[0023] (3) In the present invention, a retractable first telescopic rod is provided. In the detection preparation stage, the first telescopic rod is stretched through the detection range of the detection mechanism so that the bottom end of the detection mechanism and the bottom end of the moving mechanism are on the same horizontal line, so that the moving mechanism can be adjusted according to the inner diameter of the pipe, which is beneficial to the stability of the detection device during the movement and increases the application range of the moving mechanism.

[0024] (4) The present invention arranges two balancing devices on the moving mechanism, and the balancing device is mainly composed of a retractable second telescopic rod, a cross bar and a rotating wheel. By unfolding the second telescopic rod on both sides of the moving mechanism, the rotating wheel on the balancing device contacts the tube walls on both sides of the moving mechanism, thereby limiting the moving direction of the moving mechanism and preventing the moving mechanism from tilting to both sides, thereby further improving the stability and accuracy of the detection device.

[0046] A method for detecting internal blockage of a pipe, the method comprising the following steps:

[0047] S1. Take a pipe to be tested and adjust the detection mechanism 5 in the detection device according to the inner diameter of the pipe to be tested;

[0048] S2. Place the adjusted detection device inside the pipe to be detected, and start the detection device to move it inside the pipe to be detected to obtain blockage information inside the pipe to be detected;

[0049] S3. When the detection device passes through the pipe to be detected, or the detection device cannot move in the pipe to be detected, the detection is completed.

[0050] Based on the above disclosed detection device and detection method, the working principle and use process of the present invention are explained in detail as follows:

[0051] SS1. Take a pipe to be tested, and adjust the mounting rod 55 according to the inner diameter of the pipe to be tested, so that the mounting rod 55 contracts or stretches to change the expansion range of the sensing strip 52, so that the sensing ball 51 on the sensing strip 52 contacts the inner wall of the pipe; wherein, the specific method of adjusting the mounting rod 55 is as follows: after the mounting rod 55 is pulled out from the support rod 41 according to the demand, the clamping ring 42 is manually held and moved toward the clamping block 46, so that the part of the outer side of the clamping block 46 protruding from the notch 47 is squeezed by the clamping ring 42, As a result, the block 46 is retracted into the notch 47 and squeezes the mounting rod 55 below the notch 47. The mounting rod 55 is fixed inside the support rod 41 through the friction between the block 46 and the mounting rod 55, thereby realizing the fixing operation of the overall detection mechanism 5. After completing the above operation, the balancing device 6 on both sides of the mechanical box 9 in the mobile mechanism 1 is unfolded, and the cross bar 63 is manually pulled out to extend the second telescopic rod 62, so that the wheels 61 on the protrusions 64 on both sides contact the tube walls on both sides of the mechanical box 9 respectively.

[0052] SS2. Place the adjusted detection device inside the pipe to be tested, start the mobile mechanism 1 to move inside the pipe for testing, and the mobile mechanism 1 always keeps moving in a straight line due to the obstruction of the two rotating wheels 61 on both sides;

[0053] SS3. When the detection device passes through the pipe to be detected, the obstruction adheres to the inner wall of the pipe, and each sensing ball 51 on the detection mechanism 5 contacts the inner wall of the pipe in all directions, and is blocked and squeezed by the obstruction, so that the corresponding sensing ball 51 changes its posture, thereby sounding an alarm;

[0054] Above:

[0055] When the obstruction exceeds the radius of the pipe, the sensing head 56 will first contact the obstruction, thereby issuing a corresponding alarm of the sensing head 56;

[0056] When the obstruction is smaller than the radius of the pipe, the obstruction contacts one or more of the sensing strips 52. Since the moving mechanism is still moving, the obstruction is squeezed with the sensing strips 52 in contact, so that the sensing strips 52 sense the squeezing and issue a corresponding alarm.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
