Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0054] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the structures and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0055] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, step, or component, but does not exclude the presence or addition of one or more other features, elements, steps, or components.

[0056] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0057] In the following description, embodiments of the present application will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0058] like Figures 1 to 12 As shown, one aspect of this application provides an umbrella drying system, including an umbrella drying module comprising a traction rope, an umbrella drying device 200, a winch 100, and a fixed pulley assembly.

[0059] The fixed pulley assembly is positioned above the umbrella drying device 200 and the winch 100. The traction rope cooperates with the fixed pulley assembly and is connected to both the umbrella drying device 200 and the winch 100.

[0060] The winch 100 is used to drive the umbrella drying device 200 to rise relative to the fixed pulley group via the traction rope, and the winch 100 is also used to drive the umbrella drying device 200 to fall relative to the fixed pulley group via the traction rope.

[0061] The umbrella drying system provided in this application involves hanging the parachute to be dried on the drying unit, starting the winch 100, which pulls the steel wire rope to raise the drying device. Once the drying device reaches the preset height, the winch 100 is turned off to achieve the purpose of drying the parachute.

[0062] The umbrella drying system provided in this application includes multiple umbrella drying modules. The number of umbrella drying modules can be 2-5, such as 2, 3, 4 or 5, and preferably, the number of umbrella drying modules is 4.

[0063] like Figures 1 to 3 As shown, the umbrella drying device 200 includes a crossbeam 220 and an umbrella drying unit 210. The umbrella drying unit 210 includes a drive component 211, a transmission assembly, and an umbrella drying rack 218. The crossbeam 220 is preferably positioned above the ground. The transmission assembly includes a first swing rod 214, one end of which is pivotally connected to the crossbeam 220, and the other end of which is pivotally connected to the umbrella drying rack 218. The drive component 211 is mounted on the crossbeam 220 and connected to the first swing rod 214, so that the drive component 211 drives the first swing rod 214, thereby causing the umbrella drying rack 218 to swing relative to the crossbeam 220.

[0064] In this embodiment, the swinging of the umbrella rack 218 relative to the crossbeam 220 means that the umbrella rack 218 can move back and forth relative to the crossbeam 220 between two positions; the ground can be an outdoor ground or an indoor ground.

[0065] The umbrella drying device 200 provided in this application, when in use, places the parachute on the umbrella drying frame 218, so that the parachute moves with the umbrella drying frame 218. The drive component 211 is activated, so that the drive component 211 drives the first swing rod 214, which in turn causes the umbrella drying frame 218 to swing relative to the crossbeam 220. Since the parachute on the umbrella drying frame 218 swings together with the umbrella drying frame 218, on the one hand, water droplets are more likely to drip off the parachute during the swing process, and on the other hand, it also increases the intensity of the interaction between the parachute and the surrounding air and increases the airflow velocity around the parachute, so that the parachute can dry faster, thereby shortening the drying time required for the parachute and improving the drying efficiency of the parachute.

[0066] Optionally, the drive unit 211 is installed on the top of the crossbeam 220, the umbrella rack 218 is located below the crossbeam 220, the top end of the first swing rod 214 is pivotally connected to the crossbeam 220, and the bottom end of the first swing rod 214 is pivotally connected to the umbrella rack 218, so that the plane of the swing trajectory of the first swing rod 214 is parallel to the length direction of the crossbeam 220. The driving component 211 is generally fixed to the crossbeam 220 via a connector. By mounting the driving component 211 on top of the crossbeam 220 and supporting it, the weight of the driving component 211 is less likely to act on the connector, reducing the risk of connector failure and improving the reliability of the umbrella drying device 200. Positioning the umbrella rack 218 below the crossbeam 220 prevents obstruction from other structures on the umbrella drying device 200 when taking or placing the parachute, facilitating the placement and removal of the parachute. Furthermore, ensuring the plane of the swing trajectory of the first swing rod 214 is parallel to the length of the crossbeam 220 reduces the likelihood of the first swing rod 214 colliding with the crossbeam 220 during swing. This allows the first swing rod 214 to be positioned anywhere along the length of the crossbeam 220, increasing the flexibility of the umbrella drying unit 210's arrangement on the crossbeam 220 and making the umbrella drying device 200 suitable for more indoor or outdoor drying areas. Of course, the drive unit 211 can also be positioned below the crossbeam 220, the umbrella rack 218 can be positioned on the side of the crossbeam 220, and / or the first swing rod 214 can be swung in a direction perpendicular to the crossbeam 220.

[0067] Optionally, the transmission assembly further includes a first connecting rod 212 and a second connecting rod 213. One end of the first connecting rod 212 is fixed to the rotating rod of the driving member 211. The driving member 211 is used to drive the first connecting rod 212 to pivot. The first connecting rod 212 is perpendicular to the rotating rod. The other end of the first connecting rod 212 is pivotally connected to one end of the second connecting rod 213, and the other end of the second connecting rod 213 is pivotally connected to the first swing rod 214. When the driving member 211 is activated, the rotating rod of the driving member 211 rotates. Since the first connecting rod 212 is fixedly connected to the rotating rod, the first connecting rod 212 rotates together with the rotating rod. The end of the second connecting rod 213 connected to the first connecting rod 212 rotates together with the first connecting rod 212. During this process, the end of the second connecting rod 213 connected to the umbrella rack 218 drives the umbrella rack 218 to swing. In this way, the rotation of the rotating rod of the driving member 211 can drive the umbrella rack 218 to swing continuously. Of course, the driving component 211 can also be a linear driving component, with the rotating rod of the linear driving component perpendicular to the first swing rod 214, and the rotating rod of the linear driving component pivotally connected to the first swing rod 214. The rotating rod of the linear driving component moves back and forth, driving the first swing rod 214, and then driving the umbrella rack 218 to swing.

[0068] Optionally, the transmission assembly includes two first swing rods 214, located on opposite sides of the crossbeam 220. That is, both first swing rods 214 are pivotally connected to the crossbeam 220 and to the umbrella rack 218. The two first swing rods 214 act as a single unit to drive the umbrella rack 218 to swing, improving the stability of the umbrella rack 218's swing. In this embodiment, the second connecting rod 213 may be pivotally connected to one of the two first swing rods 214, or the second connecting rod 213 may be pivotally connected to both first swing rods 214.

[0069] Optionally, the transmission assembly further includes two second swing rods 217, each arranged parallel to the first swing rod 214. One second swing rod 217 and one first swing rod 214 are located on one side of the crossbeam 220, and the other second swing rod 217 and the other first swing rod 214 are located on the other side of the crossbeam 220. The first swing rod 214 and the second swing rod 217 located on the same side of the crossbeam 220 are arranged in the length direction of the crossbeam 220. The top end of the second swing rod 217 is pivotally connected to the crossbeam 220, and the bottom end of the second swing rod 217 is pivotally connected to the umbrella rack 218. In other words, the second swing rod 217 swings together with the first swing rod 214 and the umbrella rack 218. Since the second swing rod 217 is set parallel to the first swing rod 214, the second swing rod 217 plays a certain guiding role in the swing of the umbrella rack 218 during the swing process. The two second swing rods 217 jointly guide the swing of the umbrella rack 218, and together with the two first swing rods 214 drive the umbrella rack 218, further improving the stability of the swing of the umbrella rack 218.

[0070] Optionally, the transmission assembly further includes a first connecting shaft, a second connecting shaft, a first bearing, a second bearing, a first bearing seat 215, and a second bearing seat 216. Both the first bearing seat 215 and the second bearing seat 216 are fixed to the top of the crossbeam 220. The first bearing is mounted on the first bearing seat 215, and the first connecting shaft is mounted on the first bearing. The two ends of the first connecting shaft are connected to the tops of the two first swing rods 214, respectively. The second bearing is mounted on the second bearing seat 216, and the second connecting shaft is mounted on the second bearing. The two ends of the second connecting shaft are connected to the tops of the two second swing rods 217, respectively. This eliminates the need to drill holes in the crossbeam 220 to install the pivot shaft connected to the first connecting rod 212 or the pivot shaft connected to the second connecting rod 213. In other words, the crossbeam 220's structure is not damaged during the installation of the transmission assembly and the umbrella rack 218, thus ensuring the crossbeam 220 has good strength and maintains a certain level of reliability. In this embodiment of the application, the bottom end of the first swing rod 214 can be connected to the umbrella rack 218 via a shaft, bearing and bearing seat, and the bottom end of the second swing rod 217 can also be connected to the umbrella rack 218 via a shaft, bearing and bearing seat.

[0071] Optionally, the umbrella rack 218 includes a main hanging member 218d and a mounting base 218e. The main hanging member 218d is installed at the bottom of the mounting base 218e, and the top of the mounting base 218e is connected to the first swing rod 214. The main hanging member 218d can be used to suspend the top of a round umbrella, and the parachute rope can also be hung on the main hanging member 218d. When the parachute is hung vertically upright, the parachute rope is hung at the main hanging member 218d; when the parachute is hung vertically upside down, the parachute pack and parachute rope are knotted and hung at the main hanging member 218d. In this embodiment, the main hanging member 218d is preferably a hook, but it can also be a hanging ring or a clip. When this embodiment also includes a second swing rod 217, the mounting base 218e is also connected to the second swing rod 217.

[0072] Optionally, the umbrella rack 218 further includes a connecting rod 218c, an umbrella ring 218a, and multiple auxiliary hanging components 218b. The mounting base 218e is connected to the umbrella ring 218a via the connecting rod 218c. The position of the mounting base 218e corresponds to the center position of the umbrella ring 218a, and the umbrella ring 218a is located below the mounting base 218e. The auxiliary hanging components 218b are evenly distributed on the umbrella ring 218a. When the parachute is hung vertically upside down, each auxiliary hanging component 218b can hang two sets of parachute lines on the edge of the parachute. It can be understood that the umbrella ring 218a is a ring-shaped component, and the umbrella ring 218a refers to the distribution of multiple parachutes at different positions on the ring-shaped component. In this embodiment, the auxiliary hanging component 218b is preferably a hook, but it can also be a hanging ring or a clip. Preferably, the umbrella rack 218 includes a plurality of connecting rods 218c. In this embodiment, "a plurality" means at least two, and the number of auxiliary hanging components 218b can be 5-20, for example, 5, 10, 15 or 20, etc. The number of auxiliary hanging components 218b is preferably 15.

[0073] Optionally, the umbrella drying unit 210 further includes a wing umbrella drying crossbar 219 and multiple umbrella clips installed on the wing umbrella drying crossbar 219. Each of the umbrella clips is distributed along the length of the wing umbrella drying crossbar 219. The wing umbrella drying crossbar 219 is horizontally positioned and detachably mounted on the umbrella ring 218a. The wing umbrella drying crossbar 219 is used to hang wing umbrellas or connect umbrellas; it can be detached when not in use. The multiple umbrella clips on the wing umbrella drying crossbar 219 are used to clamp the edges of the wing umbrellas.

[0074] Optionally, the umbrella drying device 200 provided in this application embodiment includes multiple umbrella drying units 210, each of which is evenly distributed on the crossbeam 220. This increases the number of parachutes that can be dried, further improving drying efficiency. When the umbrella drying unit 210 provided in this application embodiment includes a wing umbrella drying crossbar 219, the wing umbrella drying crossbar 219 can be parallel to the crossbeam 220 and positioned on multiple umbrella rings 218a. In this application embodiment, multiple crossbeams 220 can also be provided, with multiple umbrella drying units 210 provided on each crossbeam 220.

[0075] like Figures 4 to 12 As shown, the winch 100 includes a frame 1b0, and a roller 110, a rotation drive 180, and a power switching device, all mounted on the frame 1b0. The roller 110, the power switching device, and the rotation drive 180 are sequentially connected in a transmission manner, and the roller 110 is connected to the traction rope.

[0076] The power switching device includes a first base 160 and a first roller mounting gear 1a0, as well as a manual drive assembly 130, a drive shaft 190, a connecting assembly 150, and an operating handle 140, all mounted on the first base 160. The drive shaft 190 is rotatably engaged with the first base 160, the first roller mounting gear 1a0 is rotatably engaged with the drive shaft 190, the manual drive assembly 130 is drive-driven with the first roller mounting gear 1a0, and the connecting assembly 150 is connected to both the operating handle 140 and the drive shaft 190.

[0077] The operating handle 140 is used to drive the connecting assembly 150 to connect the connecting assembly 150 with the first roller mounting gear 1a0, thereby enabling the drive shaft 190 to engage with the first roller mounting gear 1a0. The operating handle 140 is also used to drive the connecting assembly 150 to separate the connecting assembly 150 from the first roller mounting gear 1a0, thereby enabling the first roller mounting gear 1a0 to rotate relative to the drive shaft 190.

[0078] In this embodiment of the application, the separation of the connecting component 150 from the first roller mounting gear 1a0 means that the connecting component 150 and the first roller mounting gear 1a0 are not in direct contact; the rotational engagement between the drive shaft 190 and the first base 160, and between the first roller mounting gear 1a0 and the drive shaft 190, is achieved through bearings.

[0079] The power switching device provided in this application embodiment is used in a winch 100. The winch 100's roller 110 is mounted on the power switching device, so that the roller 110 is coaxially and fixedly connected to the first roller mounting gear 1a0. A traction rope (preferably a steel wire rope) for pulling a parachute is wound around the roller 110. The drive shaft 190 is connected to a motor (preferably a motor for rotation drive 180). When it is necessary to drive the roller 110 to rotate via the motor, the operating handle 140 is manipulated to drive the connecting assembly 150 to make the connecting assembly... 150 is connected to the first roller mounting gear 1a0, thereby enabling the drive shaft 190 to engage with the first roller mounting gear 1a0. The motor drives the drive shaft 190, which in turn drives the roller 110 to rotate. When it is necessary to manually drive the roller 110 to rotate, the operating handle 140 is used to drive the connecting component 150, so that the connecting component 150 is separated from the first roller mounting gear 1a0, thereby enabling the first roller mounting gear 1a0 to rotate relative to the drive shaft 190. The first roller mounting gear 1a0 is driven by the manual drive component 130.

[0080] When the power switching device provided in this application is applied to the winch 100, the roller 110 of the winch 100 can be driven by a rotary drive component 180 connected to the drive shaft 190, or it can be manually driven by a manual drive component 130. This allows the winch 100 to switch between electric drive and manual drive, thereby enabling the winch 100 to continue parachute drying operations manually even in the event of a power outage. The rotary drive component 180 is preferably an electric motor.

[0081] Optionally, the power switching device provided in this application embodiment further includes the connecting assembly 150, which includes a transmission gear 155 and an internal gear 151. The transmission gear 155 is fixed to the drive shaft 190. Both the first roller mounting gear 1a0 and the transmission gear 155 are used to drive the internal gear 151 in a transmission engagement. The operating handle 140 is used to drive the internal gear 151 to slide in a axial direction on the drive shaft 190, engaging both the first roller mounting gear 1a0 and the transmission gear 155. When it is necessary for the drive shaft 190 to drive the first roller mounting gear 1a0, the operating handle 140 is manipulated to move the internal gear 151 toward the first roller mounting gear 1a0, and the internal gear 151 simultaneously engages with both the first roller mounting gear 1a0 and the transmission gear 155. When it is necessary for the first roller mounting gear 1a0 to rotate relative to the drive shaft 190, the operating handle 140 is manipulated to slide the internal gear 151 toward the transmission gear 155 until the internal gear 151 disengages from the first roller mounting gear 1a0. Of course, holes can also be made in the transmission gear 155 and the first roller mounting gear 1a0, and the connecting assembly 150 can include a connecting rod driven by the operating handle 140. The transmission gear 155 and the first roller mounting gear 1a0 can be connected through the holes in the transmission gear 155 and the first roller mounting gear 1a0, so that the transmission gear 155 can drive the first roller mounting gear 1a0. Alternatively, it can be separated from the first roller mounting gear 1a0 and / or the transmission gear 155, so that the first roller mounting gear 1a0 can rotate relative to the transmission gear 155 and the drive shaft 190.

[0082] Optionally, such as Figure 7 As shown, a groove 151a is formed on the outer wall of the internal gear 151, extending circumferentially. The connecting assembly 150 also includes a toggle member that engages with the groove 151a. The operating handle 140 is used to drive the toggle member, thereby driving the internal gear 151. When the operating handle 140 drives the toggle member, the engagement of the toggle member with the groove 151a on the internal gear 151 allows the toggle member to move the internal gear 151. Alternatively, the toggle member can be a groove, with a portion of the internal gear 151 located within it; the operating handle 140 can then drive the groove to move the internal gear 151.

[0083] Optionally, the connecting assembly 150 further includes a connecting shaft 154 arranged parallel to the drive shaft 190, the actuating element is a toggle bearing 152 that rotatably engages with the connecting shaft 154, the toggle bearing 152 engages with the groove 151a, and the toggle bearing 152 is used to abut against the side wall of the groove 151a, and the operating handle 140 is used to drive the connecting shaft 154 and thus drive the toggle bearing 152. When the operating handle 140 drives the connecting shaft 154, which in turn drives the actuating bearing 152, the actuating bearing 152 abuts against the side wall of the groove 151a, thereby driving the internal gear 151 to move. Since the actuating element uses the actuating bearing 152 and the groove 151a extends circumferentially over the internal gear 151, the actuating bearing 152 will not interfere with the rotation of the internal gear 151 when it engages with the groove 151a, allowing the power transmission between the transmission gear 155, the internal gear 151, and the first roller mounting gear 1a0 to proceed smoothly. Of course, an actuating block can also be used instead of the actuating bearing 152. When the actuating block engages with the groove 151a, there are gaps between the actuating block and the side wall and bottom wall of the groove 151a to avoid interfering with the rotation of the internal gear 151. When the internal gear 151 needs to be actuated, the actuating block abuts against the side wall of the groove 151a, thereby driving the internal gear 151 to move.

[0084] Optionally, the connecting assembly 150 includes a plurality of connecting shafts 154 and a plurality of actuating bearings 152. Each connecting shaft 154 is evenly distributed circumferentially on the internal gear 151, and each actuating bearing 152 corresponds to one connecting shaft 154. That is, the plurality of actuating bearings 152 jointly actuate the internal gear 151, enabling the internal gear 151 to move smoothly and reliably in the axial direction of the drive shaft 190, thereby facilitating smoother switching of the winch 100's power between electric and manual operation. In this embodiment, the "plural" refers to at least two shafts, and the number of connecting shafts 154 and actuating bearings 152 can both be 2-6, such as 2, 3, 4, 5, or 6. Preferably, the number of connecting shafts 154 and actuating bearings 152 is 4.

[0085] Optionally, the connecting assembly 150 further includes a slider 156 and a guide shaft 153. The guide shaft 153 is arranged parallel to the drive shaft 190. One end of the guide shaft 153 is fixed to the first base 160. The slider 156 is fitted onto the guide shaft 153, and the slider 156 and the guide shaft 153 slide in axial direction on the drive shaft 190. Each of the connecting shafts 154 is fixed to the slider 156. The operating handle 140 is used to drive the slider 156 to move along the guide shaft 153. If the internal gear 151 deflects during movement, a large frictional force is easily generated between the internal gear 151 and the first roller mounting gear 1a0 and the transmission gear 155, which hinders the movement of the internal gear 151. In this embodiment, each guide shaft 153 is mounted on the sliding member 156, which allows each guide shaft 153 and each actuating member to move together with the sliding member 156, so that the movement of each actuating member has better synchronicity and consistency, thereby enabling the internal gear 151 to move relatively smoothly relative to the first roller mounting gear 1a0 and the transmission gear 155. Preferably, a through groove is formed on the sliding member 156 to avoid the drive shaft 190. Of course, the operating handle 140 can also drive each actuating member to move separately; or the guide shaft 153 can be mounted on the sliding member 156, and a hole is opened in the first base 160 so that the guide shaft 153 slides into the hole.

[0086] Optionally, the connecting assembly 150 includes multiple guide shafts 153, and the sliding member 156 is a plate arranged axially perpendicular to the drive shaft 190. Multiple through holes are formed on the sliding member 156, each through hole corresponding to and slidingly engaging with each guide shaft 153. Thus, under the guidance of the multiple guide shafts 153, the sliding member 156 is less prone to deflection during movement, thereby preventing the internal gears 151 actuated by the actuating bearings 152 from deflecting during movement, further enabling the internal gears 151 to move more smoothly relative to the first roller mounting gear 1a0 and the transmission gear 155. In this embodiment, the number of through holes on both the guide shafts 153 and the sliding member 156 is preferably two.

[0087] Optionally, the connecting assembly 150 further includes a toggle shaft 157 and a toggle fork 158. The toggle shaft 157 is rotatably engaged with the first base 160. The toggle fork 158 includes a first toggle part 158b, a second toggle part 158d, and a connecting part 158a. The first toggle part 158b, the connecting part 158a, and the second toggle part 158d are sequentially connected to form a U-shaped structure. The connecting part 158a is fixedly connected to the toggle shaft 157. The sliding member 156 is located between the first toggle part 158b and the second toggle part 158d in the axial direction of the drive shaft 190. The toggle shaft 157 is fixedly connected to the operating handle 140. Thus, rotating the operating handle 140 allows the toggle shaft 157 and the toggle fork 158 to rotate, thereby sequentially driving the sliding member 156, the connecting shaft 154, the toggle part, and the internal gear 151 to move in the axial direction of the drive shaft 190. In this embodiment, the actuating shaft 157 can be located either inside or outside the U-shaped structure.

[0088] Optionally, the actuating fork 158 further includes an actuating protrusion 158c, which protrudes from the side of the first actuating portion 158b facing the second actuating portion 158d and abuts against the sliding member 156. When the operating handle 140 drives the actuating fork 158 to move the sliding member 156 closer to the second actuating portion 158d, the actuating protrusion 158c abuts against the sliding member 156, causing the sliding member 156 to move. In this embodiment, preferably, a drive shaft 190 clearance slot for cooperating with the drive shaft 190 is formed on both the first actuating portion 158b and the second actuating portion 158d. Of course, the actuating protrusion 158c can also be provided on the second actuating portion 158d.

[0089] Optionally, the power switching device provided in this application embodiment further includes a locking component 170, which includes a locking ring 171 and a locking pin 172. The locking ring 171 is fitted and fixed to the actuating shaft 157. A locking hole is formed on the outer surface of the locking ring 171. A pin hole extending axially from the drive shaft 190 is formed on the first base 160. The locking pin 172 is slidably engaged with the pin hole. The locking pin 172 is used to engage with the locking hole so that the internal gear 151 engages with both the first roller mounting gear 1a0 and the transmission gear 155. During operation, the operating handle 140 drives the actuating shaft 157 to rotate, which in turn drives the internal gear 151 to move axially along the drive shaft 190 until the internal gear 151 engages with both the first roller mounting gear 1a0 and the transmission gear 155. The locking pin 172 is then operated to engage with the locking hole, preventing the actuating shaft 157 from rotating. The internal gear 151 remains engaged with both the first roller mounting gear 1a0 and the transmission gear 155. When the operating handle 140 needs to be operated again to rotate the actuating shaft 157, the locking pin 172 can be pulled out of the locking hole. This ensures that when the roller 110 of the winch 100 is driven by the rotating drive component 180, the internal gear 151 is less likely to separate from the first roller mounting gear 1a0, improving the safety and reliability of the winch 100.

[0090] Optionally, the locking assembly 170 further includes a pin cap 174, a pin seat 173, and a tension spring. The pin seat 173 is installed in the pin hole, the pin cap 174 is fixed to one end of the locking pin 172, and the pin seat 173 is fitted onto the other end of the locking pin 172. A groove is formed on the end of the pin seat 173 near the pin cap 174, and a locking pin 174a is formed on the end of the pin cap 174 near the pin seat 173. The locking pin 174a is used to cooperate with the groove, and the end of the pin seat 173 near the pin cap 174 is used to abut against the locking pin 174a. One end of the tension spring is connected to the pin cap 174, and the other end of the tension spring is connected to the pin seat 173. Thus, when the locking pin 172 engages with the locking hole, the retaining pin 174a on the pin cap 174 engages with the retaining groove on the pin seat 173. When the locking pin 172 needs to be separated from the locking hole, the tension of the spring is overcome, and the pin cap 174 is pulled to pull the locking pin out of the locking hole. At the same time, the retaining pin 174a is also pulled out of the retaining groove. Rotating the pin cap 174 causes the retaining pin 174a to abut against the end of the retaining seat under the tension of the spring. When the locking pin 172 needs to be engaged with the locking hole again, rotating the pin cap 174 aligns the retaining pin 174a with the retaining groove. Under the tension of the spring, the retaining pin 174a engages with the retaining groove, thereby engaging the locking pin 172 with the locking hole. Of course, the retaining pin 174a can also be positioned on the pin seat 173, and the retaining groove can be positioned on the pin cap 174.

[0091] Optionally, the power switching device provided in this application embodiment further includes a second roller mounting gear 120 coaxially arranged with the first roller mounting gear 1a0. The second roller mounting gear 120 is rotatably engaged with the drive shaft 190. The first roller mounting gear 1a0 is fixed to the second roller mounting gear 120. The diameter of the second roller mounting gear 120 is larger than the diameter of the first roller mounting gear 1a0. The second roller mounting gear 120 is in transmission engagement with the manual drive assembly 130. In this way, the gear engaging with the manual drive assembly 130 and the gear engaging with the internal gear 151 are distinguished, making it less likely for the manual drive assembly 130 to interfere with the movement of the internal gear 151, thus improving the safety of use.

[0092] In one embodiment of this application, the winch 100 includes a roller 110, a rotation drive 180, and a power switching device provided in this application embodiment. The rotation drive 180 is connected to the drive shaft 190 in a transmission manner. The roller 110 is coaxially arranged with the drive shaft 190, and the roller 110 is fixed to the first roller mounting gear 1a0.

[0093] The winch 100 provided in this application embodiment adopts the power switching device provided in this application embodiment. The roller 110 of the winch 100 can be driven by the rotation drive 180 connected to the drive shaft 190, or it can be manually driven by the manual drive assembly 130. This allows the winch 100 to switch between electric drive and manual drive, so that the winch 100 can still perform parachute drying work by manual drive in the event of a power outage.

[0094] In one embodiment of this application, a rotational drive 180, a roller 110, a second roller mounting gear 120, a first roller mounting gear 1a0, a transmission gear 155, a sliding member 156, and a first base 160 are arranged sequentially along the axial direction of the drive shaft 190.

[0095] The manual drive assembly 130 includes a second base 137, a limiting member 13f, a manual drive shaft 135, a pawl 138, a first bushing 133, the second base, and a ratchet assembly 134 fitted onto the first bushing 133.

[0096] The manual drive shaft 135 and the pawl 138 are both mounted on the second base 137. The manual drive shaft 135 is rotatably engaged with the second base 137. The pawl 138 is used to engage with the ratchet assembly 134. The first bushing 133 is threadedly connected to the manual drive shaft 135. The first bushing 133 is used to abut against the ratchet assembly 134 so that rotating the first bushing 133 drives the manual drive shaft 135 to rotate.

[0097] The limiting member 13f cooperates with both the first bushing 133 and the manual drive shaft 135 to limit the relative position between the first bushing 133 and the manual drive shaft 135.

[0098] The rotational fit described in the embodiments of this application is preferably a rotational fit achieved through bearings.

[0099] In this embodiment of the application, the manual drive assembly 130 is used such that the manual drive shaft 135 is driven by the roller 110 of the winch 100. The first bushing 133 is threadedly connected to the manual drive shaft 135. Rotating the first bushing 133 causes it to abut against the ratchet assembly 134. Continuing to rotate the first bushing 133 rotates the manual drive shaft 135, thereby driving the roller 110 to rotate. During the rotation of the ratchet assembly 134 with the manual drive shaft 135, the pawl 138 cooperates with the ratchet assembly 134 to limit the ratchet assembly 134, thereby limiting the manual drive shaft 135. When the roller 110 is driven by an electric motor, the manual drive shaft... 135 will rotate together with roller 110. Before the electric drive is started, the first bushing 133 is rotated first, so that the first bushing 133 moves away from the ratchet assembly 134, thereby allowing the ratchet assembly 134 to rotate freely relative to the manual drive shaft 135. However, during the rotation of the manual drive shaft 135 with the electric drive, the first bushing 133 will generate a certain vibration. The threaded connection between the first bushing 133 and the manual drive shaft 135 may loosen, causing the first bushing 133 to move towards the ratchet assembly 134. This causes the first bushing 133 to abut against the ratchet assembly 134, and the engagement between the ratchet assembly 134 and the pawl 138 takes effect again, hindering the normal operation of the electric drive.

[0100] The manual drive assembly 130 provided in this application, after the first bushing 133 and the ratchet assembly 134 are separated axially from the manual drive shaft 135, cooperates with both the first bushing 133 and the manual drive shaft 135 to limit the relative position between the first bushing 133 and the manual drive shaft 135. This makes it difficult for the first bushing 133 to overcome the limitation and move towards the ratchet assembly 134 and abut against the ratchet assembly 134 even if vibration occurs during the rotation of the manual drive shaft 135. Consequently, the cooperation between the ratchet assembly 134 and the pawl 138 is less likely to be effective during the process of the winch 100 being electrically driven, so that the winch 100 can operate smoothly under electric drive.

[0101] Optionally, the manual drive assembly 130 provided in this application embodiment further includes a second bushing 132, which is coaxially arranged with the first bushing 133 and fixedly connected to the first bushing 133. A shaft end receiving groove 13g is formed on the second bushing 132, which is formed at one end of the second bushing 132 near the first bushing 133. One end of the manual drive shaft 135 is an abutting end located in the shaft end receiving groove 13g. The limiting member 13f is used to abut against both the abutting end and the bottom of the shaft end receiving groove 13g. In this way, the limiting member 13f abuts against the bottom of the abutting end and the bottom of the shaft end receiving groove 13g, making it difficult for the abutting end and the bottom of the shaft end receiving groove 13g to get close, thus limiting the distance between the abutting end and the bottom of the shaft end receiving groove 13g, and consequently limiting the relative position of the second bushing 132 and the manual drive shaft 135. Since the first bushing 133 is fixedly connected to the second bushing 132, the relative position between the first bushing 133 and the manual drive shaft 135 is also limited, making it difficult for the first bushing 133 to move towards the ratchet assembly 134. In this embodiment, the limiting member 13f can be an elastic member or a rigid member. Of course, holes can also be made on the first bushing 133 and the manual drive shaft 135 so that the positioning pin cooperates with the hole to limit the relative position between the first bushing 133 and the manual drive shaft 135.

[0102] Optionally, a through hole is formed on the second bushing 132 to mate with the limiting member 13f. The through hole communicates with the shaft end receiving groove 13g. The limiting member 13f is a rigid member that passes through the through hole and abuts against the abutting end. This facilitates the insertion of the limiting member 13f into the through hole from the outside of the second bushing 132 to abut against the abutting end.

[0103] Optionally, the through hole is a threaded hole 13h extending axially in the manual drive shaft 135, and the limiting member 13f includes a threaded rod 13e, which engages with the threaded hole 13h. Thus, one end of the threaded rod 13e is screwed into the shaft end receiving groove 13g through the threaded hole 13h, and the end of the threaded rod 13e abuts against the abutting end of the manual drive shaft 135, thereby limiting the position between the manual drive shaft 135 and the second bushing 132. Alternatively, the extension direction of the threaded hole 13h can be inclined relative to the axial direction of the manual drive shaft 135, or the through hole can be a pin hole extending radially in the second bushing 132, with a corresponding pin hole also provided in the manual drive shaft 135, and the limiting member 13f is a pin. This pin, by engaging with the pin hole on the manual drive shaft 135 and the pin hole on the second bushing 132, limits the relative position of the manual drive shaft 135 and the second bushing 132.

[0104] Optionally, the limiting member 13f further includes a star-shaped handle 13d, which is fixed to one end of the threaded rod 13e. By providing the star-shaped handle 13d, it is easier for the operator to hold and rotate the threaded rod 13e, thereby facilitating the screwing of the threaded rod 13e into the threaded hole 13h and abutting the abutting end.

[0105] Optionally, the limiting member 13f is an elastic member located within the shaft end receiving groove 13g. Thus, after the second bushing 132 separates from the ratchet assembly 134 axially on the manual drive shaft 135, both the abutting end of the manual drive shaft 135 and the bottom of the shaft end receiving groove 13g abut against the elastic member. Under the elastic force of the elastic member, a locking pressure is generated between the threads on the first bushing 133 and the threads on the manual drive shaft 135, thereby making the threaded connection between the first bushing 133 and the manual drive shaft 135 less prone to failure. Simultaneously, when the first bushing 133 abuts against the ratchet assembly 134, the elastic member is also compressed by the abutting end and the bottom of the shaft end receiving groove 13g, creating pressure between the threads of the first bushing 133 and the threads of the manual drive shaft 135, making the threaded connection between the first bushing 133 and the manual drive shaft 135 less prone to failure.

[0106] Optionally, the first bushing 133 and the second bushing 132 are detachably connected, and the limiting member 13f is detachably connected to the second bushing 132. Thus, when the limiting member 13f is needed to limit the position between the manual drive shaft 135 and the first bushing 133, the limiting member 13f can be placed into the shaft end receiving groove 13g; when the limiting member 13f is not needed to limit the position between the manual drive shaft 135 and the first bushing 133, the limiting member 13f can be removed.

[0107] Optionally, the limiting member 13f is a compression spring, or the limiting member 13f is an elastic pad for filling the shaft end receiving groove 13g. That is, the limiting between the abutting end and the shaft end drive shaft 190 can be achieved by tensioning the compression spring between the abutting end and the bottom of the shaft end receiving groove 13g, or the limiting between the abutting end and the shaft end drive shaft 190 can be achieved by filling the shaft end receiving groove 13g with an elastic pad.

[0108] Optionally, the manual drive assembly 130 provided in this application embodiment further includes a limiting nut 139. The ratchet assembly 134, the first bushing 133, and the limiting nut 139 are arranged sequentially along the axial direction of the manual drive shaft 135, and the limiting nut 139 is fixedly connected to the manual drive shaft 135. By setting the limiting nut 139, the first bushing 133 is less likely to fall off the manual drive shaft 135 when moving away from the ratchet assembly 134. When the manual drive shaft 135 rotates with electric drive, the first bushing 133 can also remain relatively stationary on the manual drive shaft 135.

[0109] The manual drive assembly 130 provided in this embodiment further includes a rotating handle 131. The length direction of the rotating handle 131 is perpendicular to the axial direction of the manual drive shaft 135. The rotating handle 131 is detachably connected to the second bushing 132. Preferably, the ratchet assembly 134 in this embodiment includes a ratchet 13c, two friction discs 13b, and a ratchet seat 13a. The friction discs 13b are annular, and the two friction discs 13b are arranged on both sides of the ratchet 13c in the direction of the manual drive shaft 135. The friction discs 13b are fixedly connected to the ratchet 13c. Both the ratchet 13c and the friction discs 13b are fixed to the ratchet seat 13a. The ratchet seat 13a is fitted onto the manual drive shaft 135, and there is a rotatable engagement between the ratchet seat 13a and the manual drive shaft 135. This rotatable engagement can be achieved through bearings, or by forming a gap between the ratchet seat 13a and the manual drive shaft 135, and achieving the rotatable engagement through this gap.

[0110] In one embodiment of this application, the winch 100 includes a frame 1b0, a roller 110, and a manual drive assembly 130 provided in this application embodiment. The second base 137 is fixed to the frame 1b0, the roller 110 is rotatably engaged with the frame 1b0, and the manual drive assembly 130 further includes a manual drive gear mounted on a manual drive shaft 135, the manual drive gear being in a transmission engagement with the roller 110.

[0111] The winch 100 provided in this application embodiment adopts the manual drive assembly 130 provided in this application embodiment. After the first bushing 133 and the ratchet assembly 134 are separated axially from the manual drive shaft 135, the first bushing 133 cooperates with both the first bushing 133 and the manual drive shaft 135 to limit the relative position between the first bushing 133 and the manual drive shaft 135. This makes it difficult for the first bushing 133 to overcome the limitation and move towards the ratchet assembly 134 and abut against the ratchet assembly 134 even if vibration occurs during the rotation of the manual drive shaft 135. As a result, the cooperation between the ratchet assembly 134 and the pawl 138 is less likely to be effective during the process of the winch 100 being electrically driven, so that the winch 100 can operate smoothly under electric drive.

[0112] In this embodiment, the manual drive shaft 135 drives the manual drive gear 136, which in turn drives the roller 110 to rotate. When the winch 100 is electrically driven, the rotation of the roller 110 will drive the manual drive shaft 135 to rotate through the manual drive gear 136.

[0113] In this embodiment of the application, preferably, the fixed pulley assembly includes a first fixed pulley for fixing to the indoor ceiling and a second fixed pulley for fixing to the indoor wall; preferably, each umbrella drying module includes two traction ropes and two rollers 110, the two traction ropes are wound one-to-one around the two rollers 110, the two rollers 110 are coaxially arranged and fixedly connected to each other, the crossbeam 220 in the umbrella drying device 200 is arranged in a direction perpendicular to the axial direction of the rollers 110, and two connecting seats arranged in the length direction of the crossbeam 220 are provided at the top of the crossbeam 220, the traction rope wound on one roller 110 is connected to one connecting seat on the crossbeam 220, and the traction rope wound on the other roller 110 is connected to the other connecting seat on the crossbeam 220.

[0114] To further improve the control efficiency and convenience of the umbrella drying system, this application also provides a method for visualizing the status of the umbrella drying system, see [link to relevant documentation]. Figure 13 The method for visualizing the status of the umbrella drying system, which can be implemented using a touch screen and a PLC controller, specifically includes the following:

[0115] Step 10: Display different umbrella hanging areas in the current automatic interface, and display the umbrella drying operation attribute information and control function options in each umbrella hanging area in real time; wherein, each umbrella hanging area includes: a circular umbrella hanging area, a wing umbrella hanging area, and a backup umbrella hanging area, the umbrella drying operation attribute information includes: the height of the umbrella drying, the swing working time, and the starting height when hanging the umbrella, and the control function options include: start control function and stop control function for the umbrella drying rising operation, falling operation, and swing operation respectively.

[0116] Specifically, before step 10, the user first starts the PLC controller and the touch screen. After powering on, the user waits for the PLC controller to perform a system self-test, and then the PLC controller controls the touch screen to display a preset welcome screen.

[0117] Then, in step 10, after the user clicks the "Enter System" function option on the welcome screen of the touchscreen, the PLC controller controls the touchscreen to enter the automatic interface. This interface is divided into a circular umbrella hanging area, a wing umbrella hanging area, and a backup umbrella hanging area. It can display the umbrella hanging height, swing working time, starting height, and the start and stop of the three functions of umbrella raising, lowering, and swinging in real time. The starting height is the height when the umbrella is hanging below.

[0118] Step 20: If a background management instruction is received, switch to the background editing interface for displaying umbrella-shaped editing; wherein, the umbrella-shaped editing includes: height calibration, input monitoring, output monitoring, and switching of system parameters.

[0119] Specifically, in step 20, after the user clicks the "Background Management" option displayed on the touch screen, the PLC controller receives the corresponding background management instruction and controls the touch screen to switch to the background editing interface for displaying umbrella-shaped editing, enters umbrella-shaped editing, height calibration, input monitoring, output monitoring, and system parameter switching, where input monitoring and output monitoring are hardware control wiring node I / O ports.

[0120] Step 30: If a swing parameter viewing command is received, switch to the swing parameter interface for displaying the swing parameters, wherein the swing parameters include: the swing start time and the swing duration.

[0121] Specifically, in step 30, after the user clicks the "Swing Parameters" option displayed on the touch screen, the PLC controller receives the corresponding swing parameter viewing instruction and controls the touch screen to switch to the swing parameter interface for displaying the swing parameters. The swing parameters can display the start time of the swing and the duration of the swing.

[0122] In one example, the automatic interface is shown in Figure 14(a), the height calibration display is shown in Figure 14(b), the umbrella editing display is shown in Figure 14(c), the system parameters display is shown in Figure 14(d), the input monitoring display is shown in Figure 14(e), the output monitoring display is shown in Figure 14(f), the swing parameters display is shown in Figure 14(g), and the system log display is shown in Figure 14(h). Here, X and Y are used to identify different numbers, and "#" is used to indicate the Chinese meaning of the number that precedes it and begins with X or Y.
