Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and in particular to an infrared ranging endoscope for measuring cavity size. Background Art

[0002] At present, ground-penetrating radar technology has been widely used in the field of non-destructive detection of road defects. Ground-penetrating radar technology can quickly, comprehensively and accurately "see through" road soil defects such as voids, looseness, and water-rich soil. During the implementation of road inspection projects, suspected voids, voids and other defects screened out through data analysis need to be verified by drilling. After the drilling verification, the hole needs to be photographed or filmed. At the same time, engineers measure the buried depth and net depth of the void from the ground and inside the hole.

[0003] In the traditional workflow, after taking photos or videos with an endoscope, the endoscope lens needs to be inserted into the hole and marked on the coil when it reaches the top and bottom of the hole. Then, the endoscope is taken out and a tape measure is used to measure the top of the first hole as the hole burial depth, and the bottom of the second hole as the hole bottom burial depth. The difference between the two is the hole clearance. Then the length and width of the hole are measured from the ground. This is quite troublesome. In addition, when collecting images, the endoscope is generally suspended in the air without support inside the hole. If the operator has hand tremors, the collected image will appear blurred, which is inconvenient to use. Summary of the Invention

[0019] The present invention provides an infrared ranging endoscope for cavity size measurement through improvement. Compared with the prior art, it has the following improvements and advantages:

[0020] First: The present invention sets a supporting mechanism. When the probe goes deep into the cavity to measure the size through the infrared ranging lens, the interior of the airbag can be inflated through the inflation tube. After the airbag is inflated, it will expand inside the limit seat. After the airbag expands, it will squeeze the mounting block. After the mounting block is squeezed, it will drive the support rod to move, and the support rod can then drive the base to extend from the inside of the collecting tank. Since two connecting magnetic blocks are embedded in the supporting feet, when the base and the supporting feet leave the inside of the collecting tank, the two supporting feet will flip to both sides under the repulsive force of the connecting magnetic blocks, and then the flipped supporting feet will contact the inner wall of the cavity, thereby supporting and fixing the probe, improving the stability during measurement, and ensuring the accuracy of the data.

[0021] Secondly: In the present invention, when the measurement is completed, the air inside the airbag is released through the inflation tube. Since a return spring is sleeved on the support rod, the return spring will be compressed when the mounting block and the support rod move. When the airbag is deflated, the return spring will release the elastic force, which can make the mounting block reset downward, thereby driving the base and the support feet back to the inside of the collection tank. Since the two support feet are open, when the support feet contact the inner wall, a certain sample can be collected from the inner wall of the cavity. Then, when the support feet return to the collection tank, the support feet will be squeezed by the collection tank, so that the two support feet fit together, and the sample can be stored inside the support feet. After taking the probe out of the cavity, it can be inflated again to make the support feet open, and then the sample inside the cavity can be obtained, thereby achieving the effect of automatically collecting samples after measuring data inside the cavity.

[0022] Third: The present invention is provided with a cleaning mechanism. When the mounting block is moved by inflating the airbag, since one end of the transmission plate is located inside the limit seat, when the mounting block moves upward, it will drive the transmission plate to move, and the movement of the transmission plate will squeeze the corrugated hose. After being squeezed, the corrugated hose will transport the internal air to the inside of the air blowing tube. The air blowing tube can then blow the air into the inside of the image acquisition lens, thereby cleaning the surface of the image acquisition lens and blowing off the dust on the surface of the image acquisition lens. Subsequently, the dust-laden air can be discharged from the inside of the image acquisition lens through the exhaust port, thereby achieving the effect of automatically cleaning the image acquisition lens before collecting data, thereby ensuring the clarity of the image when collecting.

[0023] Fourthly: In the present invention, the push block can be driven to move by pushing the slider to move inside the slide groove. The movement of the push block can squeeze the display screen, so that the display screen can be flipped with the torsion spring axis as the base point. The position of the slider can then be fixed by the fixing mechanism on the slider. At this time, the angle of the display screen will be fixed, thereby achieving the effect of freely adjusting the use angle of the display screen, making it easy to find the best viewing angle when using it.

[0024] Fifth: The present invention can bend the semi-rigid coiled tube through the setting of the storage mechanism, so that the semi-rigid coiled tube is threaded, and then the semi-rigid coiled tube can be stored inside the storage groove. Then, the buckle on the limit belt is buckled with the buckle on the endoscope host, so that the bottom of the semi-rigid coiled tube can be supported, thereby achieving the effect of storing the semi-rigid coiled tube, reducing the volume of the device when stored, and facilitating storage.

Since the two supporting feet 16 are open, when the supporting feet 16 contact the inner wall, a certain sample can be collected from the inner wall of the cavity. Then, when the supporting feet 16 return to the collecting tank 14, the supporting feet 16 will be squeezed by the collecting tank 14, so that the two supporting feet 16 fit together, and the sample can be stored inside the supporting feet 16. After taking the probe 4 out of the cavity, it can be inflated again to open the supporting feet 16, and then the sample inside the cavity can be obtained, thereby achieving the effect of automatically collecting samples while measuring data inside the cavity.

Since there are two connecting magnetic blocks 18 embedded on the supporting feet 16, when the base 15 and the supporting feet 16 leave the inside of the collection tank 14, the two supporting feet 16 will flip to both sides under the repulsive force of the connecting magnetic blocks 18, and then the flipped supporting feet 16 will contact the inner wall of the cavity, thereby supporting and fixing the probe 4, improving the stability during measurement, and ensuring the accuracy of the data. When the measurement is completed, the air inside the airbag 10 is filled through the inflation tube 11. When the airbag 10 is deflated, the return spring 19 releases its elastic force, which allows the mounting block 12 to return downward, thereby driving the base 15 and the support legs 16 back to the inside of the collecting tank 14. Since the two support legs 16 are open, when the support legs 16 contact the inner wall, a certain sample can be collected from the inner wall of the cavity. Subsequently, when the support legs 16 return to the collecting tank 14, the support legs 16 will be squeezed by the collecting tank 14, so that the two support legs 16 fit together, and the sample can be stored in the inside of the support legs 16.
