They are divided into different types according to their location and function. Levee wave-breaking walls are walls set up at the front of the levee top to prevent waves from going over the levee top. Stable, solid and watertight wave-breaking walls can appropriately reduce the super-height of the levee and save the amount of dam construction work, but excessively high levee wave-breaking walls will also affect the viewing view of the landscape and people's water-friendly and near-water activities. Therefore, what kind of structure to use to avoid the adverse effects of excessively high levee wave-breaking walls, improve the landscape aesthetics of the levee, ensure passability while reducing the amount of levee filling, and ensure the wave-proof effect of the levee wave-breaking wall itself, so that it can be suitable for water levels at different times and heights, has become a major difficulty for engineers.

In order to better illustrate the present embodiment, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted, and the positional relationship described in the accompanying drawings is only used for illustrative purposes and cannot be understood as limitations on the present utility model.

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] The utility model provides a composite embankment top structure, including an embankment top base 1, a floating cavity 12 is provided on the upper part of the embankment top base 1, a first embankment top road 14 and a second embankment top road 15 are respectively left on both sides of the floating cavity 12, a water inlet channel 11 is provided on the water-facing side of the embankment top base 1, one end of the water inlet channel 11 is connected to the outside, and the other end is connected to the floating cavity 12, a floating wave-breaking wall 2 is provided in the floating cavity 12, and a rotating shaft device 3 is connected to the end of the floating wave-breaking wall 2 away from the water inlet channel 11, the upper surface of the floating wave-breaking wall 2 is flush with the upper surface of the embankment top base 1 and the bottom surface thereof is higher than the water inlet channel 11.

[0024] The dike top base 1 is a reinforced concrete structure.

[0025] A floating body 23 is provided inside the floating wave-breaking wall 2 .

[0026] like Figure 1~Figure 3 As shown, when the water level exceeds the water inlet channel 11 , water flows from the water inlet channel 11 into the buoyancy cavity 12 , first filling up the space below the floating wave-breaking wall 2 , and starting to generate buoyancy on the floating wave-breaking wall 2 .

[0027] The rotating shaft device 3 includes a connecting seat 31 located on both sides of the floating wave-breaking wall 2. The connecting seat 31 is mechanically anchored at the bottom of the floating cavity 12. The upper part of the connecting seat 31 is rotatably connected to a movable shaft 32, and the floating wave-breaking wall 2 can rotate and rise and fall around the movable shaft 32.

[0028] A plurality of anti-collision rubber pads 121 are further provided at the bottom of the buoyancy cavity 12 , and the anti-collision rubber pads 121 are located below the buoyancy type wave-breaking wall 2 .

[0029] A locking mechanism 4 of the floating wave-breaking wall 2 is also provided on one side of the floating cavity 12 away from the water inlet channel 11 .

[0030] The locking mechanism 4 is anchored on the top of the embankment base 1, and one end of the locking mechanism 4 is rotatably connected to a lock buckle 41. A locking plate 24 is provided on the end of the floating wave-breaking wall 2 close to the locking mechanism 4, and a locking groove 25 is provided on the top of the floating wave-breaking wall 2. The locking plate 24 and the locking groove 25 can respectively cooperate with the lock buckle 41 when the floating wave-breaking wall 2 is at different corresponding angles.

[0031] The locking mechanism 4 also includes a positioning seat 44 anchored inside the embankment base 1. The positioning seat 44 is provided with a receiving groove 43 for the lock buckle 41 on the side facing the floating cavity 12. One end of the positioning seat 44 is fixedly connected to a rotating shaft 42 of the lock buckle 41. The rotating shaft 42 vertically passes through the end of the lock buckle 41 located in the receiving groove 43. The lock buckle 41 can rotate horizontally around the rotating shaft 42 and completely rotate to the inside of the receiving groove 43.

[0032] The lock buckle 41 located below the locking plate 24 can lock the floating wave-breaking wall 2 in a horizontal position, and the lock buckle 41 located in the locking groove 25 can lock the floating wave-breaking wall in a vertical position.

[0033] Normally, if the water level line is always maintained below the embankment base 1, even if the water flows into the floating cavity 12 from the water inlet channel 11 and generates buoyancy on the floating wave-breaking wall 2, there is no need to raise the floating wave-breaking wall 2. Therefore, under normal circumstances, it is necessary to always place the lock buckle 41 of the locking mechanism 4 under the locking plate 24 of the floating wave-breaking wall 2 to lock the floating wave-breaking wall 2 in a horizontal position to prevent the floating wave-breaking wall 2 from being lifted at a small angle due to buoyancy, thereby affecting daily landscape viewing and other hydrophilic and near-water activities.

[0034] When the water level is too high and unstable, especially during the flood season, it is necessary to manually stand on the side of the second embankment top road 15 and rotate the lock buckle 41 of the locking mechanism 4 to store it in the accommodating groove 43. At this time, the floating wave-breaking wall 2 can be rotated and raised under the action of buoyancy. The height of the water level will affect the floating angle of the floating wave-breaking wall 2. When the floating wave-breaking wall 2 floats to the highest water level, the lock buckle 41 is inserted into the locking groove 25 on the floating wave-breaking wall 2, which can lock the floating wave-breaking wall 2 in a vertical position.

[0035] The outermost layer of the floating wave-breaking wall 2 is an acrylic plate layer 21, and the inner layer of the acrylic plate layer 21 is provided with a stainless steel frame 22. Inside the stainless steel frame 22, a plurality of separated accommodating cavities 221 are provided in the length direction of the floating wave-breaking wall 2, and a float 23 is provided in the accommodating cavity 221.

[0036] The outer wall of the stainless steel frame 22 is tightly fitted and fixed to the inner wall of the acrylic plate layer 21 .

[0037] The composite embankment top structure is arranged in sections at the structural joint position of the embankment top, and the section width is generally 10-20 cm. A water-stop rubber is fixed between two adjacent floating wave-breaking walls 2.

[0038] A trash rack 111 is provided at one end of the water inlet channel 11 communicating with the outside.

[0039] The floating body 23 is a plastic hollow buoy.

[0040] In this embodiment, two separated accommodating chambers 221 are provided in the stainless steel frame 22 along the length direction of the floating wave-breaking wall 2 .
