Technical Field
[0001] This utility model relates to the field of prefabricated substation technology, specifically a fixed prefabricated substation with fire extinguishing function. Background Technology
[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor or outdoor power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines the functions of transformer voltage reduction and low-voltage power distribution, making it particularly suitable for urban power grid construction and renovation. It is a new type of substation that has emerged after civil engineering substations.
[0003] Traditional fixed prefabricated substations typically do not integrate fire suppression systems. If a fire breaks out inside a prefabricated substation, the high temperature and flames will severely damage the electrical components and cause the fire to spread. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixed box-type substation with fire extinguishing function to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A fixed prefabricated substation with fire extinguishing function includes a fixed prefabricated substation body, a fire extinguishing mechanism is provided on the surface of the fixed prefabricated substation body, an auxiliary fire extinguishing mechanism is provided on one side of the fixed prefabricated substation body, and a protective mechanism is provided on the top of the fixed prefabricated substation body.
[0007] The fire extinguishing mechanism includes a storage tank filled with carbon dioxide or heptafluoropropane. A solenoid valve is connected to the surface of the storage tank, and a flexible hose is connected to the surface of the solenoid valve. A first diversion pipe is connected to the surface of the flexible hose. A sliding groove is formed on the surface of the fixed transformer substation body. A sliding block is fixed to the surface of the first diversion pipe and is slidably connected to the surface of the sliding groove. A rodless cylinder is fixed to the inner wall of the fixed transformer substation body, and the moving part of the rodless cylinder is fixedly connected to the surface of the sliding block. Multiple first nozzles are connected to the surface of the first diversion pipe. A smoke detector is fixed to the inner wall of the fixed transformer substation body, and a controller is fixed to the surface of the fixed transformer substation body.
[0008] Preferably, a slide rail is fixed to the inner wall of the fixed transformer box body, a slide table is slidably connected to the surface of the slide rail, and the surface of the slide table is fixedly connected to the surface of the first shunt pipe.
[0009] Preferably, the auxiliary extinguishing mechanism includes a storage box filled with foam extinguishing agent. A delivery pump is connected to the surface of the storage box, and a delivery pipe is connected to the delivery end of the delivery pump. A second diversion pipe is connected to the surface of the delivery pipe. Multiple support blocks are fixed to the surface of the second diversion pipe. The bottom of the support blocks is fixedly connected to the top of the fixed transformer body. Multiple second nozzles are connected to the surface of the second diversion pipe. The second nozzles are rotated downwards at 45 degrees towards the ground.
[0010] Preferably, the protective mechanism includes two support plates, which are fixed to the top of the fixed transformer body. The two support plates are arranged back to back. A storage frame is fixed to the bottom of the support plate. Two extension blocks are fixed to the surface of the storage frame. A baffle is hinged to the surface of the extension block.

[0012] Preferably, telescopic covers are fixed on both sides of the surface of the sliding block, and one end of the telescopic cover is fixedly connected to one side of the inner wall of the sliding groove.
[0013] Preferably, a buzzer is fixed to the top of the support plate, and two feeding doors are hinged to the surface of the support plate.
[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0015] First, this utility model significantly improves the fire response capability of the fixed transformer substation through the fire extinguishing mechanism and the auxiliary fire extinguishing mechanism. The fire extinguishing mechanism uses a clean gas extinguishing agent, which can quickly reduce the temperature inside the box and avoid the risk of corrosion to precision electrical components by traditional dry powder extinguishing agents. The dynamic spray mode drives the nozzle to move through a rodless cylinder, which has a larger coverage area than traditional fixed nozzles. The foam extinguishing agent of the auxiliary fire extinguishing mechanism is designed for ground flowing fires. Its 45-degree inclined nozzle can form a continuous foam layer, effectively preventing the fire from spreading to the surrounding area.
[0016] Secondly, in this utility model, the fireproof sand barrier of the protective mechanism provides physical isolation in extreme situations. When the cylinder is pushed, it drives the baffle to rotate around the hinge point of the extension block, causing the baffle to rotate downward and open, thereby releasing the fireproof sand in the storage frame and allowing the fireproof sand to fall onto the ground on both sides of the fixed transformer body. The fireproof sand laid on the ground, together with the foam extinguishing agent, further delays the spread of fire and improves the safety of the equipment. Attached Figure Description

[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.
[0024] Please see Figure 1-5 A fixed box-type substation with fire extinguishing function includes a fixed box-type substation body 1, a fire extinguishing mechanism 2 is provided on the surface of the fixed box-type substation body 1, an auxiliary fire extinguishing mechanism 3 is provided on one side of the fixed box-type substation body 1, and a protective mechanism 4 is provided on the top of the fixed box-type substation body 1.
[0025] The fire extinguishing mechanism 2 includes a storage tank 201, which is filled with carbon dioxide or heptafluoropropane. A solenoid valve 202 is connected to the surface of the storage tank 201. A hose 203 is connected to the surface of the solenoid valve 202. A first diversion pipe 204 is connected to the surface of the hose 203. A sliding groove is opened on the surface of the fixed transformer substation body 1. A sliding block 205 is fixed on the surface of the first diversion pipe 204. The sliding block 205 is slidably connected to the surface of the sliding groove. A rodless cylinder 207 is fixed on the inner wall of the fixed transformer substation body 1. The moving part of the rodless cylinder 207 is fixedly connected to the surface of the sliding block 205. Multiple first nozzles 206 are connected to the surface of the first diversion pipe 204. A smoke detector 208 is fixed on the inner wall of the fixed transformer substation body 1. A controller 6 is fixed on the surface of the fixed transformer substation body 1.
[0026] Through the above technical solution, the carbon dioxide or heptafluoropropane filled in the storage tank 201 is released under the control of the solenoid valve 202. After the smoke alarm 208 detects the fire, the controller 6 simultaneously opens the solenoid valve 202 and the rodless cylinder 207 to achieve dynamic spraying. The rodless cylinder 207 drives the sliding block 205 to move the first diversion pipe 204 back and forth, expanding the coverage of the extinguishing agent sprayed by the first nozzle 206 and reducing dead zones. Moreover, carbon dioxide or heptafluoropropane, as a clean extinguishing agent, can avoid secondary damage to the internal equipment of the fixed transformer substation body 1 and adapt to the complex internal environment of the transformer substation.
[0027] The inner wall of the fixed transformer body 1 is fixed with a slide rail 209, and a slide table 210 is slidably connected to the surface of the slide rail 209. The surface of the slide table 210 is fixedly connected to the surface of the first shunt pipe 204.
[0028] Through the above technical solution, the cooperation between the slide rail 209 and the slide table 210 reduces the motion resistance, improves the movement accuracy of the first diversion tube 204, and provides support for one side of the first diversion tube 204, reducing the occurrence of offset.
[0029] The auxiliary extinguishing mechanism 3 includes a storage box 301, which is filled with foam extinguishing agent. A delivery pump 302 is connected to the surface of the storage box 301. A delivery pipe 303 is connected to the delivery end of the delivery pump 302. A second diversion pipe 305 is connected to the surface of the delivery pipe 303. Multiple support blocks 304 are fixed to the surface of the second diversion pipe 305. The bottom of the support blocks 304 is fixedly connected to the top of the fixed transformer body 1. Multiple second nozzles 306 are connected to the surface of the second diversion pipe 305. The second nozzles 306 are rotated downward at 45 degrees towards the ground.
[0030] Through the above technical solution, the foam extinguishing agent in the storage tank 301 is pressurized by the delivery pump 302, enters the second diversion pipe 305 through the delivery pipe 303, and is then sprayed downwards to the ground by the second nozzle 306 at a 45-degree angle, forming a foam covering layer. The foam extinguishing agent effectively isolates oxygen, improves the fire prevention effect, reduces the speed of fire spread, and provides valuable time for rescue.
[0031] The protective mechanism 4 includes two support plates 401, which are fixed to the top of the fixed transformer body 1. The two support plates 401 are arranged back to back. A storage frame 402 is fixed to the bottom of the support plate 401. Two extension blocks 403 are fixed to the surface of the storage frame 402. A baffle 404 is hinged to the surface of the extension blocks 403. Two push cylinders 405 are hinged to the bottom of the support plate 401. The surface of the push cylinder 405 is hinged to the top of the baffle 404. The storage frame 402 is filled with fireproof sand.
[0032] Through the above technical solution, when the cylinder 405 is pushed, the cylinder 405 drives the baffle 404 to rotate around the hinge point of the extension block 403, so that the baffle 404 rotates downward and opens, thereby releasing the fireproof sand in the storage frame 402. The fireproof sand falls down along the inclined surface of the baffle 404 onto the ground on the front and rear sides of the fixed transformer body 1. The fireproof sand laid on the ground, together with the foam extinguishing agent, further delays the spread of fire and improves the safety of the equipment.
[0033] A rubber pad 406 is fixed to the bottom of the storage box 402.
[0034] With the above technical solution, under normal circumstances, the top of the baffle 404 contacts the surface of the rubber pad 406, allowing the rubber pad 406 to be deformed under pressure, thereby improving the sealing effect and preventing the leakage of fire sand.
[0035] Telescopic covers 211 are fixed on both sides of the surface of the sliding block 205, and one end of the telescopic cover 211 is fixedly connected to one side of the inner wall of the slide groove.
[0036] Through the above technical solution, the telescopic cover 211 can extend and retract when the sliding block 205 moves, thereby forming a shielding effect on the surface of the slide groove, making it difficult for dust to enter the interior of the fixed transformer body 1 through the slide groove.
[0037] A buzzer 5 is fixed to the top of the support plate 401, and two feeding doors 407 are hinged to the surface of the support plate 401.
[0038] Through the above technical solution, when the smoke alarm 208 detects a fire, the smoke alarm 208 transmits a signal to the controller 6, and the controller 6 can activate the buzzer 5 so that the buzzer 5 can emit a warning sound to remind people in the vicinity that there is a fire. The design of the feeding door 407 facilitates the rapid replenishment of fireproof sand after a disaster.
[0039] The controller 6 is electrically connected to the actuating cylinder 405, the buzzer 5, the smoke alarm 208, the rodless cylinder 207, the delivery pump 302, and the solenoid valve 202.
[0040] In operation, when a fire breaks out in the fixed transformer substation 1 due to an electrical fault or short circuit, the smoke alarm 208 detects the smoke particles first and immediately sends a signal to the controller 6. The controller 6 then simultaneously activates the emergency procedures of the fire extinguishing mechanism 2 and the auxiliary fire extinguishing mechanism 3. During the response phase of the fire extinguishing mechanism 2, the solenoid valve 202 opens, and the high-pressure carbon dioxide or heptafluoropropane in the storage tank 201 enters the first diversion pipe 204 through the hose 203. At the same time, the rodless cylinder 207 drives the sliding block 205 to reciprocate along the slide groove, causing the first nozzle 206 to dynamically sweep the interior of the transformer substation. To effectively extinguish the fire inside the fixed transformer substation body 1, during the auxiliary extinguishing mechanism 3 coordination phase, the controller 6 starts the delivery pump 302 to deliver the foam extinguishing agent in the storage box 301 to the second nozzle 306 through the second diversion pipe 305. The nozzle covers the ground around the fixed transformer substation body 1 at a downward tilt angle of 45 degrees, forming a foam isolation zone to block the fire from spreading outward. At the same time, the cylinder 405 is pushed to push and open the baffle 404, and the fireproof sand in the storage box 402 slides down the inclined baffle 404 to the ground, forming a fire-resistant barrier in front and behind, delaying the spread of the fire.
