Embodiment
Below in conjunction with accompanying drawing, by the description to embodiment, the utility model is described further:
In the utility model gas pumping pipeline, tracer gas waterpower harvester is made up of hydro powered part (1-10), gas collection part (12-28) as depicted in figs. 1 and 2, and two parts are connected by transmission shaft (11).
As shown in Figure 1, first inlet water flow is regulated by the flowrate control valve (1) on water inlet pipe mouth (2), water under high pressure is introduced elementary tank (3), the water entering elementary tank (3) forms four bursts of pressure water jets impact blades (6) by four water diversing heads (4), blade (6) impeller (7) is rotated, thus the kinetic energy of water being converted to the mechanical energy of impeller (7), the water after blade (6) is discharged through external pipe by freeing port (10).
As shown in Figure 2, drive bevel pinion (15) to rotate by transmission shaft (11), bevel pinion (15) drives bevel gear wheel (16) to rotate by engagement, thus realizes transmission reduction of speed.Driving disk (19) rotates under the drive of transmission shaft (17), pin (20) is fixed on driving disk (19), drive link (21) is moved back and forth along with the rotation of driving disk (19) by pin (20), thus drive piston (22) moving back and forth in piston/cylinder (23), in the process that piston (22) moves backward, the retaining valve (25) that the retaining valve (24) connecting gas pumping pipeline is opened and connects gas collection bag is closed thus realizes breathing process, in the process of piston advances forward, retaining valve (24) is closed and the retaining valve (25) connecting gas collection bag is opened thus realizes exhaust process.Need bleed screw (26) to open before each collection gas sample, after retaining valve (24) is connected with extraction negative-pressure pipeline, runs certain hour tightens bleed screw (26) again to get rid of other gases in piston/cylinder (23), to ensure the purity of collector sample.
In gas pumping pipeline, tracer gas waterpower harvester not only can be applied to the sample acquisitions of tracer gas in the gas pumping negative-pressure pipeline of mine, also all can have a wide range of applications for gas sample sample acquisitions in various transport, extraction pipeline.Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
