The invention discloses a cab-free pure electric wide-body dumper which comprises a circuit overheating protection unit arranged on a dumper body and used for controlling on-off work of equipment; the circuit overheating protection unit comprises a dustproof secondary port adjusting assembly, a deblocking overheating self-locking assembly arranged in the dustproof secondary port adjusting assembly, and a circuit wiring assembly connected with the dustproof secondary port adjusting assembly. The device has the beneficial effects that the structure is compact, and the occupied space is small; the junction box is sealed and dustproof during storage, is quickly powered on and opens a heat dissipation opening during use, can be powered off for cooling according to the heating condition of the junction box and is adaptively enlarged in heat dissipation space when being powered on, and can be automatically locked only by powering off after an overheating condition occurs, so that re-energization caused by mistaken touch is avoided; when remote control is needed, only one set of remote control electric cylinders needs to be added, the effect can be achieved by controlling stretching and retracting of the electric cylinders, a complex redundant device is not needed, and the electric unloading device is suitable for the compact space of electric unloading.

    本发明公开了一种无驾驶室纯电动宽体自卸车,包括线路过热保护单元,设置于车体上,用于控制设备的开关工作;线路过热保护单元包括防尘二次调口组件、设置于防尘二次调口组件内部的解封过热自锁组件,以及与防尘二次调口组件连接的线路接线组件。本发明的有益效果为结构紧凑,占用空间小;在存放时密封防尘,在使用时快速通电并开启散热口,可根据接线盒处的发热状况断电降温并且在接通时适应调大散热空间,在出现过热状况后只要断电便可自动锁定,避免误触再次通电;在需要远程控制时只需添加一组远程控制的电缸,通过控制电缸的伸缩便可实现上述效果,无需复杂的冗余装置,适用于电动卸车的紧凑空间。
