Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of circulating water quality testing, specifically relating to an analytical device for monitoring the quality of circulating water. Background Technology
[0002] Industrial circulating water systems are vital to industries such as energy, chemical, and metallurgy, and the stability of their water quality directly impacts equipment operating efficiency and energy consumption. Traditional manual sampling and laboratory analysis methods suffer from drawbacks such as long monitoring cycles and data lag, making it difficult to detect abnormal fluctuations in water quality in a timely manner. This can easily lead to problems such as heat exchanger scaling and accelerated pipe corrosion, resulting in an annual energy waste rate as high as 10%-15%. Therefore, the development of online water quality monitoring equipment is the result of the combined effects of environmental governance needs, policy pressures, and technological innovation, and its continued progress will provide core guarantees for global water security.
[0003] Chinese Patent Publication No. CN220983264U discloses an online analysis device for monitoring the quality of circulating water. The device includes a monitoring and analysis instrument body and an anti-tangling mechanism. The anti-tangling mechanism prevents the rope from tangling and knotting. The anti-tangling mechanism is located on one side of the monitoring and analysis instrument body and includes an anti-tangling component on that side. In this device, a turntable rotates, winding the connecting rope via a take-up wheel and driving a first pulley to rotate. The rotation of the first pulley, through a belt and a second pulley, drives a reciprocating screw to rotate. The reciprocating screw causes a slider to move back and forth, following the connecting rope. Ball bearings reduce the wear rate of the connecting rope on the slider, increasing the service life of the connecting rope and preventing tangling and knotting during winding, ensuring normal operation of the online analysis device for monitoring the quality of circulating water.
[0004] When in use, the monitoring probe is too close to the side of the monitoring analyzer body, which requires the monitoring analyzer body to be pushed very close to the edge of the pool. The monitoring analyzer body is prone to falling into the water surface when subjected to external force. In addition, the monitoring probe has no protective measures and is easy to be bumped by other objects during monitoring. The dirt in the water surface covering the probe will affect the water quality monitoring. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, this utility model proposes an analytical device for monitoring the quality of circulating water, so as to solve the technical problem that the lack of protective measures for the monitoring probe in the existing technology affects the inaccuracy of water quality monitoring parameters.

[0018] The take-up and release wheel connecting shaft is fixedly connected to one end of the take-up and release belt, and the other end of the take-up and release belt is fixedly connected to the monitoring probe mounting base.
[0019] The monitoring probe mounting base includes a connecting section, the upper end of which is fixedly connected to the other end of the take-up and take-down strap, and the lower end of which is fixedly connected to the upper end of the mounting section.

[0057] The working process of the analytical device used to monitor the quality of circulating water in this embodiment is as follows:
[0058] Connect the water quality monitoring device to an external power source and start the electric telescopic rod 301. The retraction of the electric telescopic rod 301 will cause the rack 302 to move downward. The downward movement of the rack 302 will cause the gear 303 to rotate. The rotation of the gear 303 will cause the adjusting shaft 304 to rotate. The rotation of the adjusting shaft 304 will cause the rotating plate 307 to swing. The swing of the rotating plate 307 will cause the horizontal arm 309 to swing. The swing of the horizontal arm 309 will position the monitoring probe 2 above the water surface to be monitored, making it convenient for the monitoring probe 2 to move down and extend into the water surface for water quality monitoring. The water quality will then be analyzed by the monitoring and analysis instrument body 1.
[0059] When the analytical device for monitoring the quality of circulating water is in operation, the pawl 405 on the ratchet 410 is disengaged and the knob 409 is turned counterclockwise. The counterclockwise rotation of the knob 409 will cause the take-up shaft 408 to rotate counterclockwise. The counterclockwise rotation of the take-up shaft 408 will cause the take-up component 402 to rotate counterclockwise. The counterclockwise rotation of the take-up component 402 will unwind the take-up belt 403. The unwinding of the take-up belt 403 will place the monitoring probe 2 into the water surface to be monitored. The pawl 405 is engaged in the tooth gap of the ratchet 410 by the torsion spring 406, thereby positioning the monitoring probe 2. The docking section 601 is pre-inserted into the docking groove 503, so that the monitoring probe protective cover 6 covers the monitoring probe 2. At the same time as the monitoring probe protective cover 6 covers the monitoring probe 2, the sleeve 605 contacts the locking block 504, which will cause the elastic connector 604 to open, and then cause the locking block 504 to lock into the sleeve 605, thus realizing the installation of the monitoring probe protective cover 6. During monitoring, the monitoring probe protective cover 6 can protect the monitoring probe 2 and prevent the monitoring probe 2 from being bumped. The filter screen 603 can filter the water to prevent dirt from covering the monitoring probe 2 and affecting the monitoring probe 2's monitoring of water quality and the monitoring analyzer body 1's analysis of water quality.
[0060] When the analytical device for monitoring circulating water quality is not in use, turning the knob 409 clockwise will rewind the take-up tape 403. The clockwise rotation of the knob 409 is unaffected by the pawl 405. Then, extend the electric telescopic rod 301 to fold the take-up tape 402, saving space. Pry the retainer 605 off the retainer block 504 to remove the monitoring probe protective cover 6. Clean the monitoring probe protective cover 6 and the filter screen 603 to prevent contamination from affecting the monitoring results.

The bottom end of the protective section (602) is provided with a filter screen (603). Multiple elastic connectors (604) are evenly arranged around the side wall of the protective section (602) near the docking section (601). The elastic connectors (604) are fixedly connected to the sleeve (605). The sleeve (605) is connected to the card block (504) so that the monitoring probe protective cover (6) is installed around the monitoring probe (2) to protect the monitoring probe (2).
