[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a partial structural schematic diagram of an embodiment of a pipeline periscope probe device of the present application; Figure 2 This is a schematic diagram of the overall structure of an embodiment of a pipeline periscope probe device of the present application; Figure 3 for Figure 1Schematic diagram of part of the explosion structure shown.

[0039] The present application provides a pipeline periscope probe device, which includes a probe body 10 and a frame 20. The probe body 10 includes a shooting component 110, and a plurality of light source components 120 and a distance measuring component 140 arranged at intervals around the shooting component 110. The irradiation area of ​​the light source component 120 is consistent with the shooting area of ​​the shooting component 110, and the angle between the distance measuring component 140 and the shooting component 110 is set so that the distance measuring component 140 measures the distance between the center of the shooting area and the probe body 10. The frame 20 is connected to the probe body 10, and a battery module 210 is provided on the frame 20 for powering the probe body 10. In an embodiment of the present application, the shooting component 110 may include a camera, which is used to shoot the area irradiated by the light source component 120, and the distance measuring component 140 is used to measure the distance between the center of the area shot by the light source component 120 and the probe body 10. It can be understood that, with the probe body 10 as the center, the area around the probe body 10 can be illuminated, because the shooting area of ​​the shooting component 110 is consistent with the irradiation area of ​​the light source component 120, and the image obtained is clearer. And while shooting, the distance measuring component 140 can measure the shooting area in real time, which is more convenient for future maintenance work in the pipeline. Please refer to Fig. 9 The distance measuring component 140 and the shooting component 110 are set at an angle, so that the light emitted by the distance measuring component 140 is directly facing the center of the shooting area of ​​the shooting component 110, and thus the distance value between the shooting area and the probe body 10 measured by the distance measuring component 140 is more accurate.

[0040] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 4 for Figure 1 A front view of a probe body in a pipeline periscope probe device shown; Figure 5 for Figure 4 A cross-sectional view of a state at AA in the middle; Figure 6 for Figure 4 A cross-sectional view of another state at AA in the figure, Figure 7 for Figure 1The schematic diagram of the structure of the mounting frame 1310 in the pipeline periscope probe device is shown. The pipeline periscope probe device also includes a detection mechanism 130. The probe body 10 is provided with a matching groove 150 and a threading groove 160 connected to the matching groove 150. The detection mechanism 130 includes a mounting frame 1310 placed in the matching groove 150, a gas sensor 1320 connected to the mounting frame 1310, and a filter 1330 covering the matching groove 150. The filter 1330 is used to filter impurities outside the detection mechanism 130. The gas sensor 1320 is used to detect volatile organic compound gas. The gas sensor 1320 is connected to the gas sensor 1320. The cable passes through the threading groove 160 and is electrically connected to the circuit board 1920 arranged in the probe body 10; the bottom of the matching groove 150 also includes a sealing groove 190, and the bottom of the mounting frame 1310 is provided with a sealing member 1910 adapted to the sealing groove 190, so that when the detection mechanism 130 and the probe body 10 are in the matched state, the threading groove 160 is not connected to the outside world; the sealing member 1910 is a sealing ring, and the circumferential dimensions of the matching groove 150, the sealing groove 190 and the threading groove 160 decrease successively, and the size of the bottom of the sealing member 1910 is adapted to the size of the sealing groove 190.

[0041] The close fit between the sealing ring and the sealing groove 190 can make the threading groove 160 not connected to the outside world, and then the gas detected by the gas sensor 1320 and the small molecule water doped in the gas will not enter the probe body 10 through the threading groove 160, thereby protecting the components inside the probe body 10 from damage, and the residual gas in the probe body 10 will not enter the gas sensor 1320 through the threading groove 160, and then the gas detected by the gas sensor 1320 is all from the gas after passing through the filter 1330 in the pipeline, thereby improving the detection accuracy of the gas sensor 1320. In one embodiment of the present application, the sealing ring can be made of rubber, and the circumferential size of the sealing ring can be larger than the size of the sealing groove 190, and then the sealing ring and the sealing groove 190 can be interference fit to improve the sealing effect of the sealing ring. It can be understood that the shooting assembly 110, the light source assembly 120, the detection mechanism 130, the battery module 210 and the distance measurement assembly 140 are all electrically connected to the circuit board 1920 set in the probe body 10.

[0042] Furthermore, the opposite sides of the mating groove 150 also include avoidance grooves 1510, the probe body 10 is provided with a plurality of first mating holes 1520 in the avoidance grooves 1510, and the mounting frame 1310 is provided with a plurality of second mating holes 1340 corresponding to the first mating holes 1520, and the screws pass through the second mating holes 1340 and the first mating holes 1520 in sequence to lock the mounting frame 1310 and the probe body 10.

[0043] In one embodiment of the present application, the filter element 1330 is a breathable film, and a plurality of filter holes are provided on the breathable film for filtering sewage and impurities; the material of the breathable film is Teflon. The setting of the breathable film allows toxic gases smaller than the filter holes to enter the gas sensor 1320 for detection, while macromolecular impurities larger than the size of the toxic gas cannot enter the gas sensor 1320, which is convenient for improving the detection accuracy of the gas sensor 1320. The gas sensor 1320 is a solid polymer gas sensor 1320, which uses the principle of electrochemical gas detection to measure a variety of gases decomposed by chemical decomposition and output a digital signal corresponding to the gas concentration value, which can be processed by the corresponding integrated circuit (not shown) on the circuit board 1920. Then the circuit board 1920 is connected to the terminal device through wireless communication, and the corresponding gas concentration value can be displayed on the terminal device. It should be noted that the wireless communication is Bluetooth communication or WiFi communication.

[0044] In one embodiment of the present application, the detection range of the gas sensor 1320 is 0-500 ppm.

[0045] Please refer to Figure 3 and Figure 8 , Figure 8 for Figure 4 Cross-sectional view at BB in the middle. In one embodiment of the present application, there are four light source assemblies 120, and the light source assemblies 120 include a lamp holder 1210 and lamp beads 1220 disposed in the lamp holder 1210, and the light emitting direction of the lamp beads 1220 is arranged parallel to the light emitting direction of the shooting assembly 110. Because the light emitting direction of the lamp beads 1220 is arranged parallel to the light emitting direction of the shooting assembly 110, the area photographed by the shooting assembly 110 corresponds to the irradiation area of ​​the light source assembly 120, and the clarity of the image formed by the shooting assembly 110 will be higher.

[0046] The probe body 10 is provided with a first installation channel 170 for placing a camera and a plurality of second installation channels 180 for placing a light source assembly 120, and the extension direction of the first installation channel 170 is consistent with the extension direction of the second installation channel 180. Because the first installation channel 170 and the second installation channel 180 extend in the same direction, the light emitting directions of the camera and the light source assembly 120 respectively installed in the first installation channel 170 can be consistent.

[0047] The lamp holder 1210 is conical, and the circumferential dimension of the end facing the lamp bead 1220 is smaller than the circumferential dimension away from the lamp bead 1220. Such a configuration can make the light emitted from the lamp bead 1220 illuminate a larger area, and when multiple lamp beads 1220 illuminate an area at the same time, the overall brightness of the area is superimposed, and then when the camera assembly 110 shoots it, the image formed by the shooting will be clearer.

[0048] Please continue to refer to Figure 3 A first sealing plate 1230 is provided on the side of the lamp holder 1210 away from the lamp bead 1220, which is used to seal the lamp bead 1220; a second sealing plate 1110 is provided on the light emitting side of the shooting assembly 110, which is used to seal the shooting assembly 110. This arrangement can prevent impurities in the pipeline from affecting the light emitting of the shooting assembly 110 and the light source assembly 120. It can be understood that both the first sealing plate 1230 and the second sealing plate 1110 can be glass plates for easy light transmission.

[0049] The distance measuring component 140 uses laser for distance measurement. The angle between the light emitting direction of the laser and the light emitting direction of the shooting component 110 is set, so that the distance measured by the laser can be the distance between the center point of the area photographed by the shooting component 110 and the probe body 10, so that the distance measuring component 140 can measure the distance between the probe body 10 and the shooting area with higher accuracy.

[0050] Please continue to refer to Figure 1 and Figure 2 The frame 20 includes a first rod 220, a second rod 230 and a mounting seat 240. The first rod 220 and the second rod 230 are spaced apart on both sides of the probe body 10. The mounting seat 240 is connected between the first rod 220 and the second rod 230, and the battery module 210 is mounted on the mounting seat 240. The first rod 220 and the second rod 230 are respectively located on opposite sides of the probe body 10, so that the stability of the probe body 10 during the descent process is higher. In one embodiment of the present application, a buffer 30 is also included. The buffer 30 is used to elastically buffer the probe body 10. When the probe body 10 is impacted by the outside world, the setting of the buffer 30 can elastically buffer it to reduce the degree of damage to the probe body 10.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
