Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, specifically a modular aquaculture pond base. Background Technology

[0002] The base of an aquaculture pond is the basic supporting structure of the aquaculture pond. Located at the bottom of the pond, it mainly serves to support the weight of the pond and water, maintain the stability of the pond, and optimize the aquaculture environment. The modular aquaculture pond base is a basic structure for supporting the aquaculture pond, which is composed of multiple prefabricated modules. The modules are prefabricated in the factory and then transported to the site for assembly. This eliminates the need for lengthy formwork, pouring, and curing work, shortening the construction cycle and improving construction efficiency.

[0003] The existing technology has the following problems:

[0004] Chinese patent CN118383318 discloses a movable, hydrophobic, heat-insulating modular aquaculture pond base, composed of N modules, where N is greater than or equal to 3; the N modules have the same structure but different sizes; the Nth module is fitted over the (N-1)th module, the (N-1)th module is fitted over the (N-2)th module, and so on, assembling into a cylindrical base; the N modules are arranged coaxially; the innermost first module has a through hole in its center; the bottoms of the N modules are on the same plane; the tops of the N modules maintain a taper of 1-90 degrees, and the tops of the N modules form a straight line; the gaps between adjacent modules are filled with cement mortar.

[0005] While the aforementioned devices can improve installation speed and reduce construction costs, and also have water-repellent, waterproof, heat-insulating, and thermal insulation functions, reducing the energy consumption of traditional aquaculture ponds for constant temperature, the installation process requires pre-arranging the entire structure using a frame and filling the gaps. The installation steps are cumbersome and the positioning is inaccurate, resulting in the inability to maintain a neat arrangement and low assembly efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a modular aquaculture pond base that solves the problem of inaccurate positioning.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: A modular aquaculture pond base includes several modular bases, which are assembled circumferentially to form a cylinder. The cross-section of the modular base is fan-shaped, and the outer arc surface and inner arc surface of the modular base are the outer and inner circumferential surfaces of the base, respectively. The upper surface of the assembled modular base is an inverted cone shape and is covered with a sealant.

[0008] Preferably, the module base includes a base body, a permanent magnet is fixedly connected to the right end of the base body, a locking groove is opened in the middle of the left end of the base body, a rubber gasket is fixedly connected to the outer side of the left end of the base body, a connecting outer groove plate is fixedly connected to the outer circumferential surface of the base body, and two wedge-shaped protrusions are fixedly connected to the bottom end of the base body near the inner circumferential surface.

[0009] Preferably, the engaging groove includes a mortise groove formed at the left end of the base body, two elastic locking blocks are fixedly connected to the bottom inner side of the mortise groove, and a soft magnetic strip is fixedly connected to the top inner side of the mortise groove.

[0010] Preferably, the bottom end of the permanent magnet has two slots for accommodating elastic blocks, and the elastic blocks are made of rubber.

[0011] Preferably, the connecting outer groove plate includes a connecting plate fixedly connected to the lower side of the outer peripheral surface of the base body, a rubber pad fixedly connected to the outer peripheral surface of the base body, and two wedge-shaped grooves that can enter the wedge-shaped protrusions are opened at the top of the connecting plate.

[0012] Preferably, the cross-section of the wedge-shaped protrusion is a right triangle, and the bottom end of the connecting plate after being mortised and connected to the adjacent wedge-shaped protrusion on the outside is on the same plane as the bottom end of the base body.

[0013] This utility model provides a modular base. Compared with the prior art, it has the following advantages:

[0014] 1. This modular aquaculture pond base achieves automatic module positioning through the magnetic attraction of permanent magnets and soft magnetic strips. It eliminates the need for precise module alignment; simply bringing the modules close together allows for automatic alignment under magnetic force, reducing adjustment time during assembly and improving efficiency. Furthermore, the mechanical locking mechanism of the elastic blocks ensures the module's positional accuracy after assembly, preventing module displacement due to weak connections and making the entire cylindrical base structure more stable.

[0015] 2. This modular aquaculture pond base, through the tight fit of wedge-shaped protrusions and wedge-shaped grooves and the elastic sealing effect of rubber pads, forms multiple waterproof barriers, effectively preventing water from seeping into the base from the module joints. This not only improves the waterproof performance of the base, but also, under pressure, the wedge-shaped protrusions move towards the bottom of the wedge-shaped grooves, generating a component force perpendicular to the module surface, making the surfaces of adjacent modules fit tightly together. The tight connection also enhances the overall sealing of the base, enabling the base to maintain structural stability when subjected to water pressure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a modular aquaculture pond base, comprising several modular bases 1, which are assembled circumferentially to form a cylinder. The cross-section of each modular base 1 is fan-shaped, and the outer arc surface and inner arc surface of each modular base 1 are the outer and inner circumferential surfaces of the base, respectively. After the modular bases 1 are assembled, the upper surface is an inverted cone shape and is covered and filled with a sealant 2. After assembly, the upper surface of the base is an inverted cone shape, and the upper surface of the inverted cone shape is covered and filled with a sealant 2 to ensure the sealing of the upper surface of the base and the stability of the overall structure, thus providing a reliable foundation support for the aquaculture pond.

[0024] The sealant 2 is a mixture of several components, including cement mortar and epoxy resin, which has a sealing function. This is existing technology and will not be explained here.

[0025] Please see Figure 2The module base 1 includes a base body 14, a permanent magnet 16 is fixedly connected to the right end of the base body 14, a locking groove 12 is opened in the middle of the left end of the base body 14, a rubber gasket 13 is fixedly connected to the outer side of the left end of the base body 14, a connecting outer groove plate 11 is fixedly connected to the outer circumferential surface of the base body 14, and two wedge-shaped protrusions 15 are fixedly connected to the bottom end of the base body 14 near the inner circumferential surface.

[0026] During assembly, the permanent magnet 16 and the locking groove 12 are used to achieve positioning and locking. The connecting outer groove plate 11 and the wedge-shaped protrusion 15 are positioned and reinforced during installation to enhance the stability of the base. The rubber gasket 13 plays a preliminary sealing role at the gaps of the module splicing to reduce the possibility of moisture penetration.

[0027] Please see Figure 3 The locking groove 12 includes a locking groove 122 opened at the left end of the base body 14. Two elastic locking blocks 123 are fixedly connected to the bottom inner side of the locking groove 122, and a soft magnetic strip 121 is fixedly connected to the top inner side of the locking groove 122.

[0028] Please see Figure 3 The permanent magnet 16 has two slots at its bottom that are designed to accommodate elastic blocks 123. The elastic blocks 123 are made of rubber.

[0029] When the permanent magnet 16 on the right end of one module base 1 approaches the engaging groove 12 on the left end of another module base 1, a magnetic attraction is generated between the soft magnetic strip 121 and the permanent magnet 16, enabling the two modules to automatically align and initially position themselves. As the permanent magnet 16 is further inserted into the engaging groove 122, the elastic locking block 123 is compressed and deformed. When the permanent magnet 16 reaches the appropriate position, the elastic locking block 123 returns to its original shape and engages in the slot at the bottom of the permanent magnet 16, thereby achieving mechanical locking of the two modules, ensuring the positional accuracy of the modules after splicing, and avoiding displacement problems due to insecure connection.

[0030] Please see Figure 4 The connecting outer groove plate 11 includes a connecting plate 111 fixedly connected to the lower side of the outer peripheral surface of the base body 14. A rubber pad 113 is fixedly connected to the outer peripheral surface of the base body 14. Two wedge-shaped grooves 112 are opened at the top of the connecting plate 111 so that the wedge-shaped protrusions 15 can enter.

[0031] Please see Figure 5 The cross-section of the wedge-shaped protrusion 15 is a right triangle. After the connecting plate 111 is connected to the adjacent wedge-shaped protrusion 15 on the outside, the bottom end is on the same plane as the bottom end of the base body 14.

[0032] The wedge-shaped protrusion 15 of another module base 1 is aligned with the wedge-shaped groove 112 at the top of the connecting plate 111 and inserted therein. As the insertion proceeds, the wedge-shaped protrusion 15 and the inclined surface of the wedge-shaped groove 112 fit tightly together to achieve a mortise and tenon connection. The rubber pad 113 is located between the two module bases 1. It is squeezed during the splicing process to fill the gap between the modules. It uses its elasticity to form a sealing barrier to effectively prevent moisture from seeping into the interior of the base from the connection point on the outer periphery of the module.

[0033] Please see Figures 1-5 At work,

[0034] The module base 1 is spliced ​​circumferentially so that the permanent magnet 16 at the right end of one module base 1 is close to the locking groove 12 at the left end of the adjacent module. The magnetic attraction between the soft magnetic strip 121 and the permanent magnet 16 is used to automatically align and position them. The permanent magnet 16 is inserted into the locking groove 122. The elastic rubber block 123 is deformed under pressure and then inserted into the bottom groove of the permanent magnet 16 to achieve mechanical locking. Then, the wedge-shaped protrusion 15 is aligned with the wedge-shaped groove 112 at the top of the adjacent connecting plate 111 from the inside out and inserted to complete the locking connection. At the same time, the rubber pad 113 fills the gap to form a seal. The inverted conical upper surface is covered with a sealant 2 to ensure sealing and stability.
