The rotation of the U-shaped rod pushes the deposits on the top of the separation plate and inside the water inlet frame. The U-shaped rod pushes and wipes the deposits, which can effectively break and loosen stubborn stains and sediments, thereby improving the separation effect of the separation plate on solid particles in the water body before water quality detection.

The adjustment pipe is manually pushed to move to a suitable length and docked with the sewage recovery device. By adjusting the length of the adjustment pipe, the stability of the docking between the adjustment pipe and the sewage recovery device can be ensured. The stable docking can ensure that the sewage generated by flushing is effectively recovered during the backwashing process without leakage or backflow problems, further ensuring the accuracy of water quality detection.

[0016] (3) In the water quality detection device with backwashing function, part of the cleaning liquid at the top of the control frame enters the water inlet frame through the conduit. The quantitative input of the cleaning liquid can ensure that the cleaning dosage used in each backwashing process is accurate, thereby improving the efficiency of cleaning oily substances during backwashing and preventing the oily substances from affecting the water quality measurement results. The curved plate recovers under the action of its own elastic force and pushes the cleaning liquid inside the load-bearing frame. The recovery of the curved plate under the action of its own elastic force can generate periodic thrust, which helps to maintain uniform mixing of the cleaning liquid and prevent liquid layer separation, thereby improving the efficiency and effect of backwashing.

[0029] When the present embodiment is working, the L-shaped rack 9 moves toward the direction close to the detection device 2, contacts the inclined surface of the cross plate 154 and squeezes the cross plate 154. The cross plate 154 moves upward due to the squeezing of the L-shaped rack 9. The cross plate 154 moves upward to pull the No. 1 spring. The No. 1 spring is pulled by the cross plate 154 to deform and accumulate force. At the same time, the cross plate 154 moves upward to release the seal of the sewage pipe 151. After the seal of the sewage pipe 151 is released, the sewage generated by the backwashing device 8 can be discharged through the sewage pipe 151 and the regulating pipe 152. When the L-shaped rack 9 moves to reset in the direction away from the detection device 2, the L-shaped rack 9 moves to reset in the direction away from the detection device 2 and disengages from the contact with the cross plate 154. After the cross plate 154 disengages from the contact with the L-shaped rack 9, the cross plate 154 moves downward to reset under the elastic force of the No. 1 spring. The cross plate 154 moves downward to reset and restores the seal of the sewage pipe 1 51 is sealed, and the sewage pipe 151 is sealed by the cross plate 154 to ensure that the sewage pipe 151 will not leak when the water enters the detection frame 1. When the docking length of the sewage pipe 151 needs to be adjusted, first manually push the free end of the elastic telescopic block 159 to move upward, and the free end of the elastic telescopic block 159 moves upward to break away from the contact with the T-shaped adjusting rod 158 and release the limit on the T-shaped adjusting rod 158. After the limit of the T-shaped adjusting rod 158 is released, manually pull the T-shaped adjusting rod 158 to move forward. The T-shaped adjusting rod 158 moves forward to pull the No. 2 spring.

[0030] The cross plate 154 moves upward, driving the linkage plate 1510 to move upward. The linkage plate 1510 moves upward, contacts the control rod 163 and squeezes the control rod 163. The control rod 163 moves upward due to the squeezing of the linkage plate 1510. The control rod 163 moves upward, driving the control plate 164 to move upward. The control plate 164 moves upward to squeeze the No. 3 spring. The No. 3 spring is squeezed by the control plate 164 and deforms. At the same time, the control plate 164 moves upward to break away from the contact with the liquid inlet hole 165 and seals part of the cleaning liquid on the top of the control frame 162. The control plate 164 continues to move upward to squeeze part of the cleaning liquid on the top of the control frame 162. Part of the cleaning liquid on the top of the control frame 162 is squeezed by the control plate 164 and enters the inside of the conduit 166. The cleaning liquid entering the conduit 166 squeezes the rubber block, and the rubber The block is deformed by the squeezing of the cleaning liquid entering the conduit 166, and the rubber block is deformed and releases the seal of the conduit 166. After the seal of the conduit 166 is released, part of the cleaning liquid at the top of the control frame 162 enters the water inlet frame 4 through the conduit 166. When the control rod 163 is squeezed and moved upward by the linkage plate 1510, the control rod 163 moves upward and contacts with the curved plate 167 and squeezes the curved plate 167. The curved plate 167 is deformed by the squeezing of the control rod 163. When the control plate 164 and the control rod 163 move downward and reset under the elastic force of the No. 3 spring, the control rod 163 moves downward and resets to break away from the contact with the curved plate 167. After the curved plate 167 breaks away from the contact with the control rod 163, the curved plate 167 recovers under the action of its own elastic force and pushes the cleaning liquid inside the load-bearing frame 161.
