In the top of inside connecting rod.
Lateral water inlet line is circumferentially uniformly distributed around vertical pipeline is determined.Determine radially extending for vertical pipeline in lateral water inlet line edge.
The first end of lateral water inlet line is connected with the inner cavity for determining vertical pipeline.The second end of lateral water inlet line is opened
Mouthful, and the first check valve 8.1 is equipped in the second end opening of lateral water inlet line.First check valve allows extraneous seawater logical
The first check valve is crossed to enter in lateral water inlet line.
Inside connecting rod is located at the top of the first end of lateral water inlet line.
As shown in Figure 1 and Figure 2, floating type detection device includes positioned at the support scaffold 7.1 determined below vertical pipeline, is located at
Determine the vertical guide sleeve 7.2 on the outside of vertical pipeline, the vertical guide sleeve of connection and determines the outer tie rod of vertical pipeline, is arranged in support scaffold
Upper and the vertical guide rod 7.3 being slidably matched with vertical guide sleeve, the transparent cabinet 7.4 that is arranged on support scaffold upper surface and setting
In the intracorporal photographic device 7.5 of glass box and/or camera arrangement.Vertical guide sleeve is close to the lower end for determining vertical pipeline.Support scaffold
Buoyancy be greater than floating type detection device gravity.It is additionally provided in transparent cabinet and provides electricity for photographic device and/or camera arrangement
The battery in source.
The camera lens of photographic device or camera arrangement is arranged upward, and the camera lens of photographic device or camera arrangement is positioned at fixed vertical
The underface of the lower ending opening of pipeline.
Transparent cabinet is located at the lower section for determining vertical pipeline.The upper surface of transparent cabinet is plane.
When the upper surface of transparent cabinet is against on the lower end surface for determine vertical pipeline, the upper surface envelope of transparent cabinet hides fixed perpendicular

There is gap between the upper surface of body and the lower end surface for determining vertical pipeline.
The specific works of the sea area reparation area fishery resources monitoring system of the present embodiment are as follows:
Photographic device shoots the inner cavity for the lower part for determining vertical pipeline by determining the lower ending opening of vertical pipeline.
As shown in Figure 1, utilizing the fluctuation of wave by floating frame, constantly float up and down;
During floating frame band floats, floating frame drives dynamic vertical pipeline to move up together by upper connecting rope, in dynamic vertical pipe
During road moves up:
Transparent cabinet is determined under vertical pipeline in the buoyancy float downward of support scaffold up to the upper surface of transparent cabinet is against
Until Gask-O-Seal on piece on end face, the upper surface envelope of transparent cabinet hides the lower ending opening for determining vertical pipeline,
Since during dynamic vertical pipeline moves up, the upper surface envelope of transparent cabinet hides the lower ending opening for determining vertical pipeline, and
The lower end closed of dynamic vertical pipeline, so that entering extraneous seawater by the first check valve and lateral water inlet line determines vertical pipe
The lower part in road;
In floating frame folding process, dynamic vertical pipeline is moved down under the action of corresponding tension spring, is resetted, during this
Since the first check valve prevents the seawater in lateral water inlet line from being discharged by the first check valve, to force under dynamic vertical pipeline
The water of side determined in vertical pipeline pushes transparent cabinet down, passes water through the lower port discharge for determining vertical pipeline;
In this way, the seawater in a part of external world can be made to pass through the first check valve and cross during floating frame floats every time
The lower part for determining vertical pipeline is pumped into water inlet line, so that extraneous seawater is constantly pumped into the lower part for determining vertical pipeline,
Then it is discharged by determining the lower ending opening of vertical pipeline;In this way, photographic device is by determining the lower ending opening of vertical pipeline to erecting surely
The process that the inner cavity of the lower part of straight pipeline is shot can effectively take the fish-egg that drifts about in water, and can effectively mention
Effective monitoring region of the height to drift fish-egg in water.
On the other hand, in floating frame folding process, it will force the water determined in vertical pipeline below dynamic vertical pipeline will
Transparent cabinet pushes down, passes water through the lower port discharge for determining vertical pipeline, water flow will wash away glass box in this process
The upper surface of body avoids deposit etc. from assembling or be attached to the upper surface of transparent cabinet, and the problem of the clarity of influence shooting.
