The suction port 35 has such a size that suspended substances such as the sea bream staying in the surface layer can flow in together with water. A flange portion is provided on the periphery of the suction port 35 so as to extend in parallel with the base 31.

  At the center position in the axial direction of the suction member 34, a connecting portion 36 with the suction hose S1 is formed. The suction hose S1 is configured by a hose member such as a vinyl hose, for example. Then, in order to be able to guide the water and suspended substances flowing into the suction member 34 from the suction port 35 to the pump part 17b, one end is connected to the connecting part 36 of the suction member 34, and the other end is the pump. 17 is connected to the suction part of the pump part 17b. The suction hose S1 has a length and flexibility that do not hinder the movement of the second floating body 3 relative to the first floating body 2.

  The second float 41 for levitation of the second floating body 3 is a spherical hollow body made of plastic or a foamed plastic molded body, and has a through-hole penetrating the center thereof.

  The outer diameter of the second float 41 is set smaller than the outer diameter of the first float 21, and the sectional area of the second float 41 in the surface layer is smaller than the sectional area of the first float 21 in the surface layer in the floating state. When a suspended substance such as a sea urchin flows through the surface of the first floating body 2 toward the suction port 35 of the second floating body 3, the flow of the suspended substance is inhibited by the second float 41. Instead, the size is set so that it can flow smoothly toward the suction port 35.

  The second float 41 is fixed to the base 31 by making the second float 41 approach from above the support rod 43, inserting the tip of the support rod 43 into the through hole of the second float 41, and lowering the lower portion of the second float 41. This is performed by receiving the pad material 44 and supporting it at a predetermined height, screwing the nut into the tip screw portion of the support bar 43 protruding from the second float 41, and sandwiching the second float 41 from above and below.

  The buoyancy of the second float 41 allows the second floating body 3 to float by floating on the surface layer of a predetermined water area, and in that state, the suction port 35 can inhale suspended substances such as blue sea urchins staying on the surface layer with high efficiency. It is set to be arranged at a deep position, for example, a depth position that is about 2 cm lower than the water surface WL.

  As shown in FIG. 2, the second floating body 3 is accommodated in the first floating body 2, and the first float 21, the second float 41, and the suction port 35 are arranged in this order from the outside of the frame body 11 to the center in a plan view. Are arranged so that the second float 41 is interposed between the first float 21 and the suction port 35, and is connected to the first floating body 2 by a long floating body 51 which is a connecting means.

  The long floating body 51 is formed in a ring shape surrounding both the first float 21 and the second float 41 that are close to each other, and is provided so as to span between the first float 21 and the second float 41. It has been.

  The long floating body 51 is formed by connecting a plurality of floating elements 52 in series. The floating element 52 is formed of a hollow cylindrical body that can be easily bent, and a plurality of floating body holding ropes 53 are inserted into a through hole formed in the center portion so that the floating element 52 is connected in series. The long floating body 51 having a flexible structure that can be bent freely can be formed by connecting them together by winding a bonding material such as a vinyl adhesive tape around the portion.

  The floating body holding rope 53 of the long floating body 51 includes an annular body 24 attached to a preset height position of the first float 21 and an annular body 45 attached to a preset height position of the second float 41. Is inserted through each.

  The length of the long floating body 51 is a length that allows the second floating body 3 to move separately and independently within a preset range with respect to the first floating body 2, and the second floating body 3 is relative to the first floating body 2. Thus, the length is set to prevent excessive rotation and contact with the first floating body 2.

  Then, in a state where the first floating body 2 and the second floating body 3 are levitated, the surface layer region between the first float 21 and the second float 41 is partitioned from the outer surface layer region to be a closed region. It also has a function as a region forming means, and prevents suspended substances such as the sea cucumber from entering and staying in the surface layer region between the first float 21 and the second float 41.

  The long floating body 51 has a diameter of about 50 mm. The lower half 25 mm of the floating body 52 is submerged under the water surface WL, and the upper half 25 mm floats above the water surface WL. . In addition, suspended substances such as water flounder or the like floating in the surface water or in the surface layer are prevented from entering and staying in the surface layer region between the first float 21 and the second float 41.

  Since the second floating body 3 does not include a heavy object such as the pump 17 unlike the first floating body 2, the second floating body 3 is configured to be lighter than the first floating body 2. And it can move independently with respect to the 1st floating body 2, The moving direction can also move freely to a perpendicular direction, a horizontal direction, a tilting direction, etc. Therefore, for example, even when the first floating body 2 oscillates differently from the swaying motion of the water surface WL due to wave winds or the like, the second floating body 3 can move in synchronization with the swaying motion of the water surface WL, and the suction port 35 is suspended. It can always be arranged on the surface layer where turbid substances stay at a high concentration.

  The suspended matter removing apparatus 1 should remove suspended matter containing phytoplankton, for example, ako, as shown in FIG. 5 which shows an example of removing the ako from a predetermined water area preset in the castle moat A. It floats in the predetermined water area, is moved in the predetermined water area using a winch or the like, and the pump 17 is driven to suck the water stagnation in the surface layer from the suction port 35 together with water.

  The sea urchin sucked from the suction port 35 is guided to the pump part 17b of the pump 17 through the suction hose S1 (see FIG. 1), and is pumped together with water from the pump part 17b to the recovery device G on the shore through the discharge hose S2. It is separated from water by apparatus G. The water-separated water separated by the recovery device G is disposed, and the water separated by the recovery device G is returned to the moat A through the return pipe H after a predetermined treatment.

5, reference symbols B and C are shores, reference symbol D is a work yard, reference symbols D _{1 to} D ₃ are winches arranged in the work yard D, reference symbols E _{1 to} E ₃ are winches and suspended matter removal. A rope connecting the apparatus 1, symbols F _{1 to} F ₃ are pulleys, and symbols I ₁ and I ₂ are anti-pollution curtains.

  According to the suspended matter removing apparatus 1 having the above-described configuration, the suspended matter is placed at a high concentration in the suction port 35 of the second floating body 3 in a state where the suspended matter such as the sea cucumber is floated in a predetermined water area. The surface layer that stays, for example, at a depth of about 2 cm lower than the water surface WL, can be opened upward. Therefore, the suspended substance staying in the surface layer of the predetermined water area can be sucked and removed with high efficiency.

  In particular, the second floating body 3 provided with the suction port 35 is configured to be lighter than the first floating body 2 having the pump 17 and is separately and independently within a preset range with respect to the first floating body 2. Since it is connected with the 1st floating body 2 by the long floating body 51 so that it can move, even if it is a case where the 1st floating body 2 made the rocking motion different from the rocking motion of the water surface WL by a wave wind etc., the 2nd floating body 3 is the water surface. It can move in synchronism with the swaying movement of WL, and the suction port 35 of the second floating body 3 can always be arranged on the surface layer where suspended substances such as the sea bream stay at a high concentration. Therefore, the suspended matter can be efficiently sucked and removed without being affected by the wave wind.

  Further, according to the suspended substance removing device 1, the first floating body 2 and the second floating body 3 are floated by the second floating body 3 being accommodated in the first floating body 2 and connected to each other by the long floating body 51. The first float 21, the second float 41, and the suction port 35 are horizontally aligned in this order from the outside of the frame 11 toward the center, and the second float 41 is interposed between the first float 21 and the suction port 35. To be arranged.

  The second float 41 arranged at a position closer to the suction port 35 has a smaller outer diameter than the first float 21 arranged at a position separated from the suction port 35, and the surface layer has a lower outer diameter. The cross-sectional area is also set so that the second float 41 is smaller than the first float 21.

  Therefore, when a suspended substance such as a sea lion staying in the surface layer passes through the side of the first floating body 2 and flows toward the suction port 35 of the second floating body 3, the flow of the suspended substance is the second float. The suspended substance can be smoothly flowed toward the suction port 35 without being hindered by 41, and the suction efficiency of the suspended substance can be improved.

  In addition, a long floating body 51 is bridged between the first float 21 and the second float 41 that are located in the vicinity of each other, and the first float 21 and the second float 51 are floated on the water surface WL. The surface layer region between the two floats 41 is defined as a blockage region partitioned from the outer surface layer region, and suspended substances such as blue sea bream enter the surface layer region between the first float 21 and the second float 41 and stay there. It is configured to prevent this.

  Therefore, when the suspended solid flows through the side of the first floating body 2 and flows toward the suction port 35 of the second floating body 3, the suspended matter is sucked into the suction port without hindering the flow of the suspended material. It is possible to flow smoothly toward 35, and the inhalation efficiency of the suspended substance can be improved.

  Then, since the outer surface of the floating element 52 has a smooth cylindrical shape, the suspended matter that has flowed to the long floating body 51 is slid on the smooth outer surface toward the suction port 35 of the second floating body 3. In addition, when the floating element 52 comes into contact with the first float 21 or the second float 41, the first floating body 2 and the second floating element 52 can be moved by sliding on the smooth outer surface of the floating element 52. 2 The independent and independent relative movement of the floating body 3 can be performed smoothly.

  In addition, this invention is not limited to the above-mentioned embodiment, A various change is possible in the range which does not change the meaning of this invention.

  For example, in the above-described embodiment, the configuration in which the long floating body 51 is bridged between the first float 21 and the second float 41 approaching each other as the closed region forming means has been described as an example. In place of the first float 21 and the second float 41 approaching each other, a rectifying plate is bridged, and the first float 21 and the second float 41 are sandwiched from the left and right sides at the surface layer position. The surface layer region between the second float 41 and the outer surface layer region is defined as a closed region, and the suspended substance enters and stays in the surface layer region between the first float 21 and the second float 41. It is good also as a structure which prevents. And instead of the long floating body 51 as the connecting means, a chain connecting the first float 21 and the second float 41, for example, a chain floating on the water surface WL used for dividing the pool into a plurality of lanes. It is good also as a structure which provides what coat | covered the shape thing with vinyl, and can move the 2nd floating body 3 separately with respect to the 1st floating body 2 within the preset range.
