[0002] Urban water supply quality monitoring refers to the regular, comprehensive and systematic monitoring and analysis of water sources, water quality and water quantity in urban water supply systems to ensure the safety of urban water supply quality. Among them, it is of great significance to test the water quality of urban water supply systems. The water quality of water sources should be tested according to national standards for total phosphorus, total nitrogen, COD, BOD, pH value and temperature in water. When sampling water sources, samples need to be taken at different locations of the water source. Before the second sampling, the existing sampling equipment needs to be cleaned to avoid the residual first sampling samples from mixing with the second sampling samples, which affects the detection accuracy. Therefore, when sampling water from the water source multiple times, the sampling process is complicated and takes a lot of time. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The water source sampling device of the utility model that can perform multiple sampling can realize multiple sampling by setting multiple sampling tubes to meet the needs of water quality detection in tap water sources. When sampling, there is no need to carry multiple devices, which is convenient to carry. At the same time, it effectively avoids the situation in which the residual first-sampled samples of the existing sampling equipment during the second sampling easily contaminate the second-sampled samples and affect the detection accuracy.

[0017] 2. The water source sampling equipment of the utility model which can take samples multiple times is provided with an anti-accidental collision mechanism. When a sampling tube completes sampling, a positioning component is used to position the pull-out plate above the sampling tube to avoid accidental collision with the pull-out plate and squeezing out the collected samples, which is beneficial to the storage effect of the samples.

[0018] 3. The water source sampling equipment of the utility model which can take samples multiple times can realize the rapid installation and disassembly of the sampling tube and facilitate the removal of samples by setting the installation components, so as to facilitate the subsequent detection of water quality and cleaning of the sampling tube. At the same time, the setting of the installation components can drive the sampling tube to move. When the sampling tube drives the extraction tube to move out of the sampling tube, it is convenient to realize the sampling work. When the sampling tube drives the extraction tube to move into the sampling tube, it can play a protective effect on the extraction tube.

[0019] 4. The water source sampling equipment of the utility model can take samples multiple times. When sampling is needed, the sampling tube drives the extraction tube to move downward, and the extraction tube applies pressure to the opening so that the opening can rotate, thereby playing a avoidance role for the extraction tube. When the extraction tube retracts to the inner wall of the sampling tube after sampling, the second reset spring can drive the sealing plate to reset, thereby playing a role of sealing the opening and preventing external impurities from entering the interior of the sampling tube.

DETAILED DESCRIPTION

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0029] Embodiment 1, as Figure 1-Figure 7 As shown, a water source sampling device capable of multiple sampling includes a sampling tube 11, an extraction mechanism and an anti-accidental collision mechanism. It should be noted that a handle 12 is fixedly mounted on the surface of the sampling tube 11 to facilitate carrying the device;

[0030] The extraction mechanism includes a plurality of sampling tubes 14, a plurality of pulling components and a plurality of mounting components. The plurality of sampling tubes 14 are equidistantly arranged inside the sampling cylinder 11. Each mounting component is arranged between the sampling cylinder 11 and a sampling tube 14. Each pulling component is located inside a sampling tube 14. An extraction tube 16 is fixedly installed at the bottom end of each sampling tube 14.

[0031] The installation assembly can be used to install the sampling tube 14, and multiple sampling tubes 14 are sequentially installed inside the sampling tube 11. The pull-out assembly on each sampling tube 14 can be used to sample the water quality of the tap water source, so as to facilitate testing after collecting water samples;

[0032] The anti-mistaken collision mechanism includes a column 22, a plurality of sliders 21 and a plurality of positioning components. The column 22 is fixed at the middle of the top end of the sampling tube 11. Each slider 21 is rotatably arranged at one side of the top end of a pull-out component. Each positioning component is located between the column 22 and a slider 21.

[0033] When a sampling tube 14 completes sampling, the positioning assembly can be used to position the pull-out assembly above the sampling tube 14 to ensure that the pull-out assembly cannot move, thereby avoiding accidental contact with the pull-out plate 19 and squeezing out the collected sample, which is beneficial to the storage effect of the sample.

[0034] like Figure 1-Figure 7 As shown, each pulling assembly includes a piston 17, a pulling rod 18 and a pulling plate 19, the piston 17 is slidably arranged inside the sampling tube 14, the pulling rod 18 is inserted into the top of the sampling tube 14, one end of the pulling rod 18 is fixedly connected to the piston 17, and the other end of the pulling rod 18 is fixedly connected to the pulling plate 19;

[0035] When sampling is needed, first use the installation assembly to move the sampling tube 14 so that the sampling tube 14 can drive the extraction tube 16 to move out of the sampling tube 11, and then push the pull-out plate 19 to the bottom. At this time, the piston 17 moves to the bottom of the sampling tube 14 to discharge the gas inside the sampling tube 14. Then, insert the bottom end of the extraction tube 16 into the water source, pull the pull-out plate 19, and the pull-out plate 19 drives the piston 17 to move upward through the pull rod 18 to extract the water quality, thereby realizing the sampling of the tap water source;

[0036] It should be noted that after the sampling is completed, the installation assembly is used again to drive the sampling tube 14 to move upward so that the extraction tube 16 can be moved into the interior of the sampling cylinder 11 .

[0037] like Figure 1-Figure 7 As shown, the outer side of the pull-out plate 19 is rotatably connected to a rotating sleeve 20 via a bearing, and a slider 21 is fixedly mounted on one side of the rotating sleeve 20;

[0038] The sliding block 21 can be rotated by utilizing the rotation connection between the rotating sleeve 20 and the drawer plate 19 .

[0039] like Figure 1-Figure 7 As shown, each positioning assembly includes a slide groove 23, two positioning rods 24, two positioning holes 25, two pull plates 26 and two first return springs 27. The slide groove 23 is opened on the surface of the column 22, and the slider 21 is slidably arranged inside the slide groove 23. The two positioning holes 25 are symmetrically opened on both sides of the slider 21.

[0040] Two positioning rods 24 are located at both sides of the top of the slide slot 23 and are symmetrically slidably arranged on the column 22. A pull plate 26 is fixed to one end of each positioning rod 24 away from the slide slot 23. The other end of each positioning rod 24 is plugged into the positioning hole 25. Each first return spring 27 is sleeved on a positioning rod 24. Both ends of each first return spring 27 are respectively in contact with the column 22 and a pull plate 26.

[0041] When the sampling tube 14 moves up and down, it can drive the slider 21 to slide inside the slide groove 23;

[0042] When a sampling tube 14 completes sampling and the sampling tube 14 is reset under the action of the installation assembly, the sampling tube 14 can drive the slider 21 to move inside the slide groove 23. When the slider 21 moves to the bottom of the positioning rod 24, the pull plates 26 on both sides are pulled. The pull plates 26 can drive the positioning rod 24 to move, which plays a role of avoiding the slider 21. At the same time, the first reset spring 27 is deformed.

[0043] When the positioning holes 25 on both sides of the slider 21 move to the positioning rod 24, the pull plate 26 is released, and the pull plate 26 is reset under the action of the first reset spring 27, which can then drive the positioning rod 24 to reset, so that the positioning rod 24 can be inserted into the interior of the positioning hole 25, thereby achieving the positioning of the pull-out plate 19, avoiding accidental contact and squeezing of the pull-out plate 19, and squeezing out the sample inside the sampling tube 14.

[0044] like Figure 1-Figure 7 As shown, the mounting assembly includes a mounting hole 13 and a threaded sleeve 15. The mounting hole 13 is opened inside the sampling tube 11. The threaded sleeve 15 is fixedly sleeved on the outer surface of the sampling tube 14. The mounting hole 13 and the threaded sleeve 15 are threadedly matched.

[0045] Insert the sampling tube 14 into the mounting hole 13, and rotate the sampling tube 14. Due to the threaded fit between the mounting hole 13 and the threaded sleeve 15, the sampling tube 14 can be installed in the mounting hole 13. In the initial state, the extraction tube 16 is located in the sampling cylinder 11. When sampling is required, the sampling tube 14 is continuously rotated, and the sampling tube 14 can drive the extraction tube 16 to move downward, so that the extraction tube 16 can be moved out of the sampling cylinder 11. When the sampling tube 14 needs to be reset, the sampling tube 14 is rotated in the opposite direction, and the extraction tube 16 can be driven to move upward into the sampling cylinder 11.

[0046] It should be noted here that when resetting the sampling tube 14 after sampling is completed, it is necessary to manually pull the pull-out plate 19 upward to ensure that the pull-out plate 19 and the sampling tube 14 move upward synchronously.

[0047] like Figure 4 and Figure 7 As shown, a bottom plate 34 is fixed to the bottom end of the sampling tube 11, and a plurality of openings 28 are provided on the surface of the bottom plate 34 and penetrate the bottom plate 34. Each opening 28 is located below a pull plate 26, and the inner diameter of each opening 28 is larger than the outer diameter of an extraction tube 16. The setting of the opening 28 facilitates the passage of the extraction tube 16 to facilitate sampling.

[0048] like Figure 1-Figure 7 As shown, a blocking plate 29 is provided at the bottom end of the bottom plate 34 and on one side of the opening 28. Two mounting seats 30 are fixed to the bottom surface of the bottom plate 34 on one side of the blocking plate 29. A rotating shaft 32 is fixed in the middle of the two mounting seats 30. Two mounting plates 31 are fixed to one end of the blocking plate 29 away from the bottom plate 34. The other end of each mounting plate 31 is rotatably set on the rotating shaft 32. Two second return springs 33 are sleeved on the rotating shaft 32. The two ends of the second return spring 33 are respectively in contact with the blocking plate 29 and the bottom plate 34.

[0049] When sampling is required, the sampling tube 14 drives the extraction tube 16 to move downward, and the extraction tube 16 applies pressure to the opening 28 so that the opening 28 can rotate, thereby playing a evasive role for the extraction tube 16. When the extraction tube 16 retracts to the inner wall of the sampling tube 11 after sampling, the second reset spring 33 can drive the sealing plate 29 to reset, thereby playing a blocking role on the opening 28 and preventing external impurities from entering the interior of the sampling tube 11.
