Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to an unmanned firefighting helicopter. Background Art

[0002] With the acceleration of urbanization, high-rise buildings and dense transportation networks make it difficult for fire trucks to reach certain emergency scenes.

[0003] Today’s drones can quickly patrol over wide areas and take high-definition images, which helps rescuers more accurately understand the scope and extent of a disaster. Small helicopters can quickly enter a disaster site and provide closer observation and monitoring, so using both together can make rescue work more comprehensive and effective. Utility Model Content

[0004] The utility model aims to provide an unmanned firefighting helicopter which can reach the accident scene more quickly, shorten the rescue time and improve the rescue efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] An unmanned firefighting helicopter includes a drone body, support frames are arranged on both sides of the bottom of the drone body, cameras, intercoms and infrared thermal imagers are arranged on the outer surface of the drone body, a cross plate is installed on the bottom of the drone body through a rotating mechanism, fire extinguishers are arranged on the four sides of the upper surface of the cross plate, vertical poles are installed on the upper surface of the cross plate near the four sides, a pair of first clamping plates are installed on the top of the vertical poles through a fixing mechanism, the outer surfaces of the two first clamping plates are connected to connecting rods, and the ends of the two connecting rods are installed with second clamping plates. An electric push rod is installed on the lower surface of the drone body, and a pressure rod is installed at the end of the telescopic end of the electric push rod.

[0007] It can be seen that the setting of cameras and infrared thermal imagers can help firefighters quickly develop more effective rescue plans. Through the setting of walkie-talkies, they can communicate with trapped people, calm their emotions, and guide them to protect themselves, further strengthen cooperation with firefighters, and improve rescue efficiency and success rate. In addition, through the setting of fixing mechanisms, fire extinguishers can be fixed, and four fire extinguishers can be carried at the same time for aerial firefighting, further improving the success rate of rescue.

[0008] Furthermore, the fixing mechanism includes a mounting shell installed on the top of the vertical pole, and a threaded rod with a pair of reverse threads is rotatably installed inside the mounting shell. Nut seats are respectively installed on the two reverse threads of the threaded rod, and connecting blocks are installed on the outer surfaces of the two nut seats. The ends of the connecting blocks are connected to the first clamping plate.

[0009] When placing a fire extinguisher on the cross plate, first rotate the threaded rod counterclockwise. Due to the setting of the reverse thread, the two nut seats can be driven away from each other, and then the two first clamping plates are driven away from each other through the connecting action of the connecting block. Then, the fire extinguisher is placed on the cross plate and is located between the two first clamping plates. Then, the threaded rod is rotated clockwise to drive the two first clamping plates to move inward at the same time and clamp them on the outside of the fire extinguisher to achieve the purpose of fixing it. While fixing the fire extinguisher, the hose of the fire extinguisher is placed between the two second clamping plates. When the two first clamping plates clamp the fire extinguisher, the connecting action of the connecting rod can drive the two second clamping plates to clamp the hose to keep it at the spraying angle.

[0010] Furthermore, the rotating mechanism includes a rotating shaft rotatably installed on the lower surface of the drone body, and the end of the rotating shaft is connected to the upper surface of the cross plate, the outer surface of the rotating shaft is sleeved with a gear ring, the lower surface of the drone body is installed with a motor, the end of the motor output shaft is installed with a gear, and the gear is meshingly connected with the gear ring.

[0011] When a fire extinguisher has finished spraying, the motor can be started to drive the gear to rotate. Through the meshing relationship between the gear and the gear ring, the rotating shaft can be driven to rotate. The rotating shaft drives the cross plate to rotate ninety degrees, so that the next fire extinguisher can be rotated to the lower side of the pressure rod, and then the fire extinguishing operation can continue.

[0012] Furthermore, a rescue cabin is installed on the upper surface of the drone body through buckles, and lifting rings are installed at the four corners of the top of the rescue cabin.

[0013] When the trapped patient needs emergency rescue and loses the ability to move, firefighters can remove the rescue capsule, place the trapped patient into the rescue capsule, and then quickly install the rescue capsule on the drone body through buckles, so that the patient can be quickly transferred to the nearest hospital for rescue, thereby increasing the success rate of rescue. If the trapped person is at a high altitude, the rescue capsule can be lowered from a high altitude using a sling for rapid transfer.

[0014] Furthermore, a rubber pad is provided on the inner wall of the first clamping plate, and an anti-slip pattern is provided on the outer surface of the rubber pad.

[0015] The provision of the rubber pad and the anti-slip grooves can increase the friction between the first clamping plate and the fire extinguisher, thereby improving the fixing effect of the fire extinguisher.

[0016] Furthermore, positioning sleeves are installed on four sides of the upper surface of the cross plate, and the inner diameter of the positioning sleeves is matched with the outer diameter of the fire extinguisher.

[0017] By placing the fire extinguisher in the positioning sleeve, the purpose of rapid positioning can be achieved, and the fixing effect of the fire extinguisher can be further improved to prevent the fire extinguisher from falling at high altitudes. BRIEF DESCRIPTION OF THE DRAWINGS

An electric push rod 111 is installed on the lower surface of the drone body 100, and a pressure rod 112 is installed at the end of the telescopic end of the electric push rod 111.

[0027] By setting up the camera 102 and the infrared thermal imager 104, firefighters can quickly find the location and heat source of the fire, capture the heat distribution in different temperature areas, detect the heat of the human body, and help firefighters quickly locate the position of the trapped person in the fire, so as to help firefighters quickly formulate a more effective rescue plan. By setting up the intercom 103, they can talk with the trapped person, calm his emotions, and guide him to take self-protection measures, further strengthen the cooperation with the firefighters, and improve the rescue efficiency and success rate. Before the rescue, the four fire extinguishers 106 can be placed on the four sides of the upper surface of the cross plate 105 respectively, so that the fire extinguisher 106 is between the two first clamping plates 108, and the hose of the fire extinguisher 106 is placed between the two second clamping plates 110, and then the two first clamping plates 108 are driven close to each other by the fixing mechanism 200, and clamped in the extinguisher. The outside of the fire extinguisher 106, at the same time, through the connecting action of the connecting rod 109, the two second clamping plates 110 can be driven to clamp and fix the hose of the fire extinguisher 106 to keep it at the spraying angle, and then the lead seal is removed and the safety pin of the fire extinguisher 106 is pulled out. When the drone body 100 drives the fire extinguisher 106 to rise, by starting the electric push rod 111, its telescopic end drives the pressure rod 112 to descend, and presses down the pressure handle of the fire extinguisher 106, so as to achieve the purpose of fire extinguishing, and through the setting of the rotating mechanism 300, when one of the fire extinguishers 106 is used up, the cross plate 105 can be driven to rotate ninety degrees, and the other fire extinguisher 106 can be rotated to the bottom of the pressure rod 112, and then the pressure rod 112 can be used to press down the pressure handle to extinguish the fire, and the four fire extinguishers 106 are distributed on four sides, which can make the force of the drone body 100 uniform and improve the flight stability.

[0028] Specifically, the fixing mechanism 200 includes a mounting shell 201 mounted on the top of the vertical pole 107, a threaded rod 202 having a pair of reverse threads is rotatably mounted inside the mounting shell 201, nut seats 203 are respectively mounted on the two reverse threads of the threaded rod 202, and connecting blocks 204 are mounted on the outer surfaces of the two nut seats 203, and the ends of the connecting blocks 204 are connected to the first clamping plate 108. When placing the fire extinguisher 106 on the cross plate 105, the threaded rod 202 is first rotated counterclockwise. Due to the setting of the reverse threads, the two nut seats 203 can be driven away from each other, and then the two nut seats 203 can be driven to move away from each other through the connection of the connecting blocks 204. The first clamping plates 108 are moved away from each other, and the fire extinguisher 106 is then placed on the cross plate 105 and between the two first clamping plates 108. The threaded rod 202 is then rotated clockwise to drive the two first clamping plates 108 to approach inward at the same time and clamp them on the outside of the fire extinguisher 106 to achieve the purpose of fixing it. While fixing the fire extinguisher 106, the hose of the fire extinguisher 106 is placed between the two second clamping plates 110. When the two first clamping plates 108 clamp the fire extinguisher 106, the connecting action of the connecting rod 109 can drive the two second clamping plates 110 to clamp the hose to keep it at the spraying angle.

[0029] Specifically, the rotating mechanism 300 includes a rotating shaft 301 rotatably installed on the lower surface of the drone body 100, and the end of the rotating shaft 301 is connected to the upper surface of the cross plate 105, and the outer surface of the rotating shaft 301 is sleeved with a gear ring 302. A motor 303 is installed on the lower surface of the drone body 100, and a gear 304 is installed at the end of the output shaft of the motor 303. The gear 304 is meshed and connected with the gear ring 302. When a fire extinguisher 106 is sprayed, the motor 303 can be started to drive the gear 304 to rotate. Through the meshing relationship between the gear 304 and the gear ring 302, the rotating shaft 301 can be driven to rotate, and the cross plate 105 can be driven to rotate ninety degrees through the rotating shaft 301, so that the next fire extinguisher 106 can be rotated to the lower side of the pressure rod 112, and then the fire extinguishing operation can continue.

[0030] Specifically, a rescue cabin 400 is installed on the upper surface of the drone body 100 through buckles, and lifting rings 401 are installed at the four corners of the top of the rescue cabin 400. When the trapped patient needs emergency rescue and loses the ability to move, the firefighters can remove the rescue cabin 400, put the trapped patient into the rescue cabin 400, and then quickly install the rescue cabin 400 on the drone body 100 through buckles, so that the patient can be quickly transferred to the nearest hospital for rescue, thereby improving the success rate of rescue, and if the trapped person is at a high altitude, the rescue cabin 400 can be lowered from a high altitude by using a sling for rapid transfer.

[0031] Specifically, a rubber pad 500 is provided on the inner wall of the first clamping plate 108, and an anti-slip groove is provided on the outer surface of the rubber pad 500. The provision of the rubber pad 500 and the anti-slip groove can increase the friction between the first clamping plate 108 and the fire extinguisher 106, thereby improving the fixing effect of the fire extinguisher 106.
