Description

Technical Field

[0001] The present invention relates to the technical field of intelligent heat dissipation of ring main units, and particularly relates to an intelligent heat dissipation integrated primary and secondary ring main unit. Background Art

[0002] With the continuous development of society and the rapid changes in technology, the application scope of ring main units has become increasingly wide, and their importance in the power distribution and transmission system has become increasingly prominent. At the same time, the functions of ring main units have become increasingly rich and diverse, which directly promotes the continuous increase in the number of power devices installed inside the ring main unit. However, the intensive deployment of power equipment, although improving the comprehensive performance of the ring main unit, inevitably brings the problem of rising internal temperature. When a large amount of heat generated by a large number of power devices during high-intensity and long-term operation cannot be dissipated in a timely and effective manner, the temperature inside the ring main unit will rise rapidly, which poses a serious threat to the safe and stable operation of power devices.

[0003] To ensure that the ring main unit and its internal power devices can work continuously and reliably, it is necessary to effectively dissipate heat inside the ring main unit. Unfortunately, most of the currently widely used heat dissipation devices adopt an overall heat dissipation strategy, that is, an undifferentiated heat dissipation treatment for the entire inside of the ring main unit. This "one-size-fits-all" heat dissipation method often requires high energy consumption, not only causing waste of precious resources, but also being unable to cope when facing local high-temperature areas inside the ring main unit, and being difficult to reduce the temperature of these key areas in a timely and accurate manner. This phenomenon of uneven heat dissipation undoubtedly exacerbates the risk of abnormal temperature rise inside the ring main unit, and may even trigger the overheat protection mechanism of power devices, or even directly cause equipment damage, affecting the safe and stable operation of the entire power system. Summary of the Invention

[0004] In view of the above problems, the present invention provides an intelligent heat dissipation integrated primary and secondary ring main unit to solve the problem of high energy consumption required for undifferentiated heat dissipation treatment inside the ring main unit.

[0012] Preferably, the adjustment mechanism further includes an adjustment cylinder disposed inside the conical air guide cylinder and connected to a rotating cylinder.

[0013] Preferably, the adjustment cylinder is located in the spacing between the lower air duct and the upper air duct.

[0014] Preferably, some heat dissipation mechanisms correspond to the adjustment mechanisms one by one. One partial heat dissipation mechanism cooperates with one adjustment mechanism, and both of these mechanisms are provided in multiple numbers, respectively for intake and exhaust, facilitating the formation of an air duct for heat dissipation.

The power unit 15 includes a gear and a motor, the shaft of the motor is fixedly connected to the gear, and the motor is fixedly installed on the outer wall of the inner housing 2; the motor provided in the power unit 15 drives the gear to rotate, and then drives the gear provided on the rotating ring 14 to rotate, and then drives the rotating ring 14 to perform a rotating operation; a hole is provided in the middle of the rectangular adjustment plate 16 for installing the exhaust hose 13, and the rectangular adjustment plate 16 can be tilted to facilitate adjusting the position of the outlet of the exhaust hose 13; there are two telescopic rods 17 arranged symmetrically like a mirror image, one end of the telescopic rod 17 is ball-jointed to the rectangular adjustment plate 16, and the other end is slidably installed in the chute provided on the rotating ring 14; one end of the scissors frame 18 is threadedly connected to the lead screw 19 through a connecting block, and the other end is ball-jointed to the rectangular adjustment plate 16 through a ball head; one end of the lead screw 19 is connected to the motor, the motor is fixedly installed in the groove provided on the rotating ring 14, and at the same time the lead screw 19 is rotatably connected to the rotating ring 14; the adjustment rotating cylinder 20 is arranged inside the conical air guide cylinder 8, and at the same time two holes are provided on the adjustment rotating cylinder 20 for discharging air through the holes into the lower air duct 9 and the upper air duct 10; a shaft is provided under the adjustment rotating cylinder 20, and the end of the shaft is connected to a rotating cylinder, which is used to drive the adjustment rotating cylinder 20 to rotate, so as to control the air flow direction. The rotating cylinder is installed inside the exhaust hose 13 through a baffle; after the rotating cylinder drives the adjustment rotating cylinder 20 to rotate, the holes provided on the adjustment rotating cylinder 20 no longer discharge air into the lower air duct 9 and the upper air duct 10, and then discharge the air into the conical air guide cylinder 8, and then discharge it into the inner housing 2 through the exhaust hose 13.

[0035] As shown in the embodiment Figures 5 - 8 As shown in the figure, part of the heat dissipation mechanism includes: small fans 7, a conical air guide cylinder 8, and an exhaust hose 13; there are multiple small fans 7 respectively installed on the front and rear sides of the outer housing 1. The small fan 7 installed on the front side of the outer housing 1 is used for air intake, and the small fan 7 installed on the rear side of the outer housing 1 is used for air exhaust. One air intake and one air exhaust form an air path, and the devices in the air path can be effectively and quickly cooled; one end of the conical air guide cylinder 8 is fixedly installed on the inner wall of the outer housing 1 and covers the inner side of the small fan 7. The conical air guide cylinder 8 is provided with a pipe hole, and the other end of the conical air guide cylinder 8 is fixedly connected to the exhaust hose 13. The exhaust hose 13 passes through the inner housing 2 and enters the inside of the inner housing 2, and the end of the exhaust hose 13 entering the inside of the inner housing 2 is fixedly installed in the hole provided in the middle of the rectangular adjustment plate 16.

[0036] As shown in the embodiment Figures 4 - 5As shown in the figure, the overall heat dissipation mechanism includes: a large-displacement fan 4, a lower air duct 9, an upper air duct 10, an upper connecting pipe 11, and a lower connecting exhaust pipe 12. There are two large-displacement fans 4. One is fixedly installed at the upper end of the inner housing 2 for exhausting air, and the other is fixedly installed in the hole of the bottom plate of the outer housing 1 for intake air. One end of the lower air duct 9 is inserted into the conical air guide cylinder 8. One end of the upper air duct 10 is inserted into the conical air guide cylinder 8. There is a gap between the lower air duct 9 and the upper air duct 10, and an adjusting rotary cylinder 20 is provided in the gap. The other end of the lower air duct 9 is connected to the upper air duct 10 in another overall heat dissipation mechanism. The uppermost upper air duct 10 is connected to the upper connecting pipe 11, and the lowermost lower air duct 9 is connected to the lower connecting exhaust pipe 12. A passage is formed through multiple lower air ducts 9, multiple upper air ducts 10, the upper connecting pipe 11, and the lower connecting exhaust pipe 12, and then the air inhaled by multiple small fans 7 is integrally discharged into the inner housing 2. The lower connecting exhaust pipe 12 is provided with multiple short pipes for exhausting air, and the gas is integrally discharged into the inner housing 2. Similarly, multiple small fans 7 for exhausting air can discharge the air inside the inner housing 2 to the outside of the device through the formed passage, accelerating the air circulation inside the device, and then improving the heat dissipation efficiency inside the inner housing 2.

[0037] For example, in the embodiment Figure 4 As shown in the figure, the partial heat dissipation mechanisms and the adjustment mechanisms correspond one by one. One partial heat dissipation mechanism cooperates with one adjustment mechanism, and there are multiple of both of these mechanisms, which are respectively used for intake air and exhaust air, facilitating the formation of an air duct for heat dissipation.

[0038] Working principle: When using this device, first install the power device inside the device, and then move the device to the designated position for work. When the overall temperature inside the device rises, after multiple temperature sensing modules 5 sense that the overall temperature inside the inner housing 2 has risen, the small fans 7 for intake air provided on this device start to work, and the external gas flows into the inner housing 2 through the lower air duct 9, the upper air duct 10, the upper connecting pipe 11, and the lower connecting exhaust pipe 12, and then is discharged through the large-displacement fan 4. Then, an air duct for rapid heat dissipation is formed to dissipate heat from all the power devices inside the inner housing 2. It is also possible to form an air duct through the small fans 7 for exhaust air and the large-displacement fan 4 for intake air installed on the bottom plate of the outer housing 1 for heat dissipation. At the same time, both of these two air ducts for heat dissipation can be opened for faster heat dissipation. During the rapid heat dissipation process, the fans act with high power. At this time, the rapidly flowing air current will cause the device to shake. At this time, the shock-absorbing springs 3 will weaken the shaking of the device, preventing the power device installed inside the inner housing 2 from being damaged during large-scale shaking.

[0039] Meanwhile, when a temperature sensing module 5 provided inside the inner housing 2 senses an increase in the temperature at a position inside the inner housing 2, at this time, two small fans 7 corresponding to the position of the temperature sensing module 5 respectively exhaust air and enter. The adjustment rotary cylinder 20 rotates driven by a rotary cylinder. The adjustment rotary cylinder 20 blocks the lower air duct 9 and the upper air duct 10, and discharges the gas entering the adjustment rotary cylinder 20 into the conical air guide cylinder 8. At this time, the gas entering through the small fan 7 enters the conical air guide cylinder 8, then enters the exhaust hose 13 through the conical air guide cylinder 8, then flows into the inner housing 2 through the exhaust hose 13, and then the exhaust hose 13 connected to the small fan 7 for exhausting gas discharges the inflowing gas through the exhaust hose 13 and then enters the conical air guide cylinder 8 and then discharges from the small fan 7 for exhausting gas. At this time, a special air duct for the temperature rise at the specified position is formed to dissipate heat from the specified position;

[0040] Meanwhile, when the temperatures at multiple positions rise and the rising speed is slow, it is easy to cause waste of the small fans 7 when using the corresponding small fans 7 for heat dissipation. At this time, two obliquely corresponding small fans 7 are used for heat dissipation. At this time, the devices on this inclined air duct can all dissipate heat, avoiding the waste of resources caused by using multiple small fans 7 to dissipate heat at multiple positions respectively;

[0041] During the process of using the inclined air duct for heat dissipation, the power unit 15 drives the rotary ring 14 to rotate, the motor connected to the lead screw 19 drives the lead screw 19 to rotate, and then drives the scissors frame 18 to lift, and then drives the rectangular adjustment plate 16 to incline, so as to adjust the position of the opening of the exhaust hose 13, facilitating the alignment of the positions of the openings of the exhaust hoses 13 connected to the two small fans 7. Then, the gas entering through the small fan 7 for air intake is discharged into the inner housing 2 through the exhaust hose 13, and then can accurately enter the exhaust hose 13 connected to the small fan 7 for exhausting gas, facilitating the discharge of the gas. In this way, the entering gas can accurately flow to the discharge position, thereby reducing the loss of gas caused by the turbulent flow of gas inside the inner housing 2 and affecting the heat dissipation effect;

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
