The intelligent goods shelf capable of preventing the goods from being overweight comprises a bottom plate and a goods shelf body, the goods shelf body is located above the bottom plate, a pair of rotating plates are arranged between the goods shelf body and the bottom plate, and a sliding groove is formed in the bottom plate. In the actual use process, the goods shelf is connected with the positioning rod and the sliding block through the rotating plate, the sliding block slides in the sliding groove, when the goods shelf bears goods, the weight enables the sliding block to compress the first spring to move downwards, meanwhile, the damping rod and the second spring cooperate for buffering, and the damping rod and the second spring move downwards along with increase of the weight of the goods. By means of the design, the problem that an existing goods shelf cannot automatically monitor overweight is solved, the weight of a traditional goods shelf depends on manual judgment, the goods shelf is prone to deformation and even collapse due to overweight, and the goods shelf is not prone to damage due to the fact that the weight of the goods shelf depends on manual judgment. Through mechanical transmission and pressure triggering, the device can quickly detect the weight and prompt workers.

The utility model relates to a dual-purpose electric tugboat for towing and eliminating, which belongs to the technical field of tugboats and comprises a boat body, a propelling mechanism, a deck house, a consumable liquid tank, a fire-fighting mechanism, a bow battery and a stern battery, and a fore peak, a vacant cabin, a bow battery cabin, a cabin, a stern battery cabin and a steering oar cabin are respectively arranged in the boat body; the propelling mechanism is fixed in the steering oar cabin; the deckhouse is fixed in the middle of a deck of the hull; the consumable liquid tank is arranged in the cabin; the fire-fighting mechanism comprises a fire-fighting pump and a fire-fighting monitor; the fire-fighting pump is fixed in the cabin and is communicated with the seawater tank; and the fire monitor is fixed on the deckhouse and is communicated with the fire pump. According to the utility model, the bow battery and the stern battery are distributed in the bow battery compartment and the stern battery compartment, so that the weight balance of the whole ship is ensured; meanwhile, a fire pump is arranged in a cabin in the middle of the ship body to realize dragging and eliminating dual purposes; in addition, the consumable liquid tank is arranged in the cabin in the middle of the ship body, so that the floating state of the ship body can be prevented from being greatly changed in the liquid consumption process.
