe 531 is fixedly installed in the hole on the mounting plate 51 and penetrates through the impact pipe 52. A water inlet 532 is provided on the side wall of the riser pipe 531 and is communicated with the inside of the impact pipe 52, and the water inlet 532 points to the inlet direction of the impact pipe 52. A sealing ring 533 is fixedly installed on the inner wall of the riser pipe 531 and below the water inlet 532. The floating rod 534 is movably connected in the sealing ring 533 through a linear bearing. The floating ring 535 is fixedly connected to the floating rod 534 and is above the water inlet 532. When the flowing water of the wave impacts into the riser pipe 531 through the water inlet 532, the floating rod 534 can move upward under the buoyancy of the floating ring 535, and the wave - blocking component 54 connected to the floating rod 534 can be driven by the floating rod 534 to move upward and unfold.

[0022] Please refer to Figures 6-8 , the floating component 53 further includes elastic ribs 536, strip - shaped notches 537 and wave - breaking rods 538. The bottom end of the floating rod 534 is connected to the bottom end of the riser pipe 531 through the elastic ribs 536. A strip - shaped notch 537 is provided on the side wall of the riser pipe 531. A number of wave - breaking rods 538 are fixedly connected to the elastic ribs 536 from top to bottom, and the wave - breaking rods 538 are located in the strip - shaped notch 537. When the floating rod 534 moves upward, the elastic ribs 536 are stretched, which can expand the gap between adjacent wave - breaking rods 538 to disrupt the water flow by using the wave - breaking rods 538.

[0023] Please refer to Figures 1-2 , the wave - blocking component 54 includes a storage box 541, a box cover 542 and a wave - blocking net 543. The storage box 541 is fixedly connected to the upper surface of the impact pipe 52 and is between adjacent riser pipes 531. The box cover 542 is at the upper opening of the storage box 541. The bottom end of the wave - blocking net 543 is fixedly connected to the bottom wall of the storage box 541, and the other end of the wave - blocking net 543 is fixedly connected to the lower surface of the box cover 542. The top end of the floating rod 534 is fixedly connected to the box cover 542 through a connecting rod 15. When the floating rod 534 moves upward, it drives the box cover 542 to move upward and unfold the wave - blocking net 543.

[0024] Please refer to Figures 3-4, a partition plate 7 is fixedly connected inside the upper wave dissipating pipe 3 to divide the upper wave dissipating pipe 3 into upper and lower parts. The top of the upper wave dissipating pipe 3 is in communication with the inside of the vertical pipe 531 through a connecting pipe 8. A number of drainage holes 9 are formed in the partition plate 7, and a number of telescopic pipes 10 are fixedly connected to the lower surface of the partition plate 7 corresponding to the positions of the drainage holes 9. The bottom ends of the telescopic pipes 10 are fixedly connected with drainage pipes 11. The drainage pipes 11 are inserted into the sockets 12 at the bottom of the upper wave dissipating pipe 3, and the sockets 12 are opposite to the drainage holes 9. The bottom ends of the drainage pipes 11 are closed, and drain openings 13 are formed in the side walls of the drainage pipes 11. A shielding ring 14 is fixedly connected to the upper wave dissipating pipe 3, and the drainage pipes 11 are inserted into the shielding ring 14. The shielding ring 14 is used to cover the drain openings 13 on the drainage pipes 11. After the water flow enters the drainage pipes 11 through the telescopic pipes 10, it will first impact the drainage pipes 11 to make them extend out of the upper wave dissipating pipe 3, so that the drain openings 13 are also outside the upper wave dissipating pipe 3, and the ejected water flow forms a water curtain, which cooperates with the drainage pipes 11 to destroy the wave form and achieve the wave prevention purpose.

[0025] The partition plate 6 divides the water flow, the floating rod 534 moves upward to stretch the elastic tendon 536, the wave shielding net 543 unfolds to block the waves, and the drainage pipe 11 extends out to destroy the waves. These wave prevention methods progress layer by layer. When the wave intensity is small, only the floating rod 534 can be driven to move slightly upward. Most of the waves are divided and destroyed by the partition plate 6, and the wave shielding net 543 is partially unfolded. The pressure of the water flow is not enough to support it to enter the upper wave dissipating pipe 3 through the connecting pipe 8. As the waves increase, the stretching amplitude of the wave shielding net 543 will also increase. Finally, the water flow rushes into the upper wave dissipating pipe 3 to form a multiple wave prevention state.

[0026] When the device works, this breakwater floats on the water surface by the buoyancy of the floating pipe 2 and is moored by the mooring assembly. The waves rush towards the large opening of the impact pipe 52, and part of the water flow is discharged after being divided by the partition plate 6 to reduce the impact. The other part rushes into the vertical pipe 531. The floating ring 535 touches the water and floats, so that the water flow enters the upper side of the vertical pipe 531. The greater the wave impact, the higher the floating ring 535 rises. The floating ring 535 drives the floating rod 534 to rise and stretch the elastic tendon 536, so that the wave breaking rod 538 follows the movement to form a turbulent flow and destroy the underwater undercurrent brought by the waves. And the elastic potential energy of the elastic tendon 536 comes from the conversion of wave kinetic energy, and it can also drive the floating ring 535 to reset during the wave impact gap. And the rising of the floating rod 534 also drives the wave shielding net 543 to rise. The waves on the upper side of the impact pipe 52 can be blocked and destroyed by the wave shielding net 543. And the water flow entering the vertical pipe 531 will also enter the upper wave dissipating pipe 3 to use the water pressure to push out the drainage pipe 11 to destroy the waves.

[0027] Various modifications to these embodiments will be apparent to those of ordinary skill in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
