[0026] The utility model provides a rainwater collection and drainage device.
[0027] See also Figure 1 and 2In one embodiment of the utility model, the rainwater collection and drainage device 100 includes a drainage device 100, which is installed on a curb 120; wherein the municipal road 110 includes a curb 120, and a cavity 130 is provided inside the curb 120; the drainage device 100 includes a through-hole portion 1, and the cavity 130 is connected to the outside world through the through-hole portion 1; a filter plate assembly 2 and a rotating body 3 are provided inside the through-hole portion 1, and the rotating body 3 is rotatably connected to the drainage device 100, and the rotating body 3 can rotate under the drive of rainwater, and a gap is left between the rotating body 3 and the inner side wall of the through-hole portion 1; one end of the filter plate assembly 2 is connected to the rotating body 3, and the other end of the filter plate assembly 2 is connected to the inner side wall of the through-hole portion 1; the filter plate assembly 2 includes a plurality of filter plate members 21 arranged along a linear array, and a channel for rainwater to pass is provided between adjacent filter plate members 21. With such arrangement, when it rains, rainwater can flow into the cavity 130 through the channels between adjacent filter plates 21, thus draining the rainwater. When impurities such as garbage or leaves are mixed in the rainwater, some of the impurities can flow directly into the cavity 130 through the channels along with the rainwater; some of the impurities rush toward the rotating body 3 under the push of the rainwater, and the rotating body 3 also rotates under the push of the rainwater, thereby rolling the impurities into the cavity 130 through the gap between the rotating body 3 and the inner side wall of the through hole 1; in this way, the possibility of impurities accumulating on the side of the drainage device 100 facing away from the cavity 130 can be reduced, thereby reducing the risk of the rainwater collection and drainage device 100 being blocked.
[0028] Specifically, see Figure 2 and Figure 3 The drainage device 100 includes a support frame 4, which is connected to the inner wall of the through hole portion 1; the support frame 4 includes a top beam 41 and columns 42 located at both ends of the top beam 41, and both ends of the rotating body 3 are rotatably connected to the columns 42 respectively; the upper end of the filter plate assembly 2 is installed on the top beam 41, and the lower end of the filter plate assembly 2 is connected to the rotating body 3. By providing the support frame 4, on the one hand, it is convenient to install the drainage device 100 to the through hole portion 1, and on the other hand, it is also convenient to install the filter plate assembly 2 and the rotating body 3.
[0029] Specifically, a plurality of filter plate members 21 are arranged in an array along the length direction of the top beam 41; the filter plate member 21 includes a fixed plate 22 and a movable plate 23, the first end of the fixed plate 22 and the first end of the movable plate 23 abut against each other; the fixed plate 22 is fixedly connected to the column 42, the second end of the fixed plate 22 is connected to the rotating body 3; the second end of the movable plate 23 is rotatably connected to the top beam 41. It can be understood that in this embodiment, the filter plate assembly 2 is arranged in an array along the length direction of the top beam 41, and the first end of the fixed plate 22 and the first end of the movable plate 23 abut against each other, the second end of the fixed plate 22 is connected to the rotating body 3, and the second end of the movable plate 23 is rotatably connected to the top beam 41, that is, the rotating body 3 is arranged near the bottom wall of the through hole portion 1; such an arrangement increases the contact area between the impurities and the rotating body 3, which is conducive to increasing the probability that the impurities can be rolled into the cavity 130. Furthermore, since the first end of the movable plate 23 abuts against the first end of the fixed plate 22, and the second end of the movable plate 23 is rotatably connected to the top beam 41, when the water level of the municipal road 110 is higher than the rotating body 3, rainwater can rush the first end of the movable plate 23 toward the cavity 130, and at the same time, the second end of the movable plate 23 rotates around the top beam 41 to separate the first end of the movable plate 23 and the first end of the fixed plate 22, thereby increasing the passing space of rainwater, and the rainwater drives impurities to flow into the cavity 130; such a configuration further reduces the risk of the drainage device 100 being blocked. In one embodiment, the movable plate 23 can be rotatably connected to the top beam 41 through the rotating shaft 6; specifically, the movable plate 23 can be rotatably mounted on the rotating shaft 6, and the rotating shaft 6 is fixedly mounted on the top beam 41; in another embodiment, the movable plate 23 can be fixedly mounted on the rotating shaft 6, and the rotating shaft 6 is rotatably connected to the top beam 41; there is no limitation to this, as long as the movable plate 23 can be rotatably connected to the top beam 41.
[0030] Furthermore, the top beam 41 is provided with a limiter 7, which is used to limit the rotation angle of the movable plate 23. When the separation degree of the movable plate 23 and the fixed plate 22 is too large, a large gap is easily formed at the rainwater collection and drainage device 100, and the gap is dangerous to pedestrians or small animals, etc., so it is necessary to limit the separation degree of the movable plate 23 and the fixed plate 22. The limiter 7 is provided on the top beam 41, which can play a role in limiting the rotation angle of the movable plate 23, and further limit the separation degree of the movable plate 23 and the fixed plate 22.
[0031] In some embodiments, the filter plate assembly 2 includes a first rod 24, the first rod 24 passes through the fixing plate 22, and both ends of the first rod 24 are respectively fixedly connected to the columns 42. That is, the plurality of fixing plates 22 are fixed by the first rod 24, and are easily installed with the support frame 4.
[0032] In some embodiments, the drainage device 100 includes a second rod 5, both ends of which are connected to the column 42, and the second end of the fixed plate 22 is rotatably connected to the rotating body 3 through the second rod 5. Connecting the fixed plate 22 and the rotating body 3 through the second rod 5 is conducive to reducing the volume of the connecting portion of the rotating body 3 and the fixed plate 22, thereby reducing the interception effect on rainwater.
[0033] Further, in some embodiments, see Figure 4 , the rotating body 3 is located between two adjacent fixed plates 22. It can be understood that by providing multiple rotating bodies 3 and making each rotating body 3 located between two adjacent fixed plates 22, the rotating body 3 can correspond to the position of the channel through which rainwater passes. In this way, when rainwater passes through the channel, the flow rate of rainwater becomes faster, providing a driving force to the rotating body 3, pushing the rotating body 3 to rotate better, thereby improving the efficiency of impurities being drawn into the cavity 130.
[0034] In some embodiments, see Figure 2 The cavity 130 includes a drain port 140, which is located at the bottom of the cavity 130; the rainwater collection and drainage device 100 also includes a filter screen 8, which is located between the drain port 140 and the through hole 1. It can be understood that the cavity 130 has a certain water collection and buffering effect. By arranging the filter screen 8 between the drain port 140 and the through hole 1, impurities flowing into the cavity 130 can be filtered to prevent the drain port 140 from being blocked.
[0035] Furthermore, the rainwater collection and drainage device 100 also includes a garbage chamber 9, which is arranged at one side of the cavity 130; the garbage chamber 9 is used to receive impurities blocked by the filter screen 8; the garbage chamber 9 is provided with an opening portion, and the garbage chamber 9 is connected to the outside through the opening portion; the opening portion is provided with a protective cover 91. In this way, the impurities blocked by the filter screen 8 can be introduced into the garbage chamber 9 to prevent the impurities from accumulating too much on the filter screen 8; and the garbage chamber 9 is arranged at one side of the cavity 130, and the garbage chamber 9 is provided with an opening portion, and the garbage chamber 9 is connected to the outside through the opening portion, so that the garbage in the garbage chamber 9 can be easily removed. The provision of the protective cover 91 can prevent foreign objects from falling into the garbage chamber 9, and can also prevent garbage from being scattered everywhere under the influence of wind or other factors.
[0036] In one embodiment, the filter screen plate 8 may be arranged to be inclined, with the inclined lower end of the filter screen plate 8 facing the garbage chamber 9 , so that the impurities blocked by the filter screen plate 8 can be more easily introduced into the garbage chamber 9 .
[0037] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
