Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture facilities, specifically a net cage for snakehead fish farming that prevents jumping and escape. Background Technology
[0002] Snakehead fish, also known as blackfish, is a freshwater carnivorous fish with high economic value. It is ferocious by nature, adept at jumping, and possesses strong striking power. In cage aquaculture, snakehead fish are prone to leaping out of the water when disturbed or hunting, leading to injuries, death, or escape, causing significant economic losses to fish farmers.
[0003] Currently, traditional aquaculture cages typically have a protective netting installed on top of the cage. This protective netting is achieved by connecting a support frame to the reinforced edges of the cage.
[0004] However, the existing technical solutions have the following drawbacks in operation: (1) The rigid design of the fixed structure cannot be adapted to the reinforcing edge with different cross-sectional shapes and sizes, resulting in a support frame that can only be applied to barrels of specific specifications, with extremely poor versatility; (2) Its connection point lacks an effective anti-loosening locking mechanism. Under the vibration environment of long-term water flow impact and fish collision, it is easy to loosen or even break apart, posing a risk of escape and requiring frequent maintenance. Utility Model Content
[0005] This utility model aims to provide a net cage for snakehead aquaculture that prevents jumping and escape. It is mainly used to solve the technical problem that the fixed structure design of the existing technology is rigid and cannot be adapted to the reinforcing edges with different cross-sectional shapes and sizes, resulting in a support frame that can only be applied to a specific size of bucket and has extremely poor versatility.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A fishpond for snakehead aquaculture, comprising a cage body and a reinforcing edge on the cage body, the reinforcing edge being located above the cage body and integrally formed with the cage body, the reinforcing edge having a plurality of support frames arranged in a circular array, the support frames being covered with the same protective net, the reinforcing edge having a plurality of sets of mounting supports, the mounting supports including clamping components and limiting components, the support frames being connected to the reinforcing edge through corresponding mounting supports.
[0007] The working principle and beneficial effects of this utility model: 1. Working Principle: The core working principle of this patented solution is to use an integrated installation support system to securely install the arc-shaped support frame on the reinforced edge of the net cage. Multiple support frames above the net cage form a dome-shaped support structure, collectively covering a protective net to form the main escape barrier. Its innovation lies in the installation support employing a rapid installation mechanism that integrates clamping fixation and mechanical self-locking. This mechanism first drives the V-shaped clamping block to firmly clamp onto the reinforced edge through a screwing operation to obtain a stable support foundation; subsequently, the internal limiting mechanism automatically locks key transmission components under the action of springs, effectively preventing loosening caused by vibration or impact, thereby ensuring the long-term stability and reliability of the entire protective net structure, ultimately achieving the goal of effectively preventing snakehead fish from jumping and escaping.
[0008] 2. Beneficial effects: The support frame fixing structure with technical solutions has the following defects during operation: (1) The existing technology solves the technical problem of providing basic support by setting a single type of rigid connector to achieve a fixed connection between the support frame and the reinforcing edge. However, the existing rigid connector cannot adapt to reinforcing edges with different cross-sectional shapes (such as square tubes or round tubes) and sizes, resulting in a support frame that can only match one type of barrel, with extremely poor versatility. In this solution, two V-shaped clamping blocks driven by double-headed screws and capable of moving synchronously in opposite directions are used in the clamping assembly. By adjusting the screws, the opening and clamping force between the two clamping blocks can be changed, so that they can be perfectly adapted and firmly clamped on reinforcing edges of different shapes and sizes, thereby solving the technical problem that the support frame cannot be universally installed on barrels of different specifications.
[0009] (2) In this solution, a limiting block is set in the limiting component, which is automatically pressed into the limiting groove by a compression spring. After the handle is rotated to adjust and clamp, the mechanism can automatically lock the double-ended lead screw to prevent it from reversing due to vibration or external impact, thus solving the technical problem that the existing bracket is easy to loosen after connection and requires frequent maintenance and fastening.
[0010] Preferably, the clamping assembly includes a base plate located above the reinforcing edge. The base plate is inclined, and two support plates are fixedly connected to the side of the base plate near the reinforcing edge. A double-ended lead screw is rotatably connected to the two support plates. A guide groove is formed on the side of the base plate near the support plates. Two first sliders are slidably connected to the double-ended lead screw. The two first sliders are located in the same guide groove and are slidably connected to the inner wall of the same guide groove. A connecting block is fixedly connected to the side of the first slider away from the base plate. Clamping blocks are fixedly connected to the opposite sides of the two connecting blocks. By rotating the double-ended lead screw, the two first sliders can be driven to move towards or away from each other, thereby clamping or releasing the reinforcing edge with the two clamping blocks. The operation is simple and the fixation is firm.
[0011] Preferably, the limiting component includes a handle located on one side of the double-ended lead screw. The handle is fixedly connected to the bottom end of the double-ended lead screw. Several limiting grooves arranged in a circular array are formed on the periphery of the handle. A fixing block is fixedly connected to one end of the base plate near the handle. A sliding groove is formed on the fixing block, which passes through the bottom end of the fixing block and communicates with the outside. A second slider is slidably connected in the sliding groove. A limiting block is fixedly connected to the bottom end of the second slider. The limiting block is inserted into the corresponding limiting groove. When the handle is rotated to a suitable position to clamp the reinforcing edge with the clamping block, the limiting block is inserted into the corresponding limiting groove under the action of the elastic element, thereby effectively preventing the double-ended lead screw from reversing due to vibration or other reasons and ensuring the stability of the clamping state.
[0012] Preferably, a compression spring is provided inside the fixing block. One end of the compression spring is fixedly connected to the inner wall of the slide groove, and the other end of the compression spring is fixedly connected to the top of the second slider. The compression spring provides continuous downward pressure to the limiting block to ensure that it can automatically engage in the limiting groove.
[0013] Preferably, the support frame has an installation groove at one end near the base plate, and an installation block is fixedly connected to the side of the base plate near the support frame. The installation groove engages with the corresponding installation block. During installation, the installation groove engages with the corresponding installation block. This design serves as initial positioning and load-bearing, preventing the support frame from sliding down in the vertical direction and transferring most of the weight to the reinforcing edge through the base plate. The clamping assembly provides the main locking force to fix the entire support to the reinforcing edge. The two work together to make the connection more stable and reliable.
[0014] Preferably, the clamping block is V-shaped, and two rubber pads are fixedly connected to the inner wall of the clamping block. The V-shaped structure can better adapt to the common shape of the reinforcing edge of the cage (such as square tube or round tube), increasing the contact area, while the anti-slip rubber pads further enhance the friction, prevent slippage, and avoid the clamping block causing hard scratches to the surface of the reinforcing edge.

[0017] 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.
[0018] like Figure 1 - Figure 6 As shown, a snail farming anti-jumping and anti-escape net cage includes a cage body 1 and a reinforcing edge 2 set on the cage body 1. The reinforcing edge 2 is located above the cage body 1 and is integrally formed with the cage body 1. Several support frames 3 are arranged in a circular array on the reinforcing edge 2. The same protective net 4 is covered on the several support frames 3. Several sets of mounting supports are set on the reinforcing edge 2. The mounting supports include clamping components and limiting components. The support frames 3 are connected to the reinforcing edge 2 through corresponding mounting supports. This structure improves the overall structural strength of the cage body 1 through the integrally formed reinforcing edge 2. The circular array of support frames 3 provides uniform support for the protective net 4, effectively preventing the net cage from deforming or being damaged by the snail jumping and impacting. The mounting supports adopt a dual fixing method of clamping and limiting to ensure that the support frames 3 are installed stably and avoid displacement due to fish impact or water flow, thereby improving the reliability of anti-escape.
[0019] More specifically, the clamping assembly includes a base plate 5, which is located above the reinforcing edge 2. The base plate 5 is inclined, and two support plates 6 are fixedly connected to the side of the base plate 5 near the reinforcing edge 2. The same double-ended lead screw 7 is rotatably connected to the two support plates 6. A guide groove 8 is provided on the side of the base plate 5 near the support plates 6. Two first sliders 9 are slidably connected to the double-ended lead screw 7. The two first sliders 9 are located in the same guide groove 8 and are slidably connected to the inner wall of the same guide groove 8. A connecting block 10 is fixedly connected to the side of the first slider 9 away from the base plate 5. Clamping blocks 11 are fixedly connected to the opposite sides of the two connecting blocks 10. When the double-ended lead screw 7 rotates, it drives the two first sliders 9 to move synchronously in opposite directions along the guide groove 8. The connecting blocks 10 drive the two V-shaped clamping blocks 11 to clamp or release the reinforcing edge 2. This design uses lead screw transmission to achieve a stable and reliable clamping force. The guide groove 8 ensures that the slider movement trajectory is accurate and avoids deflection, making the clamping action smooth and applying uniform pressure to the reinforcing edge 2.
[0020] More specifically, the limiting component includes a handle 13, which is located on one side of the double-ended lead screw 7. The handle 13 is fixedly connected to the bottom end of the double-ended lead screw 7. Several limiting grooves 14 arranged in a circular array are provided on the periphery of the handle 13. A fixing block 15 is fixedly connected to one end of the base plate 5 near the handle 13. A sliding groove 16 is provided on the fixing block 15. The sliding groove 16 passes through the bottom end of the fixing block 15 and communicates with the outside. A second slider 17 is slidably connected in the sliding groove 16. A limiting block 18 is fixedly connected to the bottom end of the second slider 17. The limiting block 18 is inserted into the corresponding limiting groove 14. The clamping state can be quickly adjusted by rotating the double-ended lead screw 7 by rotating the handle 13. The insertion and cooperation of the limiting groove 14 and the limiting block 18 realizes the position locking, preventing the double-ended lead screw 7 from loosening due to vibration or accidental rotation by external force. The structure of the sliding groove 16 allows the limiting block 18 to move vertically to adapt to the limiting groove 14 at different angles, ensuring flexible and reliable locking and improving the long-term stability of the clamping component.
[0021] More specifically, a compression spring 19 is provided inside the fixing block 15. One end of the compression spring 19 is fixedly connected to the inner wall of the slide groove 16, and the other end of the compression spring 19 is fixedly connected to the top of the second slider 17. The compression spring 19 always pushes the second slider 17 and the limiting block 18 downward, so that the limiting block 18 automatically embeds into the limiting groove 14 on the handle 13 to achieve a self-locking function. This design can maintain the locked state without additional operation, reducing the need for manual intervention. At the same time, the spring buffering effect reduces mechanical wear and extends the service life of the limiting component.
[0022] More specifically, the support frame 3 has an installation groove 20 at one end near the base plate 5, and an installation block 21 is fixedly connected to the side of the base plate 5 near the support frame 3. The installation groove 20 and the corresponding installation block 21 are engaged. The engagement between the installation groove 20 and the installation block 21 enables the support frame 3 and the base plate 5 to be quickly connected, simplifying the installation and disassembly process. This structure ensures the connection strength while facilitating the maintenance or replacement of local components, improving the modularity and ease of use of the cage.
[0023] More specifically, the clamping block 11 is V-shaped, and two rubber pads 12 are fixedly connected to the inner wall of the clamping block 11. The V-shaped clamping block 11 can adapt to the contour of the reinforcing edge 2, increase the contact area and disperse the pressure, and avoid local stress concentration that could damage the reinforcing edge 2. The rubber pads 12 are made of anti-slip and wear-resistant material, which further enhances the clamping friction and protects the surface of the reinforcing edge 2, preventing slippage or scratches, and ensuring that the clamping is firm and does not damage the cage structure.
[0024] As can be seen from the above, the specific embodiments of this utility model are as follows: The working principle of this cage begins with its core structure: the support frame 3 is securely installed on the reinforcing edge 2 of the cage body 1 via mounting brackets. During installation, the operator first aligns the mounting block 21 on the base plate 5 and inserts it into the mounting groove 20 at the bottom of the support frame 3, completing the initial quick connection between the support frame 3 and the clamping assembly. Next, the operator drives the double-ended screw 7 to rotate by turning the handle 13. The rotation of the double-ended screw 7 causes the two first sliders 9, which are threaded together, to slide synchronously towards each other under the constraint of the guide groove 8. The movement of the first sliders 9 is transmitted to the two V-shaped clamping blocks 11 through the connecting block 10, driving them to close smoothly and powerfully, ultimately clamping them tightly on both sides of the reinforcing edge 2. The V-shaped design and the rubber gasket 12 on the inner wall ensure full contact between the clamping surface and the reinforcing edge 2, providing great friction and preventing slippage and scratches. The entire support frame 3 and the protective net 4 above it are stably fixed to the housing 1. After the clamping block 11 is clamped in place, the limiting component begins to play a key role. Under the continuous downward elastic force of the compression spring 19, the second slider 17 drives the limiting block 18 at its bottom end to move naturally downward in the slide groove 16 of the fixed block 15. The lower end of the limiting block 18 is then embedded into the limiting groove 14 corresponding to the current handle 13. This action is like an automatic latch, which firmly locks the handle 13 and the double-ended lead screw 7 fixedly connected to it, effectively preventing the lead screw from accidentally reversing due to water fluctuations, fish collisions or vibrations, thereby eliminating the risk of clamping loosening. Finally, all the support frames 3 are installed in a circular array on the reinforcing edge 2 in this way, together supporting the protective net 4 covering it. The entire system forms a solid and reliable protective barrier.
[0025] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
