nullAs shown in Figure 1 to Figure 3: the present embodiment additionally provides a kind of scenic spot water area water-quality monitoring system，Including Surveillance center 1 and distant-end node 2，Described distant-end node 2 includes the bearing floating body 3 arranged on the water surface，Described bearing floating body 3 is internal arranges cavity 4，Described cavity 4 both sides are correspondingly arranged pedestal 5，Between described pedestal 5, piezoelectric cantilever 6 is set，Described piezoelectric cantilever 6 is fixedly installed the insulation collar 7，The described insulation collar 7 is arranged below pull bar 8，Corresponding described pull bar 8 is arranged below through hole 9 in described bearing floating body 3，Between described pull bar 8 and described through hole 9, sealing mechanism 10 is set，Described pull bar 8 lower end is connected by rope body 11 and the bottom are fixing，Described piezoelectric cantilever 6 is connected with Power Management Unit 12，Described Power Management Unit 12 and monitoring means 13、Processor unit 14 and communication unit 15 connect.
Described sealing mechanism 10 includes annular sealing strip 27, and the inward flange of described annular sealing strip 27 and described pull bar 8 are tightly connected, and the outward flange of described annular sealing strip 27 and described bearing floating body 3 lower surface are tightly connected.This sealing mechanism is similar to automobile shelves the sealing structure of lower section, and annular sealing strip adopts flexible corrosion protection encapsulant to make, and pull bar still can move up and down in through hole.The present invention is provided without hard sealing, because the pulling force that pull bar is downward is oblique by rope body, is firmly sealed in service life in this case shorter, and frictional force is relatively big, and effect is general.
Described pull bar 8 lower end is connected with described rope body 11 by swivel joint, and described swivel joint includes described pull bar 8 lower end and arranges the fixing groove 28 of annular, arranges swivel becket 29 in the fixing groove 28 of described annular, and described swivel becket 29 is connected with described rope body 11.The range of operation of bearing floating body is defined by rope body, and bearing floating body is likely to result in the rotation of rope body when mobile, and this rotation can be discharged by swivel joint, it is to avoid the devices such as the insulation collar are caused damage by rotation dynamics, it is ensured that the safety that equipment uses.
What finally illustrate is, above example is only in order to illustrate technical scheme and unrestricted, other amendments that technical scheme is made by those of ordinary skill in the art or equivalent replace, without departing from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of scope of the presently claimed invention.
