Description

Technical Field

[0001] The utility model belongs to the field of water quality monitoring, and more specifically, it relates to a water quality monitoring stratified sampling device. Background Art

[0002] Water quality monitoring stratified sampling devices are mainly used to collect water samples from water bodies at different depths in order to analyze the components and characteristics of water quality, and are widely used in rivers, lakes, groundwater, etc.

[0003] Since stratified sampling of water quality requires the device to be at different horizontal levels for extraction, it is difficult to know the presence of other impurities in the water during extraction, and it is easy to inhale them together during the pumping sampling, resulting in problems such as blockage. Summary of the Utility Model

[0004] In order to solve the above technical problems, the purpose and effect of a water quality monitoring stratified sampling device of the utility model are achieved by the following specific technical means:

[0005] Its structure includes a fixed head, a support rod, a moving group, a fixed block, a control end, a floating ring, a fixed cylinder, and a movable cylinder. The fixed head and the support rod are of an integrated structure. The moving group is connected to the movable cylinder and moves within the support rod. The fixed block is fixed between the fixed cylinder and the support rod. The control end is connected to the upper end of the fixed cylinder. The floating ring is sleeved on the outer surface of the fixed cylinder.

[0006] The movable cylinder includes a sampling cylinder, a moving rod, a limiting block, a control ring, a housing, and a suction pipe. The sampling cylinder is assembled inside the housing. The moving rod is connected to the control ring. The control ring is controlled by the control end. The suction pipe penetrates the housing and is connected to the sampling cylinder. The limiting block is located at the lower end of the moving rod for limiting. When the device moves to the required sampling depth, the floating ring uses its own buoyancy to assist the whole to be more stable in the water.

[0007] As a further improvement of the utility model, the sampling cylinder includes a middle cylinder, a sub-sampling cylinder, a connecting pipe, and a top cover. The sub-sampling cylinder is communicated with the middle cylinder through the connecting pipe. The top cover is installed above the middle cylinder. The sub-sampling cylinder further screens and stores the collected liquid separately.

[0008] As a further improvement of the utility model, the suction pipe includes a bent pipe, a delivery head, a push pipe, a convex block, a baffle, and an inner net. The bent pipe is communicated with the delivery head. The push pipe supports between the delivery head and the baffle. The convex block and the baffle are of an integrated structure. The inner net is installed on the outer end surface of the delivery head. The baffle has a certain inclination angle, which can make the impurities move along the trend and better slide to the convex block.

[0009] As a further improvement of the present utility model, the floating ring is made of floating material and has an annular structure. The movable cylinder can be adjusted by moving according to the required distance and depth. The fixed head is of a conical structure and is more stable when the whole needs to touch the bottom. The floating ring can maintain a certain buoyancy to fix the floating stability when the device is in water. The support rod drives the whole device to move to the required position and plays a role of fixing and limiting.

[0010] As a further improvement of the present utility model, six baffles are provided and are evenly distributed in a circle. The inner net is installed obliquely at a conical angle. The push tube itself has elasticity and can return to its original position in time after being stressed at the auxiliary connection part. There is a range drop in the movement between the convex block and the baffle, so that impurities can effectively push the baffle through the interception of the convex block.

[0011] As a further improvement of the present utility model, the moving rod drives the outer shell to move up and down along the limiting block. The limiting block is fixed on the inner surface of the fixed cylinder. The outer shell plays a role of protecting and waterproofing the internal parts.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. When the extraction tube extracts liquid, if impurities are sucked to the surface of the baffle by the water flow, the inclined angle of the baffle helps the impurities slide to the convex block. Through the flow direction of the water pumping, the impurities push the convex block through the water thrust, causing the baffle to squeeze and expand the push tube. When the baffle expands, the impurities hanging on the surface of the convex block will fall off through the inclined angle. A small part of the impurities are intercepted by the inner net. Through the inclined angle of the inner net, the impurities are helped to flow along the trend. When some small impurities enter the middle cylinder together, they will be sieved again before being sub-packed in the sub-sampling cylinder, avoiding mixing small impurities into the sub-sampling cylinder. It can intercept and guide the separation of impurities in the water while taking stratified samples, avoiding affecting the sampling of the liquid.

[0014] 2. When the device needs to touch the bottom for sampling, it can be fixed to the bottom through the fixed head to fixedly install the whole device, making the sampling cylinder more stable when pumping and sampling. If it does not need to touch the bottom and is in water, the floating ring will be used to float and control the overall stability. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] The following further describes the present utility model in conjunction with the attached drawings:

[0022] As shown in the attached Figure 1 to the attached Figure 5 figure:

[0023] The present utility model provides a water quality monitoring stratified sampling device, the structure of which includes a fixed head 1, a support rod 2, a moving group 3, a fixed block 4, a control end 5, a floating ring 6, a fixed cylinder 7, and a movable cylinder 8. The fixed head 1 and the support rod 2 are of an integrated structure. The moving group 3 is connected to the movable cylinder 8 and moves within the support rod 2. The fixed block 4 is fixed between the fixed cylinder 7 and the support rod 2. The control end 5 is connected to the upper end of the fixed cylinder 7. The floating ring 6 is sleeved on the outer surface of the fixed cylinder 7.

[0024] The movable cylinder 8 includes a sampling cylinder 81, a moving rod 82, a limit block 83, a control ring 84, an outer shell 85, and an extraction tube 86. The sampling cylinder 81 is assembled inside the outer shell 85. The moving rod 82 is connected to the control ring 84. The control ring 84 is controlled by the control end 5. The extraction tube 86 passes through the outer shell 85 and is connected to the sampling cylinder 81. The limit block 83 is located at the lower end of the moving rod 82 for limiting. When the floating ring 6 moves the device to the required sampling depth, its own buoyancy assists the whole to be more stable in the water. The movable cylinder 8 can slightly adjust its required depth according to its position.

[0025] Among them, the sampling cylinder 81 includes a middle cylinder 11, a sub - sampling cylinder 12, a connecting pipe 13, and a top cover 14. The sub - sampling cylinder 12 is communicated with the middle cylinder 11 through the connecting pipe 13. The top cover 14 is installed above the middle cylinder 11. The sub - sampling cylinder 12 further screens and stores the collected liquid separately. The extraction tube 86 is of an L - shaped structure, which can better sample on the required horizontal plane.

[0026] Among them, the extraction pipe 86 includes a curved pipe 61, a conveying head 62, a push pipe 63, a protrusion 64, a baffle 65, and an inner net 66. The curved pipe 61 is connected to the conveying head 62, and the push pipe 63 is supported between the conveying head 62 and the baffle 65. The protrusion 64 and the baffle 65 are an integrated structure. The inner net 66 is installed on the outer end surface of the conveying head 62. The baffle 65 has a certain inclination angle, which can allow impurities to move along with the trend and better slide to the protrusion 64. When the impurities continue to push the protrusion 64, the push pipe 63 will be forced to squeeze the swing baffle 65, thereby allowing the impurities to be smoothly separated.

[0027] Among them, the float ring 6 is made of floating material and has a circular ring structure. The movable cylinder 8 can be moved and adjusted according to the required distance and depth. The fixed head 1 is a conical structure and is more stable when the whole device needs to touch the bottom. The float ring 6 can maintain a certain buoyancy and fixed floating stability when the device is in the water. The support rod 2 drives the entire device to move to the required position and plays a role in fixed limiting. The control end 5 mainly receives signals to control the device to adjust and move.

[0028] Among them, there are six baffles 65 and they are evenly distributed in a circle. The inner net 66 is installed at an inclined angle at a conical angle. The push tube 63 itself is elastic, and the auxiliary connecting part returns to its position in time after being subjected to force. There is a difference in the moving range between the protrusion 64 and the baffle 65, so that impurities can be intercepted by the protrusion 64 and effectively push the baffle 65. The angle of the inner net 66 itself can guide some impurities to flow out in the inclined direction.

[0029] Among them, the moving rod 82 drives the shell 85 to move up and down along the limit block 83. The limit block 83 is fixed to the inner surface of the fixed cylinder 7. The shell 85 plays a protective and waterproof role for the internal parts. The sampling cylinder 81 is equipped with two for layered sampling.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In the present invention, the device is moved to the desired depth, and the buoyancy support is provided by the float ring 6 to stabilize the whole. If the sampling position of the movable cylinder 8 needs to be fine-tuned, the control ring 84 is controlled by the control end 5 to drive the moving rod 82 to move along the limit block 83, so that the movable cylinder 8 is adjusted and moved to the desired position along the moving group 3. The control end 5 controls the sampling cylinder 81 to extract the liquid on the horizontal surface through the extraction pipe 86. The liquid will enter the delivery head 62 through the inner net 66 and be delivered to the inside of the middle cylinder 11 by the bend pipe 61. When the extraction pipe 86 extracts the liquid, if there are impurities, they will be sucked away by the water flow. When the impurities are sucked onto the surface of the baffle 65, the inclined angle of the baffle 65 helps them slide to the protrusion 64. The water flow direction causes the impurities to push the protrusion 64 through the water thrust, causing the baffle 65 to squeeze and expand the push tube 63. When the baffle 65 expands, the impurities hanging on the surface of the protrusion 64 will fall off due to the inclined angle. A small amount of impurities will be intercepted by the inner net 66. The inclined angle of the inner net 66 helps the impurities flow smoothly. When some small impurities enter the interior of the middle tube 11, they will be screened before being packaged in the sample separation tube 12 to prevent them from mixing into the interior of the sample separation tube 12. While sampling in layers, impurities in the water can be intercepted and guided to separate, avoiding affecting the sampling of the liquid.

[0032] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
