Description

  The present invention relates to a tower climbing prevention device. In particular, the present invention relates to a structure of an apparatus for preventing an animal such as a cat from ascending a tower mounted on a steel frame, in which a disconnector for opening and closing a voltage of a power circuit is mounted on the upper part.

  For example, an ascending tower prevention member is installed at a height of 3 m to 5 m from the ground to prevent the ascending towers other than those concerned from rising. The climbing prevention member blocks a ladder installed in the steel tower or an elevating passage such as a step bolt, and particularly prevents a climbing tower such as a child. In general, such ascending tower prevention members are known in which a frame is installed in the horizontal direction around the steel tower, or in which rod-like members protrude radially so as to surround the steel tower.

  By the way, when installing a steel tower in a narrow space in an urban area surrounded by private houses or public facilities, it is not preferable to project a climbing prevention member around the steel tower, and the environment around the steel tower is damaged. Since it has a drawback, a tower climbing prevention device is disclosed that is installed in a vertical direction so as to be suitable for narrow spaces (see, for example, Patent Document 1).

  The ascending tower prevention device according to Patent Document 1 is a panel for preventing ascending and descending arranged at an appropriate height of the tower legs constituting the steel tower, and is arranged in a horizontal state inside the steel tower, and a wire mesh is stretched. It comprises a plurality of horizontal blocking panels and a plurality of vertical blocking panels arranged in a vertical state outside the steel tower, and these vertical blocking panels are attached so as to cover the outside of the tower legs.

  The tower climbing prevention apparatus according to Patent Document 1 is configured to open and close a part of the vertical blocking panels that block the lifting passage when a person concerned climbs the tower, and the blocking panels provided on the outer periphery of the steel tower are arranged vertically. It is said that it is suitable for the effective use of the land because the panel which prevents the raising and lowering from overhanging the outside of the steel tower is not excessively installed.

Japanese Utility Model Publication No. 4-62860

  The climbing prevention device according to Patent Document 1 can prevent climbing towers of children other than those concerned. However, referring to Patent Document 1, the central portion inside the steel tower is a space. Moreover, the diagonal material which connects the horizontal material arrange | positioned at the lower part and upper part of the tower base (main pillar material) has penetrated the space inside a steel tower. Therefore, there is a problem that animals such as cats can climb the diagonal and climb the tower.

  For example, a platform with a disconnector installed on top is installed outdoors and a plurality of horizontal members are attached in a ladder shape, so animals such as cats climb these horizontal members from the inside or outside of the platform. Therefore, there is a problem that the tower can be easily climbed. And there is a concern that an animal such as a cat may come into contact with the disconnector to cause a ground fault or a short circuit accident. The above can be said to be the subject of the present invention.

  This invention is made | formed in view of such a subject, and it aims at providing the climbing prevention apparatus which prevents that animals, such as a cat, climb a tower on a mount frame.

  The inventor encloses the adjacent outer surface of the gantry with a pair of vertical panels bent in an L-shape and partitions the interior of the gantry up and down with a partition plate, so that animals such as cats can be seen from outside and inside the gantry. Based on this, the inventors have invented the following new tower prevention apparatus.

  (1) The ascending tower preventing apparatus according to the present invention is composed of a main pillar material standing from the four corners of the base surface having a rectangular outer shape, and a plurality of horizontal members arranged at substantially equal intervals while connecting these main pillar materials. A climbing prevention device that prevents animals from ascending to a pedestal that is framed in a square column shape and has power distribution equipment mounted on the upper part thereof, and is arranged at the upper part of the pedestal so as to surround the adjacent outer surface of the pedestal. And a pair of vertical panels bent in an L shape, and a partition plate arranged in a horizontal state so as to substantially coincide with the lower edges of these vertical panels and partitioning the interior of the gantry up and down.

  (2) It is preferable that the said vertical panel has a hook member which can be latched to the said horizontal member, and an angle member which can attach the said partition plate.

  (3) It is preferable that the tower climbing prevention device according to the present invention further includes a pair of band members that fasten the pair of vertical panels so that the inner surfaces of the pair of vertical panels are in close contact with the outer surface of the gantry.

  (4) It is preferable that the said partition plate consists of a perforated plate or a mesh board.

  Ascending tower prevention apparatus according to the present invention is a main pillar material standing from the four corners of a rectangular base surface, and a combination of these main pillar materials, and a plurality of horizontal members arranged at substantially equal intervals into a square pillar shape. In a frame that is framed and has power distribution equipment on top, a pair of vertical panels bent in an L shape to surround the adjacent outer surface of the frame is placed at the top of the frame. It is possible to prevent animals such as cats from ascending to the power distribution facility from the outside. In addition, since the interior of the gantry is partitioned vertically by partition plates, it is possible to prevent animals such as cats from ascending to the power distribution facility from the inside by climbing these horizontal members.
