Description

Technical Field

[0001] The utility model relates to the technical field of drainage structures, in particular to a sunken green belt drainage structure. Background Art

[0002] For the sunken green belt, the rainwater it receives is mostly road surface water and direct rainwater dripping. The rainwater on the road surface enters the green belt through the holes on the curb and is then discharged under the infiltration effect of the greening.

[0003] A sunken green belt is disclosed in a Chinese utility model patent with publication number CN210507005U, including a green belt body excavated below a road surface, wherein both sides of the upper end of the green belt body are provided with lanes paved at a certain angle toward the green belt body; the vertical section of the green belt body is a layered structure, the bottom layer of the green belt body is composed of a waterproof base layer paved with waterproof coiled material, the upper surface of the waterproof base layer is paved with a permeable gravel layer, a perforated drainage pipe is buried in the permeable gravel layer, and the perforated drainage pipe is connected to the rainwater drainage channel.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device assists in draining the road surface through multiple external water inlet holes opened on the outer surface of the curbstone, thereby reducing the probability of water accumulation on the road surface during rainy weather. However, in actual use, since most of the green belts are planted with plants, impurities such as fallen leaves of plants are easily accumulated near the external water inlet holes. When it is rainy near the road surface, the fallen leaves and other impurities are easily blocked by the rain, thereby causing the auxiliary drainage function to be almost lost, which easily causes the road surface to be continuously in a state of water accumulation. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a sunken green belt drainage structure.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a sunken green belt drainage structure, including a driveway and a green belt main body connected to the driveway, curbstones are arranged on the two opposite side walls of the green belt main body, multiple water inlets are arranged on the side walls where the two curbstones are close to each other, multiple water outlets are arranged on the side walls where the two curbstones are close to each other, upper drainage channels and lower drainage channels that are interconnected are arranged in the curbstone, multiple water inlets are interconnected with the upper drainage channel, multiple water outlets are interconnected with the lower drainage channel, a connecting groove that is interconnected with multiple water inlets is opened on the side wall of the curbstone, and a filter screen for blocking impurities such as fallen leaves is arranged in the connecting groove.

[0007] By adopting the above technical solution, when it is rainy near the green belt, water is easily accumulated on the upper surface of the lane. When the height of the water flow is flush with the water inlet, the water flow moves into the water inlet and finally enters the lower drainage channel through the upper drainage channel and is discharged, thereby reducing the drainage pressure of the road surface. In this process, the filter screen blocks impurities in the rainwater, thereby reducing the probability of clogging the water inlet.

[0008] Furthermore, a receiving groove is provided on the upper surface of the curbstone, a rotation groove is provided at the lower end of the inner wall of the receiving groove, and a cleaning component for cleaning the filter is provided on the curbstone.

[0009] Furthermore, the cleaning assembly includes a rotating rod rotatably arranged on the inner wall of the rotating groove, a baffle fixed on the side wall of the rotating rod, a first magnet block arranged on the bottom surface of the baffle, and a second magnet block embedded in the bottom wall of the rotating groove, and the first magnet block and the second magnet block are attracted to each other.

[0010] By adopting the above technical solution, when it is rainy near the green belt, rainwater contacts the receiving tank, and water gradually accumulates in the receiving tank, so that the force acting on the baffle gradually increases. Subsequently, when the force acting on the baffle is greater than the suction force of the first magnet block and the second magnet block, the baffle rotates under the action of the water flow, and the water flow in the receiving tank moves to the outside of the curb through the rotating groove, so that the water flow cleans the filter, thereby reducing the probability of a large amount of impurities adsorbed on the filter.

[0011] Furthermore, an L-shaped plate for diverting rainwater is provided on the side wall of the curbstone.

[0012] By adopting the above technical solution, when the water flow moves outside the curb, the L-shaped plate guides the water flow, thereby increasing the probability of the water flow directly impacting the filter, thereby improving the cleaning effect of the water flow.

[0013] Furthermore, a partition net for closing the accommodating groove is arranged on the inner wall of the accommodating groove.

[0014] By adopting the above technical solution, the probability of impurities moving into the containing tank is reduced, thereby improving the stability of the device.

[0015] Furthermore, the cross section of the partition net is in an arc shape, and the degree of the cross section of the partition net is 40 degrees.

[0016] By adopting the above technical solution, the probability of impurities such as stones being separated from the partition net under the action of the arc surface of the partition net when they come into contact with each other is increased, thereby further reducing the probability of impurities entering the partition net, thereby improving the user experience of the staff.

[0017] Furthermore, a slide groove is provided on the inner wall of the accommodating groove, a slider is slidably arranged in the slide groove, and the slider is fixed to the bottom surface of the partition net.

[0018] Furthermore, a support spring is provided on the bottom surface of the sliding block, and the other end of the support spring is fixed to the inner bottom wall of the sliding groove.

[0019] By adopting the above technical solution, when the partition net is not subjected to external force, the slider is always pressed against the inner top wall of the slide groove under the action of the support spring, so that the partition net remains stable and the lowest point of the partition net is flush with the upper surface of the curb, thereby increasing the probability of impurities and the partition net being separated from each other. In addition, when passers-by step on the partition net, the partition net moves downward under the action of external force, thereby reducing the probability of the partition net being damaged, which is conducive to extending the service life of the partition net.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when it rains near the green belt, water is easily accumulated on the upper surface of the lane. When the height of the water flow is flush with the water inlet, the water flow moves into the water inlet and eventually enters the lower drainage channel through the upper drainage channel and is discharged, thereby reducing the drainage pressure of the road surface. In this process, the filter screen blocks impurities in the rainwater, thereby reducing the probability of clogging the water inlet;

[0022] 2. In the present application, when it is raining near the green belt, rainwater contacts the receiving tank, and water gradually accumulates in the receiving tank, so that the force acting on the baffle gradually increases. Subsequently, when the force acting on the baffle is greater than the suction force of the first magnet block and the second magnet block, the baffle rotates under the action of the water flow, and the water flow in the receiving tank moves to the outside of the curb through the rotating groove, so that the water flow cleans the filter, thereby reducing the probability of a large amount of impurities adsorbed on the filter;

[0023] 3. In the present application, when the partition net is not subjected to external force, the slider is always pressed against the inner top wall of the slide groove under the action of the support spring, so that the partition net remains stable and the lowest point of the partition net is flush with the upper surface of the curb, thereby increasing the probability of impurities and the partition net being separated from each other. In addition, when passers-by step on the partition net, the partition net moves downward under the action of external force, thereby reducing the probability of damage to the partition net, which is conducive to extending the service life of the partition net.

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0032] like Figure 1-6 As shown, the embodiment of the present application discloses a sunken green belt drainage structure, including a lane 1, a green belt body 11, a curb 2, an upper drainage channel 31, a lower drainage channel 4, a filter 5, a cleaning assembly 6, an L-shaped plate 7, a separator 71, a slider 81 and a support spring 9. The green belt body 11 is connected to the lane 1, and the curb 2 is provided with two side walls that are respectively opposite to the green belt body 11 and are connected to each other. A plurality of water inlets 21 are provided on the side walls of the two curbs 2 that are close to each other, and a plurality of water outlets 3 are provided on the side walls of the two curbs 2 that are close to each other, and an upper drainage channel 31 and a lower drainage channel 4 that are connected to each other are provided in the curb 2. The plurality of water inlets 21 are all connected to the upper drainage channel 31, and the plurality of water outlets 3 are all connected to the lower drainage channel 4. A connecting groove 41 that is connected to the plurality of water inlets 21 is provided on the side wall of the curb 2, and the filter 5 is provided in the connecting groove 41 to block impurities such as fallen leaves.

[0033] A receiving groove 51 is provided on the upper surface of the curb 2, and a rotating groove 52 is provided at the lower end of the inner wall of the receiving groove 51. A cleaning assembly 6 is arranged on the curb 2 for cleaning the filter 5. The cleaning assembly 6 comprises a rotating rod 61, a baffle 62, a first magnet block 63 and a second magnet block 64. The rotating rod 61 is a round rod-shaped structure, and the rotating rod 61 is rotatably arranged on the inner wall of the rotating groove 52. The baffle 62 is a plate-shaped structure, and the baffle 62 is fixed on the side wall of the rotating rod 61. The first magnet block 63 is a block-shaped structure, and the first magnet block 63 is arranged on the bottom surface of the baffle 62. The second magnet block 64 is a block-shaped structure, and the second magnet block 64 is embedded in the inner bottom wall of the rotating groove 52, and the first magnet block 63 and the second magnet block 64 are mutually adsorbed.

[0034] When it is rainy near the green belt, rainwater contacts the receiving groove 51, and water gradually accumulates in the receiving groove 51, thereby gradually increasing the force on the baffle 62. Subsequently, when the force on the baffle 62 is greater than the suction force of the first magnet block 63 and the second magnet block 64, the baffle 62 rotates under the action of the water flow, and the water flow in the receiving groove 51 moves to the outside of the curb 2 through the rotating groove 52, so that the water flow cleans the filter 5, thereby reducing the probability of a large amount of impurities adsorbed on the filter 5.

[0035] The L-shaped plate 7 is a plate-like structure with an L-shaped cross section, and is arranged on the side wall of the curb 2 to guide rainwater. When the water flow moves outside the curb 2, the L-shaped plate 7 guides the water flow, thereby increasing the probability of the water flow directly impacting the filter 5, thereby improving the cleaning effect of the water flow.

[0036] The partition net 71 is disposed on the inner wall of the receiving groove 51 to seal the receiving groove 51. The partition net 71 reduces the probability of impurities moving into the receiving groove 51, thereby improving the stability of the device.

[0037] In order to improve the user experience of the staff, the cross section of the partition 71 is arc-shaped, and the angle of the cross section of the partition 71 is 40 degrees. This arrangement increases the probability that impurities such as stones will be separated from the partition 71 under the action of the arc surface of the partition 71 when they come into contact with each other, thereby further reducing the probability of impurities entering the partition 71, thereby improving the user experience of the staff.

[0038] A slide groove 8 is provided on the inner wall of the receiving groove 51. The slider 81 is a block structure. The slider 81 is slidably arranged in the slide groove 8, and the slider 81 is fixed to the bottom surface of the partition 71. One end of the support spring 9 is arranged on the bottom surface of the slider 81, and the other end of the support spring 9 is fixed to the inner bottom wall of the slide groove 8.

[0039] When the partition net 71 is not subjected to external force, the slider 81 is always pressed against the inner top wall of the slide groove 8 under the action of the support spring 9, so that the partition net 71 remains stable and the lowest point of the partition net 71 is flush with the upper surface of the curb 2, thereby increasing the probability of separation of impurities from the partition net 71. In addition, when a passerby steps on the partition net 71, the partition net 71 moves downward under the action of external force, thereby reducing the probability of damage to the partition net 71, which is conducive to extending the service life of the partition net 71.

[0040] The principle of use of a sunken green belt drainage structure in this embodiment is: when it is rainy near the green belt, water is easily accumulated on the upper surface of the lane 1. When the height of the water flow is flush with the water inlet 21, the water flow moves into the water inlet 21 and finally enters the lower drainage channel 4 through the upper drainage channel 31 to be discharged, thereby reducing the drainage pressure of the road surface. In this process, the filter 5 blocks impurities in the rainwater, thereby reducing the probability of clogging the water inlet 21.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
