Description

Portable Shallow Water Quality Sampling Device

technical field

The utility model relates to the technical field of water quality monitoring, in particular to a portable shallow water quality sampling device.

Background technique

As the environmental pollution becomes more and more serious, people's awareness of environmental protection is gradually increasing, and they pay more and more attention to the monitoring of the environment, the most important task of which is the monitoring of water quality. Water quality sampling device is an important equipment in water quality monitoring.

The current sampling bottle adopts a single-mouth bottle, which is difficult to empty the air in the sampling bottle during the sampling process; and the water flow is blocked by the bottom of the single-mouth bottle, which destroys the flow field of the water flow, often resulting in unrepresentative monitoring results;

In some places, floating plants such as moss and dead branches cover the water surface, affecting water sampling. Therefore, be badly in need of a kind of easy-to-use water quality sampling device, be used for sampling the water of different depths, avoid the pollution of moss, dead branch etc. simultaneously.

For shallow waters with a depth of less than 5m, domestic and foreign samplers are mainly divided into automatic unmanned sampling equipment and manual sampling equipment. Fully automatic unmanned sampling equipment is expensive in construction and maintenance costs, while manual sampling equipment mostly uses single-mouth glass bottles, which cannot solve the technical difficulty of the sampler exhausting in water.

Contents of the invention

The purpose of the utility model is to provide a portable shallow water quality sampling device which is convenient to operate when water quality sampling is carried out in the field.

The purpose of this utility model is achieved through the following technical solutions:

The portable shallow water quality sampling device comprises a water gun, a piston assembly and a sampling bottle, the piston assembly is inserted inside the water gun, and the sampling bottle is arranged under the water gun.

The water gun is composed of a gun barrel and a conduit. The conduit is composed of a hose and a stainless steel pipe. The hose is sleeved on the stainless steel pipe. There is a branch pipe on the side wall, and the branch pipe and the gun barrel are of an integrated structure.

The piston assembly is composed of a handle, a push rod and a rubber plug, the handle and the rubber plug are respectively connected to two ends of the push rod, and the rubber plug is inserted into the gun barrel.

The mouth of the sampling bottle is provided with a bottle stopper, the sampling bottle is arranged under the branch pipe, and the inner wall of the sampling bottle is attached to the branch pipe.

The branch pipe is provided with a water stop clip.

The conduit is provided with a screw clamp.

The utility model has beneficial effects: the stainless steel tube of the utility model has a certain hardness, and will not be washed away from the vertical direction by the water flow for a large distance, and it is easy to control the depth of sampling, and the branch pipe of the water gun is convenient for injecting water into the sample after taking water Inside the bottle, the device has a simple structure, convenient operation, and good flexibility, and is suitable for water quality at different levels of shallow water, which is conducive to improving the comprehensiveness of water quality monitoring.

detailed description

In order to facilitate those of ordinary skill in the art to understand and implement the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1-5, the portable shallow water quality sampling device includes a water gun 1, a piston assembly 2 and a sampling bottle 3, the piston assembly 2 is inserted inside the water gun 1, and the sampling bottle 3 is arranged below the water gun 1.

The water gun 1 is composed of a gun barrel 11 and a conduit 13. The conduit 14 is composed of a hose 141 and a stainless steel pipe 142. The hose 141 is set on the stainless steel pipe 142. The front end of the gun barrel 11 is provided with a variable diameter joint 12. The hose 141 Connected on the reducing joint 12, the side wall of the front end of the gun barrel 11 has a branch pipe 13, and the branch pipe 13 and the gun barrel 11 have an integrated structure.

The piston assembly 2 is composed of a handle 21 , a push rod 22 and a rubber plug 23 , the handle 21 and the rubber plug 23 are respectively connected to two ends of the push rod 22 , and the rubber plug 23 is inserted into the gun barrel 11 .

The mouth of the sampling bottle 3 is provided with a bottle stopper 31 , the sampling bottle 3 is arranged below the branch pipe 13 , and the inner wall of the sampling bottle 3 is attached to the branch pipe 13 .

The branch pipe 13 is provided with a water stop clip 131 .

The conduit 14 is provided with a screw clamp 143 .

Embodiment: When taking water, first close the water stop clip 131, insert the stainless steel pipe 142 end of the conduit 14 into the appropriate depth of the sampling water body, pull the handle 21 slowly and evenly, so that the piston assembly 2 is separated from the front end of the gun barrel 11, and the water sample is injected ; After the water sample is filled with the gun barrel 11 of the water gun 1, close the screw clamp 143, then fasten the sampling bottle 3 on the branch pipe 13, open the water stop clamp 131, and push the handle 21 forward evenly to make the gun barrel 11 Inject the water sample in the sampling bottle 3, until the sampling bottle 3 is completely filled and there is water overflow, make the sampling bottle 3 separate from the branch pipe 13, and cover the bottle stopper 31, because the bottle stopper 31 will occupy a certain space of the sampling bottle 3 , when the bottle stopper 31 is covered, a certain volume of water sample will be removed outwards, so that no air bubbles will be produced in the sampling bottle 3, and no air will stay.
