Description

If a fire occurs, it is very easy to form a chimney effect, and the fire will quickly spread from the lower floors to the higher floors. The use of fire-fighting equipment on the ground is limited: the water pressure is not enough, the fire hose is not easy to pull up to the floor where the fire occurs, and the ladder is slow to set up and it is difficult to reach the top floor. Therefore, it is difficult to extinguish fires in high-rise buildings. Firefighters climb high-rise buildings to extinguish fires on site, which is very likely to cause casualties and is very dangerous. At the same time, the roads along the way for fire trucks are often not smooth, and they are a certain distance apart. It takes a certain amount of time to arrive at the fire scene. Practice has proved that firefighting must race against time. Firefighting can only be effectively extinguished in the early stages of a fire.

After the dry powder fire extinguisher is used up, the device can fall to the ground to replace the dry powder fire extinguisher and put it into fire extinguishing again, which can make the fire extinguishing chain continue for a long time. The platform is rectangular with a remote control receiver installed on it and a PLC controller installed inside the rectangular body; the platform is equipped with batteries and other components except those installed outside the platform; two gas cylinders filled with compressed air are installed under the platform, and landing gear is installed under the gas cylinders; an air hammer nozzle assembly with a window breaking function is installed on the platform plane, and is fixed in the middle position of the longitudinal plane of the platform, with the axis direction being horizontal; the fire extinguishing bin assembly is installed on the platform, and a dry powder fire extinguisher is placed in the silo on its upper part, and the middle plane of the silo in the length direction coincides with the axis of the air hammer nozzle assembly, and the left and right sliders are installed in its slide box, with the V-shaped fork slider moving in the longitudinal direction; the installation position of the fire extinguishing bin assembly in the width direction must satisfy the requirement that the front end plane of the dry powder fire extinguisher in the fire extinguishing position fits with the powder inlet plane in the air hammer nozzle assembly, and the dry powder fire extinguisher stops here, which means that the fire extinguishing start position of the fire extinguisher is The axis and the hole of the air hammer nozzle assembly are coaxial and connected here, which is a clearance sliding fit, so that after the fire extinguishing is started, the dry powder is pushed by the high-pressure aerosol smoke and ejected from the fire extinguisher through the air hammer nozzle channel at high speed; the striker is used to impact the piezoelectric ceramic at the tail of the dry powder fire extinguisher to achieve ignition, so as to start the dry powder fire extinguisher to extinguish the fire, and the axis of the striker is coaxial with the axis of the dry powder fire extinguisher at the fire extinguishing start position; and a thrust fan is installed on each side of the middle of the platform in the longitudinal direction to generate dynamic thrust in the lateral direction to balance the axial reaction force during the impact window breaking and the dry powder fire extinguisher dry powder spraying fire extinguishing, the two thrust fans are symmetrically installed on both sides of the striker, and their axes are parallel to the axis of the striker; the two blades rotate in opposite directions, turn in opposite directions and have the same speed, and the speed is controlled by the inverter to obtain different dynamic thrusts; the arrangement and installation of these components in the platform are based on the static equilibrium position, and the inverter controls the speed of the thrust fan to achieve dynamic balance.

[0045] The fire extinguishing silo assembly includes: a silo, a slide seat, two left and right V-shaped fork sliders, and two left and right three-position cylinders; the silo is used to store dry powder fire extinguishers; two V-shaped fork sliders are symmetrically assembled on the longitudinal midplane of the slide seat, and the V-shaped fork sliders are pushed forward and extended along the slide in the slide seat under the push of the three-position cylinder to change the distance and positioning between the two V-shaped fork sliders, and the extension and retraction are respectively connected to compressed air pipes, which are connected to two two-position five-way solenoid valves through air pipes, and the P interface of the solenoid valve is connected to the gas cylinder, and the solenoid valve is electrically connected to the PLC controller; the pneumatic position is three positioning, the horizontal distance between the two V-shaped fork sliders A is medium, and the dry powder fire extinguisher can fall freely from top to bottom Entering the fire extinguishing starting position, the horizontal distance between the two V-shaped fork sliders in position B is the smallest, and the dry powder fire extinguisher is clamped and positioned in the slide seat from the outside to the inside. The horizontal distance between the two V-shaped fork sliders in position C is the largest. This position makes the dry powder fire extinguisher in the fire extinguishing position freely fall downward from the V-shaped fork slider after spraying dry powder and fall into the platform warehouse. Then the horizontal distance of the V-shaped fork slider is medium, and another dry powder fire extinguisher freely falls from top to bottom into the fire extinguishing starting position; the spatial depth of the dry powder fire extinguisher loaded in the fire extinguishing silo assembly is stacked vertically in a single row, and the toothed forks of the V-shaped fork slider are staggered on the left and right, which can clamp the dry powder fire extinguisher in the starting position at a small distance without interfering with the left and right V-shaped fork sliders.

[0046] The striker is a pneumatic part, including a striker head and a cylinder, which provides power for starting the piezoelectric ceramics in the dry powder fire extinguisher. Its extension and retraction are respectively connected to compressed air pipes, which are connected to a two-position five-way solenoid valve through an air pipe. The P interface of the solenoid valve is connected to the gas cylinder, and the solenoid valve is electrically connected to the PLC controller; the end face of the striker head is installed close to the piezoelectric ceramic button of the dry powder fire extinguisher in the fire extinguishing position, and is coaxial with the axis of the fire extinguishing nozzle and the air hammer assembly; its power is driven by the cylinder to impact and generate high-voltage electricity to ignite and start the dry powder fire extinguisher.

[0047] The air hammer nozzle assembly is a pneumatic part, including: an air hammer nozzle, a piston, a cylinder body, and a cylinder back barrel; two cylinder seats are installed and fixed on the platform, and the cylinder back barrel is fixed in the hole thereof, the cylinder back barrel is assembled with the cylinder body, and the air hammer nozzle is assembled with the piston; the holes at both ends of the cylinder body are sealed by sealing rings, and the inner hole of the cylinder back barrel and the outer barrel of the air hammer nozzle are slidingly matched; the air hammer nozzle repeatedly changes the axis running direction under the drive of compressed air to perform frequent window breaking operations; the air hammer nozzle and the piston extension and retraction air chambers are respectively connected to compressed air pipes on the cylinder body, and the pipes are connected to the AB ports of the two-position five-way solenoid valve through the air pipe, the P interface of the solenoid valve is connected to the gas cylinder, and the solenoid valve is electrically connected to the PLC controller.

[0048] Pneumatic process: Two gas cylinders are connected in parallel, and the switches of the two gas cylinders are controlled by PLC; the AB air pipes are connected to the air holes of the air hammer nozzle assembly and the three positioning air holes of the two parallel sliders and the cylinder air hole of the striker through the corresponding solenoid valves.

[0049] The power source in the above scheme is a hydrogen battery or a lithium battery, which is connected to a transformer, a rectifier, and a transmitter through a frequency discriminator: one route is connected to a PLC controller; the PLC controller switch is respectively connected to the solenoid valves of the gas cylinder, the fire extinguishing nozzle and the air hammer assembly, the slider, and the striker, and the PLC controller is respectively connected to the DA module to connect the frequency converter, the sensor of the fire extinguishing position of the dry powder fire extinguisher, the remote control, and the frequency converter connected to the thrust fan; the other route is connected to the remote control receiver power line, and the remote control receiver is respectively connected to the PLC controller I port, and controls the opening and speed of the thrust fan by connecting the frequency converter; there is also a PLC communication connection with a CCD camera; the two electrode wires of the piezoelectric ceramic are connected to the two wires of the electric ignition head in the dry powder fire extinguisher.

[0050] The dry powder fire extinguisher is equipped with a powder spray nozzle at the front, dry powder in the middle, an aerosol-generating agent at the bottom, and an electric ignition head at the bottom. It uses piezoelectric ceramics to generate electric sparks to start the aerosol agent to explode and generate 10MP air pressure to push the dry powder out of the nozzle for fire extinguishing. The piezoelectric ceramics are installed at the tail of the cylinder, and the movement direction of the piezoelectric ceramic button is coaxial and in the same direction as the axis of the cylinder, and the button extends out of the cylinder.

[0051] The control process of the above scheme is as follows: 1. Control of flying to the fire point: according to the navigation, the flight path is manually controlled to quickly and directly fly to the fire location, and then the fire extinguishing position is accurately located by video; 2. Window breaking control, the piston in the air hammer nozzle assembly is used to reciprocate in the cylinder body to link the air hammer to break the window; 3. Fire extinguishing control: PLC controller automatic control, according to the instantaneous video image and ranging data of the CCD camera, the automatic control content of the PLC controller includes: the accurate horizontal distance between the fire extinguishing device and the fire extinguishing wall, breaking the window, whether to start the next dry powder fire extinguisher according to the fire extinguishing effect, the piezoelectric ceramic of the striker hitting the dry powder fire extinguisher to start the fire extinguishing, the start and stop of the gas cylinder, and the automatic adjustment of the variable frequency speed to timely start the recoil fan and the variable frequency speed regulation to balance the reaction force; 4. According to the ground monitoring data and images, the remote control is manually adjusted to prioritize the adjustment and control of the window breaking point position, window breaking time, striker impact ignition and fire extinguishing related actions through the PLC; 5. The start and stop of the thrust fan, the balance of speed wind force and horizontal recoil force are automatically controlled by the PLC separate algorithm.

[0052] The robustness of the above scheme lies in that, when the UAV is hovering in the lateral direction, the speed adjustment of the thrust fan can achieve the following: 1. Balance the reaction force of window breaking, so that the air hammer nozzle assembly can be pulled out after the window is broken; 2. Avoid the air hammer nozzle head being stuck by the broken hole, affecting flight safety; 3. Balance the reaction force of dry powder fire extinguishing; this is achieved by the data collected by the CCD camera, which is accurately controlled and adjusted in time by the PLC controller, so that the UAV can be stable without being disturbed by the power of the fire extinguishing step.

[0053] Stop firefighting at any time without using other dry powder fire extinguishers that are not involved, so as to save firefighting costs; two or more devices are used, which are suitable for larger fires. If one dry powder fire extinguisher has used up all the dry powder during firefighting, it can immediately leave the fire scene, descend to the ground, unload the dry powder fire extinguisher that has used up all the dry powder, load a new dry powder fire extinguisher, and then another device will take over to continue firefighting. Subsequent equipment can continue to take over the rotation of firefighting, and the equipment that has completed the replacement and filling of dry powder fire extinguishers can join the rotation of firefighting again.

[0054] However, after analyzing the above scheme, its window breaking function needs to be close to high-rise buildings. The rising hot air flow generated during a fire and the strong lateral wind force of the high-rise building itself can easily interfere with the flight of the drone.

[0055] Another prior art provides a window-breaking fire-fighting drone, which includes a drone body connected to four rotating shafts, with rotatable propellers fixed above the rotating shafts to provide lift during flight. The drone body includes a retractable window-breaking device, and the bottom of the drone body is provided with a connecting shaft, which is used to connect the fuselage with a dry powder containing device.

[0056] The dry powder containing device includes a dry powder storage bottle and a dry powder spraying port. The thrust generated by the motor can realize the spraying of the dry powder in the dry powder bottle, so as to be used for fire extinguishing. The retractable window breaking device includes a telescopic rod and a window breaking head. The thrust and suction generated by the motor can control the extension and retraction of the telescopic rod, so as to be better used for fire extinguishing. The above-mentioned window-breaking drone fire extinguishing device can realize rapid fire extinguishing on high floors. The device has a simple structure and is easy to operate. Compared with traditional fire extinguishing devices, it not only has more functions, but also has a faster fire extinguishing effect, which greatly reduces the losses of high-rise fires. However, the above-mentioned device carries a limited amount of dry powder. When launching dry powder, the dry powder is easily affected by the airflow of the drone blades and cannot be accurately applied to the fire source, resulting in poor fire extinguishing effect.

[0057] Through the analysis of the above technology, an improved solution of the present invention is proposed.

[0058] 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.

[0059] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] A launching module, used to launch solid beads or dry powder fire extinguishing balls for breaking windows;

[0065] The conveying module is used to convey the solid beads or dry powder fire extinguishing balls for window breaking from the storage module to the launching module.

[0066] During use, the drone component 1 is equipped with the window breaking fire extinguishing component 5. When a high-rise fire occurs, the drone component 1 carries the window breaking fire extinguishing component 5 to a specified height and approaches the outer window of the high-rise building. The solid beads for window breaking are first provided through the storage module, and the conveying module is used to convey the solid beads for window breaking and load them into the launching module. The launching module fires the solid beads for window breaking to shatter the outer window of the high-rise building. Subsequently, the storage module conveys the dry powder fire extinguishing ball to the launching module through the conveying module, and the launching module launches the dry powder fire extinguishing ball to the fire source. After the dry powder fire extinguishing ball is thrown into the fire source, it explodes under the action of high temperature, and the dry powder inside it covers the fire source, thereby realizing the drone's high-altitude window breaking fire extinguishing operation.

[0067] As an optional embodiment of the present application, the storage module includes two storage bins 102 opened on the drone fuselage 101 of the drone assembly 1, one of which is used to store solid beads for window breaking, and the other is used to store dry powder fire extinguishing balls.

[0071] The machine arm 3 and the drone body 101 can be folded or telescopic to achieve the ability of convenient transportation.

[0072] The detailed structure and settings of the machine arm 3 and the control module 2 can be obtained through the existing technology, so they are not described in detail.

[0073] The bottom of the drone body 101 is equipped with a camera 4 through a gimbal. The camera 4 can be a binocular camera. The camera 4 can be a camera with thermal sensing shooting and ordinary shooting functions, which is convenient for finding the fire source and determining whether the fire source is covered. The camera 4 is an existing technology, so it is not described in detail.

[0074] At least two storage bins 102 are provided inside the drone body 101, wherein one storage bin 102 is used to store solid beads for window breaking, and the other storage bin 102 is used to store dry powder fire extinguishing balls. The size of the solid beads for window breaking is comparable to that of the dry powder fire extinguishing balls.

[0075] As an optional implementation of the present application, two storage bins 102 are respectively located on both sides of the conveying module.

[0076] The size of the solid beads for breaking windows is comparable to that of the dry powder fire extinguishing balls, and the balance of the drone body 101 can be ensured by adjusting the number of solid beads for breaking windows and the number of dry powder fire extinguishing balls.

[0077] As an optional embodiment of the present application, the conveying module includes:

[0078] The electromagnetic stator ring 504 is fixedly connected to the base 503. The two ends of the electromagnetic stator ring 504 are respectively fixedly connected with end covers 505. The end covers 505 are provided with a feed port 506 for feeding and a connecting hole 508 for discharging. The feed port 506 is connected with the discharging end of the feed pipe 502.

[0079] The loading wheel 509 is rotatably arranged in the electromagnetic stator ring 504, and the electromagnetic stator ring 504 is transmission-connected to the loading wheel 509. A plurality of material holes 510 circumferentially evenly spaced are provided on the loading wheel 509. The loading wheel 509 rotates so that the two ends of one of the material holes 510 are respectively connected to the two feed ports 506, and the two ends of another material hole 510 are respectively connected to the two connecting holes 508.

[0080] During operation, the electromagnetic stator ring 504 drives the loading wheel 509 to rotate, so that the material hole 510 opened on the loading wheel 509 switches between the connecting hole 508 and the feed port 506, and the solid beads for breaking windows or the dry powder fire extinguishing balls roll from the feed pipe 502 into one of the material holes 510. The loading wheel 509 rotates to move the material hole 510 between the two connecting holes 508 and connect them, so that the solid beads for breaking windows or the dry powder fire extinguishing balls are filled into the launching module.

[0081] As an optional implementation of the present application, the inner wall of the electromagnetic stator ring 504 is embedded with a plurality of electromagnetic sheets arranged at equal intervals in the circumferential direction, and the polarities of two adjacent electromagnetic sheets are opposite;

[0082] The side wall of the loading wheel 509 is embedded with a plurality of permanent magnets arranged at equal intervals in the circumferential direction, and the polarities of two adjacent permanent magnets are opposite;

[0083] When the electromagnetic sheet is energized, a magnetic field is generated and magnetically connected to the permanent magnet sheet.

When the magnetic field is generated, the electromagnetic sheet is magnetically connected to the permanent magnet sheet, and the loading wheel 509 can be driven to rotate under the magnetic effect. By switching the polarity of the electromagnetic sheet, the loading wheel 509 can be driven to rotate and its rotation angle and speed can be controlled.

[0085] A rotating shaft 511 is axially connected to the middle of the loading wheel disc 509 , and an end of the rotating shaft 511 is rotatably connected to the end cover 505 through a rotating shaft connecting hole 507 opened in the middle of the end cover 505 .

[0086] As an optional implementation mode of the present application, the transmitting module includes:

[0087] The gun barrel 501 is fixedly connected to one of the end covers 505, and one end of the gun barrel 501 is connected to the communication hole 508 of the corresponding end cover 505;

[0088] The air compression unit is fixedly connected to the bottom of the drone body 101 , and the air outlet of the air compression unit is connected to the connecting hole 508 of another end cover 505 .

[0089] During use, the loading wheel 509 rotates to connect one of the material holes 510 between the barrel 501 and the high-pressure air pipe 512. At this time, the high-pressure air stored in the high-pressure air pipe 512 will push the solid beads for breaking windows or the dry powder fire extinguishing balls to be ejected. When the loading wheel 509 rotates, its side wall is blocked at the air outlet end of the high-pressure air pipe 512. This is the inflation stage, and the internal air pressure is increased through the air compression part. As the barrel 501 is connected to one of the material holes 510, the air in the high-pressure air pipe 512 is gradually released and pushes the corresponding solid beads for breaking windows or the dry powder fire extinguishing balls to move, until the loading wheel 509 rotates to the material hole 510 and the barrel 501 are coaxial. The solid beads for breaking windows or the dry powder fire extinguishing balls are no longer limited by the side wall of the end cover 505, and the solid beads for breaking windows or the dry powder fire extinguishing balls are ejected through the barrel 501 at high speed under the action of air pressure.

[0090] As an optional embodiment of the present application, the air compression unit includes:

[0091] One end of the high-pressure air pipe 512 is fixedly connected to the corresponding end cover 505 , and the high-pressure air pipe 512 is connected to the corresponding connecting hole 508 . The other end of the high-pressure air pipe 512 is connected to an air compressor, and the fixed end of the air compressor is fixedly connected to the bottom of the UAV fuselage 101 .

[0092] As an optional embodiment of the present application, the air compressor includes an air pump housing 513, the top of the air pump housing 513 is fixedly connected to the bottom of the drone fuselage 101, and the bottom of the air pump housing 513 is connected to the high-pressure air pipe 512;

[0093] A piston 518 slides vertically in the air pump housing 513. The piston 518 divides the inner wall of the air pump housing 513 into an active chamber located at the top and a gas compression chamber 523 located at the bottom. The gas compression chamber 523 is connected to the outside through a one-way valve 522. The one-way valve 522 is used to allow external air to enter the gas compression chamber 523 when the piston 518 rises. A second one-way valve 524 is provided at the air inlet end of the high-pressure air pipe 512. The second one-way valve 524 is used to prevent the air in the high-pressure air pipe 512 from flowing back to the gas compression chamber 523 when the gas compression chamber 523 is in the inhalation stage.

[0094] The piston 518 is drivingly connected to a driving part for driving it to slide up and down.

[0095] As an optional embodiment of the present application, the driving unit includes a crankshaft 520, which is rotatably disposed in the air pump housing 513, one end of the crankshaft 520 is axially connected to the output end of the motor 519, and the fixed end of the motor 519 is fixedly connected to the outer wall of the air pump housing 513;

[0096] One end of a crankshaft connecting rod 521 is hingedly connected to the middle of the crankshaft 520 , and the other end of the crankshaft connecting rod 521 is hingedly connected to the piston 518 .

[0097] The crankshaft 520 is driven to rotate by the motor 519, and the piston 518 slides up and down under the cooperation of the crankshaft 520 and the crankshaft connecting rod 521. When the piston 518 rises, the one-way valve 522 serves as the air inlet end to supply air to the gas compression chamber 523. When the piston 518 descends, the second one-way valve 524 serves as the air outlet end to supply air to the high-pressure air pipe 512. Since the gas flow direction is restricted by the one-way valve 522 and the second one-way valve 524, the air pressure in the high-pressure air pipe 512 will continue to increase with the reciprocating motion of the piston 518.

[0098] As an optional embodiment of the present application, a limiting slide 514 is provided at the discharge end of the feed pipe 502, and a slider 515 is slidably connected to the top of the limiting slide 514, and one end of a spring 516 is fixedly connected to the bottom of the slider 515, and the other end of the spring 516 is fixedly connected to an electromagnet 517, and the electromagnet 517 is fixedly connected to the bottom of the limiting slide 514. The electromagnet 517 is magnetically connected to the slider 515, and when the electromagnet 517 is started, it attracts the slider 515 to compress the spring 516, and the top of the slider 515 is located on the inner side of the top of the limiting slide 514. When the electromagnet 517 is closed, the spring 516 is released, so that the top of the slider 515 is located on the outer side of the top of the limiting slide 514, so as to prevent the solid beads or dry powder fire extinguishing balls for breaking windows from rolling.

[0099] By making the top of the slider 515 located outside the top of the limiting slide 514, the rolling of the solid beads for window breaking or the dry powder fire extinguishing ball can be hindered. When the solid beads for window breaking are needed to be launched, the electromagnet 517 in the feeding pipe 502 on the side for conveying the solid beads for window breaking is started, and the spring 516 is compressed when the slider 515 is attracted, while the electromagnet 517 in the feeding pipe 502 for conveying the dry powder fire extinguishing ball is in a closed state, thereby preventing the dry powder fire extinguishing ball from entering the material hole 510. Conversely, when the window breaking is completed, the state of the total electromagnet 517 of the two feeding pipes 502 is switched to stop conveying the solid beads for window breaking and start conveying the dry powder fire extinguishing ball.
