Referring to fig. 2, a magnetic ring 313 is embedded in the rotating column 31, the outer wall of the magnetic ring 313 is flush with the outer wall of the rotating column 31, the magnetic ring 313 is located between the baffle 12 and the driven gear 311, and a magnetic ring 122 attracted to the magnetic ring 313 is fixedly connected in the through hole 121. When the driven gear 311 is engaged with the driving gear 211, the magnetic ring 313 is located in the magnetic ring 122 and attracted to the magnetic ring 122, and at this time, the attraction force between the magnetic ring 313 and the magnetic ring 122 is greater than the elastic force of the second spring 123 acting on the ring plate 312. So that when organism 1 continues to move ahead motor 21 can drive leaf 22 and cutting piece 32 and rotate simultaneously, and after motor 21 reversal, cutting piece 32 receives the resistance of water and the elasticity of spring two 123 is greater than the suction of magnetic ring 313 and magnetic ring 122 for the elasticity of spring two 123 and the resistance of water drive rotation post 31 and slide outward towards organism 1, so that driven gear 311 and driving gear 211 break away from, realize that motor 21 only drives drive leaf 22, reduce the output, reduce the loss.
The embodiment of the application provides a drainage pipe detection device's implementation principle does: when the drainage pipes with different calibers are detected, the pressing roller 43 drives the telescopic column 42 to slide towards the machine body 1, so that the telescopic column 42 compresses the first spring 441, the distance between the roller 43 and the machine body 1 is reduced, the machine body 1 is placed into the drainage pipe after the size is reduced, the first spring 441 pushes the telescopic column 42 to extend, and the roller 43 is pushed against the inner wall of the drainage pipe. Then the starting motor 21 drives the driving blade 22 to rotate, so that the machine body 1 travels in the drainage pipeline, and the detection is carried out through the camera 11 at the front section of the machine body 1. Once meet the barrier after, the barrier acts on cutting piece 32 for driven gear 311 is meshed on driving gear 211, makes motor 21 drive vane 22 and also drives cutting piece 32 and rotate when rotating, realizes the cutting to the barrier, so that organism 1 walks in the drainage pipe and detects, thereby is convenient for detect the drainage pipe of different diameters size.
The embodiment of the application also discloses a drainage pipeline detection method.
Referring to fig. 2 and 3, the end of the body 1 having the camera 11 is first placed in the drain pipe, and then the two rollers 43 at the front end of the body 1 are pressed, so that the telescopic column 42 compresses the first spring 441, and the distance between the two rollers 43 at the front end and the body 1 is shortened, so as to place the front end of the body 1 in the drain pipe. Then press two gyro wheels 43 of organism 1 rear end again, drive flexible post 42 compression spring 441, shorten the distance between two gyro wheels 43 that are located the rear and the organism 1 to put into drainage pipe with whole organism 1 in, make gyro wheel 43 butt in drainage pipe inner wall all the time, be convenient for organism 1 places and detects in the drainage pipe of different pipe diameters size.
Then let in water drainage pipe in, starter motor 21 drives drive vane 22 in drainage pipe internal rotation, opens camera 11 simultaneously to detect drainage pipe's inner wall, make organism 1 shoot through camera 11 when walking in drainage pipe.
Until the machine body 1 meets the obstacle in the drainage pipeline, the obstacle prevents the trolley from continuing to move forward, and the motor 21 continues to drive the driving blade 22 to rotate, so that the cutting blade 32 and the rotating column 31 are abutted against the obstacle. The blocking object enables the cutting blade 32 and the rotating column 31 to slide towards the driving blade 22, so that the rotating column 31 slides towards the motor 21, the ring plate 312 compresses the second spring 123 until the driven gear 311 is meshed with the driving gear 211, the magnetic ring 313 slides into the magnetic ring 122 to be attracted, and the motor 21 drives the driving blade 22 to rotate and simultaneously drives the rotating column 31 to rotate. So as to drive the cutting blade 32 to cut the obstruction in the drainage pipeline, and the machine body 1 also continues to move forward while cutting, so as to clean the sediment of the drainage pipeline.
After the obstacle is cleaned, the motor 21 rotates reversely to drive the driving blade 22 to rotate reversely, so that the machine body 1 gradually retreats in the drain pipe. The resistance of water in the drainage pipeline acts on the cutting disc 32 when retreating to drive the cutting disc 32 to slide towards the direction of keeping away from the machine body 1, make the resistance of water and the elasticity of the second spring 123 be greater than the attraction of the magnetic ring 313 and the magnetic ring 122, and then make the rotation column 31 slide towards the direction of keeping away from the motor 21, in order to break away from the driven gear 311 from the driving gear 211, realize that the motor 21 only drives the drive vane 22 to rotate, save the energy consumption, improve the continuation of the journey, so that the machine body 1 can detect in the drainage pipeline for a long time.
The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
