Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a rapid sampling device for water quality detection. Background Art

[0002] Water quality testing is an extremely critical and complex task. It covers the comprehensive, systematic and accurate determination and analysis of chemical, physical and biological indicators of various water bodies. This work is of great significance to environmental protection, water resources management, public health and industrial production. In the process of water quality testing, it is first necessary to collect representative samples from the water body to be tested to ensure that the samples can accurately reflect the actual water body conditions. After the samples are collected, a series of standardized laboratory test methods are used to measure the turbidity, color, pH value, dissolved oxygen, conductivity, total hardness, ammonia nitrogen, nitrate, nitrite, total phosphorus, total nitrogen, heavy metal ions (such as lead, mercury, cadmium, chromium, etc.), microbial content and many other indicators of the water samples. Among them, chemical oxygen demand (COD) and biochemical oxygen demand (BOD) are important parameters for measuring the degree of organic pollution in water bodies; and microbial detection is related to the safety of drinking water.

[0003] The rapid sampling device used for water quality testing is an important tool in the field of modern environmental protection technology and water quality monitoring. It is designed to collect representative samples from various water bodies efficiently, accurately and pollution-free. The rapid sampling device is usually made of high-quality materials to ensure that no secondary pollution is generated when it comes into contact with water bodies. It also has corrosion resistance and durability. It has a compact structure and is easy to carry and operate. It is especially suitable for on-site sampling work in the wild, rivers, lakes, reservoirs, groundwater wells and industrial wastewater outlets.

[0004] In modern water quality testing and sampling technology, a motor is used to drive the screw, so that the upper slider drives the collection bottle at the bottom to extend, and the eccentric block at the bottom drives the collection bottle to achieve vertical adjustment, so that the collection bottle can flexibly penetrate into different depths of the lake to collect water samples. However, in actual application, due to the complex and changeable lake environment, the physical and chemical properties of water bodies in different areas may vary significantly, and the synchronous extension and descent characteristics of the screw during movement mean that it may face certain limitations when it comes to precise sampling at specific depths or narrow areas. For example, when there are steep slopes or irregular potholes at the bottom of the lake, or multiple sampling is required at a specific depth layer, a single synchronous motion mode may not be able to achieve refined sampling of the target area.

[0005] Therefore, it is necessary to provide a new rapid sampling device for water quality detection to solve the above technical problems. Utility Model Content

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 , Figure 1 This is a schematic diagram of the overall structure of the rapid sampling device for water quality testing provided by the utility model; Figure 2 A schematic cross-sectional view of a rapid sampling device for water quality testing provided by the utility model; Figure 3 for Figure 2 An enlarged schematic diagram of A is shown; Figure 4 A schematic diagram of the structure of the connecting piece provided by the utility model; Figure 5 This is a schematic diagram of the structure of the connected inner disk provided by the utility model.

[0024] In the specific implementation process, Figures 1 to 5As shown, the rapid sampling device for water quality detection includes a fixed base 1, a motor 3 and a fixed bracket 7 are installed on the top of the fixed base 1 in sequence, an output end of the motor 3 is fixedly connected to a shaft rod 1 4, a shaft rod 2 8 and a shaft rod 4 20 are horizontally movable and a shaft rod 3 13 is vertically movable through the fixed bracket 7, and a synchronous belt 19 is arranged on the outer surface of the shaft rod 1 4 and the shaft rod 4 20, a connecting piece is arranged on the outer surface of the shaft rod 1 4 and the shaft rod 2 8, an end of the shaft rod 2 8 away from the shaft rod 1 4 is fixedly connected to a bevel gear 1 12, an outer surface of the shaft rod 3 13 is fixedly connected to a bevel gear 2 14, and the bevel gear 1 12 is meshed with the bevel gear 2 14, a sampling piece is arranged on the outer surface of the shaft rod 3 13 and the shaft rod 4 20, and a screw area is arranged in the middle of the shaft rod 3 13 and the shaft rod 4 20;

[0025] The connecting member includes a connecting outer disk 5 fixedly connected to the outer surface of the shaft rod 1 4 and a connecting inner disk 9 fixedly connected to the outer surface of the shaft rod 2 8, and the connecting inner disk 9 is located inside the connecting outer disk 5, and protruding blocks 10 are movably connected at both ends of the connecting inner disk 9, and a spring 11 is arranged between the connecting inner disk 9 and the protruding block 10, and a plurality of inner bevel teeth 6 are arranged at equal intervals on the inner side wall of the connecting outer disk 5, and the outer surface of the protruding block 10 is in contact with the inner wall of the plurality of inner bevel teeth 6.

[0026] The sampling member includes a sliding block 15 movably connected to the screw rod area of ​​the shaft rod 3 13 and a sliding block 2 16 movably connected to the screw rod area of ​​the shaft rod 4 20. The outer surfaces of the sliding block 15 and the sliding block 2 16 are provided with a connecting block 17. The bottom of the connecting block 17 is threadedly connected with a collecting bottle 18 for sampling.

[0027] The four corners of the bottom of the fixed base 1 are movably connected with universal wheels 2, ensuring that the base is stable and reliable when it needs to be stationary, and can easily and freely perform 360-degree all-round turns when it needs to be moved or adjusted, greatly improving the maneuverability and flexibility of the product.

[0028] The working principle provided by the utility model is as follows: when the utility model is implemented, the shaft rod 14 of its output shaft is driven to rotate at a high speed by starting the motor 3, thereby driving the connecting outer disk 5 installed on the outer surface closely connected to it to move synchronously. When the connecting outer disk 5 rotates, the protrusion block 10 is driven to contract, so as not to drive the connecting inner disk 9 to move. At the same time, the shaft rod 14 drives the shaft rod 4 20 at the top to rotate through the synchronous belt 19. A screw rod area is embedded in the middle of the shaft rod 4 20. As the shaft rod 4 20 rotates, the thread on the screw rod drives the sliding block 2 16 to slide precisely along the screw rod direction, which can realize the effective telescopic adjustment of the connecting block 17, so that the collecting bottle 18 carried at the bottom of the connecting block 17 can perform sample collection operations in different areas and different ranges of space according to needs.

[0029] When it is necessary to change the collection depth or to obtain samples at different underwater levels, the motor 3 can be controlled to reverse and run. The raised block 10 on the connecting outer disk 5 is in an expanded state under the action of the elastic potential energy of the spring 11, thereby starting to drive the originally stationary connecting inner disk 9 to rotate synchronously. The connecting inner disk 9 is connected to the bevel gear 1 12 through the shaft rod 2 8. With the help of the gear meshing principle, the bevel gear 1 12 drives the matching bevel gear 2 14 to rotate together, and the bevel gear 2 14 is tightly combined with the shaft rod 3 13, so the shaft rod 3 13 will also rotate with it and produce a displacement effect in its own screw section. Through the rotational movement of the screw on the shaft rod 3 13, the connecting block 17 below it can also be accurately telescoped and adjusted, so that the collecting bottle 18 at the bottom can be freely raised and lowered in waters of different depths, thereby realizing the effective collection and detection of samples at the target depth.
