Specific embodiment one: as shown in Figure 1, one kind, which bottoms out formula anti-interference type, adopts wetting system, including traction rope 8, branch support group
Seat 1, the vertical guide sleeve 3 being arranged in support base, is slidably arranged in vertical guide sleeve the bracket 2 being arranged in support base
Sliding mandril 4 and the hydrophore 5 that is arranged on bracket.It is connected at the top of one end of traction rope and bracket, specifically, bracket
Including the upper frame bar on being horizontally disposed with, upper frame bar is located at the top of hydrophore, and one end of traction rope is connected with the upper frame bar of bracket.
Support base is concrete pedestal.The lower part of support base is cylindrical body, and the top of support group seat is round estrade.Vertically
Guide sleeve is coaxial with support base.The vertical upper port of guide sleeve is connected with the top surface of support base, the lower port of vertical guide sleeve with
The bottom surface of support base is connected.
The upper end of sliding mandril passes through the upper port of vertical guide sleeve and is located at the top of vertical guide sleeve.The lower end of sliding mandril
Lower port across vertical guide sleeve and the lower section positioned at vertical guide sleeve, the lower end of sliding mandril, which is equipped with, shores plate 6.Support base
The area of bottom surface be greater than and shore the surface area of plate.
The bottom surface of support base is equipped with magnet 7, and magnet is embedded in support base, the lower end surface of magnet and support base
Bottom surface flush.Magnet is located at the surface for shoring plate.Shoring plate is iron plate, when the bottom shored plate and be against support base
When on face, shores plate and be adsorbed on magnet.
In the present embodiment, hydrophore 5 is two, and two hydrophores are distributed along the axisymmetrical of vertical guide sleeve.
As shown in Figure 1 and Figure 2, before hydrophore includes the horizontal cylinder body 5.1 being arranged on bracket, cooperates with horizontal cylinder body
Piston body 5.3 with rear piston body 5.4, the piston rod 5.5 for connecting secondary piston body and rear piston body, the level being arranged on bracket
Guide sleeve 5.6 and the guide rod 5.2 being slidably arranged in horizontal guide sleeve.The both ends open of horizontal cylinder body.
In same hydrophore: horizontal guide sleeve and horizontal cylinder body are coaxial, and horizontal cylinder body, secondary piston body and rear piston body are located at water
The same side of flat guide sleeve, secondary piston body and horizontal guide sleeve are located at the opposite sides of rear piston body.
One end of guide rod is connected with the end face of corresponding rear piston body.The other end of guide rod is pushed up by connecting rod 9 and sliding
The upper end of bar connects, and one end of connecting rod 9 and the end of guide rod are hinged and connected, and the other end of connecting rod 9 and the upper end of sliding mandril are cut with scissors
It connects connected.
As shown in Fig. 2, secondary piston body and rear piston body are located at level when rear piston body is against on the end face of horizontal guide sleeve
Between cylinder body and horizontal guide sleeve.
When shoring plate and being against on the bottom surface of support base, the secondary piston body and rear piston body are located at horizontal cylinder body
It is interior.
It is specifically used as follows,
Firstly, as described in Figure 1, the rear piston body of hydrophore is against on the end face of horizontal guide sleeve, plate and support are shored at this time
The bottom surface of pedestal separates, and shores the lower section that plate is located at the bottom surface of support base；
Then, formula anti-interference type will be bottomed out from ship by traction rope and adopts wetting system into the water, until support base is supported on
It before base supports are contacted with seabed, shores plate in this process and contacts elder generation with seabed in seabed；When shoring plate
After contacting with seabed, sliding mandril moves down stopping, and base supports, bracket and hydrophore will continue to move down, sliding during this
Dynamic mandril will drive guide rod and secondary piston body to move in corresponding horizontal cylinder body with rear piston body by connecting rod, make secondary piston body
It is moved in corresponding horizontal cylinder body with rear piston body, hereafter, base supports continue to move down, until support base is supported on sea
Bottom is shored plate at this time and is against on the bottom surface of support base, shores plate and be adsorbed on magnet.
Since before support base is supported on seabed, secondary piston body is moved to corresponding horizontal cylinder body with rear piston body
It is interior, in this way, support base hits the level that the slime water that seabed is evoked will not enter between secondary piston body and rear piston body
In cylinder body, entered between secondary piston body and rear piston body in horizontal cylinder body so that support base be avoided to bottom out the slime water evoked
(the intracorporal water of horizontal cylinder between secondary piston body and rear piston body is the seabed water sample acquired), when effectively solution weight bottoms out
The problem of slime water can be evoked, and influence the quality of the acquired water sample of hydrophore；
Followed by will bottom out formula anti-interference type by traction rope and adopt wetting system and lift, and realize the sampling of bottom water.Due to pushing up at this time
Support plate is adsorbed on magnet, to guarantee preceding work during traction rope will bottom out formula anti-interference type and adopt wetting system and lift
Cock body is always positioned in corresponding horizontal cylinder body with rear piston body.
The above is only presently preferred embodiments of the present invention, is not intended to limit the invention in any way, it is all according to the present invention
Technical spirit any simple modification, change and equivalent transformation to the above embodiments, still fall within the technology of the present invention side
The protection scope of case.
