Anti-blocking tipping bucket type rain sensor

The invention discloses an anti-blocking tipping bucket type rain sensor which comprises a shell, a filter cone arranged in the shell, a funnel arranged below a water outlet hole of the filter cone, a tipping bucket arranged below a water outlet hole of the funnel, a cleaning needle with the upper end arranged in the water outlet hole of the filter cone and a control structure used for controlling the cleaning needle to move along the water outlet hole of the filter cone. According to the scheme, the cleaning needle is arranged below the filter cone, and the control structure controls the cleaning needle to move up and down to dredge the water outlet hole of the filter cone, so that the water outlet hole of the filter cone is prevented from being blocked. 本发明公开了一种防堵式翻斗式雨量传感器，包括壳体、置于壳体内的滤斗、置于滤斗的出水孔下方的漏斗和置于漏斗的出水孔下方的翻斗，还包括上端置于滤斗的出水孔内的清洁针和用于控制清洁针沿滤斗的出水孔移动的控制结构。本方案通过在滤斗下方设置一清洁针，通过控制结构控制清洁针上下移动实现对滤斗出水孔的疏通，避免滤斗出水孔堵塞。
