[0045] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] like Figure 1-8As shown, a magnetic pipeline internal and external detection probe of the utility model comprises a fixing base 1, a detection member 2 and a magnetic attraction member 3, wherein a mounting opening 100 is opened on the fixing base 1; the detection member 2 is elastically arranged in the mounting opening 100, and the detection member 2 can move linearly along the height direction of the fixing base 1, and the detection member 2 has at least two detection parts 21; the magnetic attraction member 3 is arranged on the fixing base 1, and is used to adsorb the fixing base 1 on the magnetic pipeline wall; the detection member 2 is elastically displaced in the mounting opening 100, so that the corresponding detection part 21 abuts against the pipeline wall.

[0047] It should be noted that:

[0048] When the detection member 2 contacts the pipe wall, if there are any unevenness or defects on the pipe wall, the detection member 2 will undergo corresponding elastic displacement to ensure that the detection part is always in close contact with the pipe wall. Since the detection member 2 can undergo elastic displacement in the installation opening 100, it can adapt to the unevenness or curvature of the pipe wall, thereby increasing the applicability and detection stability of the probe.

[0049] This embodiment also includes a plurality of guide members 4, connecting members 5, elastic members 6 and pressure plates 7, wherein a plurality of grooves 110 are provided on the fixing seat 1, and the plurality of grooves 110 are arranged on both sides of the mounting opening 100 and are all connected to the mounting opening 100; a plurality of guide members 4 are respectively arranged in the corresponding grooves 110 and are arranged vertically to the fixing seat 1; a plurality of connecting members 5 are respectively sleeved on the outer sides of the corresponding guide members 4, and the detection member 2 is fixed between the plurality of connecting members 5 and is located in the mounting opening 100; the elastic member 6 is sleeved on the outer side of the guide member 4, and is used to make the detection member 2 elastically displaced in the mounting opening 100; a plurality of pressure plates 7 are detachably connected to one side of each groove 110, and are used to limit the elastic member 6 in the groove 110.

[0050] It should be noted that:

[0051] The guide member 4 is arranged in the groove 110 on the fixing seat 1 and is arranged vertically with the fixing seat 1. This design ensures the stability and linearity of the detection member 2 during the movement. The guide member 4 provides a moving trajectory for the detection member 2 to ensure its linear displacement in the installation port 100 while avoiding offset or rotation. The detection member 2 is connected to the guide member 4 so that the detection member 2 can move along the guide member 4, making the detection member 2 more stable when moving in the height direction. When the detection member 2 contacts the pipe wall and is subjected to pressure, the elastic member 6 will be compressed and deformed, thereby allowing the detection member 2 to move adaptively to ensure that the detection part 21 is in close contact with the pipe wall. The pressure plate is detachably connected to one side of the groove 110 to limit the elastic member 6 in the groove 110. The function of the pressure plate 7 is to fix the elastic member 6 to prevent it from falling off or shifting during use, thereby improving the stability of the detection.

[0052] This embodiment also includes a fixing member 8, wherein the number of grooves 110 on the same side is at least two, and the at least two grooves 110 on the same side are spaced apart, and the pressure plate 7 abuts against the side of the at least two grooves 110 on the same side away from the installation port 100; a plurality of thread grooves 120 are opened on the fixing seat 1, and the thread groove 120 is located between the two grooves 110 on the same side, and one end of the fixing member 8 passes through the pressure plate 7 and extends into the thread groove 120, and is threadedly connected to the thread groove 120.

[0053] It should be noted that:

[0054] There are at least two grooves 110 on the same side, and they are spaced apart from each other. This design is to ensure that the detection member 2 can be evenly stressed during movement, thereby improving the stability of movement.

[0055] In this embodiment, the cross-sectional shapes of the fixing seat 1, the detection member 2 and the detection portion 21 are all arranged in an arc shape, and are all arranged concentrically with the pipeline.

[0056] It should be noted that:

[0057] The cross-sections of the fixing base 1, the detection member 2 and the detection part 21 are all arc-shaped, which enables them to better fit the arc-shaped wall surface of the pipeline. The arc-shaped cross-section has a larger contact area with the pipeline wall and a closer contact, thereby improving the accuracy and stability of the detection.

[0058] At least two detection parts 21 in this embodiment are symmetrically arranged along the height direction of the fixing seat 1; when the outer wall of the pipeline is detected, the connecting member 5 abuts against the inner bottom wall of the groove 110, and the two sides of the elastic member 6 abut against the connecting member 5 and the pressure plate 7 respectively, and the detection part 21 away from the pressure plate 7 abuts against the outer wall of the pipeline; when the inner wall of the pipeline is detected, the connecting member 5 abuts against the pressure plate 7, and the two sides of the elastic member 6 abut against the inner bottom wall of the groove 110 and the connecting member 5 respectively, and the detection part 21 close to the pressure plate 7 abuts against the outer wall of the pipeline.

[0059] It should be noted that:

[0060] At least two detection parts 21 are symmetrically arranged along the height direction of the fixing seat 1. The symmetrical layout ensures that the detection member 2 can effectively contact and detect the inner and outer walls of the pipeline. When the outer wall of the pipeline is detected, the two sides of the elastic member 6 are respectively abutted against the connecting member 5 and the pressure plate 7, so that the elastic member 6 can provide sufficient elastic force to enable the detection member 2 to move toward the vertical direction of the pipeline, so that the elastic member 6 is in a stressed state, and at this time, the elastic member 6 can make the detection part 21 on the detection member 2 in a stressed state closely contact with the outer wall of the pipeline, thereby completing the outer wall of the pipeline. Detection; when detecting the inner wall of the pipeline, the pressure plate 7 is removed from the fixing seat 1, and then the elastic member 6 and the detection member 2 are taken out from the guide member 4 in turn, and then the elastic member 6 is first sleeved outside the guide member 4, and then the connecting member 5 of the detection member 2 is sleeved outside the guide member 4 to abut against the elastic member 6, and finally the pressure plate 7 is fixed to the fixing seat 1. At this time, the detection member 2 is in the highest position of the groove 110, and the elastic member 6 can stably provide reverse elastic force, so that the detection part 21 on the detection member 2 contacts with the inner wall of the pipeline, thereby effectively ensuring the stability of the detection.

[0061] The present embodiment also includes at least two quick-plug connectors 9 and connecting wires 10, wherein at least two quick-plug connectors 9 are arranged on one side of the detection member 2, and at least two quick-plug connectors 9 are electrically connected to the corresponding detection parts 21 respectively; an avoidance opening 130 is opened on one side of the fixing seat 1, and the avoidance opening 130 is connected to the installation opening 100; at least two connecting wires 10 are respectively plugged into the corresponding quick-plug connectors 9, and the connecting wire 10 passes through the avoidance opening 130 on the side away from the quick-plug connector 9.

[0062] In this embodiment, a plurality of mounting grooves 140 are provided on both sides of the fixing seat 1 along its height direction, the number of magnetic suction components 3 is the same as the number of mounting grooves 140, and each magnetic suction component 3 is respectively arranged in a corresponding mounting groove 140 for adsorbing on the outer wall or inner wall of the magnetic pipe.

[0063] It should be noted that:

[0064] The number of magnetic components 3 is the same as the number of mounting slots 140, ensuring that each mounting slot 140 has a magnetic component to provide adsorption force, so that the probe can generate strong adsorption force with the pipe wall at multiple positions, thereby being more stably fixed on the pipe. When the detection component 2 is used to detect the outer wall of the pipe, the lower magnetic component 3 uses its magnetic force to adsorb the fixing base 1 to the outer wall of the pipe. When the detection component 2 is used to detect the outer wall of the pipe, the upper magnetic component 3 uses its magnetic force to adsorb the fixing base 1 to the inner wall of the pipe.

[0065] In this embodiment, the number of the magnetic attraction members 3 on the same side is at least two, and the two opposing magnetic attraction members 3 are symmetrically arranged in a vertical plane with respect to the length center point of the fixing base 1 .

[0066] It should be noted that:

[0067] The magnetic attraction members 3 symmetrically arranged on the same side can not only ensure the stability of the installation, but also ensure the centering coupling of the detection member 2.

[0068] Specifically, the magnetic attraction member 3 in this embodiment is an electromagnet.

[0069] This embodiment also includes a first roller assembly 11 and a second roller assembly 12, wherein the first roller assembly 11 and the second roller assembly 12 are both rotatably connected in the fixed seat 1, and the first roller assembly 11 and the second roller assembly 12 are distributed in high and low positions; when the inner wall of the pipeline is detected, the outer side of the first roller assembly 11 abuts against the inner wall of the pipeline; when the outer wall of the pipeline is detected, the outer side of the second roller assembly 12 abuts against the outer wall of the pipeline.

[0070] It should be noted that:

[0071] The first roller assembly 11 and the second roller assembly 12 are provided to reduce the friction resistance of the device when it moves on the pipe wall, making the entire detection process more stable and smooth.

[0072] Working principle:

[0073] When inspecting the outer wall of the pipeline, the connecting member 5 of the inspection member 2 is at the lowest position of the groove 110. When the inspection member 2 abuts against the outer wall of the pipeline, the elastic member 6 can provide sufficient elastic force to enable the inspection member 2 to move toward the vertical direction of the pipeline, so that the elastic member 6 is in a stressed state. At this time, the elastic member 6 in the stressed state can make the inspection part 21 on the inspection member 2 closely contact with the outer wall of the pipeline, thereby completing the inspection of the outer wall of the pipeline;

[0074] When inspecting the inner wall of the pipeline, the pressure plate 7 is removed from the fixing seat 1, and then the elastic member 6 and the detection member 2 are taken out of the guide member 4 in turn, and then the elastic member 6 is first sleeved on the outside of the guide member 4, and then the connecting member 5 of the detection member 2 is sleeved on the outside of the guide member 4 to abut against the elastic member 6, and finally the pressure plate 7 is fixed to the fixing seat 1. At this time, the detection member 2 is in the highest position of the groove 110, and the elastic member 6 can stably provide reverse elastic force to make the detection part 21 on the detection member 2 contact with the inner wall of the pipeline.
