Mud/sludge removing device

Abstract

A mud removing device includes a case which is merged into water and has an opening and a space. At least one at suction tube and multiple injection tubes respectively extend and connect to the case. The injection tubes are located around the opening of the case and one end of the injection tubes reaches to the periphery of the opening. A working station introduces high pressure water to flush the mud located below the opening of the case and at least one the suction tube sucks the mud which is collected to the working station. The case has weights and the working station can be carried by a floating carrier. The working station has a crane which has a cable to hang the case.

1 . A mud removing device comprising:
 a case having an opening and a space defined in the case, the case having at least one holding unit and at least one weight, the at least one holding unit connected to outside of the case and holding the at least one weight;   at least one suction tube connected to the case and a first end of the at least one suction tube extending through the case and communicating with the space, a second end of the at least one suction tube connected to a working station via a hose;   at least one injection tube, connected to the case and a first end of the at least one injection tube extending through the case and inserted into with the space, a second end of the at least one injection tube connected to a working station via a high-pressure water tube, and   the working station providing high-pressure water to the injection tube via the high-pressure water tube so as to inject the water toward the opening of the case, and the working station generating suction force to the at least one suction tube via the hose.   
     
     
         2 . The device as claimed in  claim 1 , wherein there are multiple injection tubes evenly located close to a periphery of the opening. 
     
     
         3 . The device as claimed in  claim 1 , wherein the working station is located on a floating carrier. 
     
     
         4 . The device as claimed in  claim 3 , wherein the floating carrier is a boat with power. 
     
     
         5 . The device as claimed in  claim 1 , wherein the at least one suction tube has a suction hole connected to the first end thereof and the suction hole has a filtering net connected thereto. 
     
     
         6 . The device as claimed in  claim 1 , wherein the at least one suction tube is located at a recessed and curved top of the case. 
     
     
         7 . The device as claimed in  claim 6 , wherein the at least one suction tube has at least one ring connected thereto which is connected to a cable of a crane of the working station. 
     
     
         8 . The device as claimed in  claim 7 , wherein the cable has a hook which hooks the ring. 
     
     
         9 . The device as claimed in  claim 1 , wherein the at least one weight is removably connected to the at least one holding unit which is connected to outside of the case. 
     
     
         10 . The device as claimed in  claim 9 , wherein there are multiple weights and holding units evenly located around the opening of the case. 
     
     
         11 . The device as claimed in  claim 9 , wherein the at least one holding unit has two parallel holding members and each holding member has a slot, the at least one weight is a plate and two sides of the at least one weight are inserted into the slots of the two holding members.
