Abstract
The utility model relates to a submerged buoy breaking protection device comprising two groups of chinlon ropes arranged in a submerged buoy system, which are connected between two shackles. As the breaking force of each chinlon rope is a constant, the number of the chinlon ropes can be adjusted according to the gravity and the buoyancy of the submerged buoy system, so as to enable the breaking force of the submerged buoy breaking protection device to be greater than a normal pulling force for laying and withdrawing a submerged buoy and less than the net weight of the submerged buoy system in water. During normal laying and withdrawing, as the group of short chinlon ropes can be subject to plastic deformation and influence the pulling force of the submerged buoy breaking protection device in normal operation, the two groups of chinlon ropes are adopted and the group of long chinlon ropes are doubled over and then fixed with adhesive tapes. When the submerged buoy part at the upper end of the submerged buoy breaking protection device is dragged for certain reasons, the two groups of chinlon ropes are broken because the breaking forces of the two groups of chinlon ropes are smaller than the net weight of the submerged buoy system in the water, so as to achieve the effect of protecting a buoy body at the lower end of the submerged buoy breaking protection device.
Description
Technical field
The utility model relates in a kind of marine monitoring technology the submerged buoy system problem of safety guard-safeguard under water, is the disrumpent feelings fender guard of a kind of subsurface buoy specifically.
Background technology
Subsurface buoy be a kind of under the sea device of long-term Measuring Oceanic key element.At present, China's subsurface buoy is made up of buoyant material, Kevlar cable, scientific instrument, anchor chain and anchor mostly, is connected by the Kevlar cable between buoyant material and the scientific instrument.When subsurface buoy near the fishing ground or coastal waters when laying because the end distance water surface is closer on the subsurface buoy, may cause fishing net or other object to scrape the buoyant material or the scientific instrument of subsurface buoy upper end.Because the breaking force of Kevlar cable is certain, so just may cause whole submerged buoy system to be pulled, scientific effort can not be carried out smoothly.Therefore, buoyant material and scientific instrument on the subsurface buoy are reduced the loss as far as possible, become subsurface buoy engineering urgent problem.
Summary of the invention
The purpose of this utility model provides the disrumpent feelings fender guard of a kind of subsurface buoy, with the normal operation of protection submerged buoy system.
Basic structure of the present utility model is to be connected two groups of caprone cables that are uneven in length between two shackles in the submerged buoy system.The extreme length of the stretching before the length of wherein long rope is should be greater than short rope disrumpent feelings prevents from normally to lay the excessive caprone cable plastic deformation that causes of instantaneous pulling force when reclaiming and the pulling force that influences disrumpent feelings protection.Choosing long caprone cable in this disrumpent feelings fender guard is short three times, and long caprone cable doubling once, the blended rubber band is fixed.When rupture pull force normally lays the pulling force when reclaiming greater than subsurface buoy and during less than the net weight power of submerged buoy system in water, this fender guard takes place disrumpent feelings.
Obviously, the utility model has reduced the problem of losing of buoyant material and scientific instrument effectively, has improved the efficient that subsurface buoy reclaims.

Wherein, the scientific instrument of buoyant material 11 lower floors of long caprone cable 9 adhesive tapes of the short caprone cable of the fixing knot of scientific instrument 3 Kevlar cables 4 shackles 5 anchors 6 tents on buoyant material 2 upper stratas on 1 upper strata 78 10 lower floors.
The specific embodiment
The utility model is short caprone cable 7 and the long caprone cable 8 that is connected in the submerged buoy system between two shackles 4.
Through experiment test, when making its deformation reach the twice left and right sides of raw footage, the suffered pulling force of caprone cable just plastic deformation can take place and finally disrumpent feelings, and that therefore long group caprone cable generally is taken as short three times.As shown in Figure 1, the utility model is chosen short caprone cable 7 and is 50cm, and long caprone cable 8 is 150cm, and long caprone cable 8 doublings are fixed as 60cm with adhesive tape, and fag end all twines with adhesive tape 9.Normally lay normally in the removal process in subsurface buoy, to cause the plastic deformation of short caprone cable 7 to take place disrumpent feelings because instantaneous pulling force is crossed conference, and that long caprone cable 8 can not take place in its elastic deformation is disrumpent feelings, plays the effect of double shielding.Generally speaking, every group of caprone cable more than one, lay with removal process in because the variation in seawater flow field can make caprone cable twine, therefore, the rope centre also will equidistantly twine with adhesive tape 9.
As shown in Figure 2, caprone cable all adopts the fixing knot 6 of tent when being fixed in the shackle 4, and the characteristics of this knot are: the rope in the middle of when caprone cable bears enough big pulling force is disconnected earlier, rather than is fixed on and unloads the knot of buckling and break earlier.Therefore can calculate the disrumpent feelings needed pulling force of the caprone cable of sening as an envoy to, reduce the purpose that scientific instrument are lost thereby reach.
As shown in Figure 3; the utility model pulls the disrumpent feelings view of generation in the process at fishing boat; promptly after subsurface buoy lays, fishing boat or other factors cause buoyant material 1 and scientific instrument 2 by under the situations of scraping, along with the increase of pulling force can make this disrumpent feelings fender guard take place disrumpent feelings.When carrying out the design of submerged buoy system, the pulling force when rupture pull force should normally lay recovery greater than subsurface buoy, and, make this fender guard only just disrumpent feelings where necessary less than the net weight power of submerged buoy system in water.Promptly to consider suffered gravity and buoyancy in water such as the buoyant material of the subsurface buoy that lays and scientific instrument and anchor etc., calculate its net weight power,, just can make the disrumpent feelings fender guard of subsurface buoy take place disrumpent feelings when the pulling force of caprone cable during less than net weight power.When the size of caprone cable was chosen, then per share breaking force was fixed.According to whole submerged buoy system in water suffered net weight power and when disrumpent feelings relation between the required pulling force adjust the needed number of share of stock of caprone cable.Subsurface buoy lay with removal process in, if number of share of stock is very little, might cause caprone cable disrumpent feelings in advance, cause unnecessary loss.Because fisherman mistake is dragged for or other uncertain factor when causing subsurface buoy to be pulled, if number of share of stock is too many, whole subsurface buoy will be pulled, then the disrumpent feelings effect of out of reach.Therefore, correctly select the number of share of stock and the size of caprone cable, make the loss of buoyant material and scientific instrument drop to minimum according to submerged buoy system design-calculated actual needs.
