[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] like Figure 1-Figure 4As shown, the present invention provides an intelligent water pump, including a pump casing 100, an impeller 200, a motor 300, a transmission mechanism 500 and a controller 400; the impeller is rotatably arranged in the pump casing, and the transmission mechanisms are respectively configured on both sides of the pump casing, and the motor is respectively driven and connected to the two transmission mechanisms and is used to simultaneously drive the impeller to rotate through the two transmission mechanisms; the controller is configured with a frequency conversion module (not shown) for adjusting the power supply frequency, and the controller is electrically connected to the motor.

[0034] Specifically, the motor in the intelligent water pump of this embodiment transmits power through the two transmission mechanisms. The two transmission mechanisms are arranged on both sides of the pump housing and drive the impeller to rotate from both sides of the impeller respectively.

[0035] In actual use, the controller can process the frequency of the power supply network through the frequency conversion module. For example, the frequency of the national power grid is 50Hz / S. Correspondingly, the speed of the motor at this power supply frequency is 50Hz×60 seconds=3000 rpm. In order to improve the working efficiency of the motor, the power supply frequency is processed to 100Hz / S through the frequency conversion module. At this time, the speed of the motor is increased from 3000 rpm to 6000 rpm, thereby increasing the head and flow rate by increasing the speed of the motor.

[0036] Correspondingly, since the motor runs at a high speed, in order to ensure that the impeller can rotate smoothly in the pump casing, two transmission mechanisms are arranged on the outside of the pump casing. The two transmission mechanisms simultaneously transmit power from both sides to drive the impeller to rotate, and both sides of the impeller can obtain power provided by the transmission mechanism to drive. The motor drives the two transmission mechanisms to rotate synchronously and at the same speed, so that the impeller can run smoothly in the pump casing to ensure stability under high-speed operation of the impeller.

[0037] Furthermore, the transmission mechanism includes a cover 501, a first synchronous wheel 502, a synchronous belt 503 and a second synchronous wheel 504, the synchronous belt is wound between the first synchronous wheel and the second synchronous wheel, and the first synchronous wheel and the second synchronous wheel are both rotatably arranged on the pump casing; the impeller is located between the two synchronous wheels, the first synchronous wheel is used to drive the impeller to rotate, and the motor is used to drive the second synchronous wheel to rotate respectively, and the cover is arranged on the pump casing and covers the first synchronous wheel, the synchronous belt and the second synchronous wheel.

[0038] Specifically, for the transmission mechanism, the synchronous belt is used to transmit power, the first synchronous wheels symmetrically arranged on both sides of the impeller are used to drive the impeller to rotate, and the second synchronous wheels are synchronously driven by the motor.

[0039] Preferably, in order to achieve a compact design of the overall structure of the equipment and to reduce the impact of configuring two transmission mechanisms on the increase in the overall volume of the equipment, a rotatable main shaft 101 is provided on the pump casing, and the two ends of the main shaft respectively extend to the outside of the pump casing and extend into the cover casing; wherein, the impeller is provided on the main shaft, and the first synchronous wheel is provided on the main shaft.

[0040] Specifically, the pump housing is equipped with the main shaft, so that a single main shaft can simultaneously meet the installation requirements of the first synchronous wheel and the impeller in the transmission mechanisms on both sides. The first synchronous wheels are symmetrically mounted at both ends of the main shaft to drive the main shaft to rotate outside the pump housing. The impeller is mounted on the main shaft inside the pump housing. This way, power is transmitted through the single main shaft, which not only enables the two transmission mechanisms to rotate reliably and synchronously, but also reduces the use of additional transmission components and makes the overall structure of the equipment more compact.

[0041] Furthermore, mounting holes (not marked) are provided on both sides of the pump housing, a mounting barrel 102 is provided in the pump housing, the mounting barrel is sealed and connected between the two mounting ports, and the motor is provided in the mounting barrel.

[0042] Specifically, the mounting barrel is disposed within the pump housing and located on the inner side of the water inlet of the pump housing. This allows the motor to be sealed and installed through the mounting barrel, fully utilizing the internal space of the pump housing. Preferably, to reduce the water resistance created by the mounting barrel to the water flow entering the water inlet, the centerline of the water inlet can be positioned above the mounting barrel. The mounting barrel has an overall circular barrel-shaped structure. The arc surface of the mounting barrel can guide the water flowing into the water inlet to flow smoothly toward the impeller at the top, thereby ensuring smooth water flow into the pump housing.

[0043] Furthermore, the motor is a dual-shaft motor, the second synchronous wheel is arranged on the motor shaft at the corresponding end of the motor, and the axis of the motor shaft of the motor and the axis of the main shaft are parallel to each other.

[0044] Specifically, in order to facilitate the output of power to the transmission mechanisms on both sides, the motor adopts a dual-shaft structure, so that the second synchronous wheel is installed through the motor shafts at the corresponding ends.

[0045] The controller can be implemented as a control module in a conventional intelligent motor, while the frequency conversion module in the controller can be implemented as a frequency converter in a variable frequency motor. The frequency converter can adjust the frequency within a range of 0-400 Hz according to the operating requirements of the motor.

[0046] In addition, to meet remote monitoring requirements, the controller is also equipped with a wireless communication module (such as a 4G module or a 5G module), enabling remote communication control. The controller is also equipped with a display screen, and the motor is equipped with a current transformer and a voltage transformer. These current transformers and voltage transformers are electrically connected to the controller, respectively, and the motor current and voltage are displayed on the display screen. In actual use, the water power of the water pump can be calculated from the flow rate and head, and the electrical power can be calculated from the current and voltage, which can further be used to calculate the pump efficiency. In this way, the controller can display the motor current and voltage, the water pump flow rate, and the water pump efficiency on the display screen.

[0047] Based on the above technical solution, optional, such as Figure 1 and Figure 5 As shown, the flow detection module includes a support frame 1, a detection pipe 2 and a flow meter 3. The support frame is arranged in the pump casing, the detection pipe is arranged on the support frame and suspended in the pump casing, and the sensor 31 of the flow meter is arranged in the detection pipe and electrically connected to the controller.

[0048] Specifically, the flow detection module 500 is integrated and installed in the pump housing 100 . The detection pipe 2 in the flow detection module 500 is set in the pump housing 100 , and the sensor 31 of the flow meter 3 in the flow detection module 500 is arranged in the detection pipe 2 .

[0049] For the detection pipeline 2, the detection pipeline 2 has a straight pipe structure as a whole, and the ratio of the flow path length to the flow path diameter of the detection pipeline 2 meets the straight pipe section length requirement required by the national standard, that is, the length of the detection pipeline 2 is not less than 5 times the diameter of the water flow channel in the detection pipeline 2.

[0050] During actual use, water flows into the pump housing 100 , and the water in the pump housing 100 also flows into the detection pipe 2 . The water flowing through the detection pipe 2 passes through the sensor 31 and then the flow rate is detected by the flow meter 3 .

[0051] Since the flow path length and flow path diameter ratio of the detection pipe 2 meet the straight pipe section length required by national standards, the water flow velocity in the detection pipe 2 is evenly distributed, thereby improving the detection accuracy of the sensor 31.

[0052] In addition, the detection pipe 2 is relatively short in length, thereby meeting the installation requirements of the flow meter 3 under the condition of a relatively short length. In this way, the detection pipe 2 can be directly integrated into the pump housing 100 without the need to configure an additional pipe outside the pump housing 100 to form a straight pipe section.

[0053] Further, such as Figure 4 As shown, a first guide plate 21 is further provided in the detection pipe 2 . The first guide plate 21 extends along the axis of the detection pipe 2 and is arranged on the water inlet side of the sensor 31 .

[0054] Specifically, by configuring a first guide plate 21 in the detection pipe 2, the first guide plate 21 can better guide the water flow into the detection pipe 2. The first guide plate is arranged along the axial direction of the detection pipe 2, so that the water flow in the detection pipe 2 can flow more quickly and smoothly, thereby better balancing the water flow rate in the detection pipe 2. Furthermore, a second guide plate 22 is also provided in the detection pipe 2. The second guide plate 22 extends along the axis of the detection pipe 2 and is arranged on the water outlet side of the sensor 31. Specifically, the second guide plate 22 is also configured on the water outlet side of the sensor 31 in the detection pipe 2 to guide the water flow in the detection pipe 2 to be smoothly discharged, thereby more effectively ensuring that the water flow rate in the detection pipe 2 is uniform.

[0055] Similarly, if Figure 6 As shown, a mounting cavity 23 is formed inside the detection pipe 2 , and a water inlet channel 24 and a water outlet channel 25 are formed in the detection pipe 2 , and the water inlet channel 24 and the water outlet channel 25 are respectively connected to the mounting cavity 23 .

[0056] Specifically, in order to more effectively reduce the overall length of the detection pipeline 2 and meet the installation requirements of the sensor 31, an installation cavity 23 can be formed in the middle part of the inspection pipeline to install the sensor 31, and an inlet channel 24 and an outlet channel 25 with a smaller diameter than the installation cavity 23 are provided on both sides of the installation cavity 23. The inlet channel 24 and the outlet channel 25 are used to meet the requirements of the straight pipe section length during flow meter 3 detection. At the same time, since the diameters of the inlet channel 24 and the outlet channel 25 are smaller, the overall length of the detection pipeline 2 can be more effectively shortened.

[0057] Furthermore, along the water flow direction in the pump housing 100 , the outer dimensions of the detection pipe 2 gradually increase from the water inlet channel 24 to the installation cavity 23 , and gradually decrease from the installation cavity 23 to the water outlet channel 25 .

[0058] Specifically, since the detection pipe 2 is suspended in the pump casing 100 through the support frame 1, in order to reduce the large water resistance caused by the detection pipe 2 to the water flow in the pump casing 100, the water inlet end and the water outlet end of the detection pipe 2 are both set to a conical structure to play a role in guiding the water flow, thereby reducing the water resistance caused to the water flow.

[0059] In some embodiments, in order to facilitate the connection of the sensor 31, a wiring channel (not marked) is provided in the support frame 1, and the cable between the controller and the sensor 31 is arranged in the wiring channel.

[0060] The flow detection module may be installed in the water inlet or outlet of the pump housing as required.

[0061] The present invention also provides a water supply system, comprising a water supply pipe and the above-mentioned intelligent water pump, wherein the intelligent water pump is connected to the water supply pipe.

[0062] Compared with the prior art, the advantages and positive effects of the present invention are: by configuring two transmission mechanisms on the pump casing, the motor drives the impeller to rotate simultaneously on both sides of the impeller through the two transmission mechanisms, so as to effectively increase the impeller torque, and make the two ends of the impeller evenly stressed so that the rotation can be more balanced. Correspondingly, the frequency conversion module can change the frequency of the power supply network to double the speed of the motor, so that the impeller can rotate smoothly under the drive of the transmission mechanisms on both sides, so as to increase the head of the intelligent water pump and improve the water supply efficiency of the intelligent water pump.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
