Description

Technical Field

[0001] This utility model relates to the field of optical instrument technology, and in particular to a high-temperature and high-pressure microscope. Background Technology

[0002] A high-temperature and high-pressure microscope is a precision scientific instrument that can perform in-situ, real-time, and high-resolution microscopic observation of samples under controlled extreme temperature and pressure and preset gas environments. Its core value lies in reproducing real working conditions and capturing microscopic dynamic processes, rather than just looking at static structures. It mainly includes a molding module and a high-temperature and high-pressure autoclave.

[0003] However, in existing high-temperature and high-pressure microscope systems, the high-temperature and high-pressure vessel relies on O-rings to form a seal between the sapphire window and the vessel body. However, under high temperature and pressure, the O-rings are prone to deformation and displacement, leading to seal failure. This results in insufficient pressure range for the entire high-temperature and high-pressure vessel. To improve the sealing performance, additional sealing components are required, which increases the distance between the sapphire observation window and the observation stage, resulting in poor image quality. Therefore, a high-temperature and high-pressure microscope is provided to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a high-temperature and high-pressure microscope to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature, high-pressure microscope, comprising:

[0006] The vessel body;

[0007] A lens is positioned above the vessel body, a camera is mounted on the lens, and a three-axis adjustment component is mounted on the lens to enable the lens to perform three-axis displacement.

[0008] An observation platform is installed at the bottom of the vessel body, and a sapphire observation window is installed on the top of the observation platform. An O-ring for sealing is movably fitted on the outer wall of the sapphire observation window. Positioning retaining rings are provided on the upper and lower sides of the O-ring to restrict the O-ring to a preset position.

[0009] A fixed baffle is installed on the top of the vessel body, and a metal pad is installed on the upper surface of the positioning retaining ring at the top. The top of the metal pad is at the same level as the sapphire observation window, so that the fixed baffle can simultaneously press and secure the metal pad and the sapphire observation window.

[0010] Preferably, the fixed baffle has an observation hole in the middle for exposing the sapphire observation window, and the observation hole is coaxially arranged with the observation base.

[0011] Preferably, a fiber optic backlight is fixedly installed at the bottom of the vessel body, and the fiber optic backlight extends through to the bottom of the observation base.

[0012] Preferably, a heating rod is fixedly installed inside the vessel body, the top end of the heating rod penetrates the fixed baffle, and the fixed baffle is fixedly installed to the vessel body by screws.

[0013] Preferably, the outer surface of the vessel is fixedly fitted with a heat-insulating and anti-scalding outer shell.

[0014] Preferably, a vessel support is fixedly installed at the bottom of the heat-insulating and anti-scalding outer shell, a base plate is fixedly installed at the bottom of the vessel support, and the three-axis adjustment component is installed between the base plate and the lens.

[0015] Preferably, the three-axis adjustment component includes an X-axis moving platform and a Y-axis moving platform stacked on top of the base plate, with a column fixedly installed on the top of the Y-axis moving platform, and a Z-axis moving platform installed between the top of the column and the lens.

[0016] Preferably, the X-axis moving platform and the Y-axis moving platform are arranged perpendicular to each other, and the X-axis moving platform and the Y-axis moving platform have the same structure.

[0018] Preferably, the Z-axis moving platform includes a connecting seat movably sleeved on the column, a mounting part slidably disposed on one side of the connecting seat, the lens being fixedly mounted on the mounting part, a positioning screw threadedly connected to the other side of the connecting seat, a rack fixedly disposed on the mounting part, an adjusting knob rotatably disposed on the connecting seat, a gear meshing with the rack being fixedly disposed at the end of the adjusting knob, and a damping ring disposed between the adjusting knob and the connecting seat.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] This high-temperature and high-pressure microscope employs positioning retaining rings installed on both the upper and lower sides of the O-ring to maintain its position and preset shape. Simultaneously, a metal pad is installed on the upper surface of a set of positioning retaining rings at the top, ensuring that the top of the metal pad is flush with the top of the sapphire observation window. This allows the top fixing plate to simultaneously press and secure both the metal pad and the sapphire observation window during installation, preventing significant deformation and displacement of the O-ring under high temperature and pressure. This increases the pressure resistance of the entire vessel to 150 MPa and the temperature resistance to 200°C, while maintaining the same distance between the sapphire observation window and the observation stage, enabling the microscope system to operate at closer range and improving image quality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figures 1 to 4The high-temperature and high-pressure microscope shown includes a vessel body 11 and a lens 5. The lens 5 is positioned above the vessel body 11, and a camera 7 is mounted on the lens 5. A three-axis adjustment component is also mounted on the lens 5 to allow for three-axis displacement. An observation platform 18 is installed at the bottom inner part of the vessel body 11, and a sapphire observation window 17 is installed on the top of the observation platform 18. An O-ring 13 for sealing is movably fitted onto the outer wall of the sapphire observation window 17. Positioning retaining rings 12 are respectively provided on the upper and lower sides of the O-ring 13 to restrict the O-ring 13 to a preset position. A fixing baffle 15 is installed on the top of the vessel body 11, and a metal pad 14 is installed on the upper surface of the top positioning retaining ring 12. The top of the metal pad 14 is at the same level as the sapphire observation window 17, so that the fixing baffle 15 can simultaneously press and secure the metal pad 14 and the sapphire observation window 17.

[0028] The fixed baffle 15 has an observation hole in the middle for exposing the sapphire observation window 17, and the observation hole is coaxially arranged with the observation base 18.

[0029] A fiber optic backlight 8 is fixedly installed at the bottom of the vessel body 11, and the fiber optic backlight 8 extends through to the bottom of the observation base 18.

[0030] A heating rod 16 is fixedly installed inside the vessel body 11. The top end of the heating rod 16 passes through a fixed baffle 15, which is fixedly installed to the vessel body 11 by screws.

[0031] An insulated and heat-resistant outer shell 10 is fixedly installed on the outer surface of the vessel body 11.

[0032] The bottom of the heat-insulating and heat-proof outer shell 10 is fixedly installed with a vessel support 9, and the bottom of the vessel support 9 is fixedly installed with a base plate 1. The three-axis adjustment component is installed between the base plate 1 and the lens 5.

[0033] The three-axis adjustment component includes an X-axis moving platform 2 and a Y-axis moving platform 3 stacked on top of the base plate 1. A column 4 is fixedly installed on the top of the Y-axis moving platform 3, and a Z-axis moving platform 6 is installed between the top of the column 4 and the lens 5.

[0034] The X-axis moving platform 2 and the Y-axis moving platform 3 are set perpendicular to each other, and the X-axis moving platform 2 and the Y-axis moving platform 3 have the same structure.

[0035] It should be noted that the X-axis moving platform 2 and the Y-axis moving platform 3 are short in length and have a short adjustment range, which is a fine adjustment and will not cause the center of gravity to shift.

[0036] Secondly, the X-axis moving platform 2 and the Y-axis moving platform 3 use dovetail groove guide rails. The dovetail groove guide rails rely on surface contact to achieve sliding guidance, and at the same time have an anti-detachment and limiting effect.

[0037] The X-axis moving platform 2 includes a slide rail 21 and a slider 22 slidably disposed on the slide rail 21. A fixing screw 23 for fixing the slider 22 is threadedly connected to the side of the slide rail 21.

[0038] The Z-axis moving platform 6 includes a connecting seat 61 movably sleeved on the column 4. A mounting part 62 is slidably provided on one side of the connecting seat 61. The lens 5 is fixedly mounted on the mounting part 62. A positioning screw 65 is threadedly connected to the other side of the connecting seat 61. A rack 63 is fixedly provided on the mounting part 62. An adjustment knob 64 is rotatably provided on the connecting seat 61. A gear that meshes with the rack 63 is fixedly installed at the end of the adjustment knob 64. A damping ring 66 is provided between the adjustment knob 64 and the connecting seat 61.

[0039] Working principle: This device modifies the existing vessel body 11 by installing positioning retaining rings 12 on the upper and lower sides of the O-ring 13. The positioning retaining rings 12 maintain the position and preset shape of the O-ring 13. At the same time, a metal pad 14 is installed on the upper surface of a set of positioning retaining rings 12 at the top, so that the top of the metal pad 14 is flush with the top of the sapphire observation window 17. This allows the top fixing baffle 15 to simultaneously press and fix the metal pad 14 and the sapphire observation window 17 during installation, thereby ensuring that the O-ring 13 will not undergo significant deformation or displacement under high temperature and high pressure. This increases the pressure resistance of the entire vessel body 11 to 150 MPa and the temperature resistance to 200℃. At the same time, the distance between the sapphire observation window 17 and the observation base 18 is not increased, allowing the microscope system to use a high-resolution lens 5 with a closer working distance, thus improving image quality.

[0040] Secondly, by setting up a three-axis adjustment component, during use, the X-axis and Y-axis directions on the horizontal plane are adjusted by the mutually perpendicular X-axis moving platform 2 and Y-axis moving platform 3. The Z-axis is adjusted by sliding the connecting seat 61 up and down on the outer surface of the column 4. By rotating the adjustment knob 64, the mounting part 62 moves vertically on the connecting seat 61 to achieve fine Z-axis adjustment, thereby meeting the adjustment and calibration of the lens 5 during use, making it more convenient and faster to use.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
