Description

TECHNICAL FIELD

[0001] The utility model relates to water quality analysis detection appliance field, in particular to a container structure for water quality analysis and detection. BACKGROUND

[0002] In the water quality analysis and detection process, the container is an important tool for collecting, storing and transporting water samples. In the existing various technical means, the most common way of water taking operation is completed by the operator with the help of a glass bottle or a plastic bottle.

[0003] Specifically, in the actual water taking operation, the operator needs to hold the container and carefully immerse it into the specific water body. As the container gradually penetrates into the water body, the air inside the container will gradually be discharged due to the influence of water pressure and water level rise. At the same time, the surrounding water will gradually penetrate into the container under the action of pressure difference and gravity.

[0004] However, during the immersion of the container, the trailing vortex generated by the rising of the air bubbles in the container will disturb the surrounding water, causing vertical mixing. For example, water bodies at different depths and positions may have different water quality characteristics, but due to disturbance, the water bodies in these areas may mix with each other, resulting in the final collected water sample not being able to truly reflect the actual situation of the original water body, thereby reducing the reliability and scientificity of the sampling result.

[0005] In addition, during the water taking process, the outer surface of the container will be in direct contact with the water body. The water body usually contains various substances, including corrosive substances or impurities that are easy to adhere to the surface of the object. These substances will gradually adhere to the outer surface of the container during the contact process, not only making the appearance of the container rough and dirty, but also eroding the material of the container, shortening its service life, increasing the use cost and replacement frequency.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0038] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, obvious and easy to understand, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0039] With reference to Figures 1-3 The utility model provides a kind of container structure for water quality analysis and detection, including sampling bottle body 1 and sampling bottle cap 7, and sampling bottle body 1 is detachably connected with sampling bottle cap 7 by thread.Sampling bottle body 1 is made of transparent material, it is convenient to observe the volume of sampling water body, and its lateral wall upper end is oppositely provided with water inlet pipe 2 and vacuum pipe 3.Water inlet pipe 2 is communicated with the water body to be measured by first connecting pipe 4, and vacuum pipe 3 is connected with vacuum equipment by second connecting pipe 5.In first connecting pipe 4 and second connecting pipe 5, stop water clamp (not shown in the drawing) is detachably connected, for controlling the on-off of water flow and vacuum state.

[0040] In use, first install the sampling bottle cap 7 on the sampling bottle body 1, then remove the water stop clamp on the first connecting pipe 4 and the second connecting pipe 5, connect the other end of the first connecting pipe 4 to the water body to be measured, and connect the other end of the second connecting pipe 5 to a vacuum device (such as a vacuum pump). After starting the vacuum device, a negative pressure is formed in the sampling bottle body 1, and the water body to be measured is pressed into the bottle body from the first connecting pipe 4 by atmospheric pressure. After sampling is completed, the other end of the first connecting pipe 4 is removed from the water body to be measured, the connection between the second connecting pipe 5 and the vacuum device is disconnected, and the water stop clamp is reinstalled on the first connecting pipe 4 and the second connecting pipe 5, thus completing the sampling process of the water body to be measured.

[0041] The side wall of the sampling bottle body 1 is marked with a first scale line 6 for accurately measuring the volume of the water sample. The water inlet pipe 2 and the vacuum pipe 3 are located above the first scale line 6, and the volume of the water body to be measured should be lower than the first scale line 6. This design can prevent the water sample to be measured from entering the vacuum device through the vacuum pipe 3, and also prevent the water body to be measured from flowing out through the first connecting pipe 4 and the second connecting pipe 5 after collection is completed.

[0042] The sampling bottle cap 7 is detachably connected to the sampling bottle body 1, which is convenient for installation and disassembly. After sampling is completed, the sampling bottle cap 7 can be removed from the sampling bottle body 1, and the water sample to be measured can be taken out by pouring. Due to the wide distribution of sampling sites, the preservation and transportation time of the original water sample collected in remote areas is relatively long. According to the requirements of routine laboratory analysis, it is necessary to add dilute sulfuric acid, dilute hydrochloric acid, sodium hydroxide and other solutions as protective agents in such original water samples. The inside of the sampling bottle cap 7 is provided with a dosing mechanism for adding protective agents to the sampling bottle body 1.

The dosing cylinder 8 contains protective agents and is provided with a dosing port 10 at the bottom end. The piston 11 is slidingly connected in the dosing cylinder 8 to control the injection of protective agents. The force applying rod is movably inserted through the top plate of the sampling bottle cap 7, and the lower end thereof is connected to the piston 11.

[0044] The medicine adding opening 10 is in an up-down horn structure, and the small opening is integrally formed with the medicine adding cylinder 8.

The plugging assembly is arranged to avoid the sampling bottle body 1 from shaking and affecting sampling. Specifically, the plugging assembly comprises a support plate 12, a plugging ball 14 and an elastic plate. The support plate 12 is fixedly connected with the small opening of the medicine adding opening 10, and a plurality of through holes 13 are arranged on the support plate 12 to allow the protective agent to pass through. The plugging ball 14 is movably connected with the large opening of the medicine adding opening 10, and can plug the medicine adding opening 10 as required. The elastic member 15 is connected with the support plate 12 and the plugging ball 14 at two ends, and functions to drive the plugging ball 14 to move upward, thereby realizing the plugging of the medicine adding opening 10. In an embodiment of the present application, the elastic member 15 is a tension spring, and the plugging ball 14 and the elastic member 15 are both metal materials, such as iron, and the outer surfaces thereof are subjected to plastic coating treatment, for example, epoxy resin coating, to have good chemical corrosion resistance.

[0045] With reference to Figures 4-5 The utility model also configures a reagent bottle 16, the reagent bottle 16 is the cylinder structure of upper end opening, and the inside is equipped with protective agent. The magnet 17 is embedded in the center of the bottle bottom of reagent bottle 16. The magnet 17 can selectively be attracted to the plugging ball 14, overcome the elastic force of elastic member 15 and make the plugging ball 14 move downward, and then remove the plugging of medicine adding opening 10, by driving the piston 11 to slide upward, the protective agent can be injected into the sampling bottle body 1.

[0046] The force applying rod member comprises a fixed sleeve 18 and a force applying rod 19. The lower end of the fixed sleeve 18 is fixedly connected with the piston 11. The lower end of the force applying rod 19 is slidingly connected with the upper end of the fixed sleeve 18, and the upper end is movably penetrated through the top plate of the sampling bottle cap 7. The side wall of the fixed sleeve 18 is provided with an inverted "L" shaped sliding groove 20, and the lower end of the side wall of the force applying rod 19 is provided with a sliding protrusion 21. The sliding protrusion 21 is slidingly connected with the sliding groove 20, so as to realize the up-down movement of the piston 11. The upper end of the force applying rod 19 is penetrated through the top plate of the sampling bottle cap 7, and is fixedly connected with a magnetic ball 22. The circumferential side of the force applying rod 19 is sleeved with a metal ring 23, the metal ring 23 is fixedly connected with the top plate of the sampling bottle cap 7, and is detachably connected with the magnetic ball 22, so as to facilitate operation and replacement.

[0047] The process of adding the protective agent into the sampling bottle body 1 through the medicine adding barrel 8 is as follows: the magnetic ball 22 is pulled upward to be disconnected with the metal ring 23, then the magnetic ball 22 is pulled upward and rotated to make the sliding protrusion 21 slide into the horizontal slot of the sliding slot 20, then the force applying rod 19 is applied downward to drive the piston 11 to move downward relative to the medicine adding barrel 8, the protective agent extrudes the blocking ball 14 to move downward to unblock the medicine adding opening 10, so that the protective agent is added into the sampling bottle body 1. After the adding is completed, the blocking ball 14 is reset under the action of the elastic member 15 to block the medicine adding opening 10 again, the force applying rod 19 is screwed to make the sliding protrusion 21 slide into the vertical slot of the sliding slot 20, and finally the magnetic ball 22 is reconnected with the metal ring 23.

[0048] The process of adding the protective agent into the medicine adding barrel 8 through the reagent bottle 16 is as follows: the protective agent is contained in the reagent bottle 16, the medicine adding opening 10 below the medicine adding barrel 8 is abutted above the bottom of the reagent bottle 16 and is staggered with the magnet 17, then the blocking ball 14 is moved close to the magnet 17 through horizontal sliding, the mutual attraction between the magnet 17 and the blocking ball 14 can overcome the elastic force of the elastic member 15 on the blocking ball 14, so that the blocking ball 14 moves downward relative to the medicine adding opening 10 to unblock the medicine adding opening 10. The magnetic ball 22 is pulled upward to be disconnected with the metal ring 23 until the fixed sleeve 18 and the piston 11 are driven to slide upward, at this time, the protective agent in the reagent bottle 16 gradually enters the fixed sleeve 18. After the adding is completed, the blocking ball 14 is moved away from the magnet 17 through horizontal translation, and meanwhile, the blocking ball 14 is ensured not to be separated from the medicine adding opening 10, along with the gradually reduced attraction between the blocking ball 14 and the magnet 17, the blocking ball 14 blocks the medicine adding opening 10 again under the action of the elastic force of the elastic member 15, then the magnetic ball 22 is reconnected with the metal ring 23 to reset.

[0049] The sampling bottle cap 7, the medicine adding barrel 8 and the reagent bottle 16 are all made of transparent material, so that the adding amount of the protective agent and the state of the water sample can be observed.
