[0002] This invention relates to the technical field of wastewater sampling equipment, which is an instrument specifically designed to obtain representative water samples from wastewater pipes, discharge outlets, rivers, or wastewater treatment facilities. Its main functions include automated wastewater sample collection, allowing for sample collection at set time intervals, flow rates, or manually, greatly improving the scientific rigor and efficiency of sampling. Some devices also feature refrigeration and preservation functions to prevent compositional changes during collection and storage. Furthermore, modern wastewater sampling equipment supports remote monitoring, automatic data recording and transmission, facilitating data management and quality traceability for operators. The equipment can also precisely control the sampling volume and perform multi-point sampling as needed to meet the requirements of different environments and monitoring targets.

[0003] Wastewater sampling equipment plays a vital role in environmental protection and management. Firstly, it provides environmental regulatory departments with accurate and reliable wastewater discharge data, serving as the basis for determining whether enterprises or facilities meet discharge standards. Secondly, continuous and regular sampling allows for the tracking of pollution source trends, effectively supporting environmental emergency monitoring and accident response, and providing a scientific basis for the investigation and handling of pollution incidents. Furthermore, data accumulated over a long period can be used for scientific research, helping to analyze water quality changes and the effectiveness of pollution control measures. In short, wastewater sampling equipment is a crucial foundational tool for ensuring environmental safety, protecting public health, and promoting the scientific and standardized development of pollution prevention and control efforts.

The chain-type can delivery structure realizes the cyclic delivery and precise positioning of multiple sampling cans 2 through the drive sprocket 11, the driven sprocket 12 and the transmission chain 13. The operating principle is similar to the tool magazine of a machining center, which can efficiently store and switch a large number of sampling cans 2, realize the automatic collection and orderly preservation of samples at different times and locations under unattended conditions, and greatly improve the automation and continuous operation capability of the equipment.

[0020] In this embodiment, the clamping part includes a clamping seat 14, which is fixedly installed on the transmission chain 13. A rubber pad 15 is provided at the lower end of the clamping seat 14, and a clamping sleeve 27 is provided on the clamping seat 14. The clamping sleeve 27 is a C-shaped sleeve.

[0021] In this embodiment, the water inlet end of the filling pipe 5 is fixedly installed with an anchoring hook 16 and a float 17. The installation of the anchoring hook 16 and the float 17 at the water inlet end enables the sampling port to be suspended or anchored in the target water layer, avoiding deviation of the sampling position due to the movement of the equipment itself or the influence of water flow, thereby ensuring the accuracy and representativeness of the sampled water.

[0022] In this embodiment, a water storage tank 18 is fixedly installed on the main vehicle body 1, and a water pump 19 is fixedly installed inside the water storage tank 18. The output end of the water pump 19 is connected to the filling pipe 5, and a three-way control valve 20 is connected to the output end of the water pump 19 and the filling pipe 5. The main vehicle body 1 has a built-in water storage tank 18 and a water pump 19, which can provide a backup water source for cleaning the equipment itself and rinsing the sampling pipeline or sampling tank 2.

[0024] In this embodiment, the walking structure is further configured to include two pairs of electric wheels 24, which are mounted on the lower wall of the main vehicle body 1. The electric wheels 24 are tracked wheels, and each pair of electric wheels 24 is connected to a walking track 26. Equipped with a tracked walking device, compared with ordinary wheeled mechanisms, it can better adapt to complex environments such as soft soil and wetlands, and the water-land interface, expanding the application scenarios of sewage sampling equipment and improving the flexibility and passability of use.

[0025] Its detailed connection methods are well-known technologies in this field; such as Figure 1 As shown, transport the equipment to the target monitoring area and place it in a suitable location. Ensure the main vehicle 1 has sufficient power and check the status of the solar panels 22 and battery 23. As needed, load several pre-sterilized sampling tanks 2 into the chain-type tank conveying structure, ensuring each sampling tank 2 is well-sealed and correctly installed in the clamping position. Set parameters such as sampling time, location, and water depth via the control panel or remote terminal; various modes such as timed sampling, interval sampling, or point sampling can be selected. If necessary, the sampling volume and specific sample indicators to be collected for each sampling tank 2 can be set.

[0026] The equipment is started, and the traveling structure drives the main vehicle 1 to the designated sampling point automatically, with an additional positioning system determining its precise location. Upon arrival at the sampling point, the equipment automatically stops and stabilizes to prepare for subsequent sampling. Driven by the electric push rod 4, the filling tube 5 is inserted into the sampling tank 2. The submersible pump 6 starts, drawing water samples through the inlet and filling tube 5, and accurately injecting the water samples into the currently positioned sampling tank 2 through the needle-type injection port. The exhaust pipe 7 simultaneously discharges air from the tank, ensuring a smooth sampling process without vacuum obstruction. After sampling, the electric push rod 4 returns to its original position, and the sampling tank 2 automatically moves to the storage location. The chain-type tank delivery structure delivers the next empty tank to the sampling position. The first motor 8 and gear reducer 10 drive the drive sprocket 11 to rotate, causing the transmission chain 13 to rotate, moving the sampling tank 2 in preparation for the next sampling.

[0027] For sampling of specific water layers such as the surface, middle, and bottom, anchoring hooks 16 and floats 17 can be installed to assist in positioning the filling pipe 5 and ensure the sampling port is at the correct water depth. The submersion depth of the filling pipe 5 and the order of sampling points can be adjusted according to sampling needs. The sampling tank 2 moves automatically without manual intervention. During sampling intervals or after sampling, the sampling pipeline and the inside and outside of the sampling tank 2 can be cleaned through the equipment's built-in water tank 18 and water pump 19 via a three-way control valve 20 to prevent cross-contamination. Each cleaning operation can be automatically executed through the control system.

[0028] Additional hardware and software can be installed as needed by the operators. During operation, the equipment is continuously powered by solar panels 22, with batteries 23 responsible for energy storage and supply, ensuring long-term, continuous, and reliable operation. It can achieve unattended operation, periodic or emergency sampling in remote field environments. After sampling, all collected samples are sealed and stored in sampling containers 2, awaiting subsequent manual retrieval and transport to the laboratory for analysis. Simultaneously, the equipment can automatically record relevant data such as sampling time, location, and sample volume, achieving full-process information management.
