[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention enables the drainage pipe inspection device to move smoothly through the circle block, and the support block and the monitoring head on the support block are rotated through the rotation of the lifting mechanism, which is beneficial to adjust the direction of the monitoring head according to the location of the drainage pipe to be inspected, and is beneficial to the inspection of various points of the drainage pipe. The direction of the monitoring head is adjusted through the rotation of the connecting mechanism, thereby expanding the inspection surface of the monitoring head for drainage pipes at different locations.

[0019] 2. The present invention rotates the bearing tray via a motor, and the rotation of the bearing tray causes the vertical cylinder and the lead screw, the supporting block and the monitoring head in the vertical cylinder to rotate accordingly, thereby expanding the direction adjustment surface of the monitoring head. The lead screw is threadedly connected in the vertical cylinder. When the supporting block is in a free state, the vertical cylinder rotates to cause the lead screw and the supporting block in the vertical cylinder to rotate together. When the supporting block is in a non-free state, for example, when the supporting block is fixedly connected to the supporting platform, the rotation of the vertical cylinder does not cause the lead screw and the supporting block in the vertical cylinder to rotate together. Since the lead screw is threadedly connected in the vertical cylinder, the lead screw is displaced upward or downward in the vertical cylinder, which is beneficial to adjust the vertical position of the supporting block and the monitoring head.

[0020] 3. The present invention rotates the connecting mechanism through the transmission mechanism, and the hydraulic cylinder expands. The sticking block and the connecting block are pressed against each other, and the connecting block is pressed to rotate. The connecting mechanism rotates along with the connecting block, and the monitoring head rotates along with the connecting block, and the direction of the monitoring head is adjusted to allow the monitoring head to inspect the drainage pipe that is biased to the bottom. The hydraulic cylinder becomes shorter, and the sticking block and the connecting block at the corresponding position are pressed against each other, so that the connecting block rotates in the opposite direction. The connecting mechanism rotates in the opposite direction along with the connecting block, and the monitoring head rotates in the opposite direction along with the connecting block, and the direction of the monitoring head is adjusted to allow the monitoring head to inspect the drainage pipe that is biased to the top.

[0021] 4. When the monitoring head faces forward, the block on the hydraulic cylinder and the connecting block are close to each other, which is conducive to suppressing the connecting mechanism and the monitoring head from rotating to the bottom. The interval between the two ring pieces on the connecting rod is the longest, and the interval between the linkage mechanisms is the longest. The lower end of the vertical block is closer to the outside of the rotating groove, and the vertical block 2 is located outside the through hole. The horizontal bar on the second ring piece and the maximum point of the protrusion on the first ring piece are close to each other. The first ring piece here is the lowest. The spiral beryllium copper wire between the second ring piece and the ring piece stores power, and the connecting mechanism is maintained through the spiral beryllium copper wire and the horizontal bar. The mechanism and the monitoring head face forward, and the motor rotates the bearing tray, the supporting block and the monitoring head on the supporting block rotate, the direction of the monitoring head is adjusted, the linkage mechanism rotates in the rotating groove, the hydraulic cylinder becomes shorter, the corresponding sticking block and the connecting block are pressed against each other, the connecting block rotates in the opposite direction, the connecting mechanism rotates in the opposite direction with the connecting block, the monitoring head rotates in the opposite direction with the connecting block, the direction of the monitoring head is adjusted, and the monitoring head is made to check the drainage pipe that is biased to the top. When the connecting rod rotates in the opposite direction, the connecting rod rotates to make the ring piece 2 rotate accordingly, and the ring The horizontal bar on the second piece rotates in the opposite direction of the circle block one, and the horizontal bar and the circle block one are gradually lifted, so that the circle piece two is pushed closer to the circle piece one, and the spiral beryllium copper wire between the circle piece two and the circle piece is tightened again. At this stage, the vertical block in the circle channel on the circle piece two approaches, and the linkage mechanism approaches through the vertical block, and the vertical block two approaches the center point of the supporting block along the through hole, and the vertical block one approaches the inside of the rotating groove. When the monitoring head is facing the top, the circle pieces two at the two ends of the connecting rod are at the shortest distance from each other through the horizontal bar and the circle block one, and the vertical block one passes through the circle piece two. The vertical block is close to the inside of the rotating groove, and protrusions are installed in the rotating groove and on the lower end of the vertical block. The protrusions on the rotating groove and the vertical block are linked to each other, so that the vertical block no longer rotates along the rotating groove, and the supporting block, the rotating mechanism, the monitoring head and the lead screw no longer rotate. Through the motor, the supporting block is in a non-free state here, and the rotation of the vertical cylinder does not cause the lead screw and the supporting block in the vertical cylinder to rotate together. Because the lead screw is threadedly connected in the vertical cylinder, the lead screw is displaced toward the top in the vertical cylinder to adjust the vertical position of the supporting block and the monitoring head, which is beneficial for checking the drainage pipe.

[0034] The drainage pipe inspection device moves smoothly through the circle block three 215, and the support block 214 and the monitoring head 411 on the support block 214 rotate through the rotation of the lifting mechanism 213, which is beneficial to adjust the direction of the monitoring head 411 according to the location of the drainage pipe to be inspected, and is beneficial to the inspection of various points of the drainage pipe. The direction of the monitoring head 411 is adjusted through the rotation of the connecting mechanism 312, thereby expanding the inspection surface of the monitoring head 411 for drainage pipes at different locations.

[0035] A motor is installed in the supporting platform 212, and the motor is connected to the lifting mechanism 213. The lifting mechanism 213 is rotated by the motor, which is conducive to rotating the supporting block 214 and the monitoring head 411 on the supporting block 214, and adjusting the direction of the monitoring head 411.

[0045] When the monitoring head 411 faces straight ahead, the sticking block 3136 on the hydraulic cylinder 3135 and the connecting block 3126 are in contact with each other, which helps to prevent the connecting mechanism 312 and the monitoring head 411 from rotating to the bottom. The interval between the two ends of the ring piece 2 3127 on the connecting rod 3125 is the longest, and the interval between the linkage mechanisms 511 is the longest. The lower end of the vertical block 1 512 is closer to the outside of the rotating groove 1014, and the vertical block 2 513 is on the outside of the through hole 2147. The horizontal bar 31273 on the ring piece 2 3127 and the protrusion on the ring block 1 2146 The maximum point is close together, where the circle piece 1 2146 is the lowest, and the spiral beryllium copper wire 31254 between the circle piece 2 3127 and the circle piece 1 31252 stores power.

Through the motor, the supporting block 214 is in a non-free state. The rotation of the vertical cylinder 2136 does not cause the lead screw 2137 and the supporting block 214 in the vertical cylinder 2136 to rotate together. Because the lead screw 2137 is threaded in the vertical cylinder 2136, the lead screw 2137 is displaced toward the top in the vertical cylinder 2136 to adjust the vertical position of the supporting block 214 and the monitoring head 411, which is beneficial to the inspection of the drainage pipe.
