Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) inspection technology, and in particular to a UAV inspection take-off and landing platform. Background Technology

[0002] In an automated drone inspection system, the take-off and landing platform is the core infrastructure for achieving unmanned operation. To ensure the cleanliness of the platform's take-off area and prevent debris such as leaves, dust, sand, and snow from affecting the drone's accurate landing and safety, existing technologies typically employ the following methods: First, an openable and closable protective cabin is installed on the platform, and the cabin cover is closed after the drone takes off to physically prevent debris from falling in. Second, active cleaning devices are installed inside or around the platform, such as rotating brushes or sweeping arms on the platform surface, or high-pressure airflow is used to clean the platform surface before and after the drone lands.

[0003] However, the aforementioned existing technical solutions all have obvious drawbacks. For the protective cabin solution, the opening and closing of the cabin door will delay the emergency response of the UAV and continuously consume the platform's precious power. As for active cleaning devices such as brushes and blowers, their cleaning effect is often poor for sticky foreign objects such as bird droppings and wet mud. Moreover, the cleaning devices themselves, such as brush bristles, need to be regularly maintained or replaced due to wear and contamination, otherwise secondary pollution may occur. In addition, the high-speed rotating brushes or strong airflow during the cleaning process also pose a potential collision and damage risk to the UAV's landing gear or fuselage. Therefore, the existing technologies generally face problems such as insufficient reliability, derivative risks, and limited environmental adaptability in cleaning debris from take-off and landing platforms. For this reason, we propose this utility model. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drone inspection take-off and landing platform includes a base shell with an open top surface. Two support plates are rotatably mounted on the top surface of the base shell. A cleaning structure for cleaning the two support plates is provided inside the base shell. The cleaning structure includes a movable tube rotatably mounted inside the base shell. A plurality of nozzles are fixedly connected to the outer circular wall of the movable tube and are evenly distributed along the length of the movable tube. An installation groove is provided inside the base shell. A rotating shaft on one side of each of the two support plates passes through one side of the inner wall of the base shell and extends into the installation groove. Two first gears are rotatably mounted inside the installation groove and are fixed to the rotating shafts on one side of each of the two support plates. A second gear is rotatably mounted inside the installation groove, and a rack meshes between the second gear and the two first gears.

[0007] As a further embodiment of this utility model, a connecting shaft is rotatably provided inside the mounting groove. The connecting shaft is fixed to the second gear. A first motor is provided on one side of the bottom shell, and a protective shell is fixed on one side of the bottom shell. The first motor is fixed inside the protective shell. A synchronous pulley is fixed to the output end of the first motor and one end of the connecting shaft. A synchronous belt meshes between the two synchronous pulleys.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This UAV inspection take-off and landing platform, through the design of its cleaning structure, uses a first motor to drive a synchronous transmission mechanism that rotates two support plates in opposite directions. This allows the dirty surface to be transferred into the bottom shell while the clean bottom surface is instantly converted into a take-off and landing platform, solving the problems of slow response and high energy consumption of the protective cabin solution. The second motor drives the movable pipe in conjunction with a high-pressure spray system to form a scanning rinsing, effectively removing stubborn stains and avoiding the risk of collision between the cleaning device and the UAV. Combined with the limit plate stabilizing support mechanism controlled by an electric push rod, and the rainwater self-collection function achieved by the collection bucket and filter screen, the overall take-off and landing platform has achieved a comprehensive improvement in cleaning efficiency, operational safety, and environmental adaptability.

[0022] Reference Figures 1-4A drone inspection take-off and landing platform includes a base shell 1 with an open top surface. Two support plates 2 are rotatably mounted on the top surface of the base shell 1. The interior of the base shell 1 is provided with a cleaning structure for cleaning the two support plates 2. The cleaning structure includes a movable tube 201 rotatably mounted inside the base shell 1. Several nozzles 202 are fixedly connected to the outer circular wall of the movable tube 201 and are evenly distributed along the length of the movable tube 201. An installation groove 203 is provided inside the base shell 1. The rotating shafts on one side of the two support plates 2 pass through one side of the inner wall of the base shell 1 and extend into the interior of the installation groove 203. Two first gears 204 are rotatably mounted inside the installation groove 203 and are fixed to the rotating shafts on one side of the two support plates 2 respectively. A second gear 205 is rotatably mounted inside the installation groove 203, and a rack 206 meshes between the second gear 205 and the two first gears 204.

[0023] In this embodiment, a connecting shaft 207 is rotatably mounted inside the mounting slot 203. The connecting shaft 207 is fixed to the second gear 205. A first motor 208 is mounted on one side of the bottom shell 1, and a protective shell 211 is fixed to one side of the bottom shell 1. The first motor 208 is fixed inside the protective shell 211. Synchronous pulleys 209 are fixed to the output end of the first motor 208 and one end of the connecting shaft 207. A synchronous belt 210 meshes between the two synchronous pulleys 209. When the two bearing plates 2 are horizontal, they are spliced ​​together to form the take-off and landing platform of the UAV. When the platform top... When debris appears on the surface, the first motor 208 drives the connecting shaft 207 to rotate through the synchronous pulley 209 and the synchronous belt 210. When the connecting shaft 207 rotates, it drives the two bearing plates 2 to rotate in opposite directions through the transmission of the second gear 205, two racks 206 and two first gears 204, causing the bearing plates 2 to flip over. The debris side flips over and faces the inside of the bottom shell 1. Several nozzles 202 on the movable pipe 201 spray high-pressure water to wash and clean the stubborn debris. After the bearing plate 2 flips over, its bottom surface faces upward, providing a clean platform for the drone to take off and land.

[0024] In this embodiment, a second motor 3 is fixed on one side of the bottom shell 1. The output end of the second motor 3 passes through one side of the bottom shell 1 and is fixed to one end of the movable tube 201. A water tank 301 is fixed on the inner bottom surface of the bottom shell 1. A booster pump 302 is fixed on the top surface of the water tank 301. The water outlet pipe of the booster pump 302 is fixed in connection with the movable tube 201. The booster pump 302 is a prior art technology. The water outlet pipe of the booster pump 302 is a flexible hose. The first motor 208 and the second motor 3 are both electrically connected to an external controller. The power required by the device can be provided by installing a battery (not shown in the figure) inside the bottom shell 1.

[0025] In this embodiment, a fixing groove 4 is provided on one side of the bottom shell 1. A limiting plate 401 is slidably arranged inside the fixing groove 4. An electric push rod 402 is fixed on one side of the inner wall of the fixing groove 4. One end of the electric push rod 402 is fixed to one side of the limiting plate 401. The electric push rod 402 is electrically connected to an external controller. When the support plate 2 is horizontal, the electric push rod 402 pushes the limiting plate 401 out a certain distance, so that the top surface of the limiting plate 401 is in contact with the bottom surface of the two horizontal support plates 2, thereby supporting the support plate 2 and ensuring the stability of the platform when the UAV takes off and lands.

[0026] In this embodiment, a collection hopper 5 is fixed on one side of the bottom shell 1, and a filter screen 501 is fixed inside the collection hopper 5. The collection hopper 5 is connected to the water tank 301. A discharge hole 502 is opened on one side of the inner wall of the bottom shell 1. A piston 503 is slidably inserted inside the discharge hole 502. In rainy weather, the collection hopper 5 collects rainwater into the water tank 301, reducing the frequency of water filling into the water tank 301. The filter screen 501 prevents debris from entering the water tank 301.

[0027] In this embodiment, both sides of the two support plates 2 are inclined surfaces, and the two support plates 2 are attached to each other on their sides. When the two support plates 2 are horizontally spliced ​​together, their inclined surfaces that are close to each other are attached, which can prevent the cleaning water in the bottom shell 1 from seeping into the top surface of the support plate 2.

[0028] Working principle: During use, when the operator cleans the top surface of the support plate 2 via external command, the platform first prepares to flip. The electric push rod 402, electrically connected to the external controller, retracts, driving the limit plate 401 to retract into the fixing groove 4, releasing the horizontal limit on the two support plates 2. Immediately afterwards, the first motor 208 starts, transmitting power to the connecting shaft 207 through a transmission system composed of a synchronous pulley 209 and a synchronous belt 210. The rotation of the connecting shaft 207 drives the second gear 205 on it to rotate. The five drives the two racks 206 meshing with it to move in a straight line. These two racks 206 in turn drive the two first gears 204 to rotate, and finally transmit the power precisely to the shaft on one side of the support plate 2. This transmission mechanism ensures that the two support plates 2 can be flipped downwards in a synchronous and smooth manner until their original top surfaces used for take-off and landing face downwards into the bottom shell 1. The attached debris is also brought into the cleaning station. At this time, the original clean bottom surface of the support plate 2 faces upwards, providing the drone with a clean take-off and landing platform that can be used immediately.

[0029] Subsequently, the cleaning process enters the core rinsing stage. The booster pump 302 draws water from the water tank 301 and pressurizes it into a high-pressure water flow, which is then delivered to the movable pipe 201 through a hose. At the same time, the second motor 3 starts, driving the movable pipe 201 to swing slowly. The high-pressure water flow is sprayed at high speed from several nozzles 202 that are evenly distributed along the length of the movable pipe 201, forming a scanning water curtain that covers the entire inner surface of the flipped support plate 2. Under the strong impact of the water flow, even stubborn debris can be completely removed.

[0030] After the rinsing operation is completed, the first motor 208 reverses and, through the aforementioned transmission mechanism, synchronously flips and resets the two bearing plates 2 to a horizontal state. To ensure stability during the lifting and lowering process, the electric push rod 402 moves again to push out the limiting plate 401, so that its top is tightly attached to the bottom surface of the two horizontal bearing plates 2, forming a reliable mechanical support. In rainy weather, the collection hopper 5 set on one side of the bottom shell 1 will automatically collect rainwater. After the rainwater flows through the filter screen 501 to filter out larger debris such as leaves, it is replenished into the water tank 301, effectively reducing the frequency of manual water addition.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
