[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0024] Example

[0025] See also Figure 1-Figure 7, as shown in the figure, is a fire-fighting intelligent sprinkler equipment, 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 is designed with a hollow through hole for the circulation of a fire-extinguishing medium. The rotor 1 and the stator 2 form a first motor, and the rotor is arranged outside. In this embodiment, a coil is arranged on the stator, and a central control circuit board is arranged in the terminal box 6. 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 the lower cover 4 are respectively fixed to the upper and lower ends of the first motor rotor by fasteners 201. In this embodiment, the fasteners are screws. The present invention adopts a hollow through-hole design for the first motor stator 2; a control circuit board is connected to the stator, and at least one detection device 10 is also included. The detection device 10 and the control circuit board 8 signal instructions are used to turn on the power to control the rotation of the rotor. The first motor stator 2 is provided with a hollow through-water inlet pipeline, and a solenoid valve 12 is installed on the water inlet pipeline. The solenoid valve 12 is electrically connected to the central control circuit board of the terminal box 6. The detection device transmits the detected signal to the central control circuit board. The central control circuit board gives corresponding instructions according to the detection signal to control the opening and closing of the solenoid valve, as well as the direction and angle of rotation of the rotor, and the direction and angle of rotation of the rotor and the alarm opening and status signal transmission. The central control circuit board is electrically connected to a power adapter, and the power adapter is externally connected to the mains power supply and electrically connected to the backup power supply. In the case of power outage or mains circuit failure, the passive power supply can provide electrical energy to support fire extinguishing, 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 is equipped with a brake device 9 structure design, and the brake device 9 is an electromagnetic brake device. The brake device 9 is used to control the rotor inertia. The structure of the electromagnetic brake device is a prior art and will not be elaborated in detail 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 is designed with a hollow through-hole structure design, and 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. The first sleeve 7A and the second sleeve 7B are inlaid 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 only ≤360° 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, and the control circuit outputs a signal to the control circuit board. The electromagnetic brake device 9 is controlled by the control circuit board. At this time, the electromagnetic brake device 9 controls the rotation inertia of the rotor. 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 direct current. The equipment can meet the two power supply working modes of connecting to the mains or direct current. When the equipment is connected to the mains, it needs to be transformed into direct current by a transformer for use by the equipment. The equipment has a designed self-checking function and a fault prompt light design. The self-checking system can realize the status self-check of the device host. When the equipment fails, 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 volume of the equipment, realize the intelligence of the equipment, and save costs. The first motor has the ability to adjust the angle in the horizontal direction, so that it can be more accurately aligned with the fire position, accurately spray water, and concentrate the fire extinguishing medium at the fire point, thereby achieving a better fire extinguishing effect. In this embodiment, the limit device is to install a protrusion 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 the rotor cannot continue to rotate in this direction, which plays a limiting role.

[0026] In order to know the status of the sprinkler equipment remotely, a communication module can be installed on the sprinkler equipment, and the data can be transmitted to the console through the communication module, so that the data can be displayed synchronously on the PC or APP. The communication technology of the communication module is a conventional technology on the market, so it will not be elaborated in detail here.

[0027] 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 in this embodiment. The bracket 16 is a plate, one end of which is fixedly connected to the rotor 1 by screws, 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 belong to the protection scope of this application. Since the connector 14 is movably connected to the stator 2 and liquid flows through, it is necessary to connect 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 is blocked after being filled. The process hole can be blocked by a top screw 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.

[0028] 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 the present application, it should be within the protection scope of the present 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. The specific structure thereof 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 a vertical rotation. In this way, the nozzle adjustment angle can be basically free of 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 for driving 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 installed on a motor bracket 18, and the motor bracket 18 is fixed on 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 meshed with the driving gear 19. The second motor 17 drives the driving gear 19 to rotate, which drives the passive gear 20 to rotate, so that the nozzle 13 rotates, thereby realizing the up-and-down adjustment of the nozzle 13.
