Description

A marine lighting fixture Technical Field

[0001] The present invention belongs to the technical field of lighting fixtures, and in particular relates to a marine lighting fixture. Background Art

[0002] Marine lighting fixtures are commonly used lighting equipment during navigation. Ship lighting fixtures have special designs and functions to adapt to the marine environment and navigation needs. Common types of marine lighting fixtures include navigation lights, anchor lights, signal lights, sidelights and warning lights. Marine lighting fixtures usually need to comply with the regulations and standards of the International Maritime Organization to ensure the safety and visibility of ships when sailing at sea. Existing lighting fixtures are generally equipped with angle adjustment functions, which are suitable for multi-directional and multi-angle adjustment operations. However, the angle adjustment drive method currently used in lighting fixtures is directly driven by a motor, and the lamp is directly driven by the motor's drive shaft to rotate and adjust. When strong winds occur, the lamp will be subject to greater external resistance. At this time, the motor's drive shaft will directly bear the external resistance, which will cause damage to the connection between the motor and the drive shaft for a long time, thereby affecting the subsequent angle adjustment of the lighting fixture, and further increasing the overall loss of the lighting fixture. Therefore, a marine lighting fixture is proposed.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention is provided with a hydraulic cylinder, a second piston and a second spring. Due to the operation of the driving motor, the rotating shaft can drive the gear and the extrusion plate to rotate. At this time, the gear and the rack are engaged, and the limit block is driven to move to the left through the rack. At the same time, the fixed plate is driven to move to the left along the outer surface of the limit rod, which can make the fixed plate drive the moving rod to move to the left. Due to the movement of the moving rod, the moving block can move to the left and squeeze the second spring. Due to the elastic recovery effect of the second spring, the second spring can slowly push the second piston and make the second piston move to the left. The oil inside the hydraulic cylinder is squeezed and pushed into the connecting pipe by the second piston. The inside of the connecting frame is pressed and the one-way valve is squeezed open at the same time, the oil is transported to the inside of the liquid cylinder, and the piston one, connecting rod and movable block two are squeezed to move upward. At the same time, the spring one is compressed. Due to the movement of the movable block two, the connecting plate, the lamp body and the movable shaft can be pushed to rotate along the inside of the connecting frame, and the lighting angle of the lamp body can be adjusted. This design can avoid the drive motor directly driving the lamp body to rotate and adjust through the rotating shaft. When strong winds occur, the drive motor and the rotating shaft will not directly bear external resistance, thereby avoiding damage caused by long-term connection between the drive motor and the rotating shaft, and ensuring that the lamp body can be adjusted normally in the future.

[0023] 2. The present invention provides a baffle, a push rod and a piston three. Due to the rotation of the extrusion disk, the extrusion disk can squeeze the rotating shaft, the air cylinder and the moving seat to the left, and the moving seat can move along the outer surface of the round rod. At this time, the push rod and the piston three will retract toward the inside of the air cylinder, and at the same time compress the spring four and the spring three. At this time, the baffle can be kept to close the inside of the connecting box. When the lamp body needs to be adjusted in the other direction, the operation of the driving motor can make the rotating shaft drive the gear and the extrusion disk to rotate in the other direction. Due to the rotation of the gear, the rack, the limit block, the fixed plate, the moving rod and the moving block can be driven to the right, and the spring two and the piston two can be pulled to the right at the same time. Since the extrusion disk rotates in the other direction, the elastic force of the spring three can restore the moving seat to drive the air cylinder and the push block to The piston moves to the right, and due to the elastic recovery effect of spring four, the slider, push rod and piston three will move to the left. Since the flow of the single air hole is less than the flow of the air hole group, resistance will be generated on the movement of piston three, which will slowly push the slider and baffle to the left. Since there is no resistance to the movement of the moving seat, the air cylinder will drive the baffle to the right and release the sealing effect inside the connecting box. Due to the elastic recovery effect of spring one, piston one, connecting rod and movable block two can be pushed downward, and the lamp body can be rotated in the other direction. Due to the movement of piston one, the oil can be squeezed through the connecting pipe into the inside of the elbow, and through the elbow into the inside of the connecting box, and then returned to the inside of the liquid cylinder through the connecting box, thereby ensuring the stability of the lamp body adjustment to the other side.

[0024] 3. The present invention sets a movable disk, a clamping hole and a clamping rod. When the driving motor needs to run, the controller will energize the electromagnet assembly. At this time, the electromagnet assembly will generate suction on the magnet block, thereby driving the movable plate and the clamping rod to move outward along the outer surface of the fixed rod, and causing the clamping rod to detach from the inside of the clamping hole. At the same time, the spring five is compressed, thereby releasing the fixing effect of the movable disk, movable shaft and lamp body. When the driving motor stops running and the lamp body stops rotating, the controller will cut off the power to the electromagnet assembly. At this time, the electromagnet assembly will lose the suction of the magnet block. Due to the elastic recovery effect of the spring five, the movable plate and the clamping rod can be pushed to move inward along the outer surface of the fixed rod, and finally be clamped in the inside of the corresponding clamping hole, so that the movable disk, movable shaft and lamp body can be locked and fixed, thereby strengthening the fixation of the lamp body after angle adjustment, thereby improving the overall wind resistance of the marine lighting fixture.

[0044] Among them, the lamp assembly includes a support plate 2, which is fixedly mounted on the top of the mounting base 1, and both sides of the top of the support plate 2 are fixedly connected to a connecting frame 3, the internal movable sleeve of the connecting frame 3 is connected with a movable shaft 5, one end of the movable shaft 5 is fixedly connected to the lamp body 4 located inside the connecting frame 3, and the rear of the lamp body 4 is fixedly connected to a connecting plate 6, the top of the support plate 2 is hinged with a movable block 7, the top of the movable block 7 is fixedly connected to a liquid cylinder 8, the interior of the liquid cylinder 8 is provided with a piston 11 that can move up and down, the top of the piston 11 is fixedly connected to a connecting rod 9, the other end of the connecting rod 9 passes through the liquid cylinder 8 and extends to the top of the liquid cylinder 8 and is fixedly connected with a movable block 2 10, the movable block 2 10 is hinged to the connecting plate 6, the outer surface of the connecting rod 9 is provided with a spring 13, one end of the spring 13 is connected to the piston 11, and the other end of the spring 13 is fixedly connected to the inner wall of the liquid cylinder 8.

[0045] Among them, the buffer assembly includes a liquid cylinder 14, the liquid cylinder 14 is fixedly mounted on the inside of the mounting base 1, one end of the liquid cylinder 14 is fixedly connected to a connecting pipe 15, the other end of the connecting pipe 15 extends to the outside of the mounting base 1 and is fixedly communicated with the fluid cylinder 8, the internal fixed sleeve of the connecting pipe 15 is provided with a one-way valve 16, the internal sleeve of the liquid cylinder 14 is provided with a piston 2 17 that can move left and right, the left side of the piston 2 17 is fixedly connected to a spring 2 18, the other end of the spring 2 18 is fixedly connected to a moving block 19 that can move left and right inside the liquid cylinder 14, the left side of the moving block 19 is fixedly connected to a moving rod 20, and the other end of the moving rod 20 extends to the outside of the liquid cylinder 14.

[0046] When in use, when the moving rod 20 moves to the left, the moving block 19 can be moved to the left and squeeze the spring 2 18. Due to the elastic recovery effect of the spring 2 18, the spring 2 18 can slowly push the piston 2 17 and make the piston 2 17 move to the left. The oil inside the cylinder 14 is squeezed and pushed into the interior of the connecting pipe 15 by the piston 2 17, and the one-way valve 16 is squeezed open to transport the oil to the interior of the cylinder 8, and the piston 11, the connecting rod 9 and the movable block 2 10 are squeezed upward. At the same time, the spring 13 When compressed, the movement of the movable block 210 can push the connecting plate 6, the lamp body 4 and the movable shaft 5 to rotate along the inside of the connecting frame 3, and realize the adjustment of the lighting angle of the lamp body 4. This design can avoid the driving motor 26 directly driving the lamp body 4 to rotate and adjust through the rotating shaft 27. When strong winds occur, the driving motor 26 and the rotating shaft 27 will not directly bear external resistance, thereby avoiding damage caused by long-term connection between the driving motor 26 and the rotating shaft 27, and ensuring that the lamp body 4 can be normally adjusted in angle later.

[0047] As shown in the figure, in one embodiment, the driving assembly includes a limiting rod 21, and two limiting rods 21 are provided. The two limiting rods 21 are fixedly connected to the front and rear of the mounting seat 1 respectively. The outer surface of the limiting rod 21 is movably sleeved with a limiting block 23. The left side of the limiting block 23 is fixedly connected to a fixed plate 22 sleeved on the outer surface of the limiting rod 21, and the fixed plate 22 is fixedly connected to the moving rod 20.

[0048] The working principle and beneficial effects of the above technical solution are as follows: a limit block 23 is set, and when the limit block 23 drives the fixed plate 22 to move to the left along the outer surface of the limit rod 21, the fixed plate 22 can drive the moving rod 20 to move to the left, thereby pushing the moving rod 20.

[0049] As shown in the figure, in one embodiment, the drive assembly also includes a support base 25, which is fixedly installed inside the mounting base 1 and is located in front of the limit block 23. A drive motor 26 is fixedly installed on the top of the support base 25, and the drive motor 26 is driven by a rotating shaft 27. The outer surface of the rotating shaft 27 is fixedly sleeved with a gear 28, and the outer surface of the bottom of the gear 28 is meshed with a rack 24, which is fixedly connected to the limit block 23. The outer surface of the rotating shaft 27 is fixedly sleeved with an extrusion disk 12 located behind the gear 28.

[0050] The working principle and beneficial effects of the above technical solution are as follows: a drive motor 26 is provided. Due to the operation of the drive motor 26, the rotating shaft 27 can drive the gear 28 and the extrusion disk 12 to rotate. At this time, the gear 28 and the rack 24 are engaged, and the limit block 23 is driven to move to the left through the rack 24, thereby driving the limit block 23.

[0051] As shown in the figure, in one embodiment, the reflux assembly includes a bend pipe 29, one end of which is fixedly connected to the connecting pipe 15 and is located above the one-way valve 16, and the other end of the bend pipe 29 extends to the interior of the mounting base 1 and is fixedly connected to a connecting box 30, which is fixedly connected to the liquid cylinder 14.

[0052] The working principle and beneficial effect of the above-mentioned technique scheme are: bend pipe 29 is set, due to the design of bend pipe 29, the oil in fluid cylinder 8 inside can be made to enter into the inside of bend pipe 29 by connecting pipe 15, and enter into the inside of communication box 30 by bend pipe 29, and then flow back to the inside of fluid cylinder 14 by communication box 30, due to the design of bend pipe 29, the reflux of oil can be facilitated.

[0053] As shown in the figure, in one embodiment, the reflux assembly also includes a round rod 31, which is fixedly connected to the left side of the inside of the mounting seat 1 and is located on the outside of the connecting box 30. The other end of the round rod 31 is fixedly connected to a mounting plate 38, and the mounting plate 38 is fixedly connected to the mounting seat 1. The outer surface of the mounting plate 38 is movably sleeved with a slider 32, and one side of the slider 32 is fixedly connected to a baffle 33 that can be snapped into the inside of the connecting box 30.

[0054] The working principle and beneficial effects of the above technical solution are as follows: a slider 32 is set, and when the slider 32 drives the baffle 33 to move to the left along the outer surface of the round rod 31, the slider 32 can drive the baffle 33 to detach from the inside of the connecting box 30, thereby releasing the sealing effect of the connecting box 30.

[0055] As shown in the figure, in one embodiment, the outer surface of the round rod 31 is movably sleeved with a movable seat 39 located on the right side of the slider 32, and the interior of the movable seat 39 is fixedly installed with an air cylinder 36. The outer side of the movable seat 39 is fixedly connected to a spring three 40, and the other end of the spring three 40 is fixedly connected to the mounting seat 1. The interior of the air cylinder 36 is sleeved with a piston three 35 that can move left and right, and the left side of the piston three 35 is fixedly connected to a push rod 34. The left end of the push rod 34 extends to the outside of the air cylinder 36 and is fixedly connected to the slider 32. The outer surface of the push rod 34 is sleeved with a spring four 41, one end of the spring four 41 is fixedly connected to the air cylinder 36, and the other end of the spring four 41 is fixedly connected to the slider 32. The right side of the air cylinder 36 is fixedly connected to a push block 37.

[0056] The working principle and beneficial effects of the above technical solution are as follows: a push block 37 and an air cylinder 36 are provided. Due to the rotation of the extrusion disk 12, the extrusion disk 12 can squeeze the rotating shaft 27, the air cylinder 36 and the movable seat 39 to the left, and the movable seat 39 can move along the outer surface of the round rod 31. At this time, the push rod 34 and the piston three 35 will shrink toward the inside of the air cylinder 36, and at the same time compress the spring four 41 and the spring three 40. At this time, the baffle 33 can be kept to close the interior of the connecting box 30.

[0057] As shown in the figure, in one embodiment, a single air hole 42 is opened on the left side of the top of the air cylinder 36, and an air hole group 43 is opened around the right side of the outer surface of the air cylinder 36.

[0058] The working principle and beneficial effects of the above technical solution are as follows: a single air hole 42 and an air hole group 43 are set. When the extrusion disk 12 rotates in the other direction, due to the elastic recovery effect of the spring three 40, the movable seat 39 can drive the air cylinder 36 and the push block 37 to move to the right. At the same time, due to the elastic recovery effect of the spring four 41, the slider 32, the push rod 34 and the piston three 35 will move to the left. Since the flow rate of the single air hole 42 is less than the flow rate of the air hole group 43, resistance will be generated on the movement of the piston three 35, thereby slowly pushing the slider 32 and the baffle 33 to move to the left. Since there is no resistance to the movement of the movable seat 39, the air cylinder 36 will drive the baffle 33 to move to the right, and the sealing effect inside the connecting box 30 will be released.

[0059] As shown in the figure, in one embodiment, the fixing assembly includes a movable disk 44 and a connecting seat 46. The movable disk 44 is fixedly sleeved on the outer surface of the movable shaft 5 and is located on the outside of the connecting frame 3. A clamping hole 45 is opened around the inside of the movable disk 44. The connecting seat 46 is fixedly connected to the outside of the connecting frame 3. The top of the connecting seat 46 is fixedly installed with a protective shell 48 located on the outside of the movable disk 44. The top of the connecting seat 46 is fixedly installed with a fixed seat 47 located on the outside of the protective shell 48. The inside of the fixed seat 47 is fixedly connected to a fixing rod 50. The outer surface of the fixed rod 50 is movably sleeved with a movable plate 51. The inner side of the movable plate 51 is fixedly connected with a clamping rod 52. The other end of the clamping rod 52 passes through the inner wall of the fixed seat 47 and the protective shell 48 and is clamped in the inside of the clamping hole 45.

[0060] The working principle and beneficial effects of the above technical solution are as follows: a clamping rod 52 is set, and when the movable plate 51 and the clamping rod 52 move outward along the outer surface of the fixed rod 50, the clamping rod 52 can be disengaged from the inside of the clamping hole 45, and at the same time the spring 53 is compressed, thereby releasing the fixing effect of the movable disk 44, the movable shaft 5 and the lamp body 4, and the lamp body 4 will now obtain movable performance.

[0061] As shown in the figure, in one embodiment, a magnet block 54 is fixedly connected to the outer side of the movable plate 51, an electromagnet assembly 49 is provided on the outer side of the interior of the fixed seat 47, and a spring 53 is sleeved on the outer surface of the fixed rod 50. One end of the spring 53 is connected to the movable plate 51, and the other end of the spring 53 is connected to the fixed seat 47.

[0062] The working principle and beneficial effects of the above technical solution are as follows: an electromagnet assembly 49 is provided. When the drive motor 26 needs to be operated, the controller will energize the electromagnet assembly 49. At this time, the electromagnet assembly 49 will generate suction force on the magnet block 54, thereby driving the movable plate 51 and the clamping rod 52 to move outward along the outer surface of the fixed rod 50, and causing the clamping rod 52 to disengage from the inside of the clamping hole 45. At the same time, the spring 53 is compressed, thereby releasing the movable plate 44, the movable shaft 5 and the lamp body 4. In order to achieve the fixing effect, when the driving motor 26 stops running and the lamp body 4 stops rotating, the controller will cut off the power to the electromagnet assembly 49. At this time, the electromagnet assembly 49 will lose the suction force of the magnet block 54. Due to the elastic recovery effect of the spring 53, the movable plate 51 and the clamping rod 52 can be pushed to move inward along the outer surface of the fixed rod 50, and finally be clamped in the inside of the corresponding clamping hole 45, so that the movable disk 44, the movable shaft 5 and the lamp body 4 can be locked and fixed, thereby strengthening the fixation of the lamp body 4 after the angle adjustment, thereby improving the overall wind resistance of the marine lighting fixture.

[0063] Working principle and usage process:

[0064] When adjustment is required, the controller will energize the electromagnet assembly 49. At this time, the electromagnet assembly 49 will generate suction on the magnet block 54, thereby driving the movable plate 51 and the card rod 52 to move outward along the outer surface of the fixed rod 50, and causing the card rod 52 to disengage from the inside of the card hole 45. At the same time, the spring five 53 is compressed, thereby releasing the fixing effect of the movable plate 44, the movable shaft 5 and the lamp body 4. Due to the operation of the drive motor 26, the rotating shaft 27 can drive the gear 28 and the extrusion disk 12 to rotate. At this time, the gear 28 and the rack 24 are engaged, and the limit block 23 is driven to move to the left through the rack 24, and at the same time, the fixed plate 22 is driven to move to the left along the outer surface of the limit rod 21. The fixed plate 22 can drive the movable rod 20 to move to the left. Due to the movement of the movable rod 20, the movable block 19 can be moved to the left and squeeze the spring two 18. Due to the elastic recovery effect of the spring two 18, the elastic The second spring 18 slowly pushes the second piston 17, causing the second piston 17 to move to the left, and through the second piston 17, the oil inside the cylinder 14 is squeezed and pushed into the interior of the connecting pipe 15, and the one-way valve 16 is squeezed open, the oil is transported to the interior of the liquid cylinder 8, and the piston 11, the connecting rod 9 and the movable block 2 10 are squeezed upward. At the same time, the spring 13 is compressed. Due to the movement of the movable block 2 10, the connecting plate 6, the lamp body 4 and the movable shaft 5 can be pushed to rotate along the interior of the connecting frame 3, and the lighting angle of the lamp body 4 can be adjusted. Due to the rotation of the extrusion disk 12, the extrusion disk 12 can squeeze the rotating shaft 27, the air cylinder 36 and the movable seat 39 to move to the left, and the movable seat 39 can move along the outer surface of the round rod 31. At this time, the push rod 34 and the piston 3 35 will shrink toward the inside of the air cylinder 36, and at the same time compress the spring 4 41 and the spring 3 40. At this time, the baffle 33 can be kept to close the interior of the connecting box 30.

[0065] When it is necessary to adjust the lamp body 4 to the other direction, due to the operation of the drive motor 26, the rotating shaft 27 can drive the gear 28 and the extrusion disk 12 to rotate in the other direction. Due to the rotation of the gear 28, the rack 24, the limit block 23, the fixed plate 22, the moving rod 20 and the moving block 19 can be driven to move to the right, and at the same time, the spring 2 18 and the piston 2 17 are pulled to the right. Since the extrusion disk 12 rotates in the other direction, at this time, due to the elastic recovery effect of the spring 3 40, the moving seat 39 can drive the air cylinder 36 and the push block 37 to move to the right. At the same time, due to the elastic recovery effect of the spring 41, the slider 32, the push rod 34 and the piston 3 35 will move to the left. Due to the flow of the single air hole 42 If the flow rate is less than that of the air hole group 43, resistance will be generated to the movement of the piston three 35, thereby slowly pushing the slider 32 and the baffle 33 to the left. Since there is no resistance to the movement of the moving seat 39, the air cylinder 36 will drive the baffle 33 to move to the right and release the sealing effect inside the connecting box 30. Due to the elastic recovery effect of the spring 13, the piston 11, the connecting rod 9 and the movable block 2 10 can be pushed downward, and the lamp body 4 can be rotated in the other direction. Due to the movement of the piston 11, the oil can be squeezed through the connecting pipe 15 into the interior of the bend 29, and through the bend 29 into the interior of the connecting box 30, and then reflux to the interior of the liquid cylinder 14 through the connecting box 30.

[0066] When the driving motor 26 stops running and the lamp body 4 stops rotating, the controller will cut off the power to the electromagnet assembly 49. At this time, the electromagnet assembly 49 will lose the suction force of the magnet block 54. Due to the elastic recovery effect of the spring 53, the movable plate 51 and the clamping rod 52 can be pushed to move inward along the outer surface of the fixed rod 50, and finally be clamped in the inside of the corresponding clamping hole 45, so that the movable disk 44, the movable shaft 5 and the lamp body 4 can be locked and fixed.
