Description

Technical Field

[0001] This utility model relates to the field of fish ecological technology, and in particular to a migration simulation device for aquaculture. Background Technology

[0002] In the field of aquaculture, migration simulation devices are used to simulate the migration environment of fish, meet the specific growth needs of fish, and help fish grow healthily in the breeding environment. Common types include fish ladders, recirculating aquaculture systems, and swimming aquaculture platforms. Among them, fish ladders, as an important migration simulation device, are usually built next to water conservancy facilities such as dams. They are composed of continuous stepped water tanks and can help fish bypass obstacles such as dams to complete their migration, maintain the stability of the aquatic ecosystem, and ensure the reproduction and survival of fish populations.

[0003] However, existing fish ladders have revealed many drawbacks in practical applications. With a rich variety of fish species, different species have different migratory habits, body sizes, and physical conditions, resulting in vastly different requirements for the height of the fish ladder steps. The step height of traditional fish ladders cannot be changed once set. Faced with a diverse range of farmed fish, if aquaculture operators want to accurately simulate the migratory environment of various fish species, they have to purchase special fish ladders adapted to different fish species. This undoubtedly increases the equipment procurement cost significantly. Moreover, the installation, debugging, and maintenance of different fish ladders also require a lot of time and effort, causing great inconvenience to aquaculture work and hindering the efficient development of the aquaculture industry.

[0004] Therefore, it is necessary to provide a new migration simulation device for aquaculture to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a migration simulation device for aquaculture.

[0006] The aquaculture migration simulation device provided by this utility model includes: a channel, a fixed step fixedly connected to the bottom of one end of the channel, multiple sets of movable steps equidistantly installed on one side of the fixed step, nozzles for spraying water installed on both sides of the fixed step and the movable step, a connecting plate fixedly connected to the bottom of the fixed step and the movable step, a connecting rod fixedly connected to the bottom of the connecting plate, an adjusting plate installed inside the channel, and the connecting rod connected to the movable step slidably connected to the adjusting plate.

[0007] Preferably, multiple sets of T-shaped grooves are equidistantly provided on the inner wall of the walkway, and T-shaped sliders are fixedly connected to both sides of the fixed step and the movable step, and the T-shaped sliders slide in the T-shaped grooves.

[0008] Preferably, the nozzle is fixed to the top of the T-shaped slider.

[0009] Preferably, the adjusting plate is U-shaped, and a rectangular groove is provided on the inner side of the adjusting plate, and both ends of the connecting rod connected to the movable step slide within the rectangular groove.

[0010] Preferably, the length of each connecting rod is longer than the length of the connecting plate, and the length of the connecting rod connected to the fixed step is longer than the length of the connecting rod connected to the movable step. Both ends of the connecting rod connected to the fixed step pass through the adjustment plate and are fixed to the walkway.

[0011] Preferably, an electric push rod is fixedly connected inside the walkway, and the output end of the electric push rod is fixed to the bottom of the rightmost movable step.

[0012] Preferably, the horizontal height of the top of the connecting rod is lower than the horizontal height of the bottom of the fixed step.

[0013] Preferably, the walkway is sealed to the fixed step, the movable step, and the T-shaped slider.

[0014] Compared with related technologies, the migration simulation device for aquaculture provided by this utility model has the following advantages:

[0015] Beneficial effects:

[0016] Adapting to diverse aquaculture needs:

[0017] This device uses an electric push rod to drive the height adjustment of the movable steps, which can flexibly change the height and slope of the fish ladder. For fish with different migratory habits and physiological characteristics, aquaculture personnel do not need to purchase multiple special fish ladders. One set of equipment can meet diverse simulation needs, effectively reducing equipment purchase and replacement costs, improving aquaculture efficiency, and enhancing the versatility and practicality of the device.

[0018] Accurately simulates the natural environment:

[0019] The movable steps can be adjusted synchronously, and together with the nozzles on both sides of the fixed steps and the movable steps, water can be sprayed to create a diverse water flow environment. This highly replicates the complex water flow and terrain conditions that fish encounter during their natural migration. This precise simulation helps to improve the growth environment of fish, promote their healthy growth, improve the quality of fish meat, and contribute to green and ecological aquaculture.

[0020] Synchronous adjustment simplifies the operation process:

[0021] The synchronized adjustment mechanism of the activity stages allows farmers to adjust multiple activity stages in a coordinated manner simply by operating an electric push rod. The simple adjustment method makes it easy for even novice farmers to get started quickly, thus improving the efficiency of farming work.

[0022] Efficient utilization of aquaculture space: When adjusting the height of the activity steps, the synchronous adjustment function can ensure that the spacing between each step remains uniform, avoiding the waste of aquaculture space due to uneven step spacing. This ensures that a more reasonable migration simulation area is created for fish within the limited aquaculture space, thereby improving the utilization rate of the aquaculture space.

It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 4 A migration simulation device for aquaculture includes: a channel 1, a fixed step 2 fixedly connected to the bottom of one end of the channel 1, multiple sets of movable steps 3 equidistantly installed on one side of the fixed step 2, spray nozzles 4 for spraying water installed on both sides of the fixed step 2 and the movable steps 3, a connecting plate 5 fixedly connected to the bottom of the fixed step 2 and the movable steps 3, a connecting rod 6 fixedly connected to the bottom of the connecting plate 5, an adjusting plate 7 installed inside the channel 1, the connecting rod 6 connected to the movable steps 3 being slidably connected to the adjusting plate 7, an electric push rod 11 fixedly connected inside the channel 1, the output end of the electric push rod 11 being fixed to the bottom of the rightmost movable step 3, and the horizontal height of the top of the connecting rod 6 being lower than the horizontal height of the bottom of the fixed step 2;

[0031] It should be noted that: at the same time, the nozzles 4 on both sides can create complex water flow to simulate the natural environment and provide suitable migratory conditions for fish. An electric push rod 11 is fixed in the channel 1, and its output end is fixed to the bottom of the rightmost movable step 3. The electric push rod 11 provides power for the height adjustment of the movable step 3. By operating the electric push rod 11, the aquaculture personnel can easily and quickly adjust the height of the movable step 3. Compared with manual adjustment, it greatly improves the adjustment efficiency, reduces labor intensity, simplifies the operation process, and makes it convenient for aquaculture personnel to use.

[0032] Please see Figure 1 and Figure 2 The inner wall of the walkway 1 is provided with multiple sets of T-shaped grooves 8 at equal intervals. T-shaped sliders 9 are fixedly connected to both sides of the fixed step 2 and the movable step 3. The T-shaped sliders 9 slide in the T-shaped grooves 8. The nozzle 4 is fixed to the top of the T-shaped slider 9. The walkway 1 is sealed to the fixed step 2, the movable step 3 and the T-shaped slider 9.

[0033] It should be noted that: the inner wall of the channel 1 is equipped with multiple sets of T-shaped sliding grooves 8, and the fixed step 2 and the movable step 3 have T-shaped sliders 9 on both sides and slide in the sliding grooves. This structure ensures the stability and smoothness of the fixed step 2 and the movable step 3 during the height adjustment process, prevents them from shaking or shifting, makes the entire device structure stable, ensures the fish ladder height adjustment is accurate and reliable, and extends the service life of the equipment.

[0034] Please see Figure 1 and Figure 3 The adjustment plate 7 has a U-shaped design. A rectangular slide groove 10 is provided on the inner side of the adjustment plate 7. Both ends of the connecting rod 6 connected to the movable step 3 slide in the rectangular slide groove 10. The length of the connecting rod 6 is longer than the length of the connecting plate 5. The length of the connecting rod 6 connected to the fixed step 2 is longer than the length of the connecting rod 6 connected to the movable step 3. Both ends of the connecting rod 6 connected to the fixed step 2 pass through the adjustment plate 7 and are fixed to the walkway 1.

[0035] It should be noted that: the adjusting plate 7 is U-shaped with a rectangular groove 10 on its inner side. The two ends of the connecting rod 6 of the movable step 3 slide within the groove. The U-shaped adjusting plate 7, combined with the rectangular groove 10, provides a stable sliding track for the connecting rod 6 of the movable step 3. On the other hand, it allows the adjusting plate 7 to rotate around the connecting rod 6 of the fixed step 2 as an axis when the height of the movable step 3 is adjusted, thereby driving the other movable steps 3 to rise and fall synchronously, achieving efficient and synchronous adjustment of the movable steps 3. The design of the length and connection method of the connecting rod 6, namely, the connecting rod 6 is longer than the connecting plate 5, the connecting rod 6 of the fixed step 2 is longer than the connecting rod 6 of the movable step 3 and passes through the adjusting plate 7 and is fixed to the walkway 1, ensures that the adjusting plate 7 has stable support and a center of rotation during the height adjustment of the movable step 3, ensuring the stability and accuracy of the height adjustment of the movable step 3. At the same time, the setting of connecting rods 6 of different lengths, in conjunction with the adjusting plate 7, realizes the synchronous and orderly adjustment of the movable steps 3.

[0036] The working principle of the migration simulation device for aquaculture provided by this utility model is as follows:

[0037] Preparation phase:

[0038] Device inspection: Before starting the equipment, the staff will conduct a comprehensive inspection of the simulation device to check whether the walkway 1 is damaged or blocked, and to confirm that the fixed step 2, the movable step 3 and all connecting parts are securely connected. At the same time, check whether the nozzle 4, the electric push rod 11 and other equipment can operate normally, and ensure that there are no foreign objects in the rectangular slide groove 10 of the adjustment plate 7 and the T-shaped slide groove 8 on the inner wall of the walkway 1, so as not to affect the normal operation of the device.

[0039] Parameter preset: Based on the migratory habits of the fish being farmed, the staff determines the adjustment target of the active step 3, presets the extension and retraction length of the electric push rod 11, and connects the electric push rod 11 to the bottom of the rightmost active step 3. By controlling its extension and retraction, the position of the active step 3 can be adjusted.

[0040] Activity Stage 3 Height Adjustment Phase:

[0041] Electric push rod 11 drives the first step to move: After the system issues the command, the electric push rod 11 starts and its output end applies a pushing or pulling force to the rightmost movable step 3. At this time, the T-shaped slider 9 at the bottom of the rightmost movable step 3 will slide up or down along the T-shaped groove 8 on the inner wall of the passage 1. At the same time, the connecting rod 6 connected to the movable step 3 will move up or down in the vertical direction as the movable step 3 moves.

[0042] Adjusting plate 7 rotates around the axis: As the rightmost connecting rod 6 rises and falls, it will drive the end of the adjusting plate 7 to move up or down synchronously. Since the adjusting plate 7 is U-shaped, a rectangular sliding groove 10 is opened on the inner side of the adjusting plate 7. The two ends of the connecting rod 6 connected to the fixed step 2 pass through the adjusting plate 7 and are fixed to the walkway 1. Therefore, the adjusting plate 7 will rotate up or down around the axis of the connecting rod 6 connected to the fixed step 2 as the rotation center. During this process, one end of the adjusting plate 7 rotates around the axis of the fixed connecting rod 6, while the other end moves up and down with the rightmost connecting rod 6.

[0043] Synchronous adjustment of multiple movable steps 3: During the rotation of the adjustment plate 7, it will push or pull the connecting rods 6 connected to other movable steps 3. The two ends of these connecting rods 6 also slide in the rectangular slide grooves 10 inside the adjustment plate 7, so they will rise or fall with the rotation of the adjustment plate 7. Since each movable step 3 is closely connected to the adjustment plate 7 through the connecting rods 6, the other movable steps 3 except the rightmost movable step 3 will rise or fall synchronously with the rightmost movable step 3, and the height and slope of the fish ladder will be changed in a regular manner to meet the needs of different fish migration simulation.

[0044] Simulated water flow environment stage:

[0045] Spraying water from nozzle 4: As the positions of fixed step 2 and movable step 3 are adjusted into place, nozzle 4 installed on both sides of fixed step 2 and movable step 3 begins to work. The nozzle 4 is fixed to the top of T-shaped slider 9, and T-shaped slider 9 slides in T-shaped groove 8 on the inner wall of channel 1 to ensure the stable position of nozzle 4. The nozzle 4 sprays water into channel 1. Under the obstruction and guidance of fixed step 2 and movable step 3, water flows with different speeds and directions are formed to simulate the complex water flow environment encountered by fish during migration.

[0046] Maintaining stable water flow: Since the channel 1 is connected to the fixed step 2, the movable step 3, and the T-shaped slider 9 in a sealed manner, water leakage is effectively prevented, ensuring the stability of the simulated water flow environment and providing fish with water flow conditions close to their natural migration state.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
