Chinese patent application number CN201210394749.X discloses a fully automatic Kenan experimental system for determining the sensitivity of solid and liquid substances to high heat under highly enclosed conditions. The system consists of six parts: air distribution / intake system, combustion system, cooling and purge system, emergency fire extinguishing system, observation and video recording system, and central control system. The combustion system, cooling and purge system and emergency fire extinguishing system are assembled together and installed in the explosion-proof laboratory of the Kenan experimental device.

[0003] The designer found that the above-mentioned Kenan test system, although it can perform a sealed combustion test on the sample to be tested, has a large installation area because it is a system mechanism. From its structural diagram, it can be seen that the various mechanisms of the system are scattered, so it will take up a large space during actual installation. Although the system is large, it still lacks a sample preparation mechanism for the substance to be tested, and the detection method is too single during the closed combustion test, especially when the liquid substance to be tested explodes with the sample preparation tube, the presentation effect is not intuitive. How to monitor the power consumption of the corresponding equipment itself has also become one of the issues to be considered in the experiment. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model has a simple and reasonable structural design, is easy to make, has strong practicality, and is very easy to promote and use. The electricity monitoring system has two-way metering with one input and two outputs, one for connecting the metering light and the other for connecting the metering air conditioner, and simplifies the control. The whole system has the characteristics of high reliability, small size, light weight, beautiful appearance, easy installation, cost saving, simple construction and wiring, and convenient later maintenance. Compared with the existing system equipment, the Kenan test device of this structure is composed of three parts: left, right, and top. The overall structure is more compact. In actual use, the installation space is smaller, saving the installation area, but still has a complete experimental effect, simple structure, low manufacturing cost, and easy maintenance.

[0016] 2. Compared with the existing system equipment, the left side of the Kenan test device of this structure is the sample making part, which is composed of an electric cylinder and a sample making cavity. The accessory sample making tube is filled with materials in this sample making cavity, and the electric cylinder is used to compact the materials. The compressed material sample can be quickly made. The electric cylinder sample making method replaces the existing zipper hanging hammer sample making method. Therefore, it can be seen that the electric cylinder sample making method is more convenient and quick.

[0017] 3. Compared with the existing system equipment, the Kenan test device of this structure is provided with a test chamber on the top right side, and two spring-type clamps are provided in the test chamber, and two sample tubes compacted with solid materials can be inserted into the clamps. If the sample tube explodes when the bottom is heated, the spring clamp will buffer it and reduce the damage to the test chamber. Therefore, the clamp used to clamp the sample tube has a reasonable structural design, and two sample tubes with different materials added can be compared after being broken by heat. For example, if the breakage of one sample tube is greater than that of the other sample tube, it proves that the material performance of the severely broken sample tube is lower than that of the other material. The solid material has comparative properties when tested in a sealed heated environment. Of course, if one sample tube is not broken or cracked, it proves that the performance of this material is relatively stable.

[0018] 4. The above test chamber can also be used to test two different types of liquid materials. It is also comparative when tested in a sealed heated environment. Two sample tubes are loaded with two different and equal amounts of materials, and each is placed in two spring clamp seats. When the two sample tubes are broken due to continuous heating, the splashed liquid materials will appear on two corrugated rubber plates. According to the splashing materials on the two corrugated plates, the performance of the two liquid materials in the same test chamber can be judged. Of course, if one sample tube is not broken or cracked, it proves that the performance of this material is relatively stable.

[0019] 5. The test chamber also has the characteristic of spatial variation. After adjusting the bottom screw, the 4. variation in the test chamber can be adjusted up and down. The space of the test chamber can be changed through its adjustment action. Therefore, when testing the performance of two materials, in order to improve the diversity of testing, the temperature in the chamber and the heating speed can be changed by changing the space of the test chamber. The flexibility and practicality of the test chamber are improved. BRIEF DESCRIPTION OF THE DRAWINGS

The variable plate 34 is located in the test chamber 11 in a manner of sliding up and down, such as Figure 1 , Figure 6As shown, the high-energy igniter 22 is located at the bottom of the test chamber 11, forming an ignition structure at the bottom of the test chamber 11, and the movable plate 16 can change the space of the test chamber 11 after the variable plate 34 is adjusted up and down. If the space of the test chamber 11 becomes smaller, the high-energy igniter 22 will spray fire upwards, which will cause the test chamber 11 to heat up quickly. On the contrary, if the space of the test chamber 11 becomes larger, the high-energy igniter 22 will spray fire upwards, which will cause the test chamber 11 to heat up slowly.

[0060] A partition 29 is welded to the bottom of the test chamber 11, and a temperature sensor 24 is installed on the top of the partition 29. The temperature sensor 24 is electrically connected to the thermocouple controller 13 to detect the temperature of the test chamber 11 and feed back the temperature value to the display screen 33. The electrical connection line passes through the variable plate 34 and is glued to the perforation of the variable plate 34. The length of the electrical connection line is long enough so that the wiring harness is not affected when the variable plate 34 moves up and down. The variable plate 34 is located at the top of the test chamber 11 to form a relatively closed test chamber. Two spring clamp seats 28 are installed on the partition 29. The bottom clamp cavity of the partition 29 is provided with front and rear fire holes 30. A ceramic tube 23 is also embedded in the fire hole 30. The high-energy igniter 22 is installed on the ceramic tube 23, and the flame nozzle of the high-energy igniter 22 is located at the bottom side of the spring clamp seat 28, which can heat the sample preparation tube 6 placed in the spring clamp seat 28 from the bottom. Figure 8 , Fig. 9 As shown, two spring clamp seats 28 are symmetrically arranged front and back according to the temperature sensor 24. The two spring clamp seats 28 are used to clamp two sample tubes 6 filled with materials. It can be seen from the figure that the spring clamp seat 28 is composed of an inner spring and two arc-shaped plates on the outer side of the spring, wherein a spring 31 is welded to the outside of the arc-shaped plate, and the outer end of the spring 31 is welded to the inner wall of the test chamber 11. Therefore, when the bottom of the sample tube 6 clamped in the two spring clamp seats 28 is heated and bursts, the spring structure can form a buffer to retain the fragments as much as possible in the clamp seat structure. After the two sample tubes 6 with equal amounts of materials injected are heated and burst, the properties of the materials in the two tubes can be judged according to their bursting conditions. The material sample in the sample tube 6 can be a liquid material or a compressed solid material.

[0061] Specific: such as Figure 8 , Fig. 9 as well as Fig.10As shown, a first detection seat 25 and a second detection seat 26 are welded on the bottom surface of the variable plate 34, and the first detection seat 25 and the second detection seat 26 correspond to two spring clamp seats 28 respectively. When the material in the sample tube 6 clamped in the two spring clamp seats 28 is liquid, their bottoms are slowly heated, and when they burst, liquid will splash on their respective corresponding detection seat structures. Since a detection plate 27 is glued to the inner end surfaces of the first detection seat 25 and the second detection seat 26, and the detection plate 27 is a rubber plate with a texture on the inner surface, the liquid material splashed on the texture of the detection plate 27 must have inconsistent regional ranges. For example, when more liquid material splashes on the first detection seat 25, more liquid will be retained on the detection plate 27 here, which proves that the performance change of the liquid material in the spring clamp seat 28 corresponding to the first detection seat 25 is greater than that of the liquid material sample in the other spring clamp seat 28.

[0062] Specific: such as Figure 6 , Figure 7 As shown, a bearing 17 is welded on the right side of the bottom surface of the test chamber 11, and a screw 18 is installed on the bearing 17. A handwheel 19 is welded on the bottom end of the screw 18. The bottom end of the movable plate 16 is bent inwardly, and its inner bending section is matched with the screw 18 through a threaded sleeve 20. When the handwheel 19 is turned, the screw 18 will rotate, thereby causing the movable plate 16 matched with the screw 18 to move up and down, thereby causing the variable plate 34 on the top end of the movable plate 16 to adjust up and down in the test chamber 11. Since the first detection seat 25 and the second detection seat 26 are also located on the variable plate 34, the variable plate 34 can not only change the space of the test chamber 11 after adjustment, but also change the position height of the first detection seat 25 and the second detection seat 26. After they are raised, it is convenient to observe the situation where liquid samples are left on the texture of the detection plate 27. Therefore, the installation position design of the first detection seat 25 and the second detection seat 26 is reasonable, and the dual-function structure design is ingenious.

[0063] The ignition structure in this design is the existing technology of the Kenan test machine (not described here). After pressing the ignition controller 12, the electronic ignition and the external gas input will cause the high-energy igniter 22 to ignite. The two high-energy igniters 22 ignite at the same time. At this time, the sample tube 6 containing the same volume of liquid material can be directly inserted into the two spring clamp seats 28. The ignited high-energy igniter 22 heats the bottom of the two sample tubes 6. When their bottoms are slowly heated and burst, liquid will splash on their corresponding detection seat structures. Since a detection plate 27 is glued to the inner end surface of the first detection seat 25 and the second detection seat 26, the detection plate 27 is a rubber plate with a texture on the inner surface. Therefore, the liquid material splashed on the texture of the detection plate 27 must have inconsistent regional ranges. For example, when more liquid material splashes on the first detection seat 25, more liquid will be retained on the detection plate 27 here, which proves that the performance change of the liquid material in the spring clamp seat 28 corresponding to the first detection seat 25 is greater than that of the liquid material sample in the other spring clamp seat 28.

[0064] When the material to be tested is solid, two sample tubes 6 filled with solid materials are respectively inserted into the sample chamber 3. After the electric cylinder 7 of the existing power control technology is energized, its action rod extends downward, and the sample hammer 9 at the bottom end is pressed into the sample tube 6 inserted in the drop seat 5 with the bottom thin end. The thin end of the sample hammer 9 pressed downward will squeeze and compress the solid material. Then, the two prepared sample tubes 6 are respectively inserted into the two spring clamp seats 28 to observe the changes of the sample tubes 6. If the sample tube 6 bursts, it proves that the organization of the solid material filled inside has changed more strongly. The performance of the material to be tested can be judged according to the bursting of the sample tube 6.

[0065] Of course, during the above-mentioned experimental test, if one of the sample tubes 6 is not broken or cracked, it proves that the performance of this material is relatively stable. Similarly, if they are just cracked, it is only necessary to observe the thin-wall cracks of the two sample tubes 6. Larger cracks prove that the material performance is more active, and on the contrary, the material performance is relatively stable.
