Description

Technical Field

[0001] The present invention relates to the field of drone fire extinguishing and fire fighting, and specifically refers to a fire extinguishing and fire fighting system based on drones. Background Art

[0002] In recent years, with the gradual development of drone technology, drones have been widely used in various fields, such as fire extinguishing and fire fighting. Conventional fire trucks are limited by environmental factors and cannot promptly extinguish the fire source. Therefore, a fire extinguishing and fire fighting system based on drones can effectively control the fire source in a timely manner.

[0003] However, the existing fire extinguishing and fire fighting systems cannot isolate the fire source from the air, preventing it from spreading or flowing to other places. As a result, the danger caused by the fire source cannot be instantly suppressed, and chain disasters triggered by the fire source cannot be prevented. Moreover, they cannot form multiple, continuous, and efficient fire extinguishing and fire fighting against the fire source.

[0004] Designing a fire extinguishing and fire fighting system based on drones to address the problems existing in the above-mentioned prior art is the objective of the research of the present invention. Summary of the Invention

Several one-way inlets are arranged on the fire blankets. During operation, the transport vehicle body drives close to the fire source point. Several of the hoisting drones are used to jointly clamp one of the fire blankets when the transport vehicle body drives close to the fire source point. Several of the hoisting drones are used to fly above the fire source after jointly clamping the fire blanket and then release the fire blanket to cover the fire source, so as to isolate the air outside the fire blanket from the fire source and prevent it from spreading or flowing to other places. The fire extinguishing drone is used to continuously spray a fire extinguishing agent on the outer surface of the fire blanket after several hoisting drones release the fire blanket to cover the fire source, so that the fire extinguishing agent opens and passes through the one-way inlet to enter the inner side of the fire blanket to extinguish the fire source.

[0007] Further, a storage compartment is provided on the transport vehicle body. An opening is provided on the top surface of the storage compartment. A bearing platform is provided in the storage compartment and below the opening.

Several fire extinguishing blankets are stacked on the top surface of the blanket lifting platform from bottom to top. A blanket lifting driving member is provided between the blanket lifting platform and the bearing platform. The width of the second lifting plate is smaller than the width of the blanket taking opening; The two heavy lifting unmanned aerial vehicles are used to successively jointly clamp the fire extinguishing blanket at the topmost of the blanket lifting platform according to the number of fire sources when the transport vehicle body travels close to the fire source point; The two heavy lifting unmanned aerial vehicles are used to fly above the fire source after jointly clamping the fire extinguishing blanket each time, and then release the fire extinguishing blanket to cover the fire source; the fire extinguishing unmanned aerial vehicle is used to continuously spray fire extinguishing agent on the outer surface of the fire extinguishing blanket after the two heavy lifting unmanned aerial vehicles release the fire extinguishing blanket to cover the fire source each time.

[0008] Further, an auxiliary member is provided between the blanket lifting platform and several fire extinguishing blankets; the auxiliary member is used to drive all the fire extinguishing blankets to be continuously unfolded and flat when there is a fire extinguishing blanket on the blanket lifting platform; the auxiliary member is used to limit all the fire extinguishing blankets at the same time when there is a fire extinguishing blanket on the blanket lifting platform, so as to prevent the several stacked fire extinguishing blankets on the blanket lifting platform from shifting during the driving of the transport vehicle body close to the fire source point, and to prevent the adjacent fire extinguishing blankets from shifting when the two heavy lifting unmanned aerial vehicles jointly clamp the fire extinguishing blanket at the topmost of the blanket lifting platform; The auxiliary member includes four auxiliary columns. The auxiliary columns are provided on the top surface of the blanket lifting platform and pass through several fire extinguishing blankets. The auxiliary columns are directly below the clamping mechanisms of the heavy lifting unmanned aerial vehicles.

[0009] Further, an anti-interference member is provided between the four auxiliary columns and the blanket lifting platform. The anti-interference member is used to drive the four auxiliary columns to descend a predetermined distance at the same time after the blanket lifting driving member drives the blanket lifting platform to rise a predetermined distance each time, so as to prevent the auxiliary columns from interfering with the clamping mechanisms of the heavy lifting unmanned aerial vehicles when the two heavy lifting unmanned aerial vehicles jointly clamp the fire extinguishing blanket at the topmost of the blanket lifting platform next time.

[0010] Further, the fire prevention component includes four brackets, which are arranged on the bottom end surface of the carpet lifting platform and below the auxiliary columns. Telescopic electric cylinders are arranged on the brackets. A through hole is arranged on the carpet lifting platform and below the auxiliary columns.

[0011] Further, the fire extinguishing blanket includes four sliding sleeves, which are slidably arranged on the auxiliary columns. A fire extinguishing blanket body is arranged between the four sliding sleeves. A micro check valve is arranged on the fire extinguishing blanket body and within the one-way inlet.

[0012] Further, four anti-involvement alignment components are arranged between the storage carriage and the bearing platform. The four anti-involvement alignment components are used to drive the bearing platform to rise above the opening during the process when two heavy-lifting drones jointly grab the fire extinguishing blanket at the top of the carpet lifting platform each time, so that the two heavy-lifting drones can directly drive the fire extinguishing blanket to fly above the fire source after jointly grabbing the fire extinguishing blanket at the top of the carpet lifting platform each time.

[0013] Further, a rotating cover is rotatably arranged on the storage carriage. The carpet lifting driving component includes an electric cylinder, which is arranged on the bottom end surface of the carpet lifting platform.

The chemical agent storage tank is communicated with the chemical agent pumping pump. The replenishing pipe of the chemical agent pumping pump is communicated with the fire extinguishing unit.

[0015] Therefore, the present invention provides the following effects and / or advantages: 1) During operation, the transport vehicle body travels close to the fire source point. A number of the heavy-lifting drones are used to jointly grab one of the fire extinguishing blankets when the transport vehicle body travels close to the fire source point. A number of the heavy-lifting drones are used to fly above the fire source after jointly grabbing the fire extinguishing blanket, and then release the fire extinguishing blanket to cover the fire source, so that the air between the fire source and the outer surface of the fire extinguishing blanket is isolated and cannot spread or flow to other places, thereby being able to instantly suppress the danger caused by the fire source and prevent the fire source from triggering a chain disaster. The fire extinguishing drone is used to continuously spray the fire extinguishing agent on the outer surface of the fire extinguishing blanket after a number of heavy-lifting drones release the fire extinguishing blanket to cover the fire source, so that the fire extinguishing agent opens and passes through the one-way inlet to enter the inner side of the fire extinguishing blanket to extinguish the fire source, thereby forming a multiple, continuous, and efficient fire extinguishing and firefighting for the fire source.

[0016] In summary, it can isolate the fire source from the air so that it cannot spread or flow to other places, thus instantly suppressing the danger caused by the fire source and preventing the fire source from triggering a chain disaster; it can form multiple, continuous, and efficient fire extinguishing and firefighting for the fire source.

[0017] 2) The storage carriage has a predetermined accommodation space. The storage carriage is used to carry components and store fire extinguishing drones, two heavy-lifting drones, and several fire blankets. The transport vehicle body is used to drive close to the fire source point to transport the fire extinguishing drones, two heavy-lifting drones, and several fire blankets stored in the storage carriage to a position close to the fire source point; the width of the second lifting plate is smaller than the width of the blanket-taking opening so that during the period when the two heavy-lifting drones are continuously supported by the second lifting plate, the front and rear clamping mechanisms of each heavy-lifting drone are located at the blanket-taking opening, enabling the two heavy-lifting drones to jointly clamp the fire blanket at the top of the blanket-lifting platform.

[0018] The two heavy-lifting drones are used to jointly clamp the fire blanket at the top of the blanket-lifting platform in sequence according to the number of fire sources when the transport vehicle body drives close to the fire source point.

[0019] The second lifting plate is used to continuously support the two heavy-lifting drones during each time the two heavy-lifting drones jointly clamp the fire blanket at the top of the blanket-lifting platform, enabling the two heavy-lifting drones to jointly clamp the fire blanket at the top of the blanket-lifting platform smoothly, precisely, and quickly each time, thus preventing the two heavy-lifting drones from clamping multiple fire blankets, causing the displacement or wrinkles of the fire blankets below when jointly clamping the fire blanket at the top of the blanket-lifting platform, shortening the fire extinguishing and firefighting preparation time for each fire source, and improving the fire extinguishing and firefighting efficiency for each fire source; The second lifting plate is used to be driven to move horizontally to the left after each time the two heavy-lifting drones jointly clamp the fire blanket at the top of the blanket-lifting platform until it is located on the left side of the blanket-taking opening, so as to make way after each time the two heavy-lifting drones jointly clamp the fire blanket at the top of the blanket-lifting platform and enable the fire blanket clamped jointly by the two heavy-lifting drones to pass through the blanket-taking opening and the opening in sequence; the horizontal movement driving member is used to drive the second lifting plate to act.

[0020] The two heavy-lifting drones are used to first drive the fire blanket to pass through the blanket-taking opening and the opening in sequence after jointly clamping the fire blanket each time, then drive the fire blanket to fly above the fire source, and then release the fire blanket to cover the fire source, so that the air between the fire source and the outer surface of the fire blanket is isolated and cannot spread or flow to other places, thus instantly suppressing the danger caused by the fire source and preventing the fire source from triggering a chain disaster.

[0021] The fire extinguishing drone is used to move along when the fire extinguishing blanket jointly clamped by two load-carrying drones passes through the blanket-taking port each time, and the fire extinguishing drone is used to move to one side of one of the load-carrying drones each time the two load-carrying drones drive the fire extinguishing blanket to fly above the fire source; The fire extinguishing drone is used to continuously spray fire extinguishing agent onto the outer surface of the fire extinguishing blanket after the two load-carrying drones release the fire extinguishing blanket to cover the fire source each time, so that the fire extinguishing agent opens and passes through the one-way inlet to enter the inner side of the fire extinguishing blanket to cool down and extinguish the fire source that has been air-isolated, thereby forming a multiple, continuous and efficient fire extinguishing and fire fighting for the fire source.

[0022] The blanket-lifting platform is used to be driven to rise a predetermined distance after the two load-carrying drones jointly clamp the fire extinguishing blanket at the top of the blanket-lifting platform each time, so that the two load-carrying drones can smoothly jointly clamp the fire extinguishing blanket at the top of the blanket-lifting platform the next time when continuously supported by the second lifting plate, thereby ensuring that the two load-carrying drones can successively jointly clamp the fire extinguishing blanket at the top of the blanket-lifting platform, so as to ensure that each fire source can be covered by the fire extinguishing blanket; the blanket-lifting driving part is used to drive the blanket-lifting platform to act.

[0023] To sum up: When approaching the fire source point, it can stably, accurately and quickly clamp the fire extinguishing blanket each time, so as to shorten the fire extinguishing and fire fighting preparation time for each fire source and improve the fire extinguishing and fire fighting efficiency for each fire source; it can make the fire extinguishing blanket cover the fire source, so that the air between the fire source and the outer surface of the fire extinguishing blanket is isolated and cannot spread or flow to other places, thereby instantly suppressing the danger caused by the fire source and preventing the fire source from triggering a chain disaster; after the fire source has been air-isolated, it can cool down and extinguish the fire, thereby forming a multiple, continuous and efficient fire extinguishing and fire fighting for the fire source.

[0024] 3) The auxiliary part is used to drive all the fire extinguishing blankets to be continuously in an unfolded and flat state when there is a fire extinguishing blanket on the blanket-lifting platform, so that the clamped fire extinguishing blanket is in an unfolded and flat state each time the two load-carrying drones jointly clamp the fire extinguishing blanket at the top of the blanket-lifting platform, thereby eliminating the need for the two load-carrying drones to adjust their positions in the air to make the clamped fire extinguishing blanket in an unfolded and flat state, so as to improve the stability, accuracy and speed of the two load-carrying drones jointly clamping the fire extinguishing blanket at the top of the blanket-lifting platform each time; The auxiliary part is used to limit all the fire blankets simultaneously when there is a fire blanket on the blanket lifting platform, so as to prevent the displacement of several stacked fire blankets on the blanket lifting platform during the driving of the transport vehicle body close to the fire source point, thereby preventing the need for manual adjustment of the position of the fire blanket when the two heavy-lifting drones initially jointly clamp the fire blanket at the top of the blanket lifting platform, resulting in the inability of the two heavy-lifting drones to clamp quickly, smoothly, accurately, and rapidly. It is also used to prevent the adjacent fire blankets from shifting when the two heavy-lifting drones jointly clamp the fire blanket at the top of the blanket lifting platform, thereby preventing the need for manual adjustment of the position of the fire blanket when the two heavy-lifting drones jointly clamp the fire blanket at the top of the blanket lifting platform next time, resulting in the inability of the two heavy-lifting drones to clamp quickly, smoothly, accurately, and rapidly.

[0025] 4) The anti-interference part is used to drive the four auxiliary columns to descend a predetermined distance simultaneously after the blanket lifting driving part drives the blanket lifting platform to rise a predetermined distance each time, so as to prevent the auxiliary columns from interfering with the clamping mechanism of the heavy-lifting drones when the two heavy-lifting drones jointly clamp the fire blanket at the top of the blanket lifting platform next time, thereby enabling the two heavy-lifting drones to clamp the fire blanket at the top of the blanket lifting platform smoothly, accurately, and rapidly each time.

[0026] 5) The four sliding sleeves are used to prevent the two heavy-lifting drones from damaging the main body of the fire blanket when clamping the fire blanket; the four sliding sleeves are used to increase the accuracy and speed of the fire blanket covering the fire source when the two heavy-lifting drones release the fire blanket to cover the fire source; the four sliding sleeves are used to reduce the displacement of the fire blanket that has already covered the fire source when the two heavy-lifting drones release the fire blanket to cover the fire source.

[0027] The micro check valve is used to enhance the air isolation degree between the fire source and the outer surface of the fire blanket after the fire blanket covers the fire source, preventing the spread or flow of the fire source to other places, thereby improving the ability to instantly suppress the danger caused by the fire source and preventing the fire source from triggering a chain disaster; the micro check valve is used to be opened by the fire extinguishing agent and allow the fire extinguishing agent to pass through and enter the inner side of the fire blanket to cool and extinguish the fire source that has been air-isolated, thereby forming a multiple, continuous, and efficient fire extinguishing and firefighting for the fire source.

[0028] 6) The four anti-interference and alignment parts are used to drive the bearing platform to rise above the opening during the process of the two heavy-lifting drones jointly clamping the fire blanket at the top of the blanket lifting platform each time, so that after the two heavy-lifting drones jointly clamp the fire blanket at the top of the blanket lifting platform each time, they can directly drive the fire blanket to fly above the fire source, thereby shortening the fire extinguishing and firefighting preparation time for each fire source again and preventing the fire blanket clamped jointly by the two heavy-lifting drones from interfering with the storage compartment.

The storage compartment 7 has a predetermined accommodation space. The storage compartment 7 is used to carry components. The storage compartment 7 is used to store the fire extinguishing drone 3, two hoisting drones 5, and a number of fire extinguishing blankets.
