The present invention relates to the creation of a device and method for determining position, and more specifically the present invention relates to the creation of a device and method for determining the position of two layers with different permeability.

Underwater mountain harvesters can extract material on the seabed and transport this material to the FPU operating on the surface of the sea. Mountain harvesters usually work without staff and managed POI by one or several are in the process vessel operators who receive the management information from various sensors mounted on the mining machine.

Underwater mining of alluvial diamonds, these diamonds are usually found in the layer of diamond-bearing gravel, which lies on an empty rock barren clay or on the soles of clay. One of the main problems associated with carrying out the extraction under these conditions, is the difficulty to control the depth of the knife or excavator bucket. If the knife is not deep enough, there is a danger that part of diamondiferous gravel will not be produced. On the other hand, if the knife is too deep, it will produce excess clay. This clay is then no need to be transported on n the surface, where it creates the possibility of fouling of the process equipment and reduces the efficiency of the production process.

The first objective of the present invention is to provide a device and method for determining the position of two layers with different permeability.

Another objective of the present invention is to provide a device and method for determining the position relative to the diamond-bearing gravel and soles of clay, so that the knife mountain harvester could be kept at an optimal level directly below the boundary surface between diamondiferous gravel and soles of clay.

The device can be combined with the extraction tool material mining combine, so that the depth of the location of extraction tool material relative to the two layers could be set by a signal from the device for determining the position.

The issue or issues can be directed downward relative to the direction of movement of the mining machine. Additionally or alternatively issue or issues can be directed in the lateral direction relative to the direction of movement of the mining machine.

In accordance with another aspect of the present invention mountain harvester includes extraction tool material, which contains the above-described device, combined with the extraction tool material so that the depth of the location of the extraction tool material relative to the two layers can be set by a signal from the device for determining the position.

In accordance with another aspect of the present invention mountain harvester includes among the means of extraction of material, designed for the extraction of material in the upper layer, located on the lower layer having a permeability that is different from the permeability of the upper layer, and the extraction tool material has mounted thereon a housing having at least one release fluid through which can be released fluid, the fluid is supplied to the release of fluid through the pipeline, which contains a measurement tool designed to measure the flow and/or pressure of the fluid in the pipeline, in order to determine which of the two layers is the issue, that it was possible to set the position of the extraction tool material relative to two layers.

In accordance with another aspect of the present invention proposes a method of determining the position in two layers with different permeability, which includes the following operations: applying a liquid to at least one issue, situated in layers, measurement of flow and/or fluid pressure and positioning in two layers on the basis of the measured flow rate and/or pressure.

The method can include the operation of releasing the fluid through the issue down into layers. Additionally or alternatively, the method can include the operation of releasing the fluid through the production of mainly parallel to the layers.

The way the advantages to the public includes the operation of the fluid supply to many editions, mounted with clearance on top of each other.

The method can include the operation of determining the position of the interface between the two layers or determine the position of one layer relative to another layer based on the measured flow rate and/or pressure.

In accordance with another aspect of the present invention, it is proposed a method of controlling the depth location of the extraction tool material mining combine, which includes the setting of the depth location of the extraction tool material on signal positioning, obtained as described above.

In accordance with another aspect of the present invention, it is proposed a method of controlling the depth location of the extraction tool material mining combine, destined for the extraction of material in the upper layer, located on the lower layer having a permeability that is different from the permeability of the top layer, which consists of the following steps: placing at least one release fluid material, the fluid supply to the release, the measurement of the flow rate and/or pressure of the fluid, and determining which of the layers is the release of liquid, so that it was possible to establish the depth of the location of the extraction tool material relative to the two layers.

on Fig shows a perspective view from the front of the collector 7;

Figures 1 and 1A shows the exhaust manifold 10, with many editions of the liquid 12.1, 12.2., 12.3 and 12.4, which is shown schematically. Releases 12.1 and 12.2 go directly to the top gravel layer 14, and releases 12.3 and 12.4 appear in the lower clay layer 16 separated from the gravel surface of the partition 15. Collector editions forks from edinstvennoj the pipeline fluid 18, which supplies water to the releases. As is best shown in figa, particles of gravel are permeable so that water passing through the release 12.2, can pass through the gaps between the individual particles of gravel 14.1, as shown schematically by arrows 18. In contrast, clay 16 is relatively impermeable, so that it tends to clog the release 12.3 and block the flow of water, as shown by arrows 20.

The relative permeability of the gravel leads to the condition of maximum flow rate with low pressure, resulting in releases 12.1 and 12.2, while the relative impermeability of the clay 16 leads to a condition of relatively high pressure and low flow that occurs on releases 12.3 and 12.4. From this it follows that if the collector is entirely upwards in such a way that three or more releases will be coming out in the gravel 14, the conditions of low pressure and maximum flow will be dominant, while if the collector 10 is lowered to the position in which, for example, releases 12.2-12.4, go into the clay, the conditions of high pressure and low flow will be dominant. Thus, it becomes clear how due to the current condition monitoring of pressure and flow in a single pipe fluid 18 can control the position of the collector considers the flax gravel and clay, consequently, relative to the surface of the section 15.

Figure 2 schematically shows the extraction tool material in the form of a knife or bucket 22, forming part of an underwater mountain harvester, which makes cutting a passage 24 on the seabed. The knife 22 is shown at an optimum level when it is located directly under the surface of the partition 15 between the gravel 14 and the underside of clay 16. Due to the installation of the knife directly beneath this surface of section produce diamondiferous gravel, while at the same time in each iteration may take less clay. Exhaust manifolds 10 bolted to the side posts 26 and 28 on opposite sides of the knife 22 in the position in which they are in continuous contact with gravel and clay.

Figure 3 shows a device for determining the position 29 in accordance with the present invention. The pump 30 pumps the water through the supply line 18. The water passes through a 10 micron filter 32 and through the block of reducing the pressure of 34, in which the water pressure is reduced to a typical predetermined pressure and flow rate of 50 kPa and 140 l/sec respectively. After the water passes through the flow meter 36 and the pressure sensor 38, which allows you to accurately measure the water pressure or the pressure drop across it, using the pressure in the measuring pipe 39 from the power reduction is Alenia 34 as the reference pressure. Further, the pipe 18 of the liquid passes to the exhaust manifold 10.

As is best shown in figure 5, the exhaust manifold 10 has a casing 40 of solid steel, with many flanges 42 with holes that allow you to fasten them with bolts either side of the uprights 26 and 28 of the knife 22. Hard rubberized insert 44 is fixed on the side wall of the casing 40 and has a plurality of longitudinal protruding horizontal subcollection that releases 12.1-12.5, which have respectively 1, 2, 3, 4, and 5 individual nozzles 13 arranged horizontally. A series of five nozzles 13 in the bottom of the release 12.6 has the form of a rubber subcollector 48 mounted on the lower surface of the collector casing 40.

The signals from the flow meter 36 and the pressure sensor 38 is received on the schema processor 50 that is installed on the process vessel. The schema processor contains a conversion table, which includes the parameters of pressure and flow rate, corresponding to different levels of the collector casing relative to the surface section, ranging from the situation in which all releases occur in the clay, to a situation in which all releases occur in the gravel. Increasing the concentration of the nozzle 13 in the direction to lower subcollector leads to increased sensitivity in the area of the editions of 12.5 and 12.6, the level of which is relevant to the duty to regulate the desired level, which is shown schematically in figure 2, in which, for example, release 12.6 and possibly release 12.5 are in contact with outer soles of clay 16, and the other releases 12.1-12.4 face in the gravel 14.

The output signal from the schema processor 50 is supplied to the light indicator device 52, which is used for level indication of the location of the knife. Onboard operator 54 looking at the indicator and manually remotely adjusts the level of the knife by means of the actuator 56 of the knife 22 provided on the underwater mountain harvester. In an alternative embodiment of the present invention the output signal from the schema processor is used directly to control the actuator 56, thus to adjust the level of the knife, as shown schematically by the dashed line 58.

The indicator device 52, which is shown in more detail in figure 4, includes a light unit, which contains two Central green light source 60, intermediate the upper and lower orange light sources 62 and 64, and the upper and the lower red light sources 66 and 68. The surface of the partition 15 is shown as a line section 70 on the control card, and the upper and lower thresholds are shown using upper and lower lines 72 and 74, respectively. The position of the knife shown in graph 76, and may be before the foreseen auxiliary display device 78, where the indicator hold (HOLD) corresponds to the green light sources 60, the lights Down (DOWN) correspond to the orange and red light sources 62 and 66, and indicators "Up" (UP) correspond to the orange and red springs 64 and 68. This display gives clear instructions to the operator to move the blade up or down, depending on its position relative to the surface of the partition 70 and relative to the upper and lower thresholds 72 and 74.

Figure 6 shows the exhaust manifold 10, the laterally away from the knife 22 protruding from one of the two brackets 80, forming part of an underwater mountain harvester 82. Clearly shows that the base of the exhaust manifold 10 is located slightly below the front edge 22A of the knife, thereby exhaust manifold embedded in the sole of clay 16, while the knife works in the optimum position at the surface of the partition 15 between the upper gravel layer 14 and bottom layer of clay or the base 16.

7 and 8 shows the exhaust manifold 10.1, which has a steel casing with 40.1 having holes flange 42.1, which allows you to secure it with the bolts in the holes of the lateral columns 26 or 28 of the knife 22. The tilt release 12.6 attached to a steel casing 40.1 using cover 84, which is secured by bolts 86 to the steel casing 40.1. Release 12.6 has five nozzles 13. Water is supplied to the five nozzles 13 through vpusknogo the connection 88.

When the collector 10.1 is connected to the feeding pipeline similar to the one shown in figure 3, which is measured and controlled pressure and measured flow. Nozzle 13 is turned down to the clay or gravel. When the nozzle 13 is located in clay, then the measured pressure increases, and the measured flow rate is reduced. When the collector 10.1 is located in the gravel, then the measured pressure and the measured flow rate increases. Due to this, you can determine whether the nozzle 13 in clay or gravel. Therefore, the knife 22 can be omitted through the thickness of the gravel to clay, if continuously monitor the measured pressure and flow in the supply pipeline.

Although it is not shown in the drawings, can be used two collector 10.1 installed with a gap above each other, so that the nozzles of one of the collectors may be in the gravel, and the nozzle another collector can be in the clay, which allows to optimize the position of the knife 22.
