Description

Technical Field

[0001] The utility model belongs to the technical field of water quality management, in particular to a water environment management sampling device. Background Art

[0002] For water environment management of rivers and lakes, the water quality must first be tested, including the microbial content, impurities, CODs, silt, etc. in the water. The type of drug to be added and the method of management can be determined based on the degree of water pollution and the main pollutants.

[0003] Water quality testing must first sample the water body. Currently, many methods extract water as a sample. This method may lead to inaccurate test results because the water body has a certain self-purification ability, and impurities will settle spontaneously, resulting in inaccurate test results during the water quality testing process. Therefore, the silt corresponding to the riverbed of rivers and lakes can be tested. Waters with poor water quality have thicker silt, and there are a lot of humus in the silt, so the degree of pollution can be judged and targeted governance can be carried out. The existing sampling of silt is not very standardized, and the thickness of the silt cannot be accurately calculated, and it is easy to repeat sampling. Therefore, the utility model is aimed at water environment management, and a device for silt sampling is prepared, which can accurately locate the thickness of the silt. Utility Model Content

[0004] The utility model aims to provide a water environment treatment sampling device. Aiming at water environment treatment, a device for sludge sampling is prepared, which can accurately locate the thickness of the sludge.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] A water environment treatment sampling device comprises a sampling tube, a tube body structure, a lower end of which is an oblique side, and an upper side is a horizontal opening side, wherein the oblique side is used to be inserted into a riverbed to a certain depth;

[0007] A movable baffle is installed on the oblique side corresponding to the sampling tube. The baffle is hinged to the inner wall of the sampling tube on one side and flipped to fit. The baffle is a circular plate structure with the center located at the axis of the sampling tube. The other side of the sampling tube corresponding to the hinged side of the baffle has a limiting portion supporting the baffle.

[0008] Furthermore, the baffle is arched along a circular radial arc, and the arching curvature is the same as the curvature of the side wall of the sampling tube. The outer wall of the sampling tube corresponding to the oblique side has a thread, and the outer wall of the sampling tube corresponding to the upper horizontal opening side is symmetrically fixed with a handle. The part of the sampling tube corresponding to the oblique side is detachably installed, and the installation side is threaded sleeve installation, and the baffle is located at the corresponding part of the oblique side. A push rod is also configured on the upper opening side of the sampling tube, and a push plate is vertically fixed to the end of the push rod. The push plate is circular, and the push rod is fixed at the center of the circle.

[0009] Furthermore, the side wall of the sampling tube has a strip groove, which is opened along the length direction of the sampling tube and is sealed with a transparent material to serve as an observation window.

[0010] The utility model has the following beneficial effects: the sampling tube is a tube structure, which is inserted into the soft sludge. When the sampling tube is pulled out, the sludge automatically falls from the tube body under the action of gravity, and the sampling effect cannot be achieved. In order to prevent this phenomenon from happening, a baffle is installed at the position corresponding to the oblique mouth on the lower side of the sampling tube. One side of the baffle is hinged to the inner wall of the sampling tube, and the other side is supported on the limiting part. The baffle can achieve a relatively sealed effect on the oblique mouth side of the sampling tube. When the sampling tube is inserted into the sludge, the resistance of the sludge itself pushes the baffle open, and the baffle flips along the hinged side, and the sludge enters the sampling tube. When the sampling tube is pulled out, the baffle is reset under the action of the sludge's gravity, and the baffle is supported on the limiting part again to prevent the sludge from falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for describing the embodiments are briefly introduced below.

[0012] Figure 1 : Schematic diagram of the structure of the utility model.

[0013] Figure 2 : Schematic diagram of the oblique side disassembly structure of the utility model.

[0014] In the accompanying drawings, the components represented by the reference numerals are listed as follows: sampling tube 1 , baffle 2 , thread 3 , handle 11 , push rod 4 , push plate 41 , strip groove 12 . DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] like Figure 1-2As shown: A water environment management sampling device includes a sampling tube 1, a tube body structure, made of stainless steel, with a thin tube wall, a length of about 3-5m, a beveled side at the lower end, an inclination angle of the cut side less than 30°, and a horizontal opening side at the upper side. The beveled side is used to insert into the riverbed to a certain depth; the beveled side is convenient for inserting into the silt for sampling.

[0017] A movable baffle 2 is installed on the oblique side corresponding to the sampling tube 1. The baffle 2 is hinged to the inner wall of the sampling tube 1 on one side and flipped to fit. The baffle 2 is a circular plate structure with the center located at the axis of the sampling tube 1. The other side of the sampling tube 1 corresponding to the hinged side of the baffle has a limiting portion supporting the baffle 2.

[0018] The sampling tube is a tube structure. When the sampling tube is inserted into the soft silt, the silt will automatically fall out of the tube body under the action of gravity when the sampling tube is pulled out, and the sampling effect cannot be achieved. In order to prevent this phenomenon from happening, a baffle is installed at the position corresponding to the oblique mouth on the lower side of the sampling tube. One side of the baffle is hinged to the inner wall of the sampling tube, and the other side is supported on the limit part. The baffle can achieve a relatively sealed effect on the oblique mouth side of the sampling tube. When the sampling tube is inserted into the silt, the resistance of the silt itself pushes the baffle open, and the baffle flips along the hinged side, and the silt enters the sampling tube. When the sampling tube is pulled out, the baffle is reset under the action of the silt's gravity, and the baffle is supported on the limit part again to prevent the silt from falling.

[0019] When sampling, use boats or other vehicles to reach sampling points in lakes and rivers, and conduct sampling when the water depth meets the length requirements of the sampling tube.

[0020] like Figure 2 As shown: the baffle 2 is arched along a circular radial arc, and the arching curvature is the same as the curvature of the side wall of the sampling tube. In this way, when the silt pushes the baffle open, the baffle can be pressed against the inner wall of the sampling tube as much as possible, so that the mouth of the sampling tube is opened as much as possible to allow the silt to pass through. The outer wall of the sampling tube 1 corresponding to the oblique side has a thread 3, and the outer wall of the sampling tube 1 corresponding to the upper horizontal opening side is symmetrically fixed with a handle 11. The thread is a spiral convex ridge structure, which is used to rotate the sampling tube when inserted into the riverbed, and under the action of the thread, it is screwed into the deep silt and reaches the hard soil layer at the bottom of the riverbed as much as possible. The handle is convenient for hand-held force. The part of the sampling tube 1 corresponding to the oblique side is detachable and installed, and the installation side is threaded sleeve installation, and the baffle 2 is located at the corresponding part of the oblique side. After sampling, the oblique part is disassembled, and the internal silt is poured out for testing and other tests. At the same time, it is easy to clean for the next sampling. The upper opening side of the sampling tube 1 is also provided with a push rod 4, and a push plate 41 is vertically fixed to the end of the push rod 4. The push plate is circular, and the center of the circle is fixed with the push rod 4. When taking out the sample from the sampling tube, the push rod can be used to cooperate with the push plate to operate.

[0021] like Figure 1As shown: the side wall of the sampling tube 1 has a strip groove 12, which is opened along the length of the sampling tube and sealed with a transparent material, serving as an observation window for observing the internal sludge condition and judging the depth of the sludge.

[0022] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
