Specifically, the mobile wheel 3 is a universal wheel, which can facilitate the actual pushing of the mobile detection frame.

[0027] The adjustable detection frame includes two top cross bars 4, four electric lifting rods 5 and a detection support plate 6. The two ends of the top cross bars 4 are fixedly connected to the inner side of the external rectangular frame 1. The bottom of one top cross bar 4 is respectively connected to the top of the two electric lifting rods 5. The bottom ends of the four electric lifting rods 5 are respectively fixedly connected to the four top corners of the detection support plate 6. The pipeline detector 7 is placed on the detection support plate 6. The detection support plate 6 is provided with a detection hole for the probe of the leaked pipeline detector 7. The electric lifting column can be extended and retracted, so that the detection support plate 6 can be raised and lowered to avoid obstacles. Among them, the pipeline detector 7 adopts the pipeline detector 7 host finished product already available on the market. The utility model mainly re-upgrades the design of the pipeline detector as a whole, especially the overall obstacle avoidance structure.

[0028] The marking mechanism includes a marking tank 8, the side of which is fixedly connected to the rear end of the detection support plate 6, and a spray valve 9 is provided at the bottom end of the marking tank 8;

[0029] like Figure 2 As shown, the display and control mechanism includes an operation panel body 10, a display screen 11, a button panel 12 and two hand grips 13. The operation panel body 10 is horizontally fixedly installed at the rear end of the external rectangular frame 1.

Specifically, the bottom end of the display screen 11 is connected to the top front end of the operation panel body 10 through a damping shaft 18. The staff can adjust the angle of the display screen 11 according to actual viewing needs, and the damping shaft 18 can maintain the angle of the display screen 11, so that it can be suitable for staff with different heights and observation needs.

[0030] The button panel 12 is connected to the top of the operation panel body 10 , and the hand grips 13 are fixedly mounted on both ends of the rear side of the operation panel body 10 .

[0031] A storage battery 14 is also placed on the detection support plate 6, and the storage battery 14 is used to provide power for all electrical devices.

[0032] It should be noted that the electric units in the utility model include an electric lifting rod 5, a pipeline detector 7, a spray valve 9, a display screen 11, a button panel 12, a warning speaker 15, a pressure switch, a material pump 20, and a mobile support column 2; all of them are powered by a battery 14, and other electric units can be controlled by the button panel 12, for example, the button panel 12 can be used to control the spray valve 9 to open the valve mark, control the material pump 20 to start to replenish the marking material for the marking tank 8, control the extension and retraction of the mobile support column 2, control the extension and retraction of the electric lifting rod 5, and so on.

[0033] The working principle, use process and technical advantages of the marking type underground pipeline detector 7 of the utility model are as follows: in actual use, the staff can control the entire mobile detection frame to move forward and control the forward direction by pushing the handhold 13 by hand. When moving forward, turn on the pipeline detector 7, and the pipeline detector 7 will display the detection results on the display screen 11, so that the staff can control the movement of the entire mobile detection frame according to the pipeline path displayed by the detection. During the movement of the mobile detection frame, the staff can use the button panel 12 to electrically control the spray valve 9 of the marking tank 8, so that the marking material can be sprayed to mark the pipeline. During the movement of the entire mobile detection frame, if an obstacle that may touch the probe of the pipeline detector 7 is encountered, and the obstacle is on the pipeline path, the electric lifting rod 5 can be controlled to shorten through the button panel 12, so that the detection support plate 6 is raised, driving the pipeline detector 7 to rise, thereby avoiding damage to the pipeline detector 7 by roadblocks, and having sufficient obstacle avoidance ability.

[0034] As an embodiment of the utility model, the adjustable detection frame is also provided with an obstacle avoidance mechanism, which includes a warning speaker 15, an obstacle touch plate 16 and two elastic trigger rods 17.

[0035] In actual operation, the barrier touch plate 16 and the detection support plate 6 are located at the same height, and the barrier touch plate 16 is located at the front end of the detection support plate 6. When there is an obstacle, the barrier touch plate 16 will touch the obstacle first. Since the mobile detection frame is still moving forward, it will be blocked by the obstacle, and the elastic trigger rod 17 will be shortened. At this time, the trigger spring is compressed, and the pressure switch is squeezed and triggered, which can control the warning speaker 15 to make a sound, reminding the staff to pay attention to avoid obstacles, and can remind the staff when there is an obstacle that may damage the pipeline detector 7, to prevent the pipeline detector 7 from being damaged due to the staff not finding the obstacle.

[0036] As an embodiment of the present utility model, Figure 4 and 5 As shown, the marking mechanism further includes a storage tank 19 and a material pump 20. The storage tank 19 is placed on the detection support plate 6. The main body of the material pump 20 is installed outside the storage tank 19. The feed end of the material pump 20 is arranged in the storage tank 19, and the discharge end of the material pump 20 is arranged in the marking tank 8. The detection support plate 6 is used as a receiving platform to place the storage tank 19 with more marking materials. It should be noted that the marking material of the utility model is a colored liquid, so the material pump 20 can be used to transfer the marking material, and the marking tank 8 can be conveniently replenished.

[0037] As an embodiment of the present utility model, Figure 3 As shown, the mobile support column 2 is an electric telescopic column, and a reinforcing connecting rod 21 is connected between the bottom ends of the two mobile support columns 2 located on the left or right side of the external rectangular frame 1, and a reinforcing connecting rod 21 is also connected between the top ends of the two mobile support columns 2 located at the front or rear end of the external rectangular frame 1. That is, the overall mobile detection frame can also be raised and lowered, which can be convenient for workers of different heights to use, and at the same time can have better obstacle avoidance capabilities. When the mobile support column 2 is extended and the electric lifting column is shortened, the height of the detection support plate 6 can be made higher, so that higher obstacles can be avoided.

[0038] like Figure 3 As shown, a buffer connecting rod 22 is also connected between the moving wheel 3 and the bottom end of the moving support column 2. The buffer connecting rod 22 includes an inner sleeve rod, an outer sleeve rod and an external buffer spring. One end of the inner sleeve rod is sleeved inside one end of the outer sleeve rod, and the other end of the inner sleeve rod and the other end of the outer sleeve rod are respectively connected to the top of the moving wheel 3 and the bottom end of the moving support column 2. The external buffer spring is sleeved on the outside of the inner sleeve rod and the outer sleeve rod, and the top and bottom ends of the external buffer spring are respectively connected to the top of the moving wheel 3 and the bottom end of the moving support column 2, which can play an elastic buffering role and reduce the vibration of the mobile detection frame, so that the staff can observe the display screen 11 more comfortably.
