Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection and sampling technology, and in particular to a wastewater detection and sampling device. Background Technology
[0002] Wastewater refers to the water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other non-useful water such as initial rainwater runoff into drainage pipes and ditches. Generally, it refers to water that cannot be recycled after certain technical treatment or water that cannot be purified to meet certain standards after primary pollution. In daily life, outdoor waterways often receive various kinds of wastewater. In order to treat the wastewater in these waterways, wastewater sampling devices are needed.
[0003] Current wastewater sampling devices have limitations, particularly when sampling from distant areas of rivers. Their design makes precise positioning and stable sampling difficult, and operators often cannot effectively control the sampling location, leading to insufficient sample representativeness. Furthermore, the limited range of these devices often necessitates the use of boats or other auxiliary tools for distant locations such as the middle of the river or the opposite bank, increasing operational difficulty and labor costs, and making them more susceptible to external interference. This reduces sampling accuracy and reliability, affecting the objectivity and effectiveness of subsequent water quality analysis.
[0004] To address the aforementioned problems, this utility model proposes a wastewater detection and sampling device. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater detection and sampling device, comprising a base, an airbag fixedly installed at the bottom end of the base, and a control component fixedly installed on the upper end face of the base; electric pushers are provided at both ends of the base; multiple fixing plates are evenly fixedly installed on both sides of the base, and sampling cylinders are lifted and installed on each fixing plate, with a sampling port opened at the top of the side wall of the sampling cylinder; and a liquid discharge port is fixedly installed on the upper end face of the sampling cylinder.
[0007] The present invention is further configured such that a sealing plate is rotatably installed inside each sampling port, and a torsion spring is provided at the rotatable connection between the sealing plate and the sampling port.
[0008] The present invention is further configured such that a guide groove is provided on the side wall of the fixed plate, a movable block is slidably installed inside the guide groove, a threaded groove is provided on the movable block, and a screw is fixedly installed on the side wall of the sampling cylinder, with the threaded groove and the screw threadedly engaged.
[0009] The present invention is further configured such that an electric push rod is fixedly installed on the top of each of the fixed plates, and the output end of the electric push rod extends into the interior of the guide groove and is fixedly connected to the moving block.
[0010] The present invention is further configured such that a plug is fitted at the top of the discharge port.
[0011] The present invention is further configured such that the base, airbag, control component, electric thruster and guide groove are all waterproof.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This wastewater sampling and testing device comprises a main structure including an airbag, control components, an electric propeller, a sampling cylinder, a sampling port, a torsion spring-loaded sealing plate, and an electric push rod. The electric propeller moves the device to the target point, and the electric push rod lowers the sampling cylinder, submerging the sampling port in the water. Water pressure pushes open the sealing plate, allowing water to enter.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0017] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0018] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a wastewater detection and sampling device, including a base 1, an airbag 2 fixedly installed at the bottom of the base 1, and a control component 3 fixedly installed at the upper surface of the base 1; electric propellers 4 are provided at both ends of the base 1; the base 1, airbag 2, control component 3, and electric propellers 4 are all waterproof. The base 1 serves as the basic carrier, the airbag 2 provides buoyancy so that the device can float on the water surface, the control component 3 is responsible for overall control, and the electric propellers 4 provide power so that the device can move in the water. All of the above structures are waterproofed using general waterproofing methods, such as waterproof gaskets at the joints and waterproof coating on the outer wall; this ensures that each core component can work normally in both surface and underwater environments, improving the reliability and service life of the device.
[0020] Multiple fixing plates 5 are evenly fixedly installed on both sides of the base 1, and sampling cylinders 6 are lifted and installed on each fixing plate 5. The multiple fixing plates 5 provide multiple mounting points, allowing multiple sampling cylinders 6 to be installed simultaneously, providing a structural basis for parallel sampling at different locations.
[0021] A sampling port 7 is provided at the top of the side wall of the sampling cylinder 6. A sealing plate 9 is rotatably installed inside the sampling port 7, and a torsion spring is provided at the rotatable connection between the sealing plate 9 and the sampling port 7. The sampling port 7 is the inlet of the water sample. The rotatably installed sealing plate 9, in conjunction with the torsion spring, can automatically close when there is no external force to prevent contaminants from entering or samples from leaking during non-sampling periods. During sampling, the pressure of the water can be used to push open the sealing plate 9 to allow water to enter. The structure is simple and ingenious, and achieves automatic opening and closing.
[0022] A guide groove 10 is provided on the side wall of the fixed plate 5. A movable block 11 is slidably installed inside the guide groove 10. A threaded groove 12 is provided on the movable block 11. A screw 13 is fixedly installed on the side wall of the sampling cylinder 6. The threaded groove 12 and the screw 13 are threadedly engaged. An electric push rod 14 is fixedly installed on the top of the fixed plate 5. The output end of the electric push rod 14 extends into the interior of the guide groove 10 and is fixedly connected to the movable block 11. The guide groove 10 provides a vertical moving track for the movable block 11. The electric push rod 14 serves as a power source. By pushing the movable block 11, and then through the threaded groove 12 and the threaded engagement with the screw 13, the linear motion of the movable block 11 is converted into a stable and reliable lifting motion of the sampling cylinder 6, thereby controlling the water immersion depth of the sampling port 7.
[0023] A drain port 8 is fixedly installed on the upper end face of the sampling cylinder 6, and a plug 15 is fitted at the top of the drain port 8. The drain port 8 is used to remove the water sample sealed in the sampling cylinder 6 after sampling. The fitted plug 15 can achieve a good seal, prevent the sample from leaking or being contaminated during transportation, and ensure the integrity of the sample.
[0024] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.
[0025] Working principle: Powered by the electric propulsion unit 4, the wastewater detection and sampling device can smoothly navigate and move to the designated target location at a specific depth in the river. Upon reaching the predetermined sampling point, the control unit 3 activates the electric push rod 14. The output end of the electric push rod 14 pushes the moving block 11 to slide downwards along the guide groove 10 on the fixed plate 5; the moving block 11 drives the sampling cylinder 6 to descend. As the sampling cylinder 6 descends, the sampling port 7 on its side wall gradually submerges below the water surface; the external water pressure overcomes the torsion spring torque at the pivot of the sealing plate 9, pushing the sealing plate 9 to flip inwards and open, allowing water to flow into the sampling cylinder 6 through the sampling port 7. The sampling volume can be monitored in real time by sensors (such as liquid level sensors) preset at different heights inside the sampling cylinder 6. Once the preset capacity is reached, the control component 3 immediately issues a command, and the electric push rod 14 reverses its operation, pulling the moving block 11 and the sampling cylinder 6 connected to it to rise synchronously, causing the sampling port 7 to leave the water surface. Once out of the water, the water pressure disappears, and the sealing plate 9 automatically springs back to its original position under the action of the torsion spring, tightly sealing the sampling port 7, thereby ensuring that the water sample inside the sampling cylinder 6 is completely isolated from the external environment, and the single sampling operation is completed. Afterwards, the device can be moved to a new horizontal or vertical position again with the help of the electric propeller 4, and the other independent sampling cylinders 6 can be controlled to perform the same lifting and lowering sampling process, ultimately achieving serialized and precise sampling of wastewater at different locations.
[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
