The length of the hollow cavity in the radial direction is smaller than that of the inner cylinder in the radial direction, in the example, the length of the hollow cavity in the radial direction is only two thirds of that of the inner cylinder in the radial direction, other lengths, volumes or volume ratios of the hollow cavity and the inner cylinder can be set according to the relation between actual gravity and buoyancy, the volume of the hollow cavity is reduced, the buoyancy of the inner cylinder is reduced, the rising critical water level of the inner cylinder is reduced, the inner cylinder can descend without discharging more water after the inner cylinder rises, the speed of the device for collecting garbage is increased, meanwhile, the collecting device can be operated more easily at the moment of starting, the collecting device can operate normally in a shorter time, the device can operate normally only in 10 minutes after the volume of the hollow cavity is reduced, and the starting time of the device is greatly shortened.

This patent is direct to be kept apart the net bucket and set up on the support frame or outer barrel bottom, has cancelled the net baffle in the outer barrel, keeps apart the net bucket in the collection device before and arranges in on the net baffle, but long-term use or artificial misoperation have a lot of rubbish to pile up on the net baffle, cause the net baffle to hardly wash on the one hand, on the other hand the net baffle is covered by rubbish, causes drainage mechanism drainage difficulty, influences the collection efficiency of surface of water rubbish. After the screen partition plate is cancelled, small garbage which is not collected into the filter screen is directly discharged through the drainage mechanism.

This patent simple structure, convenient to use, manufacturing cost are lower, can fully collect water surface rubbish completely, and it is fast, efficient to collect water surface rubbish, and a running cycle can collect the surface of water rubbish of bigger capacity.

The inner tube constantly rises and descends, and water flows to the inner tube center, and rubbish on the surface of water flows into the filter screen in the inner tube along with rivers, and the inner tube constantly reciprocates and can make the rivers that pour into the inner tube fast time slow, and outer bucket surface of water is big time spent to the surface of water tension that the inner tube center produced to the surface of water big time spent to give the surface of water rubbish of moving at the inner tube center constantly with higher speed for the collection efficiency of surface of water rubbish, also enlarged simultaneously the radiating area of collection device collection rubbish.

The filter screen is preferably flexible filter screen, sets up cuff and longer length on the filter screen for the filter screen does not rise and descend along with the inner tube, has reduced the weight that bears when the inner tube rises, helps the inner tube to prolong the time and the frequency of reciprocating, helps collecting more surface of water rubbish, very big improvement the filter screen collect the maximum capacity of surface of water rubbish, help improving the efficiency of collecting the surface of water rubbish.
