Description

Technical Field

[0001] This utility model relates to the field of water quality testing and sampling technology, specifically a water quality testing and sampling device for different water depths. Background Technology

[0002] Water quality testing sampling devices for different water depths refer to equipment specifically designed to collect water samples from water bodies at different depths. These devices can ensure that representative samples are obtained from the surface to the deep water. Common sampling devices include surface samplers, deep samplers, and automatic samplers. Surface samplers are usually used to collect water samples near the water surface, while deep samplers are equipped with extension mechanisms to reach specific depths for sampling. There are also water samplers such as the Vandal water sampler and gravity water sampler, which can collect water samples at different depths based on the density changes of different water layers. These sampling devices are crucial for monitoring parameters such as vertical water quality distribution, temperature, dissolved oxygen, and nutrient concentration in water bodies, and are indispensable tools for water quality monitoring and hydrological research. Existing non-electronic water quality sampling devices have relatively large data errors in sampling depth because the distance between the riverbank and the water surface makes it difficult to observe the scale. Therefore, a water quality sampling device for different water depths is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a water quality testing and sampling device for different water depths, in order to solve the problem that existing non-electronic water quality testing and sampling devices, when sampling water samples at riverbank locations, make it difficult to observe the scale due to the distance between the riverbank and the water surface, resulting in relatively large data errors in the sampling depth.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figure 1-5 This utility model provides a technical solution: A water quality sampling device for different water depths includes a handle 1, a pole 2, and a central hole 3. The pole 2 is welded and fixed to the bottom of the handle 1. The central hole 3 is opened inside the pole 2. A sampling bottle 7 is fixedly connected to the inner side of the bottom of the pole 2. A plug 8 is provided on one side of the lower end of the sampling bottle 7. The upper end of the sampling bottle 7 is tightly attached to the sealing plate 11 through a comb-shaped sealing ring 13. The upper end of the sealing plate 11 is connected to the fixed ring plate 10 through a telescopic spring 6. A spiral plate 12 is fixedly connected to the middle of the lower end of the sealing plate 11. A pull rope 9 is fixedly connected to the middle of the upper end of the sealing plate 11. The top end of the pull rope 9 is connected to the positioning mechanism 4. The positioning mechanism 4 includes a buoyancy plate 41. A groove 43 is opened inside the buoyancy plate 41. A ball bearing 44 is rotatably connected inside the groove 43. A bracket 45 is fixedly connected to the middle of the upper end of the buoyancy plate 41. A take-up reel 42 is rotatably connected to the middle of the bracket 45 through a rotating shaft 47. A locking bolt 46 is spirally connected to the inner side of the lower end of the bracket 45.

[0017] As a further implementation of this solution, the handle 1 and the upright 2 are on the same axis. The outer side of the upright 2 is provided with scale lines 5, and the pull rope 9 is set inside the upright 2. This makes it convenient for staff to hold and operate the entire sampling device, providing a point of leverage for the sampling process. This allows staff to stably control the entry and exit of the upright 2 and the sampling components below it into the water, ensuring that the sampling is carried out smoothly. As a further implementation of this solution, the upper end of the telescopic spring 6 is fixedly connected to the fixed ring plate 10, the lower end of the telescopic spring 6 is fixedly connected to the sealing plate 11, the pull rope 9 is set inside the telescopic spring 6, the fixed ring plate 10 is fixedly connected to the inner wall of the center hole 3, and the pull rope 9 is set inside the fixed ring plate 10. The staff can remotely control the opening and closing of the sealing plate 11 by adjusting the take-up wheel 42 to pull the rope 9, so as to realize automatic sampling at a specific depth and avoid manual direct contact with the sampling bottle 7. It is especially suitable for deeper waters or complex sampling environments. As a further implementation of this solution, the comb-shaped sealing ring 13 is fixedly connected to the upper end of the sampling bottle 7. The included angle between the spiral plate 12 and the sealing plate 11 is 90°. The spiral plate 12 is set inside the sampling bottle 7 and fits tightly against the upper end of the sampling bottle 7. It cooperates with the sealing plate 11 to form a reliable sealing structure. When water enters the sampling bottle 7, it effectively prevents external water from entering the upper end of the sampling bottle 7 unexpectedly, ensuring the purity of the collected water sample and avoiding the mixing of external impurities that may affect the water quality test results. After sampling, it can also prevent the collected water sample from seeping out. As a further implementation of this scheme, the buoyancy plate 41 has two internal grooves 43, and several ball bearings 44 are rotatably connected inside the grooves 43. The buoyancy plate 41 is slidably connected to the upright 2 through the grooves 43. Utilizing the buoyancy characteristics, it automatically floats on the water surface during sampling, providing a reference for the entire sampling depth positioning. By cooperating with the grooves 43 and ball bearings 44 of the upright 2, it can slide flexibly on the upright 2 to adapt to water surface fluctuations and ensure the relative accuracy of the sampling depth. Especially when there is a distance between the riverbank and the water surface and it is not easy to observe the scale line 5, the sampling depth can be set in advance according to the position of the buoyancy plate 41 to achieve precise sampling. As a further implementation of this scheme, the top of the pull rope 9 passes through the middle position of the buoyancy plate 41 and is wrapped around the outside of the take-up reel 42. The pull rope 9 is slidably connected to the middle position of the buoyancy plate 41. By rotating the take-up reel 42, excess pull rope 9 is collected, so that the initial relative position of the sealing plate 11 and the sampling bottle 7 meets the sampling requirements. As a further implementation of this solution, the rotating shaft 47 is fixedly connected inside the take-up reel 42. The rotating shaft 47 is rotatably connected to the bracket 45. The top of the locking bolt 46 is tightly attached to one side of the bottom of the take-up reel 42. After adjusting the position of the take-up reel 42, tighten the locking bolt 46 so that its top is tightly attached to one side of the bottom of the take-up reel 42. This can fix the take-up reel 42 and prevent the pull rope 9 from loosening or the sampling depth from changing due to accidental rotation during the sampling process. This ensures the stability of the preset sampling depth and guarantees the accuracy of the sampling results.

[0018] Workflow: When sampling water at different depths, the position of the buoyancy plate 41 can be adjusted according to the sampling needs. During the adjustment, the sampling depth is the same as the distance from the bottom of the buoyancy plate 41 to the top of the sampling bottle 7. After adjustment, the excess pull rope 9 is stored in the take-up reel 42. After storage, the locking bolt 46 is turned to position the take-up reel 42. After positioning, the staff inserts the sampling bottle 7 into the water using the upright 2. When the buoyancy plate 41 contacts the water surface and the pull rope 9 is pulled to control the sealing plate 11 to move upward, water at the specified depth will enter the sampling bottle 7. During this process, the spiral plate 12 can improve the smoothness of water entering the sampling bottle 7. After sampling, the upright 2 is removed from the water. At this time, the sealing plate 11 will seal the top of the sampling bottle 7 under the push of the telescopic spring 6 to prevent water from re-entering. After sampling, the water in the sampling bottle 7 is transferred to the collection bottle through the plug 8, completing the water collection work at the specific depth.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
