Description

Technical Field

[0001] This utility model relates to the field of drone hoisting technology, and in particular to a fusing device for a hoisting line and a drone hoisting and transportation system. Background Technology

[0002] In recent years, the large-scale deployment of photovoltaic power plants has spurred the demand for automated cleaning, making photovoltaic cleaning robots a key piece of equipment for improving power generation efficiency. To adapt to complex scenarios such as mountains, water surfaces, and distributed rooftops, drone-borne transportation solutions have gradually become the mainstream method for deploying and retrieving photovoltaic cleaning robots, using load-bearing ropes to hoist the robots onto or retrieve them from the photovoltaic arrays.

[0003] When flying in complex outdoor environments (such as near forests, high-voltage cables, or building structures), the suspended load-bearing ropes are prone to entanglement with tree branches, cables, or other obstacles, causing both the drone and the photovoltaic cleaning robot to become trapped at high altitudes. Once entanglement occurs, the photovoltaic cleaning robot cannot escape, and the drone, due to continuous hovering and power consumption, eventually runs out of power and crashes, causing equipment damage or even secondary safety accidents.

[0004] Current industry solutions focus on passive defense, relying on drone obstacle avoidance systems to avoid known obstacles, but have low recognition rates for dynamic obstacles (such as swaying branches) and slender objects (cables); in addition, while high-strength lightweight ropes are used to reduce weight, the phenomenon of ropes getting tangled with obstacles cannot be eliminated. Utility Model Content

[0005] The purpose of this utility model is to propose a fusing device for hoisting lines and a drone hoisting and transportation system to solve one of the above-mentioned technical problems.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A fusible link device for a hoisting line, comprising:

[0008] The housing has through holes on its opposite side walls for the hoisting line to pass through;

[0009] The adjacent heating element and the hot melt element are both located inside the housing;

[0010] In the case where the fuse mechanism of the fuse device is not triggered, the heating element and the hoisting line body passing through the through hole maintain a preset distance;

[0011] When the fuse mechanism of the fuse device is triggered, the heating element heats up and melts the hot melt. The melted hot melt releases the heating element and causes it to move to contact the hoisting line, so that the hoisting line is broken.

[0012] As an optional solution for the fusion device of the hoisting line, the fusion device further includes a mounting base, and the heating element is configured as a heating ring, which is installed in the mounting base;

[0013] In the case where the fuse mechanism of the fuse device is not triggered, the hoisting line passes through the heating ring and extends along its axis, and a preset distance is maintained between the hoisting line and the inner wall of the heating ring.

[0014] When the fuse mechanism of the fuse device is triggered, the mounting base is configured to move the heating element to contact the hoisting line.

[0015] As an optional solution for the fusion device of the hoisting line, the mounting base is configured as a heat-conducting element, and the hot melt is sandwiched between the mounting base and the inner wall of the housing.

[0016] As an alternative to the fusion device of the hoisting line, the hot melt abuts against the mounting base in a first direction to restrict the movement of the mounting base in the first direction;

[0017] Along a second direction perpendicular to the first direction, the opposite side walls of the housing abut against the mounting base to restrict the movement of the mounting base in the second direction, both the first and second directions being perpendicular to the centerline of the through hole.

[0018] As an alternative to the fusion device of the hoisting line, the heating element includes a ceramic resistance wire, which is electrically connected to the control panel via two electrodes.

[0019] As an optional solution for the fusion device of the hoisting line, the housing is provided with an oblong hole for the electrode to pass through, and the oblong hole extends along the moving direction of the heating element.

[0020] As an alternative to the fusion device for the hoisting line, the fusion device further includes a driving member located on the side of the heating element away from the hot melt, and the driving member is configured to drive the heating element while the hot melt is melting, so that the heating element comes into contact with the hoisting line.

[0021] As an optional solution for the fusion device of the hoisting line, the driving component includes an elastic element, one end of which is connected to the housing;

[0022] When the fuse-breaking mechanism of the fuse-breaking device is not triggered, the hot melt body forces the heating element to press against the elastic element; when the fuse-breaking mechanism of the fuse-breaking device is triggered, the heating element moves to contact the hoisting line body under the drive of the elastic restoring force of the elastic element.

[0023] As an optional solution for the fusion device of the hoisting line, the melting point of the hot melt is 80℃~100℃.

[0024] As an optional solution for the fusion device of the hoisting line, the preset spacing is 0.5mm to 2mm.

[0025] A drone-based hoisting and transportation system, comprising:

[0026] Transporting drones;

[0027] A winch, installed on the transport drone, is used to retrieve and deploy the hoisting line for suspended loads.

[0028] The fusion device for the hoisting line, as described in any of the above schemes, is located on the winch, and the hoisting line being wound up and down by the winch passes through the fusion device.

[0029] As an optional feature of the drone-based lifting and transportation system, the object being lifted includes a photovoltaic cleaning robot.

[0030] The beneficial effects of this utility model are:

[0031] The present invention provides a fusing device for a hoisting line, comprising a housing and adjacently arranged heating elements and a fusible element, both housed within the housing. When the fusing mechanism is not triggered, the hoisting line passes through a through-hole in the housing to hoist the load, maintaining a preset distance between the heating element and the hoisting line to avoid affecting its deployment, retraction, and normal service life. When the fusing mechanism is triggered, the heating element heats up and melts the fusible element. The molten fusible element releases heat and moves to contact the hoisting line, whereby the heat melts the hoisting line, causing it to detach from the hoisting line, reducing the probability of damage and preventing accidents.

[0032] This utility model provides a drone lifting and transportation system, including a carrier drone, a winch, and a fusion device for the aforementioned lifting line. The winch is installed on the carrier drone and is used to retrieve and deploy the lifting line for the suspended load. The fusion device is located on the winch, and the lifting line retrieved and deployed by the winch passes through the fusion device to connect with the load. Through the active fusion mechanism of the fusion device, the lifting line is immediately triggered to separate when it becomes entangled with an obstacle, allowing the carrier drone to quickly escape and avoid crashing due to battery depletion; at the same time, it ensures that the load is controlled and dropped to a safe area, solving the risk of both the carrier drone and the load being stranded at high altitudes and reducing the occurrence of safety accidents.

[0056] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0057] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0058] like Figures 1-4 As shown, the fusion device for the hoisting line provided in this embodiment is used to promptly fuse the hoisting line 500 and separate the hoisted object in case of an accident requiring the removal of the object. The hoisting line 500 can be a linear body used for hoisting, such as a rope, sling, or strap.

[0059] The fusion device 300 includes a housing 1, an adjacently arranged heating element 2, and a hot melt element 3. Through holes are provided on opposite side walls of the housing 1 for the lifting line 500 to pass through. Both the heating element 2 and the hot melt element 3 are located within the housing 1. When the fusion mechanism of the fusion device 300 is not triggered, the heating element 2 maintains a preset distance from the lifting line 500 passing through the through holes. When the fusion mechanism of the fusion device 300 is triggered, the heating element 2 heats up and melts the hot melt element 3. The melted hot melt element 3 releases the heating element 2 and causes it to move to contact the lifting line 500, thus severing the lifting line 500. During normal lifting operations, the lifting line 500 passes through the through holes on opposite sides of the housing 1, and the heating element 2 remains within the housing 1, maintaining a preset distance from the fusion device 300. This does not affect the raising or lowering of the lifting line 500, nor does it affect its normal service life. When the hoisting line 500 encounters an obstacle and becomes entangled, the fusion device 300 activates the fusion mechanism. The heating element 2 heats up and melts the hot melt element 3. After the hot melt element 3 melts, the heating element 2 moves to contact the hoisting line 500, melting the hoisting line 500 and separating the hoisted object from the hoisting line 500, reducing the probability of damage to the hoisted object and avoiding the occurrence of safety accidents.

[0060] In one embodiment, the preset spacing is 0.5mm to 2mm. Within this preset spacing, the raising and lowering of the hoisting line 500 is not affected, and the heating element 2 can be quickly moved to contact the hoisting line 500 after the hot melt 3 melts.

[0061] For example, the preset spacing includes, but is not limited to, 1mm, 1.5mm, etc.

[0062] In one embodiment, the melting point of the lifting line 500 is 100°C to 700°C. The lifting line 500 can be a rope woven from ultra-high molecular weight polyethylene fiber braided yarn or a metal sling. Heating elements 2 with different heating capacities are provided for different materials of the lifting line 500 to ensure that the lifting line 500 can be melted within a short time.

[0063] For example, when the hoisting line 500 is a rope woven from ultra-high molecular weight polyethylene fiber braided yarn, the melting point is 140℃~160℃, that is, the rope woven from ultra-high molecular weight polyethylene fiber braided yarn begins to melt at 140℃ or 145℃.

[0064] In one embodiment, the melting point of the hot melt 3 is 80°C to 100°C. The melting point of the hot melt 3 is lower than that of the hoisting line 500, so as to ensure that the heating element 2 can quickly melt the hot melt 3 after heating, so that the heating element 2 can quickly come into contact with the hoisting line 500, melt the hoisting line 500 at high temperature, and accelerate the response of the fuse mechanism.

[0065] The hot melt 3 is a hot melt ring or hot melt block made of plastic or rubber. For example, the hot melt 3 is made of polyvinyl chloride, which begins to melt at 80°C or 85°C.

[0066] Specifically, the housing 1 includes a bottom shell 11 and a top cover 12. The bottom shell 11 includes a base plate and four side plates surrounding the base plate. The heating element 2 and the hot melt element 3 enter the housing 1 through an opening at the top of the bottom shell 11. The bottom shell 11 and the top cover 12 have through holes facing each other. The through hole on the bottom shell 11 is a first through hole 111, and the through hole on the top cover 12 is a second through hole 121. The hoisting line 500 passes through the second through hole 121 and the first through hole 111 in sequence and then connects to the object being hoisted. The top cover 12 and the bottom shell 11 are detachably connected by fastening screws or snap-fit ​​mechanisms, facilitating assembly and maintenance.

[0067] In one embodiment, such as Figure 5 , Figure 6 and Figure 10 As shown, the heating element 2 includes a ceramic resistance wire 21, which is electrically connected to the control panel via two electrodes 22. The ceramic resistance wire 21 has high temperature resistance and oxidation resistance properties, achieving precise electrothermal conversion in the fuse device 300. Through the direct connection of the electrodes 22 to the control panel, it achieves millisecond-level trigger response, ensuring that the hoisting cable 500 melts quickly during winding.

[0068] Specifically, the two electrodes 22 are a positive electrode and a negative electrode, respectively, and the positive electrode and the negative electrode are connected to the control panel to form a conductive circuit.

[0069] For example, the two electrodes 22 are electrically connected to the control panel of the transport drone 100, and the control panel of the transport drone 100 is communicatively connected to the remote controller. The fuse device 300 can be controlled by operating the remote controller. The communication connection between the control panel of the transport drone 100 and the remote controller, as well as the electrical connection between the electrodes 22 and the control panel, can be designed with reference to existing technology. This is not the focus of improvement in this embodiment and will not be described in detail here.

[0070] Of course, in other embodiments, the heating element 2 may also be a semiconductor thin film heater or a chemical energy release module, etc.; the two electrodes 22 may also be electrically connected to the control panel of the winch 200.

[0071] In one embodiment, the housing 1 is provided with an oblong hole 122 through which the electrode 22 passes. The oblong hole 122 extends along the moving direction of the heating element 2, so that when the heating element 2 moves freely with the melting process of the hot melt 3 after the fuse mechanism of the fuse device 300 is triggered, the electrode 22 always moves along the extending direction of the oblong hole 122 to maintain electrical connection with the control panel, dynamically ensuring continuous power supply and heating during the fuse cycle, and avoiding the failure of the fuse due to the electrode 22 detaching from the electrical connection.

[0072] Specifically, an oblong hole 122 is provided on the upper cover 12. Two oblong holes 122 are provided on each side of the second through hole 121. The distance between the two oblong holes 122 is the same as the distance between the two electrodes 22. The two electrodes 22 of the heating element 2 pass through the two oblong holes 122 corresponding to their positions and are electrically connected to the control panel. At the same time, regardless of the orientation of the electrodes 22, the heating element 2 can achieve zero-deviation alignment and insertion between the electrodes 22 and the oblong holes 122.

[0073] In one embodiment, such as Figures 6-9 As shown, the fuse 300 also includes a mounting base 5, and the heating element 2 is configured as a heating ring, which is installed inside the mounting base 5. In the state where the fuse mechanism of the fuse 300 is not triggered, the lifting line 500 passes through the heating ring and extends along its axis, maintaining a preset distance between the lifting line 500 and the inner wall of the heating ring. In the state where the fuse mechanism of the fuse 300 is triggered, the mounting base 5 is configured to move the heating element 2 to contact the lifting line 500. The heating element 2 is configured as a heating ring, and the lifting line 500 passes through the hollow cavity of the heating ring. The heating ring is supported by the mounting base 5, maintaining a preset distance between its inner wall and the lifting line 500 when the fuse mechanism of the fuse 300 is not triggered; and moving with the mounting base 5 to contact the lifting line 500 after the fuse mechanism of the fuse 300 is triggered.

[0074] Specifically, the mounting base 5 includes a base 51 and a cover plate 52. The base 51 has a limiting hole 511 extending through its upper and lower ends, and the heating ring is disposed within the limiting hole 511. The limiting hole 511 is a stepped hole, with its larger diameter section matching the outer diameter of the heating ring and its smaller diameter section matching the inner diameter of the hollow cavity of the heating ring. The smaller diameter section is positioned away from the cover plate 52. The cover plate 52 has a third through hole 522 for the hoisting line 500 to pass through. The heating ring is placed within the larger diameter section of the stepped hole, and then the cover plate 52 is fixed to the base 51 using fastening screws or snap-fit ​​mechanisms.

[0075] Furthermore, to ensure the smooth passage of the two electrodes 22, two limiting grooves 521 are provided on each of the opposite sides of the cover plate 52. Similarly, the spacing between the two limiting grooves 521 is adapted to the spacing between the two electrodes 22. The limiting grooves 521 are also configured as strip-shaped grooves extending along the moving direction of the heating element 2, and one end of the strip-shaped groove passes through the end of the cover plate 52, which facilitates processing.

[0076] Of course, in other embodiments, the heating element 2 can also be configured as a block or other structure; or, the heating element 2 can be configured as a plurality of sub-heating elements that are circumferentially distributed around the hoisting line 500; correspondingly, the hot melt body 3 includes a plurality of sub-hot melt bodies that correspond one-to-one with the sub-heating elements. With this configuration, after the plurality of sub-hot melt bodies melt, the plurality of sub-heating elements move toward the hoisting line 500 and come into contact with the hoisting line 500, thereby melting the hoisting line 500.

[0077] In one embodiment, the mounting base 5 is configured as a heat-conducting element, and the hot melt 3 is sandwiched between the mounting base 5 and the inner wall of the housing 1. The hot melt 3 is located on the outside of the mounting base 5, and the heating element 2 is located inside the mounting base 5. To ensure that the heat from the heating element 2 is quickly transferred to the hot melt 3 to melt the hot melt 3, the mounting base 5 is configured as a heat-conducting element.

[0078] Of course, in other embodiments, the hot melt 3 can also be disposed between the hoisting line 500 and the heating element 2.

[0079] For example, the mounting base 5 is made of a material with high thermal conductivity, such as copper.

[0080] Specifically, the hot melt 3 is configured as a hot melt block, and the hot melt block is configured as a porous mesh structure. The hot melt block adopts a porous mesh topology, and its lattice ribs form a three-dimensional mechanical framework in the solid state, providing impact-resistant support for the heating element 2 and the mounting base 5. After the melt is triggered, the mesh units synchronously store heat to generate a capillary melting effect, which shortens the total phase change time. This structure achieves a dynamic balance between solid strength and liquid fluidity by controlling the pore wall thickness and porosity, achieving a dual gain between support stability and melt responsiveness.

[0081] In one embodiment, the heat-fused body 3 abuts against the mounting base 5 along a first direction to restrict the movement of the mounting base 5 in the first direction. Along a second direction perpendicular to the first direction, opposite side walls of the housing 1 abut against the mounting base 5 to restrict the movement of the mounting base 5 in the second direction. Both the first and second directions are perpendicular to the centerline of the through hole. This arrangement allows the mounting base 5 to stably support the heating element 2 before the fuse is triggered, and after the fuse is triggered, it can only move along the first direction to quickly contact the lifting line 500.

[0082] It should be noted that in this embodiment, the first direction is the length direction of the housing 1, the second direction is the width direction of the housing 1, and the center line of the through hole extends along the height direction of the housing 1.

[0083] Specifically, two flanges 513 are provided at intervals on the outer walls of opposite sides of the base 51 along the second direction and on the bottom of the base 51, and the flanges 513 abut against the inner wall of the housing 1; or a sliding groove adapted to the flanges 513 is provided on the inner wall of the housing 1, and the flanges 513 slide in the sliding groove.

[0084] In one embodiment, the fuse 300 further includes a driving member located on the side of the heating element 2 away from the molten metal 3. The driving member is configured to drive the heating element 2 while the molten metal 3 is melting, so that the heating element 2 comes into contact with the lifting line 500. By providing the driving member, when the fuse mechanism is triggered, during the melting process of the molten metal 3, the driving member drives the heating element 2 to move, providing driving force for the movement of the heating element 2, thereby achieving a rapid response of the fuse mechanism.

[0085] In one embodiment, the driving component includes an elastic element 41, one end of which is connected to the housing 1. When the melting mechanism of the melting device 300 is not triggered, the hot melt 3 forces the heating element 2 to press against the elastic element 41, thus compressing the elastic element 41. After the melting mechanism of the melting device 300 is triggered, the heating element 2 moves to contact the hoisting line 500 under the drive of the elastic restoring force of the elastic element 41. The elastic element 41 has a pre-compression energy storage mechanism under the constraint of the solid hot melt 3, which ensures that the heating element 2 is locked with zero displacement under normal conditions, and can also release elastic potential energy at the moment of phase change of the hot melt 3, driving the heating element 2 to accurately contact the hoisting line 500, realizing the synchronization of molten state change and mechanical triggering.

[0086] Specifically, the elastic element 41 is a spring, which is located on the side of the mounting base 5 away from the hot melt 3. The base 51 is provided with a limiting protrusion, and a limiting cavity 512 is provided in the limiting protrusion. One end of the spring is placed in the limiting cavity 512. The side wall of the housing 1 is connected to a limiting screw 42. The limiting screw 42 is screwed to the bottom housing 11 from the outside. The limiting head of the limiting screw 42 is located outside the bottom housing 11, and the limiting post of the limiting screw 42 extends into the bottom housing 11. The other end of the spring is sleeved on the limiting post to provide guidance for the extension and contraction of the spring, ensuring that the heating element 2 and the hoisting line 500 make precise contact under the action of the elastic restoring force of the spring.

[0087] Of course, in other embodiments, the driving element may also be other linear driving elements such as electric actuators or cylinders.

[0088] like Figure 10 and Figure 11As shown, this embodiment also provides a drone lifting and transportation system, including a carrier drone 100, a winch 200, and a fusion device for the aforementioned lifting line 500. The winch 200 is installed on the carrier drone 100 and is used to retrieve and deploy the lifting line 500 for suspending the load. The fusion device for the lifting line is located on the winch 200, and the lifting line 500 retrieved and deployed by the winch 200 passes through the fusion device 300 and connects to the load. Through the active fusion mechanism of the fusion device 300, the lifting line 500 is immediately triggered to separate when it becomes entangled with an obstacle, allowing the carrier drone 100 to quickly escape and avoid running out of power and crashing; at the same time, it ensures that the load is controlled to fall to a safe area, solving the risk of both the carrier drone 100 and the load being stranded at high altitude, and reducing the occurrence of safety accidents.

[0089] The specific structure of the winch 200 can be designed with reference to existing technology. The fuse device 300 is installed on the wire puller 202 of the winch 200 through the fixing frame 201. The structural design of the fixing frame 201 allows the hoisting wire 500 that is wound up and down by the winch 200 to pass through the second through hole 121, the third through hole 522, the hollow cavity of the heating ring and the first through hole 111 of the housing 1 in sequence.

[0090] In one embodiment, the object being lifted includes a photovoltaic cleaning robot 400. In this embodiment, the drone-borne lifting and transportation system cleans the photovoltaic array by suspending the photovoltaic cleaning robot 400, thereby improving the power generation efficiency of the photovoltaic cleaning robot 400.

[0091] Specifically, in order to ensure the stability of the photovoltaic cleaning robot 400 during operation, the drone hoisting and transportation system also includes a grabbing drone 600. The hoisting line 500 is connected to the grabbing drone 600. The grabbing drone 600 has a grabbing part for grabbing the photovoltaic cleaning robot 400, and the grabbing part can be set as a grabbing robotic arm.

[0092] Of course, the objects that can be lifted by the drone lifting and transportation system provided in this embodiment are not limited to the photovoltaic cleaning robot 400, but can also be other products that require high-altitude lifting to achieve their functions.

[0093] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
