Description

[0001] The present invention claims priority to patent application number 202411993470.2 filed on December 31, 2024, entitled "A Fire-Fighting Sprinkler Equipment," and patent application number 202411078956.3 filed on August 7, 2024, entitled "An Intelligent Household Fire Extinguisher," all of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of fire-fighting equipment, and in particular to a fire-fighting motor and fire-fighting equipment thereof. Background Art

[0003] The core of fire prevention and control lies in "preventing fires before they occur" and being able to extinguish them efficiently and quickly when they occur, minimizing casualties and property losses. Currently, fire regulations clearly stipulate that densely populated buildings must be equipped with fire-fighting facilities, especially those with large crowds, which require the installation of automatic fire sprinkler systems.

[0004] In the prior art, automatic fire extinguishing sprinkler systems generally use a passive fire extinguishing water spraying method after a fire occurs. That is, after a fire occurs, water is automatically sprayed to extinguish the fire. However, this method has the following problems: 1. Delayed response: The sprinkler head needs to reach a certain temperature (usually above 68°C) before it will start, resulting in a delay in responding to the fire in the early stages and missing the best time to extinguish the fire; 2. Limited coverage: The sprinkler water curtain is unevenly distributed, making it difficult to accurately cover the fire source, resulting in low fire extinguishing efficiency.

[0005] Therefore, it is necessary to provide a fire extinguishing device that can solve the defects of passive fire extinguishing water spray devices, improve the fire extinguishing performance of fire fighting facilities, and reduce casualties and property losses. The fire extinguishing motor used in conjunction with it is particularly important. Summary of the Invention

[0006] The purpose of the present invention is to provide a fire-fighting motor and fire-fighting equipment thereof, so as to solve the defects of the passive fire-fighting water spray device in the background technology.

[0007] To achieve the above-mentioned objectives, the present invention proposes a fire-fighting motor, comprising a stator, a rotor arranged outside the stator and rotating around the stator, a coil winding arranged on the stator or the rotor, and a medium channel for circulating a fire-extinguishing medium on the stator, the medium channel penetrating the stator; the flow direction of the fire-extinguishing medium in the medium channel is perpendicular to the plane formed by the rotation trajectory of any point on the rotor.

[0008] The present application takes the stator as the center, sets the rotor outside the stator, and sets the medium channel on the stator, so that the medium channel will not move regardless of whether the rotor rotates or not, ensuring that the fire extinguishing medium can flow normally in the medium channel.

[0009] Optionally, both ends of the rotor are equipped with end covers movably connected to the stator, and at least one of the end covers is equipped with a brake device.

[0010] The present application sets a brake device to brake the rotation of the stator to prevent the nozzle connected to the stator from moving, which can effectively fix the spraying direction and ensure the spraying effect.

[0011] Optionally, the brake device is an electromagnetic brake device, and a control circuit board electrically connected to the brake device is installed on the stator. The electromagnetic brake device is connected to an external power supply through a wire, and the control circuit board can control the on and off of the electromagnetic brake device and the external power supply.

[0012] The present application controls the setting of the circuit board to control the on-off of the electromagnetic brake device circuit, thereby controlling the on-off of the electromagnetic brake device circuit and controlling the brake device to fix the rotor to prevent the rotor from moving at will.

[0013] Optionally, the brake device includes a brake seat mounted on the end cover, an electromagnet mounted on the brake seat, a moving part movably mounted on the brake seat and corresponding to the electromagnet, a friction block mounted on the moving part for contacting and rubbing with the stator, a reset part mounted on the brake seat and abutting against the moving part, and a limiting structure arranged on the moving part and the brake seat.

[0015] Optionally, a central through hole is provided on the brake seat, the central through hole corresponds to the stator, and the size of the central through hole is larger than the size of the stator.

[0016] The present application avoids the stator by setting a hollow through hole, thereby preventing interference between the brake seat and the stator.

[0017] Optionally, the moving member includes a moving plate, a moving sleeve arranged on the moving plate and located in the central through hole, and an inner dimension of the moving sleeve is not less than a dimension of the stator.

[0018] The present application uses the setting of a movable plate and a movable sleeve to abut the reset member, so that the reset member can push the movable member to move, thereby driving the friction block to move and reset; by limiting the inner size of the movable sleeve, it is ensured that the movable member will not interfere with the stator.

[0019] Optionally, the friction block is mounted on the movable sleeve and is located between the end cover and the brake seat.

[0020] The present application places the friction block between the end cover and the brake seat, so that the movement of the friction block can contact and separate from the end cover.

[0021] Optionally, a rotation limiting structure is provided on the rotor and the mover, and the rotation limiting structure is used to prevent the rotor from excessively rotating, that is, the rotor rotates back and forth around the stator and can only rotate 360 ​​degrees in one direction.

[0022] The present application limits the rotation angle by setting a rotation limiting structure to ensure that the rotor does not rotate excessively.

[0023] Optionally, the rotation limiting structure includes a limiting protrusion provided on the stator, and a matching protrusion provided on the rotor corresponding to the limiting protrusion.

[0024] The present application limits the rotation angle of the rotor and the stator by setting a limiting protrusion and a matching protrusion, ensuring that the rotor can only perform a 360° reciprocating rotation.

[0025] Optionally, the rotation limiting structure further includes two proximity switches, which are symmetrically distributed about the connecting line between the stator center and the limiting protrusion, and when the rotor rotates, the proximity switches will sense the passing of the mating protrusion.

[0026] By setting a proximity switch, the present application can send a signal before the rotor rotates to the limit position, providing sufficient time for the activation of the brake device and reducing the impact of the direct hard collision between the limit protrusion and the matching protrusion on the rotation of the rotor.

[0027] Optionally, the limiting structure includes a countersunk hole provided on the movable plate, and a bolt installed in the countersunk hole and connected to the friction block.

[0028] The present application provides a countersunk hole to hide the bolt head and prevent the bolt head from affecting the stator.

[0030] The present application provides installation space for the reset part and the electromagnet by setting the first ring groove and the second ring groove, and the concentric setting with the center through hole ensures the uniformity of the force exerted by the electromagnetic fitting and the reset part on the moving part, avoiding the problem of the main body being stuck due to uneven force.

[0032] This application uses a spring as an elastic part to effectively push the moving part to reset, thereby driving the friction block to move synchronously and separating the friction block from the rotor; by setting the moving plate to a magnetic conductive material, it is ensured that the moving plate can be magnetically controlled by the electromagnet.

[0033] Optionally, a movable part movably connected to the stator is mounted on the end cover.

[0034] Optionally, the movable part may be a sleeve or a bearing.

[0035] The present application reduces the friction between the rotor and the stator during the rotation process by setting up movable parts.

[0036] The present application also discloses a fire extinguishing device, including a junction box, a nozzle that rotates synchronously with the rotor, a fire-fighting motor, a water inlet pipe being provided on the stator of the fire-fighting motor, and a connector that is movably connected to the stator being provided on the nozzle.

[0037] This application uses the setting of a nozzle to spray out the fire extinguishing medium to carry out fire extinguishing operations; uses the setting of a water inlet pipeline to connect the medium channel with an external water source through a pipeline. The fire extinguishing medium can be tap water, and a booster device, such as a booster pump, can be added to the water source to pressurize the fire extinguishing medium. A manual valve is designed at the end of the water supply pipe, which is used to shut off the water source for equipment maintenance.

[0038] Optionally, the fire extinguishing equipment further includes an up and down adjustment mechanism installed on the motor; a central control circuit board is installed in the junction box, and a solenoid valve connected to the central control circuit board is installed on the water inlet pipe.

[0039] This application adjusts the spray angle of the nozzle by setting up the upper and lower adjustment mechanisms; through the setting of the central control circuit board, the upper and lower adjustment mechanisms and the solenoid valve can be controlled to control the spray angle of the nozzle and the flow rate of the fire extinguishing medium.

[0040] Optionally, when the rotor drives the nozzle to rotate, the trajectory of any point on the nozzle forms a first plane, and when the up and down adjustment mechanism drives the nozzle to rotate, the trajectory of any point on the nozzle forms a second plane, which is perpendicular to the first plane.

[0041] The present application increases the range in which the fire extinguishing medium can be sprayed by setting the planes formed by the two rotating trajectories to be perpendicular to each other. That is, when the rotor drives the nozzle to rotate, the nozzle is directed to different directions, and the up and down adjustment mechanism can adjust the angle formed by the nozzle and the ground, adjust the distance at which the nozzle sprays the fire extinguishing medium, expand the range in which the nozzle can spray, and expand the fire extinguishing range of the fire extinguishing equipment.

[0042] Optionally, the up and down adjustment mechanism includes a bracket installed on the rotor, an adjustment power source installed on the bracket, a transmission structure connected to the adjustment power source and the nozzle, and a connecting piece movably connected to the stator and the nozzle.

[0043] In this application, the bracket is used to provide an installation position for other components of the upper and lower adjustment mechanism, so that the upper and lower adjustment mechanism and the nozzle can move synchronously with the rotor; the setting of the adjustment power source is used to provide the nozzle with up and down rotation, and provide power for adjusting the spray angle between the nozzle and the ground. The adjustment power source can be a motor; through the setting of the transmission structure, it is used to transmit the power output of the adjustment power source; the connecting piece is used to transmit the fire extinguishing medium in the medium channel to the nozzle.

[0044] Optionally, a protective cover is installed on the bracket, and a spray hole is provided on the protective cover. A blocking piece corresponding to the spray hole is installed on the nozzle. When the nozzle is adjusted up and down, the blocking piece will be driven to rotate synchronously.

[0045] The present application is used to protect the nozzle and the motor through the provision of a protective cover, to prevent the user from directly impacting the motor and the nozzle, and to avoid damage to the nozzle and the motor due to the impact; the provision of a spray hole is used to avoid the nozzle, so that the fire extinguishing medium will not be blocked by the protective cover, and the fire extinguishing medium can be smoothly sprayed out to extinguish the fire; the provision of a sealing member corresponding to the spray hole, that is, when no fire extinguishing operation is required, the spray hole can be blocked to strengthen the protection of the motor and the nozzle; the provision of the nozzle and the sealing member for synchronous rotation, so that the nozzle can drive the sealing member to be synchronously adjusted during rotation, so that the sealing member can open the spray hole while the nozzle can spray the fire extinguishing medium from the spray hole.

[0046] Optionally, the blocking member includes a connecting plate fixedly mounted on the nozzle, and an arc-shaped baffle mounted on the connecting plate, wherein the arc-shaped baffle corresponds to the ejection hole.

[0047] This application uses the setting of a connecting plate to drive the arc baffle and the nozzle to move synchronously.

[0048] Optionally, the orthographic projection of the nozzle on the second plane and the orthographic projection of the connecting plate on the second plane form an angle with the opening facing the arc baffle; when the nozzle is rotated to any angle, the orthographic projection of the nozzle on the second plane does not overlap with the orthographic projection of the connecting plate on the second plane.

[0049] The present application forms an angle between the nozzle and the connecting plate so that the movement trajectory of the fire extinguishing medium at the nozzle spraying point will not be blocked by the arc baffle.

[0050] Optionally, a fixing member is installed on the stator, and a fixing bracket is installed on the top of the fixing member.

[0051] The present application can fix the fire extinguishing equipment on the installation wall by setting the fixing bracket and the fixing parts.

[0052] Optionally, a sensor and an alarm are installed at the bottom of the protective cover, and the sensor and the alarm are connected to the central control circuit board.

[0053] The sensor in this application adopts an infrared or ultraviolet composite detection method. When a fire occurs in the protected area, the sensor captures the fire information in the first time and transmits it to each fire extinguishing action mechanism, and the fire extinguishing equipment starts working.

[0054] Optionally, the fire extinguishing equipment is further provided with a self-checking signal circuit connected to the control console via a signal, for self-checking faults of the fire extinguisher.

[0055] The self-check module in this application includes a fault sound and light warning module. By connecting the self-check module with the console signal, the status of the host of the fire extinguisher can be self-checked. When a fault is detected in the self-check, the fire extinguishing equipment will flash the fault warning light, and the fault reminder function is used to remind the user to repair the equipment in time. When the equipment fails, the fault signal is transmitted to the fire control alarm console through the central control circuit board. The console has two display designs, PC and APP, and the data is synchronized. When debugging and repairing the equipment, settings can be performed through the device USB interface or APP interface.

[0056] Compared with the prior art, the present invention provides a fire-fighting motor and fire-fighting equipment thereof, which have the following beneficial effects: This fire-fighting motor and its fire-fighting equipment, by setting the stator at a central position and providing a medium channel for the circulation of fire-extinguishing medium on the stator, will not interfere with the transportation of the fire-extinguishing medium even if the rotor rotates; it enables an innovative upgrade of the original fixed explosive fire-fighting sprinkler, more precise fire extinguishing, improved intelligence of fire-fighting equipment, and reduced risk of fire spread. The invention and application of this technology will greatly enhance the fire prevention and fire-fighting capabilities of the defense zone. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] The following is a detailed description with reference to the accompanying drawings and specific embodiments. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0074] The fire-fighting motor of the present application can be used in fire-fighting and other occasions, and of course can also be used in other similar application scenarios. The fire-fighting motor is described in detail below.

[0075] See attached Figure 1 — Figure 5 FIG2 is a schematic structural diagram of a preferred embodiment of a fire-fighting motor according to the present application. The fire-fighting motor comprises a stator 1, a rotor 2 disposed outside the stator 1 and rotating about the stator, and a coil winding 3 disposed on the stator 1. The stator 1 is provided with a medium channel 4 for circulating a fire-extinguishing medium, the medium channel 4 being disposed through the stator 1. The direction of flow of the fire-extinguishing medium in the medium channel 4 is perpendicular to a plane formed by the rotation trajectory of any point on the rotor 2, which can specifically be a plane formed by the rotation trajectory of any point on the outer wall of the rotor 2.

[0076] In the present application, the rotor 2 is arranged outside the stator 1, and the rotor 2 rotates around the stator 1; it should be noted that the rotor 2 is provided with a permanent magnet or electromagnet for excitation relative to the coil winding 3; of course, the coil winding 3 can also be arranged on the rotor 2, and the permanent magnet or electromagnet for excitation is arranged on the stator 1; the medium channel 4 is arranged for the circulation of the fire extinguishing medium, and the fire extinguishing medium can be tap water. By arranging the medium channel 4 on the rotor 1, when the motor is operating and the rotor 2 rotates, the medium channel 4 will not move, ensuring that the fire extinguishing medium can flow in the medium channel 4; the flow direction of the fire extinguishing medium in the medium channel 4 is perpendicular to the plane formed by the rotation trajectory of any point on the rotor, so that the entry end of the medium channel 4 for entering the fire extinguishing medium and the exit end of the fire extinguishing medium leaving the medium channel 4 are respectively located on the top and bottom ends of the stator 1, ensuring that when the rotor 2 rotates, it will not affect the fire extinguishing medium entering and leaving the medium channel 4.

[0077] See attached Figure 1 — Figure 3 As shown, in the present application, both ends of the rotor 2 are equipped with end covers 21 movably connected to the stator, and at least one end cover 21 is equipped with a brake device 5; a control circuit board 6 electrically connected to the brake device 4 is installed on the stator 1, and the control circuit board 6 can control the action of the brake device 5.

[0078] In this application, the end cover 21 is set to limit the two ends of the rotor 2 to ensure that the rotor 2 will not separate from the stator 1; the brake device 5 is set to stop the rotation of the rotor 2 to prevent the rotor 2 from rotating too far due to inertia, thereby ensuring the accuracy of the rotation angle. The brake device 5 can be an electromagnetic brake device; the control circuit board 6 is set to control the on and off of the coil winding 3 and the on and off of the brake device 5.

[0079] See attached Figure 2 — Figure 5 As shown, in the present application, the brake device 5 includes a brake seat 51 mounted on the end cover 21, an electromagnet 52 mounted on the brake seat 51, a moving part 53 movably mounted on the brake seat 51 and corresponding to the electromagnet 52, a friction block 54 mounted on the moving part 53 for contacting and rubbing with the stator 1, a reset part 55 mounted on the brake seat 51 and abutting against the moving part 53, and a limiting structure 56 arranged on the moving part 53 and the brake seat 51.

[0080] In the present application, the brake device 5 controls the on and off of the electromagnet 52 by the control circuit board 6, driving the friction block 54 to move, thereby braking the rotor; specifically, when the rotor 2 needs to be braked, the control circuit board 6 controls the electromagnet 52 to be connected to the external power supply. At this time, the electromagnet 52 generates a magnetic field, generates a magnetic force on the moving part 53, causes the moving part 53 to move, pushes the friction block 54 to move, causes the friction block 54 to contact the rotor 2, and brakes the rotor; and when the rotor 2 needs to rotate, the control circuit board 6 disconnects the electromagnet 52 from the external power supply, causes the electromagnet 52 to lose power and lose the magnetic field. At this time, the moving part 53 will not be affected by the magnetic force, but will be affected by the reset force of the reset part 55. The reset force of the reset part 55 pushes the moving part 53 to move, and the moving part 53 drives the friction block 54 to reset and move, so that the friction block 54 is separated from the moving block 53. At this time, the rotor 2 can rotate normally. It should be noted that the fire extinguishing equipment has two power supply working modes: connecting to the mains or direct current. The fire extinguishing equipment is also equipped with a storage battery and a power transformer. The mains electricity connected is transformed by the transformer and used as the power supply equipment.

[0081] See attached Figure 3 — Figure 5 As shown, in the present application, the brake seat 51 is provided with a central through hole 511 corresponding to the stator 1, and the brake seat 51 is provided with a first annular groove 512 and a second annular groove 513 concentrically arranged with the central through hole 511. The size of the first annular groove 512 is smaller than the size of the second annular groove 513, the reset member 55 is installed in the first annular groove 512, and the electromagnet 52 is installed in the second annular groove 513; it should be noted that the aperture of the central through hole 511 is larger than the size of the stator 1; the reset member 55 is a spring, one end of the spring is in contact with the bottom of the first annular groove 512, and the other end is in contact with the movable plate, and the movable plate is made of magnetic conductive material.

[0082] This application limits the size of the central through hole 511 so that the brake seat 51 can be installed on the end cover 21, ensuring that the brake seat 51 can rotate synchronously with the end cover 21; by concentrically arranging the central through hole 511, the first annular groove 512 and the second annular groove 513, the electromagnet 52 and the reset member 55 apply a uniform force to the movable member 53.

[0083] See attached Figure 3 — Figure 5 As shown, in the present application, the moving member 53 includes a moving plate 531, a moving sleeve 532 disposed on the moving plate 531 and located in the central through hole 511, and the inner dimension of the moving sleeve 532 is not less than the dimension of the stator. In the present application, the moving plate 531 cooperates with the electromagnet 52 and the reset member 55, so that the electromagnet 52 and the reset member 55 can control the movement of the friction block 54.

[0084] See attached Figure 3 — Figure 5 As shown, in the present application, the friction block 54 is mounted on the moving sleeve and is located between the end cover and the brake seat, thereby ensuring that the movement of the friction block can contact and separate from the rotor 2.

[0085] See attached Figure 3 — Figure 5 As shown, in the present application, the limiting structure 56 includes a countersunk hole 561 provided on the movable plate 531, and a bolt 563 installed in the countersunk hole 561 and connected to the friction block 54. It should be noted that the movable plate 531 can move on the bolt 562 to ensure that the friction block 54 can move.

[0086] See attached Figure 1 — Figure 3 As shown, in the present application, a movable part 22 movably connected to the stator 1 is installed on the end cover 21. The movable part 22 can be a sleeve or a bearing, which can effectively reduce the friction of the stator 1 during rotation.

[0087] See attached Figure 6 — Figure 8 As shown, the present application also discloses a fire extinguishing device, including a nozzle 41 that rotates synchronously with the rotor and is connected to the medium channel 4, a connection terminal box 7, a fire-fighting motor, and a water inlet pipe 11 provided on the fire-fighting motor. The present application uses the nozzle 41 to spray the fire-extinguishing medium flowing in the medium channel 4 toward the fire source; the water inlet pipe 11 is provided to transport the external fire-extinguishing medium into the motor.

[0088] See attached Figure 6 — Figure 8 As shown, in this application, the fire extinguishing equipment also includes an up-and-down adjustment mechanism 8 mounted on the motor; a central control circuit board connected to the control circuit board 6 is mounted in the junction box 7; and a solenoid valve 12 connected to the central control circuit board is mounted on the water inlet pipe 11. In this application, the up-and-down adjustment mechanism 8 is configured to drive the nozzle 41 to rotate up and down, adjusting the angle between the nozzle 41 and the ground so that the nozzle 41 can be directed toward the fire source, spraying the fire extinguishing medium toward the fire source to perform the fire extinguishing operation; the solenoid valve 12 and the control circuit board 6 are connected via the central control circuit board to transmit signals; and the configuration of the solenoid valve 12 can control the flow of the fire extinguishing medium.

[0089] See attached Figure 6 — Figure 8As shown, in this application, when the rotor 2 drives the nozzle 41 to rotate, the motion trajectory of any point on the nozzle 41 forms a first plane. When the up-down adjustment mechanism 8 drives the nozzle 41 to rotate, the motion trajectory of any point on the nozzle 41 forms a second plane perpendicular to the first plane. Specifically, it can be the plane formed by the motion trajectory of the center point of the nozzle on the nozzle 41. This application increases the range of rotation of the nozzle 41 by arranging the planes formed by the two trajectories perpendicularly. That is, the rotor 2 drives the nozzle 41 to rotate on the first plane, while the up-down adjustment mechanism 8 drives the nozzle 41 to rotate on the second plane, ensuring that the nozzle 41 can be directed toward the source of the fire to extinguish the fire.

[0090] See attached Figure 6 — Figure 8 As shown, in this application, the upper and lower control mechanism 8 includes a bracket 80 mounted on the rotor 2, an adjustable power source 81 mounted on the bracket 80, a transmission structure 82 connected to the adjustable power source 81 and the nozzle 41, a connector 83 movably connected to the stator 1 and the nozzle 41, and a sensor 804 for sensing fire is installed at the bottom of the protective cover 801. In this application, when the rotor 2 rotates through the bracket 80, the adjustable power source 81, the transmission structure 82 and the nozzle 41 can be driven to rotate. The adjustable power source 81 can be a motor, the power source for rotating the nozzle 41, and the transmission structure 82 can transmit the power source output by the adjustable power source 81 to rotate the nozzle 41. The connector 83 in the present application is used to connect the stator 1 and the nozzle 41. The connector 83 can be a connecting hose, and both ends of the connecting hose adopt a movable connecting structure 84. The movable connecting structure 84 includes an outer ring groove 841 set on the outer ring of the stator 11, and an inner ring groove 842 set on the inner wall of the connecting hose of the connecting head. Spherical steel balls 843 are filled between the inner ring groove 842 and the outer ring groove 841. The steel balls 843 can be inserted through a process hole set on the connecting head. The process hole is connected to the inner ring groove 842, and the steel balls 843 can pass through the process hole. The steel balls 843 are loaded from the process hole. After it is filled, the process hole can be blocked. A top screw can be used to block it to form a rotatable connecting structure. In order to achieve sealing between the two, a rubber sealing ring 844 is provided between the connecting head and the stator below the movable joint structure 84.

[0091] It should be noted that the transmission mechanism 82 can be a gear drive, a belt drive or a gear reversing box, etc., and the sensor 804 can be a combination of one or more of a smoke sensor, a temperature sensor or a fire sensor. The sensor can detect fire signals using an infrared or ultraviolet composite detection method. The fire signal sends an instruction through the central control circuit board, and the instruction controls the action of the fire extinguisher. One path is connected to the motor power supply, and the fire extinguisher scans according to the fire signal, and there is signal feedback. The feedback signal is used to adjust the angle and working status of the fire extinguisher. The other signal is connected to the fire control alarm console. The fire control alarm console is equipped with two data synchronization functions, PC and APP, which can realize remote control. When the fire source is extinguished, the sensor 804 outputs a signal through the central control circuit board, closes the solenoid valve, stops the water discharge, stops the alarm signal, resets the fire extinguisher, and the entire fire extinguishing work is completed.

[0092] See attached Figure 6 — Figure 8 As shown, in the present application, a fixing member 13 is installed on the stator 1, and a fixing bracket 14 is installed on the top of the fixing member 13. The present application can fix the stator on the installation wall by the fixing member 13 and the fixing bracket 14.

[0093] To remotely monitor the status of fire extinguishing equipment, a communication module can be installed on the equipment. 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.

[0094] See attached Figure 1 — Figure 8 As shown, the working principle of this application is as follows: When a fire occurs, the sensor 804 senses the fire and sends a fire signal to the central control circuit board. The central control circuit board sends a signal to the control circuit board 6, causing the control circuit board 6 to control the rotor 2 to start rotating. The rotor 2 drives the nozzle 41 to rotate through the bracket 80. When the nozzle 41 rotates to the specified position, the central control circuit board sends a signal again to cause the control circuit board 6 to control the adjustment power source 81 to start. The adjustment power source 81 drives the nozzle 41 to rotate through the transmission structure 82, so that the nozzle 41 faces the fire. Then, a signal is sent through the central control circuit board to control the solenoid valve 12 to open. The fire extinguishing medium passes through the water inlet pipe 11, the medium channel 4 and the nozzle 41 in sequence, and is finally ejected from the nozzle 41 to extinguish the fire.

[0095] Example 2 See attached Figure 9As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, a rotation limiting structure 23 for limiting the rotation angle of the rotor is provided on the rotor and the mover, and the rotation limiting structure 23 includes a limiting protrusion 231 provided on the stator and a matching protrusion 232 provided on the rotor 2 corresponding to the limiting protrusion 231.

[0096] In this embodiment, the rotation angle of the rotor 2 is limited by the limiting protrusion 231 and the matching protrusion 232, ensuring that the rotor 2 can only perform a 360° reciprocating rotation in both directions, and ensuring that the rotor 2 does not rotate excessively.

[0097] Example 3 See attached Figure 10 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the rotating structure 23 also includes two proximity switches 233, which are installed on the end cover 21 and are symmetrically distributed about the connecting line between the center point of the stator 1 and the limiting protrusion 231, and when the rotor 2 rotates, it will drive the proximity switch 233 to move, and the proximity switch 233 will sense the contact and passage of the mating protrusion 232.

[0098] In this embodiment, the proximity switch 233 is set to send a signal before the mating protrusion 232 and the limiting protrusion 231 on the rotor 2 come into hard contact, providing a signal for the brake device 5 to brake the rotor 2, thereby reducing the impact force generated by the collision between the limiting protrusion 231 and the mating protrusion 232, and extending the service life of the stator 1 and the rotor 2.

[0099] Example 4 See attached Figure 11 — Figure 15 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, a protective cover 801 is installed on the bracket 80, and the protective cover 801 is provided with a spray hole 802, and a blocking member 803 corresponding to the spray hole 802 is installed on the nozzle 41, and when the nozzle 41 is adjusted up and down, the blocking member 803 will be driven to rotate synchronously.

[0100] In this embodiment, the protective cover 801 is used to protect the motor and the nozzle 41 to prevent external substances from directly hitting the motor or the nozzle 41; the setting of the ejection hole 802 ensures that the fire extinguishing medium can be ejected from the ejection hole 802 to extinguish the fire; the setting of the blocking member 803 is used to block impurities such as dust to prevent a large amount of dust from directly contacting the motor and affecting the service life of the motor.

[0101] See attached Figure 11 — Figure 15As shown, in this embodiment, the blocking member 803 includes a connecting plate 8031 ​​fixedly mounted on the nozzle 41 by welding or the like, and an arc-shaped baffle 8032 mounted on the connecting plate 8031 ​​, and the arc-shaped baffle 8032 corresponds to the ejection hole 41 .

[0102] In this embodiment, the connecting plate 8031 ​​is fixedly installed on the nozzle 41, so that when the nozzle 41 rotates, the arc baffle 8032 can be synchronously driven to rotate; the setting of the arc baffle 8032 is used to block the ejection hole 41, prevent dust from entering from the ejection hole 41, and reduce internal dust; it should be noted that the forward end of the arc baffle 8032 is provided with a slope, that is, the end of the arc baffle 8032 away from the nozzle 41 is provided with a slope, which can effectively prevent the arc baffle 8032 from interfering with the protective cover 801 during the rotation process; in short, when the fire extinguishing medium needs to be sprayed to extinguish the fire, the nozzle 41 will rotate, and at this time, the arc baffle 8032 will be driven to rotate synchronously, and at this time, the end of the arc baffle 8032 away from the nozzle 41 is the moving forward end.

[0103] See attached Figure 11 — Figure 15 As shown, in this embodiment, the orthographic projection of the nozzle 41 on the second plane and the orthographic projection of the connecting plate 8031 ​​on the second plane form an angle with the opening facing the arc-shaped baffle 8032; when the nozzle 41 is rotated to any angle, the orthographic projection of the nozzle on the second plane does not overlap with the orthographic projection of the connecting plate on the second plane, thereby ensuring that when the nozzle 41 sprays the fire extinguishing medium, the fire extinguishing medium will not hit the arc-shaped baffle 8032, ensuring that the fire extinguishing medium can be sprayed onto the fire source to extinguish the fire.

[0104] The above embodiments are intended to illustrate the present application, not to limit the present application. Any solution that is a simple transformation of the present application falls within the scope of protection of the present application.
