Description

Technical Field

[0001] The present application relates to the technical field of physical property measurement under comprehensive extreme conditions, and particularly relates to a rotating device for realizing in-situ rotation of a pressure cell in a small cavity. Background Art

[0002] High-pressure technology can simulate extreme environments, reveal phase transitions, electronic structures, and physical property changes of substances under high pressure, and provide an experimental platform for exploring new quantum materials, superconductors, and strongly correlated substances. In addition, combining high pressure with comprehensive extreme conditions such as strong magnetic fields and extremely low temperatures can further explore the wonderful physical properties of substances under extreme conditions. Since the magnetic field has a directionality, and the physical properties of single-crystal samples vary greatly in different directions, realizing in-situ rotation of the sample in a strong magnetic field environment has become an essential experimental means.

[0003] However, under comprehensive extreme conditions, the existing cavities have a small aperture, limited space for the rotation of the pressure cell, and restricted operating space. Especially in a small-aperture (≤ 30 mm) cavity with a strong magnetic field of up to 35 T, it is very difficult to realize the in-situ rotation operation of the pressure cell, which results in a single magnetic field direction applied to the sample in the pressure cell and the lack of experimental techniques.

[0032] To make the above objects, features, and advantages of the present application more apparent and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0033] In the description of the present application, it should be understood that if these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0034] In addition, if these terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0035] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0038] Refer to Figures 1 to 5 , a rotating device 100 for realizing the in-situ corner rotation of a pressure package in a small cavity shown in an embodiment of this application, which includes a power source 10, a mounting frame 20, a rotating body 30, a transmission assembly 40, and a pressure package 50.

[0039] The power source 10 is disposed outside the mounting frame 20, and a mounting cavity 211 is formed inside the mounting frame 20; the rotating body 30 is rotatably installed in the mounting cavity 211; the transmission assembly 40 is movably disposed in the mounting cavity 211, and one end of the transmission assembly 40 is in transmission connection with the power source 10, and the other end of the transmission assembly 40 is in transmission connection with the rotating body 30; the pressure package 50 is installed on the rotating body 30.

[0040] For example, the installation frame 20 in the present application includes a frame body 21 and a connecting pipe 22, one end of the connecting pipe 22 is connected to the frame body 21, and the other end of the connecting pipe 22 is connected to the power source 10. The connecting pipe 22 connects the frame body 21 and the power source 10 as a whole, and the installation structure is simple, ensuring the overall structural strength and stability of the rotating equipment; in addition, the connecting pipe 22 has a certain length, so that a sufficiently long distance is formed between the frame body 21 and the power source 10, which facilitates the installation of the connecting pipe 22 to avoid interference problems.

[0041] Optionally, the connecting pipe 22 is a pipe made of non-magnetic material, such as a round pipe, a square pipe, etc.

[0042] An installation cavity 211 is formed inside the frame body 21 , and the frame body 21 is used to load the integrated rotating body 30 , the transmission assembly 40 and the pressure bag 50 .

[0043] Specifically, the frame body 21 is cylindrical in shape, and a window extending axially is formed on its circumferential surface. The window makes the installation cavity 211 an open cavity. On the one hand, it can avoid interference between the rotating body 30 and the frame body 21 when rotating. On the other hand, it is also convenient for experimenters to visually grasp the experimental conditions.

[0044] In summary, the implementation of the technical solution of this embodiment will obtain the following beneficial effects: the rotating device 100 of this solution for realizing the in-situ rotation angle of the pressure pack in a small cavity is applied to the occasions of measuring the physical properties of samples under comprehensive extreme conditions. When in use, the sample is loaded into the pressure pack 50, and then the pressure pack 50 is installed on the rotating body 30, and then the driving force is output to the transmission component 40 by controlling the power source 10, and the rotating component can drive the rotating body 30 to rotate arbitrarily in the installation cavity 211, so as to drive the sample to rotate and achieve the effect of adjusting the angle of the sample; in this way, the physical properties under the conditions of magnetic fields of different directions applied to the sample can be tested, avoiding the lack of experimental technology and ensuring the experimental effect.

[0045] Please continue reading Figure 2 , Figure 4 and Figure 5 In an optional embodiment, the rotating body 30 includes a rotor 31 and a shaft member 32, one end of the shaft member 32 is rotatably disposed on the side wall of the installation cavity 211, and the other end of the shaft member 32 is connected to the rotor 31. Therefore, the shaft member 32 is rotatably mounted on the side wall of the installation cavity 211, and the shaft member 32 can rotate to provide the required rotational freedom of the rotor 31.

[0046] The rotor 31 is drivingly connected to the other end of the transmission assembly 40, and the rotor 31 is formed with a receiving cavity, and the pressure package 50 is installed in the receiving cavity. The receiving cavity can receive and install the pressure package 50, so that the pressure package 50 is assembled and fixed with the rotor 31, so that the rotation of the rotor 31 can synchronously drive the pressure package 50 to rotate, achieving the purpose of flexibly adjusting the angle of the sample in the pressure package 50.

[0047] Please continue to refer to Figure 2 , Figure 4 and Figure 5 , further, in order to ensure that the pressure package 50 is firmly installed in the rotor 31 and prevent loosening or even falling during rotation, the rotating body 30 further includes a limiting member 33. The rotor 31 is provided with an installation through hole communicating with the receiving cavity. The limiting member 33 is inserted into the installation through hole, and one end of the limiting member 33 extending into the receiving cavity abuts against the outer wall of the pressure package 50 for positioning.

[0048] For example, the installation through hole is set as a threaded hole, the limiting member 33 is a screw, the screw is screwed into the threaded hole, and the end of the screw abuts against the pressure package 50 to realize pressing and fixing the pressure package 50.

[0049] Preferably, the rotor 31 is a toroidal body, and there are multiple threaded holes (for example, four are provided in this application). The multiple threaded holes are arranged at intervals along the circumferential direction of the rotor 31. Each threaded hole is screwed with a screw, and the multiple screws simultaneously abut against the pressure package 50 to further improve the installation stability of the pressure package 50.

[0050] In addition, on the basis of any of the above embodiments, the power source 10 is set as a telescopic driver for outputting telescopic linear power. For example, the telescopic driver can be, but is not limited to, any one of a high-precision stepper, an electric push rod, a linear motor, a precision cylinder, etc., and can be flexibly selected according to actual needs.

[0051] Please continue to refer to Figure 2 , Figure 4 and Figure 5 , the transmission assembly 40 includes a first pulling member 41 and a positioning wheel 42. The outer wall of the rotor 31 is provided with a first connection hole 311. The positioning wheel 42 is rotatably arranged on the side wall of the installation cavity 211. The first pulling member 41 is movably wound around the outside of the positioning wheel 42, and one end of the first pulling member 41 is connected to the telescopic shaft of the telescopic driver, and the other end of the first pulling member 41 is arranged in the first connection hole 311.

[0052] The positioning wheel 42 is used for installing and positioning the first pulling member 41, so that the first pulling member 41 is in a taut state, so as to better transmit the power output by the telescopic driver to the rotor 31; in addition, the positioning wheel 42 also plays a guiding and limiting role for the first pulling member 41 during movement.

[0053] During use, the telescopic driver pulls the first pulling member 41, and the first pulling member 41 synchronously applies a pulling force to the rotor 31, thereby driving the rotor 31 to rotate around the rotating shaft member 32 as the rotation center, and further adjusting the angle of the sample in the pressure package 50.

[0054] It is easy to understand that by controlling the telescopic force of the telescopic driver, the moving stroke of the first pulling member 41 can be controlled, and then the rotation angles of the rotor 31, the pressure package 50 and the sample can be controlled.

[0055] On the basis of the above embodiment, at least two positioning wheels 42 are provided, and the at least two positioning wheels 42 are arranged at intervals, and the first pulling member 41 is successively wound around the outside of the at least two positioning wheels 42. The use of at least two positioning wheels 42 to be wound and installed with the first pulling member 41 simultaneously helps to improve the installation effect and reliability of the first pulling member 41. Even if the first pulling member 41 accidentally falls off one of the positioning wheels 42, the remaining positioning wheels 42 can still ensure the normal operation of the first pulling member 41.

[0056] It is easy to understand that the positioning wheel 42 acts as a fixed pulley, and a wheel groove is formed on the circumferential surface of the positioning wheel 42. The first pulling member 41 uses a thin wire, and the thin wire is installed in the wheel groove, and the groove side wall plays a role in limiting the thin wire, so as to better prevent the thin wire from detaching from the positioning wheel 42.

[0057] Please continue to refer to Figure 2 , Figure 4 and Figure 5 , in addition, on the basis of the above embodiment, the rotating device 100 for realizing the in-situ rotation angle of the pressure package in the small cavity further includes a second pulling member 60 and an elastic member 70. A second connection hole 312 is further provided on the outer wall of the rotor 31. One end of the second pulling member 60 is arranged in the second connection hole 312, one end of the second pulling member 60 is connected to one end of the elastic member 70, and the other end of the elastic member 70 is arranged on the mounting frame 20.

[0058] During use, the rotor 31 that is pulled and rotated synchronously forms a pulling effect on the second pulling member 60, so that the second pulling member 60 will pull the elastic member 70 to generate tensile deformation and store energy; when the experiment is over, after the telescopic driver releases the first pulling member 41, by means of the elastic member 70 applying an elastic pulling force to the second pulling member 60, the rotor 31 and the pressure package 50 can be pulled to rotate and reset automatically, improving the automation degree of the device and facilitating the next experiment.

[0059] Optionally, the second pulling member 60 uses a thin wire. The elastic member 70 uses a non-magnetic spring.

[0060] Please continue to refer to Figure 2, Further, the installation frame 20 is provided with a first guiding hole 212 and a second guiding hole 213. The first pulling member 41 is movably inserted into the first guiding hole 212, and the second pulling member 60 is movably inserted into the second guiding hole 213. During use, the first pulling member 41 and the second pulling member 60 slide in the first guiding hole 212 and the second guiding hole 213 respectively, and the hole walls play a role in guiding and limiting the first pulling member 41 and the second pulling member 60, improving the moving stability of the first pulling member 41 and the second pulling member 60.

[0061] It should be noted that, in order to reduce the frictional resistance and wear during the sliding of the first pulling member 41 and the second pulling member 60, the aperture of the first guiding hole 212 should be larger than the wire diameter of the first pulling member 41, and the aperture of the second guiding hole 213 should be larger than the wire diameter of the second pulling member 60.

[0062] More specifically, the first pulling member 41 and the second pulling member 60 are any one of components such as ropes, wires, chains, belts, etc. made of non-magnetic materials, and can be selected according to actual needs.

[0063] It should be noted that, compared with the prior art in which a driving unit needs to be installed outside the radial direction of the rotating body to drive the rotating body to rotate, the present application uses a wire-pulling method to drive the rotating body to drive the pressure package to rotate, which can eliminate the setting of the driving unit, thereby reducing the space occupation of the installation cavity.

[0064] Based on any of the above embodiments, the rotating device 100 for realizing the in-situ rotation angle of the pressure package in the small cavity further includes a temperature measuring device 80. The temperature measuring device 80 is installed on the side wall of the installation cavity 211 and is disposed opposite to the pressure package 50. The temperature measuring device 80 is used to measure the real-time temperature of the sample in the pressure package 50, so as to realize the physical properties of the sample under extreme temperature conditions such as extremely low temperature.

[0065] For example, the temperature measuring device 80 can be any one of a temperature sensor, a Cernox thermometer, etc., and can be flexibly selected according to actual needs.

[0066] Further, the rotating device 100 for realizing the in-situ rotation angle of the pressure package in the small cavity further includes an angle calibration device 90. The angle calibration device 90 is installed on the upper surface of the pressure package 50. The angle calibration device 90 is used to measure the angle of the sample in the pressure package 50 in real time, so as to test the variation law of the physical properties of the sample when the magnetic field acts on samples at different angles.

[0067] For example, the angle calibration device 90 includes an angle sensor.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0069] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
