[0019] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.
[0022] like Figure 1 As shown, a combined artificial fish reef suitable for ecological construction of seawalls according to a preferred embodiment of the utility model comprises a fish reef body 1, a sunshade grille 2 and a planting trough body 3. A first cavity 11 is hollow inside the fish reef body 1, an opening is provided at the upper end of the first cavity 11, and a sunshade grille 2 is embedded in the opening. The artificial fish reef is placed in the riprap area of the seawall. The bottom plate and the surrounding side plates of the fish reef body 1 are impermeable. During high tide, seawater can only enter the first cavity 11 through the gaps in the sunshade grille 2. After low tide, since the bottom plate and the surrounding side plates of the fish reef body 1 are impermeable, a certain amount of seawater can be stored in the first cavity 11, which has a certain water retention capacity and can provide a growth environment for organisms. In order to facilitate the installation of the fish reef as a whole, a planting trough 3 is provided on the outer wall of the fish reef body 1. The planting trough 3 is mainly used to provide a suitable growth environment for mangrove plants. Specifically, a second cavity 31 is provided in the hollow inside of the planting trough 3. Drain holes 32 connected to the second cavity 31 are provided on the side walls around the planting trough 3. An ecological bag for planting mangrove plants is provided in the second cavity 31. The drainage hole 32 is conducive to the discharge of seawater from the second cavity 31 during low tide, thereby ensuring the growth conditions of mangrove plants.
[0023] Further, in order to simplify the structure of the fish reef body 1, the fish reef body 1 is a cube. In this embodiment, the basic size of the fish reef body 1 is 1m*1m*1m. In order to facilitate the design of the sunshade grille 2, refer to Figure 3In this embodiment, the sunshade grille 2 includes a frame 21 and a crossbar 22. The crossbars 22 are evenly spaced in the frame 21, and the overall structure is simple. At the same time, in order to form a stable growth environment for benthic organisms in the fish reef body 1, refer to Figure 4 At the bottom of the first cavity 11, a partition 12 is provided, which divides the first cavity 11 into a plurality of compartments 13. The compartments 13 are filled with silt or fine sand to form a sandy and silty environment for the survival of benthic shellfish. When selecting silt or fine sand, the sediment environment of the area where the ecological construction of the seawall is to be implemented can be referred to. In order to ensure that each compartment 13 has a relatively independent space, the height of the partition 12 is greater than or equal to 30 cm, and the height of the partition 12 can be adaptively adjusted according to actual needs.
[0024] Furthermore, the eco-bag is used to provide mangrove plants with stable root growth conditions. The eco-bag includes a bag body, which is made of geotextile and filled with fertilizer and soil. After the eco-bag is placed in the second cavity 31, the seedlings of the mangrove plants are then planted in the eco-bag to ensure that the mangrove plants can grow. When the mangrove plants grow up, they can shield the fish reef body 1, further reducing the temperature of the first cavity 11, and providing favorable conditions for the subsequent growth of organisms on the rocks. At the same time, after the mangrove plants become a forest, the landscape and ecology of the waterside of the seawall are also improved.
[0025] Furthermore, in order to facilitate the positioning of the sunshade grille 2 and the fish reef body 1 during installation, the upper end surface of the sunshade grille 2 is flush with the upper end surface of the fish reef body 1. In order to facilitate the arrangement of the planting troughs 3, the planting troughs 3 are evenly distributed around the outer wall of the fish reef body 1. Figure 1 , Figure 2 The number of planting troughs is 4. Specifically, a limiting hole is provided on one side of the planting trough body 3 that fits the side wall of the fish reef body 1. A limiting boss corresponding to the limiting hole is provided on the side wall of the fish reef body 1, which is not shown in the figure. The limiting hole and the limiting boss are plugged in to realize the rapid installation and positioning of the fish reef body 1 and the planting trough. Furthermore, in order to simplify the structure of the planting trough, in this embodiment, the planting trough is a rectangular parallelepiped. Furthermore, in order to facilitate the design of the drainage hole 32, the shape of the drainage hole 32 is circular, elliptical or polygonal. In this embodiment, refer to Figure 1 For ease of processing, the drainage hole 32 is circular in shape.
[0026] In summary, the embodiment of the utility model provides a combined artificial fish reef suitable for ecological construction of seawalls, wherein a first cavity 11 is hollowed out inside the fish reef main body 1, and a sunshade grille 2 is embedded in the upper opening of the first cavity 11, and seawater can only enter and exit the first cavity 11 through the gap on the sunshade grille 2, which has a certain water retention capacity. In addition, the sunshade grille 2 can reduce the direct sunlight on the inside of the artificial fish reef, and provide a suitable living environment for organisms. A planting trough 3 is arranged outside the fish reef main body 1, and a second cavity 31 is hollowed out inside the planting trough 3, and an ecological bag is arranged in the second cavity 31, which is used to provide an environment suitable for the growth of mangrove plants, provide a growth space for mangrove plants, and reduce the impact of artificial seawalls on the intertidal zone ecology. At the same time, the plants in the planting trough 3 can also provide shade for the fish reef main body 1, further reduce the temperature of the fish reef main body 1, and provide a suitable living space for attached organisms.
[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
