This invention relates to the field of electrical equipment cabinet technology, specifically to an energy-saving and heat-dissipating power electrical control cabinet. The cabinet includes a control unit with a first partition dividing the space within it into an air intake chamber and an equipment chamber. A heat dissipation mechanism is also provided within the control unit, including an air intake assembly located within the air intake chamber. This assembly comprises a main air intake duct, several air outlet ducts, and several mounting plates. Several mounting holes are provided on the side of the first partition near the air intake chamber. Through holes are provided on the mounting plates, and fixing bolts are installed within these through holes and screwed into their corresponding mounting holes. This energy-saving and heat-dissipating power electrical control cabinet overcomes the problem of insufficient localized temperature reduction in existing heat dissipation methods. Furthermore, the position of the heat dissipation vents can be flexibly adjusted to address the issue of adjusting the position of equipment within the power electrical control cabinet.

An outdoor self-cleaning power distribution cabinet includes a cabinet body, an air guide assembly, and a dust filter box. The dust filter box includes a box body and multiple piston cylinders installed inside the box body. Each piston cylinder has an air inlet at its bottom, and an exhaust window is provided between any two adjacent piston cylinders. The lower end of each piston cylinder has a mesh screen for airflow. Inside the piston cylinder is a piston that slides back and forth on the inner wall of the mesh screen. As the piston slides, it scrapes away dust adhering to the surface of the mesh screen. The dust filter box with a piston structure at the air inlet ensures that the piston head completes a reciprocating scraping motion within the mesh screen each time the fan starts and stops, automatically removing dust accumulated on the outer surface of the mesh. This process requires no manual intervention, maintaining a clean state and ensuring the normal operating life and reliability of the electrical equipment.

This utility model discloses a blower room, relating to the technical field of blower room technology. It includes a blower room body with a ventilation window at the upper front end. Mounting rails are fixedly installed on both sides of the ventilation window at the upper rear end of the blower room body, and a filter mechanism is slidably connected inside the mounting rails. This utility model adopts the above structure. The device, through the cooperation of a drive mechanism and a filter mechanism, starts a drive motor to rotate a gear, which in turn rotates a gear ring, causing a slip ring and a brush plate to rotate within a conical filter screen. The conical filter screen, being conical in shape, increases the filtration and ventilation area, improving filtration efficiency. Its inclined surface can quickly remove dust, improving dust cleaning efficiency. Overall, it can maintain the ventilation efficiency and heat dissipation effect inside the blower room for a long time, maximizing the service life of the blower. The rotating brush plate effectively cleans the inside of the conical filter screen, ensuring good ventilation.

The utility model discloses a cable conduit plugging sealing element installation structure, and belongs to the technical field of sealing elements. The cable conduit plugging sealing element mounting structure comprises a lower sealing element, an upper sealing element hinged to the lower sealing element, and a mounting cavity formed in the lower sealing element and the upper sealing element, the rubber ring bag cavity is arranged in the mounting cavity; the fixing mechanism is arranged on one side of the lower sealing piece and is used for quickly sleeving a cable with the rubber ring bag cavity; through the cooperative use of the devices and the arrangement of the fixing mechanism, the lower sealing piece and the upper sealing piece can be opened, and then the cable and the rubber ring bag cavity are placed at proper positions, so that the rubber ring bag cavity can be completely expanded to the required position, the cable pipeline can be effectively plugged, the sealing performance is improved, and the service life of the cable is prolonged. Impurities such as water, gas or dust are prevented from entering a cable pipeline, and normal operation and service life of the cable are ensured.
