s2: when the buffer tank (4) is impacted by water waves, the buffer tank (4) moves backwards under the impact of the water waves, the buffer tank (4) is connected with a buffer mechanism through a connecting rod (17), the water waves can be buffered under the action of the buffer mechanism, so that the impact of the water waves is relieved, and when river water is cooled down, the buffer tank (4) is reset under the action of a telescopic spring in the buffer mechanism, so that the impact force of the river water on the dam body (1) is buffered repeatedly;

s3: the water inlet is formed in the buffer tank (4), when the buffer tank (4) is hit by river water, garbage can be driven to enter the buffer tank (4) through the water inlet, two rows of barbed nails (23) are arranged on two sides of the water inlet of the buffer tank (4), and through the arrangement of the barbed nails (23), when the river water is cooled down, the garbage can be remained in the buffer tank (4) under the action of the barbed nails (23), so that the garbage in the river water can be collected;

s4: when rubbish in buffer bin (4) is too much, start spiral advancing mechanism this moment, with rubbish propelling movement to buffer bin (4) upper end, then be being connected blow off pipe (6) and collection mechanism through the connecting pipe, after connecting, in starting the collection mechanism rubbish pump (28) take out the collection mechanism with the rubbish in buffer bin (4) through blow off pipe (6), collect rubbish.
