Description

  The present invention relates to a method for preventing damage to birds and animals that is suitable for protecting trees and the like from birds and animals.

  In general, damage caused by wild birds and beasts in forests is mainly caused by deer and bears. For this reason, various measures such as protective fences, repellents, explosive sounds have been taken conventionally, but the effect is limited, or considerable cost and labor (work) are forced along with implementation, It is effective to be able to obtain a sufficient prevention effect against birds and beasts while avoiding adverse effects on the natural environment, which can be carried out with less cost and labor than before, because the adverse effects on the natural environment due to the occurrence of garbage are pointed out Measures were desired.

Therefore, the present applicant has already proposed a bird and animal damage prevention tool effective for such countermeasures in Japanese Patent Application Laid-Open No. 2002-330691. This bird and animal damage prevention tool is formed into a sheet shape with at least a biodegradable resin and can be wound around a predetermined position of a tree, and formed with at least a biodegradable resin. When it is wound, the band portion is constituted by a fixing portion that can be fixed in a cylindrical shape, so that an adverse effect on the natural environment and a sufficient effect of preventing wildlife are realized.
JP 2002-330691

  However, the above-described bird and animal damage prevention device has the following problems.

  First, since it becomes a simple mode in which a band portion is wound around a tree, the change is scarce. Eventually, the threatening effect gradually decreases due to the familiarity of birds and beasts. On the other hand, there is also known a method of intimidating intimidating by blasting sound, but in this case there is a temporary effect that surprises the birds and beasts, but the point of lack of change is the same. It will gradually decrease.

  Second, it aims to visually intimidate and is effective for directly attached trees, but not so much for other trees. Therefore, it is necessary to attach to a considerable number of trees, and labor and time for installation cannot be ignored. In particular, when mounting, a separate fixing portion for fixing the band portion in a cylindrical shape is required, so that an increase in the number of parts and a troublesome mounting operation are forced.

  An object of the present invention is to provide a method for preventing damage to birds and beasts that solves the problems existing in the background art.

  In order to solve the above-described problems, the method for preventing damage from birds and animals according to the present invention installs a sound source in a predetermined area Z to be protected from birds and beasts. In a predetermined area Z to be installed, a sound generator 1 comprising a solar cell 2 and a power source unit 4 having a battery 3 for charging power generated by the solar cell 2 and a sound generator 5 for generating a human voice, The voice generating device 1 generates a human voice to prevent harm from the birds and beasts A.

  According to the method for preventing damage to birds and animals according to the present invention by such a technique, the following remarkable effects are obtained.

  (1) Since a human voice is generated from the sound generator 1, the human voice rich in change can dramatically increase the threatening effect on the birds and beasts A and avoid the familiarity of the birds and beasts A. The threatening effect can be maintained for a long time.

  (2) Since the birds and beasts A can be threatened over the range where the human voice generated from the sound generator 1 can reach, the total installation quantity for the predetermined area Z can be reduced, and the labor and time for installation can be greatly reduced. It can be easily installed by hanging it on a branch of the tree T.

  According to the method for preventing damage from birds and animals according to the present invention, according to the best mode, the sound generator 5 can be a broadcast receiver R that receives radio broadcasts, TV broadcasts, and the like. Thereby, a human voice with changes can be generated regardless of day or night. Instead of the broadcast receiving unit R, an audio reproducing unit P that reproduces a recorded human voice can also be used. Moreover, the sound generator 5 can intermittently generate a human voice so as to be regular or irregular. As a result, the familiarity with the birds and beasts A can be more effectively avoided, and power saving of the sound generator 1 can be achieved. In addition, the sound generator 1 can be installed with respect to the tree T ... which prevents the harm by the birds and beasts A, and can protect the trees T ... from the birds and beasts A such as a deer and a bear.

  Next, preferred embodiments according to the present invention will be given and described in detail with reference to the drawings.

  First, the audio | voice generator 1 used for implementation of the birds and beasts harm prevention method which concerns on a present Example is demonstrated with reference to FIGS.

  As shown in FIG. 4, the sound generator 1 includes, as a basic configuration, a power source unit 4 including a solar cell 2 and a battery 3 that charges power generated by the solar cell 2, and a sound that generates a human voice. A generator 5 is provided. The sound generating unit 5 further includes a broadcast receiving unit R and a sound output unit 10. The broadcast receiving unit R of the embodiment includes an AM radio receiving unit 11 that receives AM radio broadcasting, an AM antenna 12 connected to the antenna terminal of the AM radio receiving unit 11, and a tuning operation for tuning the AM radio receiving unit 11. The unit 13 is provided. The audio output unit 10 includes an amplifier unit 14 that amplifies the audio signal Vo output from the AM radio reception unit 11, a volume adjustment volume 15 connected to the amplifier unit 14, and a speaker 16 connected to the output terminal of the amplifier unit 14. Prepare. On the other hand, the battery 3 is connected to the AM radio receiving unit 11 and the amplifier unit 14 via the switch unit 17. Moreover, the control part 18 connected to the battery 3 is provided, and this control part 18 carries out ON-OFF control of the switch part 17. FIG.

  On the other hand, in FIG.2 and FIG.3, the external appearance structure of the audio | voice generator 1 is shown. A casing 21 is provided with an upper surface portion 21u inclined obliquely upward and a lower surface portion 21d inclined obliquely downward on the front surface. The solar cell 2 is disposed on the upper surface portion 21u, and a slit portion 22 that faces the speaker 16 is provided on one side of the lower surface portion 21d, and an openable / closable cover portion 23 is provided on the other side of the lower surface portion 21d. Is provided. An operation knob 13 s serving as a tuning operation section 13 and an operation knob 15 s of a volume adjustment volume 15 are disposed inside the cover section 23. In this case, the slit part 22 and the cover part 23 ensure waterproofness with respect to the inside of the casing 21.

  Next, a method for preventing damage to birds and animals according to the present embodiment using such a sound generator 1 will be described with reference to FIGS.

  First, the sound generator 1 is attached to the trunk of an arbitrary tree T as shown in FIG. Specifically, the wire W fixed to the sound generator 1 can be easily attached by winding it around the trunk of the tree T. As for the mounting position, a height that does not reach the birds and beasts A is selected, and a place where the sunlight hits is selected. In this case, the AM radio receiving unit 11 in the sound generating device 1 previously performs tuning by the tuning operation unit 13 (operation knob 13s) so as to be able to receive a broadcast station that is broadcasting at midnight, and the volume adjustment volume 15 ( An appropriate volume is set with the operation knob 15s). Note that it is desirable that the wire W is a metal wire and also serves as the AM antenna 12. The sound generator 1 can also be hung on the branch of the tree T using the wire W. Therefore, the sound output from the sound generator 1 reaches the predetermined area Z, and the threat to the birds and beasts A in the predetermined area Z is possible.

  On the other hand, the operation of the sound generator 1 is as follows. Since the solar cell 2 faces obliquely upward, the solar cell 2 generates power when it hits sunlight, and the generated power is charged in the battery 3. In addition, the control unit 18 generates a random number using a built-in microcomputer or the like, and outputs a random ON-OFF control signal to control the switch 17. In this case, when the switch 17 is turned on, power is supplied to the AM radio receiving unit 11 and the amplifier unit 14, and the sound of the AM broadcast received by the AM radio receiving unit 11 is output from the speaker 16, and when the switch 17 is turned off. The power supply to the AM radio receiving unit 11 and the amplifier unit 14 is cut off, and the audio output from the speaker 16 is stopped.

  Since the switch 17 is ON / OFF controlled at random, the audio signal Vo output from the AM radio receiver 11 is intermittent as shown in FIG. 5, and the time when the audio signal Vo is output and the audio signal Vo are output. Any time that is not performed is a random length. For the time in this case, for example, it is desirable to set a reference length such as several minutes, and to change this length. In addition, it is desirable that the voice output (human voice) is generated randomly (irregularly) as described above, but may be generated periodically if necessary.

  As described above, by intermittently outputting the sound, the familiarity with the birds and beasts A can be avoided more effectively, and the power generation of the sound generator 1 can be achieved. In addition, since AM radio broadcasting is used, it is possible to generate human voices with changes regardless of day and night, dramatically increase the threat to birds and beasts A and avoid the use of birds and beasts A. Therefore, the threatening effect can be maintained for a long time. Furthermore, since the birds and beasts A can be threatened over the range (predetermined area Z) within which the human voice generated from the sound generator 1 can reach, the total installation quantity for the predetermined area Z can be reduced, and the labor and time for installation can be reduced. It can be greatly reduced and can be easily installed by hanging it on a branch of the tree T. Moreover, since the sound generator 1 uses the solar cell 2 and the battery 3, no external power source is required, and the operation continues for a long time in an unmanned state even in a mountainous area.

  As described above, the basic embodiment using the sound generator 1 has been described. However, as shown in FIG. 1, the sound generator 1 and the bird and animal harm prevention tool 50 can be used together. The threatening effect can increase the threatening effect.

  Next, the birds and beasts damage prevention tool 50 is demonstrated with reference to FIG.1 and FIG.6. FIG. 6 shows the overall shape of the bird and animal damage prevention tool 50. The bird and animal damage prevention tool 50 is integrally formed by a net member N using an elastic material. Therefore, when manufacturing, a net member No. having a continuous shape with the same width as shown by a virtual line in FIG. 6 may be prepared, and the bird and animal damage prevention tool 50 having a shape shown by a solid line in FIG. Thus, the bird and animal damage prevention tool 50 can be manufactured very easily.

  As the mesh material No, an elastic material such as a synthetic resin having a predetermined elasticity is used. In this case, a general synthetic resin may be used, but desirably, a biodegradable resin containing a light stabilizer for polymer, for example, a biodegradable resin disclosed in JP-A No. 2002-330691 is used. Can be used. This type of biodegradable resin has the same physical properties as other general synthetic resins (general-purpose resins) under normal use, but it is decomposed into water and carbon dioxide by microorganisms in the natural environment such as soil. The Moreover, a weather resistance is improved by mix | blending a suitable quantity of polymer light stabilizers.

  The wildlife prevention tool 50 includes a first band portion 51 having a strip shape having a width La (for example, about 20 [cm]) and a length Lb (for example, about 40 [cm]). Moreover, while providing the insertion hole 52 in the longitudinal direction one end 51s side of the 1st band part 51, the width Lc (for example, for example) inserted in the said insertion hole 52 in the longitudinal direction other end 51t side of the 1st band part 51 is provided. And a second band portion 53 having a length Ld (for example, about 60 cm). Furthermore, a plurality of elastic protrusions 54 are provided at predetermined intervals along the longitudinal direction on the side portions 53p and 53q on both sides in the width direction of the second band portion 53, respectively. In this case, the length Li from the tip of one elastic protrusion 54 to the tip of the other elastic protrusion 54 in the width direction of the second band 53 is greater than the width direction length Lh of the insertion hole 52. Is also selected so that Li> Lh.

  Such elastic protrusions 54 can be easily provided by selecting a position when the mesh material No is cut off. Moreover, the repelling effect with respect to a bird and beast can be heightened by leaving the protrusion part similar to the elastic protrusion part 54 ... in the side part of the width direction both sides of the 1st band part 51 at the time of cutting | disconnection of net | network material No. In addition, 55 is a guide piece provided at the tip of the second band portion 53, whereby the second band portion 53 can be easily inserted into the insertion hole 52. Further, the bird and animal damage prevention tool 50 can be colored with a high repellent effect against birds and beasts and, if necessary, can be coated (or mixed) with a luminescent paint (phosphorescent pigment) or the like.

  Such a wildlife prevention tool 50 can be used as follows. First, the bird and animal damage prevention tool 50 is taken to the tree (growth) T to be mounted. Then, as shown in FIG. 1, a predetermined position of the tree T visible from the birds and beasts A, preferably about 90 [cm] from the ground corresponding to the height of the eyes for relatively large birds and beasts A such as bears and deers. In addition, the bird and animal damage prevention tool 50 is wound and the second band portion 53 is inserted into the insertion hole 52. At the time of insertion, the elastic protrusions 54 provided on the second band part 53 abut against the edge of the insertion hole 52, but the elastic protrusions 54 elastically deform, so that the second band part 53 is placed against the insertion hole 52. Can be inserted.

  And the 2nd band part 53 is fastened with respect to the penetration hole 52 so that the 1st band part 51 and the 2nd band part 53 closely_contact | adhere to the surface of the tree T. FIG. At this time, since the elastic protrusions 54 that have passed through the insertion hole 52 are elastically restored and locked to the edge of the insertion hole 52, easy removal is prevented. Therefore, the birds and beasts damage prevention tool 50 is hold | maintained in the state wound around the tree T, as shown in FIG. As described above, since the bird and animal damage prevention tool 50 does not require a separate fixing means, it can be mounted very easily and the cost can be reduced by reducing the number of parts.

  As shown in FIG. 1, the attached bird and animal damage prevention tool 50 has a distal end side 53f of the second band portion 53 having a length Ld protruding from the insertion hole 52 and a distal end of the distal end side 53f at the free end. Will be shaken by the wind. Therefore, the bird and animal damage prevention tool 50 is shaped by the first band portion 51 (second band portion 53) wound around the tree T and the distal end side 53f of the second band portion 53 protruding laterally from the tree T. Complicated and has an intimidating effect on birds and beasts A. In other words, the tree T is protected from the habit that the birds and beasts A are not close to artificially added crops. In particular, if the position for mounting the bird and animal damage prevention device 50 is selected to be about 90 cm above the ground, it will be at the eye level for relatively large birds and beasts A such as bears and deer, and more The effect can be enhanced.

  On the other hand, when the tree T grows and becomes thick, the bird and animal damage prevention tool 50 wound around the tree T also follows and spreads, but the elastic protrusions 54... The diameter of the bird and animal damage prevention tool 50 is also increased. In addition, the diameter of the bird and animal damage prevention tool 50 that can be followed at this time can be arbitrarily set by selecting the length Ld of the second band portion 53. Therefore, the breakage of the bird and animal damage prevention tool 50 due to the growth of the tree T can be reliably avoided.

  In addition, since the bird and animal damage prevention tool 50 is formed by the net member N, air permeability is ensured, and internal stuffiness in the wound first band part 51 and second band part 53 is prevented, and sunlight Can pass through and maintain a good natural environment. In addition, if the animal and animal damage prevention device 50 is formed by blending a suitable amount of a light stabilizer for a polymer with a biodegradable resin, weather resistance can be remarkably improved even in an outdoor environment, and long-term wearing is possible. Possible, that is, the effect of preventing damage to birds and beasts can be maintained for a long period of time, and when the tree T is cut down by cutting or the like, the birds and beasts damage prevention device 50 can be left on the ground as it is, so It is decomposed into water and carbon dioxide by microorganisms in the environment and does not adversely affect the natural environment.

  The embodiment has been described in detail above, but the present invention is not limited to such an embodiment, and the detailed configuration, shape, material, quantity, and the like can be arbitrarily set within the scope of the present invention. Can be changed, added, or deleted.

  For example, in the embodiment, since the sound generator 1 is installed in a mountainous area, the broadcast receiving unit R uses the AM radio receiving unit 11 that can receive signals even in a mountainous area. An FM radio receiver, a TV audio receiver, or the like may be used as long as reception is possible. Moreover, although the case where the broadcast receiving part R was utilized for the audio | voice generation part 5 was shown, the audio | voice reproduction | regeneration part which reproduces | regenerates the recorded human voice can also be used. In this case, the broadcast receiving unit R shown in FIG. 4 may be removed and the audio reproducing unit P may be connected instead. Note that a memory in which a human voice is stored in advance can be used for the sound reproducing unit P. In addition, since the human voice means a natural enemy against the bird and beast A, the roar of other animals that are natural enemies may be used together with the human voice or instead of the human voice. Furthermore, although the Example showed the case where the audio | voice generating apparatus 1 was installed with respect to the tree T ... which prevents the harm by the birds and beasts A ... Arbitrary which needs protection from birds and beasts A, such as a field, an orchard, a house, etc. Can be installed in a predetermined area Z. In addition, by installing the sound generators 1 at a plurality of separated positions, the substantial sound source moves corresponding to the position of the bird and beast A, and the threatening effect on the bird and beast A can be further enhanced.
