DETAILED DESCRIPTION

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model provides a device for automatically monitoring water quality and quantity at a sewage outlet into a river, such as Figure 1-6 As shown, the automatic monitoring device for water quality and quantity of a sewage outlet into a river comprises: a vertical pole 1 arranged at one side of the sewage outlet into a river, a support arm 2 is fixedly installed on the top of the vertical pole 1, and one end of the support arm 2 extends to the top of the sewage outlet into the river; two assembly frames 3, two of the assembly frames 3 are symmetrically fixedly installed on the support arm 2, and both of the assembly frames 3 are provided with a slide bar 4 that can slide up and down; a floating plate 5, the floating plate 5 is fixedly installed on the bottom end of the slide bar 4, a fixed frame 6 is fixedly installed on the floating plate 5, and a monitoring probe 7 for monitoring water quality and quantity is provided on the fixed frame 6; a protective mesh plate 8 for filtering impurities and protecting the monitoring probe 7, the protective mesh plate 8 is fixedly installed on the bottom of the floating plate 5; a cleaning mechanism for cleaning the protective mesh plate 8, and the cleaning mechanism is arranged on the fixed frame 6.

[0024] It should be noted that the existing automatic water quality and water quantity monitoring devices are usually able to automatically monitor water quality parameters (such as pH value, dissolved oxygen, turbidity, etc.) and water quantity continuously, and transmit the data to the central control system for analysis and recording; The probe position is fixed: In most automatic monitoring devices, the position of the water quantity monitoring probe (such as flow meter, water level meter, etc.) is fixed. This means that no matter how the water level changes, the measurement point of the probe is always in the same position; The water quantity reflection is inaccurate: Since the probe position remains unchanged, when the water level rises or falls, the probe may not be able to accurately measure the water quantity changes of the entire water body. Especially in the case of large changes in water level, this fixed position measurement method will cause data distortion; Data accuracy decreases: Since it cannot accurately reflect the actual water quantity changes, the data recorded by the monitoring device may have large errors. This error may affect subsequent data analysis and decision making; Data validity is limited: Inaccurate data not only cannot provide effective reference information, but may also mislead decision makers to make wrong judgments, especially in emergency situations that require rapid response. This misleading may have serious consequences. Therefore, it is necessary to provide an automatic water quality and water quantity monitoring device for river discharge outlets to solve the above problems;

[0025] In this embodiment, the vertical rod 1 is firmly set on one side of the sewage outlet into the river, and a support arm 2 is installed on the top of the vertical rod 1. One end of the support arm 2 extends to the top of the sewage outlet into the river, providing a stable support structure for the subsequent monitoring components; two assembly frames 3 are symmetrically fixed on the support arm 2, and each assembly frame 3 is provided with a sliding rod 4 that can slide up and down. This design enables the sliding rod 4 to slide up and down according to the water level changes under the guidance of the assembly frame 3; a floating plate 5 is fixedly installed on the bottom end of the sliding rod 4, and the floating plate 5 will rise and fall with the change of the water level; a fixed frame 6 is installed on the floating plate 5, and a monitoring probe 7 for monitoring water quality and quantity is provided on the fixed frame 6. Since the floating plate 5 can rise and fall with the water level, the monitoring probe 7 can also adjust its position accordingly to ensure that it is always located at the appropriate position of the water body, thereby accurately reflecting the changes in the actual water volume; the protective mesh plate 8 is fixedly installed at the bottom of the floating plate 5 to filter out impurities in the water body and protect the monitoring probe 7 from interference and damage by impurities; the cleaning mechanism is set on the fixed frame 6 to clean the impurities accumulated on the protective mesh plate 8 regularly or as needed, ensure the filtering effect of the protective mesh plate 8, and ensure the normal operation of the monitoring probe 7; when the water level of the sewage outlet into the river changes, the floating plate 5 will rise and fall with the water level, driving the slide bar 4 to slide on the assembly frame 3. This design enables the monitoring probe 7 to always remain in the appropriate position of the water body, and can accurately reflect the changes in the actual water volume regardless of how the water level changes; the filtering effect of the protective mesh plate 8 can protect the monitoring probe 7 from interference and damage by impurities, and improve the accuracy and effectiveness of the monitoring data; the setting of the cleaning mechanism can clean the impurities on the protective mesh plate 8 regularly or as needed, ensure the filtering effect of the protective mesh plate 8, and extend the service life of the monitoring probe 7.

[0026] In a further preferred embodiment of the utility model, the cleaning mechanism includes: a mounting frame 9 fixedly mounted on the fixing frame 6; an electric telescopic rod 10 fixedly mounted on the mounting frame 9 for regulating the lifting; a connecting sleeve 11 arranged on the top end of the output rod of the electric telescopic rod 10; and a cleaning brush 12 fixedly mounted on the bottom end of the connecting sleeve 11 for cleaning the protective mesh plate 8.

[0027] In this embodiment, the design of the cleaning mechanism further improves the cleaning effect of the protective mesh 8, ensuring that the monitoring probe 7 can continuously and accurately obtain water quality and quantity data. The following is a detailed explanation of the cleaning mechanism and its beneficial effects in combination with the above content: the mounting frame 9 is fixedly mounted on the fixing frame 6, providing a stable mounting platform for the cleaning mechanism; the electric telescopic rod 10 is fixedly mounted on the mounting frame 9, and is used to control the lifting and lowering of the cleaning brush 12. The electric telescopic rod 10 can automatically or manually control the lifting height as needed, which is convenient for comprehensive cleaning of the protective mesh 8; the connecting sleeve 11 is set on the top of the output rod of the electric telescopic rod 10, as a connecting piece between the electric telescopic rod 10 and the cleaning brush 12. The connecting sleeve 11 ensures a stable connection between the cleaning brush 12 and the electric telescopic rod 10, while allowing the cleaning brush 12 to adjust a certain angle to adapt to different cleaning needs; the cleaning brush 12 is fixedly mounted on the bottom end of the connecting sleeve 11, and directly contacts the protective mesh 8 for cleaning. The cleaning brush 12 is made of soft and durable material, which can effectively remove impurities on the protective mesh 8 without damaging the protective mesh 8; when a large amount of impurities accumulate on the protective mesh 8, the electric telescopic rod 10 starts to work, pushing the connecting sleeve 11 and the cleaning brush 12 downward to the top of the protective mesh 8. The cleaning brush 12 contacts the protective mesh 8 and starts cleaning, brushing the impurities off the protective mesh 8; the lifting function of the electric telescopic rod 10 enables the cleaning brush 12 to cover the entire area of ​​the protective mesh 8, ensuring comprehensive cleaning of the protective mesh 8. This design ensures the stability and reliability of the cleaning mechanism during long-term use.

[0028] In a further preferred embodiment of the utility model, a screw 13 for limiting position is provided on the connecting sleeve 11 , and one end of the screw 13 is threadedly penetrated through the output rod of the electric telescopic rod 10 .

[0029] In this embodiment, by providing a screw 13 for limiting the position on the connecting sleeve 11, a stable connection between the connecting sleeve 11 and the output rod of the electric telescopic rod 10 is achieved.

[0030] In a further preferred embodiment of the utility model, a sleeve block 14 for assembling the slide bar 4 is fixedly mounted on the assembly frame 3 , a ball 15 is embedded on the inner wall of the sleeve block 14 , and a limit block 16 is fixedly mounted on the top end of the slide bar 4 .

[0031] In this embodiment, the assembly method of the assembly frame 3 and the slide bar 4 is optimized, specifically by introducing a sleeve block 14 and a ball bearing 15, and setting a limit block 16 at the top of the slide bar 4, so as to improve the smoothness and stability of the slide bar 4 sliding in the assembly frame 3. The following is a detailed explanation of this improvement and its beneficial effects in combination with the above content: a sleeve block 14 is fixedly installed on the assembly frame 3 for assembling the slide bar 4. The design of the sleeve block 14 provides a precise sliding track for the slide bar 4, ensuring the stable movement of the slide bar 4 in the vertical direction; the inner wall of the sleeve block 14 is inlaid with a ball bearing 15. The introduction of the ball bearing 15 transforms the sliding friction of the slide bar 4 in the sleeve block 14 into rolling friction, greatly reducing the friction force and improving the smoothness of sliding; the limit block 16 is fixedly installed at the top of the slide bar 4. The design of the limit block 16 can prevent the slide bar 4 from escaping from the sleeve block 14 during the sliding process, and can also provide a buffer when the slide bar 4 slides to the extreme position to avoid damage to the equipment.

[0032] In a further preferred embodiment of the utility model, the cleaning brushes 12 provided on the floating plate 5 are all arc-shaped, and the bristles on the cleaning brushes 12 can contact the surface of the floating plate 5 .

[0033] In this embodiment, the designs of the floating plate 5 and the cleaning brush 12 are optimized, in particular, the cleaning brush 12 is designed to be arc-shaped, and its bristles can contact the surface of the floating plate 5. This design brings significant improvements and beneficial effects, and the following is a detailed explanation of this: Arc-shaped cleaning brush 12: The shape of the cleaning brush 12 is designed to be arc-shaped. This design takes into account the shape of the floating plate 5 and the cleaning requirements, so that the cleaning brush 12 can fit the surface of the floating plate 5 more closely, especially at the edges and corners of the floating plate 5. Bristles contact with the floating plate 5: The bristles on the cleaning brush 12 are designed to be soft and dense enough to ensure that they can fully contact the surface of the floating plate 5. This contact ensures that the cleaning brush 12 can effectively remove impurities and dirt on the surface of the floating plate 5.

[0034] In a further preferred embodiment of the utility model, the floating plate 5 is provided with an arc-shaped through groove adapted to the cleaning brush 12 , and the floating plate 5 is also provided with a through hole for the monitoring probe 7 to pass through.

[0035] In this embodiment, the design of the floating plate 5 is further optimized, in particular, an arc-shaped through groove adapted to the cleaning brush 12 and a through hole for the monitoring probe 7 to pass through are provided on the floating plate 5. This design brings significant beneficial effects, and the following is a detailed explanation of this: an arc-shaped through groove adapted to the cleaning brush 12 is provided on the floating plate 5. This design enables the cleaning brush 12 to move along the path of the arc-shaped through groove, thereby more accurately cleaning the surface of the floating plate 5. The shape and size of the arc-shaped through groove match the cleaning brush 12, ensuring that the cleaning brush 12 can completely cover the area of ​​the floating plate 5 that needs to be cleaned; the floating plate 5 is also provided with a through hole for the monitoring probe 7 to pass through. This design enables the monitoring probe 7 to directly pass through the floating plate 5 and contact the water body, thereby obtaining more accurate water quality and quantity data. The position and size of the through hole are accurately calculated to ensure that the monitoring probe 7 can be stably installed on the floating plate 5 and will not be disturbed by the floating plate 5.

[0036] In a further preferred embodiment of the present invention, a base plate is fixedly mounted on the bottom of the vertical rod 1, and assembly holes are symmetrically opened on the base plate.

[0037] In this embodiment, the bottom design of the vertical rod 1 is optimized, specifically, a base plate is fixedly installed at the bottom of the vertical rod 1, and assembly holes are symmetrically opened on the base plate. This design brings the following beneficial effects: the base plate is fixedly installed at the bottom of the vertical rod 1. This design increases the stability of the entire device, so that the entire device can be placed more firmly on the ground, avoiding shaking or tilting due to external forces; the assembly holes are symmetrically opened on the base plate. The existence of the assembly holes makes it possible to fix the device, and the user can fix the device to the ground or other fixed structures by passing bolts or other fasteners through the assembly holes.
