An underground drainage pipe detection device

Abstract

The present invention discloses an underground drainage pipeline detection device, which includes a detection rod, a handle, a button, a power supply wire, a telescopic arm, a footrest, a periscope, a wire clamping seat and a stabilizing mechanism. In the present invention, a stabilizing mechanism is arranged in the middle of the outer surface of the detection rod. By pressing the button to start the electric push rod, the electric push rod pushes the connecting sleeve to move upward along the surface of the detection rod, so that the support rod contacts the inner wall of the well through the cushion seat at the end of the sliding rod, thereby enabling the support rod to provide stable support for the detection rod and preventing it from shaking easily during the detection process to achieve a good shooting effect. An automatic extension mechanism is arranged inside the top of the support rod. During the unfolding process of the support rod, the connecting component drives the bevel gear to rotate, and then the screw rod rotates synchronously with the bevel gear, so that the screw rod pushes the sliding rod out of the sliding cavity to achieve the effect of extending the force arm of the support rod to ensure that the cushion seat can be in close contact with the inner wall of the well and can adapt to wells of different sizes.

[0028] The present invention provides an underground drainage pipe detection device through improvement, and its working principle is as follows;

[0029] First, before use, first connect the power wire 4 to an external power source to provide power for the detection device. Then, buckle the data cable connecting the periscope 7 to the ground device into the wire clamping seat 8 for fixation to prevent the data cable from being hooked by foreign objects;

[0030] Second, during use, hold the handle 2 and put the detection rod 1 into the well. Then, control the lifting of the telescopic arm 5 through the button 3 to put the periscope 7 into the pipe. At the same time, the foot pad 6 touches the bottom of the well to provide a stable support for the telescopic arm 5. Then, the inner view of the pipe can be photographed through the periscope 7 to detect whether there are cracks;

[0031] Third, after the detection rod 1 is placed stably, start the electric push rod 97 through the button 3 to make the electric push rod 97 push the connecting sleeve 95 to move upward along the surface of the detection rod 1. At the same time, the connecting sleeve 95 pushes the support rod 92 outwards through the transmission rod 96, so that the support rod 92 contacts the inner wall of the well through the cushion seat 941 at the end of the sliding rod 94, so that the support rod 92 provides a stable support for the detection rod 1 and is not easy to shake during the detection process to achieve a good shooting effect;

[0032] Fourth, during the expansion process of the support rod 92, the connection assembly 91 drives the bevel gear 981 to rotate, and then the screw 982 rotates synchronously with the bevel gear 981, so that the screw 982 pushes the sliding rod 94 out of the sliding cavity 93 to achieve the effect of extending the force arm of the support rod 92 to ensure that the cushion seat 941 can be in close contact with the inner wall of the well and can adapt to well channels of different sizes.

[0033] The present invention provides an underground drainage pipeline detection device through improvement. By arranging a stabilizing mechanism 9 in the middle of the outer surface of the detection rod 1, the electric push rod 97 is started by the button 3, so that the electric push rod 97 pushes the connecting sleeve 95 to move upward along the surface of the detection rod 1, and the support rod 92 contacts the inner wall of the well through the cushion seat 941 at the end of the sliding rod 94, so that the support rod 92 provides a stable support for the detection rod 1 and is not prone to shaking during the detection process, so as to achieve a good shooting effect. By arranging an automatic extension mechanism 98 inside the top of the support rod 92, during the unfolding process of the support rod 92, the connecting component 91 drives the bevel gear 981 to rotate, and then the screw rod 982 rotates synchronously with the bevel gear 981, so that the screw rod 982 pushes the sliding rod 94 out of the sliding cavity 93, so as to achieve the effect of extending the force arm of the support rod 92 and ensure that the cushion seat 941 can be in close contact with the inner wall of the well and can adapt to wells of different sizes.
