Detailed Description
The utility model is described in further detail below with reference to the drawings and the specific examples.
As shown in fig. 1 to 4, the nozzle structure of the external dry powder device comprises an external nozzle 2 connected with the area where the nozzle 1.1 of the dry powder extinguishing device 1 is positioned, and a plurality of guide vanes 3 inclined in the direction are arranged at the outlet position of the external nozzle 2. By arranging the external nozzle 2, the range of the dry powder sprayed by the dry powder extinguishing device 1 can be enlarged, the spraying range of the dry powder is enhanced, and the extinguishing capability of the extinguishing device with the same dosage of dry powder is improved.
Preferably, the external nozzle 2 is in an annular structure, and is fixedly sleeved with the peripheral area where the nozzle 1.1 of the dry powder extinguishing device 1 is located.
Preferably, a plurality of bending feet 4 are arranged at the end part of the external nozzle 2, and the bending feet 4 are sleeved and fixed with the peripheral area where the nozzle 1.1 is positioned through an annular hoop 5. As shown in the figure, the external nozzle 2 is sleeved on the area where the nozzle 1.1 of the dry powder extinguishing device 1 is located, then the annular hoop 5 is sleeved on the outer surfaces of the plurality of bending feet 4, after the annular hoop 5 is locked, the bending feet 4 can be fixed on the peripheral area where the nozzle 1.1 is located, namely, the external nozzle 2 is sleeved and fixed on the peripheral area where the nozzle 1.1 is located, and due to the blocking and limiting effects of the bending feet 4, falling between the bending feet 4 and the annular hoop 5 can be effectively prevented, namely, falling of the external nozzle 2 from the peripheral area where the nozzle 1.1 is located is prevented.
Preferably, the inclination directions of the plurality of guide vanes 3 arranged at the outlet position of the external nozzle 2 are consistent. As shown in fig. 2, the inclination directions of the plurality of guide vanes 3 may be set to be uniform according to actual conditions, and for example, it is necessary to intensively extinguish a fire in a certain direction.
Preferably, the plurality of guide vanes 3 arranged at the outlet position of the external nozzle 2 are divided into a plurality of groups according to different inclination directions. As shown in fig. 3 and 4, the plurality of guide vanes 3 may be divided into a plurality of groups according to different inclined directions according to actual situations, for example, the spraying range needs to be enlarged, so that the whole space area is filled with the dry powder as soon as possible, and this way can be adopted.
For example, the following two embodiments:
example 1: as shown in fig. 3, the plurality of guide vanes 3 are divided into two groups according to the inclined direction and are arranged oppositely. Thus, the dry powder can be sprayed in the left and right oblique directions.
