Description

Technical Field

[0001] The present invention belongs to the technical field of sewage discharge equipment, and specifically is a system and method for ecological restoration of water pollution in the Yangtze River Basin. Background Art

[0002] Landscape gardening uses engineering technology and artistic means in a certain area to create a natural environment and recreational space by transforming the terrain, or further building mountains, stacking stones, managing water, planting trees and flowers, constructing buildings and arranging garden paths. The pond in landscape gardening design is a beautiful landscape of landscape gardening.

[0003] However, the existing modular garden ponds do not have good sewage discharge devices, and there are often floating objects such as garbage in the ponds, which makes the water quality of the ponds worse. In addition, the silt at the bottom of the ponds becomes difficult to clean due to years of sedimentation, making the pond water unclear, which indirectly affects the garden environment.

[0004] Therefore, there is an urgent need for a pond sewage collection and drainage system for landscape gardening. The existing pond sewage collection and drainage system for landscape gardening adopts traditional maintenance methods such as large-scale dredging of the entire pond body when in use. It lacks specificity and cannot effectively remove dirt in specific areas. It only relies on a single suction method, and the sewage suction efficiency is low. Summary of the invention

[0005] In view of the above-mentioned problems, the present invention provides a pond sewage collection and discharge system and method for landscape gardening.

[0006] The technical solution of the present invention is: a pond sewage collection and drainage system applied to landscape gardens, comprising a pond body with a plurality of sewage collection tanks at the bottom, a sewage suction unit arranged in each of the sewage collection tanks, a sewage collection unit arranged in the pond body, and a sewage drainage well connected to the sewage collection unit;

[0007] The sewage suction unit comprises a sewage collection port arranged in the sewage collection tank, a fixing ring covering the sewage collection port, a rotating buckle cover rotatably connected to the upper end of the fixing ring, a sewage suction pipe circumferentially connected to the outer wall of the rotating buckle cover, a sewage suction head arranged at the end of the sewage suction pipe, a mounting vertical rod arranged on the rotating buckle cover and with the upper end extending above the water surface, and a rotating blade arranged at the upper end of the mounting vertical rod;

[0008] The sewage collection unit comprises a sewage collecting sub-pipe connected to the bottom of each sewage collecting port, a sewage collecting main pipe for connecting each of the sewage collecting sub-pipes, and a sewage pump arranged in the sewage well and connected to the sewage collecting main pipe;

[0009] A plurality of inclined mesh plates are respectively arranged on the left and right sides of the sub-sewage collecting pipe, a drainage pipe connected to the bottom of the inclined mesh plate is arranged on the side wall of the sub-sewage collecting pipe and located at the bottom of the inclined mesh plate, and a plurality of overflow ports connected to the drainage pipe one by one are arranged at the bottom of the pond body.

[0010] Furthermore, the sewage suction head is a trumpet-shaped structure, and a protective grille is provided at the opening of the sewage suction head.

[0011] Description: The trumpet-shaped suction head can more easily capture and suck in solid particles and impurities at the bottom of the pond, increase the coverage area of ​​the suction head, and thus improve the suction efficiency. The protective grille can prevent larger objects from entering the suction head, which can reduce wear and damage to the internal structure and ensure its service life.

[0012] Furthermore, the mounting vertical rod includes a fixed vertical rod arranged at the upper end of the rotating buckle cover, an adjusting vertical rod inserted into the upper end of the fixed vertical rod, the rotating blade is arranged at the upper end of the adjusting vertical rod, a plurality of horizontal sliding grooves and a plurality of vertical sliding grooves vertically distributed to the horizontal sliding grooves are arranged at the upper end of the inner wall of the fixed vertical rod, and sliding blocks are respectively arranged on the left and right sides of the bottom end of the adjusting vertical rod, and the sliding blocks can be slidably connected in each of the vertical sliding grooves and the horizontal sliding grooves.

[0013] Description: When it is necessary to adjust the height of the installation vertical rod according to the water depth in the pond body, the adjusting vertical rod is screwed to make the sliding block on the outer wall of the adjusting vertical rod slide in each vertical sliding groove, so as to adjust the height of the adjusting vertical rod and ensure that the rotating blade is located on the water surface. When the sliding block is adjusted to a suitable height, the sliding block is screwed to engage in the horizontal sliding groove of the corresponding height to ensure that the rotating buckle cover and the sewage suction pipe are rotated under the action of wind, so that the sewage in various places of the sewage collection port can be discharged in time. Since it can be flexibly adjusted according to the water depth and the equipment can rotate stably under the action of wind, this helps the sewage collection port to comprehensively collect sewage in various places.

[0014] Furthermore, a plurality of magnetic sheets are provided in the horizontal sliding groove and the vertical sliding groove, and a metal shell is provided on the outer wall of the sliding block.

[0015] Note: When the sliding block is engaged in the horizontal sliding groove of the corresponding height, the outer wall of the sliding block is fixedly adsorbed by the corresponding magnetic suction sheet, thereby increasing the stability of the connection between the adjustment vertical rod and the fixed vertical rod.

[0016] Specifically, the diameter of the main sewage collecting pipe is larger than the diameter of the sub-sewage collecting pipe, and the wall thickness of the main sewage collecting pipe is 1.2-1.5 times the wall thickness of the sub-sewage collecting pipe.

[0017] Note: The main sewage pipe has a larger diameter and can accommodate more sewage flow. Because in the entire sewage system, the sewage from each sub-sewage pipe will eventually be collected in the main sewage pipe. The larger pipe diameter can ensure that the sewage from each sub-sewage pipe can flow in smoothly, avoiding sewage overflow or poor flow.

[0018] Furthermore, an anti-pollution cover is provided at the upper end of each overflow port, and the anti-pollution cover includes a fixing ring provided at the upper end of the overflow port, a folding cylinder provided at the upper end of the fixing ring, and a sealing cover plate provided at the upper end of the folding cylinder. A plurality of overflow holes are provided on the folding cylinder, and the overflow hole is a trumpet-shaped structure with the side with a larger opening located on the inner side of the folding cylinder.

[0019] Description: When the water discharged from each drain pipe flows out through the overflow port, the water flow will push the folding cylinder open and move out from each overflow hole. At the same time, since the overflow hole is a trumpet-shaped structure with the larger opening on the inner side of the folding cylinder, the water can pass smoothly, reducing the vibration or shaking caused by the impact of the water flow, making the entire overflow port related structure including the folding cylinder more stable and reliable. At the same time, due to the impact force of the water flow, the dirt at the overflow hole is washed away. When there is no water flowing out of the overflow port, the folding cylinder is in a folded state, which can prevent the overflow hole from being blocked.

[0020] Furthermore, a maintenance ladder is provided in the sewage well, and a deodorant spray unit is provided at the sewage well. The deodorant spray unit includes a liquid storage tank arranged outside the sewage well, a spray pipe arranged along the inner wall of the sewage well and connected to the liquid storage tank, a liquid pump arranged at the connection between the liquid storage tank and the spray pipe, and a spray column arranged on the spray pipe and inclined downward.

[0021] Description: The maintenance ladder allows workers to enter the sewage well for inspection, maintenance and cleaning, thereby improving work efficiency and enhancing safety. The deodorant spray unit sprays deodorant into the sewage well, which can effectively remove the foul smell in the sewage well and improve the surrounding environment. When the deodorant spray unit is in use, the deodorant in the liquid storage tank is evenly sprayed into the sewage well from all directions through the various spray columns on the spray pipe through the liquid pump, and reacts quickly and fully with the odor source in the sewage well, thereby more effectively removing the odor.

[0022] Furthermore, a Y-shaped mounting frame is provided at the opening of the spray column, and a porous dispersion sheet is rotatably connected to the center of the Y-shaped mounting frame.

[0023] Description: When the deodorant is sprayed out through each spray column, it will impact the rotation of each dispersion piece. The rotation of the dispersion piece will disperse the deodorant in a larger range. The porous dispersion piece will break up the deodorant into more and smaller droplets, thereby increasing the contact area between the deodorant and the air and the substances in the sewage well. This helps to improve the efficiency of deodorization, eliminate the odor in the sewage well more quickly, and improve the surrounding environment.

[0024] The present invention also provides a method for collecting and discharging sewage from a pond applied to landscape gardening. Based on the above-mentioned system for collecting and discharging sewage from a pond applied to landscape gardening, the method comprises the following steps:

[0025] S1. When the bottom of the pond needs to be discharged, the sewage in the corresponding sewage collection tank is sucked into the rotating buckle cover through the sewage suction head, and then collected into the sewage collection main pipe through the sub-collection pipe. When there is wind, the rotating blades drive the installation vertical rod to rotate under the action of wind. At this time, the various sewage suction pipes located on the outer wall of the rotating buckle cover rotate, so as to fully absorb the surrounding sewage;

[0026] S2. When the waste in each sub-collecting pipe is collected in the main collecting pipe, it is pumped into the sewage well by the sewage pump for collection, and finally, it can be removed from the sewage well;

[0027] S3. When the sewage falls from the sub-collecting pipe, it is filtered through each inclined mesh plate, so that part of the water in the sewage falls into the drain pipe, and the filtered solid sewage falls into the main sewage collecting pipe. When part of the water in the sewage falls into the drain pipe, it flows back to the main body of the pond through the corresponding overflow port.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] (1) The present invention provides a pond sewage collection and drainage system and method for landscape gardening. When the system is in use, a plurality of sewage collection tanks are arranged at the bottom of the pond body, and a sewage suction unit is arranged at each sewage collection tank. The sewage in the corresponding sewage collection tank is pumped to the sewage collection unit for collection by the sewage suction unit, and then sucked into the sewage well by a pump. The arrangement of the plurality of sewage collection tanks, the sewage suction unit, the sewage collection unit and the sewage well forms a complete sewage collection and drainage system. Compared with the traditional maintenance method of large-scale dredging of the entire pond body, this sewage collection and drainage system can clean the sewage in a targeted manner. Since the sewage can be pumped away in time, the deposition of sewage in the pond is reduced, thereby reducing the frequency of large-scale dredging of the pond.

[0030] (2) In order to ensure the suction efficiency of the sewage suction unit, while the sewage suction head is sucking the sewage, the rotating blades under the action of wind can also drive the installation vertical rod to rotate. At this time, the various sewage suction pipes located on the outer wall of the rotating buckle cover rotate, so as to fully suck the surrounding sewage. The sewage suction effect is greatly improved through the double suction effect. When it is necessary to adjust the height of the installation vertical rod according to the water depth in the pond body, the adjusting vertical rod is screwed to make the sliding block on the outer wall of the adjusting vertical rod slide in each vertical sliding groove, so as to adjust the height of the adjusting vertical rod and ensure that the rotating blade is located on the water surface. When the sliding block is adjusted to a suitable height, the sliding block is screwed and engaged in the horizontal sliding groove of the corresponding height. Since it can be flexibly adjusted according to the water depth and the equipment can rotate stably under the action of wind, it is helpful for the sewage collection port to comprehensively collect sewage from various places.

DETAILED DESCRIPTION

[0041] In order to further understand the content of the present invention, the present invention is described in detail below through examples.

[0042] Example 1: Figure 1 , 2 As shown, a pond sewage collection and drainage system used in landscape gardening includes a pond body 1 with 9 sewage collection tanks 10 at the bottom, a sewage suction unit 2 arranged in each sewage collection tank 10, a sewage collection unit 3 arranged in the pond body 1, and a sewage discharge well 4 connected to the sewage collection unit 3;

[0043] The sewage suction unit 2 includes a sewage collection port 20 arranged in the sewage collection tank 10, a fixing ring 21 covering the sewage collection port 20, a rotating buckle cover 22 rotatably connected to the upper end of the fixing ring 21, a sewage suction pipe 23 circumferentially connected to the outer wall of the rotating buckle cover 22, a sewage suction head 24 arranged at the end of the sewage suction pipe 23, a mounting vertical rod 25 arranged on the rotating buckle cover 22 and extending above the water surface at the upper end, and a rotating blade 26 arranged at the upper end of the mounting vertical rod 25, wherein the sewage suction head 24 and the rotating blade 26 are both made of existing technology, for example, the sewage suction head 24 can adopt the NewPig PIL201 universal sewage suction pillow, and the sewage suction head 24 can adopt the blade of model 4.XMW-6.XMW;

[0044] The sewage collecting unit 3 includes a sub-sewage collecting pipe 30 connected to the bottom end of each sewage collecting port 20, a sewage collecting main pipe 31 for connecting each sub-sewage collecting pipe 30, and a sewage pump 32 arranged in the sewage well 4 and connected to the sewage collecting main pipe 31, wherein the sewage pump 32 adopts the existing technology, for example, a WQ type sewage pump can be adopted;

[0045] Two inclined mesh plates 300 are respectively provided on the left and right sides of the sub-collecting sewage pipe 30, and a drainage pipe 301 connected to the bottom of the inclined mesh plate 300 is provided on the side wall of the sub-collecting sewage pipe 30, and 9 overflow ports 11 connected to the drainage pipe 301 are provided at the bottom of the pond body 1.

[0046] like Figure 3 As shown, the sewage suction head 24 is a trumpet-shaped structure, and a protective grille 240 is provided at the opening of the sewage suction head 24;

[0047] like Figure 4 , 5 6, the installation vertical rod 25 includes a fixed vertical rod 250 arranged at the upper end of the rotating buckle cover 22, an adjusting vertical rod 251 plugged into the upper end of the fixed vertical rod 250, and a rotating blade 26 is arranged at the upper end of the adjusting vertical rod 251. The upper end of the inner wall of the fixed vertical rod 250 is provided with three horizontal sliding grooves 252 and eight vertical sliding grooves 253 vertically distributed with the horizontal sliding grooves 252. The left and right sides of the bottom end of the adjusting vertical rod 251 are respectively provided with sliding blocks 254, and the sliding blocks 254 can be slidably connected in each vertical sliding groove 253 and the horizontal sliding groove 252. Since it can be flexibly adjusted according to the water depth and the equipment can be stably rotated under the action of wind, it is helpful for the sewage collection port 20 to comprehensively collect sewage from all places;

[0048] 40 magnetic sheets 255 are provided in the horizontal sliding groove 252 and the vertical sliding groove 253, and a metal shell 256 is provided on the outer wall of the sliding block 254. When the sliding block 254 is clamped in the horizontal sliding groove 252 of the corresponding height, the outer wall of the sliding block 254 is fixedly adsorbed by the corresponding magnetic sheet 255, thereby increasing the stability of the connection between the adjustment vertical rod 251 and the fixed vertical rod 250. The magnetic sheet 255 and the metal shell 256 are both made of existing technology. For example, the magnetic sheet 255 can be made of SAV 244.06-500-A electromagnetic clamping plate.

[0049] The diameter of the sewage collecting main pipe 31 is larger than that of the sub-sewage collecting pipes 30, and the wall thickness of the sewage collecting main pipe 31 is 1.2 times the wall thickness of the sub-sewage collecting pipes 30. The sewage collecting main pipe 31 has a larger diameter and can accommodate more sewage flow, because in the entire sewage discharge system, the sewage from each sub-sewage collecting pipe 30 will eventually be collected in the sewage collecting main pipe 31. The larger diameter can ensure that the sewage from each sub-sewage collecting pipe 30 flows in smoothly, avoiding sewage overflow or poor flow.

[0050] Embodiment 2: This embodiment differs from Embodiment 1 in that the diameter of the sewage collecting main pipe 31 is larger than the diameter of the sewage collecting sub-pipe 30 , and the wall thickness of the sewage collecting main pipe 31 is 1.5 times the wall thickness of the sewage collecting sub-pipe 30 .

[0051] Embodiment 3: This embodiment describes a method for collecting and discharging sewage from a pond applied to landscape gardening. Based on the embodiment 2, a system for collecting and discharging sewage from a pond applied to landscape gardening includes the following steps:

[0052] S1. When the bottom of the pond body 1 needs to discharge sewage, the sewage in the corresponding sewage collection tank 10 is sucked into the rotating buckle cover 22 through the sewage suction head 24, and collected into the sewage collection main pipe 31 through the sub-sewage collection pipe 30. When there is wind, the rotating blades 26 drive the installation vertical rod 25 to rotate under the action of wind. At this time, the sewage suction pipes 23 located on the outer wall of the rotating buckle cover 22 rotate, so as to fully absorb the surrounding sewage;

[0053] S2. After the waste in each sub-collecting pipe 30 is collected in the main collecting pipe 31, it is pumped into the sewage well 4 by the sewage pump 32 for collection, and finally, it can be removed from the sewage well 4;

[0054] S3, when the sewage falls from the sub-collecting pipe 30, it is filtered by each inclined mesh plate 300, so that part of the water in the sewage falls into the drain pipe 301, and the filtered solid sewage falls into the sewage collecting main pipe 31. When part of the water in the sewage falls into the drain pipe 301, it flows back to the pond body 1 through the corresponding overflow port 11;

[0055] S4. When it is necessary to adjust the height of the installation vertical rod 25 according to the water depth in the pond body 1, the vertical rod 251 is screwed to make the sliding block 254 on the outer wall of the adjusting vertical rod 251 slide in each vertical sliding groove 253, so as to adjust the height of the adjusting vertical rod 251 and ensure that the rotating blade 26 is located on the water surface. When the sliding block 254 is adjusted to a suitable height, the sliding block 254 is screwed to engage in the horizontal sliding groove 252 of the corresponding height to ensure that the rotating buckle cover 22 and the sewage suction pipe 23 rotate under the action of wind, so that the sewage at various places of the sewage collection port 20 can be discharged in time.

[0056] Embodiment 4: This embodiment differs from Embodiment 2 in that:

[0057] like Figure 7 , 8As shown, an anti-fouling cover 110 is provided at the upper end of each overflow port 11, and the anti-fouling cover 110 includes a fixing ring 111 arranged at the upper end of the overflow port 11, a folding cylinder 112 arranged at the upper end of the fixing ring 111, and a blocking cover plate 113 arranged at the upper end of the folding cylinder 112. The folding cylinder 112 is provided with 12 overflow holes 114, and the overflow holes 114 are trumpet-shaped structures with a larger opening on the inner side of the folding cylinder 112. When the water discharged from each drain pipe 301 flows out through the overflow port 11, the water flow will push the folding cylinder 112 open and move out from each overflow hole 114. At the same time, since the overflow hole 114 is a trumpet-shaped structure with a larger opening on the inner side of the folding cylinder 112, the water flow can pass smoothly, reducing the vibration or shaking caused by the impact of the water flow. The foldable cylinder 112 is in a folded state when no water flows out of the overflow port 11, so that the overflow hole 114 is prevented from being blocked. The main body of the foldable cylinder 112 is made of soft plastic, such as soft PVC polyvinyl chloride, which has a certain flexibility and can realize the folding function, while the connecting part of the foldable cylinder or the part that needs to be fixed in shape is made of hard plastic, such as ABS acrylonitrile-butadiene-styrene copolymer. This combined structure can ensure the deformation ability of the foldable cylinder under the impact of water flow, and can also ensure the stability of its overall structure to prevent excessive deformation.

[0058] Embodiment 5: This embodiment differs from Embodiment 3 in that:

[0059] In step S3, when the water discharged from each drain pipe 301 flows out through the overflow port 11, the water flow will push open the folding tube 112 and move out from each overflow hole 114. At the same time, since the overflow hole 114 is a trumpet-shaped structure with a larger opening on the inner side of the folding tube 112, the water can pass smoothly. When no water flows out of the overflow port 11, the folding tube 112 is in a folded state, which can prevent the overflow hole 114 from being blocked.

[0060] Embodiment 6: This embodiment differs from Embodiment 4 in that:

The maintenance ladder 40 facilitates the staff to enter the sewage well 4 for inspection. Maintenance and cleaning work, improve work efficiency and enhance safety. The deodorant spraying unit 41 sprays the deodorant into the sewage well 4, which can effectively remove the foul smell in the sewage well 4 and improve the surrounding environment. When the deodorant spraying unit 41 is in use, the deodorant in the liquid storage tank 410 is sprayed uniformly from all directions into the sewage well 4 through the various spraying columns 413 on the spraying pipe 411 by the liquid pump 412, and reacts quickly and fully with the odor source in the sewage well 4, thereby more effectively removing the odor;

[0062] A Y-shaped mounting frame 414 is provided at the opening of the spray column 413, and a porous dispersion sheet 415 is rotatably connected at the center of the Y-shaped mounting frame 414. When the deodorant is sprayed through each spray column 413, it will impact the rotation of each dispersion sheet 415. The rotation of the dispersion sheet 415 will disperse the deodorant in a larger range. The porous dispersion sheet 415 will break up the deodorant into more and smaller droplets, thereby increasing the contact area between the deodorant and the air and the substances in the sewage well, which helps to improve the deodorization efficiency, eliminate the odor in the sewage well 4 more quickly, and improve the surrounding environment. Among them, the liquid pump 412 adopts the existing technology, for example, a pneumatic liquid pump with model HD-E2-V+SS304 can be used.

[0063] Embodiment 7: This embodiment differs from Embodiment 5 in that: it also includes step S5;

[0064] S5. The maintenance ladder 40 facilitates the staff to enter the sewage well 4 for inspection, maintenance and cleaning. When the sewage well 4 needs to be deodorized, the deodorant in the liquid storage tank 410 is evenly sprayed into the sewage well 4 from all directions through the various spray columns 413 on the spray pipe 411 by the liquid pump 412, and reacts quickly and fully with the odor source in the sewage well 4, thereby removing the odor more effectively.

9. A method for collecting and discharging sewage from a pond used in landscape gardening, based on a system for collecting and discharging sewage from a pond used in landscape gardening according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1. When the bottom of the pond body (1) needs to discharge sewage, the sewage in the corresponding sewage collecting tank (10) is sucked into the rotating buckle cover (22) through the sewage suction head (24), and then collected into the sewage collecting main pipe (31) through the sewage collecting sub-pipe (30). When there is wind, the rotating blades (26) drive the installation vertical rod (25) to rotate under the action of the wind. At this time, the sewage suction pipes (23) located on the outer wall of the rotating buckle cover (22) rotate, so as to fully absorb the surrounding sewage; S2. After the waste in each sub-collecting pipe (30) is collected in the main collecting pipe (31), it is pumped into the sewage well (4) by the sewage pump (32) for collection, and finally, it is removed from the sewage well (4); S3. When the waste falls from the sewage collecting sub-pipe (30), it is filtered by each inclined mesh plate (300), so that part of the water in the waste falls into the drainage pipe (301), and the filtered solid waste falls into the sewage collecting main pipe (31). When part of the water in the waste falls into the drainage pipe (301), it flows back into the pond body (1) through the corresponding overflow port (11).
