Through adopting above-mentioned technical scheme, observation device is comparatively fragile and accurate electron device usually, and the protective shaft portion holds observation device in order to regard as observation device's protective housing for when surveying the main part and advancing in the pipeline, observation device is difficult to be destroyed by the foreign object. Because the length sum of the swing rod and the protection shaft part in the axial direction is greater than the width of the pipeline, and the limit blocks are arranged on two sides of the swing rod to limit the swing amplitude of the swing rod, so that the detection main body cannot be overturned when being pushed to the deep part of the pipeline, and can be smoothly pushed to the deep part of the pipeline by the extension device. Because the length of the swing rod in the axial direction and the length of the protection shaft part in the axial direction are both smaller than the width of the pipeline, when the detection main body meets the pipeline turning, the swing rod can deflect relative to the protection shaft part, so that the detection main body is integrally twisted to pass through the pipeline turning part.

By adopting the technical scheme, the swing rod is pulled by the elastic piece, so that the swing rod is coaxial with the protective shaft part when the swing rod is not subjected to lateral force, and the detection main body can smoothly advance under the pushing of the extension device in a straight pipeline. When the protective shaft part meets an obstacle, the protective shaft part has a certain moving space in the radial direction of the pipeline, so the protective shaft part is laterally deviated under the pushing of the extension device, and a lateral force is generated on the protective shaft part. The lateral force enables the protection shaft part to press the elastic part, and the protection shaft part swings in the direction far away from the swing rod, so that the protection shaft part bypasses the barrier. When the swing rod passes by the barrier, the elastic piece is deformed and restored, and the swing rod tends to be coaxial with the protective shaft part again under the action of the elastic piece.

Further setting: the inside of protection axial region is provided with the cavity that is used for holding camera and searchlight, the electric wire of camera and searchlight passes through cavity, pendulum rod and hose in order to link to each other with external receiving arrangement.

Through adopting above-mentioned technical scheme, inside the searchlight can illuminate the pipeline, the camera can observe the pipeline internal conditions and transmit the outside to the influence passing signal line.

Further setting: and one end of the protection shaft part, which is far away from the swing rod, is provided with an outwardly convex cambered surface.

Through adopting above-mentioned technical scheme, because the condition in the pipeline is comparatively complicated, often can have various barriers, the outside convex cambered surface setting of protection axial region head makes the protection axial region can slide to the side when the butt is in the barrier to in order to walk around the barrier.

Further setting: the protection shaft part is made of acrylic material.

In addition, the light transmittance of the acrylic plate is more than 93%, which is far higher than that of glass by 70%, and the protective shaft part made of acrylic material can make the observation effect of the observation mechanism better.

Further setting: the elastic piece is a pressure spring.

By adopting the technical scheme, the pressure spring is an industrial standard component, is convenient to obtain and easy to replace, and can keep elasticity for a long time.

To sum up, the utility model discloses following beneficial effect has:

1. The detection main body is not easy to twist when advancing in the pipeline and can turn along the trend of the pipeline;
