Description

Technical Field

[0001] The present application belongs to the technical field of municipal pipe networks and relates to a temperature monitoring device for a drainage pipe network. Background Art

[0002] Drainage networks are crucial for transporting sewage and discharging rainwater. They maintain urban sanitation and public health, effectively preventing urban waterlogging, protecting urban water quality, improving overall urban environmental quality, and promoting sustainable urban development. Therefore, the proper functioning of urban drainage networks plays a vital role in the healthy development of cities. However, due to their deep underground location and complex on-site conditions, the development of urban drainage networks is prone to various network defects, such as pipe damage and misconnected stormwater and sewage pipes. These defects severely impact the proper and healthy operation of drainage networks and increase the risks of urban waterlogging and combined sewer overflow pollution.

[0003] Operation and maintenance managers monitor the operation of the drainage network by monitoring the water status in the drainage network, such as temperature. However, due to the relatively complex internal environment of the urban drainage network, the water volume, water level, flow rate, etc. will change significantly at different times or under different rainfall conditions. When the water volume is large, it is easy to cause an impact on the equipment terminal. At the same time, there may be uneven vertical mixing in large-diameter sewage pipes, and the water temperature may be stratified. Therefore, how to monitor the water status in the drainage network when there are significant changes in water volume, water level, flow rate, etc. has become a technical problem that needs to be solved urgently.

[0050] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed 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 unless they conflict.

[0051] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation.

[0052] Drainage networks are crucial for transporting sewage and discharging rainwater. They maintain urban sanitation and public health, effectively preventing urban waterlogging, protecting urban water quality, improving overall urban environmental quality, and promoting sustainable urban development. Therefore, the proper functioning of urban drainage networks plays a vital role in the healthy development of cities. However, due to their deep underground location and complex on-site conditions, the development of urban drainage networks is prone to various network defects, such as pipe damage and misconnected stormwater and sewage pipes. These defects severely impact the proper and healthy operation of drainage networks and increase the risks of urban waterlogging and combined sewer overflow pollution.

[0053] Different types of water have different temperatures. If a pipeline defect causes multiple water types to mix, the temperature of the mixed water will change significantly due to temperature neutralization, as the temperature differences between the different incoming waters are significant. Therefore, water temperature changes can effectively assist operations and maintenance personnel in analyzing network defects. Due to the relatively complex internal environment of urban drainage networks, water volume, water level, and flow rate can vary significantly over time or under different rainfall conditions. High water volumes can easily impact equipment terminals, leading to risks such as equipment failure.

[0054] In order to at least solve the above problems, an embodiment of the present application provides a drainage network temperature monitoring device that can accurately monitor the temperature of the drainage liquid flowing through the drainage pipe in the inspection well when there are significant changes in water volume, water level, flow rate, etc.

[0055] The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application.

[0056] like Figure 1 As shown, this embodiment provides a drainage network temperature monitoring device, which includes: a mounting module 1, a temperature monitoring module 2, and a stabilization module 3. The temperature monitoring module 2 and the stabilization module 3 float in an inspection well 6 to detect changes in water temperature in the drainage pipe 5 connected at both ends of the inspection well. The stabilization module 3 is arranged above the temperature monitoring module 2 to stabilize the temperature monitoring module 2 in the middle of the drainage pipe 5. The mounting module 1 is fixed to both sides of the inspection well and is connected to the temperature monitoring module 2 and the stabilization module 3 via a cable 4.

[0057] According to the above description, the drainage network temperature monitoring device provided by the present application can use the temperature monitoring module located in the center of the drainage pipe to monitor the temperature changes of the water in the drainage pipes connected at both ends of the inspection well. It is not affected by the water flow and the data monitoring accuracy is high. In addition, by using the mounting modules fixed on both sides of the inspection well and the stabilization module arranged above the temperature monitoring module, it can be ensured that the temperature monitoring module can be stably placed in the water body in the inspection well to avoid up and down floating, offset and damage caused by the impact of the water flow, providing stable and reliable temperature change monitoring. Real-time transmission through the cable facilitates the operation and maintenance management personnel to monitor and analyze the water status in the drainage pipe.

[0058] Figure 2 Shown is a schematic diagram of the structure of a stabilization module in one embodiment of the present application. Figure 2 As shown, the stabilization module 3 includes multiple depth-regulating floats 31 and a stabilizing rudder 32. The stabilizing rudder 32 is arranged above the temperature monitoring module 2. The multiple depth-regulating floats 31 are respectively arranged at both ends of the stabilizing rudder 32. The multiple depth-regulating floats 31 are connected to the stabilizing rudder 32 via the cable 4. The stabilizing rudder 32 is made of metal.

[0059] Exemplarily, the number of the depth-setting floats is an even number.

[0060] In one embodiment of the present application, the temperature monitoring module 2 includes a temperature monitoring sensor; the temperature monitoring sensor is fixed below the stabilizing rudder 32; and both ends of the temperature monitoring sensor 32 are respectively connected to the plurality of constant depth floats 31.

[0061] For example, the stabilizing rudder 32 is made of metal and has a certain weight. It can provide downward pressure to the temperature monitoring sensor, provide a certain stability to the temperature monitoring sensor, and drive the temperature monitoring sensor to sink to the center of the drain pipe. When the depth-fixing float 31 is immersed in the liquid, it will rise to a certain height due to the buoyancy. By adjusting the size and position of the depth-fixing float, the size of the buoyancy can be controlled, and then the depth of the temperature monitoring sensor in the drain pipe can be controlled to avoid temperature measurement deviations due to depth changes. The depth-fixing float 31 and the stabilizing rudder 32 are connected together by a bidirectional cable to form a stable balance system. Through their joint action, they can ensure that the temperature monitoring sensor always remains in the middle of the drain pipe. When water flows, the depth-fixing float 31 will move up and down with the flow of water, thereby driving the temperature monitoring sensor to move accordingly. Because the depth-regulating float 31 is connected to the stabilizing rudder 32 via a cable 4, the buoyancy of the depth-regulating float 31 and the gravity of the stabilizing rudder 32 cause the depth-regulating float 31 to move while the gravity of the stabilizing rudder 32 sinks. This maintains the temperature monitoring sensor in a fixed position, preventing the sensor from being affected by water flow and enabling accurate water temperature measurement. The design of the stabilizing rudder and depth-regulating float effectively protects the temperature monitoring sensor from water flow, extending its service life and ensuring stable operation of the device.

[0062] In one embodiment of the present application, the size and position of the plurality of depth-regulating floats 31 are adjustable. The depth-regulating floats can be adjusted in position and sized appropriately according to the flow and depth of different drainage pipe networks, thus having strong adaptability and a wide range of applications.

[0063] Specifically, a stabilizing paddle of appropriate weight is selected based on the flow rate within the drainage network. Depth-regulating floats are placed on either side of the paddle to balance the forces acting on it. The size of the depth-regulating float is matched to the weight of the paddle. The float exerts varying buoyancy at different locations on the cable, influenced by the flow and depth within the drainage pipe. By adjusting the size and position of the depth-regulating float to the appropriate level based on the weight of the paddle, the temperature monitoring sensor on the cable remains in the center of the drainage pipe, preventing excessive force and displacement.

[0064] For example, when the water level rises, the depth-regulating float provides excess buoyancy, causing the stabilizing rudder, temperature sensor, depth-regulating float, and traction cable to move upward under the elastic structure of the take-up reel until the depth-regulating float returns to its original submerged depth. Conversely, when the water level drops, the float moves downward until the depth-regulating float returns to its original submerged depth, thus achieving fixed-depth placement of the temperature probe.

[0065] Figure 3 The diagram shows the structural diagram of the stabilizing rudder setting direction in one embodiment of the present application. Figure 3As shown, the setting direction of the stabilizing fin 32 is parallel to the flow direction of the drainage liquid in the drainage pipe 5.

[0066] For example, the first and second depth-regulating floats 311 and 312 are fixed to the first and second ends 321 and 322 of the stabilizing rudder, respectively. The stabilizing rudder 32 is positioned so that its fan-shaped apex faces the manhole rim 61, and its fan-shaped edge faces the manhole bottom 62. The first end 321 of the stabilizing rudder corresponds to the first drain pipe 51, and the second end 322 corresponds to the second drain pipe 52. The orientation of the stabilizing rudder 32 is parallel to the flow direction of the drainage liquid in the drainage pipe 5. Drainage liquid in the drainage network can flow through the first drain pipe 51, the first depth-regulating float 311, the first end 321 of the stabilizing rudder, through the second end 322 of the stabilizing rudder, and the second depth-regulating float 312, and then out through the second drain pipe 52. Alternatively, the liquid can flow through the second drain pipe 52, the second depth-regulating float 312, the second end 322 of the stabilizing rudder, through the first end 321 of the stabilizing rudder, and the first depth-regulating float 311, and out through the first drain pipe 51.

[0067] For example, the stabilizing rudder has a fan-shaped structure, and the temperature monitoring sensor is fixed below the fan-shaped edge of the stabilizing rudder. The fan-shaped design of the stabilizing rudder effectively reduces the possibility of garbage entanglement, primarily due to the following: 1) The fan-shaped structure has a relatively smooth surface, without sharp edges or protrusions, which reduces the number of points where garbage can adhere and become entangled. 2) When the fan-shaped stabilizing rudder moves through the water, the water flows along its surface, acting as a wash, removing any garbage adhering to the rudder surface and preventing entanglement. Furthermore, the water flow makes it easier for garbage to bypass the fan-shaped structure, rather than directly impacting and becoming entangled. 3) When impacted by the water flow, the fan-shaped stabilizing rudder has a larger force-bearing area, dispersing the impact force and reducing the intensity of the impact on the rudder. This dispersal of the impact force also weakens the impact force on the garbage, reducing the possibility of garbage entanglement. 4) The fan-shaped stabilizing rudder can guide garbage around, preventing it from directly impacting and becoming entangled with the rudder. During its flow, garbage is more likely to bypass the fan-shaped structure, rather than directly impacting and becoming entangled. Furthermore, the fan-shaped structure of the stabilizer ensures uniform center of gravity distribution, effectively resisting water flow shock and preventing the device from tilting or flipping. This reduces the impact of lateral water flow on the temperature monitoring device below the stabilizer, further ensuring the stability of the device. The fan-shaped structure of the stabilizer can adapt to drainage pipes of varying diameters, facilitating installation and commissioning. Furthermore, the size and position of the depth-regulating float can be adjusted according to the flow rate and water depth within the drainage pipe network to ensure that the temperature monitoring sensor remains centrally located within the pipe network.

[0068] Figure 4 Shown is a schematic diagram of the structure of the mounting module in one embodiment of the present application. Figure 4As shown, the mounting module 1 includes a take-up reel 11, a mounting bracket 12, a cable trough 13, and a hanging body 14. The take-up reel 11 and the hanging body 14 are respectively fixed to the two sides of the inspection well 6. The cable trough 13 is fixed to the well ring 61 of the inspection well and is connected to the take-up reel 11 via the cable 4. The take-up reel 11 is connected to the hanging body 14 via the cable 4. The mounting module 1 also includes an auxiliary battery 15, which is connected to the take-up reel 11.

[0069] Specifically, one end of the cable is fixed, and the length of the fixed end of the take-up reel is adjustable. The take-up reel and the cable are hoisted into the inspection well via the mounting bracket and the cable trough, and are slightly higher than the drainage pipe. The length of one end of the cable is slightly longer than the hanging body and reaches the height of the bottom of the inspection well. The other end of the cable is slightly lower than the height of one end of the take-up reel. Under the action of the take-up reel, the height of the temperature probe between the bottom of the inspection well and the take-up reel can be automatically adjusted according to the water level.

[0070] For example, the take-up reel has an elastic structure. When the depth-regulating float is submerged in the drainage fluid, the buoyancy of the float allows the reel to hook and re-hook the cable. When the depth-regulating float is submerged in the drainage fluid, the buoyancy causes the float to float upward, driving the cable upward. At this point, the reel's elastic structure acts as a buffer, preventing the cable from breaking or being damaged due to the float's rapid rise. When the reel's elastic structure is subjected to cable tension, it deforms, firmly securing the cable to the reel. As the float rises and drives the cable upward, the reel's elastic structure stretches. Once the float reaches a certain height, the reel's elastic structure returns to its original shape, firmly hooking the cable and preventing it from falling off. The reel's elastic structure effectively protects the cable from damage, extending its service life. Furthermore, the elastic structure prevents the cable from breaking due to excessive stretching, ensuring stable operation of the device and accurate temperature monitoring.

[0071] Exemplarily, the hanging body is a cable hanging body, and the hanging body can be a sensing device, such as a humidity sensor, a pressure sensor, etc. Figure 5 Shown is a schematic diagram of the structure of the top fixing ring in one embodiment of the present application. Figure 5 As shown, the mounting module also includes a top fixing ring 16, which is composed of an outer horizontal ring layer 161 and an inner barreled vertical ring layer 162. The top fixing ring 16 is a thin steel structure. The diameter of the outer horizontal ring layer 161 matches the diameter of a conventional manhole cover, and the inner barreled vertical ring layer 162 matches the diameter of the manhole seat. The entire device can be placed and embedded in an existing manhole. When the manhole cover is closed, the fixing ring is sandwiched between the cover and the seat, providing a certain degree of stability.

[0072] In one embodiment of the present application, the cable 4 passes through the take-up wheel 11 and sequentially passes through the first end 321 of the stabilizing rudder, the first constant depth float 311, the temperature monitoring sensor and the second constant depth float 312 of the second end 322 of the stabilizing rudder and is inserted into the hanging body 14; the temperature monitoring sensor is arranged in the middle of the cable 4, and the take-up wheel 11 and the hanging body 14 hoist the temperature monitoring sensor in the middle position of the drain pipe 5.

[0073] Specifically, the cable in the cable trough is bidirectional and is inserted into the hanger via a take-up reel. The center of the bidirectional cable is immersed in the drainage fluid, allowing it to float with the water in the drainpipe, reducing the impact of high liquid levels and large water volumes on the temperature monitoring sensor. This submersion reduces the cable's weight, increases its flexibility, and makes it more adaptable to fluctuating water flows within the drainpipe. The take-up reel and hanger are fixed to the manhole, while the depth-regulating float, stabilizing rudder, and temperature monitoring sensor are hoisted into the center of the cable. The buoyancy of the cable and the weight of the stabilizing rudder maintain the temperature monitoring sensor's position in the center of the drainpipe through the buoyancy of the cable and the gravity of the stabilizing rudder. When the drainpipe is high and the water velocity is high, the gravity-driven sinking action of the stabilizing rudder counteracts the impact of the water flow, stabilizing the temperature monitoring sensor. The buoyancy of the depth-regulating float maintains the temperature monitoring sensor at a specific depth in the drainage fluid, accurately monitoring water temperature changes. This prevents temperature measurement deviations and reduces the impact of high liquid levels and large water volumes on the temperature monitoring sensor.

[0074] For example, when the amount of water in the drainage network changes, for example, when the rainfall increases, the amount of water in the drainage network will increase sharply, and at this time the temperature monitoring device can monitor the drop in water temperature. If the monitored temperature drop is proportional to the rainfall, it means that the drainage network is operating normally; if the temperature drop is not proportional to the rainfall, there may be a network defect, such as a broken pipe causing groundwater to seep in. When the water level in the drainage network changes, for example, when the water level in the drainage network rises, the temperature monitoring device can monitor the change in water temperature. If the monitored temperature change is proportional to the increase in the water level, it means that the drainage network is operating normally; if the temperature change is not proportional to the increase in the water level, there may be a network defect, such as siltation in the pipe causing poor water flow. When the flow rate in the drainage network changes, for example, when the flow rate in the drainage network changes, the temperature monitoring device can monitor the change in water temperature. If the monitored temperature change is proportional to the flow rate change, it means that the drainage network is operating normally; if the temperature change is not proportional to the flow rate change, there may be defects in the network, such as a bent pipe causing poor water flow.

[0075] In summary, the drainage network temperature monitoring device provided by the present application can use a temperature monitoring sensor to monitor the temperature changes of the water body in the drainage pipe connected to both ends of the inspection well. The temperature monitoring sensor is located in the center of the drainage pipe and can accurately measure the temperature changes of the water body without being affected by the water flow, and the data accuracy is high. In addition, by fixing the winding wheel and hanging body on both sides of the inspection well and the stabilizing rudder and fixed depth float arranged above the temperature monitoring sensor, it can be ensured that the temperature monitoring sensor can be stably placed in the water body in the inspection well, avoiding up and down floating, deviation and damage caused by the impact of the water flow, and providing stable and reliable temperature change monitoring for the drainage fluid. At the same time, the fixed depth float and stabilizing rudder can be adjusted according to the water flow and water depth of different drainage networks, with strong adaptability and a wide range of applications.

[0076] The drainage network temperature monitoring device provided by this application can be applied to application scenarios such as urban drainage network, industrial wastewater treatment, and water resource management. When the drainage network temperature monitoring device is applied to the urban drainage network, it can monitor the temperature changes of water bodies in the urban drainage network, promptly discover network defects, prevent urban waterlogging and combined sewer overflow pollution, and ensure the safety of the urban water environment. When the drainage network temperature monitoring device is applied to industrial wastewater treatment, it can monitor the temperature changes of water bodies during the industrial wastewater treatment process, control the treatment effect, ensure that the water quality meets the standards, and protect the ecological environment. When the drainage network temperature monitoring device is applied to water resource management, it can monitor the temperature changes of water bodies such as rivers and lakes, study the laws of water environment changes, provide data support for water resource management, and promote the rational use and protection of water resources. In addition, the drainage network temperature monitoring device provided by this application can be combined with other sensors (such as water level sensors, flow sensors, pressure sensors, etc.) to achieve multi-parameter monitoring of the drainage network, further improving the management efficiency of the drainage network.
