[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] See also Figure 1 and Figure 2 The present invention provides a high-power portable work lamp 10 that can be raised or lowered, which includes: a frame 100 and a generator 200 located on the frame 100, a control box 300, a telescopic lamp pole 400, and a lighting module 500.

[0036] See also Figure 1 and Figure 2 A caster 110 is provided at the bottom of the frame 100, a spacer is provided between the control box 300 and the generator 200, and the telescopic lamp pole 400 is rotatably connected to the frame 100; the lighting module 500 includes a bracket 510 and a plurality of lamp heads 520, the lamp heads 520 are rotatably provided on the bracket 510, and the bracket 510 is connected to the telescopic lamp pole 400.

[0037] The generator 200 can use diesel to generate electricity to provide power for the control box 300 and the lamp head 520, so that the work light can provide lighting in places where electricity cannot be connected. The telescopic lamp pole 400, the lighting module 500 and the generator 200 are all electrically connected to the control box 300. Construction workers can control the telescopic lamp pole 400 and the lighting module 500 to start or shut down through the control box 300. When the telescopic lamp pole 400 is extended, the lighting module 500 is hung high to increase the lighting range of the lamp head 520. When it needs to be transported, the telescopic lamp pole 400 can be driven to retract to reduce the overall volume of the work light for easy transportation.

[0038] Among them, casters 110 are set at the bottom of the frame 100 to facilitate the transfer of the liftable high-power portable work light 10 to the target lighting location, which can reduce the transportation pressure; the lamp head 520 is rotatable and the lighting position can be adjusted according to the progress of the on-site construction. There is no need to frequently move the work light, which is conducive to improving the efficiency of emergency construction.

[0039] See also Figure 1 and Figure 2 In one embodiment, a rotating seat 600 is provided at a position on the frame 100 that contacts the telescopic lamp pole 400. The rotating seat 600 includes a rotatably connected fixed block 610 and a first clamp 620. The first clamp 620 is used to clamp the telescopic lamp pole 400. A locking cap 120 is provided on the frame 100. The locking cap 120 is located below the fixed block 610. The locking cap 120 is used to abut against the end of the telescopic lamp pole 400. A second clamp 210 is provided on the outer side of the generator 200. The connection between the locking cap 120 and the telescopic lamp pole 400 is released, and the telescopic lamp pole 400 can be pushed to flip around the fixed block 610 to contact the generator 200. The second clamp 210 is used to fix it to the generator 200, so that the telescopic lamp pole 400 is folded in half, which is conducive to reducing the volume of the work lamp 10, making it convenient to carry, and making it difficult for the telescopic lamp pole 400 to collide with foreign objects during transportation, thereby reducing the probability of damage.

[0040] See also Figure 4 In one embodiment, the lamp head 520 includes a lamp board 521, a front shell 522, a rear shell 523 and a fan 524 located on the rear shell 523, and a plurality of heat dissipation fins are provided on the rear shell 523.

[0041] It should be noted that the number of tools that construction workers can carry and the construction site are limited. Therefore, when carrying out emergency rescue work, only a single lighting device can be installed. Since the lighting range of the lighting device is limited, and the construction workers' positions and construction positions will change with the progress of the rescue and construction, it is necessary to adjust the direction of the lamp head 520 according to the actual construction conditions on site. For example, when the rescue work is just started, the work light is set in the center of the site, and the construction workers construct and set up equipment around the work light. At this time, the work light is required to provide lighting for the front and rear at the same time. Half of the lamp heads 520 on the lighting module 500 are required to face the front, and the other half of the lamp heads 520 are required to face the rear, so as to take into account the lighting needs of the front and rear of the work light; and after the rescue work continues for a period of time, the construction position advances forward, and it is necessary to illuminate the farther front at this time. At this time, all the lamp heads 520 need to be adjusted to the same side for lighting. In order to enable the work light to meet the above requirements, the present application also provides the following embodiments:

[0042] Embodiment 1,

[0043] See also Figure 3 and Figure 4 A reversing joint 700 is provided at the position where the bracket 510 is connected to the telescopic lamp pole 400; an arc-shaped limiting groove 511 and a locking screw 512 are provided at the position where the bracket 510 is connected to the lamp holder 520, and a holding portion is provided on the locking screw 512, and the locking screw 512 can be directly turned by the holding portion.

[0044] The principle of changing the direction of the lamp holder 520 in Embodiment 1 is as follows:

[0045] If the matching state of the lighting module 500 and the telescopic lamp pole 400 is changed to the front, Figure 3 As shown, all lamp heads 520 on the bracket 510 are oriented in the same direction; when the direction of the lamp head 520 needs to be changed, the telescopic lamp pole 400 is first retracted through the control box 300, and the height of the lighting module 500 is lowered, and the screws on the reversing joint 700 are loosened, and the bracket 510 is moved to make it flip 90° around the telescopic lamp pole 400, and then the screws are re-tightened to fix the reversing joint 700 to fix the bracket 510; after completing the above operations, the locking screws 512 are loosened, and the lamp heads 520 on the bracket 510 are moved to make the lamp heads 520 rotate along the arc-shaped limiting grooves 511, and the directions of the lamp heads 520 are adjusted so that the directions of the lamp heads 520 on the upper and lower sides of the bracket 510 are opposite, as shown in FIG. Figure 4 shown.

[0046] By adopting the same adjustment method, the matching state of the lighting module 500 and the telescopic lamp pole 400 can be changed from Figure 4 The displayed state switches back to Figure 3 Status shown.

[0047] It should be noted that, in the above-mentioned process of adjusting the direction of the lamp head 520, it is necessary to operate the telescopic lamp pole 400 to retract, and after the height of the lighting module 500 is lowered, operate the reversing joint 700 to flip the bracket 510, and then rotate the lamp head 520 along the arc-shaped limit groove 511 to change the direction of the lamp head 520. The adjustment process involves multiple steps. The process of extending and retracting the telescopic lamp pole 400 and the process of loading and unloading the lighting module 500 will take up construction time, and require construction personnel who are familiar with the operation of switching the direction of the lamp head 520 to operate, which requires the construction personnel's assembly experience; and after the lamp head 520 is turned in the opposite direction, the fans 524 of the positive and negative groups of lamp heads 520 are arranged relatively, and the interval between the two groups of lamp heads 520 is limited, such as Figure 4 As shown, when the fan 524 is running, the hot air will be blown toward the location of another group of lamp holders 520, resulting in a poor heat dissipation effect.

[0048] Embodiment 2,

[0049] See also Figure 5 and Figure 6 , the difference between Example 2 and Example 1 is that the lighting module 500 further includes an elastic rod 530, a first lever 540, a second lever 550, a push plate 560, a trigger tube 570, a guide rail 580 and a plurality of counterweights 590, the elastic rod 530 is arranged on the lamp holder 520, and a retaining groove 20 matching the elastic rod 530 is opened on the bracket 510, the retaining groove 20 includes two semicircular tracks 21 connected end to end, and a step 22 is provided at the intersection of the two semicircular tracks 21, and the extension line of the intersection of the two semicircular tracks 21 is inclined to the horizontal ground;

[0050] For details, please refer to Fig.11 The depth of the semicircular track 21 decreases from the starting end to the ending end, and the two semicircular tracks 21 are connected end to end, so there is a height difference at the intersection of the two semicircular tracks 21, thereby forming a step 22. When the lamp head 520 rotates, it will drive the elastic rod 530 to move along the stop groove 20. A spring 531 is provided between the elastic rod 530 and the lamp head 520. The spring 531 keeps the elastic rod 530 in contact with the bottom of the stop groove 20. Therefore, when the elastic rod 530 moves from the starting end to the ending end of the semicircular track 21, it will continuously retract, and will re-pop out after the elastic rod 530 enters the other semicircular track 21. Figure 7 As shown, due to the height difference between the intersection of the two semicircular tracks 21, the step 22 prevents the elastic rod 530 from moving in the opposite direction, that is, the elastic rod 530 cannot return to the original path, so that the lamp head 520 can only be flipped in the same direction; further, since the extension line of the intersection of the two semicircular tracks 21 is inclined to the horizontal ground, when the elastic rod 530 abuts against the step 22, the lamp head 520 is in a tilted state.

[0051] The first lever 540 is disposed on the front housing 522 , the second lever 550 is located on the fan 524 , and the first lever 540 and the second lever 550 are located on the same side of the lamp head 520 ;

[0052] See also Figure 8 The push plate 560 is disposed at the end of the telescopic lamp pole 400, the trigger tube 570 is slidably disposed on the telescopic lamp pole 400, the bracket 510 is connected to the trigger tube 570, the trigger tube 570 is used to drive the bracket 510 to rise or fall along the telescopic lamp pole 400, and the push plate 560 is used to push the first lever 540 or the second lever 550 to rotate the lamp head 520, and the rotation angle of the lamp head 520 is greater than 90°;

[0053] The guide rail 580 is disposed in the fan 524, and the counterweight 590 is located at one end of the guide rail 580 facing the ground. Preferably, the counterweight 590 is cylindrical.

[0054] See also Figure 3 , the orientation of each lamp holder 520 on the front bracket 510 is consistent, and the trigger tube 570 is in an extended state, the elastic rod 530 is located in one of the semicircular tracks 21, and the bracket 510 has upper and lower rows of lamp holders 520. The trigger tube 570 cooperates with the push plate 560 to drive the lower row of lamp holders 520 to rotate, so that the orientations of the two rows of lamp holders 520 are the same or opposite, so as to meet different lighting requirements during the rescue operation. The adjustment method is as follows:

[0055] See also Figure 8 and Fig. 9When the trigger tube 570 is retracted, the distance between the bracket 510 and the push plate 560 is reduced, and the push plate 560 contacts the second lever 550. Since the second lever 550 is located on the fan 524, and the center of the second lever 550 is offset from the position where the lamp head 520 and the bracket 510 are connected, the push plate 560 pushes the second lever 550 to rotate the lamp head 520 toward the side where the fan 524 is located. The specific rotation direction is as follows: Figure 8 As shown;

[0056] See also Fig.10 and Fig.11 The lower row of lamp heads 520 continue to rotate until the trigger tube 570 completes the contraction action, and the direction of the lamp head 520 changes from forward to downward. While the lamp head 520 rotates, the elastic rod 530 slides along the stop groove 20 and slides from one semicircular track 21 to the other semicircular track 21. When the lamp head 520 stops rotating, the elastic rod 530 just passes one of the steps 22.

[0057] It should be noted that, since the extension line of the intersection of the two semicircular tracks 21 is inclined to the horizontal ground, that is, the angle of rotation of the lamp head 520 in the above process is greater than 90°, at this time the lamp head 520 is in an inclined state, and the guide rail 580 is also in an inclined state, then the counterweight 590 rolls along the inclined direction of the guide rail 580, moving from one end of the guide rail 580 to the other end, so that the center of gravity of the lamp head 520 is shifted in the inclined direction;

[0058] See also Fig.12 and Fig.13 Therefore, after the trigger tube 570 is extended again, the tilted lamp head 520 will continue to rotate in its tilted direction under the action of the counterweight 590 until the guide rail 580 becomes vertical. At this time, the lamp head 520 has just completed a 180° flip, and the lighting direction of the lamp head 520 has changed.

[0059] The first lever 540 is located above the push plate 560. When the trigger tube 570 retracts again, the push plate 560 will contact the first lever 540, causing the lamp head 520 to rotate in the same direction again and flip 180° in the same way to restore the direction of the lamp head 520.

[0060] It can be seen that the push plate 560 cooperates with the first lever 540 and the second lever 550 to make the lamp head 520 rotate initially, so that the lamp head 520 is in a tilted state, so as to drive the counterweight 590 to move along the guide rail 580, change the center of gravity of the lamp head 520, and then make the lamp head 520 rotate further, thereby changing the direction of the lamp head 520. In this process, the elastic rod 530 cooperates with the step 22 to limit the rotation direction of the lamp head 520, so that the lamp head 520 can only rotate in the same direction.

[0061] It should be emphasized that the process of changing the lighting direction of the lamp head 520 does not require the retracting of the telescopic lamp pole 400, nor does it require the disassembly of the lighting module 500. Construction personnel can remotely control the lamp head 520 on the ground to change the lighting direction. Compared with the reversing method of Example 1, the reversing method of Example 2 is more efficient, which is beneficial to improving the reversing efficiency of the lamp head 520. At the same time, in the process of changing the direction of the lamp head 520, there is no need to adjust the bracket 510. The bracket 510 always remains in a vertical state. The lamp head 520 only changes its angle. The fan 524 on the lamp head 520 will not be "face to face" due to the change in direction, and the heat dissipation effect is guaranteed.

[0062] Furthermore, the process of changing the lighting direction of the lamp head 520 is triggered by the telescopic action of the trigger tube 570, and the trigger tube 570 itself is built into the telescopic lamp pole 400, and is the part on the telescopic lamp pole 400 that is connected to the bracket 510. The telescopic action of the trigger tube 570 is used to drive the lamp head 520 to change direction, and no additional motors, electric motors and other electronic control accessories are added to the lamp head 520, so that the lighting module 500 can remain light.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
