DETAILED DESCRIPTION

[0035] The following will be combined Figure 1 The technical solution of the present invention is described in further detail.

[0036] Embodiment 1

[0037] The present invention provides a marine hatch cover, the structure of which is as follows: Figure 1-4 As shown. Figures 1 to 4 It can be seen that the marine hatch cover comprises a hatch 1 , a hatch cover 2 , a driving mechanism 3 and a locking mechanism 4 .

[0038] One side of the hatch 1 is connected to the hatch cover 2 matched with the hatch 1 through a rotating shaft and a shaft sleeve. The driving mechanism 3 is connected to the hatch 1 and the hatch cover 2 by driving the two ends of the telescopic rod 31 to rotate and open and close the hatch cover 2. The opening locking component 41 of the locking mechanism 4 is connected to the hatch cover 2 at one end and the hatch 1 at the other end, and is used to lock the position of the hatch cover 2 when the hatch cover 2 is in a fully open state. The closing locking component 42 of the locking mechanism 4 is located at the edge of the hatch cover 2, and is used to lock the position of the hatch cover 2 when the hatch cover 2 is in a fully closed state.

[0039] The detailed structure and function of each component are as follows:

[0040] In order to improve the tightness between the hatch 1 and the hatch cover 2, a pad 11 is provided on the bottom surface of the hatch 1. The pad 11 can be an independent pad or an annular pad extending along the hatch.

[0041] A pair of first ear plates and a pair of second ear plates are arranged on the inner side of the hatch 1 , wherein the first ear plates are connected to the driving mechanism 3 via a rotating shaft; and the second ear plates are connected to the opening locking assembly 41 of the locking mechanism 4 via a rotating shaft.

[0042] The driving mechanism 3 includes two symmetrically arranged driving telescopic rods 31, and the two ends of the driving telescopic rods 31 are respectively rotatably connected to the hatch 1 and the hatch cover 2, that is, one end of the movable rod of the driving telescopic rod 31 can rotate around the rotating shaft connected to the first ear plate on the inner side of the hatch 1, and the fixed tube end of the driving telescopic rod 31 is hinged to the hatch cover 2.

[0043] Since the two ends of the driving telescopic rod 31 are rotatably connected to the hatch 1 and the hatch cover 2 respectively, the hatch cover 2 can be opened quickly and completely through the driving telescopic rod 31, which is beneficial for the transportation of materials. The driving telescopic rod 31 can be a hydraulic cylinder, a pneumatic cylinder or other driving mechanism, or a screw mechanical structure driven by electricity.

[0044] The locking mechanism 4 comprises an opening locking assembly 41 for locking the position of the hatch cover 2 when the hatch cover 2 is in a fully open state, and a closing locking assembly 42 for locking the position of the hatch cover 2 when the hatch cover 2 is in a fully closed state.

[0045] There are one or two opening and locking components 41, which are centrally or symmetrically arranged between the two driving telescopic rods 31. The opening and locking component 41 includes a guide rod 411, a bracket 412, an opening and locking drive, and a first locking pin 413 connected to the opening and locking drive. The bracket 412 is fixedly arranged on the back of the hatch 2, and a guide shaft is arranged on the bracket 412; one end of the guide rod 411 is rotatably connected to the second ear shaft of the hatch 1 through a rotating shaft, and a guide long groove 411-1 is arranged on the guide rod 411, and the guide shaft is inserted into the guide long groove 411-1; the other end of the guide rod 411 is provided with a pin hole that can cooperate with the first locking pin 413. When the hatch 2 is fully opened, the pin hole on the guide rod 411 corresponds to the first locking pin 413.

[0046] As the hatch cover 2 is opened, the guide shaft on the bracket 412 moves in the guide slot 411-1; when the hatch cover 2 is fully opened, the opening and locking drive drives the first positioning pin 413 to be inserted into the pin hole on the guide rod 411, so that the hatch cover 2 can be locked in the fully opened state, thereby ensuring the safety of people entering and exiting the cabin. The above-mentioned opening and locking drive can be a hydraulic cylinder, a pneumatic cylinder or other driving mechanism, or a screw mechanical structure driven by electricity.

[0047] The closing locking assembly 42 is one or more (such as five closing locking assemblies 42), which are arranged on the edge of the hatch cover 2; the closing locking assembly 42 includes a closing locking drive and a second locking pin 421 connected to the closing locking drive, and cooperates with the bottom pad 11 of the hatch 1. When the hatch cover 2 is closed, the closing locking drive drives the second locking pin 421 to be inserted under the pad 11 of the hatch 1, so that the hatch cover 2 can be firmly fixed to the hatch 1, which can not only improve the safety in the cabin, but also has good explosion-proof performance. The above-mentioned closing locking drive can be a hydraulic cylinder, a driving mechanism such as a pneumatic cylinder, or a screw mechanical structure driven by electricity.

[0048] In order to improve the sealing performance of the marine hatch cover, a rubber gasket 21 is provided around the edge of the back side of the hatch cover 2 .

[0049] In order to further improve the explosion and fire resistance of the hatch cover, a fire rope 5 is arranged around the edge of the hatch 1.

[0050] In order to achieve excellent waterproof sealing, a waterproof convex strip 12 is provided on the inner side of the fire rope 5 at the edge of the hatch 1 .

[0051] In order to improve the degree of automation of the hatch cover, a proximity switch 6 is provided at the edge of the back side of the hatch cover 2; a sensing part corresponding to the proximity switch 6 is provided on the hatch 1, thereby realizing automatic control of the closing and locking assembly.

[0052] In the above-mentioned embodiment 1, two symmetrically arranged driving telescopic rods 31 are provided in the driving mechanism 3 as an example for explanation, but the present invention is not limited thereto, and three driving telescopic rods 31 may also be provided. The locking mechanism 4 includes two opening locking components 41 and five closing locking components 42, but the present invention is not limited thereto, and one opening locking component 41 and several closing locking components 42 may also be provided.

[0053] The working principle of the present invention is as follows:

[0054] The present invention rotatably connects the two ends of the driving telescopic rod 31 to the hatch 1 and the hatch cover 2 respectively. By driving the telescopic rod 31 to extend and retract, the hatch cover 2 can be quickly opened and closed, and the hatch cover can be fully opened, which is beneficial to the transportation of materials.

[0055] As the hatch cover 2 opens, the guide shaft on the bracket 412 will move in the guide slot 411-1; when the hatch cover 2 is fully opened, the opening locking drive drives the first positioning pin 413 to insert into the pin hole on the guide rod 411, so that the hatch cover 2 can be locked in the fully open state, thereby ensuring the safety of people entering and exiting the cabin.

[0056] When the hatch cover 2 is closed, the closing locking drive drives the second locking pin 421 to be inserted under the pad 11 of the hatch 1, so that the hatch cover 2 can be firmly fixed to the hatch 1, which can not only improve the safety in the cabin, but also have good explosion-proof performance. A proximity switch 6 is also provided at the edge of the back of the hatch cover 2; a sensing part corresponding to the proximity switch 6 is provided on the hatch 1, which can automatically control the range of movement of the closing locking component, thereby realizing automatic control of the closing locking component. The proximity switch is a magnetic switch, an inductive or capacitive switch. When the sensing part of the magnetic material or ferrite material is close to the sensing surface of the proximity switch 6, the internal electrical components of the proximity switch are turned on and off, thereby outputting a control signal.

[0057] Although the present invention has been disclosed as above with preferred embodiments, the embodiments do not limit the present invention. Any equivalent changes or modifications made without departing from the spirit and scope of the present invention also belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the content defined by the claims of this application.
