Description

Technical Field

[0001] The present invention relates to the technical field of ring network boxes, and in particular to a primary and secondary fused ring network box. Background Art

[0002] The ring main box with integrated primary and secondary functions is an important component of the modern power distribution system. It integrates traditional primary equipment and intelligent secondary equipment, and achieves the perfect integration of the two through advanced technical means. This type of ring main box plays a key role in improving the reliability of power supply, reducing power outage time and optimizing power grid operation.

[0003] From a structural point of view, the primary and secondary integrated ring network box takes the primary and secondary integrated ring network cabinet as the core, supplemented by key components such as high-voltage incoming line cabinet and low-voltage incoming line cabinet, to build an efficient and stable power distribution system. Since the ring network box wraps the ring network cabinet from the outside, when dissipating heat, under the action of the cooling fan, the outside air first enters the ring network box, then enters the ring network cabinet, and then is discharged from the inside of the ring network cabinet to the inside of the ring network box, and then discharged from the ring network box to the outside, forming a heat dissipation cycle. This structural design itself has an impact on the heat dissipation efficiency;

[0004] In addition to the above factors, most of the existing cabinet-type power equipment uses cooling fans for heat dissipation. Its purpose is to exchange the high-temperature gas in the cabinet with the low-temperature gas outside, so as to cool the inside of the cabinet. However, the temperature in most parts of my country now exceeds 30 degrees in summer, and the surface temperature reaches 50 degrees or even higher. The heat dissipation window of the ring network box is generally set at a position close to the ground. Therefore, during the heat dissipation cycle, the air exchanged from the outside will be higher than the temperature of the air inside the box, which will cause the temperature inside the box to be too high, which is easy to cause damage to the internal components of the ring network box. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the traditional heat dissipation method cannot normally dissipate the heat inside the ring network box when the external temperature is too high, and to propose a primary and secondary fusion ring network box.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A primary and secondary fusion ring network box, comprising a box body and a box door hinged at the front end of the box body, and also comprising heat dissipation components arranged on both sides of the box body, the heat dissipation components comprising heat dissipation windows arranged on both sides of the box body, heat dissipation fans are movably connected to both sides of the box body, and a cooling component for dissipating heat inside the box body is arranged below the heat dissipation fan inside the box body;

[0008] The cooling component includes a telescopic component movably connected to the outside of the cooling fan output shaft, a gap is left at the inner rear end of the box body for use as a heat dissipation channel, and a water tank is movably connected to the bottom of the gap, a push nozzle is movably connected to one side of the top of the water tank, and an atomizing spray hole is opened at the top rear end of the push nozzle.

[0009] As a further description of the above technical solution:

[0010] The telescopic component includes a sleeve movably sleeved on the outside of the heat dissipation fan output shaft, a telescopic spring is fixedly connected between the inside of the sleeve and the heat dissipation fan output shaft, an eccentric wheel is fixedly sleeved on the outside of the sleeve, and the inside of the sleeve is filled with petroleum wax.

[0011] As a further description of the above technical solution:

[0012] The eccentric wheel consists of a fixed part and a movable part. The fixed part is fixedly sleeved on the outside of the sleeve. A spring hinge is movably connected between the fixed part and the movable part on a side close to the heat dissipation fan. The elastic force of the spring hinge is greater than the gravity of the movable part.

[0013] As a further description of the above technical solution:

[0014] The heat dissipation window is composed of a frame and louvers. There are a plurality of louvers distributed in a vertical linear array inside the frame. A rotating shaft is movably connected between the louvers and the frame.

[0015] As a further description of the above technical solution:

[0016] An adjustment component is provided between the heat dissipation window and the telescopic component, and the adjustment component includes a rack rotatably connected to the side of the sleeve close to the heat dissipation window, a gear is fixedly connected to the rear of the rotating shaft, a plurality of gears are meshedly connected with a tooth chain, a tooth groove meshing with the gear is provided on the inner side of the tooth chain, and teeth meshing with the rack are provided on the outer side of the tooth chain, and the rack slides through the interior of the frame and is limited by the frame.

[0017] As a further description of the above technical solution:

[0018] A replenishment assembly is provided at the rear end of the box body, and the replenishment assembly includes a water reservoir fixedly connected to the rear end of the box body, a filter is movably connected to the top of the water reservoir, a water pipe is fixedly connected between the bottom of the water reservoir and the water tank, and a one-way valve is provided inside the water pipe.

[0019] As a further description of the above technical solution:

[0020] The top of the box body is fixedly connected with a drainage eaves, and a cabinet body is arranged inside the box body.

[0021] As a further description of the above technical solution:

[0022] The water tank is C-shaped and wraps around the cabinet body, and the distance that the drainage eaves extend out of the cabinet body is less than the width of the water tank.

[0023] As a further description of the above technical solution:

[0024] Both sides of the box body are provided with shielding components, and the shielding components are composed of three baffles, and through holes are staggeredly opened on the baffles.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] By utilizing the effect of high temperature, the petroleum wax inside the sleeve melts and increases in volume when it changes from solid to liquid, thereby pushing the sleeve to slide along the surface of the output shaft of the heat dissipation fan, and pulling the telescopic spring to stretch during the sliding process. After the sleeve moves, the eccentric wheel outside it will synchronously move to the top of the pressing nozzle. At this time, the rotation of the heat dissipation fan drives its output shaft to rotate, and the rotation of the output shaft drives the sleeve and the eccentric wheel to rotate synchronously. Since the bottom of the eccentric wheel is located below the pressing nozzle when it is vertically downward, the pressing nozzle is intermittently pressed as the eccentric wheel rotates, so that the water inside the water tank is sprayed upward from the atomizing nozzle hole under the action of the pressing nozzle. The sprayed water is in an atomized state and can be evaporated instantly under the action of high temperature. A large amount of heat will be absorbed during the evaporation of water, thereby effectively dissipating heat and cooling the interior of the box. At the same time, it can be reset after the temperature drops, and water spraying and cooling operations will not be performed under low temperature conditions, thereby avoiding the atomized water sprayed at low temperature from being unable to evaporate, causing damage to the electrical components inside the box.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] like Figure 1-Figure 5 and Fig.10 and Fig.11 As shown, the present invention provides a primary and secondary fusion ring network box: comprising a box body 10 and a box door 20 hinged at the front end of the box body 10, a drainage eave 80 is fixedly connected to the top of the box body 10, a cabinet 90 is arranged inside the box body 10, and also comprises a heat dissipation component 30 arranged on both sides of the box body 10, the heat dissipation component 30 comprises a heat dissipation window 31 arranged on both sides of the box body 10, both sides of the inside of the box body 10 are movably connected with a heat dissipation fan 32, and a cooling component 50 for dissipating heat inside the box body 10 is arranged below the heat dissipation fan 32 inside the box body 10;

[0050] The cooling component 50 includes a telescopic component 54 movably connected to the outside of the output shaft of the cooling fan 32. A gap is left at the rear end of the interior of the box body 10 as a cooling channel, and a water tank 51 is movably connected to the bottom of the gap. A pressing nozzle 52 is movably connected to one side of the top of the water tank 51, and an atomizing nozzle 53 is opened at the rear end of the top of the pressing nozzle 52.

[0051] The telescopic assembly 54 includes a sleeve 541 movably sleeved on the outside of the output shaft of the cooling fan 32, a telescopic spring 543 is fixedly connected between the inside of the sleeve 541 and the output shaft of the cooling fan 32, an eccentric wheel 542 is fixedly sleeved on the outside of the sleeve 541, and the inside of the sleeve 541 is filled with petroleum wax;

[0052] The eccentric wheel 542 is composed of a fixed portion 5421 and a movable portion 5422. The fixed portion 5421 is fixedly sleeved on the outside of the sleeve 541. A spring hinge 5423 is movably connected between the fixed portion 5421 and the movable portion 5422 at a side close to the heat dissipation fan 32. The elastic force of the spring hinge 5423 is greater than the gravity of the movable portion 5422.

[0053] Shielding components 40 are disposed on both sides of the box body 10 . The shielding components 40 are composed of three baffles 41 , and through holes 42 are staggeredly formed on the baffles 41 .

[0054] Specifically, the functions of the primary and secondary sides of the main transformer are first integrated into one device to form a primary-secondary integrated ring network cabinet, and then the primary-secondary integrated ring network cabinet is used as the core, supplemented by key components such as high-voltage incoming line cabinet and low-voltage incoming line cabinet to form a cabinet body 90, to build an efficient and stable power distribution system, and the power distribution system is placed in the box body 10 to form a primary-secondary integrated ring network box, the front hinged box door 20 of the box body 10 is used to open the box body 10 to operate and repair the power distribution system, and heat dissipation components 30 are set on both sides of the box body 10 to dissipate heat inside the box body 10. In order to utilize the principle of natural convection, improve the heat dissipation efficiency and reduce the condensation water generated by the temperature difference, the heat dissipation components 30 of the general power distribution equipment are generally set at the bottom. In addition, because the surface temperature often reaches fifty degrees or even higher in the hot summer weather, the traditional heat dissipation method cannot achieve effective heat dissipation and cooling of the inside of the ring network box;

[0055] Based on this, under normal temperature, the heat dissipation fan 32 works, and the external airflow is sucked into the interior of the box body 10 through the heat dissipation window 31 on one side of the ring network box, and the high-temperature gas generated by the operation inside the box body 10 is dissipated and then discharged to the outside through the other side of the ring network box, thereby completing the heat dissipation and cooling operation inside the ring network box. When the external temperature rises and the interior of the ring network box cannot be effectively cooled, the petroleum wax inside the sleeve 541 melts under the action of high temperature, and the volume of the petroleum wax increases when it changes from solid to liquid, thereby pushing the sleeve 541 to slide along the output shaft surface of the heat dissipation fan 32, and pulling the telescopic spring 543 to stretch during the sliding process. After the sleeve 541 moves, the eccentric wheel 542 outside it will move synchronously to the top of the pressing nozzle 52. At this time, the rotation of the heat dissipation fan 32 drives its output shaft to rotate, and the rotation of the output shaft drives the sleeve 541 and the eccentric wheel 542 to rotate synchronously, When the eccentric wheel 542 is vertically downward, its bottom is located below the pressing nozzle 52. Therefore, as the eccentric wheel 542 rotates, the pressing nozzle 52 is intermittently pressed, so that the water inside the water tank 51 is sprayed upward from the atomizing nozzle hole 53 under the action of the pressing nozzle 52. The sprayed water is in an atomized state and can be evaporated instantly under the action of high temperature. A large amount of heat will be absorbed during the evaporation process of the water, thereby effectively dissipating heat and cooling the interior of the box body 10. It should be noted that the pressing nozzle 52 belongs to the prior art, and its structure and principle belong to the common knowledge in this field, so it will not be elaborated in detail here. In addition, a telescopic rod is provided between the sleeve 541 and the output shaft of the heat dissipation fan 32. One of the purposes is to limit the telescopic spring 543 and at the same time realize the fixing of the torsion direction between the sleeve 541 and the output shaft of the heat dissipation fan 32, so as to ensure that the sleeve 541 can rotate synchronously with the output shaft of the heat dissipation fan 32.

[0056] In addition, the eccentric wheel 542 is designed to consist of a fixed part 5421 and a movable part 5422, which are connected by a spring hinge 5423, so that when the sleeve 541 moves, if the eccentric wheel 542 is in contact with the pressing nozzle 52 in the vertical downward process, under the reaction force applied by the pressing nozzle 52 to the eccentric wheel 542, the movable part 5422 of the eccentric wheel 542 will rotate to the side away from the pressing nozzle 52 with the spring hinge 5423 as the turning point, until the eccentric wheel 542 moves with the sleeve 541 to the top of the pressing nozzle 52, and then under the elastic recovery action of the spring hinge 5423, the movable part 5422 of the eccentric wheel 542 rotates to the initial state;

[0057] Afterwards, the sprayed atomized water passes through the gap at the rear of the box 10 together with the outside air and is discharged from the heat dissipation window 31 on the other side of the box 10. It should be noted that the electrical components inside the box 10 are all arranged inside the cabinet 90, and the side of the cabinet 90 is in a closed state, so the sprayed atomized water will not cause damage to the electrical components inside the cabinet 90 from the side of the cabinet 90. However, considering that a heat dissipation area is provided at the rear end of the cabinet 90, in order to prevent the atomized water from not being able to evaporate in time and entering the inside of the cabinet 90 from the rear of the cabinet 90 and attaching to the electrical components to cause circuit failure, shielding components 40 are specially arranged on both sides of the inside of the box 10, so that the atomized water flows in a serpentine path when passing through the through holes 42 staggered on the three-layer baffle 41, and then the baffle 41 is used to effectively intercept the water that has not completely evaporated, thereby preventing the water vapor from damaging the electrical components;

[0058] Finally, it should be explained that since the cooling fan 32 inside the power distribution equipment works continuously throughout the year, and the melting point of petroleum wax is between 30-35 degrees, the daytime temperature in summer is enough to melt it. Because there is a temperature difference between day and night in summer, when the outside temperature drops below 30 degrees at the end of summer and late at night in summer, the original cooling fan 32 can effectively cool the inside of the box 10. At this time, under the action of low temperature, the petroleum wax inside the sleeve 541 solidifies. During the solidification process, the telescopic spring 543 resets and pulls the sleeve 541 back, so that the sleeve 541 drives the eccentric wheel 542 to reset, so that the eccentric wheel 542 and the pressing nozzle 52 are dislocated and separated and no longer press the pressing nozzle 52. Therefore, water spraying and cooling operations will not be performed under low temperature conditions, avoiding the atomized water sprayed at low temperature from being unable to evaporate and causing damage to the electrical components inside the box 10.

[0059] like Figure 3 , Figure 6 and Figure 7 As shown, the heat dissipation window 31 is composed of a frame 311 and louvers 312. There are multiple louvers 312 distributed in a vertical linear array inside the frame 311. A rotating shaft 313 is movably connected between the louvers 312 and the frame 311.

[0060] An adjustment component 60 is provided between the heat dissipation window 31 and the telescopic component 54. The adjustment component 60 includes a rack 61 rotatably connected to the sleeve 541 on the side close to the heat dissipation window 31. A gear 62 is fixedly connected to the rear of the rotating shaft 313. A plurality of gears 62 are meshedly connected with a tooth chain 63. A tooth groove 631 meshing with the gear 62 is provided on the inner side of the tooth chain 63. Teeth 632 meshing with the rack 61 are provided on the outer side of the tooth chain 63. The rack 61 slides through the interior of the frame 311 and is limited by the frame 311, so that the rack 61 can only move horizontally and will not rotate with the sleeve 541.

[0061] Specifically, when the sleeve 541 in the telescopic assembly 54 moves toward the side close to the heat dissipation window 31, it will push the rack 61 to move synchronously. At this time, since the rack 61 is meshed with the teeth 632 on the outside of the toothed chain 63, it will drive the toothed chain 63 to rotate. Since the toothed groove 631 on the inside of the toothed chain 63 is meshed with the gear 62 on the outside of the rotating shaft 313, the toothed chain 63 rotates and drives the gear 62 to rotate synchronously, and then the gear 62 drives the louvers 312 to rotate synchronously through the rotating shaft 313, so that the originally vertical louvers 312 rotate to a horizontal state, thereby expanding the gap between adjacent louvers 312, allowing the outside air to enter and exit the interior of the box 10 more quickly, thereby accelerating the heat dissipation efficiency, further improving the heat dissipation effect inside the box 10, and in a low temperature environment, as the sleeve 541 is reset, the rack 61 is driven to rotate. The bar 61 moves back, causing the tooth chain 63 and the gear 62 to rotate, thereby causing the originally horizontal louver 312 to rotate to a vertical state, reducing the gap between adjacent louvers 312, slowing down the speed at which outside air enters and exits the box body 10, and avoiding the excessively fast heat dissipation efficiency in winter that causes the internal temperature of the box body 10 to be too low, causing the electrical components to fail or even be damaged, so that the ring network box can adjust the cooling method according to different weather conditions. While ensuring the cooling efficiency, it also ensures the safety of the electrical components inside the box body 10. In addition, the louver 312 can be driven when the temperature drops in the middle of the night in summer, so that the vent of the heat dissipation window 31 becomes smaller. On the one hand, it can reduce the probability of dew caused by the temperature difference between day and night in summer entering the ring network box. On the other hand, it does not require frequent manual operation, thereby improving its practicality.

[0062] like Figure 8 and Fig. 9As shown, a replenishment assembly 70 is provided at the rear end of the box body 10, and the replenishment assembly 70 includes a water reservoir 71 fixedly connected to the rear end of the box body 10, a filter screen 72 is movably connected to the top of the water reservoir 71, a water pipe 73 is fixedly connected between the bottom of the water reservoir 71 and the water tank 51, and a one-way valve is provided inside the water pipe 73, which on the one hand ensures the stability of the air pressure inside the water tank 51, and on the other hand prevents the water inside the water tank 51 from flowing back into the water reservoir 71; the water tank 51 is C-shaped to wrap around the cabinet body 90, and the distance that the drainage eaves 80 extends out of the box body 10 is less than the width of the water reservoir 71, so that rainwater falling on the drainage eaves 80 can be collected in the water reservoir 71, which speeds up the collection of rainwater and improves the replenishment efficiency.

[0063] Specifically, a water tank 51 is arranged inside the box 10, and its fundamental purpose is to spray atomized water into the air during cooling to improve the cooling effect. On this basis, the volume of the water tank 51 is increased to span the entire inner width of the box 10. The increase in the volume of the water tank 51 ensures that there is enough water for auxiliary heat dissipation, and also reduces the frequency of water replenishment. At the same time, the water tank 51 with a large water body is arranged in a C shape to wrap the cabinet 90 to play a role in heat preservation. The physical property of high specific heat capacity of water is used to reduce the maximum and minimum temperature values ​​inside the box 10 in summer and winter, and cooperate with the work of the heat dissipation fan 32 to further improve the heat dissipation effect inside the box 10;

[0064] In addition, in view of the large amount of precipitation in summer, the water reservoir 71 can be used to collect rainwater and flow it into the water tank 51 through the water pipe 73 to replenish the water tank 51, while the filter 72 can intercept impurities in the rainwater to prevent the impurities from entering the water tank 51 and clogging the atomizing nozzle 53 when being discharged from the atomizing nozzle 53. The replenishment through rainfall ensures that the water source inside the water tank 51 is sufficient, ensuring that the cooling component 50 can work stably for a long time, and ensuring the sustainability of the cooling while ensuring the cooling effect.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
