Description

Technical Field

[0001] This invention is a security video surveillance device, belonging to the field of security technology. Background Technology

[0002] Security and protection, or safety and prevention, is a protective technology system that uses prevention as a means and safety as its core objective. Currently, video surveillance devices are the core monitoring equipment in the security and protection field. These devices can convert optical images in the visible to near-infrared spectral range into video electrical signals through image sensors, thereby enabling real-time scene acquisition and monitoring.

[0003] Existing video surveillance equipment mainly consists of a mounting base and camera components. The conventional installation method involves fixing the base to a pre-set monitoring point, keeping the camera's viewing angle fixed. This fixed structure has a limited monitoring range and easily creates blind spots, significantly reducing the overall security effect and quality. To address the blind spot problem in fixed surveillance, existing technologies generally incorporate an automatic rotation drive module, which rotates the camera component to monitor from multiple angles, effectively avoiding blind spots.

[0004] However, this improved structure still has obvious technical drawbacks: when the camera lens rotates with the equipment, the lens lens will face the external airflow, dust and other flowing media, which makes it very easy for dust, water mist and other impurities to adhere to the lens surface, resulting in blurred monitoring images and image distortion, significantly increasing the probability of image acquisition defects, and seriously affecting the long-term stable operation of the equipment and the accuracy of security monitoring.

[0047] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0048] Example 1: As Figures 1-7 As shown, a security video surveillance device is provided, including: a camera 1, a top plate 11 mounted on the upper end of the camera 1, which protects the camera 1 and the circular shell 4, a mounting base 12 mounted on the lower end of the camera 1, which provides a mounting carrier for the camera 1, a top cover 31 mounted on the lower end of the mounting base 12, which provides a mounting carrier for the mounting base 12, and a straight cylinder 3 extending into the top cover 31 and rotatably connected to the lower end of the top cover 31, which provides installation space for components such as the cylinder 34.

[0049] The cylinder 34 is installed inside the straight cylinder 3, and the cylinder 34 provides a mounting carrier for components such as the rotating shaft 35. The rotating shaft 35, whose lower end extends into the cylinder 34, is rotatably connected to the middle of the upper end of the cylinder 34, and the upper end of the rotating shaft 35 is connected to the top end of the top cover 31. The top cover 31 is rotated through the rotating shaft 35. The fixing part of the first driving device is installed on the lower end of the cylinder 34, and the upper end of the output shaft of the first driving device is connected to the rotating shaft 35.

The fixing plate 21 provides a mounting carrier for the mounting plate 2.

[0051] The circular shell 4 is installed on the right end of the camera 1, and the upper end of the circular shell 4 is connected to the top plate 11. The circular shell 4 provides installation space for components such as the annular glass 7. A through hole 41 is formed by the left-facing recess on the upper right end of the circular shell 4, and the left end of the through hole 41 fits against the right end of the camera port of the camera 1. The camera 1 can operate normally through the through hole 41.

[0052] The fixing part of the second drive device located on the right side of the fixed base 12 is installed on the left end of the circular shell 4, and the upper end of the second drive device is connected to the lower end of the camera 1. The inner plate 73 is driven to rotate through the second drive device. The second drive device can be a second motor 8. The inner plate 73 is rotatably connected inside the circular shell 4, and the right end of the output shaft of the second drive device passes through the circular shell 4 and is connected to the inner plate 73. The inner plate 73 provides a mounting carrier for the annular glass 7.

[0053] A ring-shaped glass 7 is installed on the annular end of the inner plate 73, and the annular glass 7 is located inside the circular shell 4. The camera port of the camera 1 is protected by the annular glass 7. Rubber strips 44 are installed on the left and right walls of the lower side of the circular shell 4, and the two rubber strips 44 are respectively attached to the left and right ends of the annular glass 7. The rubber strips 44 are located on the outside of the inner plate 73. The surface of the annular glass 7 is cleaned by using the rubber strips 44.

[0054] A Z-shaped hollow rod 9 is installed on the left end of the mounting box 5, and the left end of the hollow rod 9 is connected to the right end of the top cover 31. A first rod 42 is set on the left end of the circular shell 4, and the left end of the first rod 42 is connected to the right end of the vertical part of the hollow rod 9. A second rod 43 is installed on the left end of the vertical part of the hollow rod 9. The first rod 42, the second rod 43 and the hollow rod 9 work together to strengthen the installation of the circular shell 4. The mounting ring 32 located on the lower side of the mounting plate 2 is set on the left end of the second rod 43, and the mounting ring 32 is rotatably connected to the annular end of the straight cylinder 3. The mounting ring 32 is used to rotatably connect the second rod 43 and the straight cylinder 3.

[0055] In use, first use bolts to fasten the fixing plate 21 to the predetermined position, then connect the camera 1 and other electronic devices to power them to complete the installation of the camera 1. Start the camera 1, and the light formed by the object in the corresponding local area will pass through the through hole 41, the local area in the ring glass 7 located in the through hole 41, and the lens of the camera 1 in sequence. The camera 1 will collect, analyze and identify the light to complete the image capture of the corresponding local area, thereby completing the video monitoring work and realizing security operations.

[0056] In addition, the first motor 33 is started and the rotating shaft 35 is driven to rotate, which in turn causes the top cover 31 and the fixed base 12 to rotate, thereby causing the camera 1 to rotate. This allows for adjustment of the monitoring area of ​​the camera 1, improving the security range, effectively reducing the probability of blind spots, and effectively ensuring security effectiveness and quality.

[0057] When the captured image is blurry, the second motor 8 is activated and the inner plate 73 is driven to rotate, which in turn causes the annular glass 7 to rotate. This allows the area within the through hole 41 of the annular glass 7 to be replaced, thereby adjusting the area within the through hole 41 of the annular glass 7. This effectively reduces the probability of image defects caused by impurities attached to the annular glass 7, and effectively ensures security performance and quality.

[0058] During the rotation of the annular glass 7, relative motion is formed between the annular glass 7 and the two rubber strips 44. At this time, the two rubber strips 44 will clean the left and right surfaces of the annular glass 7 in a timely manner, effectively reducing the probability of impurities on the annular glass 7 causing multiple interferences to the camera 1, and effectively ensuring the security effect and quality.

[0059] Example 2: Figures 1-8 As shown, an outer ring 72 is installed on the annular end of the annular glass 7, and both rubber strips 44 are located inside the outer ring 72. The outer ring 72 provides a mounting carrier for the protrusions 71. Multiple protrusions 71 are equidistantly arranged on the outer end of the outer ring 72, and the protrusions 71 are attached to the annular inner wall of the circular shell 4. The multiple protrusions 71 work together to compress the airbag 51. An installation box 5 is connected to the lower end of the circular shell 4, and the installation box 5 provides installation space for components such as the airbag 51.

[0060] An airbag 51 extending into the circular shell 4 is installed inside the mounting box 5, and the airbag 51 is located on the lower side of the outer ring 72. Gas is delivered outward through the airbag 51. Two partitions 53 are symmetrically installed inside the mounting box 5, and the two partitions 53 are located on the front and rear sides of the connection between the mounting box 5 and the circular box. The two partitions 53 work together to divide the internal space of the mounting box 5 into three cavities.

[0061] Two second tubes 54 are respectively connected to the front and rear ends of the airbag 51, and the two second tubes 54 pass through the two partitions 53 respectively. The airbag 51 is replenished through the second tubes 54. The front and rear end faces of the mounting box 5 are recessed inward to form openings, and the openings extend to the inner wall of the mounting box 5. Through the openings, the outside air can enter the second tubes 54. Two second dustproof nets are respectively installed in the two openings. The second dustproof nets are used to prevent dust from entering the second tubes 54.

[0062] An installation cover 61 is installed at the lower middle part of the installation box 5. The installation cover 61 provides an installation carrier for the oil tank 6. The first pipe 52 is connected to the lower end of the air bag 51, and the lower end of the first pipe 52 passes through the installation box 5 and is connected to the installation cover 61. The first pipe 52 and the two second pipes 54 are equipped with first one-way valves. The first pipe 52 is used to inflate the installation cover 61.

[0063] An annular limiting plate 62 is installed inside the mounting cover 61. The annular limiting plate 62 provides a mounting carrier for the annular rubber pad 63 and restricts the installation position of the oil tank 6. The annular rubber pad 63 is set on the lower end of the annular limiting plate 62. The annular rubber pad 63 is used to seal the connection between the oil tank 6 and the annular limiting plate 62. The oil tank 6 is threaded to the lower end of the mounting cover 61, and the upper end of the oil tank 6 extends into the mounting cover 61 and is squeezed and fitted to the lower end of the annular rubber pad 63. The oil tank 6 is used to store lubricating oil.

[0064] The connecting pipe 91 is installed inside the hollow rod 9. A second one-way valve is installed on the connecting pipe 91. The auxiliary pipe 911, which is arranged in an L-shape, is installed on the lower end of the hollow rod 9. The upper end of the auxiliary pipe 911 passes through the hollow rod 9 and is connected to the connecting pipe 91. The right end of the auxiliary pipe 911 is connected to the left end of the mounting cover 61. The connecting pipe 91 and the auxiliary pipe 911 are used together to make the annular pipe 93 and the suction pipe 912 connected.

[0065] A suction tube 912 arranged in an inverted L-shape is installed inside the oil tank 6. The upper end of the suction tube 912 extends out of the upper side of the oil tank 6 and passes through the annular limiting plate 62. The lateral part of the suction tube 912 is located on the upper side of the annular limiting plate 62. The right end of the auxiliary tube 911 passes through the mounting cover 61 and is connected to the suction tube 912. The suction tube 912 is used to extract the lubricating oil stored in the oil tank 6.

[0066] The annular tube 93 located on the upper side of the straight cylinder 3 is installed on the annular inner wall of the top cover 31, and the left end of the connecting tube 91 passes through the top cover 31 and is connected to the annular tube 93. The annular tube 93 provides a mounting carrier for the nozzle 92. Multiple nozzles 92 located outside the rotating shaft 35 are equidistantly connected on the inner wall of the annular tube 93. The multiple nozzles 92 work together to spray lubricating oil outward. A groove is formed by the downward indentation of the upper end of the cylinder 34, and the cross-section of the groove is a trapezoid with a wider top and a narrower bottom. The groove is used to collect the lubricating oil at the rotating connection between the rotating shaft 35 and the cylinder 34.

[0067] During the rotation of the annular glass 7, the outer ring 72 will rotate, which in turn will cause multiple protrusions 71 to rotate. When a protrusion 71 comes into contact with the airbag 51, the protrusion 71 will squeeze the airbag 51, which will cause the gas in the airbag 51 to be transported into the mounting cover 61 through the first pipe 52. At this time, the air pressure in the sealed space formed by the mounting cover 61 and the oil tank 6 will increase. Under the action of air pressure, the lubricating oil stored in the oil tank 6 will enter the annular pipe 93 along the suction pipe 912, the auxiliary pipe 911 and the connecting pipe 91.

[0068] The lubricating oil inside the annular tube 93 is evenly sprayed into the groove through multiple nozzles 92, and then guided evenly into the rotating connection between the rotating shaft 35 and the cylinder 34 at the bottom of the groove. This achieves comprehensive lubrication of the rotation between the rotating shaft 35 and the cylinder 34, effectively reducing the probability of jamming during adjustment, ensuring safety and quality, and reducing the probability of excessive wear between the rotating shaft 35 and the cylinder 34, thus extending service life. It also achieves linkage between the adjustment movement and the lubrication movement of the annular glass 7, reducing costs.
