Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a sampling box for environmental impact assessment. Background Technology

[0002] Environmental impact assessment (EIA) is a crucial process for evaluating the potential environmental impacts of a construction project. Environmental sample collection is a fundamental and critical step in this process. Traditional sampling methods often rely on manual operation, which suffers from low sampling efficiency, susceptibility to sample contamination, and inconvenience. Therefore, developing an efficient, convenient, and reliable sampling kit is of great significance for improving the accuracy and efficiency of EIA.

[0003] Comparing with Chinese Patent Publication No. CN 218807476 U, a sampling box for environmental impact assessment is disclosed. The sampling box has two mounting plates fixedly connected to its inner wall, and a protective assembly is installed inside. The protective assembly includes two first sleeves, the bottoms of which are fixedly connected to the interior of the sampling box, and spring shock absorbers are fixedly connected inside each first sleeve. This sampling box for environmental impact assessment, after the sampled test tube passes through the fixed plate and rests on the top of the support base, inserts the test tube plug connected to the cover plate into the test tube to seal it. Simultaneously, the cover plate rests on top of the two support plates, and the box cover is placed on top of the sampling box. A connecting spring is movably connected to a connecting column. Pulling two locking pins causes them to move apart under the action of a locking spring, bringing the slots inside the box cover and the locking pins to the same level. Releasing the two locking pins allows them to engage with the two slots, thus fixing the test tube inside the sampling box.

[0004] The disadvantages of the above patent are: the reagents inside the box are arranged relatively loosely, which wastes storage space; when the sampling location is far away and the sample volume is large, the sampling box with small storage capacity is not practical. Utility Model Content

[0022] 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.

[0023] Please see Figures 1-4 An environmental impact assessment sampling box includes a transfer component 1 for easy carrying, a protective component 2 for buffering external impacts in the middle of the transfer component 1, and a storage component 3 for placing multiple samples inside the protective component 2.

[0024] In this embodiment: the transfer component 1 includes a handle 101, a connecting shaft 102 is provided at the bottom of the handle 101, a limit frame 103 is provided inside the connecting shaft 102, and the connecting shaft 102 is connected to the limit frame 103 by a bearing.

[0025] In this embodiment: the protective component 2 includes a base 201, with symmetrically arranged locking blocks 202 on both sides of the base 201, and a protective cover 203 between the two locking blocks 202. A plurality of spring plates 204 are evenly arranged on the periphery of the top surface of the protective cover 203. A through hole 205 is opened in the middle of the base 201, and a fitting rod 206 is provided on the top of the protective cover 203. The fitting rod 206 is a two-lobed type. When the two protective covers 203 are closed and inserted along the limiting frame 103, the locking blocks 202 rotate inward to fix the protective cover 203. At this time, the test tube 307 is placed inside the protective cover 203. The first sleeve 301 passes through the through hole 205, and the top of the support column 303 is supported in multiple directions by the spring plates 204. If shaking occurs during transportation, the spring plates 204 and the springs 308 respectively buffer the external forces in the horizontal and vertical directions to ensure the transportation stability of the test tube 307 in the box.

[0026] In this embodiment: the storage component 3 includes a first sleeve 301, a spring 308 at the bottom of the first sleeve 301, a second sleeve 302 slidably disposed at the top of the first sleeve 301, the second sleeve 302 being shorter than the first sleeve 301, a support column 303 slidably disposed at the top of the second sleeve 302, six layers of rubber pads 304 equidistantly disposed on the first sleeve 301, the second sleeve 302, and the support column 303, twenty-four placement holes 305 evenly distributed on the rubber pads 304, and twelve foam pads 306 evenly distributed on the rubber pads 304. It can hold twelve test tubes 307. The bottom end of the first sleeve 301 is located inside the through hole 205. The bottom end of the spring 308 abuts against the base 201. The sample is stored in the test tube 307. The test tube 307 is placed on the rubber pad 304. The position of the test tube 307 is restricted by the placement hole 305. The support column 303 is pressed down to make it slide along the second sleeve 302. At the same time, the second sleeve 302 slides along the first sleeve 301, so that the test tubes 307 are close to each other. Finally, each test tube 307 has two placement holes 305 at the top and middle to limit it. The bottom of each test tube 307 contacts the foam pad 306.

[0027] Working principle: The sample is placed in test tube 307, which is then placed on rubber pad 304. The position of test tube 307 is restricted by placement holes 305. The support column 303 is pressed down to slide along the second sleeve 302, while the second sleeve 302 slides along the first sleeve 301, bringing the test tubes 307 closer together. Finally, each test tube 307 is limited by two placement holes 305 at the top and middle. The bottom of each test tube 307 contacts the foam pad 306, and the bottom end of the spring 308 rests against the bottom. On seat 201, two protective covers 203 are closed and inserted along the limiting frame 103. The locking block 202 rotates inward to fix the protective cover 203. At this time, the test tube 307 is placed inside the protective cover 203. The first sleeve 301 passes through the through hole 205. The top of the support column 303 is supported in multiple directions by the spring sheet 204. If shaking occurs during transportation, the spring sheet 204 and the spring 308 will buffer the external force in the horizontal and vertical directions respectively to ensure the transportation stability of the test tube 307 in the box.

[0028] 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.
