Description

Technical Field

[0001] This utility model relates to the field of ecological governance system technology, and in particular to an ecological environment analysis system based on the pollution level of urban rivers. Background Technology

[0002] Urban rivers are not only an important part of the urban landscape, but also have a very close relationship with the daily lives of urban residents. They are also an important component of the ecological environment. Therefore, it is necessary to manage and maintain rivers from the perspective of ecological environmental protection in order to improve the existing pollution situation of urban rivers. However, in the process of urban modernization, many factories along the river discharge industrial wastewater directly into urban rivers in order to save on sewage treatment costs, resulting in the turbidity of the rivers exceeding the standard.

[0003] The existing method for detecting pollution levels in urban rivers involves setting up pollution detection base stations at intervals along the river, collecting the data detected by the pollution detection base stations to a control terminal, and then analyzing the data by monitoring the turbidity of the water flow in each section of the river to determine whether there is a sudden change in water turbidity in the corresponding river section. This allows for early warning, reminding monitoring personnel to investigate factories along the river section and crack down on industrial wastewater discharge.

[0004] The common operating method for existing pollution detection base stations to detect water quality is to insert the sensor of the detection device into the water source, analyze the corresponding water turbidity data through the detection equipment, and then upload it to the terminal. However, in actual application, it has been found that the sensor is prone to algae growth after being immersed in water for a long time, which reduces the accuracy of the detection data and affects the actual detection results. Utility Model Content

[0005] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and other accompanying drawings.

[0006] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an ecological environment analysis system based on urban river pollution levels. A liftable telescopic rotating assembly is installed on the base station. This assembly controls the depth of the sensor probe within the cleaning frame, allowing the sensor probe to be in different states. When the sensor probe moves under the control of the lifting assembly, it can be used to measure water turbidity at different depths. When cleaning is required, the telescopic rod controls the sensor probe to extend deeper into the cleaning frame and contact the cleaning brush. A rotary motor drives the sensor probe to rotate, cleaning the probe and removing algae and organisms. When the entire cleaning frame needs to be lifted and replaced, the telescopic rod extends further, causing the limiting rod on the side of the sensor probe to engage with the bottom of the cleaning frame. Simultaneously, the lifting assembly raises the sensor probe, allowing the cleaning frame to be carried out of the water.

[0007] This utility model provides an ecological environment analysis system based on urban river pollution levels, including an analysis and control terminal and a detection base station electrically connected to the analysis and control terminal. The detection base station is equipped with a water turbidity detection device, which includes a lifting assembly, a telescopic rotating assembly, a cleaning frame, and a water turbidity detector. The top of the lifting assembly is fixed to the detection base station, and the bottom of the lifting assembly is fitted with the cleaning frame. Several cleaning brushes are provided on the bottom surface of the cleaning frame. The telescopic rotating assembly, which can be raised and lowered, extends from the lifting assembly. The water turbidity detector is located at the end of the telescopic rotating assembly and is located inside the cleaning frame, abutting against the cleaning brushes on the bottom surface.

[0008] The detection base stations and their water turbidity detection devices along the route are used to detect water turbidity data in urban rivers. After the water turbidity data from multiple detection base stations are collected and sent to the analysis and control terminal, it is determined whether there is a sudden change in water turbidity in the corresponding river section, thereby issuing an early warning and reminding monitoring personnel to investigate factories along the river section. The water turbidity detection device is equipped with a water turbidity detector that is inserted into the river water to obtain water turbidity data. The lifting component is used to control the lifting of the water turbidity detector to adapt to the river water level and to detect the differences in water turbidity at different depths in the river. The lifting component and the water turbidity detector are connected by a telescopic rotating component, which allows the water turbidity detector to extend, retract, and rotate. After contacting the cleaning brush set on the bottom, the rotating friction cleans the algae and parasitic organisms attached to the detector probe, improving the accuracy of the detection data. It should be understood that the detection base stations and the analysis and control terminal can be electrically or communicatively connected. The part that collects data and performs analysis and early warning involves software programming, which is well known to those skilled in the art. Only its implementation function is briefly described here. For specific information on the distribution planning and program settings of the base stations, please refer to the existing technology.

[0009] In some embodiments, the lifting assembly includes a fixed base, a protective tube, a lifting screw, and a lifting motor. The fixed base is connected to the detection base station by bolts. The lifting motor is mounted on the fixed base, and the protective tube extends from the lower side of the fixed base. The lifting screw is located inside the protective tube. The lifting motor passes through the fixed base and connects to the lifting screw, driving the lifting screw to rotate. The vertically arranged lifting assembly is used to control the lifting and lowering of the water turbidity detector, allowing it to penetrate the water and detect the turbidity data of the river. The fixed base, located at the top of the lifting assembly, is used to fix the position of the entire water turbidity detection device, connecting it to the cement platform of the base station. The extended protective tube is fitted around the lifting screw, providing protection for the lifting screw. Driven by the lifting motor, the support plate screwed onto the lifting screw can move up and down, thereby causing the components fixed to the support plate to move together.

[0010] In some embodiments, a movable groove is provided on the side of the protective tube, through which the protective tube communicates with the outside. A support plate is screwed onto the lifting screw, and the support plate extends to the outside of the protective tube through the movable groove. The telescopic rotating assembly is vertically arranged on the lower side of the support plate. The support plate is used to install the telescopic rotating assembly. The movable groove connects the inside and outside of the protective tube, allowing the support plate to move up and down under the drive of the lifting screw. At the same time, the movable groove also guides the movement path of the support plate.

[0011] In some embodiments, the telescopic rotating assembly includes a telescopic rod, a telescopic motor, and a rotary motor. The fixed end of the telescopic rod is connected to the support plate, and the telescopic motor is also connected to the support plate and located on one side of the telescopic rod. The movable end of the telescopic rod is connected to the rotary motor. The telescopic rotating assembly is positioned between the lifting assembly and the water turbidity detector, enabling the water turbidity detector to perform telescopic rotation. When cleaning the probe of the water turbidity detector is required, the telescopic rotating assembly and the sensor probe are lowered and engaged in the cleaning frame, causing the bottom of the sensor probe to contact the cleaning brush. The rotary motor is then activated, causing the sensor probe to rotate, thereby achieving the cleaning function.

[0012] In some embodiments, the water turbidity detector includes a sensor probe. The upper side of the rotary motor is connected to the telescopic rod, and the lower side of the rotary motor is connected to the sensor probe. Two limiting rods extend from both sides of the bottom of the sensor probe. The limiting rods extending from both sides of the bottom of the sensor probe are used to engage with a fastening groove. Driven by the telescopic rod, the sensor probe continues to extend and passes through the fastening groove. After rotating a certain angle, the limiting rods abut against the bottom side of the cleaning frame. At this time, the lifting assembly is driven to lift, which can lift the cleaning frame out of the water surface together, for periodic replacement of the cleaning frame and its cleaning brush.

[0013] In some embodiments, a limiting ring extends outward from the end of the protective tube. The cleaning frame includes a retaining collar and a positioning cylinder connected to the side of the retaining collar. The retaining collar is fitted over the outside of the protective tube and abuts against the limiting ring. The positioning cylinder is located on the side of the protective tube and extends upward. The limiting ring cooperates with the retaining collar to fix the position of the cleaning frame, while the positioning cylinder accommodates the telescopic rotating assembly and the sensor probe, limiting the rotation range of the sensor probe.

[0014] In some embodiments, a balancing hole is provided at the bottom of the positioning cylinder, and several cleaning brushes are arranged in a ring around the balancing hole at intervals. The bottom of the sensor probe abuts against the cleaning brushes. The balancing hole is used to balance the pressure difference inside and outside the cylinder. During the lifting and lowering of the cleaning frame, the water pressure changes rapidly. Adding holes to the bottom surface facilitates water flow and reduces resistance. At the same time, the balancing hole also provides a reserved position for the sensor probe to extend.

[0015] In some embodiments, the balance hole extends outward and is provided with two engaging grooves, which are arranged opposite each other and the depth of the engaging grooves is adapted to the length of the limiting rod. The limiting rod extends out of the cleaning frame through the engaging grooves. After rotating a certain angle, the telescopic rod retracts, and the limiting rod abuts against the bottom, thereby driving the cleaning frame to rise together.

[0016] In some embodiments, the side of the positioning cylinder may be a plurality of steel rings spaced apart or a filter screen arranged around it. In order to reduce the internal and external pressure difference and reduce the overall weight of the cleaning frame, the side of the positioning cylinder is a spaced ring structure or a filter screen arranged around it. Preferably, the steel rings and the filter screen are coated with waterproof paint to prevent biofouling.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are:

[0018] This invention features a liftable telescopic rotating assembly on the base station. This assembly controls the depth of the sensor probe within the cleaning frame, allowing the probe to be in different states. When the sensor probe moves under the control of the lifting assembly, it can be used to measure water turbidity at different depths. When cleaning is required, the telescopic rod guides the probe deeper into the cleaning frame and into contact with the cleaning brush. A rotating motor drives the probe to rotate, cleaning the probe and removing algae and organisms. When the entire cleaning frame needs to be lifted and replaced, the telescopic rod extends further, causing the limiting rod on the side of the sensor probe to engage with the bottom of the cleaning frame. Simultaneously, the lifting assembly raises the sensor probe, allowing the cleaning frame to be carried out of the water.

[0046] According to some embodiments of the present invention, the present invention provides an ecological environment analysis system based on urban river pollution levels, including an analysis and control terminal 1 and a detection base station 2 electrically connected to the analysis and control terminal 1. The detection base station 2 is equipped with a water turbidity detection device 3, which includes a lifting component 31, a telescopic rotating component 32, a cleaning frame 33, and a water turbidity detector 34. The top of the lifting component 31 is fixed to the detection base station 2, and the bottom of the lifting component 31 is fitted with the cleaning frame 33. Several cleaning brushes 334 are provided on the bottom surface of the cleaning frame 33. The telescopic rotating component 32, which can be raised and lowered, extends from the lifting component 31. The water turbidity detector 34 is provided at the end of the telescopic rotating component 32. The water turbidity detector 34 is located inside the cleaning frame 33 and abuts against the cleaning brushes 334 on the bottom surface.

[0047] The detection base stations 2 and their water turbidity detection devices 3 set up along the route are used to detect water turbidity data in urban rivers. After the water turbidity data from multiple detection base stations 2 are collected and sent to the analysis and control terminal 1, it is determined whether there is a sudden change in water turbidity in the corresponding river section, thereby issuing an early warning and reminding monitoring personnel to investigate factories along the river section. The water turbidity detection device 3 is equipped with a water turbidity detector 34 that is inserted into the river water to obtain water turbidity data. The lifting component 31 is used to control the lifting of the water turbidity detector 34 to adapt to the river water level and to detect the differences in water turbidity at different depths in the river. The lifting component 31 and the water The turbidity detectors 34 are connected by a telescopic rotating assembly 32, allowing the water turbidity detectors 34 to extend and rotate. After contacting the cleaning brush 334 on the bottom surface, the rotating friction cleans the algae and parasitic organisms attached to the detector probe, improving the accuracy of the detection data. It should be understood that the detection base station 2 and the analysis and control terminal 1 can be electrically or communicatively connected. The part that collects, analyzes, and issues warnings involves software programming, which is well known to those skilled in the art. Here, only its implementation function is briefly described. For specific information on the distribution planning and program settings of the base stations, please refer to the existing technology.

[0048] The lifting assembly 31 includes a fixed base 311, a protective tube 312, a lifting screw, and a lifting motor 313. The fixed base 311 is connected to the detection base station 2 by bolts. The lifting motor 313 is installed on the fixed base 311. The protective tube 312 extends from the lower side of the fixed base 311. The lifting screw is located inside the protective tube 312. The lifting motor 313 passes through the fixed base 311 and connects to the lifting screw, driving the lifting screw to rotate. The vertically arranged lifting assembly 31 is used to control the lifting and lowering of the water turbidity detector 34, so that it can be inserted into the water and detect the turbidity data of the river. The fixed base 311 set on the top of the lifting assembly 31 is used to fix the position of the entire water turbidity detection device 3, so that it is connected to the cement platform of the base station. The extended protective tube 312 is sleeved around the lifting screw, which plays a protective role for the lifting screw. Driven by the lifting motor 313, the support plate 315 screwed on the lifting screw can move up and down, thereby driving the components fixed on the support plate 315 to move together.

[0049] The protective tube 312 has a movable groove 314 on its side, through which the inside and outside of the protective tube 312 are connected. A support plate 315 is screwed onto the lifting screw, and the support plate 315 extends to the outside of the protective tube 312 through the movable groove 314. The telescopic rotating assembly 32 is vertically arranged on the lower side of the support plate 315. The support plate 315 is used to install the telescopic rotating assembly 32. The movable groove 314 connects the inside and outside of the protective tube 312, allowing the support plate 315 to move up and down under the action of the lifting screw. At the same time, the movable groove 314 also guides the movement path of the support plate 315.

[0050] Reference Figure 4 , Figure 4 This is a schematic diagram showing the cooperation between the telescopic rotating component and the cleaning frame in some embodiments of this utility model.

[0051] According to some embodiments of this utility model, optionally, the telescopic rotating assembly 32 includes a telescopic rod 321, a telescopic motor 322, and a rotating motor 323. The fixed end of the telescopic rod 321 is connected to the support plate 315, and the telescopic motor 322 is also connected to the support plate 315 and located on one side of the telescopic rod 321. The movable end of the telescopic rod 321 is connected to the rotating motor 323. The telescopic rotating assembly 32 is disposed between the lifting assembly 31 and the water turbidity detector 34, enabling the water turbidity detector 34 to perform telescopic and rotating functions. When it is necessary to clean the probe of the water turbidity detector 34, the telescopic rotating assembly 32 and the sensor probe 341 are controlled to descend and engage in the cleaning frame 33, so that the bottom of the sensor probe 341 contacts the cleaning brush 334. The rotating motor 323 is then started, causing the sensor probe 341 to rotate, thereby achieving the cleaning function.

[0052] The water turbidity detector 34 includes a sensor probe 341. The upper side of the rotary motor 323 is connected to the telescopic rod 321, and the lower side of the rotary motor 323 is connected to the sensor probe 341. Two limiting rods 342 extend from the bottom sides of the sensor probe 341. The limiting rods 342 extending from the bottom sides of the sensor probe 341 are used to cooperate with the fastening groove 335. Driven by the telescopic rod 321, the sensor probe 341 continues to extend and passes through the fastening groove 335. After rotating a certain angle, the limiting rods 342 abut against the bottom side of the cleaning frame 33. At this time, the lifting assembly 31 is driven to lift, which can lift the cleaning frame 33 out of the water surface together, for periodically replacing the cleaning frame 33 and the cleaning brush 334 on it.

[0053] The protective tube 312 extends outward at its end with a limiting ring. The cleaning frame 33 includes a fixing collar 331 and a positioning cylinder 332 connected to the side of the fixing collar 331. The fixing collar 331 is fitted onto the outside of the protective tube 312 and abuts against the limiting ring. The positioning cylinder 332 is located on the side of the protective tube 312 and extends upward. The limiting ring is used to cooperate with the fixing collar 331 to fix the position of the cleaning frame 33, while the positioning cylinder 332 is used to accommodate the telescopic rotating assembly 32 and the sensor probe 341, limiting the rotation range of the sensor probe 341.

[0054] The positioning cylinder 332 has a balance hole 333 at its bottom. Several cleaning brushes 334 are arranged in a ring around the balance hole 333 at intervals around the bottom of the positioning cylinder 332. The bottom of the sensor probe 341 abuts against the cleaning brushes 334. The balance hole 333 is used to balance the pressure difference inside and outside the cylinder. During the lifting and lowering of the cleaning frame 33, the water pressure changes rapidly. Adding holes on the bottom surface can facilitate water flow and reduce resistance. At the same time, the balance hole 333 also provides a reserved position for the sensor probe 341 to extend.

[0055] The balance hole 333 extends outward and is provided with two fastening grooves 335. The two fastening grooves 335 are arranged opposite each other and the depth of the fastening grooves 335 is adapted to the length of the limiting rod 342. The limiting rod 342 extends out of the cleaning frame 33 through the fastening grooves 335. After rotating a certain angle, the telescopic rod 321 retracts and the limiting rod 342 abuts against the bottom, thereby driving the cleaning frame 33 to rise together.

[0056] The side of the positioning cylinder 332 may be composed of several steel rings connected at intervals or a filter screen arranged around it. In order to reduce the internal and external pressure difference and reduce the overall weight of the cleaning frame 33, the side of the positioning cylinder 332 is a ring structure arranged at intervals or a filter screen arranged around it. Preferably, the steel rings and the filter screen are coated with waterproof paint to prevent biological parasites.
