When the submarine cable is laid, workers need to go into the sea to clean the laying path of the submarine cable, and mainly clean obstacles such as fishing nets, abandoned cables and the like.
When the obstacle removing device of the embodiment is used for removing obstacles such as fishing nets and abandoned cables, the following operations are required: (1) Firstly, a worker twists the adjusting screw 85 in the direction outside the cleaning cage 5 (namely, twists the adjusting screw 85 downwards), so that the adjusting screw 85 pulls one adjusting cylinder 82 downwards, and because two adjacent adjusting cylinders 82 are connected through the adjusting connecting rod 83, all the adjusting cylinders 82 can be pulled downwards, so that the included angle between the outer wall of each adjusting cylinder 82 and the adjusting driving rod 84 is increased, and therefore the adjusting driving rod 84 pushes the resistance increasing spine 7 outwards the cleaning cage 5, so that the resistance increasing spine 7 is in the state of exposing the cleaning cage 5, see fig. 4-7, and in this state, the cleaning cage 5 can hook obstacles such as fishing nets, waste cables and the like more easily. (2) Then the workman starts driving motor 61, and driving motor 61's output shaft drives drive shaft 62 and rotates, and drive shaft 62 drives clearance cage 5 and rotates, and the clearance cage 5 that is rotating can be twined on clearance cage 5 by obstacles such as fishing net, abandonment cable that increase resistance thorn 7 hooked. (3) The workman rotates to receive and release and rotates seat 31, changes support frame 4 and clearance cage 5 to the sea water top, and the workman starts to receive and release motor 34 reversal, releases haulage rope 2, puts in the sea with clearance cage 5 on support frame 4, the support frame 4 in the sea water and clearance cage 5 can get up the rolling of obstacles such as fishing net, abandonment cable on the submarine cable laying route along with the navigation of construction ship 1, and the realization is cleared up obstacles.
After the cleaning operation is completed, workers on the construction ship 1 can start the retraction motor 34 to rotate positively to wind the traction rope 2, the support frame 4 is lifted out of the sea, and the cleaning cage 5 arranged on the support frame 4 and obstacles such as fishing nets, waste cables and the like wound on the cleaning cage 5 are also lifted out of the sea.
When obstacles such as fishing nets, waste cables and the like collected on the cleaning cage 5 need to be dismounted, a worker needs to screw the adjusting screw 85 in the direction inside the cleaning cage 5 (namely, the adjusting screw 85 is screwed upwards), so that the included angle between the outer wall of the adjusting cylinder 82 and the adjusting driving rod 84 is reduced, the adjusting driving rod 84 pulls the resistance-increasing spine 7 into the cleaning cage 5, the resistance-increasing spine 7 is retracted into the cleaning cage 5, in this state, the obstacles such as the fishing nets, the waste cables and the like wound on the surface of the cleaning cage 5 can not be hooked by the resistance-increasing spine 7 any more, and the obstacles such as the fishing nets, the waste cables and the like wound on the cleaning cage 5 can be rolled off from the cleaning cage 5 by the worker more conveniently.
Through the above process, it can be known that: in the clearance sacrifice device of this embodiment, clearance cage 5 and increase and hinder thorn 7 and adjustment mechanism 8's cooperation use, can be in clearance fishing net, when barriers such as abandonment cable, utilize and stretch out clearance cage 5 outside increase and hinder thorn 7 hook and live fishing net, barriers such as abandonment cable, prevent that the barriers from escaping, improve and catch the fastness, still can utilize the rotation of clearance cage 5, the winding rolling of the barrier that will be increased and hinder thorn 7 hook and live is on clearance cage 5, realize the operation of mechanical clearance sacrifice, need not the workman and go to the sea in person, be favorable to improving workman clearance operation security, and still be favorable to improving clearance operating efficiency.
In addition, in the obstacle removing device of the embodiment, when the obstacles need to be removed, the resistance-increasing thorns 7 can be retracted into the cleaning cage 5 by the adjusting mechanism 8, so that the obstacles on the cleaning cage 5 can be rolled off conveniently. Thereby the device of removing obstacles of this embodiment not only conveniently twines obstacles such as fishing net, abandonment cable and collects, still conveniently unloads obstacles such as fishing net, abandonment cable to conveniently put in the device of removing obstacles once more and put into the sea operation, be favorable to further improving the operating efficiency of removing obstacles.
Surprisingly, in the obstacle clearing device of the embodiment, when the resistance-increasing barbs 7 extend out of the clearing cage 5, the resistance-increasing barbs can be used for hooking obstacles such as fishing nets, abandoned cables and the like floating in the sea, and when the resistance-increasing barbs 7 retract into the clearing cage 5, the obstacles can be conveniently detached, so that the obstacles cannot be greatly damaged whether caught or detached, the integrity of the obstacles is protected, the obstacles can be conveniently recycled, and the resource saving is facilitated. For example, the recovery of the waste cable usually requires stripping the insulation skin on the surface of the cable and then performing other processes, and if the waste cable is damaged, for example, the waste cable is recovered by grinding, it is inconvenient to strip the insulation skin, and thus the waste cable is inconvenient to recover.
In addition, in the device of removing obstacles of this embodiment, clearance cage 5 is fretwork tubular construction, not only can reduce the moving resistance in the sea water, can also let the silt that gets into in the clearance cage 5 in time be washed away by the sea water, prevent that silt from piling up and hindering adjustment mechanism 8's action in clearance cage 5, thereby be favorable to ensureing that adjustment mechanism 8 is to increasing the smooth regulation of hindering thorn 7, thereby the reliability of use of this embodiment device of removing obstacles has been improved, the convenient device of removing obstacles of this embodiment is maintained, be favorable to improving maintenance efficiency.
Furthermore, in the clearance device of this embodiment, adjustment mechanism 8 for adjusting increase and hinder thorn 7 and advance and retreat clearance cage 5 is pure mechanical structure, has reduced the use of electrical component to reduce the probability of electrical component trouble, more be favorable to improving the reliability, more conveniently maintain, be favorable to further improving maintenance efficiency.
Example 2:
in this embodiment 2, a further improvement is made on the basis of embodiment 1:
as shown in fig. 4 to 6, in the obstacle removing device for laying a submarine cable according to embodiment 2, a support bracket 41 is attached to the support frame 4 on a side close to the cleaning cage 5, a support bracket 411 is provided on the support bracket 41, a support ring 52 is attached to the periphery of the end of the cleaning cage 5, and the support ring 52 is rotatably fitted to the support groove 411. When the cleaning cage 5 is driven to rotate by the driving motor 61 in the driving mechanism 6, the bearing ring 52 at the end of the cleaning cage 5 can rotate in the bearing groove 411 of the bearing seat 41. So set up, can improve the support intensity to clearance cage 5 to let the obstacles removing device more reliable and more stable, improved the stability and the security of obstacles removing operation.
Example 3:
in this embodiment 3, on the basis of embodiment 1 or embodiment 2, a further improvement is made:
as shown in fig. 9 to 15, the obstacle clearing device for laying an ocean bottom cable according to embodiment 3 further includes an expansion mechanism 9, and the expansion mechanism 9 includes a first expansion limiting portion 91, a second expansion limiting portion 92, an expansion link 93, and an expansion stay 94. The resistance increasing spine 7 is provided with a first expansion limiting part 91 and a second expansion limiting part 92 at one end close to the adjusting drive rod 84, and the first expansion limiting part 91 is closer to the adjusting drive rod 84 than the second expansion limiting part 92. One end of the expansion link 93 is provided with an expansion slide hole 931, and the expansion slide hole 931 is in sliding fit with the part of the resistance-increasing thorn 7 between the first expansion limiting part 91 and the second expansion limiting part 92. The other end of expansion connecting rod 93 stretches out from the fretwork hole department of clearance cage 5, and expansion extension board 94 is installed to the one end that expansion connecting rod 93 stretches out clearance cage 5, and expansion extension board 94 preferably adopts the arc for expansion extension board 94 can more laminate the surface of clearance cage 5.
The expanding mechanism 9 can adapt to the action of the adjusting mechanism 8 for adjusting the resistance increasing thorn 7. When the adjusting mechanism 8 adjusts the resistance-increasing barbs 7 to extend out of the cleaning cage 5, the expanding mechanism 9 can perform an expanding action, that is, the expanding support plate 94 in the expanding mechanism 9 can leave the cleaning cage 5; when the adjusting mechanism 8 adjusts the resistance-increasing barbs 7 to retract into the cleaning cage 5, the expanding mechanism 9 can perform a retracting action, i.e., the expanding support plates 94 in the expanding mechanism 9 can approach the cleaning cage 5.
The effect of the above-mentioned action is, first, when resistance-increasing thorn 7 stretches out clearance cage 5, expansion extension board 94 leaves clearance cage 5, can let obstacles such as fishing net, abandonment cable twine on expansion extension board 94, rather than directly twine on clearance cage 5, because expansion extension board 94 leaves clearance cage 5, so the outer diameter of the tubular structure that is enclosed by all expansion extension boards 94 is bigger than the external diameter of clearance cage 5, has increased the volume of clearance cage 5 in other words, has increased the area that clearance cage 5 twined the obstacle in other words. Thereby being beneficial to increasing the resistance of winding obstacles and improving the firm reliability of collecting and cleaning the obstacles.
Secondly, after the volume and the area of increase clearance cage 5, can increase the quantity of collecting the winding of barrier to in once only twine more barriers, reduce the number of times of unloading, thereby be favorable to further improving clearance efficiency.
Thirdly, increasing resistance thorn 7 withdrawal clearance cage 5, when expansion extension board 94 is close to clearance cage 5, compare with the expansion state, reduced the volume and the area of clearance cage 5 in other words to be favorable to letting the barrier that twines be in loose state, let the barrier that twines on the expansion extension board 94 in the clearance cage 5 outside drop more easily, reduced the degree of difficulty of unloading, reduced the manual physical demands when unloading of workman, be favorable to improving the efficiency of unloading, reduce intensity of labour.
Fourthly, because the obstacles are in a loose state after the volume and the area of the cleaning cage 5 are reduced, even workers do not need to manually take off the obstacles, the obstacles in the loose state can fall off under the action of the self gravity, and the labor intensity of the workers is further reduced.
Specifically, the expanding mechanism 9 can adapt to the adjusting mechanism 8 to adjust the resistance increasing spine 7:
the first action is as follows: the workman revolves adjusting screw 85 to the outside direction of clearance cage 5 soon (i.e. revolves adjusting screw 85 downwards) for adjusting screw 85 stimulates one down and adjusts a section of thick bamboo 82, because two adjacent regulation section of thick bamboos 82 are connected through adjusting connecting rod 83, so all regulation section of thick bamboos 82 can both obtain decurrent pulling, make the outer wall of adjusting a section of thick bamboo 82 and adjust the contained angle between the actuating lever 84 and increase, thereby make and adjust actuating lever 84 will increase and hinder thorn 7 and promote outside clearance cage 5, make and increase and hinder thorn 7 and stretch out outside clearance cage 5 gradually.
In the process that the resistance increasing spine 7 gradually extends out of the cleaning cage 5, the first expansion limiting part 91 and the second expansion limiting part 92 which are positioned on the resistance increasing spine 7 move together with the resistance increasing spine 7, so that the first expansion limiting part 91 pushes the expansion connecting rod 93, the expansion connecting rod 93 also gradually extends out of the cleaning cage 5, the expansion connecting rod 93 extending out of the cleaning cage 5 pushes the expansion supporting plate 94, and the expansion supporting plate 94 gradually leaves the cleaning cage 5. See fig. 14 to 15 and further to fig. 12.
Finally, the obstacle clearing device of the embodiment is in a state as shown in fig. 12, in this state, the expansion support plate 94 leaves the clearing cage 5, which is equivalent to enlarging the outer diameter of the clearing cage 5, enlarging the volume and area of the clearing cage 5, and the resistance increasing stabs 7 still protrude out of the expansion support plate 94, so that the function of the resistance increasing stabs 7 in the embodiment 1 for hooking obstacles such as fishing nets, abandoned cables and the like is maintained.
