However, when the motor arranged in the vacuum cavity is damaged, the entire vacuum equipment needs to be shut down for maintenance, which affects the normal operation of the entire equipment. Moreover, the heat generated by the motor during operation is difficult to dissipate in the vacuum environment, which may easily cause the motor to burn out. In addition, the internal environment of the vacuum equipment is often harsh, such as high temperature, high dust and radiation.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0028] Referring to Figure 1 The embodiment discloses a vacuum observation device for high-temperature, high-dust and radiation-proof environment, which comprises a window body, a camera 8, a driver, a flashing board 1 and a dynamic seal 6.

[0029] The window body is connected to a vacuum chamber, the camera 8 is arranged outside the window body, the flashing board 1 is arranged inside the window body, the first through hole is arranged on the window body, and the driver is arranged outside the window body.

[0030] The camera hole is arranged on the flashing board 1.

[0031] The driver is connected to the flashing board 1 through the first through hole on the window body, and the dynamic seal 6 is arranged at the first through hole on the window body.

[0032] The existing vacuum observation window sets the flashing board and the driver entirely in the vacuum observation window. Although the vacuum observation window has simple structure and does not need to consider the sealing problem, the driver has high working frequency and long working time, and it is difficult for the driver to dissipate heat in the vacuum environment. Moreover, some vacuum chambers are high-temperature, high-dust and radiation environments, so the driver is easily damaged in the normal use process. When the driver is damaged and needs to be repaired or replaced, the whole vacuum equipment needs to be stopped, which causes large loss of downtime and is more troublesome for repair or replacement.

[0033] The flash frequency plate 1 is arranged in the window body, and the driver is arranged outside the window body. The flash frequency plate 1 is a circular stainless steel plate. Several bending structures are arranged on the outer side of the diameter of the stainless steel plate, so as to increase the strength. A long hole with a width of 0.5 mm is engraved on the stainless steel plate as a camera hole. The camera is matched with the rotating frequency of the driver. When the flash frequency plate 1 rotates at a certain speed, the camera 8 can observe the working condition behind the camera hole at a fixed frequency. Meanwhile, the flash frequency plate can shield a large amount of dust and heat in the vacuum chamber. The industrial motor of 380 V can be selected as the driver outside the window body, and the driver will not be burnt by fire. Meanwhile, the heat generated by the driver can be quickly dissipated in the air. The heat generated by the vacuum melting will not affect the normal work of the driver. Meanwhile, the structure is particularly suitable for the condition with dust. The dust generated in the furnace will not affect the normal work of the driver.

[0034] In the embodiment, the driver is a servo motor 7, and the dynamic sealing element 6 is a magnetic fluid sealing element. The servo motor 7 can accurately control the rotating speed of the flash frequency plate 1. Since the servo motor 7 needs to be operated at high speed for a long time, if the dynamic sealing element adopts a conventional sealing structure, the continuous use time is usually short. In the embodiment, the magnetic fluid sealing is adopted. The magnetic fluid sealing is in the form of magnetic powder sealing. There is no friction between the sealing element and the output shaft of the servo motor 7. The high-speed and long-time work of the motor can be ensured, and the magnetic fluid sealing element will not be damaged. Therefore, the vacuum in the window body can be maintained, and the servo motor 7 can be stably worked for a long time.

[0035] Further, the embodiment further comprises a dustproof glass 2.

[0036] The dustproof glass 2 is arranged in the window body and located at the back side of the flash frequency plate 1. The dustproof glass can isolate a large amount of dust in the vacuum chamber, so as to avoid that the dust shields the camera view of the camera 8.

[0037] Further, the embodiment further comprises a knob 4 and first and second gears 3 and 5 which are engaged with each other.

[0038] The first and second gears 3 and 5 are located in the window body. The dustproof glass 2 in the embodiment is circular, and the center of the circle is connected with the second gear 5. The second through hole is also arranged on the window body. The knob 4 is connected with the first gear 3 through the second through hole. When the dust adhered on the dustproof glass 2 affects the camera view of the camera 8, the knob 4 can be rotated outside the window body. The knob 4 drives the first gear 3 to rotate, the first gear drives the second gear 5 and the dustproof glass 2 connected with the second gear 5 to rotate, so as to adjust the part with adhered dust to the outside of the camera view of the camera 8. Therefore, the device can also work normally for a long time in the high dust environment.

[0039] Further, the embodiment also comprises a heat insulation glass 10 arranged in the window body, which is arranged close to the camera 8 and used to insulate the heat generated in the vacuum chamber.

[0040] Further, the heat insulation glass 10 is arranged with a collection net on the side close to the vacuum chamber. Even if the heat insulation glass 10 is broken, the glass fragments will be blocked by the collection net and will not fall into the vacuum chamber.

[0041] Further, the embodiment also comprises a radiation-proof glass 9 arranged on the side of the window body close to the camera 8. Specifically, the radiation-proof glass 9 of the embodiment is a lead-containing glass.

[0042] Further, the window body of the embodiment is also arranged with a cooling pipeline 12. The cooling pipeline 12 can use cooling water as the cooling medium to exchange the heat absorbed by the window body structure, so as to reduce the temperature of the window body and make it work in a suitable working condition.

[0043] Further, the window body of the embodiment is also connected with a gas filling port 13, through which argon gas or other gas can be filled into the window body, so as to isolate dust and avoid the dust from adhering to the surface of the internal components of the window body.

[0044] The window body structure of the embodiment can be an integrally formed mechanism or a combined structure of components, and a sealing ring 11 can be arranged at the connecting position of the window body structure and between the components and the window body structure to seal.

[0045] It should be noted that, in the present text, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms “include”, “contain” or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0046] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
