Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to a power control device. Background Art

[0002] The distribution box is an important power control device. It is a low-voltage distribution box that is assembled in a closed or semi-enclosed metal cabinet or on a screen according to electrical wiring requirements, including switchgear, measuring instruments, protective devices, and auxiliary equipment. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In the event of a fault or abnormal operation, the protective device can cut off the circuit or alarm. Measuring instruments can display various operating parameters, adjust certain electrical parameters, and provide prompts or signals when deviations from normal operating conditions occur. With the increasing maturity of Internet of Things technology, power control devices can be connected to mobile phone apps through the Internet, enabling mobile terminal control and monitoring.

[0003] However, in the power control device, a large number of electrical components will generate a lot of heat due to resistance during use. However, the use of electrical components has certain requirements on the temperature of the use environment. If the temperature inside the power control device is high, higher than the adaptable temperature of the electrical components, working in this condition for a long time will double the risk of accidents involving the electrical components.

A heat sink (9) is also fixedly connected to the inside of the box body (6), and the heat sink (9) includes a heat absorbing fin plate (91) and a mounting plate (92). The heat absorbing fin plate (91) includes a frame, and several parallel mounting rods are provided inside the frame. A group of copper heat absorbing plates are fixed on the mounting rods. A group of fans (93) are provided on the mounting plate (92). The wind direction of the fans (93) is from the inside of the box body (6) to the outside of the box body (6). The fans (93) are arranged between the gauze (7) and the heat absorbing fin plate (91).

[0027] The box body (1) is provided with a mounting plate (13) inside, and the mounting plate (13) is provided with mounting holes for facilitating the installation of electrical parts. A set of slide rails (11) is fixed inside the box body (1), and the slide rails (11) are divided into two parts and fixed on opposite sides of the box body (1) and staggered, so that a serpentine channel is presented between a set of baffles (12). Each slide rail (11) is plugged and slidably connected with a baffle (12), and the baffles (12) are arranged between the two ventilation holes (10), so that the air between the baffles (12) can move a greater distance and take away more heat. The baffles (12) are slidably connected to the mounting plate (13), and an S-shaped ventilation duct is formed between the baffles (12). A blast plate (14) is provided on the lower side of the box body (1), and a blast pipe (8) is provided on one side of the blast plate (14). The blast pipe (8) passes through the box body (1) and extends to the outside of the box body (1).

[0028] The mounting plate (13) is provided with a plurality of air outlet holes, each of which is inlaid with a nozzle (15). The blast plate (14) and the mounting plate (13) are fixedly connected to form an L-shaped plate. The blast plate (14) and the bottom wall of the box body (1) form a cavity A, and the mounting plate (13) and the rear wall of the box body (1) form a cavity B. Cavity A and cavity B form a through cavity, which is an air supply channel. The air supply channel is connected to the S-shaped ventilation duct through the nozzle (15). The nozzle (15) is threadedly connected to the corresponding position of the mounting plate (13). The nozzle (15) includes a spiral tube (151). The other end of the spiral tube (151) is rotatably connected to the rotating tube (152). One end of the rotating tube (152) is provided with a group of grooves (153). Each groove (153) is provided with an elastic sheet (155). Each groove (153) is provided with an air injection hole (156). One end of the rotating tube (152) is spirally connected to a tightening bolt (157), and an ellipsoid (158) is sleeved on the outside of the tightening bolt (157). The ellipsoid (158) is correspondingly arranged with the elastic sheet (155). By rotating the tightening bolt (157), the ellipsoid (158) moves in the direction of the elastic sheet (155). When the ellipsoid (158) contacts the elastic sheet (155), the bolt (157) is continuously tightened, so that the ellipsoid (158) presses the elastic sheet (155) to cause elastic deformation. When the elastic sheet (155) bends, the gas ejected from the air jet hole (156) is blown out in the direction of the elastic sheet (155). Therefore, rotating the tightening bolt (157) can change the direction of the gas ejected from the air jet hole (156). Changing the direction of the airflow can adapt to the heat dissipation of electrical components of different lengths, thereby increasing the heat dissipation effect.

[0029] It should be noted that, when in use, first fix the mounting plate (13) and the blast plate (14), then fix all the slide rails (11), and after the slide rails (11) are fixed, insert the baffle (12) into the corresponding slide rail (11). The baffle (12) can not only increase the movement distance of the wind in the box (1) but also prevent certain tools from being on it. In the next case where the staff forgets to bring tools for emergency use, they can continue to tighten the bolts (15) when the ellipsoid (158) contacts the elastic sheet (155). 7), the ellipsoid (158) can compress the elastic sheet (155) to cause elastic deformation. When the elastic sheet (155) bends, the gas ejected from the jet hole (156) is blown out in the direction of the elastic sheet (155). Therefore, rotating and tightening the bolt (157) can change the direction of the gas ejected from the jet hole (156). After the adjustment is completed, the box door (2) is closed, and the gas is ejected through the blast pipe (8), the mounting plate (13) and the blast pipe (14), and finally through the nozzle (15). Finally, the heat is taken out by the fan (93).
