[0010] Preferably, the extension portion is provided with a spline shaft that can rotate freely in the vertical direction. The spline shaft rotates on the extension portion and is coaxially fixed with a driving bevel gear. The driving bevel gear meshes with a driven bevel gear. The driven bevel gear rotates on the extension portion and is coaxially fixed with the drive wheel.

[0011] Preferably, the threaded rod is threadedly connected to an internal threaded cylinder, the outer ring of the internal threaded cylinder is fitted with a shaft boss that moves synchronously with it, the shaft boss has a receiving groove inside, and a rectangular plate is slidably connected in the receiving groove.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 8 The present invention provides a technical solution: a portable data acquisition device, including an outer shell 1 for accommodating and protecting a sensor module and a handle 2 provided thereon, wherein the outer shell 1 is provided with a spreading mechanism for driving itself to move inside a pipe;

[0032] The laying mechanism includes a set of positioning end seats 4 respectively disposed on both sides of the outer shell 1. A transverse shaft 21 driven by a motor and freely rotating in the vertical direction is provided between the two sets of positioning end seats 4. The transverse shaft 21 is fixedly rotated on the positioning end seats 4. A swing seat 5 is fixedly rotated on both sets of positioning end seats 4. The swing seat 5 is provided with a drive wheel 20 for contacting the inner wall of the pipe. The swing seat 5 is provided with an extension shaft assembly that drives the drive wheel 20 to move horizontally and rotates freely after it is in close contact with the inner wall of the pipe.

[0033] The outer shell 1 has a side cavity 3 for accommodating the extension shaft assembly in the deflection direction of the swing seat 5. The swing seat 5 is threaded with multiple sets of locking bolts, and the positioning end seat 4 has threaded holes that cooperate with the locking bolts.

[0034] like Figure 1 and Figure 2 As shown, when the data acquisition device is in its normal storage state, the tilting seat 5 is deflected to drive the tilting seat 5 and the extension shaft assembly set on it to fold into the corresponding side cavity 3. The multiple sets of locking bolts on the tilting seat 5 are then turned to drive it into the corresponding threaded holes, thereby locking the tilting seat 5 to prevent arbitrary deflection. Therefore, by opening the side cavity 3 on the outer shell 1, the extension shaft assembly can be folded and stored during normal storage to reduce its space size and facilitate carrying and transportation.

[0035] Meanwhile, when using the data acquisition device, the swing seat 5 is driven to extend out of the side cavity 3 and locked by the locking bolt. The drive wheel 20 is driven by the extension shaft assembly to gradually move away from the outer shell 1 until the drive wheel 20 is tightly attached to the inside of the pipe. After the drive wheel 20 is tightly attached to the inside of the pipe, the drive wheel 20 can rotate freely in the horizontal direction. Furthermore, by setting two sets of extension shaft assemblies, the outer shell 1 can be suspended and supported inside the pipe by both sets of drive wheels 20 being tightly attached to the inner wall of the pipe, so as to avoid the presence of the outer shell 1 from interfering with the cables and other components inside the pipe.

[0036] Meanwhile, in actual use, multiple sets of symmetrical extension shaft assemblies are set on the outer shell 1, and the drive wheels 20 on both sides of the outer shell 1 rotate in opposite directions. Thus, when the drive wheels 20 rotate, they can cause the outer shell 1 and the sensor modules set on it to move along the laying direction of the pipeline, so as to realize the real-time acquisition of data inside the pipeline.

[0037] In one preferred embodiment, the extension shaft assembly includes a threaded rod 6 that rotates on a fixed axis on a sway seat 5. The threaded rod 6 rotates freely in the vertical direction and is connected to the transverse shaft 21. The positioning end seat 4 is provided with a universal joint for the transmission of both the threaded rod 6 and the transverse shaft 21.

[0038] The swing seat 5 is provided with a shaft boss 8 that moves freely along the laying direction of the threaded rod 6. The shaft boss 8 is provided with an outer clamping plate 13. The end of the outer clamping plate 13 away from the swing seat 5 includes an integrally formed bending extension 131. The drive wheel 20 rotates on the bending extension 131 on a fixed axis.

[0039] like Figure 1 and Figure 2 As shown, when the operating state of the data acquisition device is changed, i.e. when the swing seat 5 is in the extended or retracted state, the swing seat 5 is rotated on the positioning end seat 4 by moving it, so as to change the orientation of the extension shaft assembly. The transverse shaft 21 is driven by a motor to rotate freely, and the transverse shaft 21 is connected to the threaded rod 6 through a universal joint. Therefore, when the swing seat 5 is deflected relative to the positioning end seat 4, under the transmission action of the universal joint, the transverse shaft 21 can still drive the threaded rod 6 to rotate on the swing seat 5 when it rotates, and thus can still promote the operation of the extension shaft assembly.

[0040] Furthermore, the extension portion 131 is provided with a spline shaft 17 that can rotate freely in the vertical direction. The spline shaft 17 is fixedly rotated on the extension portion 131 and coaxially fixed with a driving bevel gear 18. The driving bevel gear 18 is meshed with a driven bevel gear 19. The driven bevel gear 19 is fixedly rotated on the extension portion 131 and coaxially fixed with the drive wheel 20.

[0041] The threaded rod 6 is threadedly connected to an internal threaded cylinder 7. The outer ring of the internal threaded cylinder 7 is fitted with a shaft boss 8 that moves synchronously with it. The shaft boss 8 has a receiving groove inside, and a rectangular plate 9 is slidably connected in the receiving groove. The internal threaded cylinder 7 has a locking groove 10 that cooperates with the rectangular plate 9. A relief spring 11 is provided in the receiving groove, and the two ends of the relief spring 11 are fixedly connected to the rectangular plate 9 and the shaft boss 8 respectively.

[0042] The swing seat 5 is fixedly connected with a guide post 22 that is parallel to the threaded rod 6. The shaft boss 8 is provided with a round hole for the guide post 22 to slide through. The shaft boss 8 is provided with a locking component to release the rectangular plate 9 from the restriction of the internal threaded cylinder 7.

[0043] The locking assembly includes a groove on the shaft protrusion 8 for sliding connection of the outer clamping plate 13. A locating pin 12 is fixedly connected to one end of the rectangular plate 9 facing the outer clamping plate 13. A V-shaped groove 23 is provided on the outer clamping plate 13 for sliding connection of the locating pin 12. In the initial state, the rectangular plate 9 is in the locking groove 10, and the locating pin 12 is located in the middle of the V-shaped groove 23.

[0044] like Figure 2 - Figure 8 As shown, in the initial state, under the action of the elastic potential energy of the relief spring 11, the rectangular plate 9 is in the locking groove 10. Then, when the threaded rod 6 rotates freely under the transmission action of the transverse shaft 21, the shaft boss 8 is restricted by the guide post 22 and can only move horizontally along the laying direction of the guide post 22. The internal threaded cylinder 7 is restricted by the rectangular plate 9 and cannot rotate on the shaft boss 8. Then, when the threaded rod 6 rotates, it can drive the shaft boss 8 and the internal threaded cylinder 7 to move synchronously in the horizontal direction until the drive wheel 20 is in close contact with the inner wall of the pipe.

[0045] Meanwhile, when the drive wheel 20 is pressed against the pipe wall, the drive wheel 20 and the outer clamping plate 13 cannot continue to move horizontally due to the obstruction of the pipe wall. As a result, when the threaded rod 6 rotates, the shaft boss 8 and the internal threaded cylinder 7 can continue to move a small distance in the horizontal direction, which causes the co-position pin 12 to slide on the V-shaped slide groove 23 and drive the rectangular plate 9 to slide in the receiving groove, so as to cause the rectangular plate 9 to disengage from the locking groove 10. At this time, the internal threaded cylinder 7 will no longer be restricted by the rectangular plate 9. As a result, when the threaded rod 6 rotates later, the internal threaded cylinder 7 will rotate with the threaded rod 6, and the horizontal position of the shaft boss 8, the outer clamping plate 13 and the drive wheel 20 will no longer change. As a result, the drive wheel 20 adapts to the inner diameter of the pipe, so that the drive wheel 20 will no longer continue to move horizontally after being pressed against the pipe wall.

[0046] It should be noted that in actual use, when the rectangular plate 9 is disengaged from the locking groove 10, the relief spring 11 undergoes compression deformation. At this time, the relief spring 11 tends to drive the rectangular plate 9 to move towards the locking groove 10 side when compressed. At the same time, the corresponding pin 12 fixed on the rectangular plate 9 is slidably connected to the outer clamping plate 13 through the V-shaped slide groove 23. Therefore, the outer clamping plate 13 tends to move towards the pipe wall side. However, it cannot continue to move horizontally due to the obstruction of the pipe. Thus, when the relief spring 11 undergoes compression deformation, it can drive the driving wheel 20 to have a certain resistance force against the pipe wall, thereby increasing the friction between the driving wheel 20 and the pipe wall to ensure the stability of the outer shell 1 when moving along the pipe laying direction.

[0047] Based on the embodiment of the extension shaft assembly, the outer ring of the threaded rod 6 is fitted with an end sleeve 14, the end sleeve 14 is coaxially fixed on the inner threaded cylinder 7, the end sleeve 14 is fixedly fitted with a drive gear 15, the drive gear 15 is meshed with a driven gear 16, and the driven gear 16 is slidably fitted on the spline shaft 17.

[0048] Two sets of limiting plates are fixedly connected to the shaft protrusion 8, and the driven gear 16 is located between the two sets of limiting plates and slides in contact with the limiting plates.

[0049] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, when the drive wheel 20 comes into contact with the pipe wall, the rectangular plate 9 disengages from the locking groove 10 as the threaded rod 6 rotates. Subsequently, the internal threaded cylinder 7 can rotate synchronously with the threaded rod 6. When the internal threaded cylinder 7 rotates, it can drive the drive gear 15 to rotate through the end cylinder 14 fixed coaxially with it. The drive gear 15 is meshed with the driven gear 16, and the driven gear 16 is slidably sleeved on the spline shaft 17. This can cause the spline shaft 17 and the drive bevel gear 18 at its end to rotate. The drive wheel 20 can be driven to rotate in the horizontal direction through the driven bevel gear 19 meshing with the drive bevel gear 18, so that the outer shell 1 can move inside the pipe.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
