Description

Technical Field

[0001] The present application relates to the technical field of submersible detection electrodes, and in particular to an automatic cleaning device for submersible detection electrodes. Background Art

[0002] Detection electrodes refer to working electrodes used to measure various parameter indicators in water bodies or solutions, mainly including pH meters, dissolved oxygen meters, F ion meters and ammonia nitrogen detectors. They are widely used in water treatment, environmental monitoring, aquaculture and other industries. Currently, detection electrodes are mainly divided into fixed and submersible types. Submersible detection electrodes refer to electrodes that are completely immersed in water for detection.

[0003] However, since the submersible detection electrode needs to be immersed in the bottom of the water body to be tested for a long time, the surface of the detection electrode is easily affected by the sediment or water quality in the water, which leads to siltation or scaling on the surface of the electrode, thereby causing errors in the measurement of the electrode and reducing the accuracy of the electrode measurement, which is obviously insufficient. Utility Model Content

[0004] In order to improve the accuracy of electrode measurement, the present application provides an automatic cleaning device for submersible detection electrodes.

[0005] The present application provides a submersible detection electrode automatic cleaning device adopts the following technical solution:

[0006] A submersible detection electrode automatic cleaning device comprises a first protective cover and a second protective cover, wherein the first protective cover and the second protective cover are provided with a detection electrode together, the second protective cover is provided with an air duct, the air duct is sleeved on the outer surface of the second protective cover, the first protective cover is provided with a ventilation component, the ventilation component is used to introduce gas into the air duct, the air duct is provided with a plurality of ventilation holes on the inner circumference of the electrode head of the detection electrode, and the air outlet direction of the ventilation holes is arranged toward the detection electrode.

[0007] By adopting the above technical solution, after the detection electrode sinks to the bottom of the water, gas is regularly introduced into the air duct through the ventilation component, and the gas flows along the air duct to the vent hole. The vent hole compresses the gas into high-pressure gas and sprays it to the electrode head of the detection electrode. The high-pressure gas flushes the silt and dirt attached to the surface of the electrode head out of the surface of the electrode, thereby reducing the impact of silt and dirt on the detection electrode, thereby improving the accuracy of the detection electrode measurement.

[0008] Optionally, the side wall of the air duct close to the second protective cover is made of elastic material, and a protrusion is provided in the air duct. The protrusion is annular and has a semicircular cross-section. When no gas flows into the air duct, the top of the protrusion abuts against the inner wall of the air duct close to the second protective cover.

[0009] By adopting the above technical solution, when the gas continues to flow into the air duct, the gas squeezes the air duct to deform the side wall of the air duct in the direction away from the protrusion, and a gap is generated between the air duct and the protrusion. The gas passes through the gap and is ejected from the vent hole, thereby achieving the cleaning of the detection electrode. When no gas flows into the air duct, the side wall of the air duct gradually returns to its original state and fits tightly against the protrusion. At this time, the air duct is closed by the protrusion, and the liquid cannot pass into the air duct, thereby maintaining the cleanliness of the inside of the air duct and ensuring the cleanliness of the cleaning gas, thereby ensuring the cleaning effect of the gas, and further improving the accuracy of the detection electrode measurement.

[0010] Optionally, the air duct located at the electrode head of the detection electrode is arranged to be inclined, and the inclined direction of the air duct is toward the axial direction of the detection electrode.

[0011] By adopting the above technical solution, the inclined setting of the bottom end of the air duct can ensure that the bottom end of the electrode head of the detection electrode can be cleaned by the high-pressure airflow, thereby increasing the contact range between the gas and the detection electrode, and further improving the cleaning effect of the gas on the detection electrode.

[0012] Optionally, the ventilation component includes an air pump, the air delivery end of the air pump is connected to an air source pipe, and the air outlet of the air source pipe is connected to the air duct.

[0013] By adopting the above technical solution, when the air pump is started, the gas will flow into the air source pipe, and the gas will flow along the air source pipe into the air duct and finally be ejected from the vent. Using the air pump as the air source makes it convenient for workers to control the intermittent start of the air pump through the control system, and the pressure of the ejected gas can also be adjusted by the air pump.

[0014] Optionally, a threaded connector is provided at one end of the second protective sleeve close to the first protective sleeve, and the threaded connector is threadedly connected to the first protective sleeve.

[0015] By adopting the above technical solution, a detachable connection between the first protective cover and the second protective cover is achieved through a threaded connector, which makes it convenient for workers to take out and store the detection electrodes, thereby improving the convenience of workers' operation.

[0016] Optionally, a load block is provided in each of the first protective cover and the second protective cover, and the two load blocks are respectively sleeved on both ends of the detection electrode.

[0017] By adopting the above technical solution, the setting of the weight block improves the overall quality of the detection electrode, ensuring that the detection electrode can completely sink into the liquid. At the same time, workers can replace weight blocks of different weights according to different immersion environments to achieve the purpose of sinking, reducing the impact of water flow on the detection electrode, thereby further improving the measurement accuracy of the detection electrode.

[0018] Optionally, a second sealing gasket is provided at one end of the second protective sleeve close to the electrode head of the detection electrode, and the second sealing gasket is tightly fitted to the outer surface of the detection electrode.

[0019] By adopting the above technical solution, the provision of the waterproof gasket improves the overall sealing of the device, thereby reducing the impact of liquid entering the first protective cover and the second protective cover on the detection electrode.

[0020] Optionally, a plurality of ring buckles are provided on the outer surface of the first protective cover, and the plurality of ring buckles are distributed along the length direction of the first protective cover, and the air source tube is clamped in the ring buckles.

[0021] By adopting the above technical solution, the air source pipe is easily affected by the water flow when it is inside the liquid environment, resulting in bending and the like. At this time, the gas is unable to smoothly enter the air duct. The setting of the ring buckle fixes the air source pipe, thereby improving the stability of the air source pipe in the liquid environment, thereby ensuring the smooth operation of the ventilation assembly.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The present application provides a ventilation component, an air duct and a vent hole, and regularly introduces gas into the air duct through the ventilation component. The gas flows along the air duct and is ejected from the vent hole. The gas washes the sludge and dirt attached to the surface of the electrode head out of the surface of the electrode, thereby reducing the influence of the sludge and dirt on the detection electrode, thereby improving the accuracy of the detection electrode measurement;

[0024] 2. The present application provides a protrusion to seal the air duct, thereby maintaining the cleanliness of the inside of the air duct, thereby ensuring the cleaning effect of the gas and further improving the accuracy of the detection electrode measurement.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses an automatic cleaning device for submersible detection electrodes.

[0031] Reference Figure 1 and Figure 2 A submersible detection electrode automatic cleaning device includes a first protective cover 1 and a second protective cover 2. The first protective cover 1 and the second protective cover 2 are both hollow cylinders. Load blocks 3 are fixedly welded inside the first protective cover 1 and the second protective cover 2. A detection electrode 4 is commonly connected between the two load blocks 3. An end of the detection electrode 4 close to the first protective cover 1 is electrically connected to an electrode signal line 41. One end of the electrode signal line 41 extends out of the first protective cover 1 and is electrically connected to a monitor 42. Workers can read the specific values measured by the detection electrode 4 through the monitor 42. A threaded connector 21 is fixedly connected to the end of the second protective cover 2 close to the first protective cover 1. A threaded groove 11 threadedly matched with the threaded connector 21 is provided on the first protective cover 1.

[0032] Before putting the detection electrode 4 into the liquid environment to be measured, the worker clamps the two ends of the detection electrode 4 between the two weight blocks 3 respectively, then aligns the first protective cover 1 and the second protective cover 2, rotates the second protective cover 2 to make the threaded connector 21 threadedly connected to the thread groove 11 on the first protective cover 1, at this time, the detection electrode 4 is protected inside the first protective cover 1 and the second protective cover 2, and then places the detection electrode 4 in the liquid environment to be measured. Under the weighting effect of the two weight blocks 3, the detection electrode 4 is completely immersed in the liquid and stably immersed in the liquid, which improves the stability during the measurement process.

[0033] Reference Figure 1 and Figure 2The outer surface of the second protective cover 2 is connected to an air duct 5, the cross-section of the air duct 5 is annular and is sleeved on the outer surface of the second protective cover 2, and a ventilation component 6 is arranged on the air duct 5. Specifically, the ventilation component 6 includes an air pump 61, and the air pump 61 is controlled by a control system. The air supply end of the air pump 61 is connected and provided with an air source pipe 62. A plurality of ring buckles 12 are evenly distributed on the outer surface of the first protective cover 1 at equal intervals, and the plurality of ring buckles 12 are fixedly installed on the first protective cover 1. The air source pipe 62 is clamped in the plurality of ring buckles 12 and is connected with the inside of the air duct 5. Under the fixation of the ring buckles 12, the stability of the air source pipe 62 in the liquid environment is improved. The air duct 5 located at the electrode head of the detection electrode 4 is inclined, and the inclination direction of the air duct 5 is toward the axial direction of the detection electrode 4. A plurality of small ventilation holes 51 are opened on the inner circumference of the air duct 5, and the outlet directions of the plurality of ventilation holes 51 are all arranged toward the electrode head of the detection electrode 4.

[0034] After the detection electrode 4 sinks into the liquid to be detected, the control system controls the air pump 61 to start intermittently. When the air pump 61 starts, the gas enters the air duct 5 along the air source pipe 62. Under the guidance of the air duct 5, the gas flows to the vent 51. The vent 51 compresses the gas into high-pressure gas and sprays it to the electrode head of the detection electrode 4. The high-pressure gas flushes the silt and dirt attached to the surface of the electrode head out of the surface of the electrode, thereby reducing the influence of the silt and dirt on the detection electrode 4, thereby improving the measurement accuracy of the detection electrode 4.

[0035] Reference Figure 2 and Figure 3 The side wall of the air duct 5 close to the second protective cover 2 is made of an elastic material. In the present embodiment, the elastic material is EPDM. A protrusion 7 is arranged inside the air duct 5. The protrusion 7 is annularly fixedly connected to the inner side wall of the air duct 5. The cross section of the protrusion 7 is semicircular. When no gas flows into the air duct 5, the top end of the protrusion 7 abuts against the inner side wall of the air duct 5 close to the second protective cover 2.

[0036] When the gas continues to flow into the air duct 5, the gas squeezes the air duct 5 to deform the side wall of the air duct 5 in the direction away from the protrusion 7, and a gap is generated between the air duct 5 and the protrusion 7. The gas passes through the gap and is ejected from the vent 51, thereby cleaning the detection electrode 4. When no gas flows into the air duct 5, the side wall of the air duct 5 gradually returns to its original state and fits tightly against the protrusion 7. At this time, the air duct 5 is closed by the protrusion 7, and the liquid cannot pass into the air duct 5, thereby maintaining the cleanliness of the inside of the air duct 5 and ensuring the cleanliness of the cleaning gas, thereby ensuring the cleaning effect of the gas, and further improving the measurement accuracy of the detection electrode 4.

[0037] Reference Figure 2 and Figure 3In order to improve the sealing performance of the cleaning device, a first sealing gasket 13 is arranged inside the first protective cover 1. The first sealing gasket 13 is sleeved on the outside of the power cord. The inner circumference of the first sealing gasket 13 is in close contact with the power cord, and the outer circumference is in close contact with the surface of the first protective cover 1. A second sealing gasket 22 is installed inside the second protective cover 2. The detection electrode 4 is inserted into the second sealing gasket 22 and the surface of the detection electrode 4 is in close contact with the second sealing gasket 22.

[0038] The provision of the first sealing gasket 13 and the second sealing gasket 22 improves the sealing of the cleaning device as a whole, thereby reducing the influence of liquid entering the first protective cover 1 and the second protective cover 2 on the detection electrode 4 .

[0039] The implementation principle of an automatic cleaning device for a submersible detection electrode in an embodiment of the present application is as follows: after the detection electrode 4 is installed inside the first protective cover 1 and the second protective cover 2, the detection electrode 4 is put into the liquid to be detected. After sinking to the bottom of the water, the air pump 61 is controlled by the control system to start intermittently. When the air pump 61 is started, the gas enters the air duct 5 along the air source pipe 62. Under the guidance of the air duct 5, the gas flows to the vent 51. The vent 51 compresses the gas into high-pressure gas and sprays it to the electrode head of the detection electrode 4. The high-pressure gas washes the silt and dirt attached to the surface of the electrode head out of the surface of the electrode, thereby reducing the influence of the silt and dirt on the detection electrode 4, thereby improving the measurement accuracy of the detection electrode 4.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
