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

Steel cable floating ball type whole-sampling device for crude oil storage tank

Technical field

The invention belongs to the fluid sampling device technical field, relate to a kind of steel cable floating ball type whole-sampling device for crude oil storage tank.

Background technology

At present, the method of the liquid in storage tank sampling that people adopt is to stipulate according to GB/T4756-1998, use sampling transfusion bottle or other devices to take out required sample from tank top, this sampling method not only takes a lot of work, time-consuming, interference from human factor is large, and the sampling personnel are when upper tank, easily slidingly fall or suck excessive harmful gas, exist potential safety hazard.Sampler under the tank newly developed though solved safety problem, was restricted by self structure in recent years, made 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 defects, through constantly analyzing design, technical matters to be solved by this invention provides a kind of steel cable floating ball type whole-sampling device for crude oil storage tank, 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 solution used in the present invention is that this steel cable floating ball type whole-sampling device for crude oil storage tank comprises cable wire ball float positioning system, power system and setting-out system, described ball float positioning system is to set up positioning rotating shaft separately and twine the cable wire cylinder at storage tank tank body inner bottom part, be connected with the rotation cable wire at positioning rotating shaft, twining winding winding cable wire on the cable wire cylinder, ball float is established in rotation cable wire and winding cable wire contact position; Described 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, establishes controller by reductor; Described setting-out system is at tank body peripheral hardware ebullator, ebullator one end is connected with T-way change-over solenoid valve, the other end is connected with the flexible fixedly communicating pipe of passing tank wall, and flexible fixedly communicating pipe is connected by the rotation catheter that positioning rotating shaft and extension apply on the rotation cable wire.

The present invention adopts the designed steel cable floating ball type whole-sampling device for crude oil storage tank of technique scheme, rotation by reductor, drive transmission shaft and twine the cable wire cylinder and rotate, ball float will twine cable wire and further under the effect of buoyancy, 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 to steel cable floating ball type whole-sampling device for crude oil storage tank of the present invention.

Referring to Fig. 1 to Fig. 6, the structure of steel cable floating ball type whole-sampling device for crude oil storage tank of the present invention comprises cable wire ball float positioning system, power system and setting-out system, the ball float positioning system is to set firmly respectively positioning rotating shaft 4 and twine cable wire cylinder 7 at storage tank tank body 14 inner bottom parts, be connected with rotation cable wire 2 at positioning rotating shaft 4, twining winding winding cable wire 3 on the cable wire cylinder 7, ball float 1 is established in rotation cable wire 2 and 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 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 T-way change-over solenoid 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 by 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 according to programmed instruction, T-way change-over solenoid valve 11 commutations, during reductor 9 forward rotation, the angle of its rotation is passed to by 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 the effect of ball float 1 buoyancy, make rotation cable wire 2 centered by positioning rotating shaft 4, produce accordingly rotation and drive and hang the identical rotation of rotation catheter 5 generations of applying on rotation cable wire 2, rotate catheter 5 open-ended with relative positions tank body 14 bottoms be the function that rotates the rotational angle of catheter 5, be that the angle that reductor 9 rotates has functional relation with rotation catheter 5 open-ended height (at the bottom of the relative tank), angle (rotary encoder) by 9 rotations of control reductor, can make and rotate catheter 5 open-ended be parked in arbitrarily position (relatively at the bottom of the tanks), rotating catheter 5 makes the liquid of arbitrary height in the tank link to each other with tank body 14 ebullator 10 outward by flexible fixedly communicating pipe 6, start ebullator 10, can obtain the liquor sample of arbitrary height.

The present invention in use; sampling height value by the DY400C text display input requirements on the controller 13; press " sampling " button on controller 13 panels; reductor 9 rotates and drives winding cable wire cylinder 7 by transmission shaft 8; twining cable wire 3 is released; under ball float 1 buoyancy; rotation cable wire 2 rotates and drives extension and applies in the identical rotation of rotation catheter 5 generations of rotating on the cable wire 2 take positioning rotating shaft 4 as the center of circle; controller 13 receives the output signal of rotary encoder 12; calculate at any time and rotate the open-ended relative position with at the bottom of the tank 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; after 5 seconds, automatically connect T-way change-over solenoid valve 11 setting-outs; when sample size reaches requirement by " shutdown " button on controller 13 panels; T-way change-over solenoid valve 11 outages; simultaneously ebullator 10 stalls are finished once to the liquid sampling in the tank body 14.
