Description

Technical Field

[0001] This invention relates to the field of smart grid technology, and in particular to a prefabricated substation with intelligent ventilation for high temperature early warning. Background Technology

[0002] With rapid social development and technological advancements, people's demand for electricity is increasing, and the requirements for the stability and security of power systems are also becoming more stringent. Especially in power supply processes such as 750 kV and above AC transmission, large-scale power grid security and defense systems, and intelligent dispatching systems, substations, as the core component of the power system, are crucial for ensuring power supply when operating normally.

[0003] To prevent substations from generating high temperatures during operation and causing a series of problems, ventilation systems are usually installed to improve airflow and reduce the temperature. However, this method is only suitable for substations with good installation environments. In coastal cities or offshore wind power platforms, direct ventilation in extreme salt spray weather can lead to a large amount of salt spray entering the substation, severely corroding the metal casings of equipment and electrical components. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a prefabricated substation with intelligent ventilation for high-temperature early warning; including the substation, and further including a cooling mechanism disposed on the substation, the cooling mechanism comprising: A duct is slidably installed through the substation. An electric fan blade is installed inside the duct. Guide rods are symmetrically fixedly installed on the duct and slidably installed through the substation. The first filter plate is fixedly installed inside the air duct. The first sealing plate is fixedly installed on the two guide rods, and the rotating shaft of the electric fan blade rotates through the first filter plate and the first sealing plate; The second filter plate is installed inside a ventilation hole that is provided through the rear side of the substation. The second sealing plate is located inside the substation and is used to block the ventilation holes. An internal circulation mechanism installed on the substation includes: A fin frame is slidably mounted on the substation, and a second enclosure plate is fixedly mounted on the fin frame.

[0005] Furthermore, it is particularly preferred that the internal circulation mechanism also includes an arc-shaped plate fixedly installed inside the substation, and the air duct has a first through hole, the arc-shaped plate being used to seal the first through hole.

[0006] Furthermore, it is particularly preferred that the internal circulation mechanism also includes an air guide frame fixedly installed on the arc-shaped plate, and the fin frame has a second through hole, the air guide frame being used to allow the first through hole of the air guide pipe to communicate with the second through hole of the fin frame.

[0007] Furthermore, it is particularly preferred that the substation also includes a drive assembly, which includes a detection element installed on the substation. Electric push rods electrically connected to the detection element are symmetrically installed in the substation. The telescopic end of the electric push rod is fixedly installed to the fin frame. A pair of support plates are fixedly installed between the fin frame and the air guide pipe.

[0008] Furthermore, it is particularly preferred that the substation is equipped with an efficiency enhancement mechanism, which includes a circular tube disposed on one side of the fin frame, an air pump installed on the circular tube, and two sets of air outlet boxes connected to it.

[0009] Furthermore, it is particularly preferred that the efficiency-enhancing mechanism also includes a T-shaped frame fixedly installed on the fin frame, the T-shaped frame being slidably installed through the substation, a reciprocating screw being rotatably installed on the T-shaped frame, the reciprocating screw being rotatably connected to the first sealing plate, a first bevel gear being fixedly connected to the rotating shaft of the electric fan blade, a second bevel gear being fixedly connected to the reciprocating screw and meshing with the first bevel gear, and a connecting block being rotatably sleeved on the round tube, the connecting block being threadedly connected to the reciprocating screw.

[0010] Furthermore, it is particularly preferred that the efficiency enhancement mechanism also includes a rectangular plate located on the other side of the fin frame, the rectangular plate having a through-cut wave groove, and a slide rod located within the wave groove being fixedly installed at the end of the round tube.

[0011] Furthermore, it is particularly preferred that a first bracket and a second bracket are fixedly installed on the fin frame, both of which are slidably installed on the substation, and the rectangular plate is slidably installed inside the first bracket and the second bracket. A first elastic limiting block is slidably installed inside the first bracket, and a first slot matching the first elastic limiting block is provided on the rectangular plate.

[0012] Furthermore, it is particularly preferred that a second elastic limiting block is slidably installed inside the second bracket, and a second slot matching the second elastic limiting block is provided on the rectangular plate.

[0013] Furthermore, it is particularly preferred that the rectangular plate is limited by the first elastic limiting block and the second elastic limiting block, thereby changing the movement trajectory of the air outlet box.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a cooling mechanism, can cool the substation by controlling the rotation of electric fan blades when the environment is good and the substation is hot. In extreme salt spray environments and when the substation is hot, the first sealing plate can be attached to the top of the substation to prevent salt spray from entering the substation. The internal circulation mechanism can also cool the substation. This invention improves the safety and stability of substations, especially in power supply processes such as 750 kV and above AC transmission, large-scale power grid security and defense systems, and intelligent dispatching systems.

[0015] 2. By setting up an efficiency-enhancing mechanism, this invention enables heat exchange between the fin frame and the substation by blowing air through two sets of air outlet boxes when the environment is good and the substation is hot. In extreme salt spray environments and when the substation is hot, the internal circulation mechanism enables air to flow in the gap between the fin frame and the substation, thereby reducing the temperature of the air flowing in the substation and ensuring the cooling effect on the substation.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0030] Example A prefabricated substation with intelligent ventilation and high-temperature early warning system, such as Figures 1-5 As shown, the system includes a substation 1 and a cooling mechanism mounted on the substation 1. The cooling mechanism includes a duct 201 that slides through the substation 1. An electric fan blade 202 is installed inside the duct 201. Guide rods 203 are symmetrically fixedly mounted on the outer wall of the duct 201. Both guide rods 203 slide through the substation 1. A first filter plate 204 for filtering salt spray is fixedly mounted on the top of the inner wall of the duct 201. A first sealing plate 204 is fixedly mounted on the top of both guide rods 203. 5. The rotating shaft of the electric fan blade 202 passes through the first filter plate 204 and the first sealing plate 205. A ventilation hole is provided through the rear side of the substation 1. A second filter plate 206 for filtering salt spray is installed in the ventilation hole. A second sealing plate 207 is provided on the rear side of the inner wall of the substation 1. The second sealing plate 207 is used to block the ventilation hole. An internal circulation mechanism is provided on the substation 1. The internal circulation mechanism includes a fin frame 208 that is slidably installed through the substation 1. The second sealing plate 207 is fixedly installed on the rear side of the fin frame 208.

[0031] like Figure 2 and Figure 6As shown, the internal circulation mechanism also includes an arc-shaped plate 301 fixedly installed on the top of the inner wall of the substation 1. The arc-shaped plate 301 is attached to the outer wall of the air duct 201. A first through hole is opened on the rear side of the air duct 201, and the arc-shaped plate 301 is used to block the first through hole.

[0032] like Figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, the internal circulation mechanism also includes an air guide frame 401 fixedly installed at the bottom of the arc plate 301. A second through hole is provided on the front side of the fin frame 208. The air guide frame 401 is used to connect the first through hole of the air guide duct 201 with the second through hole of the fin frame 208.

[0033] like Figure 7 As shown, it also includes a drive assembly installed on the substation 1. The drive assembly includes a detection element 402 installed on the top of the substation 1. The detection element 402 is used to detect the salt spray concentration in the air. Electric push rods 403 electrically connected to the detection element 402 are symmetrically installed on the left and right sides of the inner wall of the substation 1. The telescopic ends of the two electric push rods 403 are fixedly installed to the bottom of the fin frame 208. A pair of support plates are fixedly installed between the front side of the fin frame 208 and the outer wall of the air duct 201.

[0034] Initially, the telescopic end of the electric push rod 403 is in the extended state, the top of the air duct 201 is at the same level as the top of the substation 1, the first through hole of the air duct 201 is blocked by the arc plate 301, and the second sealing plate 207 is misaligned with the second filter plate 206. When the concentration of salt spray in the external environment is low and high temperature is generated inside the substation 1, the electric fan blade 202 is controlled to rotate. The rotation of the electric fan blade 202 generates a downward airflow. The external air enters the air duct 201 through the first filter plate 204. The first filter plate 204 filters the salt spray in the external air to prevent the salt spray from entering the substation 1. The electric fan blade 202 blows the air into the substation 1 through the air duct 201 to cool the interior of the substation 1. The air inside the substation 1 is discharged through the second filter plate 206, thus achieving cooling of the substation 1 under normal weather conditions.

[0035] In extreme salt spray weather and when high temperatures are generated inside substation 1, the detection element 402 detects excessively high levels of environmental salt spray. The detection element 402 controls the retraction of the telescopic ends of two electric push rods 403. These telescopic ends cause the fin frame 208 to slide and descend along substation 1. The fin frame 208, via a pair of support plates, causes the air duct 201 to descend, and also causes the second sealing plate 207 to descend. The air duct 201 causes the electric fan blades 202 and the first filter plate 204 inside it to descend, and via two guide rods 203, causes the first sealing plate 205 to descend until the telescopic ends of the electric push rods 403 are fully retracted, causing the first sealing plate 205 to adhere to the top of substation 1. The first sealing plate 205 seals the top of substation 1, while the second sealing plate 207 seals the ventilation holes of substation 1, preventing external air from entering substation 1. This prevents salt spray from entering substation 1. To prevent excessive salt spray from passing through the first filter plate 204 and the second filter plate 206, which would reduce the permeability of the first filter plate 204 and the second filter plate 206, the first through hole of the air duct 201 and the second through hole of the fin frame 208 are connected through the air guide frame 401. This controls the rotation of the electric fan blade 202. When the electric fan blade 202 rotates, the air in the substation 1 flows downward under the action of the electric fan blade 202. The air on the rear side of the inner wall of the substation 1 flows upward and enters the gap between the fin frame 208 and the inner wall of the substation 1. After the air rises to the top of the gap, it flows forward and enters the air duct 201 through the second through hole of the fin frame 208, the air guide frame 401 and the first through hole of the air duct 201, so that the air in the substation 1 circulates. When the air passes through the fin frame 208, it exchanges heat with the fin frame 208, thereby achieving air circulation and cooling in the substation 1 under extreme salt spray weather.

[0036] like Figure 9 and Figure 10 As shown, substation 1 is equipped with an efficiency enhancement mechanism, which includes a circular tube 501 located above the front side of the fin frame 208. An air pump 5011 is installed at the left end of the circular tube 501, and two sets of air outlet boxes 502 are connected to the bottom of the circular tube 501, with four air outlet boxes in each set.

[0037] like Figure 9 and Figure 10 As shown, the efficiency enhancement mechanism also includes a T-shaped frame 601 fixedly installed on the rear side of the fin frame 208. The T-shaped frame 601 is slidably installed on the substation 1. A reciprocating screw 602 is rotatably installed on the upper front side of the T-shaped frame 601. The reciprocating screw 602 is rotatably connected to the first sealing plate 205. A first bevel gear is fixedly connected to the top of the rotating shaft of the electric fan blade 202. A second bevel gear that meshes with the first bevel gear is fixedly connected to the front end of the reciprocating screw 602. A connecting block 603 is rotatably sleeved on the middle of the outer wall of the round tube 501. The connecting block 603 is threadedly connected to the reciprocating screw 602.

[0038] like Figure 10 and Figure 11 As shown, the efficiency enhancement mechanism also includes a rectangular plate 701 located on the right side of the fin frame 208. A wave groove is provided through the rectangular plate 701. A slide rod 702 located in the wave groove is fixedly installed at the right end of the round tube 501. When the slide rod 702 slides along the wave groove, it can cause the round tube 501 to drive the two sets of air outlet boxes 502 to swing.

[0039] like Figure 11 and Figure 12 As shown, a first bracket 801 is fixedly installed on the front side of the fin frame 208, and a second bracket 802 is fixedly installed on the rear side of the fin frame 208. Both the first bracket 801 and the second bracket 802 are slidably installed on the substation 1. A rectangular plate 701 is slidably installed in the first bracket 801 and the second bracket 802 in the front-back direction. A first elastic limiting block 803 is slidably installed in the first bracket 801. A first slot matching the first elastic limiting block 803 is opened on the top front side of the rectangular plate 701.

[0040] like Figure 12 As shown, a second elastic limiting block 901 is slidably installed inside the second bracket 802. A second slot matching the second elastic limiting block 901 is provided on the rectangular plate 701. The second elastic limiting block 901 can be inserted into the second slot to limit the rectangular plate 701. By limiting the rectangular plate 701 through the first elastic limiting block 803 and the second elastic limiting block 901, the movement trajectory of the air outlet box 502 can be changed.

[0041] Initially, the first elastic limiting block 803 is engaged in the first slot of the rectangular plate 701 to limit the rectangular plate 701. When the electric fan blade 202 rotates, the shaft of the electric fan blade 202 drives the first bevel gear to rotate. The first bevel gear drives the reciprocating screw 602 to rotate through the second bevel gear. The reciprocating screw 602 drives the circular tube 501 to reciprocate back and forth through the connecting block 603. The circular tube 501 drives the air pump 5011 and the two sets of air outlet boxes 502 on it to reciprocate back and forth. At the same time, the air pump 5011 is controlled to input air into the circular tube 501. The air enters the two sets of air outlet boxes 502 along the circular tube 501 and blows towards the fin frame 208 through the two sets of air outlet boxes 502. When the circular tube 501 moves, it drives the slide rod 702 to move. The slide rod 702 moves along the rectangular plate 701. The wavy groove of plate 701 slides, causing the circular tube 501 to rotate reciprocally. The circular tube 501 causes the two sets of air outlet boxes 502 on it to swing reciprocally, thereby increasing the blowing area of ​​the air outlet boxes 502 and rapidly cooling the part of the fin frame 208 exposed outside the substation 1. The fin frame 208 contacts the substation 1 for heat exchange, reducing the temperature of the substation 1. When the slide rod 702 slides to the rear end of the wavy groove of the rectangular plate 701, the circular tube 501 continues to drive the slide rod 702 to move backward. The slide rod 702 squeezes the wavy groove, causing the rectangular plate 701 to slide backward. The first slot of the rectangular plate 701 squeezes the first elastic limiting block 803, and the first elastic limiting block 803 elastically contracts and slides. Subsequently, the outer wall of the rectangular plate 701 contacts the second elastic limiting block 901 and... When compressed, the second elastic limiting block 901 contracts and slides under pressure until the connecting block 603 moves to the rear end of the reciprocating screw 602. The first elastic limiting block 803 then releases its elastic release from the rectangular plate 701. At this point, the second slot of the rectangular plate 701 aligns with the second elastic limiting block 901, and the second elastic limiting block 901 releases its elastic release and slides into the second slot, limiting the rectangular plate 701. The reciprocating screw 602 continues to rotate, causing the connecting block 603 to drive the circular tube 501 forward. The circular tube 501 then drives the two sets of air outlet boxes 502 on it forward. Because the position of the rectangular plate 701 changes at this time, the sliding rod 702, under the action of the wave groove, changes the swing trajectory of the circular tube 501, thereby changing the movement of the two sets of air outlet boxes 502. The trajectory allows the two sets of air outlet boxes 502 to blow air onto different positions of the fin holder 208, improving the heat exchange efficiency of the fin holder 208. When the slide rod 702 slides to the front end of the wave groove, the slide rod 702 presses against the wave groove, causing the rectangular plate 701 to slide forward. The second slot of the rectangular plate 701 presses against the second elastic limiting block 901, and the second elastic limiting block 901 elastically contracts and slides. Subsequently, the outer wall of the rectangular plate 701 contacts and presses against the first elastic limiting block 803, and the first elastic limiting block 803 elastically contracts and slides under force until the connecting block 603 moves to the front end of the reciprocating screw 602. The second elastic limiting block 901 disengages from the rectangular plate 701 and elastically releases and slides. At this time, the first slot of the rectangular plate 701 is aligned with the first elastic limiting block 803.The first elastic limiting block 803 elastically releases and slides into the first slot to limit the rectangular plate 701. The reciprocating screw 602 continues to rotate and repeats the above steps to achieve the same effect.

[0042] When the detection element 402 detects that the ambient salt spray is too high, causing the electric fan blade 202 and the fin holder 208 to descend, the shaft of the electric fan blade 202 drives the first bevel gear to descend, the fin holder 208 drives the T-shaped frame 601 to descend, the T-shaped frame 601 and the first sealing plate 205 together drive the reciprocating screw 602 to descend, the reciprocating screw 602 drives the circular tube 501 to descend through the connecting block 603, the circular tube 501 drives the two sets of air outlet boxes 502 on it to descend, at the same time the fin holder 208 drives the first bracket 801 and the second bracket 802 to descend, the first bracket 801 and the second bracket 802 drive the rectangular plate 701 to descend, thereby realizing the internal circulation cooling of the substation 1.

[0043] When the concentration of salt spray in the external environment decreases, the detection element 402 detects the decrease and controls the extension ends of the two electric push rods 403 to extend. The extension ends of the two electric push rods 403 drive the fin frame 208 to rise and slide back along the substation 1. The fin frame 208 drives the air duct 201 to rise and slide back through a pair of support plates, and also drives the second sealing plate 207 to rise and reset. The air duct 201 drives the electric fan blades 202 and the first filter plate 204 inside to rise and reset, and drives the first sealing plate 205 to rise and reset through two guide rods 203. After the second sealing plate 207 resets, it no longer blocks the ventilation holes of the substation 1. The arc plate 301 supports the air duct 201. The first through hole is sealed, and at the same time, the rotating shaft of the electric fan blade 202 drives the first bevel gear to lift and reset. The fin frame 208 drives the T-shaped frame 601 to lift and slide to reset. The T-shaped frame 601 and the first sealing plate 205 together drive the reciprocating screw 602 to lift and reset. The reciprocating screw 602 drives the circular tube 501 to lift and reset through the connecting block 603. The circular tube 501 drives the two sets of air outlet boxes 502 on it to lift and reset. At the same time, the fin frame 208 drives the first bracket 801 and the second bracket 802 to lift and slide to reset. The first bracket 801 and the second bracket 802 drive the rectangular plate 701 to lift and reset. In this way, the cooling mode of the substation can be switched according to the salt spray concentration of the external environment. Especially in the process of power supply such as 750 kV and above AC transmission, large-scale power grid security and defense system and intelligent dispatch system, the safety and stability of the substation are improved.
