<p>The present invention relates to an auto-lifting water sampler apparatus for a manhole. According to the present invention, the auto-lifting water sampler apparatus for a manhole in the auto-lifting water sampler apparatus installed vertically in a manhole of a sewage conduit with a water sample bin (130) rising and falling to collect a sewage sample on the bottom of the manhole, comprises: a body (110) including a bottom frame (111) made of a stainless steel pipe having a hollow part inside and a top frame (112) which has a space to have a main rotating shaft (102) for being fixated and secured in a longitudinal direction of a top of the bottom frame (111) and rotating by the driving power of a driving motor for a transfer chain (101), formed as a plane-shaped plate with openings on one side and the other side; a body leg unit (140) attached to the bottom of the bottom frame (111) of the body (110) including three legs whose height can independently be controlled to keep the body (110) horizontal; and a transfer chain (150) formed as a chain wound or unwound along a circumference of one side and another side of the body (110) to elevate and lower the water sample bin (130). Therefore, the present invention automatically collects sewage sample from a manhole of a sewage conduit at a certain time interval, and can be installed in the manhole; thereby preventing damage or loss.</p> |
