Abstract

The utility model discloses a solar double shaft tracking power station net rack with an auxiliary longitudinal beam structure, belonging to the field of solar power generation, which can overcome the defect that the middle portion of the net rack of the prior solar power station is very easily bended and easily deforms. The solar double shaft tracking power station net rack with an auxiliary longitudinal beam structure is characterized by comprising a transverse beam, wherein the transverse beam is provided with a speed reducer end longitudinal beam and a hinge pin end longitudinal beam, on the speed reducer end longitudinal beam and the hinge pin end longitudinal beam there are provided with transverse supporting beams, and at the middle of the transverse beam there is provided a middle auxiliary longitudinal beam. The solar double shaft tracking power station net rack with an auxiliary longitudinal beam structure can be applied to the solar equipment manufacture industry.

Description

The solar biaxial that has secondary longitudinal beam structure is followed the tracks of the power station rack

Technical field

The utility model belongs to a kind of solar-electricity station equipment, specifically, relates in particular to a kind of solar biaxial that has secondary longitudinal beam structure and follows the tracks of the power station rack.

Background technology

Present large-sized solar double-axis tracking power station, because cell panel is more, load capacity is bigger; Certainly will increase the rack area of support solar cell panel, and the increasing of rack area, must make the spacing of two longerons supporting rack strengthen; The result that girder space strengthens makes propping must increase the thickening increasing again, not so, and the very easily deflection deformation of position, intermediate portion; Lose supporting role, therefore, inquiring into a kind of scheme that solves this problem becomes the task of top priority.

Summary of the invention

The purpose of the utility model provides the solar biaxial that has secondary longitudinal beam structure and follows the tracks of the power station rack, with the rack middle part that solves solar power station support cells plate in the prior art defective of deflection deformation very easily.

The utility model is to adopt following technical scheme to realize: a kind of double-axis tracking power station rack that has secondary longitudinal beam structure; Comprise crossbeam; Crossbeam is provided with reductor end longeron and bearing pin end longeron; Reductor end longeron and bearing pin end longeron are provided with propping, secondary longeron in being provided with in the middle of the said crossbeam.

Preferably be provided with strengthening support between said bearing pin end longeron, middle secondary longeron and the reductor end longeron.

Compared with prior art, the beneficial effect of the utility model is: the utility model is simple and practical, and under the prerequisite of not overstriking propping, rack can bear the cell panel of more multiple amount and can not be out of shape.

Embodiment

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

In Fig. 1, the whole rack of the utility model is supported by crossbeam 5, can connect column below the crossbeam 5.On the crossbeam 5 totally three places be provided with longeron, be respectively bearing pin end longeron 1, reductor end longeron 3 and the middle middle secondary longeron 2 that is provided with that its two ends are provided with, longeron is the skeleton of whole rack, the longeron at this three place plays the effect of support cells plate jointly.Be fixed with some proppings 4 on the vertical direction of three place's longerons, propping 4 is the slender metal pipe of cuboid, and three place's longerons and propping 4 interconnections form a kind of network, and whole network plays the effect of support cells plate.Be provided with strengthening support 6 between bearing pin end longeron 1, middle secondary longeron 2 and the reductor end longeron 3, strengthening support 6 plays fixed network shelf structure and the effect of transmitting turning power.

In Fig. 2; In secondary longeron 2 be divided into up and down two parts; Two parts secure bond forms a fastener hole 7 together in the centre, middle secondary longeron 2 is stuck in the middle of the crossbeam 5 through fastener hole 7, and fixing and locking; Have certain frictional force between fastener hole 7 hole walls and the crossbeam 5, thus crossbeam 5 can drive in secondary longeron 2 make low-speed motion.

In Fig. 3, an end is provided with rotary type bearing 8 on the crossbeam 5, and rotary type bearing 8 connects motor, and can do gyration through driven by motor; Crossbeam 5 is provided with diagonal brace 9, and diagonal brace 9 plays the effect of fastening crossbeam 5, makes it can bear bigger external force effect.

When the utility model moves; By 8 rotations of motor drives rotary type bearing; Through the power of strengthening support 6 transmission and the drive of frictional force; Crossbeam 5 drives reductor end longeron 3, middle secondary longeron 2 and 1 revolution of bearing pin end longeron, and then drives whole rack and do the pitching gyration, and wherein the angle of rack revolution pitching swing is not more than 60 °.In the adding of secondary longeron 2 effectively improved the ability to bear of 4 pairs of cell panel active forces of propping, realized under the prerequisite that does not increase cost and rack weight, effectively increasing the purpose of rack to the external force ability to bear.
