Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of squid observation devices, specifically a device for artificial incubation and observation of needleless squid. Background Technology
[0002] The needleless squid (Sepia spp.) is a medium-sized, annual squid, commonly known as cuttlefish. It grows quickly and has delicious, flavorful meat, making it a popular seafood delicacy. In the early 21st century, to save this endangered species, a team from Zhejiang Ocean University pioneered artificial breeding research by having divers locate a small cluster of fertilized needleless squid eggs in the Dongji waters off Zhoushan.
[0003] Currently, the artificial breeding of *Sepia mansoni* mostly relies on purchasing wild squid in the spring as breeding stock. This method is characterized by small-scale production and unstable supply, making it difficult to meet the large-scale demand for stock enhancement and release. Large-scale marine hatching technology for *Sepia mansoni* can effectively increase the scale of artificially bred populations. During marine hatching, to facilitate real-time observation of the hatching process and prevent accidents, monitoring devices are typically used to monitor the development of fertilized eggs. However, these monitoring devices are currently fixed in location. When using net cage incubators, the fertilized eggs are vertically distributed, making it difficult for fixed monitoring devices to comprehensively observe the hatching of eggs at a distance, hindering real-time and comprehensive monitoring of the hatching dynamics.
[0004] Therefore, this utility model provides an artificial incubation observation device for the needleless squid. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The artificial incubation and observation device for the needleless squid of the present utility model includes a net cage incubator, in which several incubation ropes are installed, and a monitor is installed inside the net cage incubator; a connecting plate is fixedly installed at the top of the net cage incubator, and a first electric push rod is fixedly installed on one side of the connecting plate. A rectangular frame is fixedly installed at the output end of the first electric push rod, and a sliding groove for the rectangular frame to slide is opened on one side of the connecting plate; a servo motor is fixedly installed inside the rectangular frame, and a lead screw is fixedly installed at the output end of the servo motor. The bottom of the lead screw is connected to the rectangular frame, and a hollow rectangular block is movably connected to the surface of the lead screw. A second electric push rod is fixedly installed inside the rectangular block, and a monitor is fixedly installed at the output end of the second electric push rod.
[0007] Furthermore, two multi-level telescopic plates are fixedly installed inside the rectangular frame. The ends of the two multi-level telescopic plates that are close to each other are respectively fixedly connected to the rectangular block. The multi-level telescopic plates are composed of several hollow plates that are slidably connected, and sealing gaskets are fixedly installed on both sides of the plates.
[0008] Furthermore, two symmetrically arranged elastic blocks are fixedly installed on one side of the rectangular frame, an air outlet pipe connected to the interior is fixedly installed on one side of the elastic block, and a top plate is fixedly installed on the top of the rectangular block.
[0009] Furthermore, the top plate has arc-shaped sides, rounded corners at the top, and several rollers rotatably connected to the sides.
[0010] Furthermore, a water tank is fixedly installed on one side of the rectangular frame, and a water outlet pipe connected to the inside is fixedly installed on the top of the water tank.
[0011] Furthermore, the outlet pipe is slidably connected to an extension pipe via an elastic rope. Several baffles are fixedly installed inside the extension pipe. One end of the extension pipe is rotatably connected to an end cap via a torsion spring. An arc-shaped positioning rod is fixedly installed on one side of the end cap. A positioning groove adapted to the positioning rod is opened on the surface of the extension pipe.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The artificial incubation and observation device for *Sepia speciosa* described in this utility model, during incubation, involves activating a first electric push rod on a connecting plate. This push rod moves a rectangular frame along a slide rail, causing the monitor to move to a suitable position and stop. Then, a servo motor within the rectangular frame is activated. This servo motor, via a lead screw, moves the rectangular block, multi-stage telescopic plate, the first electric push rod, and the monitor up and down, facilitating the monitor's downward movement to observe the fertilized eggs of *Sepia speciosa* within the net cage incubator. As the rectangular block moves into the net cage incubator, a second electric push rod within the rectangular block is simultaneously activated, causing the monitor to move laterally, bringing it closer to the fertilized eggs on the incubation rope. This allows the monitor to get closer to the fertilized eggs at the far end, enabling comprehensive and detailed observation. This allows for real-time monitoring of the incubation status of the fertilized eggs throughout the net cage incubator, providing real-time dynamic tracking.
[0014] 2. The artificial incubation and observation device for *Sepia speciosa* described in this utility model, after the monitor completes the observation of the fertilized eggs of *Sepia speciosa* in the net cage incubator, the servo motor drives the rectangular block and other components to move upward and reset. After the rectangular block moves to its initial position, the servo motor is restarted, causing the servo motor to drive the rectangular block and top plate upward through the lead screw for a transitional reset. Then, the top plate and rollers on both sides squeeze the elastic block, causing the gas inside the elastic block to blow towards the rectangular block and the monitor, quickly blowing off any residual seawater on their surface. As the top plate continues to move upward, it squeezes the water tank, causing the water inside the tank to enter the outlet pipe and contact the baffle and end cap in the extension pipe, thus pushing the extension pipe away from the outlet pipe and closer to the rectangular block and the monitor. As the water tank is continuously squeezed, the water inside continuously flows into the outlet pipe and extension pipe, then rotates and opens the end cap, causing the end cap, along with the positioning rod, to rotate and insert into the positioning groove for temporary fixation. At this time, the water sprayed from the extension pipe will rinse the rectangular block and the monitor, further removing residual seawater and reducing the corrosive effect of seawater on the rectangular block and the monitor.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 6 As shown in the embodiment of this utility model, an artificial incubation and observation device for the needleless squid includes a net cage incubator 1, with several incubation ropes 2 installed inside the net cage incubator 1, and a monitor 11 installed inside the net cage incubator 1. A connecting plate 3 is fixedly installed at the top inside the net cage incubator 1, and a first electric push rod 4 is fixedly installed on one side of the connecting plate 3. A rectangular frame 5 is fixedly installed at the output end of the first electric push rod 4, and a sliding groove 6 is provided on one side of the connecting plate 3 to assist the sliding of the rectangular frame 5. A servo motor 7 is fixedly installed inside the rectangular frame 5, and a lead screw 8 is fixedly installed at the output end of the servo motor 7. The bottom of the lead screw 8 is connected to the rectangular frame 5, and a hollow rectangular block 9 is movably connected to the surface of the lead screw 8. A second electric push rod 10 is fixedly installed inside the rectangular block 9, and the monitor 11 is fixedly installed at the output end of the second electric push rod 10.
[0025] Specifically, two multi-level telescopic plates 12 are fixedly installed inside the rectangular frame 5. The ends of the two multi-level telescopic plates 12 that are close to each other are fixedly connected to the rectangular block 9. The multi-level telescopic plates 12 are composed of several hollow plates that are slidably connected. Sealing gaskets 13 are fixedly installed on both sides of the plates.
[0026] During operation, the fertilized eggs of the Japanese squid (Sepia speciosa) are typically collected and strung together before being placed in the net-cage incubator 1. This method effectively prevents the fertilized eggs from being eaten by fish, ensuring a successful hatching process. It's important to note that when the net-cage incubator 1 is placed in seawater for incubation, its top connecting plate 3 and the first electric push rod 4 remain above the sea surface, not submerged. During incubation, activating the first electric push rod 4 on the connecting plate 3 moves the rectangular frame 5 via the slide rail 6, thereby moving the monitor 11 to the appropriate position and stopping. Then, the servo motor 7 within the rectangular frame 5 is activated. The servo motor 7, via the lead screw 8, moves the rectangular block 9, the multi-stage telescopic plate 12, the first electric push rod 4, and the monitor 11 up and down, allowing the monitor 11 to be lowered to observe the fertilized eggs of the Japanese squid within the net-cage incubator 1. As the rectangular block 9 moves down into the net cage incubator 1, the second electric push rod 10 inside the rectangular block 9 is simultaneously activated, causing the second electric push rod 10 to move laterally along with the monitor 11, thus getting closer to the fertilized eggs of the Japanese squid on the hatching rope 2. This also allows the monitor 11 to get closer to the fertilized eggs of the Japanese squid at the far end, enabling comprehensive and detailed observation. It allows for real-time monitoring of the hatching status of the fertilized eggs of the Japanese squid in various locations within the net cage incubator 1, and real-time tracking of the dynamics.
[0027] It should be noted that when the two multi-stage telescopic plates 12 move in conjunction with the rectangular block 9, the sealing gaskets 13 on the sides of the internal plates will seal during the telescopic movement, thereby reducing the amount of seawater entering the multi-stage telescopic plates 12 and the rectangular frame 5.
[0028] Two symmetrically arranged elastic blocks 15 are fixedly installed on one side of the rectangular frame 5. An air outlet pipe 16 connected to the interior is fixedly installed on one side of the elastic block 15. A top plate 14 is fixedly installed on the top of the rectangular block 9. The two sides of the top plate 14 are arc-shaped, and the top of the top plate 14 has rounded corners. Several rollers 17 are rotatably connected to the two sides of the top plate 14.
[0029] Specifically, a water tank 18 is fixedly installed on one side of the rectangular frame 5, and a water outlet pipe 19 connected to the inside is fixedly installed on the top of the water tank 18. An extension pipe 20 is slidably connected to the inside of the water outlet pipe 19 via an elastic rope 21. Several baffles 22 are fixedly installed inside the extension pipe 20. One end of the extension pipe 20 is rotatably connected to an end cap 23 via a torsion spring. An arc-shaped positioning rod 24 is fixedly installed on one side of the end cap 23, and a positioning groove 25 that matches the positioning rod 24 is opened on the surface of the extension pipe 20.
[0030] During operation, after the monitor 11 completes its observation of the fertilized eggs of the squid in the net cage incubator 1, the servo motor 7 drives the rectangular block 9 and other components to move upwards and reset. Once the rectangular block 9 reaches its initial position, the servo motor 7 is restarted, causing it to drive the rectangular block 9 and the top plate 14 upwards via the lead screw 8. This, in turn, uses the top plate 14 and the rollers 17 on both sides to compress the elastic block 15, causing the gas inside the elastic block 15 to blow towards the rectangular block 9 and the monitor 11, quickly removing any residual seawater from their surfaces. As the top plate 14 continues to move upwards, it compresses the water tank 18, causing the water in the tank to enter the outlet pipe 19 and contact the baffle 22 and end cap 23 in the extension pipe 20. This pushes the extension pipe 20 away from the outlet pipe 19, bringing it closer to the rectangular block 9 and the monitor 11. As the water tank 18 is continuously compressed, water flows into the outlet pipe 19 and extension pipe 20, causing the top cap 23 to rotate and open, temporarily fixing it into the positioning groove 25 along with the positioning rod 24. At this time, water sprayed from the extension pipe 20 rinses the rectangular block 9 and the monitor 11, further removing residual seawater and reducing its corrosive effects. After these steps, the rectangular block 9 moves the top plate 14 back to its initial position, the end cap 23, under the action of the torsion spring, moves the positioning rod 24 out of the positioning groove 25 and resets, and the extension pipe 20 slides back to its original position under the action of the elastic rope 21, facilitating future use.
[0031] Working Principle: Fertilized eggs of the Japanese squid (Sepia speciosa) are typically collected and strung together before being placed in a net-cage incubator 1. This method effectively prevents the fertilized eggs from being eaten by fish, ensuring successful hatching. It's important to note that when the net-cage incubator 1 is placed in seawater for incubation, its top connecting plate 3 and the first electric push rod 4 remain above the sea surface, not submerged. During incubation, activating the first electric push rod 4 on the connecting plate 3 moves the rectangular frame 5 via the slide rail 6, thus moving the monitor 11 to a suitable position and stopping. Then, the servo motor 7 within the rectangular frame 5 is activated. The servo motor 7, via the lead screw 8, moves the rectangular block 9, the multi-stage telescopic plate 12, the first electric push rod 4, and the monitor 11 up and down, facilitating the monitor 11's downward movement to observe the fertilized eggs of the Japanese squid within the net-cage incubator 1. As the rectangular block 9 moves down into the net cage incubator 1, the second electric push rod 10 inside the rectangular block 9 is activated simultaneously, causing the second electric push rod 10 to move laterally along with the monitor 11, thus getting closer to the fertilized eggs of the Japanese needleless squid on the hatching rope 2. This also allows the monitor 11 to get closer to the fertilized eggs of the Japanese needleless squid at the far end for observation.
[0032] After the monitor 11 completes its observation of the fertilized eggs of the squid in the net cage incubator 1, the servo motor 7 drives the rectangular block 9 and other components to move upwards and reset. Once the rectangular block 9 reaches its initial position, the servo motor 7 is restarted, causing it to drive the rectangular block 9 and the top plate 14 upwards via the lead screw 8. This, in turn, uses the top plate 14 and the rollers 17 on both sides to compress the elastic block 15, causing the gas inside the elastic block 15 to blow towards the rectangular block 9 and the monitor 11, quickly removing any residual seawater from their surfaces. As the top plate 14 continues to move upwards, it compresses the water tank 18, causing the water in the tank to enter the outlet pipe 19 and contact the baffle 22 and end cap 23 in the extension pipe 20. This pushes the extension pipe 20 away from the outlet pipe 19, bringing it closer to the rectangular block 9 and the monitor 11. As the water tank 18 is continuously compressed, water inside continuously flows into the outlet pipe 19 and the extension pipe 20, thereby rotating and opening the end cover 23, causing the end cover 23, along with the positioning rod 24, to rotate and insert into the positioning groove 25 for temporary fixation. At this time, the water sprayed from the extension pipe 20 will rinse the rectangular block 9 and the monitor 11, further removing residual seawater and reducing the corrosive effect of seawater on the rectangular block 9 and the monitor 11.
