Long-term exposure to these harsh environments may cause the equipment to perform poorly or break down.

[0003] The harsh environment cannot be changed, but the equipment can be protected by adding protective devices. The protective devices of existing water quality detection devices generally use grid protection to resist the impact of external sand, stones and other objects, effectively isolating and protecting the water quality detection device and extending its service life.

[0004] Chinese patent (CN 218594513 U, 2023.03.10) discloses a water quality detection buoy capable of cleaning attached impurities; its technical solution installs the detector assembly inside the protective net cylinder for protection, and cleans the impurities on the outer wall of the protective net cylinder with a brush roller. However, the single-layer protective net cylinder method has poor isolation effect, especially for relatively small stones or sand particles. Moreover, the mechanism for cleaning the surface impurities of the protective net cylinder is complex and has high manufacturing cost.

[0005] Due to the above reasons, the present inventor has conducted in-depth research on existing water quality detection devices and their protective devices in order to design a city pipe network water quality detection device that can effectively isolate sand and stones and other impurities, protect the water quality detection device, has a simple structure, good sand cleaning effect, is easy to install and arrange, and has low cost.

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent.

[0053] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0054] According to the urban pipe network water quality testing device with double-layer protective mesh provided in this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in the figure, the detection device includes a water quality detection device body 1, a mounting plate 2, a double-layer protective net cylinder 3, and a rotary drive mechanism 4;

[0055] The water quality of the urban pipe network is detected by the main body 1 of the water quality testing device.

[0056] A mounting through hole 21 is provided on the surface of the mounting plate 2; the main body 1 of the water quality testing device is vertically mounted on the mounting plate 2, and one end of the main body 1 of the water quality testing device passes through the mounting through hole 21.

[0057] The double-layer protective net cylinder 3 is open at one end and closed at the other end, and its closed end is set as a cone; the open end of the double-layer protective net cylinder 3 is rotatably mounted on the plate surface of the mounting plate 2; the main body 1 of the water quality detection device passes through the mounting through hole 21 and extends into the double-layer protective net cylinder 3 from the open end;

[0058] The rotary drive mechanism 4 is mounted on the mounting plate 2 and is connected to the double-layer protective net cylinder 3. The rotary drive mechanism 4 drives the double-layer protective net cylinder 3 to rotate, thereby centrifugally removing impurities attached to the double-layer protective net cylinder 3.

[0059] The water quality testing device in this application employs a double-layer protective mesh cylinder to protect the main body of the device. This secondary filtration of impurities such as silt and stones in the urban pipe network water enhances the protective effect. During use, the mounting plate is fixedly installed in the pipes or manholes of the urban pipe network, with the conical closed end of the protective mesh cylinder facing the direction of water flow. This reduces the impact of silt and gravel on the equipment, thereby improving the service life and testing stability of the water quality testing device.

[0060] Furthermore, this application employs a centrifugal rotation method to clean the mud and other debris adhering to the double-layer protective net cylinder. Since the double-layer protective net cylinder rotates in water, the centrifugal force causes the mud and other debris to detach from the double-layer protective net cylinder. The rotating and agitated water flow also cleans the walls of the double-layer protective net cylinder, thus achieving effective cleaning. Regular cleaning prevents the protective net cylinder from becoming clogged with mud and sand, thereby improving the detection accuracy of the main body of the water quality testing device. Overall, this water quality testing device has a simple structure, good protective effect, and powerful cleaning function, achieving effective cleaning of the double-layer protective net cylinder.

[0061] In a preferred embodiment, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the double-layer protective net cylinder 3 includes an inner protective net cylinder 32 and an outer protective net cylinder 31 sleeved on its outer side;

A connecting mechanism, such as multiple connecting steel bars, can also be provided at the open ends of the outer protective mesh cylinder 31 and the inner protective mesh cylinder 32 to connect and fix each other. The connecting mechanism ensures that the relative position between the outer protective mesh cylinder 31 and the inner protective mesh cylinder 32 is stable and that they can rotate synchronously.

Moreover, the structure is simple and efficient. It is only necessary to start the drive motor 41 periodically to ensure that both the outer protective net cylinder 31 and the inner protective net cylinder 32 are in a clean state.
