Description

Technical Field

[0001] This utility model relates to the field of building fire alarm technology, specifically a building fire safety alarm device. Background Technology

[0002] Building fire alarm systems are important safety facilities used to promptly warn people to evacuate dangerous areas in the event of a fire and to activate the fire suppression system to respond to the fire. They can quickly identify fire signs through smoke detectors and provide an alarm before the fire spreads, allowing evacuation and response measures to begin as early as possible, greatly reducing the risk of casualties and property damage. They alert people in the building by issuing audible and visual alarms and may include automatic voice evacuation instructions to guide people to evacuate safely and orderly to safe locations, avoiding secondary injuries caused by panic.

[0003] Currently, smoke detectors are commonly used in buildings for fire monitoring and alarm functions. Maintaining the cleanliness and accessibility of these detectors is crucial for daily maintenance. Regularly using a vacuum cleaner or soft brush to remove dust and debris is necessary. However, smoke detectors are typically installed on the roof of a building, making daily maintenance extremely inconvenient. Therefore, we offer building fire safety alarm devices to address these issues. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a building fire safety alarm device.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a building fire safety alarm device, comprising a receiving basket, the receiving basket having a receiving cavity, the receiving basket having a first through hole, a roller mechanism being provided inside the receiving basket, an installation mechanism being provided outside the receiving basket, a smoke detector body being installed below the receiving basket, the smoke detector body having a through groove, and a clamping mechanism being provided inside the through groove.

[0008] Furthermore, the reel mechanism includes a first support plate, the first support plate having a second through hole, a servo motor mounted on the first support plate, a rotating rod fixedly connected to the output end of the servo motor, and the rotating rod rotatably connected to the second support plate.

[0009] Furthermore, the second support plate is fixedly connected to the receiving basket, and the rotating rod is fixedly connected to a connecting rope. The end of the connecting rope away from the rotating rod passes through the first through hole and extends into the interior of the clamping mechanism.

[0010] Furthermore, the clamping mechanism includes a first fixing block and a second fixing block, wherein the first fixing block is fixedly connected to the through groove and the second fixing block is fixedly connected to the receiving basket.

[0011] Furthermore, the second fixing block has a threaded hole, and a second screw is installed inside the threaded hole.

[0012] Furthermore, the installation mechanism includes a fixing ring and a plurality of first screws. The fixing ring is fixedly connected to the receiving basket. The fixing ring has a plurality of third through holes and a gasket is fixedly connected to the fixing ring.

[0013] Furthermore, the gasket has multiple fourth through holes, and the output ends of the multiple first screws pass through the third and fourth through holes in sequence.

[0014] (iii) Beneficial effects:

[0015] Compared with existing technologies, this building fire safety alarm device has the following advantages:

[0016] I. This utility model controls a servo motor to rotate counterclockwise, which in turn drives a rotating rod to rotate counterclockwise. Under the weight of the smoke detector, the connecting rope wrapped around the rotating rod can be pulled downwards, thus moving the smoke detector from the top of the building down to a height accessible to ground personnel. After maintenance, the operator controls the servo motor to rotate clockwise, simultaneously driving the rotating rod to rotate clockwise, allowing the connecting rope to be wound around the rotating rod, thereby restoring the smoke detector to its original position. This solves the problem of smoke detectors being inconvenient to maintain when installed on the top of buildings, and makes daily maintenance of this device convenient.

[0017] II. This utility model, by setting up a clamping mechanism, allows for the control of the second screw to spirally move away from the first fixing block when the smoke detector body is damaged and needs to be replaced. This releases the connecting rope from the clamping mechanism, allowing for the replacement of the smoke detector body. The end of the connecting rope away from the rotating rod is placed at the center position between the first and second fixing blocks. The second screw is then spirally moved towards the end closer to the first fixing block, thus securing the connecting rope between the first fixing block and the output end of the second screw. This achieves the purpose of quickly replacing the smoke detector. By placing the device in the installation position, marking the drilling point at the third through hole, and then drilling the installation hole at the marked point, the first screw is controlled to pass through the third and fourth through holes and is threaded into the interior of the installation hole, achieving the purpose of quick installation of the device.

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.

[0025] like Figure 1-5 This utility model provides a technical solution: a building fire safety alarm device, including a receiving basket 1, a receiving cavity 2, a first through hole 3, and a winding mechanism 4 inside the receiving basket 1. The winding mechanism 4 includes a first support plate 401, a second through hole 402, a servo motor 403 mounted on the first support plate 401, a rotating rod 404 fixedly connected to the output end of the servo motor 403, a second support plate 405 rotatably connected to the rotating rod 404, the second support plate 405 being fixedly connected to the receiving basket 1, and a connecting rope 406 fixedly connected to the rotating rod 404. The end of the connecting rope 406 away from the rotating rod 404 passes through the first through hole 3 and extends into the interior of the clamping mechanism 8.

[0026] The first through hole 3 here has rounded edges to prevent cutting the connecting rope 406. The servo motor 403 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources. The material of the connecting rope 406 is preferably steel wire rope. By controlling the servo motor 403 to rotate counterclockwise, the rotating rod 404 is driven to rotate counterclockwise. Under the gravity of the smoke detector body 6, the connecting rope 406 wrapped on the rotating rod 404 can be pulled downward, thereby moving the smoke detector body 6 from the top of the building down to a height that can be operated by personnel on the ground. After the operator maintains the smoke detector body 6, by controlling the servo motor 403 to rotate clockwise, the rotating rod 404 is driven to rotate clockwise, and the connecting rope 406 can be wrapped around the rotating rod 404, thereby restoring the smoke detector body 6 to its original position, realizing the convenience of daily maintenance of this device.

[0027] The container basket 1 is provided with an installation mechanism 5. The installation mechanism 5 includes a fixing ring 501 and multiple first screws 505. The fixing ring 501 is fixedly connected to the container basket 1. The fixing ring 501 has multiple third through holes 502. The fixing ring 501 is fixedly connected to a gasket 503. The gasket 503 has multiple fourth through holes 504. The output ends of the multiple first screws 505 pass through the third through holes 502 and the fourth through holes 504 in sequence.

[0028] The material of the gasket 503 is preferably rubber. The diameter of the third through hole 502 is the same as that of the fourth through hole 504, and they are aligned vertically. The first screw 505 is existing technology and will not be described in detail. By placing the device in the installation position, marking the drilling point at the third through hole 502, and then opening the installation hole at the marked point, the first screw 505 is controlled to pass through the third through hole 502 and the fourth through hole 504, and the thread is connected to the inside of the installation hole, the purpose of quick installation of the device is achieved.

[0029] A smoke detector body 6 is installed below the receiving basket 1. The smoke detector body 6 has a through groove 7. A clamping mechanism 8 is provided inside the through groove 7. The clamping mechanism 8 includes a first fixing block 801 and a second fixing block 802. The first fixing block 801 is fixedly connected to the through groove 7, and the second fixing block 802 is fixedly connected to the receiving basket 1. The second fixing block 802 has a threaded hole 803, and a second screw 804 is installed inside the threaded hole 803.

[0030] The position where the first fixing block 801 and the output end of the second screw 804 press against the connecting rope 406 is the center position of the smoke detector body 6. The second screw 804 is existing technology and will not be described in detail. By controlling the second screw 804 to spirally move away from the first fixing block 801, the connecting rope 406 is released from clamping. Then, when replacing the smoke detector body 6, the end of the connecting rope 406 away from the rotating rod 404 is placed at the center position between the first fixing block 801 and the second fixing block 802. By controlling the second screw 804 to spirally move towards the end closer to the first fixing block 801, the connecting rope 406 can be attached between the first fixing block 801 and the output end of the second screw 804, thus achieving the purpose of quickly replacing the smoke detector alarm.

[0031] Working Principle: When using this device, by controlling the servo motor 403 to rotate counterclockwise, the rotating rod 404 is driven to rotate counterclockwise. Under the gravity of the smoke detector body 6, the connecting rope 406 wrapped around the rotating rod 404 can be pulled downwards, thereby moving the smoke detector body 6 from the top of the building down to a height accessible to ground personnel. After maintenance of the smoke detector body 6, by controlling the servo motor 403 to rotate clockwise, the rotating rod 404 is driven to rotate clockwise, allowing the connecting rope 406 to be wound around the rotating rod 404, thus restoring the smoke detector body 6 to its original position. This facilitates convenient daily maintenance of the device. When the smoke detector body 6 is damaged and needs replacement, the second screw 804 is controlled to spirally move away from the first fixing block 801, thereby... Release the clamping fixation of the connecting rope 406, and then replace the smoke detector body 6. Place the end of the connecting rope 406 away from the rotating rod 404 at the center position between the first fixing block 801 and the second fixing block 802. Control the second screw 804 to spirally move towards the end closer to the first fixing block 801, thereby attaching the connecting rope 406 between the first fixing block 801 and the output end of the second screw 804. This achieves the purpose of quickly replacing the smoke detector. When installing this device, place the device in the installation position, mark the drilling point at the third through hole 502, and then open the installation hole at the marked point. Control the first screw 505 to pass through the third through hole 502 and the fourth through hole 504, and thread it into the inside of the installation hole. This achieves the purpose of quickly installing this device.
