Fig. 2 is the longitudinal sectional view of the present invention.
Fig. 3 is the structural schematic diagram of capillary of the present invention and liquid cabin interconnecting piece.
Fig. 4 is the structural schematic diagram that hollow plastic pipe of the present invention passes through liquid cabin.
Specific implementation mode
As depicted in figs. 1 and 2, differential depth of mud tester of the invention includes mainly:Semi-enclosed shell 10, liquid
Body storehouse 4, capillary 5, differential pressure pickup 6, data processing equipment 3, display unit 1 and for electric installation 2.
Wherein, the upper interval setting along its length of liquid cabin 4, between capillary 5 connects liquid cabin, differential pressure pickup 6
In on capillary, for measuring capillary overpressure.Data processing equipment 3, which is set to, to be installed in shell and and differential pressure pickup
Electrical connection, display unit 1 be electrically connected with the data processing equipment, and for electric installation 2 is above-mentioned part or all of Denso
Set power supply.
In this embodiment, liquid cabin has certain interval, when it is located in different liquid or colloid, between
Pressure difference can change, if pressure difference numerical value is more than set threshold value, then it is assumed that reach mud and cement colloid
Interface, to remind engineers and technicians.It is at this time the depth of mud to the distance of lower section liquid cabin from liquid level.Therefore,
The present invention is more accurate than the prior art, and operates also very simple.
In a further embodiment, normal fortune of the pressure without influencing instrument can be provided for guarantee mud and cement colloid
Row, the liquid cabin laterally have open ports, upper and lower ends sealing.According to existing engineering situation, between liquid cabin between
Away from being 0.8 to 1.2 meter, within this range, the distance needed for practical measurement can be met and larger pressure difference is provided.It needs
It is bright, it is fathomed and the density of mud and colloid according to required, adjusts the spacing of liquid cabin, be allowed to have in different solutions
There is more apparent pressure change.
In a further embodiment, in order to realize that the accurate measurement of pressure difference, the capillary are provided at both ends with rubber
It film 8 and extends in two liquid cabins, the sheet rubber 8 is closely connect by a rubber ring 7 with inner walls.Meanwhile in order to
Measuring accuracy is improved, injects hydraulic oil in capillary.Pressure is transmitted to by the solution into liquid cabin by the sheet rubber 8 of sealing
Capillary, and then generate pressure difference and incuded by differential pressure pickup and transmit.
In a still further embodiment, for timely processing information, testing efficiency is improved, tester further includes being connected to
Signal amplifying apparatus between differential pressure pickup and data processing equipment and A/D converter.Its mould for transmitting differential pressure pickup
Quasi- signal is amplified, and is converted to digital signal, is handled and is obtained the pressure difference of liquid in upper and lower liquid cabin.
In a still further embodiment, further include the warning lamp for being installed on shell and being connect with data processing equipment signal
And jingle bell.
To prevent the insufficient situation of power supply volume, the normal work of instrument is influenced, described for electric installation includes accumulator
And AC power.When extraneous unpowered or extraneous power supply are interrupted suddenly, accumulator can provide power supply for instrument, ensure instrument just
Often work.
The differential pressure pickup is connect by data line with data processing equipment, and the modeling of airtight connection is provided in liquid cabin
Expects pipe 9, the data line are passed through from plastic tube 9.
In use, enter the formation pressure of upper and lower liquid cabin using mud and cement colloid, by sheet rubber by this pressure
Power passes to the hydraulic oil in capillary, so that differential pressure pickup sensed pressure difference and transmission of analogue signal, host will press
The analog signal that gap sensor transmits is amplified, and is converted to digital signal, is handled and is obtained the pressure of liquid in upper and lower liquid cabin
Force difference numerical value, and shown in suggestion device.
When the equipment reaches the interface of mud and cement colloid, which will produce mutation, be more than set
Threshold value, suggestion device will send out alerting signal.The present invention is easy to operate, and test speed is fast, and reliability is high, can accurately measure
Depth of mud simultaneously reminds construction personnel in time, ensures construction quality, saves economic cost.
