Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to an online residual chlorine monitoring device. Background Technology

[0002] Traditional online residual chlorine monitoring devices typically employ a fixed installation method, where the residual chlorine sensor probe is fixed at a specific depth. While this method is simple in structure, it has several limitations in practical applications. For example, in environments with significant water level fluctuations, such as water treatment plants, swimming pools, or sewage treatment plants, fixed probes cannot flexibly adjust the detection depth according to water level changes, leading to potentially inaccurate measurement results that fail to accurately reflect the residual chlorine concentration in the water. Furthermore, traditional online monitoring devices are often non-removable, requiring substantial time and manpower for maintenance or replacement, increasing operating costs and technical complexity. Therefore, we propose an online residual chlorine monitoring device. Utility Model Content

[0003] The main objective of this invention is to provide an online residual chlorine monitoring device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An online residual chlorine monitoring device includes a base plate, a vertical plate fixedly installed at the upper center of the base plate, ground nails inserted at the four corners of the upper end of the base plate, a sliding groove at the rear end of the vertical plate, a lifting mechanism slidably connected in the sliding groove, a residual chlorine sensor probe inserted at the upper end of the lifting mechanism, a mounting frame fixedly installed at the upper front end of the vertical plate, the mounting frame having a U-shaped structure, two slots on the upper and lower inner walls of the mounting frame, an online monitor slidably installed in the mounting frame through the slots, an electrical wire connecting the online monitor and the residual chlorine sensor probe, and a protective top plate fixedly installed at the upper end of the mounting frame, the upper surface of the protective top plate being lower in the front and higher in the back, the upper surface of the protective top plate being designed with an inclined angle that is lower in the front and higher in the back, so that even in rainy weather, rainwater will flow away along the inclined surface and will not accumulate on the top of the equipment, reducing the risk of water seepage into the interior;

[0006] The online monitor has two integrated clips at its upper and lower ends that work with the slots. It also has snap-fit ​​slots at both the left and right ends, making it easy to operate. The structure is simple and the design is reasonable.

[0007] Preferably, the rear end of the upright plate has a motor mounting groove, which is located below the slide groove. Two slide rails are fixedly installed at the rear end of the upright plate, and two ground nails are located on the left and right sides of the slide groove, respectively.

[0008] Preferably, the lifting mechanism includes a forward and reverse motor, which is fixedly installed in a motor mounting slot. A lead screw is fixedly installed at the output end of the forward and reverse motor and is movably installed in a slide groove. A slider is threadedly connected to the lead screw and is slidably connected to the slide groove. A connecting plate is fixedly installed at the rear end of the slider, and a support plate is fixedly installed at the rear end of the connecting plate.

[0009] By adopting the above technical solution: using a forward and reverse motor to drive the lead screw to rotate, as the lead screw rotates, the slider moves up and down along the slide groove. The slider drives the connecting plate and the support plate to move together, so that the residual chlorine sensor probe fixed under the support plate can be accurately adjusted to the required water depth position. This allows users to accurately adjust the position of the sensor probe according to different water depths and monitoring needs. Compared with the traditional fixed installation method, this flexibility significantly improves the accuracy of residual chlorine concentration measurement and ensures the authenticity and reliability of the data.

[0010] Preferably, the lower end of the residual chlorine sensing probe passes through the support plate and extends below the support plate, and the upper part of the residual chlorine sensing probe is fixedly installed to the support plate by bolts.

[0011] By adopting the above technical solution, the residual chlorine sensing probe and the support plate are detachable, which facilitates replacement and reduces maintenance costs.

[0012] Preferably, the front left and right sides of the connecting plate are provided with guide grooves that cooperate with the slide rails, and the two guide grooves are slidably connected to the two slide rails respectively to slide the connecting plate onto the rear end of the upright plate.

[0013] By adopting the above technical solution, the guide groove and the slide rail on the upright plate are used in conjunction to ensure the stability and straightness of the connecting plate during movement.

[0014] Preferably, the two card strips located at the same height are slidably connected in the corresponding two card slots to fix the online monitor in the mounting frame.

[0015] By adopting the above technical solution, the online monitor is fixed by the cooperation of the clip and the slot in the mounting bracket. Users can easily take out or insert the online monitor through the slot without complicated tools or professional skills.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The lifting mechanism design allows for height adjustment of the residual chlorine sensor probe. This design enables users to precisely adjust the probe's position according to different water depths and monitoring needs. Compared to traditional fixed installation methods, this flexibility significantly improves the accuracy of residual chlorine concentration measurements, ensuring the authenticity and reliability of the data. Especially in environments with frequent water level changes, such as waterworks, swimming pools, or sewage treatment plants, it can adapt to water level changes promptly, providing more stable and consistent monitoring results.

[0018] 2. The detachable design of the online monitor and mounting bracket greatly simplifies the equipment maintenance and replacement process. The online monitor is secured by clips that engage with slots within the mounting bracket, allowing users to easily remove or insert the monitor without requiring complex tools or specialized skills. This modular design not only shortens maintenance time and reduces downtime, but also lowers maintenance costs and technical barriers, making daily operation and maintenance more efficient and economical.

[0029] In this embodiment, the upper and lower ends of the online monitor 8 are integrally formed with two clips 81 that cooperate with the slots 71, and the left and right ends of the online monitor 8 are provided with buckle slots 82; the two clips 81 located at the same height are slidably connected in the corresponding two slots 71 to fix the online monitor 8 in the mounting bracket 7.

[0030] The above solution, through the detachable design of the online monitor 8 and the mounting bracket 7, greatly simplifies the equipment maintenance and replacement process. The online monitor 8 is fixed in place by a locking strip 81 and a slot 71 within the mounting bracket 7. Users can easily remove or insert the online monitor 8 using the clip 82, without requiring complex tools or specialized skills. This modular design not only shortens maintenance time and reduces downtime, but also lowers maintenance costs and technical barriers, making daily operation and maintenance more efficient and economical.

[0031] In this embodiment, a motor mounting slot 31 is provided at the rear end of the upright plate 3, and the motor mounting slot 31 is located below the slide groove 4. Two slide rails 32 are fixedly installed at the rear end of the upright plate 3, and two ground nails 2 are located on the left and right sides of the slide groove 4 respectively. The lifting mechanism 5 includes a forward and reverse motor 51, which is fixedly installed in the motor mounting slot 31. A lead screw 52 is fixedly installed at the output end of the forward and reverse motor 51, and the lead screw 52 is movably installed in the slide groove 4. A slider 53 is threadedly connected to the lead screw 52, ​​and the slider 53 is connected to the slide groove. 4. Sliding connection: A connecting plate 54 is fixedly installed at the rear end of the slider 53, and a support plate 55 is fixedly installed at the rear end of the connecting plate 54; the lower end of the residual chlorine sensing probe 6 passes through the support plate 55 and extends to the bottom of the support plate 55, and the upper part of the residual chlorine sensing probe 6 is fixedly installed to the support plate 55 by bolts; the front left and right sides of the connecting plate 54 are provided with guide grooves 541 that cooperate with the slide rail 32, and the two guide grooves 541 are slidably connected to the two slide rails 32 respectively to slide the connecting plate 54 to the rear end of the vertical plate 3.

[0032] The above-described solution utilizes the lifting mechanism 5 to allow for height adjustment of the residual chlorine sensor probe 6. This design enables users to precisely adjust the probe's position according to different water depths and monitoring needs. Compared to traditional fixed installation methods, this flexibility significantly improves the accuracy of residual chlorine concentration measurements, ensuring the authenticity and reliability of the data. Especially in environments with frequent water level changes, such as waterworks, swimming pools, or sewage treatment plants, it can adapt to water level fluctuations promptly, providing more stable and consistent monitoring results.

[0033] It should be noted that this utility model is an online residual chlorine monitoring device. When monitoring the residual chlorine in tap water in a water tank, firstly, the base plate 1 is firmly fixed to the ground at the edge of the water tank using the ground nails 2 at the four corners of the base plate 1 to ensure the stability of the entire device. The upright plate 3 is vertically installed on the base plate 1 to provide structural support for subsequent components. Next, the forward and reverse motor 51 installed in the motor mounting slot 31 is started. The forward and reverse motor 51 drives the lead screw 52 to rotate. As the lead screw 52 rotates, the slider 53 moves up and down along the slide groove 4. The slider 53 drives the connecting plate 54 and the support plate 55 to move together, so that the residual chlorine sensor 6 fixed below the support plate 55 can be accurately adjusted to the required water depth position. At the same time, the front end of the connecting plate 54 is provided with guides on the left and right sides. The guide grooves 541, which work in conjunction with the slide rails 32 on the vertical plate 3, ensure the stability and straightness of the connecting plate 54 during movement. Once the residual chlorine sensor 6 reaches the predetermined depth, it begins to detect the residual chlorine concentration in the water and transmits the collected data in real time to the online monitor 8 inside the mounting frame 7 via the wire 9. The online monitor 8 is not only responsible for receiving and processing the data from the residual chlorine sensor 6, but can also upload the monitoring results to a remote server via a built-in communication module (such as Wi-Fi, GPRS, etc.) so that staff can check the water quality at any time. Both the online monitor 8 and the residual chlorine sensor 6 are existing technologies, and their working principles and data upload to the remote server are existing technologies, which will not be elaborated on here. In addition, to protect the online monitor 8 from the influence of the external environment, a protective top plate 10 is installed on the upper end of the mounting frame 7. The upper surface of the protective top plate 10 is designed with a slope angle that is lower in the front and higher in the back. In this way, even in rainy weather, rainwater will flow away along the slope and will not accumulate on the top of the equipment, reducing the risk of water seepage into the interior. When maintenance or replacement of the online monitor 8 is required, the user can pull the online monitor 8 forward through the latch 82 and slide it out of the latch 71 on the inner wall of the mounting frame 7 using the locking strips 81 at the upper and lower ends of the online monitor 8. This makes it easy to remove the online monitor 8, which is convenient for installation, disassembly, replacement and maintenance, and reduces the time cost and technical difficulty of on-site maintenance.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
