Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a wind power blade tip warning protection device. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free renewable energy source that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. People are interested in how to use wind to generate electricity. Using wind power to generate electricity is very environmentally friendly, and the wind energy reserves are huge, so it is increasingly valued by countries around the world. Wind turbine blades are the core components of wind turbines that convert natural wind energy into electrical energy for wind turbines, and are also the main basis for measuring the design and technical level of wind turbines. Generally speaking, starting from the 0m section of the blade, according to the length of the blade, the area within 95%-100% is the tip of the wind turbine blade.

[0003] When transporting wind turbine blades at sea, they are directly fixed on the transport deck through a frame. Due to the strong winds and waves at sea, the wind turbine blades are easily contaminated by seawater during transportation, causing corrosion to the wind turbine blades.

[0004] To this end, we propose a wind turbine blade tip warning protection device to solve the above problems. Utility Model Content

A motor is fixedly connected in the cavity, and the driving shaft of the motor is coaxially and fixedly connected to one of the winding rollers. Two transmission grooves are provided between the cavity and the storage cavity, and the transmission grooves penetrate the bottom plate, the vertical plate and the horizontal plate respectively. A sliding rod is slidably connected in the transmission groove, and the sliding rod and the winding roller on the same side are fixedly connected by two traction ropes, and a protective cloth is fixedly connected between the sliding rod and the reset roller on the same side.

[0008] Furthermore, the gear set includes two gears meshing with each other, and the two gears are coaxially fixedly connected to two reset rollers respectively.

[0009] Furthermore, the two reset rollers are rotationally connected to the storage chamber via a spiral spring, and the installation directions of the two spiral springs are opposite.

[0012] Furthermore, two adjacent bottom plates are connected by buckles, and two adjacent horizontal plates are connected by buckles.

[0013] Compared with the prior art, the beneficial effects of the present invention are at least:

[0014] By setting a reset roller and a winding roller, when the wind sensor detects that the wind force on the sea surface is strong, the two winding rollers are driven to rotate by a motor, and the winding rollers wind up the traction rope. The traction rope pulls the protective cloth through the sliding rod, thereby unfolding the protective cloth until the protective cloth contacts the baffle. At this time, the wind turbine blades placed on the bottom plate can be fully protected to avoid contact with seawater and surface corrosion. When the wind turbine blades are transported, the protection effect is better.

[0015] The utility model can comprehensively protect the wind turbine blades, avoid the wind turbine blades from contacting with seawater and causing corrosion, and has a good protective effect on the wind turbine blades. BRIEF DESCRIPTION OF THE DRAWINGS
