[0024] The utility model will be further explained in connection with the drawings and examples.
[0025] As Figures 1-3 shown, a kind of top hatch opening and closing mechanism suitable for island reef unmanned cabin body, the whole top hatch opening and closing mechanism adopts the installation form of sheet metal covering sealing and is buckled on island reef unmanned cabin body, including hatch skeleton 1, hatch skeleton 1 middle position is provided with hatch 2, two guide rails 3 are symmetrically set on the front and rear sides of the hatch skeleton 1, left hatch 4 and right hatch 5 are symmetrically set on the left and right sides of the hatch skeleton 1, left hatch 4 and right hatch 5 can be slidably set on guide rail 3 to cover or open hatch 2, rack 6 is fixedly set on the bottom of left hatch 4 and right hatch 5, two drive motors 7 are symmetrically set on the left and right sides of hatch skeleton 1, gear 8 is fixedly set on the output shaft of drive motor 7, and two gears 8 are engaged with corresponding two racks 6 respectively.
[0026] The driving motor 7 drives the gear 8 to rotate, and since the gear 8 engages with the rack 6, the rotation of the gear 8 drives the rack 6 to rotate, so that the left hatch 4 or the right hatch 5 slides left and right on the guide rail 3, thereby covering or opening the hatch 2. Through the two driving motors 7, single opening, single closing, double opening and double closing multiple switching states can be realized, thereby ensuring the flexibility of the hatch opening and closing.
[0027] The first limit switch 9 for detecting whether the left hatch 4 and the right hatch 5 are opened to the position is symmetrically arranged on the left and right sides of the hatch frame 1, and if opened to the position, the driving motor stops moving; the second limit switch for detecting whether the left hatch 4 and the right hatch 5 are closed to the position is symmetrically arranged at the middle position of the hatch frame 1, and if closed to the position, the driving motor stops moving.
[0028] As shown in Figure 4 , the guide rail 3 is in a C-shaped cross section, and a plurality of rubber rollers 10 are arranged at the front and rear ends of the left hatch 4 and the right hatch 5, and the left hatch 4 and the right hatch 5 are slidably arranged on the guide rail 3 through the rubber rollers 10. When the hatch moves, the rubber rollers 10 perform linear rolling in the C-shaped guide rail 3, and compared with the sliding movement of the same metal material without rollers, the rolling movement through the rubber material transition plays a certain damping effect.
[0029] As shown in Figure 5 , the left hatch 4 and the right hatch 5 are arranged with a height difference, the edge height of the left hatch 4 is 75 mm, and the edge height of the right hatch 5 is 70 mm, the edge of the left hatch 4 is higher than that of the right hatch 5, a groove is designed at the right end of the left hatch 4, and the right hatch 5 is fitted in the groove of the left hatch 4 by the height difference. The right end of the left hatch 4 is provided with a sealing bevel, and the left end of the right hatch 5 is provided with a 9-shaped door seal 11 made of silica gel. When the left hatch 4 and the right hatch 5 are closed, the sealing bevel of the left hatch 4 extrudes the 9-shaped door seal 11 of the right hatch 5, so that the 9-shaped door seal 11 is deformed to fill all the gaps at the joint, a sealing strip is formed along the closed part, and a sealing effect is achieved. Rain and salt can be effectively prevented from entering the island reef unmanned cabin through the gap between the two hatches and the hatch frame 1, and the adaptability and service life of the island reef unmanned cabin to the harsh environment of the island reef are improved.
[0030] As shown in Figure 2 and Figure 6 , the left end of the left hatch 4 and the right end of the right hatch 5 are fixedly provided with a dust removal plate 12, and a brush 15 is arranged on the dust removal plate 12, the brush 15 is transversely arranged between the two guide rails 3, and during the opening and closing process of the left hatch 4 or the right hatch 5 each time, the brush 15 will automatically clean the guide rail 3 once, thereby cleaning the dust, salt and other sundries deposited on the guide rail 3, keeping the guide rail 3 clean, and reducing the labor hours and costs of personnel maintenance and cleaning.
[0031] Two inner water baffle plates 13 for preventing rainwater from entering the hatch 2 are symmetrically arranged on the hatch door framework 1 at positions below the left hatch door 4 and the right hatch door 5, and outer water baffle plates 14 are arranged outside the inner water baffle plates 13. Two-layer waterproof effect is achieved through the inner water baffle plates 13 and the outer water baffle plates 14, and the stability of normal operation of the equipment inside the island reef unmanned cabin body is improved.
