The lower end of the connecting rod is fixedly connected to the upper surface of the housing. Two impact protection mechanisms are arranged on the upper surface of the housing. The inside of the impact protection mechanism consists of a flow deflector, a flow splitter seat, and an arc-shaped groove. The two flow deflectors are fixedly connected to the left and right sides of the upper surface of the housing.

[0003] Although the above UAV flow measurement instrument can measure the water flow velocity when the UAV is flying, the disadvantages of the UAV flow measurement instrument are still: it is not convenient to install the UAV flow measurement instrument on the UAV body, resulting in troublesome connection steps with the UAV. Summary of the Utility Model

[0004] The utility model aims to provide a miniaturized device for measuring the flow velocity of an unmanned aerial vehicle, so as to solve the problem in the prior art that it is not convenient to install the UAV flow measurement instrument on the UAV body.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] The utility model discloses a miniaturized device for measuring the flow velocity of an unmanned aerial vehicle, including: a UAV body, a UAV connecting wire, and a radar flow velocity measurement box. A wiring interface is provided on the UAV body, and the wiring interface is connected to the first end of the UAV connecting wire. The second end of the UAV connecting wire is connected to the radar flow velocity measurement box. The radar flow velocity measurement box includes: a box body, a panel, a power supply and data interface board, a data processing board, a main control board, an antenna control board, a radar antenna, and a support connection mechanism. An installation space is formed inside the box body, and the installation space is fastened by the panel. The power supply and data interface board, the data processing board, the main control board, the antenna control board, and the radar antenna are arranged in sequence, and the power supply and data interface board is located on the side of the radar antenna away from the panel. Each component among the data processing board, the main control board, the antenna control board, the radar antenna, and the panel is a layered structure, and a gap is maintained between adjacent two-layered structures through the support connection mechanism. A groove is formed by the inward depression of the outer wall of the box body, and the groove is located beside the position where the power supply and data interface board is located. The groove of the box body is connected to the panel through a connecting screw. The second end of the UAV connecting wire is installed on the inner wall of the groove, and the power supply and data interface board is electrically connected to the battery inside the UAV body through the UAV connecting wire.

[0007] Preferably, the support connection mechanism includes: a screw with a connector and an end screw. The screw with a connector is provided between adjacent layered structures except between the radar antenna and the panel. A support ring is provided near the panel of the radar antenna, and the support ring is penetrated by the screw with a connector. The adjacent two screws with connectors between the radar antenna and the antenna control board are threadedly connected. Each intermediate layered structure is clamped by the screw with a connector. The data processing board is penetrated by the end screw, and the end screw is threadedly connected to the screw with a connector between the data processing board and the main control board.

[0008] Preferably, the support connection mechanism includes: a through screw and a plurality of nuts. The through screw sequentially penetrates the data processing board, the main control board, the antenna control board, and the radar antenna. The through screw is threadedly connected to the panel. A plurality of nuts are threadedly connected to the through screw. Threads are provided between adjacent layered structures. A nut is threadedly connected to the end of the through screw away from the panel, and the nut on the through screw away from the panel presses against the data processing board.

[0009] Preferably, a first bending section is formed by bending at the groove of the box body, and a second bending section is formed by bending the panel. The first bending section and the second bending section are buckled, and connection screws are connected at the first bending section and the second bending section.

[0010] Preferably, the power data interface board is installed on the data processing board, and the power data interface board is located beside the data interface of the data processing board. The data interface of the data processing board is communicatively connected to the controller in the drone body through the power data interface board.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1) By providing the drone connection line, the connection between the radar flow velocity measurement box and the drone body is realized, and at the same time, the battery power in the drone body is connected to the circuit in the radar flow velocity measurement box.

[0013] 2) In this application, a power data interface board, a data processing board, a main control board, an antenna control board, a radar antenna, and a support connection mechanism are stacked in sequence, resulting in a smaller occupied space, thereby reducing the volume of the entire radar flow velocity measurement box. After the above-mentioned power data interface board, data processing board, main control board, antenna control board, radar antenna, and support connection mechanism are stacked in sequence, although the power data interface board is small, it also increases the height of the box body. Therefore, to avoid further increasing the height of the box body, a groove is designed beside the power data interface board to install connecting screws at the groove to reduce the height of the box body. At the same time, the end of the UAV connecting wire is installed at the groove to further reduce the height of the box body. Meanwhile, the UAV connecting wire is set beside the power data interface board to shorten the wire between the UAV connecting wire and the power data interface board, which not only ensures the reduction of the height of the box body but also the wire between the UAV connecting wire and the power data interface board. The overall layout is optimized, making the radar flow velocity measurement box smaller in volume.

[0014] 3) By setting the support connection mechanism, not only the stacked installation between the panel, data processing board, main control board, antenna control board, and radar antenna is realized, but also the gap between each layered structure is maintained, avoiding mutual interference between the circuits on the data processing board, main control board, antenna control board, and radar antenna. Thus, both the stacked installation is achieved and the interference between circuits caused by stacking is avoided.

[0015] Other advantages, objectives, and features of the present utility model will be partially reflected by the following description and partially understood by those skilled in the art through the research and practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0021] Embodiment 1:

[0022] like Figure 1 as well as Figure 2 As shown, the utility model discloses a miniaturized UAV flow velocity measurement device, comprising: a UAV body 1, a UAV connection line 2 and a radar flow velocity measurement box 3, the UAV body 1 is provided with a wiring interface, the wiring interface is connected to the first end of the UAV connection line 2, and the second end of the UAV connection line 2 is connected to the radar flow velocity measurement box 3; the radar flow velocity measurement box 3 comprises: a box body 31, a panel 32, a power data interface board 33, a data processing board 34, a main control board 35, an antenna control board 36, a radar antenna 37 and a supporting connection mechanism 38, an installation space is formed in the box body 31, the installation space is buckled by the panel 32, the power data interface board 33, the data processing board 34, the main control board 35, the antenna control board 36, the radar antenna 37 and the supporting connection mechanism 38, 5. The antenna control board 36 and the radar antenna 37 are arranged in sequence, and the power data interface board 33 is located on the side of the radar antenna 37 away from the panel 32. Each component in the data processing board 34, the main control board 35, the antenna control board 36, the radar antenna 37 and the panel 32 is a layered structure, and a gap is maintained between two adjacent layered structures by a supporting connection mechanism 38. The outer wall of the box body 31 is recessed inward to form a groove, and the groove is located next to the position of the power data interface board 33; the groove of the box body 31 is connected to the panel 32 by a connecting screw 4, the second end of the drone connecting line 2 is installed on the inner wall of the groove, and the power data interface board 33 is electrically connected to the battery in the drone body 1 through the drone connecting line 2.

[0023] The supporting and connecting mechanism 38 includes: a screw with a connecting head 381 and an end screw 382. The screw with a connecting head 381 is arranged between adjacent layered structures except between the radar antenna 37 and the panel 32. A support ring 370 is arranged near the panel 32 of the radar antenna 37. The support ring 370 is penetrated by the screw with a connecting head. The two adjacent screws with a connecting head between the radar antenna 37 and the antenna control board 36 are threadedly connected. Each layered structure in the middle is clamped by the screw with a connecting head 381. The data processing board 34 is penetrated by the end screw 382. The end screw 382 is threadedly connected to the screw with a connecting head 381 between the data processing board 34 and the main control board 35. The height of the connector of the connector screw 381 is relatively large, and at the same time, the diameter of the connector of the connector screw 381 is relatively large and cannot pass through the layered structure. As a result, the connectors of two adjacent connector screws 381 can clamp the layered structure, thereby maintaining the gap between adjacent layered structures, avoiding mutual influence of circuits on the layered structure, and ensuring that the functions of the circuits on the layered structure can be realized normally.

[0024] A first bending section is formed by bending the groove of the box body 31, and a second bending section is formed by bending the panel 32. The first bending section and the second bending section are buckled, and a connecting screw 4 is connected at the first bending section and the second bending section. Installing the connecting screw 4 at the first bending section and the second bending section can prevent the connecting screw 4 from protruding from the end faces of the box body 31 and the panel 32.

[0025] The power data interface board 33 is installed on the data processing board 34, and the power data interface board 33 is located beside the data interface of the data processing board 34. The data interface of the data processing board 34 is communicatively connected to the controller in the drone body 1 through the power data interface board 33. The data processing board 34 processes the data obtained from the controller in the drone body 1 and then sends it to the main control board 35. The main control board 35 is communicatively connected to the data processing board 34. The controller in the drone body 1 collects image data through a camera or the like to obtain pictures of the flowing water, so as to expand the monitoring data range.

[0026] Embodiment 2:

[0027] The difference between this embodiment and Embodiment 1 is that the specific structure of the support connection mechanism 38 is different, and other components are the same as those in Embodiment 1.

[0028] As Figure 1 and Figure 3 shown, the support connection mechanism 38 includes: a through screw 383 and a plurality of nuts 384. The through screw 383 sequentially passes through the data processing board 34, the main control board 35, the antenna control board 36, and the radar antenna 37. The through screw 383 is threadedly connected to the panel 32, and a plurality of nuts 384 are threadedly connected to the through screw 383. Threads are provided between adjacent layered structures. A nut 384 is threadedly connected to the end of the through screw 383 away from the panel 32, and the nut 384 on the through screw 383 and away from the panel 32 is pressed against the data processing board 34. It realizes maintaining the distance between adjacent layered structures and the relative position between the layered structures through the nuts 384 located between adjacent two-layered structures. The nut 384 located at the end of the through screw 383 restricts the data processing board 34 on the outermost side from detaching from the through screw 383, so as to fully keep all the layered structures clamped by the two adjacent nuts 384.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
