Technical Field
[0001] This utility model relates to the field of emergency evacuation technology, specifically a fire emergency evacuation alarm device. Background Technology
[0002] A fire emergency evacuation alarm device is a device used to evacuate people and remind them to take safety measures in emergency situations. It is usually combined with a fire detection system and can quickly issue an alarm in emergencies such as fires to ensure that people can evacuate in a timely manner.
[0003] Most existing fire emergency evacuation alarm devices are installed in the corners of corridors or passageways, and mostly only serve as alarm bells to warn and remind people. After a fire breaks out, people are already in a panic during the evacuation process, and the presence of thick smoke makes it difficult for them to find the safety passage routes posted on the walls, causing them to run around randomly and go to the wrong places, delaying the best escape time and threatening people's lives and property.
[0004] Therefore, existing fire emergency evacuation alarm devices have the problem of limited functionality, only alerting people to the occurrence of a fire but not indicating how to evacuate correctly. Thus, a fire emergency evacuation alarm device is proposed to solve the above problems. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, this utility model provides a fire emergency evacuation alarm device, which solves the problems mentioned in the background technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire emergency evacuation alarm device, comprising a mounting plate, an alarm mounted on the mounting plate, a smoke sensor mounted on the top of the mounting plate, a button mounted on one end of the alarm, the button being electrically connected to the alarm, an electric push rod mounted above the button, the smoke sensor being electrically connected to the electric push rod, a wedge plate mounted at the output end of the electric push rod, an L-shaped push plate mounted on the top of the button, pressure rods slidably mounted on both sides of the mounting plate, the pressure rods contacting the L-shaped push plates, a winding drum mounted below the mounting plate, four sets of support plates rotatably mounted at both ends of the winding drum, each pair of support plates being symmetrically arranged in a V-shape on both sides of the winding drum, the top of the support plates contacting the pressure rods, an opening at the bottom of the winding drum, an mounting rod below the winding drum, a clamping plate mounted on one side of the mounting rod, one end of the clamping plate being rotatably inserted into the interior of the mounting rod, a torsion spring B being mounted between the mounting rod and the clamping plate, the two ends of the torsion spring B being connected to the mounting rod and the clamping plate respectively.
[0007] Preferably, a push rod is provided below the button, and a mounting bracket is provided below the mounting plate. The push rod is slidably mounted on the mounting bracket, and an inclined plate is provided at the top of the push rod. The axis of the push rod coincides with that of the electric push rod.
[0008] Preferably, the moving direction of the L-shaped push plate is perpendicular to the moving direction of the pressure rod.
[0009] Preferably, the bottom of the pressure rod is in the shape of an "8", and the bottom of the pressure rod is always in contact with the support plate.
[0010] Preferably, a torsion spring A is provided between the pallet and the winding drum.
[0011] Preferably, a counterweight is slidably disposed on the mounting rod and the clamping plate.
[0012] Preferably, the axis of the rotation center of the clamping plate coincides with the axis of the mounting rod.
[0013] Preferably, the mounting plate has multiple mounting holes.
[0014] This utility model provides a fire emergency evacuation alarm device. It has the following beneficial effects:
[0015] 1. This fire emergency evacuation alarm device features an installation plate with an alarm unit mounted on it. A smoke sensor is located at the top of the installation plate. A button is slidably embedded in one end of the alarm unit and is electrically connected to the alarm. Above the button is an electric push rod. Pressing the button with the electric push rod powers the alarm and triggers it. The smoke sensor is electrically connected to the electric push rod. A wedge plate is located at the output end of the electric push rod. When the smoke sensor detects a fire signal, it transmits an electrical signal to the electric push rod, which then pushes out, causing the wedge plate to press the button. An L-shaped push plate is located at the top of the button. This L-shaped push plate moves a pressure rod, causing the pressure rod to move downwards and rotate a support plate. The installation rod then causes an escape route map to automatically drop and unfold, allowing people to find a reasonable escape route by following the alarm sound, thus reducing casualties caused by fire.
[0016] 2. This fire emergency evacuation alarm device is mounted on a mounting plate by means of a push rod. The top of the push rod has an inclined plate, and the axis of the push rod coincides with that of the electric push rod. When it is necessary to open the escape route map, the push rod can be pushed upwards. The inclined plate at the top of the push rod presses the button, causing the L-shaped push plate and the pressure rod to move, opening the support plate and lowering the mounting rod. This provides another way to open the support plate, so that the escape route map can be manually unfolded in routine maintenance or emergency situations.
[0017] 3. The fire emergency evacuation alarm device has a counterweight block that slides on the mounting rod and clamp plate. The counterweight block can be shaped to match the mounting rod and clamp plate, ensuring that the counterweight block can slide from one end of the mounting rod and fit onto its outside, while also providing additional gravity to the mounting block to help the escape route map fall and unfold smoothly.

[0025] 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.
[0026] This utility model embodiment provides a fire emergency evacuation alarm device, such as Figure 1-6As shown, the device includes a mounting plate 1, on which an alarm 2 is mounted. The alarm 2 can be a ringing type. A smoke sensor 6, model LG-GDYG, is mounted on the top of the mounting plate 1. A button 3 is slidably embedded at one end of the alarm 2 and is electrically connected to the alarm 2. An electric push rod 4 is located above the button 3. Pressing the button 3 under the action of the electric push rod 4 will power on the alarm 2 and trigger the ringing alarm. The smoke sensor 6 is electrically connected to the electric push rod 4. The electric push rod 4... A wedge plate 5 is provided at the outlet. When the smoke sensor 6 detects a fire signal, it transmits an electrical signal to the electric push rod 4. The electric push rod 4 extends, causing the wedge plate 5 to press the button 3. An L-shaped push plate 8 is provided at the top of the button 3. The L-shaped push plate 8 can move synchronously with the button 3. Pressure rods 9 are slidably provided on both sides of the mounting plate 1. The pressure rods 9 are in contact with the L-shaped push plates 8. A winding drum 7 is provided below the mounting plate 1. The winding drum 7 is used to hold rolled-up escape route maps and other indicative drawings or maps, hereinafter collectively referred to as... The escape route diagram features four sets of support plates 10 rotatably mounted at both ends of the winding drum 7. Each pair of support plates 10 is symmetrically arranged in a V-shape on both sides of the winding drum 7. The top of each support plate 10 contacts the pressure rod 9. A mounting rod 12 is located below the winding drum 7, with a clamping plate 13 on one side. When the two sets of support plates 10 are in contact, they can wrap around the mounting rod 12 to prevent it from falling. One end of the clamping plate 13 is rotatably inserted into the interior of the mounting rod 12. The lower end of the winding drum 7 has an opening, allowing the lower end of the escape route diagram to extend out. The drum 7 is connected and fixed to the mounting rod 12 and the clamping plate 13. The axis of the winding drum 7 can also be set with a rotating shaft. The wound escape route map is slidably inserted into the rotating shaft of the axis of the winding drum 7, so that the escape route map can be rotated and opened in the winding drum 7. A torsion spring B14 is set between the mounting rod 12 and the clamping plate 13. The two ends of the torsion spring B14 are connected to the mounting rod 12 and the clamping plate 13 respectively. The torque of the torsion spring B14 can keep the clamping plate 13 clamped to the mounting rod 12 at all times, which is used to hold the lower end of the escape route map and assist the escape map to be opened smoothly.
[0027] A push rod 16 is located below button 3, and a mounting bracket 15 is located below mounting plate 1. The push rod 16 is slidably mounted on the mounting bracket 15. A spring A17 is installed between the push rod 16 and the mounting bracket 15, which assists the push rod 16 in automatically resetting. A ramp is provided at the top of the push rod 16, and the axis of the push rod 16 coincides with that of the electric push rod 4. When it is necessary to open the escape route map, the push rod 16 can be pushed upwards. The push rod 16 moves the ramp upwards, pressing button 3. The L-shaped push plate 8 moves in the direction of button 3, pressing the pressure rod 9 downwards. The bottom of the pressure rod 9 is V-shaped and always in contact with the support plate 10. The downward movement of the pressure rod 9 opens the two sets of V-shaped support plates 10, and the mounting rod 12 falls, extending the escape route map. A torsion spring A11 is provided between the support plate 10 and the winding drum 7. The torsion spring A11 ensures that there is always torque between the support plate 10 and the winding drum 7 when the button 3, smoke sensor 6, and alarm 2 are not working. This torque keeps the two sets of support plates 10 in contact at the bottom, preventing the mounting rod 12 from falling. The axis of rotation of the clamping plate 13 coincides with the axis of the mounting rod 12, allowing the clamping plate 13 to rotate and adhere tightly to the mounting rod 12 under the action of the torsion spring B14. The moving direction of the L-shaped push plate 8 is perpendicular to the moving direction of the pressure rod 9, so that when the L-shaped push plate 8 moves laterally, it can drive the pressure rod 9 to move vertically. A counterweight 121 is slidably mounted on the mounting rod 12 and clamping plate 13. The counterweight 121 can be a shape adapted to the mounting rod 12 and clamping plate 13, ensuring that the counterweight 121 can slide onto the outside of the mounting rod 12 from one end, while also providing additional gravity to the mounting rod 12 to assist in the smooth unfolding of the escape route map. Multiple mounting holes are provided on the mounting plate 1 for easy and secure installation of the fire emergency evacuation alarm device on the wall.
[0028] Working principle: In use, the rolled-up escape route map is placed into the winding drum 7, and the end of the escape route map extends from the opening at the bottom of the winding drum 7 and connects to the mounting rod 12. The torque of the torsion spring B14 ensures that the clamping plate 13 is always clamped to the mounting rod 12 to hold the lower end of the escape route map. When a fire occurs, the smoke sensor 6 detects the smoke signal and activates the electric push rod 4. The electric push rod 4 drives the wedge plate 5 to move and press the button 3. When the button 3 moves, it drives the L-shaped push plate 8 to move and simultaneously activates the alarm 2 to sound an alarm. The L-shaped push plate 8 moves in the direction of the button 3, pressing the pressure rod 9 to move downward. The bottom of the pressure rod 9 is "V" shaped and always in contact with the support plate 10. The downward movement of the pressure rod 9 opens the two sets of V-shaped support plates 10, and the mounting rod 12 falls, extending the escape route map. This makes it easier for people to find a reasonable escape route by following the alarm sound, reducing casualties caused by fire.
[0029] 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.
