Description

Technical Field

[0001] The present application relates to the field of drones, and in particular to a marine rescue drone. Background Art

[0002] Drowning has always been a major public safety issue worldwide. It occurs quickly, so drowning people need to be rescued in a timely manner. With the rapid development of drone technology, drones have demonstrated their unique advantages in many fields, especially in search, positioning, and delivery. The high maneuverability, flexibility, and remote control capabilities of drones give them huge application potential in the field of water rescue. At present, water rescue drones mainly include a drone body, a lifebuoy arranged on the drone body, and a driving mechanism that drives the lifebuoy out of the drone body. The lifebuoy part of the above-mentioned water rescue drone is a lifebuoy equipped with a carbon dioxide gas tank. When in use, the user is required to release the gas in the carbon dioxide gas tank to complete the inflation of the lifebuoy, resulting in unsatisfactory rescue efficiency. In view of the above-mentioned related technologies, the inventor believes that there is a need for a marine rescue drone with ideal rescue efficiency. Utility Model Content

[0003] In order to provide an ocean rescue drone with ideal rescue efficiency, the present application provides an ocean rescue drone.

[0004] The marine rescue drone provided in this application adopts the following technical solutions:

[0005] A marine rescue drone comprises a drone body and a rescue device; the rescue device comprises an installation box mounted on the bottom of the drone body, a rescue float sleeved on the outside of the installation box, an inflation mechanism mounted in the installation box and used to inflate the rescue float, and a downward drive mechanism for driving the rescue float to separate from the installation box.

[0006] By adopting the above technical solution, when carrying out rescue work, the operator first operates the ocean rescue drone to reach the position above the drowning person, inflates the rescue float installed outside the installation box through the inflation mechanism in the installation box, and then drives the inflated rescue float out of the installation box through the downward pressure drive mechanism, thereby sending the rescue float to the drowning person, providing a certain buoyancy for the drowning person, thereby achieving the purpose of efficient rescue.

[0007] Optionally, the rescue float has a float air nozzle for inflation and deflation; the inflation mechanism includes an inflation pin for cooperating with the float air nozzle, an inflation tank assembly for installing the inflation pin, and a sliding drive assembly for driving the inflation tank assembly to slide.

[0008] By adopting the above technical solution, the configuration of the float valve ensures that the rescue float will not leak during the inflation process and can maintain good working condition during long-term use. Driven by the sliding drive assembly, the inflation tank assembly slides toward the float valve, allowing the inflation pin to be inserted into the float valve to inflate the rescue float. When the rescue float is inflated, the sliding drive assembly drives the inflation tank assembly back to its original position, ending the inflation process of the rescue float, achieving a highly efficient inflation process for the rescue float.

[0009] Optionally, the sliding drive assembly includes a sliding platform for installing the air tank assembly, a first lead screw rotatably installed in the installation box, a first motor for driving the first lead screw to rotate, a first nut installed on the sliding platform and cooperating with the first lead screw, a first slide rail parallel to the first lead screw, and a first slider installed on the sliding platform and cooperating with the first slide rail, wherein the first lead screw is parallel to the sliding direction of the air tank assembly.

[0010] By adopting the above technical solution, the sliding of the air tank assembly is driven by the cooperation between the first screw, the first motor and the first nut, and the sliding of the air tank assembly is guided by the cooperation between the first slide rail and the first slider, thereby ensuring stable and precise sliding of the air tank assembly.

[0011] Optionally, the downward pressure drive mechanism includes a downward pressure piece vertically slidably installed on the installation box and a lifting drive assembly that drives the downward pressure piece to slide up and down; the downward pressure piece includes a downward pressure body and a downward pressure plate connected to the end of the downward pressure body, and the downward pressure plate is located on the upper side of the rescue float.

[0012] By adopting the above technical solution, the lower pressure piece is driven by the lifting drive assembly so that when the bottom surface of the lower pressure plate contacts the top surface of the rescue float, the lifting drive assembly continues to provide driving force, thereby separating the rescue float from the installation box, thereby achieving stable and reliable separation of the rescue float and the installation box.

[0013] Optionally, the pressing member horizontally passes through the two end side surfaces of the installation box, and the two ends of the pressing body are provided with the pressing plates; the installation box is provided with strip holes for the two ends of the pressing body to slide up and down.

[0014] By adopting this technical solution, the installation of pressure plates at both ends of the pressure body helps to improve the stability of the rescue float and reduce the probability of wear or failure of the pressure member due to uneven force during use. The provision of strip holes on the mounting box ensures that the pressure member can move smoothly and stably during the lifting process.

[0015] Optionally, the pressing body is connected to one end of the pressing plate, the other end of the pressing plate is provided with a guide protrusion, and the outer side wall of the mounting box is provided with a guide groove for the guide protrusion to slide up and down.

[0016] By adopting the above technical solution, the cooperation between the guide protrusion on the lower pressure plate and the guide groove on the installation box helps to provide guidance for the lifting and lowering of the lower pressure plate, ensuring that the lower pressure plate can stably push the rescue float out of the installation box.

[0017] Optionally, the lifting drive assembly includes a second screw rotatably installed in the mounting box, a second motor for driving the second screw to rotate, and a second nut installed on the pressing body and cooperating with the second screw, and the second screw is perpendicular to the sliding direction of the inflation tank assembly.

[0018] By adopting the above technical solution, the cooperation between the second screw, the second motor and the second nut helps to improve the stability of the lower pressure piece's lifting and lowering, and achieves precise lifting and lowering of the lower pressure piece.

[0019] Optionally, the bottom surface of the installation box is further provided with symmetrically arranged supporting base plates for supporting the bottom surface of the rescue float and a telescopic driving component for driving the two supporting base plates to slide relative to each other.

[0020] By adopting this technical solution, the support base plate and the telescopic drive assembly work together to ensure that when the rescue float is not inflated, the support base plate rests on the bottom of the float, providing support for the float. When the float is fully inflated, the support base plate retracts, facilitating the downward pressure of the drive mechanism. Precise sliding of the support base plate is achieved through the coordination of the bidirectional lead screw, the third electrode, the third nut, the second slide rail, and the second slider.

[0021] Optionally, a maintenance opening is provided at the bottom of the installation box and a mounting base plate for covering the maintenance opening is also installed; the supporting base plate and the telescopic drive assembly are both installed on the mounting base plate.

[0022] By adopting the above technical solution, the provision of a maintenance opening facilitates maintenance of the rescue device of the ocean rescue drone, ensuring the normal operation of the ocean rescue drone. The provision of the mounting base provides an installation platform for the support base and the telescopic drive assembly, helping to reduce the risk of seawater and other substances entering the installation box and affecting the normal operation of the rescue device.

[0023] Optionally, the top surface of the mounting box is provided with a mounting groove, and the bottom surface of the mounting groove is provided with a positioning groove; the drone body has a mounting slider that is slidably installed in the mounting groove, the top surface of the mounting slider is provided with a plunger hole and a ball head spring plunger is provided in the plunger hole, when the mounting box is installed on the drone body, the plunger ball head of the ball head spring plunger is clamped in the positioning groove.

[0024] By adopting the above technical solution, the installation box is installed on the drone body through the cooperation between the installation slider and the installation slide groove, and then the cooperation between the ball head spring plunger on the installation slider and the positioning groove on the installation slide groove helps to limit the installation box that is slidably installed on the drone body, thereby improving the stability of the installation box on the drone body and ensuring the normal operation of the ocean rescue drone.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. A marine rescue drone uses an inflation mechanism inside a mounting box to inflate a rescue float mounted outside the mounting box. A downward pressure actuator then drives the inflated rescue float out of the mounting box, allowing it to be delivered to the vicinity of a drowning person, achieving efficient rescue operations.

[0027] 2. By setting a guide protrusion on the lower pressing plate and setting a guide groove on the outer wall of the installation box for the guide protrusion to slide up and down, a guide is provided for the lifting and lowering of the lower pressing plate, which helps to ensure the stable movement of the lower pressing plate during the lifting process;

[0028] 3. A supporting base plate and a telescopic driving member that drives the supporting base plate to slide relative to each other are set on the bottom surface of the installation box, which helps to provide support force for the rescue float during inflation. When the rescue float is inflated, the support plate retracts, which helps the rescue float to detach from the installation box. BRIEF DESCRIPTION OF THE DRAWINGS
