Description

Technical Field

[0001] This invention relates to the field of power fire prevention and control technology, specifically to a multi-level linkage power fire prevention and control device. Background Technology

[0002] With the continuous expansion of the power system and the continuous increase in the power density of electrical equipment, power facilities such as distribution cabinets, transformer equipment, and battery energy storage units are prone to local high temperatures, abnormal currents, and smoke accumulation during long-term operation due to overload operation, poor contact, insulation aging, or environmental factors. If these phenomena are not detected and dealt with in time, they can easily induce power fire accidents, posing a serious threat to personnel safety, stable operation of the power system, and property safety.

[0003] In practice, some problems still exist:

[0004] Existing power fire prevention and control devices mostly adopt single-point temperature detection or simple current monitoring methods. The monitoring dimensions are single and the detection range is limited. They often only issue alarms after the fire hazard has obviously formed. They lack the ability to comprehensively judge the early signs of fire. Moreover, there is no effective information linkage mechanism between different monitoring units, making it difficult to achieve a graded response from local anomalies to overall prevention and control. This easily leads to false alarms, missed alarms, or delayed responses, reducing the actual effectiveness of power fire prevention and control.

[0005] Furthermore, existing power fire prevention and control devices generally neglect the stability of their own operating environment in their structural design. During long-term operation, heat can easily accumulate inside the device due to the heating of electronic components. If the heat dissipation path is unreasonable or the heat dissipation efficiency is insufficient, it can easily accelerate the aging of components and even cause secondary safety hazards. At the same time, in humid or temperature-varying environments, water vapor can easily condense inside the device, leading to line corrosion and reduced insulation performance, further increasing the risk of power fires. In existing technologies, heat dissipation and dehumidification are mostly passive or independently set up, lacking a linkage design that is integrated with the overall prevention and control logic. Summary of the Invention

[0006] Therefore, the present invention provides a multi-level linkage power fire prevention and control device to solve the problems of single monitoring, insufficient linkage, and uncoordinated heat dissipation and dehumidification in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A multi-level linkage power fire prevention and control device includes a power fire prevention and control device body, a heat dissipation mechanism on the back of the power fire prevention and control device body, a dehumidification mechanism inside the power fire prevention and control device body, a distributed sensor connected to the top of the power fire prevention and control device body, and a communication module inside the power fire prevention and control device body.

[0009] The distributed sensors are used to collect operating parameters at different locations of the monitored power equipment and output monitoring signals to the communication module. The communication module is used to send the monitoring signals to the external control terminal and receive control signals fed back from the external control terminal.

[0010] The electrical fire prevention and control device is equipped with a linkage execution interface electrically connected to the communication module. The linkage execution interface is used to perform corresponding linkage control operations on the monitored electrical equipment after receiving the control signal.

[0011] The heat dissipation mechanism includes a heat-conducting plate, a heat-dissipating copper pipe, a circulation pipeline, a mounting frame, and a cooling fan. The heat-conducting plate is fixedly embedded on the back of the main body of the power fire prevention and control device. A heat-dissipating copper pipe is fixedly connected to the outside of the heat-conducting plate. The heat-dissipating copper pipe is sleeved on the outside of the circulation pipeline. A mounting frame is provided on the back of the circulation pipeline. A cooling fan is connected to the inside of the mounting frame.

[0012] The dehumidification mechanism includes a dehumidification box, desiccant granules, a connecting plate, a stirring rod, and a transmission component. The dehumidification box is fixedly connected to the inner wall of the main body of the power fire prevention and control device. The desiccant granules are laid inside the dehumidification box. A connecting plate is slidably connected to the middle of the dehumidification box. A fixing plate is fixedly connected to one end of the connecting plate. A stirring rod is fixedly connected to the bottom end of the fixing plate. A transmission component is fixedly connected to the other end of the connecting plate.

[0013] Furthermore: the distributed sensor is electrically connected to the communication module, the circulation pipeline is fixedly connected to the back of the power fire prevention and control device body, and the heat-conducting plate is placed inside the battery fire prevention and control device body.

[0014] Furthermore: the central shaft of the cooling fan is fixedly connected to a drive shaft, and one end of the drive shaft is fixedly connected to a drive plate.

[0015] Furthermore: a reset spring rod is fixedly connected to the inner side of the transmission plate, and a cleaning wiper is fixedly connected to the free end of the reset spring rod, with the inner side of the cleaning wiper attached to the outer side of the mounting frame.

[0016] Furthermore: the bottom end of the cleaning wiper is slidably connected to the outside of the drive shaft.

[0017] Furthermore: both ends of the circulation pipeline are fixedly connected to water connection pipes, and the back of the circulation pipeline is fixedly connected to a connector, which is fixedly connected to the mounting frame.

[0018] Furthermore, a pressing block is fixedly connected to the inner side of the transmission plate, and one side of the pressing block is placed on the outer side of the transmission member.

[0019] Furthermore: a support plate is fixedly connected to the top of the connecting plate, and a pull-back spring rod is fixedly connected to the back of the main body of the power fire prevention and control device.

[0020] Furthermore: the free end of the pull-back spring rod is fixedly connected to the inner side of the support plate, and the support plate is slidably connected to the top of the main body of the power fire prevention and control device.

[0021] Furthermore, a protective net is fixedly embedded on the outer side and bottom of the dehumidification box, and a sealing cap is fixedly connected to the top of the dehumidification box.

[0022] The present invention has the following advantages:

[0023] 1. This invention involves installing distributed sensors at the top of the power fire prevention and control device and electrically connecting them to the internal communication module. These distributed sensors collect operating parameters from different locations of the monitored power equipment in a decentralized manner and transmit the collected monitoring signals to the communication module. The communication module then sends the monitoring signals to an external control terminal and receives the control signals fed back from it. Upon receiving the control signals, the linkage execution interface within the device executes corresponding linkage control operations on the monitored power equipment. This establishes a hierarchical linkage relationship between the device, the external control terminal, and the monitored power equipment, avoiding response delays caused by single detection or unidirectional transmission and improving the collaborative control effect in the power fire prevention and control process.

[0024] 2. This invention provides a heat dissipation mechanism on the back of the power fire prevention device, consisting of a heat-conducting plate, heat dissipation copper pipes, circulation pipes, mounting frame, and cooling fan forming a multi-stage heat dissipation path. This allows the heat generated inside the device to be quickly dissipated and continuously dispersed, preventing damage to internal electronic components from localized high temperatures. Simultaneously, during operation, the cooling fan drives a transmission plate via a drive shaft. A reset spring rod and a cleaning wiper on the inner side of the transmission plate provide automatic cleaning without additional drive, continuously cleaning dust from the outside of the mounting frame and the heat dissipation area. This prevents dust accumulation from affecting heat dissipation efficiency, thereby extending the service life of the cooling fan and circulation pipes, improving the long-term stability and reliability of the heat dissipation mechanism, and reducing the frequency of manual maintenance.

[0025] 3. This invention incorporates a dehumidification mechanism within the main body of the power fire prevention and control device. Through the coordinated operation of the dehumidification box, desiccant granules, connecting plate, stirring rod, and transmission components, the internal humidity of the device can be continuously regulated during operation. When the transmission plate drives the extrusion block to contact the transmission components, the connecting plate reciprocates and slides, driving the stirring rod to agitate the desiccant granules, ensuring the desiccant remains in a uniform moisture-absorbing state. This prevents localized clumping or moisture saturation, which could lead to a decrease in dehumidification efficiency. Simultaneously, the support plate and the return spring rod work together to achieve automatic reset, allowing the dehumidification mechanism to operate periodically without additional control. This effectively reduces the risk of short circuits, corrosion, and decreased insulation performance caused by moisture within the main body of the power fire prevention and control device, further enhancing the safety and stability of the overall operating environment of the device.

Technical engineers in the field can make some non-essential improvements and adjustments to the present invention based on the above-described content. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are part of the present invention.

[0038] The main body 1 of the power fire prevention and control device is equipped with a linkage execution interface that is electrically connected to the communication module 5. The linkage execution interface is used to perform corresponding linkage control operations on the monitored power equipment after receiving a control signal.

[0039] The heat dissipation mechanism 2 includes a heat-conducting plate 203, a heat dissipation copper pipe 204, a circulation pipe 205, a mounting frame 202, and a cooling fan 207. The heat-conducting plate 203 is fixedly embedded on the back of the main body 1 of the power fire prevention and control device. The heat dissipation copper pipe 204 is fixedly connected to the outside of the heat-conducting plate 203. The heat dissipation copper pipe 204 is sleeved on the outside of the circulation pipe 205. The back of the circulation pipe 205 is provided with a mounting frame 202. The inner side of the mounting frame 202 is connected to the cooling fan 207.

[0040] The dehumidification mechanism 3 includes a dehumidification box 301, desiccant granules 307, a connecting plate 304, a stirring rod 306, and a transmission component 309. The dehumidification box 301 is fixedly connected to the inner wall of the main body 1 of the power fire prevention and control device. The desiccant granules 307 are laid inside the dehumidification box 301. The connecting plate 304 is slidably connected to the middle of the dehumidification box 301. A fixing plate 305 is fixedly connected to one end of the connecting plate 304. A stirring rod 306 is fixedly connected to the bottom end of the fixing plate 305. The transmission component 309 is fixedly connected to the other end of the connecting plate 304.

[0041] In the aforementioned components, the device uses the main body 1 of the power fire prevention and control device as the supporting foundation during operation. The distributed sensors 4 connected to the top collect the operating status of different locations in real time and transmit the collected temperature, current and smoke-related signals to the communication module 5. The communication module 5 summarizes the information and uses it to control the heat dissipation mechanism 2 and the dehumidification mechanism 3 to operate synchronously. The heat dissipation mechanism 2 is used to reduce the internal temperature rise of the device body, and the dehumidification mechanism 3 is used to improve the internal humidity environment. In this way, key factors can be actively controlled before fire hazards are formed, thereby improving the overall reliability of prevention and control.

[0042] The distributed sensor 4 is electrically connected to the communication module 5, the circulation pipeline 205 is fixedly connected to the back of the main body 1 of the power fire prevention and control device, and the heat conduction plate 203 is placed inside the main body of the battery fire prevention and control device.

[0043] In the above components, the distributed sensor 4 continuously collects the status parameters of each area of ​​the power fire prevention and control device body 1 during the operation of the device, and transmits the data to the communication module 5 in real time through electrical connection. The circulation pipeline 205 is fixed to the back of the device to form a stable heat dissipation circuit. The heat conduction plate 203 is set inside the battery fire prevention and control device body to directly absorb internal heat and conduct it outward, thereby forming a collaborative working relationship between information monitoring and heat regulation to ensure the stability of the device's operating environment.

[0044] The central shaft of the cooling fan 207 is fixedly connected to a drive shaft 209, and one end of the drive shaft 209 is fixedly connected to a drive plate 208.

[0045] In the aforementioned components, when the cooling fan 207 is started, its central shaft drives the transmission shaft 209 to rotate synchronously. The transmission shaft 209 transmits the rotational power to the transmission plate 208 fixedly connected at one end, causing the transmission plate 208 to generate a linkage action during the operation of the cooling fan 207. This structure achieves mechanical transmission without adding an additional power source, providing a stable driving foundation for the subsequent cleaning and dehumidification linkage structure, thereby improving the overall mechanism coordination.

[0046] A reset spring rod 211 is fixedly connected to the inner side of the transmission plate 208, and a cleaning wipe plate 210 is fixedly connected to the free end of the reset spring rod 211. The inner side of the cleaning wipe plate 210 is attached to the outer side of the mounting frame 202.

[0047] In the aforementioned components, the transmission plate 208 drives the return spring rod 211 fixedly connected to its inner side to undergo periodic deformation during rotation. The free end of the return spring rod 211 pushes the cleaning wipe plate 210 to move along the outer side of the mounting frame 202, so that the cleaning wipe plate 210 always adheres to the surface of the mounting frame 202 to wipe away the dust attached to the heat dissipation area, avoiding dust accumulation that affects the heat dissipation effect. At the same time, the return spring rod 211 can automatically reset after the external force disappears.

[0048] The bottom end of the cleaning wiper 210 is slidably connected to the outside of the drive shaft 209.

[0049] In the above components, the bottom end of the cleaning wipe plate 210 is slidably connected to the outside of the transmission shaft 209, so that the cleaning wipe plate 210 remains under stable force when it moves with the transmission plate 208. The offset stress is absorbed by sliding, avoiding rigid interference between the cleaning wipe plate 210 and the mounting frame 202. This reduces the wear of the mechanism while ensuring the cleaning effect, and improves the reliability and durability of the heat dissipation mechanism 2 in long-term operation.

[0050] Both ends of the circulation pipe 205 are fixedly connected to water connection pipes 201, and the back of the circulation pipe 205 is fixedly connected to a connector 206, which is fixedly connected to the mounting frame 202.

[0051] In the above components, the water connection pipes 201 at both ends of the circulation pipe 205 are used to connect with the external cooling medium, so that the medium inside the circulation pipe 205 can flow continuously and carry away heat. The back of the circulation pipe 205 is fixedly connected to the mounting frame 202 through the connector 206, thereby ensuring that the pipe maintains a stable position during long-term operation and avoiding a decrease in heat dissipation efficiency due to vibration or thermal expansion and contraction.

[0052] An extrusion block 308 is fixedly connected to the inner side of the transmission plate 208, and one side of the extrusion block 308 is placed on the outer side of the transmission member 309.

[0053] In the above components, the pressing block 308 fixedly connected to the inner side of the transmission plate 208 moves synchronously during rotation. When the pressing block 308 moves to the contact position with the transmission member 309, it generates a thrust on the transmission member 309, causing the transmission member 309 to drive the connecting plate 304 to move. This structure uses the mechanical energy generated by the operation of the cooling fan 207 to realize the linkage drive of the dehumidification mechanism 3, avoiding the increase in energy consumption caused by setting up a separate power structure.

[0054] A support plate 310 is fixedly connected to the top of the connecting plate 304, and a pull-back spring rod 311 is fixedly connected to the back of the main body 1 of the power fire prevention and control device.

[0055] In the aforementioned components, when the connecting plate 304 reciprocates under the drive of the transmission component 309, the support plate 310 fixedly connected to its top moves synchronously. The pull-back spring rod 311 provided on the back of the main body 1 of the power fire prevention and control device is stretched and stores energy during the movement of the support plate 310. When the external force is released, the pull-back spring rod 311 releases its elastic potential energy to push the support plate 310 to reset, thereby realizing the automatic return of the connecting plate 304 and the dehumidification mechanism 3.

[0056] The free end of the pull-back spring rod 311 is fixedly connected to the inner side of the support plate 310, and the support plate 310 is slidably connected to the top of the main body 1 of the power fire prevention and control device.

[0057] In the above components, the free end of the pull-back spring rod 311 is fixedly connected to the inner side of the support plate 310, so that the support plate 310 is always constrained by the pull-back force during the movement. The support plate 310 is slidably connected to the top of the main body 1 of the power fire prevention and control device. The sliding fit ensures the stability of the movement direction of the support plate 310 and avoids the connection plate 304 from shifting, thereby improving the stability and repeatability of the operation of the dehumidification mechanism 3.

[0058] A protective net 302 is fixedly embedded on the outside and bottom of the dehumidification box 301, and a sealing cover 303 is fixedly connected to the top of the dehumidification box 301.

[0059] In the above components, the protective net 302 fixedly embedded on the outside and bottom of the dehumidification box 301 is used to prevent the desiccant particles 307 from leaking out during the stirring process, while ensuring that air can smoothly enter the interior of the dehumidification box 301. The sealing cover 303 set at the top of the dehumidification box 301 is used to limit the backflow of moisture and improve the dehumidification efficiency, so that the dehumidification mechanism 3 maintains good sealing and safety during long-term operation, thereby stabilizing and improving the internal environment of the device.

[0060] Working principle: In actual operation, the main body 1 of the power fire prevention and control device serves as the overall prevention and control carrier. The distributed sensors 4 arranged at its top continuously monitor the key nodes in the operation of the power equipment. The distributed sensors 4 collect data on temperature changes, smoke concentration, and abnormal current status in real time, and the collected data signals are collected and transmitted through the communication module 5. When any distributed sensor 4 detects abnormal parameter fluctuations, the communication module 5 immediately sends the corresponding abnormal information to the regional control center. The regional control center performs comprehensive analysis and judgment based on historical operating data and the current real-time status, thereby realizing the early identification and early warning response of potential power fire hazards. After the multi-level linkage logic is triggered, the various functional mechanisms inside the main body of the device enter a collaborative working state to ensure the stability and safety of the equipment operating environment.

[0061] During continuous operation of the device, the heat dissipation mechanism 2 on the back of the main body 1 of the power fire prevention and control device plays an important role in dissipating heat from the internal electrical components. The heat conduction plate 203 is fixedly embedded on the back of the main body 1 of the power fire prevention and control device. It can quickly absorb the concentrated heat generated inside the device and conduct it to the outside. The heat dissipation copper pipe 204 fixedly connected to the outside of the heat conduction plate 203 and the circulation pipe 205 form a stable heat exchange channel. The circulation pipe 205 forms a closed circulation path with the cooperation of the water connection pipe 201, so that the heat is continuously transferred along the pipe and the local temperature rise is reduced. When the cooling fan 207 is started, its central shaft drives the transmission shaft 209 to rotate synchronously. The transmission plate 208 connected to one end of the transmission shaft 209 moves accordingly, thereby improving the air flow efficiency and the heat exchange effect around the heat dissipation copper pipe 204 and the circulation pipe 205, and avoiding the aging or failure of the internal components of the main body 1 of the power fire prevention and control device due to local high temperature.

[0062] Meanwhile, during the long-term operation of the cooling fan 207, the reset spring rod 211 fixedly connected to the inner side of the transmission plate 208 will undergo periodic deformation under the rotation drive. The cleaning wipe plate 210 connected to its free end will always be in contact with the outer side of the mounting frame 202. It will automatically clean the mounting frame 202 and the surrounding area through reciprocating sliding, thereby preventing dust accumulation from affecting the operating stability of the cooling fan 207. The bottom end of the cleaning wipe plate 210 is slidably connected to the outer side of the transmission shaft 209. While ensuring the reliability of the cleaning action, it avoids generating additional resistance to the transmission structure, further improving the long-term operating reliability of the heat dissipation mechanism 2.

[0063] In terms of moisture prevention and dehumidification, the dehumidification mechanism 3 inside the main body 1 of the power fire prevention and control device is used to improve the humidity conditions of the internal environment. The dehumidification box 301 is fixedly connected to the inner wall of the main body of the device. The desiccant particles 307 laid inside it are used to absorb moisture in the air. When the squeezing block 308 on the inner side of the transmission plate 208 moves with the transmission structure and comes into contact with the transmission component 309, the transmission component 309 drives the connecting plate 304 to slide back and forth. The fixed plate 305 connected to one end of the connecting plate 304 further drives the stirring rod 306 to rotate inside the dehumidification box 301, so that the desiccant particles 307 are in a dynamic turning state, thereby improving the dehumidification efficiency and avoiding local saturation failure of the desiccant. The support plate 310 fixedly connected to the top of the connecting plate 304 is automatically reset under the action of the pull-back spring rod 311, so that the dehumidification mechanism 3 can complete the periodic self-adjustment operation without relying on external control.

[0064] 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 within the protection scope of the present invention.
