Abstract
The invention discloses an automatic sample replacing device which comprises a hollow spherical casing. The automatic sample replacing device is characterized in that at least two sampling ports communicated with an inner chamber of the casing are formed on the casing; a rotatable hemispherical switcher and a driving device capable of driving the switcher to rotate around an axial line of the switcher are arranged in the inner chamber of the casing; sampling tubes are arranged in the switcher; and one end of each sampling tube can be connected with one sampling port, and the other end can extend out of the casing along the rotation axial line of the switcher. According to the automatic sample replacing device, the plurality of sampling ports are switched automatically through a stepping motor, so that the purpose of sampling various liquids or gases can be achieved. The automatic sample replacing device provided by the invention has the advantages of simple structure, easiness in use, high efficiency and the like.
Description
Technical field
The present invention relates to a kind of sampler that is used for environment measuring.
Background technology
At present, the mode that can only change manually for the sampling operation of a plurality of gases or fluid sample in the environmental monitoring.This mode though can handle multiple emergency case, because the sampling time is long, needs the wait long period just to need to switch, and this can waste a large amount of human resources and time.
Summary of the invention
The invention provides a kind of solution of the above problems, provide a kind of simple in structure, easy-to-use, vary device automatically efficiently.
Technical scheme of the present invention provides a kind of device that varies automatically; It comprises the spherical housing of hollow; It is characterized in that: said shell is provided with at least two sample taps that are communicated with said shell inner cavity; Be provided with rotatable hemispheric switch in the said shell inner cavity and drive the drive unit of said switch around himself axis rotation; One stopple coupon is set in the said switch, and said stopple coupon one end can connect said sample tap, and the other end reaches the outside of said shell along the rotation of said switch.
Preferably, said drive unit is the stepper motor that is installed on the said outer casing inner wall, and the rotating shaft of said stepper motor connects said switch.
Preferably, said switch is provided with spline, the rotating shaft of said stepper motor be provided with can with the spline of said spline coupling.
Preferably, said sample tap connects stopple coupon outward.
Automatically the device that varies of the present invention is through being switched between a plurality of sample taps by stepper motor automatically, thereby realizes the operation of taking a sample of various liquid or gas.Automatically the device that varies of the present invention has advantages such as simple in structure, easy-to-use, efficient.

Embodiment
Following specific embodiments of the invention is described in further detail.
Extremely shown in Figure 4 like Fig. 1; A kind of spherical housing 10 that device comprises hollow that varies automatically of the present invention; Shell 10 is provided with at least two sample taps (not shown) that are communicated with shell 10 inner chambers, and sample tap connects stopple coupon 12 outward, and each stopple coupon 12 can connect different sampling objects respectively.
Be provided with rotatable hemispheric switch 14 in shell 10 inner chambers and drive the drive unit 16 of switch 14 around himself axis rotation.Drive unit 16 in the preferred embodiment of the present invention is for being installed in the stepper motor 18 on shell 10 inwalls, and the rotating shaft of stepper motor 18 connects switch 14.Switch 14 is provided with spline 20, the rotating shaft 22 of stepper motor 18 be provided with can with the spline 24 of spline 20 coupling.The modes such as motor-driven leading screw that the industry of also can sampling is often used drive switch 14 rotations.
One stopple coupon 12 is set in the switch 14, and stopple coupon 12 1 ends can connect sample tap, and the other end reaches outside, joint detection or the gathering-device of shell 10 along the rotation of switch 14.Thereby so just can make stopple coupon 12 1 ends connect different sample taps, thereby realize switching different sample objects through rotation switch 14.
Above embodiment is merely the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
