Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically a fire sprinkler head fixing device. Background Technology

[0002] In the field of fire protection technology, fire sprinklers are key components of automatic sprinkler systems. When a fire occurs and the ambient temperature rises to a certain level, the sprinklers activate to spray water and extinguish the fire. They can quickly control the spread of fire, reduce fire hazards, and protect the lives and property of people. They are widely used in various types of buildings.

[0003] When fire sprinklers are protected, the water spray source may be obstructed, leading to a conflict between protecting the fire sprinklers and their fire extinguishing efficiency. Therefore, there is an urgent need to develop a fire sprinkler fixing device to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fire sprinkler fixing device, which solves the practical contradiction between fire sprinkler protection and fire extinguishing efficiency caused by the easy obstruction of the fire sprinkler's water spray source when the fire sprinkler is protected.

[0005] To achieve the above objectives, this utility model provides a fire sprinkler fixing device through the following technical solution: a connecting pipe is provided, a fixing plate is fixedly connected to the outer side of the bottom end of the connecting pipe, and a fire sprinkler for spraying water to the environment is fixedly connected to the bottom end of the connecting pipe.

[0006] It also includes an automatic separation mechanism for protection, which includes a shaft frame located on the outside of the fixed plate. A protective cage is movably installed on the inside of the shaft frame via a rotating shaft. A fuse is fixed to the side of the protective cage away from the shaft frame. The fuse passes through the inside of the fixed plate and is wrapped with a connecting block. The connecting block is fixed in contact with the fixed plate.

[0007] Preferably, it also includes a heat dissipation and anti-deformation mechanism, which includes a threaded seat sleeved on the outside of the connecting pipe and threadedly connected to the outside of the connecting pipe. Multiple sets of elastic members are fixedly connected to the top of the threaded seat, and a heat dissipation plate is fixedly connected to the top of the elastic members. A heat-conducting component for absorbing and conducting heat from the ceiling is provided on the top of the heat dissipation plate.

[0008] Preferably, the heat-conducting component includes a heat-conducting pad attached to the top of the heat sink, the heat-conducting pad being used to contact the ceiling and absorb heat, and thermal grease being applied between the heat-conducting pad and the heat sink.

[0009] Preferably, the bottom edge of the heat sink is fixed with multiple sets of strip-shaped heat dissipation fins, and the heat dissipation fins are made of aluminum alloy.

[0010] Preferably, the elastic element has a Z-shaped cross-section and is made of a nickel-based alloy, which can adapt to thermal expansion and contraction stress.

[0011] Preferably, the fuse is made of a low-melting-point lead-tin alloy, and its melting temperature matches the breaking temperature of the glass bulb of the fire sprinkler head.

[0012] This utility model provides a fire sprinkler head fixing device. Compared with the prior art, it has the following advantages.

[0013] 1. During a fire, the ambient temperature rises, and the fuse matching the breaking temperature of the glass bulb of the fire sprinkler blows, releasing the restraint on the protective cage. Under the action of gravity, the protective cage flips and opens around the axis frame, without obstructing the sprinkler head from spraying water. This combines safety protection and automatic fire separation functions. In daily life, the protective cage can prevent the fire sprinkler head from being hit, resolving the contradiction between protection and fire extinguishing efficiency. It is suitable for places with few personnel and many mechanical operations.

[0014] 2. The screw-in seat moves upward along the thread of the connecting pipe, and the elastic element drives the heat sink and heat conduction plate to move upward, making close contact with the ceiling. The elastic element compensates for small gaps. In case of fire, the ceiling heats up due to high temperature, the heat conduction plate absorbs heat, and the heat is transferred to the heat sink through the thermal grease. The heat sink fins increase contact with the air to dissipate heat. This device has both installation adaptation and high temperature heat dissipation functions, solves the problem of installation fit, and avoids the ceiling from being damaged by high temperature, which will affect the sprinkler head. It is suitable for building scenarios that are prone to high temperature. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] First implementation method:

[0021] refer to Figure 1-3 A fire sprinkler fixing device includes a connecting pipe 1, a fixing plate 101 fixedly connected to the outer side of the bottom end of the connecting pipe 1, and a fire sprinkler 102 for spraying water to the environment fixedly connected to the bottom end of the connecting pipe 1.

[0022] It also includes a protective automatic separation mechanism 2, which includes a shaft frame 201 disposed on the outside of the fixed plate 101. A protective cage 202 is movably installed on the inside of the shaft frame 201 via a rotating shaft. A fuse 203 is fixedly connected to the side of the protective cage 202 away from the shaft frame 201. The fuse 203 penetrates the inside of the fixed plate 101 and is wound around and connected to a connecting block 204. The connecting block 204 is fixed in contact with the fixed plate 101.

[0023] Fuse 203 is made of a low-melting-point lead-tin alloy, and its melting temperature matches the glass bulb breaking temperature of the fire sprinkler head 102.

[0024] The operator flips the protective cage 202 so that it flips around the shaft 201 until it is in a closed state with the fixed plate 101. Then, the fuse 203 is passed through the inside of the fixed plate 101 and wrapped around the outside of the connecting block 204, thereby fixing the protective cage 202 to the outside of the fire sprinkler 102 and forming physical protection for the outside of the fire sprinkler 102.

[0025] When a fire occurs, the ambient temperature rises, and the fuse 203 will melt due to the high temperature. Its melting temperature matches the glass bulb breaking temperature of the fire sprinkler head 102, thus losing its restraint on the protective cage 202. Under its own weight, the protective cage 202 automatically flips to the open state with the shaft frame 201 as the axis, avoiding the water spray path of the fire sprinkler head 102 and ensuring that the water sprayed by the fire sprinkler head 102 sprays to the area below. This structure realizes the dual functions of safety protection and automatic fire separation.

[0026] In daily use, the protective cage 202 can prevent damage to the fire sprinkler head 102 from collisions, such as scratches during the handling of goods in the warehouse. It solves the practical contradiction between protecting the fire sprinkler head 102 and the fire extinguishing efficiency. It is suitable for factories, logistics warehouses and other places with little personnel activity and frequent mechanical operations.

[0027] Second implementation method:

[0028] When a fire occurs, the ceiling may crack due to structural deformation caused by localized overheating, the embedded parts may loosen, and flammable decorative materials may be ignited, which in turn affects the stability of the fire sprinkler installation.

[0029] refer to Figure 3 In the second embodiment of this utility model, a heat dissipation and anti-deformation mechanism 3 is also included. The heat dissipation and anti-deformation mechanism 3 includes a threaded seat 301 sleeved on the outside of the connecting pipe 1, and the threaded seat 301 is threadedly connected to the outside of the connecting pipe 1. Multiple sets of elastic members 302 are fixedly connected to the top of the threaded seat 301. A heat dissipation plate 303 is fixedly connected to the top of the elastic member 302, and a heat conduction component for absorbing and conducting heat from the ceiling is provided on the top of the heat dissipation plate 303.

[0030] The heat-conducting component includes a heat-conducting plate 305 attached to the top of the heat sink 303. The heat-conducting plate 305 is used to contact the ceiling and absorb heat. Thermal grease 304 is applied between the heat-conducting plate 305 and the heat sink 303. Multiple sets of strip-shaped heat dissipation fins 306 are fixed to the bottom edge of the heat sink 303. The heat dissipation fins 306 are made of aluminum alloy. The elastic member 302 has a Z-shaped cross section and is made of nickel-based alloy to adapt to thermal expansion and contraction stress.

[0031] After connecting the connector 1 to the fire pipe and installing it in the designated area, the operator rotates the threaded seat 301, causing the threaded seat 301 to move upward along the thread on the outside of the connector 1. The threaded seat 301 drives the heat sink 303 to move upward synchronously through the elastic element 302. The heat sink 303 then drives the heat conduction plate 305 to make close contact with the ceiling or ceiling surface.

[0032] At this time, the elastic component 302 can compensate for the small gap between the heat conduction plate 305 and the ceiling due to its high elasticity, such as uneven ceiling surface or plaster layer error, ensuring that the heat conduction plate 305 always stays in contact with the ceiling.

[0033] When a fire occurs, the ceiling temperature will rise sharply due to flame radiation and high-temperature smoke baking, which can easily cause local overheating, expansion and deformation or material deterioration, such as plasterboard cracking and wood decorative layer carbonization. At this time, the heat conduction plate 305 will quickly absorb the heat generated by the high temperature of the ceiling and efficiently transfer it to the heat dissipation plate 303 by reducing thermal resistance through the thermal grease 304. The heat dissipation fins 306 at the bottom of the heat dissipation plate 303 will increase the contact area with the air and quickly dissipate the heat to the surrounding environment, thus achieving active heat dissipation of the ceiling.

[0034] It achieves a combination of installation adaptation and high-temperature heat dissipation. On the one hand, the elastic compensation of the elastic component 302 solves the installation fit problem caused by the difference in the flatness of different ceiling surfaces. On the other hand, in the event of a fire, the heat conduction component quickly conducts and dissipates the heat from the ceiling, preventing the ceiling from undergoing structural deformation due to local overheating, such as ceiling cracking, loosening of embedded parts, or ignition of flammable decorative materials, thereby protecting the installation stability of the fire sprinkler head 102.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
