Description
Technical field
The present invention relates to a kind of device that liquid in storage tank in oil, chemical industry or other industry field is carried out the assay sampling, exactly a kind of integrated sampling positioning method.
Background technology
At the production run of oil, chemical industry and other industry or the storage stage of raw material and finished product, need constantly to gather wherein representative sample and carry out assay, the method of sampling is generally two kinds at present, and a kind of is artificial sample, and another kind is to sample with sampling thief.When sampling with sampling thief, need to position sampling pipe in tank, in order to obtain the medium of diverse location, at present general is a kind of accordion structure and a kind of flexible superposing type structure, accordion structure adopts one or two sampling pipe support, the one end hangs on floating plate or on floating drum, utilizes its buoyancy to pull support to rotate around stationary shaft; The sampling pipe that is fixed on support moves thereupon, thereby realizes the location of sampling pipe, and this physical dimension is large, and weight is large, installs loaded down with trivial detailsly, be subjected in tank the impact of other device larger, and the sampling degree of accuracy is inadequate.
It is telescopic that (its patent No.: ZL02208233.6) open, it is to be provided with an expansion bracket in tank, and expansion bracket is the engineer's scale linkage assembly by Chinese patent, sampling pipe is fixed in expansion bracket, this structure space is slightly little, but actual and non-homogeneous flexible, and error is still very large and install loaded down with trivial details, need tank body is transformed welding, still need certain space, and part is many, failure rate is high, manufacturing cost is high, installs, transports all inconvenient.
Summary of the invention
What the purpose of this invention is to provide is a kind of lightweight, simple in structure, and easy and widely applicable integrated sampling positioning method is installed, and can realize the accurate location of one or more sampling pipes.
The object of the present invention is achieved like this, integrated sampling positioning method, which comprises at least casing, locate little steel band, sample little steel band, locating wheel, wheel shaft, axle sleeve, constant force spring, sampling pipe, wheel shaft is horizontally fixed in casing, wheel shaft one end is connected with locating wheel by bearing; The wheel shaft other end has been fixed by socket constant force spring; Locating wheel be one with the raised wheel of round step, locate little steel band and the sampling little steel band be separately fixed on the raised wheel of different-diameter; Locate little steel band one end and stretch on the edge downwards by the perforate of bottom half, fix with tank bottom, the other end is wrapped on the large diameter wheel body of locating wheel clockwise; Little steel band one end of sampling is connected along stretching with sampling pipe downwards, and the other end is wrapped on locating wheel minor diameter wheel body clockwise.
Characteristics of the present invention are: because little steel band one end in location is fixed on tank bottom, therefore locating the torsion that little steel band overcomes with the coaxial constant force spring of locating wheel pulls locating wheel to turn clockwise, be wrapped in simultaneously on locating wheel on another diameter the little steel band of sampling discharge certain-length, the sampling flexible pipe that is fixed on the little steel band of sampling is suspended on and floating plate or the proportional assigned address of float-level height (being liquid level).
Advantage of the present invention is:
1. can be fixed on floating plate, also can be fixed on floating drum.
2. simple in structure, cost is low, and is safe and reliable.
3. take up an area the space little.
4. easy for installation, can realize without hot work.
5. adopt little steel band, effectively avoided the mutual winding problem of a plurality of sampling flexible pipes.
Description of drawings
Fig. 1 is embodiment of the present invention structural representation.
In figure: 1, casing; 2, locate little steel band; 3, the little steel band of sampling; 4, locating wheel; 5, wheel shaft; 6, axle sleeve; 7, constant force spring; 8, sampling pipe; 9, buoyancy aid.
Embodiment
The present invention will be further described below in conjunction with the embodiment accompanying drawing.
As shown in Figure 1, integrated type sampling positioner, at least comprise casing 1, the little steel band 2 in location, the little steel band 3 of sampling, locating wheel 4, wheel shaft 5, axle sleeve 6, constant force spring 7, sampling pipe 8, wheel shaft 5 is horizontally fixed in casing 1, and wheel shaft 5 one ends are connected with locating wheel 4 by bearing; Wheel shaft 5 other ends have been fixed by socket constant force spring 7; Locating wheel 4 be one with the raised wheel of round step, locate little steel band 2 and the little steel band 3 of sampling is separately fixed on the raised wheel of different-diameter; Locate the perforate of little steel band 2 one ends by casing 1 bottom downwards along stretching, fix with tank bottom, the other end is wrapped on the large diameter wheel body of locating wheel 4 clockwise; Little steel band 3 one ends of sampling are connected along stretching with sampling pipe 8 downwards, and the other end is wrapped on locating wheel 4 minor diameter wheel bodys clockwise.Casing 1 is connected and fixed with buoyancy aid 9.Buoyancy aid 9 can be floating plate or floating drum, when floating plate rises with liquid level, because little steel band 2 one ends in location are fixed on tank bottom, therefore locating the torsion that little steel band 2 overcomes with the coaxial constant force spring 7 of locating wheel 4 pulls locating wheel 4 to turn clockwise, be wrapped in simultaneously on locating wheel on another diameter the little steel band 3 of sampling discharge certain-length, the sampling flexible pipe 8 that is fixed on the little steel band 3 of sampling is suspended on and floating plate or the proportional assigned address of float-level height (being liquid level).
When floating plate descends with liquid level, locate little steel band 2 lax, this moment constant force spring 7 the torsion little steel band 2 in location that will relax and the wheel of the little steel band 3 of the sampling respective diameters separately that is wound into counterclockwise locating wheel 4 on.
According to the status requirement of sampling pipe 8, the accurate location that can realize the assigned address of sampling pipe 8 by the relative diameter size of regulating the wheel that is wound around the little steel band 3 of sampling and the little steel band 2 in location on locating wheel 4.
System is in in the storage tank of stirring apparatus the time, because little steel band has the automatic homing characteristic, will effectively avoid so the little steel band 2 in location on driving wheel to be intertwined with the little steel band 3 of sampling and sampling pipe 8 on engaged wheel, makes whole system malfunctioning.
In sum, the utility model utilizes floating plate (floating drum) lifting, the automatic homing characteristic of constant force spring storage torsion and little steel band, and the accurate location that had both solved sampling pipe has solved again the mutual winding problem between little steel band, sampling pipe simultaneously.
