[0037] like Figure 1-15 As shown, the rainwater recovery and filtering device 100 for construction according to an embodiment of the present invention includes a pipe body 110 , a filtering assembly 120 , a driving assembly 130 and a cleaning assembly 140 .

[0038] The tube body 110 has a water inlet 116 and a water outlet 117. The water inlet 116 is arranged above the water outlet 117 and is axially aligned with the water outlet 117 along the tube body 110 (eg, Figure 1 Specifically, Figure 1 and Figure 2 As shown, the tube body 110 can be a vertical tube and extend in the up and down directions, the water inlet 116 is arranged at the upper end of the tube body 110, and the water outlet 117 is arranged at the lower end of the tube body 110, the water inlet 116 can be connected with the foundation pit through a pipeline, and the water outlet 117 can be connected with a water pump, so that rainwater inside the foundation pit flows into the tube body 110 through the water inlet 116, and is pumped into the collection tank from the water outlet 117 through the water pump.

[0039] The filter assembly 120 includes a first filter element 121 and a second filter element 122. The first filter element 121 and the second filter element 122 are both arranged in the tube body 110 and located between the water inlet 116 and the water outlet 117. The first filter element 121 and the second filter element 122 both move relative to the tube body 110 along the axial direction of the tube body 110. The filter assembly 120 rotates relative to the tube body 110 around the radial direction of the tube body 110 at a first position and a second position. In the first position, the first filter element 121 is located between the second filter element 122 and the water inlet 116 so that the first filter element 121 can filter the blockages (for example, stones, mud, etc.) of the rainwater in the tube body 110. In the second position, the second filter element 122 is located between the first filter element 121 and the water inlet 116 so that the second filter element 122 can filter the blockages of the rainwater in the tube body 110. Specifically, as Figure 3As shown, the first filter element 121 and the second filter element 122 can both be filter nets, and the first filter element 121 and the second filter element 122 are arranged in the tube body 110 and are located between the water inlet 116 and the water outlet 117, so that rainwater flows out of the tube body 110 after being filtered by the filter component 120, and the filter component 120 can rotate around the front and rear directions between a first position and a second position. In the first position, the first filter element 121 rotates to the top of the second filter element 122, at which time the first filter element 121 can filter the blockage in the rainwater, and in the second position, the second filter element 122 rotates to the top of the first filter element 121, at which time the second filter element 122 can filter the blockage in the rainwater.

[0040] The driving component 130 is disposed in the tube body 110 and is located between the first filter element 121 and the second filter element 122. The driving component 130 cooperates with the first filter element 121 and the second filter element 122 and has an energy storage state and an energy release state. The rainwater recovery and filtering device 100 for construction has a first state and a second state. In the first state, the first filter element 121 and the second filter element 122 move toward each other under the impact force of rainwater, and the driving component 130 is in an energy storage state to store the impact energy of rainwater. In the second state, the first filter element 121 and the second filter element 122 are offset from each other, and the driving component 130 is in an energy release state to drive the filtering component 120 to rotate between the first position and the second position. Specifically, as Figure 3 As shown, the driving component 130 is arranged between the first filter element 121 and the second filter element 122 and cooperates with the first filter element 121 and the second filter element 122. The working process of the filtering device of the embodiment of the present invention in the first state and the second state is specifically described below with the filtering component 120 in the first position. When the filtering device is in the first state, when the first filter element 121 is blocked, since rainwater will not be able to pass through the first filter element 121, the impact force of rainwater on the first filter element 121 increases, so that the first filter element 121 moves downward, so that the first filter element 121 and the second filter element 122 are close to each other. The driving component 130 is in the energy storage state and can absorb the impact energy of rainwater through the first filter element 121 and store it in the driving component 130. When the filtering device is in the second state, the first filter element 121 and the second filter element 122 are offset, and the driving component 130 can release energy and convert it into kinetic energy to drive the filtering component 120 to rotate, so that the second filter element 122 rotates to the top of the first filter element 121 to ensure the filtering efficiency of the filtering component 120.

[0041] The cleaning assembly 140 is disposed in the tube body 110 and cooperates with the filter assembly 120. In the second state, the cleaning assembly 140 cleans the blockage on the filter assembly 120. Thus, when the first filter element 121 or the second filter element 122 is blocked and rotates, the cleaning assembly 140 can clean the blockage of the first filter element 121 or the second filter element 122 to ensure the filtering efficiency of the filter assembly 120.

[0042] The rainwater recovery and filtering device 100 for construction of the embodiment of the present invention is provided with a filter assembly 120, which can filter rainwater in the foundation pit to prevent blockages in the rainwater from damaging the water pump, thereby extending the service life of the water pump. A driving assembly 130 is provided. When the first filter element 121 is blocked, the impact force of rainwater can be used to flip the filter assembly 120, and the second filter element 122 can be rotated to the top of the first filter element 121, so that the second filter element 122 can play a filtering role again, thereby ensuring the filtering efficiency and filtering effect of the filter assembly 120. There is no need to replace the filter assembly 120, thereby improving the service life of the filter assembly 120, and there is no need to apply additional driving force to the filter assembly 120, thereby reducing the filtering cost of the filter assembly 120. A cleaning assembly 140 is provided, which not only ensures the filtering efficiency of the filter assembly 120, but also enables the filter assembly 120 to be repeatedly used, thereby further reducing the cleaning cost of the rainwater recovery and filtering device 100 for construction.

In the energy storage state, the first filter member 121 and the second filter member 122 move relative to each other to drive the first driving member 131 to move, and the first driving member 131 drives the energy storage member 132 to rotate so that the energy storage member 132 stores energy. Specifically, as Figure 3 and Figure 4 As shown, the first driving member 131 extends in the up-down direction and is located between the first filter element 121 and the second filter element 122. The upper and lower ends of the first driving member 131 cooperate with the first filter element 121 and the second filter element 122 respectively. In the energy storage state, the first filter element 121 moves downward to drive the first driving member 131 to move downward, and the first driving member 131 drives the energy storage member 132 to rotate, so that the energy storage member 132 stores energy.

[0045] The energy storage member 132 is sleeved on the second driving member 133 and connected to the second driving member 133. In the first state, the second driving member 133 is disposed in one of the first filter member 121 and the second filter member 122. The other of the second driving member 133 and the first filter member 121 and the second filter member 122 is spaced apart from the tube body 110 along the axial direction of the tube body 110. In the second state, both ends of the second driving member 133 are respectively connected to the first filter member 121 and the second filter member 122. The energy storage member 132 releases energy to drive the first filter member 121 and the second filter member 122 to rotate through the second driving member 133. Specifically, as Figure 3 and Figure 4 As shown, the energy storage member 132 is arranged on the outer circumferential surface of the second driving member 133 and is connected to the second driving member 133. The following specifically describes the working process of the second driving member 133 in the first state and the second state of the embodiment of the present invention with the filter assembly 120 in the first position. In the first state, the lower side of the second driving member 133 is arranged in the second filter element 122, and the upper side of the second driving member 133 is spaced from the first filter element 121 along the up and down directions.

[0049] When the filter assembly 120 is in the first state and the filter assembly 120 is in the first position, the first filter element 121 drives the first rod 1311 to move along the axial direction of the tube body 110, and the first rod 1311 cooperates with the energy storage element 132 to drive the energy storage element 132 to rotate so that the energy storage element 132 stores energy, or when the filter assembly 120 is in the first state and the filter assembly 120 is in the second position, the second filter element 122 drives the second rod 1312 to move along the axial direction of the tube body 110 so as to drive the energy storage element 132 to rotate so that the energy storage element 132 stores energy. Specifically, Figure 4-Figure 10 As shown, when the filter assembly 120 is located in the first position and the first filter element 121 is blocked, under the impact of rainwater, the first filter element 121 moves downward to drive the first rod 1311 to move downward, and the first rod 1311 cooperates with the energy storage element 132 to drive the energy storage element 132 to rotate, so that the energy storage element 132 starts to store energy; when the filter assembly 120 is located in the second position and the second filter element 122 is blocked, under the impact of rainwater, the second filter element 122 moves downward to drive the second rod 1312 to move downward, and the second rod 1312 cooperates with the energy storage element 132 to drive the energy storage element 132 to rotate, so that the energy storage element 132 starts to store energy.

[0050] In some embodiments, the bottom of the first groove 1211 extends in a direction adjacent to the second groove 1212 and is inclined in a direction away from the second filter element 122. The first rod 1311 can be moved relative to the first groove 1211 in a third position and a fourth position along the extension direction of the groove bottom of the first groove 1211. In the third position, the first rod 1311 is separated from the energy storage element 132. In the fourth position, the first rod 1311 cooperates with the energy storage element 132 so that the first rod 1311 drives the energy storage element 132 to store energy. Specifically, as Figure 4 As shown, the upper end surface of the first groove 1211 is the bottom of the first groove 1211, and the bottom of the first groove 1211 extends from left to right and tilts from bottom to top. The upper end of the first rod 1311 can slide between the third position and the fourth position in the first groove 1211 along the left-right direction. When the filter assembly 120 is in the first position and the first filter element 121 works normally, the first rod 1311 is in the third position (that is, the first rod 1311 is located in the left half of the first groove 1211). At this time, the first rod 1311 1 and the energy storage member 132 are separated. When the first filter element 121 is blocked, under the impact of rainwater, the upper end surface of the first rod 1311 will slide in the first groove 1211 and slide from the third position to the fourth position (that is, the first rod 1311 is located in the right half of the first groove 1211) to make the first rod 1311 and the energy storage member 132 cooperate. Under the impact of rainwater, the first filter element 121 drives the first rod 1311 to move downward to drive the energy storage member 132 to rotate, so that the energy storage member 132 stores energy.

[0051] The bottom of the fourth groove 1222 extends in a direction adjacent to the third groove 1221 and is inclined in a direction away from the first filter element 121. The second rod 1312 can move relative to the fourth groove 1222 along the extension direction of the groove bottom of the fourth groove 1222 in a fifth position and a sixth position. In the fifth position, the second rod 1312 is separated from the energy storage element 132. In the sixth position, the second rod 1312 cooperates with the energy storage element 132 so that the second rod 1312 drives the energy storage element 132 to store energy. Specifically, as Figure 5 As shown, the lower end surface of the fourth groove 1222 is the bottom of the fourth groove 1222, and the bottom of the fourth groove 1222 extends from left to right and tilts from bottom to top, and the lower end of the second rod 1312 can slide in the fourth groove 1222 along the left and right direction between the fifth position and the sixth position. When the filter assembly 120 is in the second position and the second filter element 122 works normally, the second filter element 122 is located above the first filter element 121, and the second rod 1312 is in the fifth position. At this time, the second rod 1312 and the energy storage element 132 are separated. When the second filter element 122 is blocked, under the impact of rainwater, the second rod 1312 will slide in the fourth groove 1222 and slide from the fifth position to the sixth position. The second rod 1312 cooperates with the energy storage element 132, and under the impact of rainwater, the second filter element 122 drives the second rod 1312 to move downward to drive the energy storage element 132 to rotate, so that the energy storage element 132 stores energy.

The first slide bar 150 is arranged in the first groove 1211 and the first slide bar 150 extends in the direction adjacent to the second groove 1212 and is inclined in the direction away from the second filter element 122. The first rod 1311 is penetrated on the first slide bar 150 and moves on the first slide bar 150 so that the first rod 1311 is installed in the first groove 1211 through the first slide groove. The second slide bar 151 is penetrated in the fourth groove 1222 and extends in the direction adjacent to the third groove 1221 and is inclined in the direction away from the first filter element 121. The second rod 1312 is penetrated on the second slide bar 151 and moves on the second slide bar 151 so that the second rod 1312 is installed in the fourth groove 1222 through the second slide groove. Specifically, the extension direction of the first slide bar 150 is the same as the extension direction of the bottom of the first groove 1211, and the extension direction of the second slide bar 151 is the same as the bottom of the fourth groove 1222. Thus, it can be ensured that the first rod 1311 and the second rod 1312 are respectively installed in the first groove 1211 and the fourth groove 1222.

The two ends of the second elastic member 1314 are respectively connected to the lower end surface of the third groove 1221 and the lower end surface of the first rod 1311, and the second elastic member 1314 is always in a compressed state, so that the second elastic member 1314 always has a second elastic force to drive the second rod 1312 to move upward.

[0056] The third elastic member 1315 is disposed in the fourth groove 1222 and the two ends of the third elastic member 1315 are respectively connected to the inner circumference of the fourth groove 1222 and the second rod 1312. The third elastic member 1315 has a third elastic force that drives the second rod 1312 to move from the sixth position toward the fifth position. Figure 5 and Figure 7 As shown, the third elastic member 1315 is a compression spring and is arranged in the fourth groove 1222. The two ends of the third elastic member 1315 are respectively connected to the left end surface of the fourth groove 1222 and the left end surface of the second rod 1312, and the third elastic member 1315 is always in a compressed state, so that the third elastic member 1315 always has a third elastic force to drive the first rod 1311 to move from the sixth position toward the fifth position.

[0057] The fourth elastic member 1316 is disposed in the second groove 1212, and the two ends of the second elastic member 1314 are respectively against the second groove 1212 and the other end of the second rod 1312, and the fourth elastic member 1316 has a fourth elastic force that drives the second rod 1312 to move away from the first filter element 121. Specifically, as Figure 5 and Figure 7 As shown, the fourth elastic member 1316 is a compression spring and is arranged in the second groove 1212 and between the second groove 1212 and the second rod 1312. The two ends of the fourth elastic member 1316 are respectively connected to the upper end surface of the second groove 1212 and the upper end surface of the second rod 1312, and the fourth elastic member 1316 is always in a compressed state, so that the fourth elastic member 1316 always has a fourth elastic force to drive the second rod 1312 to move downward.

[0059] The gear 1321 is sleeved on the second driving member 133 and can rotate relative to the second driving member 133 around the extension direction of the second driving member 133. The gear 1321 is located between the first rod 1311 and the second rod 1312, and the first rod 1311 and the second rod 1312 are both provided with a rack 1317 that matches the gear 1321. Specifically, Figure 8 , Fig.13 and Fig.15 As shown, the second driving member 133 is a horizontal axis and extends in the front-to-back direction. The gear 1321 is sleeved on the outer circumference of the second driving member 133 and can rotate on the second driving member 133.

When the filter assembly 120 is in the second position and the energy storage member 132 is in the energy storage state, the second rod 1312 descends along with the second filter element 122, the rack 1317 on the second rod 1312 is meshed with the gear 1321, the rack 1317 on the second rod 1312 drives the gear 1321 to rotate, and the gear 1321 drives the fifth elastic member 1322 to twist, so that the impact energy of rainwater is converted into the elastic potential energy of the fifth elastic member 1322. In the energy release state, the fifth elastic member 1322 drives the filter assembly 120 to rotate between the first position and the second position through the second driving member 133.

[0061] In some embodiments, a first matching portion 1213 is provided on the side of the first filter element 121 facing the second driving element 133, a second matching portion 1333 is provided on the second driving element 133, one of the first matching portion 1213 and the second matching portion 1333 is a first groove, the other of the first matching portion 1213 and the second matching portion 1333 is a first protrusion, the first groove and the first protrusion cooperate so that the second driving element 133 drives the first filter element 121 to rotate, and / or, a third matching portion 1223 is provided on the side of the second filter element 122 facing the second driving element 133, a fourth matching portion 1334 is provided on the second driving element 133, one of the third matching portion 1223 and the fourth matching portion 1334 is a second groove, the other of the third matching portion 1223 and the fourth matching portion 1334 is a second protrusion, the second groove and the second protrusion cooperate so that the second driving element 133 drives the second filter element 122 to rotate.

[0062] Specifically, Fig.13 and Fig.14As shown, the following describes the first matching portion 1213, the second matching portion 1333, the third matching portion 1223 and the fourth matching portion 1334 of the embodiment of the present invention in detail with the filter assembly 120 in the first position, the outer peripheral surface of the second driving member 133 is provided with the second matching portion 1333 and the fourth matching portion 1334, the second matching portion 1333 and the fourth matching portion 1334 are arranged opposite to each other in the up and down directions, the first filter element 121 is provided with the first matching portion 1213 at the lower end, the second filter element 122 is provided with the second matching portion 1333 at the upper end, and the first matching portion 1213, the second matching portion 1333, the third matching portion 1334 are provided with the fourth matching portion 1334. The settings of 223 and the fourth matching part 1334 can be set according to actual conditions. For example, the first matching part 1213 and the third matching part 1223 can be the first groove and the second groove respectively, and the first matching part 1213 and the third matching part 1223 can be the first protrusion and the second protrusion respectively. In the second state, the first protrusion is inserted into the first groove, and the second protrusion is inserted into the second groove, so that the second driving member 133 drives the filter assembly 120 to rotate between the first position and the second position, thereby ensuring the stability of the rotation and preventing the outer peripheral surface of the second driving member 133 from slipping with the filter assembly 120.

[0063] In some embodiments, the first filter element 121 and the second filter element 122 are both hemispherical and are symmetrically arranged along the radial direction of the tube body 110, and in the second state, the first filter element 121 and the second filter element 122 are buckled into a spherical shape. Figure 3 , Figure 6 , Fig.12 and Fig.13As shown, the first filter element 121 and the second filter element 122 are symmetrically arranged in the horizontal direction, and the shapes of the first filter element 121 and the second filter element 122 are both hemispherical, so that small stones and mud in rainwater can be accumulated on the hemispherical outer peripheral side along the hemispherical outer peripheral surface, thereby reducing the blocking rate of the first filter element 121 and the second filter element 122, and preventing the first filter element 121 and the second filter element 122 from being completely blocked. The first filter element 121 and the second filter element 122 have the same shape and size, so that the first filter element 121 and the second filter element 122 can be combined into a spherical shape, and the diameter of the outer peripheral surface of the first filter element 121 and the second filter element 122 is substantially equal to the width of the tube body 110. When the filtering device is in the first state, due to the first filter element 121, the second filter element 122 is substantially equal to the width of the tube body 110. A filter element 121 and a second filter element 122 are separated, and the dimension between the first filter element 121 and the second filter element 122 is larger than the inner diameter of the tube body 110, which can ensure that the fifth elastic member 1322 of the energy storage member 132 cannot drive the second driving member 133 to rotate (in other words, the filter assembly 120 cannot be flipped). In the second state, the first filter element 121 and the second filter element 122 are buckled into a spherical shape. Since the dimension between the first filter element 121 and the second filter element 122 is smaller than the inner diameter of the tube body 110, the energy storage member 132 can release energy to drive the second driving member 133 to rotate, so that the first filter element 121 and the second filter element 122 are interchangeable in the tube body 110, which promotes the regeneration of the filter assembly 120 and helps to improve the filtering efficiency of the filter assembly 120.

[0064] In some embodiments, the tube body 110 has a first section 111, a second section 112 and a third section 113 that are connected along its axial direction, the second section 112 is located between the first section 111 and the third section 113 and is connected to the first section 111 and the third section 113, a water inlet 116 is formed at the free end of the first section 111, a water outlet 117 is formed on the third section 113, one of the first filter element 121 and the second filter element 122 is disposed in the first section 111, and the other of the first filter element 121 and the second filter element 122 is disposed in the second section 112.

[0065] Specifically, Fig.12As shown, the first section 111 is arranged above the second section 112 and is connected to the second section 112, the second section 112 is arranged above the third section 113 and is connected to the third section 113, the water inlet 116 is formed at the upper end of the first section 111, and the water outlet 117 is arranged below the third section 113. When the filter assembly 120 is in the first position, the first filter element 121 is arranged in the first section 111, the second filter element 122 is arranged in the second section 112, and the inner circumferential surface of the second section 112 is fitted with the outer circumferential surface of the second filter element 122, so that the second filter element 122 is installed in the tube body 110 through the second section 112. When the filter assembly 120 is in the second position, the first filter element 121 is arranged in the second section 112, the second filter element 122 is arranged in the first section 111, and the inner circumferential surface of the second section 112 is fitted with the outer circumferential surface of the first filter element 121, so that the filter assembly 120 is installed in the tube body 110. Therefore, the internal space of the tube body 110 is reasonably utilized, making the arrangement of the tube body 110 more reasonable.

[0066] In some embodiments, the cleaning assembly 140 includes an annular plate 141 and a blocking member 142 .

[0067] The annular plate 141 is disposed in the second section 112, and the outer circumference of the annular plate 141 is spaced from the inner circumference of the second section 112 to define a cleaning groove 114. The outer circumference of the free end of the annular plate 141 extends from the inside of the tube body 110 toward the outside of the tube body 110 and is inclined in a direction away from the water inlet 116. The outer circumference of the second section 112 is provided with a sewage outlet 115 extending in the radial direction of the tube body 110. The sewage outlet 115 is connected to the cleaning groove 114. In the first position, the annular plate 141 is In the second position, the inner circumferential surface of the annular plate 141 and the end of the second filter element 122 adjacent to the first filter element 121 are fitted together, and the free end of the annular plate 141 is flush with the free end of the second filter element 122. In the second position, the inner circumferential surface of the annular plate 141 and the end of the first filter element 121 adjacent to the second filter element 122 are fitted together, and the free end of the annular plate 141 is flush with the free end of the first filter element 121, so that the annular plate 141 can scrape off the blockage on the filter assembly 120 and flow the blockage into the cleaning tank 114.

[0068] Specifically, Fig. 9As shown, the annular plate 141 can be a rubber plate arranged in the second section 112, the annular plate 141 and the second section 112 are arranged at intervals along the radial direction of the tube body 110 to define an annular cleaning groove 114, the outer peripheral surface of the upper end of the annular plate 141 is a slope, and the outer peripheral surface of the second section 112 is provided with a plurality of sewage outlets 115, and the plurality of sewage outlets 115 are arranged at intervals along the circumference of the tube body 110 and are all connected to the cleaning groove 114. In the first position, the second filter element 122 is arranged in the annular plate 141 and the outer peripheral surface of the second filter element 122 is in contact with the inner peripheral surface of the annular plate 141, and the upper end surface of the annular plate 141 and the second filter element 122 are in contact with each other. The upper end surface of the filter element 122 is flush, and in the second position, the first filter element 121 is arranged in the annular plate 141 and the outer circumference of the first filter element 121 is in contact with the inner circumference of the annular plate 141, and the upper end surface of the annular plate 141 is flush with the upper end surface of the first filter element 121, so that in the second state, the first filter element 121 and the second filter element 122 are buckled into a sphere, and when the first filter element 121 and the second filter element 122 rotate, the upper end surface of the annular plate 141 can scrape off the blockage on the filter assembly 120, thereby cleaning the filter assembly 120 and ensuring the filtering effect of the filter assembly 120. In the second state, rainwater in the pipe body 110 can be discharged from the pipe body 110 through the cleaning groove 114.

[0069] In some embodiments, the blocking member 142 is sleeved on the second section 112 and is movable relative to the second section 112 along the axial direction of the tube body 110, so that when the filter assembly 120 is blocked, the blocking member 142 is separated from the drain port 115, so that the blockage is discharged from the tube body 110 through the drain port 115. Figure 6 and 9 As shown, the blocking member 142 is annular and can be mounted on the second section 112 by means of snap connection, threaded connection, etc. When the filter component 120 works normally, the blocking member 142 can block the sewage outlet 115. At this time, the rainwater recovery and filtration device 100 for construction is performing filtering work. When the filter component 120 is blocked, the blocking member 142 can be moved upward or downward to allow the rainwater in the pipe body 110 to be discharged from the pipe body 110 through the cleaning groove 114. In addition, the blockage on the filter component 120 can also be discharged from the pipe body 110 through the cleaning groove 114 to ensure the cleaning efficiency inside the pipe body 110.

[0070] According to the following Figure 1-Figure 15 The working process of the rainwater recovery and filtering device 100 for construction according to the embodiment of the present invention is described in detail:

[0071] During use, after the first filter element 121 has been used for a period of time, the upper surface of the first filter element 121 is clogged, and the water flow is not smooth, resulting in a greater impact force on the first filter element 121, so that the first filter element 121 moves downward under the impact of sewage, and the first rod 1311 slides from left to right along the bottom of the first groove 1211 (that is, slides from the third position to the fourth position), squeezing the first elastic member 1313, so that the rack 1317 on the first rod 1311 is engaged with the gear 1321. (Only After the filter screen of the first filter element 121 is clogged, the first filter element 121 will move downward. First, the first elastic member 1313 is compressed, so that the rack 1317 is meshed with the gear 1321, and then the second elastic member 1314 and the fourth elastic member 1316 are contracted. As the degree of clogging of the first filter element 121 increases, the first rod 1311 squeezes the second elastic member 1314, and the second rod 1312 squeezes the fourth elastic member 1316, so that the second elastic member 1314 and the fourth elastic member 1316 are contracted. During the contraction of the second elastic member 1314 and the fourth elastic member 1316, the rack 1317 of the first rod 1311 and the gear 1321 are always in meshing state, so the rack 1317 of the first rod 1311 drives the gear 1321 to rotate. During the process of the rack 1317 driving the gear 1321 to rotate, the second driving member 133 cannot rotate before the first filter member 121 and the second filter member 122 are combined into a ball (because the gear 1321 and the second driving member 133 are connected by the fifth elastic member 1321). 2 is connected with the first flange 1331 and the second flange 1332, and because the maximum distance between the first filter element 121 and the second filter element 122 is greater than the inner diameter of the tube body 110 before the first filter element 121 and the second filter element 122 form a ball, the filter assembly 120 cannot be turned over before the first filter element 121 and the second filter element 122 are attached to form a ball); therefore, the rotation of the gear 1321 will act on the fifth elastic member 1322 of the torsion spring, so that the fifth elastic member 1322 stores energy. Until the first filter element 121 and the second filter element 122 are attached to form a round ball, and the second matching portion 1333 and the fourth matching portion 1334 of the second driving member 133 are respectively matched with the first matching portion 1213 of the first filter element 121 and the third matching portion 1223 of the second filter element 122, the inner diameter of the tube body 110 is greater than the diameter of the filter assembly 120, and the energy of the fifth elastic member 1322 that stores energy will be released to drive the second driving member 133 to rotate.

[0072] During the rotation process, the blockage on the upper end of the filter assembly 120 will be scraped off by the upper end surface of the annular plate 141. After the blocked dirt is scraped off, the second filter element 122 will rotate to the upper end. Since the second filter element 122 has little resistance to water, the first rod 1311 is pushed downward by the second elastic force of the second elastic element 1314, and the second rod 1312 is pushed upward by the fourth elastic force of the fourth elastic element 1316. When the second filter element 122 moves upward, due to the clean state of the filter screen, the water flow is not enough to shrink the first elastic element 1313 and the third elastic element 1315. Therefore, the rack 1317 of the second rod 1312 after rotation will not mesh with the gear 1321. At the same time, the first elastic element 1313 is completely restored to prepare for the next reversal.

[0073] When the first filter element 121 moves downward to the position just before fitting, the objects that cannot be filtered (pebbles, mud, etc.) on the circumference of the first filter element 121 are collected through the cleaning groove 114. After a period of use, the pebbles, mud, etc. inside the cleaning groove 114 can be discharged through the sewage outlet 115 by rotating the sealing member 142. After cleaning, the sewage outlet 115 can be sealed by rotating the sealing member 142 to prevent the loss of accumulated water.

[0074] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
