Description

Technical Field

[0001] The invention relates to the technical field of fire protection systems, in particular to a high-rise building fire sprinkler and fire barrier system. Background Art

[0002] High-rise building fire sprinkler and fire barrier systems are important facilities in high-rise buildings for preventing, controlling and extinguishing fires. Usually, when a fire occurs, the smoke can be detected in time through sensors, and then the sprinklers can be activated to achieve fire barrier and automatic fire extinguishing through sprinklers to reduce risks.

[0003] It is found during the use of the existing high-rise building fire sprinkler and fire barrier system that, usually during a fire, a threshold value needs to be set for the smoke generated. In order to avoid misjudgment, the alarm can only be triggered when the sensor reaches a certain detection amount. In the actual process, if the threshold value is reached, the thick smoke needs to actively move to the sensor position and reach the threshold value before the alarm can be activated. This process undoubtedly increases the system detection and response time. When a fire occurs, a slow response of the fire extinguishing system may cause greater losses. Therefore, this passive monitoring method cannot meet the needs of rapid response to fires. In view of the shortcomings of the prior art, the present invention provides a high-rise building fire sprinkler and fire barrier system to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a high-rise building fire sprinkler and fire barrier system. Through the design of the booster mechanism, the booster mechanism can be easily activated when the smoke sensor body detects the smoke content and the smoke content has not reached the set threshold, thereby increasing the air flow rate. Therefore, the nearby air is pressurized and actively inhaled after the smoke is sensed. The alarm can be triggered as soon as the smoke increases, shortening the alarm time and improving the sensitivity of the smoke sensor body, thus saving every second for rescue and fire isolation and winning precious time.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-rise building fire sprinkler and fire barrier system, including a water source, a water supply pipeline, a control device, a sprinkler head and a fireproof material, the water supply pipeline connects the water source and the sprinkler head, the control device is arranged on the water supply pipeline, the fireproof material is arranged at the fireproof barrier position of the building wall, and the control device includes a smoke detector, an alarm valve group, a water flow indicator and a signal valve; The water flow indicator and signal valve are arranged in the water supply pipeline, and the smoke detector and alarm valve group are arranged on the top of the building walkway; The smoke detector comprises a bracket arranged on a wall and a base fixedly connected to the bracket, a loading plate is arranged at the bottom of the base, a protective cover is arranged at the bottom of the loading plate, and a smoke sensor body is arranged inside the protective cover; A supercharging mechanism is arranged inside the protective cover, and the supercharging mechanism comprises a supercharging shaft rotatably connected inside the protective cover, a driving component for driving the supercharging shaft, and a turbine arranged on the supercharging shaft.

[0007] Preferably, the turntable is provided with a plurality of groups of air holes.

[0008] Preferably, a first through hole is formed on the base, and a second through hole is formed on the loading plate.

[0009] Preferably, the driving assembly includes a motor fixedly connected to the loading plate and a first pulley fixedly connected to the output end of the motor, a second pulley is connected to the boost shaft, and belts are sleeved on the second pulley and the first pulley.

[0010] Preferably, a bearing plate for providing installation limitation for the smoke sensor body is fixedly connected inside the protective cover.

[0011] Preferably, a docking assembly is provided between the base and the loading plate, the docking assembly comprises a clamping seat arranged on the base and a locking rod arranged on the clamping seat, and a positioning plate is provided on the loading plate, and the positioning plate is movably clamped on the side of the clamping seat.

[0015] The present invention discloses a high-rise building fire sprinkler and fire barrier system, which has the following beneficial effects: 1. The high-rise building fire sprinkler and fire barrier system, through the design of the booster mechanism, makes it easy to start the booster mechanism when the smoke sensor detects the smoke content and the smoke content does not reach the set threshold, thereby increasing the air flow speed. Therefore, the nearby air is actively inhaled after smoke is sensed, and the alarm can be triggered at the first time when the smoke increases, shortening the alarm time and improving the sensitivity of the smoke sensor body, saving every second for rescue and fire isolation, and winning precious time.

[0016] 2. The high-rise building fire sprinkler and fire barrier system, through the design of docking components, makes it easy to disassemble the loading plate, protective cover, smoke sensor body and booster mechanism, so as to facilitate regular inspection and maintenance or replacement and upgrading of the loading plate, protective cover, smoke sensor body and booster mechanism, and ensure good system stability.

[0017] 3. The fire sprinkler and fire barrier system for high-rise buildings realizes the support limit of the turntable through the shaft seat, and then realizes the limit of the boost shaft, ensuring the stability of the boost mechanism. When the turbine rotates to drive the air of the protective cover to be continuously inhaled, it moves upward through the air vent, the second through hole and the first through hole in sequence. After the turbine rotates, a low-pressure area is formed inside the protective cover, and a high-pressure area is formed at the bottom of the protective cover. Therefore, air continuously enters the inside of the protective cover from the bottom of the protective cover and is discharged from the top of the protective cover, thereby increasing the airflow through the main position of the smoke sensor and quickly inhaling nearby air. When smoke occurs, the smoke is quickly inhaled into the main position of the smoke sensor. When a fire occurs, the threshold is quickly reached to alarm, shortening the sensing time.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. 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 are within the scope of protection of the present invention.

[0022] The embodiments of the present application provide a high-rise building fire sprinkler and fire barrier system, which solves the problem that the existing high-rise building fire sprinkler and fire barrier system requires thick smoke to actively move to the sensor position and reach a threshold before an alarm can be activated. This process undoubtedly increases the system detection and response time. When a fire occurs, a fire extinguishing system that is slow to respond by even a second may cause greater losses. Therefore, this passive monitoring method cannot meet the needs of rapid response to fires.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The embodiment of the present invention discloses a high-rise building fire sprinkler and fire barrier system. Figure 1-8 As shown, it includes a water source 1, a water supply pipe 2, a control device 3, a nozzle 4 and a fireproof material 5. The water supply pipe 2 connects the water source 1 and the nozzle 4. The control device 3 is arranged on the water supply pipe 2. The fireproof material 5 is arranged at the fireproof barrier position of the building wall. The control device 3 includes a smoke detector 31, an alarm valve group 32, a water flow indicator 33 and a signal valve 34. The water source 1 is usually a fire water pool or a roof fire water tank, which stores a large amount of clean water to provide the sprinkler system with the water required for fire extinguishing.

[0025] The water supply pipeline 2 connects the water source 1 and the nozzle 4 to ensure that water can be smoothly delivered to each nozzle 4. The water supply pipeline 2 system includes a main pipeline, branch secondary pipelines, branch pipes, etc.

[0026] The control device 3 is the "brain" of the sprinkler system, responsible for monitoring the fire and controlling the water spraying action of the sprinkler head 4. It includes the following parts: The smoke detector 31 is used to monitor the smoke changes at the initial stage of a fire, and once a set threshold is reached, an alarm is triggered.

[0027] The alarm valve group 32, when the sprinkler 4 in the pipe network sprays water, the static balance pressure above and below the valve will be destroyed, the alarm valve will open, an alarm signal will be issued and the fire pump and other facilities will be started.

[0028] The water flow indicator 33 is used to monitor the change of the water flow in the pipeline. When the nozzle 4 sprays water, the water flow indicator 33 will send out an alarm signal.

[0029] The signal valve 34 is used to control the opening and closing of the pipe network and convert the switch signal into an electrical signal to feed back to the automatic fire alarm host.

[0030] Nozzle 4, when a fire occurs, the nozzle 4 will automatically release a water column to extinguish the fire after reaching a certain temperature. There are many types of nozzles 4, such as drooping type, upright type, ordinary type and side wall type, etc., which can be selected according to different places of use.

[0031] In addition, fireproof materials 5 are used in the structure of buildings to improve the fire resistance of buildings and prevent the spread of fire.

[0032] The water flow indicator 33 and the signal valve 34 are arranged in the water supply pipe 2, and the smoke detector 31 and the alarm valve group 32 are arranged on the top of the building walkway; The smoke detector 31 includes a bracket 311 disposed on a wall and a base 312 fixedly connected to the bracket 311. A loading plate 313 is disposed at the bottom of the base 312. A protective cover 314 is disposed at the bottom of the loading plate 313. A smoke sensor body 315 is disposed inside the protective cover 314. The bracket 311 is used to fix the base 312, and the base 312 is used to clamp the loading plate 313, so as to facilitate the support of the protective cover 314 and the smoke sensor body 315, and the smoke sensor body 315 is used to perform smoke detection.

[0033] A boost mechanism 316 is provided inside the protective cover 314, and the boost mechanism 316 includes a boost shaft 3161 rotatably connected to the inside of the protective cover 314, a driving assembly 3165 for driving the boost shaft 3161, and a turbine 3164 arranged on the boost shaft 3161; through the design of the boost mechanism 316, the boost mechanism 316 is easy to start when the smoke sensor body 315 detects the smoke content and the smoke content does not reach the set threshold, thereby increasing the airflow circulation speed. Therefore, the alarm can be triggered at the first time when the smoke increases, shortening the alarm time, and improving the sensitivity of the smoke sensor body 315, saving every second for rescue and fire prevention, and winning precious time.

[0034] The working principle of the boost mechanism 316 is that when smoke is detected and the threshold value is not reached, the boost shaft 3161 is driven to rotate through the driving component 3165, and the boost shaft 3161 drives the turbine 3164 to rotate. After the turbine 3164 rotates, a low-pressure area is formed inside the protective cover 314, and a high-pressure area is formed at the bottom of the protective cover 314. Therefore, air continuously enters the interior of the protective cover 314 from the bottom of the protective cover 314 and is discharged from the top of the protective cover 314, thereby increasing the airflow through the position of the smoke sensor body 315 and quickly inhaling nearby air. When smoke occurs, the smoke is quickly inhaled into the position of the smoke sensor body 315. When a fire occurs, the threshold is quickly reached to alarm, thereby shortening the sensing time.

[0035] The boost mechanism 316 also includes a turntable 3162 fixedly connected to the boost shaft 3161 and a shaft seat 3163 fixedly connected to the inside of the protective cover 314. The turntable 3162 is rotatably connected in the shaft seat 3163. The device supports and limits the turntable 3162 through the shaft seat 3163, thereby providing a limit for the boost shaft 3161, thereby ensuring good stability of the boost mechanism 316.

[0036] The turntable 3162 is provided with a plurality of air vents 31621, the base 312 is provided with a first through hole 3121, and the loading plate 313 is provided with a second through hole 3133; when the turbine 3164 rotates and drives the air of the protective cover 314 to be continuously sucked in, the air moves upward through the air vents 31621, the second through hole 3133 and the first through hole 3121 in sequence.

[0037] The driving assembly 3165 includes a motor 31651 fixedly connected to the loading plate 313 and a first pulley 31652 fixedly connected to the output end of the motor 31651. The boost shaft 3161 is connected to a second pulley 31653. The second pulley 31653 and the first pulley 31652 are sleeved with a belt 31654. The driving assembly 3165 in the device has a compact structure and is easy to use. The driving assembly 3165 is powered by the motor 31651. The motor 31651 drives the first pulley 31652 to rotate. The first pulley 31652 drives the belt 31654 to rotate. The belt 31654 drives the second pulley 31653 to rotate. The second pulley 31653 drives the boost shaft 3161 to rotate.

[0038] A support plate 3151 for providing installation limit for the smoke sensor body 315 is fixedly connected inside the protective cover 314. The design of the support plate 3151 makes it easy to install and fix the smoke sensor body 315, and the protective cover 314 is used to provide protection for the support plate 3151.

[0039] A docking assembly 317 is provided between the base 312 and the loading plate 313. The docking assembly 317 includes a base 3171 provided on the base 312 and a locking rod 3174 provided on the base 3171. A positioning plate 3131 is provided on the loading plate 313. The positioning plate 3131 is movably connected to the side of the base 3171. A plug hole 3132 is provided on the positioning plate 3131. The locking rod 3174 is movably connected to the plug hole 3132. A spring 3172 is provided inside the base 3171. Both ends of the spring 3172 are fixedly connected to sliders 3173. The slider 3173 is slidably connected to the inside of the base 3171. The locking rod 3174 is fixedly connected to the slider 3173. A push handle is provided on the side of the slider 3173. The device is designed with a docking assembly 317, so that the loading plate 313, the protective cover 314, the smoke sensor body 315 and the boost mechanism 316 are easy to disassemble, so that the loading plate 313, the protective cover 314, the smoke sensor body 315 and the boost mechanism 316 are convenient to be repaired, maintained or replaced and upgraded, thereby ensuring good system stability; When it is necessary to install the loading plate 313, the protective cover 314, the smoke sensor body 315 and the boost mechanism 316 to the target position, first pull the push handle of the slider 3173 so that the slider 3173 drives the locking rod 3174 to move and squeeze the spring 3172. At this time, align and engage the loading plate 313 with the base 312. At the same time, engage the base 3171 with the positioning plate 3131. After they are fully engaged, release the push handle of the slider 3173 so that the spring 3172 is reset and pushes the slider 3173 and the locking rod 3174 to move, so that the locking rod 3174 is inserted into the socket 3132, thereby locking the positioning plate 3131, the loading plate 313, the protective cover 314, the smoke sensor body 315 and the boost mechanism 316.

[0040] When it is necessary to disassemble the loading plate 313, the protective cover 314, the smoke sensor body 315 and the boost mechanism 316, the above installation process can be reversed to achieve rapid disassembly.
