1. A photovoltaic panel cleaning equipment adapted for use on photovoltaic panel arrays, the photovoltaic panel cleaning equipment comprising:

  • a body, the body comprising;

    a cleaning mechanism, comprising;

    a cleaning rack comprising a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod which are detachably connected;

    a cleaning member, the cleaning member being detachably mounted between the first connecting rod and the third connecting rod and used for stripping off adhesive materials on at least one of the photovoltaic panel arrays;

    a sweeping member, the sweeping member being detachably mounted on the second connecting rod and the fourth connecting rod and used for sweeping the adhesive materials away from at least one of the photovoltaic panel arrays; and

    a cleaning member power unit, the cleaning member power unit is connected to the cleaning member and is used for driving the cleaning member to rotate, wherein the cleaning member power unit comprises a self-locking device, and the self-locking device is used for preventing the cleaning member from idlings;

    wherein the photovoltaic panel cleaning equipment further comprises an obstacle crossing mechanism;

    the body further comprises a telescopic mechanism and the telescopic mechanism cooperates with the obstacle crossing mechanism to facilitate moving the body from one photovoltaic panel array of said photovoltaic panel arrays to another photovoltaic panel array of said photovoltaic panel arrays; and

    the obstacle crossing mechanism comprises a moving rack and a fixed rack, a locking device is arranged on the fixed rack, a limiting member is arranged on the moving rack and the locking device cooperates with the limiting member to lock the moving rack on the fixed rack;

    the locking device comprises a bottom plate, a locking hook, a rotary force applying member, a restoring member, a first stand column, a second stand column, a third stand column, a fourth stand column and a pulling rope;

    the bottom plate is fixed on the fixed rack;

    a fixed column is arranged on the bottom plate and the locking hook is rotatably connected with the fixed column;

    the rotary force applying member is connected with one end of the locking hook and an external force enables the rotary force applying member to move the locking hook from a locked position to an unlocked position to unlock the limiting member;

    the restoring member is arranged at a junction between the rotary force applying member and the locking hook, and when the external force acting on the rotary force applying member disappears, the restoring member enables the locking hook to be restored to the locked position;

    the first stand column and the fourth stand column are located at two ends of the bottom plate, and the second stand column and the third stand column are located between the first stand column and the fourth stand column;

    two vertical pulleys which are respectively at an upper position and a lower position are arranged on each of the first stand column and the fourth stand column;

    a horizontal pulley is arranged on each of the second stand column and the third stand column; and

    the pulling rope is wound on the vertical pulleys and the horizontal pulleys and then is connected with the rotary force applying member.
