Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Refer to Figures 1 - 12 , a building intelligent security monitoring device, including a body 1, a photoresistor 2 is embedded on the upper surface of the body 1, an electromagnet 3 is fixedly installed on the back surface of the body 1, the electromagnet 3 is electrically connected to the photoresistor 2 through a wire, a placement plate is fixedly installed on the back surface of the body 1, a first mounting rod 4 is vertically and fixedly installed on the upper surface of the placement plate, a vertical groove is opened at the top end of the first mounting rod 4, a vertical rod 5 is hermetically and slidably inserted in the vertical groove, a ventilation port 6 is opened on the surface of the first mounting rod 4, a first telescopic spring 7 is fixedly installed at the bottom end of the vertical rod 5, the bottom end of the first telescopic spring 7 is fixedly connected to the bottom of the vertical groove, and a magnet 8 is fixedly installed at the top end of the vertical rod 5.

[0020] The side wall of the body 1 is horizontally slidably provided with an L-shaped driving strip 9 through a sliding member. The sliding member includes a slider 11 fixedly installed on the surface of the driving strip 9. A chute 12 is opened on the side wall of the body 1. The slider 11 is slidably arranged in the chute 12. The longitudinal section of the chute 12 is a right trapezoid, and the bottom surface of the chute 12 is inclined to prevent impurities from accumulating in the chute 12. The surface of the driving strip 9 is in sliding contact with the upper surface of the body 1. Mounting shafts are fixedly installed on the side walls of the driving strip 9 and the magnet 8, and a hinged rod 10 is hinged on the two mounting shafts.

[0021] When the light received by the photoresistor 2 is relatively strong, its resistance is small, so the magnetism of the electromagnet 3 is relatively strong. When the light received by the photoresistor 2 is relatively weak, its resistance is large, so the magnetism of the electromagnet 3 is relatively weak. When a bird stays on the upper surface of the body 1, it will block the light received by the photoresistor 2, so the light received by the photoresistor 2 at this time will become weaker, the magnetism of the electromagnet 3 will become weaker, and the magnetic attraction force received by the magnetic block 8 will also become weaker. Therefore, the magnetic block 8 will drive the vertical rod 5 to move downward in the first mounting rod 4 under the elastic potential energy of the first telescopic spring 7. Under the action of the hinge rod 10, the driving strip 9 will move horizontally, thus achieving the effect of bird repelling.

[0022] When the driving strip 9 moves, it will slide into contact with the surface of the photoresistor 2, so that the dust or impurities attached to the surface of the photoresistor 2 can be scraped off, achieving the cleaning effect and preventing the attached dust and impurities from affecting the light reception of the photoresistor 2.

[0023] A sound generating component is provided on the side wall of the body 1. The sound generating component is used to emit sound to repel birds when the driving strip 9 moves. The sound generating component includes three mounting blocks 13 fixedly installed on the side wall of the body 1 at equal intervals, three piston rods 14, and three whistles 15. A socket is opened on the upper surface of the mounting block 13. Each piston rod 14 is slidably and sealingly inserted into each socket. A U-shaped air pipe 16 is fixedly installed at the bottom end of the mounting block 13. Each whistle 15 is fixedly installed at the end of each air pipe 16. A force receiving block 17 is fixedly installed at the top end of the piston rod 14. A pressing block 18 is fixedly installed at the bottom end of the driving strip 9. The longitudinal sections of the force receiving block 17 and the pressing block 18 are both isosceles triangles, and the inclined surfaces of the force receiving block 17 and the pressing block 18 are arranged face to face. A second telescopic spring 19 is provided in the socket. The two ends of the second telescopic spring 19 are fixedly connected to the top end of the piston rod 14 and the bottom wall of the socket respectively.

[0024] When the driving strip 9 moves, the pressing block 18 will also move together. During the movement of the pressing block 18, it will intermittently slide into contact with the inclined surfaces of multiple force receiving blocks 17. The piston rod 14 will move downward under the action of the inclined surface pressing, and then quickly move upward under the elastic potential energy of the second telescopic spring 19. When the piston rod 14 moves downward, the volume of the space between the bottom end of the piston rod 14 and the bottom wall of the socket will become smaller, the pressure will increase, and the gas in the socket will enter the whistle 15 from the air pipe 16 and then be ejected from the whistle 15, and the whistle 15 will emit sound, thus enhancing the effect of bird repelling.

[0025] A circular opening is provided on the side wall of the body 1. A rotating ring 20 is rotatably installed in the circular opening. A dust-proof net 21 is fixedly embedded in the rotating ring 20. A knocking assembly is provided on the side wall of the body 1. The knocking assembly is used for intermittently knocking the dust-proof net 21. The knocking assembly includes a moving plate 22 fixedly connected to the side wall of the body 1 through a first spring rod 43 and two knocking balls 23. Both knocking balls 23 are fixedly connected to the moving plate 22 through connecting rods, and the knocking balls 23 are in contact with the surface of the dust-proof net 21. The first spring rod 43 is controlled to expand and contract through a pressing assembly. The pressing assembly includes a cross plate 24 fixedly installed on the side wall of the driving strip 9, a plurality of bumps 25 fixedly installed on the surface of the cross plate 24 at equal intervals, and a triangular block 26 fixedly connected to the moving plate 22 through a connecting rod. The cross section of the bump 25 is a right trapezoid, and the inclined surface of the bump 25 is parallel to the inclined surface of the triangular block 26.

[0026] In the initial state, the two knocking balls 23 will be in contact with the dust-proof net 21 under the elastic potential energy of the first spring rod 43. When the driving strip 9 moves, it will drive the cross plate 24 and a plurality of bumps 25 to move together. The inclined surface of the bump 25 will slide into contact with the inclined surface of the triangular block 26. Under the action of the inclined surface pressing, the first spring rod 43 will stretch, so that the two knocking balls 23 will separate from the dust-proof net 21. Until the triangular block 26 no longer contacts the bump 25, the moving plate 22 will quickly move back to its original position with the two knocking balls 23 under the elastic potential energy of the first spring rod 43. The two knocking balls 23 will collide with the dust-proof net 21, applying an impact force to the dust-proof net 21, causing the dust-proof net 21 to vibrate and shaking off the dust attached to the surface of the dust-proof net 21, avoiding too much attached dust from affecting the air permeability of the dust-proof net 21 and thus affecting the overall heat dissipation effect of the device.

[0027] A ratchet wheel 27 is fixedly installed on the surface of the rotating ring 20. A fixed block is fixedly installed on the side wall of the body 1. The upper surface of the fixed block is fixedly installed with a rectangular block 29 through a second spring rod 28. The bottom end of the rectangular block 29 is rotatably connected through a rotating shaft to a rotating block 30 with a right trapezoidal longitudinal section. A rectangular opening is provided on the upper surface of the rotating block 30. A third spring rod 31 in the shape of an arc centered on the rotating shaft is fixedly installed on the side wall of the rectangular block 29. One end of the third spring rod 31 is fixedly connected to the bottom wall of the rectangular opening. The ratchet wheel 27 is located on the moving path of the rotating block 30. The second spring rod 28 is controlled to contract through a pressing-down component. The pressing-down component includes a plurality of pressing-down rods 32 respectively fixedly installed on the surfaces of a plurality of piston rods 14 and a strip-shaped rod 33 fixedly installed on the side wall of the rectangular block 29. The strip-shaped rod 33 is located below the plurality of pressing-down rods 32.

[0028] When the piston rod 14 moves downward, the lower pressing rod 32 will also press against the strip-shaped rod 33, causing the strip-shaped rod 33 to drive the rectangular block 29 and the rotating block 30 to move downward together. The second spring rod 28 will contract, and the bottom of the rotating block 30 will abut against the tooth part of the ratchet wheel 27 and push the ratchet wheel 27 to drive the rotating ring 20 and the dust-proof net 21 to rotate counterclockwise. Then when the piston rod 14 moves upward, the lower pressing rod 32 will also quickly move upward under the elastic potential energy of the second spring rod 28. The top inclined surface of the rotating block 30 will contact the gear of the ratchet wheel 27, and the rotating block 30 will rotate due to the blockage of the gear of the ratchet wheel 27. The third spring rod 31 will be stretched at this time, and the ratchet wheel 27 will not rotate. Then when the next piston rod 14 moves downward, the rectangular block 29 and the rotating block 30 will move downward again, and the rotating block 30 will push the ratchet wheel 27 to rotate counterclockwise again. In the process of controlling the knocking ball 23 to intermittently knock on the dust-proof net 21, the dust-proof net 21 can be controlled to rotate unidirectionally, so that the hitting part of the knocking ball 23 on the dust-proof net 21 will be different each time, improving the comprehensiveness of cleaning the dust-proof net 21.

[0029] A through hole is formed at the front end of the machine body 1, and a lens 34 is fixedly embedded in the through hole. Installation grooves 35 are symmetrically formed at the front end of the machine body 1. Slide rods 36 are slidably arranged in both installation grooves 35. A flexible transparent dust-proof film 37 is connected between the two slide rods 36. The inner wall of the transparent dust-proof film 37 is in sliding contact with the mirror surface of the lens 34. The notch of the installation groove 35 is processed with a single-sided arc transition. A scraping strip 38 is fixedly installed at the notch of the installation groove 35. Both scraping strips 38 are in sliding contact with the outer wall of the transparent dust-proof film 37. The two slide rods 36 are controlled to move by a pneumatic pushing component. The pneumatic pushing component includes a second installation rod 40, a cross bar 41 and two pull ropes 42 connected to the first installation rod 4 through a hollow rod 39. The first installation rod 4 and the second installation rod 40 are perpendicular to each other. A horizontal groove communicating with the vertical groove is formed on the surface of the second installation rod 40. The cross bar 41 is horizontally and sealingly slidably inserted in the horizontal groove. One end of the hollow rod 39 covers the ventilation port 6. Through holes communicating with the two installation grooves 35 are respectively formed on both sides of the machine body 1. The two pull ropes 42 are respectively slidably inserted in the two through holes. One ends of the two pull ropes 42 are respectively fixedly connected to the surfaces of the two slide rods 36, and the other ends are respectively fixedly connected to the surface of the driving strip 9 and the end of the cross bar 41.

[0030] The camera mechanism in the monitoring device is located inside the machine body 1 and works by monitoring and shooting through the lens 34. The lens 34 can protect the camera mechanism and prevent it from being directly exposed. The transparent dust-proof film 37 is in sliding contact with the lens 34, which can prevent external dust from directly adhering to the mirror surface of the lens 34. Similar to the tempered film pasted on a mobile phone, it can protect the lens 34.

[0031] When the vertical rod 5 moves downward, the gas in the vertical groove will enter the hollow rod 39 from the ventilation port 6 at this time, and then enter the transverse groove in the second mounting rod 40, and push the cross bar 41 in the second mounting rod 40 to move towards the lens 34. During this process, the driving strip 9 will pull the pull rope 42 connected to itself, so that the transparent dust-proof film 37 moves. During the movement of the transparent dust-proof film 37, its outer surface will contact the scraping strip 38, and the scraping strip 38 can scrape off the dust attached to the surface of the transparent dust-proof film 37, achieving the effect of cleaning the surface of the transparent dust-proof film 37, and avoiding too much attached dust from affecting the imaging effect.

[0032] When the vertical rod 5 moves upward, the cross bar 41 will move away from the lens 34 at this time, thus pulling the pull rope 42 connected to itself and driving the transparent dust-proof film 37 to move back to its original position. At this time, the dust on the surface of the transparent dust-proof film 37 has been cleaned.

[0033] And because during the movement of the transparent dust-proof film 37, its inner wall will always contact the surface of the lens 34, that is, the protection of the transparent dust-proof film 37 for the lens 34 will not disappear due to the movement. The transparent characteristic also makes the transparent dust-proof film 37 not affect the imaging of the device when it moves, and it is through the movement of the transparent dust-proof film 37 to achieve the effect of cleaning the transparent dust-proof film 37. The positions of the two scraping strips 38 will not move, so that when cleaning the transparent dust-proof film 37, there will be no shadow in the imaging picture of the device, and thus there will be no short-term imaging dead angle.

[0034] In the present invention, when a bird stays on the upper surface of the body 1, it will block the photosensitive resistor 2 from receiving light. As a result, the light received by the photosensitive resistor 2 will become weaker at this time, the resistance will become larger, the magnetism of the electromagnet 3 will become weaker, and the magnetic attraction received by the magnetic block 8 will also become weaker. Therefore, the magnetic block 8 will drive the vertical rod 5 to move downward in the first mounting rod 4 under the elastic potential energy of the first telescopic spring 7. Under the action of the hinge rod 10, the driving strip 9 will move horizontally, thus achieving the effect of bird repelling. And when the driving strip 9 moves, it will slide and contact the surface of the photosensitive resistor 2, so that the dust or impurities attached to the surface of the photosensitive resistor 2 can be scraped off, achieving the cleaning effect, and avoiding the attached dust and impurities from affecting the photosensitive resistor 2's reception of light. And the moving components will also make a sound during the movement of the driving strip 9, enhancing the bird repelling effect.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
