Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a fire-fighting UAV with a rapidly replaceable water tank. Background Technology

[0002] Drone technology has developed relatively steadily, and many devices in various industries are moving towards drone technology. In the field of fire protection, using aerial water spraying to extinguish fires can effectively solve the problem of people being unable to enter the fire area, and can also replace firefighters in firefighting, thus improving the life protection of firefighters.

[0003] However, existing equipment does not have a drone water tank that can be quickly disassembled and assembled. The water tank is installed on the bottom of the drone with bolts. If the water source is insufficient and the water tank needs to be replaced, multiple fixing bolts need to be removed one by one, which reduces the efficiency of water tank replacement. Therefore, a fire-fighting drone with a water tank that can be quickly replaced is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fire-fighting drone with a rapidly replaceable water tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire-fighting drone with a quickly replaceable water tank, comprising a drone body, a connecting plate fixedly provided at the bottom of the drone body, an installation box fixedly provided at the bottom of the connecting plate, multiple springs fixedly provided at the bottom of the installation box, a common compression plate fixedly provided at the bottom of the multiple springs, a lifting structure provided inside the installation box, a vertical plate fixedly provided at the bottom of the lifting structure, a bearing plate fixedly provided on one side of the vertical plate, a horizontal fixing structure provided on the vertical plate, and a locking structure provided on one side of the vertical plate.

[0006] As a further description of the above technical solution:

[0007] The lifting structure includes two motors fixedly installed on the inner wall of the bottom of the mounting box and two sets of sliding rods fixedly installed on the bottom of the mounting box. The output end of the motor is fixedly provided with a threaded rod. The threaded rod passes through the inner wall of the bottom of the mounting box and extends to the outside of the mounting box. A sleeve is movably sleeved on the threaded rod. Two connecting pieces are fixedly provided on the outer wall of the sleeve. The two connecting pieces are movably connected to the two sliding rods respectively. The sleeve is fixedly connected to the top of the vertical plate.

[0008] As a further description of the above technical solution:

[0009] The connecting piece has a through hole, and a sealing ring is provided on the inner wall of the through hole. The inner wall of the sealing ring is movably connected to the slide rod.

[0010] As a further description of the above technical solution:

[0011] The horizontal fixing structure includes an adjusting screw that is movably connected to the vertical plate. One end of the adjusting screw is movably provided with a clamping plate, and the clamping plate is movably connected to the bearing plate.

[0012] As a further description of the above technical solution:

[0013] A guide block is fixedly provided on one side of the clamping plate, and a groove is provided on one side of the guide block. A bearing is fixedly provided in the groove, and the inner ring of the bearing is fixedly sleeved on the adjusting screw.

[0014] As a further description of the above technical solution:

[0015] The locking structure includes a limiting plate fixedly installed with the vertical plate, a locking frame movably provided on the limiting plate, and a pull handle fixedly provided on the top of the locking frame.

[0016] This utility model has the following beneficial effects:

[0017] 1. Compared with existing technologies, this fire-fighting drone with a quick-change water tank utilizes a lifting structure, springs, a pressing plate, and a horizontal fixing structure. When disassembling the water tank, the motor is activated, which drives a threaded rod. The threaded rod drives a sleeve, which in turn moves a vertical plate and a support plate, causing the water tank to move. Once the water tank is out of contact with the pressing plate, the adjusting screw is rotated counterclockwise. The adjusting screw then moves the clamping plate away from the water tank. When the two clamping plates are out of contact with the water tank, it can be removed. Installation is performed by reversing the process. This replaces the traditional bolt fixing method, simplifies the operation, and speeds up the replacement process.

[0018] 2. Compared with existing technologies, this fire-fighting drone with a quick-change water tank has a limit plate, a locking bracket, and a pull handle. The locking bracket can position the adjusting screw. After installation, the locking bracket is inserted into the limit plate and locked in the threaded groove of the adjusting screw. This can prevent the screw from rotating and causing the clamping plate to move, thus preventing the problem of unstable fixation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 4 This utility model provides a fire-fighting drone with a quickly replaceable water tank: It includes a drone body 1, a connecting plate 2 bolted to the bottom of the drone body 1, a mounting box 3 bolted to the bottom of the connecting plate 2, multiple springs 4 welded to the bottom of the mounting box 3, and a single compression plate 5 welded to the bottom of each spring 4. The mounting box 3 contains a lifting structure 6, which includes two motors 601 bolted to the inner wall of the bottom of the mounting box 3 and two sets of sliding rods 604 welded to the bottom of the mounting box 3. A threaded rod 602 is welded to the output end of each motor 601. The threaded rod 602 penetrates the bottom inner wall of the mounting box 3 and extends to the outside of the mounting box 3. A sleeve 603 is threaded on the threaded rod 602. Two connecting pieces 605 are welded to the outer wall of the sleeve 603. The two connecting pieces 605 are slidably connected to two sliding rods 604 respectively. The connecting pieces 605 are provided with through holes. A sealing ring is provided on the inner wall of the through holes. The inner wall of the sealing ring is slidably connected to the sliding rod 604. The sleeve 603 is welded to the top of the vertical plate 7. The lifting structure 6 can drive the vertical plate 7 and the bearing plate 8 to move. With the use of the top pressing plate 5, the longitudinal fixation of the water tank can be achieved.

[0027] A vertical plate 7 is welded to the bottom of the lifting structure 6. A bearing plate 8 is bolted to one side of the vertical plate 7. A horizontal fixing structure 10 is provided on the vertical plate 7. The horizontal fixing structure 10 includes an adjusting screw 101 threaded to the vertical plate 7. A clamping plate 102 is rotatably installed at one end of the adjusting screw 101. A guide block is welded to one side of the clamping plate 102. A groove is provided on one side of the guide block. A bearing is welded in the groove. The inner ring of the bearing is fixedly sleeved on the adjusting screw 101. The clamping plate 102 and the bearing plate 8 are slidably connected. The horizontal fixing structure 10 can realize the horizontal positioning of the water tank. A locking structure 9 is provided on one side of the vertical plate 7. The locking structure 9 includes a limiting plate 901 bolted to the vertical plate 7. A locking frame 902 is inserted into the limiting plate 901. A pull handle 903 is welded to the top of the locking frame 902. The locking structure 9 can lock the adjusting screw 101 to prevent the adjusting screw 101 from rotating and affecting the fixing effect.

[0028] Working principle: Motor 601 is a servo motor. When the water tank needs to be replaced, both motors 601 are started simultaneously and reversed. The two motors 601 drive the threaded rod 602, which in turn drives the sleeve 603 to move downwards. The sleeve 603 then drives the vertical plate 7 and the support plate 8 to move downwards. The support plate 8 then drives the top water tank to move downwards. When the top of the water tank is no longer in contact with the pressing plate 5, motor 601 is turned off. Then, the pull handle 903 is lifted upwards, which drives the locking frame 902 to move upwards. When the locking frame 902 disengages from the threaded groove of the adjusting screw 101, the adjusting screw 101 is rotated counterclockwise. The adjusting screw 101 then drives the clamping plate 102 to move away from the water tank. Once the two clamping plates 102 are no longer in contact with the water tank, the water tank can be removed. Then, place the new water tank on the top wall of the support plate 8 and start the motor 601 to rotate clockwise. The motor 601 drives the sleeve 603 through the threaded rod 602. The sleeve 603 pulls the vertical plate 7 upward. When the top of the water tank is in contact with the pressing plate 5, turn off the motor 601 and rotate the adjusting screw 101 clockwise. The adjusting screw 101 drives the clamping plate 102 to move. When the clamping plate 102 is in contact with one side of the water tank and clamps it, stop rotating the adjusting screw 101. Then, insert the locking bracket 902 into the limiting plate 901 so that the locking bracket 902 is inserted into the threaded groove of the adjusting screw 101, thus completing the replacement of the water tank.
