[0036] 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 first locking hole 42 on the first folding member 4 coincides with the second locking hole 44 of the first fixing base 1, the locking member 61 is inserted into the first locking hole 42 for locking.
[0037] 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.

[0040] In practical applications, the groove abuts against the fixing plate 9.
[0041] The cooperation between the fixing plate 9 and the groove makes the first folding piece 4 or the second folding piece 5 rotate stably.
[0042] In practical applications, a handle 10 is provided on the side wall of the baffle 3. The handle 10 facilitates the operation of the folding baffle 3.
[0043] In practical applications, the first fixing base 1 includes two spaced clamping plates 11, with a connecting block 8 between the two clamping plates 11. This makes the structure more stable.
[0044] In practical applications, a washer is provided between the clamping plate 11 and the first folding member 4. The washer reduces wear on the parts and improves their service life.
[0045] In practical applications, a washer is provided between the second folding component 5 and the second fixing seat 2. The washer reduces wear on the parts and improves their service life.

[0047] The effective effect of this utility model is that the baffle 3 is securely fixed by the locking member 61 when unfolded.
[0048] Example 2:
[0049] like Figures 1 to 5 As shown, a hatch has a hatch body 13 with several protective devices. The protective devices include a first fixed seat 1, a second fixed seat 2, and a baffle 3 connected to the first fixed seat 1 and the second fixed seat 2 respectively. A first folding member 4 is provided between the baffle 3 and the first fixed seat 1, and a second folding member 5 is provided between the baffle 3 and the second fixed seat 2. The two ends of the first folding member 4 are rotatably connected to the first fixed seat 1 and the baffle 3 respectively, and the two ends of the second folding member 5 are rotatably connected to the second fixed seat 2 and the baffle 3 respectively. The first fixed seat 1 has a first rotating hole 41, a first locking hole 42, and a locking member 61. The first folding member 4 has a corresponding second rotating hole 43 and a second locking hole 44. When the first folding member 4 and the second folding member 5 are unfolded outward, the locking member 61 locks the first locking hole 42 and the second locking hole 44, so that the baffle 3 remains 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 hydraulic cylinder 20 drives the hatch body 13 to rotate downward to a preset position, folding the baffle 3 outward, which in turn drives the first folding piece 4 and the second folding piece 5 to unfold outward. When the first locking hole 42 on the first folding piece 4 coincides with the second locking hole 44 of the first fixed seat 1, a pin (or shaft) is inserted and locked. The inner side of the baffle 3 is hollowed out, which can reduce the weight. The buffer block 14 further improves the buffering effect.
[0050] In practical applications, the side wall or top of the hatch frame 15 is equipped with a hydraulic locking device 16.

[0052] In practical applications, the door cover 17 is provided with a first sealing block 18, and the inner edge of the hatch frame 15 is provided with a second sealing block 19 that forms a seal with the first sealing block 18. The cooperation of the first sealing block 18 and the second sealing block 19 allows the hatch body 13 to rotate upward and close with the hatch frame 15 to form a seal.
[0053] In practical applications, at least two protective devices are provided on any one side of the hatch body 13. These protective devices quickly buffer small vessels that approach and dock. A symmetrical arrangement is generally used for more even force distribution. The protective devices can also be installed on multiple sides of the hatch body 13.

[0057] Locking component 61 is a locking pin.
[0058] The placement plate 6 is plate-shaped, and the locking element 61 is placed through the placement hole.
[0059] 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 locking hole 42 on the first folding member 4 coincides with the locking hole 42 on the first fixing base 1, the locking member 61 is inserted into the locking hole 42 for locking.
[0060] 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.
[0061] 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.
