Description

Technical Field

[0001] This invention belongs to the field of electrical cabinet technology, and particularly relates to an electrical cabinet. Background Technology

[0002] Streetlights are often installed in the middle of auxiliary roads and sidewalks, along with electrical cabinets of varying heights for shops along the street. The special location of these electrical cabinets makes them vulnerable to collisions with vehicles. After a collision, the components and wiring inside the electrical cabinets can be damaged, causing widespread power outages or even fires.

[0003] Currently, there are many electrical cabinets designed for impact resistance, which use measures to increase the strength of the cabinet, but the protection capability is still relatively weak and the effect is poor. In the event of an accidental large impact, the cabinet will still deform, and the deformed cabinet will still squeeze the components and cause short circuits.

[0004] Currently, the cabinet will directly cut off the power in the event of a fire, which is rather crude in terms of fire prevention and lacks attention to detail. For example, if a small fire is caused by a minor impact, the cabinet can be sealed, and the time it takes for the oxygen inside the cabinet to burn out will not be long, allowing some components to continue to function normally.

[0005] In addition, the current equipment loses power inside the cabinet when a fire occurs, which is not very safe; the wires inserted into the cabinet remain energized.

[0006] This invention designs an electrical cabinet to solve the above problems. Summary of the Invention

[0007] To achieve the above objectives, the present invention employs the following technical solutions: An electrical cabinet includes a cabinet body, a cabinet door, a fixing rod, an adjusting plate, a connecting assembly, a third spring, a triggering assembly, a sealing adjusting assembly one, and a sealing adjusting assembly two. A fixing lug is fixedly installed at one of the pointed corners of the cabinet body, and the fixing rod is fixedly installed on the road surface. The cabinet body is sway-mounted on the fixing rod via the fixing lug. The cabinet body has evenly distributed ventilation holes on the side facing away from the road surface and in the direction of vehicle travel. A sealing adjusting assembly one, capable of sealing the ventilation holes, is installed inside the cabinet body near the side with the ventilation holes. The cabinet door is located on the side facing away from the road surface and also has evenly distributed ventilation holes. A sealing adjusting assembly two, capable of sealing the ventilation holes on the cabinet door, is installed between the cabinet door and the cabinet body.

[0008] An installation slider is slidably mounted on the bottom plate inside the cabinet, and a third spring is installed between the installation slider and the bottom plate. An adjustment plate is mounted on the installation slider. The adjustment plate is composed of multiple unit plates, which are hinged to each other and have leaf springs installed between them. Electrical components are mounted on the adjustment plate. Two unit plates on both sides are connected to the rear plate inside the cabinet by elastic ropes. A limit block is slidably mounted on the bottom plate of the cabinet, and a fourth spring is installed between the limit block and the bottom plate. The limit block limits the installation slider, and the limit block is connected to a fixing rod by a second pull rope.

[0009] One end of the internal wire is connected to the electrical components installed inside the cabinet, and the other end of the internal wire passes through the cabinet, through the fixing rod, and is connected to the external wire through the connecting assembly.

[0010] The connection assembly includes a male plug and a female plug, wherein the female plug is connected to an external wire and has a socket; the male plug is fixed to one end of an internal wire, and a sliding plate is slidably installed inside the male plug, with a second spring installed between the sliding plate and the male plug; the core of the internal wire passes through the male plug and is fixed on the sliding plate, and a conductive connecting plate is installed at its end; the plug is installed on the male plug, with one end of the plug extending out of the male plug, and a conductive connecting plate installed at the other end of the plug, which mates with the connecting plate on the core of the internal wire.

[0011] Two triggering components are installed inside the cabinet. When the temperature inside the cabinet is too high, the triggering components can control the sliding plate to separate the internal wires and the connecting plate on the plug.

[0012] As a preferred embodiment, the sealing adjustment assembly includes a sealing plate, a connecting plate, a first connecting rod, a first swing rod, a mounting lug, a telescopic guide rod, a first spring, a limiting block, a limiting plate, a fixed support, and a paraffin wax assembly. Two guide strips are symmetrically installed on the cabinet panel with ventilation holes.

A limiting plate is fixedly installed on the side of the connecting plate facing away from the sealing plate, and a first spring is installed between the limiting plate and the cabinet bottom plate. The mounting lug is fixedly installed on the cabinet bottom plate, and the lower end of the first swing rod is swung and installed on the mounting lug. A limiting block is fixedly installed on one side of the first swing rod, cooperating with the limiting plate and located below the limiting plate. The upper end of the first swing rod is hinged to the first connecting rod, and the paraffin wax assembly is installed inside the cabinet via a fixed support. The output end of the paraffin wax assembly is connected to the first connecting rod via a hinge.

[0013] The second sealing adjustment assembly includes a sealing plate, a connecting plate, a first connecting rod, a first swing rod, a mounting lug, a telescopic guide rod, a first spring, a limiting block, a limiting plate, a fixed support, and a paraffin wax assembly. Two guide strips are symmetrically installed on the cabinet door. Multiple sealing plates are fixedly connected by a connecting plate, and the sealing plates are slidably installed within their corresponding two guide strips, each corresponding to a ventilation hole. A limiting plate is fixedly installed on the side of the connecting plate facing away from the sealing plate, and a first spring is installed between the limiting plate and the cabinet door. The mounting lug is fixedly installed on the cabinet bottom plate. The lower end of the first swing rod is swung and installed on the mounting lug. A limiting block is fixedly installed on one side of the first swing rod, cooperating with the limiting plate and located below it. The upper end of the first swing rod is hinged to the first connecting rod. The first paraffin wax assembly is installed inside the cabinet via a fixed support, and its output end is hinged to the first connecting rod.

[0014] As a preferred embodiment, a clearance notch is provided at the location where the internal wire passes through the fixing rod.

[0015] As a preferred embodiment, the triggering assembly includes a second swing arm, a second paraffin component, a rope loop, a steel wire rope, and a second connecting rod. The upper end of the second swing arm is oscillatingly mounted on the top plate of the cabinet. The second paraffin component is mounted inside the cabinet. The output end of the second paraffin component is connected to the second swing arm via the second connecting rod. Both ends of the second connecting rod are hinged to the second paraffin component and the second swing arm. A first pull rope is installed on one side of the second swing arm. The first pull rope consists of an outer rope loop and an inner steel wire rope. The two ends of the rope loop are fixedly mounted on the cabinet and the male plug, respectively. One end of the steel wire rope is fixedly connected to the second swing arm, and the other end of the steel wire rope is connected to the sliding plate in the connecting assembly.

[0016] As a preferred embodiment, a heat insulation cover is installed on the outer side of the paraffin component two.

[0017] As a preferred embodiment, the bottom of the cabinet is equipped with casters.

[0018] As a preferred embodiment, a needle is installed on one side of the second lever in one of the two triggering components; the fire ball is installed inside the cabinet and cooperates with the needle on the second lever; the ball of the fire ball is made of a fragile material.

[0019] As a preferred embodiment, a tightening bolt is installed between the male plug and the female plug.

[0020] As a preferred embodiment, the other side of the cabinet is fixedly connected to the ground by bolts.

[0021] As a preferred embodiment, the male plug is equipped with a limiting protrusion that limits the sliding plate; a locking block is slidably installed inside the male plug, and one side of the locking block has an inclined surface; a fifth spring is installed between the locking block and the male plug; a pull ring is installed on the locking block; and the inclined surface on the locking block cooperates with the sliding plate.

[0022] Compared with existing technologies, the advantages of this invention are: 1. In this invention, the electrical cabinet is located on one side of the road. When a car is driving, it may hit the back of the electrical cabinet and the side facing the direction of the car's travel, or directly hit the support rod. After being hit, the side or back of the electrical cabinet will rotate around the fixed rod. The rotation will buffer part of the impact force, reduce the damage to the electrical cabinet after being hit, and protect the electrical cabinet. When the car hits the fixed rod, the fixed rod will act as a barrier to the car and will protect the electrical cabinet.

[0023] 2. Under normal conditions, the adjusting plate remains flat due to the action of the third spring, elastic rope, leaf spring, and limit block. In actual use, when the side or back panel of the electrical cabinet is impacted, the cabinet panel deforms, and the cabinet rotates around the fixed rod. Because one end of the second pull rope is fixed to the fixed rod, it is pulled relative to the cabinet during rotation. This sliding of the second pull rope causes the limit block to slide, releasing it from its position on the mounting slider. Once the limit block releases its position on the mounting slider, the adjusting plate deforms under the combined action of the third spring, elastic rope, leaf spring, and hinge structure, forming an arc-like shape. This keeps both ends of the adjusting plate away from the side panel of the electrical cabinet, preventing the deformed side panel from pressing on the electrical components on the adjusting plate and causing damage.

[0024] 3. This invention incorporates ventilation openings on the side panels and cabinet doors that are not subject to impact. In the event of a fire inside the electrical cabinet, the paraffin component deforms and elongates upon heating. This elongation causes the first connecting rod to swing, which in turn causes the first swing arm to swing. This releases the limiting block mounted on the first swing arm from its restraint on the limiting plate. After the limiting block releases its restraint on the limiting plate, the connecting plate moves downward under the action of the first spring. This downward movement of the connecting plate causes the sealing plate fixed to it to move downward, sealing the corresponding ventilation opening. This isolates the air inside the electrical cabinet. Once the oxygen inside the electrical cabinet is consumed, the fire will automatically extinguish. This type of fire extinguishing is suitable for small fires.

[0025] 4. If the fire inside the electrical cabinet cannot be completely extinguished after the ventilation opening is closed, the temperature inside the electrical cabinet will continue to rise. When the temperature inside the electrical cabinet is high enough to cause the paraffin component two installed inside the heat insulation cover to deform and elongate, the elongation of the paraffin component two will cause the second connecting rod to swing. The second connecting rod will cause the second swing arm to swing. The swing arm will pull the steel wire rope to slide in the rope sleeve. The sliding of the steel wire rope will pull the sliding plate to slide. The sliding of the sliding plate will cause the core of the internal wire to slide, causing the core of the internal wire to separate from the plug, that is, the internal wire and the external wire are disconnected, and the power supply to the electrical cabinet is disconnected.

[0026] 5. In this invention, when subjected to an impact, the electrical cabinet will swing around the fixed rod, and the adjustment plate inside the cabinet where electrical components are installed will deform. The deformation of the adjustment plate is triggered by the swing of the electrical cabinet relative to the fixed rod, and the electrical cabinet protection components have a high degree of integration.

[0049] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following embodiments and drawings are used to illustrate the present invention, but are not intended to limit the scope of the invention.

[0050] An electrical cabinet 2, such as Figure 1 , 2 As shown in Figure 3, it includes a cabinet body 3, a cabinet door 4, a fixing rod 5, an adjusting plate 47, a connecting assembly 25, a third spring 46, a trigger assembly 28, a sealing adjusting assembly one 7, and a sealing adjusting assembly two 21. A fixing lug 9 is fixedly installed at one of the pointed corners of the cabinet body 3, and the fixing rod 5 is fixedly installed on the ground surface 1. Figure 4 As shown, cabinet 3 is sway-mounted on fixed rod 5 via fixed lugs 9; casters 26 are installed at the bottom of cabinet 3; the other side of cabinet 3 is fixedly connected to the ground by bolts; evenly distributed heat dissipation holes are opened on the cabinet panel on the side of cabinet 3 facing away from the direction of vehicle travel on road 1, such as... Figure 5 , 6 As shown, a sealing adjustment component 7, capable of sealing the ventilation holes, is installed inside cabinet 3 near the cabinet panel with ventilation holes. Figure 8 , 9 As shown, the cabinet door 4 is located on the side facing away from the road surface 1 and has evenly distributed heat dissipation holes. A sealing adjustment component 21 that can seal the heat dissipation holes on the cabinet door 4 is installed between the cabinet door 4 and the cabinet body 3.

[0051] In this invention, electrical cabinet 2 is located on one side of the road, such as... Figure 21 As shown in Figure a, during vehicle operation, the vehicle may impact the back of electrical cabinet 2, the side facing the vehicle's direction of travel, or directly impact the support rod. Figure 21 As shown in b in 21 and c in 21, the side or back of the electrical cabinet 2 will rotate around the fixed rod 5 after being impacted. The rotation will buffer part of the impact force, reduce the damage to the electrical cabinet 2 after being impacted, and protect the electrical cabinet 2. When the car hits the fixed rod 5, the fixed rod 5 will block the car and protect the electrical cabinet 2.

[0052] The present invention provides a rotating wheel 26 at the bottom of the electrical cabinet 2, and the axis of rotation of the rotating wheel 26 is tangent to the rotation trajectory of the electrical cabinet 2. The rotating wheel 26 makes the friction between the electrical cabinet 2 and the ground become rolling friction. Compared with the traditional direct contact between the electrical cabinet 2 and the ground, rolling friction can reduce the wear and tear caused by friction at the bottom of the electrical cabinet 2.

[0053] In this invention, the ring of the fixed lug 9 is embedded in the fixed rod 5. When the car directly hits the fixed rod 5, the fixed rod 5 bears the impact force; the fixed lug 9 will not be damaged.

[0054] In this invention, the side of the cabinet 3 away from the fixing rod 5 is fixed to the ground by bolts. During normal use, the electrical cabinet 2 is fixed to the ground by bolts and cannot rotate around the fixing rod 5. In this state, the electrical cabinet 2 is equivalent to a normal electrical cabinet 2.

[0055] like Figure 7 As shown, the sealing adjustment assembly 7 includes a sealing plate 10, a connecting plate 11, a first connecting rod 12, a first swing rod 13, a mounting lug 14, a telescopic guide rod 15, a first spring 16, a limiting block 17, a limiting plate 18, a fixed support 19, and a paraffin wax assembly 20. Two guide strips 22 are symmetrically installed on the cabinet panel with ventilation holes. Multiple sealing plates 10 are fixedly connected by a connecting plate 11. The sealing plates 10 are slidably installed within the corresponding two guide strips 22 and correspond one-to-one with the ventilation holes. The connecting plate 11 is fixed on the side facing away from the sealing plate 10. A limiting plate 18 is installed, and a first spring 16 is installed between the limiting plate 18 and the bottom plate of the cabinet 3. A mounting lug 14 is fixedly installed on the bottom plate of the cabinet 3. The lower end of the first swing rod 13 is swung and installed on the mounting lug 14. A limiting block 17 is fixedly installed on one side of the first swing rod 13. The limiting block 17 cooperates with the limiting plate 18 and is located on the lower side of the limiting plate 18. A first connecting rod 12 is hinged to the upper end of the first swing rod 13. The paraffin component 20 is installed in the cabinet 3 through a fixed support 19. The output end of the paraffin component is connected to the first connecting rod 12 by a hinge.

[0056] like Figure 9 As shown, the sealing adjustment assembly 21 includes a sealing plate 10, a connecting plate 11, a first connecting rod 12, a first swing rod 13, a mounting lug 14, a telescopic guide rod 15, a first spring 16, a limiting block 17, a limiting plate 18, a fixed support 19, and a paraffin wax assembly 20. Two guide strips 22 are symmetrically installed on the cabinet door 4. Multiple sealing plates 10 are fixedly connected by a connecting plate 11. The sealing plates 10 are slidably installed within the corresponding two guide strips 22 and correspond one-to-one with the ventilation holes. The connecting plate 11 is fixedly installed on the side facing away from the sealing plate 10. A limiting plate 18 is installed, and a first spring 16 is installed between the limiting plate 18 and the cabinet door 4; a mounting lug 14 is fixedly installed on the bottom plate of the cabinet body 3, and the lower end of the first swing rod 13 is swung and installed on the mounting lug 14. A limiting block 17 is fixedly installed on one side of the first swing rod 13, and the limiting block 17 cooperates with the limiting plate 18 and is located on the lower side of the limiting plate 18; a first connecting rod 12 is hinged to the upper end of the first swing rod 13, and a paraffin component 20 is installed in the cabinet body 3 through a fixed support 19. The output end of the paraffin component is connected to the first connecting rod 12 by a hinge.

[0057] Under normal conditions, the limiting block 17 is located below the limiting plate 18 and limits the downward movement of the limiting plate 18. The invention includes ventilation openings on the side panels and cabinet door 4, which are not subject to impact. In the event of a fire inside the electrical cabinet 2, the paraffin component 20 deforms and elongates when heated. This elongation causes the first connecting rod 12 to swing, which in turn causes the first swing rod 13 to swing, releasing the limiting block 17 from limiting the limiting plate 18. After the limiting block 17 releases its restriction, the connecting plate 11 moves downward under the action of the first spring 16. This downward movement of the connecting plate 11 causes the sealing plate 10, which is fixedly installed on it, to move downward, sealing the corresponding ventilation opening. This isolates the air inside the electrical cabinet 2, and the fire will automatically extinguish once the oxygen inside the electrical cabinet 2 is consumed. This type of fire extinguishing is suitable for small fires.

[0058] like Figure 12 As shown, a mounting slider 48 is slidably mounted on the bottom plate inside the cabinet 3, and a third spring 46 is installed between the mounting slider 48 and the bottom plate; an adjusting plate 47 is mounted on the mounting slider 48, such as... Figure 18 , 19 As shown in Figure 20, the adjustment plate 47 is composed of multiple unit plates, which are hinged to each other and a leaf spring 51 is installed between adjacent unit plates; electrical components 50 are installed on the adjustment plate 47, and the two unit plates on both sides are connected to the inner rear plate of the cabinet 3 by elastic ropes 49; a limit block 53 is slidably installed on the bottom plate of the cabinet 3, and a fourth spring 54 is installed between the limit block 53 and the bottom plate of the cabinet 3; the limit block 53 limits the installation slider 48, and the limit block 53 is connected to the fixing rod 5 by a second pull rope 52.

[0059] Under normal conditions, the adjusting plate 47 is in a flat state under the action of the third spring 46, elastic rope 49, leaf spring 51, and limiting block 53. In actual use, when the side or back panel of the electrical cabinet 2 is impacted, the impacted cabinet panel will deform, and the electrical cabinet 2 will rotate around the fixed rod 5. Because one end of the second pull rope 52 is fixedly installed on the fixed rod 5, the second pull rope 52 will be pulled and slide relative to the cabinet body 3 during rotation. The sliding of the second pull rope 52 causes the limiting block 53 to slide, thus releasing the limiting block 53 from restricting the mounting slider 48. When the limiting block 53 releases the limiting block 53 from restricting the mounting slider 48, as... Figure 22 As shown, under the combined action of the third spring 46, elastic rope 49, leaf spring 51 and hinge structure, the adjusting plate 47 will deform to form an arc-like shape; this will cause the two ends of the adjusting plate 47 to move away from the side plate of the electrical cabinet 2, preventing the deformed side plate from squeezing the electrical components 50 on the adjusting plate 47 and causing damage to the electrical components 50.

[0060] like Figure 10 ,11 As shown, one end of the internal wire 24 is connected to the electrical component 50 installed inside the cabinet 3, and the other end of the internal wire 24 passes through the cabinet 3, exits from the fixing rod 5, and is connected to the external wire 6 through the connecting assembly 25; as shown Figure 13 As shown, there is an avoidance notch 37 at the position where the internal wire 24 passes through the fixing rod 5.

[0061] like Figure 14 , 15 As shown, the connection assembly 25 includes a male plug 35 and a female plug 36, wherein the female plug 36 is connected to the external power cord 6, as shown. Figure 16 As shown, the female plug 36 has a socket 42; Figure 17 As shown, the male plug 35 is fixed to one end of the internal wire 24, and a sliding plate 44 is slidably installed inside the male plug 35. A second spring 40 is installed between the sliding plate 44 and the male plug 35. The wire core 39 of the internal wire 24 passes through the male plug 35 and is fixed on the sliding plate 44, and a conductive connecting plate 45 is installed at its end. The plug 41 is installed on the male plug 35, with one end of the plug 41 extending out of the male plug 35 and the other end of the plug 41 being equipped with a conductive connecting plate 45, which mates with the connecting plate 45 on the wire core 39 of the internal wire 24. A tightening bolt 38 is installed between the male plug 35 and the female plug 36.

[0062] like Figure 17 As shown, a limiting protrusion 43 is installed inside the male plug 35 to limit the sliding plate 44; as Figure 14 As shown, a locking block 55 is slidably installed inside the male plug 35, and one side of the locking block 55 has an inclined surface; a fifth spring 56 is installed between the locking block 55 and the male plug 35; a pull ring 57 is installed on the locking block 55; the inclined surface on the locking block 55 cooperates with the sliding plate 44.

[0063] like Figure 12 As shown, two trigger components 28 are installed inside the cabinet 3. When the temperature inside the cabinet 3 is too high, the trigger components 28 can control the slide plate 44 to slide, causing the internal wire 24 and the connecting plate 45 on the plug 41 to separate.

[0064] like Figure 12As shown, the triggering component 28 includes a second swing rod 29, a second paraffin component 30, a rope loop 32, a steel wire rope 33, and a second connecting rod 34. The upper end of the second swing rod 29 is oscillatingly mounted on the top plate of the cabinet 3. The second paraffin component 30 is installed inside the cabinet 3, and a heat insulation cover 31 is installed on the outside of the second paraffin component 30. The output end of the second paraffin component 30 is connected to the second swing rod 29 through the second connecting rod 34. The two ends of the second connecting rod 34 are connected to the second paraffin component 30 and the second swing rod 29 by hinge. A first pull rope 23 is installed on one side of the second swing rod 29. The first pull rope 23 consists of an outer rope loop 32 and an inner steel wire rope 33. The two ends of the rope loop 32 are fixedly mounted on the cabinet 3 and the male plug 35, respectively. One end of the steel wire rope 33 is fixedly connected to the second swing rod 29, and the other end of the steel wire rope 33 is connected to the slide plate 44 in the connecting component 25. In this invention, the heat insulation cover 31 can provide heat insulation for the paraffin component 2 30 when a fire occurs and the fire temperature is low, preventing the paraffin component 2 30 from being triggered at this temperature and causing the input power to be cut off. In this state, since the fire is relatively small, only the paraffin component 1 20 can be triggered to close the ventilation opening of the electrical cabinet for fire extinguishing. Only when the fire inside the electrical cabinet 2 is large and cannot be completely extinguished after closing the ventilation opening, and the temperature inside the electrical cabinet 2 continues to rise, will the paraffin component 2 30 be triggered to cut off the power.

[0065] If the fire inside the electrical cabinet 2 cannot be completely extinguished after the ventilation is closed, the temperature inside the electrical cabinet 2 will continue to rise. When the temperature inside the electrical cabinet 2 is high enough to cause the paraffin component 2 30 installed in the heat insulation cover 31 to deform and elongate, the elongation of the paraffin component 2 30 will cause the second connecting rod 34 to swing. The second connecting rod 34 will cause the second swing rod 29 to swing. The swing rod 29 will pull the steel wire rope 33 to slide in the rope sleeve 32. The sliding of the steel wire rope 33 will pull the sliding plate 44 to slide. The sliding of the sliding plate 44 will cause the core 39 of the internal wire 24 to slide, causing the core 39 of the internal wire 24 to separate from the plug 41, that is, the internal wire 24 and the external wire 6 will be disconnected, and the power supply to the electrical cabinet 2 will be disconnected.

[0066] When the slide plate 44 slides, it presses against the locking block 55. Under the action of the inclined surface on the locking block 55, the locking block 55 moves upward relative to the male plug 35. After the slide plate 44 passes the locking block 55, the locking block 55 resets under the action of the fifth spring 56, which limits the reset of the slide plate 44. Because the internal electronic components will be damaged after a fire, the electrical cabinet 2 cannot be powered. Therefore, the locking block 55 limits the sliding plate 44, so that the connecting assembly 25 is always in the disconnected state. In this invention, the pull ring 57 can pull up the locking block 55 when resetting the slide plate 44, so that the slide plate 44 resets under the action of the second spring 40.

[0067] The first pull rope 23 of the present invention is divided into two parts: a rope sleeve 32 and a steel wire rope 33. The rope sleeve 32 is fixed and stationary, while the steel wire rope 33 can slide relative to the rope sleeve 32. The first pull rope 23 is the prior art.

[0068] like Figure 12 As shown, a needle is installed on one side of the second swing arm 29 in one of the two triggering components 28; a fire-fighting ball 27 is installed inside the cabinet 3 and cooperates with the needle on the second swing arm 29; the ball of the fire-fighting ball 27 is made of a fragile material. When the second swing arm 29 swings, it will cause the needle to swing and puncture the fire-fighting ball 27. After the fire-fighting ball 27 explodes, it will play a role in extinguishing the fire inside the electrical cabinet 2.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0070] Implementation: When using the electrical cabinet 2 designed according to the present invention, if a car hits the side panel or back panel of the electrical cabinet 2, such as... Figure 21 As shown in b and c of 21, when the side or back of the electrical cabinet 2 is impacted, it will rotate around the fixed rod 5. The rotation will buffer part of the impact force, reduce the damage to the electrical cabinet 2 after the impact, and protect the electrical cabinet 2. At the same time, the cabinet panel of the electrical cabinet 2 will deform after the impact, and the electrical cabinet 2 will rotate around the fixed rod 5. Since one end of the second pull rope 52 is fixedly installed on the fixed rod 5, the second pull rope 52 will be pulled and slide relative to the cabinet body 3 during the rotation. The sliding of the second pull rope 52 will drive the limit block 53 to slide, so that the limit block 53 releases the limit on the mounting slider 48. When the limit block 53 releases the limit on the mounting slider 48, the adjusting plate 47 will deform under the combined action of the third spring 46, elastic rope 49, leaf spring 51 and hinge structure, forming an arc-like shape. This will make the two ends of the adjusting plate 47 move away from the side panel of the electrical cabinet 2, preventing the deformed side panel from squeezing the electrical components 50 on the adjusting plate 47 and causing damage to the electrical components 50.

[0071] When a car hits the fixed bar 5, the fixed bar 5 acts as a stop for the car and protects the electrical cabinet 2.

[0072] When a fire occurs inside electrical cabinet 2, the paraffin component 20 deforms and elongates when heated. This elongation causes the first connecting rod 12 to swing, which in turn causes the first swing rod 13 to swing. This releases the limiting block 17 mounted on the first swing rod 13 from its limiting plate 18. After the limiting block 17 releases its limiting plate 18, the connecting plate 11 moves downward under the action of the first spring 16. This downward movement of the connecting plate 11 causes the sealing plate 10, which is fixedly mounted on it, to move downward, sealing the corresponding ventilation opening. This isolates the air inside electrical cabinet 2. Once the oxygen inside electrical cabinet 2 is consumed, the fire will automatically extinguish. This type of fire extinguishing is suitable for small fires.

[0073] If the fire inside the electrical cabinet 2 cannot be completely extinguished after the ventilation is closed, the temperature inside the electrical cabinet 2 will continue to rise. When the temperature inside the electrical cabinet 2 is high enough to cause the paraffin component 2 30 installed in the heat insulation cover 31 to deform and elongate, the elongation of the paraffin component 2 30 will cause the second connecting rod 34 to swing. The second connecting rod 34 will cause the second swing rod 29 to swing. The swing rod 29 will pull the steel wire rope 33 to slide in the rope sleeve 32. The sliding of the steel wire rope 33 will pull the sliding plate 44 to slide. The sliding of the sliding plate 44 will cause the core 39 of the internal wire 24 to slide, causing the core 39 of the internal wire 24 to separate from the plug 41, that is, the internal wire 24 and the external wire 6 will be disconnected, and the power supply to the electrical cabinet 2 will be disconnected.
