[0043] The present invention proposes a method for reducing noise in water pumping by a water pump.

[0044] Please refer to Figures 1 to 5 , in an embodiment of the present invention, the method for reducing noise in water pumping by a water pump includes the following steps:

[0045] S100. For each water pumping operation to be performed, collect the current air pressure data generated in the inlet hose when the water pump performs the water pumping operation through the inlet hose at a preset power.

[0046] In this embodiment, when collecting the air pressure data in the water inlet hose for each water pumping operation to be performed, a pressure sensor can be used to collect the air pressure intensity in the water inlet hose, and then the air pressure data can be obtained.

[0047] It should be specifically and clearly stated that, in this embodiment, the exemplary pressure sensor is a device acquisition device in the prior art that can collect the air pressure in a closed space. In this embodiment, it is only applied, and no improvement or design is made to the structure of the pressure sensor itself. Therefore, it will not be elaborated here one by one.

[0048] In this embodiment, by collecting the air pressure data in the water inlet hose for each water pumping operation to be performed, the present invention can instantaneously obtain the air pressure data in the water inlet hose when in use, enabling the present invention to achieve the function of instantaneously obtaining the air pressure data in the water inlet hose, being able to collect the air pressure data for each water pumping operation to be performed and realizing the noise reduction function, thus enhancing the flexibility of the present invention.

[0049] S200. According to the current air pressure data, determine the current decibel value of the sound generated by the water inlet hose disturbing the water source when the water pump performs the water pumping operation at a preset power;

[0050] In this embodiment, when the water pump performs the water pumping operation at a preset power, due to the presence of a cavity in the inner cavity of the water pump, when the water pump operates, the water hose disturbing the water source easily generates sound waves with the same frequency, and the propagation of these sound waves under different air pressure conditions is also different. Therefore, after obtaining the air pressure data, the corresponding decibel value of the sound can be collected when the water pump operates at a preset power.

[0051] It should be specifically and clearly stated that, in this embodiment, the exemplary preset power is preferably the rated power of the water pump, and the exemplary preset power can also be a preset power. Of course, in this embodiment, the technology used for collecting the decibel value is a device or apparatus in the prior art that can collect the decibel of sound. In this embodiment, it is only applied, and it will not be elaborated here one by one.

[0052] In this embodiment, by collecting the decibel value of the sound generated by the water hose disturbing the water source when the water pump performs the water pumping operation at a preset power, the present invention can accurately measure the decibel value of the sound generated when the water pump performs the water pumping operation at a preset power, providing accurate data for subsequent noise reduction operations and ensuring the efficiency and accuracy of noise reduction.

[0053] S300. Determine whether the current decibel value meets the preset requirement; wherein, the preset requirement is that the current decibel value is A, and A satisfies: A ≤ 30 db;

[0054] In this embodiment, by determining whether the decibel value meets the preset requirements, when the present invention is in use, it can determine whether noise reduction is required according to the determination result, without performing noise reduction every time the water pumping operation is carried out, improving the noise reduction efficiency and avoiding waste of resources.

[0055] S400. When the current decibel value does not meet the preset requirements, determine the range of air pressure change required to reduce the current decibel value to meet the preset requirements.

[0056] In this embodiment, by adjusting the air pressure change value, the present invention can also adjust the density of the air medium required for sound propagation, thereby reducing the decibel value during sound propagation and realizing the noise reduction function.

[0057] S500. Perform a pressurization operation on the water inlet hose according to the range of air pressure change to reduce the disturbance generated by the water inlet hose and make the current decibel value meet the preset requirements.

[0058] In this embodiment, by pressurizing the water inlet hose according to the air pressure change value to reduce the decibel value, making the decibel value of the sound in the water inlet hose meet the preset requirements, the present invention can reduce the decibel value of the sound by slowing down the sound propagation efficiency through pressurizing the water inlet hose during specific implementation, thereby realizing the noise reduction function.

[0059] It should be specifically and clearly stated that in this embodiment, for the purpose of facilitating the detection of the air pressure intensity in the water flow channel and pressurizing the water flow channel of the water pump, during specific use, an adjustment device should be installed at the water outlet end of the water pump. The adjustment device includes a connecting piece, a pressurizing piece, and a pressure sensor. The two ends of the connecting piece are respectively connected to the water outlet end of the water pump and the external pipeline, and a water flow channel that can connect the water outlet end of the water pump and the external pipeline is formed inside the connection, and the connection positions of the connecting piece with the water outlet end of the water pump and the external pipeline are both sealed. One end of the connecting piece close to the external pipeline forms a one-way valve through which water can only flow from the water pump to the external pipeline. Two installation holes are formed on the connecting piece and are both communicated with the water flow channel inside the connecting piece. The pressurizing piece and the pressure sensor are respectively installed in the two installation holes. The pressurizing piece and the pressure sensor both extend from the corresponding installation holes into the flow channel. When the water pump is performing the water pumping operation, the pressure sensor can be used to detect the air pressure environment in the water inlet hose, and when the sound generated by the water pumping in the air pressure environment inside the water pump exceeds the noise decibel, the pressurizing piece can be used to inflate the flow channel to achieve pressurization of the flow channel and the inside of the water pump, thereby enabling the sound to propagate more slowly in the air inside the water pump and realizing the function of reducing the sound.

[0060] In this embodiment, for each water pumping operation to be performed, the current air pressure data generated in the inlet hose when the water pump pumps water at a preset power is collected to immediately obtain the current data of each water pumping operation to be performed, providing accurate data guarantee for subsequent judgment on whether the current decibel value of the sound generated by the inlet hose disturbing the water source meets the preset requirements, whether to perform a pressurization operation on the hose, and the required pressure change value when a pressurization operation is needed. After obtaining the current air pressure data, according to the obtained current air pressure data, the current decibel value of the sound generated by the inlet hose disturbing the water source when the water pump pumps water at a preset power is determined. Through the obtained current decibel value, it can be judged whether the current decibel value meets the preset requirement of being less than or equal to 30 dB. When the current decibel value does not meet this preset requirement, the air pressure change value required to adjust and reduce the current decibel value to meet the preset requirement is determined to provide data guarantee for the noise reduction operation. Finally, the inlet hose is pressurized according to the air pressure change value and the disturbance of the inlet hose is reduced, so that the current decibel value meets the preset requirement. Furthermore, the present invention can relieve the air pressure environment in the inlet hose by pressurizing the air pressure in the inlet hose, making the gas environment in the inlet hose change smoothly without instantaneous change. Since the gas environment in the inlet hose does not change instantaneously, the inlet hose will not be disturbed or shaken in the water source area, avoiding the defect of generating noise due to the disturbance or shaking of the inlet hose in the water source area, and realizing the function of noise reduction.

[0061] In one embodiment, step S400 includes:

[0062] S410. When the current decibel value does not meet the preset requirement, obtain the difference decibel data set for reducing the current decibel value to meet the preset requirement;

[0063] In this embodiment, by obtaining the difference decibel value for adjusting the current decibel value to meet the preset requirement, the present invention can determine the decibel data that needs to be reduced during the noise reduction operation when in use, ensuring the accuracy of noise reduction.

[0064] S420. According to the difference decibel data set, sequentially obtain the air pressure change values corresponding to the difference decibel data by using Formula 1 to obtain the air pressure change range; where Formula 1 is:

[0065]

[0066] L P is the difference decibel data, P is the air pressure change value, P 0 is the reference pressure value, which is 2×10 -5 Pa.

[0067] In this embodiment, by using Formula 1 to obtain the air pressure change value, the present invention can accurately obtain the air pressure change value during use. According to the obtained air pressure change value, the air pressure intensity in the water flow channel of the water pump can be adjusted to the air pressure intensity corresponding to no noise generation, thereby realizing the function of noise reduction.

[0068] In one embodiment, after step S500, the method further includes:

[0069] S600. During the water pumping operation, collect the current decibel data in the water inlet hose in real time;

[0070] In this embodiment, during the water pumping operation, the current decibel data in the water inlet hose is collected in real time, so that during the implementation of the present invention, the sound decibel value in the water inlet hose can be determined immediately, and then it can be determined immediately whether the current decibel value in the water inlet hose is noise, providing real-time data for the noise reduction operation and ensuring the noise reduction efficiency.

[0071] S700. Take the current decibel data as the current decibel value, and repeat the step of judging whether the current decibel value meets the preset requirements until the water inlet hose is pressurized according to the air pressure change range to reduce the disturbance generated by the water inlet hose, so that the current decibel value meets the preset requirements, until the water pumping operation is completed.

[0072] In this embodiment, taking the current decibel data as the current decibel value and repeating the steps from step S300 to step S500 until the water pumping operation is completed, so that during the water pumping operation of the present invention, the sound decibel value in the water flow channel can be detected immediately and it can be determined whether the corresponding current decibel value of the sound is noise, ensuring the noise reduction effect during the water pumping operation.

[0073] In one embodiment, step S600 includes:

[0074] S610. For each water pumping operation to be performed, collect the current water flow rate and the current air pressure intensity in the water inlet hose in real time;

[0075] In this embodiment, by collecting the current water flow rate and the air pressure intensity in the water inlet hose in real time during the water pumping operation, the present invention can accurately and quickly determine the water flow condition of the water inlet hose during specific use, thereby providing accurate data support for the subsequent noise reduction operation.

[0076] S620. According to the current water flow rate and the current air pressure intensity, obtain the current decibel data in the water inlet hose.

[0077] In this embodiment, by obtaining the current decibel data in the water flow channel according to the current water flow rate and the current air pressure intensity, the present invention can accurately obtain the current decibel data in the water flow channel during use, so that the present invention can provide accurate decibel data for noise reduction operations and improve the noise reduction efficiency.

[0078] In one embodiment, step S500 includes:

[0079] According to the air pressure change range, perform a stepped pressurization operation on the water inlet hose within a preset pressure range and reduce the disturbance of the water inlet hose to make the current decibel value meet the preset requirements; wherein, the air pressure change value includes at least two adjacent preset pressure ranges in sequence.

[0080] In this embodiment, by adjusting the air pressure of the water inlet hose according to the air pressure change value when both ends of the water inlet hose are in a closed condition, so that the sound decibel value in the water inlet hose meets the preset requirements, the present invention can perform precise air pressure adjustment on the water inlet hose, improve the accuracy of noise reduction for the water inlet hose, and avoid waste of resources.

[0081] In some alternative embodiments, when specifically implementing the step of "According to the air pressure change range, perform a stepped pressurization operation on the water inlet hose within a preset pressure range and reduce the disturbance of the water inlet hose to make the current decibel value meet the preset requirements; wherein, the air pressure change value includes at least two adjacent preset pressure ranges in sequence", the air pressure change range can be divided into at least two adjacent preset pressure ranges in sequence; according to the preset pressure range, perform a stepped pressurization operation on the water inlet hose and reduce the disturbance of the water inlet hose to make the current decibel value meet the preset requirements.

[0082] In one embodiment, step S100 includes:

[0083] For each water pumping operation to be performed, when the water flow channel of the water pump is in a closed condition, collect the current air pressure data generated in the water inlet hose when the water pump pumps water at a preset power.

[0084] In this embodiment, by collecting the air pressure data of the water flow channel of the water pump and the water inlet hose when the water flow channel and the water inlet short pipe are in a closed condition, the present invention can avoid the influence of the external environment on the air pressure data during data collection and improve the accuracy of the collected air pressure data.

[0085] Based on the same technical concept, in a second aspect, the present invention also proposes a water pump water pumping noise reduction device, including:

[0086] The acquisition module collects the current air pressure data generated in the inlet hose when the water pump pumps water at a preset power for each water pumping operation to be performed.

[0087] The value acquisition module determines the current decibel value of the sound generated by the inlet hose disturbing the water source when the water pump pumps water at a preset power according to the current air pressure data.

[0088] The judgment module judges whether the current decibel value meets the preset requirements; wherein, the preset requirement is that the current decibel value is A, and A satisfies: A ≤ 30 db.

[0089] The analysis module, when the current decibel value does not meet the preset requirements, determines the air pressure change value required to adjust and reduce the current decibel value until it meets the preset requirements.

[0090] The air pressure adjustment module performs a pressurization operation on the inlet hose according to the air pressure change value and reduces the disturbance of the inlet hose, so that the current decibel value meets the preset requirements.

[0091] The water pump pumping noise reduction device provided by the embodiment of the present application adopts the water pump pumping noise reduction method in the above embodiment, and can solve the technical problem that when the instantaneous change of the air pressure environment in the hose caused by the suction of the water pump acts on the hose, it causes the hose to swing or shake, and finally causes the hose to disturb or shake in the water source area, forming noise.
