The inner wall of the filter tank 2 is fixedly connected with a partition board 202, and a filter 204 for filtration is installed above the partition board 202. A plurality of threaded rings 203 are arranged on the surface of the partition board 202, and the joint of the filter 204 is threadedly connected to the inner wall of the threaded ring 203;

[0030] A sealing plate 301 is embedded in the outer wall of the filter box 3. The outer wall of the sealing plate 301 facing the inner cavity of the filter box 3 is fixedly connected with a leakage plate 302. An activated carbon layer 303 is arranged above the leakage plate 302. A fixing mechanism for facilitating the disassembly and assembly of the sealing plate 301 is installed on the outer wall of the filter box 3. The fixing mechanism includes fixing brackets 306 fixedly connected to the outer walls of both sides of the filter box 3. Two fixing rods 307 are fixedly connected to the inner wall of the fixing bracket 306 facing the filter box 3. A movable block 308 is slidably connected to the outer walls of the two fixing rods 307. A card block 3011 is fixedly connected to the outer wall of the movable block 308 facing the filter box 3. Card slots 305 are opened on the outer walls of both sides of the sealing plate 301. One end of the card block 3011 away from the movable block 308 penetrates through the filter box 3 and is adaptively clamped with the card slot 305. A spring 309 is sleeved on the outer wall of the fixing rod 307 between the fixing bracket 306 and the movable block 308. A pull rod 3010 is fixedly connected to the outer wall of the middle section of the movable block 308. One end of the pull rod 3010 away from the movable block 308 penetrates through the fixing bracket 306.

[0031] The top outer wall of the filter tank 2 is hinged with a top cover 201. One end of the water guide pipe 5 far from the rainwater collection tank 1 is located between the top cover 201 and the partition plate 202 and is close to the top cover 201. By opening the top cover 201, it is convenient to maintain the interior of the filter tank 2, and rainwater is introduced into the interior of the filter tank 2 through the water guide pipe 5.

[0032] A connection valve 206 is provided on the bottom outer wall of the filter tank 2. One end of the connecting pipe 6 located at the filter tank 2 is installed inside the connection valve 206. A first water pump 8 is installed on the top outer wall of the filter box 3. The water delivery end of the first water pump 8 extends into the interior of the filter box 3. One end of the connecting pipe 6 far from the connection valve 206 is connected to the water suction end of the first water pump 8.

[0033] One end of the water delivery pipe 7 located at the filter box 3 is close to the bottom inner cavity of the filter box 3. A second water pump 9 is fixedly installed on the top outer wall of the water storage tank 4. The water delivery end of the second water pump 9 extends into the inner cavity of the water storage tank 4. One end of the water delivery pipe 7 far from the filter box 3 is connected to the water suction end of the second water pump 9. A drain valve 401 is provided on the outer wall of the water storage tank 4 near the bottom inner cavity. The drain valve 401 can be connected to different water-using devices according to actual needs, such as a toilet flushing system, an irrigation system, etc.

[0034] Above the plurality of threaded rings 203, a sealing ring 205 is provided. The sealing ring 205 is closely attached to the bottom end of the filter 204. After rainwater enters the interior of the filter tank 2, it will be isolated above the partition plate 202. The sealing ring 205 is used to seal the gap between the filter 204 and the threaded ring 203 to prevent rainwater from flowing directly below the partition plate 202 without passing through the filtration of the filter 204.

[0035] A handle 304 is fixedly connected to one side outer wall of the sealing plate 301 located outside the filter box 3. Through the handle 304, it is convenient to insert and remove the sealing plate 301 on the outer wall of the filter box 3.

[0036] Positioning holes 103 are formed in the upper outer walls at both ends of the mounting plate 102. A plurality of positioning columns 104 are fixedly connected to the bottom outer wall of the grille 101. The plurality of positioning columns 104 are inserted into the inner walls of the plurality of positioning holes 103. Through the insertion of the positioning columns 104 into the positioning holes 103, it is convenient to position the grille 101 above the mounting plate 102.

[0037] The implementation principle of a rainwater collection and utilization device in an embodiment of this application is as follows: When in use, the rainwater collection tank 1 is installed at the eaves of the building roof. Rainwater will directly fall into the rainwater collection tank 1 through the inclined surface of the roof. The rainwater is filtered by the grille 101 to filter out sundries such as leaves and branches, and then is introduced into the filtration tank 2 through the water guide pipe 5 for rough filtration. After the rainwater enters the filtration tank 2, it will be filtered by multiple filters 204. Larger particulate impurities are retained above the partition 202. The filtered rainwater flows through multiple threaded rings 203 to the lower part of the partition 202. Then, the first pump 8 is started. The first pump 8 pumps the roughly filtered rainwater into the filtration box 3 through the connecting pipe 6 for fine filtration. When the rainwater enters the filtration box 3, it will flow to the top of the activated carbon layer 303. The pore structure of the activated carbon layer 303 is used to remove fine particles and suspended substances in the rainwater to ensure that the quality of the rainwater meets the requirements for subsequent utilization;

[0038] The filtered rainwater falls to the bottom inner cavity of the filtration box 3 through the water leakage plate 302. Then, the second pump 9 is started. The rainwater is pumped into the storage tank 4 through the water delivery pipe 7 for storage. The drain valve 401 is connected to the external pipe network, and the stored rainwater is used for non - drinking water requirements inside and outside the building through a water supply pump. For example, by connecting to the toilet flushing system, the rainwater is used for toilet flushing; by connecting to the irrigation system, the rainwater is used to irrigate plants and green spaces; the rainwater can also be used for car washing, toilet flushing and other purposes to reduce the dependence on urban tap water;

[0039] When the filtration tank 2 and the filtration box 3 filter rainwater for a long time, the internal filters 204 and threaded rings 203 will reach a saturated state, and at this time, a clogging phenomenon will occur, reducing the rainwater filtration efficiency. First, open the top cover 201, then rotate the filter 204, and thread - rotate the joint of the filter 204 with the threaded ring 203, so that the filter 204 is separated from the threaded ring 203, and then the filter 204 can be easily disassembled and replaced;

[0040] Then, through the fixing mechanism, pull the two pull rods 3010 outwards. The pull rods 3010 drive the movable block 308 to slide outwards on the outer wall of the fixed rod 307. At this time, the movable block 308 will pull the clamping block 3011 out of the clamping connection with the clamping groove 305, releasing the locking of the sealing plate 301. The water leakage plate 302 and the activated carbon layer 303 can be pulled out of the filter box 3 through the handle 304, and the activated carbon layer 303 can be replaced. After replacement, the sealing plate 301 and the activated carbon layer 303 are inserted into the filter box 3 again. When the sealing plate 301 enters the inner wall of the filter box 3, the outer walls on both sides of the sealing plate 301 will squeeze the inclined surface at the end of the clamping block 3011. The clamping block 3011 can be easily squeezed outwards through the inclined surface. The clamping block 3011 then pushes the movable block 308 outwards to squeeze the two springs 309. The two springs 309 deform to generate elastic force. When the sealing plate 301 completely enters the interior of the filter box 3, that is, when its outer wall is parallel to the front of the filter box 3, the clamping grooves 305 on both sides of the sealing plate 301 will align with the two clamping blocks 3011. At this time, the outer wall of the sealing plate 301 no longer squeezes the clamping block 3011, and the movable block 308 drives the clamping block 3011 to be clamped with the clamping groove 305 under the elastic force of the spring 309, fixing the sealing plate 301 and completing the installation, thus facilitating the replacement of the activated carbon layer 303.
