Detailed Implementation

[0034] Reference Figure 1 As shown, this utility model provides a technical solution: a concentration device for water sample detection and analysis, including a main support 1, a positioning structure 2 on the upper surface of the main support 1, and a partition structure 3 on the inner side of the main support 1.

[0035] The specific settings and functions of its positioning structure 2 and partition structure 3 will be discussed below.

[0036] Reference Figures 1-3As shown in this embodiment: the positioning structure 2 includes a support plate 21 fixedly connected to the upper surface of the main support 1. Two sliding plates 22 are slidably connected to the inner side of the support plate 21. A bidirectional lead screw 26 is rotatably connected inside the support plate 21. The two sides of the bidirectional lead screw 26 have threads in opposite directions. The bidirectional lead screw 26 and the sliding plates 22 are internally threaded together. A positioning block 25 is fixedly connected to the end of the sliding plate 22. A rectangular hole 24 is provided on the upper surface of the main support 1. By setting the positioning structure 2, the positioning and clamping of containers of different sizes is facilitated, which to a certain extent improves the efficiency of water sample concentration in the container and enhances the performance of the concentration device. A reserved groove 28 is provided on the side of each of the two positioning blocks 25 that is close to each other. The reserved groove 28 can adapt to water sample containers of different diameters, achieving precise positioning by fitting against the outer wall of the container. The reserved groove 28 is a V-shaped groove. The V-shaped reserved groove 28 on the positioning block 25 can adapt to water sample containers of different diameters. A metal mesh 23 is fixedly connected to the inner side of the rectangular hole 24. The metal mesh 23 inside the rectangular hole 24 on the main support 1 provides auxiliary support to the bottom of the container, preventing it from tipping over. Both ends of the bidirectional lead screw 26 are fixedly connected to rotating blocks 27. The operator rotates the rotating blocks 27 at both ends of the bidirectional lead screw 26, utilizing the transmission action of the opposite threads on both sides of the bidirectional lead screw 26 to drive the two sliding plates 22 on the inner side of the support plate 21 to slide in opposite directions.

[0037] Reference Figures 1-2 and Figure 4 As shown, specifically, the partition structure 3 includes a limiting frame 35 fixedly connected to the inner side of the main support 1, and several partition strips 36 are slidably connected to the inner side of the limiting frame 35. By setting the partition structure 3, the quick partitioning of the inner side of the main support 1 is facilitated, and the subsequent unblocking of fuel on the partition strips 36 is also facilitated, thus improving the efficiency of subsequent fuel combustion to a certain extent. A spring 37 is fixedly connected between two partition strips 36. The spring 37 facilitates the quick reset of the partition strips 36 after movement. A connecting plate 31 is fixedly connected to the surface of the main support 1, and two limiting strips 32 are slidably connected inside the connecting plate 31. A pressure strip 34 is fixedly connected to the lower end of the two limiting strips 32, and several push blocks 38 are fixedly connected to the lower surface of the pressure strip 34. The push blocks 38 are inserted between adjacent partition strips 36. The lower side of the push block 38 is an isosceles triangular plate structure. The push block 38 with an isosceles triangular plate structure on its lower side improves the efficiency of insertion between adjacent partition strips 36. The connecting plate 31 is internally threaded with a screw 33, which is internally rotatably connected to the pressure strip 34. Rotating the screw 33 will drive the pressure strip 34 to move up and down.

[0038] Working principle: When the concentration device for water sample testing and analysis is in operation, the water sample container is first stably fixed by the positioning structure 2. The operator rotates the rotating blocks 27 at both ends of the bidirectional lead screw 26. Utilizing the transmission action of the opposite threads on both sides of the bidirectional lead screw 26, the two sliding plates 22 on the inner side of the support plate 21 slide in opposite directions, causing the positioning blocks 25 to move closer or further apart. The V-shaped reserved groove 28 on the positioning block 25 can be adapted to water sample containers of different diameters. Precise positioning is achieved by fitting against the outer wall of the container. At the same time, the metal mesh 23 in the rectangular hole 24 on the main support 1 provides auxiliary support to the bottom of the container, preventing the container from tipping over and providing a stable bearing foundation for subsequent concentration operations. By setting up the positioning structure 2, the positioning and clamping of containers of different sizes is facilitated, which to a certain extent improves the efficiency of water sample concentration in the container and enhances the performance of the concentration device.

[0039] When using fuels such as coal to heat the container, the fuel can be placed above multiple spacers 36 for heating. After heating, ash often falls to the bottom of the main support 1. When ash gets stuck between the spacers 36, the screw 33 can be rotated, which will drive the pressure bar 34 to move up and down. After the pusher 38 on the pressure bar 34 is pulled out from between adjacent spacers 36, the spacers 36 can slide inside the limiting frame 35, pulling the spacers 36 a certain distance apart, thus allowing the residue to fall off and clearing the blockage. After the assembly, the screw 33 can be rotated again to insert the push block 38 into the position between the adjacent spacers 36. The push block 38, with its isosceles triangular plate structure on the lower side, improves the efficiency of inserting between the adjacent spacers 36. The spring 37 facilitates the quick reset of the spacers 36 after movement, further improving the efficiency of quick separation between the spacers 36. By setting the separation structure 3, it is convenient to quickly divide the inner side of the main support 1, and it is also convenient to clear the fuel on the separation strips 36, which improves the efficiency of subsequent fuel combustion to a certain extent.
