Problems solved by technology

The water samples collected are more than required, and the impurities in the water will precipitate rapidly in the sampler, causing the supernatant to be mixed down, thus affecting the analysis and test results, and also increasing the labor intensity
The water collection rope becomes longer under stress, which also affects the accuracy of sampling
The sampler is impacted by the water flow during use, and the water collection rope is easy to knot

Embodiment 1

[0019] Embodiment one: if figure 1 As shown, a kind of water sample sampler provided by the present invention comprises a barrel body 8 with a through-tube structure, a support 13 is provided at the bottom of the barrel body 8, and a water outlet 21 is provided at one side of the barrel body 8. A water outlet switch 10 is connected to the water outlet 21. The upper end of the barrel body 8 is provided with a water outlet 8.1, and the lower end is provided with a butterfly-shaped water inlet 8.3. The butterfly-shaped water inlet 8.3 can make the water intake smooth. The body 8 includes an upper barrel wall 14 of a cylindrical structure, and is adjusted and fixedly connected to a lower barrel wall 14.2 on the lower side of the upper barrel wall 14 through a connecting piece 9. The connecting piece 9 adopts bolts and locks that cooperate with each other. Tighten the nut. The upper end of the upper barrel wall 14 is inwardly provided with an annular upper flap 8.2, and the lower ...

Embodiment 2

[0023] Embodiment two: if figure 2 As shown, the rotating shaft connecting the lower cover plate 12 in the embodiment is arranged above the lower folding plate 8.4, and a lower cover plate 12 is connected with the rotating shaft on the rotating shaft, and an L-shaped folding plate 8.4 is also connected. The gear lever 18 is connected to the end of the L-shaped gear lever 18 with a stopper 19 matched with the gear of the lower cover plate 12 .

[0024] When in use, one end of the cable 1 is fixed on the pile of the ship, the other end of the rope swivel 7, the water outlet switch 10 is closed, and the counterweight rope 16 is connected to the counterweight 17 and the bucket body 8, and the bolt and lock of the connecting part 9 are adjusted. Tighten the nut to control the water intake. When water is collected, the water collector is slowly put into the water, the water inlet 8.3 and the outlet 8.1 are automatically opened, and the required water depth is displayed according to...

Abstract

The invention relates to a water sampler, which comprises a bucket body, wherein the bucket body is composed of an upper side bucket wall and a lower side bucket wall; a water outlet is formed in the upper end of the bucket body; a water inlet is formed in the lower end of the bucket body; an upper folding plate is arranged at the upper end of the upper side bucket wall; a lower folding plate is arranged at the lower end of the lower side bucket wall; an upper cover plate correspondingly matched with the upper folding plate is rotatably connected to the water outlet; a lower cover plate correspondingly matched with the lower folding plate is rotatably connected to the water inlet; a cable is connected onto the outer bucket wall through a semi-circular handle; a water depth display is connected to the cable; a rotating shaft is connected with the lower cover plate; a balancing weight is connected onto the rotating shaft through a balancing weight rope. The water sampler has the advantages that the volume of the bucket body is adjustable; the water sampler has no hindrance in water intake and discharge, is capable of ensuring an accurate water sample, has time-saving and labor-saving effects, is light in weight, convenient to operate, intuitive in water sampling, low in manufacture cost, portable and suitable for field sampling work and can be widely applied to water sampling of different water fields; the quality of sampled water and test results are improved.

Description

technical field [0001] The invention relates to a water sample sampling tool, in particular to a water sample sampler. Background technique [0002] Water body sampling is an important part of water environment scientific research and water environment protection and management. In shallow sea water sampling, the water inlet of existing equipment is not smooth. In harsh sea conditions, sampling must be completed as soon as possible. After a while, the collected water samples are not in-situ water samples, and the water depth of the water collector can only be determined by visual inspection or operating experience. When the water flow is large, the collected water samples may not be in-situ real samples. For water samples, the error is large, and the volume of the existing water collector is increased. More water samples are collected than required, and the impurities in the water will precipitate rapidly in the sampler, causing the supernatant to be mixed down, thereby aff...
