Embodiment 1

[0031] Embodiment 1 The present invention is used for the electromagnetic method device of PCCP pipeline broken wire detection

[0032] see Figure 1-6, the present invention provides a technical solution: an electromagnetic method device for PCCP pipeline broken wire detection, which includes: a connecting shaft 3, and a moving device for moving the connecting shaft 3 is sleeved at both ends of the connecting shaft 3 , the mobile device includes a transmission mechanism 7 and three support mechanisms 6 located on the transmission mechanism 7, wherein the three support mechanisms 6 have the same shape and size, and the angle between two adjacent support mechanisms 6 is one hundred and two Ten degrees, an excitation coil 2 is arranged on the outer wall of the connecting shaft 3 between the two mobile devices, which is used to induce a sudden magnetic field distributed along the circumference of the cross-section of the PCCP pipe body 1, and the outer wall of the connecting shaf...

Embodiment 2

[0037] Embodiment 2: The present invention is used for the method for PCCP pipeline broken wire detection

[0038] A method for PCCP pipeline broken wire detection, comprising the following steps:

[0039] Step 1: According to the diameter of the PCCP pipeline body 1 on site, adjust the mobile device installed at both ends of the connecting shaft 3 to ensure that the mobile device can move smoothly inside the PCCP pipeline body 1. When adjusting, start the drive mechanism 75 The driving motor 752 on the top drives the driving gear 751 to rotate. Since the driving gear 751 is meshed with the gear ring 71, the gear ring 71 will rotate with the driving gear 751, and the gear ring 71 is meshed with the transmission gear column 73. Therefore, gear ring 71 can drive transmission gear column 73 to rotate, and when transmission gear column 73 rotates, under the effect of gear block 66, can drive long slat 61 to slide on transmission mechanism 7, thereby can support mechanism 6 The ex...

Abstract

The invention discloses an electromagnetic method device and method for PCCP wire breaking detection. The device comprises a connecting shaft, wherein two ends of the connecting shaft are sleeved with moving devices for moving the connecting shaft, and each moving device comprises a transmission mechanism and three supporting mechanisms arranged on the transmission mechanism. According to the invention, a connecting shaft provided with an excitation coil, a detection coil and a data collector can be stably supported in a PCCP body through a supporting mechanism and a transmission mechanism, and the connecting shaft can be conveniently moved in the PCCP body, so that the broken wire detection of the PCCP body is greatly facilitated; and the abrupt change magnetic field generated by the excitation coil and the effect of the PCCP body steel wire breaking generate influence on the signal amplitude received by the detection coil and the phase difference of the detection signal relative to the excitation current, so that the PCCP body steel wire breaking detection is realized.

Description

technical field [0001] The invention belongs to the related technical field of PCCP pipeline broken wire detection, and in particular relates to an electromagnetic method device and method for PCCP pipeline broken wire detection. Background technique [0002] Prestressed steel cylinder concrete pipe (PCCP for short) refers to a water delivery pipe made by winding a hoop prestressed steel wire on a high-strength concrete core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. It is a high-strength concrete tube core with a steel cylinder wound with prestressed steel wire, sprayed with a cement mortar protective layer, using a steel socket, welded together with the steel cylinder, the socket has grooves and an apron to form a sliding apron The flexible joint is a composite structure composed of steel plate, concrete, high-strength steel wire and cement mortar, and has the respective characteristics of steel and concrete. Among them, the lin...
