[0002] Large hatches are quite tall, and in order to meet the ventilation requirements of some cargo, ventilation cover structures need to be designed on the side walls of the large hatches.

[0003] Existing ventilation cover structures are generally located high on the side wall of large hatches to enable the opening and closing of the ventilation cover. However, this requires the use of ladders or steps for the crew to reach the ventilation cover and manually operate it. This makes the existing ventilation cover structure extremely inconvenient to operate and unable to be opened and closed quickly, which is particularly disadvantageous in emergency situations.

[0029] Example 1:

[0030] like Figure 1 , 2 As shown in Figure 5, a ventilation device for a large hatch with a rapid opening and closing function includes a frame 1, which is disposed on the side wall of the large hatch. A cover plate 2 is provided on one side of the frame 1. The top of the cover plate 2 is hinged to the top of the frame 1 via a hinge 3. The frame 1 is provided with a limiting component for limiting the rotation angle of the cover plate 2. A slot 15 is provided at the bottom of the frame 1, and a limiting strip 16 is provided in the slot 15. A pin 10 is provided at the bottom end of the cover plate 2. The bottom end of the pin 10 can extend into the slot 15 and engage with the limiting strip 16. The pin 10 is driven to rise and fall by an opening and closing handle 19.

[0031] When opening, the operator stands on the deck or platform, holding the opening and closing handle 19. First, the fork 20 contacts the top rod, and the operator applies force to lift the pin 10 and initially lift the cover plate 2. Then, the operator hooks the auxiliary handle 9 with the hook 21 of the opening and closing handle 19 to further lift the cover plate 2 until the limit pin 6 slides to the top of the sliding groove 5 and enters the limit groove, thereby locking the cover plate 2 and preventing the cover plate 2 from covering the frame 1 again. When closing, the operator uses the fork 20 of the opening and closing handle 19 to support the support rod 7, so that the limit pin 6 disengages from the limit groove and enters the sliding groove 5. Then, the operator uses the fork 20 of the opening and closing handle 19 to move the support rod 7 upward, so that the cover plate 2 covers the frame 1. Then, the operator uses the hook 21 of the opening and closing handle 19 to insert the pin 10 downward into the slot 15, thereby achieving the engagement of the insert block 12 and the limit strip 16.

[0032] The auxiliary handle 9 is designed to facilitate the operator in lifting the cover plate 2 and increasing the opening speed of the cover plate 2. The guard rod 8 is designed to lock the opening and closing handle 19, facilitating the operator in lifting the latch 10 and initially lifting the cover plate 2.

[0033] The ventilation device of this utility model for a large hatch with a quick opening and closing function allows the operator to operate the latch 10 by operating the opening and closing handle 19 to open and close the cover 2. Moreover, by cooperating with the opening and closing handle 19 and the limiting component, the opening angle of the cover 2 can be adjusted and the cover 2 can be locked to prevent the cover 2 from being put back on the frame 1, making the operation convenient.

[0034] The limiting component includes two support plates 4, which are respectively hinged to both sides of the frame 1. A support rod 7 is provided between the two support plates 4. The two ends of the support rod 7 are respectively hinged to the ends of the two support plates 4 away from the frame 1. A sliding groove 5 is provided in the middle of the support plate 4. A limiting pin 6 is slidably engaged in the sliding groove 5. The limiting pin 6 is fixed to the side of the cover plate 2.

[0035] A limiting groove is provided above the top of the sliding groove 5, and the included angle between the limiting groove and the sliding groove 5 is 70-80 degrees.

[0036] The frame 1 is provided with a mesh 18 on the side facing the cover plate 2; the mesh 18 can filter out large particles of impurities and some dust from the outside to enter the cabin.

[0037] The frame 1 has a louver 17 in the middle; the louver 17 can adjust the ventilation volume.

[0038] The cover plate 2 is provided with a sealing ring on the side facing the frame 1, and the sealing ring is used to seal the gap between the cover plate 2 and the frame 1.

[0039] An auxiliary handle 9 is provided on one side of the bottom of the cover plate 2; the auxiliary handle 9 is provided to facilitate the operator to lift the cover plate 2 and increase the opening speed of the cover plate 2.

[0040] like Figure 3 As shown, a top rod is vertically provided at the top of the pin 10, and a plug block 12 is provided at the bottom of the pin 10. The plug block 12 is engaged with the limiting strip 16. The pin 10 is slidably engaged with the base plate 11. The base plate 11 is fixed to the cover plate 2. A top plate 14 is provided above the base plate 11. The pin 10 passes through the top plate 14. A limiting block 13 is provided below the top plate 14. The limiting block 13 is fixed to the middle of the pin 10.

[0041] The base plate 11 is provided with a guard rod 8 on the outside; the guard rod 8 is provided to lock the opening and closing handle 19, so that the operator can lift the pin 10 and initially lift the cover plate 2.

[0042] like Figure 4 As shown, the opening and closing handle 19 includes a grip portion, and forks 20 and hooks 21 are respectively provided on both sides of the grip portion.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
