[0002] Chlorine is a core method for drinking water disinfection, effectively killing pathogens such as bacteria and viruses and preventing waterborne diseases. However, excessive chlorine can irritate the respiratory tract and skin, and long-term ingestion may generate harmful byproducts, endangering health and damaging aquatic ecosystems. Monitoring chlorine levels ensures a balance between disinfection effectiveness and safety, optimizes water treatment processes, avoids exceeding or falling below standards, and complies with environmental regulations, thus protecting public drinking water safety and ecological stability.

[0003] When chlorine is injected into a water tank for disinfection, the chlorine content varies in different water layers, necessitating testing at each layer. For example, patent publication number CN220171012U discloses a residual chlorine detection device for flowing water.

After testing at one depth, the water in the cylinder is discharged, and the same method is used to test water at other depths. However, because the piston exerts pressure on the top of the cylinder when it rises, and the top of the cylinder is sealed, if the drive motor forcefully pulls the piston upwards, it can easily generate high pressure, damaging the residual chlorine detector and affecting normal testing.

[0024] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0025] See Figures 1 to 4This utility model provides a water quality residual chlorine content detection device, including a detection box 1, a residual chlorine detector 2 connected to the top surface of the detection box 1, the detection end of the residual chlorine detector 2 extending into the interior of the detection box 1, a support frame 3 provided on the side of the detection box 1, a drive pump 4 provided on the top surface of the support frame 3, the output end of the drive pump 4 being connected to the side wall of the detection box 1 through a connecting pipe 5, a depth braking mechanism provided on the side of the drive pump 4, the depth braking mechanism being activated by a drive motor, and a sampler connected to its traction end, the sampler being able to extend into the water pool at different depths to collect water samples.

[0026] It should be noted that both the testing box 1 and the sampler are made of plastic.

[0027] Specifically, the testing box 1 is placed next to the water pool to be tested, and the sampler is placed in the pool. The sampler is then moved to different heights in the water by activating the depth braking mechanism. Subsequently, the drive pump 4 is activated to generate negative pressure, which works on the sampler, drawing chlorine-containing water samples from the pool. These samples then flow into the connecting pipe 5 and finally into the testing box 1. The residual chlorine detector 2 on the top of the testing box 1 detects the residual chlorine content of the extracted water sample. During the water sampling process, the drive pump 4 is located on the shore and works in conjunction with the depth braking mechanism to quickly extract the water sample, ensuring the quality of the water sample extraction. This also solves the technical problem of existing equipment where the piston rises, creating pressure on the top of the cylinder, which is sealed. If the drive motor forcefully pulls the piston upwards, it can easily generate high pressure that damages the residual chlorine detection head, affecting normal testing operations.

[0028] Preferably, the drive pump 4 is a peristaltic pump, the output end of which is connected to the through pipe 5, and the input end is connected to the depth braking mechanism.

[0029] In this embodiment, a peristaltic pump is used to extract chlorine-containing water to avoid the chlorine-containing water reacting with metals and affecting the accuracy of subsequent residual chlorine detection by the residual chlorine detector 2.

[0030] Preferably, the deep braking mechanism includes a drive motor (not shown), the output shaft of which is connected to a manifold 6, a water pipe 7 is wound around the manifold 6, a fixed pulley 8 is rotatably provided at the end of the support frame 3, one end of the water pipe 7 is connected to the input end of the peristaltic pump, and the other end is placed on the top surface of the fixed pulley 8 and connected to a sampler.

[0031] It should be noted that the drive motor can be a YS6324B14 model motor.

[0032] In this embodiment, the drive motor is started, and its output shaft drives the manifold 6 to rotate, which, with the support of the fixed pulley 8, lowers the sampler into the water tank via the water pipe 7. As the drive motor extends the length of the water pipe 7, the sampler can take samples at different depths within the water tank.

[0033] Preferably, the sampler includes a water head 9, the top of which is connected to a water pipe 7, and a filter is detachably connected to the bottom.

[0034] In this embodiment, when the drive pump 4 starts working, it generates negative pressure in the water pipe 7, thereby connecting the water head 9 and the filter section, drawing the water sample out of the water tank, and then through the drive pump 4 and the pipe 5 into the detection box 1.

[0035] Furthermore, the filtration unit includes a filter cylinder 10, which is threadedly connected to the water intake head 9, and a filter plate 11 is provided on the top surface of the filter cylinder 10.

[0036] It should be noted that the filter cartridge 10 and the water inlet head 9 are connected by a thread and can be easily disassembled to clean the filter cartridge 10, so as to avoid excessive adhesion and reaction with chloride ions when passing through the filter cartridge 10, which would affect the accuracy of the chlorine content detection.

[0037] In this embodiment, after the water sample enters from the bottom of the filter cylinder 10, the mesh cover and filter plate 11 inside the filter cylinder filter impurities from the water sample, thereby improving the purity of the water sample and preventing too many impurities from entering the detection box 1, causing slight pollution and affecting subsequent use.

[0038] Preferably, the detection box 1 includes a first cavity 12 and a second cavity 13. The inner side of the first cavity 12 is provided with two water guide slopes 14. The water guide slopes 14 are used to hold water samples and supply them to the detection end of the residual chlorine detector 2 for detection. A partition 15 is provided between the first cavity 12 and the second cavity 13. The partition 15 is provided with water passage holes 16 that communicate with the first cavity 12.

[0039] In this embodiment, the first chamber 12 is used to receive the water sample to be tested. When the extracted water sample passes through the through pipe 5, it is guided by the guide slope 14 and flows slowly, steadily, and uniformly into the first chamber 12, improving the accuracy of the residual chlorine detector 2 in detecting the true chlorine content of the water. After the test is completed, the water sample from the first chamber 12 can be transferred to the second chamber 13 for storage via the partition 15.

[0040] Optionally, the second cavity 13 is located below the first cavity 12, and the bottom side wall of the second cavity 13 is provided with a water outlet switch 17, and the top is connected to the first cavity 12 through a water passage hole 16.

[0041] It should be noted that the water outlet switch 17 can be a DN15 PVC-U external thread ball valve faucet.

[0042] In this embodiment, the second chamber 13 can accommodate water samples at different depths in different pools. After all testing is completed, the water outlet switch 17 is opened to drain the water, preventing bacterial growth inside the testing chamber 1 due to prolonged storage.

[0043] Optionally, a sliding water-blocking mechanism is provided inside the partition 15. One end of the sliding water-blocking mechanism contacts the inner wall of the water passage 16, and the other end extends out of the first cavity 12.

[0044] In this embodiment, when it is necessary to drain the water sample from the first cavity 12, grasp the end of the sliding water-cutting mechanism that extends outside the first cavity 12 and pull it forcefully to open the water passage 16. The water sample falls from the water passage 16 into the second cavity 13 for temporary storage.

[0045] Optionally, the sliding water-blocking mechanism includes a baffle 18, which is integrally connected with a toothed plate 19. One end of the toothed plate 19 extends outside the second cavity 13, and its top surface contacts a toothed assembly.

[0046] In this embodiment, by grasping the rod outside the first cavity 12 and forcefully pulling out the toothed plate 19, the wings drive the baffle 18 to gradually detach from the water passage 16, allowing the water sample in the first cavity 12 to fall freely into the second cavity 13. When the pulling out of the toothed plate 19 stops, the locking tooth assembly engages with the teeth of the toothed plate 19, forming a locking action to prevent the toothed plate 19 from sliding freely. When the toothed plate 19 is pushed to slide within the partition 15, the baffle 18 gradually closes the water passage 16 to facilitate subsequent water storage in the first cavity 12. After the toothed plate 19 pushes the side wall of the baffle 18 into close contact with the side wall of the water passage 16, the locking tooth assembly stably engages with the toothed plate 19, preventing the toothed plate 19 from sliding freely and causing the baffle 18 to move, thus affecting the stability of the baffle 18's water interception.

[0047] Furthermore, the tooth assembly includes a fixing block 20, a fixing cylinder 21 on the bottom surface of the fixing block 20, a spring 22 inside the fixing cylinder 21, a locking block 23 connected to the bottom end of the spring 22, and the locking block 23 engaging with the tooth plate 19.

[0048] In this embodiment, when the toothed plate 19 is pulled out or pushed forward, under the action of external force, the teeth of the toothed plate 19 can press against the locking block 23, and the locking block 23 compresses the spring 22, allowing the toothed plate 19 to slide freely. Under the action of no external force, the rebound of the spring 22 pushes the locking block 23 into the tooth groove, which plays a role in locking and stabilizing the toothed plate 19.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
