Description
Technical Field
The invention relates to the field of river environment garbage cleaning equipment, in particular to a Venturi effect controlled unpowered water surface garbage collector.
Background
China generates huge amount of garbage every year, wherein floating garbage accounts for a certain proportion. The water surface floating garbage refers to water quality deterioration water bodies floating on the upper layers of various water bodies (river channels, lakes, landscape water areas and the like) and various wastes obstructing the view. The water surface treatment device mainly comprises living sundries discarded by people at will, various marine products discarded by water surface sailing ships, dead aquatic animals and plants, surface plants flushed to a water body due to wind blowing, rain falling and the like, and the like. Part of floating garbage is accumulated on water areas such as rivers, lakes and the like, so that the water body is greatly polluted, and the survival of aquatic animals and plants is seriously influenced, so that the garbage needs to be collected and cleaned regularly.
At present, the main collection mode of river course rubbish is comparatively single, what generally adopted is comparatively original manual salvage's method, stands on the ship by the handheld string bag of staff and directly salvages the surface of water floater promptly. This kind of mode needs more labour, and operating condition is poor, and is consuming time more, and efficiency is lower. On the basis, various water surface garbage salvage ships are developed in all countries of the world, mainly operate mechanically and operate in a manual mode when necessary.
A mechanical water surface floater collecting device is mainly divided into a conveyor belt type, a bucket type, a rotary type, a grab type and the like according to different salvaging modes. However, from the collected hull parameters of various ships, the ships have large models and are not limited by regions, and the ships are not suitable for garbage collection in small watersheds. (for example, the length of the water cleaning ship is 7.4 m, and the length, the width and the height of the ocean cleaning flat-bottomed ship are respectively 30 m, 10 m and 2.3 m) so that a small garbage collector is to be developed, which can be separated from manpower, can automatically collect garbage, and greatly saves the manpower and reduces the cost through uniform secondary recovery treatment.
