Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling technology, and in particular to a portable sampling device for water pollution detection. Background Technology
[0002] In the field of water resource protection and monitoring, water pollution detection is of paramount importance. Existing portable sampling devices for water pollution detection are mostly based on integrated sampling boxes, whose core functions are concentrated on water sample storage, sampling tool storage and reagent storage, which can meet the needs of water sample collection in field environments such as the field and shore.
[0003] In actual testing operations, staff often need to perform rapid on-site tests on water samples for pH, turbidity, residual chlorine, etc., to obtain real-time data. However, there is a lack of fixed, flat work surfaces on-site. Staff have to place test reagent bottles, colorimetric tubes, portable detectors, etc. on the ground or inside the sampling box. The ground can easily cause reagent contamination, and the inside of the sampling box is not convenient for observing changes in reagents. Furthermore, on-site testing requires clear observation of colorimetric results and instrument readings. Without a dedicated work surface, the test equipment is placed haphazardly, which can easily affect testing efficiency. Therefore, we propose a portable sampling device for water pollution testing, which solves the problem of the lack of temporary work surfaces on-site. Utility Model Content

This device can solve the problem that in actual testing operations, staff often need to perform rapid on-site testing of water samples for pH value, turbidity, residual chlorine, etc., to obtain real-time data. However, there is a lack of fixed and flat work surfaces on-site. Staff need to place test reagent bottles, colorimetric tubes, portable detectors, etc. on the ground or inside the sampling box. The ground can easily cause reagent contamination, and the inside of the sampling box is not convenient for observing changes in reagents. Furthermore, on-site testing requires clear observation of colorimetric results, instrument readings, etc. Without a dedicated operating platform, the test equipment is placed in a mess, which can easily affect the testing efficiency.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a portable sampling device for water pollution detection, comprising:
[0030] Water sampling box 1, the top of water sampling box 1 is hinged to box cover 2, and the inside of water sampling box 1 is equipped with an operating table positioning structure.
[0031] The operating table positioning structure includes a storage box 4 and two fixed seats 10. The storage box 4 is welded and fixed to the inner wall of the water quality sampling box 1. A sliding plate 11 is slidably connected inside the storage box 4. The two fixed seats 10 are welded and fixed to the top of the sliding plate 11. A rotating seat 9 is rotatably mounted on the opposite side of the two fixed seats 10 through bearings. A temporary operating table 5 is welded and fixed on the side of the rotating seat 9 away from the water quality sampling box 1. A slot 2 15 is opened on the side of the rotating seat 9 near the box cover 2. A slot 14 is opened on the side of the rotating seat 9 away from the slot 2 15. A limiting groove 13 is opened in the fixed seat 10 near the slot 14. A through groove 16 is opened in the fixed seat 10 near the slot 2 15. A rubber rod 20 is interference-fitted inside the through groove 16. The end of the rubber rod 20 near the rotating seat 9 is inserted into the inside of the slot 2 15.
[0032] The operating table positioning structure also includes a limiting slide plate 19 and a limiting rod 17. The limiting slide plate 19 is slidably connected inside the limiting slide groove 13. The limiting rod 17 is welded and fixed inside the limiting slide plate 19. The end of the limiting rod 17 near the rotating seat 9 slides to the outside of the limiting slide groove 13 and is inserted into the inside of the slot 14. The end of the limiting rod 17 away from the rotating seat 9 slides to the outside of the limiting slide groove 13. A spring 18 is sleeved on the outside of the limiting rod 17. One end of the spring 18 is welded and fixed to the limiting slide plate 19. The end of the spring 18 away from the limiting slide plate 19 is welded and fixed to the inner wall of the limiting slide groove 13.
[0033] An elastic rope 21 is attached to the end of the rubber rod 20 away from the rotating seat 9. The end of the elastic rope 21 away from the rubber rod 20 is attached to the nearby fixed seat 10. A temporary placement rack 6 is welded and fixed inside the temporary operating table 5.
[0034] A magnetic strip 12 is attached to the bottom of the sliding plate 11, and a magnetic strip 8 is attached to the bottom of the water sampling box 1 and is located inside the storage box 4. The magnetic strip 12 and the magnetic strip 8 are magnetically connected. There are two operating platform positioning structures, which are symmetrically arranged on the water sampling box 1.
[0035] A support frame 7 is welded and fixed to the inner bottom wall of the water sampling box 1, and a test tube placement platform 3 is placed on top of the support frame 7.
[0036] Example 1:
[0037] When the temporary operating table 5 is needed, first pull out the temporary operating table 5 so that the magnetic strip 2 12 separates from the magnetic strip 1 8. When it is pulled upward until the top of the sliding plate 11 contacts the inner top wall of the sliding plate 4, pull the rubber rod 20 out of the slot 2 15 to release the initial positioning of the rotating seat 9. Then, pull the limiting rod 17. The limiting rod 17 will drive the limiting slide plate 19 to slide in the limiting slide groove 13 and compress the spring 18, so that one end of the limiting rod 17 is pulled out of the slot 1 14, thereby releasing the limitation of the rotating seat 9.
[0038] Next, rotate the temporary operating table 5 to make the rotating seat 9 rotate. When the temporary operating table 5 rotates to a horizontal angle, release the limiting rod 17. Under the elastic force of the spring 18, the end of the limiting rod 17 near the rotating seat 9 will be inserted into the slot 14 to position the rotating seat 9. Insert the rubber rod 20 into the slot 25 for double locking, so that the temporary operating table 5 is stably in the unfolded state, which is convenient for the operator to perform relevant testing operations. After the operation is completed, follow the reverse steps to put the temporary operating table 5 back into its original position.
[0039] Example 2:
[0040] With the elastic rope 21 in place, one end of the elastic rope 21 is fixed to the end of the rubber rod 20 away from the rotating seat 9, and the other end is fixed to the nearby fixed seat 10. This physical connection method ensures that the rubber rod 20 is always associated with the main body of the device, and will not be completely separated from the device no matter where the rubber rod 20 is pulled out.
[0041] Furthermore, when using the device, when the temporary operating table 5 is not in use, it is stored in the storage box 4 via the rotating seat 9. At this time, the elastic rope 21 is in a relaxed state, and one end of the rubber rod 20 is inserted into the slot 15 of the rotating seat 9 to initially position the rotating seat 9 and prevent it from rotating arbitrarily. At the same time, the sliding plate 11 is stored in the storage box 4, and the magnetic strip 12 at the bottom of the sliding plate 11 is magnetically connected to the magnetic strip 8 at the bottom of the storage box 4 of the water quality sampling box 1, so that the sliding plate 11 is firmly fixed in the storage box 4, thereby putting the temporary operating table 5 in a stored state without occupying extra space.
[0042] When the temporary operating table 5 is needed, first pull out the temporary operating table 5 so that the magnetic strip 2 12 separates from the magnetic strip 1 8. When it is pulled upward until the top of the sliding plate 11 contacts the inner top wall of the sliding plate 4, pull the rubber rod 20 out of the slot 2 15 to release the initial positioning of the rotating seat 9. Then, pull the limiting rod 17. The limiting rod 17 will drive the limiting slide plate 19 to slide in the limiting slide groove 13 and compress the spring 18, so that one end of the limiting rod 17 is pulled out of the slot 1 14, thereby releasing the limitation of the rotating seat 9.
[0043] Next, rotate the temporary operating table 5 to make the rotating seat 9 rotate. When the temporary operating table 5 rotates to a horizontal angle, release the limiting rod 17. Under the elastic force of the spring 18, the end of the limiting rod 17 near the rotating seat 9 will be inserted into the slot 14 to position the rotating seat 9. Insert the rubber rod 20 into the slot 25 for double locking, so that the temporary operating table 5 is stably in the unfolded state, which is convenient for the operator to perform relevant testing operations. After the operation is completed, follow the reverse steps to put the temporary operating table 5 back into its original position.
[0044] The test tube placement platform 3 is placed on top of the support frame 7, which provides stable support for the test tube placement platform 3. Operators can place the collected water sample test tubes on the test tube placement platform 3 for subsequent complex testing and analysis.
[0045] During on-site testing, the temporary operating table 5 can be unfolded to a horizontal state through the operating table positioning structure. The limiting rod 17 is inserted into the slot 14 of the rotating seat 9 under the elastic force of the spring 18, and the rubber rod 20 is inserted into the slot 15 for double locking, so that the temporary operating table 5 is stable and immovable. This provides the staff with a fixed and flat operating surface. The staff can neatly place the test reagent bottles, colorimetric tubes, portable detectors and other testing equipment on the temporary operating table 5, avoiding the problem of reagent contamination caused by placing them on the ground and the problem of inconvenience in observing reagent changes when placed inside the water quality sampling box 1, ensuring a clean testing environment and clear test observation.
[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
