Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dropping and lifting system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-dropping and lifting system, and more particularly, to a water-dropping and lifting system capable of dropping objects such as underwater in any direction and point spaced from a ship, To a direction and inclination adjustable underwater delivery and lifting system which is not detached from the boom stand when the turntable is in use and can be very convenient and easy to adjust the orientation of the column by the turntable.

Fish can be classified into light-sensitive fishes that follow light in response to light and non-fishes that do not follow light well. They are used to catch fishes such as squid, anchovies, mackerel, horse mackerel, Generally, a fishing light is used when fishing. A headlight is a device for gathering meat with light, and is classified into an aquarium fish used in the sea and an underwater fish used for submerging in water. In the case of a water hammer, there is a problem that a large amount of power generation equipment is required because a lot of lighting equipment must be used in order to make the light of the aquarium reach deep water. Therefore, the use of an underwater pick-up light can reduce the number of pick-up lights and is more effective in picking.

In addition, if a diver enters underwater and conducts underwater work, it is a common practice to have individual divers enter the headlamp with their head on their heads. However, when an ocean exploration work or an overturning of a large ship occurs, Individual headlamps are also useful for rescue operations, but it may be more efficient to drop the underwater work lights into a certain area.

Underwater lamps, such as pick-up lamps and work lights, which are normally used by dropping in water, have built-in electric wires for power supply and use cables with metal wire wires to prevent cutting of electric wires. Because of their long and heavy length, A winch is needed to untie and wind the cable connected to the cable. However, in the conventional winch, there is a problem that it is inconvenient to use because the operator simply connects the pulley for unwinding and winding the cable to the drive motor to manually adjust the operation of unwinding and winding the winch.

In order to know the depth of the underwater light, the length of the cable in the water is directly checked by eye, and the approximate depth of the water is estimated by the length of the cable in the water. The depth of water underwater can not be estimated accurately because it is often pushed by submarine algae rather than only vertically. In addition, even if a part of the cable is twisted or folded and can not pass through the pulley in the operation of loosening or winding the cable, the driving motor is forced to operate, so that the driving motor becomes unreasonable, .

In order to solve such a problem, a technique that has emerged is a technology such as patent registration No. 497783 entitled " winch for underwater pick-up lamp and control method thereof " The operation of the winch is controlled by the control system to automatically correct the water depth of the underwater, and the operator is able to check the underwater condition and the degree of catch.

However, the above patent has the following problems.

First, there is a problem that it is not possible to drop the underwater dropping point at a distance from the ship at a certain distance in the lateral direction because the cable is directly dropped into the water after passing through the pulley of the winch fixed on the deck of the ship.

Secondly, when the operator is not careful when the cable is rolled up, there is a problem that the cable is over-wound and the underwater lamp attached to the end of the cable collides with the pulley,

Third, there is a problem that excessive power is needed to drive the winch because the winch has to bear the weight of the cable because the winch does not have a roller (pulley) that acts as a movable pulley.

In order to solve the above-mentioned problems, the applicant of the present invention (inventor) has developed and applied the patent application No. 2014-77196, " Water Underwater Drop Delivery System "
