Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] Please refer to Figs. 1 to 4 The back-carrying fire pump in the embodiment comprises a back plate 1, and a filter spraying structure is arranged on the outer side of the back plate 1.
[0023] The filter spraying structure comprises a first fixed plate 2 and a second fixed plate 3 fixedly connected to the left side of the back plate 1, the top of the first fixed plate 2 is fixedly connected with a fire pump 4, the top of the second fixed plate 3 is fixedly connected with a water collecting tank 5, the inner side of the water inlet pipe of the fire pump 4 is fixedly connected with a threaded sleeve 6, the inner side of the threaded sleeve 6 is threadedly connected with a filter frame 7, the outer side of the filter frame 7 is fixedly connected with a holding handle 8, the top of the water inlet pipe of the fire pump 4 is fixedly connected with a conveying pipe 9, the right side of the water collecting tank 5 is fixedly connected with a threaded pipe 10, and the front end of the threaded pipe 10 is threadedly connected with an atomizing nozzle 11. By arranging the filter spraying structure, the water source filtering function and the spray cooling function are realized, the foreign matters in the external natural water source can be filtered, so that the probability of pipe blockage is reduced, at the same time, the water mist can be continuously sprayed on the firefighters, so as to reduce the influence of the hot air on the firefighters, and the utility model is more convenient to use.
[0024] When the fire pump 4 extracts the external natural water source for fire extinguishing, the filter frame 7 on the inner side of the water inlet pipe of the fire pump 4 can block the foreign matters by using the metal filter grid on the inner side for filtering the foreign matters, so as to avoid the foreign matters entering the inside of the fire pump 4.
[0025] At the same time, part of the water drawn into the water inlet pipe of the fire pump 4 will be introduced into the water collecting tank 5 through the conveying pipe 9, and finally sprayed on the firefighters or around through the atomizing nozzle 11 at the front end of the threaded pipe 10, so as to reduce the influence of the hot air on the firefighters.
[0026] In addition, since the filtering frame 7 is threadedly connected to the inner side of the threaded sleeve 6 and the atomizing nozzle 11 is threadedly connected to the front end of the threaded pipe 10, the effect of easy disassembly is achieved, and the staff only needs to rotate the filtering frame 7 and the threaded sleeve 6 counterclockwise to release the threaded connection of the two, so as to take them down for maintenance or cleaning.
[0027] It should be noted that the first fixed plate 2 is consistent in size with the second fixed plate 3 and is symmetrically distributed up and down.
