Description

Technical Field

[0001] The invention belongs to the technical field of fire alarm lighting equipment, and in particular relates to a lighting device based on a substation fire alarm. Background Art

[0002] Substations are core facilities in the power system, responsible for the conversion, distribution and transmission of electric energy. They use transformers to convert the high-voltage electric energy generated by power plants into low-voltage electric energy that meets the needs of different users, ensuring that electric energy can be safely and efficiently delivered to thousands of households. Substations are equipped with sophisticated equipment and control systems, including transformers, high-voltage switchgear, medium-voltage switchgear, low-voltage switchgear, protection equipment, and control equipment. These devices work together to achieve precise regulation and monitoring of voltage and current.

[0003] Among them, high-voltage switchgear usually contains more electrical components and complex control systems. The connection and coordination between these components are tighter, but it also increases the possibility of failure. Once a component fails, it may quickly spread to other parts, triggering a chain reaction and increasing the risk of short-circuit fires. At the same time, high-voltage switchgear has been subjected to high voltage and high current shocks for a long time, and it is more prone to short-circuit failures. In addition, under high-voltage environments, the air gap between electrical components is smaller. Once a short circuit occurs, arcs are more likely to occur and develop rapidly. The high temperature and high pressure characteristics of the arc enable it to quickly ignite the surrounding combustible materials, thereby causing a fire.

[0004] In the prior art, when a short circuit fire occurs in a high-voltage switch cabinet of a substation, the alarm is mainly triggered by a photoelectric smoke detector suspended high in the switch cabinet room; however, this traditional detector alarm method requires a certain amount of smoke to be generated before the alarm is triggered, resulting in poor timeliness of the alarm; and there are usually multiple high, medium and low voltage switch cabinets installed in the switch cabinet room of the substation. The staff who hear the alarm cannot promptly identify the high-voltage switch cabinet where the short circuit fire occurs, which will delay the fire extinguishing opportunity to a certain extent; in addition, according to relevant design specifications, lamps should not be arranged directly above the high, medium and low voltage switch cabinets to avoid lamp failures, causing secondary short circuit accidents, and posing a threat to equipment safety; but this results in that after the fire is extinguished, the staff cannot get better lighting guarantee when inspecting the damage inside the high-voltage switch cabinet, thereby affecting the maintenance work.

[0022] The present invention uses the magnetic attraction between the electromagnet and the ferromagnetic metal block. When the power supply air switch in the high-voltage switch cabinet is powered off due to a short circuit or other reasons, the electromagnet immediately loses its magnetism, thereby triggering a series of chain reactions. This design does not need to wait for smoke to be generated, and can respond quickly as long as the circuit is interrupted, greatly improving the timeliness of fire alarms.

[0023] When the electromagnet is disconnected from the ferromagnetic metal block, the sliding support plate slides forward under the rebound force of spring three.

This ensures that in the event of a fire or other emergency, workers can get sufficient lighting when entering the scene, which is convenient for observation and maintenance.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] Embodiment 1

[0043] In order to solve the technical problems in the background technology, a lighting device based on a substation fire alarm is provided as follows:

[0044] Combination Figure 1 to Figure 3 , Figure 5 as well as Fig.13 and Fig.14 As shown, a lighting device based on substation fire alarm is arranged on the top surface of the medium and high voltage switch cabinet 9 of the substation; the device comprises a square structure fixed shell 1 fixedly arranged on the rear side of the top surface of the high voltage switch cabinet 9, a square structure moving shell 2 is attached to the front end surface of the fixed shell 1, and pulling components 3 are elastically attached to the two side surfaces of the moving shell 2 in a horizontal and symmetrical manner, and alarms 8 are fixed to the front ends of the two pulling components 3 in a vertical and symmetrical manner; the two side surfaces of the fixed shell 1 are symmetrically provided with turn-button components 4 for detachably connecting with the moving shell 2; a partition 21 is arranged in the moving shell 2, and a bipolar battery 22 is horizontally embedded in the middle part of the partition 2, the positive and negative poles of the two bipolar batteries 22 are arranged opposite to each other, and the front end electrodes of the two are respectively connected in series with the wiring terminals of the lighting lamp 7 arranged on the front end surface of the moving shell 2 and having an outer frame 71; an electromagnetic push-pull component 5 is arranged in the fixed shell 1;

[0045] The electromagnetic push-pull assembly 5 includes a sliding support plate 51, the ends of which are respectively engaged with the corresponding inner side surfaces of the fixed housing 1 in a transverse sliding manner; a spring 52 is vertically connected between the front elevation of the sliding support plate 51 and the front end surface of the fixed housing 1; at least three ferromagnetic metal blocks 511 are vertically connected to the rear elevation of the sliding support plate 51 at equal intervals along its long side direction, and the ferromagnetic metal blocks 511 are arranged opposite to the electromagnets 53 correspondingly embedded on the rear end surface of the fixed housing 1, and the electromagnets 53 are connected to the power supply air switch in the high-voltage switch cabinet 9 through the power line 531 connected to the rear end thereof;

[0046] The electromagnet 53 is divided into a power-on state and a power-off state. In the power-on state, the electromagnet 53 is magnetically attached to the corresponding ferromagnetic metal block 511, the two screw-on components 4 are clamped with the movable housing 2, and the lighting lamp 7 and the alarm 8 are not turned on; in the power-off state, the electromagnet 53 is separated from the corresponding ferromagnetic metal block 511, and the sliding support plate 51 slides forward under the action of the rebound force of the spring three 52, and simultaneously pushes the two screw-on components 4 to separate from the movable housing 2 and connects the two bipolar batteries 22 to turn on the lighting lamp 7, and then the movable housing 2 slides forward under the action of the rebound force of the two pulling components 3 until the two alarms 8 are synchronously triggered.

[0047] By adopting the above technical solution, the device uses the magnetic attraction between the electromagnet 53 and the ferromagnetic metal block 511. When the power supply air switch in the high-voltage switch cabinet 9 is powered off due to a short circuit or other reasons, the electromagnet 53 immediately loses its magnetism, thereby triggering a series of chain reactions. This design does not need to wait for smoke to be generated, and can respond quickly as long as the circuit is interrupted, greatly improving the timeliness of fire alarms.

[0048] When the electromagnet 53 is disconnected from the ferromagnetic metal block 511, the sliding support plate 51 slides forward under the rebound force of the spring 3 52. This action not only pushes the rotary button assembly 4 to separate from the moving housing 2, but also connects the two bipolar batteries 22, thereby automatically turning on the lighting lamp 7. This ensures that in the event of a fire or other emergency, the staff can get sufficient lighting when entering the scene, which is convenient for observation and maintenance.

[0049] At the same time, the moving housing 2 continues to slide forward under the action of the rebound force of the pulling assembly 3 until the alarm 8 is triggered; this design enables the alarm position to clearly point to the high-voltage switch cabinet 9 where the problem occurs, which helps the staff to quickly locate the source of the fire or the fault point, reducing delays in fire extinguishing and maintenance.

[0050] Embodiment 2

[0051] Combination Figure 3 to Figure 9 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0052] In this embodiment, if Figure 3 , Figure 6 to Figure 8 As shown, the rotary buckle assembly 4 includes a fan plate 41 erected on the outside of the fixed shell body 1, and the fan plate 41 is pivotally connected to a pad 42 vertically connected to the bottom edge of the corresponding side of the fixed shell body 1 through a vertical shaft 411 vertically penetrated at its rear end; a square hole 11 is penetrated at the front end of the side of the fixed shell body 1 and is flush with the top surface of the pad 42, and the bottom edge of the square hole 11 is flush with the top surface of the pad 42, and its top edge is flush with the top surface of the fan plate 41; the inner vertical surface of the rear end of the fan plate 41 is obliquely connected with a collision plate 43 with a gap passing through the square hole 11, and the inner vertical surface of the front end is vertically connected with a clamping column 413, and the clamping column 413 is clamped with the corresponding waist hole 24 through the side of the moving shell body 2; the front vertical surface ends of the sliding support plate 51 are respectively vertically and symmetrically connected with push rods 512, and the push rods 512 are synchronously displaced with the sliding support plate 51, and push the collision plate 43 to rotate outward, so that the clamping column 413 is rotated and separated from the waist hole 24.

[0053] By adopting the above technical solution, the set turn-lock assembly 4 realizes a stable connection between the fixed housing 1 and the moving housing 2 through the combination of the fan plate 41, the vertical shaft 411, the pad 42, the impact plate 43 and the clamping column 413; when the electromagnet 53 is in the energized state, the clamping column 413 is tightly engaged with the waist hole 24 on the side of the moving housing 2 to ensure that the moving housing 2 will not slide accidentally.

[0054] When the electromagnet 53 is powered off and the sliding support plate 51 slides forward under the rebound force of the spring three 52, the push rod 512 pushes the impact plate 43 to rotate outward, thereby rotating the clamping column 413 and separating from the waist hole 24 on the side of the moving housing 2; this process is rapid and reliable, ensuring that the moving housing 2 can be quickly and accurately separated from the fixed housing 1 when needed.

[0055] The design of the turn-button assembly 4 fully considers the needs of automated operation; when the state of the electromagnet 53 changes, the turn-button assembly 4 can automatically complete the connection and separation actions without human intervention, thereby improving the response speed of the device.

[0056] like Figure 7 As shown, the upper portion of the vertical shaft 411 extends out of the top surface of the fan plate 41 and is axially sleeved with a torsion spring 412 , and the upper force arm of the torsion spring 412 is connected to the corresponding side surface of the fixed housing 1 , and the lower force arm is connected to the top surface of the fan plate 41 .

[0057] By adopting the above technical solution, the part extending from the upper part of the vertical shaft 411 is axially sleeved with a torsion spring 412, and the upper and lower force arms of the torsion spring 412 are respectively connected to the side surface of the fixed shell 1 and the top surface of the fan plate 41. This design not only makes the clamping column 413 reliably clamped with the waist hole on the side of the moving shell 2, but also makes the push rod 512 push the impact plate 43 to rotate outward more smoothly; in addition, when the electromagnet 53 is energized, the fan plate 41 can automatically reset under the action of the torsion spring 412, and prepare for the next connection operation.

[0058] like Figure 3 to Figure 6 As shown, the front elevation of the sliding support plate 51 is vertically and symmetrically connected with top columns 513 along the spring three 52 as the central axis, the front end gap of the top column 513 passes through the front end surface of the fixed shell 1 and the rear end surface of the movable shell 2, and the front end of the top column 513 is axially opened with a square groove 5131, and the gap in the square groove 5131 is plugged with a plug column 514, the plug column 514 is arranged opposite to the corresponding rear end electrode of the bipolar battery 22, and the front plugs of the two plug columns 514 are connected in series and conductively via a straight cable 5141 adapted thereto; the top column 513 is displaced synchronously with the sliding support plate 51, and pushes the front plug of the plug column 514 to be plugged with the slot recessed on the rear end electrode of the bipolar battery 22, so as to connect the two bipolar batteries 22 and turn on the lighting lamp 7.

[0059] By adopting the above technical solution, when a short circuit occurs in the high-voltage switch cabinet 9, causing its power air switch to trip and the electromagnet 53 is powered off, the magnetic force between the electromagnet 53 and the ferromagnetic metal block 511 disappears, and the sliding plate 51 slides forward rapidly under the elastic force of the spring three 52; in this process, the sliding plate 51 not only promotes the separation of the rotary buckle assembly 4 and the moving housing 2, but also connects the positive and negative poles of the two bipolar batteries 22 through the linkage of the top column 513 and the plug column 514, thereby automatically turning on the lighting lamp 7; this design does not require human intervention and realizes the functions of rapid response and automatic turning on the lighting lamp 7.

[0060] When the lighting lamp 7 is turned on, the movable housing 2 slides forward under the action of the rebound force of the two pulling components 3, triggering the alarm 8 to be turned on; this design enables lighting and alarm to be carried out synchronously, providing the staff with more comprehensive and timely fire information, helping them to quickly locate the source of the fire and take corresponding fire-fighting measures.

[0061] Since the front plug of the plug column 514 is plugged into the recessed slot on the corresponding rear end electrode of the bipolar battery 22, the plug column 514 will disengage from the square groove 5131 at the front end of the top column 513 as the moving housing 2 moves forward, so that the lighting lamp 7 remains on, providing good lighting conditions for the staff after the fire is extinguished, which helps the staff to observe the damage inside the high-voltage switch cabinet 9 more clearly, thereby performing inspection and maintenance work more accurately, improving the inspection efficiency and accuracy.

[0062] like Figure 4 , Figure 8 and Fig. 9 As shown, a plug hole 5142 is provided on the top surface of the rear insulator of the plug column 514 along its center line, and a stopper assembly 23 is suspended directly above the plug hole 5142;

[0063] The limiting assembly 23 includes a support plate 231 vertically connected to the rear end surface of the moving housing 2, a plug 232 is penetrated by a vertical gap at the front end of the support plate 231, the longitudinal section of the plug 232 is a T-shaped structure, and its bottom is a round head, and is in the same straight line as the socket 5142; a spring 233 is axially sleeved on the vertical part of the plug 232, and the bottom end of the spring 233 is connected to the support plate 231, and the top end is connected to the transverse part of the plug 232; the bottom round head of the plug 232 abuts against the top surface of the rear insulator of the corresponding plug column 514; the bottom round head of the plug 232 is pressed and inserted into the corresponding socket 5142 under the action of the rebound force of the spring 233 as the plug column 514 moves forward to its position.

[0064] By adopting the above technical scheme, the pin 232 in the limit assembly 23 always maintains contact with the top surface of the rear insulator of the plug column 514 under the action of the spring 233; when the sliding support plate 51 pushes the plug column 514 forward so that the front plug is plugged into the slot of the rear electrode of the bipolar battery 22, the bottom round head of the pin 232 will slide on the top surface of the rear insulator of the plug column 514; once the plug column 514 moves forward to its position, the bottom round head of the pin 232 will be quickly pressed into the socket 5142 opened on the top surface of the rear insulator of the plug column 514 under the action of the rebound force of the spring 233, so that the plug column 514 can be smoothly disengaged from the square groove 5131 at the front end of the top column 513; this design not only effectively prevents the plug column 514 from loosening or falling off when subjected to external force or vibration, thereby ensuring the stable connection between the plug column 514 and the bipolar battery 22, and ensuring the reliable turning on of the lighting lamp 7.

[0065] Embodiment 3

[0066] Combination Figure 1 , Figure 3 as well as Figure 10 to Figure 14 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0067] In this embodiment, if Figure 3 , Fig.13 and Fig.14 As shown, the pulling assembly 3 includes a Z-shaped plate 31, the web portion of the Z-shaped plate 31 is slidably attached to the corresponding side of the moving housing 2, and the front plate portion thereof is attached to the corresponding alarm 8; the front end of the side of the moving housing 2 is vertically and symmetrically connected with ear blocks 321, the ear blocks 321 are horizontally slidably connected with the corresponding long strip holes 311 penetrating through the web portion of the Z-shaped plate 31, and a spring 2 32 is horizontally connected between the rear plate portion of the Z-shaped plate 31 and the corresponding ear block 321;

[0068] When the clamping column 413 and the waist hole 24 are not rotated and separated, the ear block 321 is located at the rear end of the corresponding long hole 311, and the spring 2 32 is in a compressed state; when the clamping column 413 and the waist hole 24 are rotated and separated, the ear block 321 slides laterally to the front end of the long hole 311 under the action of the rebound force of the spring 2 32, and simultaneously drives the moving shell 2 to move forward to its position.

[0069] By adopting the above technical solution, the pulling assembly is composed of a Z-shaped plate 31, an ear block 321 and a spring 2 32, which work together to realize the automatic forward movement of the movable housing 2 under the action of the electromagnetic push-pull assembly 5. When the electromagnet 53 is powered off, the sliding support plate 51 of the electromagnetic push-pull assembly 5 slides forward under the push of the spring 3 52, and pushes the collision plate 43 of the rotary buckle assembly 4 through the push rod 512, so that the clamping column 413 is rotated and separated from the waist hole 24 on the side of the movable housing 2. At this time, the ear block 321 slides forward along the long strip hole 311 on the web of the Z-shaped plate 31 under the action of the rebound force of the spring 2 32, driving the movable housing 2 to move forward. The forward movement of the movable housing 2 finally triggers the opening of the alarm 8, realizing the timely alarm of the fire.

[0070] like Figure 1 , Figure 3 , Fig.10 and Fig.11 As shown, the inner housing 6 is inserted into the front gap of the moving housing 2, and the inner housing 6 is open at both ends, and the front end is sealed with the illuminating lamp 7, and the size of the outer frame 71 of the illuminating lamp 7 is the same as the size of the front end surface of the inner housing 6; the front vertical end of the outer frame 71 is vertically connected to a wedge block 73, and the inclined surface of the wedge block 73 is butted against the outer side surface of the corresponding inner housing 6;

[0071] The alarm device 8 comprises a rectangular structure mounting frame 81 vertically connected to the top surface of the high-voltage switch cabinet 9, the top surface of the mounting frame 81 is provided with an audible and visual alarm lamp 82, and the inner facade is provided with an alarm switch 83; the rear end surface of the mounting frame 81 is abutted against the front plate portion corresponding to the Z-shaped plate 31, and the width of the front plate portion is the same as the side width of the moving housing 2; when the moving housing 2 moves forward into position, the wedge block 73 triggers the alarm switch 83, causing the audible and visual alarm lamp 82 to turn on.

[0072] By adopting the above technical solution, the inner housing 6 is used as the mounting carrier of the illuminating lamp 7, and its two ends are open for easy installation and heat dissipation of the illuminating lamp 7. When the electromagnetic push-pull assembly 5 is triggered and the movable housing 2 moves forward, the inner housing 6 moves forward accordingly, so that the illuminating lamp 7 can be closer to the cabinet door 91 of the high-voltage switch cabinet 9, thereby better illuminating the interior of the high-voltage switch cabinet 9, providing a clear field of vision for the staff, and facilitating maintenance or fire extinguishing operations.

[0073] The wedge block 73 is a key component for triggering the alarm switch 83. Its inclined surface design enables the wedge block 73 to gradually approach and contact the alarm switch 83 during the forward movement of the movable housing 2, and finally trigger the turning on of the sound and light alarm light 82. This design realizes the linkage between the lighting lamp 7 and the alarm 8, that is, when the lighting lamp 7 is turned on to illuminate the scene, the alarm 8 also emits a sound and light alarm at the same time to remind the staff to pay attention to the fire situation.

[0074] The inclined surface design of the wedge block 73 makes the triggering process smoother and more reliable; as the moving housing 2 gradually moves forward, the inclined surface of the wedge block 73 gradually contacts and compresses the triggering mechanism of the alarm switch 83 until the triggering condition is reached; this design reduces the risk of component damage caused by sudden impact and improves the reliability of the triggering process.

[0075] like Figure 12 to Figure 14 As shown, the alarm switch 83 includes a second plug 831 which is connected with the inner surface of the installation frame 81 through a vertical gap. The outer end of the second plug 831 is set as a round head, and the inner end thereof is axially connected with a plug piece 832; a fourth spring 833 is axially sleeved on the second plug 831, and one end of the fourth spring 833 is connected to the plug piece 832, and the other end thereof is connected to the inner surface of the installation frame 81; a socket piece 834 is suspended opposite to the inner side of the plug piece 832 in the positive direction, and the socket piece 834, the sound and light alarm lamp 82 and the battery 835 arranged in the installation frame 81 are connected in series in sequence through the corresponding wires 836; the wedge block 73 moves forward to the position with the moving housing 2, and presses the second plug 831 inward along its inclined surface until the outer round head of the second plug 831 abuts against the outer surface of the inner housing 6, causing the spring four 833 to extend, and the plug piece 832 is connected with the socket piece 834 to turn on the sound and light alarm lamp 82.

[0076] By adopting the above technical solution, the alarm switch 83 adopts a combination design of the second plug 831, the plug piece 832, the socket piece 834 and the fourth spring 833, so that when a fire occurs, the movable housing 2 moves forward and drives the wedge block 73 to contact the second plug 831; in this process, the second plug 831 gradually moves inward under the inward contact pressure of the inclined surface of the wedge block 73 until the round head of its outer end abuts against the outer surface of the inner housing 6. At this time, the fourth spring 833 is stretched, and the plug piece 832 is connected with the socket piece 834, thereby quickly turning on the sound and light alarm light 82. This design ensures that the alarm can be triggered quickly when a fire occurs, and improves the timeliness of the alarm. The outer end of the second plug 831 is set as a round head, which is convenient for the wedge block 7 to contact and slide with it.

[0077] Embodiment 4

[0078] Combination Figure 5 , Fig.10 , Fig.11 and Fig.15 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0079] In this embodiment, if Figure 5 , Fig.10 , Fig.15As shown, the wiring terminal of the illuminating lamp 7 is connected in series with the corresponding front electrode of the bipolar battery 22 through a telescopic spiral cable 221 adapted thereto; the bottom edge of the outer frame 71 of the illuminating lamp 7 is pivotally connected to the damping shaft 61 arranged at the bottom edge of the inner shell 6; the rear end of the side surface of the inner shell 6 is symmetrically penetrated with a second plug hole 62, and the second plug hole 62 and the outer end round head of the second plug pin 831 are on the same straight line; after the moving shell 2 is moved forward to the position, the inner shell 6 is connected through The external force is pulled out from the moving housing 2 to the edge of the top surface of the high-voltage switch cabinet 9, and the outer round head of the second pin 831 is pressed and inserted into the corresponding second socket 62 under the action of the rebound force of the fourth spring 833. The plug piece 832 is separated from the socket piece 834 under the action of the rebound force of the fourth spring 833 to turn off the sound and light alarm light 82; after the cabinet door 91 of the high-voltage switch cabinet 9 is opened, the lighting lamp 7 can be flipped within 180° along the damping shaft 61 by external force.

[0080] By adopting the above technical solution, the combined design of the telescopic spiral cable 221, the damping shaft 61 and the second socket 62 enables the staff to more conveniently operate the lighting lamp 7 and the alarm 8 when inspecting the damage inside the high-voltage switch cabinet. The flexible adjustment and stable lighting of the lighting lamp 7 provide good lighting guarantee for the inspection work; and the intelligent control of the alarm avoids noise interference during the inspection process, and improves the efficiency and safety of the inspection work.

[0081] Among them, the telescopic spiral cable 221 can ensure that after the inner shell 6 is manually pulled outward, the lighting lamp 7 still maintains a power supply connection with the bipolar battery 22; the inner shell 6 can be automatically pulled out of the shell 2 to the edge of the top surface of the high-voltage switch cabinet 9, which can further improve the lighting effect inside the high-voltage switch cabinet 9, and the design of the damping shaft 61 enables the lighting lamp 7 to be flipped within a certain range along its axis under the action of external force. This design not only facilitates the staff to adjust and use the lighting lamp 7, but also can provide a more uniform lighting effect at different angles; at the same time, the damping shaft 61 also has a certain damping force, which can keep the lighting lamp 7 in a stable position after flipping, and avoid shaking of the lighting lamp 7 due to vibration or external force.

[0082] The matching design of the second socket 62 and the outer round head of the second plug 831 realizes the intelligent control of the lighting lamp 7 and the alarm 8. When the moving housing 2 moves forward to the right position, the inner housing 6 can be pulled out of the moving housing 2 by external force, and the outer round head of the second plug 831 is pressed and inserted into the corresponding socket 62 under the action of the rebound force of the fourth spring 833. In this process, the plug piece 832 is separated from the socket piece 834, thereby turning off the sound and light alarm lamp 82. This design not only simplifies the turning off operation of the sound and light alarm lamp 82, but also avoids noise interference during the maintenance process.

[0083] like Fig.10 and Fig.11 As shown, at least two straight plates 72 are vertically arranged on the top edge of the outer frame 71 of the lighting lamp 7 , and the straight plates 72 are gap-engaged with the corresponding straight grooves 63 recessed on the edge of the top surface of the inner shell 6 .

[0084] By adopting the above technical solution, the gap-connecting design between the straight plate 72 and the straight groove 63 provides a stable support and positioning for the position of the lighting lamp 7 on the inner shell 6, and better ensures that it is not easy to produce misaligned rotation along the damping shaft 61 due to external vibration under normal circumstances.

[0085] The working principle and use process of the present invention:

[0086] When the present invention is in use, under normal circumstances, the electromagnet 53 is energized, the ferromagnetic metal block 511 is magnetically attached, the fan plate 41 of the turn button assembly 4 remains in a state of being engaged with the moving housing 2, and the lighting lamp 7 and the alarm 8 are not turned on. When a short circuit occurs in the high-voltage switch cabinet 9, the electromagnet 53 loses power, the ferromagnetic metal block 511 is separated from the electromagnet 53, the sliding support plate 51 slides forward under the action of the spring 3 52, and the push rod 512 is pushed to rotate the striker 43, and the clamping column 413 of the turn button assembly 4 is separated from the waist hole 24, unlocking the moving housing 2.

[0087] At the same time, the sliding support plate 51 pushes the top column 513 forward, and the plug column 514 is correspondingly inserted into the rear end slot of the bipolar battery 22, connecting the circuits of the two bipolar batteries 22, and the lighting lamp 7 lights up. The movable housing 2 slides forward under the rebound force of the spring 2 32 of the pulling component 3 until the alarm 8 is triggered, and the sound and light alarm lamp 82 turns on to indicate the fire location.

[0088] If the high-voltage switch cabinet 9 needs to be repaired after the fire is extinguished, the staff can pull the inner housing 6 out of the movable housing 2, so that the round head of the second plug pin 831 is pressed into the second socket 62, and the spring 4 833 rebounds to pull the plug piece 832 and the socket piece 834 apart, turning off the sound and light alarm lamp 82. At this time, the lighting lamp 7 is still powered by the two bipolar batteries 22, and the staff can get better lighting by turning over the lighting lamp 7, which is convenient for maintenance work.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
