Description

Technical Field

[0001] The present invention relates to the technical field of antibiotic detection, and particularly relates to a sampling device for detecting antibiotics in sewage. Background Art

[0002] With the wide application of antibiotics in industries such as medical and health, livestock and poultry breeding, and agricultural production, the problem of their residues has become increasingly prominent.

The present invention traces the source of areas where antibiotics are abused by analyzing the detection results within the same time period.

[0005] However, the sampling results of this patent all come from the sampling area at the same location, and the sampling results are single, which may lead to deviations in the detection results and thus affect the accurate assessment of the antibiotic residue situation in the environment.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Summary of the Invention

Detailed implementation manners

[0036] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below. Apparently, the described embodiments are some but not all of the embodiments of the present invention.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0038] As Figures 1 to 11As shown in the figure, a sampling device for detecting antibiotics in sewage according to the present invention includes: a detection device 1, a sampling mechanism 3 for sampling sewage, and a mounting frame 2. The mounting frame 2 is fixedly installed on the detection device 1. During use, the mounting frame 2 is fixed at the detection location by screws to prevent the device from shaking during sampling and detection, which may affect the sampling and detection results. Then, the sewage is sampled by the sampling mechanism 3 and sent into the detection device 1 for detection. The detection device 1 is a professional aquatic product antibiotic detector to ensure the detection effect of the sewage.

[0039] The sampling mechanism 3 includes: a sampling tube 31, a sampling bottle 3124 for storing the sampling results. There are multiple groups of sampling bottles 3124 to isolate the sampling results of each time, avoiding interference between multiple sampling results and affecting the detection results. An adjustment component 312 for adjusting the position of the sampling bottle 3124, a power source 311 for driving the adjustment component 312 to move axially along the sampling tube 31, and a stirring component 32 for stirring the sewage; the sampling bottle 3124 is moved out of the sampling tube 31, and then under the action of the power source 311, the sampling bottle 3124 is moved out of the sampling tube 31 and into the sewage for sampling. The power source 311 is preferably an electric telescopic rod. In addition, when the power source 311 drives the sampling bottle 3124 to move, it can also drive multiple groups of sampling bottles 3124 to switch under the action of the adjustment component 312, thereby realizing multiple samplings of the same sewage at different depths by switching different sampling bottles 3124 to ensure the diversity of the sampling results and more accurately reflect the antibiotic residue situation in the sewage.

[0040] Specifically, the adjustment component 312 includes: an adjustment plate 3121, the adjustment plate 3121 is fixedly installed at the output end of the power source 311, and a guide block 31212 is fixedly installed on the adjustment plate 3121; the guide block 31212 is slidably connected to the guide groove 3126, a connecting rod 3122 fixedly installed on the adjustment plate 3121, a fixing member 3123 fixedly installed on the connecting rod 3122, a filter plate 3125 for filtering impurities in the sewage. The other side of the filter plate 3125 is provided with filter holes 31257, a guide groove 3126 and an adjustment groove 3127 are provided on the inner wall of the sampling tube 31; the adjustment groove 3127 is an arc-shaped groove, the guide groove 3126 is a straight groove, and multiple groups of straight grooves are provided on the sampling tube 31. The arc-shaped groove connects two adjacent straight grooves (as Figure 5 , Figure 11 shown).

[0041] When in use, the power source 311 drives the adjustment plate 3121 to move inside the sampling tube 31, and the adjustment plate 3121 moves in the adjustment groove 3127 through the guide block 31212, and drives the sampling bottle 3124 to move in the direction of the sewage through the connecting rod 3122 and the fixing part 3123 to sample, and the sewage enters the liquid inlet 31254 through the filter hole 31257 on the filter plate 3125, and then enters the sampling bottle 3124 to complete the sampling of the sewage. In addition, a solenoid valve can be set at the liquid inlet 31254 to control the inlet and outlet of sewage. When the power source 311 drives the sampling bottle 3124 to move to different positions in the sewage, the solenoid valve opens to sample the sewage. Sampling is helpful to sample different depths of sewage, improve the diversity of sampling results, and ensure the accuracy of detection after sampling. Specifically, when the sampling bottle 3124 extends out from the sampling tube 31 during sampling, the filter plate 3125 can filter out larger impurities in the water body on the one hand, ensuring that the sampling bottle 3124 will not be blocked and affect the sampling effect. On the other hand, the sampling bottle 3124 is retracted into the sampling tube 31 after sampling. At this time, the filter plate 3125 can seal the opening of the sampling tube 31 to prevent foreign matter from entering the sampling tube 31 and damaging the sampling bottle 3124, thereby ensuring the safety of the sampling bottle 3124 and greatly improving the practicality of the present application.

[0042] It should be noted that when the adjustment plate 3121 moves, the guide block 31212 and the adjustment groove 3127 are limited to ensure stability during movement. When the sampling bottle 3124 needs to be switched, the power source 311 is started to drive the sampling bottle 3124 to continue to move upward so that the guide block 31212 enters the adjustment groove 3127 from the guide groove 3126. Under the guidance of the adjustment groove 3127, the adjustment plate 3121 is driven to rotate through the guide block 31212, so that the sampling bottle 3124 that has completed sampling is rotated to the detection position, and the sampling bottle 3124 that has not been sampled is transferred to the sampling position, completing the conversion of the sampling bottle 3124. Then, if sampling needs to continue, the above steps are repeated. That is to say, when the power source 311 drives the sampling bottle 3124 to move, on the one hand, it can drive the sampling bottle 3124 to enter the sewage for sampling, and on the other hand, it can drive the sampling bottle 3124 to change its position so as to replace the unused sampling bottle 3124 for secondary sampling of the sewage. On the one hand, it can avoid the sewage remaining in the sampling bottle 3124 during the initial sampling from polluting the sewage remaining in the sampling bottle 3124 during the subsequent sampling. On the other hand, multiple sewage sampling can increase the accuracy of sewage sampling, eliminate factors that affect the test results as much as possible, and obtain samples that reflect the antibiotic residue situation in the environment or substance to be tested as truly as possible, thereby ensuring the accuracy of antibiotic test results.

[0043] What needs to be added to the above is that the sampling bottle 3124 is detachably installed on the fixing member 3123. The fixing member 3123 is a plastic clip, which facilitates the disassembly of the sampling bottle 3124. An installation plate 3111 is fixedly installed on the power source 311, and a push rod 3112 is fixedly installed on the installation plate 3111. The installation plate 3111 is fixedly installed on the inner wall of the sampling pipe 31. A drain pipe 3113 is connected to the sampling pipe 31, and the drain pipe 3113 is connected to the detection device 1. The sampling pipe 31 is fixedly installed on the detection device 1. An outlet 31241 is opened on the sampling bottle 3124, and a positioning hole 31211 is opened on the adjusting plate 3121. When the sampling bottle 3124 is transferred from the sampling position to the detection position, the position of the positioning hole 31211 on the adjusting plate 3121 corresponds to the position of the push rod 3112. At this time, the power source 311 continues to pull the adjusting plate 3121 upward, so that the push rod 3112 passes through the positioning hole 31211 and presses the sampling bottle 3124, and the water sample in the sampling bottle 3124 is discharged from the outlet 31241 to the drain pipe 3113, and finally is transported to the inside of the detection device 1 for detection.

[0044] That is to say, when the power source 311 pulls the sampling bottle 3124 for position adjustment, on the one hand, it can drive the position transfer of the sampling bottle 3124 that has not been sampled and the sampling bottle 3124 after sampling is completed, and on the other hand, it can discharge the water sample in the sampling bottle 3124 after sampling is completed for detection, and the use effect is good. The installation plate 3111 can provide a stable connection between the power source 311 and the sampling pipe 31 on the one hand, ensure that the power source 311 does not shake during use, and can install the push rod 3112 on the other hand, and the practicability is good.

[0045] As a further extension of the present application, an opening is provided at the end of the sampling bottle 3124 close to the push rod 3112, and a pressing plate is slidably connected at the opening. It is ensured that when the sampling bottle 3124 moves upward and contacts the push rod 3112, the push rod 3112 pushes the pressing plate to discharge the liquid in the sampling bottle 3124, ensuring that the water liquid can stably enter the inside of the detection device 1 for detection. Distance sensors are installed on both the pressing plate and the other end of the sampling bottle 3124 to sense the water volume in the sampling bottle 3124 in real time. In addition, a filter screen is provided at the outlet 31241. When the water liquid in the sampling bottle 3124 is discharged, it will be filtered again through the filter screen, ensuring that no impurities will enter the detection device 1 in the water liquid, avoiding pipeline blockage affecting the water liquid flow and affecting the detection of the detection device 1.

[0046] The advantage of doing this is that, on the one hand, the water liquid is double-filtered by the filter plate 3125 and the filter screen to ensure that no impurities in the water liquid are input into the detection device 1, affecting the detection result. On the other hand, the impurities are filtered in the sampling bottle 3124. When the water liquid in the sampling bottle 3124 is completely drained, the distance between the bottom plate and the two groups of distance sensors at the other end of the sampling bottle 3124 is the impurity content in the water liquid. In this way, the impurity content in the sewage can be detected, and the detection effect of the sewage is good.

[0047] That is to say, when the power source 311 pulls the adjusting plate 3121 upward, on the one hand, it can make the ejector rod 3112 push the water liquid inside the sampling bottle 3124 out and transport it to the detection device 1 for detection. On the other hand, it can detect the impurity content filtered in the sampling bottle 3124, and the detection effect of the sewage is good.

[0048] In addition, to ensure that the guide block 31212 can stably move from the guide groove 3126 to the inside of the adjustment groove 3127, an inclined groove 31261 is opened on the guide groove 3126. A push block 31262 is slidably connected to the inclined groove 31261. An elastic block 31263 is fixedly connected to the push block 31262. One end of the elastic block 31263 abuts against the inclined groove 31261. A elastic cord is also fixedly installed on the push block 31262. One end of the elastic cord is fixedly connected to the inclined groove 31261 (not shown). When the guide block 31212 moves inside the guide groove 3126, it drives the push block 31262 to move in the inclined groove 31261. The depth of the inclined groove 31261 gradually increases from the direction of the power source 311 to the direction of the filter plate 3125. So that when the guide block 31212 moves downward, it pushes the push block 31262 to move inside the inclined groove 31261. At this time, the elastic cord is deformed by force. Affected by the inclined surface of the inclined groove 31261, the push block 31262 gradually enters the inclined groove 31261, making the chamfered surface of the guide block 31212 contact with the push block 31262. Under the guidance of the chamfered surface, the push block 31262 is squeezed to make the elastic block 31263 contract. At this time, the guide block 31212 can move downward normally. Then the elastic block 31263 resets to drive the push block 31262 to reset. The elastic cord resets to pull the push block 31262 upward. When the guide block 31212 moves upward from the guide groove 3126, blocked by the push block 31262, the guide block 31212 stably enters the inside of the adjustment groove 3127, ensuring the switching effect of the sampling bottle 3124 and the stability of the present application during sampling; the elastic block 31263 can be selected as a spring or a rubber block.

[0049] It should be added that the end face of the inclined groove 31261 close to the detection device 1 is the X surface, the side surface in contact with the elastic block 31263 is the Y surface. One end of the elastic cord is fixedly connected to the X surface, and the other end is fixedly connected to the push block 31262. When the push block 31262 slides, the elastic block 31263 slides on the Y surface.

[0050] When the adjusting plate 3121 rotates, it drives the connecting rod 3122 and the sampling bottle 3124 to rotate. Since the liquid inlet 31254 is provided on the filter plate 3125 and only one set of liquid inlets 31254 is provided, if the filter plate 3125 rotates with the adjusting plate 3121, the liquid inlet 31254 will move accordingly, causing the other multiple sets of sampling bottles 3124 to be unable to take samples. Therefore, a fixing rod 31251 is fixedly installed on one side of the filter plate 3125. A sliding groove 31252 and a rotating groove 31253 are provided on the fixing rod 31251. A slider 31221 is slidably connected to the sliding groove 31252. A rotating rod 31255 is slidably connected to the fixing rod 31251. The rotating rod 31255 is fixedly connected to the connecting rod 3122. The slider 31221 is fixedly connected to the connecting rod 3122. The slider 31221 is fixedly connected to the rotating rod 31255.

[0051] When the adjusting plate 3121 moves upward, it drives the slider 31221 to slide inside the sliding groove 31252 of the fixing rod 31251 through the connecting rod 3122, so that the slider 31221 moves to the rotating groove 31253. At this time, when the adjusting plate 3121 drives the connecting rod 3122 to rotate, the slider 31221 rotates in the rotating groove 31253 and does not drive the filter plate 3125 to rotate, thereby ensuring that the position of the liquid inlet 31254 does not move and guaranteeing the water inlet effect. In addition, when the connecting rod 3122 moves, through the limit between the slider 31221, the sliding groove 31252, the rotating rod 31255, and the fixing rod 31251, the stability of the connecting rod 3122 during movement is ensured, and shaking is avoided.

[0052] As a further extension of the present application, since there may be impurities on the surface of the sewage and there will be suspended solids in the sewage, if the sampling is directly carried out through the sampling bottle 3124, the sampling result may be deviated. Therefore, the present application sets a stirring assembly 32 to stir the sewage before sampling to ensure uniform sampling. The stirring assembly 32 includes: a measuring rod 321 fixedly installed on the sampling pipe 31, a sliding cavity 3211 opened on the measuring rod 321, a float 3212 slidably connected to the sliding cavity 3211, a stirring blade 323 threadedly connected to the measuring rod 321, and a spring 322 fixedly installed on the stirring blade 323; the spring 322 is fixedly installed on the sampling pipe 31. A limiting groove 3231 is opened on the stirring blade 323, and a positioning rod 31256 is slidably connected to the limiting groove 3231. Scale lines are opened on the measuring rod 321. The measuring rod 321 is divided into a connecting part and an identification part. Connecting part: Threads are provided for connecting with the stirring blade 323. Identification part: It is transparently arranged and scale lines are opened on the surface. A positioning rod 31256 is fixedly connected to the other side of the filter plate 3125.

[0053] When the filter plate 3125 moves downward, the positioning rod 31256 enters the inside of the limit groove 3231. At the same time, the positioning rod 31256 presses the stirring blade 323, causing the stirring blade 323 to rotate through the threaded part, so as to stir the suspended substances on the water surface and in the sewage, ensuring uniform sampling. In addition, when the positioning rod 31256 pushes the stirring blade 323 to rotate, the stirring blade 323 rotates and moves downward. At this time, the spring 322 is deformed by force. When the positioning rod 31256 does not press the stirring blade 323, the reset of the spring 322 can drive the stirring blade 323 to reset. In addition, it should be noted that when the positioning rod 31256 pushes the stirring blade 323 to rotate, the positioning rod 31256 rotates inside the limit groove 3231, so as to limit the stirring blade 323 and prevent the stirring blade 323 from shaking. In addition, the float 3212 moves in the sliding cavity 3211 as the height of the water surface changes. The height of the sewage can be known through the position of the float 3212 and the scale line.

The special-shaped parts can be customized according to the description in the specification and the drawings.
