Detailed Embodiments

[0025] As Figure 1 shown, and in combination with Figures 2 - 5As shown in the figure, the lighting device for construction engineering of the present invention includes a support rod 10 arranged vertically. A linkage shaft 12 is slidably arranged vertically on the support rod 10. The lower end of the linkage shaft 12 is connected to a braking assembly 2 slidably arranged vertically on the support rod 10. The upper end of the linkage shaft 12 is hinged to one end (the lower end shown in the figure) of a push-pull plate 14 through a pin shaft. The other end of the push-pull plate 14 faces upward and is inclined away from the support rod 10. The other end (the upper end shown in the figure) of the push-pull plate 14 is hinged to the upper end of a lighting assembly 22 through a pin shaft. The lower end of the lighting assembly 22 is hinged to the support rod 10. When the braking assembly 2 drives the linkage shaft 12 to slide vertically, the linkage shaft 12 drives the lighting assembly 22 to rotate around its hinge point with the support rod 10 (i.e., the movable shaft 17 described below) through the push-pull plate 14.

[0026] As Figure 4 shown, and in combination with Figure 1 、 2 shown, the lighting device for construction engineering of the present invention further includes an erasing assembly 30. The erasing assembly 30 includes a strip-shaped flipping member hinged to the support rod 10 through a pin shaft. The hinge point of the strip-shaped flipping member and the support rod 10 is located between the two ends of the strip-shaped flipping member. One end of the strip-shaped flipping member is hinged to one end of an electric push rod 23 through a pin shaft. The other end of the electric push rod 23 is hinged to the support rod 10 through a pin shaft. A wiping member extending to the lighting assembly 22 is slidably arranged at the other end of the strip-shaped flipping member. A first elastic member 27 is arranged between the wiping member and the strip-shaped flipping member. The wiping member abuts against the lighting assembly 22 under the action of the first elastic member 27. When the electric push rod 23 drives the strip-shaped flipping member to rotate around its hinge point with the support rod 10, the wiping member can move along the lighting assembly 22.

[0027] When the lighting assembly 22 is used in summer, due to its relatively high temperature, it is very easy to stick the corpses of flying insects, thus affecting the lighting effect. Therefore, the present invention adds an erasing assembly 30 to remove the corpses of flying insects on the lighting assembly 22.

[0028] The electric push rod 23 is a prior art and can perform telescopic movement. Its specific structure and working principle will not be elaborated here. When the electric push rod 23 performs telescopic movement, it can drive the strip-shaped flipping member to rotate around its hinge point with the support rod 10. Then, the wiping member slidably arranged at the other end of the strip-shaped flipping member rotates together with the strip-shaped flipping member. At the same time, since the wiping member abuts against the lighting assembly 22 under the action of the first elastic member 27, the wiping member can move along the lighting assembly 22 to remove the corpses of flying insects on it.

[0029] As Figure 1 、 2As shown, the lighting device for construction engineering of the present invention, wherein the support rod 10 includes two relatively arranged and spaced-apart sub-support rods 11, both of the two sub-support rods 11 are arranged vertically, and a top plate is fixedly connected between the upper ends of the two sub-support rods 11, that is, the support rod 10 is in an inverted U shape. The lower end of the linkage shaft 12 slides downward through the top plate and is connected to a braking assembly 2 slidably arranged vertically on the two sub-support rods 11. The upper end of the linkage shaft 12 is fixedly provided with a first push plate 13, and one end of a push-pull plate 14 is hinged to the first push plate 13 on the upper end of the linkage shaft 12 through a pin shaft.

[0030] A first through hole for accommodating the linkage shaft 12 is formed in the top plate. The linkage shaft 12 is arranged vertically, and the lower end of the linkage shaft 12 passes through the first through hole. There is a clearance fit between the linkage shaft 12 and the first through hole. In this way, the linkage shaft 12 can slide vertically in the first through hole, that is, the purpose of the above-mentioned linkage shaft 12 being slidably arranged vertically on the support rod 10 is achieved. The upper end of the linkage shaft 12 is located above the top plate (i.e., above the support rod 10), and the lower end of the push-pull plate 14 is hinged to the first push plate 13 at the upper end of the linkage shaft 12, so the push-pull plate 14 is also located above the top plate.

[0031] As Figure 3 shown, and in combination with Figure 1 , 2 shown, the lighting device for construction engineering of the present invention, wherein the lighting assembly 22 includes a lighting device 19 arranged vertically. The non-illuminating side of the lighting device 19 is fixedly arranged on one side of a mounting plate 15 arranged vertically. A support plate 35 is fixedly provided at the upper end and the lower end of this side of the mounting plate 15 respectively, so that the non-illuminating side of the lighting device 19 is fixedly arranged between the two support plates 35. The other end of the push-pull plate 14 is hinged to the upper end of the other side of the mounting plate 15 through a pin shaft. The lower end of the mounting plate 15 is fixedly connected with a movable shaft 17 arranged horizontally through a connecting plate 16, that is, the connecting plate 16 is fixedly arranged on the support plate 35 at the lower end of the mounting plate 15, and the movable shaft 17 is fixedly connected to the connecting plate 16. Both ends of the movable shaft 17 are respectively hinged between one ends of two fixing plates 18, and the other ends of the two fixing plates 18 are respectively fixedly arranged on the two sub-support rods 11. Hinge holes are provided at one ends of the two fixing plates 18, and both ends of the movable shaft 17 are respectively inserted into the two hinge holes. There is a clearance fit between the movable shaft 17 and the hinge holes, that is, the movable shaft 17 can rotate in the hinge holes, so both ends of the movable shaft 17 are hinged between one ends of the two fixing plates 18. The linkage shaft 12 can drive the lighting assembly 22 to rotate around the movable shaft 17 through the push-pull plate 14.

[0032] The wiping member abuts against the lighting side of the lighting device 19 under the action of the first elastic member 27. When the electric push rod 23 drives the strip-shaped flipping member to rotate around its hinge joint with the support rod 10, the wiping member can move along the lighting side. Specifically, an outwardly expanding portion 20 is provided on the lighting side of the lighting device 19. A transparent plate 38 is provided in the outwardly expanding portion 20. The transparent plate 38 is made of a glass plate. The transparent plate 38 is arranged opposite to the lighting side of the lighting device 19. The wiping member abuts against the transparent plate 38 under the action of the first elastic member 27. When the electric push rod 23 drives the strip-shaped flipping member to rotate around its hinge joint with the support rod 10, the wiping member can move along the transparent plate 38. Opposite sides of the outwardly expanding portion 20 are respectively fixedly provided with a blocking plate 21, and the two blocking plates 21 are arranged along the moving direction of the wiping member.

[0033] An electric lamp 32 is installed on the lighting side of the lighting device 19. The electric lamp 32 is located within the outwardly expanding portion 20. The transparent plate 38 is provided within the outwardly expanding portion 20 and is arranged opposite to the electric lamp 32, that is, the transparent plate 38 covers the electric lamp 32 within the outwardly expanding portion 20. The outwardly expanding portion 20 is in the shape of a tapered square tube. Its small-mouth end is fixedly provided on the lighting side of the lighting device 19, and a transparent plate 38 is fixedly provided within its large-mouth end. The wiping member moving along the transparent plate 38 can remove the adhered dead insects on it. In order to prevent the wiping member from slipping off the outwardly expanding portion 20 during the process of moving along the transparent plate 38, opposite sides of the outwardly expanding portion 20 are respectively fixedly provided with a blocking plate 21 along the moving direction of the wiping member on the transparent plate 38. In this way, the wiping member can move back and forth between the two blocking plates 21 and will not slip off the outwardly expanding portion 20.

[0034] As Figure 4 shown, and in combination with Figure 1 、 2As shown in the figure, the lighting device for construction engineering of the present invention, wherein the strip-shaped flipping member includes a strip-shaped flipping plate 24 and two fixed columns 25. One end of the strip-shaped flipping plate 24 is hinged to one end (the upper end shown in the figure) of the electric push rod 23 through a pin shaft. The other end of the strip-shaped flipping plate 24 is hinged to a support plate 31 through a pin shaft. The support plate 31 is strip-shaped and arranged vertically. The other end of the strip-shaped flipping plate 24 is hinged to the upper end of the support plate 31. The lower end of the support plate 31 is fixedly arranged on the support rod 10. The other end of the strip-shaped flipping plate 24 is fixedly connected to one end of the two fixed columns 25. The two fixed columns 25 are arranged along the length direction of the strip-shaped flipping plate 24. The two fixed columns 25 are parallel to each other and arranged at intervals. The strip-shaped flipping member is arranged horizontally, that is, the strip-shaped flipping plate 24 and the two fixed columns 25 are both arranged horizontally. The strip-shaped flipping plate 24 is hinged to the upper end of the support plate 31, and the lower end of the support plate 31 is fixedly connected to the support rod 10, so that the strip-shaped flipping member is hinged to the support rod 10. A baffle 28 is fixedly connected between the other ends of the two fixed columns 25. The wiping member includes a sliding plate 26, a stabilizing plate 33, a mounting shaft 34 and a wiping cotton 29. The sliding plate 26 is slidably arranged on the two fixed columns 25. First elastic members 27 are respectively sleeved on the two fixed columns 25 between the sliding plate 26 and the baffle 28. The sliding plate 26 is fixedly connected to one end of the stabilizing plate 33. The stabilizing plate 33 is strip-shaped. The other end of the stabilizing plate 33 extends in a direction away from the flipping plate 24. The stabilizing plate 33 is arranged parallel to the fixed column 25. The other end of the stabilizing plate 33 is fixedly connected to a mounting shaft 34. The mounting shaft 34 is located on the side of the stabilizing plate 33 away from the two fixed columns 25. The mounting shaft 34 is arranged horizontally and perpendicular to the stabilizing plate 33. The wiping cotton 29 is sleeved on the mounting shaft 34. The wiping cotton 29 abuts against the transparent plate 38 under the elastic pushing action of the first elastic member 27.

[0035] As Figure 1 , 2As shown in the figure, the relative position relationship between the strip-shaped flipping member and the support rod 10 can be described as follows: the strip-shaped flipping member is located above the support rod 10 and there is a certain distance between them. The support plate 31 is connected between the strip-shaped flipping member and the support rod 10. The upper end of the support plate 31 is hinged to the strip-shaped flipping member, and the lower end of the support plate 31 is fixedly arranged on the support rod 10. And the strip-shaped flipping plate 24 and the two fixing columns 25 are respectively located on the opposite sides of the support rod 10. The upper end (i.e., one end of the electric push rod 23 mentioned above) of the electric push rod 23 is hinged to the strip-shaped flipping plate 24, and the lower end (i.e., the other end of the electric push rod 23 mentioned above) of the electric push rod 23 is hinged to the support rod 10. When the electric push rod 23 makes a telescopic movement, the strip-shaped flipping member rotates around its hinge point with the support rod 10, that is, the strip-shaped flipping plate 24 rotates upward or downward, and at the same time the two fixing columns 25 rotate downward or upward. Then the wiping members installed on the two fixing columns 25 also rotate downward or upward.

[0036] Since the lighting device 19 is arranged vertically, the lighting side thereof and the transparent plate 38 installed on this side are also arranged vertically. And the mounting shaft 34 of the wiping member is arranged horizontally and the wiping cotton 29 thereon abuts against the transparent plate 38. And the mounting shaft 34 rotates downward or upward together with the fixing column 25, that is, makes a circular motion, as Figure 6 shown in the figure. Point O is the hinge point between the strip-shaped flipping member and the support plate 31, specifically the hinge point between the strip-shaped flipping plate 24 and the support plate 31. Points A and B are both two points on the transparent plate 38. Point A is located above point B, and OA is arranged horizontally. When the mounting shaft 34 rotates downward together with the fixing column 25 from the horizontal direction, that is, when the mounting shaft 34 moves from point A to point B of the transparent plate 38, since the distance from point A to point O is less than the distance from point B to point O, in order to make the mounting shaft 34 reach point B, the wiping member must be able to slide along the fixing column 25 so that the distance from the mounting shaft 34 to point O can become larger. However, if the first elastic member 27 is not installed, when the mounting shaft 34 returns from point B to point A, the distance from itself to point O will not become smaller. Then the mounting shaft 34 will not contact the transparent plate 38, and the wiping cotton 29 will not be able to wipe the transparent plate 38. Therefore, the first elastic member 27 is added to make the mounting shaft 34 contact the transparent plate 38 when moving back and forth between point A and point B, that is, the wiping cotton 29 on the mounting shaft 34 can abut against the transparent plate 38 to wipe it. Combining Figure 4As shown, when the mounting shaft 34 is located at point A, a pre-compressive force is applied to the first elastic member 27. At this time, under the pushing force of the elastic force of the first elastic member 27, the sliding plate 26 slides along the fixed column 25 close to the flipping plate 24, that is, the entire wiping member slides close to point O. Thus, the erasing cotton 29 on the mounting shaft 34 can abut against the transparent plate 38. When the mounting shaft 34 moves from point A to point B, since the distance between OA is less than the distance between OB, the mounting shaft 34 gradually moves away from point O, that is, the wiping member slides along the fixed column 25 away from the flipping plate 24, so that the mounting shaft 34 can reach point B. During this process, the sliding plate 26 slides close to the baffle 28 and compresses the first elastic member 27 (since the first elastic member 27 is provided between the sliding plate 26 and the stop block, the first elastic member 27 can be compressed). That is, from point A to point B, the first elastic member 27 is gradually compressed, which means that the first elastic member 27 is always in a compressed state. Then, under the pushing force of the elastic force of the first elastic member 27, the entire wiping member always has a tendency to slide close to point O. Thus, the erasing cotton 29 on the mounting shaft 34 can always abut against the transparent plate 38 during the process of moving from point A to point B. When the mounting shaft 34 rotates upward together with the fixed column 25, the principle is the same as that of rotating downward together with the fixed column 25 as described above, so it will not be elaborated here.

[0037] As Figure 5 shown, and in combination with Figure 1 、 2 shown, the lighting device for construction engineering of the present invention, wherein the braking assembly 2 includes an adjusting plate 3, the adjusting plate 3 is slidably arranged vertically on two sub-supporting rods 11, a bearing plate 6 is fixedly arranged on the adjusting plate 3, the adjusting plate 3 is arranged horizontally, the bearing plate 6 is arranged vertically, the bearing plate 6 is opposite to and spaced apart from the two sub-supporting rods 11, a plurality of card slots 9 opposite to the bearing plate 6 are arranged on both sub-supporting rods 11, and the plurality of card slots 9 are evenly spaced vertically on the sub-supporting rods 11. A pull column 5 is slidably penetrated through the bearing plate 6, one end of the pull column 5 is located between the bearing plate 6 and the card slot 9, the other end of the pull column 5 slides through the bearing plate 6, a clamping plate 8 is fixedly arranged at one end of the pull column 5, and a second elastic member 36 is sleeved on the pull column 5 between the clamping plate 8 and the bearing plate 6. The clamping plate 8 is clamped in the card slot 9 under the pushing force of the elastic force of the second elastic member 36, and the lower end of the linkage shaft 12 is connected to the adjusting plate 3.

[0038] In the lighting device for construction engineering of the present invention, two pull columns 5 are provided, the clamping plate 8 is fixedly arranged at one end of the two pull columns 5, and a pull rod 4 is fixedly connected between the other ends of the two pull columns 5. The clamping plate 8 is fixedly arranged on the second top-pushing plate 7, the second top-pushing plate 7 is fixedly arranged at one end of the two pull columns 5, and the second top-pushing plate 7 abuts against the adjusting plate 3 and can slide along the adjusting plate 3.

[0039] There are two second through holes 37 provided on the adjusting plate 3, and two sub-support rods 11 are respectively inserted into the two second through holes 37. There is a clearance fit between the sub-support rod 11 and the second through hole 37, so that the adjusting plate 3 can slide vertically along the two sub-support rods 11, that is, the adjusting plate 3 is vertically slidably arranged on the two sub-support rods 11. There are two third through holes provided on the bearing plate 6, and two pull-out columns 5 are respectively inserted into the two third through holes. There is a clearance fit between the pull-out column 5 and the third through hole, so that the pull-out column 5 can slide relative to the bearing plate 6, that is, the pull-out column 5 is slidably inserted into the bearing plate 6.

[0040] A pre-compressive force is applied to the second elastic member 36. In this way, under the elastic pushing action of the second elastic member 36, the second top plate 7 slides away from the bearing plate 6 along the adjusting plate 3, that is, the second top plate 7 drives the clamping plate 8 to slide close to the card slot 9 until the clamping plate 8 is clamped in the card slot 9, so that the entire braking assembly 2 is fixed on the sub-support rod 11. When it is necessary to push or pull the linkage shaft 12 upward or downward by the braking assembly 2, hold the pull rod 4 and let the pull-out column 5 slide along the bearing plate 6 in a direction away from the sub-support rod 11. Then the clamping plate 8 withdraws from the card slot 9, and the second top plate 7 compresses the second elastic member 36. After that, slide the adjusting plate 3 upward or downward along the sub-support rod 11. During this process, the linkage shaft 12 connected to the adjusting plate 3 also slides upward or downward along the top plate. When the linkage shaft 12 slides to the required position, at this time, the adjusting plate 3 drives the clamping plate 8 to come to other card slots 9 above or below the original card slot 9 where it is clamped. Release the pull rod 4. Under the elastic pushing action of the second elastic member 36, the second top plate 7 drives the clamping plate 8 to slide close to the card slot 9 again until the clamping plate 8 is clamped in the other card slot 9, and the entire braking assembly 2 is fixed on the sub-support rod 11 again.

[0041] Both the first elastic member 27 and the second elastic member 36 are springs. In order to facilitate the placement of the lighting device, the two sub-support rods 11 are installed on a bottom plate 1, that is, the lower ends of the two sub-support rods 11 are fixedly connected to the bottom plate 1.

[0042] As Figure 1 、 2 shown, for the lighting device for construction engineering of the present invention, two sets of lighting assemblies 22 are provided, and the two sets of lighting assemblies 22 are respectively located on opposite sides of the support rod 10, that is Figure 1On the left and right sides as shown, there are two push-pull plates 14, and the two push-pull plates 14 are also respectively located on the left and right sides of the support rod 10. One end (i.e., the lower end shown in the figure) of the two push-pull plates 14 is hinged to the first push plate 13, and the other ends (i.e., the upper ends shown in the figure) of the two push-pull plates 14 are respectively hinged to the upper ends of two sets of lighting components 22. There are two sets of erasing components 30, and the two sets of erasing components 30 are arranged in one-to-one correspondence with the two sets of lighting components 22. The erasing parts in the two sets of erasing components 30 can move along their respective corresponding lighting components 22.

[0043] As Figure 1 shown, the first set of erasing component 30 is installed on the front side of the support rod 10, and it is arranged in correspondence with the lighting component 22 on the right side of the support rod 10. The erasing part in the first set of erasing component 30 can move along the lighting component 22 on the right side, that is, the mounting shaft 34 in the erasing part moves up and down along the transparent plate 38 in the lighting component 22 on the right side. In this way, the erasing cotton 29 on the mounting shaft 34 can wipe the transparent plate 38 to remove the dead insects on it. The second set of erasing component 30 is installed on the rear side of the support rod 10, and it is arranged in correspondence with the lighting component 22 on the left side of the support rod 10. The erasing part in the second set of erasing component 30 can move along the lighting component 22 on the left side, that is, the mounting shaft 34 in the erasing part moves up and down along the transparent plate 38 in the lighting component 22 on the left side. In this way, the erasing cotton 29 on the mounting shaft 34 can wipe the transparent plate 38 to remove the dead insects on it.

[0044] When the lighting device for construction engineering of the present invention is in use, the braking component 2 slides vertically along the support rod 10, that is, the clamping block is withdrawn from the card slot 9, and then the adjusting plate 3 is slid up and down along the support rod 10. Since the linkage shaft 12 is fixedly connected to the adjusting plate 3, the braking component 2 drives the linkage shaft 12 to slide vertically, and the linkage shaft 12 applies a thrust or a pulling force to the upper end of the lighting component 22 through the push-pull plate 14 (when the linkage shaft 12 slides upward, a thrust away from the support rod 10 is applied to the upper end of the lighting component 22 through the push-pull plate 14; conversely, when the linkage shaft 12 slides downward, a pulling force close to the support rod 10 is applied to the upper end of the lighting component 22 through the push-pull plate 14). Since the lower end of the lighting component 22 is hinged to the support rod 10, the lighting component 22 can rotate around its hinge point with the support rod 10 (i.e., the movable shaft 17). Specifically, when a thrust away from the support rod 10 is applied to the upper end of the lighting component 22, the upper end of the lighting component 22 moves away from the support rod 10 and rotates downward; conversely, when a pulling force close to the support rod 10 is applied to the upper end of the lighting component 22, the upper end of the lighting component 22 moves close to the support rod 10 and rotates upward, so as to achieve the purpose of adjusting the lighting angle. After the lighting component 22 rotates to the required lighting angle, stop the braking component 2 from sliding along the support rod 10, and then fix the braking component 2 on the support rod 10, that is, snap the clamping plate 8 into the card slot 9, so as to fix the lighting angle of the lighting component 22. In addition, the erasing component 30 in the present invention can also wipe the lighting component 22 to avoid the influence of sundries such as the corpses of flying insects on the transparent plate 38 on the lighting effect, so as to ensure the normal construction of the construction project.

[0045] The electric push rod 23 can be controlled to extend and retract through a remote control, that is, a wireless receiving end is arranged in the electric push rod 23, and the wireless receiving end is adapted to the wireless output end on the remote control, so that the extension and retraction of the electric push rod 23 can be controlled through the remote control, that is, the wiping member is controlled to wipe the lighting component 22.
