Description

Technical Field

[0001] This utility model relates to the field of waterway sediment detection technology, specifically a waterway sediment detection device. Background Technology

[0002] Waterways are important channels for water transportation. The accumulation and erosion of sediment can change the depth, width and direction of waterways, affecting the safe navigation of ships. In order to ensure that waterways always maintain suitable navigation conditions, it is necessary to accurately grasp the dynamic changes of sediment in waterways, which has promoted the development of waterway sediment detection technology.

[0003] By regularly monitoring the content, particle size distribution, and deposition patterns of sediment in waterways, key areas and degrees of sediment accumulation can be identified, providing accurate data for waterway dredging. This allows for the rational scheduling of dredging operations in terms of time, location, and scale, ensuring that the waterway depth meets the requirements for ship navigation and improving the waterway's navigability and safety.

[0004] The process involves transferring the collected water sample to a clean container, such as a beaker or graduated cylinder, then attaching filter paper or a filter membrane to the filter. The water sample is then slowly poured into the filter, allowing the water to pass through the filter paper or membrane, where sediment particles are trapped. The filter paper or membrane with sediment is then carefully removed and placed in an oven to dry.

[0005] Finally, remove the dried filter paper or membrane and place it in a desiccator to cool to room temperature. Then weigh it using a balance. Record the total weight of the dried filter paper or membrane and the sediment. Calculate the weight of the sediment, which is the total weight after drying minus the initial weight of the filter paper or membrane. Then, calculate the sediment content based on the volume of the water sample.

[0006] Regarding the existing related technologies, the inventor believes that the following defects exist: when the water sample is filtered, the filter paper containing mud and sand is easily spilled when the staff removes it. At the same time, during the movement of the filter paper, the water remaining on the filter paper can easily drip down and contaminate the workbench. Utility Model Content

[0007] To address the existing technical problems of sediment spillage when workers remove filter paper containing sediment, and water residue on the filter paper dripping and contaminating the workbench during movement, this invention provides a waterway sediment detection device.

[0008] This utility model is achieved using the following technical solution: a waterway sediment detection device, comprising a base and a fixing plate. A collection box is disposed at the top center of the base, and the collection box is located at the bottom of the fixing plate. Multiple fixing pipes are fixedly connected to the top of the fixing plate. A filter dish is placed on the top of each fixing pipe, and filter paper is disposed inside the filter dish. Multiple drainage troughs are machined at the bottom of each of the fixing pipes. A handle is disposed at one end of the fixing plate, and a rotating shaft is fixedly connected to one end of the handle. The rotating shaft is rotatably connected to the inside of the fixing plate. Multiple valves are fixedly connected to one end of the rotating shaft, and the multiple valves are movably connected to the inside of the multiple drainage troughs.

[0009] Preferably, one end of each of the two valves is fixedly connected to a connecting rod, which is rotatably connected inside the fixed plate.

[0010] Preferably, a baffle is fixedly connected to one side of the inner wall of the drain tank, and the top of the baffle is in contact with one end of the valve.

[0011] Preferably, one end of the handle is movably connected to a limiting pin, and one end of the fixing plate is machined with two limiting holes, with one end of the limiting pin being inserted into the inside of the limiting hole.

[0012] Preferably, one end of the limiting pin is fixedly connected to a pull block, and a return spring is provided on the inner side of the pull block. One end of the return spring is fixedly connected to the inner side of the handle, and the other end of the return spring is fixedly connected to one side of the baffle.

[0013] Preferably, the top perimeter is fixedly connected with multiple support columns, the bottom perimeter of the fixing plate is machined with multiple grooves, and the top of the support columns is plugged into the inside of the grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In use, this invention involves slowly pouring the collected water sample into the filter dish, allowing the water to pass through the filter paper. The filter paper traps the sediment particles on its surface. Then, turning the handle causes the rotating shaft and valve to rotate, sealing the lower water tank. Finally, moving the fixing plate moves multiple fixing tubes and the filter paper into an oven for drying, thus preventing sediment spillage and water droplets from contaminating the filter paper.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example 1: Please refer to Figure 1 - Figure 5 This embodiment of a waterway sediment detection device includes a base 1 and a fixing plate 2. A collection box 3 is set at the top center of the base 1 and is located at the bottom of the fixing plate 2. Multiple fixing pipes 4 are fixedly connected to the top of the fixing plate 2. A filter dish 5 is placed on the top of the fixing pipe 4 and filter paper 9 is arranged inside the filter dish 5. Multiple drainage troughs 6 are processed at the bottom of the multiple fixing pipes 4. A handle 11 is set at one end of the fixing plate 2. A rotating shaft 12 is fixedly connected to one end of the handle 11. The rotating shaft 12 is rotatably connected to the inside of the fixing plate 2. Multiple valves 13 are fixedly connected to one end of the rotating shaft 12. The multiple valves 13 are movably connected to the inside of the multiple drainage troughs 6 respectively.

[0024] When it is necessary to filter sediment, the collected water sample is slowly poured from the standard measuring cylinder into the filter dish 5, so that the water passes through the filter paper 9. The filter paper 9 traps the sediment particles on the surface. The filtered water will pass through the drain trough 6 to the inside of the collection box 3 for collection. By pouring multiple sets of water samples into the inside of multiple filter dishes 5, it is convenient to measure and calculate multiple sets of data at the same time.

[0025] Secondly, turn the handle 11, which will drive the rotating shaft 12 to rotate. The rotating shaft 12 will drive multiple valves 13 to rotate, so that the multiple valves 13 rotate inside the multiple drain tanks 6 respectively, thereby moving the drain tanks 6 to a horizontal state and sealing the interior of the drain tanks 6. Finally, move the fixing plate 2, which will drive multiple fixing tubes 4 and filter dishes 5 into the drying oven to dry, thereby avoiding the leakage of mud and sand on the filter paper 9 and water droplets causing pollution.

[0026] Finally, remove the dried filter paper 9 from the filter dish 5, place it in a desiccator to cool to room temperature, then weigh it using a balance, record the total weight of the dried filter paper 9 and the sediment, calculate the weight of the sediment, that is, the total weight after drying minus the initial weight of the filter paper or filter membrane, and then calculate the sediment content based on the volume of the water sample.

[0027] Furthermore, one end of each of the two valves 13 is fixedly connected to a connecting rod 14, which is rotatably connected inside the fixed plate 2. The two valves 13 are connected together by the connecting rod 14, so that the rotation of the shaft 12 can drive multiple valves 13 to rotate simultaneously, thereby controlling the closure inside the lower water tank 6 at the same time.

[0028] Furthermore, a baffle 15 is fixedly connected to one side of the inner wall of the drain tank 6. The top of the baffle 15 is in contact with one end of the valve 13. By providing the baffle 15, the movement of the valve 13 will be limited.

[0029] Furthermore, one end of the handle 11 is movably connected to a limit pin 16, and one end of the fixing plate 2 is machined with two limit holes 10. One end of the limit pin 16 is inserted into the inside of the limit hole 10. By setting the limit pin 16, when one end of the limit pin 16 is inserted into the inside of the limit hole 10, the limit pin 16 will limit the movement of the handle 11 and prevent the handle 11 from rotating.

[0030] Furthermore, one end of the limiting pin 16 is fixedly connected to a pull block 18, and a return spring 17 is provided on the inner side of the pull block 18. One end of the return spring 17 is fixedly connected to the inner side of the handle 11, and the other end of the return spring 17 is fixedly connected to one side of the baffle 15.

[0031] The invention includes a return spring 17. When the pull block 18 is pulled, the pull block 18 will cause one end of the limit pin 16 to disengage from the interior of the limit hole 10. At the same time, the pull block 18 will squeeze the return spring 17, which will be compressed. When the pull block 18 is released, the return spring 17 will return to its original position and extend. The return spring 17 will then cause the pull block 18 and the limit pin 16 to move, so that one end of the limit pin 16 is inserted into the interior of the limit hole 10.

[0032] Furthermore, multiple support columns 7 are fixedly connected around the top perimeter of the fixed plate 2, and multiple grooves 8 are machined around the bottom perimeter of the fixed plate 2. The top of the support columns 7 is inserted into the groove 8. By setting the support columns 7 and inserting the top of the support columns 7 into the groove 8 at the bottom of the fixed plate 2, the fixed plate 2 can be placed stably on the top of the support columns 7, and the fixed plate 2 can be easily moved.

[0033] Working principle: The collected water sample is slowly poured into the filter dish 5, allowing the water to pass through the filter paper 9. The filter paper 9 traps the sediment particles on its surface. Then, the handle 11 is turned, which drives the rotating shaft 12 and valve 13 to rotate. The valve 13 rotates inside the lower water tank 6 to seal the lower water tank 6. Finally, the fixing plate 2 is moved, which drives multiple fixing tubes 4 and the filter paper 9 into the drying oven to dry them. This prevents the sediment on the filter paper 9 from spilling and water from dripping and causing pollution.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
