Description

Technical Field

[0001] The present invention relates to the technical field of water quality remote sensing, and in particular to a water quality remote sensing measurement device. Background Art

[0002] Remote sensing of water quality refers to a modern technology that uses the infrared, ultraviolet, or fluorescent characteristics of pollutants, using remote sensing instruments such as aircraft, aerospace laboratories, and Earth satellites, to monitor the pollution status of rivers, lakes, reservoirs, and oceans. This technology is continuous and rapid, capable of determining the overall distribution of water pollution and the location of pollution sources, providing information on water pollution status over large areas or inaccessible areas. Monitoring targets primarily include oil pollution on the water surface, suspended solids in water, industrial wastewater, power plant cooling water, and algae blooms such as red tides.

[0003] Water pollution remote sensing uses the reflection properties of light waves and electromagnetic waves of substances in water, as well as the thermal radiation properties of the substances themselves to detect substances floating on the water surface and suspended in the water body, as well as certain compounds dissolved in water. Chemical pollutants can be detected by their fluorescence properties, and suspended substances in water can be detected by light absorption technology.

[0004] Existing technologies, such as the patent application with publication number CN111044329A, disclose a multi-depth water quality monitoring device based on satellite remote sensing. The device is connected to an external power supply for easy power supply. The electrical equipment of the device is controlled by an external controller. The detection signal is transmitted via satellite, and the device can be remotely controlled and the detection results can be viewed. The water area is remotely monitored through satellite remote sensing technology. When the satellite captures pollution in a certain water area, the operation of the device is remotely controlled.

[0005] Existing water quality remote sensing requires the cooperation of receiving equipment on satellites to receive and detect reflected light, resulting in high operating costs. In addition, due to the long distance between the satellite receiving equipment, it can only be assisted by natural light. Therefore, remote sensing measurements of large water bodies can only be carried out under clear skies. Summary of the Invention

[0006] The main purpose of the present invention is to provide a water quality remote sensing measurement device to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the present invention proposes a water quality remote sensing measurement device, comprising a suspended platform, a horizontal apron fixedly connected to the top of the suspended platform, a drone parked in the middle of the apron, four protective covers arranged near the edge of the top of the suspended platform, an electric shaft fixedly connected between the protective cover and the suspended platform, a receiving plate fixedly connected to the outer surface of one of the protective covers, two groups of symmetrically arranged propulsion fans arranged on the outside of the suspended platform, a steering module for controlling the steering of the propulsion fans arranged at one end of the propulsion fan close to the suspended platform, the steering module is connected to the outside of the suspended platform, a receiving plate is also fixedly connected to the outside of the drone, and a light transmitting device is fixedly connected to the outside of the drone. The module is placed on the water surface to suspend it through the setting of a suspended platform. When remote sensing measurement of water quality is required, the four protective covers on the suspended platform are opened to raise the drone equipment. The preset program allows the drone to fly to a high altitude and use the receiving board on the outside of the drone to receive data such as atmospheric scattering, water surface scattering, underwater scattering and bottom reflection of natural light. The received data is transmitted outward and spectrally analyzed to obtain water quality data. The drone can transmit measurement light to the water surface through the light transmitting module worn by the drone, and receive the measurement light through the receiving board on the outside of the suspended platform. Through this setting, the equipment can perform measurements in various environments.

[0008] Preferably, a hollow buoyancy chamber is provided inside the suspension platform, and the suspension platform is arranged in a pancake shape as a whole. The four protective covers include two semi-disc-shaped protective covers and two square protective covers. The two square protective covers are one long and one short. The outer side of the longer square protective cover is connected to the receiving plate. The receiving plate is arranged in sections, and the two sections of the receiving plates are rotatably connected by a hinge, and a power module is connected between the two sections of the receiving plates. The power module is used to allow one of the receiving plates to rotate with the hinge as the rotation axis. The top surface of the suspension platform is covered by the rotation of the four protective covers, so that the entire device becomes a large pancake shape. This device has a huge contact area with the water surface and will not easily tip over, allowing the device to stay on the water surface for a long time. When it needs to be used, the protective cover is opened to allow the drone to take off, and a longer protective cover is set so that this longer protective cover can completely cover the top of the drone. Even if a water leak occurs, the accumulated water will not drip directly onto the drone. At the same time, there is a larger area to install the receiving plate. The reversible setting of the receiving plate allows the two sections of the receiving plate to rotate and merge when not in use, reducing the impact of the outside world on it.

[0009] Preferably, the top of the helipad is fixed with a docking seat, which is arranged in a truncated cone shape. A docking sleeve that is transparent from top to bottom is fixed to the middle of the UAV, and the docking sleeve is used to be connected with the docking seat. A plurality of signal transmitters are fixed on the four sides of the top surface of the helipad, and a receiver corresponding to the signal transmitter is fixed inside the UAV. The UAV can find the location of the helipad by transmitting signals to each other through the signal transmitter and the receiver. When the UAV moves above the helipad, as the UAV descends, the docking sleeve in the middle of the UAV will be aligned with the truncated cone-shaped docking seat. The docking seat is narrow at the top and wide at the bottom. As the UAV descends, the docking seat and the docking sleeve are connected with each other. After the UAV stops completely, the docking seat can be inserted into the docking sleeve to ensure that the UAV is stably placed on the suspension platform. When the suspension platform as a whole is swayed by the wind, the UAV inside will not be affected.

[0010] Preferably, a negative pressure pipe is fixed to the bottom of the docking seat, and the bottom of the negative pressure pipe passes through the bottom of the suspended platform. The bottom of the negative pressure pipe is closed and communicates with the docking seat. An expansion pad of elastic material is fixed to the outside of the docking seat. The expansion pad is conical after expansion. A drainage pump and a water suction pump are fixed to the bottom of the negative pressure pipe. The output end of the water suction pump is fixed to an extension pipe extending outward.

[0011] Preferably, a metal top is fixed to the top of the conical expansion pad, and a plurality of fixing components are fixed to the outside of the docking seat, and the fixing components are used to fix the drone, wherein an anemometer is fixed to the outside of one of the semi-disc-shaped protective covers. The setting of the metal top makes the top of the expansion pad rigid, and helps the top of the expansion pad to be pushed out smoothly when it expands. The setting of the anemometer can measure the external airflow at all times, allowing the drone to take off and land when the external wind speed is low.

[0012] Preferably, the fixing assembly includes multiple locking rods, the edge of the expansion pad is fixed to the outer side of the docking seat near the top, and multiple slide grooves are opened on the outer side of the docking seat near the top, and the multiple slide grooves are arranged in a ring. One of the two holes of the slide groove is located on the inner side of the expansion pad, and the other is located on the outer side of the expansion pad. The locking rod is an elastic metal material, and the locking rod slides through the slide groove and its two ends extend out of the hole bodies at both ends of the slide groove. Multiple elastic sheets are fixed between the locking rod and the slide groove. Through this arrangement, the drone can be stably placed on the floating platform, and the drone will not slide and collide around due to the rollover of the floating platform. When the drone needs to fly out, the expansion pad needs to be expanded and pushed out first, so that the locking rod can be reset under the pull of the elastic sheet.

[0013] Preferably, a top ball is fixed to the top of the locking rod, a plurality of protrusions are fixed to the inner ring of the docking sleeve, and a fiber layer is attached to the outer top of the expansion pad. Through the arrangement of the top ball and the fiber layer, the force is dispersed when the expansion pad squeezes the locking rod, and it will not be too sharp to puncture the expansion pad.

[0014] Preferably, a concave water collection trough is provided on the outer edge of the floating platform, and a plurality of one-way valves are connected to the outside world. A waterproof board is fixedly connected between the bottom edge of the water collection trough and the apron, and the cross-section of the waterproof board is arc-shaped. When the protective cover is opened, the outside river water can easily enter the floating platform. The arc-shaped waterproof board can prevent the river water from entering the high apron. The river water accumulated in the water collection trough is discharged from the floating platform under the action of the one-way valve, thereby reducing the impact of the accumulated water on the electrical components.

[0015] Preferably, two symmetrically arranged air pumps are fixed to the outside of the suspension platform, and the output ends of the air pumps are vertically upward. The steering module is fixed to the outside of the air pumps. A detection component is provided at the bottom of the suspension platform. The detection component is used to detect the direction of the top surface of the suspension platform. Due to the strong wind and waves on the lake, the suspension platform is still in danger of overturning. When the drone is needed to work, the detection component is used to detect whether the top surface of the suspension platform is facing upward. When it is detected that the suspension platform is not facing upward, the air pump on one side is started to spray gas downward to make the suspension platform flip over, so that the suspension platform can return to the correct posture and the drone can take off and land normally.

[0016] Preferably, the detection component includes a water immersion sensor, and maintaining rods are fixed on both sides of the water immersion sensor. The maintaining rods are fixed on the inner wall of the negative pressure tube near the bottom. The water immersion sensor can detect whether it is in water. Since the water immersion sensor is suspended at the bottom of the negative pressure tube through the maintaining rod, when the bottom of the suspended platform is facing upward, the water immersion sensor will not be immersed in water. At this time, the air pump is used to return the suspended platform to its original position. When the front of the suspended platform is facing upward, the water immersion sensor sinks underwater, thereby knowing that the suspended platform is in a normal state and does not need to be reset.

[0017] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0018] (1) A water quality remote sensing measurement device of the present invention is placed on the water surface to suspend it by setting a suspension platform. When remote sensing measurement of water quality is required, the four protective covers on the suspension platform are opened to raise the drone equipment. The preset program allows the drone to fly to a high altitude and uses the receiving plate on the outside of the drone to receive data such as atmospheric scattering, water surface scattering, underwater scattering and bottom reflection of natural light. The water quality data is obtained by transmitting the received data outward and performing spectral analysis on it. Since the satellite receiving equipment is far away, it can only be assisted by natural light. Therefore, remote sensing measurement can only be performed under clear skies. The drone can transmit measurement light to the water surface through the light transmitting module it wears and receive the measurement light through the receiving plate on the outside of the suspension platform. Through this setting, the device can perform measurements in various environments.

[0019] (2) A water quality remote sensing measuring device of the present invention covers the top surface of the suspended platform by rotating four protective covers, so that the entire device becomes a large pancake shape. The contact area between the device and the water surface is huge and will not easily tip over, allowing the device to stay on the water surface for a long time. When needed, the protective cover is opened to allow the drone to take off. A longer protective cover is set so that the longer protective cover can completely cover the top of the drone. Even if a water leak occurs, the accumulated water will not drip directly onto the drone. At the same time, there is a larger area to install the receiving plate. The reversible setting of the receiving plate allows the two sections of the receiving plate to be rotated and merged when not in use, reducing the impact of the outside world on it.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] Example 1:

[0032] like Figures 1 to 3 As shown, a water quality remote sensing measuring device according to an embodiment of the present invention includes a floating platform 1, a horizontal apron 8 is fixedly connected to the top of the floating platform 1, a drone 2 is parked in the middle of the apron 8, four protective covers 3 are provided on the top edge of the floating platform 1, an electric shaft is fixedly connected between the protective cover 3 and the floating platform 1, a receiving plate 6 is fixedly connected to the outer surface of one of the protective covers 3, two groups of symmetrically arranged propulsion fans 5 are provided on the outside of the floating platform 1, a steering module 14 for controlling the steering of the propulsion fans 5 is provided at one end of the propulsion fans 5 close to the floating platform 1, the steering module 14 is connected to the outside of the floating platform 1, a receiving plate 6 is also fixedly connected to the outside of the drone 2, and a light emitting module for emitting measurement light outward is fixedly connected to the outside of the drone 2. When working, the existing water quality remote sensing needs to cooperate with the receiving equipment on the satellite to realize the reception and detection of reflected light, resulting in too high operating cost and low feasibility. Through the setting of the floating platform 1, the floating platform 1 is placed on the water surface so that Suspension. When remote sensing measurement of water quality is required, the four protective covers 3 on the suspension platform 1 are opened to allow the drone 2 equipment to rise. The preset program allows the drone 2 to fly to a high altitude and use the receiving plate 6 on the outside of the drone 2 to receive data such as atmospheric scattering, water surface scattering, underwater scattering and bottom reflection of natural light. By transmitting the received data outward and performing spectral analysis on it, water quality data can be obtained. Since the satellite receiving equipment is far away, it can only be assisted by natural light. Therefore, remote sensing measurement can only be performed under clear skies. The drone 2 can transmit measurement light to the water surface through the worn light transmission module, and the measurement light is received by the receiving plate 6 on the outside of the suspension platform 1. Through this setting, the equipment can perform measurements in various environments. The propulsion fans 5 on both sides rotate in the same direction at the same time, which can drive the suspension platform 1 to translate. The steering module 14 changes direction. The propulsion fan 5 has a wide diameter. Whether the suspension platform 1 is facing forward or overturned, the propulsion fan 5 can contact the water surface to ensure the mobile function.

[0033] like Figures 1 to 3 As shown, a hollow buoyancy chamber 11 is provided inside the suspension platform 1. The suspension platform 1 is in a circular pancake shape. The four protective covers 3 include two semi-disc protective covers 3 and two square protective covers 3. The two square protective covers 3 are one long and one short. The outer side of the longer square protective cover 3 is connected to the receiving plate 6. The receiving plate 6 is segmented. The two sections of the receiving plates 6 are connected by a hinge. A power module is connected between the two sections of the receiving plates 6. The power module is used to rotate one of the receiving plates 6 with the hinge as the rotation axis. When working, when the drone 2 completes its work and lands on the apron 8, it is rotated by the four protective covers 3. The rotation covers the top surface of the suspended platform 1, making the entire device into a large pancake shape. The contact area between this device and the water surface is huge and it will not easily tip over, allowing the device to stay on the water surface for a long time. When it is needed, the protective cover 3 is opened to let the drone 2 take off. A longer protective cover 3 is set so that this longer protective cover 3 can completely cover the top of the drone 2. Even if a water leak occurs, the accumulated water will not drip directly onto the drone 2. At the same time, there is a larger area to install the receiving plate 6. The reversible setting of the receiving plate 6 allows the two sections of the receiving plate 6 to be rotated and merged when not in use, reducing the impact of the outside world on it.

[0034] like Figures 3 and 4 and Figure 7 As shown, a docking socket 10 is fixed to the top of the helipad 8. The docking socket 10 is truncated and has a truncated cone shape. A docking sleeve 24, which is transparent from top to bottom, is fixed to the middle of the drone 2. Multiple signal transmitters 7 are fixed to the top surface of the helipad 8 along the four sides. A receiver corresponding to the signal transmitters 7 is fixed inside the drone 2. During operation, the difficulty in ensuring the stable operation of this equipment lies in the take-off and landing process of the drone 2. Since the take-off and landing of the drone 2 can only rely on the control of the preset system, the mutual transmission of signals between the signal transmitter 7 and the receiver allows the drone 2 to find the position of the helipad 8. When the drone 2 moves above the helipad 8, as the drone 2 descends, the docking sleeve 24 in the middle of the drone 2 will align with the truncated cone-shaped docking socket 10. The docking socket 10 is narrow at the top and wide at the bottom. As the drone 2 descends, the docking socket 10 and the docking sleeve 24 interlock with each other. After the drone 2 comes to a complete stop, the docking socket 10 can be inserted into the docking sleeve 24, ensuring that the drone 2 is stably placed on the floating platform 1. When the floating platform 1 is swayed by the wind, the drone 2 inside will not be affected.

[0035] like Figures 3 and 4As shown, a negative pressure pipe 9 is fixed to the bottom of the docking seat 10, and the bottom of the negative pressure pipe 9 passes through the bottom of the suspended platform 1. The bottom of the negative pressure pipe 9 is closed, and the negative pressure pipe 9 is connected to the docking seat 10. An expansion pad 16 of elastic material is fixed to the outside of the docking seat 10. The expansion pad 16 is conical after expansion. A drainage pump 17 and a water suction pump 18 are fixed to the bottom of the negative pressure pipe 9. The output end of the water suction pump 18 is fixed with an extension pipe 20 extending outward. During operation, when the drone 2 falls, the water is absorbed from the bottom of the suspended platform 1 by the water suction pump 18 and filled into the negative pressure pipe 9. As the filling progresses, the expansion pad 16 will be expanded into its original shape, that is, a cone. The conical expansion pad 16 is narrow at the top and wide at the bottom, so that the falling drone 2 can be smoothly docked as long as the docking sleeve 24 at the bottom The top of the expansion pad 16, at this time the drone 2 only needs to fall normally, and it can be finally connected with the docking seat 10 under the guidance of the conical expansion pad 16, and the expansion pad 16 is filled with river water and will not bend easily, and can effectively guide the drone 2. After the guidance is completed, the internal river water is discharged through the drainage pump 17. As the river water is discharged, the inside of the negative pressure tube 9 is close to a vacuum. Since the expansion pad 16 is an elastic material, the expansion pad 16 will be pulled downward, allowing the expansion pad 16 to enter the negative pressure tube 9 as a whole. Through this setting, the expansion pad 16 will not leak above the drone 2 after the drone 2 stops, and the protective cover 3 can be set to be close to the top of the drone 2 after rotating closed, further fixing the drone 2 when not in use, and ensuring the stability of the drone 2 during each take-off and landing.

[0036] like Figures 3 to 5 As shown, the top of the conical expansion pad 16 is fixed with a metal top 15, and the outer side of the docking seat 10 is fixed with multiple fixing components, which are used to fix the drone 2. The outer side of one semi-disc-shaped protective cover 3 is fixed with an anemometer. When working, the setting of the metal top 15 makes the top of the expansion pad 16 rigid, which helps it to expand, and the top of the expansion pad 16 can be pushed out smoothly. The setting of the anemometer can measure the external airflow at all times, allowing the drone 2 to take off and land when the external wind speed is low.

[0037] like Figures 5 and 6As shown, the fixing assembly includes multiple locking rods 21, the edge of the expansion pad 16 is fixed to the outer side of the docking seat 10 near the top, and the outer side of the docking seat 10 is provided with multiple slide grooves near the top, and the multiple slide grooves are arranged in a ring. One of the two holes of the slide groove is located on the inner side of the expansion pad 16, and the other is located on the outer side of the expansion pad 16. The locking rod 21 is made of elastic metal material. The locking rod 21 slides through the slide groove and its two ends extend out of the hole bodies at both ends of the slide groove. Multiple elastic sheets 23 are fixed between the locking rod 21 and the slide groove. When working, when the drone 2 stops outside the docking seat 10, as the drainage pump 17 continues to drain water and the inside of the negative pressure pipe 9 is evacuated to a vacuum, the elastic sheet 23 is fixed between the locking rod 21 and the slide groove. The expansion pad 16 will continue to descend. Since the edge of the expansion pad 16 is fixed to the outside of the docking seat 10, the upper part of the locking rod 21 will be squeezed as the outer expansion pad 16 is pulled, thereby pushing the bottom of the locking rod 21 outward, and the inner wall of the docking sleeve 24 of the drone 2 can be pressed against, thereby firmly grasping the drone 2 and the docking sleeve 24. Through this arrangement, the drone 2 is ensured to be stably placed on the floating platform 1, and the drone 2 will not slide around and collide due to the rollover of the floating platform 1. When the drone 2 needs to fly out, the expansion pad 16 needs to be expanded and pushed out first, allowing the locking rod 21 to be reset under the pull of the elastic sheet 23.

[0038] like Figures 5 and 6 As shown, a top ball 22 is fixed to the top of the locking rod 21, a plurality of protrusions are fixed to the inner ring of the docking sleeve 24, and a fiber layer is attached to the outer top of the expansion pad 16. During operation, the setting of the top ball 22 and the fiber layer allows the expansion pad 16 to disperse the force when squeezing the locking rod 21, and will not be too sharp to puncture the expansion pad 16. By setting the inner ring of the docking sleeve 24 to be fixed with a plurality of protrusions, the bottom of the locking rod 21 can be fixed on the bottom formed by the plurality of protrusions when it is pushed outward to play a locking role.

[0039] like Figure 3 As shown, a concave water collection trough 12 is provided on the outer edge of the floating platform 1. The water collection trough 12 is connected to the outside world by multiple one-way valves. A waterproof board 13 is fixedly connected between the bottom edge of the water collection trough 12 and the helipad 8. The cross-section of the waterproof board 13 is arc-shaped. During operation, when the protective cover 3 is opened, the outside river water can easily enter the floating platform 1. The arc-shaped waterproof board 13 can prevent the river water from entering the high helipad 8. The river water accumulated in the water collection trough 12 is discharged from the floating platform 1 under the action of the one-way valve, thereby reducing the impact of the accumulated water on the electrical components.

[0040] like Figures 1 to 3As shown, two symmetrically arranged air pumps 4 are fixed to the outside of the suspension platform 1, and the output end of the air pump 4 is vertically upward. The steering module 14 is fixed to the outside of the air pump 4. A detection component is provided at the bottom of the suspension platform 1. The detection component is used to detect the direction of the top surface of the suspension platform 1. During operation, due to the strong wind and waves on the lake, the suspension platform 1 is still in danger of overturning. When the drone 2 is needed to work, the detection component is used to detect whether the top surface of the suspension platform 1 is facing upward. When it is detected that the suspension platform 1 is not facing upward, the air pump 4 on one side is started to spray gas downward to make the suspension platform 1 flip over, so that the suspension platform 1 can return to the correct posture and the drone 2 can take off and land normally.

[0041] Example 2:

[0042] like Figure 4 As shown, in contrast to Example 1, another embodiment of the present invention is: the detection component includes a water immersion sensor 19, and a maintaining rod is fixed on both sides of the water immersion sensor 19, and the maintaining rod is fixed on the inner wall of the negative pressure tube 9 near the bottom. When working, the water immersion sensor 19 can detect whether it is in water. Since the water immersion sensor 19 is suspended at the bottom of the negative pressure tube 9 by the maintaining rod, when the bottom of the suspended platform 1 is facing upward, the water immersion sensor 19 will not be immersed in water. At this time, the air pump 4 is used to return the suspended platform 1 to its original position. When the front of the suspended platform 1 is facing upward, the water immersion sensor 19 sinks underwater, so that it is known that the suspended platform 1 is in a normal state and does not need to be reset.

[0043] When working, the existing water quality remote sensing needs to cooperate with the receiving equipment on the satellite to realize the reception and detection of reflected light, resulting in too high operating costs and low feasibility. Through the setting of the suspension platform 1, the suspension platform 1 is placed on the water surface to make it suspended. When remote sensing measurement of water quality is required, the four protective covers 3 on the suspension platform 1 are opened to let the drone 2 equipment rise. The preset program allows the drone 2 to fly to a high altitude, and the receiving plate 6 on the outside of the drone 2 is used to receive data such as atmospheric scattering, water surface scattering, underwater scattering and bottom reflection of natural light. By transmitting the received data outward and performing spectral analysis on it, water quality data can be obtained. The satellite receiving equipment is too far away. Because it is far away, it can only be assisted by natural light. Therefore, remote sensing measurement can only be carried out under clear skies. The drone 2 can transmit measurement light to the water surface through the light transmitting module worn by it, and receive the measurement light through the receiving plate 6 on the outside of the floating platform 1. Through this setting, the equipment can be measured in various environments. The propulsion fans 5 on both sides rotate in the same direction at the same time, which can drive the floating platform 1 to move horizontally. The steering module 14 changes direction. The propulsion fan 5 has a wide diameter. Regardless of whether the floating platform 1 is facing forward or overturned, the propulsion fan 5 can contact the water surface to ensure the mobile function. When the drone 2 completes its work and lands on the helipad 8, the four protective covers 3 are rotated to The top surface of the platform 1 is covered, making the entire device into a large pancake shape. The contact area between the device and the water surface is huge and will not easily tip over, allowing the device to stay on the water surface for a long time. When it is needed, the protective cover 3 is opened to allow the drone 2 to take off. A longer protective cover 3 is set so that the longer protective cover 3 can completely cover the top of the drone 2. Even if a water leak occurs, the accumulated water will not directly drip onto the drone 2. At the same time, there is a larger area to install the receiving plate 6. The reversible setting of the receiving plate 6 allows the two sections of the receiving plate 6 to rotate and merge when not in use, reducing the impact of the outside world on it. The difficulty in the stable operation of this device is the take-off and landing process of the drone 2. Since the take-off and landing of the drone 2 can only rely on the control of the preset system, the drone 2 can find the position of the helipad 8 through the mutual transmission of signals between the signal transmitter 7 and the receiver. When the drone 2 moves above the helipad 8, as the drone 2 descends, the docking sleeve 24 in the middle of the drone 2 will align with the frustum-shaped docking seat 10. The docking seat 10 is narrow at the top and wide at the bottom. As the drone 2 descends, the docking seat 10 and the docking sleeve 24 are interlocked. After the drone 2 comes to a complete stop, the docking seat 10 can be inserted into the docking sleeve 24, ensuring that the drone 2 is stably placed on the floating platform 1. When the floating platform 1 is swayed by the wind, the drone 2 inside will not be affected.When the drone 2 falls, the water is sucked from the bottom of the suspended platform 1 by the water suction pump 18 and filled into the negative pressure pipe 9. As the filling progresses, the expansion pad 16 will be expanded into its original shape, that is, a cone. The conical expansion pad 16 is narrow at the top and wide at the bottom, so that the falling drone 2 can smoothly dock with the top of the expansion pad 16 as long as the docking sleeve 24 at the bottom can fall. At this time, the drone 2 only needs to fall normally, and it can be guided by the conical expansion pad 16 to finally engage with the docking seat 10. The expansion pad 16 is filled with river water and will not bend easily, so it can effectively guide the drone 2. After the guidance is completed, the internal river water is discharged by the drainage pump 17. As the river water is discharged, the inside of the negative pressure pipe 9 is close to vacuum. Since the expansion pad 16 is made of elastic material, The expansion pad 16 will be pulled downward, allowing the expansion pad 16 to enter the negative pressure tube 9 as a whole. Through this arrangement, the expansion pad 16 will not leak out above the drone 2 after the drone 2 stops steadily, and the protective cover 3 can be set to be tightly attached to the top of the drone 2 after rotating and closing, further fixing the drone 2 in the unused state, and ensuring the stability of the drone 2 during each take-off and landing; the setting of the metal top 15 makes the top of the expansion pad 16 rigid, helping it to expand, and the top of the expansion pad 16 can be smoothly pushed out, and the setting of the anemometer can measure the external airflow at all times, allowing the drone 2 to take off and land when the external wind speed is low; when the drone 2 stops outside the docking seat 10, the inside of the negative pressure tube 9 is pumped to the vacuum state as the drainage pump 17 continues to drain water. After the drone 2 is empty, the elastic expansion pad 16 will continue to fall. Since the edge of the expansion pad 16 is fixed to the outside of the docking seat 10, the upper part of the locking rod 21 will be squeezed as the outer expansion pad 16 is pulled, thereby pushing the bottom of the locking rod 21 outward, and the inner wall of the docking sleeve 24 of the drone 2 can be pressed against, thereby firmly grasping the drone 2 and the docking sleeve 24. Through this arrangement, the drone 2 is guaranteed to be stably placed on the floating platform 1, and the drone 2 will not slide around and collide due to the rollover of the floating platform 1. When the drone 2 needs to fly out, the expansion pad 16 needs to be expanded and pushed out first, so that the locking rod 21 can be reset under the pull of the elastic sheet 23; through the arrangement of the top ball 22 and the fiber layer, the force of the expansion pad 16 squeezing the locking rod 21 is distributed. The protective cover 3 is open, allowing river water to easily enter the floating platform 1. The curved waterproof plate 13 prevents the water from entering the high-rise landing pad 8. The water is collected in the water trough 12 and drained out of the floating platform 1 by the one-way valve, reducing the impact of the water on the electrical components. Due to the strong waves on the lake, the floating platform 1 is still at risk of tipping over. When the drone 2 is required to operate, the detection component checks whether the floating platform 1 is facing up. If it detects that the floating platform 1 is not facing up, the air pump 4 on one side is activated to spray air downward, causing the floating platform 1 to flip over, allowing the floating platform 1 to return to its correct posture and allowing the drone 2 to take off and land normally.
