Description

Technical Field

[0001] This application belongs to the field of metallurgy, and specifically relates to a high-temperature resistant insertable supplemental endoscope. Background Technology

[0002] The fire assay furnace is a commonly used experimental device for metal testing, especially for determining the content of gold, silver, and other precious metals. The process involves placing the lead coin into an ash pan preheated at 900℃ for 20 minutes in the furnace. The furnace door is closed, and the temperature is maintained at 900℃ until the lead coin is completely melted. Then, the temperature is controlled at approximately 860℃ for further ash blowing, which takes about one hour. The completion of ash blowing is indicated by two flashes of light on the coin.

[0003] Existing automated ash blowing furnaces typically use a high-temperature resistant endoscope inserted into the furnace chamber to monitor the ash trays in real time, recording any trays exhibiting flashing phenomena, which are then removed manually or by automated mechanical grippers. However, due to the dim lighting inside the furnace chamber, in actual monitoring, the high-temperature resistant endoscope struggles to accurately monitor the current ash blowing process and the tray numbers. Furthermore, when flashing phenomena occur, the significant changes in brightness make it difficult for the endoscope camera to adjust its brightness instantly, resulting in a "blinding" effect. The accuracy of image monitoring is also compromised, and traditional supplementary lighting is ill-suited for prolonged operation at such high temperatures.

[0004] Therefore, a supplemental lighting endoscope for the furnace cavity is needed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of the prior art, this application provides a high-temperature resistant insertable supplemental endoscope that can provide illumination inside the furnace cavity for imaging, thereby improving reliability.

[0006] The technical effect to be achieved in this application is accomplished through the following solution:

[0007] According to a first aspect of this application, a high-temperature resistant insertable supplemental lighting endoscope is provided, comprising an endoscope, the endoscope being installed in a cooling cylinder, the cooling cylinder being provided with a circulation pipe, the circulation pipe being provided with a cooling medium, a supplemental lighting lamp being provided next to the endoscope, the endoscope and the supplemental lighting lamp being arranged facing the opening at the bottom of the cooling cylinder, the bottom opening of the cooling cylinder being sealed with heat-insulating glass, and a telescopic mechanism being installed on the cooling cylinder, the telescopic mechanism being used to drive the cooling cylinder to rise and fall to insert or pull out of the furnace cavity.

[0008] Preferably, the circulation pipeline includes an air-cooled pipeline and a water-cooled pipeline, with the water-cooled pipeline located outside the air-cooled pipeline.

[0009] Preferably, the cooling cylinder includes several nested sleeves, the gap between the sleeves forms the water-cooling pipeline, the water-cooling pipeline is an S-shaped loop arranged along the length of the cooling cylinder, and an inlet and an outlet connected to the water-cooling pipeline are provided outside the cooling cylinder.

[0010] Preferably, the gap between the inner cavity of the cooling cylinder and the supplementary light is the air-cooling pipeline, and the top of the cooling cylinder is provided with an air inlet and an air outlet.

[0011] Preferably, the telescopic mechanism includes a fixed cylinder, the cooling cylinder is slidably connected to the fixed cylinder, the upper and lower ends of the cooling cylinder extend out of the fixed cylinder, and a driving mechanism is provided in the fixed cylinder for driving the cooling cylinder.

[0012] Preferably, the driving mechanism includes a piston ring, which is sleeved in the middle of the cooling cylinder. The piston ring divides the fixed cylinder into an upper sealing cavity and a lower sealing cavity, and both the upper sealing cavity and the lower sealing cavity are connected to a compressed air pipe.

[0013] Preferably, an adapter is fixed to the top of the cooling cylinder, and the wiring of the supplementary light and the endoscope are both connected to the adapter.

[0014] According to one embodiment of this application, the advantages of using this high-temperature resistant insertable supplementary lighting endoscope are that it can be inserted into the furnace cavity for supplementary lighting and then taken pictures, which can improve the clarity and reliability of the monitoring process; the insertable structure can be pulled out when no pictures are needed, and only inserted when pictures are needed, resulting in a longer service life; the multiple cooling structure can slow down the aging of circuits and precision components, thereby greatly improving the service life.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figures 1 to 3 As shown, a high-temperature resistant insertable supplemental lighting endoscope in one embodiment of this application includes an endoscope 101. The endoscope 101 is installed in a cooling cylinder 200, which has a circulation pipe containing a cooling medium. A supplemental lighting lamp 102 is positioned next to the endoscope 101. Both the endoscope 101 and the supplemental lighting lamp 102 are arranged facing the opening at the bottom of the cooling cylinder 200. The bottom opening of the cooling cylinder 200 is sealed with heat-insulating glass 110. A telescopic mechanism 300 is installed on the cooling cylinder 200, which drives the cooling cylinder 200 to rise and fall to insert into or remove from the furnace cavity.

[0022] In this embodiment, a cooling medium circulates in the circulation pipeline to continuously cool the cooling cylinder 200, preventing the supplementary light 102 and endoscope 101 inside the cooling cylinder 200 from being damaged due to excessive temperature or damage to the wiring. This greatly improves their service life, ensures reliable illumination of the furnace cavity, improves the clarity of the images, and makes the judgment more accurate. The telescopic mechanism 300 can pull the supplementary light 102 and endoscope 101 out of the furnace cavity when not in use, avoiding the impact of prolonged high temperature on their service life.

[0023] A heat-insulating glass 110 is fixed to the bottom opening of the cooling cylinder 200. The heat-insulating glass 110 is a double or triple layer of high-temperature resistant glass, which seals the cooling cylinder 200 to prevent heat from being discharged from the furnace cavity through the cooling cylinder 200; and can further insulate against high temperatures to prevent damage to the supplementary light 102 and the endoscope 101.

[0024] In one embodiment of this application, the circulation pipeline includes an air-cooled pipeline 220 and a water-cooled pipeline 210, with the water-cooled pipeline 210 located outside the air-cooled pipeline 220. The water-cooled pipeline 210 can remove most of the heat, preventing the high temperature inside the furnace cavity from being transferred to the inner cavity of the cooling cylinder 200. The air-cooled pipeline 220 can further exhaust the hot air around the supplementary light 102 and the endoscope 101, thereby ensuring that the supplementary light 102 operates at a lower temperature. Compared with a single cooling method, setting up two sets of cooling circulation pipelines not only has higher cooling efficiency but also higher reliability, greatly improving the service life of the supplementary light 102.

[0025] In one embodiment of this application, the cooling cylinder 200 includes a plurality of nested sleeves 201. The gaps between the sleeves 201 form a water-cooling pipeline 210. The water-cooling pipeline 210 is an S-shaped loop arranged along the length of the cooling cylinder 200. An inlet 211 and an outlet 212 communicating with the water-cooling pipeline 210 are provided outside the cooling cylinder 200. The cooling cylinder 200 is made of materials such as iron or copper. Cooling is performed directly on the outer wall of the cooling cylinder 200, effectively isolating heat transfer from external high temperatures, resulting in better cooling performance.

[0026] In one embodiment of this application, the gap between the inner cavity of the cooling cylinder 200 and the supplementary light 102 is an air-cooled pipe 220. The top of the cooling cylinder 200 is provided with an air inlet 221 and an air outlet 222. Compressed air is introduced into the air-cooled pipe 220, which can directly blow cold air into the vicinity of the supplementary light 102 and the endoscope 101, and can also remove water vapor and other substances generated during the cooling process, thus avoiding affecting the lifespan of the supplementary light 102 and the endoscope 101.

[0027] In one embodiment of this application, the telescopic mechanism 300 includes a fixed cylinder 310, and the cooling cylinder 200 is slidably connected to the fixed cylinder 310. The upper and lower ends of the cooling cylinder 200 extend out of the fixed cylinder 310. A driving mechanism is provided in the fixed cylinder 310 for driving the cooling cylinder 200. The fixed cylinder 310 can be fixed to the furnace body and allows axial movement of the cooling cylinder 200, enabling the insertion and extension of the supplementary lighting 102 and the endoscope 101.

[0028] In one embodiment of this application, the driving mechanism includes a piston ring 320, which is sleeved on the middle of the cooling cylinder 200. The piston ring 320 divides the fixed cylinder 310 into an upper sealing cavity 301 and a lower sealing cavity 302. Both the upper sealing cavity 301 and the lower sealing cavity 302 are connected to compressed air pipes 303. Injecting compressed air into the upper sealing cavity 301 or the lower sealing cavity 302 will push the piston ring 320 to move the entire cooling cylinder 200, thereby enabling the up-and-down movement of the endoscope 101 and the supplementary light 102.

[0029] In one embodiment of this application, an adapter 120 is fixed to the top of the cooling cylinder 200, and the wiring of the supplementary light 102 and the endoscope 101 are both connected to the adapter 120. This facilitates the connection of power and signal lines, and uses flexible cables to avoid interference during movement.

[0030] According to one embodiment of this application, the beneficial effects of using this high-temperature resistant insertable supplementary lighting endoscope are that it can be inserted into the furnace cavity for supplementary lighting and monitoring, which greatly improves the shooting effect and the accuracy of visual recognition; the use of two sets of cooling devices can greatly improve the cooling effect and extend the service life of the endoscope and supplementary lighting lamp; when monitoring is not required, it can be pulled out of the furnace cavity, which greatly extends the service life.
