Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1This utility model provides a technical solution: a self-cleaning digital dissolved oxygen sensor device, including a device body 1. The device body 1 includes a junction box 2, a sensor storage rod 3, a quick connection device 4, and a sensor protection device 5. The sensor storage rod 3 is installed on the top of the junction box 2, the quick connection device 4 is located on the top of the sensor storage rod 3, and the sensor protection device 5 is installed on the top of the quick connection device 4.

[0019] The solution is that the quick connection device 4 includes a large mounting cap 6 and a threaded mounting cap 7. The large mounting cap 6 and the threaded mounting cap 7 are smoothly transitioned and integrally formed. The large mounting cap 6 is located at the bottom of the threaded mounting cap 7. The large mounting cap 6 and the sensor storage rod 3 are smoothly transitioned and integrally formed.

[0020] Furthermore, the threaded mounting cap 7 includes a large threaded connecting sleeve 8 and a small threaded connecting sleeve 9. The large threaded connecting sleeve 8 is located at the bottom of the small threaded connecting sleeve 9. The large threaded connecting sleeve 8 and the small threaded connecting sleeve 9 are smoothly transitioned and integrally formed. The diameter of the large threaded connecting sleeve 8 is larger than the diameter of the small threaded connecting sleeve 9. The surfaces of the large threaded connecting sleeve 8 and the small threaded connecting sleeve 9 are provided with several sets of mounting threads 14. The large threaded connecting sleeve 8 and the small threaded connecting sleeve 9 inside the threaded mounting cap 7 are for connecting threaded sleeve caps 10 of different sizes and models, thereby improving the applicability of the equipment and facilitating the connection of sensor protection devices 5 of different sizes.

[0021] Unlike other sensors, the sensor protection device 5 includes a threaded cap 10, a storage cylinder 11, and a protective block 12. The threaded cap 10, storage cylinder 11, and protective block 12 are all smoothly transitioned and integrally formed. The threaded cap 10, storage cylinder 11, and protective block 12 have a through-type internal structure. The threaded cap 10 is located at the bottom of the storage cylinder 11, and the protective block 12 is located at the top of the storage cylinder 11. The protective block 12 has a funnel-shaped structure, and a protective cover 13 is provided on the top of the protective block 12. During use, the sensor is stored inside the protective cover 13, thus protecting the sensor from external contamination. When collecting external information, if the sensor protection device 5 needs to be disassembled or installed, the operator puts the threaded socket cap 10 on the sensor protection device 5 onto the threaded mounting cap 7, and then rotates the threaded socket cap 10 to install the sensor protection device 5 as a whole on the quick connection device 4. If disassembly is required, the operator rotates the threaded socket cap 10 in the opposite direction, and then the sensor protection device 5 on the connection device 4 can be removed. The sensor protection device 5 can protect the internally detected sensor from corrosion, impact and contamination.

[0022] Effectively, the bottom of the junction box 2 has a trapezoidal structure, and the left and right sides of the bottom of the junction box 2 are provided with wire inlet notches 15. The wire inlet notches 15 have an n-shaped structure. The junction box 2 is for storing electronic components, and the wire inlet notches 15 on the side of the junction box 2 can facilitate the insertion of wires and then make connections.

[0023] Working principle: During operation, when it is necessary to disassemble or install the sensor protection device 5, the operator puts the threaded socket cap 10 on the sensor protection device 5 onto the threaded mounting cap 7, and then rotates the threaded socket cap 10 to install the sensor protection device 5 as a whole onto the quick connection device 4 (the large threaded connecting sleeve 8 and the small threaded connecting sleeve 9 inside the threaded mounting cap 7 are for connecting threaded socket caps 10 of different sizes and models, thereby improving the applicability of the equipment and facilitating the connection of sensor protection devices 5 of different sizes). If disassembly is required, the operator rotates the threaded socket cap 10 in the opposite direction, and then the sensor protection device 5 on the connection device 4 can be removed. The sensor protection device 5 can protect the internal sensor from corrosion, impact and contamination.
