[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1-8 The present invention provides a technical solution: an energy-saving and environmentally friendly garden rainwater collection and purification device and landscape water replenishment device, comprising a collection tube 1. The collection tube 1, as the main component of the entire device, is responsible for receiving and storing collected rainwater. Its design must take into account stability and durability to ensure that it will not deform or damage during long-term use.

[0035] It is worth noting that the rainwater collection component 2 is located at the top of the collection tube 1 and is mainly responsible for the collection and preliminary filtration of rainwater. The annular support shell 201 is fixedly set on the upper surface of the collection tube 1 to provide stable support for the rainwater collection bucket 203.

[0036] The rubber bellows 202 is fixedly connected to the top of the annular support shell 201 and has a certain elasticity, which can play a buffering role in the rainwater collection process and reduce noise and vibration.

[0037] The rainwater collecting hopper 203 is fixedly connected to the top of the rubber corrugated sleeve 202 and is designed in a funnel shape to collect rainwater more effectively. A first linkage shaft rod 204 is rotatably provided at its bottom.

[0038] The bottom end of the first linkage shaft 204 extends into the interior of the annular support shell 201 and is secured to a plurality of first guide vanes 205. When rainwater flows into the collection hopper, it drives the first linkage shaft 204 and first guide vanes 205 to rotate, thereby initially guiding the rainwater and accelerating its flow into the collection tube 1.

[0039] The impurity removal screen 206 is fixedly arranged on the surface of the rainwater collecting hopper 203 and has a conical structure and is located at the top of the collecting hopper. Its main function is to filter out large particles of impurities in the rainwater, such as leaves, branches, etc.

[0040] It should be noted that the top end of the first linkage shaft 204 extends above the impurity removal screen 206 and is symmetrically supported by two movable frames 207. Strip brushes 208 are fixed to the surfaces of the movable frames 207. These strip brushes 208 are positioned to correspond to and overlap the surface of the impurity removal screen 206. When the first linkage shaft 204 rotates, the strip brushes 208 slide across the surface of the impurity removal screen 206, further cleaning impurities from the screen.

[0041] Support blocks 209 are fixedly mounted on both sides of the annular support shell 201. A limiting sleeve 210 is fixed to the upper surface of the support block 209. A movable support rod 211 is slidably mounted on the inner wall of the limiting sleeve 210. The top of the movable support rod 211 is fixedly connected to the surface of the rainwater collection hopper 203. This structural design enhances the stability of the rainwater collection hopper 203 and prevents it from shaking during the rainwater collection process.

[0042] The interior of the limiting sleeve 210 is provided with a support spring 219 and an electromagnet 215, and a permanent magnet block 216 is provided at the bottom end of the movable support rod 211. When the rainwater collecting bucket 203 collects rainwater, it can drive the water inlet sleeve 212 to slide downward on the surface of the first linkage shaft 204 under the action of gravity, and at the same time drive the movable support rod 211 to move downward inside the limiting sleeve 210. When the movable support rod 211 moves to the bottom of the limiting sleeve 210, the sealing disk 213 and the annular rubber block 216 are 14 is removed from the water inlet sleeve 212, and the rainwater in the rainwater collecting hopper 203 is input into the collecting cylinder 1. At the same time, the electromagnet 215 is used to attract the permanent magnet block 216 for a few seconds so that the rainwater collecting hopper 203 will not reset upward during the drainage process. After the rainwater in the rainwater collecting hopper 203 is emptied, the electromagnet 215 is automatically powered off and the permanent magnet block 216 is released, thereby driving the rainwater collecting hopper 203 to automatically reset upward under the action of the support spring 219, thereby completing the initial collection of rainwater.

[0043] A water inlet sleeve 212 is fixedly mounted at the bottom end of the rainwater collection hopper 203. A first linkage shaft 204 is slidably connected to the inner wall of the water inlet sleeve 212 and can slide up and down within it. A blocking disc 213 is fixed to the surface of the first linkage shaft 204. A ring-shaped rubber block 214 is fixed to the lower surface of the blocking disc 213 and inserted into the interior of the water inlet sleeve 212. This design prevents rainwater from flowing back into the collection tube 1 when not collecting rainwater, thanks to the tight fit between the blocking disc 213 and the ring-shaped rubber block 214.

[0044] It should be noted that a guide shroud 217 is also fixed to the surface of the first linkage shaft 204. This guide shroud 217 is located between the water inlet sleeve 212 and the first guide vane 205. A water inlet hole 218 is formed at the top of the collection tube 1, and its position corresponds to that of the annular support shell 201. When rainwater flows into the collection tube 1 through the water inlet hole 218, it is first guided by the guide shroud 217, further accelerating the inflow of rainwater.

[0045] It's worth noting that the filter assembly 4, located within the collection tube 1, is primarily responsible for further purifying the collected rainwater. This assembly comprises the following components: A filter cartridge 401 is pivotally mounted on the inner bottom wall of the collection tube 1, directly below the water inlet 218. After rainwater flows into the collection tube 1 through the water inlet 218, it first passes through the filter cartridge 401, removing fine impurities and suspended matter.

[0046] Two pairs of extension rods 402 are symmetrically arranged on the inner wall of the collection cylinder 1. A mounting bracket 403 is fixed to the end of each pair of extension rods 402. Rubber scrapers 404 are fixed to the sides of the mounting brackets 403. These scrapers 404 overlap the surface of the filter cylinder 401. As the filter cylinder 401 rotates, the rubber scrapers 404 scrape the surface, removing any impurities and dirt adhering to it.

[0047] The top of the filter screen cartridge 401 is fixed with a limit rod 405, and the top of the limit rod 405 is rotatably connected to the lower surface of the fixing frame. This structural design can ensure the stability of the filter screen cartridge 401 during rotation and prevent it from deflecting or shaking.

[0048] It is worth noting that the replenishment component 3 is set at the bottom of the collection tube 1 and is mainly responsible for transporting the purified rainwater to the landscape water body. This component consists of the following components:

[0049] It should be noted that a bottom plate 5 is fixed to the bottom of the collecting cylinder 1, and four support rods are fixed to the lower surface of the bottom plate 5. These support rods provide a stable support for the entire device.

[0050] The replenishment assembly 3 includes a drainage round box 301 fixedly connected between four support rods, and a drainage pipe 302 is fixedly embedded at the bottom end of the drainage round box 301. The surface of the drainage pipe 302 is fixed with an electromagnetic switch valve, which can be controlled to open and close the electromagnetic switch valve to control the discharge of rainwater.

[0051] It should be noted that a rotating guide tube 303 is fixed to the bottom end of the filter screen cartridge 401. The bottom end of the rotating guide tube 303 extends into the interior of the drainage box 301 and is rotatably connected to the upper surface of the drainage box 301. A stop plate 304 is fixed to the bottom end of the rotating guide tube 303, and a second linkage shaft 305 is fixed to the center of the lower surface of the stop plate 304. A second guide vane 306 is fixed to the surface of the second linkage shaft 305. When the rotating guide tube 303 rotates, the second guide vane 306 drives rainwater to rotate and flow within the drainage box 301, thereby accelerating the drainage process.

[0052] The surface of the limiting plate 304 is provided with a plurality of drainage holes 307, which are used to guide the water in the collection cylinder 1 into the interior of the drainage round box 301. This design ensures that rainwater can flow smoothly into the drainage round box 301 and be discharged into the landscape water body through the drainage pipe 302.

[0053] To drive the rotation of the filter drum 401 and the rotating guide tube 303, the device is also provided with a motor shield 6 and a drive motor 7. The motor shield 6 is fixed to the back of the collection drum 1, and the drive motor 7 is fixed to the inner wall of the motor shield 6. The rotating shaft of the drive motor 7 extends below the motor shield 6 and is fixedly connected to a drive synchronous wheel 8.

[0054] A driven synchronous pulley 9 is fixed to the surface of the rotating flow guide tube 303, with a transmission belt 10 installed between the driving synchronous pulley 8 and the driven synchronous pulley 9. When the drive motor 7 is activated, it drives the driving synchronous pulley 8 to rotate, which in turn, via the transmission belt 10, drives the driven synchronous pulley 9 and the rotating flow guide tube 303 to rotate. Because the filter cartridge 401 is fixedly connected to the rotating flow guide tube 303, the filter cartridge 401 also rotates synchronously.

[0055] Working principle: When using this device, when rain falls, the rainwater will first be collected by the rainwater collection bucket 203 and filtered out large particles of impurities through the impurity removal mesh cover 206. Then, the rainwater flows into the collection tube 1 through the water inlet sleeve 212 and is further purified by the filter mesh tube 401.

[0056] During the rainwater collection process, the first linkage shaft 204 rotates under the impact of rainwater, and drives the first guide blade 205 and the strip brush 208 to rotate synchronously. The strip brush 208 cleans the surface of the impurity removal mesh cover 206 during the rotation process to ensure that the mesh cover is unobstructed.

[0057] When the rainwater inside the collection tube 1 reaches a certain level, the replenishment assembly 3 is activated by controlling the opening of the solenoid valve. At this point, the drive motor 7 is activated, driving the rotating guide tube 303 and the filter drum 401 to rotate. The purified rainwater flows through the rotating guide tube 303 through the drainage holes 307 into the drainage box 301, and is ultimately discharged into the landscape water body through the drainage pipe 302.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
