[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the utility model includes a box body 7 and a filter assembly, wherein a push-and-pull filter assembly is sealed and installed on the box body 7, and the filter assembly includes a carrier net 4 and filter cotton. The carrier net 4 can be pushed and pulled relative to the box body 7, and the filter cotton is attached to the carrier net 4. The filter accuracy of the processing device can be changed by replacing the filter cotton on the carrier net 4; a pagoda water inlet 2 with a switch and a pagoda plug 3 are respectively provided on the box body 7 above the filter assembly, and a pagoda water outlet A5 with a switch and a pagoda water outlet B6 with a switch are respectively provided on the box body 7 below the filter assembly.

[0022] The box 7 of this embodiment is a vertical flat water tank (i.e., a rectangular parallelepiped water tank) with a length of 32 cm, a width of 20 cm, a height of 36 cm, and an inner wall thickness of 2 cm. The box 7 is small in size, light in weight, and easy to carry; moreover, it does not require electricity, and relies on the height difference of the water flow to achieve filtration, which is economical and environmentally friendly.

[0023] The pagoda water inlet 2 with switch, the pagoda water outlet A5 with switch and the pagoda water outlet B6 with switch in this embodiment are all pagoda ball valves of the prior art. The pagoda water inlet 2 with switch is arranged on the top surface of the box 7, connected to the faucet on the ship, and used for water intake, and adopts a 4-point ball valve single-side pagoda socket of 12 mm. The pagoda water outlet A5 with switch in this embodiment is arranged on the side of the bottom of the box 7, and is used for drainage, and adopts a 4-point ball valve single-side pagoda socket of 12 mm; the pagoda water outlet B6 with switch is arranged on the front of the bottom of the box 7, and is used to be connected to the instrument sample injection tube to convey the filtered seawater, and adopts a 4-point ball valve single-side pagoda socket of 6 mm. By adjusting the switches of the three ball valves, the volume of seawater in the box 7 is placed in a relatively stable position.

[0024] The top surface of the box body 7 of this embodiment is also provided with a circular threaded opening 1 for communicating with the atmosphere, balancing the pressure of the box body 7 with the external pressure, and ensuring that water can flow into the box body 7; the diameter of the opening 1 may be 20 mm.

[0025] In this embodiment, a strip opening (rectangular opening) is provided on the side of the box body 7, and the strip opening is 30 cm long and 3 cm high; three U-shaped card slots are installed on the inner wall of the box body 7 at the same height as the strip opening, and the U-shaped card slots are made of plastic. The carrier net 4 is inserted from the strip opening and slidably connected with the U-shaped card slots, so that the carrier net 4 can be embedded and can be extracted and replaced, and has a good sealing effect when water flows down in the box body 7, and will not let the water flow out of the box body 7; and the setting of the U-shaped card slot can make the carrier net 4 plug and play. If you need to replace a filter component with other filtering precision, you can quickly pull out and insert a new filter component, which is convenient and quick.

[0026] The bearing net 4 of this embodiment is composed of four rectangular plastic strips that can fit into the U-shaped slot, and the middle can be filled with filter cotton of different filtering precisions as needed. This embodiment makes four filter components with different filtering precisions, namely 10 microns, 50 microns, 100 microns, and 200 microns. The filtering precision of the filter component can be customized according to the needs of use later. The pagoda plug 3 of this embodiment is arranged on the side of the box body 7, that is, there is an opening on the box body 7 above the strip mouth, which is plugged with the pagoda plug 3, and the diameter of the pagoda plug 3 can be 15 mm; when the water flow in the box body 7 suddenly increases or the filter component is blocked, causing too much water to accumulate in the box body 7, the water that is about to overflow in the box body 7 is discharged by opening the pagoda plug 3.

[0027] The working principle of the utility model is:

[0028] Connect the pagoda water inlet 2 with a switch to the faucet for extracting seawater pump on board through an elastic hose and lock it. Connect the pagoda water outlet A5 with a switch to the instrument with an elastic hose and lock it. Connect the pagoda water outlet B6 with a switch with an elastic hose and lock it, then introduce it into the drainage well or other water outlet on board. Tighten the pagoda plug 3 and do not open it unless necessary. Determine the seawater filtration accuracy required by the instrument, and insert the carrier net 4 with filter cotton of corresponding filtration accuracy into the strip opening on the side of the box 7. Turn on the faucet on board, and adjust the switches of the pagoda water inlet 2 with a switch and the pagoda water outlet A5 with a switch and the pagoda water outlet B6 with a switch at the same time, so that the seawater content in the box 7 is in a stable position and cannot exceed the position of the carrier net 4. After setting, the box 7 starts to work. When the filter cotton on the carrier net 4 is blocked or other filter components with filtration accuracy need to be replaced, turn off the faucet on board, and do not move the others. Pull out the previous carrier net 4, insert the new filter component, turn on the faucet again, and continue working. When the work is completed, remove the hose between the pagoda water inlet 2 with a switch and the faucet on the ship, remove the hose between the pagoda water outlet A5 with a switch and the instrument, remove the hose between the pagoda water outlet B6 with a switch and the drainage well on the ship, and move the box 7 as a whole.
