Description

Technical Field

[0001] The utility model relates to the technical field of roof greening, in particular to an automatic water storage and drainage device for roof greening. Background Art

[0002] Roof greening can be broadly understood as a general term for gardening and planting trees and flowers on the roofs, terraces, rooftops, balconies or large artificial rockeries of various ancient and modern buildings and structures. Roof greening is extremely important for increasing urban green space, improving the deteriorating human living environment, opening up human green space, improving people's living conditions, beautifying the urban environment and improving ecological effects.

[0003] Existing roof greening usually requires burying a water storage and drainage board with water storage and drainage functions under the soil layer; it is found during the use of the water storage and drainage board that when it rains, a large amount of water will be discharged through the water storage and drainage board, causing a waste of water resources, resulting in poor practicality.

[0004] A new type of roof greening drainage device is disclosed in the Chinese utility model patent with publication number CN218998970, including a planting block, a drainage board and a water storage mechanism. A planting trough is arranged on the top of the planting block, and a water storage tank is connected to the bottom of the planting trough. The water storage mechanism includes a water pump, a water tank, a filter, a first water supply pipe, a second water supply pipe and a watering pipe. Slide grooves are arranged on the left and right ends of the water tank. The left and right ends of the filter are slidably connected with two groups of slide grooves respectively. The front and rear ends of the filter are respectively fitted with the front and rear ends of the water storage cavity. The input end of the first water supply pipe is connected to the right end of the water storage tank, the output end of the first water supply pipe is connected to the left end of the water storage cavity, the input end of the water pump is connected to the rear end of the water storage cavity, the output end of the water pump is connected to the input end of the second water supply pipe, and the watering pipe is installed at the right end of the planting block, and the output end of the second water supply pipe is connected to the input end of the watering pipe. When watering is needed, start the water pump, which creates negative pressure in the water tank, so that the water in the water storage tank enters the water tank through the first water supply pipe. The filter intercepts the impurity particles in the water, and the filtered water is pumped through the second water supply pipe and the watering pipe to irrigate the plants on the planting layer.

[0005] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: on rainy days or when there is a large amount of water in the planting layer, water will penetrate through the drainage board into the water tank for storage, and a small amount of soil and impurities will be brought into the water storage cavity. The soil and impurities will settle at the bottom of the water tank. However, the input end of the first water supply pipe is connected to the bottom of the right end of the water tank. After long-term use, too much soil and impurities will accumulate at the bottom of the water tank, which will block the input end of the first water supply pipe, making the device unusable.

The water tank 10 is arranged at the bottom of the planting block 11, and is used to collect water that permeates the planting block 11. The water outlet 12 is connected to the water outlet pipe 13, the water tank 14, the water supply pump and the watering pipe 15 in sequence. The watering pipe 15 extends to the top of the planting block 11 and is provided with a nozzle. The outlet end of the water outlet pipe 13 is provided with a pumping pump to pump the water in the water tank 10 into the water tank 14. The watering pipe 15 is connected to the water outlet 12 of the water supply pump, and the water pumped out by the water supply pump is used to irrigate the plants on the planting layer. The bottom surface of the water tank 10 is an inclined surface, and the collecting trough 20 is arranged at the lowest end of the water tank 10, so that the mud and impurities in the water in the water tank 10 are precipitated into the collecting trough 20. A sewage outlet 22 is opened on one side of the bottom of the collecting trough 20. The driving mechanism 30 drives the scraper 21 to scrape the soil and impurities in the collecting trough 20 into the sewage outlet 22 and then discharge them, ensuring the cleanliness of the bottom of the water storage tank 10 and preventing the soil and impurities from clogging the water outlet 12 and making the device unusable.

[0033] Specifically, a guide rod 23 arranged along the length direction of the collecting trough 20 is provided in the collecting trough 20, and a guide hole is opened on the scraper 21.

Rubber rings 211 arranged coaxially with the guide rod 23 are provided on both sides of the scraper 21. The inner wall of the rubber ring 211 abuts against the rod body of the guide rod 23. When the scraper 21 moves, the rubber ring 211 removes the dirt and impurities attached to the guide rod 23, ensuring the smooth movement of the scraper 21. The edge of the scraper 21 abuts against the bottom and wall of the collecting trough 20, increasing the cleaning effect of the scraper 21 on the collecting trough 20.

[0034] Two pulleys 16 are vertically spaced apart on the inner wall of the water storage tank 10 at both ends of the collecting tank 20. The core of the pulley 16 is located on a horizontal plane and is perpendicular to the core direction of the guide rod 23. A belt 17 is wound around the four pulleys 16.

When the rotating assembly 40 drives the screw rod 33 to rotate, it drives the slider 32 to slide on the guide rod 31, thereby driving the belt 17 to move, and then drives the scraper 21 to slide to clean the collection tank 20. A valve 221 is arranged in the sewage outlet 22. When the scraper 21 cleans the soil and impurities in the collection tank 20 to the sewage outlet 22, the valve 221 is opened to discharge the soil and impurities. The discharged soil and impurities can be collected and poured into the planting block 11 to prevent soil and water loss in the planting block 11.

[0035] The rotating assembly 40 is arranged on the screw 33 to drive the screw 33 to rotate. In the specific arrangement, the rotating assembly 40 includes a worm wheel 41 and a worm 43. The worm wheel 41 is coaxially arranged at one end of the screw 33. Two horizontally arranged mounting plates 42 are vertically spaced apart on the inner wall of the water storage tank 10. The worm 43 is vertically rotatably arranged between the mounting plates 42. The worm 43 cooperates with the worm wheel 41. A crank 44 is arranged at the upper end of the worm 43 through the mounting plate 42. The worm 43 is driven to rotate by shaking the crank 44, which drives the worm wheel 41 to rotate, thereby driving the screw 33 to rotate. The worm 43 can also be horizontally rotatably arranged above the worm wheel 41 and cooperate with the worm wheel 41. One end of the worm 43 passes through the side wall of the water storage tank 10 and is provided with a crank 44. The crank 44 is located on the side of the water storage tank 10 and does not occupy the top space of the water storage tank 10, so that the area of ​​the planting block 11 can be larger.

[0036] The water tank 10 is provided with an overflow port 18, the height of which is slightly lower than the height of the rotating assembly 40. When the water level in the water tank 10 is too high, water will be discharged from the overflow port 18 to prevent the rotating assembly 40 from being submerged by too much water in the water tank 10, which may cause the rotating assembly 40 to rust and produce adverse effects. A filter screen 121 is provided at the water outlet 12 to further prevent mud and impurities in the water from entering the water outlet 12 and causing blockage.

[0037] The use principle of an automatic water storage and drainage device for roof greening in the present embodiment is as follows: after long-term use, when there is too much soil and impurities in the collecting tank 20, the crank handle 44 is shaken to drive the worm 43 to rotate, driving the worm wheel 41 and the screw 33 to rotate, thereby driving the slider 32 to slide along the guide rod 31 away from the sewage outlet 22, so that the belt 17 pulls the scraper 21 to slide along the guide rod 23 toward the sewage outlet 22, and pushes the soil and impurities in the collecting tank 20 toward the sewage outlet 22. The rubber ring 211 removes the soil and impurities attached to the guide rod 23 during the sliding process of the scraper 21, and at the same time opens the valve 221, so that the soil and impurities are discharged from the sewage outlet 22, and then the valve 221 is closed to complete the cleaning of the bottom of the water storage tank 10, ensuring that the water outlet 12 will not be blocked, so that the device can operate stably for a long time.

[0038] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments.
