Underwater magnetic vacuum box

Technical Field

The utility model belongs to the technical field of boats and ships repair under water and specifically relates to a magnetism formula vacuum box under water is repaired auxiliary fixtures field under water to boats and ships.

Background

In the ship building process, due to the relative shortage of dock resources, the docking time is reduced as much as possible in the whole ship building period. However, as ships become larger and the environmental protection requirement becomes higher, the division and the requirement of the cabin become finer. Therefore, outfitting and coating work of all cabins cannot be finished in the dock, much work needs to be completed after launching, and the bottom planking can be damaged in the process.

Once the underwater outer plate is damaged, the front and back sides of the underwater outer plate cannot be provided with water due to the process requirement of electric welding, but the outer plate cannot be isolated from water, so that the traditional repairing method is to repair the underwater outer plate after the underwater outer plate is undocked from the water contact. The docking repair scheme is difficult to reserve, expensive, time-consuming and labor-consuming. And if the common vacuum box is adopted, because no force application point exists underwater, the vacuum box can not be adsorbed on the outer plate, and can not form vacuum and can not be isolated from water.

The technical scheme is as follows:

an underwater magnetic vacuum box comprises a cover plate, a clamping groove, a magnet, a flat strip, an eraser and a water pumping hole, wherein the length of the flat strip is larger than the width of the cover plate, the flat strip is fixed at the top of the cover plate through the clamping groove, and the magnet is fixed below the position, extending out of the cover plate, of the flat strip; the rubber is fixed below the side edge of the cover plate, the bottom horizontal plane of the rubber is lower than that of the magnet, and the rubber is compressed to realize watertight effect when the magnet adsorbs the hull outer plate; the water pumping hole is arranged on the cover plate and used for connecting a hose to pump water.

Preferably, the cover plate further comprises 4 press strips which are fixed on four sides of the cover plate.

Preferably, the cover plate further comprises 2 reinforcing ribs which are fixed on the center line of the cover plate in a cross mode.

Preferably, it further comprises a handle disposed on top of the cover plate.

Preferably, the number of the flat strips is 2, each flat strip is fixed at the top of the cover plate through 2 clamping grooves, and two ends of each flat strip are respectively provided with 1 magnet.

Preferably, the hose is connected with a water suction pump, and water in the vacuum box is pumped out through the hose by the power of the water suction pump.

Preferably, the magnet is a magnet with a switch.

Preferably, the water pumping hole is a threaded hole.

The beneficial effects of the utility model

1. The utility model discloses a frock principle is simple, compact structure, convenient operation, labour saving and time saving.

2. Use this utility model later just can carry out planking repair work under water and need not the secondary and advance the depressed place, will save the cost of advancing the depressed place of big pen and avoid advancing other risks of undocking. According to incomplete statistics, the cost of the ship for one-time docking and undocking is as follows: the tug costs 2 ten thousand per 3 times 2 times 12 ten thousand, the dock rent 10 ten thousand per day 6 days 60 ten thousand, i.e. without involving labor and other costs, the costs associated with equipment and facilities alone can be as high as 72 ten thousand.

3. Can be used for a plurality of times, and is also suitable for the outer plate area needing to be leaned against for vacuumizing in the building process.

4. The vacuum box with various specifications can be manufactured according to the repair requirement.

Detailed Description

The present invention will be further explained with reference to the following examples, but the scope of the present invention is not limited thereto:

with reference to fig. 1-5, an underwater magnetic vacuum box comprises a cover plate 1, a clamping groove 4, a magnet 6 (a magnet with a switch), a flat strip 7, an eraser 8 and a water pumping hole 9 (a threaded hole), wherein the length of the flat strip 7 is greater than the width of the cover plate 1, the flat strip 7 is fixed at the top of the cover plate 1 through the clamping groove 4, and the magnet 6 is fixed below the position where the flat strip 7 extends out of the cover plate 1; the rubber 8 is fixed below the side edge of the cover plate 1, the bottom horizontal plane of the rubber 8 is lower than that of the magnet 6, and the rubber 8 is compressed to realize watertight effect when the magnet 6 adsorbs the hull plate; the water pumping hole 9 is arranged on the cover plate 1 and used for connecting a hose to pump water.

The novel cover plate is characterized by further comprising 4 pressing strips 2, wherein the pressing strips 2 are fixed on the four sides of the cover plate 1.

It still includes strengthening rib 3, strengthening rib 3 is 2, is the crisscross central line position of fixing at apron 1.

It also comprises a handle 5, said handle 5 being arranged on top of the cover plate 1.

The flat strips 7 are 2, each flat strip is fixed at the top of the cover plate 1 through 2 clamping grooves 4, and two ends of each flat strip 7 are respectively provided with 1 magnet 6.

The hose is connected with a water pump, and water in the vacuum box is pumped by the water pump through the hose.

In a preferred embodiment, the clamping groove 4, the reinforcing rib 3, the cover plate 1, the pressing strip 2 and the handle 5 are all made of glass fiber reinforced plastic. And strong glue is adopted for bonding between the pressing strip 2 and the cover plate 1, between the reinforcing ribs 3 and the cover plate 1, between the clamping grooves 4 and the cover plate 1 and between the handle 5 and the cover plate 1. Screw holes are formed in the flat strip 7, and the magnet 6 with the switch is fixed on the flat strip 7 through bolts.

The using method comprises the following steps: after finding the outer panel position that needs and water isolated under water, detain this vacuum box's apron 1 on the planking and hold up the back, open the switch release magnetic force of four magnets 6, just fix whole box body on the planking through four draw-in grooves 4 and two band iron strips 7. Because the size of the key part is accurately calculated according to the size of each part (the bottom horizontal plane of the rubber 8 is lower than that of the magnet 6), the rubber 8 can be compressed by the adsorption of the magnet 6 to play a watertight role. And then the water pump on the shore is opened, water in the vacuum box is pumped through the hose, finally, the water in the vacuum box is pumped out completely, and the rubber is watertight, so that external water cannot enter, the purpose of vacuum isolation from water is achieved, and the repair (internal welding, single-side welding and double-side forming) of the outer plate is facilitated.
