Description

SUBSTANCE: invention relates to the field of lighting means for underwater technical works, in particular, to underwater lamps.

Known autonomous underwater lamp ASP-74 "Malachite", included in the set of equipment for divers for underwater technical work. The luminaire includes a battery and a switch, which are attached to the waist belt, and the actual luminaire with a reflector and a 6 V lamp, placed on the helmet. [1] However, this type of lantern does not provide a wide light field, has a sufficiently large weight for a diver (about 14 kg), and is not intended for underwater technical work at great depths.

Also known are underwater lamps for divers, powered by a cable from a power source located on the surface, for example on board a ship. These underwater lamps include UOG-66 and Shtepsel-12D, which include a power supply unit, a coil with a power cable, a lamp itself (portable and stationary), a coil with a cable for a portable lamp (for a length of up to 50 m), a stand for fixing a stationary luminaire on the ground. [2]

A significant design drawback of these underwater luminaires: large equipment, significant weight and size characteristics (about 300 kg), as well as a rigid connection to power from the surface via a cable.

Known autonomous deep-sea lamp, which includes a body floating on the surface with solar batteries, equipped with an anchor with a cable to hold above the bottom at the desired point and lowered on the cable to the bottom of the lamp in a sealed sheath. At the same time, buoyancy, being held at an underwater anchor, can drift along the surface under the influence of wind and current. [3]

Significant disadvantages of the prototype are the impossibility of accurately holding the lamp lowered to the bottom at the point of location of the survey object due to the distance (depth) from surface buoyancy, the possibility of entanglement of the cable of the underwater lamp with a cable, the bulkiness of the entire structure, especially for conditions of great depth, the danger of breaking the cable line on excitement, as well as dependence of sustainable nutrition on the weather.

The objective of the proposed invention is to improve the lighting conditions of the place of underwater work at great depths.

The problem is solved by the fact that in a well-known deep-sea lamp containing buoyancy, batteries, an anchor, an LED lamp enclosed in a sealed housing, the lamp housing is placed in buoyancy, the anchor is connected to the lamp housing with a short cable, and a lithium-ion battery is hermetically placed inside the housing, when At the same time, in the upper part of the buoyancy, equipped with a transport eyelet, the antenna of the hydroacoustic starter is fixed, which is tuned to the code frequency of the sonar station of the underwater vehicle, and the starter is included in an electrical circuit with a battery and a lamp.

New distinctive features of the self-contained deep-sea luminaire are:

- placement of the battery inside the buoyancy;

- the presence of an acoustic starter antenna on the buoyancy;

- connection of the armature to the buoyancy body with a short cable to keep the lamp close to the bottom;

- installation of an eyelet on the buoyancy hull.

These distinctive features provide: compact design of the luminaire and its prompt delivery to a given point by the device itself, stable placement of the luminaire (without drift) near the object and energy savings of the underwater vehicle. The luminaire can be used, when switched on, as a driving light beacon for the apparatus.

A diagram of the design of a self-contained deep-sea luminaire is shown in Fig. 1

In the upper part of the buoyancy from the syntactic 1 there is an antenna of the hydroacoustic starter 2. The buoyancy body is equipped with a transport eye 3 for the manipulator of the apparatus. Lithium-ion batteries 4 and LED lamps (type LED) 5 are hermetically integrated into the buoyancy hull. The luminaire is attached with a cable 6 to the bottom anchor 7 installed near the object 8. A hydroacoustic station with a radiating antenna 10 is located on the underwater vehicle 9.

The device works as follows:

The underwater vehicle next to the detected object anchors a deep-sea lamp, which, thanks to a powerful lithium-ion battery, can be repeatedly used to illuminate the area of underwater technical work. Being near an object with a deep-sea lamp installed nearby, or returning again after recharging, the device emits a code message from the antenna, which switches the acoustic starter, placed on buoyancy, to turn on the LED lamps. In the illuminated area with a luminaire, the apparatus examines the sunken object from different angles, performs the necessary work. The deep-sea luminaire can also be used as a driving light beacon, having turned it on with an acoustic signal in advance before approaching the object area.

The technical and economic advantage of the proposed autonomous deep-sea luminaire in comparison with the prototype [3] is that it allows efficient performance of underwater technical work at the facility by an underwater vehicle in an additionally illuminated working area, while increasing the safety of the vehicle, and can also serve as a drive light beacon for access to the object at great depths.
