Description

Technical Field

[0001] This utility model relates to the field of sponge city technology, specifically a water storage structure for sponge city road construction. Background Technology

[0002] In the construction of sponge city roads, a stable and efficient water storage structure is required. Existing technologies (such as CN221741477U) utilize drainage channels to conduct rainwater and sewage through diversion pipes to the interior of the storage tank. The storage tank then uses filters, sand layers, activated carbon layers, and filter cotton layers inside to filter and purify the water before storing it for later use, thus achieving a backup water storage function.

[0003] However, the structure still has the following shortcomings when in use: it lacks a structure for pre-filtering solid impurities in the water before the rainwater enters the storage tank. Since the storage tank is buried in the soil of the green belt, a large amount of solid impurities will increase the frequency of internal filter replacement when they enter the tank. Since it is buried in the soil, it is not convenient to clean and replace the filter. Therefore, it is particularly important to reduce the frequency of filter replacement in the storage tank.

[0004] In view of this, this application proposes a water storage structure for sponge city road construction to solve the above-mentioned problems. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By using a combination of a drain trough, conical support sleeve, funnel-shaped filter plate and slag collection cylinder, solid impurities in the water can be pre-filtered, intercepted and collected before the rainwater enters the storage tank. This reduces the phenomenon of frequent internal component replacement caused by a large amount of solid impurities entering the storage tank. Since the slag collection cylinder is located at the position of the rain grate, the impurities can be removed directly, improving the convenience of impurity cleaning.

[0022] 2. By combining the funnel-shaped filter plate, L-shaped air inlet pipe, air pipe connector, wind-driven ventilation component and rotary back-blowing cleaning and unblocking component, the funnel-shaped filter plate can be thoroughly back-blown cleaned and unblocked during heavy rain or floods, in conjunction with external air supply measures. This improves the filtration smoothness of the funnel-shaped filter plate, reduces the risk of blockage leading to water blockage, and further improves the stability of pre-filtration treatment.

[0023] 3. By using a conical support, funnel-shaped filter plate, slot and block provided in another way, it is convenient for personnel to directly remove the funnel-shaped filter plate after opening the rain grate. This facilitates subsequent replacement and better removal of the slag collection cylinder for cleaning impurities, further improving the convenience of solid slag cleaning.

[0024] This utility model incorporates a series of structures that facilitate the pre-filtration, interception, and collection of solid impurities in rainwater before it enters the storage tank. This reduces the likelihood of large amounts of solid impurities entering the storage tank, which would otherwise lead to frequent replacement of internal components. Furthermore, the rain grate can be directly removed from the slag collection cylinder, improving the ease of impurity cleaning. It also allows for comprehensive backflushing and unblocking of the funnel-shaped filter plate during heavy rains or floods, improving the filtration efficiency of the funnel-shaped filter plate, reducing the risk of blockage and water stagnation, and further enhancing the stability of the pre-filtration process.

Detailed Implementation

[0031] 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.

[0032] Example 1

[0033] like Figure 1 As shown:

[0034] A water storage structure for sponge city road construction includes a water storage structure body, which includes a drainage trough 1 embedded in the top of the roadbed 100 and a water storage tank 102 embedded in the soil 200 of the green belt. The bottom of the drainage trough 1 is connected to the top left side of the water storage tank 102 and a diversion pipe 101 is fixed thereon.

[0035] In this implementation plan: The existing device {publication (announcement) number}: CN221741477U discloses a storage structure for sponge city road construction. The storage tank 102 in this application adopts the same technical means as the prior art. The technical means will not be described in detail here. This application further improves the main body of the prior art. For details, please refer to the following disclosure. In order to solve the technical problems existing in the prior art, such as the "lack of a structure for pre-filtering solid impurities in the water before the rainwater enters the storage tank" disclosed in the background art above, (since the storage tank is buried in the soil of the green belt, a large amount of solid impurities will increase the frequency of internal filter replacement. Since it is buried in the soil, it is not convenient to clean and replace the filter. Therefore, it is particularly important to reduce the frequency of filter replacement in the storage tank)". In combination, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a pre-filtration mechanism is added to this application.

[0036] It should be noted that the components used in the storage tank 102 have been disclosed in publication number CN221741477U, and their performance can be referred to publication number CN221741477U (i.e., the "fixed frame, filter screen, sand layer, activated carbon layer, and filter cotton layer components" disclosed in this prior art).

[0037] Furthermore:

[0038] like Figures 1-4 As shown: A pre-filtration mechanism is installed in the drain tank 1;

[0039] The pre-filtration unit includes:

[0040] Rain grate 201 is movably installed on the top of the inner side of the drain trough 1;

[0041] The conical support sleeve 2 is fixedly connected to the inside of the drain trough 1 and makes movable contact with the bottom of the grate 201;

[0042] The funnel-shaped filter plate 3 is connected to the top of the conical support sleeve 2. Two symmetrically arranged circular rings are fixedly connected to the top of the inner side of the funnel-shaped filter plate 3. The bottom of the funnel-shaped filter plate 3 is connected to and fixedly connected to the slag collection cylinder 301. Multiple filter holes are provided on the outer side of the slag collection cylinder 301 and the outer side of the funnel-shaped filter plate 3. The funnel-shaped filter plate 3 is used to filter and intercept solid impurities in rainwater, and uses its inner inclined surface to guide and collect solid impurities into the slag collection cylinder 301. The multiple filter holes on the slag collection cylinder 301 are used to allow water entering its interior to seep out. The filtered water is then guided through the guide pipe 101 to the storage tank 102 for treatment and storage.

[0043] The wind-driven vortex ventilation assembly is installed between the front and rear inner walls of the lower water tank 1. An L-shaped air inlet pipe 401 is connected and fixed on the right side of the wind-driven vortex ventilation assembly. One end of the L-shaped air inlet pipe 401 extends to the outside of the roadbed 100 and is connected and fixed with an air pipe connector for connecting with external air supply equipment or air supply pipeline. A through hole is provided at the bottom right side of the lower water tank 1 for the L-shaped air inlet pipe 401 to pass through and be fixedly connected to its outer side.

[0044] The rotary backflushing cleaning and unblocking component is fixed to the left side of the wind-driven vortex ventilation component and cooperates with the bottom of the funnel-shaped filter plate 3. It is used in areas prone to water accumulation. The air pipe connector is used to connect to external air supply equipment or the branch end of the laid air supply pipeline. During heavy rain, it is controlled by the staff to supply air into the L-shaped air inlet pipe 401. The wind-driven vortex ventilation component is used to drive the rotary backflushing cleaning and unblocking component to rotate and supply air into it when supplying air into the L-shaped air inlet pipe 401. The rotary backflushing cleaning and unblocking component is used to thoroughly backflush and unblock the funnel-shaped filter plate 3 during rotation and air supply.

[0045] It should be noted that both the funnel-shaped filter plate 3 and the slag collection cylinder 301 are made of stainless steel. The advantages of stainless steel, such as high hardness and strong corrosion resistance, are utilized to ensure its long-term application stability.

[0046] Furthermore, the funnel-shaped filter plate 3 is glued to the top of the conical support 2.

[0047] Furthermore, such as Figure 3 and 4 As shown, the wind-driven swivel ventilation assembly includes a swivel base 4, a rotating shaft 402, impeller blades 403, and a circular box 405. The swivel base 4 is fixedly connected between the front and rear inner walls of the lower water tank 1. The rotating shaft 402 is sealed and rotatably embedded between the top and bottom of the swivel base 4. There are multiple impeller blades 403, which are fixedly connected to the outside of the rotating shaft 402 in an annular pattern with equal spacing. All the impeller blades 403 are located inside the swivel base 4. The bottom of the circular box 405 is set as an opening and is sealed and rotatably installed on the top of the swivel base 4. The top inner wall of the circular box 405 is fixedly connected to the top of the rotating shaft 402. The top of the swivel base 4 has four connecting holes 404 that are all connected to the inside of the circular box 405 in an annular pattern with equal spacing. The left end of the L-shaped air inlet pipe 401 is connected and fixed to the right side of the swivel base 4 and is laterally aligned with the front impeller blades 403.

[0048] In this embodiment, the top and bottom of the U-shaped seat 4 are provided with fitting round holes, and a first sealing bearing is fixedly fitted in the fitting round hole. The inner rings of the two first sealing bearings are fixedly fitted to the outer side of the rotating shaft 402, so as to achieve the effect of sealing and rotating the rotating shaft 402. The top of the U-shaped seat 4 is fixedly connected to a second sealing bearing, and the inner ring of the second sealing bearing is fixedly fitted to the outer side of the round box 405. The round box 405 is sealed and rotated on the top of the U-shaped seat 4 through the second sealing bearing, so as to achieve the effect of rotating the round box 405.

[0049] In this embodiment, the combination of the U-shaped seat 4, the rotating shaft 402, the impeller blades 403, and the circular box 405 allows high-pressure gas to be supplied into the L-shaped air inlet pipe 401. The gas blows the front impeller blades 403 to rotate, which in turn drives the rotating shaft 402 to rotate. The rotating shaft 402 then drives multiple other impeller blades 403 to rotate sequentially until they are blown by the gas and continuously provided with rotational force. When the rotating shaft 402 rotates, it drives the circular box 405 to rotate. The gas blown into the U-shaped seat 4 is supplied into the circular box 405 through four connecting holes 404.

[0050] Furthermore, such as Figure 3 and 4 As shown, the rotary backflushing cleaning and unblocking assembly includes a one-way valve 5, an L-shaped pipe 501, a horizontal pipe 502, and a blow-through head 503. The one-way valve 5 is fixed to the left side of the round box 405. The left side of the one-way valve 5 is the outlet and is fixed to the right end of the L-shaped pipe 501. The horizontal pipe 502 is inclined and fixed to the top of the L-shaped pipe 501. The left end of the horizontal pipe 502 is set as a sealing structure. There are multiple blow-through heads 503, which are fixed to the top of the horizontal pipe 502 at equal intervals. The blow-through heads 503 are located below the funnel-shaped filter plate 3 and cooperate with it. The left side of the round box 405 and the inner left side of the L-shaped pipe 501 are fixedly connected by the same inclined reinforcing rib.

[0051] In this implementation scheme, the one-way valve 5, L-shaped pipe 501, horizontal pipe 502, and purge nozzle 503 work together. When the circular box 405 rotates, the one-way valve 5 and L-shaped pipe 501 sequentially drive the horizontal pipe 502 to rotate. The horizontal pipe 502 drives multiple purge nozzles 503 to rotate. When gas is supplied into the circular box 405, it passes through the one-way valve 5 into the L-shaped pipe 501, then into the horizontal pipe 502, and then is blown out upwards by the multiple rotating purge nozzles 503. This achieves a comprehensive backflushing cleaning and unblocking of the funnel-shaped filter plate 3 from bottom to top. Combined with the inclined surface on the inner side of the funnel-shaped filter plate 3, it allows solid slag and impurities to slide down and concentrate in the slag collection cylinder 301. By rotating to perform a comprehensive backflushing cleaning and unblocking method, the filtration smoothness of the funnel-shaped filter plate 3 is improved, the risk of blockage leading to water blockage is reduced, and the stability of pre-filtration treatment is improved.

[0052] It should be noted that the L-shaped tube 501, horizontal tube 502, blow-through tube head 503, U-shaped seat 4 and round box 405 are all made of stainless steel. The advantages of stainless steel, such as high hardness and strong corrosion resistance, are utilized to ensure its long-term application stability.

[0053] This embodiment facilitates the pre-filtration, interception, and collection of solid impurities in the water before it enters the storage tank 102, reducing the frequent replacement of internal components caused by a large amount of solid impurities entering the storage tank 102. Since the rain grate 201 can be directly removed from the slag collection cylinder 301, the convenience of impurity cleaning is improved. Furthermore, it is convenient to combine external air supply measures to fully backflush and clean the funnel-shaped filter plate during heavy rain or floods, improving the filtration smoothness of the funnel-shaped filter plate 3, reducing the risk of blockage and water blockage, and further improving the stability of pre-filtration treatment.

[0054] The usage method of this embodiment is as follows: When the rainwater enters through the through holes on the rain grate 201, the funnel-shaped filter plate 3 filters and intercepts solid impurities in the rainwater, and the inner inclined surface guides and collects the solid impurities into the slag collection cylinder 301. The multiple filter holes on the slag collection cylinder 301 are used to allow the water entering it to seep outward. The filtered water is then guided through the guide pipe 101 to the storage tank 102 for treatment and storage. This achieves the effect of pre-filtering, intercepting and collecting solid impurities in the water before the rainwater enters the storage tank 102, reducing the phenomenon of frequent replacement of internal parts caused by a large amount of solid impurities entering the storage tank 102. Since the location of the slag collection cylinder 301 allows the rain grate 201 to be directly removed to remove impurities, the convenience of impurity cleaning is improved.

[0055] This application is primarily intended for use in areas prone to water accumulation. In such applications, one end of the L-shaped air inlet pipe 401 is connected to an external air supply device or a branch of a pre-laid air supply pipeline. During periods of heavy rain and flooding, when personnel activate the external air supply device or utilize multiple points of concentrated air supply near the pre-laid air supply pipeline, high-pressure gas enters the L-shaped air inlet pipe 401. This gas then blows the front impeller blade 403, causing it to rotate. The front impeller blade 403 drives the rotating shaft 402 to rotate, which in turn drives multiple other impeller blades 403 to rotate sequentially until they are continuously propelled by the gas, providing rotational force. The rotation of the rotating shaft 402 also drives the circular box 405 to rotate. The gas blown into the U-shaped seat 4 is supplied through the four connecting holes 404. Inside the circular box 405, as the circular box 405 rotates, it sequentially drives the horizontal pipe 502 to rotate through the one-way valve 5 and the L-shaped pipe 501. The horizontal pipe 502 drives multiple cleaning nozzles 503 to rotate. When gas is supplied into the circular box 405, it passes through the one-way valve 5 into the L-shaped pipe 501, then into the horizontal pipe 502, and then is blown out upwards by the multiple rotating cleaning nozzles 503. This achieves a comprehensive backflushing cleaning and unblocking of the funnel-shaped filter plate 3 from bottom to top. Combined with the inclined surface on the inner side of the funnel-shaped filter plate 3, it allows solid slag and impurities to slide down and concentrate in the slag collection cylinder 301. By rotating to perform a comprehensive backflushing cleaning and unblocking method, the filtration smoothness of the funnel-shaped filter plate 3 is improved, the risk of blockage leading to no water flow is reduced, and the stability of pre-filtration treatment is improved.

[0056] Example 2

[0057] like Figure 5 As shown, this embodiment differs from Embodiment 1 in that the funnel-shaped filter plate 3 is detachably connected to the top of the conical support 2, the funnel-shaped filter plate 3 is in movable contact with the top of the conical support 2, and the top of the conical support 2 is provided with four slots 202 at equal intervals in an annular shape, and a card block 302 fixedly connected to the funnel-shaped filter plate 3 is movably installed in the slots 202.

[0058] This embodiment allows personnel to easily remove the funnel-shaped filter plate 3 directly upwards after opening the rain grate 201, facilitating its replacement and easier removal of the slag collection cylinder 301 for cleaning impurities, thus further improving the convenience of solid slag cleaning.

[0059] The method of use in this embodiment is as follows: The difference from the first embodiment is that it also has the following functions: The slot 202 and the block 302 are used to form a convenient way to lock and position the funnel-shaped filter plate 3. Afterwards, the funnel-shaped filter plate 3 can be directly taken out upwards after the rain grate 201 is opened, which facilitates the replacement of the filter plate and the removal of the slag collection cylinder 301 to clean impurities, thereby further improving the convenience of solid slag cleaning.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
