Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, and in particular to an online water quality testing device used in water supply equipment. Background Technology

[0002] When there is a risk of water quality fluctuations in drinking water scenarios, online water quality monitoring devices are needed. These include rural water supply where water sources are easily polluted, secondary water supply in communities with aging pipe networks, industrial production water with high water quality requirements, emergency water supply after disasters, drinking water scenarios for special groups such as schools and hospitals, and various water supply scenarios that need to cope with regulatory inspections. All these scenarios require monitoring devices to prevent safety hazards and ensure water use compliance.

[0003] The current detection devices mainly use conductivity sensors and optical sensors to detect water quality. If the detection pipeline is switched, there will still be water in the pipeline that was previously tested. However, the water inside the pipeline will affect the effect of subsequent new tests. Conventional detection devices are not convenient to quickly remove the water in the pipeline for stable testing and use a unified drive source to control the transport and removal of water in the pipeline. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides an online water quality detection device for use in water supply equipment.

[0005] This invention provides an online water quality monitoring device for use in water supply equipment, specifically comprising: a monitoring chamber, inside which a pump base is fixedly installed, and on top of the pump base a dual-purpose piston pump is fixedly installed. The dual-purpose piston pump body consists of two sets of piston cylinders, with a transmission frame fixedly installed between the two sets of piston cylinders; two sets of connecting blocks are fixedly installed below the outside of the two sets of piston cylinders, with two sets of control solenoid valves connected to the connecting blocks near the inner wall of the monitoring chamber, and an outlet fixedly installed on the outside of the other connecting block; and on one side of the monitoring chamber, above... A testing chamber is fixedly installed; an inspection chamber and a degassing chamber are fixedly installed inside the testing chamber, located below the testing chamber; a pipe connects the outlet and the top of the inspection chamber; a corrugated channel is fixedly installed inside the testing chamber, with interfaces on both sides of the bottom of the corrugated channel. These interfaces extend out of the testing chamber and connect to a cone-type check valve. An impeller-type flow meter is also connected between the outlet of the corrugated channel and the cone-type check valve. The bottom of the cone-type check valve is connected to the pipes of the outlet and the inspection chamber; a water outlet pipe is connected to the middle of one side of the degassing chamber.

[0006] Optionally, the testing chamber is provided with a rotating door on its exterior, and a display, control buttons and an emergency stop button are fixedly installed outside the door; an air outlet is provided in the rotating door, and a protective net is provided in the air outlet; a through hole for connecting pipes is provided on one side of the testing chamber.

[0007] Optionally, a drive motor is fixedly installed below the transmission frame, and two sets of transmission wheels are rotatably installed on both sides of the transmission frame. The two sets of transmission wheels are coaxially connected, and the rotor end of the drive motor is connected to the rotating shaft of the two sets of transmission wheels through bevel gear transmission. Eccentric sliding piles are fixedly installed outside each transmission wheel, and the positions of the eccentric sliding piles outside the two sets of transmission wheels are staggered. A piston rod is slidably installed inside the piston cylinder, and a reciprocating drive frame is fixedly installed on the top of each piston rod, with the eccentric sliding piles located inside the reciprocating drive frame. Annular one-way valves are fixedly installed on both sides of the bottom of the piston cylinder near the connecting block. A valve plate is slidably installed inside each annular one-way valve, and a notch structure is opened around the side of the valve plate. A spring is installed on one side of each valve plate.

[0008] Optionally, a power distribution box and a transmitting device are fixedly installed above the inside of the testing chamber. The transmitting device is located above the testing chamber and contains a transmitter and a processor.

[0009] Optionally, two pairs of conductivity sensors are installed and fixedly sealed at the top of the zigzag channel; a pyramidal chamber is integrally provided on one side of the zigzag channel, and an optical sensor is installed and fixedly sealed at the tip of the pyramidal chamber.

[0010] Optionally, an electric gate valve is provided below the detection box, and the electric gate valve is connected between two sets of cone-shaped check valves; an electric cylinder is mounted on the top of the electric gate valve, and a valve core is slidably provided on the top of the electric gate valve, and the extension end of the electric cylinder is fixedly connected to the valve core of the electric gate valve.

[0011] Optionally, the inspection chamber is an elliptical cylindrical structure, with a liquid level sensor installed and fixedly sealed at the top of the inspection chamber; the bottom of the inspection chamber and the bottom of the degassing chamber are connected by a pipe.

[0012] Optionally, the top of the degassing chamber is connected to a vent via a bent pipe, and the vent is aligned and fitted with the outlet. An inner slide valve is slidably installed inside the degassing chamber, and a buoyancy ring is fixedly installed inside the inner slide valve. The buoyancy ring is a hollow structure. A disc valve is fixedly mounted on the top of the inner slide valve, and the disc valve can block the bottom end of the vent pipe.

[0013] Optionally, the inner slide valve can block the connection between the water outlet pipe and the degassing chamber; when the disc valve blocks the bottom end of the vent pipe, the inner slide valve is higher than the connection between the water outlet pipe and the degassing chamber.

[0014] The beneficial effects are as follows:

[0015] The two conductivity sensors are connected to the processor. The two conductivity sensors sense the water flow resistance between them. If there are more impurities in the water, the conductivity will increase, thereby determining that the water quality is abnormal. The processor will send a feedback signal to warn the user. By using two pairs of conductivity sensors for calibration, the conductivity in the water can be detected more accurately.

[0016] By combining a dual-purpose piston pump with a single drive motor, the system achieves both water delivery and pipeline evacuation functions. The motor drives two sets of piston cylinders to work alternately via bevel gear transmission. This allows for stable water delivery during the testing process and also enables the intake of air to quickly drain residual water from the pipeline. No additional power components are required, which greatly simplifies the equipment structure and avoids interference from water accumulation on the test results, thereby improving testing efficiency and stability.

[0017] Utilizing the principle of air-driven water and equipped with a liquid level sensor to monitor the drainage status in real time, the residual water in the test chamber can be quickly emptied when switching test pipelines, eliminating cross-contamination of water quality in different pipelines from the source. Furthermore, through the precise linkage control of the cone-type check valve and the electric gate valve, the water flow direction is kept stable and there is no backflow during the water circuit switching process, ensuring the authenticity and accuracy of each test data, and adapting to multi-pipeline alternating test scenarios.

[0018] The device features a built-in degassing chamber with an automatic buoyancy exhaust structure that removes air bubbles from the water flow, preventing them from affecting the sensor's detection accuracy. The detection, metering, and reflux processes are completed automatically in one integrated manner. It is suitable for various scenarios such as rural water supply, secondary water supply in residential areas, and industrial production water. The equipment is equipped with a display and control buttons, making it easy to operate and meeting the detection needs and regulatory compliance requirements of different users.

[0035] The transmission frame 202 is fixedly mounted with a drive motor 203 below it. Two sets of transmission wheels 204 are rotatably mounted on both sides of the transmission frame 202. The two sets of transmission wheels 204 are coaxially connected. The rotor end of the drive motor 203 is connected to the shaft of the two sets of transmission wheels 204 through bevel gear transmission.

[0037] Two pairs of conductivity sensors 504 are installed and fixedly sealed at the top of the zigzag channel 501; a pyramidal chamber 505 is integrally provided on one side of the zigzag channel 501, and an optical sensor 506 is installed and fixedly sealed at the tip of the pyramidal chamber 505.

[0038] Among them, an electric gate valve 6 is installed below the detection box 5, and the electric gate valve 6 is connected between two sets of cone-type check valves 503; an electric cylinder is mounted on the top of the electric gate valve 6, and a valve core is slidably installed on the top of the electric gate valve 6, and the extension end of the electric cylinder is fixedly connected to the valve core of the electric gate valve 6.

[0040] The top of the degassing chamber 8 is connected to a vent 801 via a bent pipe, and the vent 801 is aligned and fitted with the outlet 103. An inner slide valve 802 is slidably installed inside the degassing chamber 8, and a buoyancy ring 803 is fixedly installed inside the inner slide valve 802.

[0041] Among them, the inner slide valve 802 can block the connection between the water outlet pipe 9 and the degassing chamber 8; when the pancake valve 804 blocks the bottom end of the pipe of the vent 801, the inner slide valve 802 is higher than the connection between the water outlet pipe 9 and the degassing chamber 8.

[0042] Testing process

[0043] Power-driven and water conveyance: The drive motor 203 is started, driving two sets of transmission wheels 204 to rotate synchronously via bevel gear transmission. The eccentric sliding pile 205, in its circumferential motion, drives two sets of reciprocating drive frames 206 to move in opposite directions, one set rising while the other descends. The reciprocating drive frames 206 drive the piston rod 207 to alternately rise and fall within the piston cylinder 201, achieving uninterrupted variable-volume conveying.

[0044] Piston rod 207 rises: negative pressure is formed in piston cylinder 201 to draw in water, and the water flows through the control solenoid valve 301 and the annular one-way valve 208 on one side to enter piston cylinder 201;

[0045] Piston rod 207 descends: the water pressure inside piston cylinder 201 increases and discharges water. The water flows through the annular one-way valve 208 on the other side and is output from the outlet 302, flowing into the pipeline connected to the inspection chamber 7 at the outlet 302.

[0046] Detection and Measurement: The electric gate valve 6 is closed 50%-100% as needed, generating resistance. The water flow is forced through the cone check valve 503 into the zigzag channel 501, and then output through the cone check valve 503 on the other side. During this process, the conductivity sensor 504 and the optical sensor 506 complete the detection, and the impeller flow meter 502 realizes the flow measurement. The greater the degree of closure of the electric gate valve 6, the faster the water flow velocity in the zigzag channel 501.

[0047] Subsequent processing and return: The water after testing flows sequentially into the inspection chamber 7 and the degassing chamber 8, and is finally discharged from the outlet pipe 9 and returned to the equipment pipeline.

[0048] Example 2: Pipeline switching operation

[0049] Preparation for purging: Before switching to test different pipelines, the residual water in test box 5 must be purged first;

[0050] Air-driven water venting: Close the control solenoid valve 301 currently connected to the water source, and open another set of control solenoid valves 301 with a dustproof structure; drive motor 203 continues to work, at which time piston cylinder 201 draws in air instead of water, the air is delivered to detection chamber 5, squeezes out the residual water in the chamber, and is discharged through water outlet pipe 9; liquid level sensor 701 monitors the venting process in real time, and a decrease in liquid level indicates that air has been discharged from detection chamber 5.

[0051] Removing air bubbles: After air enters the degassing chamber 8, it rises to the top and accumulates, causing the water level in the chamber to drop. The inner slide valve 802 and the buoyancy ring 803 fall due to gravity, blocking the water outlet pipe 9. The accumulated air is discharged to the outside through the air release port 801 and the air outlet 103, completing the purging before pipeline switching.

[0052] Resume detection status: After switching, restart the detection and repeat the normal detection process. Water flows back into the detection chamber 5 and squeezes out the internal air. After the air is continuously discharged, the water level in the degassing chamber 8 rises naturally, pushing the internal slide valve 802 and the buoyancy ring cylinder 803 to rise. The disc valve 804 simultaneously blocks the air release port 801, and the water outlet pipe 9 resumes conduction, and the water flows back normally.

[0053] Example 3: Signal Control and Operation Interface

[0054] Signal feedback: The impeller flow meter 502, conductivity sensor 504, optical sensor 506, and level sensor 701 are all connected to the processor of the transmitting device 4 through lines to transmit detection data and status signals in real time.

[0055] Automatic control: The processor has a preset control program that automatically adjusts the start-stop and operation parameters of components such as the control source solenoid valve 301, drive motor 203, and electric gate valve 6 based on the received signal feedback, while also completing subsequent signal transmission and command execution.

[0056] External operation: View the equipment's operating status and detection data through the display 102 outside the rotary door 101, set parameters and control operations through the control buttons, and press the emergency stop button to interrupt equipment operation in an emergency.

[0057] The specific usage and function of this embodiment: In this invention, during installation, a set of control solenoid valves 301 and the water outlet pipe 9 are connected to a water source, such as... Figure 1 It is connected to the water circuit of different equipment through branch pipes and valves that control the branch pipes individually. Another set of control solenoid valves 301 are equipped with filters or dust covers at their openings.

[0058] When testing a designated device, open its pipeline valve to allow water to flow into the testing device;

[0059] Start the drive motor 203, which drives the two sets of transmission wheels 204 to rotate synchronously through bevel gear transmission, causing the eccentric slide pile 205 to move circumferentially. The eccentric slide pile 205 drives the two sets of reciprocating drive frames 206 to move up and down. When one set of reciprocating drive frames 206 rises, the other set of reciprocating drive frames 206 falls. Through the up and down movement of the two sets of reciprocating drive frames 206, the piston rod 207 moves up and down alternately in the piston cylinder 201, producing a continuous variable volume conveying effect. When the piston rod 207 rises, water is drawn into the piston cylinder 201. The water enters the piston cylinder 201 through the control solenoid valve 301 and the annular check valve 208 on one side. When the piston rod 207 falls, the water is discharged from the piston cylinder 201 and output from the outlet 302 through the annular check valve 208 on the other side, flowing to the electric gate valve 6.

[0060] The electric gate valve 6 is closed 50%-100% as needed. The electric gate valve 6 generates resistance, and the water will pass through the cone check valve 503 and enter the zigzag channel 501, and then be output from the other end of the cone check valve 503. During this process, the conductivity sensor 504 and the optical sensor 506 are used for detection, and the impeller flow meter 502 is used for measurement. All of these are detected.

[0061] The two conductivity sensors 504 are connected to the processor. The two conductivity sensors 504 sense the water flow resistance between them. If there are more impurities in the water, the conductivity will increase, thereby determining the abnormal water quality. The processor will send a feedback signal to warn. By using two pairs of conductivity sensors 504 for calibration, the conductivity in the water can be detected more accurately.

[0062] Then, the water flows into the inspection chamber 7, then into the degassing chamber 8, and is discharged from the outlet pipe 9, flowing back into the equipment pipeline;

[0063] Before switching to test different pipelines, drain the water from test box 5.

[0064] When the control solenoid valve 301 of the connecting pipeline is closed and another set of control solenoid valves 301 is opened, the drive motor 203 will not suck in water but will suck in air. The air will then be introduced into the detection box 5, and the water in the detection box 5 will be squeezed out by the air and discharged from the outlet pipe 9. The liquid level sensor 701 can monitor the venting process. When the liquid level sensor 701 drops, it indicates that the air has been discharged.

[0065] After entering the degassing chamber 8, the air will rise and accumulate at the top inside the degassing chamber 8. When the water level in the degassing chamber 8 drops, the inner slide valve 802 and the buoyancy ring cylinder 803 will drop due to gravity, blocking the water outlet pipe 9. The air will then pass through the vent 801 and the air outlet 103 and be discharged to the outside.

[0066] Switching back at this point can prevent the previously accumulated water from affecting subsequent testing;

[0067] When testing again, repeat the initial steps to make the water squeeze the air out of the test chamber 5 again. After the air is continuously discharged, the water level in the degassing chamber 8 will rise naturally, and finally the inner slide valve 802 and the buoyancy ring cylinder 803 will rise. The air outlet 801 will be blocked by the pancake valve 804. At this time, the water can be discharged again through the water outlet pipe 9.

[0068] The impeller flow meter 502, conductivity sensor 504, optical sensor 506 and level sensor 701 are all connected to the processor in the transmitting device 4 for signal feedback, and are equipped with built-in programs to control the operation of other components and subsequent signal transmission.
