Description

Technical Field

[0001] The present invention relates to the technical field of box-type substations, and in particular to a box-type substation with a heat dissipation structure. Background Art

[0002] A box-type substation is a substation that organically combines high-voltage power receiving, transformer step-down, and low-voltage power distribution functions and is installed in a fully enclosed, movable steel structure box. It has a series of advantages, such as strong completeness, short power transmission cycle, strong environmental adaptability, easy installation, safe and reliable operation, low investment and quick results. With the acceleration of the modernization process of municipal construction, box-type substations have been widely used in public power distribution in urban network construction and transformation, and have gradually replaced the original civil power distribution room, becoming a new type of complete power distribution device.

[0003] Existing box-type substations have heat dissipation mechanisms installed on the top of the box, and although they are equipped with rain shielding devices, the heat dissipation holes are designed to be directly open. When encountering strong winds, even with rain shielding measures, rainwater will still be blown into the heat dissipation holes by the strong wind and then flow into the interior of the box-type substation. This will not only cause short circuits in electrical equipment inside the box-type substation, degrade insulation performance, and even cause fires, but also, after entering the box-type substation, rainwater will accumulate on the surface of the equipment and the bottom of the box, increasing maintenance difficulty and cost.

[0004] Secondly, the heat dissipation direction of the directly opened heat dissipation holes will be restricted by the rain shielding mechanism, and the heat will accumulate on the top of the box-type substation, forming a heat island effect, which will further affect the heat dissipation effect, causing the operating environment of the box-type substation to deteriorate and increase the risk of failure of the box-type substation during operation.

[0019] (3) Beneficial effects

[0020] Compared with the prior art, the present invention provides a box-type substation with a heat dissipation structure, which has the following beneficial effects:

[0021] 1. The waterproof heat dissipation mechanism can discharge high-temperature air from the heat dissipation channel, connecting groove and exhaust hole. When rainwater enters the exhaust hole, it will only remain inside the exhaust hole and will not enter the heat dissipation window and the box-type substation body below through the connecting groove and heat dissipation channel. This not only effectively prevents rainwater from damaging the electrical equipment inside the box-type substation body, but also significantly reduces the risk of equipment short circuit and fire, ensures the dryness and stability of the operating environment of the box-type substation body, thereby improving the safety and reliability of the box-type substation body, reducing the box-type substation body failures and safety accidents caused by rainwater, ensuring the stability and safety of power supply, and reducing water accumulation at the bottom of the box-type substation body, reducing the corrosion and aging speed of the internal electrical equipment, thereby reducing the maintenance workload and maintenance frequency, extending the service life of the box-type substation body, reducing the frequency of replacement of its internal electrical equipment, and further reducing the overall operating cost;

[0022] Among them, through the set drainage holes and drainage channels, when there is water accumulation inside the exhaust hole, rainwater can be automatically discharged from the heat dissipation window, effectively preventing the formation of water accumulation, reducing the water accumulation inside the exhaust hole, and reducing the occurrence of rainwater entering the box-type substation body through the heat dissipation window. Moreover, through the automatic drainage function, the accumulation of water is reduced, and the maintenance frequency and workload of the heat dissipation window by the staff are reduced.

[0023] 2. The height of the drainage plate can be adjusted by setting the hollow column, piston rod, fixed block, connecting plate, lifting frame, lifting column, fixed plate and lifting plate, so that the opening of the connecting groove can be narrowed in heavy rain weather, which can not only effectively reduce the possibility of rainwater entering the heat dissipation holes, thereby significantly reducing the risk of rainwater damaging the internal equipment of the box-type substation body and improving the operational safety of the equipment, but also can flexibly adjust the heat dissipation effect according to different weather conditions. In high temperature weather, the opening of the connecting groove can be increased to improve the heat dissipation effect. In heavy rain weather, the opening of the connecting groove can be narrowed to prevent rainwater from entering.

[0024] 3. The heat dissipation direction conversion mechanism can drive the fan blades on both sides to swing back and forth, forming an airflow and blowing away the hot air emitted from the top of the box-type substation body, thereby breaking the heat island effect and significantly improving the heat dissipation effect, so that the box-type substation body can operate stably in a high temperature environment, ensuring the stability of the operating environment of the box-type substation body, reducing the downtime of the box-type substation body caused by high temperature, and improving the operating stability and reliability of the box-type substation body.

[0025] 4. Through the support frame and button, when the internal temperature of the box-type substation body drops to the set value, the drive motor can be automatically shut down and the rotation of the fan blades can be stopped. This automatic control mechanism can accurately adjust the operating status of the fan blades according to the actual heat dissipation needs, effectively avoiding unnecessary energy consumption, thereby significantly reducing operating costs. At the same time, by automatically shutting down the drive motor, the operating time of the shaft and fan blades is reduced, the wear of mechanical parts is reduced, and the service life of the cooling fan and drive motor is extended.

[0038] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] This embodiment is a box-type substation with a heat dissipation structure, such as Figure 1 - Figure 8As shown, it includes a box-type substation body 1, a rain shield 3 is provided above the box-type substation body 1, and support columns 2 are fixedly connected at the four corners of the lower end surface of the rain shield 3, and the support columns 2 are fixedly connected to the upper end surface of the box-type substation body 1. It also includes a waterproof heat dissipation mechanism and a heat dissipation direction changing mechanism. The waterproof heat dissipation mechanism includes symmetrically arranged heat dissipation windows 401, and the heat dissipation windows 401 are all connected to the box-type substation body 1. Exhaust fans 404 are fixedly connected inside the heat dissipation windows 401, and lifting frames 403 are provided above the heat dissipation windows 401. Exhaust holes 402 are equidistantly provided on the upper end surface of the heat dissipation windows 401, and heat dissipation channels 406 are equidistantly provided on the top of the heat dissipation windows 401. The exhaust holes 402 and the heat dissipation channels 406 are staggered with each other, and the exhaust holes 402 and the heat dissipation channels 406 are connected by connecting grooves 410. The waterproof heat dissipation mechanism is used to prevent rainwater from entering the interior of the box-type substation body 1 through the exhaust holes 402 and the heat dissipation windows 401.

[0040] In this embodiment, Figure 5 As shown, arc-shaped drainage grooves 409 are opened at the top of the heat dissipation channel 406, and lifting plates 412 are provided under the connecting grooves 410. The lifting plates 412 are all slidably connected to the heat dissipation window 401. The upper ends of the lifting plates 412 are fixedly connected with drainage plates 411. The drainage plates 411 and the arc-shaped drainage grooves 409 work together. When hot air enters the heat dissipation channel 406, it will flow into the exhaust hole 402 for discharge through the influence of the arc-shaped drainage grooves 409, the drainage plates 411 and the connecting grooves 410.

[0041] In this embodiment, Figure 8 As shown, drainage holes 419 are opened on both sides of the exhaust hole 402, and drainage channels 405 are opened symmetrically inside the heat dissipation window 401. The drainage holes 419 on the same side are connected to the drainage channels 405 on the same side. When water accumulates inside the exhaust hole 402, it will flow into the drainage channel 405 together with the drainage holes 419, and finally flow out through the drainage channel 405.

[0042] In this embodiment, Figure 7 As shown, a fixing plate 418 is fixedly connected between two adjacent lifting plates 412, and the upper end surfaces of the fixing plates 418 are fixedly connected to the lifting columns 417. The lifting columns 417 are all slidably connected to the heat dissipation window 401. A horizontal plate 416 is fixedly connected between the upper ends of the lifting columns 417 on the same side, and the horizontal plates 416 are fixedly connected to the lower end surfaces of the lifting frames 403. When the lifting frames 403 move up and down, the lifting plates 412 can be driven to rise and fall synchronously through the provided horizontal plates 416, lifting columns 417 and fixing plates 418.

[0043] In this embodiment, Figure 6As shown, a connecting plate 415 is rotatably connected to the center of the lower end surface of the lifting frame 403, and a fixed block 414 is rotatably connected to the end of the connecting plate 415 away from the lifting frame 403. A piston rod 413 is passed through and fixedly connected to the fixed block 414. Hollow columns 408 are sleeved on both ends of the piston rod 413. The ends of the hollow columns 408 away from the piston rod 413 are fixedly connected to a support plate 407. The support plates 407 are fixedly connected to the upper end surface of the heat dissipation window 401. Ethanol is stored in one of the hollow columns 408. When the ethanol in the hollow column 408 is exposed to high or low temperatures, it will expand and contract, pushing the piston rod 413 to slide into the other hollow column 408, squeezing the air in the other hollow column 408. The squeezed air will push back, driving the fixed block 414 connected to the outer surface of the piston rod 413 to move horizontally, and the fixed block 414, affected by the connecting plate 415, will pull the lifting frame 403 to move up and down.

[0044] In the prior art, although the heat dissipation mechanism set on the top of the box-type substation is equipped with a rain shielding device, since the heat dissipation holes are of a straight-open design, when encountering strong winds, even with rain shielding measures, rainwater will still be blown into the heat dissipation holes by the strong wind, and then flow into the interior of the box-type substation, which will not only cause short circuits in the electrical equipment inside the box-type substation, degradation of insulation performance, and even cause fires, but also, after the rainwater enters the interior of the box-type substation, it will accumulate on the surface of the equipment and the bottom of the box, increasing the difficulty of maintenance and increasing the maintenance cost. Compared with the prior art, the high-temperature air can be discharged from the heat dissipation channel 406, the connecting groove 410 and the exhaust hole 402, and when the rainwater enters the exhaust hole 402, it will only remain inside the exhaust hole 402 and will not pass through the connecting groove 410 and the heat dissipation channel 406. The heat channel 406 enters the heat dissipation window 401 and the interior of the box-type substation body 1 below, which not only effectively prevents rainwater from damaging the electrical equipment inside the box-type substation body 1, significantly reduces the risk of equipment short circuit and fire, and ensures the dryness and stability of the operating environment of the box-type substation body 1, thereby improving the safety and reliability of the operation of the box-type substation body 1, reducing the failures and safety accidents of the box-type substation body 1 caused by rainwater, ensuring the stability and safety of the power supply, but also reduces the accumulation of water at the bottom of the box-type substation body 1, reduces the corrosion and aging speed of the internal electrical equipment, thereby reducing the maintenance workload and maintenance frequency, extending the service life of the box-type substation body 1, reducing the frequency of replacement of its internal electrical equipment, and further reducing the overall operating cost;

[0045] Among them, through the set drainage holes 419 and drainage channels 405, when there is water accumulation inside the exhaust hole 402, rainwater can be automatically discharged from the heat dissipation window 401, effectively preventing the formation of water accumulation, reducing the water accumulation inside the exhaust hole 402, and reducing the occurrence of rainwater entering the box-type substation body 1 through the heat dissipation window 401. In addition, through the automatic drainage function, the accumulation of water is reduced, and the maintenance frequency and workload of the staff on the heat dissipation window 401 are reduced.

[0046] In other aspects, this embodiment also provides a heat dissipation direction conversion mechanism for discharging the hot air discharged from the heat dissipation window 401 from the inside of the rain shield 3, such as Figure 2 and Figure 3 As shown, the heat dissipation direction changing mechanism includes a rotating shaft 501, which is rotatably connected to the center of the upper end surface of the box-type substation body 1, and the rotating shaft 501 is located between the two heat dissipation windows 401. The outer surface of the rotating shaft 501 is symmetrically fixedly connected with fan blades 502.

[0047] In this embodiment, Figure 3 As shown, the outer surface of the rotating shaft 501 is fixedly connected to a sector gear 505, and one side of the sector gear 505 is meshed with a rack plate 506, and the rack plate 506 is fixedly connected to the side away from the sector gear 505 with a linkage plate 507, and the lower end surface of the linkage plate 507 is symmetrically fixedly connected to a slide plate 508, and slide rails 509 are provided under the slide rails 508. The slide rails 509 are all fixedly connected to the upper end surface of the box-type substation body 1, and the slide rails 508 are all slidably connected to the slide rails 509. When the linkage plate 507 is slidably connected to the slide rails 509 through the slide plate 508 and the slide rails 509 for horizontal reciprocating movement, it will drive the rack plate 506 to move synchronously. At the same time, through the meshing connection between the rack plate 506 and the sector gear 505, the rotating shaft 501 is driven to rotate back and forth left and right.

[0048] In this embodiment, Figure 3 As shown, a through slot 510 is provided on the linkage plate 507, and a shift rod 511 is slidably connected inside the through slot 510. The lower end of the shift rod 511 is fixedly connected to a shift plate 512, and the lower end surface of the shift plate 512 is fixedly connected to the side away from the shift rod 511. The lower end of the drive shaft 513 is fixedly connected to a drive motor 514, and the drive motor 514 is fixedly connected to the upper end surface of the box-type substation body 1. When the drive motor 514 drives the drive shaft 513 to rotate, the shift rod 511 is driven to move by the set shift plate 512, so that the shift rod 511 slides back and forth on the through slot 510. At the same time, the shift rod 511 synchronously drives the linkage plate 507 to move through the through slot 510 during the movement.

[0049] In this embodiment, Figure 2 and Figure 3As shown, the drive motor 514 is electrically connected to the button 504, and the upper end of the button 504 is fixedly connected to the support frame 503, and the support frame 503 is fixedly connected to the upper end surface of one of the heat dissipation windows 401. The button 504 is located above the lifting frame 403. When the lifting frame 403 rises, the button 504 will be pressed, and the operation of the drive motor 514 will be turned off through the electrical connection between the button 504 and the drive motor 514. Conversely, when the lifting frame 403 and the button 504 are separated, the drive motor 514 will be automatically turned on to work.

[0050] In the prior art, the heat dissipation direction of the straight-open heat dissipation holes will be restricted by the rain shielding mechanism, and the heat will accumulate at the top of the box-type substation, forming a heat island effect, which will further affect the heat dissipation effect, causing the operating environment of the box-type substation to deteriorate and increase the risk of failure of the box-type substation during operation. Compared with the prior art, the fan blades 502 on both sides can be driven to swing back and forth to form airflow, and blow away the hot air dissipated from the top of the box-type substation body 1, thereby breaking the heat island effect and significantly improving the heat dissipation effect, so that the box-type substation body 1 can operate stably in a high temperature environment, ensuring the stability of the operating environment of the box-type substation body 1, reducing the downtime of the box-type substation body 1 caused by high temperature, and improving the operating stability and reliability of the box-type substation body 1.

[0051] The working process and principles involved in the overall content of the above embodiment are as follows:

[0052] When the box-type substation body 1 is working, the exhaust fan 404 installed inside the heat dissipation window 401 will exhaust the high-temperature air inside the box-type substation body 1. When the high-temperature air enters the heat dissipation window 401, it will first enter the heat dissipation channel 406 opened at the top of the heat dissipation window 401, and then, under the influence of the arc-shaped drainage groove 409 opened at the top of the heat dissipation channel 406, the high-temperature air will be guided to the connecting grooves 410 on both sides. When the high-temperature air enters the connecting groove 410, it will be affected by the bottom of the connecting groove 410. The high-temperature air is guided by the guide plate 411 and then guided into the connecting groove 410 again, and then transported into the exhaust hole 402 and discharged through the exhaust hole 402 again. When the high-temperature air discharged from the exhaust hole 402 is too high, it will contact the hollow column 408 above the heat dissipation window 401. At this time, the ethanol inside the hollow column 408 will expand due to the high temperature, and the piston rod 413 will slide out from one of the hollow columns 408 and slide into the other hollow column 408, while the other hollow column 408 will be expanded. The air inside 408 is squeezed, and during the horizontal movement of the piston rod 413, the piston rod 413 drives the fixed block 414 connected to the outer surface to move horizontally away from the lifting frame 403. Since the upper end of the fixed block 414 is rotatably connected to the connecting plate 415, the end of the connecting plate 415 away from the fixed block 414 is rotatably connected to the lower end surface of the lifting frame 403, and the lower end surface of the lifting frame 403 is symmetrically fixedly connected to the cross plate 416, and the lower end surface of the cross plate 416 is equidistantly fixedly connected to the lifting column 417, so as the fixed block 41 4 moves horizontally away from the lifting frame 403, and through the provided connecting plate 415, it can pull the lifting frame 403 downward vertically, and push the horizontal plate 416 to drive the lifting column 417 to slide downward into the heat dissipation window 401, and push the fixed plate 418 connected to the lower end of the lifting column 417 to drive the lifting plates 412 on both sides to slide into the heat dissipation window 401, and pull the guide plate 411 connected to the upper end of the lifting plate 412 away from the arc-shaped guide groove 409, thereby increasing the opening of the connecting groove 410 and improving the heat dissipation effect in hot weather;

[0053] When heavy rain comes, the hollow columns 408 will come into contact with the surrounding cold air. At this time, the ethanol inside one of the hollow columns 408 will shrink, and the squeezed air inside the other hollow column 408 will rebound, pushing the piston rod 413 to slide again into the hollow column 408 containing ethanol, driving the fixed block 414 connected to the outer surface of the piston rod 413 to move closer to the lifting frame 403. As the fixed block 414 moves horizontally in the opposite direction, the connecting plate 415 can push the lifting frame 403 to rise. During the rising process, the lifting frame 403 pushes the diversion plate 411 again close to the arc-shaped diversion groove 409 through the cross plate 416, the lifting column 417, the fixed plate 418 and the lifting plate 412, thereby reducing the opening of the connecting groove 410 in heavy rain, effectively reducing the possibility of rainwater entering the heat dissipation hole, thereby significantly reducing the risk of rainwater damaging the internal equipment of the box-type substation body 1, improving the operating safety of the equipment, and preventing rainwater from entering;

[0054] At this time, when rainwater enters the exhaust hole 402 under the influence of the storm, it is unable to directly enter the heat dissipation channel 406 through the connecting groove 410 due to the influence of the inclination angle of the lifting plate 412 and the connecting groove 410, and then enter the box-type substation body 1 through the heat dissipation window 401, so that the rainwater will only remain in the exhaust hole 402, and will not enter the heat dissipation window 401 and the box-type substation body 1 below through the connecting groove 410 and the heat dissipation channel 406, which not only effectively prevents the damage of rainwater to the electrical equipment inside the box-type substation body 1, but also significantly reduces the risk of equipment short circuit and The risk of fire is reduced, and the operating environment of the box-type substation body 1 is ensured to be dry and stable, thereby improving the safety and reliability of the operation of the box-type substation body 1, reducing the failure and safety accidents of the box-type substation body 1 caused by rainwater, ensuring the stability and safety of the power supply, and reducing the accumulation of water at the bottom of the box-type substation body 1, reducing the corrosion and aging speed of the internal electrical equipment, thereby reducing the maintenance workload and maintenance frequency, extending the service life of the box-type substation body 1, reducing the frequency of replacement of its internal electrical equipment, and further reducing the overall operating cost;

[0055] When rainwater enters the exhaust hole 402, the rainwater will flow to both sides of the exhaust hole 402, through the drainage holes 419 opened on both sides of the exhaust hole 402, and into the drainage channel 405 opened on the heat dissipation window 401, and finally be discharged from the inside of the drainage channel 405, thereby effectively preventing the formation of water accumulation, reducing the accumulation of water inside the exhaust hole 402, and reducing the occurrence of rainwater entering the box-type substation body 1 through the heat dissipation window 401. In addition, the automatic drainage function reduces the accumulation of water, and reduces the maintenance frequency and workload of the heat dissipation window 401 for the staff.

[0056] When the lifting frame 403 is lifted, the lifting frame 403 will contact the button 504 provided on the upper side and press the button 504. Since the button 504 is electrically connected to the driving motor 514, when the button 504 is pressed, the driving motor 514 will be turned off. On the contrary, when the lifting frame 403 and the button 504 are separated, the driving motor 514 is in the working state. During the working process of the driving motor 514, the driving motor 514 will drive the driving shaft 513 connected to the output end to rotate, and drive the lever 511 to move synchronously with the driving shaft 513 as the center through the dial plate 512 connected to the upper end of the driving shaft 513. With the movement of the dial rod 511, the dial rod 511 will slide back and forth in the through groove 510 provided on the linkage plate 507, and dial the linkage plate 507 through the through groove 510, driving the slide plate 508 connected to the lower end of the linkage plate 507 to move back and forth horizontally in the slide rail 509, so that the linkage plate 507 The gear 505 is meshed with the gear 506 and the gear 507 is meshed with the gear 506, and the gear 505 is meshed with the gear 506. The gear 505 is fixed to the outer surface of the shaft 501. Therefore, during the horizontal reciprocating movement of the linkage plate 507, the gear 506 is meshed with the gear 505, which can drive the shaft 501 to rotate synchronously left and right on the upper end surface of the box-type substation body 1, and drive the fan blades 502 symmetrically connected to the outer surface of the shaft 501 to swing back and forth, forming an airflow, and blowing the heat discharged by the heat dissipation window 401 away from between the box-type substation body 1 and the rain shield 3, thereby breaking the heat island effect and significantly improving the heat dissipation effect, so that the box-type substation body 1 can operate stably in a high temperature environment, ensuring the stability of the operating environment of the box-type substation body 1, reducing the downtime of the box-type substation body 1 caused by high temperature, and improving the operating stability and reliability of the box-type substation body 1.

[0057] When the lifting frame 403 is affected by the contraction of ethanol inside the hollow column 408 and rises, and the button 504 is pressed, the drive motor 514 is automatically turned off, and the rotation of the fan blades 502 is stopped. This automatic control mechanism can accurately adjust the operating state of the fan blades 502 according to the actual heat dissipation requirements, effectively avoid unnecessary energy consumption, and thus significantly reduce operating costs. At the same time, by automatically turning off the drive motor 514, the operating time of the rotating shaft 501 and the fan blades 502 is reduced, and the wear of mechanical parts is reduced, thereby extending the service life of the cooling fan and the drive motor 514.
