Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and particularly relates to an intelligent fire extinguishing device for a wind turbine generator set. Background Art

[0002] A wind turbine generator set includes a wind wheel and a generator; the wind wheel consists of blades, a hub, reinforcement members, etc.; it has functions such as the blades rotating by the wind force to generate electricity and the generator head rotating. Once a fire breaks out in a wind turbine generator set, if it cannot be extinguished in time, it will cause huge economic losses and hazards.

[0003] Chinese Patent with publication number CN215608922U discloses an induction type intelligent fire-fighting device for a wind turbine generator set, including a fixed box and a box door. An opening is formed on the front side of the fixed box, the box door is hinged at the opening on the front side of the fixed box, a limiting mechanism is arranged on one side of the box door, and the box door is fixedly connected with the fixed box through the limiting mechanism. The limiting mechanism includes a magnet and an iron sheet. A fixed rod is fixedly arranged at the top of the fixed box, and a fixing mechanism is arranged at the top of the fixed rod. The fixing mechanism includes two connecting rods, two clamping frames and four U-shaped blocks. A fire extinguishing mechanism is arranged at the bottom end of the inner cavity of the fixed box, and the fire extinguishing mechanism includes a fixed block and a carbon dioxide storage tank with a built-in electromagnetic valve.

[0004] There are still certain deficiencies in the above-mentioned intelligent fire-fighting device in the prior art during actual use. For example, when the fire-fighting device is in the fire extinguishing state, the spray head connected to the lower end of the conduit can only vertically downward extinguish the fire on the wind turbine generator set. However, as is well known, the structure of the wind turbine generator set itself is not concentrated in one place and is basically distributed along the wind wheel shaft. Therefore, this fixed-type fire extinguishing spray head can only achieve fire extinguishing with a small coverage area and cannot expand the fire extinguishing range of the wind turbine generator set.

[0029] Reference Figure 3 , symmetric support plates 11 are fixedly installed at the lower end of the mounting box 1. Rotating rods 12 are symmetrically fixedly installed on the outer wall of one end of the swing rod 706 close to the sector gear 705. The end of the rotating rod 12 away from the swing rod 706 is rotatably connected to the opposite side of the adjacent support plate 11. The rack 704 meshes and drives the sector gear 705, which can make the swing rod 706 rotate between the support plates 11.

[0032] Principle of use and advantages: During use, the smoke sensor 101 monitors the smoke concentration around the unit, and the photosensitive sensor 102 monitors the light intensity of the fire around the unit. When a fire occurs, the monitoring data is fed back to the control module 105. When any one of the smoke concentration value or the light intensity value reaches the set value, the control module 105 controls the solenoid valve to open, so that the carbon dioxide storage tank 103 releases carbon dioxide and discharges it through the nozzle 4 connected by the connecting hose 3 to extinguish the generator set;

[0033] During the fire extinguishing process, the nozzle 4 is fixed at the lower end of the swing rod 706. By controlling the forward and reverse rotation of the drive motor 702 by the control module 105, the output end of the drive motor 702 drives the first screw rod 703 to rotate between the mounting blocks 701. The rotation of the first screw rod 703 causes the rack 704 threadedly connected to the outside to slide back and forth at the lower end of the mounting box 1. The rack 704 meshes with the sector gear 705 on the swing rod 706. At the same time, the swing rod 706 rotates between the support plates 11. Meanwhile, the swing rod 706 drives the nozzle 4 at the lower end to swing left and right, which can expand the fire extinguishing range of the generator set and perform rapid and effective fire extinguishing operations.
