Description

  The present invention relates to a television monitor device for performing shelling operations such as abalone, sea urchin, turban shell, sea cucumber and the like and seaweed operations such as seaweed and mozuku living on the sea floor from the ship.

  Japanese Patent No. 5904567 (Patent Document 1), which the present inventor has already acquired about the “shellfish and algae collection system from the ship”, describes the image of the state of the collection and algae collected by the underwater television camera (C). Is displayed on the liquid crystal screen (39) of the monitor television (M) on the ship, and the operator holds the live image on the liquid crystal screen (39) while holding it with both hands. The working rod (P) is moved to collect shellfish and algae.

Japanese Patent No. 5904567

  However, in the configuration of the television monitor device described in Patent Document 1, even if there is an advantage that the installation height, the swinging angle, and the tilt angle of the monitor television (M) can be easily adjusted for the operator, the monitor television (M) The liquid crystal screen (39) is exposed and exposed to sunlight, so that it is dazzling visually and eyes are fatigued early, and the monitor TV (M) column ( 41) must be removed from the fixed stand (43), and the monitor TV (M) must be taken home with the column (41), which is inferior to the convenience of carrying.

  On the other hand, since the underwater TV camera (C) is attached to and integrated with the work rod (P) and moves together at all times, the more frequently the work rod (P) is moved, the faster the background image changes. Therefore, the collection target (A) cannot be collected quickly and reliably.

  In addition, the underwater television camera (C) only shoots the sampled object (actual) (A) as it is, regardless of the depth change to the seabed. Since it is not possible to shoot at a wide angle or zoom in for easy viewing from the ship, the collection workability and the collection result have not improved yet, and this becomes more prominent as the depth of the seabed increases.

  The present invention aims to improve such a problem, and in order to achieve the object, in claim 1, a live image of the state of shelling and algae collected by an underwater camera is displayed as a shellfish and algae operator. Is a television monitor device that displays on a monitor television for viewing on a work boat,

While accommodating installing the monitor television on the bottom of the waterproof bag, and the rigidity of the bottom receiving holder of that is fixedly supported on the peripheral portion of the work ship,

  The bottom part of the bag in which the monitor TV is stored and installed is inserted and fixed to the bottom receiving holder so that it can be inserted and removed freely from above,

  The anti-glare hood with a shape that widens as it goes from the viewing window with a smaller diameter than the opening of the bag toward the tip, and with the tip of the large caliber facing the monitor TV is inserted and removed from above into the bag. It is characterized in that it is set so that it can be inserted freely and the monitor TV can be seen through the viewing window of the inserted anti-glare hood.

  According to a second aspect of the present invention, the bottom receiving holder of the bag is formed into a U-shaped section having a depth substantially corresponding to the thickness of the monitor TV, and one blade plate in the flat torque hinge is attached and fixed to the U-shaped bag surrounding wall surface. ,

  By attaching and fixing the other vane plate in the flat torque hinge to the upper end of the pedestal that is detachably attached to the peripheral part of the work ship via the mounting base,

  The bottom receiving holder of the bag is defined so that the operator can adjust the inclination angle so that the monitor TV can be easily seen.

  In claim 3, the underwater camera is installed as an autofocus camera with an optical zoom function at the tip of a waterproof cylinder having a fixed length, and the middle of the waterproof cylinder is fixedly supported on the peripheral edge of the work ship.

  The remote control rod for changing the zoom magnification of the camera is derived from the root of the waterproof cylinder.

  According to the fourth aspect of the present invention, the bag is telescopic, and is urged and stretched to the maximum depth by a coil spring enclosed therein, and the depth can be adjusted by pressing and shrinking from the opening against the urging force. It is characterized by that.

  Further, according to a fifth aspect of the present invention, the antiglare hood is a box glasses type, and can be bent and flattened from a line that bisects both short sides of the observation window that opens in a rectangular shape.

  According to the above configuration of the first aspect, the bottom portion of the waterproof bag in which the monitor TV is stored and installed is inserted into and removed from the upper side to the rigid bottom receiving holder fixedly supported on the periphery of the work boat. While freely inserting and fixing, the antiglare hood with a shape that expands greatly as it goes from the viewing window with a smaller diameter than the opening of the bag to the front end, the state where the front end of the large diameter faces the monitor TV, Since the monitor TV is viewed through the viewing window of the anti-glare hood that can be inserted and removed freely from above into the bag, the video display screen of the monitor TV is dazzled by sunlight. There is no fear of shining, and there is an effect that it is possible to comfortably carry out shelling and algae extraction work from the ship while keeping the eyes safe for the operator.

  Moreover, when the shelling and algae collection work is finished, the bag in which the monitor TV is stored and installed is extracted from the bottom receiving holder fixedly supported on the peripheral edge of the work ship, and the bag is anti-glare. It is extremely convenient because it can be taken home with the monitor TV in a state where the hood is also stored.

  In that case, in particular, if the configuration of claim 2 is adopted, the bottom receiving holder of the bag has a U-shaped cross section having a depth substantially corresponding to the thickness of the monitor TV in the bag. The bottom receiving holder can be adjusted and maintained at a tilt angle that makes it easy for the operator to view the monitor TV by using a flat torque hinge, thus further improving the above effect.

  Further, if the configuration of claim 3 is adopted, the optical zoom function can be applied to the tip of the waterproof cylinder fixedly supported on the periphery of the work boat without being integrated with the underwater camera. It is built in as an autofocus camera with a built-in camera, so that the operator frequently moves the gripped work rod while looking at the monitor TV on the work boat to find and collect the target to be collected from the seabed. However, there is no risk that the captured images of the underwater camera (autofocus camera) will move rapidly together, and the fact that the zoom magnification can be changed (adjusted), it is possible to always see clear images. Yes, it helps to improve the collection results.

  If the structure of claim 4 is adopted, since the monitor TV is stored and installed at the bottom of the bag, adjusting the depth of the bag means adjusting the distance for viewing the monitor TV, and this can be done. In addition to improving the ease of viewing, the bag in which the monitor TV is housed can be pushed and shrunk from the opening and flattened to be carried conveniently.

  Furthermore, if the configuration of claim 5 is adopted, the box glasses-type anti-glare hood is folded and flattened, and can be taken back together with the monitor TV by being housed in the bag. Convenient.

  In that case, a gate-shaped metal frame column (29) is erected integrally from the middle of the camera mounting base (14) in the waterproof cylinder (13), thereby the remote control rod (25). The middle is supported with good stability. (30) and (31) are a pair of front and rear bearing bushes that are passed through the remote control rod (25) and fixed by pressing screws (32) and (33). One of the bearing bushes (30) (the front side in the illustrated example) is notched with a stopper pin receiving groove (34) having a constant opening (α) (for example, about 30 degrees) as shown in FIG. .

  Then, toward the center position of the stopper pin receiving concave groove (34), a stopper pin (35) for restricting the rotation angle is inserted and engaged from behind the metal frame column (29), thereby The remote control rod (25) is not excessively rotated in the left-right direction, and in the example shown in the figure, it is restricted to rotate only about 15 degrees in the left-right direction.

  In this respect, in the illustrated example, the stopper pin (35) is screwed into the stopper pin receiving concave groove (34) of the bearing bush (30) from behind the metal frame column (29). Pins that replace screws may be driven in and fixed. (36) is a rubber bush that takes charge of the remote control rod (25), and is fitted and integrated with the tail cover (20) of the waterproof cylinder (13). The waterproof cylinder (13) is filled with a waterproof material, a shock absorbing material, a drying material for preventing condensation, etc., but is not shown.

  A mounting base (S1) for fixing and supporting the underwater camera (autofocus camera) (C) to the work boat (B), and a mounting base for fixing and supporting the monitor television (M) to the work boat (B) ( S2) is a metal product (preferably a processed product from a stainless steel plate) having substantially the same configuration, and a pair of left and right vises (37a) that maintain a constant interval (W) as shown in FIGS. ) (37b), a horizontal coupling plate (38) inserted and fixed between the left and right sides, and a vertical bearing pipe (also fixed between the left and right sides of both vise (37a) and (37b)) 39), and is attached to and detached from the peripheral portion (Koveri) (41) of the work boat (B) by advancing and retracting the turning screw handle (40a) (40b) which becomes the vise (37a) (37b). It can be clamped and fixed freely.

  In this case, a pressing bolt (42) is screwed into the vertical bearing tube (39) so as to be able to advance and retreat, so that a pedestal of a waterproof cylinder supporting arm, which will be described later, can be pressed and fixed. (43a) and (43b) are cylindrical bearing nuts of the rotating screw handles (40a) and (40b), which are welded to the vise (37a) and (37b). Reference numerals (44a) and (44b) denote press washers that form the tip portions (front end portions) of the rotating screw handles (40a) and (40b).

  (45) is a support arm of the waterproof cylinder (13) incorporating the camera (C), which is composed of a metal tube bent in an L shape in plan view as shown in FIGS. A pedestal (46) that hangs down integrally from the base portion is inserted into the bearing tube (39) on the mounting base (S1) side so as to drop from above, and is fixed and maintained by the pressing bolt (42). It has become. It goes without saying that the pedestal (46) is also made of a metal tube and can be pulled out from the bearing tube (39).

  In the middle of the waterproof cylinder (13) having a fixed length (L), a relatively large clamp fitting (47) is fastened integrally by a plurality of bolts and nuts (48 in the example). In addition, a relatively small clamp fitting (49) is assembled in a substantially perpendicular relation between the waterproof cylinder (13) and the support arm (45) at the substantially central portion of the clamp fitting (47). Welded.

  For this reason, the small clamp fitting (49) that is pre-attached to the large clamp fitting (47) on the waterproof cylinder (13) side can be freely inserted and removed from the other end (tip) of the support arm (45). After being inserted, the clamp fitting (49) is fastened with a single bolt and nut (50), so that it can be kept in a fixed support state to the work boat (B).

  When the small clamp fitting (49) on the waterproof cylinder (13) side is inserted into the support arm (45), the waterproof cylinder (13) is swung around the horizontal axis of the support arm (45), and the inclination angle is set. Further, when the pedestal (46) of the support arm (45) is inserted into the bearing tube (39) on the mounting base (S1) side, the pedestal (46) is moved up and down to form a waterproof cylinder ( 13) Adjusting the installation height (immersion depth from the water surface in the underwater camera) or swinging the pedestal (46) about its own vertical axis, the installation direction of the waterproof cylinder (13) is adjusted. Can be adjusted.

  Next, the monitor TV (M) is provided with a video display screen (51) of a certain size (for example, 16 inches), and as shown in FIG. 11, the bottom (back) of the waterproof bag (E). In advance).

  The bag (E) has a moderate softness to fit to the monitor TV (M) and has a hardness, size, and planar shape so that the monitor TV (M) can be stably enclosed and carried in a fixed state. If necessary, it is stretched to a certain maximum depth (G) (preferably about 40 cm to about 65 cm) as shown in FIGS. 11 to 13 by the coil spring (52) encapsulated (for example, sewn) in itself. A telescopic type (bellows bellows) that is biased in a shape-retaining state and can be adjusted and maintained at an appropriate depth by pressing and shrinking the bag (E) from the opening (53) as shown in FIG. 14 against the spring biasing force. Formula) is preferred.

  The shape retention state of the maximum depth (G) in the bag (E) is that an operator visually observes the video display screen (51) of the monitor television (M) stored and installed at the bottom through the opening (53). This means securing an appropriate distance and preventing invasion of sunlight or rain until the image display screen (51) reaches the image display screen (51).

  Therefore, the depth adjustment of the bag (E) is useful for adjusting the distance at which the video display screen (51) is viewed, and the operator brings back the bag (E) in which the monitor TV (M) is stored. 14 is also useful for flattening as shown in FIG. 14 (ensuring a folded state that is adjusted and kept shallow to the thickness of the monitor TV). Moreover, it is preferable that the said bag (E) is black, dark brown, dark blue, and other dark colors on monitor TV (M) visual observation.

  (54) (55) is a pair of male and female fasteners (buckles) that maintain the contracted state of the bag (E), and the vertical positional relationship between the vicinity of the opening (53) and the vicinity of the bottom of the bag (E). It is installed. (56) is a pair of left and right handgrip handles, and (57) is a pair of front and rear suspension rings, on which a shoulder belt (not shown) is detachably locked.

  The monitor TV (M) in the state of being housed and installed at the bottom of the bag (E) is, as is apparent from FIG. 3, the flexible wiring cable (11) led out through the bag (E). The middle video cable (11b) is connected to the underwater camera (autofocus camera) (C) in the waterproof cylinder (13), and also via the power cable (11a) of the wiring cable (11). Thus, it is connected to the battery (10) mounted on the work boat (B), and the submarine target (A) taken by the camera (C) and the video of the sampling situation are displayed on the monitor TV (M ) On the video display screen (51) in real time.

  In this case, a power on / off switch (not shown) is installed on the monitor TV (M), and the monitor TV (M) and the camera (C) are turned on / off simultaneously by manual operation. Of course, the monitor TV (M) and the camera (C) are always connected to an energized state, and a pair of connection terminals (crocodile clips) (21) in the power cable (11a) is connected to a work ship. If it is detachably attached to the on-board battery (10) of (B), the power supply is automatically switched on, so that the shooting by the camera (C) and the display by the monitor TV (M) are quickly started up. It is desirable. In the illustrated embodiment, a 16-inch liquid crystal color television is adopted as the monitor television (M).

  (58) is a rigid bottom receiving holder for the bag (E), and substantially corresponds to the thickness (t) of the monitor TV (M) from a metal plate (preferably a stainless steel plate) as shown in FIGS. A bag enclosure that is shaped to have a substantially U-shaped cross section with a depth (d), and that the flat bottom surface (59) has a size and a planar shape that can receive the bottom surface of the bag (E), and stands up from there. The wall surface (60) surrounds the bottom of the bag (E) in a state where the monitor TV (M) is housed and installed so as not to be displaced or even fall off.

  In that case, in the illustrated embodiment, as clearly shown in FIG. 12, the bottom surface (59) of the holder (58) is a rectangle having a size substantially corresponding to the bottom surface of the bag (E), and a pair of front and rear short sides thereof. The bag enclosing wall (60) is bent continuously and integrally from the pair of left and right long sides, and the cable (11) can be conveniently wired and drained through the relief notches (61) at the four corners. However, the relief notch (61) may be omitted, and the bottom surface (59) of the holder (58) may be shaped into a polygon or an ellipse other than the rectangle.

  Further, (62) is a flat torque hinge for adjusting the video display screen (51) of the monitor television (M) to an inclination angle (θ) that is easy for the operator to see, and its pivot (stainless steel rod) (63 ) Through which the vane plate (64a) is connected to the bottom receiving holder (58) of the bottom receiving holder (58) having a substantially U-shaped cross section as shown in FIG. It is attached and fixed by welding or the like to the bag surrounding wall surface (60) standing up from the long side of (59).

  Similarly, the other vane plate (64b) in the flat torque hinge (62) is fixedly attached to the upper end of the bottom receiving holder pedestal (65) by welding or the like as shown in FIG. (66) is a torque value adjusting nut in the flat torque hinge (62), and the bottom receiving holder (58) of the bag (E) is fixedly held at the inclination angle (θ) adjusted thereby. As a result, the monitor television (M) in the bag (E) received by this is fixedly held at the inclination angle (θ).

  Here, the pedestal (65) for the bottom receiving holder of the bag (E) is made of the same metal tube as the pedestal (46) hanging from one end (root) of the support arm (45) in the waterproof cylinder (13). Thus, it is detachably attached to the peripheral part (collar) (41) of the work boat (B) via the monitor television (M) mounting base (S2).

  The mounting base (S2) for fixing and supporting the monitor TV (M) to the work boat (B) is as follows. The underwater camera (autofocus camera) (C) is fixed and supported to the work boat (B). Since it is the same as the mounting base (S1), the same reference numerals are only entered in the drawing, and a detailed description of the monitor TV mounting base (S2) is omitted, but the bag (E) The pedestal (65) for the bottom receiving holder is inserted into the vertical bearing tube (39) on the monitor TV mounting base (S2) side so as to drop from above, and may be pulled out from the bearing tube (39). Is possible.

  In that case, the installation height of the bottom receiving holder (58) and the installation height of the monitor television (M) in the bag (E) are set to the fixing bolt (42) for fixing the pedestal (65). Therefore, the vertical adjustment line can be set to an appropriate height that is easy for the operator to see, and when the pedestal (65) is inserted into the bearing tube (39) on the mounting base (S2), Can be rotated (swinged) by 360 degrees, and the video display screen (51) of the monitor TV (M) in the bag (E) is oriented in an appropriate direction that is easy for the operator to see. This state can be fixed by the pressing bolt (42).

  Furthermore, (67) is an anti-glare hood that is used by being detachably inserted into the bag (E) for viewing the video display screen (51) of the monitor television (M). It is shaped from a synthetic resin having a hardness into a so-called box-glass shape, and is given a black, dark brown, dark blue, or other dark color.

  That is, the anti-glare hood (67) is extracted from the rectangular viewing window (68) having a smaller diameter than the opening (53) of the bag (E) as shown in FIGS. It has a trapezoidal shape in plan view that gradually widens as it goes to the (lower end), and the tip (lower end) with a large aperture is directed to the monitor TV (M) and into the bag (E). It is designed to be inserted from above. By observing the video display screen (51) of the monitor TV (M) from the viewing window (68) of the anti-glare hood (67) having a smaller diameter than the opening (53) of the bag (E), Is preventing the invasion.

  In that case, the anti-glare hood (67) keeps the viewing window (68) in a rectangular opening shape, and the monitor TV (M) is observed from here, but after this is taken out from the bag (E), (Anti-glare hood) is folded flat from the bisector (YY) of both short sides of the viewing window (68) having a rectangular opening shape to the inside or outside, and stored in the bag (E). Can take home.

  The television monitor device for shellfish / algae work from the ship according to the illustrated embodiment of the present invention has the above-described configuration. As shown in FIGS. 1, 2 and 7 to 11, a small boat (for example, about 8 m to about 10 m in length and about 2 m to about 2.5 m in width) with a machine (not shown) is used as a work ship (B). The underwater camera mounting base (S1) and the monitor TV mounting base (S2) are placed in appropriate positions on the peripheral edge (collimation) (41) of the work boat (B).

  Further, it is desirable that the underwater camera (autofocus camera) (C) at the front end (lower end) in the waterproof cylinder (13) is immersed to a depth of at least (at least shallowly) about 10 cm from the water surface. When it is a place where it is difficult to see the target to be collected (A) on the seabed, the optical zoom magnification of the underwater camera (autofocus camera) (C) may be adjusted appropriately.

  Further, a waterproof tube (13) of the underwater camera (autofocus camera) (C), its supporting arm (45), a bag (E) in which a monitor TV (M) is preliminarily stored and installed, and its bag (E) To the tip of the work rod (P) prepared separately from the bottom receiving holder (58) of the fish, a collection tool in a form suitable for each collection target (A) such as sea urchin, abalone, sawfish, sea cucumber, seaweed, mozuku T) is fixed.

  Speaking of the working rod (P), this is made of a prepreg impregnated with a thermosetting resin such as a phenol resin or an epoxy resin in a FRP cloth such as a glass fiber cloth or preferably a carbon fiber cloth having high rigidity. The FRP composite prepreg is a FRP composite product that has been piped into several ply layers by heat curing, and has a fixed working length (for example, about 5 m) that reaches from the work ship (B) to the seafloor on the coast (磯). (About 10m), it is acceptable to use a single piece, but the same thickness of the main fence (P1), at least one intermediate hook (P2) and the leading edge (P3) as shown in FIG. By connecting and detaching from the tip attachment (P4) made of ABS resin or nylon, etc. of the tip (P3), the working length is reduced to the depth of the seabed. Depending on other conditions, it is preferred to use those which can be adjusted longer or shorter.

  In addition, in this case, as the tip attachment (P4) of the working rod (P), the sectional shape of the tip which becomes the mounting base (69) of the sampling tool (T) is, for example, a circle as shown in FIG. 18 or as shown in FIG. Several different shapes shaped like a D-shape, a triangle as shown in FIG. 20 (a), a quadrangle as shown in FIG. 20 (b), an ellipse as shown in FIG. 21 and the like are prepared. The tip of (P3) is interchangeably connected to the tip, and the attachment base (69) has a circular tip attachment (P4) having a sea urchin collection tool (T) as shown in FIG. A hook (71) serving as an abalone collecting tool (T) as shown in FIG. 19 is attached to the tip net (70), a tip attachment (P4) having a D-shaped cross section, and the cross section is triangular. Or square tip attachment P4) has an elastic gripping fork (72) to be used as a harvest tool (T) as shown in FIG. 20, and the tip attachment (P4) having an elliptical cross-section is a seaweed as shown in FIG. Macker (73), which is a kind of sampling tool (T), is set so that it can be securely clamped and fixed with a binding wire (74), etc., and the convenience of its installation and the strength of the mounting state are increased. It is desirable to plan.

  When the collecting tool (T) attached and fixed to the tip of the working rod (P) is assumed to be a sea urchin net (crawling net) (70) illustrated in FIG. The operator (fisherman) in a suitable position on the work boat (B) as shown in FIGS. 1 and 2 preferably sits down and sits on, and powers on. The work rod (P) held with both hands is inserted from the ship side toward the bottom of the sea, and the above net (70) at the tip (lower end) is moved to collect sea urchins that live on the sea floor. During the work process, the live video captured by the underwater camera (autofocus camera) (C) is displayed on the video display screen (51) of the monitor TV (M) stored and installed in the bag (E). Therefore, the operator (E) Through the anti-glare hood (67) inserted into the interior, while looking through the sight glass (68), find the sea urchins one after another and find the work rod (P) and the net (70) at its tip. Move skillfully with the technique and crawl without omission.

  In that case, since the work rod (P) is an FRP composite product having both durability and light weight, it is useful for its skillful operation. As the work rod (P), in particular, a configuration in which a plurality of kinds of main rods (P1), intermediate spear rods (P2) and leading rods (P3) having different unit lengths as described above are detachably coupled. If it is difficult to use during the insertion operation from the ship's bottom to the bottom of the sea, even if it is difficult to use, immediately add it from the hand side and lengthen it, or pull it out and shorten it. Such adjustment can be performed, which is extremely convenient.

  Then, when it can be visually confirmed from the video display screen (51) of the monitor television (M) that a certain amount (for example, about 20 to about 30) of sea urchin has entered the net (70), The work rod (P) may be lifted from the sea floor to the ship, the sea urchin may be taken into the work ship (B) from the net (70) at the tip, and stored in an appropriate container (not shown).

  In any case, the underwater camera (autofocus camera) (C) of the television monitor apparatus is not attached to and integrated with the work rod (P), and a waterproof cylinder (13) is provided separately from the work rod (P). Therefore, even if the operator frequently moves the gripping handle (P) while collecting the collection target object (A), the camera (B) is fixedly supported to the work boat (B). The photographed image of C) does not change rapidly.

  Moreover, the underwater camera (autofocus camera) (C) has an optical zoom function, and is built in and installed at the tip (lower end) of the waterproof cylinder (13) having a certain length. When the operator operates the remote control rod (25) led out through the waterproof cylinder (13) by swinging left and right from the ship, the optical zoom magnification is changed between the wide-angle state and the telephoto state. Therefore, regardless of the depth of the water up to the seabed, the captured image can always be clearly observed, and the collection target (A) can be collected efficiently in a short time. effective.

  On the other hand, the monitor TV (M) of the above TV monitor device is stored and installed in advance in the bottom of the waterproof bag (E), and the bottom of the bag (E) in that state is the periphery of the work boat (B). A bottom viewing holder (58) fixedly supported by the portion (collimator) (41) is inserted and fixed from above, and has a smaller viewing port (68) than the opening (53) of the bag (E). The anti-glare hood (67) is inserted into the bag (E) from above with the large-diameter leading end (lower end) directed to the monitor TV (M), and the inserted anti-glare hood (67 ) Through the viewing window (68), the video display screen (51) of the monitor television (M) is viewed. Dazzling Rather, you can work safely and comfortably collected.

  In that case, the bottom receiving holder (58) of the bag (E) has an inclination angle (θ) that is easily visible through the flat torque hinge (62) of the monitor TV (M) in the bag (E). Being able to adjust also helps to achieve the above effect.

  Further, since the bag (E) is urged to a shape-retaining state extended to the maximum depth by a coil spring (52) enclosed (sewn) in itself, the bag (E) itself is also anti-glare hood. When it is not in use, the monitor TV (M) can be stored and installed in a state of being compressed and flattened, and the anti-glare hood (67) can be folded and flattened to form a bag (E ) Can be stored inside.

  Then, when the sampling work on that day is finished, the connection terminal (crocodile clip) (21) of the power cable (11a) in the wiring cable (11) is removed from the battery (10) mounted on the work ship (B). Remove the clamp bracket (49) of the waterproof tube (13) containing the underwater camera (autofocus camera) (C) from the tip of its support arm (45), or monitor TV (M) Pull out the bottom of the built-in bag (E) upward from the bottom receiving holder (58), clean up the bag according to other needs and convenience on the following day, etc., then the bag (E) The anti-glare hood (67) is also housed and may be carried home with the waterproof cylinder (13).

  That is, the underwater camera mounting base (S1) with the pedestal (46) suspended from the support arm (45) of the waterproof cylinder (13) inserted and fixed, and the bottom receiving holder (58) of the bag (E) ) To the monitor TV mounting base (S2) with the pedestal (65) hanging down from the flat torque hinge (62) inserted and fixed to the work boat (B). It means that you can keep it.

  If there is no need or desire to repeat the sampling work after the next day, the underwater camera mounting base (S1) and monitor TV mounting base (S2) can be removed from the work boat (B) and brought home. good.
