Technical Field

[0001] This utility model relates to the field of whole-domain environmental injury simulation technology, specifically to a whole-domain environmental injury simulation device. Background Technology

[0002] The full-domain environmental injury simulation device is an experimental device that simulates injuries such as thermal shock, blunt impact, collision, compression, puncture, and fragmentation under different temperature, humidity, air pressure, and oxygen content environments. With the continuous advancement of technology, injury simulation devices may become more advanced and interactive. For example, the application of simulated reality and augmented reality technologies can provide a more realistic and immersive experience. In addition, the device may combine data analysis and simulation algorithms to more accurately predict and simulate mechanical injury processes, providing a more scientific basis for the formulation and improvement of safety measures.

[0003] The applicant discovered through a search that a Chinese patent, "A Tissue Fixation Experiment for Simulating Shock Wave Injury," with publication (announcement) number "CN214122245U," mainly utilizes a suspension bracket located at the shock tube outlet, a storage device for holding tissue cultures, and a first and second fixing frame sequentially mounted on the suspension bracket to clamp the storage device. The first and second fixing frames are respectively provided with clearance holes for exposing the tissue cultures.

It can simulate various scenarios, perform qualitative and quantitative processing of simulation data, and the entire process is computer-controlled, making it simple to operate. The specific details are as follows:

[0019] 1. By setting up a simulation chamber, fixed port plate, first lead screw, pressure plate, placement groove, pressure sensor, moving sleeve, second lead screw, fixed shell, gear, motor, stabilizing cylinder, and slide, the test sample is placed in the simulation chamber. Starting the motor drives the pressure plate to move, which, in conjunction with the push shell, facilitates the compression of the test sample.

A control console 18 is set on the front of the simulation cabin 1. A control system 19 is installed on the top of the control console 18.

[0036] When in use, the test sample is placed in the simulation chamber 1, and the motor 12 is started, which eventually drives the pressure plate 5 to move. Together with the push shell 4, it facilitates the squeezing of the test sample. This equipment can be used to conduct simulation experiments of animal injuries, which are equivalent to the simulation of crush injuries and impact injuries suffered by humans at different altitudes and terrains. The simulation scenarios are diverse, and the simulation data is qualitatively and quantitatively processed. The whole process is completed by computer control and is easy to operate.

The upper part of the connecting pipe 22 near the air cannon device 21 is connected to a projectile inlet 23. A one-way valve 24 is installed on the outside of the connecting pipe 22.

[0038] The second lead screw 9 has an internal mounting groove, and the connecting pipe 22 is located inside the mounting groove. The second lead screw 9 is rotatably connected to the connecting pipe 22. The side of the connecting pipe 22 away from the air cannon device 21 is slidably connected to the telescopic pipe 25.

The telescopic pipe 25 is rotatably connected to the mounting bearing 26. The interior of the telescopic pipe 25 is connected to the interior of the simulation cabin 1.

[0039] When impact damage simulation is required, the object is placed inside the simulation chamber 1, the inlet 23 is opened, the test projectile is placed into the connecting pipe 22 through the inlet 23, the one-way valve 24 is opened, the air cannon device 21 is started, and the strong airflow of compressed gas ejected by the air cannon device 21 propels the projectile through the connecting pipe 22 and the telescopic pipe 25 and ejects it, so that the projectile impacts the object under test, thus facilitating the simulation of impact damage.

[0040] When different air pressure conditions need to be simulated, simply connect the air inlet on the simulation chamber 1 to the air extraction device and extract the air from the simulation chamber 1 to different degrees to meet the testing requirements. This facilitates testing of the device at different altitudes (i.e., different air pressures and different oxygen contents) and at different temperatures, thus improving the comprehensiveness of the device's testing capabilities.

[0042] Working principle:

[0043] Before using the full-domain environmental injury simulation device, it is necessary to check the overall condition of the device to ensure that it can function normally. Figure 1 - Figure 5As shown, when using this device, the test sample is placed in the simulation chamber 1, and the handle 15 is turned. The handle 15 rotates the first lead screw 3. Under the action of the fixed port plate 2, the first lead screw 3 drives the push shell 4 to move, moving the test sample in the simulation chamber 1 to contact the pressure plate 5. At this time, the motor 12 is started. Under the action of the two gears 11, the motor 12 drives the second lead screw 9 to rotate. The second lead screw 9 causes the moving sleeve 8 to move stably under the action of the slide groove 14. The moving sleeve 8 drives the pressure plate 5 to move, squeezing the test sample.

[0044] The pressure sensor 7 on the pressure plate 5 detects the pressure value between the test sample and the pressure plate 5 and transmits the data to the control system 19. By controlling the rotation speed of the motor 12, the squeezing force of the pressure plate 5 on the test sample can be controlled, thereby obtaining the deformation of the test sample under different squeezing forces.

[0045] When impact damage simulation is required, the object is placed inside the simulation chamber 1, the inlet 23 is opened, the test projectile is placed into the connecting pipe 22 through the inlet 23, the one-way valve 24 is opened, the air cannon device 21 is started, and the strong airflow of compressed gas ejected by the air cannon device 21 propels the projectile through the connecting pipe 22 and the telescopic pipe 25 and ejects it, so that the projectile impacts the object under test, thus facilitating the simulation of impact damage.

[0046] Meanwhile, the temperature inside the simulation chamber 1 is controlled by the cooling device 27, and the temperature is transmitted to the control system 19 through the temperature sensor 28, which makes it easy for the test personnel to control different temperature tests. When different air pressure conditions need to be simulated, the air inlet on the simulation chamber 1 is connected to the air extraction device to extract air from the simulation chamber 1 to different degrees, which can meet the test requirements.

[0047] This equipment can be used to conduct simulated experiments on animal injuries, which are equivalent to the simulation of crush injuries and impact injuries suffered by humans at different altitudes and terrains. The simulation scenarios are diverse, and the simulation data is processed qualitatively and quantitatively. The entire process is controlled by a computer, and the system has interfaces for future structural and communication upgrades.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
