Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a multi-layer elevated aquaculture pond device. Background Technology

[0002] Traditional single-layer fishponds are mostly independent ponds with a flat layout, usually built directly on the ground or on a simple raised foundation. Their structure is relatively simple, relying mainly on the pond's own materials and the foundation's load-bearing capacity. This single-layer design has significant drawbacks in areas with limited land resources, such as coastal mudflats and mountainous slopes: firstly, due to the limited floor space, the aquaculture volume is directly linked to the land area, resulting in extremely low land utilization and making it difficult to expand aquaculture scale on limited land; secondly, in areas with complex terrain, large-scale land leveling is often required for construction, which not only increases construction costs but may also damage the local ecological environment, making it less adaptable. Utility Model Content

[0005] Preferably, the bolts are fixed in such a way that the bottom layer aquaculture tank unit is fixed with no less than four rows of bolts; the middle layer aquaculture tank unit uses fewer rows of bolts than the bottom layer; the top layer aquaculture tank unit uses fewer rows of bolts than the middle layer; and the bolt holes of each layer aquaculture tank unit are non-collinearly distributed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a multi-layer high-level aquaculture pond device, which solves the key bottleneck of high-level pond aquaculture through a multi-layer composite structure. The vertical stacking design breaks through the limitations of planar aquaculture. Under the same land area, the multi-layer layout increases the aquaculture volume, and the land utilization rate is many times that of traditional single-layer ponds. It is especially suitable for restricted areas such as coastal or mountainous areas.

[0018] The following is in conjunction with the appendix Figures 1-4To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art to which this utility model pertains.

The drawings in this utility model are not strictly drawn to scale; the specific dimensions and quantity of each structure can be determined according to actual needs. The drawings described in this utility model are only structural schematic diagrams.

[0020] This utility model provides a multi-layer elevated aquaculture pond device, such as... Figures 1-4 As shown, the aquaculture pond unit 1 includes at least two layers of aquaculture pond units stacked from bottom to top. Each aquaculture pond unit 1 consists of an inner layer 101 structure, an outer layer 102 structure, and a filling layer 103. The inner layer 101 structure is a closed water tank made of polypropylene material, the outer layer 102 structure is a support frame formed by corrugated steel plates, and the filling layer 103 is polyurethane foam material filling the gap between the inner layer 101 structure and the outer layer 102 structure. The closed connection of the support frame is fixed by bolts 2, and the number of rows of bolts 2 in the lower aquaculture pond unit 1 is greater than that in the upper aquaculture pond unit 1.

[0021] By using a multi-layered composite structure to collaboratively address the key bottlenecks of high-level pond aquaculture, the vertical stacking design breaks through the limitations of planar aquaculture. With the same land area, the multi-layered layout increases the aquaculture volume, and the land utilization rate is many times that of traditional single-layer ponds. It is especially suitable for restricted areas such as coastal or mountainous regions. Adjacent aquaculture pond units 1 are fixedly connected by staggered bolts 2, and the number of bolts 2 in the lower aquaculture pond unit 1 is more than that in the upper aquaculture pond unit 1, so that the load transfer path is distributed in a tree-like manner, which decomposes the water pressure and forms a composite structure that combines waterproofing, heat preservation and high-strength support, making the whole device more stable.

[0022] The aquaculture pond unit 1 consists of an inner layer 101 made of polypropylene with a molecular-level dense structure to achieve zero permeability, and a filling layer 103 made of polyurethane foam to form a thermal barrier, controlling the water temperature within the aquaculture pond and maintaining a constant temperature. The outer layer 102 is a support frame composed of corrugated steel plates, which utilizes the moment of inertia of the corrugated section to improve bending stiffness, making the aquaculture pond unit 1 more stable as a whole. A filling layer 103 made of polyurethane foam is set between the inner layer 101 and the outer layer 102 to form a thermal barrier, controlling the water temperature within the aquaculture pond unit 1 and maintaining a temperature suitable for fish survival within the aquaculture pond unit 1.

[0023] Preferred, such as Figures 1-2 As shown, the bolts 2 are fixed in the following ways: the bottom layer aquaculture tank unit 1 is fixed with no less than four rows of bolts 2; the middle layer aquaculture tank unit 1 uses fewer rows of bolts 2 than the bottom layer; the top layer aquaculture tank unit 1 uses fewer rows of bolts 2 than the middle layer; and the bolt holes of each layer aquaculture tank unit 1 are non-collinearly distributed.

[0024] In this embodiment, the bottom layer uses 4 rows of bolts 2 to increase the density of fixing points, thereby suppressing the deformation displacement of the bottom aquaculture pond unit 1 within a certain range and enhancing the stability of the bottom aquaculture pond unit 1. The bolt holes of each layer of aquaculture pond unit 1 are non-collinearly distributed, so that the axis of bolt 2 forms an angle with the direction of principal stress, cutting off the propagation path of resonance waves.

[0025] Preferred, such as Figures 1-2 As shown, reinforcing ribs 3 are provided at the welded joints of the inner layer 101 structure, and the reinforcing ribs 3 are distributed in a ring along the height direction of the water tank.

[0026] In this embodiment, a PP reinforcing rib with a cross section of 20×20mm is set on the back side of the weld seam to increase the bending modulus of the weld seam area by increasing the moment of inertia; the ring-closed design of the reinforcing rib 3 forms a continuous constraint, which converts the water pressure load into circumferential compressive stress to avoid creep cracking under pressure at the connection of adjacent aquaculture tank unit 1.

[0027] Preferred, such as Figures 1-2 As shown, the bottom of the lowest aquaculture pond unit 1 is connected to a funnel-shaped diversion pool 5, and the bottom of the diversion pool 5 is equipped with a fish pond drain 6.

[0028] In this embodiment, the fish suction pump achieves non-destructive and efficient harvesting. The fish suction pump includes a pump body and a fish suction pipe 4. The fish suction pipe 4 is fixedly inserted into the funnel-shaped diversion pool 5 and works in conjunction with the fish pond floor drain 6 at the end to reduce the amount of residual water and eliminate the breeding ground for pathogens.

[0029] The diversion pool 5 is designed in a funnel shape to achieve rapid drainage and increase the drainage speed.

[0030] Preferred, such as Figures 1-2 As shown, the corrugated steel sheet of the outer 102 structure is a galvanized steel sheet.

[0031] In this embodiment, the corrugated plate substrate is made of galvanized material to avoid rust, and the joints between the plates are filled with polysulfide sealant to form an elastic sealing layer.

[0032] Preferred, such as Figures 1-2 As shown, the number of stacked layers of aquaculture pond unit 1 is 2-4 layers.

[0033] In this embodiment, ANSYS simulation shows that the space utilization rate is improved when there is 2 layers, but the investment return period is long; when there are 4 layers, the maximum equivalent stress of the lower layer is too large and the pressure of the bottom aquaculture pond unit 1 is too large; the preferred option is a 3-layer scheme: the space utilization rate is suitable, the stress value of the lower layer is within the safety factor, and both economic benefits and safety are taken into account.

[0034] Preferably, an oil sludge collector 7 is provided on the side of the top-level aquaculture tank unit.

[0035] The surface oil collector 7 installed on the side wall of the fishpond primarily functions to efficiently collect and remove oil and floating impurities from the surface of the aquaculture water. This oil may originate from lipids produced by the decomposition of feed residue, metabolic secretions from farmed organisms, or accidentally introduced grease (such as lubricating oil from equipment maintenance). Over time, this oil accumulates, forming a film on the water surface that hinders gas exchange between the water and air, affecting dissolved oxygen levels. Furthermore, the oil and attached impurities can breed harmful microorganisms, disrupting the water quality balance and ultimately impacting the healthy growth of farmed organisms. Timely removal of these substances by the surface oil collector 7 effectively maintains a stable aquatic environment, reduces the risk of disease, and ensures the ecological balance and profitability of the aquaculture system.

[0036] The method of using this multi-layer elevated aquaculture pond device is as follows: Efficient aquaculture is achieved through modular assembly. First, the bottom aquaculture pond unit 1 is fixed on a flat foundation using staggered bolts 2. Then, the middle aquaculture pond unit 1 and the top aquaculture pond unit 1 are stacked layer by layer. The layers are filled with polyurethane foam material to form a heat-insulating and load-bearing structure. During the aquaculture process, a fish suction pump is used for layered feeding and harvesting. When harvesting, the valve is opened to allow the fish-water mixture to flow through the gradient filter screen and finally drain the water quickly through the funnel-shaped diversion pool 5.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
