Description

  The present invention relates to a nest removal bag used for storing and removing a nest such as a crow, for example, formed on an upper portion of a steel tower such as a power transmission line.

  In recent years, nests of crows and the like made in urban areas have been on the rise, and nesting for power transmission towers is no exception.

  On the other hand, many birds have a habit of nesting during breeding season and abandoning the nest with the nesting of chicks. The abandoned nest easily collapses and falls due to subsequent wind and rain, so it is located in the city area It is necessary to remove the nests created on the top of the transmission line towers for public safety and electrical security.

  As shown in FIGS. 6 and 7, the interior of the crow's nest is about 50 cm to 70 cm in diameter, and the exterior supporting the nest is over 1 m. Not a few. As for the structure of the nest, the interior part is generally composed of hair, feathers, vinyl, soil, etc., and the exterior part is composed of wire materials such as twigs and hangers.

  For this reason, conventionally, when a crow's nest is formed on the top of a steel tower such as a transmission line, in order to remove this nest, an operator carries a bag body for collecting the nest as shown in FIG. The nest was stored in this bag and the nest such as crows was removed.

The bag body has a lace attached around the opening. Further, a back belt is attached to the peripheral wall of the bag body.
nothing special

  However, when a bag as shown in FIG. 5 is used for the operation of removing a nest formed on the top of a steel tower such as a power transmission line as in the prior art, the diameter of the opening of the bag is about 40 cm. Since the large nest cannot be stored as it is, it is necessary to separate the nest's interior and exterior parts or crush the exterior when placing the nest in the bag. The twigs and dust forming the inner and outer parts were scattered and scattered over a wide area around the steel tower.

  The nest of a crow or the like forms its exterior part by assembling twigs and the like, and the interior part is formed by weaving the exterior part, so when the exterior part and interior part are separated, The assembled state can be easily solved. Furthermore, vibration generated when the nest is moved, and contact of the nest with the opening of the bag body also unravels the assembled state of the nest and causes twigs, dust, and the like to fall apart.

  In particular, when the nest is located at the corner of the steel tower, etc., because the tower members are intricate, it is difficult to bring the bag close to the nest, so the amount of movement of the nest during removal increases. The amount of scattered twigs, dust, etc. will increase.

  Further, in a steel tower such as a power transmission line, a plurality of tower members are intricate, so it is often extremely difficult to place a bag at a predetermined position of the steel tower.

  Therefore, in the upper part of the steel tower, a worker for expanding the bag body is required, the work efficiency is low, and the labor cost is high. Specifically, in the upper part of the steel tower, two workers spread the bag near the nest, and another worker moved the nest and dropped the nest into the bag. At this time, there was one observer on the ground, so the whole work was being done by a team of four people.

  Therefore, the present invention was created in view of the existing circumstances as described above, and when performing an operation of removing a nest such as a crow at an upper portion of a steel tower such as a transmission line, the bag body is obtained by a very simple procedure. The nest is expanded and fixed near the nest, and the nest can be stored and removed in the bag without scattering of twigs and dust, etc., reducing the number of workers and shortening the work time, removing the nest An object of the present invention is to provide a nesting bag that dramatically improves the efficiency.

  The nesting removal bag according to the present invention solves the above-described problems by attaching a receiving sheet for preventing scattering of twigs and dust forming the nest to a receptacle of a bag body that stores nests such as crows. did.

  Further, the receiving sheet is separable in the vertical direction, thereby solving the above-described problem.

  Furthermore, since the receiving sheet can be separated / joined through the cut portion, the above-mentioned problem has been solved.

  Moreover, the problem mentioned above was solved by attaching the hook-and-loop fastener to the cut portion of the receiving sheet.

  In addition, the above-mentioned problem has been solved by attaching a plurality of fixing hooks to the receptacle and the receiving sheet of the bag.

  Moreover, the fixing latch was attached to the receptacle and the receiving sheet of the bag body via a string-like elastic member, thereby solving the same problem as described above.

  The nesting removal bag according to the present invention is a twig that has fallen apart because a receiving sheet that prevents scattering of dust such as twigs forming a nest and dust is attached to a receptacle of a bag body that stores nests such as crows. The nest can be removed while receiving the dust or the like by the sheet and preventing the scattering.

  Specifically, when the nest is moved to remove the nest formed on the upper part of the steel tower, the assembly state of the twigs forming the nest is released, and the twigs and dust are separated. Even in such a case, it is possible to prevent the occurrence of a situation where these twigs and dust are received by the receiving sheet and scattered around the steel tower. Therefore, no complaints are received from neighboring residents.

  Further, since the receiving sheet can be separated in the vertical direction, the receiving sheet can be arranged near the nest so as to sandwich the tower member even in a place where a plurality of tower members are intricate.

  That is, if the receiving sheet cannot be separated, the receiving sheet can be unfolded by appropriately selecting the separation state / joining state of the receiving sheet in a place where it is hindered by a plurality of tower members and it is difficult to unfold the receiving sheet. It is.

  Furthermore, since the receiving sheet can be separated / joined through the notch, the separating state / joining state of the receiving sheet is appropriately selected according to the situation of the steel tower to be placed, and twigs, dust, etc. It is possible to immediately create a favorable environment that does not scatter.

  Further, since the hook-and-loop fastener is attached to the cut portion of the receiving sheet, the receiving sheet can be easily separated and joined. Therefore, the worker can separate or join the receiving sheet alone.

  In addition, since a plurality of fixing clasps are attached to the receptacle and the receiving sheet of the bag body, these fixing clasps are hooked on the tower member, and the bag body and the receiving sheet are arranged near the nest. And can be fixed.

  Further, since the fixing latch is attached to the receptacle and the receiving sheet of the bag body via the string-like elastic member, the place where the nest is located at the corner portion of the steel tower, or a plurality of tower members Even in places where there is an intricate relationship, the bag member and the receiving sheet can be fixed near the nest by hooking the fixing latch on the tower member via the elastic member.

  Further, even after the bag body is fixed by the string-like elastic member, it is possible to adjust the position of the receiving port in the front, rear, left and right directions.

  As described above, when the nest removal bag according to the present invention is used, the number of workers and the work time can be reduced, and the efficiency of the nest removal work can be dramatically improved. In other words, if the nest removal bag according to the present invention is used, one worker can place and fix the bag body and the receiving sheet near the nest. Workers no longer need to unfold the bag near the nest. Therefore, it is possible to change from a conventional system of 4 people per team to a system of 2 people per group consisting of a total of 2 people, one on the ground and one on-floor worker.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  The nest removal bag according to the present invention is used for storing and removing a nest Q such as a crow made on a steel tower P such as a power transmission line. It is the main component. As shown in FIG. 1, the bag body 1 is formed in a rectangular shape, for example.

  A receiving sheet 2 is sewn and attached to one side of the receiving opening 1a which is an opening of the bag body 1. The receiving sheet 2 is for preventing scattering of twigs and dust forming a nest Q such as a crow, and is formed in a rectangular band shape.

  The shape of the bag body 1 is not limited to the rectangular shape shown in FIG. 1, and any shape can be used as long as it can accommodate the nest Q. Further, the receiving sheet 2 may have any shape as long as it can reliably receive twigs, dust, and the like. Further, the number of the receiving sheets 2 is not limited to one sheet that is one direction of the receiving opening 1a, and the receiving sheets 2 may be attached in a plurality of directions of the receiving opening 1a, such as two sheets, three sheets, and four sheets. Absent. Further, the receiving sheet 2 may be formed larger than the opening of the bag body 1 in order to reliably receive twigs, dust, and the like forming the nest Q such as a crow.

  And the cut | notch part 3 is provided along the vertical direction of the center part of the receiving sheet 2. As shown in FIG. The cut sheet 3 allows the receiving sheet 2 to be separated in the vertical direction.

  In addition, hook-and-loop fasteners 4 a and 4 b are attached along the cut portions 3. In the surface fasteners 4 a and 4 b, a male surface fastener 4 a is laid on the side edge of one receiving sheet 2 that forms the cut portion 3, and a female surface fastener 4 b is attached to the side edge of the other receiving sheet 2. These hook-and-loop fasteners 4 a and 4 b are formed in small pieces and are disposed along the cut portions 3.

  Even if it is a place where a plurality of tower members constituting the steel tower P are intricate by these hook-and-loop fasteners 4a and 4b, a part of the tower members are sandwiched by the separated receiving sheet 2 and laid along the cut portions 3. By attaching the surface fasteners 4a and 4b to each other, the receiving sheet 2 can be developed.

  In addition, as shown in FIG. 1, eyelets 5 are provided at the four corners of the receptacle 1 a of the bag body 1.
