Description

Technical Field

[0001] The present invention relates to the technical field of ship maintenance, and specifically relates to an electric heating and drying device for ship maintenance. Background Art

[0002] A ship is an artificial means of transportation mainly operating in geographical waters. Its interior mainly includes a accommodation space, a support structure, and a drainage structure, and has a propulsion system that utilizes external or self - contained energy. When a ship is in normal use, it needs to be regularly maintained, inspected, and serviced to ensure the safety, performance, and service life of the ship. Ship maintenance mainly includes hull cleaning and anti - corrosion, mechanical equipment lubrication, painting and rust prevention treatment, regular inspection and maintenance, etc.;

[0003] During the ship maintenance process, an electric heating and drying device is required, which is mainly used for drying, preheating, and curing in the ship maintenance process. However, traditional electric heating and drying devices still have some problems when used for ship maintenance: the area and angle of the exhaust duct are relatively fixed and cannot be adjusted flexibly, which increases energy consumption for small - area maintenance. Secondly, the internal electromagnetic heating components are mostly fixedly installed in the equipment outer frame. When subsequent maintenance is required, the entire equipment outer frame needs to be disassembled for maintenance, which is rather troublesome.

[0045] Working principle: When in use, control to turn on the fan system 3 and the electromagnetic heating element 24 corresponding to the position of the sealing cylinder 27 in the electric heating mechanism 2. The air body is heated by the electromagnetic heating element 24 in the electric heating mechanism 2 and then discharged into the exhaust air mechanism 4;

[0046] Among them, in the initial state, the first exhaust air duct opening 451 is communicated with the first exhaust air through groove 441, the second exhaust air duct opening 452 is communicated with one of the second exhaust air through grooves 442, and the third exhaust air duct opening 453 is communicated with one of the third exhaust air through grooves 443.

[0047] By controlling to turn on the third motor 462 to drive the first gear 461 to drive the first tooth ring 46 to rotate, thereby controlling the control flow plate 44 to rotate in a sealed manner, so that the first exhaust air duct opening 451 is communicated with the first exhaust air through groove 441, the second exhaust air duct opening 452 is communicated with one of the second exhaust air through grooves 442, and the third exhaust air duct opening 453 corresponds to the second sealing block 445 (or the first exhaust air duct opening 451 is communicated with the first exhaust air through groove 441, the second exhaust air duct opening 452 corresponds to the first sealing block 444, and the third exhaust air duct opening 453 is communicated with one of the third exhaust air through grooves 443). The heat flow can be discharged through the first exhaust air duct opening 451, the second exhaust air duct opening 452 (or the first exhaust air duct opening 451, the third exhaust air duct opening 453) with a small area, so as to reduce the heating power and the power of the fan system 3 at this time to adapt to the electrothermal drying operation on a small area of ship repair parts;

[0048] Among them, by controlling to turn on the second motor 426 to drive the second shaft 424 to control the second gear 423 to drive the second tooth ring 422 to rotate, thereby controlling the connecting card tube 42 to rotate, and then adjusting the first exhaust air duct opening 451, the second exhaust air duct opening 452 and the third exhaust air duct opening 453 to rotate, so as to adjust the overall arrangement position of the first exhaust air duct opening 451, the second exhaust air duct opening 452 and the third exhaust air duct opening 453. When the first exhaust air duct opening 451, the second exhaust air duct opening 452 and the third exhaust air duct opening 453 are in a horizontal state, accurate electrothermal drying operation can be performed on the horizontally structured ship repair parts. When the first exhaust air duct opening 451, the second exhaust air duct opening 452 and the third exhaust air duct opening 453 are in a vertical state, accurate electrothermal drying operation can be performed on the vertically structured ship repair parts. When the first exhaust air duct opening 451, the second exhaust air duct opening 452 and the third exhaust air duct opening 453 are in an inclined state, accurate electrothermal drying operation can be performed on the inclined structured ship repair parts. When the first exhaust air duct opening 451, the second exhaust air duct opening 452 and the third exhaust air duct opening 453 are always rotating, accurate electrothermal drying operation can be performed on the circular structured ship repair parts;

[0049] When it is necessary to replace and seal the electromagnetic heating element 24 corresponding to the position of the sealing cylinder 27, first control the opening of the telescopic cylinders 263 on both sides to drive the corresponding sealing cylinder 27 to slide horizontally outside the air duct 26, facilitating the separation of the sealing cylinder 27 from the corresponding end of the heating outer cylinder 23;

[0050] At this time, drive the abutting block 2311 not to abut, and the spring 236 drives the plurality of positioning sliding frames 233 to move away from each other, and the other end of the electromagnetic heating element 24 loses its positioning;

[0051] Subsequently, control the opening of the first motor 224 to drive the driving worm 223 to drive the driven worm gear 222 to rotate, and then control the turning shaft 22 to drive the two storage racks 221 to rotate, thereby swapping the positions of the two electromagnetic heating elements 24. The new electromagnetic heating element 24 is placed between the two sealing cylinders 27, and the electromagnetic heating element 24 to be repaired is separated from the two sealing cylinders 27, facilitating the rapid maintenance of the electromagnetic heating element 24;

[0052] Subsequently, control the opening of the telescopic cylinders 263 on both sides again to drive the corresponding sealing cylinder 27 to slide horizontally outside the air duct 26, so that the sealing cylinder 27 is movably sleeved on the end of the corresponding heating outer cylinder 23 until the first gasket 262 contacts the first limiting ring 271, the second gasket 273 contacts the outer end of the corresponding heating outer cylinder 23, and the third gasket 274 contacts one end of the sealing cylinder 27, to seal between the air duct 26, the sealing cylinder 27, and the heating outer cylinder 23, without affecting the continued use of the electromagnetic heating element 24;

[0053] At the same time, the sealing cylinder 27 abuts against the corresponding driving abutting block 2311, and controls the positioning sliding frames 233 to move towards each other, always positioning the other end of the electromagnetic heating element 24.
