Traditional ship hatch covers mostly adopt multi-point mechanical locking. Although these designs can meet the basic functional requirements, there are many deficiencies in actual operation. For example, when opening, it is necessary to unlock manually at multiple points in sequence before the hatch cover can be opened. Moreover, in the sea environment, due to corrosion, the locking device of the hatch cover will rust, resulting in a significant increase in the difficulty of opening the hatch cover. It is very difficult to quickly open the hatch cover in an emergency. Content of the Utility Model

[0024] Refer to Figures 1-6 As shown, it includes a hatch cover 2 installed on the hatch 1 through a rotating base 3. The hatch cover 2 is provided with a solar power generation component 6 and a battery protection case 4. A battery is provided in the battery protection case 4, and the solar power generation component 6 is electrically connected to the battery; a vacuum locking structure and a pneumatic unlocking structure are provided in the hatch cover 2. An induction switch 20 is provided on the inner side of the hatch cover 2, and a handle 7 is provided on the hatch cover 2. An opening button 8 connected to the pneumatic unlocking structure is provided in the handle 7.

[0025] Refer to Figures 1-7 As shown, the vacuum locking structure includes an air cavity 16 opened in the hatch cover 2. A plurality of adsorption connection grooves 14 are opened on the periphery of the back side of the hatch cover 2. A plurality of connection holes 15 are opened in the hatch cover 2. The two ends of the connection hole 15 are respectively connected to the adsorption connection groove 14 and the air cavity 16. A plurality of sealing rings 10 matching the adsorption connection grooves 14 are provided on the hatch 1. The sealing rings 10 are all installed on the hatch 1 through the mounting seats 9. The sealing rings 10, the mounting seats 9 and the hatch 1 are all sealed and installed. The outer side of the sealing ring 10 is fitted in the adsorption connection groove 14; a micro vacuum pump 12 is provided in the vacuum drive box 5. The induction switch 20 is electrically connected to the micro vacuum pump 12. An air extraction hole 17 is opened in the hatch cover 2. The two ends of the air extraction hole 17 are respectively connected to the micro vacuum pump 12 and the air cavity 16; a plurality of ventilation and filtration holes 11 are opened on both sides of the vacuum drive box 5.

[0026] As an optimized solution of the present invention, the micro vacuum pump 12 is set to pump air outwards, so as to pump air outwards through the air extraction hole 17, and reduce the air pressure between the adsorption connection groove 14 and the sealing ring 10 through the air cavity 16 and the connection hole 15, so that the hatch cover 2 and the hatch 1 are adsorbed, and the hatch cover 2 is fixed. The outside air can flow into the vacuum drive box 5 from the ventilation and filtration holes 11, and filter the dust mixed in the air.

[0027] Refer to Figures 1-7 As shown, a one-way valve 18 is connected in the air extraction hole 17, and the conduction direction of the one-way valve 18 is set towards the micro vacuum pump 12.

[0028] As an optimized solution of the present invention, the one-way valve 18 is set to maintain the air flow direction and assist the micro vacuum pump 12 to maintain stability.

[0029] Refer to Figures 1-7As shown in the figure, the air pressure unlocking structure includes an electromagnetic air valve 13 disposed in the vacuum drive box 5. The opening button 8 is electrically connected to the electromagnetic air valve 13. One end of the electromagnetic air valve 13 is connected to the air extraction hole 17 through a pressurized connection hole 19 formed in the hatch cover 2, and the connection between the pressurized connection hole 19 and the air extraction hole 17 is located between the one-way valve 18 and the air chamber 16.

[0030] As an optimized solution of the present invention, the electromagnetic air valve 13 is controlled by the opening button 8. When the electromagnetic air valve 13 is turned on, external air can be sucked into the air chamber 16 from the open port of the electromagnetic air valve 13, so that the air pressure in the adsorption connection groove 14 and the sealing ring 10 is the same as that of the outside world. Then the user can open the hatch cover 2.

[0031] The usage process of the present invention:

[0032] When it is necessary to close the hatch cover 2, push the hatch cover 2 inward to close the door. While closing the door, the sealing ring 10 enters the adsorption connection groove 14 and is pressed tightly. The induction switch 20 in the hatch cover 2 senses the hatch opening 1 and then controls the micro vacuum pump 12 to start. The micro vacuum pump 12 extracts the gas in the air chamber 16, and the air pressure in the adsorption connection groove 14 decreases. The low pressure makes the hatch cover 2 and the hatch opening 1 adsorbed and fixed to complete the door closing.

[0033] When it is necessary to open the hatch cover 2, hold the handle 7 and press the opening button 8. The opening button 8 controls the electromagnetic air valve 13 to conduct, and external air flows into the air chamber 16. The air pressure inside and outside the hatch cover 2 is balanced, and the hatch cover 2 can be opened.

[0034] The photovoltaic power generation component 6 can generate electric energy when exposed to light and store it in the battery, so as to supply the devices inside the hatch cover 2 for use without external power supply.

[0035] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention.
