Description

Technical Field

[0001] The invention relates to the technical field of water quality monitoring equipment, and in particular to a self-cleaning water quality environment monitoring device. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality conditions to meet the needs of water area emergency and management. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage, etc. The main monitoring items are temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand, toxic metals, etc., so water quality environment monitoring devices will be used.

[0003] Existing water quality environment monitoring devices have many defects in monitoring and detection. First, when monitoring water quality, it is necessary to sample water layers of different depths, but the current equipment can only collect water samples of one depth each time, and it is necessary to collect them in multiple steps, which has low work efficiency; second, the enrichment of nutrients in the water quality environment will lead to the formation of large particles of impurities and bubble aggregation. These large particles of impurities and bubbles will interfere with the accuracy of the detection data of specific types of sensors during detection, such as photoelectric technology sensors, and will also affect the uniformity of water samples; third, during continuous detection, the outer surface of the sensor detection probe is easily adsorbed with stains, which affects the accuracy of water quality detection. There are also filamentous impurities adhering to the detection probe, which affects the monitoring results and is not easy to clean. The existing practice is to remove the sensor and perform manual cleaning, but this is time-consuming and labor-intensive, and the degree of automation is low.

The crushing roller uses several groups of long knives to contact the large particles of impurities and bubbles in front of the net in the movement path, and crushes and eliminates them, so that they can pass through the intercepting net and finally enter the detection pool smoothly, ensuring the uniformity of the water sample and avoiding interference with the detection accuracy of the sensor.

[0032] Let the air pump work and inflate one group of corrugated telescopic tubes. The gas enters into the close-fitting airbag through the intake pipe, causing the close-fitting airbag to expand inward. The cleaning sponge is used to fully contact the detection probe of the sensor and fit the annular wall. Then the second servo motor is started to drive the cam on the camshaft to make a circular motion. After a series of transmissions, the connecting arm is driven to move downward, so that the annular cleaning seat moves downward outside the detection probe. The cleaning sponge is used to wipe the stains and filamentous impurities outside the detection probe while moving. When the protruding part of the cam leaves the contact wheel, the reset elastic force of the reset spring causes the intermediate platform and the guide column to return to their positions. The reciprocating motion of the cleaning sponge is used to fully clean the detection probe, thereby improving the cleaning effect and saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Furthermore, sampling brackets 20 are vertically and equidistantly installed at the lower end of the linear motion plate 10, and a through hole for the sampling brackets 20 to pass through up and down is opened at the bottom of the support seat 2. Adjacent sampling brackets 20 are connected and fixed by connecting rods 21 (the length of the connecting rods 21 needs to be adaptively designed according to the sampling depth). A perforated bottom plate 22 is provided at the bottom of the sampling bracket 20, and the perforated bottom plate 22 is used to reduce water resistance. Each group of sampling brackets 20 is provided with a sampler 7 and a flip structure 8, such as Figure 4 and Figure 5 shown.

[0054] Specifically, the sampler 7 includes a sampling bottle 71, a roller 72, a damping bearing 73, a bottle mouth 74 and a control valve 75. Figure 6 shown.

[0055] In this embodiment, rollers 72 are symmetrically fixed on both sides of the sampling bottle 71. Each group of rollers 72 is fixed by a damping bearing 73 and the inner side of the sampling bracket 20. The damping bearing 73 has a damping force to prevent the sampling bottle 71 from rotating. The upper end of the sampling bottle 71 is provided with a bottle mouth 74, and a control valve 75 is installed in the bottle mouth 74.

[0056] Specifically, the flip structure 8 includes a hydraulic cylinder 81, a telescopic rod 82 and a hinge joint 83. Figure 7 shown.

[0060] Furthermore, a drainage channel 30 is provided at the middle of the bottom of the working tank 5. The drainage channel 30 is slightly inclined to the left. The sampling bottle 71 is turned over in the sampling bracket 20 (the sampling bottle 71 is turned over so that the bottle mouth 74 is closer to the drainage channel 30), and the water sample is poured into the drainage channel 30. Baffles 39 are symmetrically provided on both sides of the drainage channel 30. Figure 8 shown.

[0061] A grid frame 31 is arranged above the drainage channel 30, and the grid frame 31 is fixed between two sets of baffles 39. An interception net 32 ​​acting on the drainage channel 30 is installed in the grid frame 31. Figure 8 shown.

[0062] Furthermore, a breaker 9 is provided on the outside of the interception net 32. Figure 8 shown.

[0063] Specifically, the crusher 9 includes a crushing roller 91, a long knife 92, a shaft 93, a second bearing seat 94, a second large gear 95, a second small gear 96 and a constant speed motor 97. Fig. 9 shown.

[0064] In this embodiment, long knives 92 are evenly distributed on the roller surface of the crushing roller 91, and the long knives 92 crush the impurities and bubbles in the water sample in the drainage channel 30 (the movement path of the long knives 92 will not touch the interception net 32). Shafts 93 are welded at both ends of the crushing roller 91, and a second bearing seat 94 fixed to the baffle 39 is sleeved on the shaft 93. One group of shafts 93 is sleeved with a second large gear 95, and the upper end of the second large gear 95 is meshed with a second small gear 96. The second small gear 96 is sleeved on the output shaft of the uniform speed motor 97, and the uniform speed motor 97 is horizontally fixed on the groove wall of the working groove 5.

[0065] Furthermore, a detection pool 37 is provided at the bottom of the working tank 5 and is located on the left side of the drainage channel 30. A drainage valve is installed at the bottom of the detection pool 37 (a cleaning nozzle is also installed in the detection pool 37 to clean the pool wall in time). A sensor support 33 is mounted directly above the detection pool 37. Both ends of the sensor support 33 are fixed to the inner wall of the working tank 5. Figure 8 shown.

[0066] Specifically, a plurality of sensor groups 34 are mounted on the sensor support 33, and the plurality of sensor groups 34 include electrochemical sensors, optical sensors, biosensors, pH sensors, conductivity sensors, dissolved oxygen sensors, turbidity sensors, and ammonia nitrogen sensors (one or more of them are selected according to actual needs). The lower end of the sensor 34 passes through the sensor support 33 and extends into the detection tank 37, where a detection probe 38 is provided. Each sensor group 34 is connected to a display 36 via respective wires 35, and the display 36 is located on the left side of the upper end surface of the detection box 1, as shown in FIG. Figure 1 , Figure 8 and Fig.10 shown.

[0067] Furthermore, a support leg is provided between the motor drive seat 63 and the support seat 2 to play a supporting role, such as Figure 2 shown.

[0068] Furthermore, the monitoring device is suitable for waters with a depth of 2-8m and is installed above the monitored waters.

[0069] When the present embodiment is in use, the first servo motor 17 is first started to drive the first small gear 16 to rotate, and the first large gear 15 is rotated through meshing, and the rack wheel 18 is caused to make a circular motion. When the rack wheel 18 moves, it drives the linear motion plate 10 with the rack 12 to move downward, so that the several groups of sampling brackets 20 below the linear motion plate 10 are fully extended into the water quality detection river, so that each group of samplers 7 is distributed in water layers of different depths, and then the control valve 75 on each group of samplers 7 is opened at the same time, so that water samples of different depths enter their respective sampling bottles 71, and the control valve 75 is closed in time to reverse the first servo motor 17. After a series of transmissions, the linear motion plate 10 is caused to move upward, and the sampling bracket 20 is driven to return upward.

[0070] When the sampler 7 at the highest position first enters the working groove 5, the movement is paused, the hydraulic cylinder 81 is started, and the telescopic rod 82 is extended upward, causing the crank 84 to rotate around the hinge joint 83, and through the interaction of the crank 84 and the movable column 87 (the movable column 87 moves linearly in the waist-shaped groove 85), the sampling bottle 71 is turned counterclockwise around the two sets of damping bearings 73, so that the bottle mouth 74 is tilted downward. At this time, the control valve 75 is opened to tilt the water sample in the sampling bottle 71 and pour it out, directly falling into the right end of the drainage channel 30, and flowing to the left end and entering the detection pool 37. At this time, the telescopic rod 82 is retracted downward to make the sampling bottle 71 turn back to its original position.

[0071] When the water sample flowing in the drainage channel 30 passes through the interception net 32, large particles of impurities and bubbles are intercepted. At this time, the uniform speed motor 97 on the crusher 9 is started to drive the second small gear 96 to rotate, and drives the second large gear 95 to rotate through engagement, causing the coaxial crushing roller 91 to make a circular motion. The crushing roller 91 uses several groups of long knives 92 to contact the large particles of impurities and bubbles in front of the net in the movement path, and crushes and eliminates the two, so that they can pass through the interception net 32 ​​and finally enter the detection pool 37 smoothly.

[0072] Then, several groups of sensors 34 are put into operation, and the detection probe 38 is extended into the detection pool 37 to measure the various index data of the water sample, and then the values ​​are uniformly displayed on the display 36. Then, the drain valve at the bottom of the detection pool 37 is opened to release the water sample, and then the pool wall is cleaned with a cleaning nozzle. Then, the linear motion plate 10 is driven to continue to move upward one grid, and the second group of samplers 7 repeats the above operation for detection, and the cycle is repeated. Example 2

[0073] On the basis of the first embodiment, during continuous detection, the outer surface of the detection probe 38 is easily adsorbed with stains, which affects the accuracy of water quality detection. In addition, filamentous impurities adhere to the detection probe 38, which affects the monitoring results and is not easy to clean. The existing method is to remove the sensor 34 and perform manual cleaning, but this is time-consuming and labor-intensive, and the degree of automation is low. In order to solve the above technical problems, we have the following design, such as Figure 10-13 shown.

[0074] Specifically, a cam 40 is movably provided inside the sensor support 33 and on one side of each group of sensors 34. Fig.11 shown.

[0075] The cam 40 is sleeved on the camshaft 41, one end of the camshaft 41 is connected to the second servo motor 42 through a coupling, the second servo motor 42 is in a horizontal fixed state, and the other end of the camshaft 41 is fixed by the third bearing seat 43 and the inner wall of the sensor support 33. Fig.11 shown.

[0076] Further, an intermediate platform 44 is provided directly below each set of cams 40, and a wheel groove 45 is provided extending upward from the interior of the intermediate platform 44. A contact wheel 46 is rotatably provided in the wheel groove 45, and a portion of the contact wheel 46 extends out of the wheel groove 45. The contact wheel 46 and the wheel surface of the cam 40 interact with each other, as shown in FIG. Fig.12 shown.

[0077] Furthermore, a guide column 47 is fixedly connected to the lower end of the intermediate platform 44. The guide column 47 passes through a positioning plate 48. A column hole is provided on the positioning plate 48 for the guide column 47 to move, which plays a limiting and guiding role. The positioning plate 48 is riveted to the inside of the sensor support 33. A return spring 49 is fixedly arranged between the positioning plate 48 and the intermediate platform 44 and is sleeved on the outside of the guide column 47. Fig.12 shown.

[0078] Furthermore, a connecting arm 50 is welded to the lower end of the guide column 47, and a limiting opening 64 is provided at the bottom of the sensor support 33 for the connecting arm 50 to pass through, which plays a role of limiting storage, and an annular cleaning seat 51 is riveted to the lower end of the connecting arm 50, such as Fig.10 and Fig.12 shown.

[0079] In this embodiment, each group of annular cleaning seats 51 is respectively sleeved on the outer side of the detection probe 38, and a limited airbag sleeve 52 is arranged inside the annular cleaning seat 51. A close-fitting airbag 53 is glued to the inner side of the limited airbag sleeve 52. The close-fitting airbag 53 itself has the ability to reset after deformation. The close-fitting airbag 53 partially extends out of the inner side of the annular cleaning seat 51. A cleaning sponge 54 is arranged on the inner side of the close-fitting airbag 53. The cleaning sponge 54 is compressible and can be flexibly disassembled and replaced. The cleaning sponge 54 acts on the outer side of the detection probe 38. Fig.10 and Fig.13 shown.

[0080] In this embodiment, an air inlet pipe 57 is provided close to the outside of the airbag 53, and a one-way valve is installed on the air inlet pipe 57. The air inlet pipe 57 passes through the annular cleaning seat 51 and is connected to a bellows telescopic pipe 55. The bellows telescopic pipe 55 can be telescopically adapted with the up and down movement of the annular cleaning seat 51. A pressure relief valve 56 is installed close to the upper end surface of the airbag 53 for releasing the gas in the airbag 53. Fig.10 and Fig.13 shown.

[0081] Furthermore, an air pump is installed on the upper end surface of the sensor holder 33, and a porous joint is installed at the inflation port of the air pump. Multiple groups of solenoid valves are installed in the porous joint to respectively control the air supply needs of different airbags 53. Each group of bellows expansion tubes 55 extends upward and is connected to the porous joint.

[0082] When the present embodiment is in use, the air pump is operated, and one of the solenoid valves is opened to inflate one of the bellows expansion tubes 55. The gas enters the close-fitting airbag 53 through the air inlet pipe 57, so that the close-fitting airbag 53 expands toward the inner center, expanding the space in the inner area. The cleaning sponge 54 and the detection probe 38 of the sensor group 34 are fully in contact with each other, and the annular wall is fitted. Then, the second servo motor 42 is started to drive the cam 40 on the camshaft 41 to make a circular motion. When the protruding part of the cam 40 contacts the contact wheel 46 during the movement, the two generate pressure, causing the middle The platform 44 and the guide column 47 move downward (the guide column 47 compresses the return spring 49 during the downward movement), driving the connecting arm 50 to move downward, so that the annular cleaning seat 51 moves downward outside the detection probe 38, and the cleaning sponge 54 is used to wipe the stains and filamentous impurities outside the detection probe 38 while moving. When the protruding part of the cam 40 leaves the contact wheel 46, the return elastic force of the return spring 49 causes the intermediate platform 44 and the guide column 47 to return to their original positions, so that the annular cleaning seat 51 moves upward outside the detection probe 38, and the wiping movement of the cleaning sponge 54 forms a reciprocating state.
