IoT-based smart valve

Abstract

The invention discloses an intelligent valve based on the Internet of Things. There is a rotary drive motor on the top, and the rotary drive motor is connected downward with a turntable. The lower surface of the turntable is provided with a number of telescopic rods evenly distributed along the circumference. The telescopic rod is connected with a telescopic drive motor. The keyhole ring on the outer edge of the handwheel, and several telescopic rods are correspondingly inserted into the keyhole ring. The invention has the advantages of directly adding a lock on the basis of the existing valve without changing the basic structure of the existing valve to realize the automatic opening and closing of the valve and the automatic unlocking or locking of the lock, and the total cost of the valve is low.

Description

technical field [0001] The invention relates to a valve, in particular to an intelligent valve based on the Internet of Things. Background technique [0002] In the water conservancy and hydropower industry, hundreds of valves of various forms need to be used. Valves are pipeline accessories used to open and close pipelines and control the flow direction. Valves are directly connected and installed with pipelines. Traditional valves require manual statistics, Manual switch, when the number of valves is large, it is easy to make mistakes. The switch of some larger valves is generally controlled by the valve handwheel. The valve handwheel needs to be manually rotated by the staff. In some important installation occasions, the valve needs to be locked with a lock to prevent idle confusion. People mistakenly open and close the valve by turning the valve handwheel, causing unnecessary financial losses and even safety accidents. [0003] On the road towards automation, valve elec...

Problems solved by technology

[0002] In the water conservancy and hydropower industry, hundreds of valves of various forms are needed. Valves are pipeline accessories used to open and close pipelines and control flow direction. Valves are directly connected to pipelines. Traditional valves require manual statistics, Manual switch, when the number of valves is large, it is easy to make mistakes. The switch of some larger valves is generally controlled by the valve handwheel. People mistakenly open and close the valve by turning the valve handwheel, causing unnecessary financial losses and even safety accidents

[0003] On the road towards automation, valve denso is already a relatively common technology. The opening and closing of valves can be controlled remotely through the control system. However, for valves with locks, denso valves still inevitably need Open and close the valve on site. The valve lock is nothing more than the traditional mechanical lock using a key to unlock and the current electronic lock. The advantage of the mechanical lock is that it is cheap and the unlocking method is stable. However, for some valves, the quantity For many water conservancy and hydropower enterprises, it often happens that the operation and maintenance operators carry a tool bag with a pile of heavy chain locks, metal padlocks and safety signs in the bag, and register the metal one by one when operating in the underground factory. Number the keys of the padlock, and carefully put these keys back into the "second-class key cabinet" immediately after the operation is completed. The convenience of the lock switch is low, time-consuming and laborious

The electronic lock is an electronic product that controls the circuit or chip work through password input, thereby controlling the closing of the mechanical switch, and completing the tasks of unlocking and locking. Although it overcomes the disadvantages of less passwords and poor convenience of use in mechanical coded locks, both fingerprint coded locks and digital coded locks require the cooperation of professional processing chips and sensors to achieve switch requirements. The high cost is not suitable for pumped storage power plants and other applicable occasions with hundreds of valves
