Description

Technical Field

[0001] The invention relates to the field of sampling devices, in particular to a detection sampling device for production and preparation of drinking water. Background Art

[0002] Drinking water refers to water that can be directly supplied to the human body for drinking without treatment. Water is the main component of body fluids and an important substance that constitutes cells, tissue fluid, plasma, etc. Water is the medium for all chemical reactions in the body and is a platform for the transportation of various nutrients and substances.

[0003] In the prior art, a Chinese patent document with publication number CN118275170A proposes a device for detecting and sampling water pollution in paint production. The device solves the problem that the sampler generally samples a part of the water body in the area, resulting in the need for multiple samplings during sampling, making the overall sampling procedure more complicated and reducing the sampling efficiency. Improvements are needed to address this problem. However, in actual application, when drinking water production and preparation requires testing and sampling, in order to ensure the drinking safety of drinking water, the sampling interval is short, and staff are required to perform testing and sampling frequently. Moreover, since there is a certain time interval between two samplings, the sampling port needs to be cleaned before the next sampling, and the drinking water remaining in the sampling port during the last sampling time needs to be discharged. The operation steps are cumbersome, making the testing and sampling work take a long time, extending the staff's testing and sampling time, and delaying the staff's work progress. Therefore, we disclose a detection and sampling device for drinking water production and preparation to meet the needs of reducing the staff's work on drinking water testing and sampling speed and improving the staff's work progress on drinking water testing and sampling.

The lower ends of the limiting rods 31 form a circle, and the width of the tin foil 34 is greater than the diameter of the limiting rod 31.A blade is fixedly connected to the lower end of the limiting rod 31, allowing the limiting rod 31 to poke a circular tinfoil 34 in the middle of the tinfoil 34 without affecting the subsequent winding of the tinfoil 34. With the second sampling bottle 21 located at the lower end of the limiting rod 31, the tinfoil 34 can cover the upper end of the second sampling bottle 21. The first limiting frames 19 are evenly spaced in each group, ensuring that the first limiting frames 19 drive the first sampling bottle 13 and the second sampling bottle 21 to reach the set position after movement.

[0033] The working principle of the present invention is as follows: when in use, when the movable shell 8 is pushed upward by the force, the rack 9 is driven upward together, so that the rack 9 drives the first gear 10 to rotate, so that the first gear 10 drives the sealing plate 12 to turn ninety degrees through the rotating shaft 11, so that the drinking water flowing from the production water pipe 4 to the sampling water pipe 5 can flow in the sampling water pipe 5, so that the drinking water is discharged from the sampling water pipe 5, and the first sampling bottle 13 and the second sampling bottle 21 are respectively taken over by the first sampling bottle 13 and the second sampling bottle 21. The residual drinking water from the last sampling and the newly discharged drinking water in the sampling water pipe 5 are ensured, and the accuracy of the drinking water detection sampling is ensured, and the working operation steps are saved and the working efficiency is improved. When the conveyor belt 1 moves, the first sampling bottle 13 and the second sampling bottle 21 are driven to move, so that the staff can place the first sampling bottle 13 and the second sampling bottle 21 in advance according to the position of each group of first limiting racks 19, avoiding the first sampling bottle 13 and the second The sampling bottle 21 is placed incorrectly, and the interval between the first sampling bottle 13 and the second sampling bottle 21 is fixed to ensure the normal progress of the next step. When sampling is needed, the first motor 2 is started to drive the conveyor belt 1 to move, and automatic detection and sampling of drinking water can be carried out to save manpower. A timer can also be installed on the first motor 2 and the length of the conveyor belt 1 can be extended to place multiple groups of first sampling bottles 13 and second sampling bottles 21, so that drinking water detection and sampling can be carried out when the staff is not on site. After the first sampling bottle 13 or the second sampling bottle 21 reaches the lower end of the sampling water pipe 5, the movement of the conveyor belt 1 is stopped, and then the telescopic cylinder 20 lifts the first sampling bottle 13 or the second sampling bottle 21 upward and connects it to the sampling water pipe 5, and then lifts the movable shell 8 upward, so that the drinking water in the sampling water pipe 5 flows into the first sampling bottle 13 or the second sampling bottle 21, completing the detection and sampling of drinking water.

[0034] The outer wall of the sampling water pipe 5 is cleaned by the cleaning block 18, so that the second gear 15 can drive the cleaning block 18 to rotate through the rotating frame 14, thereby improving the cleaning effect of the cleaning block 18 on the sampling water pipe 5. After the first sampling bottle 13 pushes the movable shell 8 to the upper end, the third gear 16 is engaged with the second gear 15, so that after the second motor 17 is started, the second gear 15 is driven to rotate through the third gear 16, so that the cleaning block 18 rotates and rubs the outer wall of the sampling water pipe 5, so that the first sampling bottle 13 can clean the outer wall of the sampling water pipe 5 when it is filled with discarded drinking water for testing, saving the operation time of drinking water testing and sampling, and improving the drinking water testing and sampling time, thereby improving work efficiency.

[0035] The fourth motor 24 drives the second bevel gear 27 to rotate through the first bevel gear 26, so that the second bevel gear 27 drives the connecting plate 30 to move up and down through the fourth belt group 28 and the screw sleeve group 29. When the second bevel gear 27 rotates, the reel 33 is driven to rotate, so that the reel 33 drives the elastic rope 32 to move, and when the limit rod 31 moves downward, the tinfoil 34 is punctured, so that the middle part of the tinfoil 34 forms a circular cover on the upper end of the second sampling bottle 21, and then the limit rod 31 covers the punctured tinfoil 34 to the upper end of the second sampling bottle 21. The top of the second sampling bottle 21 is covered to prevent dust from falling into the second sampling bottle 21 during placement and affecting the accuracy of detection during citation. The second sampling bottle 21 can also be temporarily placed at the sampling point after sampling to avoid the situation where the staff fails to take away the sampled drinking water in time, which causes the sampling of drinking water to be unavailable. After the limit rod 31 returns to its original position, the third motor 23 is started to drive the tinfoil 34 to rotate through the third belt group 25, so that the punctured position of the tinfoil 34 is rolled up, and a new section of tinfoil 34 is pulled out for next use.

[0036] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
