Description

Technical Field

[0001] This utility model relates to the field of ship berthing equipment technology, and in particular to an emergency hatch. Background Technology

[0002] Existing emergency hatches mostly employ an embedded guard design, which requires the guard to be embedded into a pre-fabricated slot in the hull for positioning and locking. However, to meet the installation requirements of embedded guards, the hull structure must be pre-machined with slots that match the geometry of the guard; multiple levels of elastic sealing rings and pressure compensation systems must be installed to ensure the watertightness of the interface between the guard and the slot; and when the ship is tossed or impacted by waves, micro-displacement can easily occur between the embedded guard and the slot, leading to local compression failure of the sealing rings, significantly increasing manufacturing and maintenance costs.

[0026] Example 1:

[0027] like Figures 1 to 5As shown, an emergency hatch includes an emergency hatch frame 15, an emergency hatch body 13, and a motor 20. The motor 20 is located inside the emergency hatch frame 15 and drives a traction rope 21 to open and close the emergency hatch body 13. The emergency hatch frame 15 and the emergency hatch body 13 are connected by hinges. The emergency hatch body 13 can rotate up and down around the emergency hatch frame 15. The emergency hatch body 13 is provided with several protective devices, including a first fixed seat 1, a second fixed seat 2, and a baffle 3. The first fixed seat 1 is movably connected to the baffle 3 through a first folding member 4. The second fixed seat 2 is movably connected to the baffle 3 through a second folding member 5. The first folding member 4 is rotatably connected to the first fixed seat 1 through a rotating shaft. The first folding member 4 and the first fixed seat 1 are respectively provided with mutually cooperating locking structures. The locking structures lock the relative positions of the first folding member 4 and the first fixed seat 1, so that when the first folding member 4 and the second folding member 5 are unfolded outward, the baffle 3 will remain in the unfolded state. In use, the motor 20 drives the traction rope 21 to control the emergency hatch body 13 to rotate downwards. When the set angle is reached, the folded baffle 3 is folded outwards, which drives the first folding piece 4 and the second folding piece 5 to unfold outwards. When the second locking hole 44 on the first folding piece 4 coincides with the first locking hole 42 of the first fixed seat 1, it is locked by inserting a pin (or shaft).

[0028] In practical applications, the locking structure includes a first rotating hole 41, a first locking hole 42 and a locking member 61 provided on the first fixed base 1, and a corresponding second rotating hole 43 and a second locking hole 44 provided on the first folding member 4.

[0038] In practical applications, a locking element 61 is provided inside the placement hole.

[0039] The placement plate 6 is plate-shaped, and the locking element 61 is placed through the placement hole.

[0040] In practical applications, one end of the locking member 61 is connected to the placement plate 6 via a chain. The chain prevents the locking member 61 from disengaging and facilitates its access. When the second locking hole 44 on the first folding member 4 coincides with the first locking hole 42 of the first fixing base 1, the locking member 61 is inserted into the first locking hole 42 and the second locking hole 44 for locking.

[0041] In practical applications, the two ends of the first folding piece 4 are connected to the first fixed base 1 and the baffle 3 respectively via pins 7. The rotational connection is achieved through the pins 7, which is simple and convenient.

[0042] In practical applications, the two ends of the second folding member 5 are connected to the second fixed base 2 and the baffle 3 respectively via pins 7. The rotational connection is achieved through the pins 7, which is simple and convenient.

[0043] In practical applications, the side wall of the pin 7 is provided with a groove.

[0044] In practical applications, the groove abuts against the fixing plate 9.

[0050] In practical applications, the cross-section of baffle 3 is trapezoidal.

[0051] The effective effect of this utility model is that the baffle 3 is securely fixed by the locking member 61 when unfolded.

[0052] Example 2:

[0053] like Figures 1 to 5 As shown, an emergency hatch includes an emergency hatch frame 15, an emergency hatch body 13, and a motor 20.

The first fixed seat 1 is movably connected to the baffle 3 through a first folding member 4. The second fixed seat 2 is movably connected to the baffle 3 through a second folding member 5. The first folding member 4 is rotatably connected to the first fixed seat 1 through a rotating shaft. The first folding member 4 and the first fixed seat 1 are respectively provided with mutually cooperating locking structures. The locking structures lock the relative positions of the first folding member 4 and the first fixed seat 1, so that when the first folding member 4 and the second folding member 5 are unfolded outward, the baffle 3 will remain in the unfolded state. The inner side of the baffle 3 has a cavity, and the inner side of the baffle 3 has several spaced buffer blocks 14. In use, the motor 20 drives the traction rope 21 to control the emergency hatch body 13 to rotate downwards. When the set angle is reached, the baffle 3 in the folded state is folded outwards, which drives the first folding piece 4 and the second folding piece 5 to unfold outwards. When the second locking hole 44 on the first folding piece 4 coincides with the first locking hole 42 of the first fixing seat 1, a pin (or shaft) is inserted and locked. The hollow inner side of the baffle 3 can reduce weight, and the buffer block 14 further improves the buffering effect.

[0061] In practical applications, at least two protective devices are provided on any one side of the emergency hatch body 13. These devices provide rapid cushioning for approaching small vessels. A symmetrical arrangement is generally used for more even force distribution. The protective devices can also be installed on multiple sides of the emergency hatch body 13.
