Description

Technical Field

[0001] This application relates to the field of robotics, and more specifically, to a component and system for lifting and filling liquids. Background Technology

[0002] With the development of science and technology, robots are being used more and more widely in the field of high-altitude operations, gradually becoming an important alternative to manual labor. In some high-altitude operation scenarios, it is often necessary to use lifting equipment to hoist the robot and move it to the work area so that the robot can work within that area. At the same time, when the robot's consumables (such as water, cleaning fluid, etc.) are about to run out, they need to be replenished in a timely manner so that the robot can continue to work.

[0003] However, current lifting equipment is generally only suitable for robot handling; moving the robot to the ground for liquid refilling would reduce work efficiency. Using two separate sets of equipment for lifting and liquid refilling would increase the complexity of the equipment. Therefore, how to achieve both lifting and liquid refilling functions within a single structure remains a problem that needs to be solved. Utility Model Content

[0004] This application provides a component and system for lifting and filling liquids, which can realize both lifting functions and meet the needs of filling liquids in the same structure.

[0005] In a first aspect, a component for hoisting and filling liquid is provided, comprising: a main body, the main body including a side wall, the side wall forming a hollow structure having an opening at one end in a first direction, the side wall having a through hole, and the main body having a discharge hole at the other end opposite to the opening in the first direction; a movable joint, the movable joint being accommodated in the hollow structure, the movable joint having a groove at a position corresponding to the through hole, the opening of the groove facing the through hole, the movable joint having a filling channel penetrating the movable joint in the first direction, the filling channel communicating with the discharge hole; and a fixing part, the fixing part being connected to the main body and capable of passing through the through hole and the groove.

[0006] The hoisting and liquid filling components provided in this application embodiment can realize the functions of hoisting the working device and filling the working device with liquid through the same set of structures. This can reduce the structural complexity of the hoisting and liquid filling components, and can also replenish the working device with the required liquid without leaving the working area, thereby improving the working efficiency of the working device.

[0007] In some embodiments, the component includes a seal disposed between the movable joint and the body portion, and filling the gap between the movable joint and the body portion in a plane perpendicular to the first direction.

[0008] By sealing the gap between the movable joint and the main body with a sealant, the possibility of liquid leakage can be reduced during the liquid filling process of the working device, the efficiency of liquid filling can be improved, and the circuit structure of the working device can also be protected, thereby improving the reliability of the working device.

[0009] In some embodiments, the seal is disposed in the surrounding area of ​​the filling channel on the side opposite to the opening of the body portion in the first direction, and at least a portion of the seal is disposed around the movable joint.

[0010] This structure can seal the movable joint and sidewalls near the outlet of the filling channel. On the one hand, it can improve the stability of the movable joint in the hollow structure, and on the other hand, it can make the movable joint tightly press against the seal, reducing the possibility of leakage of the filling liquid.

[0011] In some embodiments, the main body includes a boss that protrudes from the sidewall toward the hollow structure in a second direction, is disposed on the side of the movable joint opposite to the opening of the main body in the first direction, and is capable of supporting the movable joint. At least a portion of the seal is disposed between the movable joint and the boss, and the second direction is perpendicular to the first direction.

[0012] The boss and the seal provided on the boss can support the movable joint in the first direction. The seal is pressed together by a part of the gravity and the pressure of the fixed part on the movable joint, so that the movable joint and the seal can be in close contact in the first direction, thereby improving the sealing performance between the movable joint and the main body.

[0013] In some embodiments, the main body includes a liquid outlet, a discharge hole is disposed on the liquid outlet, the liquid outlet is connected to the side wall and communicates with the discharge hole and the filling channel.

[0014] The liquid outlet port enables effective connection between the component and the working device, allowing for liquid refilling between them. This port facilitates quick and flexible assembly and disassembly of the component and the working device, enabling replacement or maintenance in different operating scenarios and allowing for component reuse. This improves the component's versatility and economy, reducing its operating costs.

[0015] In some embodiments, the fixing part has a first inclined surface on the side opposite to the opening of the main body in a first direction, and the first inclined surface is inclined from the side of the fixing part that enters the through hole and the groove in a direction opposite to the opening of the main body.

[0016] The first inclined surface makes it easier for the fixing part to pass through the through hole and groove, and presses down on the movable joint when it is moved into place, so that the movable joint can make close contact with the main body. On the one hand, it improves the stability of the connection between the movable joint and the main body during hoisting, and on the other hand, it can reduce the gap between the movable joint and the main body, which is conducive to the directional flow of liquid during the liquid filling process.

[0017] In some embodiments, the groove has a second inclined surface, the second inclined surface having the same inclination direction as the first inclined surface.

[0018] The second inclined surface cooperates with the first inclined surface to better guide the fixing part through the groove. Even if the moving path of the fixing part deviates from the groove within a certain range, the fixing part can still pass through the groove and fix the movable joint and the main body, thereby improving the overall reliability and stability of the assembly.

[0019] In some embodiments, the fixing part includes a push rod and a pin, the pin being able to pass through the through hole and the groove, the push rod being connected to the pin for controlling the pin to enter the through hole and the groove, or to disengage from the through hole and the groove.

[0020] By controlling the reciprocating motion of the push rod, the pin can be controlled to enter and exit the through hole and groove, and the locking and unlocking between the movable joint and the main body can be achieved through electric control.

[0021] In some embodiments, the fixing part includes a sensor disposed on the side wall, located in a region of the through hole on the side opposite to the opening of the main body in the first direction, and within the projection range of the movable joint on the side wall.

[0022] By sensing the movable joint with sensors, automatic control of the push rod can be achieved when the movable joint is adjusted into place. This helps to improve the automation and accuracy of the operation, reduce manual intervention, lower the difficulty of operation and the error rate, and thus improve the overall efficiency and reliability of the component.

[0023] In some embodiments, the cross-sectional area formed by the sidewall enclosing the opening of the main body is greater than the cross-sectional area formed by the sidewall enclosing the other end opposite to the opening in the first direction.

[0024] The sidewall is formed into a funnel-shaped opening in the first direction, which helps guide the movable joint into the hollow structure enclosed by the sidewall, providing a wider entry path for the movable joint and reducing the difficulty of aligning the movable joint with the opening of the main body.

[0025] In some embodiments, the movable joint includes a lifting section for connection to a transport mechanism.

[0026] The hoisting unit enables the transport mechanism to hoist components and operating devices, allowing the transport mechanism to firmly grip and support the operating devices through movable joints, thereby improving the versatility and adaptability of the components.

[0027] In some embodiments, the component includes: a flexible base connected to the main body and disposed at the other end of the main body opposite to the opening of the main body.

[0028] The flexible base acts as a buffer when the main body rests on the surface of the lifting device, reducing rigid collisions between the two and absorbing impact energy. This reduces potential damage to the lifting device during lifting and lowering, improving the safety and reliability of the lifting process. Simultaneously, the flexible base reduces the requirements for the flatness of the lifting device surface, increasing the adaptability of the components in different application scenarios.

[0029] In some embodiments, the component includes: a traction rope, one end of which is connected to the main body and the other end of which is connected to a working device; and a traction spring, one end of which is connected to a first connection point of the traction rope and the other end of which is connected to a second connection point of the traction rope, wherein the first connection point and the second connection point are located between one end and the other end of the traction rope, and the length of the traction rope between the first connection point and the second connection point is greater than the length of the traction spring when it is not under force.

[0030] On the one hand, the traction rope and traction spring allow the component to leave the working device during the lifting process, especially when the working surface where the working device is located has a certain angle with the horizontal plane. This provides some space for the angle adjustment of the component, so that the first direction of the component is adjusted to be parallel to the direction of gravity before the working device is lifted. This reduces the interaction force that may be generated between the component and the working device, thereby reducing the damage that the lifting operation may cause to the working device and the component.

[0031] On the other hand, the traction spring can store the traction rope when the component is placed on the working device, so that the connection between the component and the working device is as taut as possible, and the opening of the main body is oriented in a certain direction, so that it is not easy to shake.

[0032] In a second aspect, a system for lifting and filling liquids is provided, comprising: a transport mechanism; a working device; and a component for lifting and filling liquids as described in any embodiment of the first aspect above, wherein the transport mechanism is connected to the movable joint, and the main body is connected to the working device.

[0033] The hoisting and liquid filling system provided in this application embodiment can realize the functions of hoisting the working device and filling the working device with liquid in the same structure, which can reduce system complexity and improve work efficiency.

[0034] In some embodiments, the working device includes a liquid storage tank with an inlet port, and the system includes: a first filling pipe connected to the filling channel of the movable joint and the liquid to be filled; and a second filling pipe connected to the discharge port of the main body and the inlet port of the working device.

[0035] The first and second filling pipes provide a channel from the liquid to be filled to the liquid storage tank of the working device, allowing for timely replenishment when the liquid carried by the working device is about to run out. Furthermore, the reuse of the lifting structure for liquid filling reduces system complexity and allows for replenishment of the working device without leaving the work area, thus improving its operational efficiency.

[0049] The component for hoisting and adding liquid provided in this application embodiment can be applied to fields such as drone hoisting and crane hoisting. Specifically, it can be used, for example, in the scenario of photovoltaic panel cleaning to realize the hoisting of cleaning robots and the addition of cleaning fluid and / or water.

[0050] The lifting and liquid filling component 1 provided in this application embodiment is typically used in conjunction with the transport mechanism 60 and the working device 70. The transport mechanism 60 is connected to the working device 70 through the lifting and liquid filling component 1 to lift the working device 70 or to fill the working device 70 with liquid.

[0051] Specifically, Figure 1 The diagram shown is a schematic structure of a component 1 for hoisting and refilling liquids according to an embodiment of this application. Figure 2 yes Figure 1 A schematic diagram of the exploded structure in the image, such as... Figure 1 and Figure 2 As shown, the hoisting and liquid filling component 1 provided in this application embodiment includes a main body 10, a movable joint 20, and a fixed part 30.

[0052] The main body 10 includes a side wall 11, which encloses a hollow structure having an opening at one end in the first direction X. A through hole 13 is provided on the side wall 11, and a discharge hole 14 is provided at the other end of the main body 10 opposite to the opening 12 in the first direction X.

[0053] The movable joint 20 can be accommodated in the hollow structure. A groove 21 is provided on the movable joint 20 at the position corresponding to the through hole 13. The opening of the groove 21 faces the through hole 13. The movable joint 20 is provided with a filling channel 22. The filling channel 22 passes through the movable joint 20 in the first direction X and communicates with the discharge hole 14.

[0054] The fixing part 30 is connected to the main body part 10 and can pass through the through hole 13 and the groove 21.

[0055] The main body 10 refers to the outer shell portion of component 1. The main body 10 is a hollow structure, enclosed by side walls 11, and has an opening at one end in the first direction X. The opening 12 of the main body 10 allows the movable connector 20 to enter or exit the hollow structure of the main body 10. A discharge hole 14 is provided at the other end of the main body 10 opposite to the opening 12 in the first direction X. Specifically, the discharge hole 14 may be located on the side wall 11 in a region near this other end. In one embodiment, the main body 10 may include a bottom wall, which, together with the side walls 11, forms a hollow structure with an opening at one end in the first direction X. The discharge hole 14 may be located on the bottom wall.

[0056] The movable joint 20 can enter or detach from the hollow structure of the main body 10 to connect the transport mechanism 60 and the component 1. The movable joint 20 is provided with a groove 21. When the movable joint 20 is accommodated in the hollow structure, the groove 21 is positioned opposite to the through hole 13 provided on the side wall 11 of the main body 10; that is, the groove 21 and the through hole 13 can together form a connected accommodating space. In one embodiment, the groove 21 of the movable joint 20 can surround the movable joint 20 to reduce the alignment accuracy required for alignment with the through hole 13 on the side wall 11.

[0057] The filling channel 22 is a structure on the movable joint 20 that provides a flow path for the liquid being filled, and it communicates with the discharge port 14. During the process of filling the working device 70 with liquid, one end of the filling channel 22 facing the opening 12 of the main body 10 in the first direction X serves as the liquid inlet, and the other end serves as the liquid outlet of the movable joint 20. The liquid further flows towards the discharge port 14 and is then filled into the working device 70 through the discharge port 14. The filling channel 22 extends in the first direction X and passes through the movable joint 20. In some embodiments, the filling channel 22 may pass through the center of the movable joint 20.

[0058] The fixing part 30 refers to the structure that relatively fixes the main body 10 and the movable joint 20. The fixing part 30 can be a long strip structure that passes through the through hole 13 of the main body 10 in the second direction Y and is partially accommodated in the groove 21 of the movable joint 20. The second direction Y is perpendicular to the first direction X. In some embodiments, the second direction Y is parallel to the extension direction of the fixing part 30. The bottom of the groove 21 is engaged with the fixing part 30. The fixing part 30 is connected to the main body 10. When the transport mechanism 60 lifts the movable joint 20, it can lift the entire assembly 1 through the engagement between the movable joint 20 and the fixing part 30. The fixing part 30 can be symmetrically arranged on both sides of the main body 10 in the second direction Y. Correspondingly, the through hole 13 on the main body 10 and the groove 21 on the movable joint 20 are also symmetrically arranged, so that the fixing part 30 can provide more stable support for the lifting operation when passing through the through hole 13 and the groove 21.

[0059] The hoisting and liquid filling component 1 provided in this application embodiment can realize the functions of hoisting the working device 70 and filling the working device 70 with liquid through the same structure. This can reduce the structural complexity of the hoisting and liquid filling component 1, and can also replenish the working device 70 with the required liquid without leaving the working area, thereby improving the working efficiency of the working device 70.

[0060] According to some embodiments of this application, component 1 includes a seal 40 disposed between the movable joint 20 and the main body 10, and filling the gap between the movable joint 20 and the main body 10 in a plane perpendicular to the first direction X.

[0061] The seal 40 is a structure that seals the gap between the movable joint 20 and the main body 10 when the movable joint 20 is housed within the hollow structure of the main body 10. Since the movable joint 20 and the main body 10 are two separate structures, when liquid is added to the filling channel 22 while it is connected to the discharge port 14, the liquid may overflow from the gap between the movable joint 20 and the main body 10. Therefore, the seal 40 is provided between the movable joint 20 and the main body 10 to prevent the added liquid from leaking out.

[0062] Considering that the liquid being filled usually flows along the first direction X from the side of the movable joint 20 facing the opening 12 of the main body 10 to the side away from the opening 12 of the main body 10, filling the gap between the movable joint 20 and the main body 10 in a plane perpendicular to the first direction X can prevent the liquid from overflowing along the gap after flowing out of the outlet of the filling channel 22, which is beneficial to guiding the liquid being filled to the discharge hole 14.

[0063] By sealing the gap between the movable joint 20 and the main body 10 with the sealing element 40, the possibility of liquid leakage can be reduced during the process of adding liquid to the working device 70, the efficiency of adding liquid can be improved, and the circuit structure of the working device 70 can also be protected, thereby improving the reliability of the working device 70.

[0064] According to some embodiments of this application, a seal 40 is disposed in the surrounding area of ​​the filling channel 22 on the side opposite to the opening 12 of the main body 10 in the first direction X, and at least a portion of the seal 40 is disposed around the movable joint 20.

[0065] In one specific implementation, such as Figure 4 As shown, at least a portion of the seal 40 is disposed on the side of the movable joint 20, that is, on the surface of the movable joint 20 opposite to the side wall 11. The side of the filling channel 22 facing the opening 12 of the main body 10 in the first direction X is the liquid inlet position, and the side of the filling channel 22 away from the opening 12 of the main body 10 in the first direction X is the outlet position of the filling channel 22. The seal 40 fills the gap between the movable joint 20 and the side wall 11 near the outlet position of the filling channel 22.

[0066] At least a portion of the seal 40 may surround the side of the movable joint 20, thereby reducing the possibility of liquid leakage from the side by sealing the side portion of the movable joint 20 to the side wall 11. In some embodiments, the seal 40 may further include a portion disposed on the bottom surface of the movable joint 20 to enhance the sealing performance between the movable joint 20 and the main body 10. The bottom surface of the movable joint 20 is perpendicular to the first direction X and is located on the side of the movable joint 20 opposite to the opening 12 of the main body 10.

[0067] This structure can seal the movable joint 20 and the side wall 11 near the outlet of the filling channel 22. On the one hand, it can improve the stability of the movable joint 20 in the hollow structure, and on the other hand, it can make the movable joint 20 tightly press against the seal 40, reducing the possibility of leakage of the filled liquid.

[0068] According to some embodiments of this application, the main body 10 includes a boss 15, which protrudes from the side wall 11 toward the hollow structure in the second direction Y and is disposed on the side of the movable joint 20 away from the opening 12 of the main body 10 along the first direction X. It is capable of supporting the movable joint 20, and at least a portion of the seal 40 is disposed between the movable joint 20 and the boss 15. The second direction Y is perpendicular to the first direction X.

[0069] In another specific implementation, such as Figure 5As shown, a boss 15 may be provided on the inner side of the side wall 11 of the main body 10. The boss 15 protrudes from the side wall 11 along the second direction Y on the inner side of the side wall 11, forming a stepped structure with the side wall 11. The movable joint 20 is supported on the boss 15 when it is housed in the hollow structure.

[0070] In some embodiments, the portion of the movable connector 20 located in the groove 21 opposite to the main body 10 in the first direction X mates with the boss 15, and the seal 40 provides a seal in the region between the outlet of the filling channel 22 and the groove 21. Further, the boss 15 may be disposed opposite to the bottom surface of the movable connector 20, in which case at least a portion of the seal 40 is disposed between the boss 15 and the bottom surface of the movable connector 20.

[0071] At least a portion of the seal 40 is disposed between the movable joint 20 and the boss 15. That is, when the movable joint 20 is supported by the boss 15, it can press against the seal 40 between the movable joint 20 and the boss 15. In some embodiments, when the fixing part 30 engages the movable joint 20 and the main body 10, it can generate a certain downward pressure on the movable joint 20, increasing the compressive force between the movable joint 20 and the seal 40 in the first direction X, thereby improving the sealing degree between the movable joint 20 and the boss 15.

[0072] The boss 15 and the sealing element 40 provided on the boss 15 can support the movable joint 20 in the first direction X. The sealing element 40 is pressed together by a part of the gravity and the pressure of the fixed part 30 on the movable joint 20, so that the movable joint 20 and the sealing element 40 can be in close contact in the first direction X, thereby improving the sealing performance between the movable joint 20 and the main body 10.

[0073] According to some embodiments of this application, the main body 10 includes a liquid outlet 16, a discharge hole 14 is disposed on the liquid outlet 16, the liquid outlet 16 is connected to the side wall 11, and communicates with the discharge hole 14 and the filling channel 22.

[0074] like Figures 1 to 5 As shown, the liquid outlet 16 refers to the structure on component 1 for connecting to the liquid storage tank 71 of the working device 70. The liquid outlet 16 may have a cavity that connects the filling channel 22 and the discharge port 14. In some embodiments, the liquid outlet 16 may be a structure formed by a side wall and a bottom wall, wherein the discharge port 14 may be provided on the side wall or the bottom wall of the liquid outlet 16. Optionally, the liquid outlet 16 may only include a side wall, which forms a cavity. One end of the liquid outlet 16 is open and communicates with the hollow structure of the main body 10, and the other end is open as the discharge port 14.

[0075] The liquid outlet 16 enables effective connection between component 1 and the working device 70, allowing both components to be filled with liquid. Through the liquid outlet 16, component 1 and the working device 70 can be quickly and flexibly disassembled and assembled, facilitating replacement or maintenance in different operating scenarios, enabling the reuse of component 1, thereby improving its versatility and economy, and reducing its operating costs.

[0076] According to some embodiments of this application, the fixing part 30 has a first inclined surface 301 on the side away from the opening 12 of the main body part 10 in the first direction X. The first inclined surface 301 is inclined from the side of the fixing part 30 that enters the through hole 13 and the groove 21 in the direction away from the opening 12 of the main body part 10.

[0077] like Figures 3 to 5 As shown, the portion of the fixing part 30 that can pass through the through hole 13 and the groove 21 has a first inclined surface 301. The first inclined surface 301 is located on the side of the fixing part 30 facing away from the opening 12 of the main body part 10 in the first direction X. The fixing part 30 is generally wedge-shaped, with a smaller cross-sectional area at the end that first enters the through hole 13 and the groove 21, and a larger cross-sectional area at the end that subsequently enters the through hole 13 and the groove 21. This allows the fixing part 30 to not require too high alignment accuracy when it first enters the through hole 13 and the groove 21, and to contact the wall of the groove 21 when it subsequently enters the through hole 13 and the groove 21, thus pressing the movable joint 20 against the main body part 10.

[0078] The first inclined surface 301 makes it easier for the fixed part 30 to pass through the through hole 13 and the groove 21, and presses down on the movable joint 20 when it is moved into place, so that the movable joint 20 can make close contact with the main body 10. On the one hand, it improves the stability of the connection between the movable joint 20 and the main body 10 during hoisting, and on the other hand, it can reduce the gap between the movable joint 20 and the main body 10, which is conducive to the directional flow of liquid during the liquid filling process.

[0079] According to some embodiments of this application, the groove 21 has a second inclined surface 211, which contacts the first inclined surface 301 and has the same inclination direction as the first inclined surface 301.

[0080] like Figures 3 to 5 As shown, the opening of the groove 21 faces the second direction Y, and the second inclined surface 211 can be provided on the wall surface of the groove 21 that intersects the first direction X and is away from the opening 12 of the main body 10. The second inclined surface 211 has the same inclination direction as the first inclined surface 301, and the first inclined surface 301 contacts the second inclined surface 211 when the fixing part 30 is pushed into the groove 21.

[0081] The second inclined surface 211 cooperates with the first inclined surface 301 to better guide the fixing part 30 through the groove 21. Even if the moving path of the fixing part 30 deviates from the groove 21 within a certain range, the fixing part 30 can still pass through the groove 21 and fix the movable joint 20 and the main body 10, thereby improving the overall reliability and stability of the assembly 1.

[0082] According to some embodiments of this application, the fixing part 30 includes a push rod 31 and a pin 32. The pin 32 can pass through the through hole 13 and the groove 21. The push rod 31 is connected to the pin 32 and is used to control the pin 32 to enter the through hole 13 and the groove 21, or to disengage from the through hole 13 and the groove 21.

[0083] like Figures 1 to 5 As shown, the fixing part 30 can be electrically controlled to enter or disengage from the through hole 13 and the groove 21. Specifically, the fixing part 30 includes a push rod 31 and a pin 32, wherein the push rod 31 can be, for example, an electric push rod 31; the pin 32 is connected to a movable part on the push rod 31 and moves with the back-and-forth movement of the push rod 31. The push rod 31 can be located on the outside of the main body 10, and the pin 32 is positioned corresponding to the through hole 13. When the push rod 31 moves back and forth on the outside of the main body 10, the pin 32 can move back and forth in the channel formed by the through hole 13 and the groove 21, thereby locking and unlocking the movable joint 20 with the main body 10.

[0084] By controlling the reciprocating motion of the push rod 31 to control the entry and exit of the pin 32 in the through hole 13 and the groove 21, the locking and unlocking between the movable joint 20 and the main body 10 can be achieved by electric control.

[0085] According to some embodiments of this application, the fixing part 30 includes a sensor 33, which is disposed on the side wall 11, located in the region of the through hole 13 on the side opposite to the opening 12 of the main body part 10 along the first direction X, and located within the projection range of the movable joint 20 on the side wall 11.

[0086] like Figure 1 and Figure 2 As shown, sensor 33 refers to the structure in component 1 used to sense whether the movable joint 20 has moved into place. Specifically, when the movable joint 20 falls into the hollow structure and the groove 21 of the movable joint 20 is substantially aligned with the through hole 13, the sensing element of sensor 33 is triggered. Sensor 33 sends a signal to push rod 31 to control push rod 31 to start. Thus, push rod 31 drives pin 32 into the channel formed by through hole 13 and groove 21 to fix movable joint 20 and main body 10.

[0087] Sensor 33 is typically positioned within the projection range of the movable connector 20 onto the side wall 11 to ensure that the movable connector 20 can trigger the operation of sensor 33. Simultaneously, to ensure that sensor 33 is triggered only when the groove 21 of the movable connector 20 is substantially aligned with the through hole 13, the sensing element of sensor 33 is positioned below the through hole 13, specifically in the area of ​​the through hole 13 along the first direction X opposite to the opening 12 of the main body 10.

[0088] By sensing the movable joint 20 through the sensor 33, the push rod 31 can be automatically controlled when the movable joint 20 is adjusted into place. This helps to improve the automation and accuracy of the operation, reduce manual intervention, reduce the difficulty of operation and the error rate, and thus improve the overall efficiency and reliability of component 1.

[0089] According to some embodiments of this application, the cross-sectional area formed by the sidewall 11 enclosing the opening 12 of the main body 10 is greater than the cross-sectional area formed by the sidewall 11 enclosing the other end opposite to the opening in the first direction X.

[0090] like Figure 1 and Figure 2 As shown, the sidewalls 11 of the main body 10 enclose a hollow structure with an opening at one end. The cross-sectional area formed by the sidewalls 11 at the opening is greater than the cross-sectional area formed by the sidewalls 11 at other locations. The cross-sectional area formed by the sidewalls 11 refers to the area enclosed in a plane perpendicular to the first direction X. In some embodiments, the cross-sectional area formed by the sidewalls 11 can gradually decrease from the opening along the first direction X, thus forming a slope on the sidewalls 11. This reduces the alignment accuracy of the movable joint 20 by a larger opening, and guides the movable joint 20 into the hollow structure by the slope.

[0091] The side wall 11 forms a flared opening in the first direction X, which helps guide the movable joint 20 into the hollow structure enclosed by the side wall 11, providing a wider entry path for the movable joint 20 and reducing the difficulty of aligning the movable joint 20 with the opening 12 of the main body 10.

[0092] According to some embodiments of this application, the movable joint 20 includes a lifting part 23 for connection with the transport mechanism 60.

[0093] The lifting section 23 can be a lifting lug on the movable joint 20, with a through hole. Taking the movable joint 20 connected to the transport mechanism 60 via a wire rope as an example, one end of the wire rope can pass through the through hole on the lifting lug, and the other end is connected to the transport mechanism 60. The transport mechanism 60 lifts the movable joint 20 and transports it to the hollow structure of the main body 10. With the movable joint 20 locked to the main body 10, the movable joint 20 and the main body 10 are lifted together, thereby realizing the lifting of the working device 70 connected to the main body 10.

[0094] The hoisting unit 23 enables the transport mechanism 60 to hoist the component 1 and the working device 70, allowing the transport mechanism 60 to firmly grip and support the working device 70 through the movable joint 20, thereby improving the versatility and adaptability of the component 1.

[0095] According to some embodiments of this application, component 1 includes a flexible base 50, which is connected to the main body 10 and disposed at the other end of the main body 10 opposite to the opening.

[0096] by Figure 6 For example, the flexible base 50 can be, for instance, a sponge, wrapped around the bottom of the main body 10, that is, the end of the main body 10 opposite to the opening 12 of the main body 10 in the first direction X. In some embodiments, this end of the main body 10 is provided with a discharge hole 14, and the flexible base 50 can be positioned to avoid the location of the discharge hole 14.

[0097] The flexible base 50 acts as a buffer when the main body 10 lands on the surface of the working device 70, reducing rigid collisions between the two, absorbing impact energy, and mitigating potential damage to the working device 70 during lifting and lowering, thereby improving the safety and reliability of the lifting process. Simultaneously, the flexible base 50 also reduces the requirements for the flatness of the working device 70 surface, improving the adaptability of component 1 in different application scenarios.

[0098] According to some embodiments of this application, component 1 includes a traction rope 81, one end of which is connected to the main body 10 and the other end is used to connect to the working device 70; and a traction spring 82, one end of which is connected to a first connection point 821 of the traction rope 81 and the other end of which is connected to a second connection point 822 of the traction rope 81. The first connection point 821 and the second connection point 822 are located between one end and the other end of the traction rope 81, and the length of the traction rope 81 between the first connection point 821 and the second connection point 822 is greater than the length of the traction spring 82 when it is not under force.

[0099] The first connection point 821 and the second connection point 822 of the traction rope 81 are located between the end of the traction rope 81 connected to the main body 10 and the other end connected to the working device 70. The first connection point 821 and the second connection point 822 are respectively connected to the two ends of the spring, and the length of the traction rope 81 between the first connection point 821 and the second connection point 822 is greater than the length of the spring when it is not under stress. At the same time, when the component 1 is supported on the working device 70, the traction rope 81 and the traction spring 82 can keep the connection between the component 1 and the working device 70 in a taut state, so that the component 1 can be stably supported on the working device 70 and is not easily changed in position or overturned by the slack traction rope 81.

[0100] When the spring is stretched, the traction rope 81 between the first connection point 821 and the second connection point 822 is also straightened accordingly, providing space for the lifting and adjustment of component 1. At the same time, during the lifting process, the length of the traction rope 81 can be adjusted according to the force conditions, thereby adjusting the angle between component 1 and the working device 70 during the lifting process; when the spring is not stretched, the traction spring 82 can retract the traction rope 81 between the first connection point 821 and the second connection point 822.

[0101] On the one hand, the traction rope 81 and traction spring 82 allow the component 1 to leave the working device 70 during the lifting process, especially when the working surface where the working device 70 is located has a certain angle with the horizontal plane, providing a certain space for the angle adjustment of the component 1, so that the first direction X of the component 1 is adjusted to be parallel to the direction of gravity, and then the working device 70 is lifted, reducing the possible interaction force between the component 1 and the working device 70, thereby reducing the possible damage to the working device 70 and the component 1 caused by the lifting operation.

[0102] On the other hand, the traction spring 82 can store the traction rope 81 when the component 1 is placed on the working device 70, so that the connection between the component 1 and the working device 70 is as taut as possible, ensuring that the opening of the main body 10 is facing a certain direction and is not easy to shake.

[0103] This application also provides a system 2 for lifting and filling liquids, including a transport mechanism 60, a working device 70, and a component 1 for lifting and filling liquids as described in any of the above embodiments. The transport mechanism 60 is connected to the movable joint 20, and the main body 10 is connected to the working device 70.

[0104] Figure 6 A schematic diagram of a system 2 for hoisting and adding liquids is shown. Figure 6As shown, the transport mechanism 60 refers to the structure used for lifting and / or refilling liquids onto the work device 70. For example, the transport mechanism 60 may include equipment such as drones, robotic arms, and cranes for lifting the work device 70, and may also include structures such as refill tanks and refill pipes for refilling liquids onto the work device 70. The work device 70 refers to equipment used for operations such as cleaning and spraying in the work area.

[0105] The lifting and liquid filling component 1 provided in this application embodiment connects the transport mechanism 60 and the working device 70. Specifically, the movable joint 20 in component 1 is connected to the transport mechanism 60. The transport mechanism 60 transports the movable joint 20 into the hollow structure of the main body 10. By controlling the fixing part 30 to insert into the groove 21 of the movable joint 20, the movable joint 20 is locked with the main body 10. While pulling the movable joint 20, the transport mechanism 60 can drive the main body 10 and the working device 70 connected to the main body 10 to move together, thereby realizing the lifting of the working device 70.

[0106] Meanwhile, the filling channel 22 on the movable joint 20 is connected to the discharge hole 14 on the main body 10. While the transport mechanism 60 is hoisting the working device 70, it can also deliver liquid to the working device 70 through the filling channel 22 and the discharge hole 14.

[0107] The hoisting and liquid filling system 2 provided in this application embodiment can realize the functions of hoisting the working device 70 and filling the working device 70 with liquid in the same structure, which can reduce the complexity of the system 2 and improve work efficiency.

[0108] According to some embodiments of this application, the working device 70 includes a liquid storage tank 71 with a liquid inlet. The system 2 includes a first filling pipe 91, which connects the filling channel 22 of the movable connector 20 and the liquid to be filled; and a second filling pipe 92, which connects the discharge hole 14 of the main body 10 and the liquid inlet of the working device 70.

[0109] like Figure 6 As shown, the working device 70 is usually equipped with a liquid storage tank 71, which carries a certain amount of liquid needed during the operation. The liquid inlet on the liquid storage tank 71 is used to deliver liquid into the liquid storage tank 71.

[0110] Before being hoisted to the work area, the main body 10 can be connected to the work device 70, and the discharge port 14 of the main body 10 and the liquid inlet port of the work device 70 can be connected through the second filling pipe 92. When hoisted to the work area, the work device 70 carries the main body 10 and the second filling pipe 92 to work together in the work area.

[0111] When the liquid in the storage tank 71 is about to run out, the lifting part 23 of the movable joint 20 connects to the transport mechanism 60, and at the same time, the first filling pipe 91 connects the filling channel 22 of the movable joint 20 and the liquid to be filled. The transport mechanism 60 transports the movable joint 20 to above the opening 12 of the main body 10 and controls the movable joint 20 to fall into the hollow structure, and the fixing part 30 locks the movable joint 20 to the main body 10. On the one hand, the liquid to be filled can be transported to the storage tank 71 of the working device 70 through the first filling pipe 91, the filling channel 22, the discharge hole 14 and the liquid inlet of the storage tank 71, realizing the operation of filling the working device 70 with liquid; on the other hand, when the fixing part 30 passes through the through hole 13 and the groove 21, the transport mechanism 60 lifts the component 1, and the component 1 drives the working device 70 to be lifted by the traction rope 81 and the traction spring 82, realizing the lifting operation of the working device 70. The liquid to be added can be stored in the ground device or in the liquid tank of the transport mechanism 60, which will then carry it to the vicinity of component 1 and deliver the liquid to the storage tank 71.

[0112] The first filling pipe 91 and the second filling pipe 92 provide a channel from the liquid to be filled to the liquid storage tank 71 of the working device 70, allowing for timely replenishment when the liquid carried by the working device 70 is about to run out. Furthermore, by reusing the lifting structure for liquid filling, the complexity of system 2 is reduced, and the working device 70 can be replenished with the required liquid without leaving the work area, thus improving the working efficiency of the working device 70.

[0113] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
