Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a water quality testing device based on environmental impact assessment. Background Technology
[0002] The existing system requires the prediction and assessment of potential environmental impacts after the implementation of planning and construction projects, and the proposal of countermeasures and measures to prevent or mitigate adverse impacts. This is known as environmental impact assessment (EIA), and water quality testing is a crucial part of this process.
[0003] For water samples collected from multiple regions and points, water quality testing is required. Before testing, a precipitant needs to be added for mixing, followed by sedimentation to achieve solid-liquid separation, making it easier to extract the clear liquid from the upper layer.
[0004] Common water quality monitoring mixing mechanisms often use fixed-size reagent tubes, making it difficult to simultaneously accommodate reagent tubes of different diameters and lengths. For example, when testing reagent tubes of various sizes ranging from 10mm to 25mm, traditional equipment requires frequent clamp changes or the use of multi-layer adapters, resulting in longer assembly times for a single batch of reagent tubes and reduced testing efficiency. Furthermore, it's impossible to assemble the next batch of reagent tubes in advance during the mixing process. For instance, when a batch of reagent tubes has finished mixing and entered the sedimentation stage, operators must wait until the current batch is completely finished before starting to clamp the next batch, leading to high equipment idle rates and making it difficult to meet the demands of high-frequency testing. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as low compatibility with reagent tubes and low operational efficiency, by proposing a water quality testing device based on environmental impact assessment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A water quality monitoring device based on environmental impact assessment includes a main body;
[0008] The swing frame is rotatably mounted inside the machine body, and the swing frame has a placement slot inside;
[0009] A placement rack is fitted into a placement slot. The placement rack includes multiple inner plates. Placement holes are provided on the top of the placement rack and on the surface of each inner plate. The size of all placement holes decreases from top to bottom to form a stepped structure.
[0010] The top cover is located on the swing frame. Some of the top cover is fixedly equipped with sliding frames, and the sliding frames are slidably arranged in the vertical part of the placement frame. The bottom of the top cover has multiple bottom grooves, and a cover plate is slidably arranged in each bottom groove. A compression spring is arranged between the cover plate and the inner wall of the bottom groove.
[0011] The reagent tube is inserted into the placement hole until it touches the bottom. When the top cover moves down, the top of the reagent tube enters the bottom groove and touches the cover plate. The cover plate clamps the top of the reagent tube under the action of spring force, realizing the adaptation of reagent tubes of various specifications.
[0012] In one possible design, a swing motor is installed inside the body, and the output shaft of the swing motor is coaxially connected to the rotation shaft of the swing frame.
[0013] One possible design also includes a snap-fit mechanism:
[0014] The latching mechanism includes a guard plate, a slide block, an insert plate, and a second compression spring;
[0015] The protective plate is rotatably mounted on one side of the top cover, and a slot is provided on the surface of the protective plate;
[0016] The slide block is fixed to the side wall of the swing frame, and the insert plate is slidably disposed inside the slide block, with one side of the insert plate being an inclined surface;
[0017] The second compression spring is installed inside the slide block, with its two ends connected to the insert plate and the inner wall of the slide block, respectively.
[0018] When the top cover moves down, the guard plate contacts the inclined surface, forcing the insert plate to retract until the second compression spring resets and inserts into the slot to fix the guard plate.
[0019] In one possible design, the cover plate surface is provided with a rubber pad.
[0020] In one possible design, the guard plate is in contact with the side wall of the swing frame when closed, and the inclined surface of the insert plate is aligned with the movement trajectory of the guard plate.
[0021] In one possible design, while batches of reagent tubes are being mixed in the swing rack, the next batch of reagent tubes is pre-loaded into a spare rack, and the rack is directly replaced after mixing is complete.
[0022] In this application, during actual use, reagent tubes containing water samples and precipitants are placed in the placement rack. Because the placement holes on the top of the rack and on each inner plate surface are of different sizes and arranged from largest to smallest from top to bottom, the reagent tubes can be directly inserted downwards until they reach the corresponding bottom. The rack is then inserted into the placement slot, and the top cover is moved downwards. At this point, the tip of the reagent tube will enter the bottom slot and contact the cover plate, causing the cover plate to move inwards. The first compression spring is then compressed, and the top cover is then closed. Continue moving until it reaches the end, where the cover plate clamps the reagent tube, and the protective plate touches the inclined surface of the insert plate, causing the insert plate to move inward. Then, the second compression spring resets the protective plate, thus completing the assembly. Subsequently, the swing motor can be driven to swing the swing frame and the internal reagent tubes to mix them. While mixing this batch of water samples, the reagent tubes for the next batch can be assembled in advance. When the current batch is finished and taken out for sedimentation, the reagent tubes for the next batch can be directly installed into the swing frame, thereby improving efficiency.
[0023] In this utility model, the water quality testing device based on environmental impact assessment can be used to place and clamp various types of reagent tubes through stepped placement holes and clamping components, thereby improving efficiency and increasing adaptability.
[0024] In this utility model, the water quality testing device based on environmental impact assessment can achieve the goal of pre-assembling the next batch of reagent tubes by utilizing the mixing time, thereby improving the utilization rate of the equipment and ultimately improving the testing efficiency through a pre-assembly mechanism.
[0025] In this invention, various reagent tubes of different specifications can be placed and fixed for mixing, improving their adaptability, and the whole batch of water samples can be conveniently monitored for water quality, thereby improving the final detection efficiency.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0033] Example 1
[0034] Reference Figure 1-2 A detection device includes: a body 1, a swing frame 2, a placement frame 4, and a top cover 8.
[0035] Reference Figure 3-4 Inside the main body 1, a swing frame 2 is rotatably mounted via bearings. The rotation shaft of the swing frame 2 is coaxially connected to the output shaft of a swing motor fixed inside the main body 1, achieving reciprocating swing through motor drive. The water quality analyzer is located beside it. A placement slot 3 is provided inside the swing frame 2, and a placement rack 4 is embedded in this slot. Multiple inner plates 5, evenly spaced on their top and interior surfaces, each have placement holes 6 with decreasing diameters, forming a stepped structure where the hole diameter gradually decreases from top to bottom. This allows reagent tubes of different sizes to be inserted axially until they reach the bottom limit.
[0036] A sliding frame 7 is fixed to one side of the top cover 8. The sliding frame 7 is slidably sleeved on the outer wall of the vertical part of the swing frame 2 to realize the vertical lifting and lowering of the top cover 8. A bottom groove 10 is opened at the bottom of the top cover 8 corresponding to the placement hole 6. A cover plate 12 is slidably arranged in each bottom groove 10 through a guide rail. A compression spring 11 is pressed between the cover plate 12 and the inner wall of the bottom groove 10. When the top cover 8 moves downward, the top of the reagent tube enters into the bottom groove 10 and abuts against the cover plate 12. The cover plate 12 will automatically clamp the top of the reagent tube under the action of the spring force.
[0037] This application can be used in the field of environmental monitoring, or in other fields applicable to this application.
[0038] Example 2
[0039] refer to Figure 5An improvement upon Embodiment 1: A water quality testing device based on environmental impact assessment, applied to the field of environmental monitoring. A protective plate 9 is hinged to the other side of the top cover 8, and when closed, the protective plate 9 fits against the side wall of the swing frame 2. The side wall of the swing frame 2 is equipped with a locking mechanism, including a slide 14 fixed to the swing frame 2. An insert plate 16 is slidably disposed within the slide 14, and a second compression spring 17 is pressed between the insert plate 16 and the inner wall of the slide 14. When the top cover 8 pushes down on the protective plate 9, its side presses against the inclined surface 15 of the insert plate 16, forcing the insert plate 16 to retract. After the top cover 8 moves to its end, the insert plate 16 rebounds under the spring force and inserts into the slot 13 on the side wall of the protective plate 9, completing a quick locking.
[0040] When mixing the current batch, the next set of reagent tubes is pre-loaded into the spare rack 4, and can be directly replaced after the previous batch is completed, achieving seamless connection and thus improving efficiency.
[0041] After mixing, release the locking mechanism and lift the top cover 8. Horizontally pull the placement rack 4 along with the reagent tube from the swing rack 2. Then, move the placement rack 4 to one side for sedimentation. Keep the reagent tube vertical and stand for 15-30 minutes, allowing gravity to separate the solid and liquid layers. Then, slowly extract the upper clear liquid along the tube wall using a pipette, avoiding disturbing the lower sediment. The extraction volume should be 60%-70% of the tube's internal volume. The clear liquid can then be injected into the water quality analyzer's detection pool. Select the corresponding reagent tube according to the detection parameters, start the detection program, and obtain data. The water quality analyzer can be a commonly available multi-parameter water quality analyzer.
[0042] However, as is well known to those skilled in the art, the working principles and wiring methods of swing motors and water quality testers are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
[0043] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
