Description

Technical Field

[0001] The utility model relates to the technical field of dike engineering, in particular to a novel prefabricated wave-breaking block. Background Art

[0002] Generally speaking, the embankment slope will be eroded by water flow and beaten by waves for a long time. Especially in the flood season and severe weather conditions such as typhoons, the embankment slope will be subjected to huge impact and pressure. In order to prevent these risks, prefabricated blocks will be laid on the surface of the embankment slope to reduce the erosion effect of water waves on the embankment slope.

[0003] For example, a new type of prefabricated wave-breaking ecological block in front of the dike with the publication number "CN219327041U" has high safety and can effectively reduce the construction elevation of the seawall. By starting to break waves and reduce waves in the area in front of the dike, the waves can reduce part of their energy when reaching the slope, reducing the task of breaking waves and reducing waves that the seawall needs to undertake, thereby reducing the construction elevation of the seawall and improving the viewing effect inside the city. With good stability, the wave force that the prefabricated wave-breaking ecological block needs to bear can be well transferred to the ground, piers and gravel behind the piers, so that the prefabricated wave-breaking ecological block can maintain good stability and can be guaranteed not to move in the face of large winds and waves, and has high structural stability. With good ecological effect, the prefabricated wave-breaking ecological block adopts a porous form, which can generate strong upwelling and provide a complex water environment. The setting of a micro tidal pool can provide animals, plants and microorganisms with a suitable habitat, which can effectively reduce the damage of hard structures to the marine ecosystem;

[0004] During use, multiple prefabricated blocks are placed in sequence on the edge of the seawall to bear the impact of waves. However, since the edges and corners of the prefabricated blocks are impacted by waves for a long time, they are prone to damage. At the same time, there is a lack of connection structure between multiple prefabricated blocks, so when encountering larger waves, one of the prefabricated blocks is easily washed away, resulting in poor overall anti-scouring and wave-breaking effect.

[0005] Therefore, we proposed a new type of wave-breaking prefabricated block that can solve the above problems well. Utility Model Content

[0006] The purpose of the utility model is to provide a new type of wave-breaking prefabricated block to solve the problem raised in the above-mentioned background technology that the edges and corners of the prefabricated blocks are easily damaged due to the impact of waves for a long time, and there is a lack of connection structure between multiple prefabricated blocks, so that when encountering large waves, a certain prefabricated block is easily washed away, resulting in poor overall anti-impact and wave-breaking effect.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel wave-breaking prefabricated block, comprising a prefabricated block body, one side of the prefabricated block body is fixedly connected with a first connecting block, and the other side of the prefabricated block body is fixed with a second connecting block, and the corners of the outer side of the prefabricated block body are all provided with chamfers;

[0011] Preferably, the docking block and the docking slot are located correspondingly, and the docking block and the docking slot are snap-fitted together.

[0012] Preferably, the rack is slidably connected to the first connecting block, the driven gear is rotatably connected to the first connecting block, and the driven gear is meshingly connected to the rack and the gear block.

[0013] Preferably, the positions of the rack and the slot correspond to each other, and the rack and the slot are snap-fitted together, and a limiting slot is provided on the side surface of the left end of the rack.

[0014] Preferably, the upper and lower ends of the second connecting block are slidably connected to limit rods, and one end of the two limit rods passes through the interior of the second connecting block, and return springs are installed between the outer sides of the two limit rods and the inner wall of the second connecting block.

[0015] Preferably, one end of the limiting rod extending into the second connecting block is in contact with the left end of the rack, and the positions of the limiting rod and the limiting groove correspond to each other.

[0016] Preferably, through holes are opened at equal angles on the outer side of the prefabricated block body, and the energy of water waves can be effectively reduced by utilizing multiple through holes.

[0017] Compared with the prior art, the beneficial effects of the utility model are: the new type of wave-breaking prefabricated block adopts a new structural design, and its specific contents are as follows:

[0018] (1) By setting the hook ring, the crane can lift the entire prefabricated block body through the hook ring and lay it flat along the seawall, thereby solving the disadvantages of difficult lifting of the prefabricated block body and easy damage of the edges and corners. At the same time, the docking block on the second connecting block is inserted into the docking groove on the second connecting block to preliminarily complete the installation of the two prefabricated block bodies. Then, the tooth block on the docking block drives the meshing driven gear to rotate, and the driven gear drives the rack to move and snap into the corresponding slot. Therefore, the double locking of the docking block and the rack can improve the firmness of the connection between the two prefabricated block bodies, and make the prefabricated block body have good anti-scouring and wave-breaking effect and convenient construction;

[0019] (2) When the rack is inserted into the slot, the limiting rod can be squeezed to move the limiting rod. When the position of the limiting rod corresponds to the position of the limiting slot, the limiting rod is reset under the elastic force of the reset spring and inserted into the corresponding limiting slot, thereby limiting the rack;

[0020] Furthermore, when the two prefabricated block bodies need to be separated, the limiting rod is pulled to separate the limiting rod from the limiting groove, so that the limiting of the rack can be released, and then the first connecting block and the second connecting block are pulled outward to separate the docking block from the docking groove, and drive the driven gear to reverse, and then the rack is reset and separated from the slot, so as to facilitate the separation of the two prefabricated block bodies;

[0021] (3) By providing the through holes, the energy of the water waves can be effectively reduced when the water waves hit the surface of the prefabricated block body. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] When in use, the hook ring 14 is set, so that the crane can lift the entire prefabricated block body 1 through the hook ring 14 and lay it flat along the edge of the seawall, thereby solving the difficulty in lifting the prefabricated block body 1. At the same time, the chamfer is used to avoid damage to the edges and corners of the prefabricated block body 1. Then the staff inserts the docking block 5 on the second connecting block 4 into the docking groove 6 on the first connecting block 3, and preliminarily completes the installation of the two prefabricated block bodies 1. At this time, the tooth block 12 on the docking block 5 drives the meshing driven gear 8 to rotate forward, and at the same time, the driven gear 8 drives the rack 7 to move and snap into the corresponding slot 9, so that the double locking of the docking block 5 and the rack 7 can improve the firmness of the connection between the two prefabricated block bodies 1, thereby making the prefabricated block body 1 have good anti-scouring and wave-breaking effects and convenient construction.
