Wireless liquid level alarm

Abstract

The invention discloses a wireless liquid level alarm which comprises a liquid level monitoring module, an alarm module, a wireless signal transmitter, an acousto-optic signal receiver and an acousto-optic alarm module, and the liquid level monitoring module comprises a liquid level sensing block, a power module, an electromagnetic relay, a liquid level device and liquid. The liquid level sensing blocks comprise a first liquid level sensing block and a second liquid level sensing block, the power supply module comprises a first power supply and a second power supply, and the alarm module comprises a first bulb and a second bulb; through cooperation of the liquid level monitoring module, the alarm module, the wireless signal transmitter, the acousto-optic signal receiver and the acousto-optic alarm module, insufficient manpower resources of refueling and refueling ships can be made up to a certain extent, the sluggishness risk of personnel is eliminated, and meanwhile the requirements that the safety management level is urgently improved for refueling and refueling operation in Qingdao harbor districts at present are met; and the actual demand of improving the operation efficiency is met, and the process of converting safety production from human connection to internet of things is promoted.

Description

technical field [0001] The invention relates to the technical field of wireless transmission of liquid level alarm information, in particular to a wireless liquid level alarm. Background technique [0002] As we all know, pollution prevention is the top priority of the ship's oil supply and reception work. In the process of supplying and receiving oil, the oil supply pressure often rises instantaneously due to the operation error of the tanker, the unskilled operation of the personnel, the replacement of the tank, and the valve failure. It will cause the oil supply hose to rupture, the flange gasket to be damaged, and the fuel oil to overflow from the damaged hose, the damaged flange gasket or from the vent of the oil receiving vessel, causing the oil spill to enter the sea and pollute the marine environment. [0003] According to statistics, in 2021, there will be 3 oil spill pollution accidents during the refueling process of bunkering vessels in Qingdao port area, all of...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that during the oil supply and receiving process of the ship, the oil supply pressure often rises instantaneously due to the operation error of the oil receiving ship, unskilled personnel, switching tanks, valve failures, etc. At this time, if Failure to stop the pump at the refueling end in time may lead to rupture of the fuel supply hose, damage to the flange gasket, and fuel spillage from the damaged hose, flange gasket or vent hole of the tanker, causing oil to spill into the sea and pollute the sea.
