[Brief explanation of the drawings]

[0016] [Figure 1] 1 is a schematic diagram of a bird repellent device provided by an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be described in detail below with reference to the drawings. According to the study, birds are afraid of dynamic light beams, and the dynamic reflective light beams can be used to frighten birds and realize bird repellency. Therefore, the present application provides a bird repellent device. Specifically, see the following examples.

[0018] Example 1, the bird repellent device includes a reflective structure 100, a support structure 200, a control line 300, a power structure 400, and a mounting base 500.

[0019] The support structure 200 includes an axial support rack 210 , a support arm 220 , and a triangular metal frame 230 .

[0020] The triangular metal frame 230 is a triangular frame surrounded by metal wire, and the outer side of one corner of the triangular metal frame 230 is fixed to one end of the support arm 220, away from the axial support rack 210. An encircling coil is installed in the triangular metal frame 230. The encircling coil is a circle and is welded to the triangular metal frame 230.

[0021] In the embodiment of the present invention, the triangular metal frame 230 is a triangular frame surrounded by iron or steel wire.

[0022] The reflective structure 100 has a disk shape, and both the front and back surfaces of the reflective structure 100 are coated with a reflective material capable of reflecting light. The back surface of the reflective structure 100 is detachably connected to the triangular metal frame 230. In an embodiment of the present invention, the detachable connection between the back surface of the reflective structure 100 and the triangular metal frame 230 may be a buckle connection, i.e., an engagement groove is provided on the back surface of the reflective structure 100, and the triangular metal frame 230 is inserted into the engagement groove, and the triangular metal frame 230 and the engagement groove are tightly fitted together. The detachable connection between the back surface of the reflective structure 100 and the triangular metal frame 230 may be a buckle provided on the back surface of the reflective structure 100, and the buckle is engaged with the triangular metal frame 230 to secure the triangular metal frame 230 to the reflective structure 100.

[0023] The axial support rack 210 includes a bottom rod 211, a first spring 212, a telescopic rod 213, a second spring 214, and a top rod 215. The telescopic rod 213 is telescopic.

[0024] One end of the support arm 220 is detachably connected to the telescopic rod 213 .

[0025] One end of the bottom rod 211 is detachably connected to the mounting base 500 , and the other end of the bottom rod 211 remote from the mounting base 500 is fixedly connected to one end of the first spring 212 .

[0026] One end of the first spring 212 remote from the bottom rod 211 is detachably connected to one end of the telescopic rod 213. One end of the telescopic rod 213 remote from the first spring 212 is detachably connected to one end of the second spring 214. One end of the second spring 214 remote from the telescopic rod 213 is fixedly connected to the top rod 215.

[0027] The power structure 400 is installed on the telescopic rod 213 and is used to provide telescopic power to the telescopic rod 213 .

[0028] In an embodiment of the present invention, the control wire 300 may be a thin metal wire such as a steel wire, an iron wire, a stainless steel wire, an aluminum wire, etc. The control wire 300 may also be a flexible wire such as a rubber wire.

[0029] By adopting the above technical solution, the power structure 400 supplies power to the telescopic rod 213 once, stretching the telescopic rod 213 and compressing the first spring 212 and the second spring 214. After the power supply is stopped, the rebound process of the first spring 212 and the second spring 214 causes the telescopic rod 213 to vibrate, which in turn syncs with the vibration of the reflective structure 100, allowing the reflective structure 100 to dynamically reflect light and drive away nearby birds. In addition, one end of the control wire 300 is fixed to the top rod 215, and the other end is fixed to the bottom rod 211 after passing through the through coil. The control wire 300 is kept in a taut state, and the rebound process of the first spring 212 and the second spring 214 causes the control wire 300 to vibrate. As the control wire 300 becomes taut, it comes into contact with the triangular metal frame 230 (contact with the through coil). As the control wire 300 vibrates, the vibration frequency of the reflective structure 100 is further improved. Both forces drive the vibration of the reflective structure 100 and reinforce the vibration of the reflective structure 100. This improves the ability, frequency and duration of the reflective structure 100 to reflect light, thereby improving the bird-repelling effect. Compared to the prior art, which requires continuous power to vibrate the reflective structure 100, the bird repellent device provided by the embodiment of the present invention saves energy, i.e., it provides power only once and extends the vibration time of the reflective structure, thereby saving energy and improving the bird-repelling effect.

[0030] Optionally, the telescopic rod 213 includes an inner rod 2131 and an outer rod 2132 .

[0031] An end of the first spring 212 remote from the bottom rod 211 is detachably connected to a first end of the inner rod 2131 .

[0032] The outer rod 2132 is a hollow rod having a hollow cavity along the axial direction of the outer rod 2132, and the second end of the inner rod 2131 extends into the hollow cavity, thereby enabling the inner rod 2131 to expand and contract along the axial direction of the outer rod 2132. The second end is one end of the inner rod 2131 remote from the first spring 212.

[0033] The length of the hollow cavity is greater than the length of the inner rod 2131 .

[0034] The power structure 400 is disposed within the hollow cavity away from the first end and is detachably connected to the second end.

[0035] The power structure 400 is used to provide the inner rod 2131 with extension and retraction power.

[0036] In an embodiment of the present invention, the power structure may include an airbag and an inflator. The airbag is installed in the hollow cavity inside the outer rod 2132 and is detachably connected to the second end of the rod 2131. The airbag is made of a flexible material.

[0037] The outer rod 2132 has a small hole through which a power line passes, with one end connected to the inflator and the other end connected to a power source. Power is supplied to the inflator through the power line, which then fills the airbag with air. This causes the inner rod 2131 to extend the outer rod 2132, compressing the first spring 212 and the second spring 214. After the power supply is stopped, the first spring 212 and the second spring 214 recoil, compressing the airbag and deflating it. At the same time, the first spring 212 and the second spring 214 recoil, causing the telescopic rod 213 to vibrate. This allows the vibration of the reflective structure 100 to dynamically reflect the reflected light, which can frighten and scare away nearby birds.

[0038] Optionally, one end of the support arm 220 is detachably connected to the outer wall of the outer rod 2132 .

[0039] Optionally, the plane on which the reflecting structure 100 is located is parallel to the axial direction of the telescopic rod 213 .

[0040] Alternatively, the reflecting structure 100 may be a plurality of pieces, the support arms 220 may be a plurality of pieces, each reflecting structure 100 may be mounted on one support arm 220, and the reflecting structure 100 may be connected to the support arm 220 by one triangular metal frame 230.

[0041] Optionally, the number of support arms 220 is eight, and the eight support arms 220 are a first support arm 221, a second support arm 222, a third support arm 223, a fourth support arm 224, a fifth support arm, a sixth support arm, a seventh support arm and an eighth support arm, respectively.

[0042] Here, the first support arm 221 and the second support arm 222 are installed in a first direction of the telescopic rod 213. The third support arm 223 and the fourth support arm 224 are installed in a second direction of the telescopic rod 213. The fifth support arm and the sixth support arm are installed in a third direction of the telescopic rod 213. The seventh support arm and the eighth support arm are installed in a fourth direction of the telescopic rod 213. The first and third directions are opposite to each other in a first plane, and the second and fourth directions are opposite to each other in a second plane. The first plane is perpendicular to the second plane and intersects with the axis of the telescopic rod 213. The axis is parallel to the first and second planes.

[0043] Optionally, the first support arm 221 is disposed on a first axis between the first support arm 221 and a fourth support arm 224. The fourth support arm 224 is disposed on a second axis between the first support arm 221 and a second support arm 222. The fifth support arm is disposed on a third axis between the seventh support arm and an eighth support arm. The eighth support arm is disposed on a fourth axis between the fifth support arm and a sixth support arm.

[0044] The first axis and the second axis are parallel in a plane, and the first axis is parallel to the linear extension line on which the second support arm 222 is located, the linear extension line on which the third support arm 223 is located, and the linear extension line on which the fourth support arm 224 is located, while the second axis is parallel to the linear extension line on which the first support arm 221 is located, the linear extension line on which the second support arm 222 is located, and the linear extension line on which the third support arm 223 is located.

[0045] Alternatively, the support arm 220 may be installed at an acute angle to the telescopic rod 213 , or may be installed perpendicular to the telescopic rod 213 .

[0046] One reflective structure 100 is installed on each support arm 220, that is, there are correspondingly eight reflective structures 100, and the eight reflective structures 100 are respectively the first reflective structure 101, the second reflective structure 102, the third reflective structure 103, the fourth reflective structure 104, the fifth reflective structure 105, the sixth reflective structure 106, the seventh reflective structure 107, and the eighth reflective structure 108. The first reflecting structure 101 is mounted on the first support arm 221, the second reflecting structure 102 is mounted on the second support arm 222, the third reflecting structure 103 is mounted on the third support arm 223, the fourth reflecting structure 104 is mounted on the fourth support arm 224, the fifth reflecting structure 105 is mounted on the fifth support arm, the sixth reflecting structure 106 is mounted on the sixth support arm, the seventh reflecting structure 107 is mounted on the seventh support arm, and the eighth reflecting structure 108 is mounted on the eighth support arm.

[0047] 1, the fifth support arm, the sixth support arm, the seventh support arm, and the eighth support arm cannot be shown because they are respectively shielded by the fifth reflecting structure 105 and the sixth reflecting structure 106. In fact, the shapes and properties of the fifth support arm, the sixth support arm, the seventh support arm, and the eighth support arm are the same as the shapes and properties of the first support arm 221, the second support arm 222, the third support arm 223, and the fourth support arm 224.

[0048] By adopting the above technical solution, the plane on which each reflective structure 100 is located is parallel to the telescopic rod 213. First, light may be reflected by the front surface of each reflective structure 100 or by the back surface of the reflective structure 100. Furthermore, light incident at an acute angle will be reflected by the back surface of the third reflective structure 103 to the back surface of the first reflective structure 101, then via the back surface of the first reflective structure 101 to the back surface of the fourth reflective structure 104, further via the back surface of the fourth reflective structure 104 to the back surface of the second reflective structure 102, and finally reflected downwards toward the bird repellent device via the second reflective structure 102. Similarly, the light may be reflected by the rear surface of the seventh reflecting structure 107 to the rear surface of the fifth reflecting structure 105, then reflected by the rear surface of the fifth reflecting structure 105 to the rear surface of the eighth reflecting structure 108, then reflected by the rear surface of the eighth reflecting structure 108 to the rear surface of the sixth reflecting structure 106, and finally reflected downwards by the sixth reflecting structure 106. Adding a reflecting structure 100 to the top rod 215 of the bird repellent device allows the bird repellent device to reflect light in all directions, i.e., to reflect light in all directions and repel birds in all directions, further improving the repellent effect of the bird repellent device.

[0049] In the embodiments of the present invention, the fixed connection may be achieved by welding. The detachable connection may be achieved by using a screw and nut. That is, two parts that need to be detachably connected may have a screw on one part and a nut on the other part, and the detachable connection may be achieved by engaging the screw and nut. Alternatively, the detachable connection may be achieved by an interference fit. Alternatively, the detachable connection may be achieved by using a buckle connection. That is, one of the two parts that need to be detachably connected is provided with a buckle, and the other is provided with a structure that can be fastened by the buckle.

[0050] In an embodiment of the present invention, the mounting base 500 is used to mount the bird repellent device, and four holes are drilled in the mounting base 500, and by passing screws through the four holes, it is possible to mount the bird repellent device in places where bird repellent is required, such as roofs where bird repellent is required.

[0051] Optionally, there is a hole in the middle of the reflective structure 100, and a fixing protrusion 231 is provided on the side of the triangular metal frame 230 away from the support arm 220, i.e., the side where the reflective structure 100 is fixed, so that the protrusion 231 can be tightly fitted into the hole, thereby fixing the reflective structure 100 to the triangular metal frame 230.

[0052] Optionally, a male thread structure is provided on the protrusion 231, and the hole of the reflecting structure 100 is engaged with the protrusion 231, and a fixing bolt 232 having a female thread structure provided in a screw hole is used to engage the female thread structure on the inner wall of the screw hole with the male thread structure on the protrusion 231, thereby fixing the reflecting structure 100 to the triangular metal frame 230.

[0053] In an embodiment of the present invention, a solar energy structure may be provided in front of the top reflective structure 109 installed on the top rod 215 of the bird repellent device. The solar energy structure can absorb solar energy, convert the solar energy into electrical energy, and supply the electrical energy to the power structure (inflator) via a power line. In addition, the bird repellent device may be installed near an outdoor air conditioning unit, and the thermal energy generated by the compressor of the outdoor air conditioning unit may be converted into electrical energy to supply the bird repellent device, thereby realizing the recycling of electrical energy from air conditioning.

[0054] In this embodiment of the present invention, the top reflective structure 109 also serves to shield against rainwater. That is, the top reflective structure 109 is installed above the power structure 400 to prevent rainwater from entering the power structure 400 and prevent leakage caused by rain. Optionally, a protection box may be installed outside the power structure 400 to prevent leakage.

[0055] In an embodiment of the present invention, the bird repellent device further includes an ultrasonic structure, and the ultrasonic structure is installed inside the protective box to detect birds. When a bird is detected, a detection signal is sent to the control device, which then automatically controls a solar power generator or a DC or AC commercial power source to provide power to the inflator, and controls the bird repellent device to cause the reflective structure 100 to vibrate in a series, thereby repelling the birds. This allows birds to be repelled using multiple energy channels, and the bird repellent device can achieve good repelling effects under various conditions.

[0056] As described above, this embodiment of the present invention provides a bird repellent device in which the power structure supplies power to the telescopic rod once, extending the telescopic rod and compressing the first and second springs. After the power supply is stopped, the first and second springs recoil, causing the telescopic rod to vibrate, which in turn activates the vibration of the reflective structure, allowing the reflective structure to dynamically reflect light and repel nearby birds. Furthermore, the vibration of the control line 300 increases the frequency of the vibration of the reflective structure, improving the ability, frequency, and duration of the reflective structure to dynamically reflect light, thereby further improving the bird-repelling effect. By providing power only once and extending the vibration duration of the reflective structure, energy is saved and the bird-repelling effect is improved. Furthermore, the bird repellent device can use multiple energy channels to repel birds, including solar energy, thermal energy from air conditioning, wind energy from outdoor air conditioners, and electrical energy from AC commercial power sources, allowing the bird repellent device to provide good repelling effect under various conditions.
