Description

  The present invention relates to a floating wire adjusting device and a floating wire installation method for adjusting the tension of a floating wire used, for example, in a course section of a canoe competition.

  Courses such as canoeing are arranged in the sea, lakes, rivers, etc. For the division between courses, a floating wire fixed from the shore is used (for example, see Patent Document 1). FIG. 10 shows a schematic diagram of a canoe competition course installed in a dam lake. (A) is a top view, (b) is a side view. As shown in the figure, each course 100 is partitioned by vertical wires 101. Both ends of the vertical wire 101 are pulled by winches 102 installed on the lake shore. The winch 102 ensures the tension of the vertical wire 101.

Moreover, in order to keep each course width uniform, the vertical wires 101 are connected to each other by a horizontal wire 103. The horizontal wire 103 is disposed substantially perpendicular to the vertical wire 101. Both ends of the horizontal wire 103 are fixed by anchors 105 installed on the lake shore.
Japanese Utility Model Publication No. Hei 6-19773

  Among the vertical wires 101, a section A1 from the lake shore to the course 100 start point and a section A2 from the lake shore to the course 100 end point are provided for fixing the vertical wire 101. Further, in the horizontal wire 103, the section B1 from one lake shore to the nearest course 100 and the section B2 from the other lake shore to the nearest course 100 are provided for fixing the horizontal wire 103. is there. In other words, the sections A1, A2, B1, and B2 are sections that are not directly related to the original functions of the vertical wire 101 and the horizontal wire 103 that divide the course 100. For this reason, the vertical wire 101 and the horizontal wire 103 are useless for the sections A1, A2, B1, and B2.

  Further, in order to install the vertical wire 101 and the horizontal wire 103 in the lake, it is necessary to separately install the winch 102 and the anchor 105 on the lake shore in advance. This installation work is complicated.

  Further, the load applied to the winch 102 varies depending on the water level of the lake surface. For example, the load applied to the winch 102 is different when the water is full (indicated by a solid line in the drawing (b)) and drought (indicated by the dotted line in the drawing (b)). For this reason, it is necessary to use the winch 102 having high reliability with respect to the load.

  The floating wire adjusting device and the floating wire installation method of the present invention have been completed in view of the above problems. Therefore, according to the present invention, there is little wire loss, there is no need to install a structure such as a winch or an anchor on the shore, the floating wire can be installed relatively easily, and the tension of the floating wire can be adjusted relatively easily. It is an object of the present invention to provide a floating wire adjusting device and a floating wire installation method.

  (1) In order to solve the above-described problem, a floating wire adjusting device according to the present invention floats on a water surface and has a first engaging portion, receives buoyancy from the float, and floats on the water or on the water surface. A floating wire connecting portion to which a floating wire to be connected is connected, a float side connector having a second engaging portion, a weight to be submerged in the water bottom, and a third engaging portion connected to the weight. A weight-side connecting tool, and an adjustment wire that engages the first engagement portion, the second engagement portion, and the third engagement portion in this order from the water. The floating wire is adjusted by relaxing the wire.

  According to the floating wire adjusting device of the present invention, the tension of the floating wire can be adjusted by relaxing the adjustment wire. For example, when the water level falls, the distance between the weight at the bottom of the water and the float on the water surface becomes smaller. For this reason, the adjustment wire and the floating wire are loosened. In this case, according to the floating wire adjusting device of the present invention, the slack of the adjusting wire and the floating wire can be removed by pulling the adjustment wire from the water. That is, a desired tension can be applied to the floating wire. For example, even when it is desired to remove the slack of the floating wire while the water level is constant, tension can be applied to the floating wire by pulling the adjustment wire from the water. Thus, according to the floating wire adjusting device of the present invention, the tension of the floating wire can be adjusted relatively easily.

  Further, according to the floating wire adjusting device of the present invention, the weight that is sunk in the bottom of the water serves as a fixed end, and the floating wire is stretched. That is, the floating wire is independent from the shore. Therefore, it is not necessary to separately arrange large structures such as the winch 102 and the anchor 105 on the shore as shown in FIG. Further, due to the independence of the floating wire, it is not necessary to stretch the floating wire in the section from the shore to the water surface as in the sections A1, A2, B1, and B2 in FIG. That is, there is little wire loss.

  (2) Preferably, an auxiliary weight is connected to the float side connector. According to this configuration, the float side connector is pulled upward by the float and downward by the auxiliary weight. For this reason, the underwater stability of a float side connector, ie, a floating wire, becomes high.

  (3) Preferably, a spacer is interposed between the float and the float side connector. According to this configuration, the float side connector, that is, the floating wire can be reliably submerged by the length of the spacer. That is, the installation depth from the water surface of the floating wire can be adjusted to a desired depth.

  (4) Preferably, the weight is preferably composed of a plurality of lightweight weights that can be dropped manually. According to this configuration, the weight can be dropped into water by human power. Therefore, the floating wire can be installed manually.

  (5) Moreover, in order to solve the said subject, the floating wire installation method of this invention is floated on the water surface, has a 1st engaging part, receives the buoyancy from this float, and the connection part for floating wire A float-side coupler having a second engagement portion, a weight sinking to the bottom of the water, a weight-side coupler connected to the weight and having a third engagement portion, and the first engagement from the water. A pair of floating wire adjusting devices, which are interposed between the floating wire connecting portions of the pair of floating wire adjusting devices. A floating wire installation method for installing a floating wire underwater or on a water surface, wherein, among a pair of the floating wire adjustment devices, the weight of one of the floating wire adjustment devices is dropped into water. Starting point weight dropping process, and starting from the weight as the starting point, closer to the weight A wire dropping step of dropping the floating wire into the water, an end point weight dropping step of dropping the weight of the other floating wire adjustment device into the water, A tension adjusting step of adjusting the tension of the floating wire by relaxing each of the adjustment wires of the floating wire adjusting device from above the water.

  The floating wire installation method of the present invention includes a start point weight dropping step, a wire dropping step, an end point weight dropping step, and a tension adjusting step. In the starting point weight dropping step, the weight of one floating wire adjusting device of the pair of floating wire adjusting devices is dropped into water. In the wire dropping step, the floating wire is dropped into the water in order from the one connected to the floating wire adjusting device having the weight while being away from the dropped weight. In the end point weight dropping step, the weight of the floating wire adjusting device connected to the end of the floating wire is dropped into the water. In this way, the pair of floating wire adjusting devices and all the floating wires interposed between them are dropped into the water. In the tension adjustment step, the adjustment wires of the pair of floating wire adjustment devices are each relaxed from the water. Here, the distance between the pair of weights sunk in the bottom of the water is unchanged. For this reason, the tension | tensile_strength of a floating wire is adjusted by relaxation of an adjustment wire.

  According to the floating wire installation method of the present invention, the floating wire is independent from the shore. Therefore, it is not necessary to separately arrange large structures such as the winch 102 and the anchor 105 on the shore. Moreover, there are few wire losses like A1, A2, B1, B2 of above-mentioned FIG.

  According to the present invention, there is little wire loss, there is no need to install a structure such as a winch or an anchor on the shore, a floating wire can be installed relatively easily, and the tension of the floating wire can be adjusted relatively easily. An installed wire adjusting device and a floating wire installation method can be provided.

  Hereinafter, embodiments of a floating wire adjusting device and a floating wire installation method of the present invention will be described.

(1) 1st embodiment First, the structure of the floating wire adjustment apparatus of this embodiment is demonstrated. In FIG. 1, the schematic diagram of the canoe competition course installed in the dam lake by the floating wire adjustment apparatus of this embodiment is shown. (A) is a top view, (b) is a side view of the center course of (a). As shown in the figure, a total of nine courses 1 are installed in the dam lake. Each course 1 is partitioned by a total of ten vertical wires 2. The vertical wire 2 is included in the floating wire according to claim 1. The vertical wire 2 is made of SUS. The diameter of the vertical wire 2 is about φ4 to 6 mm. Both ends of the vertical wire 2 are pulled by the floating wire adjusting devices 3a and 3b, respectively. The tension | tensile_strength of the vertical wire 2 is ensured by these floating wire adjustment apparatuses 3a and 3b. On the vertical wire 2, a hollow spherical wire float 20 made of resin is arranged at predetermined intervals. Due to the buoyancy of the wire float 20, the vertical wire 2 floats substantially parallel to the water surface at a predetermined depth from the water surface.

  Moreover, in order to keep each course width uniform, each vertical wire 2 is connected by the horizontal wire 4. The horizontal wire 4 is disposed substantially perpendicular to the vertical wire 2. The horizontal wire 4 is made of SUS. The diameter of the horizontal wire 4 is about φ4 to 6 mm. A total of three horizontal wires 4 are arranged at the start point, the center point, and the end point of the course 1.

  FIG. 2 shows an enlarged view of the floating wire adjusting device 3a on the start end 21 side in FIG. The configuration of the floating wire adjusting device 3b is the same as the configuration of the floating wire adjusting device 3a. Therefore, the description of the floating wire adjusting device 3b is omitted. As shown in the figure, the floating wire adjusting device 3a mainly includes a float 30a, a float side connector 31a, a weight 32a, a weight side connector 33a, an adjustment wire 34a, an auxiliary weight 35a, and a spacer 36a. .

  The float 30a is made of resin and has a hollow spherical shape. A first engagement hole 300a is formed in the float 30a in the vertical direction. The first engagement hole 300a is included in the first engagement portion of claim 1.

  The float side connector 31a is made of SUS and has a ring shape. The float 30a and the float side coupling tool 31a are made of SUS and connected via a columnar spacer 36a. A floating wire connection ring 310a made of SUS and an auxiliary weight connection ring 311a made of SUS are engaged with the float side connector 31a. The starting end 21 of the vertical wire 2 is connected to the floating wire connection ring 310a. The floating wire connection ring 310 a is included in the floating wire connection portion of claim 1. In addition, a second engagement ring 312a made of SUS is welded to the float side connector 31a. The second engagement ring 312a is included in the second engagement portion of claim 1. The auxiliary weight 35a is connected to the auxiliary weight connection ring 311a. The mass of the auxiliary weight 35a is about 20 to 30 kg.

  The weight 32a includes a total of three lightweight weights 320a. The weight of each lightweight weight 320a is about 15 to 20 kg. The weight side connector 33a is made of SUS and has a ring shape. The weight side connector 33a is included in the third engagement portion of claim 1. A weight connection ring 330a made of SUS is engaged with the weight side coupler 33a. The three lightweight weights 320a are connected to the weight connection ring 330a via wires.

  The adjustment wire 34a is made of resin. The diameter of the adjustment wire 34a is about φ15 to 20 mm. One end of the adjustment wire 34a protrudes above the float 30a from the first engagement hole 300a. A knot (not shown) larger than the diameter of the first engagement hole 300a is formed on the protruding portion of the adjustment wire 34a. By this knot, the protruding portion is suppressed from being drawn into the float 30a. The other end 340a of the adjustment wire 34a passes through the first engagement hole 300a and the second engagement ring 312a and is fixed to the weight side connector 33a.

  Next, the movement at the time of the water level fall of the floating wire adjustment apparatus of this embodiment is demonstrated. When the water level decreases from L1 to L2, the adjustment wire 34a is loosened by the amount corresponding to the water level decrease. Therefore, the vertical wire 2 connected to the adjustment wire 34a via the float side connector 31a is also loosened. Therefore, as shown by the white arrow in FIG. 2, the surplus portion of the adjustment wire 34 a is taken from the boat 5. As shown in the figure, the three lightweight weights 320a are set on the bottom of the lake. For this reason, the three lightweight weights 320a do not move. Therefore, when the surplus portion of the adjustment wire 34a is pulled, the float-side connector 31a is pulled in the direction approaching the lightweight weight 320a, as indicated by the white arrow in the figure. Here, the start end 21 of the vertical wire 2 is connected to the float side connector 31a. For this reason, the vertical wire 2 is also pulled in the direction close to the lightweight weight 320a together with the float side connector 31a. As shown in FIG. 1, the vertical wire 2 is pulled by the same operation in the floating wire adjusting device 3b on the end 22 side of the vertical wire 2 as well. Therefore, the vertical wire 2 is pulled from both ends.

  In FIG. 3, the enlarged view of the floating wire adjustment apparatus after taking over the excess part of an adjustment wire is shown. As shown in the figure, the distance between the second engagement ring 312a and the weight side connector 33a is narrowed from D1 to D2 in FIG. The excess portion of the adjustment wire 34a is drawn upward from the first engagement hole 300a by the narrowed amount. Further, a knot larger than the diameter of the first engagement hole 300a is formed in the surplus so that the adjustment wire 34a does not loosen again, that is, the surplus of the adjustment wire 34a does not return into the first engagement hole 300a. Is formed. A desired tension is applied to the vertical wire 2 by pulling the surplus of the adjustment wire 34a.

  Next, the case where a vertical wire is installed by the floating wire installation method of this embodiment is demonstrated. The floating wire installation method includes a start point weight dropping step, a wire dropping step, an end point weight dropping step, and a tension adjusting step. In the starting weight dropping step, as shown in FIG. 4, each member constituting the floating wire adjusting device 3a is dropped into the water from the boat 5a by human power. The three lightweight weights 320a are individually dropped into the water. Thus, the entire floating wire adjusting device 3a is placed in the water. In the wire dropping step, as shown in FIGS. 4 and 5, the boat 5a is moved to the opposite shore starting from the weight 32a. At this time, the vertical wire 2 is dropped into the water in order from the start end 21 connected to the floating wire adjusting device 3a. The dropped vertical wire 2 drifts underwater due to the buoyancy of the wire float 20. In the end point weight dropping step, as shown in FIG. 5, each member constituting the floating wire adjusting device 3b connected to the end 22 of the vertical wire 2 is dropped into the water from the boat 5a by human power. The three lightweight weights 320b are individually dropped into the water. Thus, all of the floating wire adjusting device 3a, the vertical wire 2, and the floating wire adjusting device 3b are disposed in the water. In the tension adjusting step, as shown in FIG. 6, the surplus portion of the adjusting wire 34a is pulled from the boat 5b by human power. FIG. 7 shows an enlarged view of the floating wire adjusting device 3a of FIG. As shown in the figure, the three lightweight weights 320a are set on the bottom of the lake. For this reason, the three lightweight weights 320a do not move. Therefore, when the surplus portion of the adjustment wire 34a is pulled from the boat 5b, the float side connector 31a is pulled in a direction close to the lightweight weight 320a. Here, the start end 21 of the vertical wire 2 is connected to the float side connector 31a. For this reason, the vertical wire 2 is also pulled in the direction close to the lightweight weight 320a together with the float side connector 31a. As shown in FIG. 6, the vertical wire 2 is pulled from the boat 5a by the same operation in the floating wire adjusting device 3b on the end 22 side of the vertical wire 2 as well. Therefore, the vertical wire 2 is pulled from both ends. In this way, a desired tension is applied to the vertical wire 2. When a desired tension is obtained, a knot larger than the diameter of the first engagement hole is formed at one end of each adjustment wire 34a, 34b so that the adjustment wires 34a, 34b do not loosen.

  Next, effects of the floating wire adjusting device and the floating wire installation method of the present embodiment will be described. According to the floating wire adjustment devices 3a and 3b of the present embodiment, the tension of the vertical wire 2 can be adjusted by relaxing the adjustment wires 34a and 34b. For this reason, a desired tension can be applied to the vertical wire 2 relatively easily regardless of the water level.

  Further, according to the floating wire adjusting devices 3a and 3b of the present embodiment, the weights 32a and 32b set in the bottom of the water serve as fixed ends and the vertical wire 2 is stretched. For this reason, it is not necessary to stretch the vertical wire 2 using a winch or the like arranged on the shore. That is, the vertical wire 2 is independent from the shore. Therefore, it is not necessary to separately arrange a large structure such as a winch on the shore.

  Moreover, according to the floating wire adjusting devices 3a and 3b of the present embodiment, the independence of the vertical wire 2 with respect to the shore is ensured. For this reason, there is no wire loss like the section A1, A2, B1, B2 of FIG.

  Further, the sections A1, A2, B1, and B2 in FIG. 10 are arranged on the water. For this reason, when the canoe turns at the end of the course 100, there is a possibility of interfering with the sections A1, A2, B1, and B2. On the other hand, according to the floating wire adjusting devices 3a and 3b of the present embodiment, the vertical wire 2 is submerged over the entire length. For this reason, there is no possibility that the canoe interferes with the vertical wire 2 during the turn.

  Moreover, the auxiliary | assistant weight 35a is connected to the float side coupling tool 31a of the floating wire adjustment apparatus 3a of this embodiment. The float side connector 31a is pulled upward by the float 30a and downward by the auxiliary weight 35a. For this reason, the underwater stability of the float side connector 31a and the vertical wire 2 is high.

  In addition, a spacer 36a is interposed between the float 30a and the float-side connector 31a of the floating wire adjusting device 3a of the present embodiment. For this reason, the float side connector 31a, that is, the vertical wire 2 can be reliably submerged by the length of the spacer 36a. That is, the installation depth of the vertical wire 2 from the water surface can be adjusted to a desired depth so that the canoe paddle does not interfere.

  Further, the weights 32a and 32b of the floating wire adjusting devices 3a and 3b of the present embodiment are subdivided into three lightweight weights 320a and 320b of about 15 to 20 kg, respectively. For this reason, the vertical wire 2 can be installed manually. The reason why the weight of the lightweight weights 320a and 320b is set to 15 kg or more is that when the weight is less than 15 kg, when the tension is applied to the vertical wire 2, the lightened weights 320a and 320b may move on the lake bottom. On the other hand, the reason why the weights of the lightweight weights 320a and 320b are set to 20 kg or less is that when it exceeds 20 kg, it is difficult to drop the weights manually. The wire connecting the lightweight weight 320a and the weight connection ring 330a is set to a length equal to or greater than the water depth when the weight is dropped.

  Moreover, according to the floating wire installation method of this embodiment, the vertical wire 2 can be stretched only by the boats 5a and 5b and human power. That is, the course 1 can be set up. Therefore, a large structure such as a winch is not necessary. Moreover, according to the floating wire installation method of this embodiment, the vertical wire 2 is independent from the shore. For this reason, courses of any layout can be installed without being restricted by the shape of the shore.

(2) Second embodiment The difference between this embodiment and the first embodiment is that the floating wire adjusting device and the floating wire installation method of the present invention are used for the horizontal wire, not the vertical wire. . Therefore, only the differences will be described here.

  In FIG. 8, the upper surface schematic diagram of the canoe competition course installed in the river by the floating wire adjustment apparatus of this embodiment is shown. In addition, about the site | part corresponding to FIG. 1, it shows with the same code | symbol. As shown in the figure, a pair of floating wire adjusting devices 3 c and 3 d are arranged at both ends of the horizontal wire 4. The horizontal wire 4 is included in the floating wire according to claim 1. The tension | tensile_strength of the horizontal wire 4 is ensured by these floating wire adjustment apparatuses 3c and 3d. The horizontal wire 4 is provided with a hollow spherical wire float 40 made of resin at predetermined intervals. Due to the buoyancy of the wire float 40, the horizontal wire 4 floats substantially parallel to the water surface at a predetermined depth from the water surface. The tension | tensile_strength of the horizontal wire 4 is adjusted similarly to the vertical wire of 1st embodiment. Moreover, the horizontal wire 4 is installed by the method similar to the vertical wire of 1st embodiment. Further, the floating wire adjusting devices 3c and 3d and the floating wire installation method of the present embodiment have the same effects as the floating wire adjustment device and the floating wire installation method of the first embodiment.

(3) Third Embodiment The difference between the present embodiment and the first embodiment is that the adjustment wire is folded back by the weight side connector and fixed to the float side connector. In addition, a cylindrical spacer is used. Therefore, only the differences will be described here.

In addition, about the site | part corresponding to FIG. 2, it shows with the same code | symbol. In addition, the configuration of the floating wire adjusting device on the end side is the same as the configuration of the floating wire adjusting device on the starting end side described below. Therefore, the explanation is omitted.

  As shown in the drawing, the adjustment wire 34a is folded back by the weight side connector 33a and fixed to the float side connector 31a. In other words, the adjustment wire connecting portion 313a is disposed on the float side connector 31a. Moreover, the float 30a and the float side coupling tool 31a are connected by the connection wire 301a. The connection wire 301a is provided with a cylindrical spacer 36a made of SUS.

  When the adjustment wire 34a is pulled from above the float 30a, the tension is transmitted to the vertical wire 2 through the adjustment wire connecting portion 313a and the float side coupling tool 31a as indicated by the white arrow in the figure. That is, the tension of the vertical wire 2 can be adjusted. The vertical wire 2 is installed by the same method as the vertical wire of the first embodiment. Further, the floating wire adjusting device and the floating wire installation method of the present embodiment have the same effects as the floating wire adjustment device and the floating wire installation method of the first embodiment.

It may be in the form of a tape. Further, the thin wires may be bundled. Further, it may be a chain. Further, the shapes of the first engagement portion, the second engagement portion, and the third engagement portion are not particularly limited. For example, a hook shape may be used. Moreover, in the said embodiment, although the linear course 1 was installed, you may install the course curved, for example in arc shape. In addition, the floating wire adjusting device and the floating wire installation method of the present invention can be used not only for canoe courses but also for courses such as jet skis and boats. Moreover, it can use not only for course installation but when installing a wire for aquaculture such as seaweed.
