[0002] The present invention further relates to a fixed-point water intake device based on the filter.

[0003] The present invention further relates to a smart city ecological water intake device based on the above-mentioned fixed-point water intake device.

[0004] The present invention further relates to a construction method based on the above-mentioned smart city ecological water intake device. Background Art

[0005] For example, the Chinese utility model patent announcement number CN 201553659 U discloses a direct suction water purifier, including an outer sleeve with a hollow cavity and a suction nozzle connected to the outer sleeve, a water inlet is provided at the end of the outer sleeve, a water outlet is provided at the end of the suction nozzle, the inner cavity of the outer sleeve is provided with a primary filter and a fine filter in sequence from the water inlet, an inner sleeve is provided inside the suction nozzle, a compression spring is provided on the outer sleeve, a valve device is provided between the fine filter and the inner sleeve, and the inner sleeve is filled with far-infrared functional ceramic balls that replicate far-infrared and wave energy. It has the problem that the water inlet is easily blocked by impurities, resulting in a reduction in water intake.

[0006] In many cities today, especially second- and third-tier cities, ecological water operations such as green irrigation, municipal dust reduction sprinkling, and shipping water use all draw water from urban fire hydrants, urban grey water pipelines, ponds, lakes, rivers, and the sea, and usually adopt an agreed charging method, which cannot be accurately measured. Moreover, manual operation is required during use, which often causes damage to fire hydrants, resulting in the inability to accurately manage water resources and posing a great safety hazard to urban fire protection.

[0007] In order to facilitate the scientific and intelligent water use and water extraction of users such as gardening, greening, municipal administration, sanitation, and irrigation, prevent water theft by lawless elements, and manage water control data scientifically and effectively, some products have appeared in recent years. For example, a stainless steel outer box is installed near the fire hydrant, and a card-swipe water extraction device is placed in the outer box. From the perspective of use, it can only solve the simple card-swipe water extraction problem. In addition, the opening and closing of valves of many products are either done manually with a wrench, or an electric ball valve is installed to control the switch. A large part of the electric ball valve is powered by the lithium battery inside the product. Once the lithium battery is exhausted, the electric ball valve may not be able to open or close normally. If it is needed If this problem occurs when the valve is closed, it will cause a waste of water resources. When the valve is manually switched on and off, once it is stuck, it may not turn and cannot be closed or used normally. In addition, due to the complexity of water quality in rivers, lakes, ponds, and seawater, water intake terminals are often blocked and damaged. Some fire hydrants in cities are often damaged by vehicle collisions, causing large-scale water accumulation on the road. Foreign objects are easily introduced into the water outlet, causing pipe blockage or the electric ball valve to get stuck and not close tightly. The detection components and water pipe joints of the water dispenser are exposed to the outside all year round. Over time, they will age and be damaged or maliciously damaged, which increases the cost of replacement and use, resulting in poor practicality. Summary of the invention

[0008] One object of the present invention is to provide a filter which can clean impurities at a water inlet and prevent the impurities from clogging the water inlet, and is suitable for use in natural water resources such as rivers, and is convenient for underwater water filtration and water intake.

[0009] Another object of the present invention is to provide a fixed-point water intake device based on the above-mentioned filter, which can be positioned underwater, stabilize the water intake point, and prevent the water intake point from shifting.

[0010] Another object of the present invention is to provide a smart city ecological water intake device based on the above-mentioned fixed-point water intake device, which is convenient for establishing a new mode of municipal water use along the river, sharing the pressure of municipal water use, and reducing the waste of tap water resources.

[0011] A further object of the present invention is to provide a construction method based on the above-mentioned smart city ecological water intake device, which facilitates the construction of the above-mentioned smart city ecological water intake device.

[0012] For the technical topic of filters, it includes:

[0013] The pressurized chamber comprises a bottom wall, a first circumferential wall surrounding the bottom wall and an internal pressurized chamber, holes for water inlet are distributed on the circumferential wall to form a circular close-mesh grid, and a long strip grid is arranged at the lower part of the pressurized chamber;

[0014] The motor cover is mounted on the back of the bottom wall;

[0015] A control motor is installed in the motor cover, and its rotating shaft passes through the bottom wall of the pressurized chamber;

[0016] The blades are distributed on a chassis, the chassis is fixedly connected to the rotating shaft of the control motor, the blades are evenly spaced at an angle, one end of the blade is distributed at the edge of the chassis and is spaced from the circumferential wall of the pressurized chamber, and the other end of the blade extends toward the middle of the chassis along a spiral line, so that the installation angle of the blade is adjustable, and the blade separates a plurality of water inlet channels with a gradually changing cross section in the pressurized chamber;

[0017] The water storage chamber comprises a water outlet end wall, a second circumferential wall surrounding the water outlet end wall and an inner water storage chamber, wherein the second circumferential wall is butted against the first circumferential wall so that the pressurizing chamber and the water storage chamber are connected, and a hole is opened on the water outlet end wall to connect with a fixed water pipe;

[0018] The cleaning scraper assembly is mounted on the blade and has a cleaning scraper. The cleaning scraper protrudes from one end of the blade close to the first circumferential wall and extends to the inner surface of the first circumferential wall.

[0019] With such a structure, the blades at the interface position rotate at a high speed, so that the flow rate of the liquid on the inner wall surface of the pressurized chamber is much higher than the flow rate of the liquid on the outer wall surface of the pressurized chamber, thereby easily forming internal and external negative pressures, causing water to be sucked into the pressurized chamber, thereby squeezing the water in the middle of the pressurized chamber into the water storage chamber. The outer cross-section of the water inlet channel with a gradient cross-section is larger than the inner cross-section, so that more water enters the outer cross-section and less water flows out of the inner cross-section, so as to maintain the water pressure in the middle of the pressurized chamber higher than the water pressure in the water storage chamber, thereby forming a water flow path from the pressurized chamber to the water storage chamber.

[0020] At this time, when the cleaning scraper assembly rotates, it not only plays a cleaning role, but also drives the water flow at the interface position to rotate at a high speed to maintain negative pressure.

[0021] This structure forms a lateral vortex from left to right, and water flows out from the upper end (such as the left end of the water storage chamber) of the lateral controllable vortex (such as the lateral vortex formed in the water storage chamber), and sediment settles on the lower side (such as sediment settles on the lower side wall of the water storage chamber), and the speed of the vortex is controlled by controlling the installation angle of the blades and the rotation speed of the motor.

[0022] As a further improvement of the filter, a filter disc is arranged between the water storage chamber and the pressurized chamber, an inner flange is arranged at one end of the first circumferential wall close to the water storage chamber, the first circumferential wall is fixedly connected to the second circumferential wall, and the filter disc is installed at the end of the water storage chamber and then docked to the inner flange.

[0023] Such a structure makes it easy to install the filter disc.

[0024] As a further improvement of the filter, the cleaning scraper assembly also includes a cleaning scraper base, a compression spring, an adjusting bolt, an adjusting bolt seat and a scraper fixing seat. The adjusting bolt is connected to the adjusting bolt seat through a thread. The lower end of the adjusting bolt passes through the scraper fixing seat. The upper part of the scraper fixing seat is slidably sleeved in the cleaning scraper base. The upper part of the scraper fixing seat is T-shaped, and the lower part of the cleaning scraper base has a step surface. The two sides of the T-shaped upper part of the scraper fixing seat can overlap the step surface of the lower part of the cleaning scraper base. The compression spring is arranged between the upper plate of the cleaning scraper base and the top surface of the scraper fixing seat. The adjusting bolt seat is arranged on the upper plate of the cleaning scraper base and is threadedly connected to the adjusting bolt. The cleaning scraper base is fixed on the blade.

[0025] Such a structure can prevent the cleaning scraper assembly from getting stuck during rotation. The cleaning scraper has the function of flexible extension and retraction. When encountering impurities with higher hardness, the cleaning scraper can retract inward, thereby maintaining the cleaning function and preventing the rotation process from getting stuck.

[0026] As a further improvement of the filter, a mud removal port is arranged at the bottom of the water storage chamber, and the mud removal port is covered with a mud removal port sealing plate. One side of the mud removal port sealing plate is hinged to the outer wall of the water storage chamber, and the other side is provided with a hook to connect the lower end of the mud removal port hanging spring. The upper end of the mud removal port hanging spring is fixedly connected to the hanging plate on the outer wall of the water storage chamber.

[0027] With such a structure, heavier impurities will settle downwards under the action of gravity. The mud removal port sealing plate is usually closed. When the impurities accumulate to a certain weight, the lower end of the mud removal port hanging spring is extended, the mud removal port sealing plate is opened, and the impurities can be removed.

[0028] As a further improvement of the filter, the fixed water pipe is connected to the collecting water pipe, and the collecting water pipe is connected to the water outlet pipe.

[0029] Such a structure facilitates the formation of a water outlet channel.

[0030] For the topic of fixed-point water intake devices, it includes:

[0031] The above filters;

[0032] A double-defense prefabricated pier for accommodating the filter is made of prefabricated concrete, and includes a pier body, a front pier and a rear pier; the pier body is hollow inside, and a mounting groove is arranged on its side to install the filter, and the front end of the pier body has a convex portion; the rear end of the front pier has a concave portion to combine with the convex portion of the front end of the pier body, the front end of the front pier adopts a shark head bionic structure, a water collection port is arranged on the front pier, and the ends of several water collection ports are connected to the cavity inside the pier body after being collected, the rear pier cover is arranged on the pier body, and its rear end extends a part exceeding the pier body; a connecting hole is arranged on the top surface of the front pier, and bolt-type assembly is realized with the pier body through a precast cement connecting bolt; a rear pier connecting port is arranged on the top surface of the rear pier, and bolt-type assembly is realized with the pier body through a precast cement connecting bolt, and a pier reinforcing conical foot is arranged under the pier body.

[0033] With such a structure, the density of concrete is much greater than the density of water. Precast concrete is used to facilitate on-site assembly. The front pier and the rear pier form front, rear and top protections. The pier reinforced conical feet with a cone shape at the lower end can be fixed in the riverbed. The pier reinforced conical feet are inserted into the riverbed for a section to reserve space between the riverbed and the bottom of the pier body, which is convenient for water inlet and sewage discharge at the bottom of the water filter.

[0034] This structure is mainly used to solve the problem of the filter being displaced by the impact of debris in the water and being buried by sediment accumulation.

[0035] With this structure, the front end of the front pier adopts a shark head bionic design, which can effectively decompose the impact force of water flow and debris on it and ensure its position stability;

[0036] As a further improvement of the fixed-point water intake device, the front end of the front pier adopts an annular concave structure, and a plurality of radially distributed water collection ports are arranged at the concave part.

[0037] After the ends of several water collection ports are gathered together and connected to the cavity inside the pier body, it is convenient for water to enter the multiple water collection ports and prevent blockage.

[0038] With such a structure, the rear pier cover is arranged on the pier body, and its rear end extends a section beyond the pier body, which can prevent sediment and debris from settling here.

[0039] With such a structure, the water collection port at the concave part is narrow at the upper and lower sides, and is not easily blocked by large objects or clogged.

[0059] With such a structure, the intelligent ecological water intake pump room pumps the filtered ecological river water into the urban ecological intelligent water intake device for use by pedestrians, and the placement platform of the urban ecological intelligent water intake device is easy to level.

[0060] Regarding the construction method of the smart ecological water intake device of sponge city, it specifically includes the following steps:

[0061] S1: Determine the diameter of the water intake pipe and the specifications of the water pump. The standard reference is: "Design Standard for Building Water Supply and Drainage" GB50015-2019;

[0062] It is necessary to select the appropriate water intake pipe diameter and water pump specifications according to the local designed water intake volume;

[0063] S2: Determine the size and installation position of the grid on the filter's pressurized chamber and the grid on the filter disc according to the river water flow rate, water intake volume, and water intake pipe diameter;

[0064] S3: Determine the size of the double-defense prefabricated piers and water pipe support piers according to the buoyancy of the river water, the riverbed soil, and the maximum flow rate of the river water. If the river water density is large, the buoyancy is strong, the riverbed soil is loose, and the river flow rate is fast, consider increasing the size to make the double-defense prefabricated piers and water pipe support piers safer and more stable to use; adjust the position of the water intake pipe on the support pier according to the final settlement position of the water pipe support pier in the water and the final installation position of the smart ecological water intake pump chamber; install the water intake pipe after the water pipe support pier and the smart ecological water intake pump chamber have settled evenly and stably.

[0065] S4: The prefabrication site of the double-protection prefabricated pier should be arranged according to the assembly line, with raw material area, steel bar processing area, concrete pouring area, maintenance area, and finished product storage area; the prefabrication site should be flat and solid, and hardened with concrete; and waterproof, drainage, and fire prevention measures should be taken;

[0066] S5: Pre-installation of double-protection prefabricated piers and filters at the prefabrication site;

[0067] S6: Use the assembled double-protection prefabricated piers and filters, and place them in the river channel with the supporting piers, and adjust the placement position. After the installation is completed, install the water intake pipe;

[0068] S7: Install and construct the intelligent ecological water pump room at the designed location;

[0069] S8: Install a water pipe connected to the water inlet joint on one side of the smart ecological water pump chamber, and extend the water pipe to the support pier on the river channel through the reserved holes on the smart ecological water pump chamber; seal the connection positions between the water intake pipes and between the water intake pipes and the filter;

[0070] S9: Install and fix the urban ecological intelligent water intake device on the urban ecological intelligent water intake device placement platform, connect the outlet pipe of the intelligent ecological water intake pump room, and seal the connection position;

[0071] S10: Check and accept the quality of concrete, water leakage, pipe water quality, and riverbed undercurrents.

[0072] This approach makes it easier to construct smart ecological water intake devices in sponge cities, so as to establish ecological water intake routes and share the pressure of municipal water use.

[0073] As a further improvement of the construction method, the specific steps of S5 include: using the prefabrication method of the smart ecological water pump room and placing it above the ground surface, only strengthening the foundation at the designed position, leveling the installation position, placing the smart ecological water pump room and fixing it;

[0074] Alternatively, the smart ecological water pump room can be prefabricated and placed below the surface, with only pit digging, foundation reinforcement, and installation position leveling required, and then landfill after placement;

[0075] Alternatively, the intelligent ecological water pump room may be cast in place or built by masonry.

[0076] In this way, the intelligent ecological water pump room can be prefabricated or cast in place, and can be installed on the surface or underground, making it easy to choose the specific setting method according to the specific situation.

[0077] The present invention is suitable for taking water from rivers and lakes. It can improve the water intake efficiency while preventing animals and plants from entering the intelligent ecological water intake pump room, clogging the water pump and damaging the purification system. The filter can remove impurities and perform excellent filtering and impurity removal work through the coordinated effects of impurity removal and filtration. At the same time, a double-collision and anti-sand accumulation water flow appearance setting is adopted for the double-protection prefabricated pier, which can effectively avoid the collision of underwater debris and the accumulation of silt. The overall construction of the present invention is simple, the construction cost is saved, the principle is clear, the implementation and operation are convenient, and the materials are easily available. The control requirements are general, which can well meet the actual construction needs and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS

[0105] Motor cover 3-1; which is installed on the back of the bottom wall;

[0106] A control motor 3-2 is installed in the motor cover 3-1, and its rotating shaft passes through the bottom wall of the pressurized chamber;

[0108] The water storage chamber comprises a water outlet end wall and a second circumferential wall surrounding the water outlet end wall and an internal water storage chamber 3-7, wherein the second circumferential wall is butted against the first circumferential wall so that the pressurizing chamber 3-3 and the water storage chamber 3-7 are connected, and a hole is opened on the water outlet end wall to connect with a fixed water pipe 3-8;

[0109] The cleaning scraper assembly 3-5 is mounted on the blade and has a cleaning scraper 3-5-5. The cleaning scraper 3-5-5 protrudes from one end of the blade close to the first circumferential wall and extends to the inner surface of the first circumferential wall.

[0110] With such a structure, the blades at the interface position rotate at a high speed, so that the flow rate of the liquid on the inner wall surface of the pressurized chamber is much higher than the flow rate of the liquid on the outer wall surface of the pressurized chamber, thereby easily forming internal and external negative pressures, causing water to be sucked into the pressurized chamber, thereby squeezing the water in the middle of the pressurized chamber into the water storage chamber. The outer cross-section of the water inlet channel with a gradient cross-section is larger than the inner cross-section, so that more water enters the outer cross-section and less water flows out of the inner cross-section, so as to maintain the water pressure in the middle of the pressurized chamber higher than the water pressure in the water storage chamber, thereby forming a water flow path from the pressurized chamber to the water storage chamber.

[0111] At this time, when the cleaning scraper assembly 3-5 rotates, it not only plays a cleaning role, but also drives the water flow at the interface position to rotate at a high speed to maintain negative pressure.

[0115] In this embodiment, the cleaning scraper assembly 3-5 also includes a cleaning scraper base 3-5-2, a compression spring 3-5-3, an adjusting bolt 3-5-1, an adjusting bolt seat 3-5-6 and a scraper fixing seat 3-5-4. The adjusting bolt 3-5-1 is connected to the adjusting bolt seat 3-5-6 through a thread. The lower end of the adjusting bolt 3-5-1 is connected to the scraper fixing seat 3-5-4. The upper part of the scraper fixing seat 3-5-4 is slidably sleeved in the cleaning scraper base 3-5-2. The upper part of the scraper fixing seat 3-5-4 is T-shaped. Type, the lower part of the cleaning scraper base 3-5-2 has a step surface, and the two sides of the T-shaped upper part of the scraper fixing seat 3-5-4 can overlap on the lower step surface of the cleaning scraper base 3-5-2, the compression spring 3-5-3 is arranged between the upper plate of the cleaning scraper base 3-5-2 and the top surface of the scraper fixing seat 3-5-4, the adjusting bolt seat 3-5-6 is arranged on the upper plate of the cleaning scraper base 3-5-2, and is threadedly connected to the adjusting bolt 3-5-1, and the cleaning scraper base 3-5-2 is fixed on the blade 3-4.
