Description

Technical Field

[0001] This utility model relates to the field of multi-parameter water quality analyzer technology, and in particular to a multi-parameter water quality analyzer that can be used for online monitoring. Background Technology

[0002] Multi-parameter water quality analyzers used for online monitoring are instruments used to monitor multiple water quality parameters in water bodies in real time. These analyzers are usually installed in places such as rivers, lakes, reservoirs, sewage treatment plants, industrial discharge outlets, and drinking water supply systems to continuously collect water quality data and promptly detect changes in water quality, thereby helping management departments to take corresponding measures to protect water resources or ensure water supply security.

[0003] Chinese Patent Publication No. CN220603449U, published on March 15, 2024, discloses an integrated multi-parameter water quality analyzer, including a shell, a data acquisition unit, and a protective tube. The shell includes a pair of hemispherical shells, with multiple semi-tubes evenly spaced along the circumference of the opening edge of each hemispherical shell. When two hemispherical shells are assembled together, the corresponding semi-tubes on the hemispherical shells form a complete mounting tube. The data acquisition unit is installed inside the mounting tube, and the probe end of the data acquisition unit extends to the outside of the hemispherical shell. The protective tube is threaded onto the mounting tube and protects the data acquisition unit inside.

[0004] Existing multi-parameter water quality analyzers for online monitoring, as mentioned above, achieve relative stability of the sphere's position through the cooperation of a float and a traction rope. In practice, the existing traction rope is usually directly fixed between the float and the sphere, and the effective length of the traction rope is relatively fixed, which limits the depth to which the sphere can sink. This results in limited effectiveness of online monitoring using multi-parameter water quality analyzers. Therefore, there is an urgent need to develop a corresponding multi-parameter water quality analyzer for online monitoring to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-parameter water quality analyzer that can be used for online monitoring in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-parameter water quality analyzer for online monitoring includes a float, a shell, and a chip module. The shell includes an upper shell and a lower shell that are fixedly connected. The inner wall of the lower shell is fixedly connected to a TOC sensor, a turbidity sensor, a pH sensor, and an ORP sensor via four sets of mounting brackets. A winding chamber is fixedly connected to the top of the upper shell. The inner and outer walls of the winding chamber are respectively integrated with a rotating rod and a limiting component for axial limiting of the rotating rod. A winding drum is fixedly connected to the outer wall of the rotating rod, and a traction rope is fixedly connected between the winding drum and the float.

[0008] Preferably, the TOC sensor, turbidity sensor, pH sensor, and ORP sensor are all tilted, and the TOC sensor, turbidity sensor, pH sensor, and ORP sensor are all fixed to the multiple mounting brackets with screws.

[0009] Preferably, the TOC sensor, turbidity sensor, pH sensor and ORP sensor are all fitted with outer seats that are fixedly connected to the outer wall of the lower shell, and multiple sets of outer seats are screwed together with mesh sleeves on their outer walls.

[0010] Preferably, an outer sheet is fixedly connected to the outer wall of the upper shell, and the outer sheet is fixedly connected to the lower shell by a locking rod.

[0011] Preferably, a protruding ring is fixedly connected to the bottom of the upper shell, and the outer wall of the protruding ring is inserted into the top of the lower shell through a connecting groove.

[0012] Preferably, the limiting component includes a limiting sleeve fixedly connected to the outer wall of the winding chamber, a positioning rod screwed onto the inner wall of the top of the limiting sleeve, and the open end of the positioning rod abutting against the outer wall of the rotating rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the TOC sensor, turbidity sensor, pH sensor, and ORP sensor are fixed to four sets of mounting brackets, and then the corresponding mesh sleeves are screwed on. Next, the upper and lower shells are fixed by the cooperation of the outer plate and the locking rod. The traction rope is pulled so that the part wrapped around the outside of the winding drum extends out until the effective length of the traction rope on the outside reaches the specified requirement. Then, the positioning rod is rotated so that it is screwed into the limiting sleeve until the open end of the positioning rod abuts against the outer wall of the rotating rod, thereby positioning the winding drum and the rotating rod. At this time, the ball shell is dropped into the water body. The ball shell will continue to sink until the traction rope is taut. At this time, the TOC sensor, turbidity sensor, pH sensor, and ORP sensor can perform multi-parameter detection of the water body. The adjustable length traction rope improves the applicability of the multi-parameter water quality analyzer for online monitoring.

[0015] 2. In this application, the TOC sensor, turbidity sensor, pH sensor, and ORP sensor are all directly integrated onto the lower shell via corresponding mounting brackets. When performing maintenance on the chip module, it is not necessary to separate multiple sets of mesh sleeves. Furthermore, the multiple sets of TOC sensors, turbidity sensors, pH sensors, and ORP sensors are all installed at an angle, ensuring that the independent disassembly and assembly of the TOC sensors, turbidity sensors, pH sensors, and ORP sensors will not cause movement conflicts with the components on the chip module.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A multi-parameter water quality analyzer for online monitoring includes a float 4, a shell 1, and a chip module 13. The shell 1 includes an upper shell 101 and a lower shell 102 that are fixedly connected. The inner wall of the lower shell 102 is fixedly connected to a TOC sensor, a turbidity sensor, a pH sensor, and an ORP sensor through four sets of mounting brackets 14. The top of the upper shell 101 is fixedly connected to a winding chamber 2. The inner and outer walls of the winding chamber 2 are respectively integrated with a rotating rod 6 and a limiting component for axially limiting the rotating rod 6. The outer wall of the rotating rod 6 is fixedly connected to a winding drum 7, and a traction rope 3 is fixedly connected between the winding drum 7 and the float 4.

[0025] The TOC sensor, turbidity sensor, pH sensor, and ORP sensor are fixed to the four sets of mounting brackets 14 respectively. Then, the corresponding mesh sleeves 5 are screwed on. Next, the upper shell 101 and the lower shell 102 are fixed by the cooperation of the outer piece 11 and the locking rod 12. Pull the traction rope 3 so that the part wrapped around the outside of the winding drum 7 extends out until the effective length of the traction rope 3 on the outside reaches the specified requirement. Then, rotate the positioning rod 9 so that it is screwed into the limiting sleeve 8 until the open end of the positioning rod 9 abuts against the outer wall of the rotating rod 6, thereby positioning the winding drum 7 and the rotating rod 6. At this time, the ball shell 1 is dropped into the water body. The ball shell 1 will continue to sink until the traction rope 3 is taut. At this time, the TOC sensor, turbidity sensor, pH sensor, and ORP sensor can perform multi-parameter detection on the water body. The adjustable length traction rope 3 improves the applicability of the multi-parameter water quality analyzer for online monitoring.

[0026] It should be noted that the online monitoring multi-parameter water quality detection unit, which consists of chip module 13 and TOC sensor, turbidity sensor, pH sensor and ORP sensor, directly references the comparison file, and will not be elaborated here.

[0027] Specifically, such as Figure 2 and Figure 4 As shown, the TOC sensor, turbidity sensor, pH sensor, and ORP sensor are all tilted, and are fixed to the multiple mounting brackets 14 with screws. The TOC sensor, turbidity sensor, pH sensor, and ORP sensor are all directly integrated onto the lower shell 102 through their respective mounting brackets 14. When performing maintenance on the chip module 13, it is not necessary to separate the multiple mesh sleeves 5. Furthermore, the tilted installation of the multiple TOC sensor, turbidity sensor, pH sensor, and ORP sensor ensures that there will be no movement conflict with the components on the chip module 13 during the independent disassembly and assembly of the TOC sensor, turbidity sensor, pH sensor, and ORP sensor.

[0028] Specifically, such as Figure 2 and Figure 3As shown, the TOC sensor, turbidity sensor, pH sensor, and ORP sensor are all fitted with outer seats 16 that are fixedly connected to the outer wall of the lower shell 102. Multiple sets of outer seats 16 are screwed onto the outer walls of their respective outer surfaces to provide protection for the TOC, turbidity, pH, and ORP sensors. An outer piece 11 is fixedly connected to the outer wall of the upper shell 101, and this outer piece 11 is fixedly connected to the lower shell 102 via a locking rod 12, thus ensuring convenient assembly and disassembly of the upper shell 101 and the lower shell 102. A protruding ring 10 is fixedly connected to the bottom. The outer wall of the protruding ring 10 is inserted into the top of the lower shell 102 through a connecting groove 15, ensuring the tightness of the connection between the upper shell 101 and the lower shell 102. The limiting component includes a limiting sleeve 8 fixedly connected to the outer wall of the take-up chamber 2. A positioning rod 9 is screwed onto the inner wall of the top of the limiting sleeve 8, and the open end of the positioning rod 9 abuts against the outer wall of the rotating rod 6. The positioning rod 9 is rotated to screw onto the limiting sleeve 8 until the open end of the positioning rod 9 abuts against the outer wall of the rotating rod 6, thereby realizing the positioning of the take-up drum 7 and the rotating rod 6.

[0029] Working principle: The TOC sensor, turbidity sensor, pH sensor, and ORP sensor are fixed to the four sets of mounting brackets 14 respectively. Then, the corresponding mesh sleeves 5 are screwed on. Next, the upper shell 101 and lower shell 102 are fixed by the cooperation of the outer piece 11 and the locking rod 12. The traction rope 3 is pulled so that the part wrapped around the outside of the winding drum 7 extends out until the effective length of the traction rope 3 on the outside reaches the specified requirement. Then, the positioning rod 9 is rotated so that it is screwed into the limiting sleeve 8 until the open end of the positioning rod 9 abuts against the outer wall of the rotating rod 6, thereby positioning the winding drum 7 and the rotating rod 6. At this time, the ball shell 1 is dropped into the water. The ball shell 1 will continue to sink until the traction rope 3 is taut. At this time, the TOC sensor, turbidity sensor, pH sensor, and ORP sensor are activated by the locking rod 12. The sensor, pH sensor, and ORP sensor can perform multi-parameter detection of water. The adjustable-length traction rope 3 improves the applicability of the multi-parameter water quality analyzer for online monitoring. The TOC sensor, turbidity sensor, pH sensor, and ORP sensor are all directly integrated on the lower shell 102 through the corresponding mounting bracket 14. When performing maintenance on the chip module 13, it is not necessary to separate multiple sets of mesh sleeves 5. Moreover, the multiple sets of TOC sensor, turbidity sensor, pH sensor, and ORP sensor are all installed at an angle, so that during the independent disassembly and assembly of the TOC sensor, turbidity sensor, pH sensor, and ORP sensor, there will be no movement conflict with the components on the chip module 13.
