Description

Technical Field

[0001] This utility model relates to the field of lighting, and in particular to a portable lighting lighthouse. Background Technology

[0002] In scenarios such as railway maintenance, power and communication facility repair, mining operations, and outdoor emergency rescue, the locations of construction and rescue operations change as the work progresses. Therefore, portable lighting towers are needed to provide temporary illumination. Since these construction sites are often outdoors and cannot be directly connected to the power grid, generators and energy storage tanks are also required. This results in workers carrying excessive equipment, which is inconvenient and physically demanding, hindering the rescue operation. To address these issues, existing portable lighting towers are equipped with power generation and energy storage structures. However, this increases the tower's weight, making it difficult to move by manpower alone.

[0003] Furthermore, the road conditions at construction and emergency rescue sites are complex. Setting up a lighthouse on uneven or sloping surfaces can easily cause it to tip over. To ensure the stability of the lighthouse, ground stakes or connectors need to be driven in, but this limits the lighthouse's mobility, preventing its location from advancing with the construction progress.

[0022] Please see Figure 1 and Figure 2 This utility model provides a portable lighting tower 10, which includes: a lighting component 100, a power distribution box 200, a stand 300, an auxiliary support module 400, and a grounding component 500.

[0023] Please see Figure 1 and Figure 2 The lighting assembly 100 and the bracket 300 are mounted on the distribution box 200. The lighting assembly 100 is used to provide lighting and is equipped with a telescopic lamp post 110 and a lamp head 120 for lighting. The distribution box 200 is a functional accessory that can provide power to the lighting assembly 100 and can also be used as an emergency power source for other electrical appliances at the construction site.

[0024] Please see Figure 1 and Figure 3 The auxiliary support module 400 includes an outer frame 410 and multiple telescopic legs 420. The power distribution box 200 is located inside the outer frame 410. The telescopic legs 420 include a lifting motor 421, a support tube 422 and an inner rod 423. The inner rod 423 is movably disposed inside the support tube 422. The lifting motor 421 is used to drive the inner rod 423 to extend and contact the ground. The number of telescopic support legs 420 can be increased according to the weight of the distribution box 200. In this embodiment, four telescopic support legs 420 are configured, and the telescopic support legs 420 are located on the outer frame 410. The support tube 422 and the inner rod 423 cooperate to form a telescopic structure. After the lifting motor 421 drives the inner rod 423 to extend, the inner rod 423 contacts the ground. The lifting motor 421 then applies force to lift the movable lighting tower 10 off the ground, facilitating its loading onto a vehicle for transfer. Alternatively, the telescopic support legs 420 can be used to support the movable lighting tower 10, maintaining its balance on a slope. Figure 2 As shown.

[0025] Please see Figure 4 and Figure 5Each telescopic outrigger 420 is equipped with a grounding component 500. The grounding component 500 includes a foot pad 510, a switch 520, and a floating block 530. The inner rod 423 is provided with a waist-shaped hole 511 that matches the foot pad 510. The switch 520 is located on the foot pad 510 and is located on the side of the foot pad 510 near the inner rod 423. The switch 520 is used to identify whether the foot pad 510 is in contact with the ground.

[0026] Please see Figure 5 and Figure 6 The inner rod 423 has a groove 11 at its end, and a floating block 530 is movably disposed within the groove 11. A spring 540 is provided between the floating block 530 and the groove wall of the groove 11. The spring 540 is used to push the floating block 530 closer to the switch 520, and there is a gap between the switch 520 and the floating block 530. When the grounding component 500 contacts the ground, the floating block 530 presses the switch 520 to trigger the switch 520. Figure 6 As shown; switch 520 can be a contact switch or a pressure-sensitive switch.

[0027] When the grounding component 500 leaves the ground, push the foot pad 510 away, positioning it away from the end of the inner rod 423 to prevent accidental activation of the switch 520. Figure 5 As shown.

[0028] The principle by which the grounding component 500 enables the portable lighting tower 10 to adapt to complex road surfaces is as follows: When setting up the portable lighting tower 10 or when it needs to be loaded onto a vehicle for transport, the entire tower must be lifted off the ground. For example, when a long-distance transfer is required, the tower is lifted off the ground using the telescopic outriggers 420, allowing the pickup truck bed to be moved under the outriggers 300 to complete the loading operation. Figure 3 As shown, this improves loading efficiency.

[0029] When the telescopic outrigger 420 is in the retracted state, the foot pad 510 is away from the ground, and there is a gap between the foot pad 510 and the end of the inner rod 423, and the switch 520 is in the untriggered state. When it is necessary to set up a movable lighting tower 10 on a slope or rugged road, start the lifting motor 421, and the inner rod 423 begins to extend from the support tube 422. At this time, the foot pad 510 descends. After the foot pad 510 contacts the ground, the gap between the foot pad 510 and the inner rod 423 begins to narrow. The floating block 530 contacts the switch 520, and as the inner rod 423 descends, the floating block 530 begins to compress the spring 540. The pressure on the switch 520 increases until the switch 520 is triggered. The telescopic support leg 420 where the triggered switch 520 is located stops extending, while the other telescopic support legs 420 remain extended until all the switches 520 on all the telescopic support legs 420 are triggered. The first stage of the extension of the telescopic support legs 420 is completed. Next, the lifting motor 421 begins to drive all the inner rods 423 to extend synchronously, thereby raising the movable lighting tower 10 to the target height, and the second stage of the telescopic outriggers 420 unfolding is completed.

[0030] It should be noted that when the fixed location of the movable lighting tower 10 is a rugged road or slope, if all the inner poles 423 are directly driven to extend synchronously, the timing of contact between each foot pad 510 and the ground will be inconsistent. Some foot pads 510 may have already contacted the ground, while others may still be floating. The foot pads 510 that contact the ground first will generate a thrust that causes the tower to tilt. After being raised, the entire tower will be tilted, making it prone to tipping over. This application includes a grounding component 500, which can identify whether each telescopic support leg 420 is in contact with the ground. In the first stage of the extension of the telescopic support legs 420, the telescopic support legs 420 that contact the ground first will stop extending. After all the telescopic support legs 420 have contacted the ground, they will be driven to extend synchronously. This ensures that the tower remains balanced after being raised and will not tilt with the slope, keeping the tower in a stable state and preventing it from tipping over after being extended.

[0031] Please see Figure 5 In one embodiment, the edge of the foot pad 510 is provided with an inclined portion 512, which bends away from the ground. The foot pad 510 is connected to the oblong hole 511 by a bolt, and the foot pad 510 can rotate around the bolt, allowing the foot pad 510 to deflect with the ground.

[0032] Please see Figure 3 In one embodiment, the outer frame 410 has a storage base 430 on its edge that matches the telescopic legs 420. The storage base 430 can accommodate the telescopic legs 420, making the movable lighting tower 10 compact.

[0033] Please see Figure 3In one embodiment, the outer frame 410 is provided with a first connecting rod 411, a second connecting rod 412 and an extension motor 413. The two ends of the second connecting rod 412 are respectively connected to the storage seat 430 and the support tube 422. The first connecting rod 411 is rotatably mounted on the storage seat 430. One end of the first connecting rod 411 is connected to the support tube 422, and the other end of the first connecting rod 411 is connected to the output end of the extension motor 413. The extension motor 413 is used to drive the first connecting rod 411 to swing so that the support tube 422 moves closer to or further away from the storage seat 430.

[0034] In one embodiment, the length of the inner rod 423 is greater than the length of the support tube 422. After the inner rod 423 is retracted, its end protrudes outside the support tube 422, making it convenient to replace the foot pad 510 provided on the inner rod 423.

[0035] Please see Figure 1 and Figure 2 In one embodiment, the movable lighting tower 10 further includes a roller 600, which is located at the bottom of the stand 300. The stand 300 is provided with a mounting groove and a pin 310. The roller 600 is provided with a connecting rod that matches the mounting groove. The side of the connecting rod is provided with a mating hole. The pin 310 cooperates with the mating hole to lock the roller 600, so that a quick-release structure is formed between the roller 600 and the stand 300, which can be quickly replaced when the roller 600 is damaged.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
