[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-4 As shown: A protective cover for a water quality monitoring sensor includes a sensor body 3. A protective mechanism is provided on the outer ring surface of the sensor body 3. The protective mechanism includes a reinforcing sleeve 4, a protective cover body 6, and a sleeve 17. The inner ring surface of the reinforcing sleeve 4 is fixedly connected to the protective cover body 6. The protective cover body 6 and the sensor body 3 are connected by threads. A reinforcing rod 12 is fixedly connected to the inner wall of the protective cover body 6. An internal disk 11 is fixedly connected to one end of the reinforcing rod 12. A telescopic rod 13 is fixedly connected to one side of the internal disk 11. The bottom of the telescopic rod 13 is fixedly connected to a float plate 16. A sleeve 17 is embedded inside the float plate 16. The sleeve 17 is slidably connected to the sensor body 3. An auxiliary disk 14 is fixedly connected to the inner wall of the protective cover body 6. A water inlet hole 15 is opened at the bottom of the auxiliary disk 14, and the auxiliary disk 14 is penetrated by the float plate 16. A sealing ring is fixedly connected to the outer ring surface of the float plate 16. The sealing ring is slidably connected to the inner wall of the protective cover body 6.

[0024] The reinforcing sleeve 4 enhances the strength of the outer ring surface of the protective cover body 6, thereby reducing deformation after impact. The threaded connection between the protective cover body 6 and the sensor body 3 facilitates installation and removal of the protective cover body 6 on the outer ring surface of the sensor body 3. The reinforcing rod 12 reinforces the installation of the internal disk 11. The telescopic rod 13 connects the internal disk 11 and the float 16. The inner and outer rods of the telescopic rod 13 are slidably connected, guiding the rise and fall of the float 16 within the protective cover body 6. To improve the stability of the float plate 16 during lifting and lowering, the sealing ring can improve the sealing effect at the edge of the float plate 16. By connecting the float plate 16 with the auxiliary plate 14, the gap between the auxiliary plate 14 and the sensor body 3 can be sealed and protected when the sensor body 3 is not in use. The water inlet hole 15 facilitates water to enter the protective cover body 6. The buoyancy of the water can be used to adjust the working height of the float plate 16. The sleeve 17 can be used to wrap the outside of the sensor body 3. When the sleeve 17 moves up with the float plate 16, it can reduce the obstruction of the sensor body 3 when it is in use.

[0025] Example 2: Figures 1-3 As shown, a connecting block 7 is fixedly connected to the outer ring surface of the protective cover body 6. A connecting block 10 overlaps the top of the connecting block 7, and a bolt is installed between the connecting block 10 and the connecting block 7. One side of the connecting block 10 is fixedly connected to the positioning ring 8. One side of the positioning ring 8 overlaps with the protective cover body 6, and the other side is inserted into the sensor body 3. A guide 2 is fixedly connected to the top of the sensor body 3. A plug rod 18 is inserted into the bottom of the guide 2. One end of the plug rod 18 passes through the side wall of the sensor body 3 and is fixedly connected to the positioning ring 8. A plug block 5 is fixedly connected to one side of the guide 2. A protective sleeve 9 is inserted into the top of the plug block 5. A connecting piece 1 overlaps the inner wall of the protective sleeve 9. The bottom of the connecting piece 1 is inserted into the guide 2.

[0026] The installation position of the protective cover body 6 outside the sensor body 3 can be defined by connecting block 7 and connecting block 10. The positioning ring 8 can assist the installation of connecting block 10 on the outer ring surface of the sensor body 3. At the same time, the positioning ring 8 can support one end of the plug rod 18. The plug rod 18 can be reinforced by plugging into the guide 2, reducing the loosening of the positioning ring 8. The plug of connecting piece 1 and guide 2 can facilitate the connection of the external power cable to the sensor body 3. The plug of connecting piece 1 and guide 2 can guide the installation of connecting piece 1. The plug of connecting block 5 and protective sleeve 9 can limit the installation of protective sleeve 9. Thus, the protective sleeve 9 can wrap and protect the connection between connecting piece 1 and guide 2, preventing water from entering the gap.

[0027] The usage and working principle of this device are as follows: First, insert the bottom of the connector 1 with the power cord into the guide 2. Then, put the protective sleeve 9 on the connection between the connector 1 and the guide 2, and insert the bottom of the protective sleeve 9 into the plug block 5 to reinforce the connection between the connector 1 and the guide 2. This ensures the connection between the sensor body 3 and the power cord. Place the entire device in water for use. Water enters the inner cavity of the protective cover body 6 through the water inlet 15. The liquid level rises, pushing the float 16 upward along the inner wall of the protective cover body 6. The telescopic rod 13 retracts until the sleeve... The top of tube 17 overlaps with the built-in disk 11, at which point the measuring part of the sensor body 3 can be exposed. The measuring part of the sensor body 3 comes into contact with water to detect water quality. After the detection is completed, the entire device is removed from the water, and the water is discharged from the inlet hole 15. After the float 16 moves down, its bottom is inserted into the through hole of the auxiliary disk 14. When it is necessary to disassemble and replace the protective cover, remove the bolts on the connecting block 1 7 and the connecting block 2 10, rotate the protective cover body 6 to separate the protective cover body 6 from the sensor body 3, and the protective cover body 6 can be replaced separately.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
