Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, in particular to a benthic animal habitat device. Background Art

[0002] River and lake ecosystems are composed of communities of algae, aquatic plants, zooplankton, benthic animals, and fish. The pore structures in natural river channels serve important ecological functions, providing shelter and nesting conditions for fish, slowing flow, shading sunlight, and providing passageways. This is especially true during flood season, when river flows increase. Fish prefer pores as habitats, often taking refuge in these pores at the riverbed. However, traditional riverbank protection projects often employ rigid masonry structures, such as concrete retaining walls or mortar-laid stone masonry, to ensure the structural safety and durability of the bank slopes. These structures damage the habitats of fish and other aquatic organisms, impacting the health of river ecosystems.

[0003] In existing technologies, fish nests are typically stacked together to create fish habitats through the gaps between and cavities within the fish nests. Benthic animals are also a crucial link in the food chain, connecting the upper and lower reaches of the food chain. Currently, artificial habitat technologies and products are mostly designed to meet the needs of fish. Benthic animals typically reside in pebbles, silt, or sandy bottoms. Cement-made fish nests are not suitable as habitats for benthic animals. Furthermore, fish nests are not stable when arranged underwater and are prone to rolling over. Summary of the Invention

[0039] Benthic animals are a crucial link in the food chain, serving as a link between the upper and lower reaches of the food chain. Current artificial habitat technologies and products are mostly designed to meet the needs of fish. However, benthic animals typically reside on pebbles, silt, or sandy bottoms. Cement-made fish nests are not suitable as habitats for benthic animals. Furthermore, fish nests are not stable when arranged underwater and are prone to rolling over.

[0040] In view of this, if Figure 1-Figure 5 As shown, the benthic animal habitat device provided by the embodiment of the present invention includes: a brick body 100 and a habitat medium 200; the brick body 100 is provided with a receiving cavity, the opening of the receiving cavity is set upward, the habitat medium 200 is arranged in the receiving cavity, the habitat medium 200 is connected to the brick body 100, and the habitat medium 200 is used to provide a living environment for benthic animals; a protrusion 300 is provided at one end of the brick body 100, and a recess 400 is provided at the other end of the brick body 100, so that two adjacent brick bodies 100 can be connected through the protrusion 300 and the recess 400.

[0041] The benthic animal habitat device provided by the embodiment of the present invention includes: a brick body 100 and a habitat medium 200; a receiving cavity is provided in the brick body 100, the opening of the receiving cavity is set upward, the habitat medium 200 is set in the receiving cavity, the habitat medium 200 is connected to the brick body 100, and the habitat medium 200 is used to provide a living environment for benthic animals, so that benthic animals can enter the habitat medium 200 from the opening of the receiving cavity to live; a protrusion 300 is provided at one end of the brick body 100, and the brick body A recess 400 is provided at the other end of 100 so that two adjacent brick bodies 100 can be connected through the protrusion 300 and the recess 400, making the connection of multiple brick bodies 100 more stable, solving the technical problems in the prior art that cement-made fish nest bricks are not suitable as habitats for benthic animals, and that fish nest bricks are not firm and prone to rolling during the arrangement on the bottom of the water. The technical effect of ensuring that adjacent fish nest bricks are stably connected and not prone to rolling, and providing a habitat for benthic animals, is achieved.

[0042] Regarding the structure and shape of the brick body 100, specifically:

[0043] The brick body 100 can be set as three spaces or as multiple spaces. The brick body 100 includes a first compartment 110, a second compartment 120 and a third compartment 130. The first compartment 110, the second compartment 120 and the third compartment 130 are all provided with a receiving groove. The opening direction of the first compartment 110, the second compartment 120 and the third compartment 130 is set upward, and the brick body 100 can be cast with reinforced concrete. The bottom of the brick body 100 is sealed with reinforced concrete, leaving only an opening at the top, and the second compartment 120 is located between the first compartment 110 and the third compartment 130. There are protrusions 300 and recesses 400 at both ends of the second compartment 120. A protrusion 300 is provided at one end of the chamber 120, and a recess 400 is provided at the other end. The protrusion 300 and the recess 400 both penetrate along the height direction of the brick body 100 and extend along the width direction of the brick body 100. The protrusion 300 and the recess 400 have the same shape and the same size. There are inclined surfaces on both sides of the protrusion 300 and the recess 400. Each two inclined surfaces are arranged opposite to each other, so that when the protrusion 300 extends into the recess 400, the inclined surfaces on the protrusion 300 and the inclined surfaces on the recess 400 correspond to each other, preventing the two adjacent brick bodies 100 from sliding relative to each other after assembly. At the same time, it is more labor-saving and easier to position during assembly, making the connection between the brick bodies 100 more secure.

[0044] Regarding the habitat medium 200 and the aquatic plants 500, specifically:

[0045] The habitat medium 200 adopts a medium that benthic animals like. In this embodiment, the habitat medium 200 includes pebbles 210, fine sand 220 and planting soil 230, wherein the pebbles 210 can adopt natural pebbles 210 with a diameter of 8 cm to 16 cm. Since the pebbles 210 are easy to attach microorganisms and algae, they provide a good foraging place for aquatic insects among benthic animals. The pebbles 210 are placed in the first compartment 110 and connected to the outside world through multiple circular holes 600 on the side wall of the first compartment 110, so that aquatic insects can eat and settle in the pebbles 210 and migrate through the multiple circular holes 600 on the side wall. Fine sand 220 or silt can be placed in the second compartment 120. The second compartment 120 with a silt bottom mainly contains It is suitable for settling oligochaetes, chironomids and other insect larvae, and is mainly suitable for burrowing benthic animals. When the water flow rate is low, the sandy bottom can accommodate shrimps, bivalves, gastropods and chironomid larvae, etc. The third compartment 130 contains planting soil 230, on which aquatic plants 500 are planted. The aquatic plants 500 may include submerged plants or emergent plants. The bottom of the aquatic plants 500 is a habitat preferred by some benthic animals, and the fallen leaves produced by the aquatic plants are also one of the main food sources for benthic animals. The surface of the habitat medium 200 is flush with the surface of the brick body 100, making the overall paving smoother. At the same time, sufficient medium is stored inside the accommodating groove, and benthic animals can access the habitat medium 200 in time.

[0046] In actual use, the paving diagram is as follows Figure 4 and Figure 5 As shown, when paving along a straight line on the riverbed, each protrusion 300 is stuck in a groove, while in a curved paving environment, it can be as follows Figure 5 As shown, since the protrusion 300 and the groove adopt the shape of a gear, the gear shape design can also be staggered at a certain angle during assembly to adapt to the irregular changes of the river and lake shoreline.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
