[0002] In the application of UAVs in agricultural meteorology, including pest monitoring, UAV hyperspectral remote sensing, with its high spatial resolution and mobile and flexible characteristics, can effectively obtain the spectral information of crops in the critical growth period, facilitating the effective inversion of yield. By mounting a hyperspectral remote sensing sensor on a UAV, the reflectivity of ground objects in multiple continuous spectral bands can be collected, enabling large-scale and non-contact rapid sampling. Existing UAV carrying devices usually fix the hyperspectral remote sensing sensor to the bottom of the UAV through bolts, which is inconvenient for installation and disassembly. Therefore, a remote sensing hyperspectral UAV carrying device for pest control is proposed to solve the above problems. Content of the Utility Model

A cavity is opened at the lower part of the multi-stage telescopic door, and an elastic plugging member is arranged therein, so that the elastic plugging member maintains a tendency to pop out to the side constantly. The multi-stage telescopic door is attached to the front end face of the connecting frame, so that before the multi-stage telescopic door is fully extended, the front end face abuts against and blocks the elastic plugging member, and after the multi-stage telescopic door is fully extended, the elastic plugging member pops out and inserts into the slot.

[0005] Further, it further includes a remote sensing sensor, and the remote sensing sensor is adapted to the opening of the connecting frame, so that the remote sensing sensor can be adaptively plugged into the connecting frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0018] Please refer to Figure 1-2 , a remote sensing hyperspectral UAV carrying device in the present application, includes a fuselage 1, a connecting frame 2 is fixedly provided at the lower end of the fuselage 1, the connecting frame 2 is a box body with openings at the front end and the lower end, and a receiving part 22 extending towards each other is provided at the lower end thereof, so that the lower opening is a narrow opening. Please refer to Figure 4 , the remote sensing sensor 3 is adapted to the opening of the connecting frame 2, so that the remote sensing sensor 3 can be adaptively inserted into the connecting frame 2;

[0019] The device is configured such that the connecting frame 2 serves as the main body for carrying the remote sensing sensor 3. The front end of the connecting frame 2 is open and set as the insertion port for the remote sensing sensor 3, used to insert the remote sensing sensor 3 into the connecting frame 2. The rear end is closed to form an abutting portion 24 that blocks the sensor, and the lower end is provided with a receiving portion 22, making the overall connecting frame 2 form a guide rail. The lower end, being a narrow opening, allows the probe of the remote sensing sensor 3 to extend out of the connecting frame 2;

[0020] Please refer to Figure 5 , on the upper part of the front-end opening of the connecting frame 2, there is a convex portion. Inside the convex portion, there is a storage cavity 25 communicating with the outside. Inside the storage cavity 25, there is an elastic multi-stage retractable door 26. The multi-stage retractable door 26 is a prior art, made of baffles with gradually decreasing volumes sleeved on each other. The baffles are connected by elastic members, and the elastic members constantly prop up the baffles, causing the multi-stage retractable door 26 to maintain a tendency to pop out downward constantly;

[0021] A cavity is provided in the lower part of the multi-stage retractable door 26, and an elastic insertion member 261 is arranged therein. The elastic insertion member 261 is similar to the multi-stage retractable door 26. Inside it, it is propped up by an elastic member, causing it to maintain a tendency to pop out to the side constantly. Before the multi-stage retractable door 26 is fully extended, the front end face of the connecting frame 2 abuts against and blocks the elastic insertion member 261 from popping out, making it be received in the cavity. A cross bar 23 with a spacing from the end face is provided on the lower end face of the connecting frame 2. A slot is formed between the cross bar 23 and the lower end face. After the multi-stage retractable door 26 is fully moved downward and extended, the elastic insertion member 261 crosses the lower end face of the connecting frame 2, pops out of the cavity, and inserts into the slot. In this state, the multi-stage retractable door 26 cannot be retracted or extended up and down;

[0022] In this way, before assembling the remote sensing sensor 3, the user can hold the multi-stage retractable door 26, prop up and compress it to expose the opening at the front end of the connecting frame 2. The remote sensing sensor 3 can be inserted into the connecting frame 2. After the remote sensing sensor 3 is inserted, the user releases the hand, causing the multi-stage retractable door 26 to automatically pop out of the convex portion under the action of the elastic member. Moreover, the lower part of the multi-stage retractable door 26 crosses the connecting frame 2. The connecting frame 2 no longer blocks the elastic insertion member 261 from popping out. The elastic insertion member 261 inserts into the slot, and the multi-stage retractable door 26 cannot be retracted or extended up and down to hold the remote sensing sensor 3 firmly;

[0023] When the drone is flying, the remote sensing sensor 3 cannot be moved out from the lower end and can only be moved out of the connecting frame 2 through the opening at the front end. The multi-stage telescopic door 26 acts as a stopper and is locked when the elastic connector 261 is inserted into the slot. When the drone is flying, there is no stress acting on the multi-stage telescopic door 26 up and down, and there is no stress acting on the elastic connector 261 left and right. There is no use scenario where two stresses act at the same time. The elastic connector 261 can be pushed into the multi-stage telescopic door 26 and the multi-stage telescopic door 26 can be opened upward. Therefore, this design can meet normal loading work and is sufficient to stably hold the remote sensing sensor 3. The elastic connector 261 and the cross bar 23 are correspondingly provided with buckles (not shown in the figure), so that when the elastic connector 261 is inserted into the slot, it forms an interference fit with the slot through deformation. When removing the elastic connector 261, the user needs to apply a large external force to remove the elastic connector. When moving it in, the user also needs to push and insert it, which further increases the holding effect.

[0024] See also Figure 3 Furthermore, a bayonet 21 is provided on the side wall of the connecting frame 2, and a groove is provided on the side wall of the remote sensing sensor 3. A spring 31 extending out of the groove is provided obliquely in the groove, and a clamping block 311 corresponding to the bayonet 21 is provided on the spring 31, so that when the remote sensing sensor 3 is inserted into the connecting frame 2, the clamping block 311 clamps the bayonet 21.

[0025] In order to further increase the holding effect of the device, in addition to the unidirectional holding of the remote sensing sensor 3 by the connecting frame 2, the connecting frame 2 and the remote sensing sensor 3 can also be held mutually by the remote sensing sensor 3. A spring sheet 31 bent outward is provided on the remote sensing sensor 3. The spring sheet 31 is an elastic sheet-like member. This is the prior art and will not be repeated in this application. The spring sheet 31 is arranged in a groove and is provided with a clamping block 311. In this way, when the remote sensing sensor 3 is inserted, the spring sheet 31 is resisted by the inner wall of the connecting frame 2 and bent into the groove. The clamping block 311 is received in the groove so that the remote sensing sensor 3 can be normally inserted into the connecting frame 2. When the clamping block 311 reaches the clamping port 21, under the elastic potential energy of the spring sheet 31, the spring sheet 31 is restored, and the clamping block 311 is engaged with the clamping port 21, thereby completing the mutual holding of the connecting frame 2 and the remote sensing sensor 3. In this way, the device realizes multi-angle and multi-component mutual holding, and meets the fixing strength for normal operation of an unmanned vehicle.

[0026] Furthermore, the bayonet 21 is a through opening penetrating through the side wall.

[0027] In order to facilitate disassembly and to facilitate removal of the block 311 after it is inserted into the bayonet 21, the bayonet 21 is set as a through port, so that the block 311 can be supported outside the connecting frame 2, thereby bending the spring sheet 31, so that the remote sensing sensor 3 can be directly pulled out.

[0028] Furthermore, the elastic connector 261 and the cross bar 23 are provided with anti-slip grooves.

[0029] The device further increases the friction between the elastic plug-in member 261 and the cross bar 23 and the stress of mutual engagement by providing anti-slip patterns, thereby increasing the firmness of the device.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
