Description

Technical Field

[0001] This application belongs to the field of marine equipment technology, specifically relating to a UV lamp device suitable for underwater biofouling prevention. Background Technology

[0002] Biofouling is a serious problem for various observation equipment deployed in seawater for extended periods. Biofouling can cause signal drift and data errors, and make it difficult for underwater cameras to acquire clear images. Furthermore, biofouling can affect the heat dissipation and hydrodynamic flow of marine observation equipment, and cause additional corrosion to mechanical structures.

[0003] Traditional antifouling technologies include various methods such as mechanical, physical, and chemical methods, such as mechanical scraping and applying antifouling coatings. Mechanical scraping is not effective at cleaning the surface of spherical equipment, and its effectiveness decreases when the brush bristles deform or the gap between the bristles and the equipment surface increases. Antifouling coatings contain harmful substances that damage the marine environment and the safety of other marine life, and are not suitable for coating the optical lenses of monitoring instruments.

[0004] Existing anti-biofouling devices often require removal from the water surface for installation, maintenance, or replacement, resulting in long maintenance times and high costs. Utility Model Content

It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solution of this application, rather than limitations thereof. Specific technical features can be combined with each other.

[0023] See Figure 1 A UV lamp device suitable for underwater biofouling prevention includes a waterproof housing 1, a lamp bead assembly 2, a circuit board assembly 3, and a control device (not shown in the figure). The lamp bead assembly 2 and the circuit board assembly 3 are sealed inside the waterproof housing 1, and the control device 4 is located at a shore-based control center.

[0024] The waterproof housing 1 is made of high-strength corrosion-resistant material and includes a glass cover 11, a sealed outer shell 12, a first sealing ring 13, a second sealing ring 14, a threaded sleeve 15, and an end cap 16.

[0025] The glass cover 11 is made of quartz glass, which has high light transmittance and good chemical stability, and features a flange design at the opening. The front end of the sealing shell 12 is designed with external threads, and the glass cover 11 and the sealing shell 12 are securely fixed by the threaded sleeve 15. Sealing ring grooves are designed on the front end face and the top boss of the sealing shell 12, achieving a waterproof seal between the glass cover 11 and the sealing shell 12 through the first sealing ring 13 and the second sealing ring 14. The first sealing ring 13 forms an axial seal through compression between the sealing ring groove on the front end face of the sealing shell 12 and the flange face of the glass cover 11, while the second sealing ring 14 forms a radial seal through compression between the sealing ring groove on the top boss of the sealing shell 12 and the inner wall of the glass cover 11.

[0026] See Figure 2The end cap 16 is provided with a third sealing ring 161, which achieves a waterproof seal between the sealing shell 12 and the end cap 16. Screws 162 are installed on the end cap, securely connecting the sealing shell 12 and the end cap 16. A connector 163, specifically an underwater wet-plug connector, is installed inside the end cap 16. A matching underwater wet-plug connector can be installed on the base of the marine observation equipment to integrate the UV lamp into the monitoring instrument. The underwater wet-plug connector 163 supports underwater plug-and-play replacement of the UV lamp without bringing it to the surface.

[0027] See Figure 4 Alternatively, a watertight cable 164 can be installed at the tail of the end cap, and can be independently installed on the outside of the marine testing instrument. The underwater wet-plug connector 163 and the watertight cable 164 are used for power supply to the UV lamp and data signal transmission.

[0028] See Figure 2 The end cap 16 is provided with a locking nut 164 and a fourth sealing ring 165 at its tail end. The locking nut 164 is used to connect and fasten the UV lamp to the base of the marine observation equipment, and the fourth sealing ring 165 achieves waterproof sealing between the UV lamp and the base of the marine observation equipment.

[0029] See Figure 3 The LED assembly 2 is installed inside the glass cover 11 and includes a mounting post 21, UV LEDs 22, and set screws 23. The mounting post 21 has an integrated design with eight UV LED holes arranged in a double spiral around its perimeter, ensuring 360° illumination without blind spots. The arrangement and number of LED holes can also be customized according to actual needs. The UV LEDs 22 are mounted to these holes with screws. The mounting post 21 has a through hole in its center, through which the UV LEDs 22's wiring passes and connects to the circuit board assembly 3. The mounting post 21 is secured to the front end of the sealed outer shell 12 by set screws 23 on its side.

[0030] The circuit board assembly 3 is installed inside the sealed housing 12. The control device includes a handheld device, a computer, or a server, etc. The control device can control the light intensity and irradiation time of the UV lamp through the circuit board assembly 3 to obtain a better anti-biofouling effect and a longer UV lamp lifespan. It can also monitor the current and voltage of the UV lamp and replace and maintain the UV lamp in a timely manner if there are any problems.

[0031] The specific working process of this utility model is as follows:

[0032] like Figure 4As shown, when integrating a UV lamp into the base of a marine observation equipment, a hole needs to be pre-drilled in the base, and a matching wet-plug connector needs to be installed inside the hole. During connection, insert the tail end of the UV lamp end cap into the base hole, simultaneously aligning the connector inside the tail end with the connector in the base hole. Tighten the locking nut at the tail end; installation is convenient. The UV lamp's light intensity and irradiation time can be adjusted via a remote control device, and the UV lamp's current and voltage can be monitored. Problematic UV lamps can be replaced and maintained promptly. Replacement and maintenance only require removing the original UV lamp and replacing it with a new one; there is no need to disassemble the entire marine observation instrument and remove it from the water. If the UV lamp is installed separately, a separate fixture can be designed and installed at an appropriate location on the marine observation equipment.

[0033] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
