The top outer wall of the telescopic rod 3 is connected to a second adjustment structure 8, and the protective structure 5 and the first adjustment structure 6 can be pulled up by the second adjustment structure 8, so as to adjust the position and reflection arc of the reflection structure 7, thereby adjusting the lighting structure 2's lighting range and lighting brightness; a protective structure 5, which is located on and connected to the second adjusting structure 8, is used to protect the lighting structure 2 to prevent damage during transportation, and effectively protects the lighting structure 2 during daily storage and transportation to the construction road surface; a first adjusting structure 6, which is located on the inner side of the protective structure 5 and is connected to the protective structure 5, is used to provide an installation position for the reflective structure 7, and also adjusts the curvature of the reflective structure 7 under the mediation of the second adjusting structure 8, thereby adjusting the reflection range of the lighting structure 2; the reflective structure 7, which is located on one side of the first adjusting structure 6 and is connected to the protective structure 5, is used to adjust the illumination range of the lighting structure 2, thereby providing more accurate range illumination for complex road repair pavements.

[0045] When lighting the road to be repaired, the mobile vehicle 1 is transported to the road to be repaired, the telescopic rod 3 is controlled to adjust the lighting structure 2 to a suitable height, and then the second adjustment structure 8 is controlled to unfold the protective structure 5.

After power supply, the reflective structure 7 is adjusted according to the actual construction range, thereby adjusting the irradiation range of the lighting structure 2, so as to facilitate the staff to carry out construction and repair work.

[0046] like Figures 2 to 5As shown, the second adjustment structure 8 includes three support rods 84 fixedly connected to the outer wall of the telescopic rod 3 and distributed at 120° to each other, and the top ends of the three support rods 84 are fixedly connected to the mounting base 83. One end of the three support rods 84 distributed at 120° to each other is fixedly connected to the outer wall of the telescopic rod 3, and the other end extends along the surface of the lampshade 21 to the top of the lampshade 21, thereby supporting and fixing the mounting base 83 to prevent the mounting base 83 from becoming unstable during operation. A motor frame (not shown in the figure) is fixedly connected to the center position of one side of the mounting base 83. The motor frame is composed of three columns and annular plates fixedly connected to the columns. The three columns are respectively fixedly connected to the surface of the mounting base 83, and the annular plate is sleeved and fixed to the outer wall of the dual-axis motor 86, thereby fixing the dual-axis motor 86. The motor frame is fixedly connected with the dual-axis motor 86. The machine 86 can separately control the first winding drum 85 and the second winding drum 87. The output shafts at both ends of the double-axis motor 86 are fixedly connected to the first winding drum 85 and the second winding drum 87 respectively. The surface wall of the first winding drum 85 is evenly fixedly connected with six first traction ropes 81. The double-axis motor 86 drives the first winding drum 85 to rotate, thereby winding and stretching the six first traction ropes 81. During the stretching process, it will drive the first adjustment structure 6 connected to it to move. The surface wall of the second winding drum 87 is evenly fixedly connected with six second traction ropes 82. The outer wall of the mounting base 83 is fixedly connected with three evenly distributed connecting strips. The double-axis motor 86 drives the second winding drum 87 to rotate, thereby winding and stretching the six second traction ropes 82, and drives the protective structure 5 connected to it to rotate on the connecting ring 53, so that the protective structure 5 is unfolded.

[0047] like Figure 6 and Figure 7As shown, the protective structure 5 includes a connecting ring 53 fixedly connected to one end of the connecting strip, the connecting ring 53 is used to connect the six turning strips 52, the surface wall of the connecting ring 53 is sleeved with six evenly distributed turning strips 52, the turning strips 52 are provided with connecting ring holes 56, the turning strips 52 are sleeved on the surface wall of the connecting ring 53 through the connecting ring holes 56, the outer side of the turning strip 52 is fixedly connected with an arc baffle 51, the turning strip 52 and the arc baffle 51 are an integrally formed structure, the six arc baffles 51 are fitted to each other in a ring-shaped distribution in the initial state, the six arc baffles 51 are fitted in a ring-shaped distribution in the initial state, the arc baffle 51 can block the impact of external objects on the lighting structure 2, thereby protecting the lighting structure 2 from damage and breakage caused by external impact, and the six arc baffles 51 distributed in a ring A cover 4 is provided on the top of the arc-shaped baffle plate 51. In the initial state, the cover 4 is provided on the top of the six arc-shaped baffle plates 51 to protect the top of the lighting structure 2. A limiting block 54 is fixedly connected to the top center position of the arc-shaped baffle plate 51. A through hole is provided on the limiting block 54 for the insertion of the second traction rope 82 and to prevent the second traction rope 82 from deviating during the traction process. A traction block 55 is fixedly connected to the bottom end of the arc-shaped baffle plate 51 at a position corresponding to the limiting block 54. One end of the second traction rope 82 passes through the limiting block 54 and extends to one side of the traction block 55 for fixing. When the second traction rope 82 is in the process of winding, it will drive an upward pulling force on the traction block 55 connected thereto, thereby pulling the steering bar 52 on the arc-shaped baffle plate 51 to rotate on the connecting ring 53.

[0048] like Figure 8 and Fig.12As shown, the first adjustment structure 6 includes a connecting rod 63 fixedly connected to one side of the steering bar 52, the connecting rod 63 is fixedly connected to the steering bar 52, and the connecting rod 63 provides installation positions for the first fixed block 62 and the second fixed block 64, and provides a sliding track for the adjustment slider 65. The first fixed block 62 is fixedly connected to the end of the connecting rod 63 close to the steering bar 52, and the second fixed block 64 is fixedly connected to the middle position of the connecting rod 63. The first fixed block 62 is used to reinforce the fixation of the connecting rod 63 and provide an installation position for the reflective plate 71 of the reflective structure 7. The second fixed block 64 is used to further fix the reflective plate 71. The bottom end of the connecting rod 63 is slidably connected to the adjustment slider 65, and the adjustment slider 65 can slide on the connecting rod 63 to adjust One side of the slider 65 is in contact with the reflective plate 71, the first fixed block 62 and the adjusting slider 65 have the same structure and shape, and one side of the first fixed block 62 is fixedly connected to one side of the arc baffle 51, and the side surface of the adjusting slider 65 close to the arc baffle 51 is in contact with the arc baffle 51, and a through traction hole 61 is provided on the first fixed block 62, and one end of the first traction rope 81 extends through the traction hole 61 to one side of the adjusting slider 65 and is fixed. When the first traction rope 81 is wound up, it will pull the adjusting slider 65, so that the adjusting slider 65 slides on the connecting rod 63, and the adjusting slider 65 will squeeze the reflective plate 71 during the sliding process, so that the bottom end position of the reflective plate 71 reflects the bending deformation, thereby adjusting the reflection range of the reflective plate 71.

[0049] like Fig. 9 , Fig.10 and Fig.13As shown, the reflective structure 7 includes a reflective plate 71 fixedly connected to one side of the first fixed block 62 and the second fixed block 64. The reflective plate 71 is an arc-shaped structure, and the reflective plate 71 is made of aluminum material. Its surface is anodized to have good reflective performance, effectively reduce the waste of light, and improve the lighting effect. The top surface of the reflective plate 71 is fixedly connected to one side of the first fixed block 62, and the middle position of one side of the reflective plate 71 is fixedly connected to one side of the second fixed block 64. The bottom surface of the reflective plate 71 is in contact with one side of the adjusting slider 65. A first through groove 73 that runs horizontally through the reflective plate 71 is provided on the reflective plate 71. The first through groove 73 is used to install a hidden extension structure 9. A plurality of rows of evenly distributed weakening grooves 74 are provided on both sides of the bottom end of the first through groove 73. When the adjusting slider 65 squeezes the reflective plate 71 under the traction of the first traction rope 81, the reflective plate 7 The weakened groove 74 opened on 1 can assist the reflector 71 to deform, reduce the tensile force of the first traction rope 81 when pulling, and prevent the first traction rope 81 from breaking during the stretching process, and both ends of the first through-groove 73 are provided with an expansion slide groove, and both ends of the expansion slide groove are fixedly connected with an expansion slide rod, which is used to provide a sliding track for the displacement slide 93 to prevent the displacement slide 93 from deviating during the stretching and sliding. A limiting groove 72 is opened at the top of the reflector 71, and the limiting groove 72 is used to limit the first traction rope 81 to prevent the first traction rope 81 from deviating during the traction process. The first through-groove 73 is connected with an extension structure 9. When the reflector 71 is unfolded along with the first adjustment structure 6, there will be a gap between the reflector plates 71. The gap between the reflector plates 71 can be made up by the extension structure 9, thereby not affecting the reflection of the illumination light of the illumination structure 2.

[0050] like Figure 4 , Fig.11 and Fig.14As shown, the extension structure 9 includes a first extension plate 91 and a second extension plate 92 which are symmetrical to each other and are slidably connected in the first through slot 73. The first extension plate 91 and the second extension plate 92 are symmetrical to each other and independent of each other. The first extension plate 91 and the second extension plate 92 are fixedly connected with displacement slides 93 at both ends of the opposite sides. The displacement slides 93 are sleeved on the unfolding slide rod and slide with each other. A return spring is sleeved on the unfolding slide rod. The return spring is used to squeeze the displacement slide 93 so that after the work is completed, the extruded displacement slide 93 is restored to the initial position. The two ends of the return spring are respectively fixedly connected to one side of the displacement slide 93 and one end of the unfolding slot. A second through slot 95 is provided on the first extension plate 91. The second through slot 95 is used to make the first extension plate 91 The second extension plate 92 has good ductility, and the quality and production cost of the first extension plate 91 and the second extension plate 92 are reduced. An elastic connecting piece 94 is fixedly connected between each second extension plate 92 and the first extension plate 91 in the adjacent reflecting plate 71. The elastic connecting piece 94 is used to connect the adjacent first extension plates 91 and the second extension plates 92. When the first extension plates 91 and the second extension plates 92 are unfolded, the connection position will deviate. Through the ductility of the elastic connecting piece 94 itself, the connection position of the first extension plate 91 and the second extension plate 92 will not be misaligned or broken. The shape formed by the connection of the first extension plate 91 and the adjacent second extension plate 92 is consistent with the shape of the gap between the two adjacent reflecting plates 71 after rotating 75°.

[0051] When the reflector 71 is unfolded, the first extension plate 91 and the second extension plate 92 inside the adjacent reflector plates 71 are pulled under the tensile force of the unfolded reflector 71, so that they slide on the slide rods inside their respective reflector plates 71. During the sliding process, the displacement slide 93 will squeeze the reset spring until the reflector 71 is unfolded to a set angle, and the adjacent first extension plate 91 and the second extension plate 92 are pulled out from the first through groove 73 to fill the gap caused by the unfolding of the reflector 71. When the lighting work is finished and needs to be recovered, the reflector 71 gradually returns to its initial position, and the displacement slides 93 on the first extension plate 91 and the second extension plate 92 are squeezed to the initial position under the restoring deformation force of the reset spring.

[0052] like Figure 5As shown, the lighting structure 2 includes a lamp post 23 fixedly connected to the top of the telescopic rod 3, and a plurality of annular light strips 22 matched with the surface wall of the lamp post 23 are fixedly connected from top to bottom. The annular light strips 22 provide 360° lighting and have a wider illumination angle. The outer sleeve of the lamp post 23 is provided with a lampshade 21, and the lampshade 21 is made of a transparent acrylic plate. The bottom end of the lampshade 21 is fixedly connected to the surface wall of the telescopic rod 3. The lamp post 23 is an annular concave structure, and the concave angle of the top end is greater than the concave angle of the bottom end, so that the illumination angle of the annular light strip 22 at the upper end of the lamp post 23 is biased downward, which can illuminate nearby positions, and the illumination angle of the annular light strip 22 at the lower end is biased upward, which can gather more light on the reflective plate 71 and reflect it through the reflective plate 71, thereby increasing the intensity of the reflected light.

[0053] The working principle of the technical solution provided by the present invention is as follows: when lighting the road to be repaired, the mobile car 1 is transported to the road to be repaired, the telescopic rod 3 is controlled to adjust the lighting structure 2 to a suitable height, and then the second adjustment structure 8 is controlled to unfold the protective structure 5. When unfolding, the dual-axis motor 86 drives the second winding disk 87 to rotate, thereby winding and stretching the six second traction ropes 82. During the winding process, the second traction rope 82 will drive the traction block 55 connected thereto with an upward pulling force, thereby pulling the steering bar 52 on the arc baffle 51 to rotate on the connecting ring 53.

[0054] When the protective structure 5 is unfolded, the first adjustment structure 6 and the reflective structure 7 fixedly connected thereto are also unfolded, thereby exposing the lighting structure 2, and starting the generator to supply power to the lighting structure 2. After power supply, the reflective structure 7 is adjusted according to the actual construction range.

[0055] When adjusting the reflective structure 7, the dual-axis motor 86 drives the first winding drum 85 to rotate, thereby winding and stretching the six first traction ropes 81. When the first traction ropes 81 are wound, they will pull the adjustment slider 65, so that the adjustment slider 65 slides on the connecting rod 63. During the sliding process, the adjustment slider 65 will squeeze the reflective plate 71, so that the bottom end position of the reflective plate 71 reflects the bending deformation, thereby adjusting the reflection range of the reflective plate 71, and then adjusting the illumination range of the lighting structure 2, so as to facilitate the staff to carry out construction and repair work.

[0056] At the same time, when the reflective plate 71 is unfolded along with the arc-shaped baffle plate 51, the first extension plate 91 and the second extension plate 92 inside the adjacent reflective plates 71 are pulled under the tensile force of the unfolding of the reflective plate 71, so that they slide on the sliding rods inside their respective reflective plates 71. During the sliding process, the displacement slide 93 will squeeze the reset spring until the reflective plate 71 is unfolded to the set angle, and the adjacent first extension plate 91 and the second extension plate 92 are pulled out from the first through groove 73 to fill the gap caused by the unfolding of the reflective plate 71.
