The utility model relates to the field of fire fighting, and provides a fire extinguishing device, an energy storage device and a power utilization device.The fire extinguishing device comprises a shell, the shell comprises a first wall and side walls, the side walls define a containing cavity with an opening, the opening covers the first wall, the first wall is provided with a first through hole and a second through hole, and the first through hole is used for spraying aerosol; the barrier is arranged on one side, far away from the accommodating cavity, of the first wall; the slow opening part is connected to the blocking part to slow down movement of the blocking part in the thickness direction of the first wall. Wherein the first through hole is at least partially formed outside the orthographic projection of the blocking part on the first wall, and the second through hole is formed inside the orthographic projection of the blocking part on the first wall, so that the reliability of the fire extinguishing device is improved.

This invention discloses a device for laying moisturizing material for tunnel concrete curing, relating to the field of road maintenance technology. It includes a material box with a discharge assembly inside, a pressurizing assembly on one side of the box's inner cavity, and a support plate fixedly connected to the bottom of the box. The support plate has multiple through-hole discharge holes. This invention improves the mixing degree of the moisturizing material. Through the rotation of two threaded rollers and the movement of the connecting window, the moisturizing material can be better mixed with other components, making the material more uniform and preventing settling and separation. The device improves the mixing degree of the moisturizing material within the box through squeezing and tumbling, thereby improving the quality of the paved road surface. It effectively improves the mixing degree of the moisturizing material and has the advantages of convenient material discharge and efficient operation. The synchronous movement of the drive roller and the boss increases the discharge pressure of the moisturizing material and increases the depth of the material, facilitating smooth discharge.

A discharge device according to one embodiment includes: a discharger containing and discharging a polymeric material; a sensing unit that senses a characteristic of the polymer material; and a control unit that controls a discharge pressure of the discharger in accordance with a sensing signal from the sensing unit.
