Gate opening detection device

Abstract

The invention discloses a gate opening detection device. The device consists of a measuring rod, a long-stroke displacement sensor, an anti-sway component and a mounting bracket, wherein the long-stroke displacement sensor is used for detecting the actual position of the measuring rod in an opening or closing process of a gate for acquiring a gate opening electric signal; the long-stroke displacement sensor is arranged on the edges on the two sides of the gate; the measuring rod matched with the long-stroke displacement sensor is arranged inside or outside a water retaining working surface ofa gate structure; the mounting frame is fixed on a side wall of a gate wall; and the mounting bracket is connected with the long-stroke displacement sensor through the anti-sway component. The gate opening detection device has less conversion links, little outside influence, high detection accuracy, safety, reliability and low cost, is easy to manufacture, adopts a rigid structure, improves the adaptive capacity to a severe environment, and is convenient to install and maintain due to the adoption of external arrangement.

Description

technical field [0001] The invention relates to the field of gate opening detection, in particular to a gate opening detection device. Background technique [0002] Arc gates and vertical slab gates are key equipment for controlling flood control and power generation in the water conservancy and hydropower industry. For the structure of the arc gate, see figure 1 and figure 2 As shown, the door leaf structure 5 of the curved gate is a water-retaining working surface, and the support arms 11 are located on both sides of the water-retaining working surface 5 of the curved gate. Gate hinge shaft 12, hydraulic hoist oil cylinder 14 top is provided with hydraulic hoist oil cylinder hinge shaft 15, the arc gate passes through arc gate hinge shaft 12 and hydraulic hoist oil cylinder hinge shaft 15 four fulcrums Supports, installed in the channel between two concrete gate walls. The arc-shaped gate is lifted by two sets of hydraulic hoists installed on both sides of the gate wa...
