Description

Technical Field

[0001] This invention relates to the field of substation technology, and more specifically, to a mobile substation with rapid access. Background Technology

[0002] Substations are places in the power system that transform voltage and current, receive electrical energy, and distribute electrical energy. They play a crucial role in the operation of the power grid. The installation locations of existing substations are generally fixed and are fixed facilities of related projects. This means that if an accident occurs at a substation, the power supply will fail and the entire project will be shut down.

[0003] A search revealed that Chinese patent application CN118367465A discloses a mobile substation, comprising a controller, a platform, a substation body, a mover, two supporting devices, and two fixed devices. The mover is used to drive the substation body to move via the platform. The controller is electrically connected to the mover, the two supporting devices, and the two fixed devices. In this device, the mover moves the platform and the substation body via an external trailer, allowing the substation body to quickly enter a suspended project, ensuring the project continues normally and avoiding downtime. Chinese patent application CN219371806U discloses a mobile prefabricated substation, including a substation... The main body of the substation has a switchable door on its front, with a combination lock fixed to its outer surface. Ventilation openings are also present on the outer surface of the door. Shock-absorbing devices are installed at the four corners of the substation's base, with support housings fixedly connected to their bottoms. Casters are fixedly attached to the four corners of the lower surface of the support housings. These casters allow workers to easily move the prefabricated substation to the desired location, saving time and effort and solving the problem of traditional prefabricated substations requiring tools for transport. The shock-absorbing devices significantly reduce vibrations to the substation's main body, preventing damage to internal equipment and providing protection.

[0004] However, the above-mentioned devices still have certain shortcomings: 1. Existing substations are inconvenient for transformer maintenance. When a transformer malfunctions and needs repair, the side door or top cover of the cabinet must be disassembled first, and then the transformer must be lifted off the cabinet with the help of external hoisting equipment. The whole process is complicated and time-consuming, which not only prolongs the power outage time but also increases the maintenance cost; 2. During the operation of the substation, equipment such as transformers and switchgear will generate a lot of heat. If the heat dissipation is not timely, the temperature inside the cabinet will rise, which will lead to insulation aging, performance degradation, and even serious faults such as short circuits and burnout. Existing substations mostly use ventilation holes for natural heat dissipation, which is not very effective.

[0005] Therefore, we have made improvements to this by proposing a mobile substation with rapid access to solve the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to address the current problems of inconvenient transformer maintenance and poor heat dissipation.

Two slide rails are symmetrically and fixedly connected to the upper end face of the protruding plate. Sliding strips are slidably connected in both slide rails. An protruding frame is fixedly connected to the top of the second moving block and the sliding strips. An inner frame is fixedly connected in the protruding frame. The transformer is disposed between the inner frames and is fixedly connected to the protruding frame.

[0012] Furthermore, a rotating shaft is rotatably connected to the front ends of both side walls of the extended frame. A fixing sleeve is fixedly connected to the outer end of each rotating shaft. A first telescopic cylinder is fixedly connected inside the fixing sleeve. A first support seat is fixedly connected to the driving end of the first telescopic cylinder. A third bevel gear is fixedly connected to the inner end of the rotating shaft. Two support blocks are fixedly connected to the left and right inner side walls of the extended frame. A transmission rod is rotatably connected between two adjacent support blocks. A fourth bevel gear that meshes with the third bevel gear is fixedly connected to the front end of the transmission rod. A fifth bevel gear is fixedly connected to the rear end of the transmission rod. A connecting shaft is rotatably connected to the rear end of the extended frame. Two sixth bevel gears that mesh with the fifth bevel gear are fixedly connected to the connecting shaft. A worm gear is fixedly connected to the center of the connecting shaft. A second motor is fixedly connected to the rear side wall of the extended frame. The driving end of the second motor passes through the rear side wall of the extended frame and is fixedly connected to a worm that meshes with the worm gear.

[0013] Furthermore, the heat dissipation assembly includes a shield fixed to the top of the substation body. The front end of the shield has an installation port, and an assembly plate is slidably connected inside the installation port. Fixing ears are fixedly connected to both ends of the outer side wall of the assembly plate. The fixing ears are fixedly connected to the shield by bolts. Three cooling fans are evenly fixedly connected to the assembly plate. A handle is fixedly connected to the center of the outer side wall of the assembly plate.

[0014] Furthermore, three first circular holes corresponding to the positions of the cooling fans are evenly opened on the inner bottom wall of the shield, and a set of air inlets are evenly opened on the rear side wall of the shield.

[0015] Furthermore, the movable component includes a base frame fixed to the lower end face of the substation body, with rollers rotatably connected to the base frame, a trailer seat fixedly connected to the center of the right end of the base frame, and two fixed plates symmetrically connected to the left and right ends of the base frame, with a second telescopic cylinder fixedly connected to each fixed plate, the drive end of the second telescopic cylinder penetrating the fixed plate and fixedly connected to a second support base.

[0016] Furthermore, a controller and a temperature sensor are fixedly connected to the inner top wall of the substation body, and the controller is electrically connected to the temperature sensor and the cooling fan respectively.

[0017] Furthermore, the upper surface of the substation body is provided with three second circular holes corresponding to the positions of the cooling fans.

[0018] Furthermore, a set of heat dissipation holes are evenly spaced on the left and right side walls of the substation body.

[0019] Furthermore, the center of the front and rear side walls of the substation body is rotatably connected to a first sealing door via hinges, and the left and right ends of the front side of the substation body are rotatably connected to a second sealing door via hinges.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By setting up the removal support assembly, the transformer can be moved horizontally. The whole process does not require external hoisting equipment, the operation is highly automated, and after removal, the first telescopic cylinder drives the first support seat to form a stable support, ensuring the safety of maintenance operations. After maintenance is completed, the transformer can be quickly reset by reversing the process. This greatly simplifies the maintenance steps, shortens the maintenance time, and reduces the maintenance manpower and equipment costs, solving the problem of inconvenience in maintaining transformers in the existing technology.

[0022] 2. Through the design of heat dissipation components, controller, and temperature sensor, the cooling fan forms a directional airflow to improve heat dissipation efficiency. At the same time, the linkage design between the temperature sensor and the controller enables the cooling fan to start and stop automatically. This not only allows for rapid cooling when the temperature exceeds the limit, but also enables energy saving by stopping when the temperature is normal, avoiding ineffective energy consumption. It also facilitates the maintenance of the cooling fan and solves the problem of poor heat dissipation in existing technologies. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-9 This embodiment proposes a mobile substation for rapid access, including a substation body 1, a transformer 2 installed inside the substation body 1, and further including:

[0035] The support assembly 3 is located on the underside of the transformer 2 and is used to remove the transformer 2 for easy maintenance.

[0036] Heat dissipation component 4 is located at the top of substation body 1 and is used to dissipate heat from substation body 1.

[0037] The movable component 5 is located on the underside of the substation body 1 and is used to move the substation body 1.

[0038] The removal support assembly 3 includes a base 301 located below the transformer 2. The base 301 is fixedly connected to the inner bottom wall of the substation body 1. A first screw 302 is rotatably connected inside the base 301. A first motor 303 is fixedly connected to the rear side wall of the base 301. The drive end of the first motor 303 passes through the side wall of the base 301 and is fixedly connected to the rear end of the first screw 302. A first moving block 304 is threaded onto the first screw 302. An extension plate 305 is fixedly connected to the top of the first moving block 304. Two sliders 306 are symmetrically connected to the lower end of the extension plate 305. Guide rods 307 are slidably connected inside each slider 306. The two ends of the guide rods 307 are fixedly connected to the front and rear inner side walls of the base 301, respectively. A connecting shaft 308 is rotatably connected to the rear end of the extension plate 305. A follower gear 309 is fixedly connected to the bottom end of the connecting shaft 308. One side of the follower gear 309 has teeth. The rack 3010 is fixedly connected to the inner bottom wall of the base 301. The top end of the connecting shaft 308 is fixedly connected to the first bevel gear 3011. The upper end face of the extension plate 305 is fixedly connected to two mounting seats 3012. The two mounting seats 3012 are rotatably connected to the second screw 3013. The rear end of the second screw 3013 is fixedly connected to the second bevel gear 3014, which meshes with the first bevel gear 3011. The second screw 3013 is threadedly connected to the second moving block 3033. The upper end face of the extension plate 305 is symmetrically connected to two slide rails 3015. The two slide rails 3015 are slidably connected to the slide strips 3016. The top end of the second moving block 3033 and the slide strips 3016 is fixedly connected to the extension frame 3017. The extension frame 3017 is fixedly connected to the inner frame 3018. The transformer 2 is set between the inner frames 3018. The transformer 2 is fixedly connected to the extension frame 3017.

[0039] The first motor 303 is started, and the first motor 303 drives the first screw 302 to rotate within the base 301. Since the first moving block 304 is threadedly connected to the first screw 302, and the guide engagement between the slider 306 and the guide rod 307 restricts the rotation of the first moving block 304, the first moving block 304 drives the extension plate 305 to move axially along the guide rod 307. When the extension plate 305 moves, the follower gear 309 meshes with the rack 3010, driving the connecting shaft 308 and the first bevel gear 3011 to rotate. The first bevel gear 3011 drives the meshing second bevel gear 3014 and the second screw 3013 to rotate. When the second screw 3013 rotates, the second moving block 3033, under the guidance of the slide rail 3015 and the slide bar 3016, drives the extension frame 3017 to extend outward, ultimately realizing that the transformer 2 moves out of the substation body 1 synchronously with the extension frame 3017.

[0040] like Figures 1-7As shown, a rotating shaft 3019 is rotatably connected to the front ends of both side walls of the protruding frame 3017. A fixing sleeve 3020 is fixedly connected to the outer end of each rotating shaft 3019. A first telescopic cylinder 3021 is fixedly connected inside the fixing sleeve 3020. A first support seat 3022 is fixedly connected to the driving end of the first telescopic cylinder 3021. A third bevel gear 3023 is fixedly connected to the inner end of the rotating shaft 3019. Two support blocks 3024 are fixedly connected to the left and right inner side walls of the protruding frame 3017. A transmission rod 3025 is rotatably connected between two adjacent support blocks 3024. The front end of the transmission rod 3025 is fixedly connected to the third bevel gear 3023. The fourth bevel gear 3026 is meshed with the transmission rod 3025 and the fifth bevel gear 3027 is fixedly connected to the rear end. The connecting shaft 3028 is rotatably connected to the rear end of the extension frame 3017. Two sixth bevel gears 3029, which mesh with the fifth bevel gear 3027, are fixedly connected to the connecting shaft 3028. A worm gear 3030 is fixedly connected to the center of the connecting shaft 3028. A second motor 3031 is fixedly connected to the rear end side wall of the extension frame 3017. The drive end of the second motor 3031 passes through the rear end side wall of the extension frame 3017 and is fixedly connected to a worm 3032 that meshes with the worm gear 3030.

[0041] Start the second motor 3031, which drives the worm gear 3032 to rotate. The worm gear 3032 meshes with the worm wheel 3030, causing the connecting shaft 3028 to rotate. The sixth bevel gear 3029 on the connecting shaft 3028 drives the meshing fifth bevel gear 3027 and the transmission rod 3025 to rotate. The fourth bevel gear 3026 at the front end of the transmission rod 3025 drives the meshing third bevel gear 3023 and the rotating shaft 3019 to rotate, causing the fixed sleeve 3020 and the first telescopic cylinder 3021 to rotate to a vertically downward position. Control the drive end of the first telescopic cylinder 3021 to extend, causing the first support base 3022 to contact the ground and form a stable support, preventing the transformer 2 from shifting its center of gravity and tipping over after being moved. After the maintenance is completed, the transformer 2 can be reset by reversing the above procedure.

[0042] like Figure 1 and Figure 8 As shown, the heat dissipation component 4 includes a shield 401 fixed to the top of the substation body 1. The front end of the shield 401 has an installation port, and an assembly plate 402 is slidably connected inside the installation port. Fixing ears 403 are fixedly connected to both the left and right ends of the outer side wall of the assembly plate 402. The fixing ears 403 are fixedly connected to the shield 401 by bolts. Three cooling fans 404 are evenly fixedly connected to the assembly plate 402. A handle 405 is fixedly connected to the center of the outer side wall of the assembly plate 402.

[0043] The controller 6 controls the three cooling fans 404 to start. Outside air enters the interior of the shield 401 through the air inlet 407 at the rear end of the shield 401, and then enters the interior of the substation body 1 through the first round hole 406 and the second round hole 8. The cold air absorbs heat after flowing through the heat-generating components such as the transformer 2, forming hot air. The hot air is discharged through the heat dissipation holes 9 on the left and right side walls of the substation body 1, completing the air circulation and achieving heat dissipation and cooling. When it is necessary to inspect or clean the cooling fans 404, the bolts on the fixing ears 403 are unscrewed, and the mounting plate 402 is pulled out from the mounting port of the shield 401 through the handle 405. The operation is convenient.

[0044] like Figure 2 , Figure 8 and Figure 9 As shown, three first circular holes 406 corresponding to the positions of the cooling fan 404 are evenly opened on the inner bottom wall of the shield 401, and a set of air inlets 407 are evenly opened on the rear side wall of the shield 401; air is conveniently introduced through the air inlets 407.

[0045] like Figure 1 and Figure 2 As shown, the mobile component 5 includes a base frame 501 fixed to the lower end face of the substation body 1. Rollers 502 are rotatably connected to the base frame 501. A trailer seat 503 is fixedly connected to the center of the right end of the base frame 501. The left and right ends of the base frame 501 are symmetrical and fixedly connected to two fixing plates 504. A second telescopic cylinder 505 is fixedly connected to each fixing plate 504. The drive end of the second telescopic cylinder 505 passes through the fixing plate 504 and is fixedly connected to a second support seat 506.

[0046] The external traction equipment (such as a trailer) is connected to the trailer seat 503. The traction equipment drives the base frame 501 and the substation body 1 through the trailer seat 503. The entire unit moves by the rolling of the rollers 502, which can quickly transport it to the target power supply location. The drive end of the second telescopic cylinder 505 extends, driving the second support seat 506 to move downward until the second support seat 506 is in close contact with the ground and the rollers 502 are off the ground. The symmetrical support of the four second support seats 506 ensures the stability of the substation body 1 and prevents the equipment from slipping due to external forces or uneven ground during operation.

[0047] like Figure 2 As shown, a controller 6 and a temperature sensor 7 are fixedly connected to the inner top wall of the substation body 1. The controller 6 is electrically connected to the temperature sensor 7 and the cooling fan 404. When the temperature reaches the preset threshold of the controller 6, the controller 6 controls the three cooling fans 404 to start. When the temperature sensor 7 detects that the internal temperature is lower than the preset threshold, the controller 6 controls the cooling fans 404 to stop running, thereby realizing intelligent energy-saving heat dissipation.

[0048] like Figure 2and Figure 8 As shown, the upper surface of the substation body 1 has three second circular holes 8 corresponding to the positions of the cooling fan 404; the second circular holes 8 facilitate the entry of cold air into the substation body 1.

[0049] like Figure 1 and Figure 3 As shown, a set of heat dissipation holes 9 are evenly spaced on the left and right side walls of the substation body 1; the heat dissipation holes 9 facilitate the discharge of heat from the inside of the substation body 1.

[0050] like Figure 1 and Figure 9 As shown, the center of the front and rear side walls of the substation body 1 is connected to a first sealing door 10 by a hinge, and the left and right ends of the front side of the substation body 1 are connected to a second sealing door 11 by a hinge. The first sealing door 10 and the second sealing door 11 provide closed protection for the substation body 1. When closed in normal times, they can prevent external dust, rainwater, insects and other impurities from entering and protect the internal components from corrosion.

[0051] Specifically, when this mobile substation with rapid access is in use: when maintenance is required on transformer 2, the first motor 303 is started. The first motor 303 drives the first screw 302 to rotate within the base 301. Since the first moving block 304 is threadedly connected to the first screw 302, and the guide engagement between the slider 306 and the guide rod 307 restricts the rotation of the first moving block 304, the first moving block 304 drives the extension plate 305 to move axially along the guide rod 307. When the extension plate 305 moves, the follower gear 309 meshes with the rack 3010, driving the connecting shaft 308 and the first bevel gear 3011 to rotate. The first bevel gear 3011 drives the meshing second bevel gear 3014 and the second screw 3013 to rotate. When the second screw 3013 rotates, the second moving block 3033, guided by the slide rail 3015 and the slide bar 3016... The extension frame 3017 extends outward, ultimately allowing transformer 2 to move out of substation body 1 synchronously with the extension frame 3017. Then, the second motor 3031 is started, driving the worm gear 3032 to rotate. The worm gear 3032 meshes with the worm wheel 3030, driving the connecting shaft 3028 to rotate. The sixth bevel gear 3029 on the connecting shaft 3028 drives the meshing fifth bevel gear 3027 and transmission rod 3025 to rotate. The fourth bevel gear 3026 at the front end of the transmission rod 3025 drives the meshing third bevel gear 3023 and rotating shaft 3019 to rotate, causing the fixed sleeve 3020 and the first telescopic cylinder 3021 to rotate to a vertically downward state. The drive end of the first telescopic cylinder 3021 is controlled to extend, driving the first support base 3022 to contact the ground and form a stable support, facilitating maintenance of transformer 2 for subsequent rapid connection and use.

[0052] Temperature sensor 7 inside substation body 1 monitors the internal temperature in real time and transmits the monitoring data to controller 6. When the temperature reaches the preset threshold of controller 6, controller 6 controls three cooling fans 404 to start. Outside air enters the interior of shield 401 through air inlet 407 at the rear end of shield 401, and enters the interior of substation body 1 through first circular hole 406 and second circular hole 8. After the cold air flows through heat-generating components such as transformer 2 and absorbs heat, it becomes hot air. The hot air is discharged through heat dissipation holes 9 on the left and right side walls of substation body 1, completing air circulation and achieving heat dissipation and cooling. When temperature sensor 7 detects that the internal temperature is lower than the preset threshold, controller 6 controls the cooling fans 404 to stop running, realizing intelligent energy-saving heat dissipation.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
