Description

Technical Field

[0001] This utility model relates to the technical field of residual chlorine monitoring equipment, specifically an online residual chlorine monitoring device. Background Technology

[0002] Residual chlorine refers to the effective chlorine remaining in water after chlorination disinfection and contact for a certain period of time. It includes free residual chlorine and combined residual chlorine, which can be used to inhibit the reproduction of microorganisms in water and ensure continuous sterilization ability. Online monitoring devices are devices that monitor the residual chlorine content in water in real time. They continuously collect water samples through sensors and other components, and after analysis and processing, display the residual chlorine concentration data in real time, realizing the monitoring of water quality residual chlorine indicators. They are commonly used in drinking water, sewage treatment and other scenarios to ensure water quality safety.

[0003] For example, a Chinese patent document discloses an online monitoring device for residual chlorine in marine cooling water (publication number: CN209342711U). This patent uses a floating module connected to the upper part of the instrument compartment and an underwater anchoring module connected to the instrument compartment to fix the entire online monitoring device in the water with its upper part exposed. This allows for real-time online monitoring of residual chlorine in the marine cooling water via a residual chlorine probe inserted into the water. The monitored data is transmitted to the acquisition and control circuit, and then wirelessly to the observation terminal, enabling corresponding processing based on the real-time monitoring data. However, in use, suspended solids and particulate impurities in the water may clog the detection end or adhere to the probe, causing detection signal deviation. With prolonged use, impurity accumulation necessitates frequent probe disassembly and cleaning, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide an online residual chlorine monitoring device in order to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online residual chlorine monitoring device, comprising: an online detector body, a port fixedly connected to one bottom end of the online detector body, an internally threaded locking tube fixedly connected to the other bottom end of the online detector body, a connector mechanism provided inside the internally threaded locking tube, a wire provided at one end of the connector mechanism, a residual chlorine sensor fixedly connected to one end of the wire, and a protective mounting mechanism provided on the outside of the residual chlorine sensor.

[0006] As a further embodiment of this utility model: the connector mechanism includes a port connector and a fixing block. The port connector is movably inserted into the port and fixedly connected to the line body. The fixing block is fixedly connected to one end of the port connector. It also includes an external threaded connecting pipe, a rotating pipe, and a limiting protrusion ring. The external threaded connecting pipe is threaded into the internal threaded locking pipe. The rotating pipe is fixedly connected to the tail end of the external threaded connecting pipe, and the limiting protrusion ring is fixedly connected to the tail end of the rotating pipe.

[0007] As a further embodiment of this utility model: the installation and protection mechanism includes a fixed frame, a protective tube, and a mounting plate. The fixed frame is fixedly connected to one end of the outer side of the residual chlorine sensor, the protective tube is threadedly connected to one end of the bottom of the fixed frame, and the mounting plate is fixedly connected to one end of the top of the fixed frame; a threaded ring and a filter screen are also included, with the threaded ring threadedly connected to the bottom of the protective tube and the filter screen fixedly connected to the inner side of the threaded ring.

[0008] As a further improvement of this utility model: the front of the online testing instrument body is provided with a display screen, and the front of the online testing instrument body is provided with operation buttons located below the display screen.

[0009] As a further embodiment of this utility model: the external threaded connecting pipe and the rotating pipe are slidably connected to the fixed block, and the tail end of the fixed block is provided with a groove for inserting a limiting protrusion ring.

[0010] As a further improvement of this utility model: the number of mounting plates is provided in two sets, and the other set of mounting plates is located on the side of the fixed frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the online detector achieves circuit conduction through port plug-in. Squeezing the rotating tube engages the external threaded connecting tube with the internal threaded locking tube, while a limiting protrusion ring embeds into the groove of the fixing block, forming a double mechanical locking mechanism of "threaded tightening + circumferential limiting." This resists water flow or vibration, preventing the port connector from loosening or falling off. Two mounting plates can be located on the top and side of the fixed frame, respectively, and are fixed to the water pipe or monitoring equipment bracket with bolts. This supports horizontal or vertical installation, adapting to complex field environments and improving the device's installation flexibility and scenario adaptability. After the residual chlorine sensor is fixed to the fixed frame, a protective tube is installed to cover its lower part to prevent collisions with objects in the water. The filter screen inside the bottom threaded ring filters impurities in the water, intercepting suspended solids and particles, preventing blockage of the sensor's detection end and detection signal deviation caused by impurities, ensuring accurate residual chlorine concentration data. Furthermore, the protective tube, threaded ring, and filter screen can all be quickly disassembled for cleaning or replacement, reducing maintenance difficulty. Attached Figure Description

[0018] Reference Figure 1 and Figure 5 The installation and protection mechanism 7 includes a fixed frame 71, a protective tube 72, and a mounting plate 73. The fixed frame 71 is fixedly connected to one end of the outer side of the residual chlorine sensor 6, the protective tube 72 is threadedly connected to one end of the bottom of the fixed frame 71, and the mounting plate 73 is fixedly connected to one end of the top of the fixed frame 71.

The residual chlorine sensor 6 is then fixed by the fixing frame 71, and the protective tube 72 is installed below the fixing frame 71 to cover the lower part of the residual chlorine sensor 6 to prevent collision with objects in the water. The threaded ring 74 is then installed at the bottom of the protective tube 72, and the filter screen 75 inside the threaded ring 74 filters impurities in the water, intercepting suspended solids and particulate impurities in the water to prevent them from clogging the sensor detection end and avoiding detection signal deviation caused by impurity adhesion, thus ensuring the accuracy of residual chlorine concentration data. Moreover, the protective tube 72, threaded ring 74, and filter screen 75 can all be quickly disassembled for cleaning or replacement, reducing maintenance difficulty.
