Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of photovoltaic of fixed adjustable angle Bracket, including regulating box 1, photovoltaic module 2 and bracket 3.First bearing 4, the right side of regulating box 1 is fixedly mounted in the left end of regulating box 1 Hold inner wall that second bearing 5, the right end of 5 spline connecting worm 6 of second bearing, the left end spline connection first of worm screw 6 is fixedly mounted Runner 7, the lower section engaging worm wheel 8 of worm screw 6 are fixedly connected with after bearing 4.It is worm screw that self-locking condition occurs in Worm Wheel System Expansion helical angle be less than worm and gear contact angle of friction.That is β < Φ, β be worm screw 6 expansion helical angle, Φ be worm screw 6 with Worm gear 8 contacts angle of friction；Tg Φ=μ, μ are coefficient of friction.This reason is not glided with the object on inclined-plane being, is exactly It is required that G*sin α < G*cos α * μ, α are inclined-plane oblique angle, μ is coefficient of friction, and G is gravity.It arranges: tg α < μ, it may be assumed that α < arctan μ When=Φ, the transmission of worm screw 6 has self-locking function, i.e., only worm gear 8 can just rotate in the case where rotary worm 6, from And avoid the external conditions such as wind-force to the angulation change of photovoltaic module 2.Rotation axis 9 is fixedly mounted in the front inner wall of regulating box 1, turns 9 keyway of moving axis connects worm gear 8, and rotation axis 9 is fixedly connected with rotating disc 10 after the rear wall of regulating box 1, and rotating disc 10 is fixed Strut 11 is connected, strut 11 is fixedly connected with the first hinged block 12, and the first hinged block 12 is fixedly connected with the bottom end of photovoltaic module 2.

The top bolt attachment bracket 3 of regulating box 1, bracket 3 are slidably matched sliding sleeve 13, and limit is fixedly mounted in the top of bracket 3 Position block 14, sliding sleeve 13 are fixedly connected with the second hinged block 15, and the second hinged block 15 is fixedly connected with the top of photovoltaic module 2.Regulating box 1 Bottom end be fixedly connected with support column 16, support column 16 is fixedly welded pedestal 17.It is fixedly welded four groups of stiffening plates 18 on pedestal 17, four Group stiffening plate 18 is in triangle block structure, and around the vertical central axis circumferential direction uniform welding of support column 16 in the outer of support column 16 On wall.

Working principle: it as shown in figure 3, by rotating wheel 7, so that needle rotation counterclockwise occurs for worm screw 6, is passed according to worm screw Dynamic principle, worm gear 8 can rotate clockwise, since worm gear 8 and rotating disc 10 are fixedly connected with rotation axis 9, i.e., in coaxial Connection status, so rotating disc 10 can be rotated clockwise with worm gear 8, the strut 11 being fixedly connected with rotating disc 10 is pushed away Deflection counterclockwise occurs for dynamic 2 bottom end of photovoltaic module.Work as photovoltaic due to being limited on bracket 3 with sliding sleeve 13 in the top of photovoltaic module 2 When deflection counterclockwise occurs for 2 bottom end of component, sliding sleeve 13 declines along bracket 3, to change the folder of photovoltaic module 2 Yu horizontal plane Angle, to obtain the sun maximum lighting angle of Various Seasonal.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
