The driving may be performed according to the brightness and the presence or absence of an object.

The rotating shaft 42 of the motor 40 protrudes outward from the lower end 32a of the case 32. The rotating shaft 42 protrudes from the lower end portion 12 a of the housing cylinder member 12 in the assembled state of the harmful animal repellent device 10, and protrudes from the upper end portion 14 b of the sound generating cylinder member 14 toward the inside of the sound generating cylinder member 14. A disc-shaped metal pulley 43 is coaxially fixed to the protruding tip of the rotating shaft 42. In the peripheral portion of the pulley 43, a plurality of, for example, four hole portions 43a penetrating in the thickness direction, that is, the vertical direction are formed. The four hole portions 43 a are provided at equal intervals along the circumference of the pulley 43.

The base end portion of the coil spring 44 is connected to the pulley 43, the tip end portion hangs down, and a synthetic resin weight 46 is attached to the hanged tip end portion. The weight 46 is made of, for example, ABS resin by injection molding, is a sphere having a diameter of 14 mm, and has a weight of 2 g. The weight 46 generates a sound of about 200 Hz to 800 Hz when it collides with the sound generating cylinder member 14. The coil spring 44 and the weight 46 are located inside the sound generating cylinder member 14 and can swing freely. The other three holes 43a of the pulley 43 are spares when the holes 43a are damaged due to long-term use.

In the method for assembling the harmful animal repellent device 10 of this embodiment, first, the housing cylinder member 12 is inserted from the lower end portion 14 a of the sound generating cylinder member 14, inserted through the through-hole 22, and drawn upward, and the flange portion of the housing cylinder member 12. 15 is fitted and positioned in a rectangular recess 24a on the lower surface side of the step portion 24 of the sound generating cylinder member 14. Then, the screw 18 is inserted into the insertion hole 28 formed in the step portion 24, and the tip end of the screw 18 is screwed into the screw hole formed in the flange portion 15 of the housing cylinder member 12 to be locked together. A battery 36, a pulley 43, a coil spring 44, a weight 46, and a cap 16 are attached to the case 32, inserted from the upper end portion 12b of the housing cylinder member 12, and the cap 16 is locked to the upper end portion 12b of the housing cylinder member 12. The coil spring 44 and the weight 46 are slidably positioned inside the sound generating cylinder member 14, and the assembly is completed.

When using the harmful animal repellent device 10 of this embodiment, for example, as shown in FIG. 4, it is provided suspended from a tripod 60 which is a leg member placed on the ground. The tripod 60 has three struts 60a, the upper end portion is bundled by a bundling member 60b, and three

ring members

60c, 60d, 60e of different sizes are provided outside the strut 60a with the lower end portion widened. Are attached at a distance from each other up and down to maintain the shape of a tripod. An S-shaped hook 62 made of stainless steel or the like is attached to the upper end portion of the harmful animal repellent device 10, and the S-shaped hook 62 is suspended by the string body 64 near the binding member 60 b of the tripod 60. As a result, the harmful animal repellent device 10 is suspended inside the three columns 60a and the three

ring members

60c, 60d, and 60e, and the lower end portion 14a is positioned slightly closer to the ground than half the height of the tripod 60. Reached and held.

One end of a wire 66, which is a connecting and holding member having an appropriate length, is attached to the sound generating cylinder member 14, and the other end of the wire 66 is wound around the support 60a of the tripod 60 and the

ring members

60c and 60d. Install. Three wires 66 are attached in the radial direction around the sound generating cylinder member 14, and the sound generating cylinder member 14 is held so as to hang down in accordance with the central axis of the tripod 60. A connecting protrusion 68 for connecting through the wire 66 may be provided on the side peripheral surface of the fitting tube portion 26 of the sound generating tube member 14. In addition, the side surface of the accommodation cylinder member 12 or the sound generation cylinder member 14 may be held on a tripod 60 that is a leg member by a connection holding member such as a plurality of wires 66. Preferably, the connection holding member is connected to the fitting tube portion 26 of the sound generating tube member 14 and the housing tube member 12 and is held by the leg member.

Next, the operation of the harmful animal repellent device 10 will be described. First, when a switch (not shown) is turned on, the motor 40 rotates, and the pulley 43, the coil spring 44, and the weight 46 attached to the rotating shaft 42 of the motor 40 rotate at a predetermined rotational speed. The rotation is controlled by the control unit 38 so as to operate only in the time zone set by the timer. Further, the rotation operation of the motor 40 is controlled to be intermittently driven. For example, after rotating for 5 seconds, stopping for 30 seconds, rotating for 7 seconds and stopping for 20 seconds. Repeat this. In addition, for example, for a wild boar that moves at night with a light sensor, it may detect that it has become dark and rotate the motor 40. By operating a body temperature sensor that detects the body temperature of an animal such as a wild boar, the body temperature sensor The motor 40 may be set to rotate when the detection signal is issued.

When the motor 40 rotates, centrifugal force due to the rotation acts on the weight 46, the coil spring 44 is extended, and the weight 46 hits the inner peripheral surface of the hexagonal cylinder of the sound generating cylinder member 14 to generate a striking sound. At this time, the weight 46 collides with the sound generating cylinder member 14, and the force acting on the motor 40 changes, the rotational speed of the motor 40, the collision position and timing of the weight 46 are different, and the inside of the sound generating cylinder member 14 is different. The weight 46 does not hit the peripheral surface evenly, and randomly collides with the inner peripheral surface of the sound generating cylinder member 14. As a result, the weight 46 intermittently and irregularly collides with the inner peripheral surface of the hexagonal cylinder and generates an irregular hitting sound, which makes it unpleasant for harmful animals such as wild boars and hakubicins, and can be used to it. Absent. The generated sound is adjusted to the frequency of 200 Hz to 800 Hz, preferably 200 Hz to 500 Hz, by adjusting the rotation speed of the motor 40 and the material and shape of the sound generating cylinder member 14 and the weight 46. When the thickness of the sound generating cylinder member 14 is 1 mm, a sound of about 164 Hz to 706 Hz and about 86.8 db is generated. The generated sound spreads so as to diffuse from the lower opening of the sound generating cylinder member 14 and transmits an irregular sound over a wide range, and it is effective for a long time without accustoming wild animals such as wild boar and hakubishin. maintain.

When the battery 36 of the harmful animal repellent device 10 is exhausted, the cap 16 is removed from the housing cylinder member 12, the case 32 is pulled out, a lid (not shown) of the case 32 is removed, and the battery 36 is replaced with a new one. The hole 43a of the pulley 43 may be worn out due to long-term use and may be cut to the side, but when it is cut, the coil spring 44 is replaced with one of the three spare holes 43a.

According to the harmful animal repellent device of this embodiment, it is possible to generate a sound having a frequency that is less unpleasant for humans and to reliably remove harmful animals with a high repellent effect. Since the sound generating cylinder member 14 and the weight 46 are made of resin, a soft and loud sound can be generated and a low frequency sound of 200 Hz to 800 Hz can be generated. This frequency band is a low sound that is not harsh to humans, but harmful animals are sounds that take repellent behavior and reliably generate warning sounds at the required frequency. Since both the sound generating cylinder member 14 and the weight 46 are made of a synthetic resin which is a softer material than the case of metal, even if the collision is repeated, one of them does not wear out and is durable. In particular, the ABS resin, which is the material of the weight 46, has high durability because it is resistant to friction. When the sound generating cylinder member 14 is a cylinder, the weight 46 continuously hits so as to slide on the inner peripheral surface and no loud sound is generated. However, in the case of a shape with a corner such as a hexagonal cylinder, the weight is more strongly applied to the inner peripheral surface. 46 can collide and generate loud sounds and vibrations. In particular, the hexagonal cylinder has an obtuse angle between adjacent side surfaces, the weight 46 collides with the inner peripheral surface at a small angle, and the angle at which it bounces back is small, so that a smooth and continuous impact sound is generated. The life of the sound generating cylinder member 14 and the weight 46 is also prolonged. In addition, since the bounce angle is small and can rotate smoothly, there is no trouble that the weight 46 and the coil spring 44 bounce upward and become entangled with the pulley 43. The same applies to a pentagonal cylinder, and the angle between adjacent side surfaces is an obtuse angle and can rotate smoothly.

The length of the coil spring 44 changes depending on the strength of the centrifugal force, and the weight 46 does not hit the inner peripheral surface of the hexagonal cylinder of the sound generating cylinder member 14 evenly, and irregular sounds are generated intermittently. For this reason, for harmful animals such as wild boars and hakubishins, which are cowardly and vigilant, the irregular sound invites alertness and maintains the effect of not bringing these harmful animals close to each other for a longer period of time.

Furthermore, it is driven intermittently by the control unit 38, so that no sound is always generated, and from this point, it is quiet and the life is extended. Because it is a low sound that is not harsh to humans, it can be used near a private house and can be used to drive away raccoons and hakubishin that appear near the private house. It should be noted that the same effect can be obtained by reproducing and generating a sound of 200 Hz to 800 Hz, preferably 200 Hz to 500 Hz, in which the sound generated by the harmful animal repellent device is recorded.

Since the pulley 43 is provided with four holes 43a, the coil spring 44 can be used by replacing the spare holes 43a even if the holes 43a are cut by long-term use. The sound generating cylinder member 14 is securely attached to the fitting cylinder portion 26 through which the accommodating cylinder member 12 is inserted. Therefore, the sound generating cylinder member 14 can prevent rolling and vertical vibration with respect to the accommodating cylinder member 12 due to the influence of wind, etc. Sound can be generated stably.

The harmful animal repellent device 10 is inexpensive, can be easily used because it is small and easy to manufacture. The cap 16 can be easily waterproofed, can easily and reliably have water resistance, and can be used outdoors for a long time regardless of the weather. Furthermore, the maintenance is easy, the battery 36 can be replaced and used repeatedly, energy saving and efficient, a warning sound of the necessary frequency and the necessary volume can be output continuously for a long time, and the running cost can be reduced. It is cheap.

In particular, the timer drive by the control unit 38 saves power and saves power, and more efficient drive can be performed by intermittent drive. The motor 40 can be driven in combination with a light sensor or a body temperature sensor, can be operated with higher efficiency, can suppress the generation of useless sounds, extend the battery life, and reduce the number of maintenance.

Further, the harmful animal repellent device 10 is suspended by the S-shaped hook 62 and the string body 64 from the tripod 60, and is securely attached to the

ring members

60c, 60d, and 60e by the connection holding member such as the wire 66. Hold fixed. By attaching to the

ring members

60c, 60d, 60e with a connecting and holding member such as a wire 66, the sound generating cylinder member 14 is prevented from detaching from the accommodating cylinder member 12, and it is effectively prevented from swaying in the wind. The ring member 60d can also prevent the tripod 60 from protruding and shaking. By attaching to the tripod 60, even if the shape of the sound generating cylinder member 14 is large, it is not greatly shaken by the influence of the wind, and a large warning sound can be surely generated. The

ring members

60c, 60d, and 60e firmly fix the tripod 60, and also serve as protection of the sound generating cylinder member 14, so that the harmful animal repellent device 10 can be stably installed. In addition, it can be attached to the tripod 60 with a single touch by the S-shaped hook 62, is easily attached and detached, and does not affect the sound generating cylinder member 14. The S-shaped hook 62 is made of stainless steel and has durability.

The top surface portion 20 and the step portion 24 are vertically provided. The sound generating cylinder member 52 is made of, for example, PP resin or PE resin, and is made by blow molding. The sound generating cylinder member 52 has a thickness of 1 mm to 1.5 mm so that a sound of 200 Hz to 800 Hz, preferably 200 Hz to 500 Hz is generated. The size is, for example, about 13.5 cm at the lower end portion 14a of the four side surfaces forming the square cylinder and about 11.5 cm at the upper end portion 14b, and from the lower end portion 52a to the upper end portion 52b of the sound generating cylinder member 52. The height is about 13 cm. The color is blue that can be recognized by wild boars.

According to the harmful animal repellent device 50 of this embodiment, it is manufactured by the same assembling method as in the above embodiment, is the same usage method, and has the same effect. The connecting cylinder member 12 and the sound generating cylinder member 52 can be connected to each other without using a screw or the like, and the insertion protrusion 56 of the flange portion 54 can be inserted into the insertion hole 58 and can be fixed. Etc. can be assembled easily.

The harmful animal repellent device of the present invention is not limited to the above embodiment, and the shape of the sound generating cylinder member may be a pentagonal cylinder other than a square cylinder or a hexagonal cylinder, and may be a pentagon, hexagon, or octagon. The sound generating cylinder member is particularly preferable when the angle formed between the side surfaces adjacent to each other is greater than 90 degrees and equal to or less than 150 degrees. When the adjacent side surfaces of the sound generating cylinder member are formed in this way, as described above, the angle at which the weight rebounds from the side surface becomes smaller compared to the case of a quadrangle that intersects at right angles, and the weight becomes a rotation axis. There is no harmful effect such as entanglement, and the impact sound is generated continuously and smoothly. Furthermore, the cross-sectional shape of an ellipse, an ellipse, and a semicircle may be sufficient, and what is necessary is just a shape which can emit an impact sound effectively. The sound generating cylinder member and the accommodating cylinder member may be integrally formed with a synthetic resin. The means for suspending the harmful animal repellent device may be other than the locking portion or the S-shaped hook, and the hook for suspending the case on the cap can be appropriately changed. The strength of the coil spring, the weight of the weight, and the number of rotations of the motor can be appropriately changed as long as the weight intermittently hits the sound generating cylinder member so as to generate an impact sound due to impact. The leg member may be other than a tripod, as long as it can suspend the harmful animal repellent device. The power source may be a rechargeable electric ground or a solar cell. The material of the synthetic resin of each member may be other than the above embodiment as long as it generates a sound of 200 Hz to 800 Hz, preferably 200 Hz to 500 Hz.
