DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Embodiment 1:

[0025] Please refer to Figures 1-6 A smart city underground pipeline fault detection device, including device support part 1, device support part 1 top rotary mounting device rotating seat 3, device rotating seat 3 on installing fault detection assembly 4, the bottom of device support part 1 periphery is connected with support rod 5, and support rod 5 includes connecting head 51, connecting head 51 is connected with device support part 1, the bottom of connecting head 51 is fixedly connected with rod body 52, the outer surface of rod body 52 is provided with helical thread, the outer side of rod body 52 is provided with extension rod 2, and extension rod 2 is hollow tubular, the inner wall of extension rod 2 is provided with helical groove, extension rod 2 is helically connected with rod body 52 by helical groove, the bottom of extension rod 2 is provided with through hole 23, the bottom end of extension rod 2 is fixedly installed with rotating head 22, and rotating head 22 is rotatably connected with support pad 7.

[0026] Specifically, the support rod 5 in the device adopts an adjustable structure. The support rod 5 is screw-connected with the screw groove in the inner wall of the extension rod 2 through the screw thread on the outer surface of the rod body 52, so that the extension rod 2 can be rotated and lifted relative to the rod body 52. When the detection device is placed on uneven ground, the operator can change the extension length of the extension rod 2 by rotating the extension rod 2, so as to compensate for the height difference of different positions on the ground. For example, if the ground corresponding to one corner of the device is lower, the extension rod 2 at this position can be elongated, so that the device support part 1 remains horizontal. Since the device rotating seat 3 is installed above the device support part 1 and can rotate, when the device support part 1 is horizontal, the fault detection assembly 4 installed on the device rotating seat 3 can also remain in a horizontal state. The problem of sensor inclination of the detection device is avoided, and the relative angle between the detection device and the underground pipeline remains stable, which is beneficial to the normal reception and analysis of the detection signal.

[0027] The rotating head 22 at the bottom of the extension rod 2 is rotationally connected with the support pad 7. After the length of the extension rod 2 is adjusted to make the device horizontal, the support pad 7 can better fit the shape of the ground. Moreover, the rotating head 22 can automatically adjust the angle of the support pad 7 according to the slight ups and downs or inclination of the ground, further enhancing the stability and flatness of the device placed.

[0028] By adjusting the length of the extension rod 2 to make the device support part 1 horizontal, and by means of the rotating head 22 and the support pad 7 being well fitted with the ground, the gravity distribution of the device is more reasonable, and the overall stability is significantly improved. During the detection process, the device shaking caused by external factors can be effectively reduced, and the detection signal of high-precision detection instruments (such as cable fault detection instruments, multifunctional flaw detectors, etc.) can be prevented from fluctuating due to shaking, so as to ensure that stable and reliable detection data is obtained.

[0029] Embodiment 2

[0030] To limit the extension rod 2, please refer to Figures 1-6 On the basis of embodiment 1, the limit ring 6 is fixedly installed on the extension rod 2. The middle of the limit ring 6 is fixedly provided with a moving pipe 61, the inside of the moving pipe 61 is in communication with the inner cavity of the extension rod 2, the inside of the moving pipe 61 is provided with a pull rod 64, and the two ends of the pull rod 64 are respectively connected with a pull handle 641 and a limit block 642.

[0031] The inside of the moving pipe 61 is connected with a spring 65, the spring 65 is connected with a push plate 63, and the push plate 63 is slidingly installed on the pull rod 64.

[0032] Grooves 631 are formed in the two sides of the push plate 63, and limit strips 62 are fixedly installed on the inner walls of the moving pipe 61 and matched with the grooves 631.

[0033] The limiting block 642 passes through the side wall of the extension rod 2 and is matched with the limiting groove 53, and the limiting groove 53 is arranged on the outer surface of the rod body 52 in parallel to the central axis of the rod body 52;

[0034] The observation hole 21 is arranged on the extension rod 2.

[0035] Specifically, when the length of the extension rod 2 needs to be adjusted, the pull rod 64 is pulled to drive the limiting block 642 to move. The limiting block 642 connected to one end of the pull rod 64 moves in the moving pipe 61, at this time, the push plate 63 is driven by the limiting block 642 to slide in the moving pipe 61, and the spring 65 is compressed to generate elastic deformation. The slot 631 on both sides of the push plate 63 slides along the limiting strip 62 fixedly arranged on the inner wall of the moving pipe 61, and plays a guiding and limiting role. At the same time, when the limiting block 642 enters the moving pipe 61, the rotation of the pull handle 641 controls the rotation of the limiting block 642, so that the limiting block 642 can be clamped in the moving pipe 61, and the limiting strip 62 can avoid the deflection of the push plate 63 caused by the rotation of the limiting block 642. At this time, the limiting block 642 is removed from the limiting groove 53 to facilitate the rotation of the extension rod 2;

[0036] When the extension rod 2 is rotated to the appropriate position and reaches the desired length of extension or shortening, the pull handle 641 is rotated in the opposite direction, and the spring 65 stores elastic potential energy due to being compressed before, which is released at this time to push the push plate 63, and then drive the limiting block 642 to move in the opposite direction and pass through the side wall of the extension rod 2 to be inserted into the limiting groove 53 arranged on the outer surface of the rod body 52 in parallel to the central axis, so that the limiting block 642 cooperates with the limiting groove 53 to limit the rotation and axial movement of the extension rod 2 relative to the rod body 52, thereby realizing the position fixation of the extension rod 2 and achieving the purpose of limiting the extension rod 2;

[0037] The observation hole 21 is arranged on the extension rod 2, and the position of the limiting groove 53 can be observed through the observation hole 21 during operation, so that the limiting block 642 and the limiting groove 53 can be accurately aligned;

[0038] Through the cooperation of the limiting block 642 and the limiting groove 53, the position of the extension rod 2 can be firmly locked, so that the extension rod 2 will not rotate or move axially accidentally during the use of the detection device due to external force and the like, which helps to maintain the height stability of the entire device support part 1, and then ensures that the device rotating seat 3 and the fault detection assembly 4 arranged thereon are always in a stable state, thereby ensuring the accuracy of the detection work, and the relative position and angle relationship between the detection device and the underground pipeline will not be affected by the accidental change of the extension rod 2.

[0039] Working principle: the detection personnel can judge whether the device is horizontal and the height difference of the ground corresponding to each support rod 5 by observing the fault detection component 4 installed on the device, and for the extension rod 2 on the support rod 5 that needs to be adjusted, the detection personnel holds the pull handle 641 and pulls it outward to drive the pull rod 64 to move.

[0040] One hand holds the rod body 52, and the other hand holds the extension rod 2, and by rotating the extension rod 2, the extension rod 2 is rotated and lifted relative to the rod body 52 by utilizing the screw connection relationship between the spiral threads on the outer surface of the rod body 52 and the spiral grooves on the inner wall of the extension rod 2, so as to change the extension length of the extension rod 2, when the extension rod 2 is rotated to the appropriate position and reaches the desired extension or shortening length, the pull handle 641 is reversely rotated, the spring 65 loses the external force limitation and restores to the original state, the push plate 63 is pushed, and then the limiting block 642 is reversely moved and passes through the side wall of the extension rod 2 and is inserted into the limiting groove 53 arranged on the outer surface of the rod body 52 and parallel to the central axis, so that the limiting block 642 cooperates with the limiting groove 53 to limit the rotation and axial movement of the extension rod 2 relative to the rod body 52, thereby firmly locking the position of the extension rod 2, and the position fixation of the extension rod 2 is realized.
