Description

Technical Field

[0001] This utility model relates to the field of rainwater purification technology, and more specifically, to a device for rainwater purification in sponge cities. Background Technology

[0002] Sponge cities are closely related to low-impact development. It is a new concept of urban stormwater management, also known as a water-resilient city. It refers to a city that can be as resilient as a sponge in adapting to environmental changes and coping with natural disasters caused by rainwater. In order to realize a sponge city, a rainwater collection and purification device is needed. The rainwater purification device is a device that collects, cleans and stores rainwater from the ground. Rainwater will collect and form puddles on urban roads. The puddles on the roads are generally introduced into the rainwater purification device through water pipes. This device plays a role in purifying rainwater resources.

[0003] The utility model with authorization announcement number CN208917959U provides a rainwater purification device for sponge cities. It uses a conveyor belt with permeable holes to transport garbage and debris in rainwater into the interior of a first cavity, separating rainwater from garbage and debris, thereby purifying rainwater.

[0004] However, in the aforementioned patent, one end of the conveyor belt extends into the first cavity, and the position of the conveyor belt cannot be changed. The conveyor belt will hinder the vertical movement of objects in the first cavity. Therefore, it is impossible to set up a garbage storage box that can be hoisted as a whole at the bottom of the first cavity to efficiently clean up the garbage and debris in the first cavity. When the amount of debris in the first cavity is too large, workers need to go down into the first cavity via a ladder and then manually clean up the debris in the first cavity. It is difficult for workers to carry cleaning tools in and out of the first cavity. When there is a lot of garbage and debris in the first cavity, workers need to transport the debris out of the first cavity in multiple times, resulting in low cleaning efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a device for rainwater purification in sponge cities, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, one of the objectives of this utility model is to provide a device for rainwater purification in sponge cities, comprising a housing, wherein a rainwater filtration assembly is disposed inside the housing, the rainwater filtration assembly includes a partition fixedly disposed inside the housing, a frame and a waste box are disposed between one side of the partition and the inner wall of the housing, the waste box is disposed on the lower side of the frame, the lower surface of the waste box is in contact with the bottom surface inside the housing, two belt rollers are rotatably disposed near both ends inside the frame, the two belt rollers are drivenly connected to the same strainer conveyor belt, one end of the strainer conveyor belt extends above the waste box, a drive assembly for driving one of the belt rollers to rotate is disposed on the frame, and a water inlet and a cleaning outlet are provided on the top of the housing. A drain pipe is fixedly connected to one side of the box near the bottom. The water inlet is located directly above the strainer conveyor belt, and the cleaning port is located directly above the waste box. A cover plate is installed between the cleaning port and the waste box. A rotating shaft is fixedly connected to one end of the cover plate. The two ends of the rotating shaft are rotatably connected to the inner wall of the box and the partition, respectively. Two extension shafts are symmetrically fixedly connected to the middle of opposite sides of the frame. The ends of the two extension shafts that are far apart from each other are rotatably connected to the inner wall of the box and the partition, respectively. One of the extension shafts and one end of the rotating shaft pass through the partition and are provided with the same transmission mechanism. When the cover plate rotates upward around the rotating shaft, the rotating shaft drives one of the extension shafts to rotate through the transmission mechanism, so that the extension shaft drives the frame and the strainer conveyor belt to rotate out from above the waste box.

[0007] As a further improvement to this technical solution, the transmission mechanism is located on the side of the partition away from the frame. The transmission mechanism includes a main sprocket coaxially fixedly connected to the rotating shaft, and a driven sprocket coaxially fixedly connected to the extension shaft. The driven sprocket and the main sprocket are connected by the same chain.

[0008] As a further improvement to this technical solution, an arc-shaped groove is provided on the partition plate, the axis of the arc-shaped groove and the axis of the extension shaft are on the same straight line, a sleeve is slidably arranged inside the arc-shaped groove, one end of the sleeve is fixedly set on the side wall of the frame, and the other end of the sleeve is fixedly connected to a bracket. The drive assembly includes a waterproof motor fixedly installed on the bracket, the output shaft of the waterproof motor is coaxially fixedly connected to one of the belt rollers, and the waterproof motor is located on the side of the partition plate away from the frame.

[0009] As a further improvement to this technical solution, a counterweight is fixedly connected inside the frame. The counterweight is located on the side of the extension shaft away from the drive assembly. A horizontally arranged baffle is fixedly connected to the side wall of the partition on the lower side of the frame. When the lower surface of the frame contacts the upper surface of the baffle, the frame is horizontal. One end of the strainer conveyor belt extends above the waste box.

[0010] As a further improvement to this technical solution, a handle is fixedly connected to the upper surface of the cover plate. The side profile of the handle is a T-shaped structure. The handle is close to the end of the cover plate away from the rotating shaft. When the cover plate is in a horizontal state, the cover plate blocks the cleaning port, and the lower surface of the horizontal section of the handle contacts the upper surface of the box.

[0011] As a further improvement to this technical solution, a scraper is fixedly installed inside the waste box near the top. When the conveyor belt is in a horizontal state, the upper end of the scraper contacts the lower side of the conveyor belt. A handle is fixedly connected to the center of the upper surface of the waste box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This device for rainwater purification in sponge cities rotates the cover plate upwards, causing the cover plate to rotate synchronously with the frame via a transmission mechanism. This causes the frame and one end of the strainer conveyor belt to rotate out from directly above the waste box, allowing workers to vertically lift the waste box out of the container using hoisting equipment. This improves the efficiency of workers cleaning the garbage and debris inside the waste box. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0030] Please see Figures 1-8As shown, one of the objectives of this embodiment is to provide a device for rainwater purification in sponge cities, including a housing 1 buried below the road surface of an urban road. A rainwater filtration assembly is installed inside the housing 1 to separate solid waste from road sludge. The rainwater filtration assembly includes a partition 3 fixedly installed inside the housing 1. A frame 5 and a waste box 4 are provided between one side of the partition 3 and the inner wall of the housing 1. The waste box 4 is located on the lower side of the frame 5, and its lower surface contacts the bottom surface inside the housing 1. Two belt rollers 51 are rotatably installed near both ends inside the frame 5. A common mesh conveyor belt 52 is driven and connected to the two belt rollers 51. The mesh conveyor belt 52 is a rubber conveyor belt with openings on it. Several drainage holes are provided, each containing a filter screen. The filter screen can block impurities in the rainwater. One end of the drain screen conveyor belt 52 extends above the waste box 4. The top of the box 1 has a water inlet 11, which is located directly above the drain screen conveyor belt 52. A drain pipe 13 is fixedly connected to one side of the box 1 near the bottom. When rainwater accumulates on city roads, it flows into the box 1 through the water inlet 11 and falls onto the drain screen conveyor belt 52. Then, the water flows through the drainage holes to the bottom of the box 1 and is discharged into the city's rainwater pipes through the drain pipe 13. The garbage and debris in the water cannot pass through the filter screen and remain on the upper side of the drain screen conveyor belt 52, thus preventing garbage and debris from entering the city's rainwater pipes and reducing the cleaning pressure on the city's rainwater pipes.

[0031] To prevent debris from clogging the filter screen of the conveyor belt 52 and reducing the efficiency of separating debris from rainwater for rainwater purification, a drive assembly is installed on the frame 5 to rotate one of the belt rollers 51. This drive assembly rotates the belt roller 51, causing the conveyor belt 52 to continuously transport the accumulated debris towards the waste bin 4. The debris then falls into the waste bin 4 under gravity, achieving automatic cleaning of the debris on the conveyor belt 52. To prevent some debris from adhering to the conveyor belt 52, a further cleaning mechanism is installed on the waste bin. An inclined scraper 41 is fixedly installed inside the box 4 near the top. The upper end of the scraper 41 contacts the lower side of the mesh conveyor belt 52. When the mesh conveyor belt 52 is running, the scraper 41 moves relative to the mesh conveyor belt 52. The scraper 41 scrapes off the garbage and debris adhering to the mesh conveyor belt 52. The garbage and debris scraped off by the scraper 41 will slide along the inclined surface of the scraper 41 into the interior of the waste box 4, thereby achieving efficient cleaning of garbage and debris on the mesh conveyor belt 52, effectively preventing garbage and debris from clogging the holes on the mesh conveyor belt 52, and ensuring the effect of this device in purifying rainwater.

[0032] The following details the structure of the driver component, refer to... Figure 4 , Figure 6 and Figure 7 An arc-shaped groove 31 is provided on the partition 3. The axis of the arc-shaped groove 31 is on the same straight line as the axis of the extension shaft 53. A sleeve 57 is slidably disposed inside the arc-shaped groove 31. One end of the sleeve 57 is fixedly disposed on the side wall of the frame 5, and the other end of the sleeve 57 is fixedly connected to a bracket 54. The drive assembly includes a waterproof motor 55 fixedly mounted on the bracket 54. The output shaft of the waterproof motor 55 is coaxially fixedly connected to one of the belt rollers 51, and the waterproof motor 55 is located on the side of the partition 3 away from the frame 5. When the waterproof motor 55 is started, the waterproof motor 55... The output shaft drives one of the belt rollers 51 to rotate. With the friction of the belt roller 51 on the strainer conveyor belt 52, the strainer conveyor belt 52 rotates between the two belt rollers 51. The rotating strainer conveyor belt 52 transports the filtered garbage to the waste box 4. With the help of gravity, the garbage falls into the waste box 4. Some garbage adheres to the strainer conveyor belt 52. The scraper 41 scrapes the strainer conveyor belt 52, causing the impurities adhering to the strainer conveyor belt 52 to also enter the waste box 4, thereby cleaning the garbage and debris accumulated on the strainer conveyor belt 52.

[0033] The waste container 4 has a limited capacity, so the waste inside needs to be cleaned regularly to prevent overflow. A drain outlet is located near the bottom of the waste container 4 on the side close to the drain pipe 13, allowing water to drain out and leaving only solid waste inside. To facilitate cleaning, a cleaning opening 12 is provided on the top of the container 1, directly above the waste container 4. A cover 2 is installed between the cleaning opening 12 and the waste container 4, with one end of the cover 2 fixedly connected to... A rotating shaft 22 is connected to the inner wall of the container 1 and the partition 3 at both ends, respectively. A handle 21 is fixedly connected to the upper surface of the cover 2. The side profile of the handle 21 is T-shaped. The end of the handle 21 closest to the cover 2 and furthest from the rotating shaft 22 is positioned so that the lower surface of the horizontal section of the handle 21 contacts the upper surface of the container 1, keeping the cover 2 in a horizontal position. In this horizontal position, the cover 2 blocks the cleaning opening 12, preventing road water from flowing into the waste container 4 and compressing the waste holding space. A carrying handle 42 is fixedly connected to the center of the upper surface of the waste container 4. Figure 8When workers need to clean the garbage and debris inside the waste box 4, they hold the handle 21 and rotate the cover plate 2 upwards, so that the end of the cover plate 2 away from the pivot 22 is rotated to the outside of the box 1 through the cleaning port 12, so that the device is in the open state of the cover plate 2. Then, the workers hook the hook of the hoisting equipment onto the handle 42 and use the hoisting equipment to lift the waste box 4 upwards, and lift the waste box 4 out of the box 1 through the cleaning port 12, so that the garbage and debris inside the waste box 4 can be cleaned quickly, and the garbage inside the waste box 4 can be prevented from overflowing.

[0034] However, because one end of the mesh conveyor belt 52 extends above the waste container 4, when the worker lifts the waste container 4 vertically upwards, the mesh conveyor belt 52 will prevent the waste container 4 from moving upwards. To solve this problem, refer to... Figure 3 , Figure 4 and Figure 8 Two extension shafts 53 are symmetrically fixedly connected at the middle of opposite sides of the frame 5. The ends of the two extension shafts 53 that are far apart from each other are rotatably connected to the inner wall of the box 1 and the partition 3, respectively. One of the extension shafts 53 and one end of the rotating shaft 22 pass through the partition 3 and are provided with the same transmission mechanism 6. When the cover plate 2 rotates upward about the rotating shaft 22, the rotating shaft 22 drives one of the extension shafts 53 to rotate through the transmission mechanism 6, so that the extension shaft 53 drives the frame 5 and the strainer conveyor belt 52 to rotate out from the top of the waste box 4. In this way, the frame 5 and the strainer conveyor belt 52 will no longer block the vertical upward movement of the waste box 4, making it convenient for workers to lift the waste box 4 out of the box 1 and improving the efficiency of workers to clean the garbage and debris inside the waste box 4.

[0035] The structure of transmission mechanism 6 is described in detail below, with reference to... Figure 4 The transmission mechanism 6 is located on the side of the partition 3 away from the frame 5. The transmission mechanism 6 includes a main sprocket 61 coaxially fixedly connected to the rotating shaft 22, and a driven sprocket 62 coaxially fixedly connected to the extension shaft 53. The driven sprocket 62 and the main sprocket 61 are connected by the same chain 63. When the worker rotates the cover plate 2 upward around the rotating shaft 22, the rotating shaft 22 drives the main sprocket 61 to rotate. The main sprocket 61 drives the driven sprocket 62 and one of the extension shafts 53 to rotate through the chain 63. The extension shaft 53 then drives the frame 5 and the strainer conveyor belt 52 to rotate. The end of the frame 5 and the strainer conveyor belt 52 near the waste box 4 moves away from the top of the waste box 4, thereby avoiding the frame 5 and the strainer conveyor belt 52 from blocking the vertical upward movement of the waste box 4, making it convenient for the worker to lift the waste box 4 out of the box 1.

[0036] When the frame 5 and the mesh conveyor belt 52 rotate, the sleeve 57 moves along the inner wall of the arc groove 31. The moving sleeve 57 will drive the bracket 54 and the waterproof motor 55 to move synchronously, thereby avoiding the rotation of the frame 5 and the mesh conveyor belt 52 from affecting the drive components. There is a communication port between the bottom of the partition 3 and the bottom surface inside the box 1. When some water splashes onto the side of the partition 3 away from the frame 5 through the arc groove 31, this water can return to the side of the partition 3 near the frame 5 through the communication port, so that the water inside the box 1 can be completely discharged through the drain pipe 13.

[0037] When workers do not need to clean the waste inside the waste box 4, in order to keep the frame 5 and the strainer conveyor belt 52 horizontal and allow the waste on the strainer conveyor belt 52 to fall into the waste box 4, a counterweight 56 ​​is fixedly connected inside the frame 5. The counterweight 56 ​​is located on the side of the extension shaft 53 away from the drive assembly. The counterweight 56 ​​keeps the center of gravity of the frame 5 between the extension shaft 53 and the end of the frame 5 closest to the waste box 4, thereby preventing the waterproof motor 55 from pressing down on one end of the frame 5, causing the frame 5 to be close to the waste box 4. One end of the waste box 4 is tilted upwards, and a horizontally arranged baffle 32 is fixedly connected to the side wall of the partition 3 on the lower side of the frame 5. When the lower surface of the frame 5 contacts the upper surface of the baffle 32, the frame 5 is horizontal, thus preventing the counterweight 56 ​​from pressing down the other end of the frame 5, so that the end of the frame 5 away from the waste box 4 tilts upwards, so that the frame 5 and the strainer conveyor belt 52 remain in a horizontal state when the worker does not apply force to rotate the cover plate 2 upwards, so that the garbage and debris on the strainer conveyor belt 52 can be transported to the waste box 4 for centralized treatment.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
