[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Please refer to Figures 1-7 A spherical retarder for fire fighting, including sphere 1, the upper and lower ends of sphere 1 are fixedly connected with connecting pipe 2, the inner walls of two connecting pipes 2 are all threadedly connected with connecting bolt 3 connectable with external water pipe, sphere 1 and two connecting pipes 2 are connected with cleaning assembly, two ends of cleaning assembly are located in two connecting pipes 2, and the two ends of cleaning assembly located in two connecting pipes 2 are all connected with limiting assembly, the ends of two limiting assemblies away from each other are all connected with sliding assembly, and the ends adjacent to two connecting bolts 3 of two sliding assemblies are abutted.

[0027] As Figures 1 to 7As shown in the utility model, when the spherical delay device for fire fighting needs to be cleaned inside the sphere 1 after being used for a period of time, first, the alarm valve group water source valve is closed, the pipe network pressure is emptied, then the connecting bolt 3 is separated from the external water pipe, then one of the connecting bolts 3 is screwed out from the connecting pipe 2 in the threaded mode, thereby exposing the connecting pipe 2 of a larger size, and the opening of the other connecting bolt 3 is sealed by the external nut.

[0028] Then, the cleaning liquid is added into the connecting pipe 2 exposed from the opening, the sphere 1 is soaked inside, the related impurities are softened, then the other connecting bolt 3 is opened, at this time, the cleaning assembly is rotated, the sphere 1 inner wall can be scraped by the cleaning assembly, thereby the remaining impurities inside the sphere 1 can be scraped off, then the flushing water pipe is inserted into any one of the connecting pipes 2, and the sphere 1 is flushed, which is convenient and fast and does not have a cleaning dead angle.

[0029] As a preferred scheme of the utility model, the cleaning assembly comprises the scraping strip 6 and the two rotating discs 5, the two ends of the scraping strip 6 are fixedly connected with the sides adjacent to the two rotating discs 5 respectively, the side walls of the two rotating discs 5 are rotatably connected with the inner walls of the two connecting pipes 2 respectively, and the two rotating discs 5 are further abutted with the two limiting assemblies respectively, and the side wall of the scraping strip 6 is slidably connected with the inner wall of the sphere 1.

[0030] More specifically, when the sphere 1 needs to be cleaned inside, the rotating disc 5 is only rotated, the rotating disc 5 can rotate with the scraping strip 6 in the sphere 1, and the sphere 1 inner wall can be scraped by the rotating scraping strip 6, so that the cleaning is realized, which is convenient and fast.

[0031] As a preferred scheme of the utility model, the inner walls of the two sides adjacent to the two rotating discs 5 are fixedly connected with the filter screens respectively, and the two filter screens are located between the two limiting assemblies.

[0032] More specifically, by arranging the filter screens, the too many impurities entering the sphere 1 can be reduced.

[0033] As a preferred scheme of the utility model, the limiting assembly comprises the inner spline 9 and the outer spline 10, one end of the inner spline 9 is fixedly connected with the rotating disc 5, the inner wall of the outer spline 10 is connected with the sliding assembly, and the inner spline 9 and the outer spline 10 are slidably connected.

[0034] More specifically, by arranging the limiting assembly, when the water flows into the sphere 1, the rotation of the rotating disc 5 and the scraping strip 6 caused by the water flow impact can be avoided, thereby the abrasion of the scraping strip 6 is accelerated, and the scraping wall cleaning in the later stage is affected.

[0035] Specifically, in use, the outer spline 10 follows the connecting bolt 3 and the sliding assembly is inserted into the connecting pipe 2, as the outer spline 10 is inserted, the teeth of the outer spline 10 are gradually inserted into the tooth opening of the inner spline 9, then when the outer water pipe is screwed with the connecting bolt 3, the outer water pipe is abutted above the sliding assembly, thereby the sliding assembly cannot be moved, so the rotation of the rotating disc 5 can be limited by the tooth dislocation of the inner spline 9 and the outer spline 10.

[0039] More specifically, by setting the sliding assembly, when the sphere 1 is normally used, because the inner polygonal plate 4 and the polygonal pipe 7 are non-circular, cannot rotate, so the inner spline 9 and the outer spline 10 cannot rotate after being connected.

[0040] As a preferred scheme of the utility model, a sealing ring is arranged at the connecting position of the connecting bolt 3 and the connecting pipe 2.

[0041] More specifically, by setting the sealing ring, the sealing property between the connecting bolt 3 and the connecting pipe 2 can be increased, so that the water in the sphere 1 cannot flow out.

[0042] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
