A bearing sleeve pipe is sleeved on the center of the transverse shaft and is fixedly connected with the top of the support column. A supporting stand extends from the center of the support column. The upper end of a sleeve pipe is hinged on the supporting stand. The upper end of a leading screw is hinged in the center of one side of the support, and the other end of the leading screw passes through the sleeve pipe to extend downwards. A motor is fixedly connected on the lower end of the sleeve pipe. The output shaft of the motor is provided with a worm arranged in a coaxial manner. The worm is engaged with a worm gear having internal screw threads. The internal screw threads of the worm gear are engaged with the leading screw. According to the utility model, transmission of the worm gear and the worm and transmission of a screw and the leading screw are utilized, thereby solving a problem that a cell panel support is difficult to be adjusted during use and improving the capability of a photovoltaic array for absorption of solar radiation energy.

Description

The solar-cell panel support tumbler

Technical field

The utility model relates to a kind of solar-cell panel support, relates in particular to a kind of solar-cell panel support tumbler.

Background technology

Along with the appearance of energy shortage phenomenon, solar power system more and more causes people's attention.For the conversion efficiency of the photovoltaic generating system that improves solar panel, need to improve the ability that photovoltaic array absorbs solar radiation energy.Existing solar-cell panel support all is to be fixedly mounted on the clump or tiling is fixed on roof etc. sunlit place is arranged, and usually in case install and fix, the direction of cell panel is difficult to adjustment, must move through manual work, wastes time and energy.Since solar incident angle round the clock, seasonal variations, hard-wired photovoltaic array can not fully absorb the energy of solar radiation, is unfavorable for improving photoelectric conversion rate.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, a kind of solar-cell panel support tumbler is provided; This device can be adjusted the direction of panel array at any time according to the running orbit of the sun; To reduce incidence angle; Under identical radiation parameter, the more solar radiation energy of absorptance fixed installation photovoltaic array.

The solar-cell panel support tumbler that the utility model proposes; Comprise bracket upright post and be used for the support that cell panel is installed; Comprise that also two ends are fixed on the transverse axis on the described support, a bearing sleeve is overlapped at the middle part of this transverse axis, and this bearing sleeve is fixedly connected with said bracket upright post top.A bearing is stretched out at said bracket upright post middle part; The upper end of one sleeve is articulated on the bearing; The other end that the upper end of one leading screw is articulated in support one middle side part, leading screw passes said sleeve and stretches out downwards, and the lower end of said sleeve is fixedly connected a motor, coaxial on this motor output shaft a worm screw is set; This worm screw and one has the worm gear engagement of internal thread, and the internal thread of worm gear and the engagement of said screw mandrel.

Wherein, also comprise a control motor positive and inverse and the control circuit of accurately locating.

Described bearing sleeve can be connected with the top of described bracket upright post through a holder.

Compared with prior art, the utility model has the advantages that:

1, the rising of leading screw, descending to being rotated by tapped worm gear drives, and by the rising of leading screw with descend and realize, leading screw is if rotate then and can't not rise, descend around the rotation of transverse axis for support, thereby has self-locking performance.Leading screw can only transmission bracket, and support can not turn-screw, can not rotate automatically to guarantee sun support this solar battery apparatus under the situation of large wind.

2, the lead screw transmission ratio is big, the worm drive compact conformation, and bearing capacity is big, and volume is little, in light weight

Stable working, impact, vibrations, noise are little.

3, this device is simple to operate, and price is low, dependable performance, and tracking accuracy is high, can be implemented under the various weather to follow the tracks of.

4, improved the ability of the photovoltaic array absorption solar radiation energy of solar cell, exceeded 30% than other hard-wired generated power of solar cell.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

To shown in Figure 3, the solar-cell panel support tumbler that the utility model discloses comprises bracket upright post 1 and is used for the support 2 that cell panel is installed like Fig. 1.Comprise that also two ends are fixed on the transverse axis 3 on the support 1, the middle part of this transverse axis is with a bearing sleeve 4, and this bearing sleeve is fixedly connected with bracket upright post 1 top through a holder 12.The upper end that a bearing 5, one sleeves 11 are stretched out at bracket upright post 1 middle part is articulated in bearing 5), the other end that the upper end of a leading screw 6 is articulated in middle side part on the support 2, leading screw 6 passes sleeve 11 and stretches out downwards.The lower end of sleeve 11 is fixedly connected a motor 7, coaxial on this motor output shaft a worm screw 8 is set, and this worm screw and has worm gear 9 engagements of internal thread, and the internal thread of worm gear 9 meshes with screw mandrel 6.The utility model also comprises a control motor positive and inverse and the control circuit of accurately locating.

The utility model is to realize like this rotating, and is as shown in Figure 2, and motor 7 rotates, and drive worm gear 9 through worm screw 8 and rotate, and the internal thread of worm gear 9 (being equivalent to hold-down nut) and screw mandrel 6 engagements rotated, moved up and down while drive screw mandrel 6.Hinged through with support 2 upsides drives the rotational of the support 2 of cell panel around transverse axis 3 is installed.Control through control circuit can reality along with the running orbit of the sun is adjusted the direction of support 2 panel arrays, increasing incidence angle, thereby make cell panel can obtain more solar radiation energy.

Thereby the rising of the utility model through the electric-motor drive leading screw, the rotation that drives support of descending realize following the tracks of.The rotating of motor can realize through control circuit, when the position of arrivals needs, also can realize accurate in locating through the braking to motor.Solved the problem that battery board bracket in using is difficult to adjust direction, improved the ability that photovoltaic array absorbs solar radiation energy, the utility model exceeds 30% than other fixing installation energy output. In addition, worm gear 9 is driving links, and leading screw 6 is Passive parts, and leading screw can not rotate automatically then and can't rise, descend, thereby has self-locking performance.Can guarantee that promptly leading screw can only swinging mounting, and support can not turn-screw, can not rotate automatically to guarantee sun support this solar battery apparatus under the situation of large wind, can be to guarantee battery board bracket because of external force rotation automatically.

Battery board bracket was difficult to adjust the problem of direction during the utility model had solved and used, and had improved photovoltaic

Array absorbs the ability of solar radiation energy, exceeds 30% than other hard-wired generated power of solar cell.In addition, because the leading screw tooth is the continuous uninterrupted helical tooth, be continuously during the engagement of it and worm gear, the internal thread tooth does not get into and withdraws from the process of engagement, and therefore, stable drive, noise are very little.
