Description

Technical Field

[0001] The invention relates to the field of power distribution cabinets, in particular to an energy-saving and cooling power distribution cabinet. Background Art

[0002] The power distribution cabinet is an important device in the power system that receives electrical energy and distributes it to various circuits or equipment. It not only distributes power and controls the controlled terminal equipment, but also provides protection when the circuit has problems such as overload, short circuit, leakage, etc., and facilitates the troubleshooting of the circuit.

[0003] When designing and producing a distribution cabinet, the problem of heat generated by the operation of the internal electrical components will be taken into consideration. If the electrical components are in a high temperature environment for a long time, it will inevitably affect the stable operation of the electrical components. For this reason, heat dissipation holes are generally set on the cabinet body, or a forced exhaust cooling fan is set in the cabinet body.

[0004] In the actual use of the distribution cabinet, different types of electrical components are installed in the cabinet, and the operating loads are different, and the heat generated is also different. At the same time, the heat generated also varies with the peak or low peak of electricity consumption. If it is in the peak period of electricity consumption, the operating load of the electrical components is large, and the heat generated increases accordingly. The single heat dissipation hole on the cabinet makes it difficult to quickly dissipate the heat. Even if the forced exhaust cooling fan is enabled for heat dissipation, the forced exhaust cooling fan usually dissipates the heat for the entire cabinet, that is, each part of the cabinet receives the same heat dissipation. If a certain electrical component generates a lot of heat, it requires targeted and high-intensity heat dissipation. The above heat dissipation method is difficult to adapt to the heat dissipation and cooling protection of a certain electrical component, as well as the heat dissipation of the entire cabinet. Some parts of the cabinet do not need to be dissipated, which will cause energy waste.

The motor 8 drives the fan blades 10 to rotate through the rotating shaft 9. The fan blades 10 rotate and draw the outside wind from the through hole 5 into the cylinder 4, and the wind pressure in the cylinder 4 increases. Then the wind flows into the air supply pipe 7 from the air outlet 6, and the wind blows directly on the electrical components to achieve heat dissipation and cooling protection of the electrical components. Considering the problem that some electrical components generate a lot of heat, the ends of multiple air supply pipes 7 can be directed together to an electrical component with high heat generation, so that more air volume is blown on the electrical components, thereby improving the heat dissipation and cooling effect. After the outside wind exchanges heat with the heat generated by the electrical components, the hot air is discharged from the heat dissipation hole 2; the air supply pipe 7 is a telescopic bellows, and the air outlet end of the air supply pipe 7 can be bent to any position in the cabinet 1, and the outside wind is accurately blown at the position in the cabinet 1 that needs to be dissipated, thereby achieving rational use of energy.

The support plate 16 slides into the recess 17, and the semicircular grooves 18 of the support plate 16 and the semicircular grooves 18 on the cabinet body 1 form a socket. Then the cabinet door 19 is closed, and the latch 20 is inserted into the socket. The latch 20 supports the extended socket and further stabilizes the support plate 16. At the same time, the socket will squeeze the latch 20, squeezing the latch 20 into the socket, thereby locking the cabinet door 19.

[0066] At the same time, a blocking plate 24 is arranged inside each air outlet 6. When a certain air outlet 6 is not connected to the air supply pipe 7, the air outlet 6 can be blocked by the blocking plate 24, so that the wind of the cylinder 4 is fully discharged from the air outlet 6 connected to the air supply pipe 7, and the outside wind is reasonably utilized;

[0067] The specific method of the air outlet 6 and the air supply pipe 7 is that the cover body 25 is attached to the outside of the air outlet 6, and the top plate 27 is pressed against the upper half of the blocking plate 24, squeezing the blocking plate 24, forcing the blocking plate 24 to deflect into the cylinder 4.

[0086] At the same time, a blocking plate 24 is arranged inside each air outlet 6. When a certain air outlet 6 is not connected to the air supply pipe 7, the air outlet 6 can be blocked by the blocking plate 24, so that the wind of the cylinder 4 is fully discharged from the air outlet 6 connected to the air supply pipe 7, and the outside wind is reasonably utilized;

[0087] The specific method of the air outlet 6 and the air supply pipe 7 is that the cover body 25 is attached to the outside of the air outlet 6, and the top plate 27 presses the upper half of the blocking plate 24, squeezing the blocking plate 24, forcing the blocking plate 24 to deflect into the cylinder 4, at which time the air outlet 6 is opened and connected to the air supply pipe 7;

[0088] The motor 8 drives the rotating shaft 9 to rotate, and the multiple fan blades 10 rotate. The vibration force generated is unfavorable for the connection between the air supply pipe 7 and the air outlet 6, which may cause the cover body 25 to loosen from the cylinder body 4, or the cover body 25 to deviate from the air outlet 6. For this purpose, a plug plate 28 is provided. The cover body 25 is opposite to the air outlet 6, and the top plate 27 is pressed on the blocking plate 24. The blocking plate 24 deflects into the cylinder body 4. At the same time, the plug plate 28 is inserted into the gap between the rotating block 23 and the notch 21. At this time, the second card strip 30 on the lower surface of the rotating block 23 is engaged with the first card strip 29 on the plug plate 28 to fix the plug plate 28, thereby constraining and stabilizing the cover body 25.

[0089] When the top plate 27 is pressed against the blocking plate 24 and the top plate 27 moves along the side walls of the air outlet 6, the third clamping strip 31 is clamped on the side walls of the air outlet 6, further stabilizing the cover body 25 at the position of the air outlet 6;

[0090] The end of the branch pipe 15 is fixedly connected to the vertical plate 32, and the branch pipe 15 is connected to the drainage hole 34 in the slide groove 33. When the heat sink 35 is slidably installed in the slide groove 33, the water inlet hole 36 on the heat sink 35 is opposite to and connected to the drainage hole 34. The rainwater collected in the water collection tank 11 flows into the branch pipe 15 and then diverted to the heat sink 35. The outside wind blows on the heat sink 35 to cool the heat sink 35. Due to the continuous movement of water molecules, the water in the heat sink 35 will also exchange heat with the water in the branch pipe 15, and the water in the branch pipe 15 will be cooled, which is helpful for the heat dissipation of the cabinet 1.

[0091] The strip-shaped holes 37 provided on the heat sink 35 can enhance the heat dissipation effect of the water in the heat sink 35. At the same time, the heat sink 35 is movably connected to the slide groove 33 on the vertical plate 32, which is convenient for removing the heat sink 35 and cleaning the dirt inside the heat sink 35 and the branch pipe 15.

[0092] The lower end of the rotating shaft 9 is connected to the cylinder 4 through a supporting rod, and the upper end of the rotating shaft 9 is connected to the output end of the motor 8; the semi-cylindrical design of the upper end of the rotating shaft 9 and the semi-cylindrical setting of the output end of the motor 8 facilitate the installation of the cylinder 4; when installing the cylinder 4, the semi-cylindrical vertical surface of the upper end of the rotating shaft 9 is opposite to the rear side wall inside the cabinet 1, and then the bolt 39 is threadedly connected to the threaded hole 38 at the arc surface position of the upper end of the rotating shaft 9, and the bolt 39 does not penetrate the threaded hole 38 at the arc surface position of the upper end of the rotating shaft 9, and then the output end of the motor 8 is adjusted so that the semi-cylindrical vertical surface of the output end of the motor 8 faces the front port of the cabinet 1, and the support plate 16 slides into the recess 17. At this time, the semi-cylindrical vertical surface of the output end of the motor 8 is fitted together with the semi-cylindrical vertical surface of the upper end of the rotating shaft 9, and then a screwdriver or a hexagonal socket is used to penetrate the clearance port 40, and the bolt 39 is rotated, and the bolt 39 penetrates the threaded hole 38 on the rotating shaft 9 and the threaded hole 38 on the output end of the motor 8.
