The tools and devices for removing a bird's nest described in Patent Documents 1 and 2 are preferable because they can remove a bird's nest built on a utility pole or the like without crushing it, but they are actually built on a utility pole or the like. Bird's nests are often made by entwining pillar fittings such as insulators and cross arms, and it is difficult to remove the bird's nest without crushing it. For this reason, in reality, it is often removed like crushing a bird's nest by using an insulating yatsuko or the like.

When removing a bird's nest, there may be eggs in the nest. In this case, the insulated snail is used to grasp and move the eggs, followed by removal of the nest. Immediately after spawning, the shell is especially soft, so it may be crushed when grasped with an insulating yatko. In addition, it may be held by an insulating stick and dropped from a high place when moving. When moving the charging part, it is necessary to move while considering the gripping force, the distance from the charging part, and the risk of dropping, which imposes a heavy burden on the operator.

Many tools and devices for removing bird's nests have been proposed in addition to Patent Documents 1 and 2, but tools and devices for collecting eggs in bird's nests have not been described in prior patent documents. do not have. It is important to collect the eggs in the bird's nest to prevent power line accidents. is not specifically pointed out.

FIG. FIG. 7 is a view showing how eggs 100 in a nest 150 are collected using the bird egg collecting tool 2 of FIG. 6;

FIG. 1 is a perspective view of a bird egg collecting tool 1 according to a first embodiment of the present invention. FIG. 2 is a sectional view of a scooping tool 11 of the bird egg collecting tool 1 and a scooping tool 12 which is a modification thereof. 3 and 4 are diagrams showing how eggs 100 are collected in a nest 150 using the bird egg collecting tool 1, and FIG. It is a figure which shows a mode that it is moving.

A bird egg collecting tool 1 according to the first embodiment of the present invention is a bird egg collecting tool attached to the tip of an insulating operation rod 80 and used, and is a ladle-shaped scoop for scooping eggs 100 in a bird's nest 150. A tool 11, a connecting tool 51 that can be detachably connected to the tip of the insulating operation rod 80, and a connecting rod 31 that connects the scooping tool 11 and the connecting tool 51.

The scooping tool 11 has the shape of a ladle and has a dented central portion and a substantially hemispherical shape. The scooping tool 11 may have any shape as long as the egg 100 in the bird's nest 150 can be easily scooped and the egg 100 does not fall off the scooping tool 11 after being scooped, and is limited to a ladle shape. not something. However, the ladle-shaped scooping tool 11 can be said to be a preferable form in consideration of the shape of the bird's nest 150, the collection of the eggs 100, and the subsequent transfer. Otama-shakushi is also called tamama-shakko or otama.

The scooping tool 11 is made of an insulating member such as hard plastic. This is because the bird egg collecting tool 1 used in this embodiment mainly collects eggs 100 from a nest 150 in a place where there is a risk of power line accidents, such as eggs 100 in a bird's nest 150 built on the top of a utility pole 200. 100 is recovered. The scooping tool 11 may have a multi-layer structure in which a conductive member is covered with an insulating member.

The scooping tool 11 of this embodiment does not have a hole, like the ladle scooping soup. In terms of scooping the eggs 100, the scoop may have many holes, such as a slotted ladle, or may be made of a net, but the eggs 100 in the nest 150 may be cracked. Also, considering the possibility that the egg 100 may break in the scooping tool, it is preferable that there is no hole.

The size (including depth) of the scooping tool 11 is not particularly limited as long as it can reliably scoop the eggs 100 in the bird's nest 150 and move the scooped eggs 100 stably. do not have. In the scooping tool 11 of the present embodiment, the jump-out prevention plate 15 is attached to the upper outer peripheral edge 13 so as to block a part of the opening. The height is H1 (see FIG. ₂ (A)).

In order to stably move the scooped eggs 100, it is preferable that the scooping tool 11 is large and deep. , the scoop 11 should not be unnecessarily large or deep.

The weight of the scooping tool 11 is also not particularly limited, but as long as the egg 100 does not fall, a lightweight one is preferable from the viewpoint of operability.

The scooping tool 11 is attached with a jump-out preventing plate 15 for blocking a part of the upper opening of the scooping tool 11.例文帳に追加The jump-out prevention plate 15 is an arcuate plate made of hard plastic, and is attached so that the arc portion 16 is in contact with the outer peripheral edge 13 of the scooping tool 11 and the linear portion 17 is parallel to the connecting rod 31 in plan view. ing. The width W ₁ of the jump-out prevention plate 15 is about 1/3 to 1/4 of the diameter d ₁ of the scooping tool 11 (see FIG. 2(A)).

The jump-out preventing plate 15 is a lid for preventing the eggs 100 from jumping out of the scooping tool 11 when the bird egg collecting tool 1 is moved to collect the eggs 100 scooped up by the scooping tool 11.例文帳に追加In order to prevent the eggs 100 from jumping out of the scooping tool 11, the jump-out prevention plate 15 should be large. should not be large.

The connecting rod 31 is an insulating rod-like body that connects the scooping tool 11 and the connecting tool 51 , and has one end fixed to the scooping tool 11 and the other end to the tip of the connecting tool 51 . The length of the connecting rod 31 is not particularly limited, and may be any length that is easy to use. The connecting rod 31 used in this embodiment is bendable when a predetermined load is applied, and has a shape retainability capable of retaining its shape even after being bent. The bending direction of the connecting rod 31 is not particularly limited, and can be bent in any direction.

Here, "bendable when a predetermined load is applied" means that the connecting rod 31 is grasped with both hands and bent when force is applied by hand so as to bend the center. It means that the weight of the scooping tool 11 in the inserted state does not bend or displace.

Although a linear rod-shaped body that does not bend easily may be used as the connecting rod 31, if a rod-shaped body that is bendable in any direction and has the property of retaining its shape is used, the insulation operation rod 80 will be Therefore, the scooping tool 11 can be placed at any position and angle, and the eggs 100 in the nest 150 can be easily scooped, which is preferable. As such a rod-shaped body having characteristics of being bendable and shape-retainable, for example, there are a shape-retaining tube made by coating an aluminum rod with polyethylene resin, a metal flexible tube holding type, and the like, and these are commercially available.

The connecting tool 51 is a connecting tool having a twist lock mechanism 52, and is the same as a known one that is conventionally used for a tip tool or the like that is attached to the insulating operation rod 80 and used. The insulating operating rod 80 is also a known insulating operating rod that has been conventionally used. The insulated operating rod 80 is also called a common operating rod.

When using the bird egg collecting tool 1, the bird egg collecting tool 1 is attached to the tip of the insulation operation rod 80 and used. FIG. 3 shows a worker 300 mounted on the aerial work vehicle 400 and collecting the eggs 100 in the bird's nest 150 built on the utility pole 200 . In FIG. 3, the connecting rod 31 is used in a straightened state. On the other hand, in FIG. 4, the connecting rod 31 is used in a bent state, and the eggs 100 in the bird's nest 150 are collected. FIG. 5 is a diagram showing how eggs 100 are collected and moved by the bird egg collecting tool 1. As shown in FIG. Since the bird's egg collecting tool 1 is provided with a jump-out prevention plate 15 for blocking a part of the upper opening of the scooping tool 11, the eggs 100 are not easily jumped out and can be collected safely.

FIG. 2(B) is a cross-sectional view of a scooping tool 12 which is a modification of the scooping tool 11 of the bird egg collecting tool 1. FIG. The scooping tool 12 has the same basic structure as the scooping tool 11, but a thin silicon rubber plate 18 is attached to the inner surface of the scooping tool 12 and the back surface of the jump-out preventing plate 15.例文帳に追加A silicon rubber plate has a large coefficient of friction and flexibility. For this reason, the egg 100 is difficult to move in the scooping tool 12 when it is moved, and the silicon rubber plate 18 functions as a rolling prevention member. Also, even if the egg 100 moves in the scooping tool 12 and hits the jump-out prevention plate 15, the egg 100 is not easily broken. With these, the eggs 100 can be collected stably and with peace of mind.

FIG. 2(C) is a perspective view of a connecting rod 32 that is a modification of the connecting rod 31 of the bird egg collecting tool 1. FIG. The connecting rod 31 has a characteristic of being able to bend in any direction and retain its shape, so that the scooping tool 11 can be placed at any position and at any angle with respect to the insulating operation rod 80 . On the other hand, the connecting rod 32 has a structure in which a plurality of substantially spherical members are connected in a bendable manner, and has characteristics capable of bending in any direction and retaining its shape. By connecting one end of the rod-like body 32 to the scooping tool 11 and the other end to the connecting tool 51, the scooping tool 11 can be placed at an arbitrary position and angle with respect to the insulating operation rod 80. FIG.

FIG. 6 is a perspective view of the bird egg collection tool 2 of the second embodiment of the present invention, and FIG. 7 is a scooping tool 21 of the bird egg collecting tool 2 and its modified examples of the scooping tool 23 and the scooping tool 25. It is a sectional view. FIG. 8 is a diagram showing how bird eggs 100 in a nest 150 are collected using the bird egg collecting tool 2. As shown in FIG. The same components as those of the bird egg collecting tool 1 of the first embodiment shown in FIGS.

The bird egg collection tool 2 of the second embodiment has the same basic configuration as the bird egg collection tool 1 of the first embodiment, but differs firstly in the form of the scooping tool 21 . Like the scooping tool 11, the scooping tool 21 has a ladle shape (substantially hemispherical shape). is provided. The recess 22 does not penetrate the scooping tool 21 .

The concave portion 22 has an elliptical shape in plan view, and is sized to fit a portion of the egg 100 (see FIG. 7A). It is preferable that the shape of the concave portion 22 of the scooping tool 21 has a wide contact surface with the egg 100 that is inserted therein, and that the egg 100 that is inserted in the concave portion 22 can be satisfactorily and stably held. FIG. 7A is a cross-sectional view of the scooping tool 21. The egg 100 is completely accommodated in the concave portion 22 provided in the center of the bottom of the scooping tool 21. It can be seen that it is difficult for 100 to jump out.

When the egg 100 is scooped up with such a scooping tool 21, the egg 100 rolls in the scooping tool 21 and fits into the concave portion 22.例文帳に追加As a result, the eggs 100 are stabilized in the scooping tool 21, and the eggs 100 can be prevented from rolling and jumping out when the bird egg collecting tool 2 is moved. In other words, the concave portion 22 can be said to be means for preventing the egg 100 from jumping out instead of the plate 15 for preventing it from jumping out, and can be said to be a means for preventing the egg 100 from rolling in the scooping tool 21 .

The material, weight, etc. of the scooping tool 21 can be considered in the same manner as the scooping tool 11 of the first embodiment. The size of the scooping tool 21 can also be considered in the same way as the scooping tool 11 of the first embodiment. The plate 15 does not get in the way. Therefore, the scooping tool 21 can be made a little smaller than the scooping tool 11.例文帳に追加

In the scooping tool 21, instead of the concave portion 22, a through hole having a size that does not allow the egg 100 to fall out functions as a means for preventing the egg 100 from jumping out and rolling. However, considering the possibility that the eggs 100 to be collected are cracked or that the eggs 100 are broken in the scooping tool 21, the concave portion 22 is preferable.

The second difference between the bird egg collection tool 2 of the second embodiment and the bird egg collection tool 1 of the first embodiment is the connecting rod 35, and the structure of the connecting rod 35 is the same as that of the first embodiment. Different from bar 31 . The connecting rod 35 used in the bird egg collecting tool 2 of the second embodiment is a straight pipe made of a hard material, and unlike the connecting rod 31, it cannot be bent by manual force.

In the bird egg collecting tool 1 of the first embodiment, the scooping tool 11 can be placed at any position with respect to the insulating operating rod 80 by using a rod-shaped body having characteristics of being able to bend and retain its shape as the connecting rod 31 . make an angle. On the other hand, in the bird egg collecting tool 2 of the second embodiment, the position of the scooping tool 21 with respect to the insulating operating rod 80 is adjusted by providing the connecting mechanism 40 that rotatably connects the connecting rod 35 and the connecting tool 55. The angle can be changed.

The connecting rod 35 is provided with a connecting adapter 38 having a seat portion 37 at the connecting portion with the connecting tool 55 . On the other hand, the connector 55 is provided with a connection adapter 58 having a crown seat portion 57 at the tip of a main body 56 having a twist lock mechanism 52 . Both the connection adapter 38 and the connection adapter 58 have bolt insertion holes in their centers. The connection mechanism 40 is composed of a connection adapter 38 provided on the connection rod 35, a connection adapter 58 provided on the connection tool 55, and a bolt 60 and a nut 61 that connect them.

Since the bird egg collecting tool 2 of the present embodiment has one rotatable connecting part (connecting mechanism), there is a limit to changing the position and angle of the scooping tool 21 with respect to the insulating operation rod 80. Unlike the bird egg collecting tool 1 of the first embodiment, even if the scooping tool 21 catches the nest 150 and applies a load when collecting the eggs 100 in the nest 150, the connecting rod 35 does not deform. easy to use in

In the bird egg collecting tool 2 of the second embodiment, in order to increase the flexibility of the position and angle of the scooping tool 21 with respect to the insulating operation rod 80, the intermediate portion A of the connecting rod 35, or the scooping tool 21 and the connecting rod 35 A connection mechanism similar to the previous connection mechanism 40 may be provided at the connection portion B with the . One or two or more rotatable connecting mechanisms may be provided at the intermediate portion A of the connecting rod 35 . Such a mechanism is called a multi-axis arm or multi-joint in the arm of a machine tool robot, and is widely used.

When using the bird egg collecting tool 2, the bird egg collecting tool 2 is attached to the tip of the insulating operation rod 80 and used. During use, the angle of the scooping tool 21 with respect to the insulating operating rod 80 can be changed as needed (see FIG. 8). Since the connecting rod 35 and the connecting tool 55 are connected by the bolt 60 and the nut 61, it is easy to change the angle of the scooping tool 21 with respect to the insulating operating rod 80. Since 37 and 57 are provided, they are firmly fixed.
