Description

Technical Field

[0001] The present invention relates to the technical field of substations, and in particular to a modular prefabricated cabin substation. Background Art

[0002] A prefabricated cabin substation is a new type of substation equipment that integrates high-voltage switch cabinets, transformers, control and protection devices, and other electrical equipment in one or more prefabricated cabins, realizing the modularization, standardization, and prefabrication of substations, which is convenient for production, installation, and construction. In the existing prefabricated cabins, due to the high integration degree of the internal structure, the overall reserved space is small, and when the electrical equipment is working, its heat dissipation requirement is higher.

[0003] In the prior art, a fan is used to exchange the hot air in the prefabricated cabin with the outside air to dissipate heat from the inside of the prefabricated cabin. In this way, the electrical equipment cannot be lifted and rotated, and targeted heat dissipation cannot be carried out on the bottom of the electrical equipment and the side close to the adjacent electrical equipment, reducing the heat dissipation effect on the electrical equipment and affecting the operation efficiency of the electrical equipment; a movable side wall frame is used to wrap and protect or completely expose the internal electrical components. In this way, multiple electrical equipment cannot be moved and rotated, and due to the close installation of multiple electrical equipment, the maintenance space is small, which is not convenient for maintaining the electrical equipment.

[0021] Compared with the existing technology, the advantages of the present invention are as follows:

[0022] 1. The present invention increases the ventilation space between the installation housing and the moving base by setting up a ventilation mechanism. When the output end of the hydraulic rod extends, the installation housing is lifted, facilitating the flow of air through the ventilation space. Meanwhile, the first deflector is driven to rotate by a gear transmission structure, guiding and squeezing the air flowing between the two first deflectors, increasing the speed of the air flowing into the ventilation space, and improving the heat dissipation effect at the bottom of the electrical equipment. Lifting the installation housing can also increase the height of the electrical equipment, effectively preventing the electrical equipment from being flooded.

[0023] 2. The present invention sets up a driving mechanism. When the first motor operates, the sliding block is driven to move by the lead screw. The sliding block drives the moving base to move through the electromagnet, thereby driving the electrical equipment on the moving base. The layout of multiple electrical equipment can be flexibly adjusted according to actual needs, enhancing the adaptability to complex environments. The electrical equipment can also be easily moved to an area convenient for maintenance, avoiding the disassembly of fixing devices and reducing maintenance time and labor costs. In cooperation with the movable arc baffle and carbon dioxide fire extinguisher, the faulty electrical equipment can be isolated and extinguished, effectively preventing the impact on adjacent electrical equipment.

[0024] 3. The present invention rotatably mounts the electrical equipment on the bottom plate. By rotating the electrical equipment, the heat-generating part on its side can be rotated to the air flow passage, increasing the heat dissipation effect of the electrical equipment. According to the solar radiation direction and air flow conditions, the angle of the electrical equipment can be changed to reduce the load on the air conditioner and improve the operating efficiency of the electrical equipment. By rotating the electrical equipment, the part to be repaired can be turned to the operable space, avoiding the problem of being unable to repair due to narrow space.

Detailed implementation manners

[0037] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0038] Referring to Figures 1 - 3 , a modular prefabricated cabin substation includes a prefabricated cabin, and air conditioners 6 are installed on both sides of the prefabricated cabin. It further includes:

[0039] There are two prefabricated cabins, which are clamped and matched in the vertical direction. The prefabricated cabin located below is the first prefabricated cabin 1, and the prefabricated cabin located above is the second prefabricated cabin 3. A baffle 2 is fixedly connected to the outside of the clamping joint between the first prefabricated cabin 1 and the second prefabricated cabin 3. A shielding baffle 4 is fixedly connected to the top of the second prefabricated cabin 3. Cabin doors 8 are installed on both the first prefabricated cabin 1 and the second prefabricated cabin 3, and ventilation openings 5 are provided on both sides.

[0040] The top of the first prefabricated cabin 1 has a convex structure, and the bottom of the second prefabricated cabin 3 has a concave structure. The convex structure and the concave structure are clamped and matched.

[0041] When the staff hoist and place the second prefabricated cabin 3 on the first prefabricated cabin 1, through the clamping and matching of the concave structure and the convex structure, this nested structure can significantly improve the stability of the prefabricated cabins when stacked. Moreover, the convex and concave structures and the baffle 2 cooperate to form a lateral limit, increasing the restraint in the horizontal direction and preventing the relative sliding of the upper and lower cabin bodies. The convex structure can directly bear the lateral force from the concave structure, rather than relying solely on the external connection structure to bear the force, making the gravity distribution in the vertical direction more uniform. This interlocking structure can avoid interlayer dislocation during an earthquake and reduce the risk of overturning.

[0042] A positioning block 25 is fixedly connected to the top of the convex structure, and a positioning pin 9 is fixedly connected to the step. A positioning groove for clamping and matching with the positioning block 25 and a pin hole for pin connection and matching with the positioning pin 9 are provided on the concave structure. A first wedge block 10 and a second wedge block 11 are slidably connected to the concave structure. The first wedge block 10 is located above the pin hole. The wedge end of the first wedge block 10 is close to the convex structure and abuts against the wedge end of the second wedge block 11. A spring 13 is fixedly connected between the second wedge block 11 and the concave structure.

[0043] Through the cooperation of the positioning block 25 and the positioning groove, the rapid positioning of the second prefabricated cabin 3 can be realized, reducing the manual adjustment time during the hoisting process, ensuring the alignment of the cabin body in the horizontal and vertical directions, and improving the installation efficiency.

[0044] When the second prefabricated cabin 3 is placed on the first prefabricated cabin 1, after the positioning pin 9 of the first prefabricated cabin 1 enters the interior of the second prefabricated cabin 3, it will push the first wedge block 10 upward. When the first wedge block 10 moves upward, its wedge end pushes the second wedge block 11 to move horizontally. The contact surface between the second wedge block 11 and the first prefabricated cabin 1 generates a squeezing force, thereby pushing the second wedge block 11 to clamp the first prefabricated cabin 1 and realizing self-locking in the horizontal direction.

[0045] A rubber pad 12 is fixedly connected between the convex structure and the concave structure. The side of the second wedge block 11 away from the spring 13 abuts against the rubber pad 12.

[0046] The rubber pad 12 can absorb the energy generated during the vibration of the first prefabricated cabin 1 and the second prefabricated cabin 3, maintaining the stability of the entire prefabricated cabin.

[0047] When placing the second prefabricated cabin 3 on the first prefabricated cabin 1, the self-weight of the upper cabin is utilized to complete the clamping, eliminating the need for additional force from the operator. Additionally, the structures used for clamping are all located inside the cabin, without occupying external space and saving site area.

[0048] Refer to Figures 4 - 6 , the driving mechanism, which is connected inside the prefabricated cabin.

[0049] The moving bases 19, multiple moving bases 19 are all slidably connected to the inner bottom of the prefabricated cabin and are connected to the output end of the driving mechanism through magnetic action.

[0050] The driving mechanism includes a first motor 7 installed at the bottom of the prefabricated cabin. The output end of the first motor 7 penetrates the prefabricated cabin in a sealed manner and is coaxially and fixedly connected to a lead screw 23. A sliding block 22 is threadedly connected to the lead screw 23. A limiting rod 24 is slidably connected through the inside of the sliding block 22, and an electromagnet 29 is installed on the side. The limiting rod 24 is fixedly connected to the inner bottom of the prefabricated cabin. Ferromagnetic blocks are embedded inside multiple moving bases 19, and when the electromagnet 29 is energized, it magnetically attracts one ferromagnetic block.

[0051] When the first motor 7 operates, its output end drives the sliding block 22 to move through the lead screw 23. When the sliding block 22 moves to the corresponding moving base 19, the electromagnet 29 is activated. After the electromagnet 29 is energized, it magnetically attracts the ferromagnetic block inside the moving base 19. The first motor 7 continues to operate, thereby driving the moving base 19 to move, and further driving the electrical equipment 17 on the moving base 19 to move. The layout of multiple electrical equipment 17 can be flexibly adjusted according to actual needs, enhancing the adaptability to complex environments. Additionally, the electrical equipment 17 can be easily moved to an area convenient for maintenance, avoiding the disassembly of fixing devices and reducing maintenance time and labor costs.

[0052] Multiple electric telescopic rods are installed at the bottom of the moving base 19. The output end of the electric telescopic rod is rotatably connected to a roller 39. When the output end of the electric telescopic rod extends, the roller 39 abuts against the inner bottom of the prefabricated cabin. Two support rods 21 penetrate and are slidably connected to multiple moving bases 19, and both support rods 21 are fixedly connected to the inner bottom of the prefabricated cabin.

[0053] When the moving base 19 moves, the electric telescopic rod operates, and its output end extends to lower the roller 39. The roller 39 abuts against the inner bottom of the prefabricated cabin to assist the moving base 19 in moving. When the moving base 19 does not move, the roller 39 can be retracted to ensure the stability of the moving base 19.

[0054] Refer to Figures 7 - 10, a bottom plate 18 is fixedly connected to the top of the installation housing 33. A third motor 49 is installed on the top of the bottom plate 18. The output end of the third motor 49 is coaxially and fixedly connected to a first gear 31. A second gear 32 is meshed with the side of the first gear 31. The top end of the second gear 32 is fixedly connected to the bottom of the electrical equipment 17. The electrical equipment 17 is rotatably connected to the top of the bottom plate 18.

[0055] Referring to Figures 7 - 9 , a slip ring 30 is installed at the bottom of the electrical equipment 17. A third gear 40 is rotatably connected inside the moving base 19. A second rack 38 is fixedly connected to the bottom of the installation housing 33. The bottom end of the second rack 38 penetrates through the moving base 19 and meshes with the third gear 40. The third gear 40 is coaxially fixedly connected to a roller 50. The second gear 32 is annular. The slip ring 30 is electrically connected to a wire. One end of the wire away from the slip ring 30 passes through the inside of the annular second gear 32, penetrates through the bottom plate 18, the installation housing 33 and the moving base 19, and is wound around the roller 50.

[0056] The wire wound around the roller 50 passes through the shaft cavity of the roller 50 and is electrically connected to the external power supply system through a cable. When the installation housing 33 moves upward, the wire wound around the roller 50 is released and elongated accordingly, ensuring the electrical connection of the electrical equipment 17.

[0057] Referring to Figures 7 - 10 , a ventilation mechanism. The ventilation mechanism includes a hydraulic rod 35 installed on the top of the moving base 19. The output end of the hydraulic rod 35 is fixedly connected to the installation housing 33. The electrical equipment 17 is rotatably installed on the top of the installation housing 33. Four gear transmission structures are connected between the installation housing 33 and the moving base 19. The output end of the gear transmission structure is connected to a first deflector 20. The four first deflectors 20 are respectively located at the four corners of the moving base 19.

[0058] The gear transmission structure includes four first racks 37 fixedly connected to the bottom of the installation housing 33. A fourth gear 46 is meshed with the side of the first rack 37. The fourth gear 46 is rotatably connected inside the moving base 19 and is coaxially fixedly connected to a first bevel gear 41 through a connecting shaft penetrating through the moving base 19. The first bevel gear 41 meshes with a second bevel gear 45. The second bevel gear 45 is coaxially fixedly connected to a connecting rod. The connecting rod is rotatably connected to a fixed housing 36. The fixed housing 36 is fixedly connected to the corner of the moving base 19. Both ends of the connecting rod penetrate through the fixed housing 36 and are fixedly connected to the same first deflector 20. The axial direction of the connecting rod is perpendicular to the ventilation direction of the air conditioner 6. The first bevel gear 41 and the second bevel gear 45 are both located inside the fixed housing 36.

[0059] The first deflector 20 is a telescopic structure. The fixed end of the first deflector 20 is fixedly connected to the connecting rod, and the telescopic end is fixedly connected to a connecting member 42. The top of the connecting member 42 is rotatably connected to a fixed rod 43, and the top of the fixed rod 43 is fixedly connected to a fixing plate 44, and the fixing plate 44 is fixedly connected to the installation housing 33.

[0060] The ventilation mechanism further includes a fan 34 installed on the top of the mobile base 19. A receiving groove for accommodating the fan 34 is provided at the bottom of the installation housing 33. A plurality of second motors 28 are installed on the inner side of the prefabricated cabin. The output end of the second motor 28 is fixedly connected to a second deflector 26. A plurality of ventilation holes are provided on the second deflector 26. The axial direction of the second motor 28 is perpendicular to the ventilation direction of the air conditioner 6.

[0061] Refer to Figure 11 , a plurality of fixing frames 15 are fixedly connected to the inner top of the prefabricated cabin. The plurality of fixing frames 15 correspond to the plurality of electrical devices 17 one by one. A limiting frame 47 is fixedly connected to the inner side of the fixing frame 15. A clamping head 48 is installed inside the limiting frame 47. The output end of the clamping head 48 is in pressing fit with the electrical device 17 that moves into the limiting frame 47.

[0062] The clamping head 48 adopts the existing technology and pushes the clamping block through an electric push rod to squeeze and clamp the side of the electrical device 17.

[0063] Refer to Figures 4 - 6 , two arc baffles 16 that can move are fixedly connected to the inner top of the prefabricated cabin. After the two arc baffles 16 move, the electrical device 17 below them is isolated from other electrical devices 17. A carbon dioxide fire extinguisher 14 is installed on the inner top of the prefabricated cabin. The jet end of the carbon dioxide fire extinguisher 14 is installed on the arc baffle 16, and its jet direction points to the isolated electrical device 17.

[0064] The movement of the arc baffle 16 is controlled by the existing controllable telescopic mechanism, which facilitates the isolation of the faulty electrical device 17 by the arc baffle 16.

[0065] A controller is installed on the prefabricated cabin. A plurality of thermal imaging probes 27 are installed on the inner side of the prefabricated cabin. The driving mechanism, the hydraulic rod 35, and the thermal imaging probes 27 are all electrically connected to the controller.

[0066] When the present invention is in use, the air conditioner 6 works normally to keep the normal air flow inside the prefabricated cabin.

[0067] When the electrical device 17 is continuously operating, when the thermal imaging probe 27 detects that the local temperature of the electrical device 17 is greater than 60 °C, the controller receives the signal from the thermal imaging probe 27 and activates the hydraulic rod 35. The output end of the hydraulic rod 35 extends, lifting the installation housing 33, increasing the distance between the installation housing 33 and the mobile base 19, enlarging the ventilation space therebetween, facilitating the flow of air through the ventilation space, and improving the heat dissipation effect on the bottom of the electrical device 17.

[0068] During the process of lifting the installation housing 33, the first rack 37 will move upward together with the installation housing 33. Thus, through the fourth gear 46, the first bevel gear 41, and the second bevel gear 45, the connecting rod is driven to rotate, and the connecting rod drives the first deflector 20 to rotate. At the same time, during the process of the installation housing 33 rising, it will also drive the fixing plate 44 to rise, thereby pulling out the telescopic part of the first deflector 20 through the fixing rod 43 and the connecting member 42, increasing the height of the first deflector 20 so that it covers more heat-generating areas. After the four first deflectors 20 rotate, a flared shape with an outward opening is formed on both sides of the mobile base 19, causing part of the air flow circulating in the prefabricated cabin to converge towards the interior of the ventilation space, enhancing the ventilation and heat dissipation effect on the bottom of the electrical device 17.

[0069] During the lifting process of the installation housing 33, the ventilation space continuously increases, and the first deflector 20 continuously rotates. During the rotation process of the first deflector 20, the two first deflectors 20 on the same side continuously close together, and the cross-sectional area of the fluid channel therebetween continuously decreases, thereby increasing the fluid velocity and enhancing the heat dissipation effect of the air flow on the ventilation space.

[0070] After the installation housing 33 is lifted, the fan 34 on the mobile base 19 is exposed. The fan 34 is activated, and when the fan 34 operates, the air flow circulation efficiency inside the ventilation space can be significantly improved through forced convection.

[0071] Moreover, in flood natural disasters, the hydraulic rod 35 operates to drive the installation housing 33 to drive the electrical device 17 to move upward, which can effectively prevent the electrical device 17 from being flooded and protect the electrical device 17.

[0072] When the electrical device 17 rises to a certain height and enters the limit frame 47, the clamping head 48 operates, and its output end extends to limit and clamp the electrical device 17, ensuring that it can withstand external forces during floods and improving its ability to resist external forces.

[0073] When the thermal imaging probe 27 detects that the temperature of the opposite faces of two adjacent electrical devices 17 is greater than 60°C, the third motor 49 starts, drives the electrical device 17 to rotate through the first gear 31 and the second gear 32, so that the heat-generating part of the electrical device 17 rotates to the aisle between the electrical device 17 and the prefabricated cabin, where the air flow is the smoothest, increasing the heat dissipation effect of the heat-generating part of the electrical device 17.

[0074] At the same time, the corresponding second motor 28 is started. The second motor 28 works, and its output end drives the second deflector 26 to rotate, guiding the air flow to blow towards the heat-generating part of the electrical device 17, improving the heat dissipation effect.

[0075] There are several ventilation holes on the second motor 28. The ventilation holes allow the air flow on both sides to pass through, which not only does not affect the normal air flow, but also forms a more complex air flow path through the ventilation holes, helping to break the thermal boundary layer and promoting the discharge of hot air and the intake of cold air.

[0076] In addition, during daily use, according to the solar radiation direction and air flow conditions, the orientation of the electrical device 17 can be adjusted by rotating the angle of the electrical device 17. In summer, turning the electrical device 17 away from the direct sunlight direction can effectively reduce the influence of solar radiation heat, thereby reducing the operating temperature of the electrical device 17, reducing the load of the air conditioner 6, and improving the operating efficiency of the electrical device 17; in winter, turning the electrical device 17 towards the sun can utilize the solar radiation heat to increase the temperature of the operating environment of the electrical device 17 and reduce the heating demand.

[0077] In addition, by rotating the electrical device 17, the part to be overhauled can be turned towards the operable space, avoiding the problem of being unable to overhaul due to narrow space.

[0078] When the installation housing 33 is lifted and lowered, the second rack 38 drives the roller 50 to rotate through the third gear 40, which can ensure that the wire always maintains an appropriate tension state during the movement of the electrical device 17, avoiding the electrical device 17 from being wound, knotted or over-pulled, thereby ensuring the stability of the electrical connection.

[0079] When the electrical device 17 fails and generates excessive heat or even sparks, the driving mechanism works, moves the faulty electrical device 17 under the two arc baffles 16, and moves the other electrical devices 17 away. Subsequently, the arc baffles 16 are lowered to isolate the faulty electrical device 17. During the process of lowering the arc baffles 16, the carbon dioxide fire extinguisher 14 works, which can extinguish the fire of the faulty electrical device 17 and prevent it from affecting the adjacent electrical devices 17.

[0080] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
