[0002] In surface water monitoring, water quality sampling is one of the essential tasks. In order to truly reflect the water pollution situation, representative water samples must be collected. When conducting sewage treatment research, it is necessary to sample sewage from multiple locations such as sewage pool inlet units and intermediate sewage treatment units.

[0003] For example, a sewage sampler with publication number CN221056124U that can quickly achieve solid-liquid separation includes: a sampler body, a conveying pipeline, a base, a cylinder, a storage and sedimentation part, a rotating separation part and a fine filtration output part; the cylinder is invertedly installed on the base, one end of the conveying pipeline is connected to the water outlet of the sampler body, and the other end of the conveying pipeline is connected to the cylinder from the top, the storage and sedimentation part is arranged in the cylinder, the rotating separation part is installed on the base and located in the cylinder, the fine filtration output part is arranged on the base, and the storage and sedimentation part is located between the conveying pipeline and the rotating separation part The sewage sampler that can quickly realize solid-liquid separation can continue to perform multiple processes of continuous separation on the sewage sample after the main body of the sampler completes the sampling of the sewage. The steps are quick and simple, and at the same time, it ensures that the solid-liquid separation can be completed quickly, reducing labor intensity and improving the efficiency of solid-liquid coordinated treatment. However, the device rotates and separates the sewage through the first side retaining net and the second side retaining net. During the rotation, large particles of impurities in the sewage may be stuck on the retaining net. After a long period of separation operation, the area of ​​the retaining net that is blocked increases, which is not convenient for the rapid separation of sewage, reduces the separation efficiency of sewage, and also brings trouble to subsequent cleaning, and there are certain defects.

[0028] A method for using a sewage sampling and collecting device with a pre-separation structure, the steps are as follows:

[0029] Step 1: Sampling sewage through the sampler, opening the valve on the connecting pipe, the sewage flows into the treatment cylinder through the connecting pipe, firstly adsorbed by the adsorption layer, which can be made of activated carbon, and then guided into the separation cylinder by the guide plate, the motor is started to rotate, the motor drives the rotating shaft and the main gear to rotate, the main gear drives the side gears on both sides to rotate, the side gear drives the lever to rotate, the blocking rod blocks the fixed rod, so that the lever drives the fixed rod to rotate clockwise, the fixed rod drives the main pulley to rotate, the main pulley drives the rotating shaft to rotate, and the main pulley drives the slave pulley to rotate through the toothed belt, the torsion spring is used to reset the rotating shaft and the main pulley, so that the main pulley is reset after rotating for a certain arc;

[0030] Step 2: Since the diameter of the slave pulley is much smaller than that of the main pulley, the slave pulley will rotate several times before resetting, and the slave pulley drives the screw to rotate, and the side block limits the adjusting sleeve, so that the adjusting sleeve rises when the slave pulley rotates, and the adjusting sleeve drives the connecting rod and the vertical rod to rise, and the vertical rod drives the top block and the cross bar to rise, and the cross bar drives the mounting ring and the scraper to rise. At this time, the top block blocks the guide plate, thereby realizing intermittent discharge of sewage and the scraper reciprocating up and down to scrape the inner wall of the separation cylinder, reducing the blockage of particles in the sewage, and improving the effect of sewage separation, so that the water body is separated into the water storage barrel. After a period of time, open the treatment barrel, connect the water pipe outside the water storage barrel with the outside to drain water, and obtain a sample of water body and solid separation;

[0031] Step 3: After the sampling is completed, place the sampler in the middle of the clamp and press down the sampler. The sampler will squeeze the clamp, and the clamp will drive the slider to slide on the guide rod. The slider compresses the spring until the bottom of the sampler contacts the bottom plate. The elastic force of the spring drives the slider to move, and the slider drives the clamp to clamp the lower part of the sampler, thereby facilitating the fixed placement of the sampler.

[0032] Compared with the prior art, the invention has the following beneficial effects: a separation assembly is provided to realize intermittent discharge of sewage and reciprocating up and down movement of the scraper to scrape the inner wall of the separation cylinder, thereby reducing the blockage of particles in the sewage, improving the effect of sewage separation, and facilitating the acquisition of samples separated from water and solids;

[0033] A separation component is provided, which is first adsorbed by an adsorption layer, which can be made of activated carbon, and then guided into the separation cylinder by a guide plate. The motor is started to rotate, and the main pulley rotates for a certain arc and then resets. The slave pulley rotates a few circles and then resets, which can drive the top block and the cross bar to rise. The cross bar drives the mounting ring and the scraper to rise. At this time, the top block blocks the guide plate, thereby realizing intermittent discharge of sewage and the scraper reciprocating up and down to scrape the inner wall of the separation cylinder, reducing the blockage of particles in the sewage, improving the effect of sewage separation, and separating the water into the water storage barrel. The problem of large particle impurities in the sewage during the rotation process may be stuck on the retaining net.

[0034] A positioning component is provided. After sampling is completed, the sampler is placed in the middle of the clamp block and the sampler is pressed down. The sampler will squeeze the clamp block, and the clamp block will drive the slider to slide on the guide rod. The slider compresses the spring until the bottom of the sampler contacts the bottom plate. The elastic force of the spring drives the slider to move, and the slider drives the clamp block to clamp the lower part of the sampler, thereby facilitating the fixed placement of the sampler and improving the convenience of use.

[0057] Embodiment 1: Figure 1-8 As shown, a separation component 7 is provided. When in use, the sewage is sampled through the sampler 5, and the valve on the connecting pipe 8 is opened. The sewage flows into the treatment cylinder 6 through the connecting pipe 8, and is first adsorbed by the adsorption layer 71. The adsorption layer 71 can be made of activated carbon, and then is guided into the separation cylinder 75 by the guide plate 72. The motor 73 is started to rotate, and the motor 73 drives the rotating shaft 76 and the main gear 77 to rotate. The main gear 77 drives the side gears 78 on both sides to rotate, and the side gears 78 drive the lever 79 to rotate. The blocking rod 715 blocks the fixed rod 714, so that the lever 79 drives the fixed rod 714 to rotate clockwise, and the fixed rod 714 drives the main pulley 712 to rotate, and the main pulley 712 drives the rotating shaft 711 to rotate, and the main pulley 712 drives the slave pulley 719 to rotate through the toothed belt 716. The torsion spring 713 is used to reset the rotating shaft 711 and the main pulley 712, so that the main pulley 712 is reset after rotating for a certain arc.

[0058] Since the diameter of the slave pulley 719 is much smaller than the main pulley 712, the slave pulley 719 will rotate several circles before resetting, and the slave pulley 719 drives the screw rod 718 to rotate, and the side block 722 limits the adjusting sleeve 720, so that the adjusting sleeve 720 rises when the slave pulley 719 rotates, and the adjusting sleeve 720 drives the connecting rod 723 and the vertical rod 724 to rise, and the vertical rod 724 drives the top block 725 and the cross bar 726 to rise, and the cross bar 726 drives the mounting ring 727 and the scraper 728 to rise.

After sampling is completed, the sampler 5 is placed in the middle of the clamping block 45, and the sampler 5 is pressed down. The sampler 5 will squeeze the clamping block 45, and the clamping block 45 drives the slider 43 to slide on the guide rod 42. The slider 43 compresses the spring 44 until the bottom of the sampler 5 contacts the bottom plate 1. The elastic force of the spring 44 drives the slider 43 to move, and the slider 43 drives the clamping block 45 to clamp the lower part of the sampler 5, thereby facilitating the fixed placement of the sampler 5 and improving the convenience of use.

[0063] Working principle: When using the device, first, Figure 1-10 As shown, the sewage is sampled through the sampler 5, the valve on the connecting pipe 8 is opened, and the sewage flows into the treatment cylinder 6 through the connecting pipe 8, and is first adsorbed by the adsorption layer 71. The adsorption layer 71 can be made of activated carbon, and then is guided into the separation cylinder 75 by the guide plate 72. The motor 73 is started to rotate, and the motor 73 drives the rotating shaft 76 and the main gear 77 to rotate. The main gear 77 drives the side gears 78 on both sides to rotate, and the side gears 78 drive the lever 79 to rotate. The blocking rod 715 blocks the fixed rod 714, so that the lever 79 drives the fixed rod 714 to rotate clockwise, and the fixed rod 714 drives the main pulley 712 to rotate, and the main pulley 712 drives the rotating shaft 711 to rotate, and the main pulley 712 drives the slave pulley 719 to rotate through the toothed belt 716. The torsion spring 713 is used to reset the rotating shaft 711 and the main pulley 712, so that the main pulley 712 is reset after rotating for a certain arc.

[0064] Since the diameter of the slave pulley 719 is much smaller than the main pulley 712, the slave pulley 719 will rotate several circles before resetting, and the slave pulley 719 drives the screw rod 718 to rotate, and the side block 722 limits the adjusting sleeve 720, so that the adjusting sleeve 720 rises when the slave pulley 719 rotates, and the adjusting sleeve 720 drives the connecting rod 723 and the vertical rod 724 to rise, and the vertical rod 724 drives the top block 725 and the cross bar 726 to rise, and the cross bar 726 drives the mounting ring 727 and the scraper 728 to rise. At this time, the top block 725 blocks the guide plate 72, thereby realizing the intermittent discharge of sewage and the reciprocating up and down movement of the scraper 728 to scrape the inner wall of the separation cylinder 75, reducing the blockage of particles in the sewage, improving the sewage separation effect, and separating the water into the water storage barrel 74. After a period of time, open the treatment barrel 6, and connect the water pipe outside the water storage barrel 74 to the outside to drain water, so as to obtain a sample of water and solid separation.

[0065] After sampling is completed, the sampler 5 is placed in the middle of the clamp 45, and the sampler 5 is pressed down. The sampler 5 will squeeze the clamp 45, and the clamp 45 will drive the slider 43 to slide on the guide rod 42. The slider 43 compresses the spring 44 until the bottom of the sampler 5 contacts the bottom plate 1. The elastic force of the spring 44 drives the slider 43 to move, and the slider 43 drives the clamp 45 to clamp the lower part of the sampler 5, thereby facilitating the fixed placement of the sampler 5.
