Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and more specifically, to a power equipment positioning device and method based on a power network scenario. Background Technology

[0002] Power equipment is a power production and consumption system composed of power generation, transmission, transformation, distribution and consumption. It converts primary energy from nature into electricity through power generation devices, and then supplies the electricity to users through transmission, transformation and distribution. Power equipment includes many components, and sometimes installation rooms or cabinets are set up to install and manage the various components in a unified manner.

[0003] Depending on the usage requirements, the structure of the power equipment installation room varies in size and can be mobile. In some mountainous or remote areas, construction and maintenance personnel may not be familiar with the location of the equipment. In such cases, it is necessary to install a positioning system on the equipment to facilitate the location of the equipment by maintenance personnel.

[0004] However, the existing positioning of power equipment only provides a positioning point for the equipment, and cannot display the actual position of each component in the power equipment. When maintenance personnel arrive at the site, they cannot find faulty or lost components in time, which is not conducive to dealing with emergency situations involving components. Summary of the Invention

[0005] The present invention provides a power equipment positioning device and method based on a power network scenario, which aims to solve the problem that existing power equipment positioning methods cannot locate and display the actual position of each component in the power equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power equipment positioning device based on a power network scenario, comprising a power equipment room, wherein all components installed in the power equipment room are located on the same plane, and a positioning protection device is provided on one side of the power equipment room opposite to the aforementioned plane. The positioning protection device is equipped with a signal receiver and a safety protection module. Each component is equipped with a signal transmitter for identifying itself, and the signal emitted by the signal transmitter is continuously received and identified by the signal receiver. The positioning protection device includes a mounting shell, in which a processor, a GPS module, and a communication module are installed. The GPS module is used to locate the entire device, and the communication module... The signal transmitter is equipped with a temperature sensing module to communicate with the external network. When the electrical appliance malfunctions and the temperature becomes too high, the signal is detected by the signal receiver. The safety protection module includes a fire extinguishing canister and a heat dissipation actuator. The fire extinguishing canister stores dry powder and is sprayed to extinguish the fire in the event of an internal fire in the power equipment room. The heat dissipation actuator is fixedly installed in a mounting shell, which is located at the heat dissipation and exhaust window of the power equipment room. The power equipment room is also equipped with an air exchange port. The heat dissipation actuator is equipped with an exhaust rotating body. The heat dissipation actuator is a motor structure, and the exhaust rotating body is an exhaust blade structure. The mounting shell is equipped with exhaust holes, so that the interior of the power equipment room can be vented and cooled in real time.

[0007] In a preferred embodiment, the signal transmitter is an infrared signal transmitting module, the signal receiver is an infrared signal receiving module, and the temperature sensing module on the signal transmitter includes a temperature control switch, which shuts off the signal transmitter when the temperature value near the component exceeds the standard.

[0008] In a preferred embodiment, the fire extinguishing tank is fixedly installed on the outside of the mounting shell, a piston is slidably installed inside the fire extinguishing tank, a skin is fixedly connected to the end of the fire extinguishing tank near the electrical equipment room, dry powder is stored between the piston and the skin, a pressurization chamber is provided on the side of the piston away from the skin, and a vane pump structure is formed between the exhaust rotating body and the fire extinguishing tank.

[0009] In a preferred embodiment, the number of fire extinguishing canisters is set to multiple. A rotating ring is fixedly connected to the outside of the exhaust rotating body. A gap is formed between the mounting shell and the rotating ring. An arc-shaped protrusion is fixedly connected to the inner wall of the mounting shell at the position of the fire extinguishing canister. The arc-shaped protrusion slides and engages with the outer wall of the rotating ring. A compressed air chamber is formed between two adjacent arc-shaped protrusions. An elastic blade is slidably installed in the rotating ring, and an elastic element is provided between the elastic blade and the rotating ring. The elastic element pushes the end of the elastic blade to fit against the inner wall of the compressed air chamber. A gas filling channel is provided between the pressurization chamber and the mounting shell. The gas filling channel is connected to one side of the arc-shaped protrusion corresponding to the fire extinguishing canister. An air inlet is provided at the end of the same compressed air chamber away from the gas filling channel. The air inlet is connected to the outside of the power equipment room. The exhaust rotating body rotates along the air inlet in the same compressed air chamber towards the gas filling channel.

[0010] In a preferred embodiment, a mobile controller is installed in the mounting housing, and an exhaust channel is provided between the pressurization chamber and the inner cavity of the mounting housing. That is, during normal operation, although the vane pump structure between the exhaust rotating body and the fire extinguisher continuously pressurizes the pressurization chamber, a portion of the airflow can flow out through the exhaust channel, so that the pressurization chamber can maintain a certain high pressure. However, this high pressure value is still a certain distance from the rupture pressure value of the skin to avoid accidental rupture of the skin. A sealing ring is slidably installed in the inner wall of the mounting housing, and the sealing ring is fixedly connected to the movable end of the mobile controller.

[0011] In a preferred embodiment, a pressure relief channel is also provided between the fire extinguishing canister and the mounting shell. When the fire extinguishing canister is not triggered, the piston is positioned on the pressure relief channel to block the pressure relief channel. When the fire extinguishing canister is triggered and the skin ruptures, the gas input by the vane pump can be depressurized through the pressure relief channel.

[0012] In a preferred embodiment, a controllable sealing door is provided on the ventilation port, and a one-way valve structure is provided in the exhaust hole. A control trigger structure is provided between the positioning protection device and the controllable sealing door. After the positioning protection device detects an unexpected situation of the component, it controls the controllable sealing door to block the ventilation port through the control trigger structure, and increases the power of the exhaust rotating body to accelerate exhaust, thereby reducing the air content inside the power equipment room. The one-way valve structure in the exhaust hole allows gas to flow from inside the power equipment room through the exhaust hole into the mounting shell and then through the heat dissipation exhaust window to the outside of the heat dissipation exhaust window. However, when the airflow reverses, the one-way valve structure closes the exhaust hole, thereby maintaining a low-pressure state inside the power equipment room and preventing large-scale combustion of the equipment.

[0013] In a preferred embodiment, the one-way valve structure includes a flexible flap. One end of the flexible flap, near the inner cavity of the power equipment chamber, is fixedly connected to an exhaust port. The other end of the flexible flap is elastically bent. A check block is also fixedly connected to the exhaust port to limit the bent end of the flexible flap. A metal mesh plate is provided on the outer side of the mounting housing corresponding to the exhaust port. This metal mesh plate can isolate flames and provide some protection for the positioning protection device, while not affecting airflow. A guide rod is fixedly connected to the metal mesh plate, extending into the interior of the mounting housing and slidably connected to it. A pressure plate that cooperates with the guide rod is fixedly connected to the movable end of the motion controller. The metal mesh plate corresponds to the exhaust port. An extrusion plate is fixedly connected at the position. In its natural state, the metal mesh plate, with the help of elastic components such as springs, is pressed against the mounting shell, causing the extrusion plate to be inserted into the exhaust hole and straighten the flexible flap. At this time, the exhaust hole can always be kept open for continuous heat dissipation and exhaust. When the component malfunctions, according to the control of the sealing ring mentioned above, the moving controller synchronously drives the pressure plate to push the guide rod, causing the metal mesh plate to be subjected to external force, i.e., the extrusion plate to leave the exhaust hole. At this time, the exhaust is increased, so the airflow can pass through the exhaust hole smoothly. When the air pressure in the power equipment room drops to the limit value, the flexible flap automatically bends and, under the restriction of the backstop block, stably seals the exhaust hole, maintaining the overall low pressure effect of the power equipment room.

[0014] In a preferred embodiment, the controllable sealing door is a sealing plate, the ventilation port is located below the positioning protection device, the sealing plate is slidably installed above the ventilation port, a pull rope is fixedly connected to the top of the sealing plate, the top end of the pull rope is fixedly connected to the mounting shell, the control triggering structure is a rope cutter, the rope cutter is slidably installed in the mounting shell, and push blocks that contact each other are respectively provided between the rope cutter and the movable end of the motion controller. Thus, when the component malfunctions and the positioning protection device identifies and provides feedback, the motion controller can push the rope cutter to cut the pull rope, and the sealing plate can then slide down to block the ventilation port.

[0015] A method for locating power equipment in a power network scenario includes the following steps:

[0016] Step 1: In the power monitoring system, perform a 3D model of each power equipment room and the actual location of each component inside the power equipment room;

[0017] Step 2: Install a positioning protection device in the power equipment room, and install a signal transmitter on each component. Use the signal receiver on the positioning protection device to receive and identify the signals emitted by the signal transmitters on each component.

[0018] Step 3: By connecting the signals between the components through the positioning protection device, all components are treated as a whole. The GPS module in the positioning protection device is used for overall positioning. When the location information of the equipment needs to be retrieved, the three-dimensional model of the power equipment room is retrieved simultaneously.

[0019] Step 4: Monitor the ambient temperature of the components through the temperature sensing module in the signal transmitter, and shut down the signal transmission of the signal transmitter when the temperature exceeds the limit and an accident occurs. Use the processor in the positioning protection device to identify the accident and take protective action through the safety protection module.

[0020] Step 5: The communication module in the positioning protection device transmits the fault status information to the power monitoring system. Maintenance personnel use the GPS module in the positioning protection device to quickly locate the fault and obtain a 3D model of the power equipment room during the search process. They then locate the specific location of the faulty component so that maintenance personnel can quickly find the faulty component.

[0021] The technical effects and advantages of this invention are as follows:

[0022] 1. This invention enables the positioning protection device and all components to form a positioning whole through signal identification between the signal receiver and the signal transmitter. It uses a GPS module to locate the entire device and further locates each component by establishing a three-dimensional model, which is beneficial for staff to quickly find the device and components.

[0023] 2. This invention uses a temperature sensing module in a signal transmitter to locate and monitor components. When a component malfunctions and its temperature becomes too high, the signal transmitter stops transmitting signals. When the signal receiver cannot receive the corresponding signal from the component, the processor processes the signal and reports the fault status to the power monitoring system through the network connection of the communication module. The GPS module is used for real-time positioning, which helps maintenance personnel to quickly locate the equipment and find the faulty component.

[0024] 3. This invention controls the rapid pressurization of the pressure chamber and causes the skin to rupture when components malfunction, releasing dry powder for fire extinguishing. Simultaneously, it controls the sealing plate to block the ventilation port, increases the power of the exhaust rotating body, accelerates exhaust, and reduces the air content inside the electrical equipment room. Thus, under the extrusion of the sprayed dry powder fire extinguishing, it prevents large-scale combustion of the equipment and avoids affecting more equipment, protecting as many components and other equipment as possible from being burned, greatly improving the safety of the equipment.

Detailed Implementation

[0036] 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. Example 1

[0037] Refer to the instruction manual appendix Figure 1 To be continued Figure 3A power equipment positioning device based on a power network scenario includes a power equipment room 1. All components 11 installed in the power equipment room 1 are located on the same plane. A positioning protection device 2 is installed on one side of the power equipment room 1 opposite to the aforementioned plane. The positioning protection device 2 is equipped with a signal receiver 3 and a safety protection module 5. Each component 11 is equipped with a signal transmitter 4 for identifying itself. The signal emitted by the signal transmitter 4 is continuously received and identified by the signal receiver 3. The positioning protection device 2 includes a mounting housing 21, in which a processor 211, a GPS module 212, and a communication module 213 are installed. Block 212 is used to locate the entire equipment and communicates with the external network via communication module 213 to establish a power network scenario and interface with the power monitoring system to obtain the location and status of the equipment in real time. In the power monitoring system, the actual location of each power equipment room 1 and its internal components 11 in the power equipment room 1 is modeled and marked in three dimensions in the power network scenario. With the help of signal recognition from each signal transmitter 4, when a component 11 malfunctions, maintenance personnel can accurately locate the equipment in advance using GPS module 212 before arriving at the scene, and after identifying the malfunctioning component 11, display the immediate status. The system models the physical components and pinpoints the exact location of component 11, enabling maintenance personnel to quickly locate it. The processor 211 identifies and processes the signal between the signal receiver 3 and the signal transmitter 4. The signal transmitter 4 is equipped with a temperature sensing module; when an electrical malfunction causes excessively high temperatures, the signal is detected by the signal receiver 3 and processed by the processor 211. The fault status is then reported to the power monitoring system via the network connection of the communication module 213, and real-time location is achieved using the GPS module 212. Simultaneously, timely safety protection feedback is provided using the safety protection module 5, which includes a fire extinguisher 51 and a heat sink. The actuator 52 stores dry powder in the fire extinguishing tank 51 and sprays the dry powder to extinguish the fire when an internal fire occurs in the power equipment room 1. The heat dissipation actuator 52 is fixedly installed in the mounting shell 21, and the mounting shell 21 is located at the heat dissipation and exhaust window 13 of the power equipment room 1. The power equipment room 1 is also provided with an air exchange port 12. The heat dissipation actuator 52 is provided with an exhaust rotating body 521. The heat dissipation actuator 52 is a motor structure, and the exhaust rotating body 521 is an exhaust blade structure. The mounting shell 21 is provided with an exhaust hole 22, so that the interior of the power equipment room 1 can be vented and cooled in real time, reducing the failure rate of electrical equipment and improving the protection effect of electrical equipment.

[0038] The signal transmitter 4 is an infrared signal transmitting module, and the signal receiver 3 is an infrared signal receiving module. The temperature sensing module on the signal transmitter 4 includes a temperature control switch. When the temperature value near component 11 exceeds the standard, the temperature control switch shuts off the signal transmitter 4. At this time, the signal receiver 3 cannot receive the signal emitted by the signal transmitter 4 on component 11, and thus identifies the component 11 as faulty. The fault can be located and reported, and the safety protection module 5 is activated simultaneously for protection feedback. Based on the above principle, if component 11 is dropped or stolen, causing the signal transmitter 4 on component 11 to lose connection with the signal receiver 3, an alarm can also be triggered.

[0039] like Figure 4 As shown, the fire extinguishing tank 51 is fixedly installed on the outside of the mounting shell 21. A piston 511 is slidably installed inside the fire extinguishing tank 51. A skin 512 is fixedly connected to one end of the fire extinguishing tank 51 near the electrical equipment room 1. Dry powder is stored between the piston 511 and the skin 512. A pressure chamber 513 is provided on the side of the piston 511 away from the skin 512. A vane pump structure is formed between the exhaust rotating body 521 and the fire extinguishing tank 51. The vane pump structure pressurizes the pressure chamber 513 to cause the skin 512 to burst and spray dry powder for fire extinguishing.

[0040] like Figure 5 As shown, multiple fire extinguishing canisters 51 are provided. A rotating ring 522 is fixedly connected to the outside of the exhaust rotating body 521. A gap is formed between the mounting shell 21 and the rotating ring 522. An arc-shaped protrusion is fixedly connected to the inner wall of the mounting shell 21 at the position of the fire extinguishing canister 51. The arc-shaped protrusion slides with the outer wall of the rotating ring 522. A compressed air chamber 26 is formed between two adjacent arc-shaped protrusions. An elastic blade 523 is slidably installed in the rotating ring 522, and an elastic element is provided between the elastic blade 523 and the rotating ring 522. The elastic element pushes the end of the elastic blade 523 to adhere to the inner wall of the compressed air chamber 26. A gas filling channel 514 is provided between the pressurization chamber 513 and the mounting shell 21. The gas filling channel 514 is connected to one side of the arc-shaped protrusion corresponding to the fire extinguisher 51. An air inlet 261 is provided at the end of the same compression chamber 26 away from the gas filling channel 514. The air inlet 261 is connected to the outside of the power equipment room 1. The exhaust rotating body 521 rotates along the air inlet 261 in the same compression chamber 26 toward the gas filling channel 514, thereby forming a complete vane pump structure. The rotation of the exhaust rotating body 521 can be used to make the elastic vanes 523 pressurize the pressurization chamber 513.

[0041] To ensure stable air pressure in the pressurization chamber 513 when the skin 512 is detonated when not needed, this embodiment provides the following technical solution: (e.g.) Figure 4As shown, a mobile controller 24 is installed in the mounting housing 21. An exhaust channel 515 is provided between the pressurization chamber 513 and the inner cavity of the mounting housing 21. That is, during normal operation, although the vane pump structure between the exhaust rotating body 521 and the fire extinguishing tank 51 continuously pressurizes the pressurization chamber 513, a portion of the airflow can flow out through the exhaust channel 515, so that the pressurization chamber 513 can maintain a certain high pressure. However, this high pressure value is still a certain gap from the rupture pressure value of the skin 512, so as to avoid the accidental rupture of the skin 512. A sealing ring 241 is slidably installed in the inner wall of the mounting housing 21. The sealing ring 241 is fixedly connected to the movable end of the mobile controller 24. The mobile controller 24 can be a linear motor. When the component 11 malfunctions, after triggering the system, the mobile controller 24 controls the sealing ring 241 to seal the exhaust channel 515, which can quickly increase the pressure in the pressurization chamber 513 and cause the skin 512 to rupture, releasing dry powder for fire extinguishing.

[0042] Based on the above technical solution, in order to ensure that the fire extinguishing canister 51 will not continue to be pressurized after the dry powder is added, a pressure relief channel 516 is also provided between the fire extinguishing canister 51 and the mounting shell 21. When the fire extinguishing canister 51 is not triggered, the piston 511 is located on the pressure relief channel 516 to block the pressure relief channel 516. When the fire extinguishing canister 51 is triggered and the skin 512 is ruptured, the gas input by the vane pump can be depressurized through the pressure relief channel 516.

[0043] In the above technical solutions, such as Figure 1 As shown, the ventilation port 12 is equipped with a controllable sealing door 6, such as Figure 2 and Figure 3 As shown, a one-way valve structure 23 is provided in the exhaust port 22. A control trigger structure is provided between the positioning protection device 2 and the controllable sealing door 6. After the positioning protection device 2 detects an unexpected situation of the component 11, it controls the controllable sealing door 6 to block the ventilation port 12 through the control trigger structure, and increases the power of the exhaust rotating body 521 to accelerate the exhaust, reduce the air content inside the power equipment room 1. The one-way valve structure 23 in the exhaust port 22 allows gas to flow from inside the power equipment room 1 through the exhaust port 22 to the mounting shell 21 and then through the heat dissipation exhaust window 13 to the outside of the heat dissipation exhaust window 13. However, when the airflow flows in the opposite direction, the one-way valve structure 23 closes the exhaust port 22, thereby maintaining a low-pressure state inside the power equipment room 1 and reducing the air content. Thus, under the extrusion of dry powder fire extinguishing, large-scale combustion of equipment is avoided, which would affect more equipment. This protects as many components 11 and other equipment as possible from being burned, greatly improving the safety of the equipment.

[0044] like Figure 6As shown, the one-way valve structure 23 includes a flexible flap 231. One end of the flexible flap 231, near the inner cavity of the power equipment chamber 1, is fixedly connected to the exhaust port 22. The other end of the flexible flap 231 is elastically bent. A check block 232, which limits the bent end of the flexible flap 231, is also fixedly connected in the exhaust port 22. Figure 4 As shown, a metal mesh plate 27 is provided on the side of the mounting housing 21 corresponding to the exhaust port 22. This metal mesh plate 27 can isolate the flame and provide a certain degree of protection for the positioning protection device 2, while not affecting the airflow. A guide rod 271 is fixedly connected to the metal mesh plate 27. The guide rod 271 extends into the interior of the mounting housing 21 and is slidably connected to the mounting housing 21. A pressure plate 242 that cooperates with the guide rod 271 is fixedly connected to the movable end of the movement controller 24. The metal mesh plate 27 is fixed at the position corresponding to the exhaust port 22. The metal mesh plate 27, connected to the extrusion plate 272, is in its natural state held in close contact with the mounting shell 21 by an elastic element, such as a spring, so that the extrusion plate 272 is inserted into the vent hole 22 and the flexible flap 231 is straightened. At this time, the vent hole 22 remains unobstructed for continuous heat dissipation and exhaust. However, if component 11 malfunctions, according to the control of the sealing ring 241 described above, the movement controller 24 synchronously drives the pressure plate 242 to push the guide rod 271, causing external force on the metal mesh plate 27, i.e., the extrusion plate 272, to leave the vent hole 22. Figure 7 As shown, this is the period of increased exhaust, so the airflow can pass smoothly through exhaust port 22. However, when the air pressure in the power equipment room 1 drops to its limit, as... Figure 8 As shown, the flexible flap 231 automatically bends and, under the restriction of the backstop block 232, stably seals the exhaust port 22, maintaining the overall low-pressure effect of the power equipment room 1.

[0045] like Figure 2 and Figure 3 As shown, the controllable sealing door 6 is a sealing plate 61, and the ventilation port 12 is located below the positioning protection device 2. The sealing plate 61 is slidably installed above the ventilation port 12. A pull rope 62 is fixedly connected to the top of the sealing plate 61, and the top end of the pull rope 62 is fixedly connected to the mounting shell 21. The control triggering structure is a rope cutter 25, which is slidably installed in the mounting shell 21. Push blocks 243 that contact each other are respectively provided between the rope cutter 25 and the movable end of the motion controller 24. Thus, when the component 11 is abnormal and the positioning protection device 2 identifies and provides feedback, the motion controller 24 can push the rope cutter 25 to cut the pull rope 62, and the sealing plate 61 can then slide down to block the ventilation port 12.

[0046] A method for locating power equipment in a power network scenario includes the following steps:

[0047] Step 1: In the power monitoring system, perform a three-dimensional model of the actual positions of each power equipment room 1 and its internal components 11 within the power equipment room 1.

[0048] Step 2: Install the positioning protection device 2 in the power equipment room 1, and install the signal transmitter 4 on each component 11. Use the signal receiver 3 on the positioning protection device 2 to receive and identify the signals emitted by the signal transmitter 4 on each component 11.

[0049] Step 3: By connecting the signals between each component 11 through the positioning protection device 2, all components 11 are treated as a whole. The GPS module 212 in the positioning protection device 2 is used for overall positioning. When the location information of the equipment needs to be retrieved, the three-dimensional model of the power equipment room 1 is retrieved simultaneously.

[0050] Step 4: Monitor the ambient temperature of component 11 through the temperature sensing module in signal transmitter 4, and shut down the signal transmission of signal transmitter 4 when the temperature exceeds the limit and an accident occurs. Use processor 211 in positioning protection device 2 to identify the accident and take protective action through safety protection module 5.

[0051] Step 5: The communication module 213 in the positioning protection device 2 transmits the fault status information to the power monitoring system. The maintenance personnel use the GPS module 212 in the positioning protection device 2 to quickly locate the faulty component 11. During the search, the personnel obtain a three-dimensional model of the power equipment room 1 and locate the specific location of the faulty component 11 so that the maintenance personnel can quickly find the faulty component 11.

[0052] In this embodiment, the specific implementation scenario is as follows: through signal identification between the signal receiver 3 and the signal transmitter 4, the positioning protection device 2 and all components 11 form a positioning whole. The GPS module 212 is used for overall device positioning, and each component 11 is further positioned by establishing a three-dimensional model. Simultaneously, the signal transmitter 4 monitors the positioning of the components 11. When a component 11 malfunctions and causes excessively high temperatures, the signal transmitter 4 stops transmitting signals. When the signal receiver 3 cannot receive the corresponding signal from that component 11, the processor 2... After the fault is processed, the fault status is reported to the power monitoring system via the network connection of the communication module 213, and the GPS module 212 is used for real-time positioning, which helps maintenance personnel to quickly locate the equipment and find the faulty component 11. At the same time, the equipment is cooled by installing the exhaust rotating body 521 and the rotating ring 522 in the mounting housing 21, which improves the safety of the equipment. The rotation of the exhaust rotating body 521 causes the elastic blades 523 to pressurize the pressurization chamber 513. During normal operation, part of the airflow can flow out through the exhaust channel 515, so that the pressurization chamber 513 can maintain a certain pressure. The pressure is set at a constant high, but this high pressure value is still somewhat different from the rupture pressure value of the skin 512 to avoid accidental rupture of the skin 512. When component 11 malfunctions, after the system is triggered, the mobile controller 24 controls the sealing ring 241 to seal the exhaust passage 515, the pressure chamber 513 is rapidly pressurized, and the skin 512 ruptures, allowing dry powder to be released for fire extinguishing. At the same time, the mobile controller 24 pushes the rope cutter 25 to cut the pull rope 62, causing the sealing plate 61 to block the ventilation port 12. At this time, the power of the exhaust rotating body 521 is increased to accelerate exhaust and reduce the air pressure inside the power equipment room 1. The air content is reduced, and the one-way valve structure 23 in the exhaust port 22 allows the gas to flow from inside the power equipment chamber 1 through the exhaust port 22 into the mounting shell 21 and then through the heat dissipation exhaust window 13 to the outside. However, when the airflow reverses, the one-way valve structure 23 closes the exhaust port 22, thereby maintaining a low pressure state inside the power equipment chamber 1 and reducing the air content. This prevents large-scale combustion of the equipment from affecting more equipment under the pressure of dry powder fire extinguishing spray, and protects as many components 11 and other equipment as possible from being burned, greatly improving the safety of the equipment. Example 2

[0053] Based on Embodiment 1, a power equipment positioning device for a power network scenario differs in that the signal receiver 3 and signal transmitter 4 are replaced with a visual monitoring and thermal imaging monitoring system. Thermal imaging technology is used to identify the temperature near each component 11 in real time. When a fault occurs and the temperature rises, the device performs functions such as fault information identification, safety protection feedback, and fault reporting. At the same time, an alarm 214 can be added to the positioning protection device 2 to alarm the equipment. This embodiment has a higher implementation cost, therefore, it is more suitable for high-value and extremely important power equipment.

[0054] In conclusion, 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, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
