Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a collection device for collecting mineral resources, mud, rocks, and other underwater deposits deposited on the bottom of the water.

[Conventional technology]

As shown in the system diagram of FIG. 3, this type of underwater object collecting device conventionally pumps high-pressure water using a water pump device 24 consisting of a high-head water pump 20 and piping 22 mounted on a floating collecting boat 16. The water is sent to a collection jet pump 8 installed near the water bottom, which is driven to suck up the bottom sediment 4a deposited on the water bottom 2 together with the water 14, and transport it to the collection boat 16 on the water by hydraulic transport in the piping 34. Loaded on board,
The water bottom sediment 4C and the water 14 were separated on the ship, the separated water 14 was drained, and the water bottom sediment 4C was collected on the ship.

[Problem to be solved by the invention]

However, if the depth to the water bottom 2 is deep, the piping 22
is longer, it is necessary to install several stages of collection jet pumps 8 in series depending on the depth, and the efficiency of the jet pump itself is low at about 17'3 compared to a normal pump.
There were problems in that the operating cost was high, the equipment was complex, expensive, and difficult to handle, and it could not be applied to deep water bottoms.

Regarding the collection of underwater sediments, the present invention requires only one jet pump for collection, which saves labor and energy in the collection work, and can be applied to deep underwater sites. [Means for Solving Problem C1111 Aiming to Provide a Location] In order to solve the above-mentioned problem, the present invention provides a robot vehicle that can freely move on the water bottom at a place where bottom sediment is collected;
σ) A collection mechanism that is attached to the robot vehicle and has a collection suction port facing the water bottom sediment to be collected, and a collection mechanism that is detachably attached to the robot vehicle to separate the transported water bottom sediment from the water. The present invention includes a cartridge-type case that is stored and stored and transported by a transport means provided on a water-borne collection vessel, and a supply device that supplies driving energy to the collection mechanism.

[For production]

The present invention includes a robot vehicle that can freely move on the water bottom at a place where bottom sediment is collected, a collection mechanism such as a collection jet pump is attached to the robot vehicle, and a cartridge type case is detachably attached to the robot vehicle. First, the bottom sediment should be collected in a cartridge-type case using an upper blade of a robot vehicle near the bottom of the water, and the stored and accumulated bottom sediment should be transported in the cartridge-type case by means of transportation such as a crane on a collection vessel on the water. As a result, the functions of the part that collects and transports the bottom sediments are separated, so that only one jet pump is required for collecting and transporting the sediment (which improves the transport efficiency from near the bottom of the water to the collecting boat on the water, and reduces energy consumption for collection. It is possible to save on the amount of water and labor required for collecting work, and it is also possible to perform collecting work at deeper depths than before.

〔Example〕

An embodiment of the present invention will be described with reference to a system diagram in FIG. 1 and a sectional view around the robot vehicle 6 in FIG. 2. Mineral resources deposited on the bottom 2 and mud for dredging.

A robot vehicle 6 is provided which can freely move on the water bottom 2 at a place where bottom sediments 4a such as rocks are collected.

A collection mechanism 8 such as a collection jet pump is attached to this robot vehicle 6, and this collection mechanism 8 has a collection suction port 1.
0 faces the bottom sediment 4a to be collected. Further, the robot vehicle 6 is provided with a cartridge type case 12 which is detachably attached. This cartridge type case 12 stores and accumulates the water bottom sediment 4b transported together with the water 14 from the collection mechanism 8, and the water 14 is temporarily separated in the cartridge type case 12. When the storage and accumulation of the underwater sediment 4b is completed, the cartridge-type case 12 is transferred to the collection boat 1 by means of transportation 18 such as a crane or lifting device provided on the collection boat 16 on the water.
6, the bottom sediment 4C is transferred onto the collection boat 16, and the empty cartridge type case 12 is lowered and placed on the robot vehicle 6, and the collection work is repeated.

The collection vessel 16 is equipped with a water pump 20, piping 22, etc., which sucks up the water 14 and turns it into high-pressure water, which is then sent to the collection mechanism 8.
A supply device 24 is provided for supplying drive energy for the collection mechanism 8, such as a water pump device for supplying and driving a collection jet pump.

In addition to what is shown in FIG. 1, the water pump 20 may be attached to the robot vehicle 6, and the supply device 24 may be used to supply power using an electric cable instead of the piping 22. In this case, handling becomes easier. Further, instead of the collection jet pump, a pump such as a sand pump can be used as the collection mechanism 8, and the collection mechanism 8 can be operated by supplying electric power with an electric cable.

In the cross-sectional view of the robot car 6 in FIG.
is powered by power from the collection vessel 16 via its own battery or an electric cable (not shown), observes its surroundings with a visual sensor (not shown), and transmits and receives signals to the collection vessel 16. Remotely controlled from 16,
It can freely move on the water bottom 2 where the water bottom sediment 4a is collected.

The cartridge-type case 12 is a hollow container having a cylindrical shape as a whole, with the left and right end faces connected by strips, and a mesh sieve of desired dimensions with "sieve openings" attached to the body. It is provided with a handle 26 for cargo handling, and a hole 12a for receiving bottom sediment 4a is provided on the left end face in FIG. The Type 1779 case 12 is transported between the robot vehicle 6 and the collection ship 16 by a transport means 18 such as a crane on the collection ship 16. A hook 32 with a visual sensor 30, such as a camera, engages the handle 26. The seven hooks 32 can be freely selected to remain engaged with the handle 26 during the collection operation, or to be disengaged as an automated hook except when loading the cartridge-type case 12.

Since the robot vehicle 6 is provided with a guide 6a at the top, the cartridge type case 12 can be easily inserted.

The apparatus of the present invention having the above-mentioned structure removes the underwater sediment 4a.
As shown in Fig. 1 and Fig. 2, K, which collects sediments, as shown in Figs. Mechanism 8. The pipes 22 and the like are arranged as shown in FIG. 1, and the empty cartridge case 12 is transported from the collection boat 16 toward the robot vehicle 6 by the transport means 18 by engaging the handle 26 and the seven hooks 32. . Cartridge type case 12
When the vehicle approaches the robot vehicle 6, move the transport means 18 or the robot vehicle to a position where the cartridge-type case 12 can be easily inserted while visually checking with the visual sensor 30, and insert the empty cartridge into the robot vehicle 6 using the guide 6a. Insert the formula case 12.

(2) If the hook 32 is an automated hook, the handle 2
6, the conveying means 18 can be directed to other tasks. If it is not an automation hook, leave it as a bond.

(3) The collection mechanism 8 is driven by the supply device 24 to collect the bottom sediment 4a into the cartridge type case 12.

In the one shown in FIG. 1, a water pump device is constructed from a water bonder 20 and piping 22 as a supply device 24, and a water pump 2
0, the water 14 is sucked up and made into high-pressure water, and this high-pressure water is guided to the collection jet pump of the collection mechanism 8 through the piping 22 to drive it. The bottom sediment 4a of the water bottom 2 is sucked in from the collection suction port 10 together with the water 14 into the receiving hole 12.
a, the water is transported to the cartridge case 12, and the water 14
is discharged into the water from the "sieve opening" of the cartridge type case 12, and the water bottom sediment 4b is filtered and separated and stored and accumulated in the cartridge type case 12. During this time, the robot vehicle 6 freely moves on the water bottom 2 and collects the water bottom sediment 4a over a wide area.

If the "opening of the sieve mesh" is selected in advance, objects smaller than this size will be discharged together with the water 14, so that the bottom sediment 4b can be naturally classified according to size.

(4) When the bottom sediment 4b is stored and accumulated in the cartridge type case 12 and becomes full, the collection mechanism 8 is stopped, and if the seven hooks 32 are still engaged with the handles 26, the automated hooks are In this case, while observing with the visual sensor 30, engage the hook 32 with the handle 26 and transport the cartridge type case 12 onto the collection boat 16 using the transport means 18, and remove the bottom sediment 4b in the cartridge type case 12. is discharged onto the collection vessel 16 as bottom sediment 4C.

(5) Insert the empty cartridge type case 12 into the robot vehicle 6 again as in (1) above, and repeat the collection operation.

According to the present invention, a collection mechanism 8 such as a collection jet pump is provided on a robot vehicle 6 that can freely move on the water bottom, and a cartridge type case 12 is detachably attached to the robot vehicle 6.
The bottom sediments 4b are collected therein, stored and accumulated, and then transported onto the collection boat 16 by a transportation means 18 such as a crane and discharged onto the ship as bottom sediments 4c. Since the collection part and the transport part are functionally separated, the collection mechanism 8, for example, the jet pump for collection, only needs to have one stage, and the supply device ft24 that drives it, for example, the water pump device, can also be of small capacity. Since the transportation from the to the collection vessel 16 on the water is carried out by an efficient transportation means 18 such as a crane, it is possible to save energy as a whole. Another gathering machine! It is easy to handle because only one stage is required in step 8, and the collection work can be labor-saving.Furthermore, the cartridge-type case 12 allows you to select the ``sieve opening'' in advance and insert a desired filter. As a result, the size of the bottom sediment 4b can be classified naturally during the collection work.

〔Effect of the invention〕

The present invention provides a method for collecting bottom sediments from the bottom of the water and transporting them onto a collection vessel on the water. Because the functions of the part that collects and transports the sediment are separated, the collecting mechanism can be configured in one stage, and the feeding device that drives it can also be a small-sized tray, which saves energy as a whole and makes it easy to handle and collect. It can save labor. Furthermore, since the method uses a transportation means such as a crane, it is possible to collect water foot deposits at deeper depths than previously possible. Also, cartridge type case 0) "Flui eye opening"
By selecting in advance or interpolating a desired filter, it is possible to naturally classify the size of underwater sediment during collection work.
