Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a sample collection device for water environment treatment. Background Technology

[0002] Water environment management is one of the important elements of water conservancy construction.

[0003] Currently, existing water environment management sample collection devices can generally only collect water samples from the environment, but cannot sample the silt at the bottom of the water. This results in certain limitations in the samples, affecting the analysis results of the water environment and hindering the rational management of the water environment.

[0004] Therefore, this application provides a sample collection device for water environment treatment to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a sample collection device for water environment treatment to solve the problem that the existing sample collection devices for water environment treatment can only collect water bodies, resulting in the limitation of the sample.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A sample collection device for water environment treatment includes a collection rod for extending into the bottom of the water, a vertical sludge collection tube detachably installed at the bottom of the collection rod, the lower end of the sludge collection tube being a pointed cone, and an opening provided at the top of the sludge collection tube;

[0008] The sampling rod is also fitted with a counterweight plate that can move up and down. The counterweight plate is horizontally set, and a vertical screw is installed on the upper end of the counterweight plate. A vertical water sample collection tube is detachably installed on the top of the screw. A sealing cap is also installed in the middle of the sampling rod. The sealing cap is located directly above the water sample collection tube and is connected to the top opening of the water sample collection tube.

[0009] Optionally, a movable cylinder is fixed in the middle of the counterweight plate. The movable cylinder is movably sleeved on the collection rod, and the movable cylinder can only move vertically up and down along the collection rod.

[0010] Optionally, the screw thread passes through the counterweight plate, the top of the screw is fixed to a fixing seat, and the bottom of the water sample collection tube is threadedly inserted into the fixing seat.

[0011] Optionally, the middle part of the collection rod is provided with a fixing frame that can be adjusted up and down, and the sealing cover is fixed on the fixing frame.

[0012] Optionally, the middle part of the collection rod is provided with a threaded part, and the fixing frame is threaded onto the threaded part.

[0013] Optionally, the bottom end of the collection rod extends vertically into the bottom of the collection rod and is threadedly inserted.

[0014] Optionally, a telescopic rod is fitted to the top of the collection rod, and a flange for connecting the collection rod is fixed to the lower end of the telescopic rod.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above scheme, thanks to the combination of the sampling rod, silt sampling tube, counterweight plate, water sampling tube and sealing cap, the silt sampling tube can be inserted into the bottom of the water to collect silt, and the water sampling tube can be used to collect water samples. Thus, water and silt samples are collected simultaneously in the aquatic environment, which improves the diversity of samples and helps to improve the accuracy of the analysis results of water environment treatment.

[0017] In the above scheme, thanks to the movable installation of the counterweight plate on the collection rod and the fixed installation of the silt collection tube and the sealing cap on the collection rod, when the counterweight plate is in contact with the silt at the bottom of the water, the collection rod is continuously inserted to collect silt using the silt collection tube. During this process, the sealing cap can be used to cover the port of the water sample collection tube to prevent sediment from entering the water sample collection tube, thus ensuring the quality of the water sample and silt sample collection at the same time.

[0018] In summary, this device can simultaneously collect water and silt samples, which helps to improve the analysis results of water environment management. Attached Figure Description

[0027] The present invention provides a sample collection device for water environment treatment, which is described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0028] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0032] like Figure 1 and Figure 3 As shown, an embodiment of this utility model provides a sample collection device for water environment treatment, including a collection rod 1 for extending into the bottom of the water. A vertical sludge collection tube 101 is detachably installed at the bottom of the collection rod 1. The lower end of the sludge collection tube 101 is conical, and the top of the sludge collection tube 101 has an opening. Specifically, the bottom end of the collection rod 1 extends vertically into the bottom of the collection rod 1 and is threadedly inserted.

[0033] Cooperate Figure 4 As shown, the top of the collection rod 1 is fitted with a telescopic rod 2, and the lower end of the telescopic rod 2 is fixed with a flange 201 for connecting the collection rod 1, so that the device can be inserted into the bottom of the water and use the silt collection tube 101 to collect silt.

[0034] like Figure 1 and Figure 2 As shown, a counterweight plate 3 that can move up and down is also sleeved on the collection rod 1. The counterweight plate 3 is set horizontally. Specifically, a movable cylinder 301 is fixed in the middle of the counterweight plate 3. The movable cylinder 301 is movably sleeved on the collection rod 1, and the inner wall of the movable cylinder 301 is provided with a vertical sliding edge, so that the movable cylinder 301 can only move up and down vertically along the collection rod 1.

[0035] Meanwhile, a vertical screw 4 is threaded into the upper end face of the counterweight plate 3, and a fixing seat 401 is fixed at the top of the screw 4. A vertical water sample collection tube 5 is threaded onto the fixing seat 401, and a sealing cover 6 is installed in the middle of the collection rod 1. The sealing cover 6 is located directly above the water sample collection tube 5 and is mated with the top opening of the water sample collection tube 5.

[0036] The sampling rod 1 has a threaded part 102 in the middle, and a fixing bracket 601 is threaded on the threaded part 102. The sealing cover 6 is fixed on the fixing bracket 601, so that the height position of the sealing cover 6 on the sampling rod 1 can be adjusted as needed.

[0037] The working principle provided by this utility model is that, when using the water environment treatment sample collection device, the retractable telescopic rod 2 can be used to vertically insert the collection rod 1 into the water environment. At this time, the counterweight plate 3 will abut against the upper port of the sludge collection tube 101 due to its own weight, and the upper port of the water sample collection tube 5 will separate from the sealing cover 6, so that the water sample collection tube 5 can automatically collect water samples.

[0038] When the counterweight plate 3 is placed on the surface of the silt in the water, the silt collection tube 101 will drill into the silt to collect silt samples by further inserting the collection rod 1 downwards. The sealing cover 6 will move down as the collection rod 1 descends to seal the upper port of the water sample collection tube 5, so as to prevent the silt and sand from entering the water sample collection tube 5 and causing sample contamination.

[0039] After collecting the silt and letting it stand for a period of time to ensure that the bottom of the water is no longer turbid, the collection rod 1 can be lifted until the upper end of the silt collection tube 101 touches the lower end of the counterweight plate 3, so that the entire device can be lifted out of the water environment. During the lifting process, the lower end of the counterweight plate 3 will continue to cover the upper end of the silt collection tube 101 to prevent the silt from spreading into the water and to ensure the integrity of the silt sample.

[0040] In summary, this device can simultaneously collect water and silt samples, which helps to improve the analysis results of water environment management.

[0041] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
