Rain water collecting beaker - has dirty water drain in base of ringed wall section having sloping walls and has cover set on supports lying on wall rim

摘要

There is a dirty water drain (2) which is fed from the ring wall (5) as the inner diameter of the wall is the same as the diameter of the drain. The wall outer diameter is 0.18 - 0.4 times the inner diameter of the beaker (1). A support (9) for the beaker cover is arranged centrally on the rim of the wall. The upwards sloping outer walls (7) of the ring wall slopes at an angle of 45 deg. and the inner walls slope at an angle of 30 deg.. ADVANTAGE - Provides for constant cleaner water and because of this drain, the height of the dirt collector does not need to be altered.
