When the pulling catheter 133 is driven by the pressure control component 22, the guide tube 132 can be synchronously driven to pull the inflatable airbag 131. In this way, the inflatable airbag 131 can drive the guide plate 123 to gather inward along the reset torsion spring rod 121, thereby achieving the effect of clamping the debris. The air delivered to the pressure control component 22 by the transmission component 23 can be delivered from the guide pipe 132 to the inflatable airbag 131 through the lifting conduit 133, so that the inflatable airbag 131 can use the expansion of the filled air to expand the distance between the clamping components 15, thereby adapting to debris with larger shapes and improving the stability when clamping them.

The drainage plate 141 can draw the air pumped from the delivery tube rod 111 out of the air in the diversion airbag 143 through the drainage tube 142 and generate negative pressure, thereby providing the required negative pressure for the clamping component 15.

[0052] Among them, the clamping assembly 15 includes a clamping plate 151, a suction plate 152 and an intercepting net 153.

The clamping plate 151 can drive the suction plate 152 and the intercepting net 153 to move together with the movement of the guide plate 123, so that the debris to be cleaned can be clamped, and the suction plate 152 can adsorb various different debris through negative pressure, and adsorb the debris on the surface of the intercepting net 153, so as to further increase the way to grab the debris.

[0053] The working principle of this embodiment is as follows: First, the cleaning mechanism 1 is connected to an external power supply or a mobile power supply is installed. Then, the user holds the delivery pipe rod 111 and moves one side of the clamping plate 151 to the obstacle where the turbine runner needs to be cleared. Then, the air pressure environment in the pulling conduit 133 is changed by the operating mechanism 2, so that the inflatable airbag 131 can be adaptively expanded and contracted according to the size of the current turbine runner and the shape of the debris. When the inflatable airbag 131 drives the clamping plate 151 to adapt to the size of the two, the clamping plate 151 is placed on the outside of the debris, and then the operating mechanism 2 is pulled. The pulling conduit 133 will be driven by the operating mechanism 2 to pull the guide tube 132 to the guide tube 132. As the adjusting plate 122 rotates along the reset torsion spring rod 121, the clamping plate 151 will retract inward until the debris is clamped, and then the air pump 112 will be started. The air pump 112 will extract the air in the delivery pipe rod 111, and then the suction plate 152 will suck the air through the interception net 153, thereby sucking the debris. At the same time, the water remaining on the surface of the debris will follow the diversion air bag 143 through the drainage pipe 142 from the guide plate 141 into the delivery pipe rod 111, and finally be discharged from the air pump 112. After reducing the weight of the debris, the user can move the delivery pipe rod 111 to remove the debris from the turbine runner.

The positioning base 241 is used to limit the positioning tube 242 with the assembly tube 213 as the support point, so that the positioning tube 242 can guide the movement of the guide metal hose 221 and limit the positioning handle 243, so that the user can hold the positioning handle 243 and use the positioning handle 243 as the support point to pull the lifting handle 233 to achieve a stable lifting operation.

[0060] The working principle of this embodiment is as follows: First, the assembly tube 213 on the current threaded connecting tube 212 is connected to another identical threaded connecting tube 212 until the positioning handle 243 is moved to a position where the user can hold it. When the cleaning mechanism 1 needs to adapt to the shape of the debris and the gap between the debris and the turbine runner, the user controls the solenoid valve 232 to open, allowing the suction pump 223 to send air into the cleaning mechanism 1 from the guide metal hose 221 through the flow pipe 222 until the cleaning mechanism 1 adapts to the gap between the turbine runner and the shape of the debris, and then closes the solenoid valve 232. The user then holds the positioning handle 243 and pulls the lifting handle 233, so that the lifting handle 233 can drive the flow pipe 222 to pull the guide metal hose 221, thereby allowing the cleaning mechanism 1 to clamp the debris. At this time, the user can drive the cleaning mechanism 1 to move the debris away from the turbine runner by holding the positioning handle 243 and the lifting handle 233.
