Description

Technical Field

[0001] The utility model relates to the field of photovoltaic cleaning robots, in particular to a photovoltaic cleaning robot with a suspension device. Background Art

[0002] In today's society, energy issues are becoming increasingly prominent. As a clean and renewable energy source, solar energy has been widely used. Photovoltaic power generation systems convert solar energy into electrical energy through photovoltaic modules. However, when photovoltaic modules are exposed to outdoor environments for a long time, they will be affected by pollutants such as dust, dirt, and bird droppings, thereby reducing their power generation efficiency. Therefore, they need to be cleaned in time. Traditional methods are generally manual cleaning and water truck cleaning. Manual cleaning is labor-intensive, inefficient, and has certain safety risks; water truck cleaning requires a lot of water resources and may cause damage to photovoltaic modules. In order to solve these problems, photovoltaic cleaning robots came into being, but traditional photovoltaic cleaning robots still have certain limitations when used.

The technical solution of the utility model effectively solves the technical problem of the crawler slipping and deflecting on the photovoltaic panel in the prior art; the photovoltaic cleaning robot of the utility model has good anti-skid effect, high safety performance and high cleaning efficiency.

[0004] Although the device has certain improvements and can provide support for the middle part of the track to avoid problems such as slipping and deviation, the device still has the following shortcomings.

Moreover, the device only provides support for the track, and the buffering effect is poor. When encountering bumps, the device will still shake, which affects the stability of the device to a certain extent. Therefore, a photovoltaic cleaning robot with a suspension device is proposed to solve the above problems. Utility Model Content

The connecting rod 53 and the positioning wheel 54 are concentric, and the positioning block 51 is inserted into the inner wall of the positioning groove 501.

The cleaning roller 82 is clamped on the front surface of the stopper 84, and the stopper 84 can be limited. The rear surface of the stopper 84 is set to an inclined surface. The inclined surface of the stopper 84 is squeezed, and the stopper 84 will move upward. The stopper 84 passes through and is slidably connected to the lower surface of the cleaning plate 6. One end of the limit spring 83 is fixedly connected to the upper surface of the stopper 84, and the other end of the limit spring 83 is fixedly connected to the inner wall at the top of the cleaning plate 6. When the stopper 84 moves upward, it will squeeze the limit spring 83 to generate a reaction force.

[0036] Working principle: When using this device, first place the device directly on the photovoltaic panel, then start the robot body 1 to drive the guide wheel 3 to rotate and then drive the crawler 4 to drive, so that the device can move, and start the motor 7 to drive the rotating shaft 81 and the cleaning roller 82 to rotate. The rotating cleaning roller 82 can clean the surface of the photovoltaic panel.

[0037] When encountering bumps, the contact point between the track 4 and the bump will bulge upward, thereby driving the positioning wheel 54 to move upward, and the positioning wheel 54 will drive the mounting block 55 to move synchronously, and the mounting block 55 will retract into the positioning plate 52 to squeeze the compression spring 56 to generate a reaction force, and the mounting block 55 will also squeeze the inclined surface of the slider 57, driving the slider 57 to move laterally, and the laterally moving slider 57 will squeeze the connecting spring 58 to generate a reaction force. Through the cooperation of the above-mentioned devices, the force in a single direction can be transmitted to three directions, which has the effect of force distribution, and the reaction force of the connecting spring 58 and the compression spring 56 can play a buffering role, which can ensure the smooth movement of the device.

[0038] When the device is in normal use, the reaction force of the compression spring 56 and the connecting spring 58 will push out the mounting block 55, thereby pushing out the connecting rod 53 and the positioning wheel 54 and fitting them to the track 4, providing support for the track 4, maintaining tension, and reducing the risk of the track 4 falling off.

[0039] When the cleaning roller 82 needs to be replaced, the block 84 is moved upward to release the obstruction to the cleaning roller 82, and then the cleaning roller 82 is removed and the new cleaning roller 82 is taken out, and the slot 801 is aligned with the rotating shaft 81 and then plugged in. During the plugging process, the cleaning roller 82 will squeeze the inclined surface of the block 84, and the block 84 will move upward to release the obstruction and squeeze the limit spring 83 to generate a reaction force. When the cleaning roller 82 is installed, the squeezing of the block 84 will be released, and the reaction force of the limit spring 83 will push the block 84 to move downward to block the right surface of the cleaning roller 82.
