Description

Technical Field

[0001] The present invention relates to an endoscope, and more particularly to a high-temperature industrial endoscope with a distributed optical aperture system. Background Art

[0002] Since the high-temperature furnace endoscope needs to work in the high-temperature environment inside the furnace, and the endoscope needs to have a certain length to keep the photographic equipment away from the high-temperature furnace, and the diameter of the endoscope should not be too large, the design of the high-temperature furnace endoscope needs to consider many material and shape size factors.

[0003] Due to the extremely high temperature inside the furnace, even with a water-cooling device, the endoscope objective lens cannot directly work inside the furnace. And the photographic equipment is more sensitive to the ambient temperature. Being too close to the furnace will cause the photographic equipment to malfunction. In addition, too large an opening is not conducive to the temperature control inside the furnace, and an endoscope that is too thick cannot pass through the furnace opening to work properly.

[0004] And in order to ensure the integrity of imaging, multiple sets of cameras are installed on the existing endoscopes. However, the imaging of multiple sets of cameras is often separated, and the operator needs to splice and combine them in the mind during observation, which poses a certain obstacle to observation.

[0005] Therefore, in order to solve the above problems, it is particularly important to design a high-temperature industrial endoscope with a distributed optical aperture system. Summary of the Invention

[0006] In order to solve the above problems, the present invention designs a high-temperature industrial endoscope with a distributed optical aperture system. At the end of the explosion-proof housing of the high-temperature endoscope, a multi-optical lens module composed of five cameras is provided. Through this module, the environment inside the high-temperature furnace can be photographed in all directions, and thus through the processing of the distributed optical aperture system, panoramic display can be directly carried out, which plays a role in increasing the practical performance.

[0007] To solve the above technical problems, the present invention provides a high-temperature industrial endoscope with a distributed optical aperture system, including an explosion-proof housing of the high-temperature endoscope, characterized in that: a thermal imaging device is installed at one end of the explosion-proof housing of the high-temperature endoscope, the explosion-proof housing of the high-temperature endoscope is connected to the XY-axis drive mechanism through a support seat, a multi-optical lens module of the distributed optical aperture system is installed at the other end of the explosion-proof housing of the high-temperature endoscope, one end of the XY-axis drive mechanism is fixedly connected to a water-cooled substrate, the water-cooled substrate is installed on the side wall of the high-temperature furnace and a through hole is opened at a position directly opposite to the endoscope inlet and outlet on it, and the multi-optical lens module on the explosion-proof housing of the high-temperature endoscope penetrates through the through hole under the action of the XY-axis drive mechanism and extends into the high-temperature furnace along the endoscope inlet and outlet.

[0008] Further: The multi-optical lens module is composed of five cameras. The five cameras are evenly arranged in a circular shape on the explosion-proof housing of the high-temperature endoscope. The cameras are installed on the outer wall of the explosion-proof housing of the high-temperature endoscope in an embedded form. An image acquisition and transmission channel for electrically connecting the five cameras to the thermal imaging device is also provided inside the explosion-proof housing of the high-temperature endoscope.

[0009] Still further: An installation hole is provided at the end of the explosion-proof housing of the high-temperature endoscope away from the thermal imaging device. The installation hole is communicated with the image acquisition and transmission channel, and a high-temperature resistant temperature measuring device is embeddedly installed inside it.

[0010] Still further: An installation handle is provided on the XY-axis transmission mechanism.

[0011] Still further: A protective cover is fixed inside the water-cooled substrate. A receiving hole is provided at the center of the protective cover opposite to the through hole.

[0012] Still further: A water-cooling circulation sandwich layer and a wind-cooling sandwich layer are respectively arranged inside the explosion-proof housing of the high-temperature endoscope from the inside to the outside. The wind-cooling sandwich layer is communicated with the air blowing holes, and the water-cooling circulation sandwich layer is communicated with the water inlet and the water outlet respectively.

[0013] Still further: The distributed optical aperture system is composed of a multi-optical lens module, an electronic control unit, a central processor, an image synthesis algorithm module, an image stitching processing unit, a distributed optical aperture image output module, an electronic terminal display, and an image and data storage unit. The multi-optical lens module and the electronic control unit are both electrically connected to the central processor. The information collected by the central processor through the multi-optical lens module and the electronic control unit is sequentially processed by the image synthesis algorithm module and the image stitching processing unit and then sent to the distributed optical aperture image output module. The distributed optical aperture image output module displays the panoramic image through the electronic terminal display and stores and records it through the image and data storage unit.

[0014] Even further: The five cameras in the multi-optical lens module are respectively the first camera, the second camera, the third camera, the fourth camera, and the fifth camera. The first camera covers the area from 0° to 72°, the second camera covers the area from 72° to 144°, the third camera covers the area from 144° to 216°, the fourth camera covers the area from 216° to 288°, and the fifth camera covers the area from 288° to 360°.
