Description

[0002] In the operation and development of modern cities, the municipal pipeline system plays a vital role, shouldering key functions such as sewage discharge and rainwater diversion. However, with the continuous expansion of urban scale, the continuous growth of population and the increasing frequency of various industrial activities, municipal pipelines are facing many severe challenges, among which the problem of pipeline siltation is particularly prominent. In daily life, a large amount of sewage carrying mud, kitchen waste, hair and other debris is continuously discharged into the sewage pipe. These debris are slowly deposited inside the pipe with the water flow. Over time, they gradually accumulate at the bottom of the pipe, the corners of the pipe wall, the change of pipe diameter and other parts to form a silt layer, which will cause the pipe to be blocked.

Manual inspections are inefficient and it is difficult to accurately and timely detect siltation inside the pipeline. Often, dredging work is urgently arranged only when there are obvious signs of blockage in the pipeline, such as sewage overflowing on the road surface, backflow in rainwater wells, etc. This passive maintenance mode not only consumes a lot of manpower, material and financial resources, but also during the dredging process, workers need to enter the narrow, humid, and harmful gas-filled pipelines to work, facing great safety risks, such as poisoning, suffocation, collapse and other accidents.

[0020] The present invention provides a municipal pipeline silt collection and desilting early warning integrated device as follows: First embodiment: Combination Figure 1-Figure 4, the present embodiment discloses an integrated device for collecting, clearing and warning of silt in municipal pipelines, comprising a collecting pipe 1, a first filter plate 2, a second filter plate 3, a guide box 4, a fixing rod 5, an adjusting assembly 6, a hanger 7 and an early warning assembly 8. Screw holes 101 are provided on the surfaces of both ends of the collecting pipe 1. The collecting pipe 1 has a U-shaped cross section, through which sewage can pass. Drainage plates 102 are hingedly connected on both sides of the left end of the collecting pipe 1. The drainage plates 102 can introduce water flow into the collecting pipe 1, thereby facilitating subsequent silt collection. At the same time, the drainage plates 102 can be rotated, thereby adjusting the opening of the two drainage plates 102 to adapt to pipes of different widths; the first filter plate 2 is fixedly connected to the inside of the collecting pipe 1, the first filter plate 2 is tilted, the second filter plate 3 is fixedly connected to the inside of the collecting pipe 1, and is located on the left side of the first filter plate 2. The second filter plate 3 is an L-shaped plate. The two filter plates 3 are used to filter sewage and block sludge. The two guide boxes 4 are respectively fixedly connected to the front and rear end surfaces of the collecting pipe 1. The two fixing rods 5 are respectively hinged to the surfaces of the two drainage plates 102 away from each other and can rotate. A cavity 501 is opened inside the fixing rod 5 close to the end of the collecting pipe 1. The two adjustment components 6 are respectively located inside the two cavities 501. The adjustment components 6 are used to change the angle of the drainage plate 102 by adjusting the position of the fixing rods 5. The bottom of the hanger 7 is fixedly connected to the collecting pipe 1 by screws and screw holes 101 for easy disassembly. The upper end of the hanger 7 is hinged with a hanging rod 701, and the hanging rod 701 can rotate. The upper end of the hanging rod 701 is fixedly connected with a hanging rope 702. The collecting pipe 1 can be lifted by pulling the hanging rope 702, which is convenient for taking out the collecting pipe 1 and recovering the sludge. The early warning component 8 is arranged inside the collecting pipe 1.

[0021] Furthermore, a plurality of evenly distributed first filter holes 201 and second filter holes 301 are respectively provided on the upper half surfaces of the first filter plate 2 and the second filter plate 3. The first filter plate 2 and the second filter plate 3 can filter out sludge in sewage. A first sludge collecting chamber 103 is formed between the bottom of the first filter plate 2 and the bottom end of the collecting pipe 1, and a second sludge collecting chamber 104 is formed between the first filter plate 2 and the second filter plate 3. The sludge filtered out by the first filter plate 2 and the second filter plate 3 will settle in the first sludge collecting chamber 103 and the second sludge collecting chamber 104, thereby realizing the collection of sludge.

[0022] Furthermore, a slide groove 401 is formed on the surface of one end of the guide box 4 away from the collecting tube 1, one end of the fixed rod 5 is slidably connected to the inside of the slide groove 401, a through groove 402 connecting the slide groove 401 is formed at the bottom end of the guide box 4, and a plurality of equally spaced sockets 403 are formed at the upper end of the guide box 4, the sockets 403 are connected to the slide groove 401, and the guide box 4 can limit the movement of the fixed rod 5.

[0023] Furthermore, the adjustment component 6 includes a latch 601, a stop ring 603, and a spring 604. The latch 601 passes through the cavity 501 and is slidably connected to the fixing rod 5. The latch 601 can move in the vertical direction. The upper and lower ends of the latch 601 pass through the insertion hole 403 and the through slot 402 respectively. The diameter of the latch 601 is slightly smaller than the diameter of the insertion hole 403 and the width of the through slot 402. The latch 601 can slide inside the through slot 402, thereby preventing the fixing rod 5 from detaching from the guide box 4. When the latch 601 enters the insertion hole 403, the fixing rod 5 can slide in the through slot 402. 03, the fixing rod 5 can be fixed in the current position, and the bottom end of the latch 601 is fixedly connected with a pull ring 602, which can facilitate pulling the latch 601; the limiting ring 603 is movably connected to the inside of the cavity 501 and fixedly connected to the surface of the latch 601, and the limiting ring 603 can limit the movement space of the latch 601 to prevent it from escaping from the cavity 501; the spring 604 is a compression spring, the spring 604 is located at the bottom end of the limiting ring 603 and is sleeved on the latch 601, and the spring 604 applies an upward force to the latch 601.

[0024] In the above-mentioned components, by pulling the pull ring 602 downward to disengage the latch 601 from the socket 403, the fixing rod 5 can be moved left and right, thereby adjusting the opening and closing degree of the two guide plates 102 to adapt to pipes of different widths. Subsequently, the pull ring 602 is released, and the spring 604 will use its elastic force to push the latch 601 upward to make it enter the corresponding socket 403, thereby automatically fixing the guide plate 102.

[0025] Furthermore, the early warning component 8 includes a first flow sensor 801 and a second flow sensor 802, which are used to collect water flow data. The first flow sensor 801 and the second flow sensor 802 are respectively fixedly connected to the front and rear ends inside the collecting pipe 1, and can respectively detect the water flow at the water inlet and outlet ends of the collecting pipe 1 to determine whether it is blocked; the microcontroller 803 is used to collect the monitoring data of the first flow sensor 801 and the second flow sensor 802, and transmit the data to the server end. The microcontroller 803 is fixedly connected to the upper end of the second filter plate 3.

[0026] Through the above technical solution, the microcontroller 803 can collect the monitoring data of the first flow sensor 801 and the second flow sensor 802, calculate the flow difference, and determine whether there is a blockage based on the flow difference. If blockage occurs, the microcontroller 803 can send an alarm message to the server to remind the staff to come and dredge.

[0027] In order to facilitate the installation of the device on a water grate or a manhole cover, the invention also designs a connecting component, which is located at the upper end of the suspension rope 702.

[0028] In order to prevent the sludge from leaking during the process of taking out the device, the present invention arranges the hanger at one end of the collecting pipe 1 close to the water inlet.

[0029] Through the above technical solution, when the collection pipe 1 is pulled out of the pipeline by pulling the lifting rope 702, the collection pipe 1 will rotate clockwise around the lifting rod due to the unbalanced weight on the left and right sides, and because of the obstruction of the first filter plate 2 and the second filter plate 3, all the silt will not fall, thereby preventing the silt from being flushed into the pipeline and causing dredging failure.

[0030] The beneficial effect of this embodiment is that the municipal pipeline silt collection and desilting early warning integrated device described in this embodiment can filter the water in the pipeline through the first filter plate 2 and the second filter plate 3 to collect the silt, and at the same time the adjustment component 6 can adjust the angle of the two drainage plates 102 to be suitable for pipelines of different widths, and can judge whether it is blocked through the monitoring data of the two water flow sensors. Finally, the microcontroller sends an early warning message to the server side to remind the staff to desilt in time, thereby realizing the integration of silt collection and desilting early warning and realizing effective desilting of the pipeline.

[0031] Second embodiment: In conjunction with the instruction manual Figure 7-8 During the installation of the device, in order to facilitate workers to take out the device, it is necessary to connect the suspension rope 702 to the water grate. Since the shape of the water grate is a quadrilateral, the four corners are generally right angles, and a drainage groove is opened in the middle. Therefore, it is necessary to design a connecting component according to the water grate. The present invention designs a connecting piece 901, which is fixedly connected to the upper end of the suspension rope 702. The connecting piece 901 is a frame with a U-shaped cross-section, and there is an opening at the left end thereof, which can be stuck on the water grate. The left end of the connecting piece 901 is internally threaded with two symmetrical fixing bolts 9011.

[0032] Through the above technical solution, the connecting piece 901 is stuck on the surface of the water grate, and the fixing bolt 9011 is installed at a preset position, so that the hanging rope 702 can be connected to the water grate. At this time, the water grate is opened and the hanging rope 702 can be grabbed to pull the device out of the pipeline.

[0033] Third embodiment: In conjunction with the instruction manual Figure 9-10 During the installation of the device, in order to facilitate workers to take out the device, there is a situation where the hanging rope 702 needs to be connected to the manhole cover. However, the manhole cover structure is different from the water grate and lacks a connection position. Therefore, the present invention designs a magnet disk 902. When the magnet disk 902 is fixedly connected to the upper end of the hanging rope 702, the magnet disk 902 has magnetic force and can be adsorbed on the manhole cover.

[0034] Through the above technical solution, when the device needs to be connected to the manhole cover, the hanger 7 with the attached magnetic disk 902 is selected, and the magnetic disk 902 is adsorbed on the bottom surface of the manhole cover. After opening the manhole cover, the hanging rope 702 can be grasped to pull the device out of the pipeline.

[0035] In addition, the present invention also provides an early warning method, which is used for the above-mentioned municipal pipeline silt collection and desilting early warning integrated device, and specifically includes the following steps: Step 1: Collect monitoring data from two water flow sensors; Step 2: Calculate the difference between the two monitoring data and compare it with the threshold; Step 3: If the current difference is greater than the threshold, a warning message is sent to the server.

[0036] When there is a blockage inside the collecting tube 1, the flow of the fluid will be hindered. The blockage will reduce the effective cross-sectional area of ​​the collecting tube 1. According to the fluid continuity equation (in It's traffic. is the cross-sectional area of ​​the pipe, is the fluid flow rate), when the flow rate remains unchanged, a reduction in cross-sectional area will result in a decrease in flow rate.

[0037] Assume that the flow rates detected by the first flow sensor 801 and the second flow sensor 802 are and , flow difference , the difference threshold is ,when > When the collecting tube 1 is blocked, it can be determined that the collecting tube 1 is blocked.

[0038] For example, the difference threshold For example, the flow rate detected by the first flow sensor 801 is 0.1 cubic meter per second. =0.4 cubic meters per second, the flow rate detected by the second flow sensor 802 is =0.2 cubic meters per second, the difference between the two is |0.4-0.2|=0.2 cubic meters per second, > , it can be preliminarily determined that there is a blockage inside the collection pipe 1. At this time, the microcontroller 803 will send an early warning message to the server to remind the staff to come and clear the silt.

[0039] In addition, the severity of the blockage can be judged by combining the flow rate reduction ratio. ×100%, if > the first threshold, it indicates that the congestion is serious. If the second threshold ≤ ≤ the first threshold, it is moderately blocked. < the second threshold, it is a slight blockage. For example, when the first threshold is 50% and the second threshold is 20%, =35%, then 20%< <50%, so it is moderate blockage.

[0040] Through the above technical solution, the staff can judge the priority of pipeline dredging and determine the dredging order according to the severity of the blockage.

[0041] Therefore, in summary, the municipal pipeline silt collection and desilting early warning integrated device and an early warning method described in the present invention can effectively collect silt in the pipeline and issue early warning information when it is blocked.

[0042] It should be noted here that the electrical components appearing in this article are all connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0043] In short, the above is only a preferred embodiment of the technical solution of the present invention, and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
