Description

Technical Field

[0001] This application relates to the field of environmental testing technology, and in particular to a wastewater extraction device for testing. Background Technology

[0002] In environmental monitoring, accurate extraction of wastewater is crucial. As environmental protection receives increasing attention and the environmental monitoring market continues to expand, the demand for wastewater extraction equipment is also increasing. However, existing technologies have many problems.

[0003] A search revealed Chinese Patent Publication No. CN119124749A, which discloses a wastewater extraction device for environmental testing. The device includes an extraction device body, a receiving and dispensing mechanism at the top of the extraction device body, an extraction mechanism at the bottom of the receiving and dispensing mechanism, and a discharge mechanism on the surface of the extraction mechanism. In this wastewater extraction device for environmental testing, because the pressure inside the housing is greater than the external pressure, the wastewater will pass through the cylinder and the feed pipe into the interior of the placement box, thereby completing the purpose of wastewater extraction.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following shortcomings: Although the patent can extract wastewater from different locations and achieve the purpose of detecting wastewater at different depths, it is insufficient in terms of portability and flexibility. Because it needs to adapt to different water depths and has a certain length, it is inconvenient to carry. Furthermore, the distance between each extraction mechanism cannot be adjusted, making it difficult to meet the flexible requirements for different sampling layer spacing in actual use, thus limiting the detection capabilities. However, this patented technology does not provide a solution to this problem. Summary of the Invention

[0005] To address the problems mentioned in the background section, this application provides a wastewater extraction device for detection.

[0006] This application provides a wastewater extraction device for detection, employing the following technical solution: It includes a base, with a vertical plate fixedly connected to the upper end of the base. A control panel is fixedly connected to the lower left end of the vertical plate. Sliding grooves are formed at both the front and right ends of the vertical plate. A first drive motor is fixedly connected to the middle of the upper end of the vertical plate. The output end of the first drive motor passes through the vertical plate and is fixedly connected to a long screw. A cantilever arm is threaded onto the outer surface of the long screw. A limit slider is fixedly connected to the rear right end of the cantilever arm. A connecting frame is fixedly connected to the front lower end of the cantilever arm. A second drive motor is fixedly connected to the rear end of the connecting frame. The output end of the second drive motor passes through the connecting frame and is fixedly connected to a rope roller. A rope body is wound around the outer surface of the rope roller.

[0007] Optionally, a six-bar frame is connected to the lower end of the connecting seat. An outer ring frame is fixedly connected to the outer side of the six-bar frame. Six connecting rods are fixedly connected to the lower end of the six-bar frame. A conical weight is fixedly connected to the lower end of the connecting rods. Through holes are opened around the upper end of the six-bar frame. Long rods are inserted into each of the six through holes. Nuts are threaded onto the upper part of the outer surface of the long rods. A limit ring is fixedly connected to the upper part of the outer surface of the long rods, and the limit ring is located directly below the nut. A connecting block is fixedly connected to the bottom of the long rods. A sampling cylinder is fixedly connected to the outer side of the connecting block. A mesh cover is provided on the top of the sampling cylinder.

[0008] Optionally, the limiting slider is slidably connected in the groove at the right end of the upright plate, the front end of the cantilever arm is slidably connected in the groove at the front end of the upright plate, and the cantilever arm is horizontally distributed, the long screw is vertically distributed, and the lower end of the long screw is movably connected to the middle of the upper end of the base.

[0009] Optionally, the six-bar frame is arranged in a regular hexagonal three-dimensional distribution, the six connecting rods are arranged in a ring at equal intervals around the central axis of the six-bar frame, and the conical block weight is in the shape of a cone with the tip pointing downwards.

[0010] Optionally, the outer ring frame has a ring structure, and the outer ring frame is vertically fixed to the outer side wall of the six-bar frame. The six long bars correspond one-to-one with the six through holes and are vertically connected.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This invention utilizes a sliding groove on the upright plate, a long screw, and a threaded connection structure with the cantilever arm. Driven by a first drive motor, the cantilever arm can move smoothly up and down through the sliding connection at the front end and the sliding of the right end limiting slider, allowing for flexible height adjustment. Simultaneously, the long rod inside the insertion hole at the upper end of the six-bar frame can be adjusted and fixed in height via a nut and a limiting ring, driving the sampling cylinder to flexibly change position. This allows the spacing between each sampling component to be adjusted according to actual needs, meeting the detection requirements for different sampling layer spacings.

[0015] This utility model forms a stable support system through the base and the upright plate. The sliding of the cantilever arm is ensured by the double limiting of the slide groove and the limiting slider. The six-bar frame adopts a regular hexagonal three-dimensional distribution and is combined with the outer ring frame to improve the structural strength. The conical shape of the conical block weight reduces the sinking resistance and ensures that the sampling component sinks smoothly into the wastewater. In addition, the net cover on the top of the sampling tube can block large impurities. Combined with the stable connection of each component, the sampling purity and the reliability of equipment operation are greatly improved. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a wastewater extraction device for detection. For example... Figure 1As shown, the device includes a base 1, with a vertical plate 2 fixedly connected to the upper end of the base 1. The base 1 provides stable support for the entire device, ensuring that the device will not easily shake during operation and improving the overall stability of the device. A control panel 19 is fixedly connected to the lower left end of the vertical plate 2. The control panel 19 can achieve precise control of the device's operating parameters, making it convenient for operators to operate according to actual extraction needs. The control panel 19 is electrically connected to the first drive motor 4 and the second drive motor 10 via wires, and the control panel 19 is located in the middle of the lower left end of the vertical plate 2. This position makes it easy for operators to reach during operation, improving the convenience of operation. Slide grooves 5 are opened at the front and right ends of the vertical plate 2. The slide grooves 5 provide guidance for the sliding of related components, ensuring the smoothness of the component sliding process.

[0023] Please see Figure 1 A first drive motor 4 is fixedly connected to the upper middle part of the upright plate 2. The first drive motor 4 serves as a power source, providing sufficient power for the rotation of the long screw 18. The output end of the first drive motor 4 passes through the upright plate 2 and is fixedly connected to the long screw 18. The long screw 18 is vertically distributed, and its lower end is movably connected to the upper middle part of the base 1. This connection method makes the long screw 18 more flexible when rotating and reduces frictional resistance. A cantilever arm 8 is threadedly connected to the outer surface of the long screw 18. The rotation of the long screw 18 can drive the cantilever arm 8 to move up and down, thereby adjusting the height position of the cantilever arm 8. The front end of the cantilever arm 8 is slidably connected to the groove 5 at the front end of the vertical plate 2, and the cantilever arm 8 is horizontally distributed. The groove 5 limits and guides the sliding of the cantilever arm 8, ensuring that the cantilever arm 8 will not deviate during the up and down movement. The right rear end of the cantilever arm 8 is fixedly connected to the limiting slider 7, which is slidably connected to the groove 5 at the right end of the vertical plate 2. The limiting slider 7 further enhances the stability of the cantilever arm 8 during sliding and prevents the cantilever arm 8 from shaking. The lower front end of the cantilever arm 8 is fixedly connected to the connecting plate frame 9, which provides a mounting carrier for components such as the second drive motor 10.

[0024] Please see Figure 1 and Figure 2A second drive motor 10 is fixedly connected to the rear end of the connecting plate frame 9. The second drive motor 10 can drive the rope roller 11 to rotate. The output end of the second drive motor 10 passes through the connecting plate frame 9 and is fixedly connected to the rope roller 11. The rope roller 11 can realize the winding and unwinding of the rope body 12, thereby adjusting the length of the rope body 12. The rope body 12 is wound and connected to the outer surface of the rope roller 11. The rope body 12 plays the role of connection and load-bearing, and can suspend components such as the connecting seat 20. One end of the rope body 12 is fixedly connected to a threaded joint 13. The threaded connection between the threaded joint 13 and the connecting seat 20 facilitates the installation and disassembly of both, and makes it convenient to replace or repair the components. The connecting seat 20 is threadedly connected to the outer surface of the threaded joint 13.

[0025] Please see Figure 3 and Figure 4The lower end of the connecting seat 20 is connected to a six-bar frame 21. The six-bar frame 21 provides a stable support structure for components such as the outer ring frame 14 and connecting rods 15. The six-bar frame 21 is a regular hexagonal three-dimensional distribution. The regular hexagonal structure has good stability and symmetry, which can make the force on each component uniform. The six connecting rods 15 are distributed in a ring at equal intervals around the central axis of the six-bar frame 21. This distribution method ensures that the conical block weight 16 is subjected to uniform force. The outer ring frame 14 is fixedly connected to the outer side of the six-bar frame 21. The outer ring frame 14 can enhance the overall structural strength of the six-bar frame 21. The outer ring frame 14 is a ring structure, and the outer ring frame 14 and the six-bar frame 21 are connected in a ring. The outer wall of the rod frame 21 is vertically fixed, which further improves the stability of the structure. Six connecting rods 15 are fixedly connected to the lower end of the six-bar frame 21. These connecting rods 15 connect the six-bar frame 21 and the conical weight 16. The lower ends of the connecting rods 15 are all fixedly connected to the conical weight 16. The conical weight 16, using its own weight, makes it easier for the sampling component to sink into the wastewater, facilitating wastewater extraction. The conical weight 16 has a cone shape with the tip pointing downwards, which reduces resistance when sinking into the wastewater. The upper end of the six-bar frame 21 has through holes 22 around its perimeter, through which the long rods 24 pass. The device provides a channel, with six insertion holes 22 through which long rods 24 are inserted one by one. The long rods 24 can drive the sampling cylinder 17 to move up and down. The six long rods 24 correspond one-to-one with the six insertion holes 22 and are perpendicularly inserted, ensuring the verticality of the long rods 24's movement. A nut 25 is threaded onto the upper outer surface of the long rods 24, fixing their position and preventing displacement during use. A limit ring 6 is fixedly connected to the upper outer surface of the long rods 24, located directly below the nut 25, limiting the nut 25 and preventing it from moving. 5. Over-tightening may damage components. A connecting block 3 is fixedly connected to the bottom of the long rod 24. The connecting block 3 connects the long rod 24 and the sampling cylinder 17. The sampling cylinder 17 is fixedly connected to the outside of the connecting block 3. The sampling cylinder 17 is a container for holding the extracted wastewater. The sampling cylinder 17 has a cylindrical structure, which is easy to process and clean, and can ensure a certain volume. The screen cover 23 has a circular mesh structure, and the screen cover 23 is fixedly connected to the top edge of the sampling cylinder 17. The screen cover 23 can prevent large impurities in the wastewater from entering the sampling cylinder 17, ensuring the purity of the extracted wastewater. The top of the sampling cylinder 17 is equipped with a screen cover 23.

[0026] The implementation principle of a wastewater extraction device for detection according to an embodiment of this application is as follows: When the wastewater extraction device is working, the operator sends commands to the first drive motor 4 and the second drive motor 10 through the control panel 19 located in the middle of the lower left end of the vertical plate 2. The first drive motor 4 is started, and its output end drives the long screw 18 to rotate. Since the long screw 18 is threadedly connected to the cantilever arm 8, and the front end of the cantilever arm 8 slides in the front groove 5 of the vertical plate 2 and the limiting slider 7 at the rear right end slides in the right groove 5 of the vertical plate 2, the cantilever arm 8 can move up and down smoothly to adjust the height position. Then, the second drive motor 10 is started, and its output end drives the rope winding roller 11 to rotate, thereby releasing or winding the rope body 12 wrapped on its outer surface, thereby adjusting the height of the connecting seat 20 and the connected parts connected to the threaded joint 13 at one end of the rope body 12. The six-bar frame 21 connected to the lower end of the connecting seat 20 is distributed in a regular hexagonal three-dimensional shape, and its outer side is fixedly connected to the outer... The ring frame 14 enhances the overall structural strength. The conical weight 16, connected to the lower end of the six-bar frame 21 by six connecting rods 15, reduces resistance when sinking into wastewater due to its downward-pointing conical shape, making it easier for the entire sampling component to sink. Meanwhile, the long rods 24 inserted into the holes 22 around the upper end of the six-bar frame 21 can be adjusted and fixed in height with the cooperation of nuts 25 and limiting rings 6. The sampling cylinder 17, fixed to the outside of the bottom connecting block 3 of the long rods 24, is also attached accordingly. When the sampling cylinder 17 reaches a suitable depth, the water in the wastewater enters the sampling cylinder 17 through the circular mesh cover 23 set at the top. The mesh cover 23 can prevent large impurities from entering and ensure the purity of the extracted wastewater. After sampling is completed, the second drive motor 10 is operated in reverse to make the rope roller 11 wind around the rope body 12, pulling up the sampling cylinder 17. Then, the height of the cantilever arm 8 is adjusted by the first drive motor 4 to move the sampling cylinder 17 to a suitable position so that the wastewater sample for testing can be taken out.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
