[0031] The utility model provides a protective element, which can be applicable to various hydrological and water quality monitoring equipment or other underwater devices that need to detect liquids, but is not limited here.

[0032] Reference Figures 1 to 5In one embodiment of the utility model, the protective member includes a protective body 10 having a first end and a second end. The protective body 10 is provided with one or more filter holes 10a and a detection cavity 10b connected to the filter holes 10a. The filter holes 10a are used to block impurities having a particle size larger than the average particle size of impurities in the liquid, and the filter holes 10a are all located above the test area of ​​the probe 20. The detection cavity 10b is suitable for covering the probe 20 of the detection sensor. The detection cavity 10b is arranged to penetrate from the first end of the protective body 10 to the second end thereof and form an installation port 10c at the first end and a drainage port 10d at the second end. The installation port 10c is suitable for being installed on the detection sensor.

[0033] The hydrological and water quality detection sensor detects the water flowing through the detection cavity 10 b . The detected water enters the detection cavity 10 b through the filter hole 10 a , and then flows out through the drain port 10 d at the bottom of the protective body 10 .

[0034] In this embodiment, the protective body 10 may be tubular or cylindrical, and is preferably a circular tube-shaped thin-walled cover with a certain height, which is not limited here.

[0035] The shape of the filter hole 10a can be circular, oval, long strip or square, etc., which is not limited here. In order to prevent the water flow from directly scouring the probe 20 and affecting its detection, and to make the water flow pass through the probe 20 of the hydrological and water quality detection sensor at a high speed to improve the detection accuracy and stability, such as Figure 4 and Figure 5 As shown, in this embodiment, the number of the filter holes 10a is one or more, and the distance between the filter holes 10a as a whole and the first end of the protective body 10 may be smaller than the distance between the probe 20 and the first end of the protective body 10. In this embodiment, the protective body 10 is preferably in the shape of a circular tube, and a plurality of filter holes 10a are located on the side wall of the protective body 10 close to the top surface, and may be evenly arranged along the circumferential center axis of the protective body 10. In other words, the filter holes 10a should be arranged as high as possible, and may be specifically arranged below the mounting port 10c and above the top surface of the detection cavity 10b / the entire probe 20. In this way, the filter holes 10a can all be located at a suitable position above the test area of ​​the probe 20, so that the liquid entering from the filter holes 10a can flow into the test area of ​​the probe 20, thereby improving the accuracy of the probe 20 test.

[0036] It can be understood that the utility model improves the protective structure of the detection sensor and only sets filter holes 10a of appropriate size on the circumferential surface of the protective body 10, thereby greatly reducing the number of filter holes 10a, blocking debris with larger particle sizes, and opening a drain port 10d at the bottom of the protective body to allow the liquid and debris entering from the filter hole 10a to be quickly discharged. This helps to provide a more stable detection environment for the detection sensor, effectively prevent the filter holes 10a from being blocked, and reduce the impact of each water flow flushing, thereby improving the stability of the detection data of the hydrological and water quality detection sensor, and can maintain the long-term cleanliness of the detection cavity 10b, reducing the cleaning frequency of the protective component.

[0037] Main reference Figures 1 to 3 In one embodiment, the diameter of the filter hole 10a on the protective body 10 can be preferably 3 to 5 times the average particle size of impurities in the liquid, the total area of ​​the filter hole 10a is greater than 1 / 3 of the area of ​​the drainage port 10d and less than 2 / 3 of the area of ​​the drainage port 10d, and the diameter of the filter hole 10a is not less than 6 mm. It has been found in practice that such a structural design can ensure the accuracy of water quality detection, avoid the influence of excessive impurities on detection, and provide a relatively stable detection environment for the detection sensor, delay the clogging of silt and debris, and keep the inside of the protective part clean for a long time. There is no need to frequently clean the protective part with a brush, which can extend the online time of the hydrological and water quality monitoring equipment and reduce the operation and maintenance costs.

[0038] Main reference Figure 1 In one embodiment, the plurality of filter holes 10a may be evenly distributed along the circumference of the protective body 10, the number of the filter holes 10a may preferably be more than 3, the centers of at least 3 filter holes 10a are located at the same height, and at least 3 filter holes 10a are evenly distributed along the peripheral wall of the protective body 10. In this way, it can be ensured that the inner wall of the detection cavity 10b can be impacted by the water flow, so that the liquid in the detection cavity 10b flows, avoiding the accumulation of impurities in a certain area, and further improving the accuracy of the detection data.

[0039] Reference Figures 1 to 5 In one embodiment, the protective body 10 may be provided with one or more exhaust holes 10e for exhausting the air in the detection chamber 10b. In this way, the air in the liquid in the detection chamber 10b can be exhausted to prevent oxygen from occupying too much space above the detection chamber 10b, resulting in less liquid entering the detection chamber 10b, and the probe 20 cannot detect data, thereby further reducing the measurement error and making the measurement result more accurate.

[0040] In order to allow the air in the measured liquid to be discharged as smoothly as possible and ensure a better exhaust effect, the exhaust hole 10e should be set as high as possible, above the water surface. The exhaust hole 10e of this embodiment can be opened at the end surface of the first end of the protective body 10 and a gap connected to the installation port 10c. Preferably, multiple exhaust holes 10e can be evenly distributed along the circumference of the protective body 10.

[0041] In this embodiment, in order to achieve a better exhaust effect, the diameter of the exhaust hole 10e can be greater than or equal to 3 mm, and the number of the exhaust hole 10e can be more than 3, which is not limited here.

[0042] In addition, in order to improve the convenience of assembly and disassembly of the protective part and the shell of the hydrological and water quality monitoring equipment, so as to facilitate assembly and subsequent maintenance, Figure 1 and Figure 5 In some embodiments, the installation opening 10c of the protection body 10 may be provided with a threaded portion 101 suitable for threaded connection with the housing of the detection sensor. The threaded portion 101 may be an internal thread provided on the inner wall of the installation opening 10c, or an external thread provided on the outer wall of the installation opening 10c. Of course, a clamping portion suitable for clamping and fixing with the housing of the detection sensor may also be provided at the installation opening 10c of the protection body 10. The clamping portion may be a buckle or a clamping groove provided on the outer wall of the installation opening 10c.

[0043] The utility model also provides a hydrological and water quality monitoring device, which includes a detection sensor and a protective member, such as Figure 4 and Figure 5 As shown, the protective body 10 of the protective member is covered on the probe 20 of the detection sensor. The specific structure of the protective member refers to the above-mentioned embodiment. Since the hydrological and water quality monitoring equipment proposed in the utility model includes all schemes of all embodiments of the above-mentioned protective member, it has at least the same technical effects as the above-mentioned protective member, which will not be elaborated here one by one.

[0044] It should be noted that the above-mentioned detection sensors include: one or more of: spectral sensors, pH sensors, conductivity sensors, dissolved oxygen sensors, ammonia nitrogen sensors, total nitrogen sensors, total phosphorus sensors, chlorophyll sensors, algae density sensors, oil in water sensors and residual chlorine sensors.

[0045] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
