Description
Technical field
A kind of heavy pendant is the utility model is related to, more particularly to a kind of heavy pendant of bottomed prompting.
Background technology
Halomereid investigation divides Survey of level and vertical investigation.Wherein vertical research operations are that first planktonic organism is adjusted
Look into netting gear to be put into water, then wait netting gear to sink to seabed completely, then netting gear is brought up from seabed to the water surface, finally collected
Planktonic organism sample after netting gear filtering.The key points for operation of the vertical investigation of halomereid, therefore, to assure that netting gear sinks to sea
Bottom, is then again brought up netting gear, is so only a qualified planktonic organism and vertically investigates.If netting gear does not sink to bottom,
Investigation so to the vertical biomass of this sampled point be exactly it is incomplete, cannot accurate response this points for investigation it is vertical
Biotic component.Such as investigation fish-egg larvae juvenile fish, fish-egg can divide buoyant egg and demersal egg, if points for investigation have accumulated demersal egg, and
Netting gear does not sink to seabed during investigation, and that will bring great deviation to investigation result.Therefore, halomereid is vertical
It is the key for investigating success or failure that investigation, which ensures that netting gear successfully sinks to seabed,.
The situation of actual marine investigation is considerably complicated, and the ocean current in ocean is more, if running into the anxious ocean current of comparison, netting gear is very
May be rushed by ocean current it is far also do not sink to seabed, the crewman on such case lower decks, which may be because, has put long enough
Rope, think to shift to an earlier date on earth and be brought up net, actually netting gear is not also arriving seabed.Severe day is met again
Gas, stormy waves is very big, and crewman may wait without the longer time and guess whether netting gear sinks to seabed, and such netting gear can not sink
The situation that bottom is just brought up will increase a lot, so as to cause the result of investigation inaccurate and unreliable.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of heavy pendant of bottomed prompting, can be reminded the bottom of after
Staff, for aiding in plankton net vertically to investigate, it is ensured that netting gear can sink to seabed.
Technical scheme is to provide a kind of heavy pendant of bottomed prompting used by the utility model solves its technical problem, including
Falling body and rope, the falling body are in integrally cone structure wide at the top and narrow at the bottom, and the falling body is along central shaft provided with passing up and down
Empty steel column, the trigger of the bottom insertion waterproof anticollision of the hollow steel column, top are provided with interface, are coated with inside the rope
Two electric wires for being used to form loop, the rope are connected with hollow steel column, the electric wire upper end and battery box and indicator lamp
Series winding, lower end are connected to interface and formed using trigger as the circuit switched.
As a kind of preferred embodiment of the utility model, the hollow steel column side is interval with circular hole, the pendant
By quantity is adjustable, the round sheet pendant block of diameter not etc. forms, the round sheet pendant block inserts circular hole by latch and fixed body
In the side of hollow steel column.
As a kind of preferred embodiment of the utility model, middle cavity that the wiring of the trigger passes through hollow steel column
It is connected to interface.
As a kind of preferred embodiment of the utility model, the interface peripherals have water-proof protection cover.
As a kind of preferred embodiment of the utility model, the top of the hollow steel column is cast with the extension of integrative-structure
Ring, the lower end of the rope are connected with link.
As a kind of preferred embodiment of the utility model, the top of the hollow steel column is provided with jack, the rope
Lower end be connected through jack with hollow steel column.
As a kind of preferred embodiment of the utility model, two electric wires of cladding are through at pressure-resistant anti-inside the rope
In the plastic tube of drawing, the rope is knitted to form centered on plastic tube.
Beneficial effect
In the utility model, when it is heavy fall bottom after, trigger is touched so that whole circuit communication, the finger of rope end
Show that lamp can provide bottom instruction, to inform staff.The utility model can be used for aiding in plankton net vertically to investigate,
Ensure that netting gear can sink to seabed, so as to ensure the integrality of fact-finding process, the accuracy that lifting plankton net is vertically investigated.
