The invention discloses an environment-friendly power distribution cabinet for a sponge city. The power distribution cabinet comprises a cylindrical power distribution box body and is characterized inthat a plurality of cooling fans are fixed at the inner bottom of the power distribution box body, an annular water storage cavity is formed on a side wall of the power distribution box body, a plurality of drainage pipes communicating with the interior of the water storage cavity are inserted into an outer wall of the power distribution box body in a penetrating mode, a plurality of vent holes communicating with the water storage cavity are formed on a circumferential side wall of the power distribution box body in a penetrating mode, a supporting plate is welded to an inner wall of the water storage cavity, and an air bag is glued to an upper end of the supporting plate. The power distribution cabinet is advantaged in that the air bag absorbs the heat of the distribution box body and the outside to heat and evaporate the hot evaporation liquid in the air bag, the air bag is expanded, so the expansion volume of the air bag is increased, the stored rainwater can move upwards to be closer to the evaporation holes, the rainwater is affected by the external temperature to be increased, the rainwater can be evaporated more quickly to supplement into the air, the comfort of the external air is kept, and dryness caused by the high temperature is avoided.

The invention discloses a prescription of an intumescent filler for a fireproof package. The prescription disclosed by the invention is obtained by mixing the following components in parts by weight: 6-20 parts of char-forming agent, 6-20 parts of char-forming catalyst, 10-30 parts of foaming agent, 10-30 parts of inorganic reinforcement, 6-15 parts of inorganic filling agent and 15-45 parts of intumescent material. The prescription disclosed by the invention combines with inorganic filler and organic filler and uses the advantages thereof; fire-resistant barrier with a certain thickness and a certain strength can be intumesced and rapidly charred in a short time in fire, and heat is absorbed and non-flammable gases are released during intumescing and charring processes, so as to achieve the purposes of resisting fire, isolating head and isolating smoke. The prescription has high application value.

The invention belongs to the technical field of infusion soft bags, and specifically relates to a method for preparing a soft infusion bag; the infusion soft bag includes a bag body and a rubber stopper; a heating layer is fixedly connected to the inner wall of the bag; the bag body The bottom is wrapped with a rubber plug in the inner wall of the bag; a chute is opened in the inner wall of the rubber plug, and a slider is slidably connected in the chute; the upper surface of the slider is fixedly connected with an intubation tube; the inner surface of the intubation tube is A rubber bag is fixedly connected; a sealing layer is fixedly connected to the inner surface of the intubation above the rubber bag; a spacer is fixedly connected to the outer surface of the intubation above the sealing layer; the right side of the rubber plug is fixed to the inner wall of the bag It is connected with an air inlet pipe; the present invention is mainly used to solve the problem that in the production process of the current infusion soft bag, since no antibacterial material is added in the raw material, the effect of automatic sterilization cannot be achieved. External heating can not achieve the effect of heating up the medicine, and when the hanging needle is inserted into the infusion soft bag, sometimes there will be a problem of leakage.
