Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a transfer cabinet for bovine embryo transfer. Background Technology

[0002] Bovine embryo transfer is an important biotechnology that aims to accelerate the breeding of superior breeds and the protection of endangered species by transferring embryos from high-quality cows into recipient cows. Bovine embryo transfer requires the use of cryopreservation equipment for the low-temperature storage and transportation of embryos.

[0003] Patent document CN216409418U discloses a cryogenic device for bovine embryo transfer that can monitor temperature. The device includes a cryogenic chamber with a cabinet door fixedly connected to the left side of the front of the chamber. The cryogenic chamber is equipped with a temperature processing system, which solves the problem that cryogenic devices for bovine embryo transfer cannot display the temperature. This cryogenic device for bovine embryo transfer that can monitor temperature has the advantage of displaying the temperature. When the temperature inside the cryogenic device is too high, the operator can detect it in time, thereby protecting the bovine embryo.

[0004] In actual use, the cryopreservation device for bovine embryo transfer proposed in the above patent documents lacks a structure to limit the embryo tubes inside the device. When a large number of embryo tubes are placed together, cold air cannot circulate between the tubes, making it difficult for some tubes far from the cold source to be cooled sufficiently, thus affecting the storage effect of the embryos. Utility Model Content

[0005] This utility model discloses a transfer cabinet for bovine embryo transfer. To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A transfer cabinet for bovine embryo transfer includes a transfer cabinet body, wherein the interior of the transfer cabinet body is provided with a test tube limiting mechanism and a cooling mechanism;

[0007] The test tube limiting mechanism includes three test tube limiting seats arranged side by side inside the transfer cabinet, and all three test tube limiting seats are rotatably mounted on the inner bottom wall of the transfer cabinet. The upper surface of the test tube limiting seat is provided with several cylindrical slots, the outer surface of the test tube limiting seat is provided with several first strip-shaped vent holes, the interior of the test tube limiting seat is provided with a flow guiding cavity, and the inner wall of the cylindrical slot is provided with a second strip-shaped vent hole.

[0008] A base shell is fixedly installed on the lower surface of the transfer cabinet. The cooling mechanism includes a refrigeration box fixedly connected to the bottom wall of the base shell. A refrigerator is fixedly installed inside the refrigeration box. A cold air delivery pipe is rotatably installed between the refrigeration box and the test tube limiting seat.

[0009] By setting it up.

[0010] In a preferred embodiment, a linkage gear ring is fixedly provided at the bottom of the test tube limiting seat, and the three linkage gear rings mesh sequentially from left to right. A drive motor is fixedly provided inside the base shell, and the output shaft of the drive motor extends into the interior of the transfer cabinet and is fixedly provided with a drive gear, which meshes with the linkage gear ring.

[0011] In a preferred embodiment, the top end of the cold air delivery pipe is fixedly connected to the bottom end of the test tube limiting seat, and the top air outlet of the cold air delivery pipe extends into the interior of the guide cavity.

[0012] In a preferred embodiment, the positions of the first and second strip-shaped vents correspond to the cylindrical slots, and the second strip-shaped vent connects the cylindrical slots to the flow guiding cavity.

[0013] In a preferred embodiment, the front and rear inner walls of the transfer cabinet are fixedly provided with circulating air intake shells, the surface of which is provided with a plurality of circulating air intake holes, and the inner bottom wall of the transfer cabinet is embedded with a circulating ventilation pipe, which is located between the circulating air intake shell and the refrigeration box.

[0014] In a preferred embodiment, the bottom end of the circulating ventilation duct extends into the interior of the refrigeration box, and the top end of the circulating ventilation duct extends into the interior of the circulating air intake shell. A circulating fan is fixedly installed on the inner wall of the circulating ventilation duct, and the air intake end of the circulating fan corresponds to the position of the circulating air intake shell.

[0015] In a preferred embodiment, the cold air delivery pipe is rotatably connected to the inner bottom wall of the transfer cabinet via a bearing, and a limit ring is fixedly provided at the top of the test tube limiting seat.

[0016] As can be seen from the above, the bovine embryo transfer transfer cabinet provided by this utility model has the following technical effects.

[0017] Firstly, by setting up a test tube limiting mechanism inside the transfer cabinet, the embryo test tubes can be limited by the cylindrical slots on the surface of the test tube limiting seat. The test tubes can be ventilated by the first and second vent holes on the surface of the test tube limiting seat and inside the cylindrical slots. The cold air generated by the cooling box is then transported to the cylindrical slots through the air guiding cavity of the test tube limiting seat. The cold air is used to cool the test tubes, achieving the effect of low-temperature storage. It can also keep the surface of the test tubes at a uniform low temperature, which is beneficial for the transfer and transportation of embryos.

[0018] Secondly, by setting a linkage gear ring on the surface of the test tube limiting seat, the drive motor can drive the drive gear and linkage gear ring to rotate, thereby causing the test tube limiting seat to rotate at a constant speed in the transfer cabinet. This allows the cold air to fully surround the test tubes and ensures that test tubes at different positions are in uniform contact with the cold air in the transfer cabinet, thus improving the cooling effect on the embryo test tubes.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1 and Figure 2 A transfer cabinet for bovine embryo transfer includes a transfer cabinet body 1. The transfer cabinet body 1 is equipped with a test tube limiting mechanism 2 and a cooling mechanism 3. It should be noted that the test tube limiting mechanism 2 can limit and fix the test tube containing bovine embryos, and the cooling mechanism 3 is used to cool and lower the temperature of the test tube.

[0028] Reference Figure 3 and Figure 4In a preferred embodiment, the test tube limiting mechanism 2 includes three test tube limiting seats 201 arranged in parallel inside the transfer cabinet 1, and the three test tube limiting seats 201 are rotatably disposed on the inner bottom wall of the transfer cabinet 1. The upper surface of the test tube limiting seat 201 is provided with a plurality of cylindrical slots 202, which can limit the test tubes, and the inner diameter of the cylindrical slots 202 is slightly larger than the diameter of the test tube, so that a certain ventilation gap is left between the test tube and the inner wall of the cylindrical slots 202.

[0029] Reference Figure 3 A limit ring 208 is fixedly provided at the top of the test tube limiting seat 201, and the top of the test tube can be limited by setting the limit ring 208.

[0030] It should be noted that the front and rear inner walls of the transfer cabinet 1 are fixedly equipped with circulating air intake shells 7. The surface of the circulating air intake shells 7 is provided with several circulating air intake holes 8. The inner bottom wall of the transfer cabinet 1 is embedded with a circulating ventilation pipe 9, which is located between the circulating air intake shells 7 and the refrigeration box 301.

[0031] Specifically, the circulating ventilation pipe 9 can connect the cooling box 301 and the circulating air intake shell 7, and input the circulating air in the circulating air intake shell 7 into the cooling box 301, and use the cooler 302 to cool and lower the circulating air.

[0032] It should be further explained that the bottom end of the circulating ventilation pipe 9 extends into the interior of the cooling box 301, and the top end of the circulating ventilation pipe 9 extends into the interior of the circulating air intake shell 7. A circulating fan 5 is fixedly installed on the inner wall of the circulating ventilation pipe 9, and the air intake end of the circulating fan 5 corresponds to the position of the circulating air intake shell 7.

[0033] Specifically, the circulating fan 5 can be used to input the cooling air in the cooling box 301 into the cold air delivery pipe 303, and then the cold air is input into the guide cavity 204 in the test tube limit seat 201 through the cold air delivery pipe 303.

[0034] It should be noted that a control panel is provided on the surface of the base shell 4, and a temperature sensor is provided inside the transfer cabinet 1. The control panel is electrically connected to the temperature sensor, the cooler 302, the drive motor 6 and the circulating fan 5 respectively. The temperature sensor can be used to monitor the internal temperature of the transfer cabinet 1, so as to facilitate the staff to adjust and control the working temperature of the cooler 302.

[0035] Reference Figure 2 The outer surface of the test tube limiting seat 201 is provided with several first strip-shaped vent holes 203, the interior of the test tube limiting seat 201 is provided with a flow guiding cavity 204, and the inner wall of the cylindrical slot 202 is provided with a second strip-shaped vent hole 205.

[0036] It should be noted that the positions of the first strip-shaped vent 203 and the second strip-shaped vent 205 are both corresponding to the cylindrical slot 202, and the second strip-shaped vent 205 connects the cylindrical slot 202 and the flow guiding cavity 204.

[0037] Specifically, the cooling air in the guide cavity 204 is introduced into the cylindrical slot 202 through the second strip-shaped vent 205, thereby cooling the test tube with cold air. Then, the air is introduced into the outside of the test tube limiting seat 201 through the first strip-shaped vent 203, so as to achieve the effect of circulating cooling of the test tube.

[0038] It should be noted that the top end of the cold air delivery pipe 303 is fixedly connected to the bottom end of the test tube limiting seat 201, and the air outlet at the top end of the cold air delivery pipe 303 extends into the interior of the guide cavity 204.

[0039] It is worth noting that by setting up a test tube limiting mechanism 2 inside the transfer cabinet, the embryo test tubes can be limited by the cylindrical slots 202 on the surface of the test tube limiting seat 201. The test tubes can be ventilated by the first strip-shaped vent holes 203 and the second strip-shaped vent holes 205 on the surface of the test tube limiting seat 201 and inside the cylindrical slots 202. The cold air generated by the cooling box 301 is transported to the cylindrical slots 202 through the flow guiding cavity 204 of the test tube limiting seat 201. The cold air is used to cool the test tubes, achieving the effect of low-temperature storage. It can also keep the surface of the test tubes at a uniform low temperature, which is beneficial for the transfer and transportation of embryos.

[0040] It should be further explained that a linkage gear ring 206 is fixedly installed at the bottom of the test tube limiting seat 201. The three linkage gear rings 206 mesh sequentially from left to right. A drive motor 6 is fixedly installed inside the base shell 4. The output shaft of the drive motor 6 extends into the interior of the transfer cabinet 1 and is fixedly installed with a drive gear 207. The drive gear 207 meshes with the linkage gear rings 206.

[0041] It is worth noting that by setting a linkage gear ring 206 on the surface of the test tube limiting seat 201, the drive motor 6 can drive the drive gear 207 and the linkage gear ring 206 to rotate, thereby simultaneously driving the three test tube limiting seats 201 to rotate at a uniform speed in the transfer cabinet. This allows the cold air to fully surround the test tubes and ensures that the test tubes at different positions are in uniform contact with the cold air in the transfer cabinet, thus improving the cooling effect on the embryo test tubes.

[0042] Reference Figure 2 and Figure 3In a preferred embodiment, a base shell 4 is fixedly provided on the lower surface of the transfer cabinet 1, and the cooling mechanism 3 includes a refrigeration box 301 fixedly connected to the bottom wall of the base shell 4. A cooler 302 is fixedly provided inside the refrigeration box 301, and a cold air delivery pipe 303 is rotatably provided between the refrigeration box 301 and the test tube limiting seat 201.

[0043] It should be noted that the cooler 302 is a semiconductor cooler commonly used in the prior art. A semiconductor cooler is a device that uses the thermoelectric effect of semiconductors to generate cooling capacity. It is also called a thermoelectric cooler. Semiconductor coolers have the characteristics of being noiseless, vibration-free, requiring no refrigerant, small in size, and light in weight. They are also reliable in operation, easy to operate, and easy to adjust the cooling capacity. Semiconductor coolers have a relatively small coefficient of performance and are mainly used in applications with low cooling capacity and small footprint.

[0044] The cooling end of the cooler 302 is located inside the cooler box 301, and its heating end extends to the outside of the base shell 4. The heating end of the cooler 302 is equipped with a cooling fan, which can dissipate heat from the heating end of the cooler 302.

[0045] The cold air delivery pipe 303 is rotatably connected to the inner bottom wall of the transfer cabinet 1 through a bearing. When the drive motor 6 drives the test tube limit seat 201 to rotate in the transfer cabinet 1, it can simultaneously drive the cold air delivery pipe 303 to rotate between the refrigeration box 301 and the transfer cabinet 1, while maintaining air circulation inside the cold air delivery pipe 303.

[0046] Working principle: In use, first, place the test tube containing the bovine embryo into the cylindrical slot 202 on the surface of the test tube limiting seat 201, then close the lid of the transfer cabinet 1, and start the cooler 302, drive motor 6 and circulating fan 5 through the control panel. The cooler 302 can be used to cool the air in the cooling box 301. Then, the circulating fan 5 uses the cooling air in the cooling box 301 to be input into the guide cavity 204 of the test tube limiting seat 201 through the cold air delivery pipe 303. Then, the cold air is input into the cylindrical slot 202 through the second strip-shaped vent 205 to cool the test tube. Then, the cold air is delivered to the outside of the cylindrical slot 202 through the first strip-shaped vent 203 and distributed to the transfer cabinet 1. Then, the air in the transfer cabinet 1 is re-drawn into the cooling box 301 through the circulating air intake hole 8 on the surface of the circulating air intake shell 7, realizing the circulating cooling inside the transfer cabinet.

[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
