Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a quick replacement device for abalone attachment substrate. Background Technology

[0002] Abalone attachment substrates play a crucial role in the abalone farming industry. As the core carrier for the attachment, growth, and development of juvenile abalone, their structural stability, cleanliness, and ease of replacement have a decisive impact on the survival rate, growth rate, and farming efficiency of abalone. Especially in the later stages of the farming cycle or during the critical phase of batch rotation, the attachment substrates, due to long-term immersion in seawater, are prone to attracting fouling organisms or undergoing structural aging. Therefore, they must be replaced or cleaned regularly to ensure the water quality and the health of the abalone. However, existing traditional abalone attachment substrate devices mostly adopt fixed frame structures, whose height, spacing, and connection methods are not adjustable after installation. In actual farming operations, a series of obvious limitations and technical problems have gradually been exposed.

[0003] Existing fixed frame attachment devices face prominent problems such as inconvenience, low efficiency, and maintenance difficulties during installation and dismantling in aquaculture ponds. Due to their rigid structure and lack of quick-release mechanisms, replacement often requires multiple people to work together, use tools, or even partially dismantle the pond structure, which is time-consuming and labor-intensive and seriously affects the pace of aquaculture operations. At the same time, the inability to flexibly adjust the layer height or spacing according to different growth stages of abalone results in low space utilization and poor water exchange, further affecting the uniform growth of abalone.

[0004] Therefore, in view of the shortcomings of existing technologies, we urgently need a quick replacement device for abalone attachment substrate to solve this problem. This new device should significantly improve the efficiency and convenience of attachment substrate replacement and maintenance, support highly flexible adjustment and modular quick disassembly, and better meet the specific needs of modern, large-scale abalone farming for efficient operation, clean management and risk control, thus providing strong support for the sustainable development of the aquaculture industry. Utility Model Content

[0005] The purpose of this invention is to provide a quick replacement device for abalone attachment substrates, which solves the prominent problems of inconvenient operation, low efficiency, and difficult maintenance faced by existing fixed frame attachment substrate devices in the aquaculture pond during installation and disassembly. Due to the rigid structure and lack of quick-disassembly mechanism, replacement often requires multiple people to work together, use tools, and even partially disassemble the pond structure, which is time-consuming and labor-intensive, seriously affecting the rhythm of aquaculture operations. At the same time, the inability to flexibly adjust the layer height or spacing according to different growth stages of abalone leads to low space utilization and poor water exchange, further affecting the uniform growth of abalone.

[0006] To achieve the above objectives, this utility model provides a quick replacement device for abalone attachment bases, comprising several mounting plates and several abalone attachment bases disposed on one side of the mounting plates. Support rods are fixedly connected to both sides of the bottom of the mounting plates. The bottom of each abalone attachment base is connected to the top of the two support rods. Two lower locking blocks are connected to one side of each abalone attachment base. Two through slots are formed on one side of the mounting plates. Each through slot contains an upper locking block. The top of each upper locking block is connected to the top of the through slot via an elastic connection structure. The top of each lower locking block has an upper inclined surface, and the bottom of each upper locking block has a lower inclined surface that cooperates with the upper inclined surface.

[0007] The abalone attachment base has placement slots on both sides of its top. Each placement slot has an adjusting plate slidably connected inside, and each placement slot has a horizontal adjusting structure on one side inside that cooperates with the end of the adjusting plate.

[0008] Preferably, the elastic connection structure includes several compression springs and a damper connected together between the upper locking block and the inner wall of the mounting plate, and a pull rod with one end sliding through the top of the mounting plate is connected to the top of the upper locking block.

[0009] Preferably, horizontal grooves are provided on both sides of the inner wall of the placement groove. The horizontal adjustment structure includes a sliding block slidably connected inside the two horizontal grooves, a screw rod with one end threaded through the sliding block and rotatably connected to the inner wall of one of the horizontal grooves, and a guide rod with one end slidably through the sliding block and slidably connected to the inner wall of the other horizontal groove. The two ends of the adjustment plate are respectively connected to the two sliding blocks.

[0010] Preferably, one end of the lead screw is rotatably connected to a rotating disk through the side wall of the mounting plate, and a rotating handle is fixedly connected to one side of the rotating disk.

[0011] Preferably, the rotating handle is made of metal, and the surface of the rotating handle is provided with anti-slip grooves.

[0012] Preferably, a handle is fixedly connected to the top of the pull rod, and the mounting plates are connected to each other by a connecting bracket.

[0013] This utility model discloses a quick-replacement device for abalone attachment substrates. Through the inclined guide cooperation of the lower and upper locking blocks and an elastic reset locking mechanism, it achieves a tool-free quick-release function between the abalone attachment substrate and the mounting plate: "push in and lock, pull out and detach." A single person can complete installation or disassembly within seconds, significantly reducing labor costs and operational barriers, greatly improving work efficiency, and avoiding disruption to the overall aquaculture rhythm due to excessive replacement time. Addressing the problem of "inability to flexibly adjust spacing according to abalone growth stages, leading to uneven space utilization and poor water flow," the device features a placement slot with an adjustment plate and horizontal adjustment structure on the top of the abalone attachment substrate, allowing aquaculture personnel to adjust the spacing according to the different body sizes of juvenile, medium, or adult abalone. Density requirements are addressed by dynamically adjusting the physical spacing or water flow channel width between adjacent individuals to optimize the utilization rate of the attachment surface and the efficiency of water exchange, promoting uniform feeding and healthy growth of abalone, and reducing growth differences and disease risks caused by overcrowding or dead water flow. Addressing the drawbacks of traditional methods such as rigid structures, difficult maintenance, and the need to dismantle the entire tank, this device adopts a modular design concept. The support rods and mounting plates serve as permanent, fixed foundation structures, while the abalone attachment base is an independent, replaceable unit that can be disassembled at any time. This avoids the cumbersome process of dismantling the entire frame or damaging the tank structure, reducing equipment wear and maintenance costs, minimizing interference with the aquaculture environment, and ensuring continuous production.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Example 1

[0022] Please see Figure 1-4 As shown, this embodiment of a quick-change device for abalone attachment base includes several mounting plates 2 and several abalone attachment bases 1 disposed on one side of the mounting plates 2. Support rods 4 are fixedly connected to both sides of the bottom of the mounting plates 2. The bottom of the abalone attachment base 1 is connected to the top of the two support rods 4. Two lower locking blocks 6 are connected to one side of the abalone attachment base 1. Two through slots are opened on one side of the mounting plates 2. Each through slot is provided with an upper locking block 15. The top of the upper locking block 15 is connected to the top of the through slot through an elastic connection structure. The top of the lower locking block 6 is provided with an upper inclined surface, and the bottom of the upper locking block 15 is provided with a lower inclined surface that cooperates with the upper inclined surface.

[0023] The abalone attachment base 1 has placement slots 5 on both sides of its top. Each placement slot 5 has an adjusting plate 16 slidably connected inside. Each placement slot 5 has a horizontal adjusting structure that cooperates with the end of the adjusting plate 16 on one side inside.

[0024] In actual operation, the workflow of this abalone attachment substrate quick replacement device is as follows: First, the operator needs to pre-fix several mounting plates 2 to the inner wall of the aquaculture pond or a special support frame using bolts, welding, or clips to ensure that they remain stable in the horizontal and vertical directions and will not shift due to water flow or operation; then, support rods 4 are fixedly connected to both sides of the bottom of each mounting plate 2. The support rods 4 extend horizontally, and their tops form a flat support surface with sufficient load-bearing capacity to support the bottom structure of the abalone attachment substrate 1; next, the operator slowly pushes or places the abalone attachment substrate 1 into the two support rods 4 from the side or above, so that the bottom surface of the abalone attachment substrate 1 is completely in contact with the top surface of the support rod 4, achieving initial positioning and load-bearing support. Simultaneously, the two lower locking blocks 6 connected to one side of the abalone attachment base 1 slide into the corresponding through grooves on the side wall of the mounting plate 2. The upper inclined surface of the top of the lower locking block 6 contacts the lower inclined surface of the bottom of the upper locking block 15 set in the through groove. During the pushing process, the relative sliding between the inclined surfaces generates an upward component force, forcing the upper locking block 15 to overcome the downward elastic force provided by its top elastic connection structure and compress upward, making room for the lower locking block 6. When the abalone attachment base 1 is fully pushed into place and the lower locking block 6 reaches the innermost side of the through groove, the upper locking block 15 automatically falls back downward under the reset action of the elastic connection structure. Its lower inclined surface fits tightly with the upper inclined surface of the lower locking block 6, forming a lateral limit along the pushing direction and a longitudinal limit in the vertical direction, thereby realizing the connection between the abalone attachment base 1 and the mounting plate 2. The robust and stable mechanical locking between the mounting plates 2 prevents detachment or shaking without the need for additional fasteners. To adjust the distribution density or activity space of abalone on the substrate according to different growth stages or individual sizes, the placement grooves 5 on both sides of the top of the abalone attachment substrate 1 can be operated to push the sliding adjustment plate 16 inside to move horizontally. The end of the adjustment plate 16 cooperates with the horizontal adjustment structure inside the placement groove 5, such as a threaded rod, elastic teeth, or a sliding rail limiter, to precisely control the extension or retraction length of the adjustment plate 16 by twisting, turning, or locking, thereby changing the physical interval between adjacent abalone individuals or the width of the water flow channel, achieving spatial optimization of the local microenvironment. When the farming cycle ends, the surface of the attachment substrate is severely soiled, or batch processing is required... During the next rotation, the operator only needs to lift the upper locking block 15 upwards with one hand to overcome the elasticity of the elastic connection structure and release it from the engagement state of the lower locking block 6, thus releasing the lateral lock. Then, the entire abalone attachment base 1 can be smoothly pulled or lifted upwards along the support rod 4 to detach from the mounting plate 2. The entire disassembly process can be completed by hand without any auxiliary tools such as wrenches or screwdrivers, and without moving adjacent equipment or disassembling the tank structure. This greatly shortens the replacement time and reduces the complexity of operation. The disassembled abalone attachment base 1 can be directly sent to the cleaning area for high-pressure rinsing, disinfection and sterilization, or replaced with new parts. The mounting plate 2 and support rod 4 can be retained in the tank for long-term reuse, forming an efficient operation and maintenance mode of "fixed base + replaceable module", which significantly improves the continuity and flexibility of aquaculture operations.

[0025] Furthermore, the elastic connection structure includes several compression springs 13 and dampers 14 connected together between the upper locking block 15 and the inner wall of the mounting plate 2. The top of the upper locking block 15 is connected to a pull rod 12 that slides through the top of the mounting plate 2. Specifically, through the cooperation of the upper locking block 15, compression springs 13, dampers 14 and pull rod 12, when the operator pulls the pull rod 12 upward, the pull rod 12 drives the upper locking block 15 to move upward synchronously, overcoming the elastic force of the compression springs 13 and compressing the dampers 14, so that the lower inclined surface at the bottom of the upper locking block 15 disengages from the engagement state with the upper inclined surface at the top of the lower locking block 6, thereby releasing the lock. After releasing, under the restoring force of the compression springs 13 and the buffering effect of the dampers 14, the upper locking block 15 falls back smoothly, avoiding structural impact or accidental locking caused by rapid falling, thus achieving the effects of improving the stability of disassembly and assembly operations, extending the service life of the mechanism, and ensuring the safety and reliability of the locking process.

[0026] Furthermore, horizontal grooves are provided on both sides of the inner wall of the placement trough 5. The horizontal adjustment structure includes a sliding block 8 slidably connected inside the two horizontal grooves, a screw rod 9 with one end threaded through the sliding block 8 and rotatably connected to the inner wall of one of the horizontal grooves, and a guide rod 7 with one end slidably through the sliding block 8 and slidably connected to the inner wall of the other horizontal groove. The two ends of the adjustment plate 16 are respectively connected to the two sliding blocks 8. Specifically, through the coordinated arrangement of the placement trough 5, the adjustment plate 16, the sliding block 8, the screw rod 9 and the guide rod 7, when the screw rod 9 is rotated, the sliding block 8 slides smoothly along the horizontal groove under the combined action of the screw rod 9's threaded transmission and the guide rod 7's linear guidance, thereby driving the adjustment plate 16 connected to its two ends to move synchronously within the placement trough 5, realizing continuous stepless adjustment of the distribution spacing of adjacent abalone or the width of the water flow channel. This achieves the effect of precisely controlling the spatial layout according to different growth stages of abalone, optimizing the local water flow environment, and improving the farming density and growth uniformity per unit area.

[0027] Furthermore, one end of the lead screw 9 is rotatably connected to a rotating disk 10 through the side wall of the mounting plate 2. A rotating handle 11 is fixedly connected to one side of the rotating disk 10. Specifically, through the cooperative arrangement of the lead screw 9, the rotating disk 10 and the rotating handle 11, the operator only needs to rotate the rotating handle 11 to drive the lead screw 9 to rotate synchronously through the rotating disk 10, thereby driving the sliding block 8 and the adjusting plate 16 to adjust their positions. This eliminates the need for tools or complicated operations, thereby improving the convenience and efficiency of adjustment operations, reducing the threshold for manual operation, and facilitating rapid on-site response to changes in aquaculture needs.

[0028] Furthermore, the rotating handle 11 is made of metal, and anti-slip grooves are provided on the surface of the rotating handle 11. Specifically, by using metal as the rotating handle 11 and providing anti-slip grooves on its surface, the metal material ensures structural strength and corrosion resistance when operating in humid or salt spray environments, while the anti-slip grooves effectively increase hand friction, preventing adjustment failure or operational errors due to slipping or water contact. This achieves the effects of enhancing operational safety, adapting to high-humidity and high-salt aquaculture environments, improving long-term reliability, and enhancing the human-machine interaction experience.

[0029] Furthermore, a handle is fixedly connected to the top of the pull rod 12, and several mounting plates 2 are connected by a connecting frame 3. Specifically, by setting a handle on the top of the pull rod 12 and connecting several mounting plates 2 by a connecting frame 3, the handle makes it easy for the operator to lift and unlock with one hand, improving human-machine efficiency; while the connecting frame 3 rigidly connects multiple mounting plates 2 into an overall frame structure, which not only enhances the overall stability of the device in the pool and prevents displacement caused by water flow impact or operational shaking, but also facilitates batch installation and unified maintenance, achieving the effects of improving the structural rigidity of the device, simplifying the installation process, and enhancing system synergy and adaptability to large-scale deployment.

[0030] This solution involves the following steps: First, the operator pre-fixes several mounting plates 2 to the inner wall of the aquaculture pond or a dedicated support frame using bolts, welding, or clips. Adjacent mounting plates 2 are rigidly connected by connecting frames 3 to form an overall frame structure, ensuring the entire device remains stable in the horizontal and vertical directions within the pond and preventing displacement due to water flow impact or operational disturbance. Then, support rods 4 are fixedly connected to both sides of the bottom of each mounting plate 2. The support rods 4 extend horizontally, their tops forming a flat and sufficiently load-bearing support platform to support the bottom structure of the abalone attachment base 1. Next, the operator places the abalone attachment base 1 from the side... Slowly push the two supporting rods 4 into place, ensuring their bottom surfaces are fully against the tops of the supporting rods 4, achieving initial positioning and gravity support. Simultaneously, the two lower locking blocks 6 connected to one side of the abalone attachment base 1 slide into the corresponding through slots on the side wall of the mounting plate 2. The upper inclined surface of the top of the lower locking block 6 contacts the lower inclined surface of the bottom of the upper locking block 15 set in the through slot. During the pushing process, the inclined surfaces squeeze each other, generating an upward component force, forcing the upper locking block 15 to overcome the downward elastic force provided by the elastic connection structure connected to its top—namely, several compression springs 13 and dampers 14—and compress upward, making room for the lower locking block 6. When the abalone attachment base 1 is fully pushed in... When the lower locking block 6 reaches the innermost side of the through groove, the upper locking block 15 smoothly falls back under the restoring force of the compression spring 13 and the buffering effect of the damper 14. Its lower inclined surface tightly engages with the upper inclined surface of the lower locking block 6, forming a two-way limit in both the lateral and longitudinal directions. This achieves a firm and secure mechanical lock between the abalone attachment base 1 and the mounting plate 2 without any additional fasteners. If it is necessary to adjust the distribution density or activity space of the abalone according to different growth stages or individual sizes, the placement grooves 5 opened on both sides of the top of the abalone attachment base 1 can be operated. The inner walls of the placement grooves 5 are provided with horizontal grooves on both sides. The sliding block 8 is slidably connected in the horizontal groove. The two ends of the adjusting plate 16 are respectively connected to the horizontal grooves. Two sliding blocks 8 are fixedly connected. One end of the screw 9 is threaded through the sliding block 8 and rotatably connected to the inner wall of one of the horizontal grooves. One end of the guide rod 7 slides through the sliding block 8 and is slidably connected to the inner wall of the other horizontal groove. The operator only needs to rotate the handle 11 to drive the rotating disk 10 fixedly connected to it to rotate synchronously, thereby driving the screw 9 to rotate. Under the synergistic effect of the screw 9 threaded transmission and the guide rod 7 linear guidance, the sliding block 8 slides smoothly along the horizontal groove, thereby driving the adjustment plate 16 to move synchronously in the placement groove 5, accurately adjusting the physical distance or water flow channel width between adjacent abalone individuals, and realizing the spatial dynamic optimization of the local microenvironment.When the aquaculture cycle ends, the surface of the substrate becomes severely soiled, or batch rotation is required, the operator only needs to pull the lever 12 upwards with one hand—its top has a handle for easy gripping. The lever 12 slides upwards through the top of the mounting plate 2 and moves the upper locking block 15 upwards simultaneously, overcoming the elasticity of the compression spring 13 and compressing the damper 14. This causes the lower slope of the bottom of the upper locking block 15 to disengage from the engagement with the upper slope of the top of the lower locking block 6, releasing the lateral lock. Then, the entire abalone substrate 1 can be smoothly pulled out along the support rod 4. Mounting plate 2 can be disassembled entirely by hand, without any tools, and without moving adjacent equipment or dismantling the tank structure. This greatly shortens replacement time and reduces operational complexity. The disassembled abalone attachment base 1 can be directly sent to the cleaning area for high-pressure rinsing, disinfection, or replacement with new parts. Meanwhile, the mounting plate 2, support rod 4, connecting frame 3, and other basic structures can be retained in the tank for long-term reuse, forming a highly efficient operation and maintenance model of "fixed base + replaceable module," significantly improving the continuity, flexibility, and large-scale management capabilities of aquaculture operations.

[0031] The comprehensive benefits of this device fully cover and effectively solve various core problems existing in traditional technologies: The rigid connection structure between the mounting plate 2 and the connecting frame 3 enhances the overall frame's resistance to water flow impact and structural stability within the aquaculture pond, preventing abalone stress or device displacement due to shaking. It also facilitates batch installation and unified maintenance, improving system deployment efficiency and scalability. The stable support of the abalone attachment base 1 by the support rod 4 ensures a good load-bearing foundation before locking, preventing structural deformation or locking failure due to suspension or uneven loading. The inclined guide cooperation between the lower locking block 6 and the upper locking block 15, combined with the elastic connection structure formed by the compression spring 13 and the damper 14, achieves a tool-free quick-release mechanism of "push-in automatic locking, pull-out quick unlocking," which is simple to operate, responds quickly, and significantly reduces the intensity and time cost of manual replacement. The handle at the top of the pull rod 12 makes the unlocking operation ergonomic, allowing for one-handed operation and improving human-machine interaction efficiency. The placement groove 5, adjusting plate 16, sliding block 8, lead screw 9, and guide... The precision adjustment system composed of the guide rod 7 enables continuous stepless adjustment of the abalone distribution spacing and water flow channel width. It can precisely optimize the spatial layout according to different growth stages, improving the utilization rate of water units and the uniformity of growth. Through the linkage design of the rotating disk 10 and the rotating handle 11, the complex thread adjustment is transformed into a simple rotation operation, greatly improving the convenience of adjustment. The rotating handle 11 is made of metal and has anti-slip grooves to ensure stable operation in high humidity, high salinity and slippery farming environments, preventing slippage or corrosion failure, extending service life and ensuring operational safety. The overall structure is modular and standardized. The basic components can be reused for a long time, and consumable components can be replaced independently. This reduces the overall operating cost, facilitates cleaning management and disease prevention and control, effectively controls the accumulation of biofouling and the risk of pathogen transmission, and truly meets the comprehensive needs of modern abalone farming for "efficient operation, flexible adjustment, clean management, structural stability, operational safety and environmental adaptability". It provides solid, reliable and highly practical technical support for the standardized, intensive and sustainable development of the aquaculture industry.
