[0014] Compared to the prior art, the embodiments of the present invention have the following beneficial effects. Embodiments of the present invention further provide a bird repellent device comprising a reflective structure, a support structure, control lines, a power structure, and a mounting base, wherein the support structure comprises an axial support rack, a support arm, and a triangular metal frame, the triangular metal frame being a single triangular frame surrounded by metal wires, the outer side of one corner of the triangular metal frame being fixed to the axial support rack at one end of the support arm, a through coil installed in the triangular metal frame, the reflective structure being disc-shaped, the front and back surfaces of the reflective structure being coated with a reflective material capable of reflecting light rays, the back surface of the reflective structure being detachably connected to the triangular metal frame, the axial support rack comprising a bottom rod, a first spring, a telescopic rod, a top rod, and a second spring, the telescopic rod is The structure is extendable, with one end of the support arm detachably connected to the extendable rod, one end of the bottom rod detachably connected to the mounting base, the other end of the bottom rod away from the mounting base fixedly connected to one end of the first spring, the other end of the first spring away from the bottom rod detachably connected to one end of the extendable rod, the other end of the extendable rod away from the first spring detachably connected to one end of the second spring, the other end of the second spring away from the extendable rod fixedly connected to the top rod, the power structure is installed on the extendable rod and used to provide extension and retraction power to the extendable rod, one end of the control wire is fixed to the top rod and the other end is fixed to the bottom rod after passing through the through coil and the control wire maintains tension.

Both power sources drive the vibration of the reflective structure, reinforcing its vibration and improving the ability, frequency, and duration of the reflective structure to reflect light rays, thus enhancing its bird-driving effect. Compared to conventional technology, which requires continuous power to vibrate the reflective structure, the bird repellent device provided by the embodiment of the present invention saves energy by providing power only once, extending the vibration time of the reflective structure, saving energy, and improving the bird-repelling effect. [Brief explanation of the drawing]

[0016] [Figure 1] This is a schematic diagram of a bird repellent device provided by an embodiment of the present invention. [Modes for carrying out the invention]

[0017] The present invention will be described in detail below with reference to the drawings. Studies have shown that birds are afraid of dynamic light rays, and that dynamic reflected light rays can be used to startle birds and achieve repellency. Therefore, this application provides a bird repellent device. Specifically, refer to the following examples.

[0018] Examples Embodiments of the present invention provide a bird repellent device for driving away birds. As shown in FIG. 1, the bird repellent device includes a reflection structure 100, a support structure 200, a control wire 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 wires. One outer side of one corner of the triangular metal frame 230 is fixed to one end of the axial support rack 210 of the support arm 220 away from it. A through coil is installed on the triangular metal frame 230. The through coil is a single circle and is welded to the triangular metal frame 230.

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

[0022] The reflection structure 100 is disc-shaped, and a reflective material coating layer capable of reflecting light rays is installed on both the front and back surfaces of the reflection structure 100. The back surface of the reflection structure 100 is detachably connected to the triangular metal frame 230. In an embodiment of the present invention, the detachable connection means between the back surface of the reflection structure 100 and the triangular metal frame 230 may be a buckle connection means. That is, an engaging groove is provided on the back surface of the reflection structure 100, the triangular metal frame 230 is engaged into the engaging groove, and the triangular metal frame 230 and the engaging groove are in interference fit. The detachable connection means between the back surface of the reflection structure 100 and the triangular metal frame 230 may be that a buckle is installed on the back surface of the reflection structure 100, and the fixation between the triangular metal frame 230 and the reflection structure 100 is realized by the engagement between the buckle and the triangular metal frame 230.

[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 that is not connected to the mounting base 500 is fixedly connected to one end of the first spring 212.

[0026] One end of the first spring 212, away from the bottom rod 211, is detachably connected to one end of the telescopic rod 213. The other end of the telescopic rod 213, away from the first spring 212, is detachably connected to one end of the second spring 214. The other end of the second spring 214, away 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 the telescopic rod 213 with power to extend and retract.

[0028] In embodiments of the present invention, the control wire 300 may be a thin metal wire such as a steel wire, iron wire, stainless steel wire, or aluminum wire. Alternatively, the control wire 300 may be a flexible wire such as a rubber wire.

[0029] By adopting the above technical proposal, each time the power structure 400 supplies power to the telescopic rod 213 and extends the telescopic rod 213, compressing the first spring 212 and the second spring 214, after the power supply ends, the repulsion process of the first spring 212 and the second spring 214 causes vibration of the telescopic rod 213, which in turn causes vibration of the reflective structure 100, so that the reflective structure 100 dynamically reflects light rays and can drive away nearby birds. Furthermore, one end of the control wire 300 is fixed to the top rod 215, and the other end, after passing through the through-coil, is fixed to the bottom rod 211. The control wire 300 maintains a state of tension, causing vibration of the control wire 300 during the repulsion process of the first spring 212 and the second spring 214. As the control wire 300 becomes taut, it comes into contact with the triangular metal frame 230 (and the through-coil), causing the control wire 300 to vibrate and further increasing the vibration frequency of the reflective structure 100. Both forces drive the vibration of the reflective structure 100, reinforcing its vibration and improving the ability, frequency, and duration of the reflective structure 100 to reflect light rays, thereby improving its bird-repelling effect. Compared to conventional technology, which requires continuous power to vibrate the reflective structure 100, the bird repellent device provided by the embodiment of the present invention saves energy, meaning that power is supplied only once, extending the vibration time of the reflective structure, saving energy, and improving the bird-repelling effect.

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

[0031] One end of the first spring 212, which is separated from the bottom rod 211, is detachably connected to the first end of the inner rod 2131.

[0032] The outer rod 2132 is a single hollow rod having a hollow cavity along its axial direction, and the second end of the inner rod 2131 extends into the hollow cavity, thereby allowing the inner rod 2131 to extend and retract along the axial direction of the outer rod 2132. The second end is the other end of the inner rod 2131 that is separated 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 installed in the hollow cavity separated from the first end and is detachably connected to the second end.

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

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

[0037] A small hole is provided in the outer rod 2132, and a power line passes through this small hole, with one end connected to the inflator and the other end connected to the power supply. Power is supplied to the inflator by a single power line, and the inflator 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 terminated, the rebound process of the first spring 212 and the second spring 214 compresses the airbag and releases the airbag, and the rebound process of the first spring 212 and the second spring 214 causes vibration of the telescopic rod 213. This causes the reflective structure 100 to vibrate in conjunction with the reflective structure 100, allowing the reflective structure 100 to dynamically reflect reflected light rays, which can startle and drive away nearby birds.

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

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

[0040] Selectively, the reflective structure 100 is a plurality of units, the support arms 220 are a plurality of units, each reflective structure 100 is mounted on one support arm 220, and the reflective structure 100 is connected to the support arms 220 by a triangular metal frame 230.

[0041] Selectively, there are eight support arms 220, which are the first support arm 221, the second support arm 222, the third support arm 223, the fourth support arm 224, the fifth support arm, the sixth support arm, the seventh support arm, and the eighth support arm.

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

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

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

[0045] Selectively, the support arm 220 is installed so as to form an acute angle with the telescopic rod 213, or the support arm 220 is installed so as to be perpendicular to the telescopic rod 213.

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

[0047] In Figure 1, the fifth support arm, the sixth support arm, the seventh support arm, and the eighth support arm are shielded by the fifth reflective structure 105 and the sixth reflective structure 106, respectively, and cannot be shown. 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 identical to those 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 proposal, the plane on which each reflective structure 100 is located is parallel to the telescopic rod 213. In the first direction, the light ray may be reflected by the front surface of each individual reflective structure 100, or by the back surface of the reflective structure 100. Furthermore, an incident light ray at an acute angle is reflected by the back surface of the third reflective structure 103 to the back surface of the first reflective structure 101, then reflected via the back surface of the first reflective structure 101 to the back surface of the fourth reflective structure 104, and further reflected via the back surface of the fourth reflective structure 104 to the back surface of the second reflective structure 102, and finally reflected downwards through the second reflective structure 102 to the bird repellent device. Similarly, the light rays may be reflected by the back surface of the seventh reflective structure 107 to the back surface of the fifth reflective structure 105, and then reflected via the back surface of the fifth reflective structure 105 to the back surface of the eighth reflective structure 108, and further reflected via the back surface of the eighth reflective structure 108 to the back surface of the sixth reflective structure 106, and finally reflected downward through the sixth reflective structure 106. Adding one reflective structure 100 installed on the top rod 215 of the bird repellent device, the bird repellent device can reflect light rays in all directions, that is, it can reflect light rays in all directions and drive birds away in all directions. This further improves the repellent effect of the bird repellent device.

[0049] In embodiments of the present invention, the fixed connection may be a welding method. Removable connection can be achieved by a screw and nut method. That is, in two parts that need to be removablely connected, one part is provided with a screw and the other part is provided with a nut, and a removable connection can be achieved by the engagement of the screw and nut. Alternatively, a removable connection can be achieved by a crimp-fit ​​method. Alternatively, a removable connection can be achieved by a buckle connection method, that is, in two members that require a removable connection, one is provided with a buckle and the other is provided with a structure that can be fixed by the buckle.

[0050] In an embodiment of the present invention, the mounting base 500 is used to attach a bird repellent device. Four holes are made in the mounting base 500, and by passing screws through the four holes, it is possible to attach the bird repellent device to a location where bird repellent is needed, such as a roof.

[0051] Selectively, there is a hole in the middle of the reflective structure 100, and a fixing projection 231 is installed on the side of the triangular metal frame 230 away from the support arm 220, i.e., the side to which the reflective structure 100 is fixed, and this projection 231 can be tightened into the hole. This makes it possible to fix the reflective structure 100 to the triangular metal frame 230.

[0052] Selectively, a male threaded structure is installed on the projection 231, and the hole in the reflective structure 100 is engaged with the projection 231. By using a single fixing bolt 232, in which a female threaded structure is installed in one of the screw holes, the female threaded structure on the inner wall of the screw hole engages with the male threaded structure on the projection 231, thereby enabling the reflective structure 100 to be fixed to the triangular metal frame 230.

[0053] In an embodiment of the present invention, a solar energy structure may be provided on the 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 it into electrical energy, and supply electrical energy to the power structure (inflator) via a power line. Furthermore, if the bird repellent device is installed near the air conditioning unit, the thermal energy generated by the air conditioning unit's compressor can be converted into electrical energy, thereby supplying electrical energy to the bird repellent device and enabling the recycling of electrical energy from the air conditioning system.

[0054] In the embodiment of the present invention, the top reflective structure 109 also serves to shield against rainwater. That is, by installing the top reflective structure 109 above the power structure 400, it is possible to prevent rainwater from entering the power structure 400 and prevent electrical leakage due to rain.Optionally, electrical leakage may be prevented by installing a protective box outside the power structure 400.

[0055] In an embodiment of the present invention, the bird repellent device further includes an ultrasonic structure, the ultrasonic structure for detecting birds being installed inside a protective box. When a bird is detected, a detection signal is transmitted to a control device, which automatically controls a solar power generation device or a DC or AC commercial power supply to provide power to the inflator, thereby controlling the bird repellent device to perform a series of vibrations of the reflective structure 100, and thus driving away the birds. Bird repellent can be achieved using multiple energy channels, and the bird repellent device can exhibit a good repellent effect under various conditions.

[0056] As described above, the embodiments of the present invention provide 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. Each time the power supply ends, the repulsion process of the first and second springs causes vibration of the telescopic rod, which in turn causes vibration of the reflective structure. This reflective structure dynamically reflects light rays, driving away nearby birds. Furthermore, the vibration of the control line 300 increases the frequency of vibration of the reflective structure, improving the ability, frequency, and duration of the reflective structure to dynamically reflect light rays, further enhancing the bird repellent effect. By supplying power only once and extending the vibration time of the reflective structure, energy is saved while improving the bird repellent effect. In addition, by utilizing solar energy, thermal energy from air conditioning heat dissipation, wind energy provided by air conditioners, and electrical energy provided by AC commercial power, bird repellent can be performed using multiple energy channels, enabling the bird repellent device to exhibit a good repellent effect under various conditions.
