A horizontal power device in the left-right direction is provided at the bottom of the first groove, and a height adjustment device is installed vertically upward on the horizontal power device.

[0004] The aforementioned charging pad can charge various types of drones. Meanwhile, the metal plate surface is equipped with solar panels, which can provide power to the power supply system when there is plenty of sunshine, and the metal plate can also serve as a rainproof measure on cloudy or rainy days.

[0005] However, when a drone lands directly on the conveyor belt, there may be a significant impact force. Without cushioning measures, this may affect the stability of the conveyor belt installation after prolonged use. Furthermore, it is difficult to secure the drone by adjusting the height of the charging port to charge it. When the plug is inserted, the drone is prone to shaking, affecting the accuracy of the connection. Summary of the Invention

[0006] The purpose of this invention is to provide a charging pad for environmental monitoring drones, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A charging pad for an environmental monitoring drone includes a charging pad assembly disposed below the drone body. The charging pad assembly has a charging box and two conveyor belts. The two conveyor belts are installed inside the charging box on both sides. The drone body is placed on the outer ring of the two conveyor belts via landing gear.

[0009] Circular dampers are fixedly installed on both sides of the charging box, near the front and rear ends. Circular dampers on the same side form a group. A buffer spring is installed at the top of each group of circular dampers. A mounting bracket is installed at the top of the buffer spring, and a transmission roller is rotatably installed on the inner side of the mounting bracket. A transmission belt spans the outer ring of the transmission rollers of the two mounting brackets. A drive motor is installed on one side of one of the mounting brackets.

A tensioning roller is installed at the end of the drive shaft of the electric telescopic rod, and the outer ring of the tensioning roller is in contact with the inner ring of the transmission belt.

[0010] Preferably, a support plate is fixedly installed on the side of the mounting bracket away from the drive motor, and a rubber buffer pad is installed on the top of the support plate, with the top surface of the rubber buffer pad being in contact with the bottom surface of the conveyor belt.

[0011] Preferably, the bottom end of the support plate is provided with an electromagnetic suction plate, which does not contact the tensioning roller.

[0012] Preferably, the top of the annular damper is provided with a mounting plate, and the top of the mounting plate is provided with a buffer rubber pad, the top surface of which is in contact with the bottom surface of the mounting frame.

[0013] Preferably, a protective plate is movably mounted at the top center of the charging box via a connecting plate, and an electric telescopic rod three is mounted at the bottom end of the connecting plate, with the end of the drive shaft of the electric telescopic rod three connected to the protective plate.

[0014] Preferably, a horizontal adjustment screw is rotatably mounted on the center of the interior of the drone body via a support block, and an electric telescopic rod II is installed on the outer thread of the horizontal adjustment screw.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, by setting up a charging pad assembly, can buffer the impact force when the drone lands on the conveyor belt through the combination of a circular damper, a buffer spring, and a buffer rubber pad, thereby reducing the impact force when the drone comes into contact with the conveyor belt. Furthermore, the rubber buffer pad support plate is installed below the conveyor belt, which can provide secondary support and buffering for the conveyor belt, ensuring that the conveyor belt will not deform downward due to the weight of the drone, thus improving the installation stability of the conveyor belt.

[0018] By using electromagnetic chucks and a conveyor belt in conjunction, once the drone is transported to the appropriate position, the electromagnetic chucks are energized to magnetically attract the drone, thus fixing its position and preventing it from shaking when the charging plug is inserted. This also prevents the drone from being blown around by the wind during the charging process, thereby improving charging stability. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Example 1

[0025] Combination Figures 1-3 A charging pad for an environmental monitoring drone includes a charging pad assembly 2 located below the drone body 1. The charging pad assembly 2 has a charging box and two conveyor belts 3. The two conveyor belts 3 are installed inside the charging box on both sides. The drone body 1 is placed on the outer ring of the two conveyor belts 3 via landing gear.

[0026] See Figure 2 and Figure 3Furthermore, it is found that circular dampers 5 are fixedly installed on both sides of the charging box, near the front and rear ends. Circular dampers 5 on the same side form a group. A buffer spring 6 is installed at the top of each group of circular dampers 5. A mounting bracket 4 is installed at the top of the buffer spring 6. A transmission roller is rotatably installed on the inner side of the mounting bracket 4. A transmission belt 3 spans the outer ring of the transmission rollers of two mounting brackets 4. A drive motor 8 is installed on one side of one of the mounting brackets 4. The drive shaft of the drive motor 8 is connected to the transmission roller of the mounting bracket 4. Circular dampers 5 are installed at the center positions on both sides of the charging box. There is an electric telescopic rod 9, and a tensioning roller 10 is installed at the end of the drive shaft of the electric telescopic rod 9. The outer ring of the tensioning roller 10 is in contact with the inner ring of the conveyor belt 3. A support plate is fixedly installed on the side of the mounting frame 4 away from the drive motor 8. A rubber buffer pad 11 is installed on the top of the support plate, and the top surface of the rubber buffer pad 11 is in contact with the bottom surface of the conveyor belt 3. A protective plate is movably installed at the top center of the charging box through a connecting plate. An electric telescopic rod 17 is installed at the bottom of the connecting plate, and the end of the drive shaft of the electric telescopic rod 17 is connected to the protective plate.

[0027] Specifically, when the drone body 1 lands on the conveyor belt 3, the conveyor belt 3 is movably mounted on the buffer spring 6 via the mounting bracket 4. The bottom end of the buffer spring 6 is equipped with a circular damper 5, and the buffer rubber pad 7 is attached to the mounting bracket 4 via the support top surface of the buffer plate. Thus, the impact force can be buffered in a timely and effective manner through the deformation of the circular damper 5, the buffer rubber pad 7, and the buffer spring 6. Furthermore, a support plate is installed below the conveyor belt 3, and a second rubber buffer pad 11 is installed at the top of the support plate. Simultaneously, the tension of the conveyor belt 3 can be adjusted by the up-and-down movement of the tension roller 10 driven by the electric telescopic rod 9. When the drone body 1 lands, the conveyor belt 3 can be kept in a slack state. At this time, the impact force generated by the landing of the drone body 1 will act on the rubber buffer pad 11 and the support plate to provide secondary buffer protection for the conveyor belt 3 itself, so as to avoid greater damage to the conveyor belt 3. After the drone body 1 comes to a stop, the drive motor 8 can be started. The drive shaft of the drive motor 8 rotates, which can drive the conveyor belt 3 to rotate, so as to drive the drone body 1 to move horizontally until the detection device on the drone body 1 detects that the charging interface and the charging plug 16 of the drone body 1 are at the same horizontal position, and then the transmission of the drive motor 8 stops.

[0028] Example 2

[0029] See Figure 2Furthermore, based on Embodiment 1, an electromagnetic suction plate 12 is provided at the bottom of the support plate. The electromagnetic suction plate 12 does not contact the tensioning roller 10. A mounting plate is provided at the top of the annular damper 5. A buffer rubber pad 7 is provided at the top of the mounting plate. The top surface of the buffer rubber pad 7 is in contact with the bottom surface of the mounting frame 4. A horizontal adjusting screw 13 is rotatably installed in the center of the inside of the UAV body 1 via a support block. An electric telescopic rod 15 is installed on the outer ring thread of the horizontal adjusting screw 13. A charging plug 16 that is compatible with the UAV body 1 is installed at the top of the electric telescopic rod 15 via a turntable. A power transmission cable is connected to one side of the charging plug 16. The electric telescopic rod 15 is slidably connected to the charging box. A drive motor 14 is installed on one side of the support block. The drive shaft of the drive motor 14 is connected to one end of the horizontal adjusting screw 13.

[0030] Specifically, when the drone body 1 moves to the charging position, the tension of the conveyor belt 3 can be released in the manner described above. At this time, the electromagnetic suction plate 12 can be energized to generate magnetic attraction to attract the landing gear of the drone body 1. This can prevent the drone body 1 from shaking during the insertion of the charging plug 16 and reduce the probability of the drone body 1 being blown by the wind, thereby improving charging stability. When the conveyor belt 3 is in a relaxed state, the support plate and the rubber buffer pad 11 support the drone body 1 to delay the probability of the conveyor belt 3 deforming, thereby reducing the frequency of maintenance and replacement.

[0031] In actual operation, the charging steps in the existing technology and the corresponding identification devices on the charging box will not be described in detail here. When the drone body 1 lands on the conveyor belt 3, the conveyor belt 3 is movably mounted on the buffer spring 6 through the mounting frame 4. At the same time, the bottom end of the buffer spring 6 is provided with a circular damper 5, and the buffer rubber pad 7 is attached to the mounting frame 4 through the support top surface of the buffer plate. Thus, the impact force can be buffered in a timely and effective manner through the deformation of the circular damper 5, the buffer rubber pad 7 and the buffer spring 6.

[0032] Furthermore, a support plate is installed below the conveyor belt 3, and a rubber buffer pad 11 is installed at the top of the support plate. The tension of the conveyor belt 3 can be adjusted by moving the tension roller 10 up and down through the electric telescopic rod 9. When the UAV body 1 lands, the conveyor belt 3 can be kept in a slack state. At this time, the impact force generated by the landing of the UAV body 1 will act on the rubber buffer pad 11 and the support plate. That is, the weight of the UAV body 1 and the impact force during landing will crush the conveyor belt 3. At this time, the rubber buffer pad 11 and the support plate will support the conveyor belt 3. At the moment of contact, the UAV body 1 is supported by the non-transfer belt 3 alone, so as to provide secondary buffer protection for the conveyor belt 3 itself, avoid major damage to the conveyor belt 3, and improve its service life.

[0033] After the drone body 1 comes to a stop, the push rod of the electric telescopic rod 9 can be retracted to drive the tensioning roller 10 to move downward, so that the conveyor belt 3 is in a tensioned state. At this time, the drive motor 8 can be started. The drive shaft of the drive motor 8 rotates, which can drive the conveyor belt 3 to rotate, so as to drive the drone body 1 to move horizontally until the detection device on the drone body 1 detects that the charging interface of the drone body 1 and the charging plug 16 are at the same horizontal position. Then, the transmission of the drive motor 8 is stopped, and the push rod of the electric telescopic rod 17 is retracted to drive the protective plate to retract, so that the upper part of the charging plug 16 is no longer blocked and protected.

[0034] When the drone body 1 moves to the charging position, the tension of the conveyor belt 3 can be released in the manner described above. At this time, the electromagnetic suction plate 12 can be energized to generate magnetic attraction force to attract the landing gear of the drone body 1. This can prevent the drone body 1 from shaking during the insertion of the charging plug 16 and reduce the probability of the drone body 1 being blown by the wind, thereby improving charging stability. When the conveyor belt 3 is in a relaxed state, the support plate and the rubber buffer pad 11 support the drone body 1 to delay the probability of the conveyor belt 3 deforming, thereby reducing the frequency of maintenance and replacement.

[0035] Furthermore, the display and control components and modules used in the aforementioned drive motor 18, electric telescopic rod 2 15, electric telescopic rod 1 9, electromagnetic chuck 12, and electric telescopic rod 3 17 are all existing technologies, which can be fully implemented by those skilled in the art and need not be elaborated upon. The power supply is also common knowledge in the field, and the content protected by this utility model does not involve any improvement to the software and methods.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
