Description

Technical Field

[0001] This utility model relates to the field of power maintenance technology, specifically a warning device for power maintenance. Background Technology

[0002] Electrical maintenance is a high-risk job. Workers face numerous risks during maintenance, such as electric shock, falls from heights, and falling objects. To avoid such incidents, electrical workers have conducted extensive research, such as hanging warning signs like "Working Here," "High Voltage Danger," and "Do Not Close Switch, People Working" at critical points. These measures have played a certain role.

[0003] Existing warning devices are typically placed in a fixed position to provide warnings. However, in practice, they cannot be rotated quickly to provide a warning or have their height adjusted rapidly, thus reducing their effectiveness.

[0004] Therefore, we urgently need to provide a warning device for power maintenance. Utility Model Content

[0005] The purpose of this utility model is to provide a warning device for power maintenance, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a warning device for power maintenance, comprising a base plate and casters, wherein a warning structure is provided above the base plate;

[0007] The warning structure includes a warning mechanism and a support mechanism;

[0008] The warning mechanism includes a forward / reverse motor, a rotating plate, a rotating rod, a limiting plate, and an adjusting box. The output end of the forward / reverse motor is connected to the bottom of the rotating plate. The bottom of the rotating plate is connected to the top of the rotating rod. The bottom of the rotating rod is slidably connected to the inner side of the limiting plate. The top of the rotating rod is connected to the bottom of the adjusting box. An adjusting plate is slidably connected to the inner wall of the adjusting box. A support plate is fixedly installed on the top of the adjusting plate. A warning plate is fixedly installed on the top of the support plate. A reflector is fixedly installed on one side of the warning plate. An alarm is fixedly installed on one side of the warning plate. A bearing plate is fixedly installed on one side of the adjusting box. A fixing bolt is threadedly connected to the inner wall of the bearing plate.

[0009] A further improvement is that the number of rotating rods is six, and the rotating rods are symmetrically distributed at the bottom of the rotating plate. The top of the limiting plate has a rotating groove, and the bottom of the rotating rod is slidably connected to the inner wall of the rotating groove, so that the warning plate can be rotated quickly, thereby enabling better warning work.

[0010] A further improvement is that the number of reflectors is two, which are symmetrically distributed on both sides of the warning board, and the number of alarms is four, which are symmetrically distributed on both sides of the warning board. This allows for a good warning effect even when visibility is poor at night, thus enabling better use.

[0011] A further improvement is that a limiting hole is provided on one side of the support plate, and one end of the fixing bolt is threaded to the inner wall of the limiting hole. The bearing plate is L-shaped, which allows for quick adjustment of the height of the warning plate, thereby enabling better warning work.

[0012] A further improvement is that the support mechanism includes a rotating rod, a movable plate, a connecting plate, a threaded rod, and a second support plate. The top of the rotating rod is connected to the bottom of the movable plate, the top of the movable plate is connected to the bottom of the connecting plate, the inner wall of the connecting plate is threaded to the outer wall of the threaded rod, the bottom of the threaded rod is rotatably connected to the top of the second support plate, and a fixing plate is fixedly installed on the top of the base plate. A second fixing bolt is threadedly connected to the inner wall of the fixing plate.

[0013] A further improvement is that there are four rotating rods, which are symmetrically distributed on the top of the base plate. There are also four support plates, which are symmetrically distributed on both sides of the base plate. An adjustment hole is provided on one side of the movable plate, and one end of the fixing bolt is threaded to the inner wall of the adjustment hole, so that the position and angle of the support plate can be quickly adjusted, thereby better supporting and fixing the device.

[0014] A further improvement is that the bottom of the base plate is connected to the top of the universal wheel, the bottom of the base plate is connected to the top of the forward and reverse motors, and the top of the base plate is rotatably connected to the bottom of the rotating rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This power maintenance warning device enables the rotating of the warning plate through a warning mechanism, allowing warning information to be transmitted from multiple angles and expanding the warning coverage. At the same time, the reflective plates on both sides of the warning plate can reflect light at night, and four alarms can emit warning sounds, forming a dual visual and auditory warning, effectively coping with different lighting conditions and environments, enhancing the warning effect, and enabling rapid adjustment of the warning plate height. It can be adjusted to a suitable height according to the actual needs of the maintenance site, such as the space height and personnel line of sight, to ensure that the warning information is clearly visible and improve the applicability of the device.

[0017] 2. This warning device for power maintenance utilizes a support mechanism to coordinate the rotating rod, movable plate, connecting plate, threaded rod, and support plate two, allowing for flexible adjustment of the position and angle of support plate two. Rotating the threaded rod changes the contact state between support plate two and the ground, while the fixed bolt two adjusts the limit of the movable plate, adapting to different terrains and ensuring the device's stable fixation. The casters at the bottom of the base plate facilitate flexible movement of the device, balancing stability and ease of movement. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6This utility model provides a technical solution: Example 1:

[0027] A warning device for power maintenance includes a base plate 1 and casters 2, with a warning structure provided on the top of the base plate 1;

[0028] The warning structure includes a warning mechanism 3 and a support mechanism 4;

[0029] The warning mechanism 3 includes a forward and reverse motor 301, a rotating plate 302, a rotating rod 303, a limiting plate 304, and an adjusting box 305. The output end of the forward and reverse motor 301 is connected to the bottom of the rotating plate 302. The bottom of the rotating plate 302 is connected to the top of the rotating rod 303. The bottom of the rotating rod 303 is slidably connected to the inner side of the limiting plate 304. The top of the rotating rod 303 is connected to the bottom of the adjusting box 305. An adjusting plate 306 is slidably connected to the inner wall of the adjusting box 305. A support plate 307 is fixedly installed on the top of the adjusting plate 306. A warning plate 308 is fixedly installed on the top of the support plate 307. A reflector 309 is fixedly installed on one side of the warning plate 308. An alarm 310 is fixedly installed on one side of the warning plate 308. A bearing plate 311 is fixedly installed on one side of the adjusting box 305. A fixing bolt 312 is threadedly connected to the inner wall of the bearing plate 311.

[0030] In this embodiment, there are six rotating rods 303, which are symmetrically distributed at the bottom of the rotating plate 302. The top of the limiting plate 304 is provided with a rotating groove, and the bottom of the rotating rods 303 is slidably connected to the inner wall of the rotating groove, so that the warning plate 308 can be rotated quickly, thereby enabling better warning work.

[0031] Furthermore, there are two reflectors 309, which are symmetrically distributed on both sides of the warning board 308, and four sirens 310, which are symmetrically distributed on both sides of the warning board 308. This ensures a good warning effect even when visibility is poor at night, thus enabling better use.

[0032] Furthermore, a limiting hole is provided on one side of the support plate 307, and one end of the fixing bolt 312 is threaded to the inner wall of the limiting hole. The bearing plate 311 is L-shaped, which allows for quick adjustment of the height of the warning plate 308, thereby enabling better warning work.

[0033] When electrical maintenance is required, the operator moves the device to the necessary location for warning purposes. When the warning plate 308 needs to be rotated, the forward / reverse motor 301 (e.g., model 6IK200RGN-CF) is activated, driving the rotating plate 302 to rotate. The rotation of the rotating plate 302 causes the rotating rod 303 to slide inside the limit plate 304, increasing the stability of the rotating plate 302's rotation. The rotation of the rotating plate 302 indirectly drives the warning plate 308 to rotate, enabling the warning plate 308 to provide a rotating warning. Installing a reflector 309 further enhances the warning effect in low-visibility conditions at night. The alarm 310 is activated. For example, the alarm 310, model LTE-1101J, can emit a sound, thereby further improving the warning effect. When it is necessary to adjust the height of the warning plate 308, the fixing bolt 312 is rotated to move it on the inner wall of the support plate 311. The movement of the fixing bolt 312 allows it to be pulled out from one side of the support plate 307, thereby removing the limiting fixation of the support plate 307. At this time, pulling the warning plate 308 moves the support plate 307, and the movement of the support plate 307 causes the adjusting plate 306 to slide on the inner wall of the adjusting box 305, thereby quickly adjusting the height of the warning plate 308, thus improving the warning work and expanding the application range of the warning device. Example 2:

[0034] Based on Embodiment 1, the support mechanism 4 includes a rotating rod 401, a movable plate 402, a connecting plate 403, a threaded rod 404, and a second support plate 405. The top of the rotating rod 401 is connected to the bottom of the movable plate 402, the top of the movable plate 402 is connected to the bottom of the connecting plate 403, the inner wall of the connecting plate 403 is threadedly connected to the outer wall of the threaded rod 404, the bottom of the threaded rod 404 is rotatably connected to the top of the second support plate 405, and a fixing plate 406 is fixedly installed on the top of the base plate 1. A second fixing bolt 407 is threadedly connected to the inner wall of the fixing plate 406.

[0035] In this embodiment, there are four rotating rods 401, which are symmetrically distributed on the top of the base plate 1. There are also four support plates 405, which are symmetrically distributed on both sides of the base plate 1. An adjustment hole is provided on one side of the movable plate 402. One end of the fixing bolt 407 is threaded to the inner wall of the adjustment hole, so that the position and angle of the support plate 405 can be quickly adjusted, thereby better supporting and fixing the device.

[0036] Furthermore, the bottom of the base plate 1 is connected to the top of the caster 2, the bottom of the base plate 1 is connected to the top of the forward and reverse motor 301, and the top of the base plate 1 is rotatably connected to the bottom of the rotating rod 401.

[0037] When electrical maintenance is required, the operator moves the device to the necessary location for warning. Activating the warning mechanism 3 quickly rotates the warning plate 308, and its height can be quickly adjusted for better warning. When the warning device needs to be supported and fixed, rotating the threaded rod 404 moves it along the inner wall of the connecting plate 403. This movement of the threaded rod 404 moves the second support plate 405, allowing it to contact the ground and move the casters 2 away from the ground, thus supporting and fixing the device. To move the device further, the above steps are repeated in reverse to move the second support plate 405 away from the ground. With the caster wheel 2 in contact with the ground, when it is necessary to adjust the angle of the second support plate 405, the second fixing bolt 407 is rotated to move it within the inner wall of the fixing plate 406. The movement of the second fixing bolt 407 allows it to be pulled out from one side of the movable plate 402, thereby removing the limiting fixation of the movable plate 402. At this time, rotating the connecting plate 403 drives the movable plate 402 to rotate, which in turn drives the rotating rod 401 to rotate. The rotation of the connecting plate 403 indirectly drives the second support plate 405 to rotate, thereby quickly adjusting the angle of the second support plate 405. Furthermore, the position of the second support plate 405 can be adjusted according to the actual site conditions to better support and fix the device.
