The device is mainly applied to the sampling of liquid in the storage tank, and is mainly characterized in that: a steel cable floating ball positioning system is arranged in a storage tank body; and a power system and a lofting system are arranged outside the storage tank body. By the steel cable floating ball type whole-sampling device for the crude oil storage tank, different positions in the tank body can be sampled to realize the whole sampling of the crude oil storage tank, sampling is quick and convenient and sampling density can be theoretically infinite.

Description

Cable wire float-ball type crude oil storage tank holostrome sampler

Technical field

The invention belongs to the fluid sampling device technical field, relate to a kind of cable wire float-ball type crude oil storage tank holostrome sampler.

Background technology

At present; The method of the liquid in storage tank sampling that people adopt is according to the GB/T4756-1998 regulation, uses sampling transfusion bottle or other devices to take out required sample from tank top, and this sampling method not only takes a lot of work, time-consuming; Interference from human factor is big; And the sampling personnel are when last jar, slidingly easily fall or suck excessive harmful gas, exist potential safety hazard.Jar newly developed in recent years is ST down, though solved safety problem, restricted by self structure, makes its sampling density far can't satisfy the sampling requirement of the non-homogeneous liquid of crude oil class.

Summary of the invention

The inventor finds that the liquid in storage tank sampling method that existing people adopt exists above-mentioned defective; Through constantly analyzing design; Technical matters to be solved by this invention provides a kind of cable wire float-ball type crude oil storage tank holostrome sampler; Utilize this device to take a sample to liquid in storage tank quickly and easily, and sampling density can be infinity in theory.

For solving the problems of the technologies described above; The technical scheme that the present invention taked is that this cable wire float-ball type crude oil storage tank holostrome sampler comprises cable wire ball float positioning system; Power system and setting-out system, said ball float positioning system set up positioning rotating shaft separately and twine the cable wire cylinder at storage tank tank body inner bottom part, on positioning rotating shaft, are connected with the rotation cable wire; Twining winding winding cable wire on the cable wire cylinder, the rotation cable wire is established ball float with winding cable wire contact position; Said power system is at tank body peripheral hardware reductor, and at the output shaft of reductor and twine between the cable wire cylinder and establish the transmission shaft that passes tank wall, rotary encoder is connected with reductor, by reductor, establishes controller; Said setting-out system is at tank body peripheral hardware ebullator; Ebullator one end is connected with the electromagnetism three-way diverter valve; The other end is connected with the flexible fixedly communicating pipe of passing tank wall, and flexible fixedly communicating pipe is connected through the rotation catheter that positioning rotating shaft and extension apply on the rotation cable wire.

The cable wire float-ball type crude oil storage tank holostrome sampler that the present invention adopts technique scheme to design through the rotation of reductor, drives transmission shaft and twines the rotation of cable wire cylinder; Ball float will twine cable wire and further under buoyancy function; The rotation catheter that extension applies on the rotation cable wire rotates with ball float, thereby can take a sample to the diverse location in the tank body, realizes the crude oil storage tank holostrome is taken a sample; Not only sampling is quick, convenient, and its sampling density can be infinity in theory.

Embodiment

Specify below in conjunction with the structure of accompanying drawing cable wire float-ball type crude oil storage tank holostrome sampler of the present invention.

Referring to Fig. 1 to Fig. 6; The structure of cable wire float-ball type crude oil storage tank holostrome sampler of the present invention comprises cable wire ball float positioning system; Power system and setting-out system, ball float positioning system set firmly positioning rotating shaft 4 respectively and twine cable wire cylinder 7 at storage tank tank body 14 inner bottom parts, on positioning rotating shaft 4, are connected with rotation cable wire 2; Twining winding winding cable wire 3 on the cable wire cylinder 7, rotation cable wire 2 is established ball float 1 with winding cable wire 3 contact positions.Power system is at tank body 14 peripheral hardware reductors 9, establishes the transmission shaft 8 that passes tank body 14 walls at the output shaft and 7 on the winding cable wire cylinder of reductor 9, and rotary encoder 12 is connected with reductor 9, at the reductor 9 other controllers 13 of establishing.The setting-out system is at tank body 14 peripheral hardware ebullators 10; Ebullator 10 1 ends are connected with electromagnetism three-way diverter valve 11; The other end is connected with the flexible fixedly communicating pipe 6 of passing tank body 14 walls, and flexible fixedly communicating pipe 6 is connected through the rotation catheter 5 that positioning rotating shaft 4 and extension apply on rotation cable wire 2.

Controller 13 of the present invention receives the signal of rotary encoder 12; Start or

stop ebullator

10,11 switching-overs of electromagnetism three-way diverter valve according to programmed instruction; During reductor 9 forward rotation; The angle of its rotation is passed to through transmission shaft 8 and is twined cable wire cylinder 7, the winding cable wire 3 that is wrapped on the winding cable wire cylinder 7 is discharged accordingly, under ball float 1 buoyancy function; Making rotation cable wire 2 is that the center produces rotation accordingly and the identical rotation of rotation catheter 5 generations of applying on rotation cable wire 2 is hung in drive with positioning rotating shaft 4; Rotate catheter 5 open-ended with relative positions tank body 14 bottoms be the function that rotates the rotational angle of catheter 5, promptly reductor 9 angle of rotating has functional relation with rotating catheter 5 open-ended height (jar end relatively), the angle (rotary encoder) of rotating through control reductor 9; Can make and rotate the catheter 5 open-ended positions (jar end relatively) arbitrarily that are parked in; Rotate catheter 5 liquid of arbitrary height in the jar is linked to each other with tank body 14 outer ebullators 10, start ebullator 10, can obtain the liquor sample of arbitrary height.

The present invention through the sampling height value that the input of the DY400C text display on the controller 13 requires, presses " sampling " button on controller 13 panels in use; Reductor 9 rotates and drives winding cable wire cylinder 7 through transmission shaft 8, twines cable wire 3 and is released, under ball float 1 buoyancy; Rotation cable wire 2 is that the rotation catheter 5 that rotate in the center of circle and the drive extension applies on rotation cable wire 2 produces identical rotation with positioning rotating shaft 4; Controller 13 receives the output signal of rotary encoders 12, calculates at any time to rotate the open-ended relative position with jar end of catheter 5, when reaching the sampling height of setting; Automatically stop reductor 9 and rotate and light " allowing sampling " lamp; Press " sampling " button on controller 13 panels this moment, controller 13 starts ebullator 10 automatically, treats to connect 11 setting-outs of electromagnetism three-way diverter valve automatically after 5 seconds; When sample size reaches requirement by " shutdown " button on controller 13 panels; 11 outages of electromagnetism three-way diverter valve, ebullator 10 stalls are simultaneously accomplished once to the liquid sampling in the tank body 14.
