[0025] Refer to the attached Figure 1 The embodiment of the present application provides a water quality monitor, including a monitor host 1 and a probe 3. The monitor host 1 is connected to the probe 3 via a data cable 2. The probe 3 is threadedly fixed in a protective shell 4. A water inlet 9 is provided on the protective shell 4. When monitoring water quality, water quality enters the protective shell 4 through the water inlet 9 and is collected by the probe 3.

[0026] A baffle 8 is provided at the water inlet 9, and an adjustment component 7 is provided inside the protective shell 4. The adjustment component 7 is connected to the baffle 8, and the adjustment component 7 can adjust the baffle 8 to open and close the water inlet 9. It can be imagined that in specific implementation, the baffle 8 is adjusted by the adjustment component 7 to open the water inlet 9, and the probe 3 is placed in the water area to be tested. During the descent of the probe 3, the protective shell 4 is used to protect the probe 3 from being damaged by collision with foreign objects. At the same time, the water quality can enter the protective shell 4 from the water inlet 9 and be monitored by the probe 3. After obtaining the monitoring results, the protective shell 4 is lifted out of the water, and the baffle 8 is adjusted by the adjustment component 7 to close the water inlet 9, and the protective shell 4 is used to wrap the probe 3, so as to prevent the probe 3 from being accidentally damaged.

[0027] It should be noted that the above-mentioned monitoring instrument host 1 and probe 3 are both existing technologies and are not described in detail here. Of course, a water leakage hole 10 can be optionally provided at the bottom of the protective shell 4, so that when the probe 3 and the protective shell 4 are lifted out of the water, the water in the protective shell 4 is released through the water leakage hole.

[0028] In a preferred embodiment, see Figure 2 As shown, the adjustment assembly 7 includes a shaft 701, a light rod 702, a slide seat 703 and a push rod 704. The shaft 701 is rotatably arranged in the protective shell 4, and the shaft 701 extends downward out of the protective shell 4. A handle 705 is arranged at one end of the shaft 701 outside the protective shell 4. The shaft 701 and the protective shell 4 are connected by a bearing, and the shaft 701 can be rotated by the handle 705. The light rod 702 is fixed to the inner bottom surface of the protective shell 4 and is parallel to the shaft 701. The shaft 701 is symmetrically provided with threads in opposite directions on both sides of the midpoint. The two ends of the shaft 701 are provided with slide seats 703. A guide sleeve is integrally formed on the slide seat 703. The guide sleeve is slidably connected to the light rod 702. Each slide seat 703 is hinged with a push rod 704 through a pivot, and the push rod 704 is hinged with the baffle 8 through a pivot. It can be imagined that by rotating the shaft 701 through the turning handle 705, the slide 703 can approach in the same direction and move away in the opposite direction. When the slide 703 approaches in the same direction, the baffle 8 is pushed outward by the push rod 704 to open the water inlet 9. When the slide 703 moves away in the opposite direction, the baffle 8 is pulled inward by the push rod 704 to block the water inlet 9.

[0029] In the above, the bottom of the protective shell 4 is connected to the buffer plate 5 through the spring 6. The buffer plate 5 has a certain weight, so that when the protective shell 4 is falling, the buffer plate 5 always brings the protective shell 4 and the probe 3 down. It is not difficult to imagine that when the protective shell 4 is falling with the probe 3, the buffer plate 5 brings the protective shell 4 and the probe 3 down, so that the buffer plate 5 first contacts the foreign object, and after the buffer plate 5 contacts the foreign object, the impact is mitigated by the spring 6, so that the impact force on the protective shell 4 is greatly reduced, which is more conducive to protecting the probe 3.

[0030] In this embodiment, the protective shell 4 includes a first shell 401 and a second shell 402, and the first shell 401 and the second shell 402 are detachably connected, such as the first shell 401 and the second shell 402 are threadedly connected. A threaded hole is provided on the top side of the first shell 401, and the probe 3 is threadedly installed in the threaded hole, and the water inlet 9 is provided in the second shell 402. Based on the detachable structure of the protective shell 4, it can be imagined that after completing the water quality monitoring, the probe 3 is lifted out of the water, the first shell 401 and the second shell 402 are separated, and the probe 3 is rinsed and cleaned to prevent the residue of the previous measurement from affecting the next measurement, and at the same time, the rust of the probe 3 can be reduced.

[0031] In the above, a perforated partition 11 is provided on the inner wall of one side of the second shell 402 close to the first shell 401, the bottom of the shaft 701 is connected to the bearing of the protective shell 4, the top of the shaft 701 is connected to the bearing of the perforated partition 11, and the top surface of the perforated partition 11 is provided with a mounting groove, and a filter assembly 12 is placed in the mounting groove. Among them, the filter assembly 12 includes a filter screen and a mesh frame, and the filter screen is placed in the mesh frame. By setting a filter screen between the first shell 401 and the second shell 402, during the monitoring and collection process, the water quality enters the first shell 401 from bottom to top through the holes of the perforated partition 11. Due to the existence of the filter screen, garbage, aquatic plants and the like are filtered, thereby avoiding the trouble of the probe 3 being entangled by foreign objects such as garbage and aquatic plants.

[0032] Furthermore, a plurality of stoppers 13 located on the surface of the mounting groove are provided circumferentially on the inner wall of one side of the first housing 401 close to the second housing 402. It is conceivable that after the first housing 401 and the second housing 402 are assembled, the filter assembly 12 is restricted in the mounting groove by the design of the baffle 8, thereby preventing the filter assembly 12 from floating due to the buoyancy. At the same time, after the first housing 401 and the second housing 402 are disassembled, the baffle 8 is separated from the mounting groove, and the filter net can be taken out for cleaning or replacement, which is very convenient.

[0033] In summary, the water quality monitor provided in the embodiment of the present application has the following usage method:

[0034] Disassemble the protective shell 4, check whether the filter is intact and whether there are foreign objects. After the inspection, assemble the first shell 401 and the second shell 402, turn the shaft 701 by turning the handle 705, move the baffle 8 outward to open the water inlet 9, and then put the protective shell 4 and the probe 3 into the water area to be tested. During the descent, the water quality enters the second shell 402 through the water inlet 9, and then enters the first shell 401 from the filter through the perforated partition 11 to be collected by the probe 3. After the monitoring results are obtained, lift the protective shell 4 and the probe 3 out of the water, disassemble the protective shell 4 to rinse and clean the filter and the probe 3, and finally assemble the first shell 401 and the second shell 402 into one body, and turn the shaft 701 to move the baffle 8 inward to close the water inlet 9.

[0035] It can be seen that by arranging the probe 3 in the protective shell 4, the protective shell 4 can protect the probe 3 during the measurement and descent process to avoid damage due to collision. At the same time, since the protective shell 4 is provided with a water inlet 9, a baffle 8 is provided at the water inlet 9. The baffle 8 can open the water inlet 9 under the adjustment of the adjustment component 7, so that water quality enters the protective shell 4 and is collected by the probe 3, so that the water quality monitoring work can be successfully completed. Enclosing the probe 3 in the protective shell 4 can also prevent the probe 3 from being accidentally damaged when not in use.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
