Description

Technical Field

[0001] This application relates to the field of water pumps, and in particular to a water pump with a real-time monitoring function. Background Art

[0002] As a common fluid transportation device, water pumps play a crucial role in industrial production, agricultural irrigation, and daily water supply. Traditionally, a water pump mainly consists of a pump casing, a pump body, and an electric motor, and its core function is to efficiently transport liquids by driving the pump body with the electric motor.

[0003] In practical applications, to ensure the continuous and stable operation of the water pump, various measures are usually taken to monitor and maintain the equipment. For example, regularly checking the working status of the electric motor, manually detecting the water flow pressure in the pipeline, or installing a simple alarm device to alert the operator of abnormal situations. In addition, some solutions use basic pressure gauges or flow meters for preliminary data collection and combine manual judgment to decide whether maintenance is required. Although these methods can alleviate problems to a certain extent, due to the lack of a real-time data feedback mechanism, faults are often not detected in a timely manner, thus affecting the normal operation of the overall system.

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

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

[0006] The water pump with a real-time monitoring function provided by this application adopts the following technical solutions: A water pump with a real-time monitoring function includes a pump housing, a pressure sensor, a pump body, an electric motor, and a remote terminal. The pressure sensor and the pump body are both arranged inside the pump housing. The pressure sensor is communicatively connected to the remote terminal and is used to collect water pressure signals and send the water pressure signals to the remote terminal. The vibration monitoring mechanism is arranged inside the pump housing and is used to monitor the states of the bearings and impellers of the pump body. The vibration monitoring mechanism is communicatively connected to the remote terminal. The electric motor is used to drive the pump body to rotate. The electric motor is communicatively connected to the remote terminal, and the remote terminal remotely controls the start / stop and power of the electric motor.

[0007] By adopting the above technical solution, the real-time monitoring and control of the operating state of the water pump are realized by using the pressure sensor, the vibration monitoring mechanism, and the remote terminal. Specifically, the power of the electric motor is controlled by the remote terminal. The water pressure signal is collected by the pressure sensor and sent to the remote terminal. The remote terminal analyzes the water pressure signal and compares it with the power of the electric motor to ensure the matching of the water pressure and the power of the electric motor. Once an abnormal situation is detected, such as an obvious difference between the water pressure and the power of the electric motor, the remote terminal can stop the operation of the electric motor in time to avoid the problem of 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 states of the bearings and impellers of the pump body in real time. If a failure occurs in the bearings and impellers, the electric motor can be stopped by the remote terminal, and the maintenance personnel can rush to the installation location of the water pump for maintenance in time, reducing the risk of safety accidents.

[0008] Optionally, a protective housing is arranged between the pump housing and the electric motor. One end of the protective housing is detachably connected to the electric motor, and the other end is connected to the pump housing. The electric motor has a motor housing. A first plug-in member is arranged on the end face of the protective housing close to the electric motor, and a first plug-in cavity for inserting the first plug-in member is formed on the end face of the motor housing close to the protective housing. The cavity wall of the first plug-in cavity is provided with a first conductive point and a second conductive point, and the first plug-in member is provided with a conductive member. When the protective housing is connected to the electric motor, the first conductive point and the second conductive point are electrically connected, and when an external power supply is connected, the electric motor starts.

[0009] By adopting the above technical solution, it is ensured that the electric motor starts normally when the protective housing is connected to the electric motor. During the process of the staff overhauling the water pump and removing the protective housing, due to the misalignment of the conductive member, the first conductive point and the second conductive point cannot be electrically connected, thus forcibly cutting off the power supply of the electric motor physically. This design effectively prevents the situation that someone accidentally or deliberately restarts the water pump through the remote terminal during the overhaul process, reduces potential safety hazards, and at the same time ensures the personal safety of the maintenance personnel and the smooth progress of equipment maintenance.

[0010] Optionally, a second plug-in member is provided on the end face of the protective case close to the machine case, and a second plug-in cavity is formed on the end face of the machine case close to the protective case. The second plug-in cavity is used for the second plug-in member to be inserted; there are a plurality of second plug-in members, and the plurality of second plug-in members are arranged at intervals around the central axis of the protective case, and correspondingly, there are a plurality of second plug-in cavities.

[0011] By adopting the above technical solutions, on the one hand, the cooperation between the second plug-in member and the second plug-in cavity enables the protective case to be accurately aligned during the installation process, avoiding problems such as poor electrical connection or mechanical instability caused by position deviation. On the other hand, in the case where there are a first plug-in cavity and a first plug-in member, the design of arranging a plurality of second plug-in members 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 case and the motor are more stable.

[0012] Optionally, a first spring is provided in the first plug-in cavity. One end of the first spring is connected to the end face of the first plug-in cavity, and the other end is for the end of the first plug-in member to abut against; a second spring is provided in the second plug-in cavity. One end of the second spring is connected to the end face of the second plug-in cavity, and the other end is for the end of the second plug-in member to abut against; when the protective case is connected to the motor, both the first spring and the second spring are in a compressed state.

[0013] By adopting the above technical solutions, since the first spring is provided in the first plug-in cavity, with one end connected to the end face of the first plug-in cavity and the other end abutting against the end of the first plug-in member; at the same time, the second spring is provided in the second plug-in cavity, with one end connected to the end face of the second plug-in cavity and the other end abutting against the end of the second plug-in member. Therefore, when the protective case starts to separate from the motor, the first spring and the second spring that were originally in a compressed state can release the stored energy and generate an outward thrust. This thrust causes the protective case to be smoothly pushed away from the machine case, effectively preventing the situation where the protective case accidentally slides back and re-inserts into the machine case. Thus, it ensures that the conductive member will not connect the first conductive point and the second conductive point again, cutting off the circuit loop of the motor, further improving the operation safety and reducing the risk of mis-start.

[0014] Optionally, a first connecting edge is circumferentially arranged around the circumference of the end of the casing close to the protective shell, and a second connecting edge is circumferentially arranged around the circumference of the end of the protective shell close to the casing; three first threaded cavities are provided in the first connecting edge, and the three first threaded cavities are arranged at equal intervals around the central axis of the casing. The first threaded cavity is threadedly connected with a first bolt; a first through hole is formed through the second connecting edge for the screw rod of the first bolt to pass through; a spring cavity is formed between every two of the first threaded cavities in the first connecting edge, and both ends of the spring cavity are respectively communicated with the adjacent two first threaded cavities, and the port diameter of the spring cavity is smaller than the inner diameter of the spring cavity; a limiting spring is arranged in the spring cavity, and two balls are arranged in the spring cavity. 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 of the balls in a spring cavity abuts against the port wall of the spring cavity and the other ball is completely located in the spring cavity, the limiting spring is in a compressed state; two limiting grooves are formed at the end of the first bolt far from its nut, and the groove walls of the two limiting grooves are respectively used for abutting against the adjacent two balls.

[0015] By adopting the above technical solution, when the protective shell is not removed 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 starting to disassemble the first first bolt, as the first bolt is gradually screwed out, when the limiting groove on it moves to a position corresponding to the spring cavity, the originally compressed limiting spring releases elastic force and pushes the ball into the limiting groove of the first bolt. This process will produce an obvious impact sound and increase the force required to continue screwing the first bolt, thereby reminding the staff of the current operation progress and prompting to switch to the next first bolt for disassembly. Disassemble each first bolt in this way. When disassembling the last (i.e., the third) first bolt, the limiting springs in all the spring cavities reach the maximum degree of extension and the minimum deformation. At the same time, due to the mutual interaction of the previous components, the first spring and the second spring have accumulated sufficient elastic potential energy to push the protective shell away from the casing by a certain distance. At this time, the conductive parts inside the protective shell are completely separated from the first conductive point and the second conductive point on the casing, successfully cutting off the circuit connection, and there is still a certain connection between the protective shell and the casing, so as to ensure that the motor is always powered off during the subsequent complete disassembly process, further reducing potential safety hazards.

[0016] In addition, if a certain first bolt becomes loose, when the first bolt rotates until the ball enters the groove, the plug-in fit between the ball and the groove can also form a certain limit on the loose first bolt to prevent the first bolt from loosening further, further improving the safety of the water pump.

[0017] Optionally, the second connecting edge is slidably connected to the protective housing along the length direction of the protective housing; an abutting edge is provided at one end of the protective housing close to the motor, and an abutting groove for accommodating the abutting edge is formed on the surface of the second connecting edge close to the motor, and the bottom of the abutting groove is for the abutting edge to abut against.

[0018] By adopting the above technical solution, the second connecting edge can slide relative to the protective housing, so that during the disassembly process, it is not necessary to move other components first, and the second connecting edge can be directly disassembled. Furthermore, during the disassembly of the second connecting edge, the motor can be forced to power off, improving the disassembly convenience and safety of the water pump.

[0019] Optionally, a third connecting edge is circumferentially arranged around the outer periphery of the first connecting edge of the housing, and a plurality of second through holes are formed in both the third connecting edge and the second connecting edge. A second bolt is passed through the second through hole, and the second bolt is threadedly connected with a limit nut; the plurality of second through holes are arranged at intervals around the central axis of the housing.

[0020] By adopting the above technical solution, the connection strength between the two is effectively enhanced, preventing loosening caused by external vibration or impact.

[0021] Optionally, the protective housing is detachably connected to the pump housing.

[0022] Optionally, the first connecting edge includes a fixed part and a movable part. The fixed part is fixedly connected to the housing, and the movable part is detachably connected to the fixed part; the spring cavity is arranged in the movable part.

[0023] By adopting the above technical solution, during maintenance, first turn the first bolt until the ball abuts against the groove, then disconnect the connection between the protective housing and the pump housing, and then the protective housing can be directly removed from the housing by disconnecting the connection between the movable part and the fixed part, improving the disassembly convenience.

[0024] Optionally, a plugging groove is formed on the surface of the fixed part facing the movable part, a first abutting member is arranged in the plugging groove, and there is a plugging interval between the first abutting member and the bottom of the plugging groove; a plugging protrusion is arranged on the surface of the movable part facing the fixed part, a second abutting member is arranged on the plugging protrusion, the plugging interval is for the second abutting member to be inserted, and the first abutting member is for the second abutting member to abut against.

[0025] By adopting the above technical solution, when connecting the movable part to the fixed part, first insert the insertion protrusion into the insertion groove, and then rotate the movable part relative to the fixed part so that the second abutting part is inserted into the insertion interval, thereby completing the lateral limit of the movable part by the fixed part; when disassembling the water pump, after screwing the first bolt into the movable part, rotate the movable part in the reverse direction relative to the fixed part so that the second abutting part disengages from the insertion interval, and then pull out the insertion protrusion from the insertion groove, and the disassembly of the movable part and the fixed part can be completed. The structure is simple and convenient to operate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By arranging a pressure sensor inside the pump housing and cooperating with a remote terminal to monitor the water pressure and the motor state in real time, it is possible to accurately judge whether the two match, timely detect abnormal situations, and avoid the problem of unstable water supply caused by motor failures; at the same time, the vibration monitoring mechanism is used to detect the bearing and impeller states of the pump body in real time. If the bearing and impeller fail, the motor is shut down through the remote terminal, and the maintenance personnel can go to the installation location of the water pump for maintenance, reducing the risk of safety accidents of the water pump.

[0027] 2. By arranging a mutually cooperating first insertion cavity and a first insertion part, and arranging a first conductive part and a second conductive part on the cavity wall of the first insertion cavity, and arranging a conductive part on the first insertion part, after the protective shell is separated from the machine shell, the motor is in a physically powered-off state, improving the safety of maintenance; 3. By arranging a spring cavity on the first connection edge and arranging a limiting spring and a ball in the spring cavity, during the process of screwing the first bolt, when the groove reaches the corresponding position, the ball is pushed into the groove by the limiting spring, achieving the effect of reminding the maintenance personnel and being able to perform a certain limit, improving the safety of maintenance.

[0044] The motor 4 is used to drive the pump body 2 to rotate. The motor 4 is communicatively connected to the remote terminal 5, and the remote terminal 5 remotely controls the start-stop and operating power of the motor 4. The pressure sensor 3 can accurately collect water pressure signals and send the water pressure signals to the remote terminal 5 for analysis to ensure that the water pressure matches the power of the motor 4.

At the same time, the vibration monitoring mechanism is used to detect the states of the bearings and impellers of the pump body 2 in real time. If the bearings and impellers fail, the motor 4 is shut down through the remote terminal 5, and the maintenance personnel can go to the installation location of the water pump for maintenance.

One end of the second spring 451 is connected to the end face of the second insertion cavity 45, and the other end is for the end of the second plug-in member 67 to abut against. When the protective shell 6 is connected to the motor 4, both the first spring 421 and the second spring 451 are in a compressed state.

[0048] To ensure the stability of the first spring 421, a guide rod 422 is inserted through the first spring 421, and a guide cavity 611 for the guide rod 422 to pass through is provided at the end of the first plug-in member 61.

[0052] Refer to Figure 7 and Figure 8 , in this embodiment, the specific structure of the detachable connection between the movable part 462 and the fixed part 461 is as follows: a plug-in slot 4611 is opened on the surface of the fixed part 461 facing the movable part 462. The plug-in slot 4611 is arranged in an arc shape around the central axis of the housing 41. A first abutting member 4612 is arranged in the plug-in slot 4611, and there is a plug-in interval 4613 between the first abutting member 4612 and the bottom of the plug-in slot 4611. A plug-in protrusion 4621 is arranged on the surface of the movable part 462 facing the fixed part 461. A second abutting member 4622 is arranged on the plug-in protrusion 4621. The plug-in interval 4613 is for the second abutting member 4622 to be inserted, and the first abutting member 4612 is for the second abutting member 4622 to abut against.

[0053] In other embodiments, the movable part 462 can also be detachably connected to the fixed part 461 by means of snap connection or threaded connection, as long as the lateral limit of the movable part 462 can be achieved.

[0054] Refer to Figure 6, a plurality of sliding blocks 631 are fixedly connected to the inner ring wall of the second connecting edge 63, and the plurality of sliding blocks 631 are arranged at intervals around the central axis of the second connecting edge 63. A sliding groove 64 for the sliding block 631 to slide is formed in the outer wall of the protective shell 6 along its own length direction, and a plurality of sliding grooves 64 are correspondingly formed.

[0055] A rotating groove 65 is further formed in the outer wall of the protective shell 6, and the rotating groove 65 is arranged to surround the protective shell 6 in the circumferential direction and communicates with the plurality of sliding grooves 64. The rotating groove 65 is used for the sliding block 631 to slide. When the first spring 421 and the second spring 451 push the second connecting edge 63 out of the casing 41, the sliding block 631 is located in the rotating groove 65.

[0056] Refer to Figure 3 and Figure 9 , an abutting edge 66 is provided at one end of the protective shell 6 close to the motor 4, and an abutting groove 68 for accommodating the abutting edge 66 is formed in the surface of the second connecting edge 63 close to the motor 4. The bottom of the abutting groove 68 is for the abutting edge 66 to abut against.

[0057] Refer to Figure 3 and Figure 10 , three first threaded cavities 463 are formed in the first connecting edge 46, and the three first threaded cavities 463 are arranged at equal intervals around the central axis of the casing 41. A first bolt 47 is threadedly connected to the first threaded cavity 463. A first through hole (not marked in the figure) is formed through the second connecting edge 63, and the first through hole is for the screw rod of the first bolt 47 to pass through.

[0058] Refer to Figure 10 , Figure 11 and Figure 12 , a spring cavity 464 is formed in the first connecting edge 46 between every two first threaded cavities 463, and the spring cavity 464 is formed in the movable part 462. The two ends of the spring cavity 464 are respectively communicated with the adjacent two first threaded cavities 463, and the port diameter of the spring cavity 464 is smaller than the inner diameter of the spring cavity 464. A limiting spring 465 is arranged in the spring cavity 464, and two balls 466 are arranged in the spring cavity 464. The limiting spring 465 is located between the two balls 466, and the diameter of the ball 466 is smaller than the port diameter of the spring cavity 464. When one ball 466 in a spring cavity 464 abuts against the port wall of the spring cavity 464 and the other ball 466 is entirely located in the spring cavity 464, the limiting spring 465 is in a compressed state. Two limiting grooves 471 are formed at the end of the first bolt 47 far from its nut, and the groove walls of the two limiting grooves 471 are respectively for the adjacent two balls 466 to abut against.

[0059] Further, a second plug-in member 67 is provided on the end face of the protective shell 6 close to the housing 41, and a second plug-in cavity 45 is formed on the end face of the housing 41 close to the protective shell 6. The second plug-in cavity 45 is used for the second plug-in member 67 to be inserted. There are a plurality of second plug-in members 67, and the plurality of second plug-in members 67 are arranged at intervals around the central axis of the protective shell 6. Correspondingly, there are a plurality of second plug-in cavities 45, so as to improve the connection stability between the protective shell 6 and the housing 41 when the first plug-in cavity 42 and the first plug-in member 61 are provided.

[0060] Further, a third connecting edge 48 is circumferentially arranged around the outer periphery of the first connecting edge 46 of the housing 41. A plurality of second through holes (not marked in the figure) are formed in both the third connecting edge 48 and the second connecting edge 63. A second bolt 482 is passed through the second through holes, and a limit nut 483 is threadedly connected to the second bolt 482. The plurality of second through holes are arranged at intervals around the central axis of the housing 41. In order to utilize the cooperation of the second bolt 482 and the limit nut 483 to strengthen the connection stability between the protective shell 6 and the housing 41.

[0061] The implementation principle of a water pump with a real-time monitoring function in an embodiment of the present application is as follows: when the water pump is working normally, the staff adjusts the power of the motor 4 through the remote terminal 5, so as to adjust the water pressure. The pressure sensor 3 monitors the water pressure in real time, obtains the water pressure signal, and sends the water pressure signal to the remote terminal 5. When the remote terminal 5 receives the water pressure signal, it analyzes whether the water pressure matches the power of the motor 4. If the difference is large, the motor 4 is remotely shut down, and the maintenance personnel are notified to rush to the site for maintenance.

[0062] When the maintenance personnel disassemble the water pump for maintenance, first unscrew the second bolt 482 to release the limit between the third connecting edge 48 and the second connecting edge 63; then turn one of the three first bolts 47. As the first bolt 47 is gradually unscrewed, when the groove 471 of the first bolt 47 reaches the adjacent spring cavity 464, the limit springs 465 in these two spring cavities 464 push out the ball 466. 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 becomes significantly larger, switch to the second second bolt 482 to turn. When turning until hearing the collision sound of the ball 466 and the first bolt 47 and feeling that the resistance becomes significantly larger, switch to the last (i.e., the third) first bolt 47 to turn.

[0063] When the third first bolt 47 is turned until the ball 466 enters 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 member 62 is misaligned with the first conductive point 43 and the second conductive point 44, thereby breaking the internal circuit of the motor 4 and forcibly physically powering off the motor 4.

[0064] Subsequently, rotate the movable part 462 and the second connecting edge 63 relative to the fixed part 461 to disengage the second abutting member 4622 from the insertion interval 4613; then continue to withdraw the insertion protrusion 4621 from the insertion groove 4611, and then continue with the subsequent disassembly work.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly.
