Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler heads, and more particularly to a fire sprinkler head with high efficiency in extinguishing fires. Background Art

[0002] Fire sprinkler, a type of sprinkler that automatically starts under the action of heat within a predetermined temperature range, or is started by a control device according to a fire signal, and sprays water to extinguish fire according to the designed spraying shape and flow rate. It is part of the sprinkler system;

[0003] Existing fire sprinklers (such as Publication (Announcement) No.: CN218853370U, a new type of fire sprinkler), wherein it is stated that "by setting a rotating bearing, the splash plate has a rotating function. When the heat-sensitive glass ball is broken, water flows out from the threaded connection pipe and impacts the splash slope, providing power for the splash plate to rotate. The rotating splash plate can throw water outward, expand the spraying area, and reduce the number of fire sprinklers installed in the spraying area", and at the same time cooperate with the refinement and divergence effect of water flow rushing on the "splash plate" to improve the water dispersion effect;

[0004] However, the above-mentioned "new type of fire sprinkler" adopts "the splashing slope directly touches the water to produce impact", which also causes the problem of inclined unloading force. That is, in order to increase the centrifugal force, the refinement and divergence effect of the water flow on the "splashing plate" is reduced, which is insufficient for the high efficiency of fire extinguishing. Utility Model Content

[0008] As a preferred technical solution of the utility model, a shielding groove for accommodating the rotating member is provided on the nozzle body so as to vertically block the rotating member.

[0009] As a preferred technical solution of the utility model, the cavity of the through hole above the turbine blade gradually decreases from top to bottom.

The outer side of the elastic column is threadedly connected to the column hole, and the column hole is provided on the nozzle body.

[0012] As a preferred technical solution of the utility model, the elastic column moves between the enclosed multiple groups of turbine blades.

[0013] The beneficial effects of the utility model are as follows:

[0014] By arranging turbine blades 4 on the opposite side of the water receiving end surface of the splash plate 2, water impacting the upper part of the splash plate 2 flows through the through hole 3 to impact the turbine blades 4 to generate a force to drive the splash plate 2 to rotate.

[0018] like Figure 1~2 As shown, this embodiment proposes: a fire sprinkler with high efficiency of fire extinguishing, comprising a sprinkler body 1 (the specific structure can be as follows Figure 1 shown);

[0019] The nozzle body 1 is rotatably connected to the water splash plate 2 via a rotating member (such as Figure 1 As shown in the rod-shaped structure position at the bottom end of the nozzle body 1, the rotating installation is carried out by a rotating member, the rotating member can be a bearing, etc., and the bearing can be a rolling bearing, etc.);

[0020] The two opposite ends of the splash plate 2 receiving water are respectively penetrated by a plurality of through holes 3 (such as Figure 1As shown, the water splash plate 2 receives water at two opposite ends, namely the top and bottom ends, and the through hole 3 penetrates the top and bottom ends of the water splash plate 2). The through hole 3 is provided to provide a spraying effect below the water splash plate 2;

[0021] The water splash plate 2 has a plurality of turbine blades 4 (such as Figure 1 As shown, multiple groups are evenly arranged in a centrally surrounding manner at the bottom of the splash plate 2);

[0022] The through hole 3 flows water to the turbine blade 4 to impact the turbine blade 4 to generate a force that drives the deflector plate 2 to rotate (such as Figure 1 , 2 As shown, the turbine blade 4 is vertically arranged, and one end is curved toward the through hole 3. When water flows through the through hole 3 and contacts the turbine blade 4 vertically downward, a rotational driving force centered around the rotating part is generated, which can drive the splash plate 2 to rotate, providing high efficiency of fire extinguishing.

[0023] The nozzle body 1 is provided with a water passage cavity 6 (such as Figure 1 As shown, the outer portion of the water passage cavity 6 is surrounded by a threaded connecting pipe for connecting water after installation);

[0024] One end of the water passage cavity 6 is connected to the outside of the nozzle body 1, and the other end of the water passage cavity 6 is connected to a water outlet 7, which is centered toward the water receiving end of the splash plate 2 (such as Figure 1 As shown, water is received at the top of the water passage cavity 6, and the flowing water is discharged to the water outlet 7 at the bottom, and then impacts the top of the splash plate 2 in the center to produce a splashing effect).

[0025] The water outlet 7 is tightly fitted with a water blocking plug 8, and an elastic column 10 is provided outside the water blocking plug 8, and a glass column 9 is fitted and supported stably therebetween. The outer side of the elastic column 10 is threadedly connected to the column hole 11, and the column hole 11 is provided on the nozzle body 1 (the water blocking plug 8 is used to block the water outlet 7, and the elastic column 10 is pre-threaded in the column hole 11, and then the glass column 9 is set between the elastic column 10 and the water blocking plug 8. The elastic column 10 is operated to adjust the position to press the glass column 9. The glass column 9 is a heat-sensitive glass column. After the temperature is sensed and broken, the water blocking plug 8 falls off and can be used for flushing).

[0026] The elastic rod 10 moves between the enclosed multiple groups of turbine blades 4 (such as Figure 1 As shown, turbine blades 4 are arranged in a central ring at the bottom of the splash plate 2, and there is a channel in the center for the elastic column 10 to move. The elastic column 10 can be a threaded rod. As shown in the figure, a "cross" and other bayonet is arranged at the bottom of the threaded rod, so that the above-mentioned operations of disassembly, assembly, adjustment and use can be carried out). Embodiment 2:

[0027] like Figure 1As shown, the difference between it and embodiment 1 is that: the nozzle body 1 is provided with a shielding groove 5 for accommodating the rotating member so as to vertically block the rotating member (such as Figure 1 As shown, when the nozzle body 1 is installed for downward spraying, the rotating part is on the inner side of the shielding groove 5, that is, the top of the rotating part will not be directly affected by the vertical falling and deposition of dust and other microparticles. When the rotating part is the above-mentioned rolling bearing, it is easy to accumulate dirt and cause blockage, affecting the rotation use). Embodiment 3:

[0028] like Figure 1 As shown, the difference between it and embodiment 1 or embodiment 2 is that the cavity of the through hole 3 above the turbine blade 4 gradually decreases from top to bottom (such as Figure 1 As shown, the cavity space of the through hole 3 gradually decreases from top to bottom. When the water flow hits the splash plate 2, the water entering the through hole 3 increases the impact force on the turbine blade 4 through the effect of space contraction, thereby improving the rotation ability and further improving the water throwing effect).

[0029] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
