Detailed Implementation

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Reference Figure 1 , Figure 2 A construction lighting device includes a vertically installed support column 1, which can be lowered into a maintenance well. The bottom of the support column 1 is equipped with a lighting lamp 2, a camera 3, and an oxygen concentration sensor 4. The lighting lamp 2 can provide illumination, the camera 3 can capture images of the environment inside the well, and the oxygen concentration sensor 4 can detect and monitor the oxygen concentration inside the well.

[0036] In this embodiment, camera 3 can be connected to a display on an external system, allowing other personnel on the surface to view the underground environment. Simultaneously, oxygen concentration sensor 4 can also be connected to an external system, enabling timely alerts or rescue efforts to be initiated when low oxygen concentrations are detected inside the maintenance well.

[0037] Reference Figure 1 , Figure 3Multiple lower support arms 5 are hinged to the lower end of the side wall of the support column 1, and the multiple lower support arms 5 are arranged at equal intervals along the circumference of the support column 1. An adjustment part 6 is movably provided at the upper end of the support column 1, and multiple upper support arms 7 are hinged to the adjustment part 6. The multiple upper support arms 7 correspond one-to-one with the multiple lower support arms 5, and the upper support arms 7 and the corresponding lower support arms 5 are hinged to each other through a hinge shaft 8.

[0038] Reference Figure 1 , Figure 3 Each lower support arm 5 is equipped with a support rod 9, and each support rod 9 is rotatably connected to a traveling wheel 10 at its end. The adjustment part 6 can move at least in the vertical direction to allow the upper support arm 7 to open or retract with the corresponding lower support arm 5, and to allow the traveling wheel 10 to abut or separate from the well wall of the maintenance well. At the same time, a locking element 11 is provided on the support column 1 to fix the adjustment part 6.

[0039] Before maintenance work begins, support column 1 is lowered into the well. Then, control adjustment unit 6 moves downward, spreading multiple upper support arms 7 and lower support arms 5 until multiple traveling wheels 10 abut against the well wall. Subsequently, lighting equipment is lowered into the well. At this time, lighting lamp 2 provides illumination, camera 3 captures images of the well environment, and oxygen concentration sensor 4 detects the oxygen concentration inside the well.

[0040] Subsequently, the lighting device was removed from the inspection well. After the construction workers entered the well, the lighting device was lowered back into the well. At this time, the lighting device 2 could illuminate the inside of the well, thereby improving the lighting effect. At the same time, the camera 3 filmed the construction workers and the environment inside the well, and the oxygen concentration sensor 4 monitored the oxygen concentration inside the well. In case of an accident, external personnel could carry out rescue in a timely manner.

[0041] Reference Figure 1 , Figure 3 The adjusting part 6 includes an adjusting ring 61 and a receiving ring 62. The receiving ring 62 is rotatably sleeved on the adjusting ring 61, and the adjusting ring 61 is movably sleeved on the support column 1. A locking member 11 is used to fix the adjusting ring 61. The locking member 11 includes locking threads 111 respectively provided on the adjusting ring 61 and the support column 1, and the two locking threads 111 cooperate to fix the adjusting ring 61 in the vertical direction. A pair of adjusting handles 63 are fixedly connected to the top of the adjusting ring 61. Rotating the adjusting handles 63 drives the adjusting ring 61 to rotate, and then the adjusting ring 61 drives the receiving ring 62 to move vertically, thereby realizing the control of the upper support arm 7 and the lower support arm 5 to open or retract.

[0042] Reference Figure 3 , Figure 4The support rod 9 and the corresponding lower support arm 5 are hinged together by a pin 12. A torsion spring 13 is provided on the pin 12, and the torsion spring 13 is used to control the support rod 9 to rotate away from the support column 1. When the upper support arm 7 and the lower support arm 5 are spread apart and the traveling wheel 10 abuts against the well wall, the spreading range of the upper support arm 7 and the lower support arm 5 is appropriately increased, that is, the support rod 9 swings toward the support column 1, and the torsion spring 13 is kept in a compressed state.

[0043] When the lighting device is lowered into the well, if there is a change in diameter or pits in the well wall, the support rod 9 can control the swing of the traveling wheel 10 under the elastic force of the torsion spring 13, and keep the traveling wheel 10 in close contact with the well wall. In other words, the traveling wheel 10 can swing according to the changes in the well wall, which can improve the adaptability and stability of use.

[0044] Reference Figure 3 , Figure 4 Each support rod 9 is hinged with a tensioning rod 14, and each upper support arm 7 has a guide groove 15 on its side wall. A guide block 16 is slidably connected in the guide groove 15, and the sliding direction of the guide block 16 is parallel to the length direction of the upper support arm 7. At the same time, the tensioning rod 14 is hinged to the corresponding guide block 16, and a spring 17 is provided in the guide groove 15. The spring 17 is used to push the guide block 16 to slide toward the corresponding hinge axis 8.

[0045] In this design, the elastic force of spring 17 acts on support rod 9 through clamping rod 14. That is, the elastic force of spring 17 and the elastic force of torsion spring 13 work together on support rod 9 to keep traveling wheel 10 in close contact with the well wall. At the same time, when a large pit appears in the well wall, support rod 9 can swing quickly, causing traveling wheel 10 to quickly come into contact with the well wall.

[0046] Reference Figure 1 , Figure 3 A forward and reverse motor 18 is fixedly connected to the support rod 9. The output shaft of the forward and reverse motor 18 is coaxially fixedly connected to the rotation shaft of the walking wheel 10. This design allows workers to enter the well under the control of the ground lighting device, improving the convenience of operation.

[0047] Reference Figure 1 , Figure 3 The top of the support column 1 is provided with a storage slot 19, and a mobile power supply 20 is inserted into the storage slot 19. The wires of multiple forward and reverse motors 18 are respectively connected to the mobile power supply 20 through connectors. The top of the mobile power supply 20 is fixedly fitted with a limiting ring 21, and the limiting ring 21 is connected to the support column 1 by a buckle.

[0048] Reference Figure 3 , Figure 5The support column 1 has a receiving groove 22 on its side wall, and a receiving box 23 is horizontally slidably connected in the receiving groove 22. The side wall of the support column 1 located on the side of the groove opening of the receiving groove 22 has multiple vent holes 24. A receiving tube 25 is vertically fixedly connected to the top wall of the receiving box 23. A sealing cap 26 is provided at the bottom end of the receiving tube 25. Sodium peroxide powder is placed in the receiving tube 25, and clean water is placed in the receiving box 23.

[0049] Reference Figure 3 , Figure 5 The receiving box 23 is equipped with a control component 27, which controls the downward movement of the sealing cover 26 and opens the bottom port of the receiving tube 25. At this time, the sodium peroxide powder in the receiving tube 25 falls down and reacts with water to generate oxygen. The oxygen is then discharged through multiple vent holes 24 and enters the maintenance well to provide emergency oxygen supply to the construction personnel.

[0050] Reference Figure 3 , Figure 5 The control component 27 includes a support frame 271 fixed inside the housing 23. An electric push rod 272 is fixedly connected to the support frame 271. The telescopic end of the electric push rod 272 is fixedly connected to the lower surface of the sealing cover 26. A controller 273 is provided on the support column 1. The oxygen concentration sensor 4 and the electric push rod 272 are respectively connected to the controller 273.

[0051] When the oxygen concentration sensor 4 detects that the oxygen concentration in the well is lower than the preset value, it sends a detection signal to the controller 273. The controller 273 then controls the telescopic end of the electric actuator 272 to move downwards, automatically opening the bottom port of the receiving tube 25. This design enables automated oxygen production in emergencies, providing more timely assistance and protecting construction personnel. Alternatively, an alarm can be wirelessly connected to the ground via Bluetooth. When the controller 273 activates the electric actuator 272, the alarm is simultaneously activated to alert personnel on the ground.

[0052] Reference Figure 5 , Figure 6 The upper surface of the sealing cap 26 is arched to allow sodium peroxide to fall smoothly, reducing the risk of sodium peroxide accumulating on the sealing cap 26 and increasing oxygen production. Simultaneously, an elastic sealing ring 28 is fixedly connected to the edge of the sealing cap 26, and a sealing groove 29 that mates with the sealing ring 28 is provided at the bottom end of the receiving tube 25 to improve the sealing effect and reduce the risk of sodium peroxide deliquescence.

[0053] Reference Figure 5The top of the container 23 has a filling port 30 that communicates with the receiving tube 25, and the filling port 30 is internally threaded with a flexible sealing plug 31. Because the container 23 is detachable, sodium peroxide and water can be added, allowing the oxygen generator to be reused. In this embodiment, the container 23 and the support column 1 can be connected by screws or clips to prevent separation of the container 23 and the support column 1.

[0054] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
