Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage treatment, in particular to a replaceable environmental monitoring device and a multi-protocol compatible telemetry terminal. BACKGROUND

[0002] In the field of sewage treatment, water quality monitoring is a core link to ensure efficient operation of the treatment process and standard discharge of effluent. Environmental monitoring devices collect real-time data on key parameters such as pH, COD, ammonia nitrogen, and suspended solids, providing data support for process control and equipment operation and maintenance in sewage treatment plants. However, existing environmental monitoring devices for sewage treatment have significant technical bottlenecks in long-term operation:

[0003] On the one hand, the complex composition of sewage (such as high-concentration suspended solids, acid-base pollutants, and corrosive ions) easily causes the failure of monitoring sensors. For example, the surface of a pH glass electrode is easily attached by grease or biofilm, causing the detection value to drift; the flow cell of a COD sensor is often blocked by suspended solids, making it impossible to sample normally; and chlorine ion-containing sewage causes electrochemical corrosion of the ammonia nitrogen electrode made of metal, resulting in a sensor life of only 3-6 months. Existing devices are mostly fixedly installed, and replacing sensors requires shutting down, disassembling the pipeline, disconnecting the signal line, and recalibrating, which takes 2-4 hours per maintenance and requires operators to wear protective equipment to handle contaminated parts, accounting for 40%-60% of the total life cycle cost of the equipment. SUMMARY

[0004] The present application aims to provide a replaceable environmental monitoring device and a multi-protocol compatible telemetry terminal to solve the problem of fixed detection position and cumbersome maintenance of traditional equipment as described in the background.

[0005] The technical solution adopted by the present application is as follows: a replaceable environmental monitoring device that automatically switches between detection and replacement positions of water quality sensors through a guide groove-guide wheel linkage mechanism. Specifically, a servo motor drives a synchronous belt to move a bearing seat along a first guide rail, causing a guide wheel to roll in a V-shaped first guide groove, and then switching a water quality sensor on an execution arm between detection and replacement positions. The two sides work synchronously through a clamping plate linkage to achieve "one detection and one replacement".

[0006] The execution arm has a three-section structure composed of a square section, an oblique section, and a vertical section. When the guide wheel enters the second vertical section outside the guide groove, the oblique section drives the vertical section to deviate from the axis of the base plate, avoiding motion interference between the two execution arms. The base plate is installed with symmetrical tracks and position sensors to detect the differential signal generated in the sensor coil when the core moves with the bearing seat, achieving micron-level positioning calibration and solving the problem of open-loop control error of the servo motor.

[0007] The support is provided with a third guide rail and a bidirectional threaded screw rod, the second motor drives the third sliding table to adjust the spacing of the clamping arms, the water quality sensor vertical height is adjusted by cooperating with the sleeve base magnetic attraction positioning and the centering clamping mechanism, the water sampling pipe side wall equidistant water holes are linked with the water collecting ring extrusion blocks, the water passage is opened layer by layer to collect water samples of different water layers and form laminar flow, and the layered water quality detection precision is improved; in addition, the take-up mechanism uniformly takes up and releases the sensor line through the reciprocating screw rod sliding table to avoid winding and wear, the nozzle seat and the sealing ring wedge-shaped cooperation realize high-pressure cleaning of the water sampling pipe, the end cover one-way valve and the valve core traction rope mechanism are linked to discharge impurities, and the manual maintenance frequency is reduced.

[0008] A multi-protocol compatible telemetry terminal applying the replaceable environmental monitoring device, a terminal core data processing unit, an industrial-grade 32-bit MCU, a built-in multi-protocol analysis engine, an integrated isolation protection circuit, a wireless communication module, an RS485 communication module and a Beidou short message dual-channel, supporting encrypted transmission and breakpoint transmission, a display module, an ultra-low power consumption LCD and integrated ambient light sensing, a power supply system, lithium sub-battery and lithium iron phosphate battery dual energy, combined with solar charging and super capacitor, a terminal shell, IP67 protection level, supporting multiple installation modes, and an expansion function module, integrated edge computing engine and supporting OTA upgrade.

[0045] As Figures 1-3As shown, embodiment one, a replaceable environment monitoring device, including a base plate 1, the upper end face of the base plate 1 is fixed with a first guide rail 2 through a bolt, the number of the first guide rail 2 is 2, the 2 first guide rails 2 are arranged symmetrically in parallel; The first guide rail 2 is slidably connected with the first sliding table 3; The first sliding table 3 is installed with the bearing seat 4; The bearing seat 4 is provided with a notch 5, the shape of the notch 5 is U type; The bearing seat 4 is fixed with a second guide rail 6 through a bolt, the number of the second guide rail 6 is 2, the 2 second guide rails 6 are slidably connected with the second sliding table 7, the sliding direction of the second sliding table 7 is perpendicular to the sliding direction of the first sliding table 3; The second sliding table 7 is fixed with an execution arm 8 through a bolt, the execution arm 8 is installed with a support 9, the support 9 is installed with a water quality sensor 10, the water quality sensor 10 can be any one of conductivity probe, pH detection probe, turbidity detection probe, temperature detection probe; The execution arm 8 is installed with a shaft 11, the shaft 11 is rotatably connected with a guide wheel 12, the shaft 11 moves horizontally in the notch 5; The base plate 1 is provided with two symmetrically arranged first guide grooves 13, the first guide groove 13 is located on the outer side of the first guide rail 2, the shape of the first guide groove 13 is V type, the guide wheel 12 is in rolling contact with the first guide groove 13, so as to adjust the position of the water quality sensor 10 on the execution arm 8, when the bearing seat 4 moves to the lower end of the first guide groove 13, the water quality sensor 10 on the execution arm 8 starts to detect (as a detection position), when the bearing seat 4 moves to the upper end of the first guide groove 13, the water quality sensor 10 on the execution arm 8 starts to replace (as a replacement position); Specifically, the first guide groove 13 contains a first vertical section, a first inclined section, a second vertical section, a second inclined section and a third vertical section from top to bottom, the first vertical section is the same as the third vertical section, the second vertical section is located on the outer side of the first vertical section, and the first inclined section and the second inclined section are symmetrical in inclination direction; The bearing seat 4 is fixed with a first clamping plate 14 through a bolt, the base plate 1 is provided with two symmetrically arranged second guide grooves 15, the second guide groove 15 is located on the inner side of the first guide rail 2, the first clamping plate 14 passes through the second guide groove 15, and the first clamping plate 14 passing through the second guide groove 15 is connected with a second clamping plate 16 through a bolt; The base plate 1 is installed with a first motor 17, the first motor 17 is a servo motor, the first motor 17 is located on the upper side of the first guide rail 2, the shaft end of the first motor 17 is installed with a first pulley 18, and the base plate 1 has a shaft hole through which the first pulley 18 passes; The base plate 1 is installed with a first bearing seat 19, the first bearing seat 19 is located on the lower side of the first guide rail 2, the first bearing seat 19 is installed with a second pulley 20, the base plate 1 has a shaft hole through which the second pulley 20 passes, and a synchronous belt 21 is installed between the second pulley 20 and the first pulley 18, the synchronous belt 21 is clamped and fixed through the first clamping plate 14 and the second clamping plate 16, when one side of the first clamping plate 14 is located at the detection position of the first guide groove 13, the other side of the first clamping plate 14 is located at the replacement position of the first guide groove 13.

[0046] Movement Process: The first motor 17 (servo motor) drives the first pulley 18 to rotate, which in turn drives the second pulley 20 to rotate via the synchronous belt 21. The synchronous belt 21 is clamped and fixed by the first clamping plate 14 and the second clamping plate 16, thereby pulling the support seat 4 to move along the first guide rail 2. When the support seat 4 moves, the shaft 11 of the actuator arm 8 drives the guide wheel 12 to roll in the V-shaped first guide groove 13. When the guide wheel 12 moves downward along the first guide groove 13, the lateral displacement of the guide wheel 12 is transmitted to the actuator arm 8 through the shaft 11, causing the actuator arm 8 to move towards the axis of the substrate 1 and finally reach the detection position, where the water quality sensor 10 is immersed in the detection point. When the guide wheel 12 moves upward, the guide wheel 12 moves laterally in the opposite direction, and the actuator arm 8 moves away from the axis of the substrate 1 and reaches the replacement position, which is convenient for disassembling or installing the sensor. Since the first clamping plates 14 on both sides are linked in opposite directions by the synchronous belt 21, when one actuator arm 8 is in the detection position, the other side must be in the replacement position, realizing the automatic switching of the "detection-replacement" station.

[0047] Beneficial effects: Through the cooperation of the synchronous belt 21 and the guide groove, automatic switching between detection and replacement stations can be achieved without a complex control system, improving operation and maintenance efficiency and reducing manual intervention. Utilizing the rolling contact between the guide wheel 12 and the V-shaped guide groove, linear motion is converted into lateral fine-tuning of the actuator arm 8, resulting in a compact structure and high guiding accuracy, avoiding the backlash error of traditional lead screw and nut mechanisms. The water quality sensor 10 is fixed to the support 9 with bolts; replacement only requires removing the bolts at the replacement location. Combined with the dual-station design, sensor maintenance can be completed without interrupting detection, improving equipment continuity.

[0048] like Figure 4 As shown, as an optimization of Embodiment 1, considering that the detection data will be more accurate if the replacement positions of the two water quality sensors 10 are consistent, the actuator 8 is composed of a square segment 22, a diagonal segment 23, and a vertical segment 24 arranged from top to bottom. The square segment 22 is connected to the second slide table 7, and the vertical segment 24 is located on the plane where the axis of the substrate 1 is located. When the guide wheel 12 enters the second vertical segment, the actuator 8 deviates from the plane where the axis of the substrate 1 is located, so as to avoid structural interference between the two actuators 8.

[0049] Movement process: When the guide wheel 12 is located in the first vertical section or the third vertical section of the first guide groove 13, the vertical line segment 24 is located on the plane where the axis of the substrate 1 is located, and the actuator arm 8 is vertically downward, in the initial or reset state. When the guide wheel 12 enters the second vertical section (outer vertical section), the tilt angle of the oblique line segment 23 causes the vertical line segment 24 to deviate from the axis of the substrate 1, and the actuator arms 8 on both sides shift outward to avoid collision and interference between the two actuator arms 8 during movement.

[0050] Beneficial effect: through the geometric shape design (the inclination angle of the oblique line segment 23), the execution arm 8 is automatically deviated from the axis in the key movement stage (such as when passing through the second vertical segment), solving the problem of double execution arms 8 collision in the traditional parallel slide rail mechanism, allowing the device to be compactly laid out, improving space utilization. Without additional limiting devices, interference prevention is achieved only through the structure shape, reducing mechanical part wear and tear and reducing the probability of failure.

[0051] As shown in Figure 4 and Figure 5 As an optimization of Embodiment One, considering that the first motor 17 controls the movement position of the execution arm 8 through rotation turns and forward and reverse rotation, there is a problem of poor accuracy, the base plate 1 is fixed with a track 25 through a bolt, the number of tracks 25 is 2, the two tracks 25 are symmetrically arranged, and a position sensor 26 is fixed on the track 25 through a positioning bolt. The upper position sensor 26 is located at the replacement position of the water quality sensor 10, and the lower position sensor 26 is located at the detection position of the water quality sensor 10; the first clamping plate 14 is fixed with a detection iron core 27 through a bolt, the displacement of the detection iron core 27 in the coil of the position sensor 26 causes the secondary coil voltage to change, and outputs a differential signal proportional to the displacement, which is suitable for high-precision linear measurement.

[0052] Beneficial effect: based on the position detection technology of electromagnetic induction principle (detection iron core 27 cooperates with coil), compared with the traditional photoelectric switch, the positioning accuracy can reach microns, solving the cumulative error problem of open-loop control of servo motor, ensuring that the sensor stops at the same position each time. Electromagnetic induction detection is not affected by environmental light and dust, suitable for complex scenes such as outdoor sewage monitoring, improving the reliability of the device.

The movement of the plug 66 makes the second slope surface 68 separate from the first slope surface 65 of the water inlet hole 64, and the water passage 67 is aligned with the water inlet hole 64. The sewage passes through the water passage 67 into the sampling pipe 61, and flows into the laminar flow inlet hole 74 through the annular water distribution groove 73, forming a stable laminar flow. When the water collecting ring 72 stays at different heights, the water inlet hole 64 of the corresponding layer is opened, and the water quality sensor 10 extends into the sampling pipe 61 through the central through hole of the hexagonal seat 70 to detect the water sample of the layer.

[0058] Beneficial effect: through the mechanical linkage of the water collecting ring 72 and the plug 66, independent sampling of different depth water layers is realized, avoiding data fluctuation caused by water quality stratification in traditional single-point detection, especially suitable for vertical water quality analysis of static sewage tank. The design of the annular water distribution groove 73 and the laminar flow inlet hole 74 makes the water sample enter the detection area in a laminar flow state, reducing the impact of turbulent flow on the sensor and improving the detection stability of parameters such as turbidity and conductivity.

[0059] As shown in Figure 22 As an optimization of Example Two, considering that the line of the water quality sensor 10 needs to be smoothly wired, a winding mechanism is installed on the substrate 1. The winding mechanism includes a motor seat 79 provided on the top surface of the substrate 1, a fifth motor 80 installed on the motor seat 79, a winding roller 81 installed on the shaft end of the fifth motor 80, and a line feeding ring 83 installed on the moving seat of a reciprocating screw slide 82. The line of the water quality sensor 10 is wound on the winding roller 81.

[0060] Movement process: the fifth motor 80 drives the winding roller 81 to rotate and wind the sensor line, and the reciprocating screw slide 82 drives the line feeding ring 83 to move reciprocally along the axis of the winding roller 81, so that the line is evenly wound on the winding roller 81, avoiding knotting or stacking.

[0061] Beneficial effect: replacing the traditional manual line arrangement method, preventing the line from being short-circuited or signal interrupted due to long-term use and winding wear, especially suitable for scenarios where the execution arm 8 moves frequently, improving the reliability of long-term operation of the device. The winding motor is only started when the execution arm 8 moves, triggered by a travel switch or a position sensor 26, and is in a dormant state at ordinary times, reducing overall energy consumption.

[0062] As shown in Figures 23-26As shown, as the optimization of embodiment two, considering that impurities in the sewage may adhere to the sampling pipe 61, it is necessary to clean it regularly to ensure the accuracy of the detection data. The top surface of the base 60 is connected with a sealing ring 84, the water inlet 62 of the sealing ring 84 corresponds to the water inlet 62 of the base 60, and the top surface of the sealing ring 84 has a wedge surface; the U-shaped frame 50 is provided with two symmetrically arranged fifth guide rails 85, and the fifth guide rails 85 are slidably connected with a fifth sliding table 86, the sliding direction of the fifth sliding table 86 is parallel to the sliding direction of the fourth sliding table 37, the fifth sliding table 86 is provided with a spray head seat 87, the bottom surface of the spray head seat 87 has a wedge surface, the wedge surface of the spray head seat 87 is matched with the wedge surface of the sealing ring 84, the top surface of the spray head seat 87 is provided with a spray port 88, and the spray port 88 is provided with a nozzle 89; the nozzle 89 is used for cleaning the impurities in the sampling pipe 61; the spray head seat 87 is driven by a second telescopic rod 90, the second telescopic rod 90 can select a cylinder, and the U-shaped frame 50 is provided with a through slot 91 through which the spray head seat 87 passes; the end cover 63 is provided with a one-way valve 92, and the one-way valve 92 is used for discharging the impurity mixed water in the sampling pipe 61.

[0063] The movement process is as follows: the second telescopic rod 90 drives the spray head seat 87 to move along the fifth guide rail 85, the wedge surface of the bottom surface of the spray head seat 87 is matched with the wedge surface of the sealing ring 84 to form a seal. The nozzle 89 sprays high-pressure water flow into the sampling pipe 61 to flush the impurities adhered to the inner wall, and the impurity mixed water is discharged through the one-way valve 92 of the end cover 63.

[0064] The beneficial effects are as follows: without manual disassembly of the sampling pipe 61, cleaning and deslagging are realized through mechanical linkage, the maintenance workload is reduced, and it is especially suitable for high-impurity sewage scenes (such as industrial wastewater) to avoid the influence of impurity adhesion on detection accuracy. The wedge surface cooperation realizes sealing during cleaning, prevents sewage overflow, and at the same time, the one-way valve 92 ensures that the cleaning waste liquid is completely discharged to avoid secondary pollution.

[0065] As shown in the drawings, Figures 27-29As shown in Example 3, unlike Example 2, considering that the above-mentioned impurity mixed water needs to increase the pressure inside the sampling tube 61 before it can be discharged, a slag discharge hole 93 is provided on the end cap 63, and a valve cavity 94 is provided on the end cap 63. A valve core 95 is slidably connected in the valve cavity 94, and the valve core 95 is used to close the slag discharge hole 93. Two spring grooves 96 are provided in the valve cavity 94, and the spring grooves 96 are located on both sides of the valve core 95. A tension spring 97 is installed in one spring groove 96, and a third spring 98 is installed in the other spring groove 96. A pull rod 98 extending to the outside of the end cap 63 is connected to the valve core 95. 9. A traction rope 100 is connected to the pull rod 99. The free end of the traction rope 100 is connected to the nozzle seat 87. When the nozzle seat 87 moves above the sampling tube 61, the traction rope 100 causes the valve core 95 to open, and the impurities mixed with water in the sampling tube 61 can be discharged. A first wheel seat 101 is installed on the end cap 63. A first pulley 102 is rotatably connected to the first wheel seat 101. The traction rope 100 passes over the first pulley 102. A second wheel seat 103 is installed on the nozzle seat 87. A second pulley 104 is rotatably connected to the second wheel seat 103. The traction rope 100 passes over the second pulley 104.

[0066] Movement process: When the nozzle seat 87 moves above the sampling tube 61, the traction rope 100 pulls the valve core 95 through the pulley system, compresses the third spring 98 on one side and stretches the tension spring 97 on the other side, the valve core 95 disengages from the slag discharge hole 93, the pressure in the sampling tube 61 is released, and the impurity mixed water is quickly discharged; after the nozzle seat 87 is reset, the tension spring 97 and the third spring 98 are reset, and the valve core 95 re-closes the slag discharge hole 93.

[0067] Beneficial effects: The mechanical energy of the moving nozzle seat 87 drives the valve core 95, eliminating the need for an additional power source (such as a solenoid valve), reducing energy consumption and cost, and avoiding corrosion problems of electronic components in wastewater environments. The dual-spring structure (tension spring 97 + compression spring) ensures that the valve core 95 is tightly closed when not cleaning, preventing water sample leakage during sampling and improving the reliability of the mechanism.

[0068] like Figure 30 As shown, further addressing the issue of poor data access compatibility in existing outdoor water quality monitoring equipment, a modular design and intelligent control are employed to achieve efficient acquisition and reliable transmission of multi-source sensor data. A multi-protocol compatible telemetry terminal using a replaceable environmental monitoring device is proposed. This terminal's core data processing unit employs an industrial-grade 32-bit MCU, which supports wide voltage input and wide temperature operation. Simultaneously, a built-in multi-protocol parsing engine can adaptively load standard protocols such as Modbus and DL / T645, as well as vendor-specific protocol templates, and combines CRC checksum and sliding filter algorithms to ensure data integrity. Furthermore, the analog / digital sensor interface integrates isolation protection and anti-interference circuitry, enabling adaptation to 4-20mA current loops, RS485 bus, and pulse signal input, supporting daisy-chain connections of up to 247 devices.

[0069] It also includes a wireless communication module using RS485 communication module and Beidou short message double-channel design, RS485 communication module supports DTLS encryption transmission and JWT device authentication, reduces power consumption to 0.89mA through dynamic sleep strategy, and realizes breakpoint resume transmission by using local cache; Beidou channel as a redundant link when cellular network is interrupted, ensures reliable transmission of alarm data. The display module uses ultra-low power LCD, integrates ambient light sensing and password screen function, and displays monitoring parameters and device status in real time.

[0070] It also includes a power system configured with lithium sub-battery and lithium iron phosphate battery dual energy scheme, the former supports standby for more than 3 years without external power supply, the latter combines solar charging with MPPT controller to meet high power consumption demand, supplemented by super capacitor to realize instantaneous power failure protection; intelligent power management dynamically adjusts module power consumption according to power, and configures surge protection circuit to improve outdoor reliability.

[0071] It also includes a terminal shell with IP67 protection level, a modular cavity design to enhance electromagnetic compatibility, support for wall hanging, vertical rod and other installation methods, adapt to -45°~+45° inclined environment, and use waterproof connectors for sensor interfaces to ensure stable outdoor connection. The expansion function integrates an edge computing engine, detects water quality anomalies in real time and provides local early warning, supports OTA remote upgrade and device health diagnosis, and automatically generates maintenance work orders.

[0072] The core innovations include: multi-protocol adaptive analysis technology for plug-and-play devices, dual-energy intelligent switching strategy to extend battery life by more than 30%, and anti-interference design to ensure data error <0.5% in 10V / m electromagnetic environment. The terminal is suitable for sewage plants, urban pipe networks, industrial pollution sources and other scenarios, and has built a full-link reliability system from collection, transmission to power supply, effectively solving the problems of poor compatibility, high power consumption and weak environmental adaptability of existing devices, and has significant industrial application value and patent protection prospects.

[0073] Core function flow: sensor signals are input into the terminal through isolation protection circuit, multi-protocol analysis engine automatically identifies Modbus, DL / T645 and other protocols, performs CRC check and sliding filter on data, and eliminates interference signals. RS485 communication module: normally uses dynamic sleep strategy (power consumption 0.89mA), encrypts transmission data, and supports breakpoint resume transmission; when the cellular network is interrupted, automatically switch to Beidou channel to transmit alarm data first. Lithium sub-battery and lithium iron phosphate battery are dynamically switched according to power, solar charging combined with MPPT controller optimizes energy efficiency, and super capacitor ensures that data is not lost during instantaneous power failure.
