[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] As shown in the figure, this embodiment provides an unmanned ship hydrological sampling detection device, including a hull 1 and a carrier 2 fixed on the hull 1, a mounting bracket 3 is fixedly installed on the carrier 2, a sleeve 9 is fixedly installed on one side of the mounting bracket 3, a sampling tube 6 is slidably connected in the sleeve 9, and the sampling tube 6 is driven by a hydraulic cylinder 7 to achieve rising and falling; for specific installation methods, refer to Figure 1 and Figure 2As shown, a side column 4 is fixedly mounted on one side of the mounting bracket 3 for fixing a mounting sleeve 9, wherein a hydraulic cylinder 7 is mounted on the side of the side column 4 away from the mounting sleeve 9. The lower base portion of the hydraulic cylinder 7 is hinged to the side column 4, and a connecting rod is hinged to the upper end of the piston rod of the hydraulic cylinder 7, and one end of the connecting rod is hinged to the sampling tube 6.

[0020] A valve 62 is installed at the bottom of the sampling tube 6. The valve 62 can be a diaphragm check valve or a solenoid valve. The check valve can be automatically controlled to open and close. The solenoid valve can be electrically controlled to open when pumping water and close when drawing water. A check valve 61 is arranged on the outer wall of the sampling tube 6. A pumping valve is arranged at a position corresponding to the check valve 61 on the sleeve 9. The valve core 51 of the pumping valve protrudes from the inner wall of the sleeve 9. When the sampling tube 6 moves up and down, the valve core 51 abuts against the check valve 61, and the check valve 61 is opened. One end of the pumping valve is connected to the sampling bottle 5.

[0021] Structural reference of pump valve Figure 3 as well as Figure 4 As shown, the water pump valve comprises an outer chamber 52, an inner chamber 54 and a valve stem 55, a valve core 51 is fixed at the end of the valve stem 55, a valve plate 53 is arranged inside the valve core 51, a spring 56 is sleeved on the valve stem 55, one end of the spring 56 abuts against the valve stem 55, and the other end abuts against the inner end wall of the inner chamber 54, so that the spring 56 acts on the valve stem 55, and the valve stem 55 has a tendency to extend outward, the outer diameter of the outer chamber 52 is larger than the valve core 51, and a water groove is arranged on the outer surface of the valve core 51.

[0022] Reference Figure 3 and Figure 4 As shown, during the process of pumping and drawing water, the outer wall of the sampling tube 6 presses the valve core 51, and the valve plate 53 tightly covers the inlet of the inner chamber 54, and the pumping valve remains closed. When the sampling tube 6 slides to a specific position, as shown in FIG. Figure 4 The position shown in the figure can be opened inwards due to the one-way valve 61. The one-way valve 61 can also adopt a spring-type one-way valve structure. For example, a spring is used behind the valve core of the one-way valve 61 to make it abut against the valve port and close it. When the outside is pressed inwards, it can be opened. When designing, it only needs to design the spring force of the pumping valve to be greater than the spring force of the one-way valve to achieve this effect.

[0023] Reference Figure 4 When the one-way valve 61 is opened, water can flow into the pumping valve. On this basis, a vacuum sampling bottle 5 is used to quickly suck in water through negative pressure.

[0024] Reference Figure 2As shown, multiple one-way valves 61 and corresponding pumping valves and sampling bottles 5 are provided, and layered use can be achieved along different heights. It is worth mentioning that different one-way valves 61, pumping valves and sampling bottles 5 need to be provided along different circumferential directions so that they can be triggered simultaneously.

[0025] The sampling bottle 5 and the pumping valve can be fixed by threaded connection, which is also convenient for subsequent extraction on shore.
