Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting facilities, in particular to a vertical sidewall type sprinkler head. Background Art

[0002] In fire extinguishing systems, fire sprinklers are one of the main devices and are generally installed in shopping malls, supermarkets, hotels, and suites. When a fire occurs, the thermistor on the sprinkler is heated, causing the solution in the glass tube of the thermistor to burst and open the sprinkler to spray water, thus controlling the fire.

[0003] Patent document CN203525179U discloses a fully automatic drooping fire sprinkler, which includes a threaded tube, a frame, a glass tube, a rotating shaft, a deflector, a top post, and a valve. Its structural features include a valve connected to the threaded tube, two ends of the glass tube connected to the valve and the top post, a frame connected between the top post and the threaded tube, and a rotating shaft connected between the top post and the deflector. The deflector has inclined teeth evenly arranged along the circumference.

[0004] In actual application, the following deficiencies still exist: the splash plate of the existing upright fire sprinkler is usually coaxially arranged with the center of the frame, so the sprinkler scatters water evenly in 360 degrees when spraying. However, for the sprinkler installed on the side wall, since only a very small amount of water is needed on the side facing the wall to effectively extinguish the fire, the uniform water flow distribution will lead to excessive water spraying in the direction of the wall, resulting in a waste of water resources.

[0024] All embodiments of the present invention fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort fall within the scope of protection of the present invention.

[0025] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as referring to the purpose, technical solutions and advantages of the methods. To be clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0026] The deflector disc of existing upright fire sprinklers is usually coaxially arranged with the center of the frame, so the sprinkler sprays water evenly in a 360-degree pattern. However, for sprinklers installed on side walls, only a very small amount of water is needed on the side facing the wall to effectively extinguish the fire. The uniform water flow distribution will result in excessive water spraying in the direction of the wall, resulting in a waste of water resources. To solve the above technical problems, this case proposes the following technical solutions:

[0027] Reference Figures 1 to 6As shown, a vertical sidewall sprinkler, its structure includes: a threaded connection pipe 1, the top ends of the threaded connection pipe 1 have upwardly extending frames 2, the top of the frame 2 is connected by a mounting seat 3, the lower end of the threaded connection pipe 1 is provided with a water inlet, the top is provided with a water outlet, the water outlet is provided with a sealing seat 4, a thermal element 5 is provided between the threaded connection pipe 1 and the sealing seat 4, the top of the mounting seat 3 is fixed with a deflector 6, the deflector 6 and the mounting seat 3 are eccentrically arranged, the end of the deflector 6 closer to the axis of the mounting seat 3 is provided with a downwardly bent deflector 7, the width of the mounting seat 3 to the deflector 6 away from the deflector 7 is greater than the width of the mounting seat 3 to the deflector 7;

[0028] When in use, the threaded connecting pipe 1 is vertically connected to the fire water supply pipe and ensure that it is installed upward. At the same time, the deflector 7 is installed on the side close to the wall; the thermal element 5 keeps the water channel closed in the silent state. After being heated to the rated temperature, the thermal element ruptures and automatically opens the water channel; after opening, the fire water is sprayed from bottom to top through the channel of the threaded connecting pipe 1, and is guided by the coordinated action of the splash plate 6 and the deflector 7. Since the splash plate 6 is eccentrically arranged on the mounting seat 3, and the width from the mounting seat 3 to the splash plate 6 away from the deflector 7 is greater than the width from the mounting seat 3 to the deflector 7, most of the water flow is sprayed along the end of the splash plate 6 away from the deflector 7, and a small amount of water flow is directed downward through the deflector 7 to the wall and sprayed in the lower front, so that the fire sprinkler installed on the side wall can concentrate the water flow mainly on the fire area, ensuring the maximization of the fire extinguishing effect, and a small amount of water flow is sprayed to the side close to the wall, effectively avoiding the waste of fire water, thereby improving the fire extinguishing efficiency.

[0029] Among them, the thermal element 5 is a prior art, and its specific structure and working principle are not described here in detail;

[0030] Furthermore, a plurality of guide teeth 8 extending outward are evenly provided on the edge of the water deflector 6, so that the direction of the water flow is effectively guided by the guide teeth 8, so that the water flow is diffused more evenly and orderly during the spraying process.

[0031] The water splash plate 6 is an umbrella-shaped structure, and the water flow spreads in a hemispherical shape, effectively expanding the coverage of the water flow and ensuring the maximum fire extinguishing effect;

[0032] like Figure 5 As shown, part of the water is sprayed downward and forward along the guide flow bend of the guide plate 7, further improving the fire extinguishing efficiency.

[0033] A fixing groove for fixing the thermal element 5 is provided on the top of the sealing seat 4, and a threaded hole is formed in the mounting seat 3, and a top bolt 9 for supporting the thermal element 5 is connected to the threaded hole through a thread; the thermal element 5 is then firmly fixed by the fixing groove and the top bolt 9, ensuring that it can always be in a fixed position during use to avoid displacement or damage caused by vibration or external force; at the same time, the top bolt 9 is provided to facilitate the installation of the thermal element 5; specifically, during installation, the bottom end of the thermal element 5 is first inserted into the fixing groove, and then the top bolt 9 is rotated downward along the threaded hole until the top bolt 9 abuts against the top of the thermal element 5.

[0034] A sealing ring 10 is further provided between the water outlet of the threaded connecting pipe 1 and the sealing seat 4 to further improve the sealing performance of the water outlet of the threaded connecting pipe 1 and the sealing seat 4. When connected, the sealing ring 10 tightly fits the contact surface between the water outlet of the threaded connecting pipe 1 and the bottom of the sealing seat 4 to prevent water leakage from the joint.

[0035] The sealing seat 4 has a cone structure at the bottom and an open structure at the top. The shape of the cone bottom helps to evenly distribute the water pressure on the sealing seat 4; the open top facilitates the insertion of the thermal element 5 into the fixing groove along the inclined surface.

[0036] The through hole in the middle of the threaded connecting pipe 1 is a channel that is narrow at the top and wide at the bottom. When the water flows through the channel, it can be quickly concentrated and accelerated to form a stronger jet force, thereby increasing the impact force and jet distance of the water flow and improving the fire extinguishing efficiency and coverage.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
