New Description: [New Technology Field] This creation is a kind of stud that can be used for fiber reinforcement. The studs of the roots of wind turbine blades are made to make f# and wind and miscellaneous load-bearing bolts. Locks the rotational power of the blade. Since the _bolt of the device has a thread around it, there is a beveled surface in the middle and rear parts, and there is a pressure difference between the vacuuming of the borrower, and the Brayweb will touch the thread to fully smash the __ cloth. After fully containing the grease hardening, the maximum biting force of the bolts can be added to achieve the goal of applying the device to the root of the wind turbine blade. [Prior Art] The wind turbine blades made of fiber-reinforced plastics and the wind turbine shaft are screw-checked, and the roots of the blades are required to be made into a hybrid structure, which can be reliably carried out. Use buried studs (Stud), and then bribe _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The length is sufficient to transmit light force and the _ cloth can be laid flat. The surface of the stud is roughened. At the back of the stud, the (four) material needs to be provided with a conversion section so that the fiber cloth can be laid flat. Since the (four) material-assisting material is complicated, and there is no keyway to provide the fixing force, the total length of the stud bolt needs to be longer. [New content] For this reason, the purpose of this creation is to propose a pre-embedded stud bolt for the blade root of a wind turbine with a beveled surface and a keyway to facilitate the above work. The creation has a chamfered surface in the rear part of the stud bolt, and the fiber cloth can be laid flat, and the thread is provided outside the stud bolt, and the key surface is provided with a key groove. The key groove can be first placed into the fiber cloth by the pressure of vacuuming. Poor, the fiber cloth will fully engage with the surface of the stud bolt 6 M339584. After the fiber cloth is fully impregnated with the resin, all the surfaces and the keyway can provide the maximum biting force of the embedded stud bolt to achieve the goal of applying the device to the root of the wind turbine blade. [Embodiment] The preferred embodiment of the present invention will be described in detail below with reference to the drawings. Signing the first picture is a plan view of the creation of a pre-embedded stud of a wind turbine blade with a beveled surface and a keyway. The utility model comprises: a stud bolt 10, an outer diameter D, and an outer thread 2〇, which is used for enhancing the interfacial adhesion force between the blade root portion of the fiber reinforced plastic and the stud bolt, and the inner bolt hole 30 of the diameter d is arranged on the center line of the stud bolt to The Ligan joint bolt is used for locking; one end of the stud is thinned into a chamfered surface 4〇, and a keyway 5〇 is provided on the chamfering surface for increasing the fixing force, and the length of the unsloped surface of the column screw is larger than the length of the inner bolt hole . Referring to the second figure, the side view of the creation of a wind turbine blade root pre-embedded stud with a beveled surface and a keyway is shown. The stud is cut by 4 〇, and the final thickness is about 删, and the keyway 5 设有 is provided on the slanting surface of the xiao J. The trailing edge is roughly from the center line of the stud, the depth is downward, and the length of the forward P is h is approximately (1/3 - i/5)d. After the fiber cloth is laid on the root mold 7〇, the thread is placed on the outside of the stud bolt, and the key groove is inserted into the fiber cloth on the beveled surface. By the pressure difference of vacuuming, the fiber cloth will be fully smashed with the stud bolt. At this time, the resin is infused by the vacuum pressure difference to fully impregnate the fiber cloth. After the resin is hardened, the surface and the key groove can provide the maximum biting force of the embedded stud bolt, and the target of applying the device to the root of the wind turbine blade is achieved. The above-mentioned "the wind turbine blade root pre-embedded column bolt with the beveled surface and the keyway" created by the above-mentioned case provides an effective solution to the blade root of the wind-enhanced flap-shaped wind turbine. The problem of fully establishing the bite force of the P-pillar and the interface is already industrially useful, and the new M339584 is notable and progressive, in line with the new patent requirements. However, the above description is only a preferred embodiment of the present invention, and is not limited to a solid surface. That is, the equal changes and materials made by the patent scope are covered by the scope of the creation patent.
