Example 1
Referring to fig. 1 to 4, the invention provides a cleaning device for the interior of a water conservancy pipeline, which comprises a cleaning component 1 positioned at the front end of the device and a moving component 2 connected with the cleaning component 1, wherein the moving component 2 is used for pushing the cleaning component 1 to move in a pipeline 100;
the cleaning assembly 1 comprises a supporting cylinder 11 corresponding to the inner diameter of a pipeline 100 to be cleaned, the supporting cylinder 11 is an annular cylinder, one end, away from the moving assembly 2, of the cleaning assembly 1 is the front end of the device, a cleaning ring 12 is fixedly arranged at the front end of the supporting cylinder 11, a shaft rod 13 is coaxially and fixedly arranged in the supporting cylinder 11 of the cleaning assembly 1, a fixing plate 14 is fixedly arranged between the front end of the shaft rod 13 and the inner wall of the cleaning ring 12, and a movable plate 15 is arranged on one side of the fixing plate 14; the movable plate 15 rotates with the shaft rod 13 as an axis and the inner wall of the cleaning ring 12 as an outer ring rotation track;

By this structure, the screw propeller 21 is adopted as the power output structure of the moving assembly 2, and compared with the ordinary wheel structure or crawler structure, the propelling structure of the screw propeller 21 is more suitable for traveling in the water conservancy pipeline 100, because the water conservancy pipeline 100 is the annular pipeline 100 and is wet and slippery inside, the propelling structure of the screw propeller 21 has better adaptability to the traveling surface and is easier to travel than the wheel structure and the crawler structure. In addition, because the water conservancy pipeline 100 is internally deposited with sludge, the deposited wet and slippery sludge easily affects the driving components of the wheel type structure and the crawler type structure, and the driving component of the screw propeller can be hidden inside and can be more easily rid of the sludge through the external screw blade.

cavities are arranged in the fixing plate 14 and the shaft rod 13, an air pump is arranged in the moving assembly 2, and the inner annular air bag and the outer annular air bag are communicated with the air pump through the fixing plate 14 and the shaft rod 13.
When the device advances, the air pump pumps air, so that the inner and outer annular air bags are contracted, the movable plate 15 is positioned at one side of the fixed plate 14, and when the device moves to the working position, the air pump inflates, the inner and outer annular air bags are expanded, so that the movable plate 15 moves to the other side of the fixed plate 14.
Because the inner diameter of the inner annular air bag 32 is smaller than the outer diameter of the rail 16, and the outer diameter of the outer annular air bag 33 is larger than the inner diameter of the cleaning ring 12, when the cover surface 3 is unfolded, the inner and outer annular air bags can be ensured to be tightly attached to the rail 16 and the cleaning ring 12 respectively under the air pressure of the air pump.
Example 3
On the basis of embodiment 2, the cleaning ring 12 and the shaft 13 are provided with annular baffles on one side of the outer annular air bag 33 and one side of the inner annular air bag 32.
Adopt baffle structure, can play the limiting displacement of interior outer annular gasbag after interior outer annular gasbag is aerifyd to avoid the excessive deformation of overlay 3 atress.

The effect obtained by adopting the structure is that one end of the movable plate 15 far away from the shaft rod 13 has a certain movement allowance in the annular groove 121, and one action is that when the movable plate 15 is close to the fixed plate 14, the movement allowance of the limiting block 153 can make the movable plate 15 close to the fixed plate 14. The other function is that the movement margin of the limiting block 153 allows the movable plate 14 to rotate more easily in cooperation with the annular groove 121 when the cover 3 is opened, and is not easily jammed.

Since the blades of the screw propeller 21 are not a single direction driving force when they are in frictional force with the inner wall of the duct 100, but an oblique force is applied to the inner wall of the duct 100, if the screw propellers 21 having a set of screw blades in the same direction are rotated in the same direction, the moving member 2 is moved forward or backward while being rotated. By adopting two sets of screw propellers 21 with opposite screw blades, when the two sets of screw propellers 21 rotate in the same direction at the same time, the forces in the rotating direction of the inner wall of the pipeline 100 after the oblique force is decomposed can be neutralized, and only the driving force in the axial direction of the pipeline 100 is left. When the rotation directions of the two sets of screw propellers 21 are opposite, the pushing force along the axial direction of the pipeline 100 is neutralized, and at the moment, the two sets of screw propellers 21 superpose the rotating force along the inner wall of the pipeline 100, so that the device can rotate in situ in the pipeline 100.
