Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, and in particular to a rainwater harvesting device. Background Technology

[0002] Rainwater harvesting systems refer to systems and equipment used to collect, store, and utilize rainwater. These systems typically include rooftop harvesting systems, ground-level harvesting systems, filtration and storage facilities, and distribution systems. The purpose of rainwater harvesting systems is to convert natural precipitation into usable water resources for non-potable purposes such as irrigation, toilet flushing, car washing, fire fighting, and industrial water use.

[0003] Existing rainwater harvesting devices consist of several components, and the park rainwater harvesting system is one of the components of the entire rainwater harvesting system. The rainwater harvesting system for park trash cans is one implementation of the park rainwater harvesting system. On rainy days, the rainwater harvesting device for trash cans can effectively guide rainwater to the storage container, preventing rainwater from accumulating inside the trash can.

[0004] Existing rainwater collection systems for park trash cans require both rainwater collection during rainy days and covering the tops of the open trash cans to prevent rainwater from entering. However, the existing rainwater collection systems do not allow for easy adjustment of the collection mechanism, making it difficult to retract the collection mechanism after rain. This results in the trash cans being unusable after rain and is quite inconvenient to use. Utility Model Content

[0018] (III) Beneficial Effects

[0019] This invention provides a rainwater harvesting device. It has the following beneficial effects:

[0020] 1. By rotating the external threaded cylinder, the upper ratchet disc at the bottom of the external threaded cylinder drives the lower ratchet disc downward to compress the lifting spring, thereby separating the lower ratchet disc from the upper ratchet disc, allowing the external threaded cylinder to rotate normally. When the external threaded cylinder rotates, it drives the internal threaded cylinder to descend, which in turn drives the top cover to descend through the connecting pipe.

The upper surface of the locking blocks has an inclined surface. After cleaning the filter ring, when the filter ring is inserted into the ring groove on the upper surface of the top cover, the filter ring squeezes the inclined surface of the outer surface of the locking blocks, thereby retracting the two locking blocks and installing the filter ring. This facilitates the installation and removal of the filter ring, thus performing preliminary filtration of the collected rainwater. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Example 1

[0032] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a rainwater collection device, including a trash can 2, a base 1 at the bottom of the trash can 2, and a collection component 3 on the outer surface of the trash can 2.

[0033] The collection component 3 includes a lifting spring 308 fixedly installed inside the base 1. A lower ratchet disc 307 is installed on the top of the lifting spring 308. An external threaded cylinder 305 is movably installed on the outer surface of the trash can 2. An upper ratchet disc 306 that cooperates with the lower ratchet disc 307 is fixedly installed at the bottom of the external threaded cylinder 305. An internal threaded cylinder 304 is meshed with the outer surface of the external threaded cylinder 305. Several connecting pipes 302 are fixedly installed on the top of the internal threaded cylinder 304. A top cover 301 is fixedly connected to the top of the connecting pipes 302. A water tank 303 is installed on the outer surface of the internal threaded cylinder 304.

[0034] Specifically, the upper surface of the top cover 301 has an annular groove that mates with the filter ring 401. The inside of the annular groove has a through hole that communicates with the connecting pipe 302. The inside of the internally threaded cylinder 304 has a circular groove that connects the connecting pipe 302 and the water tank 303. The bottom of the water tank 303 has an opening for draining water. Rainwater is guided into the annular groove through the top cover 301, and then guided into the water tank 303 through the through hole inside the annular groove, the connecting pipe 302, and the circular groove inside the internally threaded cylinder 304. The connecting pipe 302 is made of a rigid material, which enables it to support the top cover 301.

[0035] Specifically, the outer surface of the bottom of the trash can 2 has an annular protrusion, and the inner side of the external threaded cylinder 305 has an annular groove that matches the annular protrusion. The outer surface of the top of the trash can 2 has a limiting strip, and the inner side of the internal threaded cylinder 304 has a limiting groove that matches the limiting strip. The external threaded cylinder 305 is limited by the cooperation of the annular protrusion and the annular groove, preventing the external threaded cylinder 305 from driving the upper ratchet ring to press down on the lower ratchet ring under the action of gravity. The internal threaded cylinder 304 is limited by the cooperation of the limiting strip and the limiting groove, preventing the internal threaded cylinder 304 from rotating with the external threaded cylinder 305.

[0036] Specifically, two pedals 309 are fixedly mounted on the outer surface of the lower ratchet disc 307. The outer surface of the base 1 has a rectangular groove for the pedals 309 to move. Through the cooperation of the pedals 309 and the rectangular groove, the user can easily distinguish between the lower ratchet disc 307 and the upper ratchet disc 306 by stepping on the pedals 309, thereby allowing the external threaded cylinder 305 to rotate freely.

[0037] Furthermore, by rotating the external threaded cylinder 305, the upper ratchet disc 306 at the bottom of the external threaded cylinder 305 drives the lower ratchet disc 307 to compress the lifting spring 308 downwards, thereby separating the lower ratchet disc 307 from the upper ratchet disc 306, allowing the external threaded cylinder 305 to rotate normally. When the external threaded cylinder 305 rotates, it drives the internal threaded cylinder 304 to descend, thereby driving the top cover 301 to descend through the connecting pipe 302. The top cover 301 then covers the top opening of the trash can 2, preventing rainwater from entering the trash can 2. After the rainwater falls onto the upper surface of the top cover 301, it falls along the upper surface of the top cover 301 to the position of the filter ring 401, and then... The filter ring 401 filters leaves or other debris, while rainwater enters the water tank 303 through the connecting pipe 302 and the circular groove inside the internal threaded pipe, thus collecting rainwater. The cooperation between the upper ratchet disc 306 and the lower ratchet disc 307 can lock the external threaded cylinder 305 in the direction of rotation that drives the internal threaded cylinder 304 to descend, thereby preventing the internal threaded cylinder 304 from causing the top cover 301 to descend under the action of external force, which would affect the normal use of the trash can 2. The external threaded cylinder 305 is locked in the direction of rotation that drives the internal threaded cylinder 304 to rise by the friction between the gravity of the internal threaded cylinder 304 and the threads on the outer surface of the external threaded cylinder 305.

[0038] Example 2

[0039] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and a filter assembly 4 is provided on the upper surface of the top cover 301.

[0040] The filter assembly 4 includes a filter ring 401 mounted on the upper surface of the top cover 301. Several inserts 403 are fixedly mounted on the outer surface of the top cover 301. Two locking blocks 404 are slidably disposed on the top of the inserts 403. A compression spring 406 is fixedly connected between the two locking blocks 404.

[0041] Specifically, the filter ring 401 has several filter holes for filtration inside, and several baffles 402 are fixedly installed on the upper surface of the filter ring 401. The baffles 402 block the filter holes that are connected to the connecting pipe 302, so as to prevent debris from directly entering the connecting pipe 302 through the connecting holes.

[0042] Specifically, the filter ring 401 has an insertion hole that matches the insertion block 403. A T-shaped limiting block 405 is fixedly installed on the upper surface of the insertion block 403. A limiting groove that matches the T-shaped limiting block 405 is provided on the lower surface of the locking block 404. The sliding direction of the locking block 404 is limited by the T-shaped limiting block 405 to prevent the locking block 404 from being misaligned.

[0043] Specifically, rectangular grooves are provided on the adjacent surfaces of the two locking blocks 404, and the compression spring 406 is fixedly connected to the inner wall of the rectangular groove. A U-shaped frame 407 is fixedly installed on the outer surface of one of the locking blocks 404. The U-shaped frame 407 can be inserted into the rectangular groove on the outer surface of the other locking block 404. The U-shaped frame 407 shields the compression spring 406 exposed after the two locking blocks 404 are separated, reducing the erosion of the compression spring 406 by rainwater. The U-shaped frame 407 can also limit the sliding of the locking block 404.

[0044] Furthermore, by manually compressing the two locking blocks 404, the locking blocks 404 squeeze the compression spring 406, thereby unlocking the filter ring 401 and facilitating its removal. The upper surface of the locking blocks 404 has an inclined surface. After cleaning the filter ring 401, when the filter ring 401 is inserted into the annular groove on the upper surface of the top cover 301, the filter ring 401 squeezes the inclined surface of the outer surface of the locking blocks 404, thereby retracting the two locking blocks 404 and thus installing the filter ring 401.

[0045] Working Principle: When rainwater needs to be collected during rainy days, to prevent rainwater from entering the trash can 2, the external threaded cylinder 305 can be rotated. At this time, the upper ratchet disc 306 at the bottom of the external threaded cylinder 305 drives the lower ratchet disc 307 to compress the lifting spring 308 downward, thereby separating the lower ratchet disc 307 from the upper ratchet disc 306, allowing the external threaded cylinder 305 to rotate normally. When the external threaded cylinder 305 rotates, it drives the internal threaded cylinder 304 to descend, which in turn drives the top cover 301 to descend through the connecting pipe 302. The top cover 301 then covers the top opening of the trash can 2, preventing rainwater from entering the trash can 2. After the rainwater falls onto the upper surface of the top cover 301, it falls along the upper surface of the top cover 301 to the position of the filter ring 401, and then passes through the filter ring 401 to filter leaves or other debris. The trash can 2 filters out debris, while rainwater enters the water tank 303 through the connecting pipe 302 and the circular groove inside the internal threaded pipe, thus collecting rainwater. After the rain ends, when sanitation workers collect rainwater, they can step on the pedal 309 to press down the lower ratchet disc 307, thereby unlocking the upper ratchet disc 306. This rotates the external threaded cylinder 305, causing the internal threaded cylinder 304 to lift the top cover 301 through the connecting pipe 302, thus opening the top opening of the trash can 2. For impurities filtered by the filter ring 401, the two locking blocks 404 can be manually compressed, causing the locking blocks 404 to squeeze the compression spring 406, thereby unlocking the filter ring 401 and making it easy to remove the filter ring 401 to clean the filtered leaves or other impurities, ultimately completing the rainwater collection.
