Detailed Description
The embodiment of the invention provides a solar photovoltaic panel assembly capable of preventing cut injuries, which comprises a support 1 and a photovoltaic panel 2 arranged on the support 1, wherein a mowing assembly is arranged on the support 1, as shown in figures 1-6.

The guide sleeves 5 are arranged on the outer ring of the rotary drum 3 and distributed around the center of the rotary drum at equal angles, the guide sleeves 5 are arranged in an arc shape towards the rotating direction of the rotary drum 3, the blade 7 is in an arc shape with the same radian as the guide sleeves 5, one end of the blade 7 is connected with the guide block 6, the number of the guide sleeves 5 and the number of the blades 7 on each rotary drum 3 are five, and the five guide sleeves 5 are distributed around the center of the rotary drum 3 at equal angles. An outlet 8 for the blade 7 to extend out is formed in the end part of the guide sleeve 5, the supporting piston 9 is vertically matched in the rotary drum 3 in a sliding manner, each guide block 6 is connected with the supporting piston 9 through a connecting rope 10, and the resetting mechanism is connected with the supporting piston 9; the return mechanism can press the support piston 9 in a normal state, and the blade 7 is accommodated in the guide sleeve 5 by the linkage of the connecting rope 10 and the guide block 6.
When mowing, the rotary drum 3 rotates, the blade 7 in the guide sleeve 5 is thrown out of the guide sleeve 5 through centrifugal force generated by rotation, weeds around the support 1 are cut, when mowing is not performed normally, the supporting piston 9 is extruded downwards through thermal expansion of the air bag 12, the supporting piston 9 is linked with the blade 7 at the end part of the guide block 6 through the connecting rope 10 to be retracted into the guide sleeve 5, the blade 7 is not exposed, the space occupied by the guide sleeve 5 is small, and cutting injury of the blade 7 to patrolmen is effectively avoided.
As shown in fig. 5, the supporting plate 11, the air bag 12 and the T-shaped extrusion block 13 are sequentially connected from top to bottom, the supporting plate 11, the air bag 12 and the T-shaped extrusion block 13 are all accommodated in the rotary drum 3, the bottom end of the T-shaped extrusion block 13 corresponds to the supporting piston 9, the air bag 12 is filled with compressed gas which expands with heat and contracts with cold, and the top of the supporting plate 11 is connected with the top of the inner cavity of the rotary drum 3 through a spring 14.
