For convenience of description, the first and second

sub-support beams

In addition, when the photovoltaic cleaning device passes through the twisted bridge, a plurality of walking wheels 7 of the photovoltaic cleaning device are suspended inevitably. When the photovoltaic cleaning device is about to leave the twisted bridge frame, the suspended walking wheels 7 fall and smash the photovoltaic module 15, and the service life of the photovoltaic module 15 is influenced.

sub-support beams

If the axis of the main support beam 1 is parallel to the axis of the road wheels 7, the first and second

sub-support beams

2 and 10 are rotatably disposed on the main support beam 1. In this case, if the cleaning module includes the cleaning shaft 8 and the cleaning implement 9 provided on the cleaning shaft 8, the cleaning shaft 8 is not rotatable.

For the sake of simplicity, the opening of the bearing seat 20 at the end remote from the cleaning element 9 can be blocked by a bearing cap 18.

In the above configuration, the second sub-support beams 10 and the connecting beam 12 are arranged in this order in the axial direction of the cleaning shaft 8, and the second sub-support beam 10 may be selected to be closer to the cleaning implement 9 than the connecting beam 12, or the connecting beam 12 may be selected to be closer to the cleaning implement 9 than the second sub-support beam 10.

The interlocking case 23 is a sealed case capable of storing lubricating oil in order to lubricate the components of the first interlocking mechanism 27 more effectively. Specifically, the lubricating oil is used to lubricate the components of the first linkage 27, and oil immersion lubrication may be used, particularly when the first linkage 27 is a bevel gear transmission.

If the connecting shaft of the first linkage 27 does not extend out of the linkage box 23, the transmission shaft outside the linkage box needs to extend into the linkage box 23. Specifically, the linkage box 23 is provided with a connecting hole, the connecting hole allows a transmission shaft to extend into the linkage box 23 and to be in transmission connection with the first linkage mechanism 27, and the transmission shaft is in sealed connection with the linkage box 23. The transmission shaft is a driving shaft of the walking driving part 3, and/or a shaft in transmission connection with the walking wheel 7, and/or a shaft in transmission connection with the limiting wheel 6.

In practical applications, the two situations can be combined as required. Specifically, as shown in fig. 7, the drive shaft of the travel drive unit 3 extends into the interlocking case 23, and the travel drive unit 3 and the interlocking case 23 are hermetically connected to achieve a hermetic connection of the drive shaft and the interlocking case 23.

Of course, the travel driving member 3 may be disposed at other positions, which is not limited in this embodiment.

In the walking module, the number of the first linkage devices 5 is selected according to actual needs. In a specific embodiment, the limiting wheels 6 and the first linkages 5 can be selected to correspond to each other one by one, that is, the number of the first linkages 5 is the same as that of the limiting wheels 6, so that if there are at least two limiting wheels 6, the volume of the linkage box 23 can be reduced to the maximum extent, thereby facilitating the manufacture, facilitating the installation of each first linkage 5, and improving the installation accuracy.

In another embodiment, there are at least two limiting wheels 6, one first linkage 5, and any two limiting wheels 6 share the same first linkage 5. At this time, all the stopper wheels 6 share the same first linkage 5, so that the number of the first linkages 5 is reduced.

Since the size of the interlocking box body 23 is small, the interlocking box body 23 can be selected to be a material reduction forming box body in order to improve the vertical precision. It will be appreciated that the above-described subtractive forming of the housing is formed by machining. Thus, the mounting accuracy of the first link mechanism 27 is ensured.

In order to facilitate material reduction and forming, the linkage box body 23 is an aluminum box. Of course, the linkage box 23 may be made of other materials, such as stainless steel, which is not limited in this embodiment.

In practical applications, the interlocking box 23 may be manufactured by other methods, such as bending, and is not limited to the above embodiments.

In the walking module of the photovoltaic cleaning device, the walking wheels 7 can be one or more than two. In order to improve the walking stability, the number of the walking wheels 7 can be at least two. In this case, the walking drive components 3 may correspond to the walking wheels 7 one by one, or one walking drive component 3 may be selected to drive at least two walking wheels 7 to walk. The latter may be selected in order to reduce the walking drive members 3.

In an embodiment, in order to reduce the number of the traveling driving parts 3 to the maximum and reduce the cost, the traveling module of the photovoltaic cleaning apparatus further includes a second linkage 28, all the traveling wheels 7 are linked by the second linkage 28, and the second linkage 28 is located outside the linkage box 27. It will be appreciated that one travel drive unit 3 drives all of the road wheels 7 to travel via the second linkage 28. Of all the travelling wheels 7, one travelling wheel 7 is a driving travelling wheel, and the other travelling wheels 7 are driven travelling wheels.

The first linkage mechanism 27 and the second linkage 28 are separately arranged, so that the installation of the first linkage 5 is simplified, the installation of the second linkage 28 is also simplified, the installation of the whole walking module is further simplified, and the installation efficiency is improved; at the same time, it is convenient to ensure the mounting accuracy of the respective components in the second linkage 28.

In the above embodiment, the traveling module of the photovoltaic cleaning apparatus includes the traveling driving unit 3, and the traveling driving unit 3 may select to drive the second linkage 28 to move through the first linkage 27, or the traveling driving unit 3 may select to drive the first linkage 27 to move through the second linkage 28.

Specifically, when the travel driving unit 3 drives the second linkage 28 to move via the first linkage 27, the main body of the optional travel driving unit 3 is fixed to the outside of the linkage case 23, and the driving shaft of the travel driving unit 3 extends into the linkage case 23. If the interlocking case 23 is used for storing lubricating oil, the main body of the travel drive unit 3 and the interlocking case 23 are hermetically connected, or the drive shaft and the interlocking case 23 are hermetically connected.

If the walking driving part 3 drives the first linkage mechanism 27 to move through the second linkage device 28, the walking driving part 3 can be selected to be arranged on the linkage box body 23; alternatively, the travel driving member 3 may not be provided in the interlocking box 23 and the travel driving member 3 may be provided in the frame of the photovoltaic cleaning apparatus.

The specific type of the first linkage 27 is selected according to actual requirements. For the sake of simplicity, the first linkage 27 is a bevel gear transmission. Specifically, as shown in fig. 1 and 2, the first link mechanism 27 includes: a first connecting shaft 22, a first bevel gear 24 provided on the first connecting shaft 22, a second connecting shaft 26, a second bevel gear 25 provided on the second connecting shaft 26 and engaged with the first bevel gear 24; wherein, the first connecting shaft 22 is in transmission connection with the walking wheel 7 and is coaxial, and the second connecting shaft 26 is in transmission connection with the limiting wheel 6 and is coaxial.

It should be noted that the first connecting shaft 22 may or may not extend out of the linkage box 23, and the second connecting shaft 26 may or may not extend out of the linkage box 23. The first connecting shaft 22 and the road wheels 7 can be in direct transmission connection or in indirect transmission connection through other shafts, and the second connecting shaft 26 and the limiting wheel 6 can be in direct transmission connection or in indirect transmission connection through other shafts.

In practical applications, the bevel gear transmission mechanism may be selected as another one, and the first linkage mechanism 27 may be selected as another one, as long as the traveling wheels 7 and the limiting wheels 6 are linked.

The specific structure of the second linkage 28 is selected according to actual needs. For the convenience of transmission, the second linkage 28 may be a chain transmission. Specifically, as shown in fig. 1 and 2, the second linkage 28 includes a sprocket 21 and a chain wound around the sprocket 21. Wherein, the chain wheel 21 is arranged on a transmission shaft in transmission connection with the walking wheels 7, namely, each walking wheel 7 is provided with the chain wheel 21 corresponding to the walking wheel. It will be appreciated that the first drive shaft 22 is provided with a sprocket 21 or that a shaft coaxial with and drivingly connected to the first drive shaft 22 is provided with a sprocket 21.

Above-mentioned sprocket 21 is two at least, and at least one sprocket 21 is drive sprocket, and at least one sprocket 21 is driven sprocket, and drive sprocket and the rotation of the axle of being connected rather than the transmission can drive this epaxial walking wheel rotatory, can drive other sprockets 21 rotations through the chain simultaneously, and the walking wheel that corresponds with other sprockets 21 is rotatory to realize the linkage.

In the above configuration, the driving sprocket 21 is driven to rotate by the traveling drive member 3, and the first link mechanism 27 is driven to move by the traveling drive member 3 via the second link device 28.

In practical application, the chain transmission mechanism can be selected to be of other structures; alternatively, the second linkage 28 may be another mechanism, such as a belt transmission mechanism, which is not limited in this embodiment.

In the above-described walking module, the number of the walking wheels 7 is usually not less than the number of the limit wheels 6. Specifically, the traveling wheels 7 correspond to the limiting wheels 6 one by one, or the number of the traveling wheels 7 is larger than that of the limiting wheels 6. The former may be selected for improved stability.

The first sub-support beam 2 and the second sub-support beam 10 are both sub-support beams. In order to reduce the size of the secondary support beam, the first linkage 5 is located on the side of the secondary support beam away from the cleaning element 9, and the second linkage 28 is located on the side of the secondary support beam close to the cleaning element 9.

Of course, other distribution modes can be selected, and are not limited to the above embodiment.

In practical application, if the gap between two adjacent photovoltaic modules 15 is greater than the center distance between two adjacent walking wheels 7, a bridge frame needs to be built between two adjacent photovoltaic modules 15 to ensure that the photovoltaic cleaning device passes through. However, if the numerical value that the gap between two adjacent photovoltaic modules 15 is larger than the center distance between two adjacent traveling wheels 7 is small, it is not worth building a bridge.

In one embodiment, the center distance between the walking wheels 7 can be adjusted in order to avoid overlapping the bridge and ensure that the photovoltaic cleaning device passes through a larger gap. Specifically, in each walking module, the center distance between any two adjacent walking wheels 7 is used to be greater than the gap between any two adjacent photovoltaic modules 15.

In the above embodiment, this can be achieved by increasing the number of the traveling wheels 7. Specifically, the number of the traveling wheels 7 is at least three. For example, the number of the traveling wheels 7 is four, which is not limited in the present embodiment.

It should be noted that, if the number of the traveling wheels 7 is increased, the length of the secondary support beam needs to be increased appropriately to ensure the installation of the traveling wheels 7. The length of the auxiliary supporting beam is the length of the auxiliary supporting beam in the walking direction. The specific length of the secondary support beam is set according to actual needs, and this embodiment does not limit this.

In order to improve the walking smoothness, the center distance between any two adjacent walking wheels 7 in each walking module can be selected to be not more than 300mm. Of course, the center distance between any two adjacent road wheels 7 can be selected to have other values, and is not limited to the above embodiment.

As shown in fig. 9, the photovoltaic module 15 may be horizontally disposed, and in this case, the walking driving force N = Wf of the photovoltaic cleaning apparatus, where W is the weight of the photovoltaic cleaning apparatus, and f is the friction coefficient between the photovoltaic cleaning apparatus and the photovoltaic module 15. In fig. 9, the arrow line indicates the direction of the pressure applied to the photovoltaic module 15.

As shown in fig. 10, the photovoltaic module 15 may be disposed obliquely. Specifically, the photovoltaic module 15 has an included angle α with the horizontal plane, i.e., the inclination angle of the photovoltaic module 15 is α.

If the walking wheels 7 and the limiting wheels 6 are not arranged in a linkage mode, the walking driving force N = N1= Wfcos alpha of the photovoltaic cleaning device. When the inclination angle alpha of the photovoltaic module 15 is larger than 30 degrees, the pressure of the walking wheel 7 on the photovoltaic module 15 is reduced, and the friction force borne by the walking wheel 7 is reduced, so that the walking driving force is insufficient.

Specifically, as shown in fig. 10, if the traveling wheel 7 and the limiting wheel 6 of the right traveling module are linked by the first linkage device 5, the inclination angle of the photovoltaic module 15 is α, the traveling wheel driving force N1= Wfcos α of the photovoltaic cleaning device, the limiting wheel driving force N2= Wfsin α of the photovoltaic cleaning device, and the traveling driving force N = N1+ N2= Wfcos α + Wfsin α of the photovoltaic cleaning device. In fig. 10, the arrow line indicates the direction of the pressure applied to the photovoltaic module 15.

Known through the above-mentioned contrast, in the above-mentioned structure, when photovoltaic module 15 slope set up, spacing wheel 6 can exert pressure to photovoltaic module 15 to increased whole photovoltaic cleaning device to photovoltaic module 15's pressure, thereby increased walking drive power, made photovoltaic cleaning device can normally work on the great photovoltaic module 15 of inclination.
