Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fire-fighting equipment, more specifically to a suspension type spray head for fire-fighting equipment. BACKGROUND

[0002] A fire sprinkler is a key safety device for an automatic water sprinkler system. It is usually installed inside a building and can be activated by heat or by a control device in response to a fire signal. When activated, it sprays water in a predetermined pattern and at a predetermined rate to extinguish the fire. The existing fire sprinkler has the following disadvantages during use: first, the water spraying range is limited, and only a fire extinguishing area in the form of a water spray pattern is formed below the sprinkler, which cannot be expanded to a wider range; second, the fire extinguishing method is limited, and only one type of sprinkler is available, which produces a water spray in the form of a water spray pattern. However, fires often originate from a single large ignition point, especially around the sprinkler. Since the sprinkler only has a water spray pattern, it cannot quickly extinguish the fire, thereby losing control of the fire situation. To address this issue, the present inventors have proposed a suspension type spray head for fire-fighting equipment to effectively extinguish fires by providing two different water spraying methods. In addition to the conventional water spray pattern, a direct jet sprinkler is added to directly spray some ignition points and increase the function of directly extinguishing fires.

[0003] To increase the spraying range of the sprinkler during fire extinguishing and facilitate faster fire extinguishing, a fire sprinkler is disclosed in Chinese Patent Application No. CN222150784U. The utility model includes a fixed head, a plug is inserted into the bottom of the fixed head, a conical filter screen is arranged in the fixed head, the filter screen is located above the plug, a fixed shaft is fixedly connected to the top of the filter screen, a fixed frame is fixedly connected to the circumference of the fixed shaft, a plurality of inclined drive plates are fixedly connected to the bottom of the fixed frame, a brush plate for cleaning the surface of the filter screen is fixedly connected to the inner wall of the circumference of the fixed head, and a communication residue collection box is fixedly connected to one side of the fixed head. The filter screen filters the fire water to prevent impurities from blocking the channel. The rotating filter screen and brush plate cooperate to concentrate impurities in the residue collection box, avoiding affecting the use of the filter screen. During the spraying process of the fire water, the water flow is guided by the arc splash plate, causing some of the fire water to be thrown further away, thereby increasing the fire extinguishing range.

[0004] The scheme still has some deficiencies in application, since most of the fires are caused by a fire point at the beginning, if the fire point can be directly sprayed to extinguish at the beginning, a lot of loss can be reduced, and the safety factor is greatly improved, meanwhile, the spraying shape of the water spraying fire extinguishing mode is not obvious enough to prevent fire extinguishing, and the spraying shape of the mist spraying fire extinguishing mode is more effective, therefore, the structure of the nozzle needs to be improved, so that the nozzle has a wider and more accurate fire extinguishing mode, and the practicality of the nozzle is further improved.
