Description

  The present invention relates to an apparatus for exploring the state of a submarine formation such as a sea or a lake using sound waves, that is, using a sound wave transmission type geological exploration device.

  As for the conventional geological exploration in the water area, there is no need to give a specific example, and a method of directly towing a sound wave transmission type geological exploration device by a ship, or traveling and exploring with a pole fixed on the side of the ship is adopted.

  In any of the conventional methods, a large amount of bubbles are generated from the bow to the bottom of the ship due to the traveling of the ship, and this scatters sound waves.

  In addition, the method of towing a geological explorer is difficult to explore in shallow water because of the danger of hitting the probe to the bottom of the water. On the other hand, the anchorage method on the shore side could not be used for small ships because the balance of the ship was lost.

  From the above, the conventional exploration method could not conduct exploration in waters shallower than 3 m, and hindered exploration in tidal flats, rivers and lakes with many shallow waters.

  A geological exploration device that uses a ship to move a sound wave-type geological exploration device to explore the bottom of the sea, such as the sea. It is made of a material that can transmit sound waves to a ship that can move even in water below 3m, A storage room having a bottom wall that constitutes a part of the ship bottom is provided, and the sound wave transmitter / receiver of the sound wave generation type geological exploration device is placed on the bottom wall immersed in water and stored in the storage room. In addition, the basic means is that a water drainage frame is provided on the bottom of the ship that prevents the rising of the bow of the moving boat and the inflow of water bubbles directly below the bottom wall, and the water drainage frame has the highest width. Provided with a pair of concave plate bodies with a concave outer surface, with the depth of recess gradually decreasing from the front edge to the rear edge direction and the height width gradually narrowing. In the plan view, the bottom wall is located on the inside. It prevents the flow of blister into the raised and the bottom wall position of the neck, to perform without hindrance the formation exploration.

  FIG. 1 shows an embodiment of a geological exploration device according to the present invention, FIG. 1 is a schematic front view showing the arrangement relationship of each part, FIG. 2 is a bottom view, FIG. 3 is an enlarged sectional view of FIG. FIG.

  FIG. 1 is a boat (ship) 1 constituting the main body of the geological exploration device according to the present invention. The boat 1 is constituted by an aluminum flat bottom boat so as to use light weight and shallow draft. In addition, it is convenient for handling and can move (run) freely even in shallow water below 3m, and the movement is performed by the outboard motor m.

  Further, the boat 1 has a draining frame 2 protruding from the bottom of the boat so that water bubbles generated during movement (running) do not flow inside the draining frame 2.

  The draining frame 2 includes a substantially V-shaped draining part 2A in plan view, and left and right guide part pieces 2B extending in parallel with the rear ends of the component pieces 2A 'of the draining part 2A. The tip of the draining part 2A is arranged on the bow side of the boat, and it is arranged in a divergent shape and symmetrically, and the presence of this draining frame 2 prevents the bow of the moving boat from rising and bubbles generated during the movement As a result, the geological exploration operation is performed reliably and accurately.

  The left and right component pieces 2A ′ constituting the drainer 2A of the drainer frame 2 have the highest height and are recessed in the direction of the guide piece 2B from the end edge 2 ′ having a curved recess. It is composed of a concave plate body having an outer surface concave shape whose depth is gradually reduced, and this is made to be continuous with a guide portion piece 2B having a flat outer surface shape.

  Further, the boat 1 is provided with a storage chamber 3, and the acoustic wave transmitter / receiver 4 a of the sound wave transmission type geological exploration device 4 is stored in the storage chamber 3.

  The storage chamber 3 is composed of an FRP box body having an upper surface opening, and a window 5 provided between the left and right guide pieces 2B on the bottom of the boat 1 is closed by a part of the bottom wall 3a of the storage chamber 3. A part of the bottom of the ship is configured, and the part of the bottom wall 3a that closes the window 5 is in direct contact with water outside the ship.

  As described above, the sound wave transmission type geological exploration device 4 is arranged so that the sound wave transmitter / receiver 4a constituting the spacecraft is always located directly above the window 5 so that sound waves are transmitted / received through the window 5. In order to prevent gas (air) from interposing between the wave receiver 4a and the bottom wall 3a of the receiving chamber by immersing at least the acoustic wave receiving / receiving unit 4a in the water injected into the receiving chamber 3 It is.

  Therefore, when a sound wave transmission / reception operation is performed in the sound wave transmission / reception unit while traveling in a required water area such as the sea or lake, the sound wave is transmitted / received through a part of the storage room bottom wall 3a (5 parts of the window) and the geological exploration is performed. During this exploration survey, that is, during traveling of the boat 1, water bubbles (air) generated during traveling due to the presence of the draining frame 2 protruding from the bottom of the boat are directly below the window 5, that is, directly below the sonic transducer 4a. In addition, the cross-sectional curved shape of the draining portion 2A constituting the draining frame 2 prevents the bow from being lifted, and the sound wave transmission / reception operation is performed smoothly.

  The material of the bottom wall 3a of the storage chamber 3 is FRP because it transmits sound waves and fulfills its function as the bottom wall material of the water container. Any material other than FRP can be used as long as this condition is satisfied. Of course, there is no inconvenience even if this material is used.
