Abstract
The utility model relates to a small size wind electric power generator, comprising a supporting frame, blades, a generator and a control circuit. The supporting frame is a tower type frame composed of a plurality of three-legged supporting frames via stacking and connection, and every section of three-legged supporting frames are composed of three vertical angle iron and cross supports vertically connected with the vertical angle iron. The cross supports form an equilateral triangle shape, the bottoms of the tower type frames are fixedly connected with three positioning spuds on a chassis, and the top parts of the tower type frames are fixedly connected with the upright posts of a generator stand. The supporting frame having stable structure, high strength and convenient installation can not shake when meeting heavy wind, and the small size wind electric power generator can be utilized safely.
Description
The utility model relates to a kind of device that utilizes wind energy power, particularly a kind of small-sized wind power generator.
The claimant discloses a kind of wind-driven generator (patent No. 86210124.7) in the patent of first to file, be made up of supporting frame, fan blade, speed governing wind wheel, generator and charge-discharge control circuit, inversion ac power supply.Through practical application in a few years, find that it still exists some shortcoming and defect parts, at first, former supporting frame is whole tubular type frame, meets strong wind and can rock, shake, lack Security, and height can not be regulated, installation and maintenance are all inconvenient, secondly, the fan blade made from glass fibre reinforced plastics is hollow shape, and the sealing two ends time has been grown and can be out of shape, ftracture, make water inlet in the blade, the influence starting causes fan blade galloping, also has, originally there was not braking mechanism, meet high wind and can only remove to catch on the fan blade of rotation with the pole of buckle, operation easier is big, can not in time brake.
The purpose of this utility model is that the supporting structure of improvement wind-driven generator provides a kind of small-sized wind power generator with intensity height, easy-to-install supporting frame.
The further purpose of the utility model is, a kind of small-sized wind power generator of the braking mechanism of fan blade and easy operating stably of not intaking, turn round that has is provided.
The utility model technical solution is: the supporting frame of small-sized wind power generator is stacked tower of connecting to form of some three-legged supports, every joint three-legged support is formed by three vertical angle bar with the stull connected vertically of vertical angle bar, stull is equilateral triangle, fixedlying connected with the dowel pile on the chassis in tower bottom, fixedlys connected with the generator pit vertical rod in the top.
The further technical solution of the utility model is as follows: the inner foam-filled plastics of (1) fan blade, outer wall is a sealed glass steel layer, (2) braking mechanism is made up of spring, hinge, brake lever and brake stay cord, spring one end is fixed on the support rear side, the other end is connected with the brake lever front end, and hinge is contained in the support front side, and it rotates page or leaf fixedlys connected with the brake lever middle part, braking rope one end connects the brake lever tail end, and the retaining ring that the other end passes on the support afterbody hangs from above.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model small-sized wind power generator overall structure schematic representation.
Fig. 2 is a support frame structure schematic representation of the present utility model.
Fig. 3 is the plan view of Fig. 1.
Fig. 4 is a blade structure cut-away view of the present utility model.
Fig. 5 is a braking mechanism schematic representation of the present utility model.
Fig. 6 removes plan view behind fan blade, generator and the tail vane for Fig. 4.
As shown in Figure 1, the composition of the utility model small-sized wind power generator comprises supporting frame 25, fan blade 15, speed governing wind wheel 13, tail vane 23, generator 14.
As shown in Figures 2 and 3, the supporting frame of small-sized wind power generator is some joint three-legged support 7 stacked tower of connecting to form, every joint three-legged support is formed by three vertical angle bar 5 with the stull 4 connected vertically of vertical angle bar, stull is equilateral triangle, tower bottom three-legged support fixedlyed connected with three dowel piles 8 on the chassis 9, and the top three-legged support is fixedlyed connected with generator pit vertical rod 1.2,3 are the fixing upper and lower external member of vertical rod among the figure, and 6 is fixedly connected adjacent three-legged support and fixedly connected the screw of bottom bracket and dowel pile, and 10 is the ground nail hole on the chassis.This support frame structure is stablized, and the intensity height is worked under rated wind speed and need do not moved, and the chance strong wind does not rock, and guarantees that small-sized wind power generator is safe and reliable, and Height Adjustable, installs, dismantles, keeps in repair, transports all very convenient.
As shown in Figure 4, the inner foam-filled plastics 11 of fan blade, outer wall is a sealed glass steel layer 12.Fill out foamed plastics in the fan blade, be convenient to the frp layer integral sealing, internal layer can not intake year in and year out, has guaranteed the static balancing and the dynamic balancing of wind wheel, has improved the complete machine performance, has prolonged working life.
As shown in Figure 5 and Figure 6, the braking mechanism of small-sized wind power generator is made up of spring 18, hinge 24, brake lever 17 and brake stay cord 20, spring 18 1 ends are fixed on support 16 rear sides, the other end is connected with brake lever 17 front ends, hinge 24 is contained in support 16 front sides, it rotates page or leaf fixedlys connected with brake lever 17 middle parts, and braking rope 20 1 ends connect the brake lever tail end, and the retaining ring 21 that the other end passes on the support afterbody hangs from above.15 is fan blade among the figure, and 13 are the speed governing wind wheel, and 14 is generator, and 1 is the support vertical rod, and 23 is the support tail vane, and 22 for turning to stay cord, and 19 for turning to the stay cord pull bar.When needing brake, earlier by turning to stay cord 22 that wind wheel is turned, avoid wind, strain brake stay cord 20 then, brake lever 17 is that fulcrum turns an angle with hinge 24, and front end stretches out, and stops fan blade 15, and it is stopped the rotation, and reaches the brake purpose.Behind the releasing of brake stay cord, under the effect of spring 18, brake lever 17 restores to the original state again.This braking mechanism is simple, practical, and is easy to operate, easy to installation and maintenance at ordinary times, can brake rapidly during strong wind, avoids complete machine to be scratched.
