Description

Technical Field

[0001] The present invention relates to the technical field of rainwater treatment, and more specifically, to an underground rainwater infiltration drainage and collection device. Background Art

[0002] In an underground rainwater system, in order to be able to perform subsequent infiltration drainage of rainwater, it is necessary to use a collection device or system to collect rainwater centrally for subsequent infiltration drainage. For example, a siphon rainwater collection system with the patent publication number CN203961150U includes several groups of siphon rainwater funnels arranged on the roof. The drainage end of each siphon rainwater funnel in each group of siphon rainwater funnels is respectively connected to a suspension pipe arranged inside the roof. The drainage end of each suspension pipe is respectively connected to a drainage vertical pipe arranged on the wall. The drainage end of each drainage vertical pipe is connected to a rainwater collection well. The drainage end of the rainwater collection well is connected to a rainwater treatment tank. The treated water outlet end of the rainwater treatment tank is connected to an external water-using device.

[0003] However, in the above rainwater collection device, during the collection process, due to the unfixed amount of rainwater, during the process of large rainwater volume, because the rainwater converges centrally in the collection device, when the collection device conveys or discharges rainwater, a large amount of gas will be contained in the rainwater due to the impact of the rapid water flow. And the existing collection device uses siphon drainage. Therefore, when facing a large amount of rainwater, because air is irregularly mixed in the rainwater, the rainwater cannot flow continuously, resulting in the gas occupying the pipeline space and destroying the continuity of the liquid column, resulting in the interruption of the siphon or the decrease in the flow rate, and further affecting the subsequent drainage effect. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an underground rainwater infiltration drainage and collection device, which solves the problem that the siphon drainage efficiency of the existing collection device is affected by the interference of gas when facing a large amount of rainwater.

[0008] Preferably, a docking cylinder is installed at the center of the floating disk, and a connecting frame is arranged inside the docking cylinder. The connecting frame is rotatably connected with the docking rod; A plurality of flow guiding plates are arranged on the lower surface of the floating disk, and a plurality of limit grooves are formed on the outer side of the floating disk.

[0009] Preferably, an extension shaft is arranged at the lower end of the rotating shaft. A plurality of impellers are arranged on the shaft body of the extension shaft, an expansion disk is arranged on the shaft body of the rotating shaft, and a plurality of stirring shafts are arranged on the upper surface of the expansion disk.

[0010] Preferably, a support frame is installed on the inner wall of the water storage tank. A plurality of falling openings are formed on the surface of the support frame, a shielding cover is installed inside the support frame, and a plurality of limit columns are arranged on the inner wall of the shielding cover. The limit columns are in limit fit with the limit grooves.

[0011] Preferably, a conical flow guiding cover is installed at the upper end of the shielding cover. A rotating seat is rotatably installed inside the conical flow guiding cover. A collecting cover is arranged at the bottom of the rotating seat. A through communication hole is formed inside the rotating seat, and an auxiliary brush plate is arranged on one side of the rotating seat. The bottom of the auxiliary brush plate is attached to the outer surface of the conical flow guiding cover.

[0012] Preferably, the collecting assembly includes a fixed cover. A docking seat is arranged at the lower end of the fixed cover, and the docking seat is installed inside the docking groove. A plurality of partition plates are arranged inside the fixed cover, and a converging groove is formed at the center of the lower side of the fixed cover.

[0013] Preferably, a rotating rod is rotatably installed at the center of the upper side of the fixed cover. A docking channel is formed inside the rotating rod, an exhaust hole is formed at the upper side of the docking channel, a threaded seat is arranged at the bottom of the rotating rod, and a threaded hole is formed at the upper end of the rotating seat. The threaded hole is rotatably connected with the threaded seat.

[0014] Preferably, a plurality of stress plates are arranged on the shaft body of the rotating rod, the stress plates are located inside the converging groove, and a spiral plate is arranged on the inner wall of the docking channel.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The movement range of the discharge component can be limited by the limit sleeve, and during the movement of the discharge component, the sealing ring is used to seal the moving part to prevent rainwater leakage from affecting the drainage effect. Rainwater is received through the delivery pipe. During the delivery process, when the rainwater flow is too large, the siphon phenomenon of rainwater is achieved through the height difference between the downpipe and the delivery pipe, thereby accelerating the drainage effect. Among them, through the bent pipe, a certain amount of rainwater can be pre-stored inside the delivery pipe to quickly trigger the siphon effect.

[0016] 2. The floating disk can adapt to the current water level of rainwater in the water storage tank, so that rainwater can continuously enter the movable column to ensure the stability of the water inflow during the subsequent siphon process. Among them, as the rainwater falls, the rainwater will contact several impellers, and the rotation speed of the extension shaft is adjusted according to the rainfall. There will be some impurities remaining in the rainwater. If a large amount of impurities are discharged from the downpipe together with the rainwater, the impurities will interfere with the siphon effect. Therefore, the floating disk is used to ensure that the movable column collects the rainwater located in the upper layer, thereby ensuring the stability of the rainwater flow and improving the subsequent siphon drainage effect. 3. During the rotation of the extension shaft, several stirring shafts on the expansion disk will rotate accordingly to stir the rainwater that has just entered the movable column, avoiding the problem that a large amount of air is brought into the rainwater due to the continuous impact of the rainwater, and the air will be randomly distributed in the rainwater. The stirring of the rainwater by the stirring shaft can make the internal air move relatively upward during the falling process of the rainwater, and the air at the port of the movable column is discharged through the docking cylinder. Among them, through the docking cylinder, the floating disk floats on the upper surface of the rainwater, so that the air will be preferentially discharged from the docking cylinder. By reducing the air in the rainwater inside the movable column, the rainwater flow is more stable, ensuring that a large amount of rainwater can be collected in time during the collection process and avoiding the problem that the siphon effect decreases due to the interference of gas, and it can prevent the problem that the siphon effect decreases due to the interference of the air inside the rainwater in the subsequent downpipe and delivery pipe during the siphon process.

[0017] 4. The cooperation of the falling port and the shielding cover can make the rainwater first fall outside the water storage tank, and the internal water level of the water storage tank is adjusted according to the change of the rainfall, avoiding the problem that the rainwater directly enters the delivery pipe, resulting in an intermittent state of rainwater during the drainage process and the siphon effect cannot be continuously maintained. And through the conical deflector, the converged rainwater can be dispersed outward to guide the rainwater. Among them, the auxiliary brush plate is rotatably arranged, so that during the rotation of the auxiliary brush plate, the impurities on the surface of the conical deflector can be cleaned to avoid impurity accumulation to ensure the smoothness of the rainwater collection process. Among them, through the series connection through holes, the air below can be guided upward into the docking channel.

[0018] 5. Through the shielding cover and the conical diversion cover, the air at the docking cylinder can be concentrated below the collection cover. As the rotating rod rotates, the spiral plate arranged on the inner wall of the docking channel also rotates. Through the setting of the force-bearing plate, when rainwater falls, the rotating rod can only rotate to one side. Thus, under the guidance of the spiral plate, the gas below the collection cover is discharged upward and discharged from the exhaust holes, thereby improving the gas discharge efficiency and avoiding interference with the subsequent siphon drainage effect due to the inability to timely discharge the internal gas.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 18 shown, an underground rainwater infiltration drainage and collection device includes a base 1. A delivery pipe 2 is installed at the lower end of the base 1. A bending pipe 201 is connected to one side of the delivery pipe 2. A downward pipe 202 is installed at the lower end of the bending pipe 201. A docking groove 101 is arranged on the upper surface of the delivery pipe 2. A collection assembly 3 for receiving rainwater is installed inside the docking groove 101. A water storage tank 102 is opened inside the base 1. A discharge assembly 4 for discharging rainwater is installed at the upper end of the delivery pipe 2.

[0023] In this embodiment, a limiting sleeve 204 is arranged at the upper end of the delivery pipe 2, and a sealing ring 203 is arranged on the inner wall of the limiting sleeve 204.

[0024] The movement range of the discharge assembly 4 can be limited by the limiting sleeve 204, and the sealing ring 203 is used to seal the moving part during the movement of the discharge assembly 4 to prevent rainwater leakage from affecting the drainage effect. Rainwater is received through the delivery pipe 2. During the delivery process, when the rainwater flow rate is too large, the rainwater siphon phenomenon is realized through the height difference between the downward pipe 202 and the delivery pipe 2, thereby accelerating the drainage effect. Among them, through the bending pipe 201, a certain amount of rainwater can be pre-stored inside the delivery pipe 2 to quickly trigger the siphon effect.

[0025] In this embodiment, the discharge assembly 4 includes a movable column 401, which is movably arranged inside the conveying pipe 2. A mating sleeve 4011 is provided at the lower end of the movable column 401. The mating sleeve 4011 is in limit fit with the limit sleeve 204. A rotating frame 403 is arranged inside the movable column 401. A rotating shaft 404 is rotatably arranged inside the rotating frame 403. A docking rod 407 is provided at the upper end of the rotating shaft 404. A floating disk 402 is arranged above the docking rod 407.

[0026] It should be noted that a docking cylinder 4021 is installed at the center of the floating disk 402. A connecting frame 4024 is arranged inside the docking cylinder 4021. The connecting frame 4024 is rotatably connected to the docking rod 407; A plurality of flow guide plates 4022 are arranged on the lower surface of the floating disk 402. A plurality of limit grooves 4023 are formed on the outer side of the floating disk 402.

[0027] During specific setting, an extension shaft 405 is provided at the lower end of the rotating shaft 404. A plurality of impellers 4051 are arranged on the shaft body of the extension shaft 405. An expansion disk 406 is arranged on the shaft body of the rotating shaft 404. A plurality of stirring shafts 4061 are arranged on the upper surface of the expansion disk 406.

[0028] When a large amount of rainwater enters, the floating disk 402 can adapt to the current water level of the rainwater in the water storage tank 102, so that the rainwater can continuously enter the movable column 401 to ensure the stability of the water inflow during the subsequent siphon process. When the rainwater falls, the rainwater will contact a plurality of impellers 4051, and the rotation speed of the extension shaft 405 is adjusted according to the rainfall. Some impurities will remain in the rainwater. If a large amount of impurities are discharged from the downcomer 202 together with the rainwater, the impurities will interfere with the siphon effect. Therefore, the floating disk 402 ensures that the movable column 401 collects the rainwater in the upper layer, thereby ensuring the stability of the rainwater flow and improving the subsequent siphon drainage effect; During the rotation of the extension shaft 405, a number of stirring shafts 4061 on the expansion disk 406 will rotate accordingly, stirring the rainwater that has just entered the movable column 401, avoiding the problem of a large amount of air being brought into the rainwater due to continuous impact of the rainwater, and the air will be randomly distributed in the rainwater. Using the stirring shafts 4061 to stir the rainwater can make the internal air move relatively upward during the fall of the rainwater, and discharge the air at the port of the movable column 401 through the docking cylinder 4021. Among them, the floating disk 402 floats on the upper surface of the rainwater through the docking cylinder 4021, so that the air will be preferentially discharged from the docking cylinder 4021. By reducing the air in the rainwater inside the movable column 401, the rainwater can flow more stably to ensure that a large amount of rainwater can be collected in time and avoid the problem of poor collection efficiency caused by gas interference, and can make the subsequent downcomer 202 and the conveying pipe 2 avoid the problem of the siphon effect decreasing due to the interference of the air inside the rainwater during the siphon process.

[0029] In this embodiment, a support frame 5 is installed on the inner wall of the water storage tank 102. A number of falling openings 6 are provided on the surface of the support frame 5. A shielding cover 7 is installed inside the support frame 5. A number of limiting posts 8 are provided on the inner wall of the shielding cover 7, and the limiting posts 8 are in limiting cooperation with the limiting grooves 4023.

[0030] In this application, a conical diversion cover 10 is installed at the upper end of the shielding cover 7. A rotating seat 9 is rotatably installed inside the conical diversion cover 10. A collection cover 901 is provided at the bottom of the rotating seat 9. A series of through holes 902 are provided inside the rotating seat 9. An auxiliary brush plate 904 is provided on one side of the rotating seat 9, and the bottom of the auxiliary brush plate 904 is attached to the outer surface of the conical diversion cover 10. By the cooperation of the falling openings 6 and the shielding cover 7, the rainwater will first fall to the outside of the water storage tank 102, and the internal water level in the water storage tank 102 will be adjusted accordingly with the change of the rainfall amount, avoiding the problem that the rainwater directly enters the conveying pipe 2 and causing the rainwater to be in an intermittent state during the drainage process, resulting in the inability to continuously maintain the siphon effect. And through the conical diversion cover 10, the converged rainwater can be dispersed outward to guide the rainwater. Among them, by using the auxiliary brush plate 904 to be rotatably arranged, the impurities on the surface of the conical diversion cover 10 can be cleaned during the rotation of the auxiliary brush plate 904 to avoid impurity accumulation to ensure the smoothness of the rainwater collection process. Among them, the air below can be guided upward to the docking channel 3054 through the series of through holes 902.

[0031] In this embodiment, the collection assembly 3 includes a fixed cover 301. A docking seat 303 is provided at the lower end of the fixed cover 301. The docking seat 303 is installed inside the docking groove 101. A number of partition plates 302 are provided inside the fixed cover 301. A converging groove 304 is provided at the center of the lower side of the fixed cover 301.

[0032] During specific installation, a rotating rod 305 is rotatably installed at the center on the upper side of the fixed cover 301. A docking channel 3054 is formed inside the rotating rod 305, and an exhaust hole 3053 is formed on the upper side of the docking channel 3054. A threaded seat 3052 is arranged at the bottom of the rotating rod 305, and a threaded hole 903 is arranged at the upper end of the rotating seat 9. The threaded hole 903 is rotatably connected to the threaded seat 3052.

[0033] Among them, several stress plates 3051 are arranged on the shaft body of the rotating rod 305. The stress plates 3051 are located inside the converging groove 304, and a spiral plate 3055 is arranged on the inner wall of the docking channel 3054.

[0034] By arranging the fixed cover 301 at the ground level, rainwater can enter the inside of the fixed cover 301. Among them, several partition plates 302 can rectify the rainwater in advance to avoid the phenomenon of collision during the entry of rainwater. And the rainwater will fall at the converging groove 304. During the falling process, the rotating rod 305 is rotatably arranged, so that the rainwater will impact several stress plates 3051, making the rotation speed of the rotating rod 305 change with the rainfall. Among them, the rotation of the rotating seat 9 can be ensured through the rotational connection between the threaded hole 903 and the threaded seat 3052 to ensure the cleaning of the auxiliary brush plate 904. Through the shielding cover 7 and the conical diversion cover 10, the air at the docking cylinder 4021 can be concentrated below the collection cover 901. As the rotating rod 305 rotates, the spiral plate 3055 arranged on the inner wall of the docking channel 3054 also rotates. Through the arrangement of the stress plates 3051, the rotating rod 305 will only rotate to one side when the rainwater falls, so that the gas below the collection cover 901 is discharged upward under the guidance of the spiral plate 3055 and discharged from the exhaust hole 3053, thereby improving the gas discharge efficiency and avoiding interference with the subsequent siphon drainage effect due to the inability to discharge the internal gas in time.

[0035] The working principle of this underground rainwater seepage discharge and collection device: During use, first, rainwater will enter the inside of the fixed cover 301. Among them, several partition plates 302 can rectify the rainwater in advance. Subsequently, the rainwater will fall from the converging groove 304. During the falling process, the rotating rod 305 is rotatably arranged, so that the rainwater will impact several stress plates 3051, making the rotating rod 305 rotate. Subsequently, through the conical diversion cover 10, the converged rainwater can be dispersed outward. And through the cooperation of the falling port 6 and the shielding cover 7, the rainwater will first fall to the outside of the water storage tank 102, and the internal water level of the water storage tank 102 will be adjusted with the change of the rainfall, so that the rainwater is discharged from the discharge assembly 4. As the rain gradually increases, the floating disk 402 can adapt to the current water level of the rainwater in the water storage tank 102, so that the rainwater can continuously enter the movable column 401 to ensure the stability of the water inflow during the subsequent siphon process. Several stirring shafts 4061 are movable to stir the rainwater that has just entered the movable column 401. At this time, the rotating rod 305 rotates, so that the spiral plate 3055 provided on the inner wall of the docking channel 3054 also rotates. Thus, under the guidance of the spiral plate 3055, the gas below the collection hood 901 is discharged upward and discharged from the exhaust hole 3053, which can reduce the air inside the rainwater to ensure that when the subsequent rainwater enters the downcomer 202 and the delivery pipe 2, the siphon phenomenon of the rainwater is realized through the height difference between the downcomer 202 and the delivery pipe 2, thereby accelerating the drainage effect.

[0036] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
