Description

Technical Field

[0001] The present invention belongs to the technical field of port safety. More specifically, the present invention relates to a port fire warning and extinguishing system. Background Art

[0002] A port is a building facility established on the shore, which is the gathering point and hub of water and land transportation and plays an important role in transporting goods. In the yards, warehouses or working areas of combustible and flammable materials such as coal, wood, cotton, and hemp that are temporarily stored and transferred during port loading and unloading, fires are particularly likely to occur under the action of high temperature or fire sources. For small flames, it is safe and effective to use manual movable sprinkler heads to extinguish the fire source. When the fire source spreads rapidly and becomes larger, the manual fire extinguishing method not only causes casualties but also has low fire extinguishing efficiency. In this regard, the prior art discloses a drone for high-rise building fire fighting that can improve the fire extinguishing efficiency (publication number: CN107235147B), and also discloses a drone fire extinguishing device for marine port fires (publication number: CN112107814B), which lifts the fire hose and sprinkler head to the required position by the drone for fire extinguishing. Although it solves the safety problems of manual fire extinguishing and the reverse impact force of water flow, and improves the stability of drone fire extinguishing, the spread speed of fires in the yards, warehouses or working areas of combustible and flammable materials is very fast and the harmfulness is high. The fire extinguishing efficiency by spraying water with drones is still very limited. Timely locking of the ignition point, containing the fire and giving warnings are very important for reducing cargo losses and warning personnel to evacuate safely. Therefore, improvement is urgently needed. Summary of the Invention

[0025] In the above technical solution, a port fire warning and extinguishing system includes a fire monitor and a warning device 24 for real-time monitoring of areas required in the port, a unit positioning module formed in combination with the fire monitor, multiple groups of unmanned aerial vehicle (UAV) fire extinguishing devices, and a control module. The areas required in the port include open-air storage yards, warehouses or operating areas for temporarily storing combustible and flammable materials such as coal, wood, cotton, and hemp. The areas are divided into multiple square units as needed, and each unit corresponds to a group of the fire monitors for full-coverage monitoring. Each of the multiple square units can be set to the same size specification, which is convenient for subsequent monitoring and fire extinguishing, and also convenient for standardized management. Iron railings 25 are vertically fixed at the four corners of each square unit, and the fire monitor and the warning device 24 can be arranged on the top of the iron railings 25; the unit positioning module is used to obtain the position information of the unit where a fire occurs; multiple groups of UAV fire extinguishing devices are used to lift the fire hoses and the enclosure cloth 22 and fix them at preset positions of the iron railings 25; the control module is communicatively connected to the driving mechanisms of the unit positioning module, the warning device, and multiple groups of UAV fire extinguishing devices. The control module is used to control the operation of the multiple groups of UAV fire extinguishing devices according to the position information of the unit where a fire occurs obtained by the unit positioning module, lift the fire hoses and the enclosure cloth 22 around the unit where a fire occurs for enclosure, and control the corresponding warning device to issue an alarm; it can not only prevent the spread of flames but also block the influence of wind, improve the fire extinguishing efficiency, and reduce the losses caused by fires; wherein, the unit positioning module includes the fire monitor and a processing module. Each group of the fire monitors detects the flame, smoke, and temperature parameters of each unit in real time to determine whether a fire has occurred, and gives the judgment result to the processing module; when the judgment result is that no fire has occurred, the processing module records the information and waits for the reception of the next information; when the judgment result is that a fire has occurred, the processing module transmits the received judgment result and the corresponding unit position information to the control module.

[0026] The working principle and process of the present invention are as follows: When the fire monitor detects a fire in a certain unit, the unit positioning module sends fire information such as the location of the unit where the fire occurs to the control module. The control module controls the alarm to sound, the alarm lights of the fire unit flash, the broadcast reminds people to evacuate, and transmits the fire information to the fire control center, and starts the preparation work of the drone fire extinguishing device: First, connect the fire hose to the hose of the drone fire extinguishing device. Each enclosure cloth 22 is connected to a group of drone fire extinguishing devices. Control the double-headed motor 17 to reverse, so that the two clamping blocks 11 move away from each other and wait to be fixed at the preset position of the iron railing 25. After the preparation work is completed, through the control module, each group of drone fire extinguishing devices together with the fire hose and the enclosure cloth 22 are lifted to the preset position of the iron railing 25, so that the two mutually separated clamping blocks 11 are located on both sides of the iron railing 25 at the preset position. Control the double-headed motor 17 to rotate forward, so that the two clamping blocks 11 move closer to each other and clamp and fix with the iron railing 25, and enclose the enclosure cloth 22 between the two units, so that the periphery of the unit where the fire occurs is surrounded by the enclosure cloth 22, realizing the enclosure around the unit where the fire occurs. After the drone fire extinguishing device is fixed to the iron railing 25, open the water valve of the fire hose to let water through, and the water pipe nozzle of the drone fire extinguishing device can spray water on the fire in the fire unit to extinguish the fire, effectively preventing the spread of the fire, blocking the influence of the wind, improving the fire extinguishing efficiency, and reducing the losses caused by the fire.

[0027] On the basis of the above implementation, the drone fire extinguishing device includes a drone body 1. A lengthening rod 5 is fixedly connected to the bottom end of the drone body 1. A cantilever plate 7 is fixedly provided at the lower part of the lengthening rod 5. A double-headed motor 17 is installed at one end of the cantilever plate 7. The double-headed motor 17 controls two clamping blocks 11 to approach and move away from each other through a lead screw to clamp and release an iron railing 25, so as to realize the detachable fixation of the drone fire extinguishing device at a preset position of the iron railing 25. Further, a protrusion 28 can be provided at the preset position of the iron railing 25 to facilitate the fixed support of the drone fire extinguishing device at the preset position of the iron railing 25. The double-headed motor 17 controlling two clamping blocks 11 to approach and move away from each other through a lead screw can be realized by using the structure of the existing technology. The specific structure is as follows: The lead screw includes a first lead screw 16 and a second lead screw 18. One output end of the double-headed motor 17 is fixedly connected to the first lead screw 16. One end of a first clamping plate 14 is screwed on the circumferential outer wall of the first lead screw 16. The other output end of the double-headed motor 17 is fixedly connected to the second lead screw 18. One end of a second clamping plate 20 is screwed on the circumferential outer wall of the second lead screw 18. The thread spiral directions of the first lead screw 16 and the second lead screw 18 are opposite. The other ends of the first clamping plate 14 and the second clamping plate 20 are both fixedly connected with clamping blocks 11. Each clamping block 11 is in a semi-cylindrical shape. Through the semi-cylindrical shape, the situation of moving left and right between the clamping block 11 and the clamped iron railing 25 is reduced, achieving the effect of further improving the use stability. Anti-slip pads are fixedly connected to the inner walls of the clamping blocks 11. The anti-slip pads are rubber pads. Two limiting shafts 15 are fixedly provided on the cantilever plate 7. The two limiting shafts 15 are located on both sides of the cantilever plate 7 and are parallel to the first lead screw 16 and the second lead screw 18. The two limiting shafts 15 are respectively vertically and slidably connected to the middle parts of the first clamping plate 14 and the second clamping plate 20, so that the double-headed motor 17 controls two clamping blocks 11 to approach and move away from each other to clamp and release the iron railing 25. A first water pipe 2 is installed at the other end of the cantilever plate 7. One end of the first water pipe 2 is a pipe connection port for communicating with a fire hose. The other end of the first water pipe 2 is a nozzle. Among them, the cantilever plate 7 and the first water pipe 2 are connected through a swing mechanism 4. The swing mechanism 4 can specifically be an existing rotary cloud platform or a stepping motor. For example, when it is a stepping motor, the output shaft of the stepping motor can be vertically connected to the first water pipe 2, so as to control the rotation of the output shaft as needed to drive the nozzle to swing and adjust the water spraying direction. It further includes a suspension device, which includes a support rod 9 and a swing arm 13. The support rod 9 and the swing arm 13 are located on the same side of the clamping block 11. One end of the swing arm 13 is hinged to the outer side wall of the clamping block 11, and the hinge rotating shaft 12 is parallel to the support rod 9. The support rod 9 is in the same plane as the two clamping blocks 11 and perpendicular to the moving direction of the two clamping blocks 11. One end of the support rod 9 is fixedly connected to the cantilever plate 7, and the other end of the support rod 9 is provided with a through hole 10 adapted to the swing arm 13. When the swing arm 13 swings to be in the same plane as the support rod 9, the swing arm 13 and the through hole 10 are on the same straight line, so that when the two clamping blocks 11 move away from each other, the clamping block 11 can push the other end of the swing arm 13 close to the through hole 10 and penetrate into the through hole 10. When the two clamping blocks 11 move close to each other, the clamping block 11 can drive the other end of the swing arm 13 away from the through hole 10 and disengage from the through hole 10, so as to realize the hanging and separation of a plurality of hanging rings 21 on the side edge of the enclosure cloth 22 and the swing arm 13.

[0028] The design of the through hole 10 adapted to the swing arm 13 is specifically as follows: the through hole 10 is axially opened along the radial direction of the support rod 9, and the axial direction of the through hole 10 is parallel to the moving direction of the two clamping blocks 11. The through hole 10 is parallel and on the same straight line as the swing arm 13 when the swing arm 13 swings to the horizontal state. The aperture of the through hole 10 is slightly larger than the outer diameter of the swing arm 13, which is beneficial for the other end of the swing arm 13 to penetrate into the through hole 10, beneficial for a plurality of hanging rings 21 on the side edge of the enclosure cloth 22 to be hung on the swing arm 13, and beneficial for the folding and lowering of the enclosure cloth 22. A base 6 is fixedly provided below the cantilever plate 7, and a support leg 8 is fixedly provided below the base 6 for landing support of the UAV fire extinguishing device.

[0029] On the basis of the above implementation manner, the enclosure cloth 22 is a fireproof cloth or a flame retardant cloth. Connectors are provided on both sides of the upper end of the enclosure cloth 22 for detachably connecting to the outer side wall of the clamping block 11 or the upper end of the swing arm 13 of the corresponding group of UAV fire extinguishing devices. The specific design of the detachable connection between the connector and the upper end of the swing arm 13 can be: a plurality of screw holes 19 are provided on the upper end wall of the swing arm 13, and a corresponding plurality of screw holes 19 are also provided on the connector, and the connection is realized by screwing a screw into the screw holes 19 on the connector and the swing arm 13.

[0030] On the basis of the above implementation manner, it further includes a plurality of hanging rings 21, and the plurality of hanging rings 21 are equidistantly arranged on both side edges of the enclosure cloth 22. It is beneficial for the side edge of the enclosure cloth 22 to be hung on the swing arm 13 through a plurality of hanging rings 21, and beneficial for the folding and lowering of the enclosure cloth 22.

[0031] On the basis of the above implementation, a side wall interface 3 is provided on the side wall of the first water pipe 2. Third water pipes 26 and fourth water pipes 27 that are in communication with each other are respectively provided at the two sides and the bottom edge of the enclosure cloth 22. That is, the third water pipes 26 are located on the two sides of the enclosure cloth 22, and the fourth water pipes 27 are located at the bottom of the enclosure cloth 22. The upper end of the third water pipe 26 is communicated with one end of the second water pipe 23, and the other end of the second water pipe 23 is communicated with the first water pipe 2 through the side wall interface 3. This design is beneficial to the enclosure cloth 22 being lowered and having a firmer effect of blocking.

[0032] When a fire is detected in a certain unit, the control module controls the alarm to sound. The alarm lights of the fire unit flash, the broadcast reminds people to evacuate, and the fire information is transmitted to the fire control center. The drone fire extinguishing device is started for preparation: First, connect the fire hose to the first water pipe 2 of the drone fire extinguishing device. The connecting parts on both sides of the upper end of the enclosure cloth 22 are respectively connected to the outer side walls of the clamping blocks 11 of a group of drone fire extinguishing devices. A plurality of hanging rings 21 on both sides of the enclosure cloth 22 are respectively passed through the swing arms 13 of two drone fire extinguishing devices in sequence, so as to facilitate the folding of the enclosure cloth 22 up and down and facilitate the movement of the enclosure cloth 22 to the required position for lowering the enclosure. After the plurality of hanging rings 21 on both sides of the enclosure cloth 22 are passed through, when the swing arm 13 is swung to be in the same plane as the support rod 9 (that is, both are in a horizontal state), the swing arm 13 and the through hole 10 are in the same straight line. Control the double-headed motor 17 to reverse. During the process of the two clamping blocks 11 moving away from each other, the clamping block 11 pushes the other end of the swing arm 13 close to the through hole 10 and penetrates into the through hole 10, realizing the hanging of the plurality of hanging rings 21 on the side of the enclosure cloth 22 with the swing arm 13. Then, connect and fasten the other end of the second water pipe 23 of the enclosure cloth 22 to the first water pipe 2, that is, the enclosure cloth 22 and the water pipe are installed. Then, through the control module, each group of installed drone fire extinguishing devices is controlled to be lifted to the preset position of the iron railing 25, so that the openings of the two mutually separated clamping blocks 11 are inserted into the preset position of the iron railing 25 (that is, the two mutually separated clamping blocks 11 are located on both sides of the iron railing 25 at the preset position). Control the double-headed motor 17 to rotate forward. During the process of the two clamping blocks 11 approaching each other, while the two clamping blocks 11 are clamped and fixed to the iron railing 25, the clamping block 11 drives the other end of the swing arm 13 away from the through hole 10 and disengages from the through hole 10. The swing arm 13 disengaged from the through hole 10 swings downward under the action of gravity, and the plurality of hanging rings 21 hung on the swing arm 13 slide down and separate from the swing arm 13, so that the enclosure cloth 22 can be lowered and enclosed between the two units, realizing the enclosure around the unit where the fire occurs. After the drone fire extinguishing device is fixed to the iron railing 25, open the water valve of the fire hose to let water through. The nozzle of the first water pipe 2 of the drone fire extinguishing device can spray water on the fire of the fire unit. At the same time, the water pipes on both sides and the bottom of the enclosure cloth 22 become more rigid during the water filling process, improving the enclosure fire extinguishing effect, further effectively preventing the spread of the flame, blocking the influence of the wind, improving the fire extinguishing efficiency, and reducing the losses caused by the fire.

[0033] On the basis of the above implementation manner, a plurality of lateral branch water pipes (not shown in the figure) are arranged on the side of the enclosure cloth 22 that encloses the fire. The plurality of lateral branch water pipes are evenly distributed on the side of the enclosure cloth 22 that encloses the fire, and a plurality of water spraying holes facing the direction of the enclosed fire are formed on the plurality of lateral branch water pipes, the third water pipe 26 and the fourth water pipe 27. The plurality of lateral branch water pipes are communicated with the third water pipe 26. This design further improves the effect of preventing the spread of flames and is beneficial to improving the effect of surrounding and extinguishing the fire. The first water pipe 2, the second water pipe 23, the third water pipe 26, the fourth water pipe 27 and the lateral branch water pipes are all coated with fireproof cloth or flame retardant cloth to improve the temperature resistance and heat insulation effect.

[0034] On the basis of the above implementation manner, the fire monitor includes an image-type flame detector, a smoke detector or a temperature detector, and the warning device includes a flashing warning light, a broadcast and a communication module for transmitting to the fire control center; the enclosure cloth 22 further includes a plurality of magnetic blocks 29, and the plurality of magnetic blocks 29 are arranged at equal intervals on the two side edges of the enclosure cloth 22 and are arranged at intervals with the hanging rings 21. This design is beneficial to the magnetic connection between the enclosure cloth 22 and the iron railing 25 and improves the effect of surrounding and extinguishing the fire.

[0035] On the basis of the above implementation manner, a set of unmanned aerial vehicle fire extinguishing devices includes two unmanned aerial vehicle fire extinguishing devices. One unmanned aerial vehicle fire extinguishing device is fixedly connected to a connecting member on one side of the upper end of the enclosure cloth 22, and the other unmanned aerial vehicle fire extinguishing device is fixedly connected to a connecting member on the other side of the upper end of the enclosure cloth 22. A plurality of hanging rings 21 on both sides of the enclosure cloth 22 are respectively and sequentially passed through the swing arms 13 of the two unmanned aerial vehicle fire extinguishing devices, so that the enclosure cloth 22 can be folded up and down, which is beneficial to the lifting and lowering of the enclosure cloth 22, so that a set of unmanned aerial vehicle fire extinguishing devices can lift a piece of enclosure cloth 22 to a preset position of the iron railing 25 and fix it and lower the enclosure cloth 22, so that the enclosure cloth 22 surrounds one side of the fire-occurring unit to surround the four sides of the fire-occurring unit. During use, a set of unmanned aerial vehicle fire extinguishing devices can control the enclosure of one side of a unit, and four sets of unmanned aerial vehicle fire extinguishing devices can surround the four sides of a unit, lock the fire point in time, surround and extinguish the fire, prevent the spread of flames, and improve the fire extinguishing efficiency. If it is detected that fires occur in two adjacent units, the enclosure of the four sides of the two adjacent units can be controlled to surround and extinguish the fire.
