Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further, the embodiment of the utility model includes but not limited to the following example.
Embodiment 1
Shown in Fig. 1, bracing frame 1 is made up of interconnective vertical installing plate of an end and horizontal supporting plate; Propulsion system as preferred selection motor 6, are installed on the horizontal supporting plate of bracing frame 1; Slide block guide rail 15 is installed on vertical installing plate, and master slider 3 is slidingly connected on the slide block guide rail 15 with secondary slide block 2; Main support 13 and assistant support 11 be by vertical and interconnected vertical plate of an end and leveling board formation each other, and the vertical plate of main support 13 is fixed on the master slider 3, and the vertical plate of assistant support 11 is fixed on the secondary slide block 2, and the leveling board of the two then is parallel to each other; Sleeve 14 all is fixed on the main support 13 with the lower end of puncture sampling probe 12; And sleeve 14 upper ends are passed assistant support 11 and are extended to assistant support 11 tops; On the sleeve above the assistant support 11 14, also be provided with sleeve stop nut 10; Rotating shaft 9 upper ends are connected with propulsion system, and the lower end is then passed sleeve 14 and extended to main support 13 belows; And, on the sleeve 14 between main support 13 and the assistant support 11 sleeve spring 4 is installed also; Puncture sampling probe 12 also is provided with the through hole that supplies puncture sampling probe 12 to pass on the assistant support 11 of position, its horizontal supporting plate over against the position is provided with sample storage container mount pad 7, and the container 8 of sample is housed in order to installation.
The implementation procedure of the utility model is following:
As shown in Figure 2, during sampling, at first starter motor rotates rotating shaft 9, and the rotation of rotating shaft 9 will make the sleeve 14 that is threaded with it rise, because the sleeve lower end is fixed on the main support 13, therefore, main support 13 also will move upward; And the rising of main support at first must drive puncture sampling probe 12 to move up, and simultaneously, the sleeve spring 4 on the sleeve will be compressed, if the elastic force that makes progress that this moment, sleeve spring 4 produced because of compression is less than the gravity of assistant support 11, then assistant support does not move on temporarily not understanding.Along with main support moves on continuing, sleeve spring 4 is by further compression, when the elastic force of its generation during greater than the gravity of assistant support 11, moves on assistant support 11 begins.When moving on to sleeve stop nut 10 places on the assistant support 11, on stopping, moving assistant support.Safety for the container 8 that guarantees to store sample; Generally speaking; The horizontal level of sleeve stop nut 10 should be lower than container 8 horizontal level bottom of storage sample, so time puncture sampling probe 12 does not also pass the through hole on the assistant support and lunges in the container 8 of storage sample.
, moves by main support on continuing; After puncture sampling probe 12 passes the through hole on the assistant support 11 and thrusts the container 8 of storage sample, begin sampling from container 8, at this moment; Only need be connected with conduit, can sample delivery in the container 8 be gone out in the lower end of puncture sampling probe 12.
Sampling makes the motor backward rotation after accomplishing, and main support 13 will begin to descend, and puncture sampling probe 12 also descends thereupon; At this moment, because the elastic force that makes progress that sleeve spring 4 produces is still greater than the gravity of assistant support 11, so assistant support 11 does not descend.When main support drops to a certain degree; When making sleeve spring 4 return to natural length, its downward pressure that bears just in time equals the gravity of assistant support, at this moment; Assistant support begins to descend with main support; All drop to the original position up to main support, assistant support, puncture sampling probe 12 also spins off from assistant support, and gets back to the original position.Disable motor, whole sampling and recuperation finish.
Based on above-mentioned principle of work, the utility model can be according to the structure shown in Fig. 1 or 2, at sleeve 14 set inside screw threads, cooperatively interacts through rotating shaft 9 and screw thread on the sleeve 14 and to realize the action of entire mechanism.
As shown in Figure 3, on the basis of embodiment 1, we also can fix a feed screw nut 5 between main support 13 and sleeve 14, cooperatively interact through the screw thread in this feed screw nut 5 and the rotating shaft 9, realize the action of entire mechanism.Because dual mode only is that the parts that cooperate are slightly different, other structures are all identical with the course of work, therefore, no longer the course of work of structure shown in Figure 3 are described in detail at this.
According to the foregoing description, just can realize the utility model well.
