Description

Technical Field

[0001] This application relates to the field of detection equipment technology, and more specifically, to a high-temperature resistant endoscope with cooling reflux. Background Technology

[0002] In industrial applications, an endoscope is a non-destructive testing (NDT) device specifically designed for industrial use. It is mainly used to observe and inspect the surface condition, defects, or foreign objects in areas that cannot be directly seen with the naked eye without disassembling or damaging the structure of the object being inspected. It is widely used in industries such as manufacturing, energy, aerospace, automotive, and power, and is a key tool for ensuring the safe operation of equipment and improving product quality.

[0003] In practice, it was found that the existing products have messy tubing when in use, and when moving the products, the tubing needs to be manually wrapped around the palm of the hand to pick it up. If the hand loosens during the subsequent picking and moving process, the tubing will fall off and easily become tangled, which is troublesome and cumbersome to deal with afterward, affecting the usage process.

[0004] In view of this, we propose a high-temperature resistant endoscope with cooling reflux. Summary of the Invention

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 - Figure 5 This application discloses a high-temperature resistant endoscope with cooling reflux, including an endoscope body 1, a support and storage assembly 2, and a rotating assembly 3. The endoscope body 1 is fixedly mounted on the top of a support 11. A connecting tube 12 is fixedly connected to the outer output end of the endoscope body 1. An insertion tube 13 is fixedly mounted on the output end of the connecting tube 12. A cooling assembly is fixedly mounted on the outer side of the insertion tube 13. The support and storage assembly 2 is located at the bottom of the support 11 and is used to store the tubing. The rotating assembly 3 is located between the support 11 and the support and storage assembly 2 and is used to rotate the support 11.

[0027] When using the device, the cooling component on the outside of the insertion tube 13 can cool the output end of the insertion tube 13 when it is inserted into the detection area, reducing the impact of high temperature on the components at the output end of the insertion tube 13 and extending its service life. At the same time, during use, the endoscope body 1 can be rotated according to the detection position and the user's habits to adapt to different detection needs and improve the user's operational flexibility. After use or when it is necessary to move to the next position for detection, the tube can be simply rolled up on the support and storage component 2 for storage, making it easy to pick up and move, and avoiding the situation where the tube falls off and gets tangled during manual storage and movement.

[0028] Reference Figure 5 and Figure 6The supporting storage component 2 includes a chassis 21. A column 23 is fixedly installed on the top of the chassis 21. A telescopic groove 24 is symmetrically fixedly installed on the outer side of the column 23. A spring 25 is fixedly installed on the inner side of the telescopic groove 24. A hemispherical block 26 is fixedly installed at the end of the spring 25. The hemispherical block 26 is slidably installed on the inner side of the slot 27. The slot 27 is opened on the outer side of the ring column 28 corresponding to the hemispherical block 26, located at the end close to the column 23. The ring column 28 is fixedly installed at the bottom of the top plate 22. The top plate 22 is installed above the chassis 21, located at the bottom of the support 11. A buckle is fixedly installed on the bottom side of the top plate 22 near the ring column 28 for securing the pipeline.

[0029] When the pipeline is stored on the support storage component 2, the pipeline will be wound up within the height range of the base 21 and the column 23 due to gravity. During storage, one end of the pipeline can be passed through the buckle and secured to improve the stability of the winding. After winding, the hemispherical blocks 26 on both sides are pressed to compress the spring 25, causing the hemispherical blocks 26 to disengage from the slot 27. At this time, the column 23 can slide into the ring column 28, thereby shortening the distance between the base 21 and the top plate 22. This can limit the width of the wound pipeline and create a compression effect. The user only needs to use one hand to hold the base 21 and the top plate 22 to pick up and move the wound support storage component 2 and the pipeline. The operation is convenient, reducing the tediousness of manually winding the pipeline and preventing the pipeline from falling off and getting tangled.

[0030] Reference Figure 1 and Figure 4 The rotating assembly 3 includes a toothed disk 31, which is fixedly mounted on the bottom of the support 11. The outer side of the toothed disk 31 is slidably mounted on the inner side of the toothed groove 32. The toothed groove 32 is opened on the top of the convex disk 33. The convex disk 33 is fixedly mounted on the top of the top plate 22 and is located between the support 11 and the top plate 22.

[0031] The user can adjust the orientation of the endoscope body 1 by lifting the support 11 upwards to disengage the toothed disc 31 from the toothed groove 32. This allows for flexible adjustment based on the actual detection content on site. Furthermore, the engagement between the toothed disc 31 and the toothed groove 32 enhances the stability of the endoscope body 1 when placed, reducing the risk of the endoscope body 1 tipping over when the tubing is pulled or moved.

[0032] Reference Figure 2 and Figure 3The cooling assembly includes an inner sleeve 14, which is coaxially fixed outside the insertion tube 13. An outer sleeve 16 is coaxially fixed outside the inner sleeve 14. An inlet port 15 is fixed inside the outer sleeve 16 and communicates with the inner sleeve 14. The end of the inlet port 15 away from the inner sleeve 14 is located outside the outer sleeve 16 and is connected to the external cooling return equipment pipeline. An outlet port 17 is provided on the outer side of the outer sleeve 16 corresponding to the inlet port 15. The outlet port 17 communicates with the outer sleeve 16 and is connected to the external cooling return equipment pipeline. A polytetrafluoroethylene sleeve 18 is fixedly provided on the outer side of the outer sleeve 16.

[0033] An inner sleeve 14 is fitted over the outside of the insertion tube 13. The inner sleeve 14 and the outer wall of the insertion tube 13 form an inner cooling channel, and the outer sleeve 16 and the outer wall of the inner sleeve 14 form an outer return channel. The spiral arrangement of the inner sleeve 14 enhances the cooling effect on the insertion tube 13. When the inlet port 15 and the outlet port 17 are connected to the cooling return device, the cooling medium enters the inner sleeve 14 through the inlet port 15 and cools the output end of the insertion tube 13 through the channel opened on the side of the inner sleeve 14 that contacts the insertion tube 13. At the same time, the heat-absorbing medium exists inside the outer sleeve 16. At this time, the end of the cooling return device connected to the outlet port 17 generates an adsorption force to carry out the heat-absorbing medium inside the outer sleeve 16 and cool it again. It is then reintroduced through the inlet port 15 to achieve the effect of recycling. At the same time, the polytetrafluoroethylene sleeve 18 isolates the external high temperature from the temperature of the cooling components and the insertion tube 13, thus achieving a heat insulation effect.

[0034] In summary, the high-temperature resistant endoscope with cooling reflux disclosed in this application, when in use, utilizes a cooling component located on the outside of the insertion tube 13 to cool the output end of the insertion tube 13 as it extends into the detection area. This reduces the impact of high temperatures on the components at the output end of the insertion tube 13, extending its service life. Furthermore, during use, the endoscope body 1 can be rotated according to the detection position and the user's habits, adapting to different detection needs and improving the user's operational flexibility. After use or when moving to the next location for testing, the tubing can be easily coiled up on the support and storage component 2 for convenient handling and movement, avoiding manual handling. During the movement of the cable storage unit, if the cable becomes tangled or falls off, it will be stored on the support storage component 2. Under gravity, the cable will coil up within the height range of the base 21 and the column 23. During storage, one end of the cable can be passed through a buckle to secure it, thus improving the stability of the cable winding. After winding, pressing the hemispherical blocks 26 on both sides compresses the spring 25, causing the hemispherical blocks 26 to disengage from the slot 27. This allows the column 23 to slide into the ring column 28, shortening the distance between the base 21 and the top plate 22. This restricts the width of the wound cable and provides compression. The user can easily retrieve the wound support storage component 2 and the cable by simply gripping the base 21 and top plate 22 with one hand. The design facilitates easy movement and operation, reducing the tediousness of manually winding the tubing and preventing tubing from detaching or becoming tangled. Users can adjust the orientation of the endoscope body 1 by lifting the support 11 to disengage the toothed disc 31 from the toothed groove 32, allowing for flexible adjustments based on the actual detection requirements. The meshing of the toothed disc 31 and toothed groove 32 enhances the stability of the endoscope body 1 during placement, reducing the risk of tipping when the tubing is pulled or moved. An inner sleeve 14 is fitted over the insertion tube 13, forming an inner cooling channel with the outer wall of the insertion tube 13, and an outer return channel with the outer sleeve 16. The spiral design of the inner sleeve 14 enhances the cooling effect on the insertion tube. The cooling effect of pipe 13 is achieved when the inlet pipe 15 and outlet pipe 17 are connected to the cooling reflux device. The cooling medium enters the inner sleeve 14 through the inlet pipe 15 and cools the output end of the insertion pipe 13 through the channel opened on the side of the inner sleeve 14 that contacts the insertion pipe 13. At the same time, the heat-absorbing medium exists inside the outer sleeve 16. At this time, the end of the cooling reflux device connected to the outlet pipe 17 generates an adsorption force to carry out the heat-absorbing medium inside the outer sleeve 16 and cool it again. It is then reintroduced through the inlet pipe 15 to achieve the effect of recycling. At the same time, the polytetrafluoroethylene sleeve 18 isolates the external high temperature from the temperature of the cooling components and the insertion pipe 13, thus achieving the effect of heat insulation.
