This utility model discloses a novel electric gear pump device for electric shovel lubrication truck, relating to the technical field of oil filling trucks for mining equipment. It includes a power compartment, a grease compartment, and a hose reel compartment. The power compartment includes a diesel generator set, a grease lubricating oil tank, a black oil lubricating oil tank, an electric gear pump set, an ultrasonic level gauge, a hose reel, a color paperless recorder, an electrical control cabinet, and a fire extinguisher. A ground-based oil replenishment system is installed on the side of the grease compartment. Ultrasonic level gauges are installed on the three oil tanks within the grease compartment to monitor the oil level in real time. These level signals are transmitted to the color paperless recorder installed on the electrical control cabinet panel. When absorbing oil, if the oil level in the tank is lower than the minimum absorbing level, the paperless recorder will issue a low-level alarm, reminding the operator to stop refueling to prevent the oil pump from running dry and being damaged. When replenishing oil in the tank, the paperless recorder will issue a high-level alarm, prompting the operator to stop oil supply to avoid oil overflow.

The invention belongs to the technical field of pipelines, and particularly relates to an anti-icing heat preservation type water pipe assembly which comprises a water pipe, a valve and a water outlet, the water pipe is made of electronic radiation heat preservation stainless steel, a plug is arranged on a spray head, a sleeve part connected with the spray head is arranged outside the plug, and an abutting part is arranged on the spray head. When a user forgets to open the faucet in advance in cold weather and low temperature when going out, and the temperature reaches below zero, the glass tube is broken due to the material effect, cooling liquid in the glass tube is scattered on the hose and the spray head, and the blocking piece is pushed upwards by the torsion spring at the bottom after being separated from blocking. The blocking pieces rotate at the same time and are attached to one another, the effect of closing and wrapping the plug to seal water flow is achieved, the situation that water flow is sprayed arbitrarily is avoided, meanwhile, after the blocking pieces move upwards, abutting against the baffle is canceled, a first spring between the baffle and the sleeve piece is separated from limitation, and a protruding block is pushed upwards to drive the baffle to move upwards, so that a water outlet is opened; therefore, water flows out of the water outlet.
