Description

Technical Field

[0001] This utility model relates to the field of underwater equipment technology, specifically to an underwater visible light fixing device. Background Technology

[0002] With the booming development of the marine tourism industry, underwater activities such as diving are becoming increasingly popular. However, the complex underwater environment and the susceptibility of signal propagation to interference pose significant challenges to underwater positioning and safety. Among existing underwater positioning technologies, ultrasonic positioning systems have several problems. For example, they are easily affected by environmental factors such as temperature and water flow. Various natural and man-made noise sources in the underwater environment, such as sounds from marine life, currents, and crowds, can mask ultrasonic signals, reducing the signal-to-noise ratio and making it difficult for the receiver to accurately detect and identify the signal, increasing the probability of positioning errors. Furthermore, to ensure positioning accuracy, ultrasonic positioning requires high-precision equipment, including complex and expensive transducers. These transducers not only increase system costs but also require continuous calibration and adjustment due to the variable underwater environment, further increasing maintenance costs.

[0003] Against this backdrop, visible light positioning technology has gradually gained attention. It utilizes visible light for location determination, using common visible light sources such as lighting fixtures as signal transmitters, providing both illumination and positioning capabilities. Short-wavelength blue light (wavelengths between 400nm and 460nm) is particularly suitable for underwater positioning because water absorbs it less and it propagates well underwater. However, existing underwater visible light devices have some shortcomings in installation and fixation. For example, some devices suffer from poor stability, making it difficult to maintain a fixed position in complex underwater environments; others have poor sealing performance, easily leading to water ingress damage to internal electronic components, affecting the normal operation and lifespan of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an underwater visible light fixing device. This invention can improve stability and reliability in underwater environments, and also has the advantage of good sealing, which can ensure the normal operation of internal components.

[0005] The technical solution of this utility model is as follows: an underwater visible light fixing device, including a chassis, a connecting rod fixedly disposed in the middle of the chassis, and a base fixedly disposed at the upper end of the connecting rod; a visible light positioning lamp is detachably connected to the base; the visible light positioning lamp includes a lamp holder threadedly connected to the base, and multiple inclined upward support rods are distributed in a ring at the upper end of the lamp holder; a ring light source is connected between the upper ends of the support rods.

[0006] The aforementioned underwater visible light fixing device has a circular base with multiple fixing holes arranged in a ring on the base.

[0007] The aforementioned underwater visible light fixing device has a connecting rod made of steel bars, and the surface of the connecting rod is coated with zinc-based anti-corrosion paint.

[0008] The aforementioned underwater visible light fixing device has a connecting cavity inside the base, which is threadedly connected to the lamp holder.

[0009] The aforementioned underwater visible light fixing device has an internal mounting cavity in the lamp holder; the lower end of the lamp holder is provided with a cover plate for sealing the mounting cavity.

[0010] The aforementioned underwater visible light fixing device has an annular groove on the cover plate, a first sealing ring inside the annular groove, and a first embedding groove on the first sealing ring; a second sealing ring is provided on the side wall of the lamp holder, and a first protrusion is provided on the second sealing ring embedded in the first embedding groove.

[0011] The aforementioned underwater visible light fixing device has a mounting groove at the end of the side wall of the lamp holder, and a first snap-fit ​​on the side wall of the mounting groove; the second sealing ring is L-shaped, and a first locking block that mates with the first snap-fit ​​is provided on the vertical surface of the second sealing ring, and a pressing part is provided on the horizontal surface of the second sealing ring; the end of the inner wall of the mounting groove is engaged between the vertical surface of the second sealing ring and the pressing part.

[0012] The aforementioned underwater visible light fixing device also has a buckle groove extending from the lower side of the mounting groove, and a second latch on the groove wall; the cover plate is provided with a second buckle block that cooperates with the second latch.

[0013] The aforementioned underwater visible light fixing device has a compression protrusion in the middle of the bottom of the cover plate.

[0014] The aforementioned underwater visible light fixing device also includes a truncated pyramid located in the middle of the annular light source at the upper end of the lamp holder, and a photosensitive camera is mounted on the upper end of the truncated pyramid.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The circular base of this invention increases the contact area with the mounting surface, resulting in a more even distribution of the device's center of gravity underwater and effectively reducing the risk of swaying. Multiple annularly distributed fixing holes accommodate various sizes of fixing bolts, allowing for flexible selection of installation positions and methods. Stable installation is achieved regardless of whether the underwater structure is flat or curved. In areas with rapid currents, these fixing holes firmly secure the device, resisting the impact of the water flow and ensuring normal operation. The steel-reinforced connecting rod of this invention possesses high strength and rigidity, capable of withstanding the device's own weight underwater as well as external forces such as water flow and pressure, preventing deformation or damage due to stress. Its zinc-based anti-corrosion paint forms a dense protective film, isolating the steel reinforcement from water and oxygen corrosion, preventing rust and strength reduction, extending the device's underwater service life, and ensuring long-term stable operation. Furthermore, the visible light positioning light's lamp holder and base are connected by threads, making operation simple and convenient. When the device malfunctions or requires component upgrades, maintenance personnel can easily unscrew the lamp holders by hand or with a simple wrench without the need for complex tools. This allows them to inspect, repair, or replace internal components such as the ring light source and photosensitive camera, saving maintenance time and costs and improving equipment efficiency.

[0017] 2. The first and second sealing rings of this utility model form a double sealing structure. The first sealing ring is installed in the annular groove of the cover plate, initially preventing water intrusion. The first protrusion on the second sealing ring is embedded in the first groove of the first sealing ring, filling any gaps and enhancing the sealing effect. This effectively prevents water from penetrating into the mounting cavity of the lamp holder, protecting the internal electronic components. Simultaneously, the second sealing ring is L-shaped, with its first locking block on its vertical surface aligning with the first locking slot of the mounting groove on the side wall of the lamp holder. The end of the inner groove wall of the mounting groove is engaged between the vertical surface of the second sealing ring and the pressing part. This structure ensures the second sealing ring is securely installed, preventing displacement or detachment under underwater pressure and water flow impact, maintaining good sealing performance. Furthermore, the retaining groove on the lower side of the mounting groove cooperates with the second retaining block on the cover plate, further reinforcing the connection between the cover plate and the lamp holder, reducing gaps, and improving overall sealing. Furthermore, the extrusion protrusion in the middle of the bottom of the cover plate applies a certain pressure to the cover plate after installation. On the one hand, it makes the cover plate more stable and reduces the shaking of the base. On the other hand, the applied pressure can make the first sealing ring and the second sealing ring fit more tightly and enhance the sealing effect. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0026] Example: An underwater visible light fixing device, such as Figure 1 As shown, it includes a chassis 1, a connecting rod 2 fixedly mounted in the middle of the chassis 1, and a base 3 fixedly mounted at the upper end of the connecting rod 2; a visible light positioning lamp 4 is detachably connected to the base 3; as shown... Figure 2 As shown, the base 3 has a connecting cavity 12 inside; as Figure 3 As shown, the visible light positioning lamp 4 includes a lamp holder 5, and a connecting cavity 12 is threadedly connected to the lamp holder 5. This detachable threaded connection facilitates the installation and removal of the visible light positioning lamp 4, and makes it convenient for maintenance and replacement. Figure 4As shown, the lamp holder 5 has an internal mounting cavity 7; the mounting cavity 7 is used to install various electronic components, batteries, and circuits; the lower end of the lamp holder 5 is provided with a cover plate 13 for sealing the mounting cavity 7 to prevent water from entering the mounting cavity 7 and damaging the internal components. Multiple upwardly inclined support rods 6 are distributed in a ring at the upper end of the lamp holder 5; a ring-shaped light source 8 is connected between the upper ends of the support rods 6. The ring-shaped light source 8 is powered by a battery inside the mounting cavity 7 to provide visible light illumination, illuminating the underwater environment and compensating for insufficient underwater light. The base 1 is circular, and multiple fixing holes 11 are distributed in a ring on the base 1. The design of the base 1 facilitates fixing the device to the required underwater position using bolts or other connecting parts, and the circular base 1 helps to distribute the weight of the device, improving the stability of the fixation. The connecting rod 2 is made of steel reinforcement, and the surface of the connecting rod 2 is coated with zinc-based anti-corrosion paint. The steel reinforcement ensures the strength of the connecting rod 2, enabling it to withstand the weight of the device underwater and external forces such as water flow. Zinc-based anti-corrosion paint effectively prevents the connecting rod 2 from rusting and corroding in the underwater environment, extending the device's service life. The upper end of the lamp holder 5 is also equipped with a truncated pyramid 9 located in the center of the annular light source 8. A photosensitive camera 10 is mounted on the upper end of the pyramid 9. The photosensitive camera 10 can be used to receive customer attendance information and transmit it to the backend.

[0027] Preferably, such as Figure 5As shown, the cover plate 13 is provided with an annular groove 14, and a first sealing ring 15 is provided in the annular groove 14. The first sealing ring 15 has a first embedding groove 16. A second sealing ring 17 is provided on the side wall of the lamp holder 5. The second sealing ring 17 has a first protrusion 18 embedded in the first embedding groove 16. An installation groove 19 is provided at the end of the side wall of the lamp holder 5. A first snap-fit ​​20 is provided on the side wall of the installation groove 19. The second sealing ring 17 is L-shaped. A first snap-fit ​​block 21 that cooperates with the first snap-fit ​​20 is provided on the vertical surface of the second sealing ring 17. A pressing part 22 is provided on the horizontal surface of the second sealing ring 17. The end of the inner wall of the installation groove 19 is snapped between the vertical surface of the second sealing ring 17 and the pressing part 22. A buckle groove 23 extends from the lower side of the installation groove 19. A second snap-fit ​​24 is provided on the wall of the buckle groove 23. A second snap-fit ​​block 25 that cooperates with the second snap-fit ​​24 is provided on the cover plate 13. A compression protrusion 26 is provided in the middle of the bottom of the cover plate 13. In this embodiment, the first sealing ring 15 and the second sealing ring 17 form a double sealing structure. The first sealing ring 15 is installed in the annular groove 14 of the cover plate 13 to initially block moisture intrusion. The first protrusion 18 on the second sealing ring 17 is embedded in the first groove 16 of the first sealing ring 15 to fill any gaps, enhance the sealing effect, and effectively prevent moisture from penetrating into the mounting cavity 7 of the lamp holder 5, protecting the internal electronic components. The second sealing ring 17 is L-shaped, and the first locking block 21 on its vertical surface is precisely matched with the first locking slot 20 of the mounting groove 19 on the side wall of the lamp holder 5. The end of the inner groove wall of the mounting groove 19 is engaged between the vertical surface of the second sealing ring 17 and the compression part 22. This structure ensures that the second sealing ring 17 is installed firmly, preventing displacement or detachment under underwater pressure and water flow impact, and maintaining good sealing performance. The latching groove 23 on the lower side of the mounting groove 19 cooperates with the second latching block 25 on the cover plate 13 to further strengthen the connection between the cover plate 13 and the lamp holder 5, reduce gaps, and improve overall sealing. The extrusion protrusion 26 in the middle of the bottom of the cover plate 13 applies a certain pressure to the cover plate 13 after installation, which on the one hand makes it more stable and reduces the shaking of the base 3, and on the other hand, the applied pressure makes the first sealing ring 15 and the second sealing ring 17 fit more tightly, enhancing the sealing effect.

[0028] Taking the installation and application of an underwater landscape lighting and positioning system in a marine cultural tourism scenic area as an example, the working principle of this underwater visible light fixing device is explained in detail.

[0029] The underwater landscape area of ​​this scenic spot is approximately 5-8 meters deep, with an average current speed of 0.5 meters per second, and features complex underwater topography, including some reefs and coral reefs. To ensure the safety of visitors and facilitate the illumination of the underwater landscape, it is necessary to install fixed underwater visible light devices.

[0030] Device Installation: First, select appropriate specifications of fixing bolts based on the actual conditions of the installation location. Since the base 1 is circular with multiple fixing holes 11 arranged in a ring, it can be flexibly installed on an underwater platform or reef surface. In this embodiment, stainless steel bolts with a diameter of 8 mm are used to fix the base 1 to a relatively flat underwater reef platform through the fixing holes 11. Tighten the bolts with an electric screwdriver to ensure the base 1 is firmly attached to the mounting surface. This increased contact area of ​​the circular base 1 and the evenly distributed fixing holes 11 ensure a uniform center of gravity distribution underwater, effectively resisting water flow impact and preventing swaying.

[0031] Connecting rod 2 is made of steel reinforcement, and its surface is coated with zinc-based anti-corrosion paint to effectively prevent rust. The lower end of connecting rod 2 is welded to the middle of the base 1, ensuring verticality and firmness during welding to allow it to withstand the weight of the device underwater as well as external forces such as water flow and pressure. The upper end of connecting rod 2 is fixedly connected to the base 3, also using welding, to ensure reliable connection.

[0032] Install the lamp holder 5 of the visible light positioning light 4 onto the base 3. The base 3 has a connecting cavity 12 inside, and the lamp holder 5 is threadedly connected to the connecting cavity 12. During installation, the worker aligns the lamp holder 5 with the threaded opening of the connecting cavity 12 and rotates the lamp holder 5 clockwise by hand or with a simple wrench to ensure a tight connection with the base 3. This threaded connection method facilitates subsequent disassembly, repair, or replacement of the visible light positioning light 4.

[0033] Internal component installation and sealing: The ring light source 8 and other necessary electronic components are installed in the mounting cavity 7 inside the lamp holder 5. After installation, a sealing process is performed: First, the first sealing ring 15 is installed in the annular groove 14 of the cover plate 13, ensuring the sealing ring is installed flat and without twisting. Then, the second sealing ring 17 is installed in the mounting groove 19 at the side wall end of the lamp holder 5. The second sealing ring 17 is L-shaped, with its first locking block 21 on its vertical surface precisely engaging with the first locking slot 20 on the side wall of the mounting groove 19. The end of the inner groove wall of the mounting groove 19 is engaged between the vertical surface of the second sealing ring 17 and the pressing part 22. This structure ensures that the second sealing ring 17 is securely installed and is not easily displaced or detached under underwater pressure and water flow impact. Next, the first protrusion 18 on the second sealing ring 17 is embedded into the first embedding groove 16 of the first sealing ring 15 to further enhance the sealing effect and effectively prevent moisture from penetrating into the mounting cavity 7. The latching groove 23 extending from the lower side of the mounting groove 19 cooperates with the second latching block 25 on the cover plate 13 to install the cover plate 13 at the lower end of the lamp holder 5, further reinforcing the connection between the cover plate 13 and the lamp holder 5, reducing gaps, and improving overall sealing performance. Finally, the extrusion protrusion 26 in the middle of the bottom of the cover plate 13 applies a certain pressure to the cover plate 13 after installation, making the first sealing ring 15 and the second sealing ring 17 fit more tightly, further ensuring sealing performance.

[0034] A photosensitive camera 10 is mounted on the truncated pyramid 9 located in the middle of the annular light source 8 at the upper end of the lamp holder 5. During installation, a dedicated mounting bracket and screws are used to fix the photosensitive camera 10 to the upper end of the pyramid 9, ensuring that the camera's shooting angle meets the monitoring needs of the surrounding underwater environment.

[0035] Operating Process: After installation and power connection, the ring light source 8 begins operation, emitting short-wave blue light. This blue light propagates underwater, providing illumination for the underwater landscape and serving as a positioning signal. The photosensitive camera 10 can be used to receive customer check-in information and transmit it to the backend. Throughout the entire operation, the double-sealed structure effectively protects the electronic components inside the lamp holder 5. Even in complex underwater environments, moisture is difficult to penetrate into the mounting cavity 7, ensuring the normal operation of the device. Simultaneously, the steel-reinforced connecting rod 2 and the robust chassis 1 structure allow the device to be stably fixed underwater, resisting water flow impact and pressure, ensuring the normal operation of the ring light source 8 and the photosensitive camera 10.

[0036] As can be seen from the above embodiments, this underwater visible light fixing device can effectively improve the stability and reliability in the underwater environment in practical applications. Its good sealing performance also ensures the normal operation of internal components, meeting the actual needs of underwater scenarios such as marine cultural tourism scenic spots.
