Abstract
Description
Technical Field
[0001] This utility model relates to the field of swimming pool water testing technology, and in particular to a multi-parameter water quality monitoring instrument. Background Technology
[0002] Swimming pools can be categorized into various types based on different needs and scenarios, such as indoor and outdoor pools. Indoor pools are typically equipped with a temperature control system, providing a comfortable swimming environment in any season, while outdoor pools rely more on natural climate conditions. During pool use, regular water quality checks are necessary, along with timely cleaning of debris from the pool bottom and maintaining a clean environment around the pool. An existing intelligent multi-parameter water quality monitor (publication number CN 219641311U) works by activating a sampling pump, which delivers the sample to three water tanks via a pumping pipe and a diversion pipe. A flow sensor detects the water flow data and transmits it to the main control box. The main control box analyzes and compares the data with the input values and then feeds back to the digital flow control valve. Adjusting the valve's opening gradually stabilizes the water flow to the three detection spaces in the detection chamber. Air bubbles in the sample are popped by a spike, and the water quality monitor analyzes the data, which is then uploaded to the main control box. However, this monitor has too many control components for the water sample, causing inconvenience and increasing the time required for subsequent maintenance. Utility Model Content
[0003] The purpose of this invention is to provide a multi-parameter water quality monitor in order to solve the above-mentioned problems.
[0004] This utility model achieves the above objectives through the following technical solutions:
[0005] The multi-parameter water quality monitor includes a housing with a cover at the front. A main control box is mounted on the cover, and a display screen is located on the front of the main control box. Inside the housing is a water storage mechanism for sampling pool water. A movable component for raising and lowering the monitor body is located on the upper side of the water storage mechanism. The water storage mechanism includes a water tank inside the housing, with an inlet pipe connected to the lower part of the tank. A water pump connected to the inlet pipe is located inside the housing. A one-way valve is installed on the inlet pipe between the water pump and the water tank. A drain valve is connected to the lower end of the water tank. Solenoid valves are installed on the water pipes and drain pipes. A through hole is opened on the upper surface of the water storage tank. An annular buoyancy plate is installed inside the water storage tank. A connecting rod is installed at the upper end of the annular buoyancy plate. A top plate is fixed at the upper end of the connecting rod. An upper limit switch and a lower limit switch are installed on the upper and lower sides of the top plate on the inner wall of the box. The moving component includes supports fixed on both sides of the inner wall of the box. A lead screw is installed on one support and a guide post is installed on the other support. A mounting plate is installed on the lead screw and the guide post. A servo motor is connected to the end of the lead screw. The monitor body is fixed on the mounting plate.
[0006] Further details: Three water storage tanks are installed adjacent to each other, and a connecting pipe is installed between the adjacent water storage tanks at the lower position.
[0007] Further settings: The diameter of the connecting pipe is larger than the diameter of the inlet pipe, and the connecting pipe and the inlet pipe are positioned horizontally at their centers.
[0008] Further configuration: The annular buoyancy plate is slidably connected to the water tank, and the monitor body is aligned with the center of the water tank.
[0009] Further configuration: The lead screw is rotatably connected to the support, the lead screw is threadedly connected to the mounting plate, and the mounting plate is slidably connected to the guide post.
[0010] Further features: Hooks are installed on the rear wall of the enclosure, and the top plate and mounting plate are staggered vertically.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] By incorporating a water storage mechanism and moving components, a water pump draws pool water into the storage tank through the inlet pipe. The water then supports the annular buoyancy plate, connecting rod, and top plate, causing them to move upwards until the top plate contacts the upper limit switch. At this point, the water pump stops, and a servo motor drives a lead screw to rotate, pushing the mounting plate downwards. This allows the monitor to be inserted into the water sample in the storage tank. After testing, the solenoid valve opens, draining the water from the tank. The annular buoyancy plate, connecting rod, and top plate then move downwards again until the top plate contacts the lower limit switch. The servo motor then rotates in the opposite direction, moving the mounting plate and monitor upwards to reset them. This simplified and time-saving testing process enhances overall convenience.

[0025] The present invention will be further described below with reference to the accompanying drawings:
[0026] like Figures 1-7 As shown, the multi-parameter water quality monitor includes a housing 1, a hook 11 on the rear wall of the housing 1, a cover 2 on the front of the housing 1, a main control box 3 on the cover 2, a main controller inside the main control box 3, a display screen 4 on the front of the main control box 3 for displaying monitoring data and parameter settings, a water storage mechanism for sampling pool water inside the housing 1, and a moving component for raising and lowering the monitor body 7 on the upper side of the water storage mechanism.
[0027] In this embodiment: the water storage mechanism includes a water tank 51 installed inside the housing 1. A water inlet pipe 53 is connected to the lower part of the water tank 51, and the water inlet pipe 53 is connected to the swimming pool. A water pump 54 connected to the water inlet pipe 53 is installed inside the housing 1. A one-way valve 55 is installed on the water inlet pipe 53 between the water pump 54 and the water tank 51 to prevent backflow of pool water. A drain pipe 56 is connected to the lower end of the water tank 51 to drain the water from the tank. A solenoid valve 57 is installed on the drain pipe 56. A through hole is opened on the upper surface of the water tank 51. An annular buoyancy plate 58 is installed inside the water tank 51. A connecting rod 59 is installed at the upper end of the annular buoyancy plate 58. A top plate 510 is fixed to the upper end of the connecting rod 59. Upper limit switches 50 are installed on the inner wall of the housing 1 on both sides above and below the top plate 510. 2 and the lower limit switch 501 are used to control the lifting position of the annular buoyancy plate 58; three water tanks 51 are arranged adjacently, and a connecting pipe 52 is arranged at the lower position between adjacent water tanks 51. The diameter of the connecting pipe 52 is larger than the diameter of the inlet pipe 53. The connecting pipe 52 and the inlet pipe 53 are arranged horizontally at their centers. The annular buoyancy plate 58 is slidably connected to the water tank 51. The monitor body 7 corresponds to the center of the water tank 51. The water pump 54 works to draw pool water into the water tank 51 through the inlet pipe 53. Water is injected into all water tanks 51 through the connecting pipe 52. The water in the water tank 51 floats the annular buoyancy plate 58, the connecting rod 59 and the top plate 510 and moves them upward as a whole. After the top plate 510 contacts the upper limit switch 502, the water pump 54 stops working.
[0028] In this embodiment: the moving component includes supports 61 fixed on both sides of the inner wall of the housing 1. A lead screw 62 is provided on one support 61, and a guide post 63 is provided on the other support 61. A mounting plate 64 is provided on the lead screw 62 and the guide post 63. A servo motor 65 is connected to the end of the lead screw 62. The monitor body 7 is fixed on the mounting plate 64. The lead screw 62 is rotatably connected to the support 61, and the lead screw 62 is threadedly connected to the mounting plate 64. The mounting plate 64 is slidably connected to the guide post 63. The top plate 510 is vertically offset from the mounting plate 64. When the top plate 510 contacts the upper limit switch 502, the water pump 54 stops pumping water into the water storage tank 51, and the servo motor 65 drives the water pump 54 to stop pumping water into the water storage tank 51. The lead screw 62 rotates, causing it to push the mounting plate 64 downward under the limit of the guide post 63, inserting the monitor body 7 into the water sample in the water tank 51. After the test is completed, the solenoid valve 57 opens, the water in the water tank 51 is discharged, and the annular buoyancy plate 58, connecting rod 59 and top plate 510 move downward as a whole. When the top plate 510 contacts the lower limit switch 501, the servo motor 65 rotates in the opposite direction, moving the mounting plate 64 and the monitor body 7 upward to reset. All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail in the text.
[0029] The working principle and usage process of this utility model are as follows: When it is necessary to test the pool water, the water pump 54 pumps the pool water into the storage tank 51 through the inlet pipe 53. The water lifts the annular buoyancy plate 58, the connecting rod 59, and the top plate 510 upward as a whole until the top plate 510 contacts the upper limit switch 502. The water pump 54 stops working, and the servo motor 65 drives the lead screw 62 to rotate, causing the lead screw 62 to push the mounting plate 64 downward under the limit of the guide post 63. The monitor body 7 is then inserted into the water sample in the storage tank 51. After the test is completed, the solenoid valve 57 opens, and the water in the storage tank 51 is discharged. The annular buoyancy plate 58, the connecting rod 59, and the top plate 510 move downward as a whole until the top plate 510 contacts the lower limit switch 501. The servo motor 65 rotates in the opposite direction, moving the mounting plate 64 and the monitor body 7 upward to reset.

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 claimed utility model.
