  The mooring device 10 is a device for mooring such floating bodies such as the ship S, and is a fixed wire rope that is a first stretched body stretched between the first inclined surface 2a and the second inclined surface 2b. 11. A mooring line holding part moving mechanism 12 is provided which is connected to the fixed wire rope 11 and to which a reel device 16 as a mooring line holding part is fixed.

  The fixed wire rope 11 is formed by twisting a plurality of steel strands around an axis. This fixed wire rope 11 passes through the upper part of the second mooring position 5 of the ship S corresponding to the substantially central water area of the reservoir 1, and is installed on the first inclined surface 2a and the second inclined surface 2b. 2d, and tension is held and stretched in a region of the second mooring position 5 between the fixed portions 2c and 2d in a state where a pulley device 13 described later is suspended. . In the present embodiment, the fixing portions 2c and 2d are formed by concrete blocks embedded in the first inclined surface 2a and the second inclined surface 2b.

  The mooring line holding unit moving mechanism 12 includes a pulley device 13 that is a rotating body, a winder 14 that is a winding and unwinding unit, a moving wire rope 15 that is a second stretcher, a reel device 16 that is a mooring line holding unit, The pulley device 13 is fixed at a position corresponding to the second mooring position 5 in the fixed wire rope 11 formed with the U bolt 17 and extending over the second mooring position 5 of the reservoir 1. In the present embodiment, in the vicinity of the fixed portion 2c installed on the first inclined surface 2a, the hoisting machine 14 is installed sharing the concrete block and the foundation portion of the fixed portion 2c. A moving wire rope 15 is installed between the winder 14 and the pulley device 13, and a reel device 16 is fixed to a predetermined portion via a U bolt 17. A mooring line 16a for mooring a floating body such as the ship S is wound and accommodated in the reel device 16.

  The hoisting machine 14 includes a first drum 14a, a second drum 14b, and an operation switching unit 14c, and is integrally formed. A proximal end of the moving wire rope 15 is connected to the first drum 14a, and the moving wire rope 15 is a pulley. It winds around the apparatus 13 and is folded back, and its tip is further connected to the second drum 14b. By the operation of the operation switching unit 14c, the base end side of the moving wire rope 15 is sent in the forward direction close to the first inclined surface 2a by the first drum 14a, and by the second drum 14b by the switching operation of the operation switching unit 14c. The proximal end side of the moving wire rope 15 is sent in the reverse direction away from the first inclined surface 2a. The hoisting machine 14 is preferably a pneumatic or hydraulic one that can be operated in a mountainous reservoir 1 that is not equipped with power distribution equipment.

A reel device 16 is fixed by a U bolt 17 at a predetermined position of the moving wire rope 15 connected to the winder 14. A reel unit (not shown) is accommodated in the reel device 16, and a mooring line 16a is wound around the reel unit and accommodated. The reel portion is biased by a spring (not shown) in a direction in which the mooring line 16a is wound around the reel device. Further, a hook 16b is attached to the tip of the mooring line 16a and is locked to a locking portion (not shown) formed at the tip of the ship S.

  Next, the mooring procedure of the ship S using the mooring device 10 according to the present embodiment will be described.

  2 (a) and 2 (b) show a state where the ship S is moored at the first mooring position 4 corresponding to the water area near the first inclined surface 2 a using the mooring device 10, and substantially in the center of the reservoir 1. It is a figure explaining the state made to moor at the 2nd mooring position 5 applicable to a water area.

As shown in FIG. 2A, the mooring line 16a is pulled out from the reel device 16 fixed to the moving wire rope 15 via the U-bolt 17, and the hook 16b attached to the tip of the mooring line 16a is inclined first. It is made to latch on the latching | locking part of the ship S anchored in the water area near the surface 2a. In this state, the ship S is moored at the first mooring position 4.

Then, as shown in FIG. 2B, the hoist 14 is moved away from the first mooring position 4 while the ship S is engaged with the hook 16b of the mooring line 16a, and the second mooring position. 5 is driven in the forward direction, the base end side of the moving wire rope 15 is fed in the direction approaching the first inclined surface 2a following the driving, so that the reel device 16 fixed to the moving wire rope 15 is provided. The ship S connected via is moved in the direction of the second mooring position 5 indicated by the arrow B. In this state, the ship S is moored at the second mooring position 5.

  FIG. 3 is a diagram illustrating the state of the mooring device 10 when the water level of the reservoir 1 fluctuates. As shown in the figure, the water surface L2 is a water surface in a situation where the water level of the reservoir 1 is lowered by the fluctuation width h due to discharge of the dam or the like. Due to the drop in the water level of the reservoir 1, the mooring line 16 a wound and accommodated in the reel device 16 due to the weight of the ship S connected to the mooring line 16 a resists the biasing force of the spring that biases the reel device 16 in the winding direction. Then, the fluctuation range h of the water level is drawn, and the ship S descends following the decrease in the water level. At this time, since the sum of the urging force of the spring that urges the reel device 16 in the winding direction and the buoyancy acting on the ship S is equal to the weight of the ship S, the mooring line 16 is kept in tension and the ship S Is held at the second mooring position 5.

  On the other hand, as the water level of the reservoir 1 rises, the mooring line 16a is wound up following the urging force of the spring urging in the reel device 16 by the buoyancy acting on the ship S, and the water level rises. Then, the ship S rises. At this time, since the sum of the urging force of the spring urging in the winding direction in the reel device 16 and the buoyancy acting on the ship S is equal to the weight of the ship S, the mooring line 16a is maintained in a tension state and the ship S Is held at the second mooring position 5.

  When the ship S moored at the second mooring position 5 is used, the ship S is moved from the second mooring position 5 to the first mooring position 4 and brought into contact with the first inclined surface 2a. That is, when the hoisting machine 14 is driven in the reverse direction to move the ship S away from the second mooring position 5 and close to the first mooring position 4 by operating the operation switching unit 14a of the hoisting machine 14, this driving is performed. Accordingly, the reel device 16 fixed to the moving wire rope 15 is moved in the direction of the first mooring position 4 indicated by an arrow C. Moved. In this state, the ship S is moored at the first mooring position 4.

  By setting it as the above structures, the fixed wire rope 11 which comprises the mooring apparatus 10, the pulley apparatus 13 fixed to the fixed wire rope 11, and the corresponding position of the 1st inclined surface 2a facing this pulley apparatus 13 are set. An installed winder 14, a moving wire rope 15 wound between the winder 14 and the pulley device 13, a reel device 16 fixed to the moving wire rope 15 and winding and accommodating a mooring line 16a; Since the mooring line connecting device 12 configured as a land facility and airspace facility is formed and not submerged in the reservoir 1, early corrosion progress due to the facility always in contact with water The ship S can be moored after the improvement of the durability of the mooring device 10 is obtained by preventing the deterioration of the equipment due to the above. In addition, the mooring device 10 is formed by land facilities and airspace facilities and is not submerged in the water area, so driftwood and other drifting objects drifting in the water area are entangled in the underwater facilities and the water surface facilities such as the mooring line 16a. There is no risk of cutting the mooring line 16a, and the possibility of failure is greatly reduced. Moreover, since it can obtain durability and can be formed with a simple configuration, the equipment cost can be reduced.

  When the water level of the reservoir 1 does not fluctuate or is moored only for a short time, the hook 17 attached to the mooring line 16a wound and accommodated in the reel device 16 at the first mooring position 4 is used as the engaging portion of the ship S. It is possible to moor simply by locking. On the other hand, when the water level of the reservoir 1 fluctuates significantly due to flooding or the like, the ship S is moored at the second mooring position 5 by the moving wire rope 15 so that the water level is not maintained due to the lowering of the water level. It is possible to avoid the ship S from being stranded on the one inclined surface 2a.

  Further, the reel device 16 for mooring the ship S via the mooring line 16a is urged by a spring in a direction in which the mooring line 16a is wound into the reel device 16, and the mooring line 16a connected to the ship S is always moved. Since it is held in a tension state, it is securely held at the second mooring position 5 without overturning the ship S even if the water level fluctuates significantly due to rainfall or the like. Further, since the reel portion around which the mooring line 16a is wound is urged by the spring in the direction of winding in the reel device 16, the ship S is temporarily out of the region of the second mooring position 5 due to strong winds and waves of strong winds. The mooring line 16a is again moored and held at the second mooring position 5 by the biasing force in the direction of winding the mooring line 16a around the reel device 16.

The hoisting machine 24 is installed in common with the concrete block and the base portion of the fixed portion 2c. A moving wire rope 25 is installed between the hoist 24 and the pulley device 23, and a reel device 26 is fixed to a predetermined position via a U bolt 27. In the reel device 26, a mooring line 26a for mooring a floating body such as the ship S2 is wound and accommodated.

  The winder 24 includes a first drum 24a, a second drum 24b, and an operation switching unit 24c, and is integrally formed. A proximal end of the moving wire rope 25 is connected to the first drum 24a, and the moving wire rope 25 is a pulley. It is wound around the device 23 and folded back, and the tip is further connected to the second drum 24b. By the operation of the operation switching unit 24c, the proximal end side of the moving wire rope 25 is sent in the forward direction close to the second inclined surface 2b by the first drum 24a, and by the second drum 24b by the switching operation of the operation switching unit 24c. The proximal end side of the moving wire rope 25 is sent in the reverse direction away from the second inclined surface 2b.

  The pulley device 23 of the second mooring rope holding part moving mechanism 22 is the pulley apparatus 13 of the first mooring rope holding part moving mechanism 12, the moving wire rope 25 is the moving wire rope 15, the reel device 26 is the reel device 16, and the U bolt. 27 corresponds to each of the U bolts 17 and will not be described in detail except for the points described above.

  Next, mooring procedures for the ship S1 and the ship S2 using the mooring device 30 according to the present embodiment will be described. First, the mooring line 16a is pulled out from the reel device 16 fixed to the moving wire rope 15 of the first mooring line holding part moving mechanism 12 via the U bolt 17, and the hook 16b attached to the tip of the mooring line 16a is attached to the first hook 16b. Engage with the locking portion of the ship S1 anchored in the water area near the inclined surface 2a. In this state, the ship S1 is moored at the first mooring position 4.

  Then, when the ship S1 is engaged with the hook 16b of the mooring line 16a, the winder 14 is driven in the forward direction to move the ship S1 away from the first mooring position 4 and close to the second mooring position 5. Following this drive, the proximal end side of the moving wire rope 15 is sent in a direction approaching the first inclined surface 2a, so that the reel device 16 fixed to the moving wire rope 15 is in the second mooring position indicated by the arrow B. Moved in 5 directions. In this state, the ship S1 is moored at the second mooring position 5.

  In accordance with the same procedure as the first mooring line connecting device 12, the ship S2 is moored by the second mooring line connecting device 22 at the third mooring position 6 which is the water area near the second inclined surface 2b. Then, with the ship S2 engaged with the hook 26b of the mooring line 26a, the ship 26 is moved away from the third mooring position 6 and the ship S2 corresponding to the substantially central water area of the reservoir 1 is moved away. The reel device 26 is moved to the fourth mooring position 7 indicated by the arrow D by driving in the forward direction to approach the fourth mooring position 7, and the ship S2 is moored at the fourth mooring position 7.

  When the water level of the reservoir 1 is lowered due to the discharge of a dam or the like, the mooring lines 16a and 26a wound around the reel devices 16 and 26 by the weight of the ships S1 and S2 connected to the mooring lines 16a and 16b are reels. The fluctuation range of the water level is drawn against the urging force of the spring that urges the devices 16 and 26 in the winding direction, and the ships S1 and S2 descend following the decrease in the water level. At this time, since the sum of the urging force of the spring that urges the reel devices 16 and 26 in the winding direction and the buoyancy acting on the vessels S1 and S2 is equal to the weight of the vessels S1 and S2, the mooring lines 16 and 26 are The tension state is maintained, and the ships S1 and S2 are moored and held at the second mooring position 5 and the fourth mooring position 7.

  On the other hand, as the water level of the reservoir 1 rises, the mooring lines 16a and 26a follow the urging force of the spring that urges the reels 16 and 26 in the direction of winding in the reel devices 16 and 26 by the buoyancy acting on the ship S1 and the ship S2. The ship S1 and the ship S2 rise following the rise in the water level. At this time, the sum of the urging force of the spring urging in the winding direction in the reel devices 16 and 26 and the buoyancy acting on the ship S1 and the ship S2 is equal to the weight of the ship S1 and the ship S2, so the mooring lines 16a, 26a is kept in tension, and the ships S1 and S2 are moored and held at the second mooring position 5 and the fourth mooring position 7.

  When the ship S1 and the ship S2 moored at the second mooring position 5 and the fourth mooring position 7 are used, the ship S1 is moved from the second mooring position 5 to the first mooring position 4 and the first inclined surface 2a. At the same time, the ship S2 is moved from the fourth mooring position 7 to the third mooring position 6 and brought into contact with the second inclined surface 2b.

Since it is constructed as a facility and an airspace facility and is not submerged in the reservoir 1, the durability of the mooring device 10 can be prevented by preventing the deterioration of the facility due to early corrosion due to the facility being in constant contact with water. The effect similar to 1st Embodiment that ship S can be moored after obtaining the improvement of property is acquired.

  Furthermore, since the second mooring line holding part moving mechanism 22 can be installed by sharing the fixed wire rope 11 with the first mooring line holding part moving mechanism 12, the ship S2 can be moored effectively using the airspace. it can. Accordingly, since one or more ships S1, S2 can be moored at the second mooring position 5 and the fourth mooring position 7, the congestion state based on mooring the ships intensively near the quay is eliminated. The navigation of the ship in the reservoir 1 can be performed smoothly.

In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of invention. For example, in the first embodiment and the second embodiment described above, the case where the water area to which the mooring devices 10 and 30 are applied is the reservoir 1 of a hydroelectric power plant in which the water level fluctuates significantly due to rainfall or the like is described. However, the present invention is not limited to the reservoir 1 and can be applied to a lake, a river, a harbor, or the like as long as it is a water area where the ship S needs to be moored.
