Description

Technical Field

[0001] The utility model relates to the technical field of drinking water filtration, in particular to a portable self-tapping rod for measuring the thickness of filter media. Background Art

[0002] In the treatment of drinking water, the filtration process is widely used. The process facility responsible for filtration is the filter tank, and the thickness of the filter media in the filter tank has an important impact on the filtration effect. The commonly used filter media in the filter tank is quartz sand. During the daily use of the filter tank, the quartz sand is subject to wear and sand leakage. Therefore, it is often necessary to measure the thickness of the filter media in the filter tank. When the thickness deviates too much from the design value, sand needs to be replenished.

[0003] At present, the measurement of the thickness of the filter media in the filter tank mainly uses a measuring plate, that is, a long plate with scales. The long plate is leaned against the edge of the filter tank, and the height from the surface of the filter media to the upper part of the filter tank is measured. Then, the thickness of the filter media is calculated according to the elevation marked on the design drawing. The main disadvantages of the above technology are that since this measurement method indirectly measures the thickness of the filter media, that is, uses the marked height from the bottom to the upper part of the filter tank on the drawing, subtracts the height from the surface of the filter media to the upper part of the filter tank to obtain the thickness of the filter media; this method often results in inaccurate measurement of the thickness of the filter media due to the tiles on the structure or non-standard construction, and the used measuring plate cannot be telescoped, making it difficult to store and carry. Therefore, this application proposes a portable self-tapping rod for measuring the thickness of filter media. Summary of the Utility Model

[0029] Embodiment 1:

[0030] Please refer to Figures 1-5 , a portable self-tapping rod for measuring the thickness of filter media, includes a first connecting rod 1 and a second connecting rod 2. First flat heads 3 are provided at both the upper and lower ends of the first connecting rod 1. A first stud 4 is fixed at the upper end of the first connecting rod 1 and above the first flat head 3. A first screw hole 6 is provided inside the first flat head 3 at the lower end of the first connecting rod 1. A drill bit adapter 8 and a manual wheel 9 are respectively provided at the upper end of the first connecting rod 1. The drill bit adapter 8 is located outside the first stud 4 and is threadedly connected to the first stud 4. The bottom end of the drill bit adapter 8 is in contact with the first connecting rod 1. The manual wheel 9 is located outside the first flat head 3 at the upper end of the first connecting rod 1. A flat opening 10 is provided at the center inside the manual wheel 9. The inner side of the flat opening 10 is in contact with the outer side of the first flat head 3, so that the manual wheel 9 is limited between the first connecting rod 1 and the drill bit adapter 8;

[0031] The upper and lower ends of the second connecting rod 2 are both provided with second flat heads 12. At the upper end of the second connecting rod 2 and above the second flat head 12, a second stud 13 is fixed. Inside the second flat head 12 at the lower end of the second connecting rod 2, a second screw hole 15 is opened. Rubber sliders 17 and baffles 18 are respectively sleeved on the outer side of the second connecting rod 2. Scale lines 11 are arranged on the outer side of the second connecting rod 2 and inside the rubber sliders 17 and the baffles 18. There is a certain friction between the rubber sliders 17 and the second connecting rod 2, so that after the rubber sliders 17 move on the outer side of the second connecting rod 2 and without support, they can stay at the original position to record and measure the height.

[0032] A double - helix drill rod 19 is provided at the lower end of the second connecting rod 2. The upper end of the double - helix drill rod 19 is fixed with a third stud 20. The third stud 20 is located inside the second screw hole 15 and is thread - connected with the second screw hole 15. Drilling into the filter material with the double - helix drill rod 19 has a faster drilling speed and a smaller pulling - out resistance.

[0033] The first connecting rod 1 and the second connecting rod 2 are both made of stainless steel. The lengths of the first connecting rod 1 and the second connecting rod 2 are both 1m, the diameters of the first connecting rod 1 and the second connecting rod 2 are both 12mm, the sizes of the first flat head 3, the second flat head 12 and the flat opening 10 are all 10mm, the diameters of the first stud 4, the second stud 13, the first screw hole 6 and the second screw hole 15 are all 8mm, the diameter of the baffle 18 is about 20cm, and the baffle 18 is made of PP plastic material and has a certain toughness.

[0034] Example 2:

[0035] The portable self - tapping rod for measuring the thickness of filter material provided in Example 1 is further optimized. Specifically, as Figures 3-5 shown, the first stud 4 and the first screw hole 6 and the second screw hole 15, and the second stud 13 and the first screw hole 6 and the second screw hole 15 are all thread - adapted. Furthermore, the structures of the first connecting rod 1 and the second connecting rod 2 are the same. Therefore, rods can be flexibly added and extended to increase the overall length of the rod body according to the measurement requirements.

[0036] A first shallow socket 5 is opened inside the first stud 4. Inside the first connecting rod 1 and outside the first screw hole 6, a first thread port 7 is opened. The first screw hole 6 and the first thread port 7 are connected. A second shallow socket 14 is opened inside the second stud 13. Inside the second connecting rod 2 and outside the second screw hole 15, a second thread port 16 is opened. The second screw hole 15 and the second thread port 16 are connected. Tip set screws can be installed inside the first thread port 7 and the second thread port 16. One end of each tip set screw fits with the first shallow socket 5 and the second shallow socket 14 respectively, making the connection between the first connecting rod 1 and the second connecting rod 2 tighter, so that the rod body is not easy to separate and disassemble when rotating.

[0037] The usage process of the portable self-tapping rod for measuring the thickness of filter media provided by the utility model is as follows: After the first connecting rod 1 and the second connecting rod 2 are installed by the threaded connection between the second stud 13 and the first threaded hole 6, the tip set screw is installed into the first thread port 7 at the lower end of the first connecting rod 1, so that one end of the tip set screw fits with the second shallow socket 14, thereby making the connection between the first connecting rod 1 and the second connecting rod 2 more tight. The manual wheel disc 9 is sleeved outside the first flat head 3 at the upper end of the first connecting rod 1 through the flat opening 10, and then the drill bit adapter 8 is threadedly connected to the outside of the first stud 4. After the bottom end of the drill bit adapter 8 fits with the first connecting rod 1, the drill bit adapter 8 is fixed and the manual wheel disc 9 is limited between the first connecting rod 1 and the drill bit adapter 8, completing the assembly among the drill bit adapter 8, the manual wheel disc 9 and the first connecting rod 1;

[0038] After the double helix drill rod 19 is installed and fixed to the second connecting rod 2 by the threaded connection between the third stud 20 and the second threaded hole 15, the measurement work begins. First, the drill bit adapter 8 is externally connected to a drill, and the bottom end of the double helix drill rod 19 is perpendicular to the surface of the filter media. Then, the drill drives the rod body to rotate, and the double helix drill rod 19 quickly drills into the filter media. At this time, the baffle 18 moves upward under the resistance of the filter media surface, driving the rubber slider 17 to move upward. When the bottom end of the double helix drill rod 19 fits with the bottom of the filter tank, it means that the rod body touches the bottom. Then, the rod body is pulled out by rotating the wheel disc. At this time, the position where the rubber slider 17 stays, together with the scale line 11, facilitates directly reading out the thickness value of the filter media, realizing obtaining the actual thickness of the filter media. After the measurement is completed, the whole is disassembled to achieve portability.
