Description

  The present invention dissipates negative ions to the surroundings while performing a unique fluctuation operation by natural wind, and thereby, by synergistic effect of visual tanning effect and alertness uplifting effect due to the heterogeneous atmosphere containing negative ions, The present invention relates to a pest-repelling device for power transmission lines designed to avoid flying.

  Crows can be mentioned as birds that have expanded their living areas to urban areas due to omnivorous eating habits and advanced intelligence. A crow is a medium-sized resident bird, and a park with a certain amount of trees is selected as a roost, and it seems that it is performing a certain daily activity within a predetermined range of action centered on the roost. . This makes a significant difference between the district where crows fly and the district where crows do not fly.

  It is well known that the breeding activities of crows adapted to urban areas are extremely smooth, and that the increase in the number is causing new bird damage to urban areas. The main cause of bird damage in urban areas is the scattering damage of garbage from various places due to activities of 2-3 or 5-6 birds, but in the vicinity of crow nesting areas where crows fly in large groups, In temporary resting areas during daily activities, noise damage caused by excrement and squealing cannot be ignored. In addition, as a feature of the behavior of such a crow in a large flying place, it can be mentioned that the crow nests on a power pole or stops on a transmission line.

  In other words, the crows nest on the power pole because of the increasing number of crows, the competition to acquire the nesting place in the nesting place intensified, and the crows that lost this competition began to nest the power pole near the nesting place. It is considered a thing. Also, it is thought that the crows staying on the transmission line would be an action to rest their wings in a place not far from the nest due to a marked increase in alertness of the crows during the nesting season. Note that crows in urban areas lacking suitable nest materials sometimes use metal hangers or the like as the nest material, and therefore nests on power poles present a risk of short-circuit accidents or fires. In most cases, the power transmission line is erected along the sidewalk, and the sidewalk under the power transmission line where crows frequently fly presents a disastrous situation that should be disgusted by fecal damage.

Conventionally, a variety of bird protection tools that mainly target crows have been devised and provided to the market. Examples of what has been published in the literature include the following.
JP 2002-84960 A JP 2004-65233 A Japanese Patent Laid-Open No. 2004-187681

  The idea adopted to repel harmful birds such as crows in conventional bird protection equipment is based on the idea of effectively preventing crows and the like, such as a bird-proof thread and a bird-proof net (patents) Reference 1), those based on the idea of scolding crows by the reflected light of solar rays (see Patent Document 2 and Patent Document 3), and inexplicable forms and movements, trying to scold cautions such as crows It can be roughly classified into three types (see Patent Document 2 and Patent Document 3). However, bird protection equipment composed only of one kind of idea is rare, and the actual situation is that two or more kinds of ideas are used together in an actual product.

  Other special ones include large-scale bird protection equipment that tricks crows and the like by regularly emitting violent sounds that resemble the sound of guns, and pseudo corpses of crows intended to show off. Are known.

  Each of the above-described conventional bird protection tools has been widely used with advantages and disadvantages, and new products are being provided one after another. However, what can be installed on the transmission line is not provided at this time, and the nesting of the utility pole is handled by a patrol on a regular basis by the manager of the transmission facility. The current situation is that crows fly to power lines that cause sidewalk droppings.

  The present invention pays attention to the fact that birds have a very sensitive sensation in the environmental atmosphere as a species attribute, and the idea of negatively ionizing the air atmosphere in the vicinity of a place where birds such as crows are to be repelled, and natural wind In addition to adopting the concept of raising the alertness of crows by a unique fluctuation action by the, the purpose is to provide a bird aversion tool for transmission lines that takes into account the ease of installation for transmission lines.

  As means for achieving this object, the present invention adopts the following configuration.

  According to a first aspect of the present invention, there is provided a pest repelling tool for a power transmission line, a clamp member that grips an intermediate portion of a continuously stretched power transmission line, and a plurality of thin wires that fix a base end portion to the clamp member. The clamp member has a lock mechanism that maintains the clamping posture when gripping the power transmission line, and the fine wire is made of a highly elastic material. The ceramic wind receiving member is formed as a wire, and has negative ion radioactivity. The ceramic wind receiving member receives natural wind and fluctuates using the fine wire as a spring element.

  The pest repellent device according to the above configuration can be attached to an arbitrary position in a manner of clamping an intermediate portion of an existing power transmission line via a clamp member, and can be locked so as not to change its posture by using a lock mechanism. The ceramic wind receiving member of the pest repellent device is attached to the clamp member via a fine wire, and receives wind at the attached position. At this time, since the posture of the clamp member itself does not change, the ceramic wind receiving member that has received the wind deflects the fine wire. When the wind stops, the fine wire tries to return to its original shape by its elastic recovery force, so that a resonance system with a predetermined period is formed with the ceramic wind receiving member as a weight, and the damped vibration is continued for a predetermined time. As a result, the ceramic wind receiving member stirs the surrounding air while performing an inexplicable fluctuation operation due to the damped vibration, and diffuses negative ions. The pest repellent device can repel crows and the like by such a fluctuation operation of the ceramic wind receiving member on the power transmission line and the diffused negative ions.

  According to a second aspect of the present invention, there is provided a pest repellent device for a power transmission line, wherein the clamp member in the above configuration has an inner hole formed continuously in an opening for receiving the power transmission line, and the lock mechanism has a transmission mechanism. It is a screw tightening mechanism that deforms the inner hole of the clamp member that houses the electric wire in a closing direction.

  The bird repellent device according to the above configuration is a simple device for receiving the intermediate portion of the power transmission line into the inner hole through the opening of the clamp member, and then operating the screw tightening mechanism that is a lock mechanism to close the inner hole containing the power transmission line. Depending on the operation, the pest repellent device can be attached to the power transmission line so as not to change its posture.

  According to a third aspect of the present invention, there is provided a pest repellent device for a power transmission line, a clamp member that grips an intermediate portion of a continuously stretched power transmission line, and a plurality of thin wires that fix a base end portion to the clamp member. The clamp member is composed of a pair of sandwiching pieces that sandwich the power transmission line, and the pair of sandwiching pieces are attached in a direction to close the pair of sandwiching pieces. It is combined with a spring member that can be opened and closed, and is provided with an operation portion that can be manually operated in an opening direction against the spring member.

  The pest repelling tool according to the above configuration opens the pair of holding pieces by manually operating the operation portion, and after receiving the power transmission line between the opened holding pieces, the operation of the operation portion is stopped, and then the restoring force of the spring member Since the pair of sandwiching pieces is closed by the above, it is possible to attach the pest repellent device to the power transmission line very easily without requiring a tool or the like.

  According to a fourth aspect of the present invention, there is provided a pest repellent device for power transmission lines, wherein the ceramic wind receiving member in the above configuration is formed by molding fine powder obtained by firing silica at a high temperature into a porous solid shape. It is characterized by.

  The pest repellent device according to the above configuration can be easily manufactured at low cost by using a ceramic wind receiving member made of high-temperature fired fine powder of silica that is easily available and has excellent negative ion generation ability. Since the ceramic air receiving member is formed as a porous solid shape, not only the surface of the ceramic air receiving member but also the internal material can contribute to the generation of negative ions. it can. Therefore, even if it is small in size, a sufficient amount of negative ions can be secured, and the function as a weight for the fine wire for realizing the fluctuation operation can be enhanced.

  According to a fifth aspect of the present invention, the clamp member has an insulating cushion liner on the inside, and clamps the power transmission line through the cushion liner.

  The pest repellent device for a transmission line according to the above configuration is closely attached to the transmission line while the cushion liner is deformed during the clamping operation of the transmission line, so that a reliable clamping operation is realized regardless of the cross-sectional shape of the transmission line. At the same time, since the pest repellent device comes into contact with the power transmission line via the insulating cushion liner, it is possible to avoid a short circuit accident, an electric shock accident, etc. via the pest repellent device.

  The pest repellent device for power transmission lines according to the present invention can be attached to any position of the power transmission line via a clamp member in any posture, and can maintain the posture when attached by a lock mechanism or a spring member. The ceramic wind receiving member in the bird repellent device attached to the power transmission line is capable of performing a fluctuation operation of a predetermined period using the fine wire as a spring element while radiating the negative ions by receiving the natural wind. Due to the dissimilarity of the surrounding atmosphere and fluctuations caused by the crow, it is possible to avoid flying crows, nesting, and excessive access to the transmission line.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a pest repellent device for power transmission lines according to the present invention will be described with reference to the drawings.

  The pest repellent device 10 includes a clamp member 11, a plurality of ceramic wind receiving members 13 attached to the clamp member 11 via fine wires 12, and a lock mechanism 14 (FIGS. 2 and 3).

  The clamp member 11 is an injection molded product of a soft resin material. The clamp member 11 is formed as a result of a ring-shaped grip ring 11A and flange portions 11B and 11B formed at both ends of the grip ring 11A. The clamp member 11 is closed at the flange portion 11B. is there. An inner hole 11J is formed inside the grip ring 11A, and a portion of the flange portion 11B becomes an opening portion 11F of the inner hole. The holding ring 11A can open the opening 11F and receive the power transmission line 53 in the inner hole 11J. A metal nut 11C is press-fitted into one of the flange portions 11B, and the opening portion 11F can be closed by a lock screw 11D that passes through the other flange portion 11B and is screwed into the nut 11C. That is, the pair of flange portions 11B, the nut 11C, and the lock screw 11D constitute a lock mechanism 14 of the clamp member 11.

  A plurality of fine wire strips 12 are implanted in the clamp member 11 </ b> A, and a ceramic wind receiving member 13 is fixed to the tip of each thin wire strip 12.

  Each of the plurality of thin wire strips 12 is formed into a thin wire shape from a highly elastic material. In addition, as the fine wire 12, a commercially available glass fiber wire, carbon graphite wire, piano wire, hard nylon wire, spring stainless wire, resin-coated wire wire and the like can be used as they are. The fine wire 12 of the present embodiment is a hard nylon wire, and is attached using an instantaneous adhesive in a continuous state through the pores 11L provided in the grip ring 11A (FIG. 3). Such an attachment method is effective in preventing the fine wire 12 from falling off.

  Each ceramic wind receiving member 13 is formed in a spherical shape exclusively from the viewpoint of design, and at least one thin wire 12 is attached to the tip thereof. The ceramic wind receiving member 13 is a silicon-based material made of fine powder obtained by firing silica at a high temperature, and is formed into a porous solid shape. This kind of ceramic has a high negative ion radioactivity as is well known. The ceramic wind receiving member 13 is provided with a through hole for inserting the fine wire 12, and the fine wire 12 is inserted into the through hole and fixed using an adhesive.

  The ceramic wind receiving member 13 does not need to be pure ceramics as long as it has sufficient negative ion radioactivity, and is formed by molding or granulating fine silica powder in the presence of an appropriate binder. It suffices if it is formed into an arbitrary shape by molding. However, the weight of the ceramic wind receiving member 13 is set so that the fluctuation operation with a large amplitude continues for a long time in consideration of the length and thickness of the fine wire 12 serving as a spring element for supporting the ceramic wind receiving member 13. .

  That is, it is one point that the pest repellent device 10 of the present invention performs a fluctuation operation in response to natural wind. At this time, when the length of the fine wire 12 is constant, the period of the fluctuation operation becomes longer as the weight of the ceramic wind receiving member 13 increases, and the weight of the ceramic wind receiving member 13 is constant. In this case, the cycle of the fluctuation operation becomes longer as the length of the fine wire 12 is increased. However, if the period of the fluctuation operation is set too long, the amplitude will not continue. A plurality of ceramic wind-receiving members 13 can be attached to each fine wire 12.

  An insulating cushion liner 11K can be attached to the clamp member 11 of the pest repellent 10 (FIG. 4). The cushion liner 11K is made of foamed synthetic rubber, and is adhered to the inside of the grip ring 11A using a strong double-sided tape. The foamed synthetic rubber has a large elastic deformation range, thereby absorbing the difference in thickness and shape of the power transmission line 53 clamped in the grip ring 11A, and greatly expanding the adaptable range of the power transmission line 53 to the size of the grip ring 11A. In addition, the function of preventing electric shock accidents and short circuit accidents during and after the installation to the power transmission line 53 is also exhibited.

  The shape of the ceramic wind receiving member 13 attached to each fine wire 12 is arbitrary (FIG. 5). This is because the negative ion radiation performance of the porous ceramic wind receiving member 13 is substantially determined by the amount of ceramic used and does not depend on the shape. The shape of the ceramic wind receiving member 13 may be determined exclusively in consideration of the design viewpoint and the degree of receiving wind. The ceramic wind receiving member 13 shown in FIG. 5 is formed in a military configuration.

  Moreover, the method of attaching the fine wire 12 to the clamp member 11 does not restrict the present invention (FIG. 5). The thin wire 12 is only required to be attached at a low cost so that it cannot be removed. The fine wire strip 12 shown in the figure is attached by providing a bulging portion 11M on the grip ring 11A of the clamp member 11 and penetrating this portion. In this case, an embedded screw may be inserted into the bulging portion 11M to restrain the fine wire 12 from the orthogonal direction.

  The opening 11F in the grip ring 11A of the clamp member 11 can be in a normally open state in which a closing operation width D1 is set between the pair of flange portions 11B and 11B (FIG. 5). Since the opening 11F is in the normally open state, the amount of deformation of the grip ring 11A when receiving the power transmission line in the inner hole 11J of the grip ring 11A can be reduced. When the predetermined tightening torque with respect to 11D is obtained, the certainty of the mounting operation can be ensured by the remaining closing operation width D1 remaining.

  Furthermore, by attaching the insulating cushion liner 11K to the clamp member 11 of the above form (FIG. 6), it can be adapted to the power transmission line 53 of more various forms, and the power transmission line by the frictional force of the cushion liner 11K. The posture maintenance force of the pest repellent tool 10 against 53 can be increased.

  The pest repellent device 10 for power transmission lines according to the present invention can also be implemented in the following form (FIG. 7).

  The pest repellent device 10 includes a clamp member 21 that grips an intermediate portion of a continuously stretched power transmission line 53, a plurality of thin wire strips 12 that fix a base end portion to an operation portion 21E of the clamp member 21, and a thin wire It comprises a ceramic wind receiving member 13 attached to at least the tip of the strip (FIG. 7), and the configuration of the clamp member 21 is greatly different from the above embodiment. Further, the lock mechanism 14 is not necessarily required.

  The clamp member 21 combines a pair of symmetrical sandwiching pieces 21A and 21A so that they can be opened and closed by a support shaft 21C, and biases the pair of sandwiching pieces 21A and 21A in a closing direction by a spring member 21D attached to the support shaft 21C. Become. Semi-circular cutouts 21H and 21H for positioning the power transmission line 53 are formed inside the front ends of the pair of sandwiching pieces 21A and 21A biased in the closing direction, while being opposite to the support shaft 21C. Operation portions 21E and 21E for opening and closing operations are attached to end portions of the pair of sandwiching pieces 21A and 21A located on the side. The distal end portions of the pair of sandwiching pieces 21A and 21A can be opened against the spring member 21D by operating the operation portions 21E and 21E to approach each other, and the power transmission line 53 can be received and restrained between them.

  The fine wire strips 12 are planted so as not to be pulled out by the respective operation portions 21E, and three ceramic wind receiving members 13 are attached to the respective operation portions 21E via the thin wire strips 12. In the pest repelling tool 10 of this form, the force with which the clamp member 21 restrains the power transmission line 53 is determined by the spring member 21D, and therefore can be easily set by replacing or attaching the spring member 21D. . 7 shows a state in which the pest repellent device 10 is attached in an upright posture with respect to the power transmission line 53, but it is desirable to attach it in an inverted posture from the viewpoint of posture stability.

  The pair of clamping pieces 21A and 21A and the spring member 21D constituting the clamp member 21 can be integrally formed from a single spring plate (FIG. 8). The pair of sandwiching pieces 21A, 21A is formed in a bilaterally symmetrical shape in a state of being inclined via the spring member 21D in an inclined posture approaching toward the tip. The spring member 21D is bent to increase the elastic deformation range, and gripping portions 21F and 21F formed on the outer bulge for gripping the power transmission line 53 are provided at the distal ends of the pair of sandwiching pieces 21A and 21A. ing. A cushion liner 11K made of a rubber plate is attached to the inside of each gripping portion.

  The operation portions 21E and 21E are riveted to the outside of the pair of sandwiching pieces 21A and 21A. At this time, the upper end of the operation portion 21E is positioned above the spring member 21D in order to open the pair of sandwiching pieces 21A and 21A. Each operation portion 21E is attached with a jade-shaped ceramic wind-receiving member 13 via a fine wire 21 that is distributed and planted in the vertical direction. The clamp member 21 in this form has a feature that it can be stably attached even to the power transmission line 53 with a small wire diameter.

  In the pest repellent device 10 shown in any of the above embodiments, it can be easily attached to the power transmission line 53 (FIG. 1). The figure shows a situation in which a stay 51 is installed horizontally near the tip of the utility pole 50 and the transmission lines 53 are supported by three insulators 52 erected on the stay 51. This is the situation found in single-phase three-wire transmission lines or three-phase power transmission lines. In each power transmission line 53, two harmful bird repelling tools 10 are installed using the clamp member 11 with the insulator 52 interposed therebetween. Crows and the like are for selecting the vicinity of the insulator 52 where the power transmission line 53 hardly shakes and flying.

  The installed pest repellent tool 10 ... dissipates negative ions while receiving fluctuations in the wind. A crow or the like is a mechanism in which it is impossible to approach the vicinity of the utility pole 50 due to this strange scene and atmosphere. The pest repellent device 10 also fluctuates even when the vehicle travels nearby even in a windless state. This is considered to be because the running vibration of the car appears to be amplified on the front end side of the utility pole 50.

  The pest repellent device 10 of the present invention has been developed for the purpose of power transmission lines, but other communication wirings as well as fruit trees near the harvest period where crows and the like are conspicuous, especially the size of crows, etc. By attaching to the cherries, lobes, and sprigs of the sweeteners that are suitable for the sweetener, it is possible to eliminate the great effort and expense of covering these fruit trees with a bird net. This is because the pest repellent device 10 has a structure that can be easily attached to an elongated attachment target.
