Description

Technical Field

[0001] This utility model relates to the field of pipelines, and in particular to a motor assembly for pipelines. Background Technology

[0002] In the pipeline industry, it is often necessary to clean pipelines and monitor flow rates; however, the existing motor assembly structure is relatively complex, which leads to problems in installation, cleaning, and assembly, thus affecting durability.

[0003] For example, Chinese patent 202421353819.1 requires the setting of a central shaft structure in this design to ensure the stability of its rotation, which will also generate certain resistance, thus affecting the accuracy of the monitoring data.

[0004] For example, Chinese patent 202411535212.X describes a method to displace the tunneling ring through a transmission system in order to clean the pipeline. However, this method has significant limitations in actual cleaning and is also structurally complex. Utility Model Content

[0005] The main purpose of this utility model is to propose a motor assembly for pipelines, which aims to improve the existing motor assemblies for pipelines. It can not only measure the water volume, but also drain and clean the pipeline. Moreover, it has a simple and stable structure and is easy to install.

[0006] To achieve the above objectives, this utility model proposes a motor assembly for pipelines, comprising:

[0007] The housing is a hollow tube, the inner peripheral wall of the housing is a rotating cavity, and the outer peripheral wall of the housing is provided with a driving cavity;

[0008] The housing is provided with mounting parts at both ends, and the mounting parts are used to connect to the pipeline;

[0009] An impeller, comprising a hollow rotating tube and a plurality of blades disposed within the rotating tube, wherein the blades extend inward but not to the axis, and the rotating tube is pivotally mounted within a rotating cavity;

[0010] The rotating tube has a rotor on its wall surface;

[0011] The drive cavity is equipped with a stator that cooperates with the device.

[0012] In the first embodiment, by setting the impeller as a rotating tube and blades, the relative rotation of the impeller is achieved through the cooperation of the rotating cavity of the housing and the hollow rotating tube;

[0013] In the second embodiment, when the stator cooperates with the servo sensor, when the rotor rotates, the rotor generates magnetic shear force, and the stator obtains the predetermined flow rate through the change of magnetic flux of the servo sensor.

[0014] When the stator is energized, it drives the rotor to rotate, which in turn causes the impeller to rotate. When the flow rate or velocity is high, it can clean the pipe or drain water, effectively improving the ease of cleaning the pipe. Attached Figure Description

[0029] like Figures 1 to 4 As shown, a motor assembly for a pipeline includes:

[0030] The housing 1 is a hollow tube, the inner peripheral wall of the housing 1 is a rotating cavity 11, and the outer peripheral wall of the housing 1 is provided with a driving cavity 12;

[0031] The housing 1 has mounting portions 13 at both ends, which are used to connect to the pipe;

[0032] Impeller 2, the impeller 2 includes a hollow rotating tube 21 and a plurality of blades 22 disposed in the rotating tube 21, the blades 22 extending inward but not extending to the axis, the rotating tube 21 being pivotally mounted in the rotating cavity 11;

[0033] The rotating tube 21 is provided with a rotor 32 on its wall surface;

[0034] The drive cavity 12 is provided with a stator 31 that cooperates with the device.

[0035] In the first embodiment, by setting the impeller 2 as a rotating tube 21 and blades 22, the relative rotation of the impeller 2 is achieved through the cooperation of the rotating cavity 11 of the housing 1 with the hollow rotating tube 21;

[0036] In the second embodiment, when the stator 31 cooperates with the servo sensor, when the rotor 32 rotates, the rotor 32 generates magnetic shear force, and the stator 31 obtains the predetermined flow rate through the change of magnetic flux of the servo sensor.

[0037] When the stator 31 is energized, it drives the rotor 32 to rotate, thereby realizing the rotation of the impeller 2. When the flow rate or velocity is large, it can clean the pipeline or drain water, effectively improving the convenience of pipeline cleaning.

[0038] Specifically, the stator 31 is a magnetic induction coil, and the rotor 32 is a permanent magnet;

[0039] The ends of multiple blades 22 form a clearance zone 20, which prevents foreign objects from getting caught.

[0040] When used as a flow meter, the overall length can be reduced.

[0041] The blades 22 of the other flow meters and drive structures can also be modified according to actual needs.

[0042] In this embodiment of the invention, the magnetic induction coil is connected to a power source and is used to drive the permanent magnet to rotate.

[0043] Specifically, the magnetic coil is composed of multiple coils, which are arranged along the length of the housing 1 and are spaced apart along the periphery of the housing 1.

[0044] The permanent magnet is elongated.

[0045] In practical applications, longer coils can effectively increase magnetic flux. When used as a drive device, they can effectively ensure the rotational speed of impeller 2, improve rotational stability, and thus increase flow velocity and flow pressure.

[0046] In this embodiment of the invention, the magnetic coil is connected to a servo sensor, which is used to monitor changes in the magnetic circuit, thereby enabling the detection of flow rate and velocity. The flow rate can be monitored based on the number of rotations, and the velocity can be monitored based on the rotation speed.

[0047] Specifically, the housing 1 and the stator 31 are integrally injection molded or embedded in each other.

[0048] The housing 1 has a through hole through which a waterproof cable 4 is installed. The waterproof cable 4 extends into the drive cavity and connects to the stator 31, thus meeting different usage requirements and simplifying the installation structure.

[0049] The stator 31 can be integrally injection molded or be a post-installed structure.

[0050] In this embodiment of the present invention, a bearing 6 is provided between the outer wall of the rotating tube 21 and the driving cavity, and the rotating tube 21 rotates relative to the housing 1 through the bearing 6; two bearings are provided, the two ends of the rotating tube 21 are provided with a first stepped groove 51, and the two ends of the housing 1 are provided with a second stepped groove 52 that cooperates with the first stepped groove 51. The bearing is located between the first stepped groove 51 and the second stepped groove 52, thereby realizing the installation of the bearing. The bearing can be installed and fixed first, and then positioned by the mounting part 13.

[0051] Specifically, the mounting part 13 has a threaded, snap-fit, or heat-fused structure. The mounting part 13 is integrally formed with the housing 1 or fixed to the housing 1 by threading, welding, or ultrasonic welding. The mounting part 13 can be easily installed directly on the pipeline, improving the ease of installation.

[0052] In this embodiment of the present invention, the mounting portion 13 is provided at the outer end of the first stepped groove 51 and the second stepped groove 52. The end face of the mounting portion 13 is chamfered, which facilitates installation.

[0053] Specifically, the bearing is made of Teflon or ceramic material, thereby improving its rust prevention properties.

[0054] The mounting part is provided with a screwing part near the housing, or the housing is provided with a screwing part, which facilitates installation.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
