[0038] The present invention is further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0039] It should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meaning of such terms in this patent can be understood according to specific circumstances.

[0040] Example 1

[0041] This embodiment provides a rainwater collection and recycling device, comprising:

[0042] The collecting assembly comprises a first collecting tube 1, the top end of which is open. Figure 1 , Figure 3 The cross section of the first collecting tube 1 is an arc structure with an arc angle of π, that is, the first collecting tube 1 is equivalent to half of the pipeline, and the opening faces upward. Rainwater falling into the first collecting tube 1 can flow along the inner wall of the first collecting tube 1 to the bottom and be collected.

[0043] The lifting assembly is arranged on the bracket 5, and a first slide groove 501 is opened on the bracket 5. The first slide groove 501 is parallel to the first collecting tube 1. A sliding block 502 is slidably matched in the first slide groove 501. The first end of the first collecting tube 1 is hinged to the sliding block 502, and the second end of the first collecting tube 1 is hinged to the lifting end of the lifting assembly.

[0044] By lifting and lowering the lifting end of the lifting assembly, the angle of the first collecting tube 1 can be adjusted. For example, the first collecting tube 1 is initially in a horizontal state. Since the first end of the first collecting tube 1 is hinged to the sliding block 502, when the second end of the first collecting tube 1 rises, the sliding block 502 gradually approaches the lifting assembly, the first collecting tube 1 tilts, and the tilt angle gradually increases; when the second end of the first collecting tube 1 drops, the sliding block 502 gradually moves away from the lifting assembly, and the tilt angle of the first collecting tube 1 gradually decreases until it returns to the initial horizontal state.

[0045] Among them, the lifting component can be existing technology, for example, the lifting component can be a cylinder, and the cylinder output end faces upward, and the cylinder output end is the lifting end. The lifting and lowering of the second end of the first collecting tube 1 can be achieved by extending and retracting the cylinder output end.

[0046] Based on the above structure, the rainwater collection and recycling device provided in this embodiment can change the horizontal height of the second end of the first collecting pipe 1 and thus change the angle of the first collecting pipe 1 by lifting and lowering the lifting end of the lifting assembly when collecting rainwater.

[0047] On the one hand, for rainfall in different directions, its collection range can be increased. For example, for rainwater falling vertically, when the first collecting tube 1 is in a horizontal state, the collection range of the first collecting tube 1 is the largest; for rainwater falling obliquely to the right, the horizontal height of the second end of the first collecting tube 1 is higher than the first end, so that the top opening of the first collecting tube 1 is obliquely upward to the left, so that the collection range of the first collecting tube 1 is the largest; for rainwater falling obliquely to the left, the horizontal height of the second end of the first collecting tube 1 is lower than the first end, so that the top opening of the first collecting tube 1 is obliquely upward to the right, so that the collection range of the first collecting tube 1 is the largest. Among them, the lifting range of the lifting end of the lifting assembly should be large enough so that the inclination angle range of the first collecting tube 1 is large enough.

[0048] On the other hand, by changing the angle of the first collecting tube 1, the rainwater collected by the first collecting tube 1 can flow away quickly, avoiding the rainwater remaining in the first collecting tube 1 for a long time, resulting in less rainwater evaporation, etc., and effectively improving the rainwater collection efficiency.

[0049] In this embodiment, the bracket 5 can be arranged on the roof of the building or the external side wall of the building, so that the first collecting pipe 1 can collect rainwater on the roof of the building or the external side wall of the building.

[0050] In order to further improve the collection range of the first collection tube 1, the collection assembly may further include a guide plate 104, see Figure 2 The guide plate 104 is disposed at the top opening of the first collecting tube 1. The guide plate 104 may be a funnel-shaped structure that gradually narrows from top to bottom, effectively increasing the collection range of the first collecting tube 1.

[0051] A filtering structure may be provided at the top opening of the guide plate 104 to play a role of preliminary interception.

[0052] Example 2

[0053] Based on Example 1, the rainwater collection and recycling device provided in this embodiment further includes a second collection pipe 101. Please refer to Figure 1 , Figure 3 The second collecting tube 101 is coaxial with the first collecting tube 1 , and the second collecting tube 101 has the same structure as the first collecting tube 1 .

[0054] A second sliding block is slidably matched in the first slide groove 501, a first end of the second collection tube 101 is hinged to the second sliding block, and a second end of the second collection tube 101 is hinged to the lifting end of the lifting assembly. The angle of the second collection tube 101 can be adjusted by the lifting assembly, and its principle is the same as that of the first collection tube 1, which will not be repeated here.

[0055] Based on the above structure, increasing the number of collection pipes can improve the rainwater collection range and avoid the situation where a single collection pipe is too long and inconvenient to transport and install.

[0056] In order to make the second collecting tube 101 and the first collecting tube 1 remain connected, see Figure 4 A connection frame 105 is provided between the second collection tube 101 and the first collection tube 1. The connection frame 105 is fixed to the lifting end of the lifting assembly, and the connection frame 105 is connected to the first collection tube 1 through a connection piece 109. The connection piece 109 is adapted to the first collection tube 1 and the connection frame 105. For example, the connection piece 109 can be a hose or a corrugated tube, and the cross section of the connection piece 109 can also be an arc structure with an arc of π. One end of the connection piece 109 is fixedly attached to the inner wall of the connection frame 105, and the other end of the connection piece 109 is fixedly attached to the inner wall of the first collection tube 1. Similarly, the connection frame 105 is also connected to the second collection tube 101 through the connection piece 109.

[0057] A first connecting plate 107 and a second connecting plate 108 are hinged on the outer wall of the connecting frame 105 . The first connecting plate 107 is hinged to the first collecting tube 1 at one end away from the connecting frame 105 , and the second connecting plate 108 is hinged to the second collecting tube 101 at one end away from the connecting frame 105 .

[0058] Based on the above structure, when the lifting end of the lifting assembly rises, it drives the connection frame 105 to rise, drives the first connection plate 107 to rise, the first connection plate 107 rotates clockwise, and drives the second end of the first collection tube 1 to rise; when the lifting end of the lifting assembly descends, it drives the connection frame 105 to descend, drives the first connection plate 107 to descend, the first connection plate 107 rotates counterclockwise, and drives the second end of the first collection tube 1 to descend. In this process, the connection frame 105 is always connected with the first collection tube 1 through the connecting piece 109.

[0059] Similarly, when the lifting end of the lifting assembly rises, it drives the connection frame 105 to rise, drives the second connection plate 108 to rise, the second connection plate 108 rotates counterclockwise, and drives the second end of the second collection tube 101 to rise; when the lifting end of the lifting assembly descends, it drives the connection frame 105 to descend, drives the second connection plate 108 to descend, the second connection plate 108 rotates clockwise, and drives the second end of the second collection tube 101 to descend. In this process, the connection frame 105 is always connected to the second collection tube 101 through the connecting piece 109.

[0060] In summary, the setting of the connection frame 105 can ensure the continuity of the second collection pipe 101 and the first collection pipe 1, thereby increasing the collection range of the collection pipe and avoiding gaps. For example, when the rainwater collection and recycling device provided in this embodiment is used on the external side wall of a building, two collection pipes can be continuously arranged along the external side wall of the building, and the two collection pipes are connected through the connection frame 105, thereby ensuring the continuity of the collection range.

[0061] In this embodiment, a mounting seat 605 is fixed to the bottom end of the connection frame 105 , and the mounting seat 605 is fixed to the lifting end of the lifting assembly.

[0062] The connection frame 105 and the mounting seat 605 can be fixed by bolts. For example, a fixing plate 110 is fixed to the bottom of the connection frame 105, and a mounting hole is provided on the mounting seat 605. The fixing plate 110 is fixed to the inner wall of the mounting hole by bolts.

[0063] Example 3

[0064] Based on Example 1, see Figure 3 The lifting assembly provided in this embodiment includes a lifting frame 6 and a mounting seat 605. The lifting frame 6 is fixedly arranged on the bracket 5. A second motor 601 and two moving blocks 603 are arranged in the lifting frame 6. A screw rod 602 is coaxially fixed to the power output end of the second motor 601. The two ends of the screw rod 602 are respectively provided with a forward thread and a reverse thread. For example, a clockwise thread is arranged on the outer wall of the left end of the screw rod 602, and a counterclockwise thread is arranged on the outer wall of the right end of the screw rod 602. The two sections of the thread are in opposite directions, namely, a forward thread and a reverse thread, and the dividing line of the two sections of the thread is the middle line of the screw rod 602. That is to say, the forward thread and the reverse thread have the same length and opposite directions.

[0065] The two moving blocks 603 are respectively screwed with the forward thread and the reverse thread of the screw rod 602. A second slide groove is provided on the inner wall of the lifting frame 6, and the moving block 603 slides with the second slide groove. For example, the inner walls on both sides of the lifting frame 6 are provided with second slide grooves, and the second slide groove is parallel to the axis of the screw rod 602. The two outer side walls of the moving block 603 are fixed with protrusions, and the protrusions slide with the second slide groove, so that the moving block 603 can slide along the second slide groove. Among them, the protrusion can be integrally formed with the moving block 603. Similar to the principle of screw transmission, by rotating the screw rod 602, the moving block 603 can be driven to move axially along the screw rod 602. Since the two moving blocks 603 are respectively screwed with the forward thread and the reverse thread of the screw rod 602, when the screw rod 602 rotates, the moving directions of the two moving blocks 603 are opposite.

[0066] A lifting rod 604 is hinged on the moving block 603. One end of the lifting rod 604 away from the moving block 603 is hinged to the mounting seat 605. The other end of the first collecting tube 1 is hinged to the mounting seat 605. In this way, the mounting seat 605 is the lifting end.

[0067] Specifically, a left lifting rod 604 is hinged on the moving block 603 screwed to the left end of the screw rod 602, and a right lifting rod 604 is hinged on the moving block 603 screwed to the right end of the screw rod 602, and the two lifting rods 604 are of the same length, so that the mounting seat 605 is located above the middle line of the screw rod 602. When the screw rod 602 rotates, the two moving blocks 603 are close to each other, and the moving speed is the same, the inclination angles of the two lifting rods 604 gradually increase, the horizontal height of the mounting seat 605 gradually increases, and is always located above the middle line of the screw rod 602, thereby achieving the elevation of the mounting seat 605; conversely, when the screw rod 602 rotates, the two moving blocks 603 are away from each other, and the moving speed is the same, the inclination angles of the two lifting rods 604 gradually decrease, the horizontal height of the mounting seat 605 gradually decreases, and is always located above the middle line of the screw rod 602, thereby achieving the descent of the mounting seat 605.

[0068] In this embodiment, a waterproof cover is provided in the lifting frame 6 , and the waterproof cover is located above the second motor 601 . The waterproof cover can play a waterproof role and prevent rainwater from directly washing the second motor 601 .

[0069] The side walls of the lifting frame 6 are provided with drainage holes, so that the rainwater collected in the lifting frame 6 can be discharged to avoid the rainwater from remaining in the lifting frame 6.

[0070] Example 4

[0071] Based on Example 1, the rainwater collection and recycling device provided in this embodiment also includes a cleaning component, see Figure 3 The cleaning assembly includes a mounting rod 301 and a cleaning plate 302. The mounting rod 301 is rotatably disposed in the first collecting tube 1. The mounting rod 301 is coaxial with the first collecting tube 1. The cleaning plate 302 is fixed to the mounting rod 301. The cleaning plate 302 is radially arranged along the first collecting tube 1. The end of the cleaning plate 302 is gap-matched with the inner wall of the first collecting tube 1.

[0072] When the mounting rod 301 rotates, the cleaning plate 302 can be driven to rotate. The width of the cleaning plate 302 is slightly smaller than the diameter of the first collecting tube 1. When the cleaning plate 302 rotates, the impurities remaining on the inner wall of the first collecting tube 1 can be scraped out. Due to the effect of inertia, the scraped impurities will be thrown out of the first collecting tube 1, thereby achieving the cleaning effect of the first collecting tube 1. In particular, when the cross section of the first collecting tube 1 is arc-shaped and the arc is less than π, the cleaning effect is better.

[0073] In addition, the cleaning plate 302 can also play a shielding role. Specifically, when it is necessary to collect rainwater, the cleaning plate 302 is rotated to a vertical state, and the rainwater can smoothly fall into the first collection tube 1; when it is not necessary to collect rainwater, the cleaning plate 302 is rotated to a horizontal state, and the cleaning plate can play a shielding role to prevent impurities from falling into the first collection tube 1. For example, when the cleaning plate 302 is rotated to a horizontal state, the cross-section of the first collection tube 1 is an arc structure with an arc of π. At this time, the cleaning plate 302 can just cover the top opening of the first collection tube 1, and the first collection tube 1 is dust-proof and protected from impurities falling into the first collection tube 1, which affects the subsequent rainwater collection function of the first collection tube 1.

[0074] The cleaning assembly provided in this embodiment also includes a driving mechanism for driving the mounting rod 301 to rotate.

[0075] The driving mechanism may be a prior art, for example, a rotary motor, which is mounted on the bracket 5, and the power output end of the rotary motor is coaxially fixed with the mounting rod 301, and the rotary motor can drive the mounting rod 301 to rotate, thereby realizing the automatic rotation of the cleaning plate 302, and thus realizing the cleaning and shielding effects on the first collecting tube 1.

[0076] Example 5

[0077] On the basis of Example 4, in this embodiment, the driving mechanism may include a mounting frame 2 , a mounting bracket 201 , a fixing cylinder 202 , a gear ring 203 , a fixing frame 204 , a fixing bracket 210 , and a first motor 211 .

[0078] See also Figure 5-7 The bottom of the installation frame 2 is open, the installation frame 2 is fixed on the inner wall of the first collecting tube 1, and a mounting groove is opened at the bottom of the first collecting tube 1, and the mounting groove is connected with the bottom opening of the installation frame 2.

[0079] The mounting frame 201 is fixed in the mounting frame 2, and a rotation groove is provided on the mounting frame 201, and the fixed cylinder 202 is rotatably inserted in the rotation groove. The fixed cylinder 202 can be coaxially fixed with the mounting rod 301, and the gear ring 203 is coaxially fixedly sleeved on the outside of the fixed cylinder 202. A recessed clearance groove is provided on the wall of the rotation groove, and the clearance groove is adapted to the gear ring 203, and the gear ring 203 is embedded in the clearance groove. For example, the mounting frame 201 is an arc structure, and the arc is greater than π, and the fixed cylinder 202 is rotatably inserted at the center of the mounting frame 201, so that a part of the gear ring 203 is located in the clearance groove, and the other part is exposed outside the mounting frame 201.

[0080] The fixed frame 204 is fixed on the first collecting tube 1. The fixed frame 204 can be in a U-shaped structure, and one end of the fixed frame 204 extends into the installation slot and extends to the bottom of the gear ring 203. The first rotating disk 205, the second rotating disk 206, the third rotating disk 207, and the fourth rotating disk 212 are rotatably installed in the fixed frame 204. The first rotating disk 205, the second rotating disk 206, the third rotating disk 207, and the fourth rotating disk 212 are distributed in a U shape. The first rotating disk 205 and the second rotating disk 206 are connected by a transmission belt 209, the second rotating disk 206 and the third rotating disk 207 are connected by a transmission belt 209, and the third rotating disk 207 and the fourth rotating disk 212 are connected by a transmission belt 209. The fourth rotating disk 212 is coaxially fixed with a gear 208, and the gear 208 is meshed with the gear ring 203.

[0081] The fixing frame 210 is installed on the fixing frame 204 , the first motor 211 is installed on the fixing frame 210 , and the power output end of the first motor 211 is coaxially fixed with the first rotating disk 205 .

[0082] Based on the above structure, the first motor 211 drives the first rotating disk 205 to rotate, drives the second rotating disk 206 to rotate, drives the third rotating disk 207 to rotate, drives the fourth rotating disk 212 to rotate, drives the gear 208 to rotate, drives the gear ring 203 to rotate, and then drives the fixing cylinder 202 to rotate, and then drives the installation rod 301 to rotate. In addition, the fixing frame 204 and the installation frame 2 can play a good protective role to prevent impurities from falling into the inside and affecting the operation of the device transmission system.

[0083] Among them, screw hole plates can be fixed on both sides of the groove wall of the installation groove at the bottom of the first collecting tube 1, and the fixing frame 204 is fixed on the screw hole plate by screws, which can be quickly disassembled and assembled, and is convenient for later maintenance.

[0084] Example 6

[0085] Based on Example 5, see Figure 7-8 A fixed slot is provided on the side wall of the fixed cylinder 202, and a clamping piece 303 is inserted in the fixed slot. The clamping piece 303 is a spline structure. A movable slot 304 is axially provided at one end of the clamping piece 303 away from the fixed cylinder 202. A spring 305 is provided in the movable slot 304. The first end of the mounting rod 301 extends into the movable slot 304, and two ends of the spring 305 respectively abut against the inner wall of the movable slot 304 and the mounting rod 301, and the spring 305 is in a compressed state.

[0086] A stop ring may be coaxially fixedly provided on the outer wall of the mounting rod 301 , and a limiting ring may be coaxially fixedly provided on the inner wall of the movable groove 304 . The limiting ring is used to block the stop ring to prevent the mounting rod 301 from escaping from the movable groove 304 .

[0087] The second end of the mounting rod 301 can be rotatably mounted on the first collecting tube 1 through a bracket, or can be mounted on the first collecting tube 1 in the same manner as the first end of the mounting rod 301 .

[0088] Based on the above structure, when the fixing tube 202 rotates, the clamping member 303 is driven to rotate. Since the spring 305 is in a compressed state, the friction between the spring 305 and the mounting rod 301 enables the mounting rod 301 to rotate when the clamping member 303 rotates.

[0089] When the cleaning plate 302 is subject to a large resistance, the friction between the spring 305 and the mounting rod 301 may not drive the mounting rod 301 to rotate, or may cause the mounting rod 301 to rotate slowly, thereby avoiding accidents. For example, if a large stone falls on the cleaning plate 302, the mounting rod 301 is subject to a large resistance. If the mounting rod 301 rotates suddenly and quickly, the stone may be thrown into the air with great force, causing a collision with the device, or even causing damage to the device, or causing high-altitude throwing in the air, which poses certain safety hazards.

[0090] In addition, the spring 305 is further compressed so that the clamping member 303 can be withdrawn from the fixed clamping slot on the side wall of the fixed cylinder 202, which is convenient for quick installation or removal of the mounting rod 301 and the cleaning plate 302, and is beneficial for subsequent replacement or maintenance.

[0091] Example 7

[0092] Based on Example 1, the rainwater collection and recycling device provided in this embodiment also includes a filtering component, see Figure 7 , Fig. 9 The filter assembly includes a first filter element 4, a conveying frame 402, and a conveying pipe 403. The conveying frame 402 is fixed to the first collecting pipe 1. The bottom of the first collecting pipe 1 is provided with a filter port adapted to the first filter element 4. The filter port is connected to the conveying frame 402 through a connecting pipe 401. The first filter element 4 is arranged at the filter port. The conveying pipe 403 is connected to the conveying frame 402. The first filter element 4 can be a filter net.

[0093] Based on the above structure, rainwater falling into the first collecting pipe 1 can enter the connecting pipe 401 through the first filter element 4, then enter the conveying frame 402, and finally flow away through the conveying pipe 403.

[0094] The bottom of the first collecting tube 1 may be provided with a plurality of filter ports along the axial direction. A first filter element 4 is provided at each filter port, and the plurality of filter ports can improve the efficiency of rainwater entering the conveying frame 402, and when one of the first filter elements 4 is blocked, the other first filter elements 4 can pass normally, avoiding the situation that the rainwater cannot quickly enter the conveying frame 402 due to the blockage of the first filter element 4.

[0095] The delivery pipe 403 is connected to the end of the delivery frame 402 away from the lifting assembly, so that when the first collecting pipe 1 is tilted, it is conducive to the rapid flow of rainwater in the delivery frame 402 into the delivery pipe 403. For example, the delivery pipe 403 is connected to the left end of the delivery frame 402. When the lifting end of the lifting assembly rises, the right end of the first collecting pipe 1 rises, driving the right end of the delivery frame 402 to rise, and the rainwater in the delivery frame 402 quickly flows to the left end and enters the delivery pipe 403.

[0096] In order to avoid interference between the conveying frame 402 and the sliding block 502, a mounting ring 505 is fixed on the outside of the conveying frame 402, and the mounting ring 505 simultaneously surrounds the conveying frame 402 and the first collecting tube 1 on the inside, and a rotating seat 504 is fixed at the bottom end of the mounting ring 505, and the rotating seat 504 can be directly hinged to the sliding block 502.

[0097] The rotating seat 504 may also be hinged with a rotating plate 503 , and the rotating plate 503 is hinged with the sliding block 502 , so that the structure is more flexible.

[0098] The mounting ring 505 can play a protective role to prevent rainwater or impurities from falling around the transmission structure of the sliding block 502, causing the sliding block 502 to be damaged by external impact and affecting its transmission efficiency.

[0099] In this embodiment, a filter cartridge 404 is disposed on the delivery pipe 403, and a second filter element 405 is disposed inside the filter cartridge 404. The second filter element 405 can achieve a secondary filtering effect.

[0100] The second filter element 405 may be a columnar filter mesh with an opening at the top. Fig.10 A second filter element 405 is coaxially fixed at the top of the filter cartridge 404. Rainwater enters the filter cartridge 404, is filtered by the second filter element 405, and then flows into the bottom of the filter cartridge 404 for drainage. The filtered rainwater can be transported to a water tank for storage and used for watering plants, etc., thus realizing the recycling of rainwater. Impurities in the rainwater are intercepted and collected by the second filter element 405. When too many impurities are collected in the second filter element 405, the top end cover of the filter cartridge 404 can be removed to take out the second filter element 405.

[0101] The filter cartridge 404 includes a top end cover and a cartridge body, and the top end cover is mounted on the cartridge body by bolts.
