Description

Technical Field

[0001] This invention relates to the field of construction site lighting technology, and in particular to a lighting device for intelligent construction sites. Background Technology

[0002] Construction site lighting is crucial during the construction process, playing a key role in ensuring construction safety and quality. Good lighting allows for clear observation of equipment status and the surrounding environment, enabling workers to work normally at night or in low-light conditions, extending effective working time, and thus accelerating construction progress. It also helps workers to promptly identify safety hazards on the construction site and prevent accidents. Especially during nighttime construction, it is necessary to keep the lighting on all the time. Moreover, the outdoor construction site environment is complex, and many factors need to be considered when selecting lighting. Therefore, there is a need for a smart construction site lighting device.

[0003] Existing lighting devices used in smart construction sites are generally installed directly in the outdoor environment via pillars. However, the outdoor environment of construction sites is variable, and the lamps lack effective protection. When they are outdoors for a long time, they are prone to accumulating a lot of dust, which will affect the lighting effect. At the same time, construction site lights are not easy to quickly put away or take away, which will affect their effectiveness. Summary of the Invention

[0004] The purpose of this invention is to provide a lighting device for intelligent construction sites, in order to solve the problems mentioned in the background art. Existing intelligent construction site lighting devices are generally installed directly in the outdoor environment by means of pillars. However, the outdoor environment of construction sites is variable, the lamps lack effective protection performance, and when they are outdoors for a long time, they are prone to accumulating a lot of dust, which will affect the lighting effect. At the same time, construction site lights are not easy to quickly put away and put away, which will affect the use effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lighting device for intelligent construction sites, comprising a housing, a drive wheel rotatably connected to one side of the upper surface of the housing, a central shaft connected to the inner ring bearing of the drive wheel, a connecting shaft fixedly mounted at the lower end of the central shaft, a first bevel gear fixedly mounted at one end of the connecting shaft, a second bevel gear meshing perpendicularly with one side of the first bevel gear, an internally threaded tube fixedly connected to the upper end of the central shaft, an externally threaded tube threadedly connected to one end of the internally threaded tube, a connector welded to one end of the externally threaded tube, a bottom cover rotatably connected to one end of the connector, and first sleeves fixedly mounted on both sides of the surface of the drive wheel. The inner ring of the connector and the external threaded pipe has an internal threaded groove. One end of the internal threaded groove is threadedly connected to a threaded rod. The upper end of the threaded rod is fixedly connected to a top cover. The inner ring surface of the bottom cover is fixedly installed with second sleeves at equal intervals. One end of the second sleeve is connected to a second movable rod. The inner ring surface of the bottom cover adjacent to the second sleeve is fixedly installed with a support rod. One end of the support rod is fixedly connected to a connecting frame. The extension section of the connecting frame has a sliding groove. One end of the sliding groove is provided with a slider. One side surface of the slider is fixedly installed with a first connecting block. One end of the first connecting block is rotatably connected to a connecting rod. The other side surface of the slider is fixedly installed with a lighting lamp.

[0006] Preferably, a first drive motor is fixedly installed on the upper surface of one side of the inner wall of the housing, a synchronous belt is sleeved on the outer ring of the drive wheel, a driven wheel is sleeved on one end of the synchronous belt, and a second drive motor is fixedly installed at the inner partition of the housing.

[0007] Preferably, the output end of the first drive motor passes through the housing and is fixedly connected to the driven wheel, and the output end of the second drive motor passes through the inner partition of the housing and is fixedly connected to the second bevel gear.

[0008] Preferably, a limiting groove is formed on the inner ring surface of the first sleeve, a limiting block is provided at one end of the limiting groove, and a first movable rod is fixedly connected to the upper end of the limiting block.

[0009] Preferably, the upper end of the second movable rod is fixedly connected to the top cover, and the second movable rod and the second sleeve form a telescopic structure. The cooperation structure of the second movable rod and the second sleeve is the same as the cooperation structure of the first sleeve and the first movable rod.

[0010] Preferably, a collar is fitted and fixed at one end of the second movable rod, a second connecting block is welded to one side surface of the collar, and a connecting rod is rotatably connected to one end of the second connecting block.

[0011] Preferably, both the top cover and the bottom cover have corresponding outer rings, and the sliding groove is a T-shaped groove structure.

[0012] Preferably, the thread structure of the internally threaded tube is opposite to the thread structure of the internally threaded groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are: By setting up the drive wheel, the first bevel gear, and the second bevel gear, the drive wheel and the first bevel gear can be driven to rotate by the first drive motor and the second drive motor respectively. At the same time, due to the rotational connection between the connector and the base cover, as well as the rotational connection between the drive wheel and the central shaft, the base cover can rotate in different directions through the drive of the drive wheel and the internal threaded tube.

[0014] By setting up an internally threaded tube, an externally threaded tube, a connector, an internally threaded groove, and a threaded rod, the internally threaded tube rotates while simultaneously rotating at a fixed position on the drive wheel. This causes the externally threaded tube, which is connected by a threaded joint, to rise and fall at one end of the internally threaded tube. The internally threaded tube then drives the bottom cover to rise and fall. At the same time, when the bottom cover rotates in a direction different from that of the internally threaded tube through the rotation of the drive wheel, the threaded rod, due to the threaded structure of the threaded joint and the internally threaded groove, causes the threaded rod to drive the top cover to rise and fall.

[0015] By configuring the second sleeve, the second movable rod, and the connecting frame, and controlling the direction of rotation of the bottom cover, the threaded rod can be raised and lowered at one end of the internal thread groove. When the top cover is raised, it will drive the second movable rod to be raised at one end of the second sleeve. The second movable rod will drive one end of the connecting rod upward, causing the other end of the connecting rod to slide through the slider connected to the first connecting block. The slider will drive the lighting lamp to move, allowing the lighting lamp to be raised and lowered at one end of the connecting frame by raising and lowering the top cover. When the top cover is lowered, the lighting lamp is retracted, and the top cover and bottom cover are in contact and closed, providing dust protection and other protection for the lighting lamp. When the top cover is raised, the lighting lamp is extended to provide illumination. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-8This invention provides a technical solution: a lighting device for intelligent construction sites, comprising a housing 1, a drive wheel 3 rotatably connected to one side of the upper surface of the housing 1, a central shaft 6 connected to the inner ring bearing of the drive wheel 3, a connecting shaft 7 fixedly installed at the lower end of the central shaft 6, a first bevel gear 8 fixedly installed at one end of the connecting shaft 7, a second bevel gear 9 vertically meshing with one side of the first bevel gear 8, an internally threaded pipe 11 fixedly connected to the upper end of the central shaft 6, an externally threaded pipe 12 threadedly connected to one end of the internally threaded pipe 11, a connector 13 welded to one end of the externally threaded pipe 12, a bottom cover 14 rotatably connected to one end of the connector 13, and first sleeves 15 fixedly installed on both sides of the surface of the drive wheel 3, the connector 13 and the externally threaded pipe 12... An internal threaded groove 19 is formed on the inner ring. A threaded rod 20 is threadedly connected to one end of the internal threaded groove 19. A top cover 21 is fixedly connected to the upper end of the threaded rod 20. A second sleeve 22 is fixedly installed at equal intervals on the inner ring surface of the bottom cover 14. A second movable rod 23 is connected through one end of the second sleeve 22. A support rod 24 is fixedly installed on the inner ring surface of the bottom cover 14 near the second sleeve 22. A connecting frame 25 is fixedly connected to one end of the support rod 24. A sliding groove 26 is formed on the surface of the extension section of the connecting frame 25. A slider 27 is provided at one end of the sliding groove 26. A first connecting block 28 is fixedly installed on one side surface of the slider 27. A connecting rod 29 is rotatably connected to one end of the first connecting block 28. A lighting lamp 32 is fixedly installed on the other side surface of the slider 27.

[0020] Furthermore, a first drive motor 2 is fixedly installed on the upper surface of one side of the inner wall of the housing 1. A synchronous belt 4 is fitted around the outer ring of the drive wheel 3, and a driven wheel 5 is fitted around one end of the synchronous belt 4. A second drive motor 10 is fixedly installed in the inner partition of the housing 1. Through the arrangement of the first drive motor 2 and the second drive motor 10, the first drive motor 2 can drive the driven wheel 5 to rotate above the housing 1. The driven wheel 5 drives the drive wheel 3 to rotate through the synchronous belt 4. The rotation of the drive wheel 3 will drive the first sleeve 15 and the first movable rod 18 to rotate. The first movable rod 18 will drive the bottom cover 14 to rotate around the outer ring of the connecting piece 13. The second drive motor 10 can drive the second bevel gear 9 to rotate. The second bevel gear 9 drives the first bevel gear 8 to rotate. The first bevel gear 8 drives the internally threaded tube 11 at the upper end of the central shaft 6 to rotate through the connecting shaft 7. Since the inner ring of the external threaded tube 12 is provided with an internal threaded groove 19, and the internal threaded groove 19 is connected to the top cover 21 through the threaded rod 20, and the top cover 21 is connected to the bottom cover 14 through the second movable rod 23 and the second sleeve 22, the rotation of the bottom cover 14 is controlled by the first drive motor 2, so that the rotation of the threaded rod 20 is controlled by the bottom cover 14. When the bottom cover 13 and the internal threaded tube 11 rotate in opposite directions, due to the friction between themselves and the friction generated between other connecting parts, the threaded rod 20 and the internal threaded tube 11 will generate a force with a resistance effect on each other. Even when the connecting part 13 and the bottom cover 14 are rotated, the external threaded tube 12 will not rotate with the internal threaded tube 11 when the internal threaded tube 11 rotates. Therefore, when the internal threaded tube 11 rotates, the external threaded tube 12 drives the bottom cover 14 to rise and fall without affecting the rotation of the bottom cover 14.

[0021] Furthermore, the output end of the first drive motor 2 passes through the housing 1 and is fixedly connected to the driven wheel 5, and the output end of the second drive motor 10 passes through the inner partition of the housing 1 and is fixedly connected to the second bevel gear 9. Through the setting of the second bevel gear 9, the meshing process of the second bevel gear 9 and the first bevel gear 8 is continuous, the contact state between the tooth surfaces is good, and the power can be effectively transmitted.

[0022] Furthermore, a limiting groove 16 is formed on the inner ring surface of the first sleeve 15, and a limiting block 17 is provided at one end of the limiting groove 16. A first movable rod 18 is fixedly connected to the upper end of the limiting block 17. Through the setting of the first movable rod 18, the first movable rod 18 slides at one end of the limiting groove 16 through the limiting block 17. When the bottom cover 14 is raised or lowered, the first movable rod 18 can extend or retract at one end of the first sleeve 15, and the limiting block 17 can limit the travel distance of the displacement.

[0023] Furthermore, the upper end of the second movable rod 23 is fixedly connected to the top cover 21. The second movable rod 23 and the second sleeve 22 form a telescopic structure. The cooperation structure of the second movable rod 23 and the second sleeve 22 is the same as the cooperation structure of the first sleeve 15 and the first movable rod 18. With the setting of the second movable rod 23, the second movable rod 23 can also slide at one end of the second sleeve 22. By rotating the bottom cover 14, the threaded rod 20 at one end of the top cover 21 is driven to rotate at one end of the internal thread groove 19 to perform lifting and lowering.

[0024] Furthermore, a collar 30 is fixedly fitted onto one end of the second movable rod 23, and a second connecting block 31 is welded to one side surface of the collar 30. A connecting rod 29 is rotatably connected to one end of the second connecting block 31. Through the setting of the connecting rod 29, the connecting rod 29 can push the lighting lamp 32 on one side of the slider 27 to move back and forth by raising and lowering the second movable rod 23.

[0025] Furthermore, the outer rings of the top cover 21 and the bottom cover 14 are both provided with corresponding outer rings, and the slide groove 26 is a T-shaped groove structure. Through the setting of the slide groove 26, the slide groove 26 can limit the movement of the slider 27, so that the lighting lamp 32 can maintain linear movement.

[0026] Furthermore, the thread structure of the internal threaded tube 11 is opposite to that of the internal threaded groove 19. With the internal threaded tube 11 and the internal threaded groove 19, when the internal threaded tube 11 rotates, the external threaded tube 12 will rotate in the opposite direction, allowing the external threaded tube 12 to extend and retract. Similarly, the internal threaded groove 19 and the external threaded tube 12 are an integral structure. Because the internal threaded tube 11 and the external threaded tube 12 rotate in opposite directions, and the threaded rod 20 rotates in a different direction than the internal threaded tube 11, they can each extend and retract at both ends of the external threaded tube 12 under the corresponding threaded engagement.

[0027] Working principle: First, when lighting is needed, the second drive motor 10 drives the first bevel gear 8 at one end of the second bevel gear 9 to rotate. The first bevel gear 8 drives the internal threaded tube 11 to rotate through the connecting shaft 7 and the central shaft 6. At the same time, the first drive motor 2 drives the driven wheel 5 to rotate. The driven wheel 5 drives the driving wheel 3 to rotate through the synchronous belt 4. The driving wheel 3 and the internal threaded tube 11 rotate in opposite directions. The first sleeves 15 on both sides of the upper surface of the driving wheel 3 drive the first movable rod 18 to rotate. The bottom cover 14 rotates, and simultaneously, the bottom cover 14 drives the top cover 21 to rotate via the second sleeve 22 and the second movable rod 23. The top cover 21 drives the threaded rod 20 to rotate in the opposite direction to the internal threaded tube 11. The threaded rod 20 and the internal threaded tube 11 rotate simultaneously at both ends of the external threaded tube 12. The threaded rod 20 engages with the internal thread groove 19. Since the thread structure of the internal thread groove 19 and the internal threaded tube 11 is opposite, when the rotation direction of the threaded rod 20 is the same as that of the external threaded tube 12, it is opposite to the rotation direction of the internal threaded tube 11. When the internal threaded tube 11 remains in a fixed rotational position, the external threaded tube 12 is lifted at one end of the internal threaded tube 11, raising the bottom cover 14 via the connector 13. Simultaneously, the first movable rod 18 connected to the bottom cover 14 slides upward at one end of the first sleeve 15. When the limiting block 17 abuts against the upper inner side of the first sleeve 15, the bottom cover 14 completes its lifting. As the bottom cover 14 continues to rotate, the external threaded tube 12, due to the action of the limiting block 17, has reached a fixed position and cannot be raised further. When rotation continues... When the bottom cover 14 is in operation, the top cover 21 above the bottom cover 14 drives the threaded rod 20 to continue rotating. When the threaded rod 20 rotates at one end of the external threaded tube 12, it drives the top cover 21 to lift upward. When the top cover 21 lifts, it drives the second movable rod 23 to lift upward at one end of the second sleeve 22. At the same time, the second movable rod 23 drives the connecting rod 29 to lift. The other end of the connecting rod 29 drives the slider 27 to slide from the inside to the outside at one end of the connecting frame 25 through the first connecting block 28, thereby causing the lighting lamp 32 on the other side of the slider 27 to be exposed for illumination.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
