Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection in drainage pipe networks, and in particular to a floating ball for monitoring water temperature in drainage pipe networks. Background Art

[0002] Urban drainage networks are a key component of urban infrastructure, responsible for transporting sewage and discharging rainwater, and are essential for maintaining urban environmental sanitation and public health. The effective operation of drainage networks helps prevent urban waterlogging, protect the water quality of urban water environments, and promote sustainable urban development. Because drainage networks are buried deep underground and the environment is complex, network defects such as damage or mixing of rainwater and sewage are difficult to detect in a timely manner. These defects may cause different types of water bodies to mix, such as sewage and rainwater. There are significant temperature differences between different water bodies. When they mix due to network defects, temperature neutralization occurs, resulting in significant changes in water body temperature. This temperature change provides a potential indicator for monitoring network defects.

[0003] Since the temperature probe needs to fit tightly to the water body in order to sensitively sense the temperature change of the water body, the miniaturized design of the temperature probe also makes it difficult for it to stay in the water body stably in the large fluctuation of the pipe water flow to achieve water temperature monitoring. In addition, the water in the urban drainage network contains a large amount of impurities and pollutants, which are easily attached to the measurement probe, affecting the measurement accuracy, thereby reducing the reliability of temperature monitoring, and even breaking the wires under the action of the water flow, endangering the safety of the equipment.

[0004] In order to carry out the temperature monitoring work of the drainage system more stably, a sensitive and stable temperature monitoring probe is urgently needed to meet the observation needs of subtle temperature fluctuations under large water volume changes in the drainage network. Summary of the invention

[0046] The following is an explanation of the embodiments of the present disclosure by specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the information disclosed by the present disclosure. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in the present disclosure can also be modified or changed in various ways according to different viewpoints and application modules without departing from the spirit of the present disclosure. It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0047] The following is a detailed description of the embodiments of the present disclosure with reference to the accompanying drawings so that those skilled in the art can easily implement the present disclosure. The present disclosure can be embodied in many different forms and is not limited to the embodiments described herein.

[0048] like Figure 1 As shown, a schematic diagram of the structure of a floating ball for monitoring water temperature of a drainage network pipe is shown in the present disclosure. The floating ball for monitoring water temperature of a drainage network pipe includes: a top counterweight 1, a bottom counterweight 2, a float 3, a temperature probe 4, and a cable 5.

[0049] The top counterweight 1 is used to realize the side-lying floating of the drainage network water temperature monitoring floating ball.

[0050] Specifically, the material selection of the top weight 1 needs to consider its density, corrosion resistance, durability and environmental impact. The materials usually selected include but are not limited to lead, iron or other high-density alloys, which can not only effectively provide the required weight, but also have good corrosion resistance and are suitable for long-term immersion in water.

[0051] In actual application, the temperature probe is thrown into the inspection well with the cable. Due to the effect of the bottom counterweight, the temperature probe is ensured to be stably placed downward into the water. After entering the water, the temperature probe will not sink to the bottom due to the buoyancy, but will lie obliquely in the water due to the influence of the top counterweight. Under the impact of the water flow, the floating ball enters the pipeline driven by the water flow and starts measuring.

[0052] The bottom counterweight 2 cooperates with the top counterweight 1 to maintain the stability of the drainage network water temperature monitoring floating ball underwater.

[0053] Specifically, the bottom counterweight 2 cooperates with the top counterweight 1, and is designed to maintain the stability of the drainage network water temperature monitoring float ball after it sinks underwater. The bottom counterweight 2 provides a downward force to balance the buoyancy generated by the float 3, ensuring that the drainage network water temperature monitoring float ball remains horizontal or at a set inclination angle underwater. The design of the bottom counterweight 2 needs to consider its impact on the overall center of gravity of the drainage network water temperature monitoring float ball to achieve optimal stability and operational efficiency. The material selection of the bottom counterweight 2 should be based on high density and corrosion resistance. Commonly used materials include metals or alloys, which not only provide the necessary weight, but also can withstand the corrosion of the underwater environment to ensure long-term stability.

[0054] In some embodiments, the weight of the top counterweight 1 is smaller than that of the bottom counterweight 2 .

[0055] Specifically, the weight of the top counterweight 1 is designed to be less than the bottom counterweight 2. This design choice is intended to achieve optimal stability and posture control of the drainage network water temperature monitoring float ball underwater through weight distribution. The lightweight top counterweight 1 helps the drainage network water temperature monitoring float ball maintain flexibility and responsiveness during the sinking process and in the underwater environment. The weight ratio between the top counterweight 1 and the bottom counterweight 2 is carefully calculated, and the optimal ratio is 1:5 to ensure that the drainage network water temperature monitoring float ball can achieve an ideal suspension state in the water. The lightweight top counterweight 1 helps reduce resistance during the sinking process while maintaining sufficient weight to ensure that the device does not float excessively due to water flow disturbances.

[0056] Furthermore, the top counterweight 1 and the bottom counterweight 2 are both hemispherical, wherein the size of the top counterweight 1 is smaller than that of the bottom counterweight 2 .

[0057] Specifically, the top counterweight 1 and the bottom counterweight 2 are both designed to be hemispherical, which helps to reduce resistance in an underwater environment and improve the fluid dynamics of the drainage network water temperature monitoring float. The hemispherical structure can move more smoothly in the water flow and reduce eddies and turbulence caused by irregular shapes. The size of the top counterweight 1 is smaller than the bottom counterweight 2, and this size design is to achieve a specific weight distribution and stability. The smaller top counterweight 1 helps the drainage network water temperature monitoring float to maintain low resistance when sinking, while the larger bottom counterweight 2 provides sufficient downward force to maintain the vertical stability of the device. The size difference between the hemispherical top counterweight 1 and the bottom counterweight 2 directly affects the center of gravity position of the drainage network water temperature monitoring float. The smaller top counterweight 1 combined with the larger bottom counterweight 2 helps to keep the center of gravity at a lower position, thereby increasing the stability of the device. In addition, the larger size of the bottom counterweight 2 helps to provide a larger contact area underwater, which helps to increase the stability of the device under unstable underwater conditions, such as water flow disturbances or uneven pipe bottoms.

[0058] In order to prevent sediment and debris from accumulating on the surface of the bottom weight 2 and maintain the appearance and performance of the equipment, the following Figure 1 In some embodiments, a plurality of elliptical guide grooves 6 are provided on the surface of the bottom counterweight 2 .

[0059] Specifically, the design of the elliptical guide groove 6 helps the water flow through the bottom counterweight 2 more smoothly, reduces the generation of body-fitting eddies and turbulence, thereby reducing the additional resistance caused by the water flow and forming several mainstream flow channels. The distribution of the elliptical guide grooves 6 on the surface of the bottom counterweight 2 is carefully planned and may be arranged in a specific geometric pattern to achieve the best fluid dynamics and cleaning efficiency. The size and shape of each guide groove 6 are optimized to ensure that the structural integrity and weight distribution of the bottom counterweight 2 are not sacrificed while reducing resistance. The material selection and manufacturing process of the bottom counterweight 2 need to take into account the processing of the guide groove 6 to ensure that the edges of the holes are smooth and burr-free to avoid adding additional resistance. The presence of the guide groove 6 simplifies the cleaning and maintenance of the bottom counterweight 2, because the water flow can carry away sediment through the holes, reducing the need for manual cleaning.

[0060] The floating body 3 is arranged between the top counterweight 1 and the bottom counterweight 2, and is used to suspend the drainage network water temperature monitoring floating ball in the water body.

[0061] Specifically, the basic function of the design of the float 3 is to enable the drainage network water temperature monitoring floating ball to be stably suspended in the water body. By providing the necessary buoyancy, the float 3 ensures that the drainage network water temperature monitoring floating ball remains at a set depth underwater, which is convenient for temperature monitoring. The float 3 is arranged between the top counterweight 1 and the bottom counterweight 2 to form the main part of the drainage network water temperature monitoring floating ball. This layout allows the drainage network water temperature monitoring floating ball to maintain balance during the sinking process and underwater monitoring.

[0062] In some embodiments, the floating body 3 is a truncated cone structure, wherein the smaller radius end is fixed to the top counterweight 1, and the larger radius end is fixed to the bottom counterweight 2. The top counterweight, the floating body, and the bottom counterweight form a tumbler structure, so that the temperature probe exhibits a larger swing under the impact of the water flow, thereby strengthening the interaction between the temperature probe and the surrounding water body.

[0063] Specifically, this structure optimizes the buoyancy distribution and hydrodynamic characteristics of the float 3. The truncated cone design not only provides a smooth transition from the top counterweight 1 to the bottom counterweight 2, but also helps to reduce the resistance of the water flow to the floating ball for monitoring the water temperature of the drainage network. The smaller radius end of the truncated cone float 3 is fixedly connected to the top counterweight 1, while the larger radius end is fixedly connected to the bottom counterweight 2. The whole presents a tumbler structure, and the temperature probe can show a larger swing, further strengthening the interaction of the water body around the bottom probe and improving the sensitivity of the probe. In addition, this size design allows the float 3 to provide buoyancy while also helping to maintain the balance and stability of the floating ball for monitoring the water temperature of the drainage network. The connection method between the float 3 and the top counterweight 1 and the bottom counterweight 2 needs to ensure firmness and reliability. Possible connection technologies include mechanical fixation, bonding or welding to adapt to different materials and environmental conditions.

[0064] Furthermore, the material of the float 3 is a foam material, which is an ideal choice due to its light weight and high buoyancy. The foam material also has good chemical stability and durability, and is suitable for long-term immersion in an underwater environment. In addition, in order to facilitate cleaning, the surface of the float 3 can be coated with a smooth coating or specially treated to reduce the adhesion of sediments and improve the durability of the equipment.

[0065] In the above implementation, by setting the bottom counterweight and the top counterweight and maintaining a certain reasonable proportion, as well as the truncated cone design of the float, combined with the cable tension, the drainage network water temperature monitoring floating ball can maintain an inclined suspended state underwater, and even under complex water flow conditions, the temperature probe can be kept in the water, thereby enhancing the stability of the equipment; in the absence of water or low water level, affected by the overall center of gravity, the temperature probe can remain at the bottom of the pipe, and measure the water temperature as much as possible.

[0066] In order to reduce the resistance of water flow to the floating ball for monitoring water temperature in the drainage network pipe and improve its movement efficiency in the underwater environment, in some embodiments, such as Figure 2 As shown, a plurality of elliptical guide grooves 6 are provided on the surface of the floating body 3 .

[0067] Specifically, the design of the elliptical guide groove shows significant advantages in fluid dynamics. Compared with the traditional circular hole, the elliptical hole can significantly reduce the generation of turbulence and eddy current when the water flows through, thereby effectively reducing the resistance, which has been confirmed in the study of fluid dynamics. In the present disclosure, the size and number of the guide grooves 6 are carefully designed, and they are optimized according to the size, shape and required buoyancy of the float 3 to achieve the best fluid dynamic effect.

[0068] In addition, the distribution of the guide grooves 6 on the surface of the floating body 3 is also carefully arranged and arranged in a specific pattern. Such a design not only ensures that the resistance of the entire floating body 3 under water can be evenly increased, but also enhances the hydrodynamic performance and stability of the floating body. Through this optimized design, the elliptical guide grooves 6 can maintain the good stability of the floating body 3 while improving its movement efficiency and adaptability in the underwater environment.

[0069] In addition, the guide groove 6 not only increases the overall resistance, strengthens the effect of the temperature probe being carried by the water flow in the water body, ensures that the temperature probe always carries out measurement work along the direction of the water flow, reduces garbage mounting, and reduces the resistance at the guide groove. A close-fitting water flow can be formed at the groove of the guide groove to serve the subsequent vortex generation link.

[0070] The temperature probe 4 is fixed on the bottom counterweight 2 and is used to collect water temperature data in real time.

[0071] In some embodiments, the temperature probe 4 is fixed to the bottom of the bottom weight 2 to ensure direct contact with the water body.

[0072] Specifically, the temperature probe 4 is fixed to the bottom of the bottom counterweight 2 so that the probe can be in continuous contact with the water flow, and the water temperature can be accurately measured even in an environment where the water flow is slow or stagnant. The temperature probe 4 is designed to collect water temperature data in real time, which means that it can continuously monitor water temperature changes and provide immediate feedback to operation and maintenance managers. The stability of the bottom counterweight 2 provides a stable monitoring platform for the temperature probe 4, reducing measurement errors caused by equipment movement or shaking.

[0073] Furthermore, the temperature probe 4 and its fixing device are designed to take into account the durability of the underwater environment, and adopt corrosion-resistant materials and sealing technology to ensure long-term stable operation. The design and material selection of the probe are intended to provide high-precision measurement results, and can maintain accuracy even in environments with complex water quality or pollutants. The temperature probe 4 may be integrated with electronic components, such as sensors, signal amplifiers and converters, etc., for converting temperature signals into transmittable electrical signals.

[0074] The cable 5 is connected to the temperature probe 4, passes through the bottom counterweight 2, the floating body 3 and the top counterweight 1 in sequence, and is led out at the upper end of the top counterweight 1, so as to transmit the data collected by the temperature probe 4 to an external device.

[0075] Specifically, the cable 5 is designed to be connected to the temperature probe 4 to ensure accurate transmission of the water temperature data collected by the probe. This connection usually uses a sealed and waterproof connector to ensure the stability and reliability of data transmission. The cable 5 sequentially penetrates the bottom counterweight 2, the float 3 and the top counterweight 1, so that it can be arranged along the length direction of the drainage network water temperature monitoring float ball. This design reduces the flow resistance of the cable 5 in the water and protects the cable 5 from external physical damage. The material selection of the cable 5 takes into account water resistance, chemical corrosion resistance and electrical insulation. Special plastics or rubber may be used as the outer jacket, and the internal wire may be made of copper or other materials with good electrical conductivity. Furthermore, the design of the cable 5 takes into account compatibility with different types of monitoring equipment and data loggers to ensure that it can be used with a variety of data receiving systems.

[0076] In some embodiments, Figure 2 The cable 5 is bendable and is used to adapt to different inspection environments.

[0077] Specifically, this design allows the cable 5 to flexibly adapt to different inspection environments. The bendable cable 5 can reduce stress during installation and allow the cable 5 to be smoothly arranged in uneven or irregular inspection wells and pipelines. The bendable nature of the cable 5 enables it to adapt to a variety of inspection environments, including narrow or curved pipelines. This design improves the convenience of the installation process and reduces physical damage to the cable 5.

[0078] In some embodiments, the connection point between the cable 5 and the top weight 1 is designed as a rotating joint so that the cable 5 can rotate freely according to the water flow.

[0079] Specifically, the connection point between the cable 5 and the top counterweight 1 adopts a rotary joint design, which allows the cable 5 to rotate freely under the influence of water flow. The rotary joint provides additional flexibility and reduces the kinking or excessive stretching of the cable 5 caused by the water flow. Furthermore, the structural design of the rotary joint must ensure that while allowing rotation, it also has sufficient mechanical strength to withstand the tension and pressure that may be generated in the underwater environment. The rotary joint must have good sealing performance to prevent moisture from invading the interior of the cable 5 and affecting the quality of data transmission and the reliability of the equipment.

[0080] In some embodiments, the drainage network water temperature monitoring floating ball also includes a bearing, which is arranged between the float and the probe and the cable, allowing the float to rotate freely around the probe and the cable; wherein, under the action of gravity, the float can roll to the bottom of the drainage network when the water level drops, so as to maintain the contact between the temperature probe and the water body.

[0081] like Figure 3 As shown, in some embodiments, a plurality of vortex generators 7 with protruding corners are provided on the bottom counterweight, the protruding ends of the vortex generators are aligned with the center lines of the elliptical guide grooves, the tips of the corners point in the direction of the temperature sensor, and the vortexes generated by the vortex generators point to the temperature probe.

[0082] Specifically, a vortex generator 7 is integrated on the bottom counterweight, and the generator is composed of a plurality of protruding angle bodies 71. These protruding angle bodies 71 are based on the flow effect behind the column, that is, when the fluid flows through these specially designed protruding angle bodies 71, a vortex area will be formed behind them. These vortices not only promote the local mixing of the water flow, but also improve the water flow dynamics characteristics of the monitoring area, which helps to obtain more accurate and representative water temperature measurement results.

[0083] In addition, in order to maintain the long-term stability and cleanliness of the vortex generator, the tips of all corners are smoothed. This smooth design effectively reduces the adhesion of particles and sediment in the water flow.

[0084] In some embodiments, Figure 4 The bottom view of the floating ball for monitoring the water temperature of the drainage network pipe is shown, and a plurality of fins 8 are provided on the bottom counterweight, and each fin 8 has a specific geometric shape and size and is oriented at a preset angle relative to the bottom counterweight.

[0085] Exemplarily, two fins 8 are provided on the bottom counterweight, and the two fins 8 are arranged at an angle of 90°. Such a layout not only optimizes the dynamic characteristics of the water flow, but also promotes the mixing of the water flow around the temperature probe, reduces the temperature gradient, and improves the uniformity and accuracy of the temperature measurement.

[0086] The design of the centrally symmetrically distributed fin structure can restrain and concentrate the vortex generated by the vortex generator.

[0087] In order to better illustrate the above-disclosed water monitoring floating ball, an example will be listed below to fully describe the working process of the water monitoring floating ball in the city's sewer network.

[0088] like Figure 5 As shown in the figure, when the floating ball is dropped into the city's sewer network, the weight of the top counterweight is set greater than the bottom counterweight to ensure that the floating ball can quickly sink to the depth of the water body required for monitoring. During the sinking process, the cooperation between the top counterweight and the bottom counterweight not only promotes the sinking, but also provides the necessary stability for the floating ball underwater. The larger size and weight ratio of the bottom counterweight plays a key role. The downward force it generates effectively resists buoyancy and possible water flow disturbances.

[0089] The float located between the top counterweight and the bottom counterweight adopts a truncated cone structure design, with the smaller radius end fixed to the top counterweight and the larger radius end fixed to the bottom counterweight. This design not only provides buoyancy, but also ensures the stable suspension of the floating ball in the water. The elliptical guide grooves on the surface of the float and the bottom counterweight further improve the stability and cleaning efficiency of the floating ball by reducing water flow resistance and sediment accumulation.

[0090] A vortex generator is specially integrated on the bottom counterweight. The device consists of multiple angular fins, each of which has a specific geometry and size and is oriented at a preset angle. The design of these fins is based on the principles of fluid dynamics, especially the flow effect behind the column, which can effectively disturb the water flow and generate vortices, thereby enhancing the water flow mixing and heat exchange intensity in the area around the temperature probe. The design of this vortex generator not only improves the monitoring accuracy, but also reduces the possible adhesion of sediments through the smoothed angular tip.

[0091] The drainage network water temperature monitoring floating ball swings in the water, and the temperature probe is fixed to the bottom of the bottom counterweight, directly in contact with the water body, and can accurately collect water temperature data in real time. The cable connects the temperature probe, passes through the various components of the floating ball, and is led out from the top of the top counterweight to transmit the collected data to the external device. The bendable design of the cable and the application of the rotating joint enable it to adapt to different inspection environments and maintain the continuity and stability of data transmission, and it can remain flexible and reliable even in complex underwater environments.

[0092] In summary, the present disclosure provides a drainage network water temperature monitoring floating ball, including key components such as a top counterweight, a bottom counterweight, a float, a temperature probe and a cable. The top counterweight and the bottom counterweight are designed with precise weight ratios to ensure the stability and sinking performance of the drainage network water temperature monitoring floating ball underwater. The float adopts a truncated cone structure and is made of lightweight foam material to provide the necessary buoyancy to maintain the suspension state of the drainage network water temperature monitoring floating ball. The temperature probe is fixed to the bottom of the bottom counterweight and is in direct contact with the water body to achieve real-time water temperature data collection. The cable is designed to be bendable and connected to the top counterweight through a rotating joint to ensure the reliability of data transmission and the flexibility to adapt to different inspection environments. In addition, the elliptical guide groove design on the surface of the drainage network water temperature monitoring floating ball, the vortex generator on the bottom counterweight and the fin design can enhance the turbulence of the flow field near the temperature probe through the pipeline hydraulic impact in the absence of power, thereby improving the thermal sensitivity of the temperature probe.

[0093] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure. 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 disclosure shall still be covered by the claims of the present disclosure.
