Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a filtration device for water quality testing. Background Technology

[0002] With the increasing severity of environmental pollution, the discharge of sewage and waste has caused significant water pollution, affecting not only the ecological environment but also domestic water supply. To understand the physical and chemical indicators of water quality, it is necessary to use equipment to sample and test the water. Water quality monitoring determines the types of pollutants in water bodies, the concentrations and trends of various pollutants, and evaluates the water quality status, which is crucial for ensuring water source safety.

[0003] When existing filtration equipment is used to test wastewater, it directly extracts and collects water samples for water quality testing. However, due to the different depths of the water at different sampling points, some suspended particles and sedimentary impurities in the water often gradually settle to the bottom due to gravity. This sedimentation phenomenon leads to significant differences in the composition distribution of the water at different depths. The surface water quality and the bottom water quality may differ greatly in terms of turbidity, organic matter content, microbial distribution, and chemical concentration. Therefore, it is easy to collect unrepresentative water samples by only sampling from a certain depth or by blindly sampling, which will cause the subsequent laboratory analysis results to deviate from the actual water quality. Utility Model Content

[0004] To address the issue mentioned above where varying water depths at different sampling points lead to the gradual deposition of suspended particulate matter and sedimentary impurities at the bottom due to gravity, resulting in significant differences in water composition at different depths, and substantial variations in turbidity, organic matter content, microbial distribution, and chemical concentration between surface and bottom water, it is crucial to avoid collecting unrepresentative water samples from a single depth or blindly sampling. This can cause subsequent laboratory analysis results to deviate from the actual water quality. Therefore, this invention provides a filtration device for water quality testing.

[0005] This utility model provides a filtration device for water quality testing, which adopts the following technical solution:

[0006] A water quality testing filtration device includes a filtration frame, a water pump fixedly connected to the bottom of the inner wall of the filtration frame, a telescopic tube fixedly connected to the top of the water pump, movable grooves on both the left and right sides of the filtration frame, a movable mechanism for adjusting the length of the telescopic tube slidably connected inside the movable grooves, and a groove on the right side of the filtration frame, with a rack fixedly connected inside the groove.

[0007] Optionally, in the above-mentioned water quality testing filtration device, the moving mechanism includes two moving blocks, which are slidably connected inside two moving slots respectively. An arc-shaped connecting strip is fixedly connected to the front side of the two moving blocks, and the bottom end of the telescopic tube passes through the lower side of the arc-shaped connecting strip.

[0008] The above technical solution facilitates the downward movement of the arc-shaped connecting strip when the moving block moves downward.

[0009] Optionally, in the above-mentioned water quality testing filtration device, the shape of the moving block and the shape of the inner wall of the moving groove are both T-shaped. An L-shaped groove is opened on the right side of the moving block. A Z-shaped block is slidably connected inside the L-shaped groove. A compression spring is fixedly connected to the front side of the horizontal block of the Z-shaped block. The front end of the compression spring is fixedly connected to the front side of the inner wall of the horizontal groove of the L-shaped groove.

[0010] The above technical solution makes it easy to define the position of the Z-shaped block using a compression spring.

[0011] Optionally, in the above-mentioned water quality testing filtration device, the upper and lower sides of the rear horizontal block of the Z-shaped block are provided with 30° bevel angles, the rear side of the rear horizontal block of the Z-shaped block slides with the inside of the rack, and the right side of the front horizontal block of the Z-shaped block is provided with a rectangular groove.

[0012] The above technical solution facilitates the rear horizontal block of the Z-shaped block with the beveled angle to fit with the side of the rack, making it easy to fix the height of the moving block and the arc-shaped connecting strip through the Z-shaped block and the rack.

[0013] Optionally, in the above-mentioned water quality testing filtration device, a placement frame is fixedly connected to the lower side of the front side of the filtration frame, the bottom of the placement frame is on the same horizontal plane as the bottom of the rack, the bottom end of the telescopic tube is slidably connected to the inside of the placement frame, and the spacing between the rack teeth adopts a standard size.

[0014] The above technical solution facilitates easy adjustment of the length of the arc-shaped connecting strip and the telescopic tube when they move downwards.

[0015] Optionally, in the above-mentioned water quality testing filtration device, a drain ball valve is fixedly inserted into the lower rear side of the filtration frame, and a frustum-shaped support is fixedly connected to the bottom of the filtration frame.

[0016] The above technical solution facilitates the increase of stability in supporting the filter frame by using a frustum-shaped support base.

[0017] Optionally, in the above-mentioned water quality testing filtration device, a fixed frame is fixedly connected to the top of the sealing cover of the filtration frame, and a guide roller is rotatably connected inside the fixed frame, with the side of the telescopic tube contacting the side of the guide roller.

[0018] The above technical solution facilitates stable sliding of the guide roller and telescopic tube.

[0019] In summary, this utility model has at least one of the following beneficial effects: by moving the Z-shaped block to the right and compressing the compression spring, the rear horizontal block of the Z-shaped block moves out of the rack, releasing the fixation of the two moving blocks and the arc-shaped connecting strip. Then, the arc-shaped connecting strip drives the telescopic tube to move down and insert it into the water. Next, referring to the size of the rack, the arc-shaped connecting strip drives the telescopic tube to move down to a suitable height, and the water pump is started, thereby filtering at different depths and ensuring the accuracy of water quality analysis.

[0020] When the rear horizontal block of the Z-shaped block moves forward at its tilting angle, it compresses the spring and releases its fixation to the rack. Then, it releases the fixation of the arc-shaped connecting strip, the telescopic tube, and the moving block. Next, the telescopic tube is moved down to the appropriate size through the arc-shaped connecting strip. Finally, the Z-shaped block is released, allowing it to move to the appropriate side of the rack through the spring. This limits and fixes the length of the telescopic tube inserted into the water, ensuring the stability of filtration of water at different depths. Attached Figure Description

[0027] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4An embodiment of this utility model provides a water quality testing filtration device, including a filtration frame 1, a water pump 2 fixedly connected to the bottom of the inner wall of the filtration frame 1, a telescopic tube 3 fixedly connected to the top of the water pump 2, movable grooves 4 on both the left and right sides of the filtration frame 1, a movable mechanism 5 for adjusting the length of the telescopic tube 3 slidably connected inside the movable grooves 4, and a groove 6 on the right side of the filtration frame 1, with a rack 7 fixedly connected inside the groove 6.

[0028] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 The moving mechanism 5 includes two moving blocks 501, which are slidably connected inside the two moving slots 4. An arc-shaped connecting strip 502 is fixedly connected to the front side of the two moving blocks 501. The bottom end of the telescopic tube 3 passes through the lower side of the arc-shaped connecting strip 502. When the moving blocks 501 move downward, they can drive the arc-shaped connecting strip 502 to move downward.

[0029] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 The shape of the movable block 501 and the inner wall of the movable groove 4 are both T-shaped. An L-shaped groove 503 is provided on the right side of the movable block 501. A Z-shaped block 504 is slidably connected inside the L-shaped groove 503. A compression spring 505 is fixedly connected to the front side of the horizontal block of the Z-shaped block 504. The front end of the compression spring 505 is fixedly connected to the front side of the inner wall of the horizontal groove of the L-shaped groove 503. The position of the Z-shaped block 504 can be conveniently limited by the compression spring 505.

[0030] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 The rear side of the Z-shaped block 504 has a 30° bevel angle on both the upper and lower sides. The rear side of the rear side of the Z-shaped block 504 slides with the inside of the rack 7. The right side of the front side of the Z-shaped block 504 has a rectangular groove 506. The rear side of the Z-shaped block 504 with the bevel angle can fit with the side of the rack 7, which makes it convenient to fix the height of the moving block 501 and the arc-shaped connecting strip 502 through the Z-shaped block 504 and the rack 7.

[0031] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4A placement frame 101 is fixedly connected to the lower front side of the filter frame 1. The bottom of the placement frame 101 is on the same horizontal plane as the bottom of the rack 7. The bottom end of the telescopic tube 3 is slidably connected inside the placement frame 101. The spacing between the toothed blocks of the rack 7 adopts a standard size. The standard size makes it easy to adjust the length of the arc-shaped connecting strip 502 and the telescopic tube 3 when they move downward.

[0032] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 A drain ball valve 102 is fixedly inserted into the lower rear side of the filter frame 1, and a frustum-shaped support 103 is fixedly connected to the bottom of the filter frame 1. The frustum-shaped support 103 can increase the stability of the filter frame 1.

[0033] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 and Figure 4 A fixed frame 104 is fixedly connected to the top of the sealing cover of the filter frame 1. A guide roller 105 is rotatably connected inside the fixed frame 104. The side of the telescopic tube 3 contacts the side of the guide roller 105, and the guide roller 105 facilitates the stable sliding of the telescopic tube 3.

[0034] Working principle: When using this water quality testing filtration device, first place the filtration device on the riverbank where the water quality needs to be tested. Then, move the Z-shaped block 504 to the right to compress the spring 505, causing the rear horizontal block of the Z-shaped block 504 to move out from inside the rack 7, thereby releasing the fixation of the two moving blocks 501 and the arc-shaped connecting strip 502. Next, the arc-shaped connecting strip 502 drives the telescopic tube 3 on its side to move downward and insert into the water. Then, referring to the standard dimensions of the rack 7, the arc-shaped connecting strip 502 drives the telescopic tube 3 to move downward to a suitable height in the water, and the water pump 2 is started, thereby enabling filtration at different depths and ensuring the accuracy of water quality analysis.

[0035] When the rear horizontal block of the Z-shaped block 504 moves forward with its inclined surface, it compresses the compression spring 505 and releases its fixation to the rack 7. Then, it releases the fixation between the arc-shaped connecting strip 502, the telescopic tube 3 and the moving block 501. Next, the arc-shaped connecting strip 502 drives the telescopic tube 3 to move downward to a suitable size. Finally, the Z-shaped block 504 is released, so that the Z-shaped block 504 moves into the teeth on the side of the rack 7 through the rebound force of the compression spring 505. This limits and fixes the length of the telescopic tube 3 inserted into the water, thereby ensuring the stability of filtration of water at different depths.

[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
