DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] A plurality of through holes 2 are provided at the bottom of the annular box 1, a blocking block 21 is provided inside the through hole 2, a gooseneck tube 22 is provided at the bottom of the annular box 1, and a nozzle 23 is provided at the bottom of the gooseneck tube 22;

[0040] In a low temperature environment, ice will quickly form between the moon pool cover and the deck of the ship, thereby restricting the moon pool cover to the deck. Therefore, the moon pool cover needs to be de-iced. The existing de-icing method is to heat the deck as a whole, heat the moon pool cover by heat conduction, and then melt the ice layer on the surface of the moon pool cover. This de-icing method consumes a lot of energy and has low efficiency. Therefore, the de-icing method of the moon pool cover needs to be further optimized. To solve the above problems, an annular box 1 is provided in an embodiment of the present invention. When in use, the annular box 1 is moved to the top of the moon pool structure, and the annular box 1 is supported by a pad 12 and a support frame 11. The inner circle area of ​​the annular box 1 is larger than the opening area of ​​the moon pool. Therefore, during the use of the moon pool, related equipment can pass through the annular box 1. When de-icing the cover surface, the top end of the gooseneck pipe 22 is first installed to a position connected to the through hole 2, and the corresponding blocking block 21 is The through hole 2 is drawn out to make the through hole 2 conductive; the shape of the gooseneck 22 is then adjusted. It should be noted that the gooseneck 22 is still stable after the shape adjustment; when the nozzle 23 at the bottom of the gooseneck 22 points to the ice layer between the moon pool cover and the deck, the pump body connected to the conduit 13 is started, and the pump body draws high-temperature liquid water into the annular box 1 through the conduit 13, and then sprays it through the gooseneck 22 and the nozzle 23 to the ice layer area between the cover and the deck, thereby de-icing the moon pool cover, and the de-icing position can be directional during de-icing, and the number and size of the gooseneck 22 can be adjusted as needed; this directional de-icing method does not require heating the deck as a whole, saves energy consumption and does not require heat conduction de-icing, so the de-icing efficiency is high; it should be noted that after the liquid water flows onto the deck, it will be guided to the designated position through a special water tank, and there will be no accumulation and icing.

[0041] like Figures 3 to 8As shown, a plurality of first magnetic plates 221 are evenly arranged on the side of the gooseneck tube 22, a pair of stabilizing rods 3 are arranged at the bottom end of the annular box 1 and on both sides of the gooseneck tube 22, a steering ball 32 is arranged at the bottom end of the stabilizing rod 3, a second magnetic plate 31 with a magnetism different from that of the first magnetic plate 221 is arranged on the side of the stabilizing rod 3, a connecting column 33 is arranged at one end of the stabilizing rod 3 close to the steering ball 32, a pair of arc-shaped grooves 34 are symmetrically opened at the upper and lower ends of the connecting column 33, the steering ball 32 is embedded in the arc-shaped groove 34 and has friction with the inner wall of the arc-shaped groove 34; a plurality of stabilizing rods 3 and a plurality of connecting columns 33 are sequentially connected through the cooperation of the steering ball 32 and the arc-shaped groove 34, and the specific number of installations is determined according to the needs. To be adjusted; after adjusting the shape of the gooseneck 22, the staff adjusts the connection angle between the stabilizer bar 3 and the connecting column 33, specifically controls the steering ball 32 to slide in the arc groove 34, and there is friction between the steering ball 32 and the arc groove 34, so the angle between the stabilizer bar 3 and the connecting column 33 remains stable after adjustment; before adjustment, the stabilizer bar 3 can be rotated to make the second magnetic plate 31 away from the first magnetic plate 221, so as to adjust the shape of the gooseneck 22; and after adjustment, the stabilizer bar 3 is rotated so that the first magnetic plate 221 is fixed by the second magnetic plate 31 through magnetic force, thereby restricting the deformed gooseneck 22, so that the gooseneck 22 remains stable, thereby improving the de-icing stability.

[0042] A pair of notches 4 are symmetrically provided on the side of the connecting column 33 based on the center, and the notches 4 are connected to the arc-shaped groove 34. A rectangular nut 41 is installed inside the notch 4, and a fastening bolt 42 is meshed and connected inside the rectangular nut 41. A twist handle is provided at one end of the fastening bolt 42 located outside the notch 4; a pressing block 43 is rotatably provided at one end of the fastening bolt 42 located inside the notch 4, and a side of the pressing block 43 facing the inside of the arc-shaped groove 34 is provided as an inner concave surface adapted to the surface of the steering ball 32; after adjusting the angle between the stabilizing bar 3 and the connecting column 33, the staff twists the twist handle at the end of the fastening bolt 42 to make the fastening bolt 42 mesh with the rectangular nut 41 for transmission, and the end of the fastening bolt 42 located in the notch 4 drives the inner concave surface of the pressing block 43 to face the surface of the steering ball 32 in the arc-shaped groove 34, and the friction between the pressing block 43 and the steering ball 32 further increases the connection stability between the stabilizing bar 3 and the connecting column 33, thereby further improving the stability of the gooseneck tube 22.

[0043] like Figures 9 to 14 As shown, a ball 121 is rotatably provided at the bottom end of the pad 12; when the annular box 1 moves, the ball 121 at the bottom end of the pad 12 rolls on the deck, making it convenient for the staff to adjust the position of the annular box 1.

[0044] An annular groove 122 is provided at the bottom end of the pad 12, and a first heating coil 123 is inserted into the annular groove 122. A pair of first conducting wires 124 are provided on the surface of the first heating coil 123, and the first conducting wires 124 are externally connected to a power source. When there is liquid water on the deck, the liquid water will contact the surface of the ball 121 and then freeze the ball 121. Therefore, a first heating coil 123 is provided in the annular groove 122, and the first heating coil 123 is energized with an external power source through the first conducting wire 124 to generate heat, thereby heating the pad 12 and the ball 121, and preventing the surface of the ball 121 from freezing and affecting the normal movement of the annular box 1.

[0045] A receiving plate 5 is provided on one side of the backing plate 12, and a mounting hole is provided on the top surface of the receiving plate 5; an air cylinder 51 is inserted through the mounting hole, a suction cup 52 is provided at the bottom end of the air cylinder 51, a first hose 53 is provided at the top end of the air cylinder 51, and an air pump is externally connected to the end of the first hose 53 away from the air cylinder 51;

[0046] There is friction between the air cylinder 51 and the inner wall of the mounting hole; after the position of the annular box 1 is determined, the air cylinder 51 is driven to move downward relative to the mounting hole, so that the suction cup 52 at the bottom of the air cylinder 51 contacts the deck surface, so that the opening of the suction cup 52 is blocked by the deck surface; then the air cylinder 51 is evacuated through the first hose 53 and the external air pump, so that the suction cup 52 is adsorbed onto the deck, thereby fixing the position of the annular box 1 to prevent the sliding between the ball 121 and the deck from causing the annular box 1 to move, thereby improving the stability of de-icing.

[0047] A second hose 54 is provided on the side of the air cylinder 51, and a valve 55 is provided on one end of the second hose 54 away from the air cylinder 51. The valve 55 is installed on the side of the annular box 1 and is connected to the inside of the annular box 1; when the suction cup 52 is not in contact with the deck, the valve 55 is opened, the valve 55 receives the liquid water in the annular box 1 and injects it into the air cylinder 51 through the second hose 54, and then sprays it out through the suction cup 52. The high-temperature liquid water will remove the ice layer on the deck under the suction cup 52. Then, when the suction cup 52 is in contact with the deck, the opening of the suction cup 52 is fully in contact with the deck, ensuring that the suction cup 52 is blocked by the deck to avoid interference from the ice layer on the deck surface.

[0048] An isolation ring 62 is provided on the outside of the air cylinder 51 and below the receiving plate 5, and a connecting plate 61 is provided on the top of the isolation ring 62. A guide rod 6 is vertically installed on the top of the connecting plate 61, and the top of the guide rod 6 passes through the top of the receiving plate 5; a second heating ring 63 is sleeved on the side of the isolation ring 62, and a pair of second wires 64 connected to an external power supply are provided on the surface of the second heating ring 63; when the suction cup 52 is adsorbed to the deck surface, the staff drives the isolation ring 62 to move downward through the connecting plate 61 and the guide rod 6, and stops when the bottom end of the isolation ring 62 contacts the deck surface, and then energizes the second heating ring 63 through the second wire 64 and the external power supply. After the second heating ring 63 is energized, it emits heat to heat the isolation ring 62, causing the isolation ring 62 to maintain a high temperature, and the suction cup 52 is surrounded by the isolation ring 62, so the suction cup 52 will not freeze between the deck, which is convenient for subsequent removal.

[0049] The isolation ring 62 is made of a high thermal conductivity material, so that the heat can be quickly transferred to the surrounding suction cup 52 , thereby ensuring the heating effect of the suction cup 52 .

[0050] like Figure 4 As shown, the nozzle 23 is specifically an atomizing spray head; liquid water sprayed through the atomizing spray head will increase the contact area between the liquid water and the ice layer, thereby increasing the de-icing area. The staff can adaptively use nozzles 23 with different atomization degrees according to needs to improve the flexibility of de-icing.

[0051] During operation, the annular box 1 is moved to the top of the moon pool structure, and the annular box 1 is supported by the pad 12 and the support frame 11. The inner circle area of ​​the annular box 1 is larger than the opening area of ​​the moon pool. Therefore, during the use of the moon pool, relevant equipment can pass through the annular box 1. When de-icing the surface of the cover plate, the top end of the gooseneck 22 is first installed to the position connected to the through hole 2, and the corresponding blocking block 21 is pulled out to make the through hole 2 conductive; then the shape of the gooseneck 22 is adjusted. It should be pointed out that the gooseneck 22 is still stable after the shape is adjusted; the nozzle 23 at the bottom end of the gooseneck 22 points to the moon pool. When there is ice between the cover plate and the deck, the pump body connected to the conduit 13 is started, and the pump body draws high-temperature liquid water into the annular box 1 through the conduit 13, and then sprays it to the ice layer area between the cover plate and the deck through the gooseneck 22 and the nozzle 23, thereby de-icing the moon pool cover plate, and the de-icing position can be directional during de-icing, and the number and size of the gooseneck 22 can be adjusted as needed; this directional de-icing method does not require heating the entire deck, saves energy consumption, and does not require heat conduction de-icing, so the de-icing rate is high; after adjusting the shape of the gooseneck 22, the staff can The connection angle between the stabilizer bar 3 and the connecting column 33 is adjusted, specifically, the steering ball 32 is controlled to slide in the arc groove 34. There is friction between the steering ball 32 and the arc groove 34, so the angle between the stabilizer bar 3 and the connecting column 33 remains stable after adjustment; before adjustment, the stabilizer bar 3 can be rotated to make the second magnetic plate 31 away from the first magnetic plate 221, so as to adjust the shape of the gooseneck tube 22; and after adjustment, the stabilizer bar 3 is rotated so that the first magnetic plate 221 is fixed by the second magnetic plate 31 through magnetic force, thereby restricting the deformed gooseneck tube 22, so that The gooseneck 22 remains stable, improving the de-icing stability; after adjusting the angle between the stabilizer bar 3 and the connecting column 33, the staff twists the twist handle at the end of the fastening bolt 42 to make the fastening bolt 42 engage with the rectangular nut 41, and the end of the fastening bolt 42 located in the notch 4 drives the inner concave surface of the pressing block 43 to face the surface of the steering ball 32 in the arc-shaped groove 34. The friction force between the pressing block 43 and the steering ball 32 further increases the connection stability between the stabilizer bar 3 and the connecting column 33, thereby further improving the stability of the gooseneck 22.

[0052] When the annular box 1 moves, the ball 121 at the bottom of the pad 12 rolls on the deck, which is convenient for the staff to adjust the position of the annular box 1; when there is liquid water on the deck, the liquid water will contact the surface of the ball 121, and then freeze the ball 121; therefore, a first heating coil 123 is arranged in the annular groove 122, and the first heating coil 123 is energized with an external power supply through a first wire 124 to generate heat, so as to heat the pad 12 and the ball 121, and prevent the surface of the ball 121 from freezing and affecting the normal movement of the annular box 1; after the position of the annular box 1 is determined, the driving gas The cylinder 51 moves downward relative to the mounting hole, so that the suction cup 52 at the bottom of the cylinder 51 contacts the deck surface, so that the opening of the suction cup 52 is blocked by the deck surface; then the cylinder 51 is evacuated through the first hose 53 and the air pump connected to it, so that the suction cup 52 is adsorbed on the deck, thereby fixing the position of the annular box 1 to prevent the sliding between the ball 121 and the deck from causing the annular box 1 to move, thereby improving the stability of deicing; wherein when the suction cup 52 is not in contact with the deck, the valve 55 is opened, the valve 55 receives the liquid water in the annular box 1 and injects it into the cylinder 51 through the second hose 54 , and then the high-temperature liquid water is sprayed out through the suction cup 52 to remove the ice layer on the deck below the suction cup 52. Then, when the suction cup 52 contacts the deck, the opening of the suction cup 52 fully contacts the deck to ensure that the suction cup 52 is blocked by the deck to avoid interference from the ice layer on the deck surface. When the suction cup 52 is adsorbed to the deck surface, the staff drives the isolation ring 62 downward through the connecting plate 61 and the guide rod 6, and stops when the bottom end of the isolation ring 62 contacts the deck surface. Then, the second heating ring 63 is energized through the second wire 64 and the external power supply. The second heating ring 63 is energized The heat is then emitted to heat the isolation ring 62, causing the isolation ring 62 to maintain a high temperature, and the suction cup 52 is surrounded by the isolation ring 62, so that the suction cup 52 will not freeze between the deck, and it is convenient to remove it later; wherein the isolation ring 62 is made of high thermal conductivity material; so that heat can be quickly transferred to the surrounding suction cup 52, ensuring the heating effect of the suction cup 52; wherein the liquid water is sprayed out through the atomizing spray head, which will increase the contact area between the liquid water and the ice layer, thereby increasing the deicing area, and the staff can adaptively use the spray heads 23 with different atomization degrees according to the needs to improve the flexibility of deicing.
