Description

[0001] The present invention relates to the technical field of integrated distribution boxes, and in particular to a portable low-voltage integrated distribution box for intelligent devices. Background Art

[0002] The distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, relatively common application, stable and reliable operation, high space utilization, small footprint and environmental protection effect;

[0003] However, the current distribution box lacks corresponding auxiliary cooling and sealing components during use, which makes it impossible for the distribution box to effectively balance the sealing and heat dissipation performance inside the box. As a result, when the distribution box has good heat dissipation performance, it cannot effectively prevent external dust from entering the box, causing dust to accumulate inside the distribution box. When the interior of the distribution box is fully sealed, the heat dissipation performance inside the distribution box will decrease, causing various components inside the distribution box to malfunction due to excessive temperature, thereby reducing the overall convenience of use of the distribution box.

[0025] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0026] 1. An internal and external circulation sealed cooling mechanism is set up. Through the mutual cooperation between the internal components of the internal and external circulation sealed cooling mechanism, the cooling sealing process inside the distribution box is optimized. Through the continuous exchange of coolant between the cooling top box and the heat dissipation top box, the heat inside the distribution box is continuously transported outward through the coolant, and the cooling fan blades are actively driven to rotate during the circulation of the coolant to form a continuously flowing heat dissipation airflow on the top of the heat dissipation top box, thereby effectively improving the overall heat dissipation efficiency of the distribution box. At the same time, the lifting liquid capsule and the telescopic rubber net are effectively increased through the multi-section tortuous outer surface structure design on the outside. The contact area of ​​the hot air flow inside the electrical box body is increased, so that the coolant inside the lifting liquid bag can fully exchange heat with the hot air flow inside the distribution box body, and the heat inside the distribution box body is absorbed and gathered through the telescopic rubber net, thereby effectively optimizing the heat dissipation process inside the distribution box, so that the heat inside the distribution box body can be quickly gathered to the edge of the distribution box body, ensuring that the temperature of the working area of ​​the electrical components can be continuously maintained in the appropriate temperature range, further improving the heat dissipation effect inside the distribution box, effectively avoiding the failure of the electrical components inside the distribution box due to excessive temperature, and effectively improving the service life of the distribution box;

[0027] At the same time, the coolant inside the cooling top box can be introduced into the sealing rubber ring and the front sealing liquid bag through the sealing liquid pump, thereby realizing the sealing of the cable connection hole on the back of the distribution box body, and the front sealing liquid bag is used to seal the distribution box body and the distribution box door, thereby effectively improving the overall sealing of the distribution box, effectively avoiding the phenomenon of dust accumulation inside the distribution box after long-term use, thereby improving the cleanliness inside the distribution box, preventing the phenomenon of heat dissipation efficiency decreasing due to excessive dust accumulation inside the distribution box, and further improving the use stability of the distribution box;

[0028] In addition, during the process of exchanging the coolant inside and outside the cooling top box, the lifting liquid bag will naturally shrink, thereby increasing the idle cavity inside the distribution box body, and then reducing the pressure inside the distribution box body, so that the distribution box door fits more closely with the distribution box body under the action of pressure. While the pressure inside the distribution box body changes, the sealing liquid pump can also drive the sealing ring and the coolant inside the front sealing liquid bag to exchange with the cooling top box, thereby realizing the exchange of heat at the corners of the distribution box body. While the sealing ring and the front sealing liquid bag shrink, the inside of the distribution box body is still in a low pressure state. Therefore, when cooling the corners inside the distribution box body, the overall sealing of the distribution box can also be guaranteed, and the uniformity of temperature distribution inside the distribution box is effectively improved.

[0029] 2. A bottom semi-sunken protection mechanism is provided. The overall protection process of the distribution box is optimized through the mutual cooperation between the internal components of the bottom semi-sunken protection mechanism. Through the mutual cooperation between the supporting liquid bag and the flexible telescopic side bag inside the sinking bottom box, the distribution box body is flexibly limited by the relaxed reeled cable and the supporting liquid bag after half-sunk into the sinking bottom box, and the outer side of the distribution box body is protected by the flexible telescopic side bag, so that the distribution box body can be buffered by the supporting liquid bag when it is subjected to external vibration, effectively preventing the distribution box body from transmitting external vibration to the electrical components and causing damage to the electrical components, thereby effectively improving the anti-interference ability of the distribution box. At the same time, the flexible telescopic side bag can also be used to form a flexible protection on the outer side of the distribution box body to prevent external impact from directly acting on the outer side of the distribution box body, further improving the safety of the distribution box.

[0030] At the same time, the coolant is evenly sprayed and attached to the outside of the flexible telescopic side bag through the pressurized diverter pump, the liquid distributing top box and the pressure relief valve to form a coolant film, thereby effectively preventing external fire sources from directly burning the distribution box body, effectively improving the fire resistance of the distribution box, and effectively increasing the isolation between the inside and outside of the distribution box. When a single distribution box catches fire due to a fault, the inside and outside of the distribution box can also be isolated by the flexible telescopic side bag, which can effectively avoid the spread of the distribution box’s own fault fire to the outside, and can also effectively prevent external fire sources from affecting the inside of the distribution box, thereby effectively improving the safety of the distribution box.

[0031] To summarize, through the mutual cooperation between the internal and external circulation sealed cooling mechanism and the internal components of the bottom semi-sunken protection mechanism, and through the circulation exchange of coolant inside and outside the cooling top box and the heat dissipation top box, efficient cooling of the inside of the distribution box body is achieved, and the distribution box is effectively prevented from malfunctioning due to excessive internal temperature. At the same time, through the mutual cooperation of the coolant inside the supporting liquid bag and the flexible telescopic side bag, the distribution box body is isolated and protected, and external impact and vibration are effectively prevented from causing damage to the internal components of the distribution box. By actively forming a cooling liquid film in the flexible telescopic side bag, the overall fire resistance of the distribution box is effectively improved, thereby effectively improving the safety of use and environmental suitability of the distribution box.

[0054] A cooling circulation pump 418 is embedded in the middle of the top of the cooling top box 401. The cooling circulation pump 418 is powered by an external power supply. A circulating heat pipe 419 is fixedly connected to the middle of the top of the cooling circulation pump 418. A heat dissipation top box 420 is fixedly connected to the end of the circulating heat pipe 419 corresponding to the top position of the cooling top box 401.

[0057] In addition, during the process of exchanging the coolant inside the cooling top box 401 with the coolant inside, the lifting liquid capsule 402 will naturally shrink, thereby increasing the idle cavity inside the distribution box body 1, thereby reducing the pressure inside the distribution box body 1, so that the distribution box door 2 fits more closely with the distribution box body 1 under the action of pressure. While the pressure inside the distribution box body 1 changes, the sealing liquid pump 408 can also drive the coolant inside the sealing rubber ring 413 and the sealing front liquid capsule 415 to exchange with the cooling top box 401, thereby realizing the exchange of heat at the corners of the distribution box body 1. While the sealing rubber ring 413 and the sealing front liquid capsule 415 shrink, the inside of the distribution box body 1 is still in a low-pressure state. Therefore, when cooling the corners inside the distribution box body 1, the overall sealing of the distribution box can be guaranteed, and the uniformity of the temperature distribution inside the distribution box is effectively improved.

The overall protection process of the distribution box is optimized through the mutual cooperation between the internal components of the bottom semi-sunken protection mechanism 5, and the distribution box is made After the main body 1 is half-sunk into the sinking bottom box 501, the main body 1 of the distribution box is flexibly limited by the relaxed reeled cable 507 and the supporting liquid capsule 511, and the outer side of the main body 1 of the distribution box is protected by the flexible telescopic side capsule 521, so that when the main body 1 of the distribution box is subjected to external vibration, it can be buffered by the supporting liquid capsule 511, effectively preventing the main body 1 of the distribution box from transmitting external vibration to the electrical components 3 and causing damage to the electrical components 3, thereby effectively improving the anti-interference ability of the distribution box, and at the same time, the flexible telescopic side capsule 521 can also be used to form a flexible protection on the outer side of the main body 1 of the distribution box to prevent external impact from directly acting on the outer side of the main body 1 of the distribution box, further improving the safety of the use of the distribution box;

[0064] At the same time, the pressurized shunt pump 516 cooperates with the liquid separation top box 522 and the pressure relief valve 524 to evenly spray the coolant onto the outside of the flexible telescopic side bag 521 to form a coolant film, thereby effectively preventing external fire sources from directly burning the distribution box body, effectively improving the fire resistance of the distribution box, and effectively increasing the isolation between the inside and outside of the distribution box. When a single distribution box catches fire due to a fault, the flexible telescopic side bag 521 can also be used to isolate the inside and outside of the distribution box, which can effectively avoid the spread of the distribution box's own fault fire to the outside, and can also effectively prevent external fire sources from affecting the inside of the distribution box, thereby effectively improving the safety of the distribution box.

[0065] Working principle and use process of the present invention: In the process of long-term use of the distribution box main body 1, the distribution box main body 1 can be sealed through the distribution box door 2. At the same time, the electrical components 3 continue to generate heat during long-term use, and the inside of the distribution box main body 1 needs to be continuously cooled and dissipated. The cooling liquid inside the distribution box main body 1 is centrally stored through the cooling top box 401. When it is necessary to seal and protect the distribution box main body 1 and the distribution box door 2, the cooling liquid inside the cooling top box 401 is introduced into the infusion top pipe 410 through the sealing liquid pump 408 and the collecting side pipe 409, and then the cooling liquid is introduced into the sealing connecting valve 411 through the infusion top pipe 410, and the cooling liquid is respectively introduced into the shunt back pipe 412 and the shunt front pipe 412 through the sealing connecting valve 411. 14, the coolant is introduced into the sealing rubber ring 413 through the shunt back pipe 412, so that the pressure inside the sealing rubber ring 413 increases and expands, so that the cable connection hole on the distribution box body 1 is filled and sealed through the expansion of the sealing rubber ring 413, and then the coolant is introduced into the front sealing liquid capsule 415 through the shunt front pipe 414, and the pressure inside the front sealing liquid capsule 415 increases and expands, so that the front sealing liquid capsule 415 can be tightly fitted with the limiting outer frame 416 and the connecting side plate 417 after expansion, thereby realizing the sealing of the gap between the distribution box body 1 and the distribution box door 2, effectively preventing the external dust from entering the distribution box body 1 due to insufficient sealing during use, and effectively improving the overall sealing of the distribution box;

[0066] After the inside of the distribution box body 1 is sealed, when the inside of the distribution box body 1 needs to be cooled, the cooling liquid in the cooling top box 401 is driven to be sucked through the cooling circulation pump 418, and the cooling liquid in the cooling top box 401 is transported upward to the inside of the heat dissipation top box 420 through the circulating heat pipe 419. At the same time, in the process of the cooling liquid in the circulating heat pipe 419 entering the inside of the heat dissipation top box 420, it will preferentially flow through the inside of the material guide square tube 421, and then the cooling liquid is introduced into the inside of the distribution cross pipe 426 at the end through the material guide square tube 421, and the high-temperature cooling liquid is evenly diffused into the inside of the heat dissipation top box 420 through the discharge port on the side of the distribution cross pipe 426. In the process of the high-temperature cooling liquid flowing through the internal cavity of the heat dissipation top box 420, the heat dissipation fins 427 can accelerate the heat of the high-temperature cooling liquid in the heat dissipation top box 420 to diffuse to the surroundings;

[0067] In addition, when the coolant flows through the driving round box 422 through the guide square tube 421, the cooling fan blade 425 can be driven to rotate by the flowing driving blade 423, and a continuous flow of air will be generated at the top of the heat dissipation top box 420 during the rotation of the cooling fan blade 425. When these airflows flow along the outer sides of the heat dissipation fins 427, the heat will be taken away from the heat dissipation fins 427, so as to cool the high-temperature coolant in the heat dissipation top box 420. Finally, the cooled coolant is guided back to the cooling top box 401 through the return side pipe 429, thereby realizing the circulation of the coolant.

[0068] After the coolant in the cooling top box 401 quickly enters the heat dissipation top box 420, the total amount of coolant in the cooling top box 401 decreases and the pressure drops, thereby driving the connecting bottom box 403 to move upward through the elastic contraction of the contraction spring 407, and driving the lifting liquid bag 402 to contract during the movement of the connecting bottom box 403. At the same time, during the upward movement of the connecting bottom box 403, the telescopic rubber net 405 is elastically extended along the top of the fixed side plate 404, and the ratio of the coolant in the cooling top box 401 and the heat dissipation top box 420 is alternately adjusted to achieve telescopic The rubber net 405 rapidly and alternately expands and contracts, and the airflow inside the distribution box body 1 is driven to circulate internally through the alternate expansion and contraction of the expansion and contraction rubber net 405. At the same time, as the lifting liquid capsule 402 and the connecting bottom box 403 expand and contract, the cavity volume inside the distribution box body 1 is dynamically adjusted, thereby causing the pressure inside the distribution box body 1 to change periodically. Then, the sealing liquid pump 408 periodically rotates forward and reversely to drive the sealing rubber ring 413 and the sealing front liquid capsule 415 to exchange coolant with the inside of the cooling top box 401, thereby realizing heat exchange at the corners inside the distribution box body 1.

[0069] When the distribution box needs to be protected in case of emergencies such as fire or earthquake, an additional storage space is set at the bottom of the distribution box body 1 by sinking the bottom box 501, and a relatively independent sealed cavity is formed at the bottom of the lifting bottom plate 502 by connecting the bottom frame 510, the supporting liquid capsule 511 and the installing bottom box 512. The bottom of the lifting bottom plate 502 is supported by the coolant inside the supporting liquid capsule 511 and the supporting spring 513, and the corners of the lifting bottom plate 502 are pulled and limited by the winding cable 507, thereby ensuring that the distribution box body 1 can be stably placed on the top of the lifting bottom plate 502 during normal use, so as to ensure the normal use of the distribution box body 1;

[0070] When an emergency occurs and the distribution box needs to be stored and protected, the winding motor 504 is started to reverse and drive the driving horizontal shaft 505 and the winding roller 506 to rotate, and the winding cable 507 is paid out during the rotation of the driving horizontal shaft 505 and the winding roller 506 to release the constraint of the winding cable 507 on the lifting base plate 502, and then the pressurized shunt pump 516 installed on the top of the inner frame 514 is started to transport and guide the coolant inside the supporting liquid capsule 511, and the coolant is introduced into the shunt bottom box 518 through the pressurized shunt pump 516, and then the coolant is introduced into the shunt pipe 519 through the shunt bottom box 518, and then the coolant inside the shunt bottom box 518 is introduced into the connecting side box 520 through the shunt pipe 519, so that the coolant inside the supporting liquid capsule 511 can be transferred to the flexible telescopic side capsule 521. As the coolant inside the flexible telescopic side capsule 521 continues to increase, the flexible telescopic side capsule 521 continuously brings the liquid separator top box 522 and its internal components to rise synchronously along the outer side of the distribution box body 1, and after the flexible telescopic side bag 521 rises to the highest point, a flexible protective layer is formed on the outer side of the distribution box body 1 through the flexible telescopic side bag 521 to prevent external impact from directly hitting the outer side of the distribution box body 1 and causing damage to the distribution box body 1. When a fire occurs on the outer side of the distribution box body 1, the pressurized shunt pump 516 continuously pressurizes the inside of the flexible telescopic side bag 521. When the internal pressure of the flexible telescopic side bag 521 exceeds the predetermined value of the pressure relief valve 524, the coolant inside the flexible telescopic side bag 521 can pass through the isolation inner plate 523 into the upper space inside the liquid separator top box 522, and the coolant is discharged through the drainage hole on the top of the liquid separator top box 522, and then a layer of coolant film is formed on the outer side of the flexible telescopic side bag 521 through the coolant, so as to realize the protection of the outer side of the distribution box body 1.

[0071] When it is necessary to reset the distribution box after sinking, the pressurized shunt pump 516 is started and reversed to reintroduce the coolant inside the flexible telescopic side bag 521 into the supporting liquid bag 511, and the winding motor 504 is started at the same time to drive the driving horizontal axis 505 and the winding roller 506 to rotate, and the winding cable 507 is wound during the rotation of the winding roller 506, and then the lifting base plate 502 is driven to rise again by the winding of the winding cable 507, so as to realize the reset of the distribution box body 1.
