Technical Field
[0001] This utility model relates to the field of municipal engineering technology, and more specifically, to a high-efficiency rainwater collection and filtration device for urban roads. Background Technology
[0002] With the acceleration of urbanization, the area of paved surfaces in cities is constantly increasing, leading to a decline in the natural infiltration capacity of rainwater and exacerbating the risk of urban flooding. Rainwater harvesting and utilization are effective means to alleviate urban flooding and achieve water resource recycling.
[0003] Due to the complex composition of pollutants in urban road rainwater, the filter screens or pores of traditional filtration devices are easily clogged by silt and debris, leading to a significant decrease in rainwater collection rates and even causing rainwater overflow, exacerbating the risk of urban flooding. According to statistics from actual engineering cases, traditional devices require manual disassembly and cleaning every 1-2 weeks on average, which not only consumes a large amount of labor but also requires suspending rainwater collection operations during cleaning, affecting the overall operational efficiency of the device. Therefore, we propose a high-efficiency rainwater collection and filtration device for urban roads. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an efficient rainwater collection and filtration device for urban roads, so as to solve the technical problem that the current filtration structure is prone to clogging and affects the rainwater collection rate.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency rainwater collection and filtration device for urban roads, including a water storage tank, a filter cover for filtering fine particles fixedly installed on the top of the water storage tank, and the filter cover is triangular in shape. A filter baffle for filtering large debris is fixedly installed on the top of the filter cover. A fixing plate flush with the top of the filter cover is fixedly connected between the internal facing surfaces of the filter cover. Several elastic support members are fixedly installed on the top of the fixing plate. An adjusting member penetrating the top of the filter cover is fixedly connected between the tops of each elastic support member. A sealing frame that fits against the outer wall of the adjusting member is fixedly installed on the top of the filter cover. A dredging component that cooperates with the filter holes of the filter cover is fixedly installed at the bottom of the adjusting member.
[0006] The adjusting component includes a base, and a water collection box is fixedly installed on the top of the base. The inner cavity of the water collection box has a first water outlet groove that is flush with the bottom surface on both sides. The same second water outlet groove is provided on the side wall of the sealing frame and below the first water outlet groove.
[0007] This invention utilizes a dynamic combination of a filter cover, an adjusting component, and a cleaning assembly. When rainwater accumulates to a certain weight in the collection box, the compression of the elastic support component drives the adjusting component and the lower cleaning assembly to move downwards, allowing the cleaning block on the cleaning assembly to insert and clean the filter holes of the filter cover. After the rainwater is discharged, it returns to its original position under the action of the elastic support component. This process uses the weight of the rainwater as a power source, achieving fully automatic and periodic self-cleaning, completely preventing the filter holes from being blocked by fine particles, and ensuring the long-term, efficient, and unobstructed operation of the rainwater collection channel even when unattended.
[0008] Preferably, the unblocking component includes several fixed rods of different lengths, and each fixed rod penetrates the wall of the fixed plate. A horizontal plate is fixedly installed at the lower end of each fixed rod, and a fixing strip is fixedly connected between the ends of the horizontal plate. A guide plate that fits against the inner side of the filter cover is fixedly installed between the fixing strips on one side, and several unblocking blocks that are inserted into the filter holes of the filter cover are fixedly installed on the top surface of the guide plate.
[0009] Preferably, each of the elastic supports includes a sleeve, and a first spring is fixedly disposed inside the sleeve. A connecting rod passing through the top of the sleeve and connecting to the base is fixedly disposed at the top of the first spring.
[0010] Preferably, a triangular diverter strip is fixedly provided on the bottom side of the inner cavity of the water collection box, and the two inclined surfaces of the triangular diverter strip are flush with the bottom side of the water collection box.
[0011] Preferably, the opposing surfaces of the sealing frame are provided with a plurality of mounting slots, and a plurality of second springs are fixedly installed inside each mounting slot. The second springs in the same group are fixedly connected with a resistance strip that abuts against the side of the water collection box.
[0012] Preferably, the opposite sides of the water collection box are provided with a number of resistance grooves corresponding to the positions of the resistance bars, and the distance between the water collection box and the resistance grooves is the same as the distance between the water collection box and the second water outlet groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model dynamically combines a filter cover, an adjusting component, and a cleaning assembly. When rainwater accumulates to a certain weight in the collection box, the compression of the elastic support drives the adjusting component and the lower cleaning assembly to move downwards, allowing the cleaning block on the cleaning assembly to insert and clean the filter holes of the filter cover. After the rainwater is discharged, it returns to its original position under the action of the elastic support. This process utilizes the weight of the rainwater as a power source, achieving fully automatic and periodic self-cleaning, completely preventing the filter holes from being blocked by fine particles, and ensuring long-term, efficient, and unobstructed operation of the rainwater collection channel even when unattended.
[0015] 2. This utility model also effectively guides road runoff from different directions through a triangular filter cover structure, preventing water from concentrating and impacting a single area. Secondly, the triangular diversion strips inside the water collection box disperse the water entering the box, smoothly guiding it to the first outlet trough. Furthermore, the combination of resistance strips and resistance grooves between the sealing frame and the water collection box provides motion damping, making the downward movement and resetting process of the adjusting component smoother, buffering the impact of water flow and the rigid collision of mechanical action, thereby improving the service life and stability of the entire device. Moreover, the combination of resistance grooves and resistance strips can extend the alignment time between the first and second outlet troughs, increasing drainage volume to reduce the weight of the adjusting component, further improving the resetting effect of the unblocking components.

[0023] like Figures 1 to 6As shown, this utility model relates to an efficient rainwater collection and filtration device for urban roads, including a water storage tank 1. A filter cover 2 for filtering fine particles is fixedly installed on the top of the water storage tank 1, and the filter cover 2 is triangular in shape. A filter baffle 3 for filtering large debris is fixedly installed on the top of the filter cover 2. A fixing plate 4, flush with the top of the filter cover 2, is fixedly connected between the facing surfaces inside the filter cover 2. Several elastic support members 5 are fixedly installed on the top of the fixing plate 4, and a through-hole is fixedly connected between the tops of each elastic support member 5. The top of the filter cover 2 is fixedly equipped with a sealing frame 7 that fits against the outer wall of the adjusting component 6, and the bottom of the adjusting component 6 is fixedly equipped with a dredging component 8 that cooperates with the filter holes of the filter cover 2. The cooperation between the filter cover 2 and the filter baffle 3 can achieve the effect of graded filtration. The inclined design can reduce the residence time of impurities and reduce the probability of accumulation and blockage. The cooperation of the fixed plate 4, elastic support 5, adjusting component 6 and sealing frame 7 can control the lifting and lowering movement of the dredging component 8 under the action of rainwater, so as to dredge the filter holes of the filter cover 2 at regular intervals during the rainwater collection process.
[0024] The adjusting component 6 includes a base 601, on the top of which a water collection box 602 is fixedly installed. The inner cavity of the water collection box 602 has a first water outlet groove 603 flush with the bottom surface on both sides. The same second water outlet groove 701 is opened on the side wall of the sealing frame 7 and below the first water outlet groove 603. By collecting rainwater through the water collection box 602, its own weight can be increased, which can compress the elastic support 5 to contract and move downward, thereby achieving the effect of automatically adjusting the position of the unblocking component 8. When the second water outlet groove 701 is aligned with the first water outlet groove 603, it can automatically drain water to reduce weight, so that the adjusting component 6 can drive the unblocking component 8 to reset under the rebound force of the elastic support 5, thereby achieving the effect of repeatedly unblocking the filter holes of the filter cover 2.
[0025] In an embodiment of this utility model, the unblocking component 8 includes several fixed rods 801 of different lengths, and each fixed rod 801 penetrates the wall of the fixed plate 4. A horizontal plate 802 is fixedly installed at the lower end of each fixed rod 801. Fixed strips 803 are fixedly connected between the ends of the horizontal plates 802. A guide plate 804 that fits against the inner side of the filter cover 2 is fixedly installed between the fixed strips 803 on one side. Several unblocking blocks 805 that are inserted into the filter holes of the filter cover 2 are fixedly installed on the top surface of the guide plate 804. Through the cooperation, the stability of the vertical displacement of the guide plate 804 can be enhanced and the compressive strength can be improved.
[0026] In the embodiments of this utility model, each elastic support 5 includes a sleeve 501, a first spring 502 is fixedly disposed inside the sleeve 501, and a connecting rod 503 is fixedly disposed at the top end of the first spring 502, passing through the top of the sleeve 501 and connecting to the base 601; the extension and retraction effect can be achieved through the cooperation.
[0027] In an embodiment of this utility model, a triangular diversion strip 604 is fixedly provided on the bottom side of the inner cavity of the water collection box 602, and the two inclined surfaces of the triangular diversion strip 604 are flush with the bottom side of the water collection box 602; the design of the triangular diversion strip 604 can speed up the drainage speed and reduce rainwater residue.
[0028] In the embodiments of this utility model, the opposing surfaces of the sealing frame 7 are provided with a plurality of mounting grooves 702, and a plurality of second springs 703 are fixedly installed inside each mounting groove 702. A resistance strip 704 that abuts against the side of the water collection box 602 is fixedly connected between the second springs 703 in the same group. By supporting the resistance strip 704 with the second springs 703, the frictional resistance between the second springs 703 and the water collection box 602 can be increased, thus slowing down the movement speed.
[0029] In the embodiments of this utility model, the opposite sides of the water collection box 602 are provided with a plurality of resistance grooves 605 corresponding to the positions of the resistance strips 704, and the distance between the water collection box 602 and the resistance grooves 605 is the same as the distance between the water collection box 602 and the second water outlet 701; the two can be engaged when the first water outlet 603 and the second water outlet 701 are aligned, further increasing the displacement resistance, prolonging the alignment time of the first water outlet 603 and the second water outlet 701, and improving the drainage volume.
[0030] Working Principle: This embodiment provides a high-efficiency rainwater collection and filtration device for urban roads. When rainwater runoff from the road surface flows into this device, it first passes through the top filter baffle 3. The filter baffle 3 intercepts bulky debris such as leaves, plastic bags, and large branches, preventing them from entering the device and clogging the core components. The rainwater passing through the filter baffle 3 then falls onto the inclined surface of the filter cover 2. The triangular structure of the filter cover 2 effectively guides the water flow distribution, avoiding localized impacts. The rainwater can wash away fine particles (such as mud and dust) remaining on the surface, improving surface cleanliness. At the same time, some rainwater falls into the water collection box 602 located at the top of the filter cover 2. The water collection box 602, as the "power source" of this device, begins to accumulate rainwater. As rainfall continues, the weight of the rainwater accumulated in the water collection box 602 gradually increases. When the weight of the rainwater exceeds the sum of the pre-tightening support force of the elastic support 5 (i.e., the first spring 502) and the frictional force provided by the resistance strip 704, the entire adjusting component 6 (including the base 601 and the water collection box 602) will compress the elastic support 5 under the action of gravity and begin to move downward. The downward movement of the adjusting component 6 will cause the unblocking component 8 fixed at its bottom to move downward synchronously. The unblocking block 805 on the unblocking component 8, which was originally located inside the filter hole of the filter cover 2, will now release the blockage of the filter hole as the component moves downward, facilitating the filtration of rainwater. This allows the filtered rainwater to fall into the water storage tank 1 along the guide plate 804. When the adjusting component 6 moves down to a specific position, the first water outlet groove 603 on the side wall of the water collection box 602 will align and connect with the second water outlet groove 701 on the side wall of the sealing frame 7. At this time, the rainwater accumulated in the water collection box 602 will be quickly discharged through this aligned water outlet groove. The triangular diverter 604 inside the water collection box 602 facilitates the rapid and smooth discharge of water. During this process, the cooperation between the resistance strip 704 and the resistance groove 605 provides appropriate frictional damping, which prolongs the alignment and drainage time, allowing the weight of the water collection box 602 to be significantly reduced after the rainwater is quickly emptied. At this time, the restoring force of the compressed elastic support 5's first spring 502 becomes the dominant force, pushing the adjusting member 6 upward to return it to its initial position. After resetting, the first water outlet 603 and the second water outlet 701 are misaligned again, and the water collection box 602 returns to a closed state, ready to collect the next rainwater. The unblocking component 8 also rises accordingly, and the unblocking block 805 re-unclogs the filter holes to prepare for the next rainwater collection, thus keeping the filter holes unobstructed during continuous rainwater collection.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
