Description

Technical Field

[0001] This utility model relates to the field of camera protection technology, specifically an explosion-proof camera cover. Background Technology

[0002] Explosion-proof cameras belong to the category of explosion-proof monitoring products. They are a cross-product of the explosion-proof and monitoring industries. Because conventional camera products cannot be used in highly dangerous, flammable, or explosive environments, they are mainly used in chemical or gas station fields. Only products with explosion-proof functions and relevant certificates issued by national authoritative institutions can be called explosion-proof cameras. Polishing is the process of reprocessing the surface of a workpiece using polishing tools and abrasive particles or other polishing media. Shoes need to be polished during the production process to improve the flatness and smoothness of the surface. If the soles of casual shoes are not polished, they will have an uneven feel.

[0003] A search revealed that patent application number 202322858586.2 discloses an explosion-proof camera cover, belonging to the field of explosion-proof cameras. The explosion-proof camera cover includes a placement cylinder and a protective cylinder sleeved around the placement cylinder. A buffer spring is fixedly connected to the inner wall of the protective cylinder, with the contact end of the buffer spring abutting against the outer wall of the placement cylinder. A buffer pad is provided between the placement cylinder and the protective cylinder, and the buffer pad cooperates with the placement cylinder and the protective cylinder. This invention can reduce the impact of shock on the explosion-proof camera and improve the stability of the internal components of the camera during use.

[0004] The aforementioned application documents achieve protection for the inner cameras of each group through the settings of each group. However, the overall explosion-proof effect of the buffer protection method is limited. Once the camera at the top explodes due to the explosion of the inner components, the entire camera will be blown into multiple fragments. Combined with its high position, this will increase the impact of the explosion.

[0005] Therefore, we propose an explosion-proof camera housing. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an explosion-proof camera cover, which solves the problem that existing devices are unable to provide efficient explosion-proof protection for cameras according to requirements.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an explosion-proof camera cover, comprising upper and lower covers that surround and protect the camera and its top and bottom sides;

[0008] The protective cover is a slanted U-shaped frame. The entire protective cover is made of pure aluminum. The inner side of the protective cover has an inner cavity with a tail opening. The inner cavity of the protective cover is filled with inert gas, and the front end of the protective cover has a cover edge located diagonally above the camera.

[0009] As a preferred embodiment of this utility model, a side frame is provided at the edge of the protective cover, and the side frame is provided with screw holes distributed at intervals, and the upper and lower sets of screw holes are assembled together by fastening bolts.

[0010] The upper and lower protective covers are in contact with each other through the side frames. The top surface of the side frames is a horizontal surface, and the upper and lower sets of side frames are pressed together by a sealing strip.

[0011] As a preferred embodiment of this utility model, the inner side of the side frame has an internal groove, and the internal groove and the inner cavity are separated by a thin layer of aluminum.

[0012] The built-in slot facilitates the mounting of the support frame. Additionally, the thin aluminum layer allows inert gas to come into contact with the explosion site on the camera when it explodes, diluting the concentration of flammable gases in the environment below the lower explosive limit. Since most flammable materials require a certain concentration range to burn, the addition of inert gas reduces the concentration of flammable materials, preventing the formation of an explosive mixture and fundamentally reducing the impact of the explosion, thus achieving highly efficient explosion protection.

[0013] As a preferred embodiment of this utility model, the tail end of the protective cover is welded with a seal, and the seal is filled on the tail end of the inner cavity.

[0014] The welding seal can encapsulate the inner cavity from the tail end, and the welding seal is provided with an inflation hole for filling the inner cavity with inert gas.

[0015] As a preferred embodiment of this utility model, the inner side of the protective cover is provided with a support frame located between it and the camera. The support frame is a mica frame and is a slanted U-shaped frame with the same shape as the camera.

[0016] The design of the support frame material utilizes its high thermal conductivity to dissipate heat, ensuring the normal operation of the camera and reducing the probability of camera explosion. Its shape also ensures the integration effect during assembly, increasing practicality.

[0017] As a preferred embodiment of this utility model, the inner side of the receiving frame is provided with a through air hole, and the receiving frame and the outer wall of the camera are pressed together by an elastic cotton pad.

[0018] The central ventilation hole in the support frame increases the contact area between it and the passing airflow, further enhancing its heat dissipation effect.

[0019] This utility model provides an explosion-proof camera housing. It has the following beneficial effects:

[0020] This explosion-proof camera housing, through the design of upper and lower covers, allows for press-fitting and integration of the camera inside from the top and bottom sides. A support frame provides efficient heat dissipation, reducing the probability of explosion. A thin aluminum layer between the internal slot and the inner cavity allows the explosive gas flow to break through this layer in the event of an explosion, bringing the gas into contact with an inert gas. This inert gas dilutes the concentration of surrounding flammable gases, keeping it below the lower explosive limit. Since most flammable materials require a certain concentration range to burn, the addition of inert gas reduces the concentration of flammable materials, preventing the formation of an explosive mixture and fundamentally reducing the impact of the explosion. This achieves highly efficient explosion protection, solving the problem of existing devices being unable to provide efficient explosion protection for cameras according to specific needs.

[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] Please see Figure 1-4 This utility model provides a technical solution: an explosion-proof camera cover, including a camera 1 and two sets of upper and lower covers 2 that surround and protect the camera 1 on its top and bottom sides; the cover 2 is a slanted U-shaped frame, the cover 2 is made of pure aluminum, the inner side of the cover 2 has an inner cavity 24 with a tail opening, the inner cavity 24 of the cover 2 is filled with inert gas, and the front end of the cover 2 is provided with a cover edge 5 located diagonally above the camera 1;

[0028] The explosion-proof camera housing, through the upper and lower housings 2 of the camera 1, can press and integrate the camera 1 inside from the top and bottom sides, and the receiving frame 4 provides efficient heat dissipation, reducing the probability of explosion. The thin aluminum layer between the built-in groove 23 and the inner cavity 24, when an explosion occurs, the explosive gas flow breaks through the thin aluminum layer, allowing the explosive gas flow to come into contact with inert gas. The inert gas dilutes the concentration of the surrounding combustible gas, making it below the lower explosive limit. Most combustibles require a certain concentration range to burn. The addition of inert gas reduces the concentration of combustibles, preventing the formation of an explosive mixture, fundamentally reducing the impact of the explosion and achieving a highly efficient explosion-proof effect. This solves the problem that existing devices cannot provide efficient explosion-proof protection for the camera 1 according to requirements.

[0029] A side frame 21 is provided at the edge of the protective cover 2. The side frame 21 has screw holes 22 distributed at intervals. The upper and lower sets of screw holes 22 are assembled with fastening bolts. The upper and lower protective covers 2 are in contact with each other through the side frame 21. The top surface of the side frame 21 is a horizontal surface. The upper and lower sets of side frames 21 are pressed together by a sealing strip gasket.

[0030] The inner side of the side frame 21 has an internal groove 23, and there is a thin layer of aluminum between the internal groove 23 and the inner cavity 24. The internal groove 23 facilitates the clamping of the support frame 4. At the same time, the thin aluminum layer allows the aluminum to break and inert gas to come into contact with the explosion site on the camera 1 when the camera 1 explodes. This dilutes the concentration of flammable gas in the environment, making it lower than the lower explosive limit. Most flammable materials require a certain concentration range to burn. The addition of inert gas will reduce the concentration of flammable materials, preventing them from forming an explosive mixture, thus fundamentally reducing the impact of the explosion and achieving a highly efficient explosion-proof effect.

[0031] The tail end of the protective cover 2 is welded with a seal 3, and the seal 3 is filled on the tail end of the inner cavity 24; wherein, the seal 3 is provided to encapsulate the inner cavity 24 from the tail end, and the seal 3 is provided with an inflation hole for filling the inner side of the inner cavity 24 with inert gas.

[0032] The inner side of the protective cover 2 is provided with a support frame 4 located between it and the camera 1. The support frame 4 is a mica frame and is a slanted U-shaped frame with the same shape as the camera 1. The material of the support frame 4 can use its efficient thermal conductivity to dissipate heat, ensure the normal operation of the camera 1, and reduce the probability of the camera 1 exploding. The shape of the support frame 4 can ensure the integration effect during assembly and increase its practicality.

[0033] The inner side of the receiving frame 4 is provided with a through-hole, and the receiving frame 4 and the outer wall of the camera 1 are pressed together by an elastic cotton pad; the through-hole in the receiving frame 4 can increase the contact area between it and the passing airflow, and further increase its heat dissipation effect.

[0034] The working principle and usage process of this utility model are as follows: When the device needs to work, the protective cover 2 is pressed onto the upper and lower parts of the camera 1 from both the top and bottom sides to ensure the integration and protection effect. The support frame 4 is set to contact the camera 1 from the periphery and ensure heat dissipation, fundamentally reducing the real-time temperature of the electronic components inside the camera 1 during operation, and simultaneously reducing the probability of explosion. In the event of an explosion, the camera 1 will emit a large amount of explosive gas to the periphery, which will break through the support frame 4 and the thin aluminum layer between the built-in groove 23 and the inner cavity 24, causing the inert gas in the inner cavity 24 to mix with the explosive gas. The inert gas is used to dilute the concentration of the explosive gas around it, making it lower than the lower explosive limit. Most combustibles require a certain concentration range to burn. The addition of inert gas will reduce the concentration of combustibles, preventing them from forming an explosive mixture, fundamentally reducing the impact of the explosion, achieving a highly efficient explosion-proof effect, and solving the problem that existing devices cannot provide efficient explosion-proof protection for the camera 1 according to requirements.
