Abstract
The utility model relates to a temperature measuring instrument for mud of the sea floor. The utility model comprises a vibration section and a measurement section, wherein, each eccentric wheel 6 of the vibration section is a fan-shaped structure, and a fan-shaped intersection angle of each eccentric wheel 6 is 85 DEG; a measuring head 25 of the mud temperature measuring section is provided with four mud guiding circular arcs 27 which are symmetrically distributed, and the circular arc radius of each mud guiding circular arc is 35 millimeters. The design of the utility model utilizes two low-speed DC motor to drive two eccentric wheels which are symmetrical distributed to generate vibration which has fixed frequency. Through optimization design and considering various objective factors, each eccentric wheel is made into the fan-shaped structure, the sector intersection angle is 85 DEG, and thus the vibration effect is the most ideal.
Description
Affiliated technical field
The utility model belongs to the instrument of measuring seabed mud temperature, is specifically related to the especially eccentric improvement of its mechanical part.
Background technology
The mud temperature characteristics of sea bed is grasped in offshore oil development and production requirement.Sea bed can be divided into: mud, and silt, several types such as rock, iron plate sand wherein, the temperature survey difficulty is very high under the sea bed layer of rock.Mud temperature measurement instrument system is an outfit with the ship winch, winches to the seabed with under it, measures as the degree of depth with hanger rope length, measures each layer mud temperature.The difficult point of mud temperature measurement instrument is how to make the temperature gauge head to reach certain degree of depth.In most cases, only depend on the deadweight of instrument itself to realize.The design adopts and vibrates the mode that adds counterweight, promptly obtains the expulsive force of burying of mud Wen Yi by suitable counterweight and instrument body vibration.And general mud temperature measurement instrument is in measuring process, and when gauge head goed deep into mud layer gradually, the temperature sensor of gauge head inner chamber can be subjected to undue extruding force sometimes, causes mud temperature rise to be measured, the precision that influence is measured.
Summary of the invention
The purpose of this utility model is to provide a kind of seabed mud temperature measurement instrument accurately simple in structure, that cost is low of measuring for addressing the above problem.
For the utility model that achieves the above object is a kind of seabed mud temperature measurement instrument of realizing like this, involving vibrations drive part and measure portion, described vibratory drive partly comprises: direct current generator, register pin eccentric wheel and respective housings; Measure portion comprises: measuring staff, gauge head, temperature sensor circuit plate and signal transmssion line; The eccentric wheel of vibratory drive part is a sector structure; What have four symmetrical distributions on the gauge head of mud temperature measurement part leads the mud circular arc.
Eccentric covering of the fan angle is 85 degree.
The arc radius of leading the mud circular arc is 35 millimeters.
Advantage of the present utility model and good effect are that the vibration that the design adopts the eccentric wheel of two symmetrical distributions of low-speed DC driven by motor to produce fixed frequency realizes.The eccentric wheel of most of existing measuring instrument all is to decide by rule of thumb, can not reach best vibrating effect.The utility model is considered various objective factors through optimal design, and eccentric wheel is made sector structure, covering of the fan angle 85 degree, and the vibrating effect of this moment is the most desirable.The utility model is in order to guarantee the thermal conductive resin of gauge head simultaneously, and the gauge head material adopts brass.Simultaneously lead the mud arc four of gauge head upper design, when gauge head goed deep into mud layer gradually, the silt of gauge head front portion will be discharged by leading the mud arc, has fallen at the end extruding force of silt to temperature sensor greatly, mud temperature to be measured just can not be subjected to big influence, and the precision of measurement has also improved greatly.
