Abstract
The utility model provides a unit inter-connection wind electricity blade vortex generator. The vortex generator comprises a bottom plate, vortex fins, a connection pin and the like. The vortex fins are arranged on the bottom plate, the connection pin is arranged on one side of the bottom plate and the other side of the bottom plate is provided with a fixed insertion sleeve. A clamping block A is arranged on the connection pin and a clamping block B is arranged on the fixed insertion sleeve. The connection pin is inserted into the fixed insertion sleeve. Two unit vortex generators are connected in a clamped mode under the interaction between the clamping block A and the clamping block B. The connection pin and the fixed insertion sleeve are added and a clamping structure on the connection pin and the fixed insertion sleeve is used for connecting the two unit vortex generators. The connected vortex generators can directly adhere to blades as long as the sizes of the head and the tail of the vortex generator are determined and the adhering installation difficulty is lowered. Installation straightness and orderliness of the whole vortex generator are ensured, installation precision is improved, and therefore stall regulating is promoted and the power generating efficiency of a unit is improved.
Description
Technical field
The utility model relates to wind power technology field, relates in particular to a kind of cell interconnection type wind electricity blade vortex generator.
Background technique
Wind electricity blade there will be disadvantageous airflow breakaway on the process Leaf surface of rotation, this airflow breakaway can be brought many adverse consequencess, for example increase resistance, reduce lift, cause stall in advance and asymmetric stall etc., the method generally adopting is that vortex generator is vertically arranged on to the premature disengagement that blade surface stops air-flow with a certain established angle, thereby raising generating efficiency, existing vortex generator is set to unit spliced structure, on each unit vortex generator, there is a pair of eddy current fin, when installation, some unit vortex generator need to be bonded in to fan blade surface successively according to the position setting, guarantee that the vortex generator having bondd is straight, each unit vortex generator will be accurately installed, make bonding installation complexity and difficulty large, be easy to make due to installation reason the installation inaccuracy of vortex generator, do not reach the object of stall-adjusted, affect the generating efficiency of unit.
Summary of the invention
According to above technical problem, the utility model provides a kind of easy-to-install cell interconnection type wind electricity blade vortex generator, comprise base plate, eddy current fin, it is characterized in that: also comprise connecting pin, fixing sleeve, clamping block A, clamping block B, described base plate is provided with two symmetrical eddy current fins, one side of described base plate is provided with connecting pin, the opposite side of described base plate is provided with fixing sleeve, on described connecting pin, be provided with clamping block A, on described fixing sleeve, be provided with clamping block B, the connecting pin of a described unit vortex generator inserts the fixing sleeve of another unit vortex generator, interact two unit vortex generators are in clamping connection by clamping block A and clamping block B.
Described clamping block A has N, N >=1.
Described clamping block B has N, N >=1.
Described clamping block A and clamping block B composition clamping structure.
The beneficial effects of the utility model are: the utility model improves on original wind electricity blade vortex generator, connecting pin, fixing sleeve have been increased in the both sides of base plate, two adjacent unit vortex generators are connected with the clamping structure on fixing sleeve by connecting pin, do not need the position before single vortex generator is installed accurately to measure, only need to determine that size just can directly be bonded in the vortex generator connecting on fan blade end to end, reduced the difficulty that bonding is installed; The unit vortex generator of assembly and connection fixed qty according to demand, when being linked together, multiple unit vortex generator still can guarantee that whole vortex generator is straight neat, avoid occurring the situation of wave because alignment error makes vortex generator in artificial bonding process, improve installation precision, thereby promotion stall-adjusted, the generating efficiency of raising unit.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Shown in Fig. 1, the utility model is further described:
As Fig. 1, base plate-1, eddy current fin-2, connecting pin-3, fixing sleeve-4, clamping block A-5, clamping block B-6.
The utility model comprises base plate 1, eddy current fin 2, connecting pin 3, fixing sleeve 4, clamping block A5, clamping block B6, two symmetrical eddy current fins 2 are set on base plate 1, a side at base plate 1 is provided with connecting pin 3, opposite side is provided with fixing sleeve 4, on connecting pin 3, be provided with clamping block A5, on fixing sleeve 4, be provided with clamping block B6, when installation, the connecting pin of a unit vortex generator 3 is inserted in the fixing sleeve 4 of another unit vortex generator, interact two unit vortex generators are in clamping connection by clamping block A5 and clamping block B6.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection domain of the present utility model.
