Description

Technical Field

[0001] The utility model relates to the technical field of image acquisition devices, and particularly relates to a high-temperature endoscope for the vertical brick gas channels of a coke oven. Background Art

[0002] In the coking industry, as the core equipment, the stable operation of the coke oven is directly related to the efficiency and safety of the entire production line. As a key structure of the internal heating system of the coke oven, the state monitoring and sealing maintenance of the vertical brick gas channels of the coke oven are crucial for ensuring the long-term efficient operation of the coke oven and meeting environmental protection standards. However, due to the high temperature, narrow space and harmful gas filling in the vertical brick gas channels of the coke oven, the traditional manual detection method cannot directly observe the state of the vertical brick gas channels, and there are also great potential safety hazards. Therefore, it is particularly important to develop a device that can perform efficient and safe detection in a small space.

[0003] At present, there are already various industrial endoscopes used in high-temperature environments on the market, and these devices have solved the detection problems in high-temperature environments to a certain extent. However, for the specific application scenario of the vertical brick gas channels of the coke oven, there are still many deficiencies in the existing technology. For example, due to the large volume of some endoscope devices and the narrow space of the vertical brick gas channels of the coke oven, they cannot be inserted into small spaces such as the vertical brick gas channels of the coke oven for detection; at the same time, the damage of high-temperature environment to the internal components of the device also limits its service life and stability. Summary of the Utility Model

[0004] In order to solve the above problems, the embodiment of the utility model provides a high-temperature endoscope for the vertical brick gas channels of a coke oven, which can operate in high-temperature and narrow environments.

[0005] The embodiment of the utility model specifically adopts the following technical solutions to achieve the above purpose: a high-temperature endoscope for the vertical brick gas channels of a coke oven, including a housing, one end of the housing is provided with a mounting seat, a data transmission pipe connected to the mounting seat is arranged in the housing, a cooling chamber is arranged between the data transmission pipe and the inner side wall of the housing, and a cold source connecting pipe is arranged at the end of the cooling chamber.

[0006] As a further improvement of the above technical solution:

[0007] The mounting seat includes a substrate, an image acquisition module is arranged on the substrate, and a sleeve connected to the housing is arranged inside the substrate.

[0008] The image acquisition module includes a high-temperature resistant camera, and lighting lamps are arranged around the high-temperature resistant camera.

[0009] A limiting platform corresponding to the position of the data transmission pipe is arranged on the inner side wall of the substrate, and ventilation holes are arranged on the substrate outside the limiting platform.

[0010] The number of the lighting lamps is multiple and they are evenly distributed along the circumferential direction of the high-temperature resistant camera, and the limiting platform is located outside the lighting lamps.

[0011] A sealing end cover is arranged at the end of the housing, a penetration hole is arranged in the middle of the sealing end cover, and a plugging pipeline for installing a cold source connecting pipe is arranged on one side of the penetration hole.

[0012] The beneficial effects of the embodiment of the present utility model are as follows: 1. The high-temperature endoscope for the vertical brick gas duct of the coke oven includes a housing. An installation seat is arranged at one end of the housing. A data transmission pipe connected to the installation seat is arranged inside the housing. A data transmission line and a power cable are arranged inside the data transmission pipe. A cooling chamber is arranged between the data transmission pipe and the inner side wall of the housing. A cold source connecting pipe is arranged at the end of the cooling chamber. The cold source connecting pipe can provide cold quantity to the housing during operation, extend the operation stability of the equipment in a high-temperature environment. Compared with the existing high-temperature endoscope, the heat erosion received by the equipment during operation can be reduced through the cold source connecting pipe, and the working life of the equipment can be extended.

[0013] 2. The design of the cooling chamber can avoid the direct contact between the cables inside the housing and the side wall of the housing. While isolating, it can also facilitate the passage of cold air to cool the inside of the housing, further improving the stability of the internal communication and power supply lines.
