Description

[Detailed description of the invention] (Industrial application field) This invention is used for temporary equipment used for ship construction or repair work in docks, such as welding power supplies, lighting lights, telephone sets, etc. Concerning the storage structure for applicable working equipment in the dock.

(Prior art) Traditionally, temporary equipment used for work inside the dock, such as non-submersible equipment such as welding power supplies and lighting lights, has been repeatedly brought into the dock and temporarily installed and removed every time water is poured into the dock. .

In addition, in order to eliminate this inconvenience, lighting lights are also installed in a suitable location on the inside wall of the dock.

(Problems that the invention aims to solve) However, as mentioned above, temporary equipment used for work inside the dock is repeatedly brought into the dock for temporary installation.
Removal of the equipment causes significant damage, and it requires a great deal of labor and time to temporarily erect it inside the dock and to store it after removing it outside the dock.

On the other hand, when lighting lights are installed in a suitable place on the inside wall of the dock, a light-transmitting plate such as glass is installed in front of the light, so various objects are exposed to this light-transmitting plate during work inside the dock. The board is often damaged by hitting the board, and what's more, the packing that is placed around the transparent board to make it watertight becomes damaged over time during repeated pouring and draining in the dock. This causes corrosion, and when water is poured into the dock, seawater enters the dock and has a negative impact on the light itself.

Additionally, if the lighting is installed in a closed type, the heat generated by the lighting will increase the temperature within the compartment.
There was also a problem that the lighting, watertight packing, and translucent panels were adversely affected, and in order to solve this problem, it was necessary to forcibly ventilate the storage compartment using ventilation fans, etc.

(Means for Solving the Problems) This invention was devised in view of the above points, and incorporates a subcase whose upper part is sealed against the inner wall of the dock and which is opened to the outside at the lower part. To provide an in-dock working equipment storage device that allows seawater to freely enter and exit a subcase, but does not have any adverse effect on temporary equipment stored in the subcase.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

FIG. 1 is a schematic side view showing the main parts of this invention, FIG. 2 is a front view of the same, and FIG. 3 is a side view when water is being poured into the dock.

In the figure, 1 is a dock, 2 is a submarine built into a side wall 3 of the dock, the front of which is covered by a hanging wall 4 continuous with the side wall 3 of the dock, and an opening 5 to the outside at the bottom.

Reference numeral 6 denotes guide bars installed upright within the submersible box 2, which are arranged in pairs on the left and right at appropriate intervals. 7 is the guide bar 6
A guide bar 6 is loosely inserted into an annular body 8 provided on the side surface of the float. In addition, instead of this guide bar 6, various guide means can be considered.

Reference numeral 9 denotes temporary equipment mounted on the float 7, and in the illustrated example, a lighting lamp is used.

In the figure, 10 indicates the bottom of the dock, and 11 indicates seawater when water is injected into the dock.

(effect) The operation of the above configuration will now be explained.

When the lighting lamp 9 is mounted on the float 7 as in the embodiment, when the inside of the dock 1 is drained and the float 7 is at its lowest position, the lighting lamp 9 faces the opening 5, and from this the work place in the dock is exposed. It is in a position where it can illuminate the

However, when the work in the dock is completed and water is injected into the dock, seawater 11 enters the submersible 2 through the opening 5, but the float 7 rises to the water surface 11a.
It rises along the guide bar 6.

Eventually, after the opening 5 is submerged in the water, a sealed space 2a is formed in the upper part of the submersible, and the float 7 floats to the water surface 11a in this sealed space 2a.When the water injection into the dock is completed, the sealed space 2a is formed. When the internal pressure of the vessel and the water head pressure within the dock are balanced, the lighting lamp 9 is stored under the condition that an appropriate gap is maintained between the ceiling of the submersible and the interior of the submersible.

In the embodiment, the illuminating lamp 9 is mounted on the float 7, and the illuminating lamp 9 is used exposed on the float 7, and the illuminating lamp 9 is used and stored as it is, but the welding power source etc. The light may be mounted inside the float having an open structure, and the illumination light may also be stored inside the float when not in use and exposed outside the float only when in use.

In short, the temporary equipment mounted on the float is not submerged in water when stored, but is stored in the sealed space formed inside the subcase via the float.

(Effects of the invention) As described above, this invention incorporates a subcase with an external opening at the bottom inside the inner wall of the dock, and a guide means is set up in the subcase so that it can be moved up and down along the guide means. A float is attached, and non-submerged temporary equipment used for work inside the dock is mounted on the float.When water is injected into the dock, the float is floated to the water surface in the sealed space formed at the top of the submersible. Temporary equipment was stored there, and when draining water from inside the dock, a float was lowered to the bottom of the box and the equipment mounted on it was immediately accessed through the opening. There is no need to carry equipment into the dock every time water is poured into the dock, and repeat temporary installation and removal work. Therefore, the service life of the equipment is extended without damaging it. The equipment stored in the box becomes ready for use immediately, which improves work efficiency.Furthermore, workers can freely enter and exit the box through the opening, making it extremely convenient to handle the equipment. The effects of this are enormous.
