Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a large yellow croaker farming cage that utilizes sea urchin cleaning netting. Background Technology

[0002] Aquaculture netting is an indispensable component of modern marine aquaculture. It not only provides fish with a space to grow but also protects them from predators. With the development of aquaculture technology, netting materials and designs are constantly improving to adapt to the ever-changing marine environment and increase aquaculture efficiency. However, this also presents many challenges. Netting maintenance includes regular inspection and cleaning to remove organisms and repair damage.

[0003] Excessive biological attachment reduces the strength and durability of netting, affects water exchange, and consequently impacts fish growth and health. Therefore, biological control methods (mixed aquaculture) have been explored, which are environmentally friendly and sustainable. However, relying solely on sea urchins to remove biological attachments is very slow, and the inner netting walls of the fish farms are not effectively cleaned. Therefore, it is necessary to propose a method for using sea urchins to clean the netting in large yellow croaker aquaculture cages. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a large yellow croaker aquaculture cage that utilizes sea urchin cleaning netting.

[0005] The technical solution adopted by this invention to solve its technical problem is: a large yellow croaker aquaculture cage using sea urchin cleaning netting, including a water tank, with slots opened at the upper ends of the two inner side walls of the water tank, a collection box fixedly installed in the middle of the bottom end of the water tank, two rotating rods rotatably connected to the two outer walls of the collection box, and two U-shaped algae rotating plates fixedly connected to the walls of the two rotating rods at both ends, with mounting blocks fixedly connected to the bottom edges of the two algae rotating plates, and sliding rods fixedly connected to the outer walls of the two mounting blocks near the inner wall of the water tank, and arc-shaped grooves opened on the inner side walls of both ends of the water tank near the sliding rods, with springs fixedly connected between the inner walls of the arc-shaped grooves and the sliding rods;

[0006] Both of the two sockets have insert blocks snapped into their inner walls. A connecting frame is fixedly connected between the two insert blocks. An inner mesh frame is fixedly connected to the bottom of the connecting frame. Two through holes are opened at the upper end of one inner side wall of the inner mesh frame. Two sliding grooves are opened near the lower end of the through holes on both inner side walls of the inner mesh frame. Sliding blocks are slidably connected to the inner walls of the two sliding grooves. Connecting rods are fixedly connected to the outer walls of the two sliding blocks. Several U-shaped cleaning rods are fixedly connected between the two connecting rods. Several toothed grooves are opened on the outer wall of one of the connecting rods near the two through holes. A transmission gear is rotatably connected between the two inner side walls of the two through holes through a rotating shaft.

[0007] One of the inserts has a connecting block fixedly connected to its bottom end near the transmission gear. A receiving groove is provided on one side of the inner wall of the connecting block. Two lifting grooves are provided on the inner side wall of each receiving groove. Two lifting blocks are slidably connected to the inner walls of each of the two lifting grooves. A rack plate is fixedly connected to the outer wall of each of the two lifting blocks. Two locking rods are slidably connected through the bottom end of the receiving groove. Limiting blocks are fixedly connected to the rod walls of each of the two locking rods within the receiving groove. A notch is provided on one side of the bottom end of each of the two locking rods.

[0008] Specifically, the water tank is fixedly connected to support legs at the four corners of its bottom edge.

[0009] Specifically, an inlet pipe is embedded in one side wall of the water tank, and an outlet pipe is embedded in the other side of the bottom of the water tank.

[0010] Specifically, both of the algae rotating plates have several recessed grooves on their surfaces, and both of the sliders are engaged in the grooves.

[0011] Specifically, the two sliding rods at both ends are both engaged in the arc-shaped groove.

[0012] Specifically, the two rack plates, the transmission gear, and the several tooth grooves are all meshing connections.

[0013] Specifically, both notches are located on opposite sidewalls of the lever, and both notches are engaged with the rotating lever.

[0014] The beneficial effects of this invention are:

[0015] (1) The large yellow croaker aquaculture cage using sea urchins to clean the netting described in this invention reduces the cost of manual cleaning by classifying and mixing sea urchins and large yellow croakers for aquaculture, and increases the variety of aquaculture organisms, which is in line with green, healthy and stable sustainable aquaculture.

[0016] (2) The large yellow croaker aquaculture cage using sea urchin cleaning netting described in this invention uses sea urchins crawling on an algae rotating plate covered with algae. At this time, the algae rotating plate rotates downward under force. Through the linkage and cooperation of the installation block, sliding rod, spring, clamp, notch, connecting block, receiving groove, rack plate, transmission gear, several toothed grooves, connecting rod, and several cleaning rods, several cleaning rods can be driven to clean the inner side wall of the inner net frame, thereby improving the cleaning efficiency of the inner net frame.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-8As shown, the large yellow croaker aquaculture cage using sea urchin cleaning netting of the present invention includes a water tank 1. The upper ends of the two inner side walls of the water tank 1 are provided with insertion ports 101. A collection box 12 is fixedly installed in the middle of the bottom end of the water tank 1. Two rotating rods 13 are rotatably connected to the two outer walls of the collection box 12. U-shaped algae rotating plates 14 are fixedly connected to the walls of the two rotating rods 13 at both ends. Mounting blocks 15 are fixedly connected to the bottom edges of the two algae rotating plates 14. Sliding rods 16 are fixedly connected to the outer walls of the two mounting blocks 15 near the inner wall of the water tank 1. Arc-shaped grooves 103 are provided on the inner side walls of both ends of the water tank 1 near the sliding rods 16, and springs 17 are fixedly connected between the inner walls of the arc-shaped grooves 103 and the sliding rods 16.

[0029] Both sockets 101 have insert blocks 22 snapped into their inner walls. A connecting frame 21 is fixedly connected between the two insert blocks 22. An inner mesh frame 2 is fixedly connected to the bottom of the connecting frame 21. Two through holes 201 are opened at the upper end of one inner side wall of the inner mesh frame 2. Two sliding grooves 202 are opened at the lower ends of the two inner side walls of the inner mesh frame 2 near the through holes 201. Sliding sliders 23 are slidably connected to the inner walls of the two sliding grooves 202. Connecting rods 24 are fixedly connected to the outer walls of the two sliding sliders 23. Several U-shaped cleaning rods 25 are fixedly connected between the two connecting rods 24. Several toothed grooves 203 are opened on the outer wall of one of the connecting rods 24 near the two through holes 201. A transmission gear 26 is rotatably connected between the two inner side walls of the two through holes 201 through a rotating shaft.

[0030] One of the inserts 22 has a connecting block 3 fixedly connected to the bottom end near the transmission gear 26. The inner wall of the connecting block 3 has a receiving groove 301. The inner wall of the receiving groove 301 has two lifting grooves 302. The inner walls of the two lifting grooves 302 are slidably connected to two lifting blocks 31. The outer walls of the two lifting blocks 31 are fixedly connected to rack plates 32. The bottom end of the receiving groove 301 has two locking rods 33 slidably connected through it. The rod walls of the two locking rods 33 are located in the receiving groove 301 and are fixedly connected to limit blocks 34. The bottom end of the two locking rods 33 has a notch 303 on one side.

[0031] Specifically, support legs 11 are fixedly connected to the four corners of the bottom of the water tank 1, and several support legs 11 can support the water tank 1.

[0032] Specifically, water tank 1 has an inlet pipe embedded on one side wall and an outlet pipe embedded on the other side of the bottom. Water solution can be added to water tank 1 through the inlet pipe and wastewater inside water tank 1 can be discharged through the outlet pipe.

[0033] Specifically, each of the two algae rotating plates 14 has several recessed grooves 102 on its surface, and the two sliders 23 are both locked in the grooves 202. Algae can grow in the grooves 102, and the connecting rod 24 slides along the grooves 202 through the sliders 23.

[0034] Specifically, the two slide rods 16 at both ends are locked in the arc-shaped groove 103, and the algae rotating plate 14 compresses the spring 17 along the arc-shaped groove 103 through the two slide rods 16.

[0035] Specifically, the two rack plates 32, the transmission gear 26, and the several tooth grooves 203 are all meshed. The rack plate 32 slides upward to mesh with the transmission gear 26, and the transmission gear 26 drives the connecting rod 24 to move upward by meshing with the several tooth grooves 203.

[0036] Specifically, the opening ends of the two notches 303 are both opened on the opposite side walls of the locking rod 33, and the two notches 303 are engaged with the rotating rod 13. The locking rod 33 can be engaged with the rod wall of the rotating rod 13 through the notches 303 and abut against the rotating rod 13.

[0037] In use, first place the large yellow croaker inside the inner mesh frame 2, then place the sea urchin between the inner mesh frame 2 and the water tank 1, and then place the algae in the groove 102 on the algae rotating plate 14. Then, add water solution to the water tank 1 through the inlet pipe. Over time, a large amount of algae will adhere to both the inner and outer walls of the inner mesh frame 2. Some sea urchins will clean the algae, while others will clean the algae placed on the algae rotating plate 14. At this time, the algae rotating plate 14 will move downwards under pressure, causing the mounting block 15 to rotate downwards. The mounting block 15 will compress the spring 17 along the arc groove 103 via the slide rod 16. At this time, the algae rotating plate 14 will drive the locking rod 33. Slide upwards against the rack plate 32, causing the rack plate 32 to move upwards. The rack plate 32 slides upwards and engages with the transmission gear 26. The transmission gear 26 engages with several tooth grooves 203 to drive the connecting rod 24 upwards. The connecting rod 24 will drive several cleaning rods 25 to slide upwards along the inner wall of the inner mesh frame 2 for cleaning. The algae attached to the inner surface of the inner mesh frame 2 will slowly fall into the collection box 12. After the algae on the algae rotating plate 14 has finished eating, the sea urchin will crawl into the collection box 12. At this time, the algae rotating plate 14 will be reset by the spring 17. Similarly, it will drive several cleaning rods 25 to slide along the inner wall of the inner mesh frame 2 for cleaning. The reciprocating sliding of several cleaning rods 25 can effectively clean the inner wall of the inner mesh frame 2.
