Description

Technical Field

[0001] The present invention relates to the technical field of electric power fire protection, and particularly relates to a distributed photovoltaic power station roof fire treatment system. Background Art

[0002] Solar photovoltaic power generation has the advantages of rich resources, cleanness, and being not restricted by the geographical distribution of resources. In recent years, the photovoltaic industry has developed rapidly, and more and more photovoltaic power stations have been built. However, the fire problem of the photovoltaic power generation system may cause huge losses to people and property.

[0003] Especially for the fire problem of the distributed rooftop photovoltaic power generation system combined with buildings, compared with other fires, it has the following characteristics: (1) After the photovoltaic power station catches fire, it is still energized, and due to electrical insulation damage or live wire breakage and grounding, step voltage and touch voltage will exist within a certain range. If maintenance personnel do not pay attention when going to the roof to extinguish the fire, electric shock accidents may occur; (2) The factory building covers a large area, generally with a height greater than 7 meters, a large space, and good air circulation. Once a fire breaks out, the fire can spread in any direction, burn violently, and easily generate a strong thermal airflow to form a large-area combustion, resulting in major accidents; (3) Maintenance personnel cannot detect the roof fire in time. Since the roof photovoltaic modules are installed on the roof of an outdoor open space, the temperature and smoke sensors of the traditional fire monitoring system cannot sense the occurrence of the fire in time and accurately to give an alarm, and the maintenance personnel cannot handle the fire in time, resulting in the expansion of the fire; (4) Due to the small capacity of the rooftop distributed project, many are unmanned power stations. For some rooftop power stations with a relatively large capacity, the number of rooftops installed with photovoltaics is relatively large, and the back-end monitoring room is also at a considerable distance from some rooftops. Therefore, it also takes some time for the maintenance personnel to arrive at the scene, thus delaying the timely extinguishment of the fire.

[0004] Therefore, how to provide a distributed photovoltaic power station roof fire treatment system that can accurately sense the fire situation, effectively prevent the spread of the fire or extinguish the fire safely, and avoid electric shock to maintenance personnel is a technical problem that needs to be solved urgently by those skilled in the art.

[0033] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please refer to Figures 1 to 7 , where Figure 1 is a schematic diagram of the composition of the distributed photovoltaic power station roof fire treatment system provided by the embodiment of the present invention, Figure 2 is a control schematic diagram of the distributed photovoltaic power station roof fire treatment system provided by the embodiment of the present invention, Figure 3 is a processing logic diagram of the distributed photovoltaic power station roof fire treatment system provided by the embodiment of the present invention, Figure 4 is a floor plan of the distributed photovoltaic power station roof fire treatment system provided by the embodiment of the present invention, Figure 5 is Figure 4 the A-A sectional view of the distributed photovoltaic power station roof fire treatment system in Figure 6 is Figure 4 the B-B sectional view of the distributed photovoltaic power station roof fire treatment system in Figure 7 is Figure 5 the C-C sectional view of the distributed photovoltaic power station roof fire treatment system in

[0035] In the first specific embodiment, the distributed photovoltaic power station roof fire treatment system provided by the present invention includes: an image-type fire detector module 3, a fire alarm module 6, a fire blanket protection box module 2, a power trolley module 1, and a system controller 5. The system controller 5 is respectively connected to the image-type fire detector module 3, the fire alarm module 6, and the power trolley module 1, and the power trolley module 1 is used in cooperation with the fire blanket protection box module 2. Among them, the image-type fire detector module 3 includes an image-type fire detector 31, and the image-type fire detector 31 is used to monitor the fire situation on the photovoltaic roof 9; the fire alarm module 6 includes an audible and visual alarm 61, and the audible and visual alarm 61 is used to give an alarm when a fire occurs; the fire blanket protection box module 2 includes a fire blanket 21, and the fire blanket 21 is used to be laid on the photovoltaic roof 9 when a fire occurs; the power trolley module 1 includes a power trolley 101, and the power trolley 101 is used to pull the fire blanket 21 for laying.

[0036] The distributed photovoltaic power station roof fire handling system monitors the fire situation of the photovoltaic roof 9 through the image fire detector 31 of the image fire detector module 3. When the image fire detector module 3 detects the fire situation, the system controller 5 simultaneously controls the fire alarm module 6 and the power trolley module 1 to perform two processes of fire fighting measures, and the two processes are not in order. Among them, in the first process, the sound and light alarm 61 of the fire alarm module 6 alarms, thereby realizing the alarm notification of the distributed photovoltaic power station roof fire handling system; in the second process, the power trolley module 1 is used in conjunction with the fire blanket protection box module 2, and the power trolley 101 of the power trolley module 1 directly pulls the fire blanket 21 of the fire blanket protection box module 2, and the power trolley 101 moving on the surface of the photovoltaic roof 9 spreads the fire blanket 21, and the spread fire blanket 21 is laid on the surface of the photovoltaic roof 9, thereby realizing the coverage fire extinguishing of the distributed photovoltaic power station roof fire handling system.

[0037] The distributed photovoltaic power station roof fire handling system is particularly suitable for fire problems in photovoltaic power generation systems, especially fires in distributed rooftop photovoltaic power generation systems combined with buildings. More than 80% of fire accidents in photovoltaic power stations are caused by DC side faults, especially component hot spots and DC arcing; in rooftop power stations, because the entire power station has hundreds of components and hundreds of joints, any poor contact of any joint may cause DC arcs, and once there is an arc, it will cause a fire, which is also becoming a "pain point" in the safety of photovoltaic power stations. The distributed photovoltaic power station roof fire handling system is particularly suitable for distributed photovoltaic power station roofs. The image fire detector 31 of the image fire detector module 3 is different from the temperature and smoke sensors used in traditional fire monitoring systems. It can accurately and timely sense the fire situation of the photovoltaic roof 9, and can be further expanded to timely notify the operation and maintenance personnel in the background alarm, and the operation and maintenance personnel can view the fire situation through video; at the same time, the power trolley 101 pulls the fire blanket 21 to lay the photovoltaic roof 9. The fire extinguishing method can cover the fire source and block the air, effectively prevent the spread of fire, buy time for the operation and maintenance personnel to reach the roof, and even quickly and effectively extinguish the fire safely. The photovoltaic roof 9 has photovoltaic components 10, which can not only ignite but also have the risk of discharge. After the photovoltaic roof 9 is laid with the fire blanket 21, the sunlight is blocked, the output voltage of the photovoltaic component 10 is reduced or disappears, and the DC equipment of the photovoltaic roof 9 is not energized. There is no risk of electric shock when the operation and maintenance personnel go up to the photovoltaic roof 9 to check the situation and extinguish the fire.

[0038] In this embodiment, the power cart 101 has a cart carriage 11, and cart wheels 12 are provided at the bottom of the cart carriage 11. The power cart 101 is located on the surface of the photovoltaic roof 9 and is movable. One side of the fire extinguishing blanket 21 is fixed to the photovoltaic roof 9, and the other side can be fixed to the power cart 101, so that the power cart 101 drives the fire extinguishing blanket 21 to move and unfolds the fire extinguishing blanket 21. On this basis, fire extinguishing blankets 21 of different sizes can be set according to the area and width of the photovoltaic roof 9. When the area of the fire extinguishing blanket 21 is large, multiple groups of power carts 101 can also be set to carry out the spreading work of the fire extinguishing blanket 21 simultaneously. Among them, the power cart 101 can adopt a form with its own power such as a power source and a motor 13. The power source drives the motor 13, and the motor 13 drives the cart wheels 12 to roll. It can also adopt a form without its own power, such as having a motor 13 but no power source, which should also fall within the scope of the description of this embodiment.

[0039] In an embodiment where the power cart 101 of the power cart module 1 does not have its own power, the distributed photovoltaic power station roof fire treatment system further includes an energy storage module 7. The energy storage module 7 provides the energy to drive the power cart 101. The power cart module 1 is connected to the system controller 5 through the energy storage module 7, that is, the energy storage module 7 is respectively connected to the system controller 5 and the power cart module 1. The energy storage module 7 includes an energy storage battery 71 and a charge and discharge controller 72 connected to each other. Among them, the charge and discharge controller 72 is connected to the system controller 5, and the energy storage battery 71 is connected to the motor 13. When the system controller 5 receives the signal of the fire occurrence, the system controller 5 sends an instruction to the energy storage module 7, so that the charge and discharge controller 72 controls the energy storage battery 71 to discharge, the motor 13 gets powered and starts to drive the cart wheels 12 to roll, and the power cart 101 automatically starts to lay the fire extinguishing blanket 21.

[0040] In addition, in order to limit the movement path of the power cart 101 to provide a more accurate and stable laying of the fire extinguishing blanket 21, the distributed photovoltaic power station roof fire treatment system further includes a traveling guide rail module 4. The traveling guide rail module 4 includes a traveling guide rail 41. The traveling guide rail 41 is distributed on the walkways on both sides of the photovoltaic modules 10 of the photovoltaic roof 9, and is used to guide or limit the traveling path of the power cart 101 to slide along the rail, ensuring that the power cart 101 moves along the rail, such as linear motion, etc., and avoiding the deviation of the power cart 101 during the movement process.

[0041] In addition, in order to ensure the safe storage of the fire blanket 21, the fire blanket protection box module 2 also includes a fire blanket protection shell 22, a fire blanket fixing part 23 and a hand crank 24. The fire blanket 21 and the fire blanket fixing part 23 are located inside the fire blanket protection shell 22, and the hand crank 24 is located outside the fire blanket protection shell 22. The hand crank 24 is fixedly connected to the fire blanket fixing part 23, and the hand crank 24 can drive the fire blanket fixing part 23 to rotate. The first side of the fire blanket 21 is wound around the fire blanket fixing part 23, and the second side is fixed to the power trolley 101. When the power trolley 101 completes the laying of the fire blanket 21, the fire alarm is lifted, and the operation and maintenance personnel can wind up and retract the fire blanket 21 through the hand crank 24, and reset the power trolley 101 at the same time.

[0042] More specifically, the fire blanket protection box module 2 is arranged on the parapet 103, wherein the fire blanket protection shell 22 is fixedly connected to the parapet 103 by expansion bolts 102, and the fire blanket protection box module 2 can be adjusted to a fixed height on the parapet 103 according to the height of the photovoltaic components 10 of the photovoltaic roof 9.

[0043] In addition, in order to adapt to the width of the fire blanket 21 to provide a more comprehensive spreading effect, the power trolley module 1 also includes a fixing rod 15, which is fixedly connected to the power trolley 101, and the fixing rod 15 is fixedly connected to both sides of the trolley compartment 11. The second side of the fire blanket 21 is fixedly connected to the fixing rod 15 by means of bonding such as structural adhesive. The length of the fixing rod 15 is greater than or equal to the width of the fire blanket 21, so that when the power trolley 101 moves, the fixing rod 15 can fully pull open the fire blanket 21 to lay the photovoltaic roof 9.

[0044] On this basis, the number of power carts 101 is at least two, the number of fixed rods 15 is at least one, and the power cart 101 is arranged at the end of the fixed rod 15. When there are two power carts 101 and one fixed rod 15, the two power carts 101 are located at both ends of the fixed rod 15, the second side of the fire blanket 21 is fixedly connected to the fixed rod 15, and the two power carts 101 move simultaneously and pull the fire blanket 21 apart. When there are three power carts 101 and two fixing rods 15, the two sides of one power cart 101 are respectively fixedly connected to the inner ends of the two fixing rods 15, and the inner sides of the other two power carts 101 are respectively fixedly connected to the outer ends of the two fixing rods 15. At this time, the two fixing rods 15 can be respectively fixedly connected to the second sides of the two fire blankets 21, and the two fire blankets 21 can be pulled apart synchronously; further, more power carts 101 and fixing rods 15 can be provided to pull apart more fire blankets 21 to meet the needs of photovoltaic roofs 9 and photovoltaic modules 10 of different sizes, which will not be elaborated here.

[0045] Furthermore, the power trolley module 1 further includes an infrared sensor 14. The infrared sensor 14 is disposed on the power trolley 101 and is connected to the system controller 5 to realize the induction detection of obstacles when the power trolley 101 is laying. In this embodiment, parapets 103 are provided not only on one side of the fire blanket protection box module 2, that is, on the starting side of the power trolley 101, but also on the ending side of the power trolley 101. When the power trolley 101 finishes laying, which means when the power trolley 101 runs to the parapet 103 on the other side of the photovoltaic roof 9, the infrared sensor 14 at the front of the power trolley 101 will sense the existence of the parapet 103 as an obstacle and send a signal to the system controller 5, causing the energy storage module 7 to stop discharging and the power trolley 101 to stop running.

[0046] In addition, the exteriors of the power trolley module 1 and the fire blanket protection box module 2 are made of fireproof materials. The outer shell of the power trolley module 1, such as the trolley carriage 11, etc., uses fireproof materials with an outdoor protection level, enabling the power trolley module 1 to operate normally in the outdoor environment and not affecting its normal operation during a fire; the outer shell of the fire blanket protection box module 2, such as the fire blanket protection housing 22, uses fireproof materials with an outdoor protection level to protect the internal fire blanket 21.

[0047] Furthermore, the image-type fire detector module 3 further includes a central processor 32, a host 33, and a display screen 34. The image-type fire detector 31 is connected to the central processor 32, the central processor 32 is connected to the host 33, and the host 33 is connected to the display screen 34. The image-type fire detector module 3 monitors the fire situation on the photovoltaic roof 9. When a fire occurs, the image-type fire detector 31 disposed on the photovoltaic roof 9 transmits the fire signal to the system controller 5, and at the same time collects and processes the video information of the picture through the central processor 32 and uploads it to the host 33 in the background, and the real-time fire situation is displayed on the display screen 34.

[0048] In addition, the distributed photovoltaic power station roof fire treatment system further includes a wireless communication module 8. The wireless communication module 8 is used to realize that the communications of the image-type fire detector module 3, the fire alarm module 6, the power trolley module 1, and the system controller 5 are all wireless communications. Among them, the communications of the image-type fire detector 31, the power trolley module 1, the system controller 5, the fire alarm module 6, and the background are all realized through wireless communications.

[0049] In this embodiment, the distributed photovoltaic power station roof fire treatment system is composed of eight modules in total, including a power trolley module 1, a fire blanket protection box module 2, an image-type fire detector module 3, a traveling rail module 4, a system controller 5, a fire alarm module 6, an energy storage module 7, and a wireless communication module 8.

[0050] In addition, the number of image-type fire detectors 31 can be reasonably configured according to the size of the photovoltaic roof 9, and the image-type fire detectors 31 can also be set at different positions of the photovoltaic roof 9, such as the corners, according to actual needs for more comprehensive induction monitoring; the heights of the trolley carriage 11 and the fixed rod 15 can be reasonably adjusted according to the height of the photovoltaic modules 10 on the photovoltaic roof 9; during use, the power supply for the power consumption of the photovoltaic power station is pulled to the photovoltaic roof 9, and a power socket is installed on the photovoltaic roof 9. During normal operation of the power station, the energy storage module 7 can be charged through this power socket. When it is fully charged, the charge and discharge controller 72 controls to stop charging.

[0051] In this embodiment, the modules can be integrated into the power trolley 101. The system controller 5, the energy storage module 7, the wireless communication module 8, and the motor 13 are arranged in the trolley carriage 11. The fire blanket protection box module 2, the image-type fire detector module 3, and the traveling rail module 4 are arranged on the photovoltaic roof 9. Because of the wireless communication between the modules and the background, the fire alarm module 6 can be arranged in the control room of the photovoltaic roof 9 and the background where the operation and maintenance personnel are located. Similarly, the central processing unit 32, the host 33, and the display screen 34 can be arranged in the control room of the background to alarm and notify the operation and maintenance personnel in the background in time, and the operation and maintenance personnel can view the fire situation through the video. Among them, the power trolley 101 is made of fire-resistant materials, powered by the energy storage module 7 and communicates through the wireless communication module 8 to ensure that the modules can operate normally during a fire without being damaged due to external cables being burned out.

[0052] Among them, the system controller 5 mainly completes the information reception, processing, analysis, and control of the entire system. The system controller 5 is not limited to programming languages, and can be implemented by, for example, PLC, C language, C++, etc. In the processing logic: at the beginning, step S1 is executed; in step S1, the image-type fire detector 31 monitors the photovoltaic roof 9, and step S2 is executed; in step S2, the fire situation of the photovoltaic roof 9 is judged. If there is no fire, it returns to execute step S1.
