Description

Technical Field

[0001] This utility model relates to the technical field of probe cleaning auxiliary devices, and in particular to a dissolved oxygen sensor probe cleaning device. Background Technology

[0002] Dissolved oxygen sensor probes, as key devices for measuring dissolved oxygen concentration in water bodies, play a vital role in environmental monitoring, aquaculture, and other fields. They provide crucial data on oxygen levels in water bodies and can be widely applied to various aquatic environments, including natural water bodies, aquariums, and ponds. By continuously monitoring dissolved oxygen concentration, researchers can assess the health of aquatic ecosystems, determine the degree of water pollution, and ascertain whether a water body possesses suitable conditions for biological survival.

[0003] In practical applications, dissolved oxygen sensor probes need to be immersed in water samples for a long time for monitoring. Since natural or aquaculture water bodies often contain a large number of impurities, such as suspended particles, algae, and microorganisms, these impurities are very easy to adhere to the surface of the sensor probe. Over time, the accumulation of impurities on the probe will seriously affect its reaction efficiency with oxygen in the water, thus leading to a decrease in monitoring accuracy and an inability to accurately reflect the actual dissolved oxygen content in the water.

[0004] Currently, the main method for restoring the performance of dissolved oxygen sensor probes contaminated with dirt and grime is manual cleaning. However, manual cleaning is not only time-consuming and labor-intensive, but improper operation during the cleaning process can also damage the probe, affecting its subsequent service life and measurement accuracy. Therefore, developing a device that can effectively and conveniently clean dissolved oxygen sensor probes is of significant practical importance. Utility Model Content

[0005] To address the inconvenience of existing manual cleaning methods, this invention provides a dissolved oxygen sensor probe cleaning device.

[0006] The technical solution of this utility model is achieved through the following scheme: a dissolved oxygen sensor probe cleaning device, including a dissolved oxygen sensor probe and a cleaning box, wherein the top surface of the cleaning box is provided with a probe lowering device, the dissolved oxygen sensor probe is detachably installed in the probe lowering device, and the inner cavity of the cleaning box is provided with a cleaning system, a cleaning system and a draining system from top to bottom, the top surface of the cleaning box is provided with wiping components arranged opposite to each other, and the top surface of the cleaning box has a lowering hole, which is located between the wiping components.

[0007] Preferably, the cleaning system includes a water tank, a first pump body, and several water mist nozzles. The water tank, the first pump body, and the several water mist nozzles are all connected by pipelines. The water tank and the first pump body are both installed on the outer surface of the cleaning tank.

[0008] The pipeline includes an external pipeline and an internal pipeline. The water tank is connected to the first pump body through the external pipeline. The first pump body is connected to the internal pipeline. A plurality of water mist nozzles are installed in a circular array on the internal pipeline. The internal pipeline is installed on the top of the inner cavity of the cleaning tank through a hanging ring.

[0009] Preferably, the cleaning system includes several cleaning rollers, several second motors, an electric slide rail, and a limiting wheel. One end of the cleaning roller is connected to the drive end of the second motor, and the other end of the cleaning roller is fitted with a limiting wheel via a bearing. The several second motors are slidably mounted in the electric slide rail via sliding mounting seats, and the electric slide rail is located on one side of the cleaning tank.

[0010] Preferably, the other side of the cleaning box has a limiting groove, the limiting wheel is slidably installed in the limiting groove, the cleaning box is provided with oppositely arranged extrusion blades, the cleaning roller is located between the extrusion blades, and the electric slide rail is provided with a partition.

[0011] Preferably, the drainage system includes a stirring fan, a third motor, a conveying roller, and a second pump body. The stirring fan is rotatably installed at the bottom of the inner cavity of the cleaning tank. A drainage trough is opened at the bottom of the inner cavity of the cleaning tank. The conveying roller is rotatably installed in the drainage trough by the third motor. The drainage trough is connected to the outlet pipe. The second pump body is installed on the outlet pipe. The drainage trough is located below the stirring fan.

[0012] Preferably, the wiping component includes a second linear actuator, a mounting component, and a sponge block. The mounting component is fixedly mounted on the telescopic end of the second linear actuator, and the sponge block is detachably mounted on the mounting component.

[0013] Preferably, the probe lowering device, cleaning system, wiping system, and drainage system are all communicatively connected to the control panel.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. This utility model uses a probe lowering device to lower the probe into the cleaning tank. The cleaning system performs a preliminary spray rinse on the probe surface, effectively washing away most of the impurities attached to the probe. The cleaning system further performs a deep cleaning of the probe to ensure that any remaining stubborn impurities are completely removed. The drainage system discharges the wastewater and impurities generated during the cleaning process, and when the probe is pulled out, the wiping device absorbs the moisture on the probe surface, restoring the probe's normal ability to react with oxygen in the water.

[0016] 2. Several water mist nozzles are installed in a circular array on the internal pipeline, so that the water mist evenly covers the surface of the object to be cleaned in the cleaning chamber, effectively improving the comprehensiveness and uniformity of cleaning, avoiding cleaning dead corners, and ensuring that all parts of the object are thoroughly cleaned.

[0017] 3. Driven by the second motor, the cleaning roller can rotate stably to effectively clean the probe surface. At the same time, with the help of the electric slide rail, the position of the cleaning roller can be flexibly adjusted according to the size and position of the object to be cleaned, improving the targeting and efficiency of the cleaning. The limit wheel provides precise guidance and limit for the movement of the cleaning roller, ensuring that the cleaning roller remains stable during the movement and will not deviate or shake. With the help of the squeezing knife, the residual moisture and stains inside the roller body after cleaning the probe are completely removed.

[0018] 4. The liquid at the bottom of the cleaning tank is stirred by the rotating agitator to prevent impurities from settling and accumulating at the bottom of the tank, ensuring that the liquid can flow smoothly to the drain tank. The rotation of the conveyor roller assists in conveying the liquid to the outlet pipe, further improving the drainage efficiency and preventing the drain tank from getting clogged.

[0019] 5. Utilize the soft and absorbent properties of the sponge to wipe and clean the moisture from the surface of the target object. Attached Figure Description

[0026] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] A dissolved oxygen sensor probe cleaning device, such as Figures 1-5 As shown, the system includes a dissolved oxygen sensor probe and a cleaning tank 1. The top surface of the cleaning tank 1 is equipped with a probe lowering device 2, allowing the dissolved oxygen sensor probe to be detachably installed within the device. The inner cavity of the cleaning tank 1 contains, from top to bottom, a cleaning system 3, a rinsing system 4, and a drainage system 6. The top surface of the cleaning tank 1 has oppositely positioned wiping components 5. A lowering hole is located in the center of the cleaning tank 1, between the wiping components 5. The wiping components 5 are positioned opposite each other with the lowering hole's center point, wiping and drying the wetted and cleaned dissolved oxygen sensor probe. The probe lowering device 2, cleaning system 3, cleaning system 4, wiping component 5, and drainage system 6 are all communicatively connected to the control panel 7. The cleaning tank 1, with the control panel 7 installed on one side, also has an observation window, allowing operators to observe the cleaning process in real time and adjust the position and parameters of each component to ensure optimal cleaning results. The bottom of the drainage system 6, installed inside the cleaning tank 1, has a drainage slope to better concentrate the cleaning liquid at the bottom of the cleaning tank 1. The cleaning tank 1 is divided into three areas: upper layer: probe loading and wiping area; middle layer: cleaning / cleaning execution area; lower layer: waste liquid collection and discharge area.

[0029] The cleaning system 3 is responsible for the initial cleaning, removing most of the dirt from the probe surface; the cleaning system 4 performs further fine cleaning to ensure that the probe surface is clean and free of residue; the drainage system 6 is responsible for draining the used cleaning solution to maintain a clean cleaning environment.

[0030] like Figure 1 and Figure 2 As shown, the probe lowering device 2 includes a first linear actuator 21, a first motor 22, and a probe mounting component 23. The telescopic end of the first linear actuator 21 is fixedly mounted with a mounting plate. The first motor 22 is mounted on the upper surface of the mounting plate. The driving end of the first motor 22 passes through the mounting plate and is connected to the probe mounting component 23. The probe mounting component 23 is fixed by tightening bolts to secure the dissolved oxygen sensor probe. The probe mounting component 23 has an internal hole, and bolts are screwed in to abut against the probe and fix it. The telescopic end of the first linear actuator 21 drives the dissolved oxygen sensor probe to descend, and the first motor 22 drives the rotation to increase the cleaning effect.

[0031] Both the first linear actuator 21 and the second linear actuator 51 are servo electric cylinders, which precisely control the lifting position.

[0032] The cleaning system 3 includes a water tank 31, a first pump body 32, and several water mist nozzles 33. The water tank 31, the first pump body 32, and the several water mist nozzles 33 are all connected by pipelines. The water tank 31 and the first pump body 32 are both installed on the outer surface of the cleaning tank 1. The water tank 31 is mounted on a protruding support plate of the cleaning tank 1. The pipelines include external pipelines and internal pipelines. The water tank 31 is connected to the first pump body 32 via an external pipeline, and the first pump body 32 is connected to the internal pipeline. The several water mist nozzles 33 are installed in a circular array on the internal pipeline, which is installed inside the cleaning tank 1 via hanging rings. At the top of the chamber, the internal pipes are circular and connected to the external pipes, and are on the same axis as the lowering hole. The water mist nozzles 33 installed on them are all tilted downwards towards the central axis, forming a cone-shaped spray area for comprehensive spraying. This ensures that the dissolved oxygen sensor probe is fully covered during the lowering process, effectively removing surface dirt and residues and avoiding incomplete cleaning. The number of lifting rings is preferably four, arranged in a circular array at 120-degree intervals. This multi-point fixing disperses the force on the internal pipes, preventing pipe loosening due to vibration or long-term use, and ensuring the long-term stable operation of the spray system.

[0033] The cleaning system 4 includes several cleaning rollers 41, several second motors 42, an electric slide rail 43, and a limiting wheel 44. One end of the cleaning roller 41 is connected to the drive end of the second motor 42, and the other end of the cleaning roller 41 is bearing-mounted with a limiting wheel 44. Several second motors 42 are slidably mounted in the electric slide rail 43 via sliding mounting seats. The electric slide rail 43 is located on one side of the cleaning tank 1. A sliding mounting seat is slidably mounted in the electric slide rail 43, and the second motors 42 are mounted on the sliding mounting seat. The cleaning rollers 41 are preferably cleaning cotton rollers. Due to the spraying of the cleaning system 3, the cleaning rollers 41 will also be wetted. The cleaning rollers 41 are driven by the electric slide rail 43 to approach or separate, and wipe and clean the lowered dissolved oxygen sensor probe.

[0034] A limiting groove is opened on the other side of the cleaning box 1. The limiting wheel 44 is slidably installed in the limiting groove to limit the movement direction of the cleaning roller 41 and ensure the stability of the cleaning roller 41 during movement. The cleaning box 1 is provided with oppositely arranged extrusion blades 9. The cleaning roller 41 is located between the extrusion blades 9. Preferably, there are two extrusion blades 9, one on the left and one on the right. The number of the second motor 42 and the cleaning roller 41 is preferably two. The electric slide rail 43 is provided with a partition 8, which isolates the entire system into left and right sides. The two sides are separated by a soft partition to avoid collision and damage. Both extrusion blades 9 can abut against the cleaning roller 41 on the same side. After the cleaning roller 41 completes a cleaning task, the second motor 42 is controlled to rotate in the opposite direction briefly, cooperating with the extrusion blades 9 to squeeze in the opposite direction and completely remove the residual water and dirt inside the roller.

[0035] The drainage system 6 includes a stirring fan 61, a third motor 62, a conveying roller 63, and a second pump body 64. The stirring fan 61 is rotatably mounted at the bottom of the inner cavity of the cleaning tank 1. A drainage trough is opened at the bottom of the inner cavity of the cleaning tank 1. The conveying roller 63 is rotatably mounted in the drainage trough via the third motor 62. The drainage trough is connected to an outlet pipe, and the second pump body 64 is installed on the outlet pipe. The drainage trough is located below the stirring fan 61. The stirring fan 61 is driven by a fourth motor (not shown in the figure), which is embedded in the bottom of the cleaning tank 1. The drainage trough is opened in the inner cavity of the cleaning tank 1. On one side of the bottom of the inner cavity of the washing tank 1, there is a liquid guide slope. The conveying roller 63 is preferably a spiral roller. The four liquid guide slopes on the bottom of the inner cavity of the washing tank 1 form a frustum shape. Under the action of gravity, they will naturally slide down to the central area, so that the stirring fan 61 can collect sewage impurities more efficiently. The stirring fan 61 sweeps them into the spiral roller. The spiral roller rotates layer by layer to transport the sewage impurities out. In conjunction with the second pump body 64, the drainage and cleaning are completed. The spiral rotation of the conveying roller 63 and the rotation of the stirring fan 61 effectively prevent impurities from settling and solidifying.

[0036] The wiping component 5 includes a second linear actuator 51, a mounting component, and a sponge block 52. The mounting component is fixedly mounted on the telescopic end of the second linear actuator 51, and the sponge block 52 is detachably mounted on the mounting component. The sponge block 52 wipes and cleans the dissolved oxygen sensor probe, absorbing moisture from its surface. When the second linear actuator 51 is activated, its telescopic end extends or retracts, driving the mounting component and the sponge block 52 mounted on the mounting component to move in a linear motion. During the movement, the sponge block 52 contacts the surface of the target object, using its soft and absorbent properties to wipe and clean the moisture from the surface of the target object. The sponge block 52 is connected to the mounting component by a rigid clip (similar to the replacement of the sponge mop head), allowing for quick replacement when the sponge block 52 is worn or needs to be replaced with a different size sponge block 52. It also facilitates the cleaning and maintenance of the sponge block 52.

[0037] Working principle: The operator fixes the dissolved oxygen sensor probe to be cleaned on the probe lowering device 2, and then lowers the dissolved oxygen sensor probe by starting the first linear driver 21 through the control panel 7. The operator observes through the observation window whether the dissolved oxygen sensor probe has been lowered to the cleaning system 3. The operator starts the first pump body 32 to deliver water through the control panel 7, and sprays water through multiple water mist nozzles 33. The operator then starts the first motor 22 to drive the dissolved oxygen sensor probe to rotate, ensuring cleaning without dead angles.

[0038] The staff can stop the cleaning system 3 and the first motor 22 through the control panel 7, further control the first linear driver 21 to lower the dissolved oxygen sensor probe, and further control the two cleaning rollers 41 of the cleaning system 4 to move towards the dissolved oxygen sensor probe through the observation window until the appropriate position is reached. Then, the first motor 22 and the second motor 42 are started to make the dissolved oxygen sensor probe and the cleaning rollers 41 rotate respectively, so as to clean the dissolved oxygen sensor probe without dead angles.

[0039] The cleaning system 4 stops driving the first linear actuator 21 to rise. When the dissolved oxygen sensor probe reaches the lowering hole, the wiping piece 5 extends and uses the sponge block 52 to wipe the dissolved oxygen sensor probe to remove water. Finally, the staff removes it to complete the cleaning.

[0040] The staff uses the control panel 7 to connect the two cleaning rollers 41 of the cleaning system 4 to the squeezing knife 9, and then drives the second motor 42 to perform reverse selection. In conjunction with the squeezing knife 9, the rollers squeeze in the opposite direction to completely remove the residual moisture and dirt inside the rollers. The liquid is then drained and cleaned by the bottom drainage system 6.
