Description

technical field

[0001] The invention belongs to the field of earth-rock dam measurement, in particular to an automatic water pipe type settlement instrument measurement device. Background technique

[0002] The water tube type settlement instrument is made of the principle of a connector, and is mainly used for vertical displacement monitoring of earth-rock dams. It is composed of the probe buried in the measured point, the observation pipe in the observation room, the connecting pipes (including water inlet pipes, drain pipes, ventilation pipes) and protective pipes connecting the two. The observation tube is connected to the sinking probe through the water inlet pipe, and the vent pipe keeps the air pressure in the sinking probe consistent with the outside world. When the water cup in the sinking probe is filled with water and overflows, the water level in the observation tube is equal to the water level in the water cup of the probe. The amount of water level change in t...

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] Such as Figure 1-8 As shown, a kind of automatic water pipe type sedimentation meter measuring device includes an observation screen and a measurement and control box. Several observation tubes 6 are arranged in the observation screen 5, and a temporary water tank 2 is arranged behind the observation screen 5. The temporary water tank 2 Connect with each observation tube 6 through a pipeline; a pressure sensor 7 is installed under each observation tube 6; the observation screen 5 is connected with a water storage bucket assembly 4 through a pipeline;

[0031] The water storage bucket assembly 4 includes a water storage bucket 5, a liquid level switch 9, a connecting pipe 10, a booster pump 11 and a four-way valve 12; wherein, the water storage bucket 5 is provided with a liquid level switch 9 on the inner wall, and the water storage bucket 5 is provided with a...
