Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, and specifically relates to a water quality monitoring device for a secondary water supply pump house. Background Technique

[0002] The specific indicators of water quality monitoring mainly include chromaticity, turbidity, chemical oxygen demand, etc. For some index values, real-time data can be obtained by connecting various digital sensors, such as PH, dissolved oxygen, turbidity, and temperature, etc. There is also a part that relies on laboratory cultivation to obtain the final test data, and the water quality at the same location needs to be detected multiple times. This requires obtaining the required water samples through a water quality sampling device.

[0003] For example, Chinese Patent (CN219715435U) relates to an on-line water quality detection device for a secondary water supply pump house, belonging to the technical field of water quality monitoring. It includes a water diversion unit installed between a water tank and a water pump, and a water quality monitoring device for measuring the water quality of the sample water body introduced by the water diversion unit. The water diversion unit includes a water diversion pipe communicated with the inner bottom of the water tank and a water outlet pipe connected to the water inlet of the water pump. A buffer pipe is coaxially connected between the water diversion pipe and the water outlet pipe. The inner diameter of the buffer pipe is larger than that of the water outlet pipe. A partition is arranged in the buffer pipe to divide the inner cavity of the buffer pipe into a left cavity and a right cavity respectively. Beneficial effects: Solve the problem that the water quality detection device is easily impacted by high-pressure water flow, resulting in unstable performance of the water quality detection module, low service life, and low accuracy of detection results.

[0004] The above solution uses a driving component to push the partition to move in the buffer pipe to avoid the impact of high-speed water flow on the water quality monitoring device. However, the specific flow rate of the water body in the water diversion pipe cannot be known. Therefore, when adjusting the position of the partition, it does not have self-adaptability, which affects the accuracy of the water quality detection device. And the water body will be stored in the right chamber of the buffer pipe for a period of time, which results in that the water quality detection device can only monitor the water quality of the water body inside the right chamber. Therefore, it does not have real-time performance during monitoring. To solve the above problems, a water quality monitoring device for a secondary water supply pump house is proposed. Content of the Utility Model

[0005] To solve the above technical problems, a water quality monitoring device for a secondary water supply pump house is provided, which solves the problem that the current solution uses a driving component to push the partition to move in the buffer pipe to avoid the impact of high-speed water flow on the water quality monitoring device. However, the specific flow rate of the water body in the water diversion pipe cannot be known. Therefore, when adjusting the position of the partition, it does not have self-adaptability, which affects the accuracy of the water quality detection device. And the water body will be stored in the right chamber of the buffer pipe for a period of time, which results in that the water quality detection device can only monitor the water quality of the water body inside the right chamber. Therefore, it does not have real-time performance during monitoring.

[0006] To achieve the above objectives, the technical solution adopted by the present utility model is as follows: A water quality monitoring device for a secondary water supply pump house, comprising a water inlet pipe, an adjustment assembly, and a water outlet pipe. The adjustment assembly includes an adjustment pipe. The water inlet pipe is fixedly connected to the right side of the adjustment pipe through a flange, and the water outlet pipe is fixedly connected to the left side of the adjustment pipe through a flange. An observation pipe is fixedly connected above the water inlet pipe, and the observation pipe communicates with the water inlet pipe. A rotor fan blade is rotatably connected inside the observation pipe. The rear end of the rotor fan blade penetrates the rear side wall of the observation pipe and is fixedly connected to a rotating disk. A display groove is formed on the side surface of the rotating disk. A fixing plate is fixedly connected to the upper end of the rear side of the observation pipe, and a rotational speed sensor is fixedly installed inside the fixing plate. The detection end of the rotational speed sensor is located directly above the display groove. A control box is fixedly installed on the top of the observation pipe.

[0007] Preferably, four fixing rods are fixedly connected to both the left and right sides inside the adjustment pipe. An installation column is fixedly connected to the middle of the eight fixing rods, and a fixing disk is fixedly connected to the middle of the outer surface of the installation column.

[0008] Preferably, a number of rotating sleeves are fixedly connected to the edge of the fixing disk, and adjustment blades are rotatably connected inside the rotating sleeves.

[0009] Preferably, a number of rotating shafts equal to the number of adjustment blades are rotatably connected to the middle of the outer surface of the adjustment pipe. The rotating shafts are fixedly connected to the ends of the adjustment blades away from the rotating sleeves inside the adjustment pipe, and a driving rod is fixedly connected to the outside of the adjustment pipe and the rotating shaft.

[0013] Compared with the prior art, the advantages of the present utility model are as follows: The present utility model drives the rotating disk to rotate synchronously through the rotating shaft of the rotor fan blade. The rotational speed sensor detects the time for each rotation of the display slot to judge the current water flow velocity, and transmits the flow velocity information to the control box. The control box controls the opening and closing of the regulating motor according to the flow velocity information, so as to adaptively control the flow velocity and flow rate of the water body. The adaptive flow velocity regulation ensures the stability of the water flow velocity during water quality detection, can reduce errors, and improve the accuracy of water quality detection. Extreme flow velocities may cause erosion or sediment blockage to the water quality monitoring probe, affecting its long-term stability and service life. By adjusting the water flow velocity, over-impact or blockage on the monitoring equipment can be avoided, protecting its normal operation. Combining the flow velocity monitoring with the water quality monitoring forms a closed-loop control system. This system can sense the water flow state in real time and make corresponding adjustments to ensure that the water quality monitoring process is always in the best state, thereby improving the performance and reliability of the entire water supply system.

[0027] Working principle: When in use, the device is connected to the pipeline of secondary water supply. Water flows in from the water inlet pipe 1, driving the rotor fan blade 3 to rotate. The rotor fan blade 3 drives the rotating disk 4 to rotate synchronously through the rotating shaft. The rotation speed sensor 7 detects the time for each rotation of the display slot 5 to judge the current water flow rate, and transmits the flow rate information to the control box 8.
