Description

Technical Field

[0001] The present application relates to the technical field of surface water quality monitoring, and in particular to a surface water sampling device. Background Art

[0002] With the rapid development of social economy and the continuous advancement of urbanization, the problem of surface water environmental pollution has become increasingly prominent, and the treatment of water environmental pollution has become the key work of current environmental protection in China.

[0003] For the treatment of water environmental pollution, it is necessary to first use a sampler to sample surface water, then detect the surface water sample, and carry out targeted treatment work according to the detection results. According to the requirements of the "Technical Specification for Surface Water Environment Quality Monitoring", when the water depth is between 0.5 m and 5 m (0.5 m < h ≤ 5 m), the vertical sampling point of surface water is at 0.5 m below the water surface.

[0004] Existing samplers usually tie a rope to the sampling cylinder, and then use manual labor or tools to immerse the sampling cylinder into the water to a specified depth, and then extract the sampling cylinder from the water, that is, the sampling work of surface water is completed. For example, a Chinese patent with the patent number CN202220113652.6 and the name of a hydrogeological groundwater depth sampler, and a Chinese patent with the patent number CN201721142261.2 and the name of an environmental assessment surface water sampler. However, in actual application in flowing water bodies, after the sampling cylinder is immersed in the water, it will be affected by the water flow direction, and the rope often cannot achieve a good fixing effect on the sampling cylinder. Therefore, the sampling cylinder will flow downstream with the water body for a certain distance. During this process, it is difficult to control the depth of the sampling cylinder in the water, and errors are likely to occur, and it is impossible to accurately sample the surface water at the specified depth sampling point. Utility Model Content

[0005] In order to improve the defects existing in the above-mentioned prior art, the present application provides a surface water sampling device.

[0006] A surface water sampling device provided by the present application adopts the following technical solutions:

[0007] A surface water sampling device includes:

[0008] A sampling inlet pipe, one end of the sampling inlet pipe is provided with a sampling water inlet, and the other end of the sampling inlet pipe is connected to a vacuum water pump;

[0009] A vertical fixing arm, a fixing component is arranged between the sampling inlet pipe and the vertical fixing arm. While fixing the sampling inlet pipe on the vertical fixing arm, the fixing component also enables the sampling inlet pipe to be adjusted in position in the length direction of the vertical fixing arm;

[0010] A water surface floater, a connecting component is arranged between the vertical line fixing arm and the water surface floater, and the vertical line fixing arm is fixed on the water surface floater through the connecting component.

[0011] By adopting the above technical solution, under the action of the water surface floater, it is ensured that the vertical line fixing arm and the sampling water inlet pipe do not sink in the water during the surface water sampling process, and during actual implementation, it only requires the sampling personnel to control the water surface floater so as not to be washed away by the water flow. The vertical line fixing arm ensures that the sampling water inlet pipe is always in the direction of the vertical line in the water and will not be affected by the water flow direction. Therefore, the depth of the sampling water inlet of the sampling water inlet pipe in the water can be accurately controlled, that is, the position of the surface water vertical line sampling point can be accurately controlled. Thus, the surface water at the specified depth sampling point can be accurately sampled. And because the sampling water inlet pipe can be adjusted in position in the length direction of the vertical line fixing arm, the surface water sampling device of the present application can flexibly adjust the depth of the surface water vertical line sampling point according to actual sampling needs, so as to sample the surface water at any depth. During actual sampling work, the sampling personnel only need to turn on the vacuum water pump to achieve the purpose of surface water sampling, and turn off the vacuum water pump after the surface water sampling is completed.

[0012] Optionally, the sampling water inlet pipe is a sampling water inlet pipe made of rubber material, and the vertical line fixing arm is a vertical line fixing arm made of space aluminum material.

[0013] By adopting the above technical solution, the sampling water inlet pipe made of rubber material is more flexible, convenient and lightweight to use, and the vertical line fixing arm made of space aluminum material is lighter and has higher strength. Above all, both the sampling water inlet pipe made of rubber material and the vertical line fixing arm made of space aluminum material have the advantage of being lightweight, so they will not generate a large load pressure on the water surface floater.

[0014] Optionally, a plurality of fixing components are arranged in the length direction of the vertical line fixing arm. The fixing component includes a fixing hoop, a tie strap and a connecting rod connecting the fixing hoop and the tie strap. The fixing hoop is sleeved on the vertical line fixing arm and the inner circle of the fixing hoop is adapted to the outer wall of the vertical line fixing arm. A fastening member is arranged between the fixing hoop and the vertical line fixing arm for fixing the fixing hoop on the vertical line fixing arm. The tie straps on each connecting rod bind and fix the sampling water inlet pipe.

[0015] By adopting the above technical solution, the fixing component can firmly fix the sampling water inlet pipe on the vertical line fixing arm, and if the position of the sampling water inlet pipe is adjusted, only the positions of the respective fixing hoops on the vertical line fixing arm need to be adjusted accordingly.

[0016] Optionally, a sliding block is provided on the inner wall of the fixed hoop, and a sliding groove is formed along the length direction on the outer wall of the vertical line fixing arm. The sliding block is slidably arranged in the sliding groove. A plurality of fastening holes are spaced apart on the groove wall of the sliding groove. A through hole is formed in the sliding block and the fixed hoop together, and the through hole can correspond to any one of the fastening holes. The fastener is arranged in the through hole and the fastening hole to fix the fixed hoop on the vertical line fixing arm.

[0017] By adopting the above technical solution, the arrangement of the sliding block and the sliding groove ensures the stability of the sliding of the fixed hoop on the vertical line fixing arm, so that the fixed hoop will not rotate and affect the fixing effect on the sampling inlet pipe. Moreover, the number of fastening holes in the sliding groove is relatively large, and it can be flexibly fixed at multiple places in cooperation with the through hole and the fastener to better meet the needs of the use of the sampling inlet pipe.

[0018] Optionally, a flared pipe orifice is provided at the sampling inlet of the sampling inlet pipe.

[0019] By adopting the above technical solution, the flared pipe orifice is provided to facilitate the sampling of surface water by the sampling inlet pipe.

[0020] Optionally, a filter screen is provided in the flared pipe orifice. The flared pipe orifice is sleeved at the sampling inlet of the sampling inlet pipe, and the flared pipe orifice and the sampling inlet pipe are fixed by screws.

[0021] By adopting the above technical solution, a filter screen is provided in the flared pipe orifice to effectively filter out impurities in the water to avoid blockage caused by impurities entering the sampling inlet pipe. Secondly, the flared pipe orifice and the sampling inlet pipe are detachable so that the flared pipe orifice can be removed in time for cleaning after the filter screen is blocked.

[0022] Optionally, the water surface floating device is set as a rubber airbag with a hollow middle part, and the connecting component is arranged at the hollow middle part of the rubber airbag to fix the vertical line fixing arm.

[0023] By adopting the above technical solution, under the action of the water surface floating device which is a rubber airbag, it is ensured that the vertical line fixing arm and the sampling inlet pipe do not sink in the water during the surface water sampling process, and in actual implementation, it only requires the sampling personnel to control the water surface floating device not to be washed away by the water flow.

[0024] Optionally, the connecting component includes a space aluminum plate arranged at the hollow middle part of the rubber airbag. The vertical line fixing arm and the space aluminum plate are welded and fixed, and a notch for the sampling inlet pipe to pass through is formed on the space aluminum plate.

[0025] By adopting the above technical solution, the space aluminum plate, as a connecting component, fixes the vertical line fixing arm on the rubber airbag. Both the space aluminum plate and the vertical line fixing arm are made of space aluminum, which has high strength, is lightweight, has good performance, and will not exert a large load pressure on the rubber airbag.

[0026] In summary, the present application includes the following beneficial technical effects:

[0027] 1. Under the action of the water surface floating device, it is ensured that the vertical line fixing arm and the sampling inlet pipe do not sink in the water during the surface water sampling process, and in actual implementation, the sampling personnel only need to control the water surface floating device so that it is not washed away by the water flow.

[0028] 2. The vertical line fixing arm ensures that the sampling inlet pipe is always in the direction of the vertical line in the water and will not be affected by the water flow direction. Therefore, the depth of the sampling inlet of the sampling inlet pipe in the water can be accurately controlled, that is, the position of the surface water vertical sampling point can be accurately controlled. Thus, the surface water at the specified depth sampling point can be accurately sampled. And since the sampling inlet pipe can be adjusted in position in the length direction of the vertical line fixing arm, the surface water sampling device of the present application can flexibly adjust the depth of the surface water vertical sampling point according to the actual sampling needs, so as to sample the surface water at any depth. During the actual sampling work, the sampling personnel only need to turn on the vacuum water pump to achieve the purpose of surface water sampling, and turn off the vacuum water pump after the surface water sampling is completed.

Detailed implementation manners

[0035] The following further elaborates on this application Figures 1-4 in conjunction with the accompanying drawings.

[0036] An embodiment of this application discloses a surface water sampling device. Referring to Figure 1 and Figure 2 , the surface water sampling device includes a water surface floater 4, a vertical line fixing arm 2, and a sampling water inlet pipe 1. The water surface floater 4 is a rubber airbag with a circular hole reserved in the middle, similar to the structure of a swimming ring. It floats on the water surface to ensure that the vertical line fixing arm 2 and the sampling water inlet pipe 1 do not sink in the water during the surface water sampling process. And in actual implementation, it only requires the sampling personnel to control the water surface floater 4 not to be washed away by the water flow. The vertical line fixing arm 2 is fixed on the water surface floater 4 by means of a connecting component 5, and the connecting component 5 is arranged in the circular hole reserved in the middle of the rubber airbag. The connecting component 5 is a circular space aluminum plate 51. The space aluminum plate 51 is adhesively fixed to the rubber airbag, and the bottom surface of the space aluminum plate 51 is flush with the lower edge of the rubber airbag, so as to facilitate calculating the sinking depth of the sampling water inlet pipe 1 starting from the water surface. The vertical line fixing arm 2 is welded and fixed to the space aluminum plate 51, and both the vertical line fixing arm 2 and the space aluminum plate 51 are made of space aluminum material, with high strength, light weight, good performance, and will not exert a large load pressure on the rubber airbag. In addition, a notch 511 is opened on one side of the space aluminum plate 51 for the sampling water inlet pipe 1 to pass through.

[0037] Referring to Figure 1 and Figure 2 , the sampling water inlet pipe 1 is made of rubber. After passing through the notch 511 of the space aluminum plate 51, the sampling water inlet pipe 1 is arranged along the length direction of the vertical line fixing arm 2. The end of the sampling water inlet pipe 1 entering the water is set as the sampling water inlet, and a flared pipe orifice 7 is arranged on the sampling water inlet. The other end of the sampling water inlet pipe 1 is connected to a vacuum water pump (not shown in the drawings). In actual sampling work, the sampling personnel only need to turn on the vacuum water pump to achieve the purpose of surface water sampling, and turn off the vacuum water pump after the surface water sampling is completed. The rubber sampling water inlet pipe 1 is fixed to the space aluminum vertical line fixing arm 2 by a plurality of fixing components 3. While the fixing components 3 can fix the sampling water inlet pipe 1, they can also enable the sampling water inlet pipe 1 to be adjusted in position along the length direction of the vertical line fixing arm 2, that is, to adjust the sinking depth of the sampling water inlet pipe 1 in the water, so as to flexibly sample surface water at any depth.

[0038] When actually sampling surface water, the sampling personnel need to adjust the length of the sampling inlet pipe 1 extending downward from the space aluminum plate 51 according to the depth of the sampling point. In this application, taking the water depth between 0.5 m and 5 m (0.5 m < h ≤ 5 m) as an example, and the surface water vertical sampling point is 0.5 m below the water surface, it is necessary to adjust the length from the inlet end of the trumpet-shaped nozzle 7 to the bottom surface of the space aluminum plate 51 (equivalent to the water surface) to be 0.5 m. Then, use each fixing component 3 to fix the sampling inlet pipe 1 on the vertical fixing arm 2, and then lower the surface water sampling device into the water. During this process, under the fixing action of the vertical fixing arm 2, it can be ensured that the sampling inlet pipe 1 is always in a vertical state in the water and will not be affected by the water flow direction. Therefore, the depth of the sampling inlet pipe 1 lowered into the water can be accurately controlled, that is, the position of the surface water vertical sampling point can be accurately controlled, so as to accurately sample the surface water at the specified depth sampling point (0.5 m below the water surface).

[0039] Refer to Figure 1 , the fixing component 3 includes a fixing hoop body 31, a nylon tie 33, and a connecting rod 32 connecting the fixing hoop body 31 and the tie 33. The tie 33 is used to tie and fix the rubber sampling inlet pipe 1, and the fixing hoop body 31 is adaptively sleeved on the vertical fixing arm 2 and can slide on the vertical fixing arm 2 to achieve the purpose of position adjustment. For example, when the surface water vertical sampling point is deeper and the lowering length of the sampling inlet pipe 1 is longer, it is necessary to move each fixing hoop body 31 downward so that the distances between the fixing hoop bodies 31 are farther apart. If the surface water vertical sampling point is shallower and the lowering length of the sampling inlet pipe 1 is shorter, it is necessary to move each fixing hoop body 31 upward so that the distances between the fixing hoop bodies 31 are closer. And in combination with Figure 3 and Figure 4 , specifically, a sliding block 311 is integrally provided on the inner circle of the fixing hoop body 31, and a sliding groove 21 for the sliding block 311 to slide is opened on the outer wall of the vertical fixing arm 2 along its length direction. In this way, the fixing hoop body 31 can slide stably on the vertical fixing arm 2 without rotating. A plurality of fastening holes 211 are equidistantly opened on the groove wall of the sliding groove 21 along the length direction of the sliding groove 21. The hole wall of the fastening hole 211 has threads, and a through hole 6 is opened on each sliding block 311. The through hole 6 penetrates the corresponding fixing hoop body 31. When the fixing hoop body 31 moves to the corresponding fastening hole 211, the through hole 6 on the fixing hoop body 31 corresponds to the fastening hole 211. At this time, the fixing hoop body 31 can be fixed on the vertical fixing arm 2 by using a fastener, that is, the fastener passes through the through hole 6 and then inserts into the fastening hole 211 and is threadedly connected with the fastening hole 211. The fastener can be a bolt.

[0040] Refer to Figure 1, in addition, it should also be noted that a filter screen 8 is provided at the water inlet end of the trumpet-shaped nozzle 7. The filter screen 8 is used to effectively filter out impurities in the water to prevent the impurities from entering the sampling inlet pipe 1 and causing blockage. Secondly, the trumpet-shaped nozzle 7 and the sampling inlet pipe 1 are of a detachable structure. Specifically, the trumpet-shaped nozzle 7 is sleeved at the sampling water inlet of the sampling inlet pipe 1, and the trumpet-shaped nozzle 7 and the sampling inlet pipe 1 are fixed by screws. The trumpet-shaped nozzle 7 and the sampling inlet pipe 1 are detachable so that the trumpet-shaped nozzle 7 can be removed in time for cleaning after the filter screen 8 is blocked.

[0041] The implementation principle of a surface water sampling device disclosed in an embodiment of the present application is as follows: Under the action of the water surface float 4, it is ensured that the vertical line fixing arm 2 and the sampling inlet pipe 1 do not sink in the water during the surface water sampling process, and in actual implementation, it only requires the sampling personnel to control the water surface float 4 not to be washed away by the water flow. The vertical line fixing arm 2 ensures that the sampling inlet pipe 1 is always in the direction of the vertical line in the water and will not be affected by the water flow direction. Therefore, the depth of the sampling water inlet of the sampling inlet pipe 1 in the water can be accurately controlled, that is, the position of the surface water vertical line sampling point can be accurately controlled. Thus, the surface water at the specified depth sampling point can be accurately sampled. And because the sampling inlet pipe 1 can be adjusted in position in the length direction of the vertical line fixing arm 2, the surface water sampling device of the present application can flexibly adjust the depth of the surface water vertical line sampling point according to actual sampling needs. Thus, the surface water at any depth can be sampled. During actual sampling work, the sampling personnel only need to turn on the vacuum water pump to achieve the purpose of surface water sampling, and turn off the vacuum water pump after the surface water sampling is completed.

[0042] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
