Description

Technical Field

[0001] The invention belongs to the technical field of channel pollution cleaning, and in particular relates to an array-type wall-attached fixed pollution cleaning system. Background Art

[0002] As a common water conveyance structure, channels are characterized by simple construction and stable operation. However, there are still water areas of varying lengths from the main canal branch and outlet gate to the gate, also known as the cecal segment. The friction of the mainstream drives the circulation and lateral diffusion of the cecal segment. At the same time, there are also problems such as siltation caused by dry and wet dust and drainage ditch mud entering the channel, and the large-scale breeding, aggregation and sedimentation of benthic organisms such as algae and freshwater shells. In addition, since there are no pollution interception facilities, suspended dirt is prone to accumulation in the cecal segment, which seriously affects the water environment quality of the branch and outlet, and affects the water conveyance of the channel.

[0003] In order to clean the cecal segment, the current method of stopping water supply to the channel for cleaning is often adopted. However, stopping water supply to the channel for cleaning takes a certain amount of time, which will reduce the water supply guarantee rate and affect the operation of the channel.

[0004] Moreover, when stopping water flow to the channel for cleaning, on the one hand, the existing equipment has low cleaning efficiency and is easy to pollute the main stream water body; on the other hand, the existing cleaning technology is not suitable for the hydraulic ecology and boundary conditions of the main channel outlet, and has low cleaning efficiency and high energy consumption. At present, there is no suitable green cleaning technology and special equipment, and it is impossible to achieve high-efficiency non-stop water cleaning. Therefore, it is urgent to study the flow characteristics, growth and deposition conditions of suspended pollutants near the outlet, and to carry out the research and development of silt removal system technology and equipment in the static water area before the channel water discharge gate with the goal of non-stop water flow, environmental protection, and efficient real-time cleaning. This has important theoretical and practical significance for realizing green and intelligent cleaning, comprehensively improving water quality, and improving the technical design and safe operation of the water delivery system.

DETAILED DESCRIPTION

[0024] In view of the problem that the existing equipment cannot clean the sludge at the bottom of the canal cecum section without stopping the water flow, the present invention provides a cleaning system for the sludge at the bottom of the canal cecum section without stopping the water flow. The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Embodiment 1: This embodiment provides an array type wall-mounted fixed cleaning system, such as Figure 1 and Figure 2 As shown, the sewage cleaning system includes a sewage cleaning pipe network system, a monitoring unit 4, a pumping device 5, a suction device 6 and a control center 7. The monitoring unit, the pumping device, the suction device and the water-waste separation device are respectively connected to the control center. The sewage cleaning pipe network system includes a sewage cleaning pipe network 3 and a pipe network fixing frame 2. The sewage cleaning pipe network is installed on the wall of the cecum section of the channel 1 through the pipe network fixing frame. Figure 3-5 As shown, the sewage cleaning pipe network includes a primary main pipe 31, which is connected to the pumping device 5 and the suction device 6 respectively, and is connected to a plurality of secondary main pipes 32, each of which is connected to a plurality of tertiary main pipes 33, each of which is connected to a plurality of quaternary main pipes 34, and each of which is connected to a plurality of branch pipes 35 at the end of each quaternary main pipe, and a sewage cleaning pipe 36 at the end of each branch pipe, and the pipe opening of the sewage cleaning pipe is installed on the channel wall so that it is arranged horizontally or vertically with the channel wall, so as to facilitate the disturbance of the sewage on the channel wall through the sewage cleaning pipe. In the specific arrangement, the sewage cleaning pipes adjacent or separated in the same area can be arranged alternately in a manner of being perpendicular to the channel wall and parallel to the channel wall.

[0026] The monitoring unit 4 includes a plurality of monitoring modules 41, which are evenly mounted on the pipe network fixing frame and are used to monitor the sludge content of the channel wall in different areas of the cecum section of the channel and transmit the monitoring information to the control center. Figure 7 As shown, the monitoring unit monitors the sludge content on the channel wall in its monitoring area and transmits the monitoring information to the control center, which determines whether the channel needs to be cleaned.

[0027] If the sludge content exceeds the set value, the control center 7 sends a command to first open the valve and the pumping device to inject water into the channel wall through the pipe network, and use the impact of water to disturb the sludge at the bottom of the channel to turn over the sludge; then open the suction device to allow each sewage cleaning pipe to suck the water and sewage step by step and send the sucked water and sewage to the water-sewage separation system for separation; after the sewage is treated by the water-sewage separation system, the clean water is transported to the channel through the drainage pipe 10; the sewage is sent to the sludge treatment program through the sewage conveying pipe 12, and the sludge can be used as concentrated fertilizer after treatment; at the same time, the water-sewage separation system transmits the working data to the control center, and the control center controls the monitoring unit to measure the sludge content; when the monitoring unit detects that the sludge content in the channel is lower than the set value, the control center sends a standby command, first closes the suction device and the pumping device, and then closes the valve and the water-sewage separation system to complete a sewage cleaning task.

[0028] If the silt content in the channel does not exceed the set value and no cleaning is required, the control center will send a standby command to other equipment except the monitoring unit and no cleaning work will be performed.

[0029] Embodiment 2: This embodiment provides another array-type wall-mounted fixed sewage cleaning system. The difference between this system and embodiment 1 is that the pipe network system of this embodiment is a mutually independent dual-channel pipe network, which includes a water injection pipe network system and a suction pipe network system. Both pipe networks are installed on the channel wall through the same pipe network fixing frame, and the first-level pipes and the first-level pipes of the water injection pipe network and the suction pipe network are arranged in parallel. Figure 6 As shown, the first-level water injection main of the water injection network is connected to the pumping device and then connected to the upper water layer upstream of the channel through a pipeline; the first-level suction main of the suction network is connected to the suction device.

[0030] When the monitoring unit detects that the sludge content exceeds the standard, the sewage cleaning system is turned on, the control unit controls the valve to open, and at the same time controls the pumping device to pump the upper clean water upstream of the channel to the sewage cleaning pipe through various levels of pipes, thereby disturbing the sludge near each sewage cleaning pipe; then the pumping device is turned off and the suction device is turned on. The suction device extracts the disturbed sewage through the first-level suction main pipe, and then sends it to the water-waste separation device for separating the sucked water and sewage.

[0031] This embodiment realizes water injection and suction respectively by setting up independent double pipe networks, so that the two processes will not affect each other, which can significantly improve the water sewage suction effect.

[0032] Embodiment 3: In the above embodiment, since the pressure of the water flow pumped by the pumping device is weakened after being transmitted through the first-stage main pipe, various levels of main pipes and branch pipes and reaches the final-stage sewage cleaning pipe, its disturbing effect on the sludge is limited; at the same time, since the impact of the final-stage sewage cleaning pipe on the sludge near the pipe mouth is a linear impact, it eventually forms a point impact on the sludge on the channel wall, the disturbance area is small, and the range of sludge stirring is small, which is not conducive to subsequent suction.

[0033] In order to solve this problem, this embodiment is improved on the basis of Embodiment 1 and Embodiment 2. Specifically, a rotary pressurized wide-angle nozzle is installed at the pipe mouth of the terminal sewage cleaning pipe. Through the pressure of the rotary pressurized wide-angle nozzle, the sludge at the pipe mouth of the sewage cleaning pipe is rotated and sprayed, so that the point impact point formed at the outlet of the sewage cleaning pipe is expanded into an annular impact surface, further improving the disturbance effect and being more conducive to the subsequent sludge suction work.

[0034] Embodiment 4: Since the first-level main pipe pumps water to the subordinate pipes at all levels at the same time, it targets the entire pipe network system; and due to the terrain and environmental problems, the sludge accumulation in different areas of the channel cecum section is different. Some areas will have less sludge and temporarily do not need to be dredged, while some areas will have more sludge and need to be dredged. If the pipes at all levels are pumped at the same time, there will not only be a waste of resources, but also a large area of ​​channel wall sludge will be disturbed by the impact of water, resulting in large-scale turbid water, which is not conducive to ensuring the quality of water supply.

[0035] In order to solve the above problems, this embodiment is improved on the basis of embodiment 1, and provides another implementation method of the array-type wall-mounted fixed cleaning system, which is different from embodiment 1 in that: Figure 5 As shown, on the basis of Example 1, a control switch 8 is installed on each three-level main pipe, and the control switch is connected to the control center 7, and the opening and closing of the three-level main pipe in the area are controlled by the control switch. When the monitoring unit of a certain area detects that there is a lot of sludge in the area and pollution cleaning work is required, the monitoring unit transmits the monitoring signal to the control center, and the control center controls the valve, pumping device and the control switch of the three-level main pipe in the area to open, and pump water to the pipe network in the area, while the areas where the control switches of other areas are not turned on do not pump water, thereby realizing regional water pumping, which can avoid the impact of water pumping on the water body in the whole area.

[0036] Example 5: On the basis of Example 4, for a pipe network system in which the water injection network and the suction network are independent of each other, control switches are installed on the three-level water injection pipe and the three-level suction pipe respectively, so that independent control of the two pipe networks can be achieved, and water injection and suction in different areas can also be achieved to ensure the progress of sewage cleaning work.

[0037] Embodiment 6: In the sewage cleaning network, since the pumping device is aimed at the entire pipe network system, the pumping device diverts the water through the first-level main pipe, the second-level main pipe, the third-level main pipe and the fourth-level main pipe in sequence before it can impact the sludge on the channel wall through the terminal sewage cleaning pipe. Due to the step-by-step transmission of each level of pipeline, the pressure of the pumped water becomes smaller when it reaches the terminal sewage cleaning pipe, affecting the final sewage cleaning effect.

[0038] In view of the above problems, this embodiment provides a diversion device in the three-level main pipe to control the water flow of the three-level main pipe, thereby achieving the effect of cleaning mud and dirt in different areas. Figure 7 and Figure 8 As shown, the diverter device includes a diverter wheel 17, a diverter valve 18 and a diverter plate 16, wherein the diverter wheel 17 is installed on the water-incoming direction of the three-stage main pipe, the diverter plate 16 is arranged on the side of the diverter wheel away from the water-incoming direction and is fixedly connected to the main pipe wall, dividing the pipeline into an upper branch pipe 21 and a lower branch pipe 22, wherein the diverter valve is installed on the end of the diverter plate facing the diverter wheel, and the specific diverter valve includes an upper valve plate 19 and a lower valve plate 20, wherein the angle between the upper valve plate and the lower valve plate is 60°.

[0039] When the water in the pipeline flows normally, the lower valve plate of the diverter valve contacts the lower pipe wall of the pipeline to block the water flowing to the lower part of the pipeline, so that the water flows through the upper channel and enters the upper branch pipe; when the water pressure of the upper branch pipe gradually increases, the water pushes the upper valve plate to contact the upper part of the pipe wall to block the upper water flow, and the water in the pipeline flows out of the lower branch pipe. The alternating changes in the pressure on the upper and lower valve plates of the diverter valve adaptively adjust the different water flow directions according to the water flow, thereby realizing the diversion of the water flow of the upper and lower branches.

[0040] Embodiment 7: The sewage cleaning pipes in the above embodiments are all conventional pipe openings. Although they can suck the sludge stirred up in the surrounding area, they can only suck the dirt in a small area nearby, and there are problems of insufficient sewage cleaning capacity and limited sewage suction area.

[0041] In response to the above problems, Fig. 9 As shown in Figure 10, in this embodiment, a rotary suction head 23 is installed at the pipe opening of the sewage cleaning pipe. The rotary suction head is a hollow truncated cone structure with two ends connected, which includes an upper interface, a sewage suction port, and a cylinder wall connecting the upper interface and the sewage suction port. The upper interface is connected to the terminal pipe opening of the sewage cleaning pipe, and the diameter of the upper interface 24 is smaller than the diameter of the lower sewage suction port 25. Under the action of the suction force, the sewage enters the sewage cleaning pipe in a rotating manner in the rotary suction head, which can not only expand the sewage suction area and increase the suction force, but also avoid clogging and improve the sewage suction effect.

[0042] It should be understood that the above specific embodiments of the present invention are only used for illustrative explanation or explanation of the principle of the present invention, and do not constitute a limitation of the present invention. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. For example, in order to achieve the same purpose as in Example 7, it is not excluded that on the basis of other embodiments, a core tube is set at the end of the cleaning pipe, so that a convex-concave connection is set between the two, so that the two can rotate but cannot axially extend. And a regional transverse tube is vertically fixed at the end of the core tube, and the regional transverse tube forms a T-shaped structural relationship with the core tube, and the regional transverse tube is connected with the core tube inner cavity. The two ends of the regional transverse tube are closed, but at least one water hole is opened at the front and rear sides near the two ends, that is, the water holes on both sides are respectively located on one side of one end of the regional transverse tube and the other side of the other end. When the cleaning pipe discharges water outward, the water flow is discharged from the two water holes at the two ends of the regional transverse tube. Because the drainage is under pressure, the regional transverse tube and the core tube are rotated, so that the drainage area is changed from a static point to a dynamic line or surface. Furthermore, the lengths of the core pipes of adjacent cleaning pipes can be different, so that the adjacent regional transverse pipes are no longer at the same height.
