Well-tube water-filtering part of water-collecting deep well

集水深井的井管滤水部

Abstract

The utility model relates to a well-pipe water filtering part of a water collecting deep well. A water filtering part has the structure that a plurality of water inlet holes are evenly distributed on the pipe wall of a well pipe in the water collecting deep well. The outside of the well pipe is provided with a filtering net which can filter out the foreign body in covering way and can only be used for underground water going into, wherein, a plurality of longitudinal tie strips are evenly distributed on the wall surface of the outside of the water filtering part of the well pipe in convex way. The filtering net can be abutted on the covered water filtering part at the outside of the tie strips to make a gap arranged between the filtering net and the water inlet hole of the pipe wall. When the underground water can pass through the water filtering part to flow into the well pipe, the water flow and the water flow pressure can fully be dispersed by the structural design; the utility model has the characteristics of avoiding the outside foreign body concentrating on somewhere of the filtering net to lead to blocking condition; simultaneously, the utility model has the efficiency of reducing the damage of the filtering net caused by the high pressure water flow, etc.
一种集水深井的井管滤水部,该滤水部是集水深井中的井管管壁均设有数个进水孔的部分,且其外侧包覆设有一可滤除杂物仅供地下水进入的滤网所构成,其中在井管滤水部的外侧壁面上均布凸设有数条纵向的枕条,并使滤网抵靠枕条外侧包覆滤水部,令滤网与管壁进水孔间留有间隙。通过以上结构设计,当地下水经滤水部流入井管时,可充分分散水流及水流压力,而具有能够避免外界杂物集中于滤网某处阻塞,同时可降低高压水流对滤网的损坏等功效。
