Passive automatic opening and closing water gate

Abstract

The invention discloses a passive automatic opening and closing water gate, and belongs to the technical field of sea salt production. The passive automatic opening and closing water gate comprises acommunication pipeline, a lifting beam type telescopic pipe, an automatic opening and closing mechanism frame, a gate opening lifting beam barb, a counterweight buoy, a buoy guide cylinder, a gate closing barb, a limiting pin pull rod and a counterweight drop hammer, wherein the lifting beam type telescopic pipe sleeves a water outlet of the communication pipeline, a telescopic pipe inhaul cable is connected to the top of the lifting beam type telescopic pipe, the telescopic pipe inhaul cable is wound around a limiting pin of the limiting pin pull rod and is connected with one end of a hangingrope lever, and the counterweight drop hammer is connected to the other end of the hanging rope lever. According to the passive automatic opening and closing water gate, the counterweight buoy movesup and down under the lifting action of the downstream liquid level, and the lifting beam type telescopic pipe naturally falls or rises, so that gate opening and gate closing are realized, the currentsaltern production status can be met, unmanned supervision is realized, the production efficiency is improved, and labor force is liberated.

Description

technical field [0001] The invention relates to the technical field of sea salt production, in particular to a passive automatic opening and closing sluice. Background technique [0002] Generally speaking, there are usually two gates and ditches in a salt factory, and at least three people need to be assigned to take turns in charge of water source dispatching. Summer is both the peak season for salt production and the season for flood control. It is even more necessary to increase personnel monitoring work, which virtually increases labor costs and increases hidden dangers in production safety. The more personnel invested, the higher the risk of safety production. In addition, there are aging types of work such as brine making, crystallization, and re-sunning in the current salt field, and the lack of intensive labor force. The personnel renewal of various types of salt production that rely solely on labor has entered a bottleneck period. What's more, 95% of tidal flats ...

AI Technical Summary

Problems solved by technology

Summer is both the peak season for salt production and the season for flood control. It is even more necessary to increase personnel monitoring work, which virtually increases labor costs and increases hidden dangers in production safety.

The more personnel invested, the higher the risk of safety production

In addition, there are aging types of work such as brine making, crystallization, and re-sunning in the salt field, and the lack of intensive labor force. The renewal of personnel for various types of salt production that relies solely on labor has entered a bottleneck period.

Another thing is that 95% of tidal flats are surrounded by water, the amount of wiring work is large, and they are prone to aging

Therefore, the gates are basically started and stopped manually. The workload is heavy, the job conditions are difficult, and there are safety risks such as drowning and falls.
