Figure 1-9 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Reference Figure 1-Figure 4A water sample pretreatment device comprises a treatment pool 1, a partition 2, a filter 3, a power assembly 4 and a cutter head 5, wherein the treatment pool 1 is composed of a pool body 14 and a pool cover 13, the pool cover 13 is fixedly arranged on the pool body 14, the partition 2 and the filter 3 are vertically fixedly arranged in the pool body 14, the partition 2 is located below the filter 3 and is on the same vertical plane, and the top of the filter 3 is in contact with the bottom surface of the pool cover 13, thereby dividing the pool body 14 into a first cabin 11 and a second cabin 12. The filter 3 and the cutter head 5 are both made of stainless steel material, so that the filter 3 and the steel knife 5 have sufficient structural strength. A water inlet 111 and an overflow port 112 are formed on the side surface of the first cabin 11, wherein the overflow port 112 is located at the top of the side surface of the first cabin 11, so that the position height of the overflow port 112 is higher than the position height of the water inlet 111. In addition, a first water outlet 113 is formed at the bottom end of the first cabin 11, and a second water outlet 121 is formed at the bottom end of the second cabin 12. The water inlet 111, the overflow port 112, the first water outlet 113 and the second water outlet 121 are all controlled by electric valves to be in an open or closed state.

[0029] When the water sample pretreatment device is used to treat the water sample, the first water outlet 113 at the bottom of the first cabin 11 is closed, and the water sample is introduced into the first cabin 11 from the water inlet 111 on one side of the first cabin 11 until the liquid level in the first cabin 11 is the same height as the water inlet 111, and then the electric valve at the first water outlet 113 is opened to discharge the water sample in the first cabin 11, thereby rinsing the interior of the first cabin 11. Then, the electric valves at the first water outlet 113 and the second water outlet 121 are closed, and the water sample is introduced into the first cabin 11 from the first water inlet 111, so that the liquid level in the first cabin 11 gradually rises and overflows from the filter 3 into the second cabin 12. At the same time, the fine sand and gravel in the water sample are blocked by the filter screen 3 and retained in the first cabin 11, and the excess liquid in the first cabin 11 is discharged from the overflow port 112. When the water sample overflowing into the second cabin 12 reaches a certain liquid level, the electric valve at the second water outlet 121 is opened, so that the water sample in the second cabin 12 is discharged from the second water outlet 121, thereby completing the rinsing of the second cabin 12. At this time, the inner walls of the first cabin 11 and the second cabin 12 are the same water sample. Finally, the electric valve at the second water outlet 121 can be closed again, so that the liquid level in the second cabin 12 rises to complete the water storage.

[0030] Reference Figure 1 , Figure 5 and Figure 6The power assembly 4 includes an adjustable motor 41 and a motor bracket 42. The motor bracket 42 is arranged on the pool cover 13. The adjustable motor 41 is fixed on the motor bracket 42 by bolts. The shaft of the adjustable motor 41 is kept vertically downward. In order to install an extension shaft 43 on the shaft of the adjustable motor 41, a coupling 44 is arranged between the extension shaft 43 and the shaft of the adjustable motor 41, so that the extension shaft 43 and the shaft of the adjustable motor 41 are fixedly connected to the coupling 44 respectively, so that one end of the extension shaft 43 is inserted into the second cabin 12.

[0031] Reference Figure 5 , Figure 7 and Figure 8 The cutter head 5 includes a cutter rod 51, a first blade 52 and a second blade 53, wherein the first blade 52 and the second blade 53 are both composed of a connecting portion 521 and a cutting portion 522, the cutting portion 522 is located on both sides of the connecting portion 521 and is perpendicular to the connecting portion 521, the connecting portion 521 of the first blade 52 and the connecting portion 521 of the second blade 53 are fixedly connected and perpendicular to each other, and the cutting portion 522 of the first blade 52 and the cutting portion 522 of the second blade 53 are inclined in opposite directions, and the two ends of the cutter rod 51 are respectively fixed to the extension shaft 43 and the connecting portion 521 of the first blade 52. The cutter head 5 is fixedly connected to the extension shaft 43 so that the cutter head 5 is located on one side of the partition 2. When pre-processing the water sample entering the second cabin 12, the shaft of the adjustable motor 41 rotates, thereby driving the extension shaft 43 and the cutter head 5 to rotate. The cutter head 5 rotates at a high speed to break up small particles passing through the filter 3. After a certain period of time, the adjustable motor 41 is adjusted to a low speed to make the water sample in the second cabin 12 uniform.

[0032] After the water sample pretreatment device completes the pretreatment of the water sample, a plurality of sampling ports 122 are formed on the outer surface of the second cabin 12, and the plurality of sampling ports 122 are distributed along the vertical direction of the outer side of the second cabin 12, so that the water sample in the second cabin 12 can be detected from the sampling ports 122. After the water sample is processed by the water sample pretreatment device, a small amount of fine sand and gravel will be stuck in the mesh of the filter 3. In order to facilitate the cleaning of the fine sand and gravel stuck in the mesh, a cleaning port 123 is formed on the side of the second cabin 12 away from the filter 3. Water can be sprayed from the cleaning port 123 onto the filter 3 for cleaning, and the fine sand and gravel stuck in the mesh can be washed down by flushing the filter 3.

[0033] Reference Figure 1 and Fig. 9In order to facilitate the installation and fixation of the treatment pool 1, a mounting bracket 6 is fixedly arranged at the bottom of the treatment pool 1. The mounting bracket 6 includes a mounting plate 61, a fixing plate 62 and a connecting plate 63. One side of the mounting plate 61 is connected to one side of the fixing plate 62, and the mounting plate 61 and the fixing plate 62 are kept perpendicular to each other, and the two sides of the connecting plate 63 are respectively fixed to the mounting plate 61 and the fixing plate 62. The treatment pool 1 is fixedly installed on the mounting plate 61 by bolt locking, and the fixing plate 62 is fixedly installed on the wall by bolt locking.

[0034] The specific implementation principle of the embodiment of the present application is: when the water sample pretreatment device needs to be used, the first water outlet 113 at the bottom of the first cabin 11 is closed, and the water sample is introduced into the first cabin 11 from the water inlet 111 on one side of the first cabin 11 until the liquid level in the first cabin 11 is the same height as the water inlet 111, and then the electric valve at the first water outlet 113 is opened to discharge the water sample in the first cabin 11, thereby completing the rinsing of the interior of the first cabin 11.

[0035] Then close the electric valves at the first water outlet 113 and the second water outlet 121, and introduce the water sample into the first cabin 11 from the first water inlet 111, so that the liquid level in the first cabin 11 gradually rises and overflows from the filter 3 to the second cabin 12. At the same time, the fine sand and gravel in the water sample are blocked by the filter 3 and retained in the first cabin 11, and the excess liquid in the first cabin 11 is discharged from the overflow port 112. When the water sample overflowing into the second cabin 12 reaches a certain liquid level, open the electric valve at the second water outlet 121, so that the water sample in the second cabin 12 is discharged from the second water outlet 121, thereby completing the rinsing of the second cabin 12. At this time, the inner walls of the first cabin 11 and the second cabin 12 are the same water sample. Finally, the electric valve at the second water outlet 121 can be closed again, so that the liquid level in the second cabin 12 rises to complete the water storage.

[0036] The shaft of the adjustable motor 41 starts to rotate to drive the extension shaft 43 and the cutter head 5 to rotate. The cutter head 5 rotates at a high speed to break up the small particles after passing through the filter screen 3, so that the water sample in the second cabin 12 is evenly mixed, and the fine particles in the water sample are broken up to prevent the pipeline from being blocked. Finally, the stirred water sample is sampled and tested from the sampling port 122. After the water sample is pre-treated using the water sample pre-treatment device, a water pipe is used to spray water from the cleaning port 123 to the surface of the filter screen 3 for flushing, so as to wash down the fine sand and gravel stuck in the mesh.
