[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a retractable giant umbrella frame device, including a main pole 1, a telescopic rod 2 slidably connected to the middle of the main pole 1, and a telescopic mechanism installed on the outer side of the main pole 1. The main pole 1 provides support for the telescopic rod 2, and the telescopic mechanism allows the telescopic rod 2 to move inside the main pole 1, thereby adjusting the height of the giant umbrella and facilitating maintenance. An umbrella fabric 3 is fixedly connected to the outer side of the telescopic rod 2, and a support frame 4 is fixedly connected to the outer side of the telescopic rod 2. Reinforcing ribs 5 are fixedly connected to the outer side of the umbrella fabric 3, providing support for the support frame 4 through the telescopic rod 2, allowing it to move more easily. The umbrella fabric 3 unfolds smoothly, allowing the giant umbrella to provide shade and rain protection. The reinforcing ribs 5 enhance the strength of the fabric 3. The telescopic mechanism includes a drive assembly and a transmission assembly. A protective shell 14 is fixedly connected to the outer periphery of the main pole 1. A motor 15 is fixedly connected inside the protective shell 14. A pulley 16 is fixedly connected to the output end of the motor 15. A rotating shaft 17 is rotatably connected to the center of the protective shell 14. A pulley 18 is fixedly connected to the outer side of the rotating shaft 17. Pulley 16 and pulley 18 are connected by a synchronous belt 19. The main pole 1 provides support for the protective shell 14, allowing it to better support the motor 15. For protection, the motor 15 provides power to drive pulley 16 to rotate. Pulley 16 drives pulley 18 to rotate via synchronous belt 19, allowing pulley 18 to drive shaft 17 to rotate in the middle of the protective shell 14. The transmission assembly includes a fixing block 12, which is fixedly connected to the outer periphery of the telescopic rod 2. A pulley 13 is installed on the outer side of the telescopic rod 2. A steel cable 20 is fixedly connected to the top of the fixing block 12 and slidably connected to the outer side of the pulley 13. The other end of the steel cable 20 is fixedly connected to the middle of the shaft 17. The rotation of the shaft 17 drives the steel cable 20 to be extended and retracted by the telescopic rod. 2. Pulley 13 provides support, enabling stable operation. Pulley 13 reduces friction during the extension and retraction of steel cable 20, thus extending its service life. The extension and retraction of steel cable 20 moves fixed block 12, which in turn moves telescopic rod 2 in the middle of main rod 1, thereby adjusting the height of the giant umbrella. The height adjustment of the giant umbrella is achieved through the cooperation of various structures in the telescopic mechanism, eliminating safety hazards for maintenance personnel and facilitating maintenance, thus extending the service life of the giant umbrella.

[0035] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The telescopic rod 2 has a water inlet 29 in its middle. Both the telescopic rod 2 and the main rod 1 have through holes 10 in their middle sections. A water storage tank 21 is fixedly connected to the outside of the main rod 1. Rainwater can enter the telescopic rod 2 and the main rod 1 through the water inlet 29 and reach the water storage tank 21 through the through holes 10, thereby achieving the collection and storage of rainwater. A hydraulic rod 7 is fixedly connected to the middle of the telescopic rod 2. A connecting rod 8 is fixedly connected to the output end of the hydraulic rod 7. A slider 6 is fixedly connected to the end of the connecting rod 8. The slider 6 is slidably connected to the outer periphery of the telescopic rod 2. A support frame 4 is fixedly connected to the outer side of the slider 6. A groove 9 is opened in the middle of the telescopic rod 2. The telescopic rod 2 provides support for the hydraulic rod 7, enabling it to stably provide power to drive the connecting rod 8 to move in the groove 9 of the telescopic rod 2. This causes the connecting rod 8 to drive the slider 6 to move around the outer periphery of the telescopic rod 2, thereby causing the support frame 4 to unfold. The support frame 4 then drives the umbrella fabric 3 to unfold, allowing the giant umbrella to provide sun and rain protection. The middle of the main rod 1 is opened... A water outlet 11 is provided, through which rainwater in the through hole 10 can reach the water storage tank 21. A water pump 23 is fixedly connected to the middle of the water storage tank 21, and a water pump 23 is fixedly connected to the end of the water pump 22. The water pump 23 is fixedly connected to the top of the water storage tank 21, and a water outlet pipe 24 is fixedly connected to the output end of the water pump 23. A valve 25 is installed in the middle of the water outlet pipe 24. A bracket 26 is fixedly connected to the top of the water storage tank 21, and the bracket 26 contacts the water outlet pipe 24, so that the water pump 23 is supported by the water storage tank 21. The system is designed to allow rainwater to be drawn from the water storage tank 21 through the water pumping pipe 22 and discharged through the water outlet pipe 24. The water output is controlled by the valve 25, and the water outlet pipe 24 is supported by the bracket 26 to ensure stable operation. The bottom of the water storage tank 21 is fixedly connected to the mounting base 27, which has mounting holes 28. The mounting base 27 and the mounting holes 28 work together to provide stable support and fixation for the giant umbrella, preventing it from shaking during operation.

[0036] Working principle: When the giant umbrella needs to be unfolded, the hydraulic rod 7 is activated to push the connecting rod 8 to move in the slide groove 9 of the telescopic rod 2. The connecting rod 8 drives the slider 6 to move around the outer periphery of the telescopic rod 2. The slider 6 drives the support frame 4 to unfold, and the support frame 4 drives the umbrella cloth 3 to unfold, thereby achieving the effect of sunshade and rain protection. When the height of the giant umbrella needs to be adjusted, the motor 15 is activated to drive the pulley 16 to rotate. The pulley 16 drives the pulley 18 to rotate through the synchronous belt 19. The pulley 18 drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the steel cable 20 to be extended and retracted. The steel cable 20 slides on the surface of the pulley 13, thereby driving the fixed block 12 to move. The fixed block 12 drives the telescopic rod 2 to move in the middle of the main rod 1, thereby realizing the adjustment of the height of the giant umbrella.

[0037] When it is drizzling, rainwater slides down the umbrella fabric 3 to the inlet 29 of the telescopic pole 2. The rainwater enters the through hole 10 of the telescopic pole 2 and the main pole 1 through the inlet 29, and then flows from the through hole 10 to the outlet 11 of the main pole 1. The rainwater is discharged into the water storage tank 21 through the outlet 11, thus realizing the collection of rainwater. When it is necessary to use the rainwater in the water storage tank 21, the water pump 23 is started, and the rainwater in the water storage tank 21 is pumped out through the water pipe 22 and discharged through the water outlet pipe 24, thus realizing the use of the rainwater in the water storage tank 21.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
