Description
Technical field
The present invention is a kind of to be referred to a kind of apply for waterborne with underwater remote-control from the floating research and development of anchor that sink to the bottom of floating function
Work ship throws the component of positioning, is particularly suitable for using on busy navigation channel.
Background technology
On ship, it is a kind of important equipment that anchor is floating, for after ship is fixed on precalculated position, it is fixed to anchor into row to ship
Ship is fixed on certain point position, needs to cast around ship by position when carrying out the operations such as waterway dredging, drilling on waterways
Multiple ship anchors, it is floating to need to be correspondingly arranged on multiple anchors, but in existing many navigation channels or harbour, since the density of ship is high,
It is provided directly with the floating airline safety and efficiency for influencing remaining ship of multiple anchors swum on the water surface；If it is floating not set anchor, in ship
When oceangoing ship is unmoored, anchor work can be given to bring difficulty.It floats it is therefore necessary to designing a kind of new anchor and actual uses need to meet
It asks.
This project mainly researches and develops one kind, and to sink to the bottom anchor floating, is only emerged in anchor for unmooring, other times and anchor are floating
Cable sinks to riverbed bottom together, avoids hindering boat.
Invention content
The purpose of the present invention is place against the above deficiency, devises and a kind of sinking to the bottom anchor from floating function with underwater remote-control
It is floating, it can realize the floating remote control of anchor, avoid the floating influence to navigation of anchor, such component principle is simple, easy to operation, recyclable to be made
With with good use and promotion effect.
It is a kind of to sink to the bottom that anchor is floating to take following technical scheme to realize from floating function with underwater remote-control：
It is a kind of with underwater remote-control from floating function it is floating to sink to the bottom anchor includes that air bag, upper shell, lower housing, junction button, remote control buckle
Switch and signal receiver；The upper shell and lower housing size correspond to, and upper shell and lower housing pass through hinge carry out activity
Connection, is provided with through-hole on upper shell or lower housing, is fixedly installed junction button in the outer wall of lower housing, junction button can lead to
Chain connection ship anchor is crossed, when upper shell and lower housing are closed, air bag is placed in the space between upper shell and lower housing,
The valve for inflation/deflation is provided on air bag, valve stretches out through-hole, for facilitating air bag when upper shell and lower housing are closed
It is inflated or deflates.
The other end of hinge is provided with remote control buckle switch on upper shell and lower housing, is remotely controlled on buckle switch
It is provided with signal receiver, for receiving signal, closing between upper shell and lower housing can be controlled by being remotely controlled buckle switch
Conjunction state.
The air bag is not pasted onto the inner wall of upper shell and lower housing.
Compressed air is filled in the air bag, when being remotely controlled buckle switch opening, upper shell and lower housing are in exhibition
Open state, air bag can expand under the pressure of compressed air, and volume becomes larger.
The remote control buckle switch be ultra-short baseline be remotely controlled buckle switch, with remote control buckle switch also it is mating be provided with it is distant
Device is controlled, for controlling remote control buckle switch.
The upper shell and lower housing is spherical, cylindric or capsule shape when being closed, in use, place under water,
Compared to rectangle, triangle, polygon, there is good bearing capacity, and when filling air bag, air bag can be sufficient filling with upper
Shell and lower housing inner wall, effectively eliminate dead angle.
The air bag uses TPU composite materials, has good Waterproof Breathable, radioresistance, wash resistant, abrasion resistance
Energy.
Through-hole edge on the upper shell or lower housing is additionally provided with cushion, for preventing air bag logical in inflation
Be pressurized excessive explosion at bore edges；The cushion is rubber pad.
The edge of the upper shell and lower housing is also each provided with gasket, for when being closed, tightly withholding one
It rises.
The air bag is inflated using air compressor machine.
The upper shell and lower housing uses steel, and it is 220Mpa that the yield strength of steel, which is not less than,；The steel
For HY80 or NS63 steel.
It is additionally provided with lifting lug on the upper shell outer wall, for when in use, this equipment can be lifted by crane by crane.
The lower housing outer wall is additionally provided with hook, and the clump weight that quantity is not limited to one can be carried additionally on hook,
For accelerating to sink when in use.
Operation principle
When in use, air bag is put between upper shell and lower housing, valve is stretched out into the through-hole on upper shell or lower housing, it will
Upper shell and lower housing are closed by being remotely controlled buckle switch, using air compressor machine by valve the injecting compressed air into air bag, wait for
Compressed air stops inflation after reaching predetermined pressure；By the sinking to the bottom with underwater remote-control certainly floating function after inflation, anchor is floating to be put
It sets in the water surface hereinafter, when ship needs to weigh anchor, sends out open signal to remote control buckle switch using remote controler, remote control buckle is opened
It closes and unclamps, air bag struts upper shell and lower housing, and significantly swelling volume, wait for its draining under the action of compressed air
When amount is more than own wt, under the action of buoyancy, the anchor that sinks to the bottom with underwater remote-control from floating function floats upward emersion, and drives
Ship anchor moves upwards, and then extracts ship anchor.
The invention has the advantages that：
1, upper shell and lower housing are steel, and intensity is high, and rigidity is big, and plasticity is strong, upper shell and lower housing can be made to dock close
It is water-tight, and increase installation weight, it can sink to the bottom automatically；
2, air bag uses the TPU composite materials of high-strength pulling-resisting, TPU composite materials to have Waterproof Breathable, radioresistance, wash resistant, resist
The function of abrasion；
3, inflation uses air compressor machine, and the blowing pressure, the floating buoyancy size of control anchor can voluntarily be arranged according to air bag size；
4, remote control buckle switch is remotely controlled using ultra-short baseline, and underwater attenuation is minimum, propagation is stable, highly reliable.
Present inventive concept is ingenious, simple in structure, easy to use, at harbour or navigation channel, compared to
Existing drogue is directly swum on the water surface, and the present invention is located at the bottom when being failure to actuate, and will not touch passing ship, is influenced
The safety and efficiency in course line, and when needing to weigh anchor, it need to only be manipulated by remote controler, so that it may float, can easily pull out
Go out ship anchor, there is good value for applications.
