Description

Technical Field

[0001] This invention belongs to the field of power fire emergency response technology, specifically relating to an emergency response device and method for power fire protection system failures. Background Technology

[0002] Water curtains are typically installed around important electrical equipment in large power plants and substations to form fire protection systems. These water curtains usually consist of water curtain nozzles, deluge alarm valve assemblies, water supply and distribution pipes, control valves, and water flow alarm devices. When needed, the water curtain forms a wall of water to prevent the spread of fire and smoke, thus providing fire protection and cooling.

[0003] However, because fire water curtains are installed over a large area and used infrequently, the frequency of replacing aging parts during routine maintenance is low. Consequently, there is a lack of necessary emergency response devices to assist in completing electrical firefighting operations when the equipment cannot be activated normally in the event of an emergency fire incident.

[0004] Based on this, an emergency handling device and method for power fire protection system failures are proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an emergency handling device and method for power fire protection system failures, in order to address the shortcomings of the prior art mentioned above.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, there is an emergency handling device for a power fire protection system failure, comprising a fire emergency water supply pipe installed in the ground below the power fire water curtain and an emergency handling unit installed on the fire emergency water supply pipe.

[0008] The fire emergency water supply pipes are provided in multiple ways and are arranged in parallel with each other. Each fire emergency water supply pipe is also provided with multiple emergency treatment units, which are installed at equal intervals on the fire emergency water supply pipe.

[0009] The emergency response unit includes a base frame, vertical frames, an emergency response plate, a heat-conducting rod, and an emergency sprinkler head mechanism. The base frame is fixed to the fire emergency water pipe, and two vertical frames are symmetrically fixed on the base frame. The vertical frames are U-shaped, and an emergency response plate is rotatably connected to the top of each vertical frame. The bottom end of the emergency response plate is connected to the vertical frame via a heat-conducting rod, and an emergency response pin is provided at the connection between the heat-conducting rod and the vertical frame. A through hole is provided in the middle of the base frame, and an emergency sprinkler head mechanism is sleeved in the through hole. The fire sprinkler head in the emergency sprinkler head mechanism is connected to the fire emergency water supply pipe through a pipeline.

[0010] As a further explanation of the present invention, the emergency response plate includes a connecting seat, a heat-conducting plate, a heat-conducting seat, and a counterweight. A horizontal pin is fixed near the top of the vertical frame. The connecting seat is rotatably connected to the outside of the horizontal pin. A heat-conducting plate is fixed to the other end of the connecting seat. A heat-conducting seat is fixed to the bottom surface of the other end of the heat-conducting plate. The top end of the heat-conducting rod is rotatably connected to the heat-conducting seat. A counterweight is fixed to the outer end of the heat-conducting plate.

[0011] As a further explanation of the present invention, the transverse pin is a high-temperature resistant steel pin, and the emergency response pin is a hot-melt plastic pin.

[0012] As a further explanation of the present invention, the emergency response plate is coated with a thermally conductive coating in the area above the heat-conducting plate. When the emergency response plate is in a horizontal state, the top surface of the thermally conductive coating is on the same horizontal plane as the top surface of the vertical frame.

[0013] As a further explanation of the present invention, the distance between the two vertical frames is the same as the sum of the lengths of the two emergency response plates.

[0014] As a further explanation of the present invention, the emergency sprinkler head mechanism includes a connecting pipe, a support base, a fire sprinkler head, and a touch switch plate. The connecting pipe is sleeved in the through hole in the middle of the base frame. The top of the connecting pipe is fixed with the support base, and at least three fire sprinkler heads are fixed to the top of the support base. The fire sprinkler heads spray vertically upwards, and each fire sprinkler head has a different spray direction. The liquid inlet of each fire sprinkler head is connected to the connecting pipe. The bottom of the connecting pipe is also fixed with a touch switch plate. The base frame has a touch point installed at the top of the through hole. The touch switch plate and the touch point cooperate to complete the on / off control of the fire sprinkler head.

[0015] As a further explanation of the present invention, a limiting groove is provided on the vertical side of the through hole of the base frame, and the touch switch plate is slidably connected in the limiting groove.

[0016] As a further explanation of the present invention, a connecting hole is provided below each emergency treatment unit on the fire emergency water supply pipe, and a folded flexible hose is fixedly connected to the top of the connecting hole, and the bottom end of the connecting pipe is connected to the folded flexible hose.

[0017] As a further explanation of the present invention, two triggering mechanisms are symmetrically installed between the support base and the inner top end of the base frame. The triggering mechanism includes a triggering rope and a V-shaped spring. The top end of the V-shaped spring is installed on the bottom surface of the support base, and the bottom end of the V-shaped spring is installed on the inner top end of the base frame. The triggering rope is installed at the bend of the V-shaped spring, and the other end of the triggering rope is installed inside the vertical frame. The straight line of the triggering rope is at least 1 cm higher than the tangent line at the bottom end of the working circular surface of the emergency response plate.

[0018] The second aspect is an emergency handling method for a fault emergency handling device of a power fire protection system, comprising the following steps:

[0019] S1. First, dig several grooves in the ground below the electric fire water curtain for the installation of emergency treatment units. Then, first install the fire emergency water supply pipe on the inner bottom surface of the groove. Then, install the emergency treatment units at equal intervals on the fire emergency water supply pipe. Then, install baffles around the emergency treatment units and backfill the area outside the baffles in the groove to the same height as the emergency treatment units.

[0020] S2. In the event of an electrical fire, if the fire water curtain above the emergency response unit fails to function properly and cool down, the temperature in the space above the emergency response unit will rise. The heat will be conducted through the heat-conducting coating on the surface of the emergency response plate to the heat-conducting plate, and then through the heat-conducting base and heat-conducting rod to the emergency response pin. When the temperature of the heat-conducting rod exceeds the melting temperature of the emergency response pin, the emergency response pin will melt. At this time, the support force at the bottom of the heat-conducting rod will disappear. Under the action of the counterweight at the outer end of the emergency response plate, the emergency response plate will descend and the emergency response will begin.

[0021] S3. When the emergency response plate descends to the height of the trigger rope, the trigger rope is cut by the shearing surface formed by the emergency response plate and the bottom surface of the vertical frame. After the trigger rope breaks, the lateral tension of the V-shaped spring disappears. Under the action of the V-shaped spring force, the support seat moves upward. The support seat moves upward until it contacts the touch switch plate and the touch point, which controls the opening of the fire sprinkler head. At this time, due to the descent of the emergency response plate, the obstruction space between the two vertical frames is opened, and the fire sprinkler head and the fire emergency water supply pipe can be used to complete the emergency sprinkler cooling treatment of the electric fire protection.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. This invention utilizes a fire emergency water supply pipe installed on the ground below a power fire water curtain and emergency handling units installed on the fire emergency water supply pipe. Multiple fire emergency water supply pipes are installed in parallel with each other, and each fire emergency water supply pipe is independently connected to an external fire water storage tank, thus ensuring that the fire emergency water supply pipe can independently complete fire water supply operations. Multiple emergency handling units are also installed on each fire emergency water supply pipe, with the emergency handling units installed at equal intervals on the fire emergency water supply pipe. These emergency handling units can handle emergency fire handling operations when the fire water curtain malfunctions and cannot be triggered.

[0024] 2. The base frame of the emergency response unit in this invention is fixed to the fire emergency water pipe, and two vertical frames are symmetrically fixed on the base frame. An emergency response plate is rotatably connected to the top of each vertical frame. The emergency response plate includes a connecting seat, a heat-conducting plate, a heat-conducting seat, and a counterweight. A horizontal pin is fixed to the top of each vertical frame, and the connecting seat is rotatably connected to the outside of the horizontal pin. A heat-conducting plate is fixed to the other end of the connecting seat, and a heat-conducting seat is fixed to the bottom surface of the other end of the heat-conducting plate. The top end of a heat-conducting rod is rotatably connected to the heat-conducting seat, and a counterweight is fixed to the outer end of the heat-conducting plate. The bottom end of the emergency response plate is connected to the vertical frame through the heat-conducting rod. The connection between the heat-conducting rod and the vertical frame is... An emergency response pin is installed. The emergency response plate is coated with a thermally conductive coating in the area above the heat-conducting plate. In the event of an electrical fire, if the fire water curtain above the emergency response unit fails to function properly for cooling, the temperature in the space above the emergency response unit will rise. The heat will be conducted through the thermally conductive coating on the surface of the emergency response plate to the heat-conducting plate, and then sequentially through the heat-conducting base and heat-conducting rod to the emergency response pin. When the temperature of the heat-conducting rod exceeds the melting point of the emergency response pin, the emergency response pin will melt. At this time, the supporting force at the bottom of the heat-conducting rod will disappear. Under the action of the counterweight at the outer end of the emergency response plate, the emergency response plate will descend, thus enabling the activation of the emergency response system.

[0025] 3. This invention features an emergency sprinkler head mechanism fitted into a through hole in the center of the base frame. The fire sprinkler heads within this mechanism are connected to an emergency fire water supply pipe via pipelines. The emergency sprinkler head mechanism includes a connecting pipe, a support base, fire sprinkler heads, and a touch switch panel. The connecting pipe is fitted into the through hole in the center of the base frame. A support base is fixed to the top of the connecting pipe, and at least three fire sprinkler heads are fixed to the top of the support base. The fire sprinkler heads spray vertically upwards, and each fire sprinkler head has a different spray direction. When the emergency response panel descends to the touch switch panel... When the trigger rope is at the specified height, the trigger rope is cut by the shearing surface formed by the emergency response plate and the bottom surface of the vertical frame. After the trigger rope breaks, the lateral tension of the V-shaped spring disappears, and the support seat moves upward under the action of the V-shaped spring force. The support seat moves upward until it contacts the touch switch plate and the touch point, which controls the opening of the fire sprinkler head. At this time, due to the descent of the emergency response plate, the obstruction space between the two vertical frames is opened, and the fire sprinkler head and the fire emergency water supply pipe can be used to complete the emergency sprinkler cooling treatment of the electric fire protection system.

Detailed Implementation

[0031] 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.

[0032] like Figure 1-3As shown, the present invention provides a technical solution: an emergency handling device for a power fire protection system failure, comprising a fire emergency water supply pipe 1 installed in the ground below the power fire water curtain and an emergency handling unit 2 installed on the fire emergency water supply pipe 1;

[0033] The fire emergency water supply pipe 1 is provided in multiple ways, and the multiple fire emergency water supply pipes 1 are arranged in parallel with each other. Each fire emergency water supply pipe 1 is independently connected to an external fire water storage tank, so as to ensure that the fire emergency water supply pipe 1 can independently complete the fire water supply operation.

[0034] Each of the fire emergency water supply pipes 1 is also equipped with multiple emergency handling units 2. The emergency handling units 2 are installed at equal intervals on the fire emergency water pipes 1. The emergency handling units 2 can complete the emergency fire handling operation when the fire water curtain fails to be triggered due to abnormality.

[0035] The emergency response unit 2 includes a base frame 3, vertical frames 4, an emergency response plate 5, a heat-conducting rod 6, and an emergency sprinkler head mechanism 7. The base frame 3 is fixed on the fire emergency water pipe 1, and two vertical frames 4 are symmetrically fixed on the base frame 3. The vertical frames 4 are U-shaped frames, which can support the emergency response plate 5, and the space between the two vertical frames 4 is the installation and use space for the emergency sprinkler head mechanism 7.

[0036] Meanwhile, the four support points of the two vertical frames 4 can improve the overall top support of the emergency response unit 2, and avoid the accidental activation of the emergency response panel 5 due to stepping during use, thus broadening the application scenarios of the emergency response unit.

[0037] An emergency response plate 5 is rotatably connected near the top of the vertical frame 4. The emergency response plate 5 can complete the emergency activation operation of the emergency treatment unit 2.

[0038] The emergency response plate 5 includes a connecting seat 51, a heat-conducting plate 52, a heat-conducting seat 53, and a counterweight 54. A horizontal pin 41 is fixed inside the vertical frame 4 near the top. The connecting seat 51 is rotatably connected to the outside of the horizontal pin 41. The horizontal pin 41 can complete the operation of rotatably connecting one end of the emergency response plate 5 to the top of the vertical frame 4, thereby facilitating the deployment of the emergency unit 2.

[0039] The other end of the connecting seat 51 is fixed with a heat-conducting plate 52. The heat-conducting plate 52 is used to complete the heat conduction in the space above the heat-conducting plate 52. In the event of a fire, if the fire water curtain set up around the electrical equipment fails to start in time, the temperature in the space above the emergency treatment unit 2 installed on the ground below the power fire water curtain will rise rapidly. The heat can be quickly conducted to the emergency treatment unit 2 through the heat-conducting plate 52, completing the transmission of external high temperature information to the emergency treatment unit 2, thereby completing the start-up of the emergency treatment unit 2.

[0040] A heat-conducting seat 53 is fixed to the bottom surface of the other end of the heat-conducting plate 52. The top end of the heat-conducting rod 6 is rotatably connected inside the heat-conducting seat 53. The heat-conducting seat 53 can cooperate with the heat-conducting plate 52 to complete the rapid conduction of heat.

[0041] The bottom end of the emergency response plate 5 is connected to the vertical frame 4 via a heat-conducting rod 6. An emergency response pin 42 is provided at the connection between the heat-conducting rod 6 and the vertical frame 4. The horizontal pin 41 is made of high-temperature resistant steel, and the emergency response pin 42 is made of hot-melt plastic. When heat is transferred to the heat-conducting rod 6 through the heat-conducting seat 53, the appropriate hot-melt plastic pin model with the appropriate hot-melt temperature is selected according to the required emergency treatment temperature threshold. When the temperature inside the heat-conducting rod 6 reaches the emergency treatment response temperature, the hot-melt plastic pin melts and breaks. At this time, the bottom end of the heat-conducting rod 6 is disconnected from the vertical frame 4.

[0042] A counterweight 54 is fixed to the outer end of the heat-conducting plate 52. Under the action of the counterweight 54, one side of the counterweight 54 of the heat-conducting plate 52 makes a downward circular motion with the transverse pin 41 as the center, thereby enabling the opening of the area above the emergency treatment unit 2.

[0043] The emergency response plate 5 is coated with a thermally conductive coating 55 in the area above the heat-conducting plate 52. When the emergency response plate 5 is in a horizontal state, the top surface of the thermally conductive coating 55 is on the same horizontal plane as the top surface of the vertical frame 4. The thermally conductive coating 55 can quickly complete the heat conduction, thereby improving the sensitivity of emergency activation and facilitating the timely response of the emergency handling unit 2.

[0044] The distance between the two vertical frames 4 is the same as the sum of the lengths of the two emergency response plates 5, which facilitates the use of the two emergency response plates 5 together.

[0045] In the event of a specific electrical fire, if the fire water curtain above the emergency response unit 2 fails to function properly and cool down, the temperature in the space above the emergency response unit 2 will rise. The heat will be conducted through the heat-conducting coating 55 on the surface of the emergency response plate 5 to the heat-conducting plate 52, and then through the heat-conducting seat 53 and the heat-conducting rod 6 to the emergency response pin 42.

[0046] When the temperature of the heat-conducting rod 6 exceeds the melting temperature of the emergency response pin 42, the emergency response pin 42 melts. At this time, the supporting force at the bottom of the heat-conducting rod 6 disappears, and the emergency response plate 5 descends under the action of the counterweight block 54 at the outer end of the emergency response plate 5, thus completing the opening of the emergency treatment.

[0047] The base frame 3 has a through hole in the middle, and an emergency sprinkler head mechanism 7 is sleeved in the through hole. The fire sprinkler head 73 in the emergency sprinkler head mechanism 7 is connected to the fire emergency water supply pipe 1 through a pipeline.

[0048] The emergency sprinkler head mechanism 7 includes a connecting pipe 71, a support base 72, a fire sprinkler head 73, and a touch switch panel 74. The connecting pipe 71 is sleeved in the through hole in the middle of the base frame 3, and the support base 72 is fixed at the top of the connecting pipe 71.

[0049] At least three fire sprinkler heads 73 are fixed to the top of the support base 72. The fire sprinkler heads 73 spray water vertically upwards, and each fire sprinkler head 73 sprays water in a different direction, so that water can be sprayed quickly into the circumferential space after the fire sprinkler head 73 is activated, and the operation of rapid cooling can be completed.

[0050] Each of the fire sprinkler heads 73 has an inlet connected to a connecting pipe 71. A touch switch plate 74 is fixed at the bottom of the connecting pipe 71. A limit groove 31 is provided on the vertical side of the through hole of the base frame 3. The touch switch plate 74 is slidably connected in the limit groove 31.

[0051] The base frame 3 has a touch point installed at the top of the through hole, and the touch switch plate 74 works with the touch point to control the on / off of the fire sprinkler head 73.

[0052] Each emergency treatment unit 2 has a connecting hole 11 on the fire emergency water supply pipe 1. A folded hose 12 is fixedly connected to the top of the connecting hole 11. The bottom end of the connecting pipe 71 is connected to the folded hose 12. The lifting and lowering operation of the emergency sprinkler head mechanism 7 can be completed through the folded hose 12.

[0053] Two triggering mechanisms 8 are symmetrically installed between the support base 72 and the inner top of the base frame 3. The triggering mechanism 8 includes a triggering rope 81 and a V-shaped spring 82. The top of the V-shaped spring 82 is installed on the bottom surface of the support base 72, and the bottom of the V-shaped spring 82 is installed on the inner top of the base frame 3. The triggering rope 81 is installed at the bend of the V-shaped spring 82. The other end of the triggering rope 81 is installed inside the vertical frame 4, and the straight line of the triggering rope 81 is at least 1 cm higher than the line of the bottom tangent of the working circular surface of the emergency response plate 5.

[0054] In practical use, when the emergency response plate 5 is activated, the counterweight 54 of the heat conduction plate 52 moves downward in a circular motion with the transverse pin 41 as the center. When the counterweight 54 descends rapidly to the height of the trigger rope 81, the trigger rope 81 is cut by the shearing surface formed between the tail end of the counterweight 54 and the bottom end of the vertical frame 4. After the trigger rope 81 breaks, the transverse tension of the V-shaped spring 82 disappears. Under the action of the elastic force of the V-shaped spring 82, the support seat 72 moves upward. The support seat 72 moves upward until it contacts the touch switch plate 74 and the touch point, which controls the opening of the fire sprinkler head 73.

[0055] Moreover, at this time, due to the descent of the emergency response plate 5, the obstruction space between the two vertical frames can be fully opened. At the same time, with the upward movement of the support base 72, the three fire sprinkler heads 73 at the top of the support base 72, which face different directions, can expand the range of fire sprinkler spraying. After the fire sprinkler heads 73 are activated, they can quickly spray water into the circumferential space, which can improve the cooling efficiency and complete the rapid cooling operation.

[0056] The emergency handling method for the above-mentioned emergency handling device for electrical fire protection system failure includes the following steps:

[0057] S1. First, dig multiple grooves in the ground below the electric fire water curtain for the installation of emergency treatment units 2. Then, according to the coverage area of ​​the electric fire water curtain, select an area of ​​appropriate size for the installation of emergency treatment units 2. Calculate the number of emergency treatment units 2 to be installed by the installation density of emergency treatment units 2 in this area. Then, calculate the installation density of fire emergency water supply pipe 1 by the number of emergency treatment units 2 installed. Finally, carry out the sinking excavation in the area where the fire emergency treatment units 2 are installed.

[0058] After excavating the installation groove, first install the fire emergency water supply pipe 1 on the inner bottom surface of the groove, then install the emergency treatment unit 2 at equal intervals on the fire emergency water supply pipe 1, then install baffles around the emergency treatment unit 2, and backfill the area outside the baffles in the groove to the same height as the emergency treatment unit 2.

[0059] S2. In the event of an electrical fire, if the fire water curtain above the emergency response unit 2 fails to function properly and cool down, the emergency response unit 2 will collect the external temperature information and then respond to carry out fire emergency response operations.

[0060] The heat in the space above the specific emergency response unit 2 increases, causing the temperature of the entire space to rise. The heat in the space above the emergency response unit 2 can be quickly conducted to the emergency response unit 2 through the heat conduction plate 52, completing the transfer of external high temperature information to the emergency response unit 2, thereby activating the emergency response unit 2.

[0061] That is, the heat is conducted through the heat-conducting coating 55 on the surface of the emergency response plate 5 to the heat-conducting plate 52, and then through the heat-conducting base 53 and the heat-conducting rod 6 to the emergency response pin 42.

[0062] When the temperature of the heat-conducting rod 6 exceeds the melting temperature of the emergency response pin 42, the emergency response pin 42 melts, and the bottom end of the heat-conducting rod 6 is disconnected from the vertical frame 4. At this time, the supporting force at the bottom end of the heat-conducting rod 6 disappears, and the emergency response plate 5 descends under the action of the counterweight 54 at the outer end of the emergency response plate 5. Specifically, one side of the counterweight 54 of the heat-conducting plate 52 makes a downward circular motion with the transverse pin 41 as the center, thereby completing the opening of the area above the emergency treatment unit 2 and starting emergency treatment.

[0063] S3. When the emergency response plate 5 descends to the height of the trigger rope 81, the trigger rope 81 is cut by the shearing surface formed by the emergency response plate 5 and the bottom surface of the vertical frame 4. After the trigger rope 81 breaks, the lateral tension of the V-shaped spring 82 disappears. Under the action of the elastic force of the V-shaped spring 82, the support seat 72 moves upward. The support seat 72 moves upward until it contacts the touch switch plate 74 and the touch point, which controls the opening of the fire sprinkler head 73. At this time, due to the descent of the emergency response plate 5, the obstruction space between the two vertical frames is opened. The fire sprinkler head 73 and the fire emergency water supply pipe 1 can then be used to complete the emergency sprinkler cooling treatment of the electric fire protection system.

[0064] At this time, due to the descent of the emergency response plate 5, the obstruction space between the two vertical frames can be fully opened. At the same time, with the upward movement of the support base 72, the three fire sprinkler heads 73 at the top of the support base 72, which face different directions, can expand the range of fire sprinkler spraying. After the fire sprinkler heads 73 are activated, they can quickly spray water into the circumferential space, which can improve the cooling efficiency and complete the rapid cooling operation.

[0065] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

When the emergency response plate (5) is in a horizontal state, the top surface of the thermally conductive coating (55) is on the same horizontal plane as the top surface of the vertical frame (4).

5. The emergency handling device for a power fire protection system fault according to claim 1, characterized in that, The distance between the two vertical frames (4) is the same as the sum of the lengths of the two emergency response plates (5).

6. The emergency handling device for a power fire protection system fault according to claim 1, characterized in that, A limiting groove (31) is provided on the vertical side of the through hole of the base frame (3), and the touch switch plate (74) is slidably connected in the limiting groove (31).

7. The emergency handling device for a power fire protection system fault according to claim 1, characterized in that, The fire emergency water supply pipe (1) has a connecting hole (11) below each emergency treatment unit (2). The top of the connecting hole (11) is fixedly connected to a folded hose (12), and the bottom of the connecting pipe (71) is connected to the folded hose (12).

8. The emergency handling device for a power fire protection system according to claim 1, characterized in that, Two triggering mechanisms (8) are symmetrically installed between the support base (72) and the inner top of the base frame (3). The triggering mechanism (8) includes a triggering rope (81) and a V-shaped spring (82). The top of the V-shaped spring (82) is installed on the bottom surface of the support base (72), and the bottom of the V-shaped spring (82) is installed on the inner top of the base frame (3). The triggering rope (81) is installed at the bend of the V-shaped spring (82). The other end of the triggering rope (81) is installed inside the vertical frame (4), and the straight line of the triggering rope (81) is at least 1 cm higher than the line of the bottom tangent of the working circle of the emergency response plate (5).

9. An emergency handling method for a fault emergency handling device of a power fire protection system, characterized in that, Includes the following steps: S1. First, dig several grooves in the ground below the electric fire water curtain for the installation of emergency treatment units (2). Then, first install the fire emergency water supply pipe (1) on the inner bottom surface of the groove. Then, install the emergency treatment units (2) on the fire emergency water supply pipe (1) at equal intervals. Then, install baffles around the emergency treatment units (2) and backfill the area outside the baffles in the groove until it is backfilled to the same height as the emergency treatment units (2). S2. In the event of an electrical fire, when the fire water curtain above the emergency response unit (2) fails to work properly to cool down, the temperature in the space above the emergency response unit (2) rises. The heat is conducted through the heat-conducting coating (55) on the surface of the emergency response plate (5) to the heat-conducting plate (52), and then through the heat-conducting seat (53) and the heat-conducting rod (6) to the emergency response pin (42). When the temperature of the heat-conducting rod (6) is greater than the melting temperature of the emergency response pin (42), the emergency response pin (42) melts. At this time, the support force at the bottom of the heat-conducting rod (6) disappears. Under the action of the counterweight (54) at the outer end of the emergency response plate (5), the emergency response plate (5) descends and begins emergency treatment. S3. When the emergency response plate (5) descends to the height of the trigger rope (81), the trigger rope (81) is cut off under the action of the shear surface formed by the emergency response plate (5) and the bottom surface of the vertical frame (4). After the trigger rope (81) breaks, the lateral tension of the V-shaped spring (82) disappears. Under the action of the elastic force of the V-shaped spring (82), the support seat (72) moves up. The support seat (72) moves up to the touch switch plate (74) and the touch point, so that the fire sprinkler head (73) can be turned on. At this time, due to the descent of the emergency response plate (5), the shielding space between the two vertical frames is opened, so that the fire sprinkler head (73) and the fire emergency water supply pipe (1) can be used to complete the emergency spraying and cooling treatment of electric fire protection.
