This invention discloses a power supply device for safety engineering equipment on construction sites, relating to the field of power supply devices. It includes a power cabinet and multiple batteries. The power cabinet is cylindrical with a notch on one side, where a side filter is installed. It should be noted that, in this embodiment, when the batteries are in use, the radial layout effectively increases the gap between batteries while ensuring the number of batteries is sufficient, increasing airflow and improving heat dissipation. A combination of central heat dissipation and rotating lateral heat dissipation ensures uniform heat dissipation for each battery, eliminating localized hotspots, improving heat dissipation efficiency, extending battery life, and reducing maintenance costs and replacement frequency. Furthermore, the sliding filter plate can slide open, directly exposing the batteries to further enhance heat dissipation. When not dissipating heat, it closes, providing ample protection against dust, moisture, and impact.

The utility model relates to the technical field of iris valves, and discloses a high-sealing iris valve which comprises a mounting seat, a supporting plate is fixedly mounted on the side face of the mounting seat, and a valve body is fixedly mounted at the end of the supporting plate. Due to the design of the valve plates, the main sealing strip, the secondary sealing strip, the main sealing groove and the secondary sealing groove, opening and closing operation is achieved through mutual matched rotation of the six valve plates, and meanwhile the main sealing strip and the secondary sealing strip between every two adjacent valve plates are in an embedded state with the main sealing groove and the secondary sealing groove all the time. The main sealing strip and the secondary sealing strip are matched with the main sealing groove and the secondary sealing groove, the main sealing strip and the secondary sealing strip move along with the valve plates in the moving process and are embedded along with the valve plates in the closing process, and therefore two layers of crossed areas are formed between the contact faces of every two adjacent valve plates, and poor sealing performance caused by excessive abrasion of the smooth faces is prevented. According to the technical scheme, the sealing performance of the contact faces between the valve plates is improved, and the technical problem that the sealing performance is poor is solved.
