Description

Technical Field

[0001] This utility model relates to the field of portable substation building technology, and more specifically, to a skid-mounted substation building structure for fracturing. Background Technology

[0002] Firstly, due to the nature of use and weight of mobile substations, typical bases are prone to vibration and shaking during field transportation and hoisting. This is due to insufficient base strength, inconsistent center of gravity before and after transformer installation, collisions, and frequent hoisting, posing significant safety risks. Furthermore, inadequate designs for traction rope attachment points, thermal insulation, grounding, and drainage often result in poor performance in actual use. Typical mobile substations add simple "I"-shaped support beams at each limiting slot to prevent frame deformation due to hoisting rope compression. However, this design has a small overall load-bearing area, weak resistance to compression, and is prone to localized frame deformation, and is also limited by electrical clearance constraints.

[0003] During the maintenance and use of substations, safety accidents are prone to occur when the roof of the building lacks adequate protective measures. The roof drainage typically uses a flat cover, which easily leads to rainwater accumulation. Furthermore, the exposed drainage bends are susceptible to collision damage during transportation, hoisting, and use. Inadequate waterproofing and dustproofing design in the electrical room results in poor waterproofing, dustproofing, and drainage, affecting the lifespan of electrical equipment. Insufficient heat dissipation in the indoor electrical room significantly impacts the safe operation of electrical equipment. During hoisting and transportation, alarm devices exposed on the exterior of the building are easily damaged by collisions. Utility Model Content

[0089] The outer edge of the top cover 8 is provided with several fixing feet 57, which are evenly distributed on the outer edge of the top cover 8. The frame of the top cover 8 between the top sealing plate 46 and the bottom sealing plate 43 is filled with thermal insulation cotton 45, which enables the top cover 8 to have a thermal insulation effect and prevent damage to the electrical equipment inside the electrical room 3. The setting of the fastening groove 47 makes the top cover 8 firmly connected to the top of the room frame 2, ensuring the stability of the assembly and installation. The setting of the first drainage slope 48 and the second drainage slope 49 facilitates the drainage of rainwater and avoids Rainwater accumulates on the top surface of the roof 8; the walking platform 50 facilitates personnel movement; considering the stability when personnel first climb onto the roof 8, the safety handle 51 is easy for personnel to grip, making it convenient and safe to climb onto the top surface of the roof 8; the steel wire rope 53 is tightened using locking screw buckles and rope clamps 55, making it easy for people to fasten safety belts and attach ropes when walking on the roof 8, thus enhancing the safety of personnel on the roof; the installation of several hanging rings 56 facilitates the disassembly and installation of the roof 8; the installation of several fixed feet 57 facilitates the fixing of the roof 8 to the building frame 2.

[0090] The outer side of the top cover 8 is also provided with a drainage trough 58. The drainage trough 58 is higher inside and lower outside. The bottom of the drainage trough 58 is sealed with a drainage pipe 59. The end of the drainage pipe 59 away from the drainage trough 58 is sealed with a drainage hole 40. The drainage pipe 59 is located inside the square steel frame of the house frame 2. The drainage trough 58 is higher inside and lower outside to prevent rainwater from overflowing. The first drainage slope 48 and the second drainage slope 49 accelerate drainage. Rainwater is discharged into the drainage trough 58 and discharged from the drainage hole 40 through the drainage pipe 59 in the drainage trough 58, and is discharged to both sides of the house, effectively reducing water accumulation and erosion.

[0091] See Figures 1-12 The maintenance door 11 on the left side of the electrical room is equipped with several first louvers 60, and the corrugated plate 9 on the front side of the electrical room 3 is also equipped with a cold air fan 61.

[0092] The 10kV substation transformer room 19 has several second louvers 62 on its switch door 26. The inner side of the second louvers 62 located above the switch door 26 of the 10kV substation transformer room 19 is equipped with an integrated dustproof and heat dissipation structure 63.

[0093] The integrated dustproof and heat dissipation structure 63 has a filter mesh groove 64, with a filter mesh 65 embedded inside. A fan plate 66 is sealed to the outside of the filter mesh 65. A through hole 67 is opened in the center of the fan plate 66, and an axial flow fan 68 is installed on the through hole 67 of the fan plate 66. Several first louvers 60 can maintain the stability of indoor temperature and air circulation under normal conditions. The air cooler 61 can cool the room during operation to ensure heat dissipation of the switchgear. Finally, for the 10kV substation transformer room 19, which is the main heat-generating part, according to the principle that cold air sinks and hot air rises, the integrated dustproof and heat dissipation structure 63 is installed behind the second louver 62 above the switch door 26 of the 10kV substation transformer room 19. The integrated dustproof and heat dissipation structure 63 can not only accelerate the heat dissipation, but also greatly improve the space utilization rate. The above design solves the problems of untimely indoor heat dissipation, poor operation of electrical equipment, and damage.

[0094] See Figures 1-12 Waterproof eaves 69 are provided above the switch doors 26 of the 10kV substation transformer room 19, 10kV wiring room 20, 10kV connection room 21, 35kV wiring room 22, 35kV connection room 23 and 35kV transfer room 24. The angle between the waterproof eaves 69 and the door gap is 73°.

[0095] U-shaped waterproof frames 70 are installed between the inner sides of the switch doors 26 of the 10kV substation transformer room 19, 10kV wiring room 20, 10kV connection room 21, 35kV wiring room 22, 35kV connection room 23, and 35kV transfer room 24 and the corresponding building frame 2. One wing of the U-shaped waterproof frame 70 is fixedly connected to the building frame 2, and the other wing of the U-shaped waterproof frame 70 is clamped with a rubber strip 71. The inner sides of the switch doors 26 of the 10kV substation transformer room 19, 10kV wiring room 20, 10kV connection room 21, 35kV wiring room 22, 35kV connection room 23, and 35kV transfer room 24 abut against the rubber strip 71. Waterproof eaves 69 are provided. The design ensures that rainwater does not easily intrude above the switch doors 26 of the 10kV substation transformer room 19, 10kV wiring room 20, 10kV connection room 21, 35kV wiring room 22, 35kV connection room 23, and 35kV transfer room 24, keeping the electrical room 3 dry and preventing moisture from entering and damaging the electrical equipment. Furthermore, the rubber strip 71 secured by the U-shaped waterproof frame 70 ensures that the switch doors 26 of the 10kV substation transformer room 19, 10kV wiring room 20, 10kV connection room 21, 35kV wiring room 22, 35kV connection room 23, and 35kV transfer room 24 are sealed when closed, further preventing moisture from entering the electrical room 3.

[0096] See Figures 1-12 An alarm storage device 72 is also provided on the corrugated plate 9 at the end of the electrical room 3 away from the transformer room 4. The alarm storage device 72 is embedded inside the electrical room 3.

[0097] The alarm storage device 72 has a built-in storage box 73, and the built-in storage box 73 is equipped with an alarm device 74. The built-in storage box 73 is fixedly connected to the corrugated plate 9 at the end of the electrical room 3 away from the transformer room 4.

[0098] The alarm device 74 has a first mounting plate 75 and a second mounting plate 76, which are respectively installed on the bottom sides of the built-in storage box 73;

[0099] The first mounting plate 75 and the second mounting plate 76 are respectively detachably connected to the first slide side plate 77 and the second slide side plate 78 on opposite sides. The first slide side plate 77 and the second slide side plate 78 are provided with symmetrically distributed flip slides 79, storage pin holes 80, external pin holes 81 and fixing holes 82.

[0100] A flip-top plate 83 is provided between the first slide side plate 77 and the second slide side plate 78. A fixing block 84 and a sliding block 85 are provided on both sides of the flip-top plate 83. The flip-top plate 83 is rotatably connected to the fixing hole 82 through the fixing block 84, and the sliding block 85 is slidably embedded into the flip-top slide 79.

[0101] A movable pin 86 and an audible and visual alarm 87 are fixedly connected to the top surface of the flip-up base plate 83. One end of the movable pin 86 is inserted into the storage pin hole 80 or the external pin hole 81. The flip-up base plate 83 is fixed to the fixing hole 82 by the fixing block 84, and the other end slides on the flip slide rail 79 by the sliding block 85 of the flip-up base plate 83, so that the flip-up base plate 83 can be flipped, thereby realizing the storage of the audible and visual alarm 87. After the travel is in place, the movable pin 86 is inserted into the storage pin hole 80 or the external pin hole 81. To lock the substation, when the substation is in use, pull out the movable pin 86 and flip the base plate 83 to a vertical position via the flip slide 79, exposing the audible and visual alarm 87. At this time, lock the movable pin 86 into the external pin hole 81. Before the substation is hoisted and transported, pull out the movable pin 86 again and flip the base plate 83 to a horizontal position via the flip slide 79, hiding the audible and visual alarm 87 inside the built-in storage box 73. At this time, lock the movable pin 86 into the storage pin hole 80.

[0102] See Figures 1-12A hollow semi-circular foam sealing strip 88 is sandwiched between the inner side plate of the top cover 8 and the drainage channel 58. The back of the hollow semi-circular foam sealing strip 88 is attached to the top cover 8. The back of the hollow semi-circular foam sealing strip 88 has an adhesive surface, so it can be directly attached to the top cover 8. This ensures the airtightness between the top cover 8 and the drainage channel 58, effectively preventing rainwater from entering the electrical room 3, ensuring that the interior of the electrical room 3 is always dry, extending the service life of electrical equipment, and improving the waterproof and dustproof capabilities of the substation building.

[0103] Dust filters 89 (not shown in the figure) are installed behind several first louvers 60 and several second louvers 62. This can effectively prevent sand and dust from entering the electrical room 3, which is beneficial to protecting the electrical equipment inside the electrical room 3 and extending the service life of the electrical equipment inside the electrical room 3.

[0104] LED lights are installed on the inner wall of electrical room 3, and LED lighting 91 is installed on the outer wall of electrical room 3 and the inner wall of transformer room 4. The LED lights inside electrical room 3 can ensure sufficient illumination, which is convenient for maintenance and testing inside the enclosure. The LED lighting 91 outside electrical room 3 provides external lighting for the substation, which is convenient for staff to perform maintenance or open and close doors 26 outside the substation.

[0105] See Figures 1-12 In this embodiment, the transformer room 4 is designed to be open-air for the 35kV main transformer 15, and is surrounded by mesh doors to accelerate heat dissipation.

[0106] See Figures 1-12 In this embodiment, a skid-mounted substation building structure for fracturing mainly features reliable structure, complete functions, safe hoisting and maintenance, waterproof, dustproof, drainage, lighting and convenient use. In terms of structure, it adopts a design of reinforced base 1, building frame 2, first support 5, second support 6 and support frame 7.

[0107] In terms of functionality, the structure and layout have been rationally designed according to user needs;

[0108] In terms of hoisting, based on the change of center of gravity, the design adopts the first full-load hoisting point 32, the second full-load hoisting point 33, the third full-load hoisting point 34, the fourth full-load hoisting point 35, the first no-load hoisting point 36, and the second no-load hoisting point 37, and the corresponding hoisting rope limit block 42 is designed according to the hoisting position.

[0109] Regarding the top support, based on the first full-load lifting point 32, the second full-load lifting point 33, the third full-load lifting point 34, the fourth full-load lifting point 35, the first no-load lifting point 36, the second no-load lifting point 37, and the hoisting rope trajectory, the substation added corresponding first supports 5, second supports 6, and support frames 7 to the top of the building frame 2. These supports bear a large load during hoisting and effectively prevent the building frame 2 from deforming due to the hoisting rope squeezing it during hoisting.

[0110] In terms of maintenance safety, a relatively safe top cover 8 is designed, and there is a safety handle 51 above the escalator 25. There is a steel wire rope 53 with safety belt buckles around the middle walking platform 50 of the top cover 8.

[0111] In terms of drainage, a design of drainage channel 58, first drainage slope 48 and second drainage slope 492° slope and concealed drainage pipe 59 is adopted to avoid rainwater accumulation and damage to drainage pipe 59 by collision.

[0112] For waterproofing and dustproofing, an inclined top cover 8, waterproof eaves 69, and U-shaped waterproof frame 70 are used to prevent rainwater accumulation. The U-shaped waterproof frame 70, together with the rubber strip 71, can prevent dust and moisture from entering the electrical room 3.

[0113] In terms of heat dissipation, several first louvers 60, several second louvers 62, an embedded air cooler 61, and an axial fan 68 are designed to effectively reduce the indoor temperature and ensure the circulation of indoor air; a sliding alarm storage device 72 is adopted to avoid damage to the exposed sound and light alarm 87 from collisions.

[0114] See Figures 1-12In this embodiment, the longitudinal beams 29 and transverse beams 28 of the base 1 are reinforced and densified. Furthermore, based on the actual site conditions, designs such as traction lugs 38, grounding copper busbars 39, thermal insulation layers, drainage holes 40, and wiring holes 30 are incorporated. The building frame 2 is reinforced to address differences in load-bearing capacity, stress points on the top frame, and electrical clearances. The roof 8 is designed with a ladder 25, safety handles 51, a walking platform 50, wire ropes 53, hanging rings 56, and fixed feet 57 to improve the safety and convenience of maintenance and user personnel. The first drainage slope 48 and the second drainage slope 49 are used at varying angles to accelerate drainage. Water is collected in the drainage trough 58 and then discharged through a hidden... The drainage pipe 59 discharges water, reducing water erosion; the design of waterproof eaves 69, U-shaped waterproof frame 70 and rubber strips 71 achieves waterproof and dustproof sealing, and the electrical room 3 and transformer room are isolated to achieve dry and wet separation; some of the opening and closing doors 26 adopt a louver design, and most of the heat in the room is dissipated through the air cooler 61. In addition, a dustproof and heat dissipation integrated structure 63 is designed for the main heat-generating parts to accelerate heat dissipation. The first slide side plate 77 and the second slide side plate 78 of the audible and visual alarm 87 are designed with a flip slide 79, which can slide and hide or extend the audible and visual alarm 87 according to the usage scenario to avoid exposure and collision damage.

[0115] See Figures 1-12 In this embodiment, the building is unloaded and has low load-bearing capacity when the 35kV transformer is not installed, so a simple "I"-shaped first support 5 is used. After the transformer is assembled, the building is fully loaded, but the electrical room 3 is relatively light, so the "I"-shaped first support 5 is reinforced and a second support 6 is designed. Under the fully loaded state after the transformer is assembled, the 35kV main transformer 15 room is heavier, and the simple support design will interfere with the transformer terminals, failing to guarantee the electrical clearance of the transformer terminals. Therefore, in response to local heavy loads and electrical clearance, the load-bearing and spatial design of the support beam is further strengthened, and a hollow support frame 7 is creatively designed, which not only ensures structural strength but also leaves enough space for the transformer terminals, ensuring sufficient electrical clearance.

[0116] See Figures 1-12In this embodiment, during operation, the 35kV power supply is connected to the 35kV wiring room 23, and then connected to the 35kV switchgear room 18 via a transfer. The output line of the 35kV switchgear room 18 is connected to the high-voltage side of the 35kV main transformer 15. The low-voltage side of the main transformer outputs 10kV and connects to the 10kV wiring room 21. At the same time, a 10kV line is split off and connected to the high-voltage side of the station service transformer. The low-voltage side of the station service transformer outputs 400V and enters the low-voltage switchgear room 16. The low-voltage switchgear room 16 supplies power to the auxiliary electrical equipment of the substation. Its layout design fully considers the high and low voltage power needs, meets the functional requirements of the fracturing substation, and a smoke detector (not shown in the figure) is installed inside the substation building. At the same time, an audible and visual alarm 87 is installed outside the building to enhance the safety protection of the equipment.

[0117] See Figures 1-12 In this embodiment, the load-bearing properties and functions of the substation base 1 are comprehensively considered, and a base 1 with reliable strength and complete functions is designed, solving the problems of safety and practicality. The support frame 7 is creatively designed, which not only strengthens the overall strength of the substation frame 2 and improves hoisting safety, but also effectively solves the problem of electrical clearance limitation at the transformer connection. The substation roof 8 is designed with safety in mind, improving the safety of personnel in the use and maintenance of the substation. The drainage design of the substation is further improved, and the drainage pipe 59 is designed to be hidden while ensuring water collection and drainage functions. The integrated dustproof and heat dissipation structure 63 is creatively designed, which meets the requirements of dustproof ventilation, and achieves the purpose of convenient replacement and smaller size. The alarm storage device 72 is creatively designed, which solves the problem of exposed collision damage to the audible and visual alarm 87.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
