Description

Technical Field

[0001] The utility model belongs to the technical field of camera protection, and relates to a protective device for an industrial camera which is dustproof and high-temperature proof and convenient for maintenance and debugging. Background Art

[0002] The working environment of metallurgy, petroleum, chemical industry and other industries is mostly harsh environment with high temperature, high dust and high water mist. With the rapid improvement of the intelligence level of these industries, optical equipment such as industrial cameras and spectrometers have been more and more widely used. However, due to working in a high temperature environment with large dust or water mist, the use of these optical equipment is poor. Therefore, the protection of industrial cameras becomes particularly important. The protective device can effectively prevent the equipment from direct contact with dust or water mist, reduce the working temperature of the industrial camera, thereby protecting the equipment and increasing the service life of the equipment.

[0003] The previous protection method was frequent manual cleaning, which not only reduced the utilization rate of industrial cameras, but also was difficult to implement continuously. The existing technology for protecting most industrial cameras is to directly purge and cool the industrial cameras with cooling gas. When the cooling gas contains water vapor or dust, it will cause poor image quality or damage to the camera; or every time the camera is adjusted to the focal length, angle and other parameters, the protective device needs to be removed, which takes at least several hours, greatly reducing work efficiency. Therefore, a camera protective device is needed to prevent water mist and dust from accumulating on the camera lens. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the utility model provides an industrial camera protection device that is easy to maintain, so as to ensure that dust, water mist and other invading objects cannot enter the lens, and the device is easy to disassemble and maintain.

The first outer cavity is connected to the internal thread on the end side of the second outer cavity through the external thread on its end side to form a protective shell of the camera protection device; the industrial camera is installed toward the high-transmittance glass lens and fixed to the industrial camera bracket by bolt connection. The industrial camera bracket is processed with a waist-shaped hole to facilitate the adjustment of the camera installation position; the industrial camera bracket is designed to be L-shaped, and the base is connected and fixed to the end cover by bolts; two circles of bolt holes are designed on the end cover, the outer circle of screw holes is used to connect and fix to the end face of the first outer cavity, and the inner circle of screw holes is used to connect and fix to the end face of the first inner cavity. At the same time, a step is processed on the side where the first inner cavity is connected to the end cover, and its outer diameter is the same as that of the first inner cavity. The inner diameter of an outer cavity is consistent in size; the inner cavity is a hollow tubular structure; the inner cavity is divided into a two-section design of a first inner cavity and a second inner cavity, and a sealing ring is installed at the connection between the first inner cavity and the second inner cavity; the second inner cavity is processed with a serrated step on the side close to the high-transmittance glass lens, and the outer diameter of the serrated step is consistent with the inner diameter of the second outer cavity; the serrated step of the second inner cavity is connected to the airway plate by bolts, and a high-transmittance glass lens is placed in the middle, and the serrated step and the airway form a gas channel; the airway plate is designed with two circles of bolt holes like the end cover, the outer circle of screw holes is used to connect and fix with the end face of the second outer cavity, and the inner circle of screw holes is used to connect and fix with the end face of the second inner cavity; the outer cavity and the inner cavity are connected by threads to form a whole, the first outer cavity and the second outer cavity constitute the outer shell of the cavity, and the first inner cavity and the second inner cavity constitute the inner liner of the cavity.

[0007] Furthermore, two through holes are designed on the end cover for installing a network cable quick connector and an industrial camera power connector.

[0008] Beneficial effects of the invention: The utility model constructs two cavities, one cavity is used for gas cooling and purging and dust removal, and the other cavity is used to install industrial cameras to isolate external pollution. This ensures that dust, water mist and other invaders cannot enter the lens. The dual-cavity design greatly improves the high-temperature resistance of industrial cameras, and the positive-pressure air curtain design prevents dust from adhering to the lens and affecting the imaging effect. At the same time, the cavity adopts a threaded design, which is different from traditional protective devices. The maintenance and debugging of industrial cameras can be completed without disassembling the protective device, which greatly saves the maintenance and debugging time of technicians and saves human resources.

The first outer cavity 7 is connected to the inner thread 9 of the second outer cavity 11 through the outer thread 8 on its end side to form a protective shell of the camera protection device. This protective shell is connected by threading, and the function is to quickly disassemble the protective cover device to save debugging time. The industrial camera 3 is installed in the direction of the high-transmittance glass lens 15 and is fixed to the industrial camera bracket 2 by bolt connection. The industrial camera bracket 2 is processed with a waist-shaped hole to facilitate the camera to adjust the installation position. The industrial camera bracket 2 is designed to be "L"-shaped, and the base is connected and fixed to the end cover 1 by bolts. Two through holes are designed on the end cover 1 for installing the network cable quick connector and the industrial camera 3 power connector to achieve the quick plug function. In addition, two circles of bolt holes are designed on the end cover 1. The outer circle of screw holes is used to connect and fix with the end face of the first outer cavity (7), and the inner circle of screw holes is used to connect and fix with the end face of the first inner cavity 4. At the same time, a step is processed on the side where the first inner cavity 4 is connected to the end cover 1, and its outer diameter is consistent with the inner diameter of the first outer cavity 7. Through this connection method, the first outer cavity 7 and the first inner cavity 4 form a stable cavity A part, which is convenient for the circulation of cooling gas and realizes cooling in the first layer of the cavity. The inner cavity is a hollow tubular structure, so that the industrial camera 3 can be installed smoothly. The inner cavity is divided into a two-stage design of the first inner cavity 4 and the second inner cavity 13. A sealing ring 10 is installed at the connection between the first inner cavity 4 and the second inner cavity 13 to form a second layer of the cavity.
