Description

Technical Field

[0001] This invention relates to the field of UAV ground operation technology, specifically to an integrated ground operation system for UAV high-altitude cleaning. Background Technology

[0002] In recent years, with the increasing number of high-altitude operation scenarios such as glass curtain walls of high-rise buildings, large photovoltaic power station panels, insulators of ultra-high voltage transmission lines, and facades of large ships, traditional manual high-altitude cleaning methods have become difficult to meet market demands due to their low efficiency, high safety risks, and high costs. Drones equipped with cleaning devices are gradually becoming the mainstream cleaning solution in the aforementioned fields due to their significant advantages such as mobility, flexibility, no need for scaffolding, and remote control operation by personnel on the ground. Currently, ground support equipment suitable for drone-based high-altitude cleaning operations suffers from the following main technical deficiencies: First, for different types of dirt (such as oil and dirt on glass curtain walls, electrostatic dust on photovoltaic panels, and organic pollutants in exterior wall paint), different cleaning agents with different compositions or concentrations are often required. However, most existing ground liquid supply equipment is a single agent supply system, which cannot store multiple agents at the same time and switch flexibly according to the cleaning target. This results in poor adaptability of a single agent to different types of dirt, and the cleaning effect is difficult to guarantee. Secondly, when it is necessary to mix and prepare a specific concentration of medicine solution, traditional equipment relies on manual measurement and manual stirring, which is cumbersome to operate, has low ratio accuracy, and makes it difficult to ensure the consistency of the medicine solution concentration. Third, the existing refueling methods for drones mostly involve manually inserting and removing hoses to replenish the fluid. Operators need to manually connect the hoses, open the valves, wait for the refueling to be completed, and then manually remove the hoses after the drone lands. This process involves many steps and is time-consuming. To address the shortcomings of the existing technologies, this invention provides a ground-based integrated operation system for aerial cleaning by unmanned aerial vehicles (UAVs). The system aims to solve technical problems such as limited agent variety, low mixing accuracy, and poor dispensing efficiency in existing equipment through structural optimization and system integration innovation.

[0017] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0018] Example 1 Please see Figures 1 to 11 The present invention preferably provides the following technical solution: a ground integrated operation system for high-altitude cleaning by unmanned aerial vehicles (UAVs), comprising: a base 01; a water supply steel pipe vertically mounted on the base 01; several sets of annular water storage modules 03 connected to and communicating with the water supply steel pipe; and a rotating core water outlet column, comprising a drive rotor 031 mounted on the base 01, and a multi-channel rotating column mounted with the drive rotor 031, the multi-channel rotating column being located at the center of the several sets of annular water storage modules 03 and rotatably mounted therewith, and the multi-channel rotating column being rotatable with the several sets of annular water storage modules 03. 3. A series of outlet pipes 036 are connected to the base 01 and extend upwards and laterally; a multi-tank feeding module 04 is set on the base 01 and connected to a multi-piston drive assembly. The multi-piston drive assembly corresponds to and is connected to several sets of annular water storage modules 03, and is used to add a certain amount of agent to several sets of annular water storage modules 03; a drone feeding platform 05 is placed on top of the annular water storage module 03 and is connected to a pipe docking assembly. Under the action of the pipe docking assembly, the drone can dock and connect with the outlet pipe 036 at the corresponding position to achieve rapid replenishment.

[0019] This invention constructs a multi-layered, three-dimensional water storage structure by connecting several sets of annular water storage modules 03 to a vertical water supply steel pipe. Combined with a multi-tank supply module 04, it can store different types or concentrations of cleaning agents, thereby achieving selective distribution and orderly supply of different solutions or the same solution of different concentrations to water layers at different heights. Specifically, as shown... Figure 1 , 2As shown in Figures 3, 4, 6, and 7, the corresponding multi-piston drive assembly is connected to several sets of annular water storage modules 03 one-to-one. Through the independent stroke control of each piston, a quantitative amount of chemical agent can be added to different annular water storage modules 03 according to a set ratio, realizing differentiated chemical solution ratios for different water storage layers. This structure allows for the storage of different types of chemical solutions at the work site according to the type of dirt on the high-altitude cleaning target (such as glass curtain walls, photovoltaic panels, exterior wall coatings, etc.), expanding the scope of operations. On the other hand, it allows for flexible adjustment of cleaning solution according to the type of dirt on the high-altitude cleaning target, avoiding the problem of poor adaptability of a single chemical agent concentration to different types of dirt. Secondly, this invention features a multi-channel rotating column rotatably installed at the center of several sets of annular water storage modules 03. This multi-channel rotating column can rotate independently and can also be connected to several sets of annular water storage modules 03 respectively. Figure 3 As shown, when the drive rotor 031 drives the multi-channel rotating column to rotate, on the one hand, it accelerates the independent mixing of the liquid inside several sets of annular water storage modules 03; on the other hand, the structural design of the multi-channel rotating column extending upward and connecting to several liquid outlet pipes 036 laterally allows a single rotating column 032 to serve multiple liquid outlet stations at the same time, which not only facilitates the switching of liquid outlet stations, but also simplifies the pipeline layout and reduces system complexity and manufacturing costs.

[0020] Furthermore, the present invention includes a drone-based material feeding platform 05 on top of the annular water storage module 03, such as... Figure 1 , 9 10 and Figure 11 As shown, and equipped with a pipe docking assembly, after the drone lands on the feeding platform, the onboard liquid tank of the drone can be semi-automatically docked and connected with the corresponding liquid outlet pipe 036 through the pipe docking assembly to complete rapid material replenishment. This design eliminates the step of manually inserting and unplugging the pipes, reducing the drone material replenishment time from several minutes of traditional manual operation to tens of seconds, greatly increasing the drone's operation frequency and effective daily operation time. It is particularly suitable for high-altitude cleaning scenarios with high requirements for operation timeliness, such as the facade of high-rise buildings.

[0021] In summary, this invention constructs a ground-based integrated operation system that integrates clean water supply, chemical preparation, mixing, and rapid drone-based dispensing by using a three-dimensional stacked layout of water supply steel pipes and multiple sets of annular water storage modules 03, combined with on-demand material dispensing by multi-channel rotating columns and multi-tank material supply modules 04, precise filling by multi-piston drive components, and rapid material replenishment by drone-based material dispensing platform 05 and pipeline docking components. This system achieves efficient, precise, and continuous ground support for drone-based high-altitude cleaning operations, significantly improving the automation level and endurance of cleaning operations.

[0022] Furthermore, the multi-channel rotating column includes a rotating column body 032 fixed to the output end of the drive rotating base 031, a plurality of annular water storage modules 03 being annularly opened on the rotating column body 032 for liquid outlet channels 034, and each liquid outlet channel 034 having one end connected upward to the liquid outlet pipe 036, and the other end extending downward into the interior of the corresponding annular water storage module 03 and equipped with a liquid outlet pump 035; and a rotary sealing plug disposed between each annular water storage module 03 and the rotating column body 032.

[0023] like Figure 3 As shown, in the above structure, since the liquid discharge pump 035 is installed at the inlet position of the liquid discharge channel 034 corresponding to the rotating cylinder 032, the liquid discharge channel 034 can always be connected to its corresponding annular water storage module 03 during the rotation of the rotating cylinder 032. The active suction power of the liquid discharge pump 035 ensures smooth liquid supply, while the rotary sealing plug always maintains the sealing and isolation between the channels during the rotation of the rotating cylinder 032, preventing cross-contamination of different levels of medicines and ensuring the reliability and hygiene of independent supply of multiple medicines. It is worth noting that: First, the liquid outlet pump 035 is preferably a metering diaphragm pump, which is connected to the liquid outlet channel 034 and is used to quantitatively transport the liquid in the annular water storage module 03 to the liquid outlet pipe 036. It also has a self-priming function, and its flow end material is resistant to acid and alkali corrosion. Secondly, the drive rotary seat 031 consists of a housing and a motor housed inside the housing, and the output shaft of the motor is fixedly connected to the rotary column 032 through a first coupling. In addition, there are existing mature technologies, which will not be elaborated further.

[0024] Furthermore, the rotating cylinder 032 is also equipped with stirring blades 033 for each of the several sets of annular water storage modules 03, and the stirring blades 033 are used to accelerate the mixing of the liquid inside the several sets of annular water storage modules 03, such as... Figure 3 As shown.

[0025] Example 2 In another embodiment of the present invention, the multi-tank feeding module 04 includes a stand 041 fixed on the upper surface of the base 01; and a plurality of feeding tanks disposed on the top of the stand 041, wherein each feeding tank consists of an upper liquid storage tank 042 and a lower liquid storage tank 043.

[0026] This implementation example Figure 1 , 2 As shown, by setting up multiple sets of supply tanks, the system can simultaneously store a variety of different types or concentrations of cleaning agents, meeting the differentiated liquid requirements of drones in different cleaning scenarios such as glass curtain wall descaling, photovoltaic panel dust removal, and exterior wall paint cleaning.

[0027] Furthermore, the multi-piston drive assembly includes a vertical box 044 fixed to the upper surface of the base 01; several piston mechanisms, each fixed to the top of the vertical box 044 and corresponding to several sets of feeding tanks, each piston mechanism including a piston tube 045, with a piston plate 0451 inside the piston tube 045; a first liquid inlet pipe 046 and a second liquid inlet pipe 047 respectively provided on the upper and lower sides of one side of the piston tube 045, and the ends of the first liquid inlet pipe 046 and the second liquid inlet pipe 047 away from the piston tube 045 respectively connected to their corresponding upper liquid storage tank 042 and lower liquid storage tank 043; and respectively provided on the first liquid inlet pipe 046 and the second liquid inlet pipe 047. 46. ​​A first one-way flow valve and a second one-way flow valve are located inside the second inlet pipe 047 and facing the piston pipe 045; the other side of the piston pipe 045 is also connected to the upper and lower parts of the first outlet pipe 048 and the second outlet pipe 049, respectively, and an extension pipe 0410 is connected to the first outlet pipe 048 and the second outlet pipe 049, and one end of the extension pipe 0410 away from the first outlet pipe 048 and the second outlet pipe 049 is connected to the corresponding annular water storage module 03; it also includes a third one-way flow valve and a fourth one-way flow valve respectively installed in the first outlet pipe 048 and the second outlet pipe 049 and facing the extension pipe 0410.

[0028] It is known, such as Figure 1 As shown, each piston mechanism corresponds to one of the feeding tanks. Each piston mechanism has a piston plate 0451 inside its piston tube 045. A first inlet pipe 046 and a second inlet pipe 047 are respectively located on the upper and lower sides of one side of the piston tube 045, while a first outlet pipe 048 and a second outlet pipe 049 are respectively connected to the upper and lower sides of the other side. The first outlet pipe 048 and the second outlet pipe 049 are connected to their corresponding annular water storage module 03 via extension pipes 0410. This piston-type metering structure, through the reciprocating motion of the piston plate 0451, can simultaneously extract two liquids from the upper and lower storage tanks 043 in one suction stroke, and simultaneously inject the mixed liquid into the annular water storage module 03 in one pushing stroke. This achieves synchronous feeding and mixing of the two storage tanks, improving the efficiency of drug preparation. It is worth noting that: First, if multiple sets of supply tanks store cleaning agents of different concentrations, the same flow rate of cleaning solution can be obtained for each water storage layer by controlling the opening degree of each one-way flow valve; if the same concentration of cleaning agent is stored, the differentiated solution ratio of different water storage layers can also be achieved by controlling the opening size of each one-way flow valve.

[0029] Secondly, the arrangement of the one-way flow valves ensures the uniqueness of the liquid flow direction, prevents backflow and cross-contamination, and guarantees the accuracy of the filling amount and the reliability of the system operation. Moreover, the one-way flow valve here is preferably a proportional one-way flow valve. This type of valve receives continuously changing electrical signals to drive the internal proportional electromagnet, so that the electromagnetic force and elastic force generated by it are balanced, thereby precisely controlling the opening size of the valve core. At this time, under the same piston suction power, different ratios of drug concentration can be achieved. Specifically, several groups of feeding tanks can be filled with the same or different drugs. Through the above flow control, the drug filling amount of each water storage module can be independently adjusted, realizing flexible control of different levels of drug ratio.

[0030] Furthermore, a cam drive mechanism is assembled inside the vertical housing 044 and used to drive several piston mechanisms to perform suction motion. The cam drive mechanism includes a connecting shaft 0411 horizontally installed inside the vertical housing 044, several sets of cam bodies 0412 fixed to the connecting shaft 0411, and a rotating shaft 0413 eccentrically installed between two cam bodies 0412 in each set; a piston rod 0414 connected to the rotating shaft 0413, one end of the piston rod 0414 away from the rotating shaft 0413 extending into the corresponding piston tube 045 and provided with a hinge 0417, and the hinge 0417 is hinged to the corresponding piston plate 0451 by a pin; and a drive motor 0415 provided on the surface of the base 01, the output shaft of the drive motor 0415 is provided with a second coupling 0416, and the second coupling 0416 is connected to the end of the connecting shaft 0411. When the drive motor 0415 is running, the second coupling 0416 can drive the connecting shaft 0411 to rotate.

[0031] like Figure 4 , 5 As shown in Figures 6, 7, and 8, this cam drive structure drives the connecting shaft 0411 to rotate through a single drive motor 0415. Several sets of cam bodies 0412 on the connecting shaft 0411 simultaneously drive the corresponding piston mechanism to reciprocate, realizing the efficient linkage of one power source synchronously driving multiple pistons, while ensuring the consistency of the actions of each piston mechanism. The eccentrically positioned connecting block 0513, such as Figure 5 As shown, the piston plate 0451 and piston rod 0414, which are hinged by the hinge member 0417, convert the rotational motion into linear reciprocating motion, resulting in high transmission efficiency and compact structure.

[0032] Furthermore, a flexible connecting part 0418 is provided between the bottom of each piston tube 045 and its corresponding piston rod 0414, such as... Figure 5 , 6 As shown, this structure allows the piston rod 0414 to move up and down and deflect while simultaneously ensuring the sealed isolation between the piston tube 045 and the vertical box 044.

[0033] Furthermore, the water supply steel pipe includes a main steel pipe 02 fixed on the upper surface of the base 01, one end of the main steel pipe 02 being connected to a water pump 023 installed on the surface of the base 01, and the other end being sealed; and several side steel pipes 021 connected to the upper part of the main steel pipe 02, corresponding to several sets of annular water storage modules 03, and each side steel pipe 021 having one end away from the main steel pipe 02 connected to its corresponding annular water storage module 03 and having a control valve body 022 inside.

[0034] like Figure 1 , 3 As shown in Figures 4, 6, and 7, this tree-like water supply structure distributes clean water to the side steel pipes 021 of each layer through the vertical main steel pipe 02, ensuring an independent water supply channel for each ring-shaped water storage module 03. Furthermore, the control valve body 022 in each side steel pipe 021 can be selected as a solenoid valve or an electric ball valve, which is electrically connected to the control module. The control module controls the opening, closing and opening degree of each control valve body (022) according to the liquid level signal in each annular water storage module (03), so that the system can flexibly replenish water according to the consumption of each layer of liquid during the cleaning process, realize the decoupling control of clean water supply and drug preparation, and improve the system operation flexibility.

[0035] Example 3 In another embodiment of the present invention, the drone feeding platform 05 includes a support 051; a landing base, which is disposed on one side of the support 051. The landing pad includes a horizontal plate 052 slidably mounted on the surface of the support 051, an upright plate 053 fixed to the horizontal plate 052, and a connecting pipe 054 that extends horizontally through the upright plate 053. A drone docking port 056 is provided at one end of the connecting pipe 054, which can dock and communicate with the drone's feeding interface, and an elastic docking port 055 is provided at the other end, which can dock with the liquid outlet pipe 036.

[0036] like Figure 1 , 9 As shown in Figure 10, the UAV docking port 056 at one end of the connecting pipe 054 can dock with the UAV's injection interface, and the flexible docking port 055 at the other end can dock with the liquid outlet pipe 036. Together with the pipe docking assembly, the UAV feeding can be quickly connected. Among them, the sliding installation of the horizontal plate 052 and the support 051 allows the feeding platform to move horizontally, which on the one hand realizes the docking of the flexible docking port 055 and the liquid outlet pipe 036, and the flexible docking port 055 provides flexible compensation during docking, which reduces the docking accuracy requirements and improves the success rate and convenience of feeding operation. On the other hand, it drives the self-locking and unlocking of the pipeline connection components to ensure the stable operation of the feeding process.

[0037] Furthermore, the pipe connection assembly includes a grooved frame 057 fixed to the other side of the support 051; a slide rail slider assembly, which includes a horizontal rail 058 internally disposed in the grooved frame 057 near the stop seat, and a slider body 059 slidably mounted to the horizontal rail 058, and the slider body 059 being fixedly connected to the horizontal plate 052; and a push hook lock assembly, which includes a connecting base plate 0517 internally disposed in the middle of the grooved frame 057 and connected to the slider body 059, and a side branch channel 0510 and a main direct current channel 0511 opened on the surface of the connecting base plate 0517, wherein the side branch channel 0510, one end of the main direct current channel 0511 is connected to form an h-shaped groove structure, and the other end converges to form an inverted V-shaped card slot 0512; and an end block 0515 is fixed to one end of the groove frame 057 near the annular water storage module 03, with a steel wire hook post 0516 connected to the end block 0515, and the hook part of the steel wire hook post 0516 can slide inside the side branch channel 0510 and the main direct current channel 0511; it also includes a connecting block 0513 fixed to the connecting base plate 0517, and a spring 0514 is connected to the end of the groove frame 057 away from the annular water storage module 03.

[0038] like Figure 9 , 10 As shown in Figure 11, this pipe connection assembly includes a slide rail slider assembly (the horizontal rail 058 and the slider body 059 slide together) and a push hook lock assembly (the side branch channel 0510 and the main direct channel 0511 are formed into an h-shaped groove on the surface of the connecting base plate 0517, and the ends converge to form an inverted V-shaped locking groove 0512. The hook part of the steel wire hook column 0516 on the end block 0515 can slide in the groove. The connecting block 0513 and the groove frame 057 are connected to a spring 0514 at the end away from the annular water storage module 03). The above design guides the sliding path of the wire hook column 0516 within the H-shaped trough, achieving automatic sequential control of the feeding platform's advancement, docking, and locking. Specifically, when the drone lands on the surface of the horizontal plate 052 and pushes the vertical plate 053 closer to the liquid outlet pipe 036, the entire H-shaped trough moves closer to the wire hook column 0516. During this process, the wire hook column 0516 slides along the side channel 0510 to the inverted V-shaped locking groove 0512 and automatically engages and locks, maintaining a stable docking state. Due to the elastic characteristics of the elastic docking port 055, as the drone further approaches the liquid outlet pipe 036, the hook of the wire hook column 0516 can slide past the inverted V-shaped locking groove 0512 and enter the main direct current channel 0511. At this time, the spring 0514 provides a reset force, causing the feeding platform to automatically return to its initial position.

[0039] It is worth noting that: In order to ensure the precise docking of the flexible docking port 055 with the corresponding liquid outlet pipe 036, the present invention provides a first pressure sensor on the surface of the horizontal plate 052. When the first pressure sensor receives pressure information, the drone moves forward and pushes the vertical plate 053 under the action of the control module. When the pressure value received by the second pressure sensor in the flexible docking port 055 reaches the preset value, the drone stops moving forward. At this time, the steel wire hook column 0516 is inserted into the inverted V-shaped locking groove 0512, and the liquid injection operation is performed at the same time. When the liquid level sensor in the UAV's onboard liquid tank reaches the set value, the UAV further pushes the upright plate 053. At this time, the steel wire hook column 0516 disengages and enters the main DC channel 0511, achieving automatic reset, and the UAV resumes flight.

For example, they can refer to a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.
