[0002] Multi-mode detection technology is a technology that integrates multiple detection technologies, aiming to improve detection accuracy, reliability and flexibility. Because it can maintain good performance under different environmental conditions, can adapt to various complex application scenarios, provide more information and analysis perspectives, reduce the limitations of a single mode, and can fuse data of multiple detection modes, it is used in the fields of environmental monitoring, industrial inspection and medical imaging, and also has applications in pipeline detection.

[0003] Pipeline detection includes the detection of gas pipelines, which is a key link to ensure the safe operation of the gas system. Ground penetrating radar, magnetic detection and ultrasonic detection are mostly used. Among them, magnetic detection has great constraints and can only detect metal pipelines, is ineffective for non-metal pipelines, and is affected by the surrounding magnetic field. Ultrasonic detection needs to be in contact with the pipeline to complete the detection. Therefore, the application of multi-mode detection technology enables it to adapt to different environments and types of pipelines.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] Please refer to the attached Figure 1 - attached Figure 3 As shown in the figure, an embodiment provided by the present invention: A precise detection device for gas pipelines based on multi-mode detection technology, including a hollow shell 1. Slide grooves 5 are opened on both the left and right sides of the hollow shell 1. Guide grooves 9 are opened on the rear sides of the bottom of the hollow shell 1. A guide rod 11 is slidably connected to the inner wall of the guide groove 9. The top end of the guide rod 11 is fixedly connected to a slide bar 18. The outer end of the slide bar 18 is fixedly connected to a protection cover 3. The bottom end of the guide rod 11 is fixedly connected to a link rod 10. The bottom of the link rod 10 is rotatably connected to a rotating rod 13. The middle part of the inner wall of the rotating rod 13 is rotatably connected to a limit block 8. The lower middle side of the outer wall of the rotating rod 13 is fixedly connected to a spring 12. The bottom end of the hollow shell 1 is fixedly connected to a replacement device 2, and the replacement device 2 is used to replace different sensing modules. The top of the hollow shell 1 is fixedly connected to a screen 20. A nameplate 17 is fixedly connected to the front side of the hollow shell 1 near the edge.

[0034] Specifically, the relevant information of the device is marked on the nameplate 17, which is convenient for users to identify and manage. The screen 20 is used to display the detection data and the device status in real time. The protection cover 3 can protect the screen 20 and the electronic devices below it from being damaged during collisions and falls. The limit block 8 can limit the rotation of the rotating rod 13 so that it rotates within a certain range, thereby ensuring the pushing out and resetting of the protection cover 3. The rotational connection between the link rod 10 and the rotating rod 13 can convert the applied force into a horizontally moving force, so that the guide rod 11 drives the slide bar 18 to slide in the slide groove 5.

[0035] Please refer to the attached Figure 4 - attached Figure 6, the replacement device 2 includes a wire 201. The left end of the wire 201 is fixedly connected to the bottom end of the hollow housing 1. The right end of the wire 201 is fixedly connected to a mounting plate 202. A plurality of clamping blocks 204 are fixedly connected to the outer wall of the mounting plate 202. A sliding nut 203 is arranged on the outer wall of the wire 201. The inner wall of the sliding nut 203 is slidably connected to the outer wall of the wire 201. A sensor 205 is arranged on the outer wall of the mounting plate 202. A card slot 206 is opened on the front side of the top of the sensor 205. A thread 207 is opened on the outer wall of the card slot 206. A handle 15 is fixedly connected to the middle of the sensor 205. An anti-slip pad 6 is fixedly connected to the inner wall of the handle 15;

[0036] Specifically, the sliding nut 203 can be connected to the thread 207, so as to fix the wire 201 and the mounting plate 202 fixedly connected to its right end on the sensor 205. A handle 15 is also fixedly connected to the middle of the sensor 205, which is convenient for the user to pick it up during detection. At the same time, an anti-slip pad 6 is fixedly connected to its inner wall to prevent the sensor 205 from falling and being damaged due to the user's slippery hand.

[0037] Please refer to the appendix Figure 2 - appendix Figure 4 , an observation window 14 is fixedly connected to the top of the protective cover 3. A hanging ring 19 is fixedly connected to the front side of the hollow housing 1. Contact points 4 are fixedly connected to the inward sides of the mounting plate 202 and the thread 207. The outer wall of the clamping block 204 is slidably connected to the inner wall of the card slot 206. A controller 16 is fixedly connected to the middle of the front side of the hollow housing 1. The outer wall of the sliding rod 18 is slidably connected to the inner wall of the chute 5. A handle 21 is fixedly connected to the bottom of the rotating rod 13. A protective shell 7 is fixedly connected to the middle of the rear side of the hollow housing 1;

[0038] Specifically, the observation window 14 can facilitate the user to observe the detection result on the screen 20 when operating without opening the protective cover 3. The contact point 4 can electrically connect the mounting plate 202 and the sensor 205, so as to transmit data from the wire 201 to the hollow housing 1. The handle 21 can facilitate the user to press the rotating rod 13 to move the protective cover 3. The hanging ring 19 can allow the user to hang and store the hollow housing 1.

[0039] Working principle: After taking out the detector from the protection box, the user holds the middle part of the hollow housing 1 with one hand and holds the handle 15 with the other hand. When it is necessary to read the measurement result, press the grip 21 to make the rotating rod 13 press down, rotate along the limit block 8, and compress the spring 12 to store energy. At the same time, the connecting rod 10 drives the guide rod 11 to slide forward in the guide groove 9, so as to slide the sliding rod 18 fixedly connected thereto together in the sliding groove 5, and move the protective cover 3 fixedly connected thereto together, so that the screen 20 is exposed. When the hand is released after reading the data or accidentally slips off, the rotating rod 13 is released, and the energized spring 12 presses and rotates the rotating rod 13 in the opposite direction, so as to reset the protective cover 3 to protect the screen 20 and the structure at its bottom;

[0040] When a single sensor 205 cannot meet the detection requirements, twist the sliding nut 203 to disconnect it from the thread 207, then rotate the mounting plate 202 to rotate the block 204 to the notch of the card slot 206, so as to disconnect the mounting plate 202 from the card slot 206. After replacing the required sensor 205, make the contacts 4 on the mounting plate 202 fit with the contacts 4 on the sensor 205, and rotate the mounting plate 202 and the sliding nut 203 to re - engage them.

[0041] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacement of some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
