Technical Field
[0001] This utility model relates to the technical field of frozen semen temperature control equipment, specifically a temperature control storage device for frozen semen of breeding rams. Background Technology
[0002] With the development of animal husbandry, artificial insemination technology has been widely used. Frozen semen, as a key material for artificial insemination, is therefore of paramount importance in its storage and management. In the improvement of ram breeds, liquid nitrogen tanks are frequently used to store viable frozen semen. Only with sufficient liquid nitrogen can frozen semen be preserved for a longer period, maintain better sperm motility, and achieve optimal mating results.
[0003] Chinese patent CN202420671942.1 describes a portable frozen semen storage container that improves insulation performance and ensures stable low-temperature storage of frozen semen. Simultaneously, the lightweight shell and handle design enhance portability, meeting the needs of on-site operations or mobile storage. The carrying tube and connecting rod enable convenient storage and retrieval of frozen semen tubes, improving operational efficiency. However, the following drawbacks still exist:
[0004] 1. When a semen sample needs to be removed, a large amount of liquid nitrogen will be lost, causing significant temperature fluctuations inside the storage tank and resulting in waste of liquid nitrogen.
[0005] 2. The storage area of the thumb tube is relatively concentrated, and liquid nitrogen cannot effectively surround the thumb tube, which makes it impossible for the thumb tube to form an effective and stable low temperature field, which is not conducive to maintaining the biological activity of semen. Utility Model Content
[0006] To address the aforementioned technical deficiencies, this solution establishes a storage mechanism to ensure a stable low-temperature field around the semen, allowing each sample of semen to be cooled evenly and maintaining its biological activity; at the same time, it reduces the problem of excessive liquid nitrogen loss caused by the handling of semen.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature storage device for frozen semen of breeding rams, comprising:
[0008] The insulated box has adjustable support legs fixedly installed at its bottom and casters rotatably mounted thereon.
[0009] An insulation cover plate is fixedly and sealed on the top of the insulation box, and multiple mounting holes and slots are provided on the insulation cover plate;
[0010] The mounting slots are used to fix and install the storage mechanism, which is used to isolate the semen of breeding rams in separate areas.
[0011] A compression spring is fixed at one end to the bottom plate of the insulated box and connected to the storage mechanism at the other end.
[0012] Further, preferably, the storage mechanism includes a placement box, which is fixedly installed in the mounting hole groove. A fixing plate is provided on each side of the placement box, and a slide rail is provided on the placement box corresponding to the fixing plate. A slide groove is formed in the fixing plate.
[0013] An adjusting plate is slidably disposed in the slide groove, and multiple slots are provided on the side of the adjusting plate near the slide groove;
[0014] An adjusting rod is slidably disposed within the slide rail, and a locking assembly is provided on the adjusting rod corresponding to the slot; a pressing handle is fixedly provided at one end of the adjusting rod that extends through the slide rail and out of the heat insulation cover plate;
[0015] The base plate is slidably sealed inside the placement box and connected to the compression spring.
[0016] A sealing cap is provided on top of the placement box.
[0017] Furthermore, preferably, the storage mechanism further includes: a slide rail extending through one end of the placement box near the heat-insulating cover;
[0018] An adjustment component is disposed on the placement box and connected to the adjustment plate via the slide rail;
[0019] The drive assembly is mounted on the insulation cover and connected to the adjustment assembly.
[0020] Further, preferably, the locking assembly includes: a locking groove, a locking buckle, and a torsion spring;
[0021] The locking groove is fixedly mounted on the adjusting rod; the latch is rotatably mounted in the locking groove, and the torsion spring is mounted on the connecting shaft between the latch and the locking groove.
[0022] Further, preferably, the adjustment component includes:
[0023] Four pulleys are rotatably mounted diagonally on the placement box. A belt is provided through the four pulleys, and one end of a linkage rod is fixedly mounted on the belt. The other end of the linkage rod is fixedly connected to the adjustment plate through the slide rail.
[0024] Further, preferably, the driving component includes:
[0025] A worm gear is rotatably mounted on the heat insulation cover plate and is coaxially connected to one of the pulleys;
[0026] The worm gear is rotatably mounted on the heat insulation cover plate and meshes with the worm wheel;
[0027] A bevel gear set is installed on the heat insulation cover plate, with a knob at the input end and the output end connected to the worm gear.
[0028] Furthermore, preferably, a sealing strip is provided at all sliding points of the components.
[0029] Compared with the prior art, this utility model provides a constant temperature storage device for frozen semen of breeding rams, which has the following beneficial effects:
[0030] 1. By setting up a storage mechanism, it is ensured that all thumb tubes stored in the insulated box are in the same low-temperature environment, and liquid nitrogen surrounds the thumb tubes to form a stable low-temperature field. This avoids different storage environments for each thumb tube due to temperature differences, ensures that each sample of semen is cooled evenly, maintains its biological activity, and extends its shelf life.
[0031] 2. When a specific thumb tube needs to be removed, adjusting the components and drive mechanism can create a relatively independent sealed space between the placement box and the insulated box, facilitating individual removal without affecting the cryopreservation of other semen. This achieves flexibility and safety in semen retrieval, ensuring convenient operation without affecting the overall storage effect, and improving the reliability and practicality of frozen semen preservation in rams.

[0038] Reference Figures 1-5 This utility model provides a technical solution: a constant temperature storage device for frozen semen of breeding rams, comprising:
[0039] The insulated box 1 has adjustable support legs 2 fixedly installed at its bottom and casters 3 rotatably installed thereon;
[0040] The heat insulation cover plate 5 is fixedly and sealed on the top of the heat insulation box 1, and multiple mounting holes and slots are provided on the heat insulation cover plate 5;
[0041] The mounting slot is used to fix and install the storage mechanism 4, and the storage mechanism 4 is used to isolate the semen of breeding rams in separate areas.
[0042] The compression spring 6 has one end fixedly mounted on the bottom plate of the insulated box 1, and the other end connected to the storage mechanism 4.
[0043] After processing, the qualified ram semen is placed in a thumb tube, which is then inserted into the storage mechanism 4. During the sealing process of the thumb tube in the storage mechanism 4, the compression spring is compressed and deformed, thereby ensuring the fixing effect of the storage mechanism 4 on the thumb tube storing the semen, and thus effectively avoiding damage to the semen caused by external vibrations.
[0044] It should be noted that multiple storage mechanisms 4 are placed inside the insulated box 1 via an insulated cover 5. After all the ram semen has been placed inside, all storage mechanisms 4 are sealed. After sealing, liquid nitrogen is poured into the insulated box 1, rapidly cooling it to -196°C to create an ultra-low temperature environment, ensuring the long-term preservation of the ram semen without loss of activity. At this time, the storage mechanisms 4 are in an open state inside the insulated box 1, causing liquid nitrogen to circulate around their thumb tubes, forming a stable low-temperature field that effectively isolates them from external temperature fluctuations, thus ensuring semen quality.
[0045] Meanwhile, it ensures that all thumb tubes stored in the insulated box are in the same low-temperature environment, avoiding different storage environments due to temperature differences. This ensures that each sample of semen is cooled evenly, maintaining its biological activity and extending its shelf life. Furthermore, the device is compact in design, easy to operate, and suitable for large-scale semen storage needs.
[0046] When a specific sample of semen needs to be retrieved, the corresponding storage mechanism 4 can be adjusted to isolate it from the internal environment of the insulated box 1, creating an independent space. This allows for individual retrieval without affecting the cryopreservation of other semen samples. This achieves flexibility and safety in semen retrieval, ensuring convenient operation without compromising overall storage effectiveness, and enhancing the reliability and practicality of frozen ram semen preservation.
[0047] In a preferred embodiment, the storage mechanism 4 includes a placement box 41, which is fixedly installed in the mounting hole groove. A fixing plate is provided on each side of the placement box 41, and a slide rail 44 is also provided on the placement box 41 corresponding to the fixing plate. A slide groove is provided in the fixing plate.
[0048] An adjusting plate 42 is slidably disposed in the slide groove, and a plurality of slots 43 are provided on the side of the adjusting plate 42 near the slide rail 44;
[0049] An adjusting rod 45 is slidably disposed within the slide rail 44, and a locking assembly 46 is provided on the adjusting rod 45 corresponding to the slot 43; a pressing handle 48 is fixedly disposed at one end of the adjusting rod 45 that extends through the slide rail 44 and out of the heat insulation cover plate 5.
[0050] The base plate 47 is slidably sealed inside the placement box 41 and connected to the compression spring 6; there is damping between the base plate 47 and the placement box 41 to prevent the base plate 47 from popping out too quickly under the action of the compression spring 6 and to ensure a smooth transition.
[0051] A sealing cap 49 is disposed on top of the placement box 41.
[0052] In a preferred embodiment, the storage mechanism 4 further includes a slide rail extending through one end of the placement box 41 near the heat insulation cover 5;
[0053] Adjustment component 8 is disposed on the placement box 41 and connected to the adjustment plate 42 via the slide rail;
[0054] The drive component 7 is installed on the insulation cover plate 5 and connected to the adjustment component 8.
[0055] It should be explained that the sealing cap 49 is tightly connected to the placement box 41 by threads to ensure a tight seal. When placing the thumb tube, the thumb tube is inserted into the placement box 41. During insertion, the bottom of the thumb tube contacts the base plate 47, and the compression spring 6 provides support force to ensure that the thumb tube is firmly fixed after the sealing cap 49 is tightened, preventing it from shaking.
[0056] After the sealing cap 49 is tightened, the adjustment component 8 is controlled by the drive component 7 to drive the adjustment plate 42 to slide, ensuring that the adjustment plate 42 is in the open state, so that the internal space of the placement box 41 and the incubator 1 are integrated, ensuring that all thumb tubes in the incubator 1 are in the same environment, and avoiding the impact of local temperature fluctuations on the quality of semen preservation.
[0057] When a sample of semen needs to be retrieved, the drive component 7 operates in reverse, the adjustment plate 42 slides to the closed position, and the slot 43 precisely engages with the locking component 46 to form an independent space. This reduces external interference to the interior of the insulated box 1 during the retrieval of that sample of semen, prevents excessive liquid nitrogen loss from affecting the preservation of other semen, effectively saves liquid nitrogen usage, reduces storage costs, ensures high efficiency and precision in each operation, further optimizes the overall performance of frozen semen preservation in rams, and improves the stability and reliability of experimental operations.
[0058] After examining and extracting the semen sample, press the handle 48 to release the engagement between the slot and the locking assembly 46. After release, control the adjustment assembly 8 again via the drive assembly 7 to restore the adjustment plate 42 to the open state, ensuring that the placement box 41 and the internal space of the insulated box 1 are reconnected. Quickly freeze the extracted semen sample to prevent the temperature rise from causing secondary impact on the semen quality, while maintaining a constant temperature in the overall environment, reducing the loss of liquid nitrogen, and ensuring the long-term stable preservation of the remaining semen.
[0059] This design not only enhances operational flexibility but also further strengthens the safety of semen preservation, ensuring that each sample of semen is preserved in optimal condition to meet the high standards required for scientific research and production.
[0060] In a preferred embodiment, the latch assembly 46 includes: a latch groove 461, a latch 462, and a torsion spring;
[0061] The locking groove 461 is fixedly mounted on the pressing handle 48; the latch 462 is rotatably mounted in the locking groove 461, and the torsion spring is mounted on the connecting shaft between the latch 462 and the locking groove 461.
[0062] During the process of sealing the placement box 41 with the adjustment plate 42, the slot 43 squeezes the latch 462 to make it rotate until the latch 462 and the slot 461 are fully engaged, forming a stable seal, thereby preventing the liquid nitrogen in the insulation box 1 from flowing out and causing large temperature fluctuations.
[0063] When the handle 48 is pressed, the adjusting rod 45 slides downward in the slide rail 44, thereby causing the latch 462 to slide down and break free from the engagement with the slot 43, thus unlocking the device.
[0064] After unlocking, the adjustment plate 42 is smoothly reset under the action of the drive component 7, ensuring seamless connection between the placement box 41 and the insulated box 1, quickly restoring the constant temperature environment, effectively preventing the formation of temperature gradients, ensuring that the remaining semen is preserved in a stable low temperature, further extending its activity, and improving the reliability and practicality of the overall preservation system.
[0065] In a preferred embodiment, the adjustment component 8 includes:
[0066] Four pulleys 81 are rotatably mounted on opposite sides of the placement box 41. A belt 82 is provided through the four pulleys 81. One end of a linkage rod 83 is fixedly provided on the belt 82. The other end of the linkage rod 83 is fixedly connected to the adjustment plate 42 through the slide rail.
[0067] The drive assembly 7 drives the belt 82 to move by rotating the drive pulley 81, which in turn pushes the linkage rod 83 to slide along the slide rail, precisely controlling the opening and closing of the adjustment plate 42, ensuring smooth operation without temperature difference interference, and further improving the stability of the semen preservation environment and the convenience of operation.
[0068] In a preferred embodiment, the driving component 7 includes:
[0069] The worm gear 71 is rotatably mounted on the heat insulation cover plate 5 and is coaxially connected to one of the pulleys 81.
[0070] The worm gear 72 is rotatably mounted on the heat insulation cover plate 5 and meshes with the worm wheel 71;
[0071] A bevel gear set is installed on the heat insulation cover plate 5, with a knob 73 at the input end and the output end connected to the worm gear 72.
[0072] It should be explained that by rotating the bevel gear set by the knob 73, the worm gear 72 is driven to rotate, which in turn drives the worm wheel 71 and the pulley 81 to rotate synchronously, precisely controlling the movement of the linkage rod 83, ensuring that the adjusting plate 42 opens and closes smoothly, avoiding temperature fluctuations, and ensuring a constant environment for semen preservation.
[0073] In a preferred embodiment, a sealing strip is provided at each sliding part of the component. The sealing strip is provided to ensure the sealing structure of the storage mechanism 4 when a thumb tube is removed, preventing the loss of liquid nitrogen and causing a large temperature difference change in the incubator 1. This ensures that the remaining semen in the incubator 1 is not affected by the external temperature, maintains the overall low temperature environment, and improves the preservation efficiency.
[0074] In practice, the prepared ram semen thumb tube is placed into the placement box 41, and the sealing cover 49 is closed, ensuring that the sealing cover 49 is tightly sealed to the placement box 41. As the knob 73 is gently rotated, the worm gear 71 drives the pulley 81 to rotate slowly, the linkage rod 83 slides smoothly along the slide rail, and the adjusting plate 42 slides to make the thumb tube integrate into the environment inside the insulated box 1 to quickly freeze the semen. The whole process is seamless and without any temperature difference disturbance.
[0075] When it is necessary to remove the thumb tube of a single ram semen, the knob 73 is operated in reverse, the linkage rod 83 is precisely returned to its original position, and the adjustment plate 42 and the placement box 41 form an independent space relative to the insulated box 1, ensuring that the remaining semen is not affected and maintaining a stable low temperature.
[0076] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
