Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of oil pollution detection, and particularly relates to a medicament circulating automatic cleaning and detection device with a self-cleaning device. BACKGROUND

[0002] The detection device is mainly used for detecting the concentration of oil pollutants in discharged water or surrounding seawater in real time. The detection device in the prior art mainly comprises a detection pool with a cavity, a detection device for detecting the oil content of a sample in the cavity, and a cleaning device for cleaning the inner wall of the detection pool and the detection device in the detection pool.

[0003] Generally, the cleaning device comprises a cleaning brush head for wiping the window of the infrared probe and a medicament circulating device for cleaning the inner wall of the detection pool. After the detection device detects the sample in the detection pool each time, the sample in the detection pool is discharged, and the window of the infrared probe is cleaned by the cleaning brush head. Every time, the medicament circulating device periodically cleans the entire inner wall of the detection pool.

[0004] In the above cleaning process, after the window of the infrared probe is wiped and cleaned by the cleaning brush head each time, the oil stains on the cleaning brush head are generally shaken off by rotating the cleaning brush head, so that the cleaning brush head is self-cleaned to continue cleaning the window of the infrared probe. However, the oil stains on the cleaning brush head cannot be removed by rotating the cleaning brush head to shake off the oil stains. When the window of the infrared probe needs to be cleaned again, the cleaning brush head cannot complete the cleaning work, which causes the line of sight of the window of the infrared probe to be blurred, the infrared probe cannot achieve accurate measurement, and the detection accuracy of the detection device is reduced. SUMMARY

[0005] The present application solves the problem of providing a medicament circulating automatic cleaning and detection device with a self-cleaning device, which can keep the cleaning brush head clean after cleaning once, continuously maintain the self-cleaning state when the window of the infrared probe is cleaned again, thereby improving the cleaning effect of the cleaning device on the window of the infrared probe, and enabling the infrared probe to perform accurate measurement and improving the detection accuracy of the detection device.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic cleaning and detection device for circulating medicine with a self-cleaning device, comprising a detection pool, the detection pool being a rectangular column with a cavity inside, a slider sliding vertically within the cavity, the slider dividing the cavity into a detection chamber and a receiving chamber, a monitoring component being provided at the center of opposite side walls of the detection chamber, a sealed glass window being provided outside the monitoring component, a cleaning component being provided at the top of the detection chamber away from the slider end, a medicine inlet being provided at the top side wall of the detection chamber away from the slider end, the medicine inlet being connected to one end of the medicine circulation component, the other end of the medicine circulation component being connected to a liquid outlet, the liquid outlet being located on the bottom surface of the detection chamber away from the slider end, a liquid inlet being provided on the bottom side of the detection chamber away from the slider end, the slider being connected to a driving mechanism, the driving mechanism being placed within the receiving chamber, the receiving chamber containing the detection component, the driving mechanism driving the slider to move closer to or away from the cleaning component, when the slider moves to the position closest to the cleaning component, at which point the detection chamber space is at its minimum, the cleaning component cleans the monitoring components on opposite sides.

[0007] Furthermore, the cleaning assembly includes a drive unit and a cleaning brush head. The drive unit is installed on the top cavity wall of the detection chamber away from the slider end. The cleaning brush head is coaxially fixedly connected to the output shaft of the drive unit and is coaxially arranged with the liquid outlet.

[0008] Furthermore, the cleaning brush head includes a brush head shaft, which is a cylinder, and the outer cylindrical surface of the brush head shaft is uniformly provided with a number of soft bristles.

[0009] Furthermore, a scraper is coaxially mounted on the output shaft of the drive unit.

When the slider moves to the position closest to the cleaning component, the four right-angle scrapers on the scraper correspond one-to-one with the four right angles arranged vertically in the detection cavity. The right-angle scrapers slide and abut against the cavity wall at the vertical corner of the detection cavity. Two limiting blocks are coaxially fixed on the output shaft of the drive unit, and the scraper is located between the two limiting blocks.

[0010] Further, the medicine circulating assembly comprises a medicine storage tank, a temporary storage tank is arranged in the medicine storage tank, a communication valve is arranged between the medicine storage tank and the temporary storage tank, the upper end of the temporary storage tank is connected with the medicine inlet through a medicine outlet pipe, the lower end of the temporary storage tank is connected with the liquid outlet through a liquid discharge pipe, a collection tank is further arranged on the medicine storage tank, the lower end of the collection tank is connected with one end of a collection pipe, the other end of the collection pipe is communicated with the liquid discharge pipe, the medicine outlet pipe and the collection pipe are both provided with pumps, a first electromagnetic valve is arranged on the liquid discharge pipe close to the liquid outlet, a second electromagnetic valve is arranged on the liquid discharge pipe close to the collection pipe, and a third electromagnetic valve is arranged on the collection pipe.

[0011] Further, the monitoring assembly comprises an infrared probe and an infrared receiver, the infrared probe is arranged on the inner wall of the detection cavity, the infrared receiver is arranged on the wall of the sliding block cavity, the infrared probe and the infrared receiver are arranged in relative positions along the length direction of the detection cavity, and the cavity wall of the detection cavity is further provided with the sealed glass window which shields and protects the infrared probe and the infrared receiver.

[0012] Further, the driving mechanism is an electric telescopic rod, one end of the output shaft of the electric telescopic rod is connected with the sliding block away from the infrared receiver, the electric telescopic rod is arranged in the containing cavity, the electric telescopic rod drives the upper and lower end faces of the sliding block to slide and abut against the upper and lower inner wall faces of the cavity, and a fluorine rubber layer is arranged between the sliding block and the cavity wall.

[0013] Further, the detection assembly comprises a detection frame, the detection frame is fixedly installed on the output shaft of the electric telescopic rod, the detection frame is arranged in the containing cavity, the detection frame is provided with a color sensor at the end away from the electric telescopic rod, and an oil stain detection test paper is arranged on the inner wall of the containing cavity; when the sliding block slides, the fluorine rubber layer slides and abuts against the oil stain detection test paper.

[0014] Further, the detection frame is four, the four detection frames are uniformly spaced and arranged in a "cross" shape around the output shaft of the electric telescopic rod, the color sensor is four, the four color sensors correspond to the four detection frames one by one, and the oil stain detection test paper is four, the four oil stain detection test papers correspond to the four cavity walls of the containing cavity one by one.

[0015] Further, the detection pool is a flat cuboid, the length and height dimensions of the cavity are both greater than the width dimension of the cavity, the width dimension of the cavity is greater than the diameter of the brush shaft, and the width dimension of the cavity is less than or equal to the outer diameter of the cleaning brush head.

[0016] The application has the advantages and positive effects that:

[0017] 1. This invention utilizes an electric telescopic rod and a slider. After the monitoring component monitors the oil content of the sample in the detection chamber, the sample is discharged from the outlet. The electric telescopic rod extends, pushing the slider to the position closest to the cleaning component. During this movement, the slider pushes the residual sample in the detection chamber towards the outlet, pre-treating the sample residue. The reagent circulation component delivers the reagent into the detection chamber through the inlet. The drive unit is activated, causing the cleaning brush head to rotate and move downwards. The cleaning brush head cleans the sample residue on the detection chamber walls and the sealed glass window. The rotating cleaning brush head in the reagent agitates the reagent within the detection chamber, creating a vortex. This vortex provides a better flushing effect on the chamber walls, resulting in a cleaner detection chamber and a more thorough cleaning of the cleaning brush head. This ensures that the inner walls of the detection chamber and the sealed glass window are thoroughly cleaned during subsequent cleaning, significantly reducing measurement inaccuracies caused by obstruction of the sealed glass window. Furthermore, the more thorough cleaning of residual sample within the detection chamber improves the accuracy of subsequent sample testing.

[0018] 2. This invention features a storage tank and a collection pipe. After each cleaning cycle, the monitoring device detects the residual cleaning liquid to determine if the oil content exceeds a predetermined value. This determines whether the efficacy of the batch of medicine has been fully realized. When the efficacy is fully realized, the residual cleaning liquid is discharged into the collection tank. When the efficacy is not fully realized, the residual cleaning liquid re-enters the detection chamber through a temporary storage tank in the storage tank. This cycle continues until the efficacy of the batch of medicine is fully realized, significantly saving medicine resources. Furthermore, the slider design results in a relatively small detection chamber space during cleaning, requiring less medicine to clean the inner wall of the cavity, further reducing waste of medicine resources.

[0019] 3. This invention features a fluororubber layer at the contact point between the slider and the cavity wall. This layer effectively pushes any remaining sample within the detection cavity to the outlet, significantly improving the cleaning effect on the cavity's inner wall. Simultaneously, the fluororubber layer seals the gaps between the slider and the cavity wall, ensuring the detection cavity remains relatively sealed and minimizing sample or cleaning residue leakage, thus enhancing the equipment's operational stability.

[0020] 4. The detection component of the present invention monitors the sealing of the detection chamber in real time. When a leak of sample or cleaning residue is detected, the equipment immediately stops working and discharges the sample or cleaning residue in the detection chamber into the collection tank to prevent further leakage of sample or cleaning residue. The system issues an alarm to notify the staff to carry out repairs. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] The embodiments of the present application will be further described below in conjunction with the drawings:

[0038] As shown in Figure 1 , Figure 2 , a medicament circulating automatic cleaning and detection device with self-cleaning device, comprising a detection pool 1, the detection pool 1 is a rectangular columnar body, the detection pool 1 is provided with a cavity, a sliding block 41 is vertically arranged in the cavity, and the sliding block 41 divides the cavity into a detection cavity 11 and a containing cavity 12. The detection cavity 11 is provided with a monitoring assembly 2 at the center of the opposite side wall surface, and the monitoring assembly 2 is provided with a sealed glass window 23 outside. The detection cavity 11 is provided with a cleaning assembly 3 at the top of the end away from the sliding block 41, and the detection cavity 11 is provided with a medicine inlet 15 at the side wall of the bottom of the end away from the sliding block 41. The medicine inlet 15 is connected to one end of a medicament circulating assembly 6, and the other end of the medicament circulating assembly 6 is connected to a liquid outlet 14. The liquid outlet 14 is arranged at the bottom of the end of the detection cavity 11 away from the sliding block 41, and the detection cavity 11 is provided with a liquid inlet 13 at the side of the bottom of the end away from the sliding block 41. The sliding block 41 is connected to a driving mechanism 4, and the driving mechanism 4 is arranged in the containing cavity 12. The containing cavity 12 is provided with a detection assembly 5, which detects whether there is a leakage in the detection cavity 11. The driving mechanism 4 drives the sliding block 41 to move close to or away from the cleaning assembly 3. When the sliding block 41 moves to the position closest to the cleaning assembly 3, the space of the detection cavity 11 is smallest at this time, and the cleaning assembly 3 cleans the two monitoring assemblies 2 on the opposite sides.

[0039] As shown in Figure 1 , the detection pool 1 is a flat rectangular body, and the length and height dimensions of the cavity are much larger than the width dimension of the cavity. As shown in Figure 2As shown, the cavity width dimension is greater than the brush head shaft diameter, and the cavity width dimension is less than or equal to the outer diameter of the cleaning brush head 31. When the cleaning brush head 31 is cleaned, it can touch the four side walls of the detection cavity 11.

[0040] It should be noted that the cavity 11 in the detection pool 1 in the embodiment is designed in a flat rectangular shape based on the Beer-Lambert Law and fluid dynamics. The formula of the Beer-Lambert Law is A = αlc, where A is the absorbance (directly related to the detection signal strength), α is the molar absorption coefficient (an inherent property of oil at a specific wavelength), c is the oil concentration, and l is the optical path (the path length of light passing through the sample). The flat structure of the rectangular flat pool (aspect ratio > 5:1) promotes laminar flow and avoids turbulence caused by bubbles or particles, so in order to ensure the absorbance and avoid turbulence as much as possible, the rectangular flat pool structure is used in the embodiment and in the prior art. However, this structure is relatively long and has many corners, so it requires more chemicals for cleaning and the cleaning process is relatively more troublesome, i.e., it is difficult to clean completely. In the embodiment, the space size of the detection cavity 11 in the detection pool 1 is adjusted to be at a maximum during detection to ensure that the optical path is sufficient, i.e., to ensure the absorbance, thereby ensuring the detection accuracy of the equipment. After detection, the space size of the detection cavity 11 is at a minimum, so the amount of chemicals required is reduced, and the cleaning brush head 31 is more convenient for cleaning the cavity wall and the sealed glass window 23 of the detection cavity 11.

[0041] As shown in Figure 2 The detection pool 1 is provided with a liquid inlet 13 and a liquid outlet 14, both of which communicate with the detection cavity 11. The liquid inlet 13 is arranged along the width direction of the detection cavity 11, and the lowest part of the liquid inlet 13 is at the same horizontal line as the bottom of the detection cavity 11, and the liquid inlet 13 is horizontally located inside the detection cavity 11 close to the end of the cleaning assembly 3. The liquid outlet 14 is arranged along the height direction of the detection cavity 11, and the liquid outlet 14 communicates with the bottom of the detection cavity 11. The horizontal direction of the liquid outlet 14 is also located inside the detection cavity 11 close to the end of the cleaning assembly 3.

[0042] As shown in Figure 2 The monitoring assembly 2 includes an infrared probe 21 and an infrared receiver 22. The infrared probe 21 is arranged on the inner wall of the detection cavity 11, and the infrared receiver 22 is arranged in the cavity wall of the sliding block 41. The infrared probe 21 and the infrared receiver 22 are arranged in opposite directions along the length direction of the detection cavity 11. The detection cavity 11 is also provided with a sealed glass window 23 for blocking and protecting the infrared probe 21 and the infrared receiver 22. The sealed glass window 23 is installed on the inner wall of the detection cavity 11, and the sealed glass window 23 and the cavity wall of the detection cavity 11 are in the same plane.

[0043] As Figure 3 , Figure 4 shown, the cleaning assembly 3 comprises a driving member 32 and a cleaning brush head 31, and the driving member 32 in this embodiment is a linear rotary motor, which can drive the object to rotate around the axis and move linearly along the axis. The driving member 32 is installed on the top cavity wall of the detection cavity 11 away from the sliding block 41, the cleaning brush head 31 is coaxially fixedly connected with the output shaft of the driving member 32, the cleaning brush head 31 is coaxially arranged with the liquid outlet 14, the driving member 32 drives the cleaning brush head 31 to move downward and rotate around its own axis, and the cleaning brush head 31 slides against the sealing glass window 23 during the downward movement of the cleaning brush head 31.

[0044] As Figure 4 shown, the cleaning brush head 31 comprises a brush head shaft, which is a cylinder, and a plurality of soft hairs are uniformly arranged on the outer cylindrical surface of the brush head shaft. As Figure 3 shown, the width of the detection cavity 11 is greater than the diameter of the brush head shaft and slightly smaller than the outer diameter of the cleaning brush head 31, so that the soft hairs of the cleaning brush head 31 can simultaneously touch the two inner cavity walls of the detection cavity 11 arranged along the width direction. When the sliding block 41 moves to the position closest to the cleaning assembly 3, the space of the detection cavity 11 is smallest at this time, and the soft hairs of the cleaning brush head 31 can simultaneously touch the four cavity wall surfaces of the detection cavity 11 and the sealing glass window 23 on the cavity wall at this time. The arrangement of the soft hairs can avoid the situation that the sealing glass window 23 and the cavity wall of the detection cavity 11 are scratched by the cleaning brush head 31, and at the same time, there is a certain gap between the soft hairs on the cleaning brush head 31 and the soft hairs. When the cleaning brush head 31 rotates, the soft hairs on the cleaning brush head 31 can also be separated from each other under the action of centrifugal force, so that there will be a gap between the soft hairs and the soft hairs. At this time, the cleaning brush head 31 rotates in the medicament, and the medicament can better penetrate into the gap between the soft hairs and the soft hairs, so as to better wash away the oil stains on the soft hairs, thereby improving the self-cleaning effect of the cleaning brush head 31.

[0045] Preferably, a scraper 33 is coaxially arranged on the output shaft of the driving member 32, the scraper 33 is arranged in the shape of a cross, and the scraper 33 is provided with right-angle scraping blocks at the ends. When the sliding block 41 moves to the position closest to the cleaning assembly 3, the space of the detection cavity 11 is smallest at this time, and the four right-angle scraping blocks on the scraper 33 correspond to the four right-angle corners of the detection cavity 11 arranged in the vertical direction one by one, and the right-angle scraping blocks slide against the cavity walls of the detection cavity 11 at the corners in the vertical direction. The scraper 33 is located above the cleaning brush head 31, two limiting blocks 34 are coaxially and fixedly arranged on the output shaft of the driving member 32, the scraper 33 is located between the two limiting blocks 34, and the arrangement of the two limiting blocks 34 prevents the relative sliding of the scraper 33 and the output shaft of the linear rotary motor in the vertical direction.

[0046] When the driving member 32 drives the cleaning brush head 31 to rotate, since the scraping frame 33 is sleeved on the output shaft of the linear rotating motor, the scraping frame 33 will not rotate with the linear rotating motor, and then when the linear rotating motor drives the cleaning brush head 31 to move up and down, due to the limiting effect of the two limiting blocks 34, the linear rotating motor also drives the scraping frame 33 to move up and down, and the up and down movement of the scraping frame 33 drives the four right-angle scraping blocks of the scraping frame 33 to move up and down, and since the right-angle scraping blocks of the scraping frame 33 abut against the corners arranged in the vertical direction in the detection cavity 11, when the right-angle scraping blocks on the scraping frame 33 move up and down, the right-angle scraping blocks of the scraping frame 33 can scrape off the oil stains at the corners in the detection cavity 11, which are difficult to be contacted by the cleaning brush head 31 and thus difficult to be cleaned by the cleaning brush head 31, so that the scraping frame 33 can clean the oil stains at the corners in the detection cavity 11, and thus the scraping frame 33 cooperating with the cleaning brush head 31 can clean the oil stains on the cavity wall of the detection cavity 11 more thoroughly.

[0047] As shown in Figure 5 , Figure 6 , the driving mechanism 4 is an electric telescopic rod 42, the output shaft of the electric telescopic rod 42 is connected to the end of the sliding block 41 away from the infrared receiver 22, the electric telescopic rod 42 is arranged in the containing cavity 12, the electric telescopic rod 42 drives the upper and lower end surfaces of the sliding block 41 to slide and abut against the upper and lower inner wall surfaces of the cavity, and the space sizes of the detection cavity 11 and the containing groove 12 change along with the sliding of the sliding block 41, when the sliding block 41 moves in the direction close to the infrared probe 21, the space of the containing groove 12 increases and the space of the detection cavity 11 decreases, and vice versa, when the sliding block 41 slides in the direction close to the infrared receiver 22, the space of the containing groove 12 decreases and the space of the detection cavity 11 increases. It should be noted that in the embodiment, when the sliding block 41 slides to the end closest to the cleaning assembly 3, the sliding block 41 will not block the liquid inlet 13 and the liquid outlet 14 due to the brush head shaft, at this time, when the driving member 32 drives the cleaning brush head 31 to move down, the cleaning brush head 31 can just touch the sealed glass window 23 at the infrared probe 21 and the sealed glass window 23 at the infrared receiver 22.

[0048] Preferably, the fluororubber layer 43 is arranged between the sliding block 41 and the cavity wall. The fluororubber layer 43 has a certain elasticity, so that the fluororubber layer 43 can well block the gap between the sliding block 41 and the cavity wall, thereby avoiding the oil stain in the detection cavity 11 from leaking into the containing groove 12 as much as possible. At the same time, the fluororubber layer 43 can avoid metal friction between the sliding block 41 and the cavity wall, thereby reducing the probability of wear of the sliding block 41 and the detection pool 1, and increasing the service life of the sliding block 41 and the detection pool 1. In addition, the fluororubber layer 43 in the embodiment has good oil repellency and corrosion resistance, so that in the process of moving the sliding block 41 close to the infrared probe 21, the fluororubber layer 43 can well scrape the oil stain attached to the cavity wall in the direction close to the liquid outlet 14, further improving the cleaning effect of the oil stain in the cavity wall, and the corrosion resistance of the fluororubber layer 43 itself is more suitable for offshore platforms and saline-alkali lands.

[0049] As shown in Figure 2 The medicament circulating assembly 6 is arranged beside the detection pool 1, the detection pool 1 is provided with a medicament inlet 15 communicating with the detection cavity 11, the liquid inlet 13 is arranged above the cleaning brush head 31, the medicament circulating assembly 6 is communicated with the medicament inlet 15 through a pipeline, and the other end of the medicament circulating assembly 6 is also communicated with the liquid outlet 14 through a pipeline.

[0050] The medicament circulating assembly 6 comprises a medicament storage tank 61, the medicament storage tank 61 is provided with a temporary storage tank 69, a communication valve 611 is arranged between the medicament storage tank 61 and the temporary storage tank 69, the upper end of the temporary storage tank 69 is connected with the medicament inlet 15 through a medicament outlet pipe 62, the lower end of the temporary storage tank 69 is connected with the liquid outlet 14 through a liquid discharge pipe 63, the medicament storage tank 61 is further provided with a collection tank 65, the lower end of the collection tank 65 is connected with one end of a collection pipe 66, the other end of the collection pipe 66 is communicated with the liquid discharge pipe 63, the medicament outlet pipe 62 and the collection pipe 66 are both provided with a pump 64, the first electromagnetic valve 67 is arranged on the liquid discharge pipe 63 close to the liquid outlet 14, the second electromagnetic valve 68 is arranged on the liquid discharge pipe 63 close to the collection pipe 66, and the third electromagnetic valve 610 is arranged on the collection pipe 66.

[0051] When the sample needs to be detected, the first electromagnetic valve 67, the second electromagnetic valve 68, the third electromagnetic valve 610 and the communication valve 611 are closed, the sample is filled into the detection cavity 11, and after the detection is completed, the first electromagnetic valve 67, the third electromagnetic valve 610 and the pump 64 on the collection tank 65 are opened, and the detected sample enters into the collection tank 65 through the liquid outlet 14, the liquid discharge pipe 63 and the collection pipe 66 in sequence. When the sliding block 41 moves to the rightmost end of the detection cavity 11, the first electromagnetic valve 67, the third electromagnetic valve 610 and the pump 64 on the collection tank 65 are closed, and then the communication valve 611 and the pump 64 on the medicine outlet pipe 62 are opened, and the medicine in the medicine storage tank 61 enters into the detection cavity 11 through the temporary storage tank 69, the medicine outlet pipe 62 and the medicine inlet 15 in sequence. After a certain amount of medicine enters into the detection cavity 11, the communication valve 611 and the pump 64 on the medicine outlet pipe 62 are closed in sequence, and after the cleaning brush head 31 cleans the residual sample in the detection cavity 11, the infrared probe 21 and the infrared receiver 22 detect the cleaning residual liquid in the detection cavity 11 at this time, and then determine whether the medicine in the cleaning residual liquid at this time meets the content required for the next cleaning work according to the oil concentration in the cleaning residual liquid. If it meets the requirement, the first electromagnetic valve 67 and the second electromagnetic valve 68 are opened, and then the cleaning residual liquid meeting the requirement flows into the temporary storage tank 69 for use in the next cleaning work. If it does not meet the requirement, the cleaning residual liquid is discharged into the collection pipe 66 by opening the first electromagnetic valve 67, the third electromagnetic valve 610 and the pump 64 on the collection pipe 66, and then the above operation is repeated. In this process, the cleaning residual liquid meeting the requirement can be continuously used, and the cleaning residual liquid not meeting the requirement is collected by the collection tank 65, and then new medicine is guided from the medicine storage tank 61 for use, which greatly improves the utilization rate of the medicine and avoids the waste of the medicine resources as much as possible.

[0052] As shown in Figure 2 The detection assembly 5 for detecting whether the detection cavity 11 has a leakage is further arranged in the containing groove 12 in the embodiment. The detection assembly 5 includes a detection frame 51, the detection frame 51 is fixedly installed on the output shaft of the electric telescopic rod 42, the detection frame 51 is arranged in the containing cavity 12, the detection frame 51 is provided with a color sensor 52 at the end away from the electric telescopic rod 42, and the oil stain detection test paper 53 is arranged on the inner wall of the containing cavity 12. When the sliding block 41 slides, the fluorine rubber layer 43 slides and abuts against the oil stain detection test paper 53.

[0053] The detection frame 51 is four, and the four detection frames 51 are arranged in a “cross” shape and are uniformly spaced around the output shaft of the electric telescopic rod 42. The color sensor 52 is four, and the four color sensors 52 correspond to the four detection frames 51 one by one. The oil stain detection test paper 53 is four, and the four oil stain detection test papers 53 correspond to the four cavity walls of the containing cavity 12 one by one.

[0054] When a leak occurs inside the detection cavity 11, the oil stain inside the detection cavity 11 can easily penetrate into the gap between the sliding block 41 and the cavity wall of the detection cavity 11, so when the sliding block 41 moves in the direction close to the infrared probe 21, i.e. the space of the containing groove 12 is enlarged, the space of the detection cavity 11 is reduced, and if the oil stain inside the detection cavity 11 penetrates into the gap between the sliding block 41 and the cavity wall of the detection cavity 11. When the sliding block 41 moves in the direction away from the infrared probe 21, i.e. the sliding block 41 moves back, the end surface of the sliding block 41 in contact with the groove wall of the containing groove 12 will carry the oil stain, and when the sliding block 41 moves back to the original position, the oil stain detection test paper 53 inside the containing groove 12 is between the sliding block 41 and the groove wall of the containing groove 12. Therefore, the oil stain on the sliding block 41 will adhere to the oil stain detection test paper 53, and after the oil stain detection test paper 53 contacts the oil stain, the color of its surface will change, and when the sliding block 41 moves in the direction close to the infrared probe 21 next time, the electric telescopic rod 42 will also drive the detection frame 51 to pass through the oil stain detection test paper 53, and the color sensor 52 on the detection frame 51 can detect the color change of the oil stain detection test paper 53, so that the color sensor 52 transmits the signal to the control center, and the control center stops the equipment operation immediately and sends an alarm to the staff for timely maintenance of the equipment. If the color sensor 52 does not detect the color change of the oil stain detection test paper 53, the equipment will continue to run stably.

[0055] The working principle of the present application is as follows:

[0056] When it is necessary to detect whether the discharged water meets the standard, part of the sample is poured into the detection cavity 11 from the liquid inlet 13 on the detection pool 1, at this time the space of the detection cavity 11 is at the maximum, i.e. the sliding block 41 is located at the end closest to the driving mechanism 4 in the detection cavity 11, and at this time the space of the containing cavity 12 is the smallest. After the detection cavity 11 inputs the sample in a certain amount, the glass window at the infrared probe 21 and the sealed glass window 23 at the infrared receiver 22 are immersed in the sample, then the infrared probe 21 emits light, the light passes through the sample and reaches the infrared receiver 22, after the light passes through the sample, the oil stain in the sample will affect the strength, wavelength and other properties of the light, therefore the infrared receiver 22 will collect the light after passing through the sample and transmit the collected data to the control center for analysis, so as to compare the collected data with the original data, and then obtain the content of the oil stain in the sample.

[0057] After the detection is completed, the channel between the outlet 14 and the medicament circulating assembly 6 is opened, and then the sample in the detection cavity 11 that has been detected is discharged from the outlet 14. The electric telescopic rod 42 is started, and the electric telescopic rod 42 is elongated to drive the sliding block 41 to move in the direction close to the infrared probe 21. During the movement of the sliding block 41, the sliding block 41 pushes the residual sample in the detection cavity 11 to the outlet 14, so as to clean the residual sample in the detection cavity 11. The sliding block 41 is in sliding abutment with the cavity wall of the detection cavity 11, so that the sliding block 41 scrapes the residual sample on the cavity wall of the detection cavity 11 to the outlet 14 during the movement. With the movement of the sliding block 41, the space of the detection cavity 11 becomes smaller and smaller, that is, the sliding block 41 concentrates all the residual sample in the detection cavity 11 close to the outlet 14 end of the detection cavity 11. When the sliding block 41 moves to the smallest space of the detection cavity 11, the channel between the outlet 14 and the medicament circulating assembly 6 is closed, and the circulating medicament assembly pours the medicament from the medicament inlet 15 into the detection cavity 11 at this time. After the quantitative medicament is poured, the driving member 32 is started, and the driving member 32 drives the cleaning brush head 31 to rotate. Since the cleaning brush head 31 can simultaneously touch the sealed glass window 23 at the infrared probe 21 and the sealed glass window 23 at the infrared receiver 22 and the plane of the sealed glass window 23 and the cavity wall during the downward movement of the cleaning brush head 31. The cleaning brush head 31 can simultaneously contact the cavity wall of the detection cavity 11 where the infrared probe 21 is located, the cavity wall of the detection cavity 11 where the infrared receiver 22 is located, and the two cavity walls arranged along the width direction of the detection cavity 11. When the linear motor starts to rotate the cleaning brush head 31, the cleaning brush head 31 can clean the cavity wall of the detection cavity 11 at this time. With the downward movement of the linear motor driving the cleaning brush head 31, the cleaning brush head 31 can clean the cavity wall of the entire detection cavity 11, clean the sealed glass window 23 on the cavity wall, and dissolve the oil stains on the cavity wall and the sealed glass window 23 by the medicament in the detection cavity 11. Therefore, under the dual action of the cleaning brush head 31 and the medicament, the oil stains on the cavity wall and the sealed glass window 23 of the detection cavity 11 can be cleaned more thoroughly. In addition, the cleaning brush head 31 is also immersed in the medicament, and the medicament can also dissolve the oil stains adhered to the cleaning brush head 31. The cleaning brush head 31 is in a rotating state in the medicament at all times, so that the cleaning brush head 31 can make the medicament in the detection cavity 11 generate vortex flow, which can flush the cavity wall of the detection cavity 11 and the sealed glass window 23, thereby further improving the cleaning effect of the cavity wall of the detection cavity 11 and the sealed glass window 23.In addition, the cleaning brush head 31 is in friction with the medicament while rotating in the medicament, so the medicament can also wash away the oil stains on the cleaning brush head 31, thereby achieving the self-cleaning effect of the cleaning brush head 31. Compared with the prior art in which the cleaning brush head 31 is driven to rotate to remove the oil stains on the cleaning brush head 31 by centrifugal force, the chemical dissolution of the medicament and the washing effect of the medicament on the cleaning brush head 31 in the embodiment are better for cleaning the cleaning brush head 31.

[0058] In general, the space of the detection cavity 11 is reduced by the sliding block 41, and during the reduction of the space of the detection cavity 11, the sliding block 41 can push all the residual samples in the detection cavity 11 to the end of the detection cavity 11 closest to the liquid outlet 14, so that part of the residual samples are directly discharged from the detection cavity 11 through the liquid outlet 14, and the remaining part of the residual samples are concentrated in the detection cavity 11 with a relatively small space. At this time, a small amount of medicament is injected into the detection cavity 11 with a small space, so that the medicament can dissolve the oil stains on the cavity wall of the detection cavity 11 and the sealing glass window 23. At this time, since the space of the detection cavity 11 is small, the cleaning brush head 31 can not only contact the sealing glass window 23 at the infrared probe 21 and the infrared receiver 22, but also almost contact all the walls of the detection cavity 11. Therefore, the cleaning brush head 31 can clean the cavity wall and the sealing glass window 23 of the detection cavity 11. In addition, the cleaning brush head 31 can also achieve self-cleaning during the cleaning of the cavity wall and the sealing glass window 23 of the detection cavity 11, so that it has a good cleaning effect on the entire detection cavity 11 and the components inside the detection cavity 11. Therefore, the probability of residual samples in the detection cavity 11 is small, so that the actual content of oil stains in the next sample will not be affected by the residual samples in the detection cavity 11 during the next detection, so that the detection device can accurately measure the actual content of oil stains in each sample, thereby greatly improving the detection precision of the device.

[0059] The present application has the advantages and positive effects that:

[0060] 1. This invention utilizes an electric telescopic rod and a slider. After the monitoring component monitors the oil content of the sample in the detection chamber, the sample is discharged from the outlet. The electric telescopic rod extends, pushing the slider to the position closest to the cleaning component. During this movement, the slider pushes the residual sample in the detection chamber towards the outlet, pre-treating the sample residue. The reagent circulation component delivers the reagent into the detection chamber through the inlet. The drive unit is activated, causing the cleaning brush head to rotate and move downwards. The cleaning brush head cleans the sample residue on the detection chamber walls and the sealed glass window. The rotating cleaning brush head in the reagent agitates the reagent within the detection chamber, creating a vortex. This vortex provides a better flushing effect on the chamber walls, resulting in a cleaner detection chamber and a more thorough cleaning of the cleaning brush head. This ensures that the inner walls of the detection chamber and the sealed glass window are thoroughly cleaned during subsequent cleaning, significantly reducing measurement inaccuracies caused by obstruction of the sealed glass window. Furthermore, the more thorough cleaning of residual sample within the detection chamber improves the accuracy of subsequent sample testing.

[0061] 2. This invention features a storage tank and a collection pipe. After each cleaning cycle, the monitoring device detects the residual cleaning liquid to determine if the oil content exceeds a predetermined value. This determines whether the efficacy of the batch of medication has been fully realized. When the efficacy is fully realized, the residual cleaning liquid is discharged into the collection tank. When the efficacy is not fully realized, the residual cleaning liquid re-enters the detection chamber through a temporary storage tank in the storage tank. This cycle continues until the efficacy of the batch of medication is fully realized, significantly saving medication resources. Furthermore, the slider design results in a relatively small detection chamber space during the cleaning process, requiring less medication to clean the inner wall of the detection chamber, further reducing waste of medication resources.

[0062] 3. This invention features a fluororubber layer at the contact point between the slider and the cavity wall. This layer effectively pushes any remaining sample within the detection cavity to the outlet, significantly improving the cleaning effect on the cavity's inner wall. Simultaneously, the fluororubber layer seals the gaps between the slider and the cavity wall, ensuring the detection cavity remains relatively sealed and minimizing sample or cleaning residue leakage, thus enhancing the equipment's operational stability.

[0063] 4. The detection component of the present invention monitors the sealing of the detection chamber in real time. When a leak of sample or cleaning residue is detected, the equipment immediately stops working and discharges the sample or cleaning residue in the detection chamber into the collection tank to prevent further leakage of sample or cleaning residue. The system issues an alarm to notify the staff to carry out repairs.

[0064] The above has been described in detail one embodiment of the present application, but the content is only the preferred embodiment of the present application, cannot be considered for limiting the scope of the present application. Any equivalent changes and improvements made in the scope of the present application, should still belong to the scope of the present application.
