Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial water use, in particular to a separable sampling device for water quality detection of water supply and use pipelines. Background Technique
[0002] The water used in industrial pipelines may be affected by various factors such as raw materials, production processes, and equipment conditions, resulting in water quality changes. Regular sampling and detection are important links to ensure that the water quality meets the requirements of front-end production and back-end wastewater discharge. At present, the sampling of industrial pipeline water is mainly fixed-position sampling.
[0003] The fixed-position sampling of pipelines is generally divided into single-point sampling and multi-point sampling. Among them, single-point sampling means that only one fixed point is set in the pipe network to install a sampling valve or a sampling pump. When sampling, the valve or the sampling pump is opened, and the water is taken with a sterile sampling bottle with disinfection measures. Finally, the sampling bottle is sealed and labeled to complete the sampling; multi-point sampling is to set multiple fixed sampling points on the basis of single-point sampling, which enhances the rationality and representativeness of sampling to a certain extent.
[0004] Whether it is a single-point or multi-point sampling device, during the sampling process, the water inlet of the sampling valve or the water inlet of the sampling pump and the sampling bottle are not in a closed area, and the outside air will have a certain impact on the water quality of the pipeline sampling. After sampling is completed, it is necessary to disconnect the connection between the water inlet of the valve or the water inlet of the sampling pump and the sampling bottle, and then complete the sealing of the bottle mouth. During this process, the sampling bottle will be in contact with the air for a period of time, which will further affect the sampling water quality. Content of the Utility Model
[0005] The purpose of the utility model is to provide a separable sampling device for water quality detection of water supply and use pipelines, which can keep the sampling steps in a closed environment and avoid the influence of the sample's contact with air on the water quality.

[0029] Embodiment
[0030] A hole for installing a sampling device is preset on the pipe wall of the water conveyance pipeline. As Figures 1 to 5 shown, a separable sampling device for water quality detection of water supply and use pipelines includes: a water inlet assembly 1, a water collection assembly 2, and a floating structure 3. As Figure 1 , Figure 3 and Figure 4 shown, the water inlet assembly 1 includes: a curved water inlet structure 11, a connecting pipe 12, and a communicating pipe 13. As Figure 1 shown, the curved water inlet structure 11 is an arc-shaped plate body, and the radian fits the radian of the inner wall of the pipeline; one end of the connecting pipe 12 is connected to the pipe wall of the curved water inlet structure 11; the communicating pipe 13 is sleeved inside the connecting pipe 12, and one end is communicated with the bottom of the curved water inlet structure 11, which is called the water inlet, and there is a gap between the outer wall of the communicating pipe 13 and the inner wall of the connecting pipe 12, and the top of this gap is the bottom surface of the curved water inlet structure 11. The communicating pipe 13 is configured with an opening and closing device 14, and the opening and closing device 14 is used to control the opening and closing of the water inlet of the communicating pipe 13. The bottom of the curved water inlet structure 11 is attached to the inner wall of the pipeline, and the connecting pipe and the communicating pipe pass through the preset hole, and the gap between the hole and the outer wall of the connecting pipe is sealed; As Figure 2 shown, the water collection assembly 2 includes: a water collection bottle 21 and a magnetic ring 22. As Figure 1 shown, the bottle mouth of the water collection bottle 21 is connected to the connecting pipe 12, and the bottle mouth is aligned with the communicating pipe 13. The water body enters the interior of the water collection bottle 21 through the communicating pipe 13 and then through the bottle mouth; the magnetic ring 22 is embedded in the inner wall of the bottle mouth. The magnetic ring 22 can be a magnetic ring or can be designed as an annular ring structure with a magnet at the bottom; As Figure 5As shown in the figure, the floating body structure 3 includes: a floating body frame 31, a floating body 33, and a magnetic plate 34. The top of the floating body frame 31 is connected to the bottom of the magnetic ring 22. A connecting rod 32 capable of sliding along the height direction of the water collecting bottle 21 is provided on the floating body frame 31; the floating body 33 is located inside the bottle body of the water collecting bottle 21, and the floating body 33 is connected to the bottom of the connecting rod 32. After water starts to enter the water collecting bottle 21, the floating body 33 can rise and fall according to the water level in the water collecting bottle 21. When the floating body 33 rises and falls, the connecting rod 32 slides upward; the magnetic plate 34 is connected to the top of the connecting rod 32. When the connecting rod 32 slides upward, the magnetic plate 34 continuously approaches the magnetic ring 22, and the water level continuously rises until the magnetic plate 34 is attracted to the magnetic ring 22. At this time, the mouth of the magnetic ring 22 is sealed by the magnetic plate 34, and at this time, water cannot enter the water collecting bottle 21, completing the quantitative sampling of water.
[0031] As Figure 1 shown, inclined cut surfaces are symmetrically arranged at both ends of the curved surface water inlet structure 11. The top of the cut surface inclines towards the middle of the curved surface water inlet structure 11, and the shape of the cut surface is a semi-elliptical shape. Through this structure, the resistance of the curved surface water inlet structure 11 to the water in the pipeline is reduced. At the same time, the pipe orifice of the connecting pipe 13 is flush with the inner wall of the curved surface water inlet structure to prevent the pipe orifice of the connecting pipe 13 from protruding from the inner wall of the curved surface water inlet structure and generating resistance to the flowing water in the water delivery pipe.
[0032] As Figure 2 、 Figure 4 、 Figure 6 and Figure 7 shown, the connecting pipe 13 is a threaded pipe with internal threads. A thread matching the connecting pipe 13 is provided on the side surface of the bottle mouth of the water collecting bottle 21. The bottle mouth of the water collecting bottle 21 and the connecting pipe 13 are connected by threads. Through this threaded connection method, it is more convenient for users to quickly disassemble and install the water collecting bottle 21 and the curved surface water inlet structure 11.
[0033] As Figure 2 and Figure 7 shown, in order to ensure that all the water in the pipeline enters the water collecting bottle 21 through the connecting pipe 13 at the bottom of the curved surface water inlet structure 11, a sealing ring 23 is provided on the top end surface of the bottle mouth, thereby ensuring the sealing performance at the connection between the bottle mouth and the connecting pipe 13.
[0034] As Figure 4As shown, the opening and closing device 14 is a handwheel valve. After enough water samples are collected in the water collection bottle 21, the magnetic plate 34 seals the opening of the magnetic ring 22 so that water no longer enters the water collection bottle 21. That is, after sampling is completed, the water collection bottle 21 needs to be detached from the connecting pipe 12. At this time, turn the handwheel of the valve to close the valve port, thereby closing the water inlet of the connecting pipe 13. At this time, when the water collection bottle 21 is removed, water will not flow out of the connecting pipe 13. It should be noted that the connecting pipe 12 in this embodiment is an internal threaded pipe. During use, turning the water collection bottle can complete the threaded connection with it. The rotating rod of the handwheel penetrates outside the connecting pipe 12 to facilitate the user to operate the handwheel and thus control the opening and closing of the valve port.
[0035] In some embodiments, the magnetic plate 34 is a circular plate structure, which matches the structures of the bottle mouth and the magnetic ring.
[0036] In some embodiments, the bottom of the curved water inlet structure 11 is adhered to the inner wall of the pipe through adhesive rubber, thereby further fixing the curved water inlet structure 11 and the inner wall of the pipe.
[0037] As Figure 5 shown, the floating body frame 31 includes: a first ring, a second ring, a sleeve and two vertical rods. The first ring is connected to the bottom of the magnetic ring 22. The first ring can be designed as a metal structure and magnetically connected to the magnetic ring 22; the second ring has the same radius as the first ring and is located directly below the first ring vertically; the sleeve is fixed at the center of the second ring through an auxiliary rod, and the connecting rod 32 is slidably sleeved in the sleeve. The sliding track of the connecting rod 32 is limited by the vertically arranged sleeve so that the connecting rod 32 can only slide along the height direction of the water collection bottle 21; the two vertical rods are connected between the first ring and the second ring and are symmetrically arranged. The two ends of the magnetic plate 34 slide on the vertical rods respectively, so that the sliding of the magnetic plate 34 is more stable.
[0038] The specific operation of this embodiment is as follows:
[0039] During the water collection in the pipeline, with the water inlet of the curved water inlet structure 11 in the open state, water flows into the water collection assembly 2 from the connecting pipe 13 by the action of gravity. As the water inflow increases, the water level in the water collection bottle 21 gradually rises. The floating body 33 drives the connecting rod 32 by the buoyancy force, causing the magnetic plate 34 to gradually move upward. After the water level reaches a certain height, the magnetic plate 34 is attracted to the magnetic ring 22 by the magnetic force, thereby achieving the purpose of closing the water collection device and realizing automatic quantitative water collection. After the water collection is completed, the water inlet is closed through the opening and closing device 14, so as to realize the fully enclosed sampling of pipeline water without affecting the normal water supply of the pipe network.
[0040] The water collection component 2 is installed at one or two positions in each link of the pipeline to achieve daily water quality sampling and monitoring of the pipeline; when water quality fluctuations or pollution are detected at the outlet end of the pipeline, the water collection component with existing water samples inside is replaced by a water collection component without water samples inside. The water collection component without water samples inside does not need to be replaced. The relevant staff opens the water inlet of the water inlet component, and after water collection, sampling and monitoring are carried out, so as to quickly locate the water quality pollution source and give timely feedback for treatment.
[0041] The above-disclosed are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
