Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a surveying UAV with a detachable rain cover. Background Technology

[0002] Surveying drones are mainly composed of three core modules: high-precision data acquisition (achieving centimeter-level accuracy through RTK positioning technology, eliminating the need for image control in planar coordinate operations), multi-sensor fusion (supporting the combination of equipment such as full-frame cameras, LiDAR, and multispectral sensors to meet different surveying needs), and intelligent flight path planning (allowing the setting of heading / lateral overlap rates (60%-80% recommended), supporting modes such as shock acquisition and intelligent oscillating shooting). They are currently used in fields such as urban planning, agricultural monitoring, and disaster relief.

[0003] Currently, when surveying drones are used outdoors in rainy weather, if rainwater enters the drone's interior, it can cause short circuits in precision components such as the ESC motherboard and flight control system. Therefore, it is necessary to install a rain cover to protect the drone from water. However, the main water-prone parts of the existing drones are located on both sides of the main body, i.e., the heat dissipation vents. But current rain covers are usually fully enclosed, which can affect the heat dissipation effect of the drone during normal use.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a mapping drone with a detachable rain cover, which solves the problem that the current rain covers are usually fully enclosed, which easily affects the heat dissipation effect of the drone body during normal use.

[0006] The technical solution adopted by this application to solve its technical problem is: a mapping drone with a detachable rain cover, including a drone body and heat dissipation vents on both sides of the outer wall of the drone body. The drone body has a flight frame fixedly installed on each of its four feet on the outer surface, and a propeller assembly is provided on one side of the upper end of the flight frame. The drone body has a rain cover installed on its outer surface with threaded limit.

[0007] The rainproof component includes a first mounting component and a second mounting component that is threadedly fixed to the lower end of the first mounting component. The first mounting component and the second mounting component are fixed together by a first T-shaped screw.

[0010] Furthermore, an insertion groove is provided at the lower center of the first upper closed recess, and a first extension block is fixedly installed at the lower end of one side of the outer wall of the first upper closed recess. Multiple circular grooves are provided at the upper end of the first extension block in a linear and equidistant manner.

[0011] Furthermore, the second mounting component includes a lower fixing frame and a corresponding groove formed in the middle of the bottom surface of the lower fixing frame, and second lower closing recesses are fixedly installed on both sides of the outer wall of the lower fixing frame.

[0012] Furthermore, an insertion block is fixedly installed at the upper end of the second lower sealing recess, and multiple ventilation holes are linearly and equally spaced on the bottom surface of the inner cavity of the second lower sealing recess. Second extension blocks are fixedly installed on the upper ends of both sides of the outer wall of the second lower sealing recess, and multiple hollow threaded rods are linearly and equally spaced on the upper end of the second extension blocks.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 As shown, the device includes a drone body 1 and heat dissipation vents 2 on both sides of the outer wall of the drone body 1. The heat dissipation vents 2 are designed to dissipate the heat generated by the internal components of the drone. Meanwhile, flight frames 3 are fixedly installed on the four feet of the outer surface of the drone body 1, and a propeller assembly 4 is provided on one side of the upper end of the flight frame 3. A rainproof component 5 is threadedly installed on the outer surface of the drone body 1. The rainproof component 5 is designed to protect the heat dissipation vents 2 and prevent rainwater from entering the inner cavity of the heat dissipation vents 2.

[0025] like Figure 2 As shown, the rainproof component 5 includes a first mounting component 51 and a second mounting component 52 that is threadedly fixed to the lower end of the first mounting component 51. The first mounting component 51 and the second mounting component 52 are fixed together by a first T-shaped screw 53.

[0026] Hollow threaded columns 11 are fixedly installed at the middle of the upper and lower ends of the outer wall of the drone body 1. At the same time, a second T-shaped screw 12 is threadedly connected to the inner cavity of the hollow threaded column 11. Both the first T-shaped screw 53 and the second T-shaped screw 12 are made of plastic.

[0027] like Figure 3 As shown, the first mounting assembly 51 includes an upper fixing frame 511 and a through groove 512 formed in the middle of the upper part of the top surface of the upper fixing frame 511. A hollow threaded column 11 is installed in the inner cavity of the through groove 512 and is threaded into the inner cavity of the hollow threaded column 11 by a second T-shaped screw 12 to fix the upper end of the upper fixing frame 511. A first upper closing recess 513 is fixedly installed on both sides of the outer wall of the upper fixing frame 511. An insertion groove 514 is formed in the middle of the lower end of the first upper closing recess 513. A first extension block 515 is fixedly installed on the lower end of one side of the outer wall of the first upper closing recess 513. A plurality of circular grooves 516 are formed linearly and equally spaced on the upper end of the first extension block 515.

[0028] The second mounting component 52 includes a lower fixing frame 521 and a corresponding groove 522 formed in the middle of the bottom surface of the lower fixing frame 521. Second lower closing recesses 523 are fixedly installed on both sides of the outer wall of the lower fixing frame 521.

[0029] like Figure 4 As shown, second extension blocks 526 are fixedly installed on the upper ends of both sides of the outer wall of the second lower closed recess 523. Multiple hollow threaded rods 527 are fixedly installed linearly and at equal intervals on the upper end of the second extension blocks 526. After the first upper closed recess 513 and the second lower closed recess 523 are tightly installed, the first extension block 515 and the second extension block 526 will fit together accordingly, so that the hollow threaded rods 527 are inserted into the inner cavity of the circular groove 516. By connecting the first T-shaped screw 53 to the inner cavity of the hollow threaded rod 527, the installation and fixation of the first extension block 515 and the second extension block 526 are achieved.

[0030] The first mounting component 51 and the second mounting component 52 are made of carbon fiber composite material to reduce the weight of the drone during flight.

[0031] In this application, when using the drone in rainy weather, the upper fixing frame 511 is first placed on the upper end of the drone, so that the hollow threaded post 11 is inserted into the inner cavity of the through groove 512, and the second T-shaped screw 12 is threaded into the inner cavity of the hollow threaded post 11 to achieve pre-fixation of the upper fixing frame 511. Similarly, the lower fixing frame 521 is installed on the lower end of the drone, so that the hollow threaded post 11 fixedly installed on the lower end of the drone is inserted into the inner cavity of the corresponding groove 522, and the lower fixing frame 521 is fixedly installed by the second T-shaped screw 12. At the same time as the lower fixing frame 521 is placed on the lower end of the drone, the insertion blocks 525 fixedly installed on both sides of the outer wall of the lower fixing frame 521 by the second lower closing recess 523 will... Inserted into the inner cavity of the insertion slot 514, the first extension block 515 and the second extension block 526 are mated and fitted together, so that the hollow threaded rod 527 fixedly installed on the upper end of the second extension block 526 is inserted into the inner cavity of the circular groove 516. The first T-shaped screw 53 is threaded into the inner cavity of the hollow threaded rod 527, thereby realizing the installation and fixation of the first extension block 515 and the second extension block 526. The first upper closing recess 513 and the second lower closing recess 523 are set on both sides of the heat dissipation port 2 to block the heat dissipation port 2 in rainy weather, thereby achieving a rainproof effect. At the same time, when the rainproof function is not used, the entire rainproof device can be disassembled by removing the second T-shaped screw 12 and the first T-shaped screw 53 respectively.

[0032] like Figure 3 As shown, an insertion block 525 is fixedly installed on the upper end of the second lower sealing recess 523. When the first upper sealing recess 513 and the second lower sealing recess 523 are connected, the insertion block 525 will be inserted into the inner cavity of the insertion groove 514, thereby achieving a tight installation of the first upper sealing recess 513 and the second lower sealing recess 523. The bottom surface of the inner cavity of the second lower sealing recess 523 is provided with multiple ventilation holes 524 at equal intervals. The ventilation holes 524 are designed to promote air circulation in the inner cavities of the first upper sealing recess 513 and the second lower sealing recess 523, thereby assisting the heat dissipation port 2 in heat dissipation.

[0033] In this application, after the first upper sealing recess 513 and the second lower sealing recess 523 are installed, in order to maintain the heat dissipation function of the heat dissipation port 2, a plurality of vent holes 524 are linearly and equally spaced on the bottom surface of the inner cavity of the second lower sealing recess 523. The vent holes 524 are used to introduce outside air from the lower end of the second lower sealing recess 523 to achieve the heat dissipation effect of the heat dissipation port 2, while rainwater is not easily allowed to enter the inner cavity of the heat dissipation port 2.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
