AI Technical Summary
Existing water treatment water samplers are prone to causing the upper water layer to mix with the lower water layer during the lifting process, and surface floating objects can also intrude into the sample, causing contamination.
The negative pressure suction structure is adopted. Through the cooperation of the piston plate and the pin, the first spring pushes the piston plate to move down to generate negative pressure, which prevents the upper water body from mixing with the lower water sample and prevents surface floating objects from entering the sample.
This effectively prevents the upper water layer from mixing with the lower water sample, avoids surface floating matter from contaminating the water sample, and ensures that the collected water sample is pure and uncontaminated.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment sampling technology, and specifically discloses a water sample collector for water treatment. Background Technology
[0002] Water treatment is the process of altering the properties of water through physical, chemical, or biological means. A sampler is a device specifically designed to obtain representative liquid samples from a specific water body. Its core mission is to capture the physicochemical properties of the target water layer / body with minimal disturbance, providing undistorted raw samples for water quality analysis.
[0003] Existing water treatment water samplers are mostly designed with an open top. During the lifting process, the lower water sample is forcibly mixed with the upper water body (turbulent mixing effect). At the same time, surface floating matter (oil film, algae) can invade the sample and cause pollution to the collected water sample. Utility Model Content
[0004] This invention proposes a water sampler for water treatment. Through a negative pressure extraction structure, it can prevent the upper water body from mixing with the lower water sample and also prevent surface floating objects from entering the sample, thus avoiding pollution of the collected water sample.

[0006] The extraction mechanism includes a piston plate slidably connected inside the sampling cylinder. The upper end face of the sampling cylinder is connected to an annular receiving groove. A first spring is fixedly connected between the annular receiving groove and the piston plate. A water inlet hole is opened through the upper end face of the sampling cylinder.

An arc-shaped annular groove is opened on the outer wall of the pin. One side wall of each of the two inclined blocks extends into the arc-shaped annular groove.
[0007] In a preferred embodiment of the water treatment water sample collector of this utility model, the upper end face of the annular receiving trough is fixedly connected to a pull rope by multiple connecting ropes, the upper end of the pin extends to the top of the extension column and is fixedly connected to an inner rope, the upper end of the inner rope passes through the pull rope, and the inner rope and the pull rope are slidably connected.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0022] Please see Figure 1-4 A water treatment water sampler includes a sampling cylinder 1 with an open structure at the lower end, and an extraction mechanism is provided inside the sampling cylinder 1.
[0023] The extraction mechanism includes a piston plate 2 slidably connected inside the sampling cylinder 1. The upper end face of the sampling cylinder 1 is connected to an annular receiving groove 3. A first spring 4 is fixedly connected between the annular receiving groove 3 and the piston plate 2. A water inlet hole 5 is opened through the upper end face of the sampling cylinder 1. An extension column 6 extending through the water inlet hole 5 to the top of the sampling cylinder 1 is fixedly connected to the upper end face of the piston plate 2. A groove 7 is opened on the upper end face of the extension column 6. A notch 8 communicating with the groove 7 is opened through the outer wall of the extension column 6. Two symmetrically distributed inclined blocks 9 are slidably connected inside the notch 8. A pin 10 is set inside the groove 7. The lower end of the pin 10 is set as a conical structure matching the two inclined blocks 9 and extends to the bottom of the two inclined blocks 9. An arc-shaped annular groove 11 is opened on the outer wall of the pin 10. One side wall of the two inclined blocks 9 extends into the interior of the arc-shaped annular groove 11.
[0024] In this embodiment: Before use, insert your hand into the sampling cylinder 1 from the lower end and push the piston plate 2 to the upper end of the sampling cylinder 1. At this time, the piston plate 2 compresses the first spring 4 and retracts into the annular receiving groove 3. The piston plate 2 drives the extension column 6 to move through the water inlet 5 to the top of the sampling cylinder 1. Then, insert the pin 10 into the groove 7. Since the lower end of the pin 10 is set as a conical structure that matches the two inclined blocks 9, when the pin 10 moves downward, the conical structure can push the two inclined blocks 9. The face blocks 9 move in opposite directions, causing the two inclined face blocks 9 to move out of the notch 8 until the pin 10 moves downward until the arc-shaped groove 11 is flush with the two inclined face blocks 9, and the two inclined face blocks 9 enter the arc-shaped groove 11. Through the mutual matching between the arc-shaped groove 11 and the two inclined face blocks 9, the pin 10 can be limited, preventing the pin 10 from being thrown out of the groove 7 due to inertia. Then, the two inclined face blocks 9 and the extension column 6 limit the piston plate 2, fixing the piston plate 2 inside the upper part of the sampling cylinder 1. Figure 2 As shown;
[0025] In use, the sampling cylinder 1 is lowered into the water by pulling the rope 13. Water enters the sampling cylinder 1 through its lower end, facilitating its underwater movement. Simultaneously, the counterweight 19 accelerates the descent of the sampling cylinder 1. The descent depth is measured by measuring lines on the outer wall of the rope 13. Once the sampling cylinder 1 has reached the desired position, the inner rope 14 is pulled, causing the pin 10 to move out of the groove 7. During this process, the pin 10... The arc surface of the arc-shaped annular groove 11 forces the two inclined blocks 9 to disengage from the groove. Then, the two inclined blocks 9 move in opposite directions, entering the notch 8. This releases the limiting effect of the two inclined blocks 9 and the extension column 6 on the piston plate 2. The first spring 4 then rebounds, pushing the piston plate 2 towards the lower end of the sampling cylinder 1, creating a negative pressure inside. This negative pressure draws water from a suitable location through the water inlet 5 into the sampling cylinder 1. Figure 4 As shown, the sampling tube 1 is then pulled out of the water by the pull rope 13. The negative pressure extraction structure prevents the upper water from mixing with the lower water sample, prevents surface floating objects from entering the sample, and avoids contamination of the collected water sample.
[0026] As a technical optimization of this utility model, the upper end face of the annular storage groove 3 is fixedly connected to a pull rope 13 by multiple connecting ropes 12. The upper end of the pin 10 extends to the top of the extension column 6 and is fixedly connected to an inner rope 14. The upper end of the inner rope 14 passes through the pull rope 13, and the inner rope 14 and the pull rope 13 are slidably connected.
[0027] In this embodiment: the sampling cylinder 1 can be pulled by multiple connecting ropes 12 and pull ropes 13, and the pin 10 can be moved by the inner rope 14.
[0028] As a technical optimization of this utility model, a plurality of evenly distributed slide rods 15 are fixedly connected to the upper inner end of the sampling cylinder 1 and are slidably connected to the piston plate 2. The lower ends of the plurality of slide rods 15 extend to the lower inner end of the sampling cylinder 1 and are fixedly connected to a stop block.
[0029] In this embodiment: the piston plate 2 can be limited by multiple sliding rods 15 to make the piston plate 2 move smoothly, and the piston plate 2 can be limited by the stop block to prevent the piston plate 2 from moving out of the sampling cylinder 1.
[0030] As a technical optimization of this utility model, the front and rear inner sidewalls of the notch 8 are provided with grooves 16, and the front and rear end faces of the two inclined blocks 9 are fixedly connected with sliders 17 that match the two grooves 16 respectively. The left and right sidewalls of the two grooves 16 and the multiple sliders 17 are fixedly connected with second springs 18.
[0031] In this embodiment: the two inclined blocks 9 can be limited by multiple sliders 17 and multiple slide grooves 16, so that the two inclined blocks 9 can move smoothly. The two inclined blocks 9 can be pushed to move in opposite directions by multiple second springs 18 and multiple sliders 17.
[0032] As a technical optimization of this utility model, a counterweight 19 is fixedly connected to the lower end of the outer wall of the sampling cylinder 1.
[0033] In this embodiment, the sinking speed of the sampling cylinder 1 can be accelerated by using the counterweight 19.
[0034] As a technical optimization of this utility model, the sampling cylinder 1 is made of transparent tempered glass.
[0035] In this embodiment, the sampling tube 1 is made of transparent tempered glass, which facilitates observation of the inside of the sampling tube 1.
[0036] As a technical optimization of this utility model, the outer wall of the pull rope 13 is provided with measuring lines.
[0037] In this embodiment, the outer wall of the pull rope 13 is provided with measuring lines, which can be used to measure the sinking depth of the sampling cylinder 1.
[0038] The working principle and usage process of this utility model are as follows: During use, the sampling cylinder 1 is placed in water by pulling the rope 13. At this time, water enters the sampling cylinder 1 through its lower end, facilitating its downward movement. Simultaneously, the counterweight 19 accelerates the sinking speed of the sampling cylinder 1. The sinking depth of the sampling cylinder 1 is measured by the measuring lines on the outer wall of the rope 13. After the sampling cylinder 1 has moved to the appropriate position, the inner rope 14 is pulled, causing the pin 10 to move out of the groove 7. During the removal process, the arc surface of the arc-shaped groove 11 presses against the two inclined blocks. 9 disengages from the arc-shaped groove 11, and then is pushed by multiple second springs 18 and multiple sliders 17 to move the two inclined blocks 9 in opposite directions, so that the two inclined blocks 9 enter the notch 8, thereby releasing the limiting state of the two inclined blocks 9 and the extension column 6 on the piston plate 2. Then the first spring 4 rebounds and pushes the piston plate 2 to move to the lower end of the sampling cylinder 1, so that negative pressure is generated in the sampling cylinder 1. The negative pressure draws water from the appropriate position into the sampling cylinder 1 through the water inlet 5. Then the sampling cylinder 1 is pulled out of the water by the pull rope 13, thereby completing the water sampling operation.
