Description

Technical Field

[0001] The present invention relates to a 4D imaging system, in particular to an ultra-high temperature infinite rotation 4D imaging system. Background Art

[0002] The ultra-high-temperature, infinite-rotation 4D imaging system is a complex system that integrates extreme environmental adaptability, high-precision motion control, and multi-dimensional imaging technology. Its technical implementation is challenging and its application scenarios are well-defined, as shown below: 1. Ultra-high temperature tolerance. Conventional metals (such as aluminum alloys and steel) will soften, creep, or oxidize at temperatures above 500°C, leading to structural failure. Electronic devices (such as chips and sensors) may be permanently damaged at temperatures above 200°C. 2. Infinite rotation mechanism. Traditional testing machines, when rotating in one direction at infinite angles, can cause entanglement of various cables and pipes, leading to cable breakage. Furthermore, the rotation process can cause product quality imbalance and vibration, affecting imaging accuracy.

[0003] Traditional testing devices also have significant shortcomings in observing internal material damage and deformation at high temperatures and in real time, failing to meet the needs of scientific research fields such as aerospace. Specifically, traditional testing devices use room-temperature testing, 1×360-degree rotation, and 3D imaging when testing on industrial CT. This testing method cannot meet the current requirements of scientific research fields such as aerospace to apply loads to materials at high temperatures of 1500°C while observing internal material damage and deformation in real time. They can only stack pictures to form a 3D stereo image, and cannot achieve 4D video animation to observe the internal damage process of the material. 2. Other testing devices on the market use ex-situ testing. That is, in other laboratories, large testing machines are used to heat the material to 1500°C, stretch it to a fixed force, hold it for a period of time, and then disassemble the test piece and install it on an industrial CT for scanning and imaging. Such testing cannot effectively study material properties under the real-time and simultaneous application of multiple load fields, cannot simulate the material's operating conditions under actual service conditions, and cannot provide effective data support for the research and development of new materials. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide an ultra-high temperature infinite rotation 4D imaging system for use in tensile, compression, and torsion tests of materials in the radiation fields of industrial CT, synchrotron radiation light sources, etc. at ultra-high temperatures of 1500°C. It can also realize an n×360-degree infinite rotation test system, effectively avoiding the entanglement problem of cables and water-cooling pipes.

[0005] The present invention provides the following technical solutions:

[0006] An ultra-high-temperature, infinitely rotating 4D imaging system includes a system body mounted on a CT turntable. When the CT turntable rotates infinitely through n×360°, X-rays from one side of the CT turntable are used to perform n×360°, multiple-cycle, infinitely rotating 4D scanning imaging of a sample within the system body. The system body includes a water slip ring unit, a drive and electric slip ring unit, a high-temperature load-bearing barrel unit, and a hydroelectric slip ring unit. The sample is positioned within the high-temperature load-bearing barrel unit and is subjected to ultra-high-temperature heating by the high-temperature load-bearing barrel unit. The drive and electric slip ring unit is located at the bottom of the high-temperature load-bearing barrel unit and is used to apply tensile, compressive, or torsional forces to the sample while also being able to rotate infinitely through n×360° along with the water slip ring unit at the bottom. The hydroelectric slip ring unit is located at the top of the high-temperature load-bearing barrel unit and, together with the water slip ring unit, is used to provide cooling liquid to the rotating system body during high-temperature testing to prevent damage to the system body due to excessive heating.

[0007] In practical applications, the specimen is mounted in a high-temperature load-bearing barrel unit. The water slip ring unit, drive and electric slip ring unit, high-temperature load-bearing barrel unit, and water-electric slip ring unit are installed sequentially from bottom to top and integrally mounted on the CT turntable. Rotation of the CT turntable drives the system itself. During rotation, the specimen, driven by the drive and electric slip ring units, undergoes tension, compression, or twisting. This enables 4D animation of the specimen as it rotates continuously through n×360°. This provides researchers with the most realistic and intuitive real-time visualization of the material's internal damage process, rather than simply outputting a static 3D image that lacks the effect of animated video of the damage process. Because the test must be conducted at a high temperature of 1500°C, water cooling structures are installed at both the top and bottom of the system to ensure safe operation of the entire equipment at high temperatures. The integration of the water and electric functions for unlimited n×360° rotation contributes to the overall advantages of the equipment's light weight and low height, enabling its integration into an industrial CT cabin.

[0008] Preferably, the water slip ring unit includes a bottom plate, a water slip ring outer cylinder, and a water slip ring core shaft. The bottom plate is installed on the CT turntable. The bottom end of the water slip ring core shaft is connected to the bottom plate, and the top end is connected to the drive and electric slip ring unit. The water slip ring outer cylinder is configured outside the water slip ring core shaft. The water slip ring outer cylinder is configured with water inlet 1 and water outlet 3. The water slip ring core shaft is configured with water inlet 1, water inlet 2, water outlet 2 and water outlet 3. There are two groups of annular sealed cavities between the water slip ring core shaft and the water slip ring outer cylinder. The water inlet 1 and the water inlet 1 are connected to the first group of sealed cavities, and the outlets are connected to the water inlet 1 and the water outlet 2. Water nozzle three and water outlet three are connected to the second group of sealed cavities. The water outlet pipe of the external chiller is connected to water inlet nozzle one. The coolant enters the first group of sealed cavities through water inlet nozzle one, then flows to water inlet two through water inlet one, and flows out through water inlet nozzle two installed on water inlet two. Water inlet nozzle two is connected to water inlet nozzle three of the water-cooled plate in the drive and electric slip ring unit through a water pipe. Inside the water-cooled plate, the coolant flows out from water outlet nozzle one. The water outlet nozzle one is connected to water outlet nozzle two installed on water outlet two through a water pipe. Then, the coolant flows to water outlet three through blowing water nozzle two and flows out from blowing water nozzle three through the second group of sealed cavities.

[0009] Since the water slip ring core shaft and the water slip ring outer cylinder are rotationally sealed, the water slip ring core shaft is connected to the base plate, and the rotation of the base plate will drive the water slip ring core shaft to rotate, while the water slip ring outer cylinder does not move, so the water slip ring core shaft can rotate infinitely while the water slip ring outer cylinder does not move. In this way, the external water pipes do not need to rotate with the equipment, and n×360° infinite rotation can be completed.

[0010] Preferably, the drive and electric slip ring unit includes a motor load sensor assembly installed on the guide plate. The motor load sensor assembly is a component used to monitor the load borne by the motor during operation. The motor load sensor assembly is connected to a water-cooled plate, and the water-cooled plate is connected to a lower pressure rod via a lower connecting rod. The upper pressure rod is located above the lower pressure rod and is used to cooperate with the lower pressure rod to position the two ends of the sample. At this point, when the drive and electric slip ring unit is to realize the function of applying a torsional force to the sample, it is only necessary to start the motor load sensor assembly after the sample is positioned. Since the motor of the motor load sensor assembly has a driving rotation effect, the lower pressure rod can drive the bottom end of the sample to twist relative to the top end positioned by the upper pressure rod. At the same time, the sensor module of the motor load sensor assembly can also collect the magnitude of the torsional force.

[0011] Preferably, the drive and electric slip ring unit also includes a rotary motor, a nut and a screw, the water slip ring core shaft is connected to the stator of the rotary motor, the nut is connected to the rotor of the rotary motor assembly, and the screw is connected to the guide plate. When the nut rotates forward or reversely with the rotor, the screw in the nut is driven to move upward or downward. The guide plate is used to ensure that the screw always moves in a straight line. At this point, after starting the rotary motor, the rotation of the rotor drives the screw to rise and fall, and then drives the lower pressure rod to support the sample to expand or reduce the spacing relative to the upper pressure rod to achieve stretching or compression of the sample, and the motor load sensor assembly can also collect the magnitude of the stretching or compression force.

[0012] Preferably, the rotating motor is installed in the electric slip ring inner cylinder, and an electric slip ring outer cylinder is further provided outside the electric slip ring inner cylinder. The electric slip ring inner cylinder can perform n×360° infinite rotation relative to the electric slip ring outer cylinder. The electric slip ring inner cylinder is also equipped with a bearing cylinder for covering the guide plate, motor load sensor assembly, water cooling plate, lower connecting plate, lower pressure rod, sample, and upper pressure rod. The bearing cylinder is also equipped with a clamp upper cover connected to the lower pressure rod. The function of the electric slip ring is to realize continuous power, signal or data transmission between the rotating component and the fixed component, while avoiding the problem of traditional cable entanglement or breakage. The cables of the motor load sensor assembly and the rotating motor are connected to the electric slip ring inner cylinder, and then the cables are led out through the electric slip ring outer cylinder. In this way, it can be achieved that: when the CT turntable rotates infinitely , which can drive the water slip ring core shaft to rotate, thereby driving the entire bearing cylinder, rotating motor, screw rod, nut, guide plate, motor load sensor assembly, water cooling plate, lower connecting plate, lower pressure rod, specimen, upper pressure rod, and fixture cover to rotate together, while the electric slip ring outer cylinder is stationary and does not rotate. At the same time, the cable signals of the rotating motor and motor load sensor assembly are transmitted to the control system. At this point, when the entire system is rotating, only the electric slip ring outer cylinder and the water slip ring outer cylinder are stationary, thereby integrating the infinite rotation n×360° functions of water and electricity, and playing the advantages of light overall weight and low height of the equipment, which can be matched with the industrial CT cabin. At the same time, the coolant used for cooling can also effectively cool the driving and monitoring components, ensuring the safe use of the entire equipment at high temperatures.

[0013] Preferably, the high-temperature bearing barrel unit includes an outer insulation layer and an inner insulation layer located on the inner side of the bearing tube, and a heating body is installed on the upper cover of the clamp to perform ultra-high temperature heating on the sample positioned by the upper pressure rod and the lower pressure rod. At this point, when the positive and negative poles of the heating body are connected to an external power supply, the heating body itself will become hot. As the external current increases, the heat will also increase, so that the sample can be heated. In order to ensure temperature stability, the inner insulation layer and the outer insulation layer installed outside the heating body can prevent the internal heat from diffusing outward. In order to ensure that the other components are not burned at high temperatures, a water cooling channel is also provided in the upper cover of the clamp.

[0014] Preferably, the hydroelectric slip ring unit comprises a hydroelectric slip ring outer barrel, a hydroelectric slip ring inner barrel and a hydroelectric slip ring core shaft which are sequentially arranged from the outside to the inside; the fixture upper cover is connected to the hydroelectric slip ring inner barrel through a transition piece; the hydroelectric slip ring inner barrel is installed between the hydroelectric slip ring outer barrel and the hydroelectric slip ring core shaft for connection; an annular water inlet cavity and an annular water outlet cavity are further provided between the hydroelectric slip ring inner barrel and the hydroelectric slip ring core shaft; a second water inlet nozzle communicating with the annular water inlet cavity and a second water outlet nozzle communicating with the annular water outlet cavity are provided at the bottom end of the hydroelectric slip ring inner barrel; a first water inlet nozzle communicating with the annular water inlet cavity and a first water outlet nozzle communicating with the annular water outlet cavity are further provided at the top end of the hydroelectric slip ring core shaft;

[0015] The cooling water flows into the water cooling channel from the third water inlet on the transition piece, and then flows out from the third water outlet on the transition piece. The third water inlet is connected to the second water inlet with a water pipe, and the second water inlet is connected to the first water inlet through the hydroelectric slip ring core shaft, and the first water inlet is connected to the water outlet of the external water cooler. The third water outlet is connected to the second water outlet with a water pipe, and the second water outlet is connected to the first water outlet through the hydroelectric slip ring core shaft, and the first water outlet is connected to the return water outlet of the external water cooler, thus realizing a water circulation cooling system loop.

[0016] Preferably, the transition piece is further provided with a third negative electrode terminal connected to the heating negative electrode and a third positive electrode terminal connected to the heating positive electrode, the inner barrel of the hydroelectric slip ring is further provided with a second negative electrode terminal connected to the third negative electrode terminal and a second positive electrode terminal connected to the third positive electrode terminal, and the outer barrel of the hydroelectric slip ring is further provided with a first negative electrode terminal connected to the second negative electrode terminal and a first positive electrode terminal connected to the second positive electrode terminal;

[0017] When the inner barrel of the hydroelectric slip ring, the second water inlet, the second water outlet, the second positive terminal, the second negative terminal, the third positive terminal, the third negative terminal, the third water inlet and the third water outlet rotate infinitely with the system, the outer barrel of the hydroelectric slip ring, the hydroelectric slip ring core shaft, the first negative terminal, the first positive terminal, the first water inlet and the first water outlet are all stationary. This ensures that the main electrode cables connected to the outside of the system and the inlet and outlet water pipes of the water chiller also remain stationary, so that the equipment can rotate infinitely while the external cables and water pipes remain stationary to avoid entanglement.

[0018] The beneficial effects of the present invention are:

[0019] 1. The system of the present invention can achieve a high temperature function of 1500°C while meeting the optimal resolution;

[0020] 2. The system of the present invention can achieve n × 360-degree continuous rotation and realize 4D animation imaging, which can provide researchers with the most realistic and intuitive internal damage process of the material in real time, rather than simply outputting a static 3D image as the result, which lacks the animation video effect of the damage process;

[0021] 3. The system of the present invention can realize vacuuming and filling with inert gas, effectively protecting the sample from oxidation at high temperature;

[0022] 4. The water cooling unit equipped in the system of the present invention can effectively protect the entire set of equipment for safe use at high temperatures, and integrates the infinite rotation n×360-degree functions of water and electricity, which has the advantages of light overall weight and low height of the equipment and can be matched with the industrial CT cabin.

[0033] Example 1

[0034] like Figure 1-2 As shown, an ultra-high temperature infinite rotation 4D imaging system, in this embodiment, includes a system body mounted on a CT turntable 1. When the CT turntable 1 rotates infinitely through n×360°, an X-ray 2 on one side of the CT turntable 1 is used to perform n×360° multiple cycles of infinite rotation 4D scanning imaging of a sample 7 within the system body. The system body includes a water slip ring unit 3, a drive and electric slip ring unit 4, a high-temperature load-bearing barrel unit 5, and a hydroelectric slip ring unit 6. The sample 7 is positioned in the high-temperature load-bearing barrel unit 5 and is subjected to ultra-high temperature heating by the high-temperature load-bearing barrel unit 5. The drive and electric slip ring unit 4 is located at the bottom of the high-temperature load-bearing barrel unit 5 and is used to apply tensile, compressive, or torsional forces to the sample 7 while also being able to rotate infinitely through n×360° along with the water slip ring unit 3 at the bottom. The hydroelectric slip ring unit 6 is located at the top of the high-temperature load-bearing barrel unit 5 and, together with the water slip ring unit 3, is used to provide cooling liquid to the rotating system body during high-temperature testing to prevent damage to the system body due to excessive heating.

[0035] In actual application, specimen 7 is installed in the high-temperature load-bearing barrel unit 5. The water slip ring unit 3, drive and electric slip ring unit 4, high-temperature load-bearing barrel unit 5, and water-electric slip ring unit 6 are installed sequentially from bottom to top and integrally mounted on the CT turntable 1. Rotation of the CT turntable 1 drives the system body. During rotation, specimen 7 is stretched, compressed, or twisted under the drive and electric slip ring unit 4. This achieves 4D animation imaging of specimen 7 during its continuous rotation of n×360°. This provides researchers with the most realistic and intuitive real-time visualization of the material's internal damage process, rather than simply outputting a static 3D image as a result, which lacks the effect of animated video of the damage process. Because the test needs to be conducted at a high temperature of 1500°C, water cooling structures are installed at the top and bottom of the system body to ensure safe use of the entire equipment at high temperatures. The integration of the infinite n×360° rotation functions of water and electricity contributes to the advantages of overall light weight and low height, allowing for integration into an industrial CT cabin.

[0036] Example 2

[0037] like Figure 3-5 As shown, an ultra-high temperature infinite rotation 4D imaging system is further defined based on Example 1 in this embodiment. The water slip ring unit 3 includes a base plate 31, a water slip ring outer cylinder 32, and a water slip ring core shaft 33. The base plate 31 is mounted on the CT turntable 1. The bottom end of the water slip ring core shaft 33 is connected to the base plate 31, and the top end is connected to the drive and electric slip ring unit 4. The water slip ring outer cylinder 32 is configured outside the water slip ring core shaft 33. The water slip ring outer cylinder 32 is provided with a water inlet 1 34 and a water outlet 35. The water slip ring core shaft 33 is provided with a water inlet 1 331, a water inlet 2 332, a water outlet 2 333 and a water outlet 334. There are two sets of annular sealed cavities between the water slip ring core shaft 33 and the water slip ring outer cylinder 32. The water inlet 1 34 and the water outlet 35 are connected to each other. The water inlet 331 is connected to the first group of sealed cavities, the water outlet 35 and the water outlet 334 are connected to the second group of sealed cavities, and the outlet pipe of the external chiller is connected to the water inlet 34. The coolant enters the first group of sealed cavities through the water inlet 34, then flows to the water inlet 332 through the water inlet 331, and flows out through the water inlet 36 installed on the water inlet 332. The water inlet 36 is connected to the water inlet 3 of the water-cooled plate 43 in the drive and electric slip ring unit 4 through a water pipe. In the water-cooled plate 43, the coolant flows out from the water outlet 1, and the water outlet 1 is connected to the water outlet 37 installed on the water outlet 333 through a water pipe. Then, the coolant flows to the water outlet 3 334 through the water blowing nozzle 2 and flows out from the water blowing nozzle 3 through the second group of sealed cavities.

[0038] Since the water slip ring core shaft 33 and the water slip ring outer cylinder 32 are rotationally sealed, the water slip ring core shaft 33 is connected to the base plate 31. The rotation of the base plate 31 will drive the water slip ring core shaft 33 to rotate, and the water slip ring outer cylinder 32 will not move. The water slip ring core shaft 33 can rotate infinitely while the water slip ring outer cylinder 32 can not move. In this way, the water pipes connected to the outside do not need to rotate with the equipment, and n×360° infinite rotation can be completed.

[0039] like Figure 6 As shown, the drive and electric slip ring unit 4 includes a motor load sensor assembly 42 installed on the guide plate 41. The motor load sensor assembly 42 is a component used to monitor the load borne by the motor during operation. The motor load sensor assembly 42 is connected to a water-cooled plate 43, and the water-cooled plate 43 is connected to a lower pressure rod 45 through a lower connecting rod 44. The upper pressure rod 46 is located above the lower pressure rod 45 and is used to cooperate with the lower pressure rod 45 to position the two ends of the sample 7. At this point, when the drive and electric slip ring unit 4 is to realize the function of applying a torsional force to the sample 7, it is only necessary to start the motor load sensor assembly 42 after the sample 7 is positioned. Since the motor of the motor load sensor assembly 42 has a driving rotation effect, the lower pressure rod 45 can drive the bottom end of the sample 7 to twist relative to the top end positioned by the upper pressure rod 46. At the same time, the sensor module of the motor load sensor assembly 42 can also collect the magnitude of the torsional force.

[0040] The drive and electric slip ring unit 4 also includes a rotating motor 47, a nut 48 and a screw 49. The water slip ring core shaft 33 is connected to the stator of the rotating motor 47, the nut 48 is connected to the rotor of the rotating motor 47 assembly, and the screw 49 is connected to the guide plate 41. When the nut 48 rotates forward or reversely with the rotor, it drives the screw 49 in the nut 48 to move upward or downward. The guide plate 41 is used to ensure that the screw 49 always moves in a straight line. At this point, after starting the rotating motor 47, the rotation of the rotor drives the screw 49 to rise and fall, and then drives the lower pressure rod 45 to support the sample 7 relative to the upper pressure rod 46 to expand or reduce the spacing, so as to achieve stretching or compression of the sample 7, and the motor load sensor assembly 42 can also collect the magnitude of the stretching or compression force.

[0041] The rotating motor 47 is installed in the electric slip ring inner cylinder 413, and the electric slip ring outer cylinder 412 is also provided outside the electric slip ring inner cylinder 413. The electric slip ring inner cylinder 413 can rotate infinitely n×360 degrees relative to the electric slip ring outer cylinder 412. The electric slip ring inner cylinder 413 is also equipped with a supporting cylinder 410 for covering the guide plate 41, the motor load sensor assembly 42, the water-cooling plate 43, the lower connecting plate, the lower pressure rod 45, the sample 7, and the upper pressure rod 46. The supporting cylinder 410 is also equipped with a clamp upper cover 411 connected to the lower pressure rod 45. The function of the electric slip ring is to realize continuous power, signal or data transmission between the rotating component and the fixed component, while avoiding the problem of traditional cable entanglement or breakage. The cables of the motor load sensor assembly 42 and the rotating motor 47 are connected to the electric slip ring inner cylinder 413, and then the cables are led out through the electric slip ring outer cylinder 412. In this way, it can be achieved: on the CT turntable 1 without When the rotation is limited, the water slip ring core shaft 33 can be driven to rotate, thereby driving the entire supporting cylinder 410, rotating motor 47, screw 49, nut 48, guide plate 41, motor load sensor assembly 42, water cooling plate 43, lower connecting plate, lower pressure rod 45, sample 7, upper pressure rod 46, and fixture cover 411 to rotate together, while the electric slip ring outer cylinder 412 does not rotate. At the same time, the cable signals of the rotating motor 47 and the motor load sensor assembly 42 are transmitted to the control system. At this point, when the entire system rotates, only the electric slip ring outer cylinder 412 and the water slip ring outer cylinder 32 are stationary, thereby realizing the integration of the infinite rotation n×360° functions of water and electricity, and achieving the advantages of light overall weight and low height of the equipment, which can be matched with the industrial CT cabin. At the same time, the cooling liquid used for cooling can also effectively cool the driving and monitoring components, ensuring the safe use of the entire equipment at high temperatures.

[0042] like Figure 7 As shown, the high-temperature bearing barrel unit 5 includes an outer insulation layer 51 and an inner insulation layer 52 located on the inner side of the bearing tube 410, and a heating body 53 is installed on the clamp cover 411 to perform ultra-high temperature heating on the sample 7 positioned by the upper pressure rod 46 and the lower pressure rod 45. At this point, when the positive and negative poles of the heating body 53 are connected to the external power supply, the heating body 53 itself will become hot. As the external current increases, the heat will also increase, so that the sample 7 can be heated. In order to ensure temperature stability, the inner insulation layer 52 and the outer insulation layer 51 installed outside the heating body 53 can prevent the internal heat from diffusing outward. In order to ensure that the other components are not burned at high temperatures, a water cooling channel is also provided in the clamp cover 411.

[0043] The hydroelectric slip ring unit 6 includes a hydroelectric slip ring outer barrel 61, a hydroelectric slip ring inner barrel 62 and a hydroelectric slip ring core shaft 63, which are arranged in sequence from the outside to the inside. The fixture upper cover 411 is connected to the hydroelectric slip ring inner barrel 62 through a transition piece. The hydroelectric slip ring inner barrel 62 is installed between the hydroelectric slip ring outer barrel 61 and the hydroelectric slip ring core shaft 63 for connection. An annular water inlet cavity and an annular water outlet cavity are further provided between the hydroelectric slip ring inner barrel 62 and the hydroelectric slip ring core shaft 63. The bottom end of the hydroelectric slip ring inner barrel 62 is provided with a second water inlet nozzle 64 communicating with the annular water inlet cavity and a second water outlet nozzle 65 communicating with the annular water outlet cavity. The top of the hydroelectric slip ring core shaft 63 is also provided with a first water inlet nozzle 66 communicating with the annular water inlet cavity and a first water outlet nozzle 67 communicating with the annular water outlet cavity.

[0044] The cooling water flows into the water cooling channel from the third water inlet 68 on the transition piece, and then flows out from the third water outlet 69 on the transition piece. The third water inlet 68 is connected to the second water inlet 64 with a water pipe. The second water inlet 64 is connected to the first water inlet 66 through the hydroelectric slip ring core shaft 63. The first water inlet 66 is connected to the water outlet of the external water cooler. The third water outlet 69 is connected to the second water outlet 65 with a water pipe. The second water outlet 65 is connected to the first water outlet 67 through the hydroelectric slip ring core shaft 63. The first water outlet 67 is connected to the return water outlet of the external water cooler, thus realizing a water circulation cooling system loop.

[0045] The transition piece is further provided with a third negative electrode terminal 612 connected to the heating negative electrode 610 and a third positive electrode terminal 613 connected to the heating positive electrode 611. The hydroelectric slip ring inner barrel 62 is further provided with a second negative electrode terminal 614 connected to the third negative electrode terminal 612 and a second positive electrode terminal 615 connected to the third positive electrode terminal 613. The hydroelectric slip ring outer barrel 61 is further provided with a first negative electrode terminal 616 connected to the second negative electrode terminal 614 and a first positive electrode terminal 617 connected to the second positive electrode terminal 615.

[0046] When the hydroelectric slip ring inner barrel 62, the second water inlet 64, the second water outlet 65, the second positive terminal 615, the second negative terminal 614, the third positive terminal 613, the third negative terminal 612, the third water inlet 68, and the third water outlet 69 rotate infinitely with the system, the hydroelectric slip ring outer barrel 61, the hydroelectric slip ring core shaft 63, the first negative terminal 616, the first positive terminal 617, the first water inlet 66, and the first water outlet 67 are all stationary, so as to ensure that the main electrode cables connected to the outside of the system and the inlet and outlet water pipes of the water chiller also remain stationary, so that the external cables and water pipes can remain stationary while the equipment rotates infinitely, avoiding the problem of entanglement.

[0047] The working principle of the present invention is as follows: In actual application, the specimen 7 is installed in the high-temperature load-bearing barrel unit 5. The water slip ring unit 3, the drive and electric slip ring unit 4, the high-temperature load-bearing barrel unit 5, and the water-electric slip ring unit 6 are installed in sequence from bottom to top and integrally mounted on the CT turntable 1. The rotation of the CT turntable 1 drives the system body. During rotation, the specimen 7 is stretched, compressed, or twisted under the drive and electric slip ring unit 4. This achieves 4D animation imaging of the specimen 7 during its continuous rotation of n×360°. This can provide researchers with the most realistic and intuitive internal material damage process in real time, rather than simply outputting a static 3D image as the result, which lacks the effect of animated video recording of the damage process. Because the test needs to be conducted under high temperature conditions of 1500°C, water cooling structures are installed at the top and bottom of the system body to ensure the safe use of the entire equipment at high temperatures. The infinite rotation of n×360° by water and electricity is integrated together, achieving the advantages of light weight and low height, which can be installed in an industrial CT cabin.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
