Description

Technical Field

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

[0002] At present, ground penetrating radar technology has been widely used in the field of non-destructive detection of road diseases. Ground penetrating radar technology can quickly, comprehensively, and accurately "penetrate" soil disease information such as road cavities, looseness, and water-rich areas. During the implementation of road detection projects, for suspected diseases such as cavities and voids screened through data analysis, drilling means are required for hole verification. After hole verification, it is necessary to take pictures or videos inside the hole. At the same time, engineers measure the buried depth and net depth of the cavity from the ground and inside the hole.

[0003] In the traditional work process, after the endoscope takes pictures or videos, it is also necessary to mark on the snake tube respectively when the endoscope lens is inserted into the hole to reach the top and bottom of the cavity. Then, the endoscope is taken out and a tape measure is used to measure the first mark at the top of the cavity as the buried depth of the cavity, and the second mark at the bottom as the buried depth of the bottom of the cavity. The difference between the two is the cavity clearance. Then, the length and width dimensions of the cavity are measured from the ground, which is relatively troublesome. And when collecting images, the endoscope is generally suspended without support inside the cavity. If the operator's hand shakes, the collected images will be blurred and other situations, making it inconvenient to use. Summary of the Invention

[0015] The present invention provides an infrared ranging endoscope for cavity size measurement by improvement. Compared with the prior art, it has the following improvements and advantages: First: Through the setting of the support mechanism of the present invention, when the probe penetrates into the cavity and the size is measured through the infrared ranging lens, the inside of the airbag can be inflated through the inflatable tube. After the airbag is inflated, it will expand inside the limit seat. After the airbag expands, it will squeeze the installation block. After the installation block is squeezed, it will drive the support rod to move. The support rod can then drive the base to extend out of the collection groove. Since two connecting magnetic blocks are inlaid on the support feet, when the base and the support feet leave the inside of the collection groove, the two support feet will flip to both sides under the repulsive force of the connecting magnetic blocks, and then the flipped support feet will contact the inner wall of the cavity, so as to support and fix the probe, improve the stability during measurement, and ensure the accuracy of the data.

[0016] Second: In the present invention, after the measurement is completed, the air inside the airbag is released through the inflatable 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. After the airbag is deflated, the return spring will release elastic force, which can then cause the mounting block to return downward, thereby driving the base and the support feet back into the collection groove. 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. Subsequently, when the support feet return to the collection groove, the support feet will be squeezed by the collection groove, causing the two support feet to fit together, and thus the sample can be stored inside the support feet. After taking out the probe from the cavity, the airbag can be inflated again to make the support feet open, and then the sample inside the cavity can be obtained. Therefore, after the data measurement of the cavity is completed, the effect of automatically collecting samples can be achieved at the same time.

[0017] Third: In the present invention, through the setting of the cleaning mechanism, when the airbag is inflated to drive the movement of the mounting block, 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 the corrugated hose is squeezed, it will transport the air inside to the inside of the air blowing tube, and 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 air with dust can be discharged from the inside of the image acquisition lens through the exhaust port, and thus the effect of automatically cleaning the image acquisition lens before data acquisition is achieved, ensuring the clarity of the acquired images.

[0018] Fourth: In the present invention, by pushing the slider to move inside the chute, the push block can be driven to move. The movement of the push block can squeeze the display screen, causing the display screen to flip with the torsion spring shaft as the base point. Subsequently, the position of the slider can be fixed through the fixing mechanism on the slider. At this time, the angle of the display screen will be fixed, and thus the effect of freely adjusting the use angle of the display screen is achieved, facilitating finding the best viewing angle during use.

[0019] Fifth: In the present invention, through the setting of the storage mechanism, the semi-rigid coiled tube can be bent to make the semi-rigid coiled tube in a spiral shape, and then the semi-rigid coiled tube can be stored inside the storage groove. Subsequently, the buckle on the limit belt is buckled with the buckle on the endoscope host, thereby supporting the bottom of the semi-rigid coiled tube, achieving the effect of storing and accommodating the semi-rigid coiled tube, reducing the volume of the device during storage, and facilitating storage.

When the measurement is completed, the air inside the airbag 10 is released through the inflation tube 11. Since the return spring 19 is sleeved on the support rod 13, the return spring 19 will be compressed when the mounting block 12 and the support rod 13 move. When the airbag 10 is deflated, the return spring 19 will release the elastic force, thereby enabling the mounting block 12 to return downward, driving the base 15 and the support feet 16 back into the collection groove 14. Since the two support feet 16 are open, when the support feet 16 contact the inner wall, a certain sample can be collected from the inner wall of the cavity. Subsequently, when the support feet 16 return to the collection groove 14, the support feet 16 will be squeezed by the collection groove 14, causing the two support feet 16 to fit together, and the sample can be stored inside the support feet 16. After taking the probe 4 out of the cavity, the air can be inflated again to make the support feet 16 open, and then the sample inside the cavity can be obtained. Thus, the effect of automatically collecting samples while measuring the data inside the cavity is achieved.

When the measurement is completed, the air inside the airbag 10 is released through the air filling pipe 11. Since a return spring 19 is sleeved on the support rod 13, the return spring 19 will be compressed when the mounting block 12 and the support rod 13 move. When the airbag 10 is deflated, the return spring 19 will release elastic force, thereby enabling the mounting block 12 to reset downward, driving the base 15 and the support feet 16 back into the inside of the collection groove 14. Since the two support feet 16 are open, when the support feet 16 contact the inner wall, a certain sample can be collected from the inner wall of the cavity. Subsequently, when the support feet 16 return to the collection groove 14, the support feet 16 will be squeezed by the collection groove 14, causing the two support feet 16 to fit together, and the sample can be stored inside the support feet 16. After taking the probe 4 out of the cavity, the support feet 16 can be inflated again to open, and then the sample inside the cavity can be obtained. Thus, after measuring the data inside the cavity, the effect of automatically collecting samples can be achieved at the same time.
