Description

Technical Field

[0001] This application relates to the technical field of box-type substations, and in particular to an outdoor box-type substation. Background Art

[0002] Outdoor box-type substations, as an indispensable part of the power industry, are widely used in various power scenarios due to their flexible combination, convenient transportation, rapid installation, short construction period, low operating cost, environmental protection and maintenance-free characteristics. Such substations usually consist of a sturdy box body and a box door, and the core electrical equipment such as high-voltage cabinets, low-voltage cabinets and transformers are carefully arranged inside. Through a clever wiring scheme, functions such as high-voltage power reception, transformer step-down, and low-voltage power distribution are seamlessly integrated and operated in a fully enclosed manner, ensuring the efficiency and safety of power supply.

[0003] However, in practical applications, outdoor box-type substations also face some technical challenges. Among them, the most prominent is the heat problem generated by the operation of electrical equipment inside the box body. Since these devices release a large amount of heat energy during continuous operation, the temperature inside the box body continues to rise, which may not only reduce the operating efficiency of other devices, but also cause damage to the devices themselves and shorten their service life.

[0004] To address this problem, traditional designs have opened heat dissipation openings on the box body in the hope of exhausting the internal hot air through natural convection. However, the effect of this heat dissipation method is often limited. Especially in hot summer or high-temperature environments, the heat dissipation capacity of the heat dissipation openings far cannot meet the heat dissipation requirements of the internal equipment. Once the temperature inside the box body exceeds the safety threshold, it may cause equipment failures and even more serious consequences.

[0005] Even more troublesome is that some outdoor box-type substations are deployed in remote or inaccessible areas. In these places, it is often difficult for staff to monitor the operating status of the substation in real time, resulting in problems such as abnormal internal temperature being difficult to detect and handle in a timely manner. This not only prolongs the maintenance cycle, but also may cause more serious damage due to the equipment being in a high-temperature state for a long time, posing a potential threat to the stable operation of the power system and there is room for improvement. Summary of the Invention

[0006] The purpose of this application is to provide an outdoor box-type substation to solve the problem in the above related technologies that when the box-type substation is applied outdoors and the internal hot air cannot be dissipated in time, the staff cannot discover it in time, which may affect the service performance of the internal electrical equipment.

[0007] An outdoor box-type substation provided by this application adopts the following technical solutions: An outdoor box-type substation, comprising a box body, a box cover fixedly arranged on the upper side of the box body, and a box door arranged on the vertical side surface of the box body; a diversion hole is opened in the upper part of the vertical side surface of the box body, a diversion fan is embedded on the inner wall of the diversion hole, a temperature sensor is fixedly arranged on the inner wall of the box body, and the temperature sensor controls the operation of the diversion fan according to the temperature inside the box body.

[0008] By adopting the above technical solution, during the operation of the box-type substation, due to the arrangement of the temperature sensor, the diversion fan and the diversion hole, the temperature sensor can be used to detect the temperature inside the box body and remotely feedback the real-time temperature inside the box body, and can automatically control the operation of the diversion fan according to the temperature inside the box body, thereby controlling the exchange and circulation of the internal and external gases of the box body through the diversion hole, and adjusting the heat dissipation performance of the box-type substation, reducing the problem that the internal electrical equipment is damaged due to overheating inside the box body.

[0009] Optionally, the box cover is larger than the cross-sectional dimension of the box body, a diversion inclined surface is arranged on the side surface of the box cover away from the box body, a confluence groove is opened around the edge of the side surface of the box cover away from the box body, the lowest side of the diversion inclined surface is flush with the bottom side of the confluence groove, and a diversion notch is opened on the bottom side of the confluence groove.

[0010] By adopting the above technical solution, when it rains outdoors, it can not only better protect the box body through the box cover, but also make the rainwater falling on the box cover slide down along the diversion inclined surface and pour into the confluence groove, and finally drain to the ground from the diversion notch, thereby avoiding the accumulation of rainwater on the box cover and improving the waterproof performance of the box body and the safety of outdoor use.

[0011] Optionally, a receiving plate for blocking the diversion notch is slidably arranged on the bottom side edge of the box cover, an adjusting member for controlling the up and down sliding of the receiving plate is arranged on the box body, and the state of the receiving plate sliding downwards is used for protecting the outer opening of the diversion hole.

[0012] By adopting the above technical solution, due to the arrangement of the receiving plate, on rainy days, the adjusting member can drive the receiving plate to slide downwards, and then contact the blocking of the diversion notch by the receiving plate, so that the rainwater can normally drain from the diversion notch. At the same time, the receiving plate in this state protects the outer opening of the diversion hole, reducing the possibility of rainwater entering the box body from the diversion hole; under normal conditions, the receiving plate resets to block the diversion notch.

[0013] Optionally, a lower protective cover with an opening downward is fixedly arranged on the outer opening edge of the diversion hole of the box body, a blocking plate is fixedly arranged on the bottom opening of the lower protective cover, and a plurality of blocking holes are opened on the blocking plate.

[0014] By adopting the above technical solution, the lower protective cover and the partition plate are used to protect the outer opening of the diversion hole, reducing the possibility of rainwater, dust, small flying insects or other impurities in the outside world entering the interior of the box through the diversion hole.

[0015] Optionally, a sealing plate is slidably arranged horizontally on the side of the partition plate away from the lower protective cover. A sealing hole coinciding with the blocking hole is formed in the sealing plate. The sealing plate can slide reciprocally in the direction close to the box body; a control rod is hinged to the bottom side edge of the receiving plate, and the other end of the control rod is hinged to the side edge of the sealing plate away from the box body; when the receiving plate slides downward, the control rod drives the sealing plate to slide in the direction close to the box body, so that the sealing hole and the blocking hole are misaligned.

[0016] By adopting the above technical solution, on a rainy day, the adjusting member drives the receiving plate to slide downward, and drives the sealing plate to slide in the direction close to the box body through the control rod, so that the sealing hole and the blocking hole are misaligned, thereby completely blocking the lower opening of the lower protective cover; when it is not raining, the adjusting member drives the receiving plate to slide upward, and drives the sealing plate to slide in the direction away from the box body through the control rod, so that the sealing hole and the blocking hole coincide, and the diversion hole can play a normal heat dissipation role.

[0017] Optionally, the adjusting member includes an adjusting rack, an adjusting gear and an adjusting motor. The adjusting rack is slidably arranged vertically on the outer side surface of the box body, and one side of the receiving plate is fixedly connected to the adjusting rack; the adjusting motor is fixedly arranged on the inner wall of the box body, the output shaft of the adjusting motor penetrates through the box body and extends to the outside of the box body, and the adjusting gear meshing with the adjusting rack is fixedly arranged on the outer end of the output rod of the adjusting motor.

[0018] By adopting the above technical solution, when the receiving plate needs to slide up and down, the adjusting motor is started to drive the adjusting gear to rotate coaxially. Since the adjusting gear and the adjusting rack are meshed with each other, the adjusting rack and the receiving can be driven to slide reciprocally in the up and down direction.

[0019] Optionally, flow guiding members are arranged on two opposite vertical side surfaces of the receiving plate. The flow guiding members include compression springs and flow guiding inclined blocks; placing grooves for placing the compression springs and the flow guiding inclined blocks are formed in the receiving plate. The compression springs extrude the flow guiding inclined blocks so that a part of the flow guiding inclined blocks protrudes out of the placing grooves. The upper side surface of the protruding part of the flow guiding inclined blocks is an inclined surface inclined downward, and the flow guiding inclined blocks can be completely extruded into the interior of the placing grooves.

[0020] By adopting the above technical solution, when the receiving plate seals the diversion notch, the diversion inclined block is completely squeezed into the placement groove at this time; when the receiving plate releases the seal of the diversion notch, under the extrusion of the compression spring, a part of the diversion inclined block protrudes from the opening of the placement groove, and the rainwater passing through the diversion notch can slide down along the guiding inclined surface better to the ground, limiting the falling direction of the rainwater and reducing the impact of the splashing rainwater on the box body.

[0021] Optionally, a guiding chute is formed on the guiding inclined surface along the inclined downward direction.

[0022] By adopting the above technical solution, the process of the rainwater sliding down along the guiding inclined surface to the ground is better limited, further reducing the impact of the splashing rainwater on the box body.

[0023] Optionally, an upper protective cover with an upward opening is fixedly provided on the inner wall of the box body at the inner opening edge of the diversion hole.

[0024] By adopting the above technical solution, the inner opening of the diversion hole is protected, thereby reducing the possibility of external rainwater, dust or other impurities entering the box body through the diversion hole.

[0025] Optionally, a protective net is fixedly provided on the inner edge of the upper opening of the upper protective cover.

[0026] By adopting the above technical solution, the inner opening of the diversion hole is further protected through the setting of the protective net.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. Due to the setting of the temperature sensor, the diversion fan and the diversion hole, during the operation of the box-type substation, the temperature sensor can be used to detect the temperature inside the box body and remotely feedback the real-time temperature inside the box, and can automatically control the operation of the diversion fan according to the temperature inside the box, thereby controlling the exchange and circulation of the internal and external gases of the box body through the diversion hole, and adjusting the heat dissipation performance of the box-type substation, reducing the problem that the internal electrical equipment is damaged due to overheating inside the box body.

[0034] Among them, the cover 2 is larger than the cross-sectional dimension of the box body 1, and there are two symmetric diversion inclined surfaces 21 on the side of the cover 2 away from the box body 1; when it rains outdoors, the box body 1 can be better protected by the cover 2, and the rainwater can slide down along the diversion inclined surfaces 21 to the ground.

[0035] Refer to Figure 2 and Figure 3 , a diversion hole 12 is opened in the upper part of the vertical side of the box body 1, a diversion fan 8 is embedded on the inner wall of the diversion hole 12, and a temperature sensor 9 is fixedly arranged on the inner wall of the box body 1.

[0036] Refer to Figure 2 and Figure 3 , a confluence groove 22 is opened on the cover 2 around the side edge away from the box body 1. Among them, the lowest side of the diversion inclined surface 21 is flush with the bottom side of the confluence groove 22, and a diversion notch 221 is opened on the bottom side of the confluence groove 22; when it rains, the rainwater sliding along the diversion inclined surface 21 is first injected into the confluence groove 22, and then discharged to the ground from the diversion notch 221.

[0037] The implementation principle of the embodiment of the present application is as follows: During the operation of the box-type substation, the temperature sensor 9 can be used to detect the temperature inside the box body 1 and remotely feedback the real-time temperature inside the box body 1, and can automatically control the operation of the diversion fan 8 according to the temperature inside the box body 1, thereby adjusting the heat dissipation performance of the box-type substation.

The state of the receiving plate 3 sliding downward can not only release the blockage of the diversion notch 221, but also be used for protecting the outer opening of the diversion hole 12.

[0039] Refer to Figure 5 and Figure 6, the adjusting member 5 includes an adjusting rack 51, an adjusting gear 52 and an adjusting motor 53. The adjusting rack 51 is slidably arranged on the outer side surface of the box body 1 in the vertical direction, and one side of the receiving plate 3 is fixedly connected to the adjusting rack 51; the adjusting motor 53 is fixedly arranged on the inner wall of the box body 1 in the horizontal direction, the output shaft of the adjusting motor 53 penetrates through the box body 1 and extends to the outside of the box body 1, and the adjusting gear 52 is fixedly arranged on the outer end of the output rod of the adjusting motor 53; when the adjusting gear 52 is installed, it meshes with the tooth part on the adjusting rack 51. When the adjusting motor 53 is started, it drives the adjusting gear 52 to rotate coaxially, and then drives the adjusting rack 51 and the receiving plate to slide reciprocally in the up and down directions; When it does not rain outside, slide the adjusting rack 51 and the receiving plate 3 upward to the limit position, and the receiving plate 3 blocks the diversion notch 221. At this time, the protection of the outer opening of the diversion hole 12 is also removed; when it rains, slide the adjusting rack 51 and the receiving plate 3 downward to the limit position. At this time, the receiving plate 3 removes the blockage of the diversion notch 221, and the rainwater flowing into the diversion groove can be discharged through the diversion notch 221. And at this time, the receiving plate 3 simply protects the outer opening of the diversion hole 12.

[0040] Refer to Figure 5 and Figure 7 , diversion members 6 are arranged on both vertical side surfaces of the receiving plate 3 opposite to each other. The diversion member 6 includes a compression spring 61 and a diversion inclined block 62; a placement groove 31 for placing the compression spring 61 and the diversion inclined block 62 is provided on the receiving plate 3. The compression spring 61 squeezes the diversion inclined block 62 so that a part of the diversion inclined block 62 protrudes from the placement groove 31, and the upper side surface of the protruding part of the diversion inclined block 62 is a guiding inclined surface 621 that slopes downward; When the receiving plate 3 blocks the diversion notch 221, at this time, the diversion inclined block 62 is completely squeezed into the placement groove 31; when the receiving plate 3 removes the blockage of the diversion notch 221, under the extrusion of the compression spring 61, a part of the diversion inclined block 62 protrudes from the opening of the placement groove 31.

[0041] Refer to Figure 5 , a guiding chute 622 is arranged on the guiding inclined surface 621 along the direction sloping downward. When it rains, the receiving plate 3 moves downward, and a part of the diversion inclined block 62 protrudes from the opening of the placement groove 31. The rainwater can slide down along the guiding chute 622 on the guiding inclined surface 621 to the ground.

[0042] Refer to Figure 8 and Figure 9, on the inner wall of the box body 1, an upper protective cover 13 with an upward opening is fixedly arranged at the inner opening edge of the diversion hole 12, and a protective net 131 is fixedly arranged on the inner edge of the upper opening of the upper protective cover 13; on the outer opening edge of the diversion hole 12 of the box body 1, a lower protective cover 14 with a downward opening is fixedly arranged, and a blocking plate 141 is fixedly arranged on the bottom opening of the lower protective cover 14, and a plurality of blocking holes 1411 are formed in the blocking plate 141; thereby reducing the possibility of rainwater, dust, small flying insects or other impurities in the outside world entering the interior of the box body 1 through the diversion hole 12.

[0043] Refer to Figure 8 , Figure 9 and Figure 10 , on the side of the blocking plate 141 away from the lower protective cover 14, a plugging plate 7 is slidably arranged in the horizontal direction, wherein a plugging hole 71 coinciding with the blocking hole 1411 is formed in the plugging plate 7, and the plugging plate 7 can slide reciprocally in the direction close to the box body 1; the bottom edge of the bearing plate 3 is hinged with a control rod 32, and the other end of the control rod 32 is hinged with the side edge of the plugging plate 7 away from the box body 1; When it rains, the bearing plate 3 slides downward to the limit position, and drives the plugging plate 7 to slide in the direction close to the box body 1 through the control rod 32, so that the plugging hole 71 and the blocking hole 1411 are misaligned, thereby completely blocking the lower opening of the lower protective cover 14; when it does not rain, the bearing plate 3 slides upward to the limit position, and drives the plugging plate 7 to slide in the direction away from the box body 1 through the control rod 32, so that the plugging hole 71 and the blocking hole 1411 coincide, enabling the diversion hole 12 to play a normal heat dissipation role.

[0044] The implementation principle of the embodiment of the present application is as follows: When it does not rain outside, the diversion fan 8 is in an open state, the adjusting rack 51 and the bearing plate 3 are slid upward to the limit position, and the bearing plate 3 blocks the diversion notch 221. At this time, the protective shielding of the outer opening of the diversion hole 12 is also removed; and the plugging plate 7 is driven to slide in the direction away from the box body 1 through the control rod 32, so that the plugging hole 71 and the blocking hole 1411 coincide, enabling the diversion hole 12 to play a normal heat dissipation role; When it rains, the diversion fan 8 is in a closed state, the adjusting rack 51 and the bearing plate 3 are slid upward to the limit position, and the bearing plate 3 blocks the diversion notch 221. At this time, the protective shielding of the outer opening of the diversion hole 12 is also removed; and the plugging plate 7 is driven to slide in the direction close to the box body 1 through the control rod 32, so that the plugging hole 71 and the blocking hole 1411 are misaligned, thereby completely blocking the lower opening of the lower protective cover 14.
