DETAILED DESCRIPTION

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 11As shown, the present invention is a sampling device for detecting antibiotics in sewage, comprising: a detection device 1, a sampling mechanism 3 for sampling sewage, and a mounting frame 2. The mounting frame 2 is fixedly mounted on the detection device 1. When in use, the mounting frame 2 is fixed to the detection position by screws to prevent the device from shaking during sampling and detection and affecting the sampling and detection results. Then, the sewage is sampled by the sampling mechanism 3 and sent to the detection device 1 for detection. The detection device 1 is a professional aquatic product antibiotic detector to ensure the detection effect of sewage.

[0024] The sampling mechanism 3 includes: a sampling tube 31, a sampling bottle 3124 for storing the sampling results, a plurality of sampling bottles 3124 are provided so as to isolate each sampling result to avoid interference between multiple sampling results and affect the detection result, an adjusting component 312 for adjusting the position of the sampling bottle 3124, a power source 311 for driving the adjusting component 312 to move along the axial direction of 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 enters the sewage for sampling, the power source 311 is preferably an electric telescopic rod, and in addition, the power source 311 can also drive multiple groups of sampling bottles 3124 to switch when driving the sampling bottle 3124 to move under the action of the adjusting component 312, thereby realizing switching different sampling bottles 3124 to perform multiple samplings of the same sewage at different depths, so as to ensure the diversity of the sampling results, so as to more accurately reflect the antibiotic residues in the sewage.

[0025] Specifically, the adjustment assembly 312 includes: an adjustment plate 3121, the adjustment plate 3121 is fixedly mounted on the output end of the power source 311, a guide block 31212 is fixedly mounted on the adjustment plate 3121; the guide block 31212 is slidably connected to the guide groove 3126, a connecting rod 3122 fixedly mounted on the adjustment plate 3121, a fixing member 3123 fixedly mounted on the connecting rod 3122, a filter plate 3125 for filtering impurities in sewage, a filter hole 31257 is provided on the other side of the filter plate 3125, 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 groove, the guide groove 3126 is a straight groove, and a plurality of straight grooves are provided on the sampling tube 31, and the arc grooves connect two adjacent groups of straight grooves (such as Figure 5 , Fig.11 as shown).

[0026] 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.

[0027] 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.

[0028] It should be supplemented that the sampling bottle 3124 can be detachably mounted on the fixing part 3123, and the fixing part 3123 is a plastic card, which is convenient for disassembling the sampling bottle 3124. A mounting plate 3111 is fixedly mounted on the power source 311, and a push rod 3112 is fixedly mounted on the mounting plate 3111. The mounting plate 3111 is fixedly mounted on the inner wall of the sampling tube 31. The sampling tube 31 is connected with a drain pipe 3113, and the drain pipe 3113 is connected to the detection device 1. The sampling tube 31 is fixedly mounted on the detection device 1. The sampling bottle 3124 is opened. A liquid outlet 31241 is provided, and a positioning hole 31211 is opened on the adjustment 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 adjustment plate 3121 corresponds to the position of the push rod 3112. At this time, the power source 311 continues to pull the adjustment plate 3121 upward, so that the push rod 3112 passes through the positioning hole 31211 and squeezes the sampling bottle 3124, and the water sample in the sampling bottle 3124 is discharged from the liquid outlet 31241 to the discharge pipe 3113, and finally transported to the inside of the detection device 1 for detection.

[0029] That is to say, when the power source 311 pulls the sampling bottle 3124 to adjust its position, on the one hand, it can drive the sampling bottle 3124 that has not been sampled to move with the sampling bottle 3124 that has completed sampling, and on the other hand, it can discharge the water sample in the sampling bottle 3124 after sampling for testing, which has a good use effect. The mounting plate 3111 can provide a stable connection between the power source 311 and the sampling tube 31 to ensure that the power source 311 does not shake when in use, and on the other hand, it can install the top rod 3112, which has good practicality.

[0030] As a further extension of the present application, an opening is provided at the end of the sampling bottle 3124 near the top rod 3112, and a push plate is slidably connected to the opening to ensure that when the sampling bottle 3124 moves up and contacts the top rod 3112, the top rod 3112 pushes the push plate to discharge the liquid in the sampling bottle 3124, thereby ensuring that the water can stably enter the interior of the detection device 1 for detection, and distance sensors are installed on the push plate and the other end of the sampling bottle 3124 to sense the amount of water in the sampling bottle 3124 in real time. In addition, a filter is provided at the liquid outlet 31241. When the water in the sampling bottle 3124 is discharged, it will be filtered again through the filter to ensure that no impurities in the water enter the detection device 1, thereby avoiding pipeline blockage that affects the circulation of water and the detection of the detection device 1.

[0031] The advantage of doing this is that, on the one hand, the water is double-filtered by the filter plate 3125 and the filter screen to ensure that no impurities in the water are input into the detection device 1 to affect the detection results. On the other hand, the impurities are filtered in the sampling bottle 3124. When the water in the sampling bottle 3124 is completely discharged, the distance between the two sets of distance sensors on the other end of the plate and the sampling bottle 3124 is the impurity content in the water. In this way, the impurity content in the sewage can be detected, and the detection effect of the sewage is good.

[0032] That is to say, when the power source 311 pulls the adjustment plate 3121 upward, on the one hand, the push rod 3112 can push the water inside the sampling bottle 3124 out and transport it to the detection device 1 for detection. On the other hand, the impurity content filtered in the sampling bottle 3124 can be detected, which has a good detection effect on sewage.

[0033] In addition, in order 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 provided on the guide groove 3126, and a push block 31262 is slidably connected to the inclined groove 31261, and an elastic block 31263 is fixedly connected to the push block 31262, and one end of the elastic block 31263 abuts against the inclined groove 31261. An elastic rope is also fixedly installed on the push block 31262, and one end of the elastic rope 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, and 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 the guide block 31212 pushes the push block 31262 in the inclined groove 31261 when moving downward. 261 moves inside, at this time the elastic rope is deformed by force, and under the influence of the inclined surface of the inclined groove 31261, the push block 31262 gradually enters the inclined groove 31261, so that the guide block 31212 contacts the chamfered surface on the push block 31262, and under the guidance of the chamfered surface, the push block 31262 is squeezed to make the elastic block 31263 contract, and at this time the guide block 31212 can move down normally, and then the elastic block 31263 resets to drive the push block 31262 to reset, and the elastic rope resets to pull the push block 31262 to move up, so that when the guide block 31212 moves up from the guide groove 3126, under the obstruction of the push block 31262, the guide block 31212 stably enters the inside of the adjusting groove 3127, thereby 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.

[0034] It should be added that the end face of the inclined groove 31261 close to the detection device 1 is the X face, and the side face abutting the elastic block 31263 is the Y face. One end of the elastic rope is fixedly connected to the X face, 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 face.

[0035] When the adjusting plate 3121 rotates, the connecting rod 3122 and the sampling bottle 3124 are driven to rotate. Since the filter plate 3125 is provided with a liquid inlet 31254, and only one group of liquid inlet 31254 is provided, if the filter plate 3125 rotates with the adjusting plate 3121, the liquid inlet 31254 will move accordingly, making it impossible for other groups of sampling bottles 3124 to be sampled. Therefore, a fixed rod 31251 is fixedly installed on one side of the filter plate 3125, and a slide groove 31252 and a rotating groove 31253 are provided on the fixed rod 31251. A slider 31221 is slidably connected to the slide groove 31252, and a rotating rod 31255 is slidably connected to the fixed 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, and the slider 31221 is fixedly connected to the rotating rod 31255.

[0036] When the adjusting plate 3121 moves upward, the connecting rod 3122 drives the slider 31221 to slide inside the slide groove 31252 on the fixed rod 31251, 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 will not drive the filter plate 3125 to rotate, thereby preventing the position of the liquid inlet 31254 from moving, thereby ensuring the water inlet effect. In addition, when the connecting rod 3122 moves, it passes through the limiters among the slider 31221, the slide groove 31252, the rotating rod 31255, and the fixed rod 31251 to ensure the stability of the connecting rod 3122 when moving and avoid shaking.

[0037] As a further extension of the present application, since there may be impurities on the surface of the sewage and there may be suspended matter in the sewage, if sampling is performed directly through the sampling bottle 3124, it may cause deviations in the sampling results. Therefore, the present application sets a stirring component 32 to stir the sewage before sampling to ensure uniform sampling. The stirring component 32 includes: a measuring rod 321 fixedly mounted on the sampling tube 31, a sliding cavity 3211 opened on the measuring rod 321, a float 3212 slidably connected to the sliding cavity 3211, and a threaded connection to the measuring rod. The stirring blade 323 on 321 is fixedly mounted on the spring 322 on the stirring blade 323; the spring 322 is fixedly mounted on the sampling tube 31, the stirring blade 323 is provided with a limiting groove 3231, and a positioning rod 31256 is slidably connected to the limiting groove 3231. The measuring rod 321 is provided with scale lines. The measuring rod 321 is divided into a connecting part and an identification part. The connecting part: a thread is provided for connecting with the stirring blade 323, and the identification part: a transparent surface is provided with scale lines. The other side of the filter plate 3125 is fixedly connected with the positioning rod 31256.

[0038] When the filter plate 3125 moves downward, the positioning rod 31256 enters the limiting groove 3231, and at the same time, the positioning rod 31256 squeezes the stirring blade 323, causing the stirring blade 323 to rotate through the threaded portion, thereby stirring the suspended matter on the water surface and the sewage to ensure uniform sampling. In addition, when the positioning rod 31256 pushes the stirring blade 323 to rotate, the stirring blade 323 moves downward while rotating. At this time, the spring 322 is deformed under force. When the positioning rod 31256 does not squeeze the stirring blade 323, the spring 322 is reset to drive the stirring blade 323 to reset. It should be noted that when the positioning rod 31256 pushes the stirring blade 323 to rotate, the positioning rod 31256 rotates inside the limiting groove 3231, thereby limiting the stirring blade 323 to prevent the stirring blade 323 from shaking. In addition, the float 3212 moves in the sliding cavity 3211 as the water surface height changes. The sewage height can be known through the position and scale line of the float 3212.
