[0014] Beneficial effects

[0015] The present invention facilitates the disassembly and assembly of the installation detection inner shell and the sensor mounting seat through the setting of the disassembly and assembly mechanism. After the installation detection inner shell is slidably connected to the inside of the buffer silicone tube, the installation plug is inserted into the central circular hole of the sliding limit plate. At this time, the limit slider will pop out and be stuck on the outside of the sliding limit plate under the action of the reset compression spring, thereby completing the fixation of the installation detection inner shell. The setting of the buffer silicone tube can effectively absorb external impact force. When the protective detection shell is hit, the buffer silicone tube will play a buffering role to avoid damage to the electronic components in the installation detection inner shell caused by rigid impact. When it is necessary to disassemble When installing the detection inner shell, you only need to remove the sealing end cover and insert the disassembly cylinder into the outside of the installation plug-in block, then press the sealing end cover, the disassembly cylinder will squeeze the limit slider to retract it into the installation plug-in block. At this time, the sliding extrusion piece will push the installation plug-in out of the sliding limit piece under the action of the disassembly compression spring, thereby completing the disassembly operation. When the detection sensor needs to be replaced, you only need to toggle the fixed paddle, and the fixed paddle will drive the limit plug-in to detach from the sensor mounting seat, thereby realizing the rapid disassembly of the sensor mounting seat and the detection sensor. The operation is simple and efficient, which improves work efficiency and reduces labor intensity.

[0016] In addition, through the setting of the detection and cleaning mechanism, the flushing of the detection sensor and the fixed filter is achieved. When the cleaning water pump is started, it draws water through the water inlet pipe, and the fixed filter will filter the impurities in the water. The liquid drawn by the cleaning water pump is transported to the connecting disk through the outlet pipe, and then flows into the fixed cleaning rod through the connecting pipe, and is finally sprayed out by the fixed cleaning rod to clean the detection sensor, effectively removing floating objects attached to the sensor surface, ensuring the accuracy and stability of data collection. At the same time, the liquid in the connecting disk will be sent to the fixed cleaning head through the cleaning pipe, and sprayed out by the fixed cleaning head to flush the fixed filter to prevent the filter from being blocked and ensure the normal operation of the equipment.

[0017] In addition, through the setting of the above-mentioned mechanism, not only the convenient disassembly and assembly of the detection inner shell and the sensor mounting seat is achieved, thereby improving maintenance efficiency, but also the problem of floating object obstruction is effectively solved through the automatic cleaning function, providing reliable guarantee for the long-term stable operation of the deep-sea ecological detection device.
