This invention belongs to the field of seawater monitoring technology, specifically a UAV seawater sampling device with multi-point separation function. Addressing the issue that the inability to separate water samples after sampling prevents multi-point sampling in different areas and necessitates repeated trips, this invention proposes the following solution: a base box with an internally fixed base having four equidistant annular mounting slots. This invention discloses a UAV seawater sampling device with multi-point separation function that can separate and store seawater samples from different areas, enabling multi-point sampling in different regions without repeated trips. Multiple sample storage tubes are installed in an annular and outward-expanding manner, maintaining the base box's center of gravity after sampling (increasing overall weight), ensuring the stability of the UAV flight operation, and preventing the sampled seawater from being concentrated in a single location, causing a shift in the UAV's center of gravity and affecting its flight performance.

The utility model discloses a roll changing device of a calender, which belongs to the technical field of roll changing devices and comprises a frame body and a height adjusting mechanism, movable plates are movably embedded in the inner walls of the two sides of the frame body, a mounting frame is fixedly mounted between the outer walls of the two movable plates, and a mounting shaft is fixedly connected between the inner walls of the two sides of the mounting frame.

Due to the fact that the two ends of the chain are connected with the installation frame and the fixing plate respectively, the installation frame can be conveniently driven to ascend and descend, the calender roller can be conveniently lifted or lowered, the movable plate slides on the inner walls of the two sides of the frame body, the lifting stability of the installation frame is improved, negative effects caused by manual roller replacement are avoided, and the roller replacement efficiency and safety of the calender are improved.

The invention discloses a reef explosion method for underwater karst cave geology, which comprises the following steps of: S1, lowering a drilling sleeve, so that the drilling sleeve is in contact with the surface of rock; s2, a drill rod is put down, and the drill rod drills the rock till the set depth is reached; s3, releasing the connection between the drilling machine and the drilling rod; s4, putting a chemical feeding sleeve between the drill rod and the drill hole sleeve; s5, the drill rod is connected with the drilling machine, and the drill rod is lifted; s6, the explosive is put down through the explosive feeding sleeve; and S7, the drilling casing pipe and the chemical feeding casing pipe are lifted, and blasting is carried out. When drilling is completed, connection between the drill rod and the drilling machine is removed, the drill rod serves as a guide rod for lowering of the chemical feeding sleeve, the chemical feeding sleeve can be conveniently inserted into a hole below a karst cave, the drilling sleeve can limit the drill rod, the possibility that the drill rod topples over is avoided, and the drilling diameter of the drill rod is generally larger than the diameter of a drill bit. A certain gap exists between the drill bit and the hole, the chemical feeding sleeve is placed through the gap, and accurate placing of the chemical feeding sleeve can be achieved without increasing cost.
