Description
Technical field
The utility model relates to a kind of device that liquid in the storage tank in oil, chemical industry or other industry field is carried out the assay sampling, exactly a kind of integrated form sampling steady arm.
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 in jar, position sampling pipe, so that 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 the floating plate or on the floating drum, utilizes its buoyancy pulling support to rotate around stationary shaft; The sampling pipe that is fixed on the support moves thereupon, thus the location of realizing sampling pipe, this physical dimension is big, and weight is big, installs loaded down with trivial detailsly, be subjected to jar influence of interior other device bigger, and the degree of accuracy of sampling is not enough.
It is telescopic that (its patent No.: ZL02208233.6) open, it is to be provided with an expansion bracket in jar, and expansion bracket is the engineer's scale linkage assembly by Chinese patent, sampling pipe is fixed in the expansion bracket, this structure space is slightly little, but actual and non-homogeneous flexible, error is still very big and install loaded down with trivial details, need tank body is transformed welding, still need certain space, and part is many, the failure rate height, the manufacturing cost height is installed, transports all inconvenient.
Summary of the invention
What the purpose of this utility model provided is a kind of in light weight, simple in structure, easy and widely applicable integrated form sampling steady arm is installed, the accurate location that can realize one or more sampling pipes.
The purpose of this utility model is to realize like this, integrated form sampling steady arm, 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 the casing, wheel shaft one end is connected with locating wheel by bearing; The socket of the wheel shaft other end is fixed with constant force spring; Locating wheel is a raised wheel with round step, locatees little steel band and is separately fixed on the raised wheel of different-diameter with the little steel band of sampling; Locate little steel band one end and stretch to the lower edge 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 stretched with sampling pipe to the lower edge and is connected, and the other end is wrapped on the locating wheel minor diameter wheel body clockwise.
Characteristics of the present utility model are: because little steel band one end in location is fixed on tank bottom, therefore locating the torsion pulling locating wheel that little steel band overcomes with the coaxial constant force spring of locating wheel turns clockwise, be wrapped in simultaneously on the 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).
The utility model has the advantages that:
1. can be fixed on the floating plate, also can be fixed on the floating drum.
2. simple in structure, cost is low, and is safe and reliable.
3. it is little to take up an area of the space.
4. easy for installation, can realize the installation of not getting angry.
5. adopt little steel band, effectively avoided the mutual winding problem of a plurality of sampling flexible pipes.
Description of drawings
Fig. 1 is the utility model example structure synoptic diagram.
Among the 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
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, integrated form sampling steady arm, 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 the casing 1, and wheel shaft 5 one ends are connected with locating wheel 4 by bearing; Wheel shaft 5 other end sockets are fixed with constant force spring 7; Locating wheel 4 is the raised wheels with round step, locatees little steel band 2 and is separately fixed on the raised wheel of different-diameter with the little steel band 3 of sampling; Locate little steel band 2 one ends and stretch to the lower edge by the perforate of casing 1 bottom, fix with tank bottom, the other end is wrapped on the locating wheel 4 large diameter wheel bodys clockwise; Little steel band 3 one ends of sampling are stretched with sampling pipe 8 to the lower edge and are connected, and the other end is wrapped on the 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 pulling locating wheel 4 that little steel band 2 overcomes with the coaxial constant force spring 7 of locating wheel 4 turns clockwise, be wrapped in simultaneously on the 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 descended with liquid level, it was lax to locate little steel band 2, 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 locating wheel 4 counterclockwise 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 twines little steel band 3 of sampling and the little steel band 2 in location on the locating wheel 4.
When system is in the storage tank that has stirring apparatus,, will effectively avoid the little steel band 2 in location on the driving wheel to be intertwined like this, make total system malfunctioning with little steel band 3 of sampling and sampling pipe 8 on the engaged wheel because little steel band has the automatic homing characteristic.
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 the mutual winding problem between little steel band, the sampling pipe simultaneously again.
