Abstract
The utility model discloses an offshore drilling cabin bottom water position alarm device, including installing the level sensor in the floor lower part of pump house bilge pump position, install at bottom of a ship's hold pump control system incasement threshold control ware, install the audible -visual annunciator on the pump house wall, level sensor's output and threshold control ware are connected, and the output and the audible -visual annunciator of threshold control ware are connected, level sensor and 24V DC power supply are connected, and audible -visual annunciator is connected with the 220V alternating current. The utility model discloses a noncontacting proximity sensor does not contact with measurement medium, and the life -span is not improved greatly, and full digital control mode precision is high, arbitrary adjustment between alert area, and the liquid level is reported to the police under the suitable various conditions, has spreading value.
Description
Technical field
This utility model relates to high accuracy number liquid level warning field, particularly relates to a kind of offshore drilling ship alarm for water level at boat bottom.
Background technology
In prior art, the water-level alarm in offshore drilling cabin bottom portion is generally adopted floating ball type liquid level alarm, although floating ball type liquid level alarm controls simple, but poor reliability, it is especially used in drilling platforms will soon be lost efficacy by sea water, mud corrosion, particularly floating ball type liquid-level meter is subject to installation site, it has not been convenient to adjust alert locations.
Utility model content
The purpose of this utility model is to solve the shortcoming existed in prior art, and a kind of offshore drilling ship alarm for water level at boat bottom proposed.
To achieve these goals, this utility model adopts the technical scheme that
A kind of offshore drilling ship alarm for water level at boat bottom, including the liquid level sensor of the bottom, floor being arranged on pump house burr pump position, is arranged on threshold controller in burr pump control chamber, is arranged on the audible-visual annunciator on pump house wall；
The outfan of liquid level sensor is connected with threshold controller, and the outfan of threshold controller is connected with audible-visual annunciator；Liquid level sensor is connected with 24V DC source, and audible-visual annunciator is connected with 220V alternating current.
Further, described liquid level sensor adopts flame-proof type ultrasonic liquid level sensor, and range is 0.25-5m, supply voltage 24VDC, exports electric current 4-20mA.
Further, described threshold controller is MSAU controller, and power supply is 24VDC, inputs 4-20mA current signal.
Further, described audible-visual annunciator is 220V audible-visual annunciator.
Compared with prior art the beneficial effects of the utility model are: this utility model adopts noncontacting proximity sensor, does not contact with measured medium, and the life-span is greatly improved, totally digitized control mode precision is high, reporting to the police, interval is any to be adjusted, and is suitable for liquid level warning under various conditions, has promotional value.
Accompanying drawing explanation
Fig. 1 is the electrical block diagram of offshore drilling ship alarm for water level at boat bottom of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.
Referring to shown in Fig. 1, the alarm device of the present embodiment includes liquid level sensor 1, threshold controller 2 and audible-visual annunciator 3, and the outfan of liquid level sensor 1 is connected with threshold controller 2, and the outfan of threshold controller 2 is connected with audible-visual annunciator 3；Liquid level sensor 1 is connected with 24V DC source, and audible-visual annunciator 3 is connected with 220V alternating current.
Liquid level sensor 1 adopts flame-proof type ultrasonic liquid level sensor, being adopt drill ship liquid level alarm, range is 0.25-5m, and model is YD20J3TQ, supply voltage 24VDC, output electric current 4-20mA, owing to adopting contactless installation, will not touch measurement medium, so having precision height, the advantages such as reaction is fast, and power consumption is few, corrosion-resistant.
Threshold controller 2 is the MSAU controller of CMR Company, power supply is 24VDC, inputs 4-20mA current signal, can set that working value by regulating threshold value knob, and there is input abnormal signal warning function, all can export warning when level sensor fault or broken string.
What audible-visual annunciator 3 adopted is 220V audible-visual annunciator, and model is DWJ-8.Liquid level sensor needs 24VDC to power, and 24VDC power supply is to leave power supply after former small charger tears machine open.
Wherein, liquid level sensor 1 is arranged on bottom, floor, pump house burr pump position, and threshold controller 2 is installed in burr pump control chamber, and audible-visual annunciator 3 is arranged on pump house wall.
First liquid level sensor is configured after energising, pin " 4 " and " 20 " key simultaneously, until the option to be adjusted occurs, lowest order is arranged to 4mA, then adopts the mode blocked, arranging highest order is 20mA, notice that liquid level sensor has the blind area of 0.25m, when regulable control device, block liquid level sensor needing the position (0.3m place) reported to the police, then threshold value knob is regulated until controller action sends warning, by repetition test view result and sensitivity.
This utility model adopts noncontacting proximity sensor, does not contact with measured medium, and the life-span is greatly improved, and totally digitized control mode precision is high, and interval of reporting to the police arbitrarily adjusts, and is suitable for liquid level warning under various conditions, has promotional value.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive according to the technical solution of the utility model and utility model thereof and be equal to replacement or change, all should be encompassed within protection domain of the present utility model.
