Description

Technical Field

[0001] This utility model relates to the field of fish and shrimp polyculture technology, specifically to a fish and shrimp polyculture isolation net. Background Technology

[0002] Pond farming of fish and shrimp is an important part of my country's aquaculture industry. In recent years, due to the deterioration of the farming environment and the continuous degradation of various resources, diseases have occurred frequently, and the success rate of farming has declined year after year. The main problem with polyculture of fish and shrimp is that if the number of fish in the polyculture is too small, it will not play a role in the biological control of shrimp diseases.

[0003] Currently, the isolation nets used in fish and shrimp polyculture ponds need to be buried 30 centimeters into the pond mud, with the top end protruding more than 50 centimeters above the water surface, and fixed at intervals of three to five meters, in order to achieve better sealing and reduce organic pollution in the pond.

[0004] To overcome the above-mentioned defects, the prior art (application number: CN203072659U, Chinese patent with application date of 2013-03-05) discloses a fish and shrimp polyculture isolation net, which relates to the field of aquatic animal breeding technology. It includes a magnetic dense net isolation net, a magnetic sparse net attachment net, and a magnetic dense net attachment net. When it is necessary to clean the isolation net, the net rope can be untied and the magnet can be pulled to retract the attachment net. When installing the magnetic attachment net, the magnet of the attachment net is aligned with the magnet of the isolation net and the top of the attachment net is fixed to realize the installation of the attachment net. This improves work efficiency and reduces unnecessary losses caused when changing fish and shrimp ponds.

[0005] While existing technologies can solve the above problems, they are too complicated for fixing operations. When dealing with large bodies of water, manual work requires repeated fixing of each net, which is a waste of time and manpower. Moreover, the fixing effect on the two sides of the fishing net is not stable enough. If large gaps appear on the two sides of the fishing net, the isolation effect will fail. Utility Model Content

[0006] The purpose of this utility model is to provide a fish and shrimp polyculture isolation net to solve the problems mentioned in the background art, such as the overly complicated operation when fixing is required, the need for repeated fixing of each net in large water areas, which is a waste of time and manpower, and the unstable fixing effect on the two sides of the net. If a large gap appears on the two sides of the net, the isolation effect will fail.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fish and shrimp polyculture isolation net, comprising floats installed on the outer surface of the isolation net, the floats being equidistantly installed on the outer surface of the isolation net, an upper line installed inside the floats, the upper line being fixedly connected to the isolation net, a sliding frame installed above the isolation net, and a meshing transmission mechanism for sliding a connecting plate up and down installed inside the sliding frame, the meshing transmission mechanism including a rotating frame, a rotating disk installed inside the rotating frame, a transmission gear installed at the other end of the rotating disk, a meshing gear rod installed on the right side of the transmission gear, a connecting plate installed at the lower end of the meshing gear rod, and the connecting plate being fixedly connected to the meshing gear rod;

[0008] A rotating seat is installed above the isolation net, and a rotating sliding mechanism for raising and lowering the counterweight is installed inside the rotating seat.

[0009] Furthermore, the rotating sliding mechanism includes a rotating seat, and a turntable is mounted on the outer surface of the rotating seat. The turntable controls the internal rotation of the rotating seat. A shrinking wire assembly is mounted on the outer surface of the rotating seat, and a limit frame is mounted on the outer surface of the shrinking wire assembly.

[0010] Furthermore, a counterweight is installed at the end of the shrinkage line assembly, and the internal hollow position of the limiting frame is consistent with the diameter of the counterweight.

[0011] Furthermore, sliding frames are installed on the outer surfaces of both ends of the connecting plate, and a second inner groove is provided on the back of the sliding frame. The sliding trajectory of the connecting plate corresponds to the fitting frame, and a first inner groove is provided on the surface of the fitting frame.

[0012] Furthermore, the transmission gear and the rotating disk are designed as a single unit, and the transmission gear and the rotating disk are mounted inside the rotating frame. Moreover, the outer surface of the meshing gear rod and the outer surface of the transmission gear are in contact to form a meshing structure.

[0013] Furthermore, the outer surface of the connecting plate contacts the inner surface of the second inner groove to form a sliding structure, and the outer surface of the connecting plate contacts the inner surface of the first inner groove to form a sliding structure. Moreover, the rotating disk is fixedly connected to the side of the meshing gear rod through the outer surface of the transmission gear to form a transmission mechanism.

[0014] Furthermore, the turntable forms a transmission structure by contacting the outer surface of the rotating seat with the outer surface of the shrinking wire assembly, and the shrinking wire assembly is fixedly connected to the counterweight. Moreover, the interior of the limiting frame contacts the outer surface of the counterweight to form a sliding structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When the bottom middle section needs to be fixed after the two ends are fixed, the rotating disk rotates along the inside of the rotating frame. Since the transmission gear is fixedly connected to the rotating disk, the transmission gear drives the meshing gear rod to move downward as it rotates. The meshing gear rod drives the connecting plate, which is also fixedly installed, to move downward. The connecting plate slides vertically along the inside of the sliding frame until the fixing work is completed. Moreover, multiple sets of sliding frames are distributed along the lower end of the connecting plate to fix a larger area. This design saves manpower and fixing time.

[0016] Furthermore, when the fishing net is launched into the water, the two ends of the fishing net need to be fixed to divide the area. After placing the two sides of the fishing net in the appropriate position, the turntable is rotated to make the turntable control the rotating seat to rotate. The rotating seat controls the extension of the shrink line group to continuously stretch the outer shrink line group. The stretching of the shrink line group causes the counterweight to move down along the limit frame until it touches the bottom to complete the fixing work. This design prevents the two ends of the fishing net from having too large a gap, which would cause the isolation to fail.

[0017] Furthermore, as the connecting plate slides downward along the second inner groove, it slides vertically and horizontally and enters the interior of the fitting frame. The fitting frame is fixed to the lower end of the isolation net, thus ensuring the installation stability of the middle section of the isolation net. Attached Figure Description

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-6 The present invention provides the following technical solution: a fish and shrimp mixed culture isolation net, including an isolation net 1, a float 2, and a second inner tank 17.

[0027] A float 2 is installed on the outer surface of the isolation net 1, and the floats 2 are equidistantly installed on the outer surface of the isolation net 1. An upper wire 8 is installed inside the float 2, and the upper wire 8 is fixedly connected to the isolation net 1. A sliding frame 9 is installed above the isolation net 1, and a meshing transmission mechanism for sliding the connecting plate 10 up and down is installed inside the sliding frame 9. The meshing transmission mechanism includes a rotating frame 11, and a rotating disk 14 is installed inside the rotating frame 11. A transmission gear 13 is installed at the other end of the rotating disk 14, and a meshing gear rod 12 is installed on the right side of the transmission gear 13. A connecting plate 10 is installed at the lower end of the meshing gear rod 12, and the connecting plate 10 and the meshing gear rod 12 are fixedly connected.

[0028] A rotating seat 4 is installed above the isolation net 1, and a rotating sliding mechanism for raising and lowering the counterweight 7 is installed inside the rotating seat 4.

[0029] like Figure 2 , Figure 3 , Figure 6 The technical solution shown discloses the following to address the problem of gaps easily generated when fixing the two sides of the fishing net: a rotating sliding mechanism includes a rotating seat 4, and a turntable 3 is installed on the outer surface of the rotating seat 4. The turntable 3 controls the internal rotation of the rotating seat 4. A shrink line group 6 is installed on the outer surface of the rotating seat 4, and a limit frame 5 is installed on the outer surface of the shrink line group 6. A counterweight 7 is installed at the end of the shrink line group 6, and the internal hollow position of the limit frame 5 is consistent with the diameter of the counterweight 7. The turntable 3 forms a transmission structure by contacting the outer surface of the rotating seat 4 with the outer surface of the shrink line group 6. The shrink line group 6 and the counterweight 7 are fixedly connected, and the internal contact of the limit frame 5 with the outer surface of the counterweight 7 forms a sliding structure.

[0030] When isolation is required, the movable isolation net 1 is used to isolate the pond diagonally, creating a triangular area. The left and right sides of the isolation net 1 are then fixed in place. Once inside the pond, the floats 2 distributed on the surface of the isolation net 1 generate buoyancy, preventing the net from sinking completely. After fixing both ends, the turntable 3 is rotated, controlling the connected rotating seat 4. The rotation of the rotating seat 4 causes the shrinkage line group 6, which is wound around the outer surface, to shrink. The shrinkage line group 6 expands and contracts with the rotation of the turntable 3. Multiple sets of limit frames 5 installed on the outer surface of the shrinkage line group 6 ensure the stability of the movement. The counterweight 7 fixed at the end of the shrinkage line group 6 corresponds to the hollow position of the limit frame 5 and passes through its interior. The combination of the turntable 3 and rotating seat 4, as well as the shrinkage line group 6 and counterweight 7 at both ends of the isolation net 1, achieves the fixing strength of both ends of the isolation net 1 without creating large gaps, making the isolation effect more airtight.

[0031] like Figure 1 , Figure 5 , Figure 4 The technical solution shown herein, in order to solve the problem that fixed interval work is too time-consuming and inconvenient to operate, discloses that: sliding frames 9 are installed on the outer surfaces of both ends of the connecting plate 10, and a second inner groove 17 is opened on the back of the sliding frame 9; the sliding trajectory of the connecting plate 10 corresponds to that of the fitting frame 15, and a first inner groove 16 is opened on the surface of the fitting frame 15; the transmission gear 13 and the rotating disk 14 are designed as an integral unit, and the transmission gear 13 is rotatably installed inside the rotating frame 11; the outer surface of the meshing gear rod 12 contacts the outer surface of the transmission gear 13 to form a meshing structure; the outer surface of the connecting plate 10 contacts the inner surface of the second inner groove 17 to form a sliding structure; the outer surface of the connecting plate 10 contacts the inner surface of the first inner groove 16 to form a sliding structure; and the rotating disk 14 is fixedly connected to the side of the meshing gear rod 12 through the outer surface of the transmission gear 13 to form a transmission mechanism.

[0032] When the sealing work at both ends of the isolation net 1 is completed, it enters the breeding pond and rotates the rotating disk 14 along the inside of the rotating frame 11. Since the transmission gear 13 and the rotating disk 14 are integrated, the transmission gear 13 rotates in a circle along the inside of the rotating frame 11. The rotation of the transmission gear 13 drives the meshing gear rod 12 fixed on the side to move up and down. The transmission gear 13 drives the connecting plate 10 fixedly connected to the lower end of the meshing gear rod 12 downward in sync. The connecting plate 10 slides along the inside of the sliding frame 9 with the transmission. The connecting plate 10 passes through the second inner groove 17 opened on the back of the sliding frame 9. The connecting plate 10 slides downward along the second inner groove 17 and finally enters the interior of the fitting frame 15 fixed at the lower end of the isolation net 1. It enters the first inner groove 16 opened on the surface of the fitting frame 15 to complete the nesting installation and finally inserts into the soil of the breeding pond. The fixed upper bars 8 distributed on the surface of the isolation net 1 make the surface of the isolation net 1 more solid and durable.
