Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing for power generation equipment, and particularly relates to a fire monitoring sprinkler system applicable to a photovoltaic power station plant area and its supporting devices. Background Art

[0002] In a mountain high - support photovoltaic power station, since it is impossible to level the installation site of photovoltaic modules, and the installation position of photovoltaic modules is relatively high, there are large fire safety hazards due to the withering of annual herbaceous plants under the modules in winter. In the photovoltaic power station plant area where photovoltaic modules have been erected, it is necessary to regularly prune and clean the withered grass manually, and there is a vacuum period when the plant area is covered with withered grass. Due to the huge area of the photovoltaic power station, when a fire breaks out, the power station operation and maintenance personnel cannot reach the scene in time to quickly extinguish the fire. However, the photovoltaic power station covers a huge area, and the photovoltaic panels (photovoltaic modules) are flammable materials, so the fire is likely to spread rapidly, and it is impossible to effectively prevent the spread of the fire. This belongs to passive fire extinguishing. Moreover, due to the huge area of the photovoltaic power station plant area, how to effectively achieve fire monitoring and control is the key point and a problem faced by those in the field.

[0028] Such as Figure 1 Figure 2As shown in the figure, a fire monitoring and sprinkler system applicable to a photovoltaic power station includes several string fire linkage controllers 1. The string fire linkage controllers 1 are connected to a zone controller 6 arranged outside the photovoltaic string 100 area. Nine photovoltaic strings 100 form a fire control zone, and the nine photovoltaic strings are arranged in 3 columns, that is, a 3+3+3 design, and each fire control zone is provided with a string fire linkage controller 1 for control.

[0029] Flame detectors 4 are installed on the photovoltaic string 100 through quick installation frames. The flame detectors 4 transmit signals to the string fire linkage controller 1 of this fire control zone. There are 6 flame detectors 4, and 3 flame detectors 4 are arranged in each of the left and right columns.

[0030] The string fire linkage controller 1 controls the opening and closing of the water inlet valves 2 on the water pipes 3. The water inlet valves 2 are electromagnetic water inlet valves. There are 2 water inlet valves 2, which respectively control the left and right water pipes 3. The water pipes 3 are divided into left and right pipelines through branch heads and are connected to the fire extinguishing nozzles 5 near the photovoltaic string 100 through the water pipes 3. The fire extinguishing nozzles 5 can adopt spiral nozzles for fire fighting, that is, using the torsion of the liquid to rotate and spray, and spraying water through the splash plate of the spray head. It is a common fire fighting equipment.

[0031] It also includes a water storage tank 8. The water pipes 3 are connected to a water pump 7. The water pump 7 is connected to a fire fighting pressure stabilizing tank 9 through the water pipes 3. The fire fighting pressure stabilizing tank 9 is connected to the water storage tank 8 through the water pump 7 and the water pipes 3. The zone controller 6 controls the opening and closing of the water pump 7.

[0032] The zone controller 6 is connected to a storage battery 11, and the storage battery 11 is connected to a photovoltaic charging circuit 12.

[0033] The zone controller 6 is connected to a monitoring receiver 13 of a monitoring system 14 through a wireless module, and the monitoring system 14 is connected to an alarm 10.

[0034] When a fire occurs, the flame detectors 4 arranged under the photovoltaic string support are triggered. The flame detectors 4 transmit signals to the linkage controller 1. The linkage controller 1 transmits the signals to the water inlet valves 2 and the zone controller 6. After receiving the signals, the water inlet valves 2 become in the open state. After receiving the signal from the linkage controller 1, the zone controller 6 turns on the water pump 7. The water pump 7 pushes the pressurized fire extinguishing agent from the water storage tank 10 to the fire fighting pressure stabilizing tank 9, and the water pump 7 pushes the pressurized fire extinguishing agent from the fire fighting pressure stabilizing tank 10 to the fire extinguishing nozzles 5. The fire extinguishing nozzles 5 spray out the fire extinguishing agent to extinguish the fire. Embodiment

[0035] In the system of Embodiment 1, the flame detectors 4 and the fire extinguishing nozzles 5 are deployed on the brackets under the components of the photovoltaic power station. The fire below is sensed through the flame detectors, and the fire sprinkler system (fire extinguishing nozzles, water pumps, fire fighting pressure stabilizing tanks, water inlet valves, etc.) is activated to extinguish the fire. At the same time, the alarm is triggered for alarm and displayed in the monitoring system.

[0036] As Figures 3 - 7 shown, the flame detector 4 and the fire extinguishing nozzle 5 are installed on the bracket under the photovoltaic power station components by means of a quick mounting bracket 15. The quick mounting bracket 15 includes a clamping mounting seat 1501. The clamping mounting seat 1501 is in a clamp shape (U-shaped). A hexagonal column 1502 is installed on the clamp end face. An installation ring 1506 for installing the flame detector 4 or the fire extinguishing nozzle 5 is arranged at the other end of the hexagonal column 1502. The hexagonal column 1502 and the installation ring 1506 can be connected by welding. The flame detector 4 or the fire extinguishing nozzle 5 can be installed on the installation ring 1506 by thread installation or other reliable equivalent fastening installation methods.

[0037] Furthermore, a threaded hole 1503 is axially opened on the end face of the hexagonal column 1502, and a hexagonal hole 1504 is correspondingly opened on the end face of the clamping mounting seat 1501. The hexagonal column 1502 can be inserted into the hexagonal hole 1504. After insertion, a screw passes through the hexagonal hole 1504 and is threadedly connected with the threaded hole 1503 to fasten the hexagonal column 1502 and the hexagonal column 1502 together. The setting of the hexagonal column 1502 and the hexagonal hole 1504 can realize the adjustment of six angles of the installation ring 1506. Of course, similarly, if multiple angle adjustments are to be realized, an octagonal column or a dodecagonal column can be used. However, according to the actual use situation, the structure of the hexagonal column 1502 can already meet the adjustment requirements of the flame detector 4 or the fire extinguishing nozzle 5.

[0038] The clamping mounting seat 1501 can be quickly clamped by passing a bolt and a nut through the clamping through hole 1505. Of course, in the present utility model, the bracket under the photovoltaic power station components shown is square. When the bracket is circular, an arc surface can be opened on the inner side of the clamping mounting seat 1501 to meet the clamping requirement, which is a common design.

[0039] The present utility model has been described in detail through specific and preferred embodiments. However, those skilled in the art should understand that the present utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
