Description

Technical Field

[0001] This utility model relates to the field of electromagnetic water meter technology, and in particular to an electromagnetic water meter with continuous sampling function. Background Technology

[0002] Electromagnetic water meters, as key instruments for measuring the flow rate of conductive liquids (mainly water), are widely used in numerous fields such as urban water supply systems, industrial water monitoring, and water conservancy projects. In practical applications, to ensure water quality safety, analyze water flow composition, and monitor the operation of water supply and drainage systems, it is often necessary to sample and analyze the water in the pipelines. With the increasing demands for water quality and refined management across various industries, the development of electromagnetic water meters with efficient and continuous sampling capabilities has become an urgent need. This is of great significance for ensuring water safety, optimizing water resource utilization, and improving the operational efficiency of related systems.

[0003] Existing electromagnetic water meters mainly focus on flow measurement. Their structure typically consists of a measuring tube, electrodes, an excitation coil, and a signal processing unit. The measuring tube is used for water flow, the electrodes sense the electromotive force generated by the water flow, the excitation coil provides a magnetic field, and the signal processing unit processes the sensed signal to calculate the flow rate.

[0004] However, existing electromagnetic water meters are difficult to effectively and continuously sample water in pipelines. Traditional manual sampling interfaces can only achieve single sampling, which cannot meet the needs of real-time dynamic monitoring of water flow and continuous acquisition of water samples for analysis. It is difficult to collect representative water samples in a timely and accurate manner under complex and variable water flow conditions. Therefore, an electromagnetic water meter with continuous sampling function is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electromagnetic water meter with continuous sampling function, aiming to improve the problem in the prior art that it is difficult to collect representative water samples in a timely and accurate manner under complex and variable water flow conditions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electromagnetic water meter with continuous sampling function includes a water meter body, with connectors on both sides of the water meter body, a pipe threadedly connected to the outer wall of the connector, a sealing cap on the top of the water meter body, and a sampling component on the outer wall of the pipe.

[0008] The sampling assembly includes a sampling tube, one end of which is fixedly connected to the outer wall of the pipe, and the other end of which is fixedly connected to a flange. A support frame is fixedly connected to one end of the flange, and a cylinder is fixedly connected to one end of the support frame. A piston rod is fixedly connected to the output end of the cylinder. The piston rod passes through the flange and the sampling tube. A piston plate is fixedly connected to one end of the piston rod and is slidably connected to the inside of the pipe. A delivery pipe is fixedly connected to the outer wall of the sampling tube, and a collection box is fixedly connected to one end of the delivery pipe. A connecting assembly is provided on one side of the sealing cap.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes a connecting frame and a support column. One side of the connecting frame is fixedly connected to one side of the sealing cover, and one end of the support column is fixedly connected inside the connecting frame.

[0011] As a further description of the above technical solution:

[0012] A fixed column is fixedly connected inside the connecting frame, and the other end of the support column is fixedly connected to one end of the fixed column.

[0013] As a further description of the above technical solution:

[0014] A fixing frame is fixedly connected to one side of the water meter body, and a slot is provided inside the fixing frame.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the support column is slidably connected to a sliding rod one, and the outer wall of the fixed column is slidably connected to a sliding rod two.

[0017] As a further description of the above technical solution:

[0018] A spring is fitted on the outer wall of the support column, and the two ends of the spring are respectively fixedly connected to the inside of slide rod one and slide rod two.

[0019] As a further description of the above technical solution:

[0020] Both slide rod one and slide rod two have a locking block fixedly connected to one side.

[0021] As a further description of the above technical solution:

[0022] Anti-slip strips are fixedly connected to one side of both slide rod one and slide rod two, and the locking block is slidably connected inside the locking groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the piston rod is driven by the output end of the cylinder to slide in the flange and the sampling tube. The piston rod drives the piston plate to slide in the pipeline. By using the reciprocating motion of the piston plate, the water flowing in the pipeline is drawn into the sampling tube and then flows into the collection box through the delivery pipe. This achieves the effect of continuous sampling of water in the pipeline and solves the problem of difficulty in timely and accurate collection of representative water samples under complex and variable water flow conditions, thereby improving the flexibility of the electromagnetic water meter.

[0025] 2. In this utility model, by pressing the anti-slip strip on one side of the sealing cover, the sliding rod one and sliding rod two slide within the connecting frame, compressing the spring between them, causing the sliding rod to disengage the locking block from the slot of the fixed frame, thus achieving the disassembly of the sealing cover. During installation, the sealing cover is placed against the water meter body, the locking block slides into the fixed frame, and the spring rebounds, causing the locking block to engage with the slot. This achieves convenient disassembly and assembly of the water meter body and the sealing cover, solving the problem that the disassembly and assembly process of electromagnetic water meters and sealing covers is complex, requiring multiple tools, consuming a lot of time and manpower, and seriously affecting maintenance efficiency, thereby improving the convenience of maintaining electromagnetic water meters.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 An embodiment of this utility model is provided: an electromagnetic water meter with continuous sampling function, including a water meter body 1, with connectors 2 on both sides of the water meter body 1, a pipe 3 threadedly connected to the outer wall of the connector 2, a sealing cover 22 on the top of the water meter body 1, and a sampling component on the outer wall of the pipe 3, which is responsible for continuously sampling from the pipe 3.

[0034] The sampling assembly includes a sampling tube 4, one end of which is fixedly connected to the outer wall of the pipe 3, and the other end of which is fixedly connected to a flange 5. A support frame 6 is fixedly connected to one end of the flange 5, and a cylinder 7 is fixedly connected to one end of the support frame 6. The cylinder 7 drives the piston rod 8 to move by air pressure. The piston rod 8 is fixedly connected to the output end of the cylinder 7. The piston rod 8 passes through the flange 5 and the sampling tube 4. A piston plate 9 is fixedly connected to one end of the piston rod 8. The piston plate 9 contacts the inner wall of the pipe 3 by sliding, thereby realizing the extraction of water samples and ensuring the continuity and stability of sample collection. The piston plate 9 is slidably connected inside the pipe 3. A delivery pipe 10 is fixedly connected to the outer wall of the sampling tube 4. A collection box 11 is fixedly connected to one end of the delivery pipe 10, which is responsible for transporting the collected water samples to the collection box 11. A connecting assembly is provided on one side of the sealing cap 22.

[0035] Reference Figure 1 and Figure 4The connecting assembly includes a connecting frame 12 and a support column 14. One side of the connecting frame 12 is fixedly connected to one side of the sealing cover 22. One end of the support column 14 is fixedly connected to the inside of the connecting frame 12. A fixing column 15 is fixedly connected inside the connecting frame 12. The other end of the support column 14 is fixedly connected to one end of the fixing column 15. A fixing frame 13 is fixedly connected to one side of the water meter body 1. A slot 20 is provided inside the fixing frame 13 to securely install sliding rod 16 and sliding rod 17. Sliding rod 16 is slidably connected to the outer wall of the support column 14, and sliding rod 17 is slidably connected to the outer wall of the fixing column 15. A spring 19 is fitted on the outer wall of column 14. The two ends of the spring 19 are fixedly connected to the inside of slide rod 16 and slide rod 27 respectively. The spring 19 can provide the necessary restoring force to ensure that the slide rod can be smoothly reset during disassembly and assembly. A locking block 18 is fixedly connected to one side of slide rod 16 and slide rod 27, and an anti-slip strip 21 is fixedly connected to one side of slide rod 16 and slide rod 27. The locking block 18 is slidably connected inside the slot 20. Through the cooperation between the locking block 18 and the slot 20, the connection stability between the sealing cover 22 and the water meter body 1 can be ensured, and the components can be prevented from loosening or shifting.

[0036] Working principle: When sampling the water flowing inside pipe 3 during the use of this electromagnetic water meter, the piston rod 8 is first driven by the output end of cylinder 7 to slide inside flange 5 and sampling tube 4. The piston rod 8 is driven by force to drive the piston plate 9 at one end to slide inside pipe 3, thereby drawing the water inside pipe 3 into sampling tube 4, and then flowing into collection box 11 through delivery pipe 10 on the outer wall of sampling tube 4 for collection, thus achieving the effect of continuous sampling of water inside pipe 3.

[0037] When maintenance is required on the inside of the water meter body 1, first press the two anti-slip strips 21 on one side of the sealing cover 22, causing the sliding rod 16 and sliding rod 27 to slide inside the connecting frame 12. At the same time, the sliding rod 16 and sliding rod 27 will compress the spring 19 between them, thereby causing the sliding rod 16 and sliding rod 27 to drive the locking block 18 to disengage from the slot 20 inside the fixing frame 13. At this time, the sealing cover 22 can be removed from the top of the water meter body 1 to complete the disassembly. During installation, simply place the sealing cover 22 against the top of the water meter body 1, and the locking block 18 will slide into the fixing frame 13. The spring 19 will release the force and rebound, thereby driving the locking block 18 to reset and lock into the slot 20 to complete the fixation. This achieves the effect of easy disassembly and maintenance of the water meter body 1 and the sealing cover 22.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
