Description

Technical Field

[0001] This invention belongs to the field of water quality testing technology, and in particular relates to a water quality testing device for industrial circulating water. Background Technology

[0002] Industrial circulating water is water used in industrial production to meet the process requirements of cooling, washing, etc., and can be reused after treatment. The core is to reduce the consumption of fresh water and wastewater discharge through circulation.

[0003] In order to solve the problems of scaling, corrosion and microbial contamination in the circulating water system, our company has independently developed an industrial circulating water treatment technology system, the Physical Treatment System (PTS), which uses purely physical means to replace traditional chemical agents for treatment.

[0004] In order to test whether the water quality of the industrial circulating water treated by the physical treatment system meets the standards, it is necessary to sample and test the treated industrial circulating water.

[0005] When it is necessary to test the water quality of the treated circulating water in the pool, the water quality in the pool is unevenly layered (more microorganisms on the surface, more sediment at the bottom) and varies regionally (the water quality at the inlet and outlet is different). Therefore, if the water quality is sampled in the unevenly layered state, the existing water quality testing sampler (such as a long-handled sampler) requires the operator to take the sampler out of the pool multiple times to sample the water quality of different water layers. Moreover, the sampler needs to be cleaned after each water quality sample is collected, which will affect the efficiency of water quality sampling and testing. At the same time, it is not possible to accurately insert the sampler into the designated position in the pool, which will affect the accuracy of the water quality test after the sample is collected. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a water quality testing device for industrial circulating water, comprising a protective cylinder placed inside a water tank, and a climbing frame erected on the water tank to support the protective cylinder. It also includes: a collection cylinder, several of which are placed inside the protective cylinder with their upper openings open; a sampling cylinder, movably placed inside the collection cylinder via a suspension frame; a supporting and conductive assembly, placed inside the collection cylinder, with its water collection groove communicating with a water collection hole on the protective cylinder; and a venting and exhausting assembly, placed inside the sampling cylinder, allowing the sampling cylinder to communicate with the water collection groove of the supporting and conductive assembly through the venting and exhausting assembly.

[0008] Among them, several water collection holes are arranged in a spiral on the protective cylinder, so that the water collection groove installed on each collection cylinder corresponds to the water collection hole at different heights.

[0009] Furthermore, the suspension frame includes a cross movably placed on the opening of the collection tube, a suspension rod installed on the cross, a support plate installed at the bottom of the suspension rod, a connecting rod installed on the support plate, a collar connected to the connecting rod, and a clamping plate installed on the inner ring surface of the collar for clamping the sampling tube, and several clamping plates are rotatably connected to adjusting screws threaded on the collar.

[0010] Furthermore, the support and conduction assembly includes a support plate installed inside the collection cylinder for supporting the sampling cylinder, a conduction pipe installed at the center of the support plate, and a flow pipe communicating with the side wall of the conduction pipe and the water collection groove;

[0011] The water collection groove has its opening facing the outside of the protective cylinder, and its bottom is closed. A sealing plate for sealing the opening of the guide pipe is installed at the bottom of the groove.

[0012] The collecting cylinder is equipped with a pushing support mechanism for driving the sealing insert plate to move, so that the opening of the guide pipe connected to the water collecting groove is in an open or blocked state.

[0013] Furthermore, the pushing support mechanism includes an ear block installed on the outer wall of the collecting cylinder, a power unit installed on the ear block for driving the sealing insert plate to slide, and a sliding plate connected to the output end of the power unit;

[0014] The collecting cylinder has a sliding guide groove on its wall for the sliding plate to slide through, so that the sliding plate passes through the sliding guide groove and connects with the sealing insert plate. The bottom of the collecting cylinder is equipped with a spring for supporting and resetting the sliding plate.

[0015] Furthermore, the pushing support mechanism also includes a support column mounted on the sliding plate and an internal threaded sleeve mounted on the support column and connected to the ventilation and exhaust assembly, so that when the opening of the guide pipe is in an open or blocked state, the ventilation and exhaust assembly simultaneously connects or blocks the sampling cylinder with the other opening of the guide pipe.

[0016] Furthermore, the ventilation and exhaust assembly includes a sealing plug installed at the opening of the sampling cylinder, a guide sleeve placed at the center of the sealing plug and sealed and inserted into the ventilation tube, a movable guide tube movably placed inside the guide sleeve, a limiting ring installed on the movable guide tube and located outside the sampling cylinder, and a spring connected between the limiting ring and the guide sleeve.

[0017] The guide sleeve has a guide hole corresponding to the other opening of the guide tube, the movable guide tube has a strip hole on the same side as the guide hole, and the movable guide tube has a drain hole on the tube wall inside the sampling cylinder.

[0018] The bottom outer wall of the movable guide tube has a threaded groove that is threaded to the inner threaded sleeve, so that when the sliding plate moves up and down in the collecting cylinder, it drives the movable guide tube to move up and down in the guide sleeve.

[0019] Furthermore, the ventilation and exhaust assembly also includes a connecting conduit installed at the top of the movable conduit, a sealing guide sleeve installed at the top of the collecting cylinder and in contact with the outer wall of the connecting conduit, and a key block installed on the outer wall of the connecting conduit to restrict the rotation of the connecting conduit.

[0020] The connecting conduit has an open opening at its port outside the collecting cylinder, and several drainage holes are provided on its wall. The key block and the keyway vertically opened on the sealing guide sleeve cooperate with each other.

[0021] Furthermore, the cross is embedded in the notch groove opened at the top of the collection tube, and the top of the suspension rod is movably installed in the center hole of the cross through the cooperation of the threaded rod and the nut, and the top of the threaded rod has a polygonal hole.

[0022] The present invention has the following beneficial effects:

[0023] 1. This solution cleverly installs several equidistant and spirally rising water collection grooves inside the protective cylinder. Each water collection groove can be connected to the installed sampling cylinder through the support and conduction components and the conduction and exhaust components. Multiple sampling cylinders can simultaneously collect and sample water from different water layers in the pool. The water in the pool enters the sampling cylinder by gravity flow, so there is no need to provide suction force to the sampling cylinder. This allows for multi-layer sampling of the water in the pool, thereby enabling more accurate detection of the water quality indicators of industrial circulating water after physical treatment.

[0024] Since each sampling tube in this solution is connected to a water collection groove of independent height through an independent ventilation and exhaust assembly and a support ventilation assembly, it is also possible to collect and process surface water, middle water, or bottom water in the pool separately. This allows the water quality testing equipment in this solution to automatically sample and test water from different water layers in the pool, thereby enabling more accurate detection of the water quality of each layer in the pool.

[0025] 2. This solution cleverly incorporates a movable guide tube and a connecting tube that can be raised and lowered inside the sampling tube. When water is injected into the sampling tube through the movable guide tube, the connecting tube can act as a pressure relief pipe to expel excess gas from the sampling tube. This prevents the sampling tube from failing to collect a sufficient amount of water due to the inability of the gas pressure inside the sampling tube to be properly released when water is continuously injected, which would affect the accuracy of water quality testing in the pool.

[0026] When it is necessary to drain the water from the sampling tube through the connecting conduit, the movable conduit can act as an airflow conduit, allowing outside air to enter the sampling tube. This enables the water collected in the sampling tube to be discharged quickly and fully into multiple sampling bottles, allowing for accurate detection and processing of the collected water samples.

[0027] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0048] Please see Figures 1-9As shown, the present invention is a water quality testing device for industrial circulating water, including a protective cylinder 2 placed in a water tank, and a climbing frame 1 placed on the water tank to support the protective cylinder 2. It also includes four collection cylinders 3, arranged in a circumferential array and fixed inside the protective cylinder 2, with their upper openings open; a sampling cylinder 4, movably placed inside the collection cylinder 3 via a suspension frame 5; a supporting and connecting component 6, placed inside the collection cylinder 3, with its water collection groove 61 communicating with a water collection hole 21 on the protective cylinder 2; and a connecting and venting component 8, placed inside the sampling cylinder 4, allowing the sampling cylinder 4 to communicate with the water collection groove 61 of the supporting and connecting component 6 through the connecting and venting component 8. The four water collection holes 21 are arranged in a spiral equidistant pattern on the protective cylinder 2, such that the water collection groove 61 installed on each collection cylinder 3 corresponds to a water collection hole 21 at a different height.

[0049] It should be noted that: the climbing frame 1 is equipped with a ring frame for fixing the protective cylinder 2, and the ring frame is threaded with locking bolts for locking the protective cylinder 2, which makes it easy to remove the protective cylinder 2 from the climbing frame 1 after long-term use. The upper opening of the protective cylinder 2 is fastened with a cylinder cover by a locking fastener, and the cylinder cover is provided with a handle for opening the cylinder cover.

[0050] Assembly of Protective Cylinder 2: First, fix the sampling cylinder 4 to be sampled using the suspension frame 5. Then, insert the sampling cylinder 4 into the collection cylinder 3 in an inverted state. When the opening of the inverted sampling cylinder 4 touches the support and conduction component 6, the conduction and exhaust component 8 will connect with the support and conduction component 6 simultaneously, so that the four sampling cylinders 4 can be installed into the collection cylinder 3 in sequence. Then, install the protective cylinder 2 onto the ring frame of the climbing frame 1 fixed on the pool, so that the protective cylinder 2 is inserted into the pool and the bottom of the protective cylinder 2 is suspended in the pool (the bottom of the protective cylinder 2 is best 8-10 cm from the bottom of the pool), thus fixing the protective cylinder 2 into the pool.

[0051] Water sampling: When it is necessary to perform three-layer sampling of the water in the pool (the surface of the pool or near the inlet, the middle layer of the pool (0.5m from the water surface and 0.5m from the bottom of the pool), and the bottom layer of the pool or near the outlet), it is necessary to clean up the debris (such as floating algae and fallen leaves) around the protective cylinder 2. Then, the electrical appliances inside the protective cylinder 2 are powered on (power unit 72 on the support and conduction component 6), and then the power unit 72 installed on the three collection cylinders 3 is controlled to work, so that it opens the water collection grooves 61 on the three spirally and equally spaced water collection holes 21, so that the water in the surface, middle and bottom layers of the pool can pass through the water collection grooves 61. The support and conduction assembly 6 and the conduction and exhaust assembly 8 are simultaneously and automatically inserted into the three sampling cylinders 4 (since the sampling cylinders 4, which are inverted and inserted into the collection cylinder 3, are all located below the water surface in the pool, the water in the pool will be pressed into the sampling cylinders 4 through the open water collection groove 61 under external pressure). This allows the three sampling cylinders 4 to perform multi-layer automatic sampling of the water quality in the pool through the water collection holes 21 at different heights. Then, the power unit 72 of the support and conduction assembly 6 is controlled to close the water collection groove 61. At this time, the conduction and exhaust assembly 8 on the sampling cylinder 4 will also close simultaneously, so that the extracted water can be automatically stored in the sampling cylinder 4.

[0052] Water quality testing: After a certain amount of water from different depths is simultaneously extracted from three sampling cylinders 4, the testing personnel climb to the protective cylinder 2 using the climbing frame 1, open the cylinder cover, and then use the suspension frame 5 to remove the sampling cylinder 4 containing the extracted water from the corresponding collection cylinder 3. The extracted sampling cylinders 4 are then numbered according to the water layer corresponding to the extracted water. They are then refrigerated and stored as needed before being transported to the laboratory for water quality testing.

[0053] Preferably, if the inlet and outlet of the pool are on the same side, the climbing frame 1 can be assembled near the inlet and outlet of the pool, allowing the protective cylinder 2 to be installed at the inlet and outlet of the pool. This allows the water collection groove 61 near the upper water body to collect water near the inlet of the pool, reflecting the water quality before entering the pool. This allows for comparison and judgment of whether secondary pollution has occurred in the pool. The water collection groove 61 near the bottom of the pool can collect and test the water at the outlet of the pool / the suction port of the circulating pump. If the indicators here exceed the standard, it needs to be dealt with immediately to avoid equipment damage. If the inlet and outlet of the pool are not on the same side, the protective cylinder 2 can be installed near the center of the pool to achieve stratified sampling and testing of the flowing water in the pool.

[0054] This solution cleverly installs several equidistant and spirally rising water collection grooves 61 inside the protective cylinder 2. Each water collection groove 61 can be connected to the installed sampling cylinder 4 through the support and conduction component 6 and the conduction and exhaust component 8. Multiple sampling cylinders 4 can simultaneously collect and sample water from different water layers in the pool. The water in the pool enters the sampling cylinder 4 by gravity flow, so there is no need to provide suction force to the sampling cylinder 4 separately. This allows for multi-layer sampling of the water in the pool, thereby enabling more accurate detection of the water quality indicators of industrial circulating water after physical treatment.

[0055] Since each sampling cylinder 4 in this scheme is connected to the water collection groove 61 of an independent height through an independent ventilation and exhaust assembly 8 and a support ventilation assembly 6, it is also possible to collect and process the surface water, middle water, or bottom water in the pool separately. This allows the water quality testing equipment in this scheme to automatically sample and test the water in different water layers in the pool separately, thereby enabling more accurate detection of the water quality status of each water layer in the pool.

[0056] In a preferred embodiment of this solution, the suspension frame 5 includes a cross 51 movably placed on the opening of the collection tube 3, a suspension rod 52 mounted on the cross 51, a support plate 53 mounted on the bottom of the suspension rod 52, a connecting rod 54 mounted on the support plate 53, a collar 55 connected to the connecting rod 54, and a clamping plate 56 mounted on the inner surface of the collar 55 for clamping the sampling tube 4. At least four clamping plates 56 arranged in a circumferential array are rotatably connected to adjusting screws threaded on the collar 55.

[0057] It should be noted that, since the sampling tubes 4 inserted into the collection tube 3 at different heights, suspension rods 52 of different lengths need to be used in conjunction to ensure that the sampling tubes 4 inserted into the collection tube 3 can accurately contact and communicate with the support and conduction components 6 at different heights inside the collection tube 3.

[0058] When it is necessary to insert the sampling tube 4 upside down into the collection tube 3, the bottom of the sampling tube 4 should first be inserted into the collar 55. Then, turn the four adjusting screws to make the clamping plate 56 fit against the outer ring surface of the bottom of the sampling tube 4, so that the bottom of the sampling tube 4 is clamped onto the collar 55. Then, the clamped sampling tube 4 is inverted and placed into the collection tube 3. When the cross 51 contacts the upper opening of the collection tube 3, the sampling tube 4 reaches the appropriate position in the collection tube 3.

[0059] When a certain amount of water is collected in the sampling tube 4 and needs to be removed from the collection tube 3, the upper cover of the protective tube 2 should be opened first, and then the cross 51 should be held to pull the sampling tube 4 out of the collection tube 3, so that the sampling tube 4 containing water can be easily removed from the protective tube 2.

[0060] In a preferred embodiment of this solution, the supporting and guiding assembly 6 includes a support plate 62 installed inside the collection cylinder 3 for supporting the sampling cylinder 4, a guiding pipe 63 installed at the center of the support plate 62, and a guide pipe 64 communicating with the side wall of the guiding pipe 63 and the water collection groove 61; wherein, the opening of the water collection groove 61 faces the outside of the protective cylinder 2, and its bottom is in a closed state, and a sealing insert plate 65 for sealing the opening of the guide pipe 64 is installed at the bottom of the groove; wherein, the collection cylinder 3 is equipped with a pushing support mechanism 7 for driving the sealing insert plate 65 to move, so that the opening of the guide pipe 64 communicating with the water collection groove 61 is in an open or closed state;

[0061] It should be noted that the support plate 62 is fixed inside the collection cylinder 3 by welding or gluing. When the sampling cylinder 4 is inserted into the collection cylinder 3 upside down, the opening of the sampling cylinder 4 will touch the support plate 62, so that the support plate 62 can provide gravity support for the sampling cylinder 4. The ventilation and exhaust component 8 on the sampling cylinder 4 will be inserted into the ventilation pipe 63 and aligned with the opening of the guide pipe 64 connected to the ventilation pipe 63. When it is necessary to open the opening of the guide pipe 64 connected to the water collection groove 61, the pushing support mechanism 7 will drive the sealing plate 65 to descend on the bottom wall of the water collection groove 61, so that it opens the opening of the guide pipe 64, allowing the water in the pool to enter the sampling cylinder 4 through the water collection groove 61, the opened guide pipe 64 and the opened ventilation and exhaust component 8, so as to collect water samples.

[0062] When the pushing support mechanism 7 pushes the sealing insert 65 upward, the sealing insert 65 adheres to the bottom of the water collection groove 61, which will block the opening of the guide pipe 64. At the same time, the ventilation and exhaust assembly 8 will also be in a closed state, which facilitates the independent isolation of the water collected in the sampling tube 4 and the water outside the protective tube 2. This not only prevents the water collected by the sampling tube 4 from leaking, but also prevents the water in the pool from entering the collection tube 3 through the water collection groove 61, which could damage the components inside the collection tube 3.

[0063] In a preferred embodiment of this solution, the pushing support mechanism 7 includes an ear block 71 mounted on the outer wall of the collecting cylinder 3, a power unit 72 mounted on the ear block 71 for driving the sealing insert 65 to slide, and a sliding plate 73 connected to the output end of the power unit 72; wherein, the cylinder wall of the collecting cylinder 3 is provided with a moving guide groove 31 for the sliding plate 73 to slide, so that the sliding plate 73 passes through the moving guide groove 31 and connects with the sealing insert 65, and the bottom of the collecting cylinder 3 is provided with a spring member 84 for supporting and resetting the sliding plate 73;

[0064] It should be noted that the power unit 72 is preferably any of an electric push rod, a cylinder, or a hydraulic telescopic rod, or other power element capable of driving the sliding plate 73 to move up and down in the moving guide groove 31. Therefore, when the output rod of the power unit 72 extends, the sliding plate 73 will descend vertically in the moving guide groove 31. At this time, the spring 84 is in a continuously compressed state, causing it to drive the sealing insert 65 to descend vertically in the water collection groove 61, thereby opening the opening of the guide pipe 64. When the output rod of the power unit 72 retracts, the elastic restoring force of the spring 84 will also push the sliding plate 73 to rise vertically in the moving guide groove 31, causing it to drive the sealing insert 65 to slide upward and insert into the water collection groove 61, thereby sealing the opening of the guide pipe 64 connected in the water collection groove 61 (since the sealing insert 65 is slidably attached to the bottom surface of the water collection groove 61).

[0065] In a preferred embodiment of this scheme, the pushing support mechanism 7 further includes a support column 74 mounted on the sliding plate 73 and an internal threaded sleeve 75 mounted on the support column 74 and connected to the ventilation and exhaust assembly 8, so that when the opening of the guide pipe 64 is in an open or blocked state, the ventilation and exhaust assembly 8 simultaneously connects or blocks the sampling cylinder 4 with the other opening of the guide pipe 64.

[0066] The ventilation and exhaust assembly 8 includes a sealing plug 81 installed at the opening of the sampling cylinder 4, a guide sleeve 82 placed at the center of the sealing plug 81 and sealed and inserted into the ventilation tube 63, a movable conduit 83 movably placed in the guide sleeve 82, a limiting ring 85 installed on the movable conduit 83 and located outside the sampling cylinder 4, and a spring member 84 connected between the limiting ring 85 and the guide sleeve 82.

[0067] The guide sleeve 82 is provided with a guide hole 821 corresponding to the other opening of the guide tube 64, the movable guide tube 83 is provided with a strip hole 831 on the same side as the guide hole 821, and the movable guide tube 83 is provided with a drain hole 832 on the tube wall inside the sampling cylinder 4.

[0068] The bottom outer wall of the movable conduit 83 is provided with a threaded groove that is threaded to the inner threaded sleeve 75, so that when the sliding plate 73 moves up and down in the collecting cylinder 3, it drives the movable conduit 83 to move up and down in the guide sleeve 82.

[0069] It should be noted that the guide sleeve 82 extends into the sampling cylinder 4, which facilitates the sealing of the strip hole 831 opened on the movable guide tube 83 in the initial state. The diameter of the limiting ring 85 is smaller than the outer diameter of the guide sleeve 82, so that when the sampling cylinder 4 is inserted into the collection cylinder 3 inverted, the guide sleeve 82 can drive the movable guide tube 83 to accurately extend below the guide tube 63. The outer tube wall of the guide sleeve 82 inserted into the guide tube 63 is wrapped with a rubber layer, which can play a fitting and sealing role with the guide tube 63 without interfering with the normal rotation and descent of the guide sleeve 82.

[0070] Therefore, when the sampling tube 4 is inserted into the collection tube 3 upside down, the extended movable tube 83 will first pass down through the connecting tube 63, and then the guide sleeve 82 will be inserted into the connecting tube 63. When the bottom of the movable tube 83 is aligned with the inner threaded sleeve 75, the suspension rod 52 is rotated to make the sampling tube 4 rotate on the support plate 62. At this time, the sealing plug 81 will drive the guide sleeve 82 to rotate in the connecting tube 63, and the movable tube 83 will rotate and descend in the inner threaded sleeve 75 at the same time, thereby realizing the threaded connection between the bottom of the movable tube 83 and the inner threaded sleeve 75. After the movable tube 83 is connected to the inner threaded sleeve 75, the guide hole 821 opened on the guide sleeve 82 will be aligned with the opening of the guide tube 64 that is connected to the outer wall of the connecting tube 63.

[0071] When the power unit 72 drives the sliding plate 73 to descend vertically within the moving guide groove 31, the sealing insert 65 will descend within the water collection groove 61. Simultaneously, the vertically descending sliding plate 73 will drive the movable guide tube 83 to descend vertically within the guide sleeve 82 via the internal threaded sleeve 75. At this time, the guide sleeve 82 is in a fixed state (because the guide sleeve 82 and the sealing plug 81 are integrally formed, and the sealing plug 81 is in contact with the support plate 62). Consequently, the vertically descending movable guide tube 83 will align the strip-shaped hole 831 on the side wall with the guide hole 821. At this time, the spring 84 connected to the limiting ring 85 will be stretched, so that the water in the pool will enter the movable guide tube 83 through the water collection groove 61, the open guide tube 64 and the aligned strip hole 831, and then enter the sampling tube 4 through several drainage holes 832 opened along its length on the movable guide tube 83 (because the two ends of the movable guide tube 83 are closed, and the bottom end of the movable guide tube 83 is sealed to the lower opening of the strip hole 831, the water entering is prevented from accumulating and remaining at the bottom of the movable guide tube 83).

[0072] When a certain amount of water is injected into the sampling cylinder 4, the output rod of the control power unit 72 is retracted, causing it to slide upward in the water collection groove 61 via the sliding plate 73, thereby sealing the opening of the guide pipe 64. Meanwhile, the movable guide pipe 83 will rise vertically in the guide sleeve 82 (at this time, the spring 84 connected to the limit ring 85 will return to its initial state), causing the strip hole 831 to be misaligned with the guide hole 821, so that the strip hole 831 on the movable guide pipe 83 is in a blocked state, thus preventing the water collected in the sampling cylinder 4 from leaking through the movable guide pipe 83.

[0073] When it is necessary to remove the sampling tube 4 containing water from the collection tube 3, the suspension rod 52 should be rotated first so that the bottom tube of the movable guide tube 83 can be disengaged from the internal threaded sleeve 75 through the sampling tube 4. Then, the cross 51 should be pulled upward to remove the sampling tube 4 from the collection tube 3. Then, the water collected in the sampling tube 4 can be discharged for water quality testing as needed.

[0074] This design cleverly incorporates a movable sliding plate 73 within the collection cylinder 3. One end of the sliding plate 73 is fixedly connected to the sealing insert 65, while the center of the sliding plate 73 is detachably connected to the movable guide tube 83 via an internal threaded sleeve 75. This allows the sliding plate 73 to open or close the opening of the guide tube 64 when it moves up or down, and simultaneously aligns or offsets the strip hole 831 on the movable guide tube 83 with the guide hole 821. This ensures that the water in the pool can be accurately pumped into the sampling cylinder 4 for sampling. The sealed guide tube 64 prevents water from entering the collection cylinder 3, and the tightly sealed movable guide tube 83 prevents leakage of the water collected in the sampling cylinder 4.

[0075] In a preferred embodiment of this solution, the venting assembly 8 further includes a connecting conduit 86 installed on the top of the movable conduit 83, a sealing guide sleeve 87 installed on the top of the collecting cylinder 3 and in contact with the outer wall of the connecting conduit 86, and a key block installed on the outer wall of the connecting conduit 86 to restrict the rotation of the connecting conduit 86.

[0076] The connecting conduit 86 is located outside the collecting cylinder 3 with its opening in an open state, and several drainage holes 861 are arranged in a circular array on its wall. The key block and the keyway vertically opened on the sealing guide sleeve 87 cooperate with each other.

[0077] It should be noted that when the bottom tube of the movable conduit 83 needs to be threadedly connected to the inner threaded sleeve 75, the rotation of the sampling cylinder 4 will drive the movable conduit 83 to rotate synchronously through the keyway and key block, which will be connected to the connecting conduit 86, thus facilitating the accurate threaded connection of the movable conduit 83 to the inner threaded sleeve 75.

[0078] When the movable guide tube 83 descends vertically within the guide sleeve 82 (aligning the strip-shaped hole 831 with the guide hole 821), the movable guide tube 83 will drive the connecting guide tube 86 to descend synchronously, allowing the drainage hole 861 located within the sealed guide sleeve 87 to enter the sampling cylinder 4 near the bottom. Then, when water from the pool is forced into the sampling cylinder 4, excess air inside the sampling cylinder 4 will be discharged through the drainage hole 861 and the open top of the connecting guide tube 86 (achieving automatic pressure relief in the sampling cylinder 4), preventing air from entering during sampling. When water is continuously injected into the sampling tube 4, the air pressure inside the sampling tube 4 cannot be discharged normally, resulting in the sampling tube 4 being unable to collect a sufficient amount of water, which will affect the accuracy of water quality testing in the pool. After a certain amount of water is injected into the sampling tube 4 (a miniature liquid level sensor can be installed on the movable guide rod to detect the liquid level inside the sampling tube 4), the water level is located below the drainage hole 861 to prevent the water injected into the sampling tube 4 from being discharged through the drainage hole 861 and the connecting pipe 86.

[0079] When the movable guide tube 83 rises inside the sampling tube 4 (causing the strip hole 831 to be offset from the guide hole 821 and sealing the movable guide tube 83), the connecting guide tube 86 will rise synchronously inside the sealing guide sleeve 87 to block the guide hole 861 and prevent the water collected by the sampling tube 4 from leaking through the connecting guide tube 86 when the sampling tube 4 is taken out from the collection tube 3.

[0080] When it is necessary to remove the water collected in the sampling tube 4 for testing, it is not necessary to remove the sealing plug 81 from the opening of the sampling tube 4. The opening of the sampling tube 4 should be facing upwards. Then, connect the sampling bottle to the open end of the connecting tube 86, and pull the movable tube 83 upwards. At this time, the strip hole 831 will be connected to the guide hole 821. The drainage hole 861 on the connecting tube 86 will be located inside the sampling tube 4, which facilitates the injection of the water collected in the sampling tube 4 into the sampling bottle through the connecting tube 86. Since the strip hole 831 and the guide hole 821 are connected, airflow can be automatically injected into the sampling tube 4 through the movable tube 83, which facilitates the rapid flow and discharge of the water extracted in the sampling tube 4. The water collected in the sampling tube 4 can be diverted to multiple sampling bottles through the connecting tube 86 by reciprocating the movement of the movable tube 83, so as to achieve a thorough water quality test.

[0081] This solution cleverly incorporates a movable guide tube 83 and a connecting guide tube 86 that can be raised and lowered inside the sampling tube 4. When water is pressed into the sampling tube 4 through the movable guide tube 83, the connecting guide tube 86 can act as a pressure relief pipe to expel excess gas from the sampling tube 4. This prevents the sampling tube 4 from failing to collect a sufficient amount of water due to the inability of the gas pressure inside the sampling tube 4 to be properly released when water is continuously being pressed into it, which would affect the accuracy of water quality testing in the pool.

[0082] When it is necessary to drain the water in the sampling tube 4 through the connecting conduit 86, the movable conduit 83 can act as an airflow conduit 63, allowing outside air to enter the sampling tube 4, so that the water collected in the sampling tube 4 can be fully and quickly drained into multiple sampling bottles, enabling accurate detection and processing of the collected water samples.

[0083] In a preferred embodiment of this solution, the cross 51 is embedded in the notch groove opened at the top of the collection tube 3, and the top of the suspension rod 52 is movably installed in the center hole of the cross 51 through the cooperation of the threaded rod and the nut, and the top of the threaded rod is provided with a preferably hexagonal polygonal hole 521.

[0084] It should be noted that the detachable connection between the suspension rod 52 and the cross 51 allows for the replacement of suspension rods 52 of different lengths, and the sampling tube 4 can be installed at different heights of the collection tube 3. The suspension rod 52 can be twisted using tools such as a hex wrench, so that it drives the clamped sampling tube 4 to rotate through the collar 55 and the clamping plate 56, thereby facilitating the threaded connection between the movable guide tube 83 and the internal threaded sleeve 75.
