Description

Technical Field

[0001] This utility model relates to the field of high-pressure air cooling technology, and in particular to a high-pressure air cooling system for tethered unmanned aerial vehicles. Background Technology

[0002] Tethered drones are a special type of multi-rotor drone. Unlike traditional drones, tethered drones are connected to a ground base station via a high-strength tether cable and are continuously powered by a ground power source, thus enabling them to remain airborne for extended periods.

[0003] In existing technologies, drones are equipped with a large number of heat-generating components, which are mainly cooled by the downwash airflow generated by themselves. However, this cooling method has limited effectiveness, and using other methods would put a certain burden on the drone. Therefore, a high-pressure air cooling system for tethered drones is needed to meet people's needs. Utility Model Content

[0004] This invention addresses the technical problems existing in the prior art by providing a high-pressure air cooling system for tethered drones. This system solves the problem mentioned in the background art that the downdraft generated by the drone itself can dissipate heat, but this method has limited heat dissipation effect, while other methods would place a certain burden on the drone.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A high-pressure air cooling system for tethered drones includes a tethering box and a drone.

[0011] Preferably, the top of the tethering box has two movable doors that are slidably installed, and the two movable doors are compatible with each other.

[0012] The beneficial effects of this utility model are as follows: 1.

[0018] Reference Figure 1-5A high-pressure air cooling system for tethered unmanned aerial vehicles (UAVs) includes a tethering box 1 and a UAV 101.

[0019] After the activated carbon filter, drying components, and compressor produce clean, low-humidity, high-pressure gas on the ground, it is delivered to the aerodynamic vortex tube cooler on the drone through a delivery pipeline, thereby generating a low-temperature airflow. The heat inside the aerodynamic vortex tube cooler is carried away by the heat dissipation pipe passing through the body of the aerodynamic vortex tube cooler. The discharged cold and hot air are both guided to their own downwash air through the downward cold water pipe and hot air pipe.

[0020] In an optional embodiment: a pipeline storage compartment 3 is arranged inside the tethering box 1. A motor 301 is fixedly installed on the bottom side of the pipeline storage compartment 3. A telescopic rod 302 is fixedly installed at the output end of the motor 301. A telescopic rod 303 is fixedly installed at the output end of the telescopic rod 302. A traction sleeve 304 is fixedly installed at the output end of the telescopic rod 303. The traction sleeve 304 is adapted to the conveying pipeline 102.

[0021] It should be noted that the motor 301 can drive the telescopic rod 302 to rotate. The telescopic rod 302 and the telescopic rod 303 cooperate with the motor 301 to rotate, so that the conveying pipeline 102 can be circumferentially received and released within the conveying pipeline 102 in order to ensure that the conveying pipeline 102 can output at a uniform speed.

[0022] In an optional embodiment: an electric conveying roller 305 and a driven roller 306 are installed on the top of the pipeline storage compartment 3, both of which are in contact with the conveying pipeline 102.

[0023] It should be noted that the electric conveying roller 305 and the driven roller 306 are used to drive the conveying pipeline 102 to move up and down.

[0024] In an optional embodiment: a cylinder 307 is fixedly installed on the inner wall of the pipeline storage compartment 3, and the output end of the cylinder 307 is fixedly installed on the driven roller 306.

[0025] It should be noted that the cylinder 307 can control the clamping degree of the driven roller 306 below the conveying pipeline 102.

[0026] In an optional embodiment: a drone storage compartment 4 is provided on the top side of the tether box 1, and a lifting plate 401 is slidably installed inside the drone storage compartment 4. A through hole 402 is provided on the lifting plate 401, and the delivery pipeline 102 passes through the through hole 402.

[0027] It should be noted that the lifting cylinder 403 drives the lifting plate 401 to rise, moving the stored drone 101 to the outside of the tether box 1.

[0028] In an optional embodiment: a lifting cylinder 403 is fixedly installed on the bottom side of the drone storage compartment 4, and the output end of the lifting cylinder 403 is connected to the lifting plate 401.

[0029] In an optional embodiment, two movable doors 103 are slidably installed on the top of the tethering box 1, and the two movable doors 103 are compatible with each other.

[0030] It should be noted that the pipeline storage bin 3 and the drone storage bin 4 are used to collect the delivery pipeline 102 to prevent the delivery pipeline 102 from getting tangled during the rising or falling process and affecting the normal use of the device. At the same time, the lifting plate 401 is used to realize the active release and storage of the pneumatic vortex tube cooler 206, which strengthens the protection of the pneumatic vortex tube cooler 206 during transportation.

[0031] Working principle of this utility model: When using this device, the movable door 103 on the tether box 1 needs to be opened. Then, the lifting cylinder 403 drives the lifting plate 401 to rise, moving the stored drone 101 to the outside of the tether box 1. The user can then lift the drone 101. Most of the delivery pipeline 102 is stored in the pipeline storage compartment 3. The motor 301 is started, which drives the first telescopic rod 302 to rotate. The first telescopic rod 302 and the second telescopic rod 303 rotate in coordination with the motor 301, thus allowing the delivery pipeline 102 to be circularly stored and released within the delivery pipeline 102. To ensure that the delivery pipeline 102 can be output at a uniform speed, the electric delivery roller 305 and the driven roller 306 are used to drive the delivery pipeline 102 to rise and fall. The cylinder 307 can control the driven roller 306. Below the clamping degree of the delivery pipeline 102, inside the tethered box 1, the air is filtered using a filter screen 2 and an activated carbon filter element 201, then dried using a drying assembly 202, and finally compressed using a compressor 204 to produce clean, low-humidity high-pressure gas. The high-pressure gas flow enters the pneumatic vortex tube cooler 206 through the delivery pipeline 102, thereby generating hot and cold airflows, which are discharged through the cold water pipe 207 and the hot air pipe 208. The cold air enters the UAV 101 along with the pneumatic vortex tube cooler 206 to remove the heat generated during operation. At the same time, the discharged hot and cold air are guided to their own downwash air through the downward cold water pipe 207 and the hot air pipe 208 to reduce interference to the pneumatic vortex tube cooler 206.
