Description

Technical Field

[0001] This invention relates to the field of wastewater treatment control, specifically to a wastewater treatment control device for unmanned wastewater treatment plants. Background Technology

[0002] Unmanned wastewater treatment plants refer to modern wastewater treatment facilities that can achieve fully automated operation of the entire process of wastewater collection, treatment, and discharge without the need for on-site human supervision, by using automated control systems, intelligent monitoring equipment, and remote operation and maintenance technology. The existing utility model patent CN215403151U discloses an electrical control cabinet suitable for integrated sewage treatment equipment, including a cabinet body, a cabinet door, and an industrial control board. The cabinet body is equipped with a booster pump control circuit, an air pump control circuit, a solenoid valve control circuit, a dosing pump control circuit, a float control circuit, and a smart meter. It can be maintained using general-purpose software programming; it can achieve maintenance-free operation via a 4G network, providing integrated remote control, debugging, and updates; the integrated sewage treatment equipment's operating data can be directly reported with low latency; and it can utilize Bluetooth communication technology to view the system status and perform control on-site. This solution achieves efficient sewage treatment operation through remote control. When a large number of control units need to be installed in the electrical control cabinet of a sewage treatment plant, cable trays are often used to install the wiring connectors on the back of the cabinet to make full use of the control within the cabinet. Since the connection stability of the wiring connectors determines whether the unmanned sewage treatment plant can operate safely, when the wiring connectors are placed on the back of the cabinet, the operators cannot directly observe the position of the wiring connectors. Furthermore, as wiring connection points, the wiring connectors generate heat during use. When some wiring connectors overheat, traditional top or side cooling methods cannot effectively cool the wiring connectors, posing a potential threat to the stability of sewage treatment in the unmanned sewage treatment plant.

[0017] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-12 The present invention provides the following technical solutions: Example 1: A wastewater treatment control device for an unmanned wastewater treatment plant includes a wastewater treatment control cabinet 1. An assembly control frame 2 is located on the back of the wastewater treatment control cabinet 1. A movable crossbeam 3 is horizontally mounted within the assembly control frame 2 via a lifting assembly. A horizontally movable seat 8 is horizontally mounted within the movable crossbeam 3 via a screw. The lifting assembly includes two lifting toothed belts 6. Lifting guide slots are provided on both sides of the assembly control frame 2. The movable crossbeam 3 is horizontally inserted into each of the two lifting guide slots. Toothed rollers 4 are rotatably mounted at both the upper and lower ends of each lifting guide slot. The side of the lifting guide slot closest to the toothed rollers 4... Each is equipped with a guide wheel 5. Two toothed rollers 4 are respectively attached to both sides of the lifting toothed belt 6 and are in contact with the two guide wheels 5. The two ends of the lifting toothed belt 6 are respectively connected to the upper and lower ends of the lifting guide groove inserted into the movable crossbeam 3. The two toothed rollers 4 on the same side in the two lifting guide grooves are driven to rotate by a servo motor and a synchronous shaft. In this way, the two lifting toothed belts 6 can make the movable crossbeam 3 rise and fall smoothly under the meshing action of the teeth. The lead screw connected to the horizontal moving seat 8 is also controlled by a servo motor controlled by a PLC, so as to realize the horizontal sliding of the horizontal moving seat 8 within the movable crossbeam 3.

[0019] A temperature monitoring component is installed on the back of the wastewater treatment control cabinet 1 to monitor the temperature of the wiring connectors or electrical components, improving the stability of the control cabinet. The temperature monitoring component is located on one side of the movable horizontal seat 8. It includes an infrared probe module 9, a piston rod 14, a rotating mounting rod 16, and a contact temperature measurement module 19. A cleaning scraper 25 is located on one side of the rotating mounting rod 16, and the side of the cleaning scraper 25 contacts the side of the infrared probe module 9. A water outlet is located on the side of the movable crossbeam 3 near the wiring connector. The horizontal guide groove 7 and the horizontal moving seat 8 are placed horizontally in the horizontal guide groove 7. A piston groove 10 is opened on one side of the horizontal moving seat 8. A piston rod 14 is provided at the center of one side of the infrared probe module 9. The piston rod 14 is movably inserted into the piston groove 10. A return spring 29 is sleeved on the side of the piston rod 14 inserted into the piston groove 10. When high-pressure gas is filled into the piston groove 10, the infrared probe module 9 can move away from the horizontal moving seat 8 by the pushing phase of the piston rod 14. Conversely, it will be reset and attached to the horizontal moving seat 8 under the elastic force of the return spring 29.

[0020] An infrared probe module 9 has a lens at its center on the side away from the horizontal moving base 8. A rotating groove 15 is horizontally opened at the lower end of the infrared probe module 9. A toggle wheel groove 17 is opened on one side of the rotating groove 15. A rotating mounting rod 16 is rotatably inserted into the rotating groove 15. One side of the rotating mounting rod 16 is inserted into the toggle wheel groove 17. Several first actuating blocks 18 are provided on the side of the rotating mounting rod 16 placed in the toggle wheel groove 17. A valve groove is opened at the center of the piston rod 14. A transfer air groove 31 is opened on one side of the valve groove, which is connected to the upper end of one side of the toggle wheel groove 17 and passes through the lower end of one side of the toggle wheel groove 17. The first actuating blocks 18 are located on the path of the transfer air groove 31. When the first actuating blocks 18 are supplied with high-pressure airflow, the high-pressure airflow can actuate the first actuating blocks 18 to realize the rotation control of the rotating mounting rod 16.

[0021] A first pipe joint 12 is provided on one side of the piston groove 10, penetrating the horizontal moving seat 8. A one-way valve 30 is provided in the valve groove of the piston rod 14. An arc-shaped constraint groove 21 is provided on one side of the infrared probe module 9, located in the rotation groove 15. An arc-shaped guide rod 22 is provided in the arc-shaped constraint groove 21. A second actuating block 24 is provided on one side of the rotation mounting rod 16, located in the arc-shaped constraint groove 21. The second actuating block 24 is movably sleeved on the arc-shaped guide rod 22, and an arc-shaped spring 23 is sleeved on one side of the arc-shaped guide rod 22, located on the side of the second actuating block 24. A cleaning scraper 25 is provided on the side of the rotation mounting rod 16 outside the infrared probe module 9. One side of the cleaning scraper 25 is flush with the lens of the infrared probe module 9, and a cleaning strip is provided on the side of the cleaning scraper 25 near the lens. The first pipe joint 12 is positioned correctly. High-pressure airflow generated by the compressor is constantly introduced. When the high-pressure airflow is greater than the supporting force of the return spring 29 and the one-way valve 30, the high-pressure gas can push the infrared probe module 9 to move, or enter the actuation wheel groove 17 from the valve groove and the first actuating block 18, causing the self-rotating mounting rod 16 to rotate. However, since the self-rotating mounting rod 16 is movably connected to the arc-shaped guide rod 22 through the second actuating block 24, the rotation angle of the self-rotating mounting rod 16 is limited. When the self-rotating mounting rod 16 rotates, it can drive the cleaning scraper 25 to wipe and clean the lens of the infrared probe module 9. When the air supply to the first pipe joint 12 is interrupted, the self-rotating mounting rod 16 is pushed back by the arc-shaped guide rod 22 connected to the second actuating block 24, and the cleaning scraper 25 resets and does not block the lens.

[0022] One end of the rotating mounting rod 16 passes through the infrared probe module 9 and has a spring groove. A contact temperature sensing module 19 is movably inserted into the spring groove. A buffer spring 20 is connected to one end of the contact temperature sensing module 19 located in the spring groove, and the contact temperature sensing module 19 extends out of the rotating mounting rod 16. When the infrared probe module 9 moves forward via the piston rod 14, the infrared probe module 9 will get closer and closer to the wiring connector installed on the back of the sewage treatment control cabinet 1. When the probe with the infrared sensing module in the infrared probe module 9 detects that the wiring connector is overheating, it can quickly reach the corresponding location by moving the movable crossbeam 3 and the horizontal moving seat 8. Positioning is achieved, and then the infrared probe module 9 extends. As the infrared probe module 9 moves, the contact temperature measurement module 19 first contacts the wiring connector to achieve contact-type temperature detection of the wiring connector, ensuring accurate overheating information of the wiring connector. Under the elastic buffering effect of the buffer spring 20, the contact temperature measurement module 19 will not cause bump damage to the wiring connector. In addition, the probe of the infrared probe module 9 can assist the operator in safely inspecting the wiring connector on the back of the sewage treatment control cabinet 1 without moving or disassembling the sewage treatment control cabinet 1, thereby improving the stability of sewage treatment in unmanned sewage treatment plants.

[0023] Based on Embodiment 1, a fire-fighting cooling component is provided to provide targeted continuous cooling or emergency fire-fighting treatment for some abnormally overheating wiring connectors. The fire-fighting cooling component is located on one side of the horizontal moving base 8 and includes four airflow ducts 27. An infrared probe module 9 is movably sleeved on the four airflow ducts 27. Guide slots 26 are horizontally opened on all four sides of the infrared probe module 9. An annular air groove 11 is opened on one side of the horizontal moving base 8. One side of each of the four airflow ducts 27 is connected to the annular air groove 11. A second pipe connector 13 is provided through the horizontal moving base 8 on one side of the annular air groove 11. The first pipe connector 12 and the second pipe connector 13 are arranged oppositely. The infrared probe module 9 is guided and sleeved on the four airflow ducts 27 through the four guide slots 26. A rotating groove is opened on the side of the guide slot 26 away from the horizontal moving base 8. A guide elbow 28 is rotatably inserted into each rotating groove. The four guide elbows 28 are respectively connected to the four airflow ducts 27. The four guide bends 28 are connected, with one end pointing to the center of the infrared probe module 9. When overheating or burning of the corresponding wiring connector is detected, the horizontal moving seat 8 and the infrared probe module 9 can be quickly moved to the corresponding wiring connector position. Then, the second pipe joint 13 sends high-pressure airflow, inert gas, or fire extinguishing gas-solid mixture into the annular air groove 11. The airflow duct 27 and guide bends 28 precisely cover the overheated wiring connector for emergency and precise treatment. At this time, the extension of the infrared probe module 9 can bring the airflow outlet closer to the wiring connector, achieving better cooling or flame retardant effects. The position of the second pipe joint 13 can be connected to conventional air compressor equipment or inert gas storage tank through a three-way valve. In conjunction with the probe image and temperature of the infrared probe module 9, it can determine whether to use cooling or emergency fire fighting, so as to realize timely detection and treatment of overheating, reduce energy consumption and reduce later maintenance costs, and improve the safe and stable operation of the unmanned sewage treatment plant.

[0024] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
