[0039] Please see Figures 1-4 The present invention will now describe a noise reduction and sound insulation device for marine construction provided by an embodiment of the present invention.

[0040] In one embodiment of this utility model, a noise reduction and sound insulation device for offshore construction includes: a pile stabilization platform, an annular rubber soundproof cover 3, a bubble tube 4, and an air compressor 5. The pile stabilization platform includes multiple columns 1 and multiple crossbeams 2 connected between adjacent columns 1. The annular rubber soundproof cover 3 is connected to one side of the pile stabilization platform through a first connecting component. The bubble tube 4 is connected to the lower side of the annular rubber soundproof cover 3 through a second connecting component, and the bubble tube 4 surrounds the outer periphery of the annular rubber soundproof cover 3. The bubble tube 4 is provided with multiple air outlets at intervals. The air compressor 5 is connected to the bubble tube 4 and is used to fill the bubble tube 4 with compressed air.

[0041] In this embodiment, the pile stabilization platform includes four symmetrically arranged columns 1 at the four corners, with multiple crossbeams 2 connecting adjacent columns 1 from bottom to top. The bubble tube 4 is a 100 mm diameter HDPE pipe, connected to an air compressor 5 on the bubble curtain construction vessel via a non-perforated air supply pipe. The air compressor 5 can provide air with a pressure of not less than 1.0 MPa, a flow rate of 20 m³ / min, and a pressure rating of 1.6 MPa. The air outlet holes on the bubble tube 4 have a diameter of 3 mm and a spacing of 0.3–0.4 m. Before the hammer-driven pile driving operation, the air compressor 5 is started to form a cylindrical bubble curtain in the seawater surrounding the annular rubber soundproof cover 3 to reduce pile driving noise propagating outward through this interface.

[0042] In this embodiment, the diameter of the annular rubber soundproof cover 3 is larger than the diameter of the wind turbine pile 14 to be constructed, so that the portion of the wind turbine pile 14 located below seawater during construction can be enclosed within the annular rubber soundproof cover 3. The annular rubber soundproof cover 3 further isolates construction noise from propagating into the seawater, enhancing the sound insulation and noise reduction effect. In this embodiment, the annular rubber soundproof cover 3 is made of a high-polymer sound-absorbing rubber material, such as high-strength polyethylene sound insulation material. Specifically, the annular rubber soundproof cover 3 has a diameter of 11m, a height of 22m, a wall thickness of 5cm, and a weight of approximately 45t.

[0043] This utility model discloses a noise reduction and sound insulation device for offshore construction. An annular rubber soundproof cover 3 is installed on one side of the pile stabilization platform, and a bubble tube 4 is installed on the lower outer periphery of the annular rubber soundproof cover 3. During construction, the wind turbine pile 14 is enclosed within the annular rubber soundproof cover 3. Simultaneously, before construction, an air compressor 5 is started to inject compressed air into the bubble tube 4. In this way, the annular rubber soundproof cover 3 effectively isolates the noise generated during the installation of the wind turbine pile 14. At the same time, the bubble tube 4 generates a bubble curtain around the annular rubber soundproof cover 3. Through the dual sound insulation and noise reduction effect of the annular rubber soundproof cover 3 and the bubble curtain generated by the bubble tube 4, the noise level generated during the installation of the wind turbine pile 14 can be significantly reduced, effectively protecting marine life and ensuring the smooth progress of offshore wind power construction.

[0044] Furthermore, in this embodiment of the invention, an anti-sinking plate 6 is also connected to the pile stabilization platform, and the lower part of the annular rubber soundproof cover 3 overlaps on the anti-sinking plate 6. Because the annular rubber soundproof cover 3 has a large weight, the anti-sinking plate 6 provides support to the lower side of the annular rubber soundproof cover 3, preventing it from sliding down and strengthening its fixation. In addition, only a small portion of the lower side of the annular rubber soundproof cover 3 needs to overlap the anti-sinking plate 6, so as not to affect the sinking construction of the wind turbine pile 14 within the annular rubber soundproof cover 3. In this embodiment, the anti-sinking plate 6 is symmetrically arranged on the four sides of the pile stabilization platform to ensure that the force on each part of the platform is even, avoiding instability caused by uneven weight distribution. If necessary, counterweights can also be installed on the pile stabilization platform.

[0045] Further, the first connecting component for connecting the annular rubber soundproof cover 3 in this embodiment includes: two symmetrically arranged distribution beams 7, multiple first tie bolts 8, and a clamp saddle 9. The two distribution beams 7 are respectively arranged on both sides of a crossbeam 2; each first tie bolt 8 passes through the distribution beam 7 and the crossbeam 2 and fixes the distribution beam 7 and the crossbeam 2; the clamp saddle 9 is connected to the distribution beam 7 on the side closer to the annular rubber soundproof cover 3. Specifically, the specifications of the distribution beam 7 in this embodiment are 2HM588×300, with a length of 25m. The two distribution beams 7 are fixed by multiple first tie bolts 8 (i.e., precision-rolled threaded steel) on the inner and outer sides of the crossbeam 2. The clamp saddle 9 can be welded to the distribution beam 7 on the side closer to the annular rubber soundproof cover 3, that is, the clamp saddle 9 is welded to the outer distribution beam 7. The clamp saddle 9 includes two semi-circular clamp parts on the left and right. The two semi-circular clamp parts are connected and fixed by bolts. During construction, after the annular rubber soundproof cover 3 is installed in place, the other semi-circular clamp part is installed. The inner and outer clamps are connected and fixed by bolts.

[0046] Furthermore, in this embodiment of the invention, at least two first connecting components are provided along the height direction of the annular rubber soundproof cover 3. Multiple first connecting components are used to more stably fix the annular rubber soundproof cover 3 to one side of the stabilizing platform.

[0047] Furthermore, the second connecting assembly for connecting the bubble tube 4 in this embodiment of the invention includes: multiple angle steels (not shown in the figure), multiple second tie bolts 10, and multiple steel wire ropes (not shown in the figure). The multiple angle steels are spaced apart on the outer periphery of the annular rubber soundproof cover 3. Each angle steel includes an L-shaped horizontal plate and a vertical plate. The bubble tube 4 is placed on the horizontal plate of the multiple angle steels, that is, the horizontal plate of the multiple angle steels provides support for the bubble tube 4. The vertical plate of each angle steel is fixedly connected to the annular rubber soundproof cover 3 by a second tie bolt 10. The multiple steel wire ropes are used to bind and fix the bubble tube 4 to the horizontal plate of the multiple angle steels. In this way, the bubble tube 4 can be fixed around the lower outer periphery of the annular rubber soundproof cover 3 by the cooperation of multiple angle steels, multiple second tie bolts 10, and multiple steel wire ropes, so as to form a bubble curtain around the annular rubber soundproof cover 3.

[0048] Furthermore, the noise reduction and sound insulation device of this embodiment also includes multiple steel connectors 11, one end of which is welded to the stabilizing platform, and the other end is welded to an angle steel. By adding the steel connectors 11, the fixing effect on the annular rubber sound insulation cover 3 and its outer peripheral bubble tube 4 can be further enhanced. The steel connectors 11 can be I-shaped steel.

[0049] Furthermore, the annular rubber soundproof cover 3 of this embodiment of the invention is provided with a lifting hole on its upper side. Lifting points are welded on the column 1. During construction, two 30-ton hand-operated hoists can be used to connect the lifting points to the lifting hole of the annular rubber soundproof cover 3 to complete the lifting and installation of the annular rubber soundproof cover 3.

[0050] Furthermore, in this embodiment, along the height direction of the annular rubber soundproof cover 3, multiple X-shaped reinforcing brackets 12 are connected between two adjacent columns 1 to enhance the load-bearing capacity and stability of the pile stabilization platform.

[0051] Furthermore, in this embodiment, a pile gripper 13 for fixing the wind turbine pile 14 is also connected to the pile stabilization platform. The pile gripper 13 is located on the upper side of the annular rubber soundproof cover 3 to fix and position the wind turbine pile 14 during construction. The pile gripper 13 can adopt an existing structure.

[0052] Before construction, the noise reduction and sound insulation device of this utility model requires the pile stabilization platform to be transported to a steel structure processing plant near the wind farm to complete the fixed installation of the annular rubber sound insulation cover 3 and the bubble tube 4. Due to the addition of the annular rubber sound insulation cover 3 and the bubble tube 4, during the construction process, when the wind turbine pile 14 is being fed, the wind turbine pile 14 needs to be lifted to a height above the annular rubber sound insulation cover 3. After the pile driving is completed, when the pile stabilization platform is dismantled, the entire pile stabilization platform needs to be lifted to a height above the top elevation of the pile.

[0053] This utility model embodiment involves installing an annular rubber soundproof cover 3 and a bubble tube 4 on the foundation pile stabilization platform of an offshore wind turbine foundation or a booster station foundation to ensure noise reduction during the foundation pile driving process. Through multiple tests, the noise can be reduced by nearly 20 decibels, effectively protecting marine life.

[0054] The noise reduction and sound insulation device of this utility model has a reasonable structure, light weight, and is easy to install, and can be widely used for noise reduction of offshore wind power foundations.

[0055] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
