[0002] Aquatic products are a general term for aquatic animal and plant products produced by marine and freshwater fisheries and their processed products. Aquatic products have become a "severely affected area" for food safety. Foodborne parasitic diseases caused by aquatic products have been reported frequently. Generally, a breeding pond is required in the breeding process of aquatic products.

[0003] A Chinese patent with the authorization publication number CN209089716U discloses a healthy breeding pond for aquatic product breeding, in which feed residues and excrement are discharged from the outlet pipe through the flow of water, thereby ensuring the environment in the breeding pond and reducing the disease rate of aquatic products.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 9A breeding pond for aquatic product breeding includes a base 1, a breeding pond body 2 is fixedly installed on the upper end surface of the base 1, a support column 3 is arranged on the outer side of the breeding pond body 2, the support column 3 is fixedly connected to the base 1, two groups of support columns 3 are arranged and are symmetrically arranged, a motor 4 is arranged on the upper side of the breeding pond body 2, and the two groups of support columns 3 are fixedly connected to the motor 4, a net covering mechanism is arranged on the outer side of the breeding pond body 2, and multiple groups of fixing mechanisms 1 and 2 are arranged on the lower side of the net covering mechanism, and the net covering mechanism includes the end of the lower output shaft of the motor 4 A rotating shaft 5 is fixedly installed, and a guide ring 9 is arranged on the upper side of the outer surface of the breeding pond body 2, and the guide ring 9 is fixedly connected to the two groups of support columns 3. A traction plate 6 is fixedly installed on the outer surface of the rotating shaft 5, and a slip ring 10 is fixedly installed on the inner wall of the traction plate 6, and the slip ring 10 is slidably connected to the guide ring 9. An inner groove 7 is provided inside the support column 3, and a winding shaft 37 is rotatably connected inside the inner groove 7. A sunshade net 8 is wound around the outer surface of the winding shaft 37, and one end of the sunshade net 8 is fixedly connected to the traction plate 6, and a counterweight bar 11 is fixedly installed on the lower end of the sunshade net 8.

[0033] When there is excess sunlight outside and the breeding pond body 2 needs to be shaded, the motor 4 is started to make the output shaft of the motor 4 carry the rotating shaft 5 to rotate. The rotating shaft 5 is fixedly connected to the two groups of traction plates 6, so the two groups of traction plates 6 are synchronously deflected and displaced. When the traction plates 6 are displaced, the sunshade net 8 will be pulled out from the inside of the inner groove 7. The sunshade net 8 will cover the breeding pond body 2 as the traction plates 6 are displaced. When shading is not needed, the output shaft of the motor 4 drives the rotating shaft 5 to reverse. At this time, the winding shaft 37 in the inner groove 7 will rotate in the opposite direction under the action of the winding spring 38, thereby cooperating with the traction plates 6 to rewind the sunshade net 8 into the inner support for storage.

[0034] A coil spring 38 is sleeved on the lower side of the outer surface of the winding shaft 37 , one end of the coil spring 38 is fixedly connected to the winding shaft 37 , and a fixing block 39 is fixedly installed on the other end of the winding shaft 37 , and the fixing block 39 is fixedly connected to the inner wall of the inner groove 7 .

[0035] In actual aquaculture, many breeding ponds are set up in open-air environments. Fish seedlings have strict requirements on water temperature, especially in the high temperature period in summer, direct sunlight will cause the water temperature in the pond to rise rapidly, which may cause large-scale death of fish seedlings. Therefore, under hot weather conditions, it is usually necessary to lay a sunshade net 8 on the breeding pond to reduce the water temperature. However, the current method of manually laying the sunshade net 8 is not only time-consuming and labor-intensive, but also the laying structure is not stable enough, which easily leads to poor shading effect. Therefore, this solution sets a covering net mechanism and uses a motor 4 to drive to realize the automatic laying of the sunshade net 8 above the breeding pond, which completely gets rid of the traditional manual operation. This method not only significantly improves work efficiency and reduces labor costs, but also ensures the stability and covering quality of the sunshade net 8, effectively maintains a suitable water temperature environment in the breeding pond, and ensures the healthy growth of fish fry. At the same time, this solution also firmly fixes the bottom of the sunshade net 8 by designing fixing mechanism 1 and fixing mechanism 2, effectively preventing the sunshade net 8 from being overturned in windy weather, significantly improving the stability and reliability of the sunshade net 8, ensuring the stability of the water temperature in the breeding pond during high temperature seasons, providing a safer and more suitable growth environment for fish fry, while reducing labor maintenance costs and improving breeding efficiency.

[0036] The fixing mechanism 1 includes a rack 12 fixedly installed at the lower end of the traction plate 6, a slide groove 14 is provided inside the base 1, and a threaded rod 15 is rotatably connected inside the slide groove 14. A gear 13 is provided on the outside of the base 1, and one end of the threaded rod 15 extends to the outside of the slide groove 14 and is fixedly connected to the gear 13. A threaded sleeve 16 is spirally connected to one side of the outer surface of the threaded rod 15, and a transmission rod 17 is fixedly installed on the upper end of the threaded sleeve 16. A threaded sleeve 2 18 is spirally connected to the other side of the outer surface of the threaded rod 15, and the upper end of the threaded sleeve 2 18 is fixedly installed. A transmission rod 2 19 is installed, and both the transmission rod 17 and the transmission rod 2 19 are slidably connected to the slide groove 14, and a central axis 22 is rotatably connected between the transmission rod 17 and the transmission rod 2 19, a clamping plate 21 is fixedly installed on the upper end of the transmission rod 17, and a clamping plate 20 is fixedly installed on the upper end of the transmission rod 2 19, and the clamping plate 1 20 and the clamping plate 21 are respectively arranged on both sides of the counterweight bar 11, and a notch 23 is opened inside the clamping plate 1 20 and the clamping plate 21, and a fixed shaft 24 is fixedly installed inside the notch 23, and a roller 25 is rotatably connected to the outer surface of the fixed shaft 24.

[0037] When the traction plate 6 deflects and moves, it will carry the rack 12 to move. When the rack 12 moves to the gear 13, it will mesh with the gear 13, thereby causing the gear 13 to rotate. The gear 13 synchronously drives the threaded rod 15 to rotate. The thread groove on the outer surface of the threaded rod 15 is a bidirectional thread groove. Therefore, the threaded sleeve 16 and the threaded sleeve 2 18 connected by the spiral transmission on the outer surface of the threaded rod 15 will move in opposite directions. The threaded sleeve 16 carries the transmission rod 17 to move, and the threaded sleeve 2 18 carries the transmission rod 2 19 to move. The transmission rod 17 A central axis 22 is rotatably connected to the transmission rod 19, and a scissor-like structure is formed between the central axis 22, the transmission rod 17 and the transmission rod 2 19. Therefore, the splint 1 20 at the upper end of the transmission rod 17 and the splint 21 at the upper end of the transmission rod 2 19 will move obliquely upward, and the central axis 22 will move upward synchronously. The splint 1 20 and the splint 21 will clamp the sunshade net 8 and rely on the roller 25 to limit the sunshade net 8. The setting of the roller 25 can ensure that the sunshade net 8 is limited while continuing to perform the covering and shading task.

[0038] The fixing mechanism 2 includes a wedge block 26 fixedly installed at both ends of the central axis 22, two groups of wedge blocks 2 30 are symmetrically arranged on both sides of the wedge block 26, a transmission column 29 is fixedly installed on one end of the wedge block 20, and a sleeve 28 is slidably connected to the other end of the transmission column 29, and support rods 27 are arranged on both sides of the wedge block 26, and the support rods 27 are arranged in an L shape. The sleeve 28 is fixedly connected to the support rod 27, and a spring 31 is fixedly installed between the sleeve 28 and the wedge block 20, and the spring 31 is sleeved on the transmission column 29. On the outer surface of the moving column 29, a horizontal axis 2 34 is fixedly installed at the end of the horizontal rod of the support rod 27, a slider 32 is slidably connected to one end surface of the wedge block 20, and a horizontal axis 1 33 is fixedly installed on the other end of the slider 32. A connecting rod 35 is rotatably connected to the outer surface of the horizontal axis 2 34, and one end of the connecting rod 35 is rotatably connected to the horizontal axis 1 33. A splint 3 36 is provided on the upper side of the wedge block 1 26, and the other end of the connecting rod 35 is fixedly connected to the splint 3 36. Two groups of connecting rods 35 are provided, and are symmetrically arranged.

[0039] When the middle axis 22 rises, it will carry the wedge block 1 26 up. The rising wedge block 1 26 will contact with two groups of symmetrical wedge blocks 2 30 and slide against each other, so that the two groups of wedge blocks 2 30 will be displaced to both sides. The wedge block 2 30 will drive the horizontal axis 1 33 to be displaced to both sides through the slider 32. The horizontal axis 1 33 is rotatably connected to one end of the connecting rod 35, so the connecting rod 35 will deflect around the horizontal axis 2 34, and the splint three 36 at the other end of the horizontal axis 2 34 will be displaced toward the sunshade net 8. The two groups of splints three 36 will be displaced toward the sunshade net 8 synchronously. The roller 25 is synchronously provided on the inner side of the splint three 36, and the sunshade net 8 is limited by the roller 25. The sliding connection between the slider 32 and the wedge block 2 30 can offset the conflict between the lateral displacement of the wedge block 2 30 and the circular motion of the connecting rod 35.

[0040] Method of use: When there is excessive sunlight outside and the main body 2 of the breeding pond needs to be shaded, the motor 4 is started to make the output shaft of the motor 4 carry the rotating shaft 5 to rotate, and the rotating shaft 5 is fixedly connected to the two groups of traction plates 6, so the two groups of traction plates 6 are synchronously deflected and displaced. When the traction plates 6 are displaced, the sunshade net 8 will be pulled out from the inside of the inner groove 7, and the sunshade net 8 will cover the main body 2 of the breeding pond as the traction plates 6 are displaced. When shading is not needed, the output shaft of the motor 4 drives the rotating shaft 5 to reverse, and at this time, the reeling shaft 37 in the inner groove 7 will rotate in the opposite direction under the action of the coil spring 38, so as to cooperate with the traction plates 6 to reel the sunshade net 8 into the inner support for storage;

[0041] When the traction plate 6 deflects and moves, it will carry the rack 12 to move. When the rack 12 moves to the gear 13, it will mesh with the gear 13, thereby causing the gear 13 to rotate. The gear 13 synchronously drives the threaded rod 15 to rotate. The thread groove on the outer surface of the threaded rod 15 is a bidirectional thread groove. Therefore, the threaded sleeve 16 and the threaded sleeve 2 18 connected by the spiral transmission on the outer surface of the threaded rod 15 will move in opposite directions. The threaded sleeve 16 carries the transmission rod 17 to move, and the threaded sleeve 2 18 carries the transmission rod 2 19 to move. The transmission rod 17 A central axis 22 is rotatably connected to the transmission rod 19, and a scissor-like structure is formed between the central axis 22, the transmission rod 17 and the transmission rod 19. Therefore, the clamping plate 1 20 at the upper end of the transmission rod 17 and the clamping plate 21 at the upper end of the transmission rod 19 will move obliquely upward, and the central axis 22 will rise synchronously. The clamping plate 1 20 and the clamping plate 21 will clamp the sunshade net 8, and the sunshade net 8 is limited by the roller 25. The setting of the roller 25 can ensure that the sunshade net 8 is limited while continuing to cover the sunshade task;

[0042] When the middle axis 22 rises, it will carry the wedge block 1 26 up. The rising wedge block 1 26 will contact with two groups of symmetrical wedge blocks 2 30 and slide against each other, so that the two groups of wedge blocks 2 30 will be displaced to both sides. The wedge block 2 30 will drive the horizontal axis 1 33 to be displaced to both sides through the slider 32. The horizontal axis 1 33 is rotatably connected to one end of the connecting rod 35, so the connecting rod 35 will deflect around the horizontal axis 2 34, and the splint three 36 at the other end of the horizontal axis 2 34 will be displaced toward the sunshade net 8. The two groups of splints three 36 will be displaced toward the sunshade net 8 synchronously. The roller 25 is synchronously provided on the inner side of the splint three 36, and the sunshade net 8 is limited by the roller 25. The sliding connection between the slider 32 and the wedge block 2 30 can offset the conflict between the lateral displacement of the wedge block 2 30 and the circular motion of the connecting rod 35.

[0043] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
