[0002] Power conduit is a kind of cable conduit that meets the requirements of cable access channels of substations and undergrounding of overhead lines, and provides power channels for power supply of plots along the line. Power conduit is also known as cable pipe, power cable pipe, cement cable pipe, power conduit, etc. The outstanding features of power conduit are high strength and low friction resistance. Generally, power conduit is constructed simultaneously with road construction or municipal pipeline construction.

[0003] However, in the prior art, the existing power pipes generally need to be safety inspected using a flaw detector before they are officially used, so as to detect whether there are cracks on the surface of the power pipes. When the existing power pipes are inspected for cracks using a flaw detector, the power pipes are usually stationary, which makes it difficult to achieve all-round inspection of the entire circumferential direction of the power pipes, resulting in low detection accuracy. Utility Model Content

[0009] Compared with the prior art, the advantages and positive effects of the present invention are:

[0010] The utility model places the electric power pipe horizontally on the receiving arc plate, then contracts the No. 1 electric telescopic rod to lower the connecting frame as a whole, allowing the surface of the roller to contact the surface of the electric power pipe, and then drives the output shaft and the roller to rotate with the help of the No. 1 motor.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1

[0018] like Figure 1-3As shown, the utility model provides a technical solution: an electric pipe safety detection device, comprising a base bracket 1, both ends of the base bracket 1 are fixedly connected to a receiving arc plate 2, with the help of the base bracket 1 and the receiving arc plate 2, it is convenient to suspend the electric pipe and to rotate it later, the surface of the base bracket 1 is located at the side of the receiving arc plate 2 and is fixedly connected to an electric telescopic rod 4, and one end of the electric telescopic rod 4 is fixedly connected to a connecting frame 5, which controls the overall lifting and lowering of the connecting frame 5 through the extension and retraction of the electric telescopic rod 4, and in the process of placing the electric pipe on the receiving arc plate 2, the connecting frame 5 carries the roller 8 to rise as a whole, so as to avoid the electric pipe from easily colliding with the roller 8 in the process of being placed on the receiving arc plate 2, causing the roller 8 to hinder the placement of the electric pipe, a motor 6 is fixed to the surface of one side of the connecting frame 5, and the output end of the motor 6 is fixedly connected to the output shaft 7, the output shaft 7 It is connected to the connecting frame 5 through which it rotates, and a roller 8 is fixedly connected to the outer surface of the output shaft 7. When the electric pipe is placed on the receiving arc plate 2, the connecting frame 5 is lowered to make the roller 8 contact with the electric pipe. Then, with the help of the No. 1 motor 6, the output shaft 7 and the roller 8 are driven to rotate. When the roller 8 rotates, the friction between the roller and the electric pipe drives the electric pipe to rotate, so that the flaw detector 11 below it can easily perform all-round detection of the entire circumferential direction. A No. 2 electric telescopic rod 9 is provided on the surface of the middle section of the base bracket 1, and a fixed frame 10 is fixed to one end of the No. 2 electric telescopic rod 9. A flaw detector 11 is fixed on the surface of the fixed frame 10. The extension of the No. 2 electric telescopic rod 9 drives the fixed frame 10 and the flaw detector 11 to move upward as a whole, so that the probe on the flaw detector 11 can be in stable contact with the electric pipe placed on the receiving arc plate 2, thereby maintaining stable detection of the electric pipe by the flaw detector 11.

[0019] Example 2

[0020] like Figure 1-3As shown, a rotating short shaft 3 is rotatably embedded on the surface of the receiving arc plate 2, and the number of the rotating short shafts 3 is set to be several. With the assistance of the rotating short shaft 3, the resistance of the electric power pipe when rotating on the receiving arc plate 2 is reduced, making it easier for the electric power pipe to rotate on the receiving arc plate 2. A rubber anti-skid layer is fixedly installed on the outer surface of the roller 8. With the help of the rubber anti-skid layer, the friction force of the surface of the roller 8 is increased, thereby making it easier for the roller 8 to drive the rotation of the electric power pipe. One end of the No. 2 electric telescopic rod 9 is fixedly connected to a sliding block 12, and the sliding The block 12 is slidably connected to the base bracket 1. A screw rod 13 is threadedly connected to the sliding block 12, and the screw rod 13 is rotatably connected to the base bracket 1. A No. 2 motor 14 is fixedly connected to one side of the bottom end of the base bracket 1. The output end of the No. 2 motor 14 is fixedly connected to the screw rod 13. The screw rod 13 is driven to rotate by the No. 2 motor 14, so that the sliding block 12 moves linearly on one side of the base bracket 1. The movement of the sliding block 12 drives the movement of the No. 2 electric telescopic rod 9, the fixed frame 10 and the flaw detector 11, thereby expanding the detection range of the flaw detector 11 for the power pipe.

[0021] Working principle:

[0022] like Figure 1-3 As shown, when the utility model is in use, the user first places the electric pipe horizontally on the receiving arc plate 2, and then controls the No. 1 electric telescopic rod 4 to contract to make the connecting frame 5 drop as a whole. The drop of the connecting frame 5 drives the roller 8 to drop, so that the surface of the roller 8 contacts the surface of the electric pipe, and then extends the No. 2 electric telescopic rod 9 to drive the fixed frame 10 and the flaw detector 11 to move up, so that the probe on the flaw detector 11 is in stable contact with the surface of the electric pipe, and then turns on the flaw detector 11 to detect the electric pipe. In order to ensure that the flaw detector 11 performs all-round detection on the electric pipe and improve the detection accuracy, the No. 1 motor 6 is turned on at this time. The start of the No. 1 motor 6 drives the output shaft 7 and the roller 8 to rotate, and the rotation of the roller 8 drives the contact with it. The electric power tube rotates, and the rotating short shaft 3 will rotate along with it, so that the resistance to the rotation of the electric power tube is reduced, making it easier to rotate. When the electric power tube rotates, the flaw detector 11 can perform all-round detection on it in the entire circumferential direction, thereby improving the accuracy of its detection. When it is necessary to further expand the detection range of the flaw detector 11 on the electric power tube, the No. 2 motor 14 is started to drive the screw rod 13 to rotate. The rotation of the screw rod 13 drives the sliding block 12 to move in a straight line along the edge of the base bracket 1. The movement of the sliding block 12 drives the movement of the No. 2 electric telescopic rod 9, the fixed frame 10 and the flaw detector 11, thereby expanding the detection range of the flaw detector 11 on the electric power tube, so that the flaw detector 11 can perform more comprehensive detection on the electric power tube.
