Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a mining device for mining four ingots of deep-sea gold, and a continuous mining device I equipped with a special E type removable bucket. For the past 15 years, deep-sea metal lumps have mainly been found at depths of 4,000 m to 6.
A nodule on the deep seabed at a depth of 1,000 m has attracted a lot of attention.
As a mining device, many methods such as suction pumps have been studied.

However, in recent years, the water depth has become shallower and the water depth is 800m to 200m.
Cobalt-rich manganese crusts (hereinafter referred to as crusts) distributed on 0 m seamounts and Gyo (flat top seamounts) have begun to attract attention. This is because the metal content of the crust is higher than previously thought, and the amount of metal present is extremely high.Continuous bucket mining, which allows mining even on the uneven seabed, is attracting renewed attention as a mining method. became.

Prior Art The present inventors previously disclosed patent application No. 8979 of 1960 (Patent Publication No. 23482 of 1971) and Patent Application No. 84864 of 1968 regarding a deep seabed metal lump continuous sampling device and its auxiliary device. (1972 Patent Application Publication No. 32829
1972 Patent Application No. 93181 (1978 Patent Application Publication No. 6242), 1978 Patent Application No. 916
6 (1972 Patent Application Publication No. 39361), 1972 Patent Application No. 95799 (1978 Patent Application Publication No. 48561), etc., and have been developing and putting these into practical use. Ta.

The IM conducted in the southeastern waters of Hawaii at a depth of 4,900 meters using the 2nd Kyokuyo Maru I (17,000 tons) in the summer of 1971 was the world's first mining experiment for four deep-sea gold ingots, and the seventh. The horizontal towing method shown in Figure 8 was tested. Based on the results, CNEXO in France proposed and tested the two-vessel towing method shown in Figure 8.

In addition, the inventors have explained 1.
．． Tests were conducted off the coast of Ogasawara in 1850.

There are three methods for the continuous bucket method, as shown in Figures 7 to 9 above. ing.

In all three methods, the endless rope R reaches the seabed and is hauled up by a fourth dredge on the seabed using a bucket Bi trowel.

The difference between the three methods is the separation of the two rope lines for ascending and descending (in Figure 7, the captain of the ship is
In the figure, the distance between two ships is separated by using the fluid resistance force of a separately attached resistance plate, etc. in FIG. 9.

Problems to be Solved by the Invention There are many problems to be solved in order to make such a continuous bucket a successful practical mining method. The first thing we experienced when conducting the experiment on the 2nd Kyokuyo-9 off the coast of Hawaii was the weakness of the slip ring where the bucket was suspended from a long, soft nylon rope line. In the experiment, there were many accidents where the slip ring broke, and when the rope (a covered iron collar) passed through the driving vehicle, it was subjected to strong force and was damaged. It was made by covering the rope with iron hardware and attaching a slip ring hardware to the groove.

Means and Function for Solving the Problems The present invention uses the following configuration as a means for solving the problems of the conventional methods.

(4) Specified interval of endless rope (e.g. 200
An iron connecting link is placed every m1 and connected to an enylon rope via a shackle.

(2) Nl is provided on the outer periphery of the connecting link, the lower end of the hook is hooked on the G, and the bucket is connected via the tow rope, and the hook is connected by a latch that is swingably provided on a part of the hook. Link E can be locked and unlocked.

(3) Before the first guide car that lifts the endless rope, grab the tow line of the bucket with a hoist from the ship, pass through the guide car, and after the hook is released from the connecting link, release the contents of the bucket inside the ship, and then On the other side, a clay/equipment with a hoist is provided on board to release the towline after the last guiding wheel has been lifted after the hook has been locked to the connecting link.

(4) The first guide wheel and the last guide wheel are connected to a base metal flea that slides within a semi-circular ring, so that the endless rope can move on a predetermined course passing through the center of the semi-circular ring on board the ship. In this way, the connecting link and the hook can be easily engaged and detached, and the endless rope can be circulated by the 2@multi-winding drive vehicle ζζ on board the ship.

(5) Embodiment in which wind power is used in addition to side thrusters, etc. as motive power for moving the collection vessel In the present invention, as shown in FIG. Connect tension lobes 3 and 3.

Continuous buckets that have been experimented with or devised so far have used a series of long nylon ropes; We have adopted a method of creating several colors that can be divided into two parts.However, this method uses rose and iron!
,! ! When the collar follows a car, there is a high risk of damage to the rope, so in order to guarantee long-term operation, it is safe to manufacture and connect this part with iron, and in the case of crust mining, this is considering the use of a connecting link 1 of 1114 times per 200 m. This 2 is shown in Figure 2 and Figure 3.
We will explain how to use the hook/detachable metal fittings for attaching and detaching the chain buckets 5, etc. 2 to the connecting links 1 every 00m.

In FIGS. 2 and 3, there is a connecting hole 4a at the lower end of the hook 4 that meets the groove t of the iron connecting link 1, and a tow line 6 with a chain bucket 5 suspended therethrough is connected to the shackle 7.
It is installed via. On the other hand, the tip of the hook 4 has a curved shape 4b. - There is a latch 8 loosely fastened with a bolt in the force support hole 4C, and a horizontal fastening rod 9 is held at the end of the latch 8 by a spring 10, and this latch 8 is connected to the gate in the direction of the arrow. When this force is applied to the rotation, the horizontal retainer 9 presses the spring 10 and the latch 9 closes at the bent portion 4b.
A horizontal retaining persimmon 9 is placed around the outside of the bending portion 4b to prevent the seven hooks 4 from coming off the groove of the connecting link 1 as shown in the figure. - To remove the hardware 8 from the blade, use a person or a robot (the yellow retaining rod 9 is removed by the spring 10).
Press to remove the bent part 4b. If you remove it from the lever, the hook 4 is free.] It can be removed manually (or by a robot) from the kari connecting link l. In this case, it is necessary to use another strong crane force to pull up the towline 6.

f2C Oh, the above explanation shows implementation ◇11, and there may be another design for the hook and detachable fitting, but by installing this iron connecting link part lζ, you can prevent damage to the rope and attach it to the bucket. The dog is effective in improving the function of attaching and detaching the bucket to eliminate passing through the drive unit with the bucket attached.

Next, the arrangement and operation of Plan P'3 car on board [Kotsuki Fig. 4,
This will be explained from Figure 5. Figure 4 is a perspective view showing the arrangement of guide wheels in the stern of the single-vessel towing system shown in Figure 9, and Figure 5 is a side view of the first guide wheel. . As shown in FIGS. 4 and 5, the inclination and direction of the rope 11 brought up from the sea vary depending on sea conditions and operating conditions. The structure of the rope 11 and the first structure for attaching the bucket 5 are as described above. Therefore, in order to safely bring the rope into the ship, it is necessary to correctly orient the intake guide wheel 12 in the direction of the rope to prevent the rope from turning +ptF.

For this purpose, the base metal fitting 13 supporting the intake guide wheel 12 tightly fits and slides on the semicircular ring 14, so that the rope 11 from the intake guide wheel 12 to the next guide wheel 15 is always connected to the semicircular ring 14. 14, which passes through the center of the circle. Arranging the rope 11 along a fixed line in this manner facilitates the work of removing the hook/detachable hardware from the rope connection link 1, making it possible to use it as a robot.

The rope passing through the guide wheel 15 is wound multiple times around multiple winding drums 17 and 18 driven by a motor 16, and is driven with sufficient frictional force. By using this multi-drive vehicle,
The size of the driving part can be made much smaller. The rope that has passed through the multi-drive vehicle is sent out via the guide vehicle 19 to the guide vehicle 2.
Guided by 0, they go into the sea.

The base hardware 21 of the delivery guide wheel 20 is engaged with the semi-circular ring 22 and slides thereon, thereby holding the rope so that it always passes through the center of the semi-circular circle ff122.

From this lobe line, in order to remove the chain/bucket 5, the chain/bucket 5 is placed on one side of the deck. When the chain bucket 5 comes close to the intake guide car 12, it is hoisted up by grasping the tow rope 6, and while canceling the weight of the chain bucket 5, the connecting link part of the rope is introduced into the ship. Once the direction of the rope is fixed, the next position (remove the trowel hook and detachable hardware), take the removed chain bucket 5 into the ship, and take out the crust inside.The empty chain bucket 5 is placed on the opposite side It can be attached by reattaching the hook/detachable hardware to the connecting link using the crane pillar 27, crane horizontal bar 28, hoist 29, etc. attached to the deck, and then releasing the grip on the chain/bucket tow rope. As a result of this improvement, the drive device can be made sufficiently smaller and lighter, making economical mining possible.

This continuous sampling device collects 2,000 samples from crust deposits on seamounts.
According to a trial calculation in the case of mining at a production rate of 7) tons/day, the power required for the rope is approximately 100 tons.
It is estimated that a driving horsepower of 1500 PS is required. However, to propel the ship sideways or forward beyond this rope, a thrust of at least 50 tons is required.
Propeller (when trying to get this thrust
Assuming 13kg thrust per PS, 4000
It is estimated that PS version requires 1 solid horsepower. C is equivalent to 2.6 times the driving horsepower for mining, and per IPS-h,
If it costs 10 yen per day, it would cost 1 million yen per day to propel this ship. Although it is a hot theory that equipment such as side thrusters is necessary, it is possible to achieve the economic efficiency of deep-sea mining by utilizing the wind power of trade winds as much as possible as the power for the ship's lateral movement. Expected to be effective.

FIG. 6 shows an example in which mining of a crust deposit in a relatively shallow sea is targeted at t9. The water depth of the deposit is 800m to 1800m.
Since it is relatively shallow, the single-vessel towing method shown in Figure 1 can be quite successful. The distance between the intake guide wheel 12 and the delivery guide wheel 20 is set at 30 to 70 m, assuming the water depth is approximately 1725 m.

If this were a normal ship, it would be rrrj another 2! Lrλ is the interval on the deck where the sound can be heard.

On the other hand, the bow and stern of the ship (here are the side thrusters 30 and 31)
is attached and the ship is moved laterally, but when the crust enters the chain no. 5 and begins to be lifted, it becomes necessary to add a large lateral thrust. To counter this, the ship S is equipped with a sail or a plate sail 32 installed on the ship, and is operated as unmanned as possible to adjust the area and appropriately receive the wind force and move in the lateral force direction. Furthermore, by adjusting the angle of the plate sail 32, it is possible to move it in an oblique direction as required.

By combining the above effects of the invention, the deep seabed metal lump continuous sampling device with a detachable bucket uses wind power to move the ship in the lateral direction, and connects detachable chain buckets to ropes with steel connections at intervals. By installing this link, it is possible to mine the crust on the ocean floor economically and while maintaining a long operating life without damaging the rope.
