Specific implementation mode
It is described in detail such as in order to further understand the content, features and effects of the present invention, the following examples are hereby given Under:
Fig. 1 is referred to, the present invention includes fluid reservoir 1, driving mechanism 4 and the anti-corrosion machine in water body equipped with medicament Structure 8.Wherein, protection medicament is loaded in fluid reservoir 1, protection medicament is supplied to anti-corrosion mechanism 8, and driving mechanism 4 is for driving 8 action response of anti-corrosion mechanism.
Fig. 2 is referred to, driving mechanism 4 includes shell 4-3, and circuit board 4-1 and motor 4-2 is equipped in the inner cavity of shell 4-3, The motor shaft of motor 4-2 is pierced by by the bottom wall of shell 4-3.Specifically:Shell 4-3 includes the shell and bottom that sealing docking fastens 4-4 is covered, motor 4-2 is fixedly mounted on bottom cover 4-4, and sealing ring is arranged between bottom cover 4-4 and shell.The advantages of above structure It is:Driving mechanism 4 is enabled integrally to be convenient for assembly and disassembly.
Motor 4-2 can be powered by external power supply and power cord, also battery can be arranged in shell 4-3.
Fig. 3 is referred to Fig. 5, it can be seen that:Anti-corrosion mechanism 8 carries water quality instrument mounting hole including be located above, middle part Upper end cover 8-12 and underlying bottom plate 8-8, the metal mesh 8-14 of tubular is equipped with therebetween, on metal mesh 8-14 Mesh enable extraneous water body be connected to and ensure mobility with inner cavity, data progress of the water quality instrument to water body mounted on center Acquisition.In order to promote corrosion resistance, metal mesh 8-14 can be chosen for red copper material.
The top frame 8-1 for playing the role of strengthening and fixing can be set in the top of upper cover 8-12, promote overall structure Installation while intensity convenient for from water quality instrument to 8 center of anti-corrosion mechanism.
It is also set up between upper end cover 8-12 and bottom plate 8-8 and the leading screw 8-11 with screw 8-10, leading screw 8-11 is installed Upper end by being pierced by the through hole that is opened on upper end cover 8-12, as shown in Figure 3, on upper end cover 8-12 and bottom plate 8- Bearing is mounted on 8, leading screw 8-11, which is set up, to be mounted between bearing.The motor shaft of motor 4-2 passes through shaft and leading screw 8-11 Upper end connection transmission.Under the driving of motor 4-2, leading screw 8-11 is rotated forward or reversion.Further include lifting ring flat-plate 8-6, in Edge is fixedly connected with screw 8-10.When leading screw 8-11, which is rotated forward, either to be inverted screw 8-10 drive lifting ring flat-plate 8-6 rise or Decline.
In the present embodiment, in order to ensure to lift the stationarity of ring flat-plate 8-6 liftings, between upper end cover 8-12 and bottom plate 8-8 It also sets up and guide post 8-3 is installed, guide sleeve 8-5 is equipped on guide post 8-3, guide sleeve 8-5 is fixedly connected with lifting ring flat-plate 8-6.Guide post 8-3 enables lifting ring flat-plate 8-6 strictly in axial direction move with guide sleeve 8-5 cooperations, ensures mobile stationarity.
In view of the environment of water fluctuation can have an impact the transmission between driving mechanism 4 and anti-corrosion mechanism 8, this reality It applies in example, upper cruciform joint 5 is installed on the motor shaft of motor 4-2, lower cruciform joint is installed in the upper end of leading screw 8-11 7, two cruciform joints are using the connection transmission of Telescopic rotating axis 6.In this way, in the water body environment of fluctuation, shaft can either be lateral Offset twisting again can upper and lower telescopic adjustment, be always ensured that suitable transmission effect.
Bellows 8-13 is equipped between lifting ring flat-plate 8-6 and upper end cover 8-12, the upper end is fixed with upper end cover 8-12 to be connected It connects, lower end is fixedly connected with lifting ring flat-plate 8-6.During lifting ring flat-plate 8-6 lifting movings, bellows 8-13 shrink or Stretch, after contraction the inner cavity of metal mesh 8-14 with by mesh with the external world water body be connected to, after stretching the inner cavity of metal mesh 8-14 and Extraneous water body partition, in this way when water quality instrument is in off working state, slows down the attachment of impurity by being separated with extraneous water body The pollution corrosiveness of effect and water body.
Protection medicament in fluid reservoir 1 is supplied to the inner cavity of metal mesh 8-14, and outlet is connected to metal by woven hose The inner cavity for netting 8-14 is equipped with tablet cabin 8-7 on bottom plate 8-8, and the tablet for playing sustained release protective action is placed on tablet cabin 8-7 Interior and periodically replaced, above two medicament acts synergistically on the water body around water quality instrument, reaches that slow down attachment rotten with pollution The effect of erosion.
Further include in fluid reservoir 1 to promote the patency that the medicament in fluid reservoir 1 is supplied into anti-corrosion mechanism 8 Medicament carries out the device of compressing discharge.Specifically:The device includes that one end is connected to air source, the other end is connected in fluid reservoir 1 The air inlet pipe 3 of chamber is equipped with solenoid valve 2 in air inlet pipe 3, and the break-make by controlling solenoid valve 2 is realized to being pumped into gas in fluid reservoir 1 The control of the scale of construction.Internal pressure increases after being pumped into gas, and medicament is extruded out and be conveyed along woven hose.
Further, it is equipped with perforation on upper end cover 8-12 and meets mouth 8-15 to the inner cavities metal mesh 8-14, under woven hose Hold and connect mouth 8-15 plug connections.
In view of the sterilization demand that the microorganism sclerozone in water body comes, can be arranged on this anti-adhesion environmental control system Sterilizing unit.Specifically, the fluorescent tube 8-2 for installing multiple sealing two ends is set up between upper end cover 8-12 and bottom plate 8-8, in fluorescent tube Setting ultraviolet lamp 8-4 is irradiated sterilization by the bright ultraviolet lamp 8-4 of timing point to the water body around water quality instrument in 8-2.However, Impurity in water body would also adhere on the outer wall of fluorescent tube 8-2 and reduce the transmitance of ultraviolet light, and then influence bactericidal effect, therefore Can be that fluorescent tube 8-2 configures cleaning mechanism.
Specifically, it is fixedly mounted on lifting ring flat-plate 8-6 and clean sweeper 8-9, sweeper 8- is carried out to each fluorescent tube 8-2 9 include the annular preform being set on each fluorescent tube 8-2, and inner edge has been gripped in annular preform and has been contacted with the surfaces fluorescent tube 8-2 Annular scraping blade.In this way, when lifting ring flat-plate 8-6 lifting movings, above-mentioned annular scraping blade to the surface of fluorescent tube 8-2 scrape clear It is clean, remove attachment.
Can also include buoy, fluid reservoir 1 and driving mechanism 4 are mounted on buoy, that is, are located at the water surface or more, anti-corrosion mechanism 8 by shaft with infusion pipe pendant in water body.
