The invention relates to a dredging device for water treatment, comprising a sludge pump and a rotary mechanism, the mud inlet end of the sludge pump and the rotary mechanism are connected through a connecting pipe, and the rotary mechanism includes a first right angle Elbow, the top of the first right-angle elbow is rotatably installed with the rotating sleeve, and the bottom end of the first right-angle elbow is telescopically connected to one end of the overload pipe through the first telescopic tube; while the circling mechanism rotates, through When the first servo motor is working, the rotating active gear drives the meshing first transmission gear to rotate, and the coaxial rotation of the first worm wheel is realized through the first rotating shaft. The length adjustment of the slewing mechanism is realized, so the slewing mechanism rotates synchronously while the slewing mechanism expands and contracts, and the dredging operation is completed through regular movement, ensuring the same degree of dredging at different parts of the river, which greatly improves the overall dredging efficiency.

The invention discloses a locking structure for lashing ships. The invention relates to the technical field of lashing and locking ships. A novel locking structure for lashing ships includes an arc-shaped plate, a first shackle, a second shackle and a chain ring. The first shackle and the second shackle are respectively parallel to the left and right ends of the arc plate, and there are two chain ring groups, which are arranged symmetrically between the first shackle and the second shackle and the arc plate. ;The chain ring group includes the left chain ring, the middle chain ring and the right chain ring, and the center of the right end of the left chain ring and the center of the right end of the middle chain ring are horizontally fixed with sleeves, and the inside of the sleeve has a "thread" structure, and the left end of the middle chain ring Both the center and the center of the left end of the right chain ring are horizontally fixed with a threaded shaft, and the end of the threaded shaft is screwed into the casing so that the left chain ring and the right chain ring are respectively threaded on both sides of the middle chain ring, and the center of the left end of the left chain ring is horizontally fixed with a round rod The beneficial effects of the present invention are: to realize the adjustment of the length of the chain / enhance the connection between the hook and loop.

The invention relates to a motor slot wedge clamp. The motor slot wedge clamp comprises a mould plate. A fixed baffle is arranged on one side of the upper surface of the mould plate in the width direction of the mould plate, a plurality of columns of bolt hole sets are formed in the other side of the upper surface of the mould plate in the length direction of the mould plate, and each column of bolt hole set comprises first mould plate bolt holes formed at intervals in the width direction of the mould plate; an adjustable baffle is arranged on the upper surface of the mould plate and connectedwith the first mould plate bolt holes through first bolts penetrating through adjustable baffle bolt holes; a plurality of second mould plate bolt holes are formed in the position, on the inner sideof the fixed baffle, of the upper surface of the mould plate at intervals in the width direction of the mould plate; and a top plate is arranged on the upper surface of the mould plate, is in an L shape and is connected with the second mould plate bolt holes through second bolts penetrating through top plate bolt holes, and the free end of the short edge of the top plate is connected with the fixed baffle in an abutting mode. The motor slot wedge clamp can clamp a plurality of slot wedges at a time, so that the assembling efficiency is improved, the thickness of the machined slot wedges can beensured, and assembling workload and cost are reduced.
