DETAILED DESCRIPTION

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

As shown in FIG. 1 and FIG. 2 , a water sampling device for water quality testing includes a sampling bucket 1 , a hanging ring 2 , a pull rope 3 , a plurality of partitions 4 , a plurality of water inlets 5 , a plurality of water outlets 6 , a plurality of one-way valves 7 and an opening and closing mechanism 8 .

As shown in Fig. 1 and Fig. 2, the sampling bucket 1 is used to hold water samples, the hanging ring 2 is arranged at the upper end of the sampling bucket 1, and the pull rope 3 is fixed on the hanging ring 2. A plurality of partitions 4 are arranged horizontally and at intervals in the sampling bucket 1, and divide the sampling bucket 1 into a plurality of independent areas 41.

As shown in Fig. 1 and Fig. 2, a plurality of water inlets 5 are arranged at intervals on the side wall of the sampling barrel 1, and are respectively connected to a plurality of independent areas 41. A plurality of water outlets 6 are arranged at intervals on the side wall of the sampling barrel 1, and are respectively connected to a plurality of independent areas 41. A plurality of one-way valves 7 are arranged in the water inlet 5, and are used to supply water into the independent area 41. The opening and closing mechanism 8 is used to control the opening and closing of the plurality of one-way valves 7 in sequence from bottom to top.

As shown in Fig. 1 and Fig. 2, the one-way valve 7 comprises a valve tube 71, a valve stem 72, a valve plate 73, a valve head 74 and a spring 75. The valve tube 71 is embedded in the water inlet 5 and is provided with a through hole 76 horizontally therethrough. The valve stem 72 is horizontally slidably connected to the valve tube 71, and the valve plate 73 is provided at the inner end of the valve stem 72 and is used to cover the through hole 76. The valve head 74 is spherically provided at the outer end of the valve stem 72, and the spring 75 is sleeved on the valve stem 72 and is located between the valve head 74 and the valve tube 71.

As shown in Fig. 1 and Fig. 2, the opening and closing mechanism 8 includes a switch rod 81 and a switch block 82. The switch rod 81 is vertically slidably connected to the side wall of the sampling barrel 1 and is aligned with the multiple one-way valves 7. The switch block 82 is arranged on the side wall of the switch rod 81, is spherically arranged, and is used to press the valve head 74.

When the water sampler is needed to collect water samples, firstly, vacuum is drawn in the independent area 11 through the water outlet 6, and the sampling bucket 1 is put into the water sample, and the sampling bucket 1 is controlled to settle under the action of the counterweight 91. Then, the pull rope 3 is pulled to lift the sampling bucket 1 to realize the water sample collection operation.

When the sampling bucket 1 is placed in the water sample, the sampling bucket 1 will gradually sink downward. At the same time, the opening and closing mechanism 8 can be used to control multiple one-way valves 7 to open and close in sequence from bottom to top, so that water samples of different depths can be poured into each independent area 41, thereby realizing continuous sampling and one-time sampling of water samples of different depths, making the sampling process more convenient.

When the sampling barrel 1 sinks, the switch rod 81 is pulled to drive the switch block 82 to move upward. At this time, the switch block 82 presses the valve head 74 to move inward, and the valve head 74 drives the valve stem 72 and the valve plate 73 to move synchronously, so that the valve plate 73 is disengaged from the through hole 76, thereby realizing the opening control of the one-way valve 7 and realizing automatic sampling of water samples at different depths.

As shown in Fig. 1 and Fig. 2, the lower end surface of the sampling bucket 1 is provided with a hanging rope 9, and a counterweight 91 is provided on the hanging rope 9. By providing the counterweight 91, the sampling bucket 1 can be stably and quickly sunk into the deep water, making the sampling process more convenient.

As shown in FIG. 1 and FIG. 2 , the counterweight block 91 is arranged in a cone shape. By arranging the counterweight block 91 in a cone shape, the resistance of the water sample to the counterweight block 91 is reduced, thereby ensuring the stable sedimentation of the sampling barrel 1 .

As shown in Fig. 1 and Fig. 2, a mounting rod 92 is provided on the suspension rope 9, the mounting rod 92 penetrates the counterweight 91, and an elastic hook 93 is provided at the lower end of the mounting rod 92 for hooking the lower end surface of the counterweight 91. By providing a detachable and conveniently detachable counterweight 91, the replacement process of counterweights 91 of different weights is more convenient.

The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
