Abstract
The invention discloses a sampling device with the functions of liquid level detection and automatic emptying. The sampling device is provided with a cup body for containing liquid to be detected and a cup cover which is fit closely and covers the cup cover of the cup body; at least one water inlet hole is arranged above the side wall of the cup body; the water inlet hole is communicated with a water inlet pipe; at least one overflow hole is correspondingly arranged above the other side wall of the cup body; the overflow hole is communicated with an overflow pipe; at least one sampling hole is arranged below the side wall of the cup body and each sampling hole is communicated with a sampling pipe correspondingly; the middle-bottom part of the cup body is also provided with at least one automatic emptying hole; the emptying hole is connected with an emptying pipe which is controlled for opening and closing by an electromagnetic valve; and the cup cover has a liquid level monitoring device which can automatically detect that whether the liquid to be detected in the sampling cup is full. The device has the functions of liquid level detection and automatic emptying, thus ensuring the accuracy and representation of sampling water.
Description
Technical field
What the present invention relates to mechanical field joins the sample container, specifically is meant a kind of with the Level Detection and the sample storage device of emptying automatically.
Background technology
At present, known compounding device is made up of sampling cup, conveyance conduit, utilizes small-sized supercharge pump that fluid to be measured is pumped in the sampling cup, and excess liquid overflow from sampling cup is gone out, thereby implements for autoanalyzer analytical sampling test.
Traditional storage device does not have level monitoring device, whether the fluid to be measured in the sampling cup is filled with, unknown, thereby can't notify or system for prompting is made further work, if supercharge pump breaks down in the time of can't carrying liquid, because sampling cup can't obtain liquid, thereby in the back during the automatic analytical instrument test of link, then may cause fault.
On the other hand, because long stored sample, the inwall of sampling cup can be because of the complicated ingredient or the stronger absorption of the suspension in the liquid of sample, and make the inwall dirt, and grow algae or bacterium, and then influence last measurement result.
Summary of the invention
In order to overcome the problem that in joining the sample process, can not detect liquid level in the sampling cup, and guarantee the automatically emptying after instrument test is finished of test solution physical efficiency, do not pollute inwall, reduce and safeguard, the invention provides a kind of sample storage device, not only can directly observe the internal liquid situation, and have the function of automatic emptying and band Level Detection by well-illuminated housing.
For achieving the above object, the present invention is achieved by the following technical programs: the sampling apparatus of band Level Detection and emptying automatically has the cup that holds fluid to be measured, and and the identical bowl cover that also can cover cup of described cup, has at least one inlet opening in the top position of described cup sidewall, this inlet opening and water inlet pipe communicate, correspondence is equipped with at least one spillway hole in the top position of described another sidewall of cup, this spillway hole and overflow pipe are connected, described cup sidewall below has at least one thieff hatch, and each thieff hatch and sampling pipe are connected accordingly, the middle bottom of described cup also has at least one automatic drain hole, this drain hole is connected to the evacuated tube that is opened and closed by solenoid control, and described bowl cover has can detect the level monitoring device whether fluid to be measured in the sampling cup is filled with automatically.
Described level monitoring device is a liquid level sensor.
Compared with prior art; the present invention has following substantive distinguishing features and progress: novel structure; reasonable in design, have the function of liquid in automatic detection of internal tank liquid level and the automatic emptying receptacles, can be used as the accurate automatic analytical instrument of protection and use with the sample container of joining that hangs down maintenance.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1;
Fig. 3 is the vertical view of cup;
Fig. 4 is the vertical view of bowl cover.
Among the figure: 1, cup, 2, bowl cover, 3, the inlet opening, 4, water inlet pipe, 5, spillway hole, 6, overflow pipe, 7, thieff hatch, 8, sampling pipe, 9, drain hole, 10, evacuated tube, 11, solenoid valve, 12, liquid level sensor.
Embodiment
With reference to Fig. 1-shown in Figure 4, apparatus of the present invention are the well-illuminated similar goblet of sealing, it comprises the cup 1 that is used to put sample water, bowl cover 2 with the identical sealing of cup cup, place, side top in cup 1 is provided with the inlet opening 3 that is communicated with water inlet pipe 4, water inlet pipe 4 connects booster water pump, place, cup 1 opposite side top is provided with the spillway hole 5 that overflows automatically when making sample water arrive the liquid level index accordingly, these spillway hole 5 corresponding and overflow pipe 6 connections, the place, below of the cup left and right sides has the thieff hatch 7 of two symmetries, each thieff hatch 7 is connected with sampling pipe 8 accordingly, the middle part, the end of cup 1 has automatic drain hole 9, drain hole 9 is connected to evacuated tube 10, described evacuated tube 10 is opened by solenoid valve 11 controls, closed, middle part on the bowl cover 2 has detects the level gauge that whether detected sample water is filled with in the sampling cup, and this level gauge adopts liquid level sensor 12.
The present invention is in joining the sample process, at first sample water is pumped in the sampling cup by water inlet pipe 4, inlet opening 3 by booster water pump, whether sample water is filled in the liquid level sensor 12 monitoring cups on the bowl cover 2, fill as sample water and to touch sensor 12,12 automatic cutouts of sensor are closed sample water and are flowed into, otherwise closure makes it continue to flow into cup 1, and unnecessary sample water goes out by overflow pipe 6 overflows from spillway hole 5 simultaneously, realizes the automatic measuring ability of liquid level; Solenoid valve 11 on the evacuated tube 10 is normally closed, after finishing, sample water analytical sampling test opens evacuated tube 10 by solenoid valve 11, make the automatic emptying of suspension in sample water residual in the sampling cup and impurity component or the liquid, thereby guarantee the accuracy and the representativeness of sampling.
Above content is in conjunction with further describing that concrete main embodiment is done, and can not assert that concrete enforcement of the present invention is confined to these explanations.Those skilled in the art without departing from the inventive concept of the premise, some other technology of done accurately, the deduction or replace that beautify, all should belong to protection scope of the present invention.
