Description

Technical Field

[0001] This utility model relates to the field of underwater operation auxiliary equipment technology, and in particular to an underwater camera and lighting integrated machine that is resistant to water flow impact. Background Technology

[0002] In fields such as marine exploration and underwater engineering monitoring, underwater camera lighting equipment is an indispensable auxiliary tool. Underwater camera lighting equipment needs to dive into deep water areas and face complex and ever-changing hydrological environments. Especially in water environments with rapid currents or turbulent currents, underwater camera lighting equipment needs to maintain extremely high structural stability to ensure the clarity of the captured images and the continuity of lighting operations.

[0003] However, in existing technologies, the internal structure design of conventional underwater camera and lighting integrated machines is not compact enough. In particular, for the installation of large-capacity batteries or capacitors and other large-weight power components, existing technologies only use simple slots or adhesives for fixing. This traditional fixing method is difficult to effectively resist the huge inertial impact force generated when external water flow impacts the cylinder.

[0004] When an underwater camera and lighting unit encounters severe water flow or accidental collisions during operation, the relatively heavy power supply components inside the cylinder are prone to relative displacement or high-frequency shaking. This instability of internal components can easily lead to loosening of the connection lines between the power supply components and the circuit board, causing power outages. Furthermore, continuous vibration and collisions can cause physical damage to the internal precision electronic components, thus severely limiting the service life and operational reliability of the underwater camera and lighting unit in turbulent water environments.

[0005] Therefore, this utility model proposes an underwater camera and lighting integrated machine that is resistant to water flow impact in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] In existing technologies, conventional underwater camera and lighting integrated cameras are prone to relative displacement or high-frequency shaking of the relatively large power supply components inside the cylinder when encountering strong currents or accidental collisions. This instability not only easily leads to loosening of the connection lines between the power supply components and the circuit board, causing power outages, but also the existing bottom sealing structure often requires complete disassembly to replace the power supply, resulting in cumbersome maintenance. This utility model aims to provide an underwater camera and lighting integrated camera with an improved structure that can effectively solve the above problems and resist water flow impact.

[0007] This utility model provides an underwater camera and lighting integrated device resistant to water flow impact, including a cylindrical body and an end cap threaded to the opening at the top of the cylindrical body. A lamp head is threaded to the center of the end cap. A circuit board is installed inside the cylindrical body, and a capacitor is fixedly connected to the bottom of the circuit board. A fixing pad is fixedly installed on the lower end of the inner wall of the cylindrical body, and a fixing seat is fixedly connected to the lower end of the fixing pad. The fixing pad and the fixing seat cooperate to restrict the position of the capacitor. A bottom cover is threaded to the bottom of the cylindrical body, and an installation port is threaded to the center of the fixing seat.

[0008] Preferably, an annular groove is provided on the outer edge of the lower end of the end cap, and a sealing ring is installed in the annular groove. The sealing ring is pressed against the upper end of the inner wall of the cylinder to seal the connection between the end cap and the cylinder.

[0009] Preferably, a rubber ring is provided between the lamp holder and the end cap. The rubber ring is fitted onto the outer wall of the lamp holder and pressed between the lamp holder and the end cap to provide a tight and waterproof seal.

[0010] Preferably, an isolation cover is installed below the end cover, the isolation cover is located between the circuit board and the end cover, and the outer edge of the isolation cover is fixedly connected to the inner wall of the end cover.

[0011] Preferably, the bottom of the isolation cover has a connection port, and the output line at the top of the circuit board passes through the connection port and extends to the top of the isolation cover to achieve an electrical connection with the bottom of the lamp holder.

[0012] Preferably, an annular sealing groove is provided on the bottom end face of the cylinder, and a sealing ring is embedded inside the sealing groove. The sealing ring is compressed and deformed when the bottom cover is tightened to achieve a seal at the bottom of the cylinder.

[0013] Preferably, the center of the upper surface of the bottom cover is fixedly connected to the bottom of the fixing seat, and the outer edge of the bottom cover is threaded to the inner wall of the bottom end of the cylinder, thereby locking the fixing seat inside the cylinder.

[0014] Preferably, the fixing pad is arranged around the inner circumference of the cylinder, the upper surface of the fixing seat abuts against the bottom surface of the fixing pad, and the fixing seat has a disc-shaped structure to support the capacitor.

[0015] Preferably, the mounting port is constructed as a sealing plug with external threads. The mounting port is screwed into the threaded hole in the center of the mounting base and forms a channel for capacitor replacement when the mounting port is unscrewed.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing underwater camera lighting equipment is prone to power supply interruption and component damage when encountering strong current impact by setting a limiting structure composed of a fixing pad and a fixing seat inside the cylinder. The fixing pad is arranged around the inner wall of the cylinder and the fixing seat supports the bottom of the capacitor. This achieves the effect of stable physical limiting of internal components, effectively absorbing and resisting the vibration generated by water flow impact, and ensuring stable operation of the equipment in harsh underwater environments.

[0017] 2. This utility model solves the problem in the prior art that when replacing the internal power supply of underwater equipment, it is often necessary to completely disassemble the bottom sealing structure, which leads to complicated operation and easy wear of the sealing parts. This is achieved by ensuring the high-level sealing performance of the bottom while realizing the rapid replacement of the capacitor, greatly improving the equipment's endurance and reducing daily maintenance losses.

[0018] 3. This utility model solves the problem of leakage that easily occurs in conventional underwater equipment under deep water pressure or dynamic water flow, which leads to short circuit and burnout of the internal circuit board. It achieves the effect of building a comprehensive waterproof barrier, ensuring that the inside of the cylinder is always dry, and improving the safety and reliability of the camera lighting components.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 6 This utility model provides an underwater camera and lighting integrated device that is resistant to water flow impact. It aims to solve the problems of existing underwater equipment where the internal power supply components are prone to shaking and causing power outages when facing strong currents, as well as the cumbersome disassembly and assembly of the bottom sealing and maintenance structure.

[0023] Please refer to Figure 1 and Figure 2 The underwater camera and lighting unit resistant to water flow impact includes a cylindrical body 1 as the main shell structure and a quick-release mechanism 2 installed in the bottom area of ​​the cylindrical body 1. The cylindrical body 1 has a cavity inside for installing electronic components, and the quick-release mechanism 2 is used to physically limit and seal the internal components from the bottom.

[0024] Specifically, an end cap 201 is threadedly connected to the top opening of the cylinder 1. A threaded interface is provided at the center of the end cap 201 and a lamp head 204 is threadedly connected to it. The lamp head 204 serves as a camera lighting component, integrating lighting beads and a camera. Part of the structure extends above the end cap 201 for underwater operations. To ensure the sealing of the top, an annular groove is provided on the lower outer edge of the end cap 201. A sealing ring 202 is installed in the annular groove. When the end cap 201 is tightened on the top of the cylinder 1, the sealing ring 202 presses against the upper end face of the inner wall of the cylinder 1, thereby effectively preventing water from seeping in through the threaded gaps.

[0025] Furthermore, to enhance protection at the interface, a rubber ring is provided between the lamp holder 204 and the end cover 201. The rubber ring is tightly fitted onto the outer wall of the lamp holder 204 and pressed against the contact surface between the lamp holder 204 and the end cover 201, providing a secondary seal through the elastic deformation of the rubber material. An isolation cover 203 is installed in the space below the end cover 201. The isolation cover 203 is located between the circuit board 205 and the end cover 201, and the outer edge of the isolation cover 203 is fixedly connected to the inner side wall of the end cover 201, thereby isolating the mechanical connection structure at the top from the electronic component compartment below.

[0026] A circuit board 205 is installed inside the cylinder 1. A capacitor 206 is fixedly connected to the bottom of the circuit board 205. The capacitor 206 serves as the energy storage and power supply unit of the device to provide power to the device. In order to realize the conduction between the circuit board 205 and the top lamp head 204, a connection port 212 is opened at the center of the bottom of the isolation cover 203. The output wire at the top of the circuit board 205 passes through the connection port 212 and extends to the top of the isolation cover 203 to achieve electrical connection with the bottom of the lamp head 204, thereby forming a complete power supply and control circuit.

[0027] Please refer to Figure 2 , Figure 4 as well as Figure 6 The fixing pad 207 is installed on the lower end of the inner wall of the cylinder 1. The fixing pad 207 is arranged around the inner circumference of the cylinder 1 and is tightly attached to the inner wall surface of the cylinder 1. The fixing pad 207 is fixedly connected to the inner wall of the cylinder 1 by bonding or interference fit, and serves as a buffer medium between the internal components and the rigid outer shell of the cylinder 1. The fixing seat 208 is fixedly connected to the lower end of the fixing pad 207. The upper edge of the fixing seat 208 abuts against the bottom surface of the fixing pad 207. The fixing seat 208 has a plate-like or block-like structure and is laterally connected across the interior space of the cylinder 1. During this process, the fixing pad 207 and the fixing seat 208 work together to restrict the spatial position of the capacitor 206 inside the cylinder 1. Specifically, the capacitor 206 is located above the fixing seat 208 and is supported by the bottom of the fixing seat 208. At the same time, the fixing pad 207 restricts the radial displacement of the capacitor 206 in the lateral dimension, ensuring that the capacitor 206 will not deflect or tilt laterally inside the cylinder 1. This ensures the stability of the capacitor 206 and the reliability of the electrical connection between the capacitor 206 and the circuit board 205 above when facing the impact of external turbulent currents.

[0028] As a preferred embodiment, to ensure the sealing performance of the bottom of the cylinder 1 and prevent water from entering through the bottom gaps, please refer to... Figure 2 and Figure 6The bottom end face of the cylinder 1 is provided with an annular sealing groove 211. A sealing ring 202 is embedded in the sealing groove 211. The sealing ring 202 is made of elastic rubber material and is configured to fill the connection area between the bottom end face of the cylinder 1 and the upper surface of the bottom cover 209.

[0029] In a preferred embodiment, in order to achieve the sealing and compaction of the internal components, the bottom cover 209 is fixedly connected to the bottom of the fixing seat 208. The outer edge of the bottom cover 209 is provided with external threads, and the inner wall of the bottom end of the cylinder 1 is provided with internal threads. The bottom cover 209 is fixed to the bottom opening of the cylinder 1 by means of threaded connection. When the bottom cover 209 is rotated and tightened, the upper surface edge of the bottom cover 209 abuts against and presses against the sealing ring 202 located in the sealing groove 211. The sealing ring 202 undergoes elastic deformation under pressure and fills the sealing groove 211, thereby achieving complete sealing of the bottom of the cylinder 1. At the same time, the bottom cover 209 supports the internal components upward through the fixing seat 208 to prevent the internal parts of the cylinder 1 from axially moving during underwater operation.

[0030] As a preferred embodiment, in order to achieve quick replacement and maintenance of the internal power supply without disassembling the overall bottom cover 209, the mounting port 210 is constructed as a sealing plug structure with external threads. The mounting port 210 is threaded into the threaded hole in the center of the fixing seat 208. After the mounting port 210 is tightened, it seals the central area of ​​the bottom of the cylinder 1 and together with the bottom cover 209, forms a complete bottom sealing structure. When it is necessary to replace the capacitor 206, the operator unscrews the mounting port 210 by rotating it in the opposite direction. At this time, the through hole in the center of the fixing seat 208 is exposed, forming a channel for the capacitor 206 to enter and exit. This achieves an impact-resistant effect in water, while improving the service life of the instrument and reducing wear. Furthermore, the quick replacement of the capacitor 206 enables long-term continuous use.

[0031] As a preferred embodiment, the fixing pad 207, fixing seat 208, bottom cover 209 and mounting port 210 are combined to form the fixing quick-release mechanism 2. As an integral functional module, the fixing quick-release mechanism 2 not only ensures the stability of the capacitor 206 when facing the impact of the turbulent current inside the cylinder 1 through the physical limitation of the fixing pad 207 and fixing seat 208, but also provides a convenient maintenance method through the split threaded disassembly and assembly structure of the mounting port 210.

[0032] Working principle: First, the sealing rings 202 are installed on the lower outer edge of the end cap 201 and inside the sealing groove 211 at the bottom of the cylinder 1. Then, the end cap 201 is threaded and tightened to the top opening of the cylinder 1, so that the sealing rings 202 are press-fitted against the inner wall of the cylinder 1 to block the water flow at the top. At the same time, the lamp head 204 is threaded to the center of the end cap 201. The rubber ring between the lamp head 204 and the end cap 201 is deformed by pressure to achieve a seal at the interface. Then, the bottom cap 209 is threaded to the bottom of the cylinder 1. The bottom cap 209 is used to press the sealing rings 202 in the sealing groove 211 to achieve a bottom seal. Thus, a dry internal working environment is created through a multi-level sealing structure. During underwater operations, when the cylinder 1 shakes violently due to the impact of strong currents, the quick-release mechanism 2 located inside the cylinder 1 comes into play. The fixing pad 207 fits tightly against the inner wall of the cylinder 1, and the fixing seat 208 is connected below the fixing pad 207 and provides lateral support. The two work together to firmly restrict the capacitor 206 above the fixing seat 208 and in the central area of ​​the cylinder 1, effectively resisting the inertial force generated by the water flow impact, preventing the capacitor 206 from radially deflecting or axially moving, and ensuring that the capacitor 206 is always stably connected to the bottom of the circuit board 205, thereby ensuring that the circuit board 205 continuously supplies power and transmits signals to the lamp head 204 through the connection port 212. When capacitor 206 is depleted and needs to be replaced, the operator loosens and removes the mounting port 210, which is threaded to the center of the fixing base 208. At this time, the through hole is exposed in the center of the fixing base 208, and the old capacitor 206 slides out from the bottom of the cylinder 1 through the through hole. The operator pushes in the new capacitor 206 and resets it. Finally, the mounting port 210 is tightened again to seal the bottom of the cylinder 1. The independent installation and removal of the mounting port 210 does not require disassembling the bottom cover 209 or damaging the overall sealing structure, thus achieving quick power replacement and long-term operation.
