[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0027] Please combine Figures 1 to 5 A simple duck frozen semen production device includes an insulated box 1, and the top of the insulated box 1 is provided with a box cover 2. The insulated box 1 and the box cover 2 of this embodiment are both made of insulating materials. Specifically, the insulated box 1 and the box cover 2 can be made of 2-3 cm foam material. A scale 9 parallel to its height direction is provided on the side wall inside the insulated box 1. The size of the scale 9 is 50-60 cm long, 40-50 cm wide, and 30-40 cm high.

[0028] A storage box 3 is placed in the incubator 1, and a mesh bed is arranged above the storage box 3. Specifically, the mesh bed includes a frame 4, the bottom of the frame 4 is supported on the top edge of the storage box 3, and a mesh surface 5 that can carry a syringe 6 is arranged between the top of the frame 4.

[0029] In this embodiment, the length and width of the storage box 3 are 6-8 cm, the height is consistent with the height of the net bed, the bottom surface is a copper plate, and the thickness of the copper plate is 0.1 cm.

[0030] The net bed can be made of copper material, the length of the net bed is 1 / 2 to 2 / 3 of the length of the inner wall of the incubator 1, the width is 1-2 cm smaller than the inner wall of the incubator 1, and the height is 1 / 2 to 2 / 3 of the height of the incubator 1. The frame 4 of the net bed is made of 0.2-0.3 cm copper wire, and the mesh surface 5 can be made of 0.3-0.5 mm copper wire.

[0031] A syringe 6 can be placed on the net bed, and a straw 7 connected thereto is coaxially arranged at the injection port of the syringe 6 , and a pipe plug 8 is detachably arranged at one end of the straw 7 away from the syringe 6 .

[0032] Specifically, the specification of the syringe 6 can be 2-5 ml, and the specification of the straw 7 can be 250 microliters. The straw 7 and the syringe 6 are bonded by gluing. The straw 7 and the plug 8 are threadedly connected to facilitate the disassembly of the plug 8 and the straw 7.

[0033] In summary, the present embodiment provides a method for preparing frozen duck semen, comprising the following steps:

[0034] S1. After semen is collected, it is mixed with isothermal semen diluent at a ratio of 1:1 and equilibrated at 4 degrees Celsius for 1 hour. After equilibration, it is mixed with semen diluent containing cryoprotectant at a ratio of 1:1 and equilibrated at 4 degrees Celsius for 30 minutes (DMA can be used as the protective agent, with a final concentration of 6-8%).

[0035] S2. Pour liquid nitrogen into the insulated box 1 until the liquid nitrogen is 3 cm below the upper layer of the mesh bed, cover the box with a lid, and pre-cool for 10-15 minutes.

[0036] S3, use the straw 7 of the syringe 3 to suck the semen into the straw and seal it with the pipe plug 8, put it flat on the net bed and fumigate it with liquid nitrogen for 7 minutes (cover the box cover 2 during the fumigation process), put it in the empty space next to the net bed in the incubator 1 after the fumigation, and freeze it with liquid nitrogen for 3-5 minutes.

[0037] S4. Then place the cloth bag used to collect frozen semen in the storage box, pick up the frozen semen with tweezers and put it into the cloth bag, tie the shrink opening of the cloth bag tightly, and label it, and transfer it to a liquid nitrogen tank for long-term storage.

[0038] In order to improve the supporting stability of the net bed on the storage box 3, in this embodiment, the bottom of the frame 4 of the net bed and the top edge of the storage box 3 can be welded together so that the net bed and the storage box 3 form a whole.

[0039] It is worth mentioning that in order to improve the supporting stability of the net bed on the storage box 3 and to facilitate the disassembly and assembly of the net bed on the storage box 3, the storage box 3 of this embodiment is provided with a first slot 10 for the bottom of the frame 4 to be inserted, and a docking block 11 is provided in the first slot 10. The top of the docking block 11 is provided with a docking groove 12 which is snap-fitted with the bottom of the frame 4.

[0040] It can be seen that, through the snap-fitting cooperation between the bottom of the frame 4 and the docking groove 12 of the docking block 11, it can be preliminarily achieved that the supporting stability of the net bed on the storage box 3 can be improved, and the net bed can be easily disassembled and assembled on the storage box 3.

[0041] Furthermore, a pressure rod 14 is provided at the bottom of the docking block 11 , and a cylinder 15 is rotatably provided at the bottom of the first slot 10 , and the cylinder 15 is rotatably connected to the inner wall of the slot of the first slot 10 through a bearing.

[0042] The cylinder 15 is provided with a second slot 16, the bottom of the pressure rod 14 is slidably inserted into the second slot 16, and the second slot 16 is provided with a spiral limiting slot 17 (such as Figure 4 ), a limit block 18 is provided on the pressure rod 14 and is slidably engaged with the limit groove 17, and a clamping hole 19 is provided on the outer wall of the cylinder 15. The maximum rotation angle of the cylinder 15 is 180 degrees each time.

[0043] A card rod 20 that cooperates with the card hole 19 is elastically inserted on the outer wall of the storage box 3. Specifically, a slide groove 21 is provided in the box wall of the storage box 3, and a slider 22 is slidably connected in the slide groove 21. The card rod 20 passes through and is fixed on the slider 22. A second spring is sleeved on the outer side of the card rod 20, and the two ends of the second spring are respectively connected to the outer wall of the slider 22 and the wall of the slide groove 21.

[0044] A fixing plate 13 is provided in the first slot 10, and the fixing plate 13 is located between the docking block 11 and the cylinder 15. A pressure rod 14 slides through the fixing plate 13, and a first spring is sleeved on the outer side of the pressure rod 14. Both ends of the first spring are respectively connected to the top of the fixing plate 13 and the bottom of the docking block 11.

[0045] Two gears 23 are arranged opposite to each other on the docking block 11, and racks 26 that can mesh with the two gears 23 are arranged axially on the groove walls on both sides of the first slot 10, and two curved swing arms 24 are coaxially fixed on the two gears 23. A clamping plate 25 is provided at one end of the two swing arms 24, and a clamping space for clamping and fixing the frame 4 is formed between the two clamping plates 25.

[0046] In summary, when the bottom of the frame 4 is stuck in the docking groove 12, as the bottom of the frame 4 continues to move downward, it can drive the docking block 11 and the pressure rod 14 to move downward, and the downward movement of the docking block 11 will cause the gear 23 to contact and engage with the rack 26 on the groove wall of the first slot 10 and rotate, so that the two clamps 25 are gathered together through the swing arm 24, thereby completing the clamping and fixing of the outer wall of the bottom of the frame 4, thereby increasing the connection stability.

[0047] The docking block 11 drives the pressure rod 14 to move downward (the first spring is compressed and deformed), and the pressure rod 14 will slide and rub through the limit block 18 to squeeze the spiral limit groove 17, so as to force the cylinder 15 to rotate in one direction, so that the clamping hole 19 on the cylinder 15 rotates to the position of the clamping rod 20. The clamping rod 20 will be clamped into the clamping hole 19 under the elastic force of the second spring thereon to lock and fix the position of the cylinder 15 after rotation, which can not only maintain a sufficient insertion depth of the bottom of the frame 4 in the first slot 10, but also maintain the clamping state of the clamping plate 25 on the outer wall of the bottom of the frame 4.

[0048] When the net bed on the storage box 3 needs to be removed, it is only necessary to pull the latch rod 20 to disengage it from the latch hole 19 of the cylinder 15. Then, under the release of the elastic force of the first spring, the docking block 11 will be pushed back to the initial position. During this period, the clamping plate 25 will release the clamping effect on the bottom outer wall of the frame 4, which is convenient and efficient.

[0049] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
