Description

Technical Field

[0002] In coastal or offshore projects, breakwaters or sand dikes are usually set up to prevent strong waves or strong currents from invading the port area, as well as mud and sand intrusion, which may affect the normal navigation of ships.

[0003] There are three types of wave and sand prevention structures commonly used at present. The first type is a dam structure, which is cast in concrete and has a good effect on blocking waves and mud. However, the manufacturing cost is high, and the seawater on both sides of the dam is intercepted, which will have a certain impact on the local ecological environment; the second type is stacked with multiple types of convex stone piers, and the locking force generated by the stacking makes more stone piers bind each other to cope with the scouring of waves, but this structure is more troublesome to install and maintain. It is necessary to destroy its stacking structure, take it out, and then put it back in and lock it, and the anti-sand effect of this structure is weak; the third type is designed with plastic products connected in series in the middle of the coast by ropes, which can also have a certain wave-proof effect, but it cannot prevent sand, and also because the plastic products are connected in series by ropes, they need to be disassembled as a whole when replaced, which is not convenient, and the wave-proof effect is also limited by volume, and the upper limit is weak.

The first wave-proof block 11, the intermediate block 12 and the second wave-proof block 13 are all arranged in multiple groups at equal intervals from left to right, and the wave-proof component is also provided with a connecting component for connecting the first wave-proof block 11, the intermediate block 12 and the second wave-proof block 13.The sand-proof component is connected to the vertical closing component and the wave-proof component respectively. The sand-proof component is used to prevent mud and sand from passing through while ensuring the passage of fish. The fixing rod 1 is used to provide support. The cross bar 2 is further fixed to the fixing rod 1 by connecting with the coast to avoid installation tilt. Before construction, the vertical surface flatness of both sides of the coast needs to be ensured. The device is suitable for sea areas not exceeding ten meters deep. The sub-moulds 3 are interconnected to seal the positions on both sides of the coast. At the same time, the split design can also simplify the disassembly operation, which is convenient for the independent disassembly of the sub-moulds 3 at each position. The fixing bolt 4 cooperates with the closing cover 5 to facilitate the installation and disassembly of two adjacent sub-moulds 3. At the same time, the fixing bolt 4 and the closing cover 5 can be used to fix the rope 10. The rope 10 is straightened by setting a rope knot on its outside. The end cover 6 can be opened to place fillers in the sub-mould 3, such as sponge, concrete, foam and other materials, to change The buoyancy it is subjected to in seawater, the vertical rod groove 7 and the transverse rod groove 8 are respectively used for the passage of the fixing rod 1 and the cross bar 2 to avoid interference during the installation process, the interlayer 16 is used to facilitate the connection and fixation of the split mold 3 and the cross plate 17 there, the first wave-breaking block 11, the middle block 12 and the second wave-breaking block 13 constitute a wave-breaking unit, and by disassembling the wave-breaking unit into three parts, it can be convenient to install it on the outside of the rope 10, and the operation of disassembly can also be simplified.

[0035] Furthermore, the closing cover 5 is cup-shaped, and a thread is provided on the inner side of the closing cover 5. One end of the closing cover 5 is fixedly connected to an end plate for limiting the knot. The closing cover 5 can cooperate with the fixing bolt 4 to lock the split mold 3, and can also be used to connect the knot at the same time. It is easy to use and has many functions.

[0036] Furthermore, a U-shaped groove is provided at the bottom of the split mold 3. When the upper and lower split molds 3 are in contact, the port on the lower split mold 3 is located on the inner side of the U-shaped groove at the bottom of the upper split mold 3. The U-shaped groove can avoid interference when the upper and lower split molds 3 are connected, and can easily avoid interference with the upper and lower layers of the split molds 3 during disassembly, thereby facilitating the disassembly operation.

[0040] Furthermore, the top and bottom of the curved frame 18 are both provided with downwardly concave curved sections, and the lateral length of the curved frame 18 is smaller than the length of the transverse plate 17. The curved sections can facilitate the up and down flow of fish when passing through, and facilitate shaking off the mud and sand around them, thereby reducing the amount of mud and sand passing with the fish and improving the anti-sand effect.

[0041] Furthermore, one end of the fixing rod 1 is inserted into the bottom of the coast, and a through hole is opened on the outer side of the fixing rod 1 perpendicular to the axial direction.

Rope grooves 15 distributed up and down are arranged on one side of the first wave-breaking block 11 and the second wave-breaking block 13 and on the front and rear sides of the middle block 12. The rope grooves 15 can facilitate the installation of the wave-breaking unit on the outside of the two ropes 10, thereby improving the tightness during installation.
