Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture water quality regulation, in particular to a mineral slow-release device for improving aquaculture water quality. Background Art

[0002] A balanced ratio of mineral elements in water bodies is the foundation of water quality and an important guarantee for the normal functioning of aquatic ecosystems. Under normal conditions, dissolved inorganic salts in water bodies are mainly provided by dissolution from rocks and soils, and are also supplemented by atmospheric dry deposition and rainwater wet deposition. Different climatic conditions also determine the amount of mineral elements added to aquaculture water bodies, which in turn affects the material metabolism of aquatic ecosystems: due to industrial development, waste gas emissions have increased, and rainwater acidification has greatly increased the dissolution and loss of mineral elements from terrestrial soils and rocks; global temperature rises, and warm weather reduces wind volume, atmospheric dry deposition and rainwater wet deposition will decrease, reducing the mineral element replenishment of natural water bodies and water bodies.

[0003] From the perspective of bioinorganic chemistry, bioinorganic elements are indispensable to aquatic ecosystems. For example, a significant portion of proteases in organisms are metalloproteases. Without these metal ligands, proteases cannot function properly. Consequently, a reduction in the supply of inorganic salts in aquaculture waters hinders the functioning of aquatic ecosystems. Furthermore, frequent aquaculture diseases and the emergence of new ones have resulted in significant losses for the aquaculture industry. For example, the recent outbreak of overwintering fish syndrome in various parts of southern China demonstrates the close connection between the two.

[0004] Developing micro-flow, land-based, barrel-based aquaculture in mountainous areas using reservoir water can improve the economic benefits of the aquaculture industry while protecting the reservoir's ecological environment. However, due to the varying mineral content of the source water and the high density of barrel-based aquaculture, while oxygenation can be used to meet demand, the aquaculture water still contains high concentrations of ammonia and nitrite nitrogen. Supplementing the water with mineral salts not only eliminates waste nitrogen pollution through photosynthesis but also promotes bacterial decomposition of organic waste in the water, making it a cost-effective method.

[0005] Therefore, developing a mineral slow-release device that can meet the needs of aquaculture, replenish the biological inorganic elements consumed in the water body, ensure the smooth material circulation and energy flow of the aquatic ecosystem, and thus ensure the stability of the aquatic ecosystem is of great significance to the improvement of aquaculture production and the realization of aquaculture benefits. Utility Model Content

[0006] Based on the above-mentioned prior art, the purpose of the utility model is to provide a mineral slow-release device for improving aquaculture water quality with a simple structure, reasonable design and easy use. It is accompanied by the gradual release of mineral salt regulators, breaking the balance between buoyancy and gravity, so that the release device is suspended and slowly released from bottom to top in the water. It can effectively eliminate the high ammonia nitrogen toxicity generated in the aquaculture water through photosynthesis, and play an important role in reducing the incidence of diseases and promoting the healthy growth of fish.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A mineral slow-release device for improving aquaculture water quality comprises a base, an air bag, a screw-on platform, a rotating connecting seat, a regulator storage tank, a mesh slow-release cover, a fixing ring and a cross bar; the upper end of the base is connected to the air bag, the lower surface of the base is provided with a screw-on platform with an integrated structure, the middle of the base is connected to a regulator storage tank hanging below via a connecting shaft, the outer wall of the regulator storage tank and the inner wall of the screw-on platform are movably connected, the screw-on platform is connected to the inner thread of the upper port of the mesh slow-release cover via an outer external thread, and a fixing ring is connected to the lower inner side of the mesh slow-release cover port, the middle of the fixing ring is connected to a cross bar, the side wall of the regulator storage tank is symmetrically provided with a circle of hollow slide grooves, and the cross bar is horizontally inserted into the hollow slide grooves of the regulator storage tank.

[0009] Preferably, the regulator storage tank is a hollow cylindrical structure.

[0010] Preferably, the inner diameter of the fixing ring corresponds to the outer diameter of the regulator storage tank, so that the fixing ring and the regulator storage tank are kept in a fitted state.

[0011] Preferably, the upward buoyancy of the airbag is consistent with the downward gravity of the regulator storage tank, the mesh slow-release cover, and the mineral salt regulator, so as to achieve overall suspension in water.

[0012] Preferably, the mesh slow-release cover can move up and down along the hollow chute on the surface of the regulator storage tank in cooperation with the cross bar, so as to realize the opening, closing and enlargement of the water inlet at the upper end of the mesh slow-release cover.

[0013] After adopting the above structure, the beneficial effects of the utility model are:

[0014] The device's specially designed slow-release structure allows the mineral salt regulator to slowly fall into the water under the influence of wind, waves, and water. The minerals in the regulator dissolve in the water, improving water quality. The release of the regulator disrupts the balance between buoyancy and gravity, allowing the release device to slowly release from bottom to top in the water. This slow-release action also replenishes mineral elements consumed in the water during the aquaculture process. This not only facilitates photosynthesis and eliminates waste nitrogen, resulting in fertile, fresh, and tender water, but also promotes bacterial decomposition of organic waste in the aquaculture system, reducing ciliate outbreaks in the aquaculture pond.

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments illustrated in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0023] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0024] See Figure 1-Figure 3As shown, the mineral slow-release device for improving aquaculture water quality of this embodiment comprises a base 1, an air bag 2, a screw-on platform 3, a connecting shaft 4, a regulator storage tank 5, a mesh slow-release cover 6, a fixing ring 7, a cross bar 8, and a mineral salt regulator 9. The upper surface of the base 1 is connected to the air bag 2, the lower surface of the base 1 is provided with a screw-on platform 3 of an integrated structure, the outer wall of the screw-on platform 3 is provided with an external thread for threaded connection, and the top of the regulator storage tank 5 is movably connected with the connecting shaft 4. By applying pressure to the tail of the regulator storage tank 5, the top of the connecting shaft 4 is clamped with the center of the lower surface of the base 1, which is convenient for subsequent disassembly and replacement. The outer diameter of the regulator storage tank 5 corresponds to the inner diameter of the screw-on platform 3, so that the top of the regulator storage tank 5 can be perfectly clamped in the screw-on platform 3. The external thread on the outer wall of the screw-on platform 3 cooperates with the internal thread provided on the inner wall of the upper port of the mesh slow-release cover 6 to realize the threaded connection between the mesh slow-release cover 6 and the base 1.

[0025] The regulator tank is a hollow cylindrical structure with a circle of hollow chutes symmetrically arranged on its sidewalls. A fixing ring 7 is clipped or fixedly connected below the internal threads of the mesh slow-release cover 6. A crossbar 8 is connected to the center of the fixing ring 7 and is laterally inserted into the hollow chute 10 in the center of the regulator tank 5.

[0026] Among them, four-fifths of the interior of the regulator storage tank 5 is filled with powdered mineral salt regulator 9 and then compacted, and a one-fifth movable gap is reserved at the upper end of the regulator storage tank 5 to facilitate the penetration of the cross bar 8. At the same time, the upper and lower displacement space of the mesh slow-release cover 6 is reserved to form a water inlet channel at the upper port, so that water can enter from the upper port of the mesh slow-release cover 6 and contact with the mineral salt regulator 9 to improve the slow-release efficiency.

[0027] The upward buoyancy of the airbag 2 is consistent with the downward gravitational force exerted by the regulator tank 5, the mesh slow-release cover 6, and the mineral salt regulator 9. The mineral salt regulator 9 in the regulator tank 5 slowly decreases upon contact with water. The crossbar 8, under the weight of the mesh slow-release cover 6, constantly compresses the mineral salt regulator 9 downward, increasing the exposed area of ​​the regulator tank 5 and accelerating the rapid release of various substances into the water as the water flow is disturbed.

[0028] Method of using the above-mentioned mineral slow-release device:

[0029] See Figure 4 , slowly release, put the mineral slow-release device directly into the water, and the water enters from the holes on the surface of the mesh slow-release cover 6 and the hollow chute 10 with the wind and waves, and the mineral salt regulator 9 falls into the water under the action of wind and waves. The minerals in the mineral salt regulator 9 that fall into the water slowly dissolve in the water, thereby achieving the purpose of improving the water quality of aquaculture water.

[0030] See Figure 5, speed up the release, manually rotate the mesh slow-release cover 6 to separate it from the base 1 and then throw it directly into the water. During the process of rotating and separating the mesh slow-release cover 6 and the base 1, since the cross bar 8 is inserted into the inside of the regulator storage tank 5, the regulator storage tank 5 rotates synchronously with the connecting shaft 4 that is movably connected at the top as the axis to avoid rotation obstruction. Since the mesh slow-release cover 6 and the base 1 remain separated, the upper port of the mesh slow-release cover 6 forms a water inlet channel, which increases the number of external channels and speeds up the release compared to the slow release method. With the release of the mineral salt regulator, the mesh slow-release cover 6 is displaced downward by gravity, so that the water inlet channel at the upper port of the mesh slow-release cover 6 is further expanded, and the influence of water flow disturbance will also increase accordingly. At the same time, the water inlet channel and the holes on the surface can form convection, and the release efficiency of the mineral salt regulator is improved.

[0031] In addition, since the upward buoyancy of the airbag 2 is consistent with the overall downward gravity, the release device is initially suspended in the water. With the gradual release of the mineral salt regulator 9, the overall gravity decreases and the buoyancy balance is broken. The airbag 2 can then drive the entire body to move slowly upward, slowly releasing the mineral salt regulator 9 from bottom to top; when the mineral salt regulator 9 is completely released, it will float on the water surface for recovery.
