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 switchgear, transformers, control and protection devices, and other electrical equipment within one or more prefabricated cabins. This modularizes, standardizes, and prefabricates the substation, facilitating production, installation, and construction. Existing prefabricated cabins, due to their high internal structural integration, have limited space available, resulting in higher heat dissipation requirements for electrical equipment during operation.

[0003] In the prior art, a fan is used to exchange the hot air in the prefabricated cabin with the outside air to dissipate the heat inside the prefabricated cabin. In this method, the electrical equipment cannot be lifted and rotated, and the bottom of the electrical equipment and the sides close to the adjacent electrical equipment are subjected to targeted heat dissipation, which reduces the heat dissipation effect of the electrical equipment and affects the operating efficiency of the electrical equipment. A movable side wall frame is used to cover and protect the internal electrical components or completely expose them. In this method, multiple electrical equipment cannot be moved and rotated. Since multiple electrical equipment are installed closely, the maintenance space is small, which makes it inconvenient to repair the electrical equipment. Summary of the Invention

DETAILED DESCRIPTION

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

[0038] Reference Figures 1-3 A modular prefabricated cabin substation, comprising a prefabricated cabin, the prefabricated cabin being provided with air conditioners 6 on both sides, further comprising:

[0039] ​The prefabricated cabin includes two, the two prefabricated cabins are connected in the vertical direction, the lower prefabricated cabin is the first prefabricated cabin 1, the upper prefabricated cabin is the second prefabricated cabin 3, the outer side of the joint of the first prefabricated cabin 1 and the second prefabricated cabin 3 is fixedly connected with a baffle 2, the top of the second prefabricated cabin 3 is fixedly connected with a shielding plate 4, the first prefabricated cabin 1 and the second prefabricated cabin 3 are both provided with a cabin door 8, and both sides are provided with a ventilation opening 5.

[0040] The top of the first prefabricated cabin 1 is in a convex structure, the bottom of the second prefabricated cabin 3 is in a concave structure, and the convex structure and the concave structure are connected in a snap-fit manner.

[0041] When the staff hoists and places the second prefabricated cabin 3 on the first prefabricated cabin 1, the concave structure and the convex structure are connected in a snap-fit manner, this nested structure can significantly improve the stability of the prefabricated cabin when stacked, and the convex and concave structures and the baffle 2 cooperate to form a transverse limit, increasing the horizontal constraint, preventing the upper and lower cabin bodies from sliding relative to each other, the convex structure can directly bear the transverse force from the concave structure, rather than relying on the external connecting structure to bear the force, making the vertical gravity distribution more uniform, this interlocking structure can avoid layer misalignment during an earthquake, reducing the risk of overturning.

[0042] The top of the convex structure is fixedly connected with a positioning block 25, the step is fixedly connected with a positioning pin 9, the concave structure is provided with a positioning groove connected with the positioning block 25 in a snap-fit manner and a pin hole connected with the positioning pin 9 in a pin connection manner, the concave structure is slidably connected with a first wedge block 10 and a second wedge block 11, the first wedge block 10 is located above the pin hole, the wedge-shaped end of the first wedge block 10 is close to the convex structure and abuts against the wedge-shaped end of the second wedge block 11, and the second wedge block 11 is fixedly connected with a spring 13 between the concave structure.

[0043] Through the cooperation of the positioning block 25 and the positioning groove, the second prefabricated cabin 3 can be quickly positioned, the manual adjustment time during hoisting is reduced, the alignment of the cabin body in the horizontal and vertical directions is ensured, and the installation efficiency is improved.

[0044] When the second prefabricated cabin 3 is placed in the first prefabricated cabin 1, the positioning pin 9 of the first prefabricated cabin 1 will push the first wedge block 10 to move upward after entering the inside of the second prefabricated cabin 3, when the first wedge block 10 moves upward, the wedge-shaped end thereof pushes the second wedge block 11 to move horizontally, the second wedge block 11 generates extrusion force on the contact surface of the first prefabricated cabin 1, thereby pushing the second wedge block 11 to complete clamping on the first prefabricated cabin 1, realizing horizontal self-locking.

[0045] The convex structure and the concave structure are fixedly connected with a rubber pad 12, and 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 when the first prefabricated cabin 1 and the second prefabricated cabin 3 vibrate, and maintain the stability of the entire prefabricated cabin.

[0047] When the second prefabricated cabin 3 is placed on the first prefabricated cabin 1, clamping is completed by the self-weight of the upper cabin body, and the operator does not need to exert additional force.

[0056] The wire wound on the roller 50 penetrates the shaft cavity of the roller 50 and is electrically connected with the external power supply system through the cable. When the installation shell 33 moves upward, the wire wound on the roller 50 is released and elongated, thereby ensuring the electrical connection of the electrical equipment 17.

[0059] The first flow guide plate 20 is a telescopic structure, the fixed end of the first flow guide plate 20 is fixedly connected with the connecting rod, the telescopic end is fixedly connected with a connecting piece 42, the top of the connecting piece 42 is rotatably connected with a fixed rod 43, the top of the fixed rod 43 is fixedly connected with a fixed plate 44, and the fixed plate 44 is fixedly connected on the mounting shell 33.

[0060] The ventilation mechanism further comprises a fan 34 installed on the top of the moving base 19, the bottom of the mounting shell 33 is provided with a containing groove for containing the fan 34, 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 with a second flow guide plate 26, a plurality of air holes are formed in the second flow guide plate 26, and the axial direction of the second motor 28 is perpendicular to the ventilation direction of the air conditioner 6.

[0061] With reference to Figure 11 A plurality of fixed frames 15 are fixedly connected to the top of the prefabricated cabin, the plurality of fixed frames 15 correspond to the plurality of electrical equipment 17 one by one, a limiting frame 47 is fixedly connected to the inner side of the fixed frame 15, a clamping head 48 is installed on the inner side of the limiting frame 47, and the output end of the clamping head 48 is in extrusion fit with the electrical equipment 17 that is moved into the limiting frame 47.

[0062] The clamping head 48 adopts the prior art, and the clamping block is pushed by an electric push rod to extrude and clamp the side of the electrical equipment 17.

[0063] With reference to Figures 4-6 Two movable electric arc baffles 16 are fixedly connected to the top of the prefabricated cabin, the two electric arc baffles 16 are moved to isolate the electrical equipment 17 below from other electrical equipment 17, a carbon dioxide fire extinguisher 14 is installed on the top of the prefabricated cabin, the air injection end of the carbon dioxide fire extinguisher 14 is installed on the electric arc baffle 16, and the air injection direction of the carbon dioxide fire extinguisher 14 points to the isolated electrical equipment 17.

[0064] The electric arc baffle 16 is controlled to move through the existing controllable telescopic mechanism, so that the electric arc baffle 16 can conveniently isolate the electrical equipment 17 that fails.

[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, and the driving mechanism, the hydraulic rod 35 and the thermal imaging probe 27 are electrically connected with the controller.

[0066] When the air conditioner 6 is used, the air conditioner 6 normally works, so that the inside of the prefabricated cabin is kept in normal airflow circulation.

[0067] When the temperature of the electrical equipment 17 detected by the thermal imaging probe 27 is greater than 60℃, the controller receives the signal of the thermal imaging probe 27 and starts the hydraulic rod 35, the output end of which is extended to lift the mounting shell 33, increase the distance between the mounting shell 33 and the moving base 19, and increase the ventilation space therebetween, so as to facilitate the airflow to pass through the ventilation space and improve the heat dissipation effect on the bottom of the electrical equipment 17.

[0068] In the process of lifting the mounting shell 33, the first rack 37 moves upward together with the mounting shell 33, thereby driving the connecting rod to rotate through the fourth gear 46, the first bevel gear 41 and the second bevel gear 45, and the first guide plate 20 is rotated by the connecting rod. At the same time, the mounting shell 33 also drives the fixed plate 44 to rise in the process of lifting, so as to pull out the telescopic part of the first guide plate 20 through the fixed rod 43 and the connecting piece 42, increase the height of the first guide plate 20, cover more heating areas, and form a horn shape on both sides of the moving base 19 after the four first guide plates 20 are rotated, so as to make the airflow circulating in the prefabricated cabin converge to the inside of the ventilation space, and enhance the ventilation and heat dissipation effect on the bottom of the electrical equipment 17.

[0069] In the process of lifting the mounting shell 33, the ventilation space is continuously increased, and the first guide plate 20 is continuously rotated. In the process of rotating the first guide plate 20, the two first guide plates 20 on the same side are continuously closed, and the fluid passage area between them is continuously reduced, so as to increase the fluid velocity and enhance the heat dissipation effect of the airflow in the ventilation space.

[0070] After the mounting shell 33 is lifted, the fan 34 on the moving base 19 is exposed, the fan 34 is started, and the fan 34 can significantly improve the airflow circulation efficiency in the ventilation space through forced convection.

[0071] Moreover, in the flood natural disaster, the hydraulic rod 35 works to drive the mounting shell 33 and the electrical equipment 17 to move upward, which can effectively avoid the electrical equipment 17 from being flooded and protect the electrical equipment 17.

[0072] When the electrical equipment 17 rises to a certain height and enters the limiting frame 47, the clamping head 48 works, the output end of which is extended to limit and clamp the electrical equipment 17, so as to ensure that the electrical equipment 17 can withstand external force during the flood period and improve the ability to resist external force.

[0073] When the thermal imaging probe 27 detects that the temperature of the opposite side of the two adjacent electrical equipment 17 is greater than 60℃, the third motor 49 is started to drive the electrical equipment 17 to rotate through the first gear 31 and the second gear 32, so that the heat generating part of the electrical equipment 17 is rotated to the passageway between the electrical equipment 17 and the prefabricated cabin, where the airflow flows most smoothly, thereby increasing the heat dissipation effect of the heat generating part of the electrical equipment 17.

[0074] At the same time, the corresponding second motor 28 is started, and the second motor 28 works, and the output end drives the second guide plate 26 to rotate, so that the airflow blows to the heat generating part of the electrical equipment 17, thereby improving the heat dissipation effect.

[0075] The second motor 28 has a plurality of air holes, and the air holes allow the airflow on both sides to pass through, which does not affect the normal airflow circulation, and forms a more complex airflow path through the air holes, which helps to break the thermal boundary layer and promote the exhaust of hot air and the intake of cold air.

[0076] In addition, in daily use, the direction of the electrical equipment 17 can be adjusted by rotating the angle of the electrical equipment 17 according to the direction of solar radiation and the airflow, and in summer, the electrical equipment 17 is arranged to face away from the direct sunlight, which can effectively reduce the influence of solar radiation heat, thereby reducing the operating temperature of the electrical equipment 17, reducing the load of the air conditioner 6, and improving the operating efficiency of the electrical equipment 17; in winter, the electrical equipment 17 is arranged to face the sunlight, which can use the solar radiation heat to increase the temperature of the operating environment of the electrical equipment 17, thereby reducing the heating demand.

[0077] In addition, by rotating the electrical equipment 17, the part to be repaired can be turned to the operable space, so that the problem of being unable to repair due to narrow space can be avoided.

[0078] When the installation shell 33 is lifted and lowered, the second rack 38 drives the roller 50 to rotate through the third gear 40, so that the wire can always maintain a proper tension state during the movement of the electrical equipment 17, thereby avoiding winding, knotting or excessive pulling of the electrical equipment 17, and thereby ensuring the stability of the electrical connection.

[0079] When the electrical equipment 17 overheats or even sparks due to failure, the driving mechanism works to move the faulty electrical equipment 17 below the two arc baffles 16 and move other electrical equipment 17 away, and then lower the arc baffle 16 to isolate the faulty electrical equipment 17, and in the process of lowering the arc baffle 16, the carbon dioxide extinguisher 14 works to extinguish the faulty electrical equipment 17, thereby preventing the influence on the adjacent electrical equipment 17.

[0080] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
