Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a high-efficiency protection method and equipment for river crab seedling breeding ponds. Background Art

[0002] During the breeding process of river crab seedlings, breeding ponds face a variety of problems that seriously affect the survival rate and growth and development of river crab seedlings. On the one hand, natural enemies such as birds frequently enter the breeding ponds to prey on river crab seedlings, causing huge economic losses to farmers. On the other hand, river crab seedlings are also very easy to escape from the breeding ponds during the breeding process. Therefore, protective equipment is needed to prevent the escape of river crabs and prevent other natural enemies from entering the breeding ponds and affecting the growth of river crabs. The existing protective structures for river crab breeding ponds generally only use protective films. The protective films are fixed to vertical rods with iron wires, and the vertical rods are then inserted into the pond bank. This protective device has a simple structure and low cost of use. However, this protective structure can only prevent river crabs from escaping from the breeding ponds, and cannot effectively prevent natural enemies such as birds from entering the breeding ponds and affecting the growth of river crabs. The protective effect is single and poor, which makes it difficult to meet the needs of efficient breeding of river crab seedlings. Summary of the Invention

[0031] The front side of the rotating rod 23 passes through the mounting frame 22 and is connected to a rotating disc 27. The rotating disc 27 is connected to a rotating square rod 29. A screwing block 30 is slidably connected to the rotating square rod 29. The screwing block 30 is connected to a limiting rod 31. The mounting frame 22 is provided with a limiting hole 32. The limiting rod 31 cooperates with the limiting hole 32. The limiting rod 31 can be inserted into the limiting hole 32, thereby restricting the rotation of the screwing block 30. A spring 28 is sleeved on the rotating square rod 29. Both ends of the spring 28 are respectively connected to the rotating disc 27 and the screwing block 30. Through the spring 28, the limiting rod 31 can be stably inserted into the limiting hole 32 usually, improving the limiting effect on the screwing block 30.

[0032] A fixing rod 9 is connected to the pond bank 1. The fixing rod 9 is connected to a continuous bird repeller 12 and a monitoring camera assembly 10. An intermittent bird repeller 7 is connected to the pond bank 1. The intermittent bird repeller 7 is arranged outside the anti-escape plastic 5.

[0034] An efficient protection method for crab fry breeding ponds includes the following steps.

[0035] S1. Install the protection equipment as claimed in any one of claims 1-8.

[0036] S2. Conduct regular inspections. The breeding personnel conduct inspections on the breeding pond once in the morning and once in the evening every day to check whether the protection equipment is in good condition. At the same time, observe the activities and feeding conditions of the crab fry, and promptly discover abnormal situations and take corresponding measures.

[0037] S3. Optimize the breeding environment. Regularly change the water in the breeding pond, change the water once every 10-12 days, and the amount of water changed each time is 20-30% of the total amount of water in the breeding pond.

[0038] S4. Prevent natural enemies. Sprinkle snake repellent powder and rodent control agents around the breeding pond to prevent snakes and rodents from entering the breeding pond. At the same time, clean the weeds and sundries around the breeding pond to reduce the hiding places of snakes and rodents.

[0039] The following describes the installation of the protective equipment. When installing, first dig a groove with a depth of 20 cm on the pond embankment 1, and then lay a black plastic film 4 on the inclined slope 2, so that the upper side of the black plastic film 4 is located in the dug groove. Then lay a mesh cloth 3 on the upper side of the black plastic film 4, so that the upper side of the mesh cloth 3 is also located in the dug groove. Cover the lower ends of the black plastic film 4 and the mesh cloth 3 with soil, and then insert the inserting rod 6 into the groove. When the inserting rod 6 is inserted into the groove, it passes through the black plastic film 4 and the mesh cloth 3. Then surround the anti-escape plastic 5 inside the inserting rod 6, so that the bottom of the anti-escape plastic 5 is located in the groove. Then surround the tensioning rope 14, and the tensioning rope 14 is located on the upper side of the anti-escape plastic 5. Then roll up the upper end of the anti-escape plastic 5 outside the tensioning rope 14, pass a steel wire through the anti-escape plastic 5 and then tie the anti-escape plastic 5 to the inserting rod 6, as Figure 1 shown, to complete the connection between the anti-escape plastic 5 and the inserting rod 6. Then fill the groove with backfill soil and compact the backfill soil;

[0040] Then install the anti-bird device. Two sets of installation rollers 15 and four installation rods 11 are in a group. When the anti-bird rope 13 is not pulled out, the hanging rings 24 at both ends of the anti-bird rope 13 are respectively stuck into the hooks 16 of the two sets of installation rollers 15, and the sealing plate 17 slides out of the installation roller 15 to close the opening of the hook 16, as Figure 2 shown. At this time, the anti-bird rope 13 cannot be separated from the installation roller 15, and at this time, under the action of the spring 28, the limiting rod 31 also inserts into the limiting hole 32, so that the rotating rod 23 cannot rotate, and the sealing plate 17 can stably close the opening of the hook 16, and the anti-bird rope 13 can be wound up on one of the installation rollers 15 when not in use; when installing, first install one of the installation rollers 15 on the right installation rod 11, and align the convex block 26 with the convex chute 25 to complete the snap connection between the installation roller 15 and the installation rod 11. After one set of installation rollers 15 is installed, pick up the other set of installation rollers 15 and move it to the left. When the other set of installation rollers 15 moves to the left, the anti-bird rope 13 automatically unfolds and covers the upper part of the breeding pond. When the other set of installation rollers 15 moves to the left end installation rod 11, the anti-bird rope 13 is completely pulled out, and then install the installation roller 15 on the left installation rod 11. At this time, the anti-bird rope 13 is tightened and covers the breeding pond, preventing birds from entering the breeding pond from above;

[0041] The following makes a detailed description of the movement of the sealing plate 17, as Figure 3 and Figure 4As shown in the figure, at this time, the sealing plate 17 slides out of the installation circular roller 15 to close the opening on the upper side of the hanging hook 16, so that the hanging ring 24 cannot slide out of the hanging hook 16. And at this time, due to the action of the spring 28, the limiting rod 31 is inserted into the limiting hole 32, resulting in the rotation rod 23 being unable to rotate. When it is necessary to replace the bird-proof rope 13, pull the screwing block 30 forward to make the limiting rod 31 slide out of the limiting block, and then rotate the screwing block 30. The rotation of the screwing block 30 drives the rotation of the rotating square rod 29, and then drives the rotation of the rotating disc 27 and the rotation rod 23, and further drives the simultaneous rotation of all the driving bevel gears 21. Through the transmission of the driven bevel gears 20, all the threaded rods 19 rotate simultaneously, so that the sealing plate 17 moves to the right along the corresponding threaded rod 19 and is retracted into the installation circular roller 15. The sealing plate 17 no longer closes the opening above the hanging hook 16. After the sealing plate 17 is completely retracted into the installation circular roller 15, release the screwing block 30. Under the action of the restoring force of the spring 28, the screwing block 30 is driven to move backward, so that the limiting rod 31 moves backward again and is inserted into the limiting hole 32. At this time, the hanging ring 24 can be removed from the hanging hook 16 to complete the replacement of the bird-proof rope 13. When it is necessary to close the hanging hook 16 again, operate the screwing block 30 in the same way.

[0042] The escape-proof plastic 5 is used to prevent the river crabs from escaping, and the bird-proof device is used to prevent birds from entering the breeding pond from above. During normal use, the continuous bird repeller 12 starts for a long time to play a continuous bird repelling role. As Figure 6 shown in the figure, the right mounting rod 11 is connected to the infrared alarm transmitter 8, and the left mounting rod 11 is connected to the infrared alarm receiver 33. When a bird is about to enter the breeding pond from the ground, it will pass between the infrared alarm transmitter 8 and the infrared alarm receiver 33. At this time, the infrared rays emitted by the infrared alarm transmitter 8 are blocked, and the infrared alarm receiver 33 cannot receive the infrared rays, so the intermittent bird repeller 7 is activated. The intermittent bird repeller 7 emits a sound to disperse the birds and prevent the birds from entering the breeding pond from the ground. Figure 6 Only the alarm device on one side of the breeding pond is shown. In actual settings, infrared alarm receivers 33 and infrared alarm transmitters 8 can be set on all four sides of the breeding pond; in actual settings, two groups of bird-proof devices can also be set, and the bird-proof ropes 13 of the two groups of bird-proof devices are vertically arranged to improve the bird-proof effect. Subsequently, the mounting frame 22 can also be removed to repair the driving bevel gears 21, etc., to improve the convenience of using the equipment. For the sake of clear view, not all the hatching lines are shown in the attached drawings of the specification, but it does not affect the understanding of the technical solution of this application. This is hereby explained.

[0043] The above are only embodiments of the present invention, and common general technical solutions and / or features in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
