Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) swarm control and anti-interference, specifically to an anti-interference device for UAV swarm control. Background Technology

[0002] With the widespread application of multi-rotor and fixed-wing UAVs in civilian and military fields, single UAVs are gradually developing towards a clustered approach of "multi-UAV collaboration and formation operation". UAV clusters rely on distributed perception, collaborative decision-making and task allocation to improve mission efficiency and robustness. They are widely used in scenarios such as inspection, surveying and mapping, emergency communication, search and rescue and electronic reconnaissance. Their control usually relies on inter-aircraft communication, positioning information and command links from ground control stations.

[0003] Existing power amplifier heat dissipation devices mostly adopt a single air cooling method. Although the structure is simple, it is often difficult to remove the concentrated heat generated in time when operating at high power, which can easily lead to overheating of the power amplifier and thus affect its working stability and service life. Especially in the field operation scenario of UAV swarm, the fan needs to continuously draw air from the outside for heat dissipation. However, the external environment is often accompanied by humidity, water vapor, dust or sand. These impurities enter the heat dissipation shell with the airflow and can easily cause the components to become damp, accumulate dust or even be damaged, thereby greatly reducing the reliability of the device. Therefore, this application proposes a UAV swarm control anti-interference device. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-interference device for unmanned aerial vehicle (UAV) swarm control to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drone swarm control anti-interference device, comprising a heat dissipation shell, two radio frequency antennas detachably mounted on the upper end of the heat dissipation shell, a vent shroud fitted inside the heat dissipation shell, and a control board fixedly mounted thereon; two through holes are provided on the outer surface of the heat dissipation shell, each through hole is equipped with a cooling fan, which can extract the high-temperature air inside the shell during operation; heat-conducting fins are fixedly mounted on the inner end of the heat dissipation shell, and a power amplifier module is fixedly mounted on the inner end of the heat-conducting fins; the power amplifier module is connected to the control board via a wire; a heat dissipation box is fixedly mounted on the end of the vent shroud away from the heat dissipation shell; a water tank is fixedly mounted on the inner end of the vent shroud; and a cooling device for auxiliary heat dissipation is provided on the upper end of the water tank.

[0006] As a further embodiment of the present invention, the cooling device includes a negative pressure cylinder, which is fixedly installed at the upper end of the water tank. The bottom end of the heat-conducting fins is fixedly connected to a conductive shell, and the output end of the conductive shell is fixedly connected to a guide tube. The free end of the guide tube is fixedly connected to the upper end of the negative pressure cylinder. By setting a negative pressure cylinder at the upper end of the water tank and connecting the heat-conducting fins to the conductive shell and the guide tube in sequence, heat can be transferred quickly and the coolant can be circulated under negative pressure, thereby improving heat dissipation efficiency and preventing the power amplifier from experiencing performance degradation or damage due to local heat accumulation.

[0007] As a further embodiment of the present invention, a shape memory metal sheet is fixedly connected to the inner end of the conductive shell, and a conductive steel wire is fixedly connected to the end of the shape memory metal sheet. The conductive steel wire passes through the inside of the guide tube. A passive plug is sleeved on the inner end of the negative pressure cylinder. A push block passes through the inside of the passive plug, and the push block is fixedly connected to the conductive steel wire. By utilizing the thermal deformation of the shape memory metal sheet, the push block inside the passive plug is actuated by the conductive steel wire, thereby realizing automatic control of the coolant flow. It can respond to the temperature changes of the power amplifier module without additional electronic control devices, thereby improving the heat dissipation response speed and system reliability.

[0008] As a further embodiment of the present invention, a plurality of triangular blocks are slidably installed on the inner end of the passive plug. The triangular blocks are arranged in a ring shape, and the outer surface of the triangular blocks is in contact with the bottom end of the push block. When the push block moves downward, its downward pressure will push the triangular blocks to move away from the push block. A plurality of limiting plates are provided at the bottom end of the passive plug, and the limiting plates correspond to the triangular blocks. Because the triangular blocks are arranged in a ring shape and are in contact with the push block, the pressure can be evenly distributed and the triangular blocks can be moved when the push block is pressed down.

[0009] As a further embodiment of the present invention, a water pump is provided above the water tank, the output end of the water pump is fixedly connected to the water tank, and a return pipe and an outlet pipe are fixedly connected to the bottom end of the heat-conducting fins respectively. The end of the return pipe is connected to the input end of the water pump. The water pump drives the coolant to circulate between the outlet pipe, the heat-conducting fins and the return pipe, thereby achieving efficient liquid cooling of the heat-conducting fins.

[0010] As a further embodiment of the present invention, a water outlet cylinder is fixedly connected to the upper end of the water tank, a reversing cylinder is fixedly installed at the inner end of the vent hood, the reversing cylinder and the water outlet cylinder are connected by an auxiliary cylinder and connected to the water outlet pipe, and a diverter pipe is fixedly connected to the upper end of the water outlet cylinder. Through the connection structure of the water outlet cylinder, the reversing cylinder and the diverter pipe, the coolant can be reasonably divided and circulated in the system, ensuring the coolant flow direction is stable, improving the circulation efficiency of the heat dissipation system, and thus improving the overall heat dissipation effect.

[0011] As a further embodiment of the present invention, a movable tube is provided inside the reversing cylinder, and the movable tube is connected to the reversing cylinder by a guide spring. A water outlet plate is fixedly installed inside the auxiliary cylinder, and an isolation cover is provided at the inner end of the water outlet plate. The isolation cover is connected to the water outlet plate by an unlocking spring, and an unlocking block is fixedly installed on the outer surface of the movable tube.

[0012] As a further embodiment of the present invention, a sealing sleeve is fixedly installed at the inner end of the reversing cylinder, and the sealing sleeve is fitted on the outer surface of the movable tube. Two through holes are opened on the outer surface of the movable tube. The two through holes are staggered and are both located on the left side of the sealing sleeve. By setting staggered through holes on the outer surface of the movable tube and cooperating with the structural design of the sealing sleeve, the switching of coolant flow can be realized during the movement of the movable tube, effectively avoiding liquid leakage, and improving the reliability and sealing of the reversing switching.

[0013] As a further embodiment of the present invention, heat dissipation fins are fixedly installed inside the heat dissipation box. The heat dissipation fins are divided into upper and lower groups, located on the upper and lower sides of the heat dissipation box respectively. A heat conduction pipe is inserted inside the heat dissipation fins, with its input end connected to the diverter pipe and its output end connected to the commutator. Two air guide fans are fixedly installed inside the heat dissipation box. When the air guide fans are working, they can accelerate the air flow inside the heat dissipation box, thereby achieving efficient heat exchange.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. When the power amplifier module temperature rises, the memory metal sheet automatically deforms after being heated and drives the coolant to flow, so that the coolant circulates through the heat-conducting fins to achieve liquid cooling of the heat-conducting fins. Compared with the single air cooling method, it can effectively avoid the problem of insufficient heat dissipation when running at high power and ensure the stable operation of the power amplifier module. 2. When the device is in a humid, dry, or sandy environment, the cooling fan can be turned off and its air outlet can be blocked. The device can rely solely on the liquid cooling system for heat dissipation, thus preventing external air from carrying moisture, dust, or sand into the heat dissipation shell and improving the reliability and service life of the device in complex environments. 3. When using this invention, by removing the vent cover and setting both cooling fans to exhaust air outward, the air inside the heat sink can flow continuously, thereby effectively suppressing the temperature rise of the power amplifier module when it is operating at low power or for a long time, and improving the heat dissipation stability under low power conditions.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figures 1-4A drone swarm control anti-interference device includes a heat sink 1. Two radio frequency antennas 2 are detachably installed on the upper end of the heat sink 1 by bolts. A vent 4 is fitted on the inner end of the heat sink 1. A control board 103 is fixedly installed on the inner end of the heat sink 1 by bolts. The control board 103 includes modules such as a main control board, a power management board, and a radio frequency front-end board, which can work together to realize the anti-interference control function of the drone swarm. Two through holes are provided on the outer surface of the heat sink 1. A cooling fan 101 is installed in each through hole. During operation, it can draw out the high temperature air inside the heat sink 1, thereby achieving effective heat dissipation. Specifically, the outer surface of the control board 103 is attached to the inner wall of the heat sink 1 through a thermally conductive material, so that the heat generated by the control board 103 during operation can be directly transferred to the heat sink 1 through the thermally conductive material, and the heat is dissipated by the natural heat dissipation of the heat sink 1. Furthermore, the thermally conductive material can be a thermally conductive silicone sheet or a phase change thermally conductive pad. Its flexible structure can form a full fit between the control board 103 and the inner wall of the heat sink 1, reduce contact thermal resistance, improve thermal conductivity, and thus ensure that the control board 103 can maintain a stable operating temperature under high load conditions. In this embodiment, the vent 4 is slidably connected to the heat sink 1. By default, the vent 4 is located inside the heat sink 1. When in use, the vent 4 can be pulled out. When the cooling fan 101 is working, the ambient air will enter the interior of the heat sink 1 through the vent 4. At the same time, the sliding connection between the vent 4 and the heat sink 1 not only makes it easy to pull out or push back manually, but also allows the extension length of the vent 4 to be adjusted according to the heat dissipation requirements, thereby changing the airflow area. When the vent 4 is fully extended, it can significantly increase the air intake volume. Combined with the exhaust effect of the cooling fan 101, a stable air convection channel is formed, which effectively improves the heat dissipation efficiency.

[0019] A heat-conducting fin 102 is fixedly installed on the inner end of the heat sink 1 by bolts. A power amplifier module 107 is fixedly installed on the inner end of the heat-conducting fin 102 by bolts. The power amplifier module 107 is connected to the radio frequency antenna 2 by wires. The power amplifier module 107 is connected to the control board 103 by wires. A heat sink 3 is fixedly installed on the end of the vent 4 away from the heat sink 1. The heat sink 3 is equipped with a water cooling device. A water tank 201 is fixedly installed on the inner end of the vent 4 by bolts. When the power amplifier module 107 amplifies the signal, the transistor inside will generate a lot of heat. Therefore, it is necessary to carry out heat dissipation treatment. The water tank 201 is filled with coolant. A cooling device for auxiliary heat dissipation is provided on the upper end of the water tank 201.

[0020] Example 2: Please refer to Figures 3-7A drone swarm control anti-interference device, based on embodiment 1, includes a cooling device comprising a negative pressure cylinder 301, which is fixedly installed on the upper end of a water tank 201. A conductive shell 108 is fixedly connected to the bottom end of a heat-conducting fin 102. The conductive shell 108 is made of metal and has good thermal conductivity. A guide tube 109 is fixedly connected to the output end of the conductive shell 108, and the free end of the guide tube 109 is fixedly connected to the upper end of the negative pressure cylinder 301. A shape memory metal sheet 111 is fixedly connected to the inner end of the conductive shell 108. A conductive steel wire 110 is fixedly connected to the end of the shape memory metal sheet 111, and the conductive steel wire 110 passes through the inside of the guide tube 109. A passive plug 302 is sleeved on the inner end of the negative pressure cylinder 301. A push block 303 passes through the inside of the passive plug 302, and the push block 303 is fixedly connected to the conductive steel wire 110. Furthermore, the shape memory metal sheet 111 can be made of nickel-titanium alloy material. This material can undergo a reversible martensitic-austenitic phase transformation when heated, thereby producing a stable deformation at a preset temperature. The shape memory metal sheet 111 can continuously output thrust, causing the conductive steel wire 110 to move linearly along the inside of the guide tube 109.

[0021] like Figure 7 , Figure 8 As shown, specifically, multiple triangular blocks 308 are slidably installed on the inner end of the passive plug 302. The triangular blocks 308 are arranged in a ring. The outer surface of the triangular blocks 308 contacts the bottom end of the push block 303. When the push block 303 moves downward, its downward pressure will push the triangular blocks 308 to move away from the push block 303. Multiple limiting plates 305 are provided at the bottom end of the passive plug 302, and the limiting plates 305 correspond to the triangular blocks 308. In this embodiment, the limiting plate 305 and the passive plug 302 are connected by a passive spring 304. A limiting ring is fixedly installed at the inner end of the negative pressure cylinder 301. The limiting ring corresponds to the limiting plate 305. When the passive plug 302 moves downward until the limiting plate 305 contacts the limiting ring, the passive plug 302 continues to move downward, which will cause the limiting plate 305 to be subjected to the reverse force of the limiting ring, causing the limiting plate 305 to move towards the passive plug 302. A locking hole 306 is opened on the outer surface of the limiting plate 305, and a locking block 307 is fixedly welded to the outer surface of the triangular block 308. When the pusher 303 pushes the passive plug 302 downward through the triangular block 308, the locking block 307 remains in contact with the outer surface of the limiting plate 305. As the limiting plate 305 moves upward under the action of the limiting ring, the locking hole 306 rises synchronously until it is aligned with the locking block 307. At this time, due to the continuous downward pressure of the pusher 303 on the triangular block 308, the locking block 307 is immediately embedded in the locking hole 306. At this time, the pusher 303 continues to move downward. It is worth noting that the outer surface of the pusher 303 is fixedly connected to the limiting block, and the inner end of the passive plug 302 is provided with a limiting groove. The limiting block is set in the limiting groove, so that the pusher 303 can only move within a limited range. At the same time, the pusher 303 can continue to move a certain distance after the passive plug 302 stops moving. This not only ensures that the movement range of the pusher 303 is controlled and avoids excessive displacement that could damage the internal structure, but also provides additional stroke redundancy for the thermal deformation of the shape memory metal sheet 111, thereby ensuring that the fluid flow regulation action can still be completed under high temperature or high power conditions. Specifically, the outer surface of the push block 303 fits into the interior of the passive plug 302 to achieve a sealing effect. At the same time, the outer surface of the push block 303 is provided with multiple movable grooves. When the push block 303 moves upward, the movable grooves are exposed above the passive plug 302, so that the upper and lower spaces of the passive plug 302 are connected to each other through the movable grooves. When the push block 303 moves downward, the movable grooves are submerged inside the passive plug 302.

[0022] like Figure 3 , Figure 6 , Figure 9 As shown, a water pump 105 is installed above the water tank 201. The output end of the water pump 105 is fixedly connected to the water tank 201. A drive motor 106 is fixedly installed on the upper end of the water tank 201 by bolts. The output end of the drive motor 106 is fixedly connected to the impeller inside the water pump 105. A return pipe 104 and a water outlet pipe 203 are fixedly connected to the bottom end of the heat-conducting fins 102, respectively. Specifically, the heat-conducting fins 102 are hollow structures, and the coolant in the water outlet pipe 203 can... The water flows through the interior of the heat-conducting fins 102 and into the return pipe 104. The end of the return pipe 104 is connected to the input end of the water pump 105. The upper end of the water tank 201 is fixedly connected to the water outlet cylinder 202. The inner end of the vent hood 4 is fixedly installed with a reversing cylinder 206 by a clamp. The reversing cylinder 206 and the water outlet cylinder 202 are connected by an auxiliary cylinder 205. The reversing cylinder 206 is connected to the water outlet pipe 203. The upper end of the water outlet cylinder 202 is fixedly connected to a diversion pipe 204.

[0023] A movable tube 402 is installed inside the reversing cylinder 206, and the movable tube 402 is connected to the reversing cylinder 206 by a guide spring 403. A water outlet plate 407 is fixedly installed inside the auxiliary cylinder 205, and an isolation cover 405 is installed at the inner end of the water outlet plate 407. The isolation cover 405 is connected to the water outlet plate 407 by an unlocking spring 406. In the default state, the isolation cover 405 is kept separate from the water outlet plate 407 under the elastic force of the unlocking spring 406. In this embodiment, both the water outlet pipe 202 and the water tank 201 are made of metal. When air flows, the internal coolant is cooled. The water outlet pipe 203 and the return pipe 104 are both flexible hoses. A push rod 401 is installed inside the water outlet pipe 203. When the vent 4 retracts into the heat sink 1, the end of the push rod 401 contacts the inside of the heat sink 1. Then, the other end of the push rod 401 contacts the outer surface of the movable pipe 402. As the vent 4 retracts into the heat sink 1, the push rod 401 pushes the movable pipe 402 to move and compresses the guide spring 403.

[0024] An unlocking block 404 is fixedly installed on the outer surface of the movable pipe 402. The unlocking block 404 is triangular in shape. When the movable pipe 402 moves away from the outlet pipe 203, the outer surface of the unlocking block 404 contacts the isolation cover 405 and continues to move, pushing the isolation cover 405 to move, so that the outlet plate 407 is in a sealed state. A sealing sleeve 408 is fixedly installed on the inner end of the reversing cylinder 206, and the sealing sleeve 408 is fitted onto the outer surface of the movable tube 402. Two through holes 409 are formed on the outer surface of the movable tube 402. The two through holes 409 are staggered and both are located on the left side of the sealing sleeve 408 (e.g., ...). Figure 9 (as shown) When the movable tube 402 is pushed by the push rod 401, the two through holes 409 on the outer surface of the movable tube 402 are located on the left and right sides of the sealing sleeve 408, respectively, thereby connecting the left and right chambers of the sealing sleeve 408. It is worth noting that the diameter of the movable tube 402 is smaller than the diameter of the reversing cylinder 206.

[0025] like Figure 2 , Figure 6 , Figure 10As shown, heat dissipation fins 11 are fixedly installed inside the heat sink 3. The heat dissipation fins 11 are divided into two groups, located on the upper and lower sides of the heat sink 3 respectively. Heat conduction pipes 12 are installed inside the heat dissipation fins 11. The input end of the heat dissipation fins 11 is connected to the diverter pipe 204, and the output end is connected to the reversing cylinder 206. Two guide fans 13 are fixedly installed inside the heat sink 3 by bolts. When the guide fans 13 are working, they accelerate the airflow inside the heat sink 3, thereby achieving efficient heat exchange. Through the coordinated arrangement of the upper and lower heat dissipation fins 11 and the heat conduction pipes 12, a stable air convection channel can be formed, enhancing the uniform distribution of heat. The high-speed airflow of the guide fans 13 and the layout of the heat dissipation fins 11 work together to quickly conduct heat to the air outlet, significantly improving the overall heat dissipation efficiency.

[0026] The working principle of this invention is: When in use, when the device is in a low-power operating state, the vent 4 can be pulled out so that both cooling fans 101 are in the outward air extraction mode. When the power amplifier module 107 runs for a long time and generates heat, the heat is conducted to the heat-conducting fins 102. Since the air inside the heat sink 1 is constantly flowing at this time, the heat-conducting fins 102 can still effectively suppress the heat generated by the power amplifier module 107 during operation. When high power is required, the temperature of the power amplifier module 107 rises accordingly. The heat is transferred to the shape memory metal sheet 111 through the heat-conducting fins 102. The shape memory metal sheet 111 deforms when heated, and the pusher block 303 moves down through the conduction wire 110. The pusher block 303 pushes the passive plug 302 downward through the triangular block 308, which forces the coolant in the negative pressure cylinder 301 into the auxiliary cylinder 205 through the water tank 201 and the water outlet cylinder 202. The coolant finally flows into the heat-conducting fins 102 through the reversing cylinder 206 and the water outlet pipe 203, thus achieving effective cooling of them. After the temperature of the heat-conducting fin 102 drops, the shape memory metal sheet 111 gradually returns to its initial state and pulls the push block 303 upward through the conductive steel wire 110. At this time, the movable groove on the surface of the push block 303 is exposed above the passive plug 302, so that the upper and lower spaces of the passive plug 302 are connected, which does not affect its normal upward movement.

[0027] If the power amplifier module 107 is under high load, the vent cover 4 needs to be pushed back into the heat sink 1. At this time, the push rod 401 contacts the inner wall of the heat sink 1, pushing the movable tube 402 to move. The movable tube 402 drives the unlocking block 404 to contact the isolation cover 405 and continues to push its displacement, finally making the water outlet plate 407 in a sealed state. Then, the two through holes 409 are located on the left and right sides of the sealing sleeve 408 respectively, realizing the connection between the left and right chambers. When the two guide fans 13 are running, they can accelerate the airflow inside the heat exchange box 3, improving heat exchange efficiency. Simultaneously, the drive motor 106 drives the impeller inside the water pump 105 to rotate, propelling the coolant to circulate along the following path: water tank 201 → outlet pipe 202 → distributor pipe 204 → heat pipe 12 → reversing cylinder 206 → outlet pipe 203 → heat-conducting fins 102 → return pipe 104… This process is repeated, and then the two cooling fans 101 will switch to exhaust and ventilation modes respectively to enhance the heat dissipation effect of the heat sink 1. When the device is in a harsh weather environment, such as a humid, dry, or sandy environment, the two cooling fans 101 can be turned off and the air outlets of the cooling fans 101 can be blocked, relying solely on the water cooling device to dissipate heat.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
