[0004] The present invention adopts the following technical solution:

[0005] The present invention includes a frame base, an upper and lower groove rails horizontally fixedly installed on the inner walls of both sides of the frame base, a protective cover unit slidably installed on the upper groove rail, a push-pull linkage unit slidably installed on the lower groove rail, a drive unit installed at the end of the push-pull linkage unit, and a sealing assembly installed on the protective cover unit; a protective cover opening is provided on the top surface of the frame base; the top surface of the protective cover unit corresponds to the protective cover opening; the push-pull linkage unit is hinged to the bottom of the protective cover unit; vertical groove rails are provided at the right end and the left side of the right end of the upper groove rail; the right end of the lower groove rail is longer than the right end of the upper groove rail.

[0006] The push-pull linkage unit of the present invention includes two horizontally parallel transverse frame rods, diagonal bracing rods evenly hinged to each transverse frame rod, transverse frame rod guide wheels spaced apart on the outside of the transverse frame rods, and supports rotatably mounted on the outside of the ends of the diagonal bracing rods. The transverse frame rod guide wheels are rotatably mounted in the lower groove rail. The drive unit is installed at the left end of the two transverse frame rods. The support is fixedly connected to the bottom of the protective cover unit. The drive unit drives the protective cover unit and the push-pull linkage unit to run in the upper and lower groove rails respectively.

[0007] The drive unit of the present invention includes a connecting seat that is longitudinally fixedly installed at the left end of two transverse frame rods, a reducer that is fixedly installed on the lower left side of the connecting seat via a reducer seat, a motor installed at one end of the reducer, a right-angle commutator installed on the right side of the reducer, a drive shaft installed on the right-angle commutator via a bearing seat, gears installed at both ends of the drive shaft, and a rack that meshes with the gears on the base plate of the frame base.

[0008] The protective cover unit of the present invention includes an outer frame, an inner cover disposed on the top of the outer frame, outer frame guide wheels installed on the front and rear sides of the outer frame, and a proximity switch installed on the right end of the outer frame; the sealing assembly is disposed between the top of the outer frame and the frame base; two outer frame guide wheels are installed on each of the front and rear sides of the outer frame; two outer frame guide wheels are provided on each side of the outer frame, and when the protective cover reaches the highest position of the protective cover opening and contacts the top surface of the frame base to form a seal, the outer frame guide wheel on the right end slides into the vertical groove of the upper groove rail; the outer frame guide wheel on the left end slides into the vertical groove of the upper groove rail.

[0009] The inner wall of the protective cover opening of the present invention is a slope; the top surface of the outer frame is provided with a frame-shaped boss that is inserted into the protective cover opening, the outer wall of the frame-shaped boss is a slope that matches the inner wall of the protective cover opening, and the inner cover is sealed on the top surface of the frame-shaped boss; the sealing assembly includes an upper sealing strip disposed between the inner cover and the top surface of the frame-shaped boss and a lower sealing strip disposed between the bottom surface of the protective cover opening and the top surface of the outer frame.

[0010] The present invention has a handwheel installed at the other end of the reducer, and the handwheel is connected to the drive shaft through a right-angle reversing device.

[0011] The speed reducer described in this invention is a precision worm gear speed reducer with self-locking function; the motor is a six-phase winding servo motor.

[0012] The upper sealing strip of this invention uses a fluororubber gasket; the lower sealing strip uses a figure-9 shaped special-shaped sealing strip.

[0013] The positive effects of this invention are as follows: When the protective cover unit is fully open, the diagonal brace and the transverse sliding bracket of the push-pull linkage unit form a 45° angle. When the drive unit is working, it transmits power and displacement to the push-pull linkage unit. The diagonal brace and the transverse sliding bracket move laterally to the right at a 45° angle. When the guide wheel of the outer frame at the right end contacts the top of the vertical rail, the outer frame is blocked by the vertical rail and cannot continue to move laterally to the right. However, the guide wheel of the transverse sliding linkage is not limited, and the right end of the lower rail is longer than the right end of the upper rail. Therefore, the transverse sliding bracket continues to move laterally to the right, causing the angle between the diagonal brace and the transverse sliding bracket to increase. The outer frame is lifted upward as a whole. When the angle between the diagonal brace and the transverse sliding bracket reaches 90°, the outer frame reaches its highest position, and the inner cover contacts the top surface of the frame base and forms a seal. The overall operation process of the protective cover unit is: transverse movement, lifting and lowering, transverse movement. As the protective cover is about to close or open, the movement between the top surfaces of the outer frame base is vertical, ensuring that this movement does not generate shear force on the sealing strip, thus protecting the sealing effect. The outer wall of the frame-shaped boss is a bevel that matches the inner wall of the protective cover opening, forming a seal. Each transverse support rod is equipped with a transverse support rod guide wheel on its outer side. The transverse support rod guide wheels are steel wheels, and under extreme load conditions, all the load is ultimately borne by the four sets of steel wheels.

[0014] This invention adopts a flat-push structure, which is simple in structure and quick to open. Launch can be achieved in 3-4 seconds. The launch cover is flush with the deck, which expands the utilization range of the deck, facilitates the passage of inspection vehicles and maintenance personnel, and effectively utilizes the limited space of the deck.

[0027] The invention will now be described in further detail. In this description, the terms "left" and "right" are used to indicate position or direction. Figure 1 , 3 The direction is the standard.

[0028] As attached Figure 1-5 As shown, the present invention includes a frame base 1, an upper rail 2 and a lower rail 3 horizontally fixedly installed on the inner walls of both sides of the frame base 1, a protective cover unit slidably installed on the upper rail 2, a push-pull linkage unit slidably installed on the lower rail 3, a drive unit installed at the end of the push-pull linkage unit, and a sealing assembly installed on the protective cover unit; a protective cover opening 4 and a maintenance port 23 are provided on the top surface of the frame base 1; the top surface of the protective cover unit corresponds to the protective cover opening 4; the maintenance port 23 is located on one side of the protective cover opening 4, and a maintenance cover 24 is provided on the maintenance port 23; the push-pull linkage unit is hinged to the bottom of the protective cover unit; a vertical rail 201 is provided at the end of the upper rail 2; the right end of the lower rail 3 is longer than the right end of the upper rail 2. The upper surface of the frame base 1 is flush with the upper surface of the ship's deck, ensuring the surface flatness of the ship. The frame base 1 is used to support and position the upper and lower rails. While meeting structural strength requirements, the frame base 1 is designed with added weight-reducing holes, significantly reducing its overall weight. Simultaneously, to prevent water accumulation due to unforeseen circumstances, drainage outlets are designed on the end face of the frame base 1. When the protective cover unit is operating normally, the maintenance cover 24 is closed and maintains a certain flatness with the ship's deck. When maintenance is required, the maintenance cover 24 is opened, allowing for maintenance of the entire protective cover unit.

[0029] As attached Figure 6As shown, the push-pull linkage unit of the present invention includes two horizontally parallel and symmetrically arranged transverse frame rods 5, diagonal bracing rods 6 evenly hinged to each transverse frame rod 5, transverse frame rod guide wheels 7 spaced apart and installed on the outer side of the transverse frame rods 5, and supports 8 rotatably installed on the outer side of the ends of the diagonal bracing rods 6. The transverse frame rod guide wheels 7 are rotatably disposed in the lower groove rail 3. The drive unit is installed at the left end of the two transverse frame rods 5. The supports 8 are fixedly connected to the bottom of the protective cover unit. The drive unit drives the protective cover unit and the push-pull linkage unit to run in the upper groove rail 2 and the lower groove rail 3 respectively. In this embodiment, four transverse frame rod guide wheels 7 are installed on the outer side of each transverse frame rod 5. The transverse frame rod guide wheels 7 are steel wheels. Under extreme load conditions, all the load is ultimately borne by the four sets of steel wheels.

[0030] As attached Figure 7 , 8 As shown, the drive unit of this invention includes a connecting seat 9 longitudinally fixedly installed at the left end of the two transverse support rods 5, a reducer 10 fixedly installed on the lower left side of the connecting seat 9 via a reducer seat, a motor 11 installed at one end of the reducer 10, a right-angle commutator 12 installed on the right side of the reducer 10, a drive shaft 13 installed on the right-angle commutator 12 via a bearing seat, gears 14 installed at both ends of the drive shaft 13, and a rack 15 installed on the bottom plate of the frame base 1 that meshes with the gears 14. A handwheel 22 is installed at the other end of the reducer 10. The handwheel 22 cooperates with the drive shaft 13 through the right-angle commutator 12. In the event of an unexpected power failure of the motor 11, the handwheel 22 is used for driving. The motor 11 is a six-phase winding servo motor. If one set of windings fails and cannot work, the other set of windings can immediately intervene to drive the motor 11, ensuring its normal operation. The reducer 10 is a precision worm gear reducer with a self-locking function. The precision worm gear reducer can ensure the return clearance during the opening and closing of the protective cover, ensuring the sealing of the protective cover during opening and closing. The drive shaft 13 transmits the power output from the right-angle commutator 12 to the gear 14.

[0031] As attached Figure 9As shown, the protective cover unit of the present invention includes an outer frame 16, an inner cover 17 disposed on the top of the outer frame 16, outer frame guide wheels 18 installed on the front and rear sides of the outer frame 16, and a proximity switch 25 installed on the right end of the outer frame 16; the sealing assembly is disposed between the top of the outer frame 16 and the frame base 1; in this embodiment, two proximity switches 25 are provided, and the proximity switches 25 are selected from Kaget to ensure normal use in marine environments. To ensure accurate acquisition of the arrival signal, two proximity switches 25 are used for detection. Either proximity switch 25 can send a signal after detecting the arrival, which improves the accuracy of the arrival detection of the outer frame 16. Two outer frame guide wheels 18 are provided on the front and rear sides of the outer frame 16, respectively. The distance between the two outer frame guide wheels 18 is the distance between the two vertical groove rails 201. When the protective cover reaches the highest position of the protective cover opening 4 and contacts the top surface of the frame base 1 to form a seal, the outer frame guide wheel 18 on the right slides into the vertical groove rail 201 on the right side of the upper groove rail 2; the outer frame guide wheel 18 on the left slides into the vertical groove rail 201 on the left side of the upper groove rail 2.

[0032] As attached Figure 2 , 10 As shown in Figures 11 and 12, the top surface of the outer frame 16 is provided with a frame-shaped boss 19 that is inserted into the opening 4 of the protective cover. The outer side wall of the frame-shaped boss 19 is an inclined surface that matches the inner side wall of the opening 4 of the protective cover. The inner cover 17 is sealed on the top surface of the frame-shaped boss 19. The sealing assembly includes an upper sealing strip 20 disposed between the inner cover 17 and the top surface of the frame-shaped boss 19, and a lower sealing strip 21 disposed between the bottom surface of the opening 4 of the protective cover and the top surface of the outer frame 16. The upper sealing strip 20 is a sealing gasket made of fluororubber. The lower sealing strip 21 is a figure-9 shaped special sealing strip.

[0033] When the protective cover unit is fully open, the diagonal brace 6 and the transverse sliding brace 5 of the push-pull linkage unit form a 45° angle. When the drive unit is working, it transmits power and displacement to the push-pull linkage unit. The diagonal brace 6 and the transverse sliding brace 5 move laterally to the right at a 45° angle. When the guide wheel 18 of the outer frame at the right end contacts the top of the vertical rail 201, the outer frame 16 is blocked by the vertical rail 201 and cannot continue to move laterally to the right. The transverse sliding linkage's guide wheel... Since the guide wheel 7 was not limited, and the right end of the lower rail 3 was longer than the right end of the upper rail 2, the transverse support rod 5 continued to move to the right. This caused the angle between the diagonal support rod 6 and the transverse support rod 5 to increase, and the outer frame 16 was lifted upwards as a whole. When the angle between the diagonal support rod 6 and the transverse support rod 5 reached 90°, the outer frame 16 reached its highest position, and the inner cover 17 contacted the top surface of the frame base 1 and formed a seal, making the launch cover flush with the deck and expanding the usable area of ​​the deck. The overall operation process of the protective cover unit is: transverse movement, lifting and lowering, transverse movement. When the protective cover is about to close or open, the movement between the top surfaces of the outer frame 16 and the frame base 1 is in the vertical direction, ensuring that the instantaneous movement does not generate shear force on the sealing strip, thus protecting the sealing effect.

[0034] This invention adopts a flat-push structure, which is simple in structure and quick to open. Launch can be achieved in 3-4 seconds. The launch cover is flush with the deck, which expands the utilization range of the deck, facilitates the passage of inspection vehicles and maintenance personnel, and effectively utilizes the limited space of the deck.
