Yet, above-mentioned known configurations is by driving elongating or shortening of single telescoping mechanism, to control this swing span swing, and then drive the solar panels rotation to follow sunrise and sunset, but, actual in driving the flexible process of this telescoping mechanism, because the cause that the bulky and weight of sun-following device is quite heavy, if add when driving this bearing revolution simultaneously, can cause this telescoping mechanism to scratch to bend distortion or damage because of the deficiency of rigidity produces, and then the whole operation of influence, and in the process of operation, can produce unsettled phenomenon.

Therefore, how to overcome the various shortcomings of aforementioned prior art, real is the present problem that needs to be resolved hurrily.

The utility model content

In view of this, fundamental purpose of the present utility model provides a kind of drive unit that is used for solar panels solar tracking equipment, by two telescoping mechanisms of driven in synchronism, and integrally-built degree of stability when using to promote.

For achieving the above object, the utility model provides a kind of drive unit that is used for solar panels solar tracking equipment, and this solar tracking equipment comprises bearing, locating rack, swing span and drive unit; Wherein this drive unit comprises: two telescoping mechanisms, gear train and actuators.These two telescoping mechanisms are arranged parallel to each other, and this telescoping mechanism comprises stationary pipes, is located in the lead screw group of this stationary pipes inside, and and the draw-tube that is spirally connected mutually of this lead screw group, this stationary pipes and this locating rack are affixed mutually, and an end of this draw-tube then is connected in this swing span.This gear train comprises connecting pipe that connects these two stationary pipes and the drive link group that is located in this connecting pipe inside, this drive link group and this two mutual transmissions of lead screw group.This actuator is fixed on this gear train, rotates in order to drive this drive link group, and drives synchronously that these two draw-tubes are done to stretch out with respect to these two stationary pipes or the action of retraction.

As can be seen from the above technical solutions, two telescoping mechanisms that the utility model is set up in the drive unit can avoid known technology to drive with single telescoping mechanism in use, and institute causes integrally-built instability and produces the problems such as bending distortion or damage of scratching.Therefore, use the utility model can solve the various shortcoming of known technology, promoted integrally-built degree of stability, have high industrial utilization really.

Embodiment

Further describe viewpoint of the present utility model with following embodiment, but be not to limit category of the present utility model anyways.

See also Fig. 1 to Fig. 4, the utility model is the drive unit 2 that is used for solar panels solar tracking equipment 1, and this solar tracking equipment 1 comprises bearing 11, locating rack 13, swing span 15 and drive unit 2; Wherein this drive unit 2 comprises two telescoping mechanisms 21, gear train 23 and actuator 25.

These two telescoping mechanisms 21 are arranged parallel to each other, and this telescoping mechanism 21 comprises stationary pipes 211, is located in the lead screw group 213 of these stationary pipes 211 inside, and and the draw-tube 215 that is spirally connected mutually of this lead screw group 213, this stationary pipes 211 is affixed mutually with this locating rack 13, one end of this draw-tube 215 then is connected in this swing span 15, wherein, this lead screw group 213 comprises lead screw 2131, one end of this lead screw 2131 is installed with first gear 2133, these draw-tube 215 1 ends are installed with
