Detailed Implementation
[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.
[0042] Please see Figures 1-5 In one embodiment of this application, a water pump operation fault detection and feedback device includes a main drainage tank 1, a secondary drainage tank 2, a filter screen 3, and a controller 21. The secondary drainage tank 2 is slidably inserted into the main drainage tank 1, and the two are connected by a thread. The filter screen 3 is disposed inside the main drainage tank 1, and the controller 21 is disposed on the main drainage tank 1. The feedback device further includes:
[0043] The monitoring module, which is installed in the drainage auxiliary tank 2, is used to monitor the flow rate of water; and
[0044] The feedback module, installed on the main drainage tank 1 and connected to the monitoring module, is used to provide feedback on the water flow velocity measured by the monitoring module; wherein
[0045] The monitoring module includes:
[0046] Rotating blade 10 is movably installed in the main drainage box 1 via rotating shaft 11. Each blade of the rotating blade 10 has a cavity. A flow channel 15 communicating with the cavity is provided in the rotating blade 10. An exhaust hole 14 is provided in the flow channel 15.
[0047] The counterweight 12 is movably mounted on each blade of the rotating blade 10; and
[0048] Piston 13 is movably disposed in the cavity and connected to the counterweight 12. Piston 13 is elastically connected to the inner wall of the cavity and connected to the feedback module.
[0049] In one specific embodiment, the feedback module includes:
[0050] Sleeve 16 is mounted on the main drainage box 1 and the sliding sleeve is mounted on one end of the rotating blade 10;
[0051] The exhaust pipe 22 is installed on the main drainage box 1 and is connected to the flow channel 15 through the sleeve 16;
[0052] Slider 23 is movably disposed within exhaust pipe 22; and
[0053] A monitoring unit is installed inside the exhaust pipe 22 and connected to the slider 23. The monitoring unit is connected to the slider 23 and electrically connected to the controller 21. The monitoring unit is used to monitor the position of the slider 23.
[0054] In another specific embodiment, the monitoring unit includes a conductive head 24 and a resistor strip 25. The conductive head 24 is movably disposed inside the exhaust pipe 22 and connected to the slider 23. The resistor strip 25 is disposed on the inner wall of the exhaust pipe 22 and located on the moving path of the conductive head 24. The resistor strip 25, the conductive head 24, and the controller 21 are electrically connected.
[0055] It should be noted that the monitoring unit in this embodiment is not limited to the above-mentioned combination of conductive head 24 and resistor strip 25. It can also be replaced by infrared ranging sensor or laser ranging sensor, which will not be listed here.
[0056] In practical applications, the main drainage box 1 and the auxiliary drainage box 2 are connected between the water pump and the water pipe. The water flow through the rotor 10 can drive the rotor 10 to rotate continuously. Under the action of centrifugal force, the counterweight can be moved towards the outer end of the rotor 10 blade, thereby driving the piston 13 to move in the cavity. Under the action of air pressure, the air in the exhaust pipe 22 can be drawn into the cavity, thereby driving the slider 23 and the conductive head 24 to move. The conductive head 24 can contact different positions on the resistor bar 25 according to the size of the water flow. The controller 21 can convert the resistance information into a flow rate value and feed it back to the operator. Thus, the operator can judge whether there is a blockage inside the water pump when it is working based on the flow rate value, without the need for the operator to disassemble the water pump for inspection, which improves the efficiency of water pump fault detection.
[0057] Please see Figures 1-5 In another preferred embodiment of this application, the feedback device further includes a cleaning module, which is disposed between the main drainage tank 1 and the auxiliary drainage tank 2 and connected to the monitoring module. When the monitoring module is working, it controls the cleaning module to work and cleans the filter screen 3.
[0058] In one specific embodiment, the cleaning module includes:
[0059] The sliding seat 4 is movably installed inside the main drainage box 1 and located on one side of the filter screen 3. The sliding seat 4 is provided with a backflow groove 5, which can change the direction of water flow.
[0060] The slide bar 7 is movably mounted on the main drainage box 1 and one end is connected to the sliding seat 4; and
[0061] An adjustment structure is installed between the monitoring module and the slide bar 7 to control the movement of the slide bar 7.
[0062] It should be noted that the backflow channel 5 is U-shaped.
[0063] In another specific embodiment, the adjustment structure includes:
[0064] A movable seat 8 is movably mounted on the main drainage box 1, and the movable seat 8 is movably connected to the other end of the push arm 6 and the slide rod 7.
[0065] Cylinder 9 is mounted on the main drainage box 1 and its movable end is connected to the movable seat 8;
[0066] Hollow pipe 17 is installed on drainage auxiliary box 2, and hollow pipe 17 is connected to cylinder 9;
[0067] Piston 16, movably disposed within hollow tube 17 and elastically connected to it; and
[0068] The drive disc 20 is movably mounted on the drainage auxiliary box 2 and coaxially connected to the rotating blade 10. The eccentric position of the drive disc 20 is movably connected to the drive arm 19 and the second piston 16.
[0069] It should be noted that this embodiment is not limited to the cylinder 9 mentioned above for adjusting the position of the moving seat 8. A linear motor, electric cylinder or hydraulic cylinder can also be used instead, as long as it can control the reciprocating motion of the moving seat 8. They will not be listed one by one here.
[0070] As the water output from the pump enters the main drainage tank 1 and the auxiliary drainage tank 2, it drives the vane 10 to rotate, which in turn drives the drive disc 20 to rotate synchronously. Under the action of the drive arm 19, it drives the second piston 16 to reciprocate along the hollow tube 17, thereby repeatedly squeezing the air in the hollow tube 17 into the cylinder 9 and driving the cylinder 9 to continuously extend and retract. This, in turn, drives the moving seat 8 to reciprocate relative to the main drainage tank 1. Under the action of the push arm 6, it drives the slide rod 7 and the sliding seat 4 to reciprocate on the main drainage tank 1, thereby adjusting the position of the sliding seat 4. Furthermore, when the water flows through the U-shaped countercurrent channel 5, it can change the direction of the water flow, thereby rinsing the filter screen 3 and preventing impurities in the water flow from clogging the filter holes. This achieves automatic cleaning of the filter screen 3, eliminating the need for staff to clean the filter screen 3 regularly. It also prevents impurities on the filter screen 3 from affecting the detection of water pump malfunctions.
[0071] How this application works:
[0072] The main drainage box 1 and the auxiliary drainage box 2 are connected between the water pump and the water pipe. The water flow through the rotor 10 can drive the rotor 10 to rotate continuously. Under the action of centrifugal force, the counterweight can be moved towards the outer end of the rotor 10 blade, thereby driving the piston 13 to move in the cavity. Under the action of air pressure, the air in the exhaust pipe 22 can be drawn into the cavity, thereby driving the slider 23 and the conductive head 24 to move. The conductive head 24 can contact different positions on the resistor bar 25 according to the water flow. The controller 21 can convert the resistance information into a flow rate value and feed it back to the operator. Thus, the operator can judge whether there is a blockage inside the water pump when it is working based on the flow rate value, without the need for the operator to disassemble the water pump for inspection, which improves the efficiency of water pump fault detection. As the water output from the pump enters the main drainage tank 1 and the auxiliary drainage tank 2, it drives the vane 10 to rotate, which in turn drives the drive disc 20 to rotate synchronously. Under the action of the drive arm 19, it drives the second piston 16 to reciprocate along the hollow tube 17, thereby repeatedly squeezing the air in the hollow tube 17 into the cylinder 9 and driving the cylinder 9 to continuously extend and retract. This, in turn, drives the moving seat 8 to reciprocate relative to the main drainage tank 1. Under the action of the push arm 6, it drives the slide rod 7 and the sliding seat 4 to reciprocate on the main drainage tank 1, thereby adjusting the position of the sliding seat 4. Furthermore, when the water flows through the U-shaped countercurrent channel 5, it can change the direction of the water flow, thereby rinsing the filter screen 3 and preventing impurities in the water flow from clogging the filter holes. This achieves automatic cleaning of the filter screen 3, eliminating the need for staff to clean the filter screen 3 regularly. It also prevents impurities on the filter screen 3 from affecting the detection of water pump malfunctions.
