Description

Technical Field

[0001] This invention relates to the field of intelligent manhole cover technology, and in particular to a manhole cover capable of identifying mixed rainwater and sewage flow, and its method of use. Background Technology

[0002] To create high-quality residential communities, separate stormwater and sewage systems are being implemented to improve urban water quality and prevent water pollution. Traditional residential communities are gradually undergoing drainage system renovations, with stormwater and sewage now discharged through separate pipes into stormwater wells or sewage wells, and then into the municipal sewer network, thus achieving separate discharge of stormwater and sewage.

[0003] To facilitate maintenance personnel's inspection of storm drains and sewage wells and to test the water quality inside, manual markings are typically made in advance on different well covers. Inspectors then verify the water quality test results against the markings on the well covers to confirm that the water quality corresponds to the specific well, preventing the mixing of storm and sewage pipes and the resulting illegal discharge of sewage into storm drains. However, current monitoring relies entirely on periodic manual inspections, which cannot promptly detect illegal sewage discharge. Therefore, a solution is urgently needed.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a manhole cover that can identify mixed rainwater and sewage flow and its usage method. The manhole cover can not only monitor the water flowing into the well and prevent sewage from being illegally discharged, but also has a simple structure, low cost, and can be widely applied and promoted.

[0009] Preferably, the water detection component further includes a movable guide bar and a sliding guide groove; the movable guide bar is disposed on the top of the filter cylinder; the sliding connection between the rainwater drain pipe and the filter cylinder is provided with a guide hole for the movable guide bar to pass through, the guide hole is distributed along the length direction of the rainwater drain pipe and extends towards the outlet of the rainwater drain pipe; the sliding guide groove is disposed on the guide hole and forms a sliding connection with the movable guide bar.

[0010] Preferably, the movable guide bar is configured as a dovetail shape, and the sliding guide groove is configured as a dovetail groove.

[0011] Preferably, the water detection component further includes a cleaning channel installed on the ground surface; the cleaning channel is opposite to the installation location of the filter cartridge and is connected to the rainwater drain pipe, and a telescopic motor for removing the filter cartridge from the rainwater drain pipe is installed on the cleaning channel; the telescopic rod of the telescopic motor is connected to the sliding guide groove; the inner wall of the cleaning channel is provided with cleaning brushes for cleaning impurities on the filter screens on both sides of the filter cartridge.

[0012] Preferably, it also includes a reset channel disposed in the ground surface; the reset channel is connected to the top of the rainwater drain outlet and is used to remove the filter cartridge pushed to the rainwater drain outlet by sewage; the pressure sensor is installed in the reset channel and is opposite to the moving guide bar on the filter cartridge.

[0013] Preferably, the reset channel is provided with an openable and closable cover.

[0014] Preferably, the water detection component further includes a controller electrically connected to both the electronic display and the pressure sensor; the controller is electrically connected to the telescopic motor and controls the telescopic motor to periodically pick up and place the stationary filter cartridge for cleaning.

[0015] Preferably, the method of using the manhole cover is as follows:

[0016] S1, connect the movable guide bar on the filter cylinder to the sliding guide groove at the end of the telescopic rod of the telescopic motor, and control the telescopic motor through the controller to put the filter cylinder into the rainwater drainage pipe;

[0017] S2, the controller is used to set the time for the telescopic motor to pick up and put down the filter cylinder, and to clean the filter screens on both sides of the filter cylinder at regular intervals;

[0018] S3, when the rainwater drain pipe is connected to the sewage drain pipe, the sewage flows along the rainwater drain pipe, and the impurities in the sewage block the filter screen of the filter cylinder.

[0022] S7. After locating the point of mixing between rainwater and sewage on the rainwater drain pipe, the maintenance personnel opened the openable cover on the reset channel, cleaned the filter cartridge, reinstalled it on the telescopic motor, and then used the telescopic motor to put it back into the rainwater drain pipe along the cleaning channel.

[0023] The beneficial effects of this invention are reflected in:

[0024] (1) This invention installs a sewage monitoring component on the manhole cover and rainwater drainage pipe to monitor the water flowing through the rainwater drainage pipe, and displays the monitored sewage discharge information on the manhole cover. This setup not only monitors the water flowing into the manhole, enabling maintenance personnel to promptly detect and rectify mixed rainwater and sewage pipes, thus improving work efficiency, but also features a simple structure, low cost, and can be widely applied and promoted.

[0025] (2) This invention incorporates a pressure sensor and a filter cylinder, with the filter cylinder installed inside the rainwater drain pipe. The filter screen on the filter cylinder blocks impurities in the sewage, and the outer wall of the filter cylinder is slidably connected to the inner wall of the rainwater drain pipe. The pressure sensor is electrically connected to an electronic display and is installed at the outlet of the rainwater drain pipe, opposite the filter cylinder. When the rainwater drain pipe is illegally connected to a sewage drain pipe, the sewage contains many impurities, which quickly accumulate at the filter cylinder, clogging the filter screen and causing water flow stagnation. This pressure compresses the filter cylinder, pushing it along the inside of the rainwater drain pipe towards the outlet until it compresses the pressure sensor. This allows the pressure sensor to detect sewage discharge into the rainwater drain pipe and transmit the monitoring information to the electronic display, creating an early warning. This facilitates timely detection and handling of illegal sewage discharge by maintenance personnel, improving work efficiency.

[0026] (3) The present invention is equipped with a cleaning channel and a telescopic motor, and a cleaning brush is installed on the inner wall of the cleaning channel. When the telescopic motor drives the filter cylinder to pick up and remove, it can clean the impurities on the filter screens on both sides of the filter cylinder, so as to avoid the accumulation of fine impurities in the rainwater for a long time and block the filter cylinder, causing the filter cylinder to move, thereby improving the accuracy of the manhole cover display information.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] See Figures 1 to 3 As shown:

[0039] The present invention provides a manhole cover that can identify mixed rainwater and sewage flow, comprising: a rainwater well 10 buried under the ground surface A, a manhole cover 20 covering the rainwater well 10, a rainwater drainage pipe 30 connected to the rainwater well 10, and a sewage monitoring component.

[0040] Wastewater monitoring components are installed on the manhole cover 20 and the rainwater drainage pipe 30 to monitor the water flowing through the rainwater drainage pipe 30 and display the detected wastewater discharge information on the manhole cover 20.

[0041] This setup allows operators to promptly detect illegal sewage discharge from the rainwater well 10 via information on the manhole cover 20. It also enables them to identify the illegally connected rainwater and sewage pipe 30 using the sewage monitoring components. This enhances oversight and facilitates timely identification of connected pipes by maintenance personnel, improving the efficiency of rectification.

[0042] The wastewater monitoring component consists of an electronic display 21 and a water body detection component for determining the water quality of the water flowing through the rainwater drain pipe 30.

[0043] The electronic display 21 is installed on the manhole cover 20 and is electrically connected to the water detection component. The surface of the electronic display is covered with transparent tempered glass and is waterproofed. In daily use, it can clearly show whether there is a sewage pipe mixed with the rainwater drainage pipe 30 connected to the rainwater well 10.

[0044] The water detection component is installed in the rainwater drain pipe 30 and is located at the connection between the rainwater drain pipe 30 and the rainwater well 10.

[0045] The water detection component consists of a pressure sensor 22, a filter cylinder 40, a moving guide bar 41, and a sliding guide groove 54.

[0046] The filter cartridge 40 is installed inside the rainwater drain pipe 30, and the filter screen on the filter cartridge 40 blocks impurities in the sewage. The outer wall of the filter cartridge 40 and the inner wall of the rainwater drain pipe 30 are slidably connected. When the rainwater drain pipe 30 is illegally connected to the sewage drain pipe, due to the large amount of impurities in the sewage, it will quickly accumulate at the filter cartridge 40, clogging the filter screen, causing water flow to stagnate, and squeezing the filter cartridge 40, pushing it along the inside of the rainwater drain pipe 30 towards the outlet of the rainwater drain pipe 30.

[0047] A movable guide bar 41 is disposed on the top of the filter cylinder 40. A guide hole for the movable guide bar 41 to pass through is provided at the sliding connection between the rainwater drain pipe 30 and the filter cylinder 40. The guide holes are distributed along the length of the rainwater drain pipe 30 and extend towards the outlet of the rainwater drain pipe 30. A sliding guide groove 54 is disposed on the guide hole and forms a sliding connection with the movable guide bar 41.

[0048] With this arrangement, the moving guide bar 41 and the sliding guide groove 54 are nested together. By adjusting the friction between the moving guide bar 41 and the sliding guide groove 54, the outer wall of the filter cylinder 40 can fully contact the inner wall of the rainwater drain pipe 30 to form a sliding connection, while also forming a certain damping to prevent the filter cylinder 40 from moving along the rainwater drain pipe 30 under the push of rainwater.

[0049] Pressure sensor 22 is electrically connected to electronic display 21 and is installed at the outlet of rainwater drain pipe 30, opposite to filter cylinder 40. When filter cylinder 40 moves to the outlet of rainwater drain pipe 30, it will compress pressure sensor 22, which will then be detected by pressure sensor 22.

[0050] The water detection component also includes a cleaning channel installed within surface A; the cleaning channel is opposite to the installation location of the filter cartridge 40 and connects to the rainwater drain pipe 30, with the connection point between the cleaning channel and the rainwater drain pipe 30 allowing the filter cartridge 40 to pass through. A mounting bracket 52 is installed on the cleaning channel, and a telescopic motor 51 is mounted on the mounting bracket 52 to remove the filter cartridge 40 from the rainwater drain pipe 30. The telescopic rod 53 of the telescopic motor 51 is connected to a sliding guide groove 54; the moving guide bar 41 is dovetail-shaped, and the sliding guide groove 54 is a dovetail groove.

[0051] With this configuration, when the sliding guide groove 54 is pulled by the telescopic rod 53, the moving guide bar 41 can be lifted, thereby removing the filter cylinder 40 from the rainwater drain pipe 30.

[0052] The inner wall of the cleaning channel is provided with cleaning brushes 55 for cleaning impurities on both sides of the filter screen of the filter cylinder 40. When the filter cylinder 40 is taken out of the rainwater drain pipe 30, it comes into contact with the cleaning brushes 55, thereby removing the impurities clogging the filter screen.

[0053] In actual use, the telescopic motor 51 can be controlled at regular intervals to pick up and put down the filter cylinder 40. This allows the impurities in the rainwater in the rainwater drain pipe 30 to be collected on the filter screen of the filter cylinder 40 and cleaned at regular intervals. This prevents the rainwater drain pipe 30 from being blocked due to the accumulation of impurities in the rainwater for a long time, which would squeeze the filter cylinder 40 and cause it to move.

[0054] It also includes a reset channel 61 located in the ground surface A, and the reset channel 61 is equipped with an openable and closable cover.

[0055] The reset channel 61 communicates with the top of the outlet of the rainwater drain pipe 30 and is used to remove the filter cartridge 40 that has been pushed to the outlet of the rainwater drain pipe 30 by sewage. The pressure sensor 22 is installed in the reset channel 61 and is opposite to the moving guide bar 41 on the filter cartridge 40. A moving channel is provided between the reset channel 61 and the cleaning channel, through which the moving guide bar 41 can pass, to prevent the filter cartridge 40 from being obstructed when moving along the rainwater drain pipe 30.

[0056] When the moving guide bar 41 of the water filter cylinder 40 squeezes the pressure sensor 22, it will be detected by the pressure sensor 22.

[0057] The water detection component also includes a controller that is electrically connected to both the electronic display 21 and the pressure sensor 22. The controller is electrically connected to the telescopic motor 51 and controls the telescopic motor 51 to periodically remove and place the stationary filter cartridge 40 for cleaning.

[0058] Example 2

[0059] The following are the instructions for using manhole covers:

[0060] S1, connect the movable guide bar 41 on the filter cylinder 40 to the sliding guide groove 54 at the end of the telescopic rod 53 of the telescopic motor 51, and control the telescopic motor 51 to put the filter cylinder 40 into the rainwater drain pipe 30 through the controller.

[0061] S2, the controller sets the telescopic motor 51 to time the time for picking up and putting down the filter cylinder 40, and cleans the filter screens on both sides of the filter cylinder 40 at regular intervals.

[0062] S3, when the rainwater drain pipe 30 is connected to the sewage drain pipe, the sewage flows along the rainwater drain pipe 30, and the impurities in the sewage block the filter screen of the filter cylinder 40. When the water flow thrust is greater than the damping between the filter cylinder 40 and the rainwater drain pipe 30, the filter cylinder 40 is pushed by the sewage to move along the inside of the rainwater drain pipe 30 toward the outlet of the rainwater drain pipe 30.

[0063] S4, the filter cylinder 40 moves to the outlet of the rainwater drain pipe 30, and the moving guide bar 41 on the filter cylinder 40 abuts against the pressure sensor 22.

[0064] S5, the pressure sensor 22 transmits the detection information to the controller; the controller processes the information and displays the warning information on the electronic display 21 on the manhole cover 20.

[0065] S6. Based on the information displayed on the electronic display 21, the maintenance personnel identify the rainwater drain pipe 30 that is mixed with sewage and conduct an inspection to find the point of mixing.

[0066] S7. After locating the rainwater and sewage mixing point on the rainwater drain pipe 30, the maintenance personnel opened the openable cover on the reset channel 61, cleaned the filter cylinder 40, reinstalled it on the telescopic motor 51, and then used the telescopic motor 51 to put it back into the rainwater drain pipe 30 along the cleaning channel.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
