When the water flow drives the sensor 9 to collide with the rock, the protective component 2 blocks the collision to prevent the sensor 9 from colliding with the rock.

[0024] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, the protection component 2 includes a first protection frame 201, the first protection frame 201 is movably connected to the second protection frame 202, a wire mesh 206 is provided in the first protection frame 201 and the second protection frame 202, a round hole 205 is provided between the first protection frame 201 and the second protection frame 202, the round hole 205 is adapted to the connecting line 8, two groups of symmetrically distributed plug-ins 203 are provided in the middle position of the outside of the first protection frame 201, the plug-ins 203 are arc-shaped, and a plug-in hole 208 is provided at the center position of the plug-in plate 203, a box body 207 and abutment plate 214 are installed on the second protection frame 202, and the box body The distance between 207 and the plate 214 is adapted to the plug plate 203. A sliding hole 210 is opened on the side of the box body 207. An extrusion plate 209 is slidably connected to the inside of the box body 207. An insertion rod 211 is installed on the side of the extrusion plate 209 facing the plate 214. The insertion rod 211 is adapted to the sliding hole 210 and the insertion hole 208. A connecting rod 213 is installed on the side of the extrusion plate 209 away from the insertion rod 211. A spring 212 is provided on the outer sleeve of the connecting rod 213. One end of the spring 212 is fixedly installed on the surface of the extrusion plate 209, and the other end of the spring 212 is fixedly installed inside the box body 207. 213 is connected to a pull plate 204, which is an arc-shaped setting. The pull plate 204 is slidably adapted to the wire mesh 206, and the connecting line 8 is passed through the round hole 205 on the second protective frame 202. Then, the pull plate 204 on the second protective frame 202 is pulled. The pull plate 204 moves to drive the connecting rod 213 to move. When the connecting rod 213 moves, it drives the extrusion plate 209 to move. The extrusion plate 209 moves to squeeze the spring 212. When the extrusion plate 209 moves, it drives the insertion rod 211 to retract into the box body 207. Then, the insertion plate 203 on the first protective frame 201 is aligned with the plate 214, The position between the box bodies 207 is snapped in (when the first protective frame 201 is snapped in, the round hole 205 is aligned with the connecting line 8. At this time, the first protective frame 201 and the second protective frame 202 snap the connecting line 8 in), and the pull plate 204 is released. Under the rebound action of the spring 212, the insertion rod 211 is driven to insert into the insertion plate 203 to complete the connection. At this time, the protective component 2 is outside the sensor 9. Then the sensor 9 and the protective component 2 are put into the water. The water flows into the sensor 9 through the wire mesh 206, and the water quality is detected by the detection device body 6. The data is displayed on the display screen on the detection device body 6.

[0025] Working principle: When it is necessary to test the water quality, lock the placement box 1 with the box lock 4, then carry the detection device to the drinking water source with the handle 5, open the box cover 3 and take out the detection device body 6, connecting line 8, and sensor 9 (the sensor 9 can be the HWQ500 water quality sensor 9, which is a portable five-in-one water quality sensor 9. It can simultaneously monitor pH value, dissolved oxygen, conductivity, turbidity and temperature, and it can also select additional COD, chlorophyll and cyanobacteria items). Through the setting of the placement box 1 and the box cover 3, it is convenient to put the detection device into the placement box 1, and then the detection device can be conveniently carried to the detection area with the handle 5;

[0026] Then install the protection component 2 on the outside of the sensor 9 to protect the sensor 9. The specific installation method is to pass the connecting wire 8 through the round hole 205 on the second protection frame 202, and then pull the pull plate 204 on the second protection frame 202. The movement of the pull plate 204 drives the connecting rod 213 to move. When the connecting rod 213 moves, it drives the extrusion plate 209 to move. The extrusion plate 209 moves the extrusion spring 212. When the extrusion plate 209 moves, it drives the insertion rod 211 to retract into the box body 207. Then align the insertion plate 203 on the first protection frame 201 with the position between the plate 214 and the box body 207 and snap it in (align the round hole 205 with the connecting wire 8 when the first protection frame 201 is snapped in. At this time, the first protection frame 201 and the second protection frame 202 snap the connecting wire 8 in). Release the pull plate 204, and the spring 212 will rebound to drive the rod 211 to insert into the plug plate 203 to complete the connection. At this time, the protective component 2 is outside the sensor 9. Then the sensor 9 and the protective component 2 are put into the water. The water flows into the sensor 9 through the wire mesh 206, and the water quality is detected by the detection device body 6. The data is displayed on the display screen on the detection device body 6. When the water flow drives the sensor 9 to collide with the rock, the protective component 2 blocks the collision to prevent the sensor 9 from colliding with the rock. The setting of the protective component 2 makes it convenient to protect the sensor 9. When the water flow drives the sensor 9 to collide with the rock, the sensor 9 can be protected to prevent damage to the sensor 9, thereby ensuring the accuracy of the detection data and improving the service life of the sensor 9.
