Description

Technical Field

[0001] The invention relates to the field of fire extinguishing, in particular to a low-temperature and antifreeze automatic fire extinguishing device. Background Art

[0002] Combustion requires three conditions: combustible material, combustion-supporting material, and an ignition source. Fire extinguishing aims to destroy existing combustion conditions. Removing just one of these conditions will extinguish the fire. Traditional fire extinguishing methods include cooling, suffocation, isolation, and suppression.

[0003] Publication number: CN113134183B discloses an automatic fire extinguishing device for substations, which relates to the technical field of fire-fighting equipment. Through an intelligent mobile vehicle that can plan its motion trajectory and a fire-fighting device arranged on the mobile vehicle, the mobile vehicle or the fire-fighting device is provided with an infrared temperature probe for detecting temperature. The automatic fire-fighting device can conduct patrol monitoring of the substation, solving the problem that the fire-fighting equipment currently used in substations is basically fixed, and the detection equipment used to detect fire points is also fixed. When a fire occurs, the fire source cannot be located and processed in the first time, thereby causing the fire to spread.

[0004] In the above-mentioned prior art, the automatic fire extinguishing equipment mainly extinguishes fires through the fire extinguishers it carries. However, when a fire occurs, since a group of automatic fire extinguishing equipment only carries one fire extinguisher, when the fire extinguishing material in the fire extinguisher is released, the fire extinguisher needs to be manually replaced. Moreover, when the fire expands, the automatic fire extinguishing equipment carrying fire extinguishers in the area has low fire extinguishing efficiency while extinguishing the fire, traveling back and forth, and replacing the fire extinguishers. For this reason, we have proposed a low-temperature and anti-freeze automatic fire extinguishing device. Summary of the Invention

[0014] Further: the movable mechanism includes an air pipe box, a motor B, a vent, a cylinder shaft, an air bleed pipe A, a spiral partition, an air bleed pipe B and a pipe sleeve. The motor B is installed at one end of the air pipe box, and the interior of the air pipe box is provided with an air vent connected to the fourth air hole. The output end of the motor B is fixedly connected to the axis of the cylinder shaft. One end of the air bleed pipe A and the air bleed pipe B are respectively installed at one end of the first air duct or the second air duct. The outer wall of the cylinder shaft is provided with a spiral partition. The air bleed pipe A is spirally coiled on the outer wall of the cylinder shaft through the spiral partition. One end of the air bleed pipe A and the air bleed pipe B are respectively sleeved.

[0015] Furthermore: the inflation channels at the corresponding positions of the fan blades and the disc are U-shaped, and the fan blades and the disc are separated from the rotating shaft by a fire extinguishing box.

[0016] Furthermore: a transverse opening adapted to the size of the vent pipe A is provided on the top of the tracheal box, and the inner wall of the tracheal box and the outer wall of the spiral partition are smooth surfaces.

[0019] Furthermore: a through pipe groove that is adapted to the size of the vent pipe A is opened on the upper surface of the drone landing gear from the edge to the lower side of the fire-fighting drone.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, when the fire extinguishing material in the gas storage chamber is consumed, the fire extinguishing device moves to the gas filling gun of the gas tank, and the fire extinguishing gas in the gas storage chamber can be quickly replenished through the filling mechanism. When a fire occurs, multiple fire extinguishing devices can automatically replenish and release fire extinguishing materials to automatically extinguish the fire;

[0022] 2. In the present invention, particularly during the inflation process, the second movable disc can isolate the pressure from the gas storage chamber from the first movable disc, so that the gas entering the inflation channel is not subjected to the reaction force of the gas pressure in the gas storage chamber. As the gas continues to enter the inflation channel, the dual effects of the continuous reciprocating motion of the first movable disc and the thrust of the spring can efficiently compress the gas through the second movable disc for use in the gas storage chamber. This can increase the inflation efficiency of the gas storage chamber and replenish as much fire extinguishing gas as possible in a short period of time, so that when a fire occurs, it can be promptly reduced and extinguished.

[0023] 3. In the present invention, the horizontal machine can move horizontally along the base on the mobile base, while the vertical machine can move longitudinally on the horizontal machine. Finally, the provided plane steering capability is used to expand the spray direction of the fire extinguisher. In the combination of the fire extinguisher and the fire-fighting drone, the fire extinguisher can cross obstacles and directly reach the fire site for effective fire extinguishing through the guidance of the air discharge pipe A by the fire-fighting drone. The air storage chamber inside the fire extinguisher solves the problem of traditional drone fire-fighting methods that are difficult to carry large amounts of fire extinguishing materials.

[0024] 4. When a fire occurs and the fire extinguishing device needs to operate for a long time, during the inflation process, the armature core can rotate with the disc through the transmission belt, and when the armature winding rotates inside the main magnetic pole, it can cut the magnetic flux lines and cooperate with the commutator and brushes to generate electricity to supply the device to improve the endurance. During the long fire extinguishing process, it provides additional power to the device and reduces the charging time, which can further improve the fire extinguishing efficiency.

[0025] 5. As the threaded shaft rotates, the ventilation pipe can move vertically inside the fire extinguisher. The ventilation pipe can switch between three modes: supplying air to the fourth air hole, the first air channel alone, or supplying air to all of them together through the first air hole, the second air hole, the third air hole, and the fourth air hole. That is, it can switch between the modes of near-point fire extinguishing, far-point fire extinguishing, and a combination of these modes. This allows the fire extinguishing device to flexibly switch between fire extinguishing modes when facing different fire situations.

[0026] 6. In the present invention, when the fire-fighting drone takes off, the cylinder shaft can be rotated by directly pulling the bleed pipe A to move a longer distance, or the cylinder shaft can be rotated by starting the motor B. By controlling the rotation direction of the cylinder shaft, the recovery or release of the bleed pipe A can be controlled. The setting of the spiral partition can separate multiple circles of the bleed pipe A to avoid mutual entanglement and squeezing that may cause poor gas circulation.

[0042] 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.

[0043] See also Figure 1-10, FIG is a preferred embodiment of the present invention, a low-temperature antifreeze automatic fire extinguishing device, comprising:

[0044] Mobile base 1, movable platform 2, fire extinguishing assembly 3 and inflation mechanism 4;

[0045] The movable platform 2 includes a base 21, and a horizontal machine 22, a vertical machine 23 and an electric turntable 24 are installed on the upper side of the base 21 in sequence from bottom to top; it can be understood that the horizontal machine 22 can move horizontally along the base 21 on the movable base 1, and the vertical machine 23 can move longitudinally on the horizontal machine 22, and finally cooperate with the provided plane steering capability to expand the spraying direction of the fire extinguisher 31.

[0046] The fire extinguishing assembly 3 is installed on the top of the electric turntable 24. The fire extinguishing assembly 3 includes a fire extinguishing box 31. A fire extinguishing drone 32 is provided on the upper side of the fire extinguishing box 31. A camera 33 is installed on the top of the fire extinguishing box 31 near the edge, and a gas storage chamber 34 is provided inside the camera 33. Among them, the fire extinguishing box 31 identifies the moving path through the camera 33 and observes whether there is a fire. In the combination of the fire extinguishing box 31 and the fire extinguishing drone 32, the fire extinguishing box 31 is guided by the fire extinguishing drone 32 to the vent pipe A75, so that when extinguishing a fire, it can cross obstacles and directly reach the fire site for effective fire extinguishing. The gas storage chamber 34 inside the fire extinguishing box 31 solves the problem that traditional drone fire extinguishing is difficult to obtain a large amount of fire extinguishing materials.

[0047] The inflation mechanism 4 includes an inflation channel 41, a fan blade 42, a disc 43, a movable rod 44, a first movable disc 45, a second movable disc 46, a guide rod 47, a spring 48 and a one-way valve cover 49. One end of the inflation channel 41 is provided on the back of the fire extinguisher 31 and the other end is connected to the gas storage chamber 34. The interior of the inflation channel 41 is rotatably connected to the fan blade 42. The axis of the fan blade 42 is fixedly connected to the disc 43 through a rotating shaft. The outer wall of the disc 43 is rotatably connected to the movable rod 44. The top of the movable rod 44 is rotatably connected to the At the lower end of the first movable disk 45, a second movable disk 46 is provided on the upper side of the first movable disk 45. Both the first movable disk 45 and the second movable disk 46 slide vertically inside the inflation channel 41. A guide rod 47 is fixedly connected to the inside of the inflation channel 41. The outer wall of the guide rod 47 is surrounded by a spring 48. The lower end of the spring 48 abuts against the upper end of the second movable disk 46. The upper surfaces of the first movable disk 45 and the second movable disk 46 are provided with a one-way valve cover 49, and the lower side of the one-way valve cover 49 is provided with a through opening.

[0048] It should be noted that the fire extinguishing gas inside the gas storage chamber 34 can be carbon dioxide. After the fire extinguishing material inside the fire extinguishing box 31 is consumed through the charging mechanism 4, the fire extinguishing gas inside the gas storage chamber 34 can be replenished through the charging gun on the gas tank after the device arrives at the designated location.

[0049] Among them, during the inflation process, especially when the air pressure in the container increases in the later stage, the reaction force on the subsequent filled gas becomes larger and larger, affecting the inflation efficiency. In the inflation mechanism 4, the gas injected by the air gun enters from the inflation channel 41, pushing the fan blade 42 to rotate and flow to the bottom of the first movable disk 45, and drills into the space between the first movable disk 45 and the second movable disk 46 from the opening on the surface of the first movable disk 45. When the fan blade 42 rotates, the movable rod 44 is driven by the disc 43 to move back and forth vertically on the lower side of the first movable disk 45, pushing the first movable disk 45 to move vertically in the inflation channel 41, so as to continuously send the gas between the first movable disk 45 and the second movable disk 46 from the opening of the second movable disk 46 into the air storage chamber 34. Since the second movable disk 46 moves along the guide rod 4 7 slides and the upper end of the second movable disk 46 is abutted by the spring, and the air pressure in the air storage chamber 34 pushes the second movable disk 46 to move downward. When the first movable disk 45 is lifted, the space between the first movable disk 45 and the second movable disk 46 is shortened, and the gas with increased pressure can pass through the second movable disk 46 from the gap to be used by the air storage chamber 34. The second movable disk 46 can isolate the pressure from the air storage chamber 34 for the first movable disk 45. In the process of gas continuously entering the inflation channel 41, the continuous reciprocating motion of the first movable disk 45 can efficiently pass the gas through the second movable disk 46 to be used by the air storage chamber 34, which can increase the inflation efficiency of the air storage chamber 34 and replenish as much fire extinguishing gas as possible in a short time, so that the fire can be reduced and extinguished in time when it occurs.

[0050] A charging mechanism 5 is provided on one side of the inflation mechanism 4, and the charging mechanism 5 includes a transmission belt 51, a main magnetic pole 52, an armature core 53 and an armature winding 54. One end of the transmission belt 51 is sleeved on the outer wall of the disc 43, and the main magnetic pole 52 is fixedly connected to the inside of the fire extinguisher box 31. The inner side of the main magnetic pole 52 is provided with an armature core 53, and the outer wall of the armature core 53 is installed with multiple armature windings 54. The other end of the transmission belt 51 is wound around the outer wall of the rotating shaft on one side of the armature core 53, and the armature core 53 is rotatably connected to the inner side of the main magnetic pole 52 through the transmission belt 51.

[0051] It can be understood that the armature core 53 can rotate with the disc 43 through the transmission belt 51, and when the armature winding 54 rotates inside the main magnetic pole 52, it can cut the magnetic lines of flux and cooperate with the commutator and brushes to generate electricity to supply the device to improve the endurance, provide additional power to the device during a long fire extinguishing process and reduce the charging time, which can further improve the fire extinguishing efficiency.

[0052] A ventilation mechanism 6 is provided inside the fire extinguisher box 31. The ventilation mechanism 6 includes a motor A61, a threaded shaft 62, a ventilation pipe 63, a first air hole 64, a second air hole 65, a third air hole 66, and a fourth air hole 67. The motor A61 is installed inside the fire extinguisher box 31. The output shaft of the motor A61 is fixedly connected to the threaded shaft 62. One end of the threaded shaft 62 is threadedly connected to the ventilation pipe 63. The ventilation pipe 63 is vertically slidably connected to the interior of the fire extinguisher box 31. The first air hole 64, the second air hole 65, the third air hole 66, and the fourth air hole 67 are respectively formed on both sides of the ventilation pipe 63.

[0053] A first air duct 68 and a second air duct 69 are respectively provided inside the fire extinguishing box 31. The first air duct 68 and the second air duct 69 are arranged on both sides of the ventilation pipe 63 and are respectively adapted to the first air hole 64, the second air hole 65 and the third air hole 66 and the fourth air hole 67.

[0054] Among them, it can be understood that after the motor A61 is started, as the threaded shaft 62 rotates, the ventilation pipe 63 can move vertically in the fire extinguisher box 31, and the ventilation pipe 63 passes through the first air hole 64, the second air hole 65, the third air hole 66, and the fourth air hole 67. It can switch between three groups of modes of supplying air to the fourth air hole 67 and the first air duct 68 separately or supplying air together, so as to facilitate the fire extinguishing device to flexibly switch the fire extinguishing mode when facing different fire conditions.

[0055] The movable mechanism 7 includes an air pipe box 71, a motor B72, an air vent 73, a cylindrical shaft 74, an air vent pipe A75, a spiral partition 76, an air vent pipe B77 and a pipe sleeve 78. The motor B72 is installed at one end of the air pipe box 71. The interior of the air pipe box 71 is provided with an air vent 73 connected to the fourth air hole 67. The output end of the motor B72 is fixedly connected to the axis of the cylindrical shaft 74. One end of the air vent pipe A75 and the air vent pipe B77 are respectively installed at one end of the first air channel 68 or the second air channel 69. The outer wall of the cylindrical shaft 74 is provided with a spiral partition 76. The air vent pipe A75 is spirally coiled around the outer wall of the cylindrical shaft 74 through the spiral partition 76. One end of the air vent pipe A75 and the air vent pipe B77 are respectively sleeved with a pipe sleeve 78.

[0056] It can be understood that one end of the bleed pipe A75 is connected to the inside of the cylinder shaft 74. Since the cylinder shaft 74 can rotate in the air pipe box 71, when the fire-fighting drone 32 takes off, it can either directly pull the bleed pipe A75 to rotate the cylinder shaft 74 to move a longer distance, or start the motor B72 to rotate the cylinder shaft 74. By controlling the rotation direction of the cylinder shaft 74, the recovery or release of the bleed pipe A75 can be controlled. Among them, the setting of the spiral partition 76 can separate multiple circles of the bleed pipe A75 to avoid mutual entanglement and squeezing that causes poor gas circulation, and the bleed pipe A75 is easy to recover.

[0057] The inflation channel 41 at the corresponding positions of the fan blade 42 and the disc 43 is U-shaped, and the fan blade 42 and the disc 43 are separated from the rotating shaft by the fire extinguishing box 31 so that the injected airflow can efficiently drive the fan blade 42 to rotate.

[0058] In order to make the movement of the vent pipe A75 smoother, a transverse opening that matches the size of the vent pipe A75 is opened on the top of the vent box 71, and the inner wall of the vent box 71 and the outer wall of the spiral partition 76 are smooth surfaces.

[0059] To facilitate the use of the device at night and to detect fires in a timely manner, the camera mode of camera 33 includes an infrared camera mode, which is convenient for monitoring temperature changes. A drone landing gear is installed on the top of the fire extinguishing box 31, which can cushion the impact force when the fire-fighting drone 32 is recovered.

[0060] Among them, one end of the vent pipe A75 is installed at the bottom of the fire-fighting drone 32. In order to adjust the spray angle of the vent pipe A75 or the vent pipe B77, a motor C is provided at the corresponding position of the pipe sleeve 78 at the bottom of the fire-fighting drone 32 and the inside of the fire extinguishing box 31. The output shaft of the motor C is fixedly connected to the middle of the outer wall of the pipe sleeve 78. The pipe sleeve 78 is rotated by the motor C at the bottom of the fire-fighting drone 32 or the inside of the fire extinguishing box 31. After the pipe sleeve 78 rotates, the direction of the vent pipe A75 or the vent pipe B77 is changed to change the spray position.

[0061] The upper surface of the drone landing gear is provided with a through pipe groove that is adapted to the size of the vent pipe A75 from the edge to the lower side of the fire-fighting drone 32.

[0062] It should be added that when the device is used in a low-temperature environment, the fire extinguishing gas used by the device, such as carbon dioxide, can be mixed with nitrogen. In the low-temperature environment, this prevents carbon dioxide from turning into solid dry ice and being unable to spray to extinguish the fire, making it easier to use the device in a low-temperature environment.

[0063] In this embodiment, when the device is used daily, the device patrols the production site through the mobile base 1, plans, analyzes and records the movement path through the camera 33, and checks whether there is a fire. When a fire point appears, the device moves to the vicinity of the fire point. When the fire point can be reached directly, the motor A61 starts to rotate the threaded shaft 62, controlling the fourth air hole 67 on the surface of the ventilation pipe 63 to communicate with the second air channel 69, and the gas is released from the exhaust pipe B77 and the angle is adjusted by the pipe sleeve 78 to extinguish the fire. The fire extinguishing box 31 is connected to the fire extinguishing device. In the human-machine 32 combination, the fire extinguisher 31 is guided by the fire-fighting drone 32 to the air release pipe A75. During fire extinguishing, the second air hole 65 is connected to the first air channel 68. The air release pipe A75, pulled by the fire-fighting drone 32, can traverse obstacles and directly reach the fire site for effective fire extinguishing. The horizontal platform 22 can move horizontally along the base 21 on the mobile base 1, while the vertical platform 23 can move longitudinally on the horizontal platform 22. Finally, the provided plane steering capability is used to expand the spray direction of the fire extinguisher 31.

[0064] During the fire extinguishing process, it should be noted that after the motor A61 is started, as the threaded shaft 62 rotates, the ventilation pipe 63 can move vertically in the fire extinguishing box 31, and the ventilation pipe 63 can switch between three groups of modes of supplying air to the fourth air hole 67 and the first air duct 68 separately or supplying air together through the first air hole 64, the second air hole 65, the third air hole 66, and the fourth air hole 67, so as to facilitate the fire extinguishing device to flexibly switch the fire extinguishing mode when facing different fire conditions.

[0065] After the internal gas is consumed, the fire extinguishing gas is replenished into the gas storage chamber 34 through the inflation gun at a fixed position after the device arrives at the designated location; during the inflation process, the gas injected by the air gun enters from the inflation channel 41, pushing the fan blades 42 to rotate and flow under the first movable disk 45, and drills into the space between the first movable disk 45 and the second movable disk 46 from the opening on the surface of the first movable disk 45. When the fan blades 42 rotate, the movable rod 44 is driven by the circular disc 43 to move back and forth vertically on the lower side of the first movable disk 45, pushing the first movable disk 45 to move vertically in the inflation channel 41, so as to continuously send the gas between the first movable disk 45 and the second movable disk 46 into the gas storage chamber 34 from the opening of the second movable disk 46. As the second movable disk 46 slides along the guide rod 47 The second movable disc 46 is moved and the upper end of the second movable disc 46 is abutted by a spring. The air pressure in the air storage chamber 34 pushes the second movable disc 46 downward. When the first movable disc 45 is lifted, the space between the first movable disc 45 and the second movable disc 46 is shortened, and the gas with increased pressure can pass through the second movable disc 46 from the gap to be used by the air storage chamber 34. The second movable disc 46 can isolate the pressure from the air storage chamber 34 for the first movable disc 45. In the process of gas continuously entering the inflation channel 41, the continuous reciprocating motion of the first movable disc 45 can efficiently pass the gas through the second movable disc 46 to be used by the air storage chamber 34, which can increase the inflation efficiency of the air storage chamber 34 and replenish as much fire extinguishing gas as possible in a short time, so that the fire can be reduced and extinguished in time when a fire occurs.

[0066] During the process, the armature core 53 can rotate along with the disc 43 through the transmission belt 51, and when the armature winding 54 rotates inside the main magnetic pole 52, it can cut the magnetic lines of force and cooperate with the commutator and brushes to generate electricity to supply the device to improve endurance.
