[0003] How to prevent fires before they occur and extinguish them efficiently and quickly in the event of a fire is a problem that must be faced. Existing fire regulations require that buildings with large crowds of people be equipped with fire-fighting facilities. For crowded places, fire sprinkler equipment is required. Analysis of fire cases where fixed sprinklers have been installed shows that places where fixed sprinklers have been installed have not played their due role in preventing the spread of fire and extinguishing fires.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example See also Figure 1-Figure 7The figure shows a fire extinguishing sprinkler device, including a rotor 1, a stator 2, an upper cover 3, a lower cover 4, a coil 5, a terminal box 6, a first sleeve 7A, a second sleeve 7B, a control circuit board 8, an electromagnetic brake device 9, a detection device 10, a limit device 11, and a fastener 201. The stator 2 adopts a hollow through-hole design for the circulation of the fire extinguishing medium. The rotor 1 and the stator 2 constitute a first motor, and the rotor is arranged on the outside. In this embodiment, the stator is provided with a coil, and the terminal box 6 is provided with a central control circuit board. A connector that can rotate around the stator is movably connected to the lower end of the stator 2 of the first motor, and a nozzle is connected to the connector. The connector or the nozzle is transmission-connected to the rotor so that the nozzle structure can be driven to rotate when the rotor rotates. The upper cover 3 and lower cover 4 are respectively secured to the upper and lower ends of the first motor rotor via fasteners 201. In this embodiment, the fasteners are screws. The present invention employs a design with a hollow through-hole for the first motor stator 2. A control circuit board is connected to the stator, along with at least one detection device 10. Signals from the detection device 10 and the control circuit board 8 are used to control rotor rotation by turning on the power supply. A hollow through-hole water inlet pipe is provided on the first motor stator 2. A solenoid valve 12 is installed on the water inlet pipe. The solenoid valve 12 is electrically connected to the central control circuit board in the terminal box 6. The detection device transmits the detected signal to the central control circuit board, which then issues corresponding instructions based on the detected signal to control the opening and closing of the solenoid valve, the direction and angle of rotor rotation, the activation of alarms, and the transmission of status signals. The central control circuit board is electrically connected to a power adapter, which is connected to both an external mains power source and a backup power source. In the event of a power outage or mains circuit failure, the passive power supply can provide electrical energy to support fire sprinkler extinguishing and angle adjustment.In this embodiment, the first motor is equipped with a permanent magnet, and the corresponding stator is equipped with a coil winding electrically connected to the control circuit board. The upper cover 3 has a brake device 9 installed at the end. The brake device 9 is an electromagnetic brake device. The brake device 9 is used to control the inertia of the rotor. The structure of the electromagnetic brake device is a prior art and will not be elaborated on here. The central control circuit board serves as a signal command center, which receives, transmits, and distributes various action signals to different actuators of the equipment to perform actions. In this embodiment, the shaft center of the stator 2 adopts a hollow through-hole structure design. The fire extinguishing medium flows through the hollow through-hole of the first motor stator 2. The improved first motor stator 2 does not rotate during operation. The shaft end of the first motor stator 2 is designed with a thread for external mounting accessories. A first sleeve 7A and a second sleeve 7B are embedded between the stator 2 and the rotor 1. The rotor 1 is designed to have a rotation function. The maximum horizontal rotation angle of the rotor 1 is not more than 360°, and it only rotates when ≤360 ° range of forward and reverse rotation, the rotor rotation angle is controlled by the control circuit, when the horizontal rotation angle of the rotor 1 reaches 360 °, the limit device 11 transmits a signal to the control circuit, the control circuit outputs a signal to the control circuit board, and the electromagnetic brake device 9 is controlled by the control circuit board. At this time, the electromagnetic brake device 9 acts to control the rotor rotation inertia. When the limit device 11 is not started, it will not affect the operation of the rotor. The working power supply of the equipment is ≤36V low-voltage DC power. The equipment can meet two power supply working modes of connecting to the mains or DC. When the equipment is connected to the mains, it needs to be transformed into DC by a transformer for use by the equipment. The equipment is designed with a self-test function and a fault prompt light design. The self-test system can realize the status self-test of the device host. When the equipment fault is detected by self-test, the fault warning light will flash. The fault reminder function is used to remind the user to repair it in time. The equipment status can be transmitted to the monitoring background in real time. The first motor stator 2 adopts a hollow hole design, which can greatly reduce the equipment volume, realize equipmentization, and save costs. The first motor has horizontal angle adjustment capability, enabling precise alignment of the fire location and precise water spraying, concentrating the fire extinguishing medium at the fire point and achieving optimal fire extinguishing effectiveness. In this embodiment, the limiting device comprises a protrusion mounted on each of the first motor stator 2 and the upper cover. When the upper cover rotates with the rotor until the two protrusions abut, the upper cover and rotor cannot continue to rotate in that direction, thus acting as a limiting device.

[0020] To remotely monitor the status of the sprinkler system, a communication module can be installed on the sprinkler system. This module transmits data to the control console, allowing for simultaneous display of data on a PC or app. The communication technology used in the communication module is currently available and will not be elaborated on here.

[0021] In order for the connector 14 to rotate with the rotor 1 in this embodiment, the rotor 1 and the connector 14 are connected by a bracket 16. The bracket 16 is a plate. One end of the plate is fixedly connected to the rotor 1 by a screw, and the other end is fixedly connected to the connector 14. Of course, the bracket 16 can also be of other shapes. Its main function is to connect the connector 14 to the first motor rotor 1. As long as the bracket 16 can play this role, it should fall within the scope of protection of this application. Since the connector 14 and the stator 2 are movably connected and liquid flows through, it is necessary to have a bracket 16 between the first motor stator 2 and the connector 14. A movable joint structure 15 is provided, which includes an outer ring groove 21 provided on the outer ring of the first motor stator 2, an inner ring groove 141 provided on the inner wall of the connector 14, and spherical steel balls 151 filled between the inner ring groove 141 and the outer ring groove 21. The steel balls 151 can be inserted through a process hole provided on the connector, the process hole is communicated with the inner ring groove, and the steel balls can pass through the process hole. The steel balls 151 are loaded from the process hole, and the process hole can be blocked after being filled. The top screw can be used for blocking to form a rotatable connection structure. In order to achieve sealing between the two, a rubber sealing ring 152 is provided between the connector and the stator below the movable joint structure.

[0022] In this embodiment, the connector 14 has a hollow structure, which is connected to the nozzle 13 to realize the delivery of the fire extinguishing medium. The nozzle 13 in this embodiment is rotatably connected to the connector 14. The shape of the connector 14 can be set according to needs and is not limited to the shape in the drawings of this embodiment. As long as the connector 14 can achieve the same function of this application, it should be within the protection scope of this application. For more accurate fire extinguishing, the nozzle 13 and the connector 14 in this embodiment are also movably connected. The movable connection structure 15 between the connector and the stator can also be adopted between the nozzle 13 and the connector 14. Its specific structure will not be repeated here. The rotation between the connector 14 and the first motor stator 2 is a horizontal rotation, and the surface formed by the rotation between the nozzle and the connector is perpendicular to the above-mentioned horizontal direction, and is an up and down rotation. In this way, the nozzle adjustment angle can be basically without dead angles. In order to achieve the up and down adjustment of the nozzle 13, an up and down adjustment mechanism for adjusting the direction of the nozzle 13 is also included. The up and down adjustment mechanism includes a second motor 17 fixed relative to the rotor 1 of the first motor and a transmission mechanism that drives the output shaft of the second motor 17 to cooperate with the nozzle 13. The rotation of the second motor 17 is transmitted to the nozzle 13 through the transmission mechanism to adjust the orientation angle of the nozzle 13 up and down. The second motor 17 is mounted on a motor bracket 18, which is fixed to the rotor 1 of the first motor. The second motor 17 moves with the rotor 1. The transmission mechanism includes a driving gear 19 connected to the output shaft of the second motor 17, and a passive gear 20 connected to the nozzle, and the passive gear 20 is engaged with the driving gear 19. The second motor 17 drives the driving gear 19 to rotate, which drives the passive gear 20 to rotate, thereby rotating the nozzle 13, thereby achieving up and down adjustment of the nozzle 13.
