Description

Technical Field

[0001] This utility model relates to the field of wastewater monitoring technology, specifically to an automatic cleaning mechanism for wastewater monitoring sensors. Background Technology

[0002] In wastewater monitoring, various sensors are needed to detect parameters such as pH, ammonia nitrogen, dissolved oxygen, salinity, and conductivity in wastewater. However, during long-term use, the surfaces of existing wastewater monitoring sensors are prone to being covered by impurities and pollutants from the wastewater, affecting the detection accuracy and precision of the sensors. Currently, cleaning the sensors usually requires manual labor. Although some automatic cleaning equipment has achieved cleaning of the detection sensors using spray devices, a single linear lifting spray cannot cover the circumferential surface of the sensor. Especially for multiple sensor arrays, cleaning blind spots are easily formed on the back and sides. Automatic cleaning methods are difficult to perform comprehensive cleaning of multiple sensors from multiple angles, resulting in poor cleaning effects.

[0003] Therefore, an automatic cleaning mechanism for wastewater monitoring sensors is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic cleaning mechanism for wastewater monitoring sensors. A lifting assembly drives a spray bar to move up and down, which, in conjunction with multiple nozzles on both sides of the spray bar, performs initial vertical spray cleaning of the sensor and protective net, covering the front of the sensor and the surface of the protective net. Simultaneously, a rotating assembly drives the sensor to rotate around a bearing, sequentially exposing the sensor's circumferential surface to the spray range. This effectively solves the problem that a single linear lifting spray cannot cover the back and sides of the sensor, avoiding the formation of cleaning blind spots and addressing the issues raised in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: it includes multiple detection sensors and a spray rod. The multiple detection sensors are rotatably connected to the base plate via bearings. An inner shell is fixedly connected to the upper surface of the base plate. A rotating component is provided inside the inner shell. A lifting component is provided on the upper surface of the inner shell. The spray rod is connected to an external water source via a hose. Multiple nozzles are provided on both sides of the spray rod. An outer shell is provided outside the lifting component. A protective net is fixedly connected to the bottom of the outer shell.

[0006] Preferably, the rotating assembly includes a double-headed electric actuator, a push rod, and a connecting rod. One end of the connecting rod is fixedly connected to a detection sensor, and the other end of the connecting rod has an elongated hole. Multiple shafts are fixedly connected to the side of the push rod near the connecting rod, and the shafts are inserted into the elongated hole. Both ends of the double-headed electric actuator are connected to the push rod via extension plates.

[0007] Preferably, the lifting assembly includes a winding belt, a spool, a connecting rod, and a dual-head motor. One end of the winding belt is connected to the spool, and the other end of the winding belt is connected to the spray bar. The connecting rod is used to connect two spools, and the dual-head motor is used to drive the connecting rod.

[0008] Preferably, a first helical gear is fixedly connected to one end of the connecting rod near the dual-head motor, and a second helical gear is connected to each of the two output shafts of the dual-head motor, with the first and second helical gears meshing.

[0009] Preferably, the outer casing is fixedly connected with a scraper and a guide rod. The scraper is located on both sides of the winding belt and is used to scrape away debris from both sides of the winding belt. The guide rod contacts the inner side of the winding belt and is used to guide the winding belt.

[0010] Preferably, a cable is connected to the top of the detection sensor, and multiple cables are combined into a main cable.

[0011] Compared with the prior art, this utility model provides an automatic cleaning mechanism for sewage monitoring sensors, which has the following beneficial effects:

[0012] 1. The lifting assembly drives the spray bar to move up and down, and with the multiple nozzles on both sides of the spray bar, it can perform preliminary vertical spray cleaning on the detection sensor and protective net, covering the front of the sensor and the surface of the protective net. At the same time, the rotating assembly can drive the detection sensor to rotate around the bearing, so that the circumferential surface of the sensor is exposed to the spray range in sequence. This effectively solves the problem that a single linear lifting spray cannot cover the back and sides of the sensor, and avoids the formation of cleaning blind spots. Attached Figure Description

[0019] 42342 The technical solutions of the present utility model will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Example:

[0021] Please see Figure 1 - Figure 4 This embodiment of an automatic cleaning mechanism for a wastewater monitoring sensor includes multiple detection sensors 2, a spray bar 3, a rotating assembly 8, and a lifting assembly 9. The multiple detection sensors 2 are rotatably connected to a base plate 6 via bearings 7 and can rotate around the axis of the bearings 7. An inner shell 4 is fixedly connected to the upper surface of the base plate 6. The rotating assembly 8 is used to drive the detection sensors 2 to rotate. The lifting assembly 9 on the upper surface of the inner shell 4 is used to drive the spray bar 3 to rise and fall. The spray bar 3 is connected to an external water source via a hose 12. Multiple nozzles on both sides spray water onto the detection sensors 2 and the protective net 1 during the rising and falling process. The outer shell 5 encloses the lifting assembly 9, and the protective net 1 at the bottom can block larger impurities in the wastewater and protect the internal structure.

[0022] Rotating assembly 8 includes a double-headed electric actuator 801, a push rod 802, and a connecting rod 803. One end of the connecting rod 803 is fixedly connected to the detection sensor 2, and the other end has an elongated hole 13. The first shaft 14 of the push rod 802 is inserted into the elongated hole 13. When the double-headed electric actuator 801 drives the push rod 802 to move through the extension plate, the first shaft 14 slides in the elongated hole 13, pushing the connecting rod 803 to rotate around the axis of the detection sensor 2, thereby driving the detection sensor 2 to rotate. Lifting assembly 9 includes a winding belt 901, a winding shaft 902, a connecting rod 903, and a double-headed motor 904. One end of the winding tape 901 is connected to the roller 902, and the other end is connected to the spray bar 3. The dual-head motor 904 drives the connecting rod 903 to rotate through the meshing of the first helical gear 15 and the second helical gear 16, which drives the rollers 902 on both sides to synchronously wind and unwind the winding tape 901, thereby realizing the lifting and lowering of the spray bar 3. The scraper 10 and guide rod 11 fixedly connected to the outer shell 5 scrape away the debris on both sides of the winding tape 901 and guide the winding tape 901 to ensure the stability of the lifting and lowering process. The cable 17 at the top of the detection sensor 2 is connected to the main cable 18 for easy signal transmission.

[0023] The working principle of the above embodiment is as follows: the lifting component 9 drives the spray bar 3 to move up and down, and with the help of multiple nozzles on both sides of the spray bar 3, the detection sensor 2 and the protective net 1 are initially sprayed and cleaned in the up and down direction, covering the front of the detection sensor 2 and the surface of the protective net 1. At the same time, the rotating component 8 can drive the detection sensor 2 to rotate around the bearing 7, so that the circumferential surface of the detection sensor 2 is exposed to the spray range in sequence, avoiding cleaning blind spots.

[0024] During use, an external water source supplies water to the spray bar 3 through the hose 12. The dual-head motor 904 drives the connecting rod 903 to rotate, which in turn drives the reel 902 to wind and unwind the belt 901, causing the spray bar 3 to rise and fall. The nozzles on both sides spray the detection sensor 2 and the protective net 1 from top to bottom for cleaning. After cleaning, the dual-head electric push rod 801 pushes the push rod 802 to move, which drives the detection sensor 2 to rotate around the bearing 7 through the connecting rod 803, so that the uncleaned circumferential surface is turned into the spray range, achieving multi-angle cleaning. First, the dual-head motor 904 is started to lower the spray bar 3 to the bottom, and then it is raised to perform preliminary cleaning. Then, the dual-head electric push rod 801 is started to rotate the detection sensor 2, and the spray bar 3 is raised and lowered again to complete the full cleaning. The scraper 10 and the guide rod 11 ensure that the belt 901 is clean and accurately guided, ensuring the long-term stable operation of the mechanism.
