Special mercury solution glass pipe lock of photovoltaic

The utility model provides a special mercury solution glass pipe lock of photovoltaic for electric loop separation is carried out to photovoltaic board terminal box, and mercury solution glass pipe lock is including the mechanical flap of fire prevention, prevent fires mechanical base and mechanical energy storage mechanism, and the laminating of pegging graft of prevent fires mechanical flap and the mechanical base of fire prevention, the inside of the mechanical base of preventing fires be provided with and the prevent fires spring hole of mechanical flap intercommunication, mechanical energy storage establishment of institution is downthehole at the spring, and mechanical energy storage mechanism includes mercury solution glass pipe and spring, and the mechanical flap of mercury solution glass pipe laminating fire prevention is fixed in the spring drill way and is sealed the spring card of compression downthehole at the spring, realize not holding from preventing fires the mechanicalness physics fire prevention mechanism that the inside adoption reliability of photovoltaic board terminal box is the highest to cut off the emergence of electric loop prevention conflagration.
