DETAILED DESCRIPTION
[0024] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.
[0025] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.
[0026] As shown in Figures 1-5 The present application provides a sampler for water quality detection with impurity removal function, comprising: a water taking device 1, and an inner layer 2 is arranged at the opening of the lower end of the water taking device 1;
[0027] Specifically, as shown in Figure 2 The upper end of the inner layer 2 is fixedly connected with a plurality of spring rods 3, the upper end of the spring rod 3 is fixedly connected with the lower end of the water baffle 4, the outer side of the water baffle 4 is fixedly connected with a rubber layer 5, and the outer side of the rubber layer 5 is movably connected with the inner side of one side of the inner layer 2;
[0028] In this embodiment: when the spring rod 3 is retracted, it pulls the water baffle 4 to fix it inside the inner layer 2. It is connected to the side wall of the inner layer 2 by a waterproof rubber layer 5. After the water is taken by the water collector 1, it can prevent water from seeping out from the lower inner layer 2, thereby collecting the sampled water and ensuring the normal transfer of the sampled water after the sampling is completed.
[0029] The outer barrel 6 has a water inlet 7 at its lower end. The water sampler 1 is placed inside the outer barrel 6. Multiple filter screens 10 are stacked on the upper end of the water inlet 7 to filter out impurities carried in the sampled water.
[0030] Specifically, such as Figure 4 As shown, multiple fixing rods 9 are fixedly connected inside the water inlet 7. The fixing rods 9 are movably connected inside the through hole 11, and the through hole 11 is set inside the outer ring of the filter screen 10. A limiting plate 12 is installed on the upper end of the filter screen 10, and the lower ends of the four limiting screws 13 installed on the limiting plate 12 are threaded to the upper end of the fixing rods 9.
[0031] In this embodiment: the three filter screens 10 are installed with the through holes 11 aligned with the fixing rod 9, and the four limiting screws 13 on the limiting plate 12 are installed on the fixing rod 9 for fixation, thereby restricting the position of the three filter screens 10. The three sets of filter screens 10 are used to block the impurities carried in the sampled water, thereby improving the impurity removal effect. When the filter screens 10 are replaced periodically, only the limiting plate 12 needs to be disassembled, and the installation and disassembly are relatively convenient.
[0032] The bottom plate 14 is fixedly connected to the lower end of the outer barrel 6 at its upper end, and the bottom plate 14 is provided with a flow channel 15 inside. The flow channel 15, the water inlet 7 and the lower opening of the water sampler 1 are at the same horizontal position. The flow channel 15 is provided with a sliding chamber 16 inside, and a moving plate 18 is slidably connected inside the sliding chamber 16 to block or allow the sampled water to pass through the flow channel 15.
[0033] like Figure 5 As shown, a slave rod 23 is rotatably connected inside the protective rod 17. A control end 24 is fixedly connected to the upper end of the slave rod 23. A second helical gear 22 is fixedly connected to the lower end of the slave rod 23. The outer side of the second helical gear 22 is meshed with the outer side of the first helical gear 21. A main rod 20 is fixedly connected inside the first helical gear 21. Both ends of the main rod 20 are rotatably connected inside the sliding chamber 16. The end of the main rod 20 away from the first helical gear 21 is a threaded rod 19. The outer side of the threaded rod 19 is threadedly connected to the inside of the moving plate 18.
[0034] In the embodiment, the control end 24 is manually rotated, the rotation of the lower end of the rod 23 drives the rotation of the second bevel gear 22, and then drives the rotation of the first bevel gear 21, the main rod 20 drives the rotation of the threaded rod 19, and the effect of controlling the left and right sliding of the moving plate 18 in the sliding bin 16 is achieved. When not in use, the moving plate 18 is moved to the through groove 15 for placement, which can achieve the effect of isolating the water flow. When in use, the moving plate 18 is moved from the through groove 15 to the inside of the bottom plate 14, which ensures that the sampling water can normally flow through the through groove 15, and facilitates sampling of the sampling water.
[0035] As shown in Figure 3 The fixed ring 8 is fixedly connected inside the outer barrel 6, and the fixed ring 8 is installed on the upper end of the water inlet 7, and the upper end of the fixed ring 8 abuts against the lower end of the water baffle 4.
[0036] In the embodiment, the fixed ring 8 is used to push the water baffle 4 to move upward. After the water sampler 1 is placed inside the outer barrel 6, the water baffle 4 is located at the upper end of the fixed ring 8. When the water sampler 1 is pushed to move downward, the reaction force provided by the fixed ring 8 pushes the water baffle 4 to move upward, and the eight spring rods 3 inside the inner layer 2 are stretched to move the water baffle 4 out of the inner layer 2. The sampling water can flow through the gap between the water baffle 4 and the inner layer 2 into the water sampler 1 for collection, achieving the effect of collecting the sampling water.
[0037] As shown in Figure 5 The protection rod 17 is further fixedly connected to the upper surface of the bottom plate 14, and the upper end of the protection rod 17 is fixedly connected to one side of the outer barrel 6.
[0038] In the embodiment, the control end 24 is located at the upper end of the water level and does not directly contact the sampling water. The protection rod 17 and the bottom plate 14 protect the first bevel gear 21 and the second bevel gear 22 from rusting after being soaked in water for a long time.
[0039] The specific scheme is: first, the lower end of the outer barrel 6 is fixed inside the sample water, and the water level of the sample water is located at the upper position of the middle part of the outer barrel 6; when taking water, the worker places the water taking device 1 inside the outer barrel 6, rotates the control end 24, controls the rotation of the second bevel gear 22 driven by the rod 23 to drive the rotation of the first bevel gear 21, thereby controlling the rotation of the main rod 20 and the threaded rod 19, and achieving the effect of controlling the movement of the moving plate 18 inside the sliding bin 16; after the moving plate 18 is moved away from the flow-through groove 15, the sample water flows through the flow-through groove 15 and is filtered by the three groups of filter screens 10, and then enters the inside of the outer barrel 6; the worker then pushes the water taking device 1 downward, the fixed ring 8 pushes open the water baffle 4, and the sample water enters the water taking device 1 through the gap between the water baffle 4 and the inner layer 2 to be collected, thereby achieving the effect of sampling the sample water; when sampling the sample water subsequently, the water taking device 1 only needs to be placed inside the outer barrel 6 to perform the sampling work, and the filter screen 10 inside the outer barrel 6 is convenient to disassemble; when the filter screen 10 outside is accumulated with sundries, causing slow water taking efficiency, the filter screen 10 can be disassembled and cleaned, thereby ensuring the effect of removing sundries carried in the sample water, and facilitating the subsequent detection work.
[0040] Those skilled in the art will understand that the discussion of any of the above embodiments is merely exemplary; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for the sake of brevity.
[0041] The present application is intended to cover all such alternatives, modifications, and variations as fall within the broad scope of the appended claims. Accordingly, any and all such alternatives, modifications and variations are intended to be encompassed by the appended claims.
