Abstract

An anti-falling mechanism, configured and adapted on a photovoltaic panel cleaning equipment for cleaning photovoltaic panels, is provided. The photovoltaic panel cleaning equipment includes a body and a cleaning rack, in which the anti-falling mechanism is being mounted on. The cleaning rack includes several connecting rods which are detachably connected. The anti-falling mechanism includes a first hook and a second hook, each of the first hook and the second hook comprises a fixed part and an anti-falling part, the fixed part is fixedly connected with the anti-falling part and the fixed part is detachably mounted on the first connecting rod. By adopting the anti-falling mechanism, the body of the photovoltaic panel cleaning equipment can be prevented from falling off from the photovoltaic panels during cleaning process of the photovoltaic panels.

Claims

1. A photovoltaic panel cleaning equipment, comprising:

a body, the body comprises an anti-falling mechanism; and

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, wherein the anti-falling mechanism comprising a first hook and a second hook, and each of the first hook comprises a fixed part and an anti-falling part, and each of the second hook comprises a fixed part and an anti-falling part;

wherein the anti-falling mechanism is mounted on the cleaning rack;

the fixed part of the first hook is fixedly-connected with the anti-falling part of the first hook, the fixed part of the second hook is fixedly-connected with the anti-falling part of the second hook, and each of the fixed parts of the first hook and each of the fixed parts of the second hook is detachably mounted on the first connecting rod of the cleaning rack of the photovoltaic panel cleaning equipment, respectively;

wherein the photovoltaic panel cleaning equipment is configured for use on one or more photovoltaic panel arrays, and further comprises an obstacle crossing mechanism, wherein the body further comprises a telescopic mechanism, the telescopic mechanism cooperates with the obstacle crossing mechanism to realize movement of the body from one photovoltaic panel array to another photovoltaic panel array; 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;
