A nonexcavation type pipe inspection device is provided to inspect a pipe easily by using a camera, to protect a fragile component such as a camera from high pressure sewage and impurities contained in the sewage by using an air packer and a streamline shaped cap and to search for the location of a manhole easily by using a frequency transmitter. The nonexcavation type pipe inspection device contains: a main body(110) formed longitudinally to support a camera, an air packer, a streamlined cap and a support leg and provided with a spiral coupled with a spiral formed on the inside of a joint of a streamlined cap; a camera(120) installed to the front of the main body to take a photograph of an internal wall of a front pipe and moving forward and backward by a support composed of a hydraulic cylinder; an air packer(130) installed to expand and contract from the main body and connected with an air hose(135) to get supplied with air from an air pump; a wire cap(140) installed to the rear of the main body in a streamline to reduce pressure or resistance by the velocity of flowing sewage; a support leg(150) installed to expand and contract horizontally from the front and rear of the main body and composed of a hydraulic cylinder for expansion and contraction; driving wheels(160) installed to each end of the support leg to move the whole inspection device along the internal wall of the pipe; and a frequency transmitter installed to the main body to transmit frequency and to get the location, depth and direction of the inspection device above the ground. |
