Description

Technical Field

[0001] This invention relates to the field of underwater imaging and monitoring technology, and in particular to a high-definition underwater camera. Background Technology

[0002] High-definition underwater cameras are widely used in marine scientific research, underwater engineering, aquaculture, and security monitoring due to their high-definition image quality. However, current technology faces several challenges: First, high-definition cameras generate a large amount of heat during operation, and traditional air-cooling methods are ineffective in the underwater environment. If the heat cannot be dissipated in time, it will lead to increased image noise and decreased frame rate, seriously affecting equipment performance and lifespan. Second, existing underwater cameras have limitations in installation adaptability, making it difficult to quickly and stably install them on underwater bodies of different sizes. The wiring design also lacks optimization, making cables susceptible to damage due to bending. Therefore, there is an urgent need to develop a high-definition underwater camera technology solution that can efficiently dissipate heat, provide stable protection, and is easy to install and maintain. Utility Model Content

[0003] To solve the above problems, this utility model provides a high-definition underwater camera, the specific solution of which is as follows:

[0004] A high-definition underwater camera includes a protective cover and a camera module. The protective cover further includes a cover body and a base, and the protective cover has a cable outlet hole. The cover body and the base are connected by a snap-fit ​​mechanism. The camera module includes a circuit board and a camera assembly, which are linearly connected. The camera assembly is mechanically fixed to the circuit board by screws. The protective cover, through the combination of the cover body and the base, forms a first cavity and a second cavity. The first cavity is configured to accommodate the camera module, and its shape is adapted to the outer contour of the camera module. The camera module is mechanically fixed in the first cavity, and the second cavity surrounds the outer periphery of the first cavity.

[0005] Furthermore, the camera assembly includes a camera and a base. The camera has an external thread structure, and the base has a corresponding internal thread hole. By screwing the external thread of the camera into the internal thread hole of the base, the camera is securely fixed to the base by rotating the thread.

[0006] Furthermore, the base incorporates an infrared cut-off filter switcher that works in conjunction with the circuit board to control the automatic switching between day and night modes.

[0007] Furthermore, the first cavity in the cover has two symmetrically positioned extensions, one of which has a hollowed-out section at the same level as the wire outlet for leading wires outward; the other extension has a groove below it.

[0008] Furthermore, the protective cover base is provided with two injection holes and two limiting buckles; the injection holes are located above the outer extension; the limiting buckles are symmetrically fixed to the side wall of the base.

[0009] Furthermore, the underwater camera can inject resin into the injection hole to isolate the camera module from water.

[0010] Furthermore, the limiting buckle is provided with a binding hole for binding wire and a protrusion for buckle design. Its lower part forms a guide slope with an angle α with the horizontal plane, so that the limiting buckle can be tightly attached and fixed to the surface of the circular object. Stable installation is achieved by the radial clamping force generated by the wedge fit.

[0011] Furthermore, the included angle α ranges from 15° to 45°.

[0012] Furthermore, the cover is provided with a circular through hole adapted to the outer contour of the camera, and one or more water inlets; the inner diameter of the circular through hole matches the maximum outer diameter of the camera; the water inlets are hollowed out and penetrate the wall of the cover.

[0013] The beneficial effects of this utility model are as follows:

[0014] The cover and base are connected by a snap-fit ​​mechanism, which facilitates installation and disassembly while ensuring the sealing and stability of the connection.

[0015] Resin is injected through the injection hole to isolate the camera module from water, effectively preventing moisture from entering the camera module, protecting electronic components from water damage, and extending the service life of the equipment.

[0016] The limit buckle is equipped with a binding hole and a protrusion for the buckle design. The lower part of the protrusion forms a guide slope, which allows the limit buckle to be tightly attached and fixed to the surface of a circular object. Stable installation is achieved through the radial clamping force generated by the wedge fit. This design adapts to the needs of different installation environments and improves the versatility of the equipment.

[0017] The housing has a circular through-hole that matches the outer contour of the camera, ensuring that the camera can accurately capture underwater images. At the same time, the inner diameter of the circular through-hole matches the maximum outer diameter of the camera, reducing light refraction and scattering and improving image quality.

[0018] Employing a high-definition camera, which generates significant heat during operation, the enclosure features one or more water inlets that penetrate the enclosure wall, allowing external liquid to enter the second chamber. This creates an efficient water-cooling heat dissipation channel, rapidly transferring the heat generated by the camera module to the flowing liquid. This effectively prevents performance degradation issues such as increased image noise and decreased frame rate caused by high temperatures, ensuring that the high-definition camera continuously outputs stable and clear images under long-term, high-load operation, significantly extending the device's lifespan.

[0019] By integrating an infrared cut-off filter switcher into the base and working in conjunction with the circuit board, automatic switching between day and night modes is achieved. During the day, the infrared cut-off filter blocks infrared light, restoring true colors; at night, it automatically switches to a full-spectrum filter, working with an infrared supplemental light to improve imaging in low light conditions, ensuring clear and natural images under various lighting conditions. Employing a low-light infrared method to receive infrared light, it avoids generating visible light that could stimulate the normal growth of aquatic organisms in aquaculture scenarios.

[0030] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the following description is provided with accompanying drawings of the relevant technical solutions in the embodiments of this application or the prior art. It should be understood that the accompanying drawings described below are only for the purpose of clearly illustrating some embodiments of the technical solutions in this application. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.

[0031] like Figures 1 to 7 As shown, this utility model provides a high-definition underwater camera, including a protective cover and a camera module. The protective cover consists of a cover body (1) and a base (2), which are detachably connected by a snap-fit ​​connection structure. A cable outlet hole (3) is provided on the protective cover, which is used to lead out the connection cable of the camera module so as to realize data transmission and power supply connection with external devices.

[0032] The protective cover is formed by combining a cover body (1) and a base (2) to form a first cavity (6) and a second cavity (7). The shape of the first cavity (6) is adapted to the outer contour of the camera module to accommodate the camera module. The camera module is mechanically fixed inside the first cavity (6) to ensure its stability in the underwater environment. The second cavity (7) surrounds the outer periphery of the first cavity and is used to introduce water flow to achieve heat dissipation.

[0033] The camera module includes a circuit board (4) and a camera assembly (5), which are linearly connected. The camera assembly (5) is mechanically fixed to the circuit board by screws. The camera assembly (5) consists of a camera (51) and a base (52). The camera (51) has an external thread structure, and the base has a corresponding internal thread hole. During installation, the external thread of the camera (51) is screwed into the internal thread hole of the base, so that the camera (51) is firmly fixed to the base (52) by rotating the thread. This threaded connection method is not only firmly installed, but also facilitates the disassembly and replacement of components such as lenses, making it convenient for later maintenance and upgrades.

[0034] The base (52) has a built-in infrared cut-off filter switcher. Through the circuit board (4) and the switcher, it can automatically switch between day and night modes, thereby optimizing the imaging effect. When there is sufficient light during the day, the circuit control board will drive the switcher to switch and position the infrared cut-off filter to work, blocking infrared light from entering the sensor. At this time, the CCD (charge-coupled device) or CMOS (complementary metal oxide semiconductor) can restore the true colors and avoid the interference of infrared light on color restoration. When there is insufficient visible light at night or the water is relatively turbid, the infrared cut-off filter will automatically move away and the full-spectrum optical filter will start working. It can sense the infrared light of the infrared lamp and receive infrared light in a low-light infrared mode (in the aquaculture scenario, it will not produce visible light to stimulate the normal growth of underwater organisms). In conjunction with the infrared supplement light, it can achieve low-light black and white imaging, so that the CCD or CMOS can make full use of all the light, thereby greatly improving the night vision performance of the infrared camera and making the whole picture clear and natural. This switching mechanism not only solves the problem of color reproduction due to infrared light interference during the day, but also effectively improves the clarity and naturalness of nighttime imaging, enabling images to maintain high quality under different lighting conditions.

[0035] The housing (1) is provided with a circular through hole (14) that matches the outer contour of the camera (51). The inner diameter of the circular through hole (14) matches the maximum outer diameter of the camera (51), ensuring that the camera (51) can be installed smoothly and work normally, so as to ensure that the camera (51) can be installed stably and collect underwater image information through the through hole. In addition, the housing (1) is also provided with one or more water inlet holes (15). The water inlet holes (15) are hollow and penetrate through the wall of the housing, allowing water to enter the second cavity (7), thereby removing the heat generated by the camera module during operation and improving the heat dissipation efficiency, especially in a water flow environment.

[0036] The first cavity (6) has two symmetrically positioned extensions (8). One extension (8) at the same level as the cable outlet has a cutout for threading the connecting cable of the camera module. The other extension (8) has a groove (9) below it. This groove (9) is mainly used to facilitate the injection of resin into the camera position, so as to achieve full coverage of the camera with resin, thereby enhancing the waterproof performance of the camera.

[0037] The base (2) is provided with two injection holes (10), and the injection holes (10) are located above the extension (8). Resin can be injected into the protective cover through the injection holes (10) to isolate the camera module from water and further ensure the normal operation of the camera module in the underwater environment.

[0038] Two limiting buckles (11) are symmetrically fixed to the side wall of the base (2). The limiting buckles (11) are provided with binding holes (12) for binding wires, which facilitates the arrangement and fixation of the connecting wires of the camera (51). At the same time, the limiting buckles (11) are also provided with protrusions (13) for buckle design. The lower part of the protrusion has a guide slope. The angle α between the guide slope and the horizontal plane is in the range of 15° to 45°, so that the limiting buckles (11) can be tightly attached to the surface of the circular object. The radial clamping force generated by the wedge fit realizes the stable installation of the underwater camera. This design is not only suitable for circular supports, but can also be adapted to other shapes of mounting surfaces, providing a variety of fixing solutions and enhancing the applicability and versatility of the equipment.

[0039] During installation, the camera assembly (5) is first fixed to the circuit board with screws to form a camera module. Then, the camera module is placed into the first cavity (6) of the protective cover and fixed mechanically. Next, the cover (1) and the base (2) of the protective cover are connected together by snap-fit. Resin is injected into the protective cover through the injection hole (10) on the base (2), and the resin fills the area around the camera module to isolate the camera module from water. Finally, the installed underwater camera is fixed in the required position by the limiting buckle (11) on the base (2). The radial clamping force generated by the guide slope and wedge of the limiting buckle (11) ensures stable installation of the camera.

[0040] In actual operation, the camera collects underwater image information and transmits the collected image signals to external devices through a connecting cable to achieve underwater high-definition video recording. At the same time, water flows into the second cavity (7) through the inlet (15) and flows around the first cavity (6), quickly transferring the heat generated by the camera module to the water. This effectively avoids performance degradation problems such as increased image noise and decreased frame rate caused by high temperature, ensuring that the high-definition camera can continuously output stable and clear images under long-term, high-load operation, and significantly extending the service life of the equipment.

[0041] Specific implementation methods have been provided above, but this utility model is not limited to the described implementation methods. The basic idea of ​​this utility model lies in the above basic scheme. For those skilled in the art, designing various modified models, formulas, and parameters based on the teachings of this utility model does not require creative effort. Changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model still fall within the protection scope of this utility model.
