Description

Ship for harvesting kelp from ship side

Technical Field

The utility model relates to a kelp is gathered ship particularly, is a ship of gathering kelp from boats and ships topside.

Background

At present, a kelp harvesting ship provided with a harvester is generally arranged at the bow of the ship, and kelp is harvested longitudinally along the ship, such as the harvesting mode of a ship 6 in figure 1.

Such harvesting mode has 3 disadvantages:

first, the transverse water-blocking channel. As shown in fig. 1, the basic culture unit of the kelp culture zone is composed of two parallel ropes and a plurality of parallel seedling ropes. The two boom ropes are about 70m long respectively, the distance between the two boom ropes is about 5m-6m, the two boom ropes are tied and buckled on the peg stake fixed in the sea, and the distance between the two boom ropes on the two boom ropes is about 1.5 m. Each culture unit with the kelp seedlings clamped on the seedling rope sinks and floats in the seawater by virtue of the floating balls tied on the boom rope. The plurality of units are arranged together in a side-by-side manner to form a floating raft group, and the distance between the floating raft groups is wider than the distance between the boom ropes so as to facilitate the working ship to pass between the floating raft groups. As the length-width ratio of the fishing boat is generally 3-4, the influence of the length of the boat to shield the water channel is much larger during longitudinal collection than during transverse collection, as shown in figure 1, so that longitudinal collection is not beneficial to navigation of other operation ships and influences the safety of the ships.

In addition, in the operation mode shown in fig. 1, when the harvesting ship is about to leave the water channel, the ship must be firstly rotated until the ship body is approximately parallel to the water channel, and the turning radius of the ship is longer than the ship length, so that the rotation process also affects the navigation safety of other ships in the water channel. In the operation mode shown in fig. 2, the ship is already nearly parallel to the water channel, and large-angle rotation does not exist, so that the influence on other sailing ships is small.

Secondly, for avoiding the higher harvester of bow portion to influence the navigation field of vision, satisfy the relevant requirement of boats and ships rule, just need set up higher superstructure and/or deck room, this can lead to the focus of boats and ships to rise to and great wind pressure arm, it is unfavorable to boats and ships stability, influence boats and ships safety.

Thirdly, the harvester is arranged at the head and the tail of the ship, is far away from the gravity center of the ship, and needs more ballast for balancing so as to adjust the navigation state.

Further, the first crane 40 and the second crane 41 are of the same type and are symmetrically arranged on the main hull 10 along the longitudinal centerline of the hull.

A ship for harvesting kelp from the side of a ship comprises a main hull 10; a cab 11 near the bow; a hangar 12 near the stern of the ship; a harvester 20 transversely arranged near the middle of the main hull; a towing rope 21 which is installed on the harvester 20 and is obliquely dragged upwards from the side to the inside; a kelp tip collecting compartment 13 located in front of the harvester and a kelp body collecting compartment 14 located behind the harvester; a first conveyor belt 30 for transporting the kelp tips, which is placed under the harvester 20, and is operated forward, and a second conveyor belt 31 for transporting the kelp body, which is operated backward; the horizontal projection of the dragging direction of the dragging rope 21 attached to the harvester 20, the conveying direction of the seedling rope 3 on the harvester 20 and the conveying direction of the conveying chain 22 is vertical to the side.

A method of operating the vessel described above, comprising the steps of: the harvesting ship 10 runs along the water channel between the adjacent floating raft units, runs to the side of one floating raft unit, stops running, and puts the dragging rope 21 on the harvester 20 to the other end of the boom rope 2 in the floating raft group; then, the seedling ropes 3 are unhooked from the boom ropes 2, and the unhooked seedling ropes 3 are tied to the corresponding drag ropes 21 based on the distance between the original seedling ropes, so that the drag ropes 21 replace the boom ropes 2; starting the harvester 20, gradually pulling the drag rope 21 towards the other side of the main hull 10, when the seedling rope 3 is pulled to the outboard side, continuously pulling the seedling rope 3 to the inboard side by the drag rope 21, or releasing the seedling rope 3 from the drag rope 21, respectively fixing the two ends of the released seedling rope 3 on the conveying chains 22 at the two sides of the harvester 20, conveying the seedling rope 3 tied with the kelp 5 to the inboard side by replacing the drag rope 21 with the conveying chains 22, and cutting off the kelp tips by the cutting knives when the kelp 5 meets the cutting knives with lower positions in the harvester 20; the cut kelp chips fall onto the first conveyor belt 30 and are conveyed by the first conveyor belt 30 into the kelp chip collection compartment 13; while the first conveyor belt 30 carries the kelp tips, the seedling rope 3 is continuously pulled to the other side of the main hull 10, and when the kelp 5 is pulled above the second conveyor belt 31 and meets a cutter blade positioned higher in the harvester 20, the kelp 5 is cut and falls onto the second conveyor belt 31 and is conveyed by the second conveyor belt 31 into the kelp body collection compartment 14; the partition plate 32 partitions the first and second conveyors so that the kelp tips and/or the kelp body do not fall onto the adjacent conveyors.

Further, after enough kelp is loaded in the net bags on the two conveyor belts, and the kelp boat 10 runs out of the water channel between the raft units, the net bags with the same weight are lifted by the cranes at the two sides at the same time, and the net bags are transferred to the transport boats which are positioned at the two sides of the kelp boat 10 and operate correspondingly to the

cranes

40 and 41.

The beneficial effects of the utility model reside in that:

1) in the operation, the influence on the shielding of the water channel is small, thereby being beneficial to the navigation safety;

2) the harvester is not arranged at the front part of the ship body, so that a front cab can be arranged, and the problem of sight line obstruction is solved;

3) multiple harvesters can be arranged in parallel, which is beneficial to improving the harvesting efficiency. Description of the drawings: taking a kelp cutting boat with the length of about 21 meters and the width of about 6 meters as an example, only one cutting machine can be arranged in the longitudinal direction (in the prior art), when the kelp cutting boat is arranged in the transverse direction, the boat length is increased to about 30 meters, the boat width is changed to about 6.6 meters, the length-width ratio is enlarged from 3.5 to 4.5, and the enlargement of about 0.6 meter is within the range of the length-width ratio of a conventional fishing boat, and the water channel between floating rafts is smaller. In contrast, to provide two harvesters, the length to width ratio of the longitudinally arranged harvesting vessel decreases from 3.5 to 1.6 after increasing the width to about 13 m, and the drag increases significantly. And compared with the water channel between the floating raft groups, the increase of more than 6 meters is too large during navigation.

4) Because the two cranes have the same model, symmetrical arrangement positions and substantially equal and synchronous lifting weight, the kelp harvesting ship cannot generate larger transverse inclination due to slight difference of lifting moment, thereby further reducing the operation risk.

conveyor belts

30 and 31 disposed below the harvester 20 for carrying and transporting the cut kelp tips and the kelp body, respectively, to the kelp tip collecting compartment 13 and the kelp body collecting compartment 14; the projections of the horizontal plane of the dragging rope 21 attached to the harvester 20, the transporting direction of the seedling rope 3 on the harvester 20, and the transporting direction of the transporting chain 22 are perpendicular to the board side, and are not in a straight line with or parallel to the transporting directions of the

conveyor belts

30 and 31, but form a break angle which can be an acute angle, a right angle or an obtuse angle.

In harvesting, after the harvesting vessel 10 runs to the position of the vessel 7 in fig. 2, the navigation is stopped, and with reference to fig. 3-5, the two hauling ropes 21 on the harvester 20 are placed to the other ends of the boom ropes 2 in the floating raft unit, and then the seedling ropes 3 are unhooked from the boom ropes 2, and the unhooked seedling ropes 3 are tied to the corresponding hauling ropes 21 based on the original seedling rope spacing, so that the hauling ropes 21 replace the boom ropes 2. Then starting the harvester 20, gradually pulling the drag rope 21 to the starboard direction of the main hull 10, when the seedling rope 3 is pulled to the outboard side, continuously pulling the seedling rope 3 to the inboard side by the drag rope 21, or separating the seedling rope 3 from the drag rope 21, respectively fixing the two ends of the separated seedling rope 3 on the conveying chains 22 at the two sides of the harvester 20, conveying the seedling rope 3 tied with the kelp 5 to the inboard side by replacing the drag rope 21 with the conveying chains 22, and cutting off the kelp tips by the cutting knives when the kelp 5 meets the cutting knife with a lower position in the harvester 20; the cut kelp tips fall onto the conveyor belt 30 and are conveyed by the conveyor belt 30 into the net bag in the kelp tip collection compartment 13; while the kelp tip is carried by the conveyor belt 13, the seedling line 3 is continuously pulled to the starboard side of the main hull 10, and when the kelp 5 is pulled above the conveyor belt 31 and encounters a cutter positioned higher in the harvester 20, the kelp 5 is cut and falls onto the conveyor belt 31 and is conveyed by the conveyor belt 31 into the bag in the kelp body collection compartment 14.
