Abstract

The invention belongs to the technical field of gate sensors, and specifically discloses a gate opening degree sensor, which comprises a limiting rod and a mounting bracket, a rack is arranged on oneside wall of the limiting rod, the mounting bracket is connected witha detection gear through a pin shaft, and the detection gear and the rack are coupled; one end of the mounting bracket is fixedly connected with a rotation speed sensor in a threaded mode, the rotation speed sensor and the detection gear aremounted on the same side, the detection end of the rotation speed sensor faces towards thedetection gear,the detection gear rotates through the meshing action between the rack and the detecting gear, thus the detecting basis of the rotating speed sensor is provided, the detection is convenient, the installation method is simple, and water erosion is unlikely; by using the rotation speed sensor and the detection gear cooperatively, data detection is relatively accurate; and through theinstallation method of the mounting bracket and the rotation speed sensor, installation and disassembling are convenient, and subsequent maintenance is more convenient.

Description

technical field [0001] The invention relates to the technical field of gate sensors, in particular to a gate opening sensor. Background technique [0002] The sluice is a low-head hydraulic structure built on the banks of rivers, channels, reservoirs, and lakes, and has the functions of retaining and releasing water. Closing the gates can block floods, block tides, and raise water levels to meet the needs of upstream water intake or navigation; opening gates can discharge floods, drain water, flush sand, draw water, or adjust flow according to downstream water needs. By controlling the opening scale of the sluice gate, the water discharge and storage capacity of the sluice can be strictly controlled. [0003] For example, Chinese Patent Publication No. CN107289853A provides an underwater gate opening sensor, including a housing, a stator fixed in the housing, a rotor located in the housing, continuous windings, several sine windings, and several cosine windings; the rotor i...
