[0002] Pipeline CCTV detection refers to an endoscopic camera detection system, which can also be understood as a municipal pipeline CCTV detection robot, which is composed of a controller, a lifting platform, a camera, a crawler and the like. The crawler has four wheels and looks like a large-scale toy remote control car. It can cross obstacles, freely move in the drainage pipe and timely transmit information in the pipe to the operation platform outside the well, and record the pipeline condition in all directions. CCTV pipeline detection can not only detect the blockage inside the pipeline, but also detect the pipeline material, pipe diameter, water leakage and damage.

At this time, the CCTV detection equipment needs to be driven in water. The deeper the equipment goes into the pipeline, the greater the pressure the equipment as a whole will bear. Therefore, the sealing structure of the equipment needs to be strengthened and reinforced to prevent water from seeping into the equipment and damaging the equipment under the action of pressure.

[0029] The effect achieved by the entire embodiment 1 is as follows: the rotating part 3 is placed inside the outer shell 1, so that the hollow rod 31 is connected to the motor 6 through gear transmission. Then, the annular piece 27 is placed inside the mounting groove 22, and the hollow rod 31 is located in the middle part of the annular piece 27. One of the inclined edges 25 is inserted into the inclined opening 23, the limiting ring 26 is engaged in the limiting groove 24, and the other inclined edge 25 is engaged in the annular groove 33. The pressure cap 21 is pressed into the mounting groove 22. During the pressing, one of the inclined edges 25 is pressed firmly against the inclined opening 23, and the other inclined edge 25 is tightly fitted against the annular groove 33 under the pressure of the pressure cap 21. The greater the pressure on the pressure cap 21, the greater the pressing force on the inclined edge 25, resulting in a stronger seal at the joint.

[0030] Example 2, as Figures 1-4 As shown, the rotating component 3 includes a hollow rod 31. An annular groove 33 is formed on the outer surface of the hollow rod 31. A sealing sleeve 36 is provided on the outer surface of the hollow rod 31. Two slots 32 are formed on the top of the hollow rod 31. A connecting rod 34 is provided inside the hollow rod 31. Two locking blocks 35 are fixed on both sides of the connecting rod 34. The two locking blocks 35 are correspondingly engaged inside the two slots 32. The other inclined side 25 is in contact with the annular groove 33. The sealing sleeve 36 is sealed to the connecting rod 34.

[0031] The effect achieved by the entire embodiment 2 is that when installing the camera 4, the camera 4 is connected by the connecting rod 34 so that the locking block 35 and the locking slot 32 can be engaged with each other, thereby facilitating the disassembly and installation of the camera 4.

The driving component includes a motor 6, which drives the rotating component 3 and the impellers 5 to rotate through gear transmission.

[0033] The effect achieved by the entire embodiment 3 is that when installing the camera 4, the connecting rod 34 extends into the hollow rod 31, causing the lifting plate 72 to be pressed downward. Under the elastic force of the spring 71, an upward thrust can be generated on the connecting rod 34, thereby firmly pressing the locking block 35 into the slot 32. At the same time, when the lifting plate 72 slides up and down, the mutual engagement and limiting of the guide groove 73 and the guide block 74 makes the sliding of the lifting plate 72 more stable. Furthermore, the impeller 5 is set on the outer shell 1, so that the entire device moves in the water flow inside the pipe.
