Description

A water quality sampler

technical field

The utility model relates to the field of water quality detection equipment, in particular to a water quality sampler.

Background technique

A water quality sampler is a device for collecting water quality samples. In order to protect the purity of water, water samples are regularly extracted at time intervals to prevent urban sewage and factory wastewater from being discharged into rivers and pollute water sources. The existing water quality sampling devices are divided into automatic and There are two kinds of manual sampling tools. Manual sampling tools include buckets, single-layer water sampling bottles, upright water dispensers, etc. Generally, sampling bottles with handles are used, but this method is easy to cause when the sampling position is higher than the water surface, such as: bridges, sewage It is often difficult to extend the sampling bottle to the water surface on the side of the ditch or on the deck with a high position, or when it is necessary to collect deep water samples, the position of the sampling bottle cannot reach the depth, which affects the representativeness of the sampling, resulting in unrepresentative monitoring results , and most of the sampling devices have only one sampling container, and it is not possible to take water samples from different locations at the same time. The samples in the sampling bottle need to be poured out and washed before sampling. The operation is cumbersome, time-consuming and laborious.

Utility model content

The purpose of this utility model is to provide a water quality sampler, which has simple structure, reasonable design, accurate sampling, time-saving and labor-saving, safe and efficient sampling, and can float on the water surface, automatically fetch water in different periods according to needs, and obtain water samples. In different sampling bottles, the problem of relying on people for sampling and monitoring for many years has been solved.

In order to achieve the above purpose, the utility model provides the following technical solutions: a water quality sampler, including a water pump, a water sample tube A, a water sample tube B and a sampling bottle, the lower end of the water pump is connected with a vertical pipe, the water pump The lower end is detachably connected with a vertical pipe, the vertical pipe is hollow, and a water sample tube A is arranged in the vertical pipe, and the lower end of the water sample tube A passes through the lower end of the vertical pipe to communicate with the sampling head, and the sampling head Connected to the lower end of the vertical pipe, the upper end of the water sample pipe A communicates with the water sample pipe B through a pump, and the lower part of the water sample pipe B is connected with three connecting pipes, and the three connecting pipes are connected to the sampling bottle in the vertical pipe , the sampling bottle is provided with a scale line, and the sampling bottle is detachably connected to three connecting pipes.

Preferably, the outer wall of the standpipe is wrapped with sponge.

Preferably, a string is fixedly connected to the outer wall of the standpipe.

Preferably, the sampling bottle is made of stainless steel.

Preferably, valves are provided on the three connecting pipes.

Compared with the prior art, the beneficial effects of the utility model are as follows:

The utility model is simple in structure, reasonable in design, accurate in sampling, time-saving and labor-saving, safe and efficient in sampling, and can float on the water surface, and automatically fetch water in different periods according to needs, and the obtained water samples are packed in different sampling bottles, which solves the problem for many years. Come to rely on people to squat to monitor the problem of sampling.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, the utility model provides a technical solution: a water quality sampler, comprising a water pump 1, a water sample tube A2, a water sample tube B3 and a sampling bottle 4, the lower end of the water pump 1 is detachably connected with a vertical Pipe 5, the vertical pipe 5 is a hollow structure, the vertical pipe 5 is provided with a water sample pipe A2, the lower end of the water sample pipe A2 passes through the lower end of the vertical pipe 5 and communicates with the sampling head 6, and the sampling head 6 is connected to the lower end of the vertical pipe 5, the upper end of the water sample pipe A2 communicates with the water sample pipe B3 through the pump 1, and the lower part of the water sample pipe B3 is connected with three connecting pipes 7, and the three connecting pipes 7 are connected to the vertical pipe. The sampling bottle 4 in the tube 5 is connected, and the sampling bottle 4 is provided with a scale line, and the sampling bottle 4 is detachably connected to the three connecting pipes 7 .

The outer wall of the vertical pipe 5 is wrapped with a sponge 8, so that the device can float on the water surface, and the sampling head 6 at the lower end of the device is stretched into the water. The outer wall of the standpipe 5 is fixedly connected with a string 9, and the device is fixed by the string 9 to prevent the device from floating away, causing unnecessary trouble, and simultaneously not limiting the sampling point. The sampling bottle 4 is made of stainless steel to increase the structural strength of the device. The three connecting pipes 7 are all provided with valves 10, and by ingeniously cooperating with the valves 10 on the three connecting pipes 7, water can be taken in different time periods and locations without causing mixed pollution. The samples are divided into different sampling bottles 4 .
