DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1 to Figure 3As shown, a fire extinguishing ball for ejection type fire extinguishing comprises a launching cylinder 1, a positioning base 2 is fixedly mounted on the bottom of the launching cylinder 1, a positioning through hole 3 is opened at the edge of the positioning base 2, an ejection assembly 4 is arranged in the launching cylinder 1, the ejection assembly 4 comprises a fire extinguishing ball body 401, an ejection push plate 402, a positioning groove 403, a sliding support foot 404 and a force storage spring 405, a limiting assembly 5 is arranged on the upper end of the launching cylinder 1, the limiting assembly 5 comprises a plastic limiting rod 501, a limiting metal ring 502, a heat collecting fin 503, a metal baffle 504 and a limiting groove 505, and the fire extinguishing ball body 401 is limited in the launching cylinder 1 by the metal baffle 504.

[0019] An ejection assembly 4 is provided in the launch cylinder 1, and the ejection assembly 4 includes a fire extinguishing ball body 401, an ejection push plate 402, a positioning groove 403, a sliding foot 404 and a force storage spring 405. The force storage spring 405 is installed in the launch cylinder 1. An ejection push plate 402 is provided above the force storage spring 405 in the launch cylinder 1. The sliding foot 404 is fixedly installed on the side wall of the ejection push plate 402. A positioning groove 403 is provided on the upper surface of the ejection push plate 402. The fire extinguishing ball body 401 is provided in the positioning groove 403. The force storage spring 405 will eject the push plate 402 to increase the elastic force, thereby pushing the ejection push plate 402 to move forward. After the ejection push plate 402 moves forward, it will push out the fire extinguishing ball body 401.

[0020] A limiting assembly 5 is provided at the upper end of the launch cylinder 1, and the limiting assembly 5 includes a plastic limiting rod 501, a limiting metal ring 502, a heat collecting fin 503, a metal baffle 504 and a limiting groove 505. The metal baffle 504 is arranged at the upper end of the launch cylinder 1, and a limiting groove 505 is opened on the side wall of the metal baffle 504. A plastic limiting rod 501 is provided in the limiting groove 505. A limiting metal ring 502 is sleeved on the outer side of the plastic limiting rod 501, and a heat collecting fin 503 is fixedly installed on the surface of the limiting metal ring 502. The metal baffle 504 can be limited to the upper end of the launch cylinder 1 by the plastic limiting rod 501. At the same time, the heat collecting fin 503 and the metal baffle 504 can absorb heat to melt the plastic limiting rod 501.

[0021] It should be noted that the utility model is a catapult-type fire extinguishing ball. When it is actually used, the whole device is first fixed on site by bolts. Since a through hole is opened at the upper end of the launch cylinder 1, the plastic limiting rod 501 passes through the launch cylinder 1 through the through hole. The plastic limiting rod 501 is connected to the metal baffle 504 through the limiting groove 505. The metal baffle 504 is limited at the upper end of the launch cylinder 1 by the plastic limiting rod 501. The plastic limiting rod 501 is limited in the metal baffle 504 by the limiting metal ring 502. Therefore, when launching a fire, the heat collecting fins 503 and the metal baffle 504 can absorb heat to melt the plastic limiting rod 501. After the plastic limiting rod 501 melts, the metal baffle 504 will lose its blocking effect. At the same time, since a movable slide groove is provided on the inner wall of the launch cylinder 1, the sliding foot 404 is movably installed in the launch cylinder 1 through the movable slide groove, the fire extinguishing ball body 401 is connected to the ejection push plate 402 through the positioning groove 403, and the ejection push plate 402 is movably installed in the launch cylinder 1 through the sliding foot 404. One end of the storage spring 405 is connected to the bottom of the launch cylinder 1, and the other end of the storage spring 405 is connected to the ejection push plate 402. Therefore, after the metal baffle 504 loses its obstruction, the storage spring 405 will bounce up, so that the ejection push plate 402 pushes the fire extinguishing ball body 401 to pop out. After the ejected fire extinguishing ball body 401 falls into the flame, the dry powder fire extinguishing agent will be quickly released, directly acting on the flame, thereby extinguishing the fire.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
