The fire detection sensor 31 may be a differential or constant temperature thermal sensor, a photoelectric smoke sensor, a thermal and smoke composite sensor, and the like.

When the fire is detected by the fire detection sensor 31, the control board 33 operates the wireless module so that the fire detection signal is transmitted to the repeater 20, and checks the state of the battery 35 to be below a reference voltage. When discharged to the alarm, the alarm 35 or the lamp blinks to inform the manager to replace the battery 35, and periodically checks whether the fire detection sensor 31 and the wireless module are normal and notifies the manager. The fire detector 30 is controlled.

The wireless repeater 20 is installed on each floor of the building to receive a fire detection signal wirelessly from the wireless fire detectors 30 installed on the floor, and transmits the received fire detection signal to the receiver 10 wirelessly or by wire. do.

The receiver 10 is installed on the lower floor of the building, for example, on the first floor, and receives a fire detection signal from the wireless repeater 20 by wire or wireless, and when a fire occurs, fire occurs outside the fire station, police station, building manager, etc. Send information to inform, activate an alarm to help people in the building evacuate, and activate sprinklers to extinguish the fire.

The receiver 10 is a storage unit for storing and managing the information received from the wireless repeaters 20 by wire or wirelessly through the communication module and the identification number of the fire detector 30, and fires.

Can be. As an example, the breaking unit may include a network interface to connect a LAN cable.

2 and 3, the mechanical configuration of the wireless fire detector 30 according to the present invention is composed of a base 40, a body 50, a plate 60, a fire detection sensor 31, control The board 33, the antenna 37, the battery 35, and the like are mounted.

The base 40 is installed on the ceiling of the building, the body 50 is coupled to the front of the base 40, the plate 60 is interposed between the base 40 and the body 50 Separate their space.

A fire detection sensor 31 and a control board 33 are built in the front space formed by the base 40 and the plate 60, and in the rear space formed by the body 50 and the plate 60, The battery 35 is built.

A support jaw 41 is formed on the inner wall of the base 40. An opening 43 is formed in a part of the support jaw 41, and an assembly protrusion 45 is formed at an end of the support jaw 41 connected to the opening 43.

Through the extension line of the assembly protrusion 45, a perspective hole 47 is formed at the bottom of the base 40 to determine whether the assembly protrusion 45 and the assembly groove 65 of the plate 60 are normally engaged. Make sure to check.

The diaphragm 60 is mounted on the support jaw 41, and an assembly groove 65 inserted into the assembly protrusion 45 is formed behind the edge of the base 40.

The diaphragm 60 is inserted into the base 40 and is supported on the support jaw 41.

When the plate 60 is rotated after the assembly protrusion 45 is inserted into the base 40 so as to be located in the opening, the assembly protrusion 45 is inserted into the assembly groove portion 65, so that the plate ( 60) and the base 40 are assembled and assembled. When the assembled plate 60 is rotated in the opposite direction, the plate 60 and the base 40 are disassembled while the assembly protrusion 45 leaves the assembly groove 65.

A battery 35 is mounted on the rear surface of the plate 60. Since the plate 60 and the base 40 are quickly and easily combined and separated through the assembly protrusion 45 and the assembly groove 65 without separate coupling tools such as a screwdriver or a bolt, the rear surface of the plate 60 The replacement operation of the battery 35 mounted on the is efficient.

A battery 35 mounting groove structure may be formed on the rear surface of the plate 60 so that the battery 35 is replaceable, and the mounting groove structure will be formed together during injection molding of the plate 60.

The mounting groove structure occupies a fairly large area in the plate 60, and makes the structure of the plate 60 more complicated.

Therefore, when the product is ejected after the plate 60 is ejected (ie, the molded plate 60) (ejecting), the design of the mold becomes complicated due to the use of a large number of eject pins as the area is large. There is a problem in that defects such as occurrence of defects occur, and in particular, bending or damage of the hook of the battery 35 mounting groove structure (protrusion to hold the battery 35 badly) occurs frequently during ejection. Therefore, the above-described problem can be solved by separately manufacturing the casing 70 on which the battery 35 is mounted, and by assembling and coupling the casing 70 on which the battery 35 is mounted to the diaphragm 60. That is, the casing 70 is separately manufactured to simplify the structure of the plate 60, and the separately manufactured casing 70 is also simplified than the mounting groove structure formed on the plate 60, thereby solving the above-described problem.

For reference, the detachable means for allowing the casing 70 to be assembled and detachably attached to the plate 60 will be described later.

The body 50 is formed with a concave seating portion 51 in which a fire detection sensor is seated in the center of the inside, and smoke or heat penetrates to the outside around the seating portion 51 so that smoke or heat flows into the fire detection sensor 31 inside. An inflow hole 53 is formed so as to be possible.

The rear opening of the body 50 is covered by the plate 60 is coupled. The plate 60 may be coupled to the body 50 using bolts, or may be coupled to the body 50 through an assembly structure such as the cooking protrusions and assembly grooves 65.

The control board 33 is built in the body 50. The fire detection sensor and the antenna 37 are mounted on the front surface of the control board 33. The antenna 37 penetrates the body 50 and is exposed to the front. A communication module is mounted on the rear surface of the control board 33, and a connector 34 to which the battery 35 is electrically connected is mounted.

Hereinafter, with reference to FIGS. 4 and 5, the desorption means for detachably coupling the casing 70 to the diaphragm 60 will be described. In describing the desorption means, the direction is determined based on FIGS. 4 and 5.

The desorption means includes a coupling block 100, an insertion hole 110, an insertion rod 120, a spring 130, a front-rear plate 140, a push protrusion 126, and a spring member 150.

The coupling block 100 is provided on the lower surface of the plate (60).

The insertion hole 110 is formed in the diaphragm and the coupling block 100, the insertion rod 120 is formed protruding in the lower portion of the casing 70, it is possible to be inserted into the insertion hole 110 to move up and down do.

The spring 130 is disposed on the bottom of the insertion hole 110 to elastically support the insertion rod 120 to be elevated. A support plate 131 is coupled to an upper portion of the spring 130 to support a lower end of the insertion rod 120. The support plate 131 is caught in the locking jaw 111 formed in the insertion hole 110 so that the lifting range is limited.

The front-rear plate 140 is disposed inside the coupling block 100 connected to the insertion hole 110 and adjacent to the outer periphery of the insertion rod 120, and a locking tooth 143 is formed at the center of the front surface. And, the guide portion 141 for guiding forward and backward in the central portion of the rear surface is protruded.

On the surface of the insertion rod 120, teeth 123 engaged with the engaging teeth 143 are engaged. The engaging teeth 143 and the teeth 123 have a horizontal structure at the bottom and an inclined structure at the top. So, when the insertion rod 120 is inserted into the insertion hole 110 and descends, the insertion rod 120 is inserted while the teeth 123 pushes the locking teeth 143, and after being inserted, the teeth 123 are locking teeth. The insertion rod 120 is prevented from being lifted by being engaged with the 143 and engaged.

The push protrusion 126 is formed to be inclined on the surface of the insertion rod 120 toward the upper side of the teeth 123. When the insertion protrusion 120 descends, the push protrusion 126 contacts the front-rear advance plate 140 to push the front-rear advance plate 140 backward.

The upper portion of the push projection 126 extends to the coupling plate 121, and the guide hole 116 into which the upper portion of the push projection 126 is inserted is formed in the insertion hole 110, so that the teeth 123 It is preferable that the insertion rod 120 is inserted into the insertion hole 110 in the direction in which the and corresponding teeth 123 are aligned.

The winding member 150 is composed of a housing 151 and a plate spring 153 that is embedded inside the housing 151 and is exposed to the outside of the housing 151.

The leaf spring 153 accumulates elastic energy when it is wound, and is gradually released using the accumulated energy. That is, when the end of the plate spring 153 partially exposed to the outside of the housing 151 is pushed, the exposed plate spring 153 enters the housing 151 and winds up, accumulating elastic energy while winding, and pushing When the end of the leaf spring 153 is released, the leaf spring 153 comes out of the housing 151 and returns to its original shape. At this time, the leaf spring 153 does not come out of the housing 151 momentarily, but gradually comes out.

The process in which the casing is coupled to and separated from the plate through the detachable means configured as described above will be described with reference to FIG. 5.

When the casing is coupled to the diaphragm, the insertion rod 120 provided at the lower portion of the casing is inserted into the insertion hole 110 formed in the diaphragm and the mating block 100. At this time, the upper portion of the push protrusion 126 and the guide groove 116 are matched.

Referring to [A] of FIG. 5, when the insertion rod 120 is inserted into the insertion hole 110, the teeth 123 of the insertion rod 120 are engaged with the locking teeth 143 of the front-rear plate 140. The insertion rod 120 is coupled so that it cannot be reversed, and the spring 130 elastically supports the insertion rod 120 so that the engagement state of the teeth 123 and the locking teeth 143 is maintained.

When separating the casing from the plate, press the casing down so that the insertion rod 120 descends into the insertion hole 110.

Referring to [B] of FIG. 5, when the insertion rod 120 is lowered, the push protrusion 126 pushes the front-rear plate 140 to reverse. Then, the coupling between the teeth 123 and the locking teeth 143 is released. At this time, the front and rear plates 140 are retracted while the plate spring 153 of the spring member 150 is wound into the housing 151.

Referring to [C] of FIG. 5, when the force pressing the casing is extinguished, the spring 130 is lifted to the original position with the restoring force, and the leaf spring 153 of the spring member 150 has a housing ( 151) is gradually coming out, and the front and rear plates 140 are not advanced yet, so that the teeth 123 and the locking teeth 143 are before being combined.

So, when the operator separates the casing from the plate and the coupling block 100, the inserting rod 120 is easily pulled out of the insertion hole 110 and separated as the casing is pressed down and lifted.

However, even if an unintentional external impact is applied and the insertion rod 120 temporarily descends into the insertion hole 110 to become the same state as [C] of FIG. 5, after a certain time (within a few seconds) has elapsed. The same state as [A] prevents the casing from being unintentionally separated from the plate.

In describing the present invention, the wireless automatic fire detection system having a specific shape and structure has been described with reference to the accompanying drawings. However, the present invention can be modified and changed in various ways by those skilled in the art. It should be interpreted as being within the scope of protection.
