It means that the city can adapt to environmental changes and cope with natural disasters caused by rain like a sponge, with good elasticity. It can also be called a "water-elastic city". The city can adapt to environmental changes and cope with natural disasters like a sponge. The internationally common term is "low-impact development rainwater system construction". It absorbs, stores, infiltrates and purifies water when it rains. When needed, the stored water will be released and utilized to achieve the free migration of rainwater in the city.

A bearing is connected between the lifting plate 15 and the threaded column 14. A connecting column 16 is fixedly provided at the lower end of the lifting plate 15. A shovel head 3 is provided below the connecting column 16. A shovel-type device is used for digging. The rod body 1 serves as a shovel support rod structure, and the length between the rod body 1 and the shovel head 3 can be adjusted. Specifically, the motor 11 is started to drive the driven side gear 13 to rotate through the driving side gear 12. At this time, under the rotation of the threaded tube 110, the threaded column 14 moves downward, thereby driving the shovel head 3 structure to move downward through the lifting plate 15 and the connecting column 16, thereby completing the adjustment of the shovel length. In this way, it can be used with operators of different heights, and has high versatility.

[0020] A handle 2 is fixedly provided at the upper end of the rod body 1, and a plurality of anti-slip rings are provided on the outer surface of the handle 2. The outer surface of the handle 2 has a large friction force, making it more convenient to hold for digging work.

The limiting tube 17 improves the rotational stability of the threaded tube 110. The limiting posts 18 move up and down in the limiting grooves 19, so that the lifting plate 15 will not rotate relative to the rod body 1 when it is lifted or lowered, thereby improving the stability during length adjustment.

[0022] Embodiment 2: Figure 3As shown, a mounting plate 31 is fixedly provided at the lower end of the connecting column 16, a support plate 32 is attached to the lower end of the mounting plate 31, and the lower end of the support plate 32 is fixedly connected to the shovel head 3, a limit block 33 and a plurality of positioning columns 35 are fixedly provided at the lower end of the mounting plate 31, six positioning columns 35 are provided, and the six positioning columns 35 are distributed in a ring array, a block groove 34 and a column groove 36 used for matching the limit block 33 and the positioning column 35 are opened at the upper end of the support plate 32, and three bolts 37 distributed in a ring array are movably inserted together at the upper ends of the mounting plate 31 and the support plate 32, The shovel head 3 is installed and connected through the mounting plate 31 and the supporting plate 32. Specifically, the limit block 33 and the positioning column 35 are inserted into the corresponding block groove 34 and the column groove 36, and then the mounting plate 31 and the supporting plate 32 are fixedly connected by the bolt 37. The installation steps are simple and the connection strength after installation is high, which can effectively support the earth-shoveling structure. The shovel head 3 structure is easy to disassemble and maintain, thus avoiding the embarrassment of having to discard the shovel due to damage to the shovel head 3 structure. In addition, the shovel head 3 structure of different sizes and shapes can be selected according to the soil conditions, further improving the versatility.

[0023] Working principle: A shovel-type device is used for digging work. The rod body 1 is used as a shovel support rod structure, and the length between the rod body 1 and the shovel head 3 can be adjusted. Specifically, the motor 11 is started, and the driven side gear 13 is driven to rotate through the driving side gear 12. At this time, under the rotation of the threaded tube 110, the threaded column 14 moves downward, thereby driving the shovel head 3 structure to move downward through the lifting plate 15 and the connecting column 16, thereby completing the adjustment of the shovel length. In this way, it can cooperate with operators of different heights, and has high versatility;

[0024] The limiting tube 17 improves the rotation stability of the threaded tube 110. The limiting column 18 moves up and down in the limiting groove 19, so that the lifting plate 15 will not rotate relative to the rod body 1 when it is lifted, thereby improving the stability during length adjustment.

[0025] The shovel head 3 is installed and connected through the mounting plate 31 and the supporting plate 32. Specifically, the limit block 33 and the positioning column 35 are inserted into the corresponding block groove 34 and the column groove 36, and then the mounting plate 31 and the supporting plate 32 are fixedly connected by the bolt 37. The installation steps are simple and the connection strength after installation is high, which can effectively support the earth-shoveling structure. The shovel head 3 structure is easy to disassemble and maintain, thus avoiding the embarrassment of having to discard the shovel due to damage to the shovel head 3 structure. In addition, the shovel head 3 structure of different sizes and shapes can be selected according to the soil conditions, further improving the versatility.
