Abstract
Description
Technical Field
[0001] The present invention relates to a fire sprinkler having a sprinkler connection piece for connecting a sensor carrier according to claim 1, a sensor carrier having a carrier connection piece for mounting on a fire sprinkler according to claim 11, and a fire fighting system according to claim 14. Background Art
[0002] Fire sprinklers are devices that are placed on the ceiling and / or walls of a building and are triggered in the event of a fire. In this case, the extinguishing agent from the pipeline system is distributed to a specific building area, thereby extinguishing the fire or preventing or at least slowing down its spread. In order to detect the fire early and trigger the fire sprinklers in time, sensors distributed in the building are used, such as fire sensors, temperature sensors, flame sensors, and smoke sensors.
[0003] That is, in the same building area to be monitored and protected from fire, both fire sprinklers and / or sprinklers and sensors are provided. All these elements must be fixed to the ceiling or wall of the building. In the case where all the attached elements need to be installed separately at different locations in the building area to be protected, the installation of the fire protection system is relatively complicated. In the case where each element needs to be checked and replaced as needed, the inspection and maintenance work is also relatively complicated. Summary of the invention
[0004] The object of the present invention is to provide a solution whereby the installation, inspection and maintenance of a fire protection system comprising fire sprinklers and sensors is simplified.
[0005] The solution of the present invention to achieve the above-mentioned object is a fire sprinkler with a sprinkler connection member for connecting or accommodating a sensor carrier according to claim 1, a sensor carrier with a carrier connection member for mounting on a fire sprinkler according to claim 11, and a fire fighting system according to claim 14. More features and embodiments are described in the dependent claims, and their advantages are explained below.
[0006] The invention is based on a fire sprinkler with a connection for a sensor, whereby a fire sprinkler with a dual function (detection and extinguishing) can be easily applied in the area to be protected and no fire sensors need to be installed at other locations in the ceiling or walls of the area to be protected in addition to the fire sprinkler. The sensors installed on the fire sprinkler can be connected to a fire control unit or a building management system. To facilitate the replacement of the sensors, they are arranged on a removable sensor carrier which is releasably fastened to the fire sprinkler. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 A top view of a fire sprinkler with various sensors.
[0010] The drawings show possible exemplary embodiments which are explained below. DETAILED DESCRIPTION
[0011] The fire sprinkler of the present invention comprises a sprinkler body 1 having a channel 11 through which the fire extinguishing agent flows from an inlet end 111 to an outlet end 112 in use, and comprises a closure 2 which seals the channel 11 to prevent the fire extinguishing agent from passing through. According to the present invention, the sprinkler body is provided with at least one mechanical sprinkler joint 31 for anchoring the sensor carrier 4 on the sprinkler body 1 (see Figure 1a , Figure 1b and Figure 2 ).
[0012] The sensor carrier 4 of the present invention comprises a carrier body 41, which is equipped with at least one sensor 42, at least one signal transmitter 44, and at least one mechanical carrier joint 43 for anchoring the carrier body 41 on the fire sprinkler. The sensor 42 is preferably suitable for detecting fire, and is, for example, a temperature sensor, a flame sensor or a smoke sensor 421. However, the advantages of the present invention are also achieved when other types of sensors 42 that are not necessarily used for detecting fire are used. Accordingly, for example, a burglar alarm 422, a camera 423 for video surveillance, or any other device used in building management for checking status and monitoring can also be arranged as a sensor 42 on the fire sprinkler. The sensor 42 is connected to the signal transmitter 44, so that the information determined by the sensor can be transmitted to the signal transmitter 44. When the sensor carrier 4 is installed on the fire sprinkler, the mechanical sprinkler joint 31 is coupled to the mechanical carrier joint 43, so that the sensor carrier 4 is firmly anchored on the sprinkler body 1.
[0013] The signal transmitter 44 is used to transmit the signal from the sensor 42 to the fire sprinkler or the surrounding environment, in particular for fire control. The signal transmitter 44 is, for example, an acoustic device that outputs an acoustic signal when the sensor 42 detects a fire or a burglary. The signal transmitter 44 can also be an electronic device for outputting an electromagnetic signal, such as a Bluetooth device, a Wifi device, or the like. The electromagnetic signal is received by the fire sprinkler, specifically, the fire sprinkler is equipped with a corresponding signal receiver. In a preferred embodiment of the present invention, the signal transmitter 44 is an electrical carrier connector 44 for establishing an electrical connection between the signal transmitter 44 and the fire sprinkler. In this case, the sprinkler body 1 of the fire sprinkler is equipped with an electrical sprinkler connector 32. When the sensor carrier 4 is installed on the fire sprinkler, the electrical carrier connector 44 is coupled to the electrical sprinkler connector 32, so that the information measured by the sensor 42 can be transmitted to the fire sprinkler. It is also preferred that, as an alternative or supplementary solution for transmitting information from the sensor carrier 4 to the fire sprinkler, the electrical sprinkler connector and the carrier connectors 32, 44 are also used to power the sensor carrier 4. Sensor carrier 4 can also be provided with a battery in addition or as an alternative.
[0014] In order to obtain power supply, the sensor carrier 4 can be connected to the fire sprinkler through the electrical sprinkler connector and the carrier connectors 32 and 44 , and is additionally equipped with a backup battery to cope with power failure.
[0015] The mechanical connection between the sensor carrier 4 and the nozzle body must be releasable to facilitate replacement of the sensor carrier 4, and this can be achieved in various ways. Possible ways include:
[0016] ● The connection is made by threads, in which case the mechanical spray head connector 31 is an external thread and the mechanical carrier connector 43 is an internal thread, or vice versa;
[0017] ● This is achieved by means of a bayonet connection, in which case the mechanical spray head connection 31 is a groove and the mechanical carrier connection 43 is a tab extending into this groove, or vice versa;
[0018] ● The connection is made by magnets, wherein the mechanical spray head joint 31 or the mechanical carrier joint 43 is a magnet, and the carrier body 41 or the spray head body 1 has a ferromagnetic material. As an alternative, the mechanical spray head joint 31 and the mechanical carrier joint 43 can also be magnets with opposite polarities.
[0019] ● The connection is made by snapping a male component into a female component like a conventional electrical socket or like a door latch, in which case the mechanical spray head connector 31 is the female component and the mechanical carrier connector 43 is the male component that mates with it, or vice versa;
[0020] The connection between the electrical carrier connector 44 and the electrical sprinkler connector 32 must also be releasable in order to replace the sensor carrier 4, and this is achieved by known means. It is particularly preferred that an electrical connection is established between the sensor carrier 4 and the sprinkler body 1 while mechanically connecting the sensor carrier 4. This ensures that the sensor carrier 4 can be quickly and easily installed and removed from the fire sprinkler. Possible ways are, for example:
[0021] ● The connection is made by threads, in which case the mechanical nozzle connector 31 is an external thread and the mechanical carrier connector 43 is an internal thread, or vice versa. In this case, once the sensor carrier 4 is screwed onto the nozzle body 1, an electrical connection can be made, for example, similar to a conventional light bulb with a screw base: the external thread and the internal thread can be made of conductive material and form a first electrical contact, and a second electrical contact is established by contact of the conductive material at another position.
[0022] ● This is achieved by a bayonet connection, in which case the mechanical nozzle connection 31 is a groove and the mechanical carrier connection 43 is a tab extending into the groove, or vice versa. In this case, once the sensor carrier 4 is fixed to the nozzle body 1, an electrical connection can be made like a conventional bulb with a bayonet connection.
[0023] ● The connection is made by magnets, wherein the mechanical nozzle joint 31 or the mechanical carrier joint 43 is a magnet, and the carrier body 41 or the nozzle body 1 has a ferromagnetic material. As an alternative, the mechanical nozzle joint 31 and the mechanical carrier joint 43 can also be magnets of opposite polarity. In this case, the electrical connection can be made by contact between the conductive parts of the nozzle body 1 and the sensor carrier 4 that are conductive and pressed toward each other by the magnet.
[0024] ● The connection is made by snapping the male component into the female component like a traditional electrical socket.
[0025] Preferably, in the case where the fire sprinkler is mounted on a wall or ceiling, the mechanical sprinkler connector 31 and the electrical sprinkler connector 32 are located in a visible, externally accessible area of the sprinkler body 1. The front side of the sprinkler body, where the outlet end 112 of the channel 11 is provided (but outside the channel 11), is a suitable location for the mechanical sprinkler connector 31 and the electrical sprinkler connector 32. In this way, the sensor carrier 4 can be replaced without opening or disassembling the sprinkler. Particularly preferably, a recess 5 is provided on this front side of the sprinkler body 1, which matches the geometry of the sensor carrier 4 so that the sensor carrier 4 does not protrude from the front side of the sprinkler entity 1 after installation. This ensures a particularly compact structure of the fire sprinkler.
[0026] In a preferred embodiment of the present invention, the sensor carrier is annular and is arranged in a corresponding annular recess 5 around the outlet end 112 of the channel 11 .
[0027] Preferably, the sensor carrier 4 includes all sensitive electronic components that need to be replaced, that is, not only the sensor 42, but also all other components necessary for the operation of the sensor 42. In this way, by replacing the sensor carrier, all sensitive components can be replaced at the same time. Preferably, the sensor carrier 4 includes the sensor 42 arranged on the sensor carrier, all sensitive electronic components that need to be replaced, and the carrier connector 43, but does not include other components, so as to simplify the structure as much as possible and reduce the cost.
[0028] Preferably, the nozzle body 1 has a component, such as an external thread or an internal thread, in the area of the inlet end 111 of the channel 11 for fixing the nozzle body 1 to the fire extinguishing agent supply L of the pipeline system. Particularly preferably, the channel 11 has two areas with different diameters: a narrower area 113 located on the side of the inlet end 111 and a wider area 114 located on the side of the outlet end 112. The narrower area 113 of the channel 11 can be equipped with a component 6 for forming a fire extinguishing agent spray beam, which flows out of the fire extinguishing agent spray beam during use. These components are, for example, an atomizer for generating water mist, a disk distributor for distributing the fire extinguishing agent spray beam to a larger area, or other structural measures for swirling the fire extinguishing agent spray beam and obtaining an ideal droplet size and a desired spray pattern, with a specific nozzle insert, such as a spiral, or with a spiral groove on the inner wall of the narrower area 113 of the channel 11. The wider region 114 of the passage 11 is preferably used to house the closure 2, which is completely or partially housed in the wider region. In a preferred embodiment of the present invention, the closure 2 is completely housed in the passage 11 and does not extend from the nozzle body 1, which ensures that the structure of the fire sprinkler is particularly compact.
[0029] The closure 2 preferably comprises a cover 21 and a seal 22, which is held by the cover 21 in a manner that resists the pressure of the pressurized fire extinguishing agent. Preferably, the cover 21 comprises a peeling element, which responds autonomously to the heat of the fire and peels the cover 21 off the nozzle body 1 in the event of a fire. As an alternative, the cover 21 can be fixed to the wider area 113 of the channel 11 at least at two fixing locations 211, wherein at least one fixing location 221 can be separated in the event of a fire. In this way, the cover 21 and the seal 22 can be pushed out of the channel 11 under the pressure of the fire extinguishing agent and the fire sprinkler is put into operation. The seal 22 is preferably stuck between the cover 21 and the shoulder 115 of the channel 11, which is arranged at the interface between the narrower area 113 and the wider area 114. The nozzle edge 116 between the shoulder 115 and the narrower area 113 is preferably designed so that the extinguishing agent flowing out has the desired consistency (droplet size) and the correct spray cone and spray angle (spray pattern). The nozzle edge 116 can, for example, have a rounded or inclined shape, and the shoulder 115 can be provided with structural measures 117 to swirl the extinguishing agent spray and obtain the ideal droplet size and the desired spray pattern.
[0030] In order to improve the aesthetics of the fire sprinkler, a cover round ornament 7 may be provided around the sprinkler body 1, which spans and covers the distance between the sprinkler body and the wall or ceiling on which the fire sprinkler is installed.
[0031] The fire sprinkler of the present invention can be applied in a fire fighting system including a fire controller. Preferably, the fire controller activates the fire sprinkler to extinguish the fire, for example, when two or more sensors 42, in particular adjacent sensors 42, report a fire, and / or when manually triggered by a fire brigade.
