Description

Technical Field

[0001] The invention belongs to the technical field of water purification, in particular to a device for monitoring and purifying eutrophication of urban landscape water. Background Art

[0002] Urban landscape water bodies, such as lakes and artificial rivers in urban parks, are important components of the urban ecological environment. They not only beautify the urban landscape and regulate the local climate, but also provide places for citizens to relax and entertain, thus improving the quality of life of urban residents.

[0003] However, with the acceleration of urbanization, urban landscape water bodies are facing serious eutrophication problems. Pollutants (such as nitrogen, phosphorus and other nutrients) carried by urban sewage discharge and surface runoff flow into landscape water bodies in large quantities. At the same time, the poor fluidity and weak self-purification ability of water bodies cause algae and other plankton to multiply in large numbers, resulting in reduced water transparency, deterioration of water quality, and odor, which seriously affects the beauty and function of landscape water bodies. This urgently requires a kind of urban landscape water eutrophication monitoring and purification equipment.

[0004] The existing urban landscape water eutrophication monitoring and purification equipment has the following disadvantages when in use:

[0005] First, the components are dispersed, resulting in poor coordination between monitoring data and purification operations during the eutrophication treatment process;

[0006] Secondly, a single purification method is often used, which results in poor purification effect. Furthermore, during purification, the agent cannot be released from multiple angles and is unevenly distributed in the water body, which affects the effect of eutrophication control of water bodies. At the same time, there is a lack of ability to adjust the depth of agent release, which may result in the agent not being released at the appropriate depth, making it impossible to effectively control the eutrophication conditions of water bodies at different depths. Summary of the invention

[0007] In view of the above-mentioned problems, the present invention provides a device for monitoring and purifying eutrophication of urban landscape water bodies.

[0008] The technical solution of the invention is: an urban landscape water eutrophication monitoring and purification device, comprising a mounting main pole, a mounting floating plate at the center of which is sleeved on the outside of the mounting main pole through a through mounting opening, a water purification component and an intelligent monitoring component arranged on the mounting floating plate; a plurality of planting areas distributed circumferentially at the periphery of the through mounting opening are arranged on the upper end of the mounting floating plate;

[0009] The water purification component includes a submerged plant rack arranged in each of the planting areas, a photoreaction pool arranged between two adjacent planting areas, and a plurality of drug release mechanisms arranged circumferentially on the side wall of the mounting floating plate;

[0010] The submerged plant frame is planted with submerged plant bodies, the bottom of the photoreaction tank is connected to a water pump through a water pump, and a drainage pipe is provided on the side wall of the photoreaction tank;

[0011] The drug release mechanism comprises a plurality of drug release discs mounted on the side wall of the mounting floating plate and having an addition port at the upper end, a plurality of drug release rods vertically disposed at the bottom end of each of the drug release discs, and a plurality of mounting rings uniformly disposed on the side wall of the drug release rods from top to bottom, a drug cartridge being connected to the addition port, and a plurality of release holes uniformly disposed on each of the mounting rings along the circumferential direction;

[0012] The intelligent monitoring component includes a monitor arranged at the bottom of each drug release disc, an underwater illuminometer arranged at the bottom of the mounting float, a PLC controller arranged at the upper end of the mounting main rod and electrically connected to the monitor and the underwater illuminometer, and a remote computer communicatively connected to the PLC controller.

[0013] Furthermore, a plurality of vertical sliding grooves are evenly arranged along the circumferential direction on the outer wall of the installation main rod, a linkage ring is arranged in the through installation opening, a hydraulic cylinder connected to the upper end of the linkage ring is arranged in each of the vertical sliding grooves, the linkage ring can slide along the outer wall of the installation main rod, and a plurality of auxiliary support rods are evenly arranged along the circumferential direction on the bottom end of the installation main rod.

[0014] Description: When the height of the installation float needs to be adjusted according to different water depths, the bottom end of the installation main rod is fixed to the bottom of the water. Several auxiliary support rods can increase the support points and enhance the stability of the overall structure. Then, through the extension or compression of each hydraulic cylinder, the linkage ring is driven to move up and down along the outer wall of the installation main rod. At the same time, the installation float will also move synchronously until the bottom end of the installation float floats on the water surface to adapt to different water levels.

[0015] Furthermore, the side wall of the mounting float plate is provided with a measuring mounting vertical plate connected to the drug release disc body in a one-to-one correspondence, and the side wall of the measuring mounting vertical plate is provided with a vertical sliding opening, and a sliding mounting seat with a C-shaped cross-section is connected to the vertical sliding opening through a sliding block, and the sliding mounting seat is clamped at the upper and lower ends of the drug release disc body, and a linear displacement sensor for monitoring the moving distance of the sliding block in the vertical direction is provided at the upper end of the vertical sliding opening, and the sliding block is driven to move up and down by an electric telescopic rod.

[0016] Description: When it is necessary to release medicine at different depths of the water body, the sliding block is driven by the electric telescopic rod to move downward in the vertical sliding port. At the same time, the moving height of the sliding block is detected by the linear displacement sensor, and each drug release rod at the bottom of the drug release disc will also move the same distance synchronously, so as to achieve the purpose of adjusting the depth of medicine release. According to the degree of eutrophication of the water body and the biological activity status, the release depth can be flexibly adjusted to cover different water layers, thereby improving the eutrophication control effect of the water body. At the same time, the drug release disc is movably connected through the C-shaped sliding mounting seat, which is convenient for cleaning and installation of the drug release disc and the drug release rod at its bottom, ensuring the normal progress of the medicine release work.

[0017] Furthermore, the submerged plant body is one or more of Vallisneria, Hydrilla, Potamogeton and Ceratophyllum.

[0018] Note: The above-mentioned submerged plants can absorb eutrophic substances such as nitrogen and phosphorus in the water body and convert them into nutrients needed for growth, effectively reducing the eutrophication level of the water body. In addition to the direct purification effect, submerged plants can also improve the transparency of the water body, inhibit the excessive reproduction of algae, improve water quality, and beautify the waterscape.

[0019] Furthermore, the installation circles on the side walls of the drug release rods are staggered, and a bulk mesh ring is provided outside each installation circle, and the inner diameter of the mesh of the bulk mesh rings distributed sequentially from top to bottom on each drug release rod gradually decreases.

[0020] Description: The staggered distribution of the mounting rings on the side walls of each drug release rod can increase the uniformity of drug addition. At the same time, with the setting of the bulk mesh ring, the drugs flowing out of the drug release rod can be dispersed again to ensure that the drugs are released from multiple angles and improve the uniformity of drug distribution in the water body. Since the water flow in the upper layer of the water body is faster, the larger mesh is conducive to rapid diffusion, and the flow rate of the bottom water body is slow, and the fine mesh ensures stable release. By limiting the inner diameter of the mesh of the bulk mesh ring distributed from top to bottom on each drug release rod to gradually decrease, it can adapt to different water layer environments, finely manage drug release, and avoid excessive or insufficient amounts.

[0021] Furthermore, a side wall of the bulk material net ring is provided with an annular recess, an annular spoiler is rotatably connected in the annular recess, and a plurality of spoiler rods are provided on the annular spoiler.

[0022] Description: When adding reagents, the annular spoiler in each annular notch will rotate through the driving force of the water flow, and the reagent and the water flow will be stirred through the spoiler rod, further improving the uniformity of the reagent distribution in the water body and improving the treatment effect of eutrophication of the water body.

[0023] Furthermore, the submerged plant rack includes a plurality of mounting branches radially distributed in each of the planting areas, a plurality of plant mounting rings provided on each of the mounting branches, and a plant mounting tube movably connected to the plant mounting rings in a one-to-one correspondence, and the submerged plant body is planted in the plant mounting tube.

[0024] Description: Several plant installation rings are set on the installation branch chain, and a plant installation cylinder with submerged plant bodies is movably placed in each plant installation ring. On the one hand, the submerged plant bodies can be used to absorb eutrophic substances such as nitrogen and phosphorus in the water body and convert them into nutrients required for growth, thereby effectively reducing the eutrophication level of the water body. On the other hand, it is convenient to regularly replace the submerged plant bodies, and the continuous use of fresh plants has a stronger ability to absorb nitrogen and phosphorus, thereby improving the water purification rate.

[0025] Furthermore, a sliding groove is provided on the inner wall of the planting area on the side opposite to the through mounting opening along the length direction, the mounting branch chain is slidably connected to the sliding groove through an adjusting block, and a fixed plug rod is provided on the mounting floating plate which passes through the sliding groove and extends into the adjusting block.

[0026] Description: Slidingly connect the mounting branch chain with the sliding groove on the inner wall of the planting area through the adjusting block, so as to adjust the distance between two adjacent mounting branch chains according to the growth condition of the main body of the submerged plant. Reasonable spacing ensures that the plant roots can fully stretch, avoids crowding, ensures that each plant receives appropriate amount of light, and improves the eutrophication treatment effect of the water body.

[0027] Furthermore, there are multiple underwater light meters, and the multiple underwater light meters are arranged at the bottom end of the mounting floating plate and correspond to the position of each planting area.

[0028] Description: By installing an underwater illuminance meter at the bottom of the mounting float and corresponding to each planting area, it is convenient to monitor the light intensity of the main body of the submerged plants in each planting area, so as to adjust the distance between two adjacent mounting branches to ensure that each plant receives the right amount of light.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] When the urban landscape water eutrophication monitoring and purification device of the present invention is used, the main body of the device is installed in the water area to be repaired by installing the main pole, and the monitoring components and purification components are centrally installed by installing the floating plate, so that the integration of the device can be realized, which is convenient for the maintenance and management of the staff; and when the water purification component treats the water body to be repaired, the photoreaction pool is used, and the photoreaction pool may decompose organic pollutants, algae and other eutrophication-related substances in the water body through photocatalytic reaction; the drug release mechanism can release chemical agents in a targeted manner to adjust the pH value of the water body and kill harmful microorganisms; the submerged plant body can absorb nutrients such as nitrogen and phosphorus in the water body, and at the same time provide a habitat for aquatic animals and improve the ecological environment of the water body. This combination of multiple methods can solve the problem of water eutrophication from multiple angles, making the purification effect more thorough;

[0031] The drug release mechanism of the invention drives the sliding block to move downward in the vertical sliding opening through the electric telescopic rod. At the same time, the moving height of the sliding block is detected by the linear displacement sensor, and each drug release rod located at the bottom of the drug release disc body will also move the same distance synchronously, so as to achieve the purpose of adjusting the depth of drug delivery, and improve the eutrophication treatment effect of the water body. At the same time, the staggered distribution of the mounting rings on the side walls of each drug release rod is limited, and the setting of the bulk mesh ring and the spoiler rod is combined to break up the drugs flowing out of the drug release rods again, ensuring that the drugs are released from multiple angles, and improving the uniformity of drug distribution in the water body.

[0032] When the submerged plant rack of the invention is in use, the mounting branch chain is slidably connected to the sliding groove on the inner wall of the planting area through the adjusting block, so that the distance between two adjacent mounting branch chains can be adjusted according to the growth status of the main body of the submerged plant. The reasonable spacing ensures that the plant root system can fully stretch and avoid crowding, ensuring that each plant receives an appropriate amount of light, thereby improving the eutrophication treatment effect of the water body.

[0033] The installation floating plate of the present invention can drive the linkage ring to move up and down along the outer wall of the installation main rod through the extension or compression of each hydraulic cylinder. At the same time, the installation floating plate will also move synchronously until the bottom end of the installation floating plate floats on the water surface to adapt to different water levels.

[0043] Example 1: Figure 1 , 2 As shown, a monitoring and purification device for eutrophication of urban landscape water bodies comprises a mounting main pole 1, a mounting floating plate 2 which is sleeved on the outside of the mounting main pole 1 through a through mounting opening 20 at the center, a water purification component 3 arranged on the mounting floating plate 2, and an intelligent monitoring component 4; the upper end of the mounting floating plate 2 is provided with four planting areas 21 which are distributed circumferentially at the periphery of the through mounting opening 20;

[0044] The water purification component 3 includes a submerged plant rack 30 arranged in each planting area 21, a photoreaction pool 31 arranged between two adjacent planting areas 21, and four drug release mechanisms 32 arranged along the circumferential direction on the side wall of the mounting floating plate 2;

[0045] A submerged plant body 300 is planted on the submerged plant rack 30, a water pump 310 is connected to a water pump 311 at the bottom of the photoreaction pool 31, and a drainage pipe 312 is arranged on the side wall of the photoreaction pool 31. The photoreaction pool 31 and the water pump 310 both adopt the existing technology. The photoreaction pool 31 is mainly used to degrade organic pollutants and nutrients such as nitrogen and phosphorus in the water through photocatalysis, thereby reducing the eutrophication level in the water body. The water pump 310 can adopt a QJF model high-pressure forced discharge multi-stage horizontal submersible pump;

[0046] The drug release mechanism 32 includes four drug release discs 321 installed on the side wall of the mounting float 2 and having a adding port 320 at the upper end, three drug release rods 322 arranged at the bottom end of each drug release disc 321 in the vertical direction, and five mounting rings 323 evenly arranged on the side wall of the drug release rods 322 from top to bottom, a drug cartridge 324 is connected to the adding port 320, and four release holes 3230 are evenly arranged on each mounting ring 323 along the circumferential direction;

[0047] The intelligent monitoring assembly 4 includes a monitor 40 disposed at the bottom of each drug release disc 321, an underwater illuminometer 41 disposed at the bottom of the mounting float 2, a PLC controller 42 disposed at the upper end of the mounting main rod 1 and electrically connected to the monitor 40 and the underwater illuminometer 41, and a remote computer in communication connection with the PLC controller 42, wherein the monitor 40, the underwater illuminometer 41, the PLC controller 42 and the remote computer all adopt existing technologies, the monitor 40 includes an online automatic monitor for total phosphorus water quality, an online monitor for ammonia nitrogen, an online automatic monitor for total nitrogen and a chlorophyll a detector, the underwater illuminometer 41 can adopt an underwater illuminometer of model TES-1334A, and the PLC controller 42 can adopt a PLC controller of model S7-1500 series;

[0048] The submerged plant body 300 is made of Vallisneria, Hydrilla, and Potamogeton. The submerged plants can absorb eutrophic substances such as nitrogen and phosphorus in the water body and convert them into nutrients required for growth, effectively reducing the eutrophication level of the water body. In addition to the direct purification effect, the submerged plants can also improve the transparency of the water body, inhibit the excessive reproduction of algae, improve water quality, and beautify the waterscape;

[0049] like Figure 3 , 4As shown, the mounting rings 323 on the side walls of the drug release rods 322 are staggered, and a bulk mesh ring 325 is provided outside each mounting ring 323, and the mesh inner diameter of the bulk mesh ring 325 on each drug release rod 322 and distributed sequentially from top to bottom gradually decreases. The staggered distribution of the mounting rings 323 on the side walls of the drug release rods 322 can increase the uniformity of drug addition. At the same time, with the setting of the bulk mesh ring 325, the drug flowing out of the drug release rod 322 is dispersed again to ensure that the drug is released from multiple angles and improve the uniformity of drug distribution in the water body. Since the water flow in the upper layer of the water body is faster, the larger mesh is conducive to rapid diffusion, and the flow rate of the bottom water body is slow, and the fine mesh ensures stable release. By limiting the mesh inner diameter of the bulk mesh ring 325 on each drug release rod 322 and distributed sequentially from top to bottom to gradually decrease, it is adapted to different water layer environments, and the drug release is finely managed to avoid excessive or insufficient.

[0050] An annular notch 326 is provided on the side wall of the bulk material net ring 325, and an annular spoiler 327 is rotatably connected in the annular notch 326. Four spoiler rods 328 are provided on the annular spoiler 327.

[0051] There are four underwater light meters 41, which are arranged at the bottom of the mounting float 2 and correspond to the position of each planting area 21. By installing the underwater light meters 41 at the bottom of the mounting float 2 and corresponding to the position of each planting area 21, it is convenient to monitor the light intensity of the submerged plant body 300 in each planting area 21, thereby adjusting the distance between two adjacent mounting branches 301 to ensure that each plant receives an appropriate amount of light.

[0052] Embodiment 2: This embodiment is different from Embodiment 1 in that the submerged plant body 300 is made of Vallisneria, Hydrilla, Potamogeton and Ceratophyllum.

[0053] Embodiment 3: This embodiment records a method for monitoring and purifying eutrophication of urban landscape water bodies, based on an equipment for monitoring and purifying eutrophication of urban landscape water bodies in Embodiment 1, comprising the following steps:

[0054] S1. Equipment installation

[0055] The bottom end of the main rod 1 is fixedly installed on the bottom of the water, so that the bottom end of the floating plate 2 floats on the upper end of the water surface;

[0056] S2. Monitoring of water eutrophication

[0057] The monitor 40 is used to monitor the total phosphorus content, ammonia nitrogen content, total nitrogen content and chlorophyll a concentration in the water body, and the underwater illuminometer 41 is used to monitor the light intensity of the submerged plant body 300 in each planting area 21. Then, the monitor 40 and the underwater illuminometer 41 upload the collected data signals to the remote computer. If a certain monitoring data exceeds the set safety limit, the remote computer will trigger an automatic response mechanism based on key information. At the same time, the command signal for adjusting parameters and changing the operation mode is sent back to the PLC controller 42, and the PLC controller 42 sends a control command to the water purification component 3, and the water purification component 3 operates according to the command of the PLC controller 42;

[0058] S3. Purification of eutrophic water

[0059] If a certain monitoring data exceeds the set safety limit, the water purification component 3 purifies the water according to the instruction of the PLC controller 42. At this time, the water pump 310 pumps the water to be treated into the photoreaction tank 31 through the water pumping pipe 311, and utilizes the photocatalytic effect of the photoreaction tank 31 to degrade the organic pollutants and nitrogen and phosphorus in the water. The treated water is discharged through the drain pipe 312. At the same time, the medicine in the medicine cartridge 324 is added to the medicine release disc 321 through the addition port 320, and enters each medicine release rod 322, and flows into the water through the release hole 3230 to purify the water. The submerged plant body 300 planted on the submerged plant rack 30 can absorb eutrophic substances such as nitrogen and phosphorus in the water and convert them into nutrients required for growth.

[0060] Embodiment 4: This embodiment differs from Embodiment 1 in that: Figure 1 As shown, a plurality of sliding vertical grooves 10 are evenly arranged along the circumferential direction on the outer wall of the installation main rod 1, and a linkage ring 200 is arranged in the through installation opening 20. A hydraulic cylinder 11 connected to the upper end of the linkage ring 200 is arranged in each sliding vertical groove 10. The linkage ring 200 can slide along the outer wall of the installation main rod 1. A plurality of auxiliary support rods 12 are evenly arranged along the circumferential direction on the bottom end of the installation main rod 1. When it is necessary to adjust the height of the installation floating plate 2 according to different water depths, the bottom end of the installation main rod 1 is fixedly installed on the bottom of the water. The supporting positions can be increased by several auxiliary support rods 12, thereby enhancing the stability of the overall structure. Then, the linkage ring 200 is driven to move up and down along the outer wall of the installation main rod 1 through the extension or compression of each hydraulic cylinder 11. At the same time, the installation floating plate 2 will also move synchronously until the bottom end of the installation floating plate 2 floats on the water surface, thereby adapting to different water levels.

[0061] The side wall of the installation floating plate 2 is provided with a measuring installation vertical plate 22 which is connected to the drug release disc 321 in a one-to-one correspondence. The side wall of the measuring installation vertical plate 22 is provided with a vertical sliding opening 23. A sliding mounting seat 24 with a C-shaped cross-section is connected to the vertical sliding opening 23 through a sliding block 220. The sliding mounting seat 24 is clamped at the upper and lower ends of the drug release disc 321. A linear displacement sensor 221 for monitoring the moving distance of the sliding block 220 in the vertical direction is provided at the upper end of the vertical sliding opening 23. The sliding block 220 is driven up and down by an electric telescopic rod 222. When it is necessary to release medicine at different depths of the water body, the sliding block 220 is driven vertically by the electric telescopic rod 222. The sliding opening 23 moves downward, and at the same time, the moving height of the sliding block 220 is detected by the linear displacement sensor 221, and each drug releasing rod 322 located at the bottom of the drug releasing disc 321 will also move the same distance synchronously, so as to achieve the purpose of adjusting the depth of drug delivery. According to the eutrophication degree of the water body and the biological activity status, the delivery depth can be flexibly adjusted to cover different water layers, thereby improving the eutrophication control effect of the water body. At the same time, the drug releasing disc 321 is movably connected through the sliding mounting seat 24 of the C-shaped structure, which is convenient for cleaning and installation of the drug releasing disc 321 and the drug releasing rod 322 at its bottom, thereby ensuring the normal progress of the drug delivery work.

[0062] Embodiment 5: This embodiment differs from Embodiment 3 in that:

[0063] In step S1, when the bottom end of the main rod 1 is fixedly installed on the bottom of the water, the supporting positions can be increased by using several auxiliary support rods 12. At the same time, when the height of the installation floating plate 2 needs to be adjusted according to different water depths, the linkage ring 200 is driven to move up and down along the outer wall of the main rod 1 through the extension or compression of each hydraulic cylinder 11. At the same time, the installation floating plate 2 will also move synchronously until the bottom end of the installation floating plate 2 floats on the water surface;

[0064] In step S3, when it is necessary to release medicine at different depths of the water body, the electric telescopic rod 222 drives the sliding block 220 to move downward in the vertical sliding opening 23. At the same time, the moving height of the sliding block 220 is detected by the linear displacement sensor 221, and each drug release rod 322 located at the bottom of the drug release disc 321 will also move the same distance synchronously, thereby achieving the purpose of adjusting the depth of drug release.

[0065] Embodiment 6: This embodiment differs from Embodiment 4 in that: Figure 5 , 6As shown in , 7, the submerged plant rack 30 is radially distributed in each planting area 21 with multiple mounting branches 301, multiple plant mounting rings 302 arranged on each mounting branch chain 301, and plant mounting tubes 303 movably connected to the plant mounting rings 302 in a one-to-one correspondence. The submerged plant body 300 is planted in the plant mounting tube 303, and a plurality of plant mounting rings 302 are arranged on the mounting branch chain 301, and a plant mounting tube 303 planted with the submerged plant body 300 is movably placed in each plant mounting ring 302. On the one hand, the submerged plant body 300 can be used to absorb eutrophic substances such as nitrogen and phosphorus in the water body and convert them into nutrients required for growth, thereby effectively reducing the eutrophication level of the water body. On the other hand, it is convenient to regularly replace the submerged plant body 300, and the continuous use of fresh plants has a stronger ability to absorb nitrogen and phosphorus, thereby improving the water purification rate;

[0066] A sliding groove 210 is provided along the length direction on the inner wall of the planting area 21 on the side opposite to the through installation opening 20. The installation branch chain 301 is slidably connected to the sliding groove 210 through the adjusting block 304, and the installation floating plate 2 is provided with a fixed plug-in rod 25 that penetrates the sliding groove 210 and extends into the adjusting block 304. The installation branch chain 301 is slidably connected to the sliding groove 210 on the inner wall of the planting area 21 through the adjusting block 304, so that the distance between two adjacent installation branch chains 301 can be adjusted according to the growth status of the submerged plant body 300. Reasonable spacing ensures that the plant roots are fully extended, avoids crowding, ensures that each plant receives an appropriate amount of light, and improves the eutrophication treatment effect of the water body.

[0067] Embodiment 7: This embodiment differs from Embodiment 5 in that:

[0068] In step S2, when the light intensity of the submerged plant body 300 in each planting area 21 is monitored by the underwater illuminance meter 41, when the light intensity of the submerged plant body 300 is insufficient, the mounting branch chain 301 is slidably connected to the sliding groove 210 on the inner wall of the planting area 21 through the adjustment block 304, so as to adjust the distance between two adjacent mounting branch chains 301, and a reasonable spacing ensures that the plant roots are fully extended.
