Description

Technical Field

[0001] The invention relates to the field of signboards, in particular to an airport bird-repelling signboard based on an infrared detection module. Background Art

[0002] The infrared detection-based bird repellent sign is an innovative solution designed to effectively reduce bird activity near airports, thereby reducing the risk of bird strikes. Combining infrared detection technology with a bird repellent strategy, this sign is highly practical and effective.

[0003] In the existing technology, the infrared detection module is the core part of this sign. It uses the characteristics of infrared rays to detect birds by receiving and analyzing the infrared radiation emitted by the target object. This detection method is highly sensitive and accurate and can effectively detect the presence of birds under various environmental conditions. When the infrared detection module detects that a bird is approaching the sign, it will immediately trigger the bird-repelling mechanism, which may include emitting sound waves, flashes or other forms of stimulation of a specific frequency to drive away the birds. These stimuli are uncomfortable and threatening to the birds, so they will quickly leave the area; however, the traditional method is to fix the infrared detection module directly on the sign, which has the problem of limited detection angle of the infrared detection module, which affects the bird-repelling effect of the sign.

A plurality of steel balls 32 are provided inside the steel ball groove 31, and the steel ball groove 31 is blocked by a cover plate 34. A light strip 36 is fixed on the surface of the cover plate 34; the miniature infrared detection sensor 11 is embedded in the extension frame 7, and after the extension arm 3 is extended from the extension arm 3, the miniature infrared detection sensor 11 on the extension frame 7 is on the outside of the sign 1, so as to detect birds around the sign 1, and the detection angle is better; it further solves the problem of limited detection angle of the infrared detection module directly fixed on the existing sign; the infrared detection module can be extended to the outside of the sign to expand the detection angle of the infrared detection module.

[0039] Example 2

[0040] Refer to the attached Figure 11 and Figure 18 On the basis of embodiment 1, the extension arm 3 received in the side groove 2 is limited, the height of the side groove 2 is less than the height of the sign board 1, the side groove 2 passes through the top surface of the sign board 1, and a limiting axis 5 is fixed between the two parallel side walls of the side groove 2. The limiting axis 5 passes through the bottom end of the extension arm 3. After the extension arm 3 receives the side groove 2, a reflective warning tape 4 is fixed on the side of the extension arm 3 facing the outside of the side groove 2; a receiving groove 6 is provided on both sides of the extension arm 3, and the length of the long side of the receiving groove 6 is less than the length of the long side of the extension arm 3. The extension frame 7 is a "J"-shaped plate structure, and the extension frame 7 is slidably connected It is connected to the storage slot 6, and a rubber support plate 8 is fixed in the slot body of the extension frame 7. One side of the rubber support plate 8 is fixed to the surface of the storage slot 6. Baffles 9 are fixed on the two parallel side walls of the storage slot 6. The baffles 9 limit the extension frame 7. In the initial state, the rubber support plate 8 supports one end of the extension frame 7 and pops out of the storage slot 6; a card slot 12 is provided on the two parallel side walls of the side slot 2. After the extension arm 3 is pushed into the side slot 2, the extension frame 7 is inserted into the card slot 12, and two pick-up grooves 13 are provided on both sides of the mark plate 1, and the pick-up groove 13 is connected to the card slot 12.

[0041] The reason why pop-up extension frames 7 are inserted on both sides of the extension arm 3 is that after the extension arm 3 extends from the side groove 2 and the extension frame 7 pops out from the storage groove 6, the two sets of micro-infrared detection sensors 11 on the surface of the extension frame 7 can meet the needs of bird detection on both sides of the sign 1, avoiding the situation where the detection field of the micro-infrared detection sensor 11 is blocked by the side wall of the sign 1 after the micro-infrared detection sensor 11 is directly fixed to the extension arm 3; the reason why a card slot 12 is provided on the side wall of the side groove 2 is that after the extension arm 3 is pushed into the side groove 2, the pop-up extension frame 7 is inserted into the card slot 12, forming a limit plug for the extension arm 3 inside the side groove 2, that is, the extension frame 7 is used for two purposes When the extension arm 3 extends out of the side groove 2, the extension frame 7 acts as an extension plate to expand the detection field of view of the micro infrared detection sensor 11. When the extension arm 3 extends into the side groove 2, the extension frame 7 acts as an insertion plate to limit the extension arm 3 inside the side groove 2. It should be noted that when the sign 1 is in transit or idle, the extension arm 3 is pushed into the side groove 2. This not only saves storage space, but also the micro infrared detection sensor 11 is protected between the side groove 2 and the extension arm 3. It further solves the problem of limited detection angle of view of the infrared detection module directly fixed on the existing sign. The infrared detection module can be extended to the outside of the sign to expand the detection angle of the infrared detection module.

[0042] Example 3

[0043] Refer to the attached Figures 12 to 14On the basis of embodiment 2, in order to limit the extension arm 3 after extending from the side groove 2, a reserved groove 10 is provided on the surface of the extension frame 7, and the long side length of the reserved groove 10 is equal to the long side length of the extension frame 7. A plurality of miniature infrared detection sensors 11 are fixed inside the reserved groove 10. After the extension arm 3 is pulled out from the side groove 2, the extension arm 3 is overlapped on the pad 17. The pad 17 is a right-angled trapezoidal block, the inclined surface of the pad 17 faces upward, and the pad 17 is fixed to the bottom surface of the side groove 2; two parallel side walls of the side groove 2 are provided with a notch 14, and a rubber clamp 15 is fixed inside the notch 14. One end of the rubber clamp 15 is fixed to a stopper 16, and the stopper 16 is movably inserted in the notch 14. In the initial state, the rubber clamp 15 extends out of the notch 14 at one end of the support stopper 16. After the extension arm 3 is overlapped on the pad 17, the extension arm 3 is clamped between the pad 17 and the stopper 16.

[0044] When the miniature infrared detection sensor 11 is needed, two fingers are respectively inserted into the two picking grooves 13 on one side of the sign 1, and then the two fingers are closed, that is, the two fingers squeeze the two extension frames 7 into the corresponding storage grooves 6. At this time, the rubber support plate 8 is compressed to produce elastic deformation, and the extension arm 3 is pulled to rotate downward with the limit shaft 5 as the central axis. If the stopper 16 blocks the extension arm 3, the two fingers push the two stoppers 16 toward the corresponding notch 14. At this time, the stopper 16 squeezes the rubber clamping block 15 to produce elastic deformation until the extension arm 3 is pulled out of the side groove 2 and overlaps On the pad 17, the rubber clamp 15 rebounds and pushes one end of the stop block 16 to pop out and block on the extension arm 3. At this time, the extension arm 3 is clamped between the pad 17 and the stop block 16 and will not swing, and the extension frame 7 is pushed out of the storage slot 6 by the elastically rebounding rubber support plate 8, and the blocking bar 9 blocks one end of the extension frame 7 to prevent the extension frame 7 from completely detaching from the storage slot 6; this further solves the problem of limited detection angle of view of the infrared detection module directly fixed on the existing signboard; the infrared detection module can be extended to the outside of the signboard to expand the detection angle of the infrared detection module.

[0045] Example 4

[0046] Refer to the attached Figures 5 to 10 as well as Figures 15 to 17On the basis of embodiment 3, in order to achieve the purpose of dispersing the birds that land on the sign board 1, the mounting groove 18 is a "convex" shaped circular groove, and the sealing plate 24 is inserted into the notch at one end of the mounting groove 18 and rests on the stepped surface of the mounting groove 18. The surface of the sealing plate 24 is screwed with a plurality of connecting screws 25, and the connecting screws 25 pass through the sealing plate 24 and are screwed on the stepped surface of the mounting groove 18. A servo motor 26 is fixed on the surface of the sealing plate 24, and the rotating shaft of the servo motor 26 passes through the sealing plate 24 and is fixed to the surface of the rotating handle 27; the limit stop bar 19 is a semi-cylindrical structure, and a plurality of limit stop bars 19 are provided. The plurality of limit stop bars 19 are arranged and distributed along the circumferential surface of the mounting groove 18, and two of the limit stop bars 19 symmetrically distributed about the central axis of the mounting groove 18 are provided with an introduction hole 20 on the surface. One end of the introduction hole 20 is an arc-shaped curved surface, and the other end of the introduction hole 20 is provided with a second card slot 21, which is a spherical groove, and the interior of the card slot 21 is plugged with a rubber The rubber clamp head 22 is sleeved and fixed on one end of the guide rod 23, and the other end of the guide rod 23 is fixed to the surface of the sealing plate 24; both ends of the rotating handle 27 are provided with an embedding groove 28, and the knocking handle 29 corresponds to the embedding groove 28 one by one, and the knocking handle 29 is movably inserted into the embedding groove 28, and a spring 30 is fixed between the knocking handle 29 and the embedding groove 28. The spring 30 is in the initial state to support one end of the knocking handle 29 and extend out of the embedding groove 28; the marking plate 1 The top surface is provided with an assembling groove 33, and there are two assembling grooves 33. The assembling groove 33 is connected to the steel ball groove 31. The two assembling grooves 33 are symmetrically distributed about the steel ball groove 31. The depth of the assembling groove 33 is smaller than the depth of the steel ball groove 31. The cover plate 34 is a "Z"-shaped plate structure. The two ends of the cover plate 34 are respectively inserted into the two assembling grooves 33. Both ends of the cover plate 34 are screwed with a connecting screw 2 35. The connecting screw 2 35 passes through the sealing plate 24 and is screwed to the surface of the assembling groove 33.

[0047] After the switch of the connecting screw 25 is triggered, the connecting screw 25 drives the rotating handle 27 to rotate inside the mounting groove 18. During this process, the knocking handle 29 at the end of the rotating handle 27 passes through multiple limit bars 19 in sequence. When the knocking handle 29 is on one side of the limit bar 19, the spring 30 is in the initial state. At this time, the knocking handle 29 is supported by the spring 30 to extend out of a part of the embedded groove 28, and the extended end of the knocking handle 29 is against the side wall of the mounting groove 18. When the knocking handle 29 contacts the limit bar 19 and the rotating handle 27 continues to rotate, the limit bar 19 will knock the knocking handle 29. The spring 30 is compressed and elastically deformed until the striking handle 29 passes over the limit stop 19. The spring 30 rebounds and pushes the striking handle 29 out of the striking groove 28 to strike the side wall of the mounting groove 18. In this way, during the rotation of the rotating handle 27, the striking handle 29 strikes repeatedly. The vibration generated by the striking will scatter the birds that fall on the sign 1, and the vibration generated by the striking will drive the steel ball 32 to bump in the steel ball groove 31. Since the steel ball 32 is closer to the top surface of the sign 1, the bumping steel ball 32 has a certain auxiliary effect on dispersing the birds that fall on the top surface of the sign 1.

[0048] The reason for providing the introduction hole 20 and the second card slot 21 on the surface of the two limit stop bars 19 is to pre-fix the sealing plate 24 at the notch of the mounting groove 18, that is, after the sealing plate 24 is pushed into the notch of the mounting groove 18, the introduction rod 23 is inserted into the introduction hole 20, and the rubber clamp 22 is inserted into the second card slot 21. At this time, even if the connecting screw 25 is not fixed, the sealing plate 24 will not fall off. In order to strengthen the installation of the sealing plate 24, the sealing plate 24 can be fixed on the stepped surface of the mounting groove 18 by connecting the screw 25; and a flashing light strip 36 is selected, which can also have a dispersing effect on birds after turning on the light strip 36; further solves the problem of limited detection angle of the infrared detection module directly fixed on the existing signboard; the infrared detection module can be extended to the outside of the signboard to achieve the extension of the detection angle of the infrared detection module.

[0049] Example 5

[0050] Based on the fourth embodiment, a method for using an airport bird-repellent sign based on an infrared detection module is proposed, including the following steps:

[0051] Step 1: There are pop-up extension frames 7 on both sides of the extension arm 3. This is so that after the extension arm 3 extends from the side groove 2 and the extension frame 7 pops out from the storage groove 6, the two sets of micro infrared detection sensors 11 on the surface of the extension frame 7 can detect birds on both sides of the sign 1, avoiding the situation where the micro infrared detection sensor 11 is directly fixed to the extension arm 3 and the detection field of the micro infrared detection sensor 11 is blocked by the side wall of the sign 1; the reason why the side wall of the side groove 2 is provided with a card slot 12 is so that after the extension arm 3 is pushed into the side groove 2, the pop-up extension frame 7 Inserted into the card slot 12, it constitutes a limiting plug plate for the extension arm 3 inside the side groove 2, that is, the extension frame 7 serves two purposes: when the extension arm 3 extends out of the side groove 2, the extension frame 7 acts as an extension plate to expand the detection field of view of the miniature infrared detection sensor 11; when the extension arm 3 extends into the side groove 2, the extension frame 7 acts as a plug plate to limit the extension arm 3 inside the side groove 2; it should be noted that when the sign 1 is transported or idle, the extension arm 3 is pushed into the side groove 2, which not only saves storage space, but also protects the miniature infrared detection sensor 11 between the side groove 2 and the extension arm 3;

[0052] Step 2: When using the miniature infrared detection sensor 11, two fingers are respectively inserted into the two picking grooves 13 on one side of the sign board 1, and then the two fingers are closed, that is, the two fingers squeeze the two extension frames 7 into the corresponding storage grooves 6. At this time, the rubber support plate 8 is pressurized to produce elastic deformation, and the extension arm 3 is pulled downward with the limit shaft 5 as the central axis. If the stopper 16 blocks the extension arm 3, the two fingers push the two stops 16 toward the corresponding notched groove 14. At this time, the stopper 16 squeezes the rubber clamping block 15 to produce elastic deformation until the extension arm 3 is pulled out of the side groove 2 and overlaps the pad 17. The rubber clamping block 15 rebounds and pushes one end of the stopper 16 to pop out and block the extension arm 3. At this time, the extension arm 3 is clamped between the pad 17 and the stopper 16 and will not swing, and the extension frame 7 is pushed out of the storage groove 6 by the elastically rebounding rubber support plate 8, and the blocking bar 9 blocks one end of the extension frame 7 to prevent the extension frame 7 from completely detaching from the storage groove 6.

[0053] Step 3: After the switch of the connecting screw 25 is triggered, the connecting screw 25 drives the rotating handle 27 to rotate inside the mounting groove 18. During this process, the knocking handle 29 at the end of the rotating handle 27 passes through multiple limit bars 19 in sequence. When the knocking handle 29 is on one side of the limit bar 19, the spring 30 is in the initial state. At this time, the knocking handle 29 is supported by the spring 30 to extend out of a part of the embedded groove 28, and the extended end of the knocking handle 29 is against the side wall of the mounting groove 18. When the knocking handle 29 contacts the limit bar 19 and the rotating handle 27 continues to rotate, the limit bar 19 will knock the knocking handle. 29 is pushed into the interior of the embedding groove 28. At this time, the spring 30 is compressed and elastically deformed until the knocking handle 29 passes over the limit stop bar 19. The spring 30 rebounds and pushes the knocking handle 29 out of the embedding groove 28 to knock the side wall of the installation groove 18. In this way, during the rotation of the rotating handle 27, the knocking handle 29 repeatedly knocks, and the vibration generated by the knocking will scatter the birds landing on the sign 1. The vibration generated by the knocking drives the steel ball 32 to bump in the steel ball groove 31. Since the steel ball 32 is closer to the top surface of the sign 1, the bumping steel ball 32 has a certain auxiliary effect on dispersing the birds landing on the top surface of the sign 1.

[0054] Step 4: An introduction hole 20 and a second card slot 21 are opened on the surface of the two limit stop bars 19 to pre-fix the closing plate 24 at the notch of the mounting groove 18, that is, after the closing plate 24 is pushed into the notch of the mounting groove 18, the introduction rod 23 is inserted into the introduction hole 20, and the rubber clamp 22 is inserted into the second card slot 21. At this time, even if the connecting screw 1 25 is not fixed, the closing plate 24 will not fall off. In order to strengthen the installation of the closing plate 24, the closing plate 24 can be fixed on the stepped surface of the mounting groove 18 by connecting the screw 1 25; and a flashing light strip 36 is selected, which can also have a bird-repelling effect after turning on the light strip 36.

[0055] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
