Description

  The present invention relates to a magnetic bird damage prevention hollow body that is provided in a place where bird damage can occur, and that birds avoid retreating by an excited magnetic force.

  It is well known that birds have the ability to feel magnetism sensitively, and lose their sense of direction by disturbing the surrounding magnetic field by a strong magnetic force. However, when the magnetic force is constant, it becomes accustomed and it becomes difficult to obtain a repelling effect. In order to solve such a problem, two ferrite magnet pieces are combined so that the same polar surfaces thereof are opposed or in contact with each other to form a combined magnetic body, and both outer side surfaces of the combined magnetic body are formed. However, the magnetic poles in the vicinity of the outer periphery of the laminated magnetic body are formed at one distance away from the outer peripheral edge by a predetermined distance so that the opposite polarities of the opposite poles or abutting poles are opposite to each other. With the magnetic field of 0 value being used as the base, the magnetic force in both sides is excited or amplified, resulting in the divergence of complex magnetism to the periphery due to the formation of a unique magnetic field, which has a significant impact on the flight of wild birds. There has been disclosed a bird damage prevention magnetic body that causes disturbance in the geomagnetism and exhibits a repelling effect (for example, Patent Document 1).

Japanese Patent Laid-Open No. 11-319442

  However, since a magnetic material such as Patent Document 1 uses a ferrite magnet that is a permanent magnet, there is a risk that the magnetic force excited by the surrounding environment such as the passage of time may decrease. In addition, when an object that adheres to a magnet, such as iron scrap, is attached, it must be removed artificially without coming off naturally, and there is a problem that maintenance is troublesome. In addition, it is only a bird-repelling effect as a bird damage prevention magnetic material, and cannot play any other role.

  The present invention has been made in view of the problems as described above, and exhibits a bird's repellent effect over a long period of time, is less likely to cause a decrease in magnetic force, can be reduced in maintenance work, and other than a bird's repellent effect. It is intended to provide a magnetic bird harm prevention hollow body that can easily have a role.

  In order to achieve the above object, the present invention is configured as follows. That is, the magnetic bird damage prevention hollow body according to the present invention comprises a magnetic material generating means for exciting a magnetic force by energization, a solar cell for generating electric power by irradiating sunlight, and a cylindrical shape. An external body and a cylindrical internal body disposed inside the external body, the magnetic force of the magnetic force generating means is excited using the electric power generated by the solar cell, and the solar cell The magnetic force generating means is housed between the external drive body and the internal drive body, and the inside of the internal drive body is a hollow portion.

  According to the magnetic bird damage prevention hollow body according to the present invention, the magnetic force generating means excites the magnetic force by the electric power generated by the solar cell, so that the magnetic force excited in accordance with the change in sunlight caused by the weather changes. It is possible to exert repelling effects for birds over a long period of time. However, if a coiled dielectric is used for the magnetic force generating means, it is difficult for the magnetic force to decrease, and if no light is received by the solar cell, power is supplied to the magnetic force generating means. Is no longer supplied and the excitation of the magnetic force stops, so that the object adhering to the magnet, such as iron scrap, can be naturally detached, and the maintenance work can be reduced. Moreover, since the inside of the internal combustion body is formed as a hollow portion, various roles can be easily provided using the hollow portion.

  Moreover, if the said solar cell is a dye-sensitized solar cell, it becomes possible to set a color tone with a sensitizing dye according to various roles, and to improve the designability.

  BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a partially broken view showing an embodiment of a magnetic bird harm prevention hollow body according to the present invention. The magnetic bird harm prevention hollow body 10 is provided with a magnetic force generating means 1 for generating a magnetic force. The magnetic force generating means 1 is formed by winding a steel wire as a conductor in a coil shape, and a cylindrical inner body 2. It is wound around the outer peripheral surface of. A hollow portion 4 is provided inside the inner body 2. On the further outside of the magnetic force generating means 1, an external body 3 provided with a solar cell (not shown in the figure) is provided. The inner body 2 and the outer body 3 are made of synthetic resin and prevent the magnetic force excited by the magnetic force generating means 1 from being interfered by the inner body 2 and the outer body 3. By connecting the end portions 11 and 12 of the magnetic force generating means 1 to the solar cell, the electric power generated by the solar cell is passed through the magnetic force generating means 1 to excite the magnetic force. According to Fleming's right-hand rule, if an anode is connected to the end portion 11, a magnetic force is generated downward, and if an anode is connected to the end portion 12, a magnetic force is generated upward. Since a high repellent effect can be obtained by directing the direction in which the magnetic force is generated toward an object that needs to repel birds, the direction is appropriately changed according to the situation where the magnetic bird damage prevention hollow body 10 is installed. You may make it install. Further, it is preferable that the gap between the inner body 2 and the outer body 3 is closed by attaching a lid or the like (not shown) to the upper end.

Further, an electrolyte solution 56 such as an iodine solution is filled between the photoelectrode layer 55 and the counter electrode substrate 54, and electric power is generated by irradiating the photoelectrode layer 55 with sunlight. Between the counter electrode substrate 54 and the electrolyte solution 56, a coating of platinum, carbon or the like is formed, so that a potential difference from the electrode coating formed on the external body 3 is generated. By using such a dye-sensitized solar cell, the solar cell 5 can be formed at a much lower cost than when a silicon-based solar cell is used, and downsizing is easy. Furthermore, it is possible to obtain the external body 3 of various colors and to have excellent design properties.
