Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler nozzles, in particular to a multifunctional environmentally friendly and safe fire sprinkler nozzle. Background Art

[0002] Fire sprinkler heads are an important part of fire sprinkler systems. They are usually installed on the ceiling or walls of buildings to automatically spray water to extinguish fires when a fire occurs. This type of sprinkler is designed to be activated quickly at the initial stage of a fire, and to control the spread of the fire by spraying water mist or water flow, thereby buying precious time for personnel evacuation and firefighters' rescue work.

[0003] The working principle of fire sprinkler nozzles mainly relies on heat-sensitive components, such as glass balls or fusible elements. When a fire occurs, as the temperature rises, these heat-sensitive components will break or melt, causing the sprinkler head to open and start spraying water.

[0004] However, when the thermal element fails for various reasons, it will burst without a fire, causing the fire sprinkler to spray water without a fire. This will not only waste water resources, but also cause environmental damage and economic losses. At present, the fire sprinkler heads on the market are often not equipped with valves, and users cannot stop the water from spraying out. This will cause the fire sprinkler heads to spray water for a long time without a fire, which will further cause losses. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art and proposes a multifunctional environmentally friendly and safe fire sprinkler.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5 A multifunctional environmentally friendly and safe fire sprinkler head comprises a fire sprinkler head body 1, a water spray port 2 is arranged on the fire sprinkler head body 1, a thermosensitive glass tube assembly 11 is arranged on the water spray port 2, and a water retaining seat 3 is arranged on the water spray port 2 on the outside of the thermosensitive glass tube assembly 11. A mounting seat 4 is fixedly arranged on one side of the water retaining seat 3 on the fire sprinkler head body 1, and a mounting cavity 41 is provided inside the mounting seat 4, a water retaining plate 6 is movably arranged in the mounting cavity 41, and the water retaining plate 6 is fixed by a limit block 9. When the thermosensitive glass tube assembly 11 is overheated and bursts, water flows out from the water spray port 2 in the fire sprinkler head body 1. It is worth noting that the specific structure and working mode of the fire sprinkler head body 1 and the thermosensitive glass tube assembly 11 are both existing technologies currently disclosed on the market, which are common knowledge known to those skilled in the art, and do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0022] Among them, multiple connecting members 31 are fixedly arranged on the outside of the water spout 2, and the other ends of the connecting members 31 are fixedly connected to the water retaining seat 3, and the height of the connecting members 31 is the same as the height of the water retaining plate 6. By inserting the water retaining plate 6 into the water retaining seat 3, the water spout 2 can be blocked by the water retaining plate 3.

[0023] A through hole 42 is provided on the outer side of the mounting seat 4 , and a limiting groove 61 is provided in the middle of the side of the water retaining plate 6 facing the through hole 42 corresponding to the through hole 42 , and both the through hole 42 and the limiting groove 61 are adapted to the limiting block 9 .

[0024] Among them, the outer side of the mounting seat 4 is fixedly provided with an outer plate 5 through a connecting column, and a plurality of springs 7 are installed on the inner wall of the outer plate 5, and the other ends of the springs 7 are connected to the limit block 9. A connecting handle 8 is fixedly provided on the outer side of the limit block 9, and the other end of the connecting handle 8 passes through the middle of the outer plate 5. The limit block 9 can be driven to move by the spring 7 and the connecting handle 8. When the limit block 9 passes through the through hole 42 and is inserted into the limit groove 61, the water baffle 6 can be fixed, so that the water baffle 6 will not accidentally block the water spout 2 in the case of fire extinguishing.

[0025] Among them, a sealing pad is laid on the side of the water baffle plate 6 facing the water spout 2, and an anti-skid pad is laid on the inner wall of the water baffle seat 3 at the part in contact with the water baffle plate 6. By setting the sealing pad, the sealing performance of the water baffle plate 6 when blocking the water spout 2 can be improved, and the friction force on the anti-skid pad can make the water baffle plate 6 stably blocked at the water spout 2.

[0026] In this embodiment, when the heat-sensitive glass tube assembly 11 bursts due to high temperature, water flows out from the water outlet 2 in the fire sprinkler body 1. If no fire is found at this time, and the heat-sensitive glass tube assembly 11 bursts due to other reasons, the user can block the water outlet 2 with the water baffle 6 to prevent a large amount of water from flowing out.

[0027] Furthermore, when the user needs to block the water spout 2, the connection handle 8 can be pulled outward, and the limit block 9 can be synchronously moved outward, and the spring 7 is compressed. When the limit block 9 leaves the limit groove 61 on the water baffle 6, the user can directly move the water baffle 6 in the installation cavity 41 into the water baffle seat 3. In this way, the water spout 2 can be blocked by the water baffle 6 in the water baffle seat 3. When the water spout 2 is blocked, the water flow temporarily stops spraying, and at this time, the fire sprinkler body 1 can be replaced by professional maintenance personnel.

[0028] Furthermore, when a fire occurs, there is no need to block the water outlet 2. At this time, due to the setting of the spring 7, the limit block 9 can be stably stuck in the limit groove 61, so that the water baffle 6 will not move, so that in an emergency, there will be no more serious consequences due to the water baffle 6 blocking the water outlet 2.

[0029] In the utility model, when the heat-sensitive glass tube assembly 11 bursts due to high temperature, water flows out from the water outlet 2 in the fire sprinkler body 1. If no fire is found when the water flows out, the user can block the water outlet 2 by the water baffle 6 to prevent a large amount of water from flowing out, and wait for professionals to replace the fire sprinkler body 1. In this way, the fire sprinkler body 1 can be prevented from spraying a large amount of water when there is no fire, thereby achieving the purpose of reducing economic losses and saving water resources.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
