Description
Technical field
The utility model is related to a kind of easy-to-read water body optical attenuation system when being conducted a field operation suitable for monitoring ship
Number measurement apparatus.
Background technology
At present LI-1400 data acquisition units are typically used in China's environmental monitoring（Main frame）With LI-COR light quantities under water
Sub- sensor determines water body light attenuation coefficient.It is directly connected between the two by signal wire.Existing light attenuation coefficient monitoring is read
Counting method is usually the scale mark that a determining deviation is drawn on signal wire, sensor is immersed in water body, by under certain length
Put, tracer signal line transfers the corresponding main frame numerical value of certain scale.But the precision so measured is not high enough.
China Patent Publication No. discloses a kind of enclosed light attenuation coefficient under water for 102608037A patent of invention
Measurement apparatus, the device is to close inlet water tank survey tool.This its defect is：Equipment instrument is big, and empty van is floating by water body during decentralization
Power acts on inconvenient operation；Secondly, water body enters water tank on top layer, and water body, which is exchanged, during decentralization may not clearly result in measurement mistake
Difference, and monitoring repeatedly can cause field monitoring time-consuming longer.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of water body light attenuation coefficient measurement apparatus, can solve
The problem of stress that typical measuring arrangements drift band in water is larger and signal wire easily rubs is damaged, measurement accuracy is higher.
In order to solve the above-mentioned technical problem, the utility model proposes following technical scheme：A kind of water body light attenuation coefficient is surveyed
Device is measured, it includes many supervisors, and many supervisors thickness is different, and is sequentially connected by socket mode, the supervisor's
Outer wall, which is provided with the top of scale, the supervisor, is provided with level meter, and the inside of the supervisor is provided with signal wire, the signal
Line one end passes through the mouth of pipe that bottom is responsible for, and bypasses frame bottom annulus and is connected on Fixing clamp-seat, is installed on the Fixing clamp-seat
There is sensor, the signal wire other end is connected to main frame through supervisor top, and there is gravity drop hammer in the annulus bottom system.
Socket can be stretched between the supervisor, and adhesive tape bind is used between the supervisor and support.
The supervisor is stainless steel or aluminium bar.
The gravity drop hammer is taper drift.
The utility model has the advantages that：
The water body light attenuation coefficient measurement apparatus that the utility model is provided, after sensor is transferred into water, hand-held supervisor
It is easily operated that sensor can be made quickly to transfer to target location, due to be supervisor, and be provided with par instrument above, maintain steady
Timing can significantly reduce the influence of water velocity and stormy waves, therefore will not produce and significantly drift about, and require small to environmental condition.Separately
Outside, the influence of scale-wearing can be avoided using supervisor's scale reading, and signal wire wear damage can be avoided.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the utility model structural representation.
In figure, supervisor 1, scale 2, level meter 3, signal wire 4, support 5, annulus 6, Fixing clamp-seat 7, sensor 8, main frame 9,
Gravity drop hammer 10.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Such as Fig. 1, a kind of water body light attenuation coefficient measurement apparatus, it includes many supervisors 1, and 1 thickness of many supervisors is not
Together, and by socket mode it is sequentially connected, the outer wall of the supervisor 1 is provided with scale 2, and the top of the supervisor 1 is provided with water
Level 3, the inside of the supervisor 1 is provided with signal wire 4, and described one end of signal wire 4 is responsible for 1 mouth of pipe through bottom, bypasses branch
The bottom annulus 6 of frame 5 is connected on Fixing clamp-seat 7, and sensor 8, the other end of signal wire 4 are provided with the Fixing clamp-seat 7
Through the top of supervisor 1, and main frame 9 is connected to, there is gravity drop hammer 10 in the bottom system of annulus 6.
Further, it is socketed and can be stretched between the supervisor 1, is tied up between the supervisor 1 and support 5 with adhesive tape
Connect.
Further, the supervisor 1 is stainless steel or aluminium bar.It is capable of the use longevity of extension fixture using metal material
Life.
Further, the gravity drop hammer 10 is taper drift.
The course of work of the present utility model is as follows：
First, after monitoring ship comes to a complete stop and casts anchor, socket is got up between being responsible for 1 by many, and sensor 8 is connected with support 5
Connect, gravity drop hammer 10 is fastened in the bottom of support 5, by the bind of support 5 on supervisor 1, the one end of signal wire 4 connects through supervisor 1 with main frame 9
Connect, the other end bypasses annulus 6 and is connected on Fixing clamp-seat 7；
Now supervisor 1 is stretched out and transfers to certain position, the stabilization of par instrument 3 is maintained, reads the reading of main frame 9 under the depth
Number, so operation are transferred to the respective depth record reading of main frame 9, the corresponding light radiation intensity under water of this reading correspondence successively, then
Light attenuation coefficient curve corresponding with the depth of water is gone out by digital simulation, so as to draw light attenuation coefficient.
By using the utility model device using simple, conveniently, can solve sensor in current drift band compared with
The problem of big, it is easy to wear also to solve scale, the flimsy problem of signal wire, moreover it is possible to ensure higher measurement accuracy.
By above-mentioned description, those skilled in the art completely can be without departing from this utility model technological thought
In the range of, various changes and amendments are carried out all within protection domain of the present utility model.It is of the present utility model not most
Matters, belong to the common knowledge of those skilled in the art.
