Description

Path extension rail and its connecting rail between solar panels

technical field

The invention relates to the technical field of track structures, in particular to a path extension track and a connecting track between solar panels.

Background technique

With the rapid development of solar energy technology, in order to improve the utilization rate of solar energy, it is necessary to clean the solar battery panel or the cover panel of the solar battery panel in time to remove the dust on the panel.

In the prior art, solar battery panels are arranged in parallel in a row. In order to save manpower, people set up two parallel rails on the solar panel for placing dust removal and sweeping vehicles to clean the solar panel. When the cleaning vehicle finishes cleaning a row of solar panels, it cannot automatically enter the next row of solar panels for cleaning, and it is necessary to manually move the cleaning vehicle to the next row of solar panels. In the process of dismantling, moving, and installing, it is time-consuming and labor-intensive, and the workload of the staff is heavy, and because the sweeper is heavy, it is easy to cause unnecessary collisions and damage to the sweeper.

For above-mentioned defect, people also propose to arrange track between solar panel, be used for cleaning vehicle to enter next row of solar panel automatically from last solar panel and clean. However, since the strokes of the inner track and the outer track of the track between the solar panels are not equal, and the moving speed of the cleaning vehicle on the inner and outer tracks is equal, when entering the next row of solar panels, the cleaning vehicle will be stuck in the track, resulting in failure. The probability of occurrence is high, which will affect the dust removal of solar panels and reduce the working efficiency of solar panels. And stuck for a long time will also cause damage to the sweeper motor, poor reliability, unable to meet user needs.

Contents of the invention

In order to solve the above problems, the present invention proposes a path extension track and its connecting track between solar panels. At the junction of two rows of solar panels, a connecting track with equilinear travel is set, without changing the original cleaning vehicle and parallel track. Under certain circumstances, the sweeping vehicle can turn around and automatically enter the next solar panel from the previous solar panel, the structure is simple, and the equipment cost is low.

In order to achieve the above object, the concrete technical scheme that the present invention adopts is as follows:

A path extension track, the key of which is: it includes a first track and a second track fixedly connected, and there is a gap between them, and a gap track is movably installed in the gap, and the first track, the gap track, the second track The tracks of the two tracks and the three tracks overlap.

With the above structure, the gap track is movable between the first track and the second track, and the stroke of the whole track is extended by setting the movable length of the gap track. The structure is simple and the path is extended.

Further, the first track and the second track are connected via the gap track, and under the action of external force, the gap track reciprocates between the first track and the second track.

When the cleaning vehicle moves from the first track or the second track to the gap track, according to the direction of the external force, the gap track is driven to move forward or backward along the track extension direction to realize path extension.

To further describe, in order to enable the sweeping vehicle to drive the gap track to move, cogging is provided in the guide rails of the first track, the second track, and the gap track, and cogging is provided on the moving wheel of the cleaning vehicle.

To further describe, in order to limit the extension length of the gap track, a limiting collar is movably sleeved at both ends of the gap track, and a limit block is respectively arranged at both ends of the gap track.

The combination of the limit collar and the limit block can limit the maximum distance that the gap track can move in one direction. The maximum distance of this movement can be set as required.

And the limit collar can prevent the gap track from falling off. Improved reliability of gap tracks.

To further describe, the gap track is supported by rollers.

When the gap track moves, it drives the rollers to rotate, and the rollers support the gap track. In order to support the rollers, the rollers are arranged on the supporting device.

A connecting rail between solar panels composed of path extension rails, including N rows of solar panels arranged in parallel, each row of solar panels is arranged obliquely, and two parallel tracks are arranged in parallel on the solar panels. Cleaning vehicles are arranged on the two parallel tracks, and the parallel tracks between the two solar panels are connected by an arc-shaped connecting track. The connecting track includes an inner track and an outer track, and the stroke of the inner track and the outer track is unanimous.

Through the above design, when the sweeping vehicle moves to the edge of the solar panel, it enters the connecting track, and the inner track and the outer track have the same stroke to reach the next solar panel without changing the cleaning vehicle. The structure is simple, the installation cost is low, and the original structure does not need to be changed.

To further describe, the inner track is composed of at least one path extension track sequentially connected.

Through the above design, the gap track in the path extension track can be set to a corresponding length according to the path difference between the inner track and the outer track. The difference length can be composed of a plurality of path extension tracks, and the multiple path extension tracks are arranged in sequence. On the orbital track until the stroke of the inner track and the outer track are equal. Then the sweeping vehicle can turn without modifying the sweeping vehicle and other equipment during the turning process. And in the process of turning, enter the curved track at the same time, and get out of the curved track at the same time.

To further describe, the inner track and the outer track are used to place the moving wheels on both sides of the cleaning vehicle, and when the moving wheels on the inner side of the cleaning vehicle move onto the gap track, the cleaning vehicle drives the gap track Start to move, and the moving wheel on the outside of the sweeping vehicle makes an arc motion on the outer track. When the inner moving wheels of the sweeping vehicle all move to the gap track, the movement track of the outer moving wheel of the sweeping vehicle on the outer track is arc-shaped, and the inner track path is extended on the gap track.

To further describe, in order to make the gap track reciprocate, the friction coefficient between the moving wheel and the gap track is greater than the friction coefficient between the gap track and the roller arranged at the bottom of the gap track.

Beneficial effects of the present invention: by setting the gap track, the path of the inner track is extended, so that the existing sweeping vehicle can adapt to the turning track, and the turning of the sweeping vehicle can be realized without any modification to the original sweeping vehicle and parallel tracks. The failure probability is low, the structure is simple, and the equipment cost is low.
