[0001] The utility model relates to the technical field of fish trough bricks, in particular to an ecological fish trough brick. Background Art

[0002] With the development of shipping, during the construction projects such as waterway management, river dredging, damming and reef blasting, due to the changes in the water flow environment, water depth and riverbed quality near the river, fish have lost their habitats, and fish eggs in the breeding period cannot complete attachment and hatching in the new environment, and their numbers have begun to decrease. At the same time, with the increase in ships, fish are easily affected by the impact of ship wakes during migration or cannot rest and get nutrition in time and die, which eventually leads to the decline of the river's ecological environment.

[0003] At present, ecological fish trough bricks have appeared to provide fish with rest and improve the ecological environment. The fish can rest by cooperating with multiple fish trough bricks. However, most of the current fish trough bricks are cast with ordinary silicate concrete as the main body. The production cycle of this type of fish trough bricks is long, and the green and low-carbon effect is poor. In addition, most fish trough bricks are solid structures with smooth surfaces. Water plants cannot attach to the fish trough bricks, so they cannot meet the requirements of the fish habitat. At the same time, after the fish in the breeding period lay fish eggs, the fish eggs cannot attach to the water plants or the walls of the fish trough bricks, which is not conducive to the survival of fish. At the same time, the alkalinity of the material is relatively high, and the alkaline substances released by the material make the pH around the fish trough higher than that of normal water, affecting the formation of biofilms and algae thereon, which is not conducive to the survival of fish.

[0004] As can be seen from the above, there is a problem in the prior art that the fish tank bricks cannot meet the habitat conditions of fish. Utility Model Content

[0005] The main purpose of the utility model is to provide an ecological fish tank brick to solve the problem that the fish tank brick in the prior art cannot meet the living conditions of fish.

[0007] Furthermore, the trough body comprises a cage cover and a cage body, the cage cover is detachably connected to the cage body, and the cage body has an accommodating space.

[0008] Furthermore, the pore diameter of the mesh is smaller than the average diameter of the filler.

[0009] Furthermore, the cage body and the cage cover are both mesh structures woven with steel wires.

[0010] Furthermore, the ecological fish tank brick also includes a water plant fixing hook, which is arranged on the tank body, and the two ends of the water plant fixing hook are respectively a connecting end and a fixing end, the connecting end is arranged in the accommodating space, and the fixing end is located outside the accommodating space.

[0011] Furthermore, the diameter of the connecting end is larger than the pore diameter of the grid, and the fixed end is provided with a bending section, which is used to fix the aquatic plants.

[0012] Furthermore, there are multiple waterweed fixing hooks, and the multiple waterweed fixing hooks are arranged on the trough body at intervals.

[0013] Furthermore, the ecological fish tank brick also includes a bait assembly, which is arranged on the inner wall and is used to lure fish passing through the ecological fish tank brick.

[0014] Furthermore, the ecological fish tank brick also includes a water purification component, which is located on the outer side wall.

[0025] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0026] In order to solve the problem that the fish trough bricks in the prior art cannot meet the living conditions of fish, the utility model provides an ecological fish trough brick.

[0027] like Figure 1 to Figure 2 As shown, the ecological fish tank brick includes a tank body 10, which is a U-shaped structure with a grid. An accommodating space is formed between the inner wall and the outer wall of the tank body 10, and a filler 20 is arranged in the accommodating space.

[0028] By setting the trough body 10 of the fish trough brick into a U-shaped structure and placing a filler 20 between the two side walls of the trough body 10, the entire fish trough brick is transformed into a U-shaped stone cage structure. Fish can enter the middle space of the U-shaped structure to rest when migrating. At the same time, the trough body 10 has a grid, and the filler 20 is irregularly distributed in the accommodating space, making the surface of the fish trough brick rougher and rich in pore distribution, which is conducive to the attachment of biofilms and algae, providing a food source for fish while also facilitating the attachment of fish eggs, thereby meeting the habitat conditions of fish.

[0029] like Figure 1As shown, the tank body 10 includes a cage cover 11 and a cage body 12. The cage cover 11 is detachably connected to the cage body 12, and the cage body 12 has an accommodating space.

[0030] Specifically, the edge of the cage cover 11 and the edge of the cage body 12 are connected by steel wires or screws. The cage cover 11 is a U-shaped structure, and the middle opening can be adjusted according to actual conditions. The cage body 12 is a cage-shaped structure with a certain volume. The volume of the middle opening of the cage body 12 can meet the sizes of various fish. Optionally, a plurality of connecting limit structures are provided on the cage cover 11 to facilitate the combination of multiple fish trough bricks to form different fish trough structures. Any two adjacent ecological fish trough bricks can be arranged at intervals, and a plurality of ecological fish trough bricks are arranged on the top, which can provide a resting place for fish and provide a plurality of entry and exit channels, so that smaller fish can avoid being hunted by natural enemies.

[0031] In another undisclosed embodiment of the present application, an entry and exit channel is provided on the bottom periphery of the cage body 12 to allow fish to enter and exit freely, so that fish of different sizes can quickly enter and exit the hollow area and avoid natural enemies.

[0032] In this embodiment, the cage body 12 and the cage cover 11 are both mesh structures woven with steel wires.

[0033] Specifically, the cage body 12 and the cage cover 11 are woven into a mesh structure by steel wires of the same size, and a plurality of grids on the mesh structure are arranged in a rhombus. The cage body 12 woven with steel wires is not easily deformed when subjected to a certain collision. The diameter of the steel wire can be 2 to 4 mm. By weaving with completely identical steel wire structures, it can be ensured that the force limits of various parts of the cage body 12 are similar. Optionally, the steel wire diameter of the cage body 12 is larger than that of the cage cover 11. Since the weight of the filler 20 is mainly borne by the cage body 12, the cage body 12 needs to be able to withstand greater force.

[0034] In this embodiment, the pore diameter of the mesh is smaller than the average diameter of the filler 20 .

[0035] Specifically, the filler 20 is in the shape of particles of different sizes, and the fillers 20 of different sizes are irregularly arranged in the accommodating space. The pores of the grid are smaller than the average diameter of the filler 20, so that part of the filler 20 can extend out of the cage body 12 and the cage cover 11. Through this arrangement, part of the algae can be attached to the extended filler 20, which is convenient for larger fish to eat and replenish energy. At the same time, the roughness of the surface of the trough body 10 is further increased. The pores of different specifications formed can meet the survival needs of newly hatched fry, thereby improving the effect of the ecological fish trough brick. Optionally, the pore size of the grid of the cage body 12 and the cage cover 11 is smaller than the diameter of any filler 20.

[0036] like Figure 2As shown, the ecological fish tank brick also includes a water grass fixing hook 30, which is arranged on the tank body 10. The two ends of the water grass fixing hook 30 are respectively a connecting end 31 and a fixing end 32. The connecting end 31 is arranged in the accommodating space, and the fixing end 32 is located outside the accommodating space.

[0037] Specifically, the water grass fixing hook 30 is arranged on the inner and outer walls of the trough body 10, and the connecting end 31 is accommodated in the accommodating space. The water grass fixing hook 30 also includes a transition section 33. The connecting end 31 and the fixed end 32 are respectively detachably connected to the transition section 33. In actual use, the connecting end 31 is first placed in the accommodating space, and the transition section 33 is connected to the connecting end 31 and then extends out of the trough body 10 to connect with the fixed end 32. Then, the filling material 20 is put in and the cage cover 11 is covered to complete the assembly of the ecological fish tank brick.

[0038] In this embodiment, the diameter of the connecting end 31 is larger than the pore diameter of the grid, and the fixing end 32 is provided with a bending section, which is used to fix the water plants.

[0039] Specifically, the connecting end 31 is a cylindrical structure, and the diameter of the connecting end 31 is larger than the diameter of the grid to facilitate fixing the water grass fixing hook 30 on the trough body 10. The fixing end 32 is provided with an arc-shaped bending section for fixing the floating water grass near the trough body of the ecological fish tank brick. The diameter of the transition section 33 is smaller than the diameter of the grid to facilitate the transition section 33 to move along the grid.

[0040] In this embodiment, there are a plurality of waterweed fixing hooks 30 , and the plurality of waterweed fixing hooks 30 are arranged at intervals on the trough body 10 .

[0041] Specifically, the water grass fixing hooks 30 are arranged in multiple rows on the outer wall of the cage body 12. The arrangement of multiple water grass fixing hooks 30 makes it easier to fix the water grass. At the same time, the water grass fixing hooks 30 can also provide a place for the attachment of biofilms and algae, thereby improving the food web structure near the ecological fish tank bricks. Optionally, water grass fixing hooks 30 are arranged on the inner wall of the tank body 10. In this embodiment, the water grass fixing hooks 30 are a smooth structure made of steel, thereby preventing the water grass fixing hooks 30 from scratching fish. At the same time, being made of steel can increase the service life of the water grass fixing hooks 30 and prevent the water grass fixing hooks 30 from being corroded by river water.

[0042] In this embodiment, the ecological fish tank brick also includes a bait assembly, which is arranged on the inner wall and is used to lure fish passing through the ecological fish tank brick.

[0043] Specifically, the bait assembly includes a hook and bait. One end of the hook is a smooth annular structure, and the bait is arranged on the annular structure. In the initial stage of the use of the ecological fish trough brick, it attracts fish to inhabit and provides energy to the fish to replenish their physical strength. The other end of the hook is a cylindrical chassis, and the cylindrical chassis is arranged in the accommodating space. The hook is fixed by the cylindrical chassis. Furthermore, there are multiple bait assemblies, and the multiple bait assemblies are arranged at intervals on the inner wall of the trough body 10. Optionally, bait assemblies are also arranged on the outer wall of the trough body 10. By increasing the number of bait assemblies, the normal use of the ecological fish trough brick in the early stage is guaranteed, and the speed of ecological improvement is accelerated.

[0044] In another optional embodiment of the present application, the bait ear in the bait assembly is arranged on the water grass fixing hook 30, thereby achieving the effect of inducing fish and reducing the parts and processing and construction cycle of the ecological fish tank bricks.

[0045] In this embodiment, the filling material 20 is concrete fragments.

[0046] Specifically, a large amount of concrete waste materials are generated during the process of river channel development and the demolition of bridges along the road. Waste materials with appropriate volumes are selected from the concrete waste materials as fillers 20 and placed in the accommodation space. In this way, the concrete waste materials are reasonably utilized, the cost of handling the concrete waste generated by river channel development is reduced, and the adverse impact of the waste materials on the surrounding environment is avoided. At the same time as the river channel development, ecological fish trough bricks are made. In this way, the secondary application of waste materials is achieved, the overall cost of the project is reduced, and the transformation of the ecological environment is realized, which can practice the green concept.

[0047] Furthermore, the use effect of recycled aggregate particles from waste concrete with a nominal particle size of 10-20 mm is the best.

[0048] In this embodiment, the ecological fish tank brick also includes a water purification component, and the water purification component is located on the outer side wall.

[0049] Specifically, the water purification component includes water purification materials and a gauze bag. The water purification material is contained in the gauze bag. The gauze bag is connected to the inner wall and the outer wall of the trough body 10 by connecting hooks so that the water purification component is washed away by the river water. Furthermore, there are multiple gauze bags, and the multiple gauze bags are arranged on the inner wall and the outer wall of the trough body 10 at intervals. Optionally, the gauze bag is a degradable material. After the water purification material in the gauze bag takes effect and decomposes, the gauze bag begins to gradually decompose, thereby avoiding causing artificial pollution of the river and generating waste garbage.

[0050] Specifically, the water purification material is pyrite (FeS2), iron ions (+2 valence) and S elements (mixed +6 valence and -2 valence), which can all be oxidized by microorganisms as electron donors in natural water bodies. The filler 20 used in this embodiment is concrete fragments. The acidity generated during the oxidation of pyrite (FeS2) can neutralize the alkalinity released by the concrete. At the same time, free iron ions can also drive the ammonia nitrogen oxidation reaction, reduce the ammonia nitrogen in the water body and the nitrogen generated by the aggregation and excretion of fish in the ecological fish tank bricks, reduce the risk of water rich oxidation, and generate active oxygen, which promotes the degradation of organic matter in the water and improves the nutrients in the water quality to further provide convenient conditions for fish and algae.

[0051] In another optional embodiment of the present application, the water purification material is mixed with the filler 20 and placed in the accommodating space of the tank body 10. In this way, the increase in the construction period caused by setting up multiple water purification components is avoided. At the same time, pyrite (FeS2) is decomposed after the reaction, and multiple pores are formed in the filler 20, which facilitates the attachment of fish eggs and algae microorganisms.

[0052] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: by setting the ecological fish trough brick including a trough body 10, the trough body 10 is a U-shaped structure with a grid, and a accommodating space is formed between the inner wall and the outer wall of the trough body 10, and a filler 20 is arranged in the accommodating space. By setting the trough body 10 of the fish trough brick into a U-shaped structure and placing the filler 20 between the two side walls of the trough body 10, the entire fish trough brick is turned into a U-shaped stone cage structure as a whole, and fish can enter the middle space of the U-shaped structure to rest when migrating. At the same time, the trough body 10 has a grid, and the filler 20 is irregularly distributed in the accommodating space, making the surface of the fish trough brick rougher and rich in pore distribution, which is conducive to the attachment of biofilms and algae, providing a food source for fish while also facilitating the attachment of fish eggs, meeting the living conditions of fish.
