Description

Technical Field

[0001] The invention belongs to the technical field of breakwaters, and in particular relates to a flexible sea wall. Background Art

[0002] Breakwaters refer to structures built to resist waves, tsunamis, storm surges and other extreme weather conditions. They can protect the coast and marine structures behind them and maintain relatively calm sea conditions in the enclosed area. Traditional concrete rigid seawalls and breakwaters have difficulties such as high difficulty in foundation treatment, long construction period, and difficulty in repair after damage. Although researchers have proposed the use of curtains as the main wave-breaking structure, test results show that it has a good wave-breaking effect and can be used as an alternative to traditional rigid seawalls and breakwaters, thereby avoiding the repeated construction of rigid seawalls and breakwaters, and has significant economic value. However, the connection between the curtain and the water tank in the experiment and the curtain structure are relatively simple, making it difficult to apply to actual projects. Summary of the invention

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] As shown in the figure, a flexible sea wall comprises a floating body 1, which is connected to an anchor 15 fixed to the seabed 16 through a plurality of mooring cables 3, and also comprises a first curtain 2 and a second curtain 5. The first curtain 2 is connected to the bottom of the floating body 1, and two second curtains 5 with opposite inclination directions are connected downward to the bottom of the first curtain 2, and the lower parts of the two second curtains 5 are provided with a reeling mechanism fixed to the seabed 16. In this embodiment, the waves are blocked by using the form of curtains, and the curtains are arranged in sections, and the second curtains 5 are arranged on both sides of the bottom of the first curtain 2, so as to effectively reduce the influence of the waves on the sea area behind the curtains, and ensure the ability of the curtain to resist external forces as a whole, thereby ensuring the reliability of the use of the curtains; in addition, the reeling mechanism is arranged at the bottom of the second curtain 5, which can meet the use of sea areas of different depths and has strong adaptability; the first curtain 2 and the second curtain 5 are immersed in the seawater as a whole through the floating body 1 and the reeling mechanism fixed to the seabed 16, and the seawater is blocked to a certain extent, thereby greatly reducing the influence of the waves on the sea conditions in the enclosure area.

[0030] The bottom of the first curtain 2 and the top of the second curtain 5 are fixed together by the connecting ring 4, so the connecting ring 4 can transfer the tension in the first curtain 2 to the second curtain 5. In this embodiment, there are multiple connecting rings 4, which are evenly distributed, and each connecting ring 4 passes through the bottom of the first curtain 2 and the top of the second curtain 5 to bind the first curtain 2 and the second curtain 5 together. Of course, the bottom of the first curtain 2 and the top of the second curtain 5 can also be fixed to a longer connecting tube.

[0031] The two second curtains 5 are symmetrically arranged on both sides of the first curtain 2 .

[0032] The two reeling mechanisms are fixed to both sides of the connecting plate 12 , and a plurality of anchoring tubes 14 fixed to the seabed 16 are evenly fixed to the bottom of the connecting plate 12 , ensuring that the reeling mechanisms can be fixed to the seabed 16 , thereby ensuring that the second curtain 5 can be fixed to the seabed 16 .

[0033] The winding mechanism includes a tubular storage cover 6 horizontally arranged along the width direction of the second curtain 5, a through groove is opened on the surface of the storage cover 6, and the front and rear ends of the storage cover 6 are sealed. A rotatable shaft 7 is provided in the middle of the storage cover 6, and the second curtain 5 is wrapped around the shaft 7 and passes through the through groove.

[0034] Positioning rings (not shown) are fixedly connected in the middle of the front and rear side plates of the storage cover 6, and both ends of the rotating shaft 7 are inserted into the corresponding positioning rings, and a limit rod 9 is fixedly connected radially at one end of the rotating shaft 7. A torsion spring 8 is connected between the limit rod 9 and the corresponding side plate of the storage cover 6, and the unfolding and retracting state of the second curtain 5 is controlled by the torsion spring 8. In this embodiment, the two ends of the rotating shaft 7 and the positioning ring are connected together by bearings, which makes it easier for the rotating shaft 7 to rotate.

[0035] A plurality of retractable limit blocks 11 are evenly arranged on the circumferential inner wall of the storage cover 6 corresponding to the limit rod 9, and when the second curtain 5 is unfolded, the limit rod 9 can push open the corresponding limit block 11 during the rotation process with the rotating shaft 7, and the limit rod 9 can be limited by the limit block 11 adjacent to the limit rod 9 after being pushed open.

[0036] A connecting sleeve 10 is fixedly connected to the corresponding limit block 11 on the circumferential inner wall of the storage cover 6. The limit block 11 is connected to the connecting sleeve 10 through an elastic member. When the elastic member is in free extension, the outer end of the limit block 11 extends out of the connecting sleeve 10, and the inner end is located inside the connecting sleeve 10. One side of the outer end of the limit block 11 is set as an inclined surface structure. When the second curtain 5 is unfolded, the end of the limit rod 9 can contact the inclined surface and push open the limit block 11 during the rotation process. In addition, under the action of the last limit block 11 pushed open by the torsion spring 8 and the limit rod 9, the second curtain 5 can be tightened as much as possible.

[0037] The through slots on the two storage covers 6 are arranged opposite to each other, and the connecting plate 12 is fixed between the lower edges of the two through slots.

[0038] A plurality of support plates 13 inserted into the seabed 16 are evenly fixed to the bottom of the storage cover 6 along the radial direction. The support plates 13 can improve the ability of the storage cover 6 to resist lateral sliding, further ensuring the stability of the overall structure.

[0039] In this embodiment, mooring cables 3 are provided at the four corners of the bottom of the floating body 1. Of course, mooring cables 3 can also be provided at other positions of the floating body 1. The mooring cables 3 are in a taut state, allowing the floating body 1 to deviate to a certain extent under the action of loads such as waves and currents. The anchor 15 adopts a pile anchor, a drag anchor, a suction anchor or a gravity penetration anchor. The anchor cylinder 14 can be fixed in the seabed 16 in the form of a pile anchor, a suction anchor, a pile shoe foundation, etc. according to the different soil types of the seabed 16.

[0040] The working process of this embodiment is as follows:

[0041] In the initial stage of production, the second curtain 5 is rolled up into the storage cover 6 and only released for a short distance. When in use, the second curtain 5 is released according to the depth of the sea water, so that the first curtain 2 and the second curtain 5 completely block the sea water, and then the winding mechanism is fixed to the seabed 16 through the anchor cylinder 14, and the anchor 15 at the bottom of the mooring cable 3 is also fixed to the seabed 16 to complete the overall installation of the flexible sea wall. In the event of rising sea levels or extreme climates, the second curtain 5 can extend outward from the winding mechanism to extend the effective length of the second curtain 5, and during the extension process, the rotating shaft 7 is limited by the limit block 11 to prevent the second curtain 5 from being rolled up into the storage cover 6 again, which would cause the curtain height to be lower than the depth of the sea water and fail to effectively block the waves.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
