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.

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.

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.

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.
