This utility model discloses a simple, tiltable flap gate with a movable pipe opening, relating to the field of valve technology. The utility model includes a drain pipe with a base mounted on its surface and a door cover on one side of the drain pipe. A reset assembly is located on one side of the base, comprising fixed pulleys on the front and rear sides of the base and a steel cable sleeved on the surface of the fixed pulleys. Through the mechanical linkage design of the reset assembly, this utility model achieves an automatic reset function without external power. A counterweight is connected to the door cover via the steel cable; when the water pressure decreases, the weight of the counterweight can quickly pull the door cover closed, avoiding the failure risk of traditional electric or hydraulic flap gates due to power outages or malfunctions. The door cover adopts a structure connecting a pivot to a bracket, allowing it to rotate flexibly in a tilted state to adapt to different drainage angles, especially suitable for scenarios where the drain outlet angle changes frequently, significantly improving applicability and reliability.

The utility model discloses a kind of rubbish cleaning clamps, including connecting rod, handle, clamping mechanism and pulling mechanism, handle is set to the upper end of connecting rod, pulling mechanism includes the pull rod of cross bar and connection, pull rod slides up and down along the inside of connecting rod, clamping mechanism is set in the lower end of connecting rod, including positioning head, movable head, linkage and three groups of clamping arms, movable head is connected with linkage by first connecting rod, linkage includes fixed base, three second connecting rods and corresponding pin joint arm, pin joint arm is connected with clamping arm respectively, the lower end of each clamping arm is equipped with chuck, positioning head is equipped with guide slot inside for guiding movable head sliding, the structure can realize the synchronism of three claw clamping operation, improve clamping stability, adopt spring automatic reset mechanism to improve operating efficiency, chuck uses antiskid rubber material to enhance friction, linkage structure movement coordination, effectively solve existing rubbish clamp clamping unstable, transmission out of sync, reset inconvenient and clamping object easy to slip off and other problems.
