Flow velocity monitoring device for channel silted water
The invention provides a flow velocity monitoring device for channel silting water. The fixing frame is fixedly installed at the bottom of one side of the drainage channel, the alarm box is slidably installed on one side of the fixing frame, and the electric gate is arranged on the side, close to the fixing frame, of the drainage channel. A water absorption triggering mechanism is arranged through water level rising, dilute sulphuric acid and active metal are promoted to be mixed to generate hydrogen, the alarm box rises after the hydrogen is generated, then a sliding contact and a sliding resistor are controlled through gradually-rising buoyancy to change the current of the electric gate, the electric gate is gradually opened, and rapid drainage is conducted on a water channel; and the rising alarm box drives the feeler lever to trigger the touch switch B, so that an alarm is given to remind a worker that the water level still cannot be lowered after the water gate is completely opened, the worker is notified to make preparation for maintenance in advance, and the subsequent harm caused by flood is reduced.
本发明提供一种用于渠道淤积水流速监测装置，包括；排水渠、固定架、警报箱、电动闸门，排水渠一侧底部固定安装有固定架，固定架一侧滑动安装有警报箱，排水渠靠近固定架一侧设置有电动闸门。通过水位上升设有吸水触发机构，促使稀硫酸与活泼金属混合产生氢气，氢气产生后使警报箱上升，进而通过逐渐上升的浮力控制滑动触头与滑动电阻改变电闸门的电流大小，使电闸门逐渐开大对水渠进行快速排水，尽量避免水位持续上升溢出水渠造成危害，通过上升的警报箱带动触杆触发触动开关B，进而发出警报提示工作人员水闸完全打开后水位依然无法下降，通知工作人员提前做好维护准备，减少了洪涝后续造成的危害。
