Technical Field

[0001] This utility model relates to the technical field of warning devices for wind power equipment maintenance, specifically warning devices for wind power equipment maintenance. Background Technology

[0002] During the maintenance of wind power equipment, maintenance personnel need to set up warning devices around the equipment to alert nearby personnel and prevent them from entering the maintenance area. This ensures the safe conduct of the maintenance process and the safety of both maintenance personnel and those in the vicinity.

[0003] When existing warning devices are in use, they fail to alert wind turbines, leaving personnel around the equipment without effective warning and compromising the safety of the maintenance process. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a warning device for wind power equipment maintenance. This device consists of uprights, lifting rods, a reel, reflective strips, hanging holes, a soil-inserting cone, a foot pedal, and hooks. Maintenance personnel insert the soil-inserting cone into the soil by stepping on the foot pedal, thus protecting the wind power equipment with three or four uprights. The reflective strips are then pulled from the reel using the hooks, and adjacent reflective strips are hooked tightly to the hanging holes, effectively surrounding the wind power equipment and providing an effective warning to surrounding personnel. This ensures safety during maintenance and effectively solves the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a warning device for wind power equipment maintenance, including a pole, a lifting rod at the upper end of the pole, a fastening screw at the contact position between the upper end of the pole and the lifting rod, a reel sleeved on the outer side of the lifting rod and the pole, a bearing installed on the inner side of the reel, a reflective strip wound on the reel, a hook at one end of the reflective strip, and a hanging hole near the hook on the reflective strip.

[0006] Furthermore, an audible and visual alarm is installed at the upper end of the lifting rod, and the audible and visual alarm is of the type with a built-in storage battery.

[0007] Furthermore, a foot pedal is fitted onto the lower end of the upright, and a soil-penetrating cone is provided at the lower end of the upright.

[0008] Furthermore, the pedal has a rod hole at its center, and the pedal is inserted into the upright.

[0009] Furthermore, the soil-penetrating cone is connected to the upright via a threaded connection, and the lifting rod is connected to the upright via a fastening screw.

[0010] Furthermore, the hook and the reflective strip are connected by rivets, and the bearing is inserted into the upright and the lifting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of uprights, lifting rods, reels, reflective strips, hanging holes, soil-inserting cones, foot pedals, and hooks, allows maintenance personnel to insert soil-inserting cones into the soil by stepping on the foot pedals, thereby protecting the wind power equipment with three or four uprights. Then, the reflective strips are pulled out from the reels by the hooks, and adjacent reflective strips are hooked tightly to the hanging holes, thus enclosing the wind power equipment with reflective strips, effectively warning surrounding personnel, and ensuring the safety of the maintenance process.

[0017] 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.

[0018] Please see Figure 1-3 This embodiment provides a technical solution: a warning device for wind power equipment maintenance, including a pole 1, a lifting rod 11 at the upper end of the pole 1, a fastening screw 10 at the contact position between the upper end of the pole 1 and the lifting rod 11, a reel 3 sleeved on the outer side of the lifting rod 11 and the pole 1, a bearing 9 installed on the inner side of the reel 3, a reflective strip 4 wound on the reel 3, a hook 6 at one end of the reflective strip 4, and a hanging hole 5 near the hook 6 on the reflective strip 4.

[0019] like Figure 1-3 As shown, during use, three or four devices are placed around the wind turbine. Then, the soil-penetrating cone 2 is inserted into the soil by stepping on the pedal 8. The reflective strip 4 on the reel 3 is pulled out and connected to the reflective strip 4 on the reel 3 of the adjacent lifting rod 11. The hook 6 is hung on the hanging hole 5 on the reflective strip 4, so that the adjacent reflective strips 4 are connected into a whole, thereby maintaining and protecting the wind turbine. The audible and visual alarm 7 can be activated to provide audible and visual alarm reminders during maintenance, preventing surrounding personnel from entering the maintenance area, thereby ensuring the safe conduct of the wind turbine maintenance process.
