Preferably, the second limiting portion 6 is provided with notches at the peripheral edge, the notches and the inner wall of the barrel 2 form a water inlet for water to pass through, and the outer diameter of the second sealing member 7 is smaller than the inner diameter of the barrel 2, so that the second sealing member 7 cannot completely block water flow during movement, and the water flow can smoothly enter the barrel 2.

The barrel body 2 is made of transparent glass, is easy to clean and is resistant to acid and alkali corrosion. A water outlet is formed in the side wall of the lower end of the barrel body 2, the water outlet is connected with a water outlet hose 8, the water outlet hose 8 is knotted during sampling, and the water outlet hose 8 is untied when water needs to be drained. The upper half part of the cylinder body 2 is provided with a handle 9, the handle 9 and the water outlet hose 8 are positioned at the opposite sides of the cylinder body 2, and the cylinder body 2 is inclined when the handle 9 is lifted, so that water in the cylinder body 2 is conveniently discharged from the water outlet hose 8.

When sampling, the water quality detection sampler is fixed on a long rod for use. Referring to fig. 1 and 2, a throat hoop 10 is provided at the upper end of the barrel 2, a radial screw 11 with a knob is screwed on the throat hoop 10, the inner end of the screw 11 faces the outer wall of the throat hoop 10, the size of the gap between the inner end and the outer wall of the throat hoop 10 can be adjusted by rotating the screw 11, and the long rod passes through the gap between the inner end of the screw 11 and the outer wall of the throat hoop 10 and is locked by the screw 11. The lower end of the cylinder body 2 is provided with an elastic holding piece 12, the elastic holding piece 12 is positioned below the screw 11, the elastic holding piece 12 is provided with a vertical elastic limiting hole, and the lower end of the long rod is clamped into the elastic limiting hole of the elastic holding piece 12 so as not to rotate. As shown in FIG. 1, the elastic clasping piece is a metal open ring with two ends not connected with each other.

When needing to discharge the water in the barrel 2, the screw 11 of unscrewing takes out the lower extreme of stock from the spacing hole of elasticity, need not to take off the stock from barrel 2 completely, and rotatory stock can be later with the slope of barrel 2 and untie the water in the water hose 8 and can discharge barrel 2. The lower end of the long rod is clamped into the elastic limiting hole and the screw 11 is screwed, so that the long rod is reset, the operation is convenient, and the operation efficiency is improved.
