Description

Technical Field

[0001] The present invention relates to the technical field of automatic fire warning, and in particular to an integrated device and method for automatically warning fires in venue buildings. Background Art

[0002] The venue building fire automatic early warning construction integrated device is a system that integrates multiple sensors and intelligent analysis algorithms.

[0012] The present invention also discloses a method for using a venue building fire automatic early warning construction integrated device, comprising the following steps:

[0013] Step 1: When installing the automatic fire warning construction integrated device in the venue building, first fix the mounting base in the designated area with screws. Then, the operator rotates the rotating knob to make the shaft drive the second gear to rotate, and then mesh with the third gear for transmission. As the third gear rotates, the threaded rod is driven to rotate at the same time. Since the two threaded plates are connected to the threaded rod by threads, as the threaded rod rotates, the two threaded plates move relative to each other, and the two threaded plates drive the two clamping plates at the bottom to move relative to each other. At this time, the operator continues to turn the rotating knob to make the two clamping plates drive the driving blocks to be stuck in the slots on the connecting blocks on both sides of the shell to complete the installation.

[0014] Step 2: When external air enters the shell through the filter and is detected in real time by the smoke sensor and gas sensor, when the smoke or specific gas concentration detected exceeds the preset threshold, the smoke sensor and gas sensor will send a signal to the communication module. After receiving the signal, the communication module will transmit the fire warning information to the fire center or other relevant departments through the preset communication protocol. At the same time, after receiving the signal, the linkage control module will start the fire-fighting equipment connected to the fire warning device, such as the automatic sprinkler fire extinguishing system, the smoke exhaust system, etc., to control the spread of fire and ensure the safe evacuation of personnel.

[0015] Step three: to prevent a large amount of dust from adhering to the filter and causing blocked air intake after long-term use, which would affect the detection effect, the motor drives the first gear to engage the gear ring to rotate the air intake hood, and the air intake hood drives the filter to rotate. Since the soft brush is in contact with the filter, the dust attached to the surface of the filter can be swept off when the filter rotates, thereby preventing the filter from being blocked and maintaining its good filtering performance, ensuring that the early warning device can accurately and timely detect fires.

[0016] Compared with the prior art, the beneficial effects of the present invention include:

[0017] The automatic early warning construction integrated device for venue building fire of the present invention comprises a mounting seat, a rotating column, a second gear, a third gear, a threaded rod, a threaded plate, a clamping plate, a connecting block, a slot, a clamping block and a rotating button. An operator can drive the threaded rod to rotate by engaging the second gear with the second gear by rotating the rotating button. As the threaded rod rotates, the two threaded plates will move horizontally relative to or opposite to each other, thereby driving the clamping block on the clamping plate to be tightly combined with or separated from the slot. The present invention not only simplifies the steps of installation and disassembly, avoids the cumbersomeness brought by the traditional screw fixing method, but also reduces the required operating tools, greatly improving the work efficiency. The scheme of the air intake hood, the filter screen, the gear ring, the motor, the first gear, the connecting rod and the soft brush, the motor drives the first gear to engage the gear ring to rotate, thereby driving the filter screen on the air intake hood to rotate. During the rotation of the filter screen, the soft brush can clean the dust filtered on the surface of the filter screen, avoiding the performance degradation of the device caused by the clogging of the filter screen, and greatly reducing the frequency and difficulty of manual maintenance, improving the service life and stability of the device, and providing more reliable protection for the fire safety of the venue building.

[0033] An integrated device for automatically warning the construction of a venue building fire includes the following steps:

[0034] Step 1, when installing the fire automatic warning construction integrated device in the venue building, first fix the mounting base 1 in the designated area with screws, then the operator rotates the rotating knob 26, so that the shaft 15 drives the second gear 14 to rotate, and then meshes with the third gear 16 for transmission. As the third gear 16 rotates, the threaded rod 17 is driven to rotate at the same time. Since the two threaded plates 18 are connected to the threaded rod 17 by threads, as the threaded rod 17 rotates, the two threaded plates 18 move relative to each other, and the two threaded plates 18 drive the two clamping plates 20 at the bottom to move relative to each other.

[0035] Step 2. When external air enters the shell 2 through the filter 4 and is detected in real time by the smoke sensor 27 and the gas sensor 28, when the smoke or specific gas concentration detected exceeds the preset threshold, the smoke sensor 27 and the gas sensor 28 will send a signal to the communication module. After receiving the signal, the communication module will transmit the fire warning information to the fire center or other relevant departments through the preset communication protocol. At the same time, after receiving the signal, the linkage control module will start the fire-fighting equipment connected to the fire warning device, such as the automatic sprinkler fire extinguishing system, the smoke exhaust system, etc., to control the spread of fire and ensure the safe evacuation of personnel.

[0036] Step three, in order to prevent a large amount of dust from adhering to the filter 4 and causing blocked air intake after long-term use, which affects the detection effect, the motor 6 drives the first gear 7 to engage the gear ring 5 to rotate the air intake hood 3, and the air intake hood 3 drives the filter 4 to rotate. Since the soft brush 10 is in contact with the filter 4, the soft brush 10 can sweep off the dust attached to the surface of the filter 4 when the filter 4 rotates, thereby preventing the filter 4 from being blocked, maintaining its good filtering performance, and ensuring that the early warning device can accurately and timely detect fires.

Then, the operator rotates the rotating knob (26) so that the shaft (15) drives the second gear (14) to rotate, and then meshes with the third gear (16). As the third gear (16) rotates, the threaded rod (17) is driven to rotate at the same time. Since the two threaded plates (18) are connected to the threaded rod (17) by threads, as the threaded rod (17) rotates, the two threaded plates (18) move relative to each other, and the two threaded plates (18) drive the two clamping plates (20) at the bottom to move relative to each other.
