[0030] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1-11The above describes a habitat device for *Leptochloa gracilis* used in photovoltaic aquaculture, comprising a suspended airbag 1, an installation frame 2 fixedly connected to the inner side of the suspended airbag 1, the installation frame 2 providing an installation position, a fixing frame 3 fixedly connected to the inner side of the installation frame 2, the fixing frame 3 providing an installation base, a splicing frame 6 provided between the fixing frame 3 and the installation frame 2, and modular habitat mechanisms 4 provided at the bottom of both the fixing frame 3 and the splicing frame 6. The splicing frame 6 is detachable for easy removal of the modular habitat mechanisms 4, a net cover mechanism 5 is provided on the outside of the modular habitat mechanisms 4 to prevent blockage of the outside of the modular habitat mechanisms 4, a splicing mechanism 7 is provided on the outside of the splicing frame 6 to fix the splicing frame 6, a positioning mechanism 8 is provided inside the splicing frame 6 to position the modular habitat mechanisms 4, and a storage box 9 is provided inside the installation frame 2.

[0033] The modular habitat mechanism 4 includes multiple habitat blocks 401. A groove 402 is provided on the top of each habitat block 401, and a sliding strip 403 is fixedly connected to the bottom of each habitat block 401. The sliding strip 403 slides into the groove 402, allowing for the longitudinal installation of multiple habitat blocks 401. A splicing frame 404 and a splicing slider 405 are fixedly connected to the side walls of each habitat block 401. The splicing of the splicing frame 404 and the splicing slider 405 allows for the lateral splicing of multiple habitat blocks 401. Multiple habitat holes 406 are provided inside each habitat block 401. These holes are horizontally positioned inside the habitat block 401, providing space for large prawns to enter. Multiple drainage holes 407 are provided inside each habitat block 401. These drainage holes 407 are vertically positioned inside the habitat block 401 and are relatively small, preventing larger prawns from falling out and facilitating easy access. As the water flows out, multiple sliding grooves 402 are slidably connected to the bottom of the fixed frame 3 and the splicing frame 6. When assembling the device, firstly, slide the sliding bar 403 at the bottom of one perch block 401 into the sliding groove 402 at the top of another perch block 401 to complete the splicing of two perch blocks 401 in the longitudinal direction. Then, slide a splicing slider 405 into the interior of another splicing slide frame 404 to complete the splicing of two perch blocks 401 in the transverse direction. This allows for mutual restraint through longitudinal and transverse splicing, thereby improving the stability of the splicing of multiple perch blocks 401. Next, remove the splicing frame 6 from the fixed frame 3, slide the sliding groove 402 on the top perch block 401 into the bottom of the fixed frame 3, and slide another set of top perch blocks 401 into the bottom of the splicing frame 6. Finally, install the splicing frame 6 on the fixed frame 3 through the splicing mechanism 7 to complete the assembly of the device.

[0034] The netting mechanism 5 includes two fixed slide rails 501, which are fixedly connected to the outer walls of the perch block 401 on both sides. Sliding sleeves 502 are slidably connected to the outside of each fixed slide rail 501. A bent strip 503 is fixedly connected between the two sliding sleeves 502. The sliding sleeves 502 can slide outside the fixed slide rails 501, thus restricting the movement trajectory of the bent strip 503. Two blocking nets 504 are fixedly connected to the bottom of the bent strip 503. When unfolded, the blocking nets 504 can cover the outside of the perch block 401, thereby sealing the perch hole 406. To prevent the escape of the giant prawn, the bottom of the barrier net 504 is fixedly connected to the bottom of the habitat block 401. The side wall of the bent strip 503 is fixedly connected to the fixing rod 505. The top of the sliding sleeve 502 is fixedly connected to two pull ropes 506. The top of the pull rope 506 and the outer bottom are both fixedly connected to the spring hooks 507. The fixing rod 505 can make the spring hooks 507 on the lower pull rope 506 fit in, so that the uppermost barrier net 504 can be fully opened and the lower barrier net 504 can be fully opened. The two side walls of the habitat block 401 are fixedly connected to the sleeve posts 508.

[0035] When assembling the perch blocks 401, firstly, the top of the pull rope 506 on the lower perch block 401 is engaged with the fixed sleeve rod 505 of the upper perch block 401 via the spring clip hook 507. The spring clip hook 507 on the top of the pull rope 506 on the uppermost perch block 401 is then engaged with the sleeve post 508 of the uppermost perch block 401. When the barrier net 504 needs to be raised, firstly, the uppermost spring clip hook 507 is detached from the sleeve post 508. At this time, the uppermost pull rope 506 is pulled upwards, thereby causing the bending strip 503 to move upwards, thus allowing passage... The fixed lever 505 drives the lower pull rope 506 to rise, which in turn drives the lower bending strip 503 to rise. At this time, the barrier net 504 can be pulled up and unfolded to cover the outside of the habitat block 401, blocking the habitat hole 406 and preventing the Gryphon shrimp inside the habitat block 401 from escaping. When the spring hook 507 at the bottom of the pull rope 506 moves to the sleeve post 508, the uppermost spring hook 507 can be engaged with the outside of the uppermost sleeve post 508, thereby preventing the bending strip 503 from falling and causing the barrier net 504 to retract.

[0036] The splicing mechanism 7 includes four mounting bases 701, which provide installation positions. The bottoms of the four mounting bases 701 are fixedly connected to the tops of both ends of the splicing frame 6. A wrench 702 is rotatably connected to the top of each mounting base 701, allowing for easy operation by the user. A limiting sleeve 703 is fixedly connected to one end of the top of each mounting base 701. A sliding post 704 is slidably connected inside the limiting sleeve 703, restricting the movement trajectory of the sliding post 704. The sliding post 704 and the wrench 702 are rotatably connected. A rotating rod 705 is connected, which can rotate. When the rotating rod 705 is in a horizontal state, the force on the sliding column 704 and the force on the wrench 702 are both lateral, so the rotating rod 705 will not rotate, and the sliding column 704 will not retract. Multiple embedded blocks 706 are fixedly connected to all four sides of the splicing frame 6. Two splicing columns 707 are fixedly connected to the inner two sides of the mounting frame 2. The splicing columns 707 provide the installation position, and the outside of the splicing columns 707 is slidably connected to a sliding sleeve 7. 08. The sliding sleeve 708 can be fitted onto the joint between the splicing frame 6 and the splicing column 707, thereby fixing the splicing frame 6 inside the mounting frame 2. Stabilizing rods 709 are slidably connected to both ends of the sliding sleeve 708. A return spring 710 is fitted around the outside of the stabilizing rod 709. The stabilizing rod 709 provides the installation position and maintains the stability of the return spring 710's extension and retraction. A fixing post 712 is fixedly connected to the top of the sliding sleeve 708, providing the contact position for the sliding column 704. The inner... Multiple splicing columns 713 are fixedly connected to the side wall away from the fixing frame 3. The top of the fixing frame 3, splicing column 707 and splicing column 713 are all provided with an embedding groove 714. The embedding block 706 is engaged with the embedding groove 714. One end of the return spring 710 is fixedly connected to the side of the sliding sleeve 708 near the mounting frame 2, and the other end of the return spring 710 is fixedly connected to the inner wall of the mounting frame 2. One end of the stabilizer 709 is fixedly connected to the inner wall of the mounting frame 2, and the other end of the stabilizer 709 is fixedly connected to the limit piece 711.

[0037] When the splicing frame 6 is removed from the inside of the mounting frame 2, turn the wrench 702 towards the sliding post 704. This will cause the sliding post 704 to move towards the mounting frame 2 via the rotating rod 705. The sliding post 704 will then push the fixing post 712 towards the mounting frame 2, thereby moving the sliding sleeve 708 towards the mounting frame 2. This will compress the return spring 710, ensuring that the sliding sleeve 708 does not obstruct the outside of the insert block 706. At this point, the splicing frame 6 can be pulled upwards to remove it. During installation, first place the insert block 706 on the splicing frame 6 into the insert groove 714. Then, move the sliding sleeve 708 towards the mounting frame 2. Push the sleeve 708 towards the mounting frame 2, so that the insert block 706 falls into the insert groove 714. Then push the two sliding sleeves 708 on the other side, so that the insert block 706 falls into the insert groove 714. At this time, turn the wrench 702 away from the sliding post 704, so that the rotating rod 705 can drive the sliding post 704 away from the mounting frame 2. At this time, the fixing post 712 is not blocked. Under the reaction force of the return spring 710, the sliding sleeve 708 is pushed towards the splicing frame 6, so that the sliding sleeve 708 covers the joint between the splicing post 707 and the splicing frame 6, thereby completing the installation of the splicing frame 6.

[0038] The positioning mechanism 8 includes multiple recessed grooves 801. These grooves provide installation positions and prevent accidental contact or pressure on the top plate 807, which could damage its components. All recessed grooves 801 are located at the top of the splicing frame 6, away from the suspension airbag 1. Two toothed plates 802 are fixedly connected inside each recessed groove 801. Multiple mounting grooves 803 are provided inside the splicing frame 6, providing installation positions. A push spring 804 is installed inside each mounting groove 803. A limit plate 805 is slidably connected inside the mounting groove 803. A positioning post 806 is fixedly connected to the center of the limit plate 805. The push spring 804 can push the limit plate 805 to reset, thereby pushing the positioning post 806 to reset. A top plate 807 is fixedly connected to the top of the frame 807, providing an installation position. A rotating frame 808 is rotatably connected to the bottom of the top plate 807. The rotating frame 808 can engage with the toothed plate 802 to prevent the top plate 807 from moving downward. Multiple slots 809 are provided at the top of the fixed frame 3 away from the splicing frame 6. A positioning sleeve 810 is engaged inside the slot 809. One end of the push spring 804 is fixedly connected to the top of the limiting plate 805, and the other end of the push spring 804 is fixedly connected to the inner wall of the mounting groove 803. The push spring 804 is sleeved on the outside of the positioning post 806. The positioning post 806 is slidably connected inside the splicing frame 6. The top plate 807 is set inside the recessed groove 801. The rotating frame 808 engages with the toothed plate 802.

[0039] After the perch block 401 slides into the fixing frame 3, the positioning sleeve 810 prevents it from sliding along the fixing frame 3. When another set of perch blocks 401 slides into the bottom of the splicing frame 6, the positioning post 806 prevents them from sliding. When additional perch blocks 401 need to be added laterally, the positioning sleeve 810 can be removed from the slot 809, and the top plate 807 can be pulled upwards, causing the positioning post 806 to move upwards. This prevents the bottom of the positioning post 806 from obstructing the perch block 401. When the top plate 807 moves upwards, the rotating frame 808 can rotate downwards under concentrated force, allowing the rotating frame 808 to rotate downwards. The bottom of the rotating frame 808 engages with the toothed plate 802, thereby supporting the top plate 807 and preventing the positioning post 806 from falling. Without the obstruction of the positioning sleeve 810 and the positioning post 806, the installation area of ​​the fixed frame 3 and the splicing frame 6 can be expanded, allowing the perching block 401 to be added laterally. When the positioning post 806 needs to be lowered, the top plate 807 can be pulled upward and the rotating frame 808 can be pushed outward. When the top plate 807 is released, the limiting plate 805 can be moved downward under the reaction force of the pushing spring 804, allowing the positioning post 806 to penetrate the bottom of the splicing frame 6, thus preventing the perching block 401 from falling.

[0040] Working principle: When assembling the device, firstly, slide the slide bar 403 at the bottom of one perch block 401 into the slide groove 402 at the top of another perch block 401 to complete the longitudinal splicing of two perch blocks 401. Then, slide a splicing slider 405 into the interior of another splicing slide frame 404 to complete the transverse splicing of two perch blocks 401. The longitudinal and transverse splicing can achieve mutual restraint, thereby improving the stability of the splicing of multiple perch blocks 401. Then, remove the splicing frame 6 from the fixed frame 3, slide the slide groove 402 on the top perch block 401 into the bottom of the fixed frame 3, and slide another set of top perch blocks 401 into the bottom of the splicing frame 6. Finally, install the splicing frame 6 on the fixed frame 3 through the splicing mechanism 7 to complete the assembly of the device.

[0041] When assembling the perch blocks 401, firstly, the top of the pull rope 506 on the lower perch block 401 is engaged with the fixed sleeve rod 505 of the upper perch block 401 via the spring clip hook 507. The spring clip hook 507 on the top of the pull rope 506 on the uppermost perch block 401 is then engaged with the sleeve post 508 of the uppermost perch block 401. When the barrier net 504 needs to be raised, firstly, the uppermost spring clip hook 507 is detached from the sleeve post 508. At this time, the uppermost pull rope 506 is pulled upwards, thereby causing the bending strip 503 to move upwards, thus allowing passage... The fixed sleeve rod 505 drives the lower pull rope 506 to rise, which in turn drives the lower bending strip 503 to rise. At this time, the barrier net 504 can be pulled up and unfolded to cover the outside of the habitat block 401, blocking the habitat hole 406 and preventing the prawns inside the habitat block 401 from escaping. When the spring hook 507 at the bottom of the pull rope 506 moves to the sleeve post 508, the uppermost spring hook 507 can be engaged with the outside of the uppermost sleeve post 508, thereby preventing the bending strip 503 from falling and causing the barrier net 504 to retract.

[0042] When the splicing frame 6 is removed from the inside of the mounting frame 2, turn the wrench 702 towards the sliding post 704. This will cause the sliding post 704 to move towards the mounting frame 2 via the rotating rod 705. The sliding post 704 will then push the fixing post 712 towards the mounting frame 2, thereby moving the sliding sleeve 708 towards the mounting frame 2. This will compress the return spring 710, ensuring that the sliding sleeve 708 does not obstruct the outside of the insert block 706. At this point, the splicing frame 6 can be pulled upwards to remove it. During installation, first place the insert block 706 on the splicing frame 6 into the insert groove 714. Then, move the sliding sleeve 708 towards the mounting frame 2. Push the sleeve 708 towards the mounting frame 2, so that the insert block 706 falls into the insert groove 714. Then push the two sliding sleeves 708 on the other side, so that the insert block 706 falls into the insert groove 714. At this time, turn the wrench 702 away from the sliding post 704, so that the rotating rod 705 can drive the sliding post 704 to move away from the mounting frame 2. At this time, the fixing post 712 is not blocked. Under the reaction force of the return spring 710, the sliding sleeve 708 is pushed towards the splicing frame 6, so that the sliding sleeve 708 covers the joint between the splicing post 707 and the splicing frame 6, thereby completing the installation of the splicing frame 6.

[0043] After the perch block 401 slides into the fixing frame 3, the positioning sleeve 810 prevents it from sliding along the fixing frame 3. When another set of perch blocks 401 slides into the bottom of the splicing frame 6, the positioning post 806 prevents them from sliding. When additional perch blocks 401 need to be added laterally, the positioning sleeve 810 can be removed from the slot 809, and the top plate 807 can be pulled upwards, causing the positioning post 806 to move upwards. This prevents the bottom of the positioning post 806 from obstructing the perch block 401. When the top plate 807 moves upwards, the rotating frame 808 can rotate downwards under concentrated force, allowing the rotating frame 808 to rotate downwards. The bottom of the rotating frame 808 engages with the toothed plate 802, thereby supporting the top plate 807 and preventing the positioning post 806 from falling. Without the obstruction of the positioning sleeve 810 and the positioning post 806, the installation area of ​​the fixed frame 3 and the splicing frame 6 can be expanded, allowing the perching block 401 to be added laterally. When the positioning post 806 needs to be lowered, the top plate 807 can be pulled upward and the rotating frame 808 can be pushed outward. When the top plate 807 is released, the limiting plate 805 can be moved downward under the reaction force of the pushing spring 804, allowing the positioning post 806 to penetrate the bottom of the splicing frame 6, thus preventing the perching block 401 from falling.
