Description

Technical Field

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present application cooperates with the guide roller and the water storage box. As the amount of rainwater inside the water storage box increases, the two guide rollers are driven by the traction rope to rotate synchronously. Under the action of the one-way bearing, the annular filter can only rotate in the same direction, thereby adjusting the position of the annular filter. When the water storage box moves to the horizontal plate, the sealing disk can open the water outlet pipe, so that the rainwater filtered inside the water storage box can flow into the water storage tank. Under the elastic force of the reset spring, the water storage box can be reset, so that the annular filter can intermittently rotate as the rainwater flows into the water storage box, thereby avoiding the annular filter from being blocked.

[0017] 2. In the present application, through the cooperation of the collecting box and the sealing plate, as the annular filter rotates, the garbage on the annular filter can be scraped off by the scraper plate, thereby performing preliminary cleaning of the annular filter, and each strip avoidance groove and the contact position of the annular filter are provided with a rubber pad, which can not only avoid the rigid contact between the annular filter and the rectangular frame and protect the annular filter, but also wipe the surface of the annular filter, thereby performing secondary cleaning of the annular filter; and due to the setting of the annular filter, after the filtering is completed, the annular filter located above can move to the bottom of the annular filter and flip 180° as the annular filter rotates. At this time, the rainwater that has been filtered can reversely flush the annular filter, thereby cleaning the annular filter again.

[0018] 3. The present application is provided with a cleaning plate. As rainwater enters the water storage box, the cleaning plate can rotate along its axis under the action of a synchronous rope, so that the garbage stuck in the first water inlet hole is cut off, thereby avoiding clogging of the intercepting plate; and in this process, the second water inlet hole on the cleaning plate can be intermittently coaxial with the first water inlet hole on the intercepting plate, thereby reducing the amount of rainwater entering the water storage tank. Not only can rainwater accumulate on the intercepting plate to avoid clogging of the intercepting plate by garbage with a certain buoyancy, such as plastic bags, but it can also avoid the balance between the amount of rainwater entering and outflowing from the water storage box, thereby ensuring that the water storage box can move back and forth in the vertical direction.

[0019] 4. The present application is provided with a slow-flow hole, which can enable the rainwater inside the water storage box to be slowly discharged through the slow-flow hole on the sealing disk when no rainwater enters or the rainwater is small. This can not only reduce the squeezing of the return spring, but also reduce the rotation frequency of the annular filter, thereby increasing the service life of the annular filter.

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] See also Figures 1 to 13 As shown, a road drainage structure with water storage function based on the design of sponge city includes a water storage tank 1 arranged underground; it also includes an interception plate 2, a continuous filtering mechanism 3, an adjustment mechanism 4 and a cleaning mechanism 5; a water inlet 11 is arranged on the top of the water storage tank 1, the interception plate 2 is arranged in the water inlet 11, and a plurality of first water inlet holes 21 are arranged on the interception plate 2, and a suction pipe 12 is also arranged on the outer wall of the bottom of the water storage tank 1, and the end of the suction pipe 12 away from the water storage tank 1 extends out of the ground and is provided with a water pump 13; a rectangular frame 14 is arranged on the inner wall of the top of the water storage tank 1, the water inlet 11 is connected with the inside of the rectangular frame 14, and a water storage box 15 is slidably arranged inside the rectangular frame 14, and guide plates 151 are arranged on the outer walls on both sides of the water storage box 15, and each guide plate 151 is provided with a guide hole 152, and two guide columns 141 are mirrored at the lower end of the rectangular frame 14, and the guide columns 141 can be slidably arranged in the corresponding guide holes 152, and each guide column 141 is provided with a limit plate 14 at one end away from the rectangular frame 14 11. Each guide column 141 is sleeved with a return spring 1412, and the return spring 1412 is located between the corresponding guide plate 151 and the limit plate 1411; the bottom of the water storage box 15 is in the shape of a chamfered cone, and a water outlet pipe 153 is arranged at the center of the bottom of the water storage box 15, and a drainage component 16 is arranged in the water outlet pipe 153, which can block and open the water outlet pipe 153 as the water storage box 15 slides; the continuous filtering mechanism 3 is arranged inside the rectangular frame 14; the continuous filtering mechanism 3 includes two guide rollers 31 rotatably arranged on the outer walls of both sides of the rectangular frame 14; the two guide rollers 31 are connected by a ring filter 32, and the outer walls of both sides of the rectangular frame 14 are provided with two strip avoidance grooves 142 for avoiding the ring filter 32; the adjustment mechanism 4 is arranged inside the rectangular frame 14 and when the water storage box 15 moves toward the inner wall of the bottom of the water storage tank 1, the two guide rollers 31 rotate synchronously; the cleaning mechanism 5 is arranged inside the water storage tank 1 and is used to clean impurities on the ring filter 32.

[0041] When it rains, large garbage such as branches and plastic bags are intercepted by the interception plate 2 set at the water inlet 11, so as to prevent them from entering the water storage tank 1; rainwater enters the water storage tank 1 through the first water inlet hole 21, and is secondary filtered by the annular filter screen 32, so that small garbage can be separated from the rainwater. Before this, the water storage box 15 is attached to the lower end of the rectangular frame 14 under the elastic force of the return spring 1412. When the rainwater that has completed the secondary filtration enters the water storage box 15, at this time, the outlet pipe 153 is in a blocked state with the cooperation of the drainage component 16. As the weight increases, the water storage box 15 can overcome the elastic force of the return spring 1412 and move in a direction away from the rectangular frame 14. At this time, with the cooperation of the adjustment mechanism 4, the two guide rollers 31 can rotate synchronously to adjust the position of the annular filter screen 32, so as to prevent the annular filter screen 32 from being blocked by garbage. When the rainwater in the water storage box 15 reaches a certain weight, , the drainage component 16 makes the outlet pipe 153 in an open state, so that the rainwater inside the water storage box 15 can enter the water storage tank 1 through the outlet pipe 153. At this time, due to the loss of rainwater inside the water storage box 15, its weight is reduced. Under the elastic force of the reset spring 1412, the water storage box 15 can move toward the direction close to the rectangular frame 14, thereby resetting. As the rainwater continues to enter, the water storage box 15 can reciprocate in the vertical direction. With the cooperation of the adjustment mechanism 4, the two guide rollers 31 can be synchronously rotated intermittently, so that the annular filter screen 32 can be "adaptively" rotated intermittently with the entry of rainwater, so that the annular filter screen 32 can be fully utilized, improving the filtering effect while ensuring the circulation speed of rainwater; the impurities on the annular filter screen 32 are cleaned by the cleaning mechanism 5, ensuring the cleanliness of the annular filter screen 32 while also improving the service life of the annular filter screen 32.

[0042] See also Figures 9 and 10 As shown, the adjustment mechanism 4 includes a one-way bearing 41 and a traction rope 42; a rotating shaft 311 is provided at the center of both ends of each guide roller 31 along the length direction, and two hinge plates 143 are mirror-imaged on the outer walls on both sides of the rectangular frame 14, and a hinge hole 144 is provided on each hinge plate 143. The rotating shaft 311 is rotatably arranged in the corresponding hinge hole 144, and a one-way bearing 41 is provided on each rotating shaft 311; a first reset torsion spring 312 is also provided on each rotating shaft 311, and the first reset torsion spring 312 is located between the corresponding one-way bearing 41 and the corresponding hinge plate 143; a winding wheel 43 is provided on the outer wall of each one-way bearing 41, and a traction rope 42 is wound around each winding wheel 43, and two connecting plates 154 are mirror-imaged on the outer walls on both sides of the water storage box 15, and one end of each traction rope 42 away from the winding wheel 43 is provided on the corresponding connecting plate 154.

[0043] As rainwater continues to enter, the water storage box 15 can move in a direction away from the rectangular frame 14. During this process, the traction rope 42 on the connecting plate 154 can synchronously pull multiple winding wheels 43 to rotate, and the winding wheel 43 drives the corresponding one-way bearing 41 to rotate, so that the two guide rollers 31 can rotate synchronously, thereby adjusting the position of the annular filter screen 32. When the rainwater inside the water storage box 15 reaches a certain weight, the rainwater inside the water storage box 15 flows into the water storage tank 1 through the drainage assembly 16. Under the torsion of the first reset torsion spring 312, the winding wheel 43 can reel in the traction rope 42, thereby ensuring that the corresponding traction rope 42 can remain in a taut state. Under the cooperation of the elastic force of the reset spring 1412, the water storage box 15 can move toward the direction close to the rectangular frame 14. The one-way bearing 41 is set to ensure that the two guide rollers 31 can only rotate in one direction, so that the annular filter screen 32 can be fully utilized.

[0044] See also Figure 4 , Figures 9 to 13 As shown, the cleaning mechanism 5 includes a collecting box 51 and a sealing plate 52; a strip notch 17 for placing the collecting box 51 is provided on the top of the water storage tank 1, and the collecting box 51 is arranged in the strip notch 17, and the collecting box 51 and the side close to the annular filter screen 32 are provided with a feeding groove 511 connected to the inside of the collecting box 51, and a scraper plate 512 extending toward the annular filter screen 32 is provided in the feeding groove 511, and the scraper plate 512 is in contact with the surface of the annular filter screen 32, and guide plates 513 for guiding magazines are provided on both sides of the scraper plate 512; the sealing plate 52 is provided at the opening end of the collecting box 51, and a supporting plate 514 is slidably provided inside the collecting box 51, and the supporting plate 514 and the sealing plate 52 are mutually connected by a connecting rod 521; a water retaining curtain 1421 is also provided in the strip avoidance groove 142 close to the guide plate 513.

[0045] The scraper plate 512 is set at an angle. As the annular filter screen 32 continues to rotate, impurities on the annular filter screen 32 can be moved out of the rectangular frame 14 through the strip avoidance groove 142. A water retaining curtain 1421 is also provided in the strip avoidance groove 142 near the guide plate 513. The water retaining curtain 1421 can block rainwater, thereby preventing garbage from falling directly into the water storage tank 1. The garbage on the annular filter screen 32 can be scraped off by the scraper plate 512, thereby performing a preliminary cleaning on the annular filter screen 32. The scraped garbage can enter the collection box 51 through the strip notch 17, and the guide plates 513 on both sides of the scraper plate 512 can guide the garbage to prevent it from deviating from the trajectory during movement; at this time, the garbage is located above the supporting plate 514, and the sealing plate 52 can block the open end of the collection box 51, thereby preventing unfiltered rainwater from directly entering the collection box Inside the box 51; when cleaning is needed, the sanitation worker pushes the sealing plate 52 upwards, and under the action of the connecting rod 521, the supporting plate 514 can drive the garbage out of the water storage tank 1, so as to facilitate the sanitation worker to clean up. Each strip avoidance groove 142 and the contact position of the annular filter screen 32 are provided with a rubber pad 1422, which can not only avoid the rigid contact between the annular filter screen 32 and the rectangular frame 14 and protect the annular filter screen 32, but also wipe the surface of the annular filter screen 32, so as to perform a secondary cleaning of the annular filter screen 32; and due to the setting of the annular filter screen 32, after the filtering is completed, the annular filter screen 32 located above can be moved to the bottom of the annular filter screen 32 and turned 180° as the annular filter screen 32 rotates. At this time, the rainwater that has been filtered can reversely flush the annular filter screen 32, so as to clean the annular filter screen 32 again.

[0046] See also Fig.11 and Fig.12 As shown, the drainage assembly 16 includes a blocking plate 161; two rotating holes 1531 are mirror-imaged on the outer wall of each water outlet pipe 153, and two rotating rods 162 are mirror-imaged on the outer wall of each blocking plate 161. The rotating rods 162 are rotatably arranged in the corresponding rotating holes 1531, and an adjusting plate 163 is arranged on the end of each rotating rod 162 extending out of the water outlet pipe 153. A second reset torsion spring 164 is also sleeved on each rotating rod 162, and the second reset torsion spring 164 is located between the corresponding adjusting plate 163 and the outer wall of the water outlet pipe 153. An adjusting rod 165 is also arranged on the outer wall of each adjusting plate 163; a horizontal plate 1413 is arranged on each limit plate 1411, and a rectangular notch 1414 for avoiding the adjusting plate 163 is arranged on each horizontal plate 1413.

[0047] By providing the blocking plate 161, under the torsion of the second reset torsion spring 164, the blocking plate 161 is arranged in a horizontal state, so that the outlet pipe 153 can be blocked. As the amount of rainwater inside the water storage box 15 increases, the water storage box 15 moves toward the direction close to the horizontal plate 1413, and the horizontal plates 1413 on the two limit plates 1411 extend toward the center line of the water storage box 15. As the water storage box 15 moves, the adjusting rod 165 on the adjusting plate 163 contacts the surface of the horizontal plate 1413, so that the blocking plate 161 can overcome the torsion of the second reset torsion spring 164 and flip over. The water outlet pipe 153 can be in an open state. At this time, rainwater inside the water storage box 15 can flow into the water storage tank 1. As the weight inside the water storage box 15 decreases, under the elastic force of the first reset torsion spring 312 and the reset spring 1412, the water storage box 15 can move toward the direction close to the rectangular frame 14, so that the adjusting rod 165 and the horizontal plate 1413 are separated from each other. In this process, the sealing disk 161 can be reset under the torsion of the second reset torsion spring 164, and the water outlet pipe 153 can be re-sealed, so that the water storage box 15 can store rainwater again.

[0048] See also Figures 6 to 8 As shown, a cleaning disc 111 is rotatably provided in the water inlet 11, the cleaning disc 111 is located below the intercepting disc 2, and a plurality of second water inlet holes 112 corresponding to the first water inlet holes 21 are provided on the cleaning disc 111; a connecting shaft 113 is provided at the center of the cleaning disc 111, and a first bevel gear 114 is provided at one end of the connecting shaft 113 away from the cleaning disc 111, and synchronous shafts 145 are rotatably provided on the outer walls of both sides of the rectangular frame 14, and a second bevel gear is provided at one end of each synchronous shaft 145 extending out of the rectangular frame 14. 1451, the first bevel gear 114 is meshed with the two second bevel gears 1451 respectively; a synchronization wheel 1452 is arranged at one end of each synchronization shaft 145 extending out of the rectangular frame 14, a synchronization rope 1453 is wound around each synchronization wheel 1452, and one end of each synchronization rope 1453 away from the synchronization wheel 1452 is arranged on the corresponding guide plate 151; a third reset torsion spring 1454 is also arranged on each synchronization shaft 145, and the third reset torsion spring 1454 is located between the corresponding synchronization wheel 1452 and the outer wall of the rectangular frame 14.

[0049] As the amount of rainwater inside the water storage box 15 increases, the two synchronous shafts 145 can rotate under the action of the synchronous rope 1453, and the two synchronous shafts 145 drive the connecting shaft 113 to rotate through the second bevel gear 1451, so that the cleaning disk 111 can rotate along its axis, so that the garbage stuck in the first water inlet hole 21 is cut off; and in this process, the second water inlet hole 112 on the cleaning disk 111 can be intermittently coaxial with the first water inlet hole 21 on the intercepting disk 2, thereby reducing the amount of rainwater entering the water storage tank 1, which can not only make rainwater accumulate on the intercepting disk 2 to prevent garbage with a certain buoyancy such as plastic bags from clogging the intercepting disk 2, but also avoid the balance between the amount of rainwater entering and outflowing from the water storage box 15, thereby ensuring that the water storage box 15 can move back and forth in the vertical direction.

[0050] See also Fig.13 As shown, a mounting groove 522 is provided at the center of the sealing plate 52 , and a handle 523 is hinged in the mounting groove 522 .

[0051] By providing the handle 523 , the staff only needs to grab the handle 523 and pull it upwards to easily take out the garbage in the collection box 51 .

[0052] See also Figure 1 As shown, the outer wall of the water storage tank 1 is also provided with a connecting pipe 18 connected to the rainwater well.

[0053] By providing a connecting pipe 18 which is connected to a municipal rainwater well, rainwater stored in the water storage tank 1 can be restricted to prevent it from overflowing through the water inlet 11 .

[0054] See also Fig.12 As shown, a slow flow hole 166 is provided at the center of the blocking disk 161 .

[0055] By providing the slow flow hole 166, when no rainwater enters or the rainwater is small, the rainwater inside the water storage box 15 can be slowly discharged through the slow flow hole 166 on the sealing disk 161, which can not only reduce the squeezing of the return spring 1412, but also reduce the rotation frequency of the annular filter 32, thereby increasing the service life of the annular filter 32.

[0056] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they 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 patent shall be subject to the attached claims.
