Description

Technical Field

[0001] The present application belongs to the field of urban water technology, and in particular, relates to a drainage network anti-pollution monitoring device. Background Art

[0002] Urban drainage pipe networks are an important part of urban infrastructure. They are mainly used to collect, transport and treat sewage and rainwater in cities to ensure urban environmental sanitation and the quality of life of residents. For example, urban drainage pipe networks can quickly and effectively discharge sewage and rainwater out of urban areas through underground pipe systems. Especially in rainy seasons, drainage pipe networks can quickly divert rainwater and reduce the risk of urban waterlogging. In addition, urban drainage pipe networks can also treat urban sewage to meet standards through sewage treatment systems before discharging it, reducing pollution to the natural environment. However, since urban drainage pipe networks are deeply buried underground and the on-site working conditions are complex, various pipe network defects are prone to occur, such as pipe network damage, mixed and wrong connections of rainwater and sewage pipe networks, etc., which seriously affect the normal and healthy operation of the drainage pipe network.

[0003] For this reason, operation and maintenance managers often use drainage network anti-pollution monitoring devices to monitor the water status in the drainage network, such as temperature, to monitor the operation of the drainage network. However, due to the large amount of impurities and waste in the urban drainage network, it is easy to be attached to the monitoring device in the drainage network, affecting the normal operation of the device, thereby having a negative impact on the acquisition of monitoring data on the water status. Therefore, how to prevent pollutants from being attached to the drainage network anti-pollution monitoring device has become a technical problem that needs to be solved urgently.

[0031] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0033] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0034] At present, the operation and maintenance managers of urban drainage networks often use drainage network anti-pollution monitoring devices to monitor the changes in the water state in the drainage network to analyze the defects of the drainage network. However, due to the large amount of impurities or waste in the urban drainage network, it is easy to be attached to the monitoring device of the drainage network, affecting the normal operation of the device. Therefore, how to prevent pollutants from being attached to the drainage network anti-pollution monitoring device is a technical problem.

[0035] In order to at least solve the above-mentioned problems, an anti-pollution monitoring device for a drainage network is provided in an embodiment of the present application, which can effectively prevent the hanging of pollutants and ensure the normal operation of the device.

[0036] See also Figures 1 to 4 As shown, a drainage network anti-pollution monitoring device provided by an embodiment of the present application includes a water body monitoring module 1; the water body monitoring module 1 includes a diverter 11, a connecting bracket 12 and a water body monitoring unit 13; the rear end of the diverter 11 is in an inverted triangle shape and is connected to the water body monitoring unit 13, and the front end is a square cross-section and is connected to the connecting bracket 12; the diverter 11 floats in the inspection well 2 to monitor the water state in the drainage pipe connected to the two ends of the inspection well 2 through the water body detection unit 13.

[0037] Among them, see Figures 2 to 4 As shown, the guide body 11 is in the shape of a cone, and has no corners in the direction of the flow; the upper flat part of the guide body 11 is a float, and the lower part is metal, and the overall density of the guide body is lower than the density of the water body. The upper part of the guide body 11 is a float, and the lower part is metal, which can lower the center of gravity and guide the water flow. And because the guide body 11 is conical, it can effectively prevent garbage from hanging.

[0038] In addition, the floating material of the flow guide 11 is corrosion-resistant.

[0039] In some implementations, the floating material includes polyethylene (PE), polypropylene (PP), polyurethane foam (PU), etc., and this application does not impose any restrictions on this. In practical applications, the floating material of corresponding density can be selected according to the buoyancy requirements.

[0040] Furthermore, a lifting body wing surface 111 is used above the diversion body 11. When the water flow velocity is greater than a certain speed, the diversion body 11 is in a highly suspended state. When the flow velocity is relatively low, the diversion body 11 is easy to run aground. At this time, it can touch the bottom to reduce swinging, thereby ensuring that the entire device is in the water body and continuously monitoring water body information.

[0041] Among them, see Figures 2 to 4As shown, the connecting bracket 12 is an L-shaped hardened bracket. The connecting bracket 12 can ensure the durability of the wire under twisting, and due to the L-shaped design, it can give the water monitoring module 13 a downward force by means of the weight of the cable in the case of low water level, thereby ensuring that the water monitoring module 13 can contact the water in the inspection well 2.

[0042] Among them, see Figures 2 to 4 As shown, the shape of the water body monitoring unit 13 is also an inverted triangle shape, which is the same as the front end of the guide body 11. A temperature probe 134 is provided below the water body detection unit 13, and the temperature probe 134 collects water temperature information in the drainage pipe. And the temperature probe 134 is arranged below the water body monitoring unit 13, which can effectively lower the center of gravity of the equipment.

[0043] For further information, see Figures 2 to 4 As shown, a group of plate-type vortex generators 131 are symmetrically provided on both sides of the middle of the temperature probe 134, so as to enhance the fluid acceleration around the temperature probe 134 and strengthen the heat exchange, so that the temperature probe 134 can monitor information more accurately.

[0044] For further information, see Figures 2 to 4 As shown, a compression flow enhancement cavity 132 is provided behind the temperature probe 134. Due to the presence of air in the compression flow enhancement cavity, under the condition of pulsating flow velocity, affected by the turbulence of the wake vortex pressure, the gas volume is continuously compressed and changed to form resonance, thereby enhancing the mixing effect of the tail fluid, enhancing the pulsating flow of the fluid around the temperature probe 134, enhancing heat exchange, reducing the thickness of the laminar boundary layer of the temperature probe 134, and reducing the thermal inertia of the temperature probe 134, so that the temperature probe 134 can monitor information more accurately.

[0045] Furthermore, an ultrasonic cavitation generator is provided in the compression flow enhancement cavity 132. Ultrasonic cavitation means that when the ultrasonic energy is high enough, tiny bubbles (cavitation nuclei) in the liquid vibrate, grow and continuously gather the sound field energy under the action of the ultrasonic field, thereby further enhancing the turbulence of the water body around the temperature probe 134, further enhancing the heat exchange effect, reducing the thermal inertia of the temperature probe 134, and enabling the temperature probe 134 to monitor information more accurately.

[0046] For further information, see Figures 2 to 4As shown, the lower end of the water body monitoring unit 13 is provided with a folded guide rudder 133. The unfolded design follows the water flow to ensure that the device will not get caught by garbage. When the fluid flows through the irregular guide rudder 133, deflection will occur. The guide rudder 133 will generate lateral thrust when facing the flow. The water body monitoring unit 13 as a whole will tilt laterally with the connecting bracket 12 as the axis, and then due to the effect of the center of gravity, the tilt will be restored and continue to vibrate at a low frequency, thereby strengthening the entire turbulent effect and strengthening the shaking of the water body monitoring unit 13, so that the fluid around the temperature probe 134 can be accelerated, heat exchange can be strengthened, and the temperature probe 134 can monitor information more accurately.

[0047] In some embodiments, see Figures 2 to 4 As shown, the water body monitoring module 1 is a streamlined structure, which gradually narrows from top to bottom. While reducing the flow area and ensuring stable flow, the streamlined shape can avoid garbage hanging on the device to the greatest extent to ensure the normal operation of the device.

[0048] Furthermore, the vertical section of the L-shaped hardened bracket is connected to a cable, and the cable is used to transmit the monitoring information collected by the water body monitoring module to the processing module. The processing module determines whether the drainage pipe is damaged or leaking according to the received monitoring information.

[0049] Furthermore, the processing module includes an alarm unit, and the alarm unit includes a text message alarm and / or a warning light.

[0050] When the urban drainage network operates normally, the type of water in the drainage pipe is fixed. Due to the difference in temperature between different types of water, when defects in the pipeline cause multiple types of water to mix, the water temperature will change significantly due to temperature neutralization. Therefore, after the water monitoring module 1 obtains the monitoring information of the water status in the drainage pipe, the cable transmits the monitoring information to the processing module. At this time, the processing module will determine whether the drainage pipe is damaged or leaking based on the monitoring information, so that the operation and maintenance personnel can repair the drainage pipe in time.

[0051] In some embodiments, the temperature probe 134 in the water monitoring unit 13 collects temperature information of the water body. If the drain pipe is damaged or leaking, the water in the drain pipe will be mixed. At this time, the water temperature will change significantly due to temperature neutralization. When the processing module analyzes whether the water temperature change exceeds the preset threshold based on the monitoring information. If it exceeds the preset threshold, it means that the drain pipe is damaged or leaking.

[0052] The water monitoring module 1 in the drainage network anti-pollution monitoring device provided in the above-mentioned embodiment of the present application can float in the inspection well 2, and then monitor the water state in the drainage pipe connected to both ends of the inspection well 2 in real time.

[0053] In some embodiments, the drainage network anti-pollution monitoring device provided by the present application is placed in the inspection well, and the temperature probe 134 integrated under the water body monitoring module 1 will collect the temperature information of the water body accordingly. When the drain pipe is not damaged or leaking, the water body in the drain pipe is stable, and the temperature information of the water body will show periodic regular fluctuations, which is related to the residents' water use patterns in the morning and evening. Once the drain pipe has groundwater leakage, rainwater mixing, and wastewater secret discharge, the water body in the drain pipe will be mixed. At this time, the temperature of the water body will change significantly compared to the sunny day without mixing. At this time, the processing module receives the monitoring information and analyzes whether the temperature information change of the water body exceeds the set threshold. If it exceeds the preset threshold, it means that the drain pipe is damaged or leaking. At this time, the alarm unit in the processing module will issue an alarm so that the operation and maintenance personnel can maintain the drain pipe in time.

[0054] As described above, the drainage network anti-pollution monitoring device provided in the present application adopts a special streamlined structure design to enable the water body monitoring module in the drainage pipe to float in the inspection well, thereby avoiding a large amount of garbage hanging on it and ensuring that the drainage network anti-pollution monitoring device can operate normally.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
