Specifically, the top of this insulation can 1 sets up the case mouth, through this case mouth, the user can pour into above-mentioned insulation can 1 with liquid water 2 or kind pig semen dilution solution into, and the bottom of the case intercommunication of insulation can 1 is provided with drain pipe 3, and drain pipe 3 is provided with the valve 4 that is used for controlling the break-make, when the liquid in the need discharge insulation can 1, then opens above-mentioned valve 4, and the liquid in the insulation can 1 is discharged through above-mentioned drain pipe 3. Of course, the box cover 105 is mounted at the box opening of the incubator 1, and the box cover 105 seals the box opening of the incubator 1 to ensure that the liquid therein cannot leak out from the box opening.
The water temperature control system 5 is installed in the incubator 1, and the water temperature control system 5 is used for controlling the temperature of the liquid water 2 in the incubator 1, so that the water temperature of the liquid water 2 in the incubator 1 is more suitable for storing the boar semen (specifically, the water temperature control system 5 controls the liquid water 2 in the incubator 1 to be 15-25 ℃). It is easy to understand that the above-mentioned water temperature control system 5 can not only raise the temperature of the liquid water 2 in the heat preservation box 1, but also lower the temperature of the liquid water 2 in the heat preservation box 1. When the external temperature is high (for example, summer), the water temperature control system 5 cools the water temperature in the heat insulation box 1; when the outside temperature is low (for example, winter), the water temperature control system 5 heats the water temperature in the incubator 1. It should be noted that the above-mentioned temperature rise and temperature drop are temperature changes, i.e. temperature changes.

In addition, during long-distance transportation, the semen storage part 6 suspended in the liquid water 2 is not fixed at a certain position in the heat insulation box 1, and is in a free state in the heat insulation box 1, namely, the semen storage part 6 moves in the heat insulation box 1, and during the movement process, the semen storage part 6 is shaken, so that the semen temperature of the boars in each area in the semen storage part 6 is more uniform. In other words, the liquid water 2 in the temperature control box can ensure that the temperature change and the uniformity of each area of the semen storage part 6 are ensured, so that the temperature of the boar semen in each area of the semen storage part 6 is more uniform. Furthermore, the liquid water 2 has buffering effect, so the liquid water 2 in the heat preservation box 1 can absorb vibration energy in the conveying process, so that the semen storage part 6 is stored in the heat preservation box 1 more safely, the specific heat capacity of water is larger than that of air, and the heat preservation effect of the transport box provided by the embodiment is better. Therefore, the water bath type boar semen heat-preserving transport box provided by the embodiment is used for transporting the boar semen, so that the death rate of sperms in the boar semen can be reduced, and the quality of the boar semen transported to a destination is ensured to be higher.
When the pig semen storage device is specifically used, the pig semen is firstly filled into the semen storage part 6, then a user injects air into the inflatable floating ball 7 to expand the inflatable floating ball 7, then the semen storage part 6 and the inflatable floating ball 7 are put into the liquid water 2 in the heat preservation box 1 together, the inflatable floating ball 7 floats or floats in the liquid water 2, the semen storage part 6 floats in the liquid water 2, and finally the box cover 105 of the heat preservation box 1 is covered. And then the whole heat-preservation conveying box is moved to a conveying vehicle.

The plurality of semen storage parts 6 can store more boar semen. The plurality of semen storage parts 6 are suspended in the liquid water 2 in the heat insulation box 1, and the liquid water 2 has a buffering function, so that the semen storage parts 6 are not damaged even if collision occurs between the semen storage parts 6 during floating.
The water temperature control system 5 includes a water pump 502, a first thermally insulated chamber 504, a second thermally insulated chamber 508, a controller 512, and a plurality of temperature sensors 501, wherein:
the plurality of temperature sensors 501 are all installed on the inner wall of the incubator 1, and the plurality of temperature sensors 501 are respectively located at different depths of the liquid water 2 to detect the water temperatures of the liquid water 2 at the different depths. The plurality of temperature sensors 501 are electrically connected to the controller 512, so that the water temperature sensed by the temperature sensors 501 is processed by the controller 512. Alternatively, the temperature sensor 501 in the present embodiment may be a PLC, a chip, or a circuit board. An installation case is provided on the outer wall of the incubator 1, and the controller 512 is installed in the installation case.
The water pump 502 is installed in the incubator 1, so as to be used for extracting liquid water 2 (or boar semen dilution solution) in the incubator 1, and a three-way electromagnetic valve 503 is arranged at the water outlet end of the water pump 502 in a communicating manner. The water pump 502 and the three-way electromagnetic valve 503 are electrically connected to the controller 512, and the controller 512 is used to control the operation states of the water pump 502 and the three-way electromagnetic valve 503. Of course, a power supply is also included and is electrically connected to the controller 512 to supply power to the water pump 502. Specifically, when a temperature sensor 501 detects a temperature anomaly, the controller 512 drives the water pump 502 and the three-way electromagnetic valve 503 to operate.
The first heat insulating chamber 504 is an aluminum alloy chamber with aluminum foil paper or tin foil paper adhered to the chamber wall, and has a good heat insulating effect. A first water pipe 505 is provided in the first heat-insulating chamber 504, and one end of the first water pipe 505 is connected to one outlet of the three-way electromagnetic valve 503, and a first water outlet pipe 506 extending out of the first heat-insulating chamber 504 is connected to the other end of the first water pipe 505. A cooling body 507 for cooling the first water pipe 505 is provided in the first heat insulating chamber 504. Optionally, the refrigerating unit 507 in this embodiment is ice, and the first water pipe 505 is disposed in a serpentine shape in the first heat insulation chamber 504. When the temperature sensor 501 detects that the water temperature in the incubator 1 is higher than the preset temperature, the controller 512 controls the water pump 502 to operate, and drives the three-way electromagnetic valve 503 to guide water into the first water pipe 505, and the water is cooled by the first water pipe 505 and then discharged out of the first heat insulation chamber 504 (i.e. discharged into the incubator 1) through the first water outlet pipe 506, so that cold energy is injected into the incubator 1 to cool the liquid water 2 in the incubator 1. When the temperature of the liquid water 2 in the incubator 1 falls to a suitable range, the controller 512 turns off the water pump 502. Preferably, a first one-way valve 514 is installed in the first water outlet pipe 506, and the first one-way valve 514 allows water to be discharged from the first water outlet pipe 506 to the incubator 1, but water in the incubator 1 cannot flow back into the first water outlet pipe 506. When the first water outlet pipe 506 discharges cold water, the cold water is actually flushed into the liquid water 2 in the heat insulation box 1, and the flushed cold water can increase the disturbance of the water in the heat insulation box 1, so that the water temperature of each area in the heat insulation box 1 is more area-balanced. Of course, the refrigerating body 507 in the present embodiment may be a phase change material.
The second heat-insulating chamber 508 is an aluminum alloy chamber with aluminum foil paper or tin foil paper adhered to the chamber wall, and has a good heat-insulating effect. A second heat-insulating chamber 508 is installed on the inner bottom wall of the heat-insulating box 1 and is located near the middle of the heat-insulating box 1, a second water pipe 509 is provided in the second heat-insulating chamber 508, one end of the second water pipe 509 is communicated with the other outlet of the three-way electromagnetic valve 503, and a second water outlet pipe 510 extending out of the second heat-insulating chamber 508 is connected to the other end of the second water pipe 509.

Optionally, the heating body 511 in this embodiment is a heating wire, and the heating wire is wound around the second water pipe 509. When the temperature sensor 501 detects that the water temperature in the incubator 1 is lower than the preset temperature, the controller 512 controls the water pump 502 to operate and drives the three-way electromagnetic valve 503 to guide water into the second water pipe 509, and the controller 512 controls the power supply to supply power to the heating wire to heat the second water pipe 509. After the water is heated by the second water pipe 509, the water is discharged to the outside of the second heat insulation chamber 508 (i.e., discharged into the heat insulation box 1) through the second water outlet pipe 510, so that heat is injected into the heat insulation box 1 to heat the liquid water 2 in the heat insulation box 1. When the temperature of the liquid water 2 in the incubator 1 rises to a suitable range, the controller 512 turns off the water pump 502 described above. Preferably, a first one-way valve 514 is also installed in the second water outlet pipe 510, and the first one-way valve 514 allows water to be discharged from the second water outlet pipe 510 into the incubator 1, while water in the incubator 1 cannot flow back into the second water outlet pipe 510. When the second water outlet pipe 510 discharges hot water, the hot water is actually flushed into the liquid water 2 in the heat insulation box 1, and the flushed hot water can increase the disturbance of the water in the heat insulation box 1, so that the water temperature of each area in the heat insulation box 1 is more area-balanced.
The water temperature control system 5 has the advantages of simple structure and low cost, can realize the function of heating the liquid water 2, can also realize the function of cooling the liquid water 2, has high automation degree, can form surfing effect in the liquid water 2 through water drainage, increases disturbance of the liquid water 2 in the heat preservation box 1, and increases heat exchange of the liquid water 2 in each region in the heat preservation box 1, so that the liquid water 2 in each region in the heat preservation box 1 can reach water temperature balance more quickly.
Optionally, as shown in fig. 1, a mesh enclosure 513 is further connected to the bottom of the incubator 1, and the mesh enclosure 513 is covered outside the water pump 502, the first heat insulation chamber 504 and the second heat insulation chamber 508. By the isolation function of the net cover 513, the semen storage part 6 or the inflatable floating ball 7 cannot be sucked into the water pump 502 by the water pump 502. The first water outlet pipe 506 and the second water outlet pipe 510 are both positioned in the mesh enclosure 513. As the water at the outlet of the first water outlet pipe 506 is lower; when the second water outlet pipe 510 is used for water outlet, the water temperature at the outlet is higher, and the mesh enclosure 513 is arranged, so that the semen storage part 6 or the inflatable floating ball 7 can not be close to the outlet of the first water outlet pipe 506 and the outlet of the second water outlet, and the semen storage part 6 can not be instantaneously heated to overheat or refrigerated to supercool.
Optionally, as shown in fig. 1, the first water outlet pipe 506 and the second water outlet pipe 510 in this embodiment face upward, that is, the first water outlet pipe 506 and the second water outlet pipe 510 in this embodiment face the tank opening of the heat insulation tank 1, so that the sprayed cooled water or the sprayed heated water is sprayed directly to one side of the tank opening, so as to ensure that the cooling capacity or the heat can be more quickly and evenly dispersed in the liquid water 2 in the heat insulation tank 1.

The inflatable floating ball 7 in this embodiment is actually a rubber sheet, the edge of which is connected to the plastic cover 602 by hot melting, and the inflatable floating ball 7 has an air charging hole in which an air tap is installed. When inflation is required, an inflation member (e.g., an air gun) is used to inject air into the inflatable ball 7 through the air tap, thereby inflating the inflatable ball 7. By controlling the amount of inflation, the volume of the inflatable ball 7 after inflation can be controlled, thereby controlling the buoyancy of the ball in the liquid water 2. After the inflation is completed, the air tap can play a role in blocking and preventing air leakage.

Example 2:
this embodiment provides a water bath type breeding pig semen heat preservation transport case, and it is roughly the same with the water bath type breeding pig semen heat preservation transport case that embodiment 1 provided, and the difference lies in:
a plurality of partition boards 8 are installed in the box body 101, the inner cavity of the box body 101 is divided into a plurality of subchambers by the plurality of partition boards 8, liquid water 2 is filled in each subchamber, and a plurality of semen storage parts 6 are placed in the liquid water 2 in each subchamber.
A water flow window 801 through which water flows is provided in the middle of the partition 8, and each sub-chamber is communicated by means of the water flow window 801. The partition plate 8 is located above the first heat-insulating chamber and the second heat-insulating chamber.
In the transportation process of the transportation box in embodiment 1, particularly when the vehicle is started or braked, water generates strong impact force due to inertia, the activity of sperms is influenced by the impact force, meanwhile, the impact force impacts the shell of the transportation box to excite great spoons, the sealing performance of the box body is greatly improved by the liquid water 2 which is greatly agitated, the sealing performance of the box body is also influenced, and the pressure on the shell of the shell insulation box shell also greatly reduces the service life of the insulation box.
In this embodiment, through setting up baffle 8, the motion that has reduced the water in the box when car starts or brakes forms for the impact force that water formed reduces, has reduced the impact force of water to seminal fluid when braking or starting, and the box inner wall, but to the water bath insulation can, still need guarantee the circulation of incasement water, in order to avoid the local too high of insulation can water temperature, or local temperature is too low, therefore, in this embodiment, still be provided with the rivers window 801 that supplies water circulation in baffle 8, with the help of this rivers window 801, make every subchamber all communicate.
It should be noted that the size of the water flow window 801 in this embodiment is smaller than the size of the semen storage portion 6, that is, the semen storage portion 6 does not enter the water flow window 801.
More preferably, a supporting beam 802 is disposed in the water flow window 801, a sliding hole coaxial with the water flow window 801 is formed in the supporting beam 802, a sliding rod 9 is inserted in the sliding hole in a sliding manner, two ends of the sliding rod 9 are respectively located at two sides of the partition 8, a sealing plate 10 is respectively welded or bolted at two ends of the sliding rod 9, and the sealing plate 10 can cover the water flow window 801 to seal the water flow window 801. In this way, the slide bar 9 can drive two sealing plates 10 to move, when one sealing plate 10 moves to close the water flow window 801, the other sealing plate 10 moves to a position at the maximum distance from the partition 8, and when the other sealing plate 10 moves to close the water flow window 801, the previous sealing plate 10 moves to a position at the maximum distance from the partition 8.
When the transport vehicle starts, under the action of inertia force, the sliding rod 9 and the sealing plate 10 have the characteristic of keeping standing, so that the sealing plate 10 near the vehicle head side moves towards the side near the partition plate 8, and the sealing plate 10 near the vehicle tail side moves towards the side far away from the partition plate 8 until the sealing plate 10 near the vehicle head side seals the water flow window 801, and thus, when the transport vehicle starts, the partition plate 8 and the corresponding sealing plate 10 can further block the liquid water 2 in the adjacent subchambers from flowing, thereby further reducing the surge amplitude of the liquid water 2 in the box 101 when the transport vehicle starts. When the transport vehicle is braked, under the action of inertia force, the sliding rod 9 and the sealing plate 10 have the characteristic of keeping motion, so that the sealing plate 10 positioned near the vehicle tail side moves towards the side close to the partition plate 8, and the sealing plate 10 positioned near the vehicle head side moves towards the side far away from the partition plate 8 until the sealing plate 10 near the vehicle tail side seals the water flow window 801, and thus, when the transport vehicle is braked, the partition plate 8 and the corresponding sealing plate 10 can further block the liquid water 2 in the adjacent subchambers from flowing, thereby further reducing the surge amplitude of the liquid water 2 in the box 101 when the transport vehicle is started.

By spring 12, sealing plate 10 is elastically connected to support beam 802 (i.e., partition 8), it is easily understood that when slide bar 9 slides in the slide hole, one spring 12 on both sides of partition 8 will be compressed by its corresponding sealing plate 10, and the other spring 12 will be stretched by its corresponding other sealing plate 10. In this way, when the transport vehicle runs at a constant speed, the spring 12 will drive the sealing plate 10 for sealing the water flow window 801 to move towards the side far away from the partition plate 8, so that the water flow window 801 is opened, and the liquid water 2 in the adjacent subchamber can circulate to exchange heat when the transport vehicle runs.
More preferably, a water flow gap 1001 is formed on the sealing plate 10, and a spring piece 11 capable of sealing the water flow gap 1001 is further connected to the sealing plate 10, wherein the spring piece 11 is disposed on one side of the sealing plate 10 away from the partition plate 8. Because the sealing plate 10 is a plate body, the sealing plate 10 can reduce the smoothness of the flow of the liquid water 2 in the process of uniform speed running of the transport vehicle, and the above-mentioned water flow notch 1001 can enable the liquid water 2 to flow more smoothly on both sides of the sealing plate 10.
At the moment of starting the transport vehicle, the liquid water 2 and the sealing plate 10 move towards the vehicle tail, so that the sealing plate 10 near the vehicle head side and the liquid water 2 move towards the vehicle tail side, and the liquid water 2 pushes the elastic sheet 11 on the sealing plate 10 near the vehicle head side to rotate so as to seal the water flow notch 1001, and in this state, the sealing plate 10 near the vehicle head side seals the water flow window 801; in the vehicle brake Sun Jian, the liquid water 2 and the sealing plate 10 move toward the vehicle head, so that the sealing plate 10 and the liquid water 2 near the vehicle tail move toward the vehicle head, and the liquid water 2 pushes the elastic sheet 11 on the sealing plate 10 near the vehicle tail to rotate to seal the water flow gap 1001, so that the sealing plate 10 near the vehicle tail seals the water flow window 801 in this state. When the carrier vehicle runs at a constant speed, the elastic piece 11 releases the water flow notch 1001 under the action of elastic force, so that the smoothness of the flow of the liquid water 2 in each subchamber is better during the constant speed running.
