Problems solved by technology

[0002] In order to ensure that there is water suitable for the growth of crops in the farmland, a water level monitor is used to monitor the water level in the farmland. The water level monitor is installed on the ground of the farmland. When the liquid in the farmland increases, the liquid flows along the water inlet pipe of the monitor. into the connecting pipe, the liquid pushes the sliding ball inside the connecting pipe to move, and the sliding ball pushes up the liquid in the reading plate to indicate the reading; when the monitor is used to monitor the water level in the farmland in the prior art, due to the water in the farmland Contains weeds, the weeds in the liquid entering the connecting pipe are first filtered through the filter screen and then passed in, and the small weeds are easy to get stuck in the filter holes of the filter screen, causing the diameter of the filter holes to shrink and lead to the connecting pipe The filtration speed of the liquid is slowed down, the thrust of the liquid on the sliding ball is reduced, and the moving speed of the sliding ball is slowed down, which causes the monitor to deviate from the water level monitoring value in the farmland

Abstract

The invention discloses water utilization coefficient farmland water level monitoring equipment which structurally comprises a reading dial, a connecting pipe and a water inlet pipe. As fine weeds are easily clamped in filter holes of a filter screen, an expansion plate is arranged at the bottom of a sliding ball, the expansion plate moves up and down to impact the filter screen so that the weeds in the filter holes of the filter screen fall off and are discharged, and the filter screen is pushed to vibrate so that impurities at the bottom shake and fall off. The filtering speed of liquid introduced into a connecting pipe can be increased, the thrust of the liquid to the sliding ball is increased, the moving speed of the sliding ball is increased, and the phenomenon that the water level monitoring value of a farmland monitored by a monitoring instrument is deviated is reduced. Due to the fact that liquid is introduced into a pipe body for a long time and moss grows on the inner wall of the pipe body, pushing blocks are arranged on the two sides of the sliding ball, the moss on the inner wall of the pipe body is removed through removing rings in the pushing blocks, the original diameter of the inner wall of the pipe body can be kept, and the sliding ball can freely move up and down in the pipe body.
