Abstract
Description
Technical Field
[0001] The utility model relates to the field of underwater video recording, in particular to an underwater image video recording device with lighting and anti-interference function. Background Art
[0002] At present, underwater video recording devices can be roughly divided into two categories. The first category is that the lighting equipment and the video equipment are divided into two independent devices. When working, both devices need to be turned on at the same time, which can basically meet the use requirements. This design has the following three shortcomings: First, the separate design of the lighting equipment and the video equipment greatly increases the number of parts, which not only indirectly increases the material cost of the equipment, but also increases the design workload; second, in many actual underwater environments, there is often not much installation space for such equipment, and miniaturization and integrated design become the priority factors. Separating into two devices will not meet the installation environment with limited space; third, the equipment used in the underwater environment has extremely strict sealing requirements. If a separate design is adopted, the sealing of both devices must be done at the same time. If one of the devices fails due to water ingress or other factors, both devices will be unusable, and the reliability of the equipment will be reduced. The second category is that the lighting and video equipment are made into an integrated device, but the LED light and the camera share a channel, and a protective glass is used to allow light to be emitted and images to be transmitted back at the same time. This design also has three defects. First, the light from the LED lamp will first hit the glass. At this time, most of the light is refracted into the water, and a small amount of light is reflected into the camera objective, causing the image observed by the camera to be interfered by the reflected light; second, when this design is adopted, the glass area will inevitably increase a lot, and the water pressure will also increase, greatly increasing the risk of glass breakage; third, microorganisms often attach when underwater lighting is used. If it is the same glass window, it will directly cause the camera objective to be blocked, making it impossible to carry out recording. Utility Model Content

Detailed implementation mode
[0021] As Figures 1 to 3 shown, an underwater image recording device with lighting anti-interference includes a multi-window housing 1. A cover plate 2 is fixedly installed at the bottom of the multi-window housing 1. A camera channel 101 is provided in the middle of the top of the multi-window housing 1, and lighting channels 102 are provided on both sides of the camera channel 101. Protection glasses are fixedly installed on the camera channel 101 and the lighting channels 102. A glass pressure plate 3 is provided on the protection glasses, and the glass pressure plate 3 is fixedly connected to the multi-window housing 1 by bolts;
[0022] Multiple layers of circuit boards 8 and a camera 7 are fixedly installed on the cover plate 2. The camera 7 is arranged on the top of the multiple layers of circuit boards 8. The camera 7 and the circuit board 8 are connected by an adapter stud 9. The end of the camera 7 is located in the camera channel 101, and a lamp board 14 and lamp beads 15 are fixedly installed in the lighting channels 102.
[0023] The independent camera channel 101 and lighting channels 102 do not interfere with each other, avoiding the interference of lighting on the image observed by the camera 7. The glass pressure plate 3 seals and fixes the protection glasses on the corresponding camera channel 101 and lighting channels 102, ensuring its sealing performance without affecting lighting and imaging. The lens of the camera 7 is located at the center of the camera window protection glass 5 in the camera channel 101, ensuring a wide viewing field.
[0024] The multi-window housing serves as the basic framework of the entire device, providing a strong protective environment to prevent damage to internal components caused by underwater pressure and external impacts. The cover plate is installed at the bottom of the housing to close the housing and ensure its waterproof performance. The camera channel and lighting channels are respectively arranged in the middle and on both sides of the top of the housing. In this way, the interference of the lighting system on the camera system can be effectively avoided, ensuring the clarity of the captured image.
[0025] The protection glasses are installed on the camera channel and lighting channels, which can not only prevent water from entering but also maintain the light transmittance, ensuring that the shooting effect is not affected. The glass pressure plate is fixed on the housing by bolts, firmly pressing the protection glasses, enhancing the sealing performance and durability of the device.
[0026] The multi-layer circuit board is mounted on the cover plate and is responsible for processing data from the camera and other sensors. The camera is located above the circuit board and is connected to the circuit board through an adapter stud. Its lens is facing the protective glass in the camera channel and can capture a wide viewing angle. The light board and light beads are installed in the lighting channel to provide the necessary light source for underwater shooting. At the same time, since it is separated from the camera channel, it reduces the impact of phenomena such as light reflection on the imaging quality.
[0027] By isolating the lighting system from the imaging system, problems such as overexposure or reflection are effectively avoided, making the underwater images clearer and more real. Whether in shallow water areas or deep sea areas, this device can work stably and is suitable for detection and recording tasks in a variety of underwater environments.
[0028] Preferably, a watertight socket 4 is fixedly provided on one side of the multi-window housing 1, and a first sealing ring 10 is provided between the cover plate 2 and the multi-window housing 1.
[0029] The watertight socket 4 is installed on one side of the multi-window housing and is mainly used to connect external power supplies, data transmission cables or other accessories. The design of the watertight socket ensures that even in an underwater environment, safe power supply and data exchange can be carried out without causing short circuits or damage due to water intrusion. This design is particularly important for long-term or long-distance underwater operations, enabling remote control of the device and real-time data transmission, improving the application flexibility and operation convenience of the device.
[0030] The first sealing ring 10 is provided between the cover plate and the multi-window housing to enhance the sealing performance of the two. The sealing ring is usually made of corrosion-resistant and aging-resistant materials such as silicone rubber or ethylene propylene diene monomer rubber, and can maintain good sealing effects under harsh conditions such as high pressure and low temperature. The presence of the first sealing ring not only helps prevent water from seeping in through the gap between the cover plate and the housing, but also can absorb a certain amount of mechanical vibration, protecting the internal precision components from damage.
[0031] Preferably, one end of the protective glass abuts against the glass pressing plate 3 through a buffer pad 13, and the other end abuts against the inside of the camera channel 101 and the lighting channel 102 through a sealing pad 12.
[0032] The buffer pad 13 is installed at one end of the protective glass, between the glass and the glass pressing plate. The buffer pad is usually made of soft and elastic materials such as silica gel or foam rubber. Its main functions are: absorbing external impact forces to protect the protective glass from damage; increasing the sealing between the glass and the glass pressing plate to prevent moisture penetration; ensuring uniform distribution of the pressure of the glass pressing plate on the protective glass and avoiding glass breakage caused by excessive local pressure.
[0033] The gasket 12 is installed at the other end of the protective glass, between the glass and the inner walls of the camera channel 101 and the lighting channel 102. The gasket is also made of corrosion-resistant and aging-resistant materials, such as silicone rubber or EPDM. Its main functions are: to ensure the sealing between the protective glass and the inner wall of the channel, prevent moisture from entering the interior, and protect electronic components such as cameras and lamp boards. To help fix the position of the protective glass, keep it stable in the channel, and prevent it from shifting due to changes in water pressure. In addition to waterproofing, it can also prevent dust and other impurities from entering the channel and keep the optical surface clean.
[0034] The double protection of the buffer pad and the gasket ensures the sealing of the entire device, and can effectively prevent moisture penetration even in deep water environments. Through the protection of the buffer pad and the gasket, the protective glass is not easily affected by external impacts and abrasions, and maintains its optical performance. These design details improve the overall durability and reliability of the device, extend the service life of the equipment, and reduce the maintenance cost.
[0035] Preferably, a groove is provided on the side of the glass pressing plate 3 opposite to the multi-window housing 1.
[0036] A second sealing ring 11 is provided on the outside of the protective glass, and the second sealing ring 11 abuts against the grooves on the glass pressing plate 3 and the multi-window housing 1.
[0037] The groove is used to accommodate the second sealing ring 11 to ensure that the sealing ring can be correctly positioned during installation without shifting or deforming. The double protection of the first sealing ring 10 and the second sealing ring 11 ensures the sealing of the entire device, and can effectively prevent moisture penetration even in deep water environments. By setting sealing rings at multiple contact points, all possible water inlet paths are ensured to be blocked.
[0038] Preferably, one side of the protective glass located on the lighting channel 102 is a matte surface, and the other side is a smooth surface. The matte surface faces outward and the smooth surface faces inward. The matte surface of the lighting window protective glass 6 can scatter light, make the light more evenly distributed, reduce glare and hot spots, and improve the uniformity and softness of the lighting effect. The matte surface can reduce the reflection of external light, avoid strong light reflecting onto the camera lens and affecting the shooting effect. The matte surface is not easily attached with scale and stains, which is convenient for cleaning and maintenance.
[0039] The smooth surface can minimize the loss of light, ensure that more light can pass through the protective glass and reach the underwater environment. Protect the lamp board and lamp beads: The smooth surface can reduce the scattering of internal light, ensure that the light emitted by the lamp board and lamp beads can be efficiently transmitted, and improve the lighting efficiency.
[0040] Preferably, the protective glass located on the lighting channel 102 is fully transparent glass. The fully transparent glass of the camera window protective glass 5 ensures the maximum brightness of the lighting light, improving the visibility of the underwater environment. It reduces refraction and reflection, ensuring uniform distribution of light and avoiding problems of local overbrightness or overdarkness.
[0041] The high light transmittance and reduced refraction and reflection improve the clarity of lighting, ensuring high-quality underwater images. It maintains spectral characteristics, ensuring high color restoration of underwater images and truly reflecting the colors of the underwater environment.
[0042] The corrosion resistance and compressive resistance of the fully transparent glass ensure the long-term stable use of the device in the underwater environment. The surface of the fully transparent glass is easy to clean, reducing the workload of maintenance.
[0043] The above embodiments are only the preferred technical solutions of the present utility model and should not be regarded as limitations on the present utility model. The protection scope of the present utility model shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present utility model.
