Description

Technical Field

[0001] This utility model relates to the field of ship hatch cover technology, and specifically discloses a ship hatch cover that is easy to open. Background Technology

[0002] As a key sealing component of a ship's cargo hold, the efficiency and reliability of the opening and closing of a ship's hatch cover directly affect the progress of cargo loading and unloading operations and the overall operational efficiency of the ship.

[0003] In existing technologies, some hatch covers employ mechanical drives, but their drive structure designs are not sufficiently optimized. For example, some drive mechanisms lack flexible switching methods; when the electric drive components malfunction, they cannot quickly switch to manual operation mode, leaving the hatch cover unable to open or close properly, causing significant inconvenience to ship operations. Simultaneously, the connection stability of some mechanical transmission structures is poor; during ship navigation, factors such as wave impacts can easily lead to loosening and jamming, affecting transmission efficiency and service life. Therefore, a more convenient hatch cover is needed to address these issues. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4 A ship hatch cover that is easy to open includes a hatch 1 and a hatch cover 4, and an actuation mechanism is provided between the hatch 1 and the hatch cover 4.

[0023] The starting mechanism includes two mounting plates 2 fixedly connected to the right end of the hatch 1. A rotating rod 6 is rotatably connected between the two mounting plates 2. A bracket 5 is fixedly connected to the outer wall of the rotating rod 6. The bracket 5 is fixedly connected to the hatch cover 4. L-shaped plates 3 are fixedly connected to both ends of the front mounting plate 2. A motor 11 is installed at the left end of the left L-shaped plate 3. The output end of the motor 11 passes through the L-shaped plate 3 and is fixedly connected to a first disc 13. A connecting shaft 15 passes through and is rotatably connected to the outer wall of the right L-shaped plate 3. A second disc 16 is fixedly connected to the left end of the connecting shaft 15. A worm gear 8 is provided between the first disc 13 and the second disc 16. The rotating rod 6 passes through the front mounting plate 2 and is fixedly connected to a worm wheel 7 that meshes with the worm gear 8. Two auxiliary discs 9 are fixedly connected to the outer wall of the worm gear 8. Threaded holes 17 are opened through the outer walls of both auxiliary discs 9. A threaded rod 10 is threadedly connected inside the threaded hole 17 at the left end. Two insertion holes 18 are opened through the outer walls of both the first disc 13 and the second disc 16.

[0024] In this embodiment: During electric drive, the output end of the motor 11 drives the first disk 13 to rotate. The rotation of the first disk 13 drives the worm gear 8 to rotate synchronously. The rotation of the worm gear 8 drives the worm wheel 7 to rotate, thereby causing the rotating rod 6 to rotate between the two mounting plates 2. The bracket 5 on the outer wall of the rotating rod 6 rotates with the rotating rod 6, and the bracket 5 is fixed to the hatch cover 4, thereby causing the hatch cover 4 to flip open. When closing the hatch cover 4, the control motor 11 reverses. Through the above-mentioned reverse transmission, the hatch cover 4 flips in the opposite direction to close with the hatch opening 1, and the sealing gasket 14 on the outer wall of the hatch cover 4 fits against the edge of the hatch opening 1 to achieve a seal.

[0025] When manual operation is required, first unscrew the threaded rod 10 in the threaded hole 17 of the left auxiliary disk 9 out of the insertion hole 18 of the first disk 13, and screw it into the threaded hole 17 of the right auxiliary disk 9, so that the threaded hole 17 is inserted into the interior of the second disk 16. Rotate the knob 12 on the outer wall of the right L-shaped plate 3. The knob 12 drives the connecting shaft 15 to rotate, and the second disk 16 at the left end of the connecting shaft 15 rotates accordingly, which in turn drives the worm gear 8 to rotate. The worm gear 8 drives the worm wheel 7 and the rotating rod 6 to rotate, which drives the hatch cover 4 to flip through the bracket 5, completing the opening or closing operation. By switching between electric and manual drive, combined with the transmission of the worm wheel 7 and the worm gear 8, the hatch cover 4 can be easily opened and closed to adapt to different working conditions.

[0026] As a technical optimization of this utility model, the left and right ends of the worm 8 are rotatably connected to the first disk 13 and the second disk 16 respectively through bearings.

[0027] In this embodiment, the bearing supports the worm 8, ensuring that the worm 8 always maintains the correct meshing position with the worm wheel 7, preventing the worm 8 from shifting due to factors such as turbulence and vibration during ship navigation, ensuring the stability and accuracy of the transmission structure, and extending the service life of the entire starting mechanism.

[0028] As a technical optimization of this utility model, a sealing gasket 14 is fixedly connected to the outer wall of the hatch 4.

[0029] In this embodiment: when the hatch cover 4 is closed and the hatch opening 1 is closed, the sealing gasket 14 can tightly fill the gap between the hatch cover 4 and the hatch opening 1, preventing seawater, rainwater, moisture and other substances from entering the cargo hold from the gap, avoiding damage to the cargo in the cargo hold due to moisture, and ensuring the quality and safety of the cargo.

[0030] As a technical optimization of this utility model, the outer wall of the motor 11 is fitted with a protective shell, and the protective shell is fixedly connected to the left L-shaped plate 3.

[0031] In this embodiment, the protective shell can prevent seawater, rainwater, etc. from entering the motor 11 and causing short circuit faults, prevent dust accumulation from affecting the normal heat dissipation and operation of the motor 11, and also reduce the damage to the motor 11 caused by cargo collisions.

[0032] As a technical optimization of this utility model, a knob 12 is installed on the outer wall of the L-shaped plate 3 at the right end, which is fixedly connected to the connecting shaft 15.

[0033] In this embodiment, the knob 12 facilitates manual operation of the connecting shaft 15. The knob 12 increases the contact area between the operator's hand and the connecting shaft 15, providing a convenient point of force for manual operation. By rotating the knob 12, the operator can more easily drive the connecting shaft 15 to rotate.

[0034] As a technical optimization of this utility model, a reinforcing rib is fixedly connected between the outer wall of the rotating rod 6 and the bracket 5.

[0035] In this embodiment, the reinforcing rib can effectively improve the structural strength of the connection between the rotating rod 6 and the bracket 5, avoid loosening or breakage due to long-term stress or excessive instantaneous impact, and ensure the stability of the connection between the two.

[0036] As a technical optimization of this utility model, the inner diameter of the insertion hole 18 is equal to the outer diameter of the threaded rod 10.

[0037] In this embodiment: when it is necessary to fix the relative position of the worm 8 and the first disk 13, the threaded rod 10 can be accurately inserted into the insertion hole 18. Since the two are of equal size, loosening or shaking can be avoided, ensuring the stability of the connection.

[0038] The working principle and usage process of this utility model are as follows: When electrically driven, the motor 11 is started, and the output end of the motor 11 drives the first disc 13 to rotate. Since the left and right ends of the worm gear 8 are rotatably connected to the first disc 13 and the second disc 16 respectively via bearings, the rotation of the first disc 13 will drive the worm gear 8 to rotate synchronously. The worm gear 8 meshes with the worm wheel 7 on the outer wall of the rotating rod 6. The rotation of the worm gear 8 drives the worm wheel 7 to rotate, thereby causing the rotating rod 6 to rotate between the two mounting plates 2. The bracket 5 on the outer wall of the rotating rod 6 rotates with the rotating rod 6, and the bracket 5 is fixed to the hatch cover 4, thereby causing the hatch cover 4 to flip open. When closing the hatch cover 4, the control motor 11 reverses direction. Through the above reverse transmission, the hatch cover 4 flips in the opposite direction to close with the hatch opening 1, and the sealing gasket 14 on the outer wall of the hatch cover 4 fits against the edge of the hatch opening 1 to achieve a seal.

[0039] When manual operation is required, first unscrew the threaded rod 10 in the threaded hole 17 of the left auxiliary disk 9 out of the insertion hole 18 of the first disk 13, and screw it into the threaded hole 17 of the right auxiliary disk 9, so that the threaded hole 17 is inserted into the interior of the second disk 16. Rotate the knob 12 on the outer wall of the right L-shaped plate 3. The knob 12 drives the connecting shaft 15 to rotate, and the second disk 16 at the left end of the connecting shaft 15 rotates accordingly, which in turn drives the worm gear 8 to rotate. The worm gear 8 drives the worm wheel 7 and the rotating rod 6 to rotate, which drives the hatch cover 4 to flip through the bracket 5, completing the opening or closing operation. By switching between electric and manual drive, combined with the transmission of the worm wheel 7 and the worm gear 8, the hatch cover 4 can be easily opened and closed to adapt to different working conditions.
