Description

Technical Field

[0001] The invention relates to the technical field of cameras, in particular to a heavy-duty pan / tilt camera with high image quality stability. Background Art

[0002] With the rapid development of modern video surveillance technology, heavy-duty PTZ cameras play a vital role in many surveillance fields due to their strong environmental adaptability and flexible shooting capabilities. However, traditional heavy-duty PTZ cameras still have many shortcomings in terms of image quality stability, shooting flexibility, and equipment maintenance, and cannot meet the growing surveillance needs.

[0003] In terms of image quality stability, traditional heavy-duty PTZ cameras face particularly severe challenges. Due to the fixed installation method of the lens and the optical glass, it is difficult for the camera to ensure that the lens is always accurately facing the optical glass, which directly leads to fluctuations in image quality. This fluctuation will not only reduce the clarity of the monitoring screen, making the picture blurry or distorted, but may also cause serious interference to subsequent image analysis and recognition work. Especially in complex scenes, such as large changes in light, long shooting distances, complex and changeable environments, the problem of image quality stability is more prominent, seriously affecting the efficiency and reliability of the monitoring system. In terms of shooting flexibility, although traditional heavy-duty PTZ cameras can achieve horizontal and vertical rotation through the PTZ, the movement range of the lens itself is still limited, and during long-term movement, the lens may shift. , so that it is no longer at the same level as the optical glass, which limits the camera's ability to capture wider scenes or specific details, making it possible for the monitoring screen to not fully cover or clearly present the target area. In addition, if the lens lacks a precise control system during movement, it is prone to jitter or offset, which further reduces the shooting effect and makes the monitoring screen unstable or difficult to observe. The structure of traditional heavy-duty PTZ cameras is often complex, which makes maintenance difficult. Once the camera fails or needs cleaning and maintenance, maintenance personnel often need to disassemble a large number of parts to access the internal components, which not only increases maintenance costs and time costs, but may also damage the equipment itself or shorten its service life. In addition, the complex structure may also increase the failure rate and maintenance difficulty of the equipment, threatening the reliability and stability of the monitoring system.

[0004] Therefore, based on the above search and in combination with the prior art, a heavy-duty pan-tilt camera with high image quality stability is proposed to solve the above problems. Summary of the invention

[0035] Through the above-mentioned features, the camera assembly 7 and the zoom laser lens 8 can be moved forward and backward and left and right. Specifically, when the camera assembly 7 and the zoom laser lens 8 need to move left and right, the driving motor 2 19 is turned on to rotate the threaded rod 2 17 connected to the output shaft of the driving motor 2 19, so that the two sliding blocks 18 threadedly connected to the threaded rod 2 17 are moved, so as to realize the left and right movement of the camera assembly 7 and the zoom laser lens 8.

The adjusted camera assembly 7 and the zoom laser lens 8 will be on the same horizontal line with the optical glass 5 and the laser receiver 30 to avoid changes in the stability of their image quality.

[0040] As a preferred implementation in this embodiment, please refer to Figure 3 to Figure 5 As shown, the ventilation assembly includes: two connecting plates 31, the two connecting plates 31 are respectively fixedly mounted on the inner wall of the protective cover 4, one side of one of the connecting plates 31 is fixedly mounted with an electric push rod 2 32, the output shaft of the electric push rod 2 32 is connected with a sealing plate 33, the sealing plate 33 is slidably connected to the inside of the connecting plate 31, the right side wall of the protective cover 4 is provided with a vent hole 1 34, the left side wall of the protective cover 4 is provided with a vent hole 2 35, a plurality of flow tubes 36 are arranged between the two connecting plates 31, and a temperature sensor 37 is fixedly mounted on the inner wall of the protective cover 4.

[0041] Through the above-mentioned features, when the temperature inside the protective cover 4 is too high, the interior can be cooled. Specifically, when the temperature sensor 37 detects that the temperature inside the protective cover 4 is too high, it will transmit data to the processor 9. The processor 9 will open the electric push rod 2 32, so that the sealing plate 33 connected to the output shaft of the electric push rod 2 32 slides out from the inside of the electric push rod 2 32. At this time, the fan inside the connecting plate 31 starts to work, and the external wind is sucked in through the air vent 2 35 through the flow tube 36, and finally discharged from the air vent 2 35. The flow tube 36 is made of a material with good heat conduction effect.

[0042] As a preferred implementation in this embodiment, please refer to Figure 8 and Fig. 9 As shown, a plurality of iron blocks 38 are fixedly mounted on the rear side wall of the cover plate 6, and a slot 39 is provided on the side walls of the plurality of iron blocks 38. A bar magnet 40 is fixedly mounted on the rear side wall of the protective cover 4. The iron blocks 38 and the bar magnet 40 are attracted to each other. When the cover plate 6 needs to be closed, it is only necessary to engage the slot 39 with the bar magnet 40, which is convenient and quick.

[0043] Working principle:

[0044] During use, when the camera body 3 needs to be rotated horizontally, the pan-tilt body 2 rotates on the top surface of the mounting base 1 to ensure that the camera body 3 can capture a wider scene. At the same time, the camera body 3 rotates up and down above the pan-tilt body 2 through its internal transmission mechanism, further widening the shooting range of the camera. During use, if the camera assembly 7 and the zoom laser lens 8 need to move left and right to adjust the shooting angle, the drive motor 19 is started, and the output shaft of the drive motor 19 drives the threaded rod 17 to rotate, thereby causing the two sliding blocks 18 threadedly connected to the threaded rod 17 to move left and right inside the sliding groove 16. A rotating disk 20 is fixed to the top surface of the sliding block 18, so the camera assembly 7 and the zoom laser lens 8 also move left and right accordingly. Similarly, if the camera assembly 7 and the zoom laser lens 8 need to move forward and backward, the driving motor 14 is started, and the output shaft of the driving motor 14 drives the threaded rod 13 to rotate, so that the moving block 12 threadedly connected to the threaded rod 13 slides forward and backward inside the moving groove 11. The movement of the moving block 12 drives the connecting block 15 and the sliding block 18 above it to move synchronously, thereby realizing the forward and backward movement of the camera assembly 7 and the zoom laser lens 8. In order to ensure that the camera assembly 7 and the zoom laser lens 8 can face the optical glass 5, the present invention is provided with an adjustment component. When the laser emitted by the laser transmitter 29 does not accurately shoot at the center of the laser receiver 30, the laser receiver 30 transmits a signal to the processor 9, and the processor 9 controls the electric push rod 26 or the electromagnet 23 to work according to the offset. The extension and retraction of the electric push rod 26 drives the connecting plate 25 and the camera assembly 7 or the zoom laser lens 8 above to make fine adjustments; and the opening of the electromagnet 23 attracts the iron ball 24 and the connecting plate 25 through magnetic force to adjust the angle until the camera assembly 7 and the zoom laser lens 8 are respectively facing the two optical glasses 5. During use, if the temperature inside the protective cover 4 is too high, the temperature sensor 37 will detect this change and transmit a signal to the processor 9, and the processor 9 will The processor 9 then controls the electric push rod 2 32 to work, so that the sealing plate 33 slides out from the inside of the connecting plate 31 and opens the ventilation channel. At this time, the external wind is sucked into the protective cover 4 through the vent hole 2 35, and after heat exchange through the flow tube 36 made of a material with good heat conduction effect, it is discharged from the vent hole 1 34, thereby achieving cooling inside the protective cover 4. In order to maintain the airtightness of the protective cover 4, a plurality of iron blocks 38 are provided on the rear side wall of the cover 6. These iron blocks 38 and the bar magnets 40 on the rear side wall of the protective cover 4 are mutually attracted. At the same time, the side wall of the iron block 38 is provided with a slot 39. When the cover 6 is closed, the slot 39 engages with the bar magnet 40, thereby enhancing the stability of the cover 6.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
