The present invention also provides a kind of algae detection system, comprises the described sampling device that algae detects that is used for.
The invention has the beneficial effects as follows:, adopt the up and down mode of cover plate to replace the up and down of piston in the background technology, at first through such scheme;, wait by the observation water sample and got into not fixed bearing platform from intake tunnel cover plate jack-up through flexible fore-set, flexible fore-set drives cover plate and drops to fixed bearing platform; And unnecessary water is with flowing out, because buoyancy of water and flexible fore-set have reduced the pressure that fixed bearing platform caused cover plate when cover plate descended to a great extent, therefore naturally; Cover plate need not bear big pressure too, and cracky does not simplify the structure greatly; Lower to accuracy requirement; Cost is lower, helps the installation of light, can be preferably for being thrown light on by the observation water sample.
Description of drawings
Fig. 1 is a kind of structural representation that is used for the sampling device of algae detection of the present invention.
Embodiment
Below in conjunction with description of drawings and embodiment the present invention is further specified.
Drawing reference numeral among Fig. 1 is: micro objective 1; Support 2; Intake tunnel 3; Cover plate 4; Illuminating lamp 5; Flexible fore-set 6; Fixed bearing platform 7; Horizontal continuing surface 71.
As shown in Figure 1, a kind of sampling device that is used for the algae detection comprises being used to inject the intake tunnel 3 and support 2 by the observation water sample; Said support 2 can be the structures on said intake tunnel 3 next doors; The top of said intake tunnel 3 is provided with cover plate 4, and the bottom of said intake tunnel 3 is provided with can carry out the flexible fore-set 6 of stretching motion up and down, and an end of the top of said flexible fore-set 6 and said cover plate 4 connects or is hinged; The other end of said cover plate 4 and said support 2 are hinged; The bottom of said intake tunnel 3 is provided with the fixed bearing platform 7 of accepting said cover plate 4, wherein, can control the pin joint rotation of said cover plate 4 around itself and said support 3 through said flexible fore-set 6; And then said cover plate 4 can be covered to said fixed bearing platform 7 detect, can be suspended from again and supply on the said fixed bearing platform 7 to be passed through by the observation water sample.
As shown in Figure 1, the top of said fixed bearing platform 7 is provided with accepts and the horizontal continuing surface 71 of the said cover plate 4 of fitting.
As shown in Figure 1; Said cover plate 4 is positioned at same surface level with the pin joint and the said horizontal continuing surface 71 of said support 2; Because said cover plate 4 has certain thickness; The pin joint of therefore said cover plate 4 and said support 2 also can be a little more than said horizontal continuing surface 71, and pin joint that can be through controlling said cover plate 4 and said support 2 and the distance of said horizontal continuing surface 71 are controlled the applying degree of the horizontal continuing surface 71 of said cover plate 4 and said fixed bearing platform 7.
As shown in Figure 1; Be provided with illuminating lamp 5 in the said fixed bearing platform 7; Said horizontal continuing surface 71 is processed for light transmissive material, and said illuminating lamp 5 can shine the water sample of being observed that is positioned on the said horizontal continuing surface 71 through said horizontal continuing surface 71, and water sample is observed in convenient better observation.
As shown in Figure 1, said horizontal continuing surface 71 is a transparent glass.
As shown in Figure 1, the said intake tunnel 3 outer micro objectives 1 that are provided with.
As shown in Figure 1, said micro objective 1 is suspended from the said fixed bearing platform 7, and said micro objective 1 is suspended from the said cover plate 4; Said cover plate is an euphotic cover plate, when said cover plate 4 fits to said fixed bearing platform 7, controls said micro objective 1 again and descends; Focusing gets into photographing phase, is observed water sample with better observation.
As shown in Figure 1, said cover plate 4 is a tabular.
As shown in Figure 1, when an end of the top of said flexible fore-set 6 and said cover plate 4 connected, said cover plate 4 was the deadweight cover plate, can descend through its deadweight.
As shown in Figure 1; A kind of algae detection system comprises filming apparatus, image analysis processing unit and the described sampling device that is used for the algae detection, wherein; Said micro objective 1 is connected with said filming apparatus; Said filming apparatus is connected with said image analysis processing unit, is used for environmental protection, tap water and water conservancy industry the harm of water body algae is detected assessment, uses automatic classification and concentration computing technique based on graphical analysis to replace conventional artificial naked eyes recognition techniques; Significantly reduce the workload that algae detects, shorten detection time.
A kind of sampling device and algae detection system that algae detects that be used for provided by the invention adopts cover plate 4 up and down modes to replace the up and down of piston in the background technology, at first, through flexible fore-set 6 with cover plate 4 jack-up; Wherein, flexible 6 pairs of waterproof requirements of fore-set are not high, can reduce waterproof requirement; Secondly, flexible fore-set 6 can supply again to be observed water sample pass through, and is unlikely to stop by the observation water sample; Got into not fixed bearing platform 7 Deng by the observation water sample from intake tunnel 3, flexible fore-set 6 drives cover plate 4 and drops to fixed bearing platform 7, and unnecessary water is with flowing out naturally; Because the pressure that 71 pairs of cover plates 4 of horizontal continuing surface that buoyancy of water and flexible fore-set 6 have reduced cover plate 4 decline fixed bearing platform 7 to a great extent cause, therefore, cover plate 4 need not bear big pressure too; Cracky does not simplify the structure greatly, and is lower to accuracy requirement; Cost is lower, helps the installation of light, can be preferably for being thrown light on by the observation water sample.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
