Description

Technical Field

[0001] This application relates to the field of industrial photography system protection technology, and more specifically, to a photography system protection device for high-temperature and high-pressure environments. Background Technology

[0002] Currently, explosion science is developing rapidly and has been widely applied in the field of defense science and technology research. Meanwhile, modern photographic technology is playing an increasingly important role in the development of explosion science. High-speed photographic observation of the explosion process can capture transient explosion phenomena, allowing for further in-depth research on crack propagation and the physical mechanisms of explosion propagation.

[0003] Existing camera protection systems are insufficient, making cameras vulnerable to damage from air curtains and debris from multiple directions. Furthermore, the protective measures are complex, inconvenient to operate, and require meticulous attention from staff. Summary of the Invention

[0004] The purpose of this application is to provide a protective device for a photography system in a high-temperature and high-pressure environment, so as to solve the technical problems of insufficient protection, complex protection measures, and inconvenient operation of existing photography system protective devices.

[0005] This application provides a protective device for a photography system in a high-temperature and high-pressure environment, comprising: a protective body, including a housing for accommodating a camera and a front door rotatably disposed at the front opening of the housing, the front door being connected to the housing via a rope to close the front opening of the housing; and a rope cutting device disposed on the housing for cutting the rope to open the front opening of the housing.

[0006] In this embodiment, the tension of a rope keeps the front door closed at the front opening of the housing, providing all-around protection for the camera inside the protective body. When it is necessary to take a picture, the rope is cut by a rope-cutting device, freeing the front door from the rope's tension, opening the front opening of the housing, and exposing the camera lens for taking pictures. This camera protection system enhances the camera's protective effect, and taking pictures can be done simply by the operator, making it easy and convenient to use.

[0007] In some embodiments, the rope cutting device includes a slicing blade that contacts the rope and is configured to generate high temperatures in an energized state to melt the rope.

[0008] In this embodiment, the slice can be a high-temperature slice made of a high-temperature resistant material. When energized, it generates high temperature to melt the rope and open the front door.

[0009] In other embodiments, the rope cutting device includes: a fixing component, a piezoelectric component, and an elastic component connected between the fixing component and the piezoelectric component, the fixing component being fixed within the housing, the piezoelectric component penetrating the fixing component, and the end of the piezoelectric component being provided with a slicing element, wherein the piezoelectric component is configured to deform in an energized state to move toward the rope and cut the rope.

[0010] In this embodiment, the rope is cut by the deformation of a piezoelectric component under electricity. By utilizing the sensitive characteristics of piezoelectric materials under electricity, the response speed is faster and the cutting is more rapid.

[0011] In some embodiments, two rope cutting devices are provided, located on opposite sides of the rope.

[0012] In this embodiment, two rope cutting devices are arranged at intervals along the length of the rope and are capable of cutting the rope simultaneously in opposite directions. Because the two rope cutting devices are located at different positions on the rope and cut it simultaneously in opposite directions, the rope tension is greater during the cutting process, resulting in faster cutting efficiency. Furthermore, if one cutting device fails, the other cutting device can still complete the cutting operation normally.

[0013] In some embodiments, the rope is located inside the housing, one end of the rope is fixed to the inner wall of the front door by a locking member, and the other end of the rope is fixed to the top wall of the housing by a fixing pin.

[0014] In this embodiment, the front door is kept closed by the tension of a rope inside the housing, which keeps the front door closed at the front opening of the housing.

[0015] In some embodiments, the sidewall of the housing is provided with a through hole, and the rope cutting device is disposed in the through hole.

[0016] In this embodiment, the through hole can be, for example, a stepped through hole, for installing and fixing components. The piezoelectric component can be fixed to the top wall of the housing by fixing pins. A slice is installed at the front end of the piezoelectric component and a top cap is installed at the rear end. The top cap is used to deform the piezoelectric component towards the direction of the rope when the piezoelectric component is energized. That is, the top cap holds the rear end of the piezoelectric component in place. The deformation of the piezoelectric component causes the slice at its front end to contact the rope, and then the rope is cut, and the front door is opened.

[0017] In some embodiments, a spring is provided between the housing and the front door. Further optionally, a counterweight is provided on the upper side of the front door.

[0018] In this embodiment, the center of gravity of the front door is in the upper part through the combined elastic force of the spring and torsion spring, ensuring that the front door opens quickly when the rope is cut.

[0019] In some embodiments, the housing is a double-layer or multi-layer structure, with thermal insulation material filling the spaces between each layer; and / or, the outer wall of the housing is provided with thermal insulation ceramic.

[0020] In this embodiment, the multi-layered shell enhances impact resistance, and the space between each layer is filled with thermal insulation material to improve thermal insulation performance.

[0021] In some embodiments, the protective device for the photography system further includes a shock-absorbing frame, wherein the protective body is suspended within the shock-absorbing frame.

[0022] In this embodiment, the protective body is connected to the shock-absorbing frame via a suspended flexible connection, thereby mitigating the damage to the protective body caused by the shock wave. Attached Figure Description

[0031] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0032] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Please refer to Figures 1 to 4 , Figure 1 A schematic diagram of the structure of a protective device for a photographing system in a high-temperature and high-pressure environment, provided for an embodiment of this application; Figure 2 This is a schematic diagram of the protective main structure of the protective device provided in the embodiments of this application; Figure 3 This is a cross-sectional schematic diagram of the protective main structure provided in the embodiments of this application; Figure 4 This is a schematic diagram of the protective main body structure provided in an embodiment of this application.

[0034] This application provides a protective device for a photography system in a high-temperature and high-pressure environment. The integrated shell provides better protection for the camera, and the camera can be taken with simple operation by the staff. It also features good heat insulation and simple operation.

[0035] The protective device includes: a protective body 10 and a rope cutting device 30.

[0036] The protective body 10 has a receiving space for accommodating a camera. Specifically, the protective body 10 includes a housing 11 and a front door 12. The housing 11 has a front opening, and the front door 12 is rotatably disposed at the front opening of the housing 11, forming a receiving space together with the housing 11 for accommodating the camera. The front door 12 is used to open or close the front opening of the housing 11 so that the camera lens can take pictures through the front opening of the housing 11. Specifically, the front door 12 is connected to the housing 11 by a rope 40, so that the front door 12 closes the front opening of the housing 11. For example, the rope 40 is located inside the housing 11, one end (front end) of which can be fixed to the inner wall of the front door 12 by fasteners, and the other end (rear end) can be fixed to the top wall of the housing 11 by a pin 41. The front door 12 is kept locked and closed by the tension of the rope 40 inside the housing 11. A sealing ring 15 can be provided between the front door 12 and the housing 11.

[0037] A rope cutting device 30 is disposed in the housing 11 and is used to cut the rope 40 so that the front door 12 opens the front opening of the housing 11, exposing the lens of the camera. The rope cutting device 30 is disposed inside the housing 11 and can be controlled by the control system to cut the rope 40, and the front door 12 opens the front opening of the housing 11 by its own weight.

[0038] In one example, a counterweight 17 can be installed on the upper part of the front door 12 so that the center of gravity of the front door 12 is in the upper part, which makes it easier for the front door 12 to open smoothly when the rope 40 is cut.

[0039] In another example, a torsion spring can be installed at the rotatable connection between the front door 12 and the housing 11. When the front door is closed, the torsion spring is in a compressed state and has a certain elastic potential energy. Specifically, the front door 12 is rotatably connected to the housing 11 via a pivot 13, and a torsion spring is installed at the pivot 13, so that the front door 12 can be opened by its own weight and the elastic force of the torsion spring.

[0040] In another example, a spring is provided between the housing 11 and the front door 12. For example, one or more springs 16 can also be provided on the upper part of the inner side wall of the front door 12, or multiple springs 16 can be provided inside the housing 11. When the front door 12 is closed, the torsion spring is in a compressed state and has a certain elastic potential energy. The front door 12 is opened by the combined action of its own weight, the torsion spring and the spring 16, making the front door 12 open faster and more reliably.

[0041] The protective device for the camera system in this embodiment uses the tension of the rope 40 to keep the front door 12 closed and the front opening of the housing 11 closed. Figure 6 This provides all-around protection for the camera inside the protective body 10. When it is necessary to take pictures, the rope 40 is cut by the rope cutting device 30, so the front door 12 is no longer restrained by the tension of the rope 40, and the front opening of the shell 11 is opened. Figure 7 This camera system exposes the lens of the camera for taking pictures. This protective device enhances camera protection, and the system is easy and convenient for staff to operate.

[0042] In some examples, the aforementioned housing 11 can be a double-layer or multi-layer structure, such as double-layer high-strength super stainless steel, with thermal insulation material, such as aerogel, filling between each layer to enhance impact resistance.

[0043] Alternatively, the outer wall of the housing 11 can be covered with a heat-insulating material, such as ceramic, which serves to insulate against heat, resist high-temperature oxidation and corrosion, and protect the imaging system and key components.

[0044] In some embodiments, the protective device for the photography system may further include a shock-absorbing frame 20, with the protective body 10 suspended within the shock-absorbing frame 20. For example, it may be suspended in the center of the shock-absorbing frame 20. For instance, the shock-absorbing frame 20 may be a steel structure, rectangular in shape, fixed to the ground. The protective body 10 is flexibly connected to the upper part of the shock-absorbing frame 20 via four corner hangers, and to the lower part of the shock-absorbing frame 20 via four corner hangers, thus mitigating the damage of shock waves to the protective body 10. Even under high temperature and high pressure conditions, the front door can be opened normally to complete the shooting task. Pads 14 may be installed at the four upper corners of the protective body 10, with the hangers fixedly installed on the pads 14.

[0045] In some embodiments, the rope cutting device 30 includes a slicing blade that contacts the rope 40 and is configured to generate high temperatures in an energized state to melt the rope 40. The slicing blade may be a high-temperature blade made of a heat-resistant material that generates high temperatures in an energized state to melt the rope 40.

[0046] In other embodiments, reference is made to Figure 4 and Figure 5 The rope cutting device 30 includes a fixing component 31, a piezoelectric component 32, and an elastic component 34 connecting the fixing component 31 and the piezoelectric component 32. The fixing component 31 is fixed inside the housing 11, and the piezoelectric component 32 passes through the fixing component 31. A slice 36 is provided at the end of the piezoelectric component 32. The piezoelectric component 32 is configured to deform and move toward the rope 40 when energized, so that the slice 36 cuts the rope 40.

[0047] For example, a through hole can be provided on the side wall of the housing 11, and the rope cutting device 30 is disposed in the through hole. The through hole can be, for example, a stepped through hole. The aforementioned fixing component 31 can be a flange, which is fixedly installed on the stepped surface of the stepped through hole by bolts. The piezoelectric component 32 is connected to the flange through an elastic component 34. The piezoelectric component 32 can be, for example, a piezoelectric ceramic. The piezoelectric component 32 can be fixed to the top wall of the housing 11 by a fixing pin 33. A slice 36 is installed at the front end of the piezoelectric component 32, and a top cap 35 is installed at the rear end. The top cap 35 is used to deform the piezoelectric component 32 towards the direction of the rope 40 when the piezoelectric component 32 is energized. That is, the top cap 35 holds the rear end of the piezoelectric component 32, and the deformation of the piezoelectric component 32 causes the slice 36 at its front end to contact the rope 40, and then the rope 40 is cut, and the front door 12 is opened.

[0048] In some embodiments, two rope cutting devices 30 are provided, located on opposite sides of the rope 40. For example, the two rope cutting devices 30 are arranged at intervals along the length of the rope 40, and the slices on them can move simultaneously towards each other to cut the rope 40. Because the two rope cutting devices 30 are located at different positions on the rope 40 and simultaneously cut the rope 40 towards each other, the rope 40 experiences greater tension during the cutting process, resulting in faster cutting efficiency. Furthermore, if one cutting device 30 fails, it ensures that the other cutting device 30 can still complete the cutting operation normally.
