Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a multi-layer water quality sampler. Background Art

[0002] Water quality monitoring is the continuous or periodic assessment of the quality of a water body to determine whether it meets specific water quality standards or regulations. This includes measuring and analyzing various physical, chemical and biological indicators in water bodies, such as pH, dissolved oxygen, nutrients, toxic substances, microorganisms, etc. The purpose of water quality monitoring is to protect human health, maintain ecological balance, and ensure the sustainable use of water resources. Water sampling is an important part of water quality monitoring, which involves collecting water samples from a specific place and time for analysis in the laboratory.

[0003] In water quality monitoring, water quality sampling is an important task, and water quality samplers are usually used to sample water bodies. Most of the water quality samplers in the prior art are bottle-type, consisting of a water sampling container, a water pipe, a depth measuring rope, etc. The bottle-type sampler places a narrow-mouthed glass bottle with a volume of 200 to 300 ml in a metal frame, with a weighted lead block at the bottom, and the frame and the bottle stopper are tied with ropes and thin ropes with depth marks respectively. When sampling, place the sampler to the specified depth, roll up the thin rope, open the bottle stopper, and allow the water sample to enter the bottle. However, this water quality sampler can only perform single-layer sampling of water bodies, and cannot sample water bodies of different layers at the same time. It is impossible to obtain water quality data at different depths of water bodies at the same time, and there are limitations in the study of the vertical distribution characteristics of water bodies. Utility Model Content

[0004] In view of the existing deficiencies, the utility model provides a multi-layer water quality sampler, which solves the problem that the water quality sampler in the prior art can only sample a single layer of water and cannot sample water bodies of different layers at the same time, has great limitations and low sampling efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A multi-layer water quality sampler comprises a stainless steel tube, wherein handles are fixedly arranged on the left and right sides of the upper end of the stainless steel tube, a support rod is vertically arranged inside the stainless steel tube, and the support rod is rotatably connected to the stainless steel tube, an adjustment knob is fixedly arranged on the top of the support rod, a plurality of groups of transparent collection cups are vertically arranged on the left side of the stainless steel tube ring surface, the transparent collection cups are fixedly connected to the stainless steel tube through an 8-shaped fixing bracket, and a cup cover is assembled at the upper opening of the transparent collection cup.

[0007] Furthermore, a measuring steel ruler is vertically fixed on the right side of the stainless steel tube ring surface, and the accuracy of the measuring steel ruler is centimeters.

[0008] Furthermore, a plurality of drainage holes are provided on both the front and rear sides of the stainless steel pipe ring surface.

[0009] Furthermore, the diameter of the cup cover is larger than the diameter of the transparent collection cup, a sealing rubber pad is provided at the contact point between the cup cover and the transparent collection cup, and the sealing rubber pad is fixedly adhered to the bottom surface of the cup cover.

[0010] Furthermore, a transverse connecting rod is fixed on the right side of the upper surface of the cup cover, the right end of the connecting rod extends into the stainless steel tube, the right end of the connecting rod passes through the support rod and is fixed by a nut, and an arc-shaped sliding groove is opened on the stainless steel tube at the connection with the connecting rod.

[0011] Furthermore, a notch is provided on the right side of the annular surface of the stainless steel tube, and the position of the notch corresponds to the position of the nut.

[0012] Furthermore, the handle annular cover is provided with an anti-slip cover made of rubber material.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The multi-layer water quality sampler of the utility model can drive the transparent collection cup to extend into the water body to sample it by setting a stainless steel tube. At the same time, by setting multiple groups of transparent collection cups at different positions, it can sample the water body at different depths at the same time, realizing the simultaneous sampling of water bodies at different layers, greatly improving the sampling efficiency and data comprehensiveness.

[0015] 2. The utility model provides an accurate depth reference for the operator through the measuring steel ruler, making water quality sampling more accurate and reliable. The operator can quickly determine the position where the transparent collection cup should be placed according to the water depth to be sampled by measuring the steel ruler. When it is necessary to sample water bodies of different depths in layers, the measuring steel ruler can help the operator clearly mark and record the depth corresponding to each collection cup, thereby ensuring that water samples at each layer can be accurately collected and analyzed.

[0016] 3. In the utility model, multiple sets of drainage holes are provided on both sides of the front and rear of the stainless steel tube ring surface. The multiple sets of drainage holes can maintain water flow balance during sampling. When the sampler is immersed in water, the drainage holes allow water to flow freely through the stainless steel tube, which helps to maintain the stability of the sampler in the water, reduce the resistance of the water flow to the sampler, ensure a smoother sampling process, and at the same time, the drainage holes facilitate the smooth discharge of water inside the stainless steel tube after sampling is completed.

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 6 As shown, a multi-layer water quality sampler includes a stainless steel tube 2, a handle 1 is fixedly provided on the left and right sides of the upper end of the stainless steel tube 2, a support rod 12 is vertically arranged inside the stainless steel tube 2, and the support rod 12 is rotatably connected to the stainless steel tube 2, an adjustment knob 6 is fixedly provided on the top of the support rod 12, and a plurality of groups of transparent collection cups 4 are vertically arranged on the left side of the ring surface of the stainless steel tube 2, the transparent collection cups 4 are fixedly connected to the stainless steel tube 2 through an 8-shaped fixed bracket 8, and a cup cover 7 is assembled at the upper opening of the transparent collection cup 4. This design solves the problem that the original water quality sampler can only perform single-layer sampling of water bodies, cannot sample water bodies of different layers at the same time, has large limitations, and has low sampling efficiency.

[0027] A measuring steel ruler 3 is fixed vertically on the right side of the annular surface of the stainless steel tube 2, and the accuracy of the measuring steel ruler 3 is centimeters. The measuring steel ruler 3 provides an accurate depth reference for the operator, making water quality sampling more accurate and reliable. The operator can quickly determine the position where the transparent collection cup 4 should be placed by measuring the steel ruler 3 according to the water depth to be sampled. When it is necessary to perform stratified sampling of water bodies of different depths, the measuring steel ruler 3 can help the operator clearly mark and record the depth corresponding to each collection cup, thereby ensuring that water samples at each level can be accurately collected and analyzed.

[0028] A plurality of drainage holes 5 are provided on both sides of the front and rear of the annular surface of the stainless steel tube 2. The plurality of drainage holes 5 can maintain the balance of water flow during sampling. When the sampler is immersed in water, the drainage holes 5 allow water to flow freely through the stainless steel tube 2, which helps to maintain the stability of the sampler in the water, and can reduce the resistance of the water flow to the sampler, ensuring a smoother sampling process. At the same time, the drainage holes 5 facilitate the smooth discharge of water inside the stainless steel tube 2 after the sampling is completed.

[0029] The diameter of the cup cover 7 is larger than that of the transparent collection cup 4. A sealing rubber pad 14 is provided at the contact point between the cup cover 7 and the transparent collection cup 4, and the sealing rubber pad 14 is fixedly adhered to the bottom surface of the cup cover 7. This design helps to firmly cover and protect the transparent collection cup 4 during the sampling process, preventing the water sample from overflowing or being invaded by external contaminants, and at the same time can ensure the sealing of the transparent collection cup 4 to prevent the water sample from leaking through the contact surface.

[0030] A transverse connecting rod 9 is fixed on the right side of the upper surface of the cup cover 7, and the right end of the connecting rod 9 extends into the interior of the stainless steel tube 2. The right end of the connecting rod 9 passes through the support rod 12 and is fixed by a nut 13. An arc-shaped slide groove 10 is provided at the connection between the stainless steel tube 2 and the connecting rod 9. The cup cover 7 is connected to the support rod 12 by the connecting rod 9, which ensures the stability of the cup cover 7, and at the same time enables the cup cover 7 to rotate with the rotation of the support rod 12, which is convenient for controlling the opening and closing of the cup cover 7 and improves the convenience of water sampling.

[0031] A notch 11 is provided on the right side of the annular surface of the stainless steel tube 2 , and the position of the notch 11 corresponds to the position of the nut 13 . This design facilitates the installation of the nut 13 on the support rod 12 through the provided notch 11 , thereby facilitating the assembly of the support rod 12 .

[0032] The annular cover of the handle 1 is provided with an anti-slip cover made of rubber material. The rubber material has good anti-slip properties, especially in a humid or slippery environment. When the operator is taking water samples, the anti-slip cover can ensure that the handle 1 is always firmly held in the hand, reducing the risk of operating errors or equipment falling due to hand slippage.

[0033] The working principle of the multi-layer water quality sampler is as follows: when sampling a water body, first hold the handle 1, then extend the stainless steel tube 2 together with the transparent collection cup 4 into the water body, and by observing the position of the water surface on the measuring steel ruler 3, the depth position of each transparent collection cup 4 in the water body can be accurately understood. After the transparent collection cup 4 is placed at the required depth in the water body, the adjusting knob 6 is turned counterclockwise, and the support rod 12 is driven to rotate by the adjusting knob 6, and then the cup cover 7 is driven to rotate outward by the support rod 12, so that the cup cover 7 is opened, and then water flows into the transparent collection cup 4. In this process, by observing the escape of water bubbles on the water surface, it can be understood whether the water sample in the transparent collection cup 4 is full. After the transparent collection cup 4 is full, the adjusting knob 6 is turned in the opposite direction to close the cup cover 7, and the transparent collection cup 4 is sealed by the cup cover 7, and then the stainless steel tube 2 can be taken out of the water body.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
