Detailed Description
Hereinafter, various embodiments of the present invention will be described with reference to the drawings as appropriate. In the drawings, the same reference numerals are given to the common components. For convenience of explanation, the drawings are not necessarily described in a correct scale. Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A retractable wire guide tool 1 according to an embodiment of the present invention will be described with reference to fig. 1a, 1b, and 2. Fig. 1a and 1b are views showing an embodiment of the retractable wire guide tool according to the present invention when stored. Fig. 2 is a view showing an embodiment of the extension of the retractable wire guide tool according to the present invention. As shown in the drawings, a retractable wire guide tool 1 according to an embodiment of the present invention includes: a rod tube 3 having a plurality of segments 2; a guide 4 arranged outside each segment 2 a-2 h of the plurality of segments 2 of the rod tube 3; and a coiler seat 5 arranged at the rod root of the rod tube 3, wherein each section 2 b-2 h of the plurality of sections 2 is arranged to be respectively telescopic from the sections 2 a-2 g adjacent to the rod root side 10 of each section.
With the retractable wire guide tool 1 according to one embodiment of the present invention, it is possible to provide a retractable wire guide tool that can stably and safely hold a wire in a wire guide used for a flying object such as an unmanned aerial vehicle.
As shown in fig. 1 and 2, rod tube 3 is composed of a plurality of sections 2, i.e. sections 2a, 2b, 2c, 2d, 2e, 2f, 2g and 2h, which are telescopically connected from rod root side 10 to rod tip side 20. These plurality of segments 2 may be connected in a pull-out manner. Here, although the respective segments 2b, 2c, 2d, 2e, 2f, 2g and 2h are respectively extendable from the respective segments 2a, 2b, 2c, 2d, 2e, 2f and 2g adjacent to the rod root side, the length of the segment from the rod root side of each segment can be arbitrarily set by appropriately using the fixing member so as to be freely adjustable.
In addition, as shown in fig. 2, in the telescopic string guiding tool 1 according to one embodiment of the present invention, each node (nodes 2a to 2h) of the rod tube 3 is formed to have a longer node length than the nodes (nodes 2a to 2g) adjacent to the rod root side 10 of each node (nodes 2b to 2 h). That is, the respective nodes (nodes 2a to 2h) are formed to be gradually longer from the rod root side 10 toward the rod tip side 20.
Next, an example of the length of each node (nodes 2a to 2h) will be described with reference to fig. 3. Here, the 01 th indicates a pitch (corresponding pitch 2h) of the rod tip of the rod tube 3, and the 08 th indicates a pitch (corresponding pitch 2a) of the rod root of the rod tube 3. As shown in the figure, 01 th longest is 1160mm, 08 th shortest is 760 mm. By doing so, the mounting position of the guide described later can be set to a position where interference does not occur when the respective nodes (nodes 2a to 2h) are housed.
In the retractable wire guide tool 1 according to one embodiment of the present invention, the rod tube 3 is formed of a carbon fiber composite material (carbon fiber and resin) or a carbon fiber composite material containing glass fiber.
As shown in fig. 1a and 2, a guide 4 (guides 4a to 4h) for passing a guide wire of a flying object such as an unmanned aerial vehicle is provided at each of a plurality of nodes 2 of a rod tube 3, that is, a node 2a, a node 2b, a node 2c, a node 2d, a node 2e, a node 2f, a node 2g, and a node 2 h.
As shown in fig. 1b, a guide 4 (guide 4h) for passing a guide wire of a flying body such as an unmanned aerial vehicle may be provided only in the rod tip node 2h among the plurality of node 2, i.e., the node 2a, the node 2b, the node 2c, the node 2d, the node 2e, the node 2f, the node 2g, and the node 2h, of the rod tube 3.
In the telescopic string guide tool 1 according to one embodiment of the present invention, a guide may be provided on the outer surface of each of the nodes (nodes 2b to 2h) other than the base of the rod among the plurality of nodes (nodes 2a to 2h) of the rod tube 3.
In the retractable wire guide tool 1 according to one embodiment of the present invention, the segment to which the guide 4 is fixed may be formed longer than the segment adjacent to the rod root side of the segment.
In the retractable wire guide tool 1 according to one embodiment of the present invention, the segment to which the guide 4 is not fixed may be longer than the segment adjacent to the rod root side of the segment.
In the retractable wire guide tool 1 according to one embodiment of the present invention, the segment to which the guide 4 is not fixed may be formed to be shorter or the same as the segment adjacent to the rod root side of the segment.
In the retractable wire guide tool 1 according to the embodiment of the present invention, the guide 4 (the guides 4a to 4h) may be formed of stainless steel, titanium, a carbon fiber composite material or resin and stainless steel or resin and titanium, but is not limited thereto.
Next, a method of attaching the guide 4 in the retractable wire guide tool 1 according to one embodiment of the present invention will be described with reference to fig. 4. In the retractable wire guide tool 1 according to one embodiment of the present invention, the guide 4 is fixed to each node (the nodes 2a to 2h) by a carbon fiber composite material tape or a resin and a cord. In the illustrated example, the leg of the guide 4h is fixed by winding the carbon fiber composite material band 7 around the knot portion 2h of the rod tube 3. Thus, the guide can be freely attached to various joint outer diameters.
As described above, fig. 2 shows a state in which the respective nodes (nodes 2a to 2h) of the retractable wire guide tool 1 according to the embodiment of the present invention are extended. As shown in the drawings, the retractable wire guide tool 1 according to one embodiment of the present invention is configured such that, in a state where each segment (segment 2a to 2h) is extended, the distance between the guide (guide 4a to 4h) of each segment and the adjacent guide is narrowed toward the rod root.
Next, an example of the interval between the guide (guides 4a to 4h) of each node and the adjacent guide in the state where each node (nodes 2a to 2h) is extended will be described with reference to fig. 5. Here, the 01 th indicates a pitch (corresponding pitch 2h) of the rod tip of the rod tube 3, and the 08 th indicates a pitch (corresponding pitch 2a) of the rod root of the rod tube 3. The interval between the 01 th guide (corresponding guide 4h) and the 02 th guide (corresponding guide 4g) is shown between 1 and 2, and the interval between the 06 th guide (corresponding guide 4c) and the 07 th guide (corresponding guide 4b) is shown between 6 and 7.
As shown in the figure, the length is longest between 1 and 2, 1090mm, and shortest between 6 and 7, 755 mm. This can reliably prevent the guide pieces of the adjacent segments from being deformed or detached due to unnecessary collision when the segments (segments 2a to 2h) are stored.
In addition, as described above, the coiler seat 5 is installed on the node 2a of the rod tube 3. The guide members (guide members 4a to 4h) function to support the guide wire while guiding the guide wire by attaching the reel to the reel seat and releasing the guide wire 8 from the reel.
The coiler seat 5 is formed in a plate shape or a tube shape, for example, and is placed on the knot portion 2a of the rod tube 3, but various shapes, sizes, and structural forms are also conceivable. The reel holder 5 is formed of an appropriate material such as a synthetic resin (e.g., polyamide-based synthetic fiber, ABS resin, etc.) or a metal (e.g., SUS, aluminum, titanium, brass, etc.). Fig. 6 shows an example thereof. The coiler base 5 is wound and fixed on the knot part 2a of the rod tube 3 by the carbon fiber composite material belt 7. Thus, the reel seat can be freely mounted for various outer diameters of the nodes. A more detailed description of the reel seat will be omitted.
Next, the rod tube 3 of the retractable wire guide tool 1 according to one embodiment of the present invention will be described in detail.
In the telescopic wire guide tool 1 according to one embodiment of the present invention, when the rod tube 3 is formed of a carbon fiber composite material, the carbon fibers of the carbon fiber composite material include: fibers extending in a fiber direction (fiber direction of 0 °) parallel to the length direction of the rod tube 3; and fibers extending in a fiber direction (90 ° fiber direction) perpendicular to the length direction of the rod tube. This improves the bending strength and buckling strength (crushing strength), respectively.
Fig. 7 shows an example of the basis weight of the fibers extending in the fiber direction (0 ° fiber direction) parallel to the longitudinal direction of the rod tube 3 and the fibers extending in the fiber direction (90 ° fiber direction) perpendicular to the longitudinal direction of the rod tube in the retractable wire guide tool 1 according to one embodiment of the present invention. The 01 th indicates a pitch (corresponding to the pitch 2h) of the rod tip of the rod tube 3, and the 08 th indicates a pitch (corresponding to the pitch 2a) of the rod root of the rod tube 3. As shown, the weight per unit area of the fiber extending in the fiber direction of 0 ° increases from 0.6x to 1.0x with going from 01 th to 08 th. On the other hand, the weight per unit area of the fiber extending in the fiber direction of 90 ° increases from 0.12x to 0.24x with going from 01 th to 08 th. Here, the fiber amount (g) in the fiber direction of 0 ° at the 08 th node is defined as x.
As shown in the drawing, in the retractable wire guide tool 1 according to one embodiment of the present invention, the ratio of the basis weight of the fibers extending in the fiber direction (fiber direction of 0 °) parallel to the longitudinal direction of the rod tube 3 to the basis weight of the fibers extending in the fiber direction (fiber direction of 90 °) perpendicular to the longitudinal direction of the rod tube is 0.20 in 01 th and 0.24 in 08 th. By making the ratio of the weight per unit area in this manner, it is understood that favorable results are obtained in terms of strength and weight.
In the telescopic string guide tool 1 according to one embodiment of the present invention, the ratio of the basis weight of the fibers extending in the fiber direction (0 ° fiber direction) parallel to the longitudinal direction of the rod tube 3 to the basis weight of the fibers extending in the fiber direction (90 ° fiber direction) perpendicular to the longitudinal direction of the rod tube is 0.15 or more. In this way, strength can be maintained for larger deformations with less material.
The telescopic thread guiding tool 1 according to one embodiment of the present invention is configured such that the ratio of the basis weight of the fibers extending in the fiber direction (fiber direction of 0 °) perpendicular to the longitudinal direction of the rod tube to the basis weight of the fibers extending in the fiber direction (fiber direction of 90 °) parallel to the longitudinal direction of the rod tube 3 is 0.20 or more. In this way, strength can be maintained for greater deformation.
The telescopic string guide tool 1 according to one embodiment of the present invention is configured such that the bending rigidity of the rod tip of the rod tube is EITTaking the bending rigidity of the rod root of the rod tube as EIBWhen the total length of the rod tube is L (m),
to satisfy SR ═ EIB/EIT×1/L2In the mode of < 0.6,
respectively determining the bending stiffness EI of the rod tip of said rod tubeTBending rigidity EI of rod root of the rod tubeBThe total length L (m) of the rod tube. In this way, by making the rod tip rigid to the rod root more than a certain level, it is possible to suppress the rod tip from being deflected by its own weight when no load is applied.
In the retractable wire guide tool 1 according to one embodiment of the present invention, when the rod tube 3 is made of a carbon fiber composite material, the modulus of elasticity of the carbon fiber at the rod tip of the rod tube 3 is larger than the modulus of elasticity of the rod root of the rod tube. In this way the stiffness of the rod tip can be increased more effectively.
Finally, an outline of a usage mode of the retractable wire guide tool 1 according to the embodiment of the present invention will be described with reference to fig. 8a and 8 b. In the illustrated example, 3 guide lines 8 for flying a flying body (unmanned aerial vehicle) 14 are provided on a balcony 13 of a building 12, and one end of each guide line 8 is fixed to a floor 15. As a method of fixing the guide wire 8 to the ground 15, a weight or a fixing member is conceivable, but not limited thereto.
As shown in the drawing, 3 retractable wire guide tools 1 according to one embodiment of the present invention are provided on a balcony 13 of a building 12 so as to protrude from the balcony 13, and each retractable wire guide tool 1 is fixed to a support member 16 provided on the balcony 13. The means for securing the respective telescopic wire guide tool 1 to the support member 16, such as weights or fasteners, are contemplated, but other suitable means may be employed. The guide wire 8 is attached so that the other end thereof is supported by the retractable wire guide tool 1 according to the embodiment of the present invention fixed to the support member 16.
Although not shown, more specifically, the guide wire 8 passes through the guide 4h provided in the rod tip node 2h of the rod tube 3 of the retractable wire guide tool 1, further passes through the guide 4g to the guide 4a, and finally is wound around the reel of the reel seat 5 provided in the node 2a to be supported. Thus, the length of the guide wire can be adjusted according to the height of the building. Further, the size and scale may be printed on each segment of the retractable guide tool 1 so that the distance from the tip (for example, the guide position of the rod tip) can be known when each segment of the guide 1 is pulled.
The dimensions, materials, and arrangements of the respective components described in the present specification are not limited to those explicitly described in the embodiments, and the respective components may be changed to have any dimensions, materials, and arrangements included in the scope of the present invention. In addition, components not explicitly described in the present specification may be added to the embodiments described above, and a part of the components described in each embodiment may be omitted.
