Water level gauge switch valve for intelligent water conservancy system

Abstract

The invention provides a water level gauge switch valve for an intelligent water conservancy system, which comprises a shell and a bottom plate, wherein the shell covers the bottom plate. The water level gauge switch valve is characterized by further comprising a valve element, a small contact piece and a large contact piece; the valve core is arranged in the shell; the valve element comprises anoperation end, a limiting end and a contact end from top to bottom; the operation end is arranged at the upper end of the limiting end; the small contact piece sleeves the contact end; a circular groove is formed in the middle of the lower end of the limiting end; the large contact piece sleeves the outside of the circular groove; the bottom plate is provided with a first upper contact piece and asecond upper contact piece which are in contact fit with the large contact piece, and a first lower contact piece and a second lower contact piece which are in contact fit with the small contact piece; the first upper contact piece/the second upper contact piece is electrically connected with the first lower contact piece/the second lower contact piece; a limiting hole is formed in one side of the limiting end; a limiting ball is arranged in the limiting hole; the limiting ball is connected with the limiting hole through a limiting spring; the shell is provided with a round hole correspondingto the limiting ball; the contact end is provided with a compression spring; one end of the compression spring is fixed with the circular groove, and the other end is connected with the small contactpiece; the bottom plate is provided with a groove corresponding to the contact end. Switching can be controlled by rotating, so that a water level gauge is easier to switch between power-on and power-off.

Description

technical field [0001] The invention belongs to the field of water level measuring equipment, and in particular relates to a water level gauge switch valve limit structure for a smart water conservancy system used in the smart water conservancy industry. Background technique [0002] The water level gauge is a commonly used monitoring equipment in the water conservancy industry. Traditionally, there are float type, optical fiber water level gauge, ultrasonic water level gauge and other water level gauges. Later, some water level gauges were made into tubes. In this type of water level, the outer tube is equipped with a sensor or circuit board for measuring the water level, and the sealing cover on the top of the outer tube is set as a switch. The traditional switch is mostly push-button type. The button is easy to accidentally press and cause abnormal opening or closing. However, with the development of the smart water conservancy industry, the water level gauge needs to ru...

Problems solved by technology

Later, some water level gauges were made into tubes. In this type of water level, the outer tube is equipped with a sensor or circuit board for measuring the water level, and the sealing cover on the top of the outer tube is set as a switch. The traditional switch is mostly button type. Buttons are easy to accidentally press and cause abnormal opening or closing

However, with the development of the smart water conservancy industry, the water level gauge needs to run continuously for a long time to ensure the real-time data collection of the smart water conservancy platform. Therefore, the traditional button switch is easy to cause abnormal opening or closing, which affects data collection.
