Abstract
A drilling mud outlet flow monitoring alarm consists of a liquid measuring pipe, an anti-overflowing base and a flow transducer, wherein the liquid measuring pipe is an annular pipeline which is in bolted connection with an overflowing pipe; the anti-overflowing base is a box-shaped support which is in bolted connection with the liquid measuring pipe; and the flow transducer is a sensing display which is in bolted connection with one surface of the anti-overflowing base with a circular hole. Through real-time monitoring on the liquid level and the flow of liquid in the overflowing pipe, a risk of well kick or well leakage can be found in an early stage; the drilling mud outlet flow monitoring alarm does not contact mud directly, so that a failure of a monitoring device due to dryness of the mud can be prevented; and a liquid level transducer has a display function, so that on-site monitoring of an on-site inspector can be facilitated.

Further, described flow transmitter comprises: sensor, be sonar sensor, and be fixed on housing by anti-overflow seat one side middle part; Housing is a transparent toughened glass window cube box hat, and bolt is connected on anti-overflow seat; Display circuit board is a charactron circuit board, is fixed on housing transparent toughened glass window back.Can be not malfunctioning because of the dry and hard monitoring system that causes of mud with sonar sensor, use simultaneously toughened glass window can satisfy the explosion-proof requirement of on-the-spot electrical equipment.
Further, described sensor is sonar temperature integrated transducer.Can also monitor the temperature of bleed off pipe outlet with TEMP.
Further, described display circuit board is at least two row's seven segment digital tubes, and a row shows flow, and another row shows liquid level; Any one arranges the displays temperature that can also circulate.So utilize seven segment digital tubes to show, with low cost and reliable and stable.
Further, described display circuit board is also with red LED and yellow led.LED can remind well kick or leakage risk.
Further, in the box wall of the non-circular port of usheing to seat of described anti-overflow seat, at least two opposed box walls are arranged with peep hole.Peep hole is beneficial to the liquid level situation in monitor staff's manual observation bleed off pipe.
Further, described monitoring alarm is also with a voice guard.Audible alarm can be reminded the generation of monitor staff's emergency.
The beneficial effects of the utility model are: the utility model is fixed on flow transmitter on bleed off pipe by measuring pipet, anti-overflow seat, and utilizes sonar sensor to come liquid level and flow in real-time monitoring bleed off pipe by seat circular port and amount liquid circular port; Thereby can the early detection well kick or the risk of leakage, and sonar sensor does not directly contact mud, also just can prevent the appearance of the malfunctioning situation of supervising device that causes because mud is dry and hard, the liquid level transmitter also with Presentation Function, is convenient to on-the-spot personnel's on-site supervision of making an inspection tour simultaneously.
