Description

Technical Field

[0001] This utility model belongs to the field of aquaculture box technology, specifically relating to a prefabricated aquaculture box. Background Technology

[0002] In aquaculture, live seafood holding, and seedling cultivation, aquaculture tanks serve as core water storage and aquaculture containers. Their size compatibility and assembly efficiency directly impact aquaculture costs, site utilization, and operational flexibility. Currently, the aquaculture tanks widely used in the industry are mainly divided into two categories: integral rigid aquaculture tanks and simple canvas aquaculture tanks. However, both types of products have the following technical problems in practical applications: The body and supporting structure of integrated rigid aquaculture cages are mostly manufactured as a single piece in the factory, with fixed specifications such as height and diameter, making it impossible to flexibly adjust them according to the needs of different aquaculture scenarios. In addition, the integrated structure is bulky, requiring oversized vehicles for transportation, which is especially problematic for small farms in remote areas, resulting in high transportation costs and an inability to flexibly adjust the layout according to the size of the site. Although simple canvas aquaculture boxes use flexible canvas bodies and can theoretically be adapted to different sites, their support structure design has obvious flaws. Existing simple canvas aquaculture boxes are mostly supported by either "fixed-length welded steel pipe frames" or "rope binding and fixing": the former is similar to integral rigid aquaculture boxes, with fixed frame specifications and no adjustment of height or diameter; the latter, although it can be roughly adjusted by tightening the ropes, has extremely poor support stability, and after being filled with water, the canvas box is prone to deformation and collapse due to water pressure. Currently, there is no technical solution in the industry that can simultaneously solve the problems of flexible specification adjustment and rapid assembly: although the integral rigid breeding box has a stable structure, it has poor adaptability and is inconvenient to transport; although the simple canvas breeding box has a certain degree of flexibility, its support structure is fixed or its assembly is cumbersome. In summary, the technical deficiencies of existing aquaculture tanks in terms of size adaptability and assembly efficiency restrict the flexibility and economy of aquaculture scenarios. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a prefabricated aquaculture tank that solves the technical deficiencies of existing aquaculture tanks in terms of specification adaptability and assembly efficiency, which restrict the flexibility and economy of aquaculture scenarios.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated aquaculture tank, comprising a support frame and a PVC coated canvas water tank. The support frame is supported on the outside of the PVC coated canvas water tank, and the top of the PVC coated canvas water tank is attached to the top of the support frame. The support frame is a closed frame structure composed of multiple uprights and crossbars. The uprights include multiple main rods that are threaded together. The crossbars include cross plates, and each end of the cross plate is formed with a snap-fit ​​connector 1 and a snap-fit ​​connector 2. The snap-fit ​​connector 1 and snap-fit ​​connector 2 are staggered vertically. The snap-fit ​​connector 1 and snap-fit ​​connector 2 in two adjacent crossbars are arranged facing each other and elastically snapped onto the same main rod.

[0005] The beneficial effects of this utility model are as follows: by connecting different numbers of cross frames and main poles, support frames of different diameters and heights can be assembled to support PVC coated canvas water tanks of corresponding specifications, effectively improving the applicability of the device; the cross frames and main poles are quickly and stably connected by elastic snap-fit ​​and threaded connection, effectively improving the efficiency of loading and unloading the support frame.

[0006] To facilitate easy interlocking between the crossbar and the upright; As a further improvement to the above technical solution: both the first and second snap-fit ​​connectors are composed of an elastic plate and an arc-shaped plate. The two ends of the elastic plate are respectively connected to a horizontal plate and an arc-shaped plate, and there are two elastic plates that are spaced apart from each other. The axes of the arc-shaped plates installed on the two elastic plates are collinear.

[0007] The beneficial effects of this improvement are as follows: the opening ends of both snap-fit ​​connector one and snap-fit ​​connector two are slightly smaller than the diameter of the screw in the main rod body, which can generate elastic deformation when squeezed and expand outward to snap onto the outside of the screw, thereby realizing the quick connection between the cross frame and the column.

[0008] To facilitate easy adjustment of the main pole to a suitable support height; As a further improvement to the above technical solution: the main rod body is composed of multiple support tubes, the top end of the support tube is welded with a screw, and the bottom end of the support tube is provided with an internal thread structure for threaded connection of the screw.

[0009] The beneficial effect of this improvement is that multiple support tubes can be conveniently and securely connected by screws to assemble a main pole of suitable height for use.

[0010] To ensure a stable connection between the crossbar and the upright; As a further improvement to the above technical solution: the second clamping connector is located on the upper and lower sides of the first clamping connector, and the height of the screw minus the height of the internal thread at the bottom of the support tube is equal to the height of the second clamping connector.

[0011] The beneficial effect of this improvement is that after multiple support pipes are connected by screws, the second clamp can be fitted onto the screws exposed between adjacent support pipes, thus avoiding displacement in the axial direction of the column.

[0012] In order to effectively improve the structural strength of the crossbeam; As a further improvement to the above technical solution: the side of the horizontal plate facing away from the PVC coated canvas water tank is formed with reinforcing ribs.

[0013] The beneficial effects of this improvement are: the protruding reinforcing ribs can effectively improve the structural strength of the horizontal plate.

[0014] To ensure that the bolts in each column are at the same height for easy connection of the cross frame; As a further improvement to the above technical solution: the bottom end of the main rod is threadedly connected to a foot, which consists of a screw threadedly connected to a support tube and a plate welded to the bottom end of the screw.

[0015] The beneficial effects of this improvement are: by rotating the base feet to adjust their position on the main body, the screws in each column are at the same height when the ground where the breeding box is placed is slightly uneven, so as to facilitate and stably connect multiple cross frames.

[0016] To ensure a stable connection between the support frame and the PVC coated canvas water tank; As a further improvement to the above technical solution: the top of the PVC coated canvas water tank is provided with multiple through holes, and the ropes passing through the through holes are tied to the top of the supporting frame.

[0017] The beneficial effect of this improvement is that when the PVC coated canvas water tank is supported by the outer support frame, its top is connected to the top of the support frame in a tied manner, thus preventing the top from collapsing.

[0018] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0021] Example 1: As Figure 1As shown in Figure 6: A prefabricated aquaculture tank includes a support frame 100 and a PVC-coated canvas water tank 200. The support frame 100 is supported on the outside of the PVC-coated canvas water tank 200, and the top of the PVC-coated canvas water tank 200 is attached to the top of the support frame 100. The support frame 100 is a closed frame structure composed of multiple uprights 1 and crossbars 2. The uprights 1 include multiple main rods 11 that are threaded together. The crossbars 2 include cross plates 21. The two ends of the plate 21 are respectively formed with a snap-fit ​​connector 1 23 and a snap-fit ​​connector 24. The snap-fit ​​connector 1 23 and the snap-fit ​​connector 24 are arranged alternately. The snap-fit ​​connector 1 23 and the snap-fit ​​connector 24 in two adjacent crossbars 2 are arranged facing each other and elastically snapped onto the same main rod 11. By connecting different numbers of crossbars 2 and main rods 11, support frames 100 of different diameters and heights can be assembled to support PVC coated canvas water tanks 200 of corresponding specifications, effectively improving the applicability of the device.The crossbeam 2 and the main rod 11 are quickly and securely connected via elastic snap-fit ​​and threaded connections, effectively improving the efficiency of assembling and disassembling the support frame 100. Both snap-fit ​​connector 1 23 and snap-fit ​​connector 24 are composed of elastic plates 231 and arc-shaped plates 232. The two ends of the elastic plates 231 are connected to the crossbeam 21 and the arc-shaped plates 232, respectively. There are two elastic plates 231, spaced apart from each other. The axes of the arc-shaped plates 232 mounted on the two elastic plates 231 are collinear. The openings of both snap-fit ​​connector 1 23 and snap-fit ​​connector 24 are slightly smaller than the screw 14 in the main rod 11. The diameter, which can elastically deform and expand outward under compression, is clamped onto the outside of the screw 14, thereby realizing a quick connection between the cross frame 2 and the column 1. The main rod body 11 is composed of multiple support tubes 13. The top end of each support tube 13 is welded with a screw 14, and the bottom end of each support tube 13 has an internal thread structure for threaded connection to the screw 14. Multiple support tubes 13 can be conveniently and securely connected by the screw 14 to assemble a main rod body 11 of suitable height for use. The second clamping connector 24 is located on the upper and lower sides of the first clamping connector 23. The height of the screw 14 minus the height of the bottom of the support tube 13 is... The height of the internal thread is equal to the height of the snap-fit ​​connector 24. After multiple support pipes 13 are connected by screws 14, the snap-fit ​​connector 24 can be fitted onto the screws 14 exposed between adjacent support pipes 13 to prevent displacement in the axial direction of the column 1. The horizontal plate 21 has a reinforcing rib 22 protruding from the side facing away from the PVC coated canvas water tank 200. The protruding reinforcing rib 22 can effectively improve the structural strength of the horizontal plate 21. The bottom end of the main rod 11 is threadedly connected to a foot 12. The foot 12 consists of a screw threaded to the support pipe 13 and welded to the screw. The bottom plate is composed of a base foot 12. The position of the base foot 12 on the main rod 11 can be adjusted by rotating the base foot 12, ensuring that the screws 14 in each column 1 are at the same height even on slightly uneven ground. This facilitates convenient and stable connection of multiple crossbars 2. The top of the PVC-coated canvas water tank 200 has multiple through-holes, and ropes threaded through these holes are tied to the top of the support frame 100. When the PVC-coated canvas water tank 200 is supported by the outer support frame 100, its top is connected to the top of the support frame 100 in a tied manner to prevent the top from collapsing.

[0022] The working principle of this technical solution is as follows: Determine the target height of the column, select the corresponding number of support tubes 13, screw the screw 14 at the top of one support tube 13 into the internal thread structure at the bottom of another support tube 13, and rotate clockwise until they fit tightly to complete the assembly of the main rod body 11; thread the base 12 at the bottom of the main rod body 11, and adjust the extension length of the base by rotating the flat part of the base 12. After all the columns 1 are assembled, place them evenly in the preset position and stand them upright. Check the height of the screw 14 at the top of each column, and make fine adjustments to the base 12 to ensure that the height of the screws at the top of all columns is consistent, so as to provide a flat reference for the connection of the cross frame 2. Based on the target diameter, select the corresponding number of crossbeams 2. Take the first crossbeam 2 and align one end of its snap-fit ​​connector 23 with the screw rod 14 of a column. The bottom of the opening of the arc plate 232 should be on the screw rod 14. Press the crossbeam 2 firmly to expand the opening of the arc plate 232 and cause the elastic plate 231 to move outward, generating elastic deformation. At this time, the inner width of the opening end of the arc plate 232 increases to be greater than the diameter of the screw rod 14, so that the two arc plates 232 are fitted onto the screw rod 14. After releasing, the elastic plate 231 returns to its original position. The arc-shaped plate 232 is tightly attached to the screw 14 to achieve fixation; take the second cross frame, align the second snap-fit ​​connector 24 at one end of it with the screw 14 of the same column, and repeat the operation of pressing the elastic plate so that the second snap-fit ​​connector 24 and the first snap-fit ​​connector 23 are staggered and snapped onto the same screw 14, thus completing the splicing of the two cross frames 2; in the above method, the remaining cross frames 2 are sequentially snapped onto the screws of the other columns 1 through the first snap-fit ​​connector 23 and the second snap-fit ​​connector 24, finally forming the support frame 100 of the closed frame structure; Lay the PVC coated canvas water tank 200 flat on the ground inside the support frame 100, ensuring that the center of the canvas water tank is aligned with the center of the support frame. Take a rope and pass it through one of the through holes at the top of the PVC coated canvas water tank 200, tie a knot to secure it, and tie the other end of the rope to the crossbar 2 at the top of the support frame 100. Tighten the rope so that the top of the PVC coated canvas water tank 200 is tightly against the support frame 100. Repeat the above method to tie the rope to all the through holes of the canvas water tank in sequence, maintaining an appropriate distance between adjacent through holes to ensure that the top of the canvas is evenly stressed. Finally, the PVC coated canvas water tank 200 is fully unfolded, with its outer side tightly against the support frame 100, forming a closed water storage space.
