[0002] With the development of society, water pollution is also gradually increasing. In order to effectively control it, river water quality analysis is an important step in prevention. Most of the existing water quality detection and analysis work uses water quality collection devices to collect water samples from the river waters that need to be tested, and then bring the water samples back to the testing room, and use water quality testing instruments to test and analyze the collected water quality. This method has a cumbersome detection process and a long detection time, resulting in low detection efficiency.

[0003] At present, there are water quality detection devices for real-time detection of water quality in rivers. They generally include a float, photovoltaic panels, batteries, water quality monitoring devices and protective covers. The protective cover is provided with filter holes. The device can detect water quality in real time in the river, thereby improving detection efficiency.

[0004] However, in rivers with more pollutants, some aquatic plants or garbage can easily clog the filter holes and even pass through the filter holes into the lower protective cover. Moreover, after aquatic plants and other garbage clog the filter holes, they can easily adhere to and entangle the filter holes, making them difficult to detach, thus affecting normal detection. Summary of the invention

[0005] On the one hand, in order to prevent the filter holes from being blocked, the present application provides a device for analyzing apparent abnormalities in river water quality.

[0008] By adopting the above technical solution, when cleaning is needed, the driving component drives the cleaning rod to be inserted into the cleaning hole and then detached from the cleaning hole, and the power component drives the frame to move in a circle along the protective cover, so that the cleaning rod on the frame continuously cleans the filter holes on the protective cover, preventing aquatic plants and other garbage from clogging the filter holes, thereby ensuring normal detection of the water quality monitoring and analysis device.

In the process of the driving source driving the mounting ring to move upward, the cleaning rod and the driving block move upward, and under the action of the reset member, the cleaning rod moves toward the inside of the protective cover to make the cleaning rod disengage from the filter hole; in the process of the driving source continuously driving the mounting ring to move up and down, the cleaning rod is continuously inserted into and disengaged from the filter hole, thereby achieving the purpose of automatically cleaning the filter hole.

[0013] Optionally, the cleaning rod includes a mounting section and an insertion section, the mounting section is arranged on the vertical rod, a spherical hole is opened on the side wall of the mounting section close to the protective cover, a hinge ball is fixedly arranged at one end of the insertion section, the hinge ball is hinged in the spherical hole, the insertion section is used to be inserted into the filter hole, a pointed end is arranged at one end of the insertion section away from the mounting section, and an elastic member is arranged on the mounting section for driving the insertion section to remain horizontal.

[0017] Optionally, a screw rod is fixedly provided on the side wall of the installation section along the length direction of the installation section, and the collar is threadedly sleeved on the screw rod.

[0018] By adopting the above technical solution, the ring is rotated and moved on the screw rod, so as to achieve the purpose of adjusting the distance from the ring to the disc. The prestress of the elastic rope can be adjusted to prevent the insertion section from deflecting due to changes in the elastic force of the elastic rope caused by fatigue changes, and the deflection angle of the insertion section is adjusted to ensure that the insertion section remains in a horizontal state.

[0019] Optionally, a plurality of anchoring assemblies are arranged on the float along the circumference of the float, and the anchoring assemblies include a counterweight, a pull rope and a winding wheel.

The side wall of the driving block 62 abutting against the cleaning rod 5 is provided with an inclined surface 621, and the distance from the inclined surface 621 to the driving rod 61 gradually decreases from the top end to the bottom end of the driving block 62.

[0054] Reference Figure 6 and Figure 7 The reset member 63 is arranged on the vertical rod 32 to drive the cleaning rod 5 to move in the direction away from the protective cover 2. The reset member 63 is a reset spring sleeved on the cleaning rod 5. The cleaning rod 5 is fixedly provided with an abutment plate 513. One end of the reset spring abuts against the side wall of the vertical rod 32, and the other end abuts against the abutment plate 513.

The diameter of the insertion section 52 is equal to or slightly smaller than the diameter of the filter hole 22. A tip portion 521 is provided at one end of the insertion section 52 away from the mounting section 51. The tip portion 521 is set as a conical structure.

[0057] During the process of inserting the cleaning rod 5 into the filter hole 22, the tip portion 521 guides the cleaning rod 5. If there is a small misalignment between the cleaning rod 5 and the filter hole 22, under the guidance of the tip portion 521, the insertion section 52 is deflected accordingly, so that the insertion section 52 can be smoothly inserted into the filter hole 22 to complete the cleaning function, thereby effectively improving applicability.

By rotating the collar 5121, the collar 5121 moves on the screw rod 512, and the distance between the collar 5121 and the disc 522 is adjusted. The prestress of the elastic rope 511 can be adjusted to prevent the elastic force of the elastic rope 511 from changing due to fatigue, which causes the insertion section 52 to deflect. The deflection angle of the insertion section 52 is adjusted to ensure that the insertion section 52 remains in a horizontal state.

[0060] The implementation principle of the embodiment of the present application is as follows: when cleaning is required, the driving source drives the mounting ring 31 to move downward, the mounting ring 31 drives the driving rod 61 to move downward, and then drives the driving block 62 to move, the inclined surface 621 of the driving block 62 abuts against the cleaning rod 5, and pushes the cleaning rod 5 to insert into the filter hole 22, so as to achieve the purpose of cleaning the filter hole 22, and in the process of the driving source driving the mounting ring 31 to move upward, the cleaning rod 5 and the driving block 62 move upward, and under the action of the reset member 63, the cleaning rod 5 moves toward the inside of the protective cover 2, so that the cleaning rod 5 is separated from the filter hole 22. The power assembly 4 drives the frame 3 to make a circular motion along the protective cover 2, so that the cleaning rod 5 on the frame 3 continuously cleans the filter hole 22 on the protective cover 2, prevents the water grass and other garbage from clogging the filter hole 22, and ensures the normal detection of the water quality monitoring and analysis device.
