Description

Technical Field

[0001] This application relates to a smoke alarm device for building corridors. Background Technology

[0002] A stairwell smoke alarm device is an instrument that prevents fires by monitoring the concentration of smoke. Also known as a smoke detector or smoke alarm, it uses an ionization smoke sensor, a technologically advanced and reliable sensor widely used in various fire alarm systems. Its performance is far superior to gas-sensitive resistor-type fire alarms. The smoke detector is simply another name for a smoke detector or smoke alarm; it is easy to install, highly effective, and widely used in important fire-prevention locations such as homes, factories, office buildings, hospitals, schools, and museums.

[0003] Existing patent publication number CN215025579 discloses a smoke alarm and fire extinguishing device for stairwells, relating to the field of fire extinguishing technology. It includes a mounting plate, a sensor fixedly connected to the bottom of the mounting plate, a mounting frame fixedly connected to the bottom of the sensor, a hanging bracket movably connected to the center of the mounting frame, a gear fixedly connected to the upper end of the hanging bracket located inside the mounting frame, a first motor fixedly connected to one side of the bottom of the mounting frame, and a rotating gear meshing with the gear fixedly connected to the output shaft of the first motor located at the bottom of the mounting frame. A nozzle is arranged between the two side plates of the hanging bracket, and both sides of the nozzle are rotatably connected to the two side plates of the hanging bracket via rotating shafts. One of the rotating shafts has a worm gear at one end located inside the side plate of the hanging bracket. This invention, through the cooperation of the hanging bracket and the adjusting frame, allows for adjustment of the spray angle of the device in various directions during use, enabling convenient extinguishing of fires at different locations, making it more convenient to use.

[0004] Smoke alarm devices in stairwells are equipped with water spray structures to spray water in the event of a fire to prevent the fire from spreading, such as the smoke alarm device mentioned above. However, the sprinkler heads in the water spray structure are always exposed to the outside when not in use, and the spray holes of the sprinkler heads are prone to clogging. In the event of a fire, this will affect the spraying effect and reduce the service life of the water spray structure.

[0005] Therefore, it is desirable to provide a smoke alarm device for building corridors. Utility Model Content

[0006] This embodiment provides a corridor smoke alarm device that solves the problem that when the sprinkler head in the sprinkler structure is not in use, it is always exposed to the outside, the spray holes of the sprinkler head are easily blocked, and the sprinkler effect will be affected in the event of a fire.

[0007] According to one aspect of this application, a stairwell smoke alarm device is provided, including a ceiling plate, a mounting frame fixed to the bottom of the ceiling plate by a fixing structure, a smoke alarm fixed in the middle of the bottom of the mounting frame, and the stairwell smoke alarm device further comprising:

[0008] A water spray structure, wherein the water spray structure is disposed within a mounting frame;

[0009] A protective structure is provided at the bottom of the water spray structure.

[0010] Furthermore, the fixing structure includes a mounting plate, a mounting groove, a limiting rod, a spring, a fixing plate, a locking block, a connecting rod, a through hole, and a pull plate. The mounting plate is symmetrically fixed at the front and rear ends of the bottom of the top plate.

[0011] Furthermore, each of the top edges of the mounting frame sidewalls corresponding to the mounting plate is provided with a mounting groove. Limiting rods and springs are fixed on both sides of the sidewalls away from the mounting plate in the mounting grooves. The springs are sleeved on the outside of the limiting rods, and the other ends of the limiting rods and springs are fixed to one sidewall of the fixing plate.

[0012] Furthermore, the fixing plate has locking blocks fixed on both sides of its side wall away from the limiting rod, and the locking blocks engage with the mounting plate.

[0013] Furthermore, a connecting rod is fixed to one side wall of the fixing plate on both sides of the limiting rod. A through hole is provided at the top of the mounting frame side wall corresponding to the connecting rod, and the other end of the connecting rod passes through the through hole and is fixed to the side wall of the pull plate.

[0014] Furthermore, the water spray structure includes a second fixed plate, a motor, a water supply pipe, a third fixed plate, a connecting pipe, and a spray head. The second fixed plate is fixed to one end of the bottom of the top plate, and the motor is fixed to the side wall of the second fixed plate.

[0015] Furthermore, a water supply pipe is fixed to the output end of the motor through the second fixing plate, and the other end of the water supply pipe is rotatably connected to the side wall of the third fixing plate. The top end of the third fixing plate is fixed to the bottom of the top plate.

[0016] Furthermore, a connecting pipe is fixed in the middle of the side wall of the water supply pipe, the top of the connecting pipe passes through the top plate, and multiple sets of spray heads are fixed on the top of the water supply pipe on both sides of the connecting pipe.

[0017] Furthermore, the protective structure includes a connecting rod and an arc-shaped baffle. The arc-shaped baffle is symmetrically arranged on both sides of the bottom of the water supply pipe, and the position of the arc-shaped baffle corresponds to that of the spray head.

[0018] Furthermore, the bottom of the mounting frame corresponding to the arc-shaped baffle is provided with an opening, and two connecting rods are fixed on the top two sides of the arc-shaped baffle, with the top of the connecting rods fixed to the bottom of the water supply pipe.

[0019] The advantages of this application are:

[0020] 1. By installing a mounting frame at the bottom of the base plate, the water spray structure is set inside the mounting frame at the top and bottom. When the water spray structure is not in use, the motor drives the water supply pipe to rotate, turning the spray head to the top of the water supply pipe. At this time, the arc-shaped baffle in the protective structure blocks the opening, which can store the water spray structure inside the mounting frame, preventing dust from clogging the spray holes on the spray head, avoiding the situation that affects the spraying effect in the event of a fire, and also improving the service life of the water spray structure.

[0021] 2. The mounting frame is fixed to the top plate by a fixing structure. By pulling the pull plate in the fixing structure, the locking block can be pulled into the mounting groove, separating the locking block from the mounting plate, thereby allowing the mounting frame to be removed. This facilitates disassembly and maintenance of the water spray structure, improving the convenience of the smoke alarm device. Attached Figure Description

The limiting rods 203 are telescopic and limit the springs 204 to prevent the springs 204 from being overstretched or compressed.

[0039] The fixing plate 205 has two locking blocks 206 fixed on its side walls away from the limiting rod 203, and the locking blocks 206 are engaged with the mounting plate 201.

[0040] A connecting rod 207 is fixed to the side wall of the fixing plate 205 on both sides of the limiting rod 203. A through hole 208 is provided at the top of the side wall of the mounting frame 3 corresponding to the connecting rod 207. The other end of the connecting rod 207 passes through the through hole 208 and is fixed to the side wall of the pull plate 209.

[0041] The water spray structure 5 includes a second fixing plate 501, a motor 502, a water supply pipe 503, a third fixing plate 504, a connecting pipe 505, and a spray head 506. The second fixing plate 501 is fixed to one end of the bottom of the top plate 1, and the motor 502 is fixed to the side wall of the second fixing plate 501.

[0042] The output end of the motor 502 passes through the fixing plate 2 501 and is fixed with a water supply pipe 503. The other end of the water supply pipe 503 is rotatably connected to the side wall of the fixing plate 3 504. The top of the fixing plate 3 504 is fixed to the bottom of the top plate 1.

[0043] A connecting pipe 505 is fixed in the middle of the side wall of the water supply pipe 503. The top end of the connecting pipe 505 passes through the top plate 1. Multiple sets of spray heads 506 are fixed on the top of the water supply pipes 503 on both sides of the connecting pipe 505. The connecting pipe 505 is configured as a flexible hose with sufficient length to allow the water supply pipe 503 to rotate.

[0044] The protective structure 6 includes a connecting rod 601 and an arc-shaped baffle 602. The arc-shaped baffle 602 is symmetrically arranged on both sides of the bottom of the water pipe 503, and the position of the arc-shaped baffle 602 corresponds to that of the spray head 506.

[0045] The bottom of the mounting frame 3 corresponding to the arc-shaped baffle 602 is provided with an opening 7, and the top two sides of the arc-shaped baffle 602 are fixed with connecting rods 601, the top of which is fixed to the bottom of the water pipe 503.

[0046] Working principle: All electrical components mentioned in the application are connected to an external power supply and control device during use. First, the top plate 1 is fixed to the ceiling, connecting the connecting pipe 505 to an external water source. Then, the mounting frame 3 is fixed to the top plate 1 via the fixing structure 2. During fixing, pull the pull plate 209 to pull the locking block 206 into the mounting groove 202, then make the top of the mounting frame 3 abut against the top plate 1, aligning the locking block 206 with the slot on the mounting plate 201. Then, release the pull plate 209, causing the locking block 206 to spring back under the action of the spring 204 and lock into the corresponding slot, completing the fixing of the mounting frame 3. When the water spray structure 5 is not in use, the motor 502 drives the water supply pipe 503 to rotate, rotating the spray head 506 to the top of the water supply pipe 503. At this time, the arc-shaped baffle 602 in the protective structure 6 covers the opening 7, allowing the water spray structure 5 to be stored in... The mounting frame 3 prevents dust from clogging the spray holes on the sprinkler head 506, thus avoiding any impact on the spraying effect in the event of a fire. When a fire breaks out in the corridor, the smoke detector 4 will send a signal to the control component, triggering an alarm. At this time, the motor 502 will also be activated, driving the water pipe 503 to rotate and rotate the sprinkler head 506 to the bottom of the water pipe 503, allowing it to pass through the opening 7. At this time, the arc-shaped baffle 602 rotates to the top of the water pipe 503, and the sprinkler head 506 sprays water onto the ground to prevent the spread of fire. When maintaining the spray structure 5, pulling the pull plate 209 in the fixing structure 2 can pull the locking block 206 into the mounting groove 202, separating the locking block 206 from the mounting plate 201, thereby allowing the mounting frame 3 to be removed. This facilitates disassembly and maintenance of the spray structure 5, improving the convenience of the smoke alarm device.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
