Embodiment
[0033] The following is further illustrated with specific embodiments. Referring to Figures 1 - 5 As shown, the present utility model is a stepped and gradually changing rainwater regulation device, including a water storage tank 1. The water storage tank 1 includes a bottom tank 14 and a top plate 15. The bottom tank 14 and the top plate 15 are fixedly connected together by bolts. The top wall of the top plate 15 is concave. A plurality of water inlets 151 are opened on the top plate 15. The water inlets 151 can play a role in allowing rainwater to flow into the water storage tank 1. Above the top plate 15, a dense steel wire mesh layer 16, a cobblestone layer 17 and a sandy soil infiltration layer 18 are successively covered. The dense steel wire mesh layer 16, the cobblestone layer 17 and the sandy soil infiltration layer 18 can all play a role in filtering water. At the same time, the dense steel wire mesh layer 16 can play a role in supporting the cobblestone layer 17 and the sandy soil infiltration layer 18.
[0034] The water storage tank 1 is used to be embedded in the green belt on one side of the road. A water inlet pipe 11 is connected and arranged at the side wall position of the water storage tank 1 near the top. The water inlet pipe 11 is connected to the drainage grille 21 at the curbstone 2 of the road. A purified water pipe 12 is connected and installed at the bottom of the water storage tank 1.
[0035] Among them, the central groove 3 is located at the center of the water storage tank 1. A plurality of drain holes 32 are provided on the bottom wall and the surrounding side walls of the central groove 3. A plurality of annular grooves 31 are provided. The annular grooves 31 are slidably inserted into each other in pairs and are arranged in a telescopic cylinder shape. The innermost annular groove 31 is slidably inserted into the central groove 3. The outer wall of the outermost annular groove 31 is fixedly connected to the inner wall of the water storage tank 1. A plurality of drain holes 32 are also provided on the side wall of the annular groove 31. The bottom wall of the annular groove 31 is closed. In this way, a conical water guiding function can be formed to guide rainwater to the position of the central groove 3 and finally to the bottom of the water storage tank 1.
[0036] Refer to Figure 1 As shown, the main drain pipe 13 is connected to the side wall of the water storage tank 1 and is located near the top wall of the outermost annular groove 31 and is used to connect to the sewer pipe. The main drain pipe 13 can play a role in quickly draining water when the rainfall is large.
[0037] Refer to Figure 1 and Figure 3 As shown, the limiting member 4 is arranged between adjacent annular grooves 31 and between the central groove 3 and the annular groove 31 and is used to limit their sliding separation from each other. Specifically, the limiting member 4 includes a limiting block 42 and a limiting groove 41. The limiting block 42 and the limiting groove 41 are respectively arranged on the side walls between adjacent annular grooves 31. The limiting groove 41 is vertically opened and the two ends of the limiting groove 41 are not penetrated. The limiting block 42 is slidably connected in the limiting groove 41. The shape of the limiting groove 41 can be square or dovetail, etc.
[0038] As an alternative embodiment, a water guiding hopper 6 is installed below the central groove 3 in the water storage tank 1. The water guiding hopper 6 is fixedly connected to the inner wall of the water storage tank 1. The water guiding hopper 6 is in a funnel shape. A filter plate 61 is arranged at the lower opening position of the water guiding hopper 6. The filter plate 61 can play a role in filtering rainwater, and the water guiding hopper 6 can play a role in guiding rainwater.
[0039] Refer to Figure 1 and Figure 4 As shown, a first overflow plate 7 and a second overflow plate 71 are respectively vertically and fixedly installed on the inner bottom wall of the water storage tank 1. The first overflow plate 7 is higher than the second overflow plate 71. Both the first overflow plate 7 and the second overflow plate 71 are in a circular shape. The first overflow plate 7 is located inside the second overflow plate 71 and is spaced apart from each other. The clean water pipe 12 is connected to the bottom side wall position of the water storage tank 1. At the same time, the lower opening of the water guiding hopper 6 is located directly above the first overflow plate 7. The first overflow plate 7 and the second overflow plate 71 can play a role in precipitating impurities in the water.
[0040] Refer to Figure 4As shown, in order to achieve a better water filtration effect, a water filter plate 72 is also installed on the inner bottom wall of the water storage tank 1. The water filter plate 72 is arranged in a loop shape, located outside the second overflow plate 71 and spaced from the second overflow plate 71. The water filter plate 72 is higher than the first overflow plate 7. By setting the first overflow plate 7, the second overflow plate 71 and the water filter plate 72, the filtration and sedimentation functions of the water storage tank 1 are improved.
[0041] Referring to Figure 4 and Figure 5 As shown, as an alternative embodiment, a water baffle 152 is hingedly installed at each water inlet 151. The hinge axis of the water baffle 152 is horizontally arranged. The water baffle 152 closes the water inlet 151. A foam block 153 is fixedly arranged at the top wall position on the side of the water baffle 152 away from the hinge axis. The foam block 153 protrudes from the water baffle. After the foam block 153 is submerged by rainwater, due to the buoyancy effect, the foam block 153 will drive the water baffle 152 to rotate by a certain angle, and there will be a gap between the water baffle 152 and the water inlet 151, and rainwater will enter the water storage tank 1 from the gap to play an automatic drainage role.
[0042] Referring to Figure 1 and Figure 4 As shown, slag discharge pipes 8 are connected and arranged at the side wall of the water guide hopper 6 near the hopper mouth, below the first overflow plate 7 of the water storage tank 1, between the first overflow plate 7 and the second overflow plate 71 of the water storage tank 1, and between the second overflow plate 71 and the filter plate 61 of the water storage tank 1. An electromagnetic water valve 81 is installed on the slag discharge pipe 8. By regulating the electromagnetic water valve 81, the slag discharge function can be achieved to prevent impurities from accumulating and blocking, affecting the subsequent purification of rainwater.
[0043] Referring to Figure 1 and Figure 4 As shown, as an alternative embodiment, in order to facilitate driving the central groove 3 to rise or fall and fixing it to the moved position, the driving member 5 is a winch 51. The winch 51 is fixedly installed on the top wall of the top plate 15. A protective cover 53 is installed over the winch 51. The motor of the winch 51 is a stepping motor with a self-locking function to facilitate locking and limiting after the motor stops rotating. The steel wire rope 52 of the winch 51 passes through the top plate 15 and is welded at the central position of the central groove 3. Starting the winch 51 to wind the steel wire rope 52 can lift and lower the central groove 3.
[0044] The working process of this embodiment is as follows: when the rainfall is small, the drainage grille 21 at the curbstone 2 guides the rainwater into the water storage tank 1 through the water inlet pipe 11 and the water inlet 151. During this period, the rainwater is filtered multiple times by the drainage holes 32 of the multiple spiral grooves 31, and then discharged into the lower part of the water storage tank 1 through the drainage holes 32 of the central groove 3. After precipitation and purification by the first overflow plate 7, the second overflow plate 71 and the water filter plate 72, it finally flows into the purification pool through the purified water pipe 12, realizing the filtration and recycling of rainwater; when the rainfall is too large, the taper of the multiple spiral grooves 31 and the central groove 3 can be adjusted by the winch 51, and the multiple spiral grooves 31 and the central groove 3 are adjusted to an inverted cone shape, so as to discharge a large amount of rainwater into the sewer through the main drainage pipe 13. Finally, the staged and hierarchical control and recycling of rainwater are realized, and the regulation ability of rainwater and the drainage demand are improved.
