Description

Technical Field

[0001] This utility model relates to the field of rainwater treatment technology, specifically to a biomimetic aquatic plant integrated initial rainwater purification device. Background Technology

[0002] During the rain, rainwater washes over rooftops, roads, etc., carrying pollutants into the pond and causing pollution. After the initial rainwater enters the pond, it first enters the biofilm reactor area, where most of the pollutants are reduced after aeration, stirring, and biofilm interception. Next, it enters the biomimetic aquatic plant purification and sedimentation area, where pollutants or organisms are adsorbed, intercepted, and settled, improving the water transparency.

[0003] Currently, when treating initial rainwater, bionic aquatic plants are scattered in the pond, which has problems such as irregular arrangement, easy tangling and accumulation, and poor fit with the inlet and outlet, which reduces the purification effect. To address these issues, we propose an integrated bionic aquatic plant initial rainwater purification device. Utility Model Content

[0004] The purpose of this invention is to provide a biomimetic aquatic plant integrated early rainwater purification device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a biomimetic aquatic plant integrated initial rainwater purification device, comprising a cylinder, wherein a supporting grid is provided at the upper end of the cylinder, and a biomimetic aquatic plant filler unit is arranged between the supporting grid and the bottom side inside the cylinder.

[0006] The biomimetic aquatic plant filler unit includes biomimetic aquatic plant filaments. One end of the biomimetic aquatic plant filaments is fixedly connected to a connector, and the other end is fixedly connected to a fixing rod. A mounting circular plate is fixedly connected to the bottom of the fixing rod, and a counterweight is fixedly connected to the bottom of the mounting circular plate. A sliding plate is slidably connected to the outer wall of the fixing rod, and a spring is sleeved between the sliding plate and the top of the fixing rod. Several sets of concentric rings of the biomimetic aquatic plant filaments are arranged, with the inner and outer rings staggered.

[0007] As a further embodiment of this utility model: a positioning hole is provided in a concentric ring on the bottom side of the inner side of the cylinder, the counterweight is inserted into the positioning hole, and a limit hole is provided in the circumferential direction on the outer side of the positioning hole.

[0008] As a further embodiment of this utility model: support grooves are arranged in the circumferential direction on the inner wall of the upper end of the cylinder, and the supporting grid is supported on the support grooves.

[0009] As a further embodiment of this utility model: the upper end of the cylinder is bolted to a cylinder cover, and the bottom center of the cylinder cover abuts against the center of the supporting grid through a rod.

[0010] As a further embodiment of this utility model: both sides of the upper end of the connector are movably connected with snap-fit ​​plates, the supporting grid is arranged in a concentric ring direction with through holes, and both ends of the through holes are provided with snap-fit ​​grooves, the connector passes through the through holes and the snap-fit ​​plates are snapped into the snap-fit ​​grooves.

[0011] As a further embodiment of this utility model: two limiting holes are arranged in the circumferential direction at the edge of the mounting plate, and the number of the two limiting holes is the same as that of the first limiting hole.

[0012] As a further embodiment of this utility model: both ends of the sliding plate are fixedly connected with limiting rods, and the limiting rods pass through the second limiting hole and extend into the first limiting hole.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0026] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see the appendix Figure 1 -Appendix Figure 6 This utility model discloses a biomimetic aquatic plant integrated initial rainwater purification device, including a cylinder 1, a supporting grid 4 at the upper end of the cylinder 1, and a biomimetic aquatic plant filler unit 6 arranged between the supporting grid 4 and the bottom inside the cylinder 1.

[0028] In Example 1, the biomimetic aquatic plant filler unit 6 includes biomimetic aquatic plant filaments 61. One end of the biomimetic aquatic plant filaments 61 is fixedly connected to a connector 62, and the other end of the biomimetic aquatic plant filaments 61 is fixedly connected to a fixing rod 63. The bottom of the fixing rod 63 is fixedly connected to a mounting circular plate 64, and the bottom of the mounting circular plate 64 is fixedly connected to a counterweight block 66. A sliding plate 67 is slidably connected to the outer wall of the fixing rod 63, and a spring 68 is sleeved between the sliding plate 67 and the top of the fixing rod 63. Several sets of concentric rings of the biomimetic aquatic plant filaments 61 are arranged in an alternating manner.

[0029] Specifically, the bottom of the inner side of the cylinder 1 is provided with a positioning hole 12 in a concentric ring. The counterweight 66 is inserted into the positioning hole 12. The outer side of the positioning hole 12 is provided with a first limiting hole 13 arranged in the circumferential direction. The edge of the mounting plate 64 is provided with a second limiting hole 65 arranged in the circumferential direction. The number of second limiting holes 65 is the same as that of first limiting holes 13. Both ends of the sliding plate 67 are fixedly connected with limiting rods 69. The limiting rods 69 pass through the second limiting hole 65 and extend into the first limiting hole 13 at the bottom.

[0030] In this embodiment, the bionic aquatic plant filament 61 is provided with a detachable structure, which can replace the bionic aquatic plant filament 61 that has been clogged or aged over a long period of use. That is, flip the snap-fit ​​plates 621 on both sides to disengage them from the snap-fit ​​groove 42, so that the bionic aquatic plant filament 61 can be detached from the supporting grid 4. Then, pull the wrenches at both ends of the sliding plate 67 to squeeze the spring 68, so that the limiting rod 69 disengages from the limiting hole 13, and the bionic aquatic plant filament 61 can be removed for replacement.

[0031] Specifically, a support groove 14 is arranged in the circumferential direction on the inner wall of the upper end of the cylinder 1, and the support grid 4 is supported on the support groove 14. The upper end of the cylinder 1 is bolted to the cylinder cover 2, and the bottom side of the cylinder cover 2 abuts against the middle of the support grid 4 through a rod.

[0032] In this embodiment, the supporting grid 4 is detachably installed in the support groove 14, and the supporting grid 4 is abutted by the rod on the cylindrical cover 2, so that the supporting grid 4 is not easily shaken with the water flow and affects the purification effect of the bionic aquatic plant filaments 61.

[0033] Specifically, the upper ends of the connector 62 are movably connected to the snap-fit ​​plates 621 on both sides. The support grid 4 is arranged in a concentric ring direction with through holes 41. Both ends of the through holes 41 are provided with snap-fit ​​grooves 42. The connector 62 passes through the through holes 41 and the snap-fit ​​plates 621 are snapped into the snap-fit ​​grooves 42.

[0034] Specifically, a fixed cone 3 is fixedly connected to the bottom center of the cylinder 1, and an arc-shaped mounting groove 11 is arranged on the outer surface of the cylinder 1. Filter components 5 are provided at the upper and lower ends of the arc-shaped mounting groove 11 by screws.

[0035] In this embodiment, the fixed cone 3 fixes the cylinder 1 in the pond, and the filter assembly 5 can further filter the water flow after the biofilm reactor.

[0036] Working principle:

[0037] First, the device is fixed in the pond using the fixing cone 3, arranged in rows and staggered from the inlet to the outlet. During purification, it is further filtered by the filter assembly 5. When the water flows to the bionic aquatic plant fibers 61 inside, the staggered arrangement of the inside and outside allows the water to come into contact with more bionic aquatic plant fibers, extending the water purification path length and residence time. When it is necessary to replace the clogged or aged bionic aquatic plant fibers, the user pulls out the cylinder 1, first removes the cylinder cover 2, and then flips the snap plate 621 on the support grid 4 to disengage it from the snap groove 42, so that the bionic aquatic plant fibers 61 can be detached from the support grid 4. Then, the user pulls the wrenches at both ends of the sliding plate 67 to squeeze the spring 68, so that the limiting rod 69 disengages from the limiting hole 13, and the bionic aquatic plant fibers 61 can be removed for replacement. At this point, the entire workflow is completed.
