[0002] With the acceleration of urbanization, cities are facing increasingly serious water shortages and environmental problems. As an important part of urban rainwater management, rainwater harvesting technology aims to effectively collect and utilize rainwater resources and reduce the impact of rainwater runoff on the environment.

[0003] At present, the utilization of rainwater requires filtering the rainwater and discharging it into a water tank for storage. In order to filter the rainwater, a filter plate for filtering impurities such as fallen leaves and garbage is generally placed at the water inlet. However, the impurities on the filter plate will gradually increase over time, which can easily cause the filter plate to be blocked. At the same time, when the temperature is high, the water inside the water tank will evaporate through the filter holes on the filter plate, causing the water inside the water tank to gradually decrease.

DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0032] Embodiment 1: Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, a rainwater filtration and reuse system comprises a water storage tank 1 with an opening on the top surface, a mesh filter plate 2 is fixedly connected to the upper part of the inner wall of the water storage tank 1, the top surface of the mesh filter plate 2 is set to be an arc shape, a cavity is opened in the inner lower part of the mesh filter plate 2, a closed plate 3 is slidably installed inside the cavity of the mesh filter plate 2, a slide groove communicating with the cavity is opened on the bottom surface of the mesh filter plate 2, a right-angled trapezoidal plate 4 is slidably connected inside the slide groove of the mesh filter plate 2, and the top surface of the right-angled trapezoidal plate 4 is fixedly connected to the bottom surface of the closed plate 3;

[0033] The mesh filter plate 2 is evenly and vertically provided with a plurality of filter holes, the sealed plate 3 is provided with through holes corresponding to the filter holes on the mesh filter plate 2 one by one, and a plurality of reset springs are fixedly connected between the side of the sealed plate 3 and the inner side of the cavity of the mesh filter plate 2.

[0034] like Figure 7 As shown, under the driving state of external force, the filter holes on the mesh filter plate 2 and the through holes on the sealing plate 3 are in a connected state, and the return spring is in a compressed state.

[0035] like Figure 8 As shown, in the state without being driven by external force, the filter holes on the mesh filter plate 2 and the through holes on the sealing plate 3 are in a staggered state, and the reset spring is in a natural no-load state.

[0036] like Figure 6As shown, a first driving mechanism for moving the sealing plate 3 is installed on the inner wall of the opposite side of the water tank 1, and the first driving mechanism includes a transmission rod 5, and the end of the transmission rod 5 is coaxially rotatably connected to the first friction disc 6, and the side of the first friction disc 6 is coaxially fixedly connected to a turntable 7, and the side of the turntable 7 is hinged with a connecting plate 8, and the other end of the connecting plate 8 is hinged with a vertically movable contact plate 9, and the contact plate 9 can contact the inclined surface of the right-angle trapezoidal plate 4. A fixed plate 10 is horizontally fixedly connected between the other opposite sides of the water tank 1, and the contact plate 9 is slidably connected to the fixed plate 10, and a limit plate is fixedly connected to the upper part of the side of the contact plate 9, and the limit plate can limit the maximum distance of the contact plate 9 moving downward when it is not affected by external force.

[0037] like Figure 6 As shown, the turntable 7 rotates, and the contact plate 9 moves upward through the connecting plate 8. The upward contact plate 9 prompts the right-angle trapezoidal plate 4 to move, and the sealing plate 3 moves synchronously with the right-angle trapezoidal plate 4. After the right-angle trapezoidal plate 4 moves to one end of the slide groove of the mesh filter plate 2, the return spring is at the maximum compression amount, and the turntable 7 is at Figure 6 In the state shown, no more rotation occurs.

[0038] like Figure 5 As shown, a transmission mechanism is installed on the outer wall of the transmission rod 5, and the transmission mechanism includes a second friction disc 11, a circular plate 12, a limit bar 13 and a compression spring. The second friction disc 11 is slidably connected to the outer wall of the transmission rod 5, the circular plate 12 and the limit bar 13 are fixedly connected to the outer wall of the transmission rod 5, the limit bar 13 is slidably connected to the second friction disc 11, the compression spring is fixedly connected between the second friction disc 11 and the circular plate 12, and the compression spring is sleeved outside the transmission rod 5.

[0039] like Figure 5 As shown, the compression spring is in a compressed state. Under the action of the compression spring, the first friction disc 6 and the second friction disc 11 are in a contact state. The transmission rod 5 drives the turntable 7 to rotate through the friction force between the first friction disc 6 and the second friction disc 11. The friction force between the first friction disc 6 and the second friction disc 11 can overcome the influence of the reaction force. The reaction force includes the elastic force of the reset spring, the gravity of the contact plate 9 and the gravity of the connecting plate 8.

[0040] When the right-angle trapezoidal plate 4 moves one end of the sliding groove of the mesh filter plate 2 and cannot move any further, the first friction disc 6 and the second friction disc 11 rotate relative to each other.

[0041] like Figure 3 As shown, a cleaning mechanism for cleaning filtered impurities is installed on the top surface of the water storage tank 1, and the cleaning mechanism includes a first adapter plate 14, a first rotating shaft 15 is rotatably connected to the upper part of the side of the first adapter plate 14, a connecting rod 16 is fixedly connected to the outer wall of the first rotating shaft 15, and a scraper 17 is fixedly connected to the bottom end of the connecting rod 16;

[0042] like Figure 4 As shown, the side of the water tank 1 is fixedly connected to an installation box 18, and the top surface of the installation box 18 is installed with a second driving mechanism, and the second driving mechanism includes a second adapter plate 19 and a T-shaped plate 30, and the upper part of the second adapter plate 19 is rotatably connected to the second rotating shaft 20, one end of the second rotating shaft 20 is fixedly connected to a crank 21, and the other end of the second rotating shaft 20 is fixedly connected to a plurality of wind cups 25 in a circumferential array, and the side of the crank 21 is fixedly connected to a sliding rod 22, and a straight slot is provided at the lower part of the T-shaped plate 30, and the sliding rod 22 is slidably connected inside the straight slot of the T-shaped plate 30, and the top surface of the T-shaped plate 30 is integrally connected with a rack 23, and the rack 23 is meshed with a spur gear 24, and the spur gear 24 is coaxially fixedly connected to the first rotating shaft 15.

[0043] like Figure 4 As shown, two positioning plates 28 are symmetrically fixedly connected to the top surface of the installation box 18, a positioning slide bar 29 is horizontally fixedly connected between the two positioning plates 28, the lower part of the T-shaped plate 30 is slidably connected to the positioning slide bar 29, and the T-shaped plate 30 is in sliding contact with the bottom surface of the installation box 18.

[0044] like Figure 1 and Figure 3 As shown, when it is in thunderstorm and gale weather, under the action of wind, the wind cup 25 drives the second rotating shaft 20 to rotate, the second rotating shaft 20 drives the crank 21 to rotate, the crank 21 drives the T-shaped plate 30 to reciprocate along the positioning slide bar 29 through the sliding rod 22, the rack 23 reciprocates synchronously with the T-shaped plate 30, and further drives the spur gear 24 to reciprocate, and drives the scraper 17 to move along the arc-shaped top surface of the mesh filter plate 2 through the first rotating shaft 15 and the connecting rod 16 to scrape off impurities on the mesh filter plate 2 to prevent the filter holes on the mesh filter plate 2 from being blocked.

[0045] like Figure 1 and Figure 3 As shown, the central axis of the first rotating shaft 15 is located at the center of the circular arc top surface of the mesh filter plate 2, so that the scraper 17 moves back and forth in an arc along the circular arc top surface of the mesh filter plate 2. A plurality of through holes are provided on the side of the scraper 17 to prevent the scraper 17 from pushing rainwater out of the circular arc top surface of the mesh filter plate 2.

[0046] like Figure 3 As shown, one end of the transmission rod 5 extending to the inside of the installation box 18 is coaxially fixedly connected to the first belt pulley 26, and the outer wall of the second rotating shaft 20 is coaxially fixedly connected to the second belt pulley 27. The first belt pulley 26 and the second belt pulley 27 are driven by a transmission belt, and the transmission belt passes through the installation box 18.

[0047] Through the first belt pulley 26, the second belt pulley 27 and the transmission belt, the transmission rod 5 and the second rotating shaft 20 can rotate synchronously.

[0048] Embodiment 2: Fig. 9 As shown, compared with the first embodiment, the difference is that a motor is used instead of the wind cup 25 as the driving source, the motor is installed on the inner wall of the installation box 18, and the motor output shaft is coaxially fixedly connected with the transmission rod 5.

[0049] Using a motor as a driving source can reduce the impact of environmental conditions. For example, when it rains, the ambient wind is not strong enough to drive the corresponding moving parts.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
