  Further, the wiring relay box receiving arm (71) is formed of a round bar having a fixed length (W) as shown in FIG. 29, and a pair of left and right parallel lifts that are integrally suspended from the front end side (one end side). The guide groove (82) is adapted to receive the elevation ridge (60) on the wiring relay box (B) side.

  In that case, even if the wiring relay box (B) is in the reverse direction (reversed state) between the front chamber (F) and the rear chamber (R), the pair of right and left raised / lower ridges (60) are connected to the wiring relay box receiving arm. Similarly, it can be inserted into the lifting guide recess (82) on the (71) side without hindrance. Therefore, contrary to the illustrated embodiment, the depth of the front chamber (F) may be formed deeper than the depth of the rear chamber (R).

  Further, the base end side (the other end side) of the wiring relay box receiving arm (71) is held by an angular (regular polygon) clamp fitting (83). (84) is a plurality of screw fasteners for fastening and fixing the clamp fitting (83), and (85) is a pedestal that projects integrally from the lower end of the clamp fitting (83), and the center of the pedestal (85) An insertion leg pipe (86) that hangs down integrally from the section is inserted into the bearing pipe (80) on the swivel strut (70) side so as to be freely inserted and removed from above.

  At that time, the wiring relay box receiving arm (71) is moved up and down to adjust its installation height, and the receiving arm (71) is similarly rotated around the vertical axis (Y2-Y2) on the base end side at a desired angle. It can be positioned and set so that it is easy to see the monitor TV (M) for shelling and algae collection work by turning it only and changing the direction and position of the tip side. The positioning and fixing of the turning angle and the installation height is achieved by screwing the holding bolt (81) on the turning column (70) side and holding the insertion leg pipe (86) of the pedestal (85) in the clamp fitting (83). Just add it.

  Moreover, the wiring relay box receiving arm (71) has a desired angle (β) around a horizontal axis (XX) of a round bar extending by a certain length (W) as shown by a chain line in FIG. (Γ) can be tilted back and forth, and the wiring relay box (B) received and held by this and the monitor TV (M) can be adjusted and set to a posture that is easy to see in shelling and algae collection work. It can be done.

  The positioning and fixing of the inclination angle (β) (γ) is performed by tightening the screw fastener (84) of the clamp fitting (83) squared in the regular polygon and rotating the round bar held by the clamp. It can be achieved by not allowing.

  (87) is an inclination limit regulating stopper integrally projected from the base end side of the wiring relay box receiving arm (71) through a long hole (88) cut out as a vertically long shape in the clamp fitting (83). It is a pair of front and rear, and consists of bolts implanted in the round bar. The limit of the inclination angle (β) (γ) to be defined by the stopper (87) being locked to the opening edge of the long hole (88) is about 30 degrees in the front-rear direction. It is preferable to keep it from falling down below this.

  The tilting operation of the wiring relay box (B) received by the receiving arm (71) may be tilted forward or backward while holding the wiring relay box (B) with one hand. As an operation lever that extends the specified stopper (87) for a long time, it can be tilted forward or backward while holding it with one hand.

  The shell-fishing / algae-working system according to the present invention has the above-described configuration. In use, the underwater television camera (C), the camera (C), and the first electric wiring cable (11) are provided. And a second electric wiring cable (12) scheduled to be connected from the monitor television (M) to the battery (10) mounted on the work boat (A). Carrying the wiring relay box (B) stored together (collectively) as shown in FIGS. 20 to 22 and a support stand (S) for attaching the wiring relay box (B) to the work boat (A) Then, bring it to the work boat (A) that is parked on the shore.

  As the work boat (A), a small boat with an outboard motor (not shown) (for example, a length of about 8 m to about 10 m, a width of about 2 m to about 2.5 m) is usually used, and its periphery As shown in FIGS. 15 to 17 and FIGS. 1, 2, and 31, the mounting frame base (69) of the support stand (S) is stabilized by the vise (72a) (72b). Put it in the bag and fix it.

  14 to 19, the insertion leg pipe (79) on the swivel strut (70) side is inserted into the bearing pipe (73) on the installation frame base (69) side from above, and the swivel strut (70 The insertion leg pipe (86) on the wiring relay box receiving arm (71) side is further inserted into the bearing pipe (80) side on the) side from above.

  In that case, the swivel support (70) is raised and lowered, it is turned by a desired angle around the vertical axis (Y1-Y1), and the wiring relay box receiving arm (71) is raised and lowered. Around the vertical axis (Y2-Y2) by a desired angle, and the installation height and position of the wiring relay box (B) received and held by the receiving arm (71) (from the operator in the ship) Whether the distance is close or far) and the directionality (whether or not it is in front of the worker) are adjusted and set so that it is easy for one worker (fisherman) to collect shellfish and algae from the ship. Needless to say, the adjustment state of the turning angle is fixed by the corresponding presser bolt (75) (81).

  In addition, the wiring relay box receiving arm (71) is inclined around the horizontal axis (XX) of the round bar forward or backward by a desired angle (β) (γ) to the receiving arm (71). The wiring relay box (B) to be received and held and the monitor TV (M) are adjusted and set in a posture that is easy for the operator (fisherman) to see and observe during shelling and algae collection.

  In this regard, FIGS. 31 and 32 show a use state in which the wiring relay box (B) is inclined backward by about 30 degrees. Both the adjustment state of the angle (γ) inclined backward and the adjustment state of the angle (β) inclined forward are fixed and maintained by the screw fastener (84) of the clamp fitting (83).

  When various adjustments of the support stand (S) are completed due to the relationship with the work boat (A), the wiring relay box (B) is moved to the lifting guide recess (82) on the wiring relay box receiving arm (71) side. The up-and-down ridge (60) on the side is inserted and loaded so as to drop from above as shown in FIGS. However, it is of course possible to perform various adjustment operations of the support stand (S) after the insertion and loading, and the order thereof does not matter.

  In any case, if the wiring relay box (B) is attached and fixed via the support stand (S) to a position where it is easy for the worker to collect the shell and algae on the work boat (A), the shell is collected.・ Because preparations for starting the algae work are completed, the underwater television camera (C) at the tip of the first electric wiring cable (11) pulled out from the rear chamber (R) of the relay box (B) Is attached and fixed in the middle of the collection basket (P) as shown in FIGS.

  For the attachment, one of the eyeglass-type clamp fittings (37a) and (37b) in the folded state of the underwater television camera (C) as shown in FIG. 24 is extended and deployed as shown in FIGS. What is necessary is just to fix to a collection hook (P) by fastening of a screw fastener (38). In addition, the first electric wiring cable (11) of the underwater television camera (C) is bundled along the sampling rod (P), so that the manipulation operation of the sampling rod (P) described later can be performed. It is desirable to prevent the electric wiring cable (11) from swinging unnecessarily.

  In that case, the mounting position of the underwater television camera (C) is set so that the tip (collection tool) of the collection rod (P) is within the range of the viewing angle (view angle) (θ) of the camera lens (26). decide. By moving and adjusting the mounting position along the longitudinal direction of the sampling rod (P), only the sampling target (O) is greatly zoomed in, or a wide range of images can be taken up to the periphery of the target (O). It may be determined as follows.

  On the other hand, the second electric wiring cable (12) is pulled out from the lower side of the front chamber (F) in the wiring relay box (B) and connected to the onboard battery (10) of the work boat (A) as shown in FIG. At the same time, the video display screen (39) of the monitor television (M) housed in the upper side of the front chamber (F) is kept open so that it can be viewed and observed.

  As the collection tool (T), a shape suitable for the collection target (O) is attached and used at the tip of the collection basket (P). This is the sea urchin net illustrated in FIG. The sea urchin collection work will be described in detail as (Ugly Net) (20). One worker (fisherman) can easily work on the work boat (A) as shown in FIGS. In addition to turning on the power on / off switch (41) of the above monitor TV (M), the operator also puts the sampling rod (P) gripped with both hands from the ship onto the seabed. The sea urchin (20) at the tip is moved to collect sea urchins that live on the seabed. During the process, the live video captured by the underwater TV camera (C) Monitor TV (M This is displayed on the video display screen (39), so that the operator can find the sea urchins one after another while observing and observing them, and manually use the sampling trough (P) and the net (20) at its tip. Move it skillfully and crawl without omission. At that time, the harvesting basket (P) is an FRP composite product having both durability and light weight, and is thus useful for its skillful operation.

  In addition, as the harvesting rod (P), a configuration in which the above-mentioned several types of the main rod (P1), the intermediate rod (P2), and the leading rod (P3) having different unit lengths are detachably coupled together. If it is adopted, even if it does not correspond to the depth of the water and it is difficult to use when inserting from the ship to the seabed, it will be added from the hand side immediately and lengthened, or conversely pulled out and shortened. This is extremely convenient.

  When the above-mentioned net (20) can be visually confirmed and confirmed from the video display screen (39) of the monitor television (M) that a certain amount (for example, about 20 to about 30) of sea urchin has entered, The above-mentioned collection rod (P) is pulled up from the sea floor to the ship, and the sea urchin is taken into the work ship (A) from the net (20) at the tip, and stored in an appropriate container (not shown). In the lifting process, as shown in FIG. 34, the base of the sampling rod (P) is brought into contact with the peripheral portion (Koveri) of the work boat (A), and the contact portion is used as a rotation fulcrum. (P) is turned up as indicated by arrows (Z1) and (Z2), and at the same time, it is drawn to work ship (A) so that it slides as shown by other arrows (E1) and (E2), or it is turned upside down once. After becoming the posture, the peripheral edge of the work boat (A) ( It is only necessary to bring the collection rod (P) into the work boat (A) and pull it up as if it were slid while it is placed on the beli), so that a series of lifting operations can be performed quickly and easily. be able to. The fact that the collecting basket (P) receives buoyancy as an FRP composite product also contributes to the ease and smoothness of the lifting operation.

  As the sea urchin collection work, about 20 to about 30 units are used as unit quantities, and by repeating the insertion (down) operation and the reverse (up) operation to the bottom of the collection tub (P), A large amount of the target to be collected (O) can be efficiently collected under a comfortable working posture on the ship.

  Further, the abalone and the trumpet are collected as the abalone hook (21) illustrated in FIG. 7 and the gripping fork (22) illustrated in FIGS. 8 (a) and 8 (b). In this work, the worker (fisherman) is still abalone inhabiting the seabed while watching and observing the live video of the underwater TV camera (C) displayed on the monitor TV (M) on the ship. It is possible to search for the tuna and the trumpet one after another, and skillfully operate the collecting rod (P) and the hook (21) and the gripping fork (22) at the tip thereof from the ship, thereby efficiently collecting them. However, the abalone and turban shell collection work differs from that of the sea urchin, and it is necessary to pull the collection rod (P) from the seabed and take it into the work boat (A) each time it is collected. .

  In any case, the underwater television camera (C) is attached and fixed in the middle of the collecting rod (P), and the collecting rod (P) is placed at the center of the video display screen (39) on the monitor television (M) on the ship. ) Is positioned and fixed as shown in FIG. 12, and only the background image changes depending on the movement of the sampling rod (P) and the underwater television camera (C). Therefore, it is easy to find the collection target (O) one after another, and there is an advantage that anyone can reliably collect the target (O) so that the collection tool (T) is hit one by one.

  In particular, when the sampling tool (T) is exchanged in accordance with the sampling target (O), the mode change switch (40) of the monitor television (M) is operated to display on the video display screen (39). The direction of the image is changed 90 degrees around the center of the tip (collection tool) of the collection rod (P), and is positioned on the upper, lower, left or right side of the collection tool (T). If set, the search for the eye-collecting target (O) and the accuracy of its collection can be further improved, which is extremely beneficial.

  In any of the above-mentioned various collection operations, when the work on that day is finished, the underwater television camera (C) is removed from the collection basket (P) and together with the first electric wiring cable (11) It is stored in the rear chamber (R) of the wiring relay box (B).

  At this time, in a posture state in which the wiring relay box (B) is inclined forward by a desired angle (preferably about 30 degrees) (β) as shown in FIG. 33, the camera receiving rod (66) in the rear chamber (R) is provided. ) And the underwater television camera (C) are housed, and the long first electric wiring cable (11) is neatly wound around the camera receiving rod (66) as a winding core.
