Description

Technical Field

[0001] The invention belongs to the technical field of fire safety, and in particular relates to a fire remote alarm device. Background Art

[0002] Fire remote alarm device is the basic terminal equipment of fire protection system. When the smoke concentration in the air reaches a certain level due to fire, the fire remote alarm device will give an alarm in time, effectively ensuring that the alarm is given at the early stage of the fire and reducing the losses caused by the fire. With the development of my country's economy, the attention to fire safety has also increased, so the fire remote alarm device has also been widely used. However, in the existing technology, the fire remote alarm device still has the following problems when used:

[0003] 1. In the prior art, when there is no fire, the light emitted by the infrared light source in the sensing box of the fire remote alarm device will hit the maze board, but will not hit the photodiode, so that the alarm module will not alarm. When a fire occurs and a large amount of smoke is generated, the smoke will enter the sensing box, and the smoke particles will scatter or refract the light emitted by the infrared light source, so that the light will hit the photodiode, and then the alarm module will work to remotely alarm. However, since the fire remote alarm device is installed at a high position and the structure inside the sensing box is complex and not easy to clean, dust is easily accumulated in the sensing box after a long period of work, and the dust particles will affect the light emitted by the infrared light source inside the sensing box, causing the fire remote alarm device to falsely alarm.

[0004] 2. At present, fire remote alarm devices generally use batteries as power sources. Therefore, in order to ensure that the fire remote alarm devices can be effective at all times, workers are required to replace the batteries regularly. However, existing fire remote alarm devices are usually installed on the ceiling for use, and replacing the batteries requires disassembling the shell of the fire remote alarm device, which requires a lot of manpower to replace the batteries.

[0048] See also Figure 1 , Fig.12 When the locking pin 51 extends into the locking groove 131, the housing 1 is in a closed state; when the locking pin 51 withdraws from the locking groove 131, the housing 1 is in an open state.

[0049] See also Figure 1-Figure 3 , Figure 7 The circuit board, the alarm module, the infrared light source and the photodiode are all arranged in the housing 12.

[0050] The working principle of this fire remote alarm device is as follows:

[0051] like Figure 1 The internal structure of the present invention is shown. When there is no fire in the area monitored by the present invention, the light emitted by the infrared light source will always shine on the labyrinth plate 212. Through the reflection of the labyrinth plate 212, the light will not shine on the photodiode, so that the alarm module will not alarm. When a fire occurs in the area monitored by the present invention and a large amount of smoke is generated, after the smoke enters the sensing box 21, the smoke particles scatter or refract the light emitted by the infrared light source, so that the light shines on the photodiode, and then the alarm module works to remotely alarm, thereby realizing remote monitoring of the fire.

[0052] When the present invention is used for a long time and the dust in the induction box 21 needs to be simply cleaned, the housing 12 is first driven to rotate forward. Since the transmission rod 122 and the linkage slider 32 are matched through the flat key, and the linkage pin 311 and the linkage slider 32 are slidably matched, one end of the linkage push rod 33 is hinged to the linkage slider 32, and the other end is hinged to the battery box body 41. The battery box spring 42 drives the battery box body 41 to move upward, so that when the housing 21 drives the linkage slider 32 to rotate, the linkage slider 32 drives the linkage pin 311 to be close to the periphery of the control disk 61, and then drives the linkage pin 311 to rotate clockwise around the control disk 61 ( Fig.10 ), as the linkage pin 311 rotates, the linkage pin 311 and the control boss 611 touch each other, and under the action of the boss inclined surface 612, the linkage pin 311 is pushed to move downward, so that the linkage push plate 31 pushes the lifting slide plate 34 to descend, and then pushes the induction box 21 to overcome the induction spring 25 and move downward, so that the rubber bellows 22 is compressed, and the air in the rubber bellows 22 enters the blowing channel 211 through the first one-way valve 231, and then blows into the inside of the induction box 21 through the air hole 213, and blows on the labyrinth plate 212 at the same time, so that the dust in the induction box 21 and the dust hanging on the labyrinth plate 212 are blown out to the outside, and when the linkage pin 311 passes over the control boss 611, the induction box 21 is pushed up under the action of the induction spring 25, and the linkage push plate 31 is pushed up through the lifting slide plate 34, so that the linkage pin The upper end of 311 is pressed against the shell seat 11 again. As the induction box 21 rises, the rubber bellows 22 expands, and external air enters the rubber bellows 22 through the second one-way valve 232. As the linkage pin 311 rotates, when the linkage pin 311 contacts the first control side plate 621, the linkage pin 311 overcomes the control torsion spring 63 to push the first control side plate 621 to rotate. When the linkage pin 311 passes over the first control side plate 621, the control plate 62 is driven to rotate under the action of the control torsion spring 63, so that the first control side plate 621 and the control plate 61 are in close contact, so that the linkage pin 311 completes one circle of rotation. By continuously rotating the shell 12, the induction box 21 can be driven to move back and forth for multiple times, so that the air in the rubber bellows 22 is continuously blown into the induction box 21, so that the dust entering the induction box 21 can be cleaned;

[0053] When the present invention is used for a long time and needs to be thoroughly maintained, the housing 12 is first reversed to drive the linkage pin 311 to rotate counterclockwise around the control disk 61. As the linkage pin 311 rotates, when the linkage pin 311 touches the first inclined surface 624, the first inclined surface 624 pushes the linkage pin 311, driving the linkage slider 32 to move along the transmission rod 122 away from the control disk 61, and the battery box 41 is driven to move downward through the housing window 121 through the linkage push rod 33. Since the swing frame baffle 431 is in contact with the housing 12, the limit torsion spring 45 is overcome to drive the limit The swing frame 43 rotates; as the linkage pin 311 rotates, the linkage pin 311 contacts the first arc surface 625, the limit swing frame 43 opens, and the battery falls on the limit roller 44 under the action of gravity; as the linkage pin 311 rotates, the linkage pin 311 contacts the second inclined surface 626, and the second inclined surface 626 pushes the linkage pin 311 to continue to move away from the control disk 61, thereby driving the battery box body 41 to continue to descend; as the linkage pin 311 rotates, the linkage pin 311 contacts the second arc surface 627, and the battery box body 41 descends, so that the limit swing frame 43 opens to Figure 6When the second control side plate 622 and the control boss 611 are in contact, the control board 62 cannot continue to rotate, preventing the linkage pin 311 from continuing to rotate, thereby causing the battery box 41 to drop to the lowest end, so that the box body push plate 411 pushes the unlocking lever 52 to rotate. When the unlocking lever 52 rotates, the linkage pin 311 is pushed away from the control panel 61, thereby driving the battery box body 41 to continue to descend, and the swing frame baffle 431 and the shell 12 remain in contact. The locking push rod 512 drives the locking pin 51 to overcome the locking spring 53 and move, so that the locking pin 51 exits the locking groove 131, so that the flip cover 13 is unlocked and flipped, releasing the sensing mechanism 2, so that the sensing mechanism 2 can be quickly removed. When the sensing mechanism 2 is removed, the shell 12 is driven to rotate forward, so that the linkage pin 311 returns to contact with the first arc surface 625, so that the battery box body 41 rises, and the limiting swing frame 43 is driven to swing to the middle under the action of the limiting torsion spring 45, and then a new battery is inserted into the battery box body 41, so that the battery and the limiting roller 44 contact, and then the limiting swing frame 43 is pushed by the limiting roller 44 to overcome the limiting torsion spring 45 and rotate. When the battery enters the battery box body 41 and is higher than the limiting roller 44, the limiting swing frame 43 rotates to the middle under the action of the limiting torsion spring 45, and the battery is limited in the battery box body 41, and then the shell 12 is controlled to rotate forward, so that the linkage pin 311 returns to contact with the control disk 61. The battery box body 41 rises and resets, and under the action of the limiting torsion spring 45, the limiting swing frame 43 is driven to rotate, and the battery is pushed completely into the battery box body 41 through the limiting roller 44, so that the battery and the positive and negative electrodes 412 are connected, and the battery installation is completed; after the induction box 21 is cleaned, the induction mechanism 2 is put back, and the flip cover 13 is rotated, and the locking pin 51 overcomes the locking spring 53 through the locking inclined surface 511 to move, and when the locking pin 51 enters the locking groove 131, the maintenance is completed.

[0054] The staff can use a long-handled tool on the ground, insert the tool into the housing slot 123, and then rotate the long-handled tool to drive the housing 12 to rotate, or the staff can also rotate the housing 12 manually, making the rotation of the housing 12 more convenient.

[0055] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
