Description

TECHNICAL FIELD

[0001] The present application relates to the field of water pumps, in particular to a water pump with real-time monitoring function. BACKGROUND

[0002] Water pumps, as a common fluid conveying device, play a crucial role in industrial production, agricultural irrigation, and daily life water supply. The traditional water pump is mainly composed of a pump shell, a pump body, and a motor, and its core function is to realize efficient transmission of liquid by driving the pump body with the motor.

[0003] In actual application, in order to ensure that the water pump can work continuously and stably, various measures are usually taken to monitor and maintain the equipment. For example, regularly check the working state of the motor, manually detect the water flow pressure in the pipeline, or install a simple alarm device to remind the operator to pay attention to abnormal conditions. In addition, some schemes use basic pressure gauges or flow meters for preliminary data collection, and combine manual judgment to decide whether maintenance is needed. These methods can alleviate the problem to some extent, but due to the lack of real-time data feedback mechanism, often lead to untimely fault discovery, thereby affecting the normal operation of the overall system.

[0004] Although the above methods can cope with common problems in water pump operation within a certain range, there are still obvious deficiencies when facing complex working conditions. Especially when the motor fails and is not quickly detected, it may cause the water pump to continue to operate, thereby causing greater safety hazards such as excessive wear, energy waste, and even system paralysis. Therefore, at present, there is an urgent need for a method that can effectively monitor the operating parameters of the water pump and combine with external control, so as to quickly identify potential risks and implement shutdown protection, thereby improving the reliability and safety of the entire system. SUMMARY

[0005] In order to quickly identify potential risks and implement shutdown protection, improve the reliability and safety of the water pump, the present application provides a water pump with real-time monitoring function.

[0006] The water pump with real-time monitoring function provided by the present application adopts the following technical scheme:

[0007] The water pump with real-time monitoring function comprises a pump shell, a pressure sensor, a pump body, a motor and a remote terminal; the pressure sensor and the pump body are arranged in the interior of the pump shell, the pressure sensor is in communication connection with the remote terminal, the pressure sensor is used for collecting water pressure signals and sending the water pressure signals to the remote terminal; the vibration monitoring mechanism is arranged in the interior of the pump shell, the vibration monitoring mechanism is used for monitoring the bearing and impeller state of the pump body, and the vibration monitoring mechanism is in communication connection with the remote terminal; the motor is used for driving the pump body to rotate, the motor is in communication connection with the remote terminal, and the remote terminal remotely controls the start and stop and power of the motor.

[0008] By adopting the above technical scheme, the pressure sensor, the vibration monitoring mechanism and the remote terminal are used to realize real-time monitoring and control of the running state of the water pump. Specifically, the power of the motor is controlled by the remote terminal, the water pressure signals are collected by the pressure sensor and sent to the remote terminal, the remote terminal analyzes the water pressure signals and compares the motor power to ensure that the water pressure matches the motor power. Once an abnormal condition is detected, such as a significant difference between the water pressure and the motor power, the remote terminal can stop the motor operation in time to avoid unstable water supply caused by motor failure, thereby improving the reliability and safety of the water pump system. At the same time, the vibration monitoring mechanism is used to detect the bearing and impeller state of the pump body in real time. If the bearing and impeller fail, the remote terminal can stop the motor for maintenance, so that maintenance personnel can quickly arrive at the installation position of the water pump for maintenance, thereby reducing the risk of safety accidents.

[0009] Optionally, a protective shell is arranged between the pump shell and the motor, one end of the protective shell is detachably connected to the motor, and the other end is connected to the pump shell; the motor has a machine shell; a first plug-in part is arranged on the end face of the protective shell close to the motor, and a first plug-in cavity for inserting the first plug-in part is formed in the end face of the machine shell close to the protective shell; a first conductive point and a second conductive point are arranged on the cavity wall of the first plug-in cavity, and a conductive part is arranged on the first plug-in part; when the protective shell is connected to the motor, the first conductive point and the second conductive point are in electrical communication, and when an external power source is connected, the motor starts.

[0010] By adopting the above technical scheme, the motor is ensured to start normally when the protective shell is connected to the motor. However, when the staff is repairing the water pump and the protective shell is removed, the first conductive point and the second conductive point cannot realize electrical communication due to the misplacement of the conductive part, thereby forcibly cutting off the power of the motor from the physical layer. This design effectively prevents the situation that someone accidentally or intentionally restarts the water pump during the repair process, reduces the potential safety hazards, and at the same time ensures the personal safety of the repair personnel and the smooth maintenance of the equipment.

[0011] Optionally, the protective shell is provided with a second plug-in part near the end face of the shell, and the shell is provided with a second plug-in cavity near the end face of the protective shell, which is used for plug-in of the second plug-in part; the second plug-in part is provided in plurality, and the plurality of second plug-in parts are arranged at intervals around the central axis of the protective shell, and the second plug-in cavity is correspondingly provided with plurality.

[0012] By adopting the above technical scheme, on the one hand, the cooperation of the second plug-in part and the second plug-in cavity enables the protective shell to be accurately aligned during installation, avoiding poor electrical connection or mechanical instability caused by positional deviation. On the other hand, in the case of being provided with the first plug-in cavity and the first plug-in part, the design of the plurality of second plug-in parts arranged at intervals around the central axis further improves the uniformity and reliability of the connection, ensuring that the communication connection and structural support between the protective shell and the motor are more stable.

[0013] Optionally, the first plug-in cavity is provided with a first spring, one end of the first spring is connected to the end face of the first plug-in cavity, and the other end is used for abutting the end of the first plug-in part; the second plug-in cavity is provided with a second spring, one end of the second spring is connected to the end face of the second plug-in cavity, and the other end is used for abutting the end of the second plug-in part; when the protective shell is connected to the motor, the first spring and the second spring are both in a compressed state.

[0014] By adopting the above technical scheme, since the first spring is arranged in the first plug-in cavity, and one end is connected to the end face of the first plug-in cavity, and the other end abuts the end of the first plug-in part; at the same time, the second spring is arranged in the second plug-in cavity, one end is connected to the end face of the second plug-in cavity, and the other end abuts the end of the second plug-in part. Therefore, when the protective shell starts to separate from the motor, the first spring and the second spring, which are originally in a compressed state, can release the stored energy and generate an outward thrust. This thrust makes the protective shell be smoothly pushed away from the shell, effectively preventing the protective shell from reinserting the shell due to accidental sliding. Thus, it is ensured that the conductive part will not be connected to the first conductive point and the second conductive point again, cutting off the circuit loop of the motor, further improving the safety of operation, and reducing the risk of misoperation.

[0015] Optionally, the first connecting edge is provided around the periphery of the end of the protective shell close to the casing, and the second connecting edge is provided around the periphery of the end of the casing close to the protective shell; the first connecting edge is provided with three first threaded cavities, which are arranged at equal intervals around the central axis of the casing, and the first threaded cavities are threadedly connected with first bolts; the second connecting edge is provided with a first through hole, which is used for the first bolts to pass through; the first connecting edge is provided with a spring cavity between every two first threaded cavities, the two ends of the spring cavity are respectively communicated with the two adjacent first threaded cavities, the port diameter of the spring cavity is smaller than the inner diameter of the spring cavity; the spring cavity is provided with a limiting spring and two balls, the limiting spring is located between the two balls, and the diameter of the ball is smaller than the port diameter of the spring cavity; when one ball in one spring cavity abuts against the port wall of the spring cavity and the other ball is located in the spring cavity, the limiting spring is in a compressed state; the first bolt is provided with two limiting grooves at the end away from the nut, and the groove walls of the two limiting grooves are respectively used for the two adjacent balls to abut against.

[0016] By adopting the above technical scheme, when the protective shell is not detached from the casing, the first bolt is firmly threadedly connected in the first threaded cavity, at this time, the two balls in each spring cavity are completely located in the spring cavity, and the limiting spring is in a compressed state. When the first first bolt is started to be disassembled, as the first bolt is gradually screwed out, when the limiting groove thereon moves to the position corresponding to the spring cavity, the limiting spring originally under compression releases the elastic force, and pushes the ball into the limiting groove of the first bolt. This process will produce a clear impact sound, and the force required to continue to screw the first bolt will increase, thereby reminding the staff of the current operation progress and prompting to switch to the next first bolt for disassembly. According to this way, each first bolt is disassembled in turn, when the last (i.e. the third) first bolt is disassembled, the limiting spring in all spring cavities reaches the maximum extension and the minimum deformation. At the same time, due to the interaction between the previous components, the first spring and the second spring have accumulated enough elastic potential energy, and the protective shell is partially pried away from the casing by a certain distance, at this time, the conductive part inside the protective shell is completely separated from the first conductive point and the second conductive point on the casing, the circuit connection is successfully cut off, and the protective shell and the casing still have a certain connection, thereby ensuring that the motor is always in a power-off state during the subsequent complete disassembly process, further reducing the safety hazard.

[0017] In addition, if a first bolt is loose, when the first bolt is rotated to the position where the ball enters the groove, the insertion fit between the ball and the groove can also limit the loose first bolt to a certain extent, preventing the first bolt from continuing to loosen, and further improving the safety of the water pump.

[0018] Optionally, the second connecting edge is slidably connected to the protective shell along a length direction of the protective shell; the protective shell is provided with an abutting edge near one end of the motor, the second connecting edge is provided with an abutting groove for accommodating the abutting edge near a surface of the motor, and a groove bottom of the abutting groove is used for abutting the abutting edge.

[0019] By adopting the above technical scheme, the second connecting edge can slide relative to the protective shell, so that the second connecting edge can be directly disassembled without moving another component in advance, and the motor is forced to be powered off in the process of disassembling the second connecting edge, thereby improving the disassembly convenience and safety of the water pump.

[0020] Optionally, the third connecting edge and the second connecting edge are both provided with a plurality of second through holes, a second bolt is arranged in the second through hole, and the second bolt is threadedly connected with a limiting nut.

[0021] By adopting the above technical scheme, the connection strength between the two is effectively enhanced, and loosening caused by external vibration or impact is prevented.

[0022] Optionally, the protective shell and the pump shell are detachably connected.

[0023] Optionally, the first connecting edge includes a fixed part and a movable part, the fixed part is fixedly connected to the machine shell, the movable part is detachably connected with the fixed part, and the spring cavity is arranged in the movable part.

[0024] By adopting the above technical scheme, during maintenance, the first bolt is screwed to abut the ball against the groove, then the connection between the protective shell and the pump shell is released, and then the protective shell can be directly disassembled from the machine shell by releasing the connection between the movable part and the fixed part, thereby improving the disassembly convenience.

[0025] Optionally, a plug-in groove is arranged on a surface of the fixed part facing the movable part, a first abutting piece is arranged in the plug-in groove, the plug-in groove has a plug-in interval between the first abutting piece and a groove bottom of the plug-in groove, a plug-in protrusion is arranged on a surface of the movable part facing the fixed part, the plug-in protrusion is provided with a second abutting piece, the plug-in interval is used for inserting the second abutting piece, and the first abutting piece is used for abutting the second abutting piece.

[0026] By adopting the technical scheme, when the movable part is connected to the fixed part, the plug-in convex is inserted into the plug-in slot first, then the movable part is rotated relative to the fixed part, the second abutting piece is inserted into the plug-in interval, and thus the transverse limiting of the fixed part on the movable part is completed; when the water pump is disassembled, after the first bolt is screwed into the movable part, the movable part is reversely rotated relative to the fixed part, the second abutting piece is pulled out of the plug-in interval, then the plug-in convex is pulled out of the plug-in slot, and thus the disassembly of the movable part and the fixed part is completed, which is simple in structure and convenient to operate.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. By arranging a pressure sensor inside the pump shell and cooperating with a remote terminal to monitor water pressure and motor state in real time, it can accurately determine whether they match, and timely find abnormal conditions to avoid unstable water supply problems caused by motor failure; at the same time, the vibration monitoring mechanism is used to detect the bearing and impeller state of the pump body in real time, if the bearing and impeller fail, the motor is stopped by the remote terminal, and the maintenance personnel go to the installation position of the water pump for maintenance, which reduces the risk of safety accidents of the water pump.

[0065] When the maintenance personnel disassemble and maintain the water pump, the second bolt 482 is first unscrewed, and the limiting between the third connecting edge 48 and the second connecting edge 63 is contacted; then one of the three first bolts 47 is screwed, and as the first bolt 47 is gradually unscrewed, when the groove 471 of the first bolt 47 reaches the spring cavity 464 adjacent to it, the limiting springs 465 in the two spring cavities 464 push the ball 466 out. At this time, when the maintenance personnel hear the collision sound of the ball 466 and the first bolt 47 and feel that the resistance is obviously increased, the second second bolt 482 is switched to be screwed, and when the second second bolt 482 is screwed to hear the collision sound of the ball 466 and the first bolt 47 and feel that the resistance is obviously increased, the last (i.e. the third) first bolt 47 is switched to be screwed.

[0066] When the third first bolt 47 is screwed to the ball 466 into the groove 471, the first spring 421 and the second spring 451 push the second connecting edge 63 to move away from the motor 4, so that the conductive part 62 is dislocated with the first conductive point 43 and the second conductive point 44, thereby breaking the internal loop of the motor 4 and forcibly physically cutting off the power of the motor 4.

[0067] Then, the movable part 462 and the second connecting side 63 are rotated relative to the fixed part 461, so that the second abutting part 4622 is out of the insertion interval 4613; then the insertion protrusion 4621 is continuously pulled out of the insertion slot 4611, and then the subsequent disassembly work can be continued.

[0068] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
