A highly integrated prefabricated substation

Abstract

This invention relates to the field of prefabricated substation technology, specifically a highly integrated prefabricated substation comprising a water collection cover. A filter screen is mounted on the front top of the water collection cover. The water collection cover is equipped with a suction and cooling mechanism for heat dissipation and reciprocating scraping for cleaning. This invention utilizes the suction and cooling mechanism to drive the wind-driven components, facilitating air cooling. The water collection cover collects rainwater, which is then used for water cooling of the prefabricated substation. This combination of two cooling methods enhances the heat dissipation effect. The wind-driven components simultaneously drive the reciprocating motion of the scraping components, effectively preventing clogging of the filter screen. When rainwater enters the water collection cover, it drives the floating frame and its lifting rod upwards, achieving automatic drainage. During the upward movement, the linkage squeezing components simultaneously move, preventing clogging of the bottom of the filter screen.

Description

Technical Field

[0001] This invention belongs to the technical field of prefabricated substations, specifically relating to a highly integrated prefabricated substation. Background Technology

[0002] Prefabricated substations, also known as modular substations or box-type substations, are compact indoor or outdoor substations that combine high-voltage switchgear, distribution transformers, and low-voltage distribution equipment according to a specific wiring scheme. They can convert voltage levels from 10kV or higher to the commonly used 380V / 220V and directly supply power to users. Prefabricated substations are suitable for mines, factories, oil and gas fields, and wind power stations. They replace traditional civil engineering substations and become a new type of complete power distribution system. However, existing prefabricated substations have the following problems in use:

[0003] 1. Prefabricated substations are usually used directly outdoors. During use, the heat generated by the internal equipment and the external exposure to sunlight can lead to high internal temperatures in the prefabricated substation, causing overheating damage to components, reduced equipment efficiency, and shortened service life. Therefore, it is necessary to cool the substation. However, existing substations usually use air cooling, water cooling, or a combination of both. However, no matter which cooling method is used, although it achieves the cooling effect, it increases energy consumption.

[0004] 2. Existing water cooling systems typically utilize heat exchangers such as copper tubes to directly contact heat-generating components, thereby achieving water cooling for these components. However, a single heat exchanger can only cool one component at a time, making it difficult to cool the overall environment inside the prefabricated substation. This results in poor cooling performance and low efficiency. Summary of the Invention

Additionally, a water collection cover is used to collect rainwater, which is then used for water cooling of the prefabricated substation. The combination of these two cooling methods enhances the overall cooling effect.

[0021] 2. Compared with existing technologies, using rainwater as a heat dissipation medium eliminates the need for water pumps to draw clean water for heat dissipation, saving heat dissipation costs. Furthermore, rainwater flows through columns, supports, horizontal partitions, and vertical partitions, achieving overall heat dissipation of the prefabricated substation with a larger heat dissipation area compared to single-point water cooling of components, thus improving heat dissipation efficiency.

This invention uses a wind-driven component to synchronously drive the reciprocating motion of the scraping component, thereby achieving reciprocating scraping of the top of the filter screen and effectively preventing clogging. When rainwater enters the water collection cover, it drives the floating frame and the lifting rod on it to move upward, achieving automatic drainage and avoiding the problem of rainwater overflow. During the upward movement, it synchronously drives the linkage squeezing component to achieve scraping and clogging of the bottom of the filter screen. Attached Figure Description

[0037] Example: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 11A highly integrated prefabricated substation includes a water collection cover 1, a filter screen 2 on the front top of the water collection cover 1, a heat dissipation mechanism 3 for suction and reciprocating scraping cleaning on the water collection cover 1, a partition compartment 9 fixedly installed at the bottom of the water collection cover 1, and insertion pipes 18 fixedly installed at the four corners of the bottom of the partition compartment 9.

The top of the water inlet trough 13 is connected to the inside of the water collection cover 1. A buoyancy lifting mechanism 8 is set together between the water collection cover 1, the support column 7, and the column 4.

[0038] In use, the water collection cover 1 is used to collect rainwater, the filter screen 2 is used to filter the rainwater entering the water collection cover 1, the suction and heat dissipation mechanism 3 is used to suction and dissipate heat inside the box-type substation while scraping the top of the filter screen 2, effectively reducing the probability of filter screen 2 clogging, the insertion pipe 18 at the bottom of the partition compartment 9 is used to realize the insertion and fixing between the insertion pipe 18 and the column 4, the cavity divided by the vertical partition 14 and the horizontal partition 11 is used to place equipment such as transformers, low voltage cabinets and capacitors, and the buoyancy lifting mechanism 8 is used to realize automatic drainage and automatic scraping and anti-clogging of the bottom of the filter screen 2.

[0039] Please see Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 11 The interiors of multiple support columns 7 and multiple upright columns 4 are hollow. The top of the support column 7 can be moved through the partition compartment 9 and then communicate with the interior of the water collection cover 1. A sealing ring is provided between the water collection cover 1 and the support column 7. Air inlets 12 are provided at the bottom of multiple boxes 5. A sealing ring is provided between the insertion pipe 18 and the upright column 4. The top of the insertion pipe 18 is fixedly inserted through the partition compartment 9 and communicates with the interior of the water collection cover 1. Guide plates 17 are fixedly installed at the bottom of the internal cavities of the horizontal partition 11 and the vertical partition 14. The horizontal partition 11 has a first connecting hole 16 on both sides that communicates with the interior of the support column 7. The vertical partition 14 has a second connecting hole at the bottom that communicates with the interior of the support column 7.

[0040] In use, the cavities inside the support column 7, upright column 4, vertical partition 14 and horizontal partition 11 are used to store rainwater. After being filtered by the filter screen 2, the rainwater enters the water collection cover 1, then enters the support column 7 and upright column 4, and then enters the vertical partition 14 and horizontal partition 11 through the water inlet trough 13. The rainwater stored in the above structure is used to dissipate heat from the components inside the box-type substation.

[0041] Please see Figure 2 , Figure 7 , Figure 8 and Figure 9 The suction and heat dissipation mechanism 3 includes a wind-driven assembly 31, a scraping assembly 32, and a suction main pipe 33. The suction main pipe 33 is located at the top center of the water collection cover 1, and its bottom is fixedly inserted through the top center of the partition compartment 9. The wind-driven assembly 31 is mounted on the suction main pipe 33, and the scraping assembly 32 is mounted on the wind-driven assembly 31. The wind-driven assembly 31 includes a drive shaft 313 that rotates through the top center of the suction main pipe 33. Several fixing rods 312 are evenly installed on the top exterior of the drive shaft 313. An air scoop 311 is fixedly installed at the end of the fixing rod 312 away from the drive shaft 313. The air scoop 311 is detachable and can be replaced with different sizes according to actual usage needs, i.e., at high altitudes. When used in areas with strong winds, a smaller size air scoop 311 can be used. When used in areas with low altitude and weak winds, a larger size air scoop 311 can be used to ensure sufficient wind power to drive the mechanism. The drive shaft 313 is fixedly sleeved with a drive bevel gear 314 in the middle. Two triangular brackets 317 are symmetrically fixedly installed on the inner wall of the top of the main exhaust pipe 33. A connecting shaft 316 is rotatably installed between the two triangular brackets 317. A driven bevel gear 315 that meshes with the drive bevel gear 314 is fixedly sleeved on the left end of the connecting shaft 316. Several suction fan blades 318 are evenly fixedly installed on the outside of the connecting shaft 316. The bottom of the drive shaft 313 rotates through the bottom of the main exhaust pipe 33.

[0042] Please see Figure 7 , Figure 8 , Figure 9 and Figure 10A plurality of suction branch pipes 34 are evenly fixedly installed at the bottom of the main suction pipe 33 via an installation plate. The interior of the suction branch pipes 34 is connected to the interior of the main suction pipe 33. The end of the suction branch pipe 34 away from the main suction pipe 33 is fixedly inserted through the bottom of the partition chamber 9 and then fixedly connected to the suction cover 35. The scraping assembly 32 includes a worm gear 321 fixedly sleeved at the bottom of the drive shaft 313. A protective box 38 is fixedly installed at the bottom of the main suction pipe 33. A conveying shaft 329 is rotatably inserted through the left side of the protective box 38. A worm wheel 322 that meshes with the worm gear 321 is fixedly sleeved at one end of the conveying shaft 329. A bearing plate 323 is rotatably sleeved in the middle of the conveying shaft 329. The other end of the conveying shaft 329 is fixedly... A turntable 328 is fixedly installed, and a fixing pin is fixedly installed at an eccentric position on the turntable 328. A connecting rod 327 is hinged to the fixing pin. A limit slider 326 is hinged to the end of the connecting rod 327 away from the turntable 328. The limit slider 326 is slidably installed on the top of the limit slide rail 325. The limit slide rail 325 is fixedly installed on the top of the water collection cover 1. A fixing frame 324 is fixedly installed on the front side of the top of the limit slider 326. An installation plate 37 is fixedly installed on the end of the fixing frame 324 away from the limit slider 326. Several scrapers 36 are evenly installed on the bottom of the installation plate 37. The scrapers 36 are located on the filter screen 2. A protective box 38 is sleeved on the outside of the worm gear 321 and the worm wheel 322.

[0043] During operation, the suction cooling mechanism 3 firstly uses external wind to rotate the air scoop 311 and its fixed rod 312, which in turn rotates the drive shaft 313 and its driving bevel gear 314, which in turn rotates the driven bevel gear 315 and its connecting shaft 316. Simultaneously, the suction fan blades 318 rotate to draw in hot air from the enclosure of the box-type substation, which is formed by the box door 5, the support column 7, and the upright column 4, through the suction hood 35 into the suction branch pipe 34. The hot air then enters the main exhaust pipe 33 and is discharged, thus achieving suction cooling of the box-type substation enclosure. Meanwhile, cool air from the outside enters the box-type substation through the air inlet 12, achieving circulating air cooling of the box-type substation. No external power source is required for cooling, resulting in good heat dissipation.

[0044] Please see Figure 2 , Figure 10 and Figure 11The buoyancy lifting mechanism 8 includes a float frame 85 disposed inside the water collection cover 1. A float plate 15 is fixedly installed on the inner wall of the float frame 85. The float plate 15 is made of EVA material and is used to provide buoyancy. Several fixing lugs 81 are fixedly installed on the side wall of the float frame 85. The float frame 85 is hollow inside. Several No. 1 springs 84 are evenly fixedly installed on the top of the float frame 85. The top of the No. 1 springs 84 is fixedly connected to the inner top surface of the water collection cover 1. Several lifting rods 83 are evenly fixedly installed on the fixing lugs 81 and the float frame 85. The lifting rods 83 are located inside the support column 7 and the upright column 4. A sealing plug 82 is fixedly installed at the bottom of the lifting rod 83. The bottom of the sealing plug 82 has a conical surface. A sealing seat 10 is fixedly installed at the bottom of the support column 7 and the upright column 4. The sealing seat 10 has a hole. The top of the hole is sealed and fitted to the bottom of the sealing plug 82. A linkage compression assembly 86 is provided on the float frame 85.

[0045] Please see Figure 2 , Figure 10 , Figure 11 and Figure 12 The linkage extrusion assembly 86 includes two mounting slide rails 867 symmetrically fixedly installed on the top surface inside the water collection cover 1. Mounting sliders 868 are slidably mounted on the bottom of each of the two mounting slide rails 867. A fixing strip 866 is fixedly mounted on the bottom of both mounting sliders 868. A cleaning brush 865 is fixedly mounted at the top center of the fixing strip 866. A second spring 869 is fixedly mounted between the mounting slider 868 and the front side of the mounting slide rail 867. A second connecting rod 864 is fixedly mounted at the front center of the fixing strip 866. A driven wedge 863 is fixedly mounted on the front side of the second connecting rod 864. A first connecting rod 861 is fixedly mounted on the float frame 85. An active wedge 862, which cooperates with the driven wedge 863, is fixedly mounted on the side of the first connecting rod 861 away from the float frame 85.

[0046] In use, when rainwater fills the support column 7, upright column 4, and water collection cover 1, the buoyancy of the water causes the float plate 15, float frame 85, and lifting rod 83 to move upwards, simultaneously causing the sealing plug 82 to move upwards, releasing the seal of the sealing seat 10. At this time, the rainwater in the support column 7 and upright column 4 is discharged from the holes in the sealing seat 10, preventing the rainwater from overflowing from the water collection cover 1 and achieving automatic drainage. Simultaneously, as the float frame 85 moves upwards, it also drives the first connecting rod 861 and its active wedge 862 to move upwards. The active wedge 862 presses against the driven wedge 863, causing the driven wedge to move upwards. The moving wedge 863 and its second connecting rod 864 move from front to back, simultaneously driving the fixing strip 866 and its cleaning brush 865 to move from front to back. The cleaning brush 865 cleans the bottom of the filter screen 2 from front to back, reducing the probability of filter screen 2 clogging. After the water is drained, under the elastic force of the first spring 84, the float frame 85 and its lifting rod 83 move downward, and the sealing plug 82 seals the sealing seat 10. At this time, under the elastic force of the second spring 869, the mounting slider 868 and its fixing strip 866 reset from back to front, realizing the back-to-back brushing of the cleaning brush 865.

[0047] It should be noted that, in the use of this highly integrated prefabricated substation, the support column 7 and the upright column 4 are first welded and fixed to the base 6, and the box door 5 is hinged and installed to the support column 7 and the upright column 4 according to the design drawings. Then, the insertion pipe 18 is inserted and fixed to the bottom of the partition compartment 9, ensuring communication between the insertion pipe 18 and the inside of the water collection cover 1. The insertion pipe 18 is then inserted and fixed into the upright column 4. A sealing ring is then installed between the upright column 4 and the insertion pipe 18 to ensure a good seal between them. The vertical partition plate 14 and the horizontal partition plate 11 are used to divide the interior of the prefabricated substation into several cavities. These cavities are used to house equipment such as transformers, low-voltage cabinets, and capacitors. After the equipment installation is completed, sufficient clean water can be poured into the water collection cover 1, the support column 7, and the upright column 4 to ensure that the highly integrated prefabricated substation has water-cooled heat dissipation capabilities in its initial state. Functionally, when there is sufficient wind outside, the wind-driven component 311 blows the wind scoop 311 in the wind-driven component 31, which then drives the fixed rod 312 to rotate. At the same time, it drives the transmission shaft 313 and the active bevel gear 314 on it to rotate, which drives the driven bevel gear 315 and the connecting shaft 316 on it to rotate. Simultaneously, it drives the suction fan blade 318 to rotate and suck up the hot air in the box-type substation enclosure formed by the box door 5, the support column 7 and the upright column 4. The hot air is sucked from the suction hood 35 into the suction branch pipe 34, and then into the main suction pipe 33 for discharge. This realizes the suction and heat dissipation of the box-type substation enclosure. The suction and heat dissipation mechanism 3 itself is one of the heat dissipation methods and does not need to work all the time. When there is wind outside, the suction and heat dissipation mechanism 3 is driven to work to realize air-cooled suction and heat dissipation. When there is no wind outside, water-cooled heat dissipation and air convection heat dissipation can be achieved by using the heat dissipation holes opened on the equipment box door 5.

[0048] When it rains, the rainwater is filtered by the filter screen 2 and enters the water collection cover 1. Then, the rainwater enters the vertical partition 14 and horizontal partition 11 through the inlet trough 13. The rainwater stored in this structure is used to dissipate heat from the internal components of the prefabricated substation. Compared to the single-point heat dissipation mode of traditional heat exchangers for electrical components, the heat dissipation effect is better. When the rainwater overflows the support column 7 and the upright column 4 and enters the water collection cover 1, the buoyancy of the water drives the float frame 85 and its lifting rod 83 to move upwards, simultaneously driving the sealing plug 82 to move upwards, releasing the seal of the sealing seat 10. At this time, the rainwater in the support column 7 and the upright column 4 is discharged from the holes in the sealing seat 10, preventing the rainwater from overflowing from the water collection cover 1 and achieving automatic drainage. Simultaneously, as the float frame 85 moves upwards, it also drives the first connecting rod 861 and its active wedge 862 to move upwards. Block 862 presses against driven wedge 863, causing driven wedge 863 and its second connecting rod 864 to move from front to back. At the same time, it causes fixed bar 866 and its cleaning brush 865 to move from front to back. The cleaning brush 865 cleans the bottom of filter screen 2 from front to back, reducing the probability of filter screen 2 clogging. After the water is discharged, under the elastic force of spring 84, float frame 85 and its lifting rod 83 move downward, and sealing plug 82 seals sealing seat 10. At this time, under the elastic force of spring 869, mounting slider 868 and its fixed bar 866 reset from back to front, realizing the back-to-back brushing of cleaning brush 865. The initial water filling can ensure that the high-integration box substation also has heat dissipation capacity even without wind, and the heat dissipation holes opened on the box door 5 of the high-integration box substation itself have air convection heat dissipation function.

[0049] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
