Description

[Technical field]

[0001] The present invention relates to the field of drone technology, and more particularly to a drone anti-sloshing multi-layer array liquid storage device. [Background technology]

[0002] Because drones are lightweight and easy to control, the use of drones to load liquids onto vehicles and spray liquids at high altitudes has become increasingly common in recent years.

[0003] For example, a container filled with cleaning liquid is hung from a drone, the drone is controlled to rise and approach a high-voltage transmission tower, and the output pipe of the container is controlled to spray the cleaning liquid to clean the barrier of the transmission tower. This can greatly reduce the risk of falling or electric shock that may occur when climbing a transmission tower, and has the effect of saving time and labor.

[0004] In addition, for example, a container containing pesticide or fertilizer liquid can be hung from a drone, the drone can be controlled to fly over farmland, and the output pipe of the container can be controlled to spray the pesticide or fertilizer to the crops. This can greatly reduce the risk of poisoning caused by people coming into direct contact with the pesticide or fertilizer, and can have the effect of saving time and labor.

[0005] However, when a drone carrying liquid is used to perform work at height, the position of the center of gravity of the entire drone changes when the liquid in the container shakes, and the inertial force generated by the shaking of the liquid affects the stability of the drone's attitude control, making it impossible to reliably aim the cleaning liquid, pesticide or fertilizer liquid at the target.

[0006] The violent shaking of the liquid can be avoided by slowing down the drone's speed, but this will delay the operation time, or the volume of the liquid storage container can be reduced to reduce the space for the liquid to sway inside the container, but this method requires frequent refilling of the liquid and is not suitable for long-term or large-area operations. Summary of the Invention [Problem to be solved by the invention]

[0007] Based on this, the problem that those skilled in the art want to solve is how to develop a "drone sloshing prevention multi-layer array type liquid storage device" that can prevent the liquid inside the drone liquid storage device from sloshing and improve the stability of the drone during flight. [Means for solving the problem]

[0011] 1 to 3, the drone anti-sloshing multi-layer array liquid storage device 100 of the present invention includes a liquid storage unit 10 and a complex communicating pipe 20.

[0012] The liquid storage unit 10 includes one lower liquid storage unit 11 and multiple upper liquid storage units 12 .

[0013] The function of the lower liquid storage unit 11 and the upper liquid storage unit 12 is to hold liquid. According to actual needs, the liquid can be cleaning liquid, pesticide or fertilizer liquid.

[0014] The lower part of the lower liquid storage unit 11 has an output pipe 111, and the lower end of the output pipe 111 is an outlet end 112. The liquid in the lower liquid storage unit 11 can be ejected from the outlet end 112 of the output pipe 111, that is, the liquid is ejected downward.

[0015] However, depending on actual needs, the position of the output pipe 111 is not limited to the bottom of the lower liquid storage unit 11, and the outlet end 112 is not limited to being installed at the lower end of the output pipe, that is, the liquid spray direction is not limited to spraying downward.

[0016] 1 and 2, the horizontal height H12 of the upper liquid storage unit 12 is higher than the horizontal height H11 of the lower liquid storage unit 11.

[0017] A communication pipe 20 is provided between each upper liquid storage unit 12 and the lower liquid storage unit 11. The communication pipe 20 communicates with the internal space of each upper liquid storage unit 12 and the lower liquid storage unit 11.

[0018] In the embodiment of Fig. 1, each communicating pipe 20 has a check valve 21, so that the liquid in each upper liquid storage unit 12 flows into the lower liquid storage unit 11 in one direction through each communicating pipe 20, and can prevent the liquid in the lower liquid storage unit 11 from flowing back into the upper liquid storage unit 12 through the communicating pipe 20. However, the installation of the check valve 21 is not essential, and whether to install the check valve 21 can be determined according to the needs of the actual situation.

[0019] The materials and configurations of the communication pipe 20 and the check valve 21 are not limited, and may be, for example, acid-resistant and alkali-resistant materials.

[0020] After the liquid in each upper liquid storage unit 12 flows into the lower liquid storage unit 11 through each communication pipe 20, the liquid is sprayed out from the output pipe 111 and the outlet end 112 at the bottom of the lower liquid storage unit 11.

[0021] Regarding the method of controlling the flow of liquid from the high-level liquid storage unit 12 to the low-level liquid storage unit 11, the operator can control by remote control so that the liquid in each high-level liquid storage unit 12 is injected into the low-level liquid storage unit 11 at the same time in an equal amount based on the actual storage amount of liquid in the low-level liquid storage unit 11. In this way, the amount of liquid in each high-level liquid storage unit 12 is kept equal, and the liquid in the low-level liquid storage unit 11 can always be kept full, so that the low-level liquid storage unit 11 does not contribute to shaking. As for the liquid in each high-level liquid storage unit 12, although it is not in a cone state, the degree of shaking is greatly reduced because the liquid is distributed to different high-level liquid storage units 12.

[0022] In this embodiment, four high-rise liquid storage units 12 are provided, and the four high-rise liquid storage units 12 are arranged symmetrically at the same horizontal height H12 to form a rectangle. The lower-rise liquid storage unit 11 is located at the center of the four high-rise liquid storage units 12 and has a relatively low horizontal height H11. The center of gravity of the lower-rise liquid storage unit 11 is on the same central axis C as the centers of gravity of the four high-rise liquid storage units 12.

[0023] The spacing between adjacent high-rise liquid storage units 12 is not limited and is designed based on the actual size and shape of the drone and the high-rise liquid storage units 12.

[0024] 4 to 6, the coupling devices 30A, 30B are equipped with a lower liquid storage unit 11 and an upper liquid storage unit 12. The coupling devices 30A, 30B have a plurality of hooks 31A, 31B, and the coupling devices 30A, 30B are hung on a rack 202 of the unmanned vehicle 200 by the hooks 31A, 31B. This allows the lower liquid storage unit 11 and the upper liquid storage unit 12 to be installed on the unmanned vehicle 200.

[0025] Here, the drone 200 shown in Figures 4 and 6 is represented by a rack 202, and other structures of the complete drone such as the motor, propellers, batteries, etc. are not shown in order to clearly show how the lower liquid storage unit 11 and the upper liquid storage unit 12 are connected to the drone 200 by the coupling devices 30A, 30B.

[0026] When the lower liquid storage unit 11 and the upper liquid storage unit 12 are installed on the drone 200, the center of gravity of the lower liquid storage unit 11 and the center of gravity of the upper liquid storage unit 12 are located on the gravity axis C200 of the drone 200. Based on the understanding of people in the technical field of the present invention (i.e., the drone technical field), the gravity axis C200 of the drone 200 is, namely, the YAW axis of the drone 200.

[0027] It should be noted that the structure of the coupling devices 30A, 30B is based on the actual drone rack structure and is not limited to the aspects shown in Figures 4 and 5, as long as it can achieve the purpose that the lower liquid storage unit 11 and the upper storage unit 12 can be coupled to the drone rack. For example, the coupling devices 30A, 30B can be integrally formed and can be fixed with bolts to replace the hooks 31A, 31B.

[0028] Referring to the three-layer structure shown in Figures 7 and 8, which is derived based on the embodiment of Figures 2 and 3, it includes a lower liquid storage unit 11 and two upper liquid storage units 12, 12A located at different horizontal heights H12, H12A, respectively. The number of the upper liquid storage units 12, 12A increases from the uppermost upper liquid storage unit 12.

[0029] Each upper liquid storage unit 12 is connected to the lower liquid storage unit 11 by a communication pipe 20, and is further connected to two upper liquid storage units 12A symmetrically by two communication pipes 20A. Each of the communication pipes 20, 20A has a check valve 21, 21A.

[0030] Referring to the five-layer structure in Fig. 9 derived based on the embodiment in Fig. 7 and Fig. 8, it includes a lower liquid storage unit 11B and four higher liquid storage units 12B-12E located at different horizontal heights H12B-H12E, respectively. The number of higher liquid storage units 12B-12E increases from the bottom higher liquid storage unit 12B upwards.

[0031] Similarly, communicating pipes are provided between the lower liquid storage unit 11B and the upper liquid storage units 12B to 12E to connect them to each other, but these are omitted in Figure 9, and only the lower liquid storage unit 11B and the upper liquid storage units 12B to 12E arranged in an inverted pyramid are shown.

[0032] Furthermore, in the embodiment shown in Figure 9, the lower liquid storage unit 11B and the upper liquid storage units 12B-12E all have an elongated three-dimensional rectangular shape, which differs from the square and rectangular outer shapes of the lower liquid storage unit 11 and the upper liquid storage unit 12 shown in the embodiment in Figures 1-8.

[0033] FIG. 10 is derived based on the embodiment of FIG. 3, and includes one lower liquid storage unit 11C and four upper liquid storage units 12F. A communication pipe 20 is provided between the lower liquid storage unit 11C and the upper liquid storage unit 12F, and the communication pipe 20 has a check valve 21. The difference between the embodiment of FIG. 10 and FIG. 3 is that the size of the lower liquid storage unit 11C of FIG. 10 is smaller than the size of the upper liquid storage unit 12F.

[0034] Fig. 11 is derived based on the embodiment of Fig. 3, and includes one lower liquid storage unit 11 and three higher liquid storage units 12. A communication pipe 20 is provided between the lower liquid storage unit 11 and the higher liquid storage unit 12, and the communication pipe 20 has a check valve 21. The three higher liquid storage units 12 are symmetrically arranged at the same horizontal height to form a triangle.

[0035] FIG. 12 is derived based on the embodiment of FIG. 3, and includes one lower liquid storage unit 11D and five upper liquid storage units 12G. Between the lower liquid storage unit 11D and the upper liquid storage unit 12G, a communication pipe 20 is provided that is connected to each other, and the communication pipe 20 has a check valve 21. The five upper liquid storage units 12G are arranged at equal intervals at the same horizontal height to form a pentagon. Note that the lower liquid storage unit 11D and the upper liquid storage unit 12G of this embodiment are both circular in plan view, and their outer shapes may be spherical or cylindrical.

[0036] 1-12 show the structures of different embodiments, but they all have common technical features, including: The center of gravity of the lower liquid storage unit and the center of gravity of the higher liquid storage unit are located on the central axis of the drone. The structures of the lower liquid storage unit and the higher liquid storage unit may be the same or different, i.e., the liquid storage unit may have multiple sizes, structures or shapes. The higher liquid storage unit may be one layer or multiple layers. The number of the higher liquid storage units is greater than the lower liquid storage units. The lower liquid storage unit and the higher liquid storage unit are connected to each other via a communication pipe.

[0037] As shown in Figure 13, the drone anti-sloshing multi-layer array type liquid storage device 100H of the present invention includes a liquid storage unit 10H and a number of communicating pipes 20H. The lower part of the lower liquid storage unit 11H has an output pipe 111, and the lower end of the output pipe 111 is an outlet end 112.

[0038] The liquid storage unit 10H includes one lower liquid storage unit 11H and multiple upper liquid storage units 12H. A communication pipe 20H is provided between each of the upper liquid storage units 12H and the lower liquid storage unit 11H. In the embodiment of FIG. 13, the communication pipe 20H does not have a check valve 21 as shown in FIG. 2.

[0039] 14 and 15, the cross section of the lower liquid storage unit 11H is rectangular, and the lower liquid storage unit 11H has four rectangular upper spaces 112H and one pyramidal lower space 111H. The upper space 112H is located above the lower space 111H, and each of the upper spaces 112H and the lower space 111H is provided with four communication holes 113H that communicate with each other.

[0040] In the embodiments of Figures 14 and 15, the shape of each upper space 112H is the same and located at the same horizontal height, but in addition, upper spaces 112H with different shapes can be designed according to actual needs, and their horizontal heights may be different.

[0041] Referring to Figures 13 and 14, the structure of the upper liquid storage unit 12H and the external structure of the lower liquid storage unit 11H may be the same, or the interior of the upper liquid storage unit 12H may be a single space rather than being divided into different spaces like the lower liquid storage unit 11H.

[0042] When the inside of the upper liquid storage unit 12H is a single space, the liquid W of each upper liquid storage unit 12H first flows into each upper space 112H of the lower liquid storage unit 11H via each communication pipe 20H. At the same time, the liquid W of each upper space 112H flows into the lower space 111H via each communication hole 113H. Finally, the liquid W is sprayed from the outlet end 112 of the output pipe 111 at the bottom of the lower liquid storage unit 11.

[0043] 16 and 17, in Fig. 16, the cross section of the lower liquid storage unit 11J is hexagonal and is divided into six triangular upper spaces 112J, and each upper space 112J is provided with a communication hole 113J that communicates with the lower space (not shown). In Fig. 17, the cross section of the lower liquid storage unit 11K is hexagonal and is divided into three diamond-shaped upper spaces 112K, and each upper space 112K is provided with a communication hole 113K that communicates with the lower space (not shown).

[0044] 18 and 19, this embodiment is based on the embodiment of FIG. 13, the drone anti-sloshing multi-layer array liquid storage device 100M of the present invention includes one liquid storage unit 10M and multiple communication pipes 20M. The lower part of the lower liquid storage unit 11M has an output pipe 111, and the lower end of the output pipe 111 is an outlet end 112.

[0045] The lower liquid storage unit 11M has a plurality of upper spaces 112M and lower spaces 111M. The upper spaces 112M are located above the lower spaces 111M, and each of the upper spaces 112M and lower spaces 111M is provided with a plurality of communication holes 113M that communicate with each other.

[0046] The main difference between the embodiment of Fig. 18 and the embodiment of Fig. 13 is that each upper liquid storage unit 12M of the drone anti-sloshing multi-layer array liquid storage device 100M is provided with an exhaust valve 13, and each upper space 112M and lower space 111M of the lower liquid storage unit 11M is provided with an exhaust valve 13 that communicates with the outside atmosphere. The function of the exhaust valve 13 is as follows.

[0047] 18 and 19, the liquid W in each upper liquid storage unit 12M first flows into each upper space 112M of the lower liquid storage unit 11M via each communication pipe 20M. In the process in which the liquid W flows into each upper space 112M, the air A in the upper space 112M is discharged through the exhaust valve 13, and when the liquid level in the upper space 112M rises and contacts the exhaust valve 13, the exhaust valve 13 closes, completing the process of filling with the liquid W.

[0048] At the same time, the liquid W in each upper space 112M can flow into the lower space 111M via each communication hole 113M. Similarly, in the process in which the liquid W flows into the lower space 111M, the air A in the lower space 111M is discharged through the exhaust valve 13, and when the liquid level in the lower space 111M rises and comes into contact with the exhaust valve 13, the exhaust valve 13 closes, completing the process of filling with the liquid W.

[0049] Finally, the liquid W is ejected from the outlet end 112 of the output pipe 111 at the bottom of the lower liquid storage unit 11 .

[0050] 1, 7 to 12, 13, 16, and 17 to 19 show that the structure of the present invention is not limited to a specific form, and the structures of different embodiments can be mutually substituted.

[0051] For example, the check valve 21 in Fig. 1 is applicable to the embodiments in Figs. 7 to 12, 13, 16, and 17 to 19. The exhaust valve 13 in Fig. 18 is applicable to the embodiments in Figs. 1, 7 to 12, 13, 16, and 17. The two or more layer structure shown in Figs. 7 and 9 is applicable to the embodiments in Figs. 8, 10 to 13, and 16 to 19.

[0052] 20 and 21, the curves L1 and L3 represent a conventional single tank type liquid storage device, and the liquid volume size is 400x350x286 mm (mm). The curves L2 and L4 represent the drone anti-sloshing multi-layer array type liquid storage device provided by the present invention, the embodiment of which is as shown in Fig. 1 to Fig. 5, the liquid volume size of the lower liquid storage unit and the upper liquid storage unit is 200x200x200 mm (mm), and the total liquid volume size is 700x700x400 mm (mm).

[0053] Through experimental verification, it has been found that in the process of increasing the liquid level inclination angle, the values ​​of the horizontal offset of the center of gravity, the vertical offset of the center of gravity, etc. of the unmanned aircraft anti-sloshing multi-layer array liquid storage device provided by the present invention are all lower than those of the conventional single-tank liquid storage device, that is, the present invention can carry more liquid.

[0054] In summary, the drone-based anti-sloshing multi-layer array liquid storage device provided by the present invention divides and arranges liquid in inverted pyramid-shaped liquid storage units arranged in multiple layers, limiting the space in which the liquid sways to each liquid storage unit, thereby reliably preventing the liquid from swaying inside the drone-based liquid storage device and improving the stability of the drone during flight.

[0055] Although the present invention has been disclosed above by way of embodiments, the present invention is not limited thereto, and a person skilled in the art may make some changes and modifications without departing from the spirit and scope of the present invention.
