[0011] 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.

[0012] Reference Figures 1-3This utility model provides an embodiment of a giant umbrella tension structure for plaza sunshade, comprising a main pole 1, a folding assembly installed on the outer periphery of the main pole 1, a connecting block 8 fixedly connected to the outer side of the folding assembly, an umbrella fabric 9 fixedly connected to the bottom of the connecting block 8, and an umbrella fabric 9 fixedly connected to the end of the umbrella fabric 9 on the outer periphery of the main pole 1. The main pole 1 provides support for the folding assembly, enabling its stable operation. The connecting block 8 allows the umbrella fabric 9 to connect with the folding mechanism, enabling the folding mechanism to drive the umbrella fabric 9 to unfold and close, thereby achieving the effect of controlling the umbrella body. An extension mechanism is installed in the middle of the main pole 1, allowing the height of the umbrella body to be adjusted, thus making the maintenance and cleaning of the umbrella body more convenient. The extension mechanism includes a telescopic assembly and a drive assembly. The telescopic assembly includes a secondary pole 12, which is slidably connected to the outer periphery of the main pole 1. A screw 13 is rotatably connected to the middle of the secondary pole 12, and the screw 13 is threadedly connected to the middle of the main pole 1. The secondary pole 12 provides support for the main pole 1, enabling it to stably fold. The stacking mechanism provides support, with the auxiliary rod 12 supporting the screw 13 for stable operation. The rotation of the screw 13 drives the main rod 1 to move in the middle of the auxiliary rod 12, thereby adjusting the height of the umbrella. The drive assembly includes a protective shell 16, which is fixedly connected to the outer periphery of the auxiliary rod 12. A worm gear 15 is rotatably connected to the middle of the protective shell 16, and a worm wheel 14 is fixedly connected to the outer periphery of the screw 13. The worm wheel 14 and the worm gear 15 mesh with each other. The protective shell 16 provides protection for the worm wheel 14 and the worm gear 15, extending their service life. Through the cooperation of the worm gear 15 and the worm wheel 14, the screw 13 is driven to rotate, thereby driving the main rod 1 to move and raising or lowering the umbrella. The coordination between the various structures of the extension mechanism enables the adjustment of the umbrella height, making cleaning and maintenance of the umbrella more convenient and improving the efficiency of cleaning and maintenance.

[0013] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The main pole 1 has a water collection hole 10 on its outer side, and a downpipe 11 is installed inside the main pole 1. The downpipe 11 passes through the main pole 1, the secondary pole 12, and the screw 13. The secondary pole 12 has a drain outlet 17 at its bottom, and a water storage tank 18 is fixedly connected to the bottom of the secondary pole 12. A water storage box 19 is slidably connected to the middle of the water storage tank 18. Through the interaction between the umbrella fabric 9 and the water collection hole 10 on the main pole 1, rainwater can flow into the downpipe 11 and then be discharged through the drain outlet 17 at the bottom of the secondary pole 12, thus falling into the water storage box 19 in the water storage tank 18, thereby achieving the purpose of water collection. To improve rainwater collection and storage, the water storage box 19 has a fixing hole 20 at its top. A fixing block 22 is fixedly connected to the top of the water storage tank 18. A fixing rod 21 is slidably connected inside the fixing block 22. The fixing rod 21 and the fixing hole 20 are interlocked. A spring 23 is installed inside the fixing block 22. The fixing block 22 provides support for the fixing rod 21, ensuring stable operation. This, in turn, cooperates with the fixing hole 20 to lock the water storage box 19 in place, preventing displacement during rainwater collection. The spring 23 further ensures this. The fixed rod 21 can be reset after being moved. The folding assembly includes folding umbrella ribs 2, which are installed on the outer periphery of the main rod 1. A slider 3 is rotatably connected to the outer side of the folding umbrella ribs 2. The slider 3 is slidably connected to the outer periphery of the main rod 1, and the main rod 1 provides support for the folding umbrella ribs 2 so that they can operate stably and drive the umbrella fabric 9 to unfold and close. The slider 3 enables the folding umbrella ribs 2 to move, realizing the unfolding and closing actions. A hydraulic rod 5 is fixedly connected to the middle of the main rod 1, and a connecting rod 6 is fixedly connected to the output end of the hydraulic rod 5. The end of the connecting rod 6 is fixed. Connected to the inner side of the slider 3, the main rod 1 provides support for the hydraulic rod 5, enabling it to operate stably. The hydraulic rod 5 provides power to drive the connecting rod 6 to move within the main rod 1, thereby moving the slider 3 and allowing the folding umbrella ribs 2 to operate, thus enabling the umbrella body to unfold and close. A stop block 7 is fixedly connected to the outer periphery of the main rod 1, and a sliding groove 4 is provided on the outer side of the main rod 1. The stop block 7 limits the slider 3, allowing it to move within a specified range, while the sliding groove 4 allows the connecting rod 6 to move inside the main rod 1.

[0014] Working principle: When the sunshade needs to be unfolded, the hydraulic rod 5 is activated to drive the connecting rod 6 to slide in the groove 4 of the main rod 1, thereby moving the slider 3. The slider 3 drives the folding umbrella ribs 2 to unfold, the folding umbrella ribs 2 drive the connecting block 8 to move, and the connecting block 8 drives the umbrella fabric 9 to unfold synchronously with the folding umbrella ribs 2. When the slider 3 moves to the position of the stop block 7, the hydraulic rod 5 stops pushing, allowing the sunshade to be fully unfolded, thus achieving the effect of sunshade and rain protection. When the umbrella needs to be cleaned and maintained, the worm gear 15 is rotated to drive the worm wheel 14 to rotate, and the worm wheel 14 drives the screw 13 to rotate, so that the main rod 1 can move in the middle of the auxiliary rod 12, thereby lowering the height of the main rod 1. When it is lowered to a suitable position, the rotation of the worm gear 15 is stopped, and the umbrella can then be cleaned and maintained.

[0015] When it drizzles, rainwater slides down the umbrella fabric 9 to the vicinity of the main pole 1, enters the downpipe 11 inside the main pole 1 and the auxiliary pole 12 through the water collection hole 10 on the main pole 1, and is then discharged through the drain outlet 17 at the bottom of the auxiliary pole 12. The discharged rainwater falls into the water storage box 19 in the water storage tank 18, thus achieving the effect of collecting and storing rainwater. When it is needed, the water storage box 19 can be unlocked by pulling the fixing rod 21 to disengage it from the fixing hole 20. At this time, the water storage box 19 can be pulled out of the water storage tank 18 by pulling the handle on the outside of the water storage box 19, and the rainwater in the water storage box 19 can be used.

[0016] 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.
