The invention has the beneficial effects as follows: pass through such scheme, adopt the up and down mode of cover plate to replace the up and down of piston in background technology, first, by expanding support pillar by cover plate jack-up, from intake tunnel, entered not and crossed fixed bearing platform Deng being observed water sample, expanding support pillar drives cover plate to drop to fixed bearing platform, and unnecessary water will flow out naturally, the pressure that while having reduced to a great extent due to buoyancy of water and expanding support pillar that cover plate declines, fixed bearing platform causes cover plate, therefore, cover plate does not need to bear large pressure too, cracky not, simplify the structure greatly, lower to accuracy requirement, cost is lower, be conducive to the installation of light, can for being observed water sample, throw light on preferably.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sampling device detecting for algae of the present invention.
Embodiment
Below in conjunction with accompanying drawing explanation and embodiment, the present invention is further described.
Drawing reference numeral in Fig. 1 is: micro objective 1; Support 2; Intake tunnel 3; Cover plate 4; Illuminating lamp 5; Expanding support pillar 6; Fixed bearing platform 7; Horizontal continuing surface 71.
As shown in Figure 1, a kind of sampling device detecting for algae, comprise the intake tunnel 3 and the support 2 that for injecting, are observed water sample, described support 2 can be the structures on described intake tunnel 3 sides, the top of described intake tunnel 3 is provided with cover plate 4, the bottom of described intake tunnel 3 is provided with the expanding support pillar 6 that can carry out upper and lower stretching motion, one end of the top of described expanding support pillar 6 and described cover plate 4 connects or is hinged, the other end of described cover plate 4 and described support 2 are hinged, the bottom of described intake tunnel 3 is provided with the fixed bearing platform 7 of accepting described cover plate 4, wherein, can control described cover plate 4 by described expanding support pillar 6 rotates around the pin joint of itself and described support 3, and then described cover plate 4 can be covered to described fixed bearing platform 7 detect, can be suspended from again in described fixed bearing platform 7 and pass through for being observed water sample.
As shown in Figure 1, the top of described fixed bearing platform 7 is provided with and accepts and the horizontal continuing surface 71 of the described cover plate 4 of fitting.
As shown in Figure 1, described cover plate 4 is positioned at same level with pin joint and the described horizontal continuing surface 71 of described support 2, because described cover plate 4 has certain thickness, therefore described cover plate 4 also can, a little more than described horizontal continuing surface 71, can be controlled by controlling described cover plate 4 and the pin joint of described support 2 and the distance of described horizontal continuing surface 71 the laminating degree of the horizontal continuing surface 71 of described cover plate 4 and described fixed bearing platform 7 with the pin joint of described support 2.
