Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a water-resistant anti-sinking device for unmanned aerial vehicles. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are aircraft that fly without a pilot, but rather through remote control, autonomous control, or a combination of both. The most common type of UAV is the drone.

[0003] When performing tasks, existing drones sometimes need to conduct sampling or filming in special scenarios (such as large areas of water). These tasks require drones to fly over water for extended periods. If a mistake or malfunction occurs, the drone will fall into the water, causing not only equipment damage but also making it difficult to recover the drone. Since drones carry batteries, they can also easily cause water pollution. Therefore, it is necessary to equip drones with anti-sinking structures.

[0004] Currently, existing anti-sinking structures for drones generally use fixed floats as anti-sinking modules. In order to provide sufficient buoyancy, the float must be large enough, which increases weight and volume, affecting the drone's endurance and maneuverability. To solve the problems of the above two anti-sinking methods, this application provides an anti-sinking device for unmanned aerial vehicles to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a water-falling anti-sinking device for unmanned aerial vehicles to solve the problem that the existing fixed floats have too large a proportion of volume and weight, which affects the operation of the drone.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A water-falling anti-sinking device for unmanned aerial vehicles includes an unmanned aerial vehicle body, a base at the lower end of the unmanned aerial vehicle body, a holding module at the lower end of the base, swing modules on the front and rear sides of the lower end of the holding module, a sliding module at the outer end of the swing module, and an anti-sinking module at the lower end of the sliding module.

Columns are provided on the front and rear sides of the upper end of the landing gear, and a reinforcement hole is provided laterally on the outer end of the pull block.

[0008] Optionally, the holding module includes a base plate, side plates, positioning holes, shooting holes, and threaded holes. Side plates are provided on the left and right sides of the upper end of the base plate. Positioning holes are provided laterally on the outer ends of the side plates. Shooting holes are provided in the middle of the upper end of the base plate. Threaded holes are provided on the front and rear sides of the shooting holes.

[0009] Optionally, the swing module includes a lifting ring block, a swing sleeve, a support rod, a positioning pin, a limiting ring, and a pin. The swing sleeve is provided below the lifting ring block, the support rod is provided in the middle of the outer end of the swing sleeve, the positioning pin is provided on the inner side of the upper end of the lifting ring block, the limiting ring is provided on the outer side of the lower end of the positioning pin, and the pin is provided in the middle of the outer end of the limiting ring.

[0010] Optionally, the sliding module includes an arc-shaped compartment, a storage cavity, an arc-shaped groove, and an arc-shaped slider. There are two arc-shaped compartments symmetrically distributed on the left and right sides. The storage cavity is opened in the middle of the inner side of the arc-shaped compartment. An arc-shaped groove is opened on the front side of the storage cavity. An arc-shaped slider is provided inside the arc-shaped groove.

[0011] Optionally, the anti-sinking module includes a left arc box, a right arc box, a floating block, an embedded block, and an embedded strip. The right arc box is provided on the right side of the left arc box. Floating blocks are provided on the front and rear sides inside the left and right arc boxes. An embedded block is provided at the upper end of the floating block. An embedded strip is provided on the front and rear sides at the upper end of the left and right arc boxes.

[0012] Optionally, the drone body and the base are reinforced with screws, the base and the clamping module are clamped together, and the sides of the contact ends of the two are reinforced with screws. The contact ends of the swing module and the clamping module are reinforced with threads, and the contact ends of the swing module and the sliding module are reinforced with screws. There are four sets of swing modules symmetrically distributed. The upper end of the anti-sinking module extends to the inner side of the lower end of the sliding module, and the contact ends of the two are glued together.

[0013] Optionally, the base plate and the side plate are integrated into one piece, the positioning holes are symmetrically distributed from left to right, and the threaded holes are symmetrically distributed in four sets, with two on each side.

[0014] Optionally, the outer side of the upper end of the lifting ring block is threaded, the contact end of the swing sleeve with the lifting ring block is circumferentially embedded with a ball, the support rod and the swing sleeve are integrally formed, the lower end of the positioning pin passes through the interior of the lifting ring block, the swing sleeve and the limiting ring from top to bottom, and extends to the lower outer side, the contact end of the limiting ring and the swing sleeve is circumferentially embedded with a ball, and the front end of the pin passes through the interior of the limiting ring and the positioning pin, and continues to extend to the outer side.

[0015] Optionally, there are four symmetrically distributed storage cavities, arc-shaped grooves, and arc-shaped sliders, with two on each side, and the rear end of the arc-shaped sliders extends into the interior of the storage cavity.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, a symmetrical arc-shaped structure is formed on the outside of the holding module by setting a sliding module. The sliding module is pulled and reinforced by the swing module. Before operation, the two sets of swing modules in the front and the two sets of swing modules in the back are moved towards the central axis, so that the arc-shaped sliders in the left and right sets of sliding modules slide out of the arc-shaped groove to complete the docking. This causes the floating blocks inside the lower left and right arc boxes to slide out synchronously, forming a ring-shaped hollow floating structure under the drone body. Compared with the traditional fixed-size float structure, the overall weight is lighter and the volume is reduced, thus reducing the impact on the drone.

[0017] With the anti-sinking module in place, since the left and right arc boxes are the same size and shape, when the floating blocks inside them slide out from the inside and dock, they will increase the anti-sinking contact area under the drone body. At the same time, the cavities of the left and right arc boxes can also improve the overall buoyancy and enhance the anti-sinking effect of the device. Attached Figure Description

[0027] like Figures 1 to 7 As shown, an embodiment of the present invention provides a water-falling anti-sinking device for an unmanned aerial vehicle, including an unmanned aerial vehicle body 1, a base 2 at the lower end of the unmanned aerial vehicle body 1, a clamping module 3 at the lower end of the base 2, swing modules 4 on the front and rear sides of the lower end of the clamping module 3, a sliding module 5 at the outer end of the swing module 4, and an anti-sinking module 6 at the lower end of the sliding module 5.

[0028] The drone body 1 is reinforced with screws to the base 2. The base 2 is installed with the clamping module 3 in a clamping manner, and the sides of the contact ends of the two are reinforced with screws. The contact ends of the swing module 4 and the clamping module 3 are reinforced with threads. The contact ends of the swing module 4 and the sliding module 5 are reinforced with screws. There are four sets of swing modules 4 symmetrically distributed. The upper end of the anti-sinking module 6 extends to the inner side of the lower end of the sliding module 5, and the contact ends of the two are glued together.

[0029] By setting up sliding modules 5, a symmetrical arc structure is formed on the outside of the holding module 3. The sliding modules 5 are pulled and reinforced by swing modules 4. Before operation, the two sets of swing modules 4 in the front and the two sets of swing modules 4 in the back are moved towards the central axis, so that the arc sliders 504 in the left and right sliding modules 5 slide out from the arc grooves 503 to complete the docking. This causes the floating blocks 603 inside the lower left arc box 601 and right arc box 602 to slide out synchronously, forming a ring-shaped hollow floating structure under the UAV body 1. Compared with the traditional fixed-size float structure, the overall weight is lighter and the volume is reduced, thus reducing the impact on the UAV.

[0030] like Figures 1 to 4As shown, the base 2 includes a landing gear 201, a pull block 202, a slot 203, a column 204, and a reinforcement hole 205. The lower end of the landing gear 201 is provided with a pull block 202. A slot 203 is provided on the outer side of the pull block 202 that contacts the landing gear 201. Columns 204 are provided on the front and rear sides of the upper end of the landing gear 201. A reinforcement hole 205 is provided laterally on the outer end of the pull block 202. The clamping module 3 includes a base plate 301, a side clamping plate 302, a positioning hole 303, a shooting hole 304, and a threaded hole 305. Side clamping plates 302 are provided on the left and right sides of the upper end of the base plate 301. A positioning hole 303 is provided laterally on the outer end of the side clamping plate 302. A shooting hole 304 is provided in the middle of the upper end of the base plate 301. Threaded holes 305 are provided on the front and rear sides of the shooting hole 304.

[0031] The landing gear 201 and the pull block 202 are integrated structures, both of which are symmetrically distributed from left to right. There are two symmetrical slots 203 on the left and right. There are four symmetrically distributed columns 204, two on each side, located on the front and rear sides of the upper end of one landing gear 201. There are two rows of symmetrically distributed reinforcing holes 205, both rows of reinforcing holes 205 penetrating the interior of the two pull blocks 202. The distribution spacing of the reinforcing holes 205 is equal to the distribution spacing of the positioning holes 303. The base plate 301 and the side plate 302 are integrated structures. The positioning holes 303 are symmetrically distributed from left to right. There are four sets of symmetrically distributed threaded holes 305, two on each side.

[0032] The base 2 serves as the frame support structure for the UAV body 1. Meanwhile, the pull block 202 at the lower end of the landing gear 201, together with the slot 203 on the outer side of the contact end of the two, forms a sliding clamping structure with the side clamping plate 302 in the clamping module 3, which facilitates subsequent disassembly. Furthermore, the reinforcement hole 205, together with the positioning hole 303, can limit the sliding clamping structure and improve the stability after assembly.

[0033] like Figure 3 and Figure 5 As shown, the swing module 4 includes a lifting ring block 401, a swing sleeve 402, a support rod 403, a positioning pin 404, a limiting ring 405, and a pin 406. The swing sleeve 402 is located below the lifting ring block 401. The support rod 403 is located in the middle of the outer end of the swing sleeve 402. The positioning pin 404 is located on the inner side of the upper end of the lifting ring block 401. The limiting ring 405 is located on the outer side of the lower end of the positioning pin 404. The pin 406 is located in the middle of the outer end of the limiting ring 405.

[0034] The upper outer side of the lifting ring block 401 is threaded. A ball bearing is annularly embedded at the contact end between the swing sleeve 402 and the lifting ring block 401. The support rod 403 and the swing sleeve 402 are integrally formed. The lower end of the positioning pin 404 passes through the interior of the lifting ring block 401, the swing sleeve 402, and the limiting ring 405 sequentially from top to bottom, extending to the lower outer side. A ball bearing is annularly embedded at the contact end between the limiting ring 405 and the swing sleeve 402. The front end of the pin 406 passes through the interior of the limiting ring 405 and the positioning pin 404, continuing to extend to the outer side. The swing module 4 is designed with four sets symmetrically distributed front and rear, and two sets on each side. The contact ends of the swing sleeve 402 with the lifting ring block 401 and the limiting ring 405 are all embedded with annularly distributed ball bearings. These three components are connected by a positioning pin 404, forming a sleeve-mounted structure. Simultaneously, the outer end of the support rod 403 is connected and reinforced with four symmetrically distributed arc-shaped sliders 504. Before operation, simply moving the two front sets of swing modules 4 and the two rear sets of swing modules 4 towards the central axis allows the left and right sets of sliding modules 504 to move. The arc-shaped slider 504 slides out from the arc-shaped groove 503 to complete the docking, which drives the floating blocks 603 inside the lower left arc box 601 and right arc box 602 to slide out synchronously, forming a ring-shaped hollow floating structure under the drone body 1. When not working in the water surface area, the four sets of swing modules 4 can be manually operated to expand, which can move the arc-shaped slider 504 in the opposite direction along the arc-shaped groove 503 to the storage cavity 502, and simultaneously drive the floating blocks 603 to be stored in the cavities inside the left arc box 601 and right arc box 602, completing the storage of the anti-sinking structure.

[0035] like Figures 1 to 7 As shown, the sliding module 5 includes an arc-shaped compartment 501, a storage cavity 502, an arc-shaped groove 503, and an arc-shaped slider 504. There are two arc-shaped compartments 501 symmetrically distributed on the left and right sides. The storage cavity 502 is opened in the middle of the inner side of the arc-shaped compartment 501. The arc-shaped groove 503 is opened on the front side of the storage cavity 502. The arc-shaped slider 504 is provided inside the arc-shaped groove 503. The anti-sinking module 6 includes a left arc box 601, a right arc box 602, a floating block 603, an embedded block 604, and an embedded strip 605. The right arc box 602 is provided on the right side of the left arc box 601. The floating blocks 603 are provided on the front and rear sides inside the left arc box 601 and the right arc box 602. The embedded blocks 604 are provided at the upper end of the floating blocks 603. The embedded strips 605 are provided on the front and rear sides at the upper end of the left arc box 601 and the right arc box 602.

[0036] There are four symmetrically distributed storage cavities 502, arc-shaped grooves 503, and arc-shaped sliders 504, two on each side. The rear end of the arc-shaped sliders 504 extends into the interior of the storage cavity 502. A short slot is formed on the lower inner side of the front end of the arc-shaped sliders 504, while a long slot is formed on the lower rear end of the arc-shaped sliders 504. The inner diameter of the short slot matches the outer diameter of the embedded block 604, while the inner diameter of the long slot matches the outer diameter of the embedded strip 605. The left arc box 601 and the right arc box 602 are completely identical in size and shape. Both are identical, and both have floating blocks 603 embedded inside. There are four floating blocks 603 symmetrically distributed. The embedded block 604 and the floating block 603 are integrated. There are two embedded strips 605 symmetrically distributed at the upper end of the left arc box 601 and the right arc box 602. The embedded strips 605 are integrated with the left arc box 601 and the right arc box 602. The embedded block 604 extends upward to the lower inner side of the front end of the arc slider 504, while the embedded strip 605 extends upward to the lower inner side of the rear end of the arc slider 504.

[0037] By setting up sliding modules 5, a symmetrical arc structure is formed on the outside of the holding module 3. The sliding modules 5 are pulled and reinforced by swing modules 4. Before operation, the two sets of swing modules 4 in the front and the two sets of swing modules 4 in the back are moved towards the central axis, so that the arc sliders 504 in the left and right sliding modules 5 slide out from the arc grooves 503 to complete the docking. This causes the floating blocks 603 inside the lower left arc box 601 and right arc box 602 to slide out synchronously, forming a ring-shaped hollow floating structure under the UAV body 1. Compared with the traditional fixed-size float structure, the overall weight is lighter and the volume is reduced, thus reducing the impact on the UAV.

[0038] With the anti-sinking module 6 in place, since the left arc box 601 and the right arc box 602 are of equal size and shape, when the floating block 603 inside them slides out from the inside and completes docking, it will increase the anti-sinking contact area under the drone body 1. At the same time, the cavities of the left arc box 601 and the right arc box 602 can also improve the overall buoyancy and enhance the anti-sinking effect of the device.

[0039] The working principle of the technical solution provided by this utility model is as follows: Before operation, the two sets of front swing modules 4 and the two sets of rear swing modules 4 are moved towards the central axis, allowing the arc-shaped sliders 504 in the left and right sliding modules 5 to slide out from the arc-shaped sliding grooves 503 to complete the docking. This causes the floating blocks 603 inside the lower left arc box 601 and right arc box 602 to slide out synchronously, forming a ring-shaped hollow floating structure under the drone body 1. Compared with the traditional fixed-size float structure, the overall weight is lighter and the volume is reduced, reducing the impact on the drone. Furthermore, through the anti-sinking module 6, since the left arc box 601 and right arc box 602 are of equal size and shape, when the floating blocks 603 inside them slide out from the inside to complete the docking, the anti-sinking contact area under the drone body 1 will be increased. At the same time, the cavities of the left arc box 601 and right arc box 602 can also improve the overall buoyancy and enhance the anti-sinking effect of the device.

[0040] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
