Description

Photovoltaic tracking support

Technical Field

The utility model belongs to the solar photovoltaic power generation field, concretely relates to support is trailed to photovoltaic.

Background

At present, a single-row fixed supporting point of a solar tracking support only has one point at a middle swing arm, two ends of a main shaft have no fixed points, and when the support is in leveling protection, the two ends of the support can swing back and forth ceaselessly under the influence of wind force, so that the main shaft is in a repeated torsion state, and the service life of the main shaft is shortened. Aiming at the problem, the existing support reduces wind vibration by additionally arranging dampers at two ends, but is limited by the working state of the dampers, and the wind vibration cannot be completely eliminated.

Disclosure of Invention

The utility model aims at providing a can eliminate wind when levelling the protect state and shake the influence, the more reliable and more stable photovoltaic of structure trails the support.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

a photovoltaic tracking support comprises an upright post, a main shaft rotatably mounted on the upright post and a braking device used for eliminating wind vibration influence when the photovoltaic tracking support is in a leveling protection state; the braking device comprises a braking swing arm fixedly connected with the main shaft, a braking swing rod with one end rotatably connected with the braking swing arm, a fixed pin shaft fixedly arranged on the stand column and a driver used for driving the braking swing rod to rotate, and a braking clamping groove matched with the fixed pin shaft is formed in the braking swing rod.

Preferably, the driver is a push rod.

Preferably, two ends of the driver are respectively and rotatably connected with the braking swing arm and the braking swing rod.

Preferably, the fixed pin shaft is fixedly arranged on the upright column through two mounting plates fixedly arranged on the upright column, and the fixed pin shaft extends out of the side part of the upright column.

Preferably, a plurality of brake clamping grooves are formed in the brake swing rod.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages: the utility model discloses set up arresting gear on the support is trailed to the photovoltaic, can solve the support and tie the problem of wind vibration under the guard state, make the main shaft have a plurality of fixed points when tie the guard state to eliminate the influence of wind vibration to the support, make supporting structure more reliable and more stable.

Figure 2 is the utility model discloses a photovoltaic tracking support's a part enlargies the schematic diagram.

In the above drawings: 1. a column; 2. a main shaft; 3. a braking device; 4. braking the swing arm; 5. braking the swing rod; 6. fixing a pin shaft; 7. a micro push rod; 8. and a brake clamping groove.

Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

The first embodiment is as follows: the utility model provides a photovoltaic tracking support, includes stand 1, rotates through bearing and bearing frame and installs main shaft 2 in stand 1 upper end, and photovoltaic module installs on main shaft 2 and can rotate along with main shaft 2 through parts such as purlin and sloping that set up on main shaft 2. The photovoltaic tracking support further comprises a braking device 3, and the braking device 3 is used for eliminating the influence of wind vibration on the photovoltaic tracking support when the photovoltaic tracking support is in a leveling protection state.

As shown in fig. 1 and 2, the braking device 3 includes a braking swing arm 4, a braking swing rod 5, a fixed pin 6 and a driver. One end of the braking swing arm 4 is fixedly connected with the main shaft 2 through a hoop, a bolt and the like, and the other end of the braking swing arm extends along a direction approximately parallel to the photovoltaic panel. One end of the brake swing rod 5 is rotatably connected with the brake swing arm 4, for example, a fixing plate is fixedly arranged at the other end of the brake swing arm 4, so that the brake swing rod 5 is connected through a rotating shaft arranged on the fixing plate. The other end of the brake swing rod 5 extends downwards, and a brake clamping groove 8 is formed in the brake swing rod 5. The fixed pin 6 is fixed on the upright 1 and arranged transversely, for example, the fixed pin 6 is fixed on the upright 1 by two mounting plates fixedly mounted on the upright 1, and the fixed pin 6 extends out of the side of the upright 1. The brake clamping groove 8 on the brake swing rod 5 can be matched with the fixed pin shaft 6, so that the fixed pin shaft 6 can be clamped into the brake clamping groove 8. The brake swing rod 5 can be provided with a plurality of brake clamping grooves 8 which are arranged along the axial direction. The driver is used for driving the brake swing rod 5 to rotate. In this embodiment, the driver adopts the micro push rod 7, which can extend and contract, and two ends of the micro push rod 7 are respectively rotatably connected with the middle of the brake swing arm 4 and the middle of the brake swing rod 5, so that the micro push rod 7, the brake swing arm 4 and the brake swing rod 5 form a triangular structure, and when the micro push rod 7 extends and contracts, the triangle deforms.

The operation of the braking device 3 is as follows: when the photovoltaic tracking support is in a normal operation state, the micro push rod 7 is shortened, so that the brake swing rod 5 rotates upwards, and the brake clamping groove 8 is separated from the fixed pin shaft 6. When the photovoltaic tracking support is in a leveling protection state, the micro push rod 7 extends, so that the brake swing rod 5 rotates downwards, the brake clamping groove 8 is clamped on the fixed pin shaft 6, and the brake effect is achieved.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
