Description

Technical Field

[0001] This invention relates to the field of water conservancy and hydrology technology, and more specifically, to a water conservancy and hydrology sediment content detection device. Background Technology

[0002] Water conservancy and hydrology generally refers to the water conservancy industry, which belongs to environmental protection engineering. It studies and solves the process of water cycle, mainly by detecting sediments in rivers and reservoirs, pollution in river water, and urban drainage. River sediment content is one of the important hydrological parameters. Monitoring river sediment content is of great significance for projects such as soil and water conservation, industrial and agricultural water use, water conservancy and hydropower construction, water resource development and utilization, and hydrological forecasting. Therefore, it is necessary to regularly detect the sediment content in water flow.

[0003] When testing for sand content, the sample water is placed in a beaker and heated to evaporate. Finally, the remaining mud and sand are weighed. Existing equipment cannot heat and evaporate multiple beakers simultaneously, which affects the accuracy of the test. In addition, during the evaporation process, the mud and sand in the sample water tend to adhere to the inner wall of the beaker, making it difficult to pour out. Furthermore, after evaporation, the beaker becomes too hot to be removed in time, which affects the efficiency of the test.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

Multiple sets of samples can be heated at one time, which is convenient for comparison and improves the detection accuracy.

[0037] Example 3

[0038] like Figure 1-9As shown, the device includes a housing 1, a lid 2 at the top of the housing 1, a placement plate 3 inside the housing 1, several evenly distributed placement slots 4 at the top of the placement plate 3, each containing a matching beaker 5, and a clamping assembly matching the beaker 5 within the placement plate 3. A horizontally arranged conveying pipe 6 is located at the bottom of the placement plate 3 within the housing 1, connected to the housing 1 via a connecting block 20.

Lead screw 23 is threadedly connected to movable sleeve 24, and movable sleeve 24 is guided and limited by guide block 27 and guide groove 28. When lead screw 23 rotates, it drives movable sleeve 24 to move downward, which in turn drives lifting plate 9 to move downward. Lifting plate 9 drives anti-overflow cover 10 to move downward until it seals the edge of the top opening of beaker 5, preventing water from overflowing from beaker 5 when boiling, and also preventing the mixing of steam in different beakers from affecting the detection accuracy. The steam generated during the heating process flows through telescopic hose 14 to the vent 13 and is discharged.

By setting up lifting plate, anti-overflow cover and lifting assembly, the opening edge can be sealed when heating beaker to prevent water from boiling and overflowing from beaker. By setting up U-shaped scraper and linkage assembly, the inner wall of beaker can be rotated and scraped during heating to prevent mud and sand from adhering to the inner wall of beaker and difficult to remove. At the same time, the linkage assembly can drive multiple sets of U-shaped scrapers to operate synchronously to improve the scraping efficiency of multiple beakers.

[0040] Example 4

[0041] like Figure 1-9As shown, the device includes a housing 1, a lid 2 at the top of the housing 1, a placement plate 3 inside the housing 1, several evenly distributed placement slots 4 at the top of the placement plate 3, each containing a matching beaker 5, and a clamping assembly matching the beaker 5 within the placement plate 3.

The lid... 2 is provided with a lifting plate 9, which is connected to the lid 2 via a lifting assembly. On one side of the lifting plate 9, there are several evenly distributed anti-overflow covers 10 that match the beaker 5. On the side of the lifting plate 9 away from the anti-overflow covers 10, there is a linkage box 11. The linkage box 11 is connected to the lifting plate 9 and the anti-overflow covers 10. On the side of the anti-overflow covers 10 away from the linkage box 11, there is a U-shaped scraper 12 that matches the beaker 5. The U-shaped scraper 12 is connected to the linkage box 11 via a linkage assembly. On one side of the lid 2, there are several evenly distributed air outlets 13.

A semiconductor cooling plate 39 is installed in the mounting holes 38. The cooling surface of the semiconductor cooling plate 39 is located inside the fan box 34. The heating surface of the semiconductor cooling plate 39 is provided with several evenly distributed heat sinks 40. An air inlet 41 is located at the bottom of the fan box 34. A matching dustproof net 42 is installed in the air inlet 41.

[0042] After beaker 5 is heated, fan 36 is started. At this time, the cooling surface in semiconductor cooling plate 39 cools the air inside the air box 34. Fan 36 blows cold air towards beaker 5, making beaker 5 cool down quickly. During this process, external air enters the air box 34 after being filtered by dust screen 42 to prevent dust from entering the box 1. After cooling is complete, the box cover 2 is opened and beaker 5 is taken out. Then the mud and sand in beaker 5 are weighed and tested. By setting the cooling component, the beaker can be cooled down quickly after heating, making it convenient for personnel to take it out without waiting, improving the testing efficiency, and also preventing the beaker temperature from reaching the point of accidental injury to personnel.

[0043] In summary, by utilizing the above-mentioned technical solutions of the present invention, multiple sets of placement slots and clamping components can be set on the placement plate to clamp and fix multiple sets of beakers for heating simultaneously. This allows for the simultaneous heating of multiple samples, facilitating comparison and improving detection accuracy. By setting a cooling component, the beakers can be quickly cooled after heating, making them easy to remove without waiting, thus improving detection efficiency and preventing accidental injury from high beaker temperatures, thereby enhancing safety. By setting a lifting plate, an anti-overflow cover, and a lifting component, the opening edge of the beaker can be sealed during heating to prevent boiling water from overflowing from the beaker. By setting a U-shaped scraper and a linkage component, the inner wall of the beaker can be rotated and scraped during heating to prevent mud and sand from adhering to the inner wall of the beaker and making it difficult to remove. At the same time, the linkage component can drive multiple sets of U-shaped scrapers to operate synchronously, improving the scraping efficiency of multiple sets of beakers.
