Description

Technical Field

[0001] This invention relates to the field of water environment testing equipment technology, and more specifically, to a water quality stratification sampler for water environment monitoring. Background Technology

[0002] The main function of a water stratification sampler is to distribute the collected water samples into different containers for subsequent water quality analysis and monitoring. It typically samples according to different water levels, stratifying the water to detect the quality of water at different heights. The stratification sampler usually has graduations to facilitate observation of the water level.

[0003] However, the sampling inlet is fixed. When performing stratified sampling, the sampling inlet cannot be adjusted according to the actual water level. As a result, if the water level is too low, the water flow will only pass through the bottom sampling inlet. If the water level is too high, it will be difficult to sample water close to the surface. Consequently, it is not easy to adjust the sampling inlet according to the required sampling height. Furthermore, if the water flow is too rapid, the impact force of the water is large. During sampling, the water is prone to backflow out of the sampler due to the inertia of the impact force. At the same time, if the impact force is too large, the water is prone to move up and down along the inner wall and flow into the sampling collection tanks at different water levels, which can easily affect the sampling collection effect.

The force plate is embedded in the side of the vertical plate, the flow hole is located inside the vertical plate, the vertical plate baffle plate is engaged inside the water inlet pipe, the force plate is inclined at 25 degrees and is a plate structure made of aluminum alloy, which has the characteristics of strong toughness and easy bending under force, and is distributed in a uniform ring-shaped state.

[0009] As a further improvement of the present invention, the locking plate is provided with a rubber rod, a triangular block, a second spring, and a sealing plate.

Beneficial effects

[0010] 1. In this invention, the arc-shaped plate slides and adjusts inside the flow tube via a sliding plate. At the same time, the position of the arc-shaped plate is fixed by the locking structure. After the water inlet follows the movement of the arc-shaped plate, the water inlet at its original position is blocked by the arc-shaped plate, making the middle of the water inlet the only water inlet for sampling. Under the obstruction of the force plate, the water is diverted, and the impact force of the water is blocked and dispersed, so that it passes horizontally and slowly through the flow hole in the vertical plate, preventing the water impact force from being too large.

[0011] 2. In this invention, when the tension tube moves up and down following the displacement of the inlet pipe, the right end of the tension tube moves up and down, and the left end of the tension tube tilts and pulls the flow plate. Under the obstruction of the two flow plates, the water flow becomes gentle. At the same time, water at the same water level will not flow to the water level on the upper and lower sides due to the obstruction of the gap plate, thus preventing the water from flowing up and down due to excessive flow force during water collection, and avoiding water flowing to other height sampling ports under impact force.

[0012] 3. In this invention, the arc-shaped plate is manually pushed, allowing it to slide and adjust inside the flow pipe via a sliding plate. This allows the arc-shaped plate to move up and down to adjust its height. During height adjustment, the connecting plate in the limiting structure slides and displaces along with the arc-shaped plate. This displacement causes the right side of the triangular block in the connecting block to be squeezed by the moving connecting plate, causing the triangular block to bend around the rubber rod as the center. This creates a blocking force to fix the position after height adjustment. By adjusting the height of the water inlet pipe, the sampling height can be adjusted according to the required water level.

Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings: Example

[0022] As attached Figure 1 To be continued Figure 5 As shown: This invention discloses a water quality stratified sampler for water environment monitoring. Its structure includes a guide tube 1, a sampling structure 2, a support rod 3, a conical block 4, a scale line 5, and a collection tube 6. The support rod 3 is fixed to the upper end of the sampling structure 2, the scale line 5 is attached to the outer surface of the sampling structure 2, the guide tube 1 is connected to the side of the sampling structure 2, the conical block 4 is engaged with the lower end of the guide tube 1, and the collection tube 6 is connected to the guide tube 1. The sampling structure 2 is provided with a limiting structure 21, a flow tube 22, a baffle plate 23, an arc-shaped plate 24, a water inlet pipe 25, and a sliding plate 26. The limiting structure 21 is fixed to the inner side of the arc-shaped plate 24, the sliding plate 26 is installed on the inner side of the arc-shaped plate 24, the water inlet pipe 25 is fixed to the outer side of the arc-shaped plate 24, the baffle plate 23 is engaged inside the water inlet pipe 25, the limiting structure 21 is installed on the outer side of the flow tube 22, and the flow tube 22 and the sliding plate 26 are slidably engaged. The tube 1 is connected to the left side of the flow tube 22. The support rod 3 is embedded in the upper end of the flow tube 22. The scale line 5 is attached to the outer surface of the flow tube 22. The outer side of the sliding plate 26 is provided with three balls, which have the effect of limiting the sliding. The support rod 3 is engaged with the left end of the support rod 3 by a ball, which has the effect of keeping the sampling structure 2 vertical. Thus, by holding the support rod 3, the height of the water inlet tube 25 can be adjusted by the arc plate 24, so that the arc plate 24 slides and adjusts inside the flow tube 22 through the sliding plate 26. At the same time, the position of the arc plate 24 is fixed under the engagement of the limiting structure 21. After the water inlet tube 25 moves with the arc plate 24, the water inlet at the original position is blocked by the arc plate 24, so that the middle of the water inlet tube 25 becomes the only water inlet for sampling. Then, the water is blocked and diverted by the blocking plate 23, reducing its impact force. Then, the water flows into the guide tube 1 in the flow tube 22 and is collected inside the collection tube 6.

[0023] The flow tube 22 includes a gap plate w1, a flow plate w2, a sealing tube w3, a stretching tube w4, and a limiting plate w5. The gap plate w1 is embedded inside the sealing tube w3, the stretching tube w4 is embedded on the side of the flow plate w2, the flow plate w2 is installed inside the sealing tube w3, the limiting plate w5 is embedded in the middle of the left side of the sealing tube w3, the stretching tube w4 is connected and embedded to the blocking plate 23, and the side of the sealing tube w3 is slidably engaged with the sliding plate 26. There are two flow plates w2, and the right flow plate w2 has a sliding track, which drives the flow plate w2 to slide up and down. The stretching tube w4 is made of rubber and has tensile deformation. Due to the characteristics of the water inlet pipe 25, the tension tube w4 moves up and down along with the water inlet pipe 25, causing the right end of the tension tube w4 to move up and down. This causes the left end of the tension tube w4 to tilt and pull the flow plate w2, which then slides up and down along the sliding track. As a result, water flows from the tension tube w4 onto the flow plate w2. The flow is smoothed by the obstruction of the two flow plates w2. At the same time, water at the same water level will not flow to the upper or lower water levels due to the obstruction of the gap plate w1. When the sealing tube w3 is filled with water, it enters the guide tube 1 on the left side through the limiting plate w5 under water pressure, thus preventing water from flowing up and down due to excessive flow force during collection.

[0024] The limiting plate w5 includes a fan-shaped plate w51, a circular rod w52, and a movable rod w53. The movable rod w53 is attached to the inner side of the t52, the fan-shaped plate w51 is embedded in the inner side of the movable rod w53, and the circular rod w52 is embedded in the middle of the left side of the tension tube w4. The movable rod w53 is made of rubber and has the characteristic of deformation and movement. The fan-shaped plate w51 is made of magnet and has the characteristic of opposite poles attracting each other. Thus, under water pressure, the fan-shaped plate w51 is pushed, and through the deformation and movement of the movable rod w53, the fan-shaped plate w51 bends and moves to open and close.

[0025] The baffle plate 23 includes a vertical plate t1, a flow hole t2, and a force-bearing plate t3. The force-bearing plate t3 is embedded in the side of the vertical plate t1, and the flow hole t2 is located inside the vertical plate t1. The vertical plate t1 and the baffle plate 23 are engaged inside the water inlet pipe 25. The force-bearing plate t3 is inclined at 25 degrees and is a plate-shaped structure made of aluminum alloy, which has the characteristics of high toughness and easy bending under force. It is distributed in a uniform ring shape, so that when the water first enters the water inlet pipe 25, it impacts on the inclined force-bearing plate t3. Under the obstruction of the force-bearing plate t3, the water is diverted, so that the impact force of the water is blocked and dispersed, and then it passes horizontally and slowly through the flow hole t2 in the vertical plate t1, preventing the water impact force from being too large. The specific usage and function of this embodiment are as follows: In this invention, the handrail 3 is used to adjust the height of the water inlet pipe 25 via the arc plate 24. The arc plate 24 slides and adjusts inside the flow pipe 22 via the sliding plate 26. At the same time, the position of the arc plate 24 is fixed by the locking structure 21. After the water inlet pipe 25 moves with the arc plate 24, the original water inlet is blocked by the arc plate 24, making the middle of the water inlet pipe 25 the only water inlet for sampling. Then, the water is blocked and diverted by the blocking plate 23. When the water first enters the water inlet pipe 25, it impacts the inclined force plate t3. Under the obstruction of the force plate t3, the water is diverted, and the impact force of the water is blocked and dispersed. Then, it passes horizontally and slowly through the flow hole t2 in the vertical plate t1, preventing the water impact force from being too large.

[0026] In this invention, when the tension tube w4 moves with the water inlet pipe 25 to adjust its height, the right end of the tension tube w4 moves up and down, and the left end of the tension tube w4 tilts and pulls the flow plate w2. Under the sliding track, the flow plate w2 slides up and down, and water enters from the tension tube w4 and flows onto the flow plate w2. The water flow becomes gentle under the obstruction of the two flow plates w2. At the same time, water at the same water level will not flow to the upper and lower water levels due to the obstruction of the gap plate w1. When the sealing tube w3 is filled with water, it pushes the fan-shaped plate w51 under water pressure. Through the deformation of the movable rod w53, the fan-shaped plate w51 bends and opens and closes, and water enters the guide tube 1 on the left side through the limiting plate w5. This prevents the water from flowing up and down due to excessive flow force during collection and avoids water flowing to other height sampling ports under impact force. Example

[0027] As attached Figure 6 To be continued Figure 7 As shown: The limiting structure 21 includes a connecting plate k1, a locking plate k2, a metal block k3, a connecting block k4, and a first spring k5. The locking plate k2 and the connecting block k4 are movably engaged, and the first spring k5 is slidably engaged with the side of the metal block k3. The locking plate k2 is installed on the outside of the metal block k3. The connecting plate k1 is embedded in the inside of the arc-shaped plate 24, and the metal block k3 is attached to the outside of the flow pipe 22. The first spring k5 is embedded in the inside of the arc-shaped plate 24 and is in a stretched state, exhibiting inward extension and retraction. The connecting block k4 has a triangular structure and is movably engaged with the locking plate k2. Thus, when the connecting plate k1 slides with the arc-shaped plate 24, the connecting block k4 and the locking plate k2 are movably engaged, thereby forming a blocking force. The first spring k5 slides inside the metal block k3, and under the elastic force of the first spring k5, the arc-shaped plate 24 maintains the effect of squeezing towards the flow pipe 22, preventing the generation of gaps.

[0028] The locking plate k2 includes a rubber rod k21, a triangular block k22, a second spring k23, and a sealing plate k24. The rubber rod k21 is attached to the lower end of the triangular block k22, the second spring k23 is embedded in the lower end of the triangular block k22, and the sealing plate k24 is locked to the lower end of the triangular block k22. The second spring k23 is installed on the outside of the metal block k3. The triangular block k22 is movably engaged with the connecting block k4. There are two second springs k23, which are distributed in a parallel state. Thus, the right side of the triangular block k22 is compressed by the movement of the connecting plate k1, causing the left side of the triangular block k22 to compress towards the second spring k23. Consequently, the right side of the second spring k23 bends, causing the triangular block k22 to bend around the rubber rod k21. Without external force, the triangular block k22 blocks the connecting block k4 through the elastic force of the second spring k23. The specific usage and function of this embodiment are as follows: In this invention, the arc-shaped plate 24 is manually pushed, causing it to slide and adjust within the flow pipe 22 via the sliding plate 26. This allows the arc-shaped plate 24 to move up and down to adjust its height. During height adjustment, the connecting plate k1 in the limiting structure 21 slides and displaces along with the arc-shaped plate 24. This displacement causes the right side of the triangular block k22 in the connecting block k4 to be compressed by the connecting plate k1, compressing the left side of the triangular block k22 towards the second spring k23. Consequently, the second spring k23 on the right side bends, causing the triangular block k22 to bend around the rubber rod k21. Without external force, the triangular block k22 blocks the connecting block k4 through the elastic force of the second spring k23, thus forming a blocking force to fix the position after height adjustment. The first spring k5 slides within the metal block k3, and under the elastic force of the first spring k5, the arc-shaped plate 24 maintains the effect of pressing towards the flow pipe 22, preventing gaps. By adjusting the height of the water inlet pipe 25, the sampling height can be adjusted according to the required water level. Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
