Description

Technical Field

[0001] This utility model relates to the technical field of liquid level measuring devices, specifically a non-full pipe flow meter. Background Technology

[0002] Non-full-pipe electromagnetic flow meters are used in pipelines in municipal and other places. The application scenarios of non-full-pipe electromagnetic flow meters are generally large-diameter pipelines. The non-full-pipe electromagnetic flow meter is installed in the pipeline that transports water and coal slurry through a flange. When water and coal slurry pass through the inside of the non-full-pipe electromagnetic flow meter, the flow rate and velocity of water and coal slurry can be monitored in real time, so that water and coal slurry are mixed in a certain proportion.

[0003] For pipelines with pre-defined installation locations, installing a large-diameter non-full-pipe electromagnetic flowmeter requires extensive earthwork at the installation location to ensure sufficient space between pipes for the flowmeter. Furthermore, for applications with large orifices, conventional non-full-pipe electromagnetic flowmeters are typically large-diameter, resulting in high manufacturing costs and difficult installation. To address these shortcomings, we propose a non-full-pipe flowmeter to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a non-full-pipe flow meter, which solves the problems of large-diameter non-full-pipe electromagnetic flow meters not being easily installed in pipelines and the installation accuracy of non-full-pipe electromagnetic flow meters being affected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-full-pipe flow meter, comprising a measuring tube, a mounting bracket, a liquid level measuring module, a flow velocity measuring module, lead wires, and a core processor. The mounting bracket has cleaning mechanisms on both its upper and lower sides, and each cleaning mechanism includes:

[0006] The outer walls of the first bearing and the second bearing are fixedly connected to the upper and lower sides of the mounting bracket, respectively. The inner surfaces of the first bearing and the second bearing are provided with an upper cleaning component and a lower cleaning component for cleaning impurities on the upper and lower outer walls of the measuring tube located on the mounting bracket.

[0007] The blades, the two sets of blades are respectively fixedly connected to the inner surfaces of the first bearing and the second bearing;

[0010] Preferably, the inner wall of the first bearing is fixedly connected to an upper frame for supporting the upper screw, one end of the upper threaded plate is fixedly connected to one side of the upper cleaning member, and the other end of the upper cleaning member is threadedly sleeved on the outer wall of the upper screw.

[0011] Preferably, the inner surface of the second bearing is fixedly connected to a lower frame for supporting the lower screw, and one end of the lower threaded plate is threaded onto the outer wall of the lower screw.

[0012] Preferably, a base plate is fixedly connected to the bottom surface of the lower threaded plate, and the other end of the base plate is fixedly connected to the bottom surface of the lower cleaning component.

[0013] Preferably, one end of the upper screw and the lower screw is provided with a set of locking components. The locking components include threaded cylinders that are fixedly connected to the inner walls of the upper frame and the lower frame respectively, and threaded rings that are threadedly sleeved on the outer walls of one end of the upper screw and the lower screw respectively.

[0017] This utility model discloses a non-full-pipe flow meter, which has the following beneficial effects: This non-full-pipe flow meter changes the traditional method of installing large-diameter non-full-pipe electromagnetic flow meters through flanges to pipes, and instead uses an insertion-type non-full-pipe electromagnetic flow meter, which can be directly installed to the pipe through a mounting bracket. This eliminates the need for extensive excavation around the pipe at a pre-set location. Furthermore, the insertion-type non-full-pipe electromagnetic flow meter has a compact structure, effectively saving manufacturing costs. The mounting bracket is equipped with a cleaning component that can be adjusted according to the different sizes of the insertion-type non-full-pipe electromagnetic flow meter, effectively preventing excessive impurities from adhering to the outer wall of the insertion-type non-full-pipe electromagnetic flow meter, thereby reducing the impact on the measurement accuracy of the insertion-type non-full-pipe electromagnetic flow meter.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] This application provides a non-full-pipe flow meter, which solves the problems of large-diameter non-full-pipe electromagnetic flow meters not being easily installed in pipelines and the installation accuracy of non-full-pipe electromagnetic flow meters being affected, and realizes the insertion installation of non-full-pipe electromagnetic flow meters.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] This utility model discloses a non-full pipe flow meter.

[0032] According to the appendix Figure 1-8 As shown, it includes a measuring tube 1, a mounting bracket 2, a liquid level measuring module 3, a flow rate measuring module 4, a lead wire 6, and a core processor 7. The installation method of the core processor 7 is not limited to... Figure 1 and attached Figure 2 The SET801 series insertion-type non-full-pipe flow meter, as shown in the split installation diagram, comprises components such as measuring tube 1, mounting bracket 2, liquid level measurement module 3, flow velocity measurement module 4, lead wire 6, and core processor 7. The mounting bracket 2 is fixed inside the pipe by welding. One end of the measuring tube 1 is inserted into the pipe, and the mounting bracket 2 provides stable support for the end of the measuring tube 1 inside the pipe. The inside of the measuring tube 1 is filled with potting compound 5 to meet its waterproof requirements. The liquid level measurement module 3 is a capacitive liquid level measurement system, mainly measuring the liquid level of the medium in the pipe and calculating the flow rate based on the liquid level. The cross-sectional area A(t) of the medium in the pipe (with known pipe inner diameter) is calculated. The flow velocity measurement module 4 adopts the Faraday electromagnetic induction principle and mainly includes an electromagnetic coil and a pair of measuring electrodes. The measuring electrodes measure the electrical signal generated by the fluid cutting the magnetic lines of force generated by the electromagnetic coil to calculate the flow velocity v(t) of the medium in the pipe. The measuring tube 1, the liquid level measurement module 3 and the flow velocity measurement module 4 form a measurement module. The measurement module obtains the cross-sectional area and flow velocity signal of the medium in the pipe and inputs it to the core processor 7 through the lead wire 6. The core processor 7 calculates the flow rate Q(t) = v(t) * A(t) of the medium in the pipe.

[0033] See attached document Figure 1 and appendix Figure 4-7The mounting bracket 2 is equipped with cleaning mechanisms 8 on both its upper and lower sides. These mechanisms effectively scrape away impurities adhering to the outer wall of the measuring tube 1, preventing them from affecting the measurement accuracy. Each cleaning mechanism 8 includes a first bearing 81 and a second bearing 82. The outer walls of the first bearing 81 and the second bearing 82 are fixedly connected to the upper and lower sides of the mounting bracket 2, respectively. The inner surfaces of the first bearing 81 and the second bearing 82 are equipped with an upper cleaning component 83 and a lower cleaning component 84 for cleaning impurities from the outer walls of the measuring tube 1 on both sides of the mounting bracket 2. The upper cleaning component 83 and the lower cleaning component 84 clean the outer walls of the measuring tube 1 on both sides of the mounting bracket 2. The materials of the upper cleaning component 83 and the lower cleaning component 84 include insulating scrapers, etc., depending on the specific requirements. In practical applications, two sets of blades 85 are fixedly connected to the inner surfaces of the first bearing 81 and the second bearing 82, respectively. That is, the two sets of blades 85 are fixedly connected to the inner rings of the first bearing 81 and the second bearing 82, respectively. The outer rings of the first bearing 81 and the second bearing 82 are fixedly connected to the upper and lower sides of the mounting bracket 2, respectively. Specifically, under the impact of the medium in the pipeline, the blades 85 are driven to rotate, thereby causing the inner rings of the first bearing 81 and the second bearing 82 to rotate in a ring along the outside of the measuring tube 1. This, in turn, causes the upper cleaning component 83 and the lower cleaning component 84, which are connected to the inner rings of the first bearing 81 and the second bearing 82, to rotate in a ring along the outside of the measuring tube 1, so that the upper cleaning component 83 and the lower cleaning component 84 can clean the impurities adhering to the outer wall of the measuring tube 1 in an all-round manner.

[0034] See attached document Figure 4 and attached Figure 6 The upper adjustment component 86 is used to adjust the distance between the upper cleaning component 83 and the measuring tube 1 of different sizes. The upper adjustment component 86 includes an upper screw 862 and an upper threaded plate 863 for adjusting the position of the upper cleaning component 83. The inner wall of the first bearing 81 is fixedly connected to an upper frame 861 for supporting the upper screw 862. One end of the upper threaded plate 863 is fixedly connected to one side of the upper cleaning component 83, and the other end of the upper cleaning component 83 is threaded onto the outer wall of the upper screw 862.

[0035] See attached document Figure 5 and attached Figure 7 The lower adjustment component 87 is used to adjust the distance between the lower cleaning component 84 and the measuring tubes 1 of different sizes. The lower adjustment component 87 includes a lower screw 872 and a lower threaded plate 873 for adjusting the position of the lower cleaning component 84. A lower frame 871 for supporting the lower screw 872 is fixedly connected to the inner surface of the second bearing 82. One end of the lower threaded plate 873 is threaded onto the outer wall of the lower screw 872. A base plate 874 is fixedly connected to the bottom surface of the lower threaded plate 873. The other end of the base plate 874 is fixedly connected to the bottom surface of the lower cleaning component 84. The base plate 874 contacts the bottom surface of one end of the measuring tube 1 inserted into the pipe, so that the base plate 874 can clean the impurities adhering to the bottom surface of one end of the measuring tube 1.

[0036] See attached document Figure 8 Each end of the upper screw 862 and the lower screw 872 is provided with a locking assembly 9. The locking assembly 9 includes a threaded cylinder 91 that is fixedly connected to the inner wall of the upper frame 861 and the lower frame 871 respectively, and a threaded ring 92 that is threadedly sleeved on the outer wall of one end of the upper screw 862 and the lower screw 872 respectively. One end of the threaded ring 92 is threaded into the inside of the threaded cylinder 91. Both the inner and outer walls of the threaded ring 92 are provided with a set of threaded teeth. The two sets of threaded rings 92 are threadedly connected to the outer walls of the upper screw 862 and the lower screw 872 respectively through the threaded teeth of their inner walls. The threaded rings 92 are threadedly connected to the threaded teeth of the inner wall of the threaded cylinder 91 through the threaded teeth of their outer walls.
