Description

Technical Field

[0001] This utility model relates to water pumps, and more particularly to a submersible pump with real-time monitoring and intelligent control. Background Technology

[0002] A submersible pump is a type of pump specifically designed for underwater operation, capable of operating efficiently in a fully submerged environment. This type of pump typically consists of key components such as a motor, pump body, and sealing devices. The motor drives the impeller to rotate, thereby achieving the extraction and transportation of water. Currently, there is a need for a submersible pump for use at the bottom of a pool to assist in water replacement.

[0003] Chinese patent CN216642472U discloses a cutting submersible pump, including a pump body. The bottom of the pump body has a bottom inlet and a side inlet, and the side of the pump body has an outlet connected to its inner cavity. The upper part of the pump body's inner cavity has a motor, and a partition is provided below the motor. The output end of the motor has a rotating shaft, and the middle part of the rotating shaft has blades corresponding to the position of the outlet. Below the bottom inlet, there is a mounting block with a cutting opening that communicates with the bottom inlet to achieve a cutting effect, thereby improving sewage discharge efficiency.

[0004] The aforementioned patents still have shortcomings. The submersible pumps cannot achieve real-time monitoring and intelligent control of their operating status under complex working conditions, which makes them prone to failure during operation and unable to provide timely warnings, affecting their stability and service life. Furthermore, protective measures cannot be taken in a timely manner when a failure occurs. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a submersible pump with real-time monitoring and intelligent control, which has the functions of real-time monitoring and intelligent control.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a submersible pump with real-time monitoring and intelligent control, including a pump body, an inlet at the bottom of the pump body, an outlet at the side end, a drive motor inside the pump body, blades on the output shaft of the drive motor, a control box at the side end of the drive motor, a PLC board inside the control box, a pressure sensor at the outlet, the pressure sensor being electrically connected to the input module of the PLC board, a float assembly at the side end of the control box, the float assembly being electrically connected to the input module of the PLC board, and the drive motor being electrically connected to the output module of the PLC board.

[0007] Preferably, a water outlet pipe is provided at the water outlet of the pump body, and the power cord of the pump body and the PLC board extends from the control box, and the power cord is tied and fixed to the water outlet pipe.

[0008] Preferably, the control box has a float trough on its side, and the float assembly includes a sliding float, a micro switch one, and a micro switch two. The micro switch one and the micro switch two are respectively disposed on the upper and lower sides of the float trough. The sliding float has an air chamber on its inner side and is slidably disposed in the float trough. The sliding float floats with the water level.

[0009] Preferably, the bottom of the pump body is also provided with a mounting base, and a filter disc is provided between the mounting base and the pump body. The filter disc is basin-shaped and has a ring of filter holes on its side wall.

[0010] Preferably, the pump body is further provided with a cutting component, which is fixedly installed at the bottom of the impeller, and the cutting component cooperates with the filter disc to complete the cutting.

[0011] Preferably, the cutting assembly includes a connecting rod and a plurality of cutting blades. The connecting rod is fixed to the output end of the drive motor, and the cutting blades are disposed at the bottom of the connecting rod and abut against the inner wall of the filter disc.

[0012] Preferably, a support ring is provided at the bottom of the mounting base, and an installation ring is also provided at the bottom of the water tank. The support ring is located inside the installation ring, and a fixing block can be detachably provided on the installation ring. The fixing block is used to press down the support ring and fix the pump body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The PLC board analyzes and processes the data collected by the pressure sensor and float assembly. When the water level changes or the pressure is abnormal, the float assembly triggers a micro switch, which transmits a signal to the PLC board. The PLC board then controls the start and stop of the drive motor according to a preset program, realizing real-time monitoring and intelligent control of the submersible pump's operating status, thus improving the stability and reliability of the submersible pump.

[0015] 2. By setting up a filter disc, large particles of impurities can be effectively prevented from entering the pump body, avoiding the problem of submersible pump clogging. At the same time, the cooperation between the cutting component and the filter disc can cut small particles of impurities that enter the pump body, further improving the sewage discharge efficiency of the submersible pump;

[0016] 3. The combination of mounting base, support ring, mounting ring and fixing block makes the installation and disassembly of submersible pump more convenient and quick, while ensuring the stability of submersible pump during operation and the stable operation of float assembly.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0022] A submersible pump with real-time monitoring and intelligent control includes a pump body 1, an inlet 2 at the bottom of the pump body 1, and an outlet 3 at the side. A drive motor 4 is also installed inside the pump body 1. The output shaft of the drive motor 4 has blades 5 for generating water flow dynamics. A control box 6 is also installed on the side of the drive motor 4, containing a programmable logic controller (PLC) board. A pressure sensor 8 is installed at the outlet 3, and this pressure sensor 8 transmits data to the input module of the PLC board via electrical connection. Simultaneously, a float assembly 7 is also installed on the side of the control box 6, which is also electrically connected to the input module of the PLC board for real-time monitoring of water level changes. The drive motor 4 is connected to the output module of the PLC board and receives control commands from the PLC board. When the water level rises to a set height or the pressure sensor 8 detects abnormal pressure, the float assembly 7 triggers a microswitch, transmitting a signal to the PLC board. The PLC board, after judging according to a preset program, issues a stop or start command to the drive motor 4.

[0023] A water outlet pipe 9 is provided at the water outlet 3 of the pump body 1. A power cord 10 extending from the outside of the control box 6 connects the pump body 1 and the PLC board. These power cords 10 are tied and fixed to the water outlet pipe 9 to prevent the power cords 10 from being damaged.

[0024] The control box 6 has a float trough 11 on its side. The float assembly 7 includes a sliding float 12, a micro switch 13, and a micro switch 14. Micro switches 13 and 14 are respectively located on the upper and lower sides of the float trough 11. The sliding float 12 has an air chamber 15 inside and is slidably positioned within the float trough 11, floating with the water level. The float trough 11 is located on the side of the drive motor 4. When the water level drops below micro switch 13, the sliding float 12 disengages from micro switch 13. At this time, the cooling effect of the water on the drive motor 4 decreases, thus issuing a command to reduce the operating power of the pump body 1. When the water level drops below micro switch 14, continued operation of the pump body 1 may cause the motor to burn out. The sliding float 12 triggers micro switch 14, thereby controlling the submersible pump to stop operating.

[0025] A mounting base 16 is also provided at the bottom of the pump body 1. A filter disc 17 is provided between the mounting base 16 and the pump body 1. The filter disc 17 is basin-shaped and has a ring of filter holes 18 on its side wall. The filter disc 17 effectively prevents larger particles or impurities from entering the pump body 1, thereby avoiding clogging or wear on the blades 5 and improving the service life of the submersible pump.

[0026] A cutting assembly 19 is also installed inside the pump body 1. The cutting assembly 19 is fixedly installed at the bottom of the impeller. The cutting assembly 19 cooperates with the filter disc 17 to complete the cutting. The cutting assembly 19 includes a connecting rod 20 and a pair of cutting blades 21. The connecting rod 20 is fixed to the output end of the drive motor 4. The cutting blades 21 are located at the bottom of the connecting rod 20 and abut against the inner wall of the filter disc 17. When the submersible pump is running, the cutting blades 21 rotate with the rotation of the drive motor 4, cutting and crushing impurities near the filter disc 17, further preventing impurities from clogging the filter holes 18 or entering the pump body 1 and causing damage. At the same time, the design of the cutting assembly 19 effectively improves the submersible pump's ability to handle impurities, so that solid particles in the pumped medium can be pre-cut and crushed before entering the pump body 1, reducing the risk of clogging.

[0027] A support ring 22 is provided at the bottom of the mounting base 16, and a mounting ring 23 is also provided at the bottom of the water tank. The support ring 22 is located inside the mounting ring 23. A fixing block 24 can be detachably installed on the mounting ring 23. The fixing block 24 is used to press down the support ring 22 and fix the pump body 1. Through the cooperative design of the support ring 22 and the mounting ring 23, the submersible pump is more stable and reliable during installation, effectively reducing vibration and displacement during operation, and extending the service life of the equipment. The fixing block 24 is fixed to the mounting ring 23 by bolt connection, which is convenient for disassembly and assembly, facilitates equipment maintenance and repair, and ensures stable operation of the float assembly 7.

[0028] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
